Different Open Source communities have different +"flavours" regarding culture, communication climate, structure, decision-process +etc. PyPy was born out of the Python Community and share some of it?s characteristics +which have had a huge influence on the project process so far. Aspects such as +distributed/dispersed development and the supporting practices and infrastructure in place +to quality assure software development in a collaborated manner are part of this important +influencing factor. + +- The Agile factor. Almost a subset of the F/OSS/Python community factor - agile +practices that has been in use since the inception of the project, that in fact have +been the main drivers of the project are very much inspired by other projects in the +Python community. A key factor in this influencing factor is the Python version of +"sprinting". We will present this "agile" practice, explain and trace it?s origins within the +Python community and identify which of the main agile practices inspired the Python world +to go "sprinting" - a key technique today not only for the PyPy project but also for all main +Python projects. We will also touch on aspects such as Test Driven Development and +explain how these are implemented in PyPy. + +- The EU factor. PyPy is the first F/OSS community that organized themselves into an +EU-project, recieving EU-funding. It has had a huge impact on the project, and it is +important to identify how EU project and process requirements can be "weaved" into +and Agile F/OSS project - a challenge indeed. The EU-funding has been and still is an +enourmous opportunity, the project would not have had the rapid progress and impact it +is now having without the funding. It is also very important to note that without striking the +right balance between the three main influencing factors (F/OSS, agile and EU-funding) this +factor might also prove to be a "showstopper", something that might influence the PyPy +community negatively. This is a constant challenge - we explain here how we created +our process and added a "consortium-level" structure to the F/OSS community +and the steps we took in order to mitigate this risk. + +Our conclusion so far in the project is that we believe that the practice of "sprinting", +as being used in the PyPy project, makes Agile and Distributed/dispersed workstyles +more possible to combine. We also believe it is a very useful practice for creating value +and ensuring quality in a projects with hybrid cultures and methodologies.

The +key to a lively and working community is the people factor, as always and of course so for the +Python community as well. The PyPy community ------------------ +The PyPy project is one of the four large language implementation projects in the Python community. +PyPy grew from the architectural experiences from previous successful Python projects and this +prior community experience was vital for the evolving of the PyPy community due to the established +trust in expert skills of the core developers starting PyPy - again the people factor.Thus making it easier +recruit people into the PyPy community. + +The PyPy project inherited the focus on collaborative approaches and open communication climate. +The nature of using sprints as a core technique as a way to kick-start the project as well as moving +the sprints to different locations as a strategy to encourage participation by meeting people locally +are clear examples of this. During the period of 2003-2004 6 sprints were arranged in various european +cities, hosted by universities and private persons, participation funded privately.

In PyPy, Subversion is being used, covering both +program files and documentation. Several automated mailing lists makes sure that every +person involved receives instant notification on changes - supporting peer review on all levels. + +PyPy is also in some sense very much test-driven. PyPy is one of the +primary users of a separate F/OSS project called the py.test, tools for +automated testing with PyPy developers contributing improvements to py.test. +py.test contains a sophisticated system for running tests against the Python +Standard Library, with automatic selection of overriding tests in case there is +internally developed code that overrides the Python Standard Library - +important compliance features when the project is about language implementation. +There are also powerful mechanisms for disabling specific tests and for producing +useful traceback output. There are also automatically generated web pages that +show the status of all tests as per the latest checked in test results. + +The main communication channels between developers involved in PyPy is +to discuss over IRC (Internet-Relay-Chat) - open for all that are interested. +Several mailinglists for discussions and information is also used. Webpages, +documentation, tutorials, talks and papers etc are all available on the central +developer server for everyone.A very useful feature that really supports information +and communication (the author can attest from her own experience) are the public +email archives covering the key mailinglists - going back to start of 2003. + +An extensive coding guide, published on codespeak.net (development website) +serves as an introduction to the set of specifications being used while coding PyPy. +The coding guide covers not only naming conventions but also +design, test and documentation guidelines. + +Now - all this infrastructure is being used in almost all larger open source projects and +quite a few of them are much more hierarchial and non-transparent in their communication. +In PyPy there is no hierarchy for recieving commit-rights. A newcomer to PyPy can instantly +recieve an account on the development server, with full commit rights to the version control +system. The reason why there are no constraints is that the process is very much +self-organized and managed by the developers from a social level +(peer review, code review, supporting communication channels, coaching, mentoring) and with +strong automated tools covering tests, versions and back ups covering the technical level. + +In a distributed and dispersed workstyle these two (social and technical) levels needs to be +consistent and support each other, discrepancies would be immediately noticed. As stated +before - the people factor is again evident and in order to encourage participation and +contribution there has to be trust as well as a supportive environment in order to manage a +virtual collaborative workspace. + Supporting practices -------------------- + +Another good example of the collaborative nature of the Python community is the way +which the various projects share best practices. Core developers in the PyPy project picked +up the practice of synchronization meetings as a powerful way of supporting distributed and +dispersed development, implemented by Canonical. + +Sync-meetings are weekly short coordination meetings between developers, open to +all developers active in the PyPy community, usually but not necessarily involving aspects +of EU-funded work on deliverables. These 30 minute IRC-meetings serve a weekly +synchronisation for regular discussions and integration of ongoing work. Meetings are +prepared with an agenda sent out to pypy-dev and minutes are distributed on pypy-dev and +archived in the repository with publicly accessible links.Preparing, managing and documenting +the meetings is rotated between active developers and is self-organized as well. + +Sync-meetings have proven to be a very good complement to a process in which the project +sprints every 6th week. Sync-meetings keep cohesion as well as a team focus-and-feel for +the dispersed workstyle between sprints. Influencing factors: agile practices in PyPy ============================================ -TDD ---- - -XP --- - Sprints ------- +PyPy first started during a one-week meeting, a "sprint", held at Trillke-Gut +in Hildesheim February 2003. The sprint was inspired by practices used by other +Python projects such as Zope3. Originally the sprint methodology used in the +Python community grew from practices applied by the Zope Corporation. Their +definition of a sprint was: "two-day or three-day focused development session, +in which developers pair off together in a room and focus on building a +particular subsystem". + +Tres Seaver from the Zope Corporation, one of the instigators of the sprint +method as it is used in the Python community says the following about how they +evolved the method during 2001 and 2002: + +"The motivation was to begin using as much of XP as would fit to accelerate Zope3 +development. Given the different development culture of the Zope community +(framework-centric, distributed, no "business user" present), some of the XP mantras /practices +couldn't be done directly. We decided to try to do "as much XP as possible" for short, +highly-focused sessions, with all active committers colocated." + +As Zope Corporation as well as other Python projects such as PyPy have seen is +that sprints have goals beyond the creation of software: + +- It helped evolving the community through participation and hands-on contact +with the core developers. + +- It is a live training session not only in producing code but also in the development +methods being used (TDD, pairprogramming etc, the sprint method in itself). + +- It supports activities such design decisions and high-level requirements discussions, +creating cohesion and understanding as well as minimizing risks with dispersed/distributed +work where these kind of activities can be really difficult to manage. + +The reason for naming the method sprinting, not at all connected to Scrum and +the usage of sprints in that context, according to Tres Seaver is: + +"... because of the fact that we weren't doing XP in its proper sense, which is +more like running a long-distance race, where pacing oneself is critical. +Instead, we were pushing as fast as possible in order to maximize the benefit of limited +face time. Of all the XP practices, the one we gave shortest shrift to +is "no overtime": as sprints often go far into the evening (or even +the wee hours of the morning." + +The sprint method, as well as key aspects of F/OSS supportive infrastructure and +practices was established within the project before PyPy recieved it?s EU-funding. +Thus, in the proposal,we put much emphasis on the methodology in itself when +designing the consortium level process. Examples of how this was done was that +we created a methodology objective, specific deliverables regarding documentation +of the sprint-driven methodology as well as designing a process during the 2 years +of funding in which the project and the developers sprints every 6th week. This was +taken into account when estimating the budget, adding costs for travel and +accommodation for all partner organizations - covering 14 sprints during the 2 years. +So far during the funded part of the project we have organized 10 sprints - successful +sprints from both a development, recruiting, dissemination and networking aspects. +Another important fact is that the sprints are organized by the developers and as such is +another good example of the collaborative manner of the culture of the project and the +community. + +Why did PyPy choose sprinting as a key technique? It is a method that fits +distributed teams well because it gets the team focused around visible +challenging goals while working collarobatively (pair-programming, status +meetings, discussions etc) as well as acceleratedly (short increments and +tasks, "doing" and testing instead of long startups of planning and +requirement gathering, continuous integration). This means that most of +the time a sprint is a great way of getting results and getting new +people aquainted - a good method for dissemination of knowledge and +learning within the team. + +A key insight, worthwhile for other EU-projects to ponder, is how an agile +process like sprinting is much more suited for creative work between groups of +distributed people. Traditional software development, as well as traditional +project management techniques have a tendency to hinder creativity due to the +inbuilt over-structured, segmented and control-oriented approach which in most +cases ends in less quality when results are being measured. + EU-project practices ==================== -The formal project organization required by the EU imposed more structure on -the previous more free-floating agile process. Roles and responsibilities where -staked out,conforming with the requirements of the roles but delegating as much -as possible of the responsibilities and decision-making to the core developers. -The strategy was to keep "conceptual integrity" (Brooks) of the vision and the -idea in the hands of the core developers. A somewhat negative result was the -added workload and responsibility on developers regarding EU related work. It -was also a conscious strategy to employ the same version-control/review based -scheme regarding EU documents and Consortium level issues as those being used -in the technical development. - -It remains a challenge for all partners of the consortium, universities and -companies alike, to connect an ongoing medium-scale open-source project with EU -regulations and requirements - not to speak of the fact that companies need to -fund 50% of the costs themselves. It is, in fact, too early to judge the -overall success of our approaches although we are confident that things work -out reasonably well. - Consortium structure -------------------- +Key requirements regarding organizational structures of an Framework Programme 6 +EU-project are: +- a consortium of partners performing the work described in the contract +- a project co-ordinator managing contract administration and communication +between consortium and the Commission +- a project manager, responsible for the project reaching it?s goals within the +timeframe and budget + +The challenge was to design a project process that created a minimal amount of +changes to the structure being in use in the F/OSS project. It was especially +important to maintain an open and transparent communication, even for decision on +consortium level and such. There was a fear of the EU-project adding "top-down" +structures on the F/OSS work and on the core developers instigating the project. + +We identified a minimalistic approach of management roles (project co-ordinator, project +manager, assistant project manager) and created a management team to make sure +that there was collaboration between these roles. Although the responsibility rested on +the different management roles and the management team the strategy implemented was to +delegate as much as possible of the responsibilities and decision-making to the core developers. + +The strategy was to keep "conceptual integrity" (Brooks) of the vision and the +idea in the hands of the core developers. A somewhat negative result was the +added workload and responsibility on developers regarding EU related work. +The core developers were organized into a technical board, responsible for planning +and coordinating the development work between the partners. + +This structure was the most difficult to design and implement due to the very different nature +of it?s purpose compared to the collaborative, self-organized nature of the F/OSS project - +again it succeeded the way it has because of the core developers acting as an interface between +the developer group and the consortium level work - again we see the trust aspect and the people +factor in play. + +Sprints were budgeted for and designed into the process, together with a timeplan +for all deliverables. The project was divided into three different phases, depending +on the nature of the workflow. In that sense you could describe the EU-part of the project +as a fixed-contract style of work, but with timeplan, deliverables and work package descriptions +on a high-level, not broken down into more granular tasks. + Resource tracking and reporting ------------------------------- +The nature of reporting on a consortium level is very much focused on the costs +incurred by each partner compared to budget, by the consortium on a specific +workpackage and of the consortium overall. The consortium is free to reallocate +budgeted manmonth funding between partners during the project. The project reports +costs per period - PyPy have two periods. + +Again - the need for open and transparent communication together with a collaborative +climate created the need to have what we believe a unique view on cost reporting +within the project. In PyPy all timesheets are gathered on a monthly basis and stored in +central repository, accessible for all consortium partners (managers and developers alike). +Cost claims from all partners are gathered on a six month basis. This data helps the +management board and technical board to assess the status of work. + +Templates for timesheets, costs claims, resource tracking tools etc are created in open +formats and all data is stored under the same version control that we use for the source +code. All reports are produced with docutils/ReST format which together with automated +mailinglists for covering updates in the version control repositories allows for collaborate +peer-reviewing regarding the EU-level of reports. Again the strategy was to use the same +tools and practises on consortium level work as is used in the development process. +Interesting to note is that the technical reports written for the Commission regarding certain +deliverables and progress have also been a great help towards the community who also have +free access to these reports and view them as extra, although peculiar formated, documentation. + + Communication and documentation ------------------------------- +All documentation and supporting communication infrastructure is hosted on the same developer +server as the source code, covered by the same version control system. Only a few repositories +are not public available (such as the resource tracking repositories) - but they are fully accessible +for everyone employed by a partner organization. + +The communication infrastructure being used on the consortium level of work mirrors that of the +development work - having years of experience on the distributed workstyle. In the case of PyPY +there are mailinglists as well as IRC channels for consortium level work. We even implemented a +procedure in our internal consortium agreement to allow for virtual meetings for decisions in +the consortium. So far this have been the primary meeting form and it has worked well as a channel +for making decisions. IRC-logs and minutes support the procedure. In some cases decisions have also +been made via email on the consortium mailinglist. + +Although not the primary focus it is also useful to have the regular sprints to coordinate specific issues +between some partners or between all partners, have physical meetings and discussions between +the management team and the technical board etc. + +Our funding have also resulted in the possibility to have a more unorthodox documention - the project +have experimented in filming sprints to show the development method as well as filming talks and +discussion. Our film material is planned to be released before summer 2006. + Troubles in Paradise:striking a balance ======================================= Developer driven versus formal project structure ------------------------------------------------ +The fear of a top-down, hierarchial decision process of the consortium was a justified one. +It is interesting for us to note that now, having the experience and more contractual +overview to note that there is nothing in the requirements from the Commission that forces +a project to a more traditional and strict project process. It is mostly a question of the +experience and customs of the partner companies. In that sense there was much flexibility +in designing a process that allowed for a developer driven process regarding not only software +development but also sprint administration and planning as well as consortium work. + +The majority of the partners on key roles in the consortium organization had been working +together since before the funding, procedures and best practises had been tried out. The +results from the first year showed that a minimalistic path could be identified and that the +important work would be to review and adjust the process when it did not support the work +any more, or new situations arose that we had not planned for (and that did happen!). + +Already year two has another look-and-feel to it on a consortium level when it comes to +how the management team and the technical board works, because of the different +nature of work in year two. + Agile strategies versus formal EU-contractual requirements ---------------------------------------------------------- +Our main agile practise, sprint-driven development, was successfully integrated into +the formal contractual requirements, allowing for the same free-floating agile process +of self organizing and decision making as existed before the funding, but with a more +systematic and documented style. + +But here is also our biggest failure, the main "un-agile" aspect of the entire project having +a large negative effect not only on the EU-part of the project but also on the community. +We had planned for a process that kept an "open-door" policy that allowed us to fund +non-consortium persons from the community to attend sprints. The budget was allocated, +the procedure within the sprint context of handling more newcomers were known to us - the +main showstopper was that PyPy sprint funding did not fit within the customs and practices +of contracts for cost claims in the Commission. + +Every time we want to encourage participation and fund people to participate in sprints +and contribute the procedure now is that they have to join the consortium as a full +partner - but as a "physical person".This creates the need for a contractual amendment which +adds administrative work to the project as well as for the persons in question. A too blunt +instrument and today we still do not have a working solution to this problem. It is an +unfortunate example on how the influencing factor of F/OSS, agile practices and +EU-funding collides and creates negative impact on the project. + + F/OSS community versus hierarchies for "conceptual integrity" ------------------------------------------------------------- +There are many examples of F/OSS projects and communities that have dried out +because of the fear of the architects to allow the contributors to fully participate +and also influence features and vision of the software. In PyPy this challenge comes +twofold. Not only is there a the challenge to let the core developers keep "conceptual +integrity" while also allowing the community to influence the direction and features of +the software. There is also the consortium level of work in which the core developers +could fear to "loose" the mandate of driving the architectural and design work. And +yet another layer of risk and complexity would be if the consortium level would +"shut the door" on the community, enforcing a more closed development process. + +As in many cases - being risk aware is the first step to mitigate. Because the +project is so deeply rooted in the F/OSS Python community, with it?s specific +culture and climate, and because so many people involved in the core work +on both the development and consortium level also shared this background they +took great pains to avoid situations like this to happen. In fact, what we have realized +only some months ago is that there is another risk, already partly having effect on +the community. Because of the funding the development process is progressing much +more rapidly in PyPy than more normal F/OSS projects. The speed and the dramatically +increasing learning curve could make members more passive because they do not +have the time to follow full-time IRC discussions, postings on mailinglists and the actual +source code and increasing test suites. + +This is a challenge and it is the focus of the developer group to try to distill and package +information in order to help people to better navigate the progress. + Conclusion ========== The important question is the following (and is also part of the methodological -objective of the project): is there enough room to manage a project and Ope +objective of the project): is there enough room to manage a project and Open Source community within the plan-driven inspired methods that are required in EU-funded projects, while still working agile and distributed?

Now the RefcountingGCTransformer delays the increfs on input arguments, and keeps their reference as borrowed for as long as possible (which is for the whole function unless they are merged with other values). As a side clean-up, removed 'compute_ll_ops' (rev 22858) because I needed to do something also when annotating ll_pop_alive(), not just when specializing it. Now it's just an ExtRegistry entry.

That is what CPython does too (and there are tests for it). The problem is that then getweakrefcount returns a wrong number of weakrefs in this case, since it cannot distinguish between a weakref which is there because it is really used and a weakref which is just cached (but not referenced from anywhere else). CPython does this by looking at the refcount. I think it is more important that getweakrefcount is correct than that caching works exactly identical to CPython.

See new test in test_rpbc. This is prompted by PyPy translation crashes: introducing a memo function on the pbc of all W_Root subclasses forced them to be all in the same AttrFamily, which had terribly bad effects, as follows: a few subclasses of ast.Node are instantiated generically (by calling a variable that can be any of them). The same is true for the subclasses of PyFrame. However, the __init__ in these two parts of the hierarchy are completely different. So any common pbc attribute on all W_Root subclasses caused the __init__ to come together too => obsure crash.

The challenge has been to integrate such diverse perspectives as agile +practices being used in a distributed development style in an +Open Source project that is partly funded by the European Union. + +The PyPy project started as a grass-root effort among core developers in the +Python language community, aiming at building a Python implementation purely +built in Python. It was a language implementation project that was purely +driven from a non-profit perspective which rapidly increased in complexity when +the Open Source project applied for EU-funding. + +Today the project has over 4 years of intense activity as an Open Source +community (F/OSS, Free Open Source Software) effort and have completed a +successful first year of the EU-funded effort. In order to understand how the +PyPy project manages to strike a balance between being an F/OSS community, +while also having the core work of the project being funded by the European +Union (with all the structure and process requirements that entails) we need to +look at the influencing factors of the project process. + +The influencing factors of the PyPy project process are: +\begin{itemize} +\item {} +The F/OSS/Python community factor. Different Open Source communities have +different ``flavors'' regarding culture, communication climate, structure, +decision-process etc. PyPy was born out of the Python Community and shares +some of its characteristics which have had a huge influence on the project +process so far. Aspects such as distributed/dispersed development and the +supporting practices and infrastructure in place to quality assure software +development in a collaborated manner are part of this important influencing +factor. + +\item {} +The Agile factor. Almost a subset of the F/OSS/Python community factor - +agile practices that have been in use since the inception of the project, that +in fact have been the main drivers of the project are very much inspired by +other projects in the Python community. A key aspect of this influencing +factor is the Python version of ``sprinting''. We will present this ``agile'' +practice, explain and trace its origins within the Python community and +identify which of the main agile practices inspired the Python world to go +``sprinting'' - a key technique today not only for the PyPy project but also +for all main Python projects. We will also touch on aspects such as Test +Driven Development and explain how these are implemented in PyPy. + +\item {} +The EU factor. PyPy is the first F/OSS community that organized themselves +into an EU-project, receiving EU-funding. It has had a huge impact on the +project, and it is important to identify how EU project and process +requirements can be ``weaved'' into an Agile F/OSS project - a challenge +indeed. The EU-funding has been and still is an enormous opportunity; the +project would not have had the rapid progress and impact it is now having +without the funding. It is also very important to note that without striking +the right balance between the three main influencing factors (F/OSS, agile +and EU-funding) this factor might also prove to be a ``show stopper'', something +that might influence the PyPy community negatively. This is a constant +challenge - we explain here how we created our process and added a +``consortium-level'' structure to the F/OSS community and the steps we took in +order to mitigate this risk. + +\end{itemize} + +Our conclusion so far in the project is that we believe that the practice of +sprint-driven development, as being used in the PyPy project, makes Agile and +Distributed/dispersed work styles more possible to combine. We also believe it +is a very useful practice for creating value and ensuring quality in projects +with hybrid cultures and methodologies. It is our aim to start to show-case +this with experiences from the first funded year of PyPy. We also feel that our +experiences as a unique hybrid project would be of interest to other +communities such as the agile community and we hope that this paper will +encourage cross-community interaction and communication. + + +%___________________________________________________________________________ + +\hypertarget{project-context}{} +\subsection{Project context} + + +%___________________________________________________________________________ + +\hypertarget{objectives}{} +\subsubsection{Objectives} + +Due to the dual nature of the project even such a thing as objectives can get +complicated. If you, as a potential PyPy user, would visit out main developer +server, Codespeak, you would find the following statement: + +``The PyPy project aims at producing a flexible and fast Python implementation. +The guiding idea is to translate a Python-level description of the Python +language itself to lower level languages. Rumors have it that the secret goal +is being faster-than-C which is nonsense, isn't it? more...'' + +Codespeak housed the F/OSS project since its inception and it has been a +driving strategy to continue a look-and-feel of a purely F/OSS project in order +to not confuse developers interested in just that - PyPy as a Python +implementation. + +Digging a bit deeper you can find documentation which states the objectives of +the EU-funded part of the project. The EU project?s title is ``PyPy'' which is an +``acronym'' for ``Researching a Highly Flexible and Modular Language Platform and +Implementing it by Leveraging the Open Source Python Language and Community''. +The EU-project has three objectives: one technical, one research-oriented and +one methodology-oriented objective. In short PyPy is about building an +optimized compiler and interpreter purely in Python, applying Aspect Oriented +Programming and abstract interpretation techniques. The methodology objective +aims at showcasing the ``sprint-driven development method'' being used by PyPy +and you can view this paper as part of fulfilling the methodology objective. +For more references on sprint-driven development, please see our paper for +the XP 2006 conference \cite{key-1}. + + +%___________________________________________________________________________ + +\hypertarget{strategy}{} +\subsubsection{Strategy} + +The strategy of the project is to leverage the community of PyPy and Python +through an open and transparent communication and working style. The challenge has +been to implement this strategy, not only in the F/OSS community part of the +project, but also in the partially funded consortium structure of the project. + +The F/OSS part of PyPy has no budget tied to it and no formal organizational +structure. There are no resources tied to it other than the volunteers +participating in the development process. These are the core developers and +architects behind PyPy but also people from all over the world, driven by a +combination of professional need and personal interest in Python language +implementations such as PyPy and choosing to contribute to PyPy. There is also +a large group of students on PHD levels participating and contributing, using +their areas of interest in PyPy as thesis materials. + +It is difficult to estimate the amount of people involved in PyPy but we +estimate that 300-500 people actively follow the progress of the project - +this might mean reading emails, IRC logs and documentation in some cases, asking +questions and sending bug reports in others. There are around 50 people who +have commit-rights to the source code. The core group of developers consists of +around 10 people. + +The EU part of the project is organized through a consortium which consists of +8 partners: DFKI (Germany), Ab Strakt (Sweden), Logilab (France), merlinux GmbH +(Germany), tismerysoft GmbH (Germany), Change Maker (Sweden) , Impara GmbH +(Germany) and Heinrich Heine Universit?t D?sseldorf (Germany) and 4 physical +person partners: Laura Creighton (Sweden), Richard Emslie (UK), Eric Van Riet +Paap (Netherlands) , Niklaus Haldiman (Switzerland). + +The project effort of work for the 2 years of funding consists of 14 +work-packages and in total 58 deliverables which are high-level functional and +non-functional requirements that were formulated in a proposal and form the +``Description of Work'' in the contract with the European Commission. The funding +received for this effort is 1.3 million euro. Of the core group of developers +mentioned above almost all of them (10 people) are involved in some sense in +the partner companies and organizations of the PyPy consortium. + + +%___________________________________________________________________________ + +\hypertarget{history}{} +\subsubsection{History} + +The ideas behind PyPy started via discussions on European mailing-lists in the +Python community late 2002 by people who had been active in the Python +community for some time; core developers interested in language implementation. +They based the discussions and ideas partly on their experiences with +developing and driving some well-known projects in the Python community. They +met up in February 2003 at a ``sprint'', a one week working meeting,to draft +their ideas and to start PyPy as an Open Source project. The sprint facilities +as well as travel, accommodation and time was financed by all participants +privately. + +Mid 2003 the idea of trying to get EU-funding for the project was born. It +became clear that the project had an arbitrarily large scale and that receiving +some funding would dramatically increase the pace and seriousness of the +project - because funded developers can dedicate more of their time to the +project. The involved developers and people stretched outside of the Open +Source ecologies to try to gather as much information and contacts as possible +in order to answer the question: ``Should we go for it?'' to which the answer +quickly became ``Let's see how far we get!''. + +Acting on this strategy proved to be a more difficult task. The entire proposal +and negotiation process took over a year (Autumn 2003 until November 2004).A +proper description of planned work, necessary to satisfy formal requirements, +had not previously been part of the development focus and both the EU and the +parties involved had to adapt to the situation. + +The contract with the EU was signed and the funded part of the project, with +its consortium structure, started 1 of December 2004. The funded part of the +project ends in November 2006. + +The first funded year of the project ended with a review in Brussels in January +2006, hosted by the Commission, reviewing the 10 deliverables comprising the +work of the first year. All deliverables were accepted; based on +recommendations by the external reviewers. The consortium and the Commission is +now restructuring the volume of the remaining the deliverables (although not +changing the scope of the project). + + +%___________________________________________________________________________ + +\hypertarget{influencing-factors-the-f-oss-python-community-culture}{} +\section{Influencing factors: the F/OSS Python community culture} + + +%___________________________________________________________________________ + +\hypertarget{the-python-community}{} +\subsection{The Python community} + +Python is an Open Source language, published under an OSI approved open source +license. It was created by Guido van Rossum and is now one of the five most +used languages in the world. Due to the nature of the language there is a +strong focus on glue and integration with other languages such as C and Java. +Typical aspects of the Python community is that it houses four large +language implementations as separate projects which communicate and discuss +their experiences and approaches with each other. This intra-extra community +focus and interest has created a collaborative atmosphere with an open and +transparent communication climate. + + +%___________________________________________________________________________ + +\hypertarget{the-pypy-community}{} +\subsection{The PyPy community} + +The PyPy project is one of the four large language implementation projects in +the Python community. PyPy grew from the architectural experiences from +previous successful Python projects and this prior community experience was +vital for the evolving of the PyPy community due to the established trust in +expert skills of the core developers starting PyPy - again the people +factor. Thus making it easier recruit people into the PyPy community. + +The PyPy project inherited the focus on collaborative approaches and open +communication climate. The strategy of using sprints, as a core technique, to +kick-start the project as well as moving the sprints to different +locations had clear effects. It encouraged participation by meeting people locally. +During the period of 2003-2004 6 sprints were arranged in various European cities. +These sprints were hosted by universities and private +individuals, participation was funded privately. The effect on the evolving community +was a stable subscriber participation on the development list of between +140-150 people. After the EU-funding and the more systematic structure of +sprinting every 6th week the amount of subscribers went from around 150 people to +over 250 people. Thus turning the prior experience of separate sprints into +a more systematic approach, sprint-driven development. + + +%___________________________________________________________________________ + +\hypertarget{supporting-infrastructure}{} +\subsection{Supporting infrastructure} + +The amount of collaborative focus and open and transparent communication in an +open source community will manifest itself in the supporting infrastructure. +In PyPy version control is the primary means of providing a secure platform for +incremental development. Subversion is used, covering both +program files and documentation. Several automated mailing lists make sure +that every person involved receives instant notification on changes - +supporting peer review on all levels. + +PyPy is also in some sense very much test-driven. PyPy is one of the primary +users of a separate F/OSS project called the py.test, tools for automated +testing with PyPy developers contributing improvements to py.test. Py.test +contains a sophisticated system for running tests against the Python Standard +Library. It provides automatic selection of overriding tests in case there is +internally developed code that overrides the Python Standard Library. These are +important compliance features when the project is about language implementation. +There are also powerful mechanisms for disabling specific +tests and for producing useful traceback output. There are also automatically +generated web pages that show the status of all tests as per the latest checked +in test results. This together with a public issue-tracker covering bugs keeps the +development group focused on the quality of the code when doing +continuous integration. It greatly reduces the need +to coordinate and delegate refactoring work - this is handled in a self-organized way. + +The main communication channels between developers involved in PyPy is to +discuss over IRC (Internet-Relay-Chat) - open for all who are interested. +Several mailing lists for discussions and information are also used. Web pages, +documentation, tutorials, talks and papers etc are all available on the central +developer server for everyone to access. A very useful feature that really supports +information and communication are the public email archives covering the key +mailing lists - going back to the start of 2003. As a newcomer to the project +in the fall of 2003 these public and easily accessible mailing list archives +was the primary means for me personally to get into the project. It provided answers +to who had been key people in the process, what had been crucial topics, how had +discussions and decisions been handled. It is also regularly being used with newcomers +in the development team, providing fast answers to questions and also providing context +to technical decisions being made in the past. A useful just-in-time documentation +and a unorthodox but very efficient way of disseminating information and knowledge. + +Now - all this infrastructure is being used in almost all larger open source +projects and quite a few of them are much more hierarchical and non-transparent +in their communication. In PyPy there is no hierarchy for receiving +commit-rights. A newcomer to PyPy can instantly receive an account on the +development server, with full commit rights to the version control system. The +reason why there are no constraints is that the process is very much +self-organized and managed by the developers from a social level (peer review, +code review, supporting communication channels, coaching, mentoring) and with +strong automated tools covering tests, versions and back ups covering the +technical level. + +An extensive coding guide, published on codespeak.net (development website) +serves as an introduction to the set of specifications being used while coding +PyPy. Yet another piece of the puzzle, the coding guide together with +commit-access to both source code and tests supports cohesion in the development +process. This increases readability and uniformity so that automated testing tools can +be more efficiently used. Again - simple and useful support that is much needed when +working dispersed in a larger team of developers that might never meet face to face. + +In a distributed and dispersed work style these two (social and technical) +levels needs to be consistent and support each other. Discrepancies would be +immediately noticed. As stated before - the people factor is again evident. +If you wish to encourage participation and contribution there has to be trust as +well as a supportive environment in order to manage a virtual collaborative +workspace. The main feature of such a supportive infrastructure is to reduce +the cost of information since coordination and communication is even more difficult +in a dispersed environment. If this easily accessed information of the status of the software +is combined with trust (that is commit-rights) you have the basis for a proactive, +self-organized culture. + + +%___________________________________________________________________________ + +\hypertarget{supporting-practices}{} +\subsection{Supporting practices} + +Another good example of the collaborative nature of the Python community is the +way in which the various projects share best practices. Core developers in the +PyPy project picked up the practice of synchronization meetings as a powerful +way of supporting distributed and dispersed development. This practice was inspired +by the experiences of development processes at Canonical. + +Sync-meetings are weekly short coordination meetings between developers. These are +open to all developers active in the PyPy community, usually but not necessarily +involving aspects of EU-funded work on deliverables. These 30 minute +IRC-meetings serve a weekly synchronization for regular discussions and +integration of ongoing work. Meetings are prepared with an agenda sent out to +pypy-dev and minutes are distributed on pypy-dev and archived in the repository +with publicly accessible links. The work of preparing, managing and documenting the +meetings is rotated between active developers and is self-organized as well. + +Sync-meetings have proved to be a very good complement to a process in which +the project sprints every 6th week. Sync-meetings keep cohesion as well as a +team focus-and-feel for the dispersed work style between sprints. There are three +crucial aspects of this practice. The first one is that our experience as well as +that of Canonical points to keeping the time for the meeting brief. The reason for +30 minutes limit is that it gives priority on what topics to choose. However +complex your development situation is you should choose not more than 3 topics, +topics that could be discussed and decided upon during these 30 minutes. Not having +this time limit would create long and tiresome IRC meetings which would affect motivation +people and also create more confusion than results. + +The second aspect is that it has a fixed format in which the meeting starts with +all developers participating in the meeting presents a very short status - answering +the questions LAST (last week), NEXT (their focus for the upcoming week) +and BLOCKERS (if they are stuck and need help). This means that the group get +overview and can track progress, albeit loosely. All individuals get an opportunity to +voice their personal situation and the group jointly discuss potential blockers and how +to solve them. The fixed format help to keep focus and creates a rhythm that makes it +easier for newcomers to get into the flow of the meeting. + +The third aspect is also the main challenge with the practice. In PyPy we rotate +the organization of the meetings between the developers. But because meeting +moderation has to do with experience, people skills as well as a certain overview of +the project not everyone can actually do this task. Our experience shows that it is +also very important to have core people involved in identifying topics needing to be +discussed - having the progress of the project in mind. It is very easy to choose +topics that do not need the group mind to discuss, that are too detailed, that has +too much focus on information distribution rather than discussions. + +Here is what one of the new core developers of PyPy says about sync-meetings: +\begin{quote} + +\emph{``Sync-meetings are useful because they enable developers to discuss and +clarify issues among themselves and to provide a common focus when working +distributedly. They are also a lightweight way to synchronize activities, +resolve blockers and to get an overview about who is currently doing what +work.''} +-- Carl Friedrich Bolz +\end{quote} + + +%___________________________________________________________________________ + +\hypertarget{influencing-factors-agile-practices-in-pypy}{} +\section{Influencing factors: agile practices in PyPy} + + +%___________________________________________________________________________ + +\hypertarget{sprints}{} +\subsection{Sprints} + +PyPy first started during a one-week meeting, a ``sprint'', held at Trillke-Gut +in Hildesheim February 2003. The sprint was inspired by practices used by other +Python projects such as Zope3. Originally the sprint methodology used in the +Python community grew from practices applied by the Zope Corporation. Their +definition of a sprint was: ``two-day or three-day focused development session, +in which developers pair off together in a room and focus on building a +particular subsystem''. + +Tres Seaver of the Zope Community, one of the instigators of the sprint +method as it is used in the Python community says the following about how they +evolved the method during 2001 and 2002: +\begin{quote} + +\emph{``The motivation was to begin using as much of XP as would fit to +accelerate Zope3 development. Given the different development culture of +the Zope community (framework-centric, distributed, no ''business user`` +present), some of the XP mantras /practices couldn't be done directly. We +decided to try to do ''as much XP as possible`` for short, highly-focused +sessions, with all active committers collocated.''} +\end{quote} + +The Zope community as well as other Python projects such as PyPy have seen that +sprints generate results beyond the creation of software: +\begin{itemize} +\item {} +It helped to evolve the community through participation and hands-on contact +with the core developers. + +\item {} +It is a live training session not only in producing code but also in the +development methods being used (the sprint method in itself, pair programming +and TDD). + +\item {} +It supports activities such as design decisions and high-level requirements +discussions, creating cohesion and understanding as well as minimizing risks +with dispersed/distributed work where these kind of activities can be really +difficult to manage. + +\end{itemize} + +In order to provide examples - in PyPy these discussion sessions have been done in +various different ways during sprints. The proposal for the EU and the work package +descriptions were drafted through group discussions during sprints. Later sprints in which +the process needed design decisions, developers paired up in several groups of 2-4 +people per group for daily discussion sessions. These sessions ended with brief +documentation and presentations for the other groups where decisions were made. +Usually what happens is that the daily sprint planning results in a pair of core developers +choosing a topic to discuss. These discussions have even acted as tutorials for other +developers sitting in and following the discussions. Some of these discussions have also +been filmed for dissemination purposes. + +The reason for naming the method sprinting, is not at all connected to Scrum and +the usage of sprints in that context, according to Tres Seaver is: +\begin{quote} + +\emph{``... because of the fact that we weren't doing XP in its proper sense, +which is more like running a long-distance race, where pacing oneself is +critical. Instead, we were pushing as fast as possible in order to +maximize the benefit of limited face time. Of all the XP practices, the +one we gave shortest shrift to is ''no overtime``: as sprints often go far +into the evening (or even the wee hours of the morning.''} +\end{quote} + +To summarize the results of this first try out of the methodology shows that +sprinting was the driver for making Zope3 a community-driven project: Zope +Corporation in fact ceded control over the development process to the new +``Zope3 core'' group created via sprinting. Less than 2 years later the same effect +was to be found in the F/OSS project PyPy - the community evolved through +sprint driven development. + +The sprint method, as well as key aspects of F/OSS supportive infrastructure +and practices was established within the project before PyPy received its +EU-funding. Thus, in the proposal,we put much emphasis on the methodology in +itself when designing the consortium level process. Examples of how this was +done was that we created a methodology objective, specific deliverables +regarding documentation of the sprint-driven methodology as well as designing a +process during the 2 years of funding in which the project and the developers +sprints every 6th week. This was taken into account when estimating the budget, +adding costs for travel and accommodation for all partner organizations - +covering 14 sprints during the 2 years. So far during the funded part of the +project we have organized 10 sprints - successful sprints from both a +development, recruiting, dissemination and networking aspects. Another +important fact is that the sprints are organized by the developers and as such +is another good example of the collaborative manner of the culture of the +project and the community. + +Why did PyPy choose sprinting as a key technique? It is a method that fits +distributed teams well because it gets the team focused around visible +challenging goals while working collaboratively (pair-programming, status +meetings, discussions etc) as well as accelerated (short increments and tasks, +``doing'' and testing instead of long startups of planning and requirement +gathering, continuous integration). This means that most of the time a sprint +is a great way of getting results and getting new people acquainted - a good +method for dissemination of knowledge and learning within the team. + +Another insight, worthwhile for other more discipline based projects to ponder, +is how an agile process like sprinting is much more suited for creative work +between groups of distributed people. Traditional software development, as well +as traditional project management techniques have a tendency to hinder creativity +due to the inbuilt over-structured, segmented and control-oriented approach +which in most cases ends in less quality when results are being measured. + + +%___________________________________________________________________________ + +\hypertarget{eu-project-practices}{} +\section{EU-project practices} + + +%___________________________________________________________________________ + +\hypertarget{consortium-structure}{} +\subsection{Consortium structure} + +Key requirements regarding organizational structures of a Framework Programme +6 EU-project are: +\begin{itemize} +\item {} +a consortium of partners performing the work described in the contract + +\item {} +a project co-coordinator managing contract administration and communication +between consortium and the Commission + +\item {} +a project manager, responsible for the project reaching its goals within the +time frame and budget + +\end{itemize} + +The challenge was to design a project process that created a minimal amount of +changes to the structure being in use in the F/OSS project. It was especially +important to maintain an open and transparent communication, even for decision +on consortium level and such. There was a fear of the EU-project adding +``top-down'' structures on the F/OSS work and on the core developers instigating +the project. + +We identified a minimalistic approach of management roles (project +co-coordinator, project manager, assistant project manager) and created a +management team to make sure that there was collaboration between these roles. +Although the responsibility rested on the different management roles and the +management team the strategy implemented was to delegate as much as possible of +the responsibilities and decision-making to the core developers. + +The strategy was to keep ``conceptual integrity'' \cite{key-2} of +the vision and the idea in the hands of the core developers. As Brooks +stresses, a uniform system design is better than uncoordinated and independent +design ideas. The core developers had a clear and agreed vision - but would +they be allowed to implement it within a fixed contract work style, with new +partners involved that had not been involved in the process from the start? The +core developers were organized into a technical board, responsible for planning +and coordinating the development work between the partners, with the mandate to +make decisions. A somewhat negative result was the added workload and +responsibility on developers regarding EU related work. + +This structure was the most difficult to design and implement due to the very +different nature of its purpose compared to the collaborative, self-organized +nature of the F/OSS project - again it succeeded the way it has because of the +core developers acting as an interface between the developer group and the +consortium level work - again we see the trust aspect and the people factor in +play. + +Sprints were budgeted for and designed into the process, together with a +time plan for all deliverables. The project was divided into three different +phases, depending on the nature of the work flow. In that sense we could +describe the EU-part of the project as a fixed-contract style of work, but with +time plan, deliverables and work package descriptions on a high-level, not +broken down into more granular tasks. + + +%___________________________________________________________________________ + +\hypertarget{communication-and-documentation}{} +\subsection{Communication and documentation} + +All documentation and supporting communication infrastructure is hosted on the +same developer server as the source code, covered by the same version control +system. Only a few repositories are not publically available (such as the resource +tracking repositories) - but they are fully accessible for everyone employed by +a partner organization. + +The communication infrastructure being used on the consortium level of work +mirrors that of the development work - having years of experience on the +distributed work style. In the case of PyPY there are mailing lists as well as +IRC channels for consortium level work. We even implemented a procedure in our +internal consortium agreement to allow for virtual meetings for decisions in +the consortium. So far this have been the primary meeting form and it has +worked well as a channel for making decisions. IRC-logs and minutes support the +procedure. In some cases decisions have also been made via email on the +consortium mailing list. + +Although not the primary focus it is also useful to have the regular sprints to +coordinate specific issues between some partners or between all partners, have +physical meetings and discussions between the management team and the technical +board etc. + +Our funding have also resulted in the possibility to have a more unorthodox approach +to documentation - the project have experimented in filming sprints to show the +development method as well as filming talks and discussion. Our film material +is planned to be released before summer 2006. + + +%___________________________________________________________________________ + +\hypertarget{troubles-in-paradise-striking-a-balance}{} +\section{Troubles in Paradise: striking a balance} + + +%___________________________________________________________________________ + +\hypertarget{developer-driven-versus-formal-project-structure}{} +\subsection{Developer driven versus formal project structure} + +The fear of a top-down, hierarchical decision process of the consortium was a +justified one. It is interesting for us to note that now, having the +experience and more contractual overview to note that there is nothing in the +requirements from the Commission that forces a project to a more traditional +and strict project process. It is mostly a question of the experience and +customs of the partner companies. In that sense there was much flexibility in +designing a process that allowed for a developer driven process regarding not +only software development but also sprint administration and planning as well +as consortium work. + +The majority of the partners with key roles in the consortium organization had +been working together since before the funding. In that sense procedures and best +practices had been tried out. The results from the first year showed that a minimalistic +path could be identified and that the important work would be to review and +adjust the process when it did not support the work any more, or new situations +arose that we had not planned for (and that did happen!). + +Already year two has another look-and-feel to it on a consortium level when it +comes to how the management team and the technical board works, because of the +different nature of work in year two. + + +%___________________________________________________________________________ + +\hypertarget{agile-strategies-versus-formal-eu-contractual-requirements}{} +\subsection{Agile strategies versus formal EU-contractual requirements} + +Our main agile practice, sprint-driven development, was successfully integrated +into the formal contractual requirements, allowing for the same free-floating +agile process of self organizing and decision making as existed before the +funding, but with a more systematic and documented style. + +But here is also our biggest failure, the main ``un-agile'' aspect of the entire +project having a large negative effect not only on the EU-part of the project +but also on the community. We had planned for a process that kept an +``open-door'' policy that allowed us to fund non-consortium persons from the +community to attend sprints. The budget was allocated, the procedure within the +sprint context of handling more newcomers were known to us - the main +show stopper was that the PyPy sprint funding did not fit within the customs and +practices of contracts for cost claims in the Commission. + +Every time we want to encourage participation and fund non-consortium +people to participate in sprints and contribute, the procedure now is that +they have to join the consortium as a full partner. +This creates the need for a contractual amendment with the Commission which +adds administrative work to the project as well as for the persons in question. +A too blunt instrument and today we still do not have a working solution to this +problem. It is an unfortunate example on how the influencing factor of F/OSS, +agile practices and EU-funding collides and creates negative impact on the project. + + +%___________________________________________________________________________ + +\hypertarget{f-oss-community-versus-hierarchies-for-conceptual-integrity}{} +\subsection{F/OSS community versus hierarchies for ``conceptual integrity''} + +There are many examples of F/OSS projects and communities that have dried out +because of the fear of the architects to allow the contributors to fully +participate and also influence features and visions of the software. In PyPy +this challenge comes twofold. Not only is there a challenge to let the core +developers keep ``conceptual integrity'' while also allowing the community to +influence the direction and features of the software. There is also the +consortium level of work in which the core developers could fear to ``lose'' the +mandate of driving the architectural and design work. And yet another layer of +risk and complexity would be if the consortium level would ``shut the door'' on +the community, enforcing a more closed development process. + +As in many cases - being risk aware is the first step to mitigation. Because the +project is so deeply rooted in the F/OSS Python community, with its specific +culture and climate, and because so many people involved in the core work on +both the development and consortium level also shared this background they took +great pains to avoid situations like this to happen. In fact, what we have +realized only some months ago is that there is another risk, already partly +having effect on the community. Because of the funding the development process +is progressing much more rapidly in PyPy than more normal F/OSS projects. The +speed and the dramatically increasing learning curve could make members more +passive because they do not have the time to follow full-time IRC discussions, +postings on mailing lists and the actual source code and increasing test suites. + +This is a challenge and it is the focus of the developer group to try to +distill and package information in order to help people to better navigate the +progress. + + +%___________________________________________________________________________ + +\hypertarget{conclusion}{} +\section{Conclusion} + +The important question is the following (and is also part of the methodological +objective of the project): is there enough room to manage a project and Open +Source community within the plan-driven inspired methods that are required in +EU-funded projects, while still working agile and distributed? + +We believe so. The one clear dominating factor to make all this succeed is, as +always, the people factor, the CRACK performers as Boehm and Turner calls them +(``Collaborative, Representative, Authorized, Committed, Knowledgeable'') +\cite{key-3}. + +The core developers of the PyPy project had the right mix of various skills in +order to succeed in setting up a hybrid environment - enabling them to work +full time on a project they strongly believed in. The most crucial mix of +skills for making this possible was/are: +\begin{itemize} +\item {} +\textbf{Social:} The ability to communicate open and transparent, to mentor and +tutor dispersed as well as reinventing different collaborative work styles of +the sprint method, ``manage'' groups and community as well as consortium, and +handle conflicts) + +\item {} +\textbf{Leadership abilities:} The ability to step into formal leadership roles in +technical board structures, manage sprints and sync-meetings as well as the +more informal management of the community of developers. Managing the balance +between encouraging participation but still holding true to their vision, +their ``conceptual integrity''. + +\item {} +\textbf{Ability to network:} To be open to other communities, inviting new +partners in order to create a working consortium structure in the EU-project, +curious and collaborative towards other Python implementations and other +languages and research approaches, sharing knowledge and experiences and +seeking bets practices of other projects. + +\item {} +\textbf{Entrepreneurs:} To risk the community through pursuing the idea of +EU-funding in order to fulfill the ambitious vision, managing to not only +create a consortium with innovative structures of cooperation but also to +create new companies. + +\item {} +\textbf{Technical skills:} Programming language and implementation +aspects,frameworks, mathematics, computer science - core skills for the +project. Also the ability to design, setup and effectively manage supporting +infrastructure for the development process. + +\item {} +Managing the balance between encouraging participation but still holding true +to their vision, their ``\textbf{conceptual integrity}'' This while working agile with +open and transparent communication through sprints, documentation, tutorials, +mentoring, sync-meetings. Resulting in a lively and growing the F/OSS +community around the project. + +\end{itemize} + +So, could it be said that for an agile software development process, especially +one that is distributed and community oriented, within a framework of +EU-funding, that it is heavily people dependent? Or to stress it even further, +sprint-driven development as a methodology does not exist and function without +an agile group of people, Crack performers. The people are the methodology in +some sense and if you wish to draw upon the experience of the PyPy team you +need to look at the supporting practices around the people in order to find +what can be duplicated and tested in another project environment. This +conclusion matches what Alistair Cockburn writes in his paper ``Characterizing +People as Non-Linear, First-Order Components in Software Development'' +\cite{key-4}: +\begin{quote} + +\emph{``The fundamental characteristics of ''people`` have a first-order +effect on software development, not a lower-order effect.''} +\end{quote} + +If we accept this conclusion then we can also, thanks to the people, start to +get innovative regarding practices. Designing the project process based on the +specific needs of the unique project environment you are facing. In the case of +PyPy this means that we are exploring the methodology as we go along, adjusting +and fine tuning the process as well as the software. + +So, when drawing from these different skills within the community of +developers, the people, in the PyPy project one possible conclusion would be +that a truly agile approach dominating the work style of an Open Source project +will increase the ability of the community to spread the strategy of agility to +other domains. + +By this we mean that what started as agile practices in the development process +quickly became influencing factors when designing other project processes. +Examples of this in PyPy is how the sprint-driven development acts as a focal +point not just for the development work (co-located as well as dispersed) but +also for the formal and informal management of the project. Sprints together +with the CRACK performers was what made the community grow and evolve. It was +the foundation for a hybrid project where agile practices and EU-funding can +fit within a distributed Open Source context. + + +%___________________________________________________________________________ + +\hypertarget{acknowledgments}{} +\section{Acknowledgments} + +The author would like to thank the following people who have in various ways +helped with the creation of this paper: Angela Martin, Emily Bache, Tres +Seaver, Carl Friedrich Bolz. + +I would like to dedicate this paper to my dear friend and mentor of the Open +Source Python and PyPy community Holger Krekel. +% References: +% =========== +\begin{thebibliography}{1} + + \bibitem{key-1} Beatrice D?ring, "Sprint-Driven Development: Agile methodologies + in a Distributed Open Source Project (PyPy)", XP 2006 + +\bibitem{key-2} Fredrick P.

Log:
rstr has been refactored: most code belonging to lltypesystem has been
moved from rpython/rstr.py to rpython/lltypesystem/rstr.py.

The low level helpers are collected togheter as staticmethods of the
LLHelpers class. lltypesystem.StringRepr has an 'll' attribute that
contains that class : this way AbstractStringRepr & Co. can reference
them without the needing of a separate StringRepr attribute for each
helper, as happens in rlist.py.

Modified:

   pypy/dist/pypy/translator/goal/targetpypystandalone.py
Log:
So far, multimethod.py uses the InstallerVersion1 by default
because it is much faster both to initialize and run on top of CPython.
The InstallerVersion2 is optimized for making a translator-friendly
structure.  So we patch it in-place from targetpypystandalone...
That's temporary, hopefully.

Log:
Completed refactoring of rstr:

  - added AbstractCharRepr and AbstractUniCharRepr to rstr
  - AbstractStringRepr has moved from rmodel to rstr
  - got distinct CharRepr and UniCharRepr for the two typesystems
  - removed any dangling reference to lltypesystem from rpython/rstr.py
  - fixed some modules referencing things that have been moved

Now code in rpython/rstr.py should be completely indipended of
typesystem, so we can start working on ootypestem/rstr.py

+=====================================================
+
+attendants: michael, anto, samuele, christian, richard, 
+            eric, arre, armin, holger (mods and minutes) 
+
+* activity reports: everybody posted, see log below. 
+
+* thread cloning approach 
+
+  As discussed earlier it is urgent to have a working 
+  thread cloning approach.  Armin posted his suggestion 
+  to pypy-dev which builds on the Leysin and other 
+  previous works.  He thinks it will take at least 
+  2 weeks solid work and that it involves experimentation 
+  at some levels so it's hard to predict things exactly. 
+  Christian agrees to this approach.  Armin will start on this
+  and he will also try to get early feedback from Aurelien and Nicolas. 
+  Implementation wise Michael and a bit of Holger will try
+  to help. 
+
+  Moreover Christian is to describe and finalise a different
+  approach for the larger topic of "thread pickling" at the
+  early June sprint.  Holger reminds that EU-wise we promised
+  the whole of Work Package 7 to be complete and having a
+  report in June and that we should get clarity about 
+  according plans. 
+  
+* Next PyPy sprint: 2nd-9th june, Duesseldorf 
+
+  It seems that Armin, Michael, Samuele, Holger, Christian, Carl, 
+  Arre, Eric (partly), Anto and possibly others can make it 
+  to the next PyPy sprint from 
+  
+        2nd-9th June 2006
+
+  It is almost set that we are going for Duesseldorf (germany) 
+  as a location.  Michael to prepare an announcement until 
+  saturday with review from Holger (and others).  Carl to 
+  continue to fix a location.  
+  
+  Topics will be the 0.9 release, ext-compiler, stackless and
+  more or less all topics that have been floating lately.

+May 11 17:05:04 	ok, pedronis? 
+May 11 17:05:21 	LAST: worked on gc issues and stackless transform with Armin, worked on rctypes stuff with arre, various non-coding stuff
+May 11 17:05:23 	NEXT: will see, we need to work on the OOPSLA paper too
+May 11 17:05:24 	BLOCKERS: too much stuff
+May 11 17:05:43 	ok, thanks 
+May 11 17:05:47 	then let's talk about thread cloning 
+May 11 17:05:54 	i guess everybody is aware of armin's posting to pypy-dev 
+May 11 17:06:12 	yes, and I'd like to sign it
+May 11 17:06:58 	you mean that you agree to armin tackling the tasks regarding thread cloning as described? 
+May 11 17:07:34 	it is pretty much what we descussed, yes
+May 11 17:07:38 	good
+May 11 17:07:47 	but I've read the logic design paper, and I'm no longer convinced that this is what they need.
+May 11 17:07:47 	then there is the still somewhat open part regarding thread pickling
+May 11 17:07:50 -->	stedi67 (n=stedi67 at p54BCF4CA.dip.t-dialin.net) has joined #pypy-sync
+May 11 17:07:54 stakkars stedi67 May 11 17:07:57 	stedi67: hi stephan 
+May 11 17:08:04 	hi, sorry, I'm a bit late...
+May 11 17:08:15 	stedi67: we are in thread cloning, but post your activity lines if you like 
+May 11 17:08:22 stakkars stedi67 May 11 17:08:24 	thread pickling is in the works. I need to talk to Samuele and carry on
+May 11 17:08:33 	stakkars: can you commit to some time frame? 
+May 11 17:09:18 	arigo: could you grab 'auc' one day and see if the thread cloning approach and it's APIs would really help them? (i think we should make sure) 
+May 11 17:09:32 	yes
+May 11 17:09:57 	LAST: set type
+May 11 17:09:57 	NEXT: stackless, greenlet python module (app level)
+May 11 17:09:57 	BLOCKERS: None
+May 11 17:10:09 	arigo: or maybe forward the pypy-dev mail with some extra explanation to Aurelien and Nicolas to be sure 
+May 11 17:10:21 	I can't speak for eric but I think the problematic part is on my side
+May 11 17:10:28 	hpk: ok
+May 11 17:10:55 stakkars stedi67 May 11 17:11:17 	I would love to get basic things working next week, but it is safer to envision "during the sprint" in June
+May 11 17:11:33 	stakkars, I'm sure your part is harder but I must admit I'm struggling too because it involves a lot of PyPy that I am unfamiliar with. I would like a piece of Samuele too :) (preferably his brain)
+May 11 17:12:21 	ericvrp: we can talk about this, and I've been through very miuch during my stay, probably I can play a bit of Samuele
+May 11 17:12:47 	(saying that I'm very much available now)
+May 11 17:12:49 	FYI: I'm thinking of takign a vacation the week of the iceland sprint
+May 11 17:13:12 	stakkars, okay , good to know. Be prepared for a load of questions tomorrow!
+May 11 17:13:13 	good idea. in Iceland? :-D
+May 11 17:13:24 	no, I said vacation
+May 11 17:13:28 	:)
+May 11 17:13:33 	well, wild landscapes etc.
+May 11 17:14:00 	stakkars: but it means that you will work on having it finalized during the DDorf sprint then, right? 
+May 11 17:14:07 	thread pickling i mean 
+May 11 17:14:09 	kind of sort more at home likely
+May 11 17:14:22 	pedronis: sure, I know (just kidding)
+May 11 17:14:50 	this is the plan, but I don't know how realistic it is
+May 11 17:15:10 -->	rxe (n=rxe at 66.151.59.5) has joined #pypy-sync
+May 11 17:15:17 	Hi!
+May 11 17:15:25 	hi!
+May 11 17:15:32 	stakkars: sidenote: we need to determine the status of WP07 and whether you can majorly care for the an EU report finalization in June (which is promised to the EU currently) 
+May 11 17:15:33 	wahaaa
+May 11 17:15:38 	Thought I show face for a change! ;-)
+May 11 17:15:42 	rxe: hi richard :) 
+May 11 17:15:46 	rxe: hehe
+May 11 17:15:52 stakkars stedi67 May 11 17:15:53 	hi rxe
+May 11 17:16:03 	hee richard! welcome
+May 11 17:16:10 	hpk: understood
+May 11 17:16:13 	stakkars: it's not impossible to consider shifting it, but it also relates to the overall project situation and we need to get clarity 
+May 11 17:16:17 	rxe: any three liners?...
+May 11 17:16:51 	BLOCKERS: no time ;-)
+May 11 17:16:53 	ok, then for now, i think we have enough clarity mostly 
+May 11 17:17:03 	and i'd like to move on to the "next sprint" topic
+May 11 17:17:09 	rxe: ah, no, we all posted that already :-)
+May 11 17:17:16 	:-)
+May 11 17:17:35 	as you read there is the suggestion for 2nd-9th june in DDorf 
+May 11 17:17:42 *	arigo agrees
+May 11 17:18:08 	antocuni, ericvrp, arre, rxe, stedi67: i think you are the ones who didn't participate in this suggestion so far 
+May 11 17:18:16 	do you know already if you can likely make it? 
+May 11 17:18:32 	I don't know yet
+May 11 17:18:38 	It will work for me.
+May 11 17:18:39 	rxe: very unlikely:-(
+May 11 17:18:46 	but I hope yes
+May 11 17:18:56 	Maybe for a very short while, (it's ony 1.5 hours from my hometown by train)
+May 11 17:18:56 	i also know from Maciej (the JS SOC guy) that he will likely be able to come 
+May 11 17:19:13 	hpk, that's why I would at least like to meet hime
+May 11 17:19:29 	antocuni: i really hope so as well!  if you need support for travel costs or so, mention it to us (e.g. me) or so 
+May 11 17:19:53 	ericvrp: yes, you should try to make sure to both appear at the same time if you do 
+May 11 17:20:08 	what a good idea :)
+May 11 17:20:08 	but also, we will have a number of release and some other critical tasks 
+May 11 17:20:11 	obvious
+May 11 17:20:20 	I was wondering how much does it costs by train
+May 11 17:20:23 	ericvrp: yes, brilliant idea, isn't it? :)

Log:
More work on ootype.String:

  - String has been made a subclass of BuiltinADTType instead of
    OOType, so it can be treated as List and Dict; String will have a
    set of _METHODS corresponding to those of the RPythonic str;
    methods' name will start with 'll_' (e.g., ll_join instead of
    join);

  - _string is no longer a subclass of str; when an attribute whose
    name starts with 'll_' is accesed _string string delegates the
    implementation to its member '_str', thus avoiding writing a lot
    of boilerplate.

  - rstr.StringRepr has been enhanced; a test for ootypesystem has
    been written in test/test_rstr.py.

Subject: [pypy-svn] r27139 - in pypy/dist/pypy/rpython: . lltypesystem
	ootypesystem test
Message-ID: <20060512150103.A133B100B4@code0.codespeak.net>

Author: antocuni

Log:
More work on rstr:

  - Added support for null strings in ootypesystem
  
  - Part of LLHelpers has been factored out and placed in
    AbstractLLHelpers so that can be shared by the two typesystems

  - Added support for stritem, strlen, strconcat to ootypesystem

  - Some tests have been made typesystem-aware.

Modified:

Log:
A '[default]' trying to be too clever, and showing on the --stackless
option.  Changed the condition to the obvious but possibly naive one.
The current translate.py at least doesn't show another case where
'[default]' should appear but no longer does because of this change.

Log:
* Clean-up of stackless transform; split code.py in two files;
  build compressed tables instead of having multiple fields in each
  frame header; use -1 instead of 0 as the non-resuming case so that
  the table entries computation can be 0-based

* Added a .clone method() on the RPython frame types, not implemented 
  yet.

* Replaced all abuses of "bookkeeper.getdesc(func).cachedgraph(None)"
  in the PyPy sources with a new method .getuniquegraph(), which asserts
  that there is exactly one graph and returns it, no matter under what
  key.  Indeed, cachedgraph() could also build and return a fresh graph,
  with was utterly confusing the later stages of the translation 
  process.

New Revision: 27157

Added:
   pypy/dist/pypy/translator/stackless/test/test_clone.py   (contents, props changed)
Modified:
   pypy/dist/pypy/annotation/annrpython.py
   pypy/dist/pypy/rpython/rtyper.py
   pypy/dist/pypy/translator/stackless/code.py
   pypy/dist/pypy/translator/stackless/frame.py
   pypy/dist/pypy/translator/stackless/transform.py
   pypy/dist/pypy/translator/unsimplify.py
Log:
(pedronis, arigo)
The first, naive and simple test_clone.  As expected, the hard part is to
get it right with respect to the annotator and the rtyper and mixlevelhelpers.
This means a bug fix in copyvar() (!) and Yet Another Dict on the annotator.

Subject: [pypy-svn] r27158 - pypy/dist/pypy/translator/stackless
Message-ID: <20060512221859.47E2A100B4@code0.codespeak.net>

Author: arigo
Date: Sat May 13 00:18:58 2006
New Revision: 27158

Modified:
   pypy/dist/pypy/translator/stackless/frame.py
   pypy/dist/pypy/translator/stackless/transform.py
Log:
Order issues: discover new graphs and frame types for the stackless
helpers along the way during the stackless transformation.
(Apart from the few prebuilt ones, the RestartInfo instances
are now very short-lived, which makes them a bit strange).

+Duesseldorf internal-ish sprint 2-9 June 2006
+====================================================
+
+The next PyPy sprint will be held in the Computer Science department of
+Heinrich-Heine Universitaet Duesseldorf from the 2nd to the 9th of June.
+
+The main focus of the sprint will be on the goals of the upcoming June 0.9
+release:
+
+* The extension module compiler.  The goal is to be able to use a single
+  RPython source code as an extension module for both PyPy and CPython.
+  The means to get there is -- most likely -- by compiling ctypes-based
+  modules into either pypy-c or a CPython dll/so.
+
+* Write some more modules in this style with ctypes.
+
+* Stackless: the big missing feature is pickling running tasklets.
+  There is also some smaller work that needs to be done, like exposing
+  all the existing RPython-level interfaces to app-level
+  (e.g. greenlets).
+
+* Write more documentation.
+
+* Misc topics, depending on interests: back-ends (CLI, Squeak), testing
+  framework, modified semantics (security/sandboxing...), etc.
+
+
+.. _`pypy-sprint mailing list`: http://codespeak.net/mailman/listinfo/pypy-sprint

Log:
(pedronis, arigo)
General progress towards stackless_gc.  Introduced malloc(flavor='gc_nocollect')
that doesn't trigger a collect.

Worth to note: genc now makes a Makefile with a 'debug:' entry, which
cleans up and recompiles in debug mode.

Log:
(pedronis, arigo)
* started a test for the gctransformer on top of the llinterp.
* regrouped the numerous s_list_of_strings into listdef.
* added an interface in genc to prepare the database and the
    graphs without actually emitting source.
* clean-up in node about 'isgchelper', which is a name that
    used to be possibly confused for the name of a field in a
    GcStruct (!).

Modified:

   pypy/dist/pypy/translator/stackless/transform.py
Log:
convert a few stackless tests to say "rstack.stack_unwind" instead of "raise
code.UnwindException" which lets me simplify the detection of a function that
might unwind the stack.

Message-ID: <20060515154832.96832100A4@code0.codespeak.net>

Author: pedronis

New Revision: 27241

Added:
   pypy/dist/pypy/rpython/memory/test/test_transformed_gc.py
      - copied, changed from r27234, pypy/dist/pypy/rpython/memory/test/test_gc.py
Modified:
   pypy/dist/pypy/rpython/memory/gc.py
   pypy/dist/pypy/rpython/memory/gctransform.py
   pypy/dist/pypy/rpython/memory/lltypelayout.py
Log:
start of refactoring to allow gcs to be tested through the transformer on top of llinterp. Collection
still is crashing because of misconstructed fakeaddresses.

half-way to making it easier to swap in gcs when using the Framework policy and transformer.

fix in lltypelayout.sizeof

added statics functionality support at least in mark-and-sweep gc.

 It should be simple and straightforward to redo these implementations.
 Nevertheless there is a complication. The most natural way to support

+This is ok for extension types like coroutines/tasklets which we can
+control, but it should be avoided for existing types.
+
+Consider for instance frames. We would have to add a __getstate__
+and a __setstate__ method, which is an interface change. Furthermore,
+we would need to support creation of frames by calling the
+frame type, which is not really intended.
+
+For other types with are already callable, things get more complicated
+because we need to make sure that creating new instances does
+not interfere with existing ways to call the type.
+
+Directly adding a pickling interface to existing types is quite
+likely to produce overlaps in the calling interface. This happened
+for instance, when the module type became callable, and the signature
+was different from what Stackless added before.
+
+For Stackless,
 I used the copyreg module, instead, and created special surrogate
 objects as placeholders, which replace the type of the object
 after unpickling with the right type pointer. For details, see
 the prickelpit.c file in the Stackless distribution.
 
+As a conclusion, pickling of tasklets is an addition to Stackless,
+but not meand to be an extension to Python. The need to support
+pickling of certain objects should not change the interface.
+It is better to decouple this and to use surrogate types for
+pickling which cannot collide with future additions to Python.

Fixes for long-standing failures in objspace/constraint:

* don't 'import pypy' at app-level!  It's not supposed to be
  importable like this, and it's not in the app-level path
  unless put there with a PYTHONPATH env var.

* skip a test that consistently fail.  For all I can tell it
  might be testing an implementation detail that changed.

add a weakgcaddress primitive and casts to and from pointers.  and associated

the purpose of this is to have a type that will be edited as necessary by a

Log:
Stackless GC tests now passing!  Both on llinterp and in translated C.

* introduced a generic GCREF opaque pointer type for things like
    the return value of the malloc() functions

* display more information during a collect

+Translating the flow graph to Javascript code
++++++++++++++++++++++++++++++++++++++++++++++
+
+The Javascript backend is still experimental but will be worked on during this
+years `Google summer of code`_. It contains some rudimentary support for
+stackless features and a good integration with PyPy's unittesting framework.
+Code can be tested with the `Spidermonkey`_ commandline javascript interpreter
+in addition to a multitude of javascript capable browsers. 
+The emphasis of the Javascript backend is to compile RPython code into
+javascript snippets that can be used in a range of browsers. The goal is
+to make it more and more capable to produce full featured web applications.
+Please see the pypy/translator/js/test directory for example unittests.
+
+Here is a simple example to try::
+
+   >>> t = Translation(snippet.my_gcd)
+   >>> a = t.annotate([int, int])
+   >>> t.rtype()
+   >>> t.source_js()
+
 A slightly larger example

Log:
(arigo, some pedronis)

* added GCHeaderBuilder that contains the mappings between GcStructs
  and their GC headers.  In this way the mapping is not global but
  specific to the currently compiled GC.

* some fixes in the annotator to still propagate the constantness of
  Symbolics, without trying to constant-fold operations on them.

* general niceifications

Log:
Dusting of genllvm:
    * sharing exceptiontransform with genc
    * using raisingop2direct_call transformation for tests
    * some misc. fixes
    * rewrote some tests because tests that raise exceptions
      currently do not work with the exceptiontransform
    * increased the llvm minimal required version to 1.7
    * wrote a better test for the ringbuffer that hold exceptions

Added:
   pypy/dist/pypy/rpython/test/tool.py   (contents, props changed)
Modified:
   pypy/dist/pypy/rpython/test/test_rlist.py
   pypy/dist/pypy/rpython/test/test_rrange.py
   pypy/dist/pypy/rpython/test/test_rstr.py
   pypy/dist/pypy/rpython/test/test_rtuple.py
Log:
Added the module tool.py that contains some utility for writing tests
to be runned against both typesystem. Refactored tests for rrange,
rstr, rlist and rtuple for taking advantage of the new module.

fix bug in weakrefs (thanks armin). hard to write a test for it :-(. you could
see the problem by looking at the output, but since the test passes it is not
shown by default.

For the StacklessGcFramework, replace mallocs by calls to the
function, and immediately inline that, as soon as possible,
before the stackless transformer does anything.  See comments.

Log:
ah ah. too funny.

started working on making the semispace gc tested with the transformer. tried to use test_gc to see
if I broke something. there were some perplexing problems, discovered that the maze of setup and teardown
in test_gc made it so that mark and sweep was not tested by it at all anymore and it shared some
of the tweaked semispace problems. ah ah, that's why no prints.
of course mark and sweep was broken in test_gc: gcwrapper trying to annotate the __init__ which is not rpython
anymore, to shallow typos, to the os.write and strings requiring in theory that the gc function graphs
be converted too.

after quite a bit of pushing and pulling test_gc is testing successfully mark and sweep again. 
Of course accumulated more reasons for wanting to kill it and gcwrapper.

ah ah. too funny. not much progress on the semispace transformer testing tough :(

Log:
! ll_str cannot simply be removed from Reprs.

it is used by % formatting and other ll_strs. In those
cases thee one for floats was now used causing various tests
to break (even under translator/c in quite unexpected ways).

attach the rtyper to the low-level annotation policy during rtyping
and introduce a specialisation that can pick out of modules under xxtypesystem
a function based on which type system is in use:

specialize:ts('.')

use it for IntegerRepr.ll_str .

Log:
* Fixed and enabled genllvm's performance that used a ringbuffer for some
  exception mallocs. For this I moved some code back from python to C
  because I had to call the regular pypy_malloc (which is in C) when the
  size of the (to be allocated) data would not fit into a ringbuffer entry.
* Refactored codewriter a little to allow the code in jit/codegen/llvm to
  use it without the internal linkage type

Log:
Started generic cloning based on GC support.  This should provide
exactly what is needed by the simple thread cloning approach
discussed on pypy-dev.  Doing it at the GC level also looks like
a good plan.

+Introduction
+============
+
+High-level architecture, VM portability+flexibility goals with comparisons
+
+System programming with Python
+==============================
+
+* PyPy in RPython
+* RTyper helpers (ll, oo type systems)
+* GC
+
+Manipulatable, e.g. as in Stackless Transform
+
+Type inference details
+======================
+
+Flow space, annotator overviews
+
+Not very precise, no automatic polymorphism, but easy to control, fast, easy
+and to reuse with different type systems: RPython, ll, oo, rctypes,
+BTA (binding-time analysis for the JIT)...  easy custom specializations

+we had a bit of a chat in the pypy-sync meeting on 2006-05-18 about the talks
+we want to give at europython this year.  we decided that we might give up to 4
+talks:
+
+    1. an introductory talk, probably based on michael's talk from the accu
+       conference (but likely a bit shorter)
+
+    2. a "what pypy can do for you" talk, covering the ext-compiler, stackless,
+       etc.
+
+    3. an architecture session, similar to that held at pycon this year.
+
+    4. a talk on the methodology side of the project.
+
+In addition Eric will probably give a lightning talk about the JS backend.

+  We talked about the requirements for a paper at the Dynamic Language

+  (probably) or should (probably not) reuse material from our WP05 reports.
+  It was agreed that Samuele and Armin would spend a little time working on
+  an outline before Samuele goes on holiday on Monday.  This is in
+   so far.
+
+  The deadline is June 1.
+
+  We also talked about how many talks we should submit to EuroPython

+
+  We didn't really get to this in any meaningful way.  Try again next week?
+
+* any other business?
+
+  Samuele noted that translation with --new-stackless is very, very slow.
+  Michael responded that he was running a version with profiling using
+  lsprof to see if he could find any obvious stupidities.  This translation
+  has still not finished, nearly 24 hours later, so it must be breaking all
+  known records for longest translation...

+    [16:38]  i am curious if you considered a research or an experience paper
+    [16:38]  or both :)
+    [16:39]  well, I think the idea is to write an overview paper, describing how basic techniques: type inference/ abstract interpreation
+    [16:39]  based on the d05 papers?
+    [16:40]  i mean the work package 5 papers
+    [16:40]  shortly and then seeing how this are repeatedly used through the tool chain and to impose types on our singled langague
+    [16:40]  and what can we achieve with this
+    [16:40]  hpk: much more overviewish, I think
+    [16:41]  s/singled .../single not statically typed language
+    [16:41]  do we know e.g. how long papers are expected to be?
+    [16:41]  mwh: max 12 pages in PDF
+    [16:41]  and they require the "ACM format"
+    [16:42]  right
+    [16:42]  that's just a style file with the latex, i don't think that's too big a deal
+    [16:42]  ... cfbolz ? :)
+    [16:42]  :-)
+    [16:42]  we will see :-)
+    [16:43]  well, with 12 pages, is hard not to be overviewish
+    [16:43]  right
+    [16:43]  and unless we focused on a single thing
+    [16:43]  and even then
+    [16:43]  we do not have the problem that we couldn't reuse stuff from existing reports though
+    [16:43]  because none of them was published in their sense, or is that not correct?
+    [16:43]  I think it will read differently
+    [16:44]  but yes copying long chunks is not a good idea
+    [16:44]  yip
+    [16:44]  i think that's correct, but possibly not that relevant
+    [16:44]  also I'm not sure we can
+    [16:44]  under the 12 pages constraint
+    [16:44]  we really need to write a fresh text
+    [16:45]  we cannot cram the wp05 report in it
+    [16:45]  which is more than 20 pages
+    [16:45]  so, next question: who writes it
+    [16:45]  pedronis is on holiday next week
+    [16:46]  so arigo and ... ?
+    [16:46]  pedronis: sure, i understood that point (although i am not as sure as you that we cannot use anything of what we already have, including graphics etc.)
+    [16:46]  I can possibly help a bit after next thursday
+    [16:46]  ok
+    [16:46]  or before monday
+    [16:46]  would be nice to have the bones of a report before then
+    [16:46]  oh
+    [16:47]  maybe you and arigo could come up with an outline soon-ish?
+    [16:47]  arigo: we may try to write an outline tomorrow
+    [16:47] Action: hpk thinks he can proof-read and possibly help end next week/early the following
+    [16:48]  ok for me
+    [16:48]  but again, research or experience paper?
+    [16:48]  they seem to make this distinction
+    [16:48]  sounds more like research to me
+    [16:48]  I think experience papers are more about using a language or some features
+    [16:49]  yes research i think
+    [16:49]  ok
+    [16:49]  if we can hurry on
+    [16:49]  how many talks do we want to submit to europython?
+    [16:50]  hpk: is bea going to do a talk in the agility track?
+    [16:50]  mwh: quite likely, yes, i meet her in 10 minutes
+    [16:50]  hpk: coool
+    [16:50]  do we think there's still a market for an introductory talk?
+    [16:50]  i think there probably is
+    [16:51]  mwh: your accu talk is a 80% base talk for that, i'd think
+    [16:51]  it's fairly long though
+    [16:51]  but i guess, do we want to do something else as well?
+    [16:52]  one on the ext-compiler?
+    [16:52]  now comes the potentially interesting talk :-)
+    [16:52]  hpk: that might be good, yes
+    [16:53]  what about the pypy archsession from Pycon?
+    [16:53]  we should have something for the language track
+    [16:54]  the intersection between pycon and EP is not that large, so doing the arch-session + introductory talk (+ maybe ext-compiler) would make sense IMO, but what do you all think?
+    [16:54]  hpk: maybe i'm getting skeptical about the usefulness of that talk
+    [16:54]  I was thinking of giving a pypy-js/genjs talk but there has been to little progress/things to show to make it worth while
+    [16:54]  arigo: it did receive quite positive feedback as far as i heard it, do you know/feel differently?
+    [16:55]  hpk: no, good then
+    [16:55]  I was thinking that it should soon be time to present a language talk
+    [16:55]  about the new language-visible features we can have in PyPy
+    [16:56]  right
+    [16:56]  a "pypy features" talk would be well received, i'd guess
+    [16:56]  and maybe get people away from the speed thing
+    [16:56]  yes, i think so too
+    [16:57]  four pypy related talks might be a bit much though :)
+    [16:57]  yes, I'm worrying a bit that pypy is seen mostly as a large complicated architecture
+    [16:57]  ah ah. people will never get away from the speed thing
+    [16:57]  arigo: you don't worry that it actually _is_ a complicated arch, right? :)
+    [16:57]  never :-)
+    [16:57]  is quite simple in some sense
+    [16:58]  some swiss sense
+    [16:58]  :-)
+    [16:58]  anyway, so let's agree on how to proceed there maybe next week?
+    [16:58]  so, um, we're running out of time
+    [16:58]  well, maybe this could go together with the ext-compiler
+    [16:59]  arigo: yes, pypy features should have 10 minutes about the ext-compiler because that's probably the most real thing
+    [16:59]  pypy agility + pypy intro + pypy features
+    [16:59]  sounds like a plan for now
+    [16:59]  "agility" or "architecture" ?
+    [16:59]  + maybe pypy arch
+    [16:59]  pypy bea/agility
+    [16:59]  is what mwh meant
+    [16:59]  ok
+    [16:59]  pypy bea then :)
+    [16:59]  :-)
+    [17:00]  i think doing the state of the pypy universe in 1 minute is a bit of a stretch
+    [17:00]  "confusing"
+    [17:00]  any other business?
+    [17:00]  ericvrp: but i think a pypy/js focused talk would also make some sense - in the web track :)
+    [17:00]  new-stackless translation is veeeeeery slow
+    [17:00]  i'm profiling now
+    [17:01]  ericvrp: indeed, maybe with fijal even?
+    [17:01]  hpk, the problem is I can not point people to some concrete examples, so it's a bit vague IMO
+    [17:01]  we need to kill the defaults assumption in lltype, we may gain some speed in the gcs
+    [17:01]  ericvrp: maybe, but you do have code that runs in a browser
+    [17:02]  well yes, how many minutes should such a talk be ?
+    [17:02]  well, 30 minutes is the shortest you can do :)
+    [17:03]  there are always lightning talks if you don't want to commit to any results :)
+    [17:03]  I have the feeling that would be better. Real work on genjs will start after europython
+    [17:04]  ok
+    [17:04]  so unless there's anything else, i'd like to close the meeting

Log:
Renamed 'malloced_lists' to 'pools'.  These pools are now GcOpaque
objects themselves, so that they are collectable.  Work in progress.
(Collecting a pool only means collecting the small overhead data, not
all the objects inside the pool, which stay alive as usual as long as
they are referenced.)

New Revision: 27495

Modified:
   pypy/dist/pypy/translator/microbench/pybench/pybench.py
Log:
A little toy for making Html reports of pybench benchmarks. There are some problems though. The benchmark results cant be pickled (because of pickling of sys.modules?), when using pypy-c. The sortable tables relies on Mochikit, which maybe should not be part of PyPy?

Log:
a rather cheating implementation of x_become, basically copying collect() and
adding a couple of choice lines.

however it fails, in a way that doesn't seem to make much sense, even if you
make the body of x_become() exactly like that of collect() -- it seems the
frame chains get corrupted or something :(

A pygame viewer for lltype data structures.  There is an lloperation
that will display one or several pointers or addresses, and you
click your way along further pointers.  Used from llhelpers as:

Added a 'debug_print' low-level operation.  Saner than using os.write()
for debugging the gc, because os.write() requires allocating strings for
the formatting...  This operation also produces reasonable-looking C
code.

Log:
(pedronis, arigo)

Yikes!  The problem was about the stackless transform.  It contained a hard-coded
list of operations that can possibly unwind the stack.  Moreover, even if it knew
about the new gc_x_*() operations, the exception transform would kill the
UnwindException branch without a canraise=... in LLOp().  So we added a flag
'canraisegc=True' that prevents both things from going wrong.

test_tree_cloning passes now!  Cloning seems to be working well enough that we
can try to expose it to RPython and see.

Log:
making a branch to checkin my rough experiments with explicit resume points

too unfinished to check it on the trunk, OTOH the first test passes on the llinterp.

Log:
rough experiment on  explicit resume points with stackless transformed code:
primitives:

resume_point(LABEL, values to restore vars, [returs=var])
resume_after(TYP, LABEL, values for var to restore [returns=value for return])

the first test in test_resume_point works on the llinterp.

too unpolished/incomplete for the trunk tough. there are also some open issues. There may be oversights
and some things are quite hackish: I wanted to quickly explore how hard this would be.

* added pypy.rpython.rgc with an RPython interface to the gc_x_swap_pool
  and gc_x_clone operations.

* made SomeExternalObject use the extregistry too.

* bug fixes; extended cast_opaque_ptr to also do a cast_pointer for
  you.

+
Security ideas

+
These are some notes I (Armin) took after a talk at Chalmers by Steve
+Zdancewic: "Encoding Information Flow in Haskell".  That talk was
+presenting a pure Haskell approach with monad-like constructions; I
+think that the approach translates well to PyPy at the level of RPython.

+

+
The problem

+
The problem that we try to solve here is: how to give the programmer a
+way to write programs that are easily checked to be "secure", in the
+sense that bugs shouldn't allow confidential information to be
+unexpectedly leaked.  This is not security as in defeating actively
+malicious attackers.

+

+

+
Example

+
Let's suppose that we want to write a telnet-based application for a
+bidding system.  We want normal users to be able to log in with their
+username and password, and place bids (i.e. type in an amount of money).
+The server should record the highest bid so far but not allow users to
+see that number.  Additionally, the administrator should be able to log
+in with his own password and see the highest bid.  The basic program:

+
+def mainloop():
+    while True:
+        username = raw_input()
+        password = raw_input()
+        user = authenticate(username, password)
+        if user == 'guest':
+            serve_guest()
+        elif user == 'admin':
+            serve_admin()
+
+def serve_guest():
+    global highest_bid
+    print "Enter your bid:"
+    n = int(raw_input())
+    if n > highest_bid:     #
+        highest_bid = n     #
+    print "Thank you"
+
+def serve_admin():
+    print "Highest big is:", highest_bid
+

+
The goal is to make this program more secure by declaring and enforcing
+the following properties: first, the guest code is allowed to manipulate
+the highest_bid, as in the lines marked with #, but these lines must
+not leak back the highest_bid in a form visible to the guest user;
+second, the printing in serve_admin() must only be allowed if the user
+that logged in is really the administrator (e.g. catch bugs like
+accidentally swapping the serve_guest() and serve_admin() calls in
+mainloop()).

+

+

+
Preventing leak of information in guest code: 1st try

+
The basic technique to prevent leaks is to attach "confidentiality
+level" tags to objects.  In this example, the highest_bid int object
+would be tagged with label="secret", e.g. by being initialized as:

+
+highest_bid = tag(0, label="secret")
+

+
At first, we can think about an object space where all objects have such
+a label, and the label propagates to operations between objects: for
+example, code like highest_bid += 1 would produce a new int object
+with again label="secret".

+
Where this approach doesn't work is with if/else or loops.  In the above
+example, we do:

+
+if n > highest_bid:
+    ...
+

+
However, by the object space rules introduced above, the result of the
+comparison is a "secret" bool objects.  This means that the guest code
+cannot know if it is True or False, and so the PyPy interpreter has no
+clue if it must following the then or else branch of the if.
+So the guest code could do highest_bid += 1 and probably even
+highest_bid = max(highest_bid, n) if max() is a clever enough
+built-in function, but clearly this approach doesn't work well for more
+complicated computations that we would like to perform at this point.

+
There might be very cool possible ideas to solve this with doing some
+kind of just-in-time flow object space analysis.  However, here is a
+possibly more practical approach.  Let's forget about the object space
+tricks and start again.  (See Related work for why the object space
+approach doesn't work too well.)

+

+

+
Preventing leak of information in guest code with the annotator instead

+
Suppose that the program runs on top of CPython and not necessarily
+PyPy.  We will only need PyPy's annotator.  The idea is to mark the code
+that manipulates highest_bid explicitly, and make it RPython in the
+sense that we can take its flow space and follow the calls (we don't
+care about the precise types here -- we will use different annotations).
+Note that only the bits that manipulates the secret values needs to be
+RPython.  Example:

+
+# on top of CPython, 'hidden' is a type that hides a value without
+# giving any way to normal programs to access it, so the program
+# cannot do anything with 'highest_bid'
+
+highest_bid = hidden(0, label="secure")
+
+def enter_bid(n):
+    if n > highest_bid.value:
+        highest_bid.value = n
+
+enter_bid = secure(enter_bid)
+
+def serve_guest():
+    print "Enter your bid:"
+    n = int(raw_input())
+    enter_bid(n)
+    print "Thank you"
+

+
The point is that the expression highest_bid.value raises a
+SecurityException when run normally: it is not allowed to read this
+value.  The secure() decorator uses the annotator on the enter_bid()
+function, with special annotations that I will describe shortly.  Then
+secure() returns a "compiled" version of enter_bid.  The compiled
+version is checked to satisfy the security constrains, and it contains
+special code that then enables the highest_bid.value to work.

+
The annotations propagated by secure() are SomeSecurityLevel
+annotations.  Normal constants are propagated as
+SomeSecurityLevel("public").  The highest_bid.value returns the
+annotation SomeSecurityLevel("secret"), which is the label of the
+constant highest_bid hidden object.  We define operations between
+two SomeSecurityLevels to return a SomeSecurityLevel which is the max of
+the secret levels of the operands.

+
The key point is that secure() checks that the return value is
+SomeSecurityLevel("public").  It also checks that only
+SomeSecurityLevel("public") values are stored e.g. in global data
+structures.

+
In this way, any CPython code like serve_guest() can safely call
+enter_bid(n).  There is no way to leak information about the current
+highest bid back out of the compiled enter_bid().

+

+

+
Declassification

+
Now there must be a controlled way to leak the highest_bid value,
+otherwise it is impossible even for the admin to read it.  Note that
+serve_admin(), which prints highest_bid, is considered to "leak" this
+value because it is an input-output, i.e. it escapes the program.  This
+is a leak that we actually want -- the terminology is that serve_admin()
+must "declassify" the value.

+
To do this, there is a capability-like model that is easy to implement
+for us.  Let us modify the main loop as follows:

+
+def mainloop():
+    while True:
+        username = raw_input()
+        password = raw_input()
+        user, priviledge_token = authenticate(username, password)
+        if user == 'guest':
+            serve_guest()
+        elif user == 'admin':
+            serve_admin(priviledge_token)
+        del priviledge_token   # make sure nobody else uses it
+

+
The idea is that the authenticate() function (shown later) also returns
+a "token" object.  This is a normal Python object, but it should not be
+possible for normal Python code to instantiate such an object manually.
+In this example, authenticate() returns a priviledge("public") for
+guests, and a priviledge("secret") for admins.  Now -- and this is
+the insecure part of this scheme, but it is relatively easy to control
+-- the programmer must make sure that these priviledge_token objects
+don't go to unexpected places, particularly the "secret" one.  They work
+like capabilities: having a reference to them allows parts of the
+program to see secret information, of a confidentiality level up to the
+one corresponding to the token.

+
Now we modify serve_admin() as follows:

+

+

+
def serve_admin(token):

+
print "Highest big is:", declassify(highest_bid, token=token)

+

+

+
The declassify() function reads the value if the "token" is priviledged
+enough, and raises an exception otherwise.

+
What are we protecting here?  The fact that we need the administrator
+token in order to see the highest bid.  If by mistake we swap the
+serve_guest() and serve_admin() lines in mainloop(), then what occurs is
+that serve_admin() would be called with the guest token.  Then
+declassify() would fail.  If we assume that authenticate() is not buggy,
+then the rest of the program is safe from leak bugs.

+
There are another variants of declassify() that are convenient.  For
+example, in the RPython parts of the code, declassify() can be used to
+control more precisely at which confidentiality levels we want which
+values, if there are more than just two such levels.  The "token"
+argument could also be implicit in RPython parts, meaning "use the
+current level"; normal non-RPython code always runs at "public" level,
+but RPython functions could run with higher current levels, e.g. if they
+are called with a "token=..." argument.

+
(Do not confuse this with what enter_bid() does: enter_bid() runs at the
+public level all along.  It is ok for it to compute with, and even
+modify, the highest_bid.value.  The point of enter_bid() was that by
+being an RPython function the annotator can make sure that the value, or
+even anything that gives a hint about the value, cannot possibly escape
+from the function.)

+
It is also useful to have "globally trusted" administrator-level RPython
+functions that always run at a higher level than the caller, a bit like
+Unix programs with the "suid" bit.  If we set aside the consideration
+that it should not be possible to make new "suid" functions too easily,
+then we could define the authenticate() function of our server example
+as follows:

+
+def authenticate(username, password):
+    database = {('guest', 'abc'): priviledge("public"),
+                ('admin', '123'): priviledge("secret")}
+    token_obj = database[username, password]
+    return username, declassify(token_obj, target_level="public")
+
+authenticate = secure(authenticate, suid="secret")
+

+
The "suid" argument makes the compiled function run on level "secret"
+even if the caller is "public" or plain CPython code.  The declassify()
+in the function is allowed because of the current level of "secret".
+Note that the function returns a "public" tuple -- the username is
+public, and the token_obj is declassified to public.  This is the
+property that allows CPython code to call it.

+
Of course, like a Unix suid program the authenticate() function could be
+buggy and leak information, but like suid programs it is small enough
+for us to feel that it is secure just by staring at the code.

+
An alternative to the suid approach is to play with closures, e.g.:

+
+def setup():
+    #initialize new levels -- this cannot be used to access existing levels
+    public_level = create_new_priviledge("public")
+    secret_level = create_new_priviledge("secret")
+
+    database = {('guest', 'abc'): public_level,
+                ('admin', '123'): secret_level}
+
+    def authenticate(username, password):
+        token_obj = database[username, password]
+        return username, declassify(token_obj, target_level="public",
+                                               token=secret_level)
+
+    return secure(authenticate)
+
+authenticate = setup()
+

+
In this approach, declassify() works because it has access to the
+secret_level token.  We still need to make authenticate() a secure()
+compiled function to hide the database and the secret_level more
+carefully; otherwise, code could accidentally find them by inspecting
+the traceback of the KeyError exception if the username or password is
+invalid.  Also, secure() will check for us that authenticate() indeed
+returns a "public" tuple.

+
This basic model is easy to extend in various directions.  For example
+secure() RPython functions should be allowed to return non-public
+results -- but then they have to be called either with an appropriate
+"token=..."  keyword, or else they return hidden objects again.  They
+could also be used directly from other RPython functions, in which the
+level of what they return is propagated.

+

+

+
Related work

+
What I'm describing here is nothing more than an adaptation of existing
+techniques to RPython.

+
It is noteworthy to mention at this point why the object space approach
+doesn't work as well as we could first expect.  The distinction between
+static checking and dynamic checking (with labels only attached to
+values) seems to be well known; also, it seems to be well known that the
+latter is too coarse in practice.  The problem is about branching and
+looping.  From the object space' point of view it is quite hard to know
+what a newly computed value really depends on.  Basically, it is
+difficult to do better than: after is_true() has been called on a secret
+object, then we must assume that all objects created are also secret
+because they could depend in some way on the truth-value of the previous
+secret object.

+
The idea to dynamically use static analysis is the key new idea
+presented by Steve Zdancewic in his talk.  You can have small controlled
+RPython parts of the program that must pass through a static analysis,
+and we only need to check dynamically that some input conditions are
+satisfied when other parts of the program call the RPython parts.
+Previous research was mostly about designing languages that are
+completely statically checked at compile-time.  The delicate part is to
+get the static/dynamic mixture right so that even indirect leaks are not
+possible -- e.g. leaks that would occur from calling functions with
+strange arguments to provoke exceptions, and where the presence of the
+exception or not would be information in itself.  This approach seems to
+do that reliably.  (Of course, at the talk many people including the
+speaker were wondering about ways to move more of the checking at
+compile-time, but Python people won't have such worries :-)

+            if user == 'guest':

+tricks and start again.  (See `Related work`_ for why the object space
+approach doesn't work too well.)
+
+
+Preventing leak of information in guest code with the annotator instead
+-----------------------------------------------------------------------
+
+Suppose that the program runs on top of CPython and not necessarily
+PyPy.  We will only need PyPy's annotator.  The idea is to mark the code
+that manipulates highest_bid explicitly, and make it RPython in the
+sense that we can take its flow space and follow the calls (we don't
+care about the precise types here -- we will use different annotations).
+Note that only the bits that manipulates the secret values needs to be
+RPython.  Example::
+
+    # on top of CPython, 'hidden' is a type that hides a value without
+    # giving any way to normal programs to access it, so the program
+    # cannot do anything with 'highest_bid'
+
+    highest_bid = hidden(0, label="secure")
+
+    def enter_bid(n):
+        if n > highest_bid.value:
+            highest_bid.value = n
+
+    enter_bid = secure(enter_bid)
+
+    def serve_guest():
+        print "Enter your bid:"
+        n = int(raw_input())
+        enter_bid(n)
+        print "Thank you"
+
+The point is that the expression ``highest_bid.value`` raises a
+SecurityException when run normally: it is not allowed to read this
+value.  The secure() decorator uses the annotator on the enter_bid()
+function, with special annotations that I will describe shortly.  Then
+secure() returns a "compiled" version of enter_bid.  The compiled
+version is checked to satisfy the security constrains, and it contains
+special code that then enables the ``highest_bid.value`` to work.
+
+The annotations propagated by secure() are ``SomeSecurityLevel``
+annotations.  Normal constants are propagated as
+SomeSecurityLevel("public").  The ``highest_bid.value`` returns the
+annotation SomeSecurityLevel("secret"), which is the label of the
+constant ``highest_bid`` hidden object.  We define operations between
+two SomeSecurityLevels to return a SomeSecurityLevel which is the max of
+the secret levels of the operands.
+
+The key point is that secure() checks that the return value is
+SomeSecurityLevel("public").  It also checks that only
+SomeSecurityLevel("public") values are stored e.g. in global data
+structures.
+
+In this way, any CPython code like serve_guest() can safely call
+``enter_bid(n)``.  There is no way to leak information about the current
+highest bid back out of the compiled enter_bid().
+
+
+Declassification
+----------------
+
+Now there must be a controlled way to leak the highest_bid value,
+otherwise it is impossible even for the admin to read it.  Note that
+serve_admin(), which prints highest_bid, is considered to "leak" this
+value because it is an input-output, i.e. it escapes the program.  This
+is a leak that we actually want -- the terminology is that serve_admin()
+must "declassify" the value.
+
+To do this, there is a capability-like model that is easy to implement
+for us.  Let us modify the main loop as follows::
+
+    def mainloop():
+        while True:
+            username = raw_input()
+            password = raw_input()
+            user, priviledge_token = authenticate(username, password)
+            if user == 'guest':
+                serve_guest()
+            elif user == 'admin':
+                serve_admin(priviledge_token)
+            del priviledge_token   # make sure nobody else uses it
+
+The idea is that the authenticate() function (shown later) also returns
+a "token" object.  This is a normal Python object, but it should not be
+possible for normal Python code to instantiate such an object manually.
+In this example, authenticate() returns a ``priviledge("public")`` for
+guests, and a ``priviledge("secret")`` for admins.  Now -- and this is
+the insecure part of this scheme, but it is relatively easy to control
+-- the programmer must make sure that these priviledge_token objects
+don't go to unexpected places, particularly the "secret" one.  They work
+like capabilities: having a reference to them allows parts of the
+program to see secret information, of a confidentiality level up to the
+one corresponding to the token.
+
+Now we modify serve_admin() as follows:
+
+    def serve_admin(token):
+        print "Highest big is:", declassify(highest_bid, token=token)
+
+The declassify() function reads the value if the "token" is priviledged
+enough, and raises an exception otherwise.
+
+What are we protecting here?  The fact that we need the administrator
+token in order to see the highest bid.  If by mistake we swap the
+serve_guest() and serve_admin() lines in mainloop(), then what occurs is
+that serve_admin() would be called with the guest token.  Then
+declassify() would fail.  If we assume that authenticate() is not buggy,
+then the rest of the program is safe from leak bugs.
+
+There are another variants of declassify() that are convenient.  For
+example, in the RPython parts of the code, declassify() can be used to
+control more precisely at which confidentiality levels we want which
+values, if there are more than just two such levels.  The "token"
+argument could also be implicit in RPython parts, meaning "use the
+current level"; normal non-RPython code always runs at "public" level,
+but RPython functions could run with higher current levels, e.g. if they
+are called with a "token=..." argument.
+
+(Do not confuse this with what enter_bid() does: enter_bid() runs at the
+public level all along.  It is ok for it to compute with, and even
+modify, the highest_bid.value.  The point of enter_bid() was that by
+being an RPython function the annotator can make sure that the value, or
+even anything that gives a hint about the value, cannot possibly escape
+from the function.)
+
+It is also useful to have "globally trusted" administrator-level RPython
+functions that always run at a higher level than the caller, a bit like
+Unix programs with the "suid" bit.  If we set aside the consideration
+that it should not be possible to make new "suid" functions too easily,
+then we could define the authenticate() function of our server example
+as follows::
+
+    def authenticate(username, password):
+        database = {('guest', 'abc'): priviledge("public"),
+                    ('admin', '123'): priviledge("secret")}
+        token_obj = database[username, password]
+        return username, declassify(token_obj, target_level="public")
+
+    authenticate = secure(authenticate, suid="secret")
+
+The "suid" argument makes the compiled function run on level "secret"
+even if the caller is "public" or plain CPython code.  The declassify()
+in the function is allowed because of the current level of "secret".
+Note that the function returns a "public" tuple -- the username is
+public, and the token_obj is declassified to public.  This is the
+property that allows CPython code to call it.
+
+Of course, like a Unix suid program the authenticate() function could be
+buggy and leak information, but like suid programs it is small enough
+for us to feel that it is secure just by staring at the code.
+
+An alternative to the suid approach is to play with closures, e.g.::
+
+    def setup():
+        #initialize new levels -- this cannot be used to access existing levels
+        public_level = create_new_priviledge("public")
+        secret_level = create_new_priviledge("secret")
+
+        database = {('guest', 'abc'): public_level,
+                    ('admin', '123'): secret_level}
+
+        def authenticate(username, password):
+            token_obj = database[username, password]
+            return username, declassify(token_obj, target_level="public",
+                                                   token=secret_level)
+
+        return secure(authenticate)
+
+    authenticate = setup()
+
+In this approach, declassify() works because it has access to the
+secret_level token.  We still need to make authenticate() a secure()
+compiled function to hide the database and the secret_level more
+carefully; otherwise, code could accidentally find them by inspecting
+the traceback of the KeyError exception if the username or password is
+invalid.  Also, secure() will check for us that authenticate() indeed
+returns a "public" tuple.
+
+This basic model is easy to extend in various directions.  For example
+secure() RPython functions should be allowed to return non-public
+results -- but then they have to be called either with an appropriate
+"token=..."  keyword, or else they return hidden objects again.  They
+could also be used directly from other RPython functions, in which the
+level of what they return is propagated.
+
+
+Related work
+------------
+
+What I'm describing here is nothing more than an adaptation of existing
+techniques to RPython.
+
+It is noteworthy to mention at this point why the object space approach
+doesn't work as well as we could first expect.  The distinction between
+static checking and dynamic checking (with labels only attached to
+values) seems to be well known; also, it seems to be well known that the
+latter is too coarse in practice.  The problem is about branching and
+looping.  From the object space' point of view it is quite hard to know
+what a newly computed value really depends on.  Basically, it is
+difficult to do better than: after is_true() has been called on a secret
+object, then we must assume that all objects created are also secret
+because they could depend in some way on the truth-value of the previous
+secret object.
+
+The idea to dynamically use static analysis is the key new idea
+presented by Steve Zdancewic in his talk.  You can have small controlled
+RPython parts of the program that must pass through a static analysis,
+and we only need to check dynamically that some input conditions are
+satisfied when other parts of the program call the RPython parts.
+Previous research was mostly about designing languages that are
+completely statically checked at compile-time.  The delicate part is to
+get the static/dynamic mixture right so that even indirect leaks are not
+possible -- e.g. leaks that would occur from calling functions with
+strange arguments to provoke exceptions, and where the presence of the
+exception or not would be information in itself.  This approach seems to
+do that reliably.  (Of course, at the talk many people including the
+speaker were wondering about ways to move more of the checking at
+compile-time, but Python people won't have such worries :-)

Log:
Create a profile based optimized executable from the llvm c backend generated file.
The exe this produces is twice as fast as the one generated with the llvm x86 backend.
This version uses genc's exception transformer + the raisingop2direct_call transformer +
some hackish code that uses a ringbuffer instead of garbage collected malloced data for
short lived exception.
It produces the fastest pypy so far (some 3.3x slower that CPython).

Log:
- Added support for float to string conversion to ootypesystem. 

- Removed the temporary oostring2 which was used for playing with
ooregistry.

- Moved oostring and ooparse_int implementatio to ooregistry.py.

Due to the use of extregistry now tests should import
ootypesystem.ooregistry so that entries are registered.

Log:
Trying to sort out the dependencies in order between the stackless and
the gc transforms.  The isgchelper flag was getting in the way because
gc helpers must almost all be stackless transformed too (e.g. to allow
UnwindException to pass through a call to a destructor).

Some obscure hacks now allow cooperation between the mixlevelannotator
and the genc database about delayed functions.  It is now ok to get()
delayed function pointers.  It forces the unique pypy_g_* name of the
function to be computed, but the FuncNode is not built.  Instead, the
complete() method periodically checks if these delayed pointers have
been resolved (e.g. by a finish()).

The finish() of the gc transformer is now in two parts: finish_helpers()
finishes the mixlevelannotator; then finish_tables() computes the
final GC tables.

Documented in complete() the precise order in which these finish() are
called and why.

+        #    not followed at this point.  User finalizers (__del__) on the
+        #    other hand are followed during this step too.
+        #
+        # 2. gctransformer.finish_helpers() - after this, all functions in
+        #    the program have been rtyped.
+        #
+        # 3. follow new dependencies.  All previously delayed functions
+        #    should have been resolved by 2 - they are gc helpers, like
+        #    ll_finalize().  New FuncNodes are built for them.  No more

+        #
+        # 5. follow new dependencies (this should be only the new frozen
+        #    table, which contains only numbers and already-seen function
+        #    pointers).

the ambiant stdlib into the _cache!  Crash with 2.5 where its body
changed to accomodate for a change in _codecs that our own
2.4-compatible _codecs does not provide.

+                  Still Missing a Cool Title
+************************************************************
+
+:Abstract:
+
+    The PyPy project seeks to prove both on a research and on a
+    practical level the feasability of writing a virtual machine (VM)
+    for a dynamic language in a dynamic language - in this case, Python.
+    The aim is to translate (i.e. compile) the VM to arbitrary target
+    environments, ranging in level from C/Posix to Smalltalk/Squeak via
+    Java and CLI/.NET, while still being of reasonable efficiency within
+    that environment.
+
+    A key tool to achieve this goal is the systematic reuse of the
+    (unmodified, dynamically typed) Python language as a system
+    programming language at various levels of our architecture and
+    translation process.  For each level, we design a corresponding type
+    system and apply a generic type inference engine - for example, the
+    garbage collector (GC) is written in a style that manipulates
+    simulated pointer and address objects, and when translated to C
+    these operations become C-level pointer and address instructions.

+============================================================
+                         Introduction
+============================================================
+
+
+Despite the constant trend in the programming world towards portability
+and reusability, there are some areas in which it is still notoriously
+difficult to write flexible, portable, and reasonably efficient
+programs.  Virtual machines (VM) is one such area.  Building
+implementations of general programming languages, in particular highly
+dynamic ones, is typically a long-winded effort and produces a result
+that is quite tailored to a specific platform.  For this and other
+reasons, standard platforms emerge; nowadays, a language implementor
+could cover most general platforms in use by writing three versions of
+his VM: for C/Posix, for Java, and for CLI/.NET.  This is, at least, the
+current situation of the Python programming language, where independent
+volunteers developped and are now maintaining Java and .NET versions of
+Python, which follow the evolution of the "official" C version
+(CPython).
+
+However, we believe that platform standardization does not have to be a
+necessary component of this equation.  We are basically using the
+standard "metaprogramming" argument: if one could write the VM in a
+very-high-level language, then the VM itself could be automatically
+*translated* to any lower-level platform.  Moreover by writing the VM in
+such a language we would gain in flexibility and expressivity.
+
+PyPy achieves this goal without giving up on the efficiency of the
+compiled VMs.  The key factors enabling this result are not to be found
+in recent advances in any particular research area - we are not using
+any sophisticated GC, any constraint-based type inference, any advanced
+mega-programming concepts.  Instead, we are following a novel overall
+architecture: it is split in many levels of stepwise translation from
+the high-level source of the VM to the final target platform.  Similar
+platforms can reuse many of these steps, while for very different
+platforms we have the option to perform very different translation
+steps.  Each step reuses a common type inference component, but with a
+different type system.
+
+Experiments also suggest a more mundane reason why such an approach is
+only practical today: a typical translation takes about an hour on a
+modern PC and consumes close to 1GB of RAM.
+
+We shortly describe the architecture of PyPy in `section 2`_.  In
+`section 3`_ we describe our approach of varying the type systems at
+various levels of the translation.  `Section 4`_ gives an overview of
+the type inferencer we developped.  We present experimental results in
+`section 5`_ and future work directions in `section 6`_.  In `section 7`_
+we compare with related work, and finally we conclude in `section 8`_.

+the one hand an implementation of the Python programming language,
+mostly complete and compliant with the current version of the language,

+is a translation toolsuite whose goal is, roughly speaking, to compile
+various subsets of Python to various environment.

Log:
small optimization in stackless: don't safe state for tail calls. need to fix
some tests, because they were tail calls, so the stack-depth was wrong :-).
This makes pypy-c-stackless slightly smaller (125 kb less code).

Modified:

Log:
Modified the debug_view in such a way that we can see the pointers that
we passed in as argument, so e.g. it is clear when we pass it twice the
same pointer (as is the case in my failing test, where the supposely
cloned coroutine is actually the same object as its original).

Subject: [pypy-svn] r27663 - in pypy/dist/pypy/translator/cli: . src test
Message-ID: <20060524212135.7A3441006E@code0.codespeak.net>

Author: antocuni
Date: Wed May 24 23:21:22 2006
New Revision: 27663

Added:
   pypy/dist/pypy/translator/cli/test/test_runtest.py   (contents, props changed)
Modified:
   pypy/dist/pypy/translator/cli/cts.py
   pypy/dist/pypy/translator/cli/src/pypylib.cs
   pypy/dist/pypy/translator/cli/test/runtest.py
Log:
Added the class CliTest: it is intended to be used togheter with
classes in pypy.rpython.test.tool, so that tests written for rpython
can be used for gencli with no effort.

+There are two major components in PyPy:
 
+1. the *Standard Interpreter*: an implementation of the Python programming
+language, mostly complete and compliant with the current version of the
+language, Python 2.4.
+
+2. the *Translation Process*: a translation tool-suite whose goal is to
+compile subsets of Python to various environment.
+
+In particular, we have defined a subset of the Python language called
+"restricted Python" or RPython.  This sublanguage is not restricted
+syntactically, but only in the way it manipulates objects of different
+types.  The restrictions are a compromise between the expressivity and
+the need to statically infer enough types to generate efficient code.
+The foremost purpose of the translation tool-suite is to compile such
+RPython programs to a variety of different platforms.
+
+Our current efforts, and the present paper, focus on this tool-suite.
+We will not talk about the Standard Interpreter component of PyPy in the
+sequel, other than mention that it is written in RPython and can thus be
+translated.  At close to 90'000 lines of code, it is the largest RPython
+program that we have translated so far.  More information can be found
+in `[1]`_.

 PyPy achieves this goal without giving up on the efficiency of the
 compiled VMs.  
 
-The key factors enabling this result are not to be found
-in recent advances in any particular research area - we are not using
-any sophisticated GC, any constraint-based type inference, any advanced
-meta-programmingconcepts.
-[this claim formulated this way is confusing, the GC aspect is marginal
-and we could adopt a sophisticated GC, the constraint based type inference
-is pertinent, but the meta-programming is a bit too vague,
-there's no accepted definition of what should be considered advanced meta-programming, and what we do is meta-programming for some definition,
-I would just cite the constraint type inference as example, and be happy]
-
-Instead, we are following a novel overall architecture: it is split
-into many levels of stepwise translation from the high-level source of

-XXX
+The translation process
+-----------------------
+
+The translation process starts from RPython source code and eventually
+produces low-level code suitable for the target environment.  It can be
+described as performing a series of step-wise transformations.  Each
+step is based on control flow graph transformations and rewriting, and
+on the ability to augment the program with further implementation code
+written in Python and analysed with the suitable type system.
+
+The front-end part of the translation process analyses the input RPython
+program in two phases, as follows [#]_:
+
+.. [#] Note that the two phases are intermingled in time, because type
+       inference proceeds from an entry point function and follows all
+       calls, and thus only gradually discovers (the reachable parts of)
+       the input program.
+
+``[figure: flow graph and annotator, e.g. part of doc/image/translation.*]``
+
+1. We take as input RPython functions, and convert them to control flow
+   graphs -- a structure amenable to analysis.  These flow graphs contain
+   polymorphic operations only: in Python, almost all operations are
+   dynamically overloaded by type, whereas the absence of macros means
+   that the control flow is static.
+
+2. We perform type inference on the control flow graphs.  At this stage,
+   types inferred are part of the type system which is the very definition
+   of the RPython sub-language: they are roughly a subset of Python's
+   built-in types, with some more precision to describe e.g. the
+   items stored in container types.  Occasionally, a single input function
+   can produce several specialized versions, i.e. several similar but
+   differently typed graphs.  This type inference process is described in
+   more details in `section 4`_.
+
+At the end of the front-end analysis, the input RPython program is
+represented as a forest of flow graphs with typed variables.  Following
+this analysis are a number of transformation steps.  Each transformation
+step modifies the graphs in-place, by altering their structure and/or
+the operations they contain.  Each step inputs graphs typed in one type
+system and leaves them typed in a possibly different type system, as we
+will describe in the sequel.  Finally, a back-end turns the resulting
+graphs into code suitable for the target environment, e.g. C source code
+ready to be compiled.
+
+
+Transformations
+---------------
+
+When the translation target is C or C-like environments, the first of
+the transformation steps takes the RPython-typed flow graphs, still
+containing polymorphic operations only, and produces flow graphs with
+monomorphic C-like operations and C-like types.  In the simplest case,
+this is the only transformation step: these graphs are directly fed to
+the C back-end, which turns them into ANSI C source code.
+
+But RPython comes with automatic memory management, and this first
+transformation step produces flow graphs that also assume automatic
+memory management.  Generating C code directly from there produces a
+fully leaking program, unless we link it with an external garbage
+collector (GC) like the Boehm conservative GC [Boehm], which is a viable
+option.
+
+We have two alternatives, each implemented as a transformation step.
+The first one inserts naive reference counting throughout the whole
+program's graphs, which without further optimizations gives exceedingly
+bad performance (it should be noted that the CPython interpreter is also
+based on reference counting, and experience suggests that it was not a
+bad choice in this particular case; more in `section 5`_).
+
+The other, and better, alternative is an exact GC, coupled with a
+transformation, the *GC transformer*.  It inputs C-level-typed graphs
+and replaces all ``malloc`` operations with calls to a garbage
+collector's innards.  It can inspect all the graphs to discover the
+``struct`` types in use by the program, and assign a unique type id to
+each of them.  These type ids are collected in internal tables that
+describe the layout of the structures, e.g. their sizes and the location
+of the pointer fields.
+
+We have implemented other transformations as well, e.g. performing
+various optimizations, or turning the whole code into a
+continuation-passing style (CPS) that allows us to use coroutines
+without giving up the ability to generate fully ANSI C code.  (This will
+be the subject of another paper.)
+
+Finally, currently under development is a variant of the very first
+transformation step, for use when targetting higher-level,
+object-oriented (OO) environments.  It is currently being designed
+together with back-ends for Smalltalk/Squeak [#]_ and CLI/.NET.  This
+first transformation step, for C-like environments, is called the
+*LLTyper*: it produces C-level flow graphs, where the object-oriented
+features of RPython (classes and instances) become manipulations of C
+structs with explicit virtual table pointers.  By contrast, for OO
+environments the transformation step is called the *OOTyper*: it targets
+a simple object-oriented type system, and preserves the classes and
+instances of the original RPython program.  The LLTyper and OOTyper
+still have much code in common, to convert the more Python-specific
+features like its complex calling conventions.
+
+.. [#] Our simple OO type system is designed for *statically-typed* OO
+       environments, including Java; the presence of Smalltalk as a
+       back-end might be misleading in that respect.
+
+More information about these transformations can be found in `[T]`_.
+
+
+System code
+-----------
+
+A common pattern in all the transformation steps is to somehow lower the
+level at which the graphs are currently expressed.  Because of this,
+there are operations that were atomic in the input (higher-level) graphs
+but that need to be decomposed into several operations in the target
+(lower-level) graphs.  In some cases, the equivalent functionality
+requires more than a couple of operations: a single operation must be
+replaced by a call to whole new code -- functions and classes that serve
+as helpers.  An example of this is the ``malloc`` operation for the GC
+transformer.  Another example is the ``list.append()`` method, which is
+atomic for Python or RPython programs, but needs to be replaced in
+C-level code by a helper that possibly reallocates the array of items.
+
+This means that in addition to transforming the existing graphs, each
+transformation step also needs to insert new functions into the forest.
+A key feature of our approach is that we can write such "system-level"
+code -- relevant only to a particular transformation -- in plain Python
+as well:
+
+.. topic:: Figure 1 - a helper to implement ``list.append()``
+
+  ::
+
+    def ll_append(lst, newitem):
+        # Append an item to the end of the vector.
+        index = lst.length         # get the 'length' field
+        ll_resize(lst, index+1)    # call a helper not shown here
+        itemsarray = lst.items     # get the 'items' field
+        itemsarray[index] = item   # this behaves like a C array
+
+The idea is to feed these new Python functions into the front-end, using
+this time the transformation's target (lower-level) type system during
+the type inference.  In other words, we can write plain Python code that
+manipulates objects that conform to the lower-level type system, and
+have these functions automatically transformed into appropriately typed
+graphs.
+
+For example, ``ll_append()`` in figure 1 is a Python function that
+manipulates objects that behave like C structures and arrays.  This
+function is inserted by the LLTyper, as a helper to implement the
+``list.append()`` calls found in its RPython-level input graphs.  By
+going through the front-end reconfigured to use C-level types, the above
+function becomes a graph with such C-level types [#]_, which is then
+indistinguishable from the other graphs of the forest produced by the
+LLTyper.
+
+.. [#] The low-level type system specifies that the function should be
+       specialized by the C-level type of its input arguments, so it
+       actually turns into one graph per list type - list of integers,
+       list of pointers, etc.  This behavior gives the programmer a
+       feeling comparable to C++ templates, without the declarations.
+
+In the example of the ``malloc`` operation, replaced by a call to GC
+code, this GC code can invoke a complete collection of dead objects, and
+can thus be arbitrarily complicated.  Still, our GC code is entierely
+written in plain Python, and it manipulates "objects" that are still at
+a lower level: pointer and address objects.  Even with the restriction
+of having to use pointer-like and address-like objects, Python remains
+more expressive than, say, C to write a GC.  [see also Jikes]
+
+In the sequel, we will call *system code* functions written in Python
+that are meant to be analysed by the front-end.  For the purpose of this
+article we will restrict this definition to helpers introduced by
+transformations, as opposed to the original RPython program, although
+the difference is not fundamental to the translation process (and
+although our input RPython program, as seen in `section 2`_, is often
+itself a Python virtual machine!).
+
+Note that such system code cannot typically be expressed as normal
+RPython functions, because it corresponds to primitive operations at
+that level.  As an aside, let us remark that the number of primitive
+operations at RPython level is, comparatively speaking, quite large: all
+list and dictionary operations, instance and class attribute accesses,
+many string processing methods, a good subset of all Python built-in
+functions...  Compared to other approaches [e.g. Squeak], we do not try
+to minimize the number of primitives -- at least not at the source
+level.  It is fine to have many primitives at any high enough level,
+because they can all be implemented at the next lower level in a way
+that makes sense to that level.  The key reason why this is not
+burdensome is that the lower level implementations are also written in
+Python - with the only difference that they use (and have to be typeable
+in) the lower-level type system. [#]_
+
+.. [#] This is not strictly true: the type systems are even allowed to
+       co-exist in the same function.  The operations involving
+       higher-level type systems are turned into lower-level operations
+       by the previous transformations in the chain, which leave the
+       already-low-level operations untouched.
+
+
+Type systems
+------------
+
+The four levels that we considered so far are summarized in figure 2.
+
+::
+
+    [figure 2:    RPython
+                  /     \
+                 /       \
+       LLTypeSystem     OOTypeSystem
+               /
+              /
+      Raw addresses
+    ]
+
+The RPython level is a subset of Python, so the types mostly follow
+Python types, and the instances of these types are instances in the
+normal Python sense; e.g. whereas Python has only got a single type
+``list``, RPython has a parametric type ``list(T)`` for every RPython
+type ``T``, but instances of ``list(T)`` are just those Python lists
+whose items are all instances of ``T``.
+
+The other type systems, however, do not correspond to built-in Python
+types.  For each of them, we implemented:
+
+1. the types, which we use to tag the variables of the graphs at the
+   given level.  (Types are mostly just annotated formal terms, and
+   would have been implemented simply as such if Python supported
+   them directly.)
+
+2. the Python objects that emulate instances of these types.  (More
+   about them below.)
+
+We have defined well-typed operations between variables of these types,
+plugging on the standard Python operators.  These operations are the
+ones that the emulating instances implement.  As seen above, the types
+can also be used by type inference when analysing system code like the
+helpers of figure 1.
+
+Now, clearly, the purpose of types like a "C-like struct" or a "C-like
+array" is to be translated to a real ``struct`` or array declaration by
+the C back-end.  What, then, is the purpose of emulating such things in
+Python?  The answer is three-fold.  Firstly, if we have objects that
+live within the Python interpreter, but faithfully emulate the behavior
+of their C equivalent while performing additional safety checks, they
+are an invaluable help for testing and debugging.  For example, we can
+check the correctness of our hash table implementation, written in
+Python in term of struct- and array-like objects, just by running it.
+The same holds for the GC.
+
+Secondly, and anecdotically, as the type inference process (`section
+4`_) is based on abstract interpretation, we can use the following
+trick: the resulting type of most low-level operations is deduced simply
+by example.  Sample C-level objects are instantiated, used as arguments
+to a given operation, and produce a sample result, whose C-leve type
+must be the type of the result variable in the graph.
+
+The third reason is fundamental: we use these emulating objects to
+*represent* pre-built objects at that level.  For example, the GC
+transformer instantiates the objects emulating C arrays for the internal
+type id tables, and it fills them with the correct values.  These array
+objects are then either used directly when testing the GC, or translated
+by the C back-end into static pre-initialized arrays.

+
+
+Building control flow graphs
+----------------------------
+
+As described in the overview of `the translation process`_, the
+front-end of the translation tool-chain works in two phases: it first
+builds control flow graphs from Python functions, and then performs
+whole-program type inference on these graphs.
+
+Remember that building the control flow graphs is not done, as one might
+first expect, by following a function at the syntactic level.  Instead,
+the whole program is imported in a normal Python interpreter; the full
+Python language is used at this point as a kind of preprocessor with
+meta-programming capabilities.  Once the program is imported, the object
+data in memory consists of Python function objects in bytecode format,
+and any other kind of objects created at import-time, like class
+objects, prebuilt instances of those, prebuilt tables, and so on.  Note
+that these objects have typically no text representation any more; for
+example, cyclic data structures may have been built at this point.  The
+translation tool-chain first turns these function objects into in-memory
+control flow graphs which contain direct references to the prebuilt data
+objects, and then handles and transforms these graphs.  We found
+in-process debugging sufficient and did not implement dumping of any
+intermediate step to disk.
+
+The actual transformation from function objects - i.e. bytecode - to
+flow graph is performed by the Flow Object Space, a short but generic
+plug-in component for the Python interpreter of PyPy.  The architecture
+of our Python interpreter is shown in figure 3.
+
+.. topic:: Figure 3 - the interpreter and object spaces
+
+    +------------------------------------------------------+
+    |   forest of bytecode objects from the application    |
+    +------------------------------------------------------+
+    |               Python bytecode interpreter            |
+    +--------------------------------+---------------------+
+    |      Standard Object Space     |  Flow Object Space  |
+    +--------------------------------+---------------------+
+
+Note that the left column, i.e. the bytecode interpreter and the
+Standard Object Space, form the full Python interpreter of PyPy.  It is
+an RPython program, and the whole purpose of the translation process is
+to accept this as *input*, and translate it to an efficient form.  Its
+architecture is not relevant to the way it is translated.
+
+However, the bytecode interpreter plays a double role, at two different
+levels.  The so-called Object Spaces are *domains* in the abstract
+interpretation terminology.  By design, we cleanly separated these
+domains from the bytecode interpreter core; the latter is only
+responsible for decoding the bytecodes of an application and emulating
+the corresponding stack machine.  It treats all actual application-level
+objects as black boxes, and dispatches all operations on them to the
+Object Space.  The Standard Object Space is a concrete domain, in which
+objects are the concrete Python objects of the various built-in types:
+lists, dictionaries, and so on.  By opposition, the Flow Object Space is
+really an abstract domain.  It handles objects that are placeholders.
+Its lattice order is shown in figure 4.
+
+::
+
+    [figure 4:                Variable
+
+                         /      |             \           \
+                        /       |              \           \
+                       /        |               \           \
+      Constant(1) ... Constant(n) ... Constant([1,2,3])  ... Constant() ...
+    ]
+
+This order is extremely simple, because most actual analysis is delayed
+to the next phase, the type inference engine.  The objects are either
+*Variables*, which are pure placeholders for entierely unknown values,
+or *Constants* with a concrete Python object as value.  The order places
+Variable as the top, and keeps all *Constants* unordered.  Thus if two
+different constants merge during abstract interpretation, we immediately
+widen them to Variable.
+
+In conjunction with the Flow Object Space, the bytecode interpreter of
+PyPy thus performs abstract interpretation of Python bytecodes from the
+application. [#]_  In this case, the bytecodes in question come from the
+RPython application that we would like to translate.
+
+.. [#] Note that this process uses the *unmodified* bytecode
+       interpreter.  This means that it is independent of most language
+       details.  Changes in syntax or in bytecode format or opcode semantics
+       only need to be implemented once, in the bytecode interpreter.  In
+       effect, the Flow Object Space enables an interpreter for *any* language
+       to work as a front-end for the rest of the tool-chain.
+
+The Flow Object Space records all operations that the bytecode
+interpreter "would like" to do between the placeholder objects.  It
+records them into basic block objects that will eventually be part of
+the control flow graph of the whole function.  The recorded operations
+take Variables and Constants as argument, and produce new Variables as
+results.  The Constants serve two purposes: they are a way to introduce
+constant values into the flow graphs - these values may be arbitrarily
+complex objects, not just primitives - and they allow basic constant
+propagation. [#]_
+
+.. [#] This is useful at this level for some constructs of the bytecode
+       interpreter, which can temporarily wrap internal values and push them
+       onto the regular value stack among the other application-level objects.
+       We need to be able to unwrap them again later.
+
+In the flow graph, branching occurs when the bytecode interpreter tries
+to inspect the truth value of placeholder objects, as it would in
+response to conditional jump opcodes or other more complicated opcodes:
+at this point, the Flow Object Space starts two new basic blocks and -
+with a technique akin to continuations - tricks the interpreter into
+following both branches, one after the other.  Additionally, the
+bytecode interpreter sends simple positional signals that allow the Flow
+Object Space to detect when control paths merge, or when loops close.
+In this way, abstract interpretation quickly terminates and the recorded
+operations form a graph, which is the control flow graph of the original
+bytecode.
+
+While the Flow Object Space is quite a short piece of code - its core
+functionality holds in 300 lines - the detail of the interactions
+sketched above is not entierely straightforward; we refer the reader to
+`[D]`_ for more information.  Figure 5 shows the control flow graph
+obtained for a simple function (this is a screenshot from our graph
+viewer, used for debugging; basic block placement is performed by
+Graphviz_).

 Type inference
 --------------
 
-XXX
+The type inference engine, which we call the *annotator*, is the central
+component of the front-end part of the translation process.  Given a
+program considered as a family of control flow graphs, the annotator
+assigns to each variable of each graph a so-called *annotation*, which
+describes the possible run-time objects that this variable can contain.
+Following usual terminology, we will call such annotations *types* - not
+to be confused with the Python notion of the concrete type of an object.
+An annotation is a set of possible values, and such a set is not always
+the set of all objects of a specific Python type.
+
+Here is a simplified, static model of how the annotator works.  It can
+be considered as taking as input a finite family of functions calling
+each other, and working on the control flow graphs of each of these
+functions as built by the `Flow Object Space`_.  Additionally, for a
+particular "entry point" function, the annotator is provided with
+user-specified types for the function's arguments.
+
+The goal of the annotator is to find the most precise type that can be
+given to each variable of all control flow graphs while respecting the
+constraints imposed by the operations in which these variables are
+involved.
+
+More precisely, it is usually possible to deduce information about the
+result variable of an operation given information about its arguments.
+For example, we can say that the addition of two integers must be an
+integer.  Most programming languages have this property.  However,
+Python -- like many languages not specifically designed with type
+inference in mind -- does not possess a type system that allows much
+useful information to be derived about variables based on how they are
+*used*; only on how they were *produced*.  For example, a number of very
+different built-in types can be involved in an addition; the meaning of
+the addition and the type of the result depends on the type of the input
+arguments.  Merely knowing that a variable will be used in an addition
+does not give much information per se.  For this reason, our annotator
+works by flowing types forward, operation after operation, i.e. by
+performing abstract interpretation of the flow graphs.  In a sense, it
+is a more naive approach than the one taken by type systems specifically
+designed to enable more advanced inference algorithms.  For example,
+`Hindley-Milner`_ type inference works in an inside-out direction, by
+starting from individual operations and propagating type constraints
+outwards.
+
+Naturally, simply propagating types forward requires the use of a fixed
+point algorithm in the presence of loops in the flow graphs or in the
+inter-procedural call graph.  Indeed, we flow types forward from the
+beginning of the entry point function into each basic block, operation
+after operation, and follow all calls recursively.  During this process,
+each variable along the way gets a type.  In various cases, e.g. when we
+close a loop, the previously assigned types can be found to be too
+restrictive.  In this case, we generalise them to allow for a larger set
+of possible run-time values, and schedule the block where they appear
+for reflowing.  The more general type can generalise the types of the
+results of the variables in the block, which in turn can generalise the
+types that flow into the following blocks, and so on.  This process
+continues until a fixed point is reached.
+
+We can consider that all variables are initially assigned the "bottom"
+type corresponding to the empty set of possible run-time values.  Types
+can only ever be generalised, and the model is simple enough to show
+that there is no infinite chain of generalisation, so that this process
+necessarily terminates.
+
+
+RPython types
+-------------
+
+As seen in `section 3`_, we use the annotator with more than one type
+systems.  The more interesting and complex one is the RPython type
+system, which describes how the input RPython program can be annotated.
+The other type systems contain lower-level, C-like types that are mostly
+unordered, thus forming more trivial lattices than the one formed by
+RPython types.
+
+The set *A* of RPython types is defined as the following formal terms:
+
+* Bot, Top -- the minimum and maximum elements (corresponding to
+  "impossible value" and "most general value");
+
+* Int, NonNegInt, Bool -- integers, known-non-negative integers, booleans;
+
+* Str, Char -- strings, characters (which are strings of length 1);
+
+* Inst(*class*) -- instance of *class* or a subclass thereof (there is
+  one such term per *class*);
+
+* List(*v*) -- list; *v* is a variable summarising the items of the list
+  (there is one such term per variable);
+
+* Pbc(*set*) -- where the *set* is a subset of the (finite) set of all
+  prebuilt constant objects.  This set includes all the callables of the
+  input program: functions, classes, and methods.
+
+* None -- stands for the singleton ``None`` object of Python.
+
+* NullableStr, NullableInst(*class*) - a string or ``None``; resp. an
+  instance or ``None``.
+
+Figures 6 and 7 shows how these types are ordered to form a lattice.  We
+mostly use its structure of `join-semilattice`_ only.
+
+.. graphviz:: image/lattice1.dot
+
+:Figure 6: the lattice of annotations.
+
+.. graphviz:: image/lattice2.dot
+
+:Figure 7: The part about instances and nullable instances, assuming a
+           simple class hierarchy with only two direct subclasses of
+           ``object``.
+
+All list terms for all variables are unordered.  The Pbcs form a
+classical finite set-of-subsets lattice.  In addition, we have left out
+a number of other annotations that are irrelevant for the basic
+description of the annotator and straightforward to handle:
+``Dictionary``, ``Tuple``, ``Float``, ``UnicodePoint``, ``Iterator``,
+etc.  The complete list is described in `[T]`_.
+
+The type system moreover comes with a family of rules, which for every
+operation and every sensible combination of input types describes the
+type of its result variable.  Let *V* be the set of Variables that
+appear in the user program's flow graphs.  Let *b* be a map from *V* to
+*A*; it is a "binding" that gives to each variable a type.  The purpose
+of the annotator is to compute such a binding stepwise.
+
+Let *x*, *y* and *z* be Variables.  We introduce the rule::
+
+         z=add(x,y), b(x)=Int, b(y)=Int
+      ------------------------------------------------------
+               b' = b with (z->Int)
+
+which specify that if we see the addition operation applied to Variables
+whose current binding is ``Int``, a new binding *b'* can be produced:
+it is *b* except on *z*, where we have ``b'(z) = Int``.
+
+The type inference engine can be seen as applying this kind of rules
+repeatedly.  It does not apply them in random order, but follows a
+forward-propagation order typical of abstract interpretation.
+
+It is outside the scope of the present paper to describe the type
+inference engine and the rules more formally.  The difficult points
+involve mutable containers - e.g. initially empty list that are filled
+somewhere else - and the discovery of instance attributes - in Python,
+classes do not declare upfront a fixed set of attributes for their
+instances, let alone their types.  Both these examples require
+sophisticated reflowing techniques that invalidate existing types in
+already-annotated basic blocks, to account for the influence of more
+general types coming indirectly from a possibly distant part of the
+program.  The reader is referred to `[D]`_ for more information.
+
+
+Termination and complexity
+--------------------------
+
+The lattice model clearly contains no infinite chain.  Moreover, it is
+designed to convince oneself that the number of reflowings required in
+practice is small.  For example, we are not trying to do range analysis
+beyond detecting non-negatives - the reason is that range analysis is
+not an essential part of writing *reasonably* efficient code.  Consider
+that a translated RPython program runs hundreds of times faster than
+when the same program is executed by the standard Python interpreter: in
+this context, range analysis appears less critical.  It is a possible
+optimization that we can introduce in a later, optional analysis and
+transformation step.
+
+The worst case behaviors that can appear in the model described above
+involve the lattice of Pbcs, involving variables that could contain e.g.
+one function object among many.  An example of such behavior is code
+manipulating a table of function objects: when an item is read out of
+the table, its type is a large Pbc set: ``Pbc({f1, f2, f3, ...})``.  But
+in this example, the whole set is available at once, and not built
+incrementally by successive discoveries.  This seems to be often the
+case in practice: it is not very common for programs to manipulate
+objects that belong to a large but finite family - and when they do, the
+whole family tends to be available early on, requiring few reflowing.
+
+This means that *in practice* the complete process requires a time that
+is far lower than the worst case.  We have experimentally confirmed
+this: annotating the whole PyPy interpreter (90'000 lines) takes on the
+order of 5 to 10 minutes, and basic blocks are typically only reflown a
+handful of times, providing a close-to-linear practical complexity.
+
+We give formal termination and correctness proofs in `[D]`_, as well as
+worst-case bounds and some experimental evidence of their practical
+irrelevance.
+
+
+Precision
+---------
+
+Of course, this would be pointless if the annotation did not give
+precise enough information for our needs.  We must describe a detail of
+the abstract interpretation engine that is critical for precision: the
+propagation of conditional types.  Consider the following source code
+fragment::
+
+    if isinstance(x, MyClass):
+        f(x)
+    else:
+        g(x)
+
+Although the type of ``x`` may be some parent class of ``MyClass``, it
+can be deduced to be of the more precise type ``Inst(MyClass)`` within
+the positive branch of the ``if``.  (Remember that our graphs are in SSI
+form, which means that the ``x`` inside each basic block is a different
+Variable with a possibly different type as annotation.)
+
+This is implemented by introducing an extended family of types for
+boolean values::
+
+    Bool(v_1: (t_1, f_1), v_2: (t_2, f_2), ...)
+
+where the *v_n* are variables and *t_n* and *f_n* are types.  The result
+of a check, like ``isintance()`` above, is typically annotated with such
+an extended ``Bool``.  The meaning of the type is as follows: if the
+run-time value of the boolean is True, then we know that each variable
+*v_n* has a type at most as general as *t_n*; and if the boolean is
+False, then each variable *v_n* has a type at most as general as *f_n*.
+This information is propagated from the check operation to the exit of
+the block via such an extended ``Bool`` type, and the conditional exit
+logic in the type inference engine uses it to trim the types it
+propagates into the next blocks (this is where the *meet* of the lattice
+is used).
+
+With the help of the above technique, we achieve a reasonable precision
+in small examples.  For larger examples, a different, non-local
+technique is required: the specialization of functions.
+
+As described in the introduction, the most important downside of our
+approach is that automatic specialization is a potential
+performance-killer.  We *do* support specialization, however: we can
+generate several independently-annotated copies of the flow graphs of
+certain functions.  When annotating RPython programs, such
+specialization does not happen automatically: we rely on hints provided
+by the programmer in the source code, in the form of flags attached to
+function objects.  As we had this trade-off in mind when we wrote the
+Python interpreter of PyPy, we only had to add a dozen or so hints in
+the end.
+
+This does not mean that automatic specialization policies are difficult
+to implement.  Indeed, the simpler lower-level type systems rely quite
+heavily on them: this is because the system code helpers are often
+generic and can receive arguments of various C-level types.  In this
+case, because the types at this level are limited and mostly unordered,
+specializing all functions on their input argument's types works well.
+
+At the level of RPython, on the other hand, the range of specializations
+that make sense is much wider.  We have used anything between
+specialization by the type of an argument, to specialization by an
+expected-to-be-constant argument value, to memoized functions that the
+type inference engine will actually call during annotation and replace
+by look-up tables, to complete overriding of the annotator's behavior in
+extreme cases.  In this sense, the need for manual specialization turned
+into an advantage, in term of simplicity and flexibility of implementing
+and using new specialization schemes.
+
+This conclusion can be generalized.  We experimented with a simple
+approach to type inference that works well in practice, and that can
+very flexibly accomodate changes in the type system and even completely
+different type systems.  We think that the reasons for this success are
+to be found on the one hand in the (reasonable) restrictions we put on
+ourselves when designing the RPython language and writing the Python
+interpreter of PyPy in RPython, and on the other hand in an ad-hoc type
+system that is designed to produce enough precision (but not more) for
+the purpose of the subsequent transformations to C-level code.
+
+We should mention that restricting oneself to write RPython code instead
+of Python is still a burden, and that we are not proposing in any way
+that the Python language itself should evolve in this direction, nor
+even that RPython usage should become widespread.  It is a tool designed
+with a specific goal in mind, which is the ability to produce reasonably
+efficient, stand-alone code in a large variety of environment.

+------------------------------
+
+- thursday evening: a beer meeting point is 8pm "hotel an der uni"
+- friday morning: meeting point and time will be posted by Armin 
+  holger will also try to get information. 
+- monday is likely the breakday 
+- armin may only arrive on the 4th 
+
+- release day is set as the 7th, Wednesday 
+
+DLS paper 
+----------------
+
+The work on this is well in progress, says Armin.  But he
+needs two days of work with Samuele on some specific sections. 
+Michael offers to review wednesday afternoon. 
+
+Also, some LateX fighting is foreseen, help would

+
+EP pre and post sprint
+-------------------------------
+
+We decided to go for the full 6th-9th (both including) as the
+post-EP sprint time.  Sprint is scheduled in Geneva.
+Announcement pending. 
+
+pre-EP sprint: it is not clear yet who could come and focus on
+the core sprint.  Carl, Michael and possibly Holger will not
+be able to attend.  Niklaus, Christian, Armin, Anders and Arre
+could attend. 
+
+We'll decide in DDorf about the pre-EP sprint
+and its location (Geneva or Leysin). 
+
+Misc topics
+-------------
+
+Michael and holger will care tomorrow for co-ordinating/doing
+the pypy talk EuroPython 2006 submissions.

+    May 29 17:17:27 	he probably has a good pointer 
+    May 29 17:17:39 	i'll CC you so you can repost/enrich and send to pypy-sprint 
+    May 29 17:17:42 	i expect so
+    May 29 17:17:47 	and hopefully no weak ref
+    May 29 17:17:51 	next topic: DLS paper 
+    May 29 17:18:01 	what is the status? 
+    May 29 17:18:23 	(DLS = dynamic language symposium, deadline 30 or 31st may)
+    May 29 17:18:25 	it seems to be about 50% done?
+    May 29 17:18:31 	deadline is june 1
+    May 29 17:18:35 	including? 
+    May 29 17:18:40 	I think the meat of the text is done
+    May 29 17:18:46 	http://www.dcl.hpi.uni-potsdam.de/dls2006/openconf.php
+    May 29 17:19:02 	hpk: don't know, but as everyone is traveling on the 1st...
+    May 29 17:19:14 	except armin maybe :) 
+    May 29 17:19:22 	31st becomes the actual deadline indeed
+    May 29 17:19:43 	makes some sense
+    May 29 17:19:46 	this wednesday, uff
+    May 29 17:20:03 	i will try to read through the paper tomorrow
+    May 29 17:20:19 	then we can spend wednesday fighting with latex :/
+    May 29 17:20:20 	I definitely plan to work on it with Samuele for the whole next two days
+    May 29 17:20:25 	oh right
+    May 29 17:20:40 	hum, that includes the fighting with latex day, hopefully
+    May 29 17:21:15 *	stakkars needs to add a tiny topic to the very, just telling about personnell changes in tismerysoft
+    May 29 17:21:22 	very end
+    May 29 17:21:43 	so the DLS paper status is "in progress"
+    May 29 17:21:54 	arigo: ok, please scream if you need help for reviewing or even writing
+    May 29 17:21:54 	actively so, yes
+    May 29 17:22:14 	the more precise the scream the better :) 
+    May 29 17:22:27 	arigo: if it helps, I can make up some time on Wednesday
+    May 29 17:22:30 	what is left are the parts that only Samuele can really do right
+    May 29 17:22:37 	i see
+    May 29 17:22:44 	the references, related work etc.
+    May 29 17:23:04 	arigo: well, thanks a lot for taking up on this, btw
+    May 29 17:23:47 	one thing: i saw that hardly anyone assigned 0.9 issues to himself, it would really be helpful if we could distribute the efforts, also before the sprint 
+    May 29 17:24:27 	how about going through the list on Thursday evning, together?
+    May 29 17:24:46 	might make sense, yes, or friday morning, where we need a planning session anyway
+    May 29 17:24:56 	thursday evening not everybody will be there 
+    May 29 17:25:12 	but enough to get 80% off the kist
+    May 29 17:25:15 	list
+    May 29 17:25:21 	mwh: how much are EP deadlines interfering with our sprint timing? 
+    May 29 17:25:41 	well, the submission deadline for talks is the 31st
+    May 29 17:25:52 	*gulp*
+    May 29 17:26:05 	mwh: sure but i mean the sprint itself 
+    May 29 17:26:10 	so it would be nice to get a preliminary timetable up by the 4th or so
+    May 29 17:26:16 	mwh: but we indeed need to submit our talks that we discussed about last time 
+    May 29 17:26:22 	we need to get some pypy talk submissions in
+    May 29 17:26:24 	yes, indeed
+    May 29 17:26:33 	before the sprint...
+    May 29 17:26:45 	i put a small summary of the ideas into extradoc
+    May 29 17:26:56 	mwh: shall we co-ordinate tomorrow on #pypy regarding the talk submissions and see how we get them done? 
+    May 29 17:26:58 	we need to decide who gives what talk
+    May 29 17:27:01 	hpk: ok
+    May 29 17:27:10 	mwh: yes
+    May 29 17:27:18 	tomorrow then
+    May 29 17:27:39 	ok, last topic
+    May 29 17:27:43 	hpk: can you explain your pre-ep sprint mail then, you seem to have confused armin and me at least :)
+    May 29 17:27:57 	me 2
+    May 29 17:28:08 	mwh: you answered "you had similar thoughts", didn't you? 
+    May 29 17:28:41 	well, yes, but i'm not sure what you were in fact proposing
+    May 29 17:28:44 	let's simply ask: who would come to a four-day pre-EP sprint and promise to 90% focus on pypy core and not on anything EP related? 
+    May 29 17:29:03 	i think i want to be in geneva well before the conference
+    May 29 17:29:13 	i don't think i could reasonably sprint in leysin say
+    May 29 17:29:20 	i know that Carl can't either 
+    May 29 17:29:29 	this doesn't apply to everyone else so much necessarily!
+    May 29 17:29:46 	and i personally doubt that anyone would have the focus we had last time in leysin (where we convened for almost 7 days, without many distractions!)
+    May 29 17:29:51 	speaking for myself, Leysin would be preferable
+    May 29 17:30:34 	I dont have anything to do concerning EP
+    May 29 17:30:44 	anyway, let's close the official meeting (apart from christian's point) and decide in Duesseldorf about pre-EP
+
+    May 29 17:30:52 	for what it's worth, i could come to a pre-EP sprint (but not the post-EP one). i'd prefer geneva.
+    May 29 17:31:12 *	hpk is not out to block it, just trying to realistically make a guess about how effective it would be
+    May 29 17:31:14 	I think to come to whatsoever
+    May 29 17:31:31 	shortly to my point?
+    May 29 17:31:47 	sure
+    May 29 17:32:17 	1. Gerald has resigned from tismerysoft, backward by the end of March.
+    May 29 17:32:44 	2. Eric is leaving the company on his own behalf by end of June.
+    May 29 17:33:12 	3. I'm trying to get Richard back into more PyPy work by motivating EWT. This is in progress.
+    May 29 17:33:14 	EOF
+    May 29 17:33:24 	Pre- and/or post- is not problem for me.
+    May 29 17:33:43 	the post-EP one is not in question 
+    May 29 17:34:23 	side note: EWT people are coming to EP, and might consider to join a sprint if they are welcome.
+    May 29 17:34:30 	stakkars: i see, thanks for letting us know 
+    May 29 17:34:49 *	stakkars is actually sad about 1/2 but well
+    May 29 17:35:09 	i imagine 
+    May 29 17:36:20 	nikh: good to know, that you'd come to pre-ep :) 
+    May 29 17:36:24 	any other business?
+    May 29 17:36:25 	can we decide now that the post-EP sprint from 6th to 9th in Geneva will occur?
+    May 29 17:36:56 	sure, it think it's clear that we do a post-ep, question is how long 
+    May 29 17:37:00 	the situation seems confused enough that I think we should clarify this now, if possible
+    May 29 17:37:15 	6th-9th are the official dates, I don't think it can easily be longer
+    May 29 17:37:30 	I think so, yes
+    May 29 17:37:30 	arigo: sounds good to me
+    May 29 17:37:33 	ok, then let's go for that 
+    May 29 17:37:46 	9th including (to not loose another of those few days)
+    May 29 17:37:53 	yes
+    May 29 17:38:07 	so people should usually stay until 10th, unless they only have a short trip
+    May 29 17:38:41 	makes sense
+    May 29 17:38:46 	ok, this is set, then if nobody objects (/me notes that he is not sure about his full post-EP attendance yet)
+    May 29 17:39:07 	not sure about what?
+    May 29 17:39:16 	not sure about coming the full post-ep time myself 
+    May 29 17:39:16 	ah, your attendance
+    May 29 17:39:19 	right
+    May 29 17:39:43 *	hpk redundantly sidenotes that he'd like to get to some project planning regarding the rest of the year, including sprints
+    May 29 17:39:47 	my auto-detypo-filter made me read "this" :-)
+    May 29 17:40:15 	hpk: i guess ddorf is a good place for that
+    May 29 17:41:15 	yip
+    May 29 17:41:37 	(the meeting is closed, in case nobody noticed yet :)
+    May 29 17:42:01 	bye
+    May 29 17:42:05 	ok, bye then ;)
+    May 29 17:42:11 	bye!
+    May 29 17:42:14 	bye 
+    May 29 17:42:17 	bye

Log:
- Added some passing test
- Added basic class support (without inheritance)
- Several bugfixes
- Added constant support (list, string, instance, primitive, no dict yet)
- Added basic builtin functions and methods mapping (altough I'm not particurarly happy with this solution)
- Added some new opcodes, mostly ootypesystem related

+Our tool-chain is capable of translating the Python interpreter of PyPy,
+written in RPython, producing right now ANSI C code as described before,
+and also LLVM [#]_ assembler then natively compiled with LLVM tools  
+
+.. [#] the LLVM project is the realisation of a portable assembler
+       infrastructure, offering both a virtual machine with JIT
+       capabilities and static compilation. Currently we are using
+       the latter with its good high-level optimisations for PyPy.
+
+The tool-chain has been tested and can sucessfully apply
+transformations enabling various combinations of features. The
+translated interpreters are benchmarked using pystone (a Dhrystone_
+derivative traditionally used by the Python community, although is a
+rather poor benchmark) and the classical Richards_ benchmark and
+compared against CPython_ 2.4.3 results:

+Applying the expressiveness or at least syntax of very high-level and
+dynamically typed languages to their implementation has been
+investigated many times. 
+
+One typical approach is writing a static compiler.  The viability of
+and effort required for such an approach depend usually on the binding
+and dispatch semantics of the language.  Common Lisp native compilers,
+usable interactively and taking functions or files as compilation
+units are a well-known example of that approach.  Late binding for all
+names and load semantics make such an approach very hard for Python,
+if speed improvements are desired.
+
+It is more relevant to consider and compare with projects using
+dynamic and very-high level languages for interpreters and VM
+implementations, and Just-In-Time compilers.
+
+Scheme48_ was a Scheme implementation using a restricted Scheme, with
+static type inference based on Hindley-Milner, this is viable for
+Scheme as base language. Portability and simplicity were its major
+goals.
+
+Squeak_ is a Smalltalk implementation in Smalltalk. It uses SLang, a
+very restricted subset of Smalltalk with few types and strict
+conventions such that mostly direct translation to C is possible.
+Both the VM and the object memory and garbage collector support are
+explicitly written together in this style. Again simplicity and
+portability were the major goals, not sophisticated manipulation and
+analysis and waving in of features.

+The numbers in parenthesis are slow-down factors compared to CPython.
+These measures reflect PyPy revision 27815, compiled with GCC 3.4.4.
+LLVM is version 1.8cvs (May 11, 2006).  The machine runs GNU/Linux SMP
+on an Intel(R) Pentium(R) 4 CPU at 3.20GHz with 2GB of RAM and 1MB of
+cache.  The rows correspond to variants of the translation process, as
+follows:
+
+pypy-c
+    The simplest variant: translated to C code with no explicit memory
+    management, and linked with the Boehm conservative GC `[Boehm]`_.
+
+pypy-c-thread
+    The same, with OS thread support enabled.  (For measurement purposes,
+    thread support is kept separate because it has an impact on the GC
+    performance.)
+
+pypy-c-stackless
+    The same as pypy-c, plus the "stackless transformation" step which
+    modifies the flow graph of all functions in a way that allows them
+    to save and restore their local state, as a way to enable coroutines.
+
+pypy-c-gcframework
+    In this variant, the "gc transformation" step inserts explicit
+    memory management and a simple mark-and-sweep GC implementation.
+    The resulting program is not linked with Boehm.  Note that it is not
+    possible to find all roots from the C stack in portable C; instead,
+    in this variant each function explicitly pushes and pops all roots
+    to an alternate stack around each subcall.
+
+pypy-c-stackless-gcframework
+    This variant combines the "gc transformation" step with the
+    "stackless transformation" step.  The overhead introduced by the
+    stackless feature is balanced with the removal of the overhead of
+    pushing and popping roots explicitly on an alternate stack: indeed,
+    in this variant it is possible to ask the functions in the current C
+    call chain to save their local state and return.  This has the
+    side-effect of moving all roots to the heap, where the GC can find
+    them.
+
+pypy-llvm-c
+    The same as pypy-c, but using the LLVM back-end instead of the C
+    back-end.  The LLVM assembler-compiler gives the best results when -
+    as we do here - it optimizes its input and generates again C code,
+    which is fed to GCC.
+
+pypy-llvm-c-prof
+    The same as pypy-llvm-c, but using GCC's profile-driven
+    optimizations.
+
+XXX explain slow.
+
+The complete translation of the pypy-c variant takes about 39 minutes,
+divided as follows:

+
+An interesting feature of this table is that type inference is not the
+bottleneck.  Indeed, further transformation steps typically take longer
+than type inference alone.  This is the case for the LLTyper step,
+although it has a linear complexity on the size of its input (most
+transformations do).
+
+Other transformations like the "gc" and the "stackless" ones actually
+take more time, particuarly when used in combination with each other (we
+speculate it is because of the increase in size caused by the previous
+transformations).  A translation of pypy-c-stackless, without counting
+GCC time, takes 60 minutes; the same for pypy-c-stackless-gcframework
+takes XXX minutes.

+Jikes RVM native JIT compilers can likely not easily be retargeted to
+run on top and target another VM (for example a CLR runtime) instead
+of hardware processors. Also Jikes RVM pays the complexity of writing
+a JIT up-front, which also means that features and semantics of the
+language are encoded in the JIT compiler code, meaning likely that
+major changes would correspond to major surgery needed on it.
+
+PyPy more indirect approach, together hopefully with our future work
+on generating a JIT compiler, tries to overcome these limitations, at
+the price of some more effort required to achieve very good
+performance. It is too soon to compare completely the complexity (and
+performance) trade-offs of these approaches.

-XXX explain slow.
+The speed difference with CPython 2.4.3 can be explained at two levels.
+One is that CPython is hand-crafted C code that has been continuously
+optimized for a decade now, whereas the Python interpreter of PyPy first
+seeks flexibility and high abstraction levels.  The other, probably
+dominant, factor is that various indices show that our approach places a
+very high load on the GC and on the memory caches of the machine.  The
+Boehm GC is known to be less efficient than more customized approach;
+kernel-level profiling shows that pypy-c typically spends 30% of its
+time in the Boehm library.  Our current, naively simple mark-and-sweep
+GC is even quite worse.  The interaction with processor caches is also
+hard to predict and account for; in general, we tend to produce
+relatively large amounts of code and prebuilt data.

+As described in `section 5`_, the performance of the compiled Python
+interpreters is still not up to competing with the well-established
+CPython.  We are always working to improve matters, considering new
+optimizations and better GCs.  Also, the OOTyper and back-ends for
+Smalltalk/Squeak and CLI/.NET are currently in progress.
+
+
+JIT Specializer
+---------------
+
+So far, the PyPy tool-chain can only translate the Python interpreter of
+PyPy into a program which is again an interpreter - the same interpreter
+translated to C, essentially, although we have already shown that some
+aspects can be "weaved" in at translation time, like support for
+coroutines.
+
+To achieve high performance for dynamic languages such as Python, the
+proven approach is to use dynamic compilation techniques, i.e. to write
+JITs.  With direct techniques, this is however a major endeavour, and
+increases the efforts to further evolve the language.
+
+In the context of the PyPy project, we are now exploring - as we planned
+from the start - the possibility to produce a JIT as a graph
+transformation aspect from the Python interpreter.  This idea is based
+on the theoretical possibiliy to turn interpreters into compilers by
+partial evaluation `[PE]`_.  In our approach, this is done by analysing
+the forest of flow graphs built from the Python interpreter, which is a
+well-suited input for this kind of techniques.  We can currently perform
+binding-time analysis `[BTA]`_ on these graphs, again with abstract
+interpretation techniques reusing the type inference engine.  The next
+step is to transform the graphs - following the binding-time annotations
+- into a compiler; more precisely, in partial evalution terminology, a
+generating extension.  We can currently do this on trivial examples.
+
+The resulting generating extension will be essentially similar to
+Psyco_, which is the only (and hand-written) JIT available for Python so
+far, based on run-time specialization.

+% ACM_PROC_ARTICLE-SP  DOCUMENT STYLE
+% G.K.M. Tobin August-October 1999

+% ARTICLE DOCUMENT STYLE -- Released 16 March 1988
+%    for LaTeX version 2.09
+% Copyright (C) 1988 by Leslie Lamport
+%
+%
+%%% ACM_PROC_ARTICLE-SP is a document style for producing two-column camera-ready pages for
+%%% ACM conferences, according to ACM specifications.  The main features of
+%%% this style are:
+%%%
+%%% 1)  Two columns.
+%%% 2)  Side and top margins of 4.5pc, bottom margin of 6pc, column gutter of
+%%%     2pc, hence columns are 20pc wide and 55.5pc tall.  (6pc =3D 1in, approx)
+%%% 3)  First page has title information, and an extra 6pc of space at the
+%%%     bottom of the first column for the ACM copyright notice.
+%%% 4)  Text is 9pt on 10pt baselines; titles (except main) are 9pt bold.
+%%%
+%%%
+%%% There are a few restrictions you must observe:
+%%%
+%%% 1)  You cannot change the font size; ACM wants you to use 9pt.
+%%% 3)  You must start your paper with the \maketitle command.  Prior to the
+%%%     \maketitle you must have \title and \author commands.  If you have a
+%%%     \date command it will be ignored; no date appears on the paper, since
+%%%     the proceedings will have a date on the front cover.
+%%% 4)  Marginal paragraphs, tables of contents, lists of figures and tables,
+%%%     and page headings are all forbidden.
+%%% 5)  The `figure' environment will produce a figure one column wide; if you
+%%%     want one that is two columns wide, use `figure*'.
+%%%
+%
+%%% Copyright Space:
+%%% This style automatically leaves 1" blank space at the bottom of page 1/
+%%% column 1.  This space can optionally be filled with some text using the
+%%% \toappear{...} command.  If used, this command must be BEFORE the \maketitle
+%%% command.  If this command is defined AND [preprint] is on, then the
+%%% space is filled with the {...} text (at the bottom); otherwise, it is
+%%% blank.  If you use \toappearbox{...} instead of \toappear{...} then a
+%%% box will be drawn around the text (if [preprint] is on).
+%%%
+%%% A typical usage looks like this:
+%%%     \toappear{To appear in the Ninth AES Conference on Medievil Lithuanian
+%%%               Embalming Technique, June 1991, Alfaretta, Georgia.}
+%%% This will be included in the preprint, and left out of the conference
+%%% version.
+%%%
+%%% WARNING:
+%%% Some dvi-ps converters heuristically allow chars to drift from their
+%%% true positions a few pixels. This may be noticeable with the 9pt sans-serif
+%%% bold font used for section headers.
+%%% You may turn this hackery off via the -e option:
+%%%     dvips -e 0 foo.dvi >foo.ps
+%%%

+% Rationale for changes made in next four definitions:
+% "Before skip" is made elastic to provide some give in setting columns (vs.
+% parskip, which is non-elastic to keep section headers "anchored" to their
+% subsequent text.
+%
+% "After skip" is minimized -- BUT setting it to 0pt resulted in run-in heads, despite
+% the documentation asserted only after-skip < 0pt would have result.
+%
+% Baselineskip added to style to ensure multi-line section titles, and section heads
+% followed by another section head rather than text, are decently spaced vertically.

-nice interpreter not polluted by implementation details

-architecture allows implementing features at the right level

-dynamic language enables defining our own various type systems
-[ref pluggable type systems]
-
-practical VMs will result with a bit more efforts
-
+The PyPy project aims at showing that dynamic languages are suitable and
+quite useful for writing virtual machines in.  We believe that we have
+achieved this objective.  The present paper gave an overview of the
+architecture that enabled this result.  Experiments suggest that
+practical virtual machines could reasonably follow in the near future,
+with faster-than-current virtual machines with JIT specialization
+techniques for the mid-term future.
+
+Targetting platforms that are very different from C/Posix is work in
+progress, but given that many of the initial components are shared with
+the existing stack of transformations leading to C, we are confident
+that this work will soon give results.  Moreover, we believe that these
+results will show a reasonable efficiency, because the back-ends for VMs
+like Squeak and .NET can take advantage of high-level input (as opposed
+to trying to translate, say, C-like code to Smalltalk).
+
+A desirable property of our approach is to allow a given language and VM
+to be specified only once, in the form of an interpreter.  Moreover, the
+interpreter can be kept simple (and thus keep its role as a
+specification): not only is it written in a high-level language, but it
+is not overloaded with low-level design choices and implementation
+details.  This makes language evolution and experimentation easier.
+More generally, this property is important because many interpreters for
+very difference languages can be written: the simpler these interpreters
+can be kept, the more we win from our investment in writing the
+tool-chain itself - a one-time effort.
+
+Dynamic languages enable the definition of multiple custom type systems,
+similar to *pluggable type systems* in Bracha_.  This proved a key
+feature in implementing our translation tool-chain, because it makes a
+many-levels approach convenient: each abstraction level can provide an
+implementation for some of the features that the higher levels
+considered primitive.  It offsets the need to define a minimal kernel of
+primitives and build everything on top of it; instead, we have been able
+to implement, so to speak, the right feature at the right level.

+% title ideas: Implementing Virtual Machines in Dynamic Languages?
+
+\maketitle
+
+\begin{abstract}
+The PyPy project seeks to prove both on a research and a
+practical level the feasibility of writing a virtual machine (VM)
+for a dynamic language in a dynamic language -- in this case, Python.
+The aim is to translate (i.e. compile) the VM to arbitrary target
+environments, ranging in level from C/Posix to Smalltalk/Squeak via
+Java and CLI/.NET, while still being of reasonable efficiency within
+these environments.
+
+A key tool to achieve this goal is the systematic reuse of the
+(unmodified, dynamically typed) Python language as a system
+programming language at various levels of our architecture and
+translation process.  For each level, we design a corresponding type
+system and apply a generic type inference engine -- for example, the
+garbage collector is written in a style that manipulates
+simulated pointer and address objects, and when translated to C
+these operations become C-level pointer and address instructions.
+\end{abstract}
+
+\section{Introduction}
+
+Despite the constant trend in the programming world towards
+portability and reusability, there are some areas in which it is still
+notoriously difficult to write flexible, portable, and reasonably
+efficient programs.  The implementation of virtual machines is one
+such area.  Building implementations of general programming languages,
+in particular highly dynamic ones, using a classic direct coding
+approach, is typically a long-winded effort and produces a result that
+is quite [quite could be removed here?] tailored to a specific
+platform and where architectural decisions (e.g. about GC) are spread
+across the code in a pervasive and invasive way.
+
+For this and other reasons, standard platforms emerge; nowadays, a
+language implementer could cover most general platforms in use by
+writing three versions of his virtual machine: for C/Posix, for Java,
+and for CLI/.NET.  This is, at least, the current situation of the
+Python programming language, where independent volunteers have
+developed and are now maintaining Java and .NET versions of Python,
+which follow the evolution of the "official" C version (CPython).
+
+However, we believe that platform standardization does not have to be
+a necessary component of this equation.  We are basically using the
+standard "meta-programming" argument: if one could write the VM in a
+very high level language, then the VM itself could be automatically
+\textit{translated} to any lower-level platform.  Moreover by writing
+the VM in such a language we would gain in flexibility in
+architectural choices and expressiveness.
+
+PyPy achieves this goal without giving up on the efficiency of the
+compiled VMs.  
+
+The key factors enabling this result are not to be found in recent
+advances in any particular research area -- we are not for example using
+constraint-based type inference.  Instead, we are following a novel
+overall architecture: it is split into many levels of stepwise
+translation from the high-level source of the VM to the final target
+platform.  Similar platforms can reuse many of these steps, while for
+very different platforms we have the option to perform very different
+translation steps.  Each step reuses a common type inference component
+with a different, ad-hoc type system.
+
+Experiments also suggest a more mundane reason why such an approach is
+only practical today: a typical translation takes about half an hour
+on a modern PC and consumes between 512MB and 1GB of RAM.
+
+We shortly describe the architecture of PyPy in section
+\ref{architecture}.  In section \ref{systemprog} we describe our
+approach of varying the type systems at various levels of the
+translation.  Section \ref{typeinference} gives an overview of the
+type inference engine we developed (and can be read independently from
+section 3.)  We present experimental results in section
+\ref{experimentalresults} and future work directions in section
+\ref{futurework}.  In section \ref{relatedwork} we compare with
+related work, and finally we conclude in section \ref{conclusion}.
+
+\section{Architecture}
+\label{architecture}
+
+There are two major components in PyPy:
+
+\begin{enumerate}
+\item the \textit{Standard Interpreter}: an implementation of the Python programming
+language, mostly complete and compliant with the current version of the
+language, Python 2.4.
+\item the \textit{Translation Process}: a translation tool-suite whose goal is to
+compile subsets of Python to various environment.
+\end{enumerate}
+
+In particular, we have defined a subset of the Python language called
+"restricted Python" or RPython.  This sublanguage is not restricted
+syntactically, but only in the way it manipulates objects of different
+types.  The restrictions are a compromise between the expressivity and
+the need to statically infer enough types to generate efficient code.
+The foremost purpose of the translation tool-suite is to compile such
+RPython programs to a variety of different platforms.
+
+Our current efforts, and the present paper, focus on this tool-suite.
+We will not describe the Standard Interpreter component of PyPy in the
+sequel, other than mention that it is written in RPython and can thus be
+translated.  At close to 90,000 lines of code, it is the largest RPython
+program that we have translated so far.  More information can be found
+in [S].
+
+
+\section{System programming with Python}
+\label{systemprog}
+
+\hypertarget{the-translation-process}{}
+\subsection{The translation process}
+\label{translationprocess}
+
+The translation process starts from RPython source code and eventually
+produces low-level code suitable for the target environment.  It can be
+described as performing a series of step-wise transformations.  Each
+step is based on control flow graph transformations and rewriting, and
+on the ability to augment the program with further implementation code
+written in Python and analysed with the suitable type system.
+
+The front-end part of the translation process analyses the input
+RPython program in two phases, as follows\footnote{Note that the two
+phases are intermingled in time, because type inference proceeds from
+an entry point function and follows all calls, and thus only gradually
+discovers (the reachable parts of) the input program.}:

+\begin{enumerate}
+\item We take as input RPython functions\footnote{The input to our

+       not source code or ASTs.  This allows us to use unrestricted
+       python for meta-programming purposes at load time, in a
+       seemingly staged programming approach, in which the whole of
+       the source program -- as Python program -- produces the RPython
+       program input to the tool-chain as the object graph loaded in
+       memory.  This includes both the relevant functions and prebuilt
+       data.}, and convert them to control flow graphs -- a structure
+       amenable to analysis.  These flow graphs contain polymorphic
+       operations only: in Python, almost all operations are
+       dynamically overloaded by type.
+
+\item We perform type inference on the control flow graphs.  At this
+      stage, types inferred are part of the type system which is the
+      very definition of the RPython sub-language: they are roughly a
+      subset of Python's built-in types, with some more precision to
+      describe e.g. the items stored in container types.
+      Occasionally, a single input function can produce several
+      specialized versions, i.e. several similar but differently typed
+      graphs.  This type inference process is described in more
+      details in section \ref{typeinference}.
+\end{enumerate}
+      
+At the end of the front-end analysis, the input RPython program is
+represented as a forest of flow graphs with typed variables.  Following
+this analysis are a number of transformation steps.  Each transformation
+step modifies the graphs in-place, by altering their structure and/or
+the operations they contain.  Each step inputs graphs typed in one type
+system and leaves them typed in a possibly different type system, as we
+will describe in the sequel.  Finally, a back-end turns the resulting
+graphs into code suitable for the target environment, e.g. C source code
+ready to be compiled.
+
+
+\subsection{Transformations}
+
+When the translation target is C or C-like environments, the first of
+the transformation steps takes the RPython-typed flow graphs, still
+containing polymorphic operations only, and produces flow graphs with
+monomorphic C-like operations and C-like types.  In the simplest case,
+this is the only transformation step: these graphs are directly fed to
+the C back-end, which turns them into ANSI C source code.
+
+But RPython comes with automatic memory management, and this first
+transformation step produces flow graphs that also assume automatic
+memory management.  Generating C code directly from there produces a
+fully leaking program, unless we link it with an external garbage
+collector (GC) like the Boehm conservative GC [Boehm], which is a
+viable option.
+
+We have two alternatives, each implemented as a transformation step.
+The first one inserts naive reference counting throughout the whole
+program's graphs, which without further optimizations gives exceedingly
+bad performance (it should be noted that the CPython interpreter is also
+based on reference counting, and experience suggests that it was not a
+bad choice in this particular case).
+
+The other, and better, alternative is an exact GC, coupled with a
+transformation, the \textit{GC transformer}.  It inputs C-level-typed graphs
+and replaces all \texttt{malloc} operations with calls to a garbage
+collector's innards.  It can inspect all the graphs to discover the
+\texttt{struct} types in use by the program, and assign a unique type id to
+each of them.  These type ids are collected in internal tables that
+describe the layout of the structures, e.g. their sizes and the location
+of the pointer fields.
+
+We have implemented other transformations as well, e.g. performing
+various optimizations, or turning the whole code into a
+continuation-passing style (CPS) [I'm not sure our transformation
+can be classified as classical CPS, although there are known similar techniques but the terminology is quite confused] that allows us to use coroutines
+without giving up the ability to generate fully ANSI C code.  (This will
+be the subject of another paper.)  [mention exception transformer too]
+
+Finally, currently under development is a variant of the very first
+transformation step, for use when targeting higher-level,
+object-oriented (OO) environments.  It is currently being designed
+together with back-ends for Smalltalk/Squeak\footnote{Our simple OO
+type system is designed for \textit{statically-typed} OO environments,
+including Java; the presence of Smalltalk as a back-end might be
+misleading in that respect.} and CLI/.NET.  This first transformation
+step, for C-like environments, is called the \textit{LLTyper}: it produces
+C-level flow graphs, where the object-oriented features of RPython
+(classes and instances) become manipulations of C structs with
+explicit virtual table pointers.  By contrast, for OO environments the
+transformation step is called the \textit{OOTyper}: it targets a simple
+object-oriented type system, and preserves the classes and instances
+of the original RPython program.  The LLTyper and OOTyper still have
+much code in common, to convert the more Python-specific features like
+its complex calling conventions.
+
+More information about these transformations can be found in [T].
+
+
+\subsection{System code}
+
+A common pattern in all the transformation steps is to somehow lower the
+level at which the graphs are currently expressed.  Because of this,
+there are operations that were atomic in the input (higher-level) graphs
+but that need to be decomposed into several operations in the target
+(lower-level) graphs.  In some cases, the equivalent functionality
+requires more than a couple of operations: a single operation must be
+replaced by a call to whole new code -- functions and classes that serve
+as helpers.  An example of this is the \texttt{malloc} operation for the GC
+transformer.  Another example is the \texttt{list.append()} method, which is
+atomic for Python or RPython programs, but needs to be replaced in
+C-level code by a helper that possibly reallocates the array of items.
+
+This means that in addition to transforming the existing graphs, each
+transformation step also needs to insert new functions into the forest.
+A key feature of our approach is that we can write such "system-level"
+code -- relevant only to a particular transformation -- in plain Python
+as well:
+
+\begin{verbatim}
+.. topic:: Figure 1 - a helper to implement \texttt{list.append()}
+
+  ::
+
+    def ll_append(lst, newitem):
+        # Append an item to the end of the vector.
+        index = lst.length         # get the 'length' field
+        ll_resize(lst, index+1)    # call a helper not shown here
+        itemsarray = lst.items     # get the 'items' field
+        itemsarray[index] = item   # this behaves like a C array
+\end{verbatim}
+
+The idea is to feed these new Python functions into the front-end, using
+this time the transformation's target (lower-level) type system during
+the type inference.  In other words, we can write plain Python code that
+manipulates objects that conform to the lower-level type system, and
+have these functions automatically transformed into appropriately typed
+graphs.
+
+For example, \texttt{ll\textunderscore{}append()} in figure 1 is a Python function
+that manipulates objects that behave like C structures and arrays.
+This function is inserted by the LLTyper, as a helper to implement the
+\texttt{list.append()} calls found in its RPython-level input graphs.
+By going through the front-end reconfigured to use C-level types, the
+above function becomes a graph with such C-level types\footnote{The
+low-level type system specifies that the function should be
+specialized by the C-level type of its input arguments, so it actually
+turns into one graph per list type -- list of integers, list of
+pointers, etc.  This behavior gives the programmer a feeling
+comparable to C++ templates, without the declarations.}, which is then
+indistinguishable from the other graphs of the forest produced by the
+LLTyper.
+
+In the example of the \texttt{malloc} operation, replaced by a call to GC
+code, this GC code can invoke a complete collection of dead objects, and
+can thus be arbitrarily complicated.  Still, our GC code is entirely
+written in plain Python, and it manipulates "objects" that are still at
+a lower level: pointer and address objects.  Even with the restriction
+of having to use pointer-like and address-like objects, Python remains
+more expressive than, say, C to write a GC.  [see also Jikes]
+
+In the sequel, we will call \textit{system code} functions written in
+Python that are meant to be analysed by the front-end.  For the
+purpose of this article we will restrict this definition to helpers
+introduced by transformations, as opposed to the original RPython
+program, although the difference is not fundamental to the translation
+process (and although our input RPython program, as seen in section
+\ref{architecture}, is often itself a Python virtual machine!).
+
+Note that such system code cannot typically be expressed as normal
+RPython functions, because it corresponds to primitive operations at
+that level.  As an aside, let us remark that the number of primitive
+operations at RPython level is, comparatively speaking, quite large:
+all list and dictionary operations, instance and class attribute
+accesses, many string processing methods, a good subset of all Python
+built-in functions...  Compared to other approaches [e.g. Squeak], we
+do not try to minimize the number of primitives -- at least not at the
+source level.  It is fine to have many primitives at any high enough
+level, because they can all be implemented at the next lower level in
+a way that makes sense to that level.  The key reason why this is not
+burdensome is that the lower level implementations are also written in
+Python -- with the only difference that they use (and have to be
+typeable in) the lower-level type system\footnote{This is not strictly
+true: the type systems are even allowed to co-exist in the same
+function.  The operations involving higher-level type systems are
+turned into lower-level operations by the previous transformations in
+the chain, which leave the already-low-level operations untouched.}.
+
+
+\subsection{Type systems}
+
+The four levels that we considered so far are summarized in figure 2.
+
+\begin{verbatim}
+::
+
+    [figure 2:    RPython
+                  /     \
+                 /       \
+       LLTypeSystem     OOTypeSystem
+               /
+              /
+      Raw addresses
+    ]
+\end{verbatim}
+
+The RPython level is a subset of Python, so the types mostly follow
+Python types, and the instances of these types are instances in the
+normal Python sense; e.g. whereas Python has only got a single type
+\texttt{list}, RPython has a parametric type \texttt{list(T)} for every RPython
+type \texttt{T}, but instances of \texttt{list(T)} are just those Python lists
+whose items are all instances of \texttt{T}.
+
+The other type systems, however, do not correspond to built-in Python
+types.  For each of them, we implemented:
+
+\begin{enumerate}
+\item the types, which we use to tag the variables of the graphs at
+      the given level.  (Types are actually annotated, self-recursive
+      formal terms, and would have been implemented simply as such if
+      Python supported them directly.)
+
+\item the Python objects that emulate instances of these types.  (More
+      about them below.)
+\end{enumerate}
+
+We have defined well-typed operations between variables of these types,
+plugging on the standard Python operators.  These operations are the
+ones that the emulating instances implement.  As seen above, the types
+can also be used by type inference when analysing system code like the
+helpers of figure 1.
+
+Now, clearly, the purpose of types like a "C-like struct" or a "C-like
+array" is to be translated to a real \texttt{struct} or array declaration by
+the C back-end.  What, then, is the purpose of emulating such things in
+Python?  The answer is three-fold.  Firstly, if we have objects that
+live within the Python interpreter, but faithfully emulate the behavior
+of their C equivalent while performing additional safety checks, they
+are an invaluable help for testing and debugging.  For example, we can
+check the correctness of our hash table implementation, written in
+Python in term of struct- and array-like objects, just by running it.
+The same holds for the GC.
+
+Secondly, and anecdotically, as the type inference process (section
+\ref{typeinference}) is based on abstract interpretation, we can use
+the following trick: the resulting type of most low-level operations
+is deduced simply by example.  Sample C-level objects are
+instantiated, used as arguments to a given operation, and produce a
+sample result, whose C-level type must be the type of the result
+variable in the graph.
+
+The third reason is fundamental: we use these emulating objects to
+\textit{represent} pre-built objects at that level.  For example, the GC
+transformer instantiates the objects emulating C arrays for the internal
+type id tables, and it fills them with the correct values.  These array
+objects are then either used directly when testing the GC, or translated
+by the C back-end into static pre-initialized arrays.
+
+
+
+\section{Type inference}
+\label{typeinference}
+
+
+The various analyses used -- from type inference to lifetime analysis -
+are generally formulated as [abstract interpretation].  While this
+approach is known to be less efficient than more tailored algorithms
+like constraint-based type inference, we gain in freedom,
+controllability and simplicity.  This proved essential in our overall
+approach: as described in section \ref{systemprog}, we need to perform
+type inference with many different type systems, the details of which
+have evolved along the road.
+
+We mitigate the potential efficiency problem by wise choices and
+compromises for the domain used; the foremost example of this is that
+our RPython type inference performs almost no automatic specialization
+of functions XXX class annotation vs concrete runtime class setsXXX.
+We achieved enough precision for our purpose, though.
+
+In the sequel, we give a more precise description of this process and
+justify our claim that good performance and enough precision can be
+achieved -- at least in some contexts -- without giving up the naive but
+flexible approach.
+
+
+\subsection{Building control flow graphs}
+\label{flowobjspace}
+\hypertarget{flowobjspace}{}
+
+As described in the overview of \href{\#the-translation-process}{the
+translation process}, the front-end of the translation tool-chain
+works in two phases: it first builds control flow graphs from Python
+functions, and then performs whole-program type inference on these
+graphs.
+
+Remember that building the control flow graphs is not done, as one might
+first expect, by following a function at the syntactic level.  Instead,
+the whole program is imported in a normal Python interpreter; the full
+Python language is used at this point as a kind of preprocessor with
+meta-programming capabilities.  Once the program is imported, the object
+data in memory consists of Python function objects in bytecode format,
+and any other kind of objects created at import-time, like class
+objects, prebuilt instances of those, prebuilt tables, and so on.  Note
+that these objects have typically no text representation any more; for
+example, cyclic data structures may have been built at this point.  The
+translation tool-chain first turns these function objects into in-memory
+control flow graphs which contain direct references to the prebuilt data
+objects, and then handles and transforms these graphs.
+
+We found in-process debugging sufficient and did not implement dumping
+of any intermediate step to disk.  Figure 3 shows the control flow graph
+obtained for a simple function -- this is a screenshot from our graph
+viewer, used for debugging; basic block placement is performed by
+[Graphviz].
+
+\begin{verbatim}
+::
+
+    [figure 3: insert a nice pygame screenshot]
+\end{verbatim}
+    
+The actual transformation from function objects -- i.e. bytecode -- to
+flow graph is performed by the Flow Object Space, a short but generic
+plug-in component for the Python interpreter of PyPy.  The architecture
+of our Python interpreter is shown in figure 4.
+
+\begin{verbatim}
+.. topic:: Figure 4 - the interpreter and object spaces
+
+    +------------------------------------------------------+
+    |   forest of bytecode objects from the application    |
+    +------------------------------------------------------+
+    |               Python bytecode interpreter            |
+    +--------------------------------+---------------------+
+    |      Standard Object Space     |  Flow Object Space  |
+    +--------------------------------+---------------------+
+\end{verbatim}
+
+Note that the left column, i.e. the bytecode interpreter and the
+Standard Object Space, form the full Python interpreter of PyPy.  It is
+an RPython program, and the whole purpose of the translation process is
+to accept this as \textit{input}, and translate it to an efficient form.  Its
+architecture is not relevant to the way it is translated. XXX?
+
+However, the bytecode interpreter plays a double role, at two different
+levels.  The so-called Object Spaces are \textit{domains} in the abstract
+interpretation terminology.  By design, we cleanly separated these
+domains from the bytecode interpreter core; the latter is only
+responsible for decoding the bytecodes of an application and emulating
+the corresponding stack machine.  It treats all actual application-level
+objects as black boxes, and dispatches all operations on them to the
+Object Space.  The Standard Object Space is a concrete domain, in which
+objects are the concrete Python objects of the various built-in types:
+lists, dictionaries, and so on.  By opposition, the Flow Object Space is
+really an abstract domain.  It handles objects that are placeholders.
+Its lattice order is shown in figure 5.
+
+\begin{verbatim}
+::
+
+    [figure 5:                Variable
+
+                         /      |             \           \
+                        /       |              \           \
+                       /        |               \           \
+      Constant(1) ... Constant(n) ... Constant([1,2,3])  ... Constant() ...
+    ]
+\end{verbatim}
+
+This order is extremely simple, because most actual analysis is delayed
+to the next phase, the type inference engine.  The objects are either
+\textit{Variables}, which are pure placeholders for entierely unknown values,
+or \textit{Constants} with a concrete Python object as value.  The order places
+Variable as the top, and keeps all \textit{Constants} unordered.  Thus if two
+different constants merge during abstract interpretation, we immediately
+widen them to Variable.
+
+In conjunction with the Flow Object Space, the bytecode interpreter of
+PyPy thus performs abstract interpretation of Python bytecodes from
+the application\footnote{Note that this process uses the
+\textit{unmodified} bytecode interpreter.  This means that it is
+independent of most language details.  Changes in syntax or in
+bytecode format or opcode semantics only need to be implemented once,
+in the bytecode interpreter.  In effect, the Flow Object Space enables
+an interpreter for \textit{any} language to work as a front-end for
+the rest of the tool-chain.}.  In this case, the bytecodes in
+question come from the RPython application that we would like to
+translate.
+
+The Flow Object Space records all operations that the bytecode
+interpreter "would like" to do between the placeholder objects.  It
+records them into basic block objects that will eventually be part of
+the control flow graph of the whole function.  The recorded operations
+take Variables and Constants as argument, and produce new Variables as
+results.  The Constants serve two purposes: they are a way to
+introduce constant values into the flow graphs -- these values may be
+arbitrarily complex objects, not just primitives -- and they allow
+basic constant propagation\footnote{This is useful at this level for
+some constructs of the bytecode interpreter, which can temporarily
+wrap internal values and push them onto the regular value stack among
+the other application-level objects.  We need to be able to unwrap
+them again later. XXX compile-time computation in the helpers.}
+
+In the flow graph, branching occurs when the bytecode interpreter tries
+to inspect the truth value of placeholder objects, as it would in
+response to conditional jump opcodes or other more complicated opcodes:
+at this point, the Flow Object Space starts two new basic blocks and -
+with a technique akin to continuations -- tricks the interpreter into
+following both branches, one after the other.  Additionally, the
+bytecode interpreter sends simple positional signals that allow the Flow
+Object Space to detect when control paths merge, or when loops close.
+In this way, abstract interpretation quickly terminates and the recorded
+operations form a graph, which is the control flow graph of the original
+bytecode.
+
+Note that we produce flow graphs in Static Single Information (SSI)
+form, an extension of Static Single Assignment ([SSA]): each variable is
+only used in exactly one basic block.  All variables that are not dead
+at the end of a basic block are explicitly carried over to the next
+block and renamed.
+
+While the Flow Object Space is quite a short piece of code -- its core
+functionality holds in 300 lines -- the detail of the interactions
+sketched above is not entierely straightforward; we refer the reader to
+[D] for more information.
+
+
+\subsection{The Annotator}
+
+The type inference engine, which we call the \textit{annotator}, is the central
+component of the front-end part of the translation process.  Given a
+program considered as a family of control flow graphs, the annotator
+assigns to each variable of each graph a so-called \textit{annotation}, which
+describes the possible run-time objects that this variable can contain.
+Following usual terminology, we will call such annotations \textit{types} -- not
+to be confused with the Python notion of the concrete type of an object.
+An annotation is a set of possible values, and such a set is not always
+the set of all objects of a specific Python type.
+
+Here is a simplified, static model of how the annotator works.  It can
+be considered as taking as input a finite family of functions calling
+each other, and working on the control flow graphs of each of these
+functions as built by the \href{flowobjspace}{Flow Object Space}.
+Additionally, for a particular "entry point" function, the annotator
+is provided with user-specified types for the function's arguments.
+
+The goal of the annotator is to find the most precise type that can be
+given to each variable of all control flow graphs while respecting the
+constraints imposed by the operations in which these variables are
+involved.
+
+More precisely, it is usually possible to deduce information about the
+result variable of an operation given information about its arguments.
+For example, we can say that the addition of two integers must be an
+integer.  Most programming languages have this property.  However,
+Python -- like many languages not specifically designed with type
+inference in mind -- does not possess a type system that allows much
+useful information to be derived about variables based on how they are
+\textit{used}; only on how they were \textit{produced}.  For example, a number of very
+different built-in types can be involved in an addition; the meaning of
+the addition and the type of the result depends on the type of the input
+arguments.  Merely knowing that a variable will be used in an addition
+does not give much information per se.  For this reason, our annotator
+works by flowing types forward, operation after operation, i.e. by
+performing abstract interpretation of the flow graphs.  In a sense, it
+is a more naive approach than the one taken by type systems specifically
+designed to enable more advanced inference algorithms.  For example,
+Hindley-Milner type inference works in an inside-out direction, by
+starting from individual operations and propagating type constraints
+outwards [H-M].
+
+Naturally, simply propagating types forward requires the use of a fixed
+point algorithm in the presence of loops in the flow graphs or in the
+inter-procedural call graph.  Indeed, we flow types forward from the
+beginning of the entry point function into each basic block, operation
+after operation, and follow all calls recursively.  During this process,
+each variable along the way gets a type.  In various cases, e.g. when we
+close a loop, the previously assigned types can be found to be too
+restrictive.  In this case, we generalise them to allow for a larger set
+of possible run-time values, and schedule the block where they appear
+for reflowing.  The more general type can generalise the types of the
+results of the variables in the block, which in turn can generalise the
+types that flow into the following blocks, and so on.  This process
+continues until a fixed point is reached.
+
+We can consider that all variables are initially assigned the "bottom"
+type corresponding to the empty set of possible run-time values.  Types
+can only ever be generalised, and the model is simple enough to show
+that there is no infinite chain of generalisation, so that this process
+necessarily terminates.
+
+
+\subsection{RPython types}
+
+As seen in section \ref{systemprog}, we use the annotator with more than one type
+systems.  The more interesting and complex one is the RPython type
+system, which describes how the input RPython program can be annotated.
+The other type systems contain lower-level, C-like types that are mostly
+unordered, thus forming more trivial lattices than the one formed by
+RPython types.
+
+The set $A$ of RPython types is defined as the following formal terms:
+
+\begin{itemize}
+\item $Bot$, $Top$ -- the minimum and maximum elements (corresponding
+      to "impossible value" and "most general value");
+
+\item $Int$, $NonNegInt$, $Bool$ -- integers, known-non-negative
+      integers, booleans;
+
+\item $Str$, $Char$ -- strings, characters (which are strings of
+      length 1);
+
+\item $Inst(class)$ -- instance of $class$ or a subclass thereof
+      (there is one such term per $class$);
+
+\item $List(v)$ -- list; $v$ is a variable summarising the items of
+      the list (there is one such term per variable);
+
+\item $Pbc(set)$ -- where the $set$ is a subset of the (finite) set of
+      all prebuilt constant objects.  This set includes all the
+      callables of the input program: functions, classes, and methods.
+
+\item $None$ -- stands for the singleton \texttt{None} object of
+      Python.
+
+\item $NullableStr$, $NullableInst(class)$ -- a string or
+      \texttt{None}; resp. an instance or \texttt{None}.
+\end{itemize}
+      
+Figures 6 and 7 shows how these types are ordered to form a lattice.  We
+mostly use its structure of [join-semilattice] only.
+
+\begin{verbatim}
+.. graphviz:: image/lattice1.dot
+
+:Figure 6: the lattice of annotations.
+\end{verbatim}
+
+\begin{verbatim}
+.. graphviz:: image/lattice2.dot
+
+:Figure 7: The part about instances and nullable instances, assuming a
+           simple class hierarchy with only two direct subclasses of
+           \texttt{object}.
+\end{verbatim}
+
+
+All list terms for all variables are unordered.  The Pbcs form a
+classical finite set-of-subsets lattice.  In addition, we have left
+out a number of other annotations that are irrelevant for the basic
+description of the annotator and straightforward to handle:
+$Dictionary$, $Tuple$, $Float$, $UnicodePoint$, $Iterator$, etc.  The
+complete list is described in [T].
+
+The type system moreover comes with a family of rules, which for every
+operation and every sensible combination of input types describes the
+type of its result variable.  Let $V$ be the set of Variables that
+appear in the user program's flow graphs.  Let $b$ be a map from $V$
+to $A$; it is a "binding" that gives to each variable a type.  The
+purpose of the annotator is to compute such a binding stepwise.
+
+Let $x$, $y$ and $z$ be Variables.  We introduce the rule:
+
+% XXX format this!
+$$
+\begin{array}{c}
+ z = \mathrm{add}(x, y), \; b(x) =
+    Int, \; Bool \leq b(y) \leq Int \\ \hline
+ b' = b \hbox{\ with\ } (z
+    \rightarrow Int) 
+\end{array}
+$$
+
+which specify that if we see the addition operation applied to
+Variables whose current binding is $Int$, a new binding $b'$ can be
+produced: it is $b$ except on $z$, where we have $b'(z) = Int$.
+
+The type inference engine can be seen as applying this kind of rules
+repeatedly.  It does not apply them in random order, but follows a
+forward-propagation order typical of abstract interpretation.
+
+It is outside the scope of the present paper to describe the type
+inference engine and the rules more formally.  The difficult points
+involve mutable containers -- e.g. initially empty list that are filled
+somewhere else -- and the discovery of instance attributes -- in Python,
+classes do not declare upfront a fixed set of attributes for their
+instances, let alone their types.  Both these examples require
+sophisticated reflowing techniques that invalidate existing types in
+already-annotated basic blocks, to account for the influence of more
+general types coming indirectly from a possibly distant part of the
+program.  The reader is referred to [D] for more information.
+
+
+\subsection{Termination and complexity}
+
+The lattice model clearly contains no infinite chain.  Moreover, it is
+designed to convince oneself that the number of reflowings required in
+practice is small.  For example, we are not trying to do range analysis
+beyond detecting non-negatives -- the reason is that range analysis is
+not an essential part of writing \textit{reasonably} efficient code.  Consider
+that a translated RPython program runs hundreds of times faster than
+when the same program is executed by the standard Python interpreter: in
+this context, range analysis appears less critical.  It is a possible
+optimization that we can introduce in a later, optional analysis and
+transformation step.
+
+The worst case behaviors that can appear in the model described above
+involve the lattice of Pbcs, involving variables that could contain
+e.g.  one function object among many.  An example of such behavior is
+code manipulating a table of function objects: when an item is read
+out of the table, its type is a large Pbc set: $Pbc(\{f1, f2, f3,
+\ldots\})$.  But in this example, the whole set is available at once,
+and not built incrementally by successive discoveries.  This seems to
+be often the case in practice: it is not very common for programs to
+manipulate objects that belong to a large but finite family -- and when
+they do, the whole family tends to be available early on, requiring
+few reflowing.
+
+This means that \textit{in practice} the complete process requires a time that
+is far lower than the worst case.  We have experimentally confirmed
+this: annotating the whole PyPy interpreter (90,000 lines) takes on the
+order of 5 to 10 minutes, and basic blocks are typically only reflown a
+handful of times, providing a close-to-linear practical complexity.
+
+We give formal termination and correctness proofs in [D], as well as
+worst-case bounds and some experimental evidence of their practical
+irrelevance.
+
+
+\subsection{Precision}
+
+Of course, this would be pointless if the annotation did not give
+precise enough information for our needs.  We must describe a detail of
+the abstract interpretation engine that is critical for precision: the
+propagation of conditional types.  Consider the following source code
+fragment::
+
+    if isinstance(x, MyClass):
+        f(x)
+    else:
+        g(x)
+
+Although the type of \texttt{x} may be some parent class of
+\texttt{MyClass}, it can be deduced to be of the more precise type
+$Inst(MyClass)$ within the positive branch of the \texttt{if}.
+(Remember that our graphs are in SSI form, which means that the
+\texttt{x} inside each basic block is a different Variable with a
+possibly different type as annotation.) XXX flow sensivity and SSA
+
+This is implemented by introducing an extended family of types for
+boolean values:
+
+$$
+Bool(v_1: (t_1, f_1), v_2: (t_2, f_2), ...)
+$$
+
+where the $v_n$ are variables and $t_n$ and $f_n$ are types.  The
+result of a check, like \texttt{isintance()} above, is typically
+annotated with such an extended $Bool$.  The meaning of the type is as
+follows: if the run-time value of the boolean is True, then we know
+that each variable $v_n$ has a type at most as general as $t_n$; and
+if the boolean is False, then each variable $v_n$ has a type at most
+as general as $f_n$.  This information is propagated from the check
+operation to the exit of the block via such an extended $Bool$ type,
+and the conditional exit logic in the type inference engine uses it to
+trim the types it propagates into the next blocks (this is where the
+\textit{meet} of the lattice is used).
+
+With the help of the above technique, we achieve a reasonable precision
+in small examples.  For larger examples, a different, non-local
+technique is required: the specialization of functions. XXX use 'polymorphism'
+
+As described in the introduction, the most important downside of our
+approach is that automatic specialization is a potential
+performance-killer.  We \textit{do} support specialization, however: we can
+generate several independently-annotated copies of the flow graphs of
+certain functions.  When annotating RPython programs, such
+specialization does not happen automatically: we rely on hints provided
+by the programmer in the source code, in the form of flags attached to
+function objects.  As we had this trade-off in mind when we wrote the
+Python interpreter of PyPy, we only had to add a dozen or so hints in
+the end.
+
+This does not mean that automatic specialization policies are difficult
+to implement.  Indeed, the simpler lower-level type systems rely quite
+heavily on them: this is because the system code helpers are often
+generic and can receive arguments of various C-level types.  In this
+case, because the types at this level are limited and mostly unordered,
+specializing all functions on their input argument's types works well.
+
+At the level of RPython, on the other hand, the range of specializations
+that make sense is much wider.  We have used anything between
+specialization by the type of an argument, to specialization by an
+expected-to-be-constant argument value, to memoized functions that the
+type inference engine will actually call during annotation and replace
+by look-up tables, to complete overriding of the annotator's behavior in
+extreme cases.  In this sense, the need for manual specialization turned
+into an advantage, in term of simplicity and flexibility of implementing
+and using new specialization schemes.
+
+This conclusion can be generalized.  We experimented with a simple
+approach to type inference that works well in practice, and that can
+very flexibly accomodate changes in the type system and even completely
+different type systems.  We think that the reasons for this success are
+to be found on the one hand in the (reasonable) restrictions we put on
+ourselves when designing the RPython language and writing the Python
+interpreter of PyPy in RPython, and on the other hand in an ad-hoc type
+system that is designed to produce enough precision (but not more) for
+the purpose of the subsequent transformations to C-level code.
+
+We should mention that restricting oneself to write RPython code instead
+of Python is still a burden, and that we are not proposing in any way
+that the Python language itself should evolve in this direction, nor
+even that RPython usage should become widespread.  It is a tool designed
+with a specific goal in mind, which is the ability to produce reasonably
+efficient, stand-alone code in a large variety of environment.
+
+
+
+\section{Experimental results}
+\label{experimentalresults}
+
+
+\subsection{Performance}
+
+Our tool-chain is capable of translating the Python interpreter of
+PyPy, written in RPython, producing right now either ANSI C code as
+described before, or LLVM\footnote{the LLVM project is the realisation
+of a portable assembler infrastructure, offering both a virtual
+machine with JIT capabilities and static compilation. Currently we are
+using the latter with its good high-level optimisations for PyPy.}
+assembler which is then natively compiled with LLVM tools.
+
+The tool-chain has been tested with and can sucessfully apply
+transformations enabling various combinations of features. The
+translated interpreters are benchmarked using pystone (a [Dhrystone]
+derivative traditionally used by the Python community, although it is a
+rather poor benchmark) and the classical [Richards] benchmark and
+compared against [CPython] 2.4.3 results:

+
+The numbers in parenthesis are slow-down factors compared to CPython.
+These measures reflect PyPy revision 27815, compiled with GCC 3.4.4.
+LLVM is version 1.8cvs (May 11, 2006).  The machine runs GNU/Linux SMP
+on an Intel(R) Pentium(R) 4 CPU at 3.20GHz with 2GB of RAM and 1MB of
+cache.  The rows correspond to variants of the translation process, as
+follows:
+
+pypy-c
+    The simplest variant: translated to C code with no explicit memory
+    management, and linked with the Boehm conservative GC [Boehm].
+
+pypy-c-thread
+    The same, with OS thread support enabled.  (For measurement purposes,
+    thread support is kept separate because it has an impact on the GC
+    performance.)
+
+pypy-c-stackless
+    The same as pypy-c, plus the "stackless transformation" step which
+    modifies the flow graph of all functions in a way that allows them
+    to save and restore their local state, as a way to enable coroutines.
+
+pypy-c-gcframework
+    In this variant, the "gc transformation" step inserts explicit
+    memory management and a simple mark-and-sweep GC implementation.
+    The resulting program is not linked with Boehm.  Note that it is not
+    possible to find all roots from the C stack in portable C; instead,
+    in this variant each function explicitly pushes and pops all roots
+    to an alternate stack around each subcall.
+
+pypy-c-stackless-gcframework
+    This variant combines the "gc transformation" step with the
+    "stackless transformation" step.  The overhead introduced by the
+    stackless feature is balanced with the removal of the overhead of
+    pushing and popping roots explicitly on an alternate stack: indeed,
+    in this variant it is possible to ask the functions in the current C
+    call chain to save their local state and return.  This has the
+    side-effect of moving all roots to the heap, where the GC can find
+    them.
+
+pypy-llvm-c
+    The same as pypy-c, but using the LLVM back-end instead of the C
+    back-end.  The LLVM assembler-compiler gives the best results when -
+    as we do here -- it optimizes its input and generates again C code,
+    which is fed to GCC.
+
+pypy-llvm-c-prof
+    The same as pypy-llvm-c, but using GCC's profile-driven
+    optimizations.
+
+The speed difference with CPython 2.4.3 can be explained at two levels.
+One is that CPython is hand-crafted C code that has been continuously
+optimized for a decade now, whereas the Python interpreter of PyPy first
+seeks flexibility and high abstraction levels.  The other, probably
+dominant, factor is that various indices show that our approach places a
+very high load on the GC and on the memory caches of the machine.  The
+Boehm GC is known to be less efficient than more customized approach;
+kernel-level profiling shows that pypy-c typically spends 30% of its
+time in the Boehm library.  Our current, naively simple mark-and-sweep
+GC is even quite worse.  The interaction with processor caches is also
+hard to predict and account for; in general, we tend to produce
+relatively large amounts of code and prebuilt data.
+
+
+\subsection{Translation times}
+
+A complete translation of the pypy-c variant takes about 39 minutes,
+divided as follows:
+
+\begin{verbatim}

++-------------------------------------------+------------------------------+
+\end{verbatim}
+
+An interesting feature of this table is that type inference is not the
+bottleneck.  Indeed, further transformation steps typically take longer
+than type inference alone.  This is the case for the LLTyper step,
+although it has a linear complexity on the size of its input (most
+transformations do).
+
+Other transformations like the "gc" and the "stackless" ones actually
+take more time, particuarly when used in combination with each other (we
+speculate it is because of the increase in size caused by the previous
+transformations).  A translation of pypy-c-stackless, without counting
+GCC time, takes 60 minutes; the same for pypy-c-stackless-gcframework
+takes XXX minutes.
+
+
+
+\section{Future work}
+\label{futurework}
+
+
+As described in section \ref{experimentalresults}, the performance of
+the compiled Python interpreters is still not up to competing with the
+well-established CPython.  We are always working to improve matters,
+considering new optimizations and better GCs.  Also, the OOTyper and
+back-ends for Smalltalk/Squeak and CLI/.NET are currently in progress.
+
+
+\subsection{JIT Specializer}
+
+So far, the PyPy tool-chain can only translate the Python interpreter of
+PyPy into a program which is again an interpreter -- the same interpreter
+translated to C, essentially, although we have already shown that some
+aspects can be "weaved" in at translation time, like support for
+coroutines.
+
+To achieve high performance for dynamic languages such as Python, the
+proven approach is to use dynamic compilation techniques, i.e. to write
+JITs.  With direct techniques, this is however a major endeavour, and
+increases the efforts to further evolve the language.
+
+In the context of the PyPy project, we are now exploring -- as we planned
+from the start -- the possibility to produce a JIT as a graph
+transformation aspect from the Python interpreter.  This idea is based
+on the theoretical possibiliy to turn interpreters into compilers by
+partial evaluation [PE].  In our approach, this is done by analysing
+the forest of flow graphs built from the Python interpreter, which is a
+well-suited input for this kind of techniques.  We can currently perform
+binding-time analysis [BTA] on these graphs, again with abstract
+interpretation techniques reusing the type inference engine.  The next
+step is to transform the graphs -- following the binding-time annotations
+- into a compiler; more precisely, in partial evalution terminology, a
+generating extension.  We can currently do this on trivial examples.
+
+The resulting generating extension will be essentially similar to
+[Psyco], which is the only (and hand-written) JIT available for Python so
+far, based on run-time specialization.
+
+
+
+\section{Related work}
+\label{relatedwork}
+
+Applying the expressiveness or at least syntax of very high-level and
+dynamically typed languages to their implementation has been
+investigated many times. 
+
+One typical approach is writing a static compiler.  The viability of
+and effort required for such an approach depend usually on the binding
+and dispatch semantics of the language.  Common Lisp native compilers,
+usable interactively and taking functions or files as compilation
+units are a well-known example of that approach.  Late binding for all
+names and load semantics make such an approach very hard for Python,
+if speed improvements are desired.
+
+It is more relevant to consider and compare with projects using
+dynamic and very-high level languages for interpreters and VM
+implementations, and Just-In-Time compilers.
+
+[Scheme48] was a Scheme implementation using a restricted Scheme, with
+static type inference based on Hindley-Milner, this is viable for
+Scheme as base language. Portability and simplicity were its major
+goals.
+
+[Squeak] is a Smalltalk implementation in Smalltalk. It uses SLang, a
+very restricted subset of Smalltalk with few types and strict
+conventions such that mostly direct translation to C is possible.
+Both the VM and the object memory and garbage collector support are
+explicitly written together in this style. Again simplicity and
+portability were the major goals, not sophisticated manipulation and
+analysis and waving in of features.
+
+[Jikes RVM] is a Java VM and Just-In-Time compiler written in Java.
+Bootstrapping happens by self-applying the compiler on a host VM, and
+dumping a snapshot from memory of the resulting native code.
+
+This approach enables directly high performance, at the price of
+portability as usual with pure native code emitting
+approaches. Modularity of features, when possible, is achieved with
+normal software modularity. The indirection costs are taken care by
+the inlining done by the compiler, sometimes even through explicit
+ways to request for it. In particular this modular approach is used
+for implementing a range of choices for GC support XXX ref.  This was
+the inspiration for PyPy own GC framework, although much more tuning
+and work went into Jikes RVM. PyPy own GC framework also exploits
+inlining of helpers and barriers to recover performance.
+
+Jikes RVM native JIT compilers can likely not easily be retargeted to
+run on top and target another VM (for example a CLR runtime) instead
+of hardware processors. Also Jikes RVM pays the complexity of writing
+a JIT up-front, which also means that features and semantics of the
+language are encoded in the JIT compiler code, meaning likely that
+major changes would correspond to major surgery needed on it.
+
+PyPy more indirect approach, together hopefully with our future work
+on generating a JIT compiler, tries to overcome these limitations, at
+the price of some more effort required to achieve very good
+performance. It is too soon to compare completely the complexity (and
+performance) trade-offs of these approaches.

 \section{Conclusion}
 \label{conclusion}
 
 
-XXX
-
-nice interpreter not polluted by implementation details
-here Python, but any interpreter works
-
-architecture allows implementing features at the right level
-
-dynamic language enables defining our own various type systems
-[ref pluggable type systems]
-
-practical VMs will result with a bit more efforts
+The PyPy project aims at showing that dynamic languages are suitable and
+quite useful for writing virtual machines in.  We believe that we have
+achieved this objective.  The present paper gave an overview of the
+architecture that enabled this result.  Experiments suggest that
+practical virtual machines could reasonably follow in the near future,
+with faster-than-current virtual machines with JIT specialization
+techniques for the mid-term future.
+
+Targetting platforms that are very different from C/Posix is work in
+progress, but given that many of the initial components are shared with
+the existing stack of transformations leading to C, we are confident
+that this work will soon give results.  Moreover, we believe that these
+results will show a reasonable efficiency, because the back-ends for VMs
+like Squeak and .NET can take advantage of high-level input (as opposed
+to trying to translate, say, C-like code to Smalltalk).
+
+A desirable property of our approach is to allow a given language and VM
+to be specified only once, in the form of an interpreter.  Moreover, the
+interpreter can be kept simple (and thus keep its role as a
+specification): not only is it written in a high-level language, but it
+is not overloaded with low-level design choices and implementation
+details.  This makes language evolution and experimentation easier.
+More generally, this property is important because many interpreters for
+very difference languages can be written: the simpler these interpreters
+can be kept, the more we win from our investment in writing the
+tool-chain itself - a one-time effort.
+
+Dynamic languages enable the definition of multiple custom type systems,
+similar to \textit{pluggable type systems} in [Bracha] but with simple
+type inference instead of explicit annotations.  This proved a key
+feature in implementing our translation tool-chain, because it makes a
+many-levels approach convenient: each abstraction level can provide an
+implementation for some of the features that the higher levels
+considered primitive.  It offsets the need to define a minimal kernel of
+primitives and build everything on top of it; instead, we have been able
+to implement, so to speak, the right feature at the right level.

+Abstract for Agile track at Europython 2006
+--------------------------------------------
+
+Kill -9: process refactoring in the PyPy project
+=============================
+
+In this talk we will present the experiences of running a collaborative
+OSS project within a EU-funded consortium structure. We will briefly present 
+the initial decision process for integrating the community and the commercial 
+aspects of the PyPy project. We will show how agile practices within the 
+development team, primarily sprint-driven methodology resulted in a need for 
+process refactoring and how a new agile management approach was 
+implemented. We will spice up the analysis of the main drivers behind this 
+change by refererring to Hershey-Blanchards Situational Leadership model.
