This is done in order to allow our analysis toolchain to apply +to PyPy itself. Indeed, the primary goal is to allow us to implement +the full Python language only once, as an interpreter, and derive +interesting tools from it; doing so requires this interpreter to be +analysable, hence the existence RPython. The RPython language and our +whole toolchain, despite their potential attraction, are so far meant as +an internal detail of the PyPy project. The programs that we are +deriving or plan to derive from PyPy include versions that run on very +diverse platforms (from C to Java/.NET to Smalltalk), and also versions +with modified execution models (from microthreads/coroutines to +just-in-time compilers). This is why we have split the process in +numerous interrelated phases, each at its own abstraction level. By +enabling changes to the appropriate level, this opens the door to a wide +range of retargetings of various kinds. + +Focusing on the analysis toolchain again, here is how the existence of +each component is justified (see below for *how* each component reaches +the claimed goals): + +* the `Flow Object Space`_ is a short but generic plug-in component for + the Python interpreter of PyPy (an abstract domain, more precisely). + 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 standard Python interpreter. In effect, the + Flow Object Space enables an interpreter for *any* language to work as + a front-end for the rest of the toolchain. + +* the `Annotator`_ is performing type inference. This part is best + implemented separately from other parts because it is based on a + fixpoint research algorithm. It is mostly this part that defines and + restricts what RPython exactly is. After annotation, the control flow + graphs still contain all the original relatively-high-level RPython + operations; the inferred information is only used in the next step. + +* the `RTyper`_ is the first component involved in `Code Generation`_. + By itself, it does not emit any source code: it only replaces all + RPython-level operations with lower-level operations in all control + flow graphs. Each replacement is based on the type information + collected by the annotator. In some sense the RTyper is the central + bridge between the analysed program, written in RPython, and the + target language and platform, which has different and usually + lower-level operations, requirements and libraries. This RTyper is + written in a modular way that allows it to be retargeted to various + environments: for example, to target C-like languages we produce + graphs that contain C-like operations, e.g. pointer manipulations; on + the other hand, to target OO languages we need to produce graphs with + operations like method calls. + +* at the end, a back-end is responsible for generating actual source + code from the flow graphs it receives. Given that the flow graphs are + already at the correct level, the only remaining problems are at the + level of difficulties with or limitations of the target language. + This part depends strongly on the details of the target language, so + little code can be shared between the different back-ends (even + between back-ends inputting the same low-level flow graphs, e.g. the C + and the LLVM_ back-ends).

One cause for this is the need to manipulate Python objects like +functions directly. This makes it hard to attach additional information directly +to the objects. It makes specialization messy because it has to create new dummy +function objects just to represent the various specialized versions of the function. + + +Plan +==== + +Let's introduce nice wrapper objects. This refactoring is oriented towards +the following goal: replacing the content of SomePBC() with a plain set of +"description" wrapper objects. We shall probably also remove the possibility +for None to explicitly be in the set and add a can_be_None flag (this is +closer to what the other SomeXxx classes do). + + +XxxDesc classes +=============== + +To be declared in module pypy.annotator.desc, with a mapping +annotator.bookkeeper.descs = {: } +accessed with bookkeepeer.getdesc(). + +Maybe later the module should be moved out of pypy.annotation but for now I +suppose that it's the best place. + +The goal is to have a single Desc wrapper even for functions and classes that +are specialized. + +FunctionDesc + + Describes (usually) a Python function object. Contains flow graphs: one + in the common case, zero for external functions, more than one if there + are several specialized versions. Also describes the signature of the + function in a nice format (i.e. not by relying on func_code inspection). + +ClassDesc + + Describes a Python class object. Generally just maps to a ClassDef, but + could map to more than one in the presence of specialization. So we get + SomePBC({}) annotations for the class, and when it's + instantiated it becomes SomeInstance(classdef=...) for the particular + selected classdef. + +MethodDesc + + Describes a bound method. Just references a FunctionDesc and a ClassDef + (not a ClassDesc, because it's read out of a SomeInstance). + +FrozenDesc + + Describes a frozen pre-built instance. That's also a good place to store + some information currently in dictionaries of the bookkeeper. + +MethodOfFrozenDesc + + Describes a method of a FrozenDesc. Just references a FunctionDesc and a + FrozenDesc. + +NB: unbound method objects are the same as function for our purposes, so they +become the same FunctionDesc as their im_func. + +These XxxDesc classes should share some common interface, as we'll see during +the refactoring.

This document describes the current state of the implementation of +memory object model, automatic memory management and threading models as well +as possible future developments. + +XXX + +Background +=========== + +The main emphasis of the PyPy project is that of integration: we want to make +changing memory management and threading techniques possible while at the same +time influencing the interpreter as little as possible. It is not the current +goal to optimize the current approaches in extreme ways rather to produce solid +implementations and to provide an environment where experiments with +fundamentally different ways to implement these things is possible and +reasonably easy. + +XXX + +The low level object model +=========================== + + - low level object model, data structures current layouts (also a word on the + example of cached functions with PBC argument?) + - how we deal with id hashes + - probably describe in more detail the possibilies to completely change the + representation of objects, etc. + +XXX how detailed does this need to be described here? + +Automatic Memory Management Implementations +============================================ + +The whole implementation of the PyPy interpreter assumes automatic memory +management, e.g. automatic reclamation of memory that is no longer used. The +whole analysis toolchain also assumes that memory management is being taken +care of. Only the backends have to concern themselves with that issue. For +backends that target environments that have their own garbage collector, like +Smalltalk or Javascript, this is not an issue. For other targets like C and +LLVM the backend has to produce code that uses some sort of garbage collection. + +This approach has several advantages. It makes it possible to target different +platforms, with and without integrated garbage collection. Furthermore the +interpreter implementation is not complicated by the need to do explicit memory +management everywhere. Even more important the backend can optimize the memory +handling to fit a certain situation (like a machine with very restricted +memory) or completely replace the memory management technique or memory model +with a different one without having to change interpreter code. Additionally +the backend can use information + +Using the Boehm garbage collector +----------------------------------- + +At the moment there are two different garbage collectors implemented in the C +backend (which is the most complete backend right now). One of them uses the +existing Boehm-Demers-Weiser garbage collector [BOEHM]_. For every memory +allocating operation in a low level flow graph the C backend introduzes a call +to a function of the boehm collector which returns a suitable amount of memory. +Since the C backends has a lot of information avaiable about the data structure +being allocated it can choose the memory allocation function out of the Boehm +API that fits best. For example for objects that do not contain references to +other objects (e.g. strings) there is a special allocating function that +signals to the collector that it does not need to consider this memory when +tracing pointers. + +XXX + +XXX maybe describe disadvantages of boehm, like conservativity, we could do +better...? + +Using a simple reference counting garbage collector +----------------------------------------------------- + +The other implemented garbage collector is a simple reference counting scheme. +The C backend inserts a reference count field into every structure that is +handled by the garbage collector and puts increment and decrement operations +for this reference count into suitable places in the resulting C code. After +every reference decrement operations a check is performed whether the reference +count has dropped to zero. If this is the case the memory of the object will be +reclaimed after the references counts of the objects the original object +references are decremented as well. + +XXX: do we mention that our incref/decref placement is dumb? or do we assume +that it will be improved until the review? + +The current reference counting implementation has a drawback: it cannot deal +with circular references, which is a fundamental flaw of reference counting +memory management schemes. CPython solves this problem by having special code +that handles circular garbage which PyPy lacks at the moment. This problem has +to be addressed in the future to make the reference counting scheme a viable +garbage collector. (XXX should we rather not mention this?) + +Finalization and weak references +--------------------------------- + +XXX + + +Simple escape analysis to remove memory allocation +--------------------------------------------------- + +We implemented also a technique to prevent some amount of memory allocation. +Sometimes it is possible to deduce from the flow graphs that an object lives +exactly as long as the stack frame of the function where it is allocated in. +This happens if no pointer to the object is stored into another object and if +no pointer to the object is returned from the function. If this is the case and +if the size of the object is known in advance the object can be allocated on +the stack. To achieve this, the object is "exploded", that means that for every +element of the structure a new variable is generated that is handed around in +the graph. Reads from elements of the structure are removed and just replaced +by one of the variables, writes by assignements to same. + +XXX + +Threading Model Implementations +============================================ + +XXX nice introductory paragraph + +No threading +------------- + +XXX + +Threading with a Global Interpreter Lock +------------------------------------------ + +XXX describe what's there + +todo: +GIL release around system calls +maybe a locking threading model around space operations + +Stackless C code +----------------- + +XXX + + +Open Challenges +================ + +XXX + +open challenges for phase 2: + + - more clever incref/decref policy + - more sophisticated structure inlining ? possibly + - full GC hooks?
