+NumPy status update #5
+----------------------
+
+Hello.
+
+I'm quite excited to inform that work on NumPy in PyPy has been restarted
+and there has been quite a bit of progress on the NumPy front in PyPy in the
+past two months. Things that happened:
+
+* **complex dtype support** - thanks to matti picus, NumPy on PyPy now supports
+  complex dtype (only complex128 so far, there is work on the other part)
+
+* **big refactoring** - probably the biggest issue we did was finishing
+  a big refactoring that disabled some speedups (notably lazy computation
+  of arrays), but lowered the barrier of implementing cool new features.
+
+* **fancy indexing support** - all fancy indexing tricks should now work,
+  including ``a[b]`` where ``b`` is an array of integers.
+
+* **newaxis support** - now you can use newaxis features
+
+* **improvements to ``intp``, ``uintp``, ``void``, ``string`` and record dtypes**
+
+Features that have active branches, but hasn't been merged:
+
+* **float16 dtype support**
+
+* **missing ndarray attributes** - this is a branch to finish all attributes
+  on ndarray, hence ending one chapter.
+
+* **pickling support for numarray** - hasn't started yet, but next on the list
+
+More importantly, we're getting very close to able to import the python part
+of the original numpy with only import modifications and running it's tests.
+Most tests will fail at this point, however it'll be a good start for another
+chapter :-)
+
+Cheers,
+fijal

-imap(fun, p, q, ...) --> fun(p0, q0), fun(p1, q1), ...
-starmap(fun, seq) --> fun(*seq[0]), fun(*seq[1]), ...
-tee(it, n=2) --> (it1, it2 , ... itn) splits one iterator into n
-chain(p, q, ...) --> p0, p1, ... plast, q0, q1, ... 
-takewhile(pred, seq) --> seq[0], seq[1], until pred fails
-dropwhile(pred, seq) --> seq[n], seq[n+1], starting when pred fails

-* Hash randomization is not supported in PyPy.  Passing ``-R`` to the
-  command line, or setting the ``PYTHONHASHSEED`` environment variable
-  will display a warning message.
+* Hash randomization (``-R``) is ignored in PyPy.  As documented in
+  http://bugs.python.org/issue14621 , some of us believe it has no
+  purpose in CPython either.
 
-* ``sys.setrecursionlimit()`` is ignored (and not needed) on
-  PyPy.  On CPython it would set the maximum number of nested
-  calls that can occur before a RuntimeError is raised; on PyPy
-  overflowing the stack also causes RuntimeErrors, but the limit
-  is checked at a lower level.  (The limit is currently hard-coded
-  at 768 KB, corresponding to roughly 1480 Python calls on
-  Linux.)
+* ``sys.setrecursionlimit(n)`` sets the limit only approximately,
+  by setting the usable stack space to ``n * 768`` bytes.  On Linux,
+  depending on the compiler settings, the default of 768KB is enough
+  for about 1400 calls.
 
 * assignment to ``__class__`` is limited to the cases where it
   works on CPython 2.5.  On CPython 2.6 and 2.7 it works in a bit

Subject: [pypy-commit] pypy continulet-jit-3: JIT_FRAME -> FORCE_TOKEN
 again. The idea is that a "jit frame"
Message-ID: <20121105022829.21A861C014B@cobra.cs.uni-duesseldorf.de>

Changeset: r58729:9601aaf798dd
Date: 2012-11-05 02:47 +0100
http://bitbucket.org/pypy/pypy/changeset/9601aaf798dd/

Log:	JIT_FRAME -> FORCE_TOKEN again. The idea is that a "jit frame"
	corresponds to a dead finished state, whereas a "force token" is a
	gcref that may be force()d to become a "jit frame".

-* Hash randomization is not supported in PyPy.  Passing ``-R`` to the

-  will display a warning message.
+* Hash randomization (``-R``) is ignored in PyPy.  As documented in
+  http://bugs.python.org/issue14621 , some of us believe it has no
+  purpose in CPython either.
 
-* ``sys.setrecursionlimit()`` is ignored (and not needed) on
-  PyPy.  On CPython it would set the maximum number of nested
-  calls that can occur before a RuntimeError is raised; on PyPy
-  overflowing the stack also causes RuntimeErrors, but the limit
-  is checked at a lower level.  (The limit is currently hard-coded
-  at 768 KB, corresponding to roughly 1480 Python calls on
-  Linux.)
+* ``sys.setrecursionlimit(n)`` sets the limit only approximately,
+  by setting the usable stack space to ``n * 768`` bytes.  On Linux,
+  depending on the compiler settings, the default of 768KB is enough
+  for about 1400 calls.
 
 * assignment to ``__class__`` is limited to the cases where it
   works on CPython 2.5.  On CPython 2.6 and 2.7 it works in a bit

Subject: [pypy-commit] pypy py3k: hg merge default;
 in particular, this also merges the unicode-strategies branch;
 the merge was not completely straightforward because some strategies were
 migrated from string to unicode in py3k. However, earlier it was a mess and
 now all containers have separated strategies for string/bytes and unicode

+\item ``Optimistic'' approach:
+%
+\begin{itemize}
+
+\item no lock to protect shared data in memory
+
+\item instead, track all memory accesses
+
+\item detect actual conflicts
+
+\item if conflict, restart the whole ``transaction''
+
+\end{itemize}

+\end{itemize}

+%
+\begin{itemize}

+\item Easier to use

+\item and others

+\end{itemize}

+\pause
+%
+\begin{itemize}
+
+\item STM = Software Transactional Memory
+%
+\begin{itemize}
+
+\item various approaches
+
+\item large overhead (2x-10x), but getting faster
+
+\item experimental in PyPy: read/write barriers, as with GC
+
+\end{itemize}
+
+\end{itemize}
+\end{frame}
+\begin{frame}
+\frametitle{The catch}
+
+
+\pause
+%
+\begin{itemize}
+
+\item You Still Have To Use Threads
+
+\end{itemize}
+
+\pause
+%
+\begin{itemize}
+
+\item Threads are hard to debug, non-reproductible
+
+\end{itemize}
+
+\pause
+%
+\begin{itemize}
+
+\item Threads are Messy
+
+\end{itemize}
+\end{frame}
+\begin{frame}
+\frametitle{Issue with threads}
+
+%
+\begin{itemize}
+
+\item TM does not solve this problem:
+
+\item How do you know if you missed a place to put \texttt{atomic} around?
+%
+\begin{itemize}
+
+\item hard to catch by writing tests
+
+\item instead you get obscure rare run-time crashes
+
+\end{itemize}
+
+\end{itemize}
+
+\pause
+%
+\begin{itemize}
+
+\item What if we put \texttt{atomic} everywhere?
+
+\end{itemize}
+\end{frame}
+\begin{frame}
+\frametitle{Analogy with Garbage Collection}
+
+%
+\begin{itemize}
+
+\item Explicit Memory Management:
+%
+\begin{itemize}
+
+\item messy, hard to debug rare leaks or corruptions
+
+\end{itemize}
+
+\end{itemize}
+
+\pause
+%
+\begin{itemize}
+
+\item Automatic GC solves it
+%
+\begin{itemize}
+
+\item common languages either have a GC or not
+
+\item if they have a GC, it controls almost \emph{all} objects
+
+\item not just a small part of them
+
+\end{itemize}
+
+\end{itemize}
+\end{frame}
+\begin{frame}
+\frametitle{Proposed solution}
+
+%
+\begin{itemize}
+
+\item Put \texttt{atomic} everywhere...
+
+\item in other words, Run Everything with TM
+
+\end{itemize}
+\end{frame}
+\begin{frame}
+\frametitle{Proposed solution}
+
+%
+\begin{itemize}
+
+\item Really needs TM.  With locks, you'd get this:
+
+\end{itemize}
+
+\noindent\makebox[\textwidth][c]{\includegraphics[scale=0.700000]{GIL.png}}
+%
+\begin{itemize}
+
+\item With TM you can get this:

+
+\noindent\makebox[\textwidth][c]{\includegraphics[scale=0.700000]{STM.png}}
+\end{frame}
+\begin{frame}
+\frametitle{In a few words}
+
+%
+\begin{itemize}
+
+\item Longer transactions
+
+\item Corresponding to larger parts of the program
+
+\item The underlying multi-threaded model becomes implicit
+
+\end{itemize}
+\end{frame}
+\begin{frame}
+\frametitle{Typical example}
+
+%
+\begin{itemize}
+
+\item You want to run \texttt{f1()} and \texttt{f2()} and \texttt{f3()}
+
+\end{itemize}
+
+\pause
+%
+\begin{itemize}
+
+\item Assume they are ``mostly independent''
+%
+\begin{itemize}
+
+\item i.e. we expect that we can run them in parallel
+
+\item but we cannot prove it, we just hope that in the common case we can
+
+\end{itemize}
+
+\end{itemize}
+
+\pause
+%
+\begin{itemize}
+
+\item In case of conflicts, we don't want random behavior
+%
+\begin{itemize}
+
+\item i.e. we don't want thread-like non-determinism and crashes
+
+\end{itemize}
+
+\end{itemize}
+\end{frame}
+\begin{frame}
+\frametitle{Pooling and atomic statements}
+
+%
+\begin{itemize}
+
+\item Solution: use a library that creates a pool of threads
+
+\item Each thread picks a function from the list and runs it
+with \texttt{atomic}
+
+\end{itemize}
+\end{frame}
+\begin{frame}
+\frametitle{Results}
+
+%
+\begin{itemize}
+
+\item The behavior is ``as if'' we had run \texttt{f1()}, \texttt{f2()}
+and \texttt{f3()} sequentially
+
+\item The programmer chooses if he wants this fixed order,
+or if any order is fine
+
+\item Threads are hidden from the programmer
+
+\end{itemize}
+\end{frame}
+\begin{frame}
+\frametitle{More generally}
+
+%
+\begin{itemize}
+
+\item This was an example only
+
+\item \textbf{TM gives various new ways to hide threads under a nice interface}
+
+\end{itemize}
+\end{frame}
+\begin{frame}
+\frametitle{Not the Ultimate Solution}
+
+%
+\begin{itemize}
+
+\item Much easier for the programmer to get reproducible results
+
+\item But maybe too many conflicts
+
+\end{itemize}
+
+\pause
+%
+\begin{itemize}
+
+\item ``The right side'' of the problem
+%
+\begin{itemize}
+
+\item start with a working program, and improve performance
+
+\item as opposed to: with locks, start with a fast program, and debug crashes
+
+\item we will need new debugging tools
+
+\end{itemize}

+Synchronization with TM
+-----------------------
+
+* "Optimistic" approach:
+
+  - no lock to protect shared data in memory
+
+  - instead, track all memory accesses
+
+  - detect actual conflicts
+
+  - if conflict, restart the whole "transaction"
+
+|pause|
+
+* Easier to use
+
+  - no need to name locks
+
+  - no deadlocks
+
+  - "composability"
+
+
+HTM versus STM
+--------------
+
+* HTM = Hardware Transactional Memory
+
+  - Intel Haswell CPU, 2013
+
+  - and others
+
+|pause|
+
+* STM = Software Transactional Memory
+
+  - various approaches
+
+  - large overhead (2x-10x), but getting faster
+
+  - experimental in PyPy: read/write barriers, as with GC
+
+
+The catch
+---------
+
+|pause|
+
+* You Still Have To Use Threads
+
+|pause|
+
+* Threads are hard to debug, non-reproductible
+
+|pause|
+
+* Threads are Messy
+
+
+Issue with threads
+------------------
+
+* TM does not solve this problem:
+
+* How do you know if you missed a place to put ``atomic`` around?
+
+  - hard to catch by writing tests
+
+  - instead you get obscure rare run-time crashes
+
+|pause|
+
+* What if we put ``atomic`` everywhere?
+
+
+Analogy with Garbage Collection
+-------------------------------
+
+* Explicit Memory Management:
+
+  - messy, hard to debug rare leaks or corruptions
+
+|pause|
+
+* Automatic GC solves it
+
+  - common languages either have a GC or not
+
+  - if they have a GC, it controls almost *all* objects
+
+  - not just a small part of them
+
+
+Proposed solution
+-----------------
+
+* Put ``atomic`` everywhere...
+
+* in other words, Run Everything with TM
+
+
+Proposed solution
+-----------------
+
+* Really needs TM.  With locks, you'd get this:
+
+.. image:: GIL.png
+   :scale: 70%
+   :align: center
+
+* With TM you can get this:
+
+.. image:: STM.png
+   :scale: 70%
+   :align: center
+
+
+In a few words
+--------------
+
+* Longer transactions
+
+* Corresponding to larger parts of the program
+
+* The underlying multi-threaded model becomes implicit
+
+
+Typical example
+---------------
+
+* You want to run ``f1()`` and ``f2()`` and ``f3()``
+
+|pause|
+
+* Assume they are "mostly independent"
+
+  - i.e. we expect that we can run them in parallel
+
+  - but we cannot prove it, we just hope that in the common case we can
+
+|pause|
+
+* In case of conflicts, we don't want random behavior
+
+  - i.e. we don't want thread-like non-determinism and crashes
+
+
+Pooling and atomic statements
+-----------------------------
+
+* Solution: use a library that creates a pool of threads
+
+* Each thread picks a function from the list and runs it
+  with ``atomic``
+
+
+Results
+-------
+
+* The behavior is "as if" we had run ``f1()``, ``f2()``
+  and ``f3()`` sequentially
+
+* The programmer chooses if he wants this fixed order,
+  or if any order is fine
+
+* Threads are hidden from the programmer
+
+
+More generally
+--------------
+
+* This was an example only
+
+* **TM gives various new ways to hide threads under a nice interface**
+
+
+Not the Ultimate Solution
+-------------------------
+
+* Much easier for the programmer to get reproducible results
+
+* But maybe too many conflicts
+
+|pause|
+
+* "The right side" of the problem
+
+  - start with a working program, and improve performance
+
+  - as opposed to: with locks, start with a fast program, and debug crashes
+
+  - we will need new debugging tools
+
+
+PyPy-STM
+--------
+
+* PyPy-STM: a version of PyPy with Software Transactional Memory
+
+  - in-progress, but basically working
+
+* http://pypy.org/
+
+|pause|
+
+* Thank you!

+===============
+PyPy 2.0 beta 1
+===============
+
+We're pleased to announce the 2.0 beta 1 release of PyPy. This release is
+not a typical beta, in a sense the stability is the same or better than 1.9
+and can be used in production. It does however include a few performance
+regressions documented below that don't quite make it 2.0 final.
+
+The main features of this release is ARM processor support and the first
+release of CFFI-capable PyPy. It also includes numerous improvements
+to the numpy in pypy effort, cpyext and performance.
+
+You can download the PyPy 2.0 beta 1 release here:
+
+    http://pypy.org/download.html 
+
+What is PyPy?
+=============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7. It's fast (`pypy 2.0 beta 1 and cpython 2.7.3`_
+performance comparison) due to its integrated tracing JIT compiler.
+
+This release supports x86 machines running Linux 32/64, Mac OS X 64 or
+Windows 32. It also supports ARM machines running Linux.
+Windows 64 work is still stalling, we would welcome a volunteer
+to handle that.
+
+.. XXX link
+
+XXX donors info?
+
+Regressions
+===========
+
+Reasons why this is not PyPy 2.0:
+
+* ``ctypes`` fast path is now slower than it used to be. ``ctypes`` in PyPy
+  1.9 was either incredibly fast or slower than CPython depending whether
+  you hit the fast path or not. Right now it's usually simply slower. We're
+  probably going to rewrite ``ctypes`` using ``cffi`` which will make it
+  universally faster.
+
+* ``cffi``, while very fast is missing one optimization that will make
+  it as fast as a native call from C.
+
+* ``numpypy`` lazy computation was disabled in the sake of simplicity. We should
+  reenable this for the final 2.0 release.
+
+Highlights
+==========
+
+* ``cffi`` is officially supported by PyPy. You can install it normally by
+  using ``pip install cffi`` once you have PyPy installed. Corresponding
+  ``0.4`` version of ``cffi`` has been released.
+
+* ARM is not an officially supported processor architecture.
+  XXX write down few words here
+
+* This release contains the latest Python standard library 2.7.3 and is fully
+  compatible with Python 2.7.3.
+
+* It does not however contain hash randomization, since the solution present
+  in CPython is not solving the problem anyway. The reason why can be
+  found on the `CPython issue tracker`_.
+
+* ``gc.get_referrers`` is not faster.
+
+* Various numpy improvements. List include:
+
+  * axis argument support in many places
+
+  * full support for fancy indexing
+
+  * ``complex128`` and ``complex64`` dtypes
+
+* `JIT hooks`_ are now powerful tool to introspect the JITting process that
+  PyPy performs.
+
+* ``**kwds`` usage is much faster in a typical scenario
+
+* ``long`` builtin type is now as fast as CPython's (from roughly 2x slower)
+
+* Unicodes stored in ``dict``/``set``/``list`` are now faster.

Subject: [pypy-commit] pypy py3k: Finally found why translation of the
 _hashlib module segfaults with pypy:
Message-ID: <20121113233057.2F3C51C1E95@cobra.cs.uni-duesseldorf.de>

Author: Amaury Forgeot d'Arc <amauryfa at gmail.com>
Branch: py3k
Changeset: r58869:17c0b573b0f8
Date: 2012-11-14 00:30 +0100
http://bitbucket.org/pypy/pypy/changeset/17c0b573b0f8/

Log:	Finally found why translation of the _hashlib module segfaults with
	pypy: openssl is statically linked, so init_digest() *of the shared
	library* has not been called by the host Python.

Subject: [pypy-commit] pypy default: Merge the autoreds branch. It adds two
 features to the JIT:
Message-ID: <20121114124855.2101B1C0012@cobra.cs.uni-duesseldorf.de>

Changeset: r58887:589bad09a3bb
Date: 2012-11-14 13:48 +0100
http://bitbucket.org/pypy/pypy/changeset/589bad09a3bb/

Log:	Merge the autoreds branch. It adds two features to the JIT:

	- the ability to pass reds='auto' to the JitDriver: in this case,
	the set of reds variables needed by jit_merge_point is
	automatically computed by warmspot.py. Having automatic reds is
	more limiting because so far only jit_merge_point is supported
	(i.e., no can_enter_jit), and it is not compatible with JitDriver
	hooks (e.g., get_printable_location, etc.)

	- the ability to declare to decorate a particular function with
	@jitdriver.inline_in_portal: this allows to write RPython iterators
	which are automatically turned into portals whenever you iterate
	with a for loop over them.

+===============
+PyPy 2.0 beta 1
+===============
+
+We're pleased to announce the 2.0 beta 1 release of PyPy. This release is
+not a typical beta, in a sense the stability is the same or better than 1.9
+and can be used in production. It does however include a few performance
+regressions documented below that don't allow us to label is as 2.0 final.
+(It also contains many performance improvements.)
+
+The main features of this release are support for ARM processor and
+compatibility with CFFI. It also includes
+numerous improvements to the numpy in pypy effort, cpyext and performance.
+
+You can download the PyPy 2.0 beta 1 release here:
+
+    http://pypy.org/download.html 
+
+What is PyPy?
+=============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7.3. It's fast (`pypy 2.0 beta 1 and cpython 2.7.3`_
+performance comparison) due to its integrated tracing JIT compiler.
+
+This release supports x86 machines running Linux 32/64, Mac OS X 64 or
+Windows 32. It also supports ARM machines running Linux.
+Windows 64 work is still stalling, we would welcome a volunteer
+to handle that.
+
+.. XXX link
+
+XXX donors info?
+
+Regressions
+===========
+
+Reasons why this is not PyPy 2.0:
+
+* the ``ctypes`` fast path is now slower than it used to be. In PyPy
+  1.9 ``ctypes`` was either incredibly faster or slower than CPython depending whether
+  you hit the fast path or not. Right now it's usually simply slower. We're
+  probably going to rewrite ``ctypes`` using ``cffi``, which will make it
+  universally faster.
+
+* ``cffi`` (an alternative to interfacing with C code) is very fast, but
+  it is missing one optimization that will make it as fast as a native
+  call from C.
+
+* ``numpypy`` lazy computation was disabled for the sake of simplicity.
+  We should reenable this for the final 2.0 release.
+
+Highlights
+==========
+
+* ``cffi`` is officially supported by PyPy. You can install it normally by
+  using ``pip install cffi`` once you have PyPy installed. The corresponding
+  ``0.4`` version of ``cffi`` has been released.
+
+* ARM is now an officially supported processor architecture.
+  PyPy now work on soft-float ARM/Linux builds.  Currently ARM processors
+  supporting the ARMv7 and later ISA that include a floating-point unit are
+  supported.
+
+* This release contains the latest Python standard library 2.7.3 and is fully
+  compatible with Python 2.7.3.
+
+* It does not however contain hash randomization, since the solution present
+  in CPython is not solving the problem anyway. The reason can be
+  found on the `CPython issue tracker`_.
+
+* ``gc.get_referrers()`` is now faster.
+
+* Various numpy improvements. The list includes:
+
+  * axis argument support in many places
+
+  * full support for fancy indexing
+
+  * ``complex128`` and ``complex64`` dtypes
+
+* `JIT hooks`_ are now a powerful tool to introspect the JITting process that
+  PyPy performs.
+
+* ``**kwds`` usage is much faster in the typical scenario
+
+* operations on ``long`` objects are now as fast as in CPython (from
+  roughly 2x slower)
+
+* We now have special strategies for ``dict``/``set``/``list`` which contain
+  unicode strings, which means that now such collections will be both faster
+  and more compact.

+===============
+PyPy 2.0 beta 1
+===============
+
+We're pleased to announce the 2.0 beta 1 release of PyPy. This release is
+not a typical beta, in a sense the stability is the same or better than 1.9
+and can be used in production. It does however include a few performance
+regressions documented below that don't allow us to label is as 2.0 final.
+(It also contains many performance improvements.)
+
+The main features of this release are support for ARM processor and
+compatibility with CFFI. It also includes
+numerous improvements to the numpy in pypy effort, cpyext and performance.
+
+You can download the PyPy 2.0 beta 1 release here:
+
+    http://pypy.org/download.html 
+
+What is PyPy?
+=============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7.3. It's fast (`pypy 2.0 beta 1 and cpython 2.7.3`_
+performance comparison) due to its integrated tracing JIT compiler.
+
+This release supports x86 machines running Linux 32/64, Mac OS X 64 or
+Windows 32. It also supports ARM machines running Linux.
+Windows 64 work is still stalling, we would welcome a volunteer
+to handle that.
+
+.. XXX link
+
+XXX donors info?
+
+Regressions
+===========
+
+Reasons why this is not PyPy 2.0:
+
+* the ``ctypes`` fast path is now slower than it used to be. In PyPy
+  1.9 ``ctypes`` was either incredibly faster or slower than CPython depending whether
+  you hit the fast path or not. Right now it's usually simply slower. We're
+  probably going to rewrite ``ctypes`` using ``cffi``, which will make it
+  universally faster.
+
+* ``cffi`` (an alternative to interfacing with C code) is very fast, but
+  it is missing one optimization that will make it as fast as a native
+  call from C.
+
+* ``numpypy`` lazy computation was disabled for the sake of simplicity.
+  We should reenable this for the final 2.0 release.
+
+Highlights
+==========
+
+* ``cffi`` is officially supported by PyPy. You can install it normally by
+  using ``pip install cffi`` once you have PyPy installed. The corresponding
+  ``0.4`` version of ``cffi`` has been released.
+
+* ARM is now an officially supported processor architecture.
+  PyPy now work on soft-float ARM/Linux builds.  Currently ARM processors
+  supporting the ARMv7 and later ISA that include a floating-point unit are
+  supported.
+
+* This release contains the latest Python standard library 2.7.3 and is fully
+  compatible with Python 2.7.3.
+
+* It does not however contain hash randomization, since the solution present
+  in CPython is not solving the problem anyway. The reason can be
+  found on the `CPython issue tracker`_.
+
+* ``gc.get_referrers()`` is now faster.
+
+* Various numpy improvements. The list includes:
+
+  * axis argument support in many places
+
+  * full support for fancy indexing
+
+  * ``complex128`` and ``complex64`` dtypes
+
+* `JIT hooks`_ are now a powerful tool to introspect the JITting process that
+  PyPy performs.
+
+* ``**kwds`` usage is much faster in the typical scenario
+
+* operations on ``long`` objects are now as fast as in CPython (from
+  roughly 2x slower)
+
+* We now have special strategies for ``dict``/``set``/``list`` which contain
+  unicode strings, which means that now such collections will be both faster
+  and more compact.

+PyPy 2.0 beta 1
+===============
+
+We're pleased to announce the 2.0 beta 1 release of PyPy. This release is
+not a typical beta, in a sense the stability is the same or better than 1.9
+and can be used in production. It does however include a few performance
+regressions documented below that don't allow us to label is as 2.0 final.
+(It also contains many performance improvements.)
+
+The main features of this release are support for ARM processor and
+compatibility with CFFI. It also includes
+numerous improvements to the numpy in pypy effort, cpyext and performance.
+
+You can download the PyPy 2.0 beta 1 release here:
+
+    http://pypy.org/download.html 
+
+What is PyPy?
+=============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7.3. It's fast (`pypy 2.0 beta 1 and cpython 2.7.3`_
+performance comparison) due to its integrated tracing JIT compiler.
+
+This release supports x86 machines running Linux 32/64, Mac OS X 64 or
+Windows 32. It also supports ARM machines running Linux.
+Windows 64 work is still stalling, we would welcome a volunteer
+to handle that.
+
+.. XXX link
+
+XXX donors info?
+
+Regressions
+===========
+
+Reasons why this is not PyPy 2.0:
+
+* the ``ctypes`` fast path is now slower than it used to be. In PyPy
+  1.9 ``ctypes`` was either incredibly faster or slower than CPython depending whether
+  you hit the fast path or not. Right now it's usually simply slower. We're
+  probably going to rewrite ``ctypes`` using ``cffi``, which will make it
+  universally faster.
+
+* ``cffi`` (an alternative to interfacing with C code) is very fast, but
+  it is missing one optimization that will make it as fast as a native
+  call from C.
+
+* ``numpypy`` lazy computation was disabled for the sake of simplicity.
+  We should reenable this for the final 2.0 release.
+
+Highlights
+==========
+
+* ``cffi`` is officially supported by PyPy. You can install it normally by
+  using ``pip install cffi`` once you have PyPy installed. The corresponding
+  ``0.4`` version of ``cffi`` has been released.
+
+* ARM is now an officially supported processor architecture.
+  PyPy now work on soft-float ARM/Linux builds.  Currently ARM processors
+  supporting the ARMv7 and later ISA that include a floating-point unit are
+  supported.
+
+* This release contains the latest Python standard library 2.7.3 and is fully
+  compatible with Python 2.7.3.
+
+* It does not however contain hash randomization, since the solution present
+  in CPython is not solving the problem anyway. The reason can be
+  found on the `CPython issue tracker`_.
+
+* ``gc.get_referrers()`` is now faster.
+
+* Various numpy improvements. The list includes:
+
+  * axis argument support in many places
+
+  * full support for fancy indexing
+
+  * ``complex128`` and ``complex64`` dtypes
+
+* `JIT hooks`_ are now a powerful tool to introspect the JITting process that
+  PyPy performs.
+
+* ``**kwds`` usage is much faster in the typical scenario
+
+* operations on ``long`` objects are now as fast as in CPython (from
+  roughly 2x slower)
+
+* We now have special strategies for ``dict``/``set``/``list`` which contain
+  unicode strings, which means that now such collections will be both faster
+  and more compact.

+As announced in the previous release notes for the PyPy 2.0 beta the ARM JIT
+compiler backend branch ``arm-backend-2`` has been merged into the main
+development line and is going to be part of the upcomming release.
+As a general byproduct PyPy should now do a better job supporting non-x86
 architectures such as ARM and the in-progress support for PPC64.
 
+In this post I want to describe a bit more in detail the current state of
+PyPy's ARM support.  Currently we provide two versions of PyPy for ARM, one
+with and one without the JIT compiler.  Currently both target the ARM
+soft-float ABI. And in this post I'm going to focus on the JIT version.

 On ARM, the JIT requires an ARMv7 processor or newer with a VFP unit targeting
 the ARM application profile. Although this sounds like a strong restriction,

http://bitbucket.org/pypy/pypy/changeset/c953de9d810f/

Log:	completely change the strategy for inlining jit_merge_points in the
	caller. The old one did not work in complex cases involving raising
	graphs. In particular, this case did not work:

	def bar(): "something which cannot be inlined and raises"

	@inline_in_portal def foo(): driver.jit_merge_point() return
	bar()

	def fn(): try: foo(): except StopIteration:
	pass

	that's because that the backendopt inliner is not able to inline
	calls to raising graphs inside a try/except block.

	To work around the issue, we put the actual driver.jit_merge_point
	in a separate function, which needs to be called as soon as we enter
	foo(). Then, we move *only* this call from foo() to fn(), and
	finally inline the jit_merge_point in fn().

	Next step is to provide a nice decorator to do everythin
	automatically

+  means that you cannot call any function which has an argument or
+  return value of this type (this would need added support in libffi).
+  You need to write wrapper functions in C, e.g. ``void
+  foo_wrapper(struct my_complex c) { foo(c.real + c.imag*1j); }``, and
+  call ``foo_wrapper`` rather than ``foo`` directly.
 
 * Thread-local variables (access them via getter/setter functions)

+===============
+PyPy 2.0 beta 1
+===============
+
+We're pleased to announce the 2.0 beta 1 release of PyPy. This release is
+not a typical beta, in a sense the stability is the same or better than 1.9
+and can be used in production. It does however include a few performance
+regressions documented below that don't allow us to label is as 2.0 final.
+(It also contains many performance improvements.)
+
+The main features of this release are support for ARM processor and
+compatibility with CFFI. It also includes
+numerous improvements to the numpy in pypy effort, cpyext and performance.
+
+You can download the PyPy 2.0 beta 1 release here:
+
+    http://pypy.org/download.html 
+
+What is PyPy?
+=============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7.3. It's fast (`pypy 2.0 beta 1 and cpython 2.7.3`_
+performance comparison) due to its integrated tracing JIT compiler.
+
+This release supports x86 machines running Linux 32/64, Mac OS X 64 or
+Windows 32. It also supports ARM machines running Linux.
+Windows 64 work is still stalling, we would welcome a volunteer
+to handle that.
+
+.. XXX link
+
+XXX donors info?
+
+Regressions
+===========
+
+Reasons why this is not PyPy 2.0:
+
+* the ``ctypes`` fast path is now slower than it used to be. In PyPy
+  1.9 ``ctypes`` was either incredibly faster or slower than CPython depending whether
+  you hit the fast path or not. Right now it's usually simply slower. We're
+  probably going to rewrite ``ctypes`` using ``cffi``, which will make it
+  universally faster.
+
+* ``cffi`` (an alternative to interfacing with C code) is very fast, but
+  it is missing one optimization that will make it as fast as a native
+  call from C.
+
+* ``numpypy`` lazy computation was disabled for the sake of simplicity.
+  We should reenable this for the final 2.0 release.
+
+Highlights
+==========
+
+* ``cffi`` is officially supported by PyPy. You can install it normally by
+  using ``pip install cffi`` once you have PyPy installed. The corresponding
+  ``0.4`` version of ``cffi`` has been released.
+
+* ARM is now an officially supported processor architecture.
+  PyPy now work on soft-float ARM/Linux builds.  Currently ARM processors
+  supporting the ARMv7 and later ISA that include a floating-point unit are
+  supported.
+
+* This release contains the latest Python standard library 2.7.3 and is fully
+  compatible with Python 2.7.3.
+
+* It does not however contain hash randomization, since the solution present
+  in CPython is not solving the problem anyway. The reason can be
+  found on the `CPython issue tracker`_.
+
+* ``gc.get_referrers()`` is now faster.
+
+* Various numpy improvements. The list includes:
+
+  * axis argument support in many places
+
+  * full support for fancy indexing
+
+  * ``complex128`` and ``complex64`` dtypes
+
+* `JIT hooks`_ are now a powerful tool to introspect the JITting process that
+  PyPy performs.
+
+* ``**kwds`` usage is much faster in the typical scenario
+
+* operations on ``long`` objects are now as fast as in CPython (from
+  roughly 2x slower)
+
+* We now have special strategies for ``dict``/``set``/``list`` which contain
+  unicode strings, which means that now such collections will be both faster
+  and more compact.

Log:	Tweak the implementation of math.log1p in RPython to be more similar
	to math.log and math.log10. Also, this lets us add a special-case,
	backported recently to Python 2.7: math.log1p(-0.0) == -0.0.

+=================================================
+PyPy's VM Approach
+=================================================
+
+:Authors: Armin Rigo, Samuele Pedroni
+:Date: 23 October 2006
+:Location: DLS'06
+
+PyPy
+========================
+
+- Python VM implementation
+  in Python (a well-chosen subset)
+- A translation tool-chain
+- Open source project (MIT license)
+
+VMs are still hard
+========================
+
+It is hard to achieve:
+
+- flexibility
+- maintainability
+- performance (needs
+  dynamic compilation techniques)
+
+Especially with limited resources.
+
+
+Python Case
+===================================
+
+CPython is a straightforward,
+portable VM.
+
+- Some decisions are pervasive:
+  reference counting, single global lock ...
+
+- No dynamic compilation.
+  Performance is limited.
+
+
+- Extensions:
+
+  * *Stackless* (heap-bound recursion,
+    coroutines, serializable continuations)
+
+  * *Psyco* (run-time specializer,
+    interesting results)
+
+
+Python Case (ii)
+===================================
+
+- Extensions...
+
+  ... need to keep track and are hard to maintain.
+  Hard to port Psyco to other architectures.
+
+- The community wants Python to run everywhere:
+  Jython (Java), IronPython (.NET).
+  Lots of effort and duplication.
+
+PyPy's approach
+=================================
+
+*Goal: generate VMs from a single
+high-level description of the language,
+in a retargettable way.*
+
+- Write an interpreter for a dynamic language (Python)
+  in a high-level language (Python)
+
+- Leave out low-level details, favour simplicity
+  and flexibility
+
+- Define a mapping to low-level targets, generating
+  VMs from the interpreter
+
+Mapping to low-level targets
+===============================
+
+- Mechanically translate the interpreter to multiple
+  lower-level targets (C-like, Java, .NET...)
+
+- Insert low-level aspects into the code as required by
+  the target (object layout, memory management...)
+
+- Optionally insert new pervasive features not expressed
+  in the source (continuations, specialization abilities...)
+
+Status of the project
+==========================
+
+Fully compliant interpreter, translatable to C,
+LLVM and the CLR.
+
+Maintainability: following the (fast-paced)
+language evolution is very easy.
+
+Flexibility: we were able to reimplement
+Stackless features without extensive
+changes to the baseline interpreter
+
+Performance: work in-progress,
+2.3 times slower than CPython
+without dynamic compilation (current goal)
+
+... and many experiments at various levels
+
+Translation approach
+==========================
+
+* Refine a subset of your favourite
+  language (e.g. Python) amenable
+  to analysis but expressive enough 
+  to write interpreters in it.
+
+* Write a translation tool-chain
+  from this subset ("RPython")
+  to multiple targets (C-like, .NET, etc.)
+
+* The translation tool-chain should
+  implement (and be configurable to 
+  be) a good mapping from the interpreter
+  to reasonably efficient implementations for 
+  the various targets.
+

+
+
+Type Inference
+=================
+
+- based on abstract interpretation
+
+- fix-point forward propagation
+
+- extensible
+
+Targets as Type Systems
+========================
+
+- RPython types (lists, strings, dicts, instances and classes...)
+  may be too high-level for the target (e.g. in C, structs and pointers)
+
+- approach: reflect the essential aspects
+  of a target as a custom type system
+  into RPython (e.g. C-like types)
+
+::
+
+    STR = GcStruct('rpy_string',
+                      ('hash', Signed),
+                      ('chars', Array(Char)))
+
+Targets as Type Systems (ii)
+================================
+  
+- implement a simulation
+  of the types in normal Python,
+  allowing code like this to run::
+
+    def ll_char_mul(char, length):
+        newstr = malloc(STR, length)
+        newstr.hash = 0
+        for i in range(length):
+            newstr.chars[i] = char
+        return newstr
+
+
+Targets as Type Systems (iii)
+===============================
+
+- extend the type inferencer
+  to understand usages of these types
+
+- use the type system
+  to express how regular, high-level RPython types
+  should be represented 
+  at the level of the target
+
+- write implementation "helper" code (e.g. ``ll_char_mul``)
+  which is again RPython and can be type inferenced
+  and translated
+
+Translation Aspects
+=====================
+
+*Features not present in the source can be
+added during translation:*
+
+- memory management (Boehm, or reference counting
+  by transforming all control flow graphs, or our own
+  GCs - themselves written within the same framework as the
+  RPython "helper" code)
+
+.. GC Pressure blues
+
+Translation Aspects (ii)
+==========================
+
+- continuation capture, implemented by saving the low-level
+  frames' local variables into the heap and back
+
+- work in progress: turning an interpreter into a compiler
+  is a translation aspect too (based on binding-time analysis
+  and partial evaluation, extended to use the techniques of
+  Psyco)
+
+Translation Summary
+===========================
+
+*The translation tool-chain
+has proved effective:*
+
+- low-level details and
+  pervasive decision can be
+  left out of the interpreter
+
+- it can targets at the same time:
+  C, LLVM, the CLR
+  and is open for further backends (JVM in progress)
+
+- it can and has been used
+  in the context of other research
+  projects and spin-off ideas
+  (e.g. a JavaScript backend,
+  compilation of other RPython programs...)
+  
+Website etc.
+=============
+
+* http://codespeak.net/pypy
+* IST EU co-funded project in FP6
+  (7 partners)
+* Thanks
+
+Run-time Specialization
+========================
+
+Previous experience: Psyco
+
+- a "just-in-time specializer" which can transparently
+  accelerate user code
+
+- a C hand-written "generating extension", in the terminology
+  of partial evaluation
+
+- similar to conventional JITs with the additional ability
+  to suspend compilation at any point, and wait for actual
+  run-time information (e.g. type of an object):
+  **promotion**.
+
+A Specializer as an Aspect
+==========================================
+
+General idea (the devil is in the details):
+
+- Transform the flowgraphs of the interpreter
+  into a compiler, using the type inference
+  framework to do binding-time analysis (runtime/
+  compile-time) based on a few hints.
+
+- Special hints to insert and control promotion.
+
+- We think that promotion is the key to making
+  it practical for large interpreters and complex
+  semantics.
+
+This is what we are working on right now.

+Translation Diagram
+=========================
+
+.. image:: image/arch-translation.png
+   :align: center
+
+Self-hosted JITs
+===========================
+
+- they work: Jikes VM
+- the language semantics need to
+  be captured into a good compiler
+- good means the resulting VM
+  should be fast enough
+- target hardware CPUs
+- lots of effort still, and hard
+  to reuse for another language
+
+Target platform VMs (JVM, CLR)
+==============================
+
+- semantics mismatch (e.g.
+  lookup) can result in speed penalty
+  or unnatural code
+
+- how to obliviously layer dynamic
+  compilation on top of a JIT
+  is effectively an open problem
+
+- urge to tweak the underlying VM
+
+- coding in Java, C#: not expressive
+  enough, same risks of inflexibility,
+  hard to revert pervasive decisions
+
+Open Virtual Machines
+==========================
+
+Reconfigurable at run time to run 
+specific languages.
+
+- Open research area.
+
+- Large design space.
+
+- What are the best primitives?
+
+- Likely same trade-offs in
+  more acute form: need sharp tools.
+
+GC Pressure
+======================
+
+RPython is still a garbage collected language.
+
+Large allocation rate from interpreter objects
+(boxes, frames) but easily temporary objects
+too.
+
+Good allocation removal optimizations
+and memory management very much needed.

+* most Python benchmarks run much faster than with CPython or Psyco
+
+
+    what pypy-c is (project started in 2003, now 200KLoc + 150KLoc tests)
+    (2 years U.E. (~2005-2007) + 2 years Germany+Sweden (2010-running))
+
+    PyPy 1.4.1 supports Python 2.5; but we are almost done with support
+    for Python 2.7, which will be PyPy 1.5
+
+    boring demo (multi-line editing)
+
+    speeeeeeeeed
+
+    http://speed.pypy.org/
+
+    but underline *benchmarks* here: it's typically programs that repeatedly
+    do similar things for at least 10-20 seconds.
+
+    mention also memory usage
+
+
+* the real-world PyPy compiler toolchain itself (200 KLocs) runs twice as fast
+
+
+    "extreme" example: big program, very unfriendly to our approach of
+    tracing JITs
+
+
+* already supports 64bit and is in the process of supporting ARM
+
+
+    pypy-c on 64bits
+
+    (pypy-c on ARM -- jitted but slower so far (missing JIT+GC integration))
+
+
+* full compatibility with  CPython (more than Jython/IronPython)
+* new "cpyext" layer which integrates existing CPython C extensions
+
+
+    the main issue is that C extension modules don't all work out of the box
+
+    but some do (slowly (which may matter or not))
+
+    the core supports "the full language", which is CPython minus some
+    small number of issues; the most visible ones are related to refcounts
+    (ends up closer than Jython/IronPython)
+
+
+* full (and JIT-ed) ctypes support to call C libraries from Python
+* supports Stackless Python (in-progress)
+* an experimental super-fast JIT-compilation of calls to C++ libraries
+
+
+    this is all experimental
+
+
+* architecture
+
+
+    interpreter written in Python (actually RPython, a subset)
+
+    gets "translated" to C code
+
+    various "aspects" are added during translation to C, like
+    the GC and the JIT
+
+    it's a tracing JIT (expand...?)

+=======================
+
+There are a few things that did not make it to the 2.0 beta 1, which
+are being actively worked on. Greenlets support in the JIT is one
+that we would like to have before 2.0 final. Two important items that
+will not make it to 2.0, but are being actively worked on, are:
+
+* Faster JIT warmup time.
+
+* Software Transactional Memory.

+## Implementation of PyBytesObject
+## ================================
+##
+## The problem
+## -----------
+##
+## PyBytes_AsString() must return a (non-movable) pointer to the underlying
+## buffer, whereas pypy strings are movable.  C code may temporarily store
+## this address and use it, as long as it owns a reference to the PyObject.
+## There is no "release" function to specify that the pointer is not needed
+## any more.
+##
+## Also, the pointer may be used to fill the initial value of string. This is
+## valid only when the string was just allocated, and is not used elsewhere.
+##
+## Solution
+## --------
+##
+## PyBytesObject contains two additional members: the size and a pointer to a
+## char buffer; it may be NULL.
+##
+## - A string allocated by pypy will be converted into a PyBytesObject with a
+##   NULL buffer.  The first time PyBytes_AsString() is called, memory is
+##   allocated (with flavor='raw') and content is copied.
+##
+## - A string allocated with PyBytes_FromStringAndSize(NULL, size) will
+##   allocate a PyBytesObject structure, and a buffer with the specified
+##   size, but the reference won't be stored in the global map; there is no
+##   corresponding object in pypy.  When from_ref() or Py_INCREF() is called,
+##   the pypy string is created, and added to the global map of tracked
+##   objects.  The buffer is then supposed to be immutable.
+##
+## - _PyBytes_Resize() works only on not-yet-pypy'd strings, and returns a
+##   similar object.
+##
+## - PyBytes_Size() doesn't need to force the object.
+##
+## - There could be an (expensive!) check in from_ref() that the buffer still
+##   corresponds to the pypy gc-managed string.

-    jitdriver_name is the name of this particular jitdriver, 'pypyjit' is

-    loop_type can be either `loop` `entry_bridge` or `bridge`
-    in case loop is not `bridge`, greenkey will be a tuple of constants
-    or a string describing it.

+PyPy San Francisco Sprint Dec 1st - Dec 2nd 2012
+================================================
+
+The next PyPy sprint will be in San Francisco, California. It is a
+public sprint, suitable for newcomers. It will run on Saturday December 1st and
+Sunday December 2nd. The goals for the sprint are continued work towards the
+2.0 release as well as code cleanup, we of course welcome any topic which
+contributors are interested in working on.
+
+Some other possible topics are:
+
+* running your software on PyPy
+
+* work on PyPy's numpy (status__)
+
+* work on STM (status__)
+
+* JIT improvements
+
+* any exciting stuff you can think of
+
+If there are newcomers, we'll run the usual introduction to hacking on
+PyPy.
+
+.. __: http://morepypy.blogspot.ch/2012/09/numpy-on-pypy-status-update.html
+.. __: http://mail.python.org/pipermail/pypy-dev/2012-September/010513.html

+
+Location
+--------
+
+The sprint will be held at the Rackspace Office:
+
+620 Folsom St, Ste 100
+San Francisco

Log:	cpyext now use the Python3 way to declare builtin modules!
	Surprisingly easy change.

	Only array.c was ported to the new scheme, it's now an exact copy
	from CPython Modules/arraymodule.c. All other test modules need to
	be migrated.

+PyPy 2.0 beta 1
+===============
+
+We're pleased to announce the 2.0 beta 1 release of PyPy. This release is
+not a typical beta, in a sense the stability is the same or better than 1.9
+and can be used in production. It does however include a few performance
+regressions documented below that don't allow us to label is as 2.0 final.
+(It also contains many performance improvements.)
+
+The main features of this release are support for ARM processor and
+compatibility with CFFI. It also includes
+numerous improvements to the numpy in pypy effort, cpyext and performance.
+
+You can download the PyPy 2.0 beta 1 release here:
+
+    http://pypy.org/download.html 
+
+What is PyPy?
+=============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7.3. It's fast (`pypy 2.0 beta 1 and cpython 2.7.3`_
+performance comparison) due to its integrated tracing JIT compiler.
+
+This release supports x86 machines running Linux 32/64, Mac OS X 64 or
+Windows 32. It also supports ARM machines running Linux.
+Windows 64 work is still stalling, we would welcome a volunteer
+to handle that.
+
+.. _`pypy 2.0 beta 1 and cpython 2.7.3`: http://bit.ly/USXqpP
+
+How to use PyPy?
+================
+
+We suggest using PyPy from a `virtualenv`_. Once you have a virtualenv
+installed, you can follow instructions from `pypy documentation`_ on how
+to proceed. This document also covers other `installation schemes`_.
+
+.. _`pypy documentation`: http://doc.pypy.org/en/latest/getting-started.html#installing-using-virtualenv
+.. _`virtualenv`: http://www.virtualenv.org/en/latest/
+.. _`installation schemes`: http://doc.pypy.org/en/latest/getting-started.html#installing-pypy
+.. _`PyPy and pip`: http://doc.pypy.org/en/latest/getting-started.html#installing-pypy
+
+Regressions
+===========
+
+Reasons why this is not PyPy 2.0:
+
+* the ``ctypes`` fast path is now slower than it used to be. In PyPy
+  1.9 ``ctypes`` was either incredibly faster or slower than CPython depending whether
+  you hit the fast path or not. Right now it's usually simply slower. We're
+  probably going to rewrite ``ctypes`` using ``cffi``, which will make it
+  universally faster.
+
+* ``cffi`` (an alternative to interfacing with C code) is very fast, but
+  it is missing one optimization that will make it as fast as a native
+  call from C.
+
+* ``numpypy`` lazy computation was disabled for the sake of simplicity.
+  We should reenable this for the final 2.0 release.
+
+Highlights
+==========
+
+* ``cffi`` is officially supported by PyPy. You can install it normally by
+  using ``pip install cffi`` once you have installed `PyPy and pip`_.
+  The corresponding ``0.4`` version of ``cffi`` has been released.
+
+* ARM is now an officially supported processor architecture.
+  PyPy now work on soft-float ARM/Linux builds.  Currently ARM processors
+  supporting the ARMv7 and later ISA that include a floating-point unit are
+  supported.
+
+* This release contains the latest Python standard library 2.7.3 and is fully
+  compatible with Python 2.7.3.
+
+* It does not however contain hash randomization, since the solution present
+  in CPython is not solving the problem anyway. The reason can be
+  found on the `CPython issue tracker`_.
+
+* ``gc.get_referrers()`` is now faster.
+
+* Various numpy improvements. The list includes:
+
+  * axis argument support in many places
+
+  * full support for fancy indexing
+
+  * ``complex128`` and ``complex64`` dtypes
+
+* `JIT hooks`_ are now a powerful tool to introspect the JITting process that
+  PyPy performs.
+
+* ``**kwds`` usage is much faster in the typical scenario
+
+* operations on ``long`` objects are now as fast as in CPython (from
+  roughly 2x slower)
+
+* We now have special strategies for ``dict``/``set``/``list`` which contain
+  unicode strings, which means that now such collections will be both faster
+  and more compact.
+
+.. _`cpython issue tracker`: http://bugs.python.org/issue14621
+.. _`jit hooks`: http://doc.pypy.org/en/latest/jit-hooks.html
+
+Things we're working on
+=======================
+
+There are a few things that did not make it to the 2.0 beta 1, which
+are being actively worked on. Greenlets support in the JIT is one
+that we would like to have before 2.0 final. Two important items that
+will not make it to 2.0, but are being actively worked on, are:
+
+* Faster JIT warmup time.
+
+* Software Transactional Memory.

Log:	Merge branch remove-PYPY_NOT_MAIN_FILE The support files for the C
	platform are now properly split into header and implementation
	files. Like everywhere else.

	Also removed code duplication in genc.py, between one-file-fits-all
	mode and separate C files named after the RPython module name.

+Per-thread data ("key") support.
+
+Use PyThread_create_key() to create a new key.  This is typically shared
+across threads.
+
+Use PyThread_set_key_value(thekey, value) to associate void* value with
+thekey in the current thread.  Each thread has a distinct mapping of thekey
+to a void* value.  Caution:  if the current thread already has a mapping
+for thekey, value is ignored.
+
+Use PyThread_get_key_value(thekey) to retrieve the void* value associated
+with thekey in the current thread.  This returns NULL if no value is
+associated with thekey in the current thread.
+
+Use PyThread_delete_key_value(thekey) to forget the current thread's associated
+value for thekey.  PyThread_delete_key(thekey) forgets the values associated
+with thekey across *all* threads.
+
+While some of these functions have error-return values, none set any
+Python exception.
+
+None of the functions does memory management on behalf of the void* values.
+You need to allocate and deallocate them yourself.  If the void* values
+happen to be PyObject*, these functions don't do refcount operations on
+them either.
+
+The GIL does not need to be held when calling these functions; they supply
+their own locking.  This isn't true of PyThread_create_key(), though (see
+next paragraph).
+
+There's a hidden assumption that PyThread_create_key() will be called before
+any of the other functions are called.  There's also a hidden assumption
+that calls to PyThread_create_key() are serialized externally.

+Things we're working on
+=======================
+
+There are a few things that did not make it to the 2.0 beta 1, which
+are being actively worked on. Greenlets support in the JIT is one
+that we would like to have before 2.0 final. Two important items that
+will not make it to 2.0, but are being actively worked on, are:
+
+* Faster JIT warmup time.
+
+* Software Transactional Memory.

Log:	Issue 1323: don't use the PTHREAD_*_INITIALIZER macros. They might
	initialize the mutexes and condition variables, but after a fork(),
	on some systems, these become completely broken. Instead, always
	assume they contain garbage and initialize them properly.

	This fixes test_threading.test_3_join_in_forked_from_thread on OS/X.

 PyPy's bytearray type is very inefficient. It would be an interesting
 task to look into possible optimizations on this.
 
+Implement copy-on-write list slicing
+------------------------------------
+
+The idea is to have a special implementation of list objects which is used
+when doing ``myslice = mylist[a:b]``: the new list is not constructed
+immediately, but only when (and if) ``myslice`` or ``mylist`` are mutated.

 Numpy improvements
