+======================
+PyPy 2.0 alpha for ARM
+======================
+
+Hello.
+
+We're pleased to announce an alpha release of PyPy 2.0 for ARM. This is mostly
+a technology preview, as we know the JIT is not yet stable enough for the
+full release. However please try your stuff on ARM and report back.
+
+This is the first release that supports a range of ARM devices - anything
+with ARMv6 (that supports VFP, like raspberry pi) or ARMv7 (soft- or hard-float)
+should work.
+
+This release comes with a list of limitations, consider it alpha quality,
+not suitable for production:
+
+* stackless support does not work
+
+* assembler produced is not always correct, but we successfully managed to
+  run our extensive benchmark suite, so most stuff should work
+
+You can download the PyPy 2.0 alpha ARM release here:
+
+    http://pypy.org/download.html 
+
+Part of the work was sponsored by the `Raspberry Pi foundation`_.
+
+.. _`Raspberry Pi foundation`: http://www.raspberrypi.org/
+
+What is PyPy?
+=============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7.3. It's fast due to its integrated tracing JIT compiler.
+
+This release supports ARM machines running Linux 32bit. Both ``armel``
+and ``armhf`` builds are provided.
+
+Benchmarks
+==========
+
+Everybody loves benchmarks. Here is a table of our benchmark suite (we don't
+provide it yet on http://speed.pypy.org, unfortunately).
+
+This is a comparison of Cortex A9 processor with 4M cache and Xeon XXX fill in

+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`_.

Log:	Fix the failing tests added in f81be71175fe:

	- support for singlefloat return values

	- if the backend says it doesn't support some of the types, don't
	crash with a KeyError

	Moreover, avoids casting a real longlong temporarily into a float.
	This is frowned upon by now, because a small fraction of longlongs
	don't cast correctly to float and back.

+============================
+PyPy 2.0 - Einstein Sandwich
+============================
+
+We're pleased to announce PyPy 2.0. This is a stable release that brings
+swath of bugfixes, small performance improvements and compatibility fixes.
+
+You can download the PyPy 2.0 release here:
+
+    http://pypy.org/download.html
+
+Two biggest changes since PyPy 1.9 are:
+
+* stackless is now supported including greenlets, which means eventlet
+  and gevent should work (but read below about gevent)
+
+* PyPy now contains a release 0.6 of `cffi`_ as a builtin module, which
+  is preferred way of calling C from Python that works well on PyPy
+
+.. _`cffi`: http://cffi.readthedocs.org
+
+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 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.  Windows 64 work is still stalling, we would welcome a volunteer
+to handle that. ARM support is on the way and we're expecting to release
+an alpha ARM version shortly.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+* Stackless including greenlets should work. For gevent, you need to check
+  out `pypycore`_ and use `pypy-hacks`_ branch of gevent.
+
+* cffi is not a module included with PyPy. It's a preferred way of calling
+  C from Python that works on PyPy.
+
+* Callbacks from C are now JITted, which means XML parsing is much faster
+
+* A lot of speed improvements in various language corners, most of them small,
+  but speeding up a particular corner a lot
+
+* A lot of stability issues fixed
+
+.. _`pypycore`: https://github.com/gevent-on-pypy/pypycore/

	"Answer a Float that best approximates the value of the receiver.
	This algorithm is optimized to process only the significant digits of a LargeInteger.
	And it does honour IEEE 754 round to nearest even mode in case of excess precision (see details below)."
	
	"How numbers are rounded in IEEE 754 default rounding mode:
	A shift is applied so that the highest 53 bits are placed before the floating point to form a mantissa.
	The trailing bits form the fraction part placed after the floating point.
	This fractional number must be rounded to the nearest integer.
	If fraction part is 2r0.1, exactly between two consecutive integers, there is a tie.
	The nearest even integer is chosen in this case.
	Examples (First 52bits of mantissa are omitted for brevity):
	2r0.00001 is rounded downward to 2r0
	2r1.00001 is rounded downward to 2r1
	2r0.1 is a tie and rounded to 2r0 (nearest even)
	2r1.1 is a tie and rounded to 2r10 (nearest even)
	2r0.10001 is rounded upward to 2r1
	2r1.10001 is rounded upward to 2r10
	Thus, if the next bit after floating point is 0, the mantissa is left unchanged.
	If next bit after floating point is 1, an odd mantissa is always rounded upper.
	An even mantissa is rounded upper only if the fraction part is not a tie."
	
	"Algorihm details:
	The floating point hardware can perform the rounding correctly with several excess bits as long as there is a single inexact operation.
	This can be obtained by splitting the mantissa plus excess bits in two part with less bits than Float precision.
	Note 1: the inexact flag in floating point hardware must not be trusted because in some cases the operations would be exact but would not take into account some bits that were truncated before the Floating point operations.
	Note 2: the floating point hardware is presumed configured in default rounding mode."

The compiler accepts Smalltalk source code and compiles it with respect to a given class. The user of the compiler supplies a context so that temporary variables are accessible during compilation. If there is an error, a requestor (usually a kind of StringHolderController) is sent the message notify:at:in: so that the error message can be displayed. If there is no error, then the result of compilation is a MethodNode, which is the root of a parse tree whose nodes are kinds of ParseNodes. The parse tree can be sent messages to (1) generate code for a CompiledMethod (this is done for compiling methods or evaluating expressions); (2) pretty-print the code (for formatting); or (3) produce a map from object code back to source code (used by debugger program-counter selection).

+TODO for the python3 test suite:
 
-* ARM
+* test_decimal:
+   In py3k, hash(-1) is now -2 (probably as an optimisation, because
+   PyObject_Hash() return -1 on exception).
+   It's important to be compatible, since other classes like Decimal
+   and Fractions have to return the same hashes for equivalent values.
+   IOW: int.__hash__ is part of the Python language specification.
+
+* test_fractions
+* test_numeric_tower
+   float.__hash__ has changed as well.
+
+* test_float
+   nan = float('nan');  assert nan in [nan]
+   This has always been true in CPython, it is now guaranteed that the
+   containers use the "is" operator as an optimization.
+   Difficult in pypy because optimized containers are arrays of
+   unwrapped doubles. A possible solution is to special-case nan in
+   FloatListStrategy.unwrap().
+
+* test_memoryview
+   Needs bytes/str changes. Probably easy.
+
+* test_peepholer
+   'a in [1,2,3]' is rewritten as 'a in (1, 2, 3)'
+   and the tuple is a prebuilt constant.
+   Likewise, a set becomes a frozenset.
+
+* test_pep263
+   Tracebacks should be able to print unicode source code.
+
+* test_sqlite
+   (Probably easy) Ports of CPython changeset fc6f90545cb4 and PyPy
+   48d194e3ac07.
+
+* test_sys
+* test_threading:
+   Missing sys.getswitchinterval().
+   We would be interesting to implement the new thread switching
+   logic, it's a lot of work though.

+============================
+PyPy 2.0 - Einstein Sandwich
+============================
+
+We're pleased to announce PyPy 2.0. This is a stable release that brings
+a swath of bugfixes, small performance improvements and compatibility fixes.
+
+You can download the PyPy 2.0 release here:
+
+    http://pypy.org/download.html
+
+The two biggest changes since PyPy 1.9 are:
+
+* stackless is now supported including greenlets, which means eventlet
+  and gevent should work (but read below about gevent)
+
+* PyPy now contains release 0.6 of `cffi`_ as a builtin module, which
+  is preferred way of calling C from Python that works well on PyPy
+
+.. _`cffi`: http://cffi.readthedocs.org
+
+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 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.  Windows 64 work is still stalling, we would welcome a volunteer
+to handle that. ARM support is on the way and we're expecting to release
+an alpha ARM version shortly.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+* Stackless including greenlets should work. For gevent, you need to check
+  out `pypycore`_ and use the `pypy-hacks`_ branch of gevent.
+
+* cffi is now a module included with PyPy.  (`cffi`_ also exists for
+  CPython; the two versions should be fully compatible.)  It is the
+  preferred way of calling C from Python that works on PyPy.
+
+* Callbacks from C are now JITted, which means XML parsing is much faster.
+
+* A lot of speed improvements in various language corners, most of them small,
+  but speeding up some particular corners a lot.
+
+* The JIT was refactored to emit machine code which manipulates a "frame"
+  that lives on the heap rather than on the stack.  This is what makes
+  Stackless work, and it could bring another future speed-up (not done yet).
+
+* A lot of stability issues fixed.
+
+.. _`pypycore`: https://github.com/gevent-on-pypy/pypycore/
+.. _`pypy-hacks`: https://github.com/schmir/gevent/tree/pypy-hacks
+
+Cheers,
+fijal, arigo and the PyPy team

 .. branch: set-strategies
+
 Sets now have strategies just like dictionaries. This means a set
 containing only ints will be more compact (and faster)
+
 .. branch: speedup-list-comprehension
+
 The simplest case of list comprehension is preallocating the correct size
 of the list. This speeds up select benchmarks quite significantly.
+
 .. branch: stdlib-unification
+
 The directory "lib-python/modified-2.7" has been removed, and its
 content merged into "lib-python/2.7".
+
 .. branch: step-one-xrange
+
 The common case of a xrange iterator with no step argument specifed
 was somewhat optimized. The tightest loop involving it,
 sum(xrange(n)), is now 18% faster on average.
+
 .. branch: string-NUL
+
 PyPy refuses filenames with chr(0) characters. This is implemented in
 RPython which can enforce no-NUL correctness and propagation, similar
 to const-correctness in C++.

+============================
+PyPy 2.0 - Einstein Sandwich
+============================
+
+We're pleased to announce PyPy 2.0. This is a stable release that brings
+a swath of bugfixes, small performance improvements and compatibility fixes.
+
+You can download the PyPy 2.0 release here:
+
+    http://pypy.org/download.html
+
+The two biggest changes since PyPy 1.9 are:
+
+* stackless is now supported including greenlets, which means eventlet
+  and gevent should work (but read below about gevent)
+
+* PyPy now contains release 0.6 of `cffi`_ as a builtin module, which
+  is preferred way of calling C from Python that works well on PyPy
+
+.. _`cffi`: http://cffi.readthedocs.org
+
+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 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.  Windows 64 work is still stalling, we would welcome a volunteer
+to handle that. ARM support is on the way and we're expecting to release
+an alpha ARM version shortly.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+* Stackless including greenlets should work. For gevent, you need to check
+  out `pypycore`_ and use the `pypy-hacks`_ branch of gevent.
+
+* cffi is now a module included with PyPy.  (`cffi`_ also exists for
+  CPython; the two versions should be fully compatible.)  It is the
+  preferred way of calling C from Python that works on PyPy.
+
+* Callbacks from C are now JITted, which means XML parsing is much faster.
+
+* A lot of speed improvements in various language corners, most of them small,
+  but speeding up some particular corners a lot.
+
+* The JIT was refactored to emit machine code which manipulates a "frame"
+  that lives on the heap rather than on the stack.  This is what makes
+  Stackless work, and it could bring another future speed-up (not done yet).
+
+* A lot of stability issues fixed.
+
+.. _`pypycore`: https://github.com/gevent-on-pypy/pypycore/
+.. _`pypy-hacks`: https://github.com/schmir/gevent/tree/pypy-hacks
+
+Cheers,
+fijal, arigo and the PyPy team

Subject: [pypy-commit] pypy default: Fix copy.copy() on generator objects to
 make sure they get their own
Message-ID: <20130508065411.2EEDA1C021A@cobra.cs.uni-duesseldorf.de>

Changeset: r63906:b3975062187f
Date: 2013-05-08 08:53 +0200
http://bitbucket.org/pypy/pypy/changeset/b3975062187f/

Log:	Fix copy.copy() on generator objects to make sure they get their own
	frame too, rather than sharing it with the original generator (which
	crashes completely). Of limited use (see comments in the test).

       a module that accesses PyPy's :term:`interpreter level`.  The name comes

-       that a) correspond to the known semantics of Python objects, b)
-       extend or twist these semantics, or c) serve whole-program analysis
-       purposes.

Log:	modernize int's hash: it's now x modulo the new HASH_MODULUS. an
	exact port of CPython's impl is tricky for 64bit because it assumes
	HASH_BITS (61) >= rbigint's SHIFT (63), which isn't true on PyPy. so
	our algorithm differs and we calculate the hash via the 'wide' type
	like many rbigint methods

-
-By separating concerns in this way, our implementation

-allows a mix-and-match approach to implementation decisions, including
-many that have historically been outside of a user's control, such as
-target platform, memory and
-threading models, garbage collection strategies, and optimizations applied,
-including whether or not to have a JIT in the first place.
 
 High Level Goals
-================
-
-RPython - the Translation Toolchain
------------------------------------
-
-Traditionally, language interpreters are written in a target platform language
-such as C/Posix, Java or C#.  Each implementation provides
-a fundamental mapping between application source code and the target
-environment.  One of
-the goals of the "all-encompassing" environments, such as the .NET framework
-and to some extent the Java virtual machine, is to provide standardized
-and higher level functionalities in order to support language implementers
-for writing language implementations.
-
-PyPy is experimenting with a more ambitious approach.  We are using a
-subset of the high-level language Python, called RPython_, in which we
-write languages as simple interpreters with few references to and
-dependencies on lower level details.  The `RPython toolchain`_
-produces a concrete virtual machine for the platform of our choice by
-inserting appropriate lower level aspects.  The result can be customized
-by selecting other feature and platform configurations.
-
-Our goal is to provide a possible solution to the problem of language
-implementers: having to write ``l * o * p`` interpreters for ``l``
-dynamic languages and ``p`` platforms with ``o`` crucial design
-decisions.  PyPy aims at making it possible to change each of these
-variables independently such that:
-
-* ``l``: the language that we analyze can be evolved or entirely replaced;
-
-* ``o``: we can tweak and optimize the translation process to produce
-  platform specific code based on different models and trade-offs;
-
-* ``p``: we can write new translator back-ends to target different
-  physical and virtual platforms.
-
-By contrast, a standardized target environment - say .NET -
-enforces ``p=1`` as far as it's concerned.  This helps making ``o`` a
-bit smaller by providing a higher-level base to build upon.  Still,
-we believe that enforcing the use of one common environment
-is not necessary.  PyPy's goal is to give weight to this claim - at least
-as far as language implementation is concerned - showing an approach
-to the ``l * o * p`` problem that does not rely on standardization.
-
-The most ambitious part of this goal is to `generate Just-In-Time
-Compilers`_ in a language-independent way, instead of only translating
-the source interpreter into an interpreter for the target platform.
-This is an area of language implementation that is commonly considered
-very challenging because of the involved complexity.
-
-
-PyPy - the Python Interpreter
------------------------------
+----------------
 
 Our main motivation for developing the translation framework is to
-provide a full featured, customizable, fast_ and `very compliant`_ Python
+provide a full featured, customizable, :ref:`fast <how-fast-is-pypy>` and

-PyPy Architecture
-=================
-
-As you would expect from a project implemented using ideas from the world
-of `Extreme Programming`_, the architecture of PyPy has evolved over time
-and continues to evolve.  Nevertheless, the high level architecture is
-stable. As described above, there are two rather independent basic
-subsystems: the `PyPy Python Interpreter`_ and the `RPython Translation Toolchain`_.
-
-.. _`translation framework`:
-
-RPython Translation Toolchain
------------------------------
-
-The job of the RPython toolchain is to translate RPython_ programs
-into an efficient version of that program for one of the various target
-platforms, generally one that is considerably lower-level than Python.
-
-The approach we have taken is to reduce the level of abstraction of the
-source RPython program in several steps, from the high level down to the
-level of the target platform, whatever that may be.  Currently we
-support two broad flavours of target platforms: the ones that assume a
-C-like memory model with structures and pointers, and the ones that
-assume an object-oriented model with classes, instances and methods (as,
-for example, the Java and .NET virtual machines do).
-
-The RPython toolchain never sees the RPython source code or syntax
-trees, but rather starts with the *code objects* that define the
-behaviour of the function objects one gives it as input.  It can be
-considered as "freezing" a pre-imported RPython program into an
-executable form suitable for the target platform.
-
-The steps of the translation process can be summarized as follows:
-
-* The code object of each source functions is converted to a `control
-  flow graph` by the `Flow Object Space`_.
-
-* The control flow graphs are processed by the Annotator_, which
-  performs whole-program type inference to annotate each variable of
-  the control flow graph with the types it may take at run-time.
-
-* The information provided by the annotator is used by the RTyper_ to
-  convert the high level operations of the control flow graphs into
-  operations closer to the abstraction level of the target platform.
-
-* Optionally, `various transformations`_ can then be applied which, for
-  example, perform optimizations such as inlining, add capabilities
-  such as stackless-style concurrency, or insert code for the
-  `garbage collector`_.
-
-* Then, the graphs are converted to source code for the target platform
-  and compiled into an executable.
-
-This process is described in much more detail in the `document about
-the RPython toolchain`_ and in the paper `Compiling dynamic language
-implementations`_.

 Backends for cppyy
 ==================
 
 The cppyy module needs a backend to provide the C++ reflection information on
 which the Python bindings are build.
 The backend is called through a C-API, which can be found in the PyPy sources

+in: :source:`pypy/module/cppyy/include/capi.h`.
 There are two kinds of API calls: querying about reflection information, which
 are used during the creation of Python-side constructs, and making the actual
 calls into C++.
 The objects passed around are all opaque: cppyy does not make any assumptions
 about them, other than that the opaque handles can be copied.
 Their definition, however, appears in two places: in the C code (in capi.h),
-and on the RPython side (in `capi_types.py`_), so if they are changed, they

 the socket module had some progress, PyPy got faster and work was started to
 expose the internals of our parser and bytecode compiler to the user.

 The third PyPy release is out, with an integrated and translatable
 compiler, speed progress, and now the possibility to translate our
 experimental "Thunk" object space (supporting lazy computed objects)
 with its features preserved.

+
+The Flow Model
+--------------
+
+The :ref:`Flow Object Space <flow-object-space>` is described in the `document
+describing object spaces`_. Here we describe the data structures produced by it,
+which are the basic data structures of the translation
+process.
+
+All these types are defined in :source:`rpython/flowspace/model.py` (which is a rather
+important module in the PyPy source base, to reinforce the point).
+
+The flow graph of a function is represented by the class ``FunctionGraph``.
+It contains a reference to a collection of ``Block``\ s connected by ``Link``\ s.
+
+A ``Block`` contains a list of ``SpaceOperation``\ s.  Each ``SpaceOperation``
+has an ``opname`` and a list of ``args`` and ``result``, which are either
+``Variable``\ s or ``Constant``\ s.
+
+We have an extremely useful PyGame viewer, which allows you to visually
+inspect the graphs at various stages of the translation process (very
+useful to try to work out why things are breaking).  It looks like this:
+
+   .. image:: _static/bpnn_update.png
+
+It is recommended to play with ``python bin/translatorshell.py`` on a few
+examples to get an idea of the structure of flow graphs. The following describes
+the types and their attributes in some detail:
+
+
+``FunctionGraph``
+    A container for one graph (corresponding to one function).
+
+    :startblock:   the first block.  It is where the control goes when the
+                   function is called.  The input arguments of the startblock
+                   are the function's arguments.  If the function takes a
+                   ``*args`` argument, the ``args`` tuple is given as the last
+                   input argument of the startblock.
+
+    :returnblock:  the (unique) block that performs a function return.  It is
+                   empty, not actually containing any ``return`` operation; the
+                   return is implicit.  The returned value is the unique input
+                   variable of the returnblock.
+
+    :exceptblock:  the (unique) block that raises an exception out of the
+                   function.  The two input variables are the exception class
+                   and the exception value, respectively.  (No other block will
+                   actually link to the exceptblock if the function does not
+                   explicitly raise exceptions.)
+
+
+``Block``
+    A basic block, containing a list of operations and ending in jumps to other
+    basic blocks.  All the values that are "live" during the execution of the
+    block are stored in Variables.  Each basic block uses its own distinct
+    Variables.
+
+    :inputargs:   list of fresh, distinct Variables that represent all the
+                  values that can enter this block from any of the previous
+                  blocks.
+
+    :operations:  list of SpaceOperations.
+    :exitswitch:  see below
+
+    :exits:       list of Links representing possible jumps from the end of this
+                  basic block to the beginning of other basic blocks.
+
+    Each Block ends in one of the following ways:
+
+    * unconditional jump: exitswitch is None, exits contains a single Link.
+
+    * conditional jump: exitswitch is one of the Variables that appear in the
+      Block, and exits contains one or more Links (usually 2).  Each Link's
+      exitcase gives a concrete value.  This is the equivalent of a "switch":
+      the control follows the Link whose exitcase matches the run-time value of
+      the exitswitch Variable.  It is a run-time error if the Variable doesn't
+      match any exitcase.
+
+    * exception catching: exitswitch is ``Constant(last_exception)``.  The first
+      Link has exitcase set to None and represents the non-exceptional path.
+      The next Links have exitcase set to a subclass of Exception, and are taken
+      when the *last* operation of the basic block raises a matching exception.
+      (Thus the basic block must not be empty, and only the last operation is
+      protected by the handler.)
+
+    * return or except: the returnblock and the exceptblock have operations set
+      to an empty tuple, exitswitch to None, and exits empty.
+
+
+``Link``
+    A link from one basic block to another.
+
+    :prevblock:  the Block that this Link is an exit of.
+
+    :target:     the target Block to which this Link points to.
+
+    :args:       a list of Variables and Constants, of the same size as the
+                 target Block's inputargs, which gives all the values passed
+                 into the next block.  (Note that each Variable used in the
+                 prevblock may appear zero, one or more times in the ``args``
+                 list.)
+
+    :exitcase:   see above.
+
+    :last_exception: None or a Variable; see below.
+
+    :last_exc_value: None or a Variable; see below.
+
+    Note that ``args`` uses Variables from the prevblock, which are matched to
+    the target block's ``inputargs`` by position, as in a tuple assignment or
+    function call would do.
+
+    If the link is an exception-catching one, the ``last_exception`` and
+    ``last_exc_value`` are set to two fresh Variables that are considered to be
+    created when the link is entered; at run-time, they will hold the exception
+    class and value, respectively.  These two new variables can only be used in
+    the same link's ``args`` list, to be passed to the next block (as usual,
+    they may actually not appear at all, or appear several times in ``args``).
+
+
+``SpaceOperation``
+    A recorded (or otherwise generated) basic operation.
+
+    :opname:  the name of the operation. The Flow Space produces only operations
+              from the list in ``pypy.interpreter.baseobjspace``, but later the
+              names can be changed arbitrarily.
+
+    :args:    list of arguments.  Each one is a Constant or a Variable seen
+              previously in the basic block.
+
+    :result:  a *new* Variable into which the result is to be stored.
+
+    Note that operations usually cannot implicitly raise exceptions at run-time;
+    so for example, code generators can assume that a ``getitem`` operation on a
+    list is safe and can be performed without bound checking.  The exceptions to
+    this rule are: (1) if the operation is the last in the block, which ends
+    with ``exitswitch == Constant(last_exception)``, then the implicit
+    exceptions must be checked for, generated, and caught appropriately; (2)
+    calls to other functions, as per ``simple_call`` or ``call_args``, can
+    always raise whatever the called function can raise --- and such exceptions
+    must be passed through to the parent unless they are caught as above.
+
+
+``Variable``
+    A placeholder for a run-time value.  There is mostly debugging stuff here.
+
+    :name:  it is good style to use the Variable object itself instead of its
+            ``name`` attribute to reference a value, although the ``name`` is
+            guaranteed unique.
+
+
+``Constant``
+    A constant value used as argument to a SpaceOperation, or as value to pass
+    across a Link to initialize an input Variable in the target Block.
+
+    :value:  the concrete value represented by this Constant.
+    :key:    a hashable object representing the value.
+
+    A Constant can occasionally store a mutable Python object.  It represents a
+    static, pre-initialized, read-only version of that object.  The flow graph
+    should not attempt to actually mutate such Constants.

-    with ``exitswitch == Constant(last_exception)``, then the implicit
-    exceptions must be checked for, generated, and caught appropriately; (2)
-    calls to other functions, as per ``simple_call`` or ``call_args``, can
-    always raise whatever the called function can raise --- and such exceptions
-    must be passed through to the parent unless they are caught as above.
-
-
-``Variable``
-    A placeholder for a run-time value.  There is mostly debugging stuff here.
-
-    :name:  it is good style to use the Variable object itself instead of its
-            ``name`` attribute to reference a value, although the ``name`` is
-            guaranteed unique.
-
-
-``Constant``
-    A constant value used as argument to a SpaceOperation, or as value to pass
-    across a Link to initialize an input Variable in the target Block.
-
-    :value:  the concrete value represented by this Constant.
-    :key:    a hashable object representing the value.
-
-    A Constant can occasionally store a mutable Python object.  It represents a
-    static, pre-initialized, read-only version of that object.  The flow graph
-    should not attempt to actually mutate such Constants.

+General
+-------
+
+* make inter-documentation links work
+* work on configuration/options documentation
+* structure documentation and add appropriate toctrees

+  (eg. "Installing PyPy", "Building PyPy from source", "Playing with the
+  RPython Toolchain", "Write your own interpreter in RPython")
+* remove documentation for removed features
+* architecture documents don't really show the separation between PyPy and RPython
+* where should the documentation about coding style etc. be put?
+* update / remove dead links
+
+
+RPython
+-------
+
+* remove duplication between translation.rst and rtyper.rst.
+* rename / move rpython.rst?
+
+
+PyPy

+placeholder value that can appear in further operations.

 For example, if the placeholder ``v1`` is given as the argument to the above
 function, the bytecode interpreter will call ``v2 = space.mul(space.wrap(3),
 v1)`` and then ``v3 = space.add(v2, space.wrap(2))`` and return ``v3`` as the
-result.  During these calls the FlowObjSpace will record a basic block::
+result.  During these calls, the following block is recorded::

+======
+
+langjs is an implementation of javascript programming language, written in
+Python using RPython.
+
+You will need to install some dependencies. You can do it with::
+
+    pip install -r requirements.txt
+
+And make sure you have `PyPy_` on your ``PYTHONPATH``.
+
+To run tests::
+
+    $ PYTHONPATH=. py.test
+

Log:	Remove an obscure feature that's more than a bit broken by design,
	the ability to relax the check of signatures. Rationale is that if
	we have a non-standard graph, we should really not be able to store
	it anywhere. Replace a bit of unroll iterable magic with code
	concatanetion - ugly but works and it's actually more understandable
	(IMO)

 Building PyPy from Source
 =========================
+
+For building PyPy, it is recommended to install a pre-build PyPy first (see
+:doc:`install`). It is possible to build PyPy with CPython, but it will take a
+lot longer to run -- depending on your architecture, between two and three
+times as long.
+
+Even when using PyPy to build PyPy, translation is time-consuming -- 30
+minutes on a fast machine -- and RAM-hungry.  You will need **at least** 2 GB
+of memory on a 32-bit machine and 4GB on a 64-bit machine.
+
+
+Install build-time dependencies
+-------------------------------
+
+To build PyPy on Unix using the C translation backend, you need at least a C
+compiler and ``make`` installed. Further, some optional modules have additional
+dependencies:
+
+cffi, ctypes
+    libffi, pkg-config
+
+zlib
+    libz
+
+bz2
+    libbz2
+
+sqlite3
+    libsqlite3
+
+curses
+    libncurses + cffi dependencies from above
+
+pyexpat
+    libexpat1
+
+_ssl
+    libssl
+
+Make sure to have these libraries (with development headers) installed before
+building PyPy, otherwise the resulting binary will not contain these modules.
+
+On Debian, this is the command to install all build-time dependencies::
+
+    apt-get install gcc make libffi-dev pkg-config libz-dev libbz2-dev \
+    libsqlite3-dev libncurses-dev libexpat1-dev libssl-dev
+
+On Fedora::
+
+    yum install gcc make libffi-devel pkgconfig zlib-devel bzip2-devel \
+    lib-sqlite3-devel ncurses-devel expat-devel openssl-devel
+
+
+Run the translation

+
+    pypy rpython/bin/rpython --opt=2 pypy/goal/targetpypystandalone.py
+
+If everything works correctly this will create an executable ``pypy-c`` in the
+current directory. The executable behaves mostly like a normal Python
+interpreter (see :doc:`cpython differences`).
+
+
+Installation
+------------
+
+PyPy dynamically finds the location of its libraries depending on the location
+of the executable. The directory hierarchy of a typical PyPy installation
+looks like this::
+
+    ./bin/pypy
+    ./include/
+    ./lib_pypy/
+    ./lib-python/2.7
+    ./site-packages/
+
+The hierarchy shown above is relative to a PREFIX directory. PREFIX is
+computed by starting from the directory where the executable resides, and
+"walking up" the filesystem until we find a directory containing ``lib_pypy``
+and ``lib-python/2.7``.
+
+To install PyPy system wide on unix-like systems, it is recommended to put the
+whole hierarchy alone (e.g. in ``/opt/pypy``) and put a symlink to the
+``pypy`` executable into ``/usr/bin`` or ``/usr/local/bin``.
+
+If the executable fails to find suitable libraries, it will report ``debug:
+WARNING: library path not found, using compiled-in sys.path`` and then attempt
+to continue normally. If the default path is usable, most code will be fine.
+However, the ``sys.prefix`` will be unset and some existing libraries assume
+that this is never the case.
+
+
+.. TODO windows

+PyPy is written using the RPython toolchain. RPython enables writing dynamic
+language interpreters in a subset of Python which can be translated to C code
+including an automatically generated JIT for the implemented language. If you
+want to learn more about RPython, see the `RPython website`_.

Subject: [pypy-commit] pypy release-2.0.x: Attempt to fix
 stacklet+thread+asmgcc+callbacks: the ordering
Message-ID: <20130515191956.4F4BB1C02E4@cobra.cs.uni-duesseldorf.de>

Log:	Attempt to fix stacklet+thread+asmgcc+callbacks: the ordering was
	wrong, causing self.belongs_to_current_thread to resolve too early
	as the constant "lambda:True".

+==============================
+PyPy 2.0.1 - Bohr Sm&#248;rrebr&#248;d
+==============================
+
+We're pleased to announce PyPy 2.0.1.  This is a stable bugfix release
+over 2.0.  You can download it here:
+  
+    http://pypy.org/download.html
+
+The fixes are mainly about fatal errors or crashes in our stdlib.  See
+below for more details.
+
+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 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.  Support for ARM is progressing but not bug-free yet.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+- fix an occasional crash in the JIT that ends in `RPython Fatal error:
+  NotImplementedError`__.
+
+- `id(x)` is now always a positive number (expect on int/float/long/complex).
+  This fixes an issue in ``_sqlite.py`` (mostly for 32-bit Linux).
+
+- fix crashes of callback-from-C-functions (with cffi) when used together
+  with Stackless features, on asmgcc (i.e. Linux only).  Now `gevent should
+  work better`__.
+
+- work around an eventlet issue with `socket._decref_socketios()`__.

+==============================
+PyPy 2.0.1 - Bohr Sm&#248;rrebr&#248;d
+==============================
+
+We're pleased to announce PyPy 2.0.1.  This is a stable bugfix release
+over `2.0`_.  You can download it here:
+  
+    http://pypy.org/download.html
+
+The fixes are mainly about fatal errors or crashes in our stdlib.  See
+below for more details.
+
+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 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.  Support for ARM is progressing but not bug-free yet.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+- fix an occasional crash in the JIT that ends in `RPython Fatal error:
+  NotImplementedError`__.
+
+- `id(x)` is now always a positive number (except on int/float/long/complex).
+  This fixes an issue in ``_sqlite.py`` (mostly for 32-bit Linux).
+
+- fix crashes of callback-from-C-functions (with cffi) when used together
+  with Stackless features, on asmgcc (i.e. Linux only).  Now `gevent should
+  work better`__.
+
+- work around an eventlet issue with `socket._decref_socketios()`__.
+
+.. __: https://bugs.pypy.org/issue1482
+.. __: http://mail.python.org/pipermail/pypy-dev/2013-May/011362.html
+.. __: https://bugs.pypy.org/issue1468

+==============================
+PyPy 2.0.1 - Bohr Sm&#248;rrebr&#248;d
+==============================
+
+We're pleased to announce PyPy 2.0.1.  This is a stable bugfix release
+over `2.0`_.  You can download it here:
+  
+    http://pypy.org/download.html
+
+The fixes are mainly about fatal errors or crashes in our stdlib.  See
+below for more details.
+
+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 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.  Support for ARM is progressing but not bug-free yet.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+- fix an occasional crash in the JIT that ends in `RPython Fatal error:
+  NotImplementedError`__.
+
+- `id(x)` is now always a positive number (except on int/float/long/complex).
+  This fixes an issue in ``_sqlite.py`` (mostly for 32-bit Linux).
+
+- fix crashes of callback-from-C-functions (with cffi) when used together
+  with Stackless features, on asmgcc (i.e. Linux only).  Now `gevent should
+  work better`__.
+
+- work around an eventlet issue with `socket._decref_socketios()`__.
+
+.. __: https://bugs.pypy.org/issue1482
+.. __: http://mail.python.org/pipermail/pypy-dev/2013-May/011362.html
+.. __: https://bugs.pypy.org/issue1468

+==============================
+PyPy 2.0.1 - Bohr Sm&#248;rrebr&#248;d
+==============================
+
+We're pleased to announce PyPy 2.0.1.  This is a stable bugfix release
+over `2.0`_.  You can download it here:
+  
+    http://pypy.org/download.html
+
+The fixes are mainly about fatal errors or crashes in our stdlib.  See
+below for more details.
+
+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 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.  Support for ARM is progressing but not bug-free yet.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+- fix an occasional crash in the JIT that ends in `RPython Fatal error:
+  NotImplementedError`__.
+
+- `id(x)` is now always a positive number (except on int/float/long/complex).
+  This fixes an issue in ``_sqlite.py`` (mostly for 32-bit Linux).
+
+- fix crashes of callback-from-C-functions (with cffi) when used together
+  with Stackless features, on asmgcc (i.e. Linux only).  Now `gevent should
+  work better`__.
+
+- work around an eventlet issue with `socket._decref_socketios()`__.
+
+.. __: https://bugs.pypy.org/issue1482
+.. __: http://mail.python.org/pipermail/pypy-dev/2013-May/011362.html
+.. __: https://bugs.pypy.org/issue1468

	"Answer a Float that best approximates the value of the receiver.
	This algorithm is optimized to process only the significant digits of a LargeInteger.
	And it does honour IEEE 754 round to nearest even mode in case of excess precision (see details below)."
	
	"How numbers are rounded in IEEE 754 default rounding mode:
	A shift is applied so that the highest 53 bits are placed before the floating point to form a mantissa.
	The trailing bits form the fraction part placed after the floating point.
	This fractional number must be rounded to the nearest integer.
	If fraction part is 2r0.1, exactly between two consecutive integers, there is a tie.
	The nearest even integer is chosen in this case.
	Examples (First 52bits of mantissa are omitted for brevity):
	2r0.00001 is rounded downward to 2r0
	2r1.00001 is rounded downward to 2r1
	2r0.1 is a tie and rounded to 2r0 (nearest even)
	2r1.1 is a tie and rounded to 2r10 (nearest even)
	2r0.10001 is rounded upward to 2r1
	2r1.10001 is rounded upward to 2r10
	Thus, if the next bit after floating point is 0, the mantissa is left unchanged.
	If next bit after floating point is 1, an odd mantissa is always rounded upper.
	An even mantissa is rounded upper only if the fraction part is not a tie."
	
	"Algorihm details:
	The floating point hardware can perform the rounding correctly with several excess bits as long as there is a single inexact operation.
	This can be obtained by splitting the mantissa plus excess bits in two part with less bits than Float precision.
	Note 1: the inexact flag in floating point hardware must not be trusted because in some cases the operations would be exact but would not take into account some bits that were truncated before the Floating point operations.
	Note 2: the floating point hardware is presumed configured in default rounding mode."

Byte codes for literals are not assigned until the tree-sizing pass of the compiler, because only then is it known which literals are actually needed. I also keep track of sourceCode ranges during parsing and code generation so I can provide an inverse map for the debugger.!

The compiler accepts Smalltalk source code and compiles it with respect to a given class. The user of the compiler supplies a context so that temporary variables are accessible during compilation. If there is an error, a requestor (usually a kind of StringHolderController) is sent the message notify:at:in: so that the error message can be displayed. If there is no error, then the result of compilation is a MethodNode, which is the root of a parse tree whose nodes are kinds of ParseNodes. The parse tree can be sent messages to (1) generate code for a CompiledMethod (this is done for compiling methods or evaluating expressions); (2) pretty-print the code (for formatting); or (3) produce a map from object code back to source code (used by debugger program-counter selection).

Subject: [pypy-commit] pypy default: dictview fixes:
Message-ID: <20130518205023.1796B1C01D1@cobra.cs.uni-duesseldorf.de>

Changeset: r64287:4f5876e9b069
Date: 2013-05-18 13:47 -0700
http://bitbucket.org/pypy/pypy/changeset/4f5876e9b069/

Log:	dictview fixes: o add missing right hand set like ops + tests o
	guard the comparisons w/ set like type checks o CPython viewvalues
	lacks __eq__ (though it likely shouldn't), kill it for now since
	it's tailored to SetLikeDictView/sets comparisons anyway

Subject: [pypy-commit] pypy emit-call-x86: A branch to refactor _emit_call()
 and fix it for call_release_gil().
Message-ID: <20130519093300.5717B1C10FA@cobra.cs.uni-duesseldorf.de>

Author: Armin Rigo <arigo at tunes.org>
Branch: emit-call-x86
Changeset: r64309:ba771143d971
Date: 2013-05-19 11:31 +0200
http://bitbucket.org/pypy/pypy/changeset/ba771143d971/

Log:	A branch to refactor _emit_call() and fix it for call_release_gil().
	The issue is that it's not ok to do any access to ebp when the gil

	those that run more threads than cores. The issue was that a
	call_release_gil instruction compiles to code that still accesses
	ebp/rsp after it released the GIL.

Subject: [pypy-commit] pypy release-2.0.x: Manual merge of emit-call-x86:
 fix for multithreaded programs, particularly
Message-ID: <20130520113803.A47131C0217@cobra.cs.uni-duesseldorf.de>

Author: Armin Rigo <arigo at tunes.org>
Branch: release-2.0.x
Changeset: r64365:f7e4f43c9487
Date: 2013-05-20 13:30 +0200
http://bitbucket.org/pypy/pypy/changeset/f7e4f43c9487/

Log:	Manual merge of emit-call-x86: fix for multithreaded programs,
	particularly those that run more threads than cores. The issue was
	that a call_release_gil instruction compiles to code that still
	accesses ebp/rsp after it released the GIL.

Date: Mon, 20 May 2013 13:52:36 +0200 (CEST)
Subject: [pypy-commit] cffi default: Fix (motivated by a pypy without
 cpyext): if we're using vengine_gen.py, 
Message-ID: <20130520115236.8401A1C1027@cobra.cs.uni-duesseldorf.de>

Author: Armin Rigo <arigo at tunes.org>
Branch: 
Changeset: r1253:617edf867775
Date: 2013-05-20 13:52 +0200
http://bitbucket.org/cffi/cffi/changeset/617edf867775/

Log:	Fix (motivated by a pypy without cpyext): if we're using
	vengine_gen.py, then we should not use imp.find_module() to locate
	our compiled module, because it's actually not a CPython C API
	module at all. Instead, just walk sys.path in that case.

+=========================
+PyPy 2.0.2 - Fermi Panini
+=========================
+
+We're pleased to announce PyPy 2.0.2.  This is a stable bugfix release
+over `2.0`_ and `2.0.1`_.  You can download it here:
+
+    http://pypy.org/download.html
+
+It fixes a crash in the JIT when calling external C functions (with
+ctypes/cffi) in a multithreaded context.
+
+.. _2.0: release-2.0.0.html
+.. _2.0.1: release-2.0.1.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 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.  Support for ARM is progressing but not bug-free yet.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+This release contains only the fix described above.  A crash used to
+occur if all these conditions were true:
+
+- your program is multithreaded;
+
+- it runs on a single-core machine or a heavily-loaded multi-core one;
+
+- it uses ctypes or cffi to issue external calls to C functions.
+
+Cheers,
+arigo et. al. for the PyPy team

+=========================
+PyPy 2.0.2 - Fermi Panini
+=========================
+
+We're pleased to announce PyPy 2.0.2.  This is a stable bugfix release
+over `2.0`_ and `2.0.1`_.  You can download it here:
+
+    http://pypy.org/download.html
+
+It fixes a crash in the JIT when calling external C functions (with
+ctypes/cffi) in a multithreaded context.
+
+.. _2.0: release-2.0.0.html
+.. _2.0.1: release-2.0.1.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 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.  Support for ARM is progressing but not bug-free yet.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+This release contains only the fix described above.  A crash (or wrong
+results) used to occur if all these conditions were true:
+
+- your program is multithreaded;
+
+- it runs on a single-core machine or a heavily-loaded multi-core one;
+
+- it uses ctypes or cffi to issue external calls to C functions.
+
+This was fixed in the branch `emit-call-x86`__ (see the example file
+``bug1.py``).
+
+.. __: https://bitbucket.org/pypy/pypy/commits/7c80121abbf4
+
+Cheers,
+arigo et. al. for the PyPy team

 cppyy: C++ bindings for PyPy
 ============================
 
-The cppyy module provides C++ bindings for PyPy by using the reflection
-information extracted from C++ header files by means of the
-`Reflex package`_.
-For this to work, you have to both install Reflex and build PyPy from source,
-as the cppyy module is not enabled by default.
-Note that the development version of cppyy lives in the reflex-support
-branch.
-As indicated by this being a branch, support for Reflex is still
-experimental.
-However, it is functional enough to put it in the hands of those who want
-to give it a try.
-In the medium term, cppyy will move away from Reflex and instead use
-`cling`_ as its backend, which is based on `llvm`_.
-Although that will change the logistics on the generation of reflection
-information, it will not change the python-side interface.
+The cppyy module creates, at run-time, Python-side classes and functions for
+C++, by querying a C++ reflection system.
+The default system used is `Reflex`_, which extracts the needed information
+from C++ header files.
+Another current backend is based on `CINT`_, and yet another, more important
+one for the medium- to long-term will be based on `cling`_.
+The latter sits on top of `llvm`_'s `clang`_, and will therefore allow the use
+of C++11.
+The work on the cling backend has so far been done only for CPython, but
+bringing it to PyPy is a lot less work than developing it in the first place.

 Motivation
 ==========
 
-The cppyy module offers two unique features, which result in great
-performance as well as better functionality and cross-language integration
-than would otherwise be possible.
-First, cppyy is written in RPython and therefore open to optimizations by the
-JIT up until the actual point of call into C++.
-This means that there are no conversions necessary between a garbage collected
-and a reference counted environment, as is needed for the use of existing
-extension modules written or generated for CPython.
-It also means that if variables are already unboxed by the JIT, they can be
-passed through directly to C++.
-Second, Reflex (and cling far more so) adds dynamic features to C++, thus
-greatly reducing impedance mismatches between the two languages.
-In fact, Reflex is dynamic enough that you could write the runtime bindings
+To provide bindings to another language in CPython, you program to a
+generic C-API that exposes many of the interpreter features.
+With PyPy, however, there is no such generic C-API, because several of the
+interpreter features (e.g. the memory model) are pluggable and therefore
+subject to change.
+Furthermore, a generic API does not allow any assumptions about the calls
+into another language, forcing the JIT to behave conservatively around these
+calls and with the objects that cross language boundaries.
+In contrast, cppyy does not expose an API, but expects one to be implemented
+by a backend.
+It makes strong assumptions about the semantics of the API that it uses and
+that in turn allows the JIT to make equally strong assumptions.
+This is possible, because the expected API is only for providing C++ language
+bindings, and does not provide generic programmability.
+
+The cppyy module further offers two features, which result in improved
+performance as well as better functionality and cross-language integration.
+First, cppyy itself is written in RPython and therefore open to optimizations
+by the JIT up until the actual point of call into C++.
+This means for example, that if variables are already unboxed by the JIT, they
+can be passed through directly to C++.
+Second, a backend such as Reflex (and cling far more so) adds dynamic features
+to C++, thus greatly reducing impedance mismatches between the two languages.
+For example, Reflex is dynamic enough to allow writing runtime bindings
 generation in python (as opposed to RPython) and this is used to create very
 natural "pythonizations" of the bound code.
+As another example, cling allows automatic instantiations of templates.
+
+See this description of the `cppyy architecture`_ for further details.

 Installation
 ============
 
-For now, the easiest way of getting the latest version of Reflex, is by
-installing the ROOT package.
-Besides getting the latest version of Reflex, another advantage is that with
-the full ROOT package, you can also use your Reflex-bound code on `CPython`_.
-`Download`_ a binary or install from `source`_.
-Some Linux and Mac systems may have ROOT provided in the list of scientific
-software of their packager.
-If, however, you prefer a standalone version of Reflex, the best is to get
-this `recent snapshot`_, and install like so::
+There are two ways of using cppyy, and the choice depends on how pypy-c was
+built: the backend can be builtin, or dynamically loadable.
+The former has the disadvantage of requiring pypy-c to be linked with external
+C++ libraries (e.g. libReflex.so), but has the advantage of being faster in
+some cases.
+That advantage will disappear over time, however, with improvements in the
+JIT.
+Therefore, this document assumes that the dynamically loadable backend is
+chosen (it is, by default).
+See the `backend documentation`_.
 
-    $ tar jxf reflex-2012-05-02.tar.bz2
-    $ cd reflex-2012-05-02
-    $ build/autogen
+.. _`backend documentation`: cppyy_backend.html
+
+A standalone version of Reflex that also provides the dynamically loadable
+backend is available for `download`_.
+That version, as well as any other distribution of Reflex (e.g. the one that
+comes with `ROOT`_, which may be part of your Linux distribution as part of
+the selection of scientific software) will also work for a build with the
+builtin backend.
+
+.. _`download`: http://cern.ch/wlav/reflex-2013-04-23.tar.bz2
+.. _`ROOT`: http://root.cern.ch/
+
+Besides Reflex, you probably need a version of `gccxml`_ installed, which is
+most easily provided by the packager of your system.
+If you read up on gccxml, you will probably notice that it is no longer being
+developed and hence will not provide C++11 support.
+That's why the medium term plan is to move to cling.
+Note that gccxml is only needed to generate reflection libraries.
+It is not needed to use them.
+
+.. _`gccxml`: http://www.gccxml.org
+
+To install the standalone version of Reflex, after download::
+

-That's why the medium term plan is to move to `cling`_.
+The usual rules apply: <prefix>/bin needs to be added to the ``PATH`` and
+<prefix>/lib to the ``LD_LIBRARY_PATH`` environment variable.
+For convenience, this document will assume that there is a ``REFLEXHOME``
+variable that points to <prefix>.
+If you downloaded or built the whole of ROOT, ``REFLEXHOME`` should be equal
+to ``ROOTSYS``.

-Next, get the `PyPy sources`_, optionally select the reflex-support branch,
-and build it.
-For the build to succeed, the ``$ROOTSYS`` environment variable must point to
-the location of your ROOT (or standalone Reflex) installation, or the
-``root-config`` utility must be accessible through ``PATH`` (e.g. by adding
-``$ROOTSYS/bin`` to ``PATH``).
-In case of the former, include files are expected under ``$ROOTSYS/include``
-and libraries under ``$ROOTSYS/lib``.
 Then run the translation to build ``pypy-c``::
 
     $ hg clone https://bitbucket.org/pypy/pypy
     $ cd pypy
     $ hg up reflex-support         # optional
-    $ cd pypy/goal
     
     # This example shows python, but using pypy-c is faster and uses less memory
-    $ python ../../rpython/bin/rpython.py -O jit --gcrootfinder=shadowstack targetpypystandalone.py --withmod-cppyy
+    $ python rpython/translator/goal/translate.py --opt=jit pypy/goal/targetpypystandalone --withmod-cppyy

 Reflex support.

+==================
+Backends for cppyy
+==================
+
+The cppyy module needs a backend to provide the C++ reflection information on
+which the Python bindings are build.
+The backend is called through a C-API, which can be found in the PyPy sources
+in: `pypy/module/cppyy/include/capi.h`_.
+There are two kinds of API calls: querying about reflection information, which
+are used during the creation of Python-side constructs, and making the actual
+calls into C++.
+The objects passed around are all opaque: cppyy does not make any assumptions
+about them, other than that the opaque handles can be copied.
+Their definition, however, appears in two places: in the C code (in capi.h),
+and on the RPython side (in `capi_types.py`_), so if they are changed, they
+need to be changed on both sides.
+
+.. _`pypy/module/cppyy/include/capi.h`: https://bitbucket.org/pypy/pypy/src/default/pypy/module/cppyy/include/capi.h
+.. _`capi_types.py`: https://bitbucket.org/pypy/pypy/src/default/pypy/module/cppyy/capi/capi_types.py
+
+There are two places where selections in the RPython code affect the choice
+(and use) of the backend.
+The first is in `pypy/module/cppyy/capi/__init__.py`_::
+
+    # choose C-API access method:
+    from pypy.module.cppyy.capi.loadable_capi import *
+    #from pypy.module.cppyy.capi.builtin_capi import *
+
+The default is the loadable C-API.
+Comment it and uncomment the builtin C-API line, to use the builtin version.
+
+.. _`pypy/module/cppyy/capi/__init__.py`:  https://bitbucket.org/pypy/pypy/src/default/pypy/module/cppyy/capi/__init__.py
+
+Next, if the builtin C-API is chosen, the specific backend needs to be set as
+well (default is Reflex).
+This second choice is in `pypy/module/cppyy/capi/builtin_capi.py`_::
+
+    import reflex_capi as backend
+    #import cint_capi as backend
+
+After those choices have been made, built pypy-c as usual.
+
+.. _`pypy/module/cppyy/capi/builtin_capi.py`:  https://bitbucket.org/pypy/pypy/src/default/pypy/module/cppyy/capi/builtin_capi.py
+
+When building pypy-c from source, keep the following in mind.
+If the loadable_capi is chosen, no further prerequisites are needed.
+However, for the build of the builtin_capi to succeed, the ``ROOTSYS``
+environment variable must point to the location of your ROOT (or standalone
+Reflex in the case of the Reflex backend) installation, or the ``root-config``
+utility must be accessible through ``$PATH`` (e.g. by adding ``$ROOTSYS/bin``
+to ``PATH``).
+In case of the former, include files are expected under ``$ROOTSYS/include``
+and libraries under ``$ROOTSYS/lib``.

+============================
+PyPy 2.0 - Einstein Sandwich
+============================
+
+We're pleased to announce PyPy 2.0. This is a stable release that brings
+a swath of bugfixes, small performance improvements and compatibility fixes.
+PyPy 2.0 is a big step for us and we hope in the future we'll be able to
+provide stable releases more often.
+
+You can download the PyPy 2.0 release here:
+
+    http://pypy.org/download.html
+
+The two biggest changes since PyPy 1.9 are:
+
+* stackless is now supported including greenlets, which means eventlet
+  and gevent should work (but read below about gevent)
+
+* PyPy now contains release 0.6 of `cffi`_ as a builtin module, which
+  is preferred way of calling C from Python that works well on PyPy
+
+.. _`cffi`: http://cffi.readthedocs.org
+
+If you're using PyPy for anything, it would help us immensely if you fill out
+the following survey: http://bit.ly/pypysurvey This is for the developers
+eyes and we will not make any information public without your agreement.
+
+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 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.  Windows 64 work is still stalling, we would welcome a volunteer
+to handle that. ARM support is on the way, as you can see from the recently
+released alpha for ARM.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+* Stackless including greenlets should work. For gevent, you need to check
+  out `pypycore`_ and use the `pypy-hacks`_ branch of gevent.
+
+* cffi is now a module included with PyPy.  (`cffi`_ also exists for
+  CPython; the two versions should be fully compatible.)  It is the
+  preferred way of calling C from Python that works on PyPy.
+
+* Callbacks from C are now JITted, which means XML parsing is much faster.
+
+* A lot of speed improvements in various language corners, most of them small,
+  but speeding up some particular corners a lot.
+
+* The JIT was refactored to emit machine code which manipulates a "frame"
+  that lives on the heap rather than on the stack.  This is what makes
+  Stackless work, and it could bring another future speed-up (not done yet).
+
+* A lot of stability issues fixed.
+
+* Refactoring much of the numpypy array classes, which resulted in removal of
+  lazy expression evaluation. On the other hand, we now have more complete
+  dtype support and support more array attributes.

+- fix an occasional crash in the JIT that ends in `RPython Fatal error:

+- `id(x)` is now always a positive number (except on int/float/long/complex).
+  This fixes an issue in ``_sqlite.py`` (mostly for 32-bit Linux).
+
+- fix crashes of callback-from-C-functions (with cffi) when used together
+  with Stackless features, on asmgcc (i.e. Linux only).  Now `gevent should
+  work better`__.
+
+- work around an eventlet issue with `socket._decref_socketios()`__.

+over `2.0`_ and `2.0.1`_.  You can download it here:

+
+This release contains only the fix described above.  A crash (or wrong
+results) used to occur if all these conditions were true:
+
+- your program is multithreaded;
+
+- it runs on a single-core machine or a heavily-loaded multi-core one;
+
+- it uses ctypes or cffi to issue external calls to C functions.
+
+This was fixed in the branch `emit-call-x86`__ (see the example file
+``bug1.py``).

+=========================
+PyPy 2.0.2 - Fermi Panini
+=========================
+
+We're pleased to announce PyPy 2.0.2.  This is a stable bugfix release
+over `2.0`_ and `2.0.1`_.  You can download it here:
+
+    http://pypy.org/download.html
+
+It fixes a crash in the JIT when calling external C functions (with
+ctypes/cffi) in a multithreaded context.
+
+.. _2.0: release-2.0.0.html
+.. _2.0.1: release-2.0.1.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 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.  Support for ARM is progressing but not bug-free yet.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+This release contains only the fix described above.  A crash (or wrong
+results) used to occur if all these conditions were true:
+
+- your program is multithreaded;
+
+- it runs on a single-core machine or a heavily-loaded multi-core one;
+
+- it uses ctypes or cffi to issue external calls to C functions.
+
+This was fixed in the branch `emit-call-x86`__ (see the example file
+``bug1.py``).
+
+.. __: https://bitbucket.org/pypy/pypy/commits/7c80121abbf4
+
+Cheers,
+arigo et. al. for the PyPy team

+=========================
+PyPy 2.0.2 - Fermi Panini
+=========================
+
+We're pleased to announce PyPy 2.0.2.  This is a stable bugfix release
+over `2.0`_ and `2.0.1`_.  You can download it here:
+
+    http://pypy.org/download.html
+
+It fixes a crash in the JIT when calling external C functions (with
+ctypes/cffi) in a multithreaded context.
+
+.. _2.0: release-2.0.0.html
+.. _2.0.1: release-2.0.1.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 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.  Support for ARM is progressing but not bug-free yet.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+This release contains only the fix described above.  A crash (or wrong
+results) used to occur if all these conditions were true:
+
+- your program is multithreaded;
+
+- it runs on a single-core machine or a heavily-loaded multi-core one;
+
+- it uses ctypes or cffi to issue external calls to C functions.
+
+This was fixed in the branch `emit-call-x86`__ (see the example file
+``bug1.py``).
+
+.. __: https://bitbucket.org/pypy/pypy/commits/7c80121abbf4
+
+Cheers,
+arigo et. al. for the PyPy team

+PyPy has layers. Just like Ogres or onions.
+Those layers help us keep the respective parts separated enough
 to be worked on independently and make the complexity manageable. This is,
 again, just a sanity requirement for such a complex project. For example writing
 a new optimization for the JIT usually does **not** involve touching a Python

+==============================
+PyPy 2.0.1 - Bohr Sm&#248;rrebr&#248;d
+==============================
+
+We're pleased to announce PyPy 2.0.1.  This is a stable bugfix release
+over `2.0`_.  You can download it here:
+  
+    http://pypy.org/download.html
+
+The fixes are mainly about fatal errors or crashes in our stdlib.  See
+below for more details.
+
+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 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.  Support for ARM is progressing but not bug-free yet.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+- fix an occasional crash in the JIT that ends in `RPython Fatal error:
+  NotImplementedError`__.
+
+- `id(x)` is now always a positive number (except on int/float/long/complex).
+  This fixes an issue in ``_sqlite.py`` (mostly for 32-bit Linux).
+
+- fix crashes of callback-from-C-functions (with cffi) when used together
+  with Stackless features, on asmgcc (i.e. Linux only).  Now `gevent should
+  work better`__.
+
+- work around an eventlet issue with `socket._decref_socketios()`__.

+PyPy 2.0.2 - Fermi Panini
+=========================
+
+We're pleased to announce PyPy 2.0.2.  This is a stable bugfix release
+over `2.0`_ and `2.0.1`_.  You can download it here:
+
+    http://pypy.org/download.html

+It fixes a crash in the JIT when calling external C functions (with

+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7. It's fast (`pypy 2.0 and cpython 2.7.3`_ performance comparison)
+due to its integrated tracing JIT compiler.

+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+This release contains only the fix described above.  A crash (or wrong
+results) used to occur if all these conditions were true:
+
+- your program is multithreaded;
+
+- it runs on a single-core machine or a heavily-loaded multi-core one;
+
+- it uses ctypes or cffi to issue external calls to C functions.
+
+This was fixed in the branch `emit-call-x86`__ (see the example file
+``bug1.py``).

-"""
-This automaton is designed to be invoked on a Python source string
-before the real parser starts working, in order to find all legal
-'from __future__ import blah'. As soon as something is encountered that
-would prevent more future imports, the analysis is aborted.
-The resulting legal futures are avaliable in self.flags after the
-pass has ended.
-
-Invocation is through get_futures(src), which returns a field of flags, one per
-found correct future import.
-
-The flags can then be used to set up the parser.
-All error detection is left to the parser.
-
-The reason we are not using the regular lexer/parser toolchain is that
-we do not want the overhead of generating tokens for entire files just
-to find information that resides in the first few lines of the file.
-Neither do we require sane error messages, as this job is handled by
-the parser.
-
-To make the parsing fast, especially when the module is translated to C,
-the code has been written in a very serial fashion, using an almost
-assembler like style. A further speedup could be achieved by replacing
-the "in" comparisons with explicit numeric comparisons.

-"""
-This automaton is designed to be invoked on a Python source string
-before the real parser starts working, in order to find all legal
-'from __future__ import blah'. As soon as something is encountered that
-would prevent more future imports, the analysis is aborted.
-The resulting legal futures are avaliable in self.flags after the
-pass has ended.
-
-Invocation is through get_futures(src), which returns a field of flags, one per
-found correct future import.
-
-The flags can then be used to set up the parser.
-All error detection is left to the parser.
-
-The reason we are not using the regular lexer/parser toolchain is that
-we do not want the overhead of generating tokens for entire files just
-to find information that resides in the first few lines of the file.
-Neither do we require sane error messages, as this job is handled by
-the parser.
-
-To make the parsing fast, especially when the module is translated to C,
-the code has been written in a very serial fashion, using an almost
-assembler like style. A further speedup could be achieved by replacing
-the "in" comparisons with explicit numeric comparisons.

Log:	changes needed to make the vm translateable:
	- added intmask call when creating Smallintegers, thus asserting the
	type for the translator
	- added some more such calls
	- restructured primitiveFileStdioHandles to allow calls to module sys
	to be in global scope...

Log:	branch for adding a couple helper format specifiers to
	operationerrfmt: o add %T to return the type name. operationerrfmt
	has to get space w/ an awful hack (but the hack is already necessary
	for py3k) o operationerrfmt now requires a type object for its first
	arg to make this simpler

-"""
-This automaton is designed to be invoked on a Python source string
-before the real parser starts working, in order to find all legal
-'from __future__ import blah'. As soon as something is encountered that
-would prevent more future imports, the analysis is aborted.
-The resulting legal futures are avaliable in self.flags after the
-pass has ended.
-
-Invocation is through get_futures(src), which returns a field of flags, one per
-found correct future import.
-
-The flags can then be used to set up the parser.
-All error detection is left to the parser.
-
-The reason we are not using the regular lexer/parser toolchain is that
-we do not want the overhead of generating tokens for entire files just
-to find information that resides in the first few lines of the file.
-Neither do we require sane error messages, as this job is handled by
-the parser.
-
-To make the parsing fast, especially when the module is translated to C,
-the code has been written in a very serial fashion, using an almost
-assembler like style. A further speedup could be achieved by replacing
-the "in" comparisons with explicit numeric comparisons.

 A demo program can be found in "c3/demo1.c".
 It can be built with "make debug-demo1" or "make build-demo1".
+
+The plan is to use this C code directly with PyPy, and not write
+manually the many calls to the shadow stack and the barrier functions.
+But the manual way is possible too, say when writing a small interpreter
+directly in C.

-This automaton is designed to be invoked on a Python source string
-before the real parser starts working, in order to find all legal
-'from __future__ import blah'. As soon as something is encountered that
-would prevent more future imports, the analysis is aborted.
-The resulting legal futures are avaliable in self.flags after the
-pass has ended.
-
-Invocation is through get_futures(src), which returns a field of flags, one per
-found correct future import.
-
-The flags can then be used to set up the parser.
-All error detection is left to the parser.
-
-The reason we are not using the regular lexer/parser toolchain is that
-we do not want the overhead of generating tokens for entire files just
-to find information that resides in the first few lines of the file.
-Neither do we require sane error messages, as this job is handled by
-the parser.
-
-To make the parsing fast, especially when the module is translated to C,
-the code has been written in a very serial fashion, using an almost
-assembler like style. A further speedup could be achieved by replacing
-the "in" comparisons with explicit numeric comparisons.

+============================
+PyPy 2.0 - Einstein Sandwich
+============================
+
+We're pleased to announce PyPy 2.0. This is a stable release that brings
+a swath of bugfixes, small performance improvements and compatibility fixes.
+PyPy 2.0 is a big step for us and we hope in the future we'll be able to
+provide stable releases more often.
+
+You can download the PyPy 2.0 release here:
+
+    http://pypy.org/download.html
+
+The two biggest changes since PyPy 1.9 are:
+
+* stackless is now supported including greenlets, which means eventlet
+  and gevent should work (but read below about gevent)
+
+* PyPy now contains release 0.6 of `cffi`_ as a builtin module, which
+  is preferred way of calling C from Python that works well on PyPy
+
+.. _`cffi`: http://cffi.readthedocs.org
+
+If you're using PyPy for anything, it would help us immensely if you fill out
+the following survey: http://bit.ly/pypysurvey This is for the developers
+eyes and we will not make any information public without your agreement.
+
+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 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.  Windows 64 work is still stalling, we would welcome a volunteer
+to handle that. ARM support is on the way, as you can see from the recently
+released alpha for ARM.
+
+.. _`pypy 2.0 and cpython 2.7.3`: http://speed.pypy.org
+
+Highlights
+==========
+
+* Stackless including greenlets should work. For gevent, you need to check
+  out `pypycore`_ and use the `pypy-hacks`_ branch of gevent.
+
+* cffi is now a module included with PyPy.  (`cffi`_ also exists for
+  CPython; the two versions should be fully compatible.)  It is the
+  preferred way of calling C from Python that works on PyPy.
+
+* Callbacks from C are now JITted, which means XML parsing is much faster.
+
+* A lot of speed improvements in various language corners, most of them small,
+  but speeding up some particular corners a lot.
+
+* The JIT was refactored to emit machine code which manipulates a "frame"
+  that lives on the heap rather than on the stack.  This is what makes
+  Stackless work, and it could bring another future speed-up (not done yet).
+
+* A lot of stability issues fixed.
+
+* Refactoring much of the numpypy array classes, which resulted in removal of
+  lazy expression evaluation. On the other hand, we now have more complete
+  dtype support and support more array attributes.

+.. _`pypycore`: https://github.com/gevent-on-pypy/pypycore/

-.. branch: refactor-call_release_gil
-Fix a bug which caused cffi to return the wrong result when calling a C
-function which calls a Python callback which forces the frames
-
-.. branch: virtual-raw-mallocs
-JIT optimizations which make cffi calls even faster, by removing the need to
-allocate a temporary buffer where to store the arguments.
-
-.. branch: improve-docs-2
-Improve documents and straighten out links
-
-.. branch: fast-newarray
-Inline the fast path of newarray in the assembler.
-Disabled on ARM until we fix issues.
-
-.. branch: reflex-support
-Allow dynamic loading of a (Reflex) backend that implements the C-API needed
-to provide reflection information
-
-.. branches we don't care about
-.. branch: autoreds

-.. branch: remove-PYPY_NOT_MAIN_FILE
-
-.. branch: missing-jit-operations
-
-.. branch: fix-lookinside-iff-oopspec
-Fixed the interaction between two internal tools for controlling the JIT.
-
-.. branch: inline-virtualref-2
-Better optimized certain types of frame accesses in the JIT, particularly
-around exceptions that escape the function they were raised in.
-
-.. branch: missing-ndarray-attributes
-Some missing attributes from ndarrays
-
-.. branch: cleanup-tests
-Consolidated the lib_pypy/pypy_test and pypy/module/test_lib_pypy tests into
-one directory for reduced confusion and so they all run nightly.
-
-.. branch: unquote-faster
-.. branch: urlparse-unquote-faster
-
-.. branch: signal-and-thread
-Add "__pypy__.thread.signals_enabled", a context manager. Can be used in a
-non-main thread to enable the processing of signal handlers in that thread.

-This automaton is designed to be invoked on a Python source string

-
-Invocation is through get_futures(src), which returns a field of flags, one per

-
-The flags can then be used to set up the parser.
-All error detection is left to the parser.

-The reason we are not using the regular lexer/parser toolchain is that
-we do not want the overhead of generating tokens for entire files just
-to find information that resides in the first few lines of the file.
-Neither do we require sane error messages, as this job is handled by
-the parser.
-
-To make the parsing fast, especially when the module is translated to C,
-the code has been written in a very serial fashion, using an almost
-assembler like style. A further speedup could be achieved by replacing

Subject: [pypy-commit] pypy default: - Use the same way to create longs on
	32bit.
Message-ID: <20130527191143.2F6971C1442@cobra.cs.uni-duesseldorf.de>

Author: Stian Andreassen
Branch: 
Changeset: r64590:6bb363cd7367
Date: 2013-05-27 21:10 +0200
http://bitbucket.org/pypy/pypy/changeset/6bb363cd7367/

Log:	- Use the same way to create longs on 32bit.
	- Remove unnecesary left over special case from _x_sub.
	- Comment out one sign bit from _x_sub. Tests pass without it. Its an
	unsigned. Not a widedigit.

Log:	Changed the priority of eventual spawned processes to 41, because 40
	is the user-priority in newer Squeak images. This breaks the method-
	calling behavior for the mini-images but hopefully re-enables
	benchmarking.

Log:	Merged logging-perf branch.

	This speeds up logging in many (all?) cases by unrolling
	sys._getframe(<constant>) which allows much of the logging code to
	be constant folded. Note that this can still have poor performance
	in the case that something is logged in a long loop, which causes an
	abort due to trace too long. logging traces have a TON of stuff that
	is constant folded in optimizeopt/ which means that their
	unoptimized trace is often an order of magnitude more than their
	optimized length.

 Details of the interactions between STM and the GC
 ==================================================
 
-Below, an "object" means really one version of an object, as allocated
-in memory.  What is from the higher level the "same" object may exist in
-several versions (we say "higher level object" to mean this).  Usually
-these versions are objects in a linked list, chained together with the
-h_revision field in the objects' headers.
+In this document we say "high-level object" to mean an object from the
+point of the user of the library, as opposed to an "object copy", which
+occupies the space of one allocated piece of memory.  One high-level
+object can exist in several copies simultaneously.  This concept of
+"copy" should not be confused with a "revision", which stands for a
+globally consistent copy of all objects.  One revision is the result of
+one transaction.  A program usually has one revision per thread in
+progress, plus any number of older committed revisions.  The committed
+revisions are globally ordered.
 
-Each object is either young or old.  All new objects are allocated
-young.  They become old at the next minor collection.  In the common
-case, objects are allocated in the nursery, and during the next minor
-collection, they are moved outside (if they survive).  The nursery
-contains only young objects, but a few objects outside might be young
-too (e.g. objects too large for the nursery).  (In fact we found out in
-PyPy that it's a good idea to create objects young even if they are
-outside the nursery; otherwise, a program that creates a lot of
-medium-sized objects will quickly exhaust the memory and trigger a lot
-of major collections.)  For the rest of this document we'll ignore young
-objects outside the nursery.
+The object copies exist in one of three main states: they can be
+"private", "protected" or "public".  A copy is private when it belongs
+to the transaction in progress.  When that transaction commits, it
+becomes protected, and remains so as long as it is accessed only by the
+same thread.  A copy becomes public only when another thread requests
+access to it (or, more precisely, "steals" access to it).  Once public,
+a copy is immutable in memory.
+
+From the point of view of the generational GC, each copy is either young
+or old.  All new copies are allocated young.  They become old at the
+next minor collection.  In the common case, copies are allocated in the
+nursery, and during the next minor collection, if they survive, they are
+moved outside.  The nursery contains only young copies, but a few copies
+outside might be young too (e.g. copies of objects too large for the
+nursery).  (In fact we found out in PyPy that it's a good idea to create
+objects young even if they are outside the nursery; otherwise, a program
+that creates a lot of medium-sized objects will quickly exhaust the
+memory and trigger a lot of major collections.)  For the rest of this
+document we'll ignore young copies outside the nursery.
+
+An object that was never seen by a different thread has got at most two
+copies: the first, protected, is the copy at the latest committed
+revision; and the other, private, is the current copy.  If the
+transaction aborts we can forget the private copy and reuse the previous
+protected copy.  If the transaction commits we forget the previous
+protected copy instead; then at this point all private objects become
+protected.  If the object is modified again in the near future, we reuse
+the memory that was occupied by the previous copy to store the next
+private copy.  As a result, each of these two spaces in memory can be
+young or old.  When the GC runs, if any one of these two copies is
+young, only the other copy is kept.  Similarly during major collections,
+only one copy is kept.  So objects no longer modified will eventually
+consume only one space.
+
+The way to share data between threads goes via prebuilt objects, which
+are always public: it is their existence that gives the starting point
+for threads to see each other's objects.  This involves three different
+steps.
+
+1. A thread tries to write to a public object.  This is done by
+allocating a fresh private copy of the public object.  Then writes go to
+the private copy.  If the transaction commits, the private copy becomes
+protected, and the public object is made to point to it (with
+multithread care).  From now on, any access to the public object from
+the same thread will work on the protected object or its future private
+copy.  Any access from a different thread will trigger "stealing", as
+explained next.
+
+2. A thread tries to access a public object but finds that another
+thread has committed changes to it (hereafter called the "foreign
+thread").  Then we "steal" the object.  It is a read-only operation
+performed by peeking on the foreign thread's data.  The operation
+involves making a duplicate of the original copy if it was in the
+foreign thread's nursery, so that no thread ever reads another thread's
+nursery outside of "stealing".  The stolen copy, or the original
+protected copy if it was not young, is then marked as public.  From now
+on nobody is allocated to change the content of this copy, and it
+becomes the current public copy.
+
+3. A subtle but important point about making a public copy is about all
+references stored in the object: if they point to other protected
+objects, then we cannot simply keep them as they are in the public copy.
+In that case, we have to replace these references with pointers to
+public "stubs".  A stub consists of only the header of the object.  It
+is set up in the same way as in point 1 above: it plays the role of an
+"older" public copy of a protected object (although it is not actually
+older of course).  If "we", the thread that just stole the object, then
+try to follow one of the references, we will access one of these stubs,
+and go back to point 1: we will need to steal it again.
+

 Independently, each object can be private or non-private (we used to say

+Implementation
+--------------
+
+This design is made to optimize the hopefully common case: objects we
+handle are mostly private or protected.  We can design in consequence
+the following three points:
+
+1. the extra data stored in the objects (GC flags, and one extra word
+called `h_revision`).
+
+2. the other "off-line" data stored in thread-local data.
+
+3. the read/write barriers.
+
+Point 3 is essential for performance: we want most importantly a read
+barrier that doesn't trigger for the case of reading protected and
+private objects, which is supposed to be the most common case.
+Moreover, it should also not trigger in the basic case of reading a
+never-modified public object.  There are basically three cases:
+
+1. read_barrier(P) = P   [if P is directly a non-modified copy]
+
+2. read_barrier(P) = P->h_revision   [a protected copy with a private one]
+
+3. all other more complex cases, handled by a call.
+
+It is possible to compress the first two cases into C code that GCC
+compiles into two or three assembler instructions, using a conditional
+move.  (Still, it is unclear so far if case 2 is worth inlining at every
+read barrier site, or should be left to the call.)
+
+The case of the write barrier is similar, but differs in the exact
+checks: basically case 1 is only for private objects.  This could be
+done simply by checking a different GC flags.
+

Log:	Fix issue #1492.

	Manual revert in socket.py. This re-introduces the change done in
	2006 in 9db062bb60e3 (anders, implementing explicit refcounting on
	the underlying _socket.socket objects). It reverts a later change
	where, I think for goals of being more Python3-like, the refcounter
	was moved to the class socket._socketobject. However this later
	change is less compatible with CPython 2.x, as shown by eventlet.

	behavior that was previously done with an explicit call to seek(0,
