Log:	A quick hack to show the traces in a hierarchical tree.

	Not sure if this is useful but pushing to a branch incase we decide
	to pick it up later.

	If someone does:

	 * Bring back HTML reset in css, but keep indent on <li>
	 * Remove CACHE.

Log:	Various UI improvements.

	Display loop list as a table. Include columns for length, times
	executes, # of new ops, # of call ops. Display loop description in a
	more palatable manner. Unfloat the menu so it can't cover the traces
	(pet hate).

	Feedback welcomed.

     is handled like a normal function call (this decorator is ignored).
 
     Note also that this optimisation will only take effect if the arguments
-    to the function are "provably constant". By this we mean each argument
+    to the function are proven constant. By this we mean each argument
     is either:
 
-      1) literally constant in the RPython source
+      1) a constant from the RPython source code (e.g. "x = 2")
       2) easily shown to be constant by the tracer
       3) a promoted variable (see @jit.promote)

 As an example of using PyPy from the command line, you could type::
 
-    python pyinteractive.py -c "from test import pystone; pystone.main(10)"
+    python pyinteractive.py --withmod-time -c "from test import pystone; pystone.main(10)"
 
 Alternatively, as with regular Python, you can simply give a
 script name on the command line::
 
-    python pyinteractive.py ../../lib-python/2.7/test/pystone.py 10
+    python pyinteractive.py --withmod-time ../../lib-python/2.7/test/pystone.py 10
+
+The ``--withmod-xxx`` option enables the built-in module ``xxx``.  By
+default almost none of them are, because initializing them takes time.
+If you want anyway to enable all built-in modules, you can use
+``--allworkingmodules``.
 
 See our :doc:`configuration sections <config/index>` for details about what all the commandline
 options do.

+branch gc-incminimark-pinning-improve: 
 Object Pinning is now used in `bz2` and `rzlib` (therefore also affects
 Python's `zlib`). In case the data to compress/decompress is inside the nursery
 (incminimark) it no longer needs to create a non-moving copy of it. This saves
 one `malloc` and copying the data.  Additionally a new GC environment variable
 is introduced (`PYPY_GC_MAX_PINNED`) primarily for debugging purposes.

+Make `*`-unpacking in RPython function calls completely equivalent to passing

+// handler to figure out the instruction that was being executed when
+// the signal-handler was triggered.
+//
+// To get this, we use the ucontext_t argument to the signal-handler
+// callback, which holds the full context of what was going on when
+// the signal triggered.  How to get from a ucontext_t to a Program
+// Counter is OS-dependent.

+// Take the example where function Foo() calls function Bar().  For
+// many architectures, Bar() is responsible for setting up and tearing
+// down its own stack frame.  In that case, it's possible for the
+// interrupt to happen when execution is in Bar(), but the stack frame
+// is not properly set up (either before it's done being set up, or
+// after it's been torn down but before Bar() returns).  In those
+// cases, the stack trace cannot see the caller function anymore.
+//
+// GetPC can try to identify this situation, on architectures where it
+// might occur, and unwind the current function call in that case to
+// avoid false edges in the profile graph (that is, edges that appear
+// to show a call skipping over a function).  To do this, we hard-code
+// in the asm instructions we might see when setting up or tearing
+// down a stack frame.
+//
+// This is difficult to get right: the instructions depend on the
+// processor, the compiler ABI, and even the optimization level.  This
+// is a best effort patch -- if we fail to detect such a situation, or
+// mess up the PC, nothing happens; the returned PC is not used for
+// any further processing.

Log:	RPython really replaces time.time by the version in rtime.py: add
	staticmethod() so that the Python function does not become a method!

+PyPy optimzier module
+===
+
+After finding any trace in a user program, the generated interpreter records the instructions until it encounters a backwards jump. The allow operations found in a trace can be found in `rpython/metainterp/resoperation.py`. An example trace could look like this (syntax is the same as used in the test suit):
+
+   [p0,i0]
+   i1 = int_add(i0)
+   i2 = int_le(i1, 100)
+   guard_true(i2)
+   jump(p0, i1)
+
+The first operation is called a label, the last is the backwards jump. Before the jit backend transforms any trace into a machine code, it tries to transform the trace into an equivalent trace that executes faster. The method `optimize_trace` in `rpython/jit/metainterp/optimizeopt/__init__.py` is the main entry point.
+
+Optimizations are applied in a sequence one after another and the base sequence is as follows:
+
+    intbounds:rewrite:virtualize:string:earlyforce:pure:heap:unroll
+
+Each of the colon separated name has a class attached that is later instantiated as a subclass of `Optimization`. The second class is the `Optimizer` that is derives from the `Optimization` class as well. Most of the optimizations only require a single forward pass. The trace is 'propagated' in to each optimization in the method `propagate_forward`. Instruction by instruction then flows from the first optimization to the last optimization. The method `emit_operation` is called for every operation that is passed to the next optimizer.
+
+A frequently encountered pattern
+---
+
+One pattern that is often used in the optimizer is the binding of operation to a method. `make_dispatcher_method` associates methods with instructions.
+
+    class OptX(Optimization):
+        def prefix_JUMP(self, op):
+            pass # emit, transform, ...
+
+   dispatch_opt = make_dispatcher_method(OptX, 'prefix_', default=OptSimplify.emit_operation)
+   OptX.propagate_forward = dispatch_opt
+   
+
+This ensures that whenever a jump operation is encountered it is routed to the method `prefix_JUMP`.
+
+Rewrite
+---
+
+The second optimization is called 'rewrite' an is commonly also known as strength reduction. A simple example would be that an integer multiplied by 2 is equivalent to the bits shifted to the left once (e.g. x * 2 == x << 1). Not only strength reduction is done in this optimization but also boolean or arithmetic simplifications. Examples would be: x & 0 == 0, x - 0 == x, ... 
+
+Whenever such an operation is encountered (e.g. x & 0), no operation is emitted. Instead the variable of x is made equal to 0 (= `make_equal_to(op.result, 0)`). The variables found in a trace are instances of Box classes that can be found in `rpython/jit/metainterp/history.py`. `OptValue` wraps those variables again and maps the boxes to the optimization values in the optimizer. When a value is made equal, the box in the opt. value. This renders a new value to any further access.
+
+As a result the optimizer must provide the means to access the OptValue instances. Thus it must use methods such as `make_args_key` to retrive the OptValue instances.
+
+OptPure
+---
+
+Is interwoven into the basic optimizer. It saves operations, results, arguments to be known to have pure semantics.
+
+(What does pure really mean? as far as I can tell:) Pure is free of side effects and it is referentially transparent (the operation can be replaced with its value without changing the program semantics). The operations marked as ALWAYS_PURE in `resoperation.py` is a subset of the SIDEEFFECT free operations. Operations such as new, new array, getfield_(raw/gc) are marked of sideeffect free but not as pure.
+
+This can be seen as memoization technique. Once an operation proved to be 'pure' it is saved and should not be recomputed later.
+
+Unroll
+---
+
+A detailed description can be found the paper (see references below). This optimization does not fall into the traditional scheme of one forward pass only. In a nutshell it unrolls the trace _once_, connects the two traces (by inserting parameters into the jump and label of the peeled trace) and uses information to iron out allocations, propagate constants and do any other optimization currently present in the 'optimizeopt' module.
+
+It is prepended all optimizations and thus extends the Optimizer class and unrolls the loop once before it proceeds.

 * Allocation Removal by Partial Evaluation in a Tracing JIT
   Link: - http://www.stups.uni-duesseldorf.de/mediawiki/images/b/b0/Pub-BoCuFiLePeRi2011.pdf
+
+
+Setting user parameters in the jit
+===
+
+It is described often in the documenation that PyPy is a Python program that runs and after a certain point starts to analyse the program (annotate, rtype) and finally generate a c code for a virtual machine to run python programs. Thus at runtime it is very often the case that the program does not provide an implementation of a function, but later insert implementation to call sites. An example for that would be the parameter passing to the jit backend.
+
+`pypy/app_main.py` parses the arguments and provides invokes `set_param` on the internal jit module (`pypy/module/interp_pypy.py`). Some steps iron out some problems on the user side and finally pass it to `rpython/rlib/jit.py`.
+Following the `set_param` calls will lead to an empty method call in `_set_param`. At first glance this is very confusing. There are two things happening while compiling that make create the actual implemenation.
+First an `ExtParam` class is consturcted deriving from `ExtRegistryEntry`. Second, the method is filled with an actual implementation in `rpython/jit/metainterpreter/warmspot.py`. The method `rewrite_set_param_and_get_stats` find methods that call 'jit_marker' (first parameter is 'set_param'). Those functions are rewritten and invoke a `set_param_XXX`. In the program I have not seen a direct invocation of jit_marker yet, but the ExtRegistryEntry (in combination with its meta class) supplies methods to control the annotator. In the case it generates an operation that calls 'jit_marker'. After that the rewrite method is able to find that invocation and exchange the dummy call site with a real python function that sets the parameter.
+
+Test vs Runtime environment
+===
+
+Optimizer module
+---
+
+* The test environment instanciates mostly fake objects for generated objects, or objects that are selected at translation time of pypy. Examples: cpu, jitdriver_sd, descriptors, ...
+For descriptors this was not that obvious to me: `rpython/jit/backend/llgraph/*.py` contains nearly all descriptors, but only for testing purpose. Find the real implementations in `rpython/jit/backend/llsupport/descr.py`.

Log:	separated dependency graph testing from the vectorize optimization
	tests. added more test cases that check fail args of guards
	(extended impl as well) extended the test cases to check that no
	dependency edge duplication is happening added missing vectorize
	field for jiddriver_sd in the test suit for virtualstate (all tests
	passing now)

-PyPy optimzier module
-===
-
-After finding any trace in a user program, the generated interpreter records the instructions until it encounters a backwards jump. The allow operations found in a trace can be found in `rpython/metainterp/resoperation.py`. An example trace could look like this (syntax is the same as used in the test suit):
-
-    [p0,i0]
-    i1 = int_add(i0)
-    i2 = int_le(i1, 100)
-    guard_true(i2)
-    jump(p0, i1)
-
-The first operation is called a label, the last is the backwards jump. Before the jit backend transforms any trace into a machine code, it tries to transform the trace into an equivalent trace that executes faster. The method `optimize_trace` in `rpython/jit/metainterp/optimizeopt/__init__.py` is the main entry point.
-
-Optimizations are applied in a sequence one after another and the base sequence is as follows:
-
-    intbounds:rewrite:virtualize:string:earlyforce:pure:heap:unroll
-
-Each of the colon separated name has a class attached that is later instantiated as a subclass of `Optimization`. The second class is the `Optimizer` that is derives from the `Optimization` class as well. Most of the optimizations only require a single forward pass. The trace is 'propagated' in to each optimization in the method `propagate_forward`. Instruction by instruction then flows from the first optimization to the last optimization. The method `emit_operation` is called for every operation that is passed to the next optimizer.
-
-A frequently encountered pattern
----
-
-One pattern that is often used in the optimizer is the binding of operation to a method. `make_dispatcher_method` associates methods with instructions.
-
-    class OptX(Optimization):
-        def prefix_JUMP(self, op):
-            pass # emit, transform, ...
-
-   dispatch_opt = make_dispatcher_method(OptX, 'prefix_', default=OptSimplify.emit_operation)
-   OptX.propagate_forward = dispatch_opt
-   
-
-This ensures that whenever a jump operation is encountered it is routed to the method `prefix_JUMP`.
-
-Rewrite
----
-
-The second optimization is called 'rewrite' an is commonly also known as strength reduction. A simple example would be that an integer multiplied by 2 is equivalent to the bits shifted to the left once (e.g. x * 2 == x << 1). Not only strength reduction is done in this optimization but also boolean or arithmetic simplifications. Examples would be: x & 0 == 0, x - 0 == x, ... 
-
-Whenever such an operation is encountered (e.g. x & 0), no operation is emitted. Instead the variable of x is made equal to 0 (= `make_equal_to(op.result, 0)`). The variables found in a trace are instances of Box classes that can be found in `rpython/jit/metainterp/history.py`. `OptValue` wraps those variables again and maps the boxes to the optimization values in the optimizer. When a value is made equal, the box in the opt. value. This renders a new value to any further access.
-
-As a result the optimizer must provide the means to access the OptValue instances. Thus it must use methods such as `make_args_key` to retrive the OptValue instances.
-
-OptPure
----
-
-Is interwoven into the basic optimizer. It saves operations, results, arguments to be known to have pure semantics.
-
-(What does pure really mean? as far as I can tell:) Pure is free of side effects and it is referentially transparent (the operation can be replaced with its value without changing the program semantics). The operations marked as ALWAYS_PURE in `resoperation.py` is a subset of the SIDEEFFECT free operations. Operations such as new, new array, getfield_(raw/gc) are marked of sideeffect free but not as pure.
-
-This can be seen as memoization technique. Once an operation proved to be 'pure' it is saved and should not be recomputed later.
-
-Unroll
----
-
-A detailed description can be found the paper (see references below). This optimization does not fall into the traditional scheme of one forward pass only. In a nutshell it unrolls the trace _once_, connects the two traces (by inserting parameters into the jump and label of the peeled trace) and uses information to iron out allocations, propagate constants and do any other optimization currently present in the 'optimizeopt' module.
-
-It is prepended all optimizations and thus extends the Optimizer class and unrolls the loop once before it proceeds.

-
-Setting user parameters in the jit
-===
-
-It is described often in the documenation that PyPy is a Python program that runs and after a certain point starts to analyse the program (annotate, rtype) and finally generate a c code for a virtual machine to run python programs. Thus at runtime it is very often the case that the program does not provide an implementation of a function, but later insert implementation to call sites. An example for that would be the parameter passing to the jit backend.
-
-`pypy/app_main.py` parses the arguments and provides invokes `set_param` on the internal jit module (`pypy/module/interp_pypy.py`). Some steps iron out some problems on the user side and finally pass it to `rpython/rlib/jit.py`.
-Following the `set_param` calls will lead to an empty method call in `_set_param`. At first glance this is very confusing. There are two things happening while compiling that make create the actual implemenation.
-First an `ExtParam` class is consturcted deriving from `ExtRegistryEntry`. Second, the method is filled with an actual implementation in `rpython/jit/metainterpreter/warmspot.py`. The method `rewrite_set_param_and_get_stats` find methods that call 'jit_marker' (first parameter is 'set_param'). Those functions are rewritten and invoke a `set_param_XXX`. In the program I have not seen a direct invocation of jit_marker yet, but the ExtRegistryEntry (in combination with its meta class) supplies methods to control the annotator. In the case it generates an operation that calls 'jit_marker'. After that the rewrite method is able to find that invocation and exchange the dummy call site with a real python function that sets the parameter.
-
-Test vs Runtime environment
-===
-
-Optimizer module
----
-
-* The test environment instanciates mostly fake objects for generated objects, or objects that are selected at translation time of pypy. Examples: cpu, jitdriver_sd, descriptors, ...
-For descriptors this was not that obvious to me: `rpython/jit/backend/llgraph/*.py` contains nearly all descriptors, but only for testing purpose. Find the real implementations in `rpython/jit/backend/llsupport/descr.py`.

Subject: [pypy-commit] pypy vecopt2: enhanced dependency test. no boiler
 plate code to define dependencies (but annotate in the code instead)
Message-ID: <20150505074550.AF3731C080A@cobra.cs.uni-duesseldorf.de>

Author: Richard Plangger <rich at pasra.at>
Branch: vecopt2
Changeset: r77100:4f501c0da147
Date: 2015-03-31 12:15 +0200
http://bitbucket.org/pypy/pypy/changeset/4f501c0da147/

Log:	enhanced dependency test. no boiler plate code to define
	dependencies (but annotate in the code instead) leaf nodes now have
	a dep. edge to jump op correctly redefining variables if they are
	destroyed by a call

Subject: [pypy-commit] pypy vecopt2: tested and adapted the trace optimizer
	for loops.
Message-ID: <20150505074608.082CA1C080A@cobra.cs.uni-duesseldorf.de>

Author: Richard Plangger <rich at pasra.at>
Branch: vecopt2
Changeset: r77115:0b90aa19f600
Date: 2015-04-16 13:01 +0200
http://bitbucket.org/pypy/pypy/changeset/0b90aa19f600/

Log:	tested and adapted the trace optimizer for loops. trace jump targets
	are correctly set and the vec. optimizer avoids the unroller added
	vec_int_signext

Log:	wrapping all parameters passed to the assembler (from regalloc) in
	imm moved try_disable_unroll one layer down to optimize_trace. it is
	now easier to access user parameters in optimzie_trace routine
	(passing warmstate)

Subject: [pypy-commit] pypy vecopt2: weaker guards are stripped from the
	trace
Message-ID: <20150505074623.3683B1C080A@cobra.cs.uni-duesseldorf.de>

Author: Richard Plangger <rich at pasra.at>
Branch: vecopt2
Changeset: r77128:d16c3d437d4e
Date: 2015-05-01 09:43 +0200
http://bitbucket.org/pypy/pypy/changeset/d16c3d437d4e/

Log:	weaker guards are stripped from the trace quick and dirty
	implementation to remove redundant index calculations (j=i+1;k=j+1
	=> j=i+1;k=i+2) consider to move this into the rewrite optimizer (as
	fijal suggested)

+Packaging (preparing for installation)
+--------------------------------------
+
+Packaging is required if you want to install PyPy system-wide, even to
+install on the same machine.  The reason is that doing so prepares a
+number of extra features that cannot be done lazily on a root-installed
+PyPy, because the normal users don't have write access.  This concerns
+mostly libraries that would normally be compiled if and when they are
+imported the first time.
+
+::
+    
+    cd pypy/tool/release
+    ./package.py pypy-VER-PLATFORM
+
+This creates a clean and prepared hierarchy, as well as a ``.tar.bz2``
+with the same content; both are found by default in
+``/tmp/usession-YOURNAME/build/``.  You can then either move the file
+hierarchy or unpack the ``.tar.bz2`` at the correct place.

+    python pyinteractive.py --withmod-time -c "from test import pystone; pystone.main(10)"
 
 Alternatively, as with regular Python, you can simply give a
 script name on the command line::

+The ``--withmod-xxx`` option enables the built-in module ``xxx``.  By
+default almost none of them are, because initializing them takes time.
+If you want anyway to enable all built-in modules, you can use
+``--allworkingmodules``.
 
 See our :doc:`configuration sections <config/index>` for details about what all the commandline
 options do.

+PyPy 2.5.1 - Pineapple Bromeliad
+================================
+
+We're pleased to announce PyPy 2.5.1, Pineapple `Bromeliad`_ following on the heels of 2.5.0
+
+You can download the PyPy 2.5.1 release here:
+
+    http://pypy.org/download.html
+
+We would like to thank our donors for the continued support of the PyPy
+project, and for those who donate to our three sub-projects, as well as our
+volunteers and contributors.  
+We've shown quite a bit of progress, but we're slowly running out of funds.
+Please consider donating more, or even better convince your employer to donate,
+so we can finish those projects! The three sub-projects are:
+
+* `Py3k`_ (supporting Python 3.x): We have released a Python 3.2.5 compatible version
+   we call PyPy3 2.4.0, and are working toward a Python 3.3 compatible version
+
+* `STM`_ (software transactional memory): We have released a first working version,
+  and continue to try out new promising paths of achieving a fast multithreaded Python
+
+* `NumPy`_ which requires installation of our fork of upstream numpy,
+  available `on bitbucket`_

+What is PyPy?
+=============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7. It's fast (`pypy and cpython 2.7.x`_ performance comparison)
+due to its integrated tracing JIT compiler.
+
+This release supports **x86** machines on most common operating systems
+(Linux 32/64, Mac OS X 64, Windows, and OpenBSD),
+as well as newer **ARM** hardware (ARMv6 or ARMv7, with VFPv3) running Linux.
+
+While we support 32 bit python on Windows, work on the native Windows 64
+bit python is still stalling, we would welcome a volunteer
+to `handle that`_.

+
+Highlights 
+==========
+
+* The past months have seen pypy mature and grow, as rpython becomes the goto
+  solution for writing fast dynamic language interpreters. Our separation of
+  Rpython and the python interpreter PyPy is now much clearer in the
+  `PyPy documentation`_  and we now have seperate `RPython documentation`_.
+  Tell us what still isn't clear, or even better help us improve the documentation.
+
+* We merged version 2.7.9 of python's stdlib. From the python release notice:
+
+  * The entirety of Python 3.4's `ssl module`_ has been backported. 
+    See `PEP 466`_ for justification.
+
+  * HTTPS certificate validation using the system's certificate store is now
+    enabled by default. See `PEP 476`_ for details.
+
+  * SSLv3 has been disabled by default in httplib and its reverse dependencies
+    due to the `POODLE attack`_.
+
+  * The `ensurepip module`_ has been backported, which provides the pip
+    package manager in every Python 2.7 installation. See `PEP 477`_.
+
+* The garbage collector now ignores parts of the stack which did not change
+  since the last collection, another performance boost
+
+* errno and LastError are saved around cffi calls so things like pdb will not
+  overwrite it
+
+* We continue to asymptotically approach a score of 7 times faster than cpython
+  on our benchmark suite, we now rank 6.98 on latest runs
+
+* Issues reported with our previous release were resolved_ after reports from users on
+  our issue tracker at https://bitbucket.org/pypy/pypy/issues or on IRC at
+  #pypy.

+
+...and what pypy-stm is not for
+-------------------------------
+
+``pypy-stm`` gives a Python without the GIL.  This means that it is
+useful in situations where the GIL is the problem in the first place.
+(This includes cases where the program can easily be modified to run
+in multiple threads; often, we don't consider doing that precisely
+because of the GIL.)
+
+However, there are plenty of cases where the GIL is not the problem.
+Do not hope ``pypy-stm`` to be helpful in these cases!  This includes
+all programs that use multiple threads but don't actually spend a lot
+of time running Python code.  For example, it may be spending all its
+time waiting for I/O to occur, or performing some long computation on
+a huge matrix.  These are cases where the CPU is either idle, or in
+some C/Fortran library anyway; in both cases, the interpreter (either
+CPython or the regular PyPy) should release the GIL around the
+external calls.  The threads will thus not end up fighting for the
+GIL.

+The core of STM works as a library written in C (see `reference to

+How to write multithreaded programs: the 10'000-feet view
+---------------------------------------------------------
+
+PyPy-STM offers two ways to write multithreaded programs:
+
+* the traditional way, using the ``thread`` or ``threading`` modules,
+  described first__.
+
+* using ``TransactionQueue``, described next__, as a way to hide the
+  low-level notion of threads.
+
+.. __: `Drop-in replacement`_
+.. __: `transaction.TransactionQueue`_
+
+The issues with low-level threads are well known (particularly in other
+languages that don't have GIL-based interpreters): memory corruption,
+deadlocks, livelocks, and so on.  There are alternative approaches to
+dealing directly with threads, like OpenMP_.  These approaches
+typically enforce some structure on your code.  ``TransactionQueue``
+is in part similar: your program needs to have "some chances" of
+parallelization before you can apply it.  But I believe that the scope
+of applicability is much larger with ``TransactionQueue`` than with
+other approaches.  It usually works without forcing a complete
+reorganization of your existing code, and it works on any Python
+program which has got *latent* and *imperfect* parallelism.  Ideally,
+it only requires that the end programmer identifies where this
+parallelism is likely to be found, and communicates it to the system
+using a simple API.

 can execute in parallel, but will commit in some serial order.  They
 appear to behave as if they were completely run in this serialization
 order.
 
 
+transaction.TransactionQueue
+----------------------------
+
+In CPU-hungry programs, we can often easily identify outermost loops
+over some data structure, or other repetitive algorithm, where each
+"block" consists of processing a non-trivial amount of data, and where
+the blocks "have a good chance" to be independent from each other.  We
+don't need to prove that they are actually independent: it is enough
+if they are *often independent* --- or, more precisely, if we *think
+they should be* often independent.
+
+One typical example would look like this, where the function ``func()``
+typically invokes a large amount of code::
+
+    for key, value in bigdict.items():
+        func(key, value)
+
+Then you simply replace the loop with::
+
+    from transaction import TransactionQueue
+
+    tr = TransactionQueue()
+    for key, value in bigdict.items():
+        tr.add(func, key, value)
+    tr.run()
+
+This code's behavior is equivalent.  Internally, the
+``TransactionQueue`` object will start N threads and try to run the
+``func(key, value)`` calls on all threads in parallel.  But note the
+difference with a regular thread-pooling library, as found in many
+lower-level languages than Python: the function calls are not randomly
+interleaved with each other just because they run in parallel.  The
+behavior did not change because we are using ``TransactionQueue``.
+All the calls still *appear* to execute in some serial order.
+
+A typical usage of ``TransactionQueue`` goes like that: at first,
+the performance does not increase.
+In fact, it is likely to be worse.  Typically, this is
+indicated by the total CPU usage, which remains low (closer to 1 than
+N cores).  First note that it is expected that the CPU usage should
+not go much higher than 1 in the JIT warm-up phase: you must run a
+program for several seconds, or for larger programs at least one
+minute, to give the JIT a chance to warm up enough.  But if CPU usage
+remains low even afterwards, then the ``PYPYSTM`` environment variable
+can be used to track what is going on.
+
+Run your program with ``PYPYSTM=logfile`` to produce a log file called
+``logfile``.  Afterwards, use the ``pypy/stm/print_stm_log.py``
+utility to inspect the content of this log file.  It produces output
+like this (sorted by amount of time lost, largest first)::
+
+    10.5s lost in aborts, 1.25s paused (12412x STM_CONTENTION_WRITE_WRITE)
+    File "foo.py", line 10, in f
+      someobj.stuff = 5
+    File "bar.py", line 20, in g
+      someobj.other = 10
+
+This means that 10.5 seconds were lost running transactions that were
+aborted (which caused another 1.25 seconds of lost time by pausing),
+because of the reason shown in the two independent single-entry
+tracebacks: one thread ran the line ``someobj.stuff = 5``, whereas
+another thread concurrently ran the line ``someobj.other = 10`` on the
+same object.  These two writes are done to the same object.  This
+causes a conflict, which aborts one of the two transactions.  In the
+example above this occurred 12412 times.
+
+The two other conflict sources are ``STM_CONTENTION_INEVITABLE``,
+which means that two transactions both tried to do an external
+operation, like printing or reading from a socket or accessing an
+external array of raw data; and ``STM_CONTENTION_WRITE_READ``, which
+means that one transaction wrote to an object but the other one merely
+read it, not wrote to it (in that case only the writing transaction is
+reported; the location for the reads is not recorded because doing so
+is not possible without a very large performance impact).
+
+Common causes of conflicts:
+
+* First of all, any I/O or raw manipulation of memory turns the
+  transaction inevitable ("must not abort").  There can be only one
+  inevitable transaction running at any time.  A common case is if
+  each transaction starts with sending data to a log file.  You should
+  refactor this case so that it occurs either near the end of the
+  transaction (which can then mostly run in non-inevitable mode), or
+  delegate it to a separate transaction or even a separate thread.
+
+* Writing to a list or a dictionary conflicts with any read from the
+  same list or dictionary, even one done with a different key.  For
+  dictionaries and sets, you can try the types ``transaction.stmdict``
+  and ``transaction.stmset``, which behave mostly like ``dict`` and
+  ``set`` but allow concurrent access to different keys.  (What is
+  missing from them so far is lazy iteration: for example,
+  ``stmdict.iterkeys()`` is implemented as ``iter(stmdict.keys())``;
+  and, unlike PyPy's dictionaries and sets, the STM versions are not
+  ordered.)  There are also experimental ``stmiddict`` and
+  ``stmidset`` classes using the identity of the key.
+
+* ``time.time()`` and ``time.clock()`` turn the transaction inevitable
+  in order to guarantee that a call that appears to be later will really
+  return a higher number.  If getting slightly unordered results is
+  fine, use ``transaction.time()`` or ``transaction.clock()``.  The
+  latter operations guarantee to return increasing results only if you
+  can "prove" that two calls occurred in a specific order (for example
+  because they are both called by the same thread).  In cases where no
+  such proof is possible, you might get randomly interleaved values.
+  (If you have two independent transactions, they normally behave as if
+  one of them was fully executed before the other; but using
+  ``transaction.time()`` you might see the "hidden truth" that they are
+  actually interleaved.)
+
+* ``transaction.threadlocalproperty`` can be used at class-level::
+
+      class Foo(object):     # must be a new-style class!
+          x = transaction.threadlocalproperty()
+          y = transaction.threadlocalproperty(dict)
+
+  This declares that instances of ``Foo`` have two attributes ``x``
+  and ``y`` that are thread-local: reading or writing them from
+  concurrently-running transactions will return independent results.
+  (Any other attributes of ``Foo`` instances will be globally visible
+  from all threads, as usual.)  This is useful together with
+  ``TransactionQueue`` for these two cases:
+
+  - For attributes of long-lived objects that change during one
+    transaction, but should always be reset to some initial value
+    around transaction (for example, initialized to 0 at the start of
+    a transaction; or, if used for a list of pending things to do
+    within this transaction, it will always be empty at the end of one
+    transaction).
+
+  - For general caches across transactions.  With ``TransactionQueue``
+    you get a pool of a fixed number N of threads, each running the
+    transactions serially.  A thread-local property will have the
+    value last stored in it by the same thread, which may come from a
+    random previous transaction.  Basically, you get N copies of the
+    property's value, and each transaction accesses a random copy.  It
+    works fine for caches.
+
+  In more details, the optional argument to ``threadlocalproperty()``
+  is the default value factory: in case no value was assigned in the
+  current thread yet, the factory is called and its result becomes the
+  value in that thread (like ``collections.defaultdict``).  If no

+
+* In addition to all of the above, there are cases where write-write
+  conflicts are caused by writing the same value to an attribute again
+  and again.  See for example ea2e519614ab_: this fixes two such
+  issues where we write an object field without first checking if we
+  already did it.  The ``dont_change_any_more`` field is a flag set to
+  ``True`` in that part of the code, but usually this
+  ``rtyper_makekey()`` method will be called many times for the same
+  object; the code used to repeatedly set the flag to ``True``, but
+  now it first checks and only does the write if it is ``False``.
+  Similarly, in the second half of the checkin, the method
+  ``setup_block_entry()`` used to both assign the ``concretetype``
+  fields and return a list, but its two callers were different: one
+  would really need the ``concretetype`` fields initialized, whereas
+  the other would only need to get its result list --- the
+  ``concretetype`` field in that case might already be set or not, but
+  that would not matter.

+Note that Python is a complicated language; there are a number of less
+common cases that may cause conflict (of any kind) where we might not
+expect it at priori.  In many of these cases it could be fixed; please
+report any case that you don't understand.

-Atomic sections, Transactions, etc.: a better way to write parallel programs
-----------------------------------------------------------------------------
+Miscellaneous functions
+-----------------------
 
-(This section is based on locks as we plan to implement them, but also
-works with the existing atomic sections.)
+* First, note that the ``transaction`` module is found in the file
+  ``lib_pypy/transaction.py``.  This file can be copied around to
+  execute the same programs on CPython or on non-STM PyPy, with
+  fall-back behavior.  (One case where the behavior differs is
+  ``atomic``, which is in this fall-back case just a regular lock; so
+  ``with atomic`` only prevent other threads from entering other
+  ``with atomic`` sections, but won't prevent other threads from
+  running non-atomic code.)
 
-In the cases where elision works, the block of code can run in parallel
-with other blocks of code *even if they are protected by the same lock.*
-You still get the illusion that the blocks are run sequentially.  This
-works even for multiple threads that run each a series of such blocks
-and nothing else, protected by one single global lock.  This is
-basically the Python application-level equivalent of what was done with
-the interpreter in ``pypy-stm``: while you think you are writing
-thread-unfriendly code because of this global lock, actually the
-underlying system is able to make it run on multiple cores anyway.
-
-This capability can be hidden in a library or in the framework you use;
-the end user's code does not need to be explicitly aware of using
-threads.  For a simple example of this, there is `transaction.py`_ in
-``lib_pypy``.  The idea is that you write, or already have, some program
-where the function ``f(key, value)`` runs on every item of some big
-dictionary, say::
-
-    for key, value in bigdict.items():
-        f(key, value)
-
-Then you simply replace the loop with::
-
-    for key, value in bigdict.items():
-        transaction.add(f, key, value)
-    transaction.run()
-
-This code runs the various calls to ``f(key, value)`` using a thread
-pool, but every single call is executed under the protection of a unique
-lock.  The end result is that the behavior is exactly equivalent --- in
-fact it makes little sense to do it in this way on a non-STM PyPy or on
-CPython.  But on ``pypy-stm``, the various locked calls to ``f(key,
-value)`` can tentatively be executed in parallel, even if the observable
-result is as if they were executed in some serial order.
-
-This approach hides the notion of threads from the end programmer,
-including all the hard multithreading-related issues.  This is not the
-first alternative approach to explicit threads; for example, OpenMP_ is
-one.  However, it is one of the first ones which does not require the
-code to be organized in a particular fashion.  Instead, it works on any
-Python program which has got latent, imperfect parallelism.  Ideally, it
-only requires that the end programmer identifies where this parallelism
-is likely to be found, and communicates it to the system, using for
-example the ``transaction.add()`` scheme.

   inter-segment overhead, but should be increased in the future.  It
   should also be settable, and the default value should depend on the
   number of actual CPUs.)  If STM is not available, this returns 1.
 
-* ``print_abort_info(minimum_time=0.0)``: debugging help.  Each thread
-  remembers the longest abort or pause it did because of cross-thread
-  contention_.  This function prints it to ``stderr`` if the time lost
-  is greater than ``minimum_time`` seconds.  The record is then
-  cleared, to make it ready for new events.  This function returns

+* ``__pypy__.thread.signals_enabled``: a context manager that runs its

+  threads is useful for libraries where threads are hidden and the end

+  it is called.  This works without generating conflicts.  The
+  returned integers are only roughly in increasing order; this should
+  not be relied upon.
 
-* ``__pypy__.thread.atomic``: a context manager to run a block in
-  fully atomic mode, without "releasing the GIL".  (May be eventually
-  removed?)
 
-* ``__pypy__.thread.signals_enabled``: a context manager that runs its

+// the single (inline) function GetPC.  GetPC is used in a signal
+// handler to figure out the instruction that was being executed when
+// the signal-handler was triggered.
+//
+// To get this, we use the ucontext_t argument to the signal-handler
+// callback, which holds the full context of what was going on when
+// the signal triggered.  How to get from a ucontext_t to a Program
+// Counter is OS-dependent.

+// the single (inline) function GetPC.  GetPC is used in a signal
+// handler to figure out the instruction that was being executed when
+// the signal-handler was triggered.
+//
+// To get this, we use the ucontext_t argument to the signal-handler
+// callback, which holds the full context of what was going on when
+// the signal triggered.  How to get from a ucontext_t to a Program
+// Counter is OS-dependent.

Subject: [pypy-commit] pypy vecopt: test_zjit up and running again (extended
	the fake space)
Message-ID: <20150506142209.9D0571C0F78@cobra.cs.uni-duesseldorf.de>

Author: Richard Plangger <rich at pasra.at>
Branch: vecopt
Changeset: r77158:b2baaa7fb44d
Date: 2015-05-06 10:02 +0200
http://bitbucket.org/pypy/pypy/changeset/b2baaa7fb44d/

Log:	test_zjit up and running again (extended the fake space) enabled
	vectorization algorithm for test_zjit relaxing a guard does now copy
	it' operation (if vecopt fails it does not leave dirty state behind)

+This code has been developed on Linux, but should work on any POSIX
+platform as well as on Windows 32 and 64.  (It relies occasionally on
+libffi, so it depends on libffi being bug-free; this may not be fully
+the case on some of the more exotic platforms.)
 
-It supports CPython 2.6; 2.7; 3.x (tested with 3.2 and 3.3);
-and is distributed with PyPy 2.0 beta2 or later.
+CFFI supports CPython 2.6, 2.7, 3.x (tested with 3.2 to 3.4); and is
+distributed with PyPy 2.0 beta2 or later.  CFFI 1.0 is distributed
+with (and requires) PyPy 2.6.
 
-Its speed is comparable to ctypes on CPython (a bit faster but a higher
-warm-up time).  It is already faster than ctypes on PyPy (1.5x-2x), but not yet
-*much* faster; stay tuned.
+The core speed of CFFI is better than ctypes, with import times being
+either lower if you use the post-1.0 features, or much higher if you
+don't.  The wrapper Python code you typically need to write around the
+raw CFFI interface slows things down on CPython, but not unreasonably
+so.  On PyPy, this wrapper code has a minimal impact thanks to the JIT
+compiler.  This makes CFFI the recommended way to interface with C
+libraries on PyPy.
 
 Requirements:
 
-* CPython 2.6 or 2.7 or 3.x, or PyPy 2.0 beta2
+* CPython 2.6 or 2.7 or 3.x, or PyPy (PyPy 2.0 for the earliest
+  versions of CFFI; or PyPy 2.6 for CFFI 1.0).
 
-* on CPython you need to build the C extension module, so you need
-  ``python-dev`` and ``libffi-dev`` (for Windows, libffi is included
-  with CFFI).
+* in some cases you need to be able to compile C extension modules;
+  refer to the appropriate docs for your OS.  This includes installing
+  CFFI from sources (CPython only, as it is already included with
+  PyPy); or developing code based on ``ffi.set_source()`` or
+  ``ffi.verify()``; or installing such 3rd-party modules from sources.
 
-* pycparser >= 2.06: https://github.com/eliben/pycparser
+* on CPython, on non-Windows platforms, you also need to install
+  ``libffi-dev`` in order to compile CFFI itself.
 
-* a C compiler is required to use CFFI during development, but not to run
-  correctly-installed programs that use CFFI.
+* pycparser >= 2.06: https://github.com/eliben/pycparser (automatically
+  tracked by ``pip install cffi``).
 
-* `py.test`_ is needed to run the tests of CFFI.

Log:	added some missing vector x86 instructions to mc started to
	implement the new instructions (pack/unpack/expand/...) not yet
	finished. i need to find the suitable instructions for those

+Global variable::

+  _cffi_opcode_t _cffi_types[];
+
+Every _cffi_types entry is initially an odd integer.  At runtime, it
+is fixed to be a `CTypeDescrObject *` when the odd integer is
+interpreted and turned into a real <ctype> object.
+
+The generated C functions are listed in _cffi_globals, a sorted array
+of entries which get turned lazily into real <builtin function
+objects>.  Each entry in this array has an index in the _cffi_types
+array, which describe the function type (OP_FUNCTION opcode, see
+below).  We turn the odd integers describing argument and return types
+into real CTypeDescrObjects at the point where the entry is turned
+into a real builtin function object.
+
+The odd integers are "opcodes" that contain a type info in the lowest
+byte.  The remaining high bytes of the integer is an "arg" that depends
+on the type info:
+
+OP_PRIMITIVE
+    the arg tells which primitive type it is (an index in some list)
+
+OP_POINTER
+    the arg is the index of the item type in the _cffi_types array.

+
+OP_NOOP
+    simple indirection: the arg is the index to look further in
+
+There are other opcodes, used not inside _cffi_types but in other
+individual ``type_op`` fields.  Most importantly, these are used
+on _cffi_globals entries:
+
+OP_CPYTHON_BLTN_*
+    declare a function
+
+OP_CONSTANT
+    declare a non-integral constant
+
+OP_CONSTANT_INT
+    declare an int constant
+
+OP_GLOBAL_VAR
+    declare a global var

Log:	added integer/float types to zjit test (int 8,16,32,64, float 32,64)
	extended test_add to use different types than int64/float64 added
	vector cast operation (float -> single float) added IR test case to
	check if type size differences are handled correctly (when
	shrinking) extended the transformation of a pack to a vector
	operation. if an operation (like casting) shrinks the size of vector
	elements, pack instructions copy them in place

Subject: [pypy-commit] pypy vecopt: added many opcodes for x86 that operate
 on packed data (single float)

http://bitbucket.org/pypy/pypy/changeset/9a5fe21d3676/

Log:	added many opcodes for x86 that operate on packed data (single
	float) added a test to stress castup/cast down extended the array
	descriptor with a field that tracks if it loads from a float32
	(necessary for vectorization) there might be another solution for
	that, but this needs to be discussed

-As you can see, we successfully managed to call Python from C and C from
-Python. Now having one callback might not be enough, so what typically happens
-is that we would pass a struct full of callbacks to ``pypy_execute_source_ptr``
-and fill the structure from Python side for the future use.
+As you can see, what we did is create a ``struct API`` that contains
+the custom API that we need in our particular case.  This struct is
+filled by Python to contain a function pointer that is then called
+form the C side.  It is also possible to do have other function
+pointers that are filled by the C side and called by the Python side,
+or even non-function-pointer fields: basically, the two sides
+communicate via this single C structure that defines your API.
 
-Alternative example
--------------------
-
-As ``pypy_execute_source_ptr`` is not available in PyPy 2.2.1, you might want to try 
-an alternative approach which relies on -export-dynamic flag to the GNU linker. 
-The downside to this approach is that it is platform dependent.

-    char source[] = "from cffi import FFI\n\
-    ffi = FFI()\n\
-    @ffi.callback('int(int)')\n\
-    def func(a):\n\
-        print 'Got from C %d' % a\n\
-        return a * 2\n\
-    ffi.cdef('int callback(int (*func)(int));')\n\
-    lib = ffi.verify('int callback(int (*func)(int));')\n\
-    lib.callback(func)\n\
-    print 'finished the Python part'\n\
-    ";
-
-    int callback(int (*func)(int))
-    {
-        printf("Calling to Python, result: %d\n", func(3));
-    }
-
-    int main()
-    {
-        int res;
-        void *lib, *func;
-
-        rpython_startup_code();
-        res = pypy_setup_home("/opt/pypy/bin/libpypy-c.so", 1);
-        if (res) {
-            printf("Error setting pypy home!\n");

-            printf("Error calling pypy_execute_source!\n");
-        }
-        return res;
-    }
-
-
-Make sure to pass -export-dynamic flag when compiling::
-
-   $ gcc -g -o x x.c -lpypy-c -L. -export-dynamic
-   $ LD_LIBRARY_PATH=. ./x
-   Got from C 3

+clauses executed immediately:
 
-* For the same reason, some functions and attributes of the ``gc`` module
-  behave in a slightly different way: for example, ``gc.enable`` and
-  ``gc.disable`` are supported, but instead of enabling and disabling the GC,
-  they just enable and disable the execution of finalizers.  Also,
-  ``gc.garbage`` always returns an empty list.
+.. syntax:: python
 
-* You can't add a ``__del__`` method to an existing class; it
-  must be present in the class since the beginning, or else it
-  will not be automatically called when instances are freed.
+    def mygen():
+        with foo:
+            yield 42
 
-* You can't store non-string keys in type objects. Example
+    for x in mygen():
+        if x == 42:
+            break    # foo.__exit__ is not run immediately!
 
-  .. syntax:: python
+    # fixed version:
+    gen = mygen()
+    try:
+        for x in gen:
+            if x == 42:
+                break
+    finally:
+        gen.close()
 
-    class A(object):
-        locals()[42] = 3
+More generally, ``__del__()`` methods are not executed as predictively
+as on CPython: they run "some time later" in PyPy (or not at all if
+the program finishes running in the meantime).  See `more details
+here`_.
 
-  won't work.

Log:	Issue #2048

	Don't call "divmod(t, 1.0)". This is just a compatibility trick
	with the C version of the datetime module in CPython, which doesn't
	call t.__divmod__() even if it is defined on the class of t.

Log:	Kill 'exchange_result_libffi' and tweak jit_libffi. This might
	actually fix the issue of test_pypy_c/test_ffi failing since a
	random point in time, which I believe is related to a possible
	problem that this checkin fixes.

-As you can see, we successfully managed to call Python from C and C from
-Python. Now having one callback might not be enough, so what typically happens
-is that we would pass a struct full of callbacks to ``pypy_execute_source_ptr``
-and fill the structure from Python side for the future use.
+As you can see, what we did is create a ``struct API`` that contains
+the custom API that we need in our particular case.  This struct is
+filled by Python to contain a function pointer that is then called
+form the C side.  It is also possible to do have other function
+pointers that are filled by the C side and called by the Python side,
+or even non-function-pointer fields: basically, the two sides
+communicate via this single C structure that defines your API.
 
-Alternative example
--------------------
-
-As ``pypy_execute_source_ptr`` is not available in PyPy 2.2.1, you might want to try 
-an alternative approach which relies on -export-dynamic flag to the GNU linker. 
-The downside to this approach is that it is platform dependent.
-
-.. code-block:: c
-
-    #include "include/PyPy.h"

-    char source[] = "from cffi import FFI\n\
-    ffi = FFI()\n\
-    @ffi.callback('int(int)')\n\
-    def func(a):\n\
-        print 'Got from C %d' % a\n\
-        return a * 2\n\
-    ffi.cdef('int callback(int (*func)(int));')\n\
-    lib = ffi.verify('int callback(int (*func)(int));')\n\
-    lib.callback(func)\n\
-    print 'finished the Python part'\n\
-    ";
-
-    int callback(int (*func)(int))
-    {
-        printf("Calling to Python, result: %d\n", func(3));
-    }
-
-    int main()
-    {
-        int res;
-        void *lib, *func;
-
-        rpython_startup_code();
-        res = pypy_setup_home("/opt/pypy/bin/libpypy-c.so", 1);

-            printf("Error calling pypy_execute_source!\n");
-        }
-        return res;
-    }
-
-
-Make sure to pass -export-dynamic flag when compiling::
-
-   $ gcc -g -o x x.c -lpypy-c -L. -export-dynamic
-   $ LD_LIBRARY_PATH=. ./x
-   Got from C 3
-   Calling to Python, result: 6

+======================================
+Preparing and Distributing modules
+======================================
+
+
+The minimal versus the extended FFI class
+-----------------------------------------
+
+CFFI contains actually two different ``FFI`` classes.  The page `Using
+the ffi/lib objects`_ describes the minimal functionality.  One of
+these two classes contains an extended API, described below.
+
+.. _`Using the ffi/lib objects`: using.html
+
+The minimal class is what you get with the out-of-line approach when
+you say ``from _example import ffi``.  The extended class is what you
+get when you say instead::
+
+    import cffi
+
+    ffi = cffi.FFI()
+
+Only the latter kind contains the methods described below, which are
+needed to make FFI objects from scratch or to compile them into
+out-of-line modules.
+
+The reason for this split of functionality is that out-of-line FFI
+objects can be used without loading at all the ``cffi`` package.  In
+fact, a regular program using CFFI out-of-line does not need anything
+from the ``cffi`` pure Python package at all (but still needs
+``_cffi_backend``, a C extension module).
+
+
+Declaring types and functions
+-----------------------------
+
+**ffi.cdef(source)**: parses the given C source.
+It registers all the functions, types, constants and global variables in
+the C source.  The types can be used immediately in ``ffi.new()`` and
+other functions.  Before you can access the functions and global
+variables, you need to give ``ffi`` another piece of information: where
+they actually come from (which you do with either ``ffi.dlopen()`` or
+``ffi.set_source()/ffi.compile()``).
+
+.. _`all types listed above`:
+
+The C source is parsed internally (using ``pycparser``).  This code
+cannot contain ``#include``.  It should typically be a self-contained
+piece of declarations extracted from a man page.  The only things it
+can assume to exist are the standard types:
+
+* char, short, int, long, long long (both signed and unsigned)
+
+* float, double, long double
+
+* intN_t, uintN_t (for N=8,16,32,64), intptr_t, uintptr_t, ptrdiff_t,
+  size_t, ssize_t
+
+* wchar_t (if supported by the backend)
+
+* _Bool and bool (equivalent).  If not directly supported by the C
+  compiler, this is declared with the size of ``unsigned char``.
+
+* FILE.  You can declare C functions taking a ``FILE *`` argument and
+  call them with a Python file object.  If needed, you can also do
+  ``c_f = ffi.cast("FILE *", fileobj)`` and then pass around ``c_f``.
+
+* all `common Windows types`_ are defined if you run
+  on Windows (``DWORD``, ``LPARAM``, etc.).  *Changed in version 0.9:* the
+  types ``TBYTE TCHAR LPCTSTR PCTSTR LPTSTR PTSTR PTBYTE PTCHAR`` are no
+  longer automatically defined; see `ffi.set_unicode()`_.
+
+* *New in version 0.9.3:* the other standard integer types from
+  stdint.h, like ``intmax_t``, as long as they map to integers of 1,
+  2, 4 or 8 bytes.  Larger integers are not supported.
+
+.. _`common Windows types`: http://msdn.microsoft.com/en-us/library/windows/desktop/aa383751%28v=vs.85%29.aspx
+
+.. "versionadded:: 0.9.3": intmax_t etc.
+
+The declarations can also contain "``...``" at various places; these are
+placeholders that will be completed by the compiler.  More information
+about it in the next section.
+
+Note that all standard type names listed above are handled as
+*defaults* only (apart from the ones that are keywords in the C
+language).  If your ``cdef`` contains an explicit typedef that
+redefines one of the types above, then the default described above is
+ignored.  (This is a bit hard to implement cleanly, so in some corner
+cases it might fail, notably with the error ``Multiple type specifiers
+with a type tag``.  Please report it as a bug if it does.)
+
+.. versionadded:: 0.8.2
+   The ``ffi.cdef()`` call takes an optional
+   argument ``packed``: if True, then all structs declared within
+   this cdef are "packed".  If you need both packed and non-packed
+   structs, use several cdefs in sequence.)  This
+   has a meaning similar to ``__attribute__((packed))`` in GCC.  It
+   specifies that all structure fields should have an alignment of one
+   byte.  (Note that the packed attribute has no effect on bit fields so
+   far, which mean that they may be packed differently than on GCC.
+   Also, this has no effect on structs declared with ``"...;"``---next
+   section.)
+
+
+Letting the C compiler fill the gaps
+------------------------------------
+
+If you are using a C compiler (see `API-level`_), then:
+
+*  functions taking or returning integer or float-point arguments can be
+   misdeclared: if e.g. a function is declared by ``cdef()`` as taking a
+   ``int``, but actually takes a ``long``, then the C compiler handles the
+   difference.
+
+*  other arguments are checked: you get a compilation warning or error
+   if you pass a ``int *`` argument to a function expecting a ``long *``.
+
+*  similarly, most things declared in the ``cdef()`` are checked, to
+   the best we implemented so far; mistakes give compilation warnings
+   or errors.
+
+Moreover, you can use "``...``" (literally, dot-dot-dot) in the
+``cdef()`` at various places, in order to ask the C compiler to fill
+in the details.  These places are:
+
+*  structure declarations: any ``struct { }`` that ends with "``...;``" as
+   the last "field" is
+   partial: it may be missing fields and/or have them declared out of order.
+   This declaration will be corrected by the compiler.  (But note that you
+   can only access fields that you declared, not others.)  Any ``struct``
+   declaration which doesn't use "``...``" is assumed to be exact, but this is
+   checked: you get an error if it is not.
+
+*  unknown types: the syntax "``typedef ... foo_t;``" declares the type
+   ``foo_t`` as opaque.  Useful mainly for when the API takes and returns
+   ``foo_t *`` without you needing to look inside the ``foo_t``.  Also
+   works with "``typedef ... *foo_p;``" which declares the pointer type
+   ``foo_p`` without giving a name to the opaque type itself.  Note that
+   such an opaque struct has no known size, which prevents some operations
+   from working (mostly like in C).  *You cannot use this syntax to
+   declare a specific type, like an integer type!  It declares opaque
+   struct-like types only.*  In some cases you need to say that
+   ``foo_t`` is not opaque, but just a struct where you don't know any
+   field; then you would use "``typedef struct { ...; } foo_t;``".
+
+*  array lengths: when used as structure fields or in global variables,
+   arrays can have an unspecified length, as in "``int n[...];``".  The
+   length is completed by the C compiler.  (Only the outermost array
+   may have an unknown length, in case of array-of-array.)
+   This is slightly different from "``int n[];``", because the latter
+   means that the length is not known even to the C compiler.
+
+*  enums: if you don't know the exact order (or values) of the declared
+   constants, then use this syntax: "``enum foo { A, B, C, ... };``"
+   (with a trailing "``...``").  The C compiler will be used to figure
+   out the exact values of the constants.  An alternative syntax is
+   "``enum foo { A=..., B, C };``" or even
+   "``enum foo { A=..., B=..., C=... };``".  Like
+   with structs, an ``enum`` without "``...``" is assumed to
+   be exact, and this is checked.
+
+*  integer constants and macros: you can write in the ``cdef`` the line
+   "``#define FOO ...``", with any macro name FOO but with ``...`` as
+   a value.  Provided the macro
+   is defined to be an integer value, this value will be available via
+   an attribute of the library object.  The
+   same effect can be achieved by writing a declaration
+   ``static const int FOO;``.  The latter is more general because it
+   supports other types than integer types (note: the C syntax is then
+   to write the ``const`` together with the variable name, as in
+   ``static char *const FOO;``).
+
+Currently, it is not supported to find automatically which of the
+various integer or float types you need at which place.  In the case of
+function arguments or return type, when it is a simple integer/float
+type, it may be misdeclared (if you misdeclare a function ``void
+f(long)`` as ``void f(int)``, it still works, but you have to call it
+with arguments that fit an int).  But it doesn't work any longer for
+more complex types (e.g. you cannot misdeclare a ``int *`` argument as
+``long *``) or in other locations (e.g. a global array ``int a[5];``
+must not be misdeclared ``long a[5];``).  CFFI considers `all types listed
+above`_ as primitive (so ``long long a[5];`` and ``int64_t a[5]`` are
+different declarations).
+
+
+Preparing out-of-line modules
+-----------------------------
+
+**ffi.set_source(module_name, c_header_source, [\*\*keywords...])**:
+prepare the ffi for producing out-of-line an external module called
+``module_name``.  *New in version 1.0.*
+
+The final goal is to produce an external module so that ``from
+module_name import ffi`` gives a fast-loading, and possibly
+C-compiler-completed, version of ``ffi``.  This method
+``ffi.set_source()`` is typically called from a separate
+``*_build.py`` file that only contains the logic to build this
+external module.  Note that ``ffi.set_source()`` by itself does not
+write any file, but merely records its arguments for later.  It can be
+called before the ``ffi.cdef()`` or after.  See examples in the
+overview_.
+
+.. _overview: overview.html
+
+The ``module_name`` can be a dotted name, in case you want to generate
+the module inside a package.
+
+The ``c_header_source`` is either some C source code or None.  If it
+is None, the external module produced will be a pure Python module; no
+C compiler is needed, but you cannot use the ``"..."`` syntax in the
+``cdef()``.
+
+On the other hand, if ``c_header_source`` is not None, then you can
+use ``"..."`` in the ``cdef()``.  In this case, you must plan the
+``c_header_source`` to be a string containing C code that will be
+directly pasted in the generated C "source" file, like this::
+
+    ...some internal declarations using the '_cffi_' prefix...
+
+    "c_header_source", pasted directly
+
+    ...some magic code to complete all the "..." from the cdef
+    ...declaration of helper functions and static data structures
+    ...and some standard CPython C extension module code
+
+This makes a CPython C extension module (with a tweak to be
+efficiently compiled on PyPy too).  The ``c_header_source`` should
+contain the ``#include`` and other declarations needed to bring in all
+functions, constants, global variables and types mentioned in the
+``cdef()``.  The "magic code" that follows will complete, check, and
+describe them as static data structures.  When you finally import this
+module, these static data structures will be attached to the ``ffi``
+and ``lib`` objects.
+
+The ``keywords`` arguments are XXXXXXXXX
+
+
+Compiling out-of-line modules
+-----------------------------
+
+Once an FFI object has been prepared, we must really generate the
+.py/.c and possibly compile it.  There are several ways.
+
+**ffi.compile(tmpdir='.'):** explicitly generate the .py/.c and (in
+the second case) compile it.  The output file(s) are in the directory
+given by ``tmpdir``.  This is suitable for
+xxxxxxxxxxxxx
+
+
+
+.. _loading-libraries:
+
+ABI level: Loading libraries
+----------------------------
+
+``ffi.dlopen(libpath, [flags])``: this function opens a shared library and
+returns a module-like library object.  Use this when you are fine with
+the limitations of ABI-level access to the system.  In case of doubt, read
+again `ABI versus API`_ in the overview.
+
+.. _`ABI versus API`: overflow.html#abi-versus-api
+
+You can use the library object to call the functions previously
+declared by ``ffi.cdef()``, to read constants, and to read or write
+global variables.  Note that you can use a single ``cdef()`` to
+declare functions from multiple libraries, as long as you load each of
+them with ``dlopen()`` and access the functions from the correct one.
+
+The ``libpath`` is the file name of the shared library, which can
+contain a full path or not (in which case it is searched in standard
+locations, as described in ``man dlopen``), with extensions or not.
+Alternatively, if ``libpath`` is None, it returns the standard C library
+(which can be used to access the functions of glibc, on Linux).
+
+Let me state it again: this gives ABI-level access to the library, so
+you need to have all types declared manually exactly as they were
+while the library was made.  No checking is done.
+
+Note that only functions and global variables are in library objects;
+types exist in the ``ffi`` instance independently of library objects.
+This is due to the C model: the types you declare in C are not tied to a
+particular library, as long as you ``#include`` their headers; but you
+cannot call functions from a library without linking it in your program,
+as ``dlopen()`` does dynamically in C.
+
+For the optional ``flags`` argument, see ``man dlopen`` (ignored on
+Windows).  It defaults to ``ffi.RTLD_NOW``.
+
+This function returns a "library" object that gets closed when it goes
+out of scope.  Make sure you keep the library object around as long as
+needed.  (Alternatively, the out-of-line FFIs have a method
+``ffi.dlclose()``.)
+
+
+
+**ffi.include(other_ffi)**: includes the typedefs, structs, unions, enums
+and constants defined in another FFI instance.  Usage is similar to a
+``#include`` in C, where a part of the program might include types
+defined in another part for its own usage.  Note that the include()
+method has no effect on functions, constants and global variables, which
+must anyway be accessed directly from the ``lib`` object returned by the
+original FFI instance.  *Note that you should only use one ffi object
+per library; the intended usage of ffi.include() is if you want to
+interface with several inter-dependent libraries.*  For only one
+library, make one ``ffi`` object.  (If the source becomes too large,
+split it up e.g. by collecting the cdef/verify strings from multiple
+Python modules, as long as you call ``ffi.verify()`` only once.)  *New
+in version 0.5.*
+
+.. "versionadded:: 0.5" --- inlined in the previous paragraph
+
+
+
+
+Unimplemented features
+----------------------
+
+All of the ANSI C declarations should be supported, and some of C99.
+Known missing features that are GCC or MSVC extensions:
+
+* Any ``__attribute__`` or ``#pragma pack(n)``
+
+* Additional types: complex numbers, special-size floating and fixed
+  point types, vector types, and so on.  You might be able to access an
+  array of complex numbers by declaring it as an array of ``struct
+  my_complex { double real, imag; }``, but in general you should declare
+  them as ``struct { ...; }`` and cannot access them directly.  This
+  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)
+
+.. _`variable-length array`:
+
+.. versionadded:: 0.8
+   Now supported: variable-length structures, i.e. whose last field is
+   a variable-length array.
+
+Note that since version 0.8, declarations like ``int field[];`` in
+structures are interpreted as variable-length structures.  When used for
+structures that are not, in fact, variable-length, it works too; in this
+case, the difference with using ``int field[...];`` is that, as CFFI
+believes it cannot ask the C compiler for the length of the array, you
+get reduced safety checks: for example, you risk overwriting the
+following fields by passing too many array items in the constructor.
+
+
+Debugging dlopen'ed C libraries
+-------------------------------
+
+A few C libraries are actually hard to use correctly in a ``dlopen()``
+setting.  This is because most C libraries are intented for, and tested
+with, a situation where they are *linked* with another program, using
+either static linking or dynamic linking --- but from a program written
+in C, at start-up, using the linker's capabilities instead of
+``dlopen()``.
+
+This can occasionally create issues.  You would have the same issues in
+another setting than CFFI, like with ``ctypes`` or even plain C code that
+calls ``dlopen()``.  This section contains a few generally useful
+environment variables (on Linux) that can help when debugging these
+issues.
+
+**export LD_TRACE_LOADED_OBJECTS=all**
+
+    provides a lot of information, sometimes too much depending on the
+    setting.  Output verbose debugging information about the dynamic
+    linker. If set to ``all`` prints all debugging information it has, if
+    set to ``help`` prints a help message about which categories can be
+    specified in this environment variable
+
+**export LD_VERBOSE=1**
+
+    (glibc since 2.1) If set to a nonempty string, output symbol
+    versioning information about the program if querying information
+    about the program (i.e., either ``LD_TRACE_LOADED_OBJECTS`` has been set,
+    or ``--list`` or ``--verify`` options have been given to the dynamic
+    linker).
+
+**export LD_WARN=1**
+
+    (ELF only)(glibc since 2.1.3) If set to a nonempty string, warn
+    about unresolved symbols.
+
+
+
+
+
+
+
+**ffi.set_unicode(enabled_flag)**: Windows: if ``enabled_flag`` is
+True, enable the ``UNICODE`` and ``_UNICODE`` defines in C, and
+declare the types ``TBYTE TCHAR LPCTSTR PCTSTR LPTSTR PTSTR PTBYTE
+PTCHAR`` to be (pointers to) ``wchar_t``.  If ``enabled_flag`` is
+False, declare these types to be (pointers to) plain 8-bit characters.
+(These types are not predeclared at all if you don't call
+``set_unicode()``.)  *New in version 0.9.*
+
+The reason behind this method is that a lot of standard functions have
+two versions, like ``MessageBoxA()`` and ``MessageBoxW()``.  The
+official interface is ``MessageBox()`` with arguments like
+``LPTCSTR``.  Depending on whether ``UNICODE`` is defined or not, the
+standard header renames the generic function name to one of the two
+specialized versions, and declares the correct (unicode or not) types.
+
+Usually, the right thing to do is to call this method with True.  Be
+aware (particularly on Python 2) that, afterwards, you need to pass unicode
+strings as arguments instead of not byte strings.  (Before cffi version 0.9,
+``TCHAR`` and friends where hard-coded as unicode, but ``UNICODE`` was,
+inconsistently, not defined by default.)
+
+.. "versionadded:: 0.9" --- inlined in the previous paragraph
+
+
+Reference: verifier
+-------------------
+
+missing
+
+
+
+
+*  ``source``: C code that is pasted verbatim in the generated code (it
+   is *not* parsed internally).  It should contain at least the
+   necessary ``#include``.  It can also contain the complete
+   implementation of some functions declared in ``cdef()``; this is
+   useful if you really need to write a piece of C code, e.g. to access
+   some advanced macros (see the example of ``getyx()`` in
+   `demo/_curses.py`_).
+
+*  ``sources``, ``include_dirs``,
+   ``define_macros``, ``undef_macros``, ``libraries``,
+   ``library_dirs``, ``extra_objects``, ``extra_compile_args``,
+   ``extra_link_args`` (keyword arguments): these are used when
+   compiling the C code, and are passed directly to distutils_.  You
+   typically need at least ``libraries=['foo']`` in order to link with
+   ``libfoo.so`` or ``libfoo.so.X.Y``, or ``foo.dll`` on Windows.  The
+   ``sources`` is a list of extra .c files compiled and linked together.  See
+   the distutils documentation for `more information about the other
+   arguments`__.
+
+.. __: http://docs.python.org/distutils/setupscript.html#library-options
+.. _distutils: http://docs.python.org/distutils/setupscript.html#describing-extension-modules
+.. _`demo/_curses.py`: https://bitbucket.org/cffi/cffi/src/default/demo/_curses.py
+
+.. versionadded:: 0.4
+   The ``tmpdir`` argument to ``verify()`` controls where the C
+   files are created and compiled. Unless the ``CFFI_TMPDIR`` environment
+   variable is set, the default is
+   ``directory_containing_the_py_file/__pycache__`` using the
+   directory name of the .py file that contains the actual call to
+   ``ffi.verify()``.  (This is a bit of a hack but is generally
+   consistent with the location of the .pyc files for your library.
+   The name ``__pycache__`` itself comes from Python 3.)
+
+   The ``ext_package`` argument controls in which package the
+   compiled extension module should be looked from.  This is
+   only useful after `distributing modules using CFFI`_.
+
+   The ``tag`` argument gives an extra string inserted in the
+   middle of the extension module's name: ``_cffi_<tag>_<hash>``.
+   Useful to give a bit more context, e.g. when debugging.
+
+.. _`warning about modulename`:
+
+.. versionadded:: 0.5
+   The ``modulename`` argument can be used to force a specific module
+   name, overriding the name ``_cffi_<tag>_<hash>``.  Use with care,
+   e.g. if you are passing variable information to ``verify()`` but
+   still want the module name to be always the same (e.g. absolute
+   paths to local files).  In this case, no hash is computed and if
+   the module name already exists it will be reused without further
+   check.  Be sure to have other means of clearing the ``tmpdir``
+   whenever you change your sources.
+
+.. versionadded:: 0.9
+   You can give C++ source code in ``ffi.verify()``:
+
+::
+
+     ext = ffi.verify(r'''
+         extern "C" {
+             int somefunc(int somearg) { return real_cpp_func(somearg); }
+         }
+     ''', source_extension='.cpp', extra_compile_args=['-std=c++11'])
+
+.. versionadded:: 0.9
+   The optional ``flags`` argument has been added, see ``man dlopen`` (ignored
+   on Windows).  It defaults to ``ffi.RTLD_NOW``.
+
+.. versionadded:: 0.9
+   The optional ``relative_to`` argument is useful if you need to list
+   local files passed to the C compiler:
+
+::
+
+     ext = ffi.verify(..., sources=['foo.c'], relative_to=__file__)
+
+The line above is roughly the same as::
+
+     ext = ffi.verify(..., sources=['/path/to/this/file/foo.c'])
+
+except that the default name of the produced library is built from the
+CRC checkum of the argument ``sources``, as well as most other arguments
+you give to ``ffi.verify()`` -- but not ``relative_to``.  So if you used
+the second line, it would stop finding the already-compiled library
+after your project is installed, because the ``'/path/to/this/file'``
+suddenly changed.  The first line does not have this problem.
+
+
+
+
+
+
+.. __: `Declaring types and functions`_
+
+Note the following hack to find explicitly the size of any type, in
+bytes::
+
+    ffi.cdef("const int mysize;")
+    lib = ffi.verify("const int mysize = sizeof(THE_TYPE);")
+    print lib.mysize
+
+Note that this approach is meant to call C libraries that are *not* using
+``#include <Python.h>``.  The C functions are called without the GIL,
+and afterwards we don't check if they set a Python exception, for
+example.  You may work around it, but mixing CFFI with ``Python.h`` is
+not recommended.

-Installation and Status
-=======================================================
+.. __: overview.html
 
-Quick installation (for cpython, cffi is distributed with PyPy):
-
-* ``pip install cffi``
-
-* or get the source code via the `Python Package Index`__.
-
-.. __: http://pypi.python.org/pypi/cffi
-
-In more details:
-
-This code has been developed on Linux, but should work on any POSIX
-platform as well as on Windows 32 and 64.  (It relies occasionally on
-libffi, so it depends on libffi being bug-free; this may not be fully
-the case on some of the more exotic platforms.)
-
-CFFI supports CPython 2.6, 2.7, 3.x (tested with 3.2 to 3.4); and is
-distributed with PyPy 2.0 beta2 or later.  CFFI 1.0 is distributed
-with (and requires) PyPy 2.6.
-
-The core speed of CFFI is better than ctypes, with import times being
-either lower if you use the post-1.0 features, or much higher if you
-don't.  The wrapper Python code you typically need to write around the
-raw CFFI interface slows things down on CPython, but not unreasonably
-so.  On PyPy, this wrapper code has a minimal impact thanks to the JIT
-compiler.  This makes CFFI the recommended way to interface with C
-libraries on PyPy.
-
-Requirements:
-
-* CPython 2.6 or 2.7 or 3.x, or PyPy (PyPy 2.0 for the earliest
-  versions of CFFI; or PyPy 2.6 for CFFI 1.0).
-
-* in some cases you need to be able to compile C extension modules;
-  refer to the appropriate docs for your OS.  This includes installing
-  CFFI from sources (CPython only, as it is already included with
-  PyPy); or developing code based on ``ffi.set_source()`` or
-  ``ffi.verify()``; or installing such 3rd-party modules from sources.
-
-* on CPython, on non-Windows platforms, you also need to install
-  ``libffi-dev`` in order to compile CFFI itself.
-
-* pycparser >= 2.06: https://github.com/eliben/pycparser (automatically
-  tracked by ``pip install cffi``).
-
-* `py.test`_ is needed to run the tests of CFFI itself.
-
-.. _`py.test`: http://pypi.python.org/pypi/pytest
-
-Download and Installation:
-
-* http://pypi.python.org/packages/source/c/cffi/cffi-1.0.0.tar.gz
-
-   - Or grab the most current version by following the instructions below.
-
-   - MD5: ...
-
-   - SHA: ...
-
-* Or get it from the `Bitbucket page`_:
-  ``hg clone https://bitbucket.org/cffi/cffi``
-
-* ``python setup.py install`` or ``python setup_base.py install``
-  (should work out of the box on Linux or Windows; see below for
-  `MacOS X`_ or `Windows 64`_.)
-
-* running the tests: ``py.test c/ _cffi1/ testing/`` (if you didn't
-  install cffi yet, you may need ``python setup_base.py build_ext -f
-  -i``)

-Demos:
-
-* The `demo`_ directory contains a number of small and large demos
-  of using ``cffi``.
-
-* The documentation below might be sketchy on details; for now the
-  ultimate reference is given by the tests, notably
-  `_cffi1/test_verify1.py`_ and `_cffi1/test_new_ffi_1.py`_.

-Platform-specific instructions
-------------------------------
-
-``libffi`` is notoriously messy to install and use --- to the point that
-CPython includes its own copy to avoid relying on external packages.
-CFFI does the same for Windows, but not for other platforms (which should
-have their own working libffi's).
-Modern Linuxes work out of the box thanks to ``pkg-config``.  Here are some
-(user-supplied) instructions for other platforms.
-
-
-MacOS X
-+++++++
-
-**Homebrew** (Thanks David Griffin for this)
-
-1) Install homebrew: http://brew.sh
-
-2) Run the following commands in a terminal
-
-::
-
-    brew install pkg-config libffi
-    PKG_CONFIG_PATH=/usr/local/opt/libffi/lib/pkgconfig pip install cffi
-
-
-Aternatively, **on OS/X 10.6** (Thanks Juraj Sukop for this)
-
-For building libffi you can use the default install path, but then, in
-``setup.py`` you need to change::
-
-    include_dirs = []
-
-to::
-
-    include_dirs = ['/usr/local/lib/libffi-3.0.11/include']
-
-Then running ``python setup.py build`` complains about "fatal error: error writing to -: Broken pipe", which can be fixed by running::
-
-    ARCHFLAGS="-arch i386 -arch x86_64" python setup.py build
-
-as described here_.
-
-.. _here: http://superuser.com/questions/259278/python-2-6-1-pycrypto-2-3-pypi-package-broken-pipe-during-build

-Windows 64
-++++++++++
-
-Win32 works and is tested at least each official release.
-
-Status: Win64 received very basic testing and we applied a few essential
-fixes in cffi 0.7.  Please report any other issue.
-
-Note as usual that this is only about running the 64-bit version of
-Python on the 64-bit OS.  If you're running the 32-bit version (the
-common case apparently), then you're running Win32 as far as we're

-Examples
-=======================================================
-
-
-Simple example (ABI level)
---------------------------
-
-.. code-block:: python
-
-    >>> from cffi import FFI
-    >>> ffi = FFI()
-    >>> ffi.cdef("""
-    ...     int printf(const char *format, ...);   // copy-pasted from the man page
-    ... """)                                  
-    >>> C = ffi.dlopen(None)                     # loads the entire C namespace
-    >>> arg = ffi.new("char[]", "world")         # equivalent to C code: char arg[] = "world";
-    >>> C.printf("hi there, %s!\n", arg)         # call printf
-    hi there, world!
-
-Note that on Python 3 you need to pass byte strings to ``char *``
-arguments.  In the above example it would be ``b"world"`` and ``b"hi
-there, %s!\n"``.  In general it is ``somestring.encode(myencoding)``.
-
-
-Real example (API level)
-------------------------
-
-.. code-block:: python
-
-    from cffi import FFI
-    ffi = FFI()
-    ffi.cdef("""     // some declarations from the man page
-        struct passwd {
-            char *pw_name;
-            ...;
-        };
-        struct passwd *getpwuid(int uid);
-    """)
-    C = ffi.verify("""   // passed to the real C compiler
-    #include <sys/types.h>
-    #include <pwd.h>
-    """, libraries=[])   # or a list of libraries to link with
-    p = C.getpwuid(0)
-    assert ffi.string(p.pw_name) == 'root'    # on Python 3: b'root'
-
-Note that the above example works independently of the exact layout of
-``struct passwd``.  It requires a C compiler the first time you run it,
-unless the module is distributed and installed according to the
-`Distributing modules using CFFI`_ intructions below.  See also the
-note about `Cleaning up the __pycache__ directory`_.
-
-You will find a number of larger examples using ``verify()`` in the
-`demo`_ directory.
-
-Struct/Array Example
---------------------
-
-.. code-block:: python
-
-    from cffi import FFI
-    ffi = FFI()
-    ffi.cdef("""
-        typedef struct {
-            unsigned char r, g, b;
-        } pixel_t;
-    """)
-    image = ffi.new("pixel_t[]", 800*600)
-
-    f = open('data', 'rb')     # binary mode -- important
-    f.readinto(ffi.buffer(image))
-    f.close()
-
-    image[100].r = 255
-    image[100].g = 192
-    image[100].b = 128
-
-    f = open('data', 'wb')
-    f.write(ffi.buffer(image))
-    f.close()
-
-This can be used as a more flexible replacement of the struct_ and
-array_ modules.  You could also call ``ffi.new("pixel_t[600][800]")``
-and get a two-dimensional array.
-
-.. _struct: http://docs.python.org/library/struct.html
-.. _array: http://docs.python.org/library/array.html
-
-
-What actually happened?
------------------------
-
-The CFFI interface operates on the same level as C - you declare types
-and functions using the same syntax as you would define them in C.  This
-means that most of the documentation or examples can be copied straight
-from the man pages.
-
-The declarations can contain types, functions and global variables.  The
-cdef in the above examples are just that - they declared "there is a
-function in the C level with this given signature", or "there is a
-struct type with this shape".
-
-The ``dlopen()`` line loads libraries.  C has multiple namespaces - a
-global one and local ones per library. In this example we load the
-global one (``None`` as argument to ``dlopen()``) which always contains
-the standard C library.  You get as a result a ``<FFILibrary>`` object
-that has as attributes all symbols declared in the ``cdef()`` and coming
-from this library.
-
-The ``verify()`` line in the second example is an alternative: instead
-of doing a ``dlopen``, it generates and compiles a piece of C code.
-When using ``verify()`` you have the advantage that you can use "``...``"
-at various places in the ``cdef()``, and the missing information will
-be completed with the help of the C compiler.  It also does checking,
-to verify that your declarations are correct.  If the C compiler gives
-warnings or errors, they are reported here.
-
-Finally, the ``ffi.new()`` lines allocate C objects.  They are filled
-with zeroes initially, unless the optional second argument is used.
-If specified, this argument gives an "initializer", like you can use
-with C code to initialize global variables.
-
-The actual function calls should be obvious.  It's like C.
-
-=======================================================
-
-Distributing modules using CFFI
-=======================================================
-
-If you use CFFI and ``verify()`` in a project that you plan to
-distribute, other users will install it on machines that may not have a
-C compiler.  Here is how to write a ``setup.py`` script using
-``distutils`` in such a way that the extension modules are listed too.
-This lets normal ``setup.py`` commands compile and package the C
-extension modules too.
-
-Example::
-
-  from setuptools import setup
-  --OR--
-  from distutils.core import setup
-
-  # you must import at least the module(s) that define the ffi's
-  # that you use in your application
-  import yourmodule
-
-  setup(...
-        zip_safe=False,     # with setuptools only
-        ext_modules=[yourmodule.ffi.verifier.get_extension()])
-
-Warning: with ``setuptools``, you have to say ``zip_safe=False``,
-otherwise it might or might not work, depending on which verifier engine
-is used!  (I tried to find either workarounds or proper solutions but
-failed so far.)
-
-.. versionadded:: 0.4
-   If your ``setup.py`` installs a whole package, you can put the extension
-   in it too:
-
-::
-  
-  setup(...
-        zip_safe=False,
-        ext_package='yourpackage',     # but see below!
-        ext_modules=[yourmodule.ffi.verifier.get_extension()])
-
-However in this case you must also give the same ``ext_package``
-argument to the original call to ``ffi.verify()``::
-
-  ffi.verify("...", ext_package='yourpackage')
-
-Usually that's all you need, but see the `Reference: verifier`_ section
-for more details about the ``verifier`` object.
-
-
-Cleaning up the __pycache__ directory
--------------------------------------
-
-During development, every time you change the C sources that you pass to
-``cdef()`` or ``verify()``, then the latter will create a new module
-file name, based on two CRC32 hashes computed from these strings.
-This creates more
-and more files in the ``__pycache__`` directory.  It is recommended that
-you clean it up from time to time.  A nice way to do that is to add, in
-your test suite, a call to ``cffi.verifier.cleanup_tmpdir()``.
-Alternatively, you can just completely remove the ``__pycache__``
-directory.
-
-An alternative cache directory can be given as the ``tmpdir`` argument
-to ``verify()``, via the environment variable ``CFFI_TMPDIR``, or by
-calling ``cffi.verifier.set_tmpdir(path)`` prior to calling
-``verify``.

-Reference
-=======================================================
-
-As a guideline: you have already seen in the above examples all the
-major pieces except maybe ``ffi.cast()``.  The rest of this
-documentation gives a more complete reference.
-
-
-Declaring types and functions
------------------------------
-
-``ffi.cdef(source)`` parses the given C source.  This should be done
-first.  It registers all the functions, types, and global variables in
-the C source.  The types can be used immediately in ``ffi.new()`` and
-other functions.  Before you can access the functions and global
-variables, you need to give ``ffi`` another piece of information: where
-they actually come from (which you do with either ``ffi.dlopen()`` or
-``ffi.verify()``).
-
-The C source is parsed internally (using ``pycparser``).  This code
-cannot contain ``#include``.  It should typically be a self-contained
-piece of declarations extracted from a man page.  The only things it
-can assume to exist are the standard types:
-
-* char, short, int, long, long long (both signed and unsigned)
-
-* float, double, long double
-
-* intN_t, uintN_t (for N=8,16,32,64), intptr_t, uintptr_t, ptrdiff_t,
-  size_t, ssize_t
-
-* wchar_t (if supported by the backend)
-
-* *New in version 0.4:* _Bool.  If not directly supported by the C compiler,
-  this is declared with the size of ``unsigned char``.
-
-* *New in version 0.6:* bool.  In CFFI 0.4 or 0.5, you had to manually say
-  ``typedef _Bool bool;``.  Now such a line is optional.
-
-* *New in version 0.4:* FILE.  You can declare C functions taking a
-  ``FILE *`` argument and call them with a Python file object.  If needed,
-  you can also do ``c_f = ffi.cast("FILE *", fileobj)`` and then pass around
-  ``c_f``.
-
-* *New in version 0.6:* all `common Windows types`_ are defined if you run
-  on Windows (``DWORD``, ``LPARAM``, etc.).  *Changed in version 0.9:* the
-  types ``TBYTE TCHAR LPCTSTR PCTSTR LPTSTR PTSTR PTBYTE PTCHAR`` are no
-  longer automatically defined; see ``ffi.set_unicode()`` below.
-
-* *New in version 0.9.3:* the other standard integer types from stdint.h,
-  as long as they map to integers of 1, 2, 4 or 8 bytes.  Larger integers
-  are not supported.  (Actually added in version 0.9 but this was buggy.)
-
-.. _`common Windows types`: http://msdn.microsoft.com/en-us/library/windows/desktop/aa383751%28v=vs.85%29.aspx
-
-.. "versionadded:: 0.4": _Bool
-.. "versionadded:: 0.6": bool
-.. "versionadded:: 0.4": FILE
-.. "versionadded:: 0.6": Wintypes
-.. "versionadded:: 0.9": intmax_t etc.
-
-As we will see on `the verification step`_ below, the declarations can
-also contain "``...``" at various places; these are placeholders that will
-be completed by a call to ``verify()``.
-
-.. versionadded:: 0.6
-   The standard type names listed above are now handled as *defaults*
-   only (apart from the ones that are keywords in the C language).
-   If your ``cdef`` contains an explicit typedef that redefines one of
-   the types above, then the default described above is ignored.  (This
-   is a bit hard to implement cleanly, so in some corner cases it might
-   fail, notably with the error ``Multiple type specifiers with a type
-   tag``.  Please report it as a bug if it does.)
-
-
-Loading libraries
------------------
-
-``ffi.dlopen(libpath, [flags])``: this function opens a shared library and
-returns a module-like library object.  You need to use *either*
-``ffi.dlopen()`` *or* ``ffi.verify()``, documented below_.
-
-You can use the library object to call the functions previously declared
-by ``ffi.cdef()``, and to read or write global variables.  Note that you
-can use a single ``cdef()`` to declare functions from multiple
-libraries, as long as you load each of them with ``dlopen()`` and access
-the functions from the correct one.
-
-The ``libpath`` is the file name of the shared library, which can
-contain a full path or not (in which case it is searched in standard
-locations, as described in ``man dlopen``), with extensions or not.
-Alternatively, if ``libpath`` is None, it returns the standard C library
-(which can be used to access the functions of glibc, on Linux).
-
-This gives ABI-level access to the library: you need to have all types
-declared manually exactly as they were while the library was made.  No
-checking is done.  For this reason, we recommend to use ``ffi.verify()``
-instead when possible.
-
-Note that only functions and global variables are in library objects;
-types exist in the ``ffi`` instance independently of library objects.
-This is due to the C model: the types you declare in C are not tied to a
-particular library, as long as you ``#include`` their headers; but you
-cannot call functions from a library without linking it in your program,
-as ``dlopen()`` does dynamically in C.
-
-For the optional ``flags`` argument, see ``man dlopen`` (ignored on
-Windows).  It defaults to ``ffi.RTLD_NOW``.
-
-This function returns a "library" object that gets closed when it goes
-out of scope.  Make sure you keep the library object around as long as
-needed.
-
-.. _below:
-
-
-The verification step
----------------------
-
-``ffi.verify(source, tmpdir=.., ext_package=.., modulename=.., flags=.., **kwargs)``:
-verifies that the current ffi signatures
-compile on this machine, and return a dynamic library object.  The
-dynamic library can be used to call functions and access global
-variables declared by a previous ``ffi.cdef()``.  You don't need to use
-``ffi.dlopen()`` in this case.
-
-The returned library is a custom one, compiled just-in-time by the C
-compiler: it gives you C-level API compatibility (including calling
-macros, as long as you declared them as functions in ``ffi.cdef()``).
-This differs from ``ffi.dlopen()``, which requires ABI-level
-compatibility and must be called several times to open several shared
-libraries.
-
-On top of CPython, the new library is actually a CPython C extension
-module.
-
-The arguments to ``ffi.verify()`` are:
-
-*  ``source``: C code that is pasted verbatim in the generated code (it
-   is *not* parsed internally).  It should contain at least the
-   necessary ``#include``.  It can also contain the complete
-   implementation of some functions declared in ``cdef()``; this is
-   useful if you really need to write a piece of C code, e.g. to access
-   some advanced macros (see the example of ``getyx()`` in
-   `demo/_curses.py`_).
-
-*  ``sources``, ``include_dirs``,
-   ``define_macros``, ``undef_macros``, ``libraries``,
-   ``library_dirs``, ``extra_objects``, ``extra_compile_args``,
-   ``extra_link_args`` (keyword arguments): these are used when
-   compiling the C code, and are passed directly to distutils_.  You
-   typically need at least ``libraries=['foo']`` in order to link with
-   ``libfoo.so`` or ``libfoo.so.X.Y``, or ``foo.dll`` on Windows.  The
-   ``sources`` is a list of extra .c files compiled and linked together.  See
-   the distutils documentation for `more information about the other
-   arguments`__.
-

-.. _distutils: http://docs.python.org/distutils/setupscript.html#describing-extension-modules
-.. _`demo/_curses.py`: https://bitbucket.org/cffi/cffi/src/default/demo/_curses.py
-
-On the plus side, this solution gives more "C-like" flexibility:
-
-*  functions taking or returning integer or float-point arguments can be
-   misdeclared: if e.g. a function is declared by ``cdef()`` as taking a
-   ``int``, but actually takes a ``long``, then the C compiler handles the
-   difference.
-
-*  other arguments are checked: you get a compilation warning or error
-   if you pass a ``int *`` argument to a function expecting a ``long *``.
-
-Moreover, you can use "``...``" in the following places in the ``cdef()``
-for leaving details unspecified, which are then completed by the C
-compiler during ``verify()``:
-
-*  structure declarations: any ``struct`` that ends with "``...;``" is
-   partial: it may be missing fields and/or have them declared out of order.
-   This declaration will be corrected by the compiler.  (But note that you
-   can only access fields that you declared, not others.)  Any ``struct``
-   declaration which doesn't use "``...``" is assumed to be exact, but this is
-   checked: you get a ``VerificationError`` if it is not.
-
-*  unknown types: the syntax "``typedef ... foo_t;``" declares the type
-   ``foo_t`` as opaque.  Useful mainly for when the API takes and returns
-   ``foo_t *`` without you needing to look inside the ``foo_t``.  Also
-   works with "``typedef ... *foo_p;``" which declares the pointer type
-   ``foo_p`` without giving a name to the opaque type itself.  Note that
-   such an opaque struct has no known size, which prevents some operations
-   from working (mostly like in C).  *You cannot use this syntax to
-   declare a specific type, like an integer type!  It declares opaque
-   types only.*  In some cases you need to say that
-   ``foo_t`` is not opaque, but you just don't know any field in it; then
-   you would use "``typedef struct { ...; } foo_t;``".
-
-*  array lengths: when used as structure fields or in global variables,
-   arrays can have an unspecified length, as in "``int n[...];``".  The
-   length is completed by the C compiler.  (Only the outermost array
-   may have an unknown length, in case of array-of-array.)
-   You can also use the syntax "``int n[];``".
-
-.. versionchanged:: 0.8
-   "``int n[];``" asks for an array of unknown length whose length must
-   *not* be completed by the C compiler.  See `variable-length array`_
-   below.  If the structure does not contain the syntax ``...`` anywhere,
-   it will be not be considered to have a partial layout to complete by
-   the compiler.
-
-*  enums: if you don't know the exact order (or values) of the declared
-   constants, then use this syntax: "``enum foo { A, B, C, ... };``"
-   (with a trailing "``...``").  The C compiler will be used to figure
-   out the exact values of the constants.  An alternative syntax is
-   "``enum foo { A=..., B, C };``" or even
-   "``enum foo { A=..., B=..., C=... };``".  Like
-   with structs, an ``enum`` without "``...``" is assumed to
-   be exact, and this is checked.
-
-*  integer macros: you can write in the ``cdef`` the line
-   "``#define FOO ...``", with any macro name FOO.  Provided the macro
-   is defined to be an integer value, this value will be available via
-   an attribute of the library object returned by ``verify()``.  The
-   same effect can be achieved by writing a declaration
-   ``static const int FOO;``.  The latter is more general because it
-   supports other types than integer types (note: the syntax is then
-   to write the ``const`` together with the variable name, as in
-   ``static char *const FOO;``).
-
-Currently, it is not supported to find automatically which of the
-various integer or float types you need at which place.  In the case of
-function arguments or return type, when it is a simple integer/float
-type, it may be misdeclared (if you misdeclare a function ``void
-f(long)`` as ``void f(int)``, it still works, but you have to call it
-with arguments that fit an int).  But it doesn't work any longer for
-more complex types (e.g. you cannot misdeclare a ``int *`` argument as
-``long *``) or in other locations (e.g. a global array ``int a[5];``
-must not be declared ``long a[5];``).  CFFI considers all types listed
-above__ as primitive (so ``long long a[5];`` and ``int64_t a[5]`` are
-different declarations).
-
-.. __: `Declaring types and functions`_
-
-Note the following hack to find explicitly the size of any type, in
-bytes::
-
-    ffi.cdef("const int mysize;")
-    lib = ffi.verify("const int mysize = sizeof(THE_TYPE);")
-    print lib.mysize
-
-Note that ``verify()`` is meant to call C libraries that are *not* using
-``#include <Python.h>``.  The C functions are called without the GIL,
-and afterwards we don't check if they set a Python exception, for
-example.  You may work around it, but mixing CFFI with ``Python.h`` is
-not recommended.
-
-.. versionadded:: 0.4
-   Unions used to crash ``verify()``.  Fixed.
-
-.. versionadded:: 0.4
-   The ``tmpdir`` argument to ``verify()`` controls where the C
-   files are created and compiled. Unless the ``CFFI_TMPDIR`` environment
-   variable is set, the default is
-   ``directory_containing_the_py_file/__pycache__`` using the
-   directory name of the .py file that contains the actual call to
-   ``ffi.verify()``.  (This is a bit of a hack but is generally
-   consistent with the location of the .pyc files for your library.
-   The name ``__pycache__`` itself comes from Python 3.)
-
-   The ``ext_package`` argument controls in which package the
-   compiled extension module should be looked from.  This is
-   only useful after `distributing modules using CFFI`_.
-
-   The ``tag`` argument gives an extra string inserted in the
-   middle of the extension module's name: ``_cffi_<tag>_<hash>``.
-   Useful to give a bit more context, e.g. when debugging.
-
-.. _`warning about modulename`:
-
-.. versionadded:: 0.5
-   The ``modulename`` argument can be used to force a specific module
-   name, overriding the name ``_cffi_<tag>_<hash>``.  Use with care,
-   e.g. if you are passing variable information to ``verify()`` but
-   still want the module name to be always the same (e.g. absolute
-   paths to local files).  In this case, no hash is computed and if
-   the module name already exists it will be reused without further
-   check.  Be sure to have other means of clearing the ``tmpdir``
-   whenever you change your sources.
-
-.. versionadded:: 0.9
-   You can give C++ source code in ``ffi.verify()``:
-
-::
-
-     ext = ffi.verify(r'''
-         extern "C" {
-             int somefunc(int somearg) { return real_cpp_func(somearg); }
-         }
-     ''', source_extension='.cpp', extra_compile_args=['-std=c++11'])
-
-.. versionadded:: 0.9
-   The optional ``flags`` argument has been added, see ``man dlopen`` (ignored
-   on Windows).  It defaults to ``ffi.RTLD_NOW``.
-
-.. versionadded:: 0.9
-   The optional ``relative_to`` argument is useful if you need to list
-   local files passed to the C compiler:
-
-::
-
-     ext = ffi.verify(..., sources=['foo.c'], relative_to=__file__)
-
-The line above is roughly the same as::
-
-     ext = ffi.verify(..., sources=['/path/to/this/file/foo.c'])
-
-except that the default name of the produced library is built from the
-CRC checkum of the argument ``sources``, as well as most other arguments
-you give to ``ffi.verify()`` -- but not ``relative_to``.  So if you used
-the second line, it would stop finding the already-compiled library
-after your project is installed, because the ``'/path/to/this/file'``
-suddenly changed.  The first line does not have this problem.
-
----------------------
-
-This function returns a "library" object that gets closed when it goes
-out of scope.  Make sure you keep the library object around as long as
-needed.
-
-
-Working with pointers, structures and arrays
---------------------------------------------
-
-The C code's integers and floating-point values are mapped to Python's
-regular ``int``, ``long`` and ``float``.  Moreover, the C type ``char``
-corresponds to single-character strings in Python.  (If you want it to
-map to small integers, use either ``signed char`` or ``unsigned char``.)
-
-Similarly, the C type ``wchar_t`` corresponds to single-character
-unicode strings, if supported by the backend.  Note that in some
-situations (a narrow Python build with an underlying 4-bytes wchar_t
-type), a single wchar_t character may correspond to a pair of
-surrogates, which is represented as a unicode string of length 2.  If
-you need to convert such a 2-chars unicode string to an integer,
-``ord(x)`` does not work; use instead ``int(ffi.cast('wchar_t', x))``.
-
-Pointers, structures and arrays are more complex: they don't have an
-obvious Python equivalent.  Thus, they correspond to objects of type
-``cdata``, which are printed for example as
-``<cdata 'struct foo_s *' 0xa3290d8>``.
-
-``ffi.new(ctype, [initializer])``: this function builds and returns a
-new cdata object of the given ``ctype``.  The ctype is usually some
-constant string describing the C type.  It must be a pointer or array
-type.  If it is a pointer, e.g. ``"int *"`` or ``struct foo *``, then
-it allocates the memory for one ``int`` or ``struct foo``.  If it is
-an array, e.g. ``int[10]``, then it allocates the memory for ten
-``int``.  In both cases the returned cdata is of type ``ctype``.
-
-The memory is initially filled with zeros.  An initializer can be given
-too, as described later.
-
-Example::
-
-    >>> ffi.new("char *")
-    <cdata 'char *' owning 1 bytes>
-    >>> ffi.new("int *")
-    <cdata 'int *' owning 4 bytes>
-    >>> ffi.new("int[10]")
-    <cdata 'int[10]' owning 40 bytes>
-
-.. versionchanged:: 0.2
-   Note that this changed from CFFI version 0.1: what used to be
-   ``ffi.new("int")`` is now ``ffi.new("int *")``.
-
-Unlike C, the returned pointer object has *ownership* on the allocated
-memory: when this exact object is garbage-collected, then the memory is
-freed.  If, at the level of C, you store a pointer to the memory
-somewhere else, then make sure you also keep the object alive for as
-long as needed.  (This also applies if you immediately cast the returned
-pointer to a pointer of a different type: only the original object has
-ownership, so you must keep it alive.  As soon as you forget it, then
-the casted pointer will point to garbage!  In other words, the ownership
-rules are attached to the *wrapper* cdata objects: they are not, and
-cannot, be attached to the underlying raw memory.)  Example::
-
-    global_weakkeydict = weakref.WeakKeyDictionary()
-
-    s1   = ffi.new("struct foo *")
-    fld1 = ffi.new("struct bar *")
-    fld2 = ffi.new("struct bar *")
-    s1.thefield1 = fld1
-    s1.thefield2 = fld2
-    # here the 'fld1' and 'fld2' object must not go away,
-    # otherwise 's1.thefield1/2' will point to garbage!
-    global_weakkeydict[s1] = (fld1, fld2)
-    # now 's1' keeps alive 'fld1' and 'fld2'.  When 's1' goes
-    # away, then the weak dictionary entry will be removed.
-
-The cdata objects support mostly the same operations as in C: you can
-read or write from pointers, arrays and structures.  Dereferencing a
-pointer is done usually in C with the syntax ``*p``, which is not valid
-Python, so instead you have to use the alternative syntax ``p[0]``
-(which is also valid C).  Additionally, the ``p.x`` and ``p->x``
-syntaxes in C both become ``p.x`` in Python.
-
-.. versionchanged:: 0.2
-   You will find ``ffi.NULL`` to use in the same places as the C ``NULL``.
-   Like the latter, it is actually defined to be ``ffi.cast("void *", 0)``.
-   In version 0.1, reading a NULL pointer used to return None;
-   now it returns a regular ``<cdata 'type *' NULL>``, which you can
-   check for e.g. by comparing it with ``ffi.NULL``.
-
-There is no general equivalent to the ``&`` operator in C (because it
-would not fit nicely in the model, and it does not seem to be needed
-here).  But see ``ffi.addressof()`` below__.
-
-__ `Misc methods on ffi`_
-
-Any operation that would in C return a pointer or array or struct type
-gives you a fresh cdata object.  Unlike the "original" one, these fresh
-cdata objects don't have ownership: they are merely references to
-existing memory.
-
-As an exception to the above rule, dereferencing a pointer that owns a
-*struct* or *union* object returns a cdata struct or union object
-that "co-owns" the same memory.  Thus in this case there are two
-objects that can keep the same memory alive.  This is done for cases where
-you really want to have a struct object but don't have any convenient
-place to keep alive the original pointer object (returned by
-``ffi.new()``).
-
-Example::
-
-    ffi.cdef("void somefunction(int *);")
-    lib = ffi.verify("#include <foo.h>")
-
-    x = ffi.new("int *")      # allocate one int, and return a pointer to it
-    x[0] = 42                 # fill it
-    lib.somefunction(x)       # call the C function
-    print x[0]                # read the possibly-changed value
-
-The equivalent of C casts are provided with ``ffi.cast("type", value)``.
-They should work in the same cases as they do in C.  Additionally, this
-is the only way to get cdata objects of integer or floating-point type::
-
-    >>> x = ffi.cast("int", 42)
-    >>> x
-    <cdata 'int' 42>
-    >>> int(x)
-    42
-
-To cast a pointer to an int, cast it to ``intptr_t`` or ``uintptr_t``,
-which are defined by C to be large enough integer types (example on 32
-bits)::
-
-    >>> int(ffi.cast("intptr_t", pointer_cdata))    # signed
-    -1340782304
-    >>> int(ffi.cast("uintptr_t", pointer_cdata))   # unsigned
-    2954184992L
-
-The initializer given as the optional second argument to ``ffi.new()``
-can be mostly anything that you would use as an initializer for C code,
-with lists or tuples instead of using the C syntax ``{ .., .., .. }``.
-Example::
-
-    typedef struct { int x, y; } foo_t;
-
-    foo_t v = { 1, 2 };            // C syntax
-    v = ffi.new("foo_t *", [1, 2]) # CFFI equivalent
-
-    foo_t v = { .y=1, .x=2 };                // C99 syntax
-    v = ffi.new("foo_t *", {'y': 1, 'x': 2}) # CFFI equivalent
-
-Like C, arrays of chars can also be initialized from a string, in
-which case a terminating null character is appended implicitly::
-
-    >>> x = ffi.new("char[]", "hello")
-    >>> x
-    <cdata 'char[]' owning 6 bytes>
-    >>> len(x)        # the actual size of the array
-    6
-    >>> x[5]          # the last item in the array
-    '\x00'
-    >>> x[0] = 'H'    # change the first item
-    >>> ffi.string(x) # interpret 'x' as a regular null-terminated string
-    'Hello'
-
-Similarly, arrays of wchar_t can be initialized from a unicode string,
-and calling ``ffi.string()`` on the cdata object returns the current unicode
-string stored in the wchar_t array (encoding and decoding surrogates as
-needed if necessary).
-
-Note that unlike Python lists or tuples, but like C, you *cannot* index in
-a C array from the end using negative numbers.
-
-More generally, the C array types can have their length unspecified in C
-types, as long as their length can be derived from the initializer, like
-in C::
-
-    int array[] = { 1, 2, 3, 4 };           // C syntax
-    array = ffi.new("int[]", [1, 2, 3, 4])  # CFFI equivalent
-
-As an extension, the initializer can also be just a number, giving
-the length (in case you just want zero-initialization)::
-
-    int array[1000];                  // C syntax
-    array = ffi.new("int[1000]")      # CFFI 1st equivalent
-    array = ffi.new("int[]", 1000)    # CFFI 2nd equivalent
-
-This is useful if the length is not actually a constant, to avoid things
-like ``ffi.new("int[%d]" % x)``.  Indeed, this is not recommended:
-``ffi`` normally caches the string ``"int[]"`` to not need to re-parse
-it all the time.
-
-.. versionadded:: 0.8.2
-   The ``ffi.cdef()`` call takes an optional argument ``packed``: if
-   True, then all structs declared within this cdef are "packed".
-   (If you need both packed and non-packed structs,
-   use several cdefs in sequence.)  This
-   has a meaning similar to ``__attribute__((packed))`` in GCC.  It
-   specifies that all structure fields should have an alignment of one
-   byte.  (Note that the packed attribute has no effect on bit fields so
-   far, which mean that they may be packed differently than on GCC.)
-
-
-Python 3 support
-----------------
-
-Python 3 is supported, but the main point to note is that the ``char`` C
-type corresponds to the ``bytes`` Python type, and not ``str``.  It is
-your responsibility to encode/decode all Python strings to bytes when
-passing them to or receiving them from CFFI.
-
-This only concerns the ``char`` type and derivative types; other parts
-of the API that accept strings in Python 2 continue to accept strings in
-Python 3.
-
-
-An example of calling a main-like thing
----------------------------------------
-
-Imagine we have something like this:
-
-.. code-block:: python
-
-   from cffi import FFI
-   ffi = FFI()
-   ffi.cdef("""
-      int main_like(int argv, char *argv[]);
-   """)
-   lib = ffi.dlopen("some_library.so")
-
-Now, everything is simple, except, how do we create the ``char**`` argument
-here?
-The first idea:
-
-.. code-block:: python
-
-   lib.main_like(2, ["arg0", "arg1"])
-
-does not work, because the initializer receives two Python ``str`` objects
-where it was expecting ``<cdata 'char *'>`` objects.  You need to use
-``ffi.new()`` explicitly to make these objects:
-
-.. code-block:: python
-
-   lib.main_like(2, [ffi.new("char[]", "arg0"),
-                     ffi.new("char[]", "arg1")])
-
-Note that the two ``<cdata 'char[]'>`` objects are kept alive for the
-duration of the call: they are only freed when the list itself is freed,
-and the list is only freed when the call returns.
-
-If you want instead to build an "argv" variable that you want to reuse,
-then more care is needed:
-
-.. code-block:: python
-
-   # DOES NOT WORK!
-   argv = ffi.new("char *[]", [ffi.new("char[]", "arg0"),
-                               ffi.new("char[]", "arg1")])
-
-In the above example, the inner "arg0" string is deallocated as soon
-as "argv" is built.  You have to make sure that you keep a reference
-to the inner "char[]" objects, either directly or by keeping the list
-alive like this:
-
-.. code-block:: python
-
-   argv_keepalive = [ffi.new("char[]", "arg0"),
-                     ffi.new("char[]", "arg1")]
-   argv = ffi.new("char *[]", argv_keepalive)
-
-
-.. versionchanged:: 0.3
-   In older versions, passing a list as the ``char *[]`` argument did
-   not work; you needed to make an ``argv_keepalive`` and an ``argv``
-   in all cases.
-
-
-Function calls
---------------
-
-When calling C functions, passing arguments follows mostly the same
-rules as assigning to structure fields, and the return value follows the
-same rules as reading a structure field.  For example::
-
-    ffi.cdef("""
-        int foo(short a, int b);
-    """)
-    lib = ffi.verify("#include <foo.h>")
-
-    n = lib.foo(2, 3)     # returns a normal integer
-    lib.foo(40000, 3)     # raises OverflowError
-
-As an extension, you can pass to ``char *`` arguments a normal Python
-string (but don't pass a normal Python string to functions that take a
-``char *`` argument and may mutate it!)::
-
-    ffi.cdef("""
-        size_t strlen(const char *);
-    """)
-    C = ffi.dlopen(None)
-
-    assert C.strlen("hello") == 5
-
-You can also pass unicode strings as ``wchar_t *`` arguments.  Note that
-in general, there is no difference between C argument declarations that
-use ``type *`` or ``type[]``.  For example, ``int *`` is fully
-equivalent to ``int[]`` or ``int[5]``.  So you can pass an ``int *`` as
-a list of integers::
-
-    ffi.cdef("""
-        void do_something_with_array(int *array);
-    """)
-    lib.do_something_with_array([1, 2, 3, 4, 5])
-
-CFFI supports passing and returning structs to functions and callbacks.
-Example (sketch)::
-
-    >>> ffi.cdef("""
-    ...     struct foo_s { int a, b; };
-    ...     struct foo_s function_returning_a_struct(void);
-    ... """)
-    >>> lib = ffi.verify("#include <somewhere.h>")
-    >>> lib.function_returning_a_struct()
-    <cdata 'struct foo_s' owning 8 bytes>
-
-There are a few (obscure) limitations to the argument types and return
-type.  You cannot pass directly as argument a union (but a **pointer**
-to a union is fine), nor a struct which uses bitfields (but a
-**pointer** to such a struct is fine).  If you pass a struct (not a
-**pointer** to a struct), the struct type cannot have been declared with
-"``...;``" and completed with ``verify()``; you need to declare it
-completely in ``cdef()``.  You can work around these limitations by
-writing a C function with a simpler signature in the code passed to
-``ffi.verify()``, which calls the real C function.
-
-Aside from these limitations, functions and callbacks can return structs.
-
-CPython only: for performance, ``ffi.verify()`` returns functions as
-objects of type ``<built-in function>``.  They are not ``<cdata>``, so
-you cannot e.g. pass them to some other C function expecting a function
-pointer argument.  Only ``ffi.typeof()`` works on them.  If you really
-need a pointer to the function, use the following workaround::
-  
-    ffi.cdef(""" int (*foo)(int a, int b); """)
-
-i.e. declare them as pointer-to-function in the cdef (even if they are
-regular functions in the C code).
-
-
-Variadic function calls
------------------------
-
-Variadic functions in C (which end with "``...``" as their last
-argument) can be declared and called normally, with the exception that
-all the arguments passed in the variable part *must* be cdata objects.
-This is because it would not be possible to guess, if you wrote this::
-
-    C.printf("hello, %d\n", 42)
-
-that you really meant the 42 to be passed as a C ``int``, and not a
-``long`` or ``long long``.  The same issue occurs with ``float`` versus
-``double``.  So you have to force cdata objects of the C type you want,
-if necessary with ``ffi.cast()``::
-  
-    C.printf("hello, %d\n", ffi.cast("int", 42))
-    C.printf("hello, %ld\n", ffi.cast("long", 42))
-    C.printf("hello, %f\n", ffi.cast("double", 42))
-    C.printf("hello, %s\n", ffi.new("char[]", "world"))
-
-Note that if you are using ``dlopen()``, the function declaration in the
-``cdef()`` must match the original one in C exactly, as usual --- in
-particular, if this function is variadic in C, then its ``cdef()``
-declaration must also be variadic.  You cannot declare it in the
-``cdef()`` with fixed arguments instead, even if you plan to only call
-it with these argument types.  The reason is that some architectures
-have a different calling convention depending on whether the function
-signature is fixed or not.  (On x86-64, the difference can sometimes be
-seen in PyPy's JIT-generated code if some arguments are ``double``.)
-
-Note that the function signature ``int foo();`` is interpreted by CFFI
-as equivalent to ``int foo(void);``.  This differs from the C standard,
-in which ``int foo();`` is really like ``int foo(...);`` and can be
-called with any arguments.  (This feature of C is a pre-C89 relic: the
-arguments cannot be accessed at all in the body of ``foo()`` without
-relying on compiler-specific extensions.)
-
-
-Callbacks
----------
-
-C functions can also be viewed as ``cdata`` objects, and so can be
-passed as callbacks.  To make new C callback objects that will invoke a
-Python function, you need to use::
-
-    >>> def myfunc(x, y):
-    ...    return x + y
-    ...
-    >>> ffi.callback("int(int, int)", myfunc)
-    <cdata 'int(*)(int, int)' calling <function myfunc at 0xf757bbc4>>
-
-.. versionadded:: 0.4
-   Or equivalently as a decorator:
-
-    >>> @ffi.callback("int(int, int)")
-    ... def myfunc(x, y):
-    ...    return x + y
-
-Note that you can also use a C *function pointer* type like ``"int(*)(int,
-int)"`` (as opposed to a C *function* type like ``"int(int, int)"``).  It
-is equivalent here.
-
-Warning: like ffi.new(), ffi.callback() returns a cdata that has
-ownership of its C data.  (In this case, the necessary C data contains
-the libffi data structures to do a callback.)  This means that the
-callback can only be invoked as long as this cdata object is alive.  If
-you store the function pointer into C code, then make sure you also keep this
-object alive for as long as the callback may be invoked.  (If you want
-the callback to remain valid forever, store the object in a fresh global
-variable somewhere.)
-
-Note that callbacks of a variadic function type are not supported.  A
-workaround is to add custom C code.  In the following example, a
-callback gets a first argument that counts how many extra ``int``
-arguments are passed::
-
-    ffi.cdef("""
-        int (*python_callback)(int how_many, int *values);
-        void *const c_callback;   /* pass this ptr to C routines */
-    """)
-    lib = ffi.verify("""
-        #include <stdarg.h>
-        #include <alloca.h>
-        static int (*python_callback)(int how_many, int *values);
-        static int c_callback(int how_many, ...) {
-            va_list ap;
-            /* collect the "..." arguments into the values[] array */
-            int i, *values = alloca(how_many * sizeof(int));
-            va_start(ap, how_many);
-            for (i=0; i<how_many; i++)
-                values[i] = va_arg(ap, int);
-            va_end(ap);
-            return python_callback(how_many, values);
-        }
-    """)
-    lib.python_callback = python_callback
-
-Windows: you can't yet specify the calling convention of callbacks.
-(For regular calls, the correct calling convention should be
-automatically inferred by the C backend.)  Use an indirection, like
-in the example just above.
-
-Be careful when writing the Python callback function: if it returns an
-object of the wrong type, or more generally raises an exception, then
-the exception cannot be propagated.  Instead, it is printed to stderr
-and the C-level callback is made to return a default value.
-
-The returned value in case of errors is 0 or null by default, but can be
-specified with the ``error`` keyword argument to ``ffi.callback()``::
-
-    >>> ffi.callback("int(int, int)", myfunc, error=42)
-
-In all cases the exception is printed to stderr, so this should be
-used only as a last-resort solution.
-
-
-Misc methods on ffi
--------------------
-
-**ffi.include(other_ffi)**: includes the typedefs, structs, unions and
-enum types defined in another FFI instance.  Usage is similar to a
-``#include`` in C, where a part of the program might include types
-defined in another part for its own usage.  Note that the include()
-method has no effect on functions, constants and global variables, which
-must anyway be accessed directly from the ``lib`` object returned by the
-original FFI instance.  *Note that you should only use one ffi object
-per library; the intended usage of ffi.include() is if you want to
-interface with several inter-dependent libraries.*  For only one
-library, make one ``ffi`` object.  (If the source becomes too large,
-split it up e.g. by collecting the cdef/verify strings from multiple
-Python modules, as long as you call ``ffi.verify()`` only once.)  *New
-in version 0.5.*
-
-.. "versionadded:: 0.5" --- inlined in the previous paragraph
-
-**ffi.errno**: the value of ``errno`` received from the most recent C call
-in this thread, and passed to the following C call, is available via
-reads and writes of the property ``ffi.errno``.
-
-**ffi.getwinerror(code=-1)**: on Windows, in addition to ``errno`` we
-also save and restore the ``GetLastError()`` value across function
-calls.  This function returns this error code as a tuple ``(code,
-message)``, adding a readable message like Python does when raising
-WindowsError.  If the argument ``code`` is given, format that code into
-a message instead of using ``GetLastError()``.  *New in version 0.8.*
-(Note that it is also possible to declare and call the ``GetLastError()``
-function as usual.)
-
-.. "versionadded:: 0.8" --- inlined in the previous paragraph
-
-**ffi.string(cdata, [maxlen])**: return a Python string (or unicode
-string) from the 'cdata'.  *New in version 0.3.*
-
-.. "versionadded:: 0.3" --- inlined in the previous paragraph
-
-- If 'cdata' is a pointer or array of characters or bytes, returns the
-  null-terminated string.  The returned string extends until the first
-  null character, or at most 'maxlen' characters.  If 'cdata' is an
-  array then 'maxlen' defaults to its length.  See ``ffi.buffer()`` below
-  for a way to continue past the first null character.  *Python 3:* this
-  returns a ``bytes``, not a ``str``.
-
-- If 'cdata' is a pointer or array of wchar_t, returns a unicode string
-  following the same rules.
-
-- If 'cdata' is a single character or byte or a wchar_t, returns it as a
-  byte string or unicode string.  (Note that in some situation a single
-  wchar_t may require a Python unicode string of length 2.)
-
-- If 'cdata' is an enum, returns the value of the enumerator as a string.
-  If the value is out of range, it is simply returned as the stringified
-  integer.
-
-
-**ffi.buffer(cdata, [size])**: return a buffer object that references
-the raw C data pointed to by the given 'cdata', of 'size' bytes.  The
-'cdata' must be a pointer or an array.  If unspecified, the size of the
-buffer is either the size of what ``cdata`` points to, or the whole size
-of the array.  Getting a buffer is useful because you can read from it
-without an extra copy, or write into it to change the original value;
-you can use for example ``file.write()`` and ``file.readinto()`` with
-such a buffer (for files opened in binary mode).  (Remember that like in
-C, you use ``array + index`` to get the pointer to the index'th item of
-an array.)
-
-.. versionchanged:: 0.4
-   The returned object is not a built-in buffer nor memoryview object,
-   because these objects' API changes too much across Python versions.
-   Instead it has the following Python API (a subset of ``buffer``):
-
-- ``buf[:]`` or ``bytes(buf)``: fetch a copy as a regular byte string (or
-  ``buf[start:end]`` for a part)
-
-- ``buf[:] = newstr``: change the original content (or ``buf[start:end]
-  = newstr``)
-
-- ``len(buf), buf[index], buf[index] = newchar``: access as a sequence
-  of characters.
-
-.. versionchanged:: 0.5
-   The buffer object returned by ``ffi.buffer(cdata)`` keeps alive the
-   ``cdata`` object: if it was originally an owning cdata, then its
-   owned memory will not be freed as long as the buffer is alive.
-   Moreover buffer objects now support weakrefs to them.
-
-.. versionchanged:: 0.8.2
-   Before version 0.8.2, ``bytes(buf)`` was supported in Python 3 to get
-   the content of the buffer, but on Python 2 it would return the repr
-   ``<_cffi_backend.buffer object>``.  This has been fixed.  But you
-   should avoid using ``str(buf)``: it now gives inconsistent results
-   between Python 2 and Python 3 (this is similar to how ``str()``
-   gives inconsistent results on regular byte strings).  Use ``buf[:]``
-   instead.
-
-**ffi.from_buffer(python_buffer)**: return a ``<cdata 'char[]'>`` that
-points to the data of the given Python object, which must support the
-buffer interface.  This is the opposite of ``ffi.buffer()``.  It gives
-a (read-write) reference to the existing data, not a copy; for this
-reason, and for PyPy compatibility, it does not work with the built-in
-types str or unicode or bytearray (or buffers/memoryviews on them).
-It is meant to be used on objects
-containing large quantities of raw data, like ``array.array`` or numpy
-arrays.  It supports both the old buffer API (in Python 2.x) and the
-new memoryview API.  The original object is kept alive (and, in case
-of memoryview, locked) as long as the cdata object returned by
-``ffi.from_buffer()`` is alive.  *New in version 0.9.*
-
-.. "versionadded:: 0.9" --- inlined in the previous paragraph
-
-
-**ffi.typeof("C type" or cdata object)**: return an object of type
-``<ctype>`` corresponding to the parsed string, or to the C type of the
-cdata instance.  Usually you don't need to call this function or to
-explicitly manipulate ``<ctype>`` objects in your code: any place that
-accepts a C type can receive either a string or a pre-parsed ``ctype``
-object (and because of caching of the string, there is no real
-performance difference).  It can still be useful in writing typechecks,
-e.g.::
-  
-    def myfunction(ptr):
-        assert ffi.typeof(ptr) is ffi.typeof("foo_t*")
-        ...
-
-.. versionadded:: 0.4
-   **ffi.CData, ffi.CType**: the Python type of the objects referred to
-   as ``<cdata>`` and ``<ctype>`` in the rest of this document.  Note
-   that some cdata objects may be actually of a subclass of
-   ``ffi.CData``, and similarly with ctype, so you should check with
-   ``if isinstance(x, ffi.CData)``.  Also, ``<ctype>`` objects have
-   a number of attributes for introspection: ``kind`` and ``cname`` are
-   always present, and depending on the kind they may also have
-   ``item``, ``length``, ``fields``, ``args``, ``result``, ``ellipsis``,
-   ``abi``, ``elements`` and ``relements``.
-
-**ffi.sizeof("C type" or cdata object)**: return the size of the
-argument in bytes.  The argument can be either a C type, or a cdata object,
-like in the equivalent ``sizeof`` operator in C.
-
-**ffi.alignof("C type")**: return the alignment of the C type.
-Corresponds to the ``__alignof__`` operator in GCC.
-
-**ffi.offsetof("C struct or array type", *fields_or_indexes)**: return the
-offset within the struct of the given field.  Corresponds to ``offsetof()``
-in C.
-
-.. versionchanged:: 0.9
-   You can give several field names in case of nested structures.  You
-   can also give numeric values which correspond to array items, in case
-   of a pointer or array type.  For example, ``ffi.offsetof("int[5]", 2)``
-   is equal to the size of two integers, as is ``ffi.offsetof("int *", 2)``.
-
-**ffi.getctype("C type" or <ctype>, extra="")**: return the string
-representation of the given C type.  If non-empty, the "extra" string is
-appended (or inserted at the right place in more complicated cases); it
-can be the name of a variable to declare, or an extra part of the type
-like ``"*"`` or ``"[5]"``.  For example
-``ffi.getctype(ffi.typeof(x), "*")`` returns the string representation
-of the C type "pointer to the same type than x"; and
-``ffi.getctype("char[80]", "a") == "char a[80]"``.
-
-**ffi.gc(cdata, destructor)**: return a new cdata object that points to the
-same data.  Later, when this new cdata object is garbage-collected,
-``destructor(old_cdata_object)`` will be called.  Example of usage:
-``ptr = ffi.gc(lib.malloc(42), lib.free)``.  Note that like objects
-returned by ``ffi.new()``, the returned pointer objects have *ownership*,
-which means the destructor is called as soon as *this* exact returned
-object is garbage-collected.  *New in version 0.3* (together
-with the fact that any cdata object can be weakly referenced).
-
-Note that this should be avoided for large memory allocations or
-for limited resources.  This is particularly true on PyPy: its GC does
-not know how much memory or how many resources the returned ``ptr``
-holds.  It will only run its GC when enough memory it knows about has
-been allocated (and thus run the destructor possibly later than you
-would expect).  Moreover, the destructor is called in whatever thread
-PyPy is at that moment, which might be a problem for some C libraries.
-In these cases, consider writing a wrapper class with custom ``__enter__()``
-and ``__exit__()`` methods that allocate and free the C data at known
-points in time, and using it in a ``with`` statement.
-
-.. "versionadded:: 0.3" --- inlined in the previous paragraph
-
-**ffi.new_handle(python_object)**: return a non-NULL cdata of type
-``void *`` that contains an opaque reference to ``python_object``.  You
-can pass it around to C functions or store it into C structures.  Later,
-you can use **ffi.from_handle(p)** to retrive the original
-``python_object`` from a value with the same ``void *`` pointer.
-*Calling ffi.from_handle(p) is invalid and will likely crash if
-the cdata object returned by new_handle() is not kept alive!*
-*New in version 0.7.*
-
-Note that ``from_handle()`` conceptually works like this: it searches in
-the list of cdata objects made by ``new_handle()`` the one which has got
-the same ``void *`` value; and then it fetches in that cdata object the
-corresponding Python object.  The cdata object keeps the Python object
-alive, similar to how ``ffi.new()`` returns a cdata object that keeps a
-piece of memory alive.  If the cdata object *itself* is not alive any
-more, then the association ``void * -> python_object`` is dead and
-``from_handle()`` will crash.
-
-.. "versionadded:: 0.7" --- inlined in the previous paragraph
-
-**ffi.addressof(cdata, *fields_or_indexes)**: equivalent to the C
-expression ``&cdata`` or ``&cdata.field`` or ``&cdata->field`` or
-``&cdata[index]`` (or any combination of fields and indexes).  Works
-with the same ctypes where one of the above expressions would work in
-C, with one exception: if no ``fields_or_indexes`` is specified, it
-cannot be used to take the address of a primitive or pointer (it would
-be difficult to implement because only structs and unions and arrays
-are internally stored as an indirect pointer to the data.  If you need
-a C int whose address can be taken, use ``ffi.new("int[1]")`` in the
-first place; similarly, for a pointer, use ``ffi.new("foo_t *[1]")``.)
-
-The returned pointer is only valid as long as the original ``cdata``
-object is; be sure to keep it alive if it was obtained directly from
-``ffi.new()``.  *New in version 0.4.*
-
-.. versionchanged:: 0.9
-   You can give several field names in case of nested structures, and
-   you can give numeric values for array items.  Note that
-   ``&cdata[index]`` can also be expressed as simply ``cdata + index``,
-   both in C and in CFFI.
-
-.. "versionadded:: 0.4" --- inlined in the previous paragraph
-
-**ffi.set_unicode(enabled_flag)**: Windows: if ``enabled_flag`` is
-True, enable the ``UNICODE`` and ``_UNICODE`` defines in C, and
-declare the types ``TBYTE TCHAR LPCTSTR PCTSTR LPTSTR PTSTR PTBYTE
-PTCHAR`` to be (pointers to) ``wchar_t``.  If ``enabled_flag`` is
-False, declare these types to be (pointers to) plain 8-bit characters.
-(These types are not predeclared at all if you don't call
-``set_unicode()``.)  *New in version 0.9.*
-
-The reason behind this method is that a lot of standard functions have
-two versions, like ``MessageBoxA()`` and ``MessageBoxW()``.  The
-official interface is ``MessageBox()`` with arguments like
-``LPTCSTR``.  Depending on whether ``UNICODE`` is defined or not, the
-standard header renames the generic function name to one of the two
-specialized versions, and declares the correct (unicode or not) types.
-
-Usually, the right thing to do is to call this method with True.  Be
-aware (particularly on Python 2) that you then need to pass unicode
-strings as arguments, not byte strings.  (Before cffi version 0.9,
-``TCHAR`` and friends where hard-coded as unicode, but ``UNICODE`` was,
-inconsistently, not defined by default.)

-
-Unimplemented features
-----------------------
-
-All of the ANSI C declarations should be supported, and some of C99.
-Known missing features that are GCC or MSVC extensions:
-
-* Any ``__attribute__`` or ``#pragma pack(n)``
-
-* Additional types: complex numbers, special-size floating and fixed
-  point types, vector types, and so on.  You might be able to access an
-  array of complex numbers by declaring it as an array of ``struct
-  my_complex { double real, imag; }``, but in general you should declare
-  them as ``struct { ...; }`` and cannot access them directly.  This
-  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)
-
-.. versionadded:: 0.4
-   Now supported: the common GCC extension of anonymous nested
-   structs/unions inside structs/unions.
-
-.. versionadded:: 0.6
-   Enum types follow the GCC rules: they are defined as the first of
-   ``unsigned int``, ``int``, ``unsigned long`` or ``long`` that fits
-   all numeric values.  Note that the first choice is unsigned.  In CFFI
-   0.5 and before, enums were always ``int``.  *Unimplemented: if the enum
-   has very large values in C not declared in CFFI, the enum will incorrectly
-   be considered as an int even though it is really a long!  Work around
-   this by naming the largest value.  A similar but less important problem
-   involves negative values.*
-
-.. _`variable-length array`:
-
-.. versionadded:: 0.8

 you can compile and run it with::

-   fijal at hermann:/opt/pypy$ LD_LIBRARY_PATH=. ./x
-   Got from C 3
-   Calling to Python, result: 6
-   finished the Python part
+    $ gcc -g -o x x.c -lpypy-c -L/opt/pypy/bin -I/opt/pypy/include

-As you can see, we successfully managed to call Python from C and C from
-Python. Now having one callback might not be enough, so what typically happens
-is that we would pass a struct full of callbacks to ``pypy_execute_source_ptr``
-and fill the structure from Python side for the future use.
+As you can see, what we did is create a ``struct API`` that contains
+the custom API that we need in our particular case.  This struct is
+filled by Python to contain a function pointer that is then called
+form the C side.  It is also possible to do have other function
+pointers that are filled by the C side and called by the Python side,
+or even non-function-pointer fields: basically, the two sides
+communicate via this single C structure that defines your API.
 
-Alternative example
--------------------
-
-As ``pypy_execute_source_ptr`` is not available in PyPy 2.2.1, you might want to try 
-an alternative approach which relies on -export-dynamic flag to the GNU linker. 
-The downside to this approach is that it is platform dependent.

-    #include "include/PyPy.h"

-    char source[] = "from cffi import FFI\n\

 Preparing and Distributing modules
 ======================================
 
+There are three or four different ways to use CFFI in a project.
+In order of complexity:
 
-The minimal versus the extended FFI class
------------------------------------------
-
-CFFI contains actually two different ``FFI`` classes.  The page `Using
-the ffi/lib objects`_ describes the minimal functionality.  One of
-these two classes contains an extended API, described below.
-
-.. _`Using the ffi/lib objects`: using.html
-
-The minimal class is what you get with the out-of-line approach when
-you say ``from _example import ffi``.  The extended class is what you
-get when you say instead::
+* The **"in-line", "ABI mode"**::
 
     import cffi
 
     ffi = cffi.FFI()
+    ffi.cdef("C-like declarations")
+    lib = ffi.dlopen("libpath")
 
-Only the latter kind contains the methods described below, which are
-needed to make FFI objects from scratch or to compile them into
-out-of-line modules.
+    # use ffi and lib here
 
-The reason for this split of functionality is that out-of-line FFI
-objects can be used without loading at all the ``cffi`` package.  In
-fact, a regular program using CFFI out-of-line does not need anything
-from the ``cffi`` pure Python package at all (but still needs
-``_cffi_backend``, a C extension module).
+* The **"out-of-line",** but still **"ABI mode",** useful to organize
+  the code and reduce the import time::
 
+    # in a separate file "package/foo_build.py"
+    import cffi
 
-Declaring types and functions
------------------------------
+    ffi = cffi.FFI()
+    ffi.set_source("package._foo", None)
+    ffi.cdef("C-like declarations")
+
+    if __name__ == "__main__":
+        ffi.compile()
+
+  Running ``python foo_build.py`` produces a file ``_foo.py``, which
+  can then be imported in the main program::
+
+    from package._foo import ffi
+    lib = ffi.dlopen("libpath")
+
+    # use ffi and lib here
+
+* The **"out-of-line", "API mode"** gives you the most flexibility to
+  access a C library at the level of C, instead of at the binary
+  level::
+
+    # in a separate file "package/foo_build.py"
+    import cffi
+
+    ffi = cffi.FFI()
+    ffi.set_source("package._foo", "real C code")   # <=
+    ffi.cdef("C-like declarations with '...'")
+
+    if __name__ == "__main__":
+        ffi.compile()
+
+  Running ``python foo_build.py`` produces a file ``_foo.c`` and
+  invokes the C compiler to turn it into a file ``_foo.so`` (or
+  ``_foo.pyd`` or ``_foo.dylib``).  It is a C extension module which
+  can be imported in the main program::
+
+    from package._foo import ffi, lib
+    # no ffi.dlopen()
+
+    # use ffi and lib here
+
+* Finally, you can (but don't have to) use CFFI's **Distutils** or
+  **Setuptools integration** when writing a ``setup.py``.  For
+  Distutils (only in out-of-line API mode)::
+
+    # setup.py (requires CFFI to be installed first)
+    from distutils.core import setup
+
+    import foo_build   # possibly with sys.path tricks to find it
+
+    setup(
+        ...,
+        ext_modules=[foo_build.ffi.distutils_extension()],
+    )
+
+  For Setuptools (out-of-line, but works in ABI or API mode;
+  recommended)::
+
+    # setup.py (with automatic dependency tracking)
+    from setuptools import setup
+
+    setup(
+        ...,
+        setup_requires=["cffi>=1.0.dev0"],
+        cffi_modules=["path/to/foo_build.py:ffi"],
+        install_requires=["cffi>=1.0.dev0"],
+    )
+
+Note that CFFI actually contains two different ``FFI`` classes.  The
+page `Using the ffi/lib objects`_ describes the common functionality.
+This minimum is what you get in the ``from package._foo import ffi``
+lines above.  The extended ``FFI`` class is the one you get from
+``import cffi; ffi = cffi.FFI()``.  It has the same functionality (for
+in-line use), but also the extra methods described below (to prepare
+the FFI).
+
+The reason for this split of functionality is that a regular program
+using CFFI out-of-line does not need to import the ``cffi`` pure
+Python package at all.  (Internally it still needs ``_cffi_backend``,
+a C extension module that comes with CFFI.)

+ffi.dlopen(): loading libraries in ABI mode
+-------------------------------------------
+
+``ffi.dlopen(libpath, [flags])``: this function opens a shared library and
+returns a module-like library object.  Use this when you are fine with
+the limitations of ABI-level access to the system.  In case of doubt, read
+again `ABI versus API`_ in the overview.
+
+.. _`ABI versus API`: overflow.html#abi-versus-api
+
+You can use the library object to call the functions previously
+declared by ``ffi.cdef()``, to read constants, and to read or write
+global variables.  Note that you can use a single ``cdef()`` to
+declare functions from multiple libraries, as long as you load each of
+them with ``dlopen()`` and access the functions from the correct one.
+
+The ``libpath`` is the file name of the shared library, which can
+contain a full path or not (in which case it is searched in standard
+locations, as described in ``man dlopen``), with extensions or not.
+Alternatively, if ``libpath`` is None, it returns the standard C library
+(which can be used to access the functions of glibc, on Linux).
+
+Let me state it again: this gives ABI-level access to the library, so
+you need to have all types declared manually exactly as they were
+while the library was made.  No checking is done.  Mismatches can
+cause random crashes.
+
+Note that only functions and global variables live in library objects;
+the types exist in the ``ffi`` instance independently of library objects.
+This is due to the C model: the types you declare in C are not tied to a
+particular library, as long as you ``#include`` their headers; but you
+cannot call functions from a library without linking it in your program,
+as ``dlopen()`` does dynamically in C.
+
+For the optional ``flags`` argument, see ``man dlopen`` (ignored on
+Windows).  It defaults to ``ffi.RTLD_NOW``.
+
+This function returns a "library" object that gets closed when it goes
+out of scope.  Make sure you keep the library object around as long as
+needed.  (Alternatively, the out-of-line FFIs have a method
+``ffi.dlclose(lib)``.)
+
+
+ffi.set_source(): preparing out-of-line modules
+-----------------------------------------------
+
+**ffi.set_source(module_name, c_header_source, [\*\*keywords...])**:
+prepare the ffi for producing out-of-line an external module called
+``module_name``.  *New in version 1.0.*
+
+``ffi.set_source()`` by itself does not write any file, but merely
+records its arguments for later.  It can therefore be called before or
+after ``ffi.cdef()``.
+
+In **ABI mode,** you call ``ffi.set_source(module_name, None)``.  The
+argument is the name (or dotted name inside a package) of the Python
+module to generate.  In this mode, no C compiler is called.
+
+In **API mode,** the ``c_header_source`` argument is a string that
+will be pasted into the .c file generated.  This piece of C code
+typically contains some ``#include``, but may also contain more,
+like definitions for custom "wrapper" C functions.  The goal is that
+the .c file can be generated like this::
+
+    #include <Python.h>
+
+    ...c_header_source...
+
+    ...magic code...
+
+where the "magic code" is automatically generated from the ``cdef()``.
+For example, if the ``cdef()`` contains ``int foo(int x);`` then the
+magic code will contain logic to call the function ``foo()`` with an
+integer argument, itself wrapped inside some CPython or PyPy-specific
+code.
+
+The keywords arguments to ``set_source()`` control how the C compiler
+will be called.  They are passed directly to distutils_ or setuptools_
+and include at least ``sources``, ``include_dirs``, ``define_macros``,
+``undef_macros``, ``libraries``, ``library_dirs``, ``extra_objects``,
+``extra_compile_args`` and ``extra_link_args``.  You typically need at
+least ``libraries=['foo']`` in order to link with ``libfoo.so`` or
+``libfoo.so.X.Y``, or ``foo.dll`` on Windows.  The ``sources`` is a
+list of extra .c files compiled and linked together (the file
+``module_name.c`` is always generated and automatically added as the
+first argument to ``sources``).  See the distutils documentations for
+`more information about the other arguments`__.
+
+.. __: http://docs.python.org/distutils/setupscript.html#library-options
+.. _distutils: http://docs.python.org/distutils/setupscript.html#describing-extension-modules
+.. _setuptools: https://pythonhosted.org/setuptools/setuptools.html
+
+An extra keyword argument processed internally is
+``source_extension``, defaulting to ``".c"``.  The file generated will
+be actually called ``module_name + source_extension``.  Example for
+C++ (but note that there are a few known issues of C-versus-C++
+compatibility left)::
+
+    ffi.set_source("mymodule", '''
+    extern "C" {
+        int somefunc(int somearg) { return real_cpp_func(somearg); }
+    }

-``ffi.set_source()`` is typically called from a separate
-``*_build.py`` file that only contains the logic to build this
-external module.  Note that ``ffi.set_source()`` by itself does not
-write any file, but merely records its arguments for later.  It can be
-called before the ``ffi.cdef()`` or after.  See examples in the
-overview_.
+**ffi.compile(tmpdir='.'):** explicitly generate the .py or .c file,
+and (in the second case) compile it.  The output file is (or are) put
+in the directory given by ``tmpdir``.
 
-.. _overview: overview.html
+**ffi.emit_python_code(filename):** same as ``ffi.compile()`` in ABI
+mode (i.e. checks that ``ffi.compile()`` would have generated a Python
+file).  The file to write is explicitly named.
 
-The ``module_name`` can be a dotted name, in case you want to generate
-the module inside a package.
+**ffi.emit_c_code(filename):** generate the given .c file.
 
-The ``c_header_source`` is either some C source code or None.  If it
-is None, the external module produced will be a pure Python module; no
-C compiler is needed, but you cannot use the ``"..."`` syntax in the
-``cdef()``.
 
-On the other hand, if ``c_header_source`` is not None, then you can
-use ``"..."`` in the ``cdef()``.  In this case, you must plan the
-``c_header_source`` to be a string containing C code that will be
-directly pasted in the generated C "source" file, like this::
-
-    ...some internal declarations using the '_cffi_' prefix...
-
-    "c_header_source", pasted directly
-
-    ...some magic code to complete all the "..." from the cdef
-    ...declaration of helper functions and static data structures
-    ...and some standard CPython C extension module code
-
-This makes a CPython C extension module (with a tweak to be
-efficiently compiled on PyPy too).  The ``c_header_source`` should
-contain the ``#include`` and other declarations needed to bring in all
-functions, constants, global variables and types mentioned in the
-``cdef()``.  The "magic code" that follows will complete, check, and
-describe them as static data structures.  When you finally import this
-module, these static data structures will be attached to the ``ffi``
-and ``lib`` objects.
-
-The ``keywords`` arguments are XXXXXXXXX
-
-
-Compiling out-of-line modules
------------------------------
-
-Once an FFI object has been prepared, we must really generate the
-.py/.c and possibly compile it.  There are several ways.
-
-**ffi.compile(tmpdir='.'):** explicitly generate the .py/.c and (in
-the second case) compile it.  The output file(s) are in the directory
-given by ``tmpdir``.  This is suitable for
-xxxxxxxxxxxxx
-
-
-
-.. _loading-libraries:
-
-ABI level: Loading libraries
-----------------------------
-
-``ffi.dlopen(libpath, [flags])``: this function opens a shared library and
-returns a module-like library object.  Use this when you are fine with
-the limitations of ABI-level access to the system.  In case of doubt, read
-again `ABI versus API`_ in the overview.
-
-.. _`ABI versus API`: overflow.html#abi-versus-api
-
-You can use the library object to call the functions previously
-declared by ``ffi.cdef()``, to read constants, and to read or write
-global variables.  Note that you can use a single ``cdef()`` to
-declare functions from multiple libraries, as long as you load each of
-them with ``dlopen()`` and access the functions from the correct one.
-
-The ``libpath`` is the file name of the shared library, which can
-contain a full path or not (in which case it is searched in standard
-locations, as described in ``man dlopen``), with extensions or not.
-Alternatively, if ``libpath`` is None, it returns the standard C library
-(which can be used to access the functions of glibc, on Linux).
-
-Let me state it again: this gives ABI-level access to the library, so
-you need to have all types declared manually exactly as they were
-while the library was made.  No checking is done.
-
-Note that only functions and global variables are in library objects;
-types exist in the ``ffi`` instance independently of library objects.
-This is due to the C model: the types you declare in C are not tied to a
-particular library, as long as you ``#include`` their headers; but you
-cannot call functions from a library without linking it in your program,
-as ``dlopen()`` does dynamically in C.
-
-For the optional ``flags`` argument, see ``man dlopen`` (ignored on
-Windows).  It defaults to ``ffi.RTLD_NOW``.
-
-This function returns a "library" object that gets closed when it goes
-out of scope.  Make sure you keep the library object around as long as
-needed.  (Alternatively, the out-of-line FFIs have a method
-``ffi.dlclose()``.)

+Note that if you are using ``dlopen()``, the function declaration in the
+``cdef()`` must match the original one in C exactly, as usual --- in
+particular, if this function is variadic in C, then its ``cdef()``
+declaration must also be variadic.  You cannot declare it in the
+``cdef()`` with fixed arguments instead, even if you plan to only call
+it with these argument types.  The reason is that some architectures
+have a different calling convention depending on whether the function
+signature is fixed or not.  (On x86-64, the difference can sometimes be
+seen in PyPy's JIT-generated code if some arguments are ``double``.)
+
+Note that the function signature ``int foo();`` is interpreted by CFFI
+as equivalent to ``int foo(void);``.  This differs from the C standard,
+in which ``int foo();`` is really like ``int foo(...);`` and can be
+called with any arguments.  (This feature of C is a pre-C89 relic: the
+arguments cannot be accessed at all in the body of ``foo()`` without
+relying on compiler-specific extensions.)

+The reason behind this method is that a lot of standard functions have

+ffi.include(): combining multiple CFFI interfaces
+-------------------------------------------------
 
-**ffi.include(other_ffi)**: includes the typedefs, structs, unions, enums
-and constants defined in another FFI instance.  Usage is similar to a
-``#include`` in C, where a part of the program might include types
-defined in another part for its own usage.  Note that the include()
-method has no effect on functions, constants and global variables, which
-must anyway be accessed directly from the ``lib`` object returned by the
-original FFI instance.  *Note that you should only use one ffi object
-per library; the intended usage of ffi.include() is if you want to
-interface with several inter-dependent libraries.*  For only one
-library, make one ``ffi`` object.  (If the source becomes too large,
-split it up e.g. by collecting the cdef/verify strings from multiple
-Python modules, as long as you call ``ffi.verify()`` only once.)  *New
-in version 0.5.*
+**ffi.include(other_ffi)**: includes the typedefs, structs, unions,
+enums and constants defined in another FFI instance.  This is meant
+for large projects where one CFFI-based interface depends on some
+types or functions declared in a different CFFI-based interface.
 
-.. "versionadded:: 0.5" --- inlined in the previous paragraph
+For out-of-line modules, the ``ffi.include(other_ffi)`` line should
+occur in the build script, and the ``other_ffi`` argument should be
+another FFI that comes from another build script.  When the two build
+scripts are turned into generated files, say ``_ffi.so`` and
+``_other_ffi.so``, then importing ``_ffi.so`` will internally cause
+``_other_ffi.so`` to be imported.
 
+The usage of ``ffi.include()`` is the cdef-level equivalent of a
+``#include`` in C, where a part of the program might include types and
+functions defined in another part for its own usage.  You can see on
+the ``ffi`` object (and associated ``lib`` objects on the *including*
+side) the types and constants declared on the included side.  In API
+mode, you can also see the functions and global variables directly.
+In ABI mode, these must be accessed via the original ``other_lib``
+object returned by the ``dlopen()`` method on ``other_ffi``.
 
+*Note that you should only use one ffi object per library; the
+intended usage of ffi.include() is if you want to interface with
+several inter-dependent libraries.*  For only one library, make one

+ffi.verify(): in-line API-mode
+------------------------------
 
+**ffi.verify()** is supported for backward compatibility, but is
+deprecated.  ``ffi.verify(c_header_source, tmpdir=.., ext_package=..,
+modulename=.., flags=.., **kwargs)`` makes and compiles a C file from
+the ``ffi.cdef()``, like ``ffi.set_source()`` in API mode, and then
+immediately loads and returns the dynamic library object.
 
+The ``c_header_source`` and the extra keyword arguments have the
+same meaning as in ``ffi.set_source()``.
 
+One remaining use case for ``ffi.verify()`` would be the following
+hack to find explicitly the size of any type, in bytes, and have it
+available in Python immediately (e.g. because it is needed in order to
+write the rest of the build script)::
 
+    ffi = cffi.FFI()
+    ffi.cdef("const int mysize;")
+    lib = ffi.verify("const int mysize = sizeof(THE_TYPE);")
+    print lib.mysize
 
-**ffi.set_unicode(enabled_flag)**: Windows: if ``enabled_flag`` is
-True, enable the ``UNICODE`` and ``_UNICODE`` defines in C, and
-declare the types ``TBYTE TCHAR LPCTSTR PCTSTR LPTSTR PTSTR PTBYTE
-PTCHAR`` to be (pointers to) ``wchar_t``.  If ``enabled_flag`` is
-False, declare these types to be (pointers to) plain 8-bit characters.
-(These types are not predeclared at all if you don't call
-``set_unicode()``.)  *New in version 0.9.*
-
-The reason behind this method is that a lot of standard functions have
-two versions, like ``MessageBoxA()`` and ``MessageBoxW()``.  The
-official interface is ``MessageBox()`` with arguments like
-``LPTCSTR``.  Depending on whether ``UNICODE`` is defined or not, the
-standard header renames the generic function name to one of the two
-specialized versions, and declares the correct (unicode or not) types.
-
-Usually, the right thing to do is to call this method with True.  Be

-As you can see, we successfully managed to call Python from C and C from
-Python. Now having one callback might not be enough, so what typically happens
-is that we would pass a struct full of callbacks to ``pypy_execute_source_ptr``
-and fill the structure from Python side for the future use.
+As you can see, what we did is create a ``struct API`` that contains
+the custom API that we need in our particular case.  This struct is
+filled by Python to contain a function pointer that is then called
+form the C side.  It is also possible to do have other function
+pointers that are filled by the C side and called by the Python side,
+or even non-function-pointer fields: basically, the two sides
+communicate via this single C structure that defines your API.
 
-Alternative example
--------------------
-
-As ``pypy_execute_source_ptr`` is not available in PyPy 2.2.1, you might want to try 
-an alternative approach which relies on -export-dynamic flag to the GNU linker. 
-The downside to this approach is that it is platform dependent.

Log:	finished the unpacking for float32/64 and int32/64. added x86 packed
	mul operations (don't know if we ever can use them for int64) typed
	the vector box arguments (including count). they are able to
	automatically unpack/pack instructions if they are not in place
	rewritten most of unpack/pack float (as mentioned earlier) and using
	insertps for float32

Subject: [pypy-commit] pypy vecopt: removed annotation errors that occur
 when building the jit
Message-ID: <20150519145948.1E9CF1C123E@cobra.cs.uni-duesseldorf.de>

Author: Richard Plangger <rich at pasra.at>
Branch: vecopt
Changeset: r77393:18c3705b8f89
Date: 2015-05-19 16:59 +0200
http://bitbucket.org/pypy/pypy/changeset/18c3705b8f89/

Log:	removed annotation errors that occur when building the jit removed
	commented (old) code from assembler do not assign item_size to
	boxvector, but recreate the object instead use getter instead of
	direct access to boxvector (item_size,item_count)

+ *
+ * In order to simplify the encoding process, the original linear magnitude

+ * Each biased linear code has a leading 1 which identifies the segment

+ * of leading 0's. The quantization interval is directly available as the

- *
- * In order to simplify the encoding process, the original linear magnitude

- * (33 - 8191). The result can be seen in the following encoding table:

- * Each biased linear code has a leading 1 which identifies the segment
- * number. The value of the segment number is equal to 7 minus the number
- * of leading 0's. The quantization interval is directly available as the
- * four bits wxyz.  * The trailing bits (a - h) are ignored.
- *
- * Ordinarily the complement of the resulting code word is used for
- * transmission, and so the code word is complemented before it is returned.

Log:	Remove this file: it could be done by running a generic test on top
	of a CPython in which we assume that cffi 1.0 is available, but it's
	not worth it for this file. (There is anyway lib-
	python/2.7/test_pwd.)

+What is PyPy?
+=============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7. It's fast (`pypy and cpython 2.7.x`_ performance comparison)
+due to its integrated tracing JIT compiler.
+
+This release supports **x86** machines on most common operating systems

+as well as newer **ARM** hardware (ARMv6 or ARMv7, with VFPv3) running Linux.

+
+Highlights 
+==========
+
+* The past months have seen pypy mature and grow, as rpython becomes the goto
+  solution for writing fast dynamic language interpreters. Our separation of
+  Rpython and the python interpreter PyPy is now much clearer in the
+  `PyPy documentation`_  and we now have seperate `RPython documentation`_.
+  Tell us what still isn't clear, or even better help us improve the documentation.
+
+* We merged version 2.7.9 of python's stdlib. From the python release notice:
+
+  * The entirety of Python 3.4's `ssl module`_ has been backported. 
+    See `PEP 466`_ for justification.
+
+  * HTTPS certificate validation using the system's certificate store is now
+    enabled by default. See `PEP 476`_ for details.
+
+  * SSLv3 has been disabled by default in httplib and its reverse dependencies
+    due to the `POODLE attack`_.
+
+  * The `ensurepip module`_ has been backported, which provides the pip
+    package manager in every Python 2.7 installation. See `PEP 477`_.
+
+* The garbage collector now ignores parts of the stack which did not change
+  since the last collection, another performance boost
+
+* errno and LastError are saved around cffi calls so things like pdb will not
+  overwrite it
+
+* We continue to asymptotically approach a score of 7 times faster than cpython
+  on our benchmark suite, we now rank 6.98 on latest runs

+
+...and what pypy-stm is not for
+-------------------------------
+
+``pypy-stm`` gives a Python without the GIL.  This means that it is
+useful in situations where the GIL is the problem in the first place.
+(This includes cases where the program can easily be modified to run
+in multiple threads; often, we don't consider doing that precisely
+because of the GIL.)
+
+However, there are plenty of cases where the GIL is not the problem.
+Do not hope ``pypy-stm`` to be helpful in these cases!  This includes
+all programs that use multiple threads but don't actually spend a lot
+of time running Python code.  For example, it may be spending all its
+time waiting for I/O to occur, or performing some long computation on
+a huge matrix.  These are cases where the CPU is either idle, or in
+some C/Fortran library anyway; in both cases, the interpreter (either
+CPython or the regular PyPy) should release the GIL around the
+external calls.  The threads will thus not end up fighting for the
+GIL.

+How to write multithreaded programs: the 10'000-feet view
+---------------------------------------------------------
+
+PyPy-STM offers two ways to write multithreaded programs:
+
+* the traditional way, using the ``thread`` or ``threading`` modules,
+  described first__.
+
+* using ``TransactionQueue``, described next__, as a way to hide the
+  low-level notion of threads.
+
+.. __: `Drop-in replacement`_
+.. __: `transaction.TransactionQueue`_
+
+The issues with low-level threads are well known (particularly in other
+languages that don't have GIL-based interpreters): memory corruption,
+deadlocks, livelocks, and so on.  There are alternative approaches to
+dealing directly with threads, like OpenMP_.  These approaches
+typically enforce some structure on your code.  ``TransactionQueue``
+is in part similar: your program needs to have "some chances" of
+parallelization before you can apply it.  But I believe that the scope
+of applicability is much larger with ``TransactionQueue`` than with
+other approaches.  It usually works without forcing a complete
+reorganization of your existing code, and it works on any Python
+program which has got *latent* and *imperfect* parallelism.  Ideally,
+it only requires that the end programmer identifies where this
+parallelism is likely to be found, and communicates it to the system
+using a simple API.

 can execute in parallel, but will commit in some serial order.  They
 appear to behave as if they were completely run in this serialization
 order.
 
 
+transaction.TransactionQueue
+----------------------------
+
+In CPU-hungry programs, we can often easily identify outermost loops
+over some data structure, or other repetitive algorithm, where each
+"block" consists of processing a non-trivial amount of data, and where
+the blocks "have a good chance" to be independent from each other.  We
+don't need to prove that they are actually independent: it is enough
+if they are *often independent* --- or, more precisely, if we *think
+they should be* often independent.
+
+One typical example would look like this, where the function ``func()``
+typically invokes a large amount of code::
+
+    for key, value in bigdict.items():
+        func(key, value)
+
+Then you simply replace the loop with::
+
+    from transaction import TransactionQueue
+
+    tr = TransactionQueue()
+    for key, value in bigdict.items():
+        tr.add(func, key, value)
+    tr.run()
+
+This code's behavior is equivalent.  Internally, the
+``TransactionQueue`` object will start N threads and try to run the
+``func(key, value)`` calls on all threads in parallel.  But note the
+difference with a regular thread-pooling library, as found in many
+lower-level languages than Python: the function calls are not randomly
+interleaved with each other just because they run in parallel.  The
+behavior did not change because we are using ``TransactionQueue``.
+All the calls still *appear* to execute in some serial order.
+
+A typical usage of ``TransactionQueue`` goes like that: at first,
+the performance does not increase.
+In fact, it is likely to be worse.  Typically, this is
+indicated by the total CPU usage, which remains low (closer to 1 than
+N cores).  First note that it is expected that the CPU usage should
+not go much higher than 1 in the JIT warm-up phase: you must run a
+program for several seconds, or for larger programs at least one
+minute, to give the JIT a chance to warm up enough.  But if CPU usage
+remains low even afterwards, then the ``PYPYSTM`` environment variable
+can be used to track what is going on.
+
+Run your program with ``PYPYSTM=logfile`` to produce a log file called
+``logfile``.  Afterwards, use the ``pypy/stm/print_stm_log.py``
+utility to inspect the content of this log file.  It produces output
+like this (sorted by amount of time lost, largest first)::
+
+    10.5s lost in aborts, 1.25s paused (12412x STM_CONTENTION_WRITE_WRITE)
+    File "foo.py", line 10, in f
+      someobj.stuff = 5
+    File "bar.py", line 20, in g
+      someobj.other = 10
+
+This means that 10.5 seconds were lost running transactions that were
+aborted (which caused another 1.25 seconds of lost time by pausing),
+because of the reason shown in the two independent single-entry
+tracebacks: one thread ran the line ``someobj.stuff = 5``, whereas
+another thread concurrently ran the line ``someobj.other = 10`` on the
+same object.  These two writes are done to the same object.  This
+causes a conflict, which aborts one of the two transactions.  In the
+example above this occurred 12412 times.
+
+The two other conflict sources are ``STM_CONTENTION_INEVITABLE``,
+which means that two transactions both tried to do an external
+operation, like printing or reading from a socket or accessing an
+external array of raw data; and ``STM_CONTENTION_WRITE_READ``, which
+means that one transaction wrote to an object but the other one merely
+read it, not wrote to it (in that case only the writing transaction is
+reported; the location for the reads is not recorded because doing so
+is not possible without a very large performance impact).
+
+Common causes of conflicts:
+
+* First of all, any I/O or raw manipulation of memory turns the
+  transaction inevitable ("must not abort").  There can be only one
+  inevitable transaction running at any time.  A common case is if
+  each transaction starts with sending data to a log file.  You should
+  refactor this case so that it occurs either near the end of the
+  transaction (which can then mostly run in non-inevitable mode), or
+  delegate it to a separate transaction or even a separate thread.
+
+* Writing to a list or a dictionary conflicts with any read from the
+  same list or dictionary, even one done with a different key.  For
+  dictionaries and sets, you can try the types ``transaction.stmdict``
+  and ``transaction.stmset``, which behave mostly like ``dict`` and
+  ``set`` but allow concurrent access to different keys.  (What is
+  missing from them so far is lazy iteration: for example,
+  ``stmdict.iterkeys()`` is implemented as ``iter(stmdict.keys())``;
+  and, unlike PyPy's dictionaries and sets, the STM versions are not
+  ordered.)  There are also experimental ``stmiddict`` and
+  ``stmidset`` classes using the identity of the key.
+
+* ``time.time()`` and ``time.clock()`` turn the transaction inevitable
+  in order to guarantee that a call that appears to be later will really
+  return a higher number.  If getting slightly unordered results is
+  fine, use ``transaction.time()`` or ``transaction.clock()``.  The
+  latter operations guarantee to return increasing results only if you
+  can "prove" that two calls occurred in a specific order (for example
+  because they are both called by the same thread).  In cases where no
+  such proof is possible, you might get randomly interleaved values.
+  (If you have two independent transactions, they normally behave as if
+  one of them was fully executed before the other; but using
+  ``transaction.time()`` you might see the "hidden truth" that they are
+  actually interleaved.)
+
+* ``transaction.threadlocalproperty`` can be used at class-level::
+
+      class Foo(object):     # must be a new-style class!
+          x = transaction.threadlocalproperty()
+          y = transaction.threadlocalproperty(dict)
+
+  This declares that instances of ``Foo`` have two attributes ``x``
+  and ``y`` that are thread-local: reading or writing them from
+  concurrently-running transactions will return independent results.
+  (Any other attributes of ``Foo`` instances will be globally visible
+  from all threads, as usual.)  The optional argument to
+  ``threadlocalproperty()`` is the default value factory: in case no
+  value was assigned in the current thread yet, the factory is called
+  and its result becomes the value in that thread (like
+  ``collections.defaultdict``).  If no default value factory is
+  specified, uninitialized reads raise ``AttributeError``.  Note that
+  with ``TransactionQueue`` you get a pool of a fixed number of
+  threads, each running the transactions one after the other; such
+  thread-local properties will have the value last stored in them in
+  the same thread,, which may come from a random previous transaction.
+  This means that ``threadlocalproperty`` is useful mainly to avoid
+  conflicts from cache-like data structures.
+
+Note that Python is a complicated language; there are a number of less
+common cases that may cause conflict (of any kind) where we might not
+expect it at priori.  In many of these cases it could be fixed; please
+report any case that you don't understand.

-underlying system is able to make it run on multiple cores anyway.
-
-This capability can be hidden in a library or in the framework you use;
-the end user's code does not need to be explicitly aware of using
-threads.  For a simple example of this, there is `transaction.py`_ in
-``lib_pypy``.  The idea is that you write, or already have, some program
-where the function ``f(key, value)`` runs on every item of some big
-dictionary, say::
-
-    for key, value in bigdict.items():
-        f(key, value)
-
-Then you simply replace the loop with::
-
-    for key, value in bigdict.items():
-        transaction.add(f, key, value)
-    transaction.run()
-
-This code runs the various calls to ``f(key, value)`` using a thread
-pool, but every single call is executed under the protection of a unique
-lock.  The end result is that the behavior is exactly equivalent --- in
-fact it makes little sense to do it in this way on a non-STM PyPy or on
-CPython.  But on ``pypy-stm``, the various locked calls to ``f(key,
-value)`` can tentatively be executed in parallel, even if the observable
-result is as if they were executed in some serial order.
-
-This approach hides the notion of threads from the end programmer,
-including all the hard multithreading-related issues.  This is not the
-first alternative approach to explicit threads; for example, OpenMP_ is
-one.  However, it is one of the first ones which does not require the
-code to be organized in a particular fashion.  Instead, it works on any
-Python program which has got latent, imperfect parallelism.  Ideally, it
-only requires that the end programmer identifies where this parallelism
-is likely to be found, and communicates it to the system, using for
-example the ``transaction.add()`` scheme.

-API of transactional_memory
----------------------------
-
-The new pure Python module ``transactional_memory`` runs on both CPython
-and PyPy, both with and without STM.  It contains:
-
-* ``getsegmentlimit()``: return the number of "segments" in
+* ``transaction.getsegmentlimit()``: return the number of "segments" in
   this pypy-stm.  This is the limit above which more threads will not be
   able to execute on more cores.  (Right now it is limited to 4 due to
   inter-segment overhead, but should be increased in the future.  It
   should also be settable, and the default value should depend on the
   number of actual CPUs.)  If STM is not available, this returns 1.
 
-* ``print_abort_info(minimum_time=0.0)``: debugging help.  Each thread
-  remembers the longest abort or pause it did because of cross-thread
-  contention_.  This function prints it to ``stderr`` if the time lost
-  is greater than ``minimum_time`` seconds.  The record is then
-  cleared, to make it ready for new events.  This function returns
-  ``True`` if it printed a report, and ``False`` otherwise.
+* ``__pypy__.thread.signals_enabled``: a context manager that runs its
+  block of code with signals enabled.  By default, signals are only
+  enabled in the main thread; a non-main thread will not receive
+  signals (this is like CPython).  Enabling signals in non-main
+  threads is useful for libraries where threads are hidden and the end
+  user is not expecting his code to run elsewhere than in the main
+  thread.
 
+* ``pypystm.exclusive_atomic``: a context manager similar to
+  ``transaction.atomic`` but which complains if it is nested.
 
-API of __pypy__.thread
-----------------------
+* ``transaction.is_atomic()``: return True if called from an atomic
+  context.
 
-The ``__pypy__.thread`` submodule is a built-in module of PyPy that
-contains a few internal built-in functions used by the
-``transactional_memory`` module, plus the following:
+* ``pypystm.count()``: return a different positive integer every time
+  it is called.  This works without generating conflicts.  The
+  returned integers are only roughly in increasing order; this should
+  not be relied upon.
 
-* ``__pypy__.thread.atomic``: a context manager to run a block in
-  fully atomic mode, without "releasing the GIL".  (May be eventually
-  removed?)
 
-* ``__pypy__.thread.signals_enabled``: a context manager that runs its
-  block with signals enabled.  By default, signals are only enabled in
-  the main thread; a non-main thread will not receive signals (this is
-  like CPython).  Enabling signals in non-main threads is useful for
-  libraries where threads are hidden and the end user is not expecting
-  his code to run elsewhere than in the main thread.

+Packaging (preparing for installation)
+--------------------------------------
+
+Packaging is required if you want to install PyPy system-wide, even to
+install on the same machine.  The reason is that doing so prepares a
+number of extra features that cannot be done lazily on a root-installed
+PyPy, because the normal users don't have write access.  This concerns
+mostly libraries that would normally be compiled if and when they are
+imported the first time.
+
+::
+    
+    cd pypy/tool/release
+    ./package.py pypy-VER-PLATFORM
+
+This creates a clean and prepared hierarchy, as well as a ``.tar.bz2``
+with the same content; both are found by default in
+``/tmp/usession-YOURNAME/build/``.  You can then either move the file
+hierarchy or unpack the ``.tar.bz2`` at the correct place.

 Alternatively, as with regular Python, you can simply give a

+If you want anyway to enable all built-in modules, you can use

 the STM framework within RPython is currently targeting the PyPy
 interpreter and other ones might have slightly different needs.
+But in general, all the tedious transformations are done by RPython

+
+The core of STM works as a library written in C (see `reference to
+implementation details`_ below).  It means that it can be used on
+other interpreters than the ones produced by RPython.  Duhton_ is an
+early example of that.  At this point, you might think about adapting
+this library for CPython.  You're warned, though: as far as I can
+tell, it is a doomed idea.  I had a hard time debugging Duhton, and
+that's infinitely simpler than CPython.  Even ignoring that, you can
+see in the C sources of Duhton that many core design decisions are
+different than in CPython: no refcounting; limited support for
+prebuilt "static" objects; ``stm_read()`` and ``stm_write()`` macro
+calls everywhere (and getting very rare and very obscure bugs if you
+forget one); and so on.  You could imagine some custom special-purpose
+extension of the C language, which you would preprocess to regular C.
+In my opinion that's starting to look a lot like RPython itself, but
+maybe you'd prefer this approach.  Of course you still have to worry
+about each and every C extension module you need, but maybe you'd have

+  from all threads, as usual.)  This is useful together with
+  ``TransactionQueue`` for these two cases:
+
+  - For attributes of long-lived objects that change during one
+    transaction, but should always be reset to some initial value
+    around transaction (for example, initialized to 0 at the start of
+    a transaction; or, if used for a list of pending things to do
+    within this transaction, it will always be empty at the end of one
+    transaction).
+

+    you get a pool of a fixed number N of threads, each running the
+    transactions serially.  A thread-local property will have the
+    value last stored in it by the same thread, which may come from a
+    random previous transaction.  Basically, you get N copies of the
+    property's value, and each transaction accesses a random copy.  It
+    works fine for caches.

+  default value factory is specified, uninitialized reads raise
+  ``AttributeError``.
+
+* In addition to all of the above, there are cases where write-write
+  conflicts are caused by writing the same value to an attribute again
+  and again.  See for example ea2e519614ab_: this fixes two such
+  issues where we write an object field without first checking if we
+  already did it.  The ``dont_change_any_more`` field is a flag set to
+  ``True`` in that part of the code, but usually this
+  ``rtyper_makekey()`` method will be called many times for the same
+  object; the code used to repeatedly set the flag to ``True``, but
+  now it first checks and only does the write if it is ``False``.
+  Similarly, in the second half of the checkin, the method
+  ``setup_block_entry()`` used to both assign the ``concretetype``
+  fields and return a list, but its two callers were different: one
+  would really need the ``concretetype`` fields initialized, whereas
+  the other would only need to get its result list --- the
+  ``concretetype`` field in that case might already be set or not, but

Subject: [pypy-commit] pypy vecopt: rewritten the guard strengthening. it is
 now independent from vecopt (still contained in the same file though).

Log:	rewritten the guard strengthening. it is now independent from vecopt
	(still contained in the same file though). the previous version was
	not correct and could only rewrite int_add. now if a guard implies a
	previous guard, the earlier guard is replaced directly

-branch gc-incminimark-pinning-improve: 
-Object Pinning is now used in `bz2` and `rzlib` (therefore also affects
-Python's `zlib`). In case the data to compress/decompress is inside the nursery
-(incminimark) it no longer needs to create a non-moving copy of it. This saves
-one `malloc` and copying the data.  Additionally a new GC environment variable
-is introduced (`PYPY_GC_MAX_PINNED`) primarily for debugging purposes.

+=========================
+PyPy 2.6.0 - XXXXXXXXXXXX
+=========================
+
+We're pleased to announce PyPy 2.6.0, only two months after PyPy 2.5.1.
+We are particulary happy to update `cffi`_ to version 1.0, which makes the
+popular ctypes-alternative even easier to use.
+
+You can download the PyPy 2.6.0 release here:
+
+    http://pypy.org/download.html
+
+We would like to thank our donors for the continued support of the PyPy
+project, and for those who donate to our three sub-projects, as well as our
+volunteers and contributors.  
+We've shown quite a bit of progress, but we're slowly running out of funds.
+Please consider donating more, or even better convince your employer to donate,
+so we can finish those projects! The three sub-projects are:
+
+* `Py3k`_ (supporting Python 3.x): We have released a Python 3.2.5 compatible version
+   we call PyPy3 2.4.0, and are working toward a Python 3.3 compatible version
+
+* `STM`_ (software transactional memory): We have released a first working version,
+  and continue to try out new promising paths of achieving a fast multithreaded Python
+
+* `NumPy`_ which requires installation of our fork of upstream numpy,
+  available `on bitbucket`_
+
+.. _`cffi`: https://cffi.readthedocs.org
+.. _`Py3k`: http://pypy.org/py3donate.html

+.. _`NumPy`: http://pypy.org/numpydonate.html
+.. _`on bitbucket`: https://www.bitbucket.org/pypy/numpy
+
+We would also like to encourage new people to join the project. PyPy has many
+layers and we need help with all of them: `PyPy`_ and `Rpython`_ documentation
+improvements, tweaking popular `modules`_ to run on pypy, or general `help`_ with making
+Rpython's JIT even better.

+
+What is PyPy?
+=============
+
+PyPy is a very compliant Python interpreter, almost a drop-in replacement for
+CPython 2.7. It's fast (`pypy and cpython 2.7.x`_ performance comparison)
+due to its integrated tracing JIT compiler.
+
+This release supports **x86** machines on most common operating systems
+(Linux 32/64, Mac OS X 64, Windows, and OpenBSD),
+as well as newer **ARM** hardware (ARMv6 or ARMv7, with VFPv3) running Linux.
+
+While we support 32 bit python on Windows, work on the native Windows 64
+bit python is still stalling, we would welcome a volunteer
+to `handle that`_.
+
+.. _`pypy and cpython 2.7.x`: http://speed.pypy.org
+.. _`handle that`: http://doc.pypy.org/en/latest/windows.html#what-is-missing-for-a-full-64-bit-translation
+
+Highlights 
+==========
+
+* Improve support for TLS 1.1 and 1.2
+
+* Improved object pinning in the garbage collector
+
+* Support for numpy's ```object``` dtype via a garbage collector hook
+
+* Support for numpy.can_cast and numpy.min_scalar_type as well as beginning
+  a refactoring of the internal casting rules in numpy
+
+* Better support for numpy subtypes, via the __array_interface__,
+   __array_priority__, and __array_wrap__ methods (still a work-in-progress)
+
+* Better support for numpy ndarray.flags
+
+* Windows downloads now package a pypyw.exe in addition to pypy.exe
+
+* Add preliminary support for a new lightweight statistical profiler `vmprof2`_,
+  currently disabled until we work out the last JIT issues
+
+* Remove debug attributes from frames used in tracing, moving them to a debug
+  object created on demand
+
+* Internal refactoring and cleanups leading to improved JIT performance
+
+* Support for the PYTHONOPTIMIZE environment variable (impacting builtin's
+  __debug__ property)
+
+* We continue to improve the JIT's optimizations. Our benchmark suite is now
+  over 7 times faster than cpython
+
+* Issues reported with our previous release were resolved_ after reports from users on
+  our issue tracker at https://bitbucket.org/pypy/pypy/issues or on IRC at
+  #pypy.
+
+.. _`vmprof2`: https://vmprof.readthedocs.org
+.. _resolved: http://doc.pypy.org/en/latest/whatsnew-2.5.1.html
+
+Please try it out and let us know what you think. We welcome
+success stories, `experiments`_,  or `benchmarks`_, we know you are using PyPy, please tell us about it!
+
+Cheers
+

-issue2005:
-ignore errors on closing random file handles while importing a module (cpython compatibility)
 
-issue2013:
-added constants to _ssl for TLS 1.1 and 1.2
-
-issue2014:
-Add PyLong_FromUnicode to cpyext.
-
-issue2017: 
-On non-Linux-x86 platforms, reduced the memory impact of
-creating a lot of greenlets/tasklets.  Particularly useful on Win32 and
-on ARM, where you used to get a MemoryError after only 2500-5000
-greenlets (the 32-bit address space is exhausted).
-
-Update gdb_pypy for python3 (gdb comatability)
-
-Merged rstrategies into rpython which provides a library for Storage Strategies
-
-Support unicode strings in numpy.dtype creation i.e. np.dtype(u'int64')
-
-Various rpython cleanups for vmprof support
-
-issue2019:
-Fix isspace as called by rpython unicode.strip()
-
-issue2023:
-In the cpyext 'Concrete Object Layer' API,
-don't call methods on the object (which can be overriden),
-but directly on the concrete base type.
-
-issue2029:
-Hide the default_factory attribute in a dict
-
-issue2027:
-Better document pyinteractive and add --withmod-time
-
-.. branch: gc-incminimark-pinning-improve
-
-branch gc-incminimark-pinning-improve: 
-Object Pinning is now used in `bz2` and `rzlib` (therefore also affects
-Python's `zlib`). In case the data to compress/decompress is inside the nursery
-(incminimark) it no longer needs to create a non-moving copy of it. This saves
-one `malloc` and copying the data.  Additionally a new GC environment variable
-is introduced (`PYPY_GC_MAX_PINNED`) primarily for debugging purposes.
-
-.. branch: refactor-pycall
-
-branch refactor-pycall:
-Make `*`-unpacking in RPython function calls completely equivalent to passing
-the tuple's elements as arguments. In other words, `f(*(a, b))` now behaves 
-exactly like `f(a, b)`.
-
-.. branch: issue2018
-
-branch issue2018:
-Allow prebuilt rpython dict with function values
-
-.. branch: vmprof
-.. Merged but then backed out, hopefully it will return as vmprof2
-
-.. branch: object-dtype2
-
-branch object-dtype2:
-Extend numpy dtypes to allow using objects with associated garbage collection hook
-
-.. branch: vmprof2
-
-branch vmprof2:
-Add backend support for vmprof - a lightweight statistical profiler -
-to linux64, see client at https://vmprof.readthedocs.org
-
-.. branch: jit_hint_docs
-
-branch jit_hint_docs:
-Add more detail to @jit.elidable and @jit.promote in rpython/rlib/jit.py
-
-.. branch: remove-frame-debug-attrs
-
-branch remove_frame-debug-attrs:
-Remove the debug attributes from frames only used for tracing and replace
-them with a debug object that is created on-demand
-
-.. branch: can_cast
-
-branch can_cast:
-Implement np.can_cast, np.min_scalar_type and missing dtype comparison operations.
-
-.. branch: numpy-fixes

-Fix some error related to object dtype, non-contiguous arrays, inplement parts of 
-__array_interface__, __array_priority__, __array_wrap__
-
-.. branch: cells-local-stack

-Unify the PyFrame.cells and Pyframe.locals_stack_w lists, making frame objects
-1 or 3 words smaller.

 Highlights 
-==========
+===========
 
-* Improve support for TLS 1.1 and 1.2
+* Python compatibility:
 
-* Improved object pinning in the garbage collector
+  * Improve support for TLS 1.1 and 1.2
 
-* Support for numpy's ``object`` dtype via a garbage collector hook
+  * Windows downloads now package a pypyw.exe in addition to pypy.exe
 
-* Support for numpy.can_cast and numpy.min_scalar_type as well as beginning
-  a refactoring of the internal casting rules in numpy
+  * Support for the PYTHONOPTIMIZE environment variable (impacting builtin's
+    __debug__ property)
 
-* Better support for numpy subtypes, via the __array_interface__,
-  __array_priority__, and __array_wrap__ methods (still a work-in-progress)
+  * Issues reported with our previous release were resolved_ after reports from users on
+    our issue tracker at https://bitbucket.org/pypy/pypy/issues or on IRC at
+    #pypy.
 
-* Better support for numpy ndarray.flags
+* New features:
 
-* Windows downloads now package a pypyw.exe in addition to pypy.exe
+  * Add preliminary support for a new lightweight statistical profiler
+    `vmprof`_.
 
-* Add preliminary support for a new lightweight statistical profiler `vmprof2`_,
-  currently disabled until we work out the last JIT issues
+* Numpy:
 
-* Remove debug attributes from frames used in tracing, moving them to a debug
-  object created on demand
+  * Support for numpy's ``object`` dtype via a garbage collector hook
 
-* Internal refactoring and cleanups leading to improved JIT performance
+  * Support for numpy.can_cast and numpy.min_scalar_type as well as beginning
+    a refactoring of the internal casting rules in numpy
 
-* Support for the PYTHONOPTIMIZE environment variable (impacting builtin's
-  __debug__ property)
+  * Better support for numpy subtypes, via the __array_interface__,
+    __array_priority__, and __array_wrap__ methods (still a work-in-progress)
 
-* We continue to improve the JIT's optimizations. Our benchmark suite is now
-  over 7 times faster than cpython
+  * Better support for numpy ndarray.flags
 
-* Issues reported with our previous release were resolved_ after reports from users on
-  our issue tracker at https://bitbucket.org/pypy/pypy/issues or on IRC at
-  #pypy.
+* Performance improvements:
 
-.. _`vmprof2`: https://vmprof.readthedocs.org
+  * Slight improvement in frame sizes, improving some benchmarks
+
+  * Internal refactoring and cleanups leading to improved JIT performance
+
+  * Improved IO performance of ``zlib`` and ``bz2`` modules
+
+  * We continue to improve the JIT's optimizations. Our benchmark suite is now
+    over 7 times faster than cpython
+
+.. _`vmprof`: https://vmprof.readthedocs.org

 The next step is to create a buildslave configuration file. Based on version
 0.8.7 of buildbot you need to execute the following command.

Log:	Silence some warnings with gcc 5.1: if T is a type smaller than
	'int', then the C expression "condition ? (T)x : (T)y" is typed not
	as a T, but as a larger 'int' --- which means there was an implicit
	cast from the final 'int' to the T-typed target of the assignment
	whenever this macro was used.

Log:	Tweak: change 'structwrapper' to be used as a wrapper for all built-
	in functions, not only those that take a struct/union argument.
	This gives a nice place to store the function name, and give an
	error message that is the same as CPython in case of wrong number of
	arguments.

+=====
+
+* ffi.addressof(lib, "func_name") now returns a regular cdata object
+  of type "pointer to function".  You can use it on any function from a
+  library in API mode (in ABI mode, all functions are already regular
+  cdata objects).  To support this, you need to recompile your cffi

Log:	Under some unknown circumstance, it is possible to hit a path where
	a Branch instance doesn't have a "lineno" attribute, but we try to
	read it anyway. I've given up trying to figure out why it seems to
	occur (rarely) on top of PyPy but (apparently) not on top of
	CPython. Instead, always stick lineno and col_offset attributes,
	defaulting to 0.

 1.0.4
 =====
 
+* Issue #175: in ABI mode: we now support any constant declaration,
+  instead of only integers whose value is given in the cdef.  Such "new"
+  constants, i.e. either non-integers or without a value given in the
+  cdef, must correspond to actual symbols in the lib.  At runtime they
+  are looked up the first time we access them.  This is useful if the
+  library defines ``extern const sometype somename;``.
+
 * Issue #198: in API mode, if you declare constants of a ``struct``
   type, what you saw from lib.CONSTANT was corrupted.

Log:	hg merge 5acade5a80c5

	This is part of a series of commits to merge default into the py3k
	branch. The merge is very large, so it's easier when split into
	smaller pieces.

-As you can see, we successfully managed to call Python from C and C from
-Python. Now having one callback might not be enough, so what typically happens
-is that we would pass a struct full of callbacks to ``pypy_execute_source_ptr``
-and fill the structure from Python side for the future use.
+As you can see, what we did is create a ``struct API`` that contains
+the custom API that we need in our particular case.  This struct is
+filled by Python to contain a function pointer that is then called
+form the C side.  It is also possible to do have other function
+pointers that are filled by the C side and called by the Python side,
+or even non-function-pointer fields: basically, the two sides
+communicate via this single C structure that defines your API.
 
-Alternative example
--------------------
-
-As ``pypy_execute_source_ptr`` is not available in PyPy 2.2.1, you might want to try 
-an alternative approach which relies on -export-dynamic flag to the GNU linker. 
-The downside to this approach is that it is platform dependent.
-
-.. code-block:: c
-
-    #include "include/PyPy.h"
-    #include <stdio.h>
-
-    char source[] = "from cffi import FFI\n\
-    ffi = FFI()\n\
-    @ffi.callback('int(int)')\n\
-    def func(a):\n\
-        print 'Got from C %d' % a\n\
-        return a * 2\n\
-    ffi.cdef('int callback(int (*func)(int));')\n\
-    lib = ffi.verify('int callback(int (*func)(int));')\n\
-    lib.callback(func)\n\
-    print 'finished the Python part'\n\
-    ";
-
-    int callback(int (*func)(int))
-    {
-        printf("Calling to Python, result: %d\n", func(3));
-    }
-
-    int main()
-    {
-        int res;
-        void *lib, *func;
-
-        rpython_startup_code();
-        res = pypy_setup_home("/opt/pypy/bin/libpypy-c.so", 1);
-        if (res) {
-            printf("Error setting pypy home!\n");
-            return 1;
-        }
-        res = pypy_execute_source(source);
-        if (res) {
-            printf("Error calling pypy_execute_source!\n");
-        }
-        return res;
-    }
-
-
-Make sure to pass -export-dynamic flag when compiling::
-
-   $ gcc -g -o x x.c -lpypy-c -L. -export-dynamic
-   $ LD_LIBRARY_PATH=. ./x
-   Got from C 3
-   Calling to Python, result: 6
-   finished the Python part

   wrappers.  On PyPy we can't tell the difference, so

+* in pure Python, if you write ``class A(object): def f(self): pass``
+  and have a subclass ``B`` which doesn't override ``f()``, then
+  ``B.f(x)`` still checks that ``x`` is an instance of ``B``.  In
+  CPython, types written in C use a different rule.  If ``A`` is
+  written in C, any instance of ``A`` will be accepted by ``B.f(x)``
+  (and actually, ``B.f is A.f`` in this case).  Some code that could
+  work on CPython but not on PyPy includes:
+  ``datetime.datetime.strftime(datetime.date.today(), ...)`` (here,
+  ``datetime.date`` is the superclass of ``datetime.datetime``).
+  Anyway, the proper fix is arguably to use a regular method call in
+  the first place: ``datetime.date.today().strftime(...)``
+
 * the ``__dict__`` attribute of new-style classes returns a normal dict, as
   opposed to a dict proxy like in CPython. Mutating the dict will change the
   type and vice versa. For builtin types, a dictionary will be returned that

+Get gcc release 5.1.0 from the download page:
+    
+    https://gcc.gnu.org/mirrors.html
+
+Unpack it.
+
+Apply the patch provided here in the file gcc-5.1.0-patch.diff.
+
+You can either install the 'libmpc-dev' package on your system,
+or else, manually:
+    
+    * unpack 'https://ftp.gnu.org/gnu/gmp/gmp-6.0.0a.tar.xz'
+      and move 'gmp-6.0.0' as 'gcc-5.1.0/gmp'.
+
+    * unpack 'http://www.mpfr.org/mpfr-current/mpfr-3.1.2.tar.xz'
+      and move 'mpfr-3.1.2' as 'gcc-5.1.0/mpfr'
+
+    * unpack 'ftp://ftp.gnu.org/gnu/mpc/mpc-1.0.3.tar.gz'
+      and move 'mpc-1.0.3' as 'gcc-5.1.0/mpc'
+
+Compile gcc as usual:
+    
+    mkdir build
+    cd build
+    ../gcc-5.1.0/configure --enable-languages=c --disable-multilib
+    make    # or maybe only "make all-stage1-gcc"
+
+This patched gcc could be globally installed, but in these instructions
+we assume you don't want that.  Instead, create the following script,
+call it 'gcc-seg-gs', and put it in the $PATH:
+
+    #!/bin/bash
+    BUILD=/..../build      # <- insert full path
+    exec $BUILD/gcc/xgcc -B $BUILD/gcc "$@"

Subject: [pypy-commit] pypy stmgc-c7: Backed out changeset 4d93e7a10f91: gcc
 does some optimizations before
Message-ID: <20150530070403.BCD511C022E@cobra.cs.uni-duesseldorf.de>

Author: Armin Rigo <arigo at tunes.org>
Branch: stmgc-c7
Changeset: r77701:905ab5c077a5
Date: 2015-05-30 09:04 +0200
http://bitbucket.org/pypy/pypy/changeset/905ab5c077a5/

Log:	Backed out changeset 4d93e7a10f91: gcc does some optimizations
	before entering the RTL mode, and these optimizations seem prone to
	dropping the address space. In other words, it doesn't work at all

+ * In order to simplify the encoding process, the original linear magnitude
