	within the same block.

Log:	try to make the logic for building the result as similar as possible
	as the old _rawffi-based ctypes. Unfortunately this involves
	allocating a temp buffer just to do a type conversion, which is not
	very jit-friendly. However, this makes all tests passing, we will
	improve it later

+% Structuring a talk is a difficult task and the following structure
+% may not be suitable. Here are some rules that apply for this
+% solution: 
+
+% - Exactly two or three sections (other than the summary).
+% - At *most* three subsections per section.
+% - Talk about 30s to 2min per frame. So there should be between about
+%   15 and 30 frames, all told.
+
+% - A conference audience is likely to know very little of what you
+%   are going to talk about. So *simplify*!
+% - In a 20min talk, getting the main ideas across is hard
+%   enough. Leave out details, even if it means being less precise than
+%   you think necessary.
+% - If you omit details that are vital to the proof/implementation,
+%   just say so once. Everybody will be happy with that.

+      \item Hard to improve in an interpreter
+      \item Use a JIT compiler

+  \end{itemize}
+\end{frame}

+\begin{frame}
+  \frametitle{Context: The PyPy Project}
+  A general environment for implementing dynamic languages
+  \pause
+  \begin{block}{Approach}
+      \begin{itemize}
+          \item write an interpreter for the language in RPython
+          \item compilable to an efficient C-based VM
+          \pause

+  \end{block}
+\end{frame}
+
+\begin{frame}
+  \frametitle{PyPy's Tracing JIT}
+  the feature that makes PyPy interesting:
+  \begin{itemize}
+      \item a meta-JIT, applicable to many languages
+      \item needs a few source-code hints (or user annotations) in the interpreter
+      \item JIT is a tracing JIT compiler
+  \end{itemize}
+\end{frame}
+
+\begin{frame}
+  \frametitle{Tracing JITs}
+  \begin{itemize}
+      \item VM contains both an interpreter and the tracing JIT compiler
+      \item JIT works by observing and logging what the interpreter does
+      \item for interesting, commonly executed code paths
+      \item produces a linear list of operations (trace)
+      \item trace is optimized turned into machine code
+  \end{itemize}
+\end{frame}
+
+\begin{frame}[containsverbatim]
+  \frametitle{Example Trace}
+  Trace of \texttt{x = a + b; y = x + c}:
+\begin{verbatim}
+guard_class(a, Integer)
+guard_class(b, Integer)
+i1 = get(a, intval)
+i2 = get(b, intval)
+i3 = int_add(i1, i2)
+x = new(Integer)
+set(x, intval, i3)
+\end{verbatim}
+\pause

+i4 = get(x, intval)
+i5 = get(c, intval)
+i6 = int_add(i4, i5)
+y = new(Integer)
+set(y, intval, i6)
+\end{verbatim}
+\end{frame}
+
+\begin{frame}
+  \frametitle{Tracing JIT: Advantages}
+  \begin{itemize}
+      \item Traces are interesting linear pieces of code
+      \item most of the time correspond to loops
+      \item everything called in the trace is inlined
+      \item can perform good optimizations on the loop

-PyPy 1.4: Ouroboros in practice
+PyPy 1.4.1
 ===============================
 
-We're pleased to announce the 1.4 release of PyPy. This is a major breakthrough
-in our long journey, as PyPy 1.4 is the first PyPy release that can translate
-itself faster than CPython.  Starting today, we are using PyPy more for
-our every-day development.  So may you :) You can download it here:
+We're pleased to announce the 1.4.1 release of PyPy.  This
+release consolidates all the bug fixes that occurred since the
+previous release.  To everyone that took the trouble to report
+them, we want to say thank you.
 
     http://pypy.org/download.html
 
 What is PyPy
 ============
 
-PyPy is a very compliant Python interpreter, almost a drop-in replacement
-for CPython. It's fast (`pypy 1.4 and cpython 2.6`_ comparison)
+PyPy is a very compliant Python interpreter, almost a drop-in
+replacement for CPython.  Note that it still only emulates Python
+2.5 by default; the ``fast-forward`` branch with Python 2.7
+support is slowly getting ready but will only be integrated in
+the next release.
 
-Among its new features, this release includes numerous performance improvements
-(which made fast self-hosting possible), a 64-bit JIT backend, as well
-as serious stabilization. As of now, we can consider the 32-bit and 64-bit
-linux versions of PyPy stable enough to run `in production`_.
+In two words, the advantage of trying out PyPy instead of CPython
+(the default implementation of Python) is, for now, the
+performance.  Not all programs are faster in PyPy, but we are
+confident that any CPU-intensive task will be much faster, at
+least if it runs for long enough (the JIT has a slow warm-up
+phase, which can take several seconds or even one minute on the
+largest programs).
 
-Numerous speed achievements are described on `our blog`_. Normalized speed
-charts comparing `pypy 1.4 and pypy 1.3`_ as well as `pypy 1.4 and cpython 2.6`_
-are available on benchmark website. For the impatient: yes, we got a lot faster!
+Note again that we do support compiling and using C extension
+modules from CPython (``pypy setup.py install``).  However, this
+is still an alpha feature, and the most complex modules typically
+fail for various reasons; others work (e.g. ``PIL``) but take a
+serious performance hit.  Also, for Mac OS X see below.
+
+Please note also that PyPy's performance was optimized almost
+exclusively on Linux.  It seems from some reports that on Windows
+as well as Mac OS X (probably for different reasons) the
+performance might be lower.  We did not investigate much so far.
+
 
 More highlights
 ===============
 
-* PyPy's built-in Just-in-Time compiler is fully transparent and
-  automatically generated; it now also has very reasonable memory
-  requirements.  The total memory used by a very complex and
-  long-running process (translating PyPy itself) is within 1.5x to
-  at most 2x the memory needed by CPython, for a speed-up of 2x.
+* We migrated to Mercurial (thanks to Ronny Pfannschmidt and
+  Antonio Cuni) for the effort) and moved to bitbucket.  The new
+  command to check out a copy of PyPy is::
 
-* More compact instances.  All instances are as compact as if
-  they had ``__slots__``.  This can give programs a big gain in
-  memory.  (In the example of translation above, we already have
-  carefully placed ``__slots__``, so there is no extra win.)
+        hg clone http://bitbucket.org/pypy/pypy
 
-* `Virtualenv support`_: now PyPy is fully compatible with virtualenv_: note that
-  to use it, you need a recent version of virtualenv (>= 1.5).
+* In long-running processes, the assembler generated by old
+  JIT-compilations is now freed.  There should be no more leak,
+  however long the process runs.
 
-* Faster (and JITted) regular expressions - huge boost in speeding up
-  the `re` module.
+* Improve a lot the performance of the ``binascii`` module, and
+  of ``hashlib.md5`` and ``hashlib.sha``.
 
-* Other speed improvements, like JITted calls to functions like map().
+* Made sys.setrecursionlimit() a no-op.  Instead, we rely purely
+  on the built-in stack overflow detection mechanism, which also
+  gives you a RuntimeError -- just not at some exact recursion
+  level.

+* Fix argument processing (now e.g. ``pypy -OScpass`` works like
+  it does on CPython --- if you have a clue what it does there
+  ``:-)`` )
+
+* cpyext on Mac OS X: it still does not seem to work.  I get
+  systematically a segfault in dlopen().  Contributions welcome.
+
+* Fix two corner cases in the GC (one in minimark, one in
+  asmgcc+JIT).  This notably prevented "pypy translate.py -Ojit"
+  from working on Windows, leading to crashes.
+
+* Fixed a corner case in the JIT's optimizer, leading to "Fatal
+  RPython error: AssertionError".
+
+* Added some missing built-in functions into the 'os' module.
+
+* Fix ctypes (it was not propagating keepalive information from
+  c_void_p).

+its usefulness is limited to Python objects of type "long" that

Message-ID: <20110109135424.CE0F5282BDC@codespeak.net>

Changeset: r40524:532809e8da09
Date: 2011-01-09 14:54 +0100
http://bitbucket.org/pypy/pypy/changeset/532809e8da09/

Log:	Code explicitly the checks for overflow, now that the LLONG_xxx_OVF
	variant of the operations is no longer supported. Doing so helps
	the JIT too, at least so far.

	"sysconfig.project_base"

Log:	Distutils tests need this "sysconfig.project_base" CPython has more
	code to define it for Windows platforms, it's not needed on PyPy
	which has the same build system on all platforms (no PCBuild
	directory...)

 ===============================
-PyPy 1.4: Ouroboros in practice
+PyPy 1.4.1
 ===============================
 
-We're pleased to announce the 1.4 release of PyPy. This is a major breakthrough
-in our long journey, as PyPy 1.4 is the first PyPy release that can translate
-itself faster than CPython.  Starting today, we are using PyPy more for
-our every-day development.  So may you :) You can download it here:
+We're pleased to announce the 1.4.1 release of PyPy.  This
+release consolidates all the bug fixes that occurred since the
+previous release.  To everyone that took the trouble to report
+them, we want to say thank you.
 
     http://pypy.org/download.html
 
 What is PyPy
 ============
 
-PyPy is a very compliant Python interpreter, almost a drop-in replacement
-for CPython. It's fast (`pypy 1.4 and cpython 2.6`_ comparison)
+PyPy is a very compliant Python interpreter, almost a drop-in
+replacement for CPython.  Note that it still only emulates Python
+2.5 by default; the ``fast-forward`` branch with Python 2.7
+support is slowly getting ready but will only be integrated in
+the next release.
 
-Among its new features, this release includes numerous performance improvements
-(which made fast self-hosting possible), a 64-bit JIT backend, as well
-as serious stabilization. As of now, we can consider the 32-bit and 64-bit
-linux versions of PyPy stable enough to run `in production`_.
+In two words, the advantage of trying out PyPy instead of CPython
+(the default implementation of Python) is, for now, the
+performance.  Not all programs are faster in PyPy, but we are
+confident that any CPU-intensive task will be much faster, at
+least if it runs for long enough (the JIT has a slow warm-up
+phase, which can take several seconds or even one minute on the
+largest programs).
 
-Numerous speed achievements are described on `our blog`_. Normalized speed
-charts comparing `pypy 1.4 and pypy 1.3`_ as well as `pypy 1.4 and cpython 2.6`_
-are available on benchmark website. For the impatient: yes, we got a lot faster!
+Note again that we do support compiling and using C extension
+modules from CPython (``pypy setup.py install``).  However, this
+is still an alpha feature, and the most complex modules typically
+fail for various reasons; others work (e.g. ``PIL``) but take a
+serious performance hit.  Also, for Mac OS X see below.
+
+Please note also that PyPy's performance was optimized almost
+exclusively on Linux.  It seems from some reports that on Windows
+as well as Mac OS X (probably for different reasons) the
+performance might be lower.  We did not investigate much so far.
+
 
 More highlights
 ===============
 
-* PyPy's built-in Just-in-Time compiler is fully transparent and
-  automatically generated; it now also has very reasonable memory
-  requirements.  The total memory used by a very complex and
-  long-running process (translating PyPy itself) is within 1.5x to
-  at most 2x the memory needed by CPython, for a speed-up of 2x.
+* We migrated to Mercurial (thanks to Ronny Pfannschmidt and
+  Antonio Cuni) for the effort) and moved to bitbucket.  The new
+  command to check out a copy of PyPy is::
 
-* More compact instances.  All instances are as compact as if
-  they had ``__slots__``.  This can give programs a big gain in
-  memory.  (In the example of translation above, we already have
-  carefully placed ``__slots__``, so there is no extra win.)
+        hg clone http://bitbucket.org/pypy/pypy
 
-* `Virtualenv support`_: now PyPy is fully compatible with virtualenv_: note that
-  to use it, you need a recent version of virtualenv (>= 1.5).
+* In long-running processes, the assembler generated by old
+  JIT-compilations is now freed.  There should be no more leak,
+  however long the process runs.
 
-* Faster (and JITted) regular expressions - huge boost in speeding up
-  the `re` module.
+* Improve a lot the performance of the ``binascii`` module, and
+  of ``hashlib.md5`` and ``hashlib.sha``.
 
-* Other speed improvements, like JITted calls to functions like map().
+* Made sys.setrecursionlimit() a no-op.  Instead, we rely purely
+  on the built-in stack overflow detection mechanism, which also
+  gives you a RuntimeError -- just not at some exact recursion
+  level.

+* Fix argument processing (now e.g. ``pypy -OScpass`` works like
+  it does on CPython --- if you have a clue what it does there
+  ``:-)`` )
+
+* cpyext on Mac OS X: it still does not seem to work.  I get
+  systematically a segfault in dlopen().  Contributions welcome.
+
+* Fix two corner cases in the GC (one in minimark, one in
+  asmgcc+JIT).  This notably prevented "pypy translate.py -Ojit"
+  from working on Windows, leading to crashes.
+
+* Fixed a corner case in the JIT's optimizer, leading to "Fatal
+  RPython error: AssertionError".
+
+* Added some missing built-in functions into the 'os' module.
+
+* Fix ctypes (it was not propagating keepalive information from
+  c_void_p).
+

+# Assumptions
+# ===========
+#
+# For this to work some assumptions had to be made about the
+# optimizations performed. At least for the optimizations that are
+# allowed to operate across the loop boundaries. To enforce this, the
+# optimizer chain is recreated at the end of the preamble and only the
+# state of the optimizations that fulfill those assumptions are kept.
+# Since part of this state is stored in virtuals all OptValue objects
+# are also recreated to allow virtuals not supported to be forced.
+#
+# First of all, the optimizations are not allowed to introduce new
+# boxes. It is the unoptimized version of the trace that is inlined to 
+# form the second iteration of the loop. Otherwise the
+# state of the virtuals would not be updated correctly. Whenever some
+# box from the first iteration is reused in the second iteration, it
+# is added to the input arguments of the loop as well as to the
+# arguments of the jump at the end of the preamble. This means that
+# inlining the jump from the unoptimized trace will not work since it
+# contains too few arguments.  Instead the jump at the end of the
+# preamble is inlined. If the arguments of that jump contains boxes
+# that were produced by one of the optimizations, and thus never seen
+# by the inliner, the inliner will not be able to inline them. There
+# is no way of known what these boxes are supposed to contain in the
+# third iteration.
+#
+# The second assumption is that the state of the optimizer should be the
+# same after the second iteration as after the first. This have forced
+# us to disable store sinking across loop boundaries. Consider the
+# following trace
+#
+#         [p1, p2]
+#         i1 = getfield_gc(p1, descr=nextdescr)
+#         i2 = int_sub(i1, 1)
+#         i2b = int_is_true(i2)
+#         guard_true(i2b) []
+#         setfield_gc(p2, i2, descr=nextdescr)
+#         p3 = new_with_vtable(ConstClass(node_vtable))
+#         jump(p2, p3)
+#
+# At the start of the preamble, p1 and p2 will be pointers. The
+# setfield_gc will be removed by the store sinking heap optimizer, and
+# p3 will become a virtual. Jumping to the loop will make p1 a pointer
+# and p2 a virtual at the start of the loop. The setfield_gc will now
+# be absorbed into the virtual p2 and never seen by the heap
+# optimizer. At the end of the loop both p2 and p3 are virtuals, but
+# the loop needs p2 to be a pointer to be able to call itself. So it
+# is forced producing the operations 
+#
+#         p2 = new_with_vtable(ConstClass(node_vtable))
+#         setfield_gc(p2, i2, descr=nextdescr)
+#
+# In this case the setfield_gc is not store sinked, which means we are
+# not in the same state at the end of the loop as at the end of the
+# preamble. When we now call the loop again, the first 4 operations of
+# the trace were optimized under the wrong assumption that the
+# setfield_gc was store sinked which could lead to errors. In this
+# case what would happen is that it would be inserted once more in
+# front of the guard.

+UNROLLING
+---------
+ -  Replace full preamble with short preamble
+
+ -  Move forcings of the failargs of inlined guards into the mini
+    bridges
+
+ -  Reenable string optimizations in the preamble. This could be done
+    currently, but would not make much sense as all string virtuals would
+    be forced at the end of the preamble. Only the virtuals that
+    contains new boxes inserted by the optimization that can possible be
+    reused in the loops needs to be forced.
+
+ -  Loop invariant operations that might raise OverflowError should
+    be moved out of the loop. Currently only the guard checking if there
+    was an OverflowError raise are moved out.
+
+ -  The preamble of the second generated version of a loop 
+    is probably not needed if a short preamble was generated. It's
+    probably a better idea to have the mini bridges jump to the preamble
+    of the first generated version.
+
+ -  Fix bug causing test_mod in test_pypy_c.py to trace the loop every 
+    second iteration

  -  Fix bug causing test_mod in test_pypy_c.py to trace the loop every 
     second iteration
+
+ -  To remove more of the short preamble a lot more of the optimizer
+    state would have to be saved and inherited by the bridges. However
+    it should be possible to recreate much of this state from the short
+    preamble. To do that, the bridge have to know which of it's input
+    boxes corresponds to which of the output boxes (arguments of the
+    last jump) of the short preamble. One idea of how to store this
+    information is to introduce some VFromStartValue virtuals that
+    would be some pseudo virtuals containing a single input argument
+    box and it's index.

Date: 2011-01-12 09:34 +0100
http://bitbucket.org/pypy/pypy/changeset/84badb1fa1e9/

Log:	start the refactoring of _ffi to make it "shape-aware": the idea is
	that _ffi should be responsible to do the proper conversion between
	applevel and interp-level types, but to do so it needs more
	knowledge about the "shape": e.g., if the shape indicates a
	character, _ffi should expect a 1-lenght app-level string and
	convert it properly.

	So far, such kind of conversions were done inside _ctypes, which is
	now probably broken but will be fixed once the refactoring is
	complete

Log:	teach _ffi how to deal with structures by value: now you must pass
	directly the _rawffi.structure.W_StructureInstance object instead of
	the memory address where it resides; similarly, W_StructureInstance
	objects are returned instead of returning the memory address

Log:	yet another refactoring: in the end, it turns out that _ffi is
	probably not the right place where to put the knowledge about
	ctypes-style shapes (i.e., letters): it is enough to distinguish
	between app-level types and ffi-level types, which is what was
	missing before the initial refactoring

Log:	Start a small refactoring: kill the possibility to say
	"imm_fine=False" in llsupport/regalloc. The hope is that it will
	make using it less convoluted, because so far with "imm_fine=False"
	you get registers that will live dangerously shortly, and risk being
	overwritten by the next command.

+# Assumptions
+# ===========
+#
+# For this to work some assumptions had to be made about the
+# optimizations performed. At least for the optimizations that are
+# allowed to operate across the loop boundaries. To enforce this, the
+# optimizer chain is recreated at the end of the preamble and only the
+# state of the optimizations that fulfill those assumptions are kept.
+# Since part of this state is stored in virtuals all OptValue objects
+# are also recreated to allow virtuals not supported to be forced.
+#
+# First of all, the optimizations are not allowed to introduce new
+# boxes. It is the unoptimized version of the trace that is inlined to 
+# form the second iteration of the loop. Otherwise the
+# state of the virtuals would not be updated correctly. Whenever some
+# box from the first iteration is reused in the second iteration, it
+# is added to the input arguments of the loop as well as to the
+# arguments of the jump at the end of the preamble. This means that
+# inlining the jump from the unoptimized trace will not work since it
+# contains too few arguments.  Instead the jump at the end of the
+# preamble is inlined. If the arguments of that jump contains boxes
+# that were produced by one of the optimizations, and thus never seen
+# by the inliner, the inliner will not be able to inline them. There
+# is no way of known what these boxes are supposed to contain in the
+# third iteration.
+#
+# The second assumption is that the state of the optimizer should be the
+# same after the second iteration as after the first. This have forced
+# us to disable store sinking across loop boundaries. Consider the
+# following trace
+#
+#         [p1, p2]
+#         i1 = getfield_gc(p1, descr=nextdescr)
+#         i2 = int_sub(i1, 1)
+#         i2b = int_is_true(i2)
+#         guard_true(i2b) []
+#         setfield_gc(p2, i2, descr=nextdescr)
+#         p3 = new_with_vtable(ConstClass(node_vtable))
+#         jump(p2, p3)
+#
+# At the start of the preamble, p1 and p2 will be pointers. The
+# setfield_gc will be removed by the store sinking heap optimizer, and
+# p3 will become a virtual. Jumping to the loop will make p1 a pointer
+# and p2 a virtual at the start of the loop. The setfield_gc will now
+# be absorbed into the virtual p2 and never seen by the heap
+# optimizer. At the end of the loop both p2 and p3 are virtuals, but
+# the loop needs p2 to be a pointer to be able to call itself. So it
+# is forced producing the operations 
+#
+#         p2 = new_with_vtable(ConstClass(node_vtable))
+#         setfield_gc(p2, i2, descr=nextdescr)
+#
+# In this case the setfield_gc is not store sinked, which means we are
+# not in the same state at the end of the loop as at the end of the
+# preamble. When we now call the loop again, the first 4 operations of
+# the trace were optimized under the wrong assumption that the
+# setfield_gc was store sinked which could lead to errors. In this
+# case what would happen is that it would be inserted once more in
+# front of the guard.

     probably a better idea to have the mini bridges jump to the preamble
     of the first generated version.
 
- -  Fix bug causing test_mod in test_pypy_c.py to trace the loop every 
-    second iteration
+ -  Replace the list of short preambles with a tree, similar to the
+    tree formed by the full preamble and it's bridges. This should

  -  To remove more of the short preamble a lot more of the optimizer
     state would have to be saved and inherited by the bridges. However

	number object (and not e.g. a float). This is following CPython

--- Testcases for functions in cmath.
---
--- Each line takes the form:
---
--- <testid> <function> <input_value> -> <output_value> <flags>
---
--- where:
---
---   <testid> is a short name identifying the test,
---
---   <function> is the function to be tested (exp, cos, asinh, ...),
---
---   <input_value> is a pair of floats separated by whitespace
---     representing real and imaginary parts of a complex number, and
---
---   <output_value> is the expected (ideal) output value, again
---     represented as a pair of floats.
---
---   <flags> is a list of the floating-point flags required by C99
---
--- The possible flags are:
---
---   divide-by-zero : raised when a finite input gives a
---     mathematically infinite result.
---
---   overflow : raised when a finite input gives a finite result whose
---     real or imaginary part is too large to fit in the usual range
---     of an IEEE 754 double.
---
---   invalid : raised for invalid inputs.
---
---   ignore-real-sign : indicates that the sign of the real part of
---     the result is unspecified; if the real part of the result is
---     given as inf, then both -inf and inf should be accepted as
---     correct.
---
---   ignore-imag-sign : indicates that the sign of the imaginary part
---     of the result is unspecified.
---
--- Flags may appear in any order.
---
--- Lines beginning with '--' (like this one) start a comment, and are
--- ignored.  Blank lines, or lines containing only whitespace, are also
--- ignored.
-
--- The majority of the values below were computed with the help of
--- version 2.3 of the MPFR library for multiple-precision
--- floating-point computations with correct rounding.  All output
--- values in this file are (modulo yet-to-be-discovered bugs)
--- correctly rounded, provided that each input and output decimal
--- floating-point value below is interpreted as a representation of
--- the corresponding nearest IEEE 754 double-precision value.  See the
--- MPFR homepage at http://www.mpfr.org for more information about the
--- MPFR project.

--- rect: Conversion from polar coordinates to rectangular coordinates --
-------------------------------------------------------------------------
---
--- For cmath.rect, we can use the same testcase syntax as for the
--- complex -> complex functions above, but here the input arguments
--- should be interpreted as a pair of floating-point numbers rather
--- than the real and imaginary parts of a complex number.
---
--- Here are the 'spirit of C99' rules for rect.  First, the short
--- version:
---
---    rect(x, t) = exp(log(x)+it) for positive-signed x
---    rect(x, t) = -exp(log(-x)+it) for negative-signed x
---    rect(nan, t) = exp(nan + it), except that in rect(nan, +-0) the
---      sign of the imaginary part is unspecified.
---
--- and now the long version:
---
---   rect(x, -t) = conj(rect(x, t)) for all x and t
---   rect(-x, t) = -rect(x, t) for all x and t
---   rect(+0, +0) returns +0 + i0
---   rect(+0, inf) returns +- 0 +- i0, where the signs of the real and
---     imaginary parts are unspecified.
---   rect(x, inf) returns NaN + i NaN and raises the "invalid"
---     floating-point exception, for finite nonzero x.
---   rect(inf, inf) returns +-inf + i NaN and raises the "invalid"
---     floating-point exception (where the sign of the real part of the
---     result is unspecified).
---   rect(inf, +0) returns inf+i0
---   rect(inf, x) returns inf*cis(x), for finite nonzero x
---   rect(inf, NaN) returns +-inf+i NaN, where the sign of the real part
---     of the result is unspecified.
---   rect(NaN, x) returns NaN + i NaN for all nonzero numbers (including
---     infinities) x
---   rect(NaN, 0) returns NaN +- i0, where the sign of the imaginary
---     part is unspecified
---   rect(NaN, NaN) returns NaN + i NaN
---   rect(x, NaN) returns NaN + i NaN for finite nonzero x
---   rect(+0, NaN) return +-0 +- i0, where the signs of the real and
---     imaginary parts are unspecified.

Log:	fix test_numbers: neither the array nor the struct modules support
	the new "g" typecode for long doubles. The fix is to just skip the
	testcase when we need struct, and to use a _rawffi.Array instead of
	an array.array

Log:	add a poor's man "xfail" to ctypes test, and mark all known-to-fail
	ones. This way, it will be easier to spot "real" regressions in
	jitypes2. There is also a new "test_no_more_xfail" test that will
	fail until all xfail will be removed, so we don't forget about them

-"""
-configurable per-test stdout/stderr capturing mechanisms. 
-
-This plugin captures stdout/stderr output for each test separately. 
-In case of test failures this captured output is shown grouped 
-togtther with the test. 
-
-The plugin also provides test function arguments that help to
-assert stdout/stderr output from within your tests, see the 
-`funcarg example`_. 
-
-
-Capturing of input/output streams during tests 
----------------------------------------------------
-
-By default ``sys.stdout`` and ``sys.stderr`` are substituted with
-temporary streams during the execution of tests and setup/teardown code.  
-During the whole testing process it will re-use the same temporary 
-streams allowing to play well with the logging module which easily
-takes ownership on these streams. 
-
-Also, 'sys.stdin' is substituted with a file-like "null" object that 
-does not return any values.  This is to immediately error out
-on tests that wait on reading something from stdin. 
-
-You can influence output capturing mechanisms from the command line::
-
-    py.test -s            # disable all capturing
-    py.test --capture=sys # replace sys.stdout/stderr with in-mem files
-    py.test --capture=fd  # point filedescriptors 1 and 2 to temp file
-
-If you set capturing values in a conftest file like this::
-
-    # conftest.py
-    option_capture = 'fd'
-
-then all tests in that directory will execute with "fd" style capturing. 
-
-sys-level capturing 
-------------------------------------------
-
-Capturing on 'sys' level means that ``sys.stdout`` and ``sys.stderr`` 
-will be replaced with in-memory files (``py.io.TextIO`` to be precise)  
-that capture writes and decode non-unicode strings to a unicode object
-(using a default, usually, UTF-8, encoding). 
-
-FD-level capturing and subprocesses
-------------------------------------------
-
-The ``fd`` based method means that writes going to system level files
-based on the standard file descriptors will be captured, for example 
-writes such as ``os.write(1, 'hello')`` will be captured properly. 
-Capturing on fd-level will include output generated from 
-any subprocesses created during a test. 
-
-.. _`funcarg example`:
-
-Example Usage of the capturing Function arguments
----------------------------------------------------
-
-You can use the `capsys funcarg`_ and `capfd funcarg`_ to 
-capture writes to stdout and stderr streams.  Using the
-funcargs frees your test from having to care about setting/resetting 
-the old streams and also interacts well with py.test's own 
-per-test capturing.  Here is an example test function:
-
-.. sourcecode:: python
-
-    def test_myoutput(capsys):
-        print ("hello")
-        sys.stderr.write("world\\n")
-        out, err = capsys.readouterr()
-        assert out == "hello\\n"
-        assert err == "world\\n"
-        print "next"
-        out, err = capsys.readouterr()
-        assert out == "next\\n" 
-
-The ``readouterr()`` call snapshots the output so far - 
-and capturing will be continued.  After the test 
-function finishes the original streams will 
-be restored.  If you want to capture on 
-the filedescriptor level you can use the ``capfd`` function
-argument which offers the same interface.

-collect and execute doctests from modules and test files. 
-
-Usage
--------------
-
-By default all files matching the ``test*.txt`` pattern will 
-be run through the python standard ``doctest`` module.  Issue::
-
-    py.test --doctest-glob='*.rst'
-
-to change the pattern.  Additionally you can trigger running of
-tests in all python modules (including regular python test modules)::
-
-    py.test --doctest-modules
-
-You can also make these changes permanent in your project by 
-putting them into a conftest.py file like this::
-
-    # content of conftest.py 
-    option_doctestmodules = True
-    option_doctestglob = "*.rst"

-
-* setup and teardown at module/class/method level
-* SkipTest exceptions and markers 
-* setup/teardown decorators
-* yield-based tests and their setup 
-* general usage of nose utilities

-"""
-generic mechanism for marking python functions. 
-
-By using the ``py.test.mark`` helper you can instantiate
-decorators that will set named meta data on test functions. 
-
-Marking a single function 
-----------------------------------------------------
-
-You can "mark" a test function with meta data like this::
-
-    @py.test.mark.webtest
-    def test_send_http():
-        ... 
-
-This will set a "Marker" instance as a function attribute named "webtest". 
-You can also specify parametrized meta data like this::
-
-    @py.test.mark.webtest(firefox=30)
-    def test_receive():
-        ...
-
-The named marker can be accessed like this later::
-
-    test_receive.webtest.kwargs['firefox'] == 30
-
-In addition to set key-value pairs you can also use positional arguments::
-
-    @py.test.mark.webtest("triangular")
-    def test_receive():
-        ...
-
-and later access it with ``test_receive.webtest.args[0] == 'triangular``.
-
-.. _`scoped-marking`:
-
-Marking whole classes or modules 
-----------------------------------------------------
-
-If you are programming with Python2.6 you may use ``py.test.mark`` decorators
-with classes to apply markers to all its test methods::
-
-    @py.test.mark.webtest
-    class TestClass:
-        def test_startup(self):
-            ...
-        def test_startup_and_more(self):
-            ...
-
-This is equivalent to directly applying the decorator to the
-two test functions. 
-
-To remain compatible with Python2.5 you can also set a 
-``pytestmark`` attribute on a TestClass like this::
-
-    import py
-
-    class TestClass:
-        pytestmark = py.test.mark.webtest
-
-or if you need to use multiple markers you can use a list::
-
-    import py
-
-    class TestClass:
-        pytestmark = [py.test.mark.webtest, pytest.mark.slowtest]
-
-You can also set a module level marker::
-
-    import py
-    pytestmark = py.test.mark.webtest
-
-in which case it will be applied to all functions and 
-methods defined in the module.  
-
-Using "-k MARKNAME" to select tests
-----------------------------------------------------
-
-You can use the ``-k`` command line option to select
-tests::
-
-    py.test -k webtest  # will only run tests marked as webtest
-

-helpers for asserting deprecation and other warnings. 
-
-Example usage 
----------------------
-
-You can use the ``recwarn`` funcarg to track 
-warnings within a test function:
-
-.. sourcecode:: python
-
-    def test_hello(recwarn):
-        from warnings import warn
-        warn("hello", DeprecationWarning)
-        w = recwarn.pop(DeprecationWarning)
-        assert issubclass(w.category, DeprecationWarning)
-        assert 'hello' in str(w.message)
-        assert w.filename
-        assert w.lineno
-
-You can also call a global helper for checking
-taht a certain function call yields a Deprecation
-warning:
-
-.. sourcecode:: python
-
-    import py
-            
-    def test_global():
-        py.test.deprecated_call(myfunction, 17)

-safely patch object attributes, dicts and environment variables. 
-
-Usage 
-----------------
-
-Use the `monkeypatch funcarg`_ to tweak your global test environment 
-for running a particular test.  You can safely set/del an attribute, 
-dictionary item or environment variable by respective methods
-on the monkeypatch funcarg.  If you want e.g. to set an ENV1 variable 
-and have os.path.expanduser return a particular directory, you can 
-write it down like this:
-
-.. sourcecode:: python 
-
-    def test_mytest(monkeypatch):
-        monkeypatch.setenv('ENV1', 'myval')
-        monkeypatch.setattr(os.path, 'expanduser', lambda x: '/tmp/xyz')
-        ... # your test code that uses those patched values implicitely
-
-After the test function finished all modifications will be undone, 
-because the ``monkeypatch.undo()`` method is registered as a finalizer. 
-
-``monkeypatch.setattr/delattr/delitem/delenv()`` all 
-by default raise an Exception if the target does not exist. 
-Pass ``raising=False`` if you want to skip this check. 
-
-prepending to PATH or other environment variables 
----------------------------------------------------------
-
-To prepend a value to an already existing environment parameter:
-
-.. sourcecode:: python 
-
-    def test_mypath_finding(monkeypatch):
-        monkeypatch.setenv('PATH', 'x/y', prepend=":")
-        # in bash language: export PATH=x/y:$PATH 
-
-calling "undo" finalization explicitely
------------------------------------------
-
-At the end of function execution py.test invokes
-a teardown hook which undoes all monkeypatch changes. 
-If you do not want to wait that long you can call 
-finalization explicitely::
-
-    monkeypatch.undo()  
-
-This will undo previous changes.  This call consumes the
-undo stack.  Calling it a second time has no effect unless
-you  start monkeypatching after the undo call. 
-
-.. _`monkeypatch blog post`: http://tetamap.wordpress.com/2009/03/03/monkeypatching-in-unit-tests-done-right/

-"""
-advanced skipping for python test functions, classes or modules.
-
-With this plugin you can mark test functions for conditional skipping 
-or as "xfail", expected-to-fail.  Skipping a test will avoid running it
-while xfail-marked tests will run and result in an inverted outcome:
-a pass becomes a failure and a fail becomes a semi-passing one. 
-
-The need for skipping a test is usually connected to a condition.  
-If a test fails under all conditions then it's probably better
-to mark your test as 'xfail'. 
-
-By passing ``-rxs`` to the terminal reporter you will see extra
-summary information on skips and xfail-run tests at the end of a test run. 
-
-.. _skipif:
-
-Skipping a single function 
--------------------------------------------
-
-Here is an example for marking a test function to be skipped
-when run on a Python3 interpreter::
-
-    @py.test.mark.skipif("sys.version_info >= (3,0)")
-    def test_function():
-        ...
-
-During test function setup the skipif condition is 
-evaluated by calling ``eval(expr, namespace)``.  The namespace
-contains the  ``sys`` and ``os`` modules and the test 
-``config`` object.  The latter allows you to skip based 
-on a test configuration value e.g. like this::
-
-    @py.test.mark.skipif("not config.getvalue('db')")
-    def test_function(...):
-        ...
-
-Create a shortcut for your conditional skip decorator 
-at module level like this::
-
-    win32only = py.test.mark.skipif("sys.platform != 'win32'")
-
-    @win32only
-    def test_function():
-        ...
-
-
-skip groups of test functions 
---------------------------------------
-
-As with all metadata function marking you can do it at
-`whole class- or module level`_.  Here is an example 
-for skipping all methods of a test class based on platform::
-
-    class TestPosixCalls:
-        pytestmark = py.test.mark.skipif("sys.platform == 'win32'")
-    
-        def test_function(self):
-            # will not be setup or run under 'win32' platform
-            #
-
-The ``pytestmark`` decorator will be applied to each test function.
-If your code targets python2.6 or above you can equivalently use 
-the skipif decorator on classes::
-
-    @py.test.mark.skipif("sys.platform == 'win32'")
-    class TestPosixCalls:
-    
-        def test_function(self):
-            # will not be setup or run under 'win32' platform
-            #
-
-It is fine in general to apply multiple "skipif" decorators
-on a single function - this means that if any of the conditions
-apply the function will be skipped. 
-
-.. _`whole class- or module level`: mark.html#scoped-marking
-
-
-mark a test function as **expected to fail**
--------------------------------------------------------
-
-You can use the ``xfail`` marker to indicate that you
-expect the test to fail:: 
-
-    @py.test.mark.xfail
-    def test_function():
-        ...
-
-This test will be run but no traceback will be reported
-when it fails. Instead terminal reporting will list it in the
-"expected to fail" or "unexpectedly passing" sections.
-
-Same as with skipif_ you can also selectively expect a failure
-depending on platform::
-
-    @py.test.mark.xfail("sys.version_info >= (3,0)")
-    def test_function():
-        ...
-
-To not run a test and still regard it as "xfailed"::
-
-    @py.test.mark.xfail(..., run=False)
-
-To specify an explicit reason to be shown with xfailure detail::
-
-    @py.test.mark.xfail(..., reason="my reason")
-
-imperative xfail from within a test or setup function
-------------------------------------------------------
-
-If you cannot declare xfail-conditions at import time
-you can also imperatively produce an XFail-outcome from 
-within test or setup code.  Example::
-
-    def test_function():
-        if not valid_config():
-            py.test.xfail("unsuppored configuration")
-
-
-skipping on a missing import dependency
---------------------------------------------------
-
-You can use the following import helper at module level 
-or within a test or test setup function::
-
-    docutils = py.test.importorskip("docutils")
-
-If ``docutils`` cannot be imported here, this will lead to a
-skip outcome of the test.  You can also skip dependeing if
-if a library does not come with a high enough version::
-
-    docutils = py.test.importorskip("docutils", minversion="0.3")
-
-The version will be read from the specified module's ``__version__`` attribute.
-
-imperative skip from within a test or setup function
-------------------------------------------------------
-
-If for some reason you cannot declare skip-conditions
-you can also imperatively produce a Skip-outcome from 
-within test or setup code.  Example::
-
-    def test_function():
-        if not valid_config():
-            py.test.skip("unsuppored configuration")

Log:	On Windows, eci.compile_shared_lib() will now build a DLL when there
	are "exported symbols", even when there are no source files. This
	allows ll2ctypes to call functions in static libraries, and
	module/_ssl/test now works on windows.

Log:	Fix unicodedata on narrow unicode builds (sizeof w_char_t == 2): the
	unicode database accepts chars from the entire Unicode range.

	For characters outside the BMP, a surrogate pair is used and the
	resulting unicode has a length of two.

Log:	When EINTR is raised, the application has received a signal; give

	I'm not sure how to test this in RPython. CPython has the same call
	in PyErr_SetFromErrno(). This change should unblock test_io.py.

Log:	Oups. Sorry dcolish, I also implemented W_Permutations two days ago
	but was on a train ride and can only check it in now. Sorry, I
	think I will remove your version, because mine is a bit more
	efficient: there is less copying of lists around.

Log:	alternative approach to make ctypes call fast: first, we try to call
	the underlying _ffi function: if we get a TypeError, it means that
	_ffi could not convert the argument and we rollback to the slow
	version with full argument conversions.

	Obviosuly, it is fast as long as the _ffi module is able to
	correctly convert the arguments: so far, only simple types are
	supported, but it should be possible to add more cases

Log:	Port fix (and test) of simplejson issue #57 to stdlib json library.
	The bug is that loads('{}') gives [] instead of {}
	http://code.google.com/p/simplejson/issues/detail?id=57

	This issue doesn't arise in CPython 2.7.0 because it doesn't exist
	in the _json C implementation that it uses to replace of the pure
	Python implementation with the bug.
