Don't use SEH when compiling wth mingw.
Use IS_INTRESOURCE to determine function name from function ordinal.
Rewrite the code that allocates and frees callback functions, hopefully
this avoids the coverty warnings: Remove the THUNK typedef, and move the
definition of struct ffi_info into the header file.

test_capi.py: A test module should never spawn a thread as
a side effect of being imported. Because this one did, the
segfault one of its thread tests caused didn't occur until
a few tests after test_regrtest.py thought test_capi was
finished. Repair that. Also join() the thread spawned
at the end, so that test_capi is truly finished when
regrtest reports that it's done.
_testcapimodule.c test_thread_state(): this spawns a
couple of non-threading.py threads, passing them a PyObject*
argument, but did nothing to ensure that those threads
finished before returning. As a result, the PyObject*
_could_ (although this was unlikely) get decref'ed out of
existence before the threads got around to using it.
Added explicit synchronization (via a Python mutex) so
that test_thread_state can reliably wait for its spawned
threads to finish.
This was a fair amount of rework of the patch. Refactored test_fork1 so it
could be reused by the new tests for wait3/4. Also made them into new style
unittests (derive from unittest.TestCase).
This patch adds a-LAW encoding to audioop and replaces the old
u-LAW encoding/decoding code with the current code from sox.
Possible issues: the code from sox uses int16_t.

This will hopefully get rid of some Coverity warnings, be a hint to
developers, and be marginally faster.
Some asserts were added when the type is currently known, but depends
on values from another function.

The attached patch fixes all the ctypes tests so they pass on amd64.
It also fixes several warnings. I'm not sure what else to do with the
patch. Let me know how you want to handle these in the future.
I'm not sure the patch is 100% correct. You will need to decide what
can be 64 bits and what can't. I believe
sq_{item,slice,ass_item,ass_slice} all need to use Py_ssize_t. The
types in ctypes.h may not require all the changes I made. I don't
know how you want to support older version, so I unconditionally
changed the types to Py_ssize_t.

The patch is also in the ctypes SVN repository now, after small
changes to add compatibility with older Python versions.
PyObject_Unicode(). This problem was originally reported from Coverity
and addresses mail on python-dev "checkin r43015".
This inlines the conversion of the string to unicode and cleans
up/simplifies some code at the end of the PyObject_Unicode().
We really need a complete C API test module for all public APIs
and passing good and bad parameter values.
Will backport.
Anyway, this is the changes to the with-statement
so that __exit__ must return a true value in order
for a pending exception to be ignored.
The PEP (343) is already updated.
missing PyObject_Del()'s, simplify some code by using Py_BuildValue()
instead of creating a tuple with items manually, stop clobbering builtin
exceptions in a few places, and guard against NULL-returning functions some
more.
This fixes 117 of the 780 (!?!#%@#$!!) reference leaks in test_bsddb3. I
ain't not done yet, although this review of 5kloc was just the easy part.
an error code, this let `self` leak. This is a disaster
on Windows, since `self` already points to a newly-opened
file object, and it was impossible for Python code to
close the thing since the only reference to it was in a
blob of leaked C memory.
test_hotshot test_bad_sys_path(): This new test provoked
the C bug above. This test passed, but left an open
"@test" file behind, which caused a massive cascade of
bogus test failures in later, unrelated tests on Windows.
Changed the test code to remove the @test file it leaves
behind, which relies on the change above to close that
file first.

actual value of the Py_ssize_t variable is way below 31 bits. I suspect

the sentinel value in the main function, rather than the helper. This
function could possibly do with an early-out if any of the helper calls ends
up with a len of 0, but I doubt it really matters (how common are malformed

posix__getfullpathname().
In partial answer to the now-deleted XXX comment:
/* XXX(twouters) Why use 'et#' here at all? insize isn't used */
`insize` is an input parameter too, and it was left uninitialized,
leading to seemingly random failures.
non-32bit platforms. Will still only allow 32 bits in a timestamp on Win64,
but at least it won't crash, and it'll work right on platforms where longs
are big enough to contain time_t's.
(A better-working, although conceptually less-right fix would have been to
use Py_ssize_t here, but Martin and Tim won't let me.)
- New semantics for __exit__() -- it must re-raise the exception
if type is not None; the with-statement itself doesn't do this.
(See the updated PEP for motivation.)
- Added context managers to:
- file
- thread.LockType
- threading.{Lock,RLock,Condition,Semaphore,BoundedSemaphore}
- decimal.Context
- Added contextlib.py, which defines @contextmanager, nested(), closing().
- Unit tests all around; bot no docs yet.
- IMPORT_NAME takes an extra argument from the stack: the relativeness of
the import. Only passed to __import__ when it's not -1.
- __import__() takes an optional 5th argument for the same thing; it
__defaults to -1 (old semantics: try relative, then absolute)
- 'from . import name' imports name (be it module or regular attribute)
from the current module's *package*. Likewise, 'from .module import name'
will import name from a sibling to the current module.
- Importing from outside a package is not allowed; 'from . import sys' in a
toplevel module will not work, nor will 'from .. import sys' in a
(single-level) package.
- 'from __future__ import absolute_import' will turn on the new semantics
for import and from-import: imports will be absolute, except for
from-import with dots.
Includes tests for regular imports and importhooks, parser changes and a
NEWS item, but no compiler-package changes or documentation changes.
- The copy module now "copies" function objects (as atomic objects).
- dict.__getitem__ now looks for a __missing__ hook before raising
KeyError.
- Added a new type, defaultdict, to the collections module.
This uses the new __missing__ hook behavior added to dict (see above).
On a box where sizeof(size_t) == 4, C doesn't define
what happens when a size_t value is shifted right by
32 bits, and this caused test_mmap to fail on Windows
in a debug build. So use different code to break
the size apart depending on how large size_t actually
is.
This looks like an illusion, since lots of code in this
module still appears to assume sizes can't be more
than 32 bits (e.g., the internal _GetMapSize() still
returns an int), but at least test_mmap passes again.
has been applied fairly arbitrarily in this module (nsmallest uses
Py_ssize_t, nlargest does not) and it probably deserves a more complete
review. Fixes heapq.nsmallest() always returning the empty list (on
platforms with 64-bit ssize_t/long)

History in svn repo: http://codespeak.net/svn/user/arigo/hack/misc/lsprof
* Module/_lsprof.c is the internal C module, Lib/cProfile.py a wrapper.
* pstats.py updated to display cProfile's caller/callee timings if available.
* setup.py and NEWS updated.
* documentation updates in the profiler section:
- explain the differences between the three profilers that we have now
- profile and cProfile can use a unified documentation, like (c)Pickle
- mention that hotshot is "for specialized usage" now
- removed references to the "old profiler" that no longer exists
* test updates:
- extended test_profile to cover delicate cases like recursion
- added tests for the caller/callee displays
- added test_cProfile, performing the same tests for cProfile
* TO-DO:
- cProfile gives a nicer name to built-in, particularly built-in methods,
which could be backported to profile.
- not tested on Windows recently!

This can only be acheived with ulimit -n SOME_NUMBER_BIGGER_THAN_FD_SETSIZE
which is typically only available to root. Since this wouldn't normally
be run in a test (ie, run as root), it doesn't seem too worthwhile to
add a normal test. The bug report has one version of a test. I've
written another. Not sure what the best thing to do is.
Do the check before calling internal_select() because we can't set
an error in between Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS.
This seemed the clearest solution, ie handle before calling internal_select()
rather than inside. Plus there is at least one place outside
of internal_select() that needed to be handled.
Will backport.
on both Unix (SVR4 and BSD) and Windows. Restores behaviour of passing -1
for anonymous memory on Unix. Use MAP_ANONYMOUS instead of _ANON since
the latter is deprecated according to Linux (gentoo) man pages.
Should we continue to allow mmap.mmap(0, length) to work on Windows?
0 is a valid fd.
Will backport bugfix portions.
