Add a new function uses_seh() to the _ctypes extension module. This

used when calling functions, False otherwise.
of bugs in that port. The most annoying ones were due to some subtle differences
between the document ABI and the actual implementation :-(
(there are no python unittests that fail without this patch, but without it
some of libffi's unittests fail).
will return True if Windows Structured Exception handling (SEH) is
used when calling functions, False otherwise.
Currently, only MSVC supports SEH.
Fix the test so that it doesn't crash when run with MingW compiled
_ctypes. Note that two tests are still failing when mingw is used, I
suspect structure layout differences and function calling conventions
between MSVC and MingW.
It seems that the definition of '__attribute__(x)' was responsible for
the compiler ignoring the '__fastcall' attribute on the
ffi_closure_SYSV function in libffi_msvc/ffi.c, took me quite some
time to figure this out.
handler would cause a segfault. This merges in Expat's lib/xmlparse.c
revisions 1.154 and 1.155, which fix this and a closely related problem
(the later does not affect Python).
Moved the crasher test to the tests for xml.parsers.expat.
This backs out the test changes in 46962 which prevented crashes
by not running the tests via a version check. All the version checks
added in that rev were removed from the tests.
Code was added to the error handler in connection.c that seems
to work with older versions of sqlite including 3.1.3.
SQLite versions.
- Added version checks in test suite so that we don't execute tests that we
know will fail with older (buggy) SQLite versions.
Now, all tests should run against all SQLite versions from 3.0.8 until 3.3.6
(latest one now). The sqlite3 module can be built against all these SQLite
versions and the sqlite3 module does its best to not trigger bugs in SQLite,
but using SQLite 3.3.3 or later is recommended.
Heavily revised, comprising revisions:
46640 - original trunk revision (backed out in r46655)
46647 - markup fix (backed out in r46655)
46692:46918 merged from branch aimacintyre-sf1454481
branch tested on buildbots (Windows buildbots had problems
not related to these changes).
Summary of changes:
- support for 'variable sized' data
- support for anonymous structure/union fields
- fix severe bug with certain arrays or structures containing more than 256 fields
the char buffer was requested. Now it actually returns the char buffer if
available or raises a TypeError if it isn't (as is raised for the other buffer
types if they are not present but requested).
Not a backport candidate since it does change semantics of the buffer object
(although it could be argued this is enough of a bug to bother backporting).
endian machines. Should fix the remaininf failure in the PPC64
Debian buildbot.
Thanks to Matthias Klose for providing access to a machine to debug
and test this.
parameter strings") changed this function's signature
seemingly by mistake, which is causing buildbots to fail
test_bsddb3. Restored the pre-46688 signature.
structmember typecode for Py_ssize_t fields. This should fix some of
the errors on the PPC64 debian machine (64-bit, big endian).
Assigning to readonly fields now raises AttributeError instead of
TypeError, so the testcase has to be changed as well.
in BerkeleyDB >= 4.2 it tried to construct a list out of an uninitialized
char **log_list.
feature: export the DB_ARCH_REMOVE flag by name in the module on BerkeleyDB >= 4.2.
46640 Patch #1454481: Make thread stack size runtime tunable.
46647 Markup fix
The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them. See python-dev discussion.
Note that a branch can (and should) be created for resolving these
problems, like
svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH
followed by merging rev 46647 to the new branch.
- Following Guido's comments, renamed
* pack_to -> pack_into
* recv_buf -> recv_into
* recvfrom_buf -> recvfrom_into
- Made fixes to _struct.c according to Neal Norwitz comments on the checkins
list.
- Converted some ints into the appropriate -- I hope -- ssize_t and size_t.
Fix by renaming the variable.
In a different module, Neal fixed it by renaming _self to self. There's
already a variable named 'self' here, so I used selfptr.
(I'm committing this on a Mac without Tk, but it's a simple search-and-replace.
<crosses fingers>, so I'll watch the buildbots and see what happens.)
Renames functional extension module to _functools and adds a Python
functools module so that utility functions like update_wrapper can be
added easily.
* Added socket.recv_buf() and socket.recvfrom_buf() methods, that use the buffer
protocol (send and sendto already did).
* Added struct.pack_to(), that is the corresponding buffer compatible method to
unpack_from().
* Fixed minor typos in arraymodule.
QueryPerformanceCounter(), but we believe Win64 does
support it now. So use in time.clock().
It would be peachy if someone with a Win64 box tried
this ;-)
about "%u", "%lu" and "%zu" formats.
Since PyString_FromFormat and PyErr_Format have exactly the same rules
(both inherited from PyString_FromFormatV), it would be good if someone
with more LaTeX Fu changed one of them to just point to the other.
Their docs were way out of synch before this patch, and I just did a
mass copy+paste to repair that.
Not a backport candidate (this is a new feature).
longobject.c: also fix an ssize_t problem
<a> could have been NULL, so hoist the size calc to not use <a>.
_ssl.c: under fail: self is DECREF'd, but it would have been NULL.
_elementtree.c: delete self if there was an error.
_csv.c: I'm not sure if lineterminator could have been anything other than
a string. However, other string method calls are checked, so check this
one too.
discussion.
There are two places of documentation that still mention __context__:
Doc/lib/libstdtypes.tex -- I wasn't quite sure how to rewrite that without
spending a whole lot of time thinking about it; and whatsnew, which Andrew
usually likes to change himself.
The problem was that pyconfig.h was being included before some system headers
which caused redefinitions and other breakage. This moves system headers
after expat_config.h which includes pyconfig.h.
After the patch (45590) to add extra debug stats to the gc module, Python
was crashing on OpenBSD due to:
Fatal Python error: Interpreter not initialized (version mismatch?)
This seems to occur due to calling collect() when initialized (in pythonrun.c)
is set to 0. Now, the import will occur in the init function which
shouldn't suffer this problem.
MAXPATHLEN-sized buffers for various output-buffers (like to realpath()),
and that's correct on BSD platforms, but not Linux (which uses PATH_MAX, and
does not define MAXPATHLEN.) Cursory googling suggests Linux is following a
newer standard than BSD, but in cases like this, who knows. Using the
greater of PATH_MAX and 1024 as a fallback for MAXPATHLEN seems to be the
most portable solution.
AF_PACKET cases in getsockaddrarg were missing their own checks for
tuple-ness of the address argument, which means a confusing SystemError was
raised by PyArg_ParseTuple instead.
The new char-array used in ioctl calls wasn't explicitly NUL-terminated;
quite probably the cause for the test_pty failures on Solaris that we
circumvented earlier. (I wasn't able to reproduce it with this patch, but it
has been somewhat elusive to start with.)
This patch checks if poll is broken when the select module is loaded instead
of doing so at configure-time. This functionality is only active on Mac OS X.
This patch causes several symbols in the socket and posix module to be weakly
linked on OSX and disables usage of ftime on OSX. These changes make it possible
to use a binary build on OSX 10.4 on a 10.3 system.
I tested this with valgrind on amd64.
The man pages I found for diff architectures are inconsistent on this.
I'm not entirely sure this change is correct for all architectures either.
Perhaps we should just over-allocate and not worry about it?
the StgDictObject's ffi_type member had the same name as its type. I
changed that to ffi_type_pointer. Feel free to change it to something else
more meaningful, just not ffi_type.
not be tracked by GC. This fixes 254 of test_generators' refleaks on my
machine, but I'm sure something else will make them come back :>
Not adding a separate test for this kind of cycle, since the existing
fib/m235 already test them in more extensive ways than any 'minimal' test
has been able to manage.
using a custom, nearly-identical macro. This probably changes how some of
these functions are compiled, which may result in fractionally slower (or
faster) execution. Considering the nature of traversal, visiting much of the
address space in unpredictable patterns, I'd argue the code readability and
maintainability is well worth it ;P
