37f694f21b No functional change. Add comment and assert to describe why there cannot be overflow which was reported by Klocwork. Discussed on python-dev 2006-07-27 04:04:50 +00:00

55b0a0eb0d [Bug #1471938] Fix build problem on Solaris 8 by conditionalizing the use of mvwgetnstr(); it was conditionalized a few lines below. Fix from Paul Eggert. I also tried out the STRICT_SYSV_CURSES case and am therefore removing the 'untested' comment. 2006-07-26 17:16:52 +00:00

5f135787ec Part of bug #1523610: fix miscalculation of buffer length. 
Also add a guard against NULL in converttuple and add a test case
(that previously would have crashed).

dce937f32c Ensure we don't write beyond errText. I think I got this right, but 
it definitely could use some review to ensure I'm not off by one
and there's no possible overflow/wrap-around of bytes_left.
Reported by Klocwork #1.

Fix a problem if there is a failure allocating self->db.
Found with failmalloc.

93f2ca1f85 Check the allocation of b_objects and return if there was a failure. 
Also fix a few memory leaks in other failure scenarios.

It seems that if b_objects == Py_None, we will have an extra ref to
b_objects.  Add XXX comment so hopefully someone documents why the
else isn't necessary or adds it in.

100a4e944b Make sure the _ctypes extension can be compiled when WITH_THREAD is 
not defined on Windows, even if that configuration is probably not
supported at all.

caebe22038 Fix bug #1520914. Starting in 2.4, time.strftime() began to check the bounds 
of values in the time tuple passed in.  Unfortunately people came to rely on
undocumented behaviour of setting unneeded values to 0, regardless of if it was
within the valid range.  Now those values force the value internally to the
minimum value when 0 is passed in.

93ab5fa191 #1494314: Fix a regression with high-numbered sockets in 2.4.3. This

24a0f41d83 - back out Expat change; the final fix to Expat will be different 
- change the pyexpat wrapper to not be so sensitive to this detail of the
  Expat implementation (the ex-crasher test still passes)

b4a6a566ff Sync the darwin/x86 port libffi with the copy in PyObjC. This fixes a number 
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).

74c3ea0a0f Fix build problems with the platform SDK on windows. It is not sufficient to test for the C compiler version when determining if we have the secure CRT from microsoft. Must test with an undocumented macro, __STDC_SECURE_LIB__ too. 2006-07-03 14:59:05 +00:00

f780be4239 Add a new function uses_seh() to the _ctypes extension module. This 
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.

638f7addf3 Fixes so that _ctypes can be compiled with the MingW compiler. 
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.

6ffe499397 SF bug #1296433 (Expat bug #1515266): Unchecked calls to character data 
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.

fe7d0c3bc6 Speculative checkin (requires approval of Gerhard Haering) 
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.
