* Avoid potential for undefined variable 'startinpos' in PyUnicode_DecodeUTF7().Guido van Rossum2009-03-051-2/+3
| | | | See issue #5389.
* Security patches from Apple: prevent int overflow when allocating memoryNeal Norwitz2008-07-311-11/+40

* #2242: utf7 decoding crashes on bogus input on some Windows/MSVC versionsAntoine Pitrou2008-07-251-1/+1

* #1477: ur'\U0010FFFF' used to raise in narrow unicode builds.Amaury Forgeot d'Arc2008-03-241-4/+42
| | | | | | | Corrected the raw-unicode-escape codec to use UTF-16 surrogates in this case, like the unicode-escape codec does. Backport of r61793 and r61853
* Backport r61458:Neal Norwitz2008-03-181-11/+15
| | | | | Issue 2321: reduce memory usage (increase the memory that is returned to the system) by using pymalloc for the data of unicode objects.
* Fix the overflows in expandtabs(). "This time for sure!"Guido van Rossum2008-03-111-25/+33
| | | | (Exploit at request.)
* Backport r58709 from trunk:Georg Brandl2007-11-021-3/+6
| | | | | | | | | Backport fixes for the code that decodes octal escapes (and for PyString also hex escapes) -- this was reaching beyond the end of the input string buffer, even though it is not supposed to be \0-terminated. This has no visible effect but is clearly the correct thing to do. (In 3.0 it had a visible effect after removing ob_sstate from PyString.) Also fixes #1098.
* Bug #1763149: use proper slice syntax in docstring.Georg Brandl2007-07-291-2/+2
| | | | (backport)
* Patch #1673759: add a missing overflow check when formatting floatsGeorg Brandl2007-07-121-1/+2
| | | | | with %G. (backport from rev. 56298)
* Backport 55874:Neal Norwitz2007-06-111-2/+8
| | | | | Fix a bug when there was a newline in the string expandtabs was called on. This also catches another condition that can overflow.
* Prevent expandtabs() on string and unicode objects from causing a segfault whenNeal Norwitz2007-06-091-3/+14
| | | | | | | a large width is passed on 32-bit platforms. Found by Google. It would be good for people to review this especially carefully and verify I don't have an off by one error and there is no other way to cause overflow.
* Forward-port of r52136: a review of overflow-detecting code.Armin Rigo2006-10-041-2/+5
| | | | | | | | | | | | | | | | | | | | | | | * unified the way intobject, longobject and mystrtoul handle values around -sys.maxint-1. * in general, trying to entierely avoid overflows in any computation involving signed ints or longs is extremely involved. Fixed a few simple cases where a compiler might be too clever (but that's all guesswork). * more overflow checks against bad data in marshal.c. * 2.5 specific: fixed a number of places that were still confusing int and Py_ssize_t. Some of them could potentially have caused "real-world" breakage. * list.pop(x): fixing overflow issues on x was messy. I just reverted to PyArg_ParseTuple("n"), which does the right thing. (An obscure test was trying to give a Decimal to list.pop()... doesn't make sense any more IMHO) * trying to write a few tests...
* Fix str.rpartition(sep) when sep is not found in str.Neal Norwitz2006-09-051-2/+2
| | | | Partially from SF patch #1551339, but also taken from head.
* - Patch #1541585: fix buffer overrun when performing repr() onNeal Norwitz2006-08-211-12/+25
| | | | | | a unicode string in a build with wide unicode (UCS-4) support. I will forward port to 2.6. Can someone backport to 2.4?
* Correct an accidentally removed previous patch.Marc-André Lemburg2006-08-141-5/+2
|
* Slightly revised version of patch #1538956:Marc-André Lemburg2006-08-141-4/+83
| | | | | | | | | | Replace UnicodeDecodeErrors raised during == and != compares of Unicode and other objects with a new UnicodeWarning. All other comparisons continue to raise exceptions. Exceptions other than UnicodeDecodeErrors are also left untouched.
* Patch #1538606, Patch to fix __index__() clipping.Neal Norwitz2006-08-121-5/+2
| | | | | | | I modified this patch some by fixing style, some error checking, and adding XXX comments. This patch requires review and some changes are to be expected. I'm checking in now to get the greatest possible review and establish a baseline for moving forward. I don't want this to hold up release if possible.
* Handle allocation failures gracefully. Found with failmalloc.Neal Norwitz2006-07-211-0/+3
| | | | Many (all?) of these could be backported.

| | | | | | | | | | | | | | results in a 2.5x speedup on the stringbench count tests, and a 20x (!) speedup on the stringbench search/find/contains test, compared to 2.5a2. for more on the algorithm, see: http://effbot.org/zone/stringlib.htm if you get weird results, you can disable the new algoritm by undefining USE_FAST in Objects/unicodeobject.c. enjoy /F
