* Backport rev 51262 from trunk -- squashes a compiler warning on WindowsTim Peters2006-10-091-2/+2
| | | | | | | | | | about truly wrong code. Checkin comment from 51262: Can't return NULL from a void function. If there is a memory error, about the best we can do is call PyErr_WriteUnraisable and go on. We won't be able to do the call below either, so verify delstr is valid.
* Backport of the pieces of trunk rev 46589 relevant toTim Peters2006-10-091-1/+31
| | | | | | | | | | | | | fixing an unlikely crash bug in dict resizing, SF bug 1456209. The rest of rev 46589 changes whether Python suppresses exceptions during some dict-related comparisons. While I think that's a good idea, it does change visible behavior at times, and there was already some complaining about that on the trunk. Not a good idea for backporting. The part of 46589 checked in here can at worst stop segfaults, and I doubt anyone will gripe about that ;-)
* [Partial backport of r45947 | neal.norwitz]Andrew M. Kuchling2006-10-091-2/+3
| | | | | | | | | | Fix problems found by Coverity. longobject.c: also fix an ssize_t problem <a> could have been NULL, so hoist the size calc to not use <a>. [The ssize_t change isn't needed for 2.4. The other changes in this revision are to modules not present in 2.4. --amk]
* [Backport r42951 | guido.van.rossum]Andrew M. Kuchling2006-10-091-2/+6
| | | | | | | | | Fix three nits found by Coverity, adding null checks and comments. [This commit only makes two changes. One change in the original patch is just adding a comment, and another adds a 'base != NULL' check to silence Coverity, but a comment adds that that base is never going to be NULL. I didn't backport that change. --amk]
* [Backport r43695 | neal.norwitz]Andrew M. Kuchling2006-10-061-8/+5
| | | | | | Remove dead code (reported by HP compiler). Can probably be backported if anyone cares.
* [Backport r50679 | neal.norwitz. This is the last Klocwork bug to beAndrew M. Kuchling2006-10-051-7/+7
| | | | | | | | | | | | backported.] Use sizeof(buffer) instead of duplicating the constants to ensure they won't be wrong. The real change is to pass (bufsz - 1) to PyOS_ascii_formatd and 1 to strncat. strncat copies n+1 bytes from src (not dest). Reported by Klocwork #58.
* [Backport r50681 | neal.norwitz]Andrew M. Kuchling2006-10-051-2/+2
| | | | | | | PyFunction_SetDefaults() is documented as taking None or a tuple. A NULL would crash the PyTuple_Check(). Now make NULL return a SystemError. Reported by Klocwork #73.
* [Backport r51246 | neal.norwitz]Andrew M. Kuchling2006-10-051-30/+110
| | | | | | | | | | | | | Handle a whole lot of failures from PyString_FromInternedString(). Should fix most of Klocwork 234-272. [Backport r51400 | neal.norwitz] Move initialization of interned strings to before allocating the object so we don't leak op. (Fixes an earlier patch to this code) Klockwork #350
* [Partial backport of r51218 | neal.norwitz -- the changes to ast.c, symtable.c,Andrew M. Kuchling2006-10-051-0/+4
| | | | | | | | | and _elementtree.c weren't applicable] Klocwork made another run and found a bunch more problems. This is the first batch of fixes that should be easy to verify based on context. This fixes problem numbers: 220 (ast), 323-324 (symtable), 321-322 (structseq), 215 (array), 210 (hotshot), 182 (codecs), 209 (etree).
* [Backport r50743 | neal.norwitz]Andrew M. Kuchling2006-10-052-0/+5
| | | | | Handle allocation failures gracefully. Found with failmalloc. Many (all?) of these could be backported.
* [Backport r51248 | neal.norwitz]Andrew M. Kuchling2006-10-051-1/+4
| | | | | | | Fix segfault when doing string formatting on subclasses of long if __oct__, __hex__ don't return a string. Klocwork 308
* A review of overflow-detecting code in the 2.4 branch.Armin Rigo2006-10-047-37/+70
| | | | | | | | | | | | * 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.
* Fix integer negation and absolute value to not relyMartin v. Löwis2006-10-041-4/+3
| | | | on undefined behaviour of the C compiler anymore.
* [Backport r51230 | neal.norwitz]Andrew M. Kuchling2006-10-031-2/+6
| | | | | | | Check return of PyMem_MALLOC (garbage) is non-NULL. Check seq in both portions of if/else. Klocwork #289-290.
* [Backport r50779 | neal.norwitz]Andrew M. Kuchling2006-10-031-1/+2
| | | | | | | | Move the initialization of size_a down below the check for a being NULL. Reported by Klocwork #106. [Slight change required: in 2.5 Py_ssize_t is used, but 2.4 uses int.]
* [Backport r50683 | neal.norwitz]Andrew M. Kuchling2006-10-031-3/+6
| | | | | | | Stop INCREFing name, then checking if it's NULL. name (f_name) should never be NULL so assert it. Fix one place where we could have passed NULL. Reported by Klocwork #66.
* [Backport r50680 | neal.norwitz]Andrew M. Kuchling2006-10-031-3/+3
| | | | Handle a NULL name properly.
* [Backport rev. 42545 by georg.brandl]Andrew M. Kuchling2006-10-031-0/+4
| | | | Make staticmethod and classmethod complain about keyword args.
* [Backport rev. 51669 by brett.cannon]Andrew M. Kuchling2006-10-031-1/+1
| | | | | | Make sure memory is properly cleaned up in file_init. Backport candidate.
* [Backport rev. 47171 by neal.norwitz]Andrew M. Kuchling2006-10-031-0/+2
| | | | Another problem reported by Coverity. Backport candidate.
* Patch #1567691: super() and new.instancemethod() now don't acceptGeorg Brandl2006-09-302-0/+4
| | | | | | keyword arguments any more (previously they accepted them, but didn't use them). (backport from rev. 52058)
* [Backport rev. 46878 by neal.norwitz]Andrew M. Kuchling2006-09-291-1/+3
| | | | | Don't leak the list object if there's an error allocating the item storage. Backport candidate.
* [Backport rev. 39743 by lemburg]Andrew M. Kuchling2006-09-291-8/+16
| | | | | | Bug fix for [ 1331062 ] utf 7 codec broken. Backport candidate.
* Merge rev 51711 from the 2.5 branch.Tim Peters2006-09-051-2/+8
| | | | | | i_divmod(): As discussed on Python-Dev, changed the overflow checking to live happily with recent gcc optimizations that assume signed integer arithmetic never overflows.
* Backport rev 51448:Georg Brandl2006-08-221-12/+25
| | | | | - Patch #1541585: fix buffer overrun when performing repr() on a unicode string in a build with wide unicode (UCS-4) support.

* after discussions with perky, reverted fix for Bug #1379994: BuiltinAnthony Baxter2006-03-281-3/+3
| | | | | | | | | unicode_escape and raw_unicode_escape codec now encodes backslash correctly. This caused another issue for unicode repr strings being double-escaped (SF Bug #1459029). Correct fix will be in 2.5, but is too risky for 2.4.3. Added a testcase for #1459029.

* Backport 43022:Neal Norwitz2006-03-141-5/+7
| | | | | | | | | | | | Fix and test (manually w/xx module) passing NULLs to PyObject_Str() and 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.

* Backport:Neal Norwitz2006-01-101-16/+21
| | | | | | | | | | | | | | | | - Patch #1400181, fix unicode string formatting to not use the locale. This is how string objects work. u'%f' could use , instead of . for the decimal point. Now both strings and unicode always use periods. This is the code that would break: import locale locale.setlocale(locale.LC_NUMERIC, 'de_DE') u'%.1f' % 1.0 assert '1.0' == u'%.1f' % 1.0 I couldn't create a test case which fails, but this fixes the problem. (tested in interpreter and reported fixed by others)
