Added "Z" format_char to PyOS_ascii_formatd to support empty float presentation type. Renamed buf_size in PyOS_ascii_formatd to more accurately reflect it's meaning. Modified format.__float__ to use the new "Z" format as the default. Added test cases. ........ r61435 | eric.smith | 2008-03-17 13:14:29 +0100 (Mo, 17 Mär 2008) | 2 lines Reformated lines > 79 chars. Deleted unused macro ISXDIGIT. ........ r61436 | jeffrey.yasskin | 2008-03-17 15:40:53 +0100 (Mo, 17 Mär 2008) | 13 lines Allow Gnu gcc's to build python on OSX by removing -Wno-long-double, -no-cpp-precomp, and -mno-fused-madd from configure. * r22183 added -no-cpp-precomp, which http://gcc.gnu.org/ml/gcc/2005-12/msg00368.html claims hasn't been needed since gcc-3.1. * r25607 added -Wno-long-double to avoid a warning in Include/objimpl.h (issue 525481). The long double is still there, but OSX 10.4's gcc no longer warns about it. * r33666 fixed issue 775892 on OSX 10.3 by adding -mno-fused-madd, which changed the sign of some float 0s. Tim Peters said it wasn't a real issue anyway, and it no longer causes test failures. Fixes issue #1779871. ........ r61439 | martin.v.loewis | 2008-03-17 17:31:57 +0100 (Mo, 17 Mär 2008) | 2 lines Add Trent Nelson. ........ r61444 | travis.oliphant | 2008-03-17 18:36:12 +0100 (Mo, 17 Mär 2008) | 1 line Add necessary headers to back-port new buffer protocol to Python 2.6 ........ r61449 | gregory.p.smith | 2008-03-17 19:48:05 +0100 (Mo, 17 Mär 2008) | 8 lines Force zlib.crc32 and zlib.adler32 to return a signed integer on all platforms regardless of the native sizeof(long) used in the integer object. This somewhat odd behavior of returning a signed is maintained in 2.x for compatibility reasons of always returning an integer rather than a long object. Fixes Issue1202 for Python 2.6 ........ r61450 | neal.norwitz | 2008-03-17 20:02:45 +0100 (Mo, 17 Mär 2008) | 3 lines Use a buffer large enough to ensure we don't overrun, even if the value is outside the range we expect. ........ r61453 | steven.bethard | 2008-03-17 20:33:11 +0100 (Mo, 17 Mär 2008) | 1 line Document unicode.isnumeric() and unicode.isdecimal() (issue2326) ........ r61458 | neal.norwitz | 2008-03-17 21:22:43 +0100 (Mo, 17 Mär 2008) | 5 lines Issue 2321: reduce memory usage (increase the memory that is returned to the system) by using pymalloc for the data of unicode objects.

We still sleep at all to make it likely that all threads are active at the same time. ........ r61496 | jeffrey.yasskin | 2008-03-18 06:12:41 +0100 (Di, 18 Mär 2008) | 4 lines Speed up test_dict by about 10x by only checking selected dict literal sizes, instead of every integer from 0 to 400. Exhaustive testing wastes time without providing enough more assurance that the code is correct. ........ r61498 | neal.norwitz | 2008-03-18 06:20:29 +0100 (Di, 18 Mär 2008) | 1 line Try increasing the timeout to reduce the flakiness of this test. ........ r61503 | brett.cannon | 2008-03-18 06:43:04 +0100 (Di, 18 Mär 2008) | 2 lines Improve the error message for a test that failed on the S-390 Debian buildbot. ........ r61504 | jeffrey.yasskin | 2008-03-18 06:45:40 +0100 (Di, 18 Mär 2008) | 3 lines Add a -S/--slow flag to regrtest to have it print the 10 slowest tests with their times. ........ r61507 | neal.norwitz | 2008-03-18 07:03:46 +0100 (Di, 18 Mär 2008) | 1 line Add some info to the failure messages ........ r61509 | trent.nelson | 2008-03-18 08:02:12 +0100 (Di, 18 Mär 2008) | 1 line Issue 2286: bump up the stack size of the 64-bit debug python_d.exe to 2100000. The default value of 200000 causes a stack overflow at 1965 iterations of r_object() in marshal.c, 35 iterations before the 2000 limit enforced by MAX_MARSHAL_STACK_DEPTH. ........ r61510 | trent.nelson | 2008-03-18 08:32:47 +0100 (Di, 18 Mär 2008) | 5 lines The behaviour of winsound.Beep() seems to differ between different versions of Windows when there's either: a) no sound card entirely b) legacy beep driver has been disabled c) the legacy beep driver has been uninstalled Sometimes RuntimeErrors are raised, sometimes they're not. If _have_soundcard() returns False, don't expect winsound.Beep() to raise a RuntimeError, as this clearly isn't the case, as demonstrated by the various Win32 XP buildbots. ........ r61515 | martin.v.loewis | 2008-03-18 13:20:15 +0100 (Di, 18 Mär 2008) | 2 lines norwitz-amd64 (gentoo) has EREMOTEIO. ........ r61516 | martin.v.loewis | 2008-03-18 13:45:37 +0100 (Di, 18 Mär 2008) | 2 lines Add more Linux error codes. ........ r61517 | martin.v.loewis | 2008-03-18 14:05:03 +0100 (Di, 18 Mär 2008) | 2 lines Add WSA errors. ........ r61518 | martin.v.loewis | 2008-03-18 14:16:05 +0100 (Di, 18 Mär 2008) | 2 lines Note that the stderr output of the test is intentional. ........
