Apply this to all the ABC collections as well as the class of os.environ which inherits from an ABC collection. ................ r56013 | neal.norwitz | 2007-06-17 19:56:31 -0700 (Sun, 17 Jun 2007) | 4 lines This should make it a little easier when adding new collections which use ABCs. The new subclass won't need to be listed in regrtest. It will be even better when Guido adds weakrefs. :-) ................ r56014 | martin.v.loewis | 2007-06-17 20:15:51 -0700 (Sun, 17 Jun 2007) | 1 line Drop inline, as it's not support by VS 2003. ................ r56015 | martin.v.loewis | 2007-06-17 20:17:19 -0700 (Sun, 17 Jun 2007) | 1 line Expect long objects for DWORD values. ................ r56016 | martin.v.loewis | 2007-06-17 20:18:01 -0700 (Sun, 17 Jun 2007) | 1 line Drop modules that have been deleted. ................ r56017 | martin.v.loewis | 2007-06-17 20:18:55 -0700 (Sun, 17 Jun 2007) | 1 line Bump DLL version number to 30. ................ r56018 | neal.norwitz | 2007-06-17 20:55:43 -0700 (Sun, 17 Jun 2007) | 62 lines Merged revisions 55951-56013 via svnmerge from svn+ssh://pythondev@svn.python.org/python/trunk ........ r55956 | thomas.heller | 2007-06-13 00:07:03 -0700 (Wed, 13 Jun 2007) | 2 lines Do not hardcode the buildbot's directory name. ........ r55957 | thomas.heller | 2007-06-13 00:07:41 -0700 (Wed, 13 Jun 2007) | 2 lines Notes about building tcl/tk for windows/AMD64. ........ r55958 | thomas.heller | 2007-06-13 00:54:57 -0700 (Wed, 13 Jun 2007) | 2 lines Build bzip2. ........ r55962 | walter.doerwald | 2007-06-13 09:57:12 -0700 (Wed, 13 Jun 2007) | 8 lines Add T_PYSSIZET in structmember.h: This can be used for Py_ssize_t members. Simplify the implementation of UnicodeError objects: start and end attributes are now stored directly as Py_ssize_t members, which simplifies various get and set functions. ........ r55975 | martin.v.loewis | 2007-06-14 13:46:25 -0700 (Thu, 14 Jun 2007) | 3 lines Patch #1734014: Use _I64_MAX instead of LLONG_MAX.
