Add PyFrozenSet_Check(), which was not needed before; The list of Py*Set_Check* macros seems to be complete now. Add missing NEWS entries about all this. ........ r60563 | amaury.forgeotdarc | 2008-02-04 00:14:32 +0100 (Mon, 04 Feb 2008) | 2 lines Nasty typo in setobject.h ........ r60564 | amaury.forgeotdarc | 2008-02-04 00:15:32 +0100 (Mon, 04 Feb 2008) | 3 lines Correct test_mailbox on win32: since the test sets a custom 'colon' attribute to the main mailbox, copy it to secondary mailbox instances. ........ r60565 | amaury.forgeotdarc | 2008-02-04 00:57:24 +0100 (Mon, 04 Feb 2008) | 2 lines Let test_socketserver pass on win32, which does not have AF_UNIX sockets. ........ r60566 | jeffrey.yasskin | 2008-02-04 02:04:35 +0100 (Mon, 04 Feb 2008) | 2 lines Make int() and long() fall back to __trunc__(). See issue 2002. ........ r60567 | christian.heimes | 2008-02-04 19:00:12 +0100 (Mon, 04 Feb 2008) | 3 lines Patch #1953 I implemented the function sys._compact_freelists() and C API functions PyInt_/PyFloat_CompactFreeList() to compact the pre-allocated blocks of ints and floats. They allow the user to reduce the memory usage of a Python process that deals with lots of numbers. The patch also renames sys._cleartypecache to sys._clear_type_cache ........
