python3.11/00157-uid-gid-overflows.patch
David Malcolm 1c94c1ae4e 3.3.0-0.1.b1: 3.2 -> 3.3
* Fri Jul 20 2012 David Malcolm <dmalcolm@redhat.com> - 3.3.0-0.1.b1
- 3.2 -> 3.3: https://fedoraproject.org/wiki/Features/Python_3.3
- 3.3.0b1: refresh patches 3, 55, 102, 111, 113, 114, 134, 157; drop upstream
patch 147; regenenerate autotools patch; drop "--with-wide-unicode" from
configure (PEP 393); "plat-linux2" -> "plat-linux" (upstream issue 12326);
"bz2" -> "_bz2" and "crypt" -> "_crypt"; egg-info files are no longer shipped
for stdlib (upstream issues 10645 and 12218); email/test moved to
test/test_email; add /usr/bin/pyvenv[-3.3] and venv module (PEP 405); add
_decimal and _lzma modules; make collections modules explicit in payload again
(upstream issue 11085); add _testbuffer module to tests subpackage (added in
upstream commit 3f9b3b6f7ff0)
