python3.12/python-3.2a1-systemtap.patch
David Malcolm 7eb10c8dbe 3.2a1
* Sat Aug 21 2010 David Malcolm <dmalcolm@redhat.com> - 3.2-0.0.a1
- 3.2a1; add alphatag
- rework %%files in the light of PEP 3147 (__pycache__)
- drop our configuration patch to Setup.dist (patch 0): setup.py should do a
better job of things, and the %%files explicitly lists our modules (r82746
appears to break the old way of doing things).  This leads to various modules
changing from "foomodule.so" to "foo.so".  It also leads to the optimized build
dropping the _sha1, _sha256 and _sha512 modules, but these are provided by
_hashlib; _weakref becomes a builtin module; xxsubtype goes away (it's only for
testing/devel purposes)
- fixup patches 3, 4, 6, 8, 102, 103, 105, 111 for the rebase
- remove upstream patches: 7 (system expat), 106, 107, 108 (audioop reformat
plus CVE-2010-1634 and CVE-2010-2089), 109 (CVE-2008-5983)
- add machinery for rebuilding "configure" and friends, using the correct
version of autoconf (patch 300)
- patch the debug build's usage of COUNT_ALLOCS to be less verbose (patch 125)
- "modulator" was removed upstream
- drop "-b" from patch applications affecting .py files to avoid littering the
installation tree
