In particular, fix extension module build failures when trying to use
32-bit-only installer Pythons on systems with Xcode 4 (currently
OS X 10.8, 10.7, and optionally 10.6).
* Backport 3.3.0 fixes to 3.2 branch (for release in 3.2.4)
* Since Xcode 4 removes ppc support, extension module builds now
check for ppc compiler support and by default remove ppc and
ppc64 archs when they are not available.
* Extension module builds now revert to using system installed
headers and libs (/usr and /System/Library) if the SDK used
to build the interpreter is not installed or has moved.
* Try to avoid building extension modules with deprecated
and problematic Apple llvm-gcc compiler. If original compiler
is not available, use clang instead by default.
There was a window between the write and the chmod where the user’s
password would be exposed, depending on default permissions. Philip
Jenvey’s patch fixes it.
These files are created by some NFS clients a file is edited and removed
concurrently (see added link in doc for more info). If such a file is
removed between distutils calls listdir and copy, it will get confused.
Other special files are ignored in sdist (namely VCS directories), but
this has to be filtered out earlier.
python executable
The __os_install_macro defines some post-processing activities during an rpm
build; one of the scripts it calls is brp-python-bytecompile, which can take
an argument: the python executable with which to byte-compile .py files in the
package payload.
In some older versions of rpm (e.g. in RHEL 6), this invocation doesn't pass
in an argument, and brp-python-bytecompile defaults to using /usr/bin/python,
which can lead to the .py files being byte-compiled for the wrong version of
python. This has been fixed in later versions of rpm by passing in
%{__python} as an argument to brp-python-bytecompile.
Workaround this by detecting if __os_install_post has a 0-argument invocation
of brp-python-bytecompile, and if so generating an equivalent macro that has
the argument, and explicitly provide the new definition within the specfile.
These regex changes fix a number of issues for distutils on Windows:
- #6884: impossible to include a file starting with 'build'
- #9691 and #14004: sdist includes too many files
- #13193: test_filelist failures
This commit replaces the incorrect changes done in 0a94e2f807c7 and
90b30d62caf2 to fix#13193; we were too eager to fix the test failures
and I did not study the code enough before greenlighting patches. This
time we have unit tests from the problems reported by users to be sure
we have the right fix.

The code used to call os.path.join to build a regex but without escaping
the backslash, which lead to test failures on Windows. Antoine Pitrou
fixed it in 0a94e2f807c7 by enhancing the code to accept both / and \,
with proper escaping, but in my opinion this goes against the distutils
feature freeze, hence this change.
Distutils-based packages with C extension modules may fail because
Apple has removed gcc-4.2, the version used to build python.org
64-bit/32-bit Pythons. If the user does not explicitly override
the default C compiler by setting the CC environment variable,
Distutils will now attempt to compile extension modules with clang
if gcc-4.2 is required but not found. Also as a convenience, if
the user does explicitly set CC, substitute its value as the default
compiler in the Distutils LDSHARED configuration variable for OS X.
(Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
SDK, neither of which are available in Xcode 4. This change does not
attempt to override settings to support their use with Xcode 4.)
Bug reported by Hartmut Goebel and patch contributed by Carl Robben.
Carl tested the fix and we have a buildbot with rpm installed, so I’m
committing even though I could not run this test (but I do understand
the changed code :)
- Actually check the contents of the file created by bdist_dumb.
- Don’t use “RECORD” as filename for non-PEP 376 record file
- Don’t start method name with “_test”, it smells like a disabled test
method instead of an helper method
- Fix some idioms (assertIn, addCleanup)
