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 :)
* Use str.startswith(tuple): I didn't know this Python feature, Python rocks!
* Replace sometimes sys.platform.startswith('linux') with
sys.platform == 'linux'
* sys.platform doesn't contain the major version on Cygwin on Mac OS X
(it's just 'cygwin' and 'darwin')
The changed behavior of sdist in 3.1 broke packaging for projects that
wanted to use a manually-maintained MANIFEST file (instead of having a
MANIFEST.in template and letting distutils generate the MANIFEST).
The fixes that were committed for #8688 (76643c286b9f by Tarek and
d54da9248ed9 by me) did not fix all issues exposed in the bug report,
and also added one problem: the MANIFEST file format gained comments,
but the read_manifest method was not updated to handle (i.e. ignore)
them. This changeset should fix everything; the tests have been
expanded and I successfully tested the 2.7 version with Mercurial, which
suffered from this regression.
I have grouped the versionchanged directives for these bugs in one place
and added micro version numbers to help users know the quirks of the
exact version they’re using.
Initial report, thorough diagnosis and patch by John Dennis, further
work on the patch by Stephen Thorne, and a few edits and additions by
me.
build_scripts command of packaging now handles correctly non-ASCII path (path
to the Python executable). Open and write the script in binary mode, but ensure
that the shebang is decodable from UTF-8 and from the encoding of the script.
