871817 - Update Python in MozillaBuild to 2.7.5

Status: VERIFIED FIXED

(Firefox Build System :: MozillaBuild, task)

Description

[Myk Melez [:myk] [@mykmelez]]

Python 2.7.4 has a bug <http://bugs.python.org/issue17656> that causes the Firefox OS Simulator's build process to fail in MozillaBuild 1.7 with:

--------------------------------------------------------------------------------
Traceback (most recent call last):
   File "build/override-webapps.py", line 46, in <module>
   File "c:\mozilla-build\python\lib\zipfile.py", line 1024, in extract
     return self._extract_member(member, path, pwd)
   File "c:\mozilla-build\python\lib\zipfile.py", line 1057, in
_extract_member
     arcname = arcname.translate(table)
TypeError: character mapping must return integer, None or unicode
--------------------------------------------------------------------------------

Once Python ships 2.7.5, which Benjamin Peterson suggests they're going to do to address this issue <http://bugs.python.org/issue17656#msg186444>, it'd be very helpful for MozillaBuild to ship an update that includes the new version of Python, since the Simulator team uses MozillaBuild to build on Windows, and this bug prevents us from using MozillaBuild 1.7.

Bummer. In the meantime, you can just delete the python dir inside your mozilla-build install and install some other version of Python in there, MozillaBuild doesn't care what version it is.

Hopefully we can spin up a 1.7.1 prerelease build shortly.

Awesome, thanks!  Let me know when you do (or just cc: me on the relevant bug), and I'll test it in advance to make sure it resolves the problem with building the Simulator.

Wow, that took a lot longer than anticipated. Regardless, here's a build to test with.

Sorry for the insanely long delay on this. I promise it won't take this long in the future.

Yup, the Simulator build process works as expected with that version of MozillaBuild.  Thanks for the fix!
