1010603 - Cleanup ignored *.pyc in the source directory with a clobber

Status: RESOLVED DUPLICATE of bug 1184696

(Firefox Build System :: General, enhancement)

Description

[Matthew N. [:MattN]]

It would be nice if a clobber would cleanup leftover *.pyc that may be leftover so it gets you back to a clean build environment. In bug 1008648, the build failed for users who had an source directory from 2011 as there were *.pyc files remaining in the source directory that were being used instead of the new version. Since *.pyc will be automatically recreated the next time the .py files are used, it seems pretty safe to me (though I'm no Python expert).

e.g.
hg st -i | grep "\.pyc$" | cut -f 2 -d " " | xargs rm

I would like this change. Sure, you can manually delete the files with "purge" or just find/rm, but it's not always obvious that you need to, especially for developers inexperienced with Python in complex build systems. If we made this change then changes that are likely to cause .pyc-related breakage could clobber.
