Re: Gecko 17 as the base for B2G v1

2012-09-04 Thread Alex Keybl
We'd discussed this, but due to current dev status and scheduling, drivers now feel that there's a good chance of needing to branch B2G's Gecko before it's on mozilla-release to limit risk to desktop/mobile, which would nullify any delays meant to keep B2G tied to the next ESR. In terms of long

No more egg-info directories in source directory

2012-09-04 Thread Gregory Szorc
I just landed a change to how the Python virtualenv is populated during configure. The short story is there are no more .egg-info/ directories created in the source directory as part of virtualenv population. These directories are no longer ignored by .hgignore and .gitignore, so the next time
