758718 - Move default.xml generation into b2g build system

Status: RESOLVED FIXED

(Firefox OS Graveyard :: General, defect)

Description

[Jonathan Griffin (:jgriffin)]

The QA builds that are produced include a default.xml which specifies all the commits used to generate the build, and which can be used to reproduce the build exactly.

We should move this functionality into the B2G build system, so that such a default.xml is generated for every build and installed in the system.img.

Currently, the script that does this is at

https://github.com/jonallengriffin/b2gautomation/blob/master/b2gautomation/make_template_manifest.py

It uses a git module that isn't part of the Python stdlib, so we should probably rewrite this just to shell out to git.

Should be fixed AIUI.

Yup, it is!

I added an 'add-revision.py' script that does the leg-work:
  https://github.com/mozilla-b2g/gonk-misc/blob/master/add-revision.py

And hooked it into the build system:
  https://github.com/mozilla-b2g/gonk-misc/blob/master/Android.mk#L60

The result is a file that is installed onto the devices at '/system/sources.xml' that contains the sha-1 commit id for each repository in the revision attribute for each project in the xml.  If the commit is tagged, the tag appears as a comment.  One reason for this is that repo doesn't like to have revision attributes set to tag names.  Branches and commit ids work.
