Media/WebRTC/Legacy Updating Process

Process: rough, can use fleshing out

• Get a copy of the stable branch from SVN:
  • cd somewhere; svn checkout http://webrtc.googlecode.com/svn/branches/3.50
• rm -rf media/webrtc/trunk/webrtc
• cp -r somewhere/3.50/webrtc media/webrtc/trunk
• copy over any files in media/webrtc/trunk that are needed (few if any - DEPS, OWNERS, etc)
• hg addremove --similarity 70 --dry-run media/webrtc/trunk/webrtc 2>&1 >/tmp/addremove.out
• look for any false positives on renames and fix them (perhaps by adding them to an --exclude list when doing the real addremove\
  • near-empty files often result in false renames (null_transport.h, run_tests.cc, etc)
  • For 3.50, I had to use "--exclude media/webrtc/trunk/webrtc/test/run_tests.cc --exclude media/webrtc/trunk/webrtc/test/run_loop.cc --exclude media/webrtc/trunk/webrtc/video_engine/test/common/run_loop.cc --exclude media/webrtc/trunk/webrtc/video_engine/test/common/run_tests.cc" (not critical but reduces confusion)
• look for any false negatives (typically fiddle the '70') or correct by hand after - less critical
• hg revert files removed from media/webrtc/trunk/webrtc/modules/video_capture/windows/
  • do this before the real addremove! (can be undone later if needed)
• hg addremove --exclude <whatever> --similarity 70 media/webrtc/trunk/webrtc 2>&1 >/tmp/addremove.out
  • or you can --exclude the directory if there are no renames, adds or removals there
  • These are files we added to avoid including/using DirectShow/etc files from Microsoft examples
