Hi all,
Right now, it's impossible to merge from lp:gcc/4.7 to
lp:gcc-linaro/4.7. This is due to a BZR bug of some kind, so hopefully
we won't have to work around it for too much longer.
According to the nice folks at #bzr, here's how to do the same merge
manually:
bzr branch lp:gcc-linaro/4.7
cd gcc-linaro
bzr log | less
# find the last merge revision (it should be clear from the message)
# grab the *SVN* revision number
bzr log --show-ids lp:gcc/4.7 | less
# search for the *SVN* revision number
# (it should appear on the end of a "revision-id" line, not "parent")
# grab the corresponding *BZR* revision number ("revno")
bzr diff -r <bzr-revno> lp:gcc/4.7 > ../patch
patch -p0 -i ../patch
# resolve conflicts, rejected hunks, etc.
bzr add --file-ids-from lp:gcc/4.7
# if it's doing the right thing you'll get messages like:
# "adding <file> w/ file id from <file>"
# if it just says "adding file" then you got something wrong
# edit Changelog.linaro, as usual
bzr ci
bzr push lp:~.........gcc-linaro/merge-from....
After all that, a future "bzr merge" should just work (once the bug has
been fixed).
Anyway, I doubt there's anybody else needs to know this: I've just
posted it in case I get hit by a bus before next month.
Andrew
