How to pull one commit at a time from a remote git repository?
- by Norman Ramsey
I'm trying to set up a darcs mirror of a git repository. I have something that works OK, but there's a significant problem: if I push a whole bunch of commits to the git repo, those commits get merged into a single darcs patchset. I really want to make sure each git commit gets set up as a single darcs patchset. I bet this is possible by doing some kind of git fetch followed by interrogation of the local copy of the remote branch, but my git fu is not up to the job.
Here's the (ksh) code I'm using now, more or less:
git pull -v # pulls all the commits from remote --- bad!
# gets information about only the last commit pulled -- bad!
author="$(git log HEAD^..HEAD --pretty=format:"%an <%ae>")"
logfile=$(mktemp)
git log HEAD^..HEAD --pretty=format:"%s%n%b%n" > $logfile
# add all new files to darcs and record a patchset. this part is OK
darcs add -q --umask=0002 -r .
darcs record -a -A "$author" --logfile="$logfile"
darcs push -a
rm -f $logfile
My idea is
Try git fetch to get local copy of the remote branch (not sure exactly what arguments are needed)
Somehow interrogate the local copy to get a hash for every commit since the last mirroring operation (I have no idea how to do this)
Loop through all the hashes, pulling just that commit and recording the associated patchset (I'm pretty sure I know how to do this if I get my hands on the hash)
I'd welcome either help fleshing out the scenario above or suggestions about something else I should try.
Ideas?
