[TODO: make the migration tool fix up gitweb and daemon control also...]
Migrating from gitosis to gitolite is pretty easy, because the basic design is the same.
Here's how we migrated my work repos:
login as the git
user on the server, and get a bash shell prompt
disable gitosis by renaming /usr/bin/gitosis-serve
to something
else. This will prevent users from pushing anything while you do the
backup, migration, etc.
edit ~/.ssh/authorized_keys
and carefully remove all the lines
containing "gitosis-serve", as well as the marker line that says
"auto-generated by gitosis, DO NOT REMOVE", then save the file. If the
file did not have any other keys and is now empty, don't worry -- save it
anyway because gitolite expects the file to be present (even if it is
empty).
For added safety, delete the post-update hook that gitosis-admin installed
rm ~/repositories/gitosis-admin.git/hooks/post-update
or at least rename it to .sample
like all the other hooks hanging
around, or edit it and comment out the line that calls gitosis-run-hook
post-update
.
If you do not do this, an accidental push to the gitosis-admin repo will
mess up your ~/.ssh/authorized_keys
file
take a backup of the ~/repositories
directory
Now, log off the server and get back to the client:
follow instructions to install gitolite; see the install document.
Make sure that you don't change the default path for $REPO_BASE
if
you edit the config file!
This will give you a gitolite config that has the required entries for the "gitolite-admin" repo.
convert your gitosis config file and append it to your gitolite config
file. Substitute the path for your gitosis-admin clone in $GSAC
below,
and similarly the path for your gito*lite*-admin clone in $GLAC
src/gl-conf-convert < $GSAC/gitosis.conf >> $GLAC/gitolite.conf
Be sure to check the file to make sure it converted correctly
copy the keys from gitosis's keydir (same meanings for GSAC and GLAC)
cp $GSAC/keydir/* $GLAC/keydir
Important: expand any multi-key files you may have. Here's an explanation of what multi-keys are, how gitosis does them and how gitolite does it differently.
You can split the keys manually, or use the following code (just copy-paste it into your xterm after "cd"-ing to your gitolite-admin repo clone):
wc -l keydir/*.pub | grep -v total | grep -v -w 1 | while read a b
do
i=1
cat $b|while read l
do
echo "$l" > ${b%.pub}@$i.pub
(( i++ ))
done
mv $b $b.done
done
This will split each multi-key file (say "sitaram.pub") into individual files called "sitaram@1.pub", "sitaram@2.pub", etc., and rename the original to "sitaram.pub.done" so gitolite won't pick it up.
At this point you can rename the split parts more appropriately, like "sitaram@laptop.pub" and "sitaram@desktop.pub" or whatever. Please check the files to make sure this worked properly
