I use mercurial for my personal projects. I run mercurial-server. I wanted to have a hook on the server that would clone the repository so additional tasks could be performed against the contents of the repository without affecting the server’s repository.
I started by creating a hook script at /var/lib/mercurial-server/repos/somerepo/.hg/push-hook.sh
:
#!/bin/bash PUSH_COPY="/var/lib/mercurial-server/checkout-for-push/somerepo" if ! [ -d $PUSH_COPY ] ; then echo "CLONE: $PUSH_COPY" /usr/bin/hg clone /var/lib/mercurial-server/repos/somerepo $PUSH_COPY else echo "UPDATE: $PUSH_COPY" /usr/bin/hg pull -R $PUSH_COPY -v -u fi echo "do more work here..."
Then I added the following to /var/lib/mercurial-server/repos/somerepo/.hg/hgrc
:
[hooks] changegroup = /var/lib/mercurial-server/repos/somerepo/.hg/push-hook.sh
This got me to the point of being able to check out the server repository but updating it failed with the following message:
remote: UPDATE: /var/lib/mercurial-server/checkout-for-push/somerepo remote: pulling from /var/lib/mercurial-server/repos/somerepo remote: searching for changes remote: 2 changesets found remote: adding changesets remote: calling hook outgoing.aaaaa_servelog: mercurialserver.servelog.hook remote: transaction abort! remote: rollback completed remote: abort: outgoing.aaaaa_servelog hook is invalid (import of "mercurialserver.servelog" failed)
After a lot of digging and Google searches, I wasn’t coming up with any answers. One person mentioned that an environment variable may be set wrong, causing errors. Once I dumped the environment variables out, I unset each one at a time to see if any were causing problems. I ended up needing to add unset HGRCPATH
to the top of the hook script before any hg
commands run. So my push script now looks like:
#!/bin/bash unset HGRCPATH PUSH_COPY="/var/lib/mercurial-server/checkout-for-push/somerepo" if ! [ -d $PUSH_COPY ] ; then echo "CLONE: $PUSH_COPY" /usr/bin/hg clone /var/lib/mercurial-server/repos/somerepo $PUSH_COPY else echo "UPDATE: $PUSH_COPY" /usr/bin/hg pull -R $PUSH_COPY -v -u fi echo "do more work here..."
And the output of a push command now looks a lot better:
pushing to ssh://hg@hg.example.com/somerepo searching for changes remote: adding changesets remote: adding manifests remote: adding file changes remote: added 1 changesets with 1 changes to 1 files remote: UPDATE: /var/lib/mercurial-server/checkout-for-push/somerepo remote: pulling from /var/lib/mercurial-server/repos/somerepo remote: searching for changes remote: 3 changesets found remote: adding changesets remote: adding manifests remote: adding file changes remote: added 3 changesets with 3 changes to 2 files remote: resolving manifests ...
