Merging changes from Mercurial to Subversion during build

Jan Swaelens1

Hello,

We are playing with the idea to move our trunk svn to a mercurial repository, but we would still like to maintain our subversion trunk branch.

Since there have been quite some changes in the 'automatic merge' functionality of Bamboo I wanted to ask if this would be possible, without too much 'hassle' (read as: additional work).

Could we configure Bamboo to merge the changes made to the mercurial branch to the svn one when a build is made (triggered by a poll of the mercurial branch)?

thanks!

That's quite a challenge there. While I'm certain that Bamboo 'out-of-the-box' doesn't do what you need, I believe the proper solution here would be to plug into your central hg repository with a pre-push hook (or how they are called, you know - the hooks that get triggered whenever a new commit is pushed to your central repository in Mercurial) in such a way, that they will try to commit and sync with your svn repository, and if it fail - reject the hg push. That way the automatic merges from Bamboo won't push successfully if the changeset failed to be committed to the svn repo.

Though, I don't know if there is out-of-the-box solution for transforming arbitrary hg commit into svn commit...
