The Camel 2.x branches are here:
The idea is to be able to apply bug fixes and backwards compatible improvements and new features to our Camel maintenance branches (for example 2.10.x and 2.9.x) while leaving NONE backwards compatible changes on the trunk. The idea is to give our users the best experience possible on any supported branch as long we have 100% backward compatibility on patch versions.
For all the changes in this category we have to be especially carefully to not break backwards compatibly. Again, the goal is to be 100% backward compatibility on patch versions. Take extra time to review and test your change. Even better, send a [HEADS UP] on the dev@ mailing list and ask for assistance/review.
It is preferred that the committer who applied the change to trunk also merge it back to the maintenance branches. He knows best whether this fix should go into the maintenance branche(s) or not and he can also make sure the WIKI pages are up to date. However, other people may also merge fixes back if they require it there. In that case, those people should pay extra attention to make sure the changes meet the above criteria.
I've set up svnmerge.py to track commits from the trunk to the 2.x branches.
1. You just committed a fix to the trunk in revision 123456 and think that it would be back ported to Camel 2.8.x users
2. Check out the branch
3. In camel-2.8.x directory, you can get a list of commits available from the trunk
4. Merge your commit by running
5. Resolve any conflicts in the merge
6. Commit it by running
7. If you have a JIRA associated with this fix, make sure it says fix for 2.8.x.
If you have trouble with the svnmerge.py file such as Claus Ibsen had, then he attached an older svnmerge.py file, to this wiki page that works.
If you look in:
there is a DoMerges.java file in there that you can compile and run from a fixes branch checkout.
It lists all the outstanding commits that haven't been reviewed, allows you to merge commits individually, block commits, show the diffs, etc.
To run the file do, from the directory with the branch.
You need svnmerge.py to be runnable from the command line.
There is a compiled .class of the DoMerges attached to this wiki page you can download. However its easy to compile
If you already use git-svn, you could consider using the great git merge capabilities.
Create a local branch from the remote tracking branch (e.g. camel-2.8.x)
or switch into the existing branch
To merge one revision (e.g. 1176050) into this branch, run
This will merge and commit the changes into your local git repository.
to push your local changes into the Apache SVN repository.
If you have a JIRA associated with this fix, make sure it says fix for 2.8.x.
