Merging (request for discussion and inclusion on the main page)
Merging issues can be made much easier to solve with the following instructions:
yum install meld
Then configure git to use meld for merging:
git config --global merge.tool meld
Then, when merge conflicts occur, it can be resolved in a very nice, graphical interface by using the command:
Working with branches
Currently we follow a merging-down strategy meaning fixes go in master and get merged down into f<X> and f<X-1> etc. However, this strategy can be confusing looking at the changelog of the spec file, e.g. when a rebuild happened in rawhide, which didn't take place in f<X>, but the changelog still has that entry on the f<X> branch. Of course, one could cherry pick a single commit, e.g. a version bump, down to a branch, but that would change the hashsum of the commit and hence "git branch --contains <HASH>" doesn't work anymore.
Alternatively, one could follow a workflow as described in gitworkflows(7), like many project incl. FFmpeg do, which would apply the version bump on the lowest branch and merging it up to master.
fedpkg switch-branch f25 git commit -m "version bump" fedpkg switch-branch master git merge
where the last step might include some conflict resolving.
