Test rebasing of merges with ancestors of the rebase destination - a situation
|
|
that often happens when trying to recover from repeated merging with a mainline
|
|
branch.
|
|
|
|
The test case creates a dev branch that contains a couple of merges from the
|
|
default branch. When rebasing to the default branch, these merges would be
|
|
merges with ancestors on the same branch. The merges _could_ contain some
|
|
interesting conflict resolutions or additional changes in the merge commit, but
|
|
that is mixed up with the actual merge stuff and there is in general no way to
|
|
separate them.
|
|
|
|
Note: The dev branch contains _no_ changes to f-default. It might be unclear
|
|
how rebasing of ancestor merges should be handled, but the current behavior
|
|
with spurious prompts for conflicts in files that didn't change seems very
|
|
wrong.
|
|
|
|
The branches are emulated using commit messages.
