add test for merge result when lines are inserted at the top of a file
Based on a patch by Omar Polo
fix histedit_no_op test which was failing randomly
A no-op replayed history ends up having exactly the same commit IDs if all commits are created at roughly the same moment in time. There are no content changes involved so if commit timestamps do not differ then commit hashes will be the same. In which case there is no fork in history for 'got histedit -l' to display, yet the test was always expecting a fork in history to be displayed. Update the test to take this issue into account. The test will now pass no matter which result is produced by the histedit operation. Problem found by Lucas who observed that this test was randomly failing. Patch also provided by Lucas.
ensure that old commits remain referenced after rebase and histedit
Create automatic "backup" references which ensure that objects from the pre-rebase or pre-histedit state remain in the repository. A new -l option for 'got rebase' and 'got histedit' lists old commits. This makes it easier to recover from botched rebase or histedit operations. Removal of such objects currently requires got ref -d and git-gc. This will be made more convenient in the future. testing and ok jrick
implicitly mark all files in work tree as up-to-date after rebase/histedit
This should always be correct, since rebase and histedit start out with a clean and single-base-commit worktree, and end up committing all changes across the entire work tree when they are successful. tested by jrick and myself
make 'got histedit' collapse folded add+delete operations into a no-op
If a merged commit wants to delete a locally added file, and this locally added file matches the content which was deleted in the commit being merged, we can go ahead with the deletion because there is no risk of data loss. fixes the histedit problem reported by jrick on freenode
add an xfail test for a histedit issue where a deleted file remains
If a previous commit introduces a new file, and it is folded into a commit that deletes the same file, the file still exists after the histedit. reported by jrick on freenode
add a -q option to tests for quiet output and use it for 'make regress'
Previous default output remains when test cases are run individually. ok tracey
prevent commits from being listed more than once in a histedit script
While merging a commit multiple times during a histedit operation could potentially make sense in some corner case, a commit appearing more than once in the script is more likely to happen accidentally. If desired, the same effect can still be achieved by running multiple histedit operations, or by using 'got cherrypick' while the histedit operation is paused for arbitrary editing.
fix histedit 'rebase commit ID mismatch' error when splitting a commit
Commit IDs on histedit's temporary branch can change arbitrarily because the user may create new commits on this branch while editing past commits. So there is no point in trying to verify these IDs like we do during rebase. Add a test case which demonstrates the problem.
