stg repair [OPTIONS]

If a branch with a StGit stack is modified with certain git commands such as git-commit(1), git-pull(1), git-merge(1), or git-rebase(1), the StGit stack metadata will become inconsistent with the branch state. There are a few options for resolving this kind of situation:

1. Use stg-undo(1) to undo the effect of the git commands. Or similarly use stg-reset(1) to reset the stack/branch to any previous stack state.

2. Use stg repair. This will repair the StGit stack metadata to accommodate the modifications to the branch made by the git commands. Specifically, it will do the following:

   • If regular git commits were made on top of the stack of StGit patches (i.e. by using plain git commit), stg repair will convert those commits to StGit patches, preserving their content.
   • However, merge commits cannot become patches. So if a merge was committed on top of the stack, stg repair will mark all patches below the merge commit as unapplied, since they are no longer reachable. An alternative when this is not the desired behavior is to use stg undo to first get rid of the offending merge and then run stg repair again.
   • The applied patches are supposed to be precisely those that are reachable from the branch head. If, for example, git-reset(1) was used to move the head, some applied patches may no longer be reachable and some unapplied patches may have become reachable. In this case, stg repair will correct the applied/unapplied state of such patches.

stg repair will repair these inconsistencies reliably, so there are valid workflows where git commands are used followed by stg repair. For example, new patches can be created by first making commits with a graphical commit tool and then running stg repair to convert those commits into patches.
