* |
|
* The commits given by the two refs are merged, producing one of the following |
|
* outcomes: |
|
* |
|
* 1. The merge trivially results in an existing commit (e.g. fast-forward or |
|
* already-up-to-date). 'local_tree' is untouched, the OID of the result |
|
* is written into 'result_oid' and 0 is returned. |
|
* 2. The merge successfully completes, producing a merge commit. local_tree |
|
* contains the updated notes tree, the OID of the resulting commit is |
|
* written into 'result_oid', and 1 is returned. |
|
* 3. The merge results in conflicts. This is similar to #2 in that the |
|
* partial merge result (i.e. merge result minus the unmerged entries) |
|
* are stored in 'local_tree', and the OID or the resulting commit |
|
* (to be amended when the conflicts have been resolved) is written into |
|
* 'result_oid'. The unmerged entries are written into the |
|
* .git/NOTES_MERGE_WORKTREE directory with conflict markers. |
|
* -1 is returned. |
|
* |
|
* Both o->local_ref and o->remote_ref must be given (non-NULL), but either ref |
|
* (although not both) may refer to a non-existing notes ref, in which case |
|
* that notes ref is interpreted as an empty notes tree, and the merge |
|
* trivially results in what the other ref points to. |
