From 6abb3655efe364cf0375b5cdae2729af7562ed45 Mon Sep 17 00:00:00 2001 From: Johan Herland Date: Tue, 9 Nov 2010 22:49:52 +0100 Subject: git notes merge: Manual conflict resolution, part 2/2 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When the notes merge conflicts in .git/NOTES_MERGE_WORKTREE have been resolved, we need to record a new notes commit on the appropriate notes ref with the resolved notes. This patch implements 'git notes merge --commit' which the user should run after resolving conflicts in the notes merge worktree. This command finalizes the notes merge by recombining the partial notes tree from part 1 with the now-resolved conflicts in the notes merge worktree in a merge commit, and updating the appropriate ref to this merge commit. In order to correctly finalize the merge, we need to keep track of three things: - The partial merge result from part 1, containing the auto-merged notes. This is now stored into a ref called .git/NOTES_MERGE_PARTIAL. - The unmerged notes. These are already stored in .git/NOTES_MERGE_WORKTREE, thanks to part 1. - The notes ref to be updated by the finalized merge result. This is now stored in a symref called .git/NOTES_MERGE_REF. In addition to "git notes merge --commit", which uses the above details to create the finalized notes merge commit, this patch also implements "git notes merge --reset", which aborts the ongoing notes merge by simply removing the files/directory described above. FTR, "git notes merge --commit" reuses "git notes merge --reset" to remove the information described above (.git/NOTES_MERGE_*) after the notes merge have been successfully finalized. The patch also contains documentation and testcases for the two new options. This patch has been improved by the following contributions: - Ævar Arnfjörð Bjarmason: Fix nonsense sentence in --commit description - Sverre Rabbelier: Rename --reset to --abort Thanks-to: Ævar Arnfjörð Bjarmason Thanks-to: Sverre Rabbelier Signed-off-by: Johan Herland Signed-off-by: Junio C Hamano --- notes-merge.h | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) (limited to 'notes-merge.h') diff --git a/notes-merge.h b/notes-merge.h index 55ef3d957f..aa756931a5 100644 --- a/notes-merge.h +++ b/notes-merge.h @@ -71,4 +71,27 @@ int notes_merge(struct notes_merge_options *o, struct notes_tree *local_tree, unsigned char *result_sha1); +/* + * Finalize conflict resolution from an earlier notes_merge() + * + * The given notes tree 'partial_tree' must be the notes_tree corresponding to + * the given 'partial_commit', the partial result commit created by a previous + * call to notes_merge(). + * + * This function will add the (now resolved) notes in .git/NOTES_MERGE_WORKTREE + * to 'partial_tree', and create a final notes merge commit, the SHA1 of which + * will be stored in 'result_sha1'. + */ +int notes_merge_commit(struct notes_merge_options *o, + struct notes_tree *partial_tree, + struct commit *partial_commit, + unsigned char *result_sha1); + +/* + * Abort conflict resolution from an earlier notes_merge() + * + * Removes the notes merge worktree in .git/NOTES_MERGE_WORKTREE. + */ +int notes_merge_abort(struct notes_merge_options *o); + #endif -- cgit v1.2.1
