NOTES MERGE STRATEGIES
|
||||
----------------------
|
||||
|
||||
The default notes merge strategy is "manual", which checks out
|
||||
conflicting notes in a special work tree for resolving notes conflicts
|
||||
(`.git/NOTES_MERGE_WORKTREE`), and instructs the user to resolve the
|
||||
conflicts in that work tree.
|
||||
When done, the user can either finalize the merge with
|
||||
'git notes merge --commit', or abort the merge with
|
||||
'git notes merge --abort'.
|
||||
|
||||
"ours" automatically resolves conflicting notes in favor of the local
|
||||
version (i.e. the current notes ref).
|
||||
|
||||
"theirs" automatically resolves notes conflicts in favor of the remote
|
||||
version (i.e. the given notes ref being merged into the current notes
|
||||
ref).
|
||||
|
||||
"union" automatically resolves notes conflicts by concatenating the
|
||||
local and remote versions.
|
||||
|
||||
"cat_sort_uniq" is similar to "union", but in addition to concatenating
|
||||
the local and remote versions, this strategy also sorts the resulting
|
||||
lines, and removes duplicate lines from the result. This is equivalent
|
||||
to applying the "cat | sort | uniq" shell pipeline to the local and
|
||||
remote versions. This strategy is useful if the notes follow a line-based
|
||||
format where one wants to avoid duplicated lines in the merge result.
|
||||
Note that if either the local or remote version contain duplicate lines
|
||||
prior to the merge, these will also be removed by this notes merge
|
||||
strategy.

There are three files foo/bar/baz, and the following graph illustrates the

content of these files in each commit:
|

|

# foo/bar/baz --- foo/bar/bazz <-- master
|

# \
|

# --- foo/barf/bazf <-- conflict_branch
|

# \
|
||||
# --- foo/bart/baz <-- clean_branch
|
||||
|
||||
Next, test git merge --abort with the following variables:
|
||||
- before/after successful merge (should fail when not in merge context)
|
||||
- with/without conflicts
|
||||
- clean/dirty index before merge
|
||||
- clean/dirty worktree before merge
|

- dirty index before merge matches contents on remote branch

- changed/unchanged worktree after merge

- changed/unchanged index after merge
