There wan't a way for commit_tree() to notice if the message the caller prepared contained a NUL byte, as it did not take the length of the message as a parameter. Use a pointer to a strbuf instead, so that we can either choose to allow low-level plumbing commands to make commits that contain NUL byte in its message, or forbid NUL everywhere by adding the check in commit_tree(), in later patches.

|
|
* contains the updated notes tree, the SHA1 of the resulting commit is
|
|
* written into 'result_sha1', 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 SHA1 or the resulting commit
|
|
* (to be amended when the conflicts have been resolved) is written into
|
|
* 'result_sha1'. 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.
