Subject: [PATCH v7 11/15] merge-octopus: rewrite in C
Date: Wed, 17 Mar 2021 21:49:35 +0100	[thread overview]
Message-ID: <20210317204939.17890-12-alban.gruin@gmail.com> (raw)
In-Reply-To: <20210317204939.17890-1-alban.gruin@gmail.com>

This rewrites `git merge-octopus' from shell to C.  As for the two last
conversions, this port removes calls to external processes to avoid
reading and writing the index over and over again.

 - Calls to `read-tree -u -m (--aggressive)?' are replaced by calls to
   unpack_trees().

 - The call to `write-tree' is replaced by a call to
   write_index_as_tree().

 - The call to `diff-index ...' is replaced by a call to
   repo_index_has_changes().

 - The call to `merge-index', needed to invoke `git merge-one-file', is
   replaced by a call to merge_all_index().

The index is read in cmd_merge_octopus(), and is wrote back by
merge_strategies_octopus().

Here to, merge_strategies_octopus() takes two commit lists and a string
to reduce frictions when try_merge_strategies() will be modified to call
it directly.
