Subject: [PATCH v5 03/12] merge-one-file: rewrite in C
Date: Mon, 16 Nov 2020 11:21:49 +0100	[thread overview]
Message-ID: <20201116102158.8365-4-alban.gruin@gmail.com> (raw)
In-Reply-To: <20201116102158.8365-1-alban.gruin@gmail.com>

This rewrites `git merge-one-file' from shell to C.  This port is not
completely straightforward: to save precious cycles by avoiding reading
and flushing the index repeatedly, write temporary files when an
operation can be performed in-memory, or allow other function to use the
rewrite without forking nor worrying about the index, the calls to
external processes are replaced by calls to functions in libgit.a:

 - calls to `update-index --add --cacheinfo' are replaced by calls to
   add_to_index_cacheinfo();

 - calls to `update-index --remove' are replaced by calls to
   remove_file_from_index();

 - calls to `checkout-index -u -f' are replaced by calls to
   checkout_entry();

 - calls to `unpack-file' and `merge-files' are replaced by calls to
   read_mmblob() and xdl_merge(), respectively, to merge files
   in-memory;

 - calls to `checkout-index -f --stage=2' are removed, as this is needed
   to have the correct permission bits on the merged file from the
   script, but not in the C version;

 - calls to `update-index' are replaced by calls to add_file_to_index().

The bulk of the rewrite is done in a new file in libgit.a,
merge-strategies.c.  This will enable the resolve and octopus strategies
to directly call it instead of forking.

This also fixes a bug present in the original script: instead of
checking if a _regular_ file exists when a file exists in the branch to
merge, but not in our branch, the rewritten version checks if a file of
any kind (ie. a directory, ...) exists.  This fixes the tests t6035.14,
where the branch to merge had a new file, `a/b', but our branch had a
directory there; it should have failed because a directory exists, but
it did not because there was no regular file called `a/b'.  This test is
now marked as successful.
