reset [--mixed]: only write index file once
When doing a mixed reset without paths, the index is locked, read, reset, and written back as part of the actual reset operation (in reset_index()). Then, when showing the list of worktree modifications, we lock the index again, refresh it, and write it. Change this so we only write the index once, making "git reset" a little faster. It does mean that the index lock will be held a little longer, but the difference is small compared to the time spent refreshing the index. There is one minor functional difference: We used to say "Could not write new index file." if the first write failed, and "Could not refresh index" if the second write failed. Now, we will only use the first message. This speeds up "git reset" a little on the linux-2.6 repo (best of five, warm cache): Before After real 0m0.239s 0m0.214s user 0m0.160s 0m0.130s sys 0m0.070s 0m0.080s Signed-off-by: Martin von Zweigbergk <martinvonz@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
