[PATCH 00/13] submodule: convert parts of 'update' to C

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Original series: https://lore.kernel.org/git/20220210092833.55360-1-chooglen@xxxxxxxxxx
(I've trimmed the cc list down to the 'most interested' parties)

= Overview

This is part 1 of 2 series that will supersede ar/submodule-update (as laid out
in [1]). This series prepares for the eventual conversion of "git submodule
update" to C by doing 'obvious' conversions first, and leaving more involved
conversions for later.

Part 1 is a lot simpler than the original series in its entirety, and should
play better with topics that Junio identified:

- This series is based off a later version of 'master' that already has
  'js/apply-partial-clone-filters-recursively' merged in [2].
- There is only one, trivial, conflict with 'es/superproject-aware-submodules'
  (both add tests to the end of t7406) [3].

Most of these patches were originally from ar/submodule-update, but because of
the new organization, some commit messages have been amended to make more sense
in context. However, patches 12 and 13 are new - they were added to handle the
"--filter" option introduced by 'js/apply-partial-clone-filters-recursively'.

Cc-ed Josh, who might be interested in "--filter" changes e.g. the new
tests.

[2] This also fixes some trivial merge conflicts with 'master'.
[3] Part 2 has nontrival conflicts though. Offline, Emily mentioned that
    conflicts might go away in the next iteration of
    'es/superproject-aware-submodules', but if not, the next round of patches
    will probably be based on a merge of this series +
    'es/superproject-aware-submodules'.

= Patch summary

I'm not certain whether to keep patch 13, see the extra discussion in
the --- description for details.

- Patch 1 adds extra tests to "git submodule update" to make sure we
  don't break anything
- Patch 2 removes dead code that used to be part of "git submodule
  update"
- Patch 3 prepares for later changes by introducing the C function that
  will hold most of the newly converted code
- Patch 4 moves run-update-procedure's --suboid option into C
- Patch 5 moves ensure-core-worktree into C
- Patches 6-8 move run-update-procedure's --remote option into C
- Patches 9-11 move "git submodule update"'s --init into C
- Patches 12-13 move "git submodule update"'s --filter option into C
