This split-up isn't as complete as I had hoped - the last patch is still rather large, but breaking that up already took more time than everything else combined, and I think this organization is already easier to review than v5. I'd appreciate any suggestions on how this could be done [1] :) If inspiration strikes, I'll break it up further in a reroll, but as of right now, I'm out of ideas. I did some minimal review of the implementation, but I plan to do more after sending this to the list e.g. I have not revisited the earlier preparatory patches to see if my patches make sense with them. Where I found issues, I left NEEDSWORK comments instead of fixing them because the result would be easier to diff with v5 (the only differences between this tree and v5's is the NEEDSWORK comments). I plan to fix implementation issues (once we've spotted them in reivew) and the NEEDSWORKs in the next reroll. Let me know if the trailers make sense - this is my first time reworking someone else's changes, so I don't think I did a perfect job at attributing work. I also had to fiddle with the Signed-off-by to make them resemble the v5 patches' Signed-off-by (ar/submodule-update seemed to order them differently from v5, I'm not sure why). [1] The difficulty in the last patch comes from the fact that we have the --recursive flag handling in shell, and we are piping update-clone into {run-update-procedure + --recursive flag handling}. Because of how "git submodule" parses args, it is tricky to implement --recursive without bypassing "git submodule" with "git submodule--helper update" (the final patch does this bypass). On the other hand, it's difficult to leave --recursive for last, because we would need to mimic the piping and exiting behavior around update-clone and run-update-procedure. Changes in v6: - Split up last patch of v5 into patches 9-16. - Patches 9-10 are preparatory work on submodule--helper.c. - Patches 11-14 contain sh -> c conversions of the git-submodule.sh code surrounding update-clone and run-update-procedure. - Patch 15 moves functions around in order to shrink patch 16's diff - If reviewers prefer, we could choose _not_ to move the functions around. If so, we can drop patch 15. - Patch 16 introduces "submodule--helper update". Change the commit message to drop references to work done in previous patches. - Add NEEDSWORK comments for potential issues. These will be cleaned up in the next version.
