Submodule UX overhaul updates:
https://lore.kernel.org/git/?q=Submodule+UX+overhaul+update
This series implements branch --recurse-submodules as laid out in the
Submodule branching RFC (linked above). If there are concerns about the
UX/behavior, I would appreciate feedback on the RFC thread as well :)
v6 fixes v5's bad rebase; it was based off a merge commit in 'seen'
instead of js/branch-track-inherit. Since v5 is mostly a no-op, I will
also include a range-diff against v4, which is the last version that
anyone except Junio would care about.
This version is based off Josh's js/branch-track-inherit v7. Because that
is not yet in 'seen', I applied those patches onto abe6bb3905 (The first
batch to start the current cycle, 2021-11-29). The base commit can be
found at https://github.com/chooglen/git/tree/js/branch-track-inherit-v7.
I really hope I got right this time, but if not, hopefully the paper
trail is obvious.
Future work:
* `git branch -d --recurse-submodules` so that users can clean up
extraneous branches.
* `git [checkout | switch] --recurse-submodules` +
submodule.propagateBranches so that users can actually checkout the
branches.
* After [1], it seems clear that --recurse-submodules parsing could
really benefit from some standardization. It's not obvious which
RECURSE_SUBMODULE_* enums are applicable to which commands, and there
is no way to distinguish between an explicit --recurse-submodules from
argv vs submodule.recurse from the config.
I chose not to use them in this series because their usage is already
inconsistent (grep.c doesn't use them either), and it would be _more_
confusing to use the enum (handling RECURSE_SUBMODULES_DEFAULT = 1 is
trickier than boolean 0 and 1).
At this point, I think it would be too noisy to introduce the enum,
but this would be a nice cleanup to do later.
* As documented in branch.c, we create branches using a child process
only because install_branch_config() does not support submodules.
It should be possible to remove the child process once we make the
appropriate changes to config.c. I attempted this in [2] but chose to
punt it because it was too time-consuming at the time.
Changes since v5:
* Rebase onto v7 of js/branch-track-inherit
(https://lore.kernel.org/git/cover.1639717481.git.steadmon@google.com)
Changes since v4:
* Rebase correctly onto 'gitster/seen^{/^Merge branch .js/branch-track-inherit.}'
(see base-commit) as suggested in [3] (thanks Junio!)
* These patches were also verified on top of 'next'.
Changes since v3:
* Split up the old patch 1. Patch 1 had a big diff because it used to
move lines, remove dead code and introduce repo_* functions (thanks
Jonathan!)
** repo_* functions have been dropped; they added noise and are not
necessary for correctness.
* Use a new, harder-to-misuse function in --set-upstream-to,
dwim_and_setup_tracking(). Now, setup_tracking() never does DWIM and
dwim_and_setup_tracking() always does DWIM.
* Move create_branch() dry_run to its own patch.
* Fix an oversight where submodules in subtrees were ignored. This was
because submodules_of_tree() and tree_entry() didn't recurse into
subtrees. Test this accordingly (thanks Jonathan!).
* cmd_branch() possible actions are more consistently ordered.
* Documentation fixes (thanks Philippe!).
* Additional comments and explanation.
* Drop patch 5 (optional cleanup).
* Rebase onto js/branch-track-inherit v6.
Changes since v2:
* Rebase onto js/branch-track-inherit. This series should continue to be
the case going forward.
* Patch 1 has a smaller diff because the introduction of
validate_branch_start() no longer changes the function order thanks to a
forward declaration. This artificial forward declaration is removed in a
patch 2 (which can just be squashed into patch 1).
* Optional cleanup: fix questionable exit codes in patch 5.
Changes since v1:
* Move the functionality of "git branch --dry-run" into "git submodule-helper create-branch --dry-run"
* Add more fields to the submodules_of_tree() struct to reduce the
number of allocations made by the caller. Move this functionality
to patch 3 (formerly patch 4) and drop patch 1.
* Make submodules_of_tree() ignore inactive submodules
* Structure the output of the submodules a bit better by adding prefixes
to the child process' output (instead of inconsistently indenting the
output).
** I wasn't able to find a good way to interleave stdout/stderr
correctly, so a less-than-desirable workaround was to route the child
process output to stdout/stderr depending on the exit code.
** Eventually, I would like to structure the output of submodules in a
report, as Ævar suggested. But at this stage, I think that it's
better to spend time getting user feedback on the submodules
branching UX and it'll be easier to standardize the output when we've
implemented more of the UX :)
