The usage of OPT_CMDMODE() in "cat-file"[1] was added in parallel with
the development of[3] the --batch-all-objects option[4], so we've
since grown[5] checks that it can't be combined with other command
modes, when it should just be made a top-level command-mode
instead. It doesn't combine with --filters, --textconv etc.
By giving parse_options() information about what options are mutually
exclusive with one another we can get the die() message being removed
here for free, we didn't even use that removed message in some cases,
e.g. for both of:
--batch-all-objects --textconv
--batch-all-objects --filters
We'd take the "goto usage" in the "if (opt)" branch, and never reach
the previous message. Now we'll emit e.g.:
$ git cat-file --batch-all-objects --filters
error: option `filters' is incompatible with --batch-all-objects

There's no benefit to defining this at a distance, and it makes the
code harder to read as you've got to scroll up to see the usage that
corresponds to the options.
In subsequent commits I'll make use of usage_msg_opt(), which will be
quite noisy if I have to use the long "cat_file_usage" variable,
there's no other command being defined in this file, so let's rename
it to just "usage".

There were various inaccuracies in the previous SYNOPSIS output,
e.g. "--path" is not something that can optionally go with any options
except --textconv or --filters, as the output implied.
The opening line of the DESCRIPTION section is also "In its first
form[...]", which refers to "git cat-file <type> <object>", but the
SYNOPSIS section wasn't showing that as the first form!
That part of the documentation made sense in
d83a42f34a6 (Documentation: minor grammatical fixes in
git-cat-file.txt, 2009-03-22) when it was introduced, but since then
various options that were added have made that intro make no sense in
the context it was in. Now the two will match again.
The usage output here is not properly aligned on "master" currently,
but will be with my in-flight 4631cfc20bd (parse-options: properly
align continued usage output, 2021-09-21), so let's indent things

Move the handling of the "verbose" flag entirely out of

The expire_reflog_ent() function shouldn't need to deal with the

by doing this the --verbose output becomes backend-agnostic, so
reftable will get the same output.

In the initial implementation of "git reflog" in 4264dc15e19 (git
reflog expire, 2006-12-19) we had this
lookup_commit_reference_gently().
I don't think we've ever found tags that we need to recursively
dereference in reflogs, so this should at least be changed to a
"lookup commit" as I'm doing here, although I can't think of a way
where it mattered in practice.
I also think we'd probably like to just die here if we have a NULL
object, but as this code needs to handle potentially broken
repositories let's just show an "error" but continue, the non-quiet
lookup_commit() will do for us. None of our tests cover the case where

Existing callers to 'git ls-files' are expecting file names, not

However, expert users may want to inspect the contents of the index
itself including which directories are sparse. Add a --sparse option to
allow users to request this information.
During testing, I noticed that options such as --modified did not affect

The 'git fetch' and 'git pull' commands parse the index in order to

this will expand a sparse index, causing slow performance even when
there is no new data to fetch.
The .gitmodules file will never be inside a sparse directory entry, and
even if it was, the index_name_pos() method would expand the sparse

The revision traversal machinery typically processes and returns all
children before any parent. fast-export needs to operate in the
reverse fashion, handling parents before any of their children in
order to build up the history starting from the root commit(s). This
would be a clear case where we could just use the revision traversal
machinery's "reverse" option to achieve this desired affect.
However, this wasn't what the code did. It added its own array for
queuing. The obvious hand-rolled solution would be to just push all
the commits into the array and then traverse afterwards, but it didn't
quite do that either. It instead attempted to process anything it
could as soon as it could, and once it could, check whether it could
process anything that had been queued. As far as I can tell, this was
an effort to save a little memory in the case of multiple root commits
since it could process some commits before queueing all of them. This
involved some helper functions named has_unshown_parent() and
handle_tail(). For typical invocations of fast-export, this
alternative essentially amounted to a hand-rolled method of reversing
the commits -- it was a bunch of work to duplicate the revision
traversal machinery's "reverse" option.
This hand-rolled reversing mechanism is actually somewhat difficult to
reason about. It takes some time to figure out how it ensures in
normal cases that it will actually process all traversed commits
(rather than just dropping some and not printing anything for them).
And it turns out there are some cases where the code does drop commits
without handling them, and not even printing an error or warning for
the user. Due to the has_unshown_parent() checks, some commits could
be left in the array at the end of the "while...get_revision()" loop
which would be unprocessed. This could be triggered for example with
git fast-export main -- --first-parent
or non-sensical traversal rules such as
git fast-export main -- --grep=Merge --invert-grep
While most traversals that don't include all parents should likely
trigger errors in fast-export (or at least require being used in
combination with --reference-excluded-parents), the --first-parent
traversal is at least reasonable and it'd be nice if it didn't just drop
commits. It'd also be nice for future readers of the code to have a
simpler "reverse traversal" mechanism. Use the "reverse" option of the
revision traversal machinery to achieve both.
Even for the non-sensical traversal flags like the --grep one above,
this would be an improvement. For example, in that case, the code
previously would have silently truncated history to only those commits
that do not have an ancestor containing "Merge" in their commit message.
After this code change, that case would include all commits without
"Merge" in their commit message -- but any commit that previously had a
"Merge"-mentioning parent would lose that parent
(likely resulting in many new root commits). While the new behavior is
still odd, it is at least understandable given that
--reference-excluded-parents is not the default.

It can be helpful when creating a new branch to use the existing
tracking configuration from the branch point. However, there is
currently not a method to automatically do so.
Teach git-{branch,checkout,switch} an "inherit" argument to the
"--track" option. When this is set, creating a new branch will cause the
tracking configuration to default to the configuration of the branch
point, if set.
For example, if branch "main" tracks "origin/main", and we run
`git checkout --track=inherit -b feature main`, then branch "feature"
will track "origin/main". Thus, `git status` will show us how far
ahead/behind we are from origin, and `git pull` will pull from origin.
This is particularly useful when creating branches across many
submodules, such as with `git submodule foreach ...` (or if running with
a patch such as [1], which we use at $job), as it avoids having to
manually set tracking info for each submodule.
Since we've added an argument to "--track", also add "--track=direct" as
another way to explicitly get the original "--track" behavior ("--track"
without an argument still works as well).
Finally, teach branch.autoSetupMerge a new "inherit" option. When this
is set, "--track=inherit" becomes the default behavior.

When a series of patches for a topic-B depends on having topic-A,
the workflow to prepare the topic-B branch would look like this:
$ git checkout -b topic-B main
$ git merge --no-ff --no-edit topic-A
$ git am <mbox-for-topic-B
When topic-A gets updated, recreating the first merge and rebasing
the rest of the topic-B, all on detached HEAD, is a useful
technique. After updating topic-A with its new round of patches:
$ git checkout topic-B
$ prev=$(git rev-parse 'HEAD^{/^Merge branch .topic-A. into}')
$ git checkout --detach $prev^1
$ git merge --no-ff --no-edit topic-A
$ git rebase --onto HEAD $prev @{-1}^0
$ git checkout -B @{-1}
This will
(0) check out the current topic-B.
(1) find the previous merge of topic-A into topic-B.
(2) detach the HEAD to the parent of the previous merge.
(3) merge the updated topic-A to it.
(4) reapply the patches to rebuild the rest of topic-B.
(5) update topic-B with the result.
without contaminating the reflog of topic-B too much. topic-B@{1}
is the "logically previous" state before topic-A got updated, for
example. At (4), comparison (e.g. range-diff) between HEAD and
@{-1} is a meaningful way to sanity check the result, and the same
can be done at (5) by comparing topic-B and topic-B@{1}.
But there is one glitch. The merge into the detached HEAD done in
the step (3) above gives us "Merge branch 'topic-A' into HEAD", and
does not say "into topic-B".
Teach the "--into-name=<branch>" option to "git merge" and its
underlying "git fmt-merge-message", to pretend as if we were merging
into <branch>, no matter what branch we are actually merging into,
when they prepare the merge message. The pretend name honors the
usual "into <target>" suppression mechanism, which can be seen in
the tests added here.

While testing some ideas in 'git repack', I ran it with '--quiet' and
discovered that some progress output was still shown. Specifically, the
output for writing the multi-pack-index showed the progress.
The 'show_progress' variable in cmd_repack() is initialized with
isatty(2) and is not modified at all by the '--quiet' flag. The
'--quiet' flag modifies the po_args.quiet option which is translated
into a '--quiet' flag for the 'git pack-objects' child process. However,
'show_progress' is used to directly send progress information to the
multi-pack-index writing logic which does not use a child process.
The fix here is to modify 'show_progress' to be false if po_opts.quiet
is true, and isatty(2) otherwise. This new expectation simplifies a
later condition that checks both.
Update the documentation to make it clear that '-q' will disable all
progress in addition to ensuring the 'git pack-objects' child process
will receive the flag.
Use 'test_terminal' to check that this works to get around the isatty(2)
check.

Historically, we needed a single packfile in order to have reachability
bitmaps. This introduced logic that when 'git repack' had a '-b' option
that we should stop sending the '--honor-pack-keep' option to the 'git
pack-objects' child process, ensuring that we create a packfile
containing all reachable objects.
In the world of multi-pack-index bitmaps, we no longer need to repack
all objects into a single pack to have valid bitmaps. Thus, we should
continue sending the '--honor-pack-keep' flag to 'git pack-objects'.
The fix is very simple: only disable the flag when writing bitmaps but
also _not_ writing the multi-pack-index.
This opens the door to new repacking strategies that might want to keep
some historical set of objects in a stable pack-file while only
repacking more recent objects.
To test, create a new 'test_subcommand_inexact' helper that is more
flexible than 'test_subcommand'. This allows us to look for the
--honor-pack-keep flag without over-indexing on the exact set of
arguments.

or: git stash save [-p|--patch] [-S|--staged] [-k|--[no-]keep-index] [-q|--quiet]

That we emitted the usage for just "push" in the case of the
subcommand not being explicitly specified was an unintentional
side-effect of how it was implemented. When it was converted to C in
d553f538b8a (stash: convert push to builtin, 2019-02-25) the pattern
of having per-subcommand usage information was rightly continued. The
"git-stash.sh" shellscript did not have that, and always printed the
equivalent of "git_stash_usage".
But in doing so the case of push being implicit and explicit was
conflated. A variable was added to track this in 8c3713cede7 (stash:
eliminate crude option parsing, 2020-02-17), but it did not update the
usage output accordingly.
This still leaves e.g. "git stash push -h" emitting the
"git_stash_usage" output, instead of "git_stash_push_usage". That
should be fixed, but is a much deeper misbehavior in parse_options()
not being aware of subcommands at all. I.e. in how
PARSE_OPT_KEEP_UNKNOWN and PARSE_OPT_NO_INTERNAL_HELP combine in
commands such as "git stash".
Perhaps PARSE_OPT_KEEP_UNKNOWN should imply
PARSE_OPT_NO_INTERNAL_HELP, or better yet parse_options() should be
extended to fully handle these subcommand cases that we handle
manually in "git stash", "git commit-graph", "git multi-pack-index"
etc. All of those musings would be a much bigger change than this
isolated fix though, so let's leave that for some other time.

The previously suggested workflow:

git sparse-checkout set ...
Suffered from three problems:
1) It would delete nearly all files in the first step, then
restore them in the second. That was poor performance and
forced unnecessary rebuilds.
2) The two-step process resulted in two progress bars, which
was suboptimal from a UI point of view for wrappers that
invoked both of these commands but only exposed a single
command to their end users.
3) With cone mode, the first step would delete nearly all
ignored files everywhere, because everything was considered
to be outside of the specified sparsity paths. (The user was
not allowed to specify any sparsity paths in the `init` step.)
Avoid these problems by teaching `set` to understand the extra

Most sparse-checkout subcommands (list, add, reapply) only make sense
when already in a sparse state. Add a quick check that will error out
early if this is not the case.
Also document with a comment why we do not exit early in `disable` even
when core.sparseCheckout starts as false.

sparse_checkout_set() was reused by sparse_checkout_add() with the only
difference being a single parameter being passed to that function.
However, we would like sparse_checkout_set() to do the same work that
sparse_checkout_init() does if sparse checkouts are not already enabled.
To facilitate this transition, give each mode their own copy of the
function. This does not introduce any behavioral changes; that will
come in a subsequent patch.

add_patterns_from_input() has relied on a global variable,
set_opts.use_stdin, which has been used by both the `set` and `add`
subcommands of sparse-checkout. Once we introduce an
add_opts.use_stdin, the hardcoding of set_opts.use_stdin will be
incorrect. Pass the value as function parameter instead to allow us to
make subsequent changes.

Code clean-up.
* ab/die-with-bug:
object.c: use BUG(...) no die("BUG: ...") in lookup_object_by_type()
pathspec: use BUG(...) not die("BUG:%s:%d....", <file>, <line>)
strbuf.h: use BUG(...) not die("BUG: ...")
pack-objects: use BUG(...) not die("BUG: ...")
"git worktree add" showed "Preparing worktree" message to the
standard output stream, but when it failed, the message from die()
went to the standard error stream. Depending on the order the
stdio streams are flushed at the program end, this resulted in
confusing output. It has been corrected by sending all the chatty
messages to the standard error stream.
* es/worktree-chatty-to-stderr:
git-worktree.txt: add missing `-v` to synopsis for `worktree list`
worktree: send "chatty" messages to stderr
Prepare tests on ref API to help testing reftable backends.
* hn/reflog-tests:
refs/debug: trim trailing LF from reflog message
test-ref-store: tweaks to for-each-reflog-ent format
t1405: check for_each_reflog_ent_reverse() more thoroughly
test-ref-store: don't add newline to reflog message
show-branch: show reflog message
When the "git push" command is killed while the receiving end is
trying to report what happened to the ref update proposals, the
latter used to die, due to SIGPIPE. The code now ignores SIGPIPE
to increase our chances to run the post-receive hook after it
happens.
* rj/receive-pack-avoid-sigpipe-during-status-reporting:
receive-pack: ignore SIGPIPE while reporting status to client
API clean-up.
* ab/run-command:
run-command API: remove "env" member, always use "env_array"
difftool: use "env_array" to simplify memory management
run-command API: remove "argv" member, always use "args"
run-command API users: use strvec_push(), not argv construction
run-command API users: use strvec_pushl(), not argv construction
run-command tests: use strvec_pushv(), not argv assignment
run-command API users: use strvec_pushv(), not argv assignment
upload-archive: use regular "struct child_process" pattern
worktree: stop being overly intimate with run_command() internals
"Zealous diff3" style of merge conflict presentation has been added.
* en/zdiff3:
update documentation for new zdiff3 conflictStyle
xdiff: implement a zealous diff3, or "zdiff3"
"git submodule deinit" for a submodule whose .git metadata
directory is embedded in its working tree refused to work, until
the submodule gets converted to use the "absorbed" form where the
metadata directory is stored in superproject, and a gitfile at the
top-level of the working tree of the submodule points at it. The
command is taught to convert such submodules to the absorbed form
as needed.
* mp/absorb-submodule-git-dir-upon-deinit:
submodule: absorb git dir instead of dying on deinit
Various operating modes of "git reset" have been made to work
better with the sparse index.
* vd/sparse-reset:
unpack-trees: improve performance of next_cache_entry
reset: make --mixed sparse-aware
reset: make sparse-aware (except --mixed)
reset: integrate with sparse index
reset: expand test coverage for sparse checkouts
sparse-index: update command for expand/collapse test
reset: preserve skip-worktree bit in mixed reset
reset: rename is_missing to !is_in_reset_tree
On platforms where ulong is shorter than size_t, code paths that
shifted 1 or 1U to the left lacked the necessary cast to size_t,
which have been corrected.
* po/size-t-for-vs:
object-file.c: LLP64 compatibility, upcast unity for left shift
diffcore-delta.c: LLP64 compatibility, upcast unity for left shift
repack.c: LLP64 compatibility, upcast unity for left shift
The advice message given by "git pull" when the user hasn't made a
choice between merge and rebase still said that the merge is the
default, which no longer is the case. This has been corrected.
* ah/advice-pull-has-no-preference-between-rebase-and-merge:
pull: don't say that merge is "the default strategy"
