In bcfc82bd48 (branch: description for non-existent branch errors,
2022-10-08) we checked the HEAD in the current worktree to detect if the
branch to operate with is an orphan branch, so as to avoid the confusing
error: "No branch named...".
If we are asked to operate with an orphan branch in a different working
tree than the current one, we need to check the HEAD in that different
working tree.
Let's extend the check we did in bcfc82bd48, to check the HEADs in all
worktrees linked to the current repository, using the helper introduced
in 31ad6b61bd (branch: add branch_checked_out() helper, 2022-06-15).
The helper, branch_checked_out(), does its work obtaining internally a
list of worktrees linked to the current repository. Obtaining that list
is not a lightweight work because it implies disk access.
In copy_or_rename_branch() we already have a list of worktrees. Let's
use that already obtained list, and avoid using here the helper.

When we introduced replace_each_worktree_head_symref() in 70999e9cec
(branch -m: update all per-worktree HEADs, 2016-03-27), we implemented a
best effort approach.
If we are asked to rename a branch that is simultaneously checked out in
multiple worktrees, we try to update all of those worktrees. If we fail
updating any of them, we die() as a signal that something has gone
wrong. However, at this point, the branch ref has already been renamed
and also updated the HEADs of the successfully updated worktrees.
Despite returning an error, we do not try to rollback those changes.
Let's add a test to notice if we change this behavior in the future.
In next commits we will change replace_each_worktree_head_symref() to
work more closely with its only caller, copy_or_rename_branch(). Let's
move the former closer to its caller, to facilitate those changes.

In c3b58472be (pack-redundant: gauge the usage before proposing its
removal, 2020-08-25), we added a big, ugly warning when pack-redundant
is run. The plan there indicated that we would ratchet that up to an
error before finally removing it. Since it has been 2.5 years (and 9
releases) since then, let's continue with the plan.
Note that we did get one bite on the warning, which was somebody asking
about alternatives:
https://lore.kernel.org/git/CAKvOHKAFXQwt4D8yUCCkf_TQL79mYaJ=KAKhtpDNTvHJFuX1NA@mail.gmail.com/
but we didn't undo the ugly warning (and the advice continues to be "use
repack -d" instead).
There was also some discussion around the time of the deprecation that
pack-redundant was invoked by the bitbake tool, and it still seems to do
so now:
https://git.openembedded.org/bitbake
That use should probably just go away in favor of an occasional repack
(which probably even happens via auto-gc after fetch these days).
But since neither of those data points caused us to cancel the
deprecation plan by dropping the warning, it seems like we should
proceed with the next step.

The anonymization code has a specific generator callback for each type
of data (e.g., one for paths, one for oids, and so on). These all take a
"data" parameter, but none of them use it for anything. Which is not
surprising, as the point is to generate a new name independent of any
input, and each function keeps its own static counter.
We added the extra pointer in d5bf91fde4 (fast-export: add a "data"
callback parameter to anonymize_str(), 2020-06-23) to handle
--anonymize-map parsing, but that turned out to be awkward itself, and
was recently dropped.
So let's get rid of this "data" parameter that nobody is using, both
from the generators and from anonymize_str() which plumbed it through.
This simplifies the code, and makes -Wunused-parameter happier.

When we handle an --anonymize-map option, we parse the orig/anon pair,
and then feed the "orig" string to anonymize_str(), along with a
generator function that duplicates the "anon" string to be cached in the
map.
This works, because anonymize_str() says "ah, there is no mapping yet
for orig; I'll add one from the generator". But there are some
downsides:
1. It's a bit too clever, as it's not obvious what the code is trying
to do or why it works.
2. It requires allowing generator functions to take an extra void
pointer, which is not something any of the normal callers of
anonymize_str() want.
3. It does the wrong thing if the same token is provided twice.
When there are conflicting options, like:
git fast-export --anonymize \
--anonymize-map=foo:one \
--anonymize-map=foo:two
we usually let the second one override the first. But by using
anonymize_str(), which has first-one-wins logic, we do the
opposite.
So instead of relying on anonymize_str(), let's directly add the entry
ourselves. We can tweak the tests to show that we handle overridden
options correctly now.

When anonymizing output, there's only one spot where we generate new
entries to add to our hashmap: when anonymize_str() doesn't find an
entry, we use the generate() callback to make one and add it. Let's pull
that into its own function in preparation for another caller.
Note that we'll add one extra feature. In anonymize_str(), we know that
we won't find an existing entry in the hashmap (since it will only try
to add after failing to find one). But other callers won't have the same
behavior, so we should catch this case and free the now-dangling entry.

call functions on a zero-initialized table; it will just correctly
return NULL, since there is no match.
This simplifies the code a little, and also lets us keep the
initialization line closer to when we add an entry (which is when the
hashmap really does need to be totally initialized). That will help

The previous change implemented the ahead_behind() method, including an
algorithm to compute the ahead/behind values for a number of commit tips
relative to a number of commit bases. Now, integrate that algorithm as
part of 'git for-each-ref' hidden behind a new format atom,
ahead-behind. This naturally extends to 'git branch' and 'git tag'
builtins, as well.
This format allows specifying multiple bases, if so desired, and all
matching references are compared against all of those bases. For this
reason, failing to read a reference provided from these atoms results in
an error.
In order to translate the ahead_behind() method information to the
format output code in ref-filter.c, we must populate arrays of
ahead_behind_count structs. In struct ref_array, we store the full array
that will be passed to ahead_behind(). In struct ref_array_item, we
store an array of pointers that point to the relvant items within the
full array. In this way, we can pull all relevant ahead/behind values
directly when formatting output for a specific item. It also ensures the
lifetime of the ahead_behind_count structs matches the time that the
array is being used.
Add specific tests of the ahead/behind counts in t6600-test-reach.sh, as
it has an interesting repository shape. In particular, its merging
strategy and its use of different commit-graphs would demonstrate over-
counting if the ahead_behind() method did not already account for that
possibility.
Also add tests for the specific for-each-ref, branch, and tag builtins.
In the case of 'git tag', there are intersting cases that happen when
some of the selected tips are not commits. This requires careful logic
around commits_nr in the second loop of filter_ahead_behind(). Also, the
test in t7004 is carefully located to avoid being dependent on the GPG
prereq. It also avoids using the test_commit helper, as that will add
ticks to the time and disrupt the expected timestamps in later tag
tests.
Also add performance tests in a new p1300-graph-walks.sh script. This
will be useful for more uses in the future, but for now compare the
ahead-behind counting algorithm in 'git for-each-ref' to the naive
implementation by running 'git rev-list --count' processes for each
input.
For the Git source code repository, the improvement is already obvious:
Test this tree
---------------------------------------------------------------
1500.2: ahead-behind counts: git for-each-ref 0.07(0.07+0.00)

1500.5: ahead-behind counts: git rev-list 1.32(1.04+0.27)
But the standard performance benchmark is the Linux kernel repository,
which demosntrates a significant improvement:

1500.5: ahead-behind counts: git rev-list 4.57(4.03+0.54)

When a user wishes to input a large list of patterns to 'git
for-each-ref' (likely a long list of exact refs) there are frequently
system limits on the number of command-line arguments.
Add a new --stdin option to instead read the patterns from standard
input. Add tests that check that any unrecognized arguments are
considered an error when --stdin is provided. Also, an empty pattern
list is interpreted as the complete ref set.
When reading from stdin, we populate the filter.name_patterns array
dynamically as opposed to pointing to the 'argv' array directly. This is
simple when using a strvec, as it is NULL-terminated in the same way. We
then free the memory directly from the strvec.

When fetching from a remote, we not only print the actual references
that have changed, but will also print the URL from which we have
fetched them to standard output. The logic to handle this is duplicated
across two different callsites with some non-trivial logic to compute
the anonymized URL. Furthermore, we're using global state to track
whether we have already shown the URL to the user or not.
Refactor the code by moving it into `format_display()`. Like this, we
can convert the global variable into a member of `display_state`. And
second, we can deduplicate the logic to compute the anonymized URL.

The function `format_display()` is used to print a single reference
update to a buffer which will then ultimately be printed by the caller.
This architecture causes us to duplicate some logic across the different
callsites of this function. This makes it hard to follow the code as
some parts of the logic are located in one place, while other parts of
the logic are located in a different place. Furthermore, by having the
logic scattered around it becomes quite hard to implement a new output
format for the reference updates.
We can make the logic a whole lot easier to understand by making the
`format_display()` function self-contained so that it handles formatting
and printing of the references. This will eventually allow us to easily
implement a completely different output format, but also opens the door
to conditionally print to either stdout or stderr depending on the
output format.
As a first step towards that goal we move the formatting directive used
by both callers to print a single reference update into this function.

Before printing the name of the local references that would be updated
by a fetch we first prettify the reference name. This is done at the
calling side so that `format_display()` never sees the full name of the
local reference. This restricts our ability to introduce new output
formats that might want to print the full reference name.
Right now, all callsites except one are prettifying the reference name
anyway. And the only callsite that doesn't passes `FETCH_HEAD` as the
hardcoded reference name to `format_display()`, which would never be
changed by a call to `prettify_refname()` anyway. So let's refactor the

There's code in git_connect() that checks whether we are doing a push
with protocol_v2, and if so, drops us to protocol_v0 (since we know
how to do v2 only for fetches). But it misses some corner cases:
1. it checks the "prog" variable, which is actually the path to
receive-pack on the remote side. By default this is just
"git-receive-pack", but it could be an arbitrary string (like
"/path/to/git receive-pack", etc). We'd accidentally stay in v2
mode in this case.
2. besides "receive-pack" and "upload-pack", there's one other value
we'd expect: "upload-archive" for handling "git archive --remote".
Like receive-pack, this doesn't understand v2, and should use the
v0 protocol.
In practice, neither of these causes bugs in the real world so far. We
do send a "we understand v2" probe to the server, but since no server
implements v2 for anything but upload-pack, it's simply ignored. But
this would eventually become a problem if we do implement v2 for those
endpoints, as older clients would falsely claim to understand it,
leading to a server response they can't parse.
We can fix (1) by passing in both the program path and the "name" of the
operation. I treat the name as a string here, because that's the pattern
set in transport_connect(), which is one of our callers (we were simply
throwing away the "name" value there before).
We can fix (2) by allowing only known-v2 protocols ("upload-pack"),
rather than blocking unknown ones ("receive-pack" and "upload-archive").
That will mean whoever eventually implements v2 push will have to adjust
this list, but that's reasonable. We'll do the safe, conservative thing
(sticking to v0) by default, and anybody working on v2 will quickly
realize this spot needs to be updated.
The new tests cover the receive-pack and upload-archive cases above, and
re-confirm that we allow v2 with an arbitrary "--upload-pack" path (that
already worked before this patch, of course, but it would be an easy
thing to break if we flipped the allow/block logic without also handling
"name" separately).
Here are a few miscellaneous implementation notes, since I had to do a
little head-scratching to understand who calls what:
- transport_connect() is called only for git-upload-archive. For
non-http git remotes, that resolves to the virtual connect_git()
function (which then calls git_connect(); confused yet?). So
plumbing through "name" in connect_git() covers that.
- for regular fetches and pushes, callers use higher-level functions
like transport_fetch_refs(). For non-http git remotes, that means
calling git_connect() under the hood via connect_setup(). And that
uses the "for_push" flag to decide which name to use.
- likewise, plumbing like fetch-pack and send-pack may call
git_connect() directly; they each know which name to use.
- for remote helpers (including http), we already have separate
parameters for "name" and "exec" (another name for "prog"). In
process_connect_service(), we feed the "name" to the helper via
"connect" or "stateless-connect" directives.
There's also a "servpath" option, which can be used to tell the
helper about the "exec" path. But no helpers we implement support
it! For http it would be useless anyway (no reasonable server
implementation will allow you to send a shell command to run the
server). In theory it would be useful for more obscure helpers like
remote-ext, but even there it is not implemented.
It's tempting to get rid of it simply to reduce confusion, but we
have publicly documented it since it was added in fa8c097cc9
(Support remote helpers implementing smart transports, 2009-12-09),
so it's possible some helper in the wild is using it.
- So for v2, helpers (again, including http) are mainly used via
stateless-connect, driven by the main program. But they do still
need to decide whether to do a v2 probe. And so there's similar
logic in remote-curl.c's discover_refs() that looks for
"git-receive-pack". But it's not buggy in the same way. Since it
doesn't support servpath, it is always dealing with a "service"
string like "git-receive-pack". And since it doesn't support
straight "connect", it can't be used for "upload-archive".
So we could leave that spot alone. But I've updated it here to match
the logic we're changing in connect_git(). That seems like the least
confusing thing for somebody who has to touch both of these spots
later (say, to add v2 push support). I didn't add a new test to make
sure this doesn't break anything; we already have several tests (in
t5551 and elsewhere) that make sure we are using v2 over http.

Code clean-up to clarify the rule that "git-compat-util.h" must be
the first to be included.
* en/header-cleanup:
diff.h: remove unnecessary include of object.h
Remove unnecessary includes of builtin.h
treewide: replace cache.h with more direct headers, where possible
replace-object.h: move read_replace_refs declaration from cache.h to here
object-store.h: move struct object_info from cache.h
dir.h: refactor to no longer need to include cache.h
object.h: stop depending on cache.h; make cache.h depend on object.h
ident.h: move ident-related declarations out of cache.h
pretty.h: move has_non_ascii() declaration from commit.h
cache.h: remove dependence on hex.h; make other files include it explicitly
hex.h: move some hex-related declarations from cache.h
hash.h: move some oid-related declarations from cache.h
alloc.h: move ALLOC_GROW() functions from cache.h
treewide: remove unnecessary cache.h includes in source files
treewide: remove unnecessary cache.h includes
treewide: remove unnecessary git-compat-util.h includes in headers
treewide: ensure one of the appropriate headers is sourced first

unpack-trees: add usage notices around df_conflict_entry
unpack-trees: special case read-tree debugging as internal usage
unpack-trees: rewrap a few overlong lines from previous patch
unpack-trees: mark fields only used internally as internal
unpack_trees: start splitting internal fields from public API
sparse-checkout: avoid using internal API of unpack-trees, take 2
sparse-checkout: avoid using internal API of unpack-trees
unpack-trees: clean up some flow control
dir: mark output only fields of dir_struct as such
dir: add a usage note to exclude_per_dir
dir: separate public from internal portion of dir_struct

t2021: fix platform-specific leftover cruft
"git fsck" learned to check the index files in other worktrees,
just like "git gc" honors them as anchoring points.
* jk/fsck-indices-in-worktrees:
fsck: check even zero-entry index files
fsck: mention file path for index errors
fsck: check index files in all worktrees
fsck: factor out index fsck
When git-rebase invokes format-patch, it wants to make sure we use the
normal prefixes, and are not confused by diff.noprefix or similar. When
this was added in 5b220a6876 (Add --src/dst-prefix to git-formt-patch
in git-rebase.sh, 2010-09-09), we only had --src-prefix and --dst-prefix
to do so, which requires re-specifying the prefixes we expect to see.
These days we can say what we want more directly: just use the defaults.
This is a minor cleanup that should have no behavior change, but
hopefully the result expresses more clearly what the code is trying to
accomplish.

Fix a bug introduced with the "--format" option in
ce74de93 (ls-files: introduce "--format" option, 2022-07-23),
where relative paths were computed using the output buffer,
which could lead to random garbage data in the output.

When accepting a packfile in git-receive-pack(1), we feed that packfile
into git-index-pack(1) to generate the packfile index. As the packfile
would often only contain unreachable objects until the references have
been updated, concurrently running garbage collection might be tempted
to delete the packfile right away and thus cause corruption. To fix
this, we ask git-index-pack(1) to create a `.keep` file before moving
the packfile into place, which is getting deleted again once all of the
reference updates have been processed.
Now in production systems we have observed that those `.keep` files are
sometimes not getting deleted as expected, where the result is that
repositories tend to grow packfiles that are never deleted over time.
This seems to be caused by a race when git-receive-pack(1) is killed
after we have migrated the kept packfile from the quarantine directory
into the main object database. While this race window is typically small
it can be extended for example by installing a `proc-receive` hook.
Fix this race by registering the lockfile as a tempfile so that it will
automatically be removed at exit or when receiving a signal.

It seems a user would expect this option would work regardless
of whether it's fetching from a single remote, many remotes,
or recursing into submodules.
