When reading input with the `--cruft` option, `git pack-objects` reads
each line into a strbuf, and then moves it to either the list of
discarded or fresh packs, depending on whether or not the input line
starts with a '-' character.
At the beginning of each loop iteration, the next line of input is read
with `strbuf_getline()`, which calls `strbuf_reset()` (as a part of
`strbuf_getwholeline()`) before reading the next line of input.
Thus, the call to `strbuf_reset()` (added back in b757353676
(builtin/pack-objects.c: --cruft without expiration, 2022-05-20)) at the
end of the loop is unnecessary, so let's remove it accordingly.

The transfer.unpackLimit configuration variable is documented to be
used only as a fallback value when the more operation-specific
fetch.unpackLimit and receive.unpackLimit variables are not set, but
the implementation had the precedence reversed. Apparently this was
broken since the transfer.unpackLimit was introduced in e28714c5
(Consolidate {receive,fetch}.unpackLimit, 2007-01-24).
Often when documentation and code have diverged for so long, we
prefer to change the documentation instead, to avoid disrupting
users. But doing so would make these weirdly unlike most other
"specific overrides general" config options. And the fact that the
bug has existed for so long without anyone noticing implies to me
that nobody really tries to mix and match them much.

Many programs use diff_result_code() to get a user-visible program exit
code from a diff result (e.g., checking opts.found_changes if
--exit-code was requested).
This function also takes a "status" parameter, which seems at first
glance that it could be used to propagate an error encountered when
computing the diff. But it doesn't work that way:
- negative values are passed through as-is, but are not appropriate as
program exit codes
- when --exit-code or --check is in effect, we _ignore_ the passed-in
status completely. So a failed diff which did not have a chance to
set opts.found_changes would erroneously report "success, no
changes" instead of propagating the error.
After recent cleanups, neither of these bugs is possible to trigger, as
every caller just passes in "0". So rather than fixing them, we can
simply drop the useless parameter instead.

Since git-diff has many diff modes, it dispatches to many helpers to
perform each one. But every helper simply returns "0", as it exits
directly if there are serious errors (and options like --exit-code are
handled afterwards). So let's get rid of these useless return values,
which makes the code flow more clear.
There's very little chance that we'd later want to propagate errors
instead of dying immediately. These are all static-local helpers for the
git-diff program implementing its various modes. More "lib-ified" code
would directly call the underlying functions.

Neither of these functions ever returns a value other than zero.
Instead, they expect unrecoverable errors to exit immediately, and
things like "--exit-code" are stored inside the diff_options struct to
be handled later via diff_result_code().
Some callers do check the return values, but many don't bother. Let's
drop the useless return values, which are misleading callers about how
the functions work. This could be seen as a step in the wrong direction,
as we might want to eventually "lib-ify" these to more cleanly return
errors up the stack, in which case we'd have to add the return values
back in. But there are some benefits to doing this now:
1. In the current code, somebody could accidentally add a "return -1"
to one of the functions, which would be erroneously ignored by many
callers. By removing the return code, the compiler can notice the
mismatch and force the developer to decide what to do.
Obviously the other option here is that we could start consistently
checking the error code in every caller. But it would be dead code,
and we wouldn't get any compile-time help in catching new cases.
2. It communicates the situation to callers, who may want to choose a
different function. These functions are really thin wrappers for
doing git-diff-files and git-diff-index within the process. But
callers who care about recovering from an error here are probably
better off using the underlying library functions, many of
which do return errors.
If somebody eventually wants to teach these functions to propagate
errors, they'll have to switch back to returning a value, effectively
reverting this patch. But at least then they will be starting with a
level playing field: they know that they will need to inspect each
caller to see how it should handle the error.

When the git-diff program fails to read the index in its diff-files or
diff-index helper functions, it propagates the error up the stack. This
eventually lands in diff_result_code(), which does not handle it well
(as discussed in the previous patch).
Since the only sensible thing here is to exit with an error code (and
what we were expecting the propagated error code to cause), let's just
do that directly.
There's no test here, as I'm not even sure this case can be triggered.
The index-reading functions tend to die() themselves when encountering
any errors, and the return value is just the number of entries in the
file (and so always 0 or positive). But let's err on the conservative
side and keep checking the return value. It may be worth digging into as
a separate topic (though index-reading is low-level enough that we
probably want to eventually teach it to propagate errors anyway for
lib-ification purposes, at which point this code would already be doing
the right thing).

The git-diff command has many modes (comparing worktree to index, index
to HEAD, individual blobs, etc). As a result, it dispatches to many
helper functions and cannot completely parse its options until we're in
those helper functions.
Most of them, when seeing an unknown option, exit immediately by calling
usage(). But builtin_diff_files(), which is the default if no revision
or blob arguments are given, instead prints an error() and returns -1.
One obvious shortcoming here is that the user doesn't get to see the
usual usage message. But there's a much more important bug: the -1
return is fed to diff_result_code(), which is not ready to handle it.
By default, it passes the code along as an exit code. We try to avoid
negative exit codes because they get converted to unsigned values, but
it should at least consistently show up as non-zero (i.e., a failure).
But much worse is that when --exit-code is in effect, diff_result_code()
will _ignore_ the status passed in by the caller, and instead only
report on whether the diff found changes. It didn't, of course, because
we never ran the diff, and the program unexpectedly exits with success!
We can fix this bug by just calling usage(), like the other helpers do.
Another option would of course be to teach diff_result_code() to handle
this value. But as we'll see in the next few patches, it can be cleaned
up even further. Let's just fix this bug directly to start with.

If loading the index fails, we print an error and then return "-1" from
the function. But since this is a builtin, we end up with exit(-1),
which produces odd results since program exit codes are unsigned.
Because of integer conversion, it usually becomes 255, which is at least
still an error, but values above 128 are usually interpreted as signal
death.
Since we know the program is exiting immediately, we can just replace
the error return with a die().

Many callers of run_diff_index() passed literal "1" for the option
flag word, which should better be spelled out as DIFF_INDEX_CACHED
for readablity. Everybody else passes "0" that can stay as-is.
The other bit in the option flag word is DIFF_INDEX_MERGE_BASE, but
curiously there is only one caller that can pass it, which is "git
diff-index --merge-base" itself---no internal callers uses the
feature.
A bit tricky call to the function is in builtin/submodule--helper.c
where the .cached member in a private struct is set/reset as a plain
Boolean flag, which happens to be "1" and happens to match the value
of DIFF_INDEX_CACHED.

We switched the function interface for fsck callbacks in a1aad71601
(fsck.h: use "enum object_type" instead of "int", 2021-03-28). However,
we accidentally flipped the type back to "int" as part of 0b4e9013f1
(fsck: mark unused parameters in various fsck callbacks, 2023-07-03).
The mistake happened because that commit was written before a1aad71601
and rebased forward, and I screwed up while resolving the conflict.
Curiously, the compiler does not warn about this mismatch, at least not
when using gcc and clang on Linux (nor in any of our CI environments).
Based on 28abf260a5 (builtin/fsck.c: don't conflate "int" and "enum" in
callback, 2021-06-01), I'd guess that this would cause the AIX xlc
compiler to complain. I noticed because clang-18's UBSan now identifies
mis-matched function calls at runtime, and does complain of this case
when running the test suite.
I'm not entirely clear on whether this mismatch is a problem in
practice. Compilers are certainly free to make enums smaller than "int"
if they don't need the bits, but I suspect that they have to promote
back to int for function calls (though I didn't dig in the standard, and
I won't be surprised if I'm simply wrong and the real-world impact would
depend on the ABI).
Regardless, switching it back to enum is obviously the right thing to do
here; the switch to "int" was simply a mistake.

If both directories D1 and D2 already exists, and further there is a
filesystem entity D2/D1, "git mv D1 D2" would fail, and we get an
error message that says:
"cannot move directory over file, source=D1, destination=D2/D1"
regardless of the type of existing "D2/D1". If it is a file, the
message is correct, but if it is a directory, it is not (we could
make the D2/D1 directory a union of its original contents and what
was in D1/, but that is not what we do).
The code that decies to issue the error message only checks for
existence of "D2/D1" and does not care what kind of thing sits at
the path.
Rephrase the message to say
"destination already exists, source=D1, destination=D2/D1"
that would be suitable for any kind of thing being in the way.

When running 'git maintenance start', the current pattern is to
configure global config settings to enable maintenance on the current
repository and set 'maintenance.auto' to false and _then_ to set up the
schedule with the system scheduler.
This has a problematic error condition: if the scheduler fails to
initialize, the repository still will not use automatic maintenance due
to the 'maintenance.auto' setting.
Fix this gap by swapping the order of operations. If Git fails to
initialize maintenance, then the config changes should never happen.

The 'git maintenance run' command prevents concurrent runs in the same
repository using a 'maintenance.lock' file. However, when using systemd
the hourly maintenance runs the same time as the daily and weekly runs.
(Similarly, daily maintenance runs at the same time as weekly
maintenance.) These competing commands result in some maintenance not
actually being run.
This overlap was something we could not fix until we made the recent
change to not use the builting 'hourly', 'daily', and 'weekly' schedules
in systemd. We can adjust the schedules such that:
1. Hourly runs avoid the 0th hour.
2. Daily runs avoid Monday.
This will keep maintenance runs from colliding when using systemd.

The get_random_minute() method was created to allow maintenance
schedules to be fixed to a random minute of the hour. This randomness is
only intended to spread out the load from a number of clients, but each
client should have an hour between each maintenance cycle.
Add this random minute to the systemd integration.
This integration is more complicated than similar changes for other
schedulers because of a neat trick that systemd allows: templating.
The previous implementation generated two template files with names
of the form 'git-maintenance@.(timer|service)'. The '.timer' or
'.service' indicates that this is a template that is picked up when we
later specify '...@<schedule>.timer' or '...@<schedule>.service'. The
'<schedule>' string is then used to insert into the template both the
'OnCalendar' schedule setting and the '--schedule' parameter of the
'git maintenance run' command.
In order to set these schedules to a given minute, we can no longer use
the 'hourly', 'daily', or 'weekly' strings for '<schedule>' and instead
need to abandon the template model for the .timer files. We can still
use templates for the .service files. For this reason, we split these
writes into two methods.
Modify the template with a custom schedule in the 'OnCalendar' setting.
This schedule has some interesting differences from cron-like patterns,
but is relatively easy to figure out from context. The one that might be
confusing is that '*-*-*' is a date-based pattern, but this must be
omitted when using 'Mon' to signal that we care about the day of the
week. Monday is used since that matches the day used for the 'weekly'
schedule used previously.
Now that the timer files are not templates, we might want to abandon the
'@' symbol in the file names. However, this would cause users with
existing schedules to get two competing schedules due to different
names. The work to remove the old schedule name is one thing that we can
avoid by keeping the '@' symbol in our unit names. Since we are locked
into this name, it makes sense that we keep the template model for the
.service files.
The rest of the change involves making sure we are writing these .timer
and .service files before initializing the schedule with 'systemctl' and
deleting the files when we are done. Some changes are also made to share
the random minute along with a single computation of the execution path
of the current Git executable.
In addition, older Git versions may have written a
'git-maintenance@.timer' template file. Be sure to remove this when
successfully enabling maintenance (or disabling maintenance).

The systemd_timer_write_unit_templates() method writes a single template
that is then used to start the hourly, daily, and weekly schedules with
systemd.
However, in order to schedule systemd maintenance on a given minute,
these templates need to be replaced with specific schedules for each of
these jobs.
Before modifying the schedules, move the writing method above the
systemd_timer_enable_unit() method, so we can write a specific schedule
for each unit.
The diff is computed smaller by showing systemd_timer_enable_unit() and
systemd_timer_delete_units() move instead of
systemd_timer_write_unit_templates() and
systemd_timer_delete_unit_templates().

When we initially created background maintenance -- with its hourly,
daily, and weekly schedules -- we considered the effects of all clients
launching fetches to the server every hour on the hour. The worry of
DDoSing server hosts was noted, but left as something we would consider
for a future update.
As background maintenance has gained more adoption over the past three
years, our worries about DDoSing the big Git hosts has been unfounded.
Those systems, especially those serving public repositories, are already
resilient to thundering herds of much smaller scale.
However, sometimes organizations spin up specific custom server
infrastructure either in addition to or on top of their Git host. Some
of these technologies are built for a different range of scale, and can
hit concurrency limits sooner. Organizations with such custom
infrastructures are more likely to recommend tools like `scalar` which
furthers their adoption of background maintenance.
To help solve for this, create get_random_minute() as a method to help
Git select a random minute when creating schedules in the future. The
integrations with this method do not yet exist, but will follow in
future changes.
To avoid multiple sources of randomness in the Git codebase, create a
new helper function, git_rand(), that returns a random uint32_t. This is
similar to how rand() returns a random nonnegative value, except it is
based on csprng_bytes() which is cryptographic and will return values
larger than RAND_MAX.
One thing that is important for testability is that we notice when we
are under a test scenario and return a predictable result. The schedules
themselves are not checked for this value, but at least one launchctl
test checks that we do not unnecessarily reboot the schedule if it has
not changed from a previous version.

The `pack_geometry` struct is used to maintain and partition a list of
packfiles into a "frozen" set (to be left alone), and a non-frozen set
(to be combined into a single new pack). In the previous commit, we
removed a leak caused by neglecting to free() the heap allocated space
used to store the structure itself.
But there is no need for this structure to live on the heap anyway.
Instead, let's move it to be stack allocated, eliminating the
possibility of a direct leak like the one addressed in the previous
patch.
The one minor hitch is that we use the NULL-ness of the pack_geometry's
struct pointer to determine whether or not we are performing a geometric
repack with `--geometric=<d>`. But since we only initialize the
pack_geometry structure when the `geometric_factor` is non-zero, we can
use that variable (based on whether or not it is equal to zero) to
determine whether or not we are performing a geometric repack.
There are a couple of spots that have access to a pointer to the
pack_geometry struct, but not the geometric_factor itself. Instead of
passing in an additional variable, let's make the geometric_factor a
field of the pack_geometry struct.

When moving a directory onto another with `git mv` various checks are
performed. One of of these validates that the destination is not existing.
When calling `lstat` on the destination path and it fails as the path
doesn't exist, some environments seem to overwrite the passed in
`stat` memory nonetheless (I observed this issue on debian 12 of x86_64,
running on OrbStack on ARM, emulated with Rosetta).
This would affect the code that followed as it would still acccess a now
modified `st` structure, which now seems to contain uninitialized memory.
`S_ISDIR(st_dir_mode)` would then typically return false causing the code
to run into a bad case.
The fix avoids overwriting the existing `st` structure, providing an
alternative that exists only for that purpose.

When the program is ending, we call clear_pack_geometry() to free any
resources in the pack_geometry struct. But the struct itself is
allocated on the heap, and leak-checkers will complain about the
resulting small leak.
This one was marked by Coverity as a "new" leak, though it has existed
since 0fabafd0b9 (builtin/repack.c: add '--geometric' option,
2021-02-22). This might be because recent unrelated changes in the file
confused it about what is new and what is not. But regardless, it is
worth addressing.
We can fix it easily by free-ing the struct. We'll convert our "clear"
function to "free", since the allocation happens in the matching init()
function (though since there is only one call to each, and the struct is
local to this file, it's mostly academic).
Another option would be to put the struct on the stack rather than the
heap. However, this gets tricky, as we check the pointer against NULL in
several places to decide whether we're in geometric mode.

Mark-up unused parameters in the code so that we can eventually
enable -Wunused-parameter by default.
* jk/unused-parameter:
t/helper: mark unused callback void data parameters
tag: mark unused parameters in each_tag_name_fn callbacks
rev-parse: mark unused parameter in for_each_abbrev callback
replace: mark unused parameter in each_mergetag_fn callback
replace: mark unused parameter in ref callback
merge-tree: mark unused parameter in traverse callback
fsck: mark unused parameters in various fsck callbacks
revisions: drop unused "opt" parameter in "tweak" callbacks
count-objects: mark unused parameter in alternates callback
am: mark unused keep_cr parameters
http-push: mark unused parameter in xml callback
http: mark unused parameters in curl callbacks
do_for_each_ref_helper(): mark unused repository parameter
test-ref-store: drop unimplemented reflog-expire command

Help newbies by suggesting that there are cases where force-pushing
is a valid and sensible thing to update a branch at a remote
repository, rather than reconciling with merge/rebase.
* ah/advise-force-pushing:
push: don't imply that integration is always required before pushing
remote: don't imply that integration is always required before pushing
wt-status: don't show divergence advice when committing

Enumerating refs in the packed-refs file, while excluding refs that
match certain patterns, has been optimized.
* tb/refs-exclusion-and-packed-refs:
ls-refs.c: avoid enumerating hidden refs where possible
upload-pack.c: avoid enumerating hidden refs where possible
builtin/receive-pack.c: avoid enumerating hidden references
refs.h: implement `hidden_refs_to_excludes()`
refs.h: let `for_each_namespaced_ref()` take excluded patterns
revision.h: store hidden refs in a `strvec`
refs/packed-backend.c: add trace2 counters for jump list
refs/packed-backend.c: implement jump lists to avoid excluded pattern(s)
refs/packed-backend.c: refactor `find_reference_location()`
refs: plumb `exclude_patterns` argument throughout
builtin/for-each-ref.c: add `--exclude` option
ref-filter.c: parameterize match functions over patterns
ref-filter: add `ref_filter_clear()`
ref-filter: clear reachable list pointers after freeing
ref-filter.h: provide `REF_FILTER_INIT`
refs.c: rename `ref_filter`
