We've never documented the fact that a client can provide multiple
ref-prefix capabilities. Let's describe the behavior.
We also never discussed the "best effort" nature of the prefixes. The
client side of git.git has always treated them this way, filtering the
result with local patterns. And indeed any client must do this, because
the prefix patterns are not sufficient to express the usual refspecs
(and so for "foo" we ask for "refs/heads/foo", "refs/tags/foo", and so
on).
So this may be considered a change in the spec with respect to client
expectations / requirements, but it's mostly codifying existing
behavior.

While 'git version' is probably the least complex git command,
it is a non-experimental user-facing builtin command. As such
it should have a help page.
Both `git help` and `git version` can be called as options
(`--help`/`--version`) that internally get converted to the
corresponding command. Add a small paragraph to
Documentation/git.txt describing how these two options
interact with each other and link to this help page for the
sub-options that `--version` can take. Well, currently there
is only one sub-option, but that could potentially increase
in future versions of Git.

As was noted in 1a85b49b87a (parse-options: make OPT_ARGUMENT() more
useful, 2019-03-14) there's only ever been one user of the
OPT_ARGUMENT(), that user was added in 20de316e334 (difftool: allow
running outside Git worktrees with --no-index, 2019-03-14).
The OPT_ARGUMENT() feature itself was added way back in
580d5bffdea (parse-options: new option type to treat an option-like
parameter as an argument., 2008-03-02), but as discussed in
1a85b49b87a wasn't used until 20de316e334 in 2019.
Now that the preceding commit has migrated this code over to using
"struct strvec" to manage the "args" member of a "struct
child_process", we can just use that directly instead of relying on
OPT_ARGUMENT.
This has a minor change in behavior in that if we'll pass --no-index
we'll now always pass it as the first argument, before we'd pass it in
whatever position the caller did. Preserving this was the real value
of OPT_ARGUMENT(), but as it turns out we didn't need that either. We
can always inject it as the first argument, the other end will parse
it just the same.
Note that we cannot remove the "out" and "cpidx" members of "struct
parse_opt_ctx_t" added in 580d5bffdea, while they were introduced with
OPT_ARGUMENT() we since used them for other things.

that am --abort would return the user to a clean state. However, since
am, unlike rebase, is intended to be used within a dirty working tree,
--abort will only clean the files involved in the am operation.

We recently added tips for server admins to configure various transports
to support v2's GIT_PROTOCOL variable. While the protocol-v2 document is
pretty technical and not of interest to most admins, it may be a
starting point for them to figure out how to turn on v2. Let's put some
pointers from there to the other documentation.

The v2 protocol requires that the GIT_PROTOCOL environment variable gets
passed around, but we don't have any documentation describing how this
is supposed to work. In particular, we need to note what server admins
might need to configure to make things work.
The definition of the GIT_PROTOCOL variable is probably the best place
for this, since:
- we deal with multiple transports (ssh, http, etc).
Transport-specific documentation (like the git-http-backend bits
added in the previous commit) are helpful for those transports, but
this gives a broader overview. Plus we do not have a specific
transport endpoint program for ssh, so this is a reasonable place to
mention it.
- the server side of the protocol involves multiple programs. For now,
upload-pack is the only endpoint which uses GIT_PROTOCOL, but that
will likely expand in the future. We're better off with a central
discussion of what the server admin might need to do. However, for
discoverability, this patch adds a pointer from upload-pack's
documentation.

Historically there was a little bit of configuration needed at the
webserver level in order to get the client's v2 protocol probes to Git.
But when we introduced the v2 protocol, we never documented these.
As of the previous commit, this should mostly work out of the box
without any explicit configuration. But it's worth documenting this to
make it clear how we expect it to work, especially in the face of
webservers which don't provide all headers over the CGI interface. Or
anybody who runs across this documentation but has an older version of
Git (or _used_ to have an older version, and wonders why they still have
a SetEnvIf line in their Apache config and whether it's still
necessary).

When changing the scope of a sparse-checkout using cone mode, we might
have some tracked directories go out of scope. The current logic removes
the tracked files from within those directories, but leaves the ignored
files within those directories. This is a bit unexpected to users who
have given input to Git saying they don't need those directories
anymore.
This is something that is new to the cone mode pattern type: the user
has explicitly said "I want these directories and _not_ those
directories." The typical sparse-checkout patterns more generally apply
to "I want files with with these patterns" so it is natural to leave
ignored files as they are. This focus on directories in cone mode
provides us an opportunity to change the behavior.
Leaving these ignored files in the sparse directories makes it
impossible to gain performance benefits in the sparse index. When we
track into these directories, we need to know if the files are ignored
or not, which might depend on the _tracked_ .gitignore file(s) within
the sparse directory. This depends on the indexed version of the file,
so the sparse directory must be expanded.
We must take special care to look for untracked, non-ignored files in
these directories before deleting them. We do not want to delete any
meaningful work that the users were doing in those directories and
perhaps forgot to add and commit before switching sparse-checkout
definitions. Since those untracked files might be code files that
generated ignored build output, also do not delete any ignored files
from these directories in that case. The users can recover their state
by resetting their sparse-checkout definition to include that directory
and continue. Alternatively, they can see the warning that is presented
and delete the directory themselves to regain the performance they
expect.
By deleting the sparse directories when changing scope (or running 'git
sparse-checkout reapply') we regain these performance benefits as if the
repository was in a clean state.
Since these ignored files are frequently build output or helper files
from IDEs, the users should not need the files now that the tracked
files are removed. If the tracked files reappear, then they will have
newer timestamps than the build artifacts, so the artifacts will need to
be regenerated anyway.
Use the sparse-index as a data structure in order to find the sparse
directories that can be safely deleted. Re-expand the index to a full
one if it was full before.

The "unbundle" command added in 2e0afafebd8 (Add git-bundle: move
objects and references by archive, 2007-02-22) did not show progress
output, even though the underlying API learned how to show progress in
be042aff24c (Teach progress eye-candy to fetch_refs_from_bundle(),
2011-09-18).
Now we'll show "Unbundling objects" using the new --progress-title
option to "git index-pack", to go with its existing "Receiving
objects" and "Indexing objects" (which it shows when invoked with
"--stdin", and with a pack file, respectively).
Unlike "git bundle create" we don't handle "--quiet" here, nor
"--all-progress" and "--all-progress-implied". Those are all specific
to "create" (and "verify", in the case of "--quiet").
The structure of the existing documentation is a bit unclear, e.g. the
documentation for the "--quiet" option added in
79862b6b77c (bundle-create: progress output control, 2019-11-10) only
describes how it works for "create", and not for "verify". That and
other issues in it should be fixed, but I'd like to avoid untangling
that mess right now. Let's just support the standard "--no-progress"
implicitly here, and leave cleaning up the general behavior of "git
bundle" for a later change.

Add a --progress-title option to index-pack, when data is piped into
index-pack its progress is a proxy for whatever's feeding it data.
This option will allow us to set a more relevant progress bar title in
"git bundle unbundle", and is also used in my "bundle-uri" RFC
patches[1] by a new caller in fetch-pack.c.
The code change in cmd_index_pack() won't handle
"--progress-title=xyz", only "--progress-title xyz", and the "(i+1)"
style (as opposed to "i + 1") is a bit odd.
Not using the "--long-option=value" style is inconsistent with
existing long options handled by cmd_index_pack(), but makes the code
that needs to call it better (two strvec_push(), instead of needing a
strvec_pushf()). Since the option is internal-only the inconsistency
shouldn't matter.
I'm copying the pattern to handle it as-is from the handling of the
existing "-o" option in the same function, see 9cf6d3357aa (Add
git-index-pack utility, 2005-10-12) for its addition. That's a short
option, but the code to implement the two is the same in functionality
and style. Eventually we'd like to migrate all of this this to
parse_options(), which would make these differences in behavior go
away.

The existing mechanism for scheduling background maintenance is done
through cron. On Linux systems managed by systemd, systemd provides an
alternative to schedule recurring tasks: systemd timers.
The main motivations to implement systemd timers in addition to cron
are:
* cron is optional and Linux systems running systemd might not have it
installed.
* The execution of `crontab -l` can tell us if cron is installed but not
if the daemon is actually running.
* With systemd, each service is run in its own cgroup and its logs are
tagged by the service inside journald. With cron, all scheduled tasks
are running in the cron daemon cgroup and all the logs of the
user-scheduled tasks are pretended to belong to the system cron
service.
Concretely, a user that doesn’t have access to the system logs won’t
have access to the log of their own tasks scheduled by cron whereas
they will have access to the log of their own tasks scheduled by
systemd timer.
Although `cron` attempts to send email, that email may go unseen by
the user because these days, local mailboxes are not heavily used
anymore.
In order to schedule git maintenance, we need two unit template files:
* ~/.config/systemd/user/git-maintenance@.service
to define the command to be started by systemd and
* ~/.config/systemd/user/git-maintenance@.timer
to define the schedule at which the command should be run.
Those units are templates that are parameterized by the frequency.
Based on those templates, 3 timers are started:
* git-maintenance@hourly.timer
* git-maintenance@daily.timer
* git-maintenance@weekly.timer
The command launched by those three timers are the same as with the
other scheduling methods:
/path/to/git for-each-repo --exec-path=/path/to
--config=maintenance.repo maintenance run --schedule=%i
with the full path for git to ensure that the version of git launched
for the scheduled maintenance is the same as the one used to run
`maintenance start`.
The timer unit contains `Persistent=true` so that, if the computer is
powered down when a maintenance task should run, the task will be run
when the computer is back powered on.

Depending on the system, different schedulers can be used to schedule
the hourly, daily and weekly executions of `git maintenance run`:
* `launchctl` for MacOS,
* `schtasks` for Windows and
* `crontab` for everything else.
`git maintenance run` now has an option to let the end-user explicitly
choose which scheduler he wants to use:
`--scheduler=auto|crontab|launchctl|schtasks`.
When `git maintenance start --scheduler=XXX` is run, it not only
registers `git maintenance run` tasks in the scheduler XXX, it also
removes the `git maintenance run` tasks from all the other schedulers to
ensure we cannot have two schedulers launching concurrent identical
tasks.
The default value is `auto` which chooses a suitable scheduler for the
system.
`git maintenance stop` doesn't have any `--scheduler` parameter because
this command will try to remove the `git maintenance run` tasks from all
the available schedulers.

Write multi-pack bitmaps in the format described by
Documentation/technical/bitmap-format.txt, inferring their presence with
the absence of '--bitmap'.
To write a multi-pack bitmap, this patch attempts to reuse as much of
the existing machinery from pack-objects as possible. Specifically, the
MIDX code prepares a packing_data struct that pretends as if a single
packfile has been generated containing all of the objects contained
within the MIDX.

Opening multiple instance of the same MIDX can lead to problems like two
separate packed_git structures which represent the same pack being added
to the repository's object store.
The above scenario can happen because prepare_midx_pack() checks if
`m->packs[pack_int_id]` is NULL in order to determine if a pack has been
opened and installed in the repository before. But a caller can
construct two copies of the same MIDX by calling get_multi_pack_index()
and load_multi_pack_index() since the former manipulates the
object store directly but the latter is a lower-level routine which
allocates a new MIDX for each call.
So if prepare_midx_pack() is called on multiple MIDXs with the same
pack_int_id, then that pack will be installed twice in the object
store's packed_git pointer.
This can lead to problems in, for e.g., the pack-bitmap code, which does
something like the following (in pack-bitmap.c:open_pack_bitmap()):
struct bitmap_index *bitmap_git = ...;
for (p = get_all_packs(r); p; p = p->next) {
if (open_pack_bitmap_1(bitmap_git, p) == 0)
ret = 0;
}
which is a problem if two copies of the same pack exist in the
packed_git list because pack-bitmap.c:open_pack_bitmap_1() contains a
conditional like the following:
if (bitmap_git->pack || bitmap_git->midx) {
/* ignore extra bitmap file; we can only handle one */
warning("ignoring extra bitmap file: %s", packfile->pack_name);
close(fd);
return -1;
}
Avoid this scenario by not letting write_midx_internal() open a MIDX
that isn't also pointed at by the object store. So long as this is the
case, other routines should prefer to open MIDXs with
get_multi_pack_index() or reprepare_packed_git() instead of creating
instances on their own. Because get_multi_pack_index() returns
`r->object_store->multi_pack_index` if it is non-NULL, we'll only have
one instance of a MIDX open at one time, avoiding these problems.
To encourage this, drop the `struct multi_pack_index *` parameter from
`write_midx_internal()`, and rely instead on the `object_dir` to find
(or initialize) the correct MIDX instance.
Likewise, replace the call to `close_midx()` with
`close_object_store()`, since we're about to replace the MIDX with a new
one and should invalidate the object store's memory of any MIDX that
might have existed beforehand.
Note that this now forbids passing object directories that don't belong
to alternate repositories over `--object-dir`, since before we would
have happily opened a MIDX in any directory, but now restrict ourselves
to only those reachable by `r->objects->multi_pack_index` (and alternate
MIDXs that we can see by walking the `next` pointer).
As far as I can tell, supporting arbitrary directories with
`--object-dir` was a historical accident, since even the documentation
says `<alt>` when referring to the value passed to this option.

The soon-to-be-implemented multi-pack bitmap treats object in the first
bit position specially by assuming that all objects in the pack it was
selected from are also represented from that pack in the MIDX. In other
words, the pack from which the first object was selected must also have
all of its other objects selected from that same pack in the MIDX in
case of any duplicates.
But this assumption relies on the fact that there is at least one object
in that pack to begin with; otherwise the object in the first bit
position isn't from a preferred pack, in which case we can no longer
assume that all objects in that pack were also selected from the same
pack.
Guard this assumption by checking the number of objects in the given
preferred pack, and failing if the given pack is empty.
To make sure we can safely perform this check, open any packs which are
contained in an existing MIDX via prepare_midx_pack(). The same is done
for new packs via the add_pack_to_midx() callback, but packs picked up
from a previous MIDX will not yet have these opened.
