Christian Couder 9b96046b92 gc: add gc.repackFilterTo config option
A previous commit implemented the `gc.repackFilter` config option
to specify a filter that should be used by `git gc` when
performing repacks.

Another previous commit has implemented
`git repack --filter-to=<dir>` to specify the location of the
packfile containing filtered out objects when using a filter.

Let's implement the `gc.repackFilterTo` config option to specify
that location in the config when `gc.repackFilter` is used.

Now when `git gc` will perform a repack with a <dir> configured
through this option and not empty, the repack process will be
passed a corresponding `--filter-to=<dir>` argument.

Christian Couder 71c5aec1f5 repack: implement --filter-to for storing filtered out objects
A previous commit has implemented `git repack --filter=<filter-spec>` to
allow users to filter out some objects from the main pack and move them
into a new different pack.

It would be nice if this new different pack could be created in a
different directory than the regular pack. This would make it possible
to move large blobs into a pack on a different kind of storage, for
example cheaper storage.

Even in a different directory, this pack can be accessible if, for
example, the Git alternates mechanism is used to point to it. In fact
not using the Git alternates mechanism can corrupt a repo as the
generated pack containing the filtered objects might not be accessible
from the repo any more. So setting up the Git alternates mechanism
should be done before using this feature if the user wants the repo to
be fully usable while this feature is used.

In some cases, like when a repo has just been cloned or when there is no
other activity in the repo, it's Ok to setup the Git alternates
mechanism afterwards though. It's also Ok to just inspect the generated
packfile containing the filtered objects and then just move it into the
'.git/objects/pack/' directory manually. That's why it's not necessary
for this command to check that the Git alternates mechanism has been
already setup.

While at it, as an example to show that `--filter` and `--filter-to`
work well with other options, let's also add a test to check that these
options work well with `--max-pack-size`.

Christian Couder 1cd43a9ed9 gc: add gc.repackFilter config option
A previous commit has implemented `git repack --filter=<filter-spec>` to
allow users to filter out some objects from the main pack and move them
into a new different pack.

Users might want to perform such a cleanup regularly at the same time as
they perform other repacks and cleanups, so as part of `git gc`.

Let's allow them to configure a <filter-spec> for that purpose using a
new gc.repackFilter config option.

Now when `git gc` will perform a repack with a <filter-spec> configured
through this option and not empty, the repack process will be passed a
corresponding `--filter=<filter-spec>` argument.

Christian Couder 48a9b67b43 repack: add --filter=<filter-spec> option
This new option puts the objects specified by `<filter-spec>` into a
separate packfile.

This could be useful if, for example, some blobs take up a lot of
precious space on fast storage while they are rarely accessed. It could
make sense to move them into a separate cheaper, though slower, storage.

It's possible to find which new packfile contains the filtered out
objects using one of the following:

  - `git verify-pack -v ...`,
  - `test-tool find-pack ...`, which a previous commit added,
  - `--filter-to=<dir>`, which a following commit will add to specify
    where the pack containing the filtered out objects will be.

This feature is implemented by running `git pack-objects` twice in a
row. The first command is run with `--filter=<filter-spec>`, using the
specified filter. It packs objects while omitting the objects specified
by the filter. Then another `git pack-objects` command is launched using
`--stdin-packs`. We pass it all the previously existing packs into its
stdin, so that it will pack all the objects in the previously existing
packs. But we also pass into its stdin, the pack created by the previous
`git pack-objects --filter=<filter-spec>` command as well as the kept
packs, all prefixed with '^', so that the objects in these packs will be
omitted from the resulting pack. The result is that only the objects
filtered out by the first `git pack-objects` command are in the pack
resulting from the second `git pack-objects` command.

As the interactions with kept packs are a bit tricky, a few related
tests are added.

Christian Couder 6cfcabfb9f pack-objects: allow --filter without --stdout
9535ce7337 (pack-objects: add list-objects filtering, 2017-11-21)
taught `git pack-objects` to use `--filter`, but required the use of
`--stdout` since a partial clone mechanism was not yet in place to
handle missing objects. Since then, changes like 9e27beaa23
(promisor-remote: implement promisor_remote_get_direct(), 2019-06-25)
and others added support to dynamically fetch objects that were missing.

Even without a promisor remote, filtering out objects can also be useful
if we can put the filtered out objects in a separate pack, and in this
case it also makes sense for pack-objects to write the packfile directly
to an actual file rather than on stdout.

Remove the `--stdout` requirement when using `--filter`, so that in a
follow-up commit, repack can pass `--filter` to pack-objects to omit
certain objects from the resulting packfile.

Kousik Sanagavarapu a3d2e83a17 ref-filter: add mailmap support
Add mailmap support to ref-filter formats which are similar in
pretty. This support is such that the following pretty placeholders are
equivalent to the new ref-filter atoms:

	%aN = authorname:mailmap
	%cN = committername:mailmap

	%aE = authoremail:mailmap
	%aL = authoremail:mailmap,localpart
	%cE = committeremail:mailmap
	%cL = committeremail:mailmap,localpart

Additionally, mailmap can also be used with ":trim" option for email by
doing something like "authoremail:mailmap,trim".

The above also applies for the "tagger" atom, that is,
"taggername:mailmap", "taggeremail:mailmap", "taggeremail:mailmap,trim"
and "taggername:mailmap,localpart".

The functionality of ":trim" and ":localpart" remains the same. That is,
":trim" gives the email, but without the angle brackets and ":localpart"
gives the part of the email before the '@' character (if such a
character is not found then we directly grab everything between the
angle brackets).

Patrick Steinhardt f97c8b1e00 revision: make pseudo-opt flags read via stdin behave consistently
When reading revisions from stdin via git-rev-list(1)'s `--stdin` option
then these revisions never honor flags like `--not` which have been
passed on the command line. Thus, an invocation like e.g. `git rev-list
--all --not --stdin` will not treat all revisions read from stdin as
uninteresting. While this behaviour may be surprising to a user, it's
been this way ever since it has been introduced via 42cabc341c (Teach
rev-list an option to read revs from the standard input., 2006-09-05).

With that said, in c40f0b7877 (revision: handle pseudo-opts in `--stdin`
mode, 2023-06-15) we have introduced a new mode to read pseudo opts from
standard input where this behaviour is a lot more confusing. If you pass
`--not` via stdin, it will:

    - Influence subsequent revisions or pseudo-options passed on the
      command line.

    - Influence pseudo-options passed via standard input.

    - _Not_ influence normal revisions passed via standard input.

This behaviour is extremely inconsistent and bound to cause confusion.

While it would be nice to retroactively change the behaviour for how
`--not` and `--stdin` behave together, chances are quite high that this
would break existing scripts that expect the current behaviour that has
been around for many years by now. This is thus not really a viable
option to explore to fix the inconsistency.

Instead, we change the behaviour of how pseudo-opts read via standard
input influence the flags such that the effect is fully localized. With
this change, when reading `--not` via standard input, it will:

    - _Not_ influence subsequent revisions or pseudo-options passed on
      the command line, which is a change in behaviour.

    - Influence pseudo-options passed via standard input.

    - Influence normal revisions passed via standard input, which is a
      change in behaviour.

Thus, all flags read via standard input are fully self-contained to that
standard input, only.

While this is a breaking change as well, the behaviour has only been
recently introduced with Git v2.42.0. Furthermore, the current behaviour
can be regarded as a simple bug. With that in mind it feels like the
right thing to retroactively change it and make the behaviour sane.

Kristoffer Haugsbakk 2e0d30d928 range-diff: treat notes like log
Currently, `range-diff` shows the default notes if no notes-related
arguments are given. This is also how `log` behaves. But unlike
`range-diff`, `log` does *not* show the default notes if
`--notes=<custom>` are given. In other words, this:

    git log --notes=custom

is equivalent to this:

    git log --no-notes --notes=custom

While:

    git range-diff --notes=custom

acts like this:

    git log --notes --notes-custom

This can’t be how the user expects `range-diff` to behave given that the
man page for `range-diff` under `--[no-]notes[=<ref>]` says:

> This flag is passed to the `git log` program (see git-log(1)) that
> generates the patches.

This behavior also affects `format-patch` since it uses `range-diff` for
the cover letter. Unlike `log`, though, `format-patch` is not supposed
to show the default notes if no notes-related arguments are given.[1]
But this promise is broken when the range-diff happens to have something
to say about the changes to the default notes, since that will be shown
in the cover letter.

Remedy this by introducing `--show-notes-by-default` that `range-diff` can
use to tell the `log` subprocess what to do.

Dragan Simic bd48adc31d diff --stat: add config option to limit filename width
Add new configuration option diff.statNameWidth=<width> that is equivalent
to the command-line option --stat-name-width=<width>, but it is ignored
by format-patch.  This follows the logic established by the already
existing configuration option diff.statGraphWidth=<width>.

Limiting the widths of names and graphs in the --stat output makes sense
for interactive work on wide terminals with many columns, hence the support
for these configuration options.  They don't affect format-patch because
it already adheres to the traditional 80-column standard.

Update the documentation and add more tests to cover new configuration
option diff.statNameWidth=<width>.  While there, perform a few minor code
and whitespace cleanups here and there, as spotted.

Junio C Hamano 764b2330db update-index doc: v4 is OK with JGit and libgit2
Being invented in late 2012 no longer makes the index v4 format
"relatively young".

The support for the index version 4 was added to libgit2 with their
5625d86b (index: support index v4, 2016-05-17) and to JGit with
their e9cb0a8e (DirCache: support index V4, 2020-08-10).

Let's update the paragraph that discouraged its use for folks overly
cautious about cross-tool compatibility.

Linus Arver 6ccbc66794 trailer doc: <token> is a <key> or <keyAlias>, not both
The `--trailer` option takes a "<token>=<value>" argument, for example

    --trailer "Acked-by=Bob"

And in this exampple it is understood that "Acked-by" is the <token>.
However, the user can use a shorter "ack" string by defining
configuration like

    git config trailer.ack.key "Acked-by"

However, in the docs we define the above configuration as

    trailer.<token>.key

so the <token> can mean either the longer "Acked-by" or the shorter
"ack".

Separate the two meanings of <token> into <key> and <keyAlias>, and
update the configuration syntax to say "trailer.<keyAlias>.key".

Linus Arver db97296122 trailer doc: emphasize the effect of configuration variables
The sentence does not mention the effect of configuration variables at
all, when they are actively used by default (unless --parse is
specified) to potentially add new trailers, without the user having to
always supply --trailer manually.

Linus Arver 289a0b2447 trailer --unfold help: prefer "reformat" over "join"
The phrase "join whitespace-continued values" requires some additional
context. For example, "whitespace" means newlines (not just space
characters), and "join" means to join only the multiple lines together
for a single trailer (and not that we are joining multiple trailers
together). That is, "join" means to convert

    token: This is a very long value, with spaces and
      newlines in it.

to

    token: This is a very long value, with spaces and newlines in it.

and does not mean to convert

    token: value1
    token: value2

to

    token: value1 value2.

Update the help text to resolve the above ambiguity. While we're add it,
update the docs to use similar language as the change in the help text.

Linus Arver cb088cbe0f trailer --parse docs: add explanation for its usefulness
For users who are skimming the docs to go straight to the individual
breakdown of each flag, it may not be clear why --parse is a convenience
alias (without them also looking at the other options that --parse turns
on). To save them the trouble of looking at the other options (and
computing what that would mean), describe a summary of the overall
effect.

Similarly update the area when we first mention --parse near the top of
the doc.
