PHP permits functions to be defined like
final public function foo() { }
abstract protected function bar() { }
but our hunk header pattern does not recognize these decorations.
Add "final" and "abstract" to the list of function modifiers.

Way back in f9b8908b (commit.c: use generation numbers for
in_merge_bases(), 2018-05-01), a heuristic was used to short-circuit
the in_merge_bases() walk. This works just fine as long as the
caller is checking only two commits, but when there are multiple,
there is a possibility that this heuristic is _very wrong_.
Some code moves since then has changed this method to
repo_in_merge_bases_many() inside commit-reach.c. The heuristic
computes the minimum generation number of the "reference" list, then
compares this number to the generation number of the "commit".
In a recent topic, a test was added that used in_merge_bases_many()
to test if a commit was reachable from a number of commits pulled
from a reflog. However, this highlighted the problem: if any of the
reference commits have a smaller generation number than the given
commit, then the walk is skipped _even if there exist some with
higher generation number_.
This heuristic is wrong! It must check the MAXIMUM generation number
of the reference commits, not the MINIMUM.
This highlights a testing gap. t6600-test-reach.sh covers many
methods in commit-reach.c, including in_merge_bases() and
get_merge_bases_many(), but since these methods either restrict to
two input commits or actually look for the full list of merge bases,
they don't check this heuristic!
Add a possible input to "test-tool reach" that tests
in_merge_bases_many() and add tests to t6600-test-reach.sh that
cover this heuristic. This includes cases for the reference commits
having generation above and below the generation of the input commit,
but also having maximum generation below the generation of the input
commit.
The fix itself is to swap min_generation with a max_generation in
repo_in_merge_bases_many().

The format.useAutoBase configuration option exists to allow users to
enable '--base=auto' for format-patch by default.
This can sometimes lead to poor workflow, due to unexpected failures
when attempting to format an ancient patch:
$ git format-patch -1 <an old commit>
fatal: base commit shouldn't be in revision list
This can be very confusing, as it is not necessarily immediately obvious
that the user requested a --base (since this was in the configuration,
not on the command line).
We do want --base=auto to fail when it cannot provide a suitable base,
as it would be equally confusing if a formatted patch did not include
the base information when it was requested.
Teach format.useAutoBase a new mode, "whenAble". This mode will cause
format-patch to attempt to include a base commit when it can. However,
if no valid base commit can be found, then format-patch will continue
formatting the patch without a base commit.
In order to avoid making yet another branch name unusable with --base,
do not teach --base=whenAble or --base=whenable.
Instead, refactor the base_commit option to use a callback, and rely on
the global configuration variable auto_base.
This does mean that a user cannot request this optional base commit
generation from the command line. However, this is likely not too
valuable. If the user requests base information manually, they will be
immediately informed of the failure to acquire a suitable base commit.
This allows the user to make an informed choice about whether to
continue the format.
Add tests to cover the new mode of operation for --base.

Commands such as
$ git pull --rebase --recurse-submodules --quiet
produce non-quiet output from the merge or rebase. Pass the --quiet
option down when invoking "rebase" and "merge".
Also fix the parsing of git submodule update -v.
When e84c3cf3 (git-submodule.sh: accept verbose flag in cmd_update
to be non-quiet, 2018-08-14) taught "git submodule update" to take
"--quiet", it apparently did not know how ${GIT_QUIET:+--quiet}
works, and reviewers seem to have missed that setting the variable
to "0", rather than unsetting it, still results in "--quiet" being
passed to underlying commands.

Both fetch and push support pattern refspecs which allow fetching or
pushing references that match a specific pattern. Because these patterns
are globs, they have somewhat limited ability to express more complex
situations.
For example, suppose you wish to fetch all branches from a remote except
for a specific one. To allow this, you must setup a set of refspecs
which match only the branches you want. Because refspecs are either
explicit name matches, or simple globs, many patterns cannot be
expressed.
Add support for a new type of refspec, referred to as "negative"
refspecs. These are prefixed with a '^' and mean "exclude any ref
matching this refspec". They can only have one "side" which always
refers to the source. During a fetch, this refers to the name of the ref
on the remote. During a push, this refers to the name of the ref on the
local side.
With negative refspecs, users can express more complex patterns. For
example:
git fetch origin refs/heads/*:refs/remotes/origin/* ^refs/heads/dontwant
will fetch all branches on origin into remotes/origin, but will exclude
fetching the branch named dontwant.
Refspecs today are commutative, meaning that order doesn't expressly
matter. Rather than forcing an implied order, negative refspecs will
always be applied last. That is, in order to match, a ref must match at
least one positive refspec, and match none of the negative refspecs.
This is similar to how negative pathspecs work.

When doing combined diffs, we have two possible code paths:
- a slower one which independently diffs against each parent, applies
any filters, and then intersects the resulting paths
- a faster one which walks all trees simultaneously
When the diff options specify that we must do certain filters, like
pickaxe, then we always use the slow path, since the pickaxe code only
knows how to handle filepairs, not the n-parent entries generated for
combined diffs.
But there are two problems with the slow path:
1. It's slow. Running:
git rev-list HEAD | git diff-tree --stdin -r -c
in git.git takes ~3s on my machine. But adding "--find-object" to
that increases it to ~6s, even though find-object itself should
incur only a few extra oid comparisons. On linux.git, it's even
worse: 35s versus 215s.
2. It doesn't catch all cases where a particular path is interesting.
Consider a merge with parent blobs X and Y for a particular path,
and end result Z. That should be interesting according to "-c",
because the result doesn't match either parent. And it should be
interesting even with "--find-object=X", because "X" went away in
the merge.
But because we perform each pairwise diff independently, this
confuses the intersection code. The change from X to Z is still
interesting according to --find-object. But in the other parent we
went from Y to Z, so the diff appears empty! That causes the
intersection code to think that parent didn't change the path, and
thus it's not interesting for "-c".
This patch fixes both by implementing --find-object for the multitree
code. It's a bit unfortunate that we have to duplicate some logic from
diffcore-pickaxe, but this is the best we can do for now. In an ideal
world, all of the diffcore code would stop thinking about filepairs and
start thinking about n-parent sets, and we could use the multitree walk
with all of it.
Until then, there are some leftover warts:
- other pickaxe operations, like -S or -G, still suffer from both
problems. These would be hard to adapt because they rely on having
a diff_filespec() for each path to look at content. And we'd need to
define what an n-way "change" means in each case (probably easy for
"-S", which can compare counts, but not so clear for -G, which is
about grepping diffs).
- other options besides --find-object may cause us to use the slow
pairwise path, in which case we'll go back to producing a different
(wrong) answer for the X/Y/Z case above.
We may be able to hack around these, but I think the ultimate solution
will be a larger rewrite of the diffcore code. For now, this patch
improves one specific case but leaves the rest.

Many functions take an argv/argc pair, but never actually look at argc.
This makes it useless at best (we use the NULL sentinel in argv to find
the end of the array), and misleading at worst (what happens if the argc
count does not match the argv NULL?).
In each of these instances, the argv NULL does match the argc count, so
there are no bugs here. But let's tighten the interfaces to make it
harder to get wrong (and to reduce some -Wunused-parameter complaints).

When a fetch with the --filter argument is made, the configured default
filter is set even if one already exists. This change was made in
5e46139376 ("builtin/fetch: remove unique promisor remote limitation",
2019-06-25) - in particular, changing from:
* If this is the FIRST partial-fetch request, we enable partial
* on this repo and remember the given filter-spec as the default
* for subsequent fetches to this remote.
to:
* If this is a partial-fetch request, we enable partial on
* this repo if not already enabled and remember the given
* filter-spec as the default for subsequent fetches to this
* remote.
(The given filter-spec is "remembered" even if there is already an
existing one.)
This is problematic whenever a lazy fetch is made, because lazy fetches
are made using "git fetch --filter=blob:none", but this will also happen
if the user invokes "git fetch --filter=<filter>" manually. Therefore,
restore the behavior prior to 5e46139376, which writes a filter-spec
only if the current fetch request is the first partial-fetch one (for
that remote).

Now that shortlog supports reading from trailers, it can be useful to
combine counts from multiple trailers, or between trailers and authors.
This can be done manually by post-processing the output from multiple
runs, but it's non-trivial to make sure that each name/commit pair is
counted only once.
This patch teaches shortlog to accept multiple --group options on the
command line, and pull data from all of them. That makes it possible to
run:
git shortlog -ns --group=author --group=trailer:co-authored-by
to get a shortlog that counts authors and co-authors equally.
The implementation is mostly straightforward. The "group" enum becomes a
bitfield, and the trailer key becomes a list. I didn't bother
implementing the multi-group semantics for reading from stdin. It would
be possible to do, but the existing matching code makes it awkward, and
I doubt anybody cares.
The duplicate suppression we used for trailers now covers authors and
committers as well (though in non-trailer single-group mode we can skip
the hash insertion and lookup, since we only see one value per commit).
There is one subtlety: we now care about the case when no group bit is
set (in which case we default to showing the author). The caller in
builtin/log.c needs to be adapted to ask explicitly for authors, rather
than relying on shortlog_init(). It would be possible with some
gymnastics to make this keep working as-is, but it's not worth it for a
single caller.

Trailers don't necessarily contain name/email identity values, so
shortlog has so far treated them as opaque strings. However, since many
trailers do contain identities, it's useful to treat them as such when
they can be parsed. That lets "-e" work as usual, as well as mailmap.
When they can't be parsed, we'll continue with the old behavior of
treating them as a single string (there's no new test for that here,
since the existing tests cover a trailer like this).

The current documentation is vague about what happens with
--group=trailer:signed-off-by when we see a commit with:
Signed-off-by: One
Signed-off-by: Two
Signed-off-by: One
We clearly should credit both "One" and "Two", but should "One" get
credited twice? The current code does so, but mostly because that was
the easiest thing to do. It's probably more useful to count each commit
at most once. This will become especially important when we allow
values from multiple sources in a future patch.

format to see things like who has helped whom:

In preparation for adding more grouping types, let's refactor the
committer/author grouping code and add a user-facing option that binds
them together. In particular:
- the main option is now "--group", to make it clear
that the various group types are mutually exclusive. The
"--committer" option is an alias for "--group=committer".
- we keep an enum rather than a binary flag, to prepare
for more values
- we prefer switch statements to ternary assignment, since
other group types will need more custom code

non-inclusive term, so let's avoid using it here.
Since three of the touched test cases make use of the fact that two of

even with the same two letters), we choose to replace the use of

The term `master` has a loaded history that serves as a constant
reminder of racial injustice. The Git project has no desire to
perpetuate this and already started avoiding it.
The test suite uses variations of this name for branches other than the
default one. Apart from t3200, where we just addressed this in the
previous commit, those instances can be renamed in an automated manner
because they do not require any changes outside of the test script, so
let's do that.
Seeing as the touched branches have very little (if anything) to do with
the default branch, we choose to use a completely separate naming
scheme: `topic_<number>` (it cannot be `topic-<number>` because t5515
uses the `test_oid` machinery with the term, and that machinery uses
shell variables internally, whose names cannot contain dashes).
This trick was performed by this (GNU) sed invocation:
$ sed -i 's/master\([a-z0-9]\)/topic_\1/g' t/t*.sh

Because these constructs can be used to parse user input to be
passed to rev-list --objects, e.g.
range=$(git rev-parse v1.0..v2.0) &&
git rev-list --objects $range | git pack-objects --stdin
the endpoints (v1.0 and v2.0 in the example) are shown without
peeling them to underlying commits, even when they are annotated
tags. Make sure it stays that way.
While at it, ensure "rev-parse A...B" also keeps the endpoints A and
B unpeeled, even though the negative side (i.e. the merge-base
between A and B) has to become a commit.

- die "$(eval_gettext "'\$arg' does not appear to be a valid revision")"
- break
- }
- revs="$revs $rev"
into:

+ if (get_oid(commit_id, &oid) && has_double_dash)
+ die(_("'%s' does not appear to be a valid "
+ "revision"), arg);
+
+ string_list_append(&revs, oid_to_hex(&oid));
+ free(commit_id);
In case of an invalid "arg" when "has_double_dash" is false, the old
code would "break" out of the argument loop.
In the new C code though, `oid_to_hex(&oid)` is unconditonally
appended to "revs". This is wrong first because "oid" is junk as
`get_oid(commit_id, &oid)` failed and second because it doesn't break
out of the argument loop.
Not breaking out of the argument loop means that "arg" is then not
treated as a path restriction (which is wrong).

If a user is cloning a SHA-1 repository with GIT_DEFAULT_HASH set to
"sha256", then we can end up with a repository where the repository
format version is 0 but the extensions.objectformat key is set to
"sha256". This is both wrong (the user has a SHA-1 repository) and
nonfunctional (because the extension cannot be used in a v0 repository).
This happens because in a clone, we initially set up the repository, and
then change its algorithm based on what the remote side tells us it's
using. We've initially set up the repository as SHA-256 in this case,
and then later on reset the repository version without clearing the
extension.
We could just always set the extension in this case, but that would mean
that our SHA-1 repositories weren't compatible with older Git versions,
even though there's no reason why they shouldn't be. And we also don't
want to initialize the repository as SHA-1 initially, since that means
if we're cloning an empty repository, we'll have failed to honor the
GIT_DEFAULT_HASH variable and will end up with a SHA-1 repository, not a
SHA-256 repository.
Neither of those are appealing, so let's tell the repository
initialization code if we're doing a reinit like this, and if so, to
clear the extension if we're using SHA-1. This makes sure we produce a
valid and functional repository and doesn't break any of our other use
cases.

To avoid branch names with a loaded history, we already started to avoid
using the name "master" in a couple instances.
The `t3200-branch.sh` script uses variations of this name for branches
other than the default one. So let's change those names, as
"lowest-hanging fruits" in the effort to use more inclusive naming
throughout Git's source code. While at it, make those branch names
independent from the default branch name.
In this particular instance, this rename requires a couple of
non-trivial adjustments, as the aligned output depends on the maximum
length of the displayed branches (which we now changed), and also on the
alphabetical order (which we now changed, too).

In the ongoing effort to make the Git project a more inclusive place,
let's try to avoid names like "master" where possible.
In this instance, the use of the term `slave` is unfortunately enshrined
in IO::Pty's API. We simply cannot avoid using that word here. But at
least we can get rid of the usage of the word `master` and hope that
IO::Pty will be eventually adjusted, too.
Guessing that IO::Pty might follow Python's lead, we replace the name
`master` by `parent` (hoping that IO::Pty will adopt the parent/child
nomenclature, too).
