We document that you can specify "refs" to ls-remote, but we don't
explain any further than that they are "matched" as patterns. Since this
can be interpreted in a lot of ways, let's clarify that they are
tail-matched globs.
Likewise, let's use the word "patterns" to refer to them consistently,
rather than "refs" (both here and in the quick "-h" help), and mention
more explicitly that only one pattern needs to be matched (though there
is also an example already that shows this in action).

they're smushed together with no extra whitespace. Let's add some blank

Likewise, the first example uses "./." to refer to the path of the

Commit 7550424804 ("name-rev: include taggerdate in considering the best
name", 2016-04-22) introduced the idea of using taggerdate in the
criteria for selecting the best name. At the time, a certain commit in
linux.git -- namely, aed06b9cfcab -- was being named by name-rev as
v4.6-rc1~9^2~792
which, while correct, was very suboptimal. Some investigation found
that tweaking the MERGE_TRAVERSAL_WEIGHT to lower it could give
alternate answers such as
v3.13-rc7~9^2~14^2~42
or
v3.13~5^2~4^2~2^2~1^2~42
A manual solution involving looking at tagger dates came up with
v3.13-rc1~65^2^2~42
which is much nicer. That workaround was then implemented in name-rev.
Unfortunately, the taggerdate heuristic is causing bugs. I was pointed
to a case in a private repository where name-rev reports a name of the
form
v2022.10.02~86
when users expected to see one of the form
v2022.10.01~2
(I've modified the names and numbers a bit from the real testcase.) As
you can probably guess, v2022.10.01 was created after v2022.10.02 (by a
few hours), even though it pointed to an older commit. While the
condition is unusual even in the repository in question, it is not the
only problematic set of tags in that repository. The taggerdate logic
is causing problems.
Further, it turns out that this taggerdate heuristic isn't even helping
anymore. Due to the fix to naming logic in 3656f84278 ("name-rev:
prefer shorter names over following merges", 2021-12-04), we get
improved names without the taggerdate heuristic. For the original
commit of interest in linux.git, a modern git without the taggerdate
heuristic still provides the same optimal answer of interest, namely:
v3.13-rc1~65^2^2~42
So, the taggerdate is no longer providing benefit, and it is causing
problems. Simply get rid of it.
However, note that "taggerdate" as a variable is used to store things
besides a taggerdate these days. Ever since commit ef1e74065c
("name-rev: favor describing with tags and use committer date to
tiebreak", 2017-03-29), this has been used to store committer dates and
there it is used as a fallback tiebreaker (as opposed to a primary
criteria overriding effective distance calculations). We do not want to
remove that fallback tiebreaker, so not all instances of "taggerdate"
are removed in this change.

A new kind of class was added in Java 17 -- sealed classes.[1] This
feature includes several new keywords that may appear in a declaration
of a class. New modifiers before name of the class: "sealed" and
"non-sealed", and a clause after name of the class marked by keyword
"permits".
The current set of regular expressions in userdiff.c already allows the
modifier "sealed" and the "permits" clause, but not the modifier
"non-sealed", which is the first hyphenated keyword in Java.[2] Allow
hyphen in the words that precede the name of type to match the
"non-sealed" modifier.
In new input file "java-sealed" for the test t4018-diff-funcname.sh, use
a Java code comment for the marker "RIGHT". This workaround is needed,
because the name of the sealed class appears on the line of code that
has the "ChangeMe" marker.

A new kind of class was added in Java 16 -- records.[1] The syntax of
records is similar to regular classes with one important distinction:
the name of the record class is followed by a mandatory list of
components. The list is enclosed in parentheses, it may be empty, and
it may immediately follow the name of the class or type parameters, if
any, with or without separating whitespace. For example:
public record Example(int i, String s) {
}
public record WithTypeParameters<A, B>(A a, B b, String s) {
}
record SpaceBeforeComponents (String comp1, int comp2) {
}
Support records in the builtin userdiff pattern for Java. Add "record"
to the alternatives of keywords for kinds of class.
Allowing matching various possibilities for the type parameters and/or
list of the components of a record has already been covered by the
preceding patch.

A class or interface in Java can have type parameters following the name
in the declared type, surrounded by angle brackets (paired less than and
greater than signs).[2] The type parameters -- `A` and `B` in the
examples -- may follow the class name immediately:
public class ParameterizedClass<A, B> {
}
or may be separated by whitespace:
public class SpaceBeforeTypeParameters <A, B> {
}
A part of the builtin userdiff pattern for Java matches declarations of
classes, enums, and interfaces. The regular expression requires at
least one whitespace character after the name of the declared type.
This disallows matching for opening angle bracket of type parameters
immediately after the name of the type. Mandatory whitespace after the
name of the type also disallows using the pattern in repositories with a
fairly common code style that puts braces for the body of a class on
separate lines:
class WithLineBreakBeforeOpeningBrace
{
}
Support matching Java code in more diverse code styles and declarations
of classes and interfaces with type parameters immediately following the
name of the type in the builtin userdiff pattern for Java. Do so by
just matching anything until the end of the line after the keywords for
the kind of type being declared.

While it makes sense not to inherit stdin from the parent process to
avoid deadlocking, it's not necessary to completely ban stdin to
children. An informed user should be able to configure stdin safely. By
setting `some_child.process.no_stdin=1` before calling `get_next_task()`
we provide a reasonable default behavior but enable users to set up
stdin streaming for themselves during the callback.
`some_child.process.stdout_to_stderr`, however, remains unmodifiable by
`get_next_task()` - the rest of the run_processes_parallel() API depends

Make the replay_opts_release() function added in the preceding commit
non-static, and use it for freeing the "struct replay_opts"
constructed for "rebase" and "revert".
To safely call our new replay_opts_release() we'll need to stop
calling it in sequencer_remove_state(), and instead call it where we
allocate the "struct replay_opts" itself.
This is because in e.g. do_interactive_rebase() we construct a "struct
replay_opts" with "get_replay_opts()", and then call
"complete_action()". If we get far enough in that function without
encountering errors we'll call "pick_commits()" which (indirectly)
calls sequencer_remove_state() at the end.
But if we encounter errors anywhere along the way we'd punt out early,
and not free() the memory we allocated. Remembering whether we
previously called sequencer_remove_state() would be a hassle.
Using a FREE_AND_NULL() pattern would also work, as it would be safe
to call replay_opts_release() repeatedly. But let's fix this properly
instead, by having the owner of the data free() it.

"pattern_list", but we should be freeing another member of the same
type, which we'll do in the subsequent commit.
Let's also replace the "return" if we don't have an
"opt->pattern_expression" with a conditional call of
free_pattern_expr().
Before db84376f98 (grep.c: remove "extended" in favor of
"pattern_expression", fix segfault, 2022-10-11) the pattern here was:
if (!x)
return;
free_pattern_expr(y);
While at it, instead of:
if (!x)
return;
free_pattern_expr(x);
Let's instead do:
if (x)
free_pattern_expr(x);
This will make it easier to free additional members from
free_grep_patterns() in the future.

Plug a memory leak introduced in [1], since that change didn't follow
the "goto done" pattern introduced in [2] we'd leak the "&buf" memory.

Follow-up 465028e0e2 (merge: add missing strbuf_release(),
2021-10-07) and address the "msg" memory leak in this block. We could
free "&msg" before the "goto done" here, but even better is to avoid
allocating it in the first place.
By repeating the "Fast-forward" string here we can avoid using a
"struct strbuf" altogether.
