When we know we're going to show the subject or body of a tag or commit,
we call find_subpos(), which returns pointers and lengths for the three
parts: subject, body, signature.
Oddly, the function finds the signature twice: once by calling
parse_signature() at the start, which copies the signature into a
separate strbuf, and then again by calling parse_signed_buffer() after
we've parsed past the subject.
This is due to 482c119186 (gpg-interface: improve interface for parsing
tags, 2021-02-11) and 88bce0e24c (ref-filter: hoist signature parsing,
2021-02-11). The idea is that in a multi-hash world, tag signatures may
appear in the header, rather than at the end of the body, in which case
we need to extract them into a separate buffer.
But parse_signature() would never find such a buffer! It only looks for
signature lines (like "-----BEGIN PGP") at the start of each line,
without any header keyword. So this code will never find anything except
the usual in-body signature.
And the extra code has two downsides:
1. We spend time copying the payload and signature into strbufs. That
might even be useful if we ended up with a NUL-terminated copy of
the payload data, but we throw it away immediately. And the
signature, since it comes at the end of the message, is already its
own NUL-terminated buffer.
The overhead isn't huge, but I measured a pretty consistent 1-2%
speedup running "git for-each-ref --format='%(subject)'" with this
patch on a clone of linux.git.
2. The output of find_subpos() is a set of three ptr/len combinations,
but only two of them point into the original buffer. This makes the
interface confusing: you can't do pointer comparisons between them,
and you have to remember to free the signature buffer. Since
there's only one caller, it's not too bad in practice, but it did
bite me while working on the next patch (and simplifying it will
pave the way for that).
In the long run we might have to go back to something like this
approach, if we do have multi-hash header signatures. But I would argue
that the extra buffer should kick in only for a header signature, and be
passed out of find_subpos() separately.

We don't usually include newlines in test titles, because you get funny
TAP output like:
ok 417 - show good signature with custom format
ok 418 - show good signature with custom format
with ssh
ok 419 - signature atom with grade option and bad signature
where a TAP parser would ignore the extra line anyway, giving the wrong
title. This comes from 26c9c03f0a (ref-filter: add new "signature" atom,
2023-06-04), and I think it was probably just editor line wrapping.
I checked for other cases with:

In the current stack tests, ref records are compared for equality
by sometimes using the dedicated function for ref-record comparison,
reftable_ref_record_equal(), and sometimes by explicity comparing
contents of the ref records.
The latter method is undesired because there can exist unequal ref
records with some of the contents being equal. Replace the latter
instances of ref-record comparison with the former. This has the
added benefit of preserving uniformity throughout the test file.

If neither HAVE_DEV_TTY nor GIT_WINDOWS_NATIVE is set, while compiling
the 'compat/terminal.c' code, then the fallback code calls the system
getpass() function. Unfortunately, this ignores the 'echo' parameter of
the git_terminal_prompt() function, since it has no way to implement that
functionality. This results in a less than optimal user experience on
cygwin, which does not define either of those build flags.
However, cygwin does have a functional '/dev/tty', so that it can build
with HAVE_DEV_TTY and benefit from the improved user experience.
The improved git_terminal_prompt() function that comes with HAVE_DEV_TTY
is used in the git_prompt() function, which in turn is used by the
'git credential', 'git bisect' and 'git help' commands. In addition to
git_terminal_prompt(), read_key_without_echo() is likewise improved and
used by the 'git add -p' command.
While using the 'git credential fill' command, for example:
$ printf "%s\n" protocol=https host=example.com path=git | ./git credential fill
Username for 'https://example.com': user
Password for 'https://user@example.com':
protocol=https
host=example.com
username=user
password=pass
$
The 'user' name is now echoed while typing (the password isn't), where this
wasn't the case before.
When using the auto-correct feature:
$ ./git -c help.autocorrect=prompt fred
WARNING: You called a Git command named 'fred', which does not exist.
Run 'grep' instead [y/N]? n
$ ./git -c help.autocorrect=prompt fred
WARNING: You called a Git command named 'fred', which does not exist.
Run 'grep' instead [y/N]? y
fatal: no pattern given
$
The user can actually see what they are typing at the prompt. Similar
comments apply to 'git bisect':
$ ./git bisect bad master~1
You need to start by "git bisect start"
Do you want me to do it for you [Y/n]? y
status: waiting for both good and bad commits
status: waiting for good commit(s), bad commit known
$ ./git bisect reset
Already on 'master-tmp'
$
$ ./git bisect start
status: waiting for both good and bad commits
$ ./git bisect bad master~1
status: waiting for good commit(s), bad commit known
$ ./git bisect next
warning: bisecting only with a bad commit
Are you sure [Y/n]? n
$ ./git bisect reset
Already on 'master-tmp'
$
The read_key_without_echo() function leads to a much improved 'git add -p'
command, when the 'interactive.singleKey' configuration is set:
$ cd ..
$ mkdir test-git
$ cd test-git
$ git init -q
$ echo foo >file
$ git add file
$ echo bar >file
$ ../git/git -c interactive.singleKey=true add -p
diff --git a/file b/file
index 257cc56..5716ca5 100644
--- a/file
+++ b/file
@@ -1 +1 @@
-foo
+bar
(1/1) Stage this hunk [y,n,q,a,d,e,p,?]? y
$
Note that, not only is the user input echoed, but that it is immediately
accepted (without having to type <return>) and the program exits with the
hunk staged (in this case) or not.
In order to reap these benefits, set the HAVE_DEV_TTY build flag in the
cygwin configuration section of config.mak.uname.

Some large repositories use tags to track a huge list of release
versions. While this choice is costly on the ref advertisement, it is
further wasteful for clients who do not need those tags. Allow clients
to optionally skip the tag advertisement.
This behavior is similar to that of 'git clone --no-tags' implemented in
0dab2468ee (clone: add a --no-tags option to clone without tags,
2017-04-26), including the modification of the remote.origin.tagOpt
config value to include "--no-tags".
One thing that is opposite of the 'git clone' implementation is that
this allows '--tags' as an assumed option, which can be naturally negated
with '--no-tags'. The clone command does not accept '--tags' but allows
"--no-no-tags" as the negation of its '--no-tags' option.
While testing this option, combine the test with the previously untested
'--no-src' option introduced in 4527db8ff8 (scalar: add --[no-]src

immediately following the message instead of as a trailer block
separated from the message by a blank line.
For example, if a message's text was exactly "The subject" with no

The subject
my-trailer: true
While it is generally expected that a commit message should end with a

When updating sparse patterns, we open a lock_file to write out the new
data. The lock_file struct holds the file descriptor, but we call
fdopen() to get a stdio handle to do the actual write.
After we finish writing, we fflush() so that all of the data is on disk,
and then call commit_lock_file() which closes the descriptor. But we
never fclose() the stdio handle, leaking it.
The obvious solution seems like it would be to just call fclose(). But
when? If we do it before commit_lock_file(), then the lock_file code is
left thinking it owns the now-closed file descriptor, and will do an
extra close() on the descriptor. But if we do it before, we have the
opposite problem: the lock_file code will close the descriptor, and
fclose() will do the extra close().
We can handle this correctly by using fdopen_lock_file(). That leaves
ownership of the stdio handle with the lock_file, which knows not to
double-close it.
We do have to adjust the code a bit:
- we have to handle errors ourselves; we can just die(), since that's
what xfdopen() would have done (and we can even provide a more
specific error message).
- we no longer need to call fflush(); committing the lock-file
auto-closes it, which will now do the flush for us. As a bonus, this
will actually check that the flush was successful before renaming
the file into place.
- we can get rid of the local "fd" variable, since we never look at it
ourselves now

Our error reporting routines append a trailing newline, and the strings
we pass to them should not include them (otherwise we get an extra blank
line after the message).
These cases were all found by looking at the results of:
git grep -P '[^_](error|error_errno|warning|die|die_errno)\(.*\\n"[,)]' '*.c'
Note that we _do_ sometimes include a newline in the middle of such
messages, to create multiline output (hence our grep matching "," or ")"
after we see the newline, so we know we're at the end of the string).
It's possible that one or more of these cases could intentionally be
including a blank line at the end, but having looked at them all

We're leaking the array of common object IDs in `send_pack()`. Fix this
by creating a common exit path where we free the leaking data. While at
it, unify some other cleanups now that we have a central place to put
them.

We leak both the `nt_object_array` and `negotiator` structures in
`negotiate_using_fetch()`. Plug both of these leaks.
These leaks were exposed by t5516, but fixing them is not sufficient to
make the whole test suite leak free.
