e5cb1e3f09 t4053: avoid writing to unopened pipe
This fixes an occasional hang I see when running t4053 with
--verbose-log using dash.

Commit 1e3f26542a (diff --no-index: support reading from named pipes,
2023-07-05) added a test that "diff --no-index" will complain when
comparing a named pipe and a directory. The minimum we need to test this
is to mkfifo the pipe, and then run "git diff --no-index pipe some_dir".
But the test does one thing more: it spawns a background shell process
that opens the pipe for writing, like this:

        {
                (>pipe) &
        } &&

This extra writer _could_ be useful if Git misbehaves and tries to open
the pipe for reading. Without the writer, Git would block indefinitely
and the test would never end. But since we do not have such a bug, Git
does not open the pipe and it is the writing process which will block
indefinitely, since there are no readers. The test addresses this by
running "kill $!" in a test_when_finished block. Since the writer should
be blocking forever, this kill command will reliably find it waiting.

However, this seems to be somewhat racy, in that the writing process
sometimes hangs around even after the "kill". In a normal run of the
test script without options, this doesn't have any effect; the
main test script completes anyway. But with --verbose-log, we spawn a
"tee" process that reads the script output, and it won't end until all
descriptors pointing to its input pipe are closed. And the background
process that is hanging around still has its stderr, etc, pointed into
that pipe.

You can reproduce the situation like this:

  cd t
  ./t4053-diff-no-index.sh --verbose-log --stress

Let that run for a few minutes, and then you'll find that some of the
runs have hung. For example, at 11:53, I ran:

  $ ps xk start o pid,start,command | grep tee | head
   713459 11:48:06 tee -a /home/peff/compile/git/t/test-results/t4053-diff-no-index.stress-9.out

   728117 11:48:08 tee -a /home/peff/compile/git/t/test-results/t4053-diff-no-index.stress-5.out
   738738 11:48:09 tee -a /home/peff/compile/git/t/test-results/t4053-diff-no-index.stress-31.out
   739457 11:48:09 tee -a /home/peff/compile/git/t/test-results/t4053-diff-no-index.stress-27.out
   744432 11:48:10 tee -a /home/peff/compile/git/t/test-results/t4053-diff-no-index.stress-21.out
   744471 11:48:10 tee -a /home/peff/compile/git/t/test-results/t4053-diff-no-index.stress-29.out
   761961 11:48:12 tee -a /home/peff/compile/git/t/test-results/t4053-diff-no-index.stress-0.out
   812299 11:48:19 tee -a /home/peff/compile/git/t/test-results/t4053-diff-no-index.stress-8.out

All of these have been hung for several minutes. We can investigate one
and see that it's waiting to get EOF on its input:

  $ strace -p 713459
  strace: Process 713459 attached
  read(0,
  ^C

Who else has that descriptor open?

  $ lsof -a -p 713459 -d 0 +E

It's a shell, presumably a subshell spawned by the main script. Though
it may seem odd, having the same descriptor open several times is not
unreasonable (they're all basically the original stdout/stderr of the
script that has been copied). And they should all close when the process
exits. So what's it doing? Curiously, it will exit as soon as we strace
it:

  $ strace -s 64 -p 719203
  strace: Process 719203 attached
  openat(AT_FDCWD, "pipe", O_WRONLY|O_CREAT|O_TRUNC, 0666) = -1 ENOENT (No such file or directory)
  write(2, "./t4053-diff-no-index.sh: 7: eval: ", 35) = 35
  write(2, "cannot create pipe: Directory nonexistent", 41) = 41
  write(2, "\n", 1)                       = 1
  exit_group(2)                           = ?
  +++ exited with 2 +++

I think what happens is this:

  - it is blocking in the openat() call for the pipe, as we expect (so
    this is definitely the backgrounded subshell mentioned above)

  - strace sends signals (probably STOP/CONT); those cause the kernel to
    stop blocking, but libc will restart the system call automatically

  - by this time, the "pipe" fifo is gone, so we'll actually try to
    create a regular file. But of course the surrounding directory is
    gone, too! So we get ENOENT, and then exit as normal.

So the blocking is something we expect to happen. But what we didn't
expect is for the process to still exist at all! It should have been
killed earlier when the parent process called "kill", but it wasn't. And
we can't catch the race at this point, because it happened much earlier.

One can guess, though, that there is some race with the shell setting up
the signal handling in the backgrounded subshell, and possibly blocking
or ignoring signals at the time that the "kill" is received.  Curiously,
the race does not seem to happen if I use "bash" instead of "dash", so
presumably bash's setup here is more atomic.

One fix might be to try killing the subshell more aggressively, either
using SIGKILL, or looping on kill/wait. But that seems complex and
likely to introduce new problems/races. Instead, we can observe that the
writer is not needed at all. Git will notice the pipe via stat() before
it is ever opened. So we can simply drop the writer subshell entirely.

If we ever changed Git to open the path and fstat() it, this would
result in the test hanging. But we're not likely to do that. After all,
we have to stat() paths to see if they are openable at all (e.g., it
could be a directory), so this seems like a low risk. And anybody who
does make such a change will immediately see the issue, as Git would
hang consistently.

69ecfcacfd maintenance: update schedule before config
When running 'git maintenance start', the current pattern is to
configure global config settings to enable maintenance on the current
repository and set 'maintenance.auto' to false and _then_ to set up the
schedule with the system scheduler.

This has a problematic error condition: if the scheduler fails to
initialize, the repository still will not use automatic maintenance due
to the 'maintenance.auto' setting.

Fix this gap by swapping the order of operations. If Git fails to
initialize maintenance, then the config changes should never happen.

daa787010c maintenance: use random minute in systemd scheduler
The get_random_minute() method was created to allow maintenance
schedules to be fixed to a random minute of the hour. This randomness is
only intended to spread out the load from a number of clients, but each
client should have an hour between each maintenance cycle.

Add this random minute to the systemd integration.

This integration is more complicated than similar changes for other
schedulers because of a neat trick that systemd allows: templating.

The previous implementation generated two template files with names
of the form 'git-maintenance@.(timer|service)'. The '.timer' or
'.service' indicates that this is a template that is picked up when we
later specify '...@<schedule>.timer' or '...@<schedule>.service'. The
'<schedule>' string is then used to insert into the template both the
'OnCalendar' schedule setting and the '--schedule' parameter of the
'git maintenance run' command.

In order to set these schedules to a given minute, we can no longer use
the 'hourly', 'daily', or 'weekly' strings for '<schedule>' and instead
need to abandon the template model for the .timer files. We can still
use templates for the .service files. For this reason, we split these
writes into two methods.

Modify the template with a custom schedule in the 'OnCalendar' setting.
This schedule has some interesting differences from cron-like patterns,
but is relatively easy to figure out from context. The one that might be
confusing is that '*-*-*' is a date-based pattern, but this must be
omitted when using 'Mon' to signal that we care about the day of the
week. Monday is used since that matches the day used for the 'weekly'
schedule used previously.

Now that the timer files are not templates, we might want to abandon the
'@' symbol in the file names. However, this would cause users with
existing schedules to get two competing schedules due to different
names. The work to remove the old schedule name is one thing that we can
avoid by keeping the '@' symbol in our unit names. Since we are locked
into this name, it makes sense that we keep the template model for the
.service files.

The rest of the change involves making sure we are writing these .timer
and .service files before initializing the schedule with 'systemctl' and
deleting the files when we are done. Some changes are also made to share
the random minute along with a single computation of the execution path
of the current Git executable.

In addition, older Git versions may have written a
'git-maintenance@.timer' template file. Be sure to remove this when
successfully enabling maintenance (or disabling maintenance).

231e86c10c t4053: avoid race when killing background processes
The test 'diff --no-index reads from pipes' starts a couple of
background processes that write to the pipes that are passed to "diff
--no-index". If the test passes then we expect these processes to exit
as all their output will have been read. However if the test fails
then we want to make sure they do not hang about on the users machine
and the test remembers they should be killed by calling

      test_when_finished  "! kill $!"

after each background process is created. Unfortunately there is a
race where test_when_finished may run before the background process
exits even when all its output has been read resulting in the kill
command succeeding which causes the test to fail. Fix this by ignoring
the exit status of the kill command. If the diff is successful we
could instead wait for the background process to exit and check their
status but that feels like it is testing the platform's printf
implementation rather than git's code.

72695d8214 mv: handle lstat() failure correctly
When moving a directory onto another with `git mv` various checks are
performed. One of of these validates that the destination is not existing.

When calling `lstat` on the destination path and it fails as the path
doesn't exist, some environments seem to overwrite the passed  in
`stat` memory nonetheless (I observed this issue on debian 12 of x86_64,
running on OrbStack on ARM, emulated with Rosetta).

This would affect the code that followed as it would still acccess a now
modified `st` structure, which now seems to contain uninitialized memory.
`S_ISDIR(st_dir_mode)` would then typically return false causing the code
to run into a bad case.

The fix avoids overwriting the existing `st` structure, providing an
alternative that exists only for that purpose.

Note that this patch minimizes complexity instead of stack-frame size.

c016726c2d send-email: avoid creating more than one Term::ReadLine object
Every time git-send-email calls its ask() function to prompt the user,
we call term(), which instantiates a new Term::ReadLine object. But in
v1.46 of Term::ReadLine::Gnu (which provides the Term::ReadLine
interface on some platforms), its constructor refuses to create a second
instance[1]. So on systems with that version of the module, most
git-send-email instances will fail (as we usually prompt for both "to"
and "in-reply-to" unless the user provided them on the command line).

We can fix this by keeping a single instance variable and returning it
for each call to term(). In perl 5.10 and up, we could do that with a
"state" variable. But since we only require 5.008, we'll do it the
old-fashioned way, with a lexical "my" in its own scope.

Note that the tests in t9001 detect this problem as-is, since the
failure mode is for the program to die. But let's also beef up the
"Prompting works" test to check that it correctly handles multiple
inputs (if we had chosen to keep our FakeTerm hack in the previous
commit, then the failure mode would be incorrectly ignoring prompts
after the first).

2a409a1d12 parse-options: no --[no-]no-...
Avoid showing an optional "no-" for options that already start with a
"no-" in the short help, as that double negation is confusing.  Document
the opposite variant on its own line with a generated help text instead,
unless it's defined and documented explicitly already.

e8e5d294dc parse-options: show negatability of options in short help
Add a "[no-]" prefix to options without the flag PARSE_OPT_NONEG to
document the fact that you can negate them.

This looks a bit strange for options that already start with "no-", e.g.
for the option --no-name of git show-branch:

    --[no-]no-name        suppress naming strings

You can actually use --no-no-name as an alias of --name, so the short
help is not wrong.  If we strip off any of the "no-"s, we lose either
the ability to see if the remaining one belongs to the documented
variant or to see if it can be negated.

8dcb49021e t1502: move optionspec help output to a file
"git rev-parse --parseopt" shows the short help with its description of
all recognized options twice: When called with -h or --help, and after
reporting an unknown option.  Move the one for optionspec into a file
and use it in two tests to deduplicate that part.

"git rev-parse --parseopt -- --h" wraps the help text in "cat <<\EOF"
and "EOF".  Keep that part in the file to use it as is in the test that
needs it and simply remove it in the other one using sed.

Disable whitespace checking for the file using an attribute, as we need
to keep its spaces intact and wouldn't want a stray --whitespace=fix
turn them into tabs.

6ce7afe163 rebase --skip: fix commit message clean up when skipping squash
During a series of "fixup" and/or "squash" commands, the interactive
rebase accumulates a commit message from all the commits that are being
squashed together. If one of the commits has conflicts when it is picked
and the user chooses to skip that commit then we need to remove that
commit's message from accumulated messages.  To do this 15ef69314d
(rebase --skip: clean up commit message after a failed fixup/squash,
2018-04-27) updated commit_staged_changes() to reset the accumulated
message to the commit message of HEAD (which does not contain the
message from the skipped commit) when the last command was "fixup" or
"squash" and there are no staged changes. Unfortunately the code to do
this contains two bugs.

(1) If parse_head() fails we pass an invalid pointer to
    unuse_commit_buffer().

(2) The reconstructed message uses the entire commit buffer from HEAD
    including the headers, rather than just the commit message.

The first issue is fixed by splitting up the "if" condition into several
statements each with its own error handling. The second issue is fixed
by finding the start of the commit message within the commit buffer
using find_commit_subject().

The existing test added by 15ef69314d is modified to show the effect of
this bug.  The bug is triggered when skipping the first command in the
chain (as the test does before this commit) but the effect is hidden
because opts->current_fixup_count is set to zero which leads
update_squash_messages() to recreate the squash message file from
scratch overwriting the bad message created by
commit_staged_changes(). The test is also updated to explicitly check
the commit messages rather than relying on grep to ensure they do not
contain any stray commit headers.

To check the commit message the function test_commit_message() is moved
from t3437-rebase-fixup-options.sh to test-lib.sh. As the function is
now publicly available it is updated to provide better error detection
and avoid overwriting the commonly used files "actual" and "expect".
Support for reading the expected commit message from stdin is also
added.

1c04cb0744 ident: don't consider '.' a crud
When we process a user's name (as in user.name), we strip all
leading and trailing crud from it.  Right now, we consider a dot
a crud character, and strip it off.

However, this is unsuitable for many personal names because humans
frequently have abbreviated suffixes, such as "Jr." or "Sr." at the end
of their names, and this corrupts them.  Some other users may wish to
use an abbreviated name or initial, which will pose a problem especially
in cultures that write the family name first, followed by the personal
name.

Since the current approach causes lots of practical problems, let's
avoid it by no longer considering a dot to be crud.

Note that "." in the name forces the entire name to be quoted to
please mailers, but stripping "." only at the beginning and the end
does not help a name with "." in the middle (like "brian m. carlson")
so this change will not make it much worse.  A name like "Given
Family, Jr." that did not have to be quoted now would need to be, in
order to be placed on the e-mail headers, though.

This is based on a weather-balloon patch by Jeff King sent in Aug 2021

d089a06421 bundle: use OPT_PASSTHRU_ARGV
"git bundle" passes the progress control options to "git pack-objects"
by parsing and then recreating them explicitly.  Simplify that process
by using OPT_PASSTHRU_ARGV instead.

This also fixes --no-quiet, which has been doing the same as --quiet
since its introduction by 79862b6b77 (bundle-create: progress output
control, 2019-11-10) because it had been defined using OPT_SET_INT with
a value of 0, which sets 0 when negated as well.
