In 7ba7c52d76 (upload-pack: fix race condition in error messages,
2023-08-10), we have fixed a race in t5516-fetch-push.sh where sometimes
error messages got intermingled. This was done by splitting up the call
to `die()` such that we print the error message before writing to the
remote side, followed by a call to `exit(1)` afterwards.
This causes a subtle regression though as `die()` causes us to exit with
exit code 128, whereas we now call `exit(1)`. It's not really clear
whether we want to guarantee any specific error code in this case, and
neither do we document anything like that. But on the other hand, it
seems rather clear that this is an unintended side effect of the change
given that this change in behaviour was not mentioned at all.
Restore the status-quo by exiting with 128. The test in t5703 to
ensure that "git fetch" fails by using test_must_fail, which does
not care between exiting 1 and 128, so this changes will not affect
any test.

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

All of these have been hung for several minutes. We can investigate one

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.

The code that decies to issue the error message only checks for
existence of "D2/D1" and does not care what kind of thing sits at

Rephrase the message to say
"destination already exists, source=D1, destination=D2/D1"

Before this patch, git check-attr was unable to read the attributes from
a .gitattributes file within a sparse directory. The original comment
was operating under the assumption that users are only interested in
files or directories inside the cones. Therefore, in the original code,
in the case of a cone-mode sparse-checkout, we didn't load the
.gitattributes file.
However, this behavior can lead to missing attributes for files inside
sparse directories, causing inconsistencies in file handling.
To resolve this, revise 'git check-attr' to allow attribute reading for
files in sparse directories from the corresponding .gitattributes files:
1.Utilize path_in_cone_mode_sparse_checkout() and index_name_pos_sparse
to check if a path falls within a sparse directory.
2.If path is inside a sparse directory, employ the value of
index_name_pos_sparse() to find the sparse directory containing path and
path relative to sparse directory. Proceed to read attributes from the
tree OID of the sparse directory using read_attr_from_blob().
3.If path is not inside a sparse directory，ensure that attributes are
fetched from the index blob with read_blob_data_from_index().
Change the test 'check-attr with pathspec outside sparse definition' to
'test_expect_success' to reflect that the attributes inside a sparse
directory can now be read. Ensure that the sparse index case works
correctly for git check-attr to illustrate the successful handling of
attributes within sparse directories.

Add tests for `git check-attr`, make sure attribute file does get read

Add a test named 'diff --check with pathspec outside sparse definition'.
It starts by disabling the trailing whitespace and space-before-tab
checks using the core. whitespace configuration option. Then, it
specifically re-enables the trailing whitespace check for a file located
in a sparse directory by adding a whitespace=trailing-space rule to the
.gitattributes file within that directory. Next, create and populate the
folder1 directory, and then add the .gitattributes file to the index.
Edit the contents of folder1/a, add it to the index, and proceed to
"re-sparsify" 'folder1/' with 'git sparse-checkout reapply'. Finally,
use 'git diff --check --cached' to compare the 'index vs. HEAD',
ensuring the correct application of the attribute rules even when the
file's path is outside the sparse-checkout definition.
Mark the two tests 'check-attr with pathspec outside sparse definition'
and 'diff --check with pathspec outside sparse definition' as
'test_expect_failure' to reflect an existing issue where the attributes
inside a sparse directory are ignored. Ensure that the 'check-attr'
command fails to read the required attributes to demonstrate this
expected failure.

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.

the hourly maintenance runs the same time as the daily and weekly runs.
(Similarly, daily maintenance runs at the same time as weekly
maintenance.) These competing commands result in some maintenance not
actually being run.
This overlap was something we could not fix until we made the recent

1. Hourly runs avoid the 0th hour.
2. Daily runs avoid Monday.

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).

The systemd_timer_write_unit_templates() method writes a single template
that is then used to start the hourly, daily, and weekly schedules with
systemd.
However, in order to schedule systemd maintenance on a given minute,
these templates need to be replaced with specific schedules for each of
these jobs.
Before modifying the schedules, move the writing method above the
systemd_timer_enable_unit() method, so we can write a specific schedule
for each unit.
The diff is computed smaller by showing systemd_timer_enable_unit() and
systemd_timer_delete_units() move instead of
systemd_timer_write_unit_templates() and
systemd_timer_delete_unit_templates().

When we initially created background maintenance -- with its hourly,
daily, and weekly schedules -- we considered the effects of all clients
launching fetches to the server every hour on the hour. The worry of
DDoSing server hosts was noted, but left as something we would consider
for a future update.
As background maintenance has gained more adoption over the past three
years, our worries about DDoSing the big Git hosts has been unfounded.
Those systems, especially those serving public repositories, are already
resilient to thundering herds of much smaller scale.
However, sometimes organizations spin up specific custom server
infrastructure either in addition to or on top of their Git host. Some
of these technologies are built for a different range of scale, and can
hit concurrency limits sooner. Organizations with such custom
infrastructures are more likely to recommend tools like `scalar` which
furthers their adoption of background maintenance.
To help solve for this, create get_random_minute() as a method to help
Git select a random minute when creating schedules in the future. The
integrations with this method do not yet exist, but will follow in
future changes.
To avoid multiple sources of randomness in the Git codebase, create a
new helper function, git_rand(), that returns a random uint32_t. This is
similar to how rand() returns a random nonnegative value, except it is
based on csprng_bytes() which is cryptographic and will return values
larger than RAND_MAX.
One thing that is important for testability is that we notice when we
are under a test scenario and return a predictable result. The schedules
themselves are not checked for this value, but at least one launchctl
test checks that we do not unnecessarily reboot the schedule if it has
not changed from a previous version.

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.

Test t5516-fetch-push.sh has a test 'deny fetch unreachable SHA1,
allowtipsha1inwant=true' that checks stderr for a specific error
string from the remote. In some build environments the error sent
over the remote connection gets mingled with the error from the
die() statement. Since both signals are being output to the same
file descriptor (but from parent and child processes), the output
we are matching with grep gets split.
To reduce the risk of this failure, follow this process instead:
1. Write an error message to stderr.
2. Write an error message across the connection.
3. exit(1).
This reorders the events so the error is written entirely before
the client receives a message from the remote, removing the race
condition.

The `pack_geometry` struct is used to maintain and partition a list of
packfiles into a "frozen" set (to be left alone), and a non-frozen set
(to be combined into a single new pack). In the previous commit, we
removed a leak caused by neglecting to free() the heap allocated space
used to store the structure itself.
But there is no need for this structure to live on the heap anyway.
Instead, let's move it to be stack allocated, eliminating the
possibility of a direct leak like the one addressed in the previous
patch.
The one minor hitch is that we use the NULL-ness of the pack_geometry's
struct pointer to determine whether or not we are performing a geometric
repack with `--geometric=<d>`. But since we only initialize the
pack_geometry structure when the `geometric_factor` is non-zero, we can
use that variable (based on whether or not it is equal to zero) to
determine whether or not we are performing a geometric repack.
There are a couple of spots that have access to a pointer to the
pack_geometry struct, but not the geometric_factor itself. Instead of
passing in an additional variable, let's make the geometric_factor a
field of the pack_geometry struct.

We just introduced a helper to avoid showing a console window when the
scheduled task runs `git.exe`. Let's actually use it.

On Windows, there are two kinds of executables, console ones and
non-console ones. Git's executables are all console ones.
When launching the former e.g. in a scheduled task, a CMD window pops
up. This is not what we want for the tasks installed via the `git
maintenance` command.
To work around this, let's introduce `headless-git.exe`, which is a
non-console program that does _not_ pop up any window. All it does is to
re-launch `git.exe`, suppressing that console window, passing through
all command-line arguments as-are.
