When f4dbdfc4d5 (commit-graph: clean up leaked memory during write,
2018-10-03) added the UNLEAK, it was right before a call to die_errno().
e103f7276f (commit-graph: return with errors during write, 2019-06-12)
made it unnecessary, as it was then followed by a free() call for the
allocated string.
The code moved to write_commit_graph_file() in the meantime and the
string pointer is now part of a struct, but the function's only caller
still cleans up the allocation. Drop the superfluous UNLEAK.

git archive checks whether pathspec arguments match anything to avoid
surprises due to typos and later loads the index to get attributes.
This order was OK when these features were introduced by ba053ea96c
(archive: do not read .gitattributes in working directory, 2009-04-18)
and d5f53d6d6f (archive: complain about path specs that don't match
anything, 2009-12-12).
But when attribute matching was added to pathspec in b0db704652
(pathspec: allow querying for attributes, 2017-03-13), the pathspec
checker in git archive did not support it fully, because it lacks the
attributes from the index.
Load the index earlier, before the pathspec check, to support attr
pathspecs.

The diff machinery has two ways to detect changes to set the exit code:
Just comparing hashes and comparing blob contents. The latter is needed
if certain changes have to be ignored, e.g. with --ignore-space-change
or --ignore-matching-lines. It's enabled by the diff_options flag
diff_from_contents.
The code for handling binary files added by 1aaf69e669 (diff: shortcut
for diff'ing two binary SHA-1 objects, 2014-08-16) always uses a quick
hash-only comparison, even if the slow way is taken. We need it to
report a hash difference as a change for the purpose of setting the
exit code, though, but it never did. Fix that.
d7b97b7185 (diff: let external diffs report that changes are
uninteresting, 2024-06-09) set diff_from_contents if external diff
programs are allowed. This is the default e.g. for git diff, and so
that change exposed the inconsistency much more widely.

The 'scalar reconfigure' command is intended to update registered repos
with the latest settings available. However, up to now we were not
reregistering the repos with background maintenance.
In particular, this meant that the background maintenance schedule would
not be updated if there are improvements between versions.
Be sure to register repos for maintenance during the reconfigure step.

At the moment, some background jobs are getting blocked on credentials
during the 'prefetch' task. This leads to other tasks, such as
incremental repacks, getting blocked. Further, if a user manages to fix
their credentials, then they still need to cancel the background process
before their background maintenance can continue working.
Update the background schedules for our four scheduler integrations to
include these config options via '-c' options:
* 'credential.interactive=false' will stop Git and some credential
helpers from prompting in the UI (assuming the '-c' parameters are
carried through and respected by GCM).
* 'core.askPass=true' will replace the text fallback for a username
and password into the 'true' command, which will return a success in
its exit code, but Git will treat the empty string returned as an
invalid password and move on.
We can do some testing that the credentials are passed, at least in the
systemd case due to writing the service files.

When scripts or background maintenance wish to perform HTTP(S) requests,
there is a risk that our stored credentials might be invalid. At the
moment, this causes the credential helper to ping the user and block the
process. Even if the credential helper does not ping the user, Git falls
back to the 'askpass' method, which includes a direct ping to the user
via the terminal.
Even setting the 'core.askPass' config as something like 'echo' will
causes Git to fallback to a terminal prompt. It uses
git_terminal_prompt(), which finds the terminal from the environment and
ignores whether stdin has been redirected. This can also block the
process awaiting input.
Create a new config option to prevent user interaction, favoring a
failure to a blocked process.
The chosen name, 'credential.interactive', is taken from the config
option used by Git Credential Manager to already avoid user
interactivity, so there is already one credential helper that integrates
with this option. However, older versions of Git Credential Manager also
accepted other string values, including 'auto', 'never', and 'always'.
The modern use is to use a boolean value, but we should still be
careful that some users could have these non-booleans. Further, we
should respect 'never' the same as 'false'. This is respected by the
implementation and test, but not mentioned in the documentation.
The implementation for the Git interactions takes place within
credential_getpass(). The method prototype is modified to return an
'int' instead of 'void'. This allows us to detect that no attempt was
made to fill the given credential, changing the single caller slightly.
Also, a new trace2 region is added around the interactive portion of the
credential request. This provides a way to measure the amount of time
spent in that region for commands that _are_ interactive. It also makes
a conventient way to test that the config option works with
'test_region'.

It has been reported than running
git submodule status --recurse | grep -q ^+
results in an unexpected error message
fatal: failed to recurse into submodule $submodule
When "git submodule--helper" recurses into a submodule it creates a
child process. If that process fails then the error message above is
displayed by the parent. In the case above the child is killed by
SIGPIPE as "grep -q" exits as soon as it sees the first match. Fix this
by propagating SIGPIPE so that it is visible to the process running
git. We could propagate other signals but I'm not sure there is much
value in doing that. In the common case of the user pressing Ctrl-C or
Ctrl-\ then SIGINT or SIGQUIT will be sent to the foreground process
group and so the parent process will receive the same signal as the
child.

With the recent effort to make the test suite free of memory leaks we
now run a lot more of test suites with the leak-sanitizer enabled. While
we were originally only executing around 23000 tests, we're now at 30000
tests. Naturally, this has a significant impact on the runtime of such a
test run.
Naturally, this impact can also be felt for our leak-checking CI jobs.
While macOS used to be the slowest-executing job on GitLab CI with ~15
minutes of runtime, nowadays it is our leak checks which take around 45
to 55 minutes.
Our Linux runners for GitLab CI are untagged, which means that they
default to the "small" machine type with two CPU cores [1]. Upgrade
these to the "medium" runner, which provide four CPU cores and which
should thus provide a noticeable speedup.
In theory, we could upgrade to an ever larger machine than that. The
official mirror [2] has an Ultimate license, so we could get up to 128
cores. But anybody running a fork of the Git project without such a
license wouldn't be able to use those beefier machines and thus their
pipelines would fail.

In a15d4465a9 (cmake: also build unit tests, 2023-09-25), I
accommodated the CMake definition. Seeing that a `UNIT_TEST_OBJS` list
was introduced that was built by transforming the `UNIT_TEST_PROGRAMS`
list and then adding a single, hard-coded file
("t/unit-tests/test-lib.c"), I decided to hard-code that in the CMake
definition, too.
The reason why I hard-coded it instead of imitating the
`parse_makefile_for_sources()` paradigm that was used elsewhere when
using the `Makefile` as source of truth for given lists of files: This
function expects _only_ hard-coded values, and that transformed
`UNIT_TEST_PROGRAMS` list complicated everything.
In 872721538c (cmake: fix build of `t-oidtree`, 2024-07-12), I
accommodated the CMake definition again, after seeing that the
`UNIT_TEST_OBJS` was still defined via that transformed list but now
appending _two_ hard-coded files ("t/unit-tests/lib-oid.c" joined the
fray).
In 428672a3b1 (Makefile: stop listing test library objects twice,
2024-09-16), the `Makefile` was changed so that `UNIT_TEST_OBJS` is
finally only constructed using hard-coded file names just like the other
`*_OBJS` variables. I missed that and therefore did not adjust the CMake
definition. Besides, the code was working, so there was no real need to
adjust it.
With a4f50bb1e9 (t/unit-tests: introduce reftable library, 2024-09-16),
however, the `UNIT_TEST_OBJS` list became a trio, and the CMake
definition has to be adjusted again. Now that we can use the
`parse_makefile_for_sources()` function without many complications,
let's do that.
