Add a wrapper script to allow `prove` to run both shell tests and unit
tests from a single invocation. This avoids issues around running prove
twice in CI, as discussed in [1].
Additionally, this moves the unit tests into the main dev workflow, so
that errors can be spotted more quickly. Accordingly, we remove the
separate unit tests step for Linux CI. (We leave the Windows CI
unit-test step as-is, because the sharding scheme there involves
selecting specific test files rather than running `make test`.)

Newer versions of Ubuntu have dropped Python 2 starting with Ubuntu
23.04. By default though, our CI setups will try to use that Python
version on all Ubuntu-based jobs except for the "linux-gcc" one.
We didn't notice this issue due to two reasons:
- The "ubuntu:latest" tag always points to the latest LTS release.
Until a few weeks ago this was Ubuntu 22.04, which still had Python
2.
- Our Docker-based CI jobs had their own script to install
dependencies until 9cdeb34b96 (ci: merge scripts which install
dependencies, 2024-04-12), where we didn't even try to install
Python at all for many of them.
Since the CI refactorings have originally been implemented, Ubuntu
24.04 was released, and it being an LTS versions means that the "latest"
tag now points to that Python-2-less version. Consequently, those jobs
that use "ubuntu:latest" broke.
Address this by using Python 2 on Ubuntu 20.04, only, whereas we use
Python 3 on all other Ubuntu jobs. Eventually, we should think about
dropping support for Python 2 completely.

Since 5e47215080 (fuzz: add basic fuzz testing target., 2018-10-12), we
have compiled object files for the fuzz tests as part of the default
'make all' target. This helps prevent bit-rot in lesser-used parts of
the codebase, by making sure that incompatible changes are caught at
build time.
However, since we never linked the fuzzer executables, this did not
protect us from link-time errors. As of 8b9a42bf48 (fuzz: fix fuzz test
build rules, 2024-01-19), it's now possible to link the fuzzer
executables without using a fuzzing engine and a variety of
compiler-specific (and compiler-version-specific) flags, at least on
Linux. So let's add a platform-specific option in config.mak.uname to
link the executables as part of the default `make all` target.
Since linking the fuzzer executables without a fuzzing engine does not
require a C++ compiler, we can change the FUZZ_PROGRAMS build rule to
use $(CC) by default. This avoids compiler mis-match issues when
overriding $(CC) but not $(CXX). When we *do* want to actually link with
a fuzzing engine, we can set $(FUZZ_CXX). The build instructions in the
CI fuzz-smoke-test job and in the Makefile comment have been updated
accordingly.
While we're at it, we can consolidate some of the fuzzer build
instructions into one location in the Makefile.

Part of "install-dependencies.sh" is to install some binaries required
for tests into a custom directory that gets added to the PATH. This
directory is located at "$HOME/path" and thus depends on the current
user that the script executes as.
This creates problems for GitLab CI, which installs dependencies as the
root user, but runs tests as a separate, unprivileged user. As their
respective home directories are different, we will end up using two
different custom path directories. Consequently, the unprivileged user
will not be able to find the binaries that were set up as root user.
Fix this issue by allowing CI to override the custom path, which allows
GitLab to set up a constant value that isn't derived from "$HOME".

Our "install-dependencies.sh" script is executed by non-dockerized jobs

We're about to merge "install-docker-dependencies.sh" into that script

thus unnecessary there, even though it would be harmless. On some images

To prevent bitrot, we would like to regularly exercise the fuzz tests in
order to make sure they still link & run properly. We already compile
the fuzz test objects as part of the default `make` target, but we do
not link the executables due to the fuzz tests needing specific
compilers and compiler features. This has lead to frequent build
breakages for the fuzz tests.
To remedy this, we can add a CI step to actually link the fuzz
executables, and run them (with finite input rather than the default
infinite random input mode) to verify that they execute properly.
Since the main use of the fuzz tests is via OSS-Fuzz [1], and OSS-Fuzz
only runs tests on Linux [2], we only set up a CI test for the fuzzers
on Linux.

Add a job to GitLab CI which runs tests on macOS, which matches the
equivalent "osx-clang" job that we have for GitHub Workflows. One
significant difference though is that this new job runs on Apple M1
machines and thus uses the "arm64" architecture. As GCC does not yet
support this comparatively new architecture we cannot easily include an
equivalent for the "osx-gcc" job that exists in GitHub Workflows.
Note that one test marked as `test_must_fail` is surprisingly passing:
t7815-grep-binary.sh (Wstat: 0 Tests: 22 Failed: 0)
TODO passed: 12
This seems to boil down to an unexpected difference in how regcomp(3P)

When setting up Perforce on macOS we put both `p4` and `p4d` into
"$HOME/bin". On GitHub CI this directory is indeed contained in the PATH
environment variable and thus there is no need for additional setup than
to put the binaries there. But GitLab CI does not do this, and thus our
Perforce-based tests would be skipped there even though we download the
binaries.
Refactor the setup code to become more robust by downloading binaries
into a separate directory which we then manually append to our PATH.
This matches what we do on Linux-based jobs.
Note that it may seem like we already did append "$HOME/bin" to PATH
because we're actually removing the lines that adapt PATH. But we only
ever adapted the PATH variable in "ci/install-dependencies.sh", and
didn't adapt it when running "ci/run-build-and-test.sh". Consequently,

Process to add some form of low-level unit tests has started.
* js/doc-unit-tests:

This is a late amendment of 4a6e4b9602 (CI: remove Travis CI support,
2021-11-23), whereby the `.prove` file (being written by the `prove`
command that is used to run the test suite) is no longer retained
between CI builds: This feature was only ever used in the Travis CI
builds, we tried for a while to do the same in Azure Pipelines CI runs
(but I gave up on it after a while), and we never used that feature in
GitHub Actions (nor does the new GitLab CI code use it).
Retaining the Prove cache has been fragile from the start, even though
the idea seemed good at the time, the idea being that the `.prove` file
caches information about previous `prove` runs (`save`) and uses them
(`slow`) to run the tests in the order from longer-running to shorter
ones, making optimal use of the parallelism implied by `--jobs=<N>`.
However, using a Prove cache can cause some surprising behavior: When
the `prove` caches information about a test script it has run,
subsequent `prove` runs (with `--state=slow`) will run the same test
script again even if said script is not specified on the `prove`
command-line!
So far, this bug did not matter. Right until d8f416bbb8 (ci: run unit
tests in CI, 2023-11-09) did it not matter.
But starting with that commit, we invoke `prove` _twice_ in CI, once to
run the regular test suite of regression test scripts, and once to run
the unit tests. Due to the bug, the second invocation re-runs all of the
tests that were already run as part of the first invocation. This not
only wastes build minutes, it also frequently causes the `osx-*` jobs to
fail because they already take a long time and now are likely to run
into a timeout.
The worst part about it is that there is actually no benefit to keep
running with `--state=slow,save`, ever since we decided no longer to
try to reuse the Prove cache between CI runs.
So let's just drop that Prove option and live happily ever after.

We already support Azure Pipelines and GitHub Workflows in the Git
project, but until now we do not have support for GitLab CI. While it is
arguably not in the interest of the Git project to maintain a ton of
different CI platforms, GitLab has recently ramped up its efforts and
tries to contribute to the Git project more regularly.
Part of a problem we hit at GitLab rather frequently is that our own,
custom CI setup we have is so different to the setup that the Git
project has. More esoteric jobs like "linux-TEST-vars" that also set a
couple of environment variables do not exist in GitLab's custom CI
setup, and maintaining them to keep up with what Git does feels like
wasted time. The result is that we regularly send patch series upstream
that fail to compile or pass tests in GitHub Workflows. We would thus
like to integrate the GitLab CI configuration into the Git project to
help us send better patch series upstream and thus reduce overhead for
the maintainer. Results of these pipeline runs will be made available
(at least) in GitLab's mirror of the Git project at [1].
This commit introduces the integration into our regular CI scripts so
that most of the setup continues to be shared across all of the CI
solutions. Note that as the builds on GitLab CI run as unprivileged
user, we need to pull in both sudo and shadow packages to our Alpine
based job to set this up.

which causes us to skip a subset of tests.
Install these test dependencies to increase our test coverage on this
platform. There are still some missing test dependecies, but these do

- p4 and p4d, both parts of the Perforce version control system.
- cvsps, which generates patch sets for CVS.
- Subversion and the SVN::Core Perl library, the latter of which is
not available in the Alpine repositories. While the tool itself is
available, all Subversion-related tests are skipped without the
SVN::Core Perl library anyway.
The Apache2-based tests require a bit more care though. For one, the
module path is different on Alpine Linux, which requires us to add it to
the list of known module paths to detect it. But second, the WebDAV
module on Alpine Linux is broken because it does not bundle the default
database backend [1]. We thus need to skip the WebDAV-based tests on

Unify the setup of those environment variables so that only the uncommon

It doesn't hurt on platforms where we don't persist the state, so

Make the grouping setup more generic by always calling `begin_group ()`
and `end_group ()` regardless of whether we have stubbed those functions
or not. This ensures we can more readily add support for additional CI
platforms.
Furthermore, the `group ()` function is made generic so that it is the
same for both GitHub Actions and for other platforms. There is a
semantic conflict here though: GitHub Actions used to call `set +x` in
`group ()` whereas the non-GitHub case unconditionally uses `set -x`.
The latter would get overriden if we kept the `set +x` in the generic
version of `group ()`. To resolve this conflict, we simply drop the `set
+x` in the generic variant of this function. As `begin_group ()` calls
`set -x` anyway this is not much of a change though, as the only
commands that aren't printed anymore now are the ones between the
beginning of `group ()` and the end of `begin_group ()`.
Last, this commit changes `end_group ()` to also accept a parameter that
indicates _which_ group should end. This will be required by a later

adds to the end-to-end latency of the whole workflow. But we don't want
to do that immediately, as people need time to migrate until the
CI_BRANCHES change has made it into the workflow file of every branch.
So let's issue a warning, which will appear in the "annotations" section
below the workflow result in GitHub's web interface. And let's remove
the sample allow-refs script, as we don't want to encourage anybody to
use it.

When we added config to skip CI for certain branches in e76eec3554 (ci:
allow per-branch config for GitHub Actions, 2020-05-07), there wasn't
any way to avoid spinning up a VM just to check the config. From the
developer's perspective this isn't too bad, as the "skipped" branches
complete successfully after running the config job (the workflow result
is "success" instead of "skipped", but that is a minor lie).
But we are still wasting time and GitHub's CPU to spin up a VM just to
check the result of a short shell script. At the time there wasn't any
way to avoid this. But they've since introduced repo-level variables
that should let us do the same thing:
https://github.blog/2023-01-10-introducing-required-workflows-and-configuration-variables-to-github-actions/#configuration-variables
This is more efficient, and as a bonus is probably less confusing to
configure (the existing system requires sticking your config on a magic
ref).
See the included docs for how to configure it.
The code itself is pretty simple: it checks the variable and skips the
config job if appropriate (and everything else depends on the config job
already). There are two slight inaccuracies here:
- we don't insist on branches, so this likewise applies to tag names
or other refs. I think in practice this is OK, and keeping the code
(and docs) short is more important than trying to be more exact. We
are targeting developers of git.git and their limited workflows.
- the match is done as a substring (so if you want to run CI for
"foobar", then branch "foo" will accidentally match). Again, this
should be OK in practice, as anybody who uses this is likely to only
specify a handful of well-known names. If we want to be more exact,
we can have the code check for adjoining spaces. Or even move to a
more general CI_CONFIG variable formatted as JSON. I went with this
scheme for the sake of simplicity.

Every once in a while, the `git-p4` tests flake for reasons outside of
our control. It typically fails with "Connection refused" e.g. here:
https://github.com/git/git/actions/runs/5969707156/job/16196057724
[...]
+ git p4 clone --dest=/home/runner/work/git/git/t/trash directory.t9807-git-p4-submit/git //depot
Initialized empty Git repository in /home/runner/work/git/git/t/trash directory.t9807-git-p4-submit/git/.git/
Perforce client error:
Connect to server failed; check $P4PORT.
TCP connect to localhost:9807 failed.
connect: 127.0.0.1:9807: Connection refused
failure accessing depot: could not run p4
Importing from //depot into /home/runner/work/git/git/t/trash directory.t9807-git-p4-submit/git
[...]
This happens in other jobs, too, but in the `linux-asan-ubsan` job it
hurts the most because that job often takes over a full hour to run,
therefore re-running a failed `linux-asan-ubsan` job is _very_ costly.
The purpose of the `linux-asan-ubsan` job is to exercise the C code of
Git, anyway, and any part of Git's source code that the `git-p4` tests
run and that would benefit from the attention of ASAN/UBSAN are run
better in other tests anyway, as debugging C code run via Python scripts
can get a bit hairy.
In fact, it is not even just `git-p4` that is the problem (even if it
flakes often enough to be problematic in the CI builds), but really the
part about Python scripts. So let's just skip any Python parts of the
tests from being run in that job.
For good measure, also skip the Subversion tests because debugging C
code run via Perl scripts is as much fun as debugging C code run via
Python scripts. And it will reduce the time this very expensive job
takes, which is a big benefit.

The object traversal using reachability bitmap done by
"pack-object" has been tweaked to take advantage of the fact that
using "boundary" commits as representative of all the uninteresting
ones can save quite a lot of object enumeration.
* tb/pack-bitmap-traversal-with-boundary:
pack-bitmap.c: use commit boundary during bitmap traversal
pack-bitmap.c: extract `fill_in_bitmap()`
object: add object_array initializer helper function
Clang's sanitizer implementation seems to work better than GCC's.
* jk/ci-use-clang-for-sanitizer-jobs:
ci: drop linux-clang job
ci: run ASan/UBSan in a single job
ci: use clang for ASan/UBSan checks
