Starting with 7a094d68a2 (ci: run expensive tests on push builds to
integration branches, 2026-05-08) we run expensive tests in our CI for
certain events. So far, this has only been wired up for GitHub Workflows
though, which creates a test gap for GitLab CI.
Plug this gap by also making this work for the latter.
Note that these tests cannot be run on the Windows runners, as they only
have 7.5GB of RAM. This is insufficient for some of the EXPENSIVE tests,
so we explicitly disable "GIT_TEST_LONG" on these jobs.

Earlier, we enabled EXPENSIVE tests for pushes to integration
branches. As we didn't have any CI jobs that run these tests, this
was a step in the right direction.
It however is an ineffective and inefficient use of the maintainer
time, which does not scale, to allow contributors to send changes
that are less tested at the list, only to force the maintainer
notice breakages caused by their changes but only after these
changes are mixed with changes from other contributors. The
problematic topic needs to be isolated by bisecting, and it
historically has been done by the maintainer alone.
It is far better to let the problem identified early, preferably
before the problematic code leaves the hands of the original
developer. In order for it to happen, the test coverage of the
contributor tests must be at least as wide as the coverage of the
integration tests.
Enable expensive tests for CI jobs triggered by pull requests. This
will make each contributor take care of their own, which scales much
better.
Keep the expensive tests also enabled for the pushes of integration
branches, as that is the only place we can notice problems stemming
from mismerges and inter-topic interactions, even if the topics from
the contributors in isolation all passes these tests.

Derrick Stolee suggested [1] that expensive tests should be run at a
regular cadence rather than on every PR iteration. Gate GIT_TEST_LONG
on push builds to the integration branches (next, master, main, maint)
so that the EXPENSIVE prereq is satisfied there but not during PR
validation, where the extra minutes of wall-clock time do not justify
themselves.

Our breaking changes document says that we'll enable Rust by default in
Git 2.54. Adjust the Makefile to switch the option from WITH_RUST to
NO_RUST to enable it by default and update the help text accordingly.
Similarly, for Meson, enable the option by default and do not
automatically disable it if Cargo is missing, since the goal is to help
users find where they are likely to have problems in the future.
Update our CI tests to swap out the single Linux job with Rust to a
single job without, both for Makefile and Meson. Similarly, update the
Windows Makefile job to not use Rust, while the Meson job (which does
not build with ci/lib.sh) will default to having it enabled.
Move the check for Cargo in the Meson build because it is no longer
needed in the main script.

We have started to see the following assert happen in our GitLab CI
pipelines for jobs that use Windows with Meson:
assertion "bc_ctl.arg_max >= LINE_MAX" failed: file "xargs.c", line 512, function: main
The assert in question verifies that we have enough room available to
pass at least `LINE_MAX` many bytes via the command line. The xargs(1)
binary in those jobs comes from Git for Windows, which in turn sources
the binaries from MSYS2, and has the following limits in place:
$ & "C:/Program Files/Git/usr/bin/bash.exe" -l -c 'xargs --show-limits </dev/null'
Your environment variables take up 17373 bytes
POSIX upper limit on argument length (this system): 12579
POSIX smallest allowable upper limit on argument length (all systems): 4096
Maximum length of command we could actually use: 18446744073709546822
Size of command buffer we are actually using: 12579
Maximum parallelism (--max-procs must be no greater): 2147483647
What's interesting to see is the limit of 16 exabits for the maximum
command line length. This value might seem a bit high, and it is indeed
the result of an underflow: our environment is larger than the POSIX
upper limit on argument length, and the value is computed by subtracting
the former from the latter. So what we get is the result of `2^64 -
(17373 - 12579)`.
This makes it clear that the problem here is the size of our environment
variables. A listing sorted by length yields the following result:
$ Get-ChildItem "Env:" |
Sort-Object { $_.Value.Length } -Descending |
Select-Object Name, @{Name="Length"; Expression={$_.Value.Length}}
Name Length
---- ------
GITLAB_FEATURES 6386
Path 706
PSModulePath 229
The GITLAB_FEATURES environment variable makes up for roughly a third of
the complete environment. This variable is a comma-separated list of
features available for the GitLab instance, and seemingly it has been
growing over time as GitLab added more and more features.
Fix the issue by unsetting the environment variable in "ci/lib.sh". This
ensures that the environment variables are now smaller than the upper
limit on argument length again, and that in turn fixes the assert in
xargs(1).

I noticed recently that the leak-checking jobs still take a lot of time,
and upon analysis, the git-svn tests contribute significantly to this.
Analyzing a recent CI run, I saw that the Git test suite contains
1,017 tests, running for approximately 5¼ hours total. Of these, 65
git-svn-related tests (~6% of test count) took 42.24 minutes combined,
accounting for ~13.% of the total runtime. This implies that the git-svn
tests are roughly twice as expernsive compared to the other tests.
However, testing git-svn in the leak-checking jobs provides minimal
value: git-svn is implemented as a Perl script, and leak checking only
handles C code. While git-svn does call into Git's built-in commands
that are implemented in C, these are standard Git operations that are
already thoroughly exercised elsewhere in the test suite. Therefore,
running the git-svn tests in the leak-checking jobs only adds to the
overall run time with little value in return.
Given that the leak-checking jobs are particularly time-intensive and
these 42+ minutes of SVN tests per job provide no additional leak
detection value, skip them in the *-leaks jobs to reduce CI runtime.

The musl-based Meson job is supposed to explicitly specify the UTF-8
locale used for testing, which has been introduced with 84bb5eeace7 (ci:
switch linux-musl to use Meson, 2025-01-28). That commit had two issues
though:
- We continue to refer to "linux-musl", even though the job has been
renamed in the same commit to "linux-musl-meson".
- We use the wrong option name to specify the locale. This was not
noticed though due to the first issue.
Fix both of these issues by fixing both the job and option naems.

Switch over the "linux-musl" job to use Meson instead of Makefiles. This
is done due to multiple reasons:
- It simplifies our CI infrastructure a bit as we don't have to
manually specify a couple of build options anymore.
- It verifies that Meson detects and sets those build options
automatically.
- It makes it easier for us to wire up a new CI job using zlib-ng as
backend.
One platform compatibility that Meson cannot easily detect automatically
is the `GIT_TEST_UTF8_LOCALE` variable used in tests. Wire up a build
option for it, which we set via a new "MESONFLAGS" environment variable.
Note that we also drop the CC variable, which is set to "gcc". We
already default to GCC when CC is unset in "ci/lib.sh", so this is not
needed.

The "linux-gcc-default" job is mostly doing the same as the "linux-gcc"
job, except for a couple of minor differences:
- We use an explicit GCC version instead of the default version
provided by the distribution. We have other jobs that test with
"gcc-8", making this distinction pointless.
- We don't set up the Python version explicitly, and instead use the
default Python version. Python 2 has been end-of-life for quite a
while now though, making this distinction less interesting.
- We set up the default branch name to be "main" in "linux-gcc". We
have other testcases that don't and also some that explicitly use
"master".
- We use "ubuntu:20.04" in one job and "ubuntu:latest" in another. We
already have a couple other jobs testing these respectively.
So overall, the job does not add much to our test coverage.
Drop the "linux-gcc-default" job and adapt "linux-gcc" to start using
the default GCC compiler, effectively merging those two jobs into one.

We explicitly list the distro of Linux-based jobs, but it is equivalent
to the name of the image in almost all cases, except that colons are
replaced with dashes. Drop the redundant information and massage it in
our CI scripts, which is equivalent to how we do it in GitLab CI.
There are a couple of exceptions:
- The "linux32" job, whose distro name is different than the image
name. This is handled by adapting all sites to use the new name.
- The "alpine" and "fedora" jobs, neither of which specify a tag for
their image. This is handled by adding the "latest" tag.

The extra "barrier" approach was too much code whose sole purpose
was to work around a race that is not even ours (i.e. in LSan's
teardown code).
In preparation for queuing a solution taking a much-less-invasive
approach, let's revert them.
|
|
One thread primitive we don't yet support is a barrier: it waits for all
threads to reach a synchronization point before letting any of them
continue. This would be useful for avoiding the LSan race we see in
index-pack (and other places) by having all threads complete their
initialization before any of them start to do real work.
POSIX introduced a pthread_barrier_t in 2004, which does what we want.
But if we want to rely on it:
1. Our Windows pthread emulation would need a new set of wrapper
functions. There's a Synchronization Barrier primitive there, which
was introduced in Windows 8 (which is old enough for us to depend
on).
2. macOS (and possibly other systems) has pthreads but not
pthread_barrier_t. So there we'd have to implement our own barrier
based on the mutex and cond primitives.
Those are do-able, but since we only care about avoiding races in our
LSan builds, there's an easier way: make it a noop on systems without a
native pthread barrier.
This patch introduces a "maybe_thread_barrier" API. The clunky name
(rather than just using pthread_barrier directly) should hopefully clue
people in that on some systems it will do nothing. It's wired to a
Makefile knob which has to be triggered manually, and we enable it for
the linux-leaks CI jobs (since we know we'll have it there).
There are some other possible options:
- we could turn it on all the time for Linux systems based on uname.
But we really only care about it for LSan builds, and there is no
need to add extra code to regular builds.
- we could turn it on only for LSan builds. But that would break
builds on non-Linux platforms (like macOS) that otherwise should
support sanitizers.
- we could trigger only on the combination of Linux and LSan together.
This isn't too hard to do, but the uname check isn't completely
accurate. It is really about what your libc supports, and non-glibc
systems might not have it (though at least musl seems to).
So we'd risk breaking builds on those systems, which would need to
add a new knob. Though the upside would be that running local "make
SANITIZE=leak test" would be protected automatically.
And of course none of this protects LSan runs from races on systems
without pthread barriers. It's probably OK in practice to protect only
our CI jobs, though. The race is rare-ish and most leak-checking happens
through CI.

Whenever we source "ci/lib.sh" we wrap the directives in a separate
group so that they can easily be collapsed in the web UI. And as we
source the script multiple times during a single CI run we thus end up
with the same section name reused multiple times, as well.
This is broken on GitLab CI though, where reusing the same group name is
not supported. The consequence is that only the last of these sections
can be collapsed.
Fix this issue by including the name of the sourcing script in the
group's name.

Over the last two releases we have plugged a couple hundred of memory
leaks exposed by the Git test suite. With the preceding commits we have
finally fixed the last leak exposed by our test suite, which means that
we are now basically leak free wherever we have branch coverage.
From hereon, the Git test suite should ideally stay free of memory
leaks. Most importantly, any test suite that is being added should
automatically be subject to the leak checker, and if that test does not
pass it is a strong signal that the added code introduced new memory
leaks and should not be accepted without further changes.
Drop the infrastructure around TEST_PASSES_SANITIZE_LEAK to reflect this
new requirement. Like this, all test suites will be subject to the leak
checker by default.
This is being intentionally strict, but we still have an escape hatch:
the SANITIZE_LEAK prerequisite. There is one known case in t5601 where
the leak sanitizer itself is buggy, so adding this prereq in such cases
is acceptable. Another acceptable situation is when a newly added test
uncovers preexisting memory leaks: when fixing that memory leak would be
sufficiently complicated it is fine to annotate and document the leak
accordingly. But in any case, the burden is now on the patch author to
explain why exactly they have to add the SANITIZE_LEAK prerequisite.
The TEST_PASSES_SANITIZE_LEAK annotations will be dropped in the next
patch.

We try to abstract away any differences between different CI platforms
in "ci/lib.sh", such that knowledge specific to e.g. GitHub Actions or
GitLab CI is neatly encapsulated in a single place. Next to some generic
variables, we also set up some variables that are specific to the actual
platform that the CI operates on, e.g. Linux or macOS.
We do not yet support Windows runners on GitLab CI. Unfortunately, those
systems do not use the same "CI_JOB_IMAGE" environment variable as both
Linux and macOS do. Instead, we can use the "OS" variable, which should
have a value of "Windows_NT" on Windows platforms.

In the preceding commits we had to convert the linux32 job to be based
on Ubuntu 20.04 instead of Ubuntu 16.04 due to a limitation in GitHub
Workflows. This was the only job left that still tested against this old
but supported Ubuntu version, and we have no other jobs that test with a
comparatively old Linux distribution.
Add a new job to GitLab CI that tests with Ubuntu 16.04 to cover the
resulting test gap. GitLab doesn't modify Docker images in the same way
GitHub does and thus doesn't fall prey to the same issue. There are two
compatibility issues uncovered by this:
- Ubuntu 16.04 does not support HTTP/2 in Apache. We thus cannot set
`GIT_TEST_HTTPD=true`, which would otherwise cause us to fail when
Apache fails to start.
- Ubuntu 16.04 cannot use recent JGit versions as they depend on a
more recent Java runtime than we have available. We thus disable
installing any kind of optional dependencies that do not come from
the package manager.
These two restrictions are fine though, as we only really care about
whether Git compiles and runs on such old distributions in the first
place.

As we currently describe in t/README, it can happen that:
Some tests run "git" (or "test-tool" etc.) without properly checking
the exit code, or git will invoke itself and fail to ferry the
abort() exit code to the original caller.
Therefore, GIT_TEST_SANITIZE_LEAK_LOG=true is needed to be set to
capture all memory leaks triggered by our tests.
It seems unnecessary to force users to remember this option, as
forgetting it could lead to missed memory leaks.
We could solve the problem by making it "true" by default, but that
might suggest we think "false" makes sense, which isn't the case.
Therefore, the best approach is to remove the option entirely while
maintaining the capability to detect memory leaks in blind spots of our
tests.

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.

Sections of CI output defined by `begin_group()` and `end_group()` are
expanded in GitLab pipelines by default. This can make CI job output
rather noisy and harder to navigate. Update the behavior for GitLab
pipelines to now collapse sections by default.

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".

We're downloading various executables required by our tests. Each of
these executables goes into its own directory, which is then appended to
the PATH variable. Consequently, whenever we add a new dependency and
thus a new directory, we would have to adapt to this change in several
places.
Refactor this to instead put all binaries into a single directory.

The "runs_on_pool" environment variable is used by our CI scripts to
distinguish the different kinds of operating systems. It is quite
specific to GitHub Actions though and not really a descriptive name.
Rename the variable to "distro" to clarify its intent.

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)
works when matching NUL bytes. Cross-checking with the respective GitHub
job shows that this is not an issue unique to the GitLab CI job as it
passes in the same way there.

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,
the required binaries wouldn't be found during the test run unless the
CI platform already had the "$HOME/bin" in PATH right from the start.
