Whenever a branch is pushed to a repository which has GitHub Actions
enabled, a bunch of new workflow runs are started.
We sometimes see contributors push multiple branch updates in rapid
succession, which in conjunction with the impressive time swallowed by
even just a single CI build frequently leads to many queued-up runs.
This is particularly problematic in the case of Pull Requests where a
single contributor can easily (inadvertently) prevent timely builds for
other contributors when using a shared repository.
To help with this situation, let's use the `concurrency` feature of
GitHub workflows, essentially canceling GitHub workflow runs that are
obsoleted by more recent runs:
https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#concurrency
For workflows that *do* want the behavior in the pre-image of this
patch, they can use the ci-config feature to disable the new behavior by
adding an executable script on the ci-config branch called
'skip-concurrent' which terminates with a non-zero exit code.

As well as removing the explicit shell setting d8b21a0fe2 (CI: don't
explicitly pick "bash" shell outside of Windows, fix regression,
2022-12-07) also reverted the name of the print test failures step
introduced by 5aeb145780f (ci(github): bring back the 'print test
failures' step, 2022-06-08). This is unfortunate as 5aeb145780f added a
message to direct contributors to the "print test failures" step when a
test fails and that step is no-longer known by that name on the
non-windows ci jobs.
In principle we could update the message to print the correct name for
the step but then we'd have to deal with having two different names for
the same step on different jobs. It is simpler for the implementation
and contributors to use the same name for this step on all jobs.

It has been a frequent matter of contention that the win+VS jobs not
only take a long time to run, but are also more easily broken than the
other jobs (because they do not use the same `Makefile`-based builds as
all other jobs), and to make matters worse, these breakages are also
much harder to diagnose and fix than other jobs', especially for
contributors who are happy to stay away from Windows.
The purpose of these win+VS jobs is to maintain the CMake-based build
of Git, with the target audience being Visual Studio users on Windows
who are typically quite unfamiliar with `make` and POSIX shell
scripting, but the benefit of whose expertise we want for the Git
project nevertheless.
The CMake support was introduced for that specific purpose, and already
early on concerns were raised that it would put an undue burden on
contributors to ensure that these jobs pass in CI, when they do not have
access to Windows machines (nor want to have that).
This developer's initial hope was that it would be enough to fix win+VS
failures and provide the changes to be squashed into contributors'
patches, and that it would be worth the benefit of attracting
Windows-based developers' contributions.
Neither of these hopes have panned out.
To lower the frustration, and incidentally benefit from using way less
build minutes, let's just not run the win+VS jobs by default, which
appears to be the consensus of the mail thread leading up to
https://lore.kernel.org/git/xmqqk0311blt.fsf@gitster.g/
Since the Git for Windows project still needs to at least try to attract
more of said Windows-based developers, let's keep the jobs, but disable
them everywhere except in Git for Windows' fork. This will help because
Git for Windows' branch thicket is "continuously rebased" via automation
to the `shears/maint`, `shears/main`, `shears/next` and `shears/seen`
branches at https://github.com/git-for-windows/git. That way, the Git
for Windows project will still be notified early on about potential
breakages, but the Git project won't be burdened with fixing them
anymore, which seems to be the best compromise we can get on this issue.

When the "js/ci-github-workflow-markup" topic was originally merged in
[1] it included a change to get rid of the "ci/print-test-failures.sh"
step[2]. This was then brought back in [3] as part of a fix-up patches
on top[4].
The problem was that [3] was not a revert of the relevant parts of
[2], but rather copy/pasted the "ci/print-test-failures.sh" step that
was present for the Windows job to all "ci/print-test-failures.sh"
steps. The Windows steps specified "shell: bash", but the non-Windows
ones did not.
This broke the "ci/print/test-failures.sh" step for the "linux-musl"
job, where we don't have a "bash" shell, just a "/bin/sh" (a
"dash"). This breakage was reported at the time[5], but hadn't been
fixed.
It would be sufficient to change this only for "linux-musl", but let's
change this for both "regular" and "dockerized" to omit the "shell"
line entirely, as we did before [2].
Let's also change undo the "name" change that [3] made while
copy/pasting the "print test failures" step for the Windows job. These
steps are now the same as they were before [2], except that the "if"
includes the "env.FAILED_TEST_ARTIFACTS" test.

GitHub starts to upgrade its runner image "ubuntu-latest" from version
"ubuntu-20.04" to version "ubuntu-22.04". It will fail to find and
install "gcc-8" package on the new runner image.
Change some of the runner images from "ubuntu-latest" to "ubuntu-20.04"
in order to install "gcc-8" as a dependency.
The first revision of this patch tried to replace "$runs_on_pool" in
"ci/*.sh" with a new "$runs_on_os" environment variable based on the
"os" field in the matrix strategy. But these "os" fields in matrix
strategies are obsolete legacies from commit [1] and commit [2], and
are no longer useful. So remove these unused "os" fields.

The old version we currently use runs in node.js v12.x, which is being
deprecated in GitHub Actions. The new version uses node.js v16.x.
Incidentally, this also avoids the warning about the deprecated

`github-script` Action uses the recommended new way to specify outputs.

The current code is clean with these two sanitizers, and we would
like to keep it that way by running the checks for any new code.
The signal of "passed with asan, but not ubsan" (or vice versa) is
not that useful in practice, so it is tempting to run both santizers
in a single task, but it seems to take forever, so tentatively let's
try having two separate ones.

GitHub Actions scheduled a brownout of Ubuntu 18.04, which canceled all
runs of the 'static-analysis' job in our CI runs. Update to 22.04 to

The use of 18.04 was set in d051ed77ee6 (.github/workflows/main.yml: run

Git now shows better information in the GitHub workflow runs when a test
case failed. However, when a test case was implemented incorrectly and
therefore does not even run, nothing is shown.
Let's bring back the step that prints the full logs of the failed tests,
and to improve the user experience, print out an informational message
for readers so that they do not have to know/remember where to see the
full logs.

When investigating a test failure, the time that matters most is the
time it takes from getting aware of the failure to displaying the output
of the failing test case.
You currently have to know a lot of implementation details when
investigating test failures in the CI runs. The first step is easy: the
failed job is marked quite clearly, but when opening it, the failed step
is expanded, which in our case is the one running
`ci/run-build-and-tests.sh`. This step, most notably, only offers a
high-level view of what went wrong: it prints the output of `prove`
which merely tells the reader which test script failed.
The actually interesting part is in the detailed log of said failed
test script. But that log is shown in the CI run's step that runs
`ci/print-test-failures.sh`. And that step is _not_ expanded in the web
UI by default. It is even marked as "successful", which makes it very
easy to miss that there is useful information hidden in there.
Let's help the reader by showing the failed tests' detailed logs in the
step that is expanded automatically, i.e. directly after the test suite
failed.
This also helps the situation where the _build_ failed and the
`print-test-failures` step was executed under the assumption that the
_test suite_ failed, and consequently failed to find any failed tests.
An alternative way to implement this patch would be to source
`ci/print-test-failures.sh` in the `handle_test_failures` function to
show these logs. However, over the course of the next few commits, we
want to introduce some grouping which would be harder to achieve that
way (for example, we do want a leaner, and colored, preamble for each
failed test script, and it would be trickier to accommodate the lack of
nested groupings in GitHub workflows' output).

The "linux-clang" and "linux-gcc" jobs both run "make test" twice, but
with different environment variables. Running these in sequence seems
to have been done to work around some constraint on Travis, see
ae59a4e44f3 (travis: run tests with GIT_TEST_SPLIT_INDEX, 2018-01-07).
By having these run in parallel we'll get jobs that finish much sooner
than they otherwise would have.
We can also simplify the control flow in "ci/run-build-and-tests.sh"
as a result, since we won't run "make test" twice we don't need to run
"make" twice at all, let's default to "make all test" after setting
the variables, and then override it to just "all" for the compile-only
tests.
Add a comment to clarify that new "test" targets should adjust
$MAKE_TARGETS rather than being added after the "case/esac". This
should avoid future confusion where e.g. the compilation-only
"pedantic" target will unexpectedly start running tests. See [1] and
[2].

Change the setup hooks for the CI to use "$runs_on_pool" for the
"$regular" job. Now we won't need as much boilerplate when adding new
jobs to the "regular" matrix, see 956d2e4639b (tests: add a test mode
for SANITIZE=leak, run it in CI, 2021-09-23) for the last such commit.
I.e. now instead of needing to enumerate each jobname when we select
packages we can install things depending on the pool we're running
in.
That we didn't do this dates back to the now gone dependency on Travis
CI, but even if we add a new CI target in the future this'll be easier
to port over, since we can probably treat "ubuntu-latest" as a
stand-in for some recent Linux that can run "apt" commands.

hurt readability in the short view compared to saying "ubuntu" or

As described in https://trojansource.codes/trojan-source.pdf, it is
possible to abuse directional formatting (a feature of Unicode) to
deceive human readers into interpreting code differently from compilers.
For example, an "if ()" expression could be enclosed in a comment, but
rendered as if it was outside of that comment. In effect, this could
fool a reviewer into misinterpreting the code flow as benign when it is
not.
It is highly unlikely that Git's source code wants to contain such
directional formatting in the first place, so let's just disallow it.

On the Windows build agents, a lot of programs are installed, and added
to the PATH automatically.
One such program is Git for Windows, and due to the way it is set up,
unfortunately its copy of `gpg.exe` is also reachable via the PATH.
This usually does not pose any problems. To the contrary, it even allows
us to test the GPG parts of Git's test suite even if `gpg.exe` is not
delivered as part of `git-sdk-64-minimal`, the minimal subset of Git for
Windows' SDK that we use in the CI builds to compile Git.
However, every once in a while we build a new MSYS2 runtime, which means
that there is a mismatch between the copy in `git-sdk-64-minimal` and
the copy in C:\Program Files\Git\usr\bin. When that happens we hit the
dreaded problem where only one `msys-2.0.dll` is expected to be in the
PATH, and things start to fail.
Let's avoid all of this by restricting the PATH to the minimal set. This
is actually done by `git-sdk-64-minimal`'s `/etc/profile`, and we just
have to source this file manually (one would expect that it is sourced
automatically, but the Bash steps in Azure Pipelines/GitHub workflows
are explicitly run using `--noprofile`, hence the need for doing this
explicitly).

While git can be compiled with SANITIZE=leak, we have not run
regression tests under that mode. Memory leaks have only been fixed as
one-offs without structured regression testing.
This change adds CI testing for it. We'll now build and small set of
whitelisted t00*.sh tests under Linux with a new job called
"linux-leaks".
The CI target uses a new GIT_TEST_PASSING_SANITIZE_LEAK=true test
mode. When running in that mode, we'll assert that we were compiled
with SANITIZE=leak. We'll then skip all tests, except those that we've
opted-in by setting "TEST_PASSES_SANITIZE_LEAK=true".
A test setting "TEST_PASSES_SANITIZE_LEAK=true" setting can in turn
make use of the "SANITIZE_LEAK" prerequisite, should they wish to
selectively skip tests even under
"GIT_TEST_PASSING_SANITIZE_LEAK=true". In the preceding commit we
started doing this in "t0004-unwritable.sh" under SANITIZE=leak, now
it'll combine nicely with "GIT_TEST_PASSING_SANITIZE_LEAK=true".
This is how tests that don't set "TEST_PASSES_SANITIZE_LEAK=true" will
be skipped under GIT_TEST_PASSING_SANITIZE_LEAK=true:
$ GIT_TEST_PASSING_SANITIZE_LEAK=true ./t0001-init.sh
1..0 # SKIP skip all tests in t0001 under SANITIZE=leak, TEST_PASSES_SANITIZE_LEAK not set
The intent is to add more TEST_PASSES_SANITIZE_LEAK=true annotations
as follow-up change, but let's start small to begin with.
In ci/run-build-and-tests.sh we make use of the default "*" case to
run "make test" without any GIT_TEST_* modes. SANITIZE=leak is known
to fail in combination with GIT_TEST_SPLIT_INDEX=true in
t0016-oidmap.sh, and we're likely to have other such failures in
various GIT_TEST_* modes. Let's focus on getting the base tests
passing, we can expand coverage to GIT_TEST_* modes later.
It would also be possible to implement a more lightweight version of
this by only relying on setting "LSAN_OPTIONS". See
<YS9OT/pn5rRK9cGB@coredump.intra.peff.net>[1] and
<YS9ZIDpANfsh7N+S@coredump.intra.peff.net>[2] for a discussion of
that. I've opted for this approach of adding a GIT_TEST_* mode instead
because it's consistent with how we handle other special test modes.
Being able to add a "!SANITIZE_LEAK" prerequisite and calling
"test_done" early if it isn't satisfied also means that we can more
incrementally add regression tests without being forced to fix
widespread and hard-to-fix leaks at the same time.
We have tests that do simple checking of some tool we're interested
in, but later on in the script might be stressing trace2, or common
sources of leaks like "git log" in combination with the tool (e.g. the
commit-graph tests). To be clear having a prerequisite could also be
accomplished by using "LSAN_OPTIONS" directly.
On the topic of "LSAN_OPTIONS": It would be nice to have a mode to
aggregate all failures in our various scripts, see [2] for a start at
doing that which sets "log_path" in "LSAN_OPTIONS". I've punted on
that for now, it can be added later.
As of writing this we've got major regressions between master..seen,
i.e. the t000*.sh tests and more fixed since 31f9acf9ce2 (Merge branch
'ah/plugleaks', 2021-08-04) have regressed recently.
See the discussion at <87czsv2idy.fsf@evledraar.gmail.com>[3] about
the lack of this sort of test mode, and 0e5bba53af (add UNLEAK
annotation for reducing leak false positives, 2017-09-08) for the
initial addition of SANITIZE=leak.
See also 09595ab381 (Merge branch 'jk/leak-checkers', 2017-09-19),
7782066f67 (Merge branch 'jk/apache-lsan', 2019-05-19) and the recent
936e58851a (Merge branch 'ah/plugleaks', 2021-05-07) for some of the
past history of "one-off" SANITIZE=leak (and more) fixes.
As noted in [5] we can't support this on OSX yet until Clang 14 is
released, at that point we'll probably want to resurrect that
"osx-leaks" job.

The repository of git-l10n is a fork of "git/git" on GitHub, and uses
GitHub pull request for code review. A helper program "git-po-helper"
can be used to check typos in ".po" files, validate syntax, and check
commit messages. It would be convenient to integrate this helper program
to CI and add comments in pull request.
The new github-action workflow will be enabled for l10n related
operations, such as:
* Operations on a repository named as "git-po", such as a repository
forked from "git-l10n/git-po".
* Push to a branch that contains "l10n" in the name.
* Pull request from a remote branch which has "l10n" in the name, such
as: "l10n/fix-fuzzy-translations".
The new l10n workflow listens to two types of github events:
on: [push, pull_request_target]
The reason we use "pull_request_target" instead of "pull_request" is
that pull requests from forks receive a read-only GITHUB_TOKEN and
workflows cannot write comments back to pull requests for security
reasons. GitHub provides a "pull_request_target" event to resolve
security risks by checking out the base commit from the target
repository, and provide write permissions for the workflow.
By default, administrators can set strict permissions for workflows. The
following code is used to modify the permissions for the GITHUB_TOKEN
and grant write permission in order to create comments in pull-requests.
permissions:
pull-requests: write
This workflow will scan commits one by one. If a commit does not look
like a l10n commit (no file in "po/" has been changed), the scan process
will stop immediately. For a "push" event, no error will be reported
because it is normal to push non-l10n commits merged from upstream. But
for the "pull_request_target" event, errors will be reported. For this
reason, additional option is provided for "git-po-helper".
git-po-helper check-commits \
--github-action-event="${{ github.event_name }}" -- \
<base>..<head>
The output messages of "git-po-helper" contain color codes not only for
console, but also for logfile. This is because "git-po-helper" uses a
package named "logrus" for logging, and I use an additional option
"ForceColor" to initialize "logrus" to print messages in a user-friendly
format in logfile output. These color codes help produce beautiful
output for the log of workflow, but they must be stripped off when
creating comments for pull requests. E.g.:
perl -pe 's/\e\[[0-9;]*m//g' git-po-helper.out
"git-po-helper" may generate two kinds of suggestions, errors and
warnings. All the errors and warnings will be reported in the log of the
l10n workflow. However, warnings in the log of the workflow for a
successfully running "git-po-helper" can easily be ignored by users.
For the "pull_request_target" event, this issue is resolved by creating
an additional comment in the pull request. A l10n contributor should try
to fix all the errors, and should pay attention to the warnings.

During a run of the `check-whitespace` we want to verify that the
commits introduced in the Pull Request have no whitespace issues. We
only want to look at those commits, not the upstream commits (because
the contributor cannot do anything about the latter).
However, by using the `-<count>` form in `git log --check`, we run the
risk of looking at the wrong commits. The reason is that the
`actions/checkout` step does _not_ check out the tip commit of the Pull
Request's branch: Instead, it checks out a merge commit that merges that
branch into the target branch. For that reason, we already adjust the
commit count by incrementing it, but that is not enough: if the upstream
branch has newer commits, they are traversed _first_. And obviously we
will then miss some of the commits that we _actually_ wanted to look at.
Therefore, let's be careful to stop assuming a linear, up to date commit
topology in the contributed commits, and instead specify the correct
commit range.
Unfortunately, this means that we no longer can rely on a shallow clone:
There is no way of knowing just how many commits the upstream branch
advanced after the commit from which the PR branch branched off. So
let's just go with a full clone instead, and be safe rather than sorry
(if we have "too shallow" a situation, a commit range `@{u}..` may very
well include a shallow commit itself, and the output of `git show
--check <shallow>` is _not_ pretty).
