Ævar Arnfjörð Bjarmason 25715419bf CI: don't run "make test" twice in one job
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
ae59a4e44f (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].

Ævar Arnfjörð Bjarmason 707d2f2fe8 CI: use "$runs_on_pool", not "$jobname" to select packages & config
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 956d2e4639 (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.

Ævar Arnfjörð Bjarmason df7375d772 CI: use shorter names that fit in UX tooltips
Change the names used for the GitHub CI workflows to be short enough
to (mostly) fit in the pop-up tool-tips that GitHub shows in the
commit view. I.e. when mouse-clicking on the passing or failing
check-mark next to the commit subject.

These names are seemingly truncated to 17-20 characters followed by
three dots ("..."). Since a "CI/PR / " prefix is added to them the job
names looked like this before (windows-test and vs-test jobs omitted):

    CI/PR / ci-config (p...

    CI/PR / static-anal...
    CI/PR / sparse (pu...
    CI/PR / documenta...

By omitting the "/PR" from the top-level name, and pushing the
$jobname to the front we'll now instead get:

    CI / config (push)
    CI / win build (push...
    CI / win+VS build (...

    CI / documentation

We then have no truncation in the expanded view. See [1] for how it
looked before, [2] for a currently visible CI run using this commit,
and [3] for the GitHub workflow syntax involved being changed here.

Let's also use the existing "pool" field as before. It's occasionally
useful to know we're running on say ubuntu v.s. fedora. The "-latest"
suffix is useful to some[4], and since it's now at the end it doesn't
hurt readability in the short view compared to saying "ubuntu" or
"macos".

Johannes Schindelin 0e7696c64d ci: disallow directional formatting
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.

Johannes Schindelin 7491ef6198 ci(windows): ensure that we do not pick up random executables
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).

Ævar Arnfjörð Bjarmason 956d2e4639 tests: add a test mode for SANITIZE=leak, run it in CI
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 31f9acf9ce (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.

Jiang Xin a788d31931 ci: new github-action for git-l10n code review
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.

Johannes Schindelin a066a90db6 ci(check-whitespace): restrict to the intended commits
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).

Johannes Schindelin cc00362125 ci(check-whitespace): stop requiring a read/write token
As part of some recent security tightening, GitHub introduced the
ability to configure GitHub workflows to be run with a read-only token.
This is much more secure, in particular when working in a public
repository: While the regular read/write token might be restricted to
writing to the current branch, it is not necessarily restricted to
access only the current Pull Request.

However, the `check-whitespace` workflow threw a wrench into this plan:
it _requires_ write access (because it wants to add a PR comment in case
of a whitespace issue).

Let's just skip that PR comment. The user can always click through to
the actual error, even if it is slightly less convenient.

Johannes Schindelin e61059660c ci: run `make sparse` as part of the GitHub workflow
Occasionally we receive reviews after patches were integrated, where
`sparse` (https://sparse.docs.kernel.org/en/latest/ has more information
on that project) identified problems such as file-local variables or
functions being declared as global.

By running `sparse` as part of our Continuous Integration, we can catch
such things much earlier. Even better: developers who activated GitHub
Actions on their forks can catch such issues before even sending their
patches to the Git mailing list.

This addresses https://github.com/gitgitgadget/git/issues/345

Note: Not even Ubuntu 20.04 ships with a new enough version of `sparse`
to accommodate Git's needs. The symptom looks like this:

    add-interactive.c:537:51: error: Using plain integer as NULL pointer

To counter that, we download and install the custom-built `sparse`
package from the Azure Pipeline that we specifically created to address
this issue.

We already build Git for Windows with `NO_GETTEXT` when compiling with
GCC. Let's do the same with Visual C, too.

Note that we do not technically _need_ to pass `NO_GETTEXT` explicitly

`NO_GETTEXT = YesPlease`). But it is definitely nicer to be explicit

Johannes Schindelin d681d0dc3a ci (windows): transfer also the Git-tracked files to the test jobs
Git's test suite is excruciatingly slow on Windows, mainly due to the
fact that it executes a lot of shell script code, and that's simply not
native to Windows.

To help with that, we established the pattern where the artifacts are
first built in one job, and then multiple test jobs run in parallel
using the artifacts built in the first job.

We take pains in transferring only the build outputs, and letting
`actions/checkout` fill in the rest of the files.

One major downside of that strategy is that the test jobs might fail to
check out the intended revision (e.g. because the branch has been
updated while the build was running, as is frequently the case with the
`seen` branch).

Let's transfer also the files tracked by Git, and skip the checkout step
in the test jobs.

Johannes Schindelin 0eb6c189a3 ci: use the new GitHub Action to download git-sdk-64-minimal
In our continuous builds, Windows is the odd cookie that requires a
complete development environment to be downloaded because there is no
suitable one installed by default on Windows.

Side note: technically, there _is_ a development environment present in
GitHub Actions' build agents: MSYS2. But it differs from Git for
Windows' SDK in subtle points, unfortunately enough so to prevent Git's
test suite from running without failures.

Traditionally, we support downloading this environment (which we
nicknamed `git-sdk-64-minimal`) via a PowerShell scriptlet that accesses
the build artifacts of a dedicated Azure Pipeline (which packages a tiny
subset of the full Git for Windows SDK, containing just enough to build
Git and run its test suite).

This PowerShell script is unfortunately not very robust and sometimes
fails due to network issues.

Of course, we could add code to detect that situation, wait a little,
try again, if it fails again wait a little longer, lather, rinse and
repeat.

Instead of doing all of this in Git's own `.github/workflows/`, though,
let's offload this logic to the new GitHub Action at
https://github.com/marketplace/actions/setup-git-for-windows-sdk

This Action not only downloads and extracts git-sdk-64-minimal _outside_
the worktree (making it no longer necessary to meddle with
`.gitignore` or `.git/info/exclude`), it also adds the `bash.exe` to the
`PATH` and sets the environment variable `MSYSTEM` (an implementation
detail that Git's workflow should never have needed to know about).

This allows us to convert all those funny PowerShell tasks that wanted
to call git-sdk-64-minimal's `bash.exe`: they all are now regular `bash`
scriptlets.

This finally lets us get rid of the funny quoting and escaping where we
had to pay attention not only to quote and escape the Bash scriptlets
properly, but also to add a second level of escaping (with backslashes
for double quotes and backticks for dollar signs) to stop PowerShell
from doing unintended things.

Further, this Action uses a fast caching strategy native to GitHub
Actions that should accelerate the download across CI runs:
git-sdk-64-minimal is usually updated once per 24h, and needs to be
cached only once within that period. Caching it (unfortunately only on
a per-branch basis) speeds up the download step, and makes it much more
robust at the same time by virtue of accessing a cache location that is
closer in the network topology.

With this we can drop the home-rolled caching where we try to accelerate
the test phase by uploading git-sdk-64-minimal as a workflow artifact
after using it to build Git, and then download it as workflow artifact
in the test phase.

Even better: the `vs-test` job no longer needs to depend on the
`windows-build` job. The only reason it depended on it was to ensure
that the `git-sdk-64-minimal` workflow artifact was available.

Dennis Ameling 958a5f5dfe cmake(install): include vcpkg dlls
Our CMake configuration generates not only build definitions, but also
install definitions: After building Git using `msbuild git.sln`, the
built artifacts can be installed via `msbuild INSTALL.vcxproj`.

To specify _where_ the files should be installed, the
`-DCMAKE_INSTALL_PREFIX=<path>` option can be used when running CMake.

However, this process would really only install the files that were just
built. On Windows, we need more than that: We also need the `.dll` files
of the dependencies (such as libcurl). The `vcpkg` ecosystem, which we
use to obtain those dependencies, can be asked to install said `.dll`
files really easily, so let's do that.

This requires more than just the built `vcpkg` artifacts in the CI build
definition; We now clone the `vcpkg` repository so that the relevant
CMake scripts are available, in particular the ones related to defining
the toolchain.

Philippe Blain 2b0e14f640 ci: do not cancel all jobs of a matrix if one fails
The CI/PR GitHub Actions workflow uses the 'matrix' strategy for the
"windows-test", "vs-test", "regular" and "dockerized" jobs. The default
behaviour of GitHub Actions is to cancel all in-progress jobs in a
matrix if one of the job of the matrix fails [1].

This is not ideal as a failure early in a job, like during installation of
the build/test dependencies on a specific platform, leads to the
cancellation of all other jobs in the matrix.

Set the 'fail-fast' variable to 'false' for all four matrix jobs in the
workflow.

Ævar Arnfjörð Bjarmason 6c280b4142 ci: remove GETTEXT_POISON jobs
A subsequent commit will remove GETTEXT_POISON entirely, let's start
by removing the CI jobs that enable the option.

We cannot just remove the job because the CI is implicitly depending
on the "poison" job being a sort of "default" job in the sense that
it's the job that was otherwise run with the default compiler, no
other GIT_TEST_* options etc. So let's keep it under the name
"linux-gcc-default".

This means we can remove the initial "make test" from the "linux-gcc"
job (it does another one after setting a bunch of GIT_TEST_*
variables).

I'm not doing that because it would conflict with the in-flight
334afbc76f (tests: mark tests relying on the current default for
`init.defaultBranch`, 2020-11-18) (currently on the "seen" branch, so
the SHA-1 will almost definitely change). It's going to use that "make
test" again for different reasons, so let's preserve it for now.

Let's be even more defensive by catching all kinds of exceptions,
logging them as warnings, and continue the run without skipping it
(after all, if the check fails, we _want_ to continue with the run).

This commit is best viewed with the diff option `-w` because it
