342e54a3a1 ci(vs-build): download the vcpkg artifacts using a dedicated Action
We now have a GitHub Action to download and cache Azure Pipelines
artifacts (such as the `vcpkg` artifacts), hiding gnarly internals, and
also providing some robustness against network glitches. Let's use it.

6b7889ffec ci(): add HOST_CPU to CMake command
As mentioned in the Makefile and CMakeLists.txt: "When cross-compiling, define HOST_CPU as the canonical name of the CPU on which the built Git will run (for instance "x86_64")"

This commit sets the HOST_CPU variable since Git for Windows arm64 is cross-compiled from an amd64 host.

b509912750 git-artifacts: Use the shiny new setup-git-for-windows-sdk Action
This simplifies the workflow dramatically.

Note that we have to reinstate that `/usr/bin/git` hack (a shell script
that simply redirects to `/mingw64/bin/git.exe`) in the `pkg` job
manually, since we no longer cache the `build-installers` artifact
_after_ installing that hack in `bundle-artifacts`.

2f99cc9281 cmake(): allow setting HOST_CPU for cross-compilation
Git's regular Makefile mentions that HOST_CPU should be defined when cross-compiling Git: 37796bca76/Makefile (L438-L439)

This is then used to set the GIT_HOST_CPU variable when compiling Git: 37796bca76/Makefile (L1337-L1341)

Then, when the user runs `git version --build-options`, it returns that value: 37796bca76/help.c (L658)

This commit adds the same functionality to the CMake configuration. Users can now set -DHOST_CPU= to set the target architecture.

13a8c2a351 git-artifacts: fix BUILD_ONLY handling for ARM64
The workflow allows users to restrict what parts are being built. For
example, `installer-i686` will build only the 32-bit installer, not the
64-bit one nor any MinGit flavor.

However, this logic was not extended when introducing support for ARM64:
Instead, we _also_ built the ARM64 installer when the user asked for
`installer-i686`.

Let's allow restricting to `installer-i686` _without_ building the ARM64
version, and allow restricting to `installer-arm64` _just_ for the ARM64
version.

cf78862a4b git-artifacts: use the cached build-installers instead of makepkg-git
When building the Pacman packages, we technically do not need the full
`build-installers` artifact (which is substantially larger than the
`makepkg-git` artifact). However, the former is already cached and
includes the latter's files. And it is _so_ much faster to download the
cached (larger) artifact than to download the smaller `makepkg-git`
artifact from Azure Pipelines.

67adf4b38b git-artifacts: allow restricting which artifacts are built
Users can now specify which artifacts they want to build, via the
`build_only` input, which is a space-separated list of artifacts. For
example, `installer portable` will build `installer-x86_64`,
`installer-i686`, `portable-x86_64` and `portable-i686`, and an empty or
unset value will build all artifacts.

Please note that the `mingw-w64-git` packages are built always, as it
would be tricky to figure out when they need to be built (for example,
`build_only=portable-x86_64` technically does not need `pkg-i686` to be
built, while `build_only=portable` does).

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).

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.

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.

its use in 32-bit linux (as used by the Linux32 container)

move all dockerized jobs to use v1 that was built in C# and therefore
doesn't have this problem, which will otherwise manifest with confusing

cebead1ebf ci: run a pedantic build as part of the GitHub workflow
similar to the recently added sparse task, it is nice to know as early
as possible.

add a dockerized build using fedora (that usually has the latest gcc)
to be ahead of the curve and avoid older ISO C issues at the same time.

27f45ccf33 ci/install-dependencies: handle "sparse" job package installs
This just matches the style/location of the package installation for
other jobs. There should be no functional change.

I did flip the order of the options and command-name ("-y update"
instead of "update -y") for consistency with other lines in the same
file.

Note also that we have to reorder the dependency install with the
"checkout" action, so that we actually have the "ci" scripts available.

8231c841ff ci: run "apt-get update" before "apt-get install"
The "sparse" workflow runs "apt-get install" to pick up a few necessary
packages. But it needs to run "apt-get update" first, or it risks trying
to download an old package version that no longer exists. And in fact
this happens now, with output like:

  2021-07-26T17:40:51.2554304Z E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

Our other ci jobs don't suffer from this; they rely on scripts in ci/,
and ci/install-dependencies does the appropriate "apt-get update".

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).

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.

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.

0dc787a9f2 ci: accelerate the checkout
By upgrading from v1 to v2 of `actions/checkout`, we avoid fetching all
the tags and the complete history: v2 only fetches one revision by
default. This should make things a lot faster.

Note that `actions/checkout@v2` seems to be incompatible with running in
containers: https://github.com/actions/checkout/issues/151. Therefore,
we stick with v1 there.

9ab0b66129 ci (vs-build): build with NO_GETTEXT
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
in that `make artifacts-tar` invocation because we do this while `MSVC`
is set (which will set `uname_S := Windows`, which in turn will set
`NO_GETTEXT = YesPlease`). But it is definitely nicer to be explicit
here.

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.
