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].

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.

4a6e4b9602 CI: remove Travis CI support
Remove support for running the CI in travis. The last builds in it are
from 5 months ago[1] (as of 2021-11-19), and our documentation has
referred to GitHub CI instead since f003a91f5c (SubmittingPatches:
replace discussion of Travis with GitHub Actions, 2021-07-22).

We'll now run the "t9810 t9816" and tests on OSX. We didn't before, as
we'd carried the Travis exclusion of them forward from
522354d70f (Add Travis CI support, 2015-11-27). Let's hope whatever
issue there was with them was either Travis specific, or fixed since
then (I'm not sure).

The "apt-add-repository" invocation (which we were doing in GitHub CI)
isn't needed, it was another Travis-only case that was carried forward
into more general code. See 0f0c51181d (travis-ci: install packages
in 'ci/install-dependencies.sh', 2018-11-01).

Remove the "linux-gcc-4.8" job added in fb9d7431cf (travis-ci: build
with GCC 4.8 as well, 2019-07-18), it only ran in Travis CI.

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.

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.

482c962de4 t: use user-specified utf-8 locale for testing svn
In some test-cases, UTF-8 locale is required. To find such locale,
we're using the first available UTF-8 locale that returned by
"locale -a".

However, the locale(1) utility is unavailable on some systems,
e.g. Linux with musl libc.

However, without "locale -a", we can't guess provided UTF-8 locale.

Add a Makefile knob GIT_TEST_UTF8_LOCALE and activate it for
linux-musl in our CI system.

Rename t/lib-git-svn.sh:prepare_a_utf8_locale to prepare_utf8_locale,
since we no longer prepare the variable named "a_utf8_locale",
but set up a fallback value for GIT_TEST_UTF8_LOCALE instead.
The fallback will be LC_ALL, LANG environment variable,
or the first UTF-8 locale from output of "locale -a", in that order.

87094fc2da ci: run test round with parallel-checkout enabled
We already have tests for the basic parallel-checkout operations. But
this code can also run be executed by other commands, such as
git-read-tree and git-sparse-checkout, which are currently not tested
with multiple workers. To promote a wider test coverage without
duplicating tests:

1. Add the GIT_TEST_CHECKOUT_WORKERS environment variable, to optionally
   force parallel-checkout execution during the whole test suite.

2. Set this variable (with a value of 2) in the second test round of our
   linux-gcc CI job. This round runs `make test` again with some
   optional GIT_TEST_* variables enabled, so there is no additional
   overhead in exercising the parallel-checkout code here.

Note that tests checking out less than two parallel-eligible entries
will fall back to the sequential mode. Nevertheless, it's still a good
exercise for the parallel-checkout framework as the fallback codepath
also writes the queued entries using the parallel-checkout functions
(only without spawning any worker).

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.

334afbc76f tests: mark tests relying on the current default for init.defaultBranch
In addition to the manual adjustment to let the `linux-gcc` CI job run
the test suite with `master` and then with `main`, this patch makes sure
that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts
that currently rely on the initial branch name being `master by default.

To determine which test scripts to mark up, the first step was to
force-set the default branch name to `master` in

- all test scripts that contain the keyword `master`,

- t4211, which expects `t/t4211/history.export` with a hard-coded ref to
  initialize the default branch,

- t5560 because it sources `t/t556x_common` which uses `master`,

- t8002 and t8012 because both source `t/annotate-tests.sh` which also
  uses `master`)

This trick was performed by this command:

	$ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\
	GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
	export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
	' $(git grep -l master t/t[0-9]*.sh) \
	t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh

After that, careful, manual inspection revealed that some of the test
scripts containing the needle `master` do not actually rely on a
specific default branch name: either they mention `master` only in a
comment, or they initialize that branch specificially, or they do not
actually refer to the current default branch. Therefore, the
aforementioned modification was undone in those test scripts thusly:

We excluded one set of test scripts in these commands, though: the range
of `git p4` tests. The reason? `git p4` stores the (foreign) remote
branch in the branch called `p4/master`, which is obviously not the
default branch. Manual analysis revealed that only five of these tests
actually require a specific default branch name to pass; They were
modified thusly:

	$ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\
	GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
	export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
	' t/t980[0167]*.sh t/t9811*.sh

4463ce75b7 ci: do not skip tagged revisions in GitHub workflows
When `master` is tagged, and then both `master` and the tag are pushed,
Travis CI will happily build both. That is a waste of energy, which is
why we skip the build for `master` in that case.

Our GitHub workflow is also triggered by tags. However, the run would
fail because the `windows-test` jobs are _not_ skipped on tags, but the
`windows-build` job _is skipped (and therefore fails to upload the
build artifacts needed by the test jobs).

In addition, we just added logic to our GitHub workflow that will skip
runs altogether if there is already a successful run for the same commit
or at least for the same tree.

Let's just change the GitHub workflow to no longer specifically skip
tagged revisions.

ef60e9f74b ci: stop linking built-ins to the dashed versions
Since e4597aae65 (run test suite without dashed git-commands in PATH,
2009-12-02), we stopped running our tests with `git-foo` binaries found
at the top-level directory of a freshly built source tree; instead we
have placed only `git` and selected `git-foo` commands that must be on
`$PATH` in `bin-wrappers/` and prepended that `bin-wrappers/` to the
`PATH` used in the test suite. We did that to catch the tests and
scripted Git commands that still try to use the dashed form.

Since CI jobs will not install the built Git to anywhere, and the
hardlinks we make at the top-level of the source tree for `git-add` and
friends are not even used during tests, they are pure waste of resources
these days.

Thanks to the newly invented `SKIP_DASHED_BUILT_INS` knob, we can now
skip creating these links in the source tree. So let's do that.

Note that this change introduces a subtle change of behavior: when Git's
`cmd_main()` calls `setup_path()`, it inserts the value of
`GIT_EXEC_PATH` (defaulting to `<prefix>/libexec/git-core`) at the
beginning of the environment variable `PATH`. This is necessary to find
e.g. scripted commands that are installed in that location. For the
purposes of Git's test suite, the `bin-wrappers/` scripts override
`GIT_EXEC_PATH` to point to the top-level directory of the source code.

In other words, if a scripted command had used a dashed invocation of a
built-in Git command, it would not have been caught previously, which is
fixed by this change.

8a06d56ccb ci: run tests with SHA-256
Now that we have Git supporting SHA-256, we'd like to make sure that we
don't regress that state.  Unfortunately, it's easy to do so, so to
help, let's add code to run one of our CI jobs with SHA-256 as the
default hash.  This will help us detect any problems that may occur.

We pick the linux-clang job because it's relatively fast and the
linux-gcc job already runs the testsuite twice.  We want our tests to
run as fast as possible, so we wouldn't want to add a third run to the
linux-gcc job.  To make sure we properly exercise the code, let's run
the tests in the default mode (SHA-1) first and then run a second time
with SHA-256.  We explicitly specify SHA-1 for the first run so that if
we change the default in the future, we make sure to test both cases.

60e47f6773 ci: use absolute PYTHON_PATH in the Linux jobs
In our test suite, when 'git p4' invokes a Git command as a
subprocesses, then it should run the 'git' binary we are testing.
Unfortunately, this is not the case in the 'linux-clang' and
'linux-gcc' jobs on Travis CI, where 'git p4' runs the system
'/usr/bin/git' instead.

Travis CI's default Linux image includes 'pyenv', and all Python
invocations that involve PATH lookup go through 'pyenv', e.g. our
'PYTHON_PATH=$(which python3)' sets '/opt/pyenv/shims/python3' as
PYTHON_PATH, which in turn will invoke '/usr/bin/python3'.  Alas, the
'pyenv' version included in this image is buggy, and prepends the
directory containing the Python binary to PATH even if that is a
system directory already in PATH near the end.  Consequently, 'git p4'
in those jobs ends up with its PATH starting with '/usr/bin', and then
runs '/usr/bin/git'.

So use the absolute paths '/usr/bin/python{2,3}' explicitly when
setting PYTHON_PATH in those Linux jobs to avoid the PATH lookup and
thus the bogus 'pyenv' from interfering with our 'git p4' tests.
Don't bother with special-casing Travis CI: while this issue doesn't
affect the corresponding Linux jobs on GitHub Actions, both CI systems
use Ubuntu LTS-based images, so we can safely rely on these Python
paths.

From e76eec3554 (ci: allow per-branch config for GitHub Actions,

they want to build with GitHub Actions
by checking for a file named "ci/config/allow-ref".

In order to assist those contributors,
we provided a sample in "ci/config/allow-refs.sample",
and instructed them to drop the ".sample",
then commit that file to their repository.

We've misspelt the filename in that change.
Let's fix the spelling.

While we're at it, also instruct our contributors introduce that new
file to Git before commit, in case of they've never told Git before.

e76eec3554 ci: allow per-branch config for GitHub Actions
Depending on the workflows of individual developers, it can either be
convenient or annoying that our GitHub Actions CI jobs are run on every
branch. As an example of annoying: if you carry many half-finished
work-in-progress branches and rebase them frequently against master,
you'd get tons of failure reports that aren't interesting (not to
mention the wasted CPU).

This commit adds a new job which checks a special branch within the
repository for CI config, and then runs a shell script it finds there to
decide whether to skip the rest of the tests. The default will continue
to run tests for all refs if that branch or script is missing.

There have been a few alternatives discussed:

One option is to carry information in the commit itself about whether it
should be tested, either in the tree itself (changing the workflow YAML
file) or in the commit message (a "[skip ci]" flag or similar). But
these are frustrating and error-prone to use:

  - you have to manually apply them to each branch that you want to mark

  - it's easy for them to leak into other workflows, like emailing patches

We could likewise try to get some information from the branch name. But
that leads to debates about whether the default should be "off" or "on",
and overriding still ends up somewhat awkward. If we default to "on",
you have to remember to name your branches appropriately to skip CI. And
if "off", you end up having to contort your branch names or duplicate
your pushes with an extra refspec.

By comparison, this commit's solution lets you specify your config once
and forget about it, and all of the data is off in its own ref, where it
can be changed by individual forks without touching the main tree.

There were a few design decisions that came out of on-list discussion.
I'll summarize here:

 - we could use GitHub's API to retrieve the config ref, rather than a
   real checkout (and then just operate on it via some javascript). We
   still have to spin up a VM and contact GitHub over the network from
   it either way, so it ends up not being much faster. I opted to go
   with shell to keep things similar to our other tools (and really
   could implement allow-refs in any language you want). This also makes
   it easy to test your script locally, and to modify it within the
   context of a normal git.git tree.

 - we could keep the well-known refname out of refs/heads/ to avoid
   cluttering the branch namespace. But that makes it awkward to
   manipulate. By contrast, you can just "git checkout ci-config" to
   make changes.

 - we could assume the ci-config ref has nothing in it except config
   (i.e., a branch unrelated to the rest of git.git). But dealing with
   orphan branches is awkward. Instead, we'll do our best to efficiently
   check out only the ci/config directory using a shallow partial clone,
   which allows your ci-config branch to be just a normal branch, with
   your config changes on top.

 - we could provide a simpler interface, like a static list of ref
   patterns. But we can't get out of spinning up a whole VM anyway, so
   we might as well use that feature to make the config as flexible as
   possible. If we add more config, we should be able to reuse our
   partial-clone to set more outputs.

f72f328bc5 ci: let GitHub Actions upload failed tests' directories
Arguably, CI builds' most important task is to not only identify
regressions, but to make it as easy as possible to investigate what went
wrong.

In that light, we will want to provide users with a way to inspect the
tests' output as well as the corresponding directories.

This commit adds build steps that are only executed when tests failed,
uploading the relevant information as build artifacts. These artifacts
can then be downloaded by interested parties to diagnose the failures
more efficiently.
