We used to call that function already before printing the final verdict.
However, now that we added grouping to the GitHub workflow output, we
will want to include even that part in the collapsible group for that
test case.

This makes the output easier to digest.
Note: since workflow output currently cannot contain any nested groups
(see https://github.com/actions/runner/issues/802 for details), we need
to remove the explicit grouping that would span the entirety of each

In most instances, looking at the log of failed test cases is enough to
identify the problem.
In some (rare?) instances, a previous test case that was marked as
successful actually has information pertaining to a later test case that
fails.
To allow the page to load relatively quickly, let's only show the logs
of the failed test cases to be shown. The full logs are available for
download as artifacts, should a deeper investigation become necessary.

A couple of commands exist to spruce up the output in GitHub workflows:
https://docs.github.com/en/actions/learn-github-actions/workflow-commands-for-github-actions
In addition to the `::group::<label>`/`::endgroup::` commands (which we
already use to structure the output of the build step better), we also
use `::error::`/`::notice::` to draw the attention to test failures and
to test cases that were expected to fail but didn't.

The current output of Git's GitHub workflow can be quite confusing,
especially for contributors new to the project.
To make it more helpful, let's introduce some collapsible grouping.
Initially, readers will see the high-level view of what actually
happened (did the build fail, or the test suite?). To drill down, the
respective group can be expanded.
Note: sadly, workflow output currently cannot contain any nested groups
(see https://github.com/actions/runner/issues/802 for details),
therefore we take pains to ensure to end any previous group before
starting a new one.

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).

In the web UI of GitHub workflows, failed runs are presented with the
job step that failed auto-expanded. In the current setup, this is not
helpful at all because that shows only the output of `prove`, which says
which test failed, but not in what way.
What would help understand the reader what went wrong is the verbose
test output of the failed test.
The logs of the failed runs do contain that verbose test output, but it
is shown in the _next_ step (which is marked as succeeding, and is
therefore _not_ auto-expanded). Anyone not intimately familiar with this
would completely miss the verbose test output, being left mostly
puzzled with the test failures.
We are about to show the failed test cases' output in the _same_ step,
so that the user has a much easier time to figure out what was going
wrong.
But first, we must partially revert the change that tried to improve the
CI runs by combining the `Makefile` targets to build into a single
`make` invocation. That might have sounded like a good idea at the time,
but it does make it rather impossible for the CI script to determine
whether the _build_ failed, or the _tests_. If the tests were run at
all, that is.
So let's go back to calling `make` for the build, and call `make test`
separately so that we can easily detect that _that_ invocation failed,
and react appropriately.

In the test case's output, we do want newline characters, but in the XML
attributes we do not want them.
However, the `xml_attr_encode` function always adds a Line Feed at the
end (which are then encoded as `

This seems not to faze Azure Pipelines' XML parser, but it still is
incorrect, so let's fix it.

The code writing JUnit XML is interspersed directly with all the code in
`t/test-lib.sh`, and it is therefore not only ill-separated, but
introducing yet another output format would make the situation even
worse.
Let's introduce an abstraction layer by hiding the JUnit XML code behind
four new functions that are supposed to be called before and after each
test and test case.
This is not just an academic exercise, refactoring for refactoring's
sake. We _actually_ want to introduce such a new output format, to
make it substantially easier to diagnose test failures in our GitHub
workflow, therefore we do need this refactoring.

.gitignore-d, 2017-12-31), a function was introduced with a code style
that is different from the surrounding code: it added the opening curly
brace on its own line, when all the existing functions in the same file
cuddle that brace on the same line as the function name.

The previous patch demonstrates a scenario where the list of packs
written by `pack-objects` (and stored in the `names` string_list) is
out-of-order, and can thus cause us to delete packs we shouldn't.
This patch resolves that bug by ensuring that `names` is sorted in all
cases, not just when
delete_redundant && pack_everything & ALL_INTO_ONE
is true.
Because we did sort `names` in that case (which, prior to `--geometric`
repacks, was the only time we would actually delete packs, this is only
a bug for `--geometric` repacks.
It would be sufficient to only sort `names` when `delete_redundant` is
set to a non-zero value. But sorting a small list of strings is cheap,
and it is defensive against future calls to `string_list_has_string()`
on this list.

When doing a `--geometric=<d>` repack, `git repack` determines a
splitting point among packs ordered by their object count such that:
- each pack above the split has at least `<d>` times as many objects
as the next-largest pack by object count, and
- the first pack above the split has at least `<d>` times as many
object as the sum of all packs below the split line combined
`git repack` then creates a pack containing all of the objects contained
in packs below the split line by running `git pack-objects
--stdin-packs` underneath. Once packs are moved into place, then any
packs below the split line are removed, since their objects were just
combined into a new pack.
But `git repack` tries to be careful to avoid removing a pack that it
just wrote, by checking:
struct packed_git *p = geometry->pack[i];
if (string_list_has_string(&names, hash_to_hex(p->hash)))
continue;
in the `delete_redundant` and `geometric` conditional towards the end of
`cmd_repack`.
But it's possible to trick `git repack` into not recognizing a pack that
it just wrote when `names` is out-of-order (which violates
`string_list_has_string()`'s assumption that the list is sorted and thus
binary search-able).
When this happens in just the right circumstances, it is possible to
remove a pack that we just wrote, leading to object corruption.
Luckily, this is quite difficult to provoke in practice (for a couple of
reasons):
- we ordinarily write just one pack, so `names` usually contains just
one entry, and is thus sorted
- when we do write more than one pack (e.g., due to `--max-pack-size`)
we have to: (a) write a pack identical to one that already
exists, (b) have that pack be below the split line, and (c) have
the set of packs written by `pack-objects` occur in an order which
tricks `string_list_has_string()`.
Demonstrate the above scenario in a failing test, which causes `git
repack --geometric` to write a pack which occurs below the split line,
_and_ fail to recognize that it wrote that pack.
The following patch will fix this bug.

Update 'repack' to ignore packs named on the command line with the
'--keep-pack' option. Specifically, modify 'init_pack_geometry()' to treat
command line-kept packs the same way it treats packs with an on-disk '.keep'
file (that is, skip the pack and do not include it in the 'geometry'
structure).
Without this handling, a '--keep-pack' pack would be included in the
'geometry' structure. If the pack is *before* the geometry split line (with
at least one other pack and/or loose objects present), 'repack' assumes the
pack's contents are "rolled up" into another pack via 'pack-objects'.
However, because the internally-invoked 'pack-objects' properly excludes
'--keep-pack' objects, any new pack it creates will not contain the kept
objects. Finally, 'repack' deletes the '--keep-pack' as "redundant" (since
it assumes 'pack-objects' created a new pack with its contents), resulting
in possible object loss and repository corruption.
Add a test ensuring that '--keep-pack' packs are now appropriately handled.

In c7c4bdeccf (run-command API: remove "env" member, always use
"env_array", 2021-11-25), there was a push to replace
cld.env = env->v;
with
strvec_pushv(&cld.env_array, env->v);
The conversion in c7c4bdeccf was mostly plug-and-play, with the snag
that some instances of strvec_pushv() became guarded with a NULL check
to ensure that the second argument was non-NULL.
This conversion was slightly over-eager to add a conditional in
builtin/receive-pack.c::unpack(), since we know at the point that we
add the result of `tmp_objdir_env()` into the child process's
environment, that `tmp_objdir` is non-NULL.
This follows from the conditional just before our strvec_pushv() call
(which returns from the function if `tmp_objdir` was NULL), as well as
the call to tmp_objdir_add_as_alternate() just below, which relies on
its argument (`tmp_objdir`) being non-NULL.
In the meantime, this extra conditional isn't hurting anything. But it
is redundant and thus unnecessarily confusing. So let's remove it.

When 7dce19d3 (fetch/pull: Add the --recurse-submodules option,
2010-11-12) introduced the "--recurse-submodule" option, the
approach taken was to perform fetches in submodules only once, after
all the main fetching (it may usually be a fetch from a single
remote, but it could be fetching from a group of remotes using
fetch_multiple()) succeeded. Later we added "--all" to fetch from
all defined remotes, which complicated things even more.
If your project has a submodule, and you try to run "git fetch
--recurse-submodule --all", you'd see a fetch for the top-level,
which invokes another fetch for the submodule, followed by another
fetch for the same submodule. All but the last fetch for the
submodule come from a "git fetch --recurse-submodules" subprocess
that is spawned via the fetch_multiple() interface for the remotes,
and the last fetch comes from the code at the end.
Because recursive fetching from submodules is done in each fetch for
the top-level in fetch_multiple(), the last fetch in the submodule
is redundant. It only matters when fetch_one() interacts with a
single remote at the top-level.
While we are at it, there is one optimization that exists in dealing
with a group of remote, but is missing when "--all" is used. In the
former, when the group turns out to be a group of one, instead of
spawning "git fetch" as a subprocess via the fetch_multiple()
interface, we use the normal fetch_one() code path. Do the same
when handing "--all", if it turns out that we have only one remote
defined.

This switch statement was recently added to make it clear that
unpack_loose_header() returns an enum value, not an int. This adds
complications for future developers if that enum gains new values, since
that developer would need to add a case statement to this switch for
little real value.
Instead, we can revert back to an 'if' statement, but make the enum
explicit by using "!= ULHR_OK" instead of assuming it has the numerical
value zero.
