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:

and ci/install-dependencies does the appropriate "apt-get update".

d3da223f22 cache-tree: prefetch in partial clone read-tree
"git read-tree" checks the existence of the blobs referenced by the
given tree, but does not bulk prefetch them. Add a bulk prefetch.

The lack of prefetch here was noticed at $DAYJOB during a merge
involving some specific commits, but I couldn't find a minimal merge
that didn't also trigger the prefetch in check_updates() in
unpack-trees.c (and in all these cases, the lack of prefetch in
cache-tree.c didn't matter because all the relevant blobs would have
already been prefetched by then). This is why I used read-tree here to
exercise this code path.

63766510a1 bundle tests: use test_cmp instead of grep
Change the bundle tests to fully compare the expected "git ls-remote"
or "git bundle list-heads" output, instead of merely grepping it.

This avoids subtle regressions in the tests. In
f62e0a39b6 (t5704 (bundle): add tests for bundle --stdin, 2010-04-19)
the "bundle --stdin <rev-list options>" test was added to make sure we
didn't include the tag.

But since the --stdin mode didn't work until 5bb0fd2cab (bundle:
arguments can be read from stdin, 2021-01-11) our grepping of
"master" (later "main") missed the important part of the test.

Namely that we should not include the "refs/tags/tag" tag in that
case. Since the test only grepped for "main" in the output we'd miss a
regression in that code.

So let's use test_cmp instead, and also in the other nearby tests
where it's easy.

This does make things a bit more verbose in the case of the test
that's checking the bundle header, since it's different under SHA1 and
SHA256. I think this makes test easier to follow.

I've got some WIP changes to extend the "git bundle" command to dump
parts of the header out, which are easier to understand if we test the
output explicitly like this.

ddcb189d9d pack-bitmap: clarify comment in filter_bitmap_exclude_type()
The code that eventually became filter_bitmap_exclude_type() was
originally introduced in 4f3bd5606a (pack-bitmap: implement BLOB_NONE

In 856e12c18a (pack-bitmap.c: make object filtering functions generic,
2020-05-04), it became filter_bitmap_exclude_type(). But not all of the
comments were updated to be agnostic to the provided type.

Remove the remaining comments which should have been updated in
856e12c18a to reflect the type-agnostic nature of the function.

878b399734 doc: clarify description of 'submodule.recurse'
The doc for 'submodule.recurse' starts with "Specifies if commands
recurse into submodles by default". This is not exactly true of all
commands that have a '--recurse-submodules' option. For example, 'git
pull --recurse-submodules' does not run 'git pull' in each submodule,
but rather runs 'git submodule update --recursive' so that the submodule
working trees after the pull matches the commits recorded in the
superproject.

Clarify that by just saying that it enables '--recurse-submodules'.

Note that the way this setting interacts with 'fetch.recurseSubmodules'
and 'push.recurseSubmodules', which can have other values than true or
false, is already documented since 4da9e99e6e (doc: be more precise on
(fetch|push).recurseSubmodules, 2020-04-06).

734283855f doc/git-config: simplify "override" advice for FILES section
At the end of the FILES section, we indicate that you can override the
regular lookup rules with --global, etc. But:

  - we're missing the --local option

  - we point to GIT_CONFIG instead of --file, but the latter has much
    better documentation

  - we're vague about how the overrides work; the actual option
    descriptions are much better here

So let's just mention the names and point people back to the OPTIONS
section. We could perhaps even delete this paragraph entirely, but the
presence of the names may give people reading FILES a clue about where
to look for more information.

b3b186262f doc/git-config: clarify GIT_CONFIG environment variable
The scope and utility of the GIT_CONFIG variable was drastically reduced
by dc87183189 (Only use GIT_CONFIG in "git config", not other programs,
2008-06-30). But the documentation in git-config(1) predates that, which
makes it rather misleading.

These days it is really just another way to say "--file". So let's say
that, and explicitly make it clear that it does not impact other Git
commands (like GIT_CONFIG_SYSTEM, etc, would).

I also bumped it to the bottom of the list of variables, and warned
people off of using it. We don't have any plans for deprecation at this
point, but there's little point in encouraging people to use it by
putting it at the top of the list.

ade1552598 t0000: fix test if run with TEST_OUTPUT_DIRECTORY
Testcases in t0000 are quite special given that they many of them run
nested testcases to verify that testing functionality itself works as
expected. These nested testcases are realized by writing a new ad-hoc
test script which again sources test-lib.sh, where the new script is
created in a nested subdirectory located beneath the current trash
directory. We then execute the new test script with the nested
subdirectory as current working directory and explicitly re-export
TEST_OUTPUT_DIRECTORY to point to that directory.

While this works as expected in the general case, it falls apart when
the developer has TEST_OUTPUT_DIRECTORY explicitly defined either via
the environment or via config.mak and runs "make test". In that case,
test-lib.sh will clobber the value that we've just carefully set up to
instead contain what the developer has defined. As a result, the
TEST_OUTPUT_DIRECTORY continues to point at the root output directory,
not at the nested one.

This issue causes breakage in the 'test_atexit is run' test case: the
nested test case writes files into "../../", which is assumed to be the
parent's trash directory. But because TEST_OUTPUT_DIRECTORY already
points to to the root output directory, we instead end up writing those
files outside of the output directory. The parent test case will then
try to check whether those files still exist in its own trash directory,
which thus must fail now.

Fix the issue by adding a new TEST_OUTPUT_DIRECTORY_OVERRIDE variable.
If set, then we'll always override the TEST_OUTPUT_DIRECTORY with its
value after sourcing GIT-BUILD-OPTIONS.

88617d11f9 multi-pack-index: fix potential segfault without sub-command
Since cd57bc41bb (builtin/multi-pack-index.c: display usage on
unrecognized command, 2021-03-30) we have used a "usage" label to avoid
having two separate callers of usage_with_options (one when no arguments
are given, and another for unrecognized sub-commands).

But the first caller has been broken since cd57bc41bb, since it will
happily jump to usage without arguments, and then pass argv[0] to the
"unrecognized subcommand" error.

Many compilers will save us from a segfault here, but the end result is
ugly, since it mentions an unrecognized subcommand when we didn't even
pass one, and (on GCC) includes "(null)" in its output.

Move the "usage" label down past the error about unrecognized
subcommands so that it is only triggered when it should be. While we're
at it, bulk up our test coverage in this area, too.

ac223c4047 t0000: clear GIT_SKIP_TESTS before running sub-tests
In t0000, we run several fake "sub-test" suites to verify the behavior
of the test suite. But because we don't clear the parent environment
completely, the sub-tests can be fooled by variables meant for the
parent. For example:

  GIT_SKIP_TESTS=t1234 ./t0000-basic.sh

fails when a sub-test expects its fake t1234 to actually run. This
particular pattern is unlikely in practice; we're running a single
script, and there is no t1234 in the real test suite anyway (not yet, at
least). A more real-world example is:

  GIT_SKIP_TESTS=t[^0]* make test

to run only the t0* tests.

The fix is conceptually simple: we should clear the GIT_SKIP_TESTS
variable when running the sub-tests, because its contents (if any) will
be meant for the main test suite. This is easy to do centrally in our
sub-test helper.

But there's a catch: some of our tests do set GIT_SKIP_TESTS
intentionally to test the feature. We need to allow them to continue to
set it, but clear it for all the other tests. And the sub-test helper
can't tell if the GIT_SKIP_TESTS it sees is from a test or not. We can
handle this by adding a new option to the helper to let callers specify
the skip list.

I considered adding a more general "--eval" option to let callers set up
the env for the sub-test however they like. That would cover this case
and possible future ones. But the quoting gets awkward for the callers
(since we're now 2 layers deep in evals!), so I went with the simpler
more specific solution.

64f0109f17 test-lib-functions: use test-tool for [de]packetize()
The shell+perl "[de]packetize()" helper functions were added in
4414a15002 (t/lib-git-daemon: add network-protocol helpers,
2018-01-24), and around the same time we added the "pkt-line" helper
in 74e7002961 (test-pkt-line: introduce a packet-line test helper,
2018-03-14).

For some reason it seems we've mostly used the shell+perl version
instead of the helper since then. There were discussions around
88124ab263 (test-lib-functions: make packetize() more efficient,
2020-03-27) and cacae4329f (test-lib-functions: simplify packetize()
stdin code, 2020-03-29) to improve them and make them more efficient.

There was one good reason to do so, we needed an equivalent of
"test-tool pkt-line pack", but that command wasn't capable of handling
input with "\n" (a feature) or "\0" (just because it happens to be
printf-based under the hood).

Let's add a "pkt-line-raw" helper for that, and expose is at a
packetize_raw() to go with the existing packetize() on the shell
level, this gives us the smallest amount of change to the tests
themselves.
