As a follow-up to the preceding commit's shortening of CI job names,
rename the only job that starts with an upper-case letter to be
consistent with the rest. It was added in 88dedd5e72c (Travis: also
test on 32-bit Linux, 2017-03-05).

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...

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 / linux-clang (ub...

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".

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 f003a91f5c5 (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
522354d70f4 (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 0f0c51181df (travis-ci: install packages
in 'ci/install-dependencies.sh', 2018-11-01).
Remove the "linux-gcc-4.8" job added in fb9d7431cf4 (travis-ci: build
with GCC 4.8 as well, 2019-07-18), it only ran in Travis CI.

Some tests in t7006 check for a SIGPIPE result by recording $? and
comparing it with test_match_signal. Before the previous commit, the
command was on the left-hand side of a pipe, and so we had to do some
subshell trickery to extract it.
But now that this is no longer the case, we can do things much more
simply: just run the command directly, using braces to avoid wrecking
the &&-chain, and then record $?. We could almost use test_expect_code
here, but it doesn't know about test_match_signal.
Likewise, for tests which expect success (i.e., not SIGPIPE), we can
just put them in the &&-chain as usual. That even lets us get rid of the
!MINGW check, since the expectation is the same on both sides.

Comit c24b7f6736 (pager: test for exit code with and without SIGPIPE,
2021-02-02) introduced some tests that don't reliably generate SIGPIPE
where we expect it (i.e., when our pager doesn't read all of the output
from git-log).
There are two problems that somewhat cancel each other out.
First is that the output of git-log isn't very large (only around 800
bytes). So even if the pager doesn't read all of our output, it's racy
whether or not we'll actually get a SIGPIPE (we won't if we write all of
the output into the pipe buffer before the pager exits).
But we wrap git-log with test_terminal, which is supposed to propagate
the exit status of git-log. However, it doesn't always do so;
test_terminal will copy to stdout any lines that it got from our fake
pager, and it pipes to an empty command. So most of the time we are
seeing a SIGPIPE from test_terminal itself (though this is likewise
racy).
Let's try to make this more robust in two ways:
1. We'll put a commit with a huge message at the tip of history. Since
this is over a megabyte, it should fill the OS pipe buffer
completely, causing git-log to keep trying to write even after the
pager has exited.
2. We'll redirect the output of test_terminal to /dev/null. That means
it can never get SIGPIPE itself, and will always be giving us the
exit code from git-log.
These two changes reveal that one of the tests was looking for the wrong
behavior. If we try to start a pager that does not exist (according to
execve()), then the error propagates from start_command() back to the
pager code as an error, and we avoid redirecting git-log's stdout to the
broken pager entirely. Instead, it goes straight to the original stdout
(test_terminal's pty in this case), and we do not see a SIGPIPE at all.
So the test "git attempts to page to nonexisting pager command, gets
SIGPIPE" is checking the wrong outcome; it should be looking for a
successful exit (and was only confused by test_terminal's SIGPIPE).
There's a related test, "git discards nonexisting pager without
SIGPIPE", which sets the pager to a shell command which will read all
input and _then_ run a non-existing command. But that doesn't trigger
the same execve() behavior. We really do run the shell there and
redirect git-log's stdout to it. And the fact that the shell then exits
127 is not interesting. It is not different at that point than the
earlier test to check for "exit 1". So we can drop that test entirely.

Since 507d7804c0 (pager: don't use unsafe functions in signal handlers,
2015-09-04), we have a separate code path in wait_or_whine() for the
case that we're in a signal handler. But that code path misses some of
the cases handled by the main logic.
This was improved in be8fc53e36 (pager: properly log pager exit code
when signalled, 2021-02-02), but that covered only case: actually
returning the correct error code. But there are some other cases:
- if waitpid() returns failure, we wouldn't notice and would look at
uninitialized garbage in the status variable; it's not clear if it's
possible to trigger this or not
- if the process exited by signal, then we would still report "-1"
rather than the correct signal code
This latter case even had a test added in be8fc53e36, but it doesn't
work reliably. It sets the pager command to:
>pager-used; test-tool sigchain
The latter command will die by signal, but because there are multiple
commands, there will be a shell in between. And it's the shell whose
waitpid() call will see the signal death, and it will then exit with
code 143, which is what Git will see.
To make matters even more confusing, some shells (such as bash) will
realize that there's nothing for the shell to do after test-tool
finishes, and will turn it into an exec. So the test was only checking
what it thought when /bin/sh points to a shell like bash (we're relying
on the shell used internally by Git to spawn sub-commands here, so even
running the test under bash would not be enough).
This patch adjusts the tests to explicitly call "exec" in the pager
command, which produces a consistent outcome regardless of shell. Note
that without the code change in this patch it _should_ fail reliably,
but doesn't. That test, like its siblings, tries to trigger SIGPIPE in
the git-log process writing to the pager, but only do so racily. That
will be fixed in a follow-on patch.
For the code change here, we have two options:
- we can teach the in_signal code to handle WIFSIGNALED()
- we can stop returning early when in_signal is set, and instead
annotate individual calls that we need to skip in this case
The former is a simpler patch, but means we're essentially duplicating
all of the logic. So instead I went with the latter. The result is a
bigger patch, and we do run the risk of new code being added but
forgetting to handle in_signal. But in the long run it seems more
maintainable.
I've skipped any non-trivial calls for the in_signal case, like calling
error(). We'll also skip the call to clear_child_for_cleanup(), as we
were before. This is arguably the wrong thing to do, since we wouldn't
want to try to clean it up again. But:
- we can't call it as-is, because it calls free(), which we must avoid
in a signal handler (we'd have to pass in_signal so it can skip the
free() call)
- we'll only go through the list of children to clean once, since our
cleanup_children_on_signal() handler pops itself after running (and
then re-raises, so eventually we'd just exit). So this cleanup only
matters if a process is on the cleanup list _and_ it has a separate
handler to clean itself up. Which is questionable in the first place
(and AFAIK we do not do).
- double-cleanup isn't actually that bad anyway. waitpid() will just
return an error, which we won't even report because of in_signal.

This reverts commit f6526728f950cacfd5b5e42bcc65f2c47f3da654.
The change in f652672 (dir: select directories correctly, 2021-09-24)
caused a regression in directory-based matches with non-cone-mode
patterns, especially for .gitignore patterns. A test is included to
prevent this regression in the future.
The commit ed495847 (dir: fix pattern matching on dirs, 2021-09-24) was
reverted in 5ceb663 (dir: fix directory-matching bug, 2021-11-02) for
similar reasons. Neither commit changed tests, and tests added later in
the series continue to pass when these commits are reverted.

running our tests if this is not the case.
To remedy this we add the environment variable GIT_TEST_REQUIRE_PREREQ

prereq tests fail then the whole test run will abort.

When running the full test suite many tests can be skipped because of
missing prerequisites. It not easy right now to get an overview of which
ones are missing.
When switching to a new machine or environment some libraries and tools
might be missing or maybe a dependency broke completely. In this case
the tests would indicate nothing since all dependant tests are simply
skipped. This could hide broken behaviour or missing features in the
build. Therefore this patch summarizes the missing prereqs at the end of
the test run making it easier to spot such cases.
- Add failed prereqs to the test results.
- Aggregate and then show them with the totals.

When fetching, we send the incoming pack to index-pack (or
unpack-objects) via the sideband demuxer. If index-pack hits an error
(e.g., because an object fails fsck), then it will die immediately. This
may cause us to get SIGPIPE on the fetch, as we're still trying to write
pack contents from the sideband demuxer (which is typically a thread,
and thus takes down the whole fetch process).
You can see this in action with:
./t5702-protocol-v2.sh --stress --run=59
which ends with (wrapped for readability):
test_must_fail: died by signal 13: git -c protocol.version=2 \
-c transfer.fsckobjects=1 -c fetch.uriprotocols=http,https \
clone http://127.0.0.1:5708/smart/http_parent http_child
not ok 59 - packfile-uri with transfer.fsckobjects fails on bad object
This is mostly cosmetic. The actual error of interest (in this case, the
object that failed the fsck check) comes from index-pack straight to
stderr, so the user still sees it. They _might_ even see fetch-pack
complaining about index-pack failing, because the main thread is racing
with the sideband-demuxer. But they'll definitely see the signal death
in the exit code, which is what the test is complaining about.
We can make this more predictable by just ignoring SIGPIPE. The sideband
demuxer uses write_or_die(), so it will notice and stop (gracefully,
because we hook die_routine() to exit just the thread). And during this
section we're not writing anywhere else where we'd be concerned about
SIGPIPE preventing us from wasting effort writing to nowhere.

That call to memcpy() is in a conditional block that requires
REF_HAVE_NEW to be set. But in ref_transaction_update(), we make sure it
isn't set coming in:
if (flags & ~REF_TRANSACTION_UPDATE_ALLOWED_FLAGS)
BUG("illegal flags 0x%x passed to ref_transaction_update()", flags);
and then only set it if the variable isn't NULL:
flags |= (new_oid ? REF_HAVE_NEW : 0) | (old_oid ? REF_HAVE_OLD : 0);
So it should be impossible to reach that memcpy() with a NULL oid. But
for whatever reason, gcc doesn't accept that hitting the BUG() means we
won't go any further, even though it's marked with the noreturn
attribute. And the conditional is correct; ALLOWED_FLAGS doesn't contain
HAVE_NEW or HAVE_OLD, and you can even simplify it to check for those
flags explicitly and the compiler still complains.
We can work around this by just clearing the disallowed flags
explicitly. This should be a noop because of the BUG() check, but it
makes the compiler happy.

Let's change this to instead warn the user that the .git/ directory

The user.signingKey config for ssh signing supports either a path to a
file containing the key or for the sake of convenience a literal string
with the ssh public key. To differentiate between those two cases we
check if the first few characters contain "ssh-" which is unlikely to be
the start of a path. ssh supports other key types which are not prefixed
with "ssh-" and will currently be treated as a file path and therefore
fail to load. To remedy this we move the prefix check into its own
function and introduce the prefix `key::` for literal ssh keys. This way
we don't need to add new key types when they become available. The
existing `ssh-` prefix is retained for compatibility with current user
configs but removed from the official documentation to discourage its
use.

If writing a trace2 message fails, we optionally warn the user of this
fact. However, in 0ee10fd (usage: add trace2 entry upon warning(),
2020-11-23), we added a trace entry to the warning() function. This
means that we can enter an infinite loop of failing trace2 writes and
warnings. Fix this by disabling the failing trace2 destination before
issuing the warning.
Additionally, trace2 sets a default SIGPIPE handler
(tr2main_signal_handler) when it is initialized. This handler generates
its own trace2 messages when a signal is received. If a trace2 write
fails due to a broken pipe, this handler will run and then cause another
failed write. Fix this by temporarily ignoring SIGPIPE while writing
trace2 messages. This is safe because the write will still fail, and we
will disable the failing destination.

In a subsequent commit, we would like external-facing functions to be
able to accept "struct repository" and "struct branch" as a pair. This
is useful for functions like pushremote_for_branch(), which need to take
values from the remote_state and branch, even if branch == NULL.
However, a caller may supply an unrelated repository and branch, which
is not supported behavior.
To prevent misuse, add a die_on_missing_branch() helper function that
dies if a given branch is not from a given repository. Speed up the
existence check by replacing the branches list with a branches_hash
hashmap.
Like read_config(), die_on_missing_branch() is only called from
non-static functions; static functions are less prone to misuse because
they have strong conventions for keeping remote_state and branch in
sync.

To do so, move read_config() calls to non-static functions and create a

line) should push the refspecs in remote.remote-name.push. There is no
test case that checks this behavior in detached HEAD, so add one.

Now that the histogram algorithm calls xdl_classify_record() it is no
longer necessary to use xdl_recmatch() to compare lines, it is
sufficient just to compare the hash values. This has a negligible
effect on performance.

rindex and ha are only used by xdl_cleanup_records() which is not
called by the histogram or patience algorithms. The perf test results
show a small reduction in run time but that is probably within the
noise.

Histogram is the only diff algorithm not to call
xdl_classify_record(). xdl_classify_record() ensures that the hash
values of two strings that are not equal differ which means that it is
not necessary to use xdl_recmatch() when comparing lines, all that is
necessary is to compare the hash values. This gives a 7% reduction in
the runtime of "git log --patch" when using the histogram diff
algorithm.

The already-up-to-date pull bug was fixed for --ff-only but it did not
include the case where --ff or --ff-only are not specified. This updates
the --ff-only fix to include the case where --ff or --ff-only are not
specified in command line flags or config.

One of the tests in t5319 corrupts the checksum of the midx file by
writing a single 0xff over the final byte, and then confirms that we
detect the problem. This usually works fine, but would break if the
actual checksum ended with that same byte already.
It seems like this should happen in 1 out of 256 test runs, but it turns
out to be less often in practice. The contents of the midx are mostly
deterministic because it's based on the objects, and we remove most
sources of randomness by setting GIT_COMMITTER_DATE, etc. However,
there's still some randomness: some objects are duplicated between
packs, and the midx must decide which to use, which can be based on
timing.
So very occasionally we can end up with a real 0xff byte, and the test
fails. The most robust fix would be to read out the final byte and then
change it to something else (e.g., adding 1 mod 256). But that's awkward
to do in shell. Let's just blindly corrupt 10 bytes instead of 1, which
reduces our chances of an accidental noop to 1 in 2^80.

The "checkout" command is one of the main sources of leaks in the test
suite, let's fix the common ones by not leaking from the "struct
branch_info".
Doing this is rather straightforward, albeit verbose, we need to
xstrdup() constant strings going into the struct, and free() the ones
we clobber as we go along.
This also means that we can delete previous partial leak fixes in this
area, i.e. the "path_to_free" accounting added by 96ec7b1e708 (Convert
resolve_ref+xstrdup to new resolve_refdup function, 2011-12-13).
There was some discussion about whether "we should retain the "const
char *" here and cast at free() time, or have it be a "char *". Since
this is not a public API with any sort of API boundary let's use
"char *", as is already being done for the "refname" member of the
same struct.
The tests to mark as passing were found with:
rm .prove; GIT_SKIP_TESTS=t0027 prove -j8 --state=save t[0-9]*.sh :: --immediate
# apply & compile this change
prove -j8 --state=failed :: --immediate
I.e. the ones that were newly passing when the --state=failed command
was run. I left out "t3040-subprojects-basic.sh" and
"t4131-apply-fake-ancestor.sh" to to optimization-level related
differences similar to the ones noted in[1], except that these would
be something the current 'linux-leaks' job would run into.

There is a formatting issue in "multi-pack-index.html", corresponding
to the nesting bulleted list of a wrong usage in "multi-pack-index.txt"
and this commit fix the problem.
In ASCIIDOC, it doesn't treat an indented character as the
beginning of a sub-list. If we want to write a nested bulleted list, we
could just use ASTERISK without any DASH like:
"
* Level 1 list item
** Level 2 list item
*** Level 3 list item
** Level 2 list item
* Level 1 list item
** Level 2 list item
* Level 1 list item
"
The DASH can be used for bulleted list too, But the DASH is suggested
only to be used as the marker for the first level because the DASH
doesn’t work well or a best practice for nested lists,
like (dash is as level 2 below):
"
* Level 1 list item
- Level 2 list item
* Level 1 list item
"
ASTERISK is recommanded to use because it works intuitively and clearly
("marker length = nesting level") in nested lists, but the DASH can't.
However, when you want to write a non-nested bulleted lists, DASH works
too, like:
"
- Level 1 list item
- Level 1 list item
- Level 1 list item
"
