Whenever a user runs `git reflog expire --stale-fix`, the most likely
reason is that their repository is at least _somewhat_ corrupt. Which
means that it is more than just possible that some objects are missing.
If that is the case, that can currently let the command abort through
the phase where it tries to mark all reachable objects.
Instead of adding insult to injury, let's be gentle and continue as best
as we can in such a scenario, simply by ignoring the missing objects and
moving on.

"git worktree list" annotates each worktree according to its state such
as "prunable" or "locked", however it is not immediately obvious why
these worktrees are being annotated. For prunable worktrees a reason
is available that is returned by should_prune_worktree() and for locked
worktrees a reason might be available provided by the user via `lock`
command.
Let's teach "git worktree list" a --verbose mode that outputs the reason
why the worktrees are being annotated. The reason is a text that can take
virtually any size and appending the text on the default columned format
will make it difficult to extend the command with other annotations and
not fit nicely on the screen. In order to address this shortcoming the
annotation is then moved to the next line indented followed by the reason
If the reason is not available the annotation stays on the same line as
the worktree itself.
The output of "git worktree list" with verbose becomes like so:
$ git worktree list --verbose
...
/path/to/locked-no-reason acb124 [branch-a] locked
/path/to/locked-with-reason acc125 [branch-b]

The "git worktree list" command shows the absolute path to the worktree,
the commit that is checked out, the name of the branch, and a "locked"
annotation if the worktree is locked, however, it does not indicate
whether the worktree is prunable.
The "prune" command will remove a worktree if it is prunable unless
`--dry-run` option is specified. This could lead to a worktree being
removed without the user realizing before it is too late, in case the
user forgets to pass --dry-run for instance. If the "list" command shows
which worktree is prunable, the user could verify before running
"git worktree prune" and hopefully prevents the working tree to be
removed "accidentally" on the worse case scenario.
Let's teach "git worktree list" to show when a worktree is a prunable
candidate for both default and porcelain format.
In the default format a "prunable" text is appended:
$ git worktree list
/path/to/main aba123 [main]
/path/to/linked 123abc [branch-a]
/path/to/prunable ace127 (detached HEAD) prunable
In the --porcelain format a prunable label is added followed by
its reason:
$ git worktree list --porcelain
...
worktree /path/to/prunable
HEAD abc1234abc1234abc1234abc1234abc1234abc12

Commit c57b3367be (worktree: teach `list` to annotate locked worktree,
2020-10-11) taught "git worktree list" to annotate locked worktrees by
appending "locked" text to its output, however, this is not listed in
the --porcelain format.
Teach "list --porcelain" to do the same and add a "locked" attribute
followed by its reason, thus making both default and porcelain format
consistent. If the locked reason is not available then only "locked"
is shown.
The output of the "git worktree list --porcelain" becomes like so:
$ git worktree list --porcelain
...
worktree /path/to/locked
HEAD 123abcdea123abcd123acbd123acbda123abcd12

worktree /path/to/locked-with-reason
HEAD abc123abc123abc123abc123abc123abc123abc1
detached
locked reason why it is locked
...
In porcelain mode, if the lock reason contains special characters
such as newlines, they are escaped with backslashes and the entire
reason is enclosed in double quotes. For example:
$ git worktree list --porcelain
...
locked "worktree's path mounted in\nremovable device"
...
Furthermore, let's update the documentation to state that some
attributes in the porcelain format might be listed alone or together
with its value depending whether the value is available or not. Thus
documenting the case of the new "locked" attribute.

with "locked" annotation. However, the test does not clean up after
itself as "git worktree prune" is not going to remove the locked worktree
in the first place. This not only leaves the test in an unclean state it
also potentially breaks following tests that rely on the

it's better to set a good example.
We can use:
perl -ne 'print if $. % 5 == 1'
instead. But we can further observe that perl does a good job of the

When we expand a user-format, we try to avoid work that isn't necessary
for the output. For instance, we don't bother parsing the commit header
until we know we need the author, subject, etc.
But we do always load the commit object's contents from disk, even if
the format doesn't require it (e.g., just "%H"). Traditionally this
didn't matter much, because we'd have loaded it as part of the traversal
anyway, and we'd typically have those bytes attached to the commit
struct (or these days, cached in a commit-slab).
But when we have a commit-graph, we might easily get to the point of
pretty-printing a commit without ever having looked at the actual object
contents. We should push off that load (and reencoding) until we're
certain that it's needed.
I think the results of p4205 show the advantage pretty clearly (we serve
parent and tree oids out of the commit struct itself, so they benefit as
well):

In 6e98de72c0 (sequencer (rebase -i): add support for the 'fixup' and
'squash' commands, 2017-01-02), this developer introduced a change of
behavior by mistake: when encountering a `fixup!` commit (or multiple
`fixup!` commits) without any `squash!` commit thrown in, the final `git
commit` was invoked with `--cleanup=strip`. Prior to that commit, the
commit command had been called without that `--cleanup` option.
Since we explicitly read the original commit message from a file in that
case, there is really no sense in forcing that clean-up.
We actually need to actively suppress that clean-up lest a configured
`commit.cleanup` may interfere with what we want to do: leave the commit
message unchanged.

When we use the sub-test helpers, we end up defining one shell snippet
inside another shell snippet. So if we use single-quotes for the outer
snippet, we have to use double-quotes within the inner snippet (it's
included as here-doc within the outer snippet, but using a single quote
would end the outer snippet early). Or vice versa we can use double
quotes for the outer snippet, but then single quotes in the inner.
We have some of each in the script, and neither is wrong. But it would
be nice to be consistent unless there is a good reason not to. Using
single quotes for the outer script is preferable, because it requires
less metacharacter quoting overall. For example, in:
test_expect_success 'outer' '
run_sub_test_lib_test ... <<-\EOF
echo $foo &&
test_expect_success "inner" "
echo \$bar
"
EOF
'
we need only quote inside "inner", but not inside "outer" or the
here-doc. Whereas if we flip them, we have to quote in both places:
test_expect_success 'outer' "
run_sub_test_lib_test ... <<-\EOF
echo \$foo &&
test_expect_success 'inner' '
echo \$bar
'
EOF
"
The exception is when we need a literal single-quote in an expected
output here-doc. There we can either use outer double-quotes, or just
use ${SQ} within the doc. I chose the latter for consistency (within
this test, but also with other test scripts that face the same problem).
There is one other interesting case, which is some tests that do:
test_expect_success ... "
do_something --run='"'!3'"'
"
This is rather confusing to read, but is correct. The outer script sees
'!3' in single-quotes, as does the eval'd snippet. This is perhaps being
overly cautious. In many interactive shells, an exclamation triggers
history expansion even inside double quotes, but that is not generally
true in non-interactive shells.
There's some conflicting information here. Commit 784ce03d55 (t4216:
avoid unnecessary subshell in test_bloom_filters_not_used, 2020-05-19)
reports it as a problem with OpenBSD 6.7's /bin/sh. However, we have
many instances in this script of prereqs like !LAZY_TRUE, which haven't
been a problem. I left them un-escaped here to test out this theory.
It's much nicer if we can not worry about this as a portability issue,
so it's worth knowing.

Our check of test_when_finished is done directly in the main script, and
if we failed to clean, we complain and exit immediately. It's nicer to
signal a test failure here, for a few reasons:
- this gives better output to the user when run under a TAP harness
like "prove"
- constency; it's the only test left in the file that behaves this way
- half of its "if" conditional is nonsense anyway; it picked up a
reference to GIT_TEST_FAIL_PREREQS_INTERNAL in dfe1a17df9 (tests:
add a special setup where prerequisites fail, 2019-05-13) along with
its neighbors, even though it has nothing to do with that flag
We could actually do this without a sub-test at all, and just put our
two tests (one to do cleanup, and one to check that it happened) in the
main script. But doing it in a subtest is conceptually cleaner (from the
perspective of the main test script, we are checking only one thing),
and it remains consistent with the "cleanup when failing" test directly
after it, which has to happen in a sub-test (to avoid the main script
complaining of the failed test).

We test the behavior of prerequisites in t0000 by setting up fake ones
in the main test script, trying to run some tests, and then seeing if
those tests impacted the environment correctly. If they didn't, then we
write a message and manually call exit.
Instead, let's push these down into a sub-test, like many of the other
tests covering the framework itself. This has a few advantages:
- it does not pollute the test output with mention of skipped tests
(that we know are uninteresting -- the point of the test was to see
that these are skipped).
- when running in a TAP harness, we get a useful test failure message
(whereas when the script exits early, a tool like "prove" simply
says "Dubious, test returned 1").
- we do not have to worry about different test environments, such as
when GIT_TEST_FAIL_PREREQS_INTERNAL is set. Our sub-test helpers
already give us a known environment.
- the tests themselves are a bit easier to read, as we can just check
the test-framework output to see what happened (and get the usual
test_cmp diff if it failed)
A few notes on the implementation:
- we could do one sub-test per each individual test_expect_success. I
broke it up here into a few logical groups, as I think this makes it
more readable
- the original tests modified environment variables inside the test
bodies. Instead, I've used "true" as the body of a test we expect to
run and "false" otherwise. Technically this does not confirm that
the body of the "true" test actually ran. We are trusting the
framework output to believe that it truly ran, which is sufficient
for these tests. And I think the end result is much simpler to
follow.
- the nested_prereq test uses a few bare "test -f" calls; I converted
these to our usual test_path_is_* helpers while moving the code
around.

'./t1234-foo.sh --stress-jobs=X ...' is supposed to run that test
script in X parallel jobs, but the number of jobs specified on the
command line is entirely ignored if other '--stress'-related options
follow. I.e. both './t1234-foo.sh --stress-jobs=X --stress-limit=Y'
and './t1234-foo.sh --stress-jobs=X --stress' fall back to using twice
the number of CPUs parallel jobs instead.
The former has been broken since commit de69e6f6c9 (tests: let
--stress-limit=<N> imply --stress, 2019-03-03) [1], which started to
unconditionally overwrite the $stress variable holding the specified
number of jobs in its effort to imply '--stress'. The latter has been
broken since f545737144 (tests: introduce --stress-jobs=<N>,
2019-03-03), because it didn't consider that handling '--stress' will
overwrite that variable as well.
We could fix this by being more careful about (over)writing that
$stress variable and checking first whether it has already been set.
But I think it's cleaner to use a dedicated variable to hold the
number of specified parallel jobs, so let's do that instead.
[1] In de69e6f6c9 there was no '--stress-jobs=X' option yet, the
number of parallel jobs had to be specified via '--stress=X', so,
strictly speaking, de69e6f6c9 broke './t1234-foo.sh --stress=X
--stress-limit=Y'.

"git diff" showed a submodule working tree with untracked cruft as
"Submodule commit <objectname>-dirty", but a natural expectation is
that the "-dirty" indicator would align with "git describe --dirty",
which does not consider having untracked files in the working tree
as source of dirtiness. The inconsistency has been fixed.

Improve the support for invalid UTF-8 haystacks given a non-ASCII
needle when using the PCREv2 backend.
This is a more complete fix for a bug I started to fix in
870eea8166 (grep: do not enter PCRE2_UTF mode on fixed matching,
2019-07-26), now that PCREv2 has the PCRE2_MATCH_INVALID_UTF mode we
can make use of it.
This fixes the sort of case described in 8a5999838e (grep: stess test
PCRE v2 on invalid UTF-8 data, 2019-07-26), i.e.:
- The subject string is non-ASCII (e.g. "ævar")
- We're under a is_utf8_locale(), e.g. "en_US.UTF-8", not "C"
- We are using --ignore-case, or we're a non-fixed pattern
If those conditions were satisfied and we matched found non-valid
UTF-8 data PCREv2 might bark on it, in practice this only happened
under the JIT backend (turned on by default on most platforms).
Ultimately this fixes a "regression" in b65abcafc7 ("grep: use PCRE v2
for optimized fixed-string search", 2019-07-01), I'm putting that in
scare-quotes because before then we wouldn't properly support these
complex case-folding, locale etc. cases either, it just broke in
different ways.
There was a bug related to this the PCRE2_NO_START_OPTIMIZE flag fixed
in PCREv2 10.36. It can be worked around by setting the
PCRE2_NO_START_OPTIMIZE flag. Let's do that in those cases, and add
tests for the bug.

As noted in [1] when I originally added this test in [2] the test was
completely broken as it lacked a redirect[3]. I now think this whole
thing is overly fragile. Let's only test if we have a segfault here.
Before this the first test's "test_cmp" was pretty meaningless. We
were only testing if PCREv2 was so broken that it would spew out
something completely unrelated on stdout, which isn't very plausible.
In the second test we're relying on PCREv2 forever holding to the
current behavior of the PCRE_UTF8 flag, as opposed to learning some
optimistic graceful fallback to PCRE2_MATCH_INVALID_UTF in the
future. If that happens having this test broken under bisecting would
suck.
A follow-up commit will actually test this case in a meaningful way
under the PCRE2_MATCH_INVALID_UTF flag. Let's run this one
unconditionally, and just make sure we don't segfault.

Remove support for using version 1 of the PCRE library. Its use has
been discouraged by upstream for a long time, and it's in a
bugfix-only state.
Anyone who was relying on v1 in particular got a nudge to move to v2
in e6c531b808 (Makefile: make USE_LIBPCRE=YesPlease mean v2, not v1,
2018-03-11), which was first released as part of v2.18.0.
With this the LIBPCRE2 test prerequisites is redundant to PCRE. But
I'm keeping it for self-documentation purposes, and to avoid conflict
with other in-flight PCRE patches.
I'm also not changing all of our own "pcre2" names to "pcre", i.e. the
inverse of 6d4b5747f0 (grep: change internal *pcre* variable &
function names to be *pcre1*, 2017-05-25). I don't see the point, and
it makes the history/blame harder to read. Maybe if there's ever a
PCRE v3...

These also document some behaviors that differ from a full checkout, and
possibly in a way that is not intended.
The test is designed to be run with "--run=1,X" where 'X' is an
interesting test case. Each test uses 'init_repos' to reset the full and
sparse copies of the initial-repo that is created by the first test
case. This also makes it possible to have test cases leave the working
directory or index in unusual states without disturbing later cases.

Subject: [PATCH 8/9] test-lib: test_region looks for trace2 regions
Most test cases can verify Git's behavior using input/output
expectations or changes to the .git directory. However, sometimes we
want to check that Git did or did not run a certain section of code.
This is particularly important for performance-only features that we
want to ensure have been enabled in certain cases.
Add a new 'test_region' function that checks if a trace2 region was
entered and left in a given trace2 event log.
There is one existing test (t0500-progress-display.sh) that performs
this check already, so use the helper function instead. Note that this
changes the expectations slightly. The old test (incorrectly) used two
patterns for the 'grep' invocation, but this performs an OR of the
patterns, not an AND. This means that as long as one region_enter event
was logged, the test would succeed, even if it was not due to the
progress category.
More uses will be added in a later change.
t6423-merge-rename-directories.sh also greps for region_enter lines, but
it verifies the number of such lines, which is not the same as an
existence check.
