Because of the wrapping of the branch name variable $b, the colour codes
in the variable don't get applied, but are instead printed directly in
the output. Move the wrapping of $b to before colour codes are inserted
to correct this. Revert move of branch name colour codes in tests, as
the branch name is now coloured after the wrapping instead of before.

The resolve-undo extension was added to the index in cfc5789a
(resolve-undo: record resolved conflicts in a new index extension
section, 2009-12-25). This extension records the blob object names
and their modes of conflicted paths when the path gets resolved
(e.g. with "git add"), to allow "undoing" the resolution with
"checkout -m path". These blob objects should be guarded from
garbage-collection while we have the resolve-undo information in the
index (otherwise unresolve operation may try to use a blob object
that has already been pruned away).
But the code called from mark_reachable_objects() for the index
forgets to do so. Teach add_index_objects_to_pending() helper to
also add objects referred to by the resolve-undo extension.
Also make matching changes to "fsck", which has code that is fairly
similar to the reachability stuff, but have parallel implementations
for all these stuff, which may (or may not) someday want to be unified.

Using `ssh-add -L` for gpg.ssh.defaultKeyCommand is not a good
recommendation. It might switch keys depending on the order of known
keys and it only supports ssh-* and no ecdsa or other keys.
Clarify that we expect a literal key prefixed by `key::`, give valid
example use cases and refer to `user.signingKey` as the preferred

Git now shows better information in the GitHub workflow runs when a test
case failed. However, when a test case was implemented incorrectly and
therefore does not even run, nothing is shown.
Let's bring back the step that prints the full logs of the failed tests,
and to improve the user experience, print out an informational message
for readers so that they do not have to know/remember where to see the

In rare cases[1], wait_or_whine() cannot determine a child process's
status (and will return -1 in this case). This can cause Git to issue
trace2 child_exit events despite the fact that the child may still be
running. In pathological cases, we've seen > 80 million exit events in
our trace logs for a single child process.
Fix this by only issuing trace2 events in finish_command_in_signal() if
we get a value other than -1 from wait_or_whine(). This can lead to
missing child_exit events in such a case, but that is preferable to
duplicating events on a scale that threatens to fill the user's
filesystem with invalid trace logs.
[1]: This can happen when:
* waitpid() returns -1 and errno != EINTR
* waitpid() returns an invalid PID
* the status set by waitpid() has neither the WIFEXITED() nor
WIFSIGNALED() flags

Fix a regression reported[1] against f443246b9f2 (commit: convert
{pre-commit,prepare-commit-msg} hook to hook.h, 2021-12-22): Due to
using the run_process_parallel() API in the earlier 96e7225b310 (hook:
add 'run' subcommand, 2021-12-22) we'd capture the hook's stderr and
stdout, and thus lose the connection to the TTY in the case of
e.g. the "pre-commit" hook.
As a preceding commit notes GNU parallel's similar --ungroup option
also has it emit output faster. While we're unlikely to have hooks
that emit truly massive amounts of output (or where the performance
thereof matters) it's still informative to measure the overhead. In a
similar "seq" test we're now ~30% faster:
$ cat .git/hooks/seq-hook; git hyperfine -L rev origin/master,HEAD~0 -s 'make CFLAGS=-O3' './git hook run seq-hook'
#!/bin/sh
seq 100000000

Fix a bug in fd3cb0501e1 (remote: move static variables into

after having NULL'd out remote->pushurl. itself. We free
"remote->pushurl" in the next "for"-loop, so doing this appears to
have been a copy/paste error.

dereference NULL in this case, this change fixes that:

Extend the parallel execution API added in c553c72eed6 (run-command:
add an asynchronous parallel child processor, 2015-12-15) to support a
mode where the stdout and stderr of the processes isn't captured and
output in a deterministic order, instead we'll leave it to the kernel
and stdio to sort it out.
This gives the API same functionality as GNU parallel's --ungroup
option. As we'll see in a subsequent commit the main reason to want
this is to support stdout and stderr being connected to the TTY in the
case of jobs=1, demonstrated here with GNU parallel:
$ parallel --ungroup 'test -t {} && echo TTY || echo NTTY' ::: 1 2
TTY
TTY
$ parallel 'test -t {} && echo TTY || echo NTTY' ::: 1 2
NTTY
NTTY
Another is as GNU parallel's documentation notes a potential for
optimization. As demonstrated in next commit our results with "git
hook run" will be similar, but generally speaking this shows that if
you want to run processes in parallel where the exact order isn't
important this can be a lot faster:
$ hyperfine -r 3 -L o ,--ungroup 'parallel {o} seq ::: 10000000 >/dev/null '
Benchmark 1: parallel seq ::: 10000000 >/dev/null
Time (mean ± σ): 220.2 ms ± 9.3 ms [User: 124.9 ms, System: 96.1 ms]
Range (min … max): 212.3 ms … 230.5 ms 3 runs
Benchmark 2: parallel --ungroup seq ::: 10000000 >/dev/null
Time (mean ± σ): 154.7 ms ± 0.9 ms [User: 136.2 ms, System: 25.1 ms]
Range (min … max): 153.9 ms … 155.7 ms 3 runs
Summary
'parallel --ungroup seq ::: 10000000 >/dev/null ' ran
1.42 ± 0.06 times faster than 'parallel seq ::: 10000000 >/dev/null '
A large part of the juggling in the API is to make the API safer for
its maintenance and consumers alike.
For the maintenance of the API we e.g. avoid malloc()-ing the
"pp->pfd", ensuring that SANITIZE=address and other similar tools will
catch any unexpected misuse.
For API consumers we take pains to never pass the non-NULL "out"
buffer to an API user that provided the "ungroup" option. The
resulting code in t/helper/test-run-command.c isn't typical of such a
user, i.e. they'd typically use one mode or the other, and would know
whether they'd provided "ungroup" or not.
We could also avoid the strbuf_init() for "buffered_output" by having
"struct parallel_processes" use a static PARALLEL_PROCESSES_INIT
initializer, but let's leave that cleanup for later.
Using a global "run_processes_parallel_ungroup" variable to enable
this option is rather nasty, but is being done here to produce as
minimal of a change as possible for a subsequent regression fix. This
change is extracted from a larger initial version[1] which ends up
with a better end-state for the API, but in doing so needed to modify
all existing callers of the API. Let's defer that for now, and
narrowly focus on what we need for fixing the regression in the
subsequent commit.
It's safe to do this with a global variable because:
A) hook.c is the only user of it that sets it to non-zero, and before
we'll get any other API users we'll refactor away this method of
passing in the option, i.e. re-roll [1].
B) Even if hook.c wasn't the only user we don't have callers of this
API that concurrently invoke this parallel process starting API
itself in parallel.
As noted above "A" && "B" are rather nasty, and we don't want to live
with those caveats long-term, but for now they should be an acceptable
compromise.

The short upstream state indicator inherits the colour of the last short
state indicator before it (if there is one), and the sparsity state
indicator inherits this colour as well. This behaviour was introduced by
0ec7c23cdc6 (git-prompt: make upstream state indicator location
consistent, 2022-02-27), while before this change the aforementioned
indicators were white/the default text colour. Some examples to
illustrate this behaviour (assuming all indicators are enabled and
colourization is on):
* If there is something in the stash, both the '$' and the short
upstream state indicator following it will be blue.
* If the local tree has new, untracked files and there is nothing in
the stash, both the '%' and the short upstream state indicator
will be red.
* If all local changes are added to the index and the stash is empty,
both the '+' and the short upstream state indicator following it will
be green.
* If the local tree is clean and there is nothing in the stash, the
short upstream state indicator will be white/${default text colour}.
This appears to be an unintended side-effect of the change, and makes
little sense semantically (e.g. why is it bad to be in sync with
upstream when you have uncommitted local changes?). The cause of the
change in colourization is that previously, the short upstream state
indicator appeared immediately after the rebase/revert/bisect/merge
state indicator (note the position of $p in $gitstring):
local f="$h$w$i$s$u"
local gitstring="$c$b${f:+$z$f}${sparse}$r$p"
Said indicator is prepended with the clear colour code, and the short
upstream state indicator is thus also uncoloured. Now, the short
upstream state indicator follows the sequence of colourized indicators,
without any clearing of colour (again note the position of $p, now in
$f):
local f="$h$w$i$s$u$p"
local gitstring="$c$b${f:+$z$f}${sparse}$r${upstream}"
If the user is in a sparse checkout, the sparsity state indicator
follows a similar pattern to the short upstream state indicator.
However, clearing colour of the colourized indicators changes how the
sparsity state indicator is colourized, as it currently inherits (and
before the change referenced also inherited) the colour of the last
short state indicator before it. Reading the commit message of the
change that introduced the sparsity state indicator, afda36dbf3b
(git-prompt: include sparsity state as well, 2020-06-21), it appears
this colourization also was unintended, so clearing the colour for said
indicator further increases consistency.
Make the colourization of these state indicators consistent by making
all colourized indicators clear their own colour. Make colouring of $c
dependent on it not being empty, as it is no longer being used to colour
the branch name. Move clearing of $b's prefix to before colourization so
it gets cleared properly when colour codes are inserted into it. These
changes make changing the layout of the prompt less prone to unintended
colour changes in the future.
Change coloured Bash prompt tests to reflect the colourization changes:
* Move the colour codes to wrap the expected content of the expanded
$__git_ps1_branch_name in all tests.
* Insert a clear-colour code after the symbol for the first indicator
in "prompt - bash color pc mode - dirty status indicator - dirty
index and worktree", to reflect that all indicators should clear
their own colour.

After generating diffs for each range to be compared using a 'git log'
invocation, range-diff.c::read_patches looks for the "diff --git" header
in those diffs to recognize the beginning of a new change.
In a project with submodules, and with 'diff.submodule=log' set in the
config, this header is missing for the diff of a changed submodule, so
any submodule changes are quietly ignored in the range-diff.
When 'diff.submodule=diff' is set in the config, the "diff --git" header
is also missing for the submodule itself, but is shown for submodule
content changes, which can easily confuse 'git range-diff' and lead to
errors such as:
error: git apply: bad git-diff - inconsistent old filename on line 1
error: could not parse git header 'diff --git path/to/submodule/and/some/file/within
'
error: could not parse log for '@{u}..@{1}'
Force the submodule diff format to its default ("short") when invoking
'git log' to generate the patches for each range, such that submodule
changes are always detected.
Add a test, including an invocation with '--creation-factor=100' to
force the second commit in the range not to be considered a complete
rewrite, in order to verify we do indeed get the "short" format.

Change those tests that assumed that a .git/info directory would be
created for them when writing .git/info/exclude to explicitly create
the directory by setting "TEST_CREATE_REPO_NO_TEMPLATE=1" before
sourcing test-lib.sh, and using the "--template=" argument to "git
clone" and "git init".
In the case of ".git/modules/sub1/info" we deviate from the
established pattern in this and preceding commits of passing a
"--template=" and doing a "mkdir .git/info".
In that case "git checkout" will run the "submodule--helper clone",
and both e.g. "git submodule update --init" and "git checkout" do not
have a way to pass down options to the eventual "git init" or "git
clone". Let's instead assume that the submodule was populated with our
default templates, remove them, and then run the "mkdir".

Change those tests that assumed that a .git/info directory would be
created for them when writing .git/info/attributes to explicitly
create the directory by setting "TEST_CREATE_REPO_NO_TEMPLATE=1"
before sourcing test-lib.sh, and using the "--template=" argument to
"git clone".
The change here in here in t7814-grep-recurse-submodules.sh would
continue "succeeding" with only the "TEST_CREATE_REPO_NO_TEMPLATE=1"
part of this change. That's because those tests use
"test_expect_failure", so they'd "pass" without this change, as
"test_expect_failure" by design isn't discerning about what failure
conditions it'll accept.
But as we're fixing these sorts of issues across the test suite let's
fix this one too. This issue was spotted with a local merge with
another topic of mine[1], which introduces a stricter alternative to
"test_expect_failure".

Change those tests that assumed that a .git/info directory would be
created for them when writing .git/info/grafts to explicitly create
the directory.
Do this using the new "TEST_CREATE_REPO_NO_TEMPLATE" facility, and use
"mkdir" instead of "mkdir -p" to assert that we don't have the
.git/info already. An exception to this is the "with grafts" test in
"t6001-rev-list-graft.sh". There we're modifying our ".git" state in a
for-loop, in lieu of refactoring that more extensively let's use
"mkdir -p" there.

As noted in c8a58ac5a52 (Revert "Don't create the $GIT_DIR/branches
directory on init", 2009-10-31) there was an attempt long ago in
0cc5691a8b0 (Don't create the $GIT_DIR/branches directory on init,
2009-10-30) to get rid of the legacy "branches" directory.
We should probably get rid of its creation by removing the
"templates/branches--" file. But whatever our default behavior, our
tests should be tightened up to explicitly create the .git/branches
directory if they rely on our default templates, to make the
dependency on those templates clear.
So let's amend the two tests that would fail if .git/branches wasn't
created. To do this introduce a new "TEST_CREATE_REPO_NO_TEMPLATE"
variable, which we'll set before sourcing test-lib.sh, and change the
"git clone" and "git init" commands in the tests themselves to
explicitly pass "--template=".
This way they won't get a .git/branches in either their top-level
.git, or in the ones they create. We can then amend the tests that
rely on the ".git/branches" directory existing to create it
explicitly, and to remove it after its creation.
This new "TEST_CREATE_REPO_NO_TEMPLATE" variable is a less
heavy-handed version of the "NO_SET_GIT_TEMPLATE_DIR" variable. See
a94d305bf80 (t/t0001-init.sh: add test for 'init with init.templatedir
set', 2010-02-26) for its implementation.
Unlike "TEST_CREATE_REPO_NO_TEMPLATE", this new
"TEST_CREATE_REPO_NO_TEMPLATE" variable is narrowly scoped to what the
"git init" in test-lib.sh does, as opposed to the global effect of
"NO_SET_GIT_TEMPLATE_DIR" and the setting of "GIT_TEMPLATE_DIR" in
wrap-for-bin.sh.
I experimented with adding a new "GIT_WRAP_FOR_BIN_VIA_TEST_LIB"
variable set in test-lib.sh, which would cause wrap-for-bin.sh to not
set GIT_TEMPLATE_DIR, GITPERLLIB etc, as we set those in
test-lib.sh. I think that's a viable approach, but it would interact
e.g. with the appending feature of GITPERLLIB added in
8bade1e12e2 (wrap-for-bin: make bin-wrappers chainable, 2013-07-04).
Doing so would allow us to convert the tests in t0001-init.sh that now
use "NO_SET_GIT_TEMPLATE_DIR" to simply unset "GIT_TEMPLATE_DIR" in a
sub-shell before invoking "git init" or "git clone". I think that
approach is worth pursuing, but let's table it for now. Some future
wrap-for-bin.sh refactoring can try to address it.

Change a test added in 368aa52952d (add git-check-ignore sub-command,
2013-01-06) to clobber .git/info/exclude rather than append to
it.
These tests would break if the "templates/info--exclude" file added in
d3af621b147 (Redo the templates generation and installation.,
2005-08-06) wasn't exactly 6 lines (of only comments).
Let's instead clobber the default .git/info/excludes file, and test
only our own expected content. This is not strictly needed for
anything in this series, but is a good cleanup while we're at it.
As discussed in the preceding commit a lot of things depend on the
"info" directory being created, but this was the only test that relied
on the specific content in the "templates/info--exclude" file.

When a commit is parsed, it pretends to have a different (possibly
empty) list of parents if there is graft information for that commit.
But there is a bug that could occur when a commit is parsed, the graft
information is updated (for example, when a shallow file is rewritten),
and the same commit is subsequently used: the parents of the commit do
not conform to the updated graft information, but the information at the
time of parsing.
This is usually not an issue, as a commit is usually introduced into the
repository at the same time as its graft information. That means that
when we try to parse that commit, we already have its graft information.
But it is an issue when fetching a shallow point directly into a
repository with submodules. The function
assign_shallow_commits_to_refs() parses all sought objects (including
the shallow point, which we are directly fetching). In update_shallow()
in fetch-pack.c, assign_shallow_commits_to_refs() is called before
commit_shallow_file(), which means that the shallow point would have
been parsed before graft information is updated. Once a commit is
parsed, it is no longer sensitive to any graft information updates. This
parsed commit is subsequently used when we do a revision walk to search
for submodules to fetch, meaning that the commit is considered to have
parents even though it is a shallow point (and therefore should be
treated as having no parents).
Therefore, whenever graft information is updated, mark the commits that
were previously grafts and the commits that are newly grafts as
unparsed.
