Rewrite of "git add -i" in C that appeared in Git 2.25 didn't
correctly record a removed file to the index, which is an old
regression but has become widely known because the C version
has become the default in the latest release.
Signed-off-by: Junio C Hamano <gitster@pobox.com>
The scripted version of `git add -i` used `git update-index --add
--remove`, but the built-in version implemented only the `--add` part.

"sudo git foo" used to consider a repository owned by the original
user a safe one to access; it now also considers a repository owned
by root a safe one, too (after all, if an attacker can craft a
malicious repository owned by root, the box is 0wned already).

git-compat-util: allow root to access both SUDO_UID and root owned
Previous changes introduced a regression which will prevent root for
accessing repositories owned by thyself if using sudo because SUDO_UID
takes precedence.
Loosen that restriction by allowing root to access repositories owned
by both uid by default and without having to add a safe.directory
exception.
A previous workaround that was documented in the tests is no longer
needed so it has been removed together with its specially crafted
prerequisite.

The code added 0cc05b044f (usage.c: add a non-fatal bug() function to go
with BUG(), 2022-06-02) sets up two va_list variables: one to output to
stderr, and one to trace2. But the order of initialization is wrong:
va_list ap, cp;
va_copy(cp, ap);
va_start(ap, fmt);
We copy the contents of "ap" into "cp" before it is initialized, meaning
it is full of garbage. The two should be swapped.
However, there's another bug, noticed by Johannes Schindelin: we forget
to call va_end() for the copy. So instead of just fixing the copy's
initialization, let's do two separate start/end pairs. This is allowed
by the standard, and we don't need to use copy here since we have access
to the original varargs. Matching the pairs with the calls makes it more
obvious that everything is being done correctly.
Note that we do call bug_fl() in the tests, but it didn't trigger this
problem because our format string doesn't have any placeholders. So even
though we were passing a garbage va_list through the stack, nobody ever
needed to look at it. We can easily adjust one of the trace2 tests to
trigger this, both for bug() and for BUG(). The latter isn't broken, but
it's nice to exercise both a bit more. Without the fix in this patch
(but with the test change), the bug() case causes a segfault.

Commit 5dccd9155f (t/perf: add iteration setup mechanism to perf-lib,
2022-04-04) modified the parameter parsing of test_wrapper() such that
the test title was no longer in $1, and is instead in $test_title_.
We correctly pass the new variable to the code which outputs the title
to the log, but missed the spot in test_wrapper() where the title is
written to the ".descr" file which is used to produce the final output
table. As a result, all of the titles are missing from that table (or
worse, using whatever was left in $1):

Add and use a LIBCURL prerequisite for tests added in
6dcbdc0d66 (remote: create fetch.credentialsInUrl config,
2022-06-06).
These tests would get as far as emitting a couple of the warnings we
were testing for, but would then die as we had no "git-remote-https"
program compiled.
It would be more consistent with other prerequisites (e.g. PERL for
NO_PERL) to name this "CURL", but since e9184b0789 (t5561: skip tests
if curl is not available, 2018-04-03) we've had that prerequisite
defined for checking of we have the curl(1) program.
The existing "CURL" prerequisite is only used in one place, and we
should probably name it "CURL_PROGRAM", then rename "LIBCURL" to
"CURL" as a follow-up, but for now (pre-v2.37.0) let's aim for the
most minimal fix possible.

Rename the "fetch.credentialsInUrl" configuration variable introduced
in 6dcbdc0d66 (remote: create fetch.credentialsInUrl config,
2022-06-06) to "transfer".
There are existing exceptions, but generally speaking the
"<namespace>.<var>" configuration should only apply to command
described in the "namespace" (and its sub-commands, so e.g. "clone.*"
or "fetch.*" might also configure "git-remote-https").
But in the case of "fetch.credentialsInUrl" we've got a configuration
variable that configures the behavior of all of "clone", "push" and
"fetch", someone adjusting "fetch.*" configuration won't expect to
have the behavior of "git push" altered, especially as we have the
pre-existing "{transfer,fetch,receive}.fsckObjects", which configures
different parts of the transfer dialog.
So let's move this configuration variable to the "transfer" namespace
before it's exposed in a release. We could add all of
"{transfer,fetch,pull}.credentialsInUrl" at some other time, but once
we have "fetch" configure "pull" such an arrangement would would be a
confusing mess, as we'd at least need to have "fetch" configure
"push" (but not the other way around), or change existing behavior.

Fix an issue that existed before 0527ccb1b5 (add -i: default to the
built-in implementation, 2021-11-30), but which became the default
with that change, we should not be marking tests that are known to
pass as "TODO" tests.
When GIT_TEST_ADD_I_USE_BUILTIN=1 was made the default we started
passing the tests added in 0f0fba2cc8 (t3701: add a test for advanced
split-hunk editing, 2019-12-06) and 1bf01040f0 (add -p: demonstrate
failure when running 'edit' after a split, 2015-04-16).
Thus we've been emitting this sort of output:
$ prove ./t3701-add-interactive.sh
./t3701-add-interactive.sh .. ok
All tests successful.
Test Summary Report
-------------------
./t3701-add-interactive.sh (Wstat: 0 Tests: 70 Failed: 0)

Which isn't just cosmetic, but due to issues with
test_expect_failure (see [1]) we could e.g. be hiding something as bad
as a segfault in the new implementation. It makes sense catch that,
especially before we put out a release with the built-in "add -i", so
let's generalize the check we were already doing in 0527ccb1b5 with a
new "ADD_I_USE_BUILTIN" prerequisite.

Fix a regression reported[1] against f443246b9f (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 96e7225b31 (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'

Extend the parallel execution API added in c553c72eed (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

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
0ec7c23cdc (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, afda36dbf3
(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.
