Many of our commands support reading input that is separated either via
newlines or via NUL characters. Furthermore, in order to be a better
cross platform citizen, these commands typically know to strip the CRLF
sequence so that we also support reading newline-separated inputs on
e.g. the Windows platform. This results in the following kind of awkward
pattern:
```
struct strbuf input = STRBUF_INIT;
while (1) {
int ret;
if (nul_terminated)
ret = strbuf_getline_nul(&input, stdin);
else
ret = strbuf_getline(&input, stdin);
if (ret)
break;
...
}
```
Introduce a new CRLF-aware helper function that can read up to a user
specified delimiter. If the delimiter is `\n` the function knows to also
strip CRLF, otherwise it will only strip the specified delimiter. This
results in the following, much more readable code pattern:
```
struct strbuf input = STRBUF_INIT;
while (strbuf_getdelim_strip_crlf(&input, stdin, delim) != EOF) {
...
}
```
The new function will be used in a subsequent commit.

The tests for git-cat-file(1) are quite old and haven't ever been
updated since they were introduced. They thus tend to use old idioms
that have since grown outdated. Most importantly, many of the tests use
`test $A = $B` to compare expected and actual output. This has the
downside that it is impossible to tell what exactly is different between
both versions in case the test fails.
Refactor the tests to instead use `test_cmp`. While more verbose, it
both tends to be more readable and will result in a nice diff in case
states don't match.

In t1006 we have a bunch of tests that verify the output format of the
git-cat-file(1) command. But while part of the output for some tests
would include commit timestamps, we don't verify those but instead strip
them before comparing expected with actual results. This is done by the
function `maybe_remove_timestamp`, which goes all the way back to the
ancient commit b335d3f121 (Add tests for git cat-file, 2008-04-23).
Our tests had been in a different shape back then. Most importantly we
didn't yet have the infrastructure to create objects with deterministic
timestamps. Nowadays we do though, and thus there is no reason anymore
to strip the timestamps.
Refactor the tests to not strip the timestamp anymore.

The index is read in 'worktree.c' at two points:
1.The 'validate_no_submodules' function, which checks if there are any
submodules present in the worktree.
2.The 'check_clean_worktree' function, which verifies if a worktree is
'clean', i.e., there are no untracked or modified but uncommitted files.
This is done by running the 'git status' command, and an error message
is thrown if the worktree is not clean. Given that 'git status' is
already sparse-aware, the function is also sparse-aware.
Hence we can just set the requires-full-index to false for
"git worktree".
Add tests that verify that 'git worktree' behaves correctly when the
sparse index is enabled and test to ensure the index is not expanded.
The `p2000` tests demonstrate a ~20% execution time reduction for
'git worktree' using a sparse index:
(Note:the p2000 test results didn't reflect the huge speedup because of
the index reading time is minuscule comparing to the filesystem
operations.)

We don't really care about the specific message text all that much here.
Use grep and a single regex with alternations to ascertain that we get
an error message (fatal or otherwise) about the failed invocation of the
hook, but don't bother checking if we get the right variant for the
platform the test is running on or whether quoting is done. This looser
check let's the test pass on NonStop OS.

Subject: [PATCH v2 2/2] add: test use of brackets when color is disabled
The interactive add command, 'git add -i', displays a menu of options
using full words. When color is enabled, the first letter of each word
is changed to a highlight color to signal that the first letter could be
used as a command. Without color, brackets ("[]") are used around these
first letters.
This behavior was not previously tested directly in t3701, so add a test
for it now. Since we use 'git add -i >actual <input' without
'force_color', the color system recognizes that colors are not available
on stdout and will be disabled by default.
This test would reproduce correctly with or without the fix in the
previous commit to make sure that color.ui is respected in 'git add'.

When 'git add -i' and 'git add -p' were converted to a builtin, they
introduced a color bug: the 'color.ui' config setting is ignored.
The included test demonstrates an example that is similar to the
previous test, which focuses on customizing colors. Here, we are
demonstrating that colors are not being used at all by comparing the raw
output and the color-decoded version of that output.
The fix is simple, to use git_color_default_config() as the fallback for
git_add_config(). A more robust change would instead encapsulate the
git_use_color_default global in methods that would check the config
setting if it has not been initialized yet. Some ideas are being
discussed on this front [1], but nothing has been finalized.
[1] https://lore.kernel.org/git/pull.1539.git.1685716420.gitgitgadget@gmail.com/
This test case naturally bisects down to 0527ccb1b5 (add -i: default to
the built-in implementation, 2021-11-30), but the fix makes it clear
that this would be broken even if we added the config to use the builtin
earlier than this.

Since the linux-asan-ubsan job runs using clang under Linux, there is
not much point in running a separate clang job. Any errors that a normal
clang compile-and-test cycle would find are likely to be a subset of
what the sanitizer job will find. Since this job takes ~14 minutes to
run in CI, this shaves off some of our CPU load (though it does not
affect end-to-end runtime, since it's typically run in parallel and is
not the longest job).
Technically this provides us with slightly less signal for a given run,
since you won't immediately know if a failure in the sanitizer job is
from using clang or from the sanitizers themselves. But it's generally
obvious from the logs, and anyway your next step would be to fix the
probvlem and re-run CI, since we expect all of these jobs to pass
normally.

When we started running sanitizers in CI via 1c0962c0c4 (ci: add address
and undefined sanitizer tasks, 2022-10-20), we ran them as two separate
CI jobs, since as that commit notes, the combination "seems to take
forever".
And indeed, it does with gcc. However, since the previous commit
switched to using clang, the situation is different, and we can save
some CPU by using a single job for both. Comparing before/after CI runs,
this saved about 14 minutes (the single combined job took 54m, versus
44m plus 24m for ASan and UBSan jobs, respectively). That's wall-clock
and not CPU, but since our jobs are mostly CPU-bound, the two should be
closely proportional.
This does increase the end-to-end time of a CI run, though, since before
this patch the two jobs could run in parallel, and the sanitizer job is
our longest single job. It also means that we won't get a separate
result for "this passed with UBSan but not with ASan" or vice versa).
But as 1c0962c0c4 noted, that is not a very useful signal in practice.
Below are some more detailed timings of gcc vs clang that I measured by
running the test suite on my local workstation. Each measurement counts
only the time to run the test suite with each compiler (not the compile
time itself). We'll focus on the wall-clock times for simplicity, though
the CPU times follow roughly similar trends.
Here's a run with CC=gcc as a baseline:
real 1m12.931s
user 9m30.566s
sys 8m9.538s
Running with SANITIZE=address increases the time by a factor of ~4.7x:
real 5m40.352s
user 49m37.044s
sys 36m42.950s
Running with SANITIZE=undefined increases the time by a factor of ~1.7x:
real 2m5.956s
user 12m42.847s
sys 19m27.067s
So let's call that 6.4 time units to run them separately (where a unit
is the time it takes to run the test suite with no sanitizers). As a
simplistic model, we might imagine that running them together would take
5.4 units (we save 1 unit because we are no longer running the test
suite twice, but just paying the sanitizer overhead on top of a single
run).
But that's not what happens. Running with SANITIZE=address,undefined
results in a factor of 9.3x:
real 11m9.817s
user 77m31.284s
sys 96m40.454s
So not only did we not get faster when doing them together, we actually
spent 1.5x as much CPU as doing them separately! And while those
wall-clock numbers might not look too terrible, keep in mind that this
is on an unloaded 8-core machine. In the CI environment, wall-clock
times will be much closer to CPU times. So not only are we wasting CPU,
but we risk hitting timeouts.
Now let's try the same thing with clang. Here's our no-sanitizer
baseline run, which is almost identical to the gcc one (which is quite
convenient, because we can keep using the same "time units" to get an
apples-to-apples comparison):
real 1m11.844s
user 9m28.313s
sys 8m8.240s
And now again with SANITIZE=address, we get a 5x factor (so slightly
worse than gcc's 4.7x, though I wouldn't read too much into it; there is
a fair bit of run-to-run noise):
real 6m7.662s
user 49m24.330s
sys 44m13.846s
And with SANITIZE=undefined, we are at 1.5x, slightly outperforming gcc
(though again, that's probably mostly noise):
real 1m50.028s
user 11m0.973s
sys 16m42.731s
So running them separately, our total cost is 6.5x. But if we combine
them in a single run (SANITIZE=address,undefined), we get:
real 6m51.804s
user 52m32.049s
sys 51m46.711s
which is a factor of 5.7x. That's along the lines we'd hoped for!
Running them together saves us almost a whole time unit. And that's not
counting any time spent outside the test suite itself (starting the job,
setting up the environment, compiling) that we're no longer duplicating
by having two jobs.
So clang behaves like we'd hope: the overhead to run the sanitizers is
additive as you add more sanitizers. Whereas gcc's numbers seem very
close to multiplicative, almost as if the sanitizers were enforcing
their overheads on each other (though that is purely a guess on what is
going on; ultimately what matters to us is the amount of time it takes).
And that roughly matches the CI improvement I saw. A "time unit" there
is more like 12 minutes, and the observed time savings was 14 minutes
(with the extra presumably coming from avoiding duplicated setup, etc).

Both gcc and clang support the "address" and "undefined" sanitizers.
However, they may produce different results. We've seen at least two
real world cases where gcc missed a UBSan problem but clang found it:
1. Clang's UBSan (using clang 14.0.6) found a string index that was
subtracted to "-1", causing an out-of-bounds read (curiously this
didn't trigger ASan, but that may be because the string was in the
argv memory, not stack or heap). Using gcc (version 12.2.0) didn't
find the same problem.
Original thread:
https://lore.kernel.org/git/20230519005447.GA2955320@coredump.intra.peff.net/
2. Clang's UBSan (using clang 4.0.1) complained about pointer
arithmetic with NULL, but gcc at the time did not. This was in
2017, and modern gcc does seem to find the issue, though.
Original thread:
https://lore.kernel.org/git/32a8b949-638a-1784-7fba-948ae32206fc@web.de/
Since we don't otherwise have a particular preference for one compiler
over the other for this test, let's switch to the one that we think may
be more thorough.
Note that it's entirely possible that the two are simply _different_,
and we are trading off problems that gcc would find that clang wouldn't.
However, my subjective and anecdotal experience has been that clang's
sanitizer support is a bit more mature (e.g., I recall other oddities
around leak-checking where clang performed more sensibly).
Obviously running both and cross-checking the results would give us the
best coverage, but that's very expensive to run (and these are already
some of our most expensive CI jobs). So let's use clang as our best
guess, and we can re-evaluate if we get more data points.

The --follow code doesn't handle most forms of pathspec magic. We check
that no unexpected ones have made it to try_to_follow_renames() with a
runtime GUARD_PATHSPEC() check, which gives behavior like this:
$ git log --follow ':(icase)makefile' >/dev/null
BUG: tree-diff.c:596: unsupported magic 10
Aborted
The same is true of ":(glob)", ":(attr)", and so on. It's good that we
notice the problem rather than continuing and producing a wrong answer.
But there are two non-ideal things:
1. The idea of GUARD_PATHSPEC() is to catch programming errors where
low-level code gets unexpected pathspecs. We'd usually try to catch
unsupported pathspecs by passing a magic_mask to parse_pathspec(),
which would give the user a much better message like:
pathspec magic not supported by this command: 'icase'
That doesn't happen here because git-log usually _does_ support
all types of pathspec magic, and so it passes "0" for the mask
(this call actually happens in setup_revisions()). It needs to
distinguish the normal case from the "--follow" one but currently
doesn't.
2. In addition to --follow, we have the log.follow config option. When
that is set, we try to turn on --follow mode only when there is a
single pathspec (since --follow doesn't handle anything else). But
really, that ought to be expanded to "use --follow when the
pathspec supports it". Otherwise, we'd complain any time you use an
exotic pathspec:
$ git config log.follow true
$ git log ':(icase)makefile' >/dev/null
BUG: tree-diff.c:596: unsupported magic 10
Aborted
We should instead just avoid enabling follow mode if it's not
supported by this particular invocation.
This patch expands our diff_check_follow_pathspec() function to cover
pathspec magic, solving both problems.
A few final notes:
- we could also solve (1) by passing the appropriate mask to
parse_pathspec(). But that's not great for two reasons. One is that
the error message is less precise. It says "magic not supported by
this command", but really it is not the command, but rather the
--follow option which is the problem. The second is that it always
calls die(). But for our log.follow code, we want to speculatively
ask "is this pathspec OK?" and just get a boolean result.
- This is obviously the right thing to do for ':(icase)' and most
other magic options. But ':(glob)' is a bit odd here. The --follow
code doesn't support wildcards, but we allow them anyway. From
try_to_follow_renames():
#if 0
/*
* We should reject wildcards as well. Unfortunately we
* haven't got a reliable way to detect that 'foo\*bar' in
* fact has no wildcards. nowildcard_len is merely a hint for
* optimization. Let it slip for now until wildmatch is taught
* about dry-run mode and returns wildcard info.
*/
if (opt->pathspec.has_wildcard)
BUG("wildcards are not supported");
#endif
So something like "git log --follow 'Make*'" is already doing the
wrong thing, since ":(glob)" behavior is already the default (it is
used only to countermand an earlier --noglob-pathspecs).
So we _could_ loosen the guard to allow :(glob), since it just
behaves the same as pathspecs do by default. But it seems like a
backwards step to do so. It already doesn't work (it hits the BUG()
case currently), and given that the user took an explicit step to
say "this pathspec should glob", it is reasonable for us to say "no,
--follow does not support globbing" (or in the case of log.follow,
avoid turning on follow mode). Which is what happens after this
patch.
- The set of allowed pathspec magic is obviously the same as in
GUARD_PATHSPEC(). We could perhaps factor these out to avoid
repetition. The point of having separate masks and GUARD calls is
that we don't necessarily know which parsed pathspecs will be used
where. But in this case, the two are heavily correlated. Still,
there may be some value in keeping them separate; it would make
anyone think twice about adding new magic to the list in
diff_check_follow_pathspec(). They'd need to touch
try_to_follow_renames() as well, which is the code that would
actually need to be updated to handle more exotic pathspecs.
- The documentation for log.follow says that it enables --follow
"...when a single <path> is given". We could possibly expand that to
say "with no unsupported pathspec magic", but that raises the
question of documenting which magic is supported. I think the
existing wording of "single <path>" sufficiently encompasses the
idea (the forbidden magic is stuff that might match multiple
entries), and the spirit remains the same.

In --follow mode, we require exactly one pathspec. We check this
condition in two places:

inapropriate pathspec
- in git-log's revision "tweak" function, we enable log.follow only if
the pathspec allows it

decide at some point what to do about them, but that's a little lower
priority (as Git GUI seems to be unmaintained for the time being, and
the gitk maintainer keeps a very low profile on the Git mailing list,
too).

Git documentation refers to $HOME and $XDG_CONFIG_HOME often, but does not specify how or where these values come from on Windows where neither is set by default. The new documentation reflects the behavior of setup_windows_environment() in compat/mingw.c.

Git for Windows accepts pull requests; Core Git does not. Therefore we
need to adjust the template (because it only matches core Git's
project management style, not ours).
Also: direct Git for Windows enhancements to their contributions page,
space out the text for easy reading, and clarify that the mailing list
is plain text, not HTML.

Rather than using private IFTTT Applets that send mails to this
maintainer whenever a new version of a Git for Windows component was
released, let's use the power of GitHub workflows to make this process
publicly visible.
This workflow monitors the Atom/RSS feeds, and opens a ticket whenever a
new version was released.
Note: Bash sometimes releases multiple patched versions within a few
minutes of each other (i.e. 5.1p1 through 5.1p4, 5.0p15 and 5.0p16). The
MSYS2 runtime also has a similar system. We can address those patches as
a group, so we shouldn't get multiple issues about them.
Note further: We're not acting on newlib releases, OpenSSL alphas, Perl
release candidates or non-stable Perl releases. There's no need to open
issues about them.

Reintroduce the 'core.useBuiltinFSMonitor' config setting (originally added
in 0a756b2a25 (fsmonitor: config settings are repository-specific,
2021-03-05)) after its removal from the upstream version of FSMonitor.
Upstream, the 'core.useBuiltinFSMonitor' setting was rendered obsolete by
"overloading" the 'core.fsmonitor' setting to take a boolean value. However,
several applications (e.g., 'scalar') utilize the original config setting,
so it should be preserved for a deprecation period before complete removal:
* if 'core.fsmonitor' is a boolean, the user is correctly using the new
config syntax; do not use 'core.useBuiltinFSMonitor'.
* if 'core.fsmonitor' is unspecified, use 'core.useBuiltinFSMonitor'.
* if 'core.fsmonitor' is a path, override and use the builtin FSMonitor if
'core.useBuiltinFSMonitor' is 'true'; otherwise, use the FSMonitor hook
indicated by the path.
Additionally, for this deprecation period, advise users to switch to using
'core.fsmonitor' to specify their use of the builtin FSMonitor.

The `--stdin` option was a well-established paradigm in other commands,
therefore we implemented it in `git reset` for use by Visual Studio.
Unfortunately, upstream Git decided that it is time to introduce
`--pathspec-from-file` instead.
To keep backwards-compatibility for some grace period, we therefore
reinstate the `--stdin` option on top of the `--pathspec-from-file`
option, but mark it firmly as deprecated.

Getting started contributing to Git can be difficult on a Windows
machine. CONTRIBUTING.md contains a guide to getting started, including
detailed steps for setting up build tools, running tests, and
submitting patches to upstream.

The Git project followed suite and added their Code of Conduct, based on
the Contributors' Covenant v1.4.
We edit it slightly to reflect Git for Windows' particulars.

The Git for Windows project has grown quite complex over the years,
certainly much more complex than during the first years where the
`msysgit.git` repository was abusing Git for package management purposes
and the `git/git` fork was called `4msysgit.git`.
Let's describe the status quo in a thorough way.
