We check if the "mode" argument supplied by the user is valid by seeing
if we have a mode_$mode function defined. But we don't do that until
after creating the tempfile. This is wasteful (we create a tempfile but
never use it), and makes it harder to add new options (the recent stdout
option exits before creating the tempfile, so it misses the check and
"git jump --stdout foo" will produce "git-jump: 92: mode_foo: not found"
rather than the regular usage message).

"make coccicheck" is time consuming. It has been made to run more
incrementally.

Makefile: don't create a ".build/.build/" for cocci, fix output
spatchcache: add a ccache-alike for "spatch"
cocci: run against a generated ALL.cocci
cocci rules: remove <id>'s from rules that don't need them

cocci: make "coccicheck" rule incremental
cocci: split off "--all-includes" from SPATCH_FLAGS

Makefile + shared.mak: rename and indent $(QUIET_SPATCH_T)
Apply "index-compatibility.pending.cocci" rule to "builtin/*", but
exclude those where we conflict with in-flight changes.
As a result some of them end up using only "the_index", so let's have
them use the more narrow "USE_THE_INDEX_VARIABLE" rather than
"USE_THE_INDEX_COMPATIBILITY_MACROS".
Manual changes not made by coccinelle, that were squashed in:
* Whitespace-wrap argument lists for repo_hold_locked_index(),
repo_read_index_preload() and repo_refresh_and_write_index(), in cases
where the line became too long after the transformation.
* Change "refresh_cache()" to "refresh_index()" in a comment in
"builtin/update-index.c".
* For those whose call was followed by perror("<macro-name>"), change
it to perror("<function-name>"), referring to the new function.

Mostly apply the part of "index-compatibility.pending.cocci" that
renames the global variables like "active_nr", which are a shorthand
to referencing (in that case) a struct member as "the_index.cache_nr".
In doing so move more of "index-compatibility.pending.cocci" to
"index-compatibility.cocci".
In the case of "active_nr" we'd have a textual conflict with
"ab/various-leak-fixes" in "next"[1]. Let's exclude that specific case
while moving the rule over from "pending".

As in preceding commits the only manual changes here are the macro

Since 4aab5b46f4 (Make read-cache.c "the_index" free., 2007-04-01)
we've been undergoing a slow migration away from these macros, but
haven't made much progress since f8adbec9fe (cache.h: flip

Let's move forward a bit by changing the users of those macros that
are rare enough that we can convert them in one go, and then remove
the compatibility shim.
The only manual change to the C code here is to "cache.h", the rest is

Address the root cause of technical debt we've been carrying since
sha1collisiondetection was made the default in [1]. In a preceding
commit we narrowly fixed a bug where the "DC_SHA1" variable would be
unset (in combination with "NO_APPLE_COMMON_CRYPTO=" on OSX), even
though we had the sha1collisiondetection library enabled.
But the only reason we needed to have such a user-exposed knob went
away with [1], and it's been doing nothing useful since then. We don't
care if you define DC_SHA1=*, we only care that you don't ask for any
other SHA-1 implementation. If it turns out that you didn't, we'll use
sha1collisiondetection, whether you had "DC_SHA1" set or not.
As a result of this being confusing we had e.g. [2] for cmake and the
recent [3] for ci/lib.sh setting "DC_SHA1" explicitly, even though
this was always a NOOP.
A much simpler way to do this is to stop having the Makefile and
CMakeLists.txt set "DC_SHA1" to be picked up by the test-lib.sh, let's
instead add a trivial "test-tool sha1-is-sha1dc". It returns zero if
we're using sha1collisiondetection, non-zero otherwise.

Add a rather trivial "spatchcache", with this running e.g.:
make cocciclean
make contrib/coccinelle/free.cocci.patch \
SPATCH=contrib/coccicheck/spatchcache \
SPATCH_FLAGS=--very-quiet
Is cut down from ~20s to ~5s on my system. Much of that is either
fixable shell overhead, or the around 40 files we "CANTCACHE" (see the
implementation).
This uses "redis" as a cache by default, but it's configurable. See
the embedded documentation.
This is *not* like ccache in that we won't cache failed spatch
invocations, or those where spatch suggests changes for us. Those
cases are so rare that I didn't think it was worth the bother, by far
the most common case is that it has no suggested changes. We'll also
refuse to cache any "spatch" invocation that has output on stderr,
which means that "--very-quiet" must be added to "SPATCH_FLAGS".
Because we narrow the cache to that we don't need to save away stdout,
stderr & the exit code. We simply cache the cases where we had no
suggested changes.
Another benchmark is to compare this with the previous
SPATCH_BATCH_SIZE=N, as noted in [1]. Before this (on my 8 core system) running:
make clean; time make contrib/coccinelle/array.cocci.patch SPATCH_BATCH_SIZE=0
Would take 33s, but with the preceding changes running without this
"spatchcache" is slightly slower, or around 35s:
make clean; time make contrib/coccinelle/array.cocci.patch
Now doing the same with SPATCH=contrib/coccinelle/spatchcache will
take around 6s, but we'll need to compile the *.o files first to take
full advantage of it (which can be fast with "ccache"):
make clean; make; time make contrib/coccinelle/array.cocci.patch SPATCH=contrib/coccinelle/spatchcache

The preceding commits to make the "coccicheck" target incremental made
it slower in some cases. As an optimization let's not have the
many=many mapping of <*.cocci>=<*.[ch]>, but instead concat the
<*.cocci> into an ALL.cocci, and then run one-to-many
ALL.cocci=<*.[ch]>.
A "make coccicheck" is now around 2x as fast as it was on "master",
and around 1.5x as fast as the preceding change to make the run
incremental:
$ git hyperfine -L rev origin/master,HEAD~,HEAD -p 'make clean' 'make coccicheck SPATCH=spatch COCCI_SOURCES="$(echo $(ls o*.c builtin/h*.c))"' -r 3

1.97 ± 0.05 times faster than 'make coccicheck SPATCH=spatch COCCI_SOURCES="$(echo $(ls o*.c builtin/h*.c))"' in 'HEAD~'
This can be turned off with SPATCH_CONCAT_COCCI, but as the
beneficiaries of "SPATCH_CONCAT_COCCI=" would mainly be those
developing the *.cocci rules themselves, let's leave this optimization
on by default.
For more information see my "Optimizing *.cocci rules by concat'ing
them" (<220901.8635dbjfko.gmgdl@evledraar.gmail.com>) on the
cocci@inria.fr mailing list.
This potentially changes the results of our *.cocci rules, but as
noted in that discussion it should be safe for our use. We don't name
rules, or if we do their names don't conflict across our *.cocci
files.
To the extent that we'd have any inter-dependencies between rules this
doesn't make that worse, as we'd have them now if we ran "make
coccicheck", applied the results, and would then have (due to
hypothetical interdependencies) suggested changes on the subsequent
"make coccicheck".
Our "coccicheck-test" target makes use of the ALL.cocci when running
tests, e.g. when testing unused.{c,out} we test it against ALL.cocci,
not unused.cocci. We thus assert (to the extent that we have test
coverage) that this concatenation doesn't change the expected results
of running these rules.

The <id> in the <rulename> part of the coccinelle syntax[1] is for our
purposes there to declares if we have inter-dependencies between
different rules.
But such <id>'s must be unique within a given semantic patch file. As
we'll be processing a concatenated version of our rules in the
subsequent commit let's remove these names. They weren't being used
for the semantic patches themselves, and equated to a short comment
about the rule.
Both the filename and context of the rules makes it clear what they're
doing, so we're not gaining anything from keeping these. Retaining
them goes against recommendations that "contrib/coccinelle/README"
will be making in the subsequent commit.
This leaves only one named rule in our sources, where it's needed for
a "<id> <-> <extends> <id>" relationship:

Improve the incremental rebuilding support of "coccicheck" by
piggy-backing on the computed dependency information of the
corresponding *.o file, rather than rebuilding all <RULE>/<FILE> pairs
if either their corresponding file changes, or if any header changes.
This in effect uses the same method that the "sparse" target was made
to use in c234e8a0ec (Makefile: make the "sparse" target non-.PHONY,
2021-09-23), except that the dependency on the *.o file isn't a hard
one, we check with $(wildcard) if the *.o file exists, and if so we'll
depend on it.
This means that the common case of:
make
make coccicheck
Will benefit from incremental rebuilding, now changing e.g. a header
will only re-run "spatch" on those those *.c files that make use of
it:
By depending on the *.o we piggy-back on
COMPUTE_HEADER_DEPENDENCIES. See c234e8a0ec (Makefile: make the
"sparse" target non-.PHONY, 2021-09-23) for prior art of doing that
for the *.sp files. E.g.:
make contrib/coccinelle/free.cocci.patch
make -W column.h contrib/coccinelle/free.cocci.patch
Will take around 15 seconds for the second command on my 8 core box if
I didn't run "make" beforehand to create the *.o files. But around 2
seconds if I did and we have those "*.o" files.
Notes about the approach of piggy-backing on *.o for dependencies:
* It *is* a trade-off since we'll pay the extra cost of running the C
compiler, but we're probably doing that anyway. The compiler is much
faster than "spatch", so even though we need to re-compile the *.o to
create the dependency info for the *.c for "spatch" it's
faster (especially if using "ccache").
* There *are* use-cases where some would like to have *.o files
around, but to have the "make coccicheck" ignore them. See:
https://lore.kernel.org/git/20220826104312.GJ1735@szeder.dev/
For those users a:
make
make coccicheck SPATCH_USE_O_DEPENDENCIES=
Will avoid considering the *.o files.
* If that *.o file doesn't exist we'll depend on an intermediate file
of ours which in turn depends on $(FOUND_H_SOURCES).
This covers both an initial build, or where "coccicheck" is run
without running "all" beforehand, and because we run "coccicheck"
on e.g. files in compat/* that we don't know how to build unless
the requisite flag was provided to the Makefile.
Most of the runtime of "incremental" runs is now spent on various
compat/* files, i.e. we conditionally add files to COMPAT_OBJS, and
therefore conflate whether we *can* compile an object and generate
dependency information for it with whether we'd like to link it
into our binary.
Before this change the distinction didn't matter, but now one way
to make this even faster on incremental builds would be to peel
those concerns apart so that we can see that e.g. compat/mmap.c
doesn't depend on column.h.

Optimize the very slow "coccicheck" target to take advantage of
incremental rebuilding, and fix outstanding dependency problems with
the existing rule.
The rule is now faster both on the initial run as we can make better
use of GNU make's parallelism than the old ad-hoc combination of
make's parallelism combined with $(SPATCH_BATCH_SIZE) and/or the
"--jobs" argument to "spatch(1)".
It also makes us *much* faster when incrementally building, it's now
viable to "make coccicheck" as topic branches are merged down.
The rule didn't use FORCE (or its equivalents) before, so a:
make coccicheck
make coccicheck
Would report nothing to do on the second iteration. But all of our
patch output depended on all $(COCCI_SOURCES) files, therefore e.g.:
make -W grep.c coccicheck
Would do a full re-run, i.e. a a change in a single file would force
us to do a full re-run.
The reason for this (not the initial rationale, but my analysis) is:
* Since we create a single "*.cocci.patch+" we don't know where to
pick up where we left off, or how to incrementally merge e.g. a
"grep.c" change with an existing *.cocci.patch.
* We've been carrying forward the dependency on the *.c files since
63f0a758a0 (add coccicheck make target, 2016-09-15) the rule was
initially added as a sort of poor man's dependency discovery.
As we don't include other *.c files depending on other *.c files
has always been broken, as could be trivially demonstrated
e.g. with:
make coccicheck
make -W strbuf.h coccicheck
However, depending on the corresponding *.c files has been doing
something, namely that *if* an API change modified both *.c and *.h
files we'd catch the change to the *.h we care about via the *.c
being changed.
For API changes that happened only via *.h files we'd do the wrong
thing before this change, but e.g. for function additions (not
"static inline" ones) catch the *.h change by proxy.
Now we'll instead:
* Create a <RULE>/<FILE> pair in the .build directory, E.g. for
swap.cocci and grep.c we'll create
.build/contrib/coccinelle/swap.cocci.patch/grep.c.
That file is the diff we'll apply for that <RULE>-<FILE>
combination, if there's no changes to me made (the common case)
it'll be an empty file.
* Our generated *.patch
file (e.g. contrib/coccinelle/swap.cocci.patch) is now a simple "cat
$^" of all of all of the <RULE>/<FILE> files for a given <RULE>.
In the case discussed above of "grep.c" being changed we'll do the
full "cat" every time, so they resulting *.cocci.patch will always
be correct and up-to-date, even if it's "incrementally updated".
See 1cc0425a27 (Makefile: have "make pot" not "reset --hard",
2022-05-26) for another recent rule that used that technique.
As before we'll:
* End up generating a contrib/coccinelle/swap.cocci.patch, if we
"fail" by creating a non-empty patch we'll still exit with a zero
exit code.
Arguably we should move to a more Makefile-native way of doing
this, i.e. fail early, and if we want all of the "failed" changes
we can use "make -k", but as the current
"ci/run-static-analysis.sh" expects us to behave this way let's
keep the existing behavior of exhaustively discovering all cocci
changes, and only failing if spatch itself errors out.
Further implementation details & notes:
* Before this change running "make coccicheck" would by default end
up pegging just one CPU at the very end for a while, usually as
we'd finish whichever *.cocci rule was the most expensive.
This could be mitigated by combining "make -jN" with
SPATCH_BATCH_SIZE, see 960154b9c1 (coccicheck: optionally batch
spatch invocations, 2019-05-06).
There will be cases where getting rid of "SPATCH_BATCH_SIZE" makes
things worse, but a from-scratch "make coccicheck" with the default
of SPATCH_BATCH_SIZE=1 (and tweaking it doesn't make a difference)
is faster (~3m36s v.s. ~3m56s) with this approach, as we can feed
the CPU more work in a less staggered way.
* Getting rid of "SPATCH_BATCH_SIZE" particularly helps in cases
where the default of 1 yields parallelism under "make coccicheck",
but then running e.g.:
make -W contrib/coccinelle/swap.cocci coccicheck
I.e. before that would use only one CPU core, until the user
remembered to adjust "SPATCH_BATCH_SIZE" differently than the
setting that makes sense when doing a non-incremental run of "make
coccicheck".
* Before the "make coccicheck" rule would have to clean
"contrib/coccinelle/*.cocci.patch*", since we'd create "*+" and
"*.log" files there. Now those are created in
.build/contrib/coccinelle/, which is covered by the "cocciclean" rule
already.
Outstanding issues & future work:
* We could get rid of "--all-includes" in favor of manually
specifying a list of includes to give to "spatch(1)".
As noted upthread of [1] a naïve removal of "--all-includes" will
result in broken *.cocci patches, but if we know the exhaustive
list of includes via COMPUTE_HEADER_DEPENDENCIES we don't need to
re-scan for them, we could grab the headers to include from the
.depend.d/<file>.o.d and supply them with the "--include" option to
spatch(1).q

The previous commit fixed a failure in 'git subtree merge --squash' when
the previous squash-merge merged an annotated tag of the subtree
repository which is missing locally.
The same failure happens in 'git subtree split', either directly or when
called by 'git subtree push', under the same circumstances: 'cmd_split'
invokes 'find_existing_splits', which loops through previous commits and
invokes 'git rev-parse' (via 'process_subtree_split_trailer') on the
value of any 'git subtree-split' trailer it finds. This fails if this
value is the hash of an annotated tag which is missing locally.
Add a new optional argument 'repository' to 'cmd_split' and
'find_existing_splits', and invoke 'cmd_split' with that argument from
'cmd_push'. This allows 'process_subtree_split_trailer' to try to fetch
the missing tag from the 'repository' if it's not available locally,
mirroring the new behaviour of 'git subtree pull' and 'git subtree
merge'.

When 'git subtree merge --squash $ref' is invoked, either directly or
through 'git subtree pull --squash $repo $ref', the code looks for the
latest squash merge of the subtree in order to create the new merge
commit as a child of the previous squash merge.
This search is done in function 'process_subtree_split_trailer', invoked
by 'find_latest_squash', which looks for the most recent commit with a
'git-subtree-split' trailer; that trailer's value is the object name in
the subtree repository of the ref that was last squash-merged. The
function verifies that this object is present locally with 'git
rev-parse', and aborts if it's not.
The hash referenced by the 'git-subtree-split' trailer is guaranteed to
correspond to a commit since it is the result of running 'git rev-parse
-q --verify "$1^{commit}"' on the first argument of 'cmd_merge' (this
corresponds to 'rev' in 'cmd_merge' which is passed through to
'new_squash_commit' and 'squash_msg').
But this is only the case since e4f8baa88a (subtree: parse revs in
individual cmd_ functions, 2021-04-27), which went into Git 2.32. Before
that commit, 'cmd_merge' verified the revision it was given using 'git
rev-parse --revs-only "$@"'. Such an invocation, when fed the name of an
annotated tag, would return the hash of the tag, not of the commit
referenced by the tag.
This leads to a failure in 'find_latest_squash' when squash-merging if
the most recent squash-merge merged an annotated tag of the subtree
repository, using a pre-2.32 version of 'git subtree', unless that
previous annotated tag is present locally (which is not usually the
case).
We can fix this by fetching the object directly by its hash in
'process_subtree_split_trailer' when 'git rev-parse' fails, but in order
to do so we need to know the name or URL of the subtree repository.
This is not possible in general for 'git subtree merge', but is easy
when it is invoked through 'git subtree pull' since in that case the
subtree repository is passed by the user at the command line.
Allow the 'git subtree pull' scenario to work out-of-the-box by adding
an optional 'repository' argument to functions 'cmd_merge',
'find_latest_squash' and 'process_subtree_split_trailer', and invoke
'cmd_merge' with that 'repository' argument in 'cmd_pull'.
If 'repository' is absent in 'process_subtree_split_trailer', instruct
the user to try fetching the missing object directly.

The processing done for the 'git-subtree-split' trailer is simple: we
check if the object exists with 'rev-parse' and set the variable
'sub' to the object name, or we die if the object does not exist.
In a future commit we will add more steps to the processing of this
trailer in order to make the code more robust.
To reduce code duplication, move the processing of the
'git-subtree-split' trailer to a dedicated function,
'process_subtree_split_trailer'.

The function 'find_latest_squash' takes a single argument, 'dir', but a
debug statement uses this variable before it takes its value from $1.
This statement thus gets the value of 'dir' from the calling function,
which currently is the same as the 'dir' argument, so it works but it
is confusing.
Move the definition of 'dir' before its first use.

There are three occurences of 'git rev-parse <rev>' in 'git-subtree.sh'
where the command expects a revision and the script dies or exits if the
revision can't be found. In that case, the error message from 'git
rev-parse' is:
$ git rev-parse <bad rev>
<bad rev>
fatal: ambiguous argument '<bad rev>': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
This is a little confusing to the user, since this error message is
outputed by 'git subtree'.
At these points in the script, we know that we are looking for a single
revision, so be explicit by using '--verify', resulting in a little
better error message:
$ git rev-parse --verify <bad rev>
fatal: Needed a single revision
In the two occurences where we 'die' if 'git rev-parse' fails, 'git
subtree' outputs "could not rev-parse split hash $b from commit $sq", so
we actually do not need the supplementary error message from 'git
rev-parse'; add '--quiet' to silence it.
In the third occurence, we 'exit', so keep the error message from 'git
rev-parse'. Note that this messsage is still suboptimal since it can be
understood to mean that 'git rev-parse' did not receive a single
revision as argument, which is not the case here: the command did
receive a single revision, but the revision is not resolvable to an
available object.
The alternative would be to use '--' after the revision, as suggested by
the first error message, resulting in a clearer error message:
$ git rev-parse <bad rev> --
fatal: bad revision '<bad rev>'
Unfortunately we can't use that syntax because in the more common case
of the revision resolving to a known object, the command outputs the
object's hash, a newline, and the dashdash, which breaks the 'git
subtree' script.

As suggested in
https://github.com/git-for-windows/git/issues/3966#issuecomment-1221264238,
t7112 can run for well over one hour, which seems to be the default
maximum run time at least when running CTest-based tests in Visual
Studio.
Let's increase the time-out as a stop gap to unblock developers wishing
to run Git's test suite in Visual Studio.
Note: The actual run time is highly dependent on the circumstances. For
example, in Git's CI runs, the Windows-based tests typically take a bit
over 5 minutes to run. CI runs have the added benefit that Windows
Defender (the common anti-malware scanner on Windows) is turned off,
something many developers are not at liberty to do on their work
stations. When Defender is turned on, even on this developer's high-end
Ryzen system, t7112 takes over 15 minutes to run.

In 7f5397a07c (cmake: support for testing git when building out of the
source tree, 2020-06-26), we implemented support for running Git's test
scripts even after building Git in a different directory than the source
directory.
The way we did this was to edit the file `t/test-lib.sh` to override
`GIT_BUILD_DIR` to point somewhere else than the parent of the `t/`
directory.
This is unideal because it always leaves a tracked file marked as
modified, and it is all too easy to commit that change by mistake.
Let's change the strategy by teaching `t/test-lib.sh` to detect the
presence of a file called `GIT-BUILD-DIR` in the source directory. If it
exists, the contents are interpreted as the location to the _actual_
build directory. We then write this file as part of the CTest
definition.
To support building Git via a regular `make` invocation after building
it using CMake, we ensure that the `GIT-BUILD-DIR` file is deleted (for
convenience, this is done as part of the Makefile rule that is already
run with every `make` invocation to ensure that `GIT-BUILD-OPTIONS` is
up to date).

When a test script fails in Git's test suite, the usual course of action
is to re-run it using options to increase the verbosity of the output,
e.g. `-v` and `-x`.
Like in Git's CI runs, when running the tests in Visual Studio via the
CTest route, it is cumbersome or at least requires a very unintuitive
approach to pass options to the test scripts: the CMakeLists.txt file
would have to be modified, passing the desired options to _all_ test
scripts, and then the CMake Cache would have to be reconfigured before
running the test in question individually. Unintuitive at best, and
opposite to the niceties IDE users expect.
So let's just pass those options by default: This will not clutter any
output window but the log that is written to a log file will have
information necessary to figure out test failures.
While at it, also imitate what the Windows jobs in Git's CI runs do to
accelerate running the test scripts: pass the `--no-bin-wrappers` and
`--no-chain-lint` options.
This makes the test runs noticeably faster because the `bin-wrappers/`
scripts as well as the `chain-lint` code make heavy use of POSIX shell
scripting, which is really, really slow on Windows due to the need to
emulate POSIX behavior via the MSYS2 runtime. In a test by Eric
Sunshine, it added two minutes (!) just to perform the chain-lint task.
The idea of adding a CMake config option (á la `GIT_TEST_OPTS`) was
considered during the development of this patch, but then dropped: such
a setting is global, across _all_ tests, where e.g. `--run=...` would
not make sense. Users wishing to override these new defaults are better
advised running the test script manually, in a Git Bash, with full
control over the command line.

Move 'scalar' out of 'contrib/' and into the root of the Git tree. The goal
of this change is to build 'scalar' as part of the standard Git build &

This patch includes both the physical move of Scalar's files out of
'contrib/' ('scalar.c', 'scalar.txt', and 't9xxx-scalar.sh'), and the
changes to the build definitions in 'Makefile' and 'CMakelists.txt' to
accommodate the new program.

- there is a 'scalar-objs' target (similar to those created in 029bac01a8
(Makefile: add {program,xdiff,test,git,fuzz}-objs & objects targets,
2021-02-23)) for debugging purposes.
- it appears in the root of the install directory (rather than the
gitexecdir).
- it is included in the 'bin-wrappers/' directory for use in tests.
- it receives a platform-specific executable suffix (e.g., '.exe'), if
applicable.
- 'scalar.txt' is installed as 'man1' documentation.
- the 'clean' target removes the 'scalar' executable.
Additionally, update the root level '.gitignore' file to ignore the Scalar
executable.

By automatically invoking chainlint.sed upon each test it runs,
`test_run_` in test-lib.sh ensures that broken &&-chains will be
detected early as tests are modified or new are tests created since it
is typical to run a test script manually (i.e. `./t1234-test-script.sh`)
during test development. Now that the implementation of chainlint.pl is
complete, modify test-lib.sh to invoke it automatically instead of
chainlint.sed each time a test script is run.
This change reduces the number of "linter" invocations from 26800+ (once
per test run) down to 1050+ (once per test script), however, a
subsequent change will drop the number of invocations to 1 per `make
test`, thus fully realizing the benefit of the new linter.
Note that the "magic exit code 117" &&-chain checker added by bb79af9d09
(t/test-lib: introduce --chain-lint option, 2015-03-20) which is built
into t/test-lib.sh is retained since it has near zero-cost and
(theoretically) may catch a broken &&-chain not caught by chainlint.pl.

Make the search for repository and enlistment root in
'setup_enlistment_directory()' more constrained to simplify behavior and
adhere to 'GIT_CEILING_DIRECTORIES'.
Previously, 'setup_enlistment_directory()' would check whether the provided
path (or current working directory) '<dir>' or its subdirectory '<dir>/src'
was a repository root. If not, the process would repeat on the parent of
'<dir>' until the repository was found or it reached the root of the
filesystem. This meant that a user could specify a path *anywhere* inside an
enlistment (including paths not in the repository contained within the
enlistment) and it would be found.
The downside to this process is that the search would not account for
'GIT_CEILING_DIRECTORIES', so the upward search could result in modifying
repository contents past 'GIT_CEILING_DIRECTORIES'. Similarly, operations
like 'scalar delete' could end up unintentionally deleting the parent of a
repo if its root was named 'src'.
To make this 'setup_enlistment_directory()' both adhere to
'GIT_CEILING_DIRECTORIES' and avoid unwanted deletions, the search for an
enlistment directory is simplified to:
- if '<dir>/src' is a repository root, '<dir>' is the enlistment root
- if '<dir>' is either the repository root or contained within a repository,
the repository root is the enlistment root
Now, only 'setup_git_directory()' (called by 'setup_enlistment_directory()')
searches upwards from the 'scalar' specified path, enforcing
'GIT_CEILING_DIRECTORIES' in the process. Additionally, 'scalar delete
<dir>/src' will not delete '<dir>' (if users would like to delete it, they
can still specify the enlistment root with 'scalar delete <dir>'). This is
true of any 'scalar' operation; users can invoke 'scalar' on the enlistment
root, but paths must otherwise be inside the repository to be valid.
To help clarify the updated behavior, new tests are added to
't9099-scalar.sh'.
Finally, this change leaves 'strbuf_parent_directory()' with only a single,
WIN32-specific caller in 'delete_enlistment()'. Rather than wrap
'strbuf_parent_directory()' in '#ifdef WIN32' to avoid the "unused function"
compiler error, move the contents of 'strbuf_parent_directory()' into
'delete_enlistment()' and remove the function.

Update 'create_diagnostics_archive()' to take an argument 'mode'. When
archiving diagnostics for a repository, 'mode' is used to selectively
include/exclude information based on its value. The initial options for
'mode' are:
* DIAGNOSE_NONE: do not collect any diagnostics or create an archive
(no-op).
* DIAGNOSE_STATS: collect basic repository metadata (Git version, repo path,
filesystem available space) as well as sizing and count statistics for the
repository's objects and packfiles.
* DIAGNOSE_ALL: collect basic repository metadata, sizing/count statistics,
and copies of the '.git', '.git/hooks', '.git/info', '.git/logs', and
'.git/objects/info' directories.
These modes are introduced to provide users the option to collect
diagnostics without the sensitive information included in copies of '.git'
dir contents. At the moment, only 'scalar diagnose' uses
'create_diagnostics_archive()' (with a hardcoded 'DIAGNOSE_ALL' mode to
match existing functionality), but more callers will be introduced in
subsequent patches.
Finally, refactor from a hardcoded set of 'add_directory_to_archiver()'
calls to iterative invocations gated by 'DIAGNOSE_ALL'. This allows for
easier future modification of the set of directories to archive and improves
error reporting when 'add_directory_to_archiver()' fails.

Remove the "test_external" function added in [1]. This arguably makes
the output of t9700-perl-git.sh and friends worse. But as we'll argue
below the trade-off is worth it, since "chaining" to another TAP
emitter in test-lib.sh is more trouble than it's worth.
The new output of t9700-perl-git.sh is now:
$ ./t9700-perl-git.sh
ok 1 - set up test repository
ok 2 - use t9700/test.pl to test Git.pm
# passed all 2 test(s)
1..2
Whereas before this change it would be:
$ ./t9700-perl-git.sh
ok 1 - set up test repository
# run 1: Perl API (perl /home/avar/g/git/t/t9700/test.pl)
ok 2 - use Git;
[... omitting tests 3..46 from t/t9700/test.pl ...]
ok 47 - unquote escape sequences
1..47
# test_external test Perl API was ok
# test_external_without_stderr test no stderr: Perl API was ok
At the time of its addition supporting "test_external" was easy, but
when test-lib.sh itself started to emit TAP in [2] we needed to make
everything surrounding the emission of the plan consider
"test_external". I added that support in [2] so that we could run:
prove ./t9700-perl-git.sh :: -v
But since then in [3] the door has been closed on combining
$HARNESS_ACTIVE and -v, we'll now just die:
$ prove ./t9700-perl-git.sh :: -v
Bailout called. Further testing stopped: verbose mode forbidden under TAP harness; try --verbose-log
FAILED--Further testing stopped: verbose mode forbidden under TAP harness; try --verbose-log
So the only use of this has been that *if* we had failure in one of
these tests we could e.g. in CI see which test failed based on the
test number. Now we'll need to look at the full verbose logs to get
that same information.
I think this trade-off is acceptable given the reduction in
complexity, and it brings these tests in line with other similar
tests, e.g. the reftable tests added in [4] will be condensed down to
just one test, which invokes the C helper:
$ ./t0032-reftable-unittest.sh
ok 1 - unittests
# passed all 1 test(s)
1..1
It would still be nice to have that ":: -v" form work again, it
never *really* worked, but even though we've had edge cases test
output screwing up the TAP it mostly worked between d998bd4ab6 and
[3], so we may have been overzealous in forbidding it outright.
I have local patches which I'm planning to submit sooner than later
that get us to that goal, and in a way that isn't buggy. In the
meantime getting rid of this special case makes hacking on this area
of test-lib.sh easier, as we'll do in subsequent commits.
The switch from "perl" to "$PERL_PATH" here is because "perl" is
defined as a shell function in the test suite, see a5bf824f3b (t:

2018-02-25). On e.g. the OSX CI the "command perl"... will be part of

When "make test" is run with the default of "DEFAULT_TEST_TARGET=test"
we'll leave the "test-results" directory in-place, but don't do so for
the "prove" target.
The reason for this is that when 28d836c815 (test: allow running the
tests under "prove", 2010-10-14) allowed for running the tests under
"prove" there was no point in leaving the "test-results" in place.
The "prove" target provides its own summary, so we don't need to run
"aggregate-results", which is the reason we have "test-results" in the
first place. See 2d84e9fb6d (Modify test-lib.sh to output stats to
t/test-results/*, 2008-06-08).
But in a subsequent commit test-lib.sh will start emitting reports of
memory leaks in test-results/*, and it will be useful to analyze these
after the fact.
This wouldn't be a problem as failing tests will halt the removal of
the files (we'll never reach "clean-except-prove-cache" from the
"prove" target), but will be subsequently as we'll want to report a
successful run, but might still have e.g. logs of known memory leaks
in test-results/*.
So let's stop removing this, it's sufficient that "make clean" removes
it, and that "pre-clean" (which both "test" and "prove" depend on)
will remove it, i.e. we'll never have a stale "test-results" because
of this change.

Generalize the newly added "unused.cocci" rule to find more than just
"struct strbuf", let's have it find the same unused patterns for
"struct string_list", as well as other code that uses
similar-looking *_{release,clear,free}() and {release,clear,free}_*()
functions.
We're intentionally loose in accepting e.g. a "strbuf_init(&sb)"
followed by a "string_list_clear(&sb, 0)". It's assumed that the
compiler will catch any such invalid code, i.e. that our
constructors/destructors don't take a "void *".
See [1] for example of code that would be covered by the
"get_worktrees()" part of this rule. We'd still need work that the
series is based on (we were passing "worktrees" to a function), but
could now do the change in [1] automatically.

Add a coccinelle rule to remove "struct strbuf" initialization
followed by calling "strbuf_release()" function, without any uses of
the strbuf in the same function.
See the tests in contrib/coccinelle/tests/unused.{c,res} for what it's
intended to find and replace.
The inclusion of "contrib/scalar/scalar.c" is because "spatch" was
manually run on it (we don't usually run spatch on contrib).
Per the "buggy code" comment we also match a strbuf_init() before the
xmalloc(), but we're not seeking to be so strict as to make checks
that the compiler will catch for us redundant. Saying we'll match
either "init" or "xmalloc" lines makes the rule simpler.

Add a "coccicheck-test" target to test our *.cocci rules, and as a
demonstration add tests for the rules added in 39ea59a257 (remove
unnecessary NULL check before free(3), 2016-10-08) and
1b83d1251e (coccinelle: add a rule to make "expression" code use
FREE_AND_NULL(), 2017-06-15).
I considered making use of the "spatch --test" option, and the choice
of a "tests" over a "t" directory is to make these tests compatible
with such a future change.
Unfortunately "spatch --test" doesn't return meaningful exit codes,
AFAICT you need to "grep" its output to see if the *.res is what you
expect. There's "--test-okfailed", but I didn't find a way to sensibly
integrate those (it relies on some in-between status files, but
doesn't help with the status codes).
Instead let's use a "--sp-file" pattern similar to the main
"coccicheck" rule, with the difference that we use and compare the
two *.res files with cmp(1).
The --very-quiet and --no-show-diff options ensure that we don't need
to pipe stdout and stderr somewhere. Unlike the "%.cocci.patch" rule
we're not using the diff.
The "cmp || git diff" is optimistically giving us better output on
failure, but even if we only have POSIX cmp and no system git
installed we'll still fail with the "cmp", just with an error message
that isn't as friendly. The "2>/dev/null" is in case we don't have a
"git" installed.

stop using the GIT_QUIET variable there were only four uses in
git-subtree.sh. Let's have it use an "arg_quiet" variable instead, and
move the "say" function over to it.
The only other use was a trivial message in git-instaweb.sh, since it
has never supported the --quiet option (or similar) that code added in
0b624b4cee (instaweb: restart server if already running, 2009-11-22)
can simply use "echo" instead.

The contrib/vscode/init.sh script initializes the .vscode directory with
some helpful metadata so VS Code handles Git code better.
One big issue that VS Code has is detecting the tab width based on file
type. ".txt" files were not covered by this script before, so add them
with the appropriate tab widths. This prevents inserting spaces instead
of tabs and keeps the tab width to eight instead of four or two.
While we are here, remove the "editor.wordWrap" settings. The editor's
word wrap is only cosmetic: it does not actually insert newlines when
your typing goes over the column limit. This can make it appear like you
have properly wrapped code, but it is incorrect. Further, existing code
that is over the column limit is wrapped even if your editor window is
wider than the limit. This can make reading such code more difficult.
Without these lines, VS Code renders the lines accurately, without
"ghost" newlines.

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.

Over the course of Scalar's development, it became obvious that there is
a need for a command that can gather all kinds of useful information
that can help identify the most typical problems with large
worktrees/repositories.
The `diagnose` command is the culmination of this hard-won knowledge: it
gathers the installed hooks, the config, a couple statistics describing
the data shape, among other pieces of information, and then wraps
everything up in a tidy, neat `.zip` archive.
Note: originally, Scalar was implemented in C# using the .NET API, where
we had the luxury of a comprehensive standard library that includes
basic functionality such as writing a `.zip` file. In the C version, we
lack such a commodity. Rather than introducing a dependency on, say,
libzip, we slightly abuse Git's `archive` machinery: we write out a
`.zip` of the empty try, augmented by a couple files that are added via
the `--add-file*` options. We are careful trying not to modify the
current repository in any way lest the very circumstances that required
`scalar diagnose` to be run are changed by the `diagnose` run itself.

The `scalar` command needs a Scalar enlistment for many subcommands, and
looks in the current directory for such an enlistment (traversing the
parent directories until it finds one).
These is subcommands can also be called with an optional argument
specifying the enlistment. Here, too, we traverse parent directories as
needed, until we find an enlistment.
However, if the specified directory does not even exist, or is not a
directory, we should stop right there, with an error message.

Create another thread to watch over the daemon process and
automatically shut it down if necessary.
This commit creates the basic framework for a "health" thread
to monitor the daemon and/or the file system. Later commits
will add platform-specific code to do the actual work.
The "health" thread is intended to monitor conditions that
would be difficult to track inside the IPC thread pool and/or
the file system listener threads. For example, when there are
file system events outside of the watched worktree root or if
we want to have an idle-timeout auto-shutdown feature.
This commit creates the health thread itself, defines the thread-proc
and sets up the thread's event loop. It integrates this new thread
into the existing IPC and Listener thread models.
This commit defines the API to the platform-specific code where all of
the monitoring will actually happen.
The platform-specific code for MacOS is just stubs. Meaning that the
health thread will immediately exit on MacOS, but that is OK and
expected. Future work can define MacOS-specific monitoring.
The platform-specific code for Windows sets up enough of the
WaitForMultipleObjects() machinery to watch for system and/or custom
events. Currently, the set of wait handles only includes our custom
shutdown event (sent from our other theads). Later commits in this
series will extend the set of wait handles to monitor other
conditions.

13092a91 (cocci: refactor common patterns to use xstrdup_or_null(),
2016-10-12) introduced a rule to rewrite this conditional call to
xstrdup(E) and an assignment to variable V:
- if (E)
- V = xstrdup(E);
into an unconditional call to xstrdup_or_null(E) and an assignment
to variable V:
+ V = xstrdup_or_null(E);
which is utterly bogus. The original code may already have an
acceptable value in V and the conditional assignment may be to
improve the value already in V with a copy of a better value E when
(and only when) E is not NULL.
The rewritten construct unconditionally discards the existing value
of V and replaces it with a copy of E, even when E is NULL, which
changes the meaning of the program.
By the way, if it were
-if (E && !V)
- V = xstrdup(E);
+V = xstrdup_or_null(E);
it would probably have been correct. But there is no existing code
that would have been improved by such a rule, so let's just remove
the bogus one without replacing with the more specific one.

Remove the 'reset.quiet' config option, remove '--no-quiet' documentation in
'Documentation/git-reset.txt'. In 4c3abd0551 (reset: add new reset.quiet
config setting, 2018-10-23), 'reset.quiet' was introduced as a way to
globally change the default behavior of 'git reset --mixed' to skip index
refresh.
However, now that '--quiet' does not affect index refresh, 'reset.quiet'
would only serve to globally silence logging. This was not the original
intention of the config setting, and there's no precedent for such a setting
in other commands with a '--quiet' option, so it appears to be obsolete.
In addition to the options & its documentation, remove 'reset.quiet' from

If a file has been staged, we don't want to list it, as restoring those

Makefiles: add "shared.mak", move ".DELETE_ON_ERROR" to it
scalar Makefile: use "The default target of..." pattern
This commit introduces the `core.fsyncMethod` configuration
knob, which can currently be set to `fsync` or `writeout-only`.
The new writeout-only mode attempts to tell the operating system to
flush its in-memory page cache to the storage hardware without issuing a
CACHE_FLUSH command to the storage controller.
Writeout-only fsync is significantly faster than a vanilla fsync on
common hardware, since data is written to a disk-side cache rather than
all the way to a durable medium. Later changes in this patch series will
take advantage of this primitive to implement batching of hardware
flushes.
When git_fsync is called with FSYNC_WRITEOUT_ONLY, it may fail and the
caller is expected to do an ordinary fsync as needed.
On Apple platforms, the fsync system call does not issue a CACHE_FLUSH
directive to the storage controller. This change updates fsync to do
fcntl(F_FULLFSYNC) to make fsync actually durable. We maintain parity
with existing behavior on Apple platforms by setting the default value
of the new core.fsyncMethod option.

need to export the "QUIET_GEN" and "QUIET_BUILT_IN" variables
anymore. The "QUIET_GEN" variable is used in "git-gui/Makefile" and

We have various behavior that's shared across our Makefiles, or that
really should be (e.g. via defined templates). Let's create a
top-level "shared.mak" to house those sorts of things, and start by
adding the ".DELETE_ON_ERROR" flag to it.
See my own 7b76d6bf22 (Makefile: add and use the ".DELETE_ON_ERROR"
flag, 2021-06-29) and db10fc6c09 (doc: simplify Makefile using
.DELETE_ON_ERROR, 2021-05-21) for the addition and use of the
".DELETE_ON_ERROR" flag.
I.e. this changes the behavior of existing rules in the altered
Makefiles (except "Makefile" & "Documentation/Makefile"). I'm
confident that this is safe having read the relevant rules in those
Makfiles, and as the GNU make manual notes that it isn't the default
behavior is out of an abundance of backwards compatibility
caution. From edition 0.75 of its manual, covering GNU make 4.3:
[Enabling '.DELETE_ON_ERROR' is] almost always what you want
'make' to do, but it is not historical practice; so for
compatibility, you must explicitly request it.
This doesn't introduce a bug by e.g. having this
".DELETE_ON_ERROR" flag only apply to this new shared.mak, Makefiles
have no such scoping semantics.
It does increase the danger that any Makefile without an explicit "The
default target of this Makefile is..." snippet to define the default
target as "all" could have its default rule changed if our new
shared.mak ever defines a "real" rule. In subsequent commits we'll be
careful not to do that, and such breakage would be obvious e.g. in the
case of "make -C t".
We might want to make that less fragile still (e.g. by using
".DEFAULT_GOAL" as noted in the preceding commit), but for now let's
simply include "shared.mak" without adding that boilerplate to all the
Makefiles that don't have it already. Most of those are already
exposed to that potential caveat e.g. due to including "config.mak*".

The script uses "git show -s" to display the title of the merge
commit being studied, without explicitly disabling the pager, which
is not a safe thing to do in a script.
For example, when the pager is set to "less" with "-SF" options (-S
tells the pager not to fold lines but allow horizontal scrolling to
show the overly long lines, -F tells the pager not to wait if the
output in its entirety is shown on a single page), and the title of
the merge commit is longer than the width of the terminal, the pager
will wait until the end-user tells it to quit after showing the
single line.
Explicitly disable the pager with this "git show" invocation to fix
this.
The command uses the "--pretty=format:..." format, which adds LF in
between each pair of commits it outputs, which means that the label
for the merge being learned from will be followed by the next
message on the same line. "--pretty=tformat:..." is what we should
instead, which adds LF after each commit, or a more modern way to
spell it, i.e. "--format=...". This existing breakage becomes
easier to see, now we no longer use the pager.

to re-use the logic in __git_index_files, this method removed
subdirectories (e.g. folder1/0/ became folder1/), so instead new custom
logic was placed directly in the __gitcomp_directories method.
Note there are two tests for this new functionality - one for spaces and
accents and one for backslashes and tabs. The backslashes and tabs test
uses FUNNYNAMES to avoid running on Windows. This is because:
1. Backslashes are explicitly not allowed in Windows file paths.
2. Although tabs appear to be allowed when creating a file in a Windows
bash shell, they actually are not renderable (and appear as empty boxes
in the shell).

Use new __gitcomp_directories method to complete directory names in cone
mode sparse-checkouts. This method addresses the caveat of poor
performance in monorepos from the previous commit (by completing only one
level of directories).
The unusual character caveat from the previous commit will be fixed by the
final commit in this series.

Correct multiple issues with tab completion of the git sparse-checkout
command. These issues were:
1. git sparse-checkout <TAB> previously resulted in an incomplete list of
subcommands (it was missing reapply and add).
2. Subcommand options were not tab-completable.
3. git sparse-checkout set <TAB> and git sparse-checkout add <TAB> showed
both file names and directory names. While this may be a less surprising
behavior for non-cone mode, cone mode sparse checkouts should complete
only directory names.
Note that while the new strategy of just using git ls-tree to complete on
directory names is simple and a step in the right direction, it does have
some caveats. These are:
1. Likelihood of poor performance in large monorepos (as a result of
recursively completing directory names).
2. Inability to handle paths containing unusual characters.
These caveats will be fixed by subsequent commits in this series.

The `git` executable has these two very useful options:
-C <directory>:
switch to the specified directory before performing any actions
-c <key>=<value>:
temporarily configure this setting for the duration of the
specified scalar subcommand
With this commit, we teach the `scalar` executable the same trick.
Note: It might look like a good idea to try to reuse the
`handle_options()` function in `git.c` instead of replicating only the
`-c`/`-C` part. However, that function is not only not in `libgit.a`, it
is also intricately entangled with the rest of the code in `git.c` that
is necessary e.g. to handle `--paginate`. Besides, no other option
handled by that `handle_options()` function is relevant to Scalar,
therefore the cost of refactoring vastly would outweigh the benefit.

There are many situations in which having access to a cryptographically
secure pseudorandom number generator (CSPRNG) is helpful. In the
future, we'll encounter one of these when dealing with temporary files.
To make this possible, let's add a function which reads from a system
CSPRNG and returns some bytes.
We know that all systems will have such an interface. A CSPRNG is
required for a secure TLS or SSH implementation and a Git implementation
which provided neither would be of little practical use. In addition,
POSIX is set to standardize getentropy(2) in the next version, so in the
(potentially distant) future we can rely on that.
For systems which lack one of the other interfaces, we provide the
ability to use OpenSSL's CSPRNG. OpenSSL is highly portable and
functions on practically every known OS, and we know it will have access
to some source of cryptographically secure randomness. We also provide
support for the arc4random in libbsd for folks who would prefer to use
that.
Because this is a security sensitive interface, we take some
precautions. We either succeed by filling the buffer completely as we
requested, or we fail. We don't return partial data because the caller
will almost never find that to be a useful behavior.
Specify a makefile knob which users can use to specify one or more
suitable CSPRNGs, and turn the multiple string options into a set of
defines, since we cannot match on strings in the preprocessor. We allow
multiple options to make the job of handling this in autoconf easier.
The order of options is important here. On systems with arc4random,
which is most of the BSDs, we use that, since, except on MirBSD and
macOS, it uses ChaCha20, which is extremely fast, and sits entirely in
userspace, avoiding a system call. We then prefer getrandom over
getentropy, because the former has been available longer on Linux, and
then OpenSSL. Finally, if none of those are available, we use
/dev/urandom, because most Unix-like operating systems provide that API.
We prefer options that don't involve device files when possible because
those work in some restricted environments where device files may not be
available.
Set the configuration variables appropriately for Linux and the BSDs,
including macOS, as well as Windows and NonStop. We specifically only
consider versions which receive publicly available security support
here. For the same reason, we don't specify getrandom(2) on Linux,
because CentOS 7 doesn't support it in glibc (although its kernel does)
and we don't want to resort to making syscalls.
Finally, add a test helper to allow this to be tested by hand and in
tests. We don't add any tests, since invoking the CSPRNG is not likely
to produce interesting, reproducible results.

Failures within `for` and `while` loops can go unnoticed if not detected
and signaled manually since the loop itself does not abort when a
contained command fails, nor will a failure necessarily be detected when
the loop finishes since the loop returns the exit code of the last
command it ran on the final iteration, which may not be the command
which failed. Therefore, detect and signal failures manually within
loops using the idiom `|| return 1` (or `|| exit 1` within subshells).

The .NET version of Scalar has a `version` command. This was necessary
because it was versioned independently of Git.
Since Scalar is now tightly coupled with Git, it does not make sense for
them to show different versions. Therefore, it shows the same output as
`git version`. For backwards-compatibility with the .NET version,
`scalar version` prints to `stderr`, though (`git version` prints to
`stdout` instead).

This implements Scalar's opinionated `clone` command: it tries to use a
partial clone and sets up a sparse checkout by default. In contrast to
`git clone`, `scalar clone` sets up the worktree in the `src/`
subdirectory, to encourage a separation between the source files and the
build output (which helps Git tremendously because it avoids untracked
files that have to be specifically ignored when refreshing the index).
Also, it registers the repository for regular, scheduled maintenance,
and configures a flurry of configuration settings based on the
experience and experiments of the Microsoft Windows and the Microsoft
Office development teams.
Note: since the `scalar clone` command is by far the most commonly
called `scalar` subcommand, we document it at the top of the manual

To test the Scalar command, create a test script in contrib/scalar/t

Note: This test script is intended to test `scalar` only lightly, even

A more comprehensive functional (or: integration) test suite can be

The idea of Scalar (https://github.com/microsoft/scalar), and before
that, of VFS for Git, has always been to prove that Git _can_ scale, and
to upstream whatever strategies have been demonstrated to help.
With this patch, we start the journey from that C# project to move what
is left to Git's own `contrib/` directory, reimplementing it in pure C,
with the intention to facilitate integrating the functionality into core
Git all while maintaining backwards-compatibility for existing Scalar
users (which will be much easier when both live in the same worktree).
It has always been the plan to contribute all of the proven strategies
back to core Git.
For example, while the virtual filesystem provided by VFS for Git helped
the team developing the Windows operating system to move onto Git, while
trying to upstream it we realized that it cannot be done: getting the
virtual filesystem to work (which we only managed to implement fully on
Windows, but not on, say, macOS or Linux), and the required server-side
support for the GVFS protocol, made this not quite feasible.
The Scalar project learned from that and tackled the problem with
different tactics: instead of pretending to Git that the working
directory is fully populated, it _specifically_ teaches Git about
partial clone (which is based on VFS for Git's cache server), about
sparse checkout (which VFS for Git tried to do transparently, in the
file system layer), and regularly runs maintenance tasks to keep the
repository in a healthy state.
With partial clone, sparse checkout and `git maintenance` having been
upstreamed, there is little left that `scalar.exe` does which `git.exe`
cannot do. One such thing is that `scalar clone <url>` will
automatically set up a partial, sparse clone, and configure
known-helpful settings from the start.
So let's bring this convenience into Git's tree.
The idea here is that you can (optionally) build Scalar via
make -C contrib/scalar/
This will build the `scalar` executable and put it into the
contrib/scalar/ subdirectory.
The slightly awkward addition of the `contrib/scalar/*` bits to the
top-level `Makefile` are actually really required: we want to link to
`libgit.a`, which means that we will need to use the very same `CFLAGS`
and `LDFLAGS` as the rest of Git.
An early development version of this patch tried to replicate all the
conditional code in `contrib/scalar/Makefile` (e.g. `NO_POLL`) just like
`contrib/svn-fe/Makefile` used to do before it was retired. It turned
out to be quite the whack-a-mole game: the SHA-1-related flags, the
flags enabling/disabling `compat/poll/`, `compat/regex/`,
`compat/win32mmap.c` & friends depending on the current platform... To
put it mildly: it was a major mess.
Instead, this patch makes minimal changes to the top-level `Makefile` so
that the bits in `contrib/scalar/` can be compiled and linked, and
adds a `contrib/scalar/Makefile` that uses the top-level `Makefile` in a
most minimal way to do the actual compiling.
Note: With this commit, we only establish the infrastructure, no
Scalar functionality is implemented yet; We will do that incrementally
over the next few commits.

The C99 standard was released in January 1999, now 22 years ago. It
provides a variety of useful features, including variadic arguments for
macros, declarations after statements, designated initializers, and a
wide variety of other useful features, many of which we already use.
We'd like to take advantage of these features, but we want to be
cautious. As far as we know, all major compilers now support C99 or a
later C standard, such as C11 or C17. POSIX has required C99 support as
a requirement for the 2001 revision, so we can safely assume any POSIX
system which we are interested in supporting has C99.
Even MSVC, long a holdout against modern C, now supports both C11 and
C17 with an appropriate update. Moreover, even if people are using an
older version of MSVC on these systems, they will generally need some
implementation of the standard Unix utilities for the testsuite, and GNU
coreutils, the most common option, has required C99 since 2009.
Therefore, we can safely assume that a suitable version of GCC or clang
is available to users even if their version of MSVC is not sufficiently
capable.
Let's add a test balloon to git-compat-util.h to see if anyone is using
an older compiler. We'll add a comment telling people how to enable
this functionality on GCC and Clang, even though modern versions of both
will automatically do the right thing, and ask people still experiencing
a problem to report that to us on the list.
Note that C89 compilers don't provide the __STDC_VERSION__ macro, so we
use a well-known hack of using "- 0". On compilers with this macro, it
doesn't change the value, and on C89 compilers, the macro will be
replaced with nothing, and our value will be 0.
For sparse, we explicitly request the gnu99 style because we've
traditionally taken advantage of some GCC- and clang-specific extensions
when available and we'd like to retain the ability to do that. sparse
also defaults to C89 without it, so things will fail for us if we don't.
Update the cmake configuration to require C11 for MSVC. We do this
because this will make MSVC to use C11, since it does not explicitly
support C99. We do this with a compiler options because setting the
C_STANDARD option does not work in our CI on MSVC and at the moment, we
don't want to require C11 for Unix compilers.
In the Makefile, don't set any compiler flags for the compiler itself,
since on some systems, such as FreeBSD, we actually need C11, and asking
for C99 causes things to fail to compile. The error message should make
it obvious what's going wrong and allow a user to set the appropriate
option when building in the event they're using a Unix compiler that
doesn't support it by default.

"zdiff3" is identical to ordinary diff3 except that it allows compaction
of common lines on the two sides of history at the beginning or end of
the conflict hunk. For example, the following diff3 conflict:

would instead get the following conflict:

2

4
A
<<<<<<
B
C
D
||||||
5
6
======
X

Y
>>>>>>
E
7
8
9
Note that the common lines, 'A', and 'E' were moved outside the
conflict. Unlike with the two-way conflicts from the 'merge'
conflictStyle, the zdiff3 conflict is NOT split into multiple conflict
regions to allow the common 'C' lines to be shown outside a conflict,
because zdiff3 shows the base version too and the base version cannot be
reasonably split.
Note also that the removing of lines common to the two sides might make
the remaining text inside the conflict region match the base text inside
the conflict region (for example, if the diff3 conflict had '5 6 E' on
the right side of the conflict, then the common line 'E' would be moved
outside and both the base and right side's remaining conflict text would
be the lines '5' and '6'). This has the potential to surprise users and
make them think there should not have been a conflict, but there
definitely was a conflict and it should remain.

In the basic `[`/`test` command, the string equality operator is a
single `=`. The `==` operator is only available in `[[`, which is a
bash-ism also supported by zsh.
This mix-up was causing the following completion error in zsh:
> __git_ls_files_helper:7: = not found
(That message refers to the extraneous symbol in `==` ← `=`).
This updates that comparison to use a single `=` inside the
basic `[ … ]` test conditional.
Although this fix is inconsistent with the other comparisons in this
file, which use `[[ … == … ]]`, and the two expressions are functionally
identical in this context, that approach was rejected due to a
preference for `[`.

Introduce a "uniq" subroutine, otherwise --cc-cover, --to-cover and

Remove the sane_grep() shell function in git-sh-setup. The two reasons
for why it existed don't apply anymore:
1. It was added due to GNU grep supporting GREP_OPTIONS. See
e1622bfcba (Protect scripted Porcelains from GREP_OPTIONS insanity,
2009-11-23).
Newer versions of GNU grep ignore that, but even on older versions
its existence won't matter, none of these sane_grep() uses care
about grep's output, they're merely using it to check if a string
exists in a file or stream. We also don't care about the "LC_ALL=C"
that "sane_grep" was using, these greps for fixed or ASCII strings
will behave the same under any locale.
2. The SANE_TEXT_GREP added in 71b401032b (sane_grep: pass "-a" if
grep accepts it, 2016-03-08) isn't needed either, none of these grep
uses deal with binary data.

In C it isn't required to specify that all members of a struct are
zero'd out to 0, NULL or '\0', just providing a "{ 0 }" will
accomplish that.
Let's also change code that provided N zero'd fields to just
provide one, and change e.g. "{ NULL }" to "{ 0 }" for
consistency. I.e. even if the first member is a pointer let's use "0"
instead of "NULL". The point of using "0" consistently is to pick one,
and to not have the reader wonder why we're not using the same pattern
everywhere.

In the last few commits we focused on code in unpack-trees.c that
mistakenly removed untracked files or directories. There may be more of
those, but in this commit we change our focus: callers of toplevel
commands that are expected to remove untracked files or directories.
As noted previously, we have toplevel commands that are expected to
delete untracked files such as 'read-tree --reset', 'reset --hard', and
'checkout --force'. However, that does not mean that other highlevel
commands that happen to call these other commands thought about or
conveyed to users the possibility that untracked files could be removed.
Audit the code for such callsites, and add comments near existing
callsites to mention whether these are safe or not.
My auditing is somewhat incomplete, though; it skipped several cases:
* git-rebase--preserve-merges.sh: is in the process of being
deprecated/removed, so I won't leave a note that there are
likely more bugs in that script.
* contrib/git-new-workdir: why is the -f flag being used in a new
empty directory?? It shouldn't hurt, but it seems useless.
* git-p4.py: Don't see why -f is needed for a new dir (maybe it's
not and is just superfluous), but I'm not at all familiar with
the p4 stuff
* git-archimport.perl: Don't care; arch is long since dead
* git-cvs*.perl: Don't care; cvs is long since dead
Also, the reset --hard in builtin/worktree.c looks safe, due to only
running in an empty directory.

Make githooks(5) the source of truth for what hooks git supports, and
punt out early on hooks we don't know about in find_hook(). This
ensures that the documentation and the C code's idea about existing
hooks doesn't diverge.
We still have Perl and Python code running its own hooks, but that'll
be addressed by Emily Shaffer's upcoming "git hook run" command.
This resolves a long-standing TODO item in bugreport.c of there being
no centralized listing of hooks, and fixes a bug with the bugreport
listing only knowing about 1/4 of the p4 hooks. It didn't know about
the recent "reference-transaction" hook either.
We could make the find_hook() function die() or BUG() out if the new
known_hook() returned 0, but let's make it return NULL just as it does
when it can't find a hook of a known type. Making it die() is overly
anal, and unlikely to be what we need in catching stupid typos in the
name of some new hook hardcoded in git.git's sources. By making this
be tolerant of unknown hook names, changes in a later series to make
"git hook run" run arbitrary user-configured hook names will be easier
to implement.
I have not been able to directly test the CMake change being made
here. Since 4c2c38e800 (ci: modification of main.yml to use cmake for
vs-build job, 2020-06-26) some of the Windows CI has a hard dependency
on CMake, this change works there, and is to my eyes an obviously
correct use of a pattern established in previous CMake changes,
namely:
- 061c2240b1 (Introduce CMake support for configuring Git,
2020-06-12)
- 709df95b78 (help: move list_config_help to builtin/help,
2020-04-16)
- 976aaedca0 (msvc: add a Makefile target to pre-generate the Visual
Studio solution, 2019-07-29)
The LC_ALL=C is needed because at least in my locale the dash ("-") is
ignored for the purposes of sorting, which results in a different
order. I'm not aware of anything in git that has a hard dependency on
the order, but e.g. the bugreport output would end up using whatever
locale was in effect when git was compiled.

The "help" builtin has been able to emit configuration variables since
e17ca92637 (completion: drop the hard coded list of config vars,
2018-05-26), but it hasn't produced exactly the format the completion
script wanted. Let's do that.
We got partway there in 2675ea1cc0 (completion: use 'sort -u' to
deduplicate config variable names, 2019-08-13) and
d9438873c4 (completion: deduplicate configuration sections,
2019-08-13), but after both we still needed some sorting,
de-duplicating and awk post-processing of the list.
We can instead simply do the relevant parsing ourselves (we were doing
most of it already), and call string_list_remove_duplicates() after
already sorting the list, so the caller doesn't need to invoke "sort
-u". The "--config-for-completion" output is the same as before after
being passed through "sort -u".
Then add a new "--config-sections-for-completion" option. Under that
output we'll emit config sections like "alias" (instead of "alias." in
the --config-for-completion output).
We need to be careful to leave the "--config-for-completion" option
compatible with users git, but are still running a shell with an older
git-completion.bash. If we e.g. changed the option name they'd see
messages about git-completion.bash being unable to find the
"--config-for-completion" option.
Such backwards compatibility isn't something we should bend over
backwards for, it's only helping users who:
* Upgrade git
* Are in an old shell
* The git-completion.bash in that shell hasn't cached the old
"--config-for-completion" output already.
But since it's easy in this case to retain compatibility, let's do it,
the older versions of git-completion.bash won't care that the input
they get doesn't change after a "sort -u".
While we're at it let's make "--config-for-completion" die if there's
anything left over in "argc", and do the same in the new
"--config-sections-for-completion" option.

This fix only works for versions of bash greater than 4.0, before that

In 22d5507493 (subtree: don't fuss with PATH, 2021-04-27), `git
subtree` was broken thoroughly on Windows.
The reason is that it assumes Unix semantics, where `PATH` is
colon-separated, and it assumes that `$GIT_EXEC_PATH:` is a verbatim
prefix of `$PATH`. Neither are true, the latter in particular because
`GIT_EXEC_PATH` is a Windows-style path, while `PATH` is a Unix-style
path list.
Let's make extra certain that `$GIT_EXEC_PATH` and the first component
of `$PATH` refer to different entities before erroring out.
We do that by using the `test <path1> -ef <path2>` command that verifies
that the inode of `<path1>` and of `<path2>` is the same.
Sadly, this construct is non-portable, according to
https://pubs.opengroup.org/onlinepubs/009695399/utilities/test.html.
However, it does not matter in practice because we still first look
whether `$GIT_EXEC_PREFIX` is string-identical to the first component of
`$PATH`. This will give us the expected result everywhere but in Git for
Windows, and Git for Windows' own Bash _does_ handle the `-ef` operator.
Just in case that we _do_ need to show the error message _and_ are
running in a shell that lacks support for `-ef`, we simply suppress the
error output for that part.

Some users have expressed interest in a more "batteries included" way of
building via CMake[1], and a big part of that is providing easier access
to tooling external tools.
A straightforward way to accomplish this is to make it as simple as
possible is to enable the generation of the compile_commands.json file,
which is supported by many tools such as: clang-tidy, clang-format,
sourcetrail, etc.
This does come with a small run-time overhead during the configuration
step (~6 seconds on my machine):
Time to configure with CMAKE_EXPORT_COMPILE_COMMANDS=TRUE
real 1m9.840s
user 0m0.031s
sys 0m0.031s
Time to configure with CMAKE_EXPORT_COMPILE_COMMANDS=FALSE
real 1m3.195s
user 0m0.015s
sys 0m0.015s
This seems like a small enough price to pay to make the project more
accessible to newer users. Additionally there are other large projects
like llvm [2] which has had this enabled by default for >6 years at the
time of this writing, and no real negative consequences that I can find
with my search-skills.
NOTE: That the compile_commands.json is currently produced only when
using the Ninja and Makefile generators. See The CMake documentation[3]
for more info.

When building on windows users have the option to use vcpkg to provide
the dependencies needed to compile. Previously, this was used only when
using the Visual Studio generator which was not ideal because:
- Not all users who want to use vcpkg use the Visual Studio
generators.
- Some versions of Visual Studio 2019 moved away from using the
VS 2019 generator by default, making it impossible for Visual
Studio to configure the project in the likely event that it couldn't
find the dependencies.
- Inexperienced users of CMake are very likely to get tripped up by
the errors caused by a lack of vcpkg, making the above bullet point
both annoying and hard to debug.
As such, let's make using vcpkg the default on windows. Users who want
to avoid using vcpkg can disable it by passing -DNO_VCPKG=TRUE.

Portability fix for command line completion script (in contrib/).
* si/zsh-complete-comment-fix:
work around zsh comment in __git_complete_worktree_paths
Further update the command line completion (in contrib/) for "git
stash".
* dl/complete-stash-updates:
git-completion.bash: consolidate cases in _git_stash()
git-completion.bash: use $__git_cmd_idx in more places
git-completion.bash: rename to $__git_cmd_idx
git-completion.bash: separate some commands onto their own line
The command line completion (in contrib/) for "git stash" has been
updated.
* dl/complete-stash:
git-completion.bash: use __gitcomp_builtin() in _git_stash()
git-completion.bash: extract from else in _git_stash()
git-completion.bash: pass $__git_subcommand_idx from __git_main()
[PATCH]: contrib/completion/git-completion.bash, there is a construct
where comment lines are placed between the command that is on
the upstream of a pipe and the command that is on the downstream
of a pipe in __git_complete_worktree_paths function.
Unfortunately, this script is also used by Zsh completion, but
Zsh mishandles this construct when "interactive_comments" option is not
set (by default it is off on macOS), resulting in a breakage:
$ git worktree remove [TAB]
$ git worktree remove __git_complete_worktree_paths:7: command not found: #
Move the comment, even though it explains what happens on the
downstream of the pipe and logically belongs where it is right
now, before the entire pipeline, to work around this problem.

completion: avoid aliased command lookup error in nounset mode
Don't silently ignore a flag that's invalid for a given subcommand. The
user expected it to do something; we should tell the user that they are
mistaken, instead of surprising the user.
It could be argued that this change might break existing users. I'd
argue that those existing users are already broken, and they just don't
know it. Let them know that they're broken.

'git subtree split' lets you specify a rev other than HEAD. 'git push'
lets you specify a mapping between a local thing and a remot ref. So
smash those together, and have 'git subtree push' let you specify which
local thing to run split on and push the result of that split to the
remote ref.

'push' does a 'split' internally, but it doesn't pass flags through to the
'split'. This is silly, if you need to pass flags to 'split', then it
means that you can't use 'push'!
So, have 'push' accept 'split' flags, and pass them through to 'split'.
Add tests for this by copying split's tests with minimal modification.

Besides being a genuinely useful thing to do, this also just makes sense
and harmonizes which flags may be used when. `git subtree split
--rejoin` amounts to "automatically go ahead and do a `git subtree
merge` after doing the main `git subtree split`", so it's weird and
arbitrary that you can't pass `--squash` to `git subtree split --rejoin`
like you can `git subtree merge`. It's weird that `git subtree split
--rejoin` inherits `git subtree merge`'s `--message` but not `--squash`.
Reconcile the situation by just having `split --rejoin` actually just
call `merge` internally (or call `add` instead, as appropriate), so it
can get access to the full `merge` behavior, including `--squash`.

Just went through the docs looking for anything inaccurate or that can
be improved.
In the '-h' text, in the man page synopsis, and in the man page
description: Normalize the ordering of the list of sub-commands: 'add',
'merge', 'split', 'pull', 'push'. This allows us to kinda separate the
lower-level add/merge/split from the higher-level pull/push.
'-h' text:
- correction: Indicate that split's arg is optional.
- clarity: Emphasize that 'pull' takes the 'add'/'merge' flags.
man page:
- correction: State that all subcommands take options (it seemed to
indicate that only 'split' takes any options other than '-P').
- correction: 'split' only guarantees that the results are identical if
the flags are identical.
- correction: The flag is named '--ignore-joins', not '--ignore-join'.
- completeness: Clarify that 'push' always operates on HEAD, and that
'split' operates on HEAD if no local commit is given.
- clarity: In the description, when listing commands, repeat what their
arguments are. This way the reader doesn't need to flip back and
forth between the command description and the synopsis and the full
description to understand what's being said.
- clarity: In the <variables> used to give command arguments, give
slightly longer, descriptive names. Like <local-commit> instead of
just <commit>.
- clarity: Emphasize that 'pull' takes the 'add'/'merge' flags.
- style: In the synopsis, list options before the subcommand. This
makes things line up and be much more readable when shown
non-monospace (such as in `make html`), and also more closely matches
other man pages (like `git-submodule.txt`).
- style: Use the correct syntax for indicating the options ([<options>]
instead of [OPTIONS]).
- style: In the synopsis, separate 'pull' and 'push' from the other
lower-level commands. I think this helps readability.
- style: Code-quote things in prose that seem like they should be
code-quoted, like '.gitmodules', flags, or full commands.
- style: Minor wording improvements, like more consistent mood (many
of the command descriptions start in the imperative mood and switch
to the indicative mode by the end). That sort of thing.
- style: Capitalize "ID".
- style: Remove the "This option is only valid for XXX command" remarks
from each option, and instead rely on the section headings.
- style: Since that line is getting edited anyway, switch "behaviour" to
American "behavior".
- style: Trim trailing whitespace.
`todo`:

Currently, the $indent variable is just used to track how deeply we're
nested, and the debug log is indented by things like
debug " foo"
That is: The indentation-level is hard-coded. It used to be that the
code couldn't recurse, so the indentation level could be known
statically, so it made sense to just hard-code it in the
output. However, since 315a84f9aa ("subtree: use commits before rejoins
for splits", 2018-09-28), it can now recurse, and the debug log is
misleading.
So fix that. Indent according to $indent.

Currently, debug output (triggered by passing '-d') and progress output
stomp on each other. The debug output is just streamed as lines to
stderr, and the progress output is sent to stderr as '%s\r'. When
writing to a file, it is awkward to read and difficult to distinguish
between the debug output and a progress line. When writing to a
terminal the debug lines hide progress lines.
So, when '-d' has been passed, spit out progress as 'progress: %s\n',
instead of as '%s\r', so that it can be detected, and so that the debug
lines don't overwrite the progress when written to a terminal.

For each function in subtree, add a usage comment saying what the
arguments are, and add an `assert` checking the number of arguments.
In figuring out each thing's arguments in order to write those comments
and assertions, it turns out that find_existing_splits is written as if
it takes multiple 'revs', but it is in fact only ever passed a single
'rev':
unrevs="$(find_existing_splits "$dir" "$rev")" || exit $?
So go ahead and codify that by documenting and asserting that it takes
exactly two arguments, one dir and one rev.

The main argument parser goes ahead and tries to parse revs to make
things simpler for the sub-command implementations. But, it includes
enough special cases for different sub-commands. And it's difficult
having having to think about "is this info coming from an argument, or a
global variable?". So the main argument parser's effort to make things
"simpler" ends up just making it more confusing and complicated.
Begone with the 'revs' global variable; parse 'rev=$(...)' as needed in
individual 'cmd_*' functions.
Begone with the 'default' global variable. Its would-be value is
knowable just from which function we're in.
Begone with the 'ensure_single_rev' function. Its functionality can be
achieved by passing '--verify' to 'git rev-parse'.
