The 't/test-results' directory and its contents are by-products of the
test process, so 'make clean' should remove them, but, alas, this has
been broken since fee65b194d (t/Makefile: don't remove test-results in
"clean-except-prove-cache", 2022-07-28).
The 'clean' target in 't/Makefile' was not directly responsible for
removing the 'test-results' directory, but relied on its dependency
'clean-except-prove-cache' to do that [1]. ee65b194d broke this,
because it only removed the 'rm -r test-results' command from the
'clean-except-prove-cache' target instead of moving it to the 'clean'
target, resulting in stray 't/test-results' directories.
Add that missing cleanup command to 't/Makefile', and to all
sub-Makefiles touched by that commit as well.

Hoist the remainder of "scalar" out of contrib/ to the main part of
the codebase.
* vd/scalar-to-main:
Documentation/technical: include Scalar technical doc
t/perf: add 'GIT_PERF_USE_SCALAR' run option
t/perf: add Scalar performance tests
scalar-clone: add test coverage
scalar: add to 'git help -a' command list
scalar: implement the `help` subcommand
git help: special-case `scalar`
scalar: include in standard Git build & installation
scalar: fix command documentation section header
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 &
install processes.
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.
At a high level, Scalar is built so that:
- 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.

Rename the last section header in 'contrib/scalar/scalar.txt' from "Scalar"
to "GIT". The linting rules of the 'documentation' CI build enforce the
existence of a "GIT" section in command documentation. Although 'scalar.txt'
is not yet checked, it will be in a future patch.
Here, changing the header name is more appropriate than making a
Scalar-specific exception to the linting rule. The existing "Scalar" section
contains only a link back to the main Git documentation, essentially the
same as the "GIT" section in builtin documentation. Changing the section
name further clarifies the Scalar-Git association and maintains consistency
with the rest of Git.

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.

Replace implementation of 'scalar diagnose' with an internal invocation of
'git diagnose --mode=all'. This simplifies the implementation of
'cmd_diagnose' by making it a direct alias of 'git diagnose' and removes
some code in 'scalar.c' that is duplicated in 'builtin/diagnose.c'. The
simplicity of the alias also sets up a clean deprecation path for 'scalar
diagnose' (in favor of 'git diagnose'), if that is desired in the future.
This introduces one minor change to the output of 'scalar diagnose', which
is that the prefix of the created zip archive is changed from 'scalar_' to

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.

Move the core functionality of 'scalar diagnose' into a new 'diagnose.[c,h]'
library to prepare for new callers in the main Git tree generating
diagnostic archives. These callers will be introduced in subsequent patches.
While this patch appears large, it is mostly made up of moving code out of
'scalar.c' and into 'diagnose.c'. Specifically, the functions
- dir_file_stats_objects()
- dir_file_stats()
- count_files()
- loose_objs_stats()
- add_directory_to_archiver()
are all copied verbatim from 'scalar.c'. The 'create_diagnostics_archive()'
function is a mostly identical (partial) copy of 'cmd_diagnose()', with the
primary changes being that 'zip_path' is an input and "Enlistment root" is
corrected to "Repository root" in the archiver log.

This patch prepares for that change, at which point this platform-specific

* '#ifdef WIN32' is replaced with '#ifdef GIT_WINDOWS_NATIVE' to allow
'statvfs' to be used with Cygwin.
* the 'struct strbuf buf' and 'int res' (as well as their corresponding

If a directory added to the 'scalar diagnose' archiver does not exist, warn
and return 0 from 'add_directory_to_archiver()' rather than failing with a
fatal error. This handles a failure edge case where the '.git/logs' has not
yet been created when running 'scalar diagnose', but extends to any
situation where a directory may be missing in the '.git' dir.
Now, when a directory is missing a warning is captured in the diagnostic

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:

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.

* rs/cocci-array-copy:
cocci: avoid normalization rules for memcpy
Update git-credential-osxkeychain.c to remove 'format string is not a string
literal (potentially insecure)' compiler warning by treating the string as
an argument.

Users may have configured "git merge" to always require GPG
signing the resulting commits. We are not running "git merge" to
re-create merge commits, but merely to replay merge conflicts,
and we will immediately discard the resulting commits; there
is no point in signing them.
Override such configuration that forces useless signing from the
command line with the "--no-gpg-sign" option.

Add Coccinelle rules to detect the pattern of initializing and then
finalizing a structure without using it in between at all, which
happens after code restructuring and the compilers fail to
recognize as an unused variable.
* ab/cocci-unused:
cocci: generalize "unused" rule to cover more than "strbuf"
cocci: add and apply a rule to find "unused" strbufs
cocci: have "coccicheck{,-pending}" depend on "coccicheck-test"
cocci: add a "coccicheck-test" target and test *.cocci rules
Makefile & .gitignore: ignore & clean "git.res", not "*.res"
Makefile: remove mandatory "spatch" arguments from SPATCH_FLAGS
Adapt the content from 'contrib/scalar/README.md' into a design document in
'Documentation/technical/'. In addition to reformatting for asciidoc,
elaborate on the background, purpose, and design choices that went into
Scalar.
Most of this document will persist in the 'Documentation/technical/' after
Scalar has been moved out of 'contrib/' and into the root of Git. Until that
time, it will also contain a temporary "Roadmap" section detailing the
remaining series needed to finish the initial version of Scalar. The section
will be removed once Scalar is moved to the repo root, but in the meantime
serves as a guide for readers to keep up with progress on the feature.

Rephrase documentation to describe scalar as a "large repo management tool"
rather than an "opinionated management tool". The new description is
intended to more directly reflect the utility of scalar to better guide
users in preparation for scalar being built and installed as part of Git.

Further preparation to turn git-submodule.sh into a builtin.
* ab/submodule-cleanup:
git-sh-setup.sh: remove "say" function, change last users
git-submodule.sh: use "$quiet", not "$GIT_QUIET"
submodule--helper: eliminate internal "--update" option
submodule--helper: understand --checkout, --merge and --rebase synonyms
submodule--helper: report "submodule" as our name in some "-h" output
submodule--helper: rename "absorb-git-dirs" to "absorbgitdirs"
submodule update: remove "-v" option
submodule--helper: have --require-init imply --init
git-submodule.sh: remove unused top-level "--branch" argument
git-submodule.sh: make the "$cached" variable a boolean
git-submodule.sh: remove unused $prefix variable
git-submodule.sh: remove unused sanitize_submodule_env()
Some of the rules for using COPY_ARRAY instead of memcpy with sizeof are
intended to reduce the number of sizeof variants to deal with. They can
have unintended side effects if only they match, but not the one for the
COPY_ARRAY conversion at the end.
Avoid these side effects by instead using a self-contained rule for each
combination of array and pointer for source and destination which lists
all sizeof variants inline.
This lets "make contrib/coccinelle/array.cocci.patch" take 15% longer on
my machine, but gives peace of mind that no incomplete transformation
will be generated.

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.

Remove the "say" function, with various rewrites of the remaining
git-*.sh code to C and the preceding change to have git-submodule.sh
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 remaining in-tree hits from "say" are all for the sibling function
defined in t/test-lib.sh. It's safe to remove this function since it
has never been documented in Documentation/git-sh-setup.txt.
