The "check" Makefile target is essentially an alias around the "sparse"
target. The one difference though is that it will tell users to instead
run the "test" target in case they do not have sparse(1) installed, as
chances are high that they wanted to execute the test suite rather than
doing semantic checks.
But even though the "check" target ultimately just ends up executing
`make sparse`, it still depends on our generated headers. This does not
make any sense though: they are irrelevant for the "test" target advice,
and if these headers are required for the "sparse" target they must be
declared as a dependency on the aliased target, not the alias.
But even moving the dependency to the "sparse" target is wrong, as
concurrent builds may then end up generating the headers and running
sparse concurrently. Instead, we make them a dependency of the specific
objects. While that is overly broad, it does ensure correct ordering.
The alternative, specifying which file depends on what generated header
explicitly, feels rather unmaintainable.

Our unit testing framework is a homegrown solution. While it supports
most of our needs, it is likely that the volume of unit tests will grow
quite a bit in the future such that we can exercise low-level subsystems
directly. This surfaces several shortcomings that the current solution
has:
- There is no way to run only one specific tests. While some of our
unit tests wire this up manually, others don't. In general, it
requires quite a bit of boilerplate to get this set up correctly.
- Failures do not cause a test to stop execution directly. Instead,
the test author needs to return manually whenever an assertion
fails. This is rather verbose and is not done correctly in most of
our unit tests.
- Wiring up a new testcase requires both implementing the test
function and calling it in the respective test suite's main
function, which is creating code duplication.
We can of course fix all of these issues ourselves, but that feels
rather pointless when there are already so many unit testing frameworks
out there that have those features.
We line out some requirements for any unit testing framework in
"Documentation/technical/unit-tests.txt". The "clar" unit testing
framework, which isn't listed in that table yet, ticks many of the
boxes:
- It is licensed under ISC, which is compatible.
- It is easily vendorable because it is rather tiny at around 1200
lines of code.
- It is easily hackable due to the same reason.
- It has TAP support.
- It has skippable tests.
- It preprocesses test files in order to extract test functions, which
then get wired up automatically.
While it's not perfect, the fact that clar originates from the libgit2
project means that it should be rather easy for us to collaborate with
upstream to plug any gaps.
Import the clar unit testing framework at commit 1516124 (Merge pull
request #97 from pks-t/pks-whitespace-fixes, 2024-08-15). The framework
will be wired up in subsequent commits.

oid-array.h API, which provides storage and processing
efficiency over large lists of object identifiers.
Migrate them to the unit testing framework for better runtime
performance and efficiency. As we don't initialize a repository
in these tests, the hash algo that functions like oid_array_lookup()
use is not initialized, therefore call repo_set_hash_algo() to
initialize it. And init_hash_algo():lib-oid.c can aid in this
process, so make it public.

Enable Git to resolve its own binary location using __getprogramdir
and getprogname.
Since /proc is not a mandatory filesystem on z/OS, we cannot rely on the
git_get_exec_path_procfs method to determine Git's executable path. To
address this, we have implemented git_get_exec_path_zos, which resolves
the executable path by extracting it from the current program's
directory and filename.

The `reftable_table` interface provides a generic infrastructure that
can abstract away whether the underlying table is a single table, or a
merged table. This abstraction can make it rather hard to reason about
the code. We didn't ever use it to implement the reftable backend, and
with the preceding patches in this patch series we in fact don't use it
at all anymore. Furthermore, it became somewhat useless with the recent
refactorings that made it possible to seek reftable iterators multiple
times, as these now provide generic access to tables for us. The
interface is thus redundant and only brings unnecessary complexity with
it.
Remove the `struct reftable_table` interface and its associated
functions.

The printing functionality part of `reftable/dump.c` is really only used
by our "dump-reftable" test helper. It is certainly not generic logic
that is useful to anybody outside of Git, and the format it generates is
quite specific. Still, parts of it are used in our test suite and the
output may be useful to take a peek into reftable stacks, tables and
blocks. So while it does not make sense to expose this as part of the
reftable library, it does make sense to keep it around.
Inline the `reftable_dump_main()` function into the "dump-reftable" test
helper. This clarifies that its format is subject to change and not part
of our public interface. Furthermore, this allows us to iterate on the
implementation in subsequent patches.

'urlmatch.h'. Migrate them to the unit testing framework for better
performance. And also add different test_msg()s for better debugging.
In the migration, last two of the checks from `t_url_general_escape()`
were slightly changed compared to the shell script. This involves
changing
'\'' -> '
'\!' -> !
in the urls of those checks. This is because in C strings, we don't
need to escape "'" and "!". Other than these two, all the urls were
pasted verbatim from the shell script.
Another change is the removal of a MINGW prerequisite from one of the
test. It was there because[1] on Windows, the command line is a
Unicode string, it is not possible to pass arbitrary bytes to a
program. But in unit tests we don't have this limitation.
And since we can construct strings with arbitrary bytes in C, let's
also remove the test files which contain URLs with arbitrary bytes in
the 't/t0110' directory and instead embed those URLs in the unit test
code itself.

Commit 1c96642326 ("sparse: allow '{ 0 }' to be used without warnings",
2020-05-22) added -Wno-universal-initializer to the SP_EXTRA_FLAGS in
order to suppress potential sparse warnings from using '{0}' as an
aggregate initializer. At that time, the default was for sparse to
issue warnings (i.e. the default was -Wuniversal-initializer) if such
an initializer was used to initialize an aggregate whose first member
was a pointer type. However, this default was changed just a few days
later to -Wno-universal-initializer (first released in sparse v0.6.2)
and has been so in all subsequent release versions of sparse. Thus,
including -Wno-universal-initializer in the SP_EXTRA_FLAGS variable is
redundant.
Remove the unnecessary warning flag from SP_EXTRA_FLAGS, essentially
reverting commit 1c96642326.

There are some usecases where we may want to append CFLAGS to the
default CFLAGS set by Git. This could for example be to enable or
disable specific compiler warnings or to change the optimization level
that code is compiled with. This cannot be done without overriding the
complete CFLAGS value though and thus requires the user to redeclare the
complete defaults used by Git.
Introduce a new variable `CFLAGS_APPEND` that gets appended to the
default value of `CFLAGS`. As compiler options are last-one-wins, this
fulfills both of the usecases mentioned above. It's also common practice
across many other projects to have such a variable.
While at it, also introduce a matching `LDFLAGS_APPEND` variable. While
there isn't really any need for this variable as there are no default
`LDFLAGS`, users may expect this variable to exist, as well.

Introduce a new command that allows the user to migrate a repository
between ref storage formats. This new command is implemented as part of
a new git-refs(1) executable. This is due to two reasons:
- There is no good place to put the migration logic in existing
commands. git-maintenance(1) felt unwieldy, and git-pack-refs(1) is
not the correct place to put it, either.
- I had it in my mind to create a new low-level command for accessing
refs for quite a while already. git-refs(1) is that command and can
over time grow more functionality relating to refs. This should help
discoverability by consolidating low-level access to refs into a
single executable.
As mentioned in the preceding commit that introduces the ref storage
format migration logic, the new `git refs migrate` command still has a
bunch of restrictions. These restrictions are documented accordingly.

The "check-docs" target of our top-level Makefile fulfills two different
roles. For one it runs the "lint-docs" target of the "Documentation/"
Makefile. And second it performs some checks of whether there are any
manpages that are missing or extraneous via some inline scripts.
The second set of checks feels quite misplaced in the top-level Makefile
as it would fit in much better with our "lint-docs" target. Back when
the checks were introduced in 8c989ec528 (Makefile: $(MAKE) check-docs,
2006-04-13), that target did not yet exist though.
Furthermore, the script makes use of several Makefile variables which
are defined in the top-level Makefile, which makes it hard to access
their contents from elsewhere. There is a trick though that we already
use in "check-builtins.sh" to gain access: we can create an ad-hoc
Makefile that has an extra target to print those variables.
Pull out the script into a separate "lint-manpages.sh" script by using
that trick. Wire up that script via the "lint-docs" target. For one,
normal shell scripts are way easier to reason about than those which are
embedded in a Makefile. Second, it allows one to easily execute the
script standalone without any of the other checks.

The strcmp-offset tests have been rewritten using the unit test
framework.
* gt/unit-test-strcmp-offset:
t/: port helper/test-strcmp-offset.c to unit-tests/t-strcmp-offset.c
reftable/basics_test.c exercise the functions defined in
reftable/basics.{c, h}. Migrate reftable/basics_test.c to the
unit testing framework. Migration involves refactoring the tests
to use the unit testing framework instead of reftable's test
framework.

t/helper/test-{sha1, sha256} and t/t0015-hash.sh test the hash
implementation of SHA-1 and SHA-256 in Git with basic hash values.
Migrate them to the new unit testing framework for better debugging
and runtime performance.
The 'sha1' and 'sha256' subcommands are still not removed due to
pack_trailer():lib-pack.sh's reliance on them. The 'sha1' subcommand
is also relied upon by t0013-sha1dc (which requires 'test-tool
sha1' dying when it is used on a file created to contain the
known sha1 attack).

helper/test-example-decorate.c along with t9004-example.sh provide
an example of how to use the functions in decorate.h (which provides
a data structure that associates Git objects to void pointers) and
also test their output.

and runtime performance.

Add two functions that allow to replace and remove strings contained in
the strvec. This will be used by a subsequent commit that refactors
git-mv(1).
While at it, add a bunch of unit tests that cover both old and new
functionality.

Add a new (empty) header file to contain the implementation for
selecting, reading, and applying pseudo-merge bitmaps.
For now this header and its corresponding implementation are left
empty, but they will evolve over the course of subsequent commit(s).

The trailer API has been reshuffled a bit.
* la/hide-trailer-info:
trailer unit tests: inspect iterator contents
trailer: document parse_trailers() usage
trailer: retire trailer_info_get() from API
trailer: make trailer_info struct private
trailer: make parse_trailers() return trailer_info pointer
interpret-trailers: access trailer_info with new helpers
sequencer: use the trailer iterator
trailer: teach iterator about non-trailer lines
trailer: add unit tests for trailer iterator
Makefile: sort UNIT_TEST_PROGRAMS
In the recent codebase update (8bf6fbd (Merge branch
'js/doc-unit-tests', 2023-12-09)), a new unit testing framework was
merged, providing a standardized approach for testing C code. Prior to
this update, some unit tests relied on the test helper mechanism,
lacking a dedicated unit testing framework. It's more natural to perform
these unit tests using the new unit test framework.
Let's migrate the unit tests for strcmp-offset functionality from the
legacy approach using the test-tool command `test-tool strcmp-offset` in
helper/test-strcmp-offset.c to the new unit testing framework
(t/unit-tests/test-lib.h).
The migration involves refactoring the tests to utilize the testing
macros provided by the framework (TEST() and check_*()).

The "test-tool" has been taught to run testsuite tests in parallel,
bypassing the need to use the "prove" tool.
* js/unit-test-suite-runner:
cmake: let `test-tool` run the unit tests, too
ci: use test-tool as unit test runner on Windows
t/Makefile: run unit tests alongside shell tests
unit tests: add rule for running with test-tool
test-tool run-command testsuite: support unit tests
test-tool run-command testsuite: remove hardcoded filter
test-tool run-command testsuite: get shell from env
t0080: turn t-basic unit test into a helper
Code to write out reftable has seen some optimization and
simplification.
* ps/reftable-write-optim:
reftable/block: reuse compressed array
reftable/block: reuse zstream when writing log blocks
reftable/writer: reset `last_key` instead of releasing it
reftable/writer: unify releasing memory
reftable/writer: refactorings for `writer_flush_nonempty_block()`
reftable/writer: refactorings for `writer_add_record()`
refs/reftable: don't recompute committer ident
reftable: remove name checks
refs/reftable: skip duplicate name checks
refs/reftable: perform explicit D/F check when writing symrefs
refs/reftable: fix D/F conflict error message on ref copy
In the previous commit, we added support in test-tool for running
collections of unit tests. Now, add rules in t/Makefile for running in
this way.
This new rule can be executed from the top-level Makefile via
`make DEFAULT_UNIT_TEST_TARGET=unit-tests-test-tool unit-tests`, or by
setting DEFAULT_UNIT_TEST_TARGET in config.mak.
