The checksum at the tail of files are now computed without
collision detection protection. This is safe as the consumer of
the information to protect itself from replay attacks checks for
hash collisions independently.
* tb/weak-sha1-for-tail-sum:
csum-file.c: use unsafe SHA-1 implementation when available
Makefile: allow specifying a SHA-1 for non-cryptographic uses
hash.h: scaffolding for _unsafe hashing variants
sha1: do not redefine `platform_SHA_CTX` and friends
pack-objects: use finalize_object_file() to rename pack/idx/etc
finalize_object_file(): implement collision check
finalize_object_file(): refactor unlink_or_warn() placement
finalize_object_file(): check for name collision before renaming

Introduce _UNSAFE variants of the OPENSSL_SHA1, BLK_SHA1, and
APPLE_COMMON_CRYPTO_SHA1 compile-time knobs which indicate which SHA-1
implementation is to be used for non-cryptographic uses.
There are a couple of small implementation notes worth mentioning:
- There is no way to select the collision detecting SHA-1 as the
"fast" fallback, since the fast fallback is only for
non-cryptographic uses, and is meant to be faster than our
collision-detecting implementation.
- There are no similar knobs for SHA-256, since no collision attacks
are presently known and thus no collision-detecting implementations
actually exist.

In 67ce50ba26 (Merge branch 'ps/reftable-reusable-iterator', 2024-05-30)
we have refactored the interface of reftable iterators such that they
can be reused in theory. This patch series only landed the required
changes on the interface level, but didn't yet implement the actual
logic to make iterators reusable.
As it turns out almost all of the infrastructure already does support
re-seeking. The only exception is the table iterator, which does not
reset its `is_finished` bit. Do so and add a couple of tests that verify
that we can re-seek iterators.

We have recently migrated all of the reftable unit tests that were part
of the reftable library into our own unit testing framework. As part of
that migration we have duplicated some of the functionality that was
part of the reftable test framework into each of the migrated test
suites. This was a sensible decision to not have all of the migrations
dependent on each other, but now that the migration is done it makes
sense to deduplicate the functionality again.
Introduce a new reftable test library that hosts some shared code and
adapt tests to use it.

Whenever one adds another test library compilation unit one has to wire
it up twice in the Makefile: once to append it to `UNIT_TEST_OBJS`, and
once to append it to the `UNIT_TEST_PROGS` target. Ideally, we'd just
reuse the `UNIT_TEST_OBJS` variable in the target so that we can avoid
the duplication. But it also contains all the objects for our test
programs, each of which contains a `cmd_main()`, and thus we cannot link
them all into the target executable.
Refactor the code such that `UNIT_TEST_OBJS` does not contain the unit
test program objects anymore, which we can instead manually append to
the `OBJECTS` variable. Like this, the former variable now only contains
objects for test libraries and can thus be reused.

The Makefile variables related to the recently-introduced clar testing
framework have a `UNIT_TESTS_` prefix. This prefix is extremely similar
to the prefix used by our other unit tests that use our homegrown unit
testing framework, which is `UNIT_TEST_`. The consequence is that it is
easy to misread the names and confuse them with each other.
Rename the clar-related variables to instead have a `CLAR_TEST_` prefix
to address this.

reftable/stack_test.c exercises the functions defined in
reftable/stack.{c, h}. Migrate reftable/stack_test.c to the
unit testing framework. Migration involves refactoring the tests
to use the unit testing framework instead of reftable's test
framework and renaming the tests to be in-line with unit-tests'
standards.
Since some of the tests use set_test_hash() defined by
reftable/test_framework.{c, h} but these files are not
'#included' in the test file, copy this function in the
ported test file.
With the migration of stack test to the unit-tests framework,
"test-tool reftable" becomes a no-op. Hence, get rid of everything
that uses "test-tool reftable" alongside everything that is used
to implement it.
While at it, alphabetically sort the cmds[] list in
helper/test-tool.c by moving the entry for "dump-reftable".

Convert the strvec tests to use the new clar unit testing framework.
This is a first test balloon that demonstrates how the testing infra for
clar-based tests looks like.
The tests are part of the "t/unit-tests/bin/unit-tests" binary. When
running that binary with an injected error, it generates TAP output:

The binary also supports some parameters that allow us to run only a
subset of unit tests or alter the output:
$ ./t/unit-tests/bin/unit-tests -h
Usage: ./t/unit-tests/bin/unit-tests [options]
Options:

-q Only report tests that had an error
-Q Quit as soon as a test fails
-t Display results in tap format
-l Print suite names

Wire up the clar unit testing framework by introducing a new
"unit-tests" executable. In contrast to the existing framework, this
will result in a single executable for all test suites. The ability to
pick specific tests to execute is retained via functionality built into
the clar itself.
Note that we need to be a bit careful about how we need to invalidate
our Makefile rules. While we obviously have to regenerate the clar suite
when our test suites change, we also have to invalidate it in case any
of the test suites gets removed. We do so by using our typical pattern
of creating a `GIT-TEST-SUITES` file that gets updated whenever the set
of test suites changes, so that we can easily depend on that file.
Another specialty is that we generate a "clar-decls.h" file. The test
functions are neither static, nor do they have external declarations.
This is because they are getting parsed via "generate.py", which then
creates the external generations that get populated into an array. These
declarations are only seen by the main function though.
The consequence is that we will get a bunch of "missing prototypes"
errors from our compiler for each of these test functions. To fix those
errors, we extract the `extern` declarations from "clar.suite" and put
them into a standalone header that then gets included by each of our
unit tests. This gets rid of compiler warnings for every function which
has been extracted by "generate.py". More importantly though, it does
_not_ get rid of warnings in case a function really isn't being used by
anything. Thus, it would cause a compiler error if a function name was
mistyped and thus not picked up by "generate.py".
The test driver "unit-test.c" is an empty stub for now. It will get
implemented in the next commit.

The "hdr-check" Makefile target compiles each of our headers as a
standalone code unit to ensure that they are not missing any type
declarations and can be included standalone.
With the next commit we will wire up the clar unit testing framework,
which will have the effect that some headers start depending on
generated ones. While we could declare that dependency explicitly, it
does not really feel very maintainable in the future.
Instead, we do the same as in the preceding commit and have the objects
depend on all of our generated headers. While again overly broad, it is
easy to maintain and generating headers is not an expensive thing to do
anyway.

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.

Migrate them to the unit testing framework for better runtime

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

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

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.

t0110-urlmatch-normalization test the `url_normalize()` function from
'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.

Along with the migration, make 'add' tests from the shell script order

reftable/pq.{c, h}. Migrate reftable/pq_test.c to the unit testing
framework. Migration involves refactoring the tests to use the unit
testing framework instead of reftable's test framework, and
renaming the tests to align with unit-tests' standards.

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.

t-reftable-record: add log tests for reftable_record_is_deletion()
t-reftable-record: add ref tests for reftable_record_is_deletion()
t-reftable-record: add comparison tests for obj records
t-reftable-record: add comparison tests for index records
t-reftable-record: add comparison tests for ref records
t-reftable-record: add reftable_record_cmp() tests for log records
t: move reftable/record_test.c to the unit testing framework

reftable/merged_test.c exercises the functions defined in
reftable/merged.{c, h}. Migrate reftable/merged_test.c to the unit
testing framework. Migration involves refactoring the tests
to use the unit testing framework instead of reftable's test
framework and renaming the tests according to unit-tests' naming
conventions.
Also, move strbuf_add_void() and noop_flush() from
reftable/test_framework.c to the ported test. This is because
both these functions are used in the merged tests and
reftable/test_framework.{c, h} is not #included in the ported test.

helper/test-oidmap.c along with t0016-oidmap.sh test the oidmap.h
library which is built on top of hashmap.h.
Migrate them to the unit testing framework for better performance,
concise code and better debugging. Along with the migration also plug
memory leaks and make the test logic independent for all the tests.
The migration removes 'put' tests from t0016, because it is used as
setup to all the other tests, so testing it separately does not yield
any benefit.

reftable/record_test.c exercises the functions defined in
reftable/record.{c, h}. Migrate reftable/record_test.c to the
unit testing framework. Migration involves refactoring the tests
to use the unit testing framework instead of reftable's test
framework, and renaming the tests to fit unit-tests' naming scheme.
While at it, change the type of index variable 'i' to 'size_t'
from 'int'. This is because 'i' is used in comparison against
'ARRAY_SIZE(x)' which is of type 'size_t'.
Also, use set_hash() which is defined locally in the test file
instead of set_test_hash() which is defined by
reftable/test_framework.{c, h}. This is fine to do as both these
functions are similarly implemented, and
reftable/test_framework.{c, h} is not #included in the ported test.
Get rid of reftable_record_print() from the tests as well, because
it clutters the test framework's output and we have no way of
verifying the output.
