2024-08-22reftable/generic: drop interfacePatrick Steinhardt
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.

2024-08-22t/helper: inline `reftable_dump_main()`Patrick Steinhardt
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.

2024-08-20t: migrate t0110-urlmatch-normalization to the new frameworkGhanshyam Thakkar
helper/test-urlmatch-normalization along with 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 agnostic in unit tests, since they iterate over entries with the same keys and we do not guarantee the order. This was already done for the 'iterate' tests[1]. The helper/test-hashmap.c is still not removed because it contains a performance test meant to be run by the user directly (not used in t/perf).

2024-07-18Makefile: drop -Wno-universal-initializer from SP_EXTRA_FLAGSRamsay Jones
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.

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.

2024-06-11Makefile: add ability to append to CFLAGS and LDFLAGSPatrick Steinhardt
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.

2024-06-06builtin/refs: new command to migrate ref storage formatsPatrick Steinhardt
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. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2024-06-06Makefile: extract script to lint missing/extraneous manpagesPatrick Steinhardt
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. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>

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_*()).

2024-05-06unit tests: add rule for running with test-toolJosh Steadmon
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.

2024-05-06t0080: turn t-basic unit test into a helperJosh Steadmon
While t/unit-tests/t-basic.c uses the unit-test framework added in e137fe3b29 (unit tests: add TAP unit test framework, 2023-11-09), it is not a true unit test in that it intentionally fails in order to exercise various codepaths in the unit-test framework. Thus, we intentionally exclude it when running unit tests through the various t/Makefile targets. Instead, it is executed by t0080-unit-test-output.sh, which verifies its output follows the TAP format expected for the various pass, skip, or fail cases. As such, it makes more sense for t-basic to be a helper item for t0080-unit-test-output.sh, so let's move it to t/helper/test-example-tap.c and adjust Makefiles as necessary.

2024-05-02trailer: add unit tests for trailer iteratorLinus Arver
Test the number of trailers found by the iterator (to be more precise, the parsing mechanism which the iterator just walks over) when given some arbitrary log message. We test the iterator because it is a public interface function exposed by the trailer API (we generally don't want to test internal implementation details which are, unlike the API, subject to drastic changes).

2024-04-30Merge branch 'js/build-fuzz-more-often'Junio C Hamano
In addition to building the objects needed, try to link the objects that are used in fuzzer tests, to make sure at least they build without bitrot, in Linux CI runs. * js/build-fuzz-more-often: fuzz: link fuzz programs with `make all` on Linux
2024-04-24fuzz: link fuzz programs with `make all` on LinuxJosh Steadmon
Since 5e47215080 (fuzz: add basic fuzz testing target., 2018-10-12), we have compiled object files for the fuzz tests as part of the default 'make all' target. This helps prevent bit-rot in lesser-used parts of the codebase, by making sure that incompatible changes are caught at build time. However, since we never linked the fuzzer executables, this did not protect us from link-time errors. As of 8b9a42bf48 (fuzz: fix fuzz test build rules, 2024-01-19), it's now possible to link the fuzzer executables without using a fuzzing engine and a variety of compiler-specific (and compiler-version-specific) flags, at least on Linux. So let's add a platform-specific option in config.mak.uname to link the executables as part of the default `make all` target. Since linking the fuzzer executables without a fuzzing engine does not require a C++ compiler, we can change the FUZZ_PROGRAMS build rule to use $(CC) by default. This avoids compiler mis-match issues when overriding $(CC) but not $(CXX). When we *do* want to actually link with a fuzzing engine, we can set $(FUZZ_CXX). The build instructions in the CI fuzz-smoke-test job and in the Makefile comment have been updated accordingly. While we're at it, we can consolidate some of the fuzzer build instructions into one location in the Makefile.

2024-04-08reftable: remove name checksPatrick Steinhardt
In the preceding commit we have disabled name checks in the "reftable" backend. These checks were responsible for verifying multiple things when writing records to the reftable stack: - Detecting file/directory conflicts. Starting with the preceding commits this is now handled by the reftable backend itself via `refs_verify_refname_available()`. - Validating refnames. This is handled by `check_refname_format()` in the generic ref transacton layer. The code in the reftable library is thus not used anymore and likely to bitrot over time. Remove it.

2024-04-08Makefile(s): avoid recipe prefix in conditional statementsTaylor Blau
In GNU Make commit 07fcee35 ([SV 64815] Recipe lines cannot contain conditional statements, 2023-05-22) and following, conditional statements may no longer be preceded by a tab character (which Make refers to as the recipe prefix). There are a handful of spots in our various Makefile(s) which will break in a future release of Make containing 07fcee35. For instance, trying to compile the pre-image of this patch with the tip of make.git results in the following: $ make -v | head -1 && make GNU Make 4.4.90 config.mak.uname:842: *** missing 'endif'. Stop. The kernel addressed this issue in 82175d1f9430 (kbuild: Replace tabs with spaces when followed by conditionals, 2024-01-28). Address the issues in Git's tree by applying the same strategy. When a conditional word (ifeq, ifneq, ifdef, etc.) is preceded by one or more tab characters, replace each tab character with 8 space characters with the following: find . -type f -not -path './.git/*' -name Makefile -or -name '*.mak' | xargs perl -i -pe ' s/(\t+)(ifn?eq|ifn?def|else|endif)/" " x (length($1) * 8) . $2/ge unless /\\$/ ' The "unless /\\$/" removes any false-positives (like "\telse \" appearing within a shell script as part of a recipe). After doing so, Git compiles on newer versions of Make: $ make -v | head -1 && make GNU Make 4.4.90 GIT_VERSION = 2.44.0.414.gfac1dc44ca9 [...] $ echo $? 0 Reported-by: Dario Gjorgjevski <dario.gjorgjevski@gmail.com> Signed-off-by: Taylor Blau <me@ttaylorr.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Introduce a new midx-write.c source file, which holds all of the functionality from the MIDX sub-system related to writing new MIDX files. Similar to the relationship between "pack-bitmap.c" and "pack-bitmap-write.c", this source file will hold code that is specific to writing MIDX files as opposed to reading them (the latter will remain in midx.c).
