hook-list.h: add a generated list of hooks, like config-list.h 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.

built-ins: use free() not UNLEAK() if trivial, rm dead code For a lot of uses of UNLEAK() it would be quite tricky to release the memory involved, or we're missing the relevant *_(release|clear)() functions. But in these cases we have them already, and can just invoke them on the variable(s) involved, instead of UNLEAK(). For "builtin/worktree.c" the UNLEAK() was also added in [1], but the struct member it's unleaking was removed in [2]. The only non-"int" member of that structure is "const char *keep_locked", which comes to us via "argv" or a string literal[3]. We have good visibility via the compiler and tooling (e.g. SANITIZE=address) on bad free()-ing, but none on UNLEAK() we don't need anymore. So let's prefer releasing the memory when it's easy. For "bugreport", "worktree" and "config" we need to start using a "ret = ..." return pattern. For "builtin/bugreport.c" these UNLEAK() were added in [4], and for "builtin/config.c" in [1]. For "config" the code seen here was the only user of the "value" variable. For "ACTION_{RENAME,REMOVE}_SECTION" we need to be sure to return the right exit code in the cases where we were relying on falling through to the top-level. I think there's still a use-case for UNLEAK(), but hat it's changed since then. Using it so that "we can see the real leaks" is counter-productive in these cases. It's more useful to have UNLEAK() be a marker of the remaining odd cases where it's hard to free() the memory for whatever reason. With this change less than 20 of them remain in-tree. 1. 0e5bba53af7 (add UNLEAK annotation for reducing leak false positives, 2017-09-08) 2. d861d34a6ed (worktree: remove extra members from struct add_opts, 2018-04-24) 3. 0db4961c49b (worktree: teach `add` to accept --reason <string> with --lock, 2021-07-15) 4. 0e5bba53af7 and 00d8c311050 (commit: fix "author_ident" leak, 2022-05-12).
