treewide: remove unnecessary includes in source files

2023-12-26T20:04:31Z

Each of these were checked with gcc -E -I. ${SOURCE_FILE} | grep ${HEADER_FILE} to ensure that removing the direct inclusion of the header actually resulted in that header no longer being included at all (i.e. that no other header pulled it in transitively). ...except for a few cases where we verified that although the header was brought in transitively, nothing from it was directly used in that source file. These cases were: * builtin/credential-cache.c * builtin/pull.c * builtin/send-pack.c Signed-off-by: Elijah Newren Signed-off-by: Junio C Hamano

git-compat-util: move alloc macros to git-compat-util.h

2023-07-05T18:42:31Z

alloc_nr, ALLOC_GROW, and ALLOC_GROW_BY are commonly used macros for dynamic array allocation. Moving these macros to git-compat-util.h with the other alloc macros focuses alloc.[ch] to allocation for Git objects and additionally allows us to remove inclusions to alloc.h from files that solely used the above macros.

treewide: include parse-options.h in source files

2023-03-20T18:26:47Z

The builtins 'ls-remote', 'pack-objects', 'receive-pack', 'reflog' and 'send-pack' use parse_options(), but their source files don't directly include 'parse-options.h'. Furthermore, the source files 'diagnose.c', 'list-objects-filter-options.c', 'remote.c' and 'send-pack.c' define option parsing callback functions, while 'revision.c' defines an option parsing helper function, and thus need access to various fields in 'struct option' and 'struct parse_opt_ctx_t', but they don't directly include 'parse-options.h' either. They all can still be built, of course, because they include one of the header files that does include 'parse-options.h' (though unnecessarily, see the next commit). Add those missing includes to these files, as our general rule is that "a C file must directly include the header files that declare the functions and the types it uses".

alloc.h: move ALLOC_GROW() functions from cache.h

2023-02-24T01:25:28Z

This allows us to replace includes of cache.h with includes of the much smaller alloc.h in many places. It does mean that we also need to add includes of alloc.h in a number of C files. Signed-off-by: Elijah Newren Signed-off-by: Junio C Hamano

list-objects-filter: remove OPT_PARSE_LIST_OBJECTS_FILTER_INIT()

2022-11-30T01:00:35Z

OPT_PARSE_LIST_OBJECTS_FILTER_INIT() with a non-NULL second argument passes a function pointer via an object pointer, which is undefined. It may work fine on platforms that implement C99 extension J.5.7 (Function pointer casts). Remove the unused macro and avoid the dependency on that extension.

list-objects-filter: initialize sub-filter structs

2022-09-22T19:43:04Z

Since commit c54980ab83 (list-objects-filter: convert filter_spec to a strbuf, 2022-09-11), building with SANITIZE=undefined triggers an error in t5616. The problem is that we end up with a strbuf that has been zero-initialized instead of via STRBUF_INIT. Feeding that strbuf to strbuf_addbuf() in list_objects_filter_copy() means we will call memcpy like: memcpy(some_actual_buffer, NULL, 0); This works on most systems because we're copying zero bytes, but it is technically undefined behavior to ever pass NULL to memcpy. Even though c54980ab83 is where the bug manifests, that is only because we switched away from a string_list, which is OK with being zero-initialized (though it may cause other problems by not duplicating the strings, it happened to be OK in this instance). The actual bug is caused by the commit before that, 2a01bdedf8 (list-objects-filter: add and use initializers, 2022-09-11). There we consistently initialize the top-level filter structs, but we forgot the dynamically allocated ones we stick in filter_options->sub when creating combined filters. Note that we need to fix two spots here: where we parse a "combine:" filter, but also where we transform from a single-filter into a combined one after seeing multiple "--filter" options. In the second spot, we'll do some minor refactoring to avoid repeating our very-long array index. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

list-objects-filter: convert filter_spec to a strbuf

2022-09-12T15:38:59Z

Originally, the filter_spec field was just a string pointer. In cf9ceb5a12 (list-objects-filter-options: make filter_spec a string_list, 2019-06-27) it became a string_list, but that commit notes: A strbuf would seem to be a more natural choice for this object, but it unfortunately requires initialization besides just zero'ing out the memory. This results in all container structs, and all containers of those structs, etc., to also require initialization. Initializing them all would be more cumbersome that simply using a string_list, which behaves properly when its contents are zero'd. Now that we've changed the struct to require non-zero initialization anyway (ironically, because string_list also needed non-zero initialization to avoid leaks), we can now convert to that more natural type. This makes the list_objects_filter_spec() function much less awkward, as it had to collapse the string_list to a single-entry list on the fly. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano
