hash-ll.h: split out of hash.h to remove dependency on repository.h

2023-04-24T19:47:32Z

hash.h depends upon and includes repository.h, due to the definition and use of the_hash_algo (defined as the_repository->hash_algo). However, most headers trying to include hash.h are only interested in the layout of the structs like object_id. Move the parts of hash.h that do not depend upon repository.h into a new file hash-ll.h (the "low level" parts of hash.h), and adjust other files to use this new header where the convenience inline functions aren't needed. This allows hash.h and object.h to be fairly small, minimal headers. It also exposes a lot of hidden dependencies on both path.h (which was brought in by repository.h) and repository.h (which was previously implicitly brought in by object.h), so also adjust other files to be more explicit about what they depend upon.

range-diff: plug memory leak in common invocation

2022-03-04T21:24:19Z

Create a public release_patch() version of the private free_patch() function added in 13b5af22f39 (apply: move libified code from builtin/apply.c to apply.{c,h}, 2016-04-22). Unlike the existing function this one doesn't free() the "struct patch" itself, so we can use it for variables on the stack. Use it in range-diff.c to fix a memory leak in common range-diff invocations, e.g.: git -P range-diff origin/master origin/next origin/seen Would emit several errors when compiled with SANITIZE=leak, but now runs cleanly.

Merge branch 'rs/apply-symlinks-use-strset'

2022-02-05T17:42:30Z

"git apply" (ab)used the util pointer of the string-list to keep track of how each symbolic link needs to be handled, which has been simplified by using strset. * rs/apply-symlinks-use-strset: apply: use strsets to track symlinks

apply: use strsets to track symlinks

2022-01-07T19:40:44Z

Symlink changes are tracked in a string_list, with the util pointer value indicating whether a symlink is kept or removed. Using fake pointer values requires awkward casts. Use one strset for each type of change instead to simplify and shorten the code. Original-patch-by: Jessica Clarke Signed-off-by: René Scharfe Signed-off-by: Junio C Hamano

git-apply: add --allow-empty flag

2021-12-13T22:30:25Z

Some users or scripts will pipe "git diff" output to "git apply" when replaying diffs or commits. In these cases, they will rely on the return value of "git apply" to know whether the diff was applied successfully. However, for empty commits, "git apply" will fail. This complicates scripts since they have to either buffer the diff and check its length, or run diff again with "exit-code", essentially doing the diff twice. Add the "--allow-empty" flag to "git apply" which allows it to handle both empty diffs and empty commits created by "git format-patch --always" by doing nothing and returning 0. Add tests for both with and without --allow-empty. Signed-off-by: Jerry Zhang Signed-off-by: Junio C Hamano

apply.h: include missing header

2019-09-28T05:04:16Z

When running `make hdr-check`, we got the following error messages: apply.h:146:22: error: use of undeclared identifier 'GIT_MAX_HEXSZ' char old_oid_prefix[GIT_MAX_HEXSZ + 1]; ^ apply.h:147:22: error: use of undeclared identifier 'GIT_MAX_HEXSZ' char new_oid_prefix[GIT_MAX_HEXSZ + 1]; ^ apply.h:151:33: error: array has incomplete element type 'struct object_id' struct object_id threeway_stage[3]; ^ ./strbuf.h:79:8: note: forward declaration of 'struct object_id' struct object_id; ^ 3 errors generated. make: *** [apply.hco] Error 1 Include the missing "hash.h" header to fix these errors.

apply: make parse_git_diff_header public

2019-07-11T21:29:27Z

Make 'parse_git_header()' (renamed to 'parse_git_diff_header()') a "public" function in apply.h, so we can re-use it in range-diff in a subsequent commit. We're renaming the function to make it clearer in other parts of the codebase that we're talking about a diff header and not just any header.

Merge branch 'en/incl-forward-decl'

2018-08-20T19:41:32Z

Code hygiene improvement for the header files. * en/incl-forward-decl: Remove forward declaration of an enum compat/precompose_utf8.h: use more common include guard style urlmatch.h: fix include guard Move definition of enum branch_track from cache.h to branch.h alloc: make allocate_alloc_state and clear_alloc_state more consistent Add missing includes and forward declarations

I looped over the toplevel header files, creating a temporary two-line C program for each consisting of #include "git-compat-util.h" #include $HEADER This patch is the result of manually fixing errors in compiling those tiny programs. Signed-off-by: Elijah Newren Signed-off-by: Junio C Hamano

apply.c: make init_apply_state() take a struct repository

2018-08-13T21:14:44Z

We're moving away from the_index in this code. "struct index_state *" could be added to struct apply_state. But let's aim long term and put struct repository here instead so that we could even avoid more global states in the future. The index will be available via apply_state->repo->index.
