refs: add struct repository parameter in get_files_ref_lock_timeout_ms()

2026-04-08T16:58:09Z

get_files_ref_lock_timeout_ms() calls repo_config_get_int() using the_repository, as no repository instance is available in its scope. Add a struct repository parameter and use it instead of the_repository. Update all callers accordingly. In files-backend.c, lock_raw_ref() can obtain repository instance from the struct ref_transaction via transaction->ref_store->repo and pass it down. For create_reflock(), which is used as a callback, introduce a small wrapper struct to pass both struct lock_file and struct repository through the callback data. This reduces reliance on the_repository global, though the function still uses static variables and is not yet fully repository-scoped. This can be addressed in a follow-up change.

refs/files-backend: drop const to fix strchr() warning

2026-04-02T05:08:53Z

In show_one_reflog_ent(), we're fed a writable strbuf buffer, which we parse into the various reflog components. We write a NUL over email_end to tie off one of the fields, and thus email_end must be non-const. But with a C23 implementation of libc, strchr() will now complain when assigning the result to a non-const pointer from a const one. So we can fix this by making the source pointer non-const. But there's a catch. We derive that source pointer by parsing the line with parse_oid_hex_algop(), which requires a const pointer for its out-parameter. We can work around that by teaching it to use our CONST_OUTPARAM() trick, just like skip_prefix(). Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

The HTTP transport learned to react to "429 Too Many Requests". * vp/http-rate-limit-retries: http: add support for HTTP 429 rate limit retries strbuf_attach: fix call sites to pass correct alloc strbuf: pass correct alloc to strbuf_attach() in strbuf_reencode()

strbuf_attach: fix call sites to pass correct alloc

2026-03-17T16:14:19Z

strbuf_attach(sb, buf, len, alloc) requires alloc > len (the buffer must have at least len+1 bytes to hold the NUL). Several call sites passed alloc == len, relying on strbuf_grow(sb, 0) inside strbuf_attach to reallocate. Fix these in mailinfo, am, refs/files-backend, fast-import, and trailer by passing len+1 when the buffer is a NUL-terminated string (or from strbuf_detach).

refs: receive and use the reference storage payload

2026-02-25T17:27:12Z

An upcoming commit will add support for providing an URI via the 'extensions.refStorage' config. The URI will contain the reference backend and a corresponding payload. The payload can be then used for providing an alternate locations for the reference backend. To prepare for this, modify the existing backends to accept such an argument when initializing via the 'init()' function. Both the files and reftable backends will parse the information to be filesystem paths to store references. Given that no callers pass any payload yet this is essentially a no-op change for now. To enable this, provide a 'refs_compute_filesystem_location()' function which will parse the current 'gitdir' and the 'payload' to provide the final reference directory and common reference directory (if working in a linked worktree). The documentation and tests will be added alongside the extension of the config variable. Helped-by: Patrick Steinhardt Signed-off-by: Karthik Nayak Signed-off-by: Junio C Hamano

refs: move out stub modification to generic layer

2026-02-25T17:27:12Z

When creating the reftable reference backend on disk, we create stubs to ensure that the directory can be recognized as a Git repository. This is done by calling `refs_create_refdir_stubs()`. Move this to the generic layer as this is needed for all backends excluding from the files backends. In an upcoming commit where we introduce alternate reference backend locations, we'll have to also create stubs in the $GIT_DIR irrespective of the backend being used. This commit builds the base to add that logic. Similarly, move the logic for deletion of stubs to the generic layer. The files backend recursively calls the remove function of the 'packed-backend', here skip calling the generic function since that would try to delete stubs.
