refs: always treat iterators as ordered

2024-02-21T17:58:06Z

In the preceding commit we have converted the reflog iterator of the "files" backend to be ordered, which was the only remaining ref iterator that wasn't ordered. Refactor the ref iterator infrastructure so that we always assume iterators to be ordered, thus simplifying the code. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

refs: prepare `refs_init_db()` for initializing worktree refs

2024-01-08T21:17:30Z

The purpose of `refs_init_db()` is to initialize the on-disk files of a new ref database. The function is quite inflexible right now though, as callers can neither specify the `struct ref_store` nor can they pass any flags. Refactor the interface to accept both of these. This will be required so that we can start initializing per-worktree ref databases via the ref backend instead of open-coding the initialization in "worktree.c".

refs: refactor logic to look up storage backends

2024-01-02T17:24:47Z

In order to look up ref storage backends, we're currently using a linked list of backends, where each backend is expected to set up its `next` pointer to the next ref storage backend. This is kind of a weird setup as backends need to be aware of other backends without much of a reason. Refactor the code so that the array of backends is centrally defined in "refs.c", where each backend is now identified by an integer constant. Expose functions to translate from those integer constants to the name and vice versa, which will be required by subsequent patches. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

refs: remove `delete_refs` callback from backends

2023-11-17T01:12:12Z

Now that `refs_delete_refs` is implemented in a generic way via the ref transaction interfaces there are no callers left that invoke the `delete_refs` callback anymore. Remove it from all of our backends. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

Enumerating refs in the packed-refs file, while excluding refs that match certain patterns, has been optimized. * tb/refs-exclusion-and-packed-refs: ls-refs.c: avoid enumerating hidden refs where possible upload-pack.c: avoid enumerating hidden refs where possible builtin/receive-pack.c: avoid enumerating hidden references refs.h: implement `hidden_refs_to_excludes()` refs.h: let `for_each_namespaced_ref()` take excluded patterns revision.h: store hidden refs in a `strvec` refs/packed-backend.c: add trace2 counters for jump list refs/packed-backend.c: implement jump lists to avoid excluded pattern(s) refs/packed-backend.c: refactor `find_reference_location()` refs: plumb `exclude_patterns` argument throughout builtin/for-each-ref.c: add `--exclude` option ref-filter.c: parameterize match functions over patterns ref-filter: add `ref_filter_clear()` ref-filter: clear reachable list pointers after freeing ref-filter.h: provide `REF_FILTER_INIT` refs.c: rename `ref_filter`

refs: plumb `exclude_patterns` argument throughout

2023-07-10T21:48:55Z

The subsequent patch will want to access an optional `excluded_patterns` array within `refs/packed-backend.c` that will cull out certain references matching any of the given patterns on a best-effort basis. To do so, the refs subsystem needs to be updated to pass this value across a number of different locations. Prepare for a future patch by introducing this plumbing now, passing NULLs at top-level APIs in order to make that patch less noisy and more easily readable.

Merge branch 'jc/pack-ref-exclude-include'

2023-06-13T19:29:45Z

"git pack-refs" learns "--include" and "--exclude" to tweak the ref hierarchy to be packed using pattern matching. * jc/pack-ref-exclude-include: pack-refs: teach pack-refs --include option pack-refs: teach --exclude option to exclude refs from being packed docs: clarify git-pack-refs --all will pack all refs

pack-refs: teach --exclude option to exclude refs from being packed

2023-05-12T21:54:14Z

At GitLab, we have a system that creates ephemeral internal refs that don't live long before getting deleted. Having an option to exclude certain refs from a packed-refs file allows these internal references to be deleted much more efficiently. Add an --exclude option to the pack-refs builtin, and use the ref exclusions API to exclude certain refs from being packed into the final packed-refs file Signed-off-by: John Cai Signed-off-by: Junio C Hamano
