config: drop `git_config_get_string_multi()` wrapper

2025-07-23T15:15:19Z

In 036876a1067 (config: hide functions using `the_repository` by default, 2024-08-13) we have moved around a bunch of functions in the config subsystem that depend on `the_repository`. Those function have been converted into mere wrappers around their equivalent function that takes in a repository as parameter, and the intent was that we'll eventually remove those wrappers to make the dependency on the global repository variable explicit at the callsite. Follow through with that intent and remove `git_config_get_string_multi()`. All callsites are adjusted so that they use `repo_config_get_string_multi(the_repository, ...)` instead. While some callsites might already have a repository available, this mechanical conversion is the exact same as the current situation and thus cannot cause any regression. Those sites should eventually be cleaned up in a later patch series. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

object-file: get rid of `the_repository` in loose object iterators

2025-07-17T05:16:17Z

The iterators for loose objects still rely on `the_repository`. Refactor them: - `for_each_loose_file_in_objdir()` is refactored so that the caller is now expected to pass an `odb_source` as parameter instead of the path to that source. Furthermore, it is renamed accordingly to `for_each_loose_file_in_source()`. - `for_each_loose_object()` is refactored to take in an object database now and calls the above function in a loop. This allows us to get rid of the global dependency. Adjust callers accordingly. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

odb: rename `oid_object_info()`

2025-07-01T21:46:37Z

Rename `oid_object_info()` to `odb_read_object_info()` as well as their `_extended()` variant to match other functions related to the object database and our modern coding guidelines. Introduce compatibility wrappers so that any in-flight topics will continue to compile. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

object-store: move function declarations to their respective subsystems

2025-04-29T17:08:12Z

We carry declarations for a couple of functions in "object-store.h" that are not defined in "object-store.c", but in a different subsystem. Move these declarations to the respective headers whose matching code files carry the corresponding definition. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

Merge branch 'ps/cat-file-filter-batch'

2025-04-16T20:54:21Z

"git cat-file --batch" and friends learned to allow "--filter=" to omit certain objects, just like the transport layer does. * ps/cat-file-filter-batch: builtin/cat-file: use bitmaps to efficiently filter by object type builtin/cat-file: deduplicate logic to iterate over all objects pack-bitmap: introduce function to check whether a pack is bitmapped pack-bitmap: add function to iterate over filtered bitmapped objects pack-bitmap: allow passing payloads to `show_reachable_fn()` builtin/cat-file: support "object:type=" objects filter builtin/cat-file: support "blob:limit=" objects filter builtin/cat-file: support "blob:none" objects filter builtin/cat-file: wire up an option to filter objects builtin/cat-file: introduce function to report object status builtin/cat-file: rename variable that tracks usage

object-store: merge "object-store-ll.h" and "object-store.h"

2025-04-15T15:24:37Z

The "object-store-ll.h" header has been introduced to keep transitive header dependendcies and compile times at bay. Now that we have created a new "object-store.c" file though we can easily move the last remaining additional bit of "object-store.h", the `odb_path_map`, out of the header. Do so. As the "object-store.h" header is now equivalent to its low-level alternative we drop the latter and inline it into the former. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

pack-bitmap: allow passing payloads to `show_reachable_fn()`

2025-04-07T21:43:51Z

The `show_reachable_fn` callback is used by a couple of functions to present reachable objects to the caller. The function does not provide a way for the caller to pass a payload though, which is functionality that we'll require in a subsequent commit. Change the callback type to accept a payload and adapt all callsites accordingly. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

object: stop depending on `the_repository`

2025-03-10T20:16:18Z

There are a couple of functions exposed by "object.c" that implicitly depend on `the_repository`. Remove this dependency by injecting the repository via a parameter. Adapt callers accordingly by simply using `the_repository`, except in cases where the subsystem is already free of the repository. In that case, we instead pass the repository provided by the caller's context. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano
