Code clean-up around object access API. * ps/object-store: odb: rename `read_object_with_reference()` odb: rename `pretend_object_file()` odb: rename `has_object()` odb: rename `repo_read_object_file()` odb: rename `oid_object_info()` odb: trivial refactorings to get rid of `the_repository` odb: get rid of `the_repository` when handling submodule sources odb: get rid of `the_repository` when handling the primary source odb: get rid of `the_repository` in `for_each()` functions odb: get rid of `the_repository` when handling alternates odb: get rid of `the_repository` in `odb_mkstemp()` odb: get rid of `the_repository` in `assert_oid_type()` odb: get rid of `the_repository` in `find_odb()` odb: introduce parent pointers object-store: rename files to "odb.{c,h}" object-store: rename `object_directory` to `odb_source` object-store: rename `raw_object_store` to `object_database`

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

odb: get rid of `the_repository` in `odb_mkstemp()`

2025-07-01T21:46:35Z

Get rid of our dependency on `the_repository` in `odb_mkstemp()` by passing in the object database as a parameter and adjusting all callers. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

object-store: rename files to "odb.{c,h}"

2025-07-01T21:46:34Z

In the preceding commits we have renamed the structures contained in "object-store.h" to `struct object_database` and `struct odb_backend`. As such, the code files "object-store.{c,h}" are confusingly named now. Rename them to "odb.{c,h}" accordingly. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

BUG(): remove leading underscore of the format string

BUG() is not end-user facing but programmer facing, and we do not use _("...") in them. Replace all `BUG(_("..."))` with `BUG("...")` Signed-off-by: Lidong Yan <502024330056@smail.nju.edu.cn> Signed-off-by: Junio C Hamano

2025-04-15T20:50:15Z

The object layer has been updated to take an explicit repository instance as a parameter in more code paths. * ps/object-wo-the-repository: hash: stop depending on `the_repository` in `null_oid()` hash: fix "-Wsign-compare" warnings object-file: split out logic regarding hash algorithms delta-islands: stop depending on `the_repository` object-file-convert: stop depending on `the_repository` pack-bitmap-write: stop depending on `the_repository` pack-revindex: stop depending on `the_repository` pack-check: stop depending on `the_repository` environment: move access to "core.bigFileThreshold" into repo settings pack-write: stop depending on `the_repository` and `the_hash_algo` object: stop depending on `the_repository` csum-file: stop depending on `the_repository`

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

midx: implement writing incremental MIDX bitmaps

2025-03-21T11:34:16Z

Now that the pack-bitmap machinery has learned how to read and interact with an incremental MIDX bitmap, teach the pack-bitmap-write.c machinery (and relevant callers from within the MIDX machinery) to write such bitmaps. The details for doing so are mostly straightforward. The main changes are as follows: - find_object_pos() now makes use of an extra MIDX parameter which is used to locate the bit positions of objects which are from previous layers (and thus do not exist in the current layer's pack_order field). (Note also that the pack_order field is moved into struct write_midx_context to further simplify the callers for write_midx_bitmap()). - bitmap_writer_build_type_index() first determines how many objects precede the current bitmap layer and offsets the bits it sets in each respective type-level bitmap by that amount so they can be OR'd together.
