odb: introduce `odb_write_object()`

2025-07-17T05:16:15Z

We do not have a backend-agnostic way to write objects into an object database. While there is `write_object_file()`, this function is rather specific to the loose object format. Introduce `odb_write_object()` to plug this gap. For now, this function is a simple wrapper around `write_object_file()` and doesn't even use the passed-in object database yet. This will change in subsequent commits, where `write_object_file()` is converted so that it works on top of an `odb_source`. `odb_write_object()` will then become responsible for deciding which source an object shall be written to.

odb: rename `repo_read_object_file()`

2025-07-01T21:46:38Z

Rename `repo_read_object_file()` to `odb_read_object()` to match other functions related to the object database and our modern coding guidelines. Introduce a compatibility wrapper so that any in-flight topics will continue to compile. 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

object-file: split out functions relating to object store subsystem

2025-04-15T15:24:36Z

While we have the "object-store.h" header, most of the functionality for object stores is actually hosted in "object-file.c". This makes it hard to find relevant functions and causes us to mix up concerns. Split out functions relating to the object store subsystem into a new "object-store.c" file.

global: introduce `USE_THE_REPOSITORY_VARIABLE` macro

2024-06-14T17:26:33Z

Use of the `the_repository` variable is deprecated nowadays, and we slowly but steadily convert the codebase to not use it anymore. Instead, callers should be passing down the repository to work on via parameters. It is hard though to prove that a given code unit does not use this variable anymore. The most trivial case, merely demonstrating that there is no direct use of `the_repository`, is already a bit of a pain during code reviews as the reviewer needs to manually verify claims made by the patch author. The bigger problem though is that we have many interfaces that implicitly rely on `the_repository`. Introduce a new `USE_THE_REPOSITORY_VARIABLE` macro that allows code units to opt into usage of `the_repository`. The intent of this macro is to demonstrate that a certain code unit does not use this variable anymore, and to keep it from new dependencies on it in future changes, be it explicit or implicit For now, the macro only guards `the_repository` itself as well as `the_hash_algo`. There are many more known interfaces where we have an implicit dependency on `the_repository`, but those are not guarded at the current point in time. Over time though, we should start to add guards as required (or even better, just remove them). Define the macro as required in our code units. As expected, most of our code still relies on the global variable. Nearly all of our builtins rely on the variable as there is no way yet to pass `the_repository` to their entry point. For now, declare the macro in "biultin.h" to keep the required changes at least a little bit more contained. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

cocci: apply rules to rewrite callers of "refs" interfaces

Apply the rules that rewrite callers of "refs" interfaces to explicitly pass `struct ref_store`. The resulting patch has been applied with the `--whitespace=fix` option. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

object-store-ll.h: split this header out of object-store.h

2023-06-21T20:39:54Z

The vast majority of files including object-store.h did not need dir.h nor khash.h. Split the header into two files, and let most just depend upon object-store-ll.h, while letting the two callers that need it depend on the full object-store.h. After this patch: $ git grep -h include..object-store | sort | uniq -c 2 #include "object-store.h" 129 #include "object-store-ll.h" Diff best viewed with `--color-moved`.

libs: use "struct repository *" argument, not "the_repository"

2023-03-28T14:36:46Z

As can easily be seen from grepping in our sources, we had these uses of "the_repository" in various library code in cases where the function in question was already getting a "struct repository *" argument. Let's use that argument instead. Out of these changes only the changes to "cache-tree.c", "commit-reach.c", "shallow.c" and "upload-pack.c" would have cleanly applied before the migration away from the "repo_*()" wrapper macros in the preceding commits. The rest aren't new, as we'd previously implicitly refer to "the_repository", but it's now more obvious that we were doing the wrong thing all along, and should have used the parameter instead. The change to change "get_index_format_default(the_repository)" in "read-cache.c" to use the "r" variable instead should arguably have been part of [1], or in the subsequent cleanup in [2]. Let's do it here, as can be seen from the initial code in [3] it's not important that we use "the_repository" there, but would prefer to always use the current repository. This change excludes the "the_repository" use in "upload-pack.c"'s upload_pack_advertise(), as the in-flight [4] makes that change. 1. ee1f0c242ef (read-cache: add index.skipHash config option, 2023-01-06) 2. 6269f8eaad0 (treewide: always have a valid "index_state.repo" member, 2023-01-17) 3. 7211b9e7534 (repo-settings: consolidate some config settings, 2019-08-13) 4.
