environment: stop storing `core.attributesFile` globally

2026-02-17T20:09:42Z

The `core.attributeFile` config value is parsed in git_default_core_config(), loaded eagerly and stored in the global variable `git_attributes_file`. Storing this value in a global variable can lead to it being overwritten by another repository when more than one Git repository run in the same Git process. Create a new struct `repo_config_values` to hold this value and other repository dependent values parsed by `git_default_config()`. This will ensure the current behaviour remains the same while also enabling the libification of Git. An accessor function 'repo_config_values()' s created to ensure that we do not access an uninitialized repository, or an instance of a different repository than the current one.

commit-graph: refactor `parse_commit_graph()` to take a repository

2025-08-15T16:34:47Z

Refactor `parse_commit_graph()` so that it takes a repository instead of taking repository settings. On the one hand this allows us to get rid of instances where we access `the_hash_algo` by using the repository's hash algorithm instead. On the other hand it also allows us to move the call of `prepare_repo_settings()` into the function itself. Note that there's one small catch, as the commit-graph fuzzer calls this function directly without having a fully functional repository at hand. And while the fuzzer already initializes `the_repository` with relevant info, the call to `prepare_repo_settings()` would fail because we don't have a fully-initialized repository. Work around the issue by also settings `settings.initialized` to pretend that we've already read the settings. While at it, remove the redundant `parse_commit_graph()` declaration in the fuzzer. It was added together with aa658574bf (commit-graph, fuzz: add fuzzer for commit-graph, 2019-01-15), but as we also declared the same function in "commit-graph.h" it wasn't ever needed.

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-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

meson: simplify use of the common-main library

2025-02-26T17:09:35Z

The "common-main.c" file is used by multiple executables. In order to make it easy to set it up we have created a separate library that these executables can link against. All of these executables also want to link against `libgit.a` though, which makes it necessary to specify both of these as dependencies for every executable. Simplify this a bit by declaring the library as a source dependency: instead of creating a static library, we now instead compile the common set of files into each executable separately.

meson: wire up fuzzers

2025-01-22T20:37:33Z

Meson does not yet know to build our fuzzers. Introduce a new build option "fuzzers" and wire up the fuzzers in case it is enabled. Adapt our CI jobs so that they build the fuzzers by default. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano
