path: adjust last remaining users of `the_repository`

2025-02-28T21:54:11Z

With the preceding refactorings we now only have a couple of implicit users of `the_repository` left in the "path" subsystem, all of which depend on global state via `calc_shared_perm()`. Make the dependency on `the_repository` explicit by passing the repo as a parameter instead and adjust callers accordingly. Note that this change bubbles up into a couple of subsystems that were previously declared as free from `the_repository`. Instead of marking all of them as `the_repository`-dependent again, we instead use the repository that is available in the calling context. There are three exceptions though with "copy.c", "pack-write.c" and "tempfile.c". Adjusting these would require us to adapt callsites all over the place, so this is left for a future iteration. Mark "path.c" as free from `the_repository`. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

progress: stop using `the_repository`

2024-12-18T18:44:30Z

Stop using `the_repository` in the "progress" subsystem by passing in a repository when initializing `struct progress`. Furthermore, store a pointer to the repository in that struct so that we can pass it to the trace2 API when logging information. Adjust callers accordingly by using `the_repository`. While there may be some callers that have a repository available in their context, this trivial conversion allows for easier verification and bubbles up the use of `the_repository` by one level.

global: mark code units that generate warnings with `-Wsign-compare`

2024-12-06T11:20:02Z

Mark code units that generate warnings with `-Wsign-compare`. This allows for a structured approach to get rid of all such warnings over time in a way that can be easily measured. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

packfile: pass down repository to `for_each_packed_object`

2024-12-03T23:21:54Z

The function `for_each_packed_object` currently relies on the global variable `the_repository`. To eliminate global variable usage in `packfile.c`, we should progressively shift the dependency on the_repository to higher layers. Let's remove its usage from this function and closely related function `is_promisor_object`. Signed-off-by: Karthik Nayak Signed-off-by: Junio C Hamano

packfile: add repository to struct `packed_git`

2024-12-03T23:21:53Z

The struct `packed_git` holds information regarding a packed object file. Let's add the repository variable to this object, to represent the repository that this packfile belongs to. This helps remove dependency on the global `the_repository` object in `packfile.c` by simply using repository information now readily available in the struct. We do need to consider that a packfile could be part of the alternates of a repository, but considering that we only have one repository struct and also that we currently anyways use 'the_repository', we should be OK with this change. We also modify `alloc_packed_git` to ensure that the repository is added to newly created `packed_git` structs. This requires modifying the function and all its callee to pass the repository object down the levels. Helped-by: Taylor Blau Signed-off-by: Karthik Nayak Signed-off-by: Junio C Hamano

commit-graph: remove unnecessary UNLEAK

2024-09-23T17:03:59Z

When f4dbdfc4d5 (commit-graph: clean up leaked memory during write, 2018-10-03) added the UNLEAK, it was right before a call to die_errno(). e103f7276f (commit-graph: return with errors during write, 2019-06-12) made it unnecessary, as it was then followed by a free() call for the allocated string. The code moved to write_commit_graph_file() in the meantime and the string pointer is now part of a struct, but the function's only caller still cleans up the allocation. Drop the superfluous UNLEAK.

refs: add referent to each_ref_fn

2024-08-09T15:47:34Z

Add a parameter to each_ref_fn so that callers to the ref APIs that use this function as a callback can have acess to the unresolved value of a symbolic ref. Signed-off-by: John Cai Signed-off-by: Junio C Hamano
