hash-ll.h: split out of hash.h to remove dependency on repository.h

2023-04-24T19:47:32Z

hash.h depends upon and includes repository.h, due to the definition and use of the_hash_algo (defined as the_repository->hash_algo). However, most headers trying to include hash.h are only interested in the layout of the structs like object_id. Move the parts of hash.h that do not depend upon repository.h into a new file hash-ll.h (the "low level" parts of hash.h), and adjust other files to use this new header where the convenience inline functions aren't needed. This allows hash.h and object.h to be fairly small, minimal headers. It also exposes a lot of hidden dependencies on both path.h (which was brought in by repository.h) and repository.h (which was previously implicitly brought in by object.h), so also adjust other files to be more explicit about what they depend upon.

treewide: be explicit about dependence on gettext.h

2023-03-21T17:56:51Z

Dozens of files made use of gettext functions, without explicitly including gettext.h. This made it more difficult to find which files could remove a dependence on cache.h. Make C files explicitly include gettext.h if they are using it. However, while compat/fsmonitor/fsm-ipc-darwin.c should also gain an include of gettext.h, it was left out to avoid conflicting with an in-flight topic.

alloc.h: move ALLOC_GROW() functions from cache.h

2023-02-24T01:25:28Z

This allows us to replace includes of cache.h with includes of the much smaller alloc.h in many places. It does mean that we also need to add includes of alloc.h in a number of C files. Signed-off-by: Elijah Newren Signed-off-by: Junio C Hamano

checkout: fix two bugs on the final count of updated entries

2022-07-14T17:19:28Z

At the end of `git checkout `, we get a message informing how many entries were updated in the working tree. However, this number can be inaccurate for two reasons: 1) Delayed entries currently get counted twice. 2) Failed entries are included in the count. The first problem happens because the counter is first incremented before inserting the entry in the delayed checkout queue, and once again when finish_delayed_checkout() calls checkout_entry(). And the second happens because the counter is incremented too early in checkout_entry(), before the entry was in fact checked out. Fix that by moving the count increment further down in the call stack and removing the duplicate increment on delayed entries. Note that we have to keep a per-entry reference for the counter (both on parallel checkout and delayed checkout) because not all entries are always accumulated at the same counter. See checkout_worktree(), at builtin/checkout.c for an example. Signed-off-by: Matheus Tavares Signed-off-by: Junio C Hamano

odb: teach read_blob_entry to use size_t

2021-11-03T18:22:27Z

There is mixed use of size_t and unsigned long to deal with sizes in the codebase. Recall that Windows defines unsigned long as 32 bits even on 64-bit platforms, meaning that converting size_t to unsigned long narrows the range. This mostly doesn't cause a problem since Git rarely deals with files larger than 2^32 bytes. But adjunct systems such as Git LFS, which use smudge/clean filters to keep huge files out of the repository, may have huge file contents passed through some of the functions in entry.c and convert.c. On Windows, this results in a truncated file being written to the workdir. I traced this to one specific use of unsigned long in write_entry (and a similar instance in write_pc_item_to_fd for parallel checkout). That appeared to be for the call to read_blob_entry, which expects a pointer to unsigned long. By altering the signature of read_blob_entry to expect a size_t, write_entry can be switched to use size_t internally (which all of its callers and most of its callees already used). To avoid touching dozens of additional files, read_blob_entry uses a local unsigned long to call a chain of functions which aren't prepared to accept size_t.
