hash: require hash algorithm in `oidread()` and `oidclr()`

2024-06-14T17:26:32Z

Both `oidread()` and `oidclr()` use `the_repository` to derive the hash function that shall be used. Require callers to pass in the hash algorithm to get rid of this implicit dependency. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

hash: require hash algorithm in `hasheq()`, `hashcmp()` and `hashclr()`

2024-06-14T17:26:32Z

Many of our hash functions have two variants, one receiving a `struct git_hash_algo` and one that derives it via `the_repository`. Adapt all of those functions to always require the hash algorithm as input and drop the variants that do not accept one. As those functions are now independent of `the_repository`, we can move them from "hash.h" to "hash-ll.h". Note that both in this and subsequent commits in this series we always just pass `the_repository->hash_algo` as input even if it is obvious that there is a repository in the context that we should be using the hash from instead. This is done to be on the safe side and not introduce any regressions. All callsites should eventually be amended to use a repo passed via parameters, but this is outside the scope of this patch series. Signed-off-by: Patrick Steinhardt Signed-off-by: Junio C Hamano

unpack: replace xwrite() loop with write_in_full()

2024-03-02T19:12:16Z

We have two packfile stream consumers, index-pack and unpack-objects, that allow excess payload after the packfile stream data. Their code to relay excess data hasn't changed significantly since their original implementation that appeared in 67e5a5ec (git-unpack-objects: re-write to read from stdin, 2005-06-28) and 9bee2478 (mimic unpack-objects when --stdin is used with index-pack, 2006-10-25). These code blocks contain hand-rolled loops using xwrite(), written before our write_in_full() helper existed. This helper now provides the same functionality. Replace these loops with write_in_full() for shorter, clearer code. Update related variables accordingly. Signed-off-by: Junio C Hamano

treewide: remove unnecessary includes in source files

2023-12-26T20:04:31Z

Each of these were checked with gcc -E -I. ${SOURCE_FILE} | grep ${HEADER_FILE} to ensure that removing the direct inclusion of the header actually resulted in that header no longer being included at all (i.e. that no other header pulled it in transitively). ...except for a few cases where we verified that although the header was brought in transitively, nothing from it was directly used in that source file. These cases were: * builtin/credential-cache.c * builtin/pull.c * builtin/send-pack.c Signed-off-by: Elijah Newren Signed-off-by: Junio C Hamano

treewide: fix various bugs w/ OpenSSL 3+ EVP API

2023-09-01T05:26:01Z

The OpenSSL 3+ EVP API for SHA-* cannot support our prior use cases supported by other SHA-* implementations. It has the following differences: 1. ->init_fn is required before all use 2. struct assignments don't work and requires ->clone_fn 3. can't support ->update_fn after ->final_*fn While fixing cases 1 and 2 is merely the matter of calling ->init_fn and ->clone_fn as appropriate, fixing case 3 requires calling ->final_*fn on a temporary context that's cloned from the primary context.

fsck: mark unused parameters in various fsck callbacks

2023-07-14T00:24:00Z

There are a few callback functions which are used with the fsck code, but it's natural that not all callbacks need all parameters. For reporting, even something as obvious as "the oid of the object which had a problem" is not always used, as some callers are only checking a single object in the first place. And for both reporting and walking, things like void data pointers and the fsck_options aren't always necessary. But since each such parameter is used by _some_ callback, we have to keep them in the interface. Mark the unused ones in specific callbacks to avoid triggering -Wunused-parameter.

git-compat-util: move strbuf.c funcs to its header

2023-07-05T18:41:18Z

While functions like starts_with() probably should not belong in the boundaries of the strbuf library, this commit focuses on first splitting out headers from git-compat-util.h. Signed-off-by: Calvin Wan Signed-off-by: Junio C Hamano
