To future-proof ourselves against a change in the hash, let's use the more generic "hash mismatch" to refer to integrity problems. Note that we do advertise this exact string in git-fsck(1). However, the message itself is marked for translation, meaning we do not expect it to be machine-readable. While we're touching that documentation, let's also update it for grammar and clarity.

Our handling of alternate object directories is needlessly different from the main object directory. As a result, many places in the code basically look like this: do_something(r->objects->objdir); for (odb = r->objects->alt_odb_list; odb; odb = odb->next) do_something(odb->path); That gets annoying when do_something() is non-trivial, and we've resorted to gross hacks like creating fake alternates (see find_short_object_filename()). Instead, let's give each raw_object_store a unified list of object_directory structs. The first will be the main store, and everything after is an alternate. Very few callers even care about the distinction, and can just loop over the whole list (and those who care can just treat the first element differently). A few observations: - we don't need r->objects->objectdir anymore, and can just mechanically convert that to r->objects->odb->path - object_directory's path field needs to become a real pointer rather than a FLEX_ARRAY, in order to fill it with expand_base_dir() - we'll call prepare_alt_odb() earlier in many functions (i.e., outside of the loop). This may result in us calling it even when our function would be satisfied looking only at the main odb. But this doesn't matter in practice. It's not a very expensive operation in the first place, and in the majority of cases it will be a noop. We call it already (and cache its results) in prepare_packed_git(), and we'll generally check packs before loose objects. So essentially every program is going to call it immediately once per program. Arguably we should just prepare_alt_odb() immediately upon setting up the repository's object directory, which would save us sprinkling calls throughout the code base (and forgetting to do so has been a source of subtle bugs in the past). But I've stopped short of that here, since there are already a lot of other moving parts in this patch. - Most call sites just get shorter. The check_and_freshen() functions are an exception, because they have entry points to handle local and nonlocal directories separately.

When we generate loose file paths for the main object directory, the caller provides a buffer to loose_object_path (formerly sha1_file_name). The callers generally keep their own static buffer to avoid excessive reallocations. But for alternate directories, each struct carries its own scratch buffer. This is needlessly different; let's unify them. We could go either direction here, but this patch moves the alternates struct over to the main directory style (rather than vice-versa). Technically the alternates style is more efficient, as it avoids rewriting the object directory name on each call. But this is unlikely to matter in practice, as we avoid reallocations either way (and nobody has ever noticed or complained that the main object directory is copying a few extra bytes before making a much more expensive system call). And this has the advantage that the reusable buffers are tied to particular calls, which makes the invalidation rules simpler (for example, the return value from stat_sha1_file() used to be invalidated by basically any other object call, but now it is affected only by other calls to stat_sha1_file()). We do steal the trick from alt_sha1_path() of returning a pointer to the filled buffer, which makes a few conversions more convenient.

In preparation for unifying the handling of alt odb's and the normal repo object directory, let's use a more neutral name. This patch is purely mechanical, swapping the type name, and converting any variables named "alt" to "odb". There should be no functional change, but it will reduce the noise in subsequent diffs.

This is the partner patch to the previous one, but covering the "hash" variants instead of "oid". Note that our coccinelle rule is slightly more complex to avoid triggering the call in hasheq(). I didn't bother to add a new rule to convert: - hasheq(E1->hash, E2->hash) + oideq(E1, E2) Since these are new functions, there won't be any such existing callers. And since most of the code is already using oideq, we're not likely to introduce new ones. We might still see "!hashcmp(E1->hash, E2->hash)" from topics in flight. But because our new rule comes after the existing ones, that should first get converted to "!oidcmp(E1, E2)" and then to "oideq(E1, E2)".

Most code paths load commits using lookup_commit() and then parse_commit(). In some cases, including some branch lookups, the commit is parsed using parse_object_buffer() which side-steps parse_commit() in favor of parse_commit_buffer(). With generation numbers in the commit-graph, we need to ensure that any commit that exists in the commit-graph file has its generation number loaded. Create new load_commit_graph_info() method to fill in the information for a commit that exists only in the commit-graph file. Call it from parse_commit_buffer() after loading the other commit information from the given buffer. Only fill this information when specified by the 'check_graph' parameter.

This should make these functions easier to find and cache.h less overwhelming to read. In particular, this moves: - read_object_file - oid_object_info - write_object_file As a result, most of the codebase needs to #include object-store.h. In this patch the #include is only added to files that would fail to compile otherwise. It would be better to #include wherever identifiers from the header are used. That can happen later when we have better tooling for it. Signed-off-by: NStefan Beller <sbeller@google.com> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

We have to convert all of the alloc functions at once, because alloc_report uses a funky macro for reporting. It is better for the sake of mechanical conversion to convert multiple functions at once rather than changing the structure of the reporting function. We record all memory allocation in alloc.c, and free them in clear_alloc_state, which is called for all repositories except the_repository.

Convert the existing global cache for parsed objects (obj_hash) into repository-specific parsed object caches. Existing code that uses obj_hash are modified to use the parsed object cache of the_repository; future patches will use the parsed object caches of other repositories. Another future use case for a pool of objects is ease of memory management in revision walking: If we can free the rev-list related memory early in pack-objects (e.g. part of repack operation) then it could lower memory pressure significantly when running on large repos. While this has been discussed on the mailing list lately, this series doesn't implement this. Signed-off-by: NStefan Beller <sbeller@google.com> Signed-off-by: NJunio C Hamano <gitster@pobox.com>
