2021-07-07speed up alt_odb_usable() with many alternatesLibravatar Eric Wong1-0/+2
With many alternates, the duplicate check in alt_odb_usable() wastes many cycles doing repeated fspathcmp() on every existing alternate. Use a khash to speed up lookups by odb->path. Since the kh_put_* API uses the supplied key without duplicating it, we also take advantage of it to replace both xstrdup() and strbuf_release() in link_alt_odb_entry() with strbuf_detach() to avoid the allocation and copy. In a test repository with 50K alternates and each of those 50K alternates having one alternate each (for a total of 100K total alternates); this speeds up lookup of a non-existent blob from over 16 minutes to roughly 2.7 seconds on my busy workstation. Note: all underlying git object directories were small and unpacked with only loose objects and no packs. Having to load packs increases times significantly.

2021-06-28object.h: add lookup_object_by_type() functionLibravatar Jeff King1-0/+18
In some cases it's useful for efficiency reasons to get the type of an object before deciding whether to parse it, but we still want an object struct. E.g., in reachable.c, bitmaps give us the type, but we just want to mark flags on each object. Likewise, we may loop over every object and only parse tags in order to peel them; checking the type first lets us avoid parsing the non-tags. But our lookup_blob(), etc, functions make getting an object struct annoying: we have to call the right function for every type. And we cannot just use the generic lookup_object(), because it only returns an already-seen object; it won't allocate a new object struct. Let's provide a function that dispatches to the correct lookup_* function based on a run-time type. In fact, reachable.c already has such a helper, so we'll just make that public. I did change the return type from "void *" to "struct object *". While the former is a clever way to avoid casting inside the function, it's less safe and less informative to people reading the function declaration. The next commit will add a new caller.

2021-04-13lookup_unknown_object(): take a repository argumentLibravatar Jeff King1-4/+3
All of the other lookup_foo() functions take a repository argument, but lookup_unknown_object() was never converted, and it uses the_repository internally. Let's fix that. We could leave a wrapper that uses the_repository, but there aren't that many calls, so we'll just convert them all. I looked briefly at each site to see if we had a repository struct (besides the_repository) we could pass, but none of them do (so this conversion to pass the_repository is a pure noop in each case, though it does take us one step closer to eventually getting rid of the_repository).

2021-01-11bundle: lost objects when removing duplicate pendingsLibravatar Jiang Xin1-4/+6
`git rev-list` will list one commit for the following command: $ git rev-list 'main^!' <tip-commit-of-main-branch> But providing the same rev-list args to `git bundle`, fail to create a bundle file. $ git bundle create - 'main^!' # v2 git bundle -<OID> <one-line-message> fatal: Refusing to create empty bundle. This is because when removing duplicate objects in function `object_array_remove_duplicates()`, one unique pending object which has the same name is deleted by mistake. The revision arg 'main^!' in the above example is parsed by `handle_revision_arg()`, and at lease two different objects will be appended to `revs.pending`, one points to the parent commit of the "main" branch, and the other points to the tip commit of the "main" branch. These two objects have the same name "main". Only one object is left with the name "main" after calling the function `object_array_remove_duplicates()`. And what's worse, when adding boundary commits into pending list, we use one-line commit message as names, and the arbitory names may surprise git-bundle. Only comparing objects themselves (".item") is also not good enough, because user may want to create a bundle with two identical objects but with different reference names, such as: "HEAD" and "refs/heads/main". Add new function `contains_object()` which compare both the address and the name of the object. Signed-off-by: Jiang Xin <zhiyou.jx@alibaba-inc.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

hashmap_free(), hashmap_free_entries(), and hashmap_free_() have existed for a while, but aren't necessarily the clearest names, especially with hashmap_partial_clear() being added to the mix and lazy-initialization now being supported.

14ba97f8 (alloc: allow arbitrary repositories for alloc functions, 2018-05-15) introduced parsed_object_pool->commit_count to keep count of commits per repository and was used to assign commit->index.

2020-01-17replace-object: make replace operations thread-safeLibravatar Matheus Tavares1-0/+2
replace-object functions are very close to being thread-safe: the only current racy section is the lazy initialization at prepare_replace_object(). The following patches will protect some object reading operations to be called threaded, but before that, replace functions must be protected. To do so, add a mutex to struct raw_object_store and acquire it before lazy initializing the replace_map. This won't cause any noticeable performance drop as the mutex will no longer be used after the replace_map is initialized. Later, when the replace functions are called in parallel, thread debuggers might point our use of the added replace_map_initialized flag as a data race. However, as this boolean variable is initialized as false and it's only updated once, there's no real harm. It's perfectly fine if the value is updated right after a thread read it in replace-map.h:lookup_replace_object() (there'll only be a performance penalty for the affected threads at that moment). We could cease the debugger warning protecting the variable reading at the said function. However, this would negatively affect performance for all threads calling it, at any time, so it's not really worthy since the warning doesn't represent a real problem. Instead, to make sure we don't get false positives (at ThreadSanitizer, at least) an entry for the respective function is added to .tsan-suppressions.

2019-12-03packfile.c: speed up loading lots of packfilesLibravatar Colin Stolley1-0/+3
When loading packfiles on start-up, we traverse the internal packfile list once per file to avoid reloading packfiles that have already been loaded. This check runs in quadratic time, so for poorly maintained repos with a large number of packfiles, it can be pretty slow. Add a hashmap containing the packfile names as we load them so that the average runtime cost of checking for already-loaded packs becomes constant. Add a perf test to p5303 to show speed-up. The existing p5303 test runtimes are dominated by other factors and do not show an appreciable speed-up. The new test in p5303 clearly exposes a speed-up in bad cases. In this test we create 10,000 packfiles and measure the start-up time of git rev-parse, which does little else besides load in the packs. Here are the numbers for the new p5303 test: Test HEAD^ HEAD --------------------------------------------------------------------- 5303.12: load 10,000 packs 1.03(0.92+0.10) 0.12(0.02+0.09) -88.3% Signed-off-by: Colin Stolley <cstolley@runbox.com> Helped-by: Jeff King <peff@peff.net> [jc: squashed the change to call hashmap in install_packed_git() by peff] Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-01-27object_as_type: initialize commit-graph-related fields of 'struct commit'Libravatar SZEDER Gábor1-2/+3
When the commit graph and generation numbers were introduced in commits 177722b344 (commit: integrate commit graph with commit parsing, 2018-04-10) and 83073cc994 (commit: add generation number to struct commit, 2018-04-25), they tried to make sure that the corresponding 'graph_pos' and 'generation' fields of 'struct commit' are initialized conservatively, as if the commit were not included in the commit-graph file. Alas, initializing those fields only in alloc_commit_node() missed the case when an object that happens to be a commit is first looked up via lookup_unknown_object(), and is then later converted to a 'struct commit' via the object_as_type() helper function (either calling it directly, or as part of a subsequent lookup_commit() call). Consequently, both of those fields incorrectly remain set to zero, which means e.g. that the commit is present in and is the first entry of the commit-graph file. This will result in wrong timestamp, parent and root tree hashes, if such a 'struct commit' instance is later filled from the commit-graph. Extract the initialization of 'struct commit's fields from alloc_commit_node() into a helper function, and call it from object_as_type() as well, to make sure that it properly initializes the two commit-graph-related fields, too. With this helper function it is hopefully less likely that any new fields added to 'struct commit' in the future would remain uninitialized. With this change alloc_commit_index() won't have any remaining callers outside of 'alloc.c', so mark it as static.

2018-11-13sha1-file: use an object_directory for the main object dirLibravatar Jeff King1-9/+10
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.

2018-11-13handle alternates paths the same as the main object dirLibravatar Jeff King1-1/+0
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.

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)".

2018-07-17commit-graph: store graph in struct object_storeLibravatar Jonathan Tan1-0/+5
Instead of storing commit graphs in static variables, store them in struct object_store. There are no changes to the signatures of existing functions - they all still only support the_repository, and support for other instances of struct repository will be added in a subsequent commit.

2018-06-29tag: add repository argument to parse_tag_bufferLibravatar Stefan Beller1-1/+1
Add a repository argument to allow the callers of parse_tag_buffer to be more specific about which repository to act on. This is a small mechanical change; it doesn't change the implementation to handle repositories other than the_repository yet. As with the previous commits, use a macro to catch callers passing a repository other than the_repository at compile time.
