2020-05-20t4216: avoid unnecessary subshell in test_bloom_filters_not_usedLibravatar Carlo Marcelo Arenas Belón1-1/+1
Seems to trigger a bug in at least OpenBSD's 6.7 sh where it is interpreted as a history lookup and therefore fails 125-126, 128, 130. Remove the subshell and get a space between ! and grep, so tests pass successfully. Signed-off-by: Carlo Marcelo Arenas Belón <carenas@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-04-09bloom: ignore renames when computing changed pathsLibravatar Derrick Stolee1-0/+1
The changed-path Bloom filters record an entry in the filter for every path that was changed. This includes every add and delete, regardless of whether a rename was detected. Detecting renames causes significant performance issues, but also will trigger downloading missing blobs in partial clone. The simple fix is to disable rename detection when computing a changed-path Bloom filter. This should already be disabled by default, but it is good to explicitly enforce the intended behavior.

Add GIT_TEST_COMMIT_GRAPH_CHANGED_PATHS test flag to the test setup suite in order to toggle writing Bloom filters when running any of the git tests. If set to true, we will compute and write Bloom filters every time a test calls `git commit-graph write`, as if the `--changed-paths` option was passed in. The test suite passes when GIT_TEST_COMMIT_GRAPH and GIT_TEST_COMMIT_GRAPH_CHANGED_PATHS are enabled.

2020-04-06t4216: add end to end tests for git log with Bloom filtersLibravatar Garima Singh2-0/+159
These tests exercises writing commit graph with Bloom filters and exercises 'git log -- path' with all the applicable options. They check that the output is the same with and without Bloom filters, confirm Bloom filters were used by checking if trace2 statistics were logged correctly. Also confirms cases where Bloom filters are not used: 1. Multiple path specs, 2. --walk-reflogs (see patch titled 'revision.c: use Bloom filters...' for details, 3.

2020-04-06revision.c: use Bloom filters to speed up path based revision walksLibravatar Garima Singh4-2/+118
Revision walk will now use Bloom filters for commits to speed up revision walks for a particular path (for computing history for that path), if they are present in the commit-graph file. We load the Bloom filters during the prepare_revision_walk step, currently only when dealing with a single pathspec. Extending it to work with multiple pathspecs can be explored and built on top of this series in the future. While comparing trees in rev_compare_trees(), if the Bloom filter says that the file is not different between the two trees, we don't need to compute the expensive diff. This is where we get our performance gains. The other response of the Bloom filter is '`:maybe', in which case we fall back to the full diff calculation to determine if the path was changed in the commit. We do not try to use Bloom filters when the '--walk-reflogs' option is specified. The '--walk-reflogs' option does not walk the commit ancestry chain like the rest of the options. Incorporating the performance gains when walking reflog entries would add more complexity, and can be explored in a later series. Performance Gains: We tested the performance of `git log -- <path>` on the git repo, the linux and some internal large repos, with a variety of paths of varying depths. On the git and linux repos: - we observed a 2x to 5x speed up. On a large internal repo with files seated 6-10 levels deep in the tree: - we observed 10x to 20x speed ups, with some paths going up to 28 times faster.

Add --changed-paths option to git commit-graph write. This option will allow users to compute information about the paths that have changed between a commit and its first parent, and write it into the commit graph file.

2020-04-06commit-graph: reuse existing Bloom filters during writeLibravatar Garima Singh4-6/+55
Add logic to a) parse Bloom filter information from the commit graph file and, b) re-use existing Bloom filters. See Documentation/technical/commit-graph-format for the format in which the Bloom filter information is written to the commit graph file. To read Bloom filter for a given commit with lexicographic position 'i' we need to: 1. Read BIDX[i] which essentially gives us the starting index in BDAT for filter of commit i+1. It is essentially the index past the end of the filter of commit i. It is called end_index in the code. 2. For i>0, read BIDX[i-1] which will give us the starting index in BDAT for filter of commit i. It is called the start_index in the code. For the first commit, where i = 0, Bloom filter data starts at the beginning, just past the header in the BDAT chunk. Hence, start_index will be 0. 3. The length of the filter will be end_index - start_index, because BIDX[i] gives the cumulative 8-byte words including the ith commit's filter. We toggle whether Bloom filters should be recomputed based on the compute_if_not_present flag.

2020-03-30commit-graph: examine commits by generation numberLibravatar Garima Singh1-3/+30
When running 'git commit-graph write --changed-paths', we sort the commits by pack-order to save time when computing the changed-paths bloom filters. This does not help when finding the commits via the '--reachable' flag. If not using pack-order, then sort by generation number before examining the diff. Commits with similar generation are more likely to have many trees in common, making the diff faster. On the Linux kernel repository, this change reduced the computation time for 'git commit-graph write --reachable --changed-paths' from 3m00s to 1m37s.

2020-03-30commit-graph: examine changed-path objects in pack orderLibravatar Jeff King1-3/+35
Looking at the diff of commit objects in pack order is much faster than in sha1 order, as it gives locality to the access of tree deltas (whereas sha1 order is effectively random). Unfortunately the commit-graph code sorts the commits (several times, sometimes as an oid and sometimes a pointer-to-commit), and we ultimately traverse in sha1 order. Instead, let's remember the position at which we see each commit, and traverse in that order when looking at bloom filters. This drops my time for "git commit-graph write --changed-paths" in linux.git from ~4 minutes to ~1.5 minutes. Probably the "--reachable" code path would want something similar. Or alternatively, we could use a different data structure (either a hash, or maybe even just a bit in "struct commit") to keep track of which oids we've seen, etc instead of sorting. And then we could keep the original order. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Garima Singh <garima.singh@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-03-30diff: halt tree-diff early after max_changesLibravatar Derrick Stolee3-1/+14
When computing the changed-paths bloom filters for the commit-graph, we limit the size of the filter by restricting the number of paths in the diff. Instead of computing a large diff and then ignoring the result, it is better to halt the diff computation early. Create a new "max_changes" option in struct diff_options. If non-zero, then halt the diff computation after discovering strictly more changed paths. This includes paths corresponding to trees that change. Use this max_changes option in the bloom filter calculations. This reduces the time taken to compute the filters for the Linux kernel repo from 2m50s to 2m35s. On a large internal repository with ~500 commits that perform tree-wide changes, the time reduced from 6m15s to 3m48s.

2020-03-30bloom.c: core Bloom filter implementation for changed paths.Libravatar Garima Singh4-0/+172
Add the core implementation for computing Bloom filters for the paths changed between a commit and it's first parent. We fill the Bloom filters as (const char *data, int len) pairs as `struct bloom_filters" within a commit slab. Filters for commits with no changes and more than 512 changes, is represented with a filter of length zero. There is no gain in distinguishing between a computed filter of length zero for a commit with no changes, and an uncomputed filter for new commits or for commits with more than 512 changes. The effect on `git log -- path` is the same in both cases. We will fall back to the normal diffing algorithm when we can't benefit from the existence of Bloom filters.

2020-03-30bloom.c: introduce core Bloom filter constructsLibravatar Garima Singh4-1/+188
Introduce the constructs for Bloom filters, Bloom filter keys and Bloom filter settings. For details on what Bloom filters are and how they work, refer to Dr. Derrick Stolee's blog post [1]. It provides a concise explanation of the adoption of Bloom filters as described in [2] and [3]. Implementation specifics: 1. We currently use 7 and 10 for the number of hashes and the size of each entry respectively. They served as great starting values, the mathematical details behind this choice are described in [1] and [4]. The implementation, while not completely open to it at the moment, is flexible enough to allow for tweaking these settings in the future. Note: The performance gains we have observed with these values are significant enough that we did not need to tweak these settings. The performance numbers are included in the cover letter of this series and in the commit message of the subsequent commit where we use Bloom filters to speed up `git log -- path`. 2. As described in [1] and [3], we do not need 7 independent hashing functions. We use the Murmur3 hashing scheme, seed it twice and then combine those to procure an arbitrary number of hash values. 3. The filters will be sized according to the number of changes in each commit, in multiples of 8 bit words.

2020-03-20pack-objects: flip the use of GIT_TEST_PACK_SPARSELibravatar Derrick Stolee3-5/+6
The environment variable GIT_TEST_PACK_SPARSE was previously used to allow testing the --sparse option for "git pack-objects" in the test suite. This allowed interesting cases of "git push" to also test this algorithm. Since pack.useSparse is now true by default, we do not need this variable to _enable_ the --sparse option, but instead to _disable_ it. This flips how we work with the variable a bit. When checking for the variable, default to a value of -1 for "unset". If unset, then take the default from the repo settings, which is currently 1. Then, the --[no-]sparse command-line option will override either of these settings. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-03-20config: set pack.useSparse=true by defaultLibravatar Derrick Stolee5-11/+12
The pack.useSparse config option was introduced by 3d036eb0 (pack-objects: create pack.useSparse setting, 2019-01-19) and was first available in v2.21.0. When enabled, the pack-objects process during 'git push' will use a sparse tree walk when deciding which trees and blobs to send to the remote. The algorithm was introduced by d5d2e93 (revision: implement sparse algorithm, 2019-01-16) and has been in production use by VFS for Git since around that time. The features.experimental config option also enabled pack.useSparse, so hopefully that has also increased exposure. It is worth noting that pack.useSparse has a possibility of sending more objects across a push, but requires a special arrangement of exact _copies_ across directories. There is a test in t5322-pack-objects-sparse.sh that demonstrates this possibility. This test uses the --sparse option to "git pack-objects" but we can make it implied by the config value to demonstrate that the default value has changed. While updating that test, I noticed that the documentation did not include an option for --no-sparse, which is now more important than it was before. Since the downside is unlikely but the upside is significant, set the default value of pack.useSparse to true. Remove it from the set of options implied by features.experimental.
