2020-06-23commit-reach: avoid is_descendant_of() shimCarlo Marcelo Arenas Belón
d91d6fbf26 (commit-reach: create repo_is_descendant_of(), 2020-06-17) adds a repository aware version of is_descendant_of() and a backward compatibility shim that is barely used. Update all callers to directly use the new repo_is_descendant_of() function instead; making the codebase simpler and pushing more the_repository references higher up the stack.

2020-06-17object: drop parsed_object_pool->commit_countAbhishek Kumar
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. However, commit-slab code requires commit->index values to be unique and a global count would be correct, rather than a per-repo count. Let's introduce a static counter variable, `parsed_commits_count` to keep track of parsed commits so far. As commit_count has no use anymore, let's also drop it from the struct.

2020-05-18t/helper: teach test-regex to report pattern errors (like REG_ILLSEQ)Carlo Marcelo Arenas Belón
7187c7bbb8 (t4210: skip i18n tests that don't work on FreeBSD, 2019-11-27) adds a REG_ILLSEQ prerequisite to avoid failures from the tests added in 4e2443b181 (log tests: test regex backends in "--encode=<enc>" tests, 2019-06-28), but hardcodes it to be only enabled in FreeBSD. Instead of hardcoding the affected platform, teach the test-regex helper, how to validate a pattern and report back, so it can be used to detect the same issue in other affected systems (like DragonFlyBSD or macOS). While at it, refactor the tool so it can report back the source of the errors it founds, and can be invoked also in a --silent mode, when needed, for backward compatibility. A missing flag has been added and the code reformatted, as well as updates to the way the parameters are handled, for consistency. To minimize changes, it is assumed the regcomp error is of the right type since we control the only caller, and is also assumed to affect both basic and extended syntax (only basic is tested, but both behave the same in all three affected platforms since they use the same function).

However, 'load_commit_graph_one' does not support commit-graph chains, and hence the 'read-graph' test tool does not work with them. Replace 'load_commit_graph_one' with 'read_commit_graph_one' in order to support commit-graph chains.

2020-04-06commit-graph: reuse existing Bloom filters during writeGarima Singh
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.

We renamed the actual data structure in 910650d2f8 (Rename sha1_array to oid_array, 2017-03-31), but the file is still called sha1-array. Besides being slightly confusing, it makes it more annoying to grep for leftover occurrences of "sha1" in various files, because the header is included in so many places. Let's complete the transition by renaming the source and header files (and fixing up a few comment references). I kept the "-" in the name, as that seems to be our style; cf. fc1395f4a4 (sha1_file.c: rename to use dash in file name, 2018-04-10). We also have oidmap.h and oidset.h without any punctuation, but those are "struct oidmap" and "struct oidset" in the code. We _could_ make this "oidarray" to match, but somehow it looks uglier to me because of the length of "array" (plus it would be a very invasive patch for little gain).

2020-03-30bloom.c: core Bloom filter implementation for changed paths.Garima Singh
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 constructsGarima Singh
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.

Returning a shared buffer invites very subtle bugs due to reentrancy or multi-threading, as demonstrated by the previous patch. There was an unfinished effort to abolish this [1]. Let's finally rid of `real_path()`, using `strbuf_realpath()` instead. This patch uses a local `strbuf` for most places where `real_path()` was previously called. However, two places return the value of `real_path()` to the caller. For them, a `static` local `strbuf` was added, effectively pushing the problem one level higher: read_gitfile_gently() get_superproject_working_tree() [1] https://lore.kernel.org/git/1480964316-99305-1-git-send-email-bmwill@google.com/ Signed-off-by: Alexandr Miloslavskiy <alexandr.miloslavskiy@syntevo.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Add a new helper advise_enabled to check the visibility of the advice if the caller needs to carry out complicated processing based on that value.

2020-02-24t/helper/test-dump-split-index: initialize git repositorybrian m. carlson
In this test helper, we read the index. In order to have the proper hash algorithm set up, we must call setup_git_directory. Do so, so that the test works when extensions.objectFormat is set.

2020-02-24use strpbrk(3) to search for characters from a given setRené Scharfe
We can check if certain characters are present in a string by calling strchr(3) on each of them, or we can pass them all to a single strpbrk(3) call.
