2018-09-17Merge branch 'jk/trailer-fixes'Libravatar Junio C Hamano1-1/+1
"git interpret-trailers" and its underlying machinery had a buggy code that attempted to ignore patch text after commit log message, which triggered in various codepaths that will always get the log message alone and never get such an input. * jk/trailer-fixes: append_signoff: use size_t for string offsets sequencer: ignore "---" divider when parsing trailers pretty, ref-filter: format %(trailers) with no_divider option interpret-trailers: allow suppressing "---" divider interpret-trailers: tighten check for "---" patch boundary trailer: pass process_trailer_opts to trailer_info_get() trailer: use size_t for iterating trailer list trailer: use size_t for string offsets
2018-08-23append_signoff: use size_t for string offsetsLibravatar Jeff King1-1/+1
The append_signoff() function takes an "int" to specify the number of bytes to ignore. Most callers just pass 0, and the remainder use ignore_non_trailer() to skip over cruft. That function also returns an int, and uses them internally. On systems where size_t is larger than an int (i.e., most 64-bit systems), dealing with a ridiculously large commit message could end up overflowing an int, producing surprising results (e.g., returning a negative offset, which would cause us to look outside the original string). Let's consistently use size_t for these offsets through this whole stack. As a bonus, this makes the meaning of "ignore_footer" as an offset (and not a boolean) more clear. But while we're here, let's also document the interface. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2018-05-22commit-graph: always load commit-graph informationLibravatar Derrick Stolee1-1/+1
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.

2018-05-22commit: use generations in paint_down_to_common()Libravatar Derrick Stolee1-0/+1
Define compare_commits_by_gen_then_commit_date(), which uses generation numbers as a primary comparison and commit date to break ties (or as a comparison when both commits do not have computed generation numbers). Since the commit-graph file is closed under reachability, we know that all commits in the file have generation at most GENERATION_NUMBER_MAX which is less than GENERATION_NUMBER_INFINITY. This change does not affect the number of commits that are walked during the execution of paint_down_to_common(), only the order that those commits are inspected. In the case that commit dates violate topological order (i.e. a parent is "newer" than a child), the previous code could walk a commit twice: if a commit is reached with the PARENT1 bit, but later is re-visited with the PARENT2 bit, then that PARENT2 bit must be propagated to its parents. Using generation numbers avoids this extra effort, even if it is somewhat rare. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-05-22commit: add generation number to struct commitLibravatar Derrick Stolee1-0/+4
The generation number of a commit is defined recursively as follows: * If a commit A has no parents, then the generation number of A is one. * If a commit A has parents, then the generation number of A is one more than the maximum generation number among the parents of A. Add a uint32_t generation field to struct commit so we can pass this information to revision walks. We use three special values to signal the generation number is invalid: GENERATION_NUMBER_INFINITY 0xFFFFFFFF GENERATION_NUMBER_MAX 0x3FFFFFFF GENERATION_NUMBER_ZERO 0 The first (_INFINITY) means the generation number has not been loaded or computed. The second (_MAX) means the generation number is too large to store in the commit-graph file. The third (_ZERO) means the generation number was loaded from a commit graph file that was written by a version of git that did not support generation numbers.

2018-05-21commit.h: delete 'util' field in struct commitLibravatar Nguyễn Thái Ngọc Duy1-1/+5
If you have come this far, you probably have seen that this 'util' pointer is used for many different purposes. Some are not even contained in a command code, but buried deep in common code with no clue who will use it and how. The move to using commit-slab gives us a much better picture of how some piece of data is associated with a commit and what for. Since nobody uses 'util' pointer anymore, we can retire so that nobody will abuse it again. commit-slab will be the way forward for associating data to a commit. As a side benefit, this shrinks struct commit by 8 bytes (on 64-bit architecture) which should help reduce memory usage for reachability test a bit. This is also what commit-slab is invented for [1].

This is yet another patch to be filed under the keyword "libification". There is one subtle change in behavior here, where a `git log` that has been asked to show the mergetags would now stop reporting the mergetags upon the first failure, whereas previously, it would have continued to the next mergetag, if any. In practice, that change should not matter, as it is 1) uncommon to perform octopus merges using multiple tags as merge heads, and 2) when the user asks to be shown those tags, they really should be there.

2018-04-11commit-graph: lazy-load trees for commitsLibravatar Derrick Stolee1-0/+6
The commit-graph file provides quick access to commit data, including the OID of the root tree for each commit in the graph. When performing a deep commit-graph walk, we may not need to load most of the trees for these commits. Delay loading the tree object for a commit loaded from the graph until requested via get_commit_tree(). Do not lazy-load trees for commits not in the graph, since that requires duplicate parsing and the relative peformance improvement when trees are not needed is small. On the Linux repository, performance tests were run for the following command: git log --graph --oneline -1000 Before: 0.92s After: 0.66s Rel %: -28.3% Adding '-- kernel/' to the command requires loading the root tree for every commit that is walked.

2018-04-11commit: create get_commit_tree() methodLibravatar Derrick Stolee1-0/+3
While walking the commit graph, we load struct commit objects into the object cache. During this process, we also load struct tree objects for the root tree of each of these commits. We load these objects even if we are only computing commit reachability information, such as a merge base or ahead/behind information. Create get_commit_tree() as a first step to removing direct references to the 'maybe_tree' member of struct commit. Create get_commit_tree_oid() as a shortcut for several references to "&commit->maybe_tree->object.oid" in the codebase.

2018-04-11treewide: rename tree to maybe_treeLibravatar Derrick Stolee1-1/+1
Using the commit-graph file to walk commit history removes the large cost of parsing commits during the walk. This exposes a performance issue: lookup_tree() takes a large portion of the computation time, even when Git never uses those trees. In anticipation of lazy-loading these trees, rename the 'tree' member of struct commit to 'maybe_tree'. This serves two purposes: it hints at the future role of possibly being NULL even if the commit has a valid tree, and it allows for unambiguous transformation from simple member access (i.e. commit->maybe_tree) to method access.

2018-04-11commit: integrate commit graph with commit parsingLibravatar Derrick Stolee1-0/+3
Teach Git to inspect a commit graph file to supply the contents of a struct commit when calling parse_commit_gently(). This implementation satisfies all post-conditions on the struct commit, including loading parents, the root tree, and the commit date. If core.commitGraph is false, then do not check graph files. In test script t5318-commit-graph.sh, add output-matching conditions on read-only graph operations. By loading commits from the graph instead of parsing commit buffers, we save a lot of time on long commit walks. Here are some performance results for a copy of the Linux repository where 'master' has 678,653 reachable commits and is behind 'origin/master' by 59,929 commits. | Command | Before | After | Rel % | |----------------------------------|--------|--------|-------| | log --oneline --topo-order -1000 | 8.31s | 0.94s | -88% | | branch -vv | 1.02s | 0.14s | -86% | | rev-list --all | 5.89s | 1.07s | -81% | | rev-list --all --objects | 66.15s | 58.45s | -11% | Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Conversion from uchar[20] to struct object_id continues; this is to ensure that we do not assume sizeof(struct object_id) is the same as the length of SHA-1 hash (or length of longest hash we support). * po/read-graft-line: commit: rewrite read_graft_line commit: allocate array using object_id size commit: replace the raw buffer with strbuf in read_graft_line sha1_file: fix definition of null_sha1
