2018-05-22commit-graph: always load commit-graph informationDerrick Stolee
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()Derrick Stolee
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 commitDerrick Stolee
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 commitNguyễn Thái Ngọc Duy
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].

2018-04-26commit: Let the callback of for_each_mergetag return on errorJohannes Schindelin
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 commitsDerrick Stolee
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. There was no measureable performance change as a result of this patch. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-04-11commit: create get_commit_tree() methodDerrick Stolee
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_treeDerrick Stolee
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 parsingDerrick Stolee
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>

Convert lookup_commit, lookup_commit_or_die, lookup_commit_reference, and lookup_commit_reference_gently to take struct object_id arguments. Introduce a temporary in parse_object buffer in order to convert this function. This is required since in order to convert parse_object and parse_object_buffer, lookup_commit_reference_gently and lookup_commit_or_die would need to be converted. Not introducing a temporary would therefore require that lookup_commit_or_die take a struct object_id *, but lookup_commit would take unsigned char *, leaving a confusing and hard-to-use interface. parse_object_buffer will lose this temporary in a later patch.

2017-04-27timestamp_t: a new data type for timestampsJohannes Schindelin
Git's source code assumes that unsigned long is at least as precise as time_t. Which is incorrect, and causes a lot of problems, in particular where unsigned long is only 32-bit (notably on Windows, even in 64-bit versions). So let's just use a more appropriate data type instead. In preparation for this, we introduce the new `timestamp_t` data type. By necessity, this is a very, very large patch, as it has to replace all timestamps' data type in one go. As we will use a data type that is not necessarily identical to `time_t`, we need to be very careful to use `time_t` whenever we interact with the system functions, and `timestamp_t` everywhere else.

When "git merge-recursive" works on history with many criss-cross merges in "verbose" mode, the names the command assigns to the virtual merge bases could have overwritten each other by unintended reuse of the same piece of memory. * rs/pull-signed-tag: commit: use FLEX_ARRAY in struct merge_remote_desc merge-recursive: fix verbose output for multiple base trees commit: factor out set_merge_remote_desc() commit: use xstrdup() in get_merge_parent()
2016-08-14commit: use FLEX_ARRAY in struct merge_remote_descRené Scharfe
Convert the name member of struct merge_remote_desc to a FLEX_ARRAY and use FLEX_ALLOC_STR to build the struct. This halves the number of memory allocations, saves the storage for a pointer and avoids an indirection when reading the name.

2016-07-28Merge branch 'js/find-commit-subject-ignore-leading-blanks' into maintJunio C Hamano
A helper function that takes the contents of a commit object and finds its subject line did not ignore leading blank lines, as is commonly done by other codepaths. Make it ignore leading blank lines to match. * js/find-commit-subject-ignore-leading-blanks: reset --hard: skip blank lines when reporting the commit subject sequencer: use skip_blank_lines() to find the commit subject commit -C: skip blank lines at the beginning of the message commit.c: make find_commit_subject() more robust pretty: make the skip_blank_lines() function public
2016-07-19Merge branch 'jk/printf-format'Junio C Hamano
Code clean-up to avoid using a variable string that compilers may feel untrustable as printf-style format given to write_file() helper function. * jk/printf-format: commit.c: remove print_commit_list() avoid using sha1_to_hex output as printf format walker: let walker_say take arbitrary formats
