Edward Thomson f0e693b1 2021-09-07T17:53:49 str: introduce `git_str` for internal, `git_buf` is external libgit2 has two distinct requirements that were previously solved by `git_buf`. We require: 1. A general purpose string class that provides a number of utility APIs for manipulating data (eg, concatenating, truncating, etc). 2. A structure that we can use to return strings to callers that they can take ownership of. By using a single class (`git_buf`) for both of these purposes, we have confused the API to the point that refactorings are difficult and reasoning about correctness is also difficult. Move the utility class `git_buf` to be called `git_str`: this represents its general purpose, as an internal string buffer class. The name also is an homage to Junio Hamano ("gitstr"). The public API remains `git_buf`, and has a much smaller footprint. It is generally only used as an "out" param with strict requirements that follow the documentation. (Exceptions exist for some legacy APIs to avoid breaking callers unnecessarily.) Utility functions exist to convert a user-specified `git_buf` to a `git_str` so that we can call internal functions, then converting it back again.
lhchavez 83862c83 2020-02-17T21:28:13 commit-graph: Add a way to write commit-graph files This change adds the git_commit_graph_writer_* functions to allow to write and create `commit-graph` files from `.idx`/`.pack` files or `git_revwalk`s. Part of: #5757
lhchavez 8d453f16 2021-07-27T13:00:31 Swap the order of the `git_graph_reachable_from_any` params len, array -> array, len
lhchavez ce5400cd 2021-01-06T06:26:09 graph: Create `git_graph_reachable_from_any()` This change introduces a new API function `git_graph_reachable_from_any()`, that answers the question whether a commit is reachable from any of the provided commits through following parent edges. This function can take advantage of optimizations provided by the existence of a `commit-graph` file, since it makes it faster to know whether, given two commits X and Y, X cannot possibly be an reachable from Y. Part of: #5757

lhchavez 25b75cd9 2021-03-10T07:06:15 commit-graph: Create `git_commit_graph` as an abstraction for the file This change does a medium-size refactor of the git_commit_graph_file and the interaction with the ODB. Now instead of the ODB owning a direct reference to the git_commit_graph_file, there will be an intermediate git_commit_graph. The main advantage of that is that now end users can explicitly set a git_commit_graph that is eagerly checked for errors, while still being able to lazily use the commit-graph in a regular ODB, if the file is present.
lhchavez 1a2f9609 2021-01-05T06:24:26 commit-graph: Introduce `git_commit_graph_needs_refresh()` This change introduces a function that allows the caller to know whether the `commit-graph` file has not been modified since it was parsed. Part of: #5757
lhchavez 1f32ed25 2021-01-04T19:33:48 commit-graph: Support lookups of entries in a commit-graph This change introduces `git_commit_graph_entry_find()` and `git_commit_graph_entry_parent()`. These two functions allow a much faster lookup of commits by ID, since the ODB does not need to be consulted, the commit object does not need to be inflated, and the contents of the commit object do not need to be parsed. Part of: #5757
lhchavez 3fd57a75 2021-01-04T18:22:43 commit-graph: Introduce a parser for commit-graph files This change is the first in a series to add support for git's commit-graph. This should speed up commit graph traversals by avoiding object parsing and allowing some operations to terminate earlier. Part of: #5757
