The `ignore` crate currently handles two different kinds of "global" gitignore files: gitignores from `~/.gitconfig`'s `core.excludesFile` and gitignores passed in via `WalkBuilder::add_ignore` (corresponding to ripgrep's `--ignore-file` flag). In contrast to any other kind of gitignore file, these gitignore files should have their patterns interpreted relative to the current working directory. (Arguably there are other choices we could make here, e.g., based on the paths given. But the `ignore` infrastructure can't handle that, and it's not clearly correct to me.) Normally, a gitignore file has its patterns interpreted relative to where the gitignore file is. This relative interpretation matters for patterns like `/foo`, which are anchored to _some_ directory. Previously, we would generally get the global gitignores correct because it's most common to use ripgrep without providing a path. Thus, it searches the current working directory. In this case, no stripping of the paths is needed in order for the gitignore patterns to be applied directly. But if one provides an absolute path (or something else) to ripgrep to search, the paths aren't stripped correctly. Indeed, in the core, I had just given up and not provided a "root" path to these global gitignores. So it had no hope of getting this correct. We fix this assigning the CWD to the `Gitignore` values created from global gitignore files. This was a painful thing to do because we'd ideally: 1. Call `std::env::current_dir()` at most once for each traversal. 2. Provide a way to avoid the library calling `std::env::current_dir()` at all. (Since this is global process state and folks might want to set it to different values for $reasons.) The `ignore` crate's internals are a total mess. But I think I've addressed the above 2 points in a semver compatible manner. Fixes #3179 |
