The bug fix was in expression pretty printing. ripgrep parses the regex
into an AST and may do some modifications to it, which requires the
ability to go from string -> AST -> string' -> AST' where string == string'
implies AST == AST'.
Also, add a regression test for the specific regex that tripped the bug.
Fixes#156.
This commit completes the initial move of glob matching to an external
crate, including fixing up cross platform support, polishing the
external crate for others to use and fixing a number of bugs in the
process.
Fixes#87, #127, #131
This commit goes a long way toward refactoring glob sets so that the
code is easier to maintain going forward. In particular, it makes the
literal optimizations that glob sets used a lot more structured and much
easier to extend. Tests have also been modified to include glob sets.
There's still a bit of polish work left to do before a release.
This also fixes the immediate issue where large gitignore files were
causing ripgrep to slow way down. While we don't technically fix it for
good, we're a lot better about reducing the number of regexes we
compile. In particular, if a gitignore file contains thousands of
patterns that can't be matched more simply using literals, then ripgrep
will slow down again. We could fix this for good by avoiding RegexSet if
the number of regexes grows too large.
Fixes#134.
This helps #134 by avoiding a slow regex execution path, but doesn't
actually fix the problem. Namely, we've gone from "so slow I'm not going
to keep waiting for rg to finish" to "wow that was slow but at least it
finished before I lost my patience."
It didn't make sense for --quiet to be part of the printer, because --quiet
doesn't just mean "don't print," it also means, "stop after the first
match is found." This needs to be wired all the way up through directory
traversal, and it also needs to cause all of the search workers to quit
as well. We do it with an atomic that is only checked with --quiet is
given.
Fixes#116.
