Bryan Boreham	82a8c6abe2	[ENHANCEMENT] Optimize regexps with multiple prefixes (#13843 ) For example `foo.\|bar.\|baz.`. Instead of checking each one in turn, we build a map of prefixes, then check the smaller set that could match the string supplied.

Oleg Zaytsev	bcff5059e6	Use utf8.DecodeRuneInString(s) This replaces the custom `moreThanOneRune` function with the standard `utf8.DecodeRuneInString(s)` that can be used to figure out the size of the first rune. Signed-off-by: Oleg Zaytsev <mail@olegzaytsev.com>	7 months ago
Oleg Zaytsev	2524a91591	Fix FastRegexMatcher matching multibyte runes with . (#14059 ) When `zeroOrOneCharacterStringMatcher` wach checking the input string, it assumed that if there are more than one bytes, then there are more than one runes, but that's not necessarily true.

Bryan Boreham	579331446a	Allow downstream projects to use faster regexp (#10251 ) * Add benchmark for FastRegexMatcher Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Use modified regexp package with optimisations See https://github.com/grafana/regexp/tree/speedup#readme Includes the following changes proposed upstream: * [regexp: allow patterns with no alternates to be one-pass](https://go-review.googlesource.com/c/go/+/353711) * [regexp: speed up onepass prefix check](https://go-review.googlesource.com/c/go/+/354909) * [regexp: handle prefix string with fold-case](https://go-review.googlesource.com/c/go/+/358756) * [regexp: avoid copying each instruction executed](https://go-review.googlesource.com/c/go/+/355789) * [regexp: allow prefix string anchored at beginning](https://go-review.googlesource.com/c/go/+/377294) Signed-off-by: Bryan Boreham <bjboreham@gmail.com> * Use regexp code identical to upstream Go Change `grafana/regexp` import to use `main` branch. This means Prometheus is not using the proposed optimisations, but downstream users of Prometheus code are able to `replace` the library with the `speedup` branch which does.
