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.
