Ingo Oeser 9aed16e96d regexp: avoid alloc in QuoteMeta when not quoting ... Many users quote literals in regular expressions just in case. No need to allocate then. Note: Also added benchmarks for quoting and not quoting. name old time/op new time/op delta QuoteMetaAll-4 629ns ± 6% 654ns ± 5% +4.01% (p=0.001 n=20+19) QuoteMetaNone-4 1.02µs ± 6% 0.20µs ± 0% -80.73% (p=0.000 n=18+20) name old speed new speed delta QuoteMetaAll-4 22.3MB/s ± 6% 21.4MB/s ± 5% -3.94% (p=0.001 n=20+19) QuoteMetaNone-4 25.3MB/s ± 3% 131.5MB/s ± 0% +419.28% (p=0.000 n=17+19) name old alloc/op new alloc/op delta QuoteMetaAll-4 64.0B ± 0% 64.0B ± 0% ~ (all samples are equal) QuoteMetaNone-4 96.0B ± 0% 0.0B ±NaN% -100.00% (p=0.000 n=20+20) name old allocs/op new allocs/op delta QuoteMetaAll-4 2.00 ± 0% 2.00 ± 0% ~ (all samples are equal) QuoteMetaNone-4 2.00 ± 0% 0.00 ±NaN% -100.00% (p=0.000 n=20+20) Change-Id: I38d50f463cde463115d22534f8eb849e54d899af Reviewed-on: https://go-review.googlesource.com/31395 Reviewed-by: Russ Cox <rsc@golang.org> Reviewed-by: Austin Clements <austin@google.com> Run-TryBot: Brad Fitzpatrick <bradfitz@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org>		2016-10-19 07:09:08 +00:00
