From 91692846909ed191addb7ec1c34aad11392ab88b Mon Sep 17 00:00:00 2001 From: nsfisis Date: Sat, 18 Jul 2026 15:03:55 +0900 Subject: perf(regex): eliminate per-call clone overhead in preg_* dispatch regex::Regex::clone() does not share the underlying meta engine's search-cache pool, so every fresh clone pays a ~10us warmup cost on its first use. Two changes together eliminate this across nearly all preg_* call sites: - A php_regex! macro resolves PHP-style patterns to a per-call-site &'static regex::Regex (via regex-macro's LazyLock), applied at the majority of call sites throughout the codebase. - Call sites still passing dynamic pattern strings go through PATTERN_CACHE, which now stores Arc<(Regex, bool)> and hands out Arc::clone()s instead of cloning the Regex itself. PregPattern::resolve() returns a ResolvedPattern enum (Arc or 'static reference) rather than an owned Regex, so neither path ever clones the Regex proper.
