From 69aca4fe1260066eee23e54c5a53cd0f26ac661b Mon Sep 17 00:00:00 2001 From: Nejc Date: Thu, 28 May 2026 13:25:32 +0200 Subject: [PATCH 1/6] perf(vector): replace array_map closures with foreach + trusted ctor MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit AbstractVector hot paths (add, subtract, scale, dot, distance, magnitude, normalize) all used array_map(fn) with a closure invoked per component. The closure allocation + variadic call dominated the runtime — magnitude on a Vec2 was spending 3.7us doing 2 multiplies. Two changes: 1. Rewrite all hot methods to use foreach with direct index access. Same algorithm, no closures. 2. Add bool \$trusted = false constructor flag on AbstractVector.

Five small fixes, each individually small, compound on hot paths (Laravel form requests, batch deserialization, etc.): 1. Inline validateField() into the constructor loop. The method call cost wasn't huge but it's per-field. 2. Skip the rules loop entirely when rules === []. The previous code invoked array_all with a closure even on fields with no rules, which is the common case. 3. Replace array_all(closure) with foreach. Closure allocation per field x per validation = wasted frames. 4. Type-dispatch via match() instead of an if-cascade with seven string comparisons. PHP's match generates a jump table. 5. Resolve values with isset() first, falling through to array_key_exists() only when the key is missing-or-null. Most values aren't null, so the common path is now a single isset. Also replaced reset() (which mutates the array pointer) with array_key_first() in the BC-format detection at the top of the constructor.

For a typical form-request flow that validates the same property across many items in a payload (or many requests in a worker process), the reflection work dominates: ~1.5us per attribute, repeated forever. Cache the parsed attribute instances keyed by 'Class::property'. Property structure doesn't change at runtime, so we instantiate once and reuse. Also added a public static clearCache() for long-running processes that reload classes (rare) and for tests that need a clean slate.

AdvancedStruct (nearly identical to pre-opt Struct): - isset() fast-path for value resolution - skip the rules foreach when rules === [] - match() type dispatch instead of if-cascade - isValidType() made static ImmutableStruct (different shape, narrower wins): - inline nullable detection (\$type[0] === '?') instead of method calls to isNullable() + stripNullable() - only call get_debug_type() when an error is about to be thrown, not eagerly - skip the rules foreach when no rules are declared Numbers (avg of 3x 20k iter runs): AdvancedStruct (8 fields): ~14.5us -> ~8.6us (1.69x) ImmutableStruct (8 fields): ~48.8us -> ~39.0us (1.25x) ImmutableStruct's smaller win reflects irreducible overhead from parent inheritance, separate initialize/setInitial phases, and frozen-state tracking.
