…first - Reorder checks to prioritize definition lookup which is the most common case - Return true immediately if definition exists - Only check tag aliases if definition doesn't exist - Return false if neither exists Performance improvements: - benchPredefinedExisting: ~29% faster (130μs → 92μs) - benchUndefinedExisting: ~29% faster (123μs → 87μs) - benchUndefinedNonexistent: ~1% faster (446μs → 441μs) - Small improvements in other benchmarks
- Add fast path for existing instances - Extract StateResetter logic into separate method - Move StateResetter check to the end to avoid duplicate instance access - Improve code readability and maintainability Performance improvements: - benchSequentialLookups: ~3% faster (620μs → 599μs) - benchUndefinedExisting: ~5% faster (87μs → 83μs) - Other benchmarks show similar or slightly improved performance
- Add early returns for common simple cases (strings, ContainerInterface, Closure) - Simplify array definition handling - Improve code readability and reduce nesting Performance improvements: - benchConstruct: ~29% faster (336μs → 238μs) - benchSequentialLookups: ~13% faster (599μs → 523μs) - benchRandomLookups: ~16% faster (621μs → 524μs) - benchRandomLookupsComposite: ~9% faster (2.3ms → 2.1ms) - benchUndefinedNonexistent: ~5% faster (464μs → 440μs)
- Add normalized definitions cache with memory management - Reorder checks to prioritize most common cases - Add fast path for circular reference check - Improve code readability with better comments Performance improvements: - benchRandomLookupsComposite: ~4% faster (2.3ms → 2.2ms) - benchSequentialLookups: ~2% faster (544μs → 539μs) - benchRandomLookups: ~1.5% faster (546μs → 525μs) Memory usage is kept in check by clearing the cache when it reaches 100 entries.
- Simplify exception handling paths - Add fast path for NotFoundException with matching ID - Use ternary operators for cleaner code - Improve code readability with better comments Performance improvements: - benchRandomLookupsComposite: ~1% faster (2.2ms → 2.18ms) - benchSequentialLookups: ~0.5% faster (539μs → 536μs) - benchRandomLookups: ~0.5% faster (541μs → 538μs)
- Skip parsing if already a valid definition - Only validate meta if it's not empty - Only unset instance if it exists - Improve code readability with better comments Performance improvements: - benchConstruct: ~10% faster (238μs → 213μs) - benchSequentialLookups: ~3.5% faster (536μs → 517μs) - benchRandomLookups: ~3.7% faster (538μs → 518μs) - benchRandomLookupsComposite: ~0.5% faster (2.18ms → 2.17ms)

Use array_key_exists instead of isset. Theoretically, result may be null.

There was a problem hiding this comment.
Seems we should catch any exceptions from previous "catch" blocks also (for example, exceptions from delegates).

Did some fixes. @vjik can you help with Psalm? I can ignore mixed returns but, I guess, it could be solved in a better way. |
