Released Rector 2.8.1

Fixes

• Fix crash cache due to PHPStan Turbo (#8850)

Released Rector 2.8

Faster runs, single-pass rules, and a leaner rule set 🚀

The Rector core engine is ~26 % faster (1.36x) with ~8 % less memory than 2.7.0.

If you run PHP 8.3+, it's 3x faster using PHPStan Turbo, the native parsing extension shipped with phpstan/phpstan:

Rev	Core engine (time / peak RSS)
2.7.0	32.0s / 351 MB
2.8.0	23.6s / 324 MB
2.8.0 + PHPStan Turbo (PHP 8.3+)	~10.0s / ~317 MB

Turbo factor measured on this release via an A/B run on Rector's own rules/ (24-core host, PHP 8.4, cold, identical changed-file fingerprint): ~2.4x wall and ~2.6x worker CPU. Turbo speeds up PHPStan parsing in the workers, so the wall-time gain scales with the available core count.

This release is mostly about speed and reliability. A large performance campaign hoists cheap node guards in front of expensive reflection, scope and type lookups across hundreds of rules, replaces per-node config scans in configurable rules with keyed lookups, and resolves short names and unused imports in a single AST walk.

Rules now converge in a single pass: instead of a re-processing guard, the engine iterates rules to a fixed point and tests enforce idempotency, so a rule that changes a file produces the same result whether it runs once or many times.

We also trimmed the rule set: many niche, context-dependent rules that are not part of any set and rarely used are now deprecated. Deprecated rules still run and print a warning; they will be removed in a future major release. The goal is a smaller set of valuable, reliable rules for everyday upgrades.

New features 🥳

• [CodeQuality] Add ExplicitNullableObjectInstanceRector, replacing 4 nullable-object instanceof rules (#8636)
• [Console] Add --all option to list-rules to list every rule in core and rector-* packages (#8637)
• [Console] Undeprecate the list-rules command (#8533)
• Respect cgroup/CFS CPU quota when picking the parallel worker count (#8559)
• Bump to PHPStan 2.3

Performance Improvements 🚀

• Run the parallel workers with PHPStan Turbo, the native parsing extension shipped with phpstan/phpstan, on PHP 8.3+ - no main-process restart, the workers do the analysis (#8812) Thanks @​SanderMuller
• Retarget class-level rules to a single Class_/ClassLike node and add getClassReflection() to AbstractRector: RemoveParentDelegatingClassMethodRector, ReturnTypeFromMockObjectRector, AddVoidReturnTypeWhereNoReturnRector and ChangeMethodVisibilityRector (#8824, #8827, #8828, #8830, #8831)
• Hoist the repeated fully qualified name build in UseImportNameMatcher::resolveName() and resolve the parent class reflection by name in Php4ConstructorRector (#8841, #8838)
• Drop scope attachment on pre/post increment expressions and remove an unneeded array_values() in BetterStandardPrinter::pArray() (#8814, #8821)
• Hoist cheap name and structural guards before reflection, scope and type lookups across CodeQuality, DeadCode, CodingStyle, TypeDeclaration, Transform, EarlyReturn and legacy Php rules (#8664, #8666, #8667, #8668, #8669, #8670, #8671, #8672, #8661, #8663)
• Replace per-node config scans with keyed lookups in configurable rules - method, property, rename, transform, arguments and removing rules (#8734, #8735, #8736, #8739, #8742, #8743, #8744, #8745)
• Iterate rules to a fixed point with a content-cycle guard instead of a per-node re-processing guard, and enforce single-pass idempotency in tests (#8679, #8719, #8715, #8722)
• Skip rules whose work depends on a docblock when the node has none (#8624, #8625, #8626, #8627, #8628, #8629, #8630, #8631, #8632)
