6.0.8

New features:

• Support PHPStan/Psalm-style conditional return types such as @return ($x is null ? A : B) in @return, @psalm-return and @phan-return; add PhanCommentReturnConditionalWithoutRealParam (#5574, #5576)
• Add --dump-phase-timings and --phase-timings-json <path> to report the time and memory of each phase of a run (#5583)
• Add the process_file_assignment config setting to balance files across --processes N analysis processes (#5589)
• Infer positive-int, negative-int and non-zero-int for arithmetic results when the sign is known (#5577, #5580)

Performance improvements:

• Reduce FQSEN, Type and UnionType overhead and skip redundant realpath()/stat calls and the clone normalization pass for files without clone (#5564, #5586)
• Reduce the per-inherited-method cost of the class and method analysis phases (#5587)
• Speed up the parse phase by about 12 % on large projects (#5591)
• Skip emit-only declaration checks of functions and methods declared in excluded files (#5588)
• Skip the @phan-mandatory-param and @throws ancestor walks of inherited methods when they cannot find anything (#5590)
• Replay the declaration analysis of inherited methods instead of repeating it (#5592)
• Exit --processes N analysis workers without PHP's shutdown sequence to avoid copying shared pages (PHAN_DISABLE_FAST_EXIT=1 restores the old behavior) (#5585)

Bug fixes:

• Make the output of --processes N deterministic by combining worker results in worker order (#5584)
• Narrow the receiver of a nullsafe access ($x?->method(), $x?->prop) to non-null in conditions that imply the access succeeded (#5569, #5571)
• Keep the real type of constants declared with define() and infer constant('NAME') for them (#5542, #5570)
• Fix false positives when a branch calls a never-returning method on a variable assigned with new ClassName() (#5553, #5554)
• Fix crash in is_callable() narrowing on intersection types (#5555, #5557)
• Fix @var Foo<T> losing its template parameter on properties with a native type declaration (#5556, #5560)
• Fix static calls on class-string<Foo> variables not resolving (#5558, #5561)
• Fix false positive PhanTypeMismatchPropertyDefault for promoted property defaults using a class declared later (#5578, #5581)
• Fix false positive PhanImpossibleConditionInGlobalScope when a loop in the global scope precedes a function that modifies a global (#5575, #5579)
• Fix false positive PhanParamTooFewInternal for array_diff(), array_intersect() and related functions called with one array (#5566, #5568)
• Fix array_is_list() being false narrowing arrays to non-empty-associative-array<array> (#5565, #5567)
• Infer the return type of hrtime() from its $as_number argument (#5550)
• Infer the return type of substr_replace() from its $string argument (#5551, #5552)
• Fix parameter signatures of imagecreatefromavif() and imageavif() (#5562, #5563)

Miscellaneous:

• Add tool/perf/ scripts for benchmarking and profiling Phan (#5582)
• Update squizlabs/php_codesniffer to 3.13.6 in internal/PHP_CodeSniffer (#5559)
