0.20.0

[Jeckerson]

Added

• Added support of PHP 8.5 #2459, #2461
• Added closure this and use support: closures can now reference this to call methods and access properties of the enclosing class #2497, #2503
• Added support for char and uchar literal/variable values as method arguments to parameters typed char/uchar #2469, #2507
• Added support for typed constants (PHP 8.3+) in generated stubs #2498
• Added PhpStan/Psalm tag pass-through whitelist for class-level docblocks in generated stubs #2501
• Added validation of @phpstan-return, @phpstan-var, @phpstan-type, @phpstan-param, @phpstan-import-type and Psalm equivalents (delegates parsing to phpstan/phpdoc-parser) #2502
• Added ConstructorsCodeGenTest to verify generated C/H files against reference fixtures #2482

Changed

• Refactored string parameter handling to use native zend_string * (with companion zval) where the parameter isn't mutated, reducing engine round-trips for string params #2462, #2484
• Refactored type optimizers and added more tests #2470
• Refactored header compilation logic and updated compatibility checks for PHP 8.5 #2489
• Bumped phpstan/phpdoc-parser from 1.33.0 to 2.3.2 #2504
• Bumped squizlabs/php_codesniffer from 3.13.5 to 4.0.1 #2473
• Bumped phpunit/phpunit from 9.6.32 to 9.6.33 #2471
• Bumped codecov/codecov-action from 3 to 6 #2472, #2488
• Bumped actions/checkout to 6, actions/cache to 5, actions/upload-artifact to 7, actions/download-artifact to 8 #2474, #2475, #2476, #2477, #2480, #2481, #2464

Fixed

• Fixed -Wincompatible-pointer-types warnings on PHP 8.5+ for zend_parse_arg_array (Z_PARAM_ARRAY/Z_PARAM_ARRAY_OR_NULL) — promoted to error by GCC 14+ #2462, #2463, #2483, #2508
• Fixed -Wdiscarded-qualifiers warnings introduced on PHP 8.5 where EG(fake_scope) became const zend_class_entry * (kernel/object.c, kernel/require.c, ZEPHIR_BACKUP_SCOPE/ZEPHIR_RESTORE_SCOPE macros) #2462
• Fixed memory leak in generated code where native zend_string * parameters incremented refcount via ZVAL_STR_COPY without a matching decrement on the return path (~3.4 KB per call) #2500, #2506
• Fixed crash when passing a char/uchar literal or variable to a method parameter declared as char/uchar (TypeError in getResolvedParams) #2469, #2507
• Fixed stale .dep dependency files causing compilation failures when switching between PHP 8.x versions (now removed during fullclean; build order corrected so make clean runs before phpize --clean) #2490, #2491
• Fixed missing default values in reflection metadata for method parameters with scalar types #2457
• Fixed various compiler warnings surfaced by recent GCC/Clang #2445
• Fixed backtrace.c so PHP_VERSION_ID is visible (added missing PHP header include)
