Implemented concept of "delayed early binding" that allows opcode caches to perform class declaration (early and/or run-time binding) in exactly the same order as vanila php. The following pseudo-code explains how it should be used in opcode cache. function cache_compile_file($filename) { if (!is_cached($filename)) { ... orig_compiler_options = CG(compiler_optins); CG(compiler_options) |= ZEND_COMPILE_IGNORE_INTERNAL_CLASSES | ZEND_COMPILE_DELAYED_BINDING; $op_array = orig_compile_file($filename); CG(compiler_options) = orig_copiler_options; ... } else { $op_array = restore_from_cache($filename); } zend_do_delayed_early_binding($op_array); }

Implemented Traits for PHP as proposed in the RFC [TRAITS] # RFC http://wiki.php.net/rfc/horizontalreuse#traits_-_reuse_of_behavior # Ok, here we go, I guess that will result in more discussion, which is fine # by me. But now, the patch is here, and properly archived. # # See below a list of notes to the patch, it also includes a list of # points which should be fixed # # Internals of the Traits Patch # ----------------------------- # # Open TODOs # """""""""" # # - Reflection API # - support for traits for internal classes # - currently destroy_zend_class does not handle that case # # Introduced Structures # """"""""""""""""""""" # # Data structures to encode the composition information specified in the # source: # - zend_trait_method_reference # - zend_trait_precedence # - zend_trait_alias # # Changes # """"""" # # zend_class_entry # - uses NULL terminated lists of pointers for # - trait_aliases # - trait_precedences # - do you prefer an explicit counter? # - the information is only necessary during class composition # but might be interesting for reflection # - did not want to blow up class further with not really necessary length counters # # added keywords # - trait # - insteadof # # Added opcodes # ZEND_ADD_TRAIT # - similar to ZEND_ADD_INTERFACE # - adds the trait to the list of traits of a class, no actual composition done # ZEND_BIND_TRAITS # - emitted in zend_do_end_class_declaration # - concludes the class definition and will initiate the trait composition # when the class definition is encountered during runtime # # Added Flags # ZEND_ACC_TRAIT = 0x120 # ZEND_ACC_IMPLEMENT_TRAITS = 0x400000 # ZEND_FETCH_CLASS_TRAIT = 14 # # zend_vm_execute.h # - not sure whether the handler initialization (ZEND_ADD_TRAIT_SPEC_HANDLER, # ZEND_BIND_TRAITS_SPEC_HANDLER) is correct, maybe it should be more selective # # zend_compile.c # - refactored do_inherit_method_check # split into do_inherit_method_check and do_inheritance_check_on_method # - added helper functions use a '_' as prefix and are not mentioned in the # headers # - _copy_functions # prepare hash-maps of functions which should be merged into a class # here the aliases are handled # - _merge_functions # builds a hash-table of the methods which need to be added to a class # does the conflict detection # - reused php_runkit_function_copy_ctor # - it is not identical with the original code anymore, needed to update it # think I fixed some bugs, not sure whether all have been reported back to runkit # - has to be renamed, left the name for the moment, to make its origin obvious # - here might be optimization potential # - not sure whether everything needs to be copied # - copying the literals might be broken # - added it since the literals array is freed by efree and gave problems # with doubled frees # - all immutable parts of the zend_op array should not be copied # - am not sure which parts are immutable # - and not sure how to avoid doubled frees on the same arrays on shutdown # - _merge_functions_to_class # does the final merging with the target class to handle inherited # and overridden methods # - small helper for NULL terminated lists # zend_init_list, zend_add_to_list # # zend_language_parser.y # - reused class definition for traits # - there should be something with regard to properties # - if they get explicitly defined, it might be worthwhile to # check that there are no collisions with other traits in a composition # (however, I would not introduce elaborate language features to control that # but a notice for such conflicts might be nice to the developers)
