Revision history for Perl extension Class-MOP. 0.55 ~ added MRO::Compat as a dependency ~ ~ all classes now have proper c3 support ~ * Class::MOP::Class - rebless_instance now returns the instance it has just blessed, this is mostly to facilitate chaining - set the attr correctly in rebless_instance when it has no init_arg - tweaked &linear_isa and &class_precedence_list to support c3 classes. 0.54 Fri. March, 14, 2008 * Class::MOP metaclass.pm - making sure that load_class never gets passed a value from @_ or $_ to squash Ovid's bug (http://use.perl.org/~Ovid/journal/35763) * Class::MOP::Class - make_{immutable,mutable} now return 1 (cause Sartak asked) - improved error handling in ->create method - rebless_instance now takes extra params which will be used to populate values - added tests for this * Class::MOP::Object - localizing the Data::Dumper configurations so that it does not pollute others (RT #33509) * Class::MOP::Class Class::MOP::Package Class::MOP::Module Class::MOP::Method Class::MOP::Attribute - these classes no longer define their own ->meta, but instead just inherit from Class::MOP::Object * Class::MOP::Instance Class::MOP::Immutable - these classes now inherit from Class::MOP::Object * t/ - fixed the filename length on several test files so we install on VMS better (RT #32295) - fixed incorrect use of catdir when it should be catfile (RT #32385) 0.53 Thurs. Feb. 14, 1008 ~~ several doc. fixes and updates ~~ * Class::MOP::Class Class::MOP::Method::Constructor Class::MOP::Attribute - making init_arg accept an undefined value to indicate that no constructor args can be passed (thanks to nothingmuch) - added tests for this - added attribute initializer attribute (rjbs) * Class::MOP. - making this use the new init_arg => undef feature instead of the silly hack from before (thanks to nothingmuch) 0.52 Tues. Jan. 22, 2008 * Class::MOP::Class - fixed bug in rebless_instance (discovered by ash) * Class::MOP::Method::Constructor - removed assumptions about the existence of a &meta method 0.51 Mon. Jan. 14, 2008 ~~~ some misc. doc. fixes ~~~ ~~ updated copyright dates ~~ * Class::MOP - now sets the IS_RUNNING_ON_5_10 constant so that we can take advantage of some of the nice bits of 5.10 * Class::MOP::Class - uses the IS_RUNNING_ON_5_10 flag to optimize the &linearized_isa method and avoid the hack/check for circular inheritence in &class_precedence_list - added rebless_instance method (Sartak) - added tests for this * Class::MOP::Immutable - the immutable class now keeps track of the transformer which immutablized it * Class::MOP::Instance - added rebless_instance_structure method (Sartak) - added tests for this 0.50 Fri. Dec. 21, 2007 * Class::MOP::Class - fixed bug in immutable to make sure that transformation arguments are saved correctly (mst) - added tests for this * Class::MOP::Immutable - fixed a bug (see above) * Class::MOP::Attribute - some doc updates 0.49 Fri. Dec. 14, 2007 !! Class::MOP now loads 2 x faster !! !! with XS speedups (thanks konobi) !! * Class::MOP - removed the dependency on B - added two XS functions (thanks konobi) - get_code_info($code) which replaces all the B fiddling we were doing with faster/leaner XS level fiddling - check_package_cache_flag($pkg_name) which returns the PL_sub_generation variable to be used to help manage method caching. NOTE: In 5.10 or greater this will actually use the mro::get_pkg_gen instead to give even more accurate caching information. blblack++ for that stuff :) * Class::MOP::Class - added the &subclasses method (thanks rlb) - added the update_package_cache_flag and reset_package_cache_flag which help keep track of when we need to re-fetch the method map. - Several small improvements to take advantage of the new method map caching features 0.48 Mon. Nov. 26, 2007 * Class::MOP::Attribute - fixed get_read/write_method to handle the HASH ref case, which makes the get_read/write_method_ref handle it too. - added more tests for this 0.47 Sat. Nov. 24, 2007 * Class::MOP::Attribute - fixed misspelling in get_write_method_ref - added more tests for this 0.46 Fri. Nov. 23, 2007 * Class::MOP::Class - added the linearized_isa method instead of constantly pruning duplicate classes (this will be even more useful in the 5.10-compat version coming soon) * Class::MOP::Attribute - added the get_read_method_ref and get_write_method_ref methods which allow you to retrieve a CODE ref which can always be used to read or write an attribute. 0.45 Thurs. Nov. 13, 2007 * Class::MOP::Attribute - Fix error message on confess (groditi) 0.44 Thurs. Nov. 13, 2007 - Apparently I didn't make dist correctly (groditi) 0.43 Thurs. Nov. 13, 2007 * Class::MOP - Add support for the 'builder' attribute (groditi) * Class::MOP::Class - optimise metaclass-already-exists check in construct_class_instance (groditi) - duplicate check into initialize to save a call through (groditi) * Class::MOP::Attribute - Add support for the 'builder' attribute (groditi) - Make predicates check for the existence of a value, not whether it is defined (groditi) * Class::MOP::Instance - Make predicates check for the existence of a value, not whether it is defined (groditi) * Class::MOP::Method::Accessor - made this a subclass of Class::MOP::Method::Generated - removed the relevant attributes * Class::MOP::Method::Constructor - fixed the cached values we had to be more sane - made this a subclass of Class::MOP::Method::Generated - fixed generated constructor so it properly handles subclasses now. - added tests for this - added the option to allow for both inlined and non-inlined constructors. - Update inlined methods for builder and predicate changes (groditi) * Class::MOP::Method::Generated - added this class as an abstract base for the Class::MOP::Method::{Constructor,Accessor} classes - added tests for this *t/ - Alter tests (005, 014 020, 021) for new builder addition (groditi) - Tests for new predicate behavior (and corrections to old tests) (groditi) *examples/ - Update ArrayRef based class example to work with predicate changes 0.42 Mon. July 16, 2007 !!! Horray for mst, he fixed it !!! * Class::MOP::Package - alter symbol table handling to deal with 5.8.x and 5.9.x * t/ - Get rid of the crappy workaround from 0.40/41 0.41 Sun. July 15, 2007 * t/ Arghh!!! My TODO test didn't work, so I handle it manually now so that people can use this with 5.9.5/bleadperl without issue. 0.40 Tues, July 3, 2007 * t/ ~ marked a test in 003_methods.t as TODO for perl 5.9.5 (this test is irrelvant to the module functioning on 5.9.5 for the most part anyway) 0.39 Mon. June 18, 2007 * Class::MOP::Immutable - added make_metaclass_mutable + docs (groditi) - removed unused variable - added create_immutable_transformer necessary for sane overloading of immutable behavior - tests for this (groditi) * Class::MOP::Class - Immutability can now be undone, added make_mutable + tests + docs (groditi) - Massive changes to the way Immutable is done for details see comments next to make_immutable This fixes a bug where custom metaclasses broke when made immutable. We are now keeping one immutable metaclass instance per metaclass instead of just one to prevent isa hierarchy corruption. Memory use will go up, but I suspect it will be neglible. - New tests added for this behavior. (groditi) 0.38 Thurs. May 31, 2007 ~~ More documentation updates ~~ * Class::MOP::Package - we now deal with stub methods properly - added tests for this - fixed some tests failing on 5.9.5 (thanks blblack) * Class::MOP::Attribute - added get_read_method and get_write_method thanks to groditi for this code, tests and docs. - added tests and POD for this * Class::MOP::Class - fixed RT issue #27329, clone object now handles undef values correctly. - added tests for this - Corrected anon-class handling so that they will not get reaped when instances still exist which need to reference them. This is the correct behavior, hopefully this is an obscure enough feature that there are not too many work arounds out in the wild. - added tests for this by groditi - updated docs to explain this * metaclass - load custom metaclasses automatically (thanks groditi) - added tests for this behavior 0.37 Sat. March 10, 2007 ~~ Many, many documentation updates ~~ * Class::MOP - added &load_class and &is_class_loaded - added tests and docs for these * Class::MOP::Attribute - default now checks the instance with defined to avoid setting off bool-overloads (found by Carl Franks) 0.37_002 * /t - bad name in a test, causing meaningless failuress. No other changes. 0.37_001 ~~ GLOBAL CHANGES ~~ - All attribute names are now consistent and follow Perl 6 style (prefixed with the sigil, and ! as the twigil for private attrs). This should not affect any code, unless you broke encapsulation, in which case, it is your problem anyway. !! Class::MOP::Class::Immutable has been removed * Class::MOP::Method::Constructor - this has been moved out of Class::MOP::Class::Immutable and is a proper subclass of Class::MOP::Method now. * Class::MOP::Class - this module now uses Class::MOP::Immutable for the immutable transformation instead of Class::MOP::Class::Immutable. + Class::MOP::Immutable - this module now controls the transformation from a mutable to an immutable version of the class. Docs for this will be coming eventually. 0.36 Sun. Nov. 5, 2006 * Class::MOP::Class - added a few 'no warnings' lines to keep annoying (and meaningless) warnings from chirping during global destruction. * Class::MOP - some more bootstrapping is now done on the new classes * Class::MOP::Class::Immutable *** API CHANGE *** - constructor generation is now handled by the Class::MOP::Method::Constructor class * Class::MOP::Method::Constructor - created this to handle constructor generation in Class::MOP::Class::Immutable * Class::MOP::Attribute *** API CHANGE *** - attributes now delegate to the Class::MOP::Method::Accessor to generate accessors * Class::MOP::Method::Accessor - all accessor generation functions from Class::MOP::Attribute have been moved here 0.35 Sat. Sept. 30, 2006 * scripts/class_browser.pl - initial prototype of a class browser, more on this to come. Comments and patches are very much welcome. * Class::MOP - All Class::MOP::* accessors are no longer re-generated in the bootstrap, instead they are aliased from the originals - fixed tests to reflect - added Class::MOP::Method (and its subclasses) to the bootstrap - adjusted tests for this - added the Class::MOP::Instance attributes to the bootstrap * Class::MOP::Method *** API CHANGE *** - methods are no longer blessed CODE refs but are actual objects which can be CODE-ified - adjusted tests to compensate - adjusted docs for this * Class::MOP::Class - changed how methods are dealt with to encapsulate most of the work into the &get_method_map method - made several adjustments for the change in Class::MOP::Method - &add_attribute now checks if you are adding a duplicate name, and properly removes the old one before installing the new one - added tests for this - adjusted docs for this * Class::MOP::Class::Immutable - added caching of &get_method_map - fixed issue with &get_package_symbol - cleaned up the methods that die (patch by David Wheeler) * Class::MOP::Package - added filtering capabilities to &list_all_package_symbols 0.34 Sat. Aug. 26, 2006 * Class::MOP::Class - added the %:methods attribute, which like the $:version and such just actually goes to the symbol table to get it's stuff. However, it makes the MOP more complete. ** API CHANGE ** - The &create method now requires that all but the package name now is passed in as named parameters. See docs for more info. - updated docs and tests for this * Class::MOP::Object - added &dump method to easily Data::Dumper an object * Class::MOP - cleaned up the initialization of attributes which do not store things in the instance - added the %:methods attribute definition to the bootstrap ~ lots of misc. test cleanup 0.33 Sat. Aug. 19, 2006 * Class::MOP::Class - moved the metaclass cache out of here and it is now in Class::MOP itself. * Class::MOP - moved all the metaclass cache stuff here - fixed all tests for this * Class::MOP::Attribute - reference values (other than CODE refs) are no longer allowed for defaults - added tests for this * Class::MOP::Package - fixed an issue with perl 5.8.1 and how it deals with symbol tables. The namespace hash is now always reloaded from the symbol table. ~ lots of misc. documentation cleanup 0.32 Sat. Aug. 12, 2006 + added Class::MOP::Object so that the metamodel is more complete (and closer to what Perl 6 will probably be). * Class::MOP::Package - refactored entire class, this is now the primary gateway between the metaclass and the Perl 5 symbol table - added many tests for this - this class is now a subclass of Class::MOP::Object - added some tests to reflect this * Class::MOP::Class - refactored all symbol table access to use Class::MOP::Package methods instead * Class::MOP::Module - adding the $:version attribute in the bootstrap so that Module has a version as an attribute - see comment in Class::MOP for details - added the $:authority attribute to this module as well as an &identifier method, to bring us ever closer to Perl 6 goodness - I have added $AUTHORITY to all the modules - added tests for this * Class::MOP::Instance - added &deinitialize_slot for removing slots from an instance - added tests for this * Class::MOP::Attribute - added support for &deinitialize_slot for removing slots from an instance - added tests for this 0.31 Sat. July 15, 2006 * Class::MOP::Class - added &find_method_by_name to locate a method anywhere within the class hierarchy * Class::MOP::Attribute - added &set_value and &get_value for getting the value of the attribute for a particular instance. 0.30 Wed. July 5, 2006 --------------------------------------- This is the first version of Class::MOP to introduce the immutable features which will be used for optimizating the MOP. This support should still be considered experimental, but moving towards stability. --------------------------------------- * Created Class::MOP::Class::Immutable * Created the Class::MOP::Package and Class::MOP::Module classes to more closely conform to Perl 6's meta-model * Class::MOP::Class - now inherits from Class::MOP::Module - several methods moved to ::Module and ::Package and now inherited - added tests for this * Class::MOP::Instance - added an is_inlinable method to allow other classes to check before they attempt to optimize. - added an inline_create_instance to inline instance creation (of course) ** API CHANGE ** - the Class::MOP::Class::*_package_variable methods are all now methods of Class::MOP::Package and called *_package_symbol instead. This is because they are now more general purpose symbol table manipulation methods. 0.29_02 Thurs. June 22, 2006 ++ DEVELOPER RELEASE ++ * Class::MOP::Class - small change in &create so that it behaves properly when inherited - small fix to &clone_instance 0.29_01 Fri. May 12, 2006 ++ DEVELOPER RELEASE ++ - This release works in combination with Moose 0.09_01, it is a developer release because it introduces a new instance sub-protocol and has not yet been optimized. * Class::MOP::Class - anon-classes are now properly garbage collected - added tests for this - improved method modifier wrapping * Class::MOP::Instance - added new instance protocol - added tests for this - changed all relevant modules and examples - Class::MOP::Class - Class::MOP::Attribute - examples/* * metaclass - you no longer need to specify the metaclass itself, if it is not there, Class::MOP::Class is just assumed - updated tests for this * examples/ - added ArrayBasedStorage example to show instance storage using ARRAY refs instead of HASH refs. - added tests for this - InsideOutClass is totally revised using the new instance protocol - added more tests for this 0.26 Mon.
