1 Revision history for Perl extension Class-MOP.
6 - Move get_method_map and its various scaffolding into
10 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method
11 object as the first argument, rather than just a
14 * Class::MOP::Attribute
16 - Allow attribute names to be false (while still requiring them to be
20 * Class::MOP::Method::Wrapped
21 - Fixing variable usage issues with the patch from previous
22 version, not properly using lexicals in the for
26 Japan Perl Association has sponsored Goro Fuji to improve startup
27 performance of Class::MOP and Moose. These enhancements may break
28 backwards compatibility if you're doing (or using) complex
29 metaprogramming, so, as always, test your code!

34 - Anonymous classes were not completely destroyed when they went
35 out of scope, leading to a memory leak. RT #47480. (Goro
39 - The get_method, has_method, and add_method methods no longer
40 use get_method_map. Method objects are instantiated
41 lazily. This significantly improves Class::MOP's load
45 - Inline fewer metaclass-level constructors since the ones we
46 have are perfectly fine. This reduces the number of string
49 * Class::MOP::Method::Wrapped
50 - If a method modifier set $_, this caused the modifier to blow
51 up, because of some weird internals. (Jeremy Stashewsky)
55 * Class::MOP::Class::Immutable::Trait
56 - Made the Trait act like a role with a bunch of "around"
57 modifiers, rather than sticking it in the inheritance
58 hierarchy. This fixes various problems that caused with
59 metaclass compatibility, which broke Fey::ORM.
62 - Allow a blessed code reference as the method body. Fixes a
63 problem interaction with MooseX::Types. (ash)
65 * Class::MOP::Instance
66 - add inline version of rebless_instance_structure. (doy)
67 - change inline_slot_access to use single quotes (gphat)
69 0.88 Tue, Jun 23, 2009
71 - Moved the __INSTANCE__ parameter to _construct_instance from
73 - Fixed some issues involving metaclasses of metaclasses and
76 0.87 Sun, Jun 21, 2009
78 - Made sure to always local-ize $@ and $SIG{__DIE__} before
79 calling an eval. Fixes RT #45973.
82 - Synced docs about immutability with the current reality (which
83 changed back in 0.82_01)
84 - Removed the immutable_transformer method, which had been
85 returning undef since 0.82_01 anyway.
88 - Got rid of tests which needed Moose and improved testing of
89 constructor/destructor inlining warnings. Fixes RT #47119.
91 0.86 Tue, Jun 16, 2009
93 - If you redefined a subroutine at runtime and then wrapped it
94 with a method modifier, the modifier could in some cases wrap
95 the original version of the subroutine. Fixes RT #46957.
98 - make_immutable issues a warning instead of overriding an
99 existing DESTROY method (Dylan William Hardison). Fixes RT
102 0.85 Sat, Jun 6, 2009
103 * Class::MOP::Attribute
104 - Allow default values to be Class::MOP::Methods. (Florian
106 - Test the above. (Rhesa Rozendaal)
107 - Tweak original commit so the intent matches the accepted
108 behavior (Nicholas Perez)
111 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
114 - Add direct_subclasses method (Sartak)
115 - Tests for subclasses and direct_subclasses (Sartak)
116 - subname is no longer used unconditionally in add_method, but
117 only if the code reference's name is '__ANON__' (nothingmuch)
118 - Add a hook for _superclasses_updated (Sartak)
121 - Remove long, old warning about possibly outdated modules
124 0.84 Tue, May 12, 2009
126 - Depend on Text::Exception 0.27 to avoid failing tests ond old
130 - Made is_class_loaded a little stricter. It was reporting that
131 a class was loaded if it merely had an @ISA variable in its
132 stash. Now it checks that the @ISA var has elements in it.
133 - Deprecate in_global_destruction and subname re-exporting
137 - Explicitly use Devel::GlobalDestruction and Sub::Name
140 * Class::MOP::Package
141 - Disable prototype mismatch warnings for add_package_symbol.
144 - Add test for finding methods from $meta->name->meta before immutable,
147 0.83 Mon, April 27, 2009
149 - Fix segfault when calling get_method_map on a metaclass for an empty
152 0.82_02 Fri, April 24, 2009
153 * Class::MOP::Method::Inlined
154 - Don't inline if the expected method is not defined at all (happens with
155 e.g. Moose::Object::_new is the expected method due to an overridden
158 - Some tests were trying to load Class::MOP::Immutable, which
159 was removed in 0.82_01.
161 0.82_01 Thu, April 23, 2009
162 * Class::MOP::Immutable (and others)
163 - Refactor the immutability system to use a pre-defined class
164 for the immutable metaclass of Class::MOP::Class::Immutable::$class
165 - Rather than generating methods into this class every time, use
166 a Trait (basic mixin) to supply the cached methods
167 - Remove the hack that returns the mutable metaclass for
168 metacircularity in order to provide consistent meta-metaclasses
169 for the Moose compatibility handling code
170 (mst broke it, nothingmuch fixed it)
172 0.82 Mon, April 20, 2009
174 - The deprecation wrappers for some renamed methods were not
175 passing arguments to the new method. (nothingmuch)
177 * Class::MOP::Immutable
178 - Warn during immutablization if the local class provides its own
179 constructor, to parallel the warning in Moose when a superclass
180 provides its own constructor (doy)
182 0.81 Tue, April 7, 2009
185 * Class::MOP::Instance
186 * Class::MOP::Attribute
187 * Class::MOP::Method::Accessor
188 * Class::MOP::Method::Constructor
189 - Include stack traces in the deprecation warnings introduced in
190 0.80_01. (Florian Ragwitz)
193 - Avoid c compiler warnings by declaring some unused function
194 arguments. (Florian Ragwitz)
196 0.80_01 Sun, April 5, 2009
198 - Make sure to preserve any compiler flags already defined in
199 Config.pm. Patch by Vincent Pit. RT #44739.
201 * Many methods have been renamed with a leading underscore, and a
202 few have been deprecated entirely. The methods with a leading
203 underscore are consider "internals only". People writing
204 subclasses or extensions to Class::MOP should feel free to
205 override them, but they are not for "public" use.
208 - construct_class_instance => _construct_class_instance (use new_object)
209 - construct_instance => _construct_instance (use new_object)
210 - check_metaclass_compatibility => _check_metaclass_compatibility
211 - create_meta_instance => _create_meta_instance (use get_meta_instance)
212 - clone_instance => _clone_instance (use clone_object)
213 - compute_all_applicable_methods is deprecated, use get_all_methods
214 - compute_all_applicable_attributes is deprecated, use get_all_attributes
216 - Class::MOP::Instance
217 - bless_instance_structure is deprecated and will be removed
221 - create has been renamed to _instantiate_module. This method
222 does not construct an object, it evals some code that
223 creates the relevant package in Perl's symbol table.
225 - Class::MOP::Method::Accessor
226 - initialize_body => _initialize_body (this is always called
227 when an object is constructed)
228 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
230 - Class::MOP::Method::Constructor
231 - initialize_body => _initialize_body (this is always called
232 when an object is constructed)
233 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
234 - attributes => _attributes
235 - meta_instance => _meta_instance
237 0.80 Wed, April 1, 2009
239 - Call user_class->meta in fewer places, with the eventual goal
240 of allowing the user to rename or exclude ->meta
241 altogether. Instead uses Class::MOP::class_of. (Sartak)
244 - New class_of function that should be used to retrieve a
245 metaclass. This is unlike get_metaclass_by_name in that it
246 accepts instances, not just class names. (Sartak)
249 - load_first_existing_class didn't actually load the first
250 existing class; instead, it loaded the first existing and
251 compiling class. It now throws an error if a class exists (in
252 @INC) but fails to compile. (hdp)
256 - we had some semi-buggy code that purported to provide a
257 HAS_ISAREV based on whether mro had get_isarev (due to an
258 oversight, it always returned 1). Since mro and MRO::Compat
259 have always had get_isarev, HAS_ISAREV was pointless. This
260 insight simplified the subclasses method by deleting the
261 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
263 0.79 Fri, March 29, 2009
264 * No changes from 0.78_02.
266 0.78_02 Thu, March 26, 2009
268 * Class::MOP::Immutable
269 - A big backwards-incompatible refactoring of the Immutable API,
270 and the make_immutable/make_mutable pieces of the Class
271 API. The core __PACKAGE__->meta->make_immutable API remains
272 the same, however, so this should only affect the most
276 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
277 has been fixed to be backwards compatible with 5.8.x.
280 - Add a hook for rebless_instance_away (Sartak)
281 - Use blessed instead of ref to get an instance's class name
282 in rebless_instance. (Sartak)
284 0.78_01 Wed, March 18, 2009
286 - Revised and reorganized all of the API documentation. All
287 classes now have (more or less) complete API documentation.
290 * Class::MOP::Instance
291 - Reblessing into a package that supports overloading wasn't
292 properly adding overload magic to the object due to a bug
293 in (at least) 5.8.8. We now use $_[1] directly which seems
294 to set the magic properly. (Sartak)
296 * Class::MOP::Attribute
297 - The process_accessors method is now private. A public alias
298 exists (and will stick around for a few releases), but it
299 warns that calling the public method is deprecated.
301 * Class::MOP::Method::Generated
302 - Removed the new and _new methods, since this is an abstract
303 base class, and all existing subclasses implement their own
307 - Stop is_class_loaded from thinking a class is loaded if it
308 only has an empty GV (Florian Ragwitz).
309 - Add a test for this (Yappo).
310 - Refactor get_all_package_symbols to allow short-circuiting
312 - Use this in is_class_loaded (Florian Ragwitz).
313 - Stop segfaulting when trying to get the name from a sub that's
314 still being compiled (Florian Ragwitz).
315 - Add tests for this (Florian Ragwitz).
316 - Prefix all public symbols with "mop_" (Florian Ragwitz).
317 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
318 - Simplify creating simple xs reader methods (Florian Ragwitz).
319 - Make everything compile with c++ compilers (Florian Ragwitz).
320 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
323 - Remove optional test plans for tests depending on Sub::Name as
324 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
327 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
329 0.78 Mon, February 23, 2009
330 * No changes from 0.77_01
332 0.77_01 Sun, February 22, 2009
334 - This package now requires its XS components. Not using
335 Sub::Name lead to different behavior and bugginess in the pure
336 Perl version of the code. A Moose test would fail when run
337 against the pure Perl version of this code.
339 * Class::MOP::Instance
340 - The inline_* methods now quote attribute names themselves, and
341 don't expect to receive a quoted value.
344 0.77 Sat, February 14, 2009
346 - Avoid assertion errors on debugging perls in is_class_loaded
350 - Fixed various corner cases where is_class_loaded incorrectly
351 returned true for a class that wasn't really loaded. (Dave
355 - Add get_all_method_names (Sartak)
356 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
358 * Class::MOP::Package
359 - Disable deprecated get_all_package_symbols in list
360 context. (Florian Ragwitz)
363 - Make sure we generate a BSD-compatible Makefile (Florian
367 - The misspelled "check_metaclass_compatability" method we've
368 kept around for backwards compat_i_bility will be removed in a
369 near future release. You've been warned.
371 0.76 Thu, January 22, 2009
372 * Class::MOP::Method::Generated
373 - Added new private methods to support code generation, which
374 are being used by Moose and can be used by MooseX
376 - Generated methods are now generated with a #line directive
377 reflecting the source of the generated method. (nothingmuch)
380 - Clarified documentation of methods that return
381 Class::MOP::Method objects. (doy)
384 - Clarified documentation of the metaclass cache methods. (Sartak)
387 - Add test showing how the xs Class::MOP::is_class_loaded can
388 be made to operate differently to the pure perl version (t0m)
390 0.75 Wed, December 31, 2008
392 - A class that was made immutable and then mutable could end up
393 sharing an immutable transformer object
394 (Class::MOP::Immutable) with other classes, leading to all
395 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
397 0.74 Tue, December 25, 2008
399 - Add an xs implementation of Class::MOP::is_class_loaded (closes
400 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
401 - Changed internals to make prehashing of hash keys easier and less
402 error-prone. (Florian Ragwitz)
404 - Fix documentation to show that around modifiers happen on both
405 sides of the modified method. (Dave Rolsky)
407 0.73 Tue, December 16, 2008
409 - Don't use Perl_mro_meta_init. It's not part of the public perl
410 api. Fixes failures to build on Win32 (RT #41750). (Florian
412 * t/082_get_code_info.t
413 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
414 munger anonymous subs when under -d and so making the tests
415 succeed in that case.
417 0.72 Mon, December 8, 2008
418 * Class::MOP::Package
419 - Pass options to _new, so subclass' attributes can be
422 - In the docs, indicate that package_name and name are required
423 when calling ->wrap (Stefan O'Rear)
425 0.71_02 Fri, December 5, 2008
426 * Class::MOP::Immutable
427 - Added a new attribute, inlined_constructor, which is true if
428 the constructor was inlined.
429 * Class::MOP::Package
430 - Make get_all_package_symbols return a hash ref in scalar
431 context and deprecate calling it in list context with a
432 warning. (Florian Ragwitz)
434 - Various improvements and refactoring, making things more robust and
435 easier to maintain. (Florian Ragwitz)
437 0.71_01 Wed, December 3, 2008
439 - Add an "execute" method to invoke the body so
440 we can avoid using the coderef overload (Sartak)
441 * Class::MOP::Immutable
442 - When we memoize methods, get their results lazily
443 to remove some compile-time cost (Sartak)
444 - Small speedup from eliminating several method
447 - Some small internal tweaks to try to reduce the number of
448 times we call get_method_map when bootstrapping the MOP. This
449 might make loading Class::MOP (and Moose) a little
450 faster. (Dave Rolsky)
451 - Implemented an optional XS version of get_method_map. Mostly
452 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
453 help form Florian Ragwitz. (Dave Rolsky)
454 - Make the behaviour of of get_all_package_symbols (and
455 therefore get_method_map) consistent for stub methods. Report
456 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
458 0.71 Wed November 26, 2008
461 - Actual package creation has moved upward from
462 Class to Module so that Moose roles can share
465 0.70_01 Mon, November 19, 2008
467 - Fixes for failures with blead (Florian Ragwitz)
468 - Silenced compiler warnings (Florian Ragwitz)
470 0.70 Fri, November 14, 2008
472 - Fixed an odd corner case where the XS version of
473 get_all_package_symbols could cause a segfault. This only
474 happened with inlined constants in Perl 5.10.0 (Florian
477 0.69 Fri, November 7, 2008
478 * Class::MOP::Method::Wrapped
479 - Added introspection methods for method modifiers (Dave Rolsky)
482 0.68 Fri October 24, 2008
484 - Make load_class require by file name instead of module name.
485 This stops confusing error messages when loading '__PACKAGE__'.
487 - Add load_one_class_of function to enable you to load one of a
488 list of classes, rather than having to call load_class multiple
489 times in an eval. (t0m)
491 0.67 Tue October 14, 2008
493 - Call a method on the class after setting the superclass list
494 so that we can get Perl to detect cycles before MRO::Compat
495 spirals into an infinite loop (sartak)
496 - Reported by Schwern, [rt.cpan.org #39001]
497 - In create(), pass unused options on to initialize()
498 - added test for this
500 0.66 Sat September 20, 2008
501 !! This release has an incompatible change regarding !!
502 introspection of a class's method with Class::MOP::Class !!
505 - We (us maintainers) now run all tests with XS and then without
506 XS, which should help us catch skew between the XS/pure Perl
510 ! The alias_method method has been deprecated. It now simply
511 calls add_method instead. There is no distinction between
512 aliased methods and "real" methods.
514 This means that methods added via alias_method now show up as
515 part of the class's method list/map. This is a backwards
516 incompatible change, but seems unlikely to break any
517 code. Famous last words. (Dave Rolsky)
520 - Fixed the spelling of "compatibility", but we still have a
521 "check_metaclass_compatability" method for backwards
524 0.65 Mon September 1, 2008
525 For those not following the series of dev releases, the changes
526 from 0.64 from 0.65 can mostly be summed up as a lot performance
527 improvements by nothingmuch, including new optional XS versions of
528 some methods. Also, Class::MOP now works _without_ any XS modules,
529 for sad systems without a compiler.
532 - Added name and package_name XS accessors, and make sure all
533 the XS and Perl versions work the same way. (Dave Rolsky)
536 - The XS versions of various methods just returned undef when
537 called class methods, rather than dying like the pure Perl
538 versions. (Dave Rolsky)
540 0.64_07 Fri August 29, 2008
542 - Silenced warnings that managed to break Moose tests when XS
543 was loaded. (Dave Rolsky)
544 - Some XS versions of methods were ignored because of typos in
545 MOP.xs. (Dave Rolsky)
547 0.64_06 Mon August 25, 2008
548 * Class::MOP (MOP.xs)
549 - Another MS VC++ fix, cannot declare a variable in the middle
550 of a scope (Taro Nishino).
552 0.64_05 Sun August 24, 2008
554 - None of the dev releases actually loaded the XS properly, but
555 we silently fell back to the pure Perl version of the
558 * Class::MOP (MOP.xs)
559 - Replaced some code that used functions not available on Visual
560 C++ with some Perl XS API bits (Dave Rolsky).
562 0.64_04 Sat August 23, 2008
564 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
566 * pod.t and pod_coveraget.t
567 - These are no longer shipped with the tarball because of bogus
568 failures from CPAN testers. (Dave Rolsky)
570 0.64_03 Thu August 21, 2008
571 * Class::MOP::Package
572 - Some (legit) code was misparsed by earlier 5.8.x
573 releases. (nothingmuch)
576 - Fix a constant in void context warning (nothingmuch)
578 0.64_02 Thu August 21, 2008
579 * Makefile.PL and Class::MOP
580 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
583 - Add missing prereqs that got lost in the switch away from
586 * Class::MOP::Instance
587 - New method - get_all_attributes (nothingmuch)
589 0.64_01 Wed August 20, 2008
591 - We now check to see if you have a compiler. If you don't, the
592 module installs without some XS bits, but will work the same
593 as with XS. This should make it easier to install on platforms
594 without a compiler (like Windows). (Dave Rolsky)
597 - Perl 6 style attribute naming replaced with sane style ('methods', not
598 '%!methods'). These changes should not impact any existing API uses.
602 - Quite a number of optimizations based on profiling, including
603 allowing constructors to take hash references instead of
604 hashes, duplicating some frequently used code in XS, and
605 making constructors immutable. These changes should not impact
606 any existing API uses. (nothingmuch)
609 - Constructors now respect the meta attributes of their subclasses,
610 facilitating MOP extensibility. More related changes will happen in the
611 next several releases. (nothingmuch)
614 - New method - get_all_methods, replaces the deprecated
615 compute_all_applicable_methods. get_all_attributes provided for
616 consistency (nothingmuch)
617 - New method - wrap_method was refactored out of get_method_map
619 - New API for meta instance invalidation - invalidate_meta_instance,
620 invalidate_meta_instances, add_dependent_meta_instance,
621 remove_dependent_meta_instance, called automatically when attribute
622 definitions change and allows notification of dependent subclasses.
625 0.64 Sun August 3, 2008
626 * Class::MOP::Immutable
627 - fixing subtle edge case in immutable when you
629 - clean up option processing (nothingmuch)
631 * Class::MOP::Instance
632 - inlined initialize slot didn't match
633 non-inlined (nothingmuch)
635 0.63 Mon July 7, 2008
637 - load_class will initialize a metaclass even if
638 the class is already loaded (sartak)
639 - load_class now returns the metaclass instance
640 instead of just 1 (sartak)
643 - better error messages (sartak and Dave Rolsky)
645 0.62 Wed June 18, 2008
646 - in is_class_loaded, recognize scalar references (as opposed to globs) in
647 the symbol table as methods (these are optimized constant subs)
649 0.61 Fri. June 13, 2008
650 - Okay, lets give this another try and see if PAUSE
651 recognizes it correct this time.
653 0.60 Thurs. Jun 12, 2008
654 - Fixed a version number issue by bumping all modules
657 0.59 Thurs. Jun 12, 2008
658 !! Several fixes resulting in yet another 25-30% speedup !!
661 - now stores the instance of the instance
662 metaclass to avoid needless recomputation
663 and deletes it when the cache is blown
664 - introduce methods to query Class::MOP::Class for
665 the options used to make it immutable as well as
666 the proper immutable transformer. (groditi)
668 * Class::MOP::Package
669 - {add, has, get, remove}_package_symbol all
670 now accept a HASH ref argument as well as the
671 string. All internal usages now use the HASH
675 - MOP.xs does sanity checks on the coderef
677 - is_class_loaded check now uses code that
678 was improved in Moose's ClassName type
680 - nonsensical (undef, empty, reference) class
681 names now throw a more direct error in
683 - tests for this and other aspects of
689 Class::MOP::Method::Wrapped
690 Class::MOP::Attribute
691 - switched usage of reftype to ref because
694 0.58 Thurs. May 29, 2008
695 (late night release engineering)--
697 - fixing the version is META.yml, no functional
698 changes in this release
700 0.57 Wed. May 28, 2008
701 !! Several speedups resulting in 20-25% speedups !!
702 || (thanks to konobi, groditi, mst & CataMoose) !!
705 - made get_method_map use list_all_package_symbols
706 instead of manually grabbing each symbol
707 - streamlining &initialize somewhat, since it gets
710 * Class::MOP::Package
711 - made {get, has}_package_symbol not call
713 - inlining a few calls to &name with
714 direct HASH access key access
715 - added get_all_package_symbols to fetch
716 a HASH of items based on a type filter
717 similar to list_all_package_symbols
718 - added tests for this
721 Class::MOP::Method::Constructor
722 Class::MOP::Method::Generated
723 Class::MOP::Method::Accessor
724 - added more descriptive error message to help
725 keep people from wasting time tracking an error
726 that is easily fixed by upgrading.
728 * Class::MOP::Immutable
729 - Don't inline a destructor unless the user actually
731 - added tests for this
733 0.56 Saturday, May 24, 2008
735 - we now get the &check_package_cache_flag
736 function from MRO::Compat
737 - All XS based functionality now has a
738 Pure Perl alternative
739 - the CLASS_MOP_NO_XS environment variable
740 can now be used to force non-XS versions

751 - added the ability to "wrap" methods when
752 making the class immutable
755 - now handling the edge case of ->meta->identifier
756 dying by wrapping add_package_symbol to specifically
757 allow for it to work.
758 - added tests for this
760 * Class::MOP::Attribute
762 Class::MOP::Immutable
763 - any time a method meta object is constructed
764 we make sure to pass the correct package and
765 method name information
768 Class::MOP::Method::Wrapped
769 Class::MOP::Method::Generated
770 Class::MOP::Method::Accessor
771 Class::MOP::Method::Consructor
772 - the &wrap constructor method now requires that a
773 'package_name' and 'name' attribute are passed. This
774 is to help support the no-XS version, and will
775 throw an error if these are not supplied.
776 - all these classes are now bootstrapped properly
777 and now store the package_name and name attributes
780 ~ Build.PL has been removed since the
781 Module::Install support has been removed
783 0.55 Mon. April 28, 2008
784 - All classes now have proper C3 MRO support
785 - added MRO::Compat as a dependency to allow
786 for the C3 MRO support to Just Work in all
790 - rebless_instance now returns the instance
791 it has just blessed, this is mostly to
793 - set the attr correctly in rebless_instance
794 when it has no init_arg
795 - tweaked &linear_isa and &class_precedence_list
796 to support c3 classes.
798 0.54 Fri. March, 14, 2008
801 - making sure that load_class never gets
802 passed a value from @_ or $_ to squash
803 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
806 - make_{immutable,mutable} now return 1
808 - improved error handling in ->create method
809 - rebless_instance now takes extra params which
810 will be used to populate values
811 - added tests for this
814 - localizing the Data::Dumper configurations so
815 that it does not pollute others (RT #33509)
821 Class::MOP::Attribute
822 - these classes no longer define their own ->meta,
823 but instead just inherit from Class::MOP::Object
825 * Class::MOP::Instance
826 Class::MOP::Immutable
827 - these classes now inherit from Class::MOP::Object
830 - fixed the filename length on several
831 test files so we install on VMS better
833 - fixed incorrect use of catdir when it
834 should be catfile (RT #32385)

837 ~~ several doc. fixes and updates ~~
840 Class::MOP::Method::Constructor
841 Class::MOP::Attribute
842 - making init_arg accept an undefined value
843 to indicate that no constructor args can
844 be passed (thanks to nothingmuch)
845 - added tests for this
846 - added attribute initializer attribute (rjbs)
849 - making this use the new init_arg => undef
850 feature instead of the silly hack from
851 before (thanks to nothingmuch)
853 0.52 Tues. Jan. 22, 2008
855 - fixed bug in rebless_instance
858 * Class::MOP::Method::Constructor
859 - removed assumptions about the existence of
862 0.51 Mon. Jan. 14, 2008
863 ~~~ some misc. doc. fixes ~~~
864 ~~ updated copyright dates ~~
867 - now sets the IS_RUNNING_ON_5_10
868 constant so that we can take advantage
869 of some of the nice bits of 5.10
872 - uses the IS_RUNNING_ON_5_10 flag to
873 optimize the &linearized_isa method
874 and avoid the hack/check for circular
875 inheritence in &class_precedence_list
876 - added rebless_instance method (Sartak)
877 - added tests for this
879 * Class::MOP::Immutable
880 - the immutable class now keeps track of
881 the transformer which immutablized it

897 * Class::MOP::Attribute
900 0.49 Fri. Dec. 14, 2007
901 !! Class::MOP now loads 2 x faster !!
902 !! with XS speedups (thanks konobi) !!
905 - removed the dependency on B
906 - added two XS functions (thanks konobi)
907 - get_code_info($code) which replaces all
908 the B fiddling we were doing with
909 faster/leaner XS level fiddling
910 - check_package_cache_flag($pkg_name) which
911 returns the PL_sub_generation variable to
912 be used to help manage method caching.
915 In 5.10 or greater this will actually
916 use the mro::get_pkg_gen instead to give
917 even more accurate caching information.
918 blblack++ for that stuff :)
921 - added the &subclasses method (thanks rlb)
922 - added the update_package_cache_flag and
923 reset_package_cache_flag which help keep
924 track of when we need to re-fetch the
926 - Several small improvements to take advantage
927 of the new method map caching features
929 0.48 Mon. Nov. 26, 2007
930 * Class::MOP::Attribute
931 - fixed get_read/write_method to handle the

939 - added more tests for this
941 0.46 Fri. Nov. 23, 2007
943 - added the linearized_isa method instead of constantly
944 pruning duplicate classes (this will be even more
945 useful in the 5.10-compat version coming soon)
947 * Class::MOP::Attribute
948 - added the get_read_method_ref and get_write_method_ref
949 methods which allow you to retrieve a CODE ref which
950 can always be used to read or write an attribute.
952 0.45 Thurs. Nov. 13, 2007
953 * Class::MOP::Attribute
954 - Fix error message on confess (groditi)
956 0.44 Thurs. Nov. 13, 2007

959 0.43 Thurs. Nov. 13, 2007
961 - Add support for the 'builder' attribute (groditi)
964 - optimise metaclass-already-exists check in
965 construct_class_instance (groditi)
966 - duplicate check into initialize to save a
967 call through (groditi)
969 * Class::MOP::Attribute

975 - Make predicates check for the existence of a value, not whether
976 it is defined (groditi)
978 * Class::MOP::Method::Accessor
979 - made this a subclass of Class::MOP::Method::Generated
980 - removed the relevant attributes
982 * Class::MOP::Method::Constructor
983 - fixed the cached values we had to be more sane
984 - made this a subclass of Class::MOP::Method::Generated
985 - fixed generated constructor so it properly handles
987 - added tests for this
988 - added the option to allow for both inlined and
989 non-inlined constructors.
990 - Update inlined methods for builder and predicate changes (groditi)
992 * Class::MOP::Method::Generated
993 - added this class as an abstract base for the
994 Class::MOP::Method::{Constructor,Accessor} classes
995 - added tests for this
998 - Alter tests (005, 014 020, 021) for new builder addition (groditi)

1007 * Class::MOP::Package
1008 - alter symbol table handling to deal with 5.8.x and 5.9.x
1011 - Get rid of the crappy workaround from 0.40/41
1013 0.41 Sun. July 15, 2007
1015 Arghh!!! My TODO test didn't work, so I handle
1016 it manually now so that people can use this
1017 with 5.9.5/bleadperl without issue.
1019 0.40 Tues, July 3, 2007
1021 ~ marked a test in 003_methods.t as TODO
1022 for perl 5.9.5 (this test is irrelvant to
1023 the module functioning on 5.9.5 for the most
1026 0.39 Mon. June 18, 2007
1027 * Class::MOP::Immutable
1028 - added make_metaclass_mutable + docs (groditi)
1029 - removed unused variable
1030 - added create_immutable_transformer
1031 necessary for sane overloading of immutable behavior
1032 - tests for this (groditi)
1035 - Immutability can now be undone,
1036 added make_mutable + tests + docs (groditi)
1037 - Massive changes to the way Immutable is done
1038 for details see comments next to make_immutable
1039 This fixes a bug where custom metaclasses broke
1040 when made immutable. We are now keeping one immutable
1041 metaclass instance per metaclass instead of just one
1042 to prevent isa hierarchy corruption. Memory use will go
1043 up, but I suspect it will be neglible.
1044 - New tests added for this behavior. (groditi)
1046 0.38 Thurs. May 31, 2007
1047 ~~ More documentation updates ~~
1049 * Class::MOP::Package
1050 - we now deal with stub methods properly

1056 thanks to groditi for this code, tests
1058 - added tests and POD for this
1061 - fixed RT issue #27329, clone object now
1062 handles undef values correctly.
1063 - added tests for this
1064 - Corrected anon-class handling so that they
1065 will not get reaped when instances still
1066 exist which need to reference them. This is
1067 the correct behavior, hopefully this is an
1068 obscure enough feature that there are not too
1069 many work arounds out in the wild.
1070 - added tests for this by groditi
1071 - updated docs to explain this
1074 - load custom metaclasses automatically (thanks groditi)
1075 - added tests for this behavior
1077 0.37 Sat. March 10, 2007

1086 avoid setting off bool-overloads (found by Carl Franks)
1090 - bad name in a test, causing meaningless failuress.
1095 ~~ GLOBAL CHANGES ~~
1096 - All attribute names are now consistent and follow Perl 6
1097 style (prefixed with the sigil, and ! as the twigil for
1098 private attrs). This should not affect any code, unless
1099 you broke encapsulation, in which case, it is your problem
1102 !! Class::MOP::Class::Immutable has been removed
1104 * Class::MOP::Method::Constructor
1105 - this has been moved out of Class::MOP::Class::Immutable
1106 and is a proper subclass of Class::MOP::Method now.
1109 - this module now uses Class::MOP::Immutable for the
1110 immutable transformation instead of
1111 Class::MOP::Class::Immutable.
1113 + Class::MOP::Immutable
1114 - this module now controls the transformation from a mutable
1115 to an immutable version of the class. Docs for this will
1116 be coming eventually.
1119 0.36 Sun. Nov. 5, 2006
1121 - added a few 'no warnings' lines to keep annoying
1122 (and meaningless) warnings from chirping during
1126 - some more bootstrapping is now done on the new
1129 * Class::MOP::Class::Immutable
1131 - constructor generation is now handled by
1132 the Class::MOP::Method::Constructor class
1134 * Class::MOP::Method::Constructor
1135 - created this to handle constructor generation
1136 in Class::MOP::Class::Immutable
1138 * Class::MOP::Attribute
1140 - attributes now delegate to the
1141 Class::MOP::Method::Accessor to generate
1144 * Class::MOP::Method::Accessor
1145 - all accessor generation functions from
1146 Class::MOP::Attribute have been moved here

1162 - adjusted tests for this
1163 - added the Class::MOP::Instance attributes

1170 - adjusted tests to compensate
1171 - adjusted docs for this
1174 - changed how methods are dealt with to
1175 encapsulate most of the work into the
1176 &get_method_map method
1177 - made several adjustments for the change
1178 in Class::MOP::Method
1179 - &add_attribute now checks if you are adding
1180 a duplicate name, and properly removes the
1181 old one before installing the new one
1182 - added tests for this
1183 - adjusted docs for this
1185 * Class::MOP::Class::Immutable
1186 - added caching of &get_method_map
1187 - fixed issue with &get_package_symbol
1188 - cleaned up the methods that die (patch by David Wheeler)

1192 &list_all_package_symbols
1194 0.34 Sat. Aug. 26, 2006
1196 - added the %:methods attribute, which like
1197 the $:version and such just actually goes
1198 to the symbol table to get it's stuff.
1199 However, it makes the MOP more complete.
1201 - The &create method now requires that all
1202 but the package name now is passed in as
1203 named parameters. See docs for more info.
1204 - updated docs and tests for this
1206 * Class::MOP::Object
1207 - added &dump method to easily Data::Dumper

1229 are no longer allowed for defaults
1230 - added tests for this
1232 * Class::MOP::Package
1233 - fixed an issue with perl 5.8.1 and how it deals
1234 with symbol tables. The namespace hash is now
1235 always reloaded from the symbol table.
1237 ~ lots of misc. documentation cleanup
1239 0.32 Sat. Aug. 12, 2006
1240 + added Class::MOP::Object so that the
1241 metamodel is more complete (and closer
1242 to what Perl 6 will probably be).

1246 the primary gateway between the metaclass
1247 and the Perl 5 symbol table
1248 - added many tests for this
1249 - this class is now a subclass of
1251 - added some tests to reflect this

1255 use Class::MOP::Package methods instead
1257 * Class::MOP::Module
1258 - adding the $:version attribute in the bootstrap
1259 so that Module has a version as an attribute
1260 - see comment in Class::MOP for details
1261 - added the $:authority attribute to this module
1262 as well as an &identifier method, to bring us
1263 ever closer to Perl 6 goodness
1264 - I have added $AUTHORITY to all the modules
1265 - added tests for this

1284 - added &set_value and &get_value for getting
1285 the value of the attribute for a particular
1288 0.30 Wed. July 5, 2006
1289 ---------------------------------------
1290 This is the first version of Class::MOP
1291 to introduce the immutable features which
1292 will be used for optimizating the MOP.
1293 This support should still be considered
1294 experimental, but moving towards stability.
1295 ---------------------------------------
1297 * Created Class::MOP::Class::Immutable
1299 * Created the Class::MOP::Package and
1300 Class::MOP::Module classes to more
1301 closely conform to Perl 6's meta-model
1304 - now inherits from Class::MOP::Module
1305 - several methods moved to ::Module and
1306 ::Package and now inherited
1307 - added tests for this
1309 * Class::MOP::Instance
1310 - added an is_inlinable method to allow other
1311 classes to check before they attempt to optimize.
1312 - added an inline_create_instance to inline
1313 instance creation (of course)
1316 - the Class::MOP::Class::*_package_variable
1317 methods are all now methods of Class::MOP::Package
1318 and called *_package_symbol instead. This is
1319 because they are now more general purpose symbol
1320 table manipulation methods.
1322 0.29_02 Thurs. June 22, 2006
1323 ++ DEVELOPER RELEASE ++
1325 - small change in &create so that it behaves

1382 of the attribute itself, and construct_instance now
1383 delegates appropriately
1385 * Class::MOP::Attribute

1445 - &add_after_method_modifier
1446 - &add_around_method_modifier
1447 - added tests and docs for these

1469 0.10 Tues Feb. 14, 2006
1470 ** This release was mostly about writing more tests and
1471 cleaning out old and dusty code, the MOP should now
1472 be considered "ready to use".
1474 - adding more tests to get coverage up a little higher,
1475 mostly testing errors and edge cases.
1476 - test coverage is now at 99%
1479 - no longer optionally exports to UNIVERSAL::meta or
1480 creates a custom metaclass generator, use the
1481 metaclass pragma instead.
1484 - fixed a number of minor issues which came up in the
1485 error/edge-case tests
1487 * Class::MOP::Attribute
1488 - fixed a number of minor issues which came up in the
1489 error/edge-case tests
1492 - fixing the AttributesWithHistory example, it was broken.
1494 0.06 Thurs Feb. 9, 2006
1496 - adding new metaclass pragma to make setting up the
1497 metaclass a little more straightforward
1500 - clean up bootstrapping to include more complete
1501 attribute definitions for Class::MOP::Class and
1502 Class::MOP::Attribute (accessors, readers, writers,
1503 etc.) ... it is redundant, but is useful meta-info
1507 - fixing minor meta-circularity issue with &meta, it
1508 is now more useful for subclasses
1509 - added &get_attribute_map as an accessor for the
1510 hash of attribute meta objects
1511 - &compute_all_applicable_attributes now just returns
1512 the attribute meta-object, rather than the HASH ref
1513 since all the same info can be gotten from the
1514 attribute meta-object itself
1515 - updated docs & tests to reflect
1516 - added &clone_instance method which does a deep clone
1517 of the instance structure created by &construct_instance
1518 - added docs & tests for this
1519 - added Clone as a dependency
1520 - added &new_object and &clone_object convience methods to
1521 return blessed new or cloned instances
1522 - they handle Class::MOP::Class singletons correctly too
1523 - added docs & tests for this
1524 - cleaned up the &constuct_class_instance so that it behaves
1525 more like &construct_instance (and managed the singletons too)
1526 - added the &check_metaclass_compatibility method to make sure
1527 that metaclasses are upward and downward compatible.
1528 - added tests and docs for this
1531 - adjusting code to use the &Class::MOP::Class::meta
1533 - adjusting code to use the metaclass pragma
1535 0.05 Sat Feb. 4, 2006
1537 - added the &attribute_metaclass and &method_metaclass
1538 attributes which contain a metaclass name to use for
1539 attributes/methods respectively
1542 - bootstrap additional attributes for Class::MOP::Class
1545 - adjusted the example code and tests to use the new
1546 &attribute_metaclass feature of Class::MOP::Class
1547 - added new example:
1550 0.04 Fri Feb. 3, 2006
1552 - some documentation suggestions from #perl6
1554 * Class::MOP::Attribute

1562 0.03 Fri Feb. 3, 2006
1563 - converted to Module::Build instead of EU::MM
1565 * Class::MOP::Attribute
1566 - refactored method generation code
1567 - attributes are now associated with class directly
1570 - refactored the InsideOut example to take advantage
1571 of the Class::MOP::Attribute refactoring
1572 - changed example files to .pod files and hide thier
1573 package names from PAUSE (I don't want to own these
1574 namespaces really, they are just examples)
1576 0.02 Thurs Feb. 2, 2006
1577 - moving examples from t/lib/* to examples/*
