1 Revision history for Perl extension Class-MOP.
5 - Applied an MS VC++ compilation fix from Taro Nishino. RT #48072
8 - The load_class function just returns true, since it's return value was
9 confusing (either a metaclass object or a class name). It either loads
10 a class or dies trying. In the future, this may change to not return
11 anything, since there's no point in checking its return
12 value. Addresses RT #45883. (Dave Rolsky)
14 * Class::MOP::Class::Trait::Immutable
15 - When throwing an error because of an immutable method, include that
16 method's name. Addresses RT #49680. (Shawn M Moore)
19 - Fixed a bug where adding the same sub reference to multiple packages
20 failed to update the method map properly. RT #48985. Reported by Paul
22 - The get_method_map method is now private. The public version is
23 available as a deprecated method. (Dave Rolsky)
25 0.92_01 Thu, Sep 10, 2009
27 - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
30 - Make sure XS code handles magical scalars correctly. (Goro Fuji)
33 - Documented the immutable_options method, which is useful if you need
34 to make a class mutable temporarily, and then nede to restore
35 immutability. (Dave Rolsky)
38 - Deprecated features have been moved to their own module,
39 Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)
44 - Move get_method_map and its various scaffolding into Package. (hdp)
47 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
48 the first argument, rather than just a coderef. (doy)
50 * Class::MOP::Attribute
52 - Allow attribute names to be false (while still requiring them to be
56 * Class::MOP::Method::Wrapped
57 - Fixing variable usage issues with the patch from previous
58 version, not properly using lexicals in the for
62 Japan Perl Association has sponsored Goro Fuji to improve startup
63 performance of Class::MOP and Moose. These enhancements may break
64 backwards compatibility if you're doing (or using) complex
65 metaprogramming, so, as always, test your code!
66 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
70 - Anonymous classes were not completely destroyed when they went
71 out of scope, leading to a memory leak. RT #47480. (Goro
75 - The get_method, has_method, and add_method methods no longer
76 use get_method_map. Method objects are instantiated
77 lazily. This significantly improves Class::MOP's load
81 - Inline fewer metaclass-level constructors since the ones we
82 have are perfectly fine. This reduces the number of string
85 * Class::MOP::Method::Wrapped
86 - If a method modifier set $_, this caused the modifier to blow
87 up, because of some weird internals. (Jeremy Stashewsky)
91 * Class::MOP::Class::Immutable::Trait
92 - Made the Trait act like a role with a bunch of "around"
93 modifiers, rather than sticking it in the inheritance
94 hierarchy. This fixes various problems that caused with
95 metaclass compatibility, which broke Fey::ORM.
98 - Allow a blessed code reference as the method body. Fixes a
99 problem interaction with MooseX::Types. (ash)
101 * Class::MOP::Instance
102 - add inline version of rebless_instance_structure. (doy)
103 - change inline_slot_access to use single quotes (gphat)
105 0.88 Tue, Jun 23, 2009
107 - Moved the __INSTANCE__ parameter to _construct_instance from
109 - Fixed some issues involving metaclasses of metaclasses and
112 0.87 Sun, Jun 21, 2009
114 - Made sure to always local-ize $@ and $SIG{__DIE__} before
115 calling an eval. Fixes RT #45973.
118 - Synced docs about immutability with the current reality (which
119 changed back in 0.82_01)
120 - Removed the immutable_transformer method, which had been
121 returning undef since 0.82_01 anyway.
124 - Got rid of tests which needed Moose and improved testing of
125 constructor/destructor inlining warnings. Fixes RT #47119.
127 0.86 Tue, Jun 16, 2009
129 - If you redefined a subroutine at runtime and then wrapped it
130 with a method modifier, the modifier could in some cases wrap
131 the original version of the subroutine. Fixes RT #46957.
134 - make_immutable issues a warning instead of overriding an
135 existing DESTROY method (Dylan William Hardison). Fixes RT
138 0.85 Sat, Jun 6, 2009
139 * Class::MOP::Attribute
140 - Allow default values to be Class::MOP::Methods. (Florian
142 - Test the above. (Rhesa Rozendaal)
143 - Tweak original commit so the intent matches the accepted
144 behavior (Nicholas Perez)
147 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
150 - Add direct_subclasses method (Sartak)
151 - Tests for subclasses and direct_subclasses (Sartak)
152 - subname is no longer used unconditionally in add_method, but
153 only if the code reference's name is '__ANON__' (nothingmuch)
154 - Add a hook for _superclasses_updated (Sartak)
157 - Remove long, old warning about possibly outdated modules
160 0.84 Tue, May 12, 2009
162 - Depend on Text::Exception 0.27 to avoid failing tests ond old
166 - Made is_class_loaded a little stricter. It was reporting that
167 a class was loaded if it merely had an @ISA variable in its
168 stash. Now it checks that the @ISA var has elements in it.
169 - Deprecate in_global_destruction and subname re-exporting
173 - Explicitly use Devel::GlobalDestruction and Sub::Name
176 * Class::MOP::Package
177 - Disable prototype mismatch warnings for add_package_symbol.
180 - Add test for finding methods from $meta->name->meta before immutable,
183 0.83 Mon, April 27, 2009
185 - Fix segfault when calling get_method_map on a metaclass for an empty
188 0.82_02 Fri, April 24, 2009
189 * Class::MOP::Method::Inlined
190 - Don't inline if the expected method is not defined at all (happens with
191 e.g. Moose::Object::_new is the expected method due to an overridden
194 - Some tests were trying to load Class::MOP::Immutable, which
195 was removed in 0.82_01.
197 0.82_01 Thu, April 23, 2009
198 * Class::MOP::Immutable (and others)
199 - Refactor the immutability system to use a pre-defined class
200 for the immutable metaclass of Class::MOP::Class::Immutable::$class
201 - Rather than generating methods into this class every time, use
202 a Trait (basic mixin) to supply the cached methods
203 - Remove the hack that returns the mutable metaclass for
204 metacircularity in order to provide consistent meta-metaclasses
205 for the Moose compatibility handling code
206 (mst broke it, nothingmuch fixed it)
208 0.82 Mon, April 20, 2009
210 - The deprecation wrappers for some renamed methods were not
211 passing arguments to the new method. (nothingmuch)
213 * Class::MOP::Immutable
214 - Warn during immutablization if the local class provides its own
215 constructor, to parallel the warning in Moose when a superclass
216 provides its own constructor (doy)
218 0.81 Tue, April 7, 2009
221 * Class::MOP::Instance
222 * Class::MOP::Attribute
223 * Class::MOP::Method::Accessor
224 * Class::MOP::Method::Constructor
225 - Include stack traces in the deprecation warnings introduced in
226 0.80_01. (Florian Ragwitz)
229 - Avoid c compiler warnings by declaring some unused function
230 arguments. (Florian Ragwitz)
232 0.80_01 Sun, April 5, 2009
234 - Make sure to preserve any compiler flags already defined in
235 Config.pm. Patch by Vincent Pit. RT #44739.
237 * Many methods have been renamed with a leading underscore, and a
238 few have been deprecated entirely. The methods with a leading
239 underscore are consider "internals only". People writing
240 subclasses or extensions to Class::MOP should feel free to
241 override them, but they are not for "public" use.
244 - construct_class_instance => _construct_class_instance (use new_object)
245 - construct_instance => _construct_instance (use new_object)
246 - check_metaclass_compatibility => _check_metaclass_compatibility
247 - create_meta_instance => _create_meta_instance (use get_meta_instance)
248 - clone_instance => _clone_instance (use clone_object)
249 - compute_all_applicable_methods is deprecated, use get_all_methods
250 - compute_all_applicable_attributes is deprecated, use get_all_attributes
252 - Class::MOP::Instance
253 - bless_instance_structure is deprecated and will be removed
257 - create has been renamed to _instantiate_module. This method
258 does not construct an object, it evals some code that
259 creates the relevant package in Perl's symbol table.
261 - Class::MOP::Method::Accessor
262 - initialize_body => _initialize_body (this is always called
263 when an object is constructed)
264 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
266 - Class::MOP::Method::Constructor
267 - initialize_body => _initialize_body (this is always called
268 when an object is constructed)
269 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
270 - attributes => _attributes
271 - meta_instance => _meta_instance
273 0.80 Wed, April 1, 2009
275 - Call user_class->meta in fewer places, with the eventual goal
276 of allowing the user to rename or exclude ->meta
277 altogether. Instead uses Class::MOP::class_of. (Sartak)
280 - New class_of function that should be used to retrieve a
281 metaclass. This is unlike get_metaclass_by_name in that it
282 accepts instances, not just class names. (Sartak)
285 - load_first_existing_class didn't actually load the first
286 existing class; instead, it loaded the first existing and
287 compiling class. It now throws an error if a class exists (in
288 @INC) but fails to compile. (hdp)
292 - we had some semi-buggy code that purported to provide a
293 HAS_ISAREV based on whether mro had get_isarev (due to an
294 oversight, it always returned 1). Since mro and MRO::Compat
295 have always had get_isarev, HAS_ISAREV was pointless. This
296 insight simplified the subclasses method by deleting the
297 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
299 0.79 Fri, March 29, 2009
300 * No changes from 0.78_02.
302 0.78_02 Thu, March 26, 2009
304 * Class::MOP::Immutable
305 - A big backwards-incompatible refactoring of the Immutable API,
306 and the make_immutable/make_mutable pieces of the Class
307 API. The core __PACKAGE__->meta->make_immutable API remains
308 the same, however, so this should only affect the most
312 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
313 has been fixed to be backwards compatible with 5.8.x.
316 - Add a hook for rebless_instance_away (Sartak)
317 - Use blessed instead of ref to get an instance's class name
318 in rebless_instance. (Sartak)
320 0.78_01 Wed, March 18, 2009
322 - Revised and reorganized all of the API documentation. All
323 classes now have (more or less) complete API documentation.
326 * Class::MOP::Instance
327 - Reblessing into a package that supports overloading wasn't
328 properly adding overload magic to the object due to a bug
329 in (at least) 5.8.8. We now use $_[1] directly which seems
330 to set the magic properly. (Sartak)
332 * Class::MOP::Attribute
333 - The process_accessors method is now private. A public alias
334 exists (and will stick around for a few releases), but it
335 warns that calling the public method is deprecated.
337 * Class::MOP::Method::Generated
338 - Removed the new and _new methods, since this is an abstract
339 base class, and all existing subclasses implement their own
343 - Stop is_class_loaded from thinking a class is loaded if it
344 only has an empty GV (Florian Ragwitz).
345 - Add a test for this (Yappo).
346 - Refactor get_all_package_symbols to allow short-circuiting
348 - Use this in is_class_loaded (Florian Ragwitz).
349 - Stop segfaulting when trying to get the name from a sub that's
350 still being compiled (Florian Ragwitz).
351 - Add tests for this (Florian Ragwitz).
352 - Prefix all public symbols with "mop_" (Florian Ragwitz).
353 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
354 - Simplify creating simple xs reader methods (Florian Ragwitz).
355 - Make everything compile with c++ compilers (Florian Ragwitz).
356 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
359 - Remove optional test plans for tests depending on Sub::Name as
360 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
363 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
365 0.78 Mon, February 23, 2009
366 * No changes from 0.77_01
368 0.77_01 Sun, February 22, 2009
370 - This package now requires its XS components. Not using
371 Sub::Name lead to different behavior and bugginess in the pure
372 Perl version of the code. A Moose test would fail when run
373 against the pure Perl version of this code.
375 * Class::MOP::Instance
376 - The inline_* methods now quote attribute names themselves, and
377 don't expect to receive a quoted value.
380 0.77 Sat, February 14, 2009
382 - Avoid assertion errors on debugging perls in is_class_loaded
386 - Fixed various corner cases where is_class_loaded incorrectly
387 returned true for a class that wasn't really loaded. (Dave
391 - Add get_all_method_names (Sartak)
392 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
394 * Class::MOP::Package
395 - Disable deprecated get_all_package_symbols in list
396 context. (Florian Ragwitz)
399 - Make sure we generate a BSD-compatible Makefile (Florian
403 - The misspelled "check_metaclass_compatability" method we've
404 kept around for backwards compat_i_bility will be removed in a
405 near future release. You've been warned.
407 0.76 Thu, January 22, 2009
408 * Class::MOP::Method::Generated
409 - Added new private methods to support code generation, which
410 are being used by Moose and can be used by MooseX
412 - Generated methods are now generated with a #line directive
413 reflecting the source of the generated method. (nothingmuch)
416 - Clarified documentation of methods that return
417 Class::MOP::Method objects. (doy)
420 - Clarified documentation of the metaclass cache methods. (Sartak)
423 - Add test showing how the xs Class::MOP::is_class_loaded can
424 be made to operate differently to the pure perl version (t0m)
426 0.75 Wed, December 31, 2008
428 - A class that was made immutable and then mutable could end up
429 sharing an immutable transformer object
430 (Class::MOP::Immutable) with other classes, leading to all
431 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
433 0.74 Tue, December 25, 2008
435 - Add an xs implementation of Class::MOP::is_class_loaded (closes
436 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
437 - Changed internals to make prehashing of hash keys easier and less
438 error-prone. (Florian Ragwitz)
440 - Fix documentation to show that around modifiers happen on both
441 sides of the modified method. (Dave Rolsky)
443 0.73 Tue, December 16, 2008
445 - Don't use Perl_mro_meta_init. It's not part of the public perl
446 api. Fixes failures to build on Win32 (RT #41750). (Florian
448 * t/082_get_code_info.t
449 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
450 munger anonymous subs when under -d and so making the tests
451 succeed in that case.
453 0.72 Mon, December 8, 2008
454 * Class::MOP::Package
455 - Pass options to _new, so subclass' attributes can be
458 - In the docs, indicate that package_name and name are required
459 when calling ->wrap (Stefan O'Rear)
461 0.71_02 Fri, December 5, 2008
462 * Class::MOP::Immutable
463 - Added a new attribute, inlined_constructor, which is true if
464 the constructor was inlined.
465 * Class::MOP::Package
466 - Make get_all_package_symbols return a hash ref in scalar
467 context and deprecate calling it in list context with a
468 warning. (Florian Ragwitz)
470 - Various improvements and refactoring, making things more robust and
471 easier to maintain. (Florian Ragwitz)
473 0.71_01 Wed, December 3, 2008
475 - Add an "execute" method to invoke the body so
476 we can avoid using the coderef overload (Sartak)
477 * Class::MOP::Immutable
478 - When we memoize methods, get their results lazily
479 to remove some compile-time cost (Sartak)
480 - Small speedup from eliminating several method
483 - Some small internal tweaks to try to reduce the number of
484 times we call get_method_map when bootstrapping the MOP. This
485 might make loading Class::MOP (and Moose) a little
486 faster. (Dave Rolsky)
487 - Implemented an optional XS version of get_method_map. Mostly
488 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
489 help form Florian Ragwitz. (Dave Rolsky)
490 - Make the behaviour of of get_all_package_symbols (and
491 therefore get_method_map) consistent for stub methods. Report
492 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
494 0.71 Wed November 26, 2008
497 - Actual package creation has moved upward from
498 Class to Module so that Moose roles can share
501 0.70_01 Mon, November 19, 2008
503 - Fixes for failures with blead (Florian Ragwitz)
504 - Silenced compiler warnings (Florian Ragwitz)
506 0.70 Fri, November 14, 2008
508 - Fixed an odd corner case where the XS version of
509 get_all_package_symbols could cause a segfault. This only
510 happened with inlined constants in Perl 5.10.0 (Florian
513 0.69 Fri, November 7, 2008
514 * Class::MOP::Method::Wrapped
515 - Added introspection methods for method modifiers (Dave Rolsky)
518 0.68 Fri October 24, 2008
520 - Make load_class require by file name instead of module name.
521 This stops confusing error messages when loading '__PACKAGE__'.
523 - Add load_one_class_of function to enable you to load one of a
524 list of classes, rather than having to call load_class multiple
525 times in an eval. (t0m)
527 0.67 Tue October 14, 2008
529 - Call a method on the class after setting the superclass list
530 so that we can get Perl to detect cycles before MRO::Compat
531 spirals into an infinite loop (sartak)
532 - Reported by Schwern, [rt.cpan.org #39001]
533 - In create(), pass unused options on to initialize()
534 - added test for this
536 0.66 Sat September 20, 2008
537 !! This release has an incompatible change regarding !!
538 introspection of a class's method with Class::MOP::Class !!
541 - We (us maintainers) now run all tests with XS and then without
542 XS, which should help us catch skew between the XS/pure Perl
546 ! The alias_method method has been deprecated. It now simply
547 calls add_method instead. There is no distinction between
548 aliased methods and "real" methods.
550 This means that methods added via alias_method now show up as
551 part of the class's method list/map. This is a backwards
552 incompatible change, but seems unlikely to break any
553 code. Famous last words. (Dave Rolsky)
556 - Fixed the spelling of "compatibility", but we still have a
557 "check_metaclass_compatability" method for backwards
560 0.65 Mon September 1, 2008
561 For those not following the series of dev releases, the changes
562 from 0.64 from 0.65 can mostly be summed up as a lot performance
563 improvements by nothingmuch, including new optional XS versions of
564 some methods. Also, Class::MOP now works _without_ any XS modules,
565 for sad systems without a compiler.
568 - Added name and package_name XS accessors, and make sure all
569 the XS and Perl versions work the same way. (Dave Rolsky)
572 - The XS versions of various methods just returned undef when
573 called class methods, rather than dying like the pure Perl
574 versions. (Dave Rolsky)
576 0.64_07 Fri August 29, 2008
578 - Silenced warnings that managed to break Moose tests when XS
579 was loaded. (Dave Rolsky)
580 - Some XS versions of methods were ignored because of typos in
581 MOP.xs. (Dave Rolsky)
583 0.64_06 Mon August 25, 2008
584 * Class::MOP (MOP.xs)
585 - Another MS VC++ fix, cannot declare a variable in the middle
586 of a scope (Taro Nishino).
588 0.64_05 Sun August 24, 2008
590 - None of the dev releases actually loaded the XS properly, but
591 we silently fell back to the pure Perl version of the
594 * Class::MOP (MOP.xs)
595 - Replaced some code that used functions not available on Visual
596 C++ with some Perl XS API bits (Dave Rolsky).
598 0.64_04 Sat August 23, 2008
600 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
602 * pod.t and pod_coveraget.t
603 - These are no longer shipped with the tarball because of bogus
604 failures from CPAN testers. (Dave Rolsky)
606 0.64_03 Thu August 21, 2008
607 * Class::MOP::Package
608 - Some (legit) code was misparsed by earlier 5.8.x
609 releases. (nothingmuch)
612 - Fix a constant in void context warning (nothingmuch)
614 0.64_02 Thu August 21, 2008
615 * Makefile.PL and Class::MOP
616 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
619 - Add missing prereqs that got lost in the switch away from
622 * Class::MOP::Instance
623 - New method - get_all_attributes (nothingmuch)
625 0.64_01 Wed August 20, 2008
627 - We now check to see if you have a compiler. If you don't, the
628 module installs without some XS bits, but will work the same
629 as with XS. This should make it easier to install on platforms
630 without a compiler (like Windows). (Dave Rolsky)
633 - Perl 6 style attribute naming replaced with sane style ('methods', not
634 '%!methods'). These changes should not impact any existing API uses.
638 - Quite a number of optimizations based on profiling, including
639 allowing constructors to take hash references instead of
640 hashes, duplicating some frequently used code in XS, and
641 making constructors immutable. These changes should not impact
642 any existing API uses. (nothingmuch)
645 - Constructors now respect the meta attributes of their subclasses,
646 facilitating MOP extensibility. More related changes will happen in the
647 next several releases. (nothingmuch)
650 - New method - get_all_methods, replaces the deprecated
651 compute_all_applicable_methods. get_all_attributes provided for
652 consistency (nothingmuch)
653 - New method - wrap_method was refactored out of get_method_map
655 - New API for meta instance invalidation - invalidate_meta_instance,
656 invalidate_meta_instances, add_dependent_meta_instance,
657 remove_dependent_meta_instance, called automatically when attribute
658 definitions change and allows notification of dependent subclasses.
661 0.64 Sun August 3, 2008
662 * Class::MOP::Immutable
663 - fixing subtle edge case in immutable when you
665 - clean up option processing (nothingmuch)
667 * Class::MOP::Instance
668 - inlined initialize slot didn't match
669 non-inlined (nothingmuch)
671 0.63 Mon July 7, 2008
673 - load_class will initialize a metaclass even if
674 the class is already loaded (sartak)
675 - load_class now returns the metaclass instance
676 instead of just 1 (sartak)
679 - better error messages (sartak and Dave Rolsky)
681 0.62 Wed June 18, 2008
682 - in is_class_loaded, recognize scalar references (as opposed to globs) in
683 the symbol table as methods (these are optimized constant subs)
685 0.61 Fri. June 13, 2008
686 - Okay, lets give this another try and see if PAUSE
687 recognizes it correct this time.
689 0.60 Thurs. Jun 12, 2008
690 - Fixed a version number issue by bumping all modules
693 0.59 Thurs. Jun 12, 2008
694 !! Several fixes resulting in yet another 25-30% speedup !!
697 - now stores the instance of the instance
698 metaclass to avoid needless recomputation
699 and deletes it when the cache is blown
700 - introduce methods to query Class::MOP::Class for
701 the options used to make it immutable as well as
702 the proper immutable transformer. (groditi)
704 * Class::MOP::Package
705 - {add, has, get, remove}_package_symbol all
706 now accept a HASH ref argument as well as the
707 string. All internal usages now use the HASH
711 - MOP.xs does sanity checks on the coderef
713 - is_class_loaded check now uses code that
714 was improved in Moose's ClassName type
716 - nonsensical (undef, empty, reference) class
717 names now throw a more direct error in
719 - tests for this and other aspects of
725 Class::MOP::Method::Wrapped
726 Class::MOP::Attribute
727 - switched usage of reftype to ref because
730 0.58 Thurs. May 29, 2008
731 (late night release engineering)--
733 - fixing the version is META.yml, no functional
734 changes in this release
736 0.57 Wed. May 28, 2008
737 !! Several speedups resulting in 20-25% speedups !!
738 || (thanks to konobi, groditi, mst & CataMoose) !!
741 - made get_method_map use list_all_package_symbols
742 instead of manually grabbing each symbol
743 - streamlining &initialize somewhat, since it gets
746 * Class::MOP::Package
747 - made {get, has}_package_symbol not call
749 - inlining a few calls to &name with
750 direct HASH access key access
751 - added get_all_package_symbols to fetch
752 a HASH of items based on a type filter
753 similar to list_all_package_symbols
754 - added tests for this
757 Class::MOP::Method::Constructor
758 Class::MOP::Method::Generated
759 Class::MOP::Method::Accessor
760 - added more descriptive error message to help
761 keep people from wasting time tracking an error
762 that is easily fixed by upgrading.
764 * Class::MOP::Immutable
765 - Don't inline a destructor unless the user actually
767 - added tests for this
769 0.56 Saturday, May 24, 2008
771 - we now get the &check_package_cache_flag
772 function from MRO::Compat
773 - All XS based functionality now has a
774 Pure Perl alternative
775 - the CLASS_MOP_NO_XS environment variable
776 can now be used to force non-XS versions

782 anon-sub ref in the method metaclass when
784 - added tests for this
786 * Class::MOP::Immutable
787 - added the ability to "wrap" methods when
788 making the class immutable
791 - now handling the edge case of ->meta->identifier
792 dying by wrapping add_package_symbol to specifically
793 allow for it to work.
794 - added tests for this
796 * Class::MOP::Attribute
798 Class::MOP::Immutable
799 - any time a method meta object is constructed
800 we make sure to pass the correct package and
801 method name information
804 Class::MOP::Method::Wrapped
805 Class::MOP::Method::Generated
806 Class::MOP::Method::Accessor
807 Class::MOP::Method::Consructor
808 - the &wrap constructor method now requires that a
809 'package_name' and 'name' attribute are passed. This
810 is to help support the no-XS version, and will
811 throw an error if these are not supplied.
812 - all these classes are now bootstrapped properly
813 and now store the package_name and name attributes
816 ~ Build.PL has been removed since the
817 Module::Install support has been removed
819 0.55 Mon. April 28, 2008
820 - All classes now have proper C3 MRO support
821 - added MRO::Compat as a dependency to allow
822 for the C3 MRO support to Just Work in all
826 - rebless_instance now returns the instance
827 it has just blessed, this is mostly to
829 - set the attr correctly in rebless_instance
830 when it has no init_arg
831 - tweaked &linear_isa and &class_precedence_list
832 to support c3 classes.
834 0.54 Fri. March, 14, 2008
837 - making sure that load_class never gets
838 passed a value from @_ or $_ to squash
839 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
842 - make_{immutable,mutable} now return 1
844 - improved error handling in ->create method
845 - rebless_instance now takes extra params which
846 will be used to populate values
847 - added tests for this
850 - localizing the Data::Dumper configurations so
851 that it does not pollute others (RT #33509)
857 Class::MOP::Attribute
858 - these classes no longer define their own ->meta,
859 but instead just inherit from Class::MOP::Object
861 * Class::MOP::Instance
862 Class::MOP::Immutable
863 - these classes now inherit from Class::MOP::Object
866 - fixed the filename length on several
867 test files so we install on VMS better
869 - fixed incorrect use of catdir when it
870 should be catfile (RT #32385)
872 0.53 Thurs. Feb. 14, 1008
873 ~~ several doc. fixes and updates ~~
876 Class::MOP::Method::Constructor

879 to indicate that no constructor args can
880 be passed (thanks to nothingmuch)
881 - added tests for this
882 - added attribute initializer attribute (rjbs)
885 - making this use the new init_arg => undef
886 feature instead of the silly hack from
887 before (thanks to nothingmuch)
889 0.52 Tues. Jan. 22, 2008
891 - fixed bug in rebless_instance
894 * Class::MOP::Method::Constructor
895 - removed assumptions about the existence of
898 0.51 Mon. Jan. 14, 2008
899 ~~~ some misc. doc. fixes ~~~
900 ~~ updated copyright dates ~~
903 - now sets the IS_RUNNING_ON_5_10
904 constant so that we can take advantage
905 of some of the nice bits of 5.10
908 - uses the IS_RUNNING_ON_5_10 flag to
909 optimize the &linearized_isa method
910 and avoid the hack/check for circular
911 inheritence in &class_precedence_list
912 - added rebless_instance method (Sartak)
913 - added tests for this
915 * Class::MOP::Immutable
916 - the immutable class now keeps track of
917 the transformer which immutablized it
919 * Class::MOP::Instance
920 - added rebless_instance_structure method (Sartak)
921 - added tests for this
923 0.50 Fri. Dec. 21, 2007

933 * Class::MOP::Attribute
936 0.49 Fri. Dec. 14, 2007
937 !! Class::MOP now loads 2 x faster !!
938 !! with XS speedups (thanks konobi) !!
941 - removed the dependency on B
942 - added two XS functions (thanks konobi)
943 - get_code_info($code) which replaces all
944 the B fiddling we were doing with
945 faster/leaner XS level fiddling
946 - check_package_cache_flag($pkg_name) which
947 returns the PL_sub_generation variable to
948 be used to help manage method caching.
951 In 5.10 or greater this will actually
952 use the mro::get_pkg_gen instead to give
953 even more accurate caching information.
954 blblack++ for that stuff :)
957 - added the &subclasses method (thanks rlb)
958 - added the update_package_cache_flag and
959 reset_package_cache_flag which help keep
960 track of when we need to re-fetch the
962 - Several small improvements to take advantage
963 of the new method map caching features
965 0.48 Mon. Nov. 26, 2007
966 * Class::MOP::Attribute
967 - fixed get_read/write_method to handle the
968 HASH ref case, which makes the

970 - added more tests for this
972 0.47 Sat. Nov. 24, 2007
973 * Class::MOP::Attribute

975 - added more tests for this
977 0.46 Fri. Nov. 23, 2007
979 - added the linearized_isa method instead of constantly
980 pruning duplicate classes (this will be even more
981 useful in the 5.10-compat version coming soon)
983 * Class::MOP::Attribute
984 - added the get_read_method_ref and get_write_method_ref
985 methods which allow you to retrieve a CODE ref which
986 can always be used to read or write an attribute.
988 0.45 Thurs. Nov. 13, 2007
989 * Class::MOP::Attribute
990 - Fix error message on confess (groditi)
992 0.44 Thurs. Nov. 13, 2007

1003 call through (groditi)
1005 * Class::MOP::Attribute
1006 - Add support for the 'builder' attribute (groditi)

1016 - removed the relevant attributes
1018 * Class::MOP::Method::Constructor
1019 - fixed the cached values we had to be more sane
1020 - made this a subclass of Class::MOP::Method::Generated
1021 - fixed generated constructor so it properly handles
1023 - added tests for this
1024 - added the option to allow for both inlined and
1025 non-inlined constructors.
1026 - Update inlined methods for builder and predicate changes (groditi)
1028 * Class::MOP::Method::Generated
1029 - added this class as an abstract base for the
1030 Class::MOP::Method::{Constructor,Accessor} classes
1031 - added tests for this

1044 - alter symbol table handling to deal with 5.8.x and 5.9.x
1047 - Get rid of the crappy workaround from 0.40/41
1049 0.41 Sun. July 15, 2007
1051 Arghh!!! My TODO test didn't work, so I handle
1052 it manually now so that people can use this
1053 with 5.9.5/bleadperl without issue.
1055 0.40 Tues, July 3, 2007
1057 ~ marked a test in 003_methods.t as TODO
1058 for perl 5.9.5 (this test is irrelvant to
1059 the module functioning on 5.9.5 for the most
1062 0.39 Mon. June 18, 2007
1063 * Class::MOP::Immutable
1064 - added make_metaclass_mutable + docs (groditi)
1065 - removed unused variable
1066 - added create_immutable_transformer
1067 necessary for sane overloading of immutable behavior
1068 - tests for this (groditi)
1071 - Immutability can now be undone,
1072 added make_mutable + tests + docs (groditi)
1073 - Massive changes to the way Immutable is done
1074 for details see comments next to make_immutable
1075 This fixes a bug where custom metaclasses broke
1076 when made immutable. We are now keeping one immutable
1077 metaclass instance per metaclass instead of just one
1078 to prevent isa hierarchy corruption. Memory use will go
1079 up, but I suspect it will be neglible.
1080 - New tests added for this behavior. (groditi)
1082 0.38 Thurs. May 31, 2007
1083 ~~ More documentation updates ~~
1085 * Class::MOP::Package
1086 - we now deal with stub methods properly

1088 - fixed some tests failing on 5.9.5 (thanks blblack)
1090 * Class::MOP::Attribute
1091 - added get_read_method and get_write_method
1092 thanks to groditi for this code, tests
1094 - added tests and POD for this
1097 - fixed RT issue #27329, clone object now
1098 handles undef values correctly.
1099 - added tests for this
1100 - Corrected anon-class handling so that they
1101 will not get reaped when instances still
1102 exist which need to reference them. This is
1103 the correct behavior, hopefully this is an
1104 obscure enough feature that there are not too
1105 many work arounds out in the wild.
1106 - added tests for this by groditi
1107 - updated docs to explain this
1110 - load custom metaclasses automatically (thanks groditi)
1111 - added tests for this behavior
1113 0.37 Sat. March 10, 2007
1114 ~~ Many, many documentation updates ~~
1117 - added &load_class and &is_class_loaded

1120 * Class::MOP::Attribute
1121 - default now checks the instance with defined to
1122 avoid setting off bool-overloads (found by Carl Franks)
1126 - bad name in a test, causing meaningless failuress.
1131 ~~ GLOBAL CHANGES ~~
1132 - All attribute names are now consistent and follow Perl 6
1133 style (prefixed with the sigil, and ! as the twigil for
1134 private attrs). This should not affect any code, unless
1135 you broke encapsulation, in which case, it is your problem
1138 !! Class::MOP::Class::Immutable has been removed
1140 * Class::MOP::Method::Constructor
1141 - this has been moved out of Class::MOP::Class::Immutable
1142 and is a proper subclass of Class::MOP::Method now.
1145 - this module now uses Class::MOP::Immutable for the
1146 immutable transformation instead of
1147 Class::MOP::Class::Immutable.
1149 + Class::MOP::Immutable
1150 - this module now controls the transformation from a mutable
1151 to an immutable version of the class. Docs for this will
1152 be coming eventually.
1155 0.36 Sun. Nov. 5, 2006
1157 - added a few 'no warnings' lines to keep annoying
1158 (and meaningless) warnings from chirping during
1162 - some more bootstrapping is now done on the new
1165 * Class::MOP::Class::Immutable
1167 - constructor generation is now handled by
1168 the Class::MOP::Method::Constructor class
1170 * Class::MOP::Method::Constructor
1171 - created this to handle constructor generation
1172 in Class::MOP::Class::Immutable
1174 * Class::MOP::Attribute
1176 - attributes now delegate to the
1177 Class::MOP::Method::Accessor to generate
1180 * Class::MOP::Method::Accessor
1181 - all accessor generation functions from
1182 Class::MOP::Attribute have been moved here
1184 0.35 Sat. Sept. 30, 2006
1186 * scripts/class_browser.pl
1187 - initial prototype of a class browser, more
1188 on this to come. Comments and patches are
1192 - All Class::MOP::* accessors are no longer
1193 re-generated in the bootstrap, instead
1194 they are aliased from the originals
1195 - fixed tests to reflect
1196 - added Class::MOP::Method (and its subclasses)
1198 - adjusted tests for this
1199 - added the Class::MOP::Instance attributes

1206 - adjusted tests to compensate
1207 - adjusted docs for this
1210 - changed how methods are dealt with to
1211 encapsulate most of the work into the
1212 &get_method_map method
1213 - made several adjustments for the change
1214 in Class::MOP::Method
1215 - &add_attribute now checks if you are adding
1216 a duplicate name, and properly removes the
1217 old one before installing the new one
1218 - added tests for this
1219 - adjusted docs for this
1221 * Class::MOP::Class::Immutable
1222 - added caching of &get_method_map
1223 - fixed issue with &get_package_symbol
1224 - cleaned up the methods that die (patch by David Wheeler)

1227 - added filtering capabilities to
1228 &list_all_package_symbols
1230 0.34 Sat. Aug. 26, 2006
1232 - added the %:methods attribute, which like
1233 the $:version and such just actually goes
1234 to the symbol table to get it's stuff.
1235 However, it makes the MOP more complete.
1237 - The &create method now requires that all
1238 but the package name now is passed in as
1239 named parameters. See docs for more info.
1240 - updated docs and tests for this
1242 * Class::MOP::Object
1243 - added &dump method to easily Data::Dumper

1264 - reference values (other than CODE refs)
1265 are no longer allowed for defaults
1266 - added tests for this
1268 * Class::MOP::Package
1269 - fixed an issue with perl 5.8.1 and how it deals
1270 with symbol tables. The namespace hash is now
1271 always reloaded from the symbol table.
1273 ~ lots of misc. documentation cleanup
1275 0.32 Sat. Aug. 12, 2006
1276 + added Class::MOP::Object so that the
1277 metamodel is more complete (and closer
1278 to what Perl 6 will probably be).

1282 the primary gateway between the metaclass
1283 and the Perl 5 symbol table
1284 - added many tests for this
1285 - this class is now a subclass of
1287 - added some tests to reflect this

1291 use Class::MOP::Package methods instead
1293 * Class::MOP::Module
1294 - adding the $:version attribute in the bootstrap
1295 so that Module has a version as an attribute
1296 - see comment in Class::MOP for details
1297 - added the $:authority attribute to this module
1298 as well as an &identifier method, to bring us
1299 ever closer to Perl 6 goodness
1300 - I have added $AUTHORITY to all the modules
1301 - added tests for this

1317 anywhere within the class hierarchy
1319 * Class::MOP::Attribute
1320 - added &set_value and &get_value for getting
1321 the value of the attribute for a particular
1324 0.30 Wed. July 5, 2006
1325 ---------------------------------------
1326 This is the first version of Class::MOP
1327 to introduce the immutable features which
1328 will be used for optimizating the MOP.
1329 This support should still be considered
1330 experimental, but moving towards stability.
1331 ---------------------------------------
1333 * Created Class::MOP::Class::Immutable
1335 * Created the Class::MOP::Package and
1336 Class::MOP::Module classes to more
1337 closely conform to Perl 6's meta-model
1340 - now inherits from Class::MOP::Module
1341 - several methods moved to ::Module and
1342 ::Package and now inherited
1343 - added tests for this
1345 * Class::MOP::Instance
1346 - added an is_inlinable method to allow other
1347 classes to check before they attempt to optimize.
1348 - added an inline_create_instance to inline
1349 instance creation (of course)
1352 - the Class::MOP::Class::*_package_variable
1353 methods are all now methods of Class::MOP::Package
1354 and called *_package_symbol instead. This is
1355 because they are now more general purpose symbol
1356 table manipulation methods.
1358 0.29_02 Thurs. June 22, 2006
1359 ++ DEVELOPER RELEASE ++
1361 - small change in &create so that it behaves

1366 ++ DEVELOPER RELEASE ++
1367 - This release works in combination with
1368 Moose 0.09_01, it is a developer release

1413 - added tests for this
1414 - added get_all_metaclasses, get_all_metaclass_names
1415 and get_all_metaclass_instances method to allow
1416 access to all the cached metaclass objects.
1417 - attribute slot initialization is now the responsibility
1418 of the attribute itself, and construct_instance now
1419 delegates appropriately
1421 * Class::MOP::Attribute

1423 of the attribute itself, so we added a method for it
1424 called initialize_instance_slot

1437 - fixed the way attribute defaults are handled
1438 during instance construction (bug found by chansen)
1440 * Class::MOP::Attribute
1441 - read-only accessors ('reader') will now die if
1442 passed more than one argument (attempting to write

1451 - added test case for this
1453 0.21 Wed. March 15, 2006
1455 - fixed issue where metaclasses are reaped from
1456 our cache in global destruction, and so are not
1457 available in DESTORY calls
1459 0.20 Thurs. March 2, 2006
1460 - removed the dependency for Clone since
1461 we no longer to deep-cloning by default.
1463 * Class::MOP::Method
1464 - added &package_name, &name and
1465 &fully_qualified_name methods, some of
1466 which were formerly private subs in
1469 * Class::MOP::Method::Wrapped
1470 - allows for a method to be wrapped with
1471 before, after and around modifiers
1472 - added tests and docs for this feature
1475 - improved &get_package_symbol
1476 - &version and &superclasses now use it
1477 - methods are now blessed into Class::MOP::Method
1479 - added methods to install CLOS-style method modifiers
1480 - &add_before_method_modifier
1481 - &add_after_method_modifier
1482 - &add_around_method_modifier
1483 - added tests and docs for these
1484 - added &find_next_method_by_name which finds the
1485 equivalent of SUPER::method_name
1487 0.12 Thurs. Feb 23, 2006
1488 - reduced the dependency on B, no need to always
1492 - added docs to the C3 method dispatch order test
1493 - fixed missing Algorithm::C3 dependency by making
1494 the test skip if it is not installed
1496 0.11 Mon Feb. 20, 2006
1498 - added example of changing method dispatch order to C3
1501 - changed how clone_instance behaves, it now only does a
1502 shallow clone (see docs for more details)
1503 - added docs and tests
1505 0.10 Tues Feb. 14, 2006
1506 ** This release was mostly about writing more tests and
1507 cleaning out old and dusty code, the MOP should now
1508 be considered "ready to use".
1510 - adding more tests to get coverage up a little higher,
1511 mostly testing errors and edge cases.
1512 - test coverage is now at 99%
1515 - no longer optionally exports to UNIVERSAL::meta or
1516 creates a custom metaclass generator, use the
1517 metaclass pragma instead.
1520 - fixed a number of minor issues which came up in the
1521 error/edge-case tests
1523 * Class::MOP::Attribute
1524 - fixed a number of minor issues which came up in the
1525 error/edge-case tests
1528 - fixing the AttributesWithHistory example, it was broken.
1530 0.06 Thurs Feb. 9, 2006
1532 - adding new metaclass pragma to make setting up the
1533 metaclass a little more straightforward
1536 - clean up bootstrapping to include more complete
1537 attribute definitions for Class::MOP::Class and
1538 Class::MOP::Attribute (accessors, readers, writers,
1539 etc.) ... it is redundant, but is useful meta-info
1543 - fixing minor meta-circularity issue with &meta, it
1544 is now more useful for subclasses
1545 - added &get_attribute_map as an accessor for the
1546 hash of attribute meta objects
1547 - &compute_all_applicable_attributes now just returns
1548 the attribute meta-object, rather than the HASH ref
1549 since all the same info can be gotten from the
1550 attribute meta-object itself
1551 - updated docs & tests to reflect
1552 - added &clone_instance method which does a deep clone
1553 of the instance structure created by &construct_instance
1554 - added docs & tests for this
1555 - added Clone as a dependency
1556 - added &new_object and &clone_object convience methods to
1557 return blessed new or cloned instances
1558 - they handle Class::MOP::Class singletons correctly too
1559 - added docs & tests for this
1560 - cleaned up the &constuct_class_instance so that it behaves
1561 more like &construct_instance (and managed the singletons too)
1562 - added the &check_metaclass_compatibility method to make sure
1563 that metaclasses are upward and downward compatible.
1564 - added tests and docs for this
1567 - adjusting code to use the &Class::MOP::Class::meta
1569 - adjusting code to use the metaclass pragma
1571 0.05 Sat Feb. 4, 2006
1573 - added the &attribute_metaclass and &method_metaclass
1574 attributes which contain a metaclass name to use for
1575 attributes/methods respectively
1578 - bootstrap additional attributes for Class::MOP::Class
1581 - adjusted the example code and tests to use the new
1582 &attribute_metaclass feature of Class::MOP::Class
1583 - added new example:
1586 0.04 Fri Feb. 3, 2006
1588 - some documentation suggestions from #perl6
1590 * Class::MOP::Attribute
1591 - improved error messages

1606 - refactored the InsideOut example to take advantage
1607 of the Class::MOP::Attribute refactoring
1608 - changed example files to .pod files and hide thier
1609 package names from PAUSE (I don't want to own these
1610 namespaces really, they are just examples)
1612 0.02 Thurs Feb. 2, 2006
1613 - moving examples from t/lib/* to examples/*
1614 - adding POD documentation to the examples
