1 Revision history for Perl extension Class-MOP.
4 - Make is_class_loaded without any arguments fail loudly
6 - Make load_class throw more standard error messages when loading single
10 - Stop add_method from behaving differently under the debugger
15 - Any method which takes a method name as an argument now allows names
16 which are false (like "0"), but the name must be defined and not be an
17 empty string. (Dave Rolsky)
20 - Deprecated get_attribute_map as a public method. You can use a
21 combination of get_attribute_list and get_attribute instead. (Dave
24 0.94 Tue, Sep 22, 2009
25 * Class::MOP::Attribute
26 - Introduce set_raw_value and get_raw_value, side effect free variants
27 of {get,set}_value. These don't do anything useful in Class::MOP but
28 have different behavior that set_value and get_value for Moose
29 attributes. (nothingmuch)
31 0.93 Tue, Sep 15, 2009
33 - The load_class function just returns true, since it's return value was
34 confusing (either a metaclass object or a class name). It either loads
35 a class or dies trying. In the future, this may change to not return
36 anything, since there's no point in checking its return
37 value. Addresses RT #45883. (Dave Rolsky)
39 * Class::MOP::Class::Trait::Immutable
40 - When throwing an error because of an immutable method, include that
41 method's name. Addresses RT #49680. (Shawn M Moore)
44 - Adding the same sub reference to multiple packages failed to update
45 the method map properly. RT #48985. Reported by Paul Mooney. (Dave
47 - The get_method_map method is now private (and called as
48 _full_method_map or _method_map). The public version is available as a
49 deprecated method. (Dave Rolsky)
51 0.92_01 Thu, Sep 10, 2009
53 - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
56 - Make sure XS code handles magical scalars correctly. (Goro Fuji)
59 - Documented the immutable_options method, which is useful if you need
60 to make a class mutable temporarily, and then nede to restore
61 immutability. (Dave Rolsky)
64 - Deprecated features have been moved to their own module,
65 Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)
70 - Move get_method_map and its various scaffolding into Package. (hdp)
73 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
74 the first argument, rather than just a coderef. (doy)
76 * Class::MOP::Attribute
78 - Allow attribute names to be false (while still requiring them to be
82 * Class::MOP::Method::Wrapped
83 - Fixing variable usage issues with the patch from previous
84 version, not properly using lexicals in the for
88 Japan Perl Association has sponsored Goro Fuji to improve startup
89 performance of Class::MOP and Moose. These enhancements may break
90 backwards compatibility if you're doing (or using) complex
91 metaprogramming, so, as always, test your code!
92 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
96 - Anonymous classes were not completely destroyed when they went
97 out of scope, leading to a memory leak. RT #47480. (Goro
101 - The get_method, has_method, and add_method methods no longer
102 use get_method_map. Method objects are instantiated
103 lazily. This significantly improves Class::MOP's load
107 - Inline fewer metaclass-level constructors since the ones we
108 have are perfectly fine. This reduces the number of string
111 * Class::MOP::Method::Wrapped
112 - If a method modifier set $_, this caused the modifier to blow
113 up, because of some weird internals. (Jeremy Stashewsky)
117 * Class::MOP::Class::Immutable::Trait
118 - Made the Trait act like a role with a bunch of "around"
119 modifiers, rather than sticking it in the inheritance
120 hierarchy. This fixes various problems that caused with
121 metaclass compatibility, which broke Fey::ORM.
124 - Allow a blessed code reference as the method body. Fixes a
125 problem interaction with MooseX::Types. (ash)
127 * Class::MOP::Instance
128 - add inline version of rebless_instance_structure. (doy)
129 - change inline_slot_access to use single quotes (gphat)
131 0.88 Tue, Jun 23, 2009
133 - Moved the __INSTANCE__ parameter to _construct_instance from
135 - Fixed some issues involving metaclasses of metaclasses and
138 0.87 Sun, Jun 21, 2009
140 - Made sure to always local-ize $@ and $SIG{__DIE__} before
141 calling an eval. Fixes RT #45973.
144 - Synced docs about immutability with the current reality (which
145 changed back in 0.82_01)
146 - Removed the immutable_transformer method, which had been
147 returning undef since 0.82_01 anyway.
150 - Got rid of tests which needed Moose and improved testing of
151 constructor/destructor inlining warnings. Fixes RT #47119.
153 0.86 Tue, Jun 16, 2009
155 - If you redefined a subroutine at runtime and then wrapped it
156 with a method modifier, the modifier could in some cases wrap
157 the original version of the subroutine. Fixes RT #46957.
160 - make_immutable issues a warning instead of overriding an
161 existing DESTROY method (Dylan William Hardison). Fixes RT
164 0.85 Sat, Jun 6, 2009
165 * Class::MOP::Attribute
166 - Allow default values to be Class::MOP::Methods. (Florian
168 - Test the above. (Rhesa Rozendaal)
169 - Tweak original commit so the intent matches the accepted
170 behavior (Nicholas Perez)
173 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
176 - Add direct_subclasses method (Sartak)
177 - Tests for subclasses and direct_subclasses (Sartak)
178 - subname is no longer used unconditionally in add_method, but
179 only if the code reference's name is '__ANON__' (nothingmuch)
180 - Add a hook for _superclasses_updated (Sartak)
183 - Remove long, old warning about possibly outdated modules
186 0.84 Tue, May 12, 2009
188 - Depend on Text::Exception 0.27 to avoid failing tests ond old
192 - Made is_class_loaded a little stricter. It was reporting that
193 a class was loaded if it merely had an @ISA variable in its
194 stash. Now it checks that the @ISA var has elements in it.
195 - Deprecate in_global_destruction and subname re-exporting
199 - Explicitly use Devel::GlobalDestruction and Sub::Name
202 * Class::MOP::Package
203 - Disable prototype mismatch warnings for add_package_symbol.
206 - Add test for finding methods from $meta->name->meta before immutable,
209 0.83 Mon, April 27, 2009
211 - Fix segfault when calling get_method_map on a metaclass for an empty
214 0.82_02 Fri, April 24, 2009
215 * Class::MOP::Method::Inlined
216 - Don't inline if the expected method is not defined at all (happens with
217 e.g. Moose::Object::_new is the expected method due to an overridden
220 - Some tests were trying to load Class::MOP::Immutable, which
221 was removed in 0.82_01.
223 0.82_01 Thu, April 23, 2009
224 * Class::MOP::Immutable (and others)
225 - Refactor the immutability system to use a pre-defined class
226 for the immutable metaclass of Class::MOP::Class::Immutable::$class
227 - Rather than generating methods into this class every time, use
228 a Trait (basic mixin) to supply the cached methods
229 - Remove the hack that returns the mutable metaclass for
230 metacircularity in order to provide consistent meta-metaclasses
231 for the Moose compatibility handling code
232 (mst broke it, nothingmuch fixed it)
234 0.82 Mon, April 20, 2009
236 - The deprecation wrappers for some renamed methods were not
237 passing arguments to the new method. (nothingmuch)
239 * Class::MOP::Immutable
240 - Warn during immutablization if the local class provides its own
241 constructor, to parallel the warning in Moose when a superclass
242 provides its own constructor (doy)
244 0.81 Tue, April 7, 2009
247 * Class::MOP::Instance
248 * Class::MOP::Attribute
249 * Class::MOP::Method::Accessor
250 * Class::MOP::Method::Constructor
251 - Include stack traces in the deprecation warnings introduced in
252 0.80_01. (Florian Ragwitz)
255 - Avoid c compiler warnings by declaring some unused function
256 arguments. (Florian Ragwitz)
258 0.80_01 Sun, April 5, 2009
260 - Make sure to preserve any compiler flags already defined in
261 Config.pm. Patch by Vincent Pit. RT #44739.
263 * Many methods have been renamed with a leading underscore, and a
264 few have been deprecated entirely. The methods with a leading
265 underscore are considered "internals only". People writing
266 subclasses or extensions to Class::MOP should feel free to
267 override them, but they are not for "public" use.
270 - construct_class_instance => _construct_class_instance (use new_object)
271 - construct_instance => _construct_instance (use new_object)
272 - check_metaclass_compatibility => _check_metaclass_compatibility
273 - create_meta_instance => _create_meta_instance (use get_meta_instance)
274 - clone_instance => _clone_instance (use clone_object)
275 - compute_all_applicable_methods is deprecated, use get_all_methods
276 - compute_all_applicable_attributes is deprecated, use get_all_attributes
278 - Class::MOP::Instance
279 - bless_instance_structure is deprecated and will be removed
283 - create has been renamed to _instantiate_module. This method
284 does not construct an object, it evals some code that
285 creates the relevant package in Perl's symbol table.
287 - Class::MOP::Method::Accessor
288 - initialize_body => _initialize_body (this is always called
289 when an object is constructed)
290 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
292 - Class::MOP::Method::Constructor
293 - initialize_body => _initialize_body (this is always called
294 when an object is constructed)
295 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
296 - attributes => _attributes
297 - meta_instance => _meta_instance
299 0.80 Wed, April 1, 2009
301 - Call user_class->meta in fewer places, with the eventual goal
302 of allowing the user to rename or exclude ->meta
303 altogether. Instead uses Class::MOP::class_of. (Sartak)
306 - New class_of function that should be used to retrieve a
307 metaclass. This is unlike get_metaclass_by_name in that it
308 accepts instances, not just class names. (Sartak)
311 - load_first_existing_class didn't actually load the first
312 existing class; instead, it loaded the first existing and
313 compiling class. It now throws an error if a class exists (in
314 @INC) but fails to compile. (hdp)
318 - we had some semi-buggy code that purported to provide a
319 HAS_ISAREV based on whether mro had get_isarev (due to an
320 oversight, it always returned 1). Since mro and MRO::Compat
321 have always had get_isarev, HAS_ISAREV was pointless. This
322 insight simplified the subclasses method by deleting the
323 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
325 0.79 Fri, March 29, 2009
326 * No changes from 0.78_02.
328 0.78_02 Thu, March 26, 2009
330 * Class::MOP::Immutable
331 - A big backwards-incompatible refactoring of the Immutable API,
332 and the make_immutable/make_mutable pieces of the Class
333 API. The core __PACKAGE__->meta->make_immutable API remains
334 the same, however, so this should only affect the most
338 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
339 has been fixed to be backwards compatible with 5.8.x.
342 - Add a hook for rebless_instance_away (Sartak)
343 - Use blessed instead of ref to get an instance's class name
344 in rebless_instance. (Sartak)
346 0.78_01 Wed, March 18, 2009
348 - Revised and reorganized all of the API documentation. All
349 classes now have (more or less) complete API documentation.
352 * Class::MOP::Instance
353 - Reblessing into a package that supports overloading wasn't
354 properly adding overload magic to the object due to a bug
355 in (at least) 5.8.8. We now use $_[1] directly which seems
356 to set the magic properly. (Sartak)
358 * Class::MOP::Attribute
359 - The process_accessors method is now private. A public alias
360 exists (and will stick around for a few releases), but it
361 warns that calling the public method is deprecated.
363 * Class::MOP::Method::Generated
364 - Removed the new and _new methods, since this is an abstract
365 base class, and all existing subclasses implement their own
369 - Stop is_class_loaded from thinking a class is loaded if it
370 only has an empty GV (Florian Ragwitz).
371 - Add a test for this (Yappo).
372 - Refactor get_all_package_symbols to allow short-circuiting
374 - Use this in is_class_loaded (Florian Ragwitz).
375 - Stop segfaulting when trying to get the name from a sub that's
376 still being compiled (Florian Ragwitz).
377 - Add tests for this (Florian Ragwitz).
378 - Prefix all public symbols with "mop_" (Florian Ragwitz).
379 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
380 - Simplify creating simple xs reader methods (Florian Ragwitz).
381 - Make everything compile with c++ compilers (Florian Ragwitz).
382 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
385 - Remove optional test plans for tests depending on Sub::Name as
386 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
389 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
391 0.78 Mon, February 23, 2009
392 * No changes from 0.77_01
394 0.77_01 Sun, February 22, 2009
396 - This package now requires its XS components. Not using
397 Sub::Name lead to different behavior and bugginess in the pure
398 Perl version of the code. A Moose test would fail when run
399 against the pure Perl version of this code.
401 * Class::MOP::Instance
402 - The inline_* methods now quote attribute names themselves, and
403 don't expect to receive a quoted value.
406 0.77 Sat, February 14, 2009
408 - Avoid assertion errors on debugging perls in is_class_loaded
412 - Fixed various corner cases where is_class_loaded incorrectly
413 returned true for a class that wasn't really loaded. (Dave
417 - Add get_all_method_names (Sartak)
418 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
420 * Class::MOP::Package
421 - Disable deprecated get_all_package_symbols in list
422 context. (Florian Ragwitz)
425 - Make sure we generate a BSD-compatible Makefile (Florian
429 - The misspelled "check_metaclass_compatability" method we've
430 kept around for backwards compat_i_bility will be removed in a
431 near future release. You've been warned.
433 0.76 Thu, January 22, 2009
434 * Class::MOP::Method::Generated
435 - Added new private methods to support code generation, which
436 are being used by Moose and can be used by MooseX
438 - Generated methods are now generated with a #line directive
439 reflecting the source of the generated method. (nothingmuch)
442 - Clarified documentation of methods that return
443 Class::MOP::Method objects. (doy)
446 - Clarified documentation of the metaclass cache methods. (Sartak)
449 - Add test showing how the xs Class::MOP::is_class_loaded can
450 be made to operate differently to the pure perl version (t0m)
452 0.75 Wed, December 31, 2008
454 - A class that was made immutable and then mutable could end up
455 sharing an immutable transformer object
456 (Class::MOP::Immutable) with other classes, leading to all
457 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
459 0.74 Tue, December 25, 2008
461 - Add an xs implementation of Class::MOP::is_class_loaded (closes
462 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
463 - Changed internals to make prehashing of hash keys easier and less
464 error-prone. (Florian Ragwitz)
466 - Fix documentation to show that around modifiers happen on both
467 sides of the modified method. (Dave Rolsky)
469 0.73 Tue, December 16, 2008
471 - Don't use Perl_mro_meta_init. It's not part of the public perl
472 api. Fixes failures to build on Win32 (RT #41750). (Florian
474 * t/082_get_code_info.t
475 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
476 munger anonymous subs when under -d and so making the tests
477 succeed in that case.
479 0.72 Mon, December 8, 2008
480 * Class::MOP::Package
481 - Pass options to _new, so subclass' attributes can be
484 - In the docs, indicate that package_name and name are required
485 when calling ->wrap (Stefan O'Rear)
487 0.71_02 Fri, December 5, 2008
488 * Class::MOP::Immutable
489 - Added a new attribute, inlined_constructor, which is true if
490 the constructor was inlined.
491 * Class::MOP::Package
492 - Make get_all_package_symbols return a hash ref in scalar
493 context and deprecate calling it in list context with a
494 warning. (Florian Ragwitz)
496 - Various improvements and refactoring, making things more robust and
497 easier to maintain. (Florian Ragwitz)
499 0.71_01 Wed, December 3, 2008
501 - Add an "execute" method to invoke the body so
502 we can avoid using the coderef overload (Sartak)
503 * Class::MOP::Immutable
504 - When we memoize methods, get their results lazily
505 to remove some compile-time cost (Sartak)
506 - Small speedup from eliminating several method
509 - Some small internal tweaks to try to reduce the number of
510 times we call get_method_map when bootstrapping the MOP. This
511 might make loading Class::MOP (and Moose) a little
512 faster. (Dave Rolsky)
513 - Implemented an optional XS version of get_method_map. Mostly
514 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
515 help form Florian Ragwitz. (Dave Rolsky)
516 - Make the behaviour of of get_all_package_symbols (and
517 therefore get_method_map) consistent for stub methods. Report
518 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
520 0.71 Wed November 26, 2008
523 - Actual package creation has moved upward from
524 Class to Module so that Moose roles can share
527 0.70_01 Mon, November 19, 2008
529 - Fixes for failures with blead (Florian Ragwitz)
530 - Silenced compiler warnings (Florian Ragwitz)
532 0.70 Fri, November 14, 2008
534 - Fixed an odd corner case where the XS version of
535 get_all_package_symbols could cause a segfault. This only
536 happened with inlined constants in Perl 5.10.0 (Florian
539 0.69 Fri, November 7, 2008
540 * Class::MOP::Method::Wrapped
541 - Added introspection methods for method modifiers (Dave Rolsky)
544 0.68 Fri October 24, 2008
546 - Make load_class require by file name instead of module name.
547 This stops confusing error messages when loading '__PACKAGE__'.
549 - Add load_one_class_of function to enable you to load one of a
550 list of classes, rather than having to call load_class multiple
551 times in an eval. (t0m)
553 0.67 Tue October 14, 2008
555 - Call a method on the class after setting the superclass list
556 so that we can get Perl to detect cycles before MRO::Compat
557 spirals into an infinite loop (sartak)
558 - Reported by Schwern, [rt.cpan.org #39001]
559 - In create(), pass unused options on to initialize()
560 - added test for this
562 0.66 Sat September 20, 2008
563 !! This release has an incompatible change regarding !!
564 introspection of a class's method with Class::MOP::Class !!
567 - We (us maintainers) now run all tests with XS and then without
568 XS, which should help us catch skew between the XS/pure Perl
572 ! The alias_method method has been deprecated. It now simply
573 calls add_method instead. There is no distinction between
574 aliased methods and "real" methods.
576 This means that methods added via alias_method now show up as
577 part of the class's method list/map. This is a backwards
578 incompatible change, but seems unlikely to break any
579 code. Famous last words. (Dave Rolsky)
582 - Fixed the spelling of "compatibility", but we still have a
583 "check_metaclass_compatability" method for backwards
586 0.65 Mon September 1, 2008
587 For those not following the series of dev releases, the changes
588 from 0.64 from 0.65 can mostly be summed up as a lot performance
589 improvements by nothingmuch, including new optional XS versions of
590 some methods. Also, Class::MOP now works _without_ any XS modules,
591 for sad systems without a compiler.
594 - Added name and package_name XS accessors, and make sure all
595 the XS and Perl versions work the same way. (Dave Rolsky)
598 - The XS versions of various methods just returned undef when
599 called class methods, rather than dying like the pure Perl
600 versions. (Dave Rolsky)
602 0.64_07 Fri August 29, 2008
604 - Silenced warnings that managed to break Moose tests when XS
605 was loaded. (Dave Rolsky)
606 - Some XS versions of methods were ignored because of typos in
607 MOP.xs. (Dave Rolsky)
609 0.64_06 Mon August 25, 2008
610 * Class::MOP (MOP.xs)
611 - Another MS VC++ fix, cannot declare a variable in the middle
612 of a scope (Taro Nishino).
614 0.64_05 Sun August 24, 2008
616 - None of the dev releases actually loaded the XS properly, but
617 we silently fell back to the pure Perl version of the
620 * Class::MOP (MOP.xs)
621 - Replaced some code that used functions not available on Visual
622 C++ with some Perl XS API bits (Dave Rolsky).
624 0.64_04 Sat August 23, 2008
626 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
628 * pod.t and pod_coveraget.t
629 - These are no longer shipped with the tarball because of bogus
630 failures from CPAN testers. (Dave Rolsky)
632 0.64_03 Thu August 21, 2008
633 * Class::MOP::Package
634 - Some (legit) code was misparsed by earlier 5.8.x
635 releases. (nothingmuch)
638 - Fix a constant in void context warning (nothingmuch)
640 0.64_02 Thu August 21, 2008
641 * Makefile.PL and Class::MOP
642 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
645 - Add missing prereqs that got lost in the switch away from
648 * Class::MOP::Instance
649 - New method - get_all_attributes (nothingmuch)
651 0.64_01 Wed August 20, 2008
653 - We now check to see if you have a compiler. If you don't, the
654 module installs without some XS bits, but will work the same
655 as with XS. This should make it easier to install on platforms
656 without a compiler (like Windows). (Dave Rolsky)
659 - Perl 6 style attribute naming replaced with sane style ('methods', not
660 '%!methods'). These changes should not impact any existing API uses.
664 - Quite a number of optimizations based on profiling, including
665 allowing constructors to take hash references instead of
666 hashes, duplicating some frequently used code in XS, and
667 making constructors immutable. These changes should not impact
668 any existing API uses. (nothingmuch)
671 - Constructors now respect the meta attributes of their subclasses,
672 facilitating MOP extensibility. More related changes will happen in the
673 next several releases. (nothingmuch)
676 - New method - get_all_methods, replaces the deprecated
677 compute_all_applicable_methods. get_all_attributes provided for
678 consistency (nothingmuch)
679 - New method - wrap_method was refactored out of get_method_map
681 - New API for meta instance invalidation - invalidate_meta_instance,
682 invalidate_meta_instances, add_dependent_meta_instance,
683 remove_dependent_meta_instance, called automatically when attribute
684 definitions change and allows notification of dependent subclasses.
687 0.64 Sun August 3, 2008
688 * Class::MOP::Immutable
689 - fixing subtle edge case in immutable when you
691 - clean up option processing (nothingmuch)
693 * Class::MOP::Instance
694 - inlined initialize slot didn't match
695 non-inlined (nothingmuch)
697 0.63 Mon July 7, 2008
699 - load_class will initialize a metaclass even if
700 the class is already loaded (sartak)
701 - load_class now returns the metaclass instance
702 instead of just 1 (sartak)
705 - better error messages (sartak and Dave Rolsky)
707 0.62 Wed June 18, 2008
708 - in is_class_loaded, recognize scalar references (as opposed to globs) in
709 the symbol table as methods (these are optimized constant subs)
711 0.61 Fri. June 13, 2008
712 - Okay, lets give this another try and see if PAUSE
713 recognizes it correct this time.
715 0.60 Thurs. Jun 12, 2008
716 - Fixed a version number issue by bumping all modules
719 0.59 Thurs. Jun 12, 2008
720 !! Several fixes resulting in yet another 25-30% speedup !!
723 - now stores the instance of the instance
724 metaclass to avoid needless recomputation
725 and deletes it when the cache is blown
726 - introduce methods to query Class::MOP::Class for
727 the options used to make it immutable as well as
728 the proper immutable transformer. (groditi)
730 * Class::MOP::Package
731 - {add, has, get, remove}_package_symbol all
732 now accept a HASH ref argument as well as the
733 string. All internal usages now use the HASH
737 - MOP.xs does sanity checks on the coderef
739 - is_class_loaded check now uses code that
740 was improved in Moose's ClassName type
742 - nonsensical (undef, empty, reference) class
743 names now throw a more direct error in
745 - tests for this and other aspects of
751 Class::MOP::Method::Wrapped
752 Class::MOP::Attribute
753 - switched usage of reftype to ref because
756 0.58 Thurs. May 29, 2008
757 (late night release engineering)--
759 - fixing the version is META.yml, no functional
760 changes in this release
762 0.57 Wed. May 28, 2008
763 !! Several speedups resulting in 20-25% speedups !!
764 || (thanks to konobi, groditi, mst & CataMoose) !!
767 - made get_method_map use list_all_package_symbols
768 instead of manually grabbing each symbol
769 - streamlining &initialize somewhat, since it gets
772 * Class::MOP::Package
773 - made {get, has}_package_symbol not call
775 - inlining a few calls to &name with
776 direct HASH access key access
777 - added get_all_package_symbols to fetch
778 a HASH of items based on a type filter
779 similar to list_all_package_symbols
780 - added tests for this
783 Class::MOP::Method::Constructor
784 Class::MOP::Method::Generated
785 Class::MOP::Method::Accessor
786 - added more descriptive error message to help
787 keep people from wasting time tracking an error
788 that is easily fixed by upgrading.
790 * Class::MOP::Immutable
791 - Don't inline a destructor unless the user actually
793 - added tests for this
795 0.56 Saturday, May 24, 2008
797 - we now get the &check_package_cache_flag
798 function from MRO::Compat
799 - All XS based functionality now has a
800 Pure Perl alternative
801 - the CLASS_MOP_NO_XS environment variable
802 can now be used to force non-XS versions

813 - added the ability to "wrap" methods when
814 making the class immutable
817 - now handling the edge case of ->meta->identifier
818 dying by wrapping add_package_symbol to specifically
819 allow for it to work.
820 - added tests for this
822 * Class::MOP::Attribute
824 Class::MOP::Immutable
825 - any time a method meta object is constructed
826 we make sure to pass the correct package and
827 method name information
830 Class::MOP::Method::Wrapped
831 Class::MOP::Method::Generated
832 Class::MOP::Method::Accessor
833 Class::MOP::Method::Consructor
834 - the &wrap constructor method now requires that a
835 'package_name' and 'name' attribute are passed. This
836 is to help support the no-XS version, and will
837 throw an error if these are not supplied.
838 - all these classes are now bootstrapped properly
839 and now store the package_name and name attributes
842 ~ Build.PL has been removed since the
843 Module::Install support has been removed
845 0.55 Mon. April 28, 2008
846 - All classes now have proper C3 MRO support
847 - added MRO::Compat as a dependency to allow
848 for the C3 MRO support to Just Work in all
852 - rebless_instance now returns the instance
853 it has just blessed, this is mostly to
855 - set the attr correctly in rebless_instance
856 when it has no init_arg
857 - tweaked &linear_isa and &class_precedence_list
858 to support c3 classes.
860 0.54 Fri. March, 14, 2008
863 - making sure that load_class never gets
864 passed a value from @_ or $_ to squash
865 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
868 - make_{immutable,mutable} now return 1
870 - improved error handling in ->create method
871 - rebless_instance now takes extra params which
872 will be used to populate values
873 - added tests for this
876 - localizing the Data::Dumper configurations so
877 that it does not pollute others (RT #33509)
883 Class::MOP::Attribute
884 - these classes no longer define their own ->meta,
885 but instead just inherit from Class::MOP::Object
887 * Class::MOP::Instance
888 Class::MOP::Immutable
889 - these classes now inherit from Class::MOP::Object
892 - fixed the filename length on several
893 test files so we install on VMS better
895 - fixed incorrect use of catdir when it
896 should be catfile (RT #32385)
898 0.53 Thurs. Feb. 14, 1008
899 ~~ several doc. fixes and updates ~~
902 Class::MOP::Method::Constructor

905 to indicate that no constructor args can
906 be passed (thanks to nothingmuch)
907 - added tests for this
908 - added attribute initializer attribute (rjbs)
911 - making this use the new init_arg => undef
912 feature instead of the silly hack from
913 before (thanks to nothingmuch)
915 0.52 Tues. Jan. 22, 2008
917 - fixed bug in rebless_instance
920 * Class::MOP::Method::Constructor
921 - removed assumptions about the existence of
924 0.51 Mon. Jan. 14, 2008
925 ~~~ some misc. doc. fixes ~~~
926 ~~ updated copyright dates ~~
929 - now sets the IS_RUNNING_ON_5_10
930 constant so that we can take advantage
931 of some of the nice bits of 5.10
934 - uses the IS_RUNNING_ON_5_10 flag to
935 optimize the &linearized_isa method
936 and avoid the hack/check for circular
937 inheritence in &class_precedence_list
938 - added rebless_instance method (Sartak)
939 - added tests for this
941 * Class::MOP::Immutable
942 - the immutable class now keeps track of
943 the transformer which immutablized it
945 * Class::MOP::Instance
946 - added rebless_instance_structure method (Sartak)
947 - added tests for this
949 0.50 Fri. Dec. 21, 2007

963 !! Class::MOP now loads 2 x faster !!
964 !! with XS speedups (thanks konobi) !!
967 - removed the dependency on B
968 - added two XS functions (thanks konobi)
969 - get_code_info($code) which replaces all
970 the B fiddling we were doing with
971 faster/leaner XS level fiddling
972 - check_package_cache_flag($pkg_name) which
973 returns the PL_sub_generation variable to
974 be used to help manage method caching.
977 In 5.10 or greater this will actually
978 use the mro::get_pkg_gen instead to give
979 even more accurate caching information.
980 blblack++ for that stuff :)
983 - added the &subclasses method (thanks rlb)
984 - added the update_package_cache_flag and
985 reset_package_cache_flag which help keep
986 track of when we need to re-fetch the
988 - Several small improvements to take advantage
989 of the new method map caching features
991 0.48 Mon. Nov. 26, 2007
992 * Class::MOP::Attribute
993 - fixed get_read/write_method to handle the
994 HASH ref case, which makes the

996 - added more tests for this
998 0.47 Sat. Nov. 24, 2007
999 * Class::MOP::Attribute

1001 - added more tests for this
1003 0.46 Fri. Nov. 23, 2007
1005 - added the linearized_isa method instead of constantly
1006 pruning duplicate classes (this will be even more
1007 useful in the 5.10-compat version coming soon)
1009 * Class::MOP::Attribute
1010 - added the get_read_method_ref and get_write_method_ref
1011 methods which allow you to retrieve a CODE ref which
1012 can always be used to read or write an attribute.
1014 0.45 Thurs. Nov. 13, 2007
1015 * Class::MOP::Attribute
1016 - Fix error message on confess (groditi)
1018 0.44 Thurs. Nov. 13, 2007

1029 call through (groditi)
1031 * Class::MOP::Attribute

1042 - removed the relevant attributes
1044 * Class::MOP::Method::Constructor
1045 - fixed the cached values we had to be more sane
1046 - made this a subclass of Class::MOP::Method::Generated
1047 - fixed generated constructor so it properly handles
1049 - added tests for this
1050 - added the option to allow for both inlined and
1051 non-inlined constructors.
1052 - Update inlined methods for builder and predicate changes (groditi)
1054 * Class::MOP::Method::Generated
1055 - added this class as an abstract base for the
1056 Class::MOP::Method::{Constructor,Accessor} classes
1057 - added tests for this

1070 - alter symbol table handling to deal with 5.8.x and 5.9.x
1073 - Get rid of the crappy workaround from 0.40/41
1075 0.41 Sun. July 15, 2007
1077 Arghh!!! My TODO test didn't work, so I handle
1078 it manually now so that people can use this
1079 with 5.9.5/bleadperl without issue.
1081 0.40 Tues, July 3, 2007
1083 ~ marked a test in 003_methods.t as TODO
1084 for perl 5.9.5 (this test is irrelvant to
1085 the module functioning on 5.9.5 for the most
1088 0.39 Mon. June 18, 2007
1089 * Class::MOP::Immutable
1090 - added make_metaclass_mutable + docs (groditi)
1091 - removed unused variable
1092 - added create_immutable_transformer
1093 necessary for sane overloading of immutable behavior
1094 - tests for this (groditi)
1097 - Immutability can now be undone,
1098 added make_mutable + tests + docs (groditi)
1099 - Massive changes to the way Immutable is done
1100 for details see comments next to make_immutable
1101 This fixes a bug where custom metaclasses broke
1102 when made immutable. We are now keeping one immutable
1103 metaclass instance per metaclass instead of just one
1104 to prevent isa hierarchy corruption. Memory use will go
1105 up, but I suspect it will be neglible.
1106 - New tests added for this behavior. (groditi)
1108 0.38 Thurs. May 31, 2007
1109 ~~ More documentation updates ~~
1111 * Class::MOP::Package
1112 - we now deal with stub methods properly
1113 - added tests for this
1114 - fixed some tests failing on 5.9.5 (thanks blblack)
1116 * Class::MOP::Attribute
1117 - added get_read_method and get_write_method
1118 thanks to groditi for this code, tests
1120 - added tests and POD for this
1123 - fixed RT issue #27329, clone object now
1124 handles undef values correctly.
1125 - added tests for this
1126 - Corrected anon-class handling so that they
1127 will not get reaped when instances still
1128 exist which need to reference them. This is
1129 the correct behavior, hopefully this is an
1130 obscure enough feature that there are not too
1131 many work arounds out in the wild.
1132 - added tests for this by groditi
1133 - updated docs to explain this
1136 - load custom metaclasses automatically (thanks groditi)
1137 - added tests for this behavior
1139 0.37 Sat. March 10, 2007
1140 ~~ Many, many documentation updates ~~
1143 - added &load_class and &is_class_loaded
1144 - added tests and docs for these
1146 * Class::MOP::Attribute

1148 avoid setting off bool-overloads (found by Carl Franks)
1152 - bad name in a test, causing meaningless failuress.
1157 ~~ GLOBAL CHANGES ~~
1158 - All attribute names are now consistent and follow Perl 6
1159 style (prefixed with the sigil, and ! as the twigil for
1160 private attrs). This should not affect any code, unless
1161 you broke encapsulation, in which case, it is your problem
1164 !! Class::MOP::Class::Immutable has been removed
1166 * Class::MOP::Method::Constructor
1167 - this has been moved out of Class::MOP::Class::Immutable
1168 and is a proper subclass of Class::MOP::Method now.
1171 - this module now uses Class::MOP::Immutable for the
1172 immutable transformation instead of
1173 Class::MOP::Class::Immutable.
1175 + Class::MOP::Immutable
1176 - this module now controls the transformation from a mutable
1177 to an immutable version of the class. Docs for this will
1178 be coming eventually.
1181 0.36 Sun. Nov. 5, 2006
1183 - added a few 'no warnings' lines to keep annoying
1184 (and meaningless) warnings from chirping during
1188 - some more bootstrapping is now done on the new
1191 * Class::MOP::Class::Immutable
1193 - constructor generation is now handled by
1194 the Class::MOP::Method::Constructor class
1196 * Class::MOP::Method::Constructor
1197 - created this to handle constructor generation
1198 in Class::MOP::Class::Immutable
1200 * Class::MOP::Attribute
1202 - attributes now delegate to the
1203 Class::MOP::Method::Accessor to generate
1206 * Class::MOP::Method::Accessor
1207 - all accessor generation functions from
1208 Class::MOP::Attribute have been moved here
1210 0.35 Sat. Sept. 30, 2006

1213 - initial prototype of a class browser, more
1214 on this to come. Comments and patches are
1218 - All Class::MOP::* accessors are no longer
1219 re-generated in the bootstrap, instead
1220 they are aliased from the originals
1221 - fixed tests to reflect
1222 - added Class::MOP::Method (and its subclasses)
1224 - adjusted tests for this
1225 - added the Class::MOP::Instance attributes
1228 * Class::MOP::Method

1231 but are actual objects which can be CODE-ified
1232 - adjusted tests to compensate
1233 - adjusted docs for this
1236 - changed how methods are dealt with to
1237 encapsulate most of the work into the
1238 &get_method_map method
1239 - made several adjustments for the change
1240 in Class::MOP::Method
1241 - &add_attribute now checks if you are adding
1242 a duplicate name, and properly removes the
1243 old one before installing the new one
1244 - added tests for this
1245 - adjusted docs for this
1247 * Class::MOP::Class::Immutable
1248 - added caching of &get_method_map
1249 - fixed issue with &get_package_symbol
1250 - cleaned up the methods that die (patch by David Wheeler)

1253 - added filtering capabilities to
1254 &list_all_package_symbols
1256 0.34 Sat. Aug. 26, 2006
1258 - added the %:methods attribute, which like
1259 the $:version and such just actually goes
1260 to the symbol table to get it's stuff.
1261 However, it makes the MOP more complete.
1263 - The &create method now requires that all
1264 but the package name now is passed in as
1265 named parameters. See docs for more info.
1266 - updated docs and tests for this
1268 * Class::MOP::Object
1269 - added &dump method to easily Data::Dumper

1290 - reference values (other than CODE refs)
1291 are no longer allowed for defaults
1292 - added tests for this
1294 * Class::MOP::Package
1295 - fixed an issue with perl 5.8.1 and how it deals
1296 with symbol tables. The namespace hash is now
1297 always reloaded from the symbol table.
1299 ~ lots of misc. documentation cleanup
1301 0.32 Sat. Aug. 12, 2006
1302 + added Class::MOP::Object so that the
1303 metamodel is more complete (and closer
1304 to what Perl 6 will probably be).

1308 the primary gateway between the metaclass
1309 and the Perl 5 symbol table
1310 - added many tests for this

1317 use Class::MOP::Package methods instead
1319 * Class::MOP::Module
1320 - adding the $:version attribute in the bootstrap
1321 so that Module has a version as an attribute
1322 - see comment in Class::MOP for details
1323 - added the $:authority attribute to this module
1324 as well as an &identifier method, to bring us
1325 ever closer to Perl 6 goodness
1326 - I have added $AUTHORITY to all the modules
1327 - added tests for this

1343 anywhere within the class hierarchy
1345 * Class::MOP::Attribute
1346 - added &set_value and &get_value for getting
1347 the value of the attribute for a particular
1350 0.30 Wed. July 5, 2006
1351 ---------------------------------------
1352 This is the first version of Class::MOP
1353 to introduce the immutable features which
1354 will be used for optimizating the MOP.
1355 This support should still be considered
1356 experimental, but moving towards stability.
1357 ---------------------------------------
1359 * Created Class::MOP::Class::Immutable
1361 * Created the Class::MOP::Package and
1362 Class::MOP::Module classes to more
1363 closely conform to Perl 6's meta-model
1366 - now inherits from Class::MOP::Module
1367 - several methods moved to ::Module and
1368 ::Package and now inherited
1369 - added tests for this
1371 * Class::MOP::Instance
1372 - added an is_inlinable method to allow other
1373 classes to check before they attempt to optimize.
1374 - added an inline_create_instance to inline
1375 instance creation (of course)
1378 - the Class::MOP::Class::*_package_variable
1379 methods are all now methods of Class::MOP::Package
1380 and called *_package_symbol instead. This is
1381 because they are now more general purpose symbol
1382 table manipulation methods.
1384 0.29_02 Thurs. June 22, 2006
1385 ++ DEVELOPER RELEASE ++
1387 - small change in &create so that it behaves
1388 properly when inherited
1389 - small fix to &clone_instance
1391 0.29_01 Fri. May 12, 2006
1392 ++ DEVELOPER RELEASE ++
1393 - This release works in combination with
1394 Moose 0.09_01, it is a developer release
1395 because it introduces a new instance
1396 sub-protocol and has not yet been
1400 - anon-classes are now properly garbage collected
1401 - added tests for this
1402 - improved method modifier wrapping

1419 - added ArrayBasedStorage example to show
1420 instance storage using ARRAY refs instead of
1422 - added tests for this

1439 - added tests for this
1440 - added get_all_metaclasses, get_all_metaclass_names
1441 and get_all_metaclass_instances method to allow
1442 access to all the cached metaclass objects.
1443 - attribute slot initialization is now the responsibility
1444 of the attribute itself, and construct_instance now
1445 delegates appropriately
1447 * Class::MOP::Attribute
1448 - attribute slot initialization is now the responsibility
1449 of the attribute itself, so we added a method for it
1450 called initialize_instance_slot

1476 because otherwise, it does ugly things in Moose.
1477 - added test case for this
1479 0.21 Wed. March 15, 2006
1481 - fixed issue where metaclasses are reaped from
1482 our cache in global destruction, and so are not
1483 available in DESTORY calls
1485 0.20 Thurs. March 2, 2006
1486 - removed the dependency for Clone since
1487 we no longer to deep-cloning by default.
1489 * Class::MOP::Method

1513 0.12 Thurs. Feb 23, 2006
1514 - reduced the dependency on B, no need to always
1518 - added docs to the C3 method dispatch order test

1529 - added docs and tests
1531 0.10 Tues Feb. 14, 2006
1532 ** This release was mostly about writing more tests and
1533 cleaning out old and dusty code, the MOP should now
1534 be considered "ready to use".
1536 - adding more tests to get coverage up a little higher,
1537 mostly testing errors and edge cases.
1538 - test coverage is now at 99%
1541 - no longer optionally exports to UNIVERSAL::meta or
1542 creates a custom metaclass generator, use the
1543 metaclass pragma instead.
1546 - fixed a number of minor issues which came up in the
1547 error/edge-case tests
1549 * Class::MOP::Attribute
1550 - fixed a number of minor issues which came up in the

1556 0.06 Thurs Feb. 9, 2006
1558 - adding new metaclass pragma to make setting up the
1559 metaclass a little more straightforward
1562 - clean up bootstrapping to include more complete
1563 attribute definitions for Class::MOP::Class and
1564 Class::MOP::Attribute (accessors, readers, writers,
1565 etc.) ... it is redundant, but is useful meta-info
1569 - fixing minor meta-circularity issue with &meta, it
1570 is now more useful for subclasses
1571 - added &get_attribute_map as an accessor for the
1572 hash of attribute meta objects
1573 - &compute_all_applicable_attributes now just returns
1574 the attribute meta-object, rather than the HASH ref
1575 since all the same info can be gotten from the
1576 attribute meta-object itself
1577 - updated docs & tests to reflect
1578 - added &clone_instance method which does a deep clone
1579 of the instance structure created by &construct_instance
1580 - added docs & tests for this
1581 - added Clone as a dependency
1582 - added &new_object and &clone_object convience methods to
1583 return blessed new or cloned instances
1584 - they handle Class::MOP::Class singletons correctly too
1585 - added docs & tests for this
1586 - cleaned up the &constuct_class_instance so that it behaves
1587 more like &construct_instance (and managed the singletons too)
1588 - added the &check_metaclass_compatibility method to make sure
1589 that metaclasses are upward and downward compatible.
1590 - added tests and docs for this
1593 - adjusting code to use the &Class::MOP::Class::meta
1595 - adjusting code to use the metaclass pragma
1597 0.05 Sat Feb. 4, 2006
1599 - added the &attribute_metaclass and &method_metaclass
1600 attributes which contain a metaclass name to use for
1601 attributes/methods respectively
1604 - bootstrap additional attributes for Class::MOP::Class
1607 - adjusted the example code and tests to use the new
1608 &attribute_metaclass feature of Class::MOP::Class
1609 - added new example:
1612 0.04 Fri Feb. 3, 2006
1614 - some documentation suggestions from #perl6
1616 * Class::MOP::Attribute
