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 0.92_01 Thu, Sep 10, 2009
16 - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
19 - Make sure XS code handles magical scalars correctly. (Goro Fuji)
22 - Documented the immutable_options method, which is useful if you need
23 to make a class mutable temporarily, and then nede to restore
24 immutability. (Dave Rolsky)
27 - Deprecated features have been moved to their own module,
28 Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)
33 - Move get_method_map and its various scaffolding into Package. (hdp)
36 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
37 the first argument, rather than just a coderef. (doy)
39 * Class::MOP::Attribute
41 - Allow attribute names to be false (while still requiring them to be
45 * Class::MOP::Method::Wrapped
46 - Fixing variable usage issues with the patch from previous
47 version, not properly using lexicals in the for
51 Japan Perl Association has sponsored Goro Fuji to improve startup
52 performance of Class::MOP and Moose. These enhancements may break
53 backwards compatibility if you're doing (or using) complex
54 metaprogramming, so, as always, test your code!
55 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
59 - Anonymous classes were not completely destroyed when they went
60 out of scope, leading to a memory leak. RT #47480. (Goro
64 - The get_method, has_method, and add_method methods no longer
65 use get_method_map. Method objects are instantiated
66 lazily. This significantly improves Class::MOP's load
70 - Inline fewer metaclass-level constructors since the ones we
71 have are perfectly fine. This reduces the number of string
74 * Class::MOP::Method::Wrapped
75 - If a method modifier set $_, this caused the modifier to blow
76 up, because of some weird internals. (Jeremy Stashewsky)
80 * Class::MOP::Class::Immutable::Trait
81 - Made the Trait act like a role with a bunch of "around"
82 modifiers, rather than sticking it in the inheritance
83 hierarchy. This fixes various problems that caused with
84 metaclass compatibility, which broke Fey::ORM.
87 - Allow a blessed code reference as the method body. Fixes a
88 problem interaction with MooseX::Types. (ash)
90 * Class::MOP::Instance
91 - add inline version of rebless_instance_structure. (doy)
92 - change inline_slot_access to use single quotes (gphat)
94 0.88 Tue, Jun 23, 2009
96 - Moved the __INSTANCE__ parameter to _construct_instance from
98 - Fixed some issues involving metaclasses of metaclasses and
101 0.87 Sun, Jun 21, 2009
103 - Made sure to always local-ize $@ and $SIG{__DIE__} before
104 calling an eval. Fixes RT #45973.
107 - Synced docs about immutability with the current reality (which
108 changed back in 0.82_01)
109 - Removed the immutable_transformer method, which had been
110 returning undef since 0.82_01 anyway.
113 - Got rid of tests which needed Moose and improved testing of
114 constructor/destructor inlining warnings. Fixes RT #47119.
116 0.86 Tue, Jun 16, 2009
118 - If you redefined a subroutine at runtime and then wrapped it
119 with a method modifier, the modifier could in some cases wrap
120 the original version of the subroutine. Fixes RT #46957.
123 - make_immutable issues a warning instead of overriding an
124 existing DESTROY method (Dylan William Hardison). Fixes RT
127 0.85 Sat, Jun 6, 2009
128 * Class::MOP::Attribute
129 - Allow default values to be Class::MOP::Methods. (Florian
131 - Test the above. (Rhesa Rozendaal)
132 - Tweak original commit so the intent matches the accepted
133 behavior (Nicholas Perez)
136 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
139 - Add direct_subclasses method (Sartak)
140 - Tests for subclasses and direct_subclasses (Sartak)
141 - subname is no longer used unconditionally in add_method, but
142 only if the code reference's name is '__ANON__' (nothingmuch)
143 - Add a hook for _superclasses_updated (Sartak)
146 - Remove long, old warning about possibly outdated modules
149 0.84 Tue, May 12, 2009
151 - Depend on Text::Exception 0.27 to avoid failing tests ond old
155 - Made is_class_loaded a little stricter. It was reporting that
156 a class was loaded if it merely had an @ISA variable in its
157 stash. Now it checks that the @ISA var has elements in it.
158 - Deprecate in_global_destruction and subname re-exporting
162 - Explicitly use Devel::GlobalDestruction and Sub::Name
165 * Class::MOP::Package
166 - Disable prototype mismatch warnings for add_package_symbol.
169 - Add test for finding methods from $meta->name->meta before immutable,
172 0.83 Mon, April 27, 2009
174 - Fix segfault when calling get_method_map on a metaclass for an empty
177 0.82_02 Fri, April 24, 2009
178 * Class::MOP::Method::Inlined
179 - Don't inline if the expected method is not defined at all (happens with
180 e.g. Moose::Object::_new is the expected method due to an overridden
183 - Some tests were trying to load Class::MOP::Immutable, which
184 was removed in 0.82_01.
186 0.82_01 Thu, April 23, 2009
187 * Class::MOP::Immutable (and others)
188 - Refactor the immutability system to use a pre-defined class
189 for the immutable metaclass of Class::MOP::Class::Immutable::$class
190 - Rather than generating methods into this class every time, use
191 a Trait (basic mixin) to supply the cached methods
192 - Remove the hack that returns the mutable metaclass for
193 metacircularity in order to provide consistent meta-metaclasses
194 for the Moose compatibility handling code
195 (mst broke it, nothingmuch fixed it)
197 0.82 Mon, April 20, 2009
199 - The deprecation wrappers for some renamed methods were not
200 passing arguments to the new method. (nothingmuch)
202 * Class::MOP::Immutable
203 - Warn during immutablization if the local class provides its own
204 constructor, to parallel the warning in Moose when a superclass
205 provides its own constructor (doy)
207 0.81 Tue, April 7, 2009
210 * Class::MOP::Instance
211 * Class::MOP::Attribute
212 * Class::MOP::Method::Accessor
213 * Class::MOP::Method::Constructor
214 - Include stack traces in the deprecation warnings introduced in
215 0.80_01. (Florian Ragwitz)
218 - Avoid c compiler warnings by declaring some unused function
219 arguments. (Florian Ragwitz)
221 0.80_01 Sun, April 5, 2009
223 - Make sure to preserve any compiler flags already defined in
224 Config.pm. Patch by Vincent Pit. RT #44739.
226 * Many methods have been renamed with a leading underscore, and a
227 few have been deprecated entirely. The methods with a leading
228 underscore are consider "internals only". People writing
229 subclasses or extensions to Class::MOP should feel free to
230 override them, but they are not for "public" use.
233 - construct_class_instance => _construct_class_instance (use new_object)
234 - construct_instance => _construct_instance (use new_object)
235 - check_metaclass_compatibility => _check_metaclass_compatibility
236 - create_meta_instance => _create_meta_instance (use get_meta_instance)
237 - clone_instance => _clone_instance (use clone_object)
238 - compute_all_applicable_methods is deprecated, use get_all_methods
239 - compute_all_applicable_attributes is deprecated, use get_all_attributes
241 - Class::MOP::Instance
242 - bless_instance_structure is deprecated and will be removed
246 - create has been renamed to _instantiate_module. This method
247 does not construct an object, it evals some code that
248 creates the relevant package in Perl's symbol table.
250 - Class::MOP::Method::Accessor
251 - initialize_body => _initialize_body (this is always called
252 when an object is constructed)
253 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
255 - Class::MOP::Method::Constructor
256 - initialize_body => _initialize_body (this is always called
257 when an object is constructed)
258 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
259 - attributes => _attributes
260 - meta_instance => _meta_instance
262 0.80 Wed, April 1, 2009
264 - Call user_class->meta in fewer places, with the eventual goal
265 of allowing the user to rename or exclude ->meta
266 altogether. Instead uses Class::MOP::class_of. (Sartak)
269 - New class_of function that should be used to retrieve a
270 metaclass. This is unlike get_metaclass_by_name in that it
271 accepts instances, not just class names. (Sartak)
274 - load_first_existing_class didn't actually load the first
275 existing class; instead, it loaded the first existing and
276 compiling class. It now throws an error if a class exists (in
277 @INC) but fails to compile. (hdp)
281 - we had some semi-buggy code that purported to provide a
282 HAS_ISAREV based on whether mro had get_isarev (due to an
283 oversight, it always returned 1). Since mro and MRO::Compat
284 have always had get_isarev, HAS_ISAREV was pointless. This
285 insight simplified the subclasses method by deleting the
286 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
288 0.79 Fri, March 29, 2009
289 * No changes from 0.78_02.
291 0.78_02 Thu, March 26, 2009
293 * Class::MOP::Immutable
294 - A big backwards-incompatible refactoring of the Immutable API,
295 and the make_immutable/make_mutable pieces of the Class
296 API. The core __PACKAGE__->meta->make_immutable API remains
297 the same, however, so this should only affect the most
301 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
302 has been fixed to be backwards compatible with 5.8.x.
305 - Add a hook for rebless_instance_away (Sartak)
306 - Use blessed instead of ref to get an instance's class name
307 in rebless_instance. (Sartak)
309 0.78_01 Wed, March 18, 2009
311 - Revised and reorganized all of the API documentation. All
312 classes now have (more or less) complete API documentation.
315 * Class::MOP::Instance
316 - Reblessing into a package that supports overloading wasn't
317 properly adding overload magic to the object due to a bug
318 in (at least) 5.8.8. We now use $_[1] directly which seems
319 to set the magic properly. (Sartak)
321 * Class::MOP::Attribute
322 - The process_accessors method is now private. A public alias
323 exists (and will stick around for a few releases), but it
324 warns that calling the public method is deprecated.
326 * Class::MOP::Method::Generated
327 - Removed the new and _new methods, since this is an abstract
328 base class, and all existing subclasses implement their own
332 - Stop is_class_loaded from thinking a class is loaded if it
333 only has an empty GV (Florian Ragwitz).
334 - Add a test for this (Yappo).
335 - Refactor get_all_package_symbols to allow short-circuiting
337 - Use this in is_class_loaded (Florian Ragwitz).
338 - Stop segfaulting when trying to get the name from a sub that's
339 still being compiled (Florian Ragwitz).
340 - Add tests for this (Florian Ragwitz).
341 - Prefix all public symbols with "mop_" (Florian Ragwitz).
342 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
343 - Simplify creating simple xs reader methods (Florian Ragwitz).
344 - Make everything compile with c++ compilers (Florian Ragwitz).
345 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
348 - Remove optional test plans for tests depending on Sub::Name as
349 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
352 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
354 0.78 Mon, February 23, 2009
355 * No changes from 0.77_01
357 0.77_01 Sun, February 22, 2009
359 - This package now requires its XS components. Not using
360 Sub::Name lead to different behavior and bugginess in the pure
361 Perl version of the code. A Moose test would fail when run
362 against the pure Perl version of this code.
364 * Class::MOP::Instance
365 - The inline_* methods now quote attribute names themselves, and
366 don't expect to receive a quoted value.
369 0.77 Sat, February 14, 2009
371 - Avoid assertion errors on debugging perls in is_class_loaded
375 - Fixed various corner cases where is_class_loaded incorrectly
376 returned true for a class that wasn't really loaded. (Dave
380 - Add get_all_method_names (Sartak)
381 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
383 * Class::MOP::Package
384 - Disable deprecated get_all_package_symbols in list
385 context. (Florian Ragwitz)
388 - Make sure we generate a BSD-compatible Makefile (Florian
392 - The misspelled "check_metaclass_compatability" method we've
393 kept around for backwards compat_i_bility will be removed in a
394 near future release. You've been warned.
396 0.76 Thu, January 22, 2009
397 * Class::MOP::Method::Generated
398 - Added new private methods to support code generation, which
399 are being used by Moose and can be used by MooseX
401 - Generated methods are now generated with a #line directive
402 reflecting the source of the generated method. (nothingmuch)
405 - Clarified documentation of methods that return
406 Class::MOP::Method objects. (doy)
409 - Clarified documentation of the metaclass cache methods. (Sartak)
412 - Add test showing how the xs Class::MOP::is_class_loaded can
413 be made to operate differently to the pure perl version (t0m)
415 0.75 Wed, December 31, 2008
417 - A class that was made immutable and then mutable could end up
418 sharing an immutable transformer object
419 (Class::MOP::Immutable) with other classes, leading to all
420 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
422 0.74 Tue, December 25, 2008
424 - Add an xs implementation of Class::MOP::is_class_loaded (closes
425 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
426 - Changed internals to make prehashing of hash keys easier and less
427 error-prone. (Florian Ragwitz)
429 - Fix documentation to show that around modifiers happen on both
430 sides of the modified method. (Dave Rolsky)
432 0.73 Tue, December 16, 2008
434 - Don't use Perl_mro_meta_init. It's not part of the public perl
435 api. Fixes failures to build on Win32 (RT #41750). (Florian
437 * t/082_get_code_info.t
438 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
439 munger anonymous subs when under -d and so making the tests
440 succeed in that case.
442 0.72 Mon, December 8, 2008
443 * Class::MOP::Package
444 - Pass options to _new, so subclass' attributes can be
447 - In the docs, indicate that package_name and name are required
448 when calling ->wrap (Stefan O'Rear)
450 0.71_02 Fri, December 5, 2008
451 * Class::MOP::Immutable
452 - Added a new attribute, inlined_constructor, which is true if
453 the constructor was inlined.
454 * Class::MOP::Package
455 - Make get_all_package_symbols return a hash ref in scalar
456 context and deprecate calling it in list context with a
457 warning. (Florian Ragwitz)
459 - Various improvements and refactoring, making things more robust and
460 easier to maintain. (Florian Ragwitz)
462 0.71_01 Wed, December 3, 2008
464 - Add an "execute" method to invoke the body so
465 we can avoid using the coderef overload (Sartak)
466 * Class::MOP::Immutable
467 - When we memoize methods, get their results lazily
468 to remove some compile-time cost (Sartak)
469 - Small speedup from eliminating several method
472 - Some small internal tweaks to try to reduce the number of
473 times we call get_method_map when bootstrapping the MOP. This
474 might make loading Class::MOP (and Moose) a little
475 faster. (Dave Rolsky)
476 - Implemented an optional XS version of get_method_map. Mostly
477 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
478 help form Florian Ragwitz. (Dave Rolsky)
479 - Make the behaviour of of get_all_package_symbols (and
480 therefore get_method_map) consistent for stub methods. Report
481 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
483 0.71 Wed November 26, 2008
486 - Actual package creation has moved upward from
487 Class to Module so that Moose roles can share
490 0.70_01 Mon, November 19, 2008
492 - Fixes for failures with blead (Florian Ragwitz)
493 - Silenced compiler warnings (Florian Ragwitz)
495 0.70 Fri, November 14, 2008
497 - Fixed an odd corner case where the XS version of
498 get_all_package_symbols could cause a segfault. This only
499 happened with inlined constants in Perl 5.10.0 (Florian
502 0.69 Fri, November 7, 2008
503 * Class::MOP::Method::Wrapped
504 - Added introspection methods for method modifiers (Dave Rolsky)
507 0.68 Fri October 24, 2008
509 - Make load_class require by file name instead of module name.
510 This stops confusing error messages when loading '__PACKAGE__'.
512 - Add load_one_class_of function to enable you to load one of a
513 list of classes, rather than having to call load_class multiple
514 times in an eval. (t0m)
516 0.67 Tue October 14, 2008
518 - Call a method on the class after setting the superclass list
519 so that we can get Perl to detect cycles before MRO::Compat
520 spirals into an infinite loop (sartak)
521 - Reported by Schwern, [rt.cpan.org #39001]
522 - In create(), pass unused options on to initialize()
523 - added test for this
525 0.66 Sat September 20, 2008
526 !! This release has an incompatible change regarding !!
527 introspection of a class's method with Class::MOP::Class !!
530 - We (us maintainers) now run all tests with XS and then without
531 XS, which should help us catch skew between the XS/pure Perl
535 ! The alias_method method has been deprecated. It now simply
536 calls add_method instead. There is no distinction between
537 aliased methods and "real" methods.
539 This means that methods added via alias_method now show up as
540 part of the class's method list/map. This is a backwards
541 incompatible change, but seems unlikely to break any
542 code. Famous last words. (Dave Rolsky)
545 - Fixed the spelling of "compatibility", but we still have a
546 "check_metaclass_compatability" method for backwards
549 0.65 Mon September 1, 2008
550 For those not following the series of dev releases, the changes
551 from 0.64 from 0.65 can mostly be summed up as a lot performance
552 improvements by nothingmuch, including new optional XS versions of
553 some methods. Also, Class::MOP now works _without_ any XS modules,
554 for sad systems without a compiler.
557 - Added name and package_name XS accessors, and make sure all
558 the XS and Perl versions work the same way. (Dave Rolsky)
561 - The XS versions of various methods just returned undef when
562 called class methods, rather than dying like the pure Perl
563 versions. (Dave Rolsky)
565 0.64_07 Fri August 29, 2008
567 - Silenced warnings that managed to break Moose tests when XS
568 was loaded. (Dave Rolsky)
569 - Some XS versions of methods were ignored because of typos in
570 MOP.xs. (Dave Rolsky)
572 0.64_06 Mon August 25, 2008
573 * Class::MOP (MOP.xs)
574 - Another MS VC++ fix, cannot declare a variable in the middle
575 of a scope (Taro Nishino).
577 0.64_05 Sun August 24, 2008
579 - None of the dev releases actually loaded the XS properly, but
580 we silently fell back to the pure Perl version of the
583 * Class::MOP (MOP.xs)
584 - Replaced some code that used functions not available on Visual
585 C++ with some Perl XS API bits (Dave Rolsky).
587 0.64_04 Sat August 23, 2008
589 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
591 * pod.t and pod_coveraget.t
592 - These are no longer shipped with the tarball because of bogus
593 failures from CPAN testers. (Dave Rolsky)
595 0.64_03 Thu August 21, 2008
596 * Class::MOP::Package
597 - Some (legit) code was misparsed by earlier 5.8.x
598 releases. (nothingmuch)
601 - Fix a constant in void context warning (nothingmuch)
603 0.64_02 Thu August 21, 2008
604 * Makefile.PL and Class::MOP
605 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
608 - Add missing prereqs that got lost in the switch away from
611 * Class::MOP::Instance
612 - New method - get_all_attributes (nothingmuch)
614 0.64_01 Wed August 20, 2008
616 - We now check to see if you have a compiler. If you don't, the
617 module installs without some XS bits, but will work the same
618 as with XS. This should make it easier to install on platforms
619 without a compiler (like Windows). (Dave Rolsky)
622 - Perl 6 style attribute naming replaced with sane style ('methods', not
623 '%!methods'). These changes should not impact any existing API uses.
627 - Quite a number of optimizations based on profiling, including
628 allowing constructors to take hash references instead of
629 hashes, duplicating some frequently used code in XS, and
630 making constructors immutable. These changes should not impact
631 any existing API uses. (nothingmuch)
634 - Constructors now respect the meta attributes of their subclasses,
635 facilitating MOP extensibility. More related changes will happen in the
636 next several releases. (nothingmuch)
639 - New method - get_all_methods, replaces the deprecated
640 compute_all_applicable_methods. get_all_attributes provided for
641 consistency (nothingmuch)
642 - New method - wrap_method was refactored out of get_method_map
644 - New API for meta instance invalidation - invalidate_meta_instance,
645 invalidate_meta_instances, add_dependent_meta_instance,
646 remove_dependent_meta_instance, called automatically when attribute
647 definitions change and allows notification of dependent subclasses.
650 0.64 Sun August 3, 2008
651 * Class::MOP::Immutable
652 - fixing subtle edge case in immutable when you
654 - clean up option processing (nothingmuch)
656 * Class::MOP::Instance
657 - inlined initialize slot didn't match
658 non-inlined (nothingmuch)
660 0.63 Mon July 7, 2008
662 - load_class will initialize a metaclass even if
663 the class is already loaded (sartak)
664 - load_class now returns the metaclass instance
665 instead of just 1 (sartak)
668 - better error messages (sartak and Dave Rolsky)
670 0.62 Wed June 18, 2008
671 - in is_class_loaded, recognize scalar references (as opposed to globs) in
672 the symbol table as methods (these are optimized constant subs)
674 0.61 Fri. June 13, 2008
675 - Okay, lets give this another try and see if PAUSE
676 recognizes it correct this time.
678 0.60 Thurs. Jun 12, 2008
679 - Fixed a version number issue by bumping all modules
682 0.59 Thurs. Jun 12, 2008
683 !! Several fixes resulting in yet another 25-30% speedup !!
686 - now stores the instance of the instance
687 metaclass to avoid needless recomputation
688 and deletes it when the cache is blown
689 - introduce methods to query Class::MOP::Class for
690 the options used to make it immutable as well as
691 the proper immutable transformer. (groditi)
693 * Class::MOP::Package
694 - {add, has, get, remove}_package_symbol all
695 now accept a HASH ref argument as well as the
696 string. All internal usages now use the HASH
700 - MOP.xs does sanity checks on the coderef
702 - is_class_loaded check now uses code that
703 was improved in Moose's ClassName type
705 - nonsensical (undef, empty, reference) class
706 names now throw a more direct error in
708 - tests for this and other aspects of
714 Class::MOP::Method::Wrapped
715 Class::MOP::Attribute
716 - switched usage of reftype to ref because
719 0.58 Thurs. May 29, 2008
720 (late night release engineering)--
722 - fixing the version is META.yml, no functional
723 changes in this release
725 0.57 Wed. May 28, 2008
726 !! Several speedups resulting in 20-25% speedups !!
727 || (thanks to konobi, groditi, mst & CataMoose) !!
730 - made get_method_map use list_all_package_symbols
731 instead of manually grabbing each symbol
732 - streamlining &initialize somewhat, since it gets
735 * Class::MOP::Package
736 - made {get, has}_package_symbol not call
738 - inlining a few calls to &name with
739 direct HASH access key access
740 - added get_all_package_symbols to fetch
741 a HASH of items based on a type filter
742 similar to list_all_package_symbols
743 - added tests for this
746 Class::MOP::Method::Constructor
747 Class::MOP::Method::Generated
748 Class::MOP::Method::Accessor
749 - added more descriptive error message to help
750 keep people from wasting time tracking an error
751 that is easily fixed by upgrading.
753 * Class::MOP::Immutable
754 - Don't inline a destructor unless the user actually
756 - added tests for this
758 0.56 Saturday, May 24, 2008
760 - we now get the &check_package_cache_flag
761 function from MRO::Compat
762 - All XS based functionality now has a
763 Pure Perl alternative
764 - the CLASS_MOP_NO_XS environment variable
765 can now be used to force non-XS versions

776 - added the ability to "wrap" methods when
777 making the class immutable
780 - now handling the edge case of ->meta->identifier
781 dying by wrapping add_package_symbol to specifically
782 allow for it to work.
783 - added tests for this
785 * Class::MOP::Attribute
787 Class::MOP::Immutable
788 - any time a method meta object is constructed
789 we make sure to pass the correct package and
790 method name information
793 Class::MOP::Method::Wrapped
794 Class::MOP::Method::Generated
795 Class::MOP::Method::Accessor
796 Class::MOP::Method::Consructor
797 - the &wrap constructor method now requires that a
798 'package_name' and 'name' attribute are passed. This
799 is to help support the no-XS version, and will
800 throw an error if these are not supplied.
801 - all these classes are now bootstrapped properly
802 and now store the package_name and name attributes
805 ~ Build.PL has been removed since the
806 Module::Install support has been removed
808 0.55 Mon. April 28, 2008
809 - All classes now have proper C3 MRO support
810 - added MRO::Compat as a dependency to allow
811 for the C3 MRO support to Just Work in all
815 - rebless_instance now returns the instance
816 it has just blessed, this is mostly to
818 - set the attr correctly in rebless_instance
819 when it has no init_arg
820 - tweaked &linear_isa and &class_precedence_list
821 to support c3 classes.
823 0.54 Fri. March, 14, 2008

827 passed a value from @_ or $_ to squash
828 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
831 - make_{immutable,mutable} now return 1
833 - improved error handling in ->create method
834 - rebless_instance now takes extra params which
835 will be used to populate values
836 - added tests for this
839 - localizing the Data::Dumper configurations so
840 that it does not pollute others (RT #33509)
846 Class::MOP::Attribute
847 - these classes no longer define their own ->meta,
848 but instead just inherit from Class::MOP::Object
850 * Class::MOP::Instance
851 Class::MOP::Immutable
852 - these classes now inherit from Class::MOP::Object
855 - fixed the filename length on several
856 test files so we install on VMS better
858 - fixed incorrect use of catdir when it
859 should be catfile (RT #32385)

868 to indicate that no constructor args can
869 be passed (thanks to nothingmuch)
870 - added tests for this
871 - added attribute initializer attribute (rjbs)
874 - making this use the new init_arg => undef
875 feature instead of the silly hack from
876 before (thanks to nothingmuch)
878 0.52 Tues. Jan. 22, 2008
880 - fixed bug in rebless_instance
883 * Class::MOP::Method::Constructor
884 - removed assumptions about the existence of
887 0.51 Mon. Jan. 14, 2008
888 ~~~ some misc. doc. fixes ~~~
889 ~~ updated copyright dates ~~
892 - now sets the IS_RUNNING_ON_5_10
893 constant so that we can take advantage
894 of some of the nice bits of 5.10
897 - uses the IS_RUNNING_ON_5_10 flag to
898 optimize the &linearized_isa method
899 and avoid the hack/check for circular
900 inheritence in &class_precedence_list
901 - added rebless_instance method (Sartak)
902 - added tests for this
904 * Class::MOP::Immutable
905 - the immutable class now keeps track of
906 the transformer which immutablized it
908 * Class::MOP::Instance
909 - added rebless_instance_structure method (Sartak)

926 !! Class::MOP now loads 2 x faster !!
927 !! with XS speedups (thanks konobi) !!
930 - removed the dependency on B
931 - added two XS functions (thanks konobi)
932 - get_code_info($code) which replaces all
933 the B fiddling we were doing with
934 faster/leaner XS level fiddling
935 - check_package_cache_flag($pkg_name) which
936 returns the PL_sub_generation variable to
937 be used to help manage method caching.
940 In 5.10 or greater this will actually
941 use the mro::get_pkg_gen instead to give
942 even more accurate caching information.
943 blblack++ for that stuff :)
946 - added the &subclasses method (thanks rlb)
947 - added the update_package_cache_flag and
948 reset_package_cache_flag which help keep
949 track of when we need to re-fetch the
951 - Several small improvements to take advantage
952 of the new method map caching features
954 0.48 Mon. Nov. 26, 2007
955 * Class::MOP::Attribute
956 - fixed get_read/write_method to handle the

969 pruning duplicate classes (this will be even more
970 useful in the 5.10-compat version coming soon)
972 * Class::MOP::Attribute
973 - added the get_read_method_ref and get_write_method_ref
974 methods which allow you to retrieve a CODE ref which
975 can always be used to read or write an attribute.

978 * Class::MOP::Attribute
979 - Fix error message on confess (groditi)
981 0.44 Thurs. Nov. 13, 2007

1005 - removed the relevant attributes
1007 * Class::MOP::Method::Constructor
1008 - fixed the cached values we had to be more sane
1009 - made this a subclass of Class::MOP::Method::Generated
1010 - fixed generated constructor so it properly handles
1012 - added tests for this
1013 - added the option to allow for both inlined and
1014 non-inlined constructors.
1015 - Update inlined methods for builder and predicate changes (groditi)
1017 * Class::MOP::Method::Generated
1018 - added this class as an abstract base for the
1019 Class::MOP::Method::{Constructor,Accessor} classes

1033 - alter symbol table handling to deal with 5.8.x and 5.9.x
1036 - Get rid of the crappy workaround from 0.40/41
1038 0.41 Sun. July 15, 2007
1040 Arghh!!! My TODO test didn't work, so I handle
1041 it manually now so that people can use this
1042 with 5.9.5/bleadperl without issue.
1044 0.40 Tues, July 3, 2007
1046 ~ marked a test in 003_methods.t as TODO
1047 for perl 5.9.5 (this test is irrelvant to
1048 the module functioning on 5.9.5 for the most
1051 0.39 Mon. June 18, 2007
1052 * Class::MOP::Immutable
1053 - added make_metaclass_mutable + docs (groditi)
1054 - removed unused variable
1055 - added create_immutable_transformer
1056 necessary for sane overloading of immutable behavior
1057 - tests for this (groditi)
1060 - Immutability can now be undone,
1061 added make_mutable + tests + docs (groditi)
1062 - Massive changes to the way Immutable is done
1063 for details see comments next to make_immutable
1064 This fixes a bug where custom metaclasses broke
1065 when made immutable. We are now keeping one immutable
1066 metaclass instance per metaclass instead of just one
1067 to prevent isa hierarchy corruption. Memory use will go
1068 up, but I suspect it will be neglible.
1069 - New tests added for this behavior. (groditi)
1071 0.38 Thurs. May 31, 2007
1072 ~~ More documentation updates ~~
1074 * Class::MOP::Package
1075 - we now deal with stub methods properly

1080 - added get_read_method and get_write_method
1081 thanks to groditi for this code, tests
1083 - added tests and POD for this
1086 - fixed RT issue #27329, clone object now
1087 handles undef values correctly.
1088 - added tests for this
1089 - Corrected anon-class handling so that they
1090 will not get reaped when instances still
1091 exist which need to reference them. This is
1092 the correct behavior, hopefully this is an
1093 obscure enough feature that there are not too
1094 many work arounds out in the wild.
1095 - added tests for this by groditi
1096 - updated docs to explain this
1099 - load custom metaclasses automatically (thanks groditi)
1100 - added tests for this behavior
1102 0.37 Sat. March 10, 2007

1109 * Class::MOP::Attribute
1110 - default now checks the instance with defined to
1111 avoid setting off bool-overloads (found by Carl Franks)
1115 - bad name in a test, causing meaningless failuress.
1120 ~~ GLOBAL CHANGES ~~
1121 - All attribute names are now consistent and follow Perl 6
1122 style (prefixed with the sigil, and ! as the twigil for
1123 private attrs). This should not affect any code, unless
1124 you broke encapsulation, in which case, it is your problem
1127 !! Class::MOP::Class::Immutable has been removed
1129 * Class::MOP::Method::Constructor
1130 - this has been moved out of Class::MOP::Class::Immutable
1131 and is a proper subclass of Class::MOP::Method now.
1134 - this module now uses Class::MOP::Immutable for the
1135 immutable transformation instead of
1136 Class::MOP::Class::Immutable.
1138 + Class::MOP::Immutable
1139 - this module now controls the transformation from a mutable
1140 to an immutable version of the class. Docs for this will
1141 be coming eventually.
1144 0.36 Sun. Nov. 5, 2006
1146 - added a few 'no warnings' lines to keep annoying
1147 (and meaningless) warnings from chirping during
1151 - some more bootstrapping is now done on the new
1154 * Class::MOP::Class::Immutable
1156 - constructor generation is now handled by
1157 the Class::MOP::Method::Constructor class
1159 * Class::MOP::Method::Constructor
1160 - created this to handle constructor generation
1161 in Class::MOP::Class::Immutable
1163 * Class::MOP::Attribute
1165 - attributes now delegate to the
1166 Class::MOP::Method::Accessor to generate
1169 * Class::MOP::Method::Accessor
1170 - all accessor generation functions from
1171 Class::MOP::Attribute have been moved here
1173 0.35 Sat. Sept. 30, 2006

1176 - initial prototype of a class browser, more
1177 on this to come. Comments and patches are
1181 - All Class::MOP::* accessors are no longer
1182 re-generated in the bootstrap, instead
1183 they are aliased from the originals

1185 - added Class::MOP::Method (and its subclasses)
1187 - adjusted tests for this
1188 - added the Class::MOP::Instance attributes

1195 - adjusted tests to compensate
1196 - adjusted docs for this
1199 - changed how methods are dealt with to
1200 encapsulate most of the work into the
1201 &get_method_map method
1202 - made several adjustments for the change
1203 in Class::MOP::Method
1204 - &add_attribute now checks if you are adding
1205 a duplicate name, and properly removes the
1206 old one before installing the new one
1207 - added tests for this
1208 - adjusted docs for this
1210 * Class::MOP::Class::Immutable
1211 - added caching of &get_method_map
1212 - fixed issue with &get_package_symbol
1213 - cleaned up the methods that die (patch by David Wheeler)

1217 &list_all_package_symbols
1219 0.34 Sat. Aug. 26, 2006
1221 - added the %:methods attribute, which like
1222 the $:version and such just actually goes
1223 to the symbol table to get it's stuff.
1224 However, it makes the MOP more complete.
1226 - The &create method now requires that all
1227 but the package name now is passed in as
1228 named parameters. See docs for more info.
1229 - updated docs and tests for this
1231 * Class::MOP::Object
1232 - added &dump method to easily Data::Dumper

1254 are no longer allowed for defaults
1255 - added tests for this
1257 * Class::MOP::Package
1258 - fixed an issue with perl 5.8.1 and how it deals
1259 with symbol tables. The namespace hash is now
1260 always reloaded from the symbol table.
1262 ~ lots of misc. documentation cleanup
1264 0.32 Sat. Aug. 12, 2006
1265 + added Class::MOP::Object so that the
1266 metamodel is more complete (and closer
1267 to what Perl 6 will probably be).

1271 the primary gateway between the metaclass
1272 and the Perl 5 symbol table
1273 - added many tests for this
1274 - this class is now a subclass of
1276 - added some tests to reflect this

1280 use Class::MOP::Package methods instead
1282 * Class::MOP::Module
1283 - adding the $:version attribute in the bootstrap
1284 so that Module has a version as an attribute
1285 - see comment in Class::MOP for details
1286 - added the $:authority attribute to this module
1287 as well as an &identifier method, to bring us
1288 ever closer to Perl 6 goodness
1289 - I have added $AUTHORITY to all the modules
1290 - added tests for this

1306 anywhere within the class hierarchy
1308 * Class::MOP::Attribute
1309 - added &set_value and &get_value for getting
1310 the value of the attribute for a particular
1313 0.30 Wed. July 5, 2006
1314 ---------------------------------------
1315 This is the first version of Class::MOP
1316 to introduce the immutable features which
1317 will be used for optimizating the MOP.
1318 This support should still be considered
1319 experimental, but moving towards stability.
1320 ---------------------------------------
1322 * Created Class::MOP::Class::Immutable
1324 * Created the Class::MOP::Package and
1325 Class::MOP::Module classes to more
1326 closely conform to Perl 6's meta-model
1329 - now inherits from Class::MOP::Module
1330 - several methods moved to ::Module and
1331 ::Package and now inherited
1332 - added tests for this
1334 * Class::MOP::Instance
1335 - added an is_inlinable method to allow other
1336 classes to check before they attempt to optimize.
1337 - added an inline_create_instance to inline
1338 instance creation (of course)
1341 - the Class::MOP::Class::*_package_variable
1342 methods are all now methods of Class::MOP::Package
1343 and called *_package_symbol instead. This is
1344 because they are now more general purpose symbol
1345 table manipulation methods.
1347 0.29_02 Thurs. June 22, 2006
1348 ++ DEVELOPER RELEASE ++
1350 - small change in &create so that it behaves

1402 - added tests for this
1403 - added get_all_metaclasses, get_all_metaclass_names
1404 and get_all_metaclass_instances method to allow
1405 access to all the cached metaclass objects.
1406 - attribute slot initialization is now the responsibility
1407 of the attribute itself, and construct_instance now
1408 delegates appropriately
1410 * Class::MOP::Attribute

1412 of the attribute itself, so we added a method for it
1413 called initialize_instance_slot

1442 0.21 Wed. March 15, 2006
1444 - fixed issue where metaclasses are reaped from

1458 * Class::MOP::Method::Wrapped
1459 - allows for a method to be wrapped with
1460 before, after and around modifiers
1461 - added tests and docs for this feature
1464 - improved &get_package_symbol
1465 - &version and &superclasses now use it
1466 - methods are now blessed into Class::MOP::Method
1468 - added methods to install CLOS-style method modifiers
1469 - &add_before_method_modifier
1470 - &add_after_method_modifier
1471 - &add_around_method_modifier
1472 - added tests and docs for these
1473 - added &find_next_method_by_name which finds the

1476 0.12 Thurs. Feb 23, 2006
1477 - reduced the dependency on B, no need to always
1481 - added docs to the C3 method dispatch order test
1482 - fixed missing Algorithm::C3 dependency by making
1483 the test skip if it is not installed
1485 0.11 Mon Feb. 20, 2006
1487 - added example of changing method dispatch order to C3
1490 - changed how clone_instance behaves, it now only does a
1491 shallow clone (see docs for more details)
1492 - added docs and tests
1494 0.10 Tues Feb. 14, 2006
1495 ** This release was mostly about writing more tests and
1496 cleaning out old and dusty code, the MOP should now
1497 be considered "ready to use".
1499 - adding more tests to get coverage up a little higher,
1500 mostly testing errors and edge cases.
1501 - test coverage is now at 99%
1504 - no longer optionally exports to UNIVERSAL::meta or
1505 creates a custom metaclass generator, use the
1506 metaclass pragma instead.
1509 - fixed a number of minor issues which came up in the
1510 error/edge-case tests
1512 * Class::MOP::Attribute
1513 - fixed a number of minor issues which came up in the
1514 error/edge-case tests
1517 - fixing the AttributesWithHistory example, it was broken.
1519 0.06 Thurs Feb. 9, 2006
1521 - adding new metaclass pragma to make setting up the
1522 metaclass a little more straightforward
1525 - clean up bootstrapping to include more complete
1526 attribute definitions for Class::MOP::Class and
1527 Class::MOP::Attribute (accessors, readers, writers,
1528 etc.) ... it is redundant, but is useful meta-info
1532 - fixing minor meta-circularity issue with &meta, it
1533 is now more useful for subclasses
1534 - added &get_attribute_map as an accessor for the
1535 hash of attribute meta objects
1536 - &compute_all_applicable_attributes now just returns
1537 the attribute meta-object, rather than the HASH ref
1538 since all the same info can be gotten from the
1539 attribute meta-object itself
1540 - updated docs & tests to reflect
1541 - added &clone_instance method which does a deep clone
1542 of the instance structure created by &construct_instance
1543 - added docs & tests for this
1544 - added Clone as a dependency
1545 - added &new_object and &clone_object convience methods to
1546 return blessed new or cloned instances
1547 - they handle Class::MOP::Class singletons correctly too
1548 - added docs & tests for this
1549 - cleaned up the &constuct_class_instance so that it behaves
1550 more like &construct_instance (and managed the singletons too)
1551 - added the &check_metaclass_compatibility method to make sure
1552 that metaclasses are upward and downward compatible.
1553 - added tests and docs for this
1556 - adjusting code to use the &Class::MOP::Class::meta
1558 - adjusting code to use the metaclass pragma
1560 0.05 Sat Feb. 4, 2006
1562 - added the &attribute_metaclass and &method_metaclass
1563 attributes which contain a metaclass name to use for
1564 attributes/methods respectively
1567 - bootstrap additional attributes for Class::MOP::Class
1570 - adjusted the example code and tests to use the new
1571 &attribute_metaclass feature of Class::MOP::Class
1572 - added new example:
1575 0.04 Fri Feb. 3, 2006
1577 - some documentation suggestions from #perl6
1579 * Class::MOP::Attribute
1580 - improved error messages

1595 - refactored the InsideOut example to take advantage
1596 of the Class::MOP::Attribute refactoring
1597 - changed example files to .pod files and hide thier
1598 package names from PAUSE (I don't want to own these
1599 namespaces really, they are just examples)
1601 0.02 Thurs Feb. 2, 2006
1602 - moving examples from t/lib/* to examples/*
1603 - adding POD documentation to the examples
