1 Revision history for Perl extension Class-MOP.
5 - Applied an MS VC++ compilation fix from Taro Nishino. RT #48072
7 0.92_01 Thu, Sep 10, 2009
9 - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
12 - Make sure XS code handles magical scalars correctly. (Goro Fuji)
15 - Documented the immutable_options method, which is useful if you need
16 to make a class mutable temporarily, and then nede to restore
17 immutability. (Dave Rolsky)
20 - Deprecated features have been moved to their own module,
21 Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)
26 - Move get_method_map and its various scaffolding into Package. (hdp)
29 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
30 the first argument, rather than just a coderef. (doy)
32 * Class::MOP::Attribute
34 - Allow attribute names to be false (while still requiring them to be
38 * Class::MOP::Method::Wrapped
39 - Fixing variable usage issues with the patch from previous
40 version, not properly using lexicals in the for
44 Japan Perl Association has sponsored Goro Fuji to improve startup
45 performance of Class::MOP and Moose. These enhancements may break
46 backwards compatibility if you're doing (or using) complex
47 metaprogramming, so, as always, test your code!
48 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
52 - Anonymous classes were not completely destroyed when they went
53 out of scope, leading to a memory leak. RT #47480. (Goro
57 - The get_method, has_method, and add_method methods no longer
58 use get_method_map. Method objects are instantiated
59 lazily. This significantly improves Class::MOP's load
63 - Inline fewer metaclass-level constructors since the ones we
64 have are perfectly fine. This reduces the number of string
67 * Class::MOP::Method::Wrapped
68 - If a method modifier set $_, this caused the modifier to blow
69 up, because of some weird internals. (Jeremy Stashewsky)
73 * Class::MOP::Class::Immutable::Trait
74 - Made the Trait act like a role with a bunch of "around"
75 modifiers, rather than sticking it in the inheritance
76 hierarchy. This fixes various problems that caused with
77 metaclass compatibility, which broke Fey::ORM.
80 - Allow a blessed code reference as the method body. Fixes a
81 problem interaction with MooseX::Types. (ash)
83 * Class::MOP::Instance
84 - add inline version of rebless_instance_structure. (doy)
85 - change inline_slot_access to use single quotes (gphat)
87 0.88 Tue, Jun 23, 2009
89 - Moved the __INSTANCE__ parameter to _construct_instance from
91 - Fixed some issues involving metaclasses of metaclasses and
94 0.87 Sun, Jun 21, 2009
96 - Made sure to always local-ize $@ and $SIG{__DIE__} before
97 calling an eval. Fixes RT #45973.
100 - Synced docs about immutability with the current reality (which
101 changed back in 0.82_01)
102 - Removed the immutable_transformer method, which had been
103 returning undef since 0.82_01 anyway.
106 - Got rid of tests which needed Moose and improved testing of
107 constructor/destructor inlining warnings. Fixes RT #47119.
109 0.86 Tue, Jun 16, 2009
111 - If you redefined a subroutine at runtime and then wrapped it
112 with a method modifier, the modifier could in some cases wrap
113 the original version of the subroutine. Fixes RT #46957.
116 - make_immutable issues a warning instead of overriding an
117 existing DESTROY method (Dylan William Hardison). Fixes RT
120 0.85 Sat, Jun 6, 2009
121 * Class::MOP::Attribute
122 - Allow default values to be Class::MOP::Methods. (Florian
124 - Test the above. (Rhesa Rozendaal)
125 - Tweak original commit so the intent matches the accepted
126 behavior (Nicholas Perez)
129 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
132 - Add direct_subclasses method (Sartak)
133 - Tests for subclasses and direct_subclasses (Sartak)
134 - subname is no longer used unconditionally in add_method, but
135 only if the code reference's name is '__ANON__' (nothingmuch)
136 - Add a hook for _superclasses_updated (Sartak)
139 - Remove long, old warning about possibly outdated modules
142 0.84 Tue, May 12, 2009
144 - Depend on Text::Exception 0.27 to avoid failing tests ond old
148 - Made is_class_loaded a little stricter. It was reporting that
149 a class was loaded if it merely had an @ISA variable in its
150 stash. Now it checks that the @ISA var has elements in it.
151 - Deprecate in_global_destruction and subname re-exporting
155 - Explicitly use Devel::GlobalDestruction and Sub::Name
158 * Class::MOP::Package
159 - Disable prototype mismatch warnings for add_package_symbol.
162 - Add test for finding methods from $meta->name->meta before immutable,
165 0.83 Mon, April 27, 2009
167 - Fix segfault when calling get_method_map on a metaclass for an empty
170 0.82_02 Fri, April 24, 2009
171 * Class::MOP::Method::Inlined
172 - Don't inline if the expected method is not defined at all (happens with
173 e.g. Moose::Object::_new is the expected method due to an overridden
176 - Some tests were trying to load Class::MOP::Immutable, which
177 was removed in 0.82_01.
179 0.82_01 Thu, April 23, 2009
180 * Class::MOP::Immutable (and others)
181 - Refactor the immutability system to use a pre-defined class
182 for the immutable metaclass of Class::MOP::Class::Immutable::$class
183 - Rather than generating methods into this class every time, use
184 a Trait (basic mixin) to supply the cached methods
185 - Remove the hack that returns the mutable metaclass for
186 metacircularity in order to provide consistent meta-metaclasses
187 for the Moose compatibility handling code
188 (mst broke it, nothingmuch fixed it)
190 0.82 Mon, April 20, 2009
192 - The deprecation wrappers for some renamed methods were not
193 passing arguments to the new method. (nothingmuch)
195 * Class::MOP::Immutable
196 - Warn during immutablization if the local class provides its own
197 constructor, to parallel the warning in Moose when a superclass
198 provides its own constructor (doy)
200 0.81 Tue, April 7, 2009
203 * Class::MOP::Instance
204 * Class::MOP::Attribute
205 * Class::MOP::Method::Accessor
206 * Class::MOP::Method::Constructor
207 - Include stack traces in the deprecation warnings introduced in
208 0.80_01. (Florian Ragwitz)
211 - Avoid c compiler warnings by declaring some unused function
212 arguments. (Florian Ragwitz)
214 0.80_01 Sun, April 5, 2009
216 - Make sure to preserve any compiler flags already defined in
217 Config.pm. Patch by Vincent Pit. RT #44739.
219 * Many methods have been renamed with a leading underscore, and a
220 few have been deprecated entirely. The methods with a leading
221 underscore are consider "internals only". People writing
222 subclasses or extensions to Class::MOP should feel free to
223 override them, but they are not for "public" use.
226 - construct_class_instance => _construct_class_instance (use new_object)
227 - construct_instance => _construct_instance (use new_object)
228 - check_metaclass_compatibility => _check_metaclass_compatibility
229 - create_meta_instance => _create_meta_instance (use get_meta_instance)
230 - clone_instance => _clone_instance (use clone_object)
231 - compute_all_applicable_methods is deprecated, use get_all_methods
232 - compute_all_applicable_attributes is deprecated, use get_all_attributes
234 - Class::MOP::Instance
235 - bless_instance_structure is deprecated and will be removed
239 - create has been renamed to _instantiate_module. This method
240 does not construct an object, it evals some code that
241 creates the relevant package in Perl's symbol table.
243 - Class::MOP::Method::Accessor
244 - initialize_body => _initialize_body (this is always called
245 when an object is constructed)
246 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
248 - Class::MOP::Method::Constructor
249 - initialize_body => _initialize_body (this is always called
250 when an object is constructed)
251 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
252 - attributes => _attributes
253 - meta_instance => _meta_instance
255 0.80 Wed, April 1, 2009
257 - Call user_class->meta in fewer places, with the eventual goal
258 of allowing the user to rename or exclude ->meta
259 altogether. Instead uses Class::MOP::class_of. (Sartak)
262 - New class_of function that should be used to retrieve a
263 metaclass. This is unlike get_metaclass_by_name in that it
264 accepts instances, not just class names. (Sartak)
267 - load_first_existing_class didn't actually load the first
268 existing class; instead, it loaded the first existing and
269 compiling class. It now throws an error if a class exists (in
270 @INC) but fails to compile. (hdp)
274 - we had some semi-buggy code that purported to provide a
275 HAS_ISAREV based on whether mro had get_isarev (due to an
276 oversight, it always returned 1). Since mro and MRO::Compat
277 have always had get_isarev, HAS_ISAREV was pointless. This
278 insight simplified the subclasses method by deleting the
279 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
281 0.79 Fri, March 29, 2009
282 * No changes from 0.78_02.
284 0.78_02 Thu, March 26, 2009
286 * Class::MOP::Immutable
287 - A big backwards-incompatible refactoring of the Immutable API,
288 and the make_immutable/make_mutable pieces of the Class
289 API. The core __PACKAGE__->meta->make_immutable API remains
290 the same, however, so this should only affect the most
294 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
295 has been fixed to be backwards compatible with 5.8.x.
298 - Add a hook for rebless_instance_away (Sartak)
299 - Use blessed instead of ref to get an instance's class name
300 in rebless_instance. (Sartak)
302 0.78_01 Wed, March 18, 2009
304 - Revised and reorganized all of the API documentation. All
305 classes now have (more or less) complete API documentation.
308 * Class::MOP::Instance
309 - Reblessing into a package that supports overloading wasn't
310 properly adding overload magic to the object due to a bug
311 in (at least) 5.8.8. We now use $_[1] directly which seems
312 to set the magic properly. (Sartak)
314 * Class::MOP::Attribute
315 - The process_accessors method is now private. A public alias
316 exists (and will stick around for a few releases), but it
317 warns that calling the public method is deprecated.
319 * Class::MOP::Method::Generated
320 - Removed the new and _new methods, since this is an abstract
321 base class, and all existing subclasses implement their own
325 - Stop is_class_loaded from thinking a class is loaded if it
326 only has an empty GV (Florian Ragwitz).
327 - Add a test for this (Yappo).
328 - Refactor get_all_package_symbols to allow short-circuiting
330 - Use this in is_class_loaded (Florian Ragwitz).
331 - Stop segfaulting when trying to get the name from a sub that's
332 still being compiled (Florian Ragwitz).
333 - Add tests for this (Florian Ragwitz).
334 - Prefix all public symbols with "mop_" (Florian Ragwitz).
335 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
336 - Simplify creating simple xs reader methods (Florian Ragwitz).
337 - Make everything compile with c++ compilers (Florian Ragwitz).
338 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
341 - Remove optional test plans for tests depending on Sub::Name as
342 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
345 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
347 0.78 Mon, February 23, 2009
348 * No changes from 0.77_01
350 0.77_01 Sun, February 22, 2009
352 - This package now requires its XS components. Not using
353 Sub::Name lead to different behavior and bugginess in the pure
354 Perl version of the code. A Moose test would fail when run
355 against the pure Perl version of this code.
357 * Class::MOP::Instance
358 - The inline_* methods now quote attribute names themselves, and
359 don't expect to receive a quoted value.
362 0.77 Sat, February 14, 2009
364 - Avoid assertion errors on debugging perls in is_class_loaded
368 - Fixed various corner cases where is_class_loaded incorrectly
369 returned true for a class that wasn't really loaded. (Dave
373 - Add get_all_method_names (Sartak)
374 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
376 * Class::MOP::Package
377 - Disable deprecated get_all_package_symbols in list
378 context. (Florian Ragwitz)
381 - Make sure we generate a BSD-compatible Makefile (Florian
385 - The misspelled "check_metaclass_compatability" method we've
386 kept around for backwards compat_i_bility will be removed in a
387 near future release. You've been warned.
389 0.76 Thu, January 22, 2009
390 * Class::MOP::Method::Generated
391 - Added new private methods to support code generation, which
392 are being used by Moose and can be used by MooseX
394 - Generated methods are now generated with a #line directive
395 reflecting the source of the generated method. (nothingmuch)
398 - Clarified documentation of methods that return
399 Class::MOP::Method objects. (doy)
402 - Clarified documentation of the metaclass cache methods. (Sartak)
405 - Add test showing how the xs Class::MOP::is_class_loaded can
406 be made to operate differently to the pure perl version (t0m)
408 0.75 Wed, December 31, 2008
410 - A class that was made immutable and then mutable could end up
411 sharing an immutable transformer object
412 (Class::MOP::Immutable) with other classes, leading to all
413 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
415 0.74 Tue, December 25, 2008
417 - Add an xs implementation of Class::MOP::is_class_loaded (closes
418 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
419 - Changed internals to make prehashing of hash keys easier and less
420 error-prone. (Florian Ragwitz)
422 - Fix documentation to show that around modifiers happen on both
423 sides of the modified method. (Dave Rolsky)
425 0.73 Tue, December 16, 2008
427 - Don't use Perl_mro_meta_init. It's not part of the public perl
428 api. Fixes failures to build on Win32 (RT #41750). (Florian
430 * t/082_get_code_info.t
431 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
432 munger anonymous subs when under -d and so making the tests
433 succeed in that case.
435 0.72 Mon, December 8, 2008
436 * Class::MOP::Package
437 - Pass options to _new, so subclass' attributes can be
440 - In the docs, indicate that package_name and name are required
441 when calling ->wrap (Stefan O'Rear)
443 0.71_02 Fri, December 5, 2008
444 * Class::MOP::Immutable
445 - Added a new attribute, inlined_constructor, which is true if
446 the constructor was inlined.
447 * Class::MOP::Package
448 - Make get_all_package_symbols return a hash ref in scalar
449 context and deprecate calling it in list context with a
450 warning. (Florian Ragwitz)
452 - Various improvements and refactoring, making things more robust and
453 easier to maintain. (Florian Ragwitz)
455 0.71_01 Wed, December 3, 2008
457 - Add an "execute" method to invoke the body so
458 we can avoid using the coderef overload (Sartak)
459 * Class::MOP::Immutable
460 - When we memoize methods, get their results lazily
461 to remove some compile-time cost (Sartak)
462 - Small speedup from eliminating several method
465 - Some small internal tweaks to try to reduce the number of
466 times we call get_method_map when bootstrapping the MOP. This
467 might make loading Class::MOP (and Moose) a little
468 faster. (Dave Rolsky)
469 - Implemented an optional XS version of get_method_map. Mostly
470 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
471 help form Florian Ragwitz. (Dave Rolsky)
472 - Make the behaviour of of get_all_package_symbols (and
473 therefore get_method_map) consistent for stub methods. Report
474 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
476 0.71 Wed November 26, 2008
479 - Actual package creation has moved upward from
480 Class to Module so that Moose roles can share
483 0.70_01 Mon, November 19, 2008
485 - Fixes for failures with blead (Florian Ragwitz)
486 - Silenced compiler warnings (Florian Ragwitz)
488 0.70 Fri, November 14, 2008
490 - Fixed an odd corner case where the XS version of
491 get_all_package_symbols could cause a segfault. This only
492 happened with inlined constants in Perl 5.10.0 (Florian
495 0.69 Fri, November 7, 2008
496 * Class::MOP::Method::Wrapped
497 - Added introspection methods for method modifiers (Dave Rolsky)
500 0.68 Fri October 24, 2008
502 - Make load_class require by file name instead of module name.
503 This stops confusing error messages when loading '__PACKAGE__'.
505 - Add load_one_class_of function to enable you to load one of a
506 list of classes, rather than having to call load_class multiple
507 times in an eval. (t0m)
509 0.67 Tue October 14, 2008
511 - Call a method on the class after setting the superclass list
512 so that we can get Perl to detect cycles before MRO::Compat
513 spirals into an infinite loop (sartak)
514 - Reported by Schwern, [rt.cpan.org #39001]
515 - In create(), pass unused options on to initialize()
516 - added test for this
518 0.66 Sat September 20, 2008
519 !! This release has an incompatible change regarding !!
520 introspection of a class's method with Class::MOP::Class !!
523 - We (us maintainers) now run all tests with XS and then without
524 XS, which should help us catch skew between the XS/pure Perl
528 ! The alias_method method has been deprecated. It now simply
529 calls add_method instead. There is no distinction between
530 aliased methods and "real" methods.
532 This means that methods added via alias_method now show up as
533 part of the class's method list/map. This is a backwards
534 incompatible change, but seems unlikely to break any
535 code. Famous last words. (Dave Rolsky)
538 - Fixed the spelling of "compatibility", but we still have a
539 "check_metaclass_compatability" method for backwards
542 0.65 Mon September 1, 2008
543 For those not following the series of dev releases, the changes
544 from 0.64 from 0.65 can mostly be summed up as a lot performance
545 improvements by nothingmuch, including new optional XS versions of
546 some methods. Also, Class::MOP now works _without_ any XS modules,
547 for sad systems without a compiler.
550 - Added name and package_name XS accessors, and make sure all
551 the XS and Perl versions work the same way. (Dave Rolsky)
554 - The XS versions of various methods just returned undef when
555 called class methods, rather than dying like the pure Perl
556 versions. (Dave Rolsky)
558 0.64_07 Fri August 29, 2008
560 - Silenced warnings that managed to break Moose tests when XS
561 was loaded. (Dave Rolsky)
562 - Some XS versions of methods were ignored because of typos in
563 MOP.xs. (Dave Rolsky)
565 0.64_06 Mon August 25, 2008
566 * Class::MOP (MOP.xs)
567 - Another MS VC++ fix, cannot declare a variable in the middle
568 of a scope (Taro Nishino).
570 0.64_05 Sun August 24, 2008
572 - None of the dev releases actually loaded the XS properly, but
573 we silently fell back to the pure Perl version of the
576 * Class::MOP (MOP.xs)
577 - Replaced some code that used functions not available on Visual
578 C++ with some Perl XS API bits (Dave Rolsky).
580 0.64_04 Sat August 23, 2008
582 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
584 * pod.t and pod_coveraget.t
585 - These are no longer shipped with the tarball because of bogus
586 failures from CPAN testers. (Dave Rolsky)
588 0.64_03 Thu August 21, 2008
589 * Class::MOP::Package
590 - Some (legit) code was misparsed by earlier 5.8.x
591 releases. (nothingmuch)
594 - Fix a constant in void context warning (nothingmuch)
596 0.64_02 Thu August 21, 2008
597 * Makefile.PL and Class::MOP
598 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
601 - Add missing prereqs that got lost in the switch away from
604 * Class::MOP::Instance
605 - New method - get_all_attributes (nothingmuch)
607 0.64_01 Wed August 20, 2008
609 - We now check to see if you have a compiler. If you don't, the
610 module installs without some XS bits, but will work the same
611 as with XS. This should make it easier to install on platforms
612 without a compiler (like Windows). (Dave Rolsky)
615 - Perl 6 style attribute naming replaced with sane style ('methods', not
616 '%!methods'). These changes should not impact any existing API uses.
620 - Quite a number of optimizations based on profiling, including
621 allowing constructors to take hash references instead of
622 hashes, duplicating some frequently used code in XS, and
623 making constructors immutable. These changes should not impact
624 any existing API uses. (nothingmuch)
627 - Constructors now respect the meta attributes of their subclasses,
628 facilitating MOP extensibility. More related changes will happen in the
629 next several releases. (nothingmuch)
632 - New method - get_all_methods, replaces the deprecated
633 compute_all_applicable_methods. get_all_attributes provided for
634 consistency (nothingmuch)
635 - New method - wrap_method was refactored out of get_method_map
637 - New API for meta instance invalidation - invalidate_meta_instance,
638 invalidate_meta_instances, add_dependent_meta_instance,
639 remove_dependent_meta_instance, called automatically when attribute
640 definitions change and allows notification of dependent subclasses.
643 0.64 Sun August 3, 2008
644 * Class::MOP::Immutable
645 - fixing subtle edge case in immutable when you
647 - clean up option processing (nothingmuch)
649 * Class::MOP::Instance
650 - inlined initialize slot didn't match
651 non-inlined (nothingmuch)
653 0.63 Mon July 7, 2008
655 - load_class will initialize a metaclass even if
656 the class is already loaded (sartak)
657 - load_class now returns the metaclass instance
658 instead of just 1 (sartak)
661 - better error messages (sartak and Dave Rolsky)
663 0.62 Wed June 18, 2008
664 - in is_class_loaded, recognize scalar references (as opposed to globs) in
665 the symbol table as methods (these are optimized constant subs)
667 0.61 Fri. June 13, 2008
668 - Okay, lets give this another try and see if PAUSE
669 recognizes it correct this time.
671 0.60 Thurs. Jun 12, 2008
672 - Fixed a version number issue by bumping all modules
675 0.59 Thurs. Jun 12, 2008
676 !! Several fixes resulting in yet another 25-30% speedup !!
679 - now stores the instance of the instance
680 metaclass to avoid needless recomputation
681 and deletes it when the cache is blown
682 - introduce methods to query Class::MOP::Class for
683 the options used to make it immutable as well as
684 the proper immutable transformer. (groditi)
686 * Class::MOP::Package
687 - {add, has, get, remove}_package_symbol all
688 now accept a HASH ref argument as well as the
689 string. All internal usages now use the HASH
693 - MOP.xs does sanity checks on the coderef
695 - is_class_loaded check now uses code that
696 was improved in Moose's ClassName type
698 - nonsensical (undef, empty, reference) class
699 names now throw a more direct error in
701 - tests for this and other aspects of
707 Class::MOP::Method::Wrapped
708 Class::MOP::Attribute
709 - switched usage of reftype to ref because
712 0.58 Thurs. May 29, 2008
713 (late night release engineering)--
715 - fixing the version is META.yml, no functional
716 changes in this release
718 0.57 Wed. May 28, 2008
719 !! Several speedups resulting in 20-25% speedups !!
720 || (thanks to konobi, groditi, mst & CataMoose) !!
723 - made get_method_map use list_all_package_symbols
724 instead of manually grabbing each symbol
725 - streamlining &initialize somewhat, since it gets
728 * Class::MOP::Package
729 - made {get, has}_package_symbol not call
731 - inlining a few calls to &name with
732 direct HASH access key access
733 - added get_all_package_symbols to fetch
734 a HASH of items based on a type filter
735 similar to list_all_package_symbols
736 - added tests for this
739 Class::MOP::Method::Constructor
740 Class::MOP::Method::Generated
741 Class::MOP::Method::Accessor
742 - added more descriptive error message to help
743 keep people from wasting time tracking an error
744 that is easily fixed by upgrading.
746 * Class::MOP::Immutable
747 - Don't inline a destructor unless the user actually
749 - added tests for this
751 0.56 Saturday, May 24, 2008
753 - we now get the &check_package_cache_flag
754 function from MRO::Compat
755 - All XS based functionality now has a
756 Pure Perl alternative
757 - the CLASS_MOP_NO_XS environment variable
758 can now be used to force non-XS versions
761 * Class::MOP::Attribute

764 anon-sub ref in the method metaclass when
766 - added tests for this
768 * Class::MOP::Immutable
769 - added the ability to "wrap" methods when
770 making the class immutable
773 - now handling the edge case of ->meta->identifier
774 dying by wrapping add_package_symbol to specifically
775 allow for it to work.
776 - added tests for this
778 * Class::MOP::Attribute
780 Class::MOP::Immutable
781 - any time a method meta object is constructed
782 we make sure to pass the correct package and
783 method name information
786 Class::MOP::Method::Wrapped
787 Class::MOP::Method::Generated
788 Class::MOP::Method::Accessor
789 Class::MOP::Method::Consructor
790 - the &wrap constructor method now requires that a
791 'package_name' and 'name' attribute are passed. This
792 is to help support the no-XS version, and will
793 throw an error if these are not supplied.
794 - all these classes are now bootstrapped properly
795 and now store the package_name and name attributes
798 ~ Build.PL has been removed since the
799 Module::Install support has been removed
801 0.55 Mon. April 28, 2008
802 - All classes now have proper C3 MRO support
803 - added MRO::Compat as a dependency to allow
804 for the C3 MRO support to Just Work in all
808 - rebless_instance now returns the instance
809 it has just blessed, this is mostly to
811 - set the attr correctly in rebless_instance
812 when it has no init_arg
813 - tweaked &linear_isa and &class_precedence_list
814 to support c3 classes.
816 0.54 Fri. March, 14, 2008
819 - making sure that load_class never gets
820 passed a value from @_ or $_ to squash
821 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
824 - make_{immutable,mutable} now return 1
826 - improved error handling in ->create method
827 - rebless_instance now takes extra params which
828 will be used to populate values
829 - added tests for this
832 - localizing the Data::Dumper configurations so
833 that it does not pollute others (RT #33509)
839 Class::MOP::Attribute
840 - these classes no longer define their own ->meta,
841 but instead just inherit from Class::MOP::Object
843 * Class::MOP::Instance
844 Class::MOP::Immutable
845 - these classes now inherit from Class::MOP::Object
848 - fixed the filename length on several
849 test files so we install on VMS better
851 - fixed incorrect use of catdir when it
852 should be catfile (RT #32385)
854 0.53 Thurs. Feb. 14, 1008
855 ~~ several doc. fixes and updates ~~
858 Class::MOP::Method::Constructor

861 to indicate that no constructor args can
862 be passed (thanks to nothingmuch)
863 - added tests for this
864 - added attribute initializer attribute (rjbs)
867 - making this use the new init_arg => undef
868 feature instead of the silly hack from
869 before (thanks to nothingmuch)
871 0.52 Tues. Jan. 22, 2008
873 - fixed bug in rebless_instance
876 * Class::MOP::Method::Constructor
877 - removed assumptions about the existence of
880 0.51 Mon. Jan. 14, 2008
881 ~~~ some misc. doc. fixes ~~~
882 ~~ updated copyright dates ~~
885 - now sets the IS_RUNNING_ON_5_10
886 constant so that we can take advantage
887 of some of the nice bits of 5.10
890 - uses the IS_RUNNING_ON_5_10 flag to
891 optimize the &linearized_isa method
892 and avoid the hack/check for circular
893 inheritence in &class_precedence_list
894 - added rebless_instance method (Sartak)
895 - added tests for this
897 * Class::MOP::Immutable
898 - the immutable class now keeps track of
899 the transformer which immutablized it
901 * Class::MOP::Instance
902 - added rebless_instance_structure method (Sartak)
903 - added tests for this
905 0.50 Fri. Dec. 21, 2007

918 0.49 Fri. Dec. 14, 2007
919 !! Class::MOP now loads 2 x faster !!
920 !! with XS speedups (thanks konobi) !!
923 - removed the dependency on B
924 - added two XS functions (thanks konobi)
925 - get_code_info($code) which replaces all
926 the B fiddling we were doing with
927 faster/leaner XS level fiddling
928 - check_package_cache_flag($pkg_name) which
929 returns the PL_sub_generation variable to
930 be used to help manage method caching.
933 In 5.10 or greater this will actually
934 use the mro::get_pkg_gen instead to give
935 even more accurate caching information.
936 blblack++ for that stuff :)
939 - added the &subclasses method (thanks rlb)
940 - added the update_package_cache_flag and
941 reset_package_cache_flag which help keep
942 track of when we need to re-fetch the
944 - Several small improvements to take advantage
945 of the new method map caching features
947 0.48 Mon. Nov. 26, 2007
948 * Class::MOP::Attribute
949 - fixed get_read/write_method to handle the

962 pruning duplicate classes (this will be even more
963 useful in the 5.10-compat version coming soon)
965 * Class::MOP::Attribute
966 - added the get_read_method_ref and get_write_method_ref
967 methods which allow you to retrieve a CODE ref which
968 can always be used to read or write an attribute.
970 0.45 Thurs. Nov. 13, 2007
971 * Class::MOP::Attribute
972 - Fix error message on confess (groditi)
974 0.44 Thurs. Nov. 13, 2007

998 - removed the relevant attributes
1000 * Class::MOP::Method::Constructor
1001 - fixed the cached values we had to be more sane
1002 - made this a subclass of Class::MOP::Method::Generated
1003 - fixed generated constructor so it properly handles
1005 - added tests for this
1006 - added the option to allow for both inlined and
1007 non-inlined constructors.
1008 - Update inlined methods for builder and predicate changes (groditi)
1010 * Class::MOP::Method::Generated
1011 - added this class as an abstract base for the
1012 Class::MOP::Method::{Constructor,Accessor} classes
1013 - added tests for this

1026 - alter symbol table handling to deal with 5.8.x and 5.9.x
1029 - Get rid of the crappy workaround from 0.40/41
1031 0.41 Sun. July 15, 2007
1033 Arghh!!! My TODO test didn't work, so I handle
1034 it manually now so that people can use this
1035 with 5.9.5/bleadperl without issue.
1037 0.40 Tues, July 3, 2007
1039 ~ marked a test in 003_methods.t as TODO
1040 for perl 5.9.5 (this test is irrelvant to
1041 the module functioning on 5.9.5 for the most
1044 0.39 Mon. June 18, 2007
1045 * Class::MOP::Immutable
1046 - added make_metaclass_mutable + docs (groditi)
1047 - removed unused variable
1048 - added create_immutable_transformer
1049 necessary for sane overloading of immutable behavior
1050 - tests for this (groditi)
1053 - Immutability can now be undone,
1054 added make_mutable + tests + docs (groditi)
1055 - Massive changes to the way Immutable is done
1056 for details see comments next to make_immutable
1057 This fixes a bug where custom metaclasses broke
1058 when made immutable. We are now keeping one immutable
1059 metaclass instance per metaclass instead of just one
1060 to prevent isa hierarchy corruption. Memory use will go
1061 up, but I suspect it will be neglible.
1062 - New tests added for this behavior. (groditi)
1064 0.38 Thurs. May 31, 2007
1065 ~~ More documentation updates ~~
1067 * Class::MOP::Package
1068 - we now deal with stub methods properly

1073 - added get_read_method and get_write_method
1074 thanks to groditi for this code, tests
1076 - added tests and POD for this
1079 - fixed RT issue #27329, clone object now
1080 handles undef values correctly.
1081 - added tests for this
1082 - Corrected anon-class handling so that they
1083 will not get reaped when instances still
1084 exist which need to reference them. This is
1085 the correct behavior, hopefully this is an
1086 obscure enough feature that there are not too
1087 many work arounds out in the wild.
1088 - added tests for this by groditi
1089 - updated docs to explain this
1092 - load custom metaclasses automatically (thanks groditi)
1093 - added tests for this behavior
1095 0.37 Sat. March 10, 2007

1102 * Class::MOP::Attribute
1103 - default now checks the instance with defined to
1104 avoid setting off bool-overloads (found by Carl Franks)
1108 - bad name in a test, causing meaningless failuress.
1113 ~~ GLOBAL CHANGES ~~
1114 - All attribute names are now consistent and follow Perl 6
1115 style (prefixed with the sigil, and ! as the twigil for
1116 private attrs). This should not affect any code, unless
1117 you broke encapsulation, in which case, it is your problem
1120 !! Class::MOP::Class::Immutable has been removed
1122 * Class::MOP::Method::Constructor
1123 - this has been moved out of Class::MOP::Class::Immutable
1124 and is a proper subclass of Class::MOP::Method now.
1127 - this module now uses Class::MOP::Immutable for the
1128 immutable transformation instead of
1129 Class::MOP::Class::Immutable.
1131 + Class::MOP::Immutable
1132 - this module now controls the transformation from a mutable
1133 to an immutable version of the class. Docs for this will
1134 be coming eventually.
1137 0.36 Sun. Nov. 5, 2006
1139 - added a few 'no warnings' lines to keep annoying
1140 (and meaningless) warnings from chirping during
1144 - some more bootstrapping is now done on the new
1147 * Class::MOP::Class::Immutable
1149 - constructor generation is now handled by
1150 the Class::MOP::Method::Constructor class
1152 * Class::MOP::Method::Constructor
1153 - created this to handle constructor generation
1154 in Class::MOP::Class::Immutable
1156 * Class::MOP::Attribute
1158 - attributes now delegate to the
1159 Class::MOP::Method::Accessor to generate
1162 * Class::MOP::Method::Accessor
1163 - all accessor generation functions from
1164 Class::MOP::Attribute have been moved here

1169 - initial prototype of a class browser, more
1170 on this to come. Comments and patches are

1175 re-generated in the bootstrap, instead
1176 they are aliased from the originals

1180 - adjusted tests for this
1181 - added the Class::MOP::Instance attributes

1188 - adjusted tests to compensate
1189 - adjusted docs for this
1192 - changed how methods are dealt with to
1193 encapsulate most of the work into the
1194 &get_method_map method
1195 - made several adjustments for the change
1196 in Class::MOP::Method
1197 - &add_attribute now checks if you are adding
1198 a duplicate name, and properly removes the
1199 old one before installing the new one
1200 - added tests for this
1201 - adjusted docs for this
1203 * Class::MOP::Class::Immutable
1204 - added caching of &get_method_map
1205 - fixed issue with &get_package_symbol
1206 - cleaned up the methods that die (patch by David Wheeler)

1210 &list_all_package_symbols
1212 0.34 Sat. Aug. 26, 2006
1214 - added the %:methods attribute, which like
1215 the $:version and such just actually goes
1216 to the symbol table to get it's stuff.
1217 However, it makes the MOP more complete.
1219 - The &create method now requires that all
1220 but the package name now is passed in as
1221 named parameters. See docs for more info.
1222 - updated docs and tests for this
1224 * Class::MOP::Object
1225 - added &dump method to easily Data::Dumper

1247 are no longer allowed for defaults
1248 - added tests for this
1250 * Class::MOP::Package
1251 - fixed an issue with perl 5.8.1 and how it deals
1252 with symbol tables. The namespace hash is now
1253 always reloaded from the symbol table.
1255 ~ lots of misc. documentation cleanup
1257 0.32 Sat. Aug. 12, 2006
1258 + added Class::MOP::Object so that the
1259 metamodel is more complete (and closer
1260 to what Perl 6 will probably be).

1264 the primary gateway between the metaclass
1265 and the Perl 5 symbol table
1266 - added many tests for this
1267 - this class is now a subclass of
1269 - added some tests to reflect this

1273 use Class::MOP::Package methods instead
1275 * Class::MOP::Module
1276 - adding the $:version attribute in the bootstrap
1277 so that Module has a version as an attribute
1278 - see comment in Class::MOP for details
1279 - added the $:authority attribute to this module
1280 as well as an &identifier method, to bring us
1281 ever closer to Perl 6 goodness
1282 - I have added $AUTHORITY to all the modules
1283 - added tests for this

1302 - added &set_value and &get_value for getting
1303 the value of the attribute for a particular
1306 0.30 Wed. July 5, 2006
1307 ---------------------------------------
1308 This is the first version of Class::MOP
1309 to introduce the immutable features which
1310 will be used for optimizating the MOP.
1311 This support should still be considered
1312 experimental, but moving towards stability.
1313 ---------------------------------------
1315 * Created Class::MOP::Class::Immutable
1317 * Created the Class::MOP::Package and
1318 Class::MOP::Module classes to more
1319 closely conform to Perl 6's meta-model
1322 - now inherits from Class::MOP::Module
1323 - several methods moved to ::Module and
1324 ::Package and now inherited
1325 - added tests for this
1327 * Class::MOP::Instance
1328 - added an is_inlinable method to allow other
1329 classes to check before they attempt to optimize.
1330 - added an inline_create_instance to inline
1331 instance creation (of course)
1334 - the Class::MOP::Class::*_package_variable
1335 methods are all now methods of Class::MOP::Package
1336 and called *_package_symbol instead. This is
1337 because they are now more general purpose symbol
1338 table manipulation methods.
1340 0.29_02 Thurs. June 22, 2006
1341 ++ DEVELOPER RELEASE ++
1343 - small change in &create so that it behaves

1399 - attribute slot initialization is now the responsibility
1400 of the attribute itself, and construct_instance now
1401 delegates appropriately
1403 * Class::MOP::Attribute

1405 of the attribute itself, so we added a method for it
1406 called initialize_instance_slot

1435 0.21 Wed. March 15, 2006
1437 - fixed issue where metaclasses are reaped from

1464 - &add_around_method_modifier
1465 - added tests and docs for these
1466 - added &find_next_method_by_name which finds the

1469 0.12 Thurs. Feb 23, 2006
1470 - reduced the dependency on B, no need to always
1474 - added docs to the C3 method dispatch order test
1475 - fixed missing Algorithm::C3 dependency by making

1487 0.10 Tues Feb. 14, 2006
1488 ** This release was mostly about writing more tests and
1489 cleaning out old and dusty code, the MOP should now
1490 be considered "ready to use".
1492 - adding more tests to get coverage up a little higher,
1493 mostly testing errors and edge cases.
1494 - test coverage is now at 99%
1497 - no longer optionally exports to UNIVERSAL::meta or
1498 creates a custom metaclass generator, use the
1499 metaclass pragma instead.
1502 - fixed a number of minor issues which came up in the
1503 error/edge-case tests
1505 * Class::MOP::Attribute
1506 - fixed a number of minor issues which came up in the
1507 error/edge-case tests
1510 - fixing the AttributesWithHistory example, it was broken.
1512 0.06 Thurs Feb. 9, 2006
1514 - adding new metaclass pragma to make setting up the
1515 metaclass a little more straightforward
1518 - clean up bootstrapping to include more complete
1519 attribute definitions for Class::MOP::Class and
1520 Class::MOP::Attribute (accessors, readers, writers,
1521 etc.) ... it is redundant, but is useful meta-info
1525 - fixing minor meta-circularity issue with &meta, it
1526 is now more useful for subclasses
1527 - added &get_attribute_map as an accessor for the
1528 hash of attribute meta objects
1529 - &compute_all_applicable_attributes now just returns
1530 the attribute meta-object, rather than the HASH ref
1531 since all the same info can be gotten from the
1532 attribute meta-object itself
1533 - updated docs & tests to reflect
1534 - added &clone_instance method which does a deep clone
1535 of the instance structure created by &construct_instance
1536 - added docs & tests for this
1537 - added Clone as a dependency
1538 - added &new_object and &clone_object convience methods to
1539 return blessed new or cloned instances
1540 - they handle Class::MOP::Class singletons correctly too
1541 - added docs & tests for this
1542 - cleaned up the &constuct_class_instance so that it behaves
1543 more like &construct_instance (and managed the singletons too)
1544 - added the &check_metaclass_compatibility method to make sure
1545 that metaclasses are upward and downward compatible.
1546 - added tests and docs for this
1549 - adjusting code to use the &Class::MOP::Class::meta
1551 - adjusting code to use the metaclass pragma
1553 0.05 Sat Feb. 4, 2006
1555 - added the &attribute_metaclass and &method_metaclass
1556 attributes which contain a metaclass name to use for
1557 attributes/methods respectively
1560 - bootstrap additional attributes for Class::MOP::Class
1563 - adjusted the example code and tests to use the new
1564 &attribute_metaclass feature of Class::MOP::Class
1565 - added new example:
1568 0.04 Fri Feb. 3, 2006
1570 - some documentation suggestions from #perl6
1572 * Class::MOP::Attribute
1573 - improved error messages

1585 - attributes are now associated with class directly
1588 - refactored the InsideOut example to take advantage
1589 of the Class::MOP::Attribute refactoring
1590 - changed example files to .pod files and hide thier
1591 package names from PAUSE (I don't want to own these
1592 namespaces really, they are just examples)
1594 0.02 Thurs Feb. 2, 2006
1595 - moving examples from t/lib/* to examples/*
1596 - adding POD documentation to the examples
