1 Revision history for Perl extension Class-MOP.
5 - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
8 - Make sure XS code handles magical scalars correctly. (Goro Fuji)
11 - Documented the immutable_options method, which is useful if you need
12 to make a class mutable temporarily, and then nede to restore
13 immutability. (Dave Rolsky)
16 - Deprecated features have been moved to their own module,
17 Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)
22 - Move get_method_map and its various scaffolding into Package. (hdp)
25 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
26 the first argument, rather than just a coderef. (doy)
28 * Class::MOP::Attribute
30 - Allow attribute names to be false (while still requiring them to be
34 * Class::MOP::Method::Wrapped
35 - Fixing variable usage issues with the patch from previous
36 version, not properly using lexicals in the for
40 Japan Perl Association has sponsored Goro Fuji to improve startup
41 performance of Class::MOP and Moose. These enhancements may break
42 backwards compatibility if you're doing (or using) complex
43 metaprogramming, so, as always, test your code!
44 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
48 - Anonymous classes were not completely destroyed when they went
49 out of scope, leading to a memory leak. RT #47480. (Goro
53 - The get_method, has_method, and add_method methods no longer
54 use get_method_map. Method objects are instantiated
55 lazily. This significantly improves Class::MOP's load
59 - Inline fewer metaclass-level constructors since the ones we
60 have are perfectly fine. This reduces the number of string
63 * Class::MOP::Method::Wrapped
64 - If a method modifier set $_, this caused the modifier to blow
65 up, because of some weird internals. (Jeremy Stashewsky)
69 * Class::MOP::Class::Immutable::Trait
70 - Made the Trait act like a role with a bunch of "around"
71 modifiers, rather than sticking it in the inheritance
72 hierarchy. This fixes various problems that caused with
73 metaclass compatibility, which broke Fey::ORM.
76 - Allow a blessed code reference as the method body. Fixes a
77 problem interaction with MooseX::Types. (ash)
79 * Class::MOP::Instance
80 - add inline version of rebless_instance_structure. (doy)
81 - change inline_slot_access to use single quotes (gphat)
83 0.88 Tue, Jun 23, 2009
85 - Moved the __INSTANCE__ parameter to _construct_instance from
87 - Fixed some issues involving metaclasses of metaclasses and
90 0.87 Sun, Jun 21, 2009
92 - Made sure to always local-ize $@ and $SIG{__DIE__} before
93 calling an eval. Fixes RT #45973.
96 - Synced docs about immutability with the current reality (which
97 changed back in 0.82_01)
98 - Removed the immutable_transformer method, which had been
99 returning undef since 0.82_01 anyway.
102 - Got rid of tests which needed Moose and improved testing of
103 constructor/destructor inlining warnings. Fixes RT #47119.
105 0.86 Tue, Jun 16, 2009
107 - If you redefined a subroutine at runtime and then wrapped it
108 with a method modifier, the modifier could in some cases wrap
109 the original version of the subroutine. Fixes RT #46957.
112 - make_immutable issues a warning instead of overriding an
113 existing DESTROY method (Dylan William Hardison). Fixes RT
116 0.85 Sat, Jun 6, 2009
117 * Class::MOP::Attribute
118 - Allow default values to be Class::MOP::Methods. (Florian
120 - Test the above. (Rhesa Rozendaal)
121 - Tweak original commit so the intent matches the accepted
122 behavior (Nicholas Perez)
125 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
128 - Add direct_subclasses method (Sartak)
129 - Tests for subclasses and direct_subclasses (Sartak)
130 - subname is no longer used unconditionally in add_method, but
131 only if the code reference's name is '__ANON__' (nothingmuch)
132 - Add a hook for _superclasses_updated (Sartak)
135 - Remove long, old warning about possibly outdated modules
138 0.84 Tue, May 12, 2009
140 - Depend on Text::Exception 0.27 to avoid failing tests ond old
144 - Made is_class_loaded a little stricter. It was reporting that
145 a class was loaded if it merely had an @ISA variable in its
146 stash. Now it checks that the @ISA var has elements in it.
147 - Deprecate in_global_destruction and subname re-exporting
151 - Explicitly use Devel::GlobalDestruction and Sub::Name
154 * Class::MOP::Package
155 - Disable prototype mismatch warnings for add_package_symbol.
158 - Add test for finding methods from $meta->name->meta before immutable,
161 0.83 Mon, April 27, 2009
163 - Fix segfault when calling get_method_map on a metaclass for an empty
166 0.82_02 Fri, April 24, 2009
167 * Class::MOP::Method::Inlined
168 - Don't inline if the expected method is not defined at all (happens with
169 e.g. Moose::Object::_new is the expected method due to an overridden
172 - Some tests were trying to load Class::MOP::Immutable, which
173 was removed in 0.82_01.
175 0.82_01 Thu, April 23, 2009
176 * Class::MOP::Immutable (and others)
177 - Refactor the immutability system to use a pre-defined class
178 for the immutable metaclass of Class::MOP::Class::Immutable::$class
179 - Rather than generating methods into this class every time, use
180 a Trait (basic mixin) to supply the cached methods
181 - Remove the hack that returns the mutable metaclass for
182 metacircularity in order to provide consistent meta-metaclasses
183 for the Moose compatibility handling code
184 (mst broke it, nothingmuch fixed it)
186 0.82 Mon, April 20, 2009
188 - The deprecation wrappers for some renamed methods were not
189 passing arguments to the new method. (nothingmuch)
191 * Class::MOP::Immutable
192 - Warn during immutablization if the local class provides its own
193 constructor, to parallel the warning in Moose when a superclass
194 provides its own constructor (doy)
196 0.81 Tue, April 7, 2009
199 * Class::MOP::Instance
200 * Class::MOP::Attribute
201 * Class::MOP::Method::Accessor
202 * Class::MOP::Method::Constructor
203 - Include stack traces in the deprecation warnings introduced in
204 0.80_01. (Florian Ragwitz)
207 - Avoid c compiler warnings by declaring some unused function
208 arguments. (Florian Ragwitz)
210 0.80_01 Sun, April 5, 2009
212 - Make sure to preserve any compiler flags already defined in
213 Config.pm. Patch by Vincent Pit. RT #44739.
215 * Many methods have been renamed with a leading underscore, and a
216 few have been deprecated entirely. The methods with a leading
217 underscore are consider "internals only". People writing
218 subclasses or extensions to Class::MOP should feel free to
219 override them, but they are not for "public" use.
222 - construct_class_instance => _construct_class_instance (use new_object)
223 - construct_instance => _construct_instance (use new_object)
224 - check_metaclass_compatibility => _check_metaclass_compatibility
225 - create_meta_instance => _create_meta_instance (use get_meta_instance)
226 - clone_instance => _clone_instance (use clone_object)
227 - compute_all_applicable_methods is deprecated, use get_all_methods
228 - compute_all_applicable_attributes is deprecated, use get_all_attributes
230 - Class::MOP::Instance
231 - bless_instance_structure is deprecated and will be removed
235 - create has been renamed to _instantiate_module. This method
236 does not construct an object, it evals some code that
237 creates the relevant package in Perl's symbol table.
239 - Class::MOP::Method::Accessor
240 - initialize_body => _initialize_body (this is always called
241 when an object is constructed)
242 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
244 - Class::MOP::Method::Constructor
245 - initialize_body => _initialize_body (this is always called
246 when an object is constructed)
247 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
248 - attributes => _attributes
249 - meta_instance => _meta_instance
251 0.80 Wed, April 1, 2009
253 - Call user_class->meta in fewer places, with the eventual goal
254 of allowing the user to rename or exclude ->meta
255 altogether. Instead uses Class::MOP::class_of. (Sartak)
258 - New class_of function that should be used to retrieve a
259 metaclass. This is unlike get_metaclass_by_name in that it
260 accepts instances, not just class names. (Sartak)
263 - load_first_existing_class didn't actually load the first
264 existing class; instead, it loaded the first existing and
265 compiling class. It now throws an error if a class exists (in
266 @INC) but fails to compile. (hdp)
270 - we had some semi-buggy code that purported to provide a
271 HAS_ISAREV based on whether mro had get_isarev (due to an
272 oversight, it always returned 1). Since mro and MRO::Compat
273 have always had get_isarev, HAS_ISAREV was pointless. This
274 insight simplified the subclasses method by deleting the
275 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
277 0.79 Fri, March 29, 2009
278 * No changes from 0.78_02.
280 0.78_02 Thu, March 26, 2009
282 * Class::MOP::Immutable
283 - A big backwards-incompatible refactoring of the Immutable API,
284 and the make_immutable/make_mutable pieces of the Class
285 API. The core __PACKAGE__->meta->make_immutable API remains
286 the same, however, so this should only affect the most
290 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
291 has been fixed to be backwards compatible with 5.8.x.
294 - Add a hook for rebless_instance_away (Sartak)
295 - Use blessed instead of ref to get an instance's class name
296 in rebless_instance. (Sartak)
298 0.78_01 Wed, March 18, 2009
300 - Revised and reorganized all of the API documentation. All
301 classes now have (more or less) complete API documentation.
304 * Class::MOP::Instance
305 - Reblessing into a package that supports overloading wasn't
306 properly adding overload magic to the object due to a bug
307 in (at least) 5.8.8. We now use $_[1] directly which seems
308 to set the magic properly. (Sartak)
310 * Class::MOP::Attribute
311 - The process_accessors method is now private. A public alias
312 exists (and will stick around for a few releases), but it
313 warns that calling the public method is deprecated.
315 * Class::MOP::Method::Generated
316 - Removed the new and _new methods, since this is an abstract
317 base class, and all existing subclasses implement their own
321 - Stop is_class_loaded from thinking a class is loaded if it
322 only has an empty GV (Florian Ragwitz).
323 - Add a test for this (Yappo).
324 - Refactor get_all_package_symbols to allow short-circuiting
326 - Use this in is_class_loaded (Florian Ragwitz).
327 - Stop segfaulting when trying to get the name from a sub that's
328 still being compiled (Florian Ragwitz).
329 - Add tests for this (Florian Ragwitz).
330 - Prefix all public symbols with "mop_" (Florian Ragwitz).
331 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
332 - Simplify creating simple xs reader methods (Florian Ragwitz).
333 - Make everything compile with c++ compilers (Florian Ragwitz).
334 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
337 - Remove optional test plans for tests depending on Sub::Name as
338 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
341 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
343 0.78 Mon, February 23, 2009
344 * No changes from 0.77_01
346 0.77_01 Sun, February 22, 2009
348 - This package now requires its XS components. Not using
349 Sub::Name lead to different behavior and bugginess in the pure
350 Perl version of the code. A Moose test would fail when run
351 against the pure Perl version of this code.
353 * Class::MOP::Instance
354 - The inline_* methods now quote attribute names themselves, and
355 don't expect to receive a quoted value.
358 0.77 Sat, February 14, 2009
360 - Avoid assertion errors on debugging perls in is_class_loaded
364 - Fixed various corner cases where is_class_loaded incorrectly
365 returned true for a class that wasn't really loaded. (Dave
369 - Add get_all_method_names (Sartak)
370 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
372 * Class::MOP::Package
373 - Disable deprecated get_all_package_symbols in list
374 context. (Florian Ragwitz)
377 - Make sure we generate a BSD-compatible Makefile (Florian
381 - The misspelled "check_metaclass_compatability" method we've
382 kept around for backwards compat_i_bility will be removed in a
383 near future release. You've been warned.
385 0.76 Thu, January 22, 2009
386 * Class::MOP::Method::Generated
387 - Added new private methods to support code generation, which
388 are being used by Moose and can be used by MooseX
390 - Generated methods are now generated with a #line directive
391 reflecting the source of the generated method. (nothingmuch)
394 - Clarified documentation of methods that return
395 Class::MOP::Method objects. (doy)
398 - Clarified documentation of the metaclass cache methods. (Sartak)
401 - Add test showing how the xs Class::MOP::is_class_loaded can
402 be made to operate differently to the pure perl version (t0m)
404 0.75 Wed, December 31, 2008
406 - A class that was made immutable and then mutable could end up
407 sharing an immutable transformer object
408 (Class::MOP::Immutable) with other classes, leading to all
409 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
411 0.74 Tue, December 25, 2008
413 - Add an xs implementation of Class::MOP::is_class_loaded (closes
414 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
415 - Changed internals to make prehashing of hash keys easier and less
416 error-prone. (Florian Ragwitz)
418 - Fix documentation to show that around modifiers happen on both
419 sides of the modified method. (Dave Rolsky)
421 0.73 Tue, December 16, 2008
423 - Don't use Perl_mro_meta_init. It's not part of the public perl
424 api. Fixes failures to build on Win32 (RT #41750). (Florian
426 * t/082_get_code_info.t
427 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
428 munger anonymous subs when under -d and so making the tests
429 succeed in that case.
431 0.72 Mon, December 8, 2008
432 * Class::MOP::Package
433 - Pass options to _new, so subclass' attributes can be
436 - In the docs, indicate that package_name and name are required
437 when calling ->wrap (Stefan O'Rear)
439 0.71_02 Fri, December 5, 2008
440 * Class::MOP::Immutable
441 - Added a new attribute, inlined_constructor, which is true if
442 the constructor was inlined.
443 * Class::MOP::Package
444 - Make get_all_package_symbols return a hash ref in scalar
445 context and deprecate calling it in list context with a
446 warning. (Florian Ragwitz)
448 - Various improvements and refactoring, making things more robust and
449 easier to maintain. (Florian Ragwitz)
451 0.71_01 Wed, December 3, 2008
453 - Add an "execute" method to invoke the body so
454 we can avoid using the coderef overload (Sartak)
455 * Class::MOP::Immutable
456 - When we memoize methods, get their results lazily
457 to remove some compile-time cost (Sartak)
458 - Small speedup from eliminating several method
461 - Some small internal tweaks to try to reduce the number of
462 times we call get_method_map when bootstrapping the MOP. This
463 might make loading Class::MOP (and Moose) a little
464 faster. (Dave Rolsky)
465 - Implemented an optional XS version of get_method_map. Mostly
466 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
467 help form Florian Ragwitz. (Dave Rolsky)
468 - Make the behaviour of of get_all_package_symbols (and
469 therefore get_method_map) consistent for stub methods. Report
470 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
472 0.71 Wed November 26, 2008
475 - Actual package creation has moved upward from
476 Class to Module so that Moose roles can share
479 0.70_01 Mon, November 19, 2008
481 - Fixes for failures with blead (Florian Ragwitz)
482 - Silenced compiler warnings (Florian Ragwitz)
484 0.70 Fri, November 14, 2008
486 - Fixed an odd corner case where the XS version of
487 get_all_package_symbols could cause a segfault. This only
488 happened with inlined constants in Perl 5.10.0 (Florian
491 0.69 Fri, November 7, 2008
492 * Class::MOP::Method::Wrapped
493 - Added introspection methods for method modifiers (Dave Rolsky)
496 0.68 Fri October 24, 2008
498 - Make load_class require by file name instead of module name.
499 This stops confusing error messages when loading '__PACKAGE__'.
501 - Add load_one_class_of function to enable you to load one of a
502 list of classes, rather than having to call load_class multiple
503 times in an eval. (t0m)
505 0.67 Tue October 14, 2008
507 - Call a method on the class after setting the superclass list
508 so that we can get Perl to detect cycles before MRO::Compat
509 spirals into an infinite loop (sartak)
510 - Reported by Schwern, [rt.cpan.org #39001]
511 - In create(), pass unused options on to initialize()
512 - added test for this
514 0.66 Sat September 20, 2008
515 !! This release has an incompatible change regarding !!
516 introspection of a class's method with Class::MOP::Class !!
519 - We (us maintainers) now run all tests with XS and then without
520 XS, which should help us catch skew between the XS/pure Perl
524 ! The alias_method method has been deprecated. It now simply
525 calls add_method instead. There is no distinction between
526 aliased methods and "real" methods.
528 This means that methods added via alias_method now show up as
529 part of the class's method list/map. This is a backwards
530 incompatible change, but seems unlikely to break any
531 code. Famous last words. (Dave Rolsky)
534 - Fixed the spelling of "compatibility", but we still have a
535 "check_metaclass_compatability" method for backwards
538 0.65 Mon September 1, 2008
539 For those not following the series of dev releases, the changes
540 from 0.64 from 0.65 can mostly be summed up as a lot performance
541 improvements by nothingmuch, including new optional XS versions of
542 some methods. Also, Class::MOP now works _without_ any XS modules,
543 for sad systems without a compiler.
546 - Added name and package_name XS accessors, and make sure all
547 the XS and Perl versions work the same way. (Dave Rolsky)
550 - The XS versions of various methods just returned undef when
551 called class methods, rather than dying like the pure Perl
552 versions. (Dave Rolsky)
554 0.64_07 Fri August 29, 2008
556 - Silenced warnings that managed to break Moose tests when XS
557 was loaded. (Dave Rolsky)
558 - Some XS versions of methods were ignored because of typos in
559 MOP.xs. (Dave Rolsky)
561 0.64_06 Mon August 25, 2008
562 * Class::MOP (MOP.xs)
563 - Another MS VC++ fix, cannot declare a variable in the middle
564 of a scope (Taro Nishino).
566 0.64_05 Sun August 24, 2008
568 - None of the dev releases actually loaded the XS properly, but
569 we silently fell back to the pure Perl version of the
572 * Class::MOP (MOP.xs)
573 - Replaced some code that used functions not available on Visual
574 C++ with some Perl XS API bits (Dave Rolsky).
576 0.64_04 Sat August 23, 2008
578 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
580 * pod.t and pod_coveraget.t
581 - These are no longer shipped with the tarball because of bogus
582 failures from CPAN testers. (Dave Rolsky)
584 0.64_03 Thu August 21, 2008
585 * Class::MOP::Package
586 - Some (legit) code was misparsed by earlier 5.8.x
587 releases. (nothingmuch)
590 - Fix a constant in void context warning (nothingmuch)
592 0.64_02 Thu August 21, 2008
593 * Makefile.PL and Class::MOP
594 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
597 - Add missing prereqs that got lost in the switch away from
600 * Class::MOP::Instance
601 - New method - get_all_attributes (nothingmuch)
603 0.64_01 Wed August 20, 2008
605 - We now check to see if you have a compiler. If you don't, the
606 module installs without some XS bits, but will work the same
607 as with XS. This should make it easier to install on platforms
608 without a compiler (like Windows). (Dave Rolsky)
611 - Perl 6 style attribute naming replaced with sane style ('methods', not
612 '%!methods'). These changes should not impact any existing API uses.
616 - Quite a number of optimizations based on profiling, including
617 allowing constructors to take hash references instead of
618 hashes, duplicating some frequently used code in XS, and
619 making constructors immutable. These changes should not impact
620 any existing API uses. (nothingmuch)
623 - Constructors now respect the meta attributes of their subclasses,
624 facilitating MOP extensibility. More related changes will happen in the
625 next several releases. (nothingmuch)
628 - New method - get_all_methods, replaces the deprecated
629 compute_all_applicable_methods. get_all_attributes provided for
630 consistency (nothingmuch)
631 - New method - wrap_method was refactored out of get_method_map
633 - New API for meta instance invalidation - invalidate_meta_instance,
634 invalidate_meta_instances, add_dependent_meta_instance,
635 remove_dependent_meta_instance, called automatically when attribute
636 definitions change and allows notification of dependent subclasses.
639 0.64 Sun August 3, 2008
640 * Class::MOP::Immutable
641 - fixing subtle edge case in immutable when you
643 - clean up option processing (nothingmuch)
645 * Class::MOP::Instance
646 - inlined initialize slot didn't match
647 non-inlined (nothingmuch)
649 0.63 Mon July 7, 2008
651 - load_class will initialize a metaclass even if
652 the class is already loaded (sartak)
653 - load_class now returns the metaclass instance
654 instead of just 1 (sartak)
657 - better error messages (sartak and Dave Rolsky)
659 0.62 Wed June 18, 2008
660 - in is_class_loaded, recognize scalar references (as opposed to globs) in
661 the symbol table as methods (these are optimized constant subs)
663 0.61 Fri. June 13, 2008
664 - Okay, lets give this another try and see if PAUSE
665 recognizes it correct this time.
667 0.60 Thurs. Jun 12, 2008
668 - Fixed a version number issue by bumping all modules
671 0.59 Thurs. Jun 12, 2008
672 !! Several fixes resulting in yet another 25-30% speedup !!
675 - now stores the instance of the instance
676 metaclass to avoid needless recomputation
677 and deletes it when the cache is blown
678 - introduce methods to query Class::MOP::Class for
679 the options used to make it immutable as well as
680 the proper immutable transformer. (groditi)
682 * Class::MOP::Package
683 - {add, has, get, remove}_package_symbol all
684 now accept a HASH ref argument as well as the
685 string. All internal usages now use the HASH
689 - MOP.xs does sanity checks on the coderef
691 - is_class_loaded check now uses code that
692 was improved in Moose's ClassName type
694 - nonsensical (undef, empty, reference) class
695 names now throw a more direct error in
697 - tests for this and other aspects of
703 Class::MOP::Method::Wrapped
704 Class::MOP::Attribute
705 - switched usage of reftype to ref because
708 0.58 Thurs. May 29, 2008
709 (late night release engineering)--
711 - fixing the version is META.yml, no functional
712 changes in this release
714 0.57 Wed. May 28, 2008
715 !! Several speedups resulting in 20-25% speedups !!
716 || (thanks to konobi, groditi, mst & CataMoose) !!
719 - made get_method_map use list_all_package_symbols
720 instead of manually grabbing each symbol
721 - streamlining &initialize somewhat, since it gets
724 * Class::MOP::Package
725 - made {get, has}_package_symbol not call
727 - inlining a few calls to &name with
728 direct HASH access key access
729 - added get_all_package_symbols to fetch
730 a HASH of items based on a type filter
731 similar to list_all_package_symbols
732 - added tests for this
735 Class::MOP::Method::Constructor
736 Class::MOP::Method::Generated
737 Class::MOP::Method::Accessor
738 - added more descriptive error message to help
739 keep people from wasting time tracking an error
740 that is easily fixed by upgrading.
742 * Class::MOP::Immutable
743 - Don't inline a destructor unless the user actually
745 - added tests for this
747 0.56 Saturday, May 24, 2008
749 - we now get the &check_package_cache_flag
750 function from MRO::Compat
751 - All XS based functionality now has a
752 Pure Perl alternative
753 - the CLASS_MOP_NO_XS environment variable
754 can now be used to force non-XS versions
757 * Class::MOP::Attribute

760 anon-sub ref in the method metaclass when
762 - added tests for this
764 * Class::MOP::Immutable
765 - added the ability to "wrap" methods when
766 making the class immutable
769 - now handling the edge case of ->meta->identifier
770 dying by wrapping add_package_symbol to specifically
771 allow for it to work.
772 - added tests for this
774 * Class::MOP::Attribute
776 Class::MOP::Immutable
777 - any time a method meta object is constructed
778 we make sure to pass the correct package and
779 method name information
782 Class::MOP::Method::Wrapped
783 Class::MOP::Method::Generated
784 Class::MOP::Method::Accessor
785 Class::MOP::Method::Consructor
786 - the &wrap constructor method now requires that a
787 'package_name' and 'name' attribute are passed. This
788 is to help support the no-XS version, and will
789 throw an error if these are not supplied.
790 - all these classes are now bootstrapped properly
791 and now store the package_name and name attributes
794 ~ Build.PL has been removed since the
795 Module::Install support has been removed
797 0.55 Mon. April 28, 2008
798 - All classes now have proper C3 MRO support
799 - added MRO::Compat as a dependency to allow
800 for the C3 MRO support to Just Work in all
804 - rebless_instance now returns the instance
805 it has just blessed, this is mostly to
807 - set the attr correctly in rebless_instance
808 when it has no init_arg
809 - tweaked &linear_isa and &class_precedence_list
810 to support c3 classes.
812 0.54 Fri. March, 14, 2008
815 - making sure that load_class never gets
816 passed a value from @_ or $_ to squash
817 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
820 - make_{immutable,mutable} now return 1
822 - improved error handling in ->create method
823 - rebless_instance now takes extra params which
824 will be used to populate values
825 - added tests for this
828 - localizing the Data::Dumper configurations so
829 that it does not pollute others (RT #33509)
835 Class::MOP::Attribute
836 - these classes no longer define their own ->meta,
837 but instead just inherit from Class::MOP::Object
839 * Class::MOP::Instance
840 Class::MOP::Immutable
841 - these classes now inherit from Class::MOP::Object
844 - fixed the filename length on several
845 test files so we install on VMS better
847 - fixed incorrect use of catdir when it
848 should be catfile (RT #32385)

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

906 - added tests for this
908 * Class::MOP::Immutable
909 - fixed a bug (see above)
911 * Class::MOP::Attribute
914 0.49 Fri. Dec. 14, 2007
915 !! Class::MOP now loads 2 x faster !!
916 !! with XS speedups (thanks konobi) !!
919 - removed the dependency on B
920 - added two XS functions (thanks konobi)
921 - get_code_info($code) which replaces all
922 the B fiddling we were doing with
923 faster/leaner XS level fiddling
924 - check_package_cache_flag($pkg_name) which
925 returns the PL_sub_generation variable to
926 be used to help manage method caching.
929 In 5.10 or greater this will actually
930 use the mro::get_pkg_gen instead to give
931 even more accurate caching information.
932 blblack++ for that stuff :)
935 - added the &subclasses method (thanks rlb)
936 - added the update_package_cache_flag and
937 reset_package_cache_flag which help keep
938 track of when we need to re-fetch the
940 - Several small improvements to take advantage
941 of the new method map caching features
943 0.48 Mon. Nov. 26, 2007
944 * Class::MOP::Attribute
945 - fixed get_read/write_method to handle the

955 0.46 Fri. Nov. 23, 2007
957 - added the linearized_isa method instead of constantly
958 pruning duplicate classes (this will be even more
959 useful in the 5.10-compat version coming soon)
961 * Class::MOP::Attribute
962 - added the get_read_method_ref and get_write_method_ref
963 methods which allow you to retrieve a CODE ref which
964 can always be used to read or write an attribute.
966 0.45 Thurs. Nov. 13, 2007
967 * Class::MOP::Attribute
968 - Fix error message on confess (groditi)
970 0.44 Thurs. Nov. 13, 2007

996 * Class::MOP::Method::Constructor
997 - fixed the cached values we had to be more sane
998 - made this a subclass of Class::MOP::Method::Generated
999 - fixed generated constructor so it properly handles
1001 - added tests for this
1002 - added the option to allow for both inlined and
1003 non-inlined constructors.
1004 - Update inlined methods for builder and predicate changes (groditi)
1006 * Class::MOP::Method::Generated
1007 - added this class as an abstract base for the
1008 Class::MOP::Method::{Constructor,Accessor} classes
1009 - added tests for this
1012 - Alter tests (005, 014 020, 021) for new builder addition (groditi)

1022 - alter symbol table handling to deal with 5.8.x and 5.9.x
1025 - Get rid of the crappy workaround from 0.40/41
1027 0.41 Sun. July 15, 2007
1029 Arghh!!! My TODO test didn't work, so I handle
1030 it manually now so that people can use this
1031 with 5.9.5/bleadperl without issue.
1033 0.40 Tues, July 3, 2007
1035 ~ marked a test in 003_methods.t as TODO
1036 for perl 5.9.5 (this test is irrelvant to
1037 the module functioning on 5.9.5 for the most
1040 0.39 Mon. June 18, 2007
1041 * Class::MOP::Immutable
1042 - added make_metaclass_mutable + docs (groditi)
1043 - removed unused variable
1044 - added create_immutable_transformer
1045 necessary for sane overloading of immutable behavior
1046 - tests for this (groditi)
1049 - Immutability can now be undone,
1050 added make_mutable + tests + docs (groditi)
1051 - Massive changes to the way Immutable is done
1052 for details see comments next to make_immutable
1053 This fixes a bug where custom metaclasses broke
1054 when made immutable. We are now keeping one immutable
1055 metaclass instance per metaclass instead of just one
1056 to prevent isa hierarchy corruption. Memory use will go
1057 up, but I suspect it will be neglible.
1058 - New tests added for this behavior. (groditi)
1060 0.38 Thurs. May 31, 2007
1061 ~~ More documentation updates ~~
1063 * Class::MOP::Package

1070 thanks to groditi for this code, tests
1072 - added tests and POD for this
1075 - fixed RT issue #27329, clone object now
1076 handles undef values correctly.
1077 - added tests for this
1078 - Corrected anon-class handling so that they
1079 will not get reaped when instances still
1080 exist which need to reference them. This is
1081 the correct behavior, hopefully this is an
1082 obscure enough feature that there are not too
1083 many work arounds out in the wild.
1084 - added tests for this by groditi
1085 - updated docs to explain this
1088 - load custom metaclasses automatically (thanks groditi)
1089 - added tests for this behavior
1091 0.37 Sat. March 10, 2007

1100 avoid setting off bool-overloads (found by Carl Franks)
1104 - bad name in a test, causing meaningless failuress.
1109 ~~ GLOBAL CHANGES ~~
1110 - All attribute names are now consistent and follow Perl 6
1111 style (prefixed with the sigil, and ! as the twigil for
1112 private attrs). This should not affect any code, unless
1113 you broke encapsulation, in which case, it is your problem
1116 !! Class::MOP::Class::Immutable has been removed
1118 * Class::MOP::Method::Constructor
1119 - this has been moved out of Class::MOP::Class::Immutable
1120 and is a proper subclass of Class::MOP::Method now.
1123 - this module now uses Class::MOP::Immutable for the
1124 immutable transformation instead of
1125 Class::MOP::Class::Immutable.
1127 + Class::MOP::Immutable
1128 - this module now controls the transformation from a mutable
1129 to an immutable version of the class. Docs for this will
1130 be coming eventually.
1133 0.36 Sun. Nov. 5, 2006
1135 - added a few 'no warnings' lines to keep annoying
1136 (and meaningless) warnings from chirping during
1140 - some more bootstrapping is now done on the new
1143 * Class::MOP::Class::Immutable
1145 - constructor generation is now handled by
1146 the Class::MOP::Method::Constructor class
1148 * Class::MOP::Method::Constructor
1149 - created this to handle constructor generation
1150 in Class::MOP::Class::Immutable
1152 * Class::MOP::Attribute
1154 - attributes now delegate to the
1155 Class::MOP::Method::Accessor to generate
1158 * Class::MOP::Method::Accessor
1159 - all accessor generation functions from
1160 Class::MOP::Attribute have been moved here

1171 re-generated in the bootstrap, instead
1172 they are aliased from the originals

1176 - adjusted tests for this
1177 - added the Class::MOP::Instance attributes

1184 - adjusted tests to compensate
1185 - adjusted docs for this
1188 - changed how methods are dealt with to
1189 encapsulate most of the work into the
1190 &get_method_map method
1191 - made several adjustments for the change
1192 in Class::MOP::Method
1193 - &add_attribute now checks if you are adding
1194 a duplicate name, and properly removes the
1195 old one before installing the new one
1196 - added tests for this
1197 - adjusted docs for this
1199 * Class::MOP::Class::Immutable
1200 - added caching of &get_method_map
1201 - fixed issue with &get_package_symbol
1202 - cleaned up the methods that die (patch by David Wheeler)

1206 &list_all_package_symbols
1208 0.34 Sat. Aug. 26, 2006
1210 - added the %:methods attribute, which like
1211 the $:version and such just actually goes
1212 to the symbol table to get it's stuff.
1213 However, it makes the MOP more complete.
1215 - The &create method now requires that all
1216 but the package name now is passed in as
1217 named parameters. See docs for more info.
1218 - updated docs and tests for this
1220 * Class::MOP::Object
1221 - added &dump method to easily Data::Dumper

1243 are no longer allowed for defaults
1244 - added tests for this
1246 * Class::MOP::Package
1247 - fixed an issue with perl 5.8.1 and how it deals
1248 with symbol tables. The namespace hash is now
1249 always reloaded from the symbol table.
1251 ~ lots of misc. documentation cleanup
1253 0.32 Sat. Aug. 12, 2006
1254 + added Class::MOP::Object so that the
1255 metamodel is more complete (and closer
1256 to what Perl 6 will probably be).

1260 the primary gateway between the metaclass
1261 and the Perl 5 symbol table
1262 - added many tests for this
1263 - this class is now a subclass of
1265 - added some tests to reflect this

1269 use Class::MOP::Package methods instead
1271 * Class::MOP::Module
1272 - adding the $:version attribute in the bootstrap
1273 so that Module has a version as an attribute
1274 - see comment in Class::MOP for details
1275 - added the $:authority attribute to this module
1276 as well as an &identifier method, to bring us
1277 ever closer to Perl 6 goodness
1278 - I have added $AUTHORITY to all the modules
1279 - added tests for this

1298 - added &set_value and &get_value for getting
1299 the value of the attribute for a particular
1302 0.30 Wed. July 5, 2006
1303 ---------------------------------------
1304 This is the first version of Class::MOP
1305 to introduce the immutable features which
1306 will be used for optimizating the MOP.
1307 This support should still be considered
1308 experimental, but moving towards stability.
1309 ---------------------------------------
1311 * Created Class::MOP::Class::Immutable
1313 * Created the Class::MOP::Package and
1314 Class::MOP::Module classes to more
1315 closely conform to Perl 6's meta-model
1318 - now inherits from Class::MOP::Module
1319 - several methods moved to ::Module and
1320 ::Package and now inherited
1321 - added tests for this
1323 * Class::MOP::Instance
1324 - added an is_inlinable method to allow other
1325 classes to check before they attempt to optimize.
1326 - added an inline_create_instance to inline
1327 instance creation (of course)
1330 - the Class::MOP::Class::*_package_variable
1331 methods are all now methods of Class::MOP::Package
1332 and called *_package_symbol instead. This is
1333 because they are now more general purpose symbol
1334 table manipulation methods.
1336 0.29_02 Thurs. June 22, 2006
1337 ++ DEVELOPER RELEASE ++
1339 - small change in &create so that it behaves

1396 of the attribute itself, and construct_instance now
1397 delegates appropriately
1399 * Class::MOP::Attribute

1401 of the attribute itself, so we added a method for it
1402 called initialize_instance_slot

1406 initialize_instance_slot method
1408 0.24 Tues. April 11, 2006

1431 0.21 Wed. March 15, 2006
1433 - fixed issue where metaclasses are reaped from

1459 - &add_after_method_modifier
1460 - &add_around_method_modifier
1461 - added tests and docs for these
1462 - added &find_next_method_by_name which finds the
1463 equivalent of SUPER::method_name
1465 0.12 Thurs. Feb 23, 2006
1466 - reduced the dependency on B, no need to always
1470 - added docs to the C3 method dispatch order test
1471 - fixed missing Algorithm::C3 dependency by making
1472 the test skip if it is not installed
1474 0.11 Mon Feb. 20, 2006
1476 - added example of changing method dispatch order to C3
1479 - changed how clone_instance behaves, it now only does a
1480 shallow clone (see docs for more details)
1481 - added docs and tests
1483 0.10 Tues Feb. 14, 2006
1484 ** This release was mostly about writing more tests and
1485 cleaning out old and dusty code, the MOP should now
1486 be considered "ready to use".
1488 - adding more tests to get coverage up a little higher,
1489 mostly testing errors and edge cases.
1490 - test coverage is now at 99%
1493 - no longer optionally exports to UNIVERSAL::meta or
1494 creates a custom metaclass generator, use the
1495 metaclass pragma instead.
1498 - fixed a number of minor issues which came up in the
1499 error/edge-case tests
1501 * Class::MOP::Attribute
1502 - fixed a number of minor issues which came up in the
1503 error/edge-case tests
1506 - fixing the AttributesWithHistory example, it was broken.
1508 0.06 Thurs Feb. 9, 2006
1510 - adding new metaclass pragma to make setting up the
1511 metaclass a little more straightforward
1514 - clean up bootstrapping to include more complete
1515 attribute definitions for Class::MOP::Class and
1516 Class::MOP::Attribute (accessors, readers, writers,
1517 etc.) ... it is redundant, but is useful meta-info
1521 - fixing minor meta-circularity issue with &meta, it
1522 is now more useful for subclasses
1523 - added &get_attribute_map as an accessor for the
1524 hash of attribute meta objects
1525 - &compute_all_applicable_attributes now just returns
1526 the attribute meta-object, rather than the HASH ref
1527 since all the same info can be gotten from the
1528 attribute meta-object itself
1529 - updated docs & tests to reflect
1530 - added &clone_instance method which does a deep clone
1531 of the instance structure created by &construct_instance
1532 - added docs & tests for this
1533 - added Clone as a dependency
1534 - added &new_object and &clone_object convience methods to
1535 return blessed new or cloned instances
1536 - they handle Class::MOP::Class singletons correctly too
1537 - added docs & tests for this
1538 - cleaned up the &constuct_class_instance so that it behaves
1539 more like &construct_instance (and managed the singletons too)
1540 - added the &check_metaclass_compatibility method to make sure
1541 that metaclasses are upward and downward compatible.
1542 - added tests and docs for this
1545 - adjusting code to use the &Class::MOP::Class::meta
1547 - adjusting code to use the metaclass pragma
1549 0.05 Sat Feb. 4, 2006
1551 - added the &attribute_metaclass and &method_metaclass
1552 attributes which contain a metaclass name to use for
1553 attributes/methods respectively
1556 - bootstrap additional attributes for Class::MOP::Class
1559 - adjusted the example code and tests to use the new
1560 &attribute_metaclass feature of Class::MOP::Class
1561 - added new example:
1564 0.04 Fri Feb. 3, 2006
1566 - some documentation suggestions from #perl6
1568 * Class::MOP::Attribute
1569 - improved error messages
1572 - added new examples:
1573 - AttributesWithHistory
1574 - ClassEncapsultedAttributes
1576 0.03 Fri Feb. 3, 2006
1577 - converted to Module::Build instead of EU::MM
1579 * Class::MOP::Attribute
1580 - refactored method generation code
1581 - attributes are now associated with class directly
1584 - refactored the InsideOut example to take advantage
1585 of the Class::MOP::Attribute refactoring
1586 - changed example files to .pod files and hide thier
1587 package names from PAUSE (I don't want to own these
1588 namespaces really, they are just examples)
1590 0.02 Thurs Feb. 2, 2006
1591 - moving examples from t/lib/* to examples/*
1592 - adding POD documentation to the examples
