1 Revision history for Perl extension Class-MOP.
5 - The load_class function just returns true, since it's return value was
6 confusing (either a metaclass object or a class name). It either loads
7 a class or dies trying. In the future, this may change to not return
8 anything, since there's no point in checking its return
9 value. Addresses RT #45883. (Dave Rolsky)
11 * Class::MOP::Class::Trait::Immutable
12 - When throwing an error because of an immutable method, include that
13 method's name. Addresses RT #49680. (Shawn M Moore)
16 - Adding the same sub reference to multiple packages failed to update
17 the method map properly. RT #48985. Reported by Paul Mooney. (Dave
19 - The get_method_map method is now private (and called as
20 _full_method_map or _method_map). The public version is available as a
21 deprecated method. (Dave Rolsky)
23 0.92_01 Thu, Sep 10, 2009
25 - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
28 - Make sure XS code handles magical scalars correctly. (Goro Fuji)
31 - Documented the immutable_options method, which is useful if you need
32 to make a class mutable temporarily, and then nede to restore
33 immutability. (Dave Rolsky)
36 - Deprecated features have been moved to their own module,
37 Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)
42 - Move get_method_map and its various scaffolding into Package. (hdp)
45 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
46 the first argument, rather than just a coderef. (doy)
48 * Class::MOP::Attribute
50 - Allow attribute names to be false (while still requiring them to be
54 * Class::MOP::Method::Wrapped
55 - Fixing variable usage issues with the patch from previous
56 version, not properly using lexicals in the for
60 Japan Perl Association has sponsored Goro Fuji to improve startup
61 performance of Class::MOP and Moose. These enhancements may break
62 backwards compatibility if you're doing (or using) complex
63 metaprogramming, so, as always, test your code!
64 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
68 - Anonymous classes were not completely destroyed when they went
69 out of scope, leading to a memory leak. RT #47480. (Goro
73 - The get_method, has_method, and add_method methods no longer
74 use get_method_map. Method objects are instantiated
75 lazily. This significantly improves Class::MOP's load
79 - Inline fewer metaclass-level constructors since the ones we
80 have are perfectly fine. This reduces the number of string
83 * Class::MOP::Method::Wrapped
84 - If a method modifier set $_, this caused the modifier to blow
85 up, because of some weird internals. (Jeremy Stashewsky)
89 * Class::MOP::Class::Immutable::Trait
90 - Made the Trait act like a role with a bunch of "around"
91 modifiers, rather than sticking it in the inheritance
92 hierarchy. This fixes various problems that caused with
93 metaclass compatibility, which broke Fey::ORM.
96 - Allow a blessed code reference as the method body. Fixes a
97 problem interaction with MooseX::Types. (ash)
99 * Class::MOP::Instance
100 - add inline version of rebless_instance_structure. (doy)
101 - change inline_slot_access to use single quotes (gphat)
103 0.88 Tue, Jun 23, 2009
105 - Moved the __INSTANCE__ parameter to _construct_instance from
107 - Fixed some issues involving metaclasses of metaclasses and
110 0.87 Sun, Jun 21, 2009
112 - Made sure to always local-ize $@ and $SIG{__DIE__} before
113 calling an eval. Fixes RT #45973.
116 - Synced docs about immutability with the current reality (which
117 changed back in 0.82_01)
118 - Removed the immutable_transformer method, which had been
119 returning undef since 0.82_01 anyway.
122 - Got rid of tests which needed Moose and improved testing of
123 constructor/destructor inlining warnings. Fixes RT #47119.
125 0.86 Tue, Jun 16, 2009
127 - If you redefined a subroutine at runtime and then wrapped it
128 with a method modifier, the modifier could in some cases wrap
129 the original version of the subroutine. Fixes RT #46957.
132 - make_immutable issues a warning instead of overriding an
133 existing DESTROY method (Dylan William Hardison). Fixes RT
136 0.85 Sat, Jun 6, 2009
137 * Class::MOP::Attribute
138 - Allow default values to be Class::MOP::Methods. (Florian
140 - Test the above. (Rhesa Rozendaal)
141 - Tweak original commit so the intent matches the accepted
142 behavior (Nicholas Perez)
145 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
148 - Add direct_subclasses method (Sartak)
149 - Tests for subclasses and direct_subclasses (Sartak)
150 - subname is no longer used unconditionally in add_method, but
151 only if the code reference's name is '__ANON__' (nothingmuch)
152 - Add a hook for _superclasses_updated (Sartak)
155 - Remove long, old warning about possibly outdated modules
158 0.84 Tue, May 12, 2009
160 - Depend on Text::Exception 0.27 to avoid failing tests ond old
164 - Made is_class_loaded a little stricter. It was reporting that
165 a class was loaded if it merely had an @ISA variable in its
166 stash. Now it checks that the @ISA var has elements in it.
167 - Deprecate in_global_destruction and subname re-exporting
171 - Explicitly use Devel::GlobalDestruction and Sub::Name
174 * Class::MOP::Package
175 - Disable prototype mismatch warnings for add_package_symbol.
178 - Add test for finding methods from $meta->name->meta before immutable,
181 0.83 Mon, April 27, 2009
183 - Fix segfault when calling get_method_map on a metaclass for an empty
186 0.82_02 Fri, April 24, 2009
187 * Class::MOP::Method::Inlined
188 - Don't inline if the expected method is not defined at all (happens with
189 e.g. Moose::Object::_new is the expected method due to an overridden
192 - Some tests were trying to load Class::MOP::Immutable, which
193 was removed in 0.82_01.
195 0.82_01 Thu, April 23, 2009
196 * Class::MOP::Immutable (and others)
197 - Refactor the immutability system to use a pre-defined class
198 for the immutable metaclass of Class::MOP::Class::Immutable::$class
199 - Rather than generating methods into this class every time, use
200 a Trait (basic mixin) to supply the cached methods
201 - Remove the hack that returns the mutable metaclass for
202 metacircularity in order to provide consistent meta-metaclasses
203 for the Moose compatibility handling code
204 (mst broke it, nothingmuch fixed it)
206 0.82 Mon, April 20, 2009
208 - The deprecation wrappers for some renamed methods were not
209 passing arguments to the new method. (nothingmuch)
211 * Class::MOP::Immutable
212 - Warn during immutablization if the local class provides its own
213 constructor, to parallel the warning in Moose when a superclass
214 provides its own constructor (doy)
216 0.81 Tue, April 7, 2009
219 * Class::MOP::Instance
220 * Class::MOP::Attribute
221 * Class::MOP::Method::Accessor
222 * Class::MOP::Method::Constructor
223 - Include stack traces in the deprecation warnings introduced in
224 0.80_01. (Florian Ragwitz)
227 - Avoid c compiler warnings by declaring some unused function
228 arguments. (Florian Ragwitz)
230 0.80_01 Sun, April 5, 2009
232 - Make sure to preserve any compiler flags already defined in
233 Config.pm. Patch by Vincent Pit. RT #44739.
235 * Many methods have been renamed with a leading underscore, and a
236 few have been deprecated entirely. The methods with a leading
237 underscore are consider "internals only". People writing
238 subclasses or extensions to Class::MOP should feel free to
239 override them, but they are not for "public" use.
242 - construct_class_instance => _construct_class_instance (use new_object)
243 - construct_instance => _construct_instance (use new_object)
244 - check_metaclass_compatibility => _check_metaclass_compatibility
245 - create_meta_instance => _create_meta_instance (use get_meta_instance)
246 - clone_instance => _clone_instance (use clone_object)
247 - compute_all_applicable_methods is deprecated, use get_all_methods
248 - compute_all_applicable_attributes is deprecated, use get_all_attributes
250 - Class::MOP::Instance
251 - bless_instance_structure is deprecated and will be removed
255 - create has been renamed to _instantiate_module. This method
256 does not construct an object, it evals some code that
257 creates the relevant package in Perl's symbol table.
259 - Class::MOP::Method::Accessor
260 - initialize_body => _initialize_body (this is always called
261 when an object is constructed)
262 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
264 - Class::MOP::Method::Constructor
265 - initialize_body => _initialize_body (this is always called
266 when an object is constructed)
267 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
268 - attributes => _attributes
269 - meta_instance => _meta_instance
271 0.80 Wed, April 1, 2009
273 - Call user_class->meta in fewer places, with the eventual goal
274 of allowing the user to rename or exclude ->meta
275 altogether. Instead uses Class::MOP::class_of. (Sartak)
278 - New class_of function that should be used to retrieve a
279 metaclass. This is unlike get_metaclass_by_name in that it
280 accepts instances, not just class names. (Sartak)
283 - load_first_existing_class didn't actually load the first
284 existing class; instead, it loaded the first existing and
285 compiling class. It now throws an error if a class exists (in
286 @INC) but fails to compile. (hdp)
290 - we had some semi-buggy code that purported to provide a
291 HAS_ISAREV based on whether mro had get_isarev (due to an
292 oversight, it always returned 1). Since mro and MRO::Compat
293 have always had get_isarev, HAS_ISAREV was pointless. This
294 insight simplified the subclasses method by deleting the
295 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
297 0.79 Fri, March 29, 2009
298 * No changes from 0.78_02.
300 0.78_02 Thu, March 26, 2009
302 * Class::MOP::Immutable
303 - A big backwards-incompatible refactoring of the Immutable API,
304 and the make_immutable/make_mutable pieces of the Class
305 API. The core __PACKAGE__->meta->make_immutable API remains
306 the same, however, so this should only affect the most
310 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
311 has been fixed to be backwards compatible with 5.8.x.
314 - Add a hook for rebless_instance_away (Sartak)
315 - Use blessed instead of ref to get an instance's class name
316 in rebless_instance. (Sartak)
318 0.78_01 Wed, March 18, 2009
320 - Revised and reorganized all of the API documentation. All
321 classes now have (more or less) complete API documentation.
324 * Class::MOP::Instance
325 - Reblessing into a package that supports overloading wasn't
326 properly adding overload magic to the object due to a bug
327 in (at least) 5.8.8. We now use $_[1] directly which seems
328 to set the magic properly. (Sartak)
330 * Class::MOP::Attribute
331 - The process_accessors method is now private. A public alias
332 exists (and will stick around for a few releases), but it
333 warns that calling the public method is deprecated.
335 * Class::MOP::Method::Generated
336 - Removed the new and _new methods, since this is an abstract
337 base class, and all existing subclasses implement their own
341 - Stop is_class_loaded from thinking a class is loaded if it
342 only has an empty GV (Florian Ragwitz).
343 - Add a test for this (Yappo).
344 - Refactor get_all_package_symbols to allow short-circuiting
346 - Use this in is_class_loaded (Florian Ragwitz).
347 - Stop segfaulting when trying to get the name from a sub that's
348 still being compiled (Florian Ragwitz).
349 - Add tests for this (Florian Ragwitz).
350 - Prefix all public symbols with "mop_" (Florian Ragwitz).
351 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
352 - Simplify creating simple xs reader methods (Florian Ragwitz).
353 - Make everything compile with c++ compilers (Florian Ragwitz).
354 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
357 - Remove optional test plans for tests depending on Sub::Name as
358 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
361 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
363 0.78 Mon, February 23, 2009
364 * No changes from 0.77_01
366 0.77_01 Sun, February 22, 2009
368 - This package now requires its XS components. Not using
369 Sub::Name lead to different behavior and bugginess in the pure
370 Perl version of the code. A Moose test would fail when run
371 against the pure Perl version of this code.
373 * Class::MOP::Instance
374 - The inline_* methods now quote attribute names themselves, and
375 don't expect to receive a quoted value.
378 0.77 Sat, February 14, 2009
380 - Avoid assertion errors on debugging perls in is_class_loaded
384 - Fixed various corner cases where is_class_loaded incorrectly
385 returned true for a class that wasn't really loaded. (Dave
389 - Add get_all_method_names (Sartak)
390 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
392 * Class::MOP::Package
393 - Disable deprecated get_all_package_symbols in list
394 context. (Florian Ragwitz)
397 - Make sure we generate a BSD-compatible Makefile (Florian
401 - The misspelled "check_metaclass_compatability" method we've
402 kept around for backwards compat_i_bility will be removed in a
403 near future release. You've been warned.
405 0.76 Thu, January 22, 2009
406 * Class::MOP::Method::Generated
407 - Added new private methods to support code generation, which
408 are being used by Moose and can be used by MooseX
410 - Generated methods are now generated with a #line directive
411 reflecting the source of the generated method. (nothingmuch)
414 - Clarified documentation of methods that return
415 Class::MOP::Method objects. (doy)
418 - Clarified documentation of the metaclass cache methods. (Sartak)
421 - Add test showing how the xs Class::MOP::is_class_loaded can
422 be made to operate differently to the pure perl version (t0m)
424 0.75 Wed, December 31, 2008
426 - A class that was made immutable and then mutable could end up
427 sharing an immutable transformer object
428 (Class::MOP::Immutable) with other classes, leading to all
429 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
431 0.74 Tue, December 25, 2008
433 - Add an xs implementation of Class::MOP::is_class_loaded (closes
434 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
435 - Changed internals to make prehashing of hash keys easier and less
436 error-prone. (Florian Ragwitz)
438 - Fix documentation to show that around modifiers happen on both
439 sides of the modified method. (Dave Rolsky)
441 0.73 Tue, December 16, 2008
443 - Don't use Perl_mro_meta_init. It's not part of the public perl
444 api. Fixes failures to build on Win32 (RT #41750). (Florian
446 * t/082_get_code_info.t
447 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
448 munger anonymous subs when under -d and so making the tests
449 succeed in that case.
451 0.72 Mon, December 8, 2008
452 * Class::MOP::Package
453 - Pass options to _new, so subclass' attributes can be
456 - In the docs, indicate that package_name and name are required
457 when calling ->wrap (Stefan O'Rear)
459 0.71_02 Fri, December 5, 2008
460 * Class::MOP::Immutable
461 - Added a new attribute, inlined_constructor, which is true if
462 the constructor was inlined.
463 * Class::MOP::Package
464 - Make get_all_package_symbols return a hash ref in scalar
465 context and deprecate calling it in list context with a
466 warning. (Florian Ragwitz)
468 - Various improvements and refactoring, making things more robust and
469 easier to maintain. (Florian Ragwitz)
471 0.71_01 Wed, December 3, 2008
473 - Add an "execute" method to invoke the body so
474 we can avoid using the coderef overload (Sartak)
475 * Class::MOP::Immutable
476 - When we memoize methods, get their results lazily
477 to remove some compile-time cost (Sartak)
478 - Small speedup from eliminating several method
481 - Some small internal tweaks to try to reduce the number of
482 times we call get_method_map when bootstrapping the MOP. This
483 might make loading Class::MOP (and Moose) a little
484 faster. (Dave Rolsky)
485 - Implemented an optional XS version of get_method_map. Mostly
486 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
487 help form Florian Ragwitz. (Dave Rolsky)
488 - Make the behaviour of of get_all_package_symbols (and
489 therefore get_method_map) consistent for stub methods. Report
490 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
492 0.71 Wed November 26, 2008
495 - Actual package creation has moved upward from
496 Class to Module so that Moose roles can share
499 0.70_01 Mon, November 19, 2008
501 - Fixes for failures with blead (Florian Ragwitz)
502 - Silenced compiler warnings (Florian Ragwitz)
504 0.70 Fri, November 14, 2008
506 - Fixed an odd corner case where the XS version of
507 get_all_package_symbols could cause a segfault. This only
508 happened with inlined constants in Perl 5.10.0 (Florian
511 0.69 Fri, November 7, 2008
512 * Class::MOP::Method::Wrapped
513 - Added introspection methods for method modifiers (Dave Rolsky)
516 0.68 Fri October 24, 2008
518 - Make load_class require by file name instead of module name.
519 This stops confusing error messages when loading '__PACKAGE__'.
521 - Add load_one_class_of function to enable you to load one of a
522 list of classes, rather than having to call load_class multiple
523 times in an eval. (t0m)
525 0.67 Tue October 14, 2008
527 - Call a method on the class after setting the superclass list
528 so that we can get Perl to detect cycles before MRO::Compat
529 spirals into an infinite loop (sartak)
530 - Reported by Schwern, [rt.cpan.org #39001]
531 - In create(), pass unused options on to initialize()
532 - added test for this
534 0.66 Sat September 20, 2008
535 !! This release has an incompatible change regarding !!
536 introspection of a class's method with Class::MOP::Class !!
539 - We (us maintainers) now run all tests with XS and then without
540 XS, which should help us catch skew between the XS/pure Perl
544 ! The alias_method method has been deprecated. It now simply
545 calls add_method instead. There is no distinction between
546 aliased methods and "real" methods.
548 This means that methods added via alias_method now show up as
549 part of the class's method list/map. This is a backwards
550 incompatible change, but seems unlikely to break any
551 code. Famous last words. (Dave Rolsky)
554 - Fixed the spelling of "compatibility", but we still have a
555 "check_metaclass_compatability" method for backwards
558 0.65 Mon September 1, 2008
559 For those not following the series of dev releases, the changes
560 from 0.64 from 0.65 can mostly be summed up as a lot performance
561 improvements by nothingmuch, including new optional XS versions of
562 some methods. Also, Class::MOP now works _without_ any XS modules,
563 for sad systems without a compiler.
566 - Added name and package_name XS accessors, and make sure all
567 the XS and Perl versions work the same way. (Dave Rolsky)
570 - The XS versions of various methods just returned undef when
571 called class methods, rather than dying like the pure Perl
572 versions. (Dave Rolsky)
574 0.64_07 Fri August 29, 2008
576 - Silenced warnings that managed to break Moose tests when XS
577 was loaded. (Dave Rolsky)
578 - Some XS versions of methods were ignored because of typos in
579 MOP.xs. (Dave Rolsky)
581 0.64_06 Mon August 25, 2008
582 * Class::MOP (MOP.xs)
583 - Another MS VC++ fix, cannot declare a variable in the middle
584 of a scope (Taro Nishino).
586 0.64_05 Sun August 24, 2008
588 - None of the dev releases actually loaded the XS properly, but
589 we silently fell back to the pure Perl version of the
592 * Class::MOP (MOP.xs)
593 - Replaced some code that used functions not available on Visual
594 C++ with some Perl XS API bits (Dave Rolsky).
596 0.64_04 Sat August 23, 2008
598 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
600 * pod.t and pod_coveraget.t
601 - These are no longer shipped with the tarball because of bogus
602 failures from CPAN testers. (Dave Rolsky)
604 0.64_03 Thu August 21, 2008
605 * Class::MOP::Package
606 - Some (legit) code was misparsed by earlier 5.8.x
607 releases. (nothingmuch)
610 - Fix a constant in void context warning (nothingmuch)
612 0.64_02 Thu August 21, 2008
613 * Makefile.PL and Class::MOP
614 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
617 - Add missing prereqs that got lost in the switch away from
620 * Class::MOP::Instance
621 - New method - get_all_attributes (nothingmuch)
623 0.64_01 Wed August 20, 2008
625 - We now check to see if you have a compiler. If you don't, the
626 module installs without some XS bits, but will work the same
627 as with XS. This should make it easier to install on platforms
628 without a compiler (like Windows). (Dave Rolsky)
631 - Perl 6 style attribute naming replaced with sane style ('methods', not
632 '%!methods'). These changes should not impact any existing API uses.
636 - Quite a number of optimizations based on profiling, including
637 allowing constructors to take hash references instead of
638 hashes, duplicating some frequently used code in XS, and
639 making constructors immutable. These changes should not impact
640 any existing API uses. (nothingmuch)
643 - Constructors now respect the meta attributes of their subclasses,
644 facilitating MOP extensibility. More related changes will happen in the
645 next several releases. (nothingmuch)
648 - New method - get_all_methods, replaces the deprecated
649 compute_all_applicable_methods. get_all_attributes provided for
650 consistency (nothingmuch)
651 - New method - wrap_method was refactored out of get_method_map
653 - New API for meta instance invalidation - invalidate_meta_instance,
654 invalidate_meta_instances, add_dependent_meta_instance,
655 remove_dependent_meta_instance, called automatically when attribute
656 definitions change and allows notification of dependent subclasses.
659 0.64 Sun August 3, 2008
660 * Class::MOP::Immutable
661 - fixing subtle edge case in immutable when you
663 - clean up option processing (nothingmuch)
665 * Class::MOP::Instance
666 - inlined initialize slot didn't match
667 non-inlined (nothingmuch)
669 0.63 Mon July 7, 2008
671 - load_class will initialize a metaclass even if
672 the class is already loaded (sartak)
673 - load_class now returns the metaclass instance
674 instead of just 1 (sartak)
677 - better error messages (sartak and Dave Rolsky)
679 0.62 Wed June 18, 2008
680 - in is_class_loaded, recognize scalar references (as opposed to globs) in
681 the symbol table as methods (these are optimized constant subs)
683 0.61 Fri. June 13, 2008
684 - Okay, lets give this another try and see if PAUSE
685 recognizes it correct this time.
687 0.60 Thurs. Jun 12, 2008
688 - Fixed a version number issue by bumping all modules
691 0.59 Thurs. Jun 12, 2008
692 !! Several fixes resulting in yet another 25-30% speedup !!
695 - now stores the instance of the instance
696 metaclass to avoid needless recomputation
697 and deletes it when the cache is blown
698 - introduce methods to query Class::MOP::Class for
699 the options used to make it immutable as well as
700 the proper immutable transformer. (groditi)
702 * Class::MOP::Package
703 - {add, has, get, remove}_package_symbol all
704 now accept a HASH ref argument as well as the
705 string. All internal usages now use the HASH
709 - MOP.xs does sanity checks on the coderef
711 - is_class_loaded check now uses code that
712 was improved in Moose's ClassName type
714 - nonsensical (undef, empty, reference) class
715 names now throw a more direct error in
717 - tests for this and other aspects of
723 Class::MOP::Method::Wrapped
724 Class::MOP::Attribute
725 - switched usage of reftype to ref because
728 0.58 Thurs. May 29, 2008
729 (late night release engineering)--
731 - fixing the version is META.yml, no functional
732 changes in this release
734 0.57 Wed. May 28, 2008
735 !! Several speedups resulting in 20-25% speedups !!
736 || (thanks to konobi, groditi, mst & CataMoose) !!
739 - made get_method_map use list_all_package_symbols
740 instead of manually grabbing each symbol
741 - streamlining &initialize somewhat, since it gets
744 * Class::MOP::Package
745 - made {get, has}_package_symbol not call
747 - inlining a few calls to &name with
748 direct HASH access key access
749 - added get_all_package_symbols to fetch
750 a HASH of items based on a type filter
751 similar to list_all_package_symbols
752 - added tests for this
755 Class::MOP::Method::Constructor
756 Class::MOP::Method::Generated
757 Class::MOP::Method::Accessor
758 - added more descriptive error message to help
759 keep people from wasting time tracking an error
760 that is easily fixed by upgrading.
762 * Class::MOP::Immutable
763 - Don't inline a destructor unless the user actually
765 - added tests for this
767 0.56 Saturday, May 24, 2008
769 - we now get the &check_package_cache_flag
770 function from MRO::Compat
771 - All XS based functionality now has a
772 Pure Perl alternative
773 - the CLASS_MOP_NO_XS environment variable
774 can now be used to force non-XS versions

780 anon-sub ref in the method metaclass when
782 - added tests for this
784 * Class::MOP::Immutable
785 - added the ability to "wrap" methods when
786 making the class immutable
789 - now handling the edge case of ->meta->identifier
790 dying by wrapping add_package_symbol to specifically
791 allow for it to work.
792 - added tests for this
794 * Class::MOP::Attribute
796 Class::MOP::Immutable
797 - any time a method meta object is constructed
798 we make sure to pass the correct package and
799 method name information
802 Class::MOP::Method::Wrapped
803 Class::MOP::Method::Generated
804 Class::MOP::Method::Accessor
805 Class::MOP::Method::Consructor
806 - the &wrap constructor method now requires that a
807 'package_name' and 'name' attribute are passed. This
808 is to help support the no-XS version, and will
809 throw an error if these are not supplied.
810 - all these classes are now bootstrapped properly
811 and now store the package_name and name attributes
814 ~ Build.PL has been removed since the
815 Module::Install support has been removed
817 0.55 Mon. April 28, 2008
818 - All classes now have proper C3 MRO support
819 - added MRO::Compat as a dependency to allow
820 for the C3 MRO support to Just Work in all
824 - rebless_instance now returns the instance
825 it has just blessed, this is mostly to
827 - set the attr correctly in rebless_instance
828 when it has no init_arg
829 - tweaked &linear_isa and &class_precedence_list
830 to support c3 classes.
832 0.54 Fri. March, 14, 2008
835 - making sure that load_class never gets
836 passed a value from @_ or $_ to squash
837 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
840 - make_{immutable,mutable} now return 1
842 - improved error handling in ->create method
843 - rebless_instance now takes extra params which
844 will be used to populate values
845 - added tests for this
848 - localizing the Data::Dumper configurations so
849 that it does not pollute others (RT #33509)
855 Class::MOP::Attribute
856 - these classes no longer define their own ->meta,
857 but instead just inherit from Class::MOP::Object
859 * Class::MOP::Instance
860 Class::MOP::Immutable
861 - these classes now inherit from Class::MOP::Object
864 - fixed the filename length on several
865 test files so we install on VMS better
867 - fixed incorrect use of catdir when it
868 should be catfile (RT #32385)

877 to indicate that no constructor args can
878 be passed (thanks to nothingmuch)
879 - added tests for this
880 - added attribute initializer attribute (rjbs)
883 - making this use the new init_arg => undef
884 feature instead of the silly hack from
885 before (thanks to nothingmuch)
887 0.52 Tues. Jan. 22, 2008
889 - fixed bug in rebless_instance
892 * Class::MOP::Method::Constructor
893 - removed assumptions about the existence of
896 0.51 Mon. Jan. 14, 2008
897 ~~~ some misc. doc. fixes ~~~
898 ~~ updated copyright dates ~~
901 - now sets the IS_RUNNING_ON_5_10
902 constant so that we can take advantage
903 of some of the nice bits of 5.10
906 - uses the IS_RUNNING_ON_5_10 flag to
907 optimize the &linearized_isa method
908 and avoid the hack/check for circular
909 inheritence in &class_precedence_list
910 - added rebless_instance method (Sartak)
911 - added tests for this
913 * Class::MOP::Immutable
914 - the immutable class now keeps track of
915 the transformer which immutablized it
917 * Class::MOP::Instance
918 - added rebless_instance_structure method (Sartak)
919 - added tests for this
921 0.50 Fri. Dec. 21, 2007

934 0.49 Fri. Dec. 14, 2007
935 !! Class::MOP now loads 2 x faster !!
936 !! with XS speedups (thanks konobi) !!
939 - removed the dependency on B
940 - added two XS functions (thanks konobi)
941 - get_code_info($code) which replaces all
942 the B fiddling we were doing with
943 faster/leaner XS level fiddling
944 - check_package_cache_flag($pkg_name) which
945 returns the PL_sub_generation variable to
946 be used to help manage method caching.
949 In 5.10 or greater this will actually
950 use the mro::get_pkg_gen instead to give
951 even more accurate caching information.
952 blblack++ for that stuff :)
955 - added the &subclasses method (thanks rlb)
956 - added the update_package_cache_flag and
957 reset_package_cache_flag which help keep
958 track of when we need to re-fetch the
960 - Several small improvements to take advantage
961 of the new method map caching features
963 0.48 Mon. Nov. 26, 2007
964 * Class::MOP::Attribute
965 - fixed get_read/write_method to handle the
966 HASH ref case, which makes the

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

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

1001 call through (groditi)
1003 * Class::MOP::Attribute

1014 - removed the relevant attributes
1016 * Class::MOP::Method::Constructor
1017 - fixed the cached values we had to be more sane
1018 - made this a subclass of Class::MOP::Method::Generated
1019 - fixed generated constructor so it properly handles
1021 - added tests for this
1022 - added the option to allow for both inlined and
1023 non-inlined constructors.
1024 - Update inlined methods for builder and predicate changes (groditi)
1026 * Class::MOP::Method::Generated
1027 - added this class as an abstract base for the
1028 Class::MOP::Method::{Constructor,Accessor} classes
1029 - added tests for this

1042 - alter symbol table handling to deal with 5.8.x and 5.9.x
1045 - Get rid of the crappy workaround from 0.40/41
1047 0.41 Sun. July 15, 2007
1049 Arghh!!! My TODO test didn't work, so I handle
1050 it manually now so that people can use this
1051 with 5.9.5/bleadperl without issue.
1053 0.40 Tues, July 3, 2007
1055 ~ marked a test in 003_methods.t as TODO
1056 for perl 5.9.5 (this test is irrelvant to
1057 the module functioning on 5.9.5 for the most
1060 0.39 Mon. June 18, 2007
1061 * Class::MOP::Immutable
1062 - added make_metaclass_mutable + docs (groditi)
1063 - removed unused variable
1064 - added create_immutable_transformer
1065 necessary for sane overloading of immutable behavior
1066 - tests for this (groditi)
1069 - Immutability can now be undone,
1070 added make_mutable + tests + docs (groditi)
1071 - Massive changes to the way Immutable is done
1072 for details see comments next to make_immutable
1073 This fixes a bug where custom metaclasses broke
1074 when made immutable. We are now keeping one immutable
1075 metaclass instance per metaclass instead of just one
1076 to prevent isa hierarchy corruption. Memory use will go
1077 up, but I suspect it will be neglible.
1078 - New tests added for this behavior. (groditi)
1080 0.38 Thurs. May 31, 2007
1081 ~~ More documentation updates ~~
1083 * Class::MOP::Package
1084 - we now deal with stub methods properly

1088 * Class::MOP::Attribute
1089 - added get_read_method and get_write_method
1090 thanks to groditi for this code, tests
1092 - added tests and POD for this
1095 - fixed RT issue #27329, clone object now
1096 handles undef values correctly.
1097 - added tests for this
1098 - Corrected anon-class handling so that they
1099 will not get reaped when instances still
1100 exist which need to reference them. This is
1101 the correct behavior, hopefully this is an
1102 obscure enough feature that there are not too
1103 many work arounds out in the wild.
1104 - added tests for this by groditi
1105 - updated docs to explain this
1108 - load custom metaclasses automatically (thanks groditi)
1109 - added tests for this behavior
1111 0.37 Sat. March 10, 2007

1120 avoid setting off bool-overloads (found by Carl Franks)
1124 - bad name in a test, causing meaningless failuress.
1129 ~~ GLOBAL CHANGES ~~
1130 - All attribute names are now consistent and follow Perl 6
1131 style (prefixed with the sigil, and ! as the twigil for
1132 private attrs). This should not affect any code, unless
1133 you broke encapsulation, in which case, it is your problem
1136 !! Class::MOP::Class::Immutable has been removed
1138 * Class::MOP::Method::Constructor
1139 - this has been moved out of Class::MOP::Class::Immutable
1140 and is a proper subclass of Class::MOP::Method now.
1143 - this module now uses Class::MOP::Immutable for the
1144 immutable transformation instead of
1145 Class::MOP::Class::Immutable.
1147 + Class::MOP::Immutable
1148 - this module now controls the transformation from a mutable
1149 to an immutable version of the class. Docs for this will
1150 be coming eventually.
1153 0.36 Sun. Nov. 5, 2006
1155 - added a few 'no warnings' lines to keep annoying
1156 (and meaningless) warnings from chirping during
1160 - some more bootstrapping is now done on the new
1163 * Class::MOP::Class::Immutable
1165 - constructor generation is now handled by
1166 the Class::MOP::Method::Constructor class
1168 * Class::MOP::Method::Constructor
1169 - created this to handle constructor generation
1170 in Class::MOP::Class::Immutable
1172 * Class::MOP::Attribute
1174 - attributes now delegate to the
1175 Class::MOP::Method::Accessor to generate
1178 * Class::MOP::Method::Accessor
1179 - all accessor generation functions from
1180 Class::MOP::Attribute have been moved here
1182 0.35 Sat. Sept. 30, 2006
1184 * scripts/class_browser.pl
1185 - initial prototype of a class browser, more
1186 on this to come. Comments and patches are
1190 - All Class::MOP::* accessors are no longer
1191 re-generated in the bootstrap, instead
1192 they are aliased from the originals
1193 - fixed tests to reflect
1194 - added Class::MOP::Method (and its subclasses)
1196 - adjusted tests for this
1197 - added the Class::MOP::Instance attributes

1204 - adjusted tests to compensate
1205 - adjusted docs for this
1208 - changed how methods are dealt with to
1209 encapsulate most of the work into the
1210 &get_method_map method
1211 - made several adjustments for the change
1212 in Class::MOP::Method
1213 - &add_attribute now checks if you are adding
1214 a duplicate name, and properly removes the
1215 old one before installing the new one
1216 - added tests for this
1217 - adjusted docs for this
1219 * Class::MOP::Class::Immutable
1220 - added caching of &get_method_map
1221 - fixed issue with &get_package_symbol
1222 - cleaned up the methods that die (patch by David Wheeler)

1226 &list_all_package_symbols
1228 0.34 Sat. Aug. 26, 2006
1230 - added the %:methods attribute, which like
1231 the $:version and such just actually goes
1232 to the symbol table to get it's stuff.
1233 However, it makes the MOP more complete.
1235 - The &create method now requires that all
1236 but the package name now is passed in as
1237 named parameters. See docs for more info.
1238 - updated docs and tests for this
1240 * Class::MOP::Object
1241 - added &dump method to easily Data::Dumper

1262 - reference values (other than CODE refs)
1263 are no longer allowed for defaults
1264 - added tests for this
1266 * Class::MOP::Package
1267 - fixed an issue with perl 5.8.1 and how it deals
1268 with symbol tables. The namespace hash is now
1269 always reloaded from the symbol table.
1271 ~ lots of misc. documentation cleanup
1273 0.32 Sat. Aug. 12, 2006
1274 + added Class::MOP::Object so that the
1275 metamodel is more complete (and closer
1276 to what Perl 6 will probably be).

1280 the primary gateway between the metaclass
1281 and the Perl 5 symbol table
1282 - added many tests for this

1289 use Class::MOP::Package methods instead
1291 * Class::MOP::Module
1292 - adding the $:version attribute in the bootstrap
1293 so that Module has a version as an attribute
1294 - see comment in Class::MOP for details
1295 - added the $:authority attribute to this module
1296 as well as an &identifier method, to bring us
1297 ever closer to Perl 6 goodness
1298 - I have added $AUTHORITY to all the modules
1299 - added tests for this

1315 anywhere within the class hierarchy
1317 * Class::MOP::Attribute
1318 - added &set_value and &get_value for getting
1319 the value of the attribute for a particular
1322 0.30 Wed. July 5, 2006
1323 ---------------------------------------
1324 This is the first version of Class::MOP
1325 to introduce the immutable features which
1326 will be used for optimizating the MOP.
1327 This support should still be considered
1328 experimental, but moving towards stability.
1329 ---------------------------------------
1331 * Created Class::MOP::Class::Immutable
1333 * Created the Class::MOP::Package and
1334 Class::MOP::Module classes to more
1335 closely conform to Perl 6's meta-model
1338 - now inherits from Class::MOP::Module
1339 - several methods moved to ::Module and
1340 ::Package and now inherited
1341 - added tests for this
1343 * Class::MOP::Instance
1344 - added an is_inlinable method to allow other
1345 classes to check before they attempt to optimize.
1346 - added an inline_create_instance to inline
1347 instance creation (of course)
1350 - the Class::MOP::Class::*_package_variable
1351 methods are all now methods of Class::MOP::Package
1352 and called *_package_symbol instead. This is
1353 because they are now more general purpose symbol
1354 table manipulation methods.
1356 0.29_02 Thurs. June 22, 2006
1357 ++ DEVELOPER RELEASE ++
1359 - small change in &create so that it behaves

1364 ++ DEVELOPER RELEASE ++
1365 - This release works in combination with
1366 Moose 0.09_01, it is a developer release

1411 - added tests for this
1412 - added get_all_metaclasses, get_all_metaclass_names
1413 and get_all_metaclass_instances method to allow
1414 access to all the cached metaclass objects.
1415 - attribute slot initialization is now the responsibility
1416 of the attribute itself, and construct_instance now
1417 delegates appropriately
1419 * Class::MOP::Attribute
1420 - attribute slot initialization is now the responsibility
1421 of the attribute itself, so we added a method for it
1422 called initialize_instance_slot

1426 initialize_instance_slot method
1428 0.24 Tues. April 11, 2006

1435 - fixed the way attribute defaults are handled
1436 during instance construction (bug found by chansen)
1438 * Class::MOP::Attribute
1439 - read-only accessors ('reader') will now die if
1440 passed more than one argument (attempting to write

1449 - added test case for this
1451 0.21 Wed. March 15, 2006
1453 - fixed issue where metaclasses are reaped from
1454 our cache in global destruction, and so are not
1455 available in DESTORY calls
1457 0.20 Thurs. March 2, 2006
1458 - removed the dependency for Clone since
1459 we no longer to deep-cloning by default.
1461 * Class::MOP::Method
1462 - added &package_name, &name and
1463 &fully_qualified_name methods, some of
1464 which were formerly private subs in
1467 * Class::MOP::Method::Wrapped
1468 - allows for a method to be wrapped with
1469 before, after and around modifiers
1470 - added tests and docs for this feature
1473 - improved &get_package_symbol
1474 - &version and &superclasses now use it
1475 - methods are now blessed into Class::MOP::Method
1477 - added methods to install CLOS-style method modifiers
1478 - &add_before_method_modifier
1479 - &add_after_method_modifier
1480 - &add_around_method_modifier
1481 - added tests and docs for these
1482 - added &find_next_method_by_name which finds the
1483 equivalent of SUPER::method_name
1485 0.12 Thurs. Feb 23, 2006
1486 - reduced the dependency on B, no need to always
1490 - added docs to the C3 method dispatch order test
1491 - fixed missing Algorithm::C3 dependency by making
1492 the test skip if it is not installed
1494 0.11 Mon Feb. 20, 2006
1496 - added example of changing method dispatch order to C3
1499 - changed how clone_instance behaves, it now only does a
1500 shallow clone (see docs for more details)
1501 - added docs and tests
1503 0.10 Tues Feb. 14, 2006
1504 ** This release was mostly about writing more tests and
1505 cleaning out old and dusty code, the MOP should now
1506 be considered "ready to use".
1508 - adding more tests to get coverage up a little higher,
1509 mostly testing errors and edge cases.
1510 - test coverage is now at 99%
1513 - no longer optionally exports to UNIVERSAL::meta or
1514 creates a custom metaclass generator, use the
1515 metaclass pragma instead.
1518 - fixed a number of minor issues which came up in the
1519 error/edge-case tests
1521 * Class::MOP::Attribute
1522 - fixed a number of minor issues which came up in the
1523 error/edge-case tests
1526 - fixing the AttributesWithHistory example, it was broken.
1528 0.06 Thurs Feb. 9, 2006
1530 - adding new metaclass pragma to make setting up the
1531 metaclass a little more straightforward
1534 - clean up bootstrapping to include more complete
1535 attribute definitions for Class::MOP::Class and
1536 Class::MOP::Attribute (accessors, readers, writers,
1537 etc.) ... it is redundant, but is useful meta-info
1541 - fixing minor meta-circularity issue with &meta, it
1542 is now more useful for subclasses
1543 - added &get_attribute_map as an accessor for the
1544 hash of attribute meta objects
1545 - &compute_all_applicable_attributes now just returns
1546 the attribute meta-object, rather than the HASH ref
1547 since all the same info can be gotten from the
1548 attribute meta-object itself
1549 - updated docs & tests to reflect
1550 - added &clone_instance method which does a deep clone
1551 of the instance structure created by &construct_instance
1552 - added docs & tests for this
1553 - added Clone as a dependency
1554 - added &new_object and &clone_object convience methods to
1555 return blessed new or cloned instances
1556 - they handle Class::MOP::Class singletons correctly too
1557 - added docs & tests for this
1558 - cleaned up the &constuct_class_instance so that it behaves
1559 more like &construct_instance (and managed the singletons too)
1560 - added the &check_metaclass_compatibility method to make sure
1561 that metaclasses are upward and downward compatible.
1562 - added tests and docs for this
1565 - adjusting code to use the &Class::MOP::Class::meta
1567 - adjusting code to use the metaclass pragma
1569 0.05 Sat Feb. 4, 2006
1571 - added the &attribute_metaclass and &method_metaclass
1572 attributes which contain a metaclass name to use for
1573 attributes/methods respectively
1576 - bootstrap additional attributes for Class::MOP::Class
1579 - adjusted the example code and tests to use the new
1580 &attribute_metaclass feature of Class::MOP::Class
1581 - added new example:
1584 0.04 Fri Feb. 3, 2006
1586 - some documentation suggestions from #perl6
1588 * Class::MOP::Attribute
1589 - improved error messages

1604 - refactored the InsideOut example to take advantage
1605 of the Class::MOP::Attribute refactoring
1606 - changed example files to .pod files and hide thier
1607 package names from PAUSE (I don't want to own these
1608 namespaces really, they are just examples)
1610 0.02 Thurs Feb. 2, 2006
1611 - moving examples from t/lib/* to examples/*
1612 - adding POD documentation to the examples
