1 Revision history for Perl extension Class-MOP.
4 Japan Perl Association has sponsored Goro Fuji to improve startup
5 performance of Class::MOP and Moose. These enhancements may break
6 backwards compatibility if you're doing (or using) complex
7 metaprogramming, so, as always, test your code!

12 - Anonymous classes were not completely destroyed when they went
13 out of scope, leading to a memory leak. RT #47480. (Goro
17 - The get_method, has_method, and add_method methods no longer
18 use get_method_map. Method objects are instantiated
19 lazily. This significantly improves Class::MOP's load
23 - Inline fewer metaclass-level constructors since the ones we
24 have are perfectly fine. This reduces the number of string
27 * Class::MOP::Method::Wrapped
28 - If a method modifier set $_, this caused the modifier to blow
29 up, because of some weird internals. (Jeremy Stashewsky)
34 * Class::MOP::Class::Immutable::Trait
35 - Made the Trait act like a role with a bunch of "around"
36 modifiers, rather than sticking it in the inheritance
37 hierarchy. This fixes various problems that caused with
38 metaclass compatibility, which broke Fey::ORM.
41 - Allow a blessed code reference as the method body. Fixes a
42 problem interaction with MooseX::Types. (ash)
44 * Class::MOP::Instance
45 - add inline version of rebless_instance_structure. (doy)
46 - change inline_slot_access to use single quotes (gphat)
48 0.88 Tue, Jun 23, 2009
50 - Moved the __INSTANCE__ parameter to _construct_instance from
52 - Fixed some issues involving metaclasses of metaclasses and
55 0.87 Sun, Jun 21, 2009
57 - Made sure to always local-ize $@ and $SIG{__DIE__} before
58 calling an eval. Fixes RT #45973.
61 - Synced docs about immutability with the current reality (which
62 changed back in 0.82_01)
63 - Removed the immutable_transformer method, which had been
64 returning undef since 0.82_01 anyway.
67 - Got rid of tests which needed Moose and improved testing of
68 constructor/destructor inlining warnings. Fixes RT #47119.
70 0.86 Tue, Jun 16, 2009
72 - If you redefined a subroutine at runtime and then wrapped it
73 with a method modifier, the modifier could in some cases wrap
74 the original version of the subroutine. Fixes RT #46957.
77 - make_immutable issues a warning instead of overriding an
78 existing DESTROY method (Dylan William Hardison). Fixes RT
82 * Class::MOP::Attribute
83 - Allow default values to be Class::MOP::Methods. (Florian
85 - Test the above. (Rhesa Rozendaal)
86 - Tweak original commit so the intent matches the accepted
87 behavior (Nicholas Perez)
90 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
93 - Add direct_subclasses method (Sartak)
94 - Tests for subclasses and direct_subclasses (Sartak)
95 - subname is no longer used unconditionally in add_method, but
96 only if the code reference's name is '__ANON__' (nothingmuch)
97 - Add a hook for _superclasses_updated (Sartak)
100 - Remove long, old warning about possibly outdated modules
103 0.84 Tue, May 12, 2009
105 - Depend on Text::Exception 0.27 to avoid failing tests ond old
109 - Made is_class_loaded a little stricter. It was reporting that
110 a class was loaded if it merely had an @ISA variable in its
111 stash. Now it checks that the @ISA var has elements in it.
112 - Deprecate in_global_destruction and subname re-exporting
116 - Explicitly use Devel::GlobalDestruction and Sub::Name
119 * Class::MOP::Package
120 - Disable prototype mismatch warnings for add_package_symbol.
123 - Add test for finding methods from $meta->name->meta before immutable,
126 0.83 Mon, April 27, 2009
128 - Fix segfault when calling get_method_map on a metaclass for an empty
131 0.82_02 Fri, April 24, 2009
132 * Class::MOP::Method::Inlined
133 - Don't inline if the expected method is not defined at all (happens with
134 e.g. Moose::Object::_new is the expected method due to an overridden
137 - Some tests were trying to load Class::MOP::Immutable, which
138 was removed in 0.82_01.
140 0.82_01 Thu, April 23, 2009
141 * Class::MOP::Immutable (and others)
142 - Refactor the immutability system to use a pre-defined class
143 for the immutable metaclass of Class::MOP::Class::Immutable::$class
144 - Rather than generating methods into this class every time, use
145 a Trait (basic mixin) to supply the cached methods
146 - Remove the hack that returns the mutable metaclass for
147 metacircularity in order to provide consistent meta-metaclasses
148 for the Moose compatibility handling code
149 (mst broke it, nothingmuch fixed it)
151 0.82 Mon, April 20, 2009
153 - The deprecation wrappers for some renamed methods were not
154 passing arguments to the new method. (nothingmuch)
156 * Class::MOP::Immutable
157 - Warn during immutablization if the local class provides its own
158 constructor, to parallel the warning in Moose when a superclass
159 provides its own constructor (doy)
161 0.81 Tue, April 7, 2009
164 * Class::MOP::Instance
165 * Class::MOP::Attribute
166 * Class::MOP::Method::Accessor
167 * Class::MOP::Method::Constructor
168 - Include stack traces in the deprecation warnings introduced in
169 0.80_01. (Florian Ragwitz)
172 - Avoid c compiler warnings by declaring some unused function
173 arguments. (Florian Ragwitz)
175 0.80_01 Sun, April 5, 2009
177 - Make sure to preserve any compiler flags already defined in
178 Config.pm. Patch by Vincent Pit. RT #44739.
180 * Many methods have been renamed with a leading underscore, and a
181 few have been deprecated entirely. The methods with a leading
182 underscore are consider "internals only". People writing
183 subclasses or extensions to Class::MOP should feel free to
184 override them, but they are not for "public" use.
187 - construct_class_instance => _construct_class_instance (use new_object)
188 - construct_instance => _construct_instance (use new_object)
189 - check_metaclass_compatibility => _check_metaclass_compatibility
190 - create_meta_instance => _create_meta_instance (use get_meta_instance)
191 - clone_instance => _clone_instance (use clone_object)
192 - compute_all_applicable_methods is deprecated, use get_all_methods
193 - compute_all_applicable_attributes is deprecated, use get_all_attributes
195 - Class::MOP::Instance
196 - bless_instance_structure is deprecated and will be removed
200 - create has been renamed to _instantiate_module. This method
201 does not construct an object, it evals some code that
202 creates the relevant package in Perl's symbol table.
204 - Class::MOP::Method::Accessor
205 - initialize_body => _initialize_body (this is always called
206 when an object is constructed)
207 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
209 - Class::MOP::Method::Constructor
210 - initialize_body => _initialize_body (this is always called
211 when an object is constructed)
212 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
213 - attributes => _attributes
214 - meta_instance => _meta_instance
216 0.80 Wed, April 1, 2009
218 - Call user_class->meta in fewer places, with the eventual goal
219 of allowing the user to rename or exclude ->meta
220 altogether. Instead uses Class::MOP::class_of. (Sartak)
223 - New class_of function that should be used to retrieve a
224 metaclass. This is unlike get_metaclass_by_name in that it
225 accepts instances, not just class names. (Sartak)
228 - load_first_existing_class didn't actually load the first
229 existing class; instead, it loaded the first existing and
230 compiling class. It now throws an error if a class exists (in
231 @INC) but fails to compile. (hdp)
235 - we had some semi-buggy code that purported to provide a
236 HAS_ISAREV based on whether mro had get_isarev (due to an
237 oversight, it always returned 1). Since mro and MRO::Compat
238 have always had get_isarev, HAS_ISAREV was pointless. This
239 insight simplified the subclasses method by deleting the
240 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
242 0.79 Fri, March 29, 2009
243 * No changes from 0.78_02.
245 0.78_02 Thu, March 26, 2009
247 * Class::MOP::Immutable
248 - A big backwards-incompatible refactoring of the Immutable API,
249 and the make_immutable/make_mutable pieces of the Class
250 API. The core __PACKAGE__->meta->make_immutable API remains
251 the same, however, so this should only affect the most
255 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
256 has been fixed to be backwards compatible with 5.8.x.
259 - Add a hook for rebless_instance_away (Sartak)
260 - Use blessed instead of ref to get an instance's class name
261 in rebless_instance. (Sartak)
263 0.78_01 Wed, March 18, 2009
265 - Revised and reorganized all of the API documentation. All
266 classes now have (more or less) complete API documentation.
269 * Class::MOP::Instance
270 - Reblessing into a package that supports overloading wasn't
271 properly adding overload magic to the object due to a bug
272 in (at least) 5.8.8. We now use $_[1] directly which seems
273 to set the magic properly. (Sartak)
275 * Class::MOP::Attribute
276 - The process_accessors method is now private. A public alias
277 exists (and will stick around for a few releases), but it
278 warns that calling the public method is deprecated.
280 * Class::MOP::Method::Generated
281 - Removed the new and _new methods, since this is an abstract
282 base class, and all existing subclasses implement their own
286 - Stop is_class_loaded from thinking a class is loaded if it
287 only has an empty GV (Florian Ragwitz).
288 - Add a test for this (Yappo).
289 - Refactor get_all_package_symbols to allow short-circuiting
291 - Use this in is_class_loaded (Florian Ragwitz).
292 - Stop segfaulting when trying to get the name from a sub that's
293 still being compiled (Florian Ragwitz).
294 - Add tests for this (Florian Ragwitz).
295 - Prefix all public symbols with "mop_" (Florian Ragwitz).
296 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
297 - Simplify creating simple xs reader methods (Florian Ragwitz).
298 - Make everything compile with c++ compilers (Florian Ragwitz).
299 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
302 - Remove optional test plans for tests depending on Sub::Name as
303 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
306 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
308 0.78 Mon, February 23, 2009
309 * No changes from 0.77_01
311 0.77_01 Sun, February 22, 2009
313 - This package now requires its XS components. Not using
314 Sub::Name lead to different behavior and bugginess in the pure
315 Perl version of the code. A Moose test would fail when run
316 against the pure Perl version of this code.
318 * Class::MOP::Instance
319 - The inline_* methods now quote attribute names themselves, and
320 don't expect to receive a quoted value.
323 0.77 Sat, February 14, 2009
325 - Avoid assertion errors on debugging perls in is_class_loaded
329 - Fixed various corner cases where is_class_loaded incorrectly
330 returned true for a class that wasn't really loaded. (Dave
334 - Add get_all_method_names (Sartak)
335 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
337 * Class::MOP::Package
338 - Disable deprecated get_all_package_symbols in list
339 context. (Florian Ragwitz)
342 - Make sure we generate a BSD-compatible Makefile (Florian
346 - The misspelled "check_metaclass_compatability" method we've
347 kept around for backwards compat_i_bility will be removed in a
348 near future release. You've been warned.
350 0.76 Thu, January 22, 2009
351 * Class::MOP::Method::Generated
352 - Added new private methods to support code generation, which
353 are being used by Moose and can be used by MooseX
355 - Generated methods are now generated with a #line directive
356 reflecting the source of the generated method. (nothingmuch)
359 - Clarified documentation of methods that return
360 Class::MOP::Method objects. (doy)
363 - Clarified documentation of the metaclass cache methods. (Sartak)
366 - Add test showing how the xs Class::MOP::is_class_loaded can
367 be made to operate differently to the pure perl version (t0m)
369 0.75 Wed, December 31, 2008
371 - A class that was made immutable and then mutable could end up
372 sharing an immutable transformer object
373 (Class::MOP::Immutable) with other classes, leading to all
374 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
376 0.74 Tue, December 25, 2008
378 - Add an xs implementation of Class::MOP::is_class_loaded (closes
379 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
380 - Changed internals to make prehashing of hash keys easier and less
381 error-prone. (Florian Ragwitz)
383 - Fix documentation to show that around modifiers happen on both
384 sides of the modified method. (Dave Rolsky)
386 0.73 Tue, December 16, 2008
388 - Don't use Perl_mro_meta_init. It's not part of the public perl
389 api. Fixes failures to build on Win32 (RT #41750). (Florian
391 * t/082_get_code_info.t
392 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
393 munger anonymous subs when under -d and so making the tests
394 succeed in that case.
396 0.72 Mon, December 8, 2008
397 * Class::MOP::Package
398 - Pass options to _new, so subclass' attributes can be
401 - In the docs, indicate that package_name and name are required
402 when calling ->wrap (Stefan O'Rear)
404 0.71_02 Fri, December 5, 2008
405 * Class::MOP::Immutable
406 - Added a new attribute, inlined_constructor, which is true if
407 the constructor was inlined.
408 * Class::MOP::Package
409 - Make get_all_package_symbols return a hash ref in scalar
410 context and deprecate calling it in list context with a
411 warning. (Florian Ragwitz)
413 - Various improvements and refactoring, making things more robust and
414 easier to maintain. (Florian Ragwitz)
416 0.71_01 Wed, December 3, 2008
418 - Add an "execute" method to invoke the body so
419 we can avoid using the coderef overload (Sartak)
420 * Class::MOP::Immutable
421 - When we memoize methods, get their results lazily
422 to remove some compile-time cost (Sartak)
423 - Small speedup from eliminating several method
426 - Some small internal tweaks to try to reduce the number of
427 times we call get_method_map when bootstrapping the MOP. This
428 might make loading Class::MOP (and Moose) a little
429 faster. (Dave Rolsky)
430 - Implemented an optional XS version of get_method_map. Mostly
431 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
432 help form Florian Ragwitz. (Dave Rolsky)
433 - Make the behaviour of of get_all_package_symbols (and
434 therefore get_method_map) consistent for stub methods. Report
435 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
437 0.71 Wed November 26, 2008
440 - Actual package creation has moved upward from
441 Class to Module so that Moose roles can share
444 0.70_01 Mon, November 19, 2008
446 - Fixes for failures with blead (Florian Ragwitz)
447 - Silenced compiler warnings (Florian Ragwitz)
449 0.70 Fri, November 14, 2008
451 - Fixed an odd corner case where the XS version of
452 get_all_package_symbols could cause a segfault. This only
453 happened with inlined constants in Perl 5.10.0 (Florian
456 0.69 Fri, November 7, 2008
457 * Class::MOP::Method::Wrapped
458 - Added introspection methods for method modifiers (Dave Rolsky)
461 0.68 Fri October 24, 2008
463 - Make load_class require by file name instead of module name.
464 This stops confusing error messages when loading '__PACKAGE__'.
466 - Add load_one_class_of function to enable you to load one of a
467 list of classes, rather than having to call load_class multiple
468 times in an eval. (t0m)
470 0.67 Tue October 14, 2008
472 - Call a method on the class after setting the superclass list
473 so that we can get Perl to detect cycles before MRO::Compat
474 spirals into an infinite loop (sartak)
475 - Reported by Schwern, [rt.cpan.org #39001]
476 - In create(), pass unused options on to initialize()
477 - added test for this
479 0.66 Sat September 20, 2008
480 !! This release has an incompatible change regarding !!
481 introspection of a class's method with Class::MOP::Class !!
484 - We (us maintainers) now run all tests with XS and then without
485 XS, which should help us catch skew between the XS/pure Perl
489 ! The alias_method method has been deprecated. It now simply
490 calls add_method instead. There is no distinction between
491 aliased methods and "real" methods.
493 This means that methods added via alias_method now show up as
494 part of the class's method list/map. This is a backwards
495 incompatible change, but seems unlikely to break any
496 code. Famous last words. (Dave Rolsky)
499 - Fixed the spelling of "compatibility", but we still have a
500 "check_metaclass_compatability" method for backwards
503 0.65 Mon September 1, 2008
504 For those not following the series of dev releases, the changes
505 from 0.64 from 0.65 can mostly be summed up as a lot performance
506 improvements by nothingmuch, including new optional XS versions of
507 some methods. Also, Class::MOP now works _without_ any XS modules,
508 for sad systems without a compiler.
511 - Added name and package_name XS accessors, and make sure all
512 the XS and Perl versions work the same way. (Dave Rolsky)
515 - The XS versions of various methods just returned undef when
516 called class methods, rather than dying like the pure Perl
517 versions. (Dave Rolsky)
519 0.64_07 Fri August 29, 2008
521 - Silenced warnings that managed to break Moose tests when XS
522 was loaded. (Dave Rolsky)
523 - Some XS versions of methods were ignored because of typos in
524 MOP.xs. (Dave Rolsky)
526 0.64_06 Mon August 25, 2008
527 * Class::MOP (MOP.xs)
528 - Another MS VC++ fix, cannot declare a variable in the middle
529 of a scope (Taro Nishino).
531 0.64_05 Sun August 24, 2008
533 - None of the dev releases actually loaded the XS properly, but
534 we silently fell back to the pure Perl version of the
537 * Class::MOP (MOP.xs)
538 - Replaced some code that used functions not available on Visual
539 C++ with some Perl XS API bits (Dave Rolsky).
541 0.64_04 Sat August 23, 2008
543 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
545 * pod.t and pod_coveraget.t
546 - These are no longer shipped with the tarball because of bogus
547 failures from CPAN testers. (Dave Rolsky)
549 0.64_03 Thu August 21, 2008
550 * Class::MOP::Package
551 - Some (legit) code was misparsed by earlier 5.8.x
552 releases. (nothingmuch)
555 - Fix a constant in void context warning (nothingmuch)
557 0.64_02 Thu August 21, 2008
558 * Makefile.PL and Class::MOP
559 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
562 - Add missing prereqs that got lost in the switch away from
565 * Class::MOP::Instance
566 - New method - get_all_attributes (nothingmuch)
568 0.64_01 Wed August 20, 2008
570 - We now check to see if you have a compiler. If you don't, the
571 module installs without some XS bits, but will work the same
572 as with XS. This should make it easier to install on platforms
573 without a compiler (like Windows). (Dave Rolsky)
576 - Perl 6 style attribute naming replaced with sane style ('methods', not
577 '%!methods'). These changes should not impact any existing API uses.
581 - Quite a number of optimizations based on profiling, including
582 allowing constructors to take hash references instead of
583 hashes, duplicating some frequently used code in XS, and
584 making constructors immutable. These changes should not impact
585 any existing API uses. (nothingmuch)
588 - Constructors now respect the meta attributes of their subclasses,
589 facilitating MOP extensibility. More related changes will happen in the
590 next several releases. (nothingmuch)
593 - New method - get_all_methods, replaces the deprecated
594 compute_all_applicable_methods. get_all_attributes provided for
595 consistency (nothingmuch)
596 - New method - wrap_method was refactored out of get_method_map
598 - New API for meta instance invalidation - invalidate_meta_instance,
599 invalidate_meta_instances, add_dependent_meta_instance,
600 remove_dependent_meta_instance, called automatically when attribute
601 definitions change and allows notification of dependent subclasses.
604 0.64 Sun August 3, 2008
605 * Class::MOP::Immutable
606 - fixing subtle edge case in immutable when you
608 - clean up option processing (nothingmuch)
610 * Class::MOP::Instance
611 - inlined initialize slot didn't match
612 non-inlined (nothingmuch)
614 0.63 Mon July 7, 2008
616 - load_class will initialize a metaclass even if
617 the class is already loaded (sartak)
618 - load_class now returns the metaclass instance
619 instead of just 1 (sartak)
622 - better error messages (sartak and Dave Rolsky)
624 0.62 Wed June 18, 2008
625 - in is_class_loaded, recognize scalar references (as opposed to globs) in
626 the symbol table as methods (these are optimized constant subs)
628 0.61 Fri. June 13, 2008
629 - Okay, lets give this another try and see if PAUSE
630 recognizes it correct this time.
632 0.60 Thurs. Jun 12, 2008
633 - Fixed a version number issue by bumping all modules
636 0.59 Thurs. Jun 12, 2008
637 !! Several fixes resulting in yet another 25-30% speedup !!
640 - now stores the instance of the instance
641 metaclass to avoid needless recomputation
642 and deletes it when the cache is blown
643 - introduce methods to query Class::MOP::Class for
644 the options used to make it immutable as well as
645 the proper immutable transformer. (groditi)
647 * Class::MOP::Package
648 - {add, has, get, remove}_package_symbol all
649 now accept a HASH ref argument as well as the
650 string. All internal usages now use the HASH
654 - MOP.xs does sanity checks on the coderef
656 - is_class_loaded check now uses code that
657 was improved in Moose's ClassName type
659 - nonsensical (undef, empty, reference) class
660 names now throw a more direct error in
662 - tests for this and other aspects of
668 Class::MOP::Method::Wrapped
669 Class::MOP::Attribute
670 - switched usage of reftype to ref because
673 0.58 Thurs. May 29, 2008
674 (late night release engineering)--
676 - fixing the version is META.yml, no functional
677 changes in this release
679 0.57 Wed. May 28, 2008
680 !! Several speedups resulting in 20-25% speedups !!
681 || (thanks to konobi, groditi, mst & CataMoose) !!
684 - made get_method_map use list_all_package_symbols
685 instead of manually grabbing each symbol
686 - streamlining &initialize somewhat, since it gets
689 * Class::MOP::Package
690 - made {get, has}_package_symbol not call
692 - inlining a few calls to &name with
693 direct HASH access key access
694 - added get_all_package_symbols to fetch
695 a HASH of items based on a type filter
696 similar to list_all_package_symbols
697 - added tests for this
700 Class::MOP::Method::Constructor
701 Class::MOP::Method::Generated
702 Class::MOP::Method::Accessor
703 - added more descriptive error message to help
704 keep people from wasting time tracking an error
705 that is easily fixed by upgrading.
707 * Class::MOP::Immutable
708 - Don't inline a destructor unless the user actually
710 - added tests for this
712 0.56 Saturday, May 24, 2008
714 - we now get the &check_package_cache_flag
715 function from MRO::Compat
716 - All XS based functionality now has a
717 Pure Perl alternative
718 - the CLASS_MOP_NO_XS environment variable
719 can now be used to force non-XS versions

730 - added the ability to "wrap" methods when
731 making the class immutable
734 - now handling the edge case of ->meta->identifier
735 dying by wrapping add_package_symbol to specifically
736 allow for it to work.
737 - added tests for this
739 * Class::MOP::Attribute
741 Class::MOP::Immutable
742 - any time a method meta object is constructed
743 we make sure to pass the correct package and
744 method name information
747 Class::MOP::Method::Wrapped
748 Class::MOP::Method::Generated
749 Class::MOP::Method::Accessor
750 Class::MOP::Method::Consructor
751 - the &wrap constructor method now requires that a
752 'package_name' and 'name' attribute are passed. This
753 is to help support the no-XS version, and will
754 throw an error if these are not supplied.
755 - all these classes are now bootstrapped properly
756 and now store the package_name and name attributes
759 ~ Build.PL has been removed since the
760 Module::Install support has been removed
762 0.55 Mon. April 28, 2008
763 - All classes now have proper C3 MRO support
764 - added MRO::Compat as a dependency to allow
765 for the C3 MRO support to Just Work in all
769 - rebless_instance now returns the instance
770 it has just blessed, this is mostly to
772 - set the attr correctly in rebless_instance
773 when it has no init_arg
774 - tweaked &linear_isa and &class_precedence_list
775 to support c3 classes.
777 0.54 Fri. March, 14, 2008
780 - making sure that load_class never gets
781 passed a value from @_ or $_ to squash
782 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
785 - make_{immutable,mutable} now return 1
787 - improved error handling in ->create method
788 - rebless_instance now takes extra params which
789 will be used to populate values
790 - added tests for this
793 - localizing the Data::Dumper configurations so
794 that it does not pollute others (RT #33509)
800 Class::MOP::Attribute
801 - these classes no longer define their own ->meta,
802 but instead just inherit from Class::MOP::Object
804 * Class::MOP::Instance
805 Class::MOP::Immutable
806 - these classes now inherit from Class::MOP::Object
809 - fixed the filename length on several
810 test files so we install on VMS better
812 - fixed incorrect use of catdir when it
813 should be catfile (RT #32385)

816 ~~ several doc. fixes and updates ~~
819 Class::MOP::Method::Constructor
820 Class::MOP::Attribute
821 - making init_arg accept an undefined value
822 to indicate that no constructor args can
823 be passed (thanks to nothingmuch)
824 - added tests for this
825 - added attribute initializer attribute (rjbs)
828 - making this use the new init_arg => undef
829 feature instead of the silly hack from
830 before (thanks to nothingmuch)
832 0.52 Tues. Jan. 22, 2008
834 - fixed bug in rebless_instance
837 * Class::MOP::Method::Constructor
838 - removed assumptions about the existence of
841 0.51 Mon. Jan. 14, 2008
842 ~~~ some misc. doc. fixes ~~~
843 ~~ updated copyright dates ~~
846 - now sets the IS_RUNNING_ON_5_10
847 constant so that we can take advantage
848 of some of the nice bits of 5.10
851 - uses the IS_RUNNING_ON_5_10 flag to
852 optimize the &linearized_isa method
853 and avoid the hack/check for circular
854 inheritence in &class_precedence_list
855 - added rebless_instance method (Sartak)
856 - added tests for this
858 * Class::MOP::Immutable
859 - the immutable class now keeps track of
860 the transformer which immutablized it

880 !! Class::MOP now loads 2 x faster !!
881 !! with XS speedups (thanks konobi) !!
884 - removed the dependency on B
885 - added two XS functions (thanks konobi)
886 - get_code_info($code) which replaces all
887 the B fiddling we were doing with
888 faster/leaner XS level fiddling
889 - check_package_cache_flag($pkg_name) which
890 returns the PL_sub_generation variable to
891 be used to help manage method caching.
894 In 5.10 or greater this will actually
895 use the mro::get_pkg_gen instead to give
896 even more accurate caching information.
897 blblack++ for that stuff :)
900 - added the &subclasses method (thanks rlb)
901 - added the update_package_cache_flag and
902 reset_package_cache_flag which help keep
903 track of when we need to re-fetch the
905 - Several small improvements to take advantage
906 of the new method map caching features
908 0.48 Mon. Nov. 26, 2007
909 * Class::MOP::Attribute
910 - fixed get_read/write_method to handle the

923 pruning duplicate classes (this will be even more
924 useful in the 5.10-compat version coming soon)
926 * Class::MOP::Attribute
927 - added the get_read_method_ref and get_write_method_ref
928 methods which allow you to retrieve a CODE ref which
929 can always be used to read or write an attribute.
931 0.45 Thurs. Nov. 13, 2007
932 * Class::MOP::Attribute
933 - Fix error message on confess (groditi)
935 0.44 Thurs. Nov. 13, 2007

938 0.43 Thurs. Nov. 13, 2007
940 - Add support for the 'builder' attribute (groditi)
943 - optimise metaclass-already-exists check in

954 - Make predicates check for the existence of a value, not whether
955 it is defined (groditi)

958 - made this a subclass of Class::MOP::Method::Generated
959 - removed the relevant attributes
961 * Class::MOP::Method::Constructor
962 - fixed the cached values we had to be more sane
963 - made this a subclass of Class::MOP::Method::Generated
964 - fixed generated constructor so it properly handles
966 - added tests for this
967 - added the option to allow for both inlined and
968 non-inlined constructors.
969 - Update inlined methods for builder and predicate changes (groditi)
971 * Class::MOP::Method::Generated
972 - added this class as an abstract base for the
973 Class::MOP::Method::{Constructor,Accessor} classes
974 - added tests for this

990 - Get rid of the crappy workaround from 0.40/41
992 0.41 Sun. July 15, 2007
994 Arghh!!! My TODO test didn't work, so I handle
995 it manually now so that people can use this
996 with 5.9.5/bleadperl without issue.
998 0.40 Tues, July 3, 2007
1000 ~ marked a test in 003_methods.t as TODO
1001 for perl 5.9.5 (this test is irrelvant to
1002 the module functioning on 5.9.5 for the most
1005 0.39 Mon. June 18, 2007
1006 * Class::MOP::Immutable
1007 - added make_metaclass_mutable + docs (groditi)
1008 - removed unused variable
1009 - added create_immutable_transformer
1010 necessary for sane overloading of immutable behavior
1011 - tests for this (groditi)
1014 - Immutability can now be undone,
1015 added make_mutable + tests + docs (groditi)
1016 - Massive changes to the way Immutable is done
1017 for details see comments next to make_immutable
1018 This fixes a bug where custom metaclasses broke
1019 when made immutable. We are now keeping one immutable
1020 metaclass instance per metaclass instead of just one
1021 to prevent isa hierarchy corruption. Memory use will go
1022 up, but I suspect it will be neglible.
1023 - New tests added for this behavior. (groditi)
1025 0.38 Thurs. May 31, 2007
1026 ~~ More documentation updates ~~
1028 * Class::MOP::Package
1029 - we now deal with stub methods properly

1034 - added get_read_method and get_write_method
1035 thanks to groditi for this code, tests
1037 - added tests and POD for this
1040 - fixed RT issue #27329, clone object now
1041 handles undef values correctly.
1042 - added tests for this
1043 - Corrected anon-class handling so that they
1044 will not get reaped when instances still
1045 exist which need to reference them. This is
1046 the correct behavior, hopefully this is an
1047 obscure enough feature that there are not too
1048 many work arounds out in the wild.
1049 - added tests for this by groditi
1050 - updated docs to explain this
1053 - load custom metaclasses automatically (thanks groditi)
1054 - added tests for this behavior
1056 0.37 Sat. March 10, 2007

1065 avoid setting off bool-overloads (found by Carl Franks)
1069 - bad name in a test, causing meaningless failuress.
1074 ~~ GLOBAL CHANGES ~~
1075 - All attribute names are now consistent and follow Perl 6
1076 style (prefixed with the sigil, and ! as the twigil for
1077 private attrs). This should not affect any code, unless
1078 you broke encapsulation, in which case, it is your problem
1081 !! Class::MOP::Class::Immutable has been removed
1083 * Class::MOP::Method::Constructor
1084 - this has been moved out of Class::MOP::Class::Immutable
1085 and is a proper subclass of Class::MOP::Method now.
1088 - this module now uses Class::MOP::Immutable for the
1089 immutable transformation instead of
1090 Class::MOP::Class::Immutable.
1092 + Class::MOP::Immutable
1093 - this module now controls the transformation from a mutable
1094 to an immutable version of the class. Docs for this will
1095 be coming eventually.
1098 0.36 Sun. Nov. 5, 2006
1100 - added a few 'no warnings' lines to keep annoying
1101 (and meaningless) warnings from chirping during
1105 - some more bootstrapping is now done on the new
1108 * Class::MOP::Class::Immutable
1110 - constructor generation is now handled by
1111 the Class::MOP::Method::Constructor class
1113 * Class::MOP::Method::Constructor
1114 - created this to handle constructor generation
1115 in Class::MOP::Class::Immutable
1117 * Class::MOP::Attribute
1119 - attributes now delegate to the
1120 Class::MOP::Method::Accessor to generate
1123 * Class::MOP::Method::Accessor
1124 - all accessor generation functions from
1125 Class::MOP::Attribute have been moved here

1141 - adjusted tests for this
1142 - added the Class::MOP::Instance attributes

1149 - adjusted tests to compensate
1150 - adjusted docs for this
1153 - changed how methods are dealt with to
1154 encapsulate most of the work into the
1155 &get_method_map method
1156 - made several adjustments for the change
1157 in Class::MOP::Method
1158 - &add_attribute now checks if you are adding
1159 a duplicate name, and properly removes the
1160 old one before installing the new one
1161 - added tests for this
1162 - adjusted docs for this
1164 * Class::MOP::Class::Immutable
1165 - added caching of &get_method_map

1171 &list_all_package_symbols
1173 0.34 Sat. Aug. 26, 2006
1175 - added the %:methods attribute, which like
1176 the $:version and such just actually goes
1177 to the symbol table to get it's stuff.
1178 However, it makes the MOP more complete.
1180 - The &create method now requires that all
1181 but the package name now is passed in as
1182 named parameters. See docs for more info.
1183 - updated docs and tests for this
1185 * Class::MOP::Object
1186 - added &dump method to easily Data::Dumper

1208 are no longer allowed for defaults
1209 - added tests for this
1211 * Class::MOP::Package
1212 - fixed an issue with perl 5.8.1 and how it deals
1213 with symbol tables. The namespace hash is now
1214 always reloaded from the symbol table.
1216 ~ lots of misc. documentation cleanup
1218 0.32 Sat. Aug. 12, 2006
1219 + added Class::MOP::Object so that the
1220 metamodel is more complete (and closer
1221 to what Perl 6 will probably be).

1225 the primary gateway between the metaclass
1226 and the Perl 5 symbol table
1227 - added many tests for this

1234 use Class::MOP::Package methods instead
1236 * Class::MOP::Module
1237 - adding the $:version attribute in the bootstrap
1238 so that Module has a version as an attribute
1239 - see comment in Class::MOP for details
1240 - added the $:authority attribute to this module
1241 as well as an &identifier method, to bring us
1242 ever closer to Perl 6 goodness
1243 - I have added $AUTHORITY to all the modules
1244 - added tests for this

1263 - added &set_value and &get_value for getting
1264 the value of the attribute for a particular
1267 0.30 Wed. July 5, 2006
1268 ---------------------------------------
1269 This is the first version of Class::MOP
1270 to introduce the immutable features which
1271 will be used for optimizating the MOP.
1272 This support should still be considered
1273 experimental, but moving towards stability.
1274 ---------------------------------------
1276 * Created Class::MOP::Class::Immutable
1278 * Created the Class::MOP::Package and
1279 Class::MOP::Module classes to more
1280 closely conform to Perl 6's meta-model
1283 - now inherits from Class::MOP::Module
1284 - several methods moved to ::Module and
1285 ::Package and now inherited
1286 - added tests for this
1288 * Class::MOP::Instance
1289 - added an is_inlinable method to allow other
1290 classes to check before they attempt to optimize.
1291 - added an inline_create_instance to inline
1292 instance creation (of course)
1295 - the Class::MOP::Class::*_package_variable
1296 methods are all now methods of Class::MOP::Package
1297 and called *_package_symbol instead. This is
1298 because they are now more general purpose symbol
1299 table manipulation methods.
1301 0.29_02 Thurs. June 22, 2006
1302 ++ DEVELOPER RELEASE ++
1304 - small change in &create so that it behaves

1361 of the attribute itself, and construct_instance now
1362 delegates appropriately
1364 * Class::MOP::Attribute

1448 0.10 Tues Feb. 14, 2006
1449 ** This release was mostly about writing more tests and
1450 cleaning out old and dusty code, the MOP should now
1451 be considered "ready to use".
1453 - adding more tests to get coverage up a little higher,
1454 mostly testing errors and edge cases.
1455 - test coverage is now at 99%
1458 - no longer optionally exports to UNIVERSAL::meta or
1459 creates a custom metaclass generator, use the
1460 metaclass pragma instead.
1463 - fixed a number of minor issues which came up in the
1464 error/edge-case tests
1466 * Class::MOP::Attribute
1467 - fixed a number of minor issues which came up in the
1468 error/edge-case tests
1471 - fixing the AttributesWithHistory example, it was broken.

1475 - adding new metaclass pragma to make setting up the
1476 metaclass a little more straightforward
1479 - clean up bootstrapping to include more complete
1480 attribute definitions for Class::MOP::Class and
1481 Class::MOP::Attribute (accessors, readers, writers,
1482 etc.) ... it is redundant, but is useful meta-info
1486 - fixing minor meta-circularity issue with &meta, it
1487 is now more useful for subclasses
1488 - added &get_attribute_map as an accessor for the
1489 hash of attribute meta objects
1490 - &compute_all_applicable_attributes now just returns
1491 the attribute meta-object, rather than the HASH ref
1492 since all the same info can be gotten from the
1493 attribute meta-object itself
1494 - updated docs & tests to reflect
1495 - added &clone_instance method which does a deep clone
1496 of the instance structure created by &construct_instance
1497 - added docs & tests for this
1498 - added Clone as a dependency
1499 - added &new_object and &clone_object convience methods to
1500 return blessed new or cloned instances
1501 - they handle Class::MOP::Class singletons correctly too
1502 - added docs & tests for this
1503 - cleaned up the &constuct_class_instance so that it behaves
1504 more like &construct_instance (and managed the singletons too)
1505 - added the &check_metaclass_compatibility method to make sure
1506 that metaclasses are upward and downward compatible.
1507 - added tests and docs for this
1510 - adjusting code to use the &Class::MOP::Class::meta
1512 - adjusting code to use the metaclass pragma
1514 0.05 Sat Feb. 4, 2006
1516 - added the &attribute_metaclass and &method_metaclass
1517 attributes which contain a metaclass name to use for
1518 attributes/methods respectively
1521 - bootstrap additional attributes for Class::MOP::Class
1524 - adjusted the example code and tests to use the new
1525 &attribute_metaclass feature of Class::MOP::Class
1526 - added new example:
1529 0.04 Fri Feb. 3, 2006
1531 - some documentation suggestions from #perl6
1533 * Class::MOP::Attribute
1534 - improved error messages
1537 - added new examples:
1538 - AttributesWithHistory
1539 - ClassEncapsultedAttributes
1541 0.03 Fri Feb. 3, 2006
1542 - converted to Module::Build instead of EU::MM
1544 * Class::MOP::Attribute
1545 - refactored method generation code
1546 - attributes are now associated with class directly
1549 - refactored the InsideOut example to take advantage
1550 of the Class::MOP::Attribute refactoring
1551 - changed example files to .pod files and hide thier
1552 package names from PAUSE (I don't want to own these
1553 namespaces really, they are just examples)
1555 0.02 Thurs Feb. 2, 2006
1556 - moving examples from t/lib/* to examples/*
1557 - adding POD documentation to the examples
