1 Revision history for Perl extension Class-MOP.
5 - Applied an MS VC++ compilation fix from Taro Nishino. RT #48072
8 - The load_class function just returns true, since it's return value was
9 confusing (either a metaclass object or a class name). It either loads
10 a class or dies trying. In the future, this may change to not return
11 anything, since there's no point in checking its return
12 value. Addresses RT #45883. (Dave Rolsky)
14 * Class::MOP::Class::Trait::Immutable
15 - When throwing an error because of an immutable method, include that
16 method's name. Addresses RT #49680. (Shawn M Moore)
19 - Fixed a bug where adding the same sub reference to multiple packages
20 failed to update the method map properly. RT #48985. Reported by Paul
22 - The get_method_map method is now private. The public version is
23 available as a deprecated method, but the values of the hash reference
24 may now be either Class::MOP::Method objects _or_ raw sub
25 references. (Dave Rolsky)
27 0.92_01 Thu, Sep 10, 2009
29 - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
32 - Make sure XS code handles magical scalars correctly. (Goro Fuji)
35 - Documented the immutable_options method, which is useful if you need
36 to make a class mutable temporarily, and then nede to restore
37 immutability. (Dave Rolsky)
40 - Deprecated features have been moved to their own module,
41 Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)
46 - Move get_method_map and its various scaffolding into Package. (hdp)
49 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
50 the first argument, rather than just a coderef. (doy)
52 * Class::MOP::Attribute
54 - Allow attribute names to be false (while still requiring them to be
58 * Class::MOP::Method::Wrapped
59 - Fixing variable usage issues with the patch from previous
60 version, not properly using lexicals in the for
64 Japan Perl Association has sponsored Goro Fuji to improve startup
65 performance of Class::MOP and Moose. These enhancements may break
66 backwards compatibility if you're doing (or using) complex
67 metaprogramming, so, as always, test your code!
68 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
72 - Anonymous classes were not completely destroyed when they went
73 out of scope, leading to a memory leak. RT #47480. (Goro
77 - The get_method, has_method, and add_method methods no longer
78 use get_method_map. Method objects are instantiated
79 lazily. This significantly improves Class::MOP's load
83 - Inline fewer metaclass-level constructors since the ones we
84 have are perfectly fine. This reduces the number of string
87 * Class::MOP::Method::Wrapped
88 - If a method modifier set $_, this caused the modifier to blow
89 up, because of some weird internals. (Jeremy Stashewsky)
93 * Class::MOP::Class::Immutable::Trait
94 - Made the Trait act like a role with a bunch of "around"
95 modifiers, rather than sticking it in the inheritance
96 hierarchy. This fixes various problems that caused with
97 metaclass compatibility, which broke Fey::ORM.
100 - Allow a blessed code reference as the method body. Fixes a
101 problem interaction with MooseX::Types. (ash)
103 * Class::MOP::Instance
104 - add inline version of rebless_instance_structure. (doy)
105 - change inline_slot_access to use single quotes (gphat)
107 0.88 Tue, Jun 23, 2009
109 - Moved the __INSTANCE__ parameter to _construct_instance from
111 - Fixed some issues involving metaclasses of metaclasses and
114 0.87 Sun, Jun 21, 2009
116 - Made sure to always local-ize $@ and $SIG{__DIE__} before
117 calling an eval. Fixes RT #45973.
120 - Synced docs about immutability with the current reality (which
121 changed back in 0.82_01)
122 - Removed the immutable_transformer method, which had been
123 returning undef since 0.82_01 anyway.
126 - Got rid of tests which needed Moose and improved testing of
127 constructor/destructor inlining warnings. Fixes RT #47119.
129 0.86 Tue, Jun 16, 2009
131 - If you redefined a subroutine at runtime and then wrapped it
132 with a method modifier, the modifier could in some cases wrap
133 the original version of the subroutine. Fixes RT #46957.
136 - make_immutable issues a warning instead of overriding an
137 existing DESTROY method (Dylan William Hardison). Fixes RT
140 0.85 Sat, Jun 6, 2009
141 * Class::MOP::Attribute
142 - Allow default values to be Class::MOP::Methods. (Florian
144 - Test the above. (Rhesa Rozendaal)
145 - Tweak original commit so the intent matches the accepted
146 behavior (Nicholas Perez)
149 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
152 - Add direct_subclasses method (Sartak)
153 - Tests for subclasses and direct_subclasses (Sartak)
154 - subname is no longer used unconditionally in add_method, but
155 only if the code reference's name is '__ANON__' (nothingmuch)
156 - Add a hook for _superclasses_updated (Sartak)
159 - Remove long, old warning about possibly outdated modules
162 0.84 Tue, May 12, 2009
164 - Depend on Text::Exception 0.27 to avoid failing tests ond old
168 - Made is_class_loaded a little stricter. It was reporting that
169 a class was loaded if it merely had an @ISA variable in its
170 stash. Now it checks that the @ISA var has elements in it.
171 - Deprecate in_global_destruction and subname re-exporting
175 - Explicitly use Devel::GlobalDestruction and Sub::Name
178 * Class::MOP::Package
179 - Disable prototype mismatch warnings for add_package_symbol.
182 - Add test for finding methods from $meta->name->meta before immutable,
185 0.83 Mon, April 27, 2009
187 - Fix segfault when calling get_method_map on a metaclass for an empty
190 0.82_02 Fri, April 24, 2009
191 * Class::MOP::Method::Inlined
192 - Don't inline if the expected method is not defined at all (happens with
193 e.g. Moose::Object::_new is the expected method due to an overridden
196 - Some tests were trying to load Class::MOP::Immutable, which
197 was removed in 0.82_01.
199 0.82_01 Thu, April 23, 2009
200 * Class::MOP::Immutable (and others)
201 - Refactor the immutability system to use a pre-defined class
202 for the immutable metaclass of Class::MOP::Class::Immutable::$class
203 - Rather than generating methods into this class every time, use
204 a Trait (basic mixin) to supply the cached methods
205 - Remove the hack that returns the mutable metaclass for
206 metacircularity in order to provide consistent meta-metaclasses
207 for the Moose compatibility handling code
208 (mst broke it, nothingmuch fixed it)
210 0.82 Mon, April 20, 2009
212 - The deprecation wrappers for some renamed methods were not
213 passing arguments to the new method. (nothingmuch)
215 * Class::MOP::Immutable
216 - Warn during immutablization if the local class provides its own
217 constructor, to parallel the warning in Moose when a superclass
218 provides its own constructor (doy)
220 0.81 Tue, April 7, 2009
223 * Class::MOP::Instance
224 * Class::MOP::Attribute
225 * Class::MOP::Method::Accessor
226 * Class::MOP::Method::Constructor
227 - Include stack traces in the deprecation warnings introduced in
228 0.80_01. (Florian Ragwitz)
231 - Avoid c compiler warnings by declaring some unused function
232 arguments. (Florian Ragwitz)
234 0.80_01 Sun, April 5, 2009
236 - Make sure to preserve any compiler flags already defined in
237 Config.pm. Patch by Vincent Pit. RT #44739.
239 * Many methods have been renamed with a leading underscore, and a
240 few have been deprecated entirely. The methods with a leading
241 underscore are consider "internals only". People writing
242 subclasses or extensions to Class::MOP should feel free to
243 override them, but they are not for "public" use.
246 - construct_class_instance => _construct_class_instance (use new_object)
247 - construct_instance => _construct_instance (use new_object)
248 - check_metaclass_compatibility => _check_metaclass_compatibility
249 - create_meta_instance => _create_meta_instance (use get_meta_instance)
250 - clone_instance => _clone_instance (use clone_object)
251 - compute_all_applicable_methods is deprecated, use get_all_methods
252 - compute_all_applicable_attributes is deprecated, use get_all_attributes
254 - Class::MOP::Instance
255 - bless_instance_structure is deprecated and will be removed
259 - create has been renamed to _instantiate_module. This method
260 does not construct an object, it evals some code that
261 creates the relevant package in Perl's symbol table.
263 - Class::MOP::Method::Accessor
264 - initialize_body => _initialize_body (this is always called
265 when an object is constructed)
266 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
268 - Class::MOP::Method::Constructor
269 - initialize_body => _initialize_body (this is always called
270 when an object is constructed)
271 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
272 - attributes => _attributes
273 - meta_instance => _meta_instance
275 0.80 Wed, April 1, 2009
277 - Call user_class->meta in fewer places, with the eventual goal
278 of allowing the user to rename or exclude ->meta
279 altogether. Instead uses Class::MOP::class_of. (Sartak)
282 - New class_of function that should be used to retrieve a
283 metaclass. This is unlike get_metaclass_by_name in that it
284 accepts instances, not just class names. (Sartak)
287 - load_first_existing_class didn't actually load the first
288 existing class; instead, it loaded the first existing and
289 compiling class. It now throws an error if a class exists (in
290 @INC) but fails to compile. (hdp)
294 - we had some semi-buggy code that purported to provide a
295 HAS_ISAREV based on whether mro had get_isarev (due to an
296 oversight, it always returned 1). Since mro and MRO::Compat
297 have always had get_isarev, HAS_ISAREV was pointless. This
298 insight simplified the subclasses method by deleting the
299 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
301 0.79 Fri, March 29, 2009
302 * No changes from 0.78_02.
304 0.78_02 Thu, March 26, 2009
306 * Class::MOP::Immutable
307 - A big backwards-incompatible refactoring of the Immutable API,
308 and the make_immutable/make_mutable pieces of the Class
309 API. The core __PACKAGE__->meta->make_immutable API remains
310 the same, however, so this should only affect the most
314 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
315 has been fixed to be backwards compatible with 5.8.x.
318 - Add a hook for rebless_instance_away (Sartak)
319 - Use blessed instead of ref to get an instance's class name
320 in rebless_instance. (Sartak)
322 0.78_01 Wed, March 18, 2009
324 - Revised and reorganized all of the API documentation. All
325 classes now have (more or less) complete API documentation.
328 * Class::MOP::Instance
329 - Reblessing into a package that supports overloading wasn't
330 properly adding overload magic to the object due to a bug
331 in (at least) 5.8.8. We now use $_[1] directly which seems
332 to set the magic properly. (Sartak)
334 * Class::MOP::Attribute
335 - The process_accessors method is now private. A public alias
336 exists (and will stick around for a few releases), but it
337 warns that calling the public method is deprecated.
339 * Class::MOP::Method::Generated
340 - Removed the new and _new methods, since this is an abstract
341 base class, and all existing subclasses implement their own
345 - Stop is_class_loaded from thinking a class is loaded if it
346 only has an empty GV (Florian Ragwitz).
347 - Add a test for this (Yappo).
348 - Refactor get_all_package_symbols to allow short-circuiting
350 - Use this in is_class_loaded (Florian Ragwitz).
351 - Stop segfaulting when trying to get the name from a sub that's
352 still being compiled (Florian Ragwitz).
353 - Add tests for this (Florian Ragwitz).
354 - Prefix all public symbols with "mop_" (Florian Ragwitz).
355 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
356 - Simplify creating simple xs reader methods (Florian Ragwitz).
357 - Make everything compile with c++ compilers (Florian Ragwitz).
358 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
361 - Remove optional test plans for tests depending on Sub::Name as
362 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
365 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
367 0.78 Mon, February 23, 2009
368 * No changes from 0.77_01
370 0.77_01 Sun, February 22, 2009
372 - This package now requires its XS components. Not using
373 Sub::Name lead to different behavior and bugginess in the pure
374 Perl version of the code. A Moose test would fail when run
375 against the pure Perl version of this code.
377 * Class::MOP::Instance
378 - The inline_* methods now quote attribute names themselves, and
379 don't expect to receive a quoted value.
382 0.77 Sat, February 14, 2009
384 - Avoid assertion errors on debugging perls in is_class_loaded
388 - Fixed various corner cases where is_class_loaded incorrectly
389 returned true for a class that wasn't really loaded. (Dave
393 - Add get_all_method_names (Sartak)
394 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
396 * Class::MOP::Package
397 - Disable deprecated get_all_package_symbols in list
398 context. (Florian Ragwitz)
401 - Make sure we generate a BSD-compatible Makefile (Florian
405 - The misspelled "check_metaclass_compatability" method we've
406 kept around for backwards compat_i_bility will be removed in a
407 near future release. You've been warned.
409 0.76 Thu, January 22, 2009
410 * Class::MOP::Method::Generated
411 - Added new private methods to support code generation, which
412 are being used by Moose and can be used by MooseX
414 - Generated methods are now generated with a #line directive
415 reflecting the source of the generated method. (nothingmuch)
418 - Clarified documentation of methods that return
419 Class::MOP::Method objects. (doy)
422 - Clarified documentation of the metaclass cache methods. (Sartak)
425 - Add test showing how the xs Class::MOP::is_class_loaded can
426 be made to operate differently to the pure perl version (t0m)
428 0.75 Wed, December 31, 2008
430 - A class that was made immutable and then mutable could end up
431 sharing an immutable transformer object
432 (Class::MOP::Immutable) with other classes, leading to all
433 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
435 0.74 Tue, December 25, 2008
437 - Add an xs implementation of Class::MOP::is_class_loaded (closes
438 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
439 - Changed internals to make prehashing of hash keys easier and less
440 error-prone. (Florian Ragwitz)
442 - Fix documentation to show that around modifiers happen on both
443 sides of the modified method. (Dave Rolsky)
445 0.73 Tue, December 16, 2008
447 - Don't use Perl_mro_meta_init. It's not part of the public perl
448 api. Fixes failures to build on Win32 (RT #41750). (Florian
450 * t/082_get_code_info.t
451 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
452 munger anonymous subs when under -d and so making the tests
453 succeed in that case.
455 0.72 Mon, December 8, 2008
456 * Class::MOP::Package
457 - Pass options to _new, so subclass' attributes can be
460 - In the docs, indicate that package_name and name are required
461 when calling ->wrap (Stefan O'Rear)
463 0.71_02 Fri, December 5, 2008
464 * Class::MOP::Immutable
465 - Added a new attribute, inlined_constructor, which is true if
466 the constructor was inlined.
467 * Class::MOP::Package
468 - Make get_all_package_symbols return a hash ref in scalar
469 context and deprecate calling it in list context with a
470 warning. (Florian Ragwitz)
472 - Various improvements and refactoring, making things more robust and
473 easier to maintain. (Florian Ragwitz)
475 0.71_01 Wed, December 3, 2008
477 - Add an "execute" method to invoke the body so
478 we can avoid using the coderef overload (Sartak)
479 * Class::MOP::Immutable
480 - When we memoize methods, get their results lazily
481 to remove some compile-time cost (Sartak)
482 - Small speedup from eliminating several method
485 - Some small internal tweaks to try to reduce the number of
486 times we call get_method_map when bootstrapping the MOP. This
487 might make loading Class::MOP (and Moose) a little
488 faster. (Dave Rolsky)
489 - Implemented an optional XS version of get_method_map. Mostly
490 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
491 help form Florian Ragwitz. (Dave Rolsky)
492 - Make the behaviour of of get_all_package_symbols (and
493 therefore get_method_map) consistent for stub methods. Report
494 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
496 0.71 Wed November 26, 2008
499 - Actual package creation has moved upward from
500 Class to Module so that Moose roles can share
503 0.70_01 Mon, November 19, 2008
505 - Fixes for failures with blead (Florian Ragwitz)
506 - Silenced compiler warnings (Florian Ragwitz)
508 0.70 Fri, November 14, 2008
510 - Fixed an odd corner case where the XS version of
511 get_all_package_symbols could cause a segfault. This only
512 happened with inlined constants in Perl 5.10.0 (Florian
515 0.69 Fri, November 7, 2008
516 * Class::MOP::Method::Wrapped
517 - Added introspection methods for method modifiers (Dave Rolsky)
520 0.68 Fri October 24, 2008
522 - Make load_class require by file name instead of module name.
523 This stops confusing error messages when loading '__PACKAGE__'.
525 - Add load_one_class_of function to enable you to load one of a
526 list of classes, rather than having to call load_class multiple
527 times in an eval. (t0m)
529 0.67 Tue October 14, 2008
531 - Call a method on the class after setting the superclass list
532 so that we can get Perl to detect cycles before MRO::Compat
533 spirals into an infinite loop (sartak)
534 - Reported by Schwern, [rt.cpan.org #39001]
535 - In create(), pass unused options on to initialize()
536 - added test for this
538 0.66 Sat September 20, 2008
539 !! This release has an incompatible change regarding !!
540 introspection of a class's method with Class::MOP::Class !!
543 - We (us maintainers) now run all tests with XS and then without
544 XS, which should help us catch skew between the XS/pure Perl
548 ! The alias_method method has been deprecated. It now simply
549 calls add_method instead. There is no distinction between
550 aliased methods and "real" methods.
552 This means that methods added via alias_method now show up as
553 part of the class's method list/map. This is a backwards
554 incompatible change, but seems unlikely to break any
555 code. Famous last words. (Dave Rolsky)
558 - Fixed the spelling of "compatibility", but we still have a
559 "check_metaclass_compatability" method for backwards
562 0.65 Mon September 1, 2008
563 For those not following the series of dev releases, the changes
564 from 0.64 from 0.65 can mostly be summed up as a lot performance
565 improvements by nothingmuch, including new optional XS versions of
566 some methods. Also, Class::MOP now works _without_ any XS modules,
567 for sad systems without a compiler.
570 - Added name and package_name XS accessors, and make sure all
571 the XS and Perl versions work the same way. (Dave Rolsky)
574 - The XS versions of various methods just returned undef when
575 called class methods, rather than dying like the pure Perl
576 versions. (Dave Rolsky)
578 0.64_07 Fri August 29, 2008
580 - Silenced warnings that managed to break Moose tests when XS
581 was loaded. (Dave Rolsky)
582 - Some XS versions of methods were ignored because of typos in
583 MOP.xs. (Dave Rolsky)
585 0.64_06 Mon August 25, 2008
586 * Class::MOP (MOP.xs)
587 - Another MS VC++ fix, cannot declare a variable in the middle
588 of a scope (Taro Nishino).
590 0.64_05 Sun August 24, 2008
592 - None of the dev releases actually loaded the XS properly, but
593 we silently fell back to the pure Perl version of the
596 * Class::MOP (MOP.xs)
597 - Replaced some code that used functions not available on Visual
598 C++ with some Perl XS API bits (Dave Rolsky).
600 0.64_04 Sat August 23, 2008
602 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
604 * pod.t and pod_coveraget.t
605 - These are no longer shipped with the tarball because of bogus
606 failures from CPAN testers. (Dave Rolsky)
608 0.64_03 Thu August 21, 2008
609 * Class::MOP::Package
610 - Some (legit) code was misparsed by earlier 5.8.x
611 releases. (nothingmuch)
614 - Fix a constant in void context warning (nothingmuch)
616 0.64_02 Thu August 21, 2008
617 * Makefile.PL and Class::MOP
618 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
621 - Add missing prereqs that got lost in the switch away from
624 * Class::MOP::Instance
625 - New method - get_all_attributes (nothingmuch)
627 0.64_01 Wed August 20, 2008
629 - We now check to see if you have a compiler. If you don't, the
630 module installs without some XS bits, but will work the same
631 as with XS. This should make it easier to install on platforms
632 without a compiler (like Windows). (Dave Rolsky)
635 - Perl 6 style attribute naming replaced with sane style ('methods', not
636 '%!methods'). These changes should not impact any existing API uses.
640 - Quite a number of optimizations based on profiling, including
641 allowing constructors to take hash references instead of
642 hashes, duplicating some frequently used code in XS, and
643 making constructors immutable. These changes should not impact
644 any existing API uses. (nothingmuch)
647 - Constructors now respect the meta attributes of their subclasses,
648 facilitating MOP extensibility. More related changes will happen in the
649 next several releases. (nothingmuch)
652 - New method - get_all_methods, replaces the deprecated
653 compute_all_applicable_methods. get_all_attributes provided for
654 consistency (nothingmuch)
655 - New method - wrap_method was refactored out of get_method_map
657 - New API for meta instance invalidation - invalidate_meta_instance,
658 invalidate_meta_instances, add_dependent_meta_instance,
659 remove_dependent_meta_instance, called automatically when attribute
660 definitions change and allows notification of dependent subclasses.
663 0.64 Sun August 3, 2008
664 * Class::MOP::Immutable
665 - fixing subtle edge case in immutable when you
667 - clean up option processing (nothingmuch)
669 * Class::MOP::Instance
670 - inlined initialize slot didn't match
671 non-inlined (nothingmuch)
673 0.63 Mon July 7, 2008
675 - load_class will initialize a metaclass even if
676 the class is already loaded (sartak)
677 - load_class now returns the metaclass instance
678 instead of just 1 (sartak)
681 - better error messages (sartak and Dave Rolsky)
683 0.62 Wed June 18, 2008
684 - in is_class_loaded, recognize scalar references (as opposed to globs) in
685 the symbol table as methods (these are optimized constant subs)
687 0.61 Fri. June 13, 2008
688 - Okay, lets give this another try and see if PAUSE
689 recognizes it correct this time.
691 0.60 Thurs. Jun 12, 2008
692 - Fixed a version number issue by bumping all modules
695 0.59 Thurs. Jun 12, 2008
696 !! Several fixes resulting in yet another 25-30% speedup !!
699 - now stores the instance of the instance
700 metaclass to avoid needless recomputation
701 and deletes it when the cache is blown
702 - introduce methods to query Class::MOP::Class for
703 the options used to make it immutable as well as
704 the proper immutable transformer. (groditi)
706 * Class::MOP::Package
707 - {add, has, get, remove}_package_symbol all
708 now accept a HASH ref argument as well as the
709 string. All internal usages now use the HASH
713 - MOP.xs does sanity checks on the coderef
715 - is_class_loaded check now uses code that
716 was improved in Moose's ClassName type
718 - nonsensical (undef, empty, reference) class
719 names now throw a more direct error in
721 - tests for this and other aspects of
727 Class::MOP::Method::Wrapped
728 Class::MOP::Attribute
729 - switched usage of reftype to ref because
732 0.58 Thurs. May 29, 2008
733 (late night release engineering)--
735 - fixing the version is META.yml, no functional
736 changes in this release
738 0.57 Wed. May 28, 2008
739 !! Several speedups resulting in 20-25% speedups !!
740 || (thanks to konobi, groditi, mst & CataMoose) !!
743 - made get_method_map use list_all_package_symbols
744 instead of manually grabbing each symbol
745 - streamlining &initialize somewhat, since it gets
748 * Class::MOP::Package
749 - made {get, has}_package_symbol not call
751 - inlining a few calls to &name with
752 direct HASH access key access
753 - added get_all_package_symbols to fetch
754 a HASH of items based on a type filter
755 similar to list_all_package_symbols
756 - added tests for this
759 Class::MOP::Method::Constructor
760 Class::MOP::Method::Generated
761 Class::MOP::Method::Accessor
762 - added more descriptive error message to help
763 keep people from wasting time tracking an error
764 that is easily fixed by upgrading.
766 * Class::MOP::Immutable
767 - Don't inline a destructor unless the user actually
769 - added tests for this
771 0.56 Saturday, May 24, 2008
773 - we now get the &check_package_cache_flag
774 function from MRO::Compat
775 - All XS based functionality now has a
776 Pure Perl alternative
777 - the CLASS_MOP_NO_XS environment variable
778 can now be used to force non-XS versions
781 * Class::MOP::Attribute
782 - add has_read_method and has_write_method
783 - get_{read,write}_method_ref now wraps the
784 anon-sub ref in the method metaclass when
786 - added tests for this
788 * Class::MOP::Immutable
789 - added the ability to "wrap" methods when
790 making the class immutable
793 - now handling the edge case of ->meta->identifier
794 dying by wrapping add_package_symbol to specifically
795 allow for it to work.
796 - added tests for this
798 * Class::MOP::Attribute
800 Class::MOP::Immutable
801 - any time a method meta object is constructed
802 we make sure to pass the correct package and
803 method name information
806 Class::MOP::Method::Wrapped
807 Class::MOP::Method::Generated
808 Class::MOP::Method::Accessor
809 Class::MOP::Method::Consructor
810 - the &wrap constructor method now requires that a
811 'package_name' and 'name' attribute are passed. This
812 is to help support the no-XS version, and will
813 throw an error if these are not supplied.
814 - all these classes are now bootstrapped properly
815 and now store the package_name and name attributes
818 ~ Build.PL has been removed since the
819 Module::Install support has been removed
821 0.55 Mon. April 28, 2008
822 - All classes now have proper C3 MRO support
823 - added MRO::Compat as a dependency to allow
824 for the C3 MRO support to Just Work in all
828 - rebless_instance now returns the instance
829 it has just blessed, this is mostly to
831 - set the attr correctly in rebless_instance
832 when it has no init_arg
833 - tweaked &linear_isa and &class_precedence_list
834 to support c3 classes.
836 0.54 Fri. March, 14, 2008
839 - making sure that load_class never gets
840 passed a value from @_ or $_ to squash
841 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
844 - make_{immutable,mutable} now return 1
846 - improved error handling in ->create method
847 - rebless_instance now takes extra params which
848 will be used to populate values
849 - added tests for this
852 - localizing the Data::Dumper configurations so
853 that it does not pollute others (RT #33509)
859 Class::MOP::Attribute
860 - these classes no longer define their own ->meta,
861 but instead just inherit from Class::MOP::Object
863 * Class::MOP::Instance
864 Class::MOP::Immutable
865 - these classes now inherit from Class::MOP::Object
868 - fixed the filename length on several
869 test files so we install on VMS better
871 - fixed incorrect use of catdir when it
872 should be catfile (RT #32385)
874 0.53 Thurs. Feb. 14, 1008
875 ~~ several doc. fixes and updates ~~
878 Class::MOP::Method::Constructor

881 to indicate that no constructor args can
882 be passed (thanks to nothingmuch)
883 - added tests for this
884 - added attribute initializer attribute (rjbs)
887 - making this use the new init_arg => undef
888 feature instead of the silly hack from
889 before (thanks to nothingmuch)
891 0.52 Tues. Jan. 22, 2008
893 - fixed bug in rebless_instance
896 * Class::MOP::Method::Constructor
897 - removed assumptions about the existence of
900 0.51 Mon. Jan. 14, 2008
901 ~~~ some misc. doc. fixes ~~~
902 ~~ updated copyright dates ~~
905 - now sets the IS_RUNNING_ON_5_10
906 constant so that we can take advantage
907 of some of the nice bits of 5.10
910 - uses the IS_RUNNING_ON_5_10 flag to
911 optimize the &linearized_isa method
912 and avoid the hack/check for circular
913 inheritence in &class_precedence_list
914 - added rebless_instance method (Sartak)
915 - added tests for this
917 * Class::MOP::Immutable
918 - the immutable class now keeps track of
919 the transformer which immutablized it
921 * Class::MOP::Instance
922 - added rebless_instance_structure method (Sartak)
923 - added tests for this
925 0.50 Fri. Dec. 21, 2007

928 transformation arguments are saved
930 - added tests for this
932 * Class::MOP::Immutable
933 - fixed a bug (see above)
935 * Class::MOP::Attribute
938 0.49 Fri. Dec. 14, 2007
939 !! Class::MOP now loads 2 x faster !!
940 !! with XS speedups (thanks konobi) !!
943 - removed the dependency on B
944 - added two XS functions (thanks konobi)
945 - get_code_info($code) which replaces all
946 the B fiddling we were doing with
947 faster/leaner XS level fiddling
948 - check_package_cache_flag($pkg_name) which
949 returns the PL_sub_generation variable to
950 be used to help manage method caching.
953 In 5.10 or greater this will actually
954 use the mro::get_pkg_gen instead to give
955 even more accurate caching information.
956 blblack++ for that stuff :)
959 - added the &subclasses method (thanks rlb)
960 - added the update_package_cache_flag and
961 reset_package_cache_flag which help keep
962 track of when we need to re-fetch the
964 - Several small improvements to take advantage
965 of the new method map caching features
967 0.48 Mon. Nov. 26, 2007
968 * Class::MOP::Attribute
969 - fixed get_read/write_method to handle the
970 HASH ref case, which makes the
971 get_read/write_method_ref handle it too.
972 - added more tests for this
974 0.47 Sat. Nov. 24, 2007
975 * Class::MOP::Attribute
976 - fixed misspelling in get_write_method_ref
977 - added more tests for this
979 0.46 Fri. Nov. 23, 2007
981 - added the linearized_isa method instead of constantly
982 pruning duplicate classes (this will be even more
983 useful in the 5.10-compat version coming soon)
985 * Class::MOP::Attribute
986 - added the get_read_method_ref and get_write_method_ref
987 methods which allow you to retrieve a CODE ref which
988 can always be used to read or write an attribute.
990 0.45 Thurs. Nov. 13, 2007
991 * Class::MOP::Attribute
992 - Fix error message on confess (groditi)
994 0.44 Thurs. Nov. 13, 2007

1005 call through (groditi)
1007 * Class::MOP::Attribute
1008 - Add support for the 'builder' attribute (groditi)

1010 it is defined (groditi)
1012 * Class::MOP::Instance
1013 - Make predicates check for the existence of a value, not whether
1014 it is defined (groditi)
1016 * Class::MOP::Method::Accessor
1017 - made this a subclass of Class::MOP::Method::Generated
1018 - removed the relevant attributes
1020 * Class::MOP::Method::Constructor
1021 - fixed the cached values we had to be more sane
1022 - made this a subclass of Class::MOP::Method::Generated
1023 - fixed generated constructor so it properly handles
1025 - added tests for this
1026 - added the option to allow for both inlined and
1027 non-inlined constructors.
1028 - Update inlined methods for builder and predicate changes (groditi)
1030 * Class::MOP::Method::Generated
1031 - added this class as an abstract base for the
1032 Class::MOP::Method::{Constructor,Accessor} classes
1033 - added tests for this
1036 - Alter tests (005, 014 020, 021) for new builder addition (groditi)

1045 * Class::MOP::Package
1046 - alter symbol table handling to deal with 5.8.x and 5.9.x
1049 - Get rid of the crappy workaround from 0.40/41
1051 0.41 Sun. July 15, 2007
1053 Arghh!!! My TODO test didn't work, so I handle
1054 it manually now so that people can use this
1055 with 5.9.5/bleadperl without issue.
1057 0.40 Tues, July 3, 2007
1059 ~ marked a test in 003_methods.t as TODO
1060 for perl 5.9.5 (this test is irrelvant to
1061 the module functioning on 5.9.5 for the most
1064 0.39 Mon. June 18, 2007
1065 * Class::MOP::Immutable
1066 - added make_metaclass_mutable + docs (groditi)
1067 - removed unused variable
1068 - added create_immutable_transformer
1069 necessary for sane overloading of immutable behavior
1070 - tests for this (groditi)
1073 - Immutability can now be undone,
1074 added make_mutable + tests + docs (groditi)
1075 - Massive changes to the way Immutable is done
1076 for details see comments next to make_immutable
1077 This fixes a bug where custom metaclasses broke
1078 when made immutable. We are now keeping one immutable
1079 metaclass instance per metaclass instead of just one
1080 to prevent isa hierarchy corruption. Memory use will go
1081 up, but I suspect it will be neglible.
1082 - New tests added for this behavior. (groditi)
1084 0.38 Thurs. May 31, 2007
1085 ~~ More documentation updates ~~
1087 * Class::MOP::Package
1088 - we now deal with stub methods properly
1089 - added tests for this
1090 - fixed some tests failing on 5.9.5 (thanks blblack)
1092 * Class::MOP::Attribute
1093 - added get_read_method and get_write_method
1094 thanks to groditi for this code, tests
1096 - added tests and POD for this
1099 - fixed RT issue #27329, clone object now
1100 handles undef values correctly.
1101 - added tests for this
1102 - Corrected anon-class handling so that they
1103 will not get reaped when instances still
1104 exist which need to reference them. This is
1105 the correct behavior, hopefully this is an
1106 obscure enough feature that there are not too
1107 many work arounds out in the wild.
1108 - added tests for this by groditi
1109 - updated docs to explain this
1112 - load custom metaclasses automatically (thanks groditi)
1113 - added tests for this behavior
1115 0.37 Sat. March 10, 2007
1116 ~~ Many, many documentation updates ~~
1119 - added &load_class and &is_class_loaded
1120 - added tests and docs for these
1122 * Class::MOP::Attribute
1123 - default now checks the instance with defined to
1124 avoid setting off bool-overloads (found by Carl Franks)
1128 - bad name in a test, causing meaningless failuress.
1133 ~~ GLOBAL CHANGES ~~
1134 - All attribute names are now consistent and follow Perl 6
1135 style (prefixed with the sigil, and ! as the twigil for
1136 private attrs). This should not affect any code, unless
1137 you broke encapsulation, in which case, it is your problem
1140 !! Class::MOP::Class::Immutable has been removed
1142 * Class::MOP::Method::Constructor
1143 - this has been moved out of Class::MOP::Class::Immutable
1144 and is a proper subclass of Class::MOP::Method now.
1147 - this module now uses Class::MOP::Immutable for the
1148 immutable transformation instead of
1149 Class::MOP::Class::Immutable.
1151 + Class::MOP::Immutable
1152 - this module now controls the transformation from a mutable
1153 to an immutable version of the class. Docs for this will
1154 be coming eventually.
1157 0.36 Sun. Nov. 5, 2006
1159 - added a few 'no warnings' lines to keep annoying
1160 (and meaningless) warnings from chirping during
1164 - some more bootstrapping is now done on the new
1167 * Class::MOP::Class::Immutable
1169 - constructor generation is now handled by
1170 the Class::MOP::Method::Constructor class
1172 * Class::MOP::Method::Constructor
1173 - created this to handle constructor generation
1174 in Class::MOP::Class::Immutable
1176 * Class::MOP::Attribute
1178 - attributes now delegate to the
1179 Class::MOP::Method::Accessor to generate
1182 * Class::MOP::Method::Accessor
1183 - all accessor generation functions from
1184 Class::MOP::Attribute have been moved here
1186 0.35 Sat. Sept. 30, 2006
1188 * scripts/class_browser.pl
1189 - initial prototype of a class browser, more
1190 on this to come. Comments and patches are
1194 - All Class::MOP::* accessors are no longer
1195 re-generated in the bootstrap, instead
1196 they are aliased from the originals
1197 - fixed tests to reflect
1198 - added Class::MOP::Method (and its subclasses)
1200 - adjusted tests for this
1201 - added the Class::MOP::Instance attributes
1204 * Class::MOP::Method

1207 but are actual objects which can be CODE-ified
1208 - adjusted tests to compensate
1209 - adjusted docs for this
1212 - changed how methods are dealt with to
1213 encapsulate most of the work into the
1214 &get_method_map method
1215 - made several adjustments for the change
1216 in Class::MOP::Method
1217 - &add_attribute now checks if you are adding
1218 a duplicate name, and properly removes the
1219 old one before installing the new one
1220 - added tests for this
1221 - adjusted docs for this
1223 * Class::MOP::Class::Immutable
1224 - added caching of &get_method_map
1225 - fixed issue with &get_package_symbol
1226 - cleaned up the methods that die (patch by David Wheeler)

1229 - added filtering capabilities to
1230 &list_all_package_symbols
1232 0.34 Sat. Aug. 26, 2006
1234 - added the %:methods attribute, which like
1235 the $:version and such just actually goes
1236 to the symbol table to get it's stuff.
1237 However, it makes the MOP more complete.
1239 - The &create method now requires that all
1240 but the package name now is passed in as
1241 named parameters. See docs for more info.
1242 - updated docs and tests for this
1244 * Class::MOP::Object
1245 - added &dump method to easily Data::Dumper

1266 - reference values (other than CODE refs)
1267 are no longer allowed for defaults
1268 - added tests for this
1270 * Class::MOP::Package
1271 - fixed an issue with perl 5.8.1 and how it deals
1272 with symbol tables. The namespace hash is now
1273 always reloaded from the symbol table.
1275 ~ lots of misc. documentation cleanup
1277 0.32 Sat. Aug. 12, 2006
1278 + added Class::MOP::Object so that the
1279 metamodel is more complete (and closer
1280 to what Perl 6 will probably be).

1283 - refactored entire class, this is now
1284 the primary gateway between the metaclass
1285 and the Perl 5 symbol table
1286 - added many tests for this
1287 - this class is now a subclass of
1289 - added some tests to reflect this

1293 use Class::MOP::Package methods instead
1295 * Class::MOP::Module
1296 - adding the $:version attribute in the bootstrap
1297 so that Module has a version as an attribute
1298 - see comment in Class::MOP for details
1299 - added the $:authority attribute to this module
1300 as well as an &identifier method, to bring us
1301 ever closer to Perl 6 goodness
1302 - I have added $AUTHORITY to all the modules
1303 - added tests for this

1319 anywhere within the class hierarchy
1321 * Class::MOP::Attribute
1322 - added &set_value and &get_value for getting
1323 the value of the attribute for a particular
1326 0.30 Wed. July 5, 2006
1327 ---------------------------------------
1328 This is the first version of Class::MOP
1329 to introduce the immutable features which
1330 will be used for optimizating the MOP.
1331 This support should still be considered
1332 experimental, but moving towards stability.
1333 ---------------------------------------
1335 * Created Class::MOP::Class::Immutable
1337 * Created the Class::MOP::Package and
1338 Class::MOP::Module classes to more
1339 closely conform to Perl 6's meta-model
1342 - now inherits from Class::MOP::Module
1343 - several methods moved to ::Module and
1344 ::Package and now inherited
1345 - added tests for this
1347 * Class::MOP::Instance
1348 - added an is_inlinable method to allow other
1349 classes to check before they attempt to optimize.
1350 - added an inline_create_instance to inline
1351 instance creation (of course)
1354 - the Class::MOP::Class::*_package_variable
1355 methods are all now methods of Class::MOP::Package
1356 and called *_package_symbol instead. This is
1357 because they are now more general purpose symbol
1358 table manipulation methods.
1360 0.29_02 Thurs. June 22, 2006
1361 ++ DEVELOPER RELEASE ++
1363 - small change in &create so that it behaves
1364 properly when inherited
1365 - small fix to &clone_instance
1367 0.29_01 Fri. May 12, 2006
1368 ++ DEVELOPER RELEASE ++
1369 - This release works in combination with
1370 Moose 0.09_01, it is a developer release
1371 because it introduces a new instance
1372 sub-protocol and has not yet been
1376 - anon-classes are now properly garbage collected
1377 - added tests for this
1378 - improved method modifier wrapping

1389 - you no longer need to specify the metaclass
1390 itself, if it is not there, Class::MOP::Class
1392 - updated tests for this
1395 - added ArrayBasedStorage example to show
1396 instance storage using ARRAY refs instead of
1398 - added tests for this

1414 - added create_anon_class for creating anonymous classes
1415 - added tests for this
1416 - added get_all_metaclasses, get_all_metaclass_names
1417 and get_all_metaclass_instances method to allow
1418 access to all the cached metaclass objects.
1419 - attribute slot initialization is now the responsibility
1420 of the attribute itself, and construct_instance now
1421 delegates appropriately
1423 * Class::MOP::Attribute
1424 - attribute slot initialization is now the responsibility
1425 of the attribute itself, so we added a method for it
1426 called initialize_instance_slot
1429 - adjusted all the examples to use the new attribute
1430 initialize_instance_slot method
1432 0.24 Tues. April 11, 2006

1435 modifiers get named with Sub::Name
1437 0.23 Thurs. March 30, 2006
1439 - fixed the way attribute defaults are handled
1440 during instance construction (bug found by chansen)
1442 * Class::MOP::Attribute
1443 - read-only accessors ('reader') will now die if
1444 passed more than one argument (attempting to write
1446 - added tests for this
1447 - adjusted all /example files to comply
1449 0.22 Mon. March 20, 2006
1451 - localized $@ in the *_package_variable functions
1452 because otherwise, it does ugly things in Moose.
1453 - added test case for this
1455 0.21 Wed. March 15, 2006
1457 - fixed issue where metaclasses are reaped from
1458 our cache in global destruction, and so are not
1459 available in DESTORY calls
1461 0.20 Thurs. March 2, 2006
1462 - removed the dependency for Clone since
1463 we no longer to deep-cloning by default.
1465 * Class::MOP::Method
1466 - added &package_name, &name and
1467 &fully_qualified_name methods, some of
1468 which were formerly private subs in
1471 * Class::MOP::Method::Wrapped
1472 - allows for a method to be wrapped with
1473 before, after and around modifiers
1474 - added tests and docs for this feature
1477 - improved &get_package_symbol
1478 - &version and &superclasses now use it
1479 - methods are now blessed into Class::MOP::Method
1481 - added methods to install CLOS-style method modifiers
1482 - &add_before_method_modifier
1483 - &add_after_method_modifier
1484 - &add_around_method_modifier
1485 - added tests and docs for these
1486 - added &find_next_method_by_name which finds the
1487 equivalent of SUPER::method_name
1489 0.12 Thurs. Feb 23, 2006
1490 - reduced the dependency on B, no need to always
1494 - added docs to the C3 method dispatch order test
1495 - fixed missing Algorithm::C3 dependency by making
1496 the test skip if it is not installed
1498 0.11 Mon Feb. 20, 2006
1500 - added example of changing method dispatch order to C3
1503 - changed how clone_instance behaves, it now only does a
1504 shallow clone (see docs for more details)
1505 - added docs and tests
1507 0.10 Tues Feb. 14, 2006
1508 ** This release was mostly about writing more tests and
1509 cleaning out old and dusty code, the MOP should now
1510 be considered "ready to use".
1512 - adding more tests to get coverage up a little higher,
1513 mostly testing errors and edge cases.
1514 - test coverage is now at 99%
1517 - no longer optionally exports to UNIVERSAL::meta or
1518 creates a custom metaclass generator, use the
1519 metaclass pragma instead.
1522 - fixed a number of minor issues which came up in the
1523 error/edge-case tests
1525 * Class::MOP::Attribute
1526 - fixed a number of minor issues which came up in the
1527 error/edge-case tests
1530 - fixing the AttributesWithHistory example, it was broken.
1532 0.06 Thurs Feb. 9, 2006
1534 - adding new metaclass pragma to make setting up the
1535 metaclass a little more straightforward
1538 - clean up bootstrapping to include more complete
1539 attribute definitions for Class::MOP::Class and
1540 Class::MOP::Attribute (accessors, readers, writers,
1541 etc.) ... it is redundant, but is useful meta-info
1545 - fixing minor meta-circularity issue with &meta, it
1546 is now more useful for subclasses
1547 - added &get_attribute_map as an accessor for the
1548 hash of attribute meta objects
1549 - &compute_all_applicable_attributes now just returns
1550 the attribute meta-object, rather than the HASH ref
1551 since all the same info can be gotten from the
1552 attribute meta-object itself
1553 - updated docs & tests to reflect
1554 - added &clone_instance method which does a deep clone
1555 of the instance structure created by &construct_instance
1556 - added docs & tests for this
1557 - added Clone as a dependency
1558 - added &new_object and &clone_object convience methods to
1559 return blessed new or cloned instances
1560 - they handle Class::MOP::Class singletons correctly too
1561 - added docs & tests for this
1562 - cleaned up the &constuct_class_instance so that it behaves
1563 more like &construct_instance (and managed the singletons too)
1564 - added the &check_metaclass_compatibility method to make sure
1565 that metaclasses are upward and downward compatible.
1566 - added tests and docs for this
1569 - adjusting code to use the &Class::MOP::Class::meta
1571 - adjusting code to use the metaclass pragma
1573 0.05 Sat Feb. 4, 2006
1575 - added the &attribute_metaclass and &method_metaclass
1576 attributes which contain a metaclass name to use for
1577 attributes/methods respectively
1580 - bootstrap additional attributes for Class::MOP::Class
1583 - adjusted the example code and tests to use the new
1584 &attribute_metaclass feature of Class::MOP::Class
1585 - added new example:
1588 0.04 Fri Feb. 3, 2006
1590 - some documentation suggestions from #perl6
1592 * Class::MOP::Attribute
1593 - improved error messages

1608 - refactored the InsideOut example to take advantage
1609 of the Class::MOP::Attribute refactoring
1610 - changed example files to .pod files and hide thier
1611 package names from PAUSE (I don't want to own these
1612 namespaces really, they are just examples)
1614 0.02 Thurs Feb. 2, 2006
1615 - moving examples from t/lib/* to examples/*
1616 - adding POD documentation to the examples
