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)
18 0.92_01 Thu, Sep 10, 2009
20 - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
23 - Make sure XS code handles magical scalars correctly. (Goro Fuji)
26 - Documented the immutable_options method, which is useful if you need
27 to make a class mutable temporarily, and then nede to restore
28 immutability. (Dave Rolsky)
31 - Deprecated features have been moved to their own module,
32 Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)
37 - Move get_method_map and its various scaffolding into Package. (hdp)
40 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
41 the first argument, rather than just a coderef. (doy)
43 * Class::MOP::Attribute
45 - Allow attribute names to be false (while still requiring them to be
49 * Class::MOP::Method::Wrapped
50 - Fixing variable usage issues with the patch from previous
51 version, not properly using lexicals in the for
55 Japan Perl Association has sponsored Goro Fuji to improve startup
56 performance of Class::MOP and Moose. These enhancements may break
57 backwards compatibility if you're doing (or using) complex
58 metaprogramming, so, as always, test your code!
59 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
63 - Anonymous classes were not completely destroyed when they went
64 out of scope, leading to a memory leak. RT #47480. (Goro
68 - The get_method, has_method, and add_method methods no longer
69 use get_method_map. Method objects are instantiated
70 lazily. This significantly improves Class::MOP's load
74 - Inline fewer metaclass-level constructors since the ones we
75 have are perfectly fine. This reduces the number of string
78 * Class::MOP::Method::Wrapped
79 - If a method modifier set $_, this caused the modifier to blow
80 up, because of some weird internals. (Jeremy Stashewsky)
84 * Class::MOP::Class::Immutable::Trait
85 - Made the Trait act like a role with a bunch of "around"
86 modifiers, rather than sticking it in the inheritance
87 hierarchy. This fixes various problems that caused with
88 metaclass compatibility, which broke Fey::ORM.
91 - Allow a blessed code reference as the method body. Fixes a
92 problem interaction with MooseX::Types. (ash)
94 * Class::MOP::Instance
95 - add inline version of rebless_instance_structure. (doy)
96 - change inline_slot_access to use single quotes (gphat)
98 0.88 Tue, Jun 23, 2009
100 - Moved the __INSTANCE__ parameter to _construct_instance from
102 - Fixed some issues involving metaclasses of metaclasses and
105 0.87 Sun, Jun 21, 2009
107 - Made sure to always local-ize $@ and $SIG{__DIE__} before
108 calling an eval. Fixes RT #45973.
111 - Synced docs about immutability with the current reality (which
112 changed back in 0.82_01)
113 - Removed the immutable_transformer method, which had been
114 returning undef since 0.82_01 anyway.
117 - Got rid of tests which needed Moose and improved testing of
118 constructor/destructor inlining warnings. Fixes RT #47119.
120 0.86 Tue, Jun 16, 2009
122 - If you redefined a subroutine at runtime and then wrapped it
123 with a method modifier, the modifier could in some cases wrap
124 the original version of the subroutine. Fixes RT #46957.
127 - make_immutable issues a warning instead of overriding an
128 existing DESTROY method (Dylan William Hardison). Fixes RT
131 0.85 Sat, Jun 6, 2009
132 * Class::MOP::Attribute
133 - Allow default values to be Class::MOP::Methods. (Florian
135 - Test the above. (Rhesa Rozendaal)
136 - Tweak original commit so the intent matches the accepted
137 behavior (Nicholas Perez)
140 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
143 - Add direct_subclasses method (Sartak)
144 - Tests for subclasses and direct_subclasses (Sartak)
145 - subname is no longer used unconditionally in add_method, but
146 only if the code reference's name is '__ANON__' (nothingmuch)
147 - Add a hook for _superclasses_updated (Sartak)
150 - Remove long, old warning about possibly outdated modules
153 0.84 Tue, May 12, 2009
155 - Depend on Text::Exception 0.27 to avoid failing tests ond old
159 - Made is_class_loaded a little stricter. It was reporting that
160 a class was loaded if it merely had an @ISA variable in its
161 stash. Now it checks that the @ISA var has elements in it.
162 - Deprecate in_global_destruction and subname re-exporting
166 - Explicitly use Devel::GlobalDestruction and Sub::Name
169 * Class::MOP::Package
170 - Disable prototype mismatch warnings for add_package_symbol.
173 - Add test for finding methods from $meta->name->meta before immutable,
176 0.83 Mon, April 27, 2009
178 - Fix segfault when calling get_method_map on a metaclass for an empty
181 0.82_02 Fri, April 24, 2009
182 * Class::MOP::Method::Inlined
183 - Don't inline if the expected method is not defined at all (happens with
184 e.g. Moose::Object::_new is the expected method due to an overridden
187 - Some tests were trying to load Class::MOP::Immutable, which
188 was removed in 0.82_01.
190 0.82_01 Thu, April 23, 2009
191 * Class::MOP::Immutable (and others)
192 - Refactor the immutability system to use a pre-defined class
193 for the immutable metaclass of Class::MOP::Class::Immutable::$class
194 - Rather than generating methods into this class every time, use
195 a Trait (basic mixin) to supply the cached methods
196 - Remove the hack that returns the mutable metaclass for
197 metacircularity in order to provide consistent meta-metaclasses
198 for the Moose compatibility handling code
199 (mst broke it, nothingmuch fixed it)
201 0.82 Mon, April 20, 2009
203 - The deprecation wrappers for some renamed methods were not
204 passing arguments to the new method. (nothingmuch)
206 * Class::MOP::Immutable
207 - Warn during immutablization if the local class provides its own
208 constructor, to parallel the warning in Moose when a superclass
209 provides its own constructor (doy)
211 0.81 Tue, April 7, 2009
214 * Class::MOP::Instance
215 * Class::MOP::Attribute
216 * Class::MOP::Method::Accessor
217 * Class::MOP::Method::Constructor
218 - Include stack traces in the deprecation warnings introduced in
219 0.80_01. (Florian Ragwitz)
222 - Avoid c compiler warnings by declaring some unused function
223 arguments. (Florian Ragwitz)
225 0.80_01 Sun, April 5, 2009
227 - Make sure to preserve any compiler flags already defined in
228 Config.pm. Patch by Vincent Pit. RT #44739.
230 * Many methods have been renamed with a leading underscore, and a
231 few have been deprecated entirely. The methods with a leading
232 underscore are consider "internals only". People writing
233 subclasses or extensions to Class::MOP should feel free to
234 override them, but they are not for "public" use.
237 - construct_class_instance => _construct_class_instance (use new_object)
238 - construct_instance => _construct_instance (use new_object)
239 - check_metaclass_compatibility => _check_metaclass_compatibility
240 - create_meta_instance => _create_meta_instance (use get_meta_instance)
241 - clone_instance => _clone_instance (use clone_object)
242 - compute_all_applicable_methods is deprecated, use get_all_methods
243 - compute_all_applicable_attributes is deprecated, use get_all_attributes
245 - Class::MOP::Instance
246 - bless_instance_structure is deprecated and will be removed
250 - create has been renamed to _instantiate_module. This method
251 does not construct an object, it evals some code that
252 creates the relevant package in Perl's symbol table.
254 - Class::MOP::Method::Accessor
255 - initialize_body => _initialize_body (this is always called
256 when an object is constructed)
257 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
259 - Class::MOP::Method::Constructor
260 - initialize_body => _initialize_body (this is always called
261 when an object is constructed)
262 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
263 - attributes => _attributes
264 - meta_instance => _meta_instance
266 0.80 Wed, April 1, 2009
268 - Call user_class->meta in fewer places, with the eventual goal
269 of allowing the user to rename or exclude ->meta
270 altogether. Instead uses Class::MOP::class_of. (Sartak)
273 - New class_of function that should be used to retrieve a
274 metaclass. This is unlike get_metaclass_by_name in that it
275 accepts instances, not just class names. (Sartak)
278 - load_first_existing_class didn't actually load the first
279 existing class; instead, it loaded the first existing and
280 compiling class. It now throws an error if a class exists (in
281 @INC) but fails to compile. (hdp)
285 - we had some semi-buggy code that purported to provide a
286 HAS_ISAREV based on whether mro had get_isarev (due to an
287 oversight, it always returned 1). Since mro and MRO::Compat
288 have always had get_isarev, HAS_ISAREV was pointless. This
289 insight simplified the subclasses method by deleting the
290 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
292 0.79 Fri, March 29, 2009
293 * No changes from 0.78_02.
295 0.78_02 Thu, March 26, 2009
297 * Class::MOP::Immutable
298 - A big backwards-incompatible refactoring of the Immutable API,
299 and the make_immutable/make_mutable pieces of the Class
300 API. The core __PACKAGE__->meta->make_immutable API remains
301 the same, however, so this should only affect the most
305 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
306 has been fixed to be backwards compatible with 5.8.x.
309 - Add a hook for rebless_instance_away (Sartak)
310 - Use blessed instead of ref to get an instance's class name
311 in rebless_instance. (Sartak)
313 0.78_01 Wed, March 18, 2009
315 - Revised and reorganized all of the API documentation. All
316 classes now have (more or less) complete API documentation.
319 * Class::MOP::Instance
320 - Reblessing into a package that supports overloading wasn't
321 properly adding overload magic to the object due to a bug
322 in (at least) 5.8.8. We now use $_[1] directly which seems
323 to set the magic properly. (Sartak)
325 * Class::MOP::Attribute
326 - The process_accessors method is now private. A public alias
327 exists (and will stick around for a few releases), but it
328 warns that calling the public method is deprecated.
330 * Class::MOP::Method::Generated
331 - Removed the new and _new methods, since this is an abstract
332 base class, and all existing subclasses implement their own
336 - Stop is_class_loaded from thinking a class is loaded if it
337 only has an empty GV (Florian Ragwitz).
338 - Add a test for this (Yappo).
339 - Refactor get_all_package_symbols to allow short-circuiting
341 - Use this in is_class_loaded (Florian Ragwitz).
342 - Stop segfaulting when trying to get the name from a sub that's
343 still being compiled (Florian Ragwitz).
344 - Add tests for this (Florian Ragwitz).
345 - Prefix all public symbols with "mop_" (Florian Ragwitz).
346 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
347 - Simplify creating simple xs reader methods (Florian Ragwitz).
348 - Make everything compile with c++ compilers (Florian Ragwitz).
349 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
352 - Remove optional test plans for tests depending on Sub::Name as
353 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
356 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
358 0.78 Mon, February 23, 2009
359 * No changes from 0.77_01
361 0.77_01 Sun, February 22, 2009
363 - This package now requires its XS components. Not using
364 Sub::Name lead to different behavior and bugginess in the pure
365 Perl version of the code. A Moose test would fail when run
366 against the pure Perl version of this code.
368 * Class::MOP::Instance
369 - The inline_* methods now quote attribute names themselves, and
370 don't expect to receive a quoted value.
373 0.77 Sat, February 14, 2009
375 - Avoid assertion errors on debugging perls in is_class_loaded
379 - Fixed various corner cases where is_class_loaded incorrectly
380 returned true for a class that wasn't really loaded. (Dave
384 - Add get_all_method_names (Sartak)
385 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
387 * Class::MOP::Package
388 - Disable deprecated get_all_package_symbols in list
389 context. (Florian Ragwitz)
392 - Make sure we generate a BSD-compatible Makefile (Florian
396 - The misspelled "check_metaclass_compatability" method we've
397 kept around for backwards compat_i_bility will be removed in a
398 near future release. You've been warned.
400 0.76 Thu, January 22, 2009
401 * Class::MOP::Method::Generated
402 - Added new private methods to support code generation, which
403 are being used by Moose and can be used by MooseX
405 - Generated methods are now generated with a #line directive
406 reflecting the source of the generated method. (nothingmuch)
409 - Clarified documentation of methods that return
410 Class::MOP::Method objects. (doy)
413 - Clarified documentation of the metaclass cache methods. (Sartak)
416 - Add test showing how the xs Class::MOP::is_class_loaded can
417 be made to operate differently to the pure perl version (t0m)
419 0.75 Wed, December 31, 2008
421 - A class that was made immutable and then mutable could end up
422 sharing an immutable transformer object
423 (Class::MOP::Immutable) with other classes, leading to all
424 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
426 0.74 Tue, December 25, 2008
428 - Add an xs implementation of Class::MOP::is_class_loaded (closes
429 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
430 - Changed internals to make prehashing of hash keys easier and less
431 error-prone. (Florian Ragwitz)
433 - Fix documentation to show that around modifiers happen on both
434 sides of the modified method. (Dave Rolsky)
436 0.73 Tue, December 16, 2008
438 - Don't use Perl_mro_meta_init. It's not part of the public perl
439 api. Fixes failures to build on Win32 (RT #41750). (Florian
441 * t/082_get_code_info.t
442 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
443 munger anonymous subs when under -d and so making the tests
444 succeed in that case.
446 0.72 Mon, December 8, 2008
447 * Class::MOP::Package
448 - Pass options to _new, so subclass' attributes can be
451 - In the docs, indicate that package_name and name are required
452 when calling ->wrap (Stefan O'Rear)
454 0.71_02 Fri, December 5, 2008
455 * Class::MOP::Immutable
456 - Added a new attribute, inlined_constructor, which is true if
457 the constructor was inlined.
458 * Class::MOP::Package
459 - Make get_all_package_symbols return a hash ref in scalar
460 context and deprecate calling it in list context with a
461 warning. (Florian Ragwitz)
463 - Various improvements and refactoring, making things more robust and
464 easier to maintain. (Florian Ragwitz)
466 0.71_01 Wed, December 3, 2008
468 - Add an "execute" method to invoke the body so
469 we can avoid using the coderef overload (Sartak)
470 * Class::MOP::Immutable
471 - When we memoize methods, get their results lazily
472 to remove some compile-time cost (Sartak)
473 - Small speedup from eliminating several method
476 - Some small internal tweaks to try to reduce the number of
477 times we call get_method_map when bootstrapping the MOP. This
478 might make loading Class::MOP (and Moose) a little
479 faster. (Dave Rolsky)
480 - Implemented an optional XS version of get_method_map. Mostly
481 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
482 help form Florian Ragwitz. (Dave Rolsky)
483 - Make the behaviour of of get_all_package_symbols (and
484 therefore get_method_map) consistent for stub methods. Report
485 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
487 0.71 Wed November 26, 2008
490 - Actual package creation has moved upward from
491 Class to Module so that Moose roles can share
494 0.70_01 Mon, November 19, 2008
496 - Fixes for failures with blead (Florian Ragwitz)
497 - Silenced compiler warnings (Florian Ragwitz)
499 0.70 Fri, November 14, 2008
501 - Fixed an odd corner case where the XS version of
502 get_all_package_symbols could cause a segfault. This only
503 happened with inlined constants in Perl 5.10.0 (Florian
506 0.69 Fri, November 7, 2008
507 * Class::MOP::Method::Wrapped
508 - Added introspection methods for method modifiers (Dave Rolsky)
511 0.68 Fri October 24, 2008
513 - Make load_class require by file name instead of module name.
514 This stops confusing error messages when loading '__PACKAGE__'.
516 - Add load_one_class_of function to enable you to load one of a
517 list of classes, rather than having to call load_class multiple
518 times in an eval. (t0m)
520 0.67 Tue October 14, 2008
522 - Call a method on the class after setting the superclass list
523 so that we can get Perl to detect cycles before MRO::Compat
524 spirals into an infinite loop (sartak)
525 - Reported by Schwern, [rt.cpan.org #39001]
526 - In create(), pass unused options on to initialize()
527 - added test for this
529 0.66 Sat September 20, 2008
530 !! This release has an incompatible change regarding !!
531 introspection of a class's method with Class::MOP::Class !!
534 - We (us maintainers) now run all tests with XS and then without
535 XS, which should help us catch skew between the XS/pure Perl
539 ! The alias_method method has been deprecated. It now simply
540 calls add_method instead. There is no distinction between
541 aliased methods and "real" methods.
543 This means that methods added via alias_method now show up as
544 part of the class's method list/map. This is a backwards
545 incompatible change, but seems unlikely to break any
546 code. Famous last words. (Dave Rolsky)
549 - Fixed the spelling of "compatibility", but we still have a
550 "check_metaclass_compatability" method for backwards
553 0.65 Mon September 1, 2008
554 For those not following the series of dev releases, the changes
555 from 0.64 from 0.65 can mostly be summed up as a lot performance
556 improvements by nothingmuch, including new optional XS versions of
557 some methods. Also, Class::MOP now works _without_ any XS modules,
558 for sad systems without a compiler.
561 - Added name and package_name XS accessors, and make sure all
562 the XS and Perl versions work the same way. (Dave Rolsky)
565 - The XS versions of various methods just returned undef when
566 called class methods, rather than dying like the pure Perl
567 versions. (Dave Rolsky)
569 0.64_07 Fri August 29, 2008
571 - Silenced warnings that managed to break Moose tests when XS
572 was loaded. (Dave Rolsky)
573 - Some XS versions of methods were ignored because of typos in
574 MOP.xs. (Dave Rolsky)
576 0.64_06 Mon August 25, 2008
577 * Class::MOP (MOP.xs)
578 - Another MS VC++ fix, cannot declare a variable in the middle
579 of a scope (Taro Nishino).
581 0.64_05 Sun August 24, 2008
583 - None of the dev releases actually loaded the XS properly, but
584 we silently fell back to the pure Perl version of the
587 * Class::MOP (MOP.xs)
588 - Replaced some code that used functions not available on Visual
589 C++ with some Perl XS API bits (Dave Rolsky).
591 0.64_04 Sat August 23, 2008
593 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
595 * pod.t and pod_coveraget.t
596 - These are no longer shipped with the tarball because of bogus
597 failures from CPAN testers. (Dave Rolsky)
599 0.64_03 Thu August 21, 2008
600 * Class::MOP::Package
601 - Some (legit) code was misparsed by earlier 5.8.x
602 releases. (nothingmuch)
605 - Fix a constant in void context warning (nothingmuch)
607 0.64_02 Thu August 21, 2008
608 * Makefile.PL and Class::MOP
609 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
612 - Add missing prereqs that got lost in the switch away from
615 * Class::MOP::Instance
616 - New method - get_all_attributes (nothingmuch)
618 0.64_01 Wed August 20, 2008
620 - We now check to see if you have a compiler. If you don't, the
621 module installs without some XS bits, but will work the same
622 as with XS. This should make it easier to install on platforms
623 without a compiler (like Windows). (Dave Rolsky)
626 - Perl 6 style attribute naming replaced with sane style ('methods', not
627 '%!methods'). These changes should not impact any existing API uses.
631 - Quite a number of optimizations based on profiling, including
632 allowing constructors to take hash references instead of
633 hashes, duplicating some frequently used code in XS, and
634 making constructors immutable. These changes should not impact
635 any existing API uses. (nothingmuch)
638 - Constructors now respect the meta attributes of their subclasses,
639 facilitating MOP extensibility. More related changes will happen in the
640 next several releases. (nothingmuch)
643 - New method - get_all_methods, replaces the deprecated
644 compute_all_applicable_methods. get_all_attributes provided for
645 consistency (nothingmuch)
646 - New method - wrap_method was refactored out of get_method_map
648 - New API for meta instance invalidation - invalidate_meta_instance,
649 invalidate_meta_instances, add_dependent_meta_instance,
650 remove_dependent_meta_instance, called automatically when attribute
651 definitions change and allows notification of dependent subclasses.
654 0.64 Sun August 3, 2008
655 * Class::MOP::Immutable
656 - fixing subtle edge case in immutable when you
658 - clean up option processing (nothingmuch)
660 * Class::MOP::Instance
661 - inlined initialize slot didn't match
662 non-inlined (nothingmuch)
664 0.63 Mon July 7, 2008
666 - load_class will initialize a metaclass even if
667 the class is already loaded (sartak)
668 - load_class now returns the metaclass instance
669 instead of just 1 (sartak)
672 - better error messages (sartak and Dave Rolsky)
674 0.62 Wed June 18, 2008
675 - in is_class_loaded, recognize scalar references (as opposed to globs) in
676 the symbol table as methods (these are optimized constant subs)
678 0.61 Fri. June 13, 2008
679 - Okay, lets give this another try and see if PAUSE
680 recognizes it correct this time.
682 0.60 Thurs. Jun 12, 2008
683 - Fixed a version number issue by bumping all modules
686 0.59 Thurs. Jun 12, 2008
687 !! Several fixes resulting in yet another 25-30% speedup !!
690 - now stores the instance of the instance
691 metaclass to avoid needless recomputation
692 and deletes it when the cache is blown
693 - introduce methods to query Class::MOP::Class for
694 the options used to make it immutable as well as
695 the proper immutable transformer. (groditi)
697 * Class::MOP::Package
698 - {add, has, get, remove}_package_symbol all
699 now accept a HASH ref argument as well as the
700 string. All internal usages now use the HASH
704 - MOP.xs does sanity checks on the coderef
706 - is_class_loaded check now uses code that
707 was improved in Moose's ClassName type
709 - nonsensical (undef, empty, reference) class
710 names now throw a more direct error in
712 - tests for this and other aspects of
718 Class::MOP::Method::Wrapped
719 Class::MOP::Attribute
720 - switched usage of reftype to ref because
723 0.58 Thurs. May 29, 2008
724 (late night release engineering)--
726 - fixing the version is META.yml, no functional
727 changes in this release
729 0.57 Wed. May 28, 2008
730 !! Several speedups resulting in 20-25% speedups !!
731 || (thanks to konobi, groditi, mst & CataMoose) !!
734 - made get_method_map use list_all_package_symbols
735 instead of manually grabbing each symbol
736 - streamlining &initialize somewhat, since it gets
739 * Class::MOP::Package
740 - made {get, has}_package_symbol not call
742 - inlining a few calls to &name with
743 direct HASH access key access
744 - added get_all_package_symbols to fetch
745 a HASH of items based on a type filter
746 similar to list_all_package_symbols
747 - added tests for this
750 Class::MOP::Method::Constructor
751 Class::MOP::Method::Generated
752 Class::MOP::Method::Accessor
753 - added more descriptive error message to help
754 keep people from wasting time tracking an error
755 that is easily fixed by upgrading.
757 * Class::MOP::Immutable
758 - Don't inline a destructor unless the user actually
760 - added tests for this
762 0.56 Saturday, May 24, 2008
764 - we now get the &check_package_cache_flag
765 function from MRO::Compat
766 - All XS based functionality now has a
767 Pure Perl alternative
768 - the CLASS_MOP_NO_XS environment variable
769 can now be used to force non-XS versions
772 * Class::MOP::Attribute

779 * Class::MOP::Immutable
780 - added the ability to "wrap" methods when
781 making the class immutable
784 - now handling the edge case of ->meta->identifier
785 dying by wrapping add_package_symbol to specifically
786 allow for it to work.
787 - added tests for this
789 * Class::MOP::Attribute
791 Class::MOP::Immutable
792 - any time a method meta object is constructed
793 we make sure to pass the correct package and
794 method name information
797 Class::MOP::Method::Wrapped
798 Class::MOP::Method::Generated
799 Class::MOP::Method::Accessor
800 Class::MOP::Method::Consructor
801 - the &wrap constructor method now requires that a
802 'package_name' and 'name' attribute are passed. This
803 is to help support the no-XS version, and will
804 throw an error if these are not supplied.
805 - all these classes are now bootstrapped properly
806 and now store the package_name and name attributes
809 ~ Build.PL has been removed since the
810 Module::Install support has been removed
812 0.55 Mon. April 28, 2008
813 - All classes now have proper C3 MRO support
814 - added MRO::Compat as a dependency to allow
815 for the C3 MRO support to Just Work in all
819 - rebless_instance now returns the instance
820 it has just blessed, this is mostly to
822 - set the attr correctly in rebless_instance
823 when it has no init_arg
824 - tweaked &linear_isa and &class_precedence_list
825 to support c3 classes.
827 0.54 Fri. March, 14, 2008
830 - making sure that load_class never gets
831 passed a value from @_ or $_ to squash
832 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
835 - make_{immutable,mutable} now return 1
837 - improved error handling in ->create method
838 - rebless_instance now takes extra params which
839 will be used to populate values
840 - added tests for this
843 - localizing the Data::Dumper configurations so
844 that it does not pollute others (RT #33509)
850 Class::MOP::Attribute
851 - these classes no longer define their own ->meta,
852 but instead just inherit from Class::MOP::Object
854 * Class::MOP::Instance
855 Class::MOP::Immutable
856 - these classes now inherit from Class::MOP::Object
859 - fixed the filename length on several
860 test files so we install on VMS better
862 - fixed incorrect use of catdir when it
863 should be catfile (RT #32385)
865 0.53 Thurs. Feb. 14, 1008
866 ~~ several doc. fixes and updates ~~
869 Class::MOP::Method::Constructor

871 - making init_arg accept an undefined value
872 to indicate that no constructor args can
873 be passed (thanks to nothingmuch)
874 - added tests for this
875 - added attribute initializer attribute (rjbs)
878 - making this use the new init_arg => undef
879 feature instead of the silly hack from
880 before (thanks to nothingmuch)
882 0.52 Tues. Jan. 22, 2008
884 - fixed bug in rebless_instance
887 * Class::MOP::Method::Constructor
888 - removed assumptions about the existence of
891 0.51 Mon. Jan. 14, 2008
892 ~~~ some misc. doc. fixes ~~~
893 ~~ updated copyright dates ~~
896 - now sets the IS_RUNNING_ON_5_10
897 constant so that we can take advantage
898 of some of the nice bits of 5.10
901 - uses the IS_RUNNING_ON_5_10 flag to
902 optimize the &linearized_isa method
903 and avoid the hack/check for circular
904 inheritence in &class_precedence_list
905 - added rebless_instance method (Sartak)
906 - added tests for this
908 * Class::MOP::Immutable
909 - the immutable class now keeps track of
910 the transformer which immutablized it
912 * Class::MOP::Instance
913 - added rebless_instance_structure method (Sartak)
914 - added tests for this
916 0.50 Fri. Dec. 21, 2007

926 * Class::MOP::Attribute
929 0.49 Fri. Dec. 14, 2007
930 !! Class::MOP now loads 2 x faster !!
931 !! with XS speedups (thanks konobi) !!
934 - removed the dependency on B
935 - added two XS functions (thanks konobi)
936 - get_code_info($code) which replaces all
937 the B fiddling we were doing with
938 faster/leaner XS level fiddling
939 - check_package_cache_flag($pkg_name) which
940 returns the PL_sub_generation variable to
941 be used to help manage method caching.
944 In 5.10 or greater this will actually
945 use the mro::get_pkg_gen instead to give
946 even more accurate caching information.
947 blblack++ for that stuff :)
950 - added the &subclasses method (thanks rlb)
951 - added the update_package_cache_flag and
952 reset_package_cache_flag which help keep
953 track of when we need to re-fetch the
955 - Several small improvements to take advantage
956 of the new method map caching features
958 0.48 Mon. Nov. 26, 2007
959 * Class::MOP::Attribute
960 - fixed get_read/write_method to handle the

973 pruning duplicate classes (this will be even more
974 useful in the 5.10-compat version coming soon)
976 * Class::MOP::Attribute
977 - added the get_read_method_ref and get_write_method_ref
978 methods which allow you to retrieve a CODE ref which
979 can always be used to read or write an attribute.
981 0.45 Thurs. Nov. 13, 2007
982 * Class::MOP::Attribute
983 - Fix error message on confess (groditi)
985 0.44 Thurs. Nov. 13, 2007

1009 - removed the relevant attributes
1011 * Class::MOP::Method::Constructor
1012 - fixed the cached values we had to be more sane
1013 - made this a subclass of Class::MOP::Method::Generated
1014 - fixed generated constructor so it properly handles
1016 - added tests for this
1017 - added the option to allow for both inlined and
1018 non-inlined constructors.
1019 - Update inlined methods for builder and predicate changes (groditi)
1021 * Class::MOP::Method::Generated
1022 - added this class as an abstract base for the
1023 Class::MOP::Method::{Constructor,Accessor} classes
1024 - added tests for this

1037 - alter symbol table handling to deal with 5.8.x and 5.9.x
1040 - Get rid of the crappy workaround from 0.40/41
1042 0.41 Sun. July 15, 2007
1044 Arghh!!! My TODO test didn't work, so I handle
1045 it manually now so that people can use this
1046 with 5.9.5/bleadperl without issue.
1048 0.40 Tues, July 3, 2007
1050 ~ marked a test in 003_methods.t as TODO
1051 for perl 5.9.5 (this test is irrelvant to
1052 the module functioning on 5.9.5 for the most
1055 0.39 Mon. June 18, 2007
1056 * Class::MOP::Immutable
1057 - added make_metaclass_mutable + docs (groditi)
1058 - removed unused variable
1059 - added create_immutable_transformer
1060 necessary for sane overloading of immutable behavior
1061 - tests for this (groditi)
1064 - Immutability can now be undone,
1065 added make_mutable + tests + docs (groditi)
1066 - Massive changes to the way Immutable is done
1067 for details see comments next to make_immutable
1068 This fixes a bug where custom metaclasses broke
1069 when made immutable. We are now keeping one immutable
1070 metaclass instance per metaclass instead of just one
1071 to prevent isa hierarchy corruption. Memory use will go
1072 up, but I suspect it will be neglible.
1073 - New tests added for this behavior. (groditi)
1075 0.38 Thurs. May 31, 2007
1076 ~~ More documentation updates ~~
1078 * Class::MOP::Package
1079 - we now deal with stub methods properly

1083 * Class::MOP::Attribute
1084 - added get_read_method and get_write_method
1085 thanks to groditi for this code, tests
1087 - added tests and POD for this
1090 - fixed RT issue #27329, clone object now
1091 handles undef values correctly.
1092 - added tests for this
1093 - Corrected anon-class handling so that they
1094 will not get reaped when instances still
1095 exist which need to reference them. This is
1096 the correct behavior, hopefully this is an
1097 obscure enough feature that there are not too
1098 many work arounds out in the wild.
1099 - added tests for this by groditi
1100 - updated docs to explain this
1103 - load custom metaclasses automatically (thanks groditi)
1104 - added tests for this behavior
1106 0.37 Sat. March 10, 2007

1115 avoid setting off bool-overloads (found by Carl Franks)
1119 - bad name in a test, causing meaningless failuress.
1124 ~~ GLOBAL CHANGES ~~
1125 - All attribute names are now consistent and follow Perl 6
1126 style (prefixed with the sigil, and ! as the twigil for
1127 private attrs). This should not affect any code, unless
1128 you broke encapsulation, in which case, it is your problem
1131 !! Class::MOP::Class::Immutable has been removed
1133 * Class::MOP::Method::Constructor
1134 - this has been moved out of Class::MOP::Class::Immutable
1135 and is a proper subclass of Class::MOP::Method now.
1138 - this module now uses Class::MOP::Immutable for the
1139 immutable transformation instead of
1140 Class::MOP::Class::Immutable.
1142 + Class::MOP::Immutable
1143 - this module now controls the transformation from a mutable
1144 to an immutable version of the class. Docs for this will
1145 be coming eventually.
1148 0.36 Sun. Nov. 5, 2006
1150 - added a few 'no warnings' lines to keep annoying
1151 (and meaningless) warnings from chirping during
1155 - some more bootstrapping is now done on the new
1158 * Class::MOP::Class::Immutable
1160 - constructor generation is now handled by
1161 the Class::MOP::Method::Constructor class
1163 * Class::MOP::Method::Constructor
1164 - created this to handle constructor generation
1165 in Class::MOP::Class::Immutable
1167 * Class::MOP::Attribute
1169 - attributes now delegate to the
1170 Class::MOP::Method::Accessor to generate
1173 * Class::MOP::Method::Accessor
1174 - all accessor generation functions from
1175 Class::MOP::Attribute have been moved here
1177 0.35 Sat. Sept. 30, 2006

1180 - initial prototype of a class browser, more
1181 on this to come. Comments and patches are
1185 - All Class::MOP::* accessors are no longer
1186 re-generated in the bootstrap, instead
1187 they are aliased from the originals
1188 - fixed tests to reflect
1189 - added Class::MOP::Method (and its subclasses)
1191 - adjusted tests for this
1192 - added the Class::MOP::Instance attributes

1199 - adjusted tests to compensate
1200 - adjusted docs for this
1203 - changed how methods are dealt with to
1204 encapsulate most of the work into the
1205 &get_method_map method
1206 - made several adjustments for the change
1207 in Class::MOP::Method
1208 - &add_attribute now checks if you are adding
1209 a duplicate name, and properly removes the
1210 old one before installing the new one
1211 - added tests for this
1212 - adjusted docs for this
1214 * Class::MOP::Class::Immutable
1215 - added caching of &get_method_map
1216 - fixed issue with &get_package_symbol
1217 - cleaned up the methods that die (patch by David Wheeler)

1221 &list_all_package_symbols
1223 0.34 Sat. Aug. 26, 2006
1225 - added the %:methods attribute, which like
1226 the $:version and such just actually goes
1227 to the symbol table to get it's stuff.
1228 However, it makes the MOP more complete.
1230 - The &create method now requires that all
1231 but the package name now is passed in as
1232 named parameters. See docs for more info.
1233 - updated docs and tests for this
1235 * Class::MOP::Object
1236 - added &dump method to easily Data::Dumper

1258 are no longer allowed for defaults
1259 - added tests for this
1261 * Class::MOP::Package
1262 - fixed an issue with perl 5.8.1 and how it deals
1263 with symbol tables. The namespace hash is now
1264 always reloaded from the symbol table.
1266 ~ lots of misc. documentation cleanup
1268 0.32 Sat. Aug. 12, 2006
1269 + added Class::MOP::Object so that the
1270 metamodel is more complete (and closer
1271 to what Perl 6 will probably be).

1275 the primary gateway between the metaclass
1276 and the Perl 5 symbol table
1277 - added many tests for this
1278 - this class is now a subclass of
1280 - added some tests to reflect this

1284 use Class::MOP::Package methods instead
1286 * Class::MOP::Module
1287 - adding the $:version attribute in the bootstrap
1288 so that Module has a version as an attribute
1289 - see comment in Class::MOP for details
1290 - added the $:authority attribute to this module
1291 as well as an &identifier method, to bring us
1292 ever closer to Perl 6 goodness
1293 - I have added $AUTHORITY to all the modules
1294 - added tests for this

1313 - added &set_value and &get_value for getting
1314 the value of the attribute for a particular
1317 0.30 Wed. July 5, 2006
1318 ---------------------------------------
1319 This is the first version of Class::MOP
1320 to introduce the immutable features which
1321 will be used for optimizating the MOP.
1322 This support should still be considered
1323 experimental, but moving towards stability.
1324 ---------------------------------------
1326 * Created Class::MOP::Class::Immutable
1328 * Created the Class::MOP::Package and
1329 Class::MOP::Module classes to more
1330 closely conform to Perl 6's meta-model
1333 - now inherits from Class::MOP::Module
1334 - several methods moved to ::Module and
1335 ::Package and now inherited
1336 - added tests for this
1338 * Class::MOP::Instance
1339 - added an is_inlinable method to allow other
1340 classes to check before they attempt to optimize.
1341 - added an inline_create_instance to inline
1342 instance creation (of course)
1345 - the Class::MOP::Class::*_package_variable
1346 methods are all now methods of Class::MOP::Package
1347 and called *_package_symbol instead. This is
1348 because they are now more general purpose symbol
1349 table manipulation methods.
1351 0.29_02 Thurs. June 22, 2006
1352 ++ DEVELOPER RELEASE ++
1354 - small change in &create so that it behaves

1406 - added tests for this
1407 - added get_all_metaclasses, get_all_metaclass_names
1408 and get_all_metaclass_instances method to allow
1409 access to all the cached metaclass objects.
1410 - attribute slot initialization is now the responsibility
1411 of the attribute itself, and construct_instance now
1412 delegates appropriately
1414 * Class::MOP::Attribute
1415 - attribute slot initialization is now the responsibility
1416 of the attribute itself, so we added a method for it
1417 called initialize_instance_slot

1434 - read-only accessors ('reader') will now die if
1435 passed more than one argument (attempting to write

1438 - adjusted all /example files to comply
1440 0.22 Mon. March 20, 2006

1444 - added test case for this
1446 0.21 Wed. March 15, 2006
1448 - fixed issue where metaclasses are reaped from

1454 we no longer to deep-cloning by default.
1456 * Class::MOP::Method
1457 - added &package_name, &name and
1458 &fully_qualified_name methods, some of
1459 which were formerly private subs in
1462 * Class::MOP::Method::Wrapped
1463 - allows for a method to be wrapped with
1464 before, after and around modifiers
1465 - added tests and docs for this feature
1468 - improved &get_package_symbol
1469 - &version and &superclasses now use it
1470 - methods are now blessed into Class::MOP::Method
1472 - added methods to install CLOS-style method modifiers
1473 - &add_before_method_modifier
1474 - &add_after_method_modifier
1475 - &add_around_method_modifier
1476 - added tests and docs for these
1477 - added &find_next_method_by_name which finds the
1478 equivalent of SUPER::method_name
1480 0.12 Thurs. Feb 23, 2006
1481 - reduced the dependency on B, no need to always
1485 - added docs to the C3 method dispatch order test
1486 - fixed missing Algorithm::C3 dependency by making
1487 the test skip if it is not installed
1489 0.11 Mon Feb. 20, 2006
1491 - added example of changing method dispatch order to C3
1494 - changed how clone_instance behaves, it now only does a
1495 shallow clone (see docs for more details)
1496 - added docs and tests
1498 0.10 Tues Feb. 14, 2006
1499 ** This release was mostly about writing more tests and
1500 cleaning out old and dusty code, the MOP should now
1501 be considered "ready to use".
1503 - adding more tests to get coverage up a little higher,
1504 mostly testing errors and edge cases.
1505 - test coverage is now at 99%
1508 - no longer optionally exports to UNIVERSAL::meta or
1509 creates a custom metaclass generator, use the
1510 metaclass pragma instead.
1513 - fixed a number of minor issues which came up in the
1514 error/edge-case tests
1516 * Class::MOP::Attribute
1517 - fixed a number of minor issues which came up in the
1518 error/edge-case tests
1521 - fixing the AttributesWithHistory example, it was broken.
1523 0.06 Thurs Feb. 9, 2006
1525 - adding new metaclass pragma to make setting up the
1526 metaclass a little more straightforward
1529 - clean up bootstrapping to include more complete
1530 attribute definitions for Class::MOP::Class and
1531 Class::MOP::Attribute (accessors, readers, writers,
1532 etc.) ... it is redundant, but is useful meta-info
1536 - fixing minor meta-circularity issue with &meta, it
1537 is now more useful for subclasses
1538 - added &get_attribute_map as an accessor for the
1539 hash of attribute meta objects
1540 - &compute_all_applicable_attributes now just returns
1541 the attribute meta-object, rather than the HASH ref
1542 since all the same info can be gotten from the
1543 attribute meta-object itself
1544 - updated docs & tests to reflect
1545 - added &clone_instance method which does a deep clone
1546 of the instance structure created by &construct_instance
1547 - added docs & tests for this
1548 - added Clone as a dependency
1549 - added &new_object and &clone_object convience methods to
1550 return blessed new or cloned instances
1551 - they handle Class::MOP::Class singletons correctly too
1552 - added docs & tests for this
1553 - cleaned up the &constuct_class_instance so that it behaves
1554 more like &construct_instance (and managed the singletons too)
1555 - added the &check_metaclass_compatibility method to make sure
1556 that metaclasses are upward and downward compatible.
1557 - added tests and docs for this
1560 - adjusting code to use the &Class::MOP::Class::meta
1562 - adjusting code to use the metaclass pragma
1564 0.05 Sat Feb. 4, 2006
1566 - added the &attribute_metaclass and &method_metaclass
1567 attributes which contain a metaclass name to use for
1568 attributes/methods respectively
1571 - bootstrap additional attributes for Class::MOP::Class
1574 - adjusted the example code and tests to use the new
1575 &attribute_metaclass feature of Class::MOP::Class
1576 - added new example:
1579 0.04 Fri Feb. 3, 2006
1581 - some documentation suggestions from #perl6
1583 * Class::MOP::Attribute
1584 - improved error messages

1599 - refactored the InsideOut example to take advantage
1600 of the Class::MOP::Attribute refactoring
1601 - changed example files to .pod files and hide thier
1602 package names from PAUSE (I don't want to own these
1603 namespaces really, they are just examples)
1605 0.02 Thurs Feb. 2, 2006
1606 - moving examples from t/lib/* to examples/*
1607 - adding POD documentation to the examples
