1 Revision history for Perl extension Class-MOP.
4 - Make is_class_loaded without any arguments fail loudly
9 - Any method which takes a method name as an argument now allows names
10 which are false (like "0"), but the name must be defined and not be an
11 empty string. (Dave Rolsky)
14 - Deprecated get_attribute_map as a public method. You can use a
15 combination of get_attribute_list and get_attribute instead. (Dave
18 0.94 Tue, Sep 22, 2009
19 * Class::MOP::Attribute
20 - Introduce set_raw_value and get_raw_value, side effect free variants
21 of {get,set}_value. These don't do anything useful in Class::MOP but
22 have different behavior that set_value and get_value for Moose
23 attributes. (nothingmuch)
25 0.93 Tue, Sep 15, 2009
27 - The load_class function just returns true, since it's return value was
28 confusing (either a metaclass object or a class name). It either loads
29 a class or dies trying. In the future, this may change to not return
30 anything, since there's no point in checking its return
31 value. Addresses RT #45883. (Dave Rolsky)
33 * Class::MOP::Class::Trait::Immutable
34 - When throwing an error because of an immutable method, include that
35 method's name. Addresses RT #49680. (Shawn M Moore)
38 - Adding the same sub reference to multiple packages failed to update
39 the method map properly. RT #48985. Reported by Paul Mooney. (Dave
41 - The get_method_map method is now private (and called as
42 _full_method_map or _method_map). The public version is available as a
43 deprecated method. (Dave Rolsky)
45 0.92_01 Thu, Sep 10, 2009
47 - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
50 - Make sure XS code handles magical scalars correctly. (Goro Fuji)
53 - Documented the immutable_options method, which is useful if you need
54 to make a class mutable temporarily, and then nede to restore
55 immutability. (Dave Rolsky)
58 - Deprecated features have been moved to their own module,
59 Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)
64 - Move get_method_map and its various scaffolding into Package. (hdp)
67 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
68 the first argument, rather than just a coderef. (doy)
70 * Class::MOP::Attribute
72 - Allow attribute names to be false (while still requiring them to be
76 * Class::MOP::Method::Wrapped
77 - Fixing variable usage issues with the patch from previous
78 version, not properly using lexicals in the for
82 Japan Perl Association has sponsored Goro Fuji to improve startup
83 performance of Class::MOP and Moose. These enhancements may break
84 backwards compatibility if you're doing (or using) complex
85 metaprogramming, so, as always, test your code!
86 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
90 - Anonymous classes were not completely destroyed when they went
91 out of scope, leading to a memory leak. RT #47480. (Goro
95 - The get_method, has_method, and add_method methods no longer
96 use get_method_map. Method objects are instantiated
97 lazily. This significantly improves Class::MOP's load
101 - Inline fewer metaclass-level constructors since the ones we
102 have are perfectly fine. This reduces the number of string
105 * Class::MOP::Method::Wrapped
106 - If a method modifier set $_, this caused the modifier to blow
107 up, because of some weird internals. (Jeremy Stashewsky)
111 * Class::MOP::Class::Immutable::Trait
112 - Made the Trait act like a role with a bunch of "around"
113 modifiers, rather than sticking it in the inheritance
114 hierarchy. This fixes various problems that caused with
115 metaclass compatibility, which broke Fey::ORM.
118 - Allow a blessed code reference as the method body. Fixes a
119 problem interaction with MooseX::Types. (ash)
121 * Class::MOP::Instance
122 - add inline version of rebless_instance_structure. (doy)
123 - change inline_slot_access to use single quotes (gphat)
125 0.88 Tue, Jun 23, 2009
127 - Moved the __INSTANCE__ parameter to _construct_instance from
129 - Fixed some issues involving metaclasses of metaclasses and
132 0.87 Sun, Jun 21, 2009
134 - Made sure to always local-ize $@ and $SIG{__DIE__} before
135 calling an eval. Fixes RT #45973.
138 - Synced docs about immutability with the current reality (which
139 changed back in 0.82_01)
140 - Removed the immutable_transformer method, which had been
141 returning undef since 0.82_01 anyway.
144 - Got rid of tests which needed Moose and improved testing of
145 constructor/destructor inlining warnings. Fixes RT #47119.
147 0.86 Tue, Jun 16, 2009
149 - If you redefined a subroutine at runtime and then wrapped it
150 with a method modifier, the modifier could in some cases wrap
151 the original version of the subroutine. Fixes RT #46957.
154 - make_immutable issues a warning instead of overriding an
155 existing DESTROY method (Dylan William Hardison). Fixes RT
158 0.85 Sat, Jun 6, 2009
159 * Class::MOP::Attribute
160 - Allow default values to be Class::MOP::Methods. (Florian
162 - Test the above. (Rhesa Rozendaal)
163 - Tweak original commit so the intent matches the accepted
164 behavior (Nicholas Perez)
167 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
170 - Add direct_subclasses method (Sartak)
171 - Tests for subclasses and direct_subclasses (Sartak)
172 - subname is no longer used unconditionally in add_method, but
173 only if the code reference's name is '__ANON__' (nothingmuch)
174 - Add a hook for _superclasses_updated (Sartak)
177 - Remove long, old warning about possibly outdated modules
180 0.84 Tue, May 12, 2009
182 - Depend on Text::Exception 0.27 to avoid failing tests ond old
186 - Made is_class_loaded a little stricter. It was reporting that
187 a class was loaded if it merely had an @ISA variable in its
188 stash. Now it checks that the @ISA var has elements in it.
189 - Deprecate in_global_destruction and subname re-exporting
193 - Explicitly use Devel::GlobalDestruction and Sub::Name
196 * Class::MOP::Package
197 - Disable prototype mismatch warnings for add_package_symbol.
200 - Add test for finding methods from $meta->name->meta before immutable,
203 0.83 Mon, April 27, 2009
205 - Fix segfault when calling get_method_map on a metaclass for an empty
208 0.82_02 Fri, April 24, 2009
209 * Class::MOP::Method::Inlined
210 - Don't inline if the expected method is not defined at all (happens with
211 e.g. Moose::Object::_new is the expected method due to an overridden
214 - Some tests were trying to load Class::MOP::Immutable, which
215 was removed in 0.82_01.
217 0.82_01 Thu, April 23, 2009
218 * Class::MOP::Immutable (and others)
219 - Refactor the immutability system to use a pre-defined class
220 for the immutable metaclass of Class::MOP::Class::Immutable::$class
221 - Rather than generating methods into this class every time, use
222 a Trait (basic mixin) to supply the cached methods
223 - Remove the hack that returns the mutable metaclass for
224 metacircularity in order to provide consistent meta-metaclasses
225 for the Moose compatibility handling code
226 (mst broke it, nothingmuch fixed it)
228 0.82 Mon, April 20, 2009
230 - The deprecation wrappers for some renamed methods were not
231 passing arguments to the new method. (nothingmuch)
233 * Class::MOP::Immutable
234 - Warn during immutablization if the local class provides its own
235 constructor, to parallel the warning in Moose when a superclass
236 provides its own constructor (doy)
238 0.81 Tue, April 7, 2009
241 * Class::MOP::Instance
242 * Class::MOP::Attribute
243 * Class::MOP::Method::Accessor
244 * Class::MOP::Method::Constructor
245 - Include stack traces in the deprecation warnings introduced in
246 0.80_01. (Florian Ragwitz)
249 - Avoid c compiler warnings by declaring some unused function
250 arguments. (Florian Ragwitz)
252 0.80_01 Sun, April 5, 2009
254 - Make sure to preserve any compiler flags already defined in
255 Config.pm. Patch by Vincent Pit. RT #44739.
257 * Many methods have been renamed with a leading underscore, and a
258 few have been deprecated entirely. The methods with a leading
259 underscore are considered "internals only". People writing
260 subclasses or extensions to Class::MOP should feel free to
261 override them, but they are not for "public" use.
264 - construct_class_instance => _construct_class_instance (use new_object)
265 - construct_instance => _construct_instance (use new_object)
266 - check_metaclass_compatibility => _check_metaclass_compatibility
267 - create_meta_instance => _create_meta_instance (use get_meta_instance)
268 - clone_instance => _clone_instance (use clone_object)
269 - compute_all_applicable_methods is deprecated, use get_all_methods
270 - compute_all_applicable_attributes is deprecated, use get_all_attributes
272 - Class::MOP::Instance
273 - bless_instance_structure is deprecated and will be removed
277 - create has been renamed to _instantiate_module. This method
278 does not construct an object, it evals some code that
279 creates the relevant package in Perl's symbol table.
281 - Class::MOP::Method::Accessor
282 - initialize_body => _initialize_body (this is always called
283 when an object is constructed)
284 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
286 - Class::MOP::Method::Constructor
287 - initialize_body => _initialize_body (this is always called
288 when an object is constructed)
289 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
290 - attributes => _attributes
291 - meta_instance => _meta_instance
293 0.80 Wed, April 1, 2009
295 - Call user_class->meta in fewer places, with the eventual goal
296 of allowing the user to rename or exclude ->meta
297 altogether. Instead uses Class::MOP::class_of. (Sartak)
300 - New class_of function that should be used to retrieve a
301 metaclass. This is unlike get_metaclass_by_name in that it
302 accepts instances, not just class names. (Sartak)
305 - load_first_existing_class didn't actually load the first
306 existing class; instead, it loaded the first existing and
307 compiling class. It now throws an error if a class exists (in
308 @INC) but fails to compile. (hdp)
312 - we had some semi-buggy code that purported to provide a
313 HAS_ISAREV based on whether mro had get_isarev (due to an
314 oversight, it always returned 1). Since mro and MRO::Compat
315 have always had get_isarev, HAS_ISAREV was pointless. This
316 insight simplified the subclasses method by deleting the
317 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
319 0.79 Fri, March 29, 2009
320 * No changes from 0.78_02.
322 0.78_02 Thu, March 26, 2009
324 * Class::MOP::Immutable
325 - A big backwards-incompatible refactoring of the Immutable API,
326 and the make_immutable/make_mutable pieces of the Class
327 API. The core __PACKAGE__->meta->make_immutable API remains
328 the same, however, so this should only affect the most
332 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
333 has been fixed to be backwards compatible with 5.8.x.
336 - Add a hook for rebless_instance_away (Sartak)
337 - Use blessed instead of ref to get an instance's class name
338 in rebless_instance. (Sartak)
340 0.78_01 Wed, March 18, 2009
342 - Revised and reorganized all of the API documentation. All
343 classes now have (more or less) complete API documentation.
346 * Class::MOP::Instance
347 - Reblessing into a package that supports overloading wasn't
348 properly adding overload magic to the object due to a bug
349 in (at least) 5.8.8. We now use $_[1] directly which seems
350 to set the magic properly. (Sartak)
352 * Class::MOP::Attribute
353 - The process_accessors method is now private. A public alias
354 exists (and will stick around for a few releases), but it
355 warns that calling the public method is deprecated.
357 * Class::MOP::Method::Generated
358 - Removed the new and _new methods, since this is an abstract
359 base class, and all existing subclasses implement their own
363 - Stop is_class_loaded from thinking a class is loaded if it
364 only has an empty GV (Florian Ragwitz).
365 - Add a test for this (Yappo).
366 - Refactor get_all_package_symbols to allow short-circuiting
368 - Use this in is_class_loaded (Florian Ragwitz).
369 - Stop segfaulting when trying to get the name from a sub that's
370 still being compiled (Florian Ragwitz).
371 - Add tests for this (Florian Ragwitz).
372 - Prefix all public symbols with "mop_" (Florian Ragwitz).
373 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
374 - Simplify creating simple xs reader methods (Florian Ragwitz).
375 - Make everything compile with c++ compilers (Florian Ragwitz).
376 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
379 - Remove optional test plans for tests depending on Sub::Name as
380 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
383 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
385 0.78 Mon, February 23, 2009
386 * No changes from 0.77_01
388 0.77_01 Sun, February 22, 2009
390 - This package now requires its XS components. Not using
391 Sub::Name lead to different behavior and bugginess in the pure
392 Perl version of the code. A Moose test would fail when run
393 against the pure Perl version of this code.
395 * Class::MOP::Instance
396 - The inline_* methods now quote attribute names themselves, and
397 don't expect to receive a quoted value.
400 0.77 Sat, February 14, 2009
402 - Avoid assertion errors on debugging perls in is_class_loaded
406 - Fixed various corner cases where is_class_loaded incorrectly
407 returned true for a class that wasn't really loaded. (Dave
411 - Add get_all_method_names (Sartak)
412 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
414 * Class::MOP::Package
415 - Disable deprecated get_all_package_symbols in list
416 context. (Florian Ragwitz)
419 - Make sure we generate a BSD-compatible Makefile (Florian
423 - The misspelled "check_metaclass_compatability" method we've
424 kept around for backwards compat_i_bility will be removed in a
425 near future release. You've been warned.
427 0.76 Thu, January 22, 2009
428 * Class::MOP::Method::Generated
429 - Added new private methods to support code generation, which
430 are being used by Moose and can be used by MooseX
432 - Generated methods are now generated with a #line directive
433 reflecting the source of the generated method. (nothingmuch)
436 - Clarified documentation of methods that return
437 Class::MOP::Method objects. (doy)
440 - Clarified documentation of the metaclass cache methods. (Sartak)
443 - Add test showing how the xs Class::MOP::is_class_loaded can
444 be made to operate differently to the pure perl version (t0m)
446 0.75 Wed, December 31, 2008
448 - A class that was made immutable and then mutable could end up
449 sharing an immutable transformer object
450 (Class::MOP::Immutable) with other classes, leading to all
451 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
453 0.74 Tue, December 25, 2008
455 - Add an xs implementation of Class::MOP::is_class_loaded (closes
456 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
457 - Changed internals to make prehashing of hash keys easier and less
458 error-prone. (Florian Ragwitz)
460 - Fix documentation to show that around modifiers happen on both
461 sides of the modified method. (Dave Rolsky)
463 0.73 Tue, December 16, 2008
465 - Don't use Perl_mro_meta_init. It's not part of the public perl
466 api. Fixes failures to build on Win32 (RT #41750). (Florian
468 * t/082_get_code_info.t
469 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
470 munger anonymous subs when under -d and so making the tests
471 succeed in that case.
473 0.72 Mon, December 8, 2008
474 * Class::MOP::Package
475 - Pass options to _new, so subclass' attributes can be
478 - In the docs, indicate that package_name and name are required
479 when calling ->wrap (Stefan O'Rear)
481 0.71_02 Fri, December 5, 2008
482 * Class::MOP::Immutable
483 - Added a new attribute, inlined_constructor, which is true if
484 the constructor was inlined.
485 * Class::MOP::Package
486 - Make get_all_package_symbols return a hash ref in scalar
487 context and deprecate calling it in list context with a
488 warning. (Florian Ragwitz)
490 - Various improvements and refactoring, making things more robust and
491 easier to maintain. (Florian Ragwitz)
493 0.71_01 Wed, December 3, 2008
495 - Add an "execute" method to invoke the body so
496 we can avoid using the coderef overload (Sartak)
497 * Class::MOP::Immutable
498 - When we memoize methods, get their results lazily
499 to remove some compile-time cost (Sartak)
500 - Small speedup from eliminating several method
503 - Some small internal tweaks to try to reduce the number of
504 times we call get_method_map when bootstrapping the MOP. This
505 might make loading Class::MOP (and Moose) a little
506 faster. (Dave Rolsky)
507 - Implemented an optional XS version of get_method_map. Mostly
508 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
509 help form Florian Ragwitz. (Dave Rolsky)
510 - Make the behaviour of of get_all_package_symbols (and
511 therefore get_method_map) consistent for stub methods. Report
512 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
514 0.71 Wed November 26, 2008
517 - Actual package creation has moved upward from
518 Class to Module so that Moose roles can share
521 0.70_01 Mon, November 19, 2008
523 - Fixes for failures with blead (Florian Ragwitz)
524 - Silenced compiler warnings (Florian Ragwitz)
526 0.70 Fri, November 14, 2008
528 - Fixed an odd corner case where the XS version of
529 get_all_package_symbols could cause a segfault. This only
530 happened with inlined constants in Perl 5.10.0 (Florian
533 0.69 Fri, November 7, 2008
534 * Class::MOP::Method::Wrapped
535 - Added introspection methods for method modifiers (Dave Rolsky)
538 0.68 Fri October 24, 2008
540 - Make load_class require by file name instead of module name.
541 This stops confusing error messages when loading '__PACKAGE__'.
543 - Add load_one_class_of function to enable you to load one of a
544 list of classes, rather than having to call load_class multiple
545 times in an eval. (t0m)
547 0.67 Tue October 14, 2008
549 - Call a method on the class after setting the superclass list
550 so that we can get Perl to detect cycles before MRO::Compat
551 spirals into an infinite loop (sartak)
552 - Reported by Schwern, [rt.cpan.org #39001]
553 - In create(), pass unused options on to initialize()
554 - added test for this
556 0.66 Sat September 20, 2008
557 !! This release has an incompatible change regarding !!
558 introspection of a class's method with Class::MOP::Class !!
561 - We (us maintainers) now run all tests with XS and then without
562 XS, which should help us catch skew between the XS/pure Perl
566 ! The alias_method method has been deprecated. It now simply
567 calls add_method instead. There is no distinction between
568 aliased methods and "real" methods.
570 This means that methods added via alias_method now show up as
571 part of the class's method list/map. This is a backwards
572 incompatible change, but seems unlikely to break any
573 code. Famous last words. (Dave Rolsky)
576 - Fixed the spelling of "compatibility", but we still have a
577 "check_metaclass_compatability" method for backwards
580 0.65 Mon September 1, 2008
581 For those not following the series of dev releases, the changes
582 from 0.64 from 0.65 can mostly be summed up as a lot performance
583 improvements by nothingmuch, including new optional XS versions of
584 some methods. Also, Class::MOP now works _without_ any XS modules,
585 for sad systems without a compiler.
588 - Added name and package_name XS accessors, and make sure all
589 the XS and Perl versions work the same way. (Dave Rolsky)
592 - The XS versions of various methods just returned undef when
593 called class methods, rather than dying like the pure Perl
594 versions. (Dave Rolsky)
596 0.64_07 Fri August 29, 2008
598 - Silenced warnings that managed to break Moose tests when XS
599 was loaded. (Dave Rolsky)
600 - Some XS versions of methods were ignored because of typos in
601 MOP.xs. (Dave Rolsky)
603 0.64_06 Mon August 25, 2008
604 * Class::MOP (MOP.xs)
605 - Another MS VC++ fix, cannot declare a variable in the middle
606 of a scope (Taro Nishino).
608 0.64_05 Sun August 24, 2008
610 - None of the dev releases actually loaded the XS properly, but
611 we silently fell back to the pure Perl version of the
614 * Class::MOP (MOP.xs)
615 - Replaced some code that used functions not available on Visual
616 C++ with some Perl XS API bits (Dave Rolsky).
618 0.64_04 Sat August 23, 2008
620 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
622 * pod.t and pod_coveraget.t
623 - These are no longer shipped with the tarball because of bogus
624 failures from CPAN testers. (Dave Rolsky)
626 0.64_03 Thu August 21, 2008
627 * Class::MOP::Package
628 - Some (legit) code was misparsed by earlier 5.8.x
629 releases. (nothingmuch)
632 - Fix a constant in void context warning (nothingmuch)
634 0.64_02 Thu August 21, 2008
635 * Makefile.PL and Class::MOP
636 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
639 - Add missing prereqs that got lost in the switch away from
642 * Class::MOP::Instance
643 - New method - get_all_attributes (nothingmuch)
645 0.64_01 Wed August 20, 2008
647 - We now check to see if you have a compiler. If you don't, the
648 module installs without some XS bits, but will work the same
649 as with XS. This should make it easier to install on platforms
650 without a compiler (like Windows). (Dave Rolsky)
653 - Perl 6 style attribute naming replaced with sane style ('methods', not
654 '%!methods'). These changes should not impact any existing API uses.
658 - Quite a number of optimizations based on profiling, including
659 allowing constructors to take hash references instead of
660 hashes, duplicating some frequently used code in XS, and
661 making constructors immutable. These changes should not impact
662 any existing API uses. (nothingmuch)
665 - Constructors now respect the meta attributes of their subclasses,
666 facilitating MOP extensibility. More related changes will happen in the
667 next several releases. (nothingmuch)
670 - New method - get_all_methods, replaces the deprecated
671 compute_all_applicable_methods. get_all_attributes provided for
672 consistency (nothingmuch)
673 - New method - wrap_method was refactored out of get_method_map
675 - New API for meta instance invalidation - invalidate_meta_instance,
676 invalidate_meta_instances, add_dependent_meta_instance,
677 remove_dependent_meta_instance, called automatically when attribute
678 definitions change and allows notification of dependent subclasses.
681 0.64 Sun August 3, 2008
682 * Class::MOP::Immutable
683 - fixing subtle edge case in immutable when you
685 - clean up option processing (nothingmuch)
687 * Class::MOP::Instance
688 - inlined initialize slot didn't match
689 non-inlined (nothingmuch)
691 0.63 Mon July 7, 2008
693 - load_class will initialize a metaclass even if
694 the class is already loaded (sartak)
695 - load_class now returns the metaclass instance
696 instead of just 1 (sartak)
699 - better error messages (sartak and Dave Rolsky)
701 0.62 Wed June 18, 2008
702 - in is_class_loaded, recognize scalar references (as opposed to globs) in
703 the symbol table as methods (these are optimized constant subs)
705 0.61 Fri. June 13, 2008
706 - Okay, lets give this another try and see if PAUSE
707 recognizes it correct this time.
709 0.60 Thurs. Jun 12, 2008
710 - Fixed a version number issue by bumping all modules
713 0.59 Thurs. Jun 12, 2008
714 !! Several fixes resulting in yet another 25-30% speedup !!
717 - now stores the instance of the instance
718 metaclass to avoid needless recomputation
719 and deletes it when the cache is blown
720 - introduce methods to query Class::MOP::Class for
721 the options used to make it immutable as well as
722 the proper immutable transformer. (groditi)
724 * Class::MOP::Package
725 - {add, has, get, remove}_package_symbol all
726 now accept a HASH ref argument as well as the
727 string. All internal usages now use the HASH
731 - MOP.xs does sanity checks on the coderef
733 - is_class_loaded check now uses code that
734 was improved in Moose's ClassName type
736 - nonsensical (undef, empty, reference) class
737 names now throw a more direct error in
739 - tests for this and other aspects of
745 Class::MOP::Method::Wrapped
746 Class::MOP::Attribute
747 - switched usage of reftype to ref because
750 0.58 Thurs. May 29, 2008
751 (late night release engineering)--
753 - fixing the version is META.yml, no functional
754 changes in this release
756 0.57 Wed. May 28, 2008
757 !! Several speedups resulting in 20-25% speedups !!
758 || (thanks to konobi, groditi, mst & CataMoose) !!
761 - made get_method_map use list_all_package_symbols
762 instead of manually grabbing each symbol
763 - streamlining &initialize somewhat, since it gets
766 * Class::MOP::Package
767 - made {get, has}_package_symbol not call
769 - inlining a few calls to &name with
770 direct HASH access key access
771 - added get_all_package_symbols to fetch
772 a HASH of items based on a type filter
773 similar to list_all_package_symbols
774 - added tests for this
777 Class::MOP::Method::Constructor
778 Class::MOP::Method::Generated
779 Class::MOP::Method::Accessor
780 - added more descriptive error message to help
781 keep people from wasting time tracking an error
782 that is easily fixed by upgrading.
784 * Class::MOP::Immutable
785 - Don't inline a destructor unless the user actually
787 - added tests for this
789 0.56 Saturday, May 24, 2008
791 - we now get the &check_package_cache_flag
792 function from MRO::Compat
793 - All XS based functionality now has a
794 Pure Perl alternative
795 - the CLASS_MOP_NO_XS environment variable
796 can now be used to force non-XS versions

807 - added the ability to "wrap" methods when
808 making the class immutable
811 - now handling the edge case of ->meta->identifier
812 dying by wrapping add_package_symbol to specifically
813 allow for it to work.
814 - added tests for this
816 * Class::MOP::Attribute
818 Class::MOP::Immutable
819 - any time a method meta object is constructed
820 we make sure to pass the correct package and
821 method name information
824 Class::MOP::Method::Wrapped
825 Class::MOP::Method::Generated
826 Class::MOP::Method::Accessor
827 Class::MOP::Method::Consructor
828 - the &wrap constructor method now requires that a
829 'package_name' and 'name' attribute are passed. This
830 is to help support the no-XS version, and will
831 throw an error if these are not supplied.
832 - all these classes are now bootstrapped properly
833 and now store the package_name and name attributes
836 ~ Build.PL has been removed since the
837 Module::Install support has been removed
839 0.55 Mon. April 28, 2008
840 - All classes now have proper C3 MRO support
841 - added MRO::Compat as a dependency to allow
842 for the C3 MRO support to Just Work in all
846 - rebless_instance now returns the instance
847 it has just blessed, this is mostly to
849 - set the attr correctly in rebless_instance
850 when it has no init_arg
851 - tweaked &linear_isa and &class_precedence_list
852 to support c3 classes.
854 0.54 Fri. March, 14, 2008
857 - making sure that load_class never gets
858 passed a value from @_ or $_ to squash
859 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
862 - make_{immutable,mutable} now return 1
864 - improved error handling in ->create method
865 - rebless_instance now takes extra params which
866 will be used to populate values
867 - added tests for this
870 - localizing the Data::Dumper configurations so
871 that it does not pollute others (RT #33509)
877 Class::MOP::Attribute
878 - these classes no longer define their own ->meta,
879 but instead just inherit from Class::MOP::Object
881 * Class::MOP::Instance
882 Class::MOP::Immutable
883 - these classes now inherit from Class::MOP::Object
886 - fixed the filename length on several
887 test files so we install on VMS better
889 - fixed incorrect use of catdir when it
890 should be catfile (RT #32385)
892 0.53 Thurs. Feb. 14, 1008
893 ~~ several doc. fixes and updates ~~
896 Class::MOP::Method::Constructor

899 to indicate that no constructor args can
900 be passed (thanks to nothingmuch)
901 - added tests for this
902 - added attribute initializer attribute (rjbs)
905 - making this use the new init_arg => undef
906 feature instead of the silly hack from
907 before (thanks to nothingmuch)
909 0.52 Tues. Jan. 22, 2008
911 - fixed bug in rebless_instance
914 * Class::MOP::Method::Constructor
915 - removed assumptions about the existence of
918 0.51 Mon. Jan. 14, 2008
919 ~~~ some misc. doc. fixes ~~~
920 ~~ updated copyright dates ~~
923 - now sets the IS_RUNNING_ON_5_10
924 constant so that we can take advantage
925 of some of the nice bits of 5.10
928 - uses the IS_RUNNING_ON_5_10 flag to
929 optimize the &linearized_isa method
930 and avoid the hack/check for circular
931 inheritence in &class_precedence_list
932 - added rebless_instance method (Sartak)
933 - added tests for this
935 * Class::MOP::Immutable
936 - the immutable class now keeps track of
937 the transformer which immutablized it

956 0.49 Fri. Dec. 14, 2007
957 !! Class::MOP now loads 2 x faster !!
958 !! with XS speedups (thanks konobi) !!
961 - removed the dependency on B
962 - added two XS functions (thanks konobi)
963 - get_code_info($code) which replaces all
964 the B fiddling we were doing with
965 faster/leaner XS level fiddling
966 - check_package_cache_flag($pkg_name) which
967 returns the PL_sub_generation variable to
968 be used to help manage method caching.
971 In 5.10 or greater this will actually
972 use the mro::get_pkg_gen instead to give
973 even more accurate caching information.
974 blblack++ for that stuff :)
977 - added the &subclasses method (thanks rlb)
978 - added the update_package_cache_flag and
979 reset_package_cache_flag which help keep
980 track of when we need to re-fetch the
982 - Several small improvements to take advantage
983 of the new method map caching features
985 0.48 Mon. Nov. 26, 2007
986 * Class::MOP::Attribute
987 - fixed get_read/write_method to handle the
988 HASH ref case, which makes the

990 - added more tests for this
992 0.47 Sat. Nov. 24, 2007
993 * Class::MOP::Attribute

1000 pruning duplicate classes (this will be even more
1001 useful in the 5.10-compat version coming soon)
1003 * Class::MOP::Attribute
1004 - added the get_read_method_ref and get_write_method_ref
1005 methods which allow you to retrieve a CODE ref which
1006 can always be used to read or write an attribute.
1008 0.45 Thurs. Nov. 13, 2007
1009 * Class::MOP::Attribute
1010 - Fix error message on confess (groditi)
1012 0.44 Thurs. Nov. 13, 2007

1023 call through (groditi)
1025 * Class::MOP::Attribute

1036 - removed the relevant attributes
1038 * Class::MOP::Method::Constructor
1039 - fixed the cached values we had to be more sane
1040 - made this a subclass of Class::MOP::Method::Generated
1041 - fixed generated constructor so it properly handles
1043 - added tests for this
1044 - added the option to allow for both inlined and
1045 non-inlined constructors.
1046 - Update inlined methods for builder and predicate changes (groditi)
1048 * Class::MOP::Method::Generated
1049 - added this class as an abstract base for the
1050 Class::MOP::Method::{Constructor,Accessor} classes
1051 - added tests for this

1064 - alter symbol table handling to deal with 5.8.x and 5.9.x
1067 - Get rid of the crappy workaround from 0.40/41
1069 0.41 Sun. July 15, 2007
1071 Arghh!!! My TODO test didn't work, so I handle
1072 it manually now so that people can use this
1073 with 5.9.5/bleadperl without issue.
1075 0.40 Tues, July 3, 2007
1077 ~ marked a test in 003_methods.t as TODO
1078 for perl 5.9.5 (this test is irrelvant to
1079 the module functioning on 5.9.5 for the most
1082 0.39 Mon. June 18, 2007
1083 * Class::MOP::Immutable
1084 - added make_metaclass_mutable + docs (groditi)
1085 - removed unused variable
1086 - added create_immutable_transformer
1087 necessary for sane overloading of immutable behavior
1088 - tests for this (groditi)
1091 - Immutability can now be undone,
1092 added make_mutable + tests + docs (groditi)
1093 - Massive changes to the way Immutable is done
1094 for details see comments next to make_immutable
1095 This fixes a bug where custom metaclasses broke
1096 when made immutable. We are now keeping one immutable
1097 metaclass instance per metaclass instead of just one
1098 to prevent isa hierarchy corruption. Memory use will go
1099 up, but I suspect it will be neglible.
1100 - New tests added for this behavior. (groditi)
1102 0.38 Thurs. May 31, 2007
1103 ~~ More documentation updates ~~
1105 * Class::MOP::Package
1106 - we now deal with stub methods properly
1107 - added tests for this
1108 - fixed some tests failing on 5.9.5 (thanks blblack)
1110 * Class::MOP::Attribute
1111 - added get_read_method and get_write_method
1112 thanks to groditi for this code, tests
1114 - added tests and POD for this
1117 - fixed RT issue #27329, clone object now
1118 handles undef values correctly.
1119 - added tests for this
1120 - Corrected anon-class handling so that they
1121 will not get reaped when instances still
1122 exist which need to reference them. This is
1123 the correct behavior, hopefully this is an
1124 obscure enough feature that there are not too
1125 many work arounds out in the wild.
1126 - added tests for this by groditi
1127 - updated docs to explain this
1130 - load custom metaclasses automatically (thanks groditi)
1131 - added tests for this behavior
1133 0.37 Sat. March 10, 2007
1134 ~~ Many, many documentation updates ~~
1137 - added &load_class and &is_class_loaded
1138 - added tests and docs for these
1140 * Class::MOP::Attribute

1142 avoid setting off bool-overloads (found by Carl Franks)
1146 - bad name in a test, causing meaningless failuress.
1151 ~~ GLOBAL CHANGES ~~
1152 - All attribute names are now consistent and follow Perl 6
1153 style (prefixed with the sigil, and ! as the twigil for
1154 private attrs). This should not affect any code, unless
1155 you broke encapsulation, in which case, it is your problem
1158 !! Class::MOP::Class::Immutable has been removed
1160 * Class::MOP::Method::Constructor
1161 - this has been moved out of Class::MOP::Class::Immutable
1162 and is a proper subclass of Class::MOP::Method now.
1165 - this module now uses Class::MOP::Immutable for the
1166 immutable transformation instead of
1167 Class::MOP::Class::Immutable.
1169 + Class::MOP::Immutable
1170 - this module now controls the transformation from a mutable
1171 to an immutable version of the class. Docs for this will
1172 be coming eventually.
1175 0.36 Sun. Nov. 5, 2006
1177 - added a few 'no warnings' lines to keep annoying
1178 (and meaningless) warnings from chirping during
1182 - some more bootstrapping is now done on the new
1185 * Class::MOP::Class::Immutable
1187 - constructor generation is now handled by
1188 the Class::MOP::Method::Constructor class
1190 * Class::MOP::Method::Constructor
1191 - created this to handle constructor generation
1192 in Class::MOP::Class::Immutable
1194 * Class::MOP::Attribute
1196 - attributes now delegate to the
1197 Class::MOP::Method::Accessor to generate
1200 * Class::MOP::Method::Accessor
1201 - all accessor generation functions from
1202 Class::MOP::Attribute have been moved here
1204 0.35 Sat. Sept. 30, 2006

1207 - initial prototype of a class browser, more
1208 on this to come. Comments and patches are
1212 - All Class::MOP::* accessors are no longer
1213 re-generated in the bootstrap, instead
1214 they are aliased from the originals
1215 - fixed tests to reflect
1216 - added Class::MOP::Method (and its subclasses)
1218 - adjusted tests for this
1219 - added the Class::MOP::Instance attributes
1222 * Class::MOP::Method

1225 but are actual objects which can be CODE-ified
1226 - adjusted tests to compensate
1227 - adjusted docs for this
1230 - changed how methods are dealt with to
1231 encapsulate most of the work into the
1232 &get_method_map method
1233 - made several adjustments for the change
1234 in Class::MOP::Method
1235 - &add_attribute now checks if you are adding
1236 a duplicate name, and properly removes the
1237 old one before installing the new one
1238 - added tests for this
1239 - adjusted docs for this
1241 * Class::MOP::Class::Immutable
1242 - added caching of &get_method_map
1243 - fixed issue with &get_package_symbol
1244 - cleaned up the methods that die (patch by David Wheeler)

1247 - added filtering capabilities to
1248 &list_all_package_symbols
1250 0.34 Sat. Aug. 26, 2006
1252 - added the %:methods attribute, which like
1253 the $:version and such just actually goes
1254 to the symbol table to get it's stuff.
1255 However, it makes the MOP more complete.
1257 - The &create method now requires that all
1258 but the package name now is passed in as
1259 named parameters. See docs for more info.
1260 - updated docs and tests for this
1262 * Class::MOP::Object
1263 - added &dump method to easily Data::Dumper

1285 are no longer allowed for defaults
1286 - added tests for this
1288 * Class::MOP::Package
1289 - fixed an issue with perl 5.8.1 and how it deals
1290 with symbol tables. The namespace hash is now
1291 always reloaded from the symbol table.
1293 ~ lots of misc. documentation cleanup
1295 0.32 Sat. Aug. 12, 2006
1296 + added Class::MOP::Object so that the
1297 metamodel is more complete (and closer
1298 to what Perl 6 will probably be).

1302 the primary gateway between the metaclass
1303 and the Perl 5 symbol table
1304 - added many tests for this
1305 - this class is now a subclass of
1307 - added some tests to reflect this

1311 use Class::MOP::Package methods instead
1313 * Class::MOP::Module
1314 - adding the $:version attribute in the bootstrap
1315 so that Module has a version as an attribute
1316 - see comment in Class::MOP for details
1317 - added the $:authority attribute to this module
1318 as well as an &identifier method, to bring us
1319 ever closer to Perl 6 goodness
1320 - I have added $AUTHORITY to all the modules
1321 - added tests for this

1337 anywhere within the class hierarchy
1339 * Class::MOP::Attribute
1340 - added &set_value and &get_value for getting
1341 the value of the attribute for a particular
1344 0.30 Wed. July 5, 2006
1345 ---------------------------------------
1346 This is the first version of Class::MOP
1347 to introduce the immutable features which
1348 will be used for optimizating the MOP.
1349 This support should still be considered
1350 experimental, but moving towards stability.
1351 ---------------------------------------
1353 * Created Class::MOP::Class::Immutable
1355 * Created the Class::MOP::Package and
1356 Class::MOP::Module classes to more
1357 closely conform to Perl 6's meta-model
1360 - now inherits from Class::MOP::Module
1361 - several methods moved to ::Module and
1362 ::Package and now inherited
1363 - added tests for this
1365 * Class::MOP::Instance
1366 - added an is_inlinable method to allow other
1367 classes to check before they attempt to optimize.
1368 - added an inline_create_instance to inline
1369 instance creation (of course)
1372 - the Class::MOP::Class::*_package_variable
1373 methods are all now methods of Class::MOP::Package
1374 and called *_package_symbol instead. This is
1375 because they are now more general purpose symbol
1376 table manipulation methods.
1378 0.29_02 Thurs. June 22, 2006
1379 ++ DEVELOPER RELEASE ++
1381 - small change in &create so that it behaves

1385 0.29_01 Fri. May 12, 2006
1386 ++ DEVELOPER RELEASE ++
1387 - This release works in combination with
1388 Moose 0.09_01, it is a developer release
1389 because it introduces a new instance

1433 - added tests for this
1434 - added get_all_metaclasses, get_all_metaclass_names
1435 and get_all_metaclass_instances method to allow
1436 access to all the cached metaclass objects.
1437 - attribute slot initialization is now the responsibility
1438 of the attribute itself, and construct_instance now
1439 delegates appropriately
1441 * Class::MOP::Attribute
1442 - attribute slot initialization is now the responsibility
1443 of the attribute itself, so we added a method for it
1444 called initialize_instance_slot
1447 - adjusted all the examples to use the new attribute
1448 initialize_instance_slot method

1473 0.21 Wed. March 15, 2006
1475 - fixed issue where metaclasses are reaped from

1479 0.20 Thurs. March 2, 2006
1480 - removed the dependency for Clone since
1481 we no longer to deep-cloning by default.
1483 * Class::MOP::Method

1507 0.12 Thurs. Feb 23, 2006
1508 - reduced the dependency on B, no need to always
1512 - added docs to the C3 method dispatch order test

1523 - added docs and tests
1525 0.10 Tues Feb. 14, 2006
1526 ** This release was mostly about writing more tests and
1527 cleaning out old and dusty code, the MOP should now
1528 be considered "ready to use".
1530 - adding more tests to get coverage up a little higher,
1531 mostly testing errors and edge cases.
1532 - test coverage is now at 99%
1535 - no longer optionally exports to UNIVERSAL::meta or
1536 creates a custom metaclass generator, use the
1537 metaclass pragma instead.
1540 - fixed a number of minor issues which came up in the
1541 error/edge-case tests
1543 * Class::MOP::Attribute
1544 - fixed a number of minor issues which came up in the

1548 - fixing the AttributesWithHistory example, it was broken.
1550 0.06 Thurs Feb. 9, 2006
1552 - adding new metaclass pragma to make setting up the
1553 metaclass a little more straightforward
1556 - clean up bootstrapping to include more complete
1557 attribute definitions for Class::MOP::Class and
1558 Class::MOP::Attribute (accessors, readers, writers,
1559 etc.) ... it is redundant, but is useful meta-info
1563 - fixing minor meta-circularity issue with &meta, it
1564 is now more useful for subclasses
1565 - added &get_attribute_map as an accessor for the
1566 hash of attribute meta objects
1567 - &compute_all_applicable_attributes now just returns
1568 the attribute meta-object, rather than the HASH ref
1569 since all the same info can be gotten from the
1570 attribute meta-object itself
1571 - updated docs & tests to reflect
1572 - added &clone_instance method which does a deep clone
1573 of the instance structure created by &construct_instance
1574 - added docs & tests for this
1575 - added Clone as a dependency
1576 - added &new_object and &clone_object convience methods to
1577 return blessed new or cloned instances
1578 - they handle Class::MOP::Class singletons correctly too
1579 - added docs & tests for this
1580 - cleaned up the &constuct_class_instance so that it behaves
1581 more like &construct_instance (and managed the singletons too)
1582 - added the &check_metaclass_compatibility method to make sure
1583 that metaclasses are upward and downward compatible.
1584 - added tests and docs for this
1587 - adjusting code to use the &Class::MOP::Class::meta
1589 - adjusting code to use the metaclass pragma
1591 0.05 Sat Feb. 4, 2006
1593 - added the &attribute_metaclass and &method_metaclass
1594 attributes which contain a metaclass name to use for
1595 attributes/methods respectively
1598 - bootstrap additional attributes for Class::MOP::Class
1601 - adjusted the example code and tests to use the new
1602 &attribute_metaclass feature of Class::MOP::Class
1603 - added new example:
1606 0.04 Fri Feb. 3, 2006
1608 - some documentation suggestions from #perl6
1610 * Class::MOP::Attribute

1633 - moving examples from t/lib/* to examples/*
1634 - adding POD documentation to the examples
