1 Revision history for Perl extension Class-MOP.
4 - Make is_class_loaded without any arguments fail loudly
8 - Stop add_method from behaving differently under the debugger
13 - Any method which takes a method name as an argument now allows names
14 which are false (like "0"), but the name must be defined and not be an
15 empty string. (Dave Rolsky)
18 - Deprecated get_attribute_map as a public method. You can use a
19 combination of get_attribute_list and get_attribute instead. (Dave
22 0.94 Tue, Sep 22, 2009
23 * Class::MOP::Attribute
24 - Introduce set_raw_value and get_raw_value, side effect free variants
25 of {get,set}_value. These don't do anything useful in Class::MOP but
26 have different behavior that set_value and get_value for Moose
27 attributes. (nothingmuch)
29 0.93 Tue, Sep 15, 2009
31 - The load_class function just returns true, since it's return value was
32 confusing (either a metaclass object or a class name). It either loads
33 a class or dies trying. In the future, this may change to not return
34 anything, since there's no point in checking its return
35 value. Addresses RT #45883. (Dave Rolsky)
37 * Class::MOP::Class::Trait::Immutable
38 - When throwing an error because of an immutable method, include that
39 method's name. Addresses RT #49680. (Shawn M Moore)
42 - Adding the same sub reference to multiple packages failed to update
43 the method map properly. RT #48985. Reported by Paul Mooney. (Dave
45 - The get_method_map method is now private (and called as
46 _full_method_map or _method_map). The public version is available as a
47 deprecated method. (Dave Rolsky)
49 0.92_01 Thu, Sep 10, 2009
51 - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
54 - Make sure XS code handles magical scalars correctly. (Goro Fuji)
57 - Documented the immutable_options method, which is useful if you need
58 to make a class mutable temporarily, and then nede to restore
59 immutability. (Dave Rolsky)
62 - Deprecated features have been moved to their own module,
63 Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)
68 - Move get_method_map and its various scaffolding into Package. (hdp)
71 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
72 the first argument, rather than just a coderef. (doy)
74 * Class::MOP::Attribute
76 - Allow attribute names to be false (while still requiring them to be
80 * Class::MOP::Method::Wrapped
81 - Fixing variable usage issues with the patch from previous
82 version, not properly using lexicals in the for
86 Japan Perl Association has sponsored Goro Fuji to improve startup
87 performance of Class::MOP and Moose. These enhancements may break
88 backwards compatibility if you're doing (or using) complex
89 metaprogramming, so, as always, test your code!
90 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
94 - Anonymous classes were not completely destroyed when they went
95 out of scope, leading to a memory leak. RT #47480. (Goro
99 - The get_method, has_method, and add_method methods no longer
100 use get_method_map. Method objects are instantiated
101 lazily. This significantly improves Class::MOP's load
105 - Inline fewer metaclass-level constructors since the ones we
106 have are perfectly fine. This reduces the number of string
109 * Class::MOP::Method::Wrapped
110 - If a method modifier set $_, this caused the modifier to blow
111 up, because of some weird internals. (Jeremy Stashewsky)
115 * Class::MOP::Class::Immutable::Trait
116 - Made the Trait act like a role with a bunch of "around"
117 modifiers, rather than sticking it in the inheritance
118 hierarchy. This fixes various problems that caused with
119 metaclass compatibility, which broke Fey::ORM.
122 - Allow a blessed code reference as the method body. Fixes a
123 problem interaction with MooseX::Types. (ash)
125 * Class::MOP::Instance
126 - add inline version of rebless_instance_structure. (doy)
127 - change inline_slot_access to use single quotes (gphat)
129 0.88 Tue, Jun 23, 2009
131 - Moved the __INSTANCE__ parameter to _construct_instance from
133 - Fixed some issues involving metaclasses of metaclasses and
136 0.87 Sun, Jun 21, 2009
138 - Made sure to always local-ize $@ and $SIG{__DIE__} before
139 calling an eval. Fixes RT #45973.
142 - Synced docs about immutability with the current reality (which
143 changed back in 0.82_01)
144 - Removed the immutable_transformer method, which had been
145 returning undef since 0.82_01 anyway.
148 - Got rid of tests which needed Moose and improved testing of
149 constructor/destructor inlining warnings. Fixes RT #47119.
151 0.86 Tue, Jun 16, 2009
153 - If you redefined a subroutine at runtime and then wrapped it
154 with a method modifier, the modifier could in some cases wrap
155 the original version of the subroutine. Fixes RT #46957.
158 - make_immutable issues a warning instead of overriding an
159 existing DESTROY method (Dylan William Hardison). Fixes RT
162 0.85 Sat, Jun 6, 2009
163 * Class::MOP::Attribute
164 - Allow default values to be Class::MOP::Methods. (Florian
166 - Test the above. (Rhesa Rozendaal)
167 - Tweak original commit so the intent matches the accepted
168 behavior (Nicholas Perez)
171 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
174 - Add direct_subclasses method (Sartak)
175 - Tests for subclasses and direct_subclasses (Sartak)
176 - subname is no longer used unconditionally in add_method, but
177 only if the code reference's name is '__ANON__' (nothingmuch)
178 - Add a hook for _superclasses_updated (Sartak)
181 - Remove long, old warning about possibly outdated modules
184 0.84 Tue, May 12, 2009
186 - Depend on Text::Exception 0.27 to avoid failing tests ond old
190 - Made is_class_loaded a little stricter. It was reporting that
191 a class was loaded if it merely had an @ISA variable in its
192 stash. Now it checks that the @ISA var has elements in it.
193 - Deprecate in_global_destruction and subname re-exporting
197 - Explicitly use Devel::GlobalDestruction and Sub::Name
200 * Class::MOP::Package
201 - Disable prototype mismatch warnings for add_package_symbol.
204 - Add test for finding methods from $meta->name->meta before immutable,
207 0.83 Mon, April 27, 2009
209 - Fix segfault when calling get_method_map on a metaclass for an empty
212 0.82_02 Fri, April 24, 2009
213 * Class::MOP::Method::Inlined
214 - Don't inline if the expected method is not defined at all (happens with
215 e.g. Moose::Object::_new is the expected method due to an overridden
218 - Some tests were trying to load Class::MOP::Immutable, which
219 was removed in 0.82_01.
221 0.82_01 Thu, April 23, 2009
222 * Class::MOP::Immutable (and others)
223 - Refactor the immutability system to use a pre-defined class
224 for the immutable metaclass of Class::MOP::Class::Immutable::$class
225 - Rather than generating methods into this class every time, use
226 a Trait (basic mixin) to supply the cached methods
227 - Remove the hack that returns the mutable metaclass for
228 metacircularity in order to provide consistent meta-metaclasses
229 for the Moose compatibility handling code
230 (mst broke it, nothingmuch fixed it)
232 0.82 Mon, April 20, 2009
234 - The deprecation wrappers for some renamed methods were not
235 passing arguments to the new method. (nothingmuch)
237 * Class::MOP::Immutable
238 - Warn during immutablization if the local class provides its own
239 constructor, to parallel the warning in Moose when a superclass
240 provides its own constructor (doy)
242 0.81 Tue, April 7, 2009
245 * Class::MOP::Instance
246 * Class::MOP::Attribute
247 * Class::MOP::Method::Accessor
248 * Class::MOP::Method::Constructor
249 - Include stack traces in the deprecation warnings introduced in
250 0.80_01. (Florian Ragwitz)
253 - Avoid c compiler warnings by declaring some unused function
254 arguments. (Florian Ragwitz)
256 0.80_01 Sun, April 5, 2009
258 - Make sure to preserve any compiler flags already defined in
259 Config.pm. Patch by Vincent Pit. RT #44739.
261 * Many methods have been renamed with a leading underscore, and a
262 few have been deprecated entirely. The methods with a leading
263 underscore are considered "internals only". People writing
264 subclasses or extensions to Class::MOP should feel free to
265 override them, but they are not for "public" use.
268 - construct_class_instance => _construct_class_instance (use new_object)
269 - construct_instance => _construct_instance (use new_object)
270 - check_metaclass_compatibility => _check_metaclass_compatibility
271 - create_meta_instance => _create_meta_instance (use get_meta_instance)
272 - clone_instance => _clone_instance (use clone_object)
273 - compute_all_applicable_methods is deprecated, use get_all_methods
274 - compute_all_applicable_attributes is deprecated, use get_all_attributes
276 - Class::MOP::Instance
277 - bless_instance_structure is deprecated and will be removed
281 - create has been renamed to _instantiate_module. This method
282 does not construct an object, it evals some code that
283 creates the relevant package in Perl's symbol table.
285 - Class::MOP::Method::Accessor
286 - initialize_body => _initialize_body (this is always called
287 when an object is constructed)
288 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
290 - Class::MOP::Method::Constructor
291 - initialize_body => _initialize_body (this is always called
292 when an object is constructed)
293 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
294 - attributes => _attributes
295 - meta_instance => _meta_instance
297 0.80 Wed, April 1, 2009
299 - Call user_class->meta in fewer places, with the eventual goal
300 of allowing the user to rename or exclude ->meta
301 altogether. Instead uses Class::MOP::class_of. (Sartak)
304 - New class_of function that should be used to retrieve a
305 metaclass. This is unlike get_metaclass_by_name in that it
306 accepts instances, not just class names. (Sartak)
309 - load_first_existing_class didn't actually load the first
310 existing class; instead, it loaded the first existing and
311 compiling class. It now throws an error if a class exists (in
312 @INC) but fails to compile. (hdp)
316 - we had some semi-buggy code that purported to provide a
317 HAS_ISAREV based on whether mro had get_isarev (due to an
318 oversight, it always returned 1). Since mro and MRO::Compat
319 have always had get_isarev, HAS_ISAREV was pointless. This
320 insight simplified the subclasses method by deleting the
321 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
323 0.79 Fri, March 29, 2009
324 * No changes from 0.78_02.
326 0.78_02 Thu, March 26, 2009
328 * Class::MOP::Immutable
329 - A big backwards-incompatible refactoring of the Immutable API,
330 and the make_immutable/make_mutable pieces of the Class
331 API. The core __PACKAGE__->meta->make_immutable API remains
332 the same, however, so this should only affect the most
336 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
337 has been fixed to be backwards compatible with 5.8.x.
340 - Add a hook for rebless_instance_away (Sartak)
341 - Use blessed instead of ref to get an instance's class name
342 in rebless_instance. (Sartak)
344 0.78_01 Wed, March 18, 2009
346 - Revised and reorganized all of the API documentation. All
347 classes now have (more or less) complete API documentation.
350 * Class::MOP::Instance
351 - Reblessing into a package that supports overloading wasn't
352 properly adding overload magic to the object due to a bug
353 in (at least) 5.8.8. We now use $_[1] directly which seems
354 to set the magic properly. (Sartak)
356 * Class::MOP::Attribute
357 - The process_accessors method is now private. A public alias
358 exists (and will stick around for a few releases), but it
359 warns that calling the public method is deprecated.
361 * Class::MOP::Method::Generated
362 - Removed the new and _new methods, since this is an abstract
363 base class, and all existing subclasses implement their own
367 - Stop is_class_loaded from thinking a class is loaded if it
368 only has an empty GV (Florian Ragwitz).
369 - Add a test for this (Yappo).
370 - Refactor get_all_package_symbols to allow short-circuiting
372 - Use this in is_class_loaded (Florian Ragwitz).
373 - Stop segfaulting when trying to get the name from a sub that's
374 still being compiled (Florian Ragwitz).
375 - Add tests for this (Florian Ragwitz).
376 - Prefix all public symbols with "mop_" (Florian Ragwitz).
377 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
378 - Simplify creating simple xs reader methods (Florian Ragwitz).
379 - Make everything compile with c++ compilers (Florian Ragwitz).
380 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
383 - Remove optional test plans for tests depending on Sub::Name as
384 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
387 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
389 0.78 Mon, February 23, 2009
390 * No changes from 0.77_01
392 0.77_01 Sun, February 22, 2009
394 - This package now requires its XS components. Not using
395 Sub::Name lead to different behavior and bugginess in the pure
396 Perl version of the code. A Moose test would fail when run
397 against the pure Perl version of this code.
399 * Class::MOP::Instance
400 - The inline_* methods now quote attribute names themselves, and
401 don't expect to receive a quoted value.
404 0.77 Sat, February 14, 2009
406 - Avoid assertion errors on debugging perls in is_class_loaded
410 - Fixed various corner cases where is_class_loaded incorrectly
411 returned true for a class that wasn't really loaded. (Dave
415 - Add get_all_method_names (Sartak)
416 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
418 * Class::MOP::Package
419 - Disable deprecated get_all_package_symbols in list
420 context. (Florian Ragwitz)
423 - Make sure we generate a BSD-compatible Makefile (Florian
427 - The misspelled "check_metaclass_compatability" method we've
428 kept around for backwards compat_i_bility will be removed in a
429 near future release. You've been warned.
431 0.76 Thu, January 22, 2009
432 * Class::MOP::Method::Generated
433 - Added new private methods to support code generation, which
434 are being used by Moose and can be used by MooseX
436 - Generated methods are now generated with a #line directive
437 reflecting the source of the generated method. (nothingmuch)
440 - Clarified documentation of methods that return
441 Class::MOP::Method objects. (doy)
444 - Clarified documentation of the metaclass cache methods. (Sartak)
447 - Add test showing how the xs Class::MOP::is_class_loaded can
448 be made to operate differently to the pure perl version (t0m)
450 0.75 Wed, December 31, 2008
452 - A class that was made immutable and then mutable could end up
453 sharing an immutable transformer object
454 (Class::MOP::Immutable) with other classes, leading to all
455 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
457 0.74 Tue, December 25, 2008
459 - Add an xs implementation of Class::MOP::is_class_loaded (closes
460 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
461 - Changed internals to make prehashing of hash keys easier and less
462 error-prone. (Florian Ragwitz)
464 - Fix documentation to show that around modifiers happen on both
465 sides of the modified method. (Dave Rolsky)
467 0.73 Tue, December 16, 2008
469 - Don't use Perl_mro_meta_init. It's not part of the public perl
470 api. Fixes failures to build on Win32 (RT #41750). (Florian
472 * t/082_get_code_info.t
473 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
474 munger anonymous subs when under -d and so making the tests
475 succeed in that case.
477 0.72 Mon, December 8, 2008
478 * Class::MOP::Package
479 - Pass options to _new, so subclass' attributes can be
482 - In the docs, indicate that package_name and name are required
483 when calling ->wrap (Stefan O'Rear)
485 0.71_02 Fri, December 5, 2008
486 * Class::MOP::Immutable
487 - Added a new attribute, inlined_constructor, which is true if
488 the constructor was inlined.
489 * Class::MOP::Package
490 - Make get_all_package_symbols return a hash ref in scalar
491 context and deprecate calling it in list context with a
492 warning. (Florian Ragwitz)
494 - Various improvements and refactoring, making things more robust and
495 easier to maintain. (Florian Ragwitz)
497 0.71_01 Wed, December 3, 2008
499 - Add an "execute" method to invoke the body so
500 we can avoid using the coderef overload (Sartak)
501 * Class::MOP::Immutable
502 - When we memoize methods, get their results lazily
503 to remove some compile-time cost (Sartak)
504 - Small speedup from eliminating several method
507 - Some small internal tweaks to try to reduce the number of
508 times we call get_method_map when bootstrapping the MOP. This
509 might make loading Class::MOP (and Moose) a little
510 faster. (Dave Rolsky)
511 - Implemented an optional XS version of get_method_map. Mostly
512 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
513 help form Florian Ragwitz. (Dave Rolsky)
514 - Make the behaviour of of get_all_package_symbols (and
515 therefore get_method_map) consistent for stub methods. Report
516 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
518 0.71 Wed November 26, 2008
521 - Actual package creation has moved upward from
522 Class to Module so that Moose roles can share
525 0.70_01 Mon, November 19, 2008
527 - Fixes for failures with blead (Florian Ragwitz)
528 - Silenced compiler warnings (Florian Ragwitz)
530 0.70 Fri, November 14, 2008
532 - Fixed an odd corner case where the XS version of
533 get_all_package_symbols could cause a segfault. This only
534 happened with inlined constants in Perl 5.10.0 (Florian
537 0.69 Fri, November 7, 2008
538 * Class::MOP::Method::Wrapped
539 - Added introspection methods for method modifiers (Dave Rolsky)
542 0.68 Fri October 24, 2008
544 - Make load_class require by file name instead of module name.
545 This stops confusing error messages when loading '__PACKAGE__'.
547 - Add load_one_class_of function to enable you to load one of a
548 list of classes, rather than having to call load_class multiple
549 times in an eval. (t0m)
551 0.67 Tue October 14, 2008
553 - Call a method on the class after setting the superclass list
554 so that we can get Perl to detect cycles before MRO::Compat
555 spirals into an infinite loop (sartak)
556 - Reported by Schwern, [rt.cpan.org #39001]
557 - In create(), pass unused options on to initialize()
558 - added test for this
560 0.66 Sat September 20, 2008
561 !! This release has an incompatible change regarding !!
562 introspection of a class's method with Class::MOP::Class !!
565 - We (us maintainers) now run all tests with XS and then without
566 XS, which should help us catch skew between the XS/pure Perl
570 ! The alias_method method has been deprecated. It now simply
571 calls add_method instead. There is no distinction between
572 aliased methods and "real" methods.
574 This means that methods added via alias_method now show up as
575 part of the class's method list/map. This is a backwards
576 incompatible change, but seems unlikely to break any
577 code. Famous last words. (Dave Rolsky)
580 - Fixed the spelling of "compatibility", but we still have a
581 "check_metaclass_compatability" method for backwards
584 0.65 Mon September 1, 2008
585 For those not following the series of dev releases, the changes
586 from 0.64 from 0.65 can mostly be summed up as a lot performance
587 improvements by nothingmuch, including new optional XS versions of
588 some methods. Also, Class::MOP now works _without_ any XS modules,
589 for sad systems without a compiler.
592 - Added name and package_name XS accessors, and make sure all
593 the XS and Perl versions work the same way. (Dave Rolsky)
596 - The XS versions of various methods just returned undef when
597 called class methods, rather than dying like the pure Perl
598 versions. (Dave Rolsky)
600 0.64_07 Fri August 29, 2008
602 - Silenced warnings that managed to break Moose tests when XS
603 was loaded. (Dave Rolsky)
604 - Some XS versions of methods were ignored because of typos in
605 MOP.xs. (Dave Rolsky)
607 0.64_06 Mon August 25, 2008
608 * Class::MOP (MOP.xs)
609 - Another MS VC++ fix, cannot declare a variable in the middle
610 of a scope (Taro Nishino).
612 0.64_05 Sun August 24, 2008
614 - None of the dev releases actually loaded the XS properly, but
615 we silently fell back to the pure Perl version of the
618 * Class::MOP (MOP.xs)
619 - Replaced some code that used functions not available on Visual
620 C++ with some Perl XS API bits (Dave Rolsky).
622 0.64_04 Sat August 23, 2008
624 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
626 * pod.t and pod_coveraget.t
627 - These are no longer shipped with the tarball because of bogus
628 failures from CPAN testers. (Dave Rolsky)
630 0.64_03 Thu August 21, 2008
631 * Class::MOP::Package
632 - Some (legit) code was misparsed by earlier 5.8.x
633 releases. (nothingmuch)
636 - Fix a constant in void context warning (nothingmuch)
638 0.64_02 Thu August 21, 2008
639 * Makefile.PL and Class::MOP
640 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
643 - Add missing prereqs that got lost in the switch away from
646 * Class::MOP::Instance
647 - New method - get_all_attributes (nothingmuch)
649 0.64_01 Wed August 20, 2008
651 - We now check to see if you have a compiler. If you don't, the
652 module installs without some XS bits, but will work the same
653 as with XS. This should make it easier to install on platforms
654 without a compiler (like Windows). (Dave Rolsky)
657 - Perl 6 style attribute naming replaced with sane style ('methods', not
658 '%!methods'). These changes should not impact any existing API uses.
662 - Quite a number of optimizations based on profiling, including
663 allowing constructors to take hash references instead of
664 hashes, duplicating some frequently used code in XS, and
665 making constructors immutable. These changes should not impact
666 any existing API uses. (nothingmuch)
669 - Constructors now respect the meta attributes of their subclasses,
670 facilitating MOP extensibility. More related changes will happen in the
671 next several releases. (nothingmuch)
674 - New method - get_all_methods, replaces the deprecated
675 compute_all_applicable_methods. get_all_attributes provided for
676 consistency (nothingmuch)
677 - New method - wrap_method was refactored out of get_method_map
679 - New API for meta instance invalidation - invalidate_meta_instance,
680 invalidate_meta_instances, add_dependent_meta_instance,
681 remove_dependent_meta_instance, called automatically when attribute
682 definitions change and allows notification of dependent subclasses.
685 0.64 Sun August 3, 2008
686 * Class::MOP::Immutable
687 - fixing subtle edge case in immutable when you
689 - clean up option processing (nothingmuch)
691 * Class::MOP::Instance
692 - inlined initialize slot didn't match
693 non-inlined (nothingmuch)
695 0.63 Mon July 7, 2008
697 - load_class will initialize a metaclass even if
698 the class is already loaded (sartak)

700 instead of just 1 (sartak)
703 - better error messages (sartak and Dave Rolsky)
705 0.62 Wed June 18, 2008
706 - in is_class_loaded, recognize scalar references (as opposed to globs) in
707 the symbol table as methods (these are optimized constant subs)
709 0.61 Fri. June 13, 2008
710 - Okay, lets give this another try and see if PAUSE
711 recognizes it correct this time.
713 0.60 Thurs. Jun 12, 2008
714 - Fixed a version number issue by bumping all modules
717 0.59 Thurs. Jun 12, 2008
718 !! Several fixes resulting in yet another 25-30% speedup !!
721 - now stores the instance of the instance
722 metaclass to avoid needless recomputation
723 and deletes it when the cache is blown
724 - introduce methods to query Class::MOP::Class for
725 the options used to make it immutable as well as
726 the proper immutable transformer. (groditi)
728 * Class::MOP::Package
729 - {add, has, get, remove}_package_symbol all
730 now accept a HASH ref argument as well as the
731 string. All internal usages now use the HASH
735 - MOP.xs does sanity checks on the coderef
737 - is_class_loaded check now uses code that
738 was improved in Moose's ClassName type
740 - nonsensical (undef, empty, reference) class
741 names now throw a more direct error in
743 - tests for this and other aspects of
749 Class::MOP::Method::Wrapped
750 Class::MOP::Attribute
751 - switched usage of reftype to ref because
754 0.58 Thurs. May 29, 2008
755 (late night release engineering)--
757 - fixing the version is META.yml, no functional
758 changes in this release
760 0.57 Wed. May 28, 2008
761 !! Several speedups resulting in 20-25% speedups !!
762 || (thanks to konobi, groditi, mst & CataMoose) !!
765 - made get_method_map use list_all_package_symbols
766 instead of manually grabbing each symbol
767 - streamlining &initialize somewhat, since it gets
770 * Class::MOP::Package
771 - made {get, has}_package_symbol not call
773 - inlining a few calls to &name with
774 direct HASH access key access
775 - added get_all_package_symbols to fetch
776 a HASH of items based on a type filter
777 similar to list_all_package_symbols
778 - added tests for this
781 Class::MOP::Method::Constructor
782 Class::MOP::Method::Generated
783 Class::MOP::Method::Accessor
784 - added more descriptive error message to help
785 keep people from wasting time tracking an error
786 that is easily fixed by upgrading.
788 * Class::MOP::Immutable
789 - Don't inline a destructor unless the user actually
791 - added tests for this
793 0.56 Saturday, May 24, 2008
795 - we now get the &check_package_cache_flag
796 function from MRO::Compat
797 - All XS based functionality now has a
798 Pure Perl alternative
799 - the CLASS_MOP_NO_XS environment variable
800 can now be used to force non-XS versions

811 - added the ability to "wrap" methods when
812 making the class immutable
815 - now handling the edge case of ->meta->identifier
816 dying by wrapping add_package_symbol to specifically
817 allow for it to work.
818 - added tests for this
820 * Class::MOP::Attribute
822 Class::MOP::Immutable
823 - any time a method meta object is constructed
824 we make sure to pass the correct package and
825 method name information
828 Class::MOP::Method::Wrapped
829 Class::MOP::Method::Generated
830 Class::MOP::Method::Accessor
831 Class::MOP::Method::Consructor
832 - the &wrap constructor method now requires that a
833 'package_name' and 'name' attribute are passed. This
834 is to help support the no-XS version, and will
835 throw an error if these are not supplied.
836 - all these classes are now bootstrapped properly
837 and now store the package_name and name attributes
840 ~ Build.PL has been removed since the
841 Module::Install support has been removed
843 0.55 Mon. April 28, 2008
844 - All classes now have proper C3 MRO support
845 - added MRO::Compat as a dependency to allow
846 for the C3 MRO support to Just Work in all
850 - rebless_instance now returns the instance
851 it has just blessed, this is mostly to
853 - set the attr correctly in rebless_instance
854 when it has no init_arg
855 - tweaked &linear_isa and &class_precedence_list
856 to support c3 classes.
858 0.54 Fri. March, 14, 2008
861 - making sure that load_class never gets
862 passed a value from @_ or $_ to squash
863 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
866 - make_{immutable,mutable} now return 1
868 - improved error handling in ->create method
869 - rebless_instance now takes extra params which
870 will be used to populate values
871 - added tests for this
874 - localizing the Data::Dumper configurations so
875 that it does not pollute others (RT #33509)
881 Class::MOP::Attribute
882 - these classes no longer define their own ->meta,
883 but instead just inherit from Class::MOP::Object
885 * Class::MOP::Instance
886 Class::MOP::Immutable
887 - these classes now inherit from Class::MOP::Object
890 - fixed the filename length on several
891 test files so we install on VMS better
893 - fixed incorrect use of catdir when it
894 should be catfile (RT #32385)
896 0.53 Thurs. Feb. 14, 1008
897 ~~ several doc. fixes and updates ~~
900 Class::MOP::Method::Constructor

903 to indicate that no constructor args can
904 be passed (thanks to nothingmuch)
905 - added tests for this
906 - added attribute initializer attribute (rjbs)
909 - making this use the new init_arg => undef
910 feature instead of the silly hack from
911 before (thanks to nothingmuch)
913 0.52 Tues. Jan. 22, 2008
915 - fixed bug in rebless_instance
918 * Class::MOP::Method::Constructor
919 - removed assumptions about the existence of
922 0.51 Mon. Jan. 14, 2008
923 ~~~ some misc. doc. fixes ~~~
924 ~~ updated copyright dates ~~
927 - now sets the IS_RUNNING_ON_5_10
928 constant so that we can take advantage
929 of some of the nice bits of 5.10
932 - uses the IS_RUNNING_ON_5_10 flag to
933 optimize the &linearized_isa method
934 and avoid the hack/check for circular
935 inheritence in &class_precedence_list
936 - added rebless_instance method (Sartak)
937 - added tests for this
939 * Class::MOP::Immutable
940 - the immutable class now keeps track of
941 the transformer which immutablized it
943 * Class::MOP::Instance
944 - added rebless_instance_structure method (Sartak)
945 - added tests for this
947 0.50 Fri. Dec. 21, 2007

961 !! Class::MOP now loads 2 x faster !!
962 !! with XS speedups (thanks konobi) !!
965 - removed the dependency on B
966 - added two XS functions (thanks konobi)
967 - get_code_info($code) which replaces all
968 the B fiddling we were doing with
969 faster/leaner XS level fiddling
970 - check_package_cache_flag($pkg_name) which
971 returns the PL_sub_generation variable to
972 be used to help manage method caching.
975 In 5.10 or greater this will actually
976 use the mro::get_pkg_gen instead to give
977 even more accurate caching information.
978 blblack++ for that stuff :)
981 - added the &subclasses method (thanks rlb)
982 - added the update_package_cache_flag and
983 reset_package_cache_flag which help keep
984 track of when we need to re-fetch the
986 - Several small improvements to take advantage
987 of the new method map caching features
989 0.48 Mon. Nov. 26, 2007
990 * Class::MOP::Attribute
991 - fixed get_read/write_method to handle the
992 HASH ref case, which makes the

994 - added more tests for this
996 0.47 Sat. Nov. 24, 2007
997 * Class::MOP::Attribute

999 - added more tests for this
1001 0.46 Fri. Nov. 23, 2007
1003 - added the linearized_isa method instead of constantly
1004 pruning duplicate classes (this will be even more
1005 useful in the 5.10-compat version coming soon)
1007 * Class::MOP::Attribute
1008 - added the get_read_method_ref and get_write_method_ref
1009 methods which allow you to retrieve a CODE ref which
1010 can always be used to read or write an attribute.
1012 0.45 Thurs. Nov. 13, 2007
1013 * Class::MOP::Attribute
1014 - Fix error message on confess (groditi)
1016 0.44 Thurs. Nov. 13, 2007

1027 call through (groditi)
1029 * Class::MOP::Attribute

1040 - removed the relevant attributes
1042 * Class::MOP::Method::Constructor
1043 - fixed the cached values we had to be more sane
1044 - made this a subclass of Class::MOP::Method::Generated
1045 - fixed generated constructor so it properly handles
1047 - added tests for this
1048 - added the option to allow for both inlined and
1049 non-inlined constructors.
1050 - Update inlined methods for builder and predicate changes (groditi)
1052 * Class::MOP::Method::Generated
1053 - added this class as an abstract base for the
1054 Class::MOP::Method::{Constructor,Accessor} classes
1055 - added tests for this
1058 - Alter tests (005, 014 020, 021) for new builder addition (groditi)

1068 - alter symbol table handling to deal with 5.8.x and 5.9.x
1071 - Get rid of the crappy workaround from 0.40/41
1073 0.41 Sun. July 15, 2007
1075 Arghh!!! My TODO test didn't work, so I handle
1076 it manually now so that people can use this
1077 with 5.9.5/bleadperl without issue.
1079 0.40 Tues, July 3, 2007
1081 ~ marked a test in 003_methods.t as TODO
1082 for perl 5.9.5 (this test is irrelvant to
1083 the module functioning on 5.9.5 for the most
1086 0.39 Mon. June 18, 2007
1087 * Class::MOP::Immutable
1088 - added make_metaclass_mutable + docs (groditi)
1089 - removed unused variable
1090 - added create_immutable_transformer
1091 necessary for sane overloading of immutable behavior
1092 - tests for this (groditi)
1095 - Immutability can now be undone,
1096 added make_mutable + tests + docs (groditi)
1097 - Massive changes to the way Immutable is done
1098 for details see comments next to make_immutable
1099 This fixes a bug where custom metaclasses broke
1100 when made immutable. We are now keeping one immutable
1101 metaclass instance per metaclass instead of just one
1102 to prevent isa hierarchy corruption. Memory use will go
1103 up, but I suspect it will be neglible.
1104 - New tests added for this behavior. (groditi)
1106 0.38 Thurs. May 31, 2007
1107 ~~ More documentation updates ~~
1109 * Class::MOP::Package
1110 - we now deal with stub methods properly
1111 - added tests for this
1112 - fixed some tests failing on 5.9.5 (thanks blblack)
1114 * Class::MOP::Attribute
1115 - added get_read_method and get_write_method
1116 thanks to groditi for this code, tests
1118 - added tests and POD for this
1121 - fixed RT issue #27329, clone object now
1122 handles undef values correctly.
1123 - added tests for this
1124 - Corrected anon-class handling so that they
1125 will not get reaped when instances still
1126 exist which need to reference them. This is
1127 the correct behavior, hopefully this is an
1128 obscure enough feature that there are not too
1129 many work arounds out in the wild.
1130 - added tests for this by groditi
1131 - updated docs to explain this
1134 - load custom metaclasses automatically (thanks groditi)
1135 - added tests for this behavior
1137 0.37 Sat. March 10, 2007
1138 ~~ Many, many documentation updates ~~
1141 - added &load_class and &is_class_loaded
1142 - added tests and docs for these
1144 * Class::MOP::Attribute
1145 - default now checks the instance with defined to
1146 avoid setting off bool-overloads (found by Carl Franks)
1150 - bad name in a test, causing meaningless failuress.
1155 ~~ GLOBAL CHANGES ~~
1156 - All attribute names are now consistent and follow Perl 6
1157 style (prefixed with the sigil, and ! as the twigil for
1158 private attrs). This should not affect any code, unless
1159 you broke encapsulation, in which case, it is your problem
1162 !! Class::MOP::Class::Immutable has been removed
1164 * Class::MOP::Method::Constructor
1165 - this has been moved out of Class::MOP::Class::Immutable
1166 and is a proper subclass of Class::MOP::Method now.
1169 - this module now uses Class::MOP::Immutable for the
1170 immutable transformation instead of
1171 Class::MOP::Class::Immutable.
1173 + Class::MOP::Immutable
1174 - this module now controls the transformation from a mutable
1175 to an immutable version of the class. Docs for this will
1176 be coming eventually.
1179 0.36 Sun. Nov. 5, 2006
1181 - added a few 'no warnings' lines to keep annoying
1182 (and meaningless) warnings from chirping during
1186 - some more bootstrapping is now done on the new
1189 * Class::MOP::Class::Immutable
1191 - constructor generation is now handled by
1192 the Class::MOP::Method::Constructor class
1194 * Class::MOP::Method::Constructor
1195 - created this to handle constructor generation
1196 in Class::MOP::Class::Immutable
1198 * Class::MOP::Attribute
1200 - attributes now delegate to the
1201 Class::MOP::Method::Accessor to generate
1204 * Class::MOP::Method::Accessor
1205 - all accessor generation functions from
1206 Class::MOP::Attribute have been moved here
1208 0.35 Sat. Sept. 30, 2006

1211 - initial prototype of a class browser, more
1212 on this to come. Comments and patches are
1216 - All Class::MOP::* accessors are no longer
1217 re-generated in the bootstrap, instead
1218 they are aliased from the originals
1219 - fixed tests to reflect
1220 - added Class::MOP::Method (and its subclasses)
1222 - adjusted tests for this
1223 - added the Class::MOP::Instance attributes
1226 * Class::MOP::Method

1229 but are actual objects which can be CODE-ified
1230 - adjusted tests to compensate
1231 - adjusted docs for this
1234 - changed how methods are dealt with to
1235 encapsulate most of the work into the
1236 &get_method_map method
1237 - made several adjustments for the change
1238 in Class::MOP::Method
1239 - &add_attribute now checks if you are adding
1240 a duplicate name, and properly removes the
1241 old one before installing the new one
1242 - added tests for this
1243 - adjusted docs for this
1245 * Class::MOP::Class::Immutable
1246 - added caching of &get_method_map
1247 - fixed issue with &get_package_symbol
1248 - cleaned up the methods that die (patch by David Wheeler)

1251 - added filtering capabilities to
1252 &list_all_package_symbols
1254 0.34 Sat. Aug. 26, 2006
1256 - added the %:methods attribute, which like
1257 the $:version and such just actually goes
1258 to the symbol table to get it's stuff.
1259 However, it makes the MOP more complete.
1261 - The &create method now requires that all
1262 but the package name now is passed in as
1263 named parameters. See docs for more info.
1264 - updated docs and tests for this
1266 * Class::MOP::Object
1267 - added &dump method to easily Data::Dumper

1289 are no longer allowed for defaults
1290 - added tests for this
1292 * Class::MOP::Package
1293 - fixed an issue with perl 5.8.1 and how it deals
1294 with symbol tables. The namespace hash is now
1295 always reloaded from the symbol table.
1297 ~ lots of misc. documentation cleanup
1299 0.32 Sat. Aug. 12, 2006
1300 + added Class::MOP::Object so that the
1301 metamodel is more complete (and closer
1302 to what Perl 6 will probably be).

1306 the primary gateway between the metaclass
1307 and the Perl 5 symbol table
1308 - added many tests for this

1315 use Class::MOP::Package methods instead
1317 * Class::MOP::Module
1318 - adding the $:version attribute in the bootstrap
1319 so that Module has a version as an attribute
1320 - see comment in Class::MOP for details
1321 - added the $:authority attribute to this module
1322 as well as an &identifier method, to bring us
1323 ever closer to Perl 6 goodness
1324 - I have added $AUTHORITY to all the modules
1325 - added tests for this

1341 anywhere within the class hierarchy
1343 * Class::MOP::Attribute
1344 - added &set_value and &get_value for getting
1345 the value of the attribute for a particular
1348 0.30 Wed. July 5, 2006
1349 ---------------------------------------
1350 This is the first version of Class::MOP
1351 to introduce the immutable features which
1352 will be used for optimizating the MOP.
1353 This support should still be considered
1354 experimental, but moving towards stability.
1355 ---------------------------------------
1357 * Created Class::MOP::Class::Immutable
1359 * Created the Class::MOP::Package and
1360 Class::MOP::Module classes to more
1361 closely conform to Perl 6's meta-model
1364 - now inherits from Class::MOP::Module
1365 - several methods moved to ::Module and
1366 ::Package and now inherited
1367 - added tests for this
1369 * Class::MOP::Instance
1370 - added an is_inlinable method to allow other
1371 classes to check before they attempt to optimize.
1372 - added an inline_create_instance to inline
1373 instance creation (of course)
1376 - the Class::MOP::Class::*_package_variable
1377 methods are all now methods of Class::MOP::Package
1378 and called *_package_symbol instead. This is
1379 because they are now more general purpose symbol
1380 table manipulation methods.
1382 0.29_02 Thurs. June 22, 2006
1383 ++ DEVELOPER RELEASE ++
1385 - small change in &create so that it behaves
1386 properly when inherited
1387 - small fix to &clone_instance
1389 0.29_01 Fri. May 12, 2006
1390 ++ DEVELOPER RELEASE ++
1391 - This release works in combination with
1392 Moose 0.09_01, it is a developer release
1393 because it introduces a new instance
1394 sub-protocol and has not yet been
1398 - anon-classes are now properly garbage collected
1399 - added tests for this
1400 - improved method modifier wrapping

1417 - added ArrayBasedStorage example to show
1418 instance storage using ARRAY refs instead of
1420 - added tests for this

1437 - added tests for this
1438 - added get_all_metaclasses, get_all_metaclass_names
1439 and get_all_metaclass_instances method to allow
1440 access to all the cached metaclass objects.
1441 - attribute slot initialization is now the responsibility
1442 of the attribute itself, and construct_instance now
1443 delegates appropriately
1445 * Class::MOP::Attribute
1446 - attribute slot initialization is now the responsibility
1447 of the attribute itself, so we added a method for it
1448 called initialize_instance_slot

1477 0.21 Wed. March 15, 2006
1479 - fixed issue where metaclasses are reaped from
1480 our cache in global destruction, and so are not
1481 available in DESTORY calls
1483 0.20 Thurs. March 2, 2006
1484 - removed the dependency for Clone since
1485 we no longer to deep-cloning by default.
1487 * Class::MOP::Method

1511 0.12 Thurs. Feb 23, 2006
1512 - reduced the dependency on B, no need to always
1516 - added docs to the C3 method dispatch order test

1527 - added docs and tests
1529 0.10 Tues Feb. 14, 2006
1530 ** This release was mostly about writing more tests and
1531 cleaning out old and dusty code, the MOP should now
1532 be considered "ready to use".
1534 - adding more tests to get coverage up a little higher,
1535 mostly testing errors and edge cases.
1536 - test coverage is now at 99%
1539 - no longer optionally exports to UNIVERSAL::meta or
1540 creates a custom metaclass generator, use the
1541 metaclass pragma instead.
1544 - fixed a number of minor issues which came up in the
1545 error/edge-case tests
1547 * Class::MOP::Attribute
1548 - fixed a number of minor issues which came up in the

1554 0.06 Thurs Feb. 9, 2006
1556 - adding new metaclass pragma to make setting up the
1557 metaclass a little more straightforward
1560 - clean up bootstrapping to include more complete
1561 attribute definitions for Class::MOP::Class and
1562 Class::MOP::Attribute (accessors, readers, writers,
1563 etc.) ... it is redundant, but is useful meta-info
1567 - fixing minor meta-circularity issue with &meta, it
1568 is now more useful for subclasses
1569 - added &get_attribute_map as an accessor for the
1570 hash of attribute meta objects
1571 - &compute_all_applicable_attributes now just returns
1572 the attribute meta-object, rather than the HASH ref
1573 since all the same info can be gotten from the
1574 attribute meta-object itself
1575 - updated docs & tests to reflect
1576 - added &clone_instance method which does a deep clone
1577 of the instance structure created by &construct_instance
1578 - added docs & tests for this
1579 - added Clone as a dependency
1580 - added &new_object and &clone_object convience methods to
1581 return blessed new or cloned instances
1582 - they handle Class::MOP::Class singletons correctly too
1583 - added docs & tests for this
1584 - cleaned up the &constuct_class_instance so that it behaves
1585 more like &construct_instance (and managed the singletons too)
1586 - added the &check_metaclass_compatibility method to make sure
1587 that metaclasses are upward and downward compatible.
1588 - added tests and docs for this
1591 - adjusting code to use the &Class::MOP::Class::meta
1593 - adjusting code to use the metaclass pragma
1595 0.05 Sat Feb. 4, 2006
1597 - added the &attribute_metaclass and &method_metaclass
1598 attributes which contain a metaclass name to use for
1599 attributes/methods respectively
1602 - bootstrap additional attributes for Class::MOP::Class
1605 - adjusted the example code and tests to use the new
1606 &attribute_metaclass feature of Class::MOP::Class
1607 - added new example:
1610 0.04 Fri Feb. 3, 2006
1612 - some documentation suggestions from #perl6
