1 Revision history for Perl extension Class-MOP.
7 * Packages and modules no longer have methods - this functionality was
8 moved back up into Class::MOP::Class (doy).
12 * Metaclass incompatibility checking now checks all metaclass types. (doy)
14 * Class::MOP can now do simple metaclass incompatibility fixing: if your
15 class's metaclass is a subclass of your parent class's metaclass, it will
16 just use the parent class's metaclass directly. (doy)
22 * is_class_loaded, load_class and load_first_existing_class now allow
23 specifying a minimum required version (Florian Ragwitz).
27 * The __INSTANCE__ parameter to Class::MOP::Class::new_object now enforces
28 that the passed in reference is blessed into the correct class (by dying if
29 it's not) (doy, jhallock).
31 1.00 Thu, Mar 25, 2010
33 [GRRR< FUCKING STEVAN@]
35 * Re-release 0.99 as 1.00.
37 0.99 Thu, Mar 25, 2010
41 * Fix typo in Class::MOP::Attribute (Franck Cuny).
43 0.98 Mon, Jan 18, 2010
47 * Added Class::MOP::Class->rebless_instance_back, which does the inverse of
48 rebless_instance (doy, rafl).
50 0.97_01 Mon, Jan 4, 2010
54 * Internal refactorings to move shared behavior into new "mixin" classes. This
55 made adding some new features to Moose much easier. (Dave Rolsky)
57 0.97 Fri, Dec 18, 2009
58 * No code changes, just packaging fixes to make this distro installable.
60 0.96 Fri, Dec 18, 2009
62 - Fixed t/082_get_code_info.t so it passes with bleadperl. (Dave Rolsky)
63 - Add XS & C files to no tabs check (Dave Rolsky)
64 - Convert all tests to done_testing. (Florian Ragwitz)
66 0.95 Wed, Nov 19, 2009
68 - Make is_class_loaded without any arguments fail loudly
70 - Make load_class throw more standard error messages when loading single
71 modules (nothingmuch).
74 - Stop add_method from behaving differently under the debugger
79 - Any method which takes a method name as an argument now allows names
80 which are false (like "0"), but the name must be defined and not be an
81 empty string. (Dave Rolsky)
84 - Deprecated get_attribute_map as a public method. You can use a
85 combination of get_attribute_list and get_attribute instead. (Dave
88 0.94 Tue, Sep 22, 2009
89 * Class::MOP::Attribute
90 - Introduce set_raw_value and get_raw_value, side effect free variants
91 of {get,set}_value. These don't do anything useful in Class::MOP but
92 have different behavior that set_value and get_value for Moose
93 attributes. (nothingmuch)
95 0.93 Tue, Sep 15, 2009
97 - The load_class function just returns true, since it's return value was
98 confusing (either a metaclass object or a class name). It either loads
99 a class or dies trying. In the future, this may change to not return
100 anything, since there's no point in checking its return
101 value. Addresses RT #45883. (Dave Rolsky)
103 * Class::MOP::Class::Trait::Immutable
104 - When throwing an error because of an immutable method, include that
105 method's name. Addresses RT #49680. (Shawn M Moore)
107 * Class::MOP::Package
108 - Adding the same sub reference to multiple packages failed to update
109 the method map properly. RT #48985. Reported by Paul Mooney. (Dave
111 - The get_method_map method is now private (and called as
112 _full_method_map or _method_map). The public version is available as a
113 deprecated method. (Dave Rolsky)
115 0.92_01 Thu, Sep 10, 2009
116 * Class::MOP::Package
117 - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
120 - Make sure XS code handles magical scalars correctly. (Goro Fuji)
123 - Documented the immutable_options method, which is useful if you need
124 to make a class mutable temporarily, and then nede to restore
125 immutability. (Dave Rolsky)
128 - Deprecated features have been moved to their own module,
129 Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)
131 0.92 Thu Aug 13, 2009
133 * Class::MOP::Package
134 - Move get_method_map and its various scaffolding into Package. (hdp)
137 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
138 the first argument, rather than just a coderef. (doy)
140 * Class::MOP::Attribute
142 - Allow attribute names to be false (while still requiring them to be
145 0.91 Wed Jul 29, 2009
146 * Class::MOP::Method::Wrapped
147 - Fixing variable usage issues with the patch from previous
148 version, not properly using lexicals in the for
151 0.90 Tue Jul 21, 2009
152 Japan Perl Association has sponsored Goro Fuji to improve startup
153 performance of Class::MOP and Moose. These enhancements may break
154 backwards compatibility if you're doing (or using) complex
155 metaprogramming, so, as always, test your code!
156 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
160 - Anonymous classes were not completely destroyed when they went
161 out of scope, leading to a memory leak. RT #47480. (Goro
165 - The get_method, has_method, and add_method methods no longer
166 use get_method_map. Method objects are instantiated
167 lazily. This significantly improves Class::MOP's load
171 - Inline fewer metaclass-level constructors since the ones we
172 have are perfectly fine. This reduces the number of string
175 * Class::MOP::Method::Wrapped
176 - If a method modifier set $_, this caused the modifier to blow
177 up, because of some weird internals. (Jeremy Stashewsky)
181 * Class::MOP::Class::Immutable::Trait
182 - Made the Trait act like a role with a bunch of "around"
183 modifiers, rather than sticking it in the inheritance
184 hierarchy. This fixes various problems that caused with
185 metaclass compatibility, which broke Fey::ORM.
188 - Allow a blessed code reference as the method body. Fixes a
189 problem interaction with MooseX::Types. (ash)
191 * Class::MOP::Instance
192 - add inline version of rebless_instance_structure. (doy)
193 - change inline_slot_access to use single quotes (gphat)
195 0.88 Tue, Jun 23, 2009
197 - Moved the __INSTANCE__ parameter to _construct_instance from
199 - Fixed some issues involving metaclasses of metaclasses and
202 0.87 Sun, Jun 21, 2009
204 - Made sure to always local-ize $@ and $SIG{__DIE__} before
205 calling an eval. Fixes RT #45973.
208 - Synced docs about immutability with the current reality (which
209 changed back in 0.82_01)
210 - Removed the immutable_transformer method, which had been
211 returning undef since 0.82_01 anyway.
214 - Got rid of tests which needed Moose and improved testing of
215 constructor/destructor inlining warnings. Fixes RT #47119.
217 0.86 Tue, Jun 16, 2009
219 - If you redefined a subroutine at runtime and then wrapped it
220 with a method modifier, the modifier could in some cases wrap
221 the original version of the subroutine. Fixes RT #46957.
224 - make_immutable issues a warning instead of overriding an
225 existing DESTROY method (Dylan William Hardison). Fixes RT
228 0.85 Sat, Jun 6, 2009
229 * Class::MOP::Attribute
230 - Allow default values to be Class::MOP::Methods. (Florian
232 - Test the above. (Rhesa Rozendaal)
233 - Tweak original commit so the intent matches the accepted
234 behavior (Nicholas Perez)
237 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
240 - Add direct_subclasses method (Sartak)
241 - Tests for subclasses and direct_subclasses (Sartak)
242 - subname is no longer used unconditionally in add_method, but
243 only if the code reference's name is '__ANON__' (nothingmuch)
244 - Add a hook for _superclasses_updated (Sartak)
247 - Remove long, old warning about possibly outdated modules
250 0.84 Tue, May 12, 2009
252 - Depend on Text::Exception 0.27 to avoid failing tests ond old
256 - Made is_class_loaded a little stricter. It was reporting that
257 a class was loaded if it merely had an @ISA variable in its
258 stash. Now it checks that the @ISA var has elements in it.
259 - Deprecate in_global_destruction and subname re-exporting
263 - Explicitly use Devel::GlobalDestruction and Sub::Name
266 * Class::MOP::Package
267 - Disable prototype mismatch warnings for add_package_symbol.
270 - Add test for finding methods from $meta->name->meta before immutable,
273 0.83 Mon, April 27, 2009
275 - Fix segfault when calling get_method_map on a metaclass for an empty
278 0.82_02 Fri, April 24, 2009
279 * Class::MOP::Method::Inlined
280 - Don't inline if the expected method is not defined at all (happens with
281 e.g. Moose::Object::_new is the expected method due to an overridden
284 - Some tests were trying to load Class::MOP::Immutable, which
285 was removed in 0.82_01.
287 0.82_01 Thu, April 23, 2009
288 * Class::MOP::Immutable (and others)
289 - Refactor the immutability system to use a pre-defined class
290 for the immutable metaclass of Class::MOP::Class::Immutable::$class
291 - Rather than generating methods into this class every time, use
292 a Trait (basic mixin) to supply the cached methods
293 - Remove the hack that returns the mutable metaclass for
294 metacircularity in order to provide consistent meta-metaclasses
295 for the Moose compatibility handling code
296 (mst broke it, nothingmuch fixed it)
298 0.82 Mon, April 20, 2009
300 - The deprecation wrappers for some renamed methods were not
301 passing arguments to the new method. (nothingmuch)
303 * Class::MOP::Immutable
304 - Warn during immutablization if the local class provides its own
305 constructor, to parallel the warning in Moose when a superclass
306 provides its own constructor (doy)
308 0.81 Tue, April 7, 2009
311 * Class::MOP::Instance
312 * Class::MOP::Attribute
313 * Class::MOP::Method::Accessor
314 * Class::MOP::Method::Constructor
315 - Include stack traces in the deprecation warnings introduced in
316 0.80_01. (Florian Ragwitz)
319 - Avoid c compiler warnings by declaring some unused function
320 arguments. (Florian Ragwitz)
322 0.80_01 Sun, April 5, 2009
324 - Make sure to preserve any compiler flags already defined in
325 Config.pm. Patch by Vincent Pit. RT #44739.
327 * Many methods have been renamed with a leading underscore, and a
328 few have been deprecated entirely. The methods with a leading
329 underscore are considered "internals only". People writing
330 subclasses or extensions to Class::MOP should feel free to
331 override them, but they are not for "public" use.
334 - construct_class_instance => _construct_class_instance (use new_object)
335 - construct_instance => _construct_instance (use new_object)
336 - check_metaclass_compatibility => _check_metaclass_compatibility
337 - create_meta_instance => _create_meta_instance (use get_meta_instance)
338 - clone_instance => _clone_instance (use clone_object)
339 - compute_all_applicable_methods is deprecated, use get_all_methods
340 - compute_all_applicable_attributes is deprecated, use get_all_attributes
342 - Class::MOP::Instance
343 - bless_instance_structure is deprecated and will be removed
347 - create has been renamed to _instantiate_module. This method
348 does not construct an object, it evals some code that
349 creates the relevant package in Perl's symbol table.
351 - Class::MOP::Method::Accessor
352 - initialize_body => _initialize_body (this is always called
353 when an object is constructed)
354 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
356 - Class::MOP::Method::Constructor
357 - initialize_body => _initialize_body (this is always called
358 when an object is constructed)
359 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
360 - attributes => _attributes
361 - meta_instance => _meta_instance
363 0.80 Wed, April 1, 2009
365 - Call user_class->meta in fewer places, with the eventual goal
366 of allowing the user to rename or exclude ->meta
367 altogether. Instead uses Class::MOP::class_of. (Sartak)
370 - New class_of function that should be used to retrieve a
371 metaclass. This is unlike get_metaclass_by_name in that it
372 accepts instances, not just class names. (Sartak)
375 - load_first_existing_class didn't actually load the first
376 existing class; instead, it loaded the first existing and
377 compiling class. It now throws an error if a class exists (in
378 @INC) but fails to compile. (hdp)
382 - we had some semi-buggy code that purported to provide a
383 HAS_ISAREV based on whether mro had get_isarev (due to an
384 oversight, it always returned 1). Since mro and MRO::Compat
385 have always had get_isarev, HAS_ISAREV was pointless. This
386 insight simplified the subclasses method by deleting the
387 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
389 0.79 Fri, March 29, 2009
390 * No changes from 0.78_02.
392 0.78_02 Thu, March 26, 2009
394 * Class::MOP::Immutable
395 - A big backwards-incompatible refactoring of the Immutable API,
396 and the make_immutable/make_mutable pieces of the Class
397 API. The core __PACKAGE__->meta->make_immutable API remains
398 the same, however, so this should only affect the most
402 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
403 has been fixed to be backwards compatible with 5.8.x.
406 - Add a hook for rebless_instance_away (Sartak)
407 - Use blessed instead of ref to get an instance's class name
408 in rebless_instance. (Sartak)
410 0.78_01 Wed, March 18, 2009
412 - Revised and reorganized all of the API documentation. All
413 classes now have (more or less) complete API documentation.
416 * Class::MOP::Instance
417 - Reblessing into a package that supports overloading wasn't
418 properly adding overload magic to the object due to a bug
419 in (at least) 5.8.8. We now use $_[1] directly which seems
420 to set the magic properly. (Sartak)
422 * Class::MOP::Attribute
423 - The process_accessors method is now private. A public alias
424 exists (and will stick around for a few releases), but it
425 warns that calling the public method is deprecated.
427 * Class::MOP::Method::Generated
428 - Removed the new and _new methods, since this is an abstract
429 base class, and all existing subclasses implement their own
433 - Stop is_class_loaded from thinking a class is loaded if it
434 only has an empty GV (Florian Ragwitz).
435 - Add a test for this (Yappo).
436 - Refactor get_all_package_symbols to allow short-circuiting
438 - Use this in is_class_loaded (Florian Ragwitz).
439 - Stop segfaulting when trying to get the name from a sub that's
440 still being compiled (Florian Ragwitz).
441 - Add tests for this (Florian Ragwitz).
442 - Prefix all public symbols with "mop_" (Florian Ragwitz).
443 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
444 - Simplify creating simple xs reader methods (Florian Ragwitz).
445 - Make everything compile with c++ compilers (Florian Ragwitz).
446 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
449 - Remove optional test plans for tests depending on Sub::Name as
450 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
453 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
455 0.78 Mon, February 23, 2009
456 * No changes from 0.77_01
458 0.77_01 Sun, February 22, 2009
460 - This package now requires its XS components. Not using
461 Sub::Name lead to different behavior and bugginess in the pure
462 Perl version of the code. A Moose test would fail when run
463 against the pure Perl version of this code.
465 * Class::MOP::Instance
466 - The inline_* methods now quote attribute names themselves, and
467 don't expect to receive a quoted value.
470 0.77 Sat, February 14, 2009
472 - Avoid assertion errors on debugging perls in is_class_loaded
476 - Fixed various corner cases where is_class_loaded incorrectly
477 returned true for a class that wasn't really loaded. (Dave
481 - Add get_all_method_names (Sartak)
482 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
484 * Class::MOP::Package
485 - Disable deprecated get_all_package_symbols in list
486 context. (Florian Ragwitz)
489 - Make sure we generate a BSD-compatible Makefile (Florian
493 - The misspelled "check_metaclass_compatability" method we've
494 kept around for backwards compat_i_bility will be removed in a
495 near future release. You've been warned.
497 0.76 Thu, January 22, 2009
498 * Class::MOP::Method::Generated
499 - Added new private methods to support code generation, which
500 are being used by Moose and can be used by MooseX
502 - Generated methods are now generated with a #line directive
503 reflecting the source of the generated method. (nothingmuch)
506 - Clarified documentation of methods that return
507 Class::MOP::Method objects. (doy)
510 - Clarified documentation of the metaclass cache methods. (Sartak)
513 - Add test showing how the xs Class::MOP::is_class_loaded can
514 be made to operate differently to the pure perl version (t0m)
516 0.75 Wed, December 31, 2008
518 - A class that was made immutable and then mutable could end up
519 sharing an immutable transformer object
520 (Class::MOP::Immutable) with other classes, leading to all
521 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
523 0.74 Tue, December 25, 2008
525 - Add an xs implementation of Class::MOP::is_class_loaded (closes
526 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
527 - Changed internals to make prehashing of hash keys easier and less
528 error-prone. (Florian Ragwitz)
530 - Fix documentation to show that around modifiers happen on both
531 sides of the modified method. (Dave Rolsky)
533 0.73 Tue, December 16, 2008
535 - Don't use Perl_mro_meta_init. It's not part of the public perl
536 api. Fixes failures to build on Win32 (RT #41750). (Florian
538 * t/082_get_code_info.t
539 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
540 munger anonymous subs when under -d and so making the tests
541 succeed in that case.
543 0.72 Mon, December 8, 2008
544 * Class::MOP::Package
545 - Pass options to _new, so subclass' attributes can be
548 - In the docs, indicate that package_name and name are required
549 when calling ->wrap (Stefan O'Rear)
551 0.71_02 Fri, December 5, 2008
552 * Class::MOP::Immutable
553 - Added a new attribute, inlined_constructor, which is true if
554 the constructor was inlined.
555 * Class::MOP::Package
556 - Make get_all_package_symbols return a hash ref in scalar
557 context and deprecate calling it in list context with a
558 warning. (Florian Ragwitz)
560 - Various improvements and refactoring, making things more robust and
561 easier to maintain. (Florian Ragwitz)
563 0.71_01 Wed, December 3, 2008
565 - Add an "execute" method to invoke the body so
566 we can avoid using the coderef overload (Sartak)
567 * Class::MOP::Immutable
568 - When we memoize methods, get their results lazily
569 to remove some compile-time cost (Sartak)
570 - Small speedup from eliminating several method
573 - Some small internal tweaks to try to reduce the number of
574 times we call get_method_map when bootstrapping the MOP. This
575 might make loading Class::MOP (and Moose) a little
576 faster. (Dave Rolsky)
577 - Implemented an optional XS version of get_method_map. Mostly
578 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
579 help form Florian Ragwitz. (Dave Rolsky)
580 - Make the behaviour of of get_all_package_symbols (and
581 therefore get_method_map) consistent for stub methods. Report
582 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
584 0.71 Wed November 26, 2008
587 - Actual package creation has moved upward from
588 Class to Module so that Moose roles can share
591 0.70_01 Mon, November 19, 2008
593 - Fixes for failures with blead (Florian Ragwitz)
594 - Silenced compiler warnings (Florian Ragwitz)
596 0.70 Fri, November 14, 2008
598 - Fixed an odd corner case where the XS version of
599 get_all_package_symbols could cause a segfault. This only
600 happened with inlined constants in Perl 5.10.0 (Florian
603 0.69 Fri, November 7, 2008
604 * Class::MOP::Method::Wrapped
605 - Added introspection methods for method modifiers (Dave Rolsky)
608 0.68 Fri October 24, 2008
610 - Make load_class require by file name instead of module name.
611 This stops confusing error messages when loading '__PACKAGE__'.
613 - Add load_one_class_of function to enable you to load one of a
614 list of classes, rather than having to call load_class multiple
615 times in an eval. (t0m)
617 0.67 Tue October 14, 2008
619 - Call a method on the class after setting the superclass list
620 so that we can get Perl to detect cycles before MRO::Compat
621 spirals into an infinite loop (sartak)
622 - Reported by Schwern, [rt.cpan.org #39001]
623 - In create(), pass unused options on to initialize()
624 - added test for this
626 0.66 Sat September 20, 2008
627 !! This release has an incompatible change regarding !!
628 introspection of a class's method with Class::MOP::Class !!
631 - We (us maintainers) now run all tests with XS and then without
632 XS, which should help us catch skew between the XS/pure Perl
636 ! The alias_method method has been deprecated. It now simply
637 calls add_method instead. There is no distinction between
638 aliased methods and "real" methods.
640 This means that methods added via alias_method now show up as
641 part of the class's method list/map. This is a backwards
642 incompatible change, but seems unlikely to break any
643 code. Famous last words. (Dave Rolsky)
646 - Fixed the spelling of "compatibility", but we still have a
647 "check_metaclass_compatability" method for backwards
650 0.65 Mon September 1, 2008
651 For those not following the series of dev releases, the changes
652 from 0.64 from 0.65 can mostly be summed up as a lot performance
653 improvements by nothingmuch, including new optional XS versions of
654 some methods. Also, Class::MOP now works _without_ any XS modules,
655 for sad systems without a compiler.
658 - Added name and package_name XS accessors, and make sure all
659 the XS and Perl versions work the same way. (Dave Rolsky)
662 - The XS versions of various methods just returned undef when
663 called class methods, rather than dying like the pure Perl
664 versions. (Dave Rolsky)
666 0.64_07 Fri August 29, 2008
668 - Silenced warnings that managed to break Moose tests when XS
669 was loaded. (Dave Rolsky)
670 - Some XS versions of methods were ignored because of typos in
671 MOP.xs. (Dave Rolsky)
673 0.64_06 Mon August 25, 2008
674 * Class::MOP (MOP.xs)
675 - Another MS VC++ fix, cannot declare a variable in the middle
676 of a scope (Taro Nishino).
678 0.64_05 Sun August 24, 2008
680 - None of the dev releases actually loaded the XS properly, but
681 we silently fell back to the pure Perl version of the
684 * Class::MOP (MOP.xs)
685 - Replaced some code that used functions not available on Visual
686 C++ with some Perl XS API bits (Dave Rolsky).
688 0.64_04 Sat August 23, 2008
690 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
692 * pod.t and pod_coveraget.t
693 - These are no longer shipped with the tarball because of bogus
694 failures from CPAN testers. (Dave Rolsky)
696 0.64_03 Thu August 21, 2008
697 * Class::MOP::Package
698 - Some (legit) code was misparsed by earlier 5.8.x
699 releases. (nothingmuch)
702 - Fix a constant in void context warning (nothingmuch)
704 0.64_02 Thu August 21, 2008
705 * Makefile.PL and Class::MOP
706 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
709 - Add missing prereqs that got lost in the switch away from
712 * Class::MOP::Instance
713 - New method - get_all_attributes (nothingmuch)
715 0.64_01 Wed August 20, 2008
717 - We now check to see if you have a compiler. If you don't, the
718 module installs without some XS bits, but will work the same
719 as with XS. This should make it easier to install on platforms
720 without a compiler (like Windows). (Dave Rolsky)
723 - Perl 6 style attribute naming replaced with sane style ('methods', not
724 '%!methods'). These changes should not impact any existing API uses.
728 - Quite a number of optimizations based on profiling, including
729 allowing constructors to take hash references instead of
730 hashes, duplicating some frequently used code in XS, and
731 making constructors immutable. These changes should not impact
732 any existing API uses. (nothingmuch)
735 - Constructors now respect the meta attributes of their subclasses,
736 facilitating MOP extensibility. More related changes will happen in the
737 next several releases. (nothingmuch)
740 - New method - get_all_methods, replaces the deprecated
741 compute_all_applicable_methods. get_all_attributes provided for
742 consistency (nothingmuch)
743 - New method - wrap_method was refactored out of get_method_map
745 - New API for meta instance invalidation - invalidate_meta_instance,
746 invalidate_meta_instances, add_dependent_meta_instance,
747 remove_dependent_meta_instance, called automatically when attribute
748 definitions change and allows notification of dependent subclasses.
751 0.64 Sun August 3, 2008
752 * Class::MOP::Immutable
753 - fixing subtle edge case in immutable when you
755 - clean up option processing (nothingmuch)
757 * Class::MOP::Instance
758 - inlined initialize slot didn't match
759 non-inlined (nothingmuch)
761 0.63 Mon July 7, 2008
763 - load_class will initialize a metaclass even if
764 the class is already loaded (sartak)
765 - load_class now returns the metaclass instance
766 instead of just 1 (sartak)
769 - better error messages (sartak and Dave Rolsky)
771 0.62 Wed June 18, 2008
772 - in is_class_loaded, recognize scalar references (as opposed to globs) in
773 the symbol table as methods (these are optimized constant subs)
775 0.61 Fri. June 13, 2008
776 - Okay, lets give this another try and see if PAUSE
777 recognizes it correct this time.
779 0.60 Thurs. Jun 12, 2008
780 - Fixed a version number issue by bumping all modules
783 0.59 Thurs. Jun 12, 2008
784 !! Several fixes resulting in yet another 25-30% speedup !!
787 - now stores the instance of the instance
788 metaclass to avoid needless recomputation
789 and deletes it when the cache is blown
790 - introduce methods to query Class::MOP::Class for
791 the options used to make it immutable as well as
792 the proper immutable transformer. (groditi)
794 * Class::MOP::Package
795 - {add, has, get, remove}_package_symbol all
796 now accept a HASH ref argument as well as the
797 string. All internal usages now use the HASH
801 - MOP.xs does sanity checks on the coderef
803 - is_class_loaded check now uses code that
804 was improved in Moose's ClassName type
806 - nonsensical (undef, empty, reference) class
807 names now throw a more direct error in
809 - tests for this and other aspects of
815 Class::MOP::Method::Wrapped
816 Class::MOP::Attribute
817 - switched usage of reftype to ref because
820 0.58 Thurs. May 29, 2008
821 (late night release engineering)--
823 - fixing the version is META.yml, no functional
824 changes in this release
826 0.57 Wed. May 28, 2008
827 !! Several speedups resulting in 20-25% speedups !!
828 || (thanks to konobi, groditi, mst & CataMoose) !!
831 - made get_method_map use list_all_package_symbols
832 instead of manually grabbing each symbol
833 - streamlining &initialize somewhat, since it gets
836 * Class::MOP::Package
837 - made {get, has}_package_symbol not call
839 - inlining a few calls to &name with
840 direct HASH access key access
841 - added get_all_package_symbols to fetch
842 a HASH of items based on a type filter
843 similar to list_all_package_symbols
844 - added tests for this
847 Class::MOP::Method::Constructor
848 Class::MOP::Method::Generated
849 Class::MOP::Method::Accessor
850 - added more descriptive error message to help
851 keep people from wasting time tracking an error
852 that is easily fixed by upgrading.
854 * Class::MOP::Immutable
855 - Don't inline a destructor unless the user actually
857 - added tests for this
859 0.56 Saturday, May 24, 2008
861 - we now get the &check_package_cache_flag
862 function from MRO::Compat
863 - All XS based functionality now has a
864 Pure Perl alternative
865 - the CLASS_MOP_NO_XS environment variable
866 can now be used to force non-XS versions

876 * Class::MOP::Immutable
877 - added the ability to "wrap" methods when
878 making the class immutable

883 allow for it to work.
884 - added tests for this
886 * Class::MOP::Attribute
888 Class::MOP::Immutable
889 - any time a method meta object is constructed
890 we make sure to pass the correct package and
891 method name information
894 Class::MOP::Method::Wrapped
895 Class::MOP::Method::Generated
896 Class::MOP::Method::Accessor
897 Class::MOP::Method::Consructor
898 - the &wrap constructor method now requires that a
899 'package_name' and 'name' attribute are passed. This
900 is to help support the no-XS version, and will
901 throw an error if these are not supplied.
902 - all these classes are now bootstrapped properly
903 and now store the package_name and name attributes
906 ~ Build.PL has been removed since the
907 Module::Install support has been removed
909 0.55 Mon. April 28, 2008
910 - All classes now have proper C3 MRO support
911 - added MRO::Compat as a dependency to allow
912 for the C3 MRO support to Just Work in all
916 - rebless_instance now returns the instance
917 it has just blessed, this is mostly to
919 - set the attr correctly in rebless_instance
920 when it has no init_arg
921 - tweaked &linear_isa and &class_precedence_list
922 to support c3 classes.
924 0.54 Fri. March, 14, 2008
927 - making sure that load_class never gets
928 passed a value from @_ or $_ to squash
929 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
932 - make_{immutable,mutable} now return 1
934 - improved error handling in ->create method
935 - rebless_instance now takes extra params which
936 will be used to populate values
937 - added tests for this
940 - localizing the Data::Dumper configurations so
941 that it does not pollute others (RT #33509)
947 Class::MOP::Attribute
948 - these classes no longer define their own ->meta,
949 but instead just inherit from Class::MOP::Object
951 * Class::MOP::Instance
952 Class::MOP::Immutable
953 - these classes now inherit from Class::MOP::Object
956 - fixed the filename length on several
957 test files so we install on VMS better
959 - fixed incorrect use of catdir when it
960 should be catfile (RT #32385)
962 0.53 Thurs. Feb. 14, 1008
963 ~~ several doc. fixes and updates ~~
966 Class::MOP::Method::Constructor
967 Class::MOP::Attribute
968 - making init_arg accept an undefined value
969 to indicate that no constructor args can
970 be passed (thanks to nothingmuch)
971 - added tests for this
972 - added attribute initializer attribute (rjbs)
975 - making this use the new init_arg => undef
976 feature instead of the silly hack from
977 before (thanks to nothingmuch)
979 0.52 Tues. Jan. 22, 2008
981 - fixed bug in rebless_instance
984 * Class::MOP::Method::Constructor
985 - removed assumptions about the existence of
988 0.51 Mon. Jan. 14, 2008
989 ~~~ some misc. doc. fixes ~~~
990 ~~ updated copyright dates ~~
993 - now sets the IS_RUNNING_ON_5_10
994 constant so that we can take advantage
995 of some of the nice bits of 5.10
998 - uses the IS_RUNNING_ON_5_10 flag to
999 optimize the &linearized_isa method
1000 and avoid the hack/check for circular
1001 inheritence in &class_precedence_list
1002 - added rebless_instance method (Sartak)
1003 - added tests for this
1005 * Class::MOP::Immutable
1006 - the immutable class now keeps track of
1007 the transformer which immutablized it
1009 * Class::MOP::Instance
1010 - added rebless_instance_structure method (Sartak)
1011 - added tests for this
1013 0.50 Fri. Dec. 21, 2007
1015 - fixed bug in immutable to make sure that
1016 transformation arguments are saved
1018 - added tests for this
1020 * Class::MOP::Immutable
1021 - fixed a bug (see above)
1023 * Class::MOP::Attribute
1026 0.49 Fri. Dec. 14, 2007
1027 !! Class::MOP now loads 2 x faster !!
1028 !! with XS speedups (thanks konobi) !!
1031 - removed the dependency on B
1032 - added two XS functions (thanks konobi)
1033 - get_code_info($code) which replaces all
1034 the B fiddling we were doing with
1035 faster/leaner XS level fiddling
1036 - check_package_cache_flag($pkg_name) which
1037 returns the PL_sub_generation variable to
1038 be used to help manage method caching.
1041 In 5.10 or greater this will actually
1042 use the mro::get_pkg_gen instead to give
1043 even more accurate caching information.
1044 blblack++ for that stuff :)
1047 - added the &subclasses method (thanks rlb)
1048 - added the update_package_cache_flag and
1049 reset_package_cache_flag which help keep
1050 track of when we need to re-fetch the
1052 - Several small improvements to take advantage
1053 of the new method map caching features
1055 0.48 Mon. Nov. 26, 2007
1056 * Class::MOP::Attribute
1057 - fixed get_read/write_method to handle the
1058 HASH ref case, which makes the
1059 get_read/write_method_ref handle it too.
1060 - added more tests for this
1062 0.47 Sat. Nov. 24, 2007
1063 * Class::MOP::Attribute
1064 - fixed misspelling in get_write_method_ref
1065 - added more tests for this
1067 0.46 Fri. Nov. 23, 2007
1069 - added the linearized_isa method instead of constantly
1070 pruning duplicate classes (this will be even more
1071 useful in the 5.10-compat version coming soon)
1073 * Class::MOP::Attribute
1074 - added the get_read_method_ref and get_write_method_ref
1075 methods which allow you to retrieve a CODE ref which
1076 can always be used to read or write an attribute.
1078 0.45 Thurs. Nov. 13, 2007
1079 * Class::MOP::Attribute
1080 - Fix error message on confess (groditi)
1082 0.44 Thurs. Nov. 13, 2007

1085 0.43 Thurs. Nov. 13, 2007
1087 - Add support for the 'builder' attribute (groditi)
1090 - optimise metaclass-already-exists check in
1091 construct_class_instance (groditi)
1092 - duplicate check into initialize to save a
1093 call through (groditi)
1095 * Class::MOP::Attribute
1096 - Add support for the 'builder' attribute (groditi)
1097 - Make predicates check for the existence of a value, not whether
1098 it is defined (groditi)
1100 * Class::MOP::Instance
1101 - Make predicates check for the existence of a value, not whether
1102 it is defined (groditi)
1104 * Class::MOP::Method::Accessor
1105 - made this a subclass of Class::MOP::Method::Generated
1106 - removed the relevant attributes
1108 * Class::MOP::Method::Constructor
1109 - fixed the cached values we had to be more sane
1110 - made this a subclass of Class::MOP::Method::Generated
1111 - fixed generated constructor so it properly handles
1113 - added tests for this
1114 - added the option to allow for both inlined and
1115 non-inlined constructors.
1116 - Update inlined methods for builder and predicate changes (groditi)
1118 * Class::MOP::Method::Generated
1119 - added this class as an abstract base for the
1120 Class::MOP::Method::{Constructor,Accessor} classes
1121 - added tests for this
1124 - Alter tests (005, 014 020, 021) for new builder addition (groditi)
1125 - Tests for new predicate behavior (and corrections to old tests) (groditi)
1128 - Update ArrayRef based class example to work with predicate changes
1130 0.42 Mon. July 16, 2007
1131 !!! Horray for mst, he fixed it !!!
1133 * Class::MOP::Package
1134 - alter symbol table handling to deal with 5.8.x and 5.9.x
1137 - Get rid of the crappy workaround from 0.40/41
1139 0.41 Sun. July 15, 2007
1141 Arghh!!! My TODO test didn't work, so I handle
1142 it manually now so that people can use this
1143 with 5.9.5/bleadperl without issue.
1145 0.40 Tues, July 3, 2007
1147 ~ marked a test in 003_methods.t as TODO
1148 for perl 5.9.5 (this test is irrelvant to
1149 the module functioning on 5.9.5 for the most
1152 0.39 Mon. June 18, 2007
1153 * Class::MOP::Immutable
1154 - added make_metaclass_mutable + docs (groditi)
1155 - removed unused variable
1156 - added create_immutable_transformer
1157 necessary for sane overloading of immutable behavior
1158 - tests for this (groditi)
1161 - Immutability can now be undone,
1162 added make_mutable + tests + docs (groditi)
1163 - Massive changes to the way Immutable is done
1164 for details see comments next to make_immutable
1165 This fixes a bug where custom metaclasses broke
1166 when made immutable. We are now keeping one immutable
1167 metaclass instance per metaclass instead of just one
1168 to prevent isa hierarchy corruption. Memory use will go
1169 up, but I suspect it will be neglible.
1170 - New tests added for this behavior. (groditi)
1172 0.38 Thurs. May 31, 2007
1173 ~~ More documentation updates ~~
1175 * Class::MOP::Package
1176 - we now deal with stub methods properly

1181 - added get_read_method and get_write_method
1182 thanks to groditi for this code, tests
1184 - added tests and POD for this
1187 - fixed RT issue #27329, clone object now
1188 handles undef values correctly.
1189 - added tests for this
1190 - Corrected anon-class handling so that they
1191 will not get reaped when instances still
1192 exist which need to reference them. This is
1193 the correct behavior, hopefully this is an
1194 obscure enough feature that there are not too
1195 many work arounds out in the wild.
1196 - added tests for this by groditi
1197 - updated docs to explain this
1200 - load custom metaclasses automatically (thanks groditi)
1201 - added tests for this behavior
1203 0.37 Sat. March 10, 2007
1204 ~~ Many, many documentation updates ~~
1207 - added &load_class and &is_class_loaded
1208 - added tests and docs for these
1210 * Class::MOP::Attribute
1211 - default now checks the instance with defined to
1212 avoid setting off bool-overloads (found by Carl Franks)
1216 - bad name in a test, causing meaningless failuress.
1221 ~~ GLOBAL CHANGES ~~
1222 - All attribute names are now consistent and follow Perl 6
1223 style (prefixed with the sigil, and ! as the twigil for
1224 private attrs). This should not affect any code, unless
1225 you broke encapsulation, in which case, it is your problem
1228 !! Class::MOP::Class::Immutable has been removed
1230 * Class::MOP::Method::Constructor
1231 - this has been moved out of Class::MOP::Class::Immutable
1232 and is a proper subclass of Class::MOP::Method now.
1235 - this module now uses Class::MOP::Immutable for the
1236 immutable transformation instead of
1237 Class::MOP::Class::Immutable.
1239 + Class::MOP::Immutable
1240 - this module now controls the transformation from a mutable
1241 to an immutable version of the class. Docs for this will
1242 be coming eventually.
1245 0.36 Sun. Nov. 5, 2006
1247 - added a few 'no warnings' lines to keep annoying
1248 (and meaningless) warnings from chirping during
1252 - some more bootstrapping is now done on the new
1255 * Class::MOP::Class::Immutable
1257 - constructor generation is now handled by
1258 the Class::MOP::Method::Constructor class
1260 * Class::MOP::Method::Constructor
1261 - created this to handle constructor generation
1262 in Class::MOP::Class::Immutable
1264 * Class::MOP::Attribute
1266 - attributes now delegate to the
1267 Class::MOP::Method::Accessor to generate
1270 * Class::MOP::Method::Accessor
1271 - all accessor generation functions from
1272 Class::MOP::Attribute have been moved here
1274 0.35 Sat. Sept. 30, 2006

1277 - initial prototype of a class browser, more
1278 on this to come. Comments and patches are
1282 - All Class::MOP::* accessors are no longer
1283 re-generated in the bootstrap, instead
1284 they are aliased from the originals
1285 - fixed tests to reflect
1286 - added Class::MOP::Method (and its subclasses)
1288 - adjusted tests for this
1289 - added the Class::MOP::Instance attributes
1292 * Class::MOP::Method
1294 - methods are no longer blessed CODE refs
1295 but are actual objects which can be CODE-ified
1296 - adjusted tests to compensate
1297 - adjusted docs for this
1300 - changed how methods are dealt with to
1301 encapsulate most of the work into the
1302 &get_method_map method
1303 - made several adjustments for the change
1304 in Class::MOP::Method
1305 - &add_attribute now checks if you are adding
1306 a duplicate name, and properly removes the
1307 old one before installing the new one
1308 - added tests for this
1309 - adjusted docs for this
1311 * Class::MOP::Class::Immutable
1312 - added caching of &get_method_map
1313 - fixed issue with &get_package_symbol
1314 - cleaned up the methods that die (patch by David Wheeler)

1317 - added filtering capabilities to
1318 &list_all_package_symbols
1320 0.34 Sat. Aug. 26, 2006
1322 - added the %:methods attribute, which like
1323 the $:version and such just actually goes
1324 to the symbol table to get it's stuff.
1325 However, it makes the MOP more complete.
1327 - The &create method now requires that all
1328 but the package name now is passed in as
1329 named parameters. See docs for more info.
1330 - updated docs and tests for this
1332 * Class::MOP::Object
1333 - added &dump method to easily Data::Dumper

1354 - reference values (other than CODE refs)
1355 are no longer allowed for defaults
1356 - added tests for this
1358 * Class::MOP::Package
1359 - fixed an issue with perl 5.8.1 and how it deals
1360 with symbol tables. The namespace hash is now
1361 always reloaded from the symbol table.
1363 ~ lots of misc. documentation cleanup
1365 0.32 Sat. Aug. 12, 2006
1366 + added Class::MOP::Object so that the
1367 metamodel is more complete (and closer
1368 to what Perl 6 will probably be).
1370 * Class::MOP::Package
1371 - refactored entire class, this is now
1372 the primary gateway between the metaclass
1373 and the Perl 5 symbol table
1374 - added many tests for this
1375 - this class is now a subclass of
1377 - added some tests to reflect this
1380 - refactored all symbol table access to
1381 use Class::MOP::Package methods instead
1383 * Class::MOP::Module
1384 - adding the $:version attribute in the bootstrap
1385 so that Module has a version as an attribute
1386 - see comment in Class::MOP for details
1387 - added the $:authority attribute to this module
1388 as well as an &identifier method, to bring us
1389 ever closer to Perl 6 goodness

1407 anywhere within the class hierarchy
1409 * Class::MOP::Attribute
1410 - added &set_value and &get_value for getting
1411 the value of the attribute for a particular
1414 0.30 Wed. July 5, 2006
1415 ---------------------------------------
1416 This is the first version of Class::MOP
1417 to introduce the immutable features which
1418 will be used for optimizating the MOP.
1419 This support should still be considered
1420 experimental, but moving towards stability.
1421 ---------------------------------------
1423 * Created Class::MOP::Class::Immutable
1425 * Created the Class::MOP::Package and
1426 Class::MOP::Module classes to more
1427 closely conform to Perl 6's meta-model
1430 - now inherits from Class::MOP::Module
1431 - several methods moved to ::Module and
1432 ::Package and now inherited
1433 - added tests for this
1435 * Class::MOP::Instance
1436 - added an is_inlinable method to allow other
1437 classes to check before they attempt to optimize.
1438 - added an inline_create_instance to inline
1439 instance creation (of course)
1442 - the Class::MOP::Class::*_package_variable
1443 methods are all now methods of Class::MOP::Package
1444 and called *_package_symbol instead. This is
1445 because they are now more general purpose symbol
1446 table manipulation methods.
1448 0.29_02 Thurs. June 22, 2006
1449 ++ DEVELOPER RELEASE ++
1451 - small change in &create so that it behaves
1452 properly when inherited
1453 - small fix to &clone_instance
1455 0.29_01 Fri. May 12, 2006
1456 ++ DEVELOPER RELEASE ++
1457 - This release works in combination with
1458 Moose 0.09_01, it is a developer release
1459 because it introduces a new instance
1460 sub-protocol and has not yet been
1464 - anon-classes are now properly garbage collected
1465 - added tests for this
1466 - improved method modifier wrapping
1468 * Class::MOP::Instance
1469 - added new instance protocol
1470 - added tests for this
1471 - changed all relevant modules and examples
1473 - Class::MOP::Attribute
1477 - you no longer need to specify the metaclass
1478 itself, if it is not there, Class::MOP::Class
1480 - updated tests for this
1483 - added ArrayBasedStorage example to show
1484 instance storage using ARRAY refs instead of
1486 - added tests for this
1487 - InsideOutClass is totally revised using the
1488 new instance protocol

1503 - added tests for this
1504 - added get_all_metaclasses, get_all_metaclass_names
1505 and get_all_metaclass_instances method to allow
1506 access to all the cached metaclass objects.
1507 - attribute slot initialization is now the responsibility
1508 of the attribute itself, and construct_instance now
1509 delegates appropriately
1511 * Class::MOP::Attribute
1512 - attribute slot initialization is now the responsibility
1513 of the attribute itself, so we added a method for it
1514 called initialize_instance_slot
1517 - adjusted all the examples to use the new attribute
1518 initialize_instance_slot method
1520 0.24 Tues. April 11, 2006

1541 - added test case for this
1543 0.21 Wed. March 15, 2006
1545 - fixed issue where metaclasses are reaped from
1546 our cache in global destruction, and so are not
1547 available in DESTORY calls
1549 0.20 Thurs. March 2, 2006
1550 - removed the dependency for Clone since
1551 we no longer to deep-cloning by default.
1553 * Class::MOP::Method
1554 - added &package_name, &name and
1555 &fully_qualified_name methods, some of
1556 which were formerly private subs in
1559 * Class::MOP::Method::Wrapped
1560 - allows for a method to be wrapped with
1561 before, after and around modifiers
1562 - added tests and docs for this feature
1565 - improved &get_package_symbol
1566 - &version and &superclasses now use it
1567 - methods are now blessed into Class::MOP::Method

1572 - &add_around_method_modifier
1573 - added tests and docs for these

1577 0.12 Thurs. Feb 23, 2006
1578 - reduced the dependency on B, no need to always
1582 - added docs to the C3 method dispatch order test
1583 - fixed missing Algorithm::C3 dependency by making
1584 the test skip if it is not installed
1586 0.11 Mon Feb. 20, 2006
1588 - added example of changing method dispatch order to C3
1591 - changed how clone_instance behaves, it now only does a
1592 shallow clone (see docs for more details)
1593 - added docs and tests
1595 0.10 Tues Feb. 14, 2006
1596 ** This release was mostly about writing more tests and
1597 cleaning out old and dusty code, the MOP should now
1598 be considered "ready to use".
1600 - adding more tests to get coverage up a little higher,
1601 mostly testing errors and edge cases.
1602 - test coverage is now at 99%
1605 - no longer optionally exports to UNIVERSAL::meta or
1606 creates a custom metaclass generator, use the
1607 metaclass pragma instead.
1610 - fixed a number of minor issues which came up in the
1611 error/edge-case tests
1613 * Class::MOP::Attribute
1614 - fixed a number of minor issues which came up in the

1620 0.06 Thurs Feb. 9, 2006
1622 - adding new metaclass pragma to make setting up the
1623 metaclass a little more straightforward
1626 - clean up bootstrapping to include more complete
1627 attribute definitions for Class::MOP::Class and
1628 Class::MOP::Attribute (accessors, readers, writers,
1629 etc.) ... it is redundant, but is useful meta-info
1633 - fixing minor meta-circularity issue with &meta, it
1634 is now more useful for subclasses
1635 - added &get_attribute_map as an accessor for the
1636 hash of attribute meta objects
1637 - &compute_all_applicable_attributes now just returns
1638 the attribute meta-object, rather than the HASH ref
1639 since all the same info can be gotten from the
1640 attribute meta-object itself
1641 - updated docs & tests to reflect
1642 - added &clone_instance method which does a deep clone
1643 of the instance structure created by &construct_instance
1644 - added docs & tests for this
1645 - added Clone as a dependency

1647 return blessed new or cloned instances
1648 - they handle Class::MOP::Class singletons correctly too
1649 - added docs & tests for this
1650 - cleaned up the &constuct_class_instance so that it behaves
1651 more like &construct_instance (and managed the singletons too)
1652 - added the &check_metaclass_compatibility method to make sure
1653 that metaclasses are upward and downward compatible.
1654 - added tests and docs for this
1657 - adjusting code to use the &Class::MOP::Class::meta
1659 - adjusting code to use the metaclass pragma
1661 0.05 Sat Feb. 4, 2006
1663 - added the &attribute_metaclass and &method_metaclass
1664 attributes which contain a metaclass name to use for
1665 attributes/methods respectively
1668 - bootstrap additional attributes for Class::MOP::Class
1671 - adjusted the example code and tests to use the new
1672 &attribute_metaclass feature of Class::MOP::Class
1673 - added new example:
1676 0.04 Fri Feb. 3, 2006
1678 - some documentation suggestions from #perl6

1703 - moving examples from t/lib/* to examples/*
1704 - adding POD documentation to the examples
