1 Revision history for Perl extension Class-MOP.
5 - Implement all the MOP accessors in XS (gfx)
6 - Implement accessor and constructor generators in XS (gfx)
8 - Accessor methods are now created once, so make_immutable() can
9 generate constructors and destructores (gfx)
10 It is already true in Moose, but was not in Class::MOP
15 - Move get_method_map and its various scaffolding into Package. (hdp)
18 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
19 the first argument, rather than just a coderef. (doy)
21 * Class::MOP::Attribute
23 - Allow attribute names to be false (while still requiring them to be
27 * Class::MOP::Method::Wrapped
28 - Fixing variable usage issues with the patch from previous
29 version, not properly using lexicals in the for
33 Japan Perl Association has sponsored Goro Fuji to improve startup
34 performance of Class::MOP and Moose. These enhancements may break
35 backwards compatibility if you're doing (or using) complex
36 metaprogramming, so, as always, test your code!
37 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
41 - Anonymous classes were not completely destroyed when they went
42 out of scope, leading to a memory leak. RT #47480. (Goro
46 - The get_method, has_method, and add_method methods no longer
47 use get_method_map. Method objects are instantiated
48 lazily. This significantly improves Class::MOP's load
52 - Inline fewer metaclass-level constructors since the ones we
53 have are perfectly fine. This reduces the number of string
56 * Class::MOP::Method::Wrapped
57 - If a method modifier set $_, this caused the modifier to blow
58 up, because of some weird internals. (Jeremy Stashewsky)
62 * Class::MOP::Class::Immutable::Trait
63 - Made the Trait act like a role with a bunch of "around"
64 modifiers, rather than sticking it in the inheritance
65 hierarchy. This fixes various problems that caused with
66 metaclass compatibility, which broke Fey::ORM.
69 - Allow a blessed code reference as the method body. Fixes a
70 problem interaction with MooseX::Types. (ash)
72 * Class::MOP::Instance
73 - add inline version of rebless_instance_structure. (doy)
74 - change inline_slot_access to use single quotes (gphat)
76 0.88 Tue, Jun 23, 2009
78 - Moved the __INSTANCE__ parameter to _construct_instance from
80 - Fixed some issues involving metaclasses of metaclasses and
83 0.87 Sun, Jun 21, 2009
85 - Made sure to always local-ize $@ and $SIG{__DIE__} before
86 calling an eval. Fixes RT #45973.
89 - Synced docs about immutability with the current reality (which
90 changed back in 0.82_01)
91 - Removed the immutable_transformer method, which had been
92 returning undef since 0.82_01 anyway.
95 - Got rid of tests which needed Moose and improved testing of
96 constructor/destructor inlining warnings. Fixes RT #47119.
98 0.86 Tue, Jun 16, 2009
100 - If you redefined a subroutine at runtime and then wrapped it
101 with a method modifier, the modifier could in some cases wrap
102 the original version of the subroutine. Fixes RT #46957.
105 - make_immutable issues a warning instead of overriding an
106 existing DESTROY method (Dylan William Hardison). Fixes RT
109 0.85 Sat, Jun 6, 2009
110 * Class::MOP::Attribute
111 - Allow default values to be Class::MOP::Methods. (Florian
113 - Test the above. (Rhesa Rozendaal)
114 - Tweak original commit so the intent matches the accepted
115 behavior (Nicholas Perez)
118 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
121 - Add direct_subclasses method (Sartak)
122 - Tests for subclasses and direct_subclasses (Sartak)
123 - subname is no longer used unconditionally in add_method, but
124 only if the code reference's name is '__ANON__' (nothingmuch)
125 - Add a hook for _superclasses_updated (Sartak)
128 - Remove long, old warning about possibly outdated modules
131 0.84 Tue, May 12, 2009
133 - Depend on Text::Exception 0.27 to avoid failing tests ond old
137 - Made is_class_loaded a little stricter. It was reporting that
138 a class was loaded if it merely had an @ISA variable in its
139 stash. Now it checks that the @ISA var has elements in it.
140 - Deprecate in_global_destruction and subname re-exporting
144 - Explicitly use Devel::GlobalDestruction and Sub::Name
147 * Class::MOP::Package
148 - Disable prototype mismatch warnings for add_package_symbol.
151 - Add test for finding methods from $meta->name->meta before immutable,
154 0.83 Mon, April 27, 2009
156 - Fix segfault when calling get_method_map on a metaclass for an empty
159 0.82_02 Fri, April 24, 2009
160 * Class::MOP::Method::Inlined
161 - Don't inline if the expected method is not defined at all (happens with
162 e.g. Moose::Object::_new is the expected method due to an overridden
165 - Some tests were trying to load Class::MOP::Immutable, which
166 was removed in 0.82_01.
168 0.82_01 Thu, April 23, 2009
169 * Class::MOP::Immutable (and others)
170 - Refactor the immutability system to use a pre-defined class
171 for the immutable metaclass of Class::MOP::Class::Immutable::$class
172 - Rather than generating methods into this class every time, use
173 a Trait (basic mixin) to supply the cached methods
174 - Remove the hack that returns the mutable metaclass for
175 metacircularity in order to provide consistent meta-metaclasses
176 for the Moose compatibility handling code
177 (mst broke it, nothingmuch fixed it)
179 0.82 Mon, April 20, 2009
181 - The deprecation wrappers for some renamed methods were not
182 passing arguments to the new method. (nothingmuch)
184 * Class::MOP::Immutable
185 - Warn during immutablization if the local class provides its own
186 constructor, to parallel the warning in Moose when a superclass
187 provides its own constructor (doy)
189 0.81 Tue, April 7, 2009
192 * Class::MOP::Instance
193 * Class::MOP::Attribute
194 * Class::MOP::Method::Accessor
195 * Class::MOP::Method::Constructor
196 - Include stack traces in the deprecation warnings introduced in
197 0.80_01. (Florian Ragwitz)
200 - Avoid c compiler warnings by declaring some unused function
201 arguments. (Florian Ragwitz)
203 0.80_01 Sun, April 5, 2009
205 - Make sure to preserve any compiler flags already defined in
206 Config.pm. Patch by Vincent Pit. RT #44739.
208 * Many methods have been renamed with a leading underscore, and a
209 few have been deprecated entirely. The methods with a leading
210 underscore are consider "internals only". People writing
211 subclasses or extensions to Class::MOP should feel free to
212 override them, but they are not for "public" use.
215 - construct_class_instance => _construct_class_instance (use new_object)
216 - construct_instance => _construct_instance (use new_object)
217 - check_metaclass_compatibility => _check_metaclass_compatibility
218 - create_meta_instance => _create_meta_instance (use get_meta_instance)
219 - clone_instance => _clone_instance (use clone_object)
220 - compute_all_applicable_methods is deprecated, use get_all_methods
221 - compute_all_applicable_attributes is deprecated, use get_all_attributes
223 - Class::MOP::Instance
224 - bless_instance_structure is deprecated and will be removed
228 - create has been renamed to _instantiate_module. This method
229 does not construct an object, it evals some code that
230 creates the relevant package in Perl's symbol table.
232 - Class::MOP::Method::Accessor
233 - initialize_body => _initialize_body (this is always called
234 when an object is constructed)
235 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
237 - Class::MOP::Method::Constructor
238 - initialize_body => _initialize_body (this is always called
239 when an object is constructed)
240 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
241 - attributes => _attributes
242 - meta_instance => _meta_instance
244 0.80 Wed, April 1, 2009
246 - Call user_class->meta in fewer places, with the eventual goal
247 of allowing the user to rename or exclude ->meta
248 altogether. Instead uses Class::MOP::class_of. (Sartak)
251 - New class_of function that should be used to retrieve a
252 metaclass. This is unlike get_metaclass_by_name in that it
253 accepts instances, not just class names. (Sartak)
256 - load_first_existing_class didn't actually load the first
257 existing class; instead, it loaded the first existing and
258 compiling class. It now throws an error if a class exists (in
259 @INC) but fails to compile. (hdp)
263 - we had some semi-buggy code that purported to provide a
264 HAS_ISAREV based on whether mro had get_isarev (due to an
265 oversight, it always returned 1). Since mro and MRO::Compat
266 have always had get_isarev, HAS_ISAREV was pointless. This
267 insight simplified the subclasses method by deleting the
268 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
270 0.79 Fri, March 29, 2009
271 * No changes from 0.78_02.
273 0.78_02 Thu, March 26, 2009
275 * Class::MOP::Immutable
276 - A big backwards-incompatible refactoring of the Immutable API,
277 and the make_immutable/make_mutable pieces of the Class
278 API. The core __PACKAGE__->meta->make_immutable API remains
279 the same, however, so this should only affect the most
283 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
284 has been fixed to be backwards compatible with 5.8.x.
287 - Add a hook for rebless_instance_away (Sartak)
288 - Use blessed instead of ref to get an instance's class name
289 in rebless_instance. (Sartak)
291 0.78_01 Wed, March 18, 2009
293 - Revised and reorganized all of the API documentation. All
294 classes now have (more or less) complete API documentation.
297 * Class::MOP::Instance
298 - Reblessing into a package that supports overloading wasn't
299 properly adding overload magic to the object due to a bug
300 in (at least) 5.8.8. We now use $_[1] directly which seems
301 to set the magic properly. (Sartak)
303 * Class::MOP::Attribute
304 - The process_accessors method is now private. A public alias
305 exists (and will stick around for a few releases), but it
306 warns that calling the public method is deprecated.
308 * Class::MOP::Method::Generated
309 - Removed the new and _new methods, since this is an abstract
310 base class, and all existing subclasses implement their own
314 - Stop is_class_loaded from thinking a class is loaded if it
315 only has an empty GV (Florian Ragwitz).
316 - Add a test for this (Yappo).
317 - Refactor get_all_package_symbols to allow short-circuiting
319 - Use this in is_class_loaded (Florian Ragwitz).
320 - Stop segfaulting when trying to get the name from a sub that's
321 still being compiled (Florian Ragwitz).
322 - Add tests for this (Florian Ragwitz).
323 - Prefix all public symbols with "mop_" (Florian Ragwitz).
324 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
325 - Simplify creating simple xs reader methods (Florian Ragwitz).
326 - Make everything compile with c++ compilers (Florian Ragwitz).
327 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
330 - Remove optional test plans for tests depending on Sub::Name as
331 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
334 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
336 0.78 Mon, February 23, 2009
337 * No changes from 0.77_01
339 0.77_01 Sun, February 22, 2009
341 - This package now requires its XS components. Not using
342 Sub::Name lead to different behavior and bugginess in the pure
343 Perl version of the code. A Moose test would fail when run
344 against the pure Perl version of this code.
346 * Class::MOP::Instance
347 - The inline_* methods now quote attribute names themselves, and
348 don't expect to receive a quoted value.
351 0.77 Sat, February 14, 2009
353 - Avoid assertion errors on debugging perls in is_class_loaded
357 - Fixed various corner cases where is_class_loaded incorrectly
358 returned true for a class that wasn't really loaded. (Dave
362 - Add get_all_method_names (Sartak)
363 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
365 * Class::MOP::Package
366 - Disable deprecated get_all_package_symbols in list
367 context. (Florian Ragwitz)
370 - Make sure we generate a BSD-compatible Makefile (Florian
374 - The misspelled "check_metaclass_compatability" method we've
375 kept around for backwards compat_i_bility will be removed in a
376 near future release. You've been warned.
378 0.76 Thu, January 22, 2009
379 * Class::MOP::Method::Generated
380 - Added new private methods to support code generation, which
381 are being used by Moose and can be used by MooseX
383 - Generated methods are now generated with a #line directive
384 reflecting the source of the generated method. (nothingmuch)
387 - Clarified documentation of methods that return
388 Class::MOP::Method objects. (doy)
391 - Clarified documentation of the metaclass cache methods. (Sartak)
394 - Add test showing how the xs Class::MOP::is_class_loaded can
395 be made to operate differently to the pure perl version (t0m)
397 0.75 Wed, December 31, 2008
399 - A class that was made immutable and then mutable could end up
400 sharing an immutable transformer object
401 (Class::MOP::Immutable) with other classes, leading to all
402 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
404 0.74 Tue, December 25, 2008
406 - Add an xs implementation of Class::MOP::is_class_loaded (closes
407 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
408 - Changed internals to make prehashing of hash keys easier and less
409 error-prone. (Florian Ragwitz)
411 - Fix documentation to show that around modifiers happen on both
412 sides of the modified method. (Dave Rolsky)
414 0.73 Tue, December 16, 2008
416 - Don't use Perl_mro_meta_init. It's not part of the public perl
417 api. Fixes failures to build on Win32 (RT #41750). (Florian
419 * t/082_get_code_info.t
420 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
421 munger anonymous subs when under -d and so making the tests
422 succeed in that case.
424 0.72 Mon, December 8, 2008
425 * Class::MOP::Package
426 - Pass options to _new, so subclass' attributes can be
429 - In the docs, indicate that package_name and name are required
430 when calling ->wrap (Stefan O'Rear)
432 0.71_02 Fri, December 5, 2008
433 * Class::MOP::Immutable
434 - Added a new attribute, inlined_constructor, which is true if
435 the constructor was inlined.
436 * Class::MOP::Package
437 - Make get_all_package_symbols return a hash ref in scalar
438 context and deprecate calling it in list context with a
439 warning. (Florian Ragwitz)
441 - Various improvements and refactoring, making things more robust and
442 easier to maintain. (Florian Ragwitz)
444 0.71_01 Wed, December 3, 2008
446 - Add an "execute" method to invoke the body so
447 we can avoid using the coderef overload (Sartak)
448 * Class::MOP::Immutable
449 - When we memoize methods, get their results lazily
450 to remove some compile-time cost (Sartak)
451 - Small speedup from eliminating several method
454 - Some small internal tweaks to try to reduce the number of
455 times we call get_method_map when bootstrapping the MOP. This
456 might make loading Class::MOP (and Moose) a little
457 faster. (Dave Rolsky)
458 - Implemented an optional XS version of get_method_map. Mostly
459 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
460 help form Florian Ragwitz. (Dave Rolsky)
461 - Make the behaviour of of get_all_package_symbols (and
462 therefore get_method_map) consistent for stub methods. Report
463 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
465 0.71 Wed November 26, 2008
468 - Actual package creation has moved upward from
469 Class to Module so that Moose roles can share
472 0.70_01 Mon, November 19, 2008
474 - Fixes for failures with blead (Florian Ragwitz)
475 - Silenced compiler warnings (Florian Ragwitz)
477 0.70 Fri, November 14, 2008
479 - Fixed an odd corner case where the XS version of
480 get_all_package_symbols could cause a segfault. This only
481 happened with inlined constants in Perl 5.10.0 (Florian
484 0.69 Fri, November 7, 2008
485 * Class::MOP::Method::Wrapped
486 - Added introspection methods for method modifiers (Dave Rolsky)
489 0.68 Fri October 24, 2008
491 - Make load_class require by file name instead of module name.
492 This stops confusing error messages when loading '__PACKAGE__'.
494 - Add load_one_class_of function to enable you to load one of a
495 list of classes, rather than having to call load_class multiple
496 times in an eval. (t0m)
498 0.67 Tue October 14, 2008
500 - Call a method on the class after setting the superclass list
501 so that we can get Perl to detect cycles before MRO::Compat
502 spirals into an infinite loop (sartak)
503 - Reported by Schwern, [rt.cpan.org #39001]
504 - In create(), pass unused options on to initialize()
505 - added test for this
507 0.66 Sat September 20, 2008
508 !! This release has an incompatible change regarding !!
509 introspection of a class's method with Class::MOP::Class !!
512 - We (us maintainers) now run all tests with XS and then without
513 XS, which should help us catch skew between the XS/pure Perl
517 ! The alias_method method has been deprecated. It now simply
518 calls add_method instead. There is no distinction between
519 aliased methods and "real" methods.
521 This means that methods added via alias_method now show up as
522 part of the class's method list/map. This is a backwards
523 incompatible change, but seems unlikely to break any
524 code. Famous last words. (Dave Rolsky)
527 - Fixed the spelling of "compatibility", but we still have a
528 "check_metaclass_compatability" method for backwards
531 0.65 Mon September 1, 2008
532 For those not following the series of dev releases, the changes
533 from 0.64 from 0.65 can mostly be summed up as a lot performance
534 improvements by nothingmuch, including new optional XS versions of
535 some methods. Also, Class::MOP now works _without_ any XS modules,
536 for sad systems without a compiler.
539 - Added name and package_name XS accessors, and make sure all
540 the XS and Perl versions work the same way. (Dave Rolsky)
543 - The XS versions of various methods just returned undef when
544 called class methods, rather than dying like the pure Perl
545 versions. (Dave Rolsky)
547 0.64_07 Fri August 29, 2008
549 - Silenced warnings that managed to break Moose tests when XS
550 was loaded. (Dave Rolsky)
551 - Some XS versions of methods were ignored because of typos in
552 MOP.xs. (Dave Rolsky)
554 0.64_06 Mon August 25, 2008
555 * Class::MOP (MOP.xs)
556 - Another MS VC++ fix, cannot declare a variable in the middle
557 of a scope (Taro Nishino).
559 0.64_05 Sun August 24, 2008
561 - None of the dev releases actually loaded the XS properly, but
562 we silently fell back to the pure Perl version of the
565 * Class::MOP (MOP.xs)
566 - Replaced some code that used functions not available on Visual
567 C++ with some Perl XS API bits (Dave Rolsky).
569 0.64_04 Sat August 23, 2008
571 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
573 * pod.t and pod_coveraget.t
574 - These are no longer shipped with the tarball because of bogus
575 failures from CPAN testers. (Dave Rolsky)
577 0.64_03 Thu August 21, 2008
578 * Class::MOP::Package
579 - Some (legit) code was misparsed by earlier 5.8.x
580 releases. (nothingmuch)
583 - Fix a constant in void context warning (nothingmuch)
585 0.64_02 Thu August 21, 2008
586 * Makefile.PL and Class::MOP
587 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
590 - Add missing prereqs that got lost in the switch away from
593 * Class::MOP::Instance
594 - New method - get_all_attributes (nothingmuch)
596 0.64_01 Wed August 20, 2008
598 - We now check to see if you have a compiler. If you don't, the
599 module installs without some XS bits, but will work the same
600 as with XS. This should make it easier to install on platforms
601 without a compiler (like Windows). (Dave Rolsky)
604 - Perl 6 style attribute naming replaced with sane style ('methods', not
605 '%!methods'). These changes should not impact any existing API uses.
609 - Quite a number of optimizations based on profiling, including
610 allowing constructors to take hash references instead of
611 hashes, duplicating some frequently used code in XS, and
612 making constructors immutable. These changes should not impact
613 any existing API uses. (nothingmuch)
616 - Constructors now respect the meta attributes of their subclasses,
617 facilitating MOP extensibility. More related changes will happen in the
618 next several releases. (nothingmuch)
621 - New method - get_all_methods, replaces the deprecated
622 compute_all_applicable_methods. get_all_attributes provided for
623 consistency (nothingmuch)
624 - New method - wrap_method was refactored out of get_method_map
626 - New API for meta instance invalidation - invalidate_meta_instance,
627 invalidate_meta_instances, add_dependent_meta_instance,
628 remove_dependent_meta_instance, called automatically when attribute
629 definitions change and allows notification of dependent subclasses.
632 0.64 Sun August 3, 2008
633 * Class::MOP::Immutable
634 - fixing subtle edge case in immutable when you
636 - clean up option processing (nothingmuch)
638 * Class::MOP::Instance
639 - inlined initialize slot didn't match
640 non-inlined (nothingmuch)
642 0.63 Mon July 7, 2008
644 - load_class will initialize a metaclass even if
645 the class is already loaded (sartak)
646 - load_class now returns the metaclass instance
647 instead of just 1 (sartak)
650 - better error messages (sartak and Dave Rolsky)
652 0.62 Wed June 18, 2008
653 - in is_class_loaded, recognize scalar references (as opposed to globs) in
654 the symbol table as methods (these are optimized constant subs)
656 0.61 Fri. June 13, 2008
657 - Okay, lets give this another try and see if PAUSE
658 recognizes it correct this time.
660 0.60 Thurs. Jun 12, 2008
661 - Fixed a version number issue by bumping all modules
664 0.59 Thurs. Jun 12, 2008
665 !! Several fixes resulting in yet another 25-30% speedup !!
668 - now stores the instance of the instance
669 metaclass to avoid needless recomputation
670 and deletes it when the cache is blown
671 - introduce methods to query Class::MOP::Class for
672 the options used to make it immutable as well as
673 the proper immutable transformer. (groditi)
675 * Class::MOP::Package
676 - {add, has, get, remove}_package_symbol all
677 now accept a HASH ref argument as well as the
678 string. All internal usages now use the HASH
682 - MOP.xs does sanity checks on the coderef
684 - is_class_loaded check now uses code that
685 was improved in Moose's ClassName type
687 - nonsensical (undef, empty, reference) class
688 names now throw a more direct error in
690 - tests for this and other aspects of
696 Class::MOP::Method::Wrapped
697 Class::MOP::Attribute
698 - switched usage of reftype to ref because
701 0.58 Thurs. May 29, 2008
702 (late night release engineering)--
704 - fixing the version is META.yml, no functional
705 changes in this release
707 0.57 Wed. May 28, 2008
708 !! Several speedups resulting in 20-25% speedups !!
709 || (thanks to konobi, groditi, mst & CataMoose) !!
712 - made get_method_map use list_all_package_symbols
713 instead of manually grabbing each symbol
714 - streamlining &initialize somewhat, since it gets
717 * Class::MOP::Package
718 - made {get, has}_package_symbol not call
720 - inlining a few calls to &name with
721 direct HASH access key access
722 - added get_all_package_symbols to fetch
723 a HASH of items based on a type filter
724 similar to list_all_package_symbols
725 - added tests for this
728 Class::MOP::Method::Constructor
729 Class::MOP::Method::Generated
730 Class::MOP::Method::Accessor
731 - added more descriptive error message to help
732 keep people from wasting time tracking an error
733 that is easily fixed by upgrading.
735 * Class::MOP::Immutable
736 - Don't inline a destructor unless the user actually
738 - added tests for this
740 0.56 Saturday, May 24, 2008
742 - we now get the &check_package_cache_flag
743 function from MRO::Compat
744 - All XS based functionality now has a
745 Pure Perl alternative
746 - the CLASS_MOP_NO_XS environment variable
747 can now be used to force non-XS versions
750 * Class::MOP::Attribute
751 - add has_read_method and has_write_method
752 - get_{read,write}_method_ref now wraps the
753 anon-sub ref in the method metaclass when
755 - added tests for this
757 * Class::MOP::Immutable
758 - added the ability to "wrap" methods when
759 making the class immutable
762 - now handling the edge case of ->meta->identifier
763 dying by wrapping add_package_symbol to specifically
764 allow for it to work.
765 - added tests for this
767 * Class::MOP::Attribute
769 Class::MOP::Immutable
770 - any time a method meta object is constructed
771 we make sure to pass the correct package and
772 method name information
775 Class::MOP::Method::Wrapped
776 Class::MOP::Method::Generated
777 Class::MOP::Method::Accessor
778 Class::MOP::Method::Consructor
779 - the &wrap constructor method now requires that a
780 'package_name' and 'name' attribute are passed. This
781 is to help support the no-XS version, and will
782 throw an error if these are not supplied.
783 - all these classes are now bootstrapped properly
784 and now store the package_name and name attributes
787 ~ Build.PL has been removed since the
788 Module::Install support has been removed
790 0.55 Mon. April 28, 2008
791 - All classes now have proper C3 MRO support
792 - added MRO::Compat as a dependency to allow
793 for the C3 MRO support to Just Work in all
797 - rebless_instance now returns the instance
798 it has just blessed, this is mostly to
800 - set the attr correctly in rebless_instance
801 when it has no init_arg
802 - tweaked &linear_isa and &class_precedence_list
803 to support c3 classes.
805 0.54 Fri. March, 14, 2008
808 - making sure that load_class never gets
809 passed a value from @_ or $_ to squash
810 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
813 - make_{immutable,mutable} now return 1
815 - improved error handling in ->create method
816 - rebless_instance now takes extra params which
817 will be used to populate values
818 - added tests for this
821 - localizing the Data::Dumper configurations so
822 that it does not pollute others (RT #33509)
828 Class::MOP::Attribute
829 - these classes no longer define their own ->meta,
830 but instead just inherit from Class::MOP::Object
832 * Class::MOP::Instance
833 Class::MOP::Immutable
834 - these classes now inherit from Class::MOP::Object
837 - fixed the filename length on several
838 test files so we install on VMS better
840 - fixed incorrect use of catdir when it
841 should be catfile (RT #32385)

844 ~~ several doc. fixes and updates ~~
847 Class::MOP::Method::Constructor

849 - making init_arg accept an undefined value
850 to indicate that no constructor args can
851 be passed (thanks to nothingmuch)
852 - added tests for this
853 - added attribute initializer attribute (rjbs)
856 - making this use the new init_arg => undef
857 feature instead of the silly hack from
858 before (thanks to nothingmuch)
860 0.52 Tues. Jan. 22, 2008
862 - fixed bug in rebless_instance
865 * Class::MOP::Method::Constructor
866 - removed assumptions about the existence of
869 0.51 Mon. Jan. 14, 2008
870 ~~~ some misc. doc. fixes ~~~
871 ~~ updated copyright dates ~~
874 - now sets the IS_RUNNING_ON_5_10
875 constant so that we can take advantage
876 of some of the nice bits of 5.10
879 - uses the IS_RUNNING_ON_5_10 flag to
880 optimize the &linearized_isa method
881 and avoid the hack/check for circular
882 inheritence in &class_precedence_list
883 - added rebless_instance method (Sartak)
884 - added tests for this
886 * Class::MOP::Immutable
887 - the immutable class now keeps track of
888 the transformer which immutablized it
890 * Class::MOP::Instance
891 - added rebless_instance_structure method (Sartak)
892 - added tests for this
894 0.50 Fri. Dec. 21, 2007

897 transformation arguments are saved
899 - added tests for this
901 * Class::MOP::Immutable
902 - fixed a bug (see above)
904 * Class::MOP::Attribute
907 0.49 Fri. Dec. 14, 2007
908 !! Class::MOP now loads 2 x faster !!
909 !! with XS speedups (thanks konobi) !!
912 - removed the dependency on B
913 - added two XS functions (thanks konobi)
914 - get_code_info($code) which replaces all
915 the B fiddling we were doing with
916 faster/leaner XS level fiddling
917 - check_package_cache_flag($pkg_name) which
918 returns the PL_sub_generation variable to
919 be used to help manage method caching.
922 In 5.10 or greater this will actually
923 use the mro::get_pkg_gen instead to give
924 even more accurate caching information.
925 blblack++ for that stuff :)
928 - added the &subclasses method (thanks rlb)
929 - added the update_package_cache_flag and
930 reset_package_cache_flag which help keep
931 track of when we need to re-fetch the
933 - Several small improvements to take advantage
934 of the new method map caching features
936 0.48 Mon. Nov. 26, 2007
937 * Class::MOP::Attribute
938 - fixed get_read/write_method to handle the

941 - added more tests for this
943 0.47 Sat. Nov. 24, 2007
944 * Class::MOP::Attribute

951 pruning duplicate classes (this will be even more
952 useful in the 5.10-compat version coming soon)
954 * Class::MOP::Attribute
955 - added the get_read_method_ref and get_write_method_ref
956 methods which allow you to retrieve a CODE ref which
957 can always be used to read or write an attribute.
959 0.45 Thurs. Nov. 13, 2007
960 * Class::MOP::Attribute
961 - Fix error message on confess (groditi)
963 0.44 Thurs. Nov. 13, 2007

987 - removed the relevant attributes
989 * Class::MOP::Method::Constructor
990 - fixed the cached values we had to be more sane
991 - made this a subclass of Class::MOP::Method::Generated
992 - fixed generated constructor so it properly handles
994 - added tests for this
995 - added the option to allow for both inlined and
996 non-inlined constructors.
997 - Update inlined methods for builder and predicate changes (groditi)
999 * Class::MOP::Method::Generated
1000 - added this class as an abstract base for the
1001 Class::MOP::Method::{Constructor,Accessor} classes

1015 - alter symbol table handling to deal with 5.8.x and 5.9.x
1018 - Get rid of the crappy workaround from 0.40/41
1020 0.41 Sun. July 15, 2007
1022 Arghh!!! My TODO test didn't work, so I handle
1023 it manually now so that people can use this
1024 with 5.9.5/bleadperl without issue.
1026 0.40 Tues, July 3, 2007
1028 ~ marked a test in 003_methods.t as TODO
1029 for perl 5.9.5 (this test is irrelvant to
1030 the module functioning on 5.9.5 for the most
1033 0.39 Mon. June 18, 2007
1034 * Class::MOP::Immutable
1035 - added make_metaclass_mutable + docs (groditi)
1036 - removed unused variable
1037 - added create_immutable_transformer
1038 necessary for sane overloading of immutable behavior
1039 - tests for this (groditi)
1042 - Immutability can now be undone,
1043 added make_mutable + tests + docs (groditi)
1044 - Massive changes to the way Immutable is done
1045 for details see comments next to make_immutable
1046 This fixes a bug where custom metaclasses broke
1047 when made immutable. We are now keeping one immutable
1048 metaclass instance per metaclass instead of just one
1049 to prevent isa hierarchy corruption. Memory use will go
1050 up, but I suspect it will be neglible.
1051 - New tests added for this behavior. (groditi)
1053 0.38 Thurs. May 31, 2007
1054 ~~ More documentation updates ~~
1056 * Class::MOP::Package

1063 thanks to groditi for this code, tests
1065 - added tests and POD for this
1068 - fixed RT issue #27329, clone object now
1069 handles undef values correctly.
1070 - added tests for this
1071 - Corrected anon-class handling so that they
1072 will not get reaped when instances still
1073 exist which need to reference them. This is
1074 the correct behavior, hopefully this is an
1075 obscure enough feature that there are not too
1076 many work arounds out in the wild.
1077 - added tests for this by groditi
1078 - updated docs to explain this
1081 - load custom metaclasses automatically (thanks groditi)
1082 - added tests for this behavior
1084 0.37 Sat. March 10, 2007

1093 avoid setting off bool-overloads (found by Carl Franks)
1097 - bad name in a test, causing meaningless failuress.
1102 ~~ GLOBAL CHANGES ~~
1103 - All attribute names are now consistent and follow Perl 6
1104 style (prefixed with the sigil, and ! as the twigil for
1105 private attrs). This should not affect any code, unless
1106 you broke encapsulation, in which case, it is your problem
1109 !! Class::MOP::Class::Immutable has been removed
1111 * Class::MOP::Method::Constructor
1112 - this has been moved out of Class::MOP::Class::Immutable
1113 and is a proper subclass of Class::MOP::Method now.
1116 - this module now uses Class::MOP::Immutable for the
1117 immutable transformation instead of
1118 Class::MOP::Class::Immutable.
1120 + Class::MOP::Immutable
1121 - this module now controls the transformation from a mutable
1122 to an immutable version of the class. Docs for this will
1123 be coming eventually.
1126 0.36 Sun. Nov. 5, 2006
1128 - added a few 'no warnings' lines to keep annoying
1129 (and meaningless) warnings from chirping during
1133 - some more bootstrapping is now done on the new
1136 * Class::MOP::Class::Immutable
1138 - constructor generation is now handled by
1139 the Class::MOP::Method::Constructor class
1141 * Class::MOP::Method::Constructor
1142 - created this to handle constructor generation
1143 in Class::MOP::Class::Immutable
1145 * Class::MOP::Attribute
1147 - attributes now delegate to the
1148 Class::MOP::Method::Accessor to generate
1151 * Class::MOP::Method::Accessor
1152 - all accessor generation functions from
1153 Class::MOP::Attribute have been moved here

1158 - initial prototype of a class browser, more
1159 on this to come. Comments and patches are

1164 re-generated in the bootstrap, instead
1165 they are aliased from the originals

1169 - adjusted tests for this
1170 - added the Class::MOP::Instance attributes

1177 - adjusted tests to compensate
1178 - adjusted docs for this
1181 - changed how methods are dealt with to
1182 encapsulate most of the work into the
1183 &get_method_map method
1184 - made several adjustments for the change
1185 in Class::MOP::Method
1186 - &add_attribute now checks if you are adding
1187 a duplicate name, and properly removes the
1188 old one before installing the new one
1189 - added tests for this
1190 - adjusted docs for this
1192 * Class::MOP::Class::Immutable
1193 - added caching of &get_method_map
1194 - fixed issue with &get_package_symbol
1195 - cleaned up the methods that die (patch by David Wheeler)

1199 &list_all_package_symbols
1201 0.34 Sat. Aug. 26, 2006
1203 - added the %:methods attribute, which like
1204 the $:version and such just actually goes
1205 to the symbol table to get it's stuff.
1206 However, it makes the MOP more complete.
1208 - The &create method now requires that all
1209 but the package name now is passed in as
1210 named parameters. See docs for more info.
1211 - updated docs and tests for this
1213 * Class::MOP::Object
1214 - added &dump method to easily Data::Dumper

1236 are no longer allowed for defaults
1237 - added tests for this
1239 * Class::MOP::Package
1240 - fixed an issue with perl 5.8.1 and how it deals
1241 with symbol tables. The namespace hash is now
1242 always reloaded from the symbol table.
1244 ~ lots of misc. documentation cleanup
1246 0.32 Sat. Aug. 12, 2006
1247 + added Class::MOP::Object so that the
1248 metamodel is more complete (and closer
1249 to what Perl 6 will probably be).

1253 the primary gateway between the metaclass
1254 and the Perl 5 symbol table
1255 - added many tests for this
1256 - this class is now a subclass of
1258 - added some tests to reflect this

1262 use Class::MOP::Package methods instead
1264 * Class::MOP::Module
1265 - adding the $:version attribute in the bootstrap
1266 so that Module has a version as an attribute
1267 - see comment in Class::MOP for details
1268 - added the $:authority attribute to this module
1269 as well as an &identifier method, to bring us
1270 ever closer to Perl 6 goodness
1271 - I have added $AUTHORITY to all the modules
1272 - added tests for this

1288 anywhere within the class hierarchy
1290 * Class::MOP::Attribute
1291 - added &set_value and &get_value for getting
1292 the value of the attribute for a particular
1295 0.30 Wed. July 5, 2006
1296 ---------------------------------------
1297 This is the first version of Class::MOP
1298 to introduce the immutable features which
1299 will be used for optimizating the MOP.
1300 This support should still be considered
1301 experimental, but moving towards stability.
1302 ---------------------------------------
1304 * Created Class::MOP::Class::Immutable
1306 * Created the Class::MOP::Package and
1307 Class::MOP::Module classes to more
1308 closely conform to Perl 6's meta-model
1311 - now inherits from Class::MOP::Module
1312 - several methods moved to ::Module and
1313 ::Package and now inherited
1314 - added tests for this
1316 * Class::MOP::Instance
1317 - added an is_inlinable method to allow other
1318 classes to check before they attempt to optimize.
1319 - added an inline_create_instance to inline
1320 instance creation (of course)
1323 - the Class::MOP::Class::*_package_variable
1324 methods are all now methods of Class::MOP::Package
1325 and called *_package_symbol instead. This is
1326 because they are now more general purpose symbol
1327 table manipulation methods.
1329 0.29_02 Thurs. June 22, 2006
1330 ++ DEVELOPER RELEASE ++
1332 - small change in &create so that it behaves

1389 of the attribute itself, and construct_instance now
1390 delegates appropriately
1392 * Class::MOP::Attribute

1394 of the attribute itself, so we added a method for it
1395 called initialize_instance_slot

1424 0.21 Wed. March 15, 2006
1426 - fixed issue where metaclasses are reaped from

1442 before, after and around modifiers
1443 - added tests and docs for this feature

1452 - &add_after_method_modifier
1453 - &add_around_method_modifier
1454 - added tests and docs for these
1455 - added &find_next_method_by_name which finds the
1456 equivalent of SUPER::method_name
1458 0.12 Thurs. Feb 23, 2006
1459 - reduced the dependency on B, no need to always
1463 - added docs to the C3 method dispatch order test
1464 - fixed missing Algorithm::C3 dependency by making
1465 the test skip if it is not installed
1467 0.11 Mon Feb. 20, 2006
1469 - added example of changing method dispatch order to C3
1472 - changed how clone_instance behaves, it now only does a
1473 shallow clone (see docs for more details)
1474 - added docs and tests
1476 0.10 Tues Feb. 14, 2006
1477 ** This release was mostly about writing more tests and
1478 cleaning out old and dusty code, the MOP should now
1479 be considered "ready to use".
1481 - adding more tests to get coverage up a little higher,
1482 mostly testing errors and edge cases.
1483 - test coverage is now at 99%
1486 - no longer optionally exports to UNIVERSAL::meta or
1487 creates a custom metaclass generator, use the
1488 metaclass pragma instead.
1491 - fixed a number of minor issues which came up in the
1492 error/edge-case tests
1494 * Class::MOP::Attribute
1495 - fixed a number of minor issues which came up in the
1496 error/edge-case tests
1499 - fixing the AttributesWithHistory example, it was broken.
1501 0.06 Thurs Feb. 9, 2006
1503 - adding new metaclass pragma to make setting up the
1504 metaclass a little more straightforward
1507 - clean up bootstrapping to include more complete
1508 attribute definitions for Class::MOP::Class and
1509 Class::MOP::Attribute (accessors, readers, writers,
1510 etc.) ... it is redundant, but is useful meta-info
1514 - fixing minor meta-circularity issue with &meta, it
1515 is now more useful for subclasses
1516 - added &get_attribute_map as an accessor for the
1517 hash of attribute meta objects
1518 - &compute_all_applicable_attributes now just returns
1519 the attribute meta-object, rather than the HASH ref
1520 since all the same info can be gotten from the
1521 attribute meta-object itself
1522 - updated docs & tests to reflect
1523 - added &clone_instance method which does a deep clone
1524 of the instance structure created by &construct_instance
1525 - added docs & tests for this
1526 - added Clone as a dependency
1527 - added &new_object and &clone_object convience methods to
1528 return blessed new or cloned instances
1529 - they handle Class::MOP::Class singletons correctly too
1530 - added docs & tests for this
1531 - cleaned up the &constuct_class_instance so that it behaves
1532 more like &construct_instance (and managed the singletons too)
1533 - added the &check_metaclass_compatibility method to make sure
1534 that metaclasses are upward and downward compatible.
1535 - added tests and docs for this
1538 - adjusting code to use the &Class::MOP::Class::meta
1540 - adjusting code to use the metaclass pragma
1542 0.05 Sat Feb. 4, 2006
1544 - added the &attribute_metaclass and &method_metaclass
1545 attributes which contain a metaclass name to use for
1546 attributes/methods respectively
1549 - bootstrap additional attributes for Class::MOP::Class
1552 - adjusted the example code and tests to use the new
1553 &attribute_metaclass feature of Class::MOP::Class
1554 - added new example:
1557 0.04 Fri Feb. 3, 2006
1559 - some documentation suggestions from #perl6
1561 * Class::MOP::Attribute
1562 - improved error messages
1565 - added new examples:
1566 - AttributesWithHistory
1567 - ClassEncapsultedAttributes
1569 0.03 Fri Feb. 3, 2006
1570 - converted to Module::Build instead of EU::MM
1572 * Class::MOP::Attribute
1573 - refactored method generation code
1574 - attributes are now associated with class directly
1577 - refactored the InsideOut example to take advantage
1578 of the Class::MOP::Attribute refactoring
1579 - changed example files to .pod files and hide thier
1580 package names from PAUSE (I don't want to own these
1581 namespaces really, they are just examples)
1583 0.02 Thurs Feb. 2, 2006
1584 - moving examples from t/lib/* to examples/*
1585 - adding POD documentation to the examples
