1 Revision history for Perl extension Class-MOP.
4 Japan Perl Association has sponsored Goro Fuji to improve startup
5 performance of Class::MOP and Moose. These enhancements may break
6 backwards compatibility if you're doing (or using) complex
7 metaprogramming, so, as always, test your code!

12 - Anonymous classes were not completely destroyed when they went
13 out of scope, leading to a memory leak. RT #47480. (Goro
17 - The get_method, has_method, and add_method methods no longer
18 use get_method_map. Method objects are instantiated
19 lazily. This significantly improves Class::MOP's load
23 - Inline fewer metaclass-level constructors since the ones we
24 have are perfectly fine. This reduces the number of string
27 * Class::MOP::Method::Wrapped
28 - If a method modifier set $_, this caused the modifier to blow
29 up, because of some weird internals. (Jeremy Stashewsky)
33 - Move get_method_map and its various scaffolding into Package. (hdp)
37 * Class::MOP::Class::Immutable::Trait
38 - Made the Trait act like a role with a bunch of "around"
39 modifiers, rather than sticking it in the inheritance
40 hierarchy. This fixes various problems that caused with
41 metaclass compatibility, which broke Fey::ORM.
44 - Allow a blessed code reference as the method body. Fixes a
45 problem interaction with MooseX::Types. (ash)
47 * Class::MOP::Instance
48 - add inline version of rebless_instance_structure. (doy)
49 - change inline_slot_access to use single quotes (gphat)
51 0.88 Tue, Jun 23, 2009
53 - Moved the __INSTANCE__ parameter to _construct_instance from
55 - Fixed some issues involving metaclasses of metaclasses and
58 0.87 Sun, Jun 21, 2009
60 - Made sure to always local-ize $@ and $SIG{__DIE__} before
61 calling an eval. Fixes RT #45973.
64 - Synced docs about immutability with the current reality (which
65 changed back in 0.82_01)
66 - Removed the immutable_transformer method, which had been
67 returning undef since 0.82_01 anyway.
70 - Got rid of tests which needed Moose and improved testing of
71 constructor/destructor inlining warnings. Fixes RT #47119.
73 0.86 Tue, Jun 16, 2009
75 - If you redefined a subroutine at runtime and then wrapped it
76 with a method modifier, the modifier could in some cases wrap
77 the original version of the subroutine. Fixes RT #46957.
80 - make_immutable issues a warning instead of overriding an
81 existing DESTROY method (Dylan William Hardison). Fixes RT
85 * Class::MOP::Attribute
86 - Allow default values to be Class::MOP::Methods. (Florian
88 - Test the above. (Rhesa Rozendaal)
89 - Tweak original commit so the intent matches the accepted
90 behavior (Nicholas Perez)
93 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
96 - Add direct_subclasses method (Sartak)
97 - Tests for subclasses and direct_subclasses (Sartak)
98 - subname is no longer used unconditionally in add_method, but
99 only if the code reference's name is '__ANON__' (nothingmuch)
100 - Add a hook for _superclasses_updated (Sartak)
103 - Remove long, old warning about possibly outdated modules
106 0.84 Tue, May 12, 2009
108 - Depend on Text::Exception 0.27 to avoid failing tests ond old
112 - Made is_class_loaded a little stricter. It was reporting that
113 a class was loaded if it merely had an @ISA variable in its
114 stash. Now it checks that the @ISA var has elements in it.
115 - Deprecate in_global_destruction and subname re-exporting
119 - Explicitly use Devel::GlobalDestruction and Sub::Name
122 * Class::MOP::Package
123 - Disable prototype mismatch warnings for add_package_symbol.
126 - Add test for finding methods from $meta->name->meta before immutable,
129 0.83 Mon, April 27, 2009
131 - Fix segfault when calling get_method_map on a metaclass for an empty
134 0.82_02 Fri, April 24, 2009
135 * Class::MOP::Method::Inlined
136 - Don't inline if the expected method is not defined at all (happens with
137 e.g. Moose::Object::_new is the expected method due to an overridden
140 - Some tests were trying to load Class::MOP::Immutable, which
141 was removed in 0.82_01.
143 0.82_01 Thu, April 23, 2009
144 * Class::MOP::Immutable (and others)
145 - Refactor the immutability system to use a pre-defined class
146 for the immutable metaclass of Class::MOP::Class::Immutable::$class
147 - Rather than generating methods into this class every time, use
148 a Trait (basic mixin) to supply the cached methods
149 - Remove the hack that returns the mutable metaclass for
150 metacircularity in order to provide consistent meta-metaclasses
151 for the Moose compatibility handling code
152 (mst broke it, nothingmuch fixed it)
154 0.82 Mon, April 20, 2009
156 - The deprecation wrappers for some renamed methods were not
157 passing arguments to the new method. (nothingmuch)
159 * Class::MOP::Immutable
160 - Warn during immutablization if the local class provides its own
161 constructor, to parallel the warning in Moose when a superclass
162 provides its own constructor (doy)
164 0.81 Tue, April 7, 2009
167 * Class::MOP::Instance
168 * Class::MOP::Attribute
169 * Class::MOP::Method::Accessor
170 * Class::MOP::Method::Constructor
171 - Include stack traces in the deprecation warnings introduced in
172 0.80_01. (Florian Ragwitz)
175 - Avoid c compiler warnings by declaring some unused function
176 arguments. (Florian Ragwitz)
178 0.80_01 Sun, April 5, 2009
180 - Make sure to preserve any compiler flags already defined in
181 Config.pm. Patch by Vincent Pit. RT #44739.
183 * Many methods have been renamed with a leading underscore, and a
184 few have been deprecated entirely. The methods with a leading
185 underscore are consider "internals only". People writing
186 subclasses or extensions to Class::MOP should feel free to
187 override them, but they are not for "public" use.
190 - construct_class_instance => _construct_class_instance (use new_object)
191 - construct_instance => _construct_instance (use new_object)
192 - check_metaclass_compatibility => _check_metaclass_compatibility
193 - create_meta_instance => _create_meta_instance (use get_meta_instance)
194 - clone_instance => _clone_instance (use clone_object)
195 - compute_all_applicable_methods is deprecated, use get_all_methods
196 - compute_all_applicable_attributes is deprecated, use get_all_attributes
198 - Class::MOP::Instance
199 - bless_instance_structure is deprecated and will be removed
203 - create has been renamed to _instantiate_module. This method
204 does not construct an object, it evals some code that
205 creates the relevant package in Perl's symbol table.
207 - Class::MOP::Method::Accessor
208 - initialize_body => _initialize_body (this is always called
209 when an object is constructed)
210 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
212 - Class::MOP::Method::Constructor
213 - initialize_body => _initialize_body (this is always called
214 when an object is constructed)
215 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
216 - attributes => _attributes
217 - meta_instance => _meta_instance
219 0.80 Wed, April 1, 2009
221 - Call user_class->meta in fewer places, with the eventual goal
222 of allowing the user to rename or exclude ->meta
223 altogether. Instead uses Class::MOP::class_of. (Sartak)
226 - New class_of function that should be used to retrieve a
227 metaclass. This is unlike get_metaclass_by_name in that it
228 accepts instances, not just class names. (Sartak)
231 - load_first_existing_class didn't actually load the first
232 existing class; instead, it loaded the first existing and
233 compiling class. It now throws an error if a class exists (in
234 @INC) but fails to compile. (hdp)
238 - we had some semi-buggy code that purported to provide a
239 HAS_ISAREV based on whether mro had get_isarev (due to an
240 oversight, it always returned 1). Since mro and MRO::Compat
241 have always had get_isarev, HAS_ISAREV was pointless. This
242 insight simplified the subclasses method by deleting the
243 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
245 0.79 Fri, March 29, 2009
246 * No changes from 0.78_02.
248 0.78_02 Thu, March 26, 2009
250 * Class::MOP::Immutable
251 - A big backwards-incompatible refactoring of the Immutable API,
252 and the make_immutable/make_mutable pieces of the Class
253 API. The core __PACKAGE__->meta->make_immutable API remains
254 the same, however, so this should only affect the most
258 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
259 has been fixed to be backwards compatible with 5.8.x.
262 - Add a hook for rebless_instance_away (Sartak)
263 - Use blessed instead of ref to get an instance's class name
264 in rebless_instance. (Sartak)
266 0.78_01 Wed, March 18, 2009
268 - Revised and reorganized all of the API documentation. All
269 classes now have (more or less) complete API documentation.
272 * Class::MOP::Instance
273 - Reblessing into a package that supports overloading wasn't
274 properly adding overload magic to the object due to a bug
275 in (at least) 5.8.8. We now use $_[1] directly which seems
276 to set the magic properly. (Sartak)
278 * Class::MOP::Attribute
279 - The process_accessors method is now private. A public alias
280 exists (and will stick around for a few releases), but it
281 warns that calling the public method is deprecated.
283 * Class::MOP::Method::Generated
284 - Removed the new and _new methods, since this is an abstract
285 base class, and all existing subclasses implement their own
289 - Stop is_class_loaded from thinking a class is loaded if it
290 only has an empty GV (Florian Ragwitz).
291 - Add a test for this (Yappo).
292 - Refactor get_all_package_symbols to allow short-circuiting
294 - Use this in is_class_loaded (Florian Ragwitz).
295 - Stop segfaulting when trying to get the name from a sub that's
296 still being compiled (Florian Ragwitz).
297 - Add tests for this (Florian Ragwitz).
298 - Prefix all public symbols with "mop_" (Florian Ragwitz).
299 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
300 - Simplify creating simple xs reader methods (Florian Ragwitz).
301 - Make everything compile with c++ compilers (Florian Ragwitz).
302 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
305 - Remove optional test plans for tests depending on Sub::Name as
306 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
309 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
311 0.78 Mon, February 23, 2009
312 * No changes from 0.77_01
314 0.77_01 Sun, February 22, 2009
316 - This package now requires its XS components. Not using
317 Sub::Name lead to different behavior and bugginess in the pure
318 Perl version of the code. A Moose test would fail when run
319 against the pure Perl version of this code.
321 * Class::MOP::Instance
322 - The inline_* methods now quote attribute names themselves, and
323 don't expect to receive a quoted value.
326 0.77 Sat, February 14, 2009
328 - Avoid assertion errors on debugging perls in is_class_loaded
332 - Fixed various corner cases where is_class_loaded incorrectly
333 returned true for a class that wasn't really loaded. (Dave
337 - Add get_all_method_names (Sartak)
338 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
340 * Class::MOP::Package
341 - Disable deprecated get_all_package_symbols in list
342 context. (Florian Ragwitz)
345 - Make sure we generate a BSD-compatible Makefile (Florian
349 - The misspelled "check_metaclass_compatability" method we've
350 kept around for backwards compat_i_bility will be removed in a
351 near future release. You've been warned.
353 0.76 Thu, January 22, 2009
354 * Class::MOP::Method::Generated
355 - Added new private methods to support code generation, which
356 are being used by Moose and can be used by MooseX
358 - Generated methods are now generated with a #line directive
359 reflecting the source of the generated method. (nothingmuch)
362 - Clarified documentation of methods that return
363 Class::MOP::Method objects. (doy)
366 - Clarified documentation of the metaclass cache methods. (Sartak)
369 - Add test showing how the xs Class::MOP::is_class_loaded can
370 be made to operate differently to the pure perl version (t0m)
372 0.75 Wed, December 31, 2008
374 - A class that was made immutable and then mutable could end up
375 sharing an immutable transformer object
376 (Class::MOP::Immutable) with other classes, leading to all
377 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
379 0.74 Tue, December 25, 2008
381 - Add an xs implementation of Class::MOP::is_class_loaded (closes
382 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
383 - Changed internals to make prehashing of hash keys easier and less
384 error-prone. (Florian Ragwitz)
386 - Fix documentation to show that around modifiers happen on both
387 sides of the modified method. (Dave Rolsky)
389 0.73 Tue, December 16, 2008
391 - Don't use Perl_mro_meta_init. It's not part of the public perl
392 api. Fixes failures to build on Win32 (RT #41750). (Florian
394 * t/082_get_code_info.t
395 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
396 munger anonymous subs when under -d and so making the tests
397 succeed in that case.
399 0.72 Mon, December 8, 2008
400 * Class::MOP::Package
401 - Pass options to _new, so subclass' attributes can be
404 - In the docs, indicate that package_name and name are required
405 when calling ->wrap (Stefan O'Rear)
407 0.71_02 Fri, December 5, 2008
408 * Class::MOP::Immutable
409 - Added a new attribute, inlined_constructor, which is true if
410 the constructor was inlined.
411 * Class::MOP::Package
412 - Make get_all_package_symbols return a hash ref in scalar
413 context and deprecate calling it in list context with a
414 warning. (Florian Ragwitz)
416 - Various improvements and refactoring, making things more robust and
417 easier to maintain. (Florian Ragwitz)
419 0.71_01 Wed, December 3, 2008
421 - Add an "execute" method to invoke the body so
422 we can avoid using the coderef overload (Sartak)
423 * Class::MOP::Immutable
424 - When we memoize methods, get their results lazily
425 to remove some compile-time cost (Sartak)
426 - Small speedup from eliminating several method
429 - Some small internal tweaks to try to reduce the number of
430 times we call get_method_map when bootstrapping the MOP. This
431 might make loading Class::MOP (and Moose) a little
432 faster. (Dave Rolsky)
433 - Implemented an optional XS version of get_method_map. Mostly
434 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
435 help form Florian Ragwitz. (Dave Rolsky)
436 - Make the behaviour of of get_all_package_symbols (and
437 therefore get_method_map) consistent for stub methods. Report
438 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
440 0.71 Wed November 26, 2008
443 - Actual package creation has moved upward from
444 Class to Module so that Moose roles can share
447 0.70_01 Mon, November 19, 2008
449 - Fixes for failures with blead (Florian Ragwitz)
450 - Silenced compiler warnings (Florian Ragwitz)
452 0.70 Fri, November 14, 2008
454 - Fixed an odd corner case where the XS version of
455 get_all_package_symbols could cause a segfault. This only
456 happened with inlined constants in Perl 5.10.0 (Florian
459 0.69 Fri, November 7, 2008
460 * Class::MOP::Method::Wrapped
461 - Added introspection methods for method modifiers (Dave Rolsky)
464 0.68 Fri October 24, 2008
466 - Make load_class require by file name instead of module name.
467 This stops confusing error messages when loading '__PACKAGE__'.
469 - Add load_one_class_of function to enable you to load one of a
470 list of classes, rather than having to call load_class multiple
471 times in an eval. (t0m)
473 0.67 Tue October 14, 2008
475 - Call a method on the class after setting the superclass list
476 so that we can get Perl to detect cycles before MRO::Compat
477 spirals into an infinite loop (sartak)
478 - Reported by Schwern, [rt.cpan.org #39001]
479 - In create(), pass unused options on to initialize()
480 - added test for this
482 0.66 Sat September 20, 2008
483 !! This release has an incompatible change regarding !!
484 introspection of a class's method with Class::MOP::Class !!
487 - We (us maintainers) now run all tests with XS and then without
488 XS, which should help us catch skew between the XS/pure Perl
492 ! The alias_method method has been deprecated. It now simply
493 calls add_method instead. There is no distinction between
494 aliased methods and "real" methods.
496 This means that methods added via alias_method now show up as
497 part of the class's method list/map. This is a backwards
498 incompatible change, but seems unlikely to break any
499 code. Famous last words. (Dave Rolsky)
502 - Fixed the spelling of "compatibility", but we still have a
503 "check_metaclass_compatability" method for backwards
506 0.65 Mon September 1, 2008
507 For those not following the series of dev releases, the changes
508 from 0.64 from 0.65 can mostly be summed up as a lot performance
509 improvements by nothingmuch, including new optional XS versions of
510 some methods. Also, Class::MOP now works _without_ any XS modules,
511 for sad systems without a compiler.
514 - Added name and package_name XS accessors, and make sure all
515 the XS and Perl versions work the same way. (Dave Rolsky)
518 - The XS versions of various methods just returned undef when
519 called class methods, rather than dying like the pure Perl
520 versions. (Dave Rolsky)
522 0.64_07 Fri August 29, 2008
524 - Silenced warnings that managed to break Moose tests when XS
525 was loaded. (Dave Rolsky)
526 - Some XS versions of methods were ignored because of typos in
527 MOP.xs. (Dave Rolsky)
529 0.64_06 Mon August 25, 2008
530 * Class::MOP (MOP.xs)
531 - Another MS VC++ fix, cannot declare a variable in the middle
532 of a scope (Taro Nishino).
534 0.64_05 Sun August 24, 2008
536 - None of the dev releases actually loaded the XS properly, but
537 we silently fell back to the pure Perl version of the
540 * Class::MOP (MOP.xs)
541 - Replaced some code that used functions not available on Visual
542 C++ with some Perl XS API bits (Dave Rolsky).
544 0.64_04 Sat August 23, 2008
546 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
548 * pod.t and pod_coveraget.t
549 - These are no longer shipped with the tarball because of bogus
550 failures from CPAN testers. (Dave Rolsky)
552 0.64_03 Thu August 21, 2008
553 * Class::MOP::Package
554 - Some (legit) code was misparsed by earlier 5.8.x
555 releases. (nothingmuch)
558 - Fix a constant in void context warning (nothingmuch)
560 0.64_02 Thu August 21, 2008
561 * Makefile.PL and Class::MOP
562 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
565 - Add missing prereqs that got lost in the switch away from
568 * Class::MOP::Instance
569 - New method - get_all_attributes (nothingmuch)
571 0.64_01 Wed August 20, 2008
573 - We now check to see if you have a compiler. If you don't, the
574 module installs without some XS bits, but will work the same
575 as with XS. This should make it easier to install on platforms
576 without a compiler (like Windows). (Dave Rolsky)
579 - Perl 6 style attribute naming replaced with sane style ('methods', not
580 '%!methods'). These changes should not impact any existing API uses.
584 - Quite a number of optimizations based on profiling, including
585 allowing constructors to take hash references instead of
586 hashes, duplicating some frequently used code in XS, and
587 making constructors immutable. These changes should not impact
588 any existing API uses. (nothingmuch)
591 - Constructors now respect the meta attributes of their subclasses,
592 facilitating MOP extensibility. More related changes will happen in the
593 next several releases. (nothingmuch)
596 - New method - get_all_methods, replaces the deprecated
597 compute_all_applicable_methods. get_all_attributes provided for
598 consistency (nothingmuch)
599 - New method - wrap_method was refactored out of get_method_map
601 - New API for meta instance invalidation - invalidate_meta_instance,
602 invalidate_meta_instances, add_dependent_meta_instance,
603 remove_dependent_meta_instance, called automatically when attribute
604 definitions change and allows notification of dependent subclasses.
607 0.64 Sun August 3, 2008
608 * Class::MOP::Immutable
609 - fixing subtle edge case in immutable when you
611 - clean up option processing (nothingmuch)
613 * Class::MOP::Instance
614 - inlined initialize slot didn't match
615 non-inlined (nothingmuch)
617 0.63 Mon July 7, 2008
619 - load_class will initialize a metaclass even if
620 the class is already loaded (sartak)
621 - load_class now returns the metaclass instance
622 instead of just 1 (sartak)
625 - better error messages (sartak and Dave Rolsky)
627 0.62 Wed June 18, 2008
628 - in is_class_loaded, recognize scalar references (as opposed to globs) in
629 the symbol table as methods (these are optimized constant subs)
631 0.61 Fri. June 13, 2008
632 - Okay, lets give this another try and see if PAUSE
633 recognizes it correct this time.
635 0.60 Thurs. Jun 12, 2008
636 - Fixed a version number issue by bumping all modules
639 0.59 Thurs. Jun 12, 2008
640 !! Several fixes resulting in yet another 25-30% speedup !!
643 - now stores the instance of the instance
644 metaclass to avoid needless recomputation
645 and deletes it when the cache is blown
646 - introduce methods to query Class::MOP::Class for
647 the options used to make it immutable as well as
648 the proper immutable transformer. (groditi)
650 * Class::MOP::Package
651 - {add, has, get, remove}_package_symbol all
652 now accept a HASH ref argument as well as the
653 string. All internal usages now use the HASH
657 - MOP.xs does sanity checks on the coderef
659 - is_class_loaded check now uses code that
660 was improved in Moose's ClassName type
662 - nonsensical (undef, empty, reference) class
663 names now throw a more direct error in
665 - tests for this and other aspects of
671 Class::MOP::Method::Wrapped
672 Class::MOP::Attribute
673 - switched usage of reftype to ref because
676 0.58 Thurs. May 29, 2008
677 (late night release engineering)--
679 - fixing the version is META.yml, no functional
680 changes in this release
682 0.57 Wed. May 28, 2008
683 !! Several speedups resulting in 20-25% speedups !!
684 || (thanks to konobi, groditi, mst & CataMoose) !!
687 - made get_method_map use list_all_package_symbols
688 instead of manually grabbing each symbol
689 - streamlining &initialize somewhat, since it gets
692 * Class::MOP::Package
693 - made {get, has}_package_symbol not call
695 - inlining a few calls to &name with
696 direct HASH access key access
697 - added get_all_package_symbols to fetch
698 a HASH of items based on a type filter
699 similar to list_all_package_symbols
700 - added tests for this
703 Class::MOP::Method::Constructor
704 Class::MOP::Method::Generated
705 Class::MOP::Method::Accessor
706 - added more descriptive error message to help
707 keep people from wasting time tracking an error
708 that is easily fixed by upgrading.
710 * Class::MOP::Immutable
711 - Don't inline a destructor unless the user actually
713 - added tests for this
715 0.56 Saturday, May 24, 2008
717 - we now get the &check_package_cache_flag
718 function from MRO::Compat
719 - All XS based functionality now has a
720 Pure Perl alternative
721 - the CLASS_MOP_NO_XS environment variable
722 can now be used to force non-XS versions
725 * Class::MOP::Attribute

732 * Class::MOP::Immutable
733 - added the ability to "wrap" methods when
734 making the class immutable
737 - now handling the edge case of ->meta->identifier
738 dying by wrapping add_package_symbol to specifically
739 allow for it to work.
740 - added tests for this
742 * Class::MOP::Attribute
744 Class::MOP::Immutable
745 - any time a method meta object is constructed
746 we make sure to pass the correct package and
747 method name information
750 Class::MOP::Method::Wrapped
751 Class::MOP::Method::Generated
752 Class::MOP::Method::Accessor
753 Class::MOP::Method::Consructor
754 - the &wrap constructor method now requires that a
755 'package_name' and 'name' attribute are passed. This
756 is to help support the no-XS version, and will
757 throw an error if these are not supplied.
758 - all these classes are now bootstrapped properly
759 and now store the package_name and name attributes
762 ~ Build.PL has been removed since the
763 Module::Install support has been removed
765 0.55 Mon. April 28, 2008
766 - All classes now have proper C3 MRO support
767 - added MRO::Compat as a dependency to allow
768 for the C3 MRO support to Just Work in all
772 - rebless_instance now returns the instance
773 it has just blessed, this is mostly to
775 - set the attr correctly in rebless_instance
776 when it has no init_arg
777 - tweaked &linear_isa and &class_precedence_list
778 to support c3 classes.
780 0.54 Fri. March, 14, 2008
783 - making sure that load_class never gets
784 passed a value from @_ or $_ to squash
785 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
788 - make_{immutable,mutable} now return 1
790 - improved error handling in ->create method
791 - rebless_instance now takes extra params which
792 will be used to populate values
793 - added tests for this
796 - localizing the Data::Dumper configurations so
797 that it does not pollute others (RT #33509)
803 Class::MOP::Attribute
804 - these classes no longer define their own ->meta,
805 but instead just inherit from Class::MOP::Object
807 * Class::MOP::Instance
808 Class::MOP::Immutable
809 - these classes now inherit from Class::MOP::Object
812 - fixed the filename length on several
813 test files so we install on VMS better
815 - fixed incorrect use of catdir when it
816 should be catfile (RT #32385)

819 ~~ several doc. fixes and updates ~~
822 Class::MOP::Method::Constructor

824 - making init_arg accept an undefined value
825 to indicate that no constructor args can
826 be passed (thanks to nothingmuch)
827 - added tests for this
828 - added attribute initializer attribute (rjbs)
831 - making this use the new init_arg => undef
832 feature instead of the silly hack from
833 before (thanks to nothingmuch)
835 0.52 Tues. Jan. 22, 2008
837 - fixed bug in rebless_instance
840 * Class::MOP::Method::Constructor
841 - removed assumptions about the existence of
844 0.51 Mon. Jan. 14, 2008
845 ~~~ some misc. doc. fixes ~~~
846 ~~ updated copyright dates ~~
849 - now sets the IS_RUNNING_ON_5_10
850 constant so that we can take advantage
851 of some of the nice bits of 5.10
854 - uses the IS_RUNNING_ON_5_10 flag to
855 optimize the &linearized_isa method
856 and avoid the hack/check for circular
857 inheritence in &class_precedence_list
858 - added rebless_instance method (Sartak)
859 - added tests for this
861 * Class::MOP::Immutable
862 - the immutable class now keeps track of
863 the transformer which immutablized it

883 !! Class::MOP now loads 2 x faster !!
884 !! with XS speedups (thanks konobi) !!
887 - removed the dependency on B
888 - added two XS functions (thanks konobi)
889 - get_code_info($code) which replaces all
890 the B fiddling we were doing with
891 faster/leaner XS level fiddling
892 - check_package_cache_flag($pkg_name) which
893 returns the PL_sub_generation variable to
894 be used to help manage method caching.
897 In 5.10 or greater this will actually
898 use the mro::get_pkg_gen instead to give
899 even more accurate caching information.
900 blblack++ for that stuff :)
903 - added the &subclasses method (thanks rlb)
904 - added the update_package_cache_flag and
905 reset_package_cache_flag which help keep
906 track of when we need to re-fetch the
908 - Several small improvements to take advantage
909 of the new method map caching features
911 0.48 Mon. Nov. 26, 2007
912 * Class::MOP::Attribute

926 pruning duplicate classes (this will be even more
927 useful in the 5.10-compat version coming soon)
929 * Class::MOP::Attribute
930 - added the get_read_method_ref and get_write_method_ref
931 methods which allow you to retrieve a CODE ref which
932 can always be used to read or write an attribute.
934 0.45 Thurs. Nov. 13, 2007
935 * Class::MOP::Attribute
936 - Fix error message on confess (groditi)
938 0.44 Thurs. Nov. 13, 2007

941 0.43 Thurs. Nov. 13, 2007
943 - Add support for the 'builder' attribute (groditi)
946 - optimise metaclass-already-exists check in

962 - removed the relevant attributes
964 * Class::MOP::Method::Constructor
965 - fixed the cached values we had to be more sane
966 - made this a subclass of Class::MOP::Method::Generated
967 - fixed generated constructor so it properly handles
969 - added tests for this
970 - added the option to allow for both inlined and
971 non-inlined constructors.
972 - Update inlined methods for builder and predicate changes (groditi)
974 * Class::MOP::Method::Generated
975 - added this class as an abstract base for the

993 - Get rid of the crappy workaround from 0.40/41
995 0.41 Sun. July 15, 2007
997 Arghh!!! My TODO test didn't work, so I handle
998 it manually now so that people can use this
999 with 5.9.5/bleadperl without issue.
1001 0.40 Tues, July 3, 2007
1003 ~ marked a test in 003_methods.t as TODO
1004 for perl 5.9.5 (this test is irrelvant to
1005 the module functioning on 5.9.5 for the most
1008 0.39 Mon. June 18, 2007
1009 * Class::MOP::Immutable
1010 - added make_metaclass_mutable + docs (groditi)
1011 - removed unused variable
1012 - added create_immutable_transformer
1013 necessary for sane overloading of immutable behavior
1014 - tests for this (groditi)
1017 - Immutability can now be undone,
1018 added make_mutable + tests + docs (groditi)
1019 - Massive changes to the way Immutable is done
1020 for details see comments next to make_immutable
1021 This fixes a bug where custom metaclasses broke
1022 when made immutable. We are now keeping one immutable
1023 metaclass instance per metaclass instead of just one
1024 to prevent isa hierarchy corruption. Memory use will go
1025 up, but I suspect it will be neglible.
1026 - New tests added for this behavior. (groditi)
1028 0.38 Thurs. May 31, 2007
1029 ~~ More documentation updates ~~
1031 * Class::MOP::Package

1038 thanks to groditi for this code, tests
1040 - added tests and POD for this
1043 - fixed RT issue #27329, clone object now
1044 handles undef values correctly.
1045 - added tests for this
1046 - Corrected anon-class handling so that they
1047 will not get reaped when instances still
1048 exist which need to reference them. This is
1049 the correct behavior, hopefully this is an
1050 obscure enough feature that there are not too
1051 many work arounds out in the wild.
1052 - added tests for this by groditi
1053 - updated docs to explain this
1056 - load custom metaclasses automatically (thanks groditi)
1057 - added tests for this behavior
1059 0.37 Sat. March 10, 2007

1068 avoid setting off bool-overloads (found by Carl Franks)
1072 - bad name in a test, causing meaningless failuress.
1077 ~~ GLOBAL CHANGES ~~
1078 - All attribute names are now consistent and follow Perl 6
1079 style (prefixed with the sigil, and ! as the twigil for
1080 private attrs). This should not affect any code, unless
1081 you broke encapsulation, in which case, it is your problem
1084 !! Class::MOP::Class::Immutable has been removed
1086 * Class::MOP::Method::Constructor
1087 - this has been moved out of Class::MOP::Class::Immutable
1088 and is a proper subclass of Class::MOP::Method now.
1091 - this module now uses Class::MOP::Immutable for the
1092 immutable transformation instead of
1093 Class::MOP::Class::Immutable.
1095 + Class::MOP::Immutable
1096 - this module now controls the transformation from a mutable
1097 to an immutable version of the class. Docs for this will
1098 be coming eventually.
1101 0.36 Sun. Nov. 5, 2006
1103 - added a few 'no warnings' lines to keep annoying
1104 (and meaningless) warnings from chirping during
1108 - some more bootstrapping is now done on the new
1111 * Class::MOP::Class::Immutable
1113 - constructor generation is now handled by
1114 the Class::MOP::Method::Constructor class
1116 * Class::MOP::Method::Constructor
1117 - created this to handle constructor generation
1118 in Class::MOP::Class::Immutable
1120 * Class::MOP::Attribute
1122 - attributes now delegate to the
1123 Class::MOP::Method::Accessor to generate
1126 * Class::MOP::Method::Accessor
1127 - all accessor generation functions from
1128 Class::MOP::Attribute have been moved here

1139 re-generated in the bootstrap, instead
1140 they are aliased from the originals

1144 - adjusted tests for this
1145 - added the Class::MOP::Instance attributes

1152 - adjusted tests to compensate
1153 - adjusted docs for this
1156 - changed how methods are dealt with to
1157 encapsulate most of the work into the
1158 &get_method_map method
1159 - made several adjustments for the change
1160 in Class::MOP::Method
1161 - &add_attribute now checks if you are adding
1162 a duplicate name, and properly removes the
1163 old one before installing the new one
1164 - added tests for this
1165 - adjusted docs for this
1167 * Class::MOP::Class::Immutable
1168 - added caching of &get_method_map

1174 &list_all_package_symbols
1176 0.34 Sat. Aug. 26, 2006
1178 - added the %:methods attribute, which like
1179 the $:version and such just actually goes
1180 to the symbol table to get it's stuff.
1181 However, it makes the MOP more complete.
1183 - The &create method now requires that all
1184 but the package name now is passed in as
1185 named parameters. See docs for more info.
1186 - updated docs and tests for this
1188 * Class::MOP::Object
1189 - added &dump method to easily Data::Dumper

1212 - added tests for this
1214 * Class::MOP::Package
1215 - fixed an issue with perl 5.8.1 and how it deals
1216 with symbol tables. The namespace hash is now
1217 always reloaded from the symbol table.
1219 ~ lots of misc. documentation cleanup
1221 0.32 Sat. Aug. 12, 2006
1222 + added Class::MOP::Object so that the
1223 metamodel is more complete (and closer
1224 to what Perl 6 will probably be).

1228 the primary gateway between the metaclass
1229 and the Perl 5 symbol table
1230 - added many tests for this

1237 use Class::MOP::Package methods instead
1239 * Class::MOP::Module
1240 - adding the $:version attribute in the bootstrap
1241 so that Module has a version as an attribute
1242 - see comment in Class::MOP for details
1243 - added the $:authority attribute to this module
1244 as well as an &identifier method, to bring us
1245 ever closer to Perl 6 goodness
1246 - I have added $AUTHORITY to all the modules
1247 - added tests for this

1266 - added &set_value and &get_value for getting
1267 the value of the attribute for a particular
1270 0.30 Wed. July 5, 2006
1271 ---------------------------------------
1272 This is the first version of Class::MOP
1273 to introduce the immutable features which
1274 will be used for optimizating the MOP.
1275 This support should still be considered
1276 experimental, but moving towards stability.
1277 ---------------------------------------
1279 * Created Class::MOP::Class::Immutable
1281 * Created the Class::MOP::Package and
1282 Class::MOP::Module classes to more
1283 closely conform to Perl 6's meta-model
1286 - now inherits from Class::MOP::Module
1287 - several methods moved to ::Module and
1288 ::Package and now inherited
1289 - added tests for this
1291 * Class::MOP::Instance
1292 - added an is_inlinable method to allow other
1293 classes to check before they attempt to optimize.
1294 - added an inline_create_instance to inline
1295 instance creation (of course)
1298 - the Class::MOP::Class::*_package_variable
1299 methods are all now methods of Class::MOP::Package
1300 and called *_package_symbol instead. This is
1301 because they are now more general purpose symbol
1302 table manipulation methods.
1304 0.29_02 Thurs. June 22, 2006
1305 ++ DEVELOPER RELEASE ++
1307 - small change in &create so that it behaves

1363 - attribute slot initialization is now the responsibility
1364 of the attribute itself, and construct_instance now
1365 delegates appropriately
1367 * Class::MOP::Attribute

1451 0.10 Tues Feb. 14, 2006
1452 ** This release was mostly about writing more tests and
1453 cleaning out old and dusty code, the MOP should now
1454 be considered "ready to use".
1456 - adding more tests to get coverage up a little higher,
1457 mostly testing errors and edge cases.
1458 - test coverage is now at 99%
1461 - no longer optionally exports to UNIVERSAL::meta or
1462 creates a custom metaclass generator, use the
1463 metaclass pragma instead.
1466 - fixed a number of minor issues which came up in the
1467 error/edge-case tests
1469 * Class::MOP::Attribute
1470 - fixed a number of minor issues which came up in the
1471 error/edge-case tests
1474 - fixing the AttributesWithHistory example, it was broken.
1476 0.06 Thurs Feb. 9, 2006
1478 - adding new metaclass pragma to make setting up the
1479 metaclass a little more straightforward
1482 - clean up bootstrapping to include more complete
1483 attribute definitions for Class::MOP::Class and
1484 Class::MOP::Attribute (accessors, readers, writers,
1485 etc.) ... it is redundant, but is useful meta-info
1489 - fixing minor meta-circularity issue with &meta, it
1490 is now more useful for subclasses
1491 - added &get_attribute_map as an accessor for the
1492 hash of attribute meta objects
1493 - &compute_all_applicable_attributes now just returns
1494 the attribute meta-object, rather than the HASH ref
1495 since all the same info can be gotten from the
1496 attribute meta-object itself
1497 - updated docs & tests to reflect
1498 - added &clone_instance method which does a deep clone
1499 of the instance structure created by &construct_instance
1500 - added docs & tests for this
1501 - added Clone as a dependency
1502 - added &new_object and &clone_object convience methods to
1503 return blessed new or cloned instances
1504 - they handle Class::MOP::Class singletons correctly too
1505 - added docs & tests for this
1506 - cleaned up the &constuct_class_instance so that it behaves
1507 more like &construct_instance (and managed the singletons too)
1508 - added the &check_metaclass_compatibility method to make sure
1509 that metaclasses are upward and downward compatible.
1510 - added tests and docs for this
1513 - adjusting code to use the &Class::MOP::Class::meta
1515 - adjusting code to use the metaclass pragma
1517 0.05 Sat Feb. 4, 2006
1519 - added the &attribute_metaclass and &method_metaclass
1520 attributes which contain a metaclass name to use for
1521 attributes/methods respectively
1524 - bootstrap additional attributes for Class::MOP::Class
1527 - adjusted the example code and tests to use the new
1528 &attribute_metaclass feature of Class::MOP::Class
1529 - added new example:
1532 0.04 Fri Feb. 3, 2006
1534 - some documentation suggestions from #perl6
1536 * Class::MOP::Attribute
1537 - improved error messages
1540 - added new examples:
1541 - AttributesWithHistory
1542 - ClassEncapsultedAttributes
1544 0.03 Fri Feb. 3, 2006
1545 - converted to Module::Build instead of EU::MM
1547 * Class::MOP::Attribute
1548 - refactored method generation code
1549 - attributes are now associated with class directly
1552 - refactored the InsideOut example to take advantage
1553 of the Class::MOP::Attribute refactoring
1554 - changed example files to .pod files and hide thier
1555 package names from PAUSE (I don't want to own these
1556 namespaces really, they are just examples)
1558 0.02 Thurs Feb. 2, 2006
1559 - moving examples from t/lib/* to examples/*
1560 - adding POD documentation to the examples
