1 Revision history for Perl extension Class-MOP.
4 Japan Perl Association has sponsored Goro Fuji to improve
5 startup performance of Class::MOP and Moose. These enhancements
6 may break backwards compatibility if you're doing (or using)
7 complex metaprogramming, so, as always, test your code!
8 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
12 - Anonymous classes were not destroyed properly when they went
13 out of scope, leading to a memory leak. RT #47480 (Goro Fuji).
16 - get_method, has_method, and add_method no longer use get_method_map.
17 Methods are more lazily instantiated to improve performance pretty
18 significantly (Goro Fuji)
21 - Inline fewer metaclass-level constructors since the ones we have are
22 perfectly fine. This reduces the number of string evals (Goro Fuji)
26 * Class::MOP::Class::Immutable::Trait
27 - Made the Trait act like a role with a bunch of "around"
28 modifiers, rather than sticking it in the inheritance
29 hierarchy. This fixes various problems that caused with
30 metaclass compatibility, which broke Fey::ORM.
33 - Allow a blessed code reference as the method body. Fixes a
34 problem interaction with MooseX::Types. (ash)
36 * Class::MOP::Instance
37 - add inline version of rebless_instance_structure. (doy)
38 - change inline_slot_access to use single quotes (gphat)
40 0.88 Tue, Jun 23, 2009
42 - Moved the __INSTANCE__ parameter to _construct_instance from
44 - Fixed some issues involving metaclasses of metaclasses and
47 0.87 Sun, Jun 21, 2009
49 - Made sure to always local-ize $@ and $SIG{__DIE__} before
50 calling an eval. Fixes RT #45973.
53 - Synced docs about immutability with the current reality (which
54 changed back in 0.82_01)
55 - Removed the immutable_transformer method, which had been
56 returning undef since 0.82_01 anyway.
59 - Got rid of tests which needed Moose and improved testing of
60 constructor/destructor inlining warnings. Fixes RT #47119.
62 0.86 Tue, Jun 16, 2009
64 - If you redefined a subroutine at runtime and then wrapped it
65 with a method modifier, the modifier could in some cases wrap
66 the original version of the subroutine. Fixes RT #46957.
69 - make_immutable issues a warning instead of overriding an
70 existing DESTROY method (Dylan William Hardison). Fixes RT
74 * Class::MOP::Attribute
75 - Allow default values to be Class::MOP::Methods. (Florian
77 - Test the above. (Rhesa Rozendaal)
78 - Tweak original commit so the intent matches the accepted
79 behavior (Nicholas Perez)
82 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
85 - Add direct_subclasses method (Sartak)
86 - Tests for subclasses and direct_subclasses (Sartak)
87 - subname is no longer used unconditionally in add_method, but
88 only if the code reference's name is '__ANON__' (nothingmuch)
89 - Add a hook for _superclasses_updated (Sartak)
92 - Remove long, old warning about possibly outdated modules
95 0.84 Tue, May 12, 2009
97 - Depend on Text::Exception 0.27 to avoid failing tests ond old
101 - Made is_class_loaded a little stricter. It was reporting that
102 a class was loaded if it merely had an @ISA variable in its
103 stash. Now it checks that the @ISA var has elements in it.
104 - Deprecate in_global_destruction and subname re-exporting
108 - Explicitly use Devel::GlobalDestruction and Sub::Name
111 * Class::MOP::Package
112 - Disable prototype mismatch warnings for add_package_symbol.
115 - Add test for finding methods from $meta->name->meta before immutable,
118 0.83 Mon, April 27, 2009
120 - Fix segfault when calling get_method_map on a metaclass for an empty
123 0.82_02 Fri, April 24, 2009
124 * Class::MOP::Method::Inlined
125 - Don't inline if the expected method is not defined at all (happens with
126 e.g. Moose::Object::_new is the expected method due to an overridden
129 - Some tests were trying to load Class::MOP::Immutable, which
130 was removed in 0.82_01.
132 0.82_01 Thu, April 23, 2009
133 * Class::MOP::Immutable (and others)
134 - Refactor the immutability system to use a pre-defined class
135 for the immutable metaclass of Class::MOP::Class::Immutable::$class
136 - Rather than generating methods into this class every time, use
137 a Trait (basic mixin) to supply the cached methods
138 - Remove the hack that returns the mutable metaclass for
139 metacircularity in order to provide consistent meta-metaclasses
140 for the Moose compatibility handling code
141 (mst broke it, nothingmuch fixed it)
143 0.82 Mon, April 20, 2009
145 - The deprecation wrappers for some renamed methods were not
146 passing arguments to the new method. (nothingmuch)
148 * Class::MOP::Immutable
149 - Warn during immutablization if the local class provides its own
150 constructor, to parallel the warning in Moose when a superclass
151 provides its own constructor (doy)
153 0.81 Tue, April 7, 2009
156 * Class::MOP::Instance
157 * Class::MOP::Attribute
158 * Class::MOP::Method::Accessor
159 * Class::MOP::Method::Constructor
160 - Include stack traces in the deprecation warnings introduced in
161 0.80_01. (Florian Ragwitz)
164 - Avoid c compiler warnings by declaring some unused function
165 arguments. (Florian Ragwitz)
167 0.80_01 Sun, April 5, 2009
169 - Make sure to preserve any compiler flags already defined in
170 Config.pm. Patch by Vincent Pit. RT #44739.
172 * Many methods have been renamed with a leading underscore, and a
173 few have been deprecated entirely. The methods with a leading
174 underscore are consider "internals only". People writing
175 subclasses or extensions to Class::MOP should feel free to
176 override them, but they are not for "public" use.
179 - construct_class_instance => _construct_class_instance (use new_object)
180 - construct_instance => _construct_instance (use new_object)
181 - check_metaclass_compatibility => _check_metaclass_compatibility
182 - create_meta_instance => _create_meta_instance (use get_meta_instance)
183 - clone_instance => _clone_instance (use clone_object)
184 - compute_all_applicable_methods is deprecated, use get_all_methods
185 - compute_all_applicable_attributes is deprecated, use get_all_attributes
187 - Class::MOP::Instance
188 - bless_instance_structure is deprecated and will be removed
192 - create has been renamed to _instantiate_module. This method
193 does not construct an object, it evals some code that
194 creates the relevant package in Perl's symbol table.
196 - Class::MOP::Method::Accessor
197 - initialize_body => _initialize_body (this is always called
198 when an object is constructed)
199 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
201 - Class::MOP::Method::Constructor
202 - initialize_body => _initialize_body (this is always called
203 when an object is constructed)
204 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
205 - attributes => _attributes
206 - meta_instance => _meta_instance
208 0.80 Wed, April 1, 2009
210 - Call user_class->meta in fewer places, with the eventual goal
211 of allowing the user to rename or exclude ->meta
212 altogether. Instead uses Class::MOP::class_of. (Sartak)
215 - New class_of function that should be used to retrieve a
216 metaclass. This is unlike get_metaclass_by_name in that it
217 accepts instances, not just class names. (Sartak)
220 - load_first_existing_class didn't actually load the first
221 existing class; instead, it loaded the first existing and
222 compiling class. It now throws an error if a class exists (in
223 @INC) but fails to compile. (hdp)
227 - we had some semi-buggy code that purported to provide a
228 HAS_ISAREV based on whether mro had get_isarev (due to an
229 oversight, it always returned 1). Since mro and MRO::Compat
230 have always had get_isarev, HAS_ISAREV was pointless. This
231 insight simplified the subclasses method by deleting the
232 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
234 0.79 Fri, March 29, 2009
235 * No changes from 0.78_02.
237 0.78_02 Thu, March 26, 2009
239 * Class::MOP::Immutable
240 - A big backwards-incompatible refactoring of the Immutable API,
241 and the make_immutable/make_mutable pieces of the Class
242 API. The core __PACKAGE__->meta->make_immutable API remains
243 the same, however, so this should only affect the most
247 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
248 has been fixed to be backwards compatible with 5.8.x.
251 - Add a hook for rebless_instance_away (Sartak)
252 - Use blessed instead of ref to get an instance's class name
253 in rebless_instance. (Sartak)
255 0.78_01 Wed, March 18, 2009
257 - Revised and reorganized all of the API documentation. All
258 classes now have (more or less) complete API documentation.
261 * Class::MOP::Instance
262 - Reblessing into a package that supports overloading wasn't
263 properly adding overload magic to the object due to a bug
264 in (at least) 5.8.8. We now use $_[1] directly which seems
265 to set the magic properly. (Sartak)
267 * Class::MOP::Attribute
268 - The process_accessors method is now private. A public alias
269 exists (and will stick around for a few releases), but it
270 warns that calling the public method is deprecated.
272 * Class::MOP::Method::Generated
273 - Removed the new and _new methods, since this is an abstract
274 base class, and all existing subclasses implement their own
278 - Stop is_class_loaded from thinking a class is loaded if it
279 only has an empty GV (Florian Ragwitz).
280 - Add a test for this (Yappo).
281 - Refactor get_all_package_symbols to allow short-circuiting
283 - Use this in is_class_loaded (Florian Ragwitz).
284 - Stop segfaulting when trying to get the name from a sub that's
285 still being compiled (Florian Ragwitz).
286 - Add tests for this (Florian Ragwitz).
287 - Prefix all public symbols with "mop_" (Florian Ragwitz).
288 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
289 - Simplify creating simple xs reader methods (Florian Ragwitz).
290 - Make everything compile with c++ compilers (Florian Ragwitz).
291 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
294 - Remove optional test plans for tests depending on Sub::Name as
295 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
298 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
300 0.78 Mon, February 23, 2009
301 * No changes from 0.77_01
303 0.77_01 Sun, February 22, 2009
305 - This package now requires its XS components. Not using
306 Sub::Name lead to different behavior and bugginess in the pure
307 Perl version of the code. A Moose test would fail when run
308 against the pure Perl version of this code.
310 * Class::MOP::Instance
311 - The inline_* methods now quote attribute names themselves, and
312 don't expect to receive a quoted value.
315 0.77 Sat, February 14, 2009
317 - Avoid assertion errors on debugging perls in is_class_loaded
321 - Fixed various corner cases where is_class_loaded incorrectly
322 returned true for a class that wasn't really loaded. (Dave
326 - Add get_all_method_names (Sartak)
327 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
329 * Class::MOP::Package
330 - Disable deprecated get_all_package_symbols in list
331 context. (Florian Ragwitz)
334 - Make sure we generate a BSD-compatible Makefile (Florian
338 - The misspelled "check_metaclass_compatability" method we've
339 kept around for backwards compat_i_bility will be removed in a
340 near future release. You've been warned.
342 0.76 Thu, January 22, 2009
343 * Class::MOP::Method::Generated
344 - Added new private methods to support code generation, which
345 are being used by Moose and can be used by MooseX
347 - Generated methods are now generated with a #line directive
348 reflecting the source of the generated method. (nothingmuch)
351 - Clarified documentation of methods that return
352 Class::MOP::Method objects. (doy)
355 - Clarified documentation of the metaclass cache methods. (Sartak)
358 - Add test showing how the xs Class::MOP::is_class_loaded can
359 be made to operate differently to the pure perl version (t0m)
361 0.75 Wed, December 31, 2008
363 - A class that was made immutable and then mutable could end up
364 sharing an immutable transformer object
365 (Class::MOP::Immutable) with other classes, leading to all
366 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
368 0.74 Tue, December 25, 2008
370 - Add an xs implementation of Class::MOP::is_class_loaded (closes
371 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
372 - Changed internals to make prehashing of hash keys easier and less
373 error-prone. (Florian Ragwitz)
375 - Fix documentation to show that around modifiers happen on both
376 sides of the modified method. (Dave Rolsky)
378 0.73 Tue, December 16, 2008
380 - Don't use Perl_mro_meta_init. It's not part of the public perl
381 api. Fixes failures to build on Win32 (RT #41750). (Florian
383 * t/082_get_code_info.t
384 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
385 munger anonymous subs when under -d and so making the tests
386 succeed in that case.
388 0.72 Mon, December 8, 2008
389 * Class::MOP::Package
390 - Pass options to _new, so subclass' attributes can be
393 - In the docs, indicate that package_name and name are required
394 when calling ->wrap (Stefan O'Rear)
396 0.71_02 Fri, December 5, 2008
397 * Class::MOP::Immutable
398 - Added a new attribute, inlined_constructor, which is true if
399 the constructor was inlined.
400 * Class::MOP::Package
401 - Make get_all_package_symbols return a hash ref in scalar
402 context and deprecate calling it in list context with a
403 warning. (Florian Ragwitz)
405 - Various improvements and refactoring, making things more robust and
406 easier to maintain. (Florian Ragwitz)
408 0.71_01 Wed, December 3, 2008
410 - Add an "execute" method to invoke the body so
411 we can avoid using the coderef overload (Sartak)
412 * Class::MOP::Immutable
413 - When we memoize methods, get their results lazily
414 to remove some compile-time cost (Sartak)
415 - Small speedup from eliminating several method
418 - Some small internal tweaks to try to reduce the number of
419 times we call get_method_map when bootstrapping the MOP. This
420 might make loading Class::MOP (and Moose) a little
421 faster. (Dave Rolsky)
422 - Implemented an optional XS version of get_method_map. Mostly
423 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
424 help form Florian Ragwitz. (Dave Rolsky)
425 - Make the behaviour of of get_all_package_symbols (and
426 therefore get_method_map) consistent for stub methods. Report
427 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
429 0.71 Wed November 26, 2008
432 - Actual package creation has moved upward from
433 Class to Module so that Moose roles can share
436 0.70_01 Mon, November 19, 2008
438 - Fixes for failures with blead (Florian Ragwitz)
439 - Silenced compiler warnings (Florian Ragwitz)
441 0.70 Fri, November 14, 2008
443 - Fixed an odd corner case where the XS version of
444 get_all_package_symbols could cause a segfault. This only
445 happened with inlined constants in Perl 5.10.0 (Florian
448 0.69 Fri, November 7, 2008
449 * Class::MOP::Method::Wrapped
450 - Added introspection methods for method modifiers (Dave Rolsky)
453 0.68 Fri October 24, 2008
455 - Make load_class require by file name instead of module name.
456 This stops confusing error messages when loading '__PACKAGE__'.
458 - Add load_one_class_of function to enable you to load one of a
459 list of classes, rather than having to call load_class multiple
460 times in an eval. (t0m)
462 0.67 Tue October 14, 2008
464 - Call a method on the class after setting the superclass list
465 so that we can get Perl to detect cycles before MRO::Compat
466 spirals into an infinite loop (sartak)
467 - Reported by Schwern, [rt.cpan.org #39001]
468 - In create(), pass unused options on to initialize()
469 - added test for this
471 0.66 Sat September 20, 2008
472 !! This release has an incompatible change regarding !!
473 introspection of a class's method with Class::MOP::Class !!
476 - We (us maintainers) now run all tests with XS and then without
477 XS, which should help us catch skew between the XS/pure Perl
481 ! The alias_method method has been deprecated. It now simply
482 calls add_method instead. There is no distinction between
483 aliased methods and "real" methods.
485 This means that methods added via alias_method now show up as
486 part of the class's method list/map. This is a backwards
487 incompatible change, but seems unlikely to break any
488 code. Famous last words. (Dave Rolsky)
491 - Fixed the spelling of "compatibility", but we still have a
492 "check_metaclass_compatability" method for backwards
495 0.65 Mon September 1, 2008
496 For those not following the series of dev releases, the changes
497 from 0.64 from 0.65 can mostly be summed up as a lot performance
498 improvements by nothingmuch, including new optional XS versions of
499 some methods. Also, Class::MOP now works _without_ any XS modules,
500 for sad systems without a compiler.
503 - Added name and package_name XS accessors, and make sure all
504 the XS and Perl versions work the same way. (Dave Rolsky)
507 - The XS versions of various methods just returned undef when
508 called class methods, rather than dying like the pure Perl
509 versions. (Dave Rolsky)
511 0.64_07 Fri August 29, 2008
513 - Silenced warnings that managed to break Moose tests when XS
514 was loaded. (Dave Rolsky)
515 - Some XS versions of methods were ignored because of typos in
516 MOP.xs. (Dave Rolsky)
518 0.64_06 Mon August 25, 2008
519 * Class::MOP (MOP.xs)
520 - Another MS VC++ fix, cannot declare a variable in the middle
521 of a scope (Taro Nishino).
523 0.64_05 Sun August 24, 2008
525 - None of the dev releases actually loaded the XS properly, but
526 we silently fell back to the pure Perl version of the
529 * Class::MOP (MOP.xs)
530 - Replaced some code that used functions not available on Visual
531 C++ with some Perl XS API bits (Dave Rolsky).
533 0.64_04 Sat August 23, 2008
535 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
537 * pod.t and pod_coveraget.t
538 - These are no longer shipped with the tarball because of bogus
539 failures from CPAN testers. (Dave Rolsky)
541 0.64_03 Thu August 21, 2008
542 * Class::MOP::Package
543 - Some (legit) code was misparsed by earlier 5.8.x
544 releases. (nothingmuch)
547 - Fix a constant in void context warning (nothingmuch)
549 0.64_02 Thu August 21, 2008
550 * Makefile.PL and Class::MOP
551 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
554 - Add missing prereqs that got lost in the switch away from
557 * Class::MOP::Instance
558 - New method - get_all_attributes (nothingmuch)
560 0.64_01 Wed August 20, 2008
562 - We now check to see if you have a compiler. If you don't, the
563 module installs without some XS bits, but will work the same
564 as with XS. This should make it easier to install on platforms
565 without a compiler (like Windows). (Dave Rolsky)
568 - Perl 6 style attribute naming replaced with sane style ('methods', not
569 '%!methods'). These changes should not impact any existing API uses.
573 - Quite a number of optimizations based on profiling, including
574 allowing constructors to take hash references instead of
575 hashes, duplicating some frequently used code in XS, and
576 making constructors immutable. These changes should not impact
577 any existing API uses. (nothingmuch)
580 - Constructors now respect the meta attributes of their subclasses,
581 facilitating MOP extensibility. More related changes will happen in the
582 next several releases. (nothingmuch)
585 - New method - get_all_methods, replaces the deprecated
586 compute_all_applicable_methods. get_all_attributes provided for
587 consistency (nothingmuch)
588 - New method - wrap_method was refactored out of get_method_map
590 - New API for meta instance invalidation - invalidate_meta_instance,
591 invalidate_meta_instances, add_dependent_meta_instance,
592 remove_dependent_meta_instance, called automatically when attribute
593 definitions change and allows notification of dependent subclasses.
596 0.64 Sun August 3, 2008
597 * Class::MOP::Immutable
598 - fixing subtle edge case in immutable when you
600 - clean up option processing (nothingmuch)
602 * Class::MOP::Instance
603 - inlined initialize slot didn't match
604 non-inlined (nothingmuch)
606 0.63 Mon July 7, 2008
608 - load_class will initialize a metaclass even if
609 the class is already loaded (sartak)
610 - load_class now returns the metaclass instance
611 instead of just 1 (sartak)
614 - better error messages (sartak and Dave Rolsky)
616 0.62 Wed June 18, 2008
617 - in is_class_loaded, recognize scalar references (as opposed to globs) in
618 the symbol table as methods (these are optimized constant subs)
620 0.61 Fri. June 13, 2008
621 - Okay, lets give this another try and see if PAUSE
622 recognizes it correct this time.
624 0.60 Thurs. Jun 12, 2008
625 - Fixed a version number issue by bumping all modules
628 0.59 Thurs. Jun 12, 2008
629 !! Several fixes resulting in yet another 25-30% speedup !!
632 - now stores the instance of the instance
633 metaclass to avoid needless recomputation
634 and deletes it when the cache is blown
635 - introduce methods to query Class::MOP::Class for
636 the options used to make it immutable as well as
637 the proper immutable transformer. (groditi)
639 * Class::MOP::Package
640 - {add, has, get, remove}_package_symbol all
641 now accept a HASH ref argument as well as the
642 string. All internal usages now use the HASH
646 - MOP.xs does sanity checks on the coderef
648 - is_class_loaded check now uses code that
649 was improved in Moose's ClassName type
651 - nonsensical (undef, empty, reference) class
652 names now throw a more direct error in
654 - tests for this and other aspects of
660 Class::MOP::Method::Wrapped
661 Class::MOP::Attribute
662 - switched usage of reftype to ref because
665 0.58 Thurs. May 29, 2008
666 (late night release engineering)--
668 - fixing the version is META.yml, no functional
669 changes in this release
671 0.57 Wed. May 28, 2008
672 !! Several speedups resulting in 20-25% speedups !!
673 || (thanks to konobi, groditi, mst & CataMoose) !!
676 - made get_method_map use list_all_package_symbols
677 instead of manually grabbing each symbol
678 - streamlining &initialize somewhat, since it gets
681 * Class::MOP::Package
682 - made {get, has}_package_symbol not call
684 - inlining a few calls to &name with
685 direct HASH access key access
686 - added get_all_package_symbols to fetch
687 a HASH of items based on a type filter
688 similar to list_all_package_symbols
689 - added tests for this
692 Class::MOP::Method::Constructor
693 Class::MOP::Method::Generated
694 Class::MOP::Method::Accessor
695 - added more descriptive error message to help
696 keep people from wasting time tracking an error
697 that is easily fixed by upgrading.
699 * Class::MOP::Immutable
700 - Don't inline a destructor unless the user actually
702 - added tests for this
704 0.56 Saturday, May 24, 2008
706 - we now get the &check_package_cache_flag
707 function from MRO::Compat
708 - All XS based functionality now has a
709 Pure Perl alternative
710 - the CLASS_MOP_NO_XS environment variable
711 can now be used to force non-XS versions
714 * Class::MOP::Attribute

717 anon-sub ref in the method metaclass when
719 - added tests for this
721 * Class::MOP::Immutable
722 - added the ability to "wrap" methods when
723 making the class immutable
726 - now handling the edge case of ->meta->identifier
727 dying by wrapping add_package_symbol to specifically
728 allow for it to work.
729 - added tests for this
731 * Class::MOP::Attribute
733 Class::MOP::Immutable
734 - any time a method meta object is constructed
735 we make sure to pass the correct package and
736 method name information
739 Class::MOP::Method::Wrapped
740 Class::MOP::Method::Generated
741 Class::MOP::Method::Accessor
742 Class::MOP::Method::Consructor
743 - the &wrap constructor method now requires that a
744 'package_name' and 'name' attribute are passed. This
745 is to help support the no-XS version, and will
746 throw an error if these are not supplied.
747 - all these classes are now bootstrapped properly
748 and now store the package_name and name attributes
751 ~ Build.PL has been removed since the
752 Module::Install support has been removed
754 0.55 Mon. April 28, 2008
755 - All classes now have proper C3 MRO support
756 - added MRO::Compat as a dependency to allow
757 for the C3 MRO support to Just Work in all
761 - rebless_instance now returns the instance
762 it has just blessed, this is mostly to
764 - set the attr correctly in rebless_instance
765 when it has no init_arg
766 - tweaked &linear_isa and &class_precedence_list
767 to support c3 classes.
769 0.54 Fri. March, 14, 2008
772 - making sure that load_class never gets
773 passed a value from @_ or $_ to squash
774 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
777 - make_{immutable,mutable} now return 1
779 - improved error handling in ->create method
780 - rebless_instance now takes extra params which
781 will be used to populate values
782 - added tests for this
785 - localizing the Data::Dumper configurations so
786 that it does not pollute others (RT #33509)
792 Class::MOP::Attribute
793 - these classes no longer define their own ->meta,
794 but instead just inherit from Class::MOP::Object
796 * Class::MOP::Instance
797 Class::MOP::Immutable
798 - these classes now inherit from Class::MOP::Object
801 - fixed the filename length on several
802 test files so we install on VMS better
804 - fixed incorrect use of catdir when it
805 should be catfile (RT #32385)

808 ~~ several doc. fixes and updates ~~
811 Class::MOP::Method::Constructor
812 Class::MOP::Attribute
813 - making init_arg accept an undefined value
814 to indicate that no constructor args can
815 be passed (thanks to nothingmuch)
816 - added tests for this
817 - added attribute initializer attribute (rjbs)
820 - making this use the new init_arg => undef
821 feature instead of the silly hack from
822 before (thanks to nothingmuch)
824 0.52 Tues. Jan. 22, 2008
826 - fixed bug in rebless_instance
829 * Class::MOP::Method::Constructor
830 - removed assumptions about the existence of
833 0.51 Mon. Jan. 14, 2008
834 ~~~ some misc. doc. fixes ~~~
835 ~~ updated copyright dates ~~
838 - now sets the IS_RUNNING_ON_5_10
839 constant so that we can take advantage
840 of some of the nice bits of 5.10
843 - uses the IS_RUNNING_ON_5_10 flag to
844 optimize the &linearized_isa method
845 and avoid the hack/check for circular
846 inheritence in &class_precedence_list
847 - added rebless_instance method (Sartak)
848 - added tests for this
850 * Class::MOP::Immutable
851 - the immutable class now keeps track of

872 !! Class::MOP now loads 2 x faster !!
873 !! with XS speedups (thanks konobi) !!
876 - removed the dependency on B
877 - added two XS functions (thanks konobi)
878 - get_code_info($code) which replaces all
879 the B fiddling we were doing with
880 faster/leaner XS level fiddling
881 - check_package_cache_flag($pkg_name) which
882 returns the PL_sub_generation variable to
883 be used to help manage method caching.
886 In 5.10 or greater this will actually
887 use the mro::get_pkg_gen instead to give
888 even more accurate caching information.
889 blblack++ for that stuff :)
892 - added the &subclasses method (thanks rlb)
893 - added the update_package_cache_flag and
894 reset_package_cache_flag which help keep
895 track of when we need to re-fetch the
897 - Several small improvements to take advantage
898 of the new method map caching features
900 0.48 Mon. Nov. 26, 2007
901 * Class::MOP::Attribute
902 - fixed get_read/write_method to handle the

915 pruning duplicate classes (this will be even more
916 useful in the 5.10-compat version coming soon)
918 * Class::MOP::Attribute
919 - added the get_read_method_ref and get_write_method_ref
920 methods which allow you to retrieve a CODE ref which
921 can always be used to read or write an attribute.
923 0.45 Thurs. Nov. 13, 2007
924 * Class::MOP::Attribute
925 - Fix error message on confess (groditi)
927 0.44 Thurs. Nov. 13, 2007

932 - Add support for the 'builder' attribute (groditi)
935 - optimise metaclass-already-exists check in
936 construct_class_instance (groditi)

955 - made this a subclass of Class::MOP::Method::Generated
956 - fixed generated constructor so it properly handles
958 - added tests for this
959 - added the option to allow for both inlined and
960 non-inlined constructors.
961 - Update inlined methods for builder and predicate changes (groditi)
963 * Class::MOP::Method::Generated
964 - added this class as an abstract base for the

982 - Get rid of the crappy workaround from 0.40/41
984 0.41 Sun. July 15, 2007
986 Arghh!!! My TODO test didn't work, so I handle
987 it manually now so that people can use this
988 with 5.9.5/bleadperl without issue.
990 0.40 Tues, July 3, 2007
992 ~ marked a test in 003_methods.t as TODO
993 for perl 5.9.5 (this test is irrelvant to
994 the module functioning on 5.9.5 for the most
997 0.39 Mon. June 18, 2007
998 * Class::MOP::Immutable
999 - added make_metaclass_mutable + docs (groditi)
1000 - removed unused variable
1001 - added create_immutable_transformer
1002 necessary for sane overloading of immutable behavior
1003 - tests for this (groditi)
1006 - Immutability can now be undone,
1007 added make_mutable + tests + docs (groditi)
1008 - Massive changes to the way Immutable is done
1009 for details see comments next to make_immutable
1010 This fixes a bug where custom metaclasses broke
1011 when made immutable. We are now keeping one immutable
1012 metaclass instance per metaclass instead of just one
1013 to prevent isa hierarchy corruption. Memory use will go
1014 up, but I suspect it will be neglible.
1015 - New tests added for this behavior. (groditi)
1017 0.38 Thurs. May 31, 2007
1018 ~~ More documentation updates ~~
1020 * Class::MOP::Package

1026 - added get_read_method and get_write_method
1027 thanks to groditi for this code, tests
1029 - added tests and POD for this
1032 - fixed RT issue #27329, clone object now
1033 handles undef values correctly.
1034 - added tests for this
1035 - Corrected anon-class handling so that they
1036 will not get reaped when instances still
1037 exist which need to reference them. This is
1038 the correct behavior, hopefully this is an
1039 obscure enough feature that there are not too
1040 many work arounds out in the wild.
1041 - added tests for this by groditi
1042 - updated docs to explain this
1045 - load custom metaclasses automatically (thanks groditi)
1046 - added tests for this behavior
1048 0.37 Sat. March 10, 2007

1057 avoid setting off bool-overloads (found by Carl Franks)
1061 - bad name in a test, causing meaningless failuress.
1066 ~~ GLOBAL CHANGES ~~
1067 - All attribute names are now consistent and follow Perl 6
1068 style (prefixed with the sigil, and ! as the twigil for
1069 private attrs). This should not affect any code, unless
1070 you broke encapsulation, in which case, it is your problem
1073 !! Class::MOP::Class::Immutable has been removed
1075 * Class::MOP::Method::Constructor
1076 - this has been moved out of Class::MOP::Class::Immutable
1077 and is a proper subclass of Class::MOP::Method now.
1080 - this module now uses Class::MOP::Immutable for the
1081 immutable transformation instead of
1082 Class::MOP::Class::Immutable.
1084 + Class::MOP::Immutable
1085 - this module now controls the transformation from a mutable
1086 to an immutable version of the class. Docs for this will
1087 be coming eventually.
1090 0.36 Sun. Nov. 5, 2006
1092 - added a few 'no warnings' lines to keep annoying
1093 (and meaningless) warnings from chirping during
1097 - some more bootstrapping is now done on the new
1100 * Class::MOP::Class::Immutable
1102 - constructor generation is now handled by
1103 the Class::MOP::Method::Constructor class
1105 * Class::MOP::Method::Constructor
1106 - created this to handle constructor generation
1107 in Class::MOP::Class::Immutable
1109 * Class::MOP::Attribute
1111 - attributes now delegate to the
1112 Class::MOP::Method::Accessor to generate
1115 * Class::MOP::Method::Accessor
1116 - all accessor generation functions from
1117 Class::MOP::Attribute have been moved here

1133 - adjusted tests for this
1134 - added the Class::MOP::Instance attributes

1141 - adjusted tests to compensate
1142 - adjusted docs for this
1145 - changed how methods are dealt with to
1146 encapsulate most of the work into the
1147 &get_method_map method
1148 - made several adjustments for the change
1149 in Class::MOP::Method
1150 - &add_attribute now checks if you are adding
1151 a duplicate name, and properly removes the
1152 old one before installing the new one

1154 - adjusted docs for this
1156 * Class::MOP::Class::Immutable
1157 - added caching of &get_method_map

1163 &list_all_package_symbols
1165 0.34 Sat. Aug. 26, 2006
1167 - added the %:methods attribute, which like
1168 the $:version and such just actually goes
1169 to the symbol table to get it's stuff.
1170 However, it makes the MOP more complete.
1172 - The &create method now requires that all
1173 but the package name now is passed in as
1174 named parameters. See docs for more info.
1175 - updated docs and tests for this
1177 * Class::MOP::Object
1178 - added &dump method to easily Data::Dumper

1201 - added tests for this
1203 * Class::MOP::Package
1204 - fixed an issue with perl 5.8.1 and how it deals
1205 with symbol tables. The namespace hash is now
1206 always reloaded from the symbol table.
1208 ~ lots of misc. documentation cleanup
1210 0.32 Sat. Aug. 12, 2006
1211 + added Class::MOP::Object so that the
1212 metamodel is more complete (and closer
1213 to what Perl 6 will probably be).

1217 the primary gateway between the metaclass
1218 and the Perl 5 symbol table
1219 - added many tests for this

1226 use Class::MOP::Package methods instead
1228 * Class::MOP::Module
1229 - adding the $:version attribute in the bootstrap
1230 so that Module has a version as an attribute
1231 - see comment in Class::MOP for details
1232 - added the $:authority attribute to this module
1233 as well as an &identifier method, to bring us
1234 ever closer to Perl 6 goodness

1255 - added &set_value and &get_value for getting
1256 the value of the attribute for a particular
1259 0.30 Wed. July 5, 2006
1260 ---------------------------------------
1261 This is the first version of Class::MOP
1262 to introduce the immutable features which
1263 will be used for optimizating the MOP.
1264 This support should still be considered
1265 experimental, but moving towards stability.
1266 ---------------------------------------
1268 * Created Class::MOP::Class::Immutable
1270 * Created the Class::MOP::Package and
1271 Class::MOP::Module classes to more
1272 closely conform to Perl 6's meta-model
1275 - now inherits from Class::MOP::Module
1276 - several methods moved to ::Module and
1277 ::Package and now inherited
1278 - added tests for this
1280 * Class::MOP::Instance
1281 - added an is_inlinable method to allow other
1282 classes to check before they attempt to optimize.
1283 - added an inline_create_instance to inline
1284 instance creation (of course)
1287 - the Class::MOP::Class::*_package_variable
1288 methods are all now methods of Class::MOP::Package
1289 and called *_package_symbol instead. This is
1290 because they are now more general purpose symbol
1291 table manipulation methods.
1293 0.29_02 Thurs. June 22, 2006
1294 ++ DEVELOPER RELEASE ++
1296 - small change in &create so that it behaves

1352 - attribute slot initialization is now the responsibility
1353 of the attribute itself, and construct_instance now
1354 delegates appropriately
1356 * Class::MOP::Attribute
1357 - attribute slot initialization is now the responsibility
1358 of the attribute itself, so we added a method for it
1359 called initialize_instance_slot

1437 shallow clone (see docs for more details)
1438 - added docs and tests
1440 0.10 Tues Feb. 14, 2006
1441 ** This release was mostly about writing more tests and
1442 cleaning out old and dusty code, the MOP should now
1443 be considered "ready to use".
1445 - adding more tests to get coverage up a little higher,
1446 mostly testing errors and edge cases.
1447 - test coverage is now at 99%
1450 - no longer optionally exports to UNIVERSAL::meta or
1451 creates a custom metaclass generator, use the
1452 metaclass pragma instead.
1455 - fixed a number of minor issues which came up in the
1456 error/edge-case tests
1458 * Class::MOP::Attribute
1459 - fixed a number of minor issues which came up in the
1460 error/edge-case tests
1463 - fixing the AttributesWithHistory example, it was broken.

1467 - adding new metaclass pragma to make setting up the
1468 metaclass a little more straightforward
1471 - clean up bootstrapping to include more complete
1472 attribute definitions for Class::MOP::Class and
1473 Class::MOP::Attribute (accessors, readers, writers,
1474 etc.) ... it is redundant, but is useful meta-info
1478 - fixing minor meta-circularity issue with &meta, it
1479 is now more useful for subclasses
1480 - added &get_attribute_map as an accessor for the
1481 hash of attribute meta objects
1482 - &compute_all_applicable_attributes now just returns
1483 the attribute meta-object, rather than the HASH ref
1484 since all the same info can be gotten from the
1485 attribute meta-object itself
1486 - updated docs & tests to reflect
1487 - added &clone_instance method which does a deep clone
1488 of the instance structure created by &construct_instance
1489 - added docs & tests for this
1490 - added Clone as a dependency
1491 - added &new_object and &clone_object convience methods to
1492 return blessed new or cloned instances
1493 - they handle Class::MOP::Class singletons correctly too
1494 - added docs & tests for this
1495 - cleaned up the &constuct_class_instance so that it behaves
1496 more like &construct_instance (and managed the singletons too)
1497 - added the &check_metaclass_compatibility method to make sure
1498 that metaclasses are upward and downward compatible.
1499 - added tests and docs for this
1502 - adjusting code to use the &Class::MOP::Class::meta
1504 - adjusting code to use the metaclass pragma
1506 0.05 Sat Feb. 4, 2006
1508 - added the &attribute_metaclass and &method_metaclass
1509 attributes which contain a metaclass name to use for
1510 attributes/methods respectively
1513 - bootstrap additional attributes for Class::MOP::Class
1516 - adjusted the example code and tests to use the new
1517 &attribute_metaclass feature of Class::MOP::Class
1518 - added new example:
1521 0.04 Fri Feb. 3, 2006
1523 - some documentation suggestions from #perl6
1525 * Class::MOP::Attribute
1526 - improved error messages
1529 - added new examples:
1530 - AttributesWithHistory
1531 - ClassEncapsultedAttributes
1533 0.03 Fri Feb. 3, 2006
1534 - converted to Module::Build instead of EU::MM
1536 * Class::MOP::Attribute
1537 - refactored method generation code
1538 - attributes are now associated with class directly
1541 - refactored the InsideOut example to take advantage
1542 of the Class::MOP::Attribute refactoring
1543 - changed example files to .pod files and hide thier
1544 package names from PAUSE (I don't want to own these
1545 namespaces really, they are just examples)
1547 0.02 Thurs Feb. 2, 2006
1548 - moving examples from t/lib/* to examples/*
1549 - adding POD documentation to the examples
