1 Revision history for Perl extension Class-MOP.
4 - Added rebless_instance_back, which does the inverse of
5 rebless_instance (doy, rafl).
7 0.97_01 Mon, Jan 4, 2010
9 - Internal refactorings to move shared behavior into new "mixin"
10 classes. This made adding some new features to Moose much
13 0.97 Fri, Dec 18, 2009
14 * No code changes, just packaging fixes to make this distro installable.
16 0.96 Fri, Dec 18, 2009
18 - Fixed t/082_get_code_info.t so it passes with bleadperl. (Dave Rolsky)
19 - Add XS & C files to no tabs check (Dave Rolsky)
20 - Convert all tests to done_testing. (Florian Ragwitz)
22 0.95 Wed, Nov 19, 2009
24 - Make is_class_loaded without any arguments fail loudly
26 - Make load_class throw more standard error messages when loading single
27 modules (nothingmuch).
30 - Stop add_method from behaving differently under the debugger
35 - Any method which takes a method name as an argument now allows names
36 which are false (like "0"), but the name must be defined and not be an
37 empty string. (Dave Rolsky)
40 - Deprecated get_attribute_map as a public method. You can use a
41 combination of get_attribute_list and get_attribute instead. (Dave
44 0.94 Tue, Sep 22, 2009
45 * Class::MOP::Attribute
46 - Introduce set_raw_value and get_raw_value, side effect free variants
47 of {get,set}_value. These don't do anything useful in Class::MOP but
48 have different behavior that set_value and get_value for Moose
49 attributes. (nothingmuch)
51 0.93 Tue, Sep 15, 2009
53 - The load_class function just returns true, since it's return value was
54 confusing (either a metaclass object or a class name). It either loads
55 a class or dies trying. In the future, this may change to not return
56 anything, since there's no point in checking its return
57 value. Addresses RT #45883. (Dave Rolsky)
59 * Class::MOP::Class::Trait::Immutable
60 - When throwing an error because of an immutable method, include that
61 method's name. Addresses RT #49680. (Shawn M Moore)
64 - Adding the same sub reference to multiple packages failed to update
65 the method map properly. RT #48985. Reported by Paul Mooney. (Dave
67 - The get_method_map method is now private (and called as
68 _full_method_map or _method_map). The public version is available as a
69 deprecated method. (Dave Rolsky)
71 0.92_01 Thu, Sep 10, 2009
73 - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
76 - Make sure XS code handles magical scalars correctly. (Goro Fuji)
79 - Documented the immutable_options method, which is useful if you need
80 to make a class mutable temporarily, and then nede to restore
81 immutability. (Dave Rolsky)
84 - Deprecated features have been moved to their own module,
85 Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)
90 - Move get_method_map and its various scaffolding into Package. (hdp)
93 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
94 the first argument, rather than just a coderef. (doy)
96 * Class::MOP::Attribute
98 - Allow attribute names to be false (while still requiring them to be
101 0.91 Wed Jul 29, 2009
102 * Class::MOP::Method::Wrapped
103 - Fixing variable usage issues with the patch from previous
104 version, not properly using lexicals in the for
107 0.90 Tue Jul 21, 2009
108 Japan Perl Association has sponsored Goro Fuji to improve startup
109 performance of Class::MOP and Moose. These enhancements may break
110 backwards compatibility if you're doing (or using) complex
111 metaprogramming, so, as always, test your code!
112 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
116 - Anonymous classes were not completely destroyed when they went
117 out of scope, leading to a memory leak. RT #47480. (Goro
121 - The get_method, has_method, and add_method methods no longer
122 use get_method_map. Method objects are instantiated
123 lazily. This significantly improves Class::MOP's load
127 - Inline fewer metaclass-level constructors since the ones we
128 have are perfectly fine. This reduces the number of string
131 * Class::MOP::Method::Wrapped
132 - If a method modifier set $_, this caused the modifier to blow
133 up, because of some weird internals. (Jeremy Stashewsky)
137 * Class::MOP::Class::Immutable::Trait
138 - Made the Trait act like a role with a bunch of "around"
139 modifiers, rather than sticking it in the inheritance
140 hierarchy. This fixes various problems that caused with
141 metaclass compatibility, which broke Fey::ORM.
144 - Allow a blessed code reference as the method body. Fixes a
145 problem interaction with MooseX::Types. (ash)
147 * Class::MOP::Instance
148 - add inline version of rebless_instance_structure. (doy)
149 - change inline_slot_access to use single quotes (gphat)
151 0.88 Tue, Jun 23, 2009
153 - Moved the __INSTANCE__ parameter to _construct_instance from
155 - Fixed some issues involving metaclasses of metaclasses and
158 0.87 Sun, Jun 21, 2009
160 - Made sure to always local-ize $@ and $SIG{__DIE__} before
161 calling an eval. Fixes RT #45973.
164 - Synced docs about immutability with the current reality (which
165 changed back in 0.82_01)
166 - Removed the immutable_transformer method, which had been
167 returning undef since 0.82_01 anyway.
170 - Got rid of tests which needed Moose and improved testing of
171 constructor/destructor inlining warnings. Fixes RT #47119.
173 0.86 Tue, Jun 16, 2009
175 - If you redefined a subroutine at runtime and then wrapped it
176 with a method modifier, the modifier could in some cases wrap
177 the original version of the subroutine. Fixes RT #46957.
180 - make_immutable issues a warning instead of overriding an
181 existing DESTROY method (Dylan William Hardison). Fixes RT
184 0.85 Sat, Jun 6, 2009
185 * Class::MOP::Attribute
186 - Allow default values to be Class::MOP::Methods. (Florian
188 - Test the above. (Rhesa Rozendaal)
189 - Tweak original commit so the intent matches the accepted
190 behavior (Nicholas Perez)
193 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
196 - Add direct_subclasses method (Sartak)
197 - Tests for subclasses and direct_subclasses (Sartak)
198 - subname is no longer used unconditionally in add_method, but
199 only if the code reference's name is '__ANON__' (nothingmuch)
200 - Add a hook for _superclasses_updated (Sartak)
203 - Remove long, old warning about possibly outdated modules
206 0.84 Tue, May 12, 2009
208 - Depend on Text::Exception 0.27 to avoid failing tests ond old
212 - Made is_class_loaded a little stricter. It was reporting that
213 a class was loaded if it merely had an @ISA variable in its
214 stash. Now it checks that the @ISA var has elements in it.
215 - Deprecate in_global_destruction and subname re-exporting
219 - Explicitly use Devel::GlobalDestruction and Sub::Name
222 * Class::MOP::Package
223 - Disable prototype mismatch warnings for add_package_symbol.
226 - Add test for finding methods from $meta->name->meta before immutable,
229 0.83 Mon, April 27, 2009
231 - Fix segfault when calling get_method_map on a metaclass for an empty
234 0.82_02 Fri, April 24, 2009
235 * Class::MOP::Method::Inlined
236 - Don't inline if the expected method is not defined at all (happens with
237 e.g. Moose::Object::_new is the expected method due to an overridden
240 - Some tests were trying to load Class::MOP::Immutable, which
241 was removed in 0.82_01.
243 0.82_01 Thu, April 23, 2009
244 * Class::MOP::Immutable (and others)
245 - Refactor the immutability system to use a pre-defined class
246 for the immutable metaclass of Class::MOP::Class::Immutable::$class
247 - Rather than generating methods into this class every time, use
248 a Trait (basic mixin) to supply the cached methods
249 - Remove the hack that returns the mutable metaclass for
250 metacircularity in order to provide consistent meta-metaclasses
251 for the Moose compatibility handling code
252 (mst broke it, nothingmuch fixed it)
254 0.82 Mon, April 20, 2009
256 - The deprecation wrappers for some renamed methods were not
257 passing arguments to the new method. (nothingmuch)
259 * Class::MOP::Immutable
260 - Warn during immutablization if the local class provides its own
261 constructor, to parallel the warning in Moose when a superclass
262 provides its own constructor (doy)
264 0.81 Tue, April 7, 2009
267 * Class::MOP::Instance
268 * Class::MOP::Attribute
269 * Class::MOP::Method::Accessor
270 * Class::MOP::Method::Constructor
271 - Include stack traces in the deprecation warnings introduced in
272 0.80_01. (Florian Ragwitz)
275 - Avoid c compiler warnings by declaring some unused function
276 arguments. (Florian Ragwitz)
278 0.80_01 Sun, April 5, 2009
280 - Make sure to preserve any compiler flags already defined in
281 Config.pm. Patch by Vincent Pit. RT #44739.
283 * Many methods have been renamed with a leading underscore, and a
284 few have been deprecated entirely. The methods with a leading
285 underscore are considered "internals only". People writing
286 subclasses or extensions to Class::MOP should feel free to
287 override them, but they are not for "public" use.
290 - construct_class_instance => _construct_class_instance (use new_object)
291 - construct_instance => _construct_instance (use new_object)
292 - check_metaclass_compatibility => _check_metaclass_compatibility
293 - create_meta_instance => _create_meta_instance (use get_meta_instance)
294 - clone_instance => _clone_instance (use clone_object)
295 - compute_all_applicable_methods is deprecated, use get_all_methods
296 - compute_all_applicable_attributes is deprecated, use get_all_attributes
298 - Class::MOP::Instance
299 - bless_instance_structure is deprecated and will be removed
303 - create has been renamed to _instantiate_module. This method
304 does not construct an object, it evals some code that
305 creates the relevant package in Perl's symbol table.
307 - Class::MOP::Method::Accessor
308 - initialize_body => _initialize_body (this is always called
309 when an object is constructed)
310 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
312 - Class::MOP::Method::Constructor
313 - initialize_body => _initialize_body (this is always called
314 when an object is constructed)
315 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
316 - attributes => _attributes
317 - meta_instance => _meta_instance
319 0.80 Wed, April 1, 2009
321 - Call user_class->meta in fewer places, with the eventual goal
322 of allowing the user to rename or exclude ->meta
323 altogether. Instead uses Class::MOP::class_of. (Sartak)
326 - New class_of function that should be used to retrieve a
327 metaclass. This is unlike get_metaclass_by_name in that it
328 accepts instances, not just class names. (Sartak)
331 - load_first_existing_class didn't actually load the first
332 existing class; instead, it loaded the first existing and
333 compiling class. It now throws an error if a class exists (in
334 @INC) but fails to compile. (hdp)
338 - we had some semi-buggy code that purported to provide a
339 HAS_ISAREV based on whether mro had get_isarev (due to an
340 oversight, it always returned 1). Since mro and MRO::Compat
341 have always had get_isarev, HAS_ISAREV was pointless. This
342 insight simplified the subclasses method by deleting the
343 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
345 0.79 Fri, March 29, 2009
346 * No changes from 0.78_02.
348 0.78_02 Thu, March 26, 2009
350 * Class::MOP::Immutable
351 - A big backwards-incompatible refactoring of the Immutable API,
352 and the make_immutable/make_mutable pieces of the Class
353 API. The core __PACKAGE__->meta->make_immutable API remains
354 the same, however, so this should only affect the most
358 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
359 has been fixed to be backwards compatible with 5.8.x.
362 - Add a hook for rebless_instance_away (Sartak)
363 - Use blessed instead of ref to get an instance's class name
364 in rebless_instance. (Sartak)
366 0.78_01 Wed, March 18, 2009
368 - Revised and reorganized all of the API documentation. All
369 classes now have (more or less) complete API documentation.
372 * Class::MOP::Instance
373 - Reblessing into a package that supports overloading wasn't
374 properly adding overload magic to the object due to a bug
375 in (at least) 5.8.8. We now use $_[1] directly which seems
376 to set the magic properly. (Sartak)
378 * Class::MOP::Attribute
379 - The process_accessors method is now private. A public alias
380 exists (and will stick around for a few releases), but it
381 warns that calling the public method is deprecated.
383 * Class::MOP::Method::Generated
384 - Removed the new and _new methods, since this is an abstract
385 base class, and all existing subclasses implement their own
389 - Stop is_class_loaded from thinking a class is loaded if it
390 only has an empty GV (Florian Ragwitz).
391 - Add a test for this (Yappo).
392 - Refactor get_all_package_symbols to allow short-circuiting
394 - Use this in is_class_loaded (Florian Ragwitz).
395 - Stop segfaulting when trying to get the name from a sub that's
396 still being compiled (Florian Ragwitz).
397 - Add tests for this (Florian Ragwitz).
398 - Prefix all public symbols with "mop_" (Florian Ragwitz).
399 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
400 - Simplify creating simple xs reader methods (Florian Ragwitz).
401 - Make everything compile with c++ compilers (Florian Ragwitz).
402 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
405 - Remove optional test plans for tests depending on Sub::Name as
406 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
409 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
411 0.78 Mon, February 23, 2009
412 * No changes from 0.77_01
414 0.77_01 Sun, February 22, 2009
416 - This package now requires its XS components. Not using
417 Sub::Name lead to different behavior and bugginess in the pure
418 Perl version of the code. A Moose test would fail when run
419 against the pure Perl version of this code.
421 * Class::MOP::Instance
422 - The inline_* methods now quote attribute names themselves, and
423 don't expect to receive a quoted value.
426 0.77 Sat, February 14, 2009
428 - Avoid assertion errors on debugging perls in is_class_loaded
432 - Fixed various corner cases where is_class_loaded incorrectly
433 returned true for a class that wasn't really loaded. (Dave
437 - Add get_all_method_names (Sartak)
438 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
440 * Class::MOP::Package
441 - Disable deprecated get_all_package_symbols in list
442 context. (Florian Ragwitz)
445 - Make sure we generate a BSD-compatible Makefile (Florian
449 - The misspelled "check_metaclass_compatability" method we've
450 kept around for backwards compat_i_bility will be removed in a
451 near future release. You've been warned.
453 0.76 Thu, January 22, 2009
454 * Class::MOP::Method::Generated
455 - Added new private methods to support code generation, which
456 are being used by Moose and can be used by MooseX
458 - Generated methods are now generated with a #line directive
459 reflecting the source of the generated method. (nothingmuch)
462 - Clarified documentation of methods that return
463 Class::MOP::Method objects. (doy)
466 - Clarified documentation of the metaclass cache methods. (Sartak)
469 - Add test showing how the xs Class::MOP::is_class_loaded can
470 be made to operate differently to the pure perl version (t0m)
472 0.75 Wed, December 31, 2008
474 - A class that was made immutable and then mutable could end up
475 sharing an immutable transformer object
476 (Class::MOP::Immutable) with other classes, leading to all
477 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
479 0.74 Tue, December 25, 2008
481 - Add an xs implementation of Class::MOP::is_class_loaded (closes
482 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
483 - Changed internals to make prehashing of hash keys easier and less
484 error-prone. (Florian Ragwitz)
486 - Fix documentation to show that around modifiers happen on both
487 sides of the modified method. (Dave Rolsky)
489 0.73 Tue, December 16, 2008
491 - Don't use Perl_mro_meta_init. It's not part of the public perl
492 api. Fixes failures to build on Win32 (RT #41750). (Florian
494 * t/082_get_code_info.t
495 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
496 munger anonymous subs when under -d and so making the tests
497 succeed in that case.
499 0.72 Mon, December 8, 2008
500 * Class::MOP::Package
501 - Pass options to _new, so subclass' attributes can be
504 - In the docs, indicate that package_name and name are required
505 when calling ->wrap (Stefan O'Rear)
507 0.71_02 Fri, December 5, 2008
508 * Class::MOP::Immutable
509 - Added a new attribute, inlined_constructor, which is true if
510 the constructor was inlined.
511 * Class::MOP::Package
512 - Make get_all_package_symbols return a hash ref in scalar
513 context and deprecate calling it in list context with a
514 warning. (Florian Ragwitz)
516 - Various improvements and refactoring, making things more robust and
517 easier to maintain. (Florian Ragwitz)
519 0.71_01 Wed, December 3, 2008
521 - Add an "execute" method to invoke the body so
522 we can avoid using the coderef overload (Sartak)
523 * Class::MOP::Immutable
524 - When we memoize methods, get their results lazily
525 to remove some compile-time cost (Sartak)
526 - Small speedup from eliminating several method
529 - Some small internal tweaks to try to reduce the number of
530 times we call get_method_map when bootstrapping the MOP. This
531 might make loading Class::MOP (and Moose) a little
532 faster. (Dave Rolsky)
533 - Implemented an optional XS version of get_method_map. Mostly
534 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
535 help form Florian Ragwitz. (Dave Rolsky)
536 - Make the behaviour of of get_all_package_symbols (and
537 therefore get_method_map) consistent for stub methods. Report
538 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
540 0.71 Wed November 26, 2008
543 - Actual package creation has moved upward from
544 Class to Module so that Moose roles can share
547 0.70_01 Mon, November 19, 2008
549 - Fixes for failures with blead (Florian Ragwitz)
550 - Silenced compiler warnings (Florian Ragwitz)
552 0.70 Fri, November 14, 2008
554 - Fixed an odd corner case where the XS version of
555 get_all_package_symbols could cause a segfault. This only
556 happened with inlined constants in Perl 5.10.0 (Florian
559 0.69 Fri, November 7, 2008
560 * Class::MOP::Method::Wrapped
561 - Added introspection methods for method modifiers (Dave Rolsky)
564 0.68 Fri October 24, 2008
566 - Make load_class require by file name instead of module name.
567 This stops confusing error messages when loading '__PACKAGE__'.
569 - Add load_one_class_of function to enable you to load one of a
570 list of classes, rather than having to call load_class multiple
571 times in an eval. (t0m)
573 0.67 Tue October 14, 2008
575 - Call a method on the class after setting the superclass list
576 so that we can get Perl to detect cycles before MRO::Compat
577 spirals into an infinite loop (sartak)
578 - Reported by Schwern, [rt.cpan.org #39001]
579 - In create(), pass unused options on to initialize()
580 - added test for this
582 0.66 Sat September 20, 2008
583 !! This release has an incompatible change regarding !!
584 introspection of a class's method with Class::MOP::Class !!
587 - We (us maintainers) now run all tests with XS and then without
588 XS, which should help us catch skew between the XS/pure Perl
592 ! The alias_method method has been deprecated. It now simply
593 calls add_method instead. There is no distinction between
594 aliased methods and "real" methods.
596 This means that methods added via alias_method now show up as
597 part of the class's method list/map. This is a backwards
598 incompatible change, but seems unlikely to break any
599 code. Famous last words. (Dave Rolsky)
602 - Fixed the spelling of "compatibility", but we still have a
603 "check_metaclass_compatability" method for backwards
606 0.65 Mon September 1, 2008
607 For those not following the series of dev releases, the changes
608 from 0.64 from 0.65 can mostly be summed up as a lot performance
609 improvements by nothingmuch, including new optional XS versions of
610 some methods. Also, Class::MOP now works _without_ any XS modules,
611 for sad systems without a compiler.
614 - Added name and package_name XS accessors, and make sure all
615 the XS and Perl versions work the same way. (Dave Rolsky)
618 - The XS versions of various methods just returned undef when
619 called class methods, rather than dying like the pure Perl
620 versions. (Dave Rolsky)
622 0.64_07 Fri August 29, 2008
624 - Silenced warnings that managed to break Moose tests when XS
625 was loaded. (Dave Rolsky)
626 - Some XS versions of methods were ignored because of typos in
627 MOP.xs. (Dave Rolsky)
629 0.64_06 Mon August 25, 2008
630 * Class::MOP (MOP.xs)
631 - Another MS VC++ fix, cannot declare a variable in the middle
632 of a scope (Taro Nishino).
634 0.64_05 Sun August 24, 2008
636 - None of the dev releases actually loaded the XS properly, but
637 we silently fell back to the pure Perl version of the
640 * Class::MOP (MOP.xs)
641 - Replaced some code that used functions not available on Visual
642 C++ with some Perl XS API bits (Dave Rolsky).
644 0.64_04 Sat August 23, 2008
646 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
648 * pod.t and pod_coveraget.t
649 - These are no longer shipped with the tarball because of bogus
650 failures from CPAN testers. (Dave Rolsky)
652 0.64_03 Thu August 21, 2008
653 * Class::MOP::Package
654 - Some (legit) code was misparsed by earlier 5.8.x
655 releases. (nothingmuch)
658 - Fix a constant in void context warning (nothingmuch)
660 0.64_02 Thu August 21, 2008
661 * Makefile.PL and Class::MOP
662 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
665 - Add missing prereqs that got lost in the switch away from
668 * Class::MOP::Instance
669 - New method - get_all_attributes (nothingmuch)
671 0.64_01 Wed August 20, 2008
673 - We now check to see if you have a compiler. If you don't, the
674 module installs without some XS bits, but will work the same
675 as with XS. This should make it easier to install on platforms
676 without a compiler (like Windows). (Dave Rolsky)
679 - Perl 6 style attribute naming replaced with sane style ('methods', not
680 '%!methods'). These changes should not impact any existing API uses.
684 - Quite a number of optimizations based on profiling, including
685 allowing constructors to take hash references instead of
686 hashes, duplicating some frequently used code in XS, and
687 making constructors immutable. These changes should not impact
688 any existing API uses. (nothingmuch)
691 - Constructors now respect the meta attributes of their subclasses,
692 facilitating MOP extensibility. More related changes will happen in the
693 next several releases. (nothingmuch)
696 - New method - get_all_methods, replaces the deprecated
697 compute_all_applicable_methods. get_all_attributes provided for
698 consistency (nothingmuch)
699 - New method - wrap_method was refactored out of get_method_map
701 - New API for meta instance invalidation - invalidate_meta_instance,
702 invalidate_meta_instances, add_dependent_meta_instance,
703 remove_dependent_meta_instance, called automatically when attribute
704 definitions change and allows notification of dependent subclasses.
707 0.64 Sun August 3, 2008
708 * Class::MOP::Immutable
709 - fixing subtle edge case in immutable when you
711 - clean up option processing (nothingmuch)
713 * Class::MOP::Instance
714 - inlined initialize slot didn't match
715 non-inlined (nothingmuch)
717 0.63 Mon July 7, 2008
719 - load_class will initialize a metaclass even if
720 the class is already loaded (sartak)
721 - load_class now returns the metaclass instance
722 instead of just 1 (sartak)
725 - better error messages (sartak and Dave Rolsky)
727 0.62 Wed June 18, 2008
728 - in is_class_loaded, recognize scalar references (as opposed to globs) in
729 the symbol table as methods (these are optimized constant subs)
731 0.61 Fri. June 13, 2008
732 - Okay, lets give this another try and see if PAUSE
733 recognizes it correct this time.
735 0.60 Thurs. Jun 12, 2008
736 - Fixed a version number issue by bumping all modules
739 0.59 Thurs. Jun 12, 2008
740 !! Several fixes resulting in yet another 25-30% speedup !!
743 - now stores the instance of the instance
744 metaclass to avoid needless recomputation
745 and deletes it when the cache is blown
746 - introduce methods to query Class::MOP::Class for
747 the options used to make it immutable as well as
748 the proper immutable transformer. (groditi)
750 * Class::MOP::Package
751 - {add, has, get, remove}_package_symbol all
752 now accept a HASH ref argument as well as the
753 string. All internal usages now use the HASH
757 - MOP.xs does sanity checks on the coderef
759 - is_class_loaded check now uses code that
760 was improved in Moose's ClassName type
762 - nonsensical (undef, empty, reference) class
763 names now throw a more direct error in
765 - tests for this and other aspects of
771 Class::MOP::Method::Wrapped
772 Class::MOP::Attribute
773 - switched usage of reftype to ref because
776 0.58 Thurs. May 29, 2008
777 (late night release engineering)--
779 - fixing the version is META.yml, no functional
780 changes in this release
782 0.57 Wed. May 28, 2008
783 !! Several speedups resulting in 20-25% speedups !!
784 || (thanks to konobi, groditi, mst & CataMoose) !!
787 - made get_method_map use list_all_package_symbols
788 instead of manually grabbing each symbol
789 - streamlining &initialize somewhat, since it gets
792 * Class::MOP::Package
793 - made {get, has}_package_symbol not call
795 - inlining a few calls to &name with
796 direct HASH access key access
797 - added get_all_package_symbols to fetch
798 a HASH of items based on a type filter
799 similar to list_all_package_symbols
800 - added tests for this
803 Class::MOP::Method::Constructor
804 Class::MOP::Method::Generated
805 Class::MOP::Method::Accessor
806 - added more descriptive error message to help
807 keep people from wasting time tracking an error
808 that is easily fixed by upgrading.
810 * Class::MOP::Immutable
811 - Don't inline a destructor unless the user actually
813 - added tests for this
815 0.56 Saturday, May 24, 2008
817 - we now get the &check_package_cache_flag
818 function from MRO::Compat
819 - All XS based functionality now has a
820 Pure Perl alternative
821 - the CLASS_MOP_NO_XS environment variable
822 can now be used to force non-XS versions

833 - added the ability to "wrap" methods when
834 making the class immutable
837 - now handling the edge case of ->meta->identifier
838 dying by wrapping add_package_symbol to specifically
839 allow for it to work.
840 - added tests for this
842 * Class::MOP::Attribute
844 Class::MOP::Immutable
845 - any time a method meta object is constructed
846 we make sure to pass the correct package and
847 method name information
850 Class::MOP::Method::Wrapped
851 Class::MOP::Method::Generated
852 Class::MOP::Method::Accessor
853 Class::MOP::Method::Consructor
854 - the &wrap constructor method now requires that a
855 'package_name' and 'name' attribute are passed. This
856 is to help support the no-XS version, and will
857 throw an error if these are not supplied.
858 - all these classes are now bootstrapped properly
859 and now store the package_name and name attributes
862 ~ Build.PL has been removed since the
863 Module::Install support has been removed
865 0.55 Mon. April 28, 2008
866 - All classes now have proper C3 MRO support
867 - added MRO::Compat as a dependency to allow
868 for the C3 MRO support to Just Work in all
872 - rebless_instance now returns the instance
873 it has just blessed, this is mostly to
875 - set the attr correctly in rebless_instance
876 when it has no init_arg
877 - tweaked &linear_isa and &class_precedence_list
878 to support c3 classes.
880 0.54 Fri. March, 14, 2008
883 - making sure that load_class never gets
884 passed a value from @_ or $_ to squash
885 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
888 - make_{immutable,mutable} now return 1
890 - improved error handling in ->create method
891 - rebless_instance now takes extra params which
892 will be used to populate values
893 - added tests for this
896 - localizing the Data::Dumper configurations so
897 that it does not pollute others (RT #33509)
903 Class::MOP::Attribute
904 - these classes no longer define their own ->meta,
905 but instead just inherit from Class::MOP::Object
907 * Class::MOP::Instance
908 Class::MOP::Immutable
909 - these classes now inherit from Class::MOP::Object
912 - fixed the filename length on several
913 test files so we install on VMS better
915 - fixed incorrect use of catdir when it
916 should be catfile (RT #32385)
918 0.53 Thurs. Feb. 14, 1008
919 ~~ several doc. fixes and updates ~~
922 Class::MOP::Method::Constructor

925 to indicate that no constructor args can
926 be passed (thanks to nothingmuch)
927 - added tests for this
928 - added attribute initializer attribute (rjbs)
931 - making this use the new init_arg => undef
932 feature instead of the silly hack from
933 before (thanks to nothingmuch)
935 0.52 Tues. Jan. 22, 2008
937 - fixed bug in rebless_instance
940 * Class::MOP::Method::Constructor
941 - removed assumptions about the existence of
944 0.51 Mon. Jan. 14, 2008
945 ~~~ some misc. doc. fixes ~~~
946 ~~ updated copyright dates ~~
949 - now sets the IS_RUNNING_ON_5_10
950 constant so that we can take advantage
951 of some of the nice bits of 5.10
954 - uses the IS_RUNNING_ON_5_10 flag to
955 optimize the &linearized_isa method
956 and avoid the hack/check for circular
957 inheritence in &class_precedence_list
958 - added rebless_instance method (Sartak)
959 - added tests for this
961 * Class::MOP::Immutable
962 - the immutable class now keeps track of
963 the transformer which immutablized it

967 - added tests for this
969 0.50 Fri. Dec. 21, 2007

983 !! Class::MOP now loads 2 x faster !!
984 !! with XS speedups (thanks konobi) !!
987 - removed the dependency on B
988 - added two XS functions (thanks konobi)
989 - get_code_info($code) which replaces all
990 the B fiddling we were doing with
991 faster/leaner XS level fiddling
992 - check_package_cache_flag($pkg_name) which
993 returns the PL_sub_generation variable to
994 be used to help manage method caching.
997 In 5.10 or greater this will actually
998 use the mro::get_pkg_gen instead to give
999 even more accurate caching information.
1000 blblack++ for that stuff :)
1003 - added the &subclasses method (thanks rlb)
1004 - added the update_package_cache_flag and
1005 reset_package_cache_flag which help keep
1006 track of when we need to re-fetch the
1008 - Several small improvements to take advantage
1009 of the new method map caching features
1011 0.48 Mon. Nov. 26, 2007
1012 * Class::MOP::Attribute
1013 - fixed get_read/write_method to handle the
1014 HASH ref case, which makes the

1016 - added more tests for this
1018 0.47 Sat. Nov. 24, 2007
1019 * Class::MOP::Attribute

1021 - added more tests for this
1023 0.46 Fri. Nov. 23, 2007
1025 - added the linearized_isa method instead of constantly
1026 pruning duplicate classes (this will be even more
1027 useful in the 5.10-compat version coming soon)
1029 * Class::MOP::Attribute
1030 - added the get_read_method_ref and get_write_method_ref
1031 methods which allow you to retrieve a CODE ref which
1032 can always be used to read or write an attribute.
1034 0.45 Thurs. Nov. 13, 2007
1035 * Class::MOP::Attribute
1036 - Fix error message on confess (groditi)
1038 0.44 Thurs. Nov. 13, 2007

1048 - duplicate check into initialize to save a
1049 call through (groditi)
1051 * Class::MOP::Attribute
1052 - Add support for the 'builder' attribute (groditi)

1062 - removed the relevant attributes
1064 * Class::MOP::Method::Constructor
1065 - fixed the cached values we had to be more sane
1066 - made this a subclass of Class::MOP::Method::Generated
1067 - fixed generated constructor so it properly handles
1069 - added tests for this
1070 - added the option to allow for both inlined and
1071 non-inlined constructors.
1072 - Update inlined methods for builder and predicate changes (groditi)
1074 * Class::MOP::Method::Generated
1075 - added this class as an abstract base for the
1076 Class::MOP::Method::{Constructor,Accessor} classes
1077 - added tests for this
1080 - Alter tests (005, 014 020, 021) for new builder addition (groditi)

1090 - alter symbol table handling to deal with 5.8.x and 5.9.x
1093 - Get rid of the crappy workaround from 0.40/41
1095 0.41 Sun. July 15, 2007
1097 Arghh!!! My TODO test didn't work, so I handle
1098 it manually now so that people can use this
1099 with 5.9.5/bleadperl without issue.
1101 0.40 Tues, July 3, 2007
1103 ~ marked a test in 003_methods.t as TODO
1104 for perl 5.9.5 (this test is irrelvant to
1105 the module functioning on 5.9.5 for the most
1108 0.39 Mon. June 18, 2007
1109 * Class::MOP::Immutable
1110 - added make_metaclass_mutable + docs (groditi)
1111 - removed unused variable
1112 - added create_immutable_transformer
1113 necessary for sane overloading of immutable behavior
1114 - tests for this (groditi)
1117 - Immutability can now be undone,
1118 added make_mutable + tests + docs (groditi)
1119 - Massive changes to the way Immutable is done
1120 for details see comments next to make_immutable
1121 This fixes a bug where custom metaclasses broke
1122 when made immutable. We are now keeping one immutable
1123 metaclass instance per metaclass instead of just one
1124 to prevent isa hierarchy corruption. Memory use will go
1125 up, but I suspect it will be neglible.
1126 - New tests added for this behavior. (groditi)
1128 0.38 Thurs. May 31, 2007
1129 ~~ More documentation updates ~~
1131 * Class::MOP::Package
1132 - we now deal with stub methods properly

1137 - added get_read_method and get_write_method
1138 thanks to groditi for this code, tests
1140 - added tests and POD for this
1143 - fixed RT issue #27329, clone object now
1144 handles undef values correctly.
1145 - added tests for this
1146 - Corrected anon-class handling so that they
1147 will not get reaped when instances still
1148 exist which need to reference them. This is
1149 the correct behavior, hopefully this is an
1150 obscure enough feature that there are not too
1151 many work arounds out in the wild.
1152 - added tests for this by groditi
1153 - updated docs to explain this
1156 - load custom metaclasses automatically (thanks groditi)
1157 - added tests for this behavior
1159 0.37 Sat. March 10, 2007

1166 * Class::MOP::Attribute
1167 - default now checks the instance with defined to
1168 avoid setting off bool-overloads (found by Carl Franks)
1172 - bad name in a test, causing meaningless failuress.
1177 ~~ GLOBAL CHANGES ~~
1178 - All attribute names are now consistent and follow Perl 6
1179 style (prefixed with the sigil, and ! as the twigil for
1180 private attrs). This should not affect any code, unless
1181 you broke encapsulation, in which case, it is your problem
1184 !! Class::MOP::Class::Immutable has been removed
1186 * Class::MOP::Method::Constructor
1187 - this has been moved out of Class::MOP::Class::Immutable
1188 and is a proper subclass of Class::MOP::Method now.
1191 - this module now uses Class::MOP::Immutable for the
1192 immutable transformation instead of
1193 Class::MOP::Class::Immutable.
1195 + Class::MOP::Immutable
1196 - this module now controls the transformation from a mutable
1197 to an immutable version of the class. Docs for this will
1198 be coming eventually.
1201 0.36 Sun. Nov. 5, 2006
1203 - added a few 'no warnings' lines to keep annoying
1204 (and meaningless) warnings from chirping during
1208 - some more bootstrapping is now done on the new
1211 * Class::MOP::Class::Immutable
1213 - constructor generation is now handled by
1214 the Class::MOP::Method::Constructor class
1216 * Class::MOP::Method::Constructor
1217 - created this to handle constructor generation
1218 in Class::MOP::Class::Immutable
1220 * Class::MOP::Attribute
1222 - attributes now delegate to the
1223 Class::MOP::Method::Accessor to generate
1226 * Class::MOP::Method::Accessor

1234 on this to come. Comments and patches are
1238 - All Class::MOP::* accessors are no longer
1239 re-generated in the bootstrap, instead
1240 they are aliased from the originals
1241 - fixed tests to reflect
1242 - added Class::MOP::Method (and its subclasses)
1244 - adjusted tests for this
1245 - added the Class::MOP::Instance attributes
1248 * Class::MOP::Method
1250 - methods are no longer blessed CODE refs
1251 but are actual objects which can be CODE-ified
1252 - adjusted tests to compensate
1253 - adjusted docs for this
1256 - changed how methods are dealt with to
1257 encapsulate most of the work into the
1258 &get_method_map method
1259 - made several adjustments for the change
1260 in Class::MOP::Method
1261 - &add_attribute now checks if you are adding
1262 a duplicate name, and properly removes the
1263 old one before installing the new one
1264 - added tests for this
1265 - adjusted docs for this
1267 * Class::MOP::Class::Immutable
1268 - added caching of &get_method_map
1269 - fixed issue with &get_package_symbol

1274 &list_all_package_symbols
1276 0.34 Sat. Aug. 26, 2006
1278 - added the %:methods attribute, which like
1279 the $:version and such just actually goes
1280 to the symbol table to get it's stuff.
1281 However, it makes the MOP more complete.
1283 - The &create method now requires that all
1284 but the package name now is passed in as
1285 named parameters. See docs for more info.
1286 - updated docs and tests for this
1288 * Class::MOP::Object
1289 - added &dump method to easily Data::Dumper

1311 are no longer allowed for defaults
1312 - added tests for this
1314 * Class::MOP::Package
1315 - fixed an issue with perl 5.8.1 and how it deals
1316 with symbol tables. The namespace hash is now
1317 always reloaded from the symbol table.
1319 ~ lots of misc. documentation cleanup
1321 0.32 Sat. Aug. 12, 2006
1322 + added Class::MOP::Object so that the
1323 metamodel is more complete (and closer
1324 to what Perl 6 will probably be).

1328 the primary gateway between the metaclass
1329 and the Perl 5 symbol table
1330 - added many tests for this

1337 use Class::MOP::Package methods instead
1339 * Class::MOP::Module
1340 - adding the $:version attribute in the bootstrap
1341 so that Module has a version as an attribute
1342 - see comment in Class::MOP for details
1343 - added the $:authority attribute to this module
1344 as well as an &identifier method, to bring us
1345 ever closer to Perl 6 goodness
1346 - I have added $AUTHORITY to all the modules
1347 - added tests for this

1363 anywhere within the class hierarchy
1365 * Class::MOP::Attribute
1366 - added &set_value and &get_value for getting
1367 the value of the attribute for a particular
1370 0.30 Wed. July 5, 2006
1371 ---------------------------------------
1372 This is the first version of Class::MOP
1373 to introduce the immutable features which
1374 will be used for optimizating the MOP.
1375 This support should still be considered
1376 experimental, but moving towards stability.
1377 ---------------------------------------
1379 * Created Class::MOP::Class::Immutable
1381 * Created the Class::MOP::Package and
1382 Class::MOP::Module classes to more
1383 closely conform to Perl 6's meta-model
1386 - now inherits from Class::MOP::Module
1387 - several methods moved to ::Module and
1388 ::Package and now inherited
1389 - added tests for this
1391 * Class::MOP::Instance
1392 - added an is_inlinable method to allow other
1393 classes to check before they attempt to optimize.
1394 - added an inline_create_instance to inline
1395 instance creation (of course)
1398 - the Class::MOP::Class::*_package_variable
1399 methods are all now methods of Class::MOP::Package
1400 and called *_package_symbol instead. This is
1401 because they are now more general purpose symbol
1402 table manipulation methods.
1404 0.29_02 Thurs. June 22, 2006

1459 - added tests for this
1460 - added get_all_metaclasses, get_all_metaclass_names
1461 and get_all_metaclass_instances method to allow
1462 access to all the cached metaclass objects.
1463 - attribute slot initialization is now the responsibility
1464 of the attribute itself, and construct_instance now
1465 delegates appropriately
1467 * Class::MOP::Attribute
1468 - attribute slot initialization is now the responsibility
1469 of the attribute itself, so we added a method for it
1470 called initialize_instance_slot

1474 initialize_instance_slot method
1476 0.24 Tues. April 11, 2006

1499 0.21 Wed. March 15, 2006
1501 - fixed issue where metaclasses are reaped from
1502 our cache in global destruction, and so are not
1503 available in DESTORY calls
1505 0.20 Thurs. March 2, 2006
1506 - removed the dependency for Clone since
1507 we no longer to deep-cloning by default.
1509 * Class::MOP::Method
1510 - added &package_name, &name and
1511 &fully_qualified_name methods, some of
1512 which were formerly private subs in
1515 * Class::MOP::Method::Wrapped
1516 - allows for a method to be wrapped with
1517 before, after and around modifiers
1518 - added tests and docs for this feature
1521 - improved &get_package_symbol

1528 - &add_around_method_modifier
1529 - added tests and docs for these

1531 equivalent of SUPER::method_name
1533 0.12 Thurs. Feb 23, 2006
1534 - reduced the dependency on B, no need to always
1538 - added docs to the C3 method dispatch order test
1539 - fixed missing Algorithm::C3 dependency by making
1540 the test skip if it is not installed
1542 0.11 Mon Feb. 20, 2006
1544 - added example of changing method dispatch order to C3
1547 - changed how clone_instance behaves, it now only does a
1548 shallow clone (see docs for more details)
1549 - added docs and tests
1551 0.10 Tues Feb. 14, 2006
1552 ** This release was mostly about writing more tests and
1553 cleaning out old and dusty code, the MOP should now
1554 be considered "ready to use".
1556 - adding more tests to get coverage up a little higher,
1557 mostly testing errors and edge cases.
1558 - test coverage is now at 99%
1561 - no longer optionally exports to UNIVERSAL::meta or
1562 creates a custom metaclass generator, use the
1563 metaclass pragma instead.
1566 - fixed a number of minor issues which came up in the
1567 error/edge-case tests
1569 * Class::MOP::Attribute
1570 - fixed a number of minor issues which came up in the
1571 error/edge-case tests
1574 - fixing the AttributesWithHistory example, it was broken.
1576 0.06 Thurs Feb. 9, 2006
1578 - adding new metaclass pragma to make setting up the
1579 metaclass a little more straightforward
1582 - clean up bootstrapping to include more complete
1583 attribute definitions for Class::MOP::Class and
1584 Class::MOP::Attribute (accessors, readers, writers,
1585 etc.) ... it is redundant, but is useful meta-info
1589 - fixing minor meta-circularity issue with &meta, it
1590 is now more useful for subclasses
1591 - added &get_attribute_map as an accessor for the
1592 hash of attribute meta objects
1593 - &compute_all_applicable_attributes now just returns
1594 the attribute meta-object, rather than the HASH ref
1595 since all the same info can be gotten from the
1596 attribute meta-object itself
1597 - updated docs & tests to reflect
1598 - added &clone_instance method which does a deep clone
1599 of the instance structure created by &construct_instance
1600 - added docs & tests for this
1601 - added Clone as a dependency
1602 - added &new_object and &clone_object convience methods to
1603 return blessed new or cloned instances
1604 - they handle Class::MOP::Class singletons correctly too
1605 - added docs & tests for this
1606 - cleaned up the &constuct_class_instance so that it behaves
1607 more like &construct_instance (and managed the singletons too)
1608 - added the &check_metaclass_compatibility method to make sure
1609 that metaclasses are upward and downward compatible.
1610 - added tests and docs for this
1613 - adjusting code to use the &Class::MOP::Class::meta
1615 - adjusting code to use the metaclass pragma
1617 0.05 Sat Feb. 4, 2006
1619 - added the &attribute_metaclass and &method_metaclass
1620 attributes which contain a metaclass name to use for
1621 attributes/methods respectively
1624 - bootstrap additional attributes for Class::MOP::Class
1627 - adjusted the example code and tests to use the new
1628 &attribute_metaclass feature of Class::MOP::Class
1629 - added new example:
1632 0.04 Fri Feb. 3, 2006
1634 - some documentation suggestions from #perl6
1636 * Class::MOP::Attribute

1652 - refactored the InsideOut example to take advantage
1653 of the Class::MOP::Attribute refactoring
1654 - changed example files to .pod files and hide thier
1655 package names from PAUSE (I don't want to own these
1656 namespaces really, they are just examples)
1658 0.02 Thurs Feb. 2, 2006
1659 - moving examples from t/lib/* to examples/*
1660 - adding POD documentation to the examples
