1 Revision history for Perl extension Class-MOP.
5 - Moved the __INSTANCE__ parameter to _construct_instance from
7 - Fixed some issues involving metaclasses of metaclasses and
10 0.87 Sun, Jun 21, 2009
12 - Made sure to always local-ize $@ and $SIG{__DIE__} before
13 calling an eval. Fixes RT #45973.
16 - Synced docs about immutability with the current reality (which
17 changed back in 0.82_01)
18 - Removed the immutable_transformer method, which had been
19 returning undef since 0.82_01 anyway.
22 - Got rid of tests which needed Moose and improved testing of
23 constructor/destructor inlining warnings. Fixes RT #47119.
25 0.86 Tue, Jun 16, 2009
27 - If you redefined a subroutine at runtime and then wrapped it
28 with a method modifier, the modifier could in some cases wrap
29 the original version of the subroutine. Fixes RT #46957.
32 - make_immutable issues a warning instead of overriding an
33 existing DESTROY method (Dylan William Hardison). Fixes RT
37 * Class::MOP::Attribute
38 - Allow default values to be Class::MOP::Methods. (Florian
40 - Test the above. (Rhesa Rozendaal)
41 - Tweak original commit so the intent matches the accepted
42 behavior (Nicholas Perez)
45 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
48 - Add direct_subclasses method (Sartak)
49 - Tests for subclasses and direct_subclasses (Sartak)
50 - subname is no longer used unconditionally in add_method, but
51 only if the code reference's name is '__ANON__' (nothingmuch)
52 - Add a hook for _superclasses_updated (Sartak)
55 - Remove long, old warning about possibly outdated modules
58 0.84 Tue, May 12, 2009
60 - Depend on Text::Exception 0.27 to avoid failing tests ond old
64 - Made is_class_loaded a little stricter. It was reporting that
65 a class was loaded if it merely had an @ISA variable in its
66 stash. Now it checks that the @ISA var has elements in it.
67 - Deprecate in_global_destruction and subname re-exporting
71 - Explicitly use Devel::GlobalDestruction and Sub::Name
75 - Disable prototype mismatch warnings for add_package_symbol.
78 0.83 Mon, April 27, 2009
80 - Fix segfault when calling get_method_map on a metaclass for an empty
83 0.82_02 Fri, April 24, 2009
84 * Class::MOP::Method::Inlined
85 - Don't inline if the expected method is not defined at all (happens with
86 e.g. Moose::Object::_new is the expected method due to an overridden
89 - Some tests were trying to load Class::MOP::Immutable, which
90 was removed in 0.82_01.
92 0.82_01 Thu, April 23, 2009
93 * Class::MOP::Immutable (and others)
94 - Refactor the immutability system to use a pre-defined class
95 for the immutable metaclass of Class::MOP::Class::Immutable::$class
96 - Rather than generating methods into this class every time, use
97 a Trait (basic mixin) to supply the cached methods
98 - Remove the hack that returns the mutable metaclass for
99 metacircularity in order to provide consistent meta-metaclasses
100 for the Moose compatibility handling code
101 (mst broke it, nothingmuch fixed it)
103 0.82 Mon, April 20, 2009
105 - The deprecation wrappers for some renamed methods were not
106 passing arguments to the new method. (nothingmuch)
108 * Class::MOP::Immutable
109 - Warn during immutablization if the local class provides its own
110 constructor, to parallel the warning in Moose when a superclass
111 provides its own constructor (doy)
113 0.81 Tue, April 7, 2009
116 * Class::MOP::Instance
117 * Class::MOP::Attribute
118 * Class::MOP::Method::Accessor
119 * Class::MOP::Method::Constructor
120 - Include stack traces in the deprecation warnings introduced in
121 0.80_01. (Florian Ragwitz)
124 - Avoid c compiler warnings by declaring some unused function
125 arguments. (Florian Ragwitz)
127 0.80_01 Sun, April 5, 2009
129 - Make sure to preserve any compiler flags already defined in
130 Config.pm. Patch by Vincent Pit. RT #44739.
132 * Many methods have been renamed with a leading underscore, and a
133 few have been deprecated entirely. The methods with a leading
134 underscore are consider "internals only". People writing
135 subclasses or extensions to Class::MOP should feel free to
136 override them, but they are not for "public" use.
139 - construct_class_instance => _construct_class_instance (use new_object)
140 - construct_instance => _construct_instance (use new_object)
141 - check_metaclass_compatibility => _check_metaclass_compatibility
142 - create_meta_instance => _create_meta_instance (use get_meta_instance)
143 - clone_instance => _clone_instance (use clone_object)
144 - compute_all_applicable_methods is deprecated, use get_all_methods
145 - compute_all_applicable_attributes is deprecated, use get_all_attributes
147 - Class::MOP::Instance
148 - bless_instance_structure is deprecated and will be removed
152 - create has been renamed to _instantiate_module. This method
153 does not construct an object, it evals some code that
154 creates the relevant package in Perl's symbol table.
156 - Class::MOP::Method::Accessor
157 - initialize_body => _initialize_body (this is always called
158 when an object is constructed)
159 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
161 - Class::MOP::Method::Constructor
162 - initialize_body => _initialize_body (this is always called
163 when an object is constructed)
164 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
165 - attributes => _attributes
166 - meta_instance => _meta_instance
168 0.80 Wed, April 1, 2009
170 - Call user_class->meta in fewer places, with the eventual goal
171 of allowing the user to rename or exclude ->meta
172 altogether. Instead uses Class::MOP::class_of. (Sartak)
175 - New class_of function that should be used to retrieve a
176 metaclass. This is unlike get_metaclass_by_name in that it
177 accepts instances, not just class names. (Sartak)
180 - load_first_existing_class didn't actually load the first
181 existing class; instead, it loaded the first existing and
182 compiling class. It now throws an error if a class exists (in
183 @INC) but fails to compile. (hdp)
187 - we had some semi-buggy code that purported to provide a
188 HAS_ISAREV based on whether mro had get_isarev (due to an
189 oversight, it always returned 1). Since mro and MRO::Compat
190 have always had get_isarev, HAS_ISAREV was pointless. This
191 insight simplified the subclasses method by deleting the
192 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
194 0.79 Fri, March 29, 2009
195 * No changes from 0.78_02.
197 0.78_02 Thu, March 26, 2009
199 * Class::MOP::Immutable
200 - A big backwards-incompatible refactoring of the Immutable API,
201 and the make_immutable/make_mutable pieces of the Class
202 API. The core __PACKAGE__->meta->make_immutable API remains
203 the same, however, so this should only affect the most
207 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
208 has been fixed to be backwards compatible with 5.8.x.
211 - Add a hook for rebless_instance_away (Sartak)
212 - Use blessed instead of ref to get an instance's class name
213 in rebless_instance. (Sartak)
215 0.78_01 Wed, March 18, 2009
217 - Revised and reorganized all of the API documentation. All
218 classes now have (more or less) complete API documentation.
221 * Class::MOP::Instance
222 - Reblessing into a package that supports overloading wasn't
223 properly adding overload magic to the object due to a bug
224 in (at least) 5.8.8. We now use $_[1] directly which seems
225 to set the magic properly. (Sartak)
227 * Class::MOP::Attribute
228 - The process_accessors method is now private. A public alias
229 exists (and will stick around for a few releases), but it
230 warns that calling the public method is deprecated.
232 * Class::MOP::Method::Generated
233 - Removed the new and _new methods, since this is an abstract
234 base class, and all existing subclasses implement their own
238 - Stop is_class_loaded from thinking a class is loaded if it
239 only has an empty GV (Florian Ragwitz).
240 - Add a test for this (Yappo).
241 - Refactor get_all_package_symbols to allow short-circuiting
243 - Use this in is_class_loaded (Florian Ragwitz).
244 - Stop segfaulting when trying to get the name from a sub that's
245 still being compiled (Florian Ragwitz).
246 - Add tests for this (Florian Ragwitz).
247 - Prefix all public symbols with "mop_" (Florian Ragwitz).
248 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
249 - Simplify creating simple xs reader methods (Florian Ragwitz).
250 - Make everything compile with c++ compilers (Florian Ragwitz).
251 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
254 - Remove optional test plans for tests depending on Sub::Name as
255 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
258 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
260 0.78 Mon, February 23, 2009
261 * No changes from 0.77_01
263 0.77_01 Sun, February 22, 2009
265 - This package now requires its XS components. Not using
266 Sub::Name lead to different behavior and bugginess in the pure
267 Perl version of the code. A Moose test would fail when run
268 against the pure Perl version of this code.
270 * Class::MOP::Instance
271 - The inline_* methods now quote attribute names themselves, and
272 don't expect to receive a quoted value.
275 0.77 Sat, February 14, 2009
277 - Avoid assertion errors on debugging perls in is_class_loaded
281 - Fixed various corner cases where is_class_loaded incorrectly
282 returned true for a class that wasn't really loaded. (Dave
286 - Add get_all_method_names (Sartak)
287 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
289 * Class::MOP::Package
290 - Disable deprecated get_all_package_symbols in list
291 context. (Florian Ragwitz)
294 - Make sure we generate a BSD-compatible Makefile (Florian
298 - The misspelled "check_metaclass_compatability" method we've
299 kept around for backwards compat_i_bility will be removed in a
300 near future release. You've been warned.
302 0.76 Thu, January 22, 2009
303 * Class::MOP::Method::Generated
304 - Added new private methods to support code generation, which
305 are being used by Moose and can be used by MooseX
307 - Generated methods are now generated with a #line directive
308 reflecting the source of the generated method. (nothingmuch)
311 - Clarified documentation of methods that return
312 Class::MOP::Method objects. (doy)
315 - Clarified documentation of the metaclass cache methods. (Sartak)
318 - Add test showing how the xs Class::MOP::is_class_loaded can
319 be made to operate differently to the pure perl version (t0m)
321 0.75 Wed, December 31, 2008
323 - A class that was made immutable and then mutable could end up
324 sharing an immutable transformer object
325 (Class::MOP::Immutable) with other classes, leading to all
326 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
328 0.74 Tue, December 25, 2008
330 - Add an xs implementation of Class::MOP::is_class_loaded (closes
331 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
332 - Changed internals to make prehashing of hash keys easier and less
333 error-prone. (Florian Ragwitz)
335 - Fix documentation to show that around modifiers happen on both
336 sides of the modified method. (Dave Rolsky)
338 0.73 Tue, December 16, 2008
340 - Don't use Perl_mro_meta_init. It's not part of the public perl
341 api. Fixes failures to build on Win32 (RT #41750). (Florian
343 * t/082_get_code_info.t
344 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
345 munger anonymous subs when under -d and so making the tests
346 succeed in that case.
348 0.72 Mon, December 8, 2008
349 * Class::MOP::Package
350 - Pass options to _new, so subclass' attributes can be
353 - In the docs, indicate that package_name and name are required
354 when calling ->wrap (Stefan O'Rear)
356 0.71_02 Fri, December 5, 2008
357 * Class::MOP::Immutable
358 - Added a new attribute, inlined_constructor, which is true if
359 the constructor was inlined.
360 * Class::MOP::Package
361 - Make get_all_package_symbols return a hash ref in scalar
362 context and deprecate calling it in list context with a
363 warning. (Florian Ragwitz)
365 - Various improvements and refactoring, making things more robust and
366 easier to maintain. (Florian Ragwitz)
368 0.71_01 Wed, December 3, 2008
370 - Add an "execute" method to invoke the body so
371 we can avoid using the coderef overload (Sartak)
372 * Class::MOP::Immutable
373 - When we memoize methods, get their results lazily
374 to remove some compile-time cost (Sartak)
375 - Small speedup from eliminating several method
378 - Some small internal tweaks to try to reduce the number of
379 times we call get_method_map when bootstrapping the MOP. This
380 might make loading Class::MOP (and Moose) a little
381 faster. (Dave Rolsky)
382 - Implemented an optional XS version of get_method_map. Mostly
383 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
384 help form Florian Ragwitz. (Dave Rolsky)
385 - Make the behaviour of of get_all_package_symbols (and
386 therefore get_method_map) consistent for stub methods. Report
387 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
389 0.71 Wed November 26, 2008
392 - Actual package creation has moved upward from
393 Class to Module so that Moose roles can share
396 0.70_01 Mon, November 19, 2008
398 - Fixes for failures with blead (Florian Ragwitz)
399 - Silenced compiler warnings (Florian Ragwitz)
401 0.70 Fri, November 14, 2008
403 - Fixed an odd corner case where the XS version of
404 get_all_package_symbols could cause a segfault. This only
405 happened with inlined constants in Perl 5.10.0 (Florian
408 0.69 Fri, November 7, 2008
409 * Class::MOP::Method::Wrapped
410 - Added introspection methods for method modifiers (Dave Rolsky)
413 0.68 Fri October 24, 2008
415 - Make load_class require by file name instead of module name.
416 This stops confusing error messages when loading '__PACKAGE__'.
418 - Add load_one_class_of function to enable you to load one of a
419 list of classes, rather than having to call load_class multiple
420 times in an eval. (t0m)
422 0.67 Tue October 14, 2008
424 - Call a method on the class after setting the superclass list
425 so that we can get Perl to detect cycles before MRO::Compat
426 spirals into an infinite loop (sartak)
427 - Reported by Schwern, [rt.cpan.org #39001]
428 - In create(), pass unused options on to initialize()
429 - added test for this
431 0.66 Sat September 20, 2008
432 !! This release has an incompatible change regarding !!
433 introspection of a class's method with Class::MOP::Class !!
436 - We (us maintainers) now run all tests with XS and then without
437 XS, which should help us catch skew between the XS/pure Perl
441 ! The alias_method method has been deprecated. It now simply
442 calls add_method instead. There is no distinction between
443 aliased methods and "real" methods.
445 This means that methods added via alias_method now show up as
446 part of the class's method list/map. This is a backwards
447 incompatible change, but seems unlikely to break any
448 code. Famous last words. (Dave Rolsky)
451 - Fixed the spelling of "compatibility", but we still have a
452 "check_metaclass_compatability" method for backwards
455 0.65 Mon September 1, 2008
456 For those not following the series of dev releases, the changes
457 from 0.64 from 0.65 can mostly be summed up as a lot performance
458 improvements by nothingmuch, including new optional XS versions of
459 some methods. Also, Class::MOP now works _without_ any XS modules,
460 for sad systems without a compiler.
463 - Added name and package_name XS accessors, and make sure all
464 the XS and Perl versions work the same way. (Dave Rolsky)
467 - The XS versions of various methods just returned undef when
468 called class methods, rather than dying like the pure Perl
469 versions. (Dave Rolsky)
471 0.64_07 Fri August 29, 2008
473 - Silenced warnings that managed to break Moose tests when XS
474 was loaded. (Dave Rolsky)
475 - Some XS versions of methods were ignored because of typos in
476 MOP.xs. (Dave Rolsky)
478 0.64_06 Mon August 25, 2008
479 * Class::MOP (MOP.xs)
480 - Another MS VC++ fix, cannot declare a variable in the middle
481 of a scope (Taro Nishino).
483 0.64_05 Sun August 24, 2008
485 - None of the dev releases actually loaded the XS properly, but
486 we silently fell back to the pure Perl version of the
489 * Class::MOP (MOP.xs)
490 - Replaced some code that used functions not available on Visual
491 C++ with some Perl XS API bits (Dave Rolsky).
493 0.64_04 Sat August 23, 2008
495 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
497 * pod.t and pod_coveraget.t
498 - These are no longer shipped with the tarball because of bogus
499 failures from CPAN testers. (Dave Rolsky)
501 0.64_03 Thu August 21, 2008
502 * Class::MOP::Package
503 - Some (legit) code was misparsed by earlier 5.8.x
504 releases. (nothingmuch)
507 - Fix a constant in void context warning (nothingmuch)
509 0.64_02 Thu August 21, 2008
510 * Makefile.PL and Class::MOP
511 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
514 - Add missing prereqs that got lost in the switch away from
517 * Class::MOP::Instance
518 - New method - get_all_attributes (nothingmuch)
520 0.64_01 Wed August 20, 2008
522 - We now check to see if you have a compiler. If you don't, the
523 module installs without some XS bits, but will work the same
524 as with XS. This should make it easier to install on platforms
525 without a compiler (like Windows). (Dave Rolsky)
528 - Perl 6 style attribute naming replaced with sane style ('methods', not
529 '%!methods'). These changes should not impact any existing API uses.
533 - Quite a number of optimizations based on profiling, including
534 allowing constructors to take hash references instead of
535 hashes, duplicating some frequently used code in XS, and
536 making constructors immutable. These changes should not impact
537 any existing API uses. (nothingmuch)
540 - Constructors now respect the meta attributes of their subclasses,
541 facilitating MOP extensibility. More related changes will happen in the
542 next several releases. (nothingmuch)
545 - New method - get_all_methods, replaces the deprecated
546 compute_all_applicable_methods. get_all_attributes provided for
547 consistency (nothingmuch)
548 - New method - wrap_method was refactored out of get_method_map
550 - New API for meta instance invalidation - invalidate_meta_instance,
551 invalidate_meta_instances, add_dependent_meta_instance,
552 remove_dependent_meta_instance, called automatically when attribute
553 definitions change and allows notification of dependent subclasses.
556 0.64 Sun August 3, 2008
557 * Class::MOP::Immutable
558 - fixing subtle edge case in immutable when you
560 - clean up option processing (nothingmuch)
562 * Class::MOP::Instance
563 - inlined initialize slot didn't match
564 non-inlined (nothingmuch)
566 0.63 Mon July 7, 2008
568 - load_class will initialize a metaclass even if
569 the class is already loaded (sartak)
570 - load_class now returns the metaclass instance
571 instead of just 1 (sartak)
574 - better error messages (sartak and Dave Rolsky)
576 0.62 Wed June 18, 2008
577 - in is_class_loaded, recognize scalar references (as opposed to globs) in
578 the symbol table as methods (these are optimized constant subs)
580 0.61 Fri. June 13, 2008
581 - Okay, lets give this another try and see if PAUSE
582 recognizes it correct this time.
584 0.60 Thurs. Jun 12, 2008
585 - Fixed a version number issue by bumping all modules
588 0.59 Thurs. Jun 12, 2008
589 !! Several fixes resulting in yet another 25-30% speedup !!
592 - now stores the instance of the instance
593 metaclass to avoid needless recomputation
594 and deletes it when the cache is blown
595 - introduce methods to query Class::MOP::Class for
596 the options used to make it immutable as well as
597 the proper immutable transformer. (groditi)
599 * Class::MOP::Package
600 - {add, has, get, remove}_package_symbol all
601 now accept a HASH ref argument as well as the
602 string. All internal usages now use the HASH
606 - MOP.xs does sanity checks on the coderef
608 - is_class_loaded check now uses code that
609 was improved in Moose's ClassName type
611 - nonsensical (undef, empty, reference) class
612 names now throw a more direct error in
614 - tests for this and other aspects of
620 Class::MOP::Method::Wrapped
621 Class::MOP::Attribute
622 - switched usage of reftype to ref because
625 0.58 Thurs. May 29, 2008
626 (late night release engineering)--
628 - fixing the version is META.yml, no functional
629 changes in this release
631 0.57 Wed. May 28, 2008
632 !! Several speedups resulting in 20-25% speedups !!
633 || (thanks to konobi, groditi, mst & CataMoose) !!
636 - made get_method_map use list_all_package_symbols
637 instead of manually grabbing each symbol
638 - streamlining &initialize somewhat, since it gets
641 * Class::MOP::Package
642 - made {get, has}_package_symbol not call
644 - inlining a few calls to &name with
645 direct HASH access key access
646 - added get_all_package_symbols to fetch
647 a HASH of items based on a type filter
648 similar to list_all_package_symbols
649 - added tests for this
652 Class::MOP::Method::Constructor
653 Class::MOP::Method::Generated
654 Class::MOP::Method::Accessor
655 - added more descriptive error message to help
656 keep people from wasting time tracking an error
657 that is easily fixed by upgrading.
659 * Class::MOP::Immutable
660 - Don't inline a destructor unless the user actually
662 - added tests for this
664 0.56 Saturday, May 24, 2008
666 - we now get the &check_package_cache_flag
667 function from MRO::Compat
668 - All XS based functionality now has a
669 Pure Perl alternative
670 - the CLASS_MOP_NO_XS environment variable
671 can now be used to force non-XS versions
674 * Class::MOP::Attribute
675 - add has_read_method and has_write_method
676 - get_{read,write}_method_ref now wraps the
677 anon-sub ref in the method metaclass when
679 - added tests for this
681 * Class::MOP::Immutable
682 - added the ability to "wrap" methods when
683 making the class immutable
686 - now handling the edge case of ->meta->identifier
687 dying by wrapping add_package_symbol to specifically
688 allow for it to work.
689 - added tests for this
691 * Class::MOP::Attribute
693 Class::MOP::Immutable
694 - any time a method meta object is constructed
695 we make sure to pass the correct package and
696 method name information
699 Class::MOP::Method::Wrapped
700 Class::MOP::Method::Generated
701 Class::MOP::Method::Accessor
702 Class::MOP::Method::Consructor
703 - the &wrap constructor method now requires that a
704 'package_name' and 'name' attribute are passed. This
705 is to help support the no-XS version, and will
706 throw an error if these are not supplied.
707 - all these classes are now bootstrapped properly
708 and now store the package_name and name attributes
711 ~ Build.PL has been removed since the
712 Module::Install support has been removed
714 0.55 Mon. April 28, 2008
715 - All classes now have proper C3 MRO support
716 - added MRO::Compat as a dependency to allow
717 for the C3 MRO support to Just Work in all
721 - rebless_instance now returns the instance
722 it has just blessed, this is mostly to
724 - set the attr correctly in rebless_instance
725 when it has no init_arg
726 - tweaked &linear_isa and &class_precedence_list
727 to support c3 classes.
729 0.54 Fri. March, 14, 2008
732 - making sure that load_class never gets
733 passed a value from @_ or $_ to squash
734 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
737 - make_{immutable,mutable} now return 1
739 - improved error handling in ->create method
740 - rebless_instance now takes extra params which
741 will be used to populate values
742 - added tests for this
745 - localizing the Data::Dumper configurations so
746 that it does not pollute others (RT #33509)
752 Class::MOP::Attribute
753 - these classes no longer define their own ->meta,
754 but instead just inherit from Class::MOP::Object
756 * Class::MOP::Instance
757 Class::MOP::Immutable
758 - these classes now inherit from Class::MOP::Object
761 - fixed the filename length on several
762 test files so we install on VMS better
764 - fixed incorrect use of catdir when it
765 should be catfile (RT #32385)

768 ~~ several doc. fixes and updates ~~
771 Class::MOP::Method::Constructor
772 Class::MOP::Attribute
773 - making init_arg accept an undefined value
774 to indicate that no constructor args can
775 be passed (thanks to nothingmuch)
776 - added tests for this
777 - added attribute initializer attribute (rjbs)
780 - making this use the new init_arg => undef
781 feature instead of the silly hack from
782 before (thanks to nothingmuch)
784 0.52 Tues. Jan. 22, 2008
786 - fixed bug in rebless_instance
789 * Class::MOP::Method::Constructor
790 - removed assumptions about the existence of
793 0.51 Mon. Jan. 14, 2008
794 ~~~ some misc. doc. fixes ~~~
795 ~~ updated copyright dates ~~
798 - now sets the IS_RUNNING_ON_5_10
799 constant so that we can take advantage
800 of some of the nice bits of 5.10
803 - uses the IS_RUNNING_ON_5_10 flag to
804 optimize the &linearized_isa method
805 and avoid the hack/check for circular
806 inheritence in &class_precedence_list
807 - added rebless_instance method (Sartak)
808 - added tests for this
810 * Class::MOP::Immutable
811 - the immutable class now keeps track of
812 the transformer which immutablized it

825 * Class::MOP::Immutable
826 - fixed a bug (see above)
828 * Class::MOP::Attribute
831 0.49 Fri. Dec. 14, 2007
832 !! Class::MOP now loads 2 x faster !!
833 !! with XS speedups (thanks konobi) !!
836 - removed the dependency on B
837 - added two XS functions (thanks konobi)
838 - get_code_info($code) which replaces all
839 the B fiddling we were doing with
840 faster/leaner XS level fiddling
841 - check_package_cache_flag($pkg_name) which
842 returns the PL_sub_generation variable to
843 be used to help manage method caching.
846 In 5.10 or greater this will actually
847 use the mro::get_pkg_gen instead to give
848 even more accurate caching information.
849 blblack++ for that stuff :)
852 - added the &subclasses method (thanks rlb)
853 - added the update_package_cache_flag and
854 reset_package_cache_flag which help keep
855 track of when we need to re-fetch the
857 - Several small improvements to take advantage
858 of the new method map caching features
860 0.48 Mon. Nov. 26, 2007
861 * Class::MOP::Attribute
862 - fixed get_read/write_method to handle the

872 0.46 Fri. Nov. 23, 2007
874 - added the linearized_isa method instead of constantly
875 pruning duplicate classes (this will be even more
876 useful in the 5.10-compat version coming soon)
878 * Class::MOP::Attribute
879 - added the get_read_method_ref and get_write_method_ref
880 methods which allow you to retrieve a CODE ref which
881 can always be used to read or write an attribute.
883 0.45 Thurs. Nov. 13, 2007
884 * Class::MOP::Attribute
885 - Fix error message on confess (groditi)
887 0.44 Thurs. Nov. 13, 2007
888 - Apparently I didn't make dist correctly (groditi)
890 0.43 Thurs. Nov. 13, 2007
892 - Add support for the 'builder' attribute (groditi)
895 - optimise metaclass-already-exists check in
896 construct_class_instance (groditi)
897 - duplicate check into initialize to save a
898 call through (groditi)
900 * Class::MOP::Attribute
901 - Add support for the 'builder' attribute (groditi)
902 - Make predicates check for the existence of a value, not whether
903 it is defined (groditi)
905 * Class::MOP::Instance
906 - Make predicates check for the existence of a value, not whether
907 it is defined (groditi)
909 * Class::MOP::Method::Accessor
910 - made this a subclass of Class::MOP::Method::Generated
911 - removed the relevant attributes
913 * Class::MOP::Method::Constructor
914 - fixed the cached values we had to be more sane
915 - made this a subclass of Class::MOP::Method::Generated
916 - fixed generated constructor so it properly handles
918 - added tests for this
919 - added the option to allow for both inlined and
920 non-inlined constructors.
921 - Update inlined methods for builder and predicate changes (groditi)
923 * Class::MOP::Method::Generated
924 - added this class as an abstract base for the
925 Class::MOP::Method::{Constructor,Accessor} classes
926 - added tests for this
929 - Alter tests (005, 014 020, 021) for new builder addition (groditi)

938 * Class::MOP::Package
939 - alter symbol table handling to deal with 5.8.x and 5.9.x
942 - Get rid of the crappy workaround from 0.40/41
944 0.41 Sun. July 15, 2007
946 Arghh!!! My TODO test didn't work, so I handle
947 it manually now so that people can use this
948 with 5.9.5/bleadperl without issue.
950 0.40 Tues, July 3, 2007
952 ~ marked a test in 003_methods.t as TODO
953 for perl 5.9.5 (this test is irrelvant to
954 the module functioning on 5.9.5 for the most
957 0.39 Mon. June 18, 2007
958 * Class::MOP::Immutable
959 - added make_metaclass_mutable + docs (groditi)
960 - removed unused variable
961 - added create_immutable_transformer
962 necessary for sane overloading of immutable behavior
963 - tests for this (groditi)
966 - Immutability can now be undone,
967 added make_mutable + tests + docs (groditi)
968 - Massive changes to the way Immutable is done
969 for details see comments next to make_immutable
970 This fixes a bug where custom metaclasses broke
971 when made immutable. We are now keeping one immutable
972 metaclass instance per metaclass instead of just one
973 to prevent isa hierarchy corruption. Memory use will go
974 up, but I suspect it will be neglible.
975 - New tests added for this behavior. (groditi)
977 0.38 Thurs. May 31, 2007
978 ~~ More documentation updates ~~
980 * Class::MOP::Package
981 - we now deal with stub methods properly

983 - fixed some tests failing on 5.9.5 (thanks blblack)
985 * Class::MOP::Attribute
986 - added get_read_method and get_write_method
987 thanks to groditi for this code, tests
989 - added tests and POD for this
992 - fixed RT issue #27329, clone object now
993 handles undef values correctly.
994 - added tests for this
995 - Corrected anon-class handling so that they
996 will not get reaped when instances still
997 exist which need to reference them. This is
998 the correct behavior, hopefully this is an
999 obscure enough feature that there are not too
1000 many work arounds out in the wild.
1001 - added tests for this by groditi
1002 - updated docs to explain this
1005 - load custom metaclasses automatically (thanks groditi)
1006 - added tests for this behavior
1008 0.37 Sat. March 10, 2007

1015 * Class::MOP::Attribute
1016 - default now checks the instance with defined to
1017 avoid setting off bool-overloads (found by Carl Franks)
1021 - bad name in a test, causing meaningless failuress.
1026 ~~ GLOBAL CHANGES ~~
1027 - All attribute names are now consistent and follow Perl 6
1028 style (prefixed with the sigil, and ! as the twigil for
1029 private attrs). This should not affect any code, unless
1030 you broke encapsulation, in which case, it is your problem
1033 !! Class::MOP::Class::Immutable has been removed
1035 * Class::MOP::Method::Constructor
1036 - this has been moved out of Class::MOP::Class::Immutable
1037 and is a proper subclass of Class::MOP::Method now.
1040 - this module now uses Class::MOP::Immutable for the
1041 immutable transformation instead of
1042 Class::MOP::Class::Immutable.
1044 + Class::MOP::Immutable
1045 - this module now controls the transformation from a mutable
1046 to an immutable version of the class. Docs for this will
1047 be coming eventually.
1050 0.36 Sun. Nov. 5, 2006
1052 - added a few 'no warnings' lines to keep annoying
1053 (and meaningless) warnings from chirping during
1057 - some more bootstrapping is now done on the new
1060 * Class::MOP::Class::Immutable
1062 - constructor generation is now handled by
1063 the Class::MOP::Method::Constructor class
1065 * Class::MOP::Method::Constructor
1066 - created this to handle constructor generation
1067 in Class::MOP::Class::Immutable
1069 * Class::MOP::Attribute
1071 - attributes now delegate to the
1072 Class::MOP::Method::Accessor to generate
1075 * Class::MOP::Method::Accessor
1076 - all accessor generation functions from
1077 Class::MOP::Attribute have been moved here

1093 - adjusted tests for this
1094 - added the Class::MOP::Instance attributes

1106 encapsulate most of the work into the
1107 &get_method_map method
1108 - made several adjustments for the change
1109 in Class::MOP::Method
1110 - &add_attribute now checks if you are adding
1111 a duplicate name, and properly removes the

1114 - adjusted docs for this
1116 * Class::MOP::Class::Immutable
1117 - added caching of &get_method_map

1123 &list_all_package_symbols
1125 0.34 Sat. Aug. 26, 2006
1127 - added the %:methods attribute, which like
1128 the $:version and such just actually goes
1129 to the symbol table to get it's stuff.
1130 However, it makes the MOP more complete.
1132 - The &create method now requires that all
1133 but the package name now is passed in as
1134 named parameters. See docs for more info.
1135 - updated docs and tests for this
1137 * Class::MOP::Object
1138 - added &dump method to easily Data::Dumper

1161 - added tests for this
1163 * Class::MOP::Package
1164 - fixed an issue with perl 5.8.1 and how it deals
1165 with symbol tables. The namespace hash is now
1166 always reloaded from the symbol table.
1168 ~ lots of misc. documentation cleanup
1170 0.32 Sat. Aug. 12, 2006
1171 + added Class::MOP::Object so that the
1172 metamodel is more complete (and closer
1173 to what Perl 6 will probably be).

1177 the primary gateway between the metaclass
1178 and the Perl 5 symbol table
1179 - added many tests for this
1180 - this class is now a subclass of
1182 - added some tests to reflect this

1186 use Class::MOP::Package methods instead
1188 * Class::MOP::Module
1189 - adding the $:version attribute in the bootstrap
1190 so that Module has a version as an attribute
1191 - see comment in Class::MOP for details
1192 - added the $:authority attribute to this module
1193 as well as an &identifier method, to bring us
1194 ever closer to Perl 6 goodness
1195 - I have added $AUTHORITY to all the modules
1196 - added tests for this

1212 anywhere within the class hierarchy
1214 * Class::MOP::Attribute
1215 - added &set_value and &get_value for getting
1216 the value of the attribute for a particular
1219 0.30 Wed. July 5, 2006
1220 ---------------------------------------
1221 This is the first version of Class::MOP
1222 to introduce the immutable features which
1223 will be used for optimizating the MOP.
1224 This support should still be considered
1225 experimental, but moving towards stability.
1226 ---------------------------------------
1228 * Created Class::MOP::Class::Immutable
1230 * Created the Class::MOP::Package and
1231 Class::MOP::Module classes to more
1232 closely conform to Perl 6's meta-model
1235 - now inherits from Class::MOP::Module
1236 - several methods moved to ::Module and
1237 ::Package and now inherited
1238 - added tests for this
1240 * Class::MOP::Instance
1241 - added an is_inlinable method to allow other
1242 classes to check before they attempt to optimize.
1243 - added an inline_create_instance to inline
1244 instance creation (of course)
1247 - the Class::MOP::Class::*_package_variable
1248 methods are all now methods of Class::MOP::Package
1249 and called *_package_symbol instead. This is
1250 because they are now more general purpose symbol
1251 table manipulation methods.
1253 0.29_02 Thurs. June 22, 2006
1254 ++ DEVELOPER RELEASE ++
1256 - small change in &create so that it behaves

1312 - attribute slot initialization is now the responsibility
1313 of the attribute itself, and construct_instance now
1314 delegates appropriately
1316 * Class::MOP::Attribute
1317 - attribute slot initialization is now the responsibility
1318 of the attribute itself, so we added a method for it
1319 called initialize_instance_slot

1348 0.21 Wed. March 15, 2006
1350 - fixed issue where metaclasses are reaped from

1376 - &add_after_method_modifier
1377 - &add_around_method_modifier
1378 - added tests and docs for these
1379 - added &find_next_method_by_name which finds the
1380 equivalent of SUPER::method_name

1383 - reduced the dependency on B, no need to always
1387 - added docs to the C3 method dispatch order test

1396 - changed how clone_instance behaves, it now only does a
1397 shallow clone (see docs for more details)
1398 - added docs and tests
1400 0.10 Tues Feb. 14, 2006
1401 ** This release was mostly about writing more tests and
1402 cleaning out old and dusty code, the MOP should now
1403 be considered "ready to use".
1405 - adding more tests to get coverage up a little higher,
1406 mostly testing errors and edge cases.
1407 - test coverage is now at 99%
1410 - no longer optionally exports to UNIVERSAL::meta or
1411 creates a custom metaclass generator, use the

1425 0.06 Thurs Feb. 9, 2006
1427 - adding new metaclass pragma to make setting up the
1428 metaclass a little more straightforward
1431 - clean up bootstrapping to include more complete
1432 attribute definitions for Class::MOP::Class and
1433 Class::MOP::Attribute (accessors, readers, writers,
1434 etc.) ... it is redundant, but is useful meta-info
1438 - fixing minor meta-circularity issue with &meta, it
1439 is now more useful for subclasses
1440 - added &get_attribute_map as an accessor for the
1441 hash of attribute meta objects
1442 - &compute_all_applicable_attributes now just returns
1443 the attribute meta-object, rather than the HASH ref
1444 since all the same info can be gotten from the
1445 attribute meta-object itself
1446 - updated docs & tests to reflect
1447 - added &clone_instance method which does a deep clone
1448 of the instance structure created by &construct_instance
