1 Revision history for Perl extension Class-MOP.
5 - add inline version of rebless_instance_structure. (doy)
6 - change inline_slot_access to use single quotes (gphat)
10 - Moved the __INSTANCE__ parameter to _construct_instance from
12 - Fixed some issues involving metaclasses of metaclasses and
15 0.87 Sun, Jun 21, 2009
17 - Made sure to always local-ize $@ and $SIG{__DIE__} before
18 calling an eval. Fixes RT #45973.
21 - Synced docs about immutability with the current reality (which
22 changed back in 0.82_01)
23 - Removed the immutable_transformer method, which had been
24 returning undef since 0.82_01 anyway.
27 - Got rid of tests which needed Moose and improved testing of
28 constructor/destructor inlining warnings. Fixes RT #47119.
30 0.86 Tue, Jun 16, 2009
32 - If you redefined a subroutine at runtime and then wrapped it
33 with a method modifier, the modifier could in some cases wrap
34 the original version of the subroutine. Fixes RT #46957.
37 - make_immutable issues a warning instead of overriding an
38 existing DESTROY method (Dylan William Hardison). Fixes RT
42 * Class::MOP::Attribute
43 - Allow default values to be Class::MOP::Methods. (Florian
45 - Test the above. (Rhesa Rozendaal)
46 - Tweak original commit so the intent matches the accepted
47 behavior (Nicholas Perez)
50 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
53 - Add direct_subclasses method (Sartak)
54 - Tests for subclasses and direct_subclasses (Sartak)
55 - subname is no longer used unconditionally in add_method, but
56 only if the code reference's name is '__ANON__' (nothingmuch)
57 - Add a hook for _superclasses_updated (Sartak)
60 - Remove long, old warning about possibly outdated modules
63 0.84 Tue, May 12, 2009
65 - Depend on Text::Exception 0.27 to avoid failing tests ond old
69 - Made is_class_loaded a little stricter. It was reporting that
70 a class was loaded if it merely had an @ISA variable in its
71 stash. Now it checks that the @ISA var has elements in it.
72 - Deprecate in_global_destruction and subname re-exporting
76 - Explicitly use Devel::GlobalDestruction and Sub::Name
80 - Disable prototype mismatch warnings for add_package_symbol.
83 0.83 Mon, April 27, 2009
85 - Fix segfault when calling get_method_map on a metaclass for an empty
88 0.82_02 Fri, April 24, 2009
89 * Class::MOP::Method::Inlined
90 - Don't inline if the expected method is not defined at all (happens with
91 e.g. Moose::Object::_new is the expected method due to an overridden
94 - Some tests were trying to load Class::MOP::Immutable, which
95 was removed in 0.82_01.
97 0.82_01 Thu, April 23, 2009
98 * Class::MOP::Immutable (and others)
99 - Refactor the immutability system to use a pre-defined class
100 for the immutable metaclass of Class::MOP::Class::Immutable::$class
101 - Rather than generating methods into this class every time, use
102 a Trait (basic mixin) to supply the cached methods
103 - Remove the hack that returns the mutable metaclass for
104 metacircularity in order to provide consistent meta-metaclasses
105 for the Moose compatibility handling code
106 (mst broke it, nothingmuch fixed it)
108 0.82 Mon, April 20, 2009
110 - The deprecation wrappers for some renamed methods were not
111 passing arguments to the new method. (nothingmuch)
113 * Class::MOP::Immutable
114 - Warn during immutablization if the local class provides its own
115 constructor, to parallel the warning in Moose when a superclass
116 provides its own constructor (doy)
118 0.81 Tue, April 7, 2009
121 * Class::MOP::Instance
122 * Class::MOP::Attribute
123 * Class::MOP::Method::Accessor
124 * Class::MOP::Method::Constructor
125 - Include stack traces in the deprecation warnings introduced in
126 0.80_01. (Florian Ragwitz)
129 - Avoid c compiler warnings by declaring some unused function
130 arguments. (Florian Ragwitz)
132 0.80_01 Sun, April 5, 2009
134 - Make sure to preserve any compiler flags already defined in
135 Config.pm. Patch by Vincent Pit. RT #44739.
137 * Many methods have been renamed with a leading underscore, and a
138 few have been deprecated entirely. The methods with a leading
139 underscore are consider "internals only". People writing
140 subclasses or extensions to Class::MOP should feel free to
141 override them, but they are not for "public" use.
144 - construct_class_instance => _construct_class_instance (use new_object)
145 - construct_instance => _construct_instance (use new_object)
146 - check_metaclass_compatibility => _check_metaclass_compatibility
147 - create_meta_instance => _create_meta_instance (use get_meta_instance)
148 - clone_instance => _clone_instance (use clone_object)
149 - compute_all_applicable_methods is deprecated, use get_all_methods
150 - compute_all_applicable_attributes is deprecated, use get_all_attributes
152 - Class::MOP::Instance
153 - bless_instance_structure is deprecated and will be removed
157 - create has been renamed to _instantiate_module. This method
158 does not construct an object, it evals some code that
159 creates the relevant package in Perl's symbol table.
161 - Class::MOP::Method::Accessor
162 - initialize_body => _initialize_body (this is always called
163 when an object is constructed)
164 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
166 - Class::MOP::Method::Constructor
167 - initialize_body => _initialize_body (this is always called
168 when an object is constructed)
169 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
170 - attributes => _attributes
171 - meta_instance => _meta_instance
173 0.80 Wed, April 1, 2009
175 - Call user_class->meta in fewer places, with the eventual goal
176 of allowing the user to rename or exclude ->meta
177 altogether. Instead uses Class::MOP::class_of. (Sartak)
180 - New class_of function that should be used to retrieve a
181 metaclass. This is unlike get_metaclass_by_name in that it
182 accepts instances, not just class names. (Sartak)
185 - load_first_existing_class didn't actually load the first
186 existing class; instead, it loaded the first existing and
187 compiling class. It now throws an error if a class exists (in
188 @INC) but fails to compile. (hdp)
192 - we had some semi-buggy code that purported to provide a
193 HAS_ISAREV based on whether mro had get_isarev (due to an
194 oversight, it always returned 1). Since mro and MRO::Compat
195 have always had get_isarev, HAS_ISAREV was pointless. This
196 insight simplified the subclasses method by deleting the
197 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
199 0.79 Fri, March 29, 2009
200 * No changes from 0.78_02.
202 0.78_02 Thu, March 26, 2009
204 * Class::MOP::Immutable
205 - A big backwards-incompatible refactoring of the Immutable API,
206 and the make_immutable/make_mutable pieces of the Class
207 API. The core __PACKAGE__->meta->make_immutable API remains
208 the same, however, so this should only affect the most
212 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
213 has been fixed to be backwards compatible with 5.8.x.
216 - Add a hook for rebless_instance_away (Sartak)
217 - Use blessed instead of ref to get an instance's class name
218 in rebless_instance. (Sartak)
220 0.78_01 Wed, March 18, 2009
222 - Revised and reorganized all of the API documentation. All
223 classes now have (more or less) complete API documentation.
226 * Class::MOP::Instance
227 - Reblessing into a package that supports overloading wasn't
228 properly adding overload magic to the object due to a bug
229 in (at least) 5.8.8. We now use $_[1] directly which seems
230 to set the magic properly. (Sartak)
232 * Class::MOP::Attribute
233 - The process_accessors method is now private. A public alias
234 exists (and will stick around for a few releases), but it
235 warns that calling the public method is deprecated.
237 * Class::MOP::Method::Generated
238 - Removed the new and _new methods, since this is an abstract
239 base class, and all existing subclasses implement their own
243 - Stop is_class_loaded from thinking a class is loaded if it
244 only has an empty GV (Florian Ragwitz).
245 - Add a test for this (Yappo).
246 - Refactor get_all_package_symbols to allow short-circuiting
248 - Use this in is_class_loaded (Florian Ragwitz).
249 - Stop segfaulting when trying to get the name from a sub that's
250 still being compiled (Florian Ragwitz).
251 - Add tests for this (Florian Ragwitz).
252 - Prefix all public symbols with "mop_" (Florian Ragwitz).
253 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
254 - Simplify creating simple xs reader methods (Florian Ragwitz).
255 - Make everything compile with c++ compilers (Florian Ragwitz).
256 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
259 - Remove optional test plans for tests depending on Sub::Name as
260 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
263 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
265 0.78 Mon, February 23, 2009
266 * No changes from 0.77_01
268 0.77_01 Sun, February 22, 2009
270 - This package now requires its XS components. Not using
271 Sub::Name lead to different behavior and bugginess in the pure
272 Perl version of the code. A Moose test would fail when run
273 against the pure Perl version of this code.
275 * Class::MOP::Instance
276 - The inline_* methods now quote attribute names themselves, and
277 don't expect to receive a quoted value.
280 0.77 Sat, February 14, 2009
282 - Avoid assertion errors on debugging perls in is_class_loaded
286 - Fixed various corner cases where is_class_loaded incorrectly
287 returned true for a class that wasn't really loaded. (Dave
291 - Add get_all_method_names (Sartak)
292 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
294 * Class::MOP::Package
295 - Disable deprecated get_all_package_symbols in list
296 context. (Florian Ragwitz)
299 - Make sure we generate a BSD-compatible Makefile (Florian
303 - The misspelled "check_metaclass_compatability" method we've
304 kept around for backwards compat_i_bility will be removed in a
305 near future release. You've been warned.
307 0.76 Thu, January 22, 2009
308 * Class::MOP::Method::Generated
309 - Added new private methods to support code generation, which
310 are being used by Moose and can be used by MooseX
312 - Generated methods are now generated with a #line directive
313 reflecting the source of the generated method. (nothingmuch)
316 - Clarified documentation of methods that return
317 Class::MOP::Method objects. (doy)
320 - Clarified documentation of the metaclass cache methods. (Sartak)
323 - Add test showing how the xs Class::MOP::is_class_loaded can
324 be made to operate differently to the pure perl version (t0m)
326 0.75 Wed, December 31, 2008
328 - A class that was made immutable and then mutable could end up
329 sharing an immutable transformer object
330 (Class::MOP::Immutable) with other classes, leading to all
331 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
333 0.74 Tue, December 25, 2008
335 - Add an xs implementation of Class::MOP::is_class_loaded (closes
336 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
337 - Changed internals to make prehashing of hash keys easier and less
338 error-prone. (Florian Ragwitz)
340 - Fix documentation to show that around modifiers happen on both
341 sides of the modified method. (Dave Rolsky)
343 0.73 Tue, December 16, 2008
345 - Don't use Perl_mro_meta_init. It's not part of the public perl
346 api. Fixes failures to build on Win32 (RT #41750). (Florian
348 * t/082_get_code_info.t
349 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
350 munger anonymous subs when under -d and so making the tests
351 succeed in that case.
353 0.72 Mon, December 8, 2008
354 * Class::MOP::Package
355 - Pass options to _new, so subclass' attributes can be
358 - In the docs, indicate that package_name and name are required
359 when calling ->wrap (Stefan O'Rear)
361 0.71_02 Fri, December 5, 2008
362 * Class::MOP::Immutable
363 - Added a new attribute, inlined_constructor, which is true if
364 the constructor was inlined.
365 * Class::MOP::Package
366 - Make get_all_package_symbols return a hash ref in scalar
367 context and deprecate calling it in list context with a
368 warning. (Florian Ragwitz)
370 - Various improvements and refactoring, making things more robust and
371 easier to maintain. (Florian Ragwitz)
373 0.71_01 Wed, December 3, 2008
375 - Add an "execute" method to invoke the body so
376 we can avoid using the coderef overload (Sartak)
377 * Class::MOP::Immutable
378 - When we memoize methods, get their results lazily
379 to remove some compile-time cost (Sartak)
380 - Small speedup from eliminating several method
383 - Some small internal tweaks to try to reduce the number of
384 times we call get_method_map when bootstrapping the MOP. This
385 might make loading Class::MOP (and Moose) a little
386 faster. (Dave Rolsky)
387 - Implemented an optional XS version of get_method_map. Mostly
388 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
389 help form Florian Ragwitz. (Dave Rolsky)
390 - Make the behaviour of of get_all_package_symbols (and
391 therefore get_method_map) consistent for stub methods. Report
392 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
394 0.71 Wed November 26, 2008
397 - Actual package creation has moved upward from
398 Class to Module so that Moose roles can share
401 0.70_01 Mon, November 19, 2008
403 - Fixes for failures with blead (Florian Ragwitz)
404 - Silenced compiler warnings (Florian Ragwitz)
406 0.70 Fri, November 14, 2008
408 - Fixed an odd corner case where the XS version of
409 get_all_package_symbols could cause a segfault. This only
410 happened with inlined constants in Perl 5.10.0 (Florian
413 0.69 Fri, November 7, 2008
414 * Class::MOP::Method::Wrapped
415 - Added introspection methods for method modifiers (Dave Rolsky)
418 0.68 Fri October 24, 2008
420 - Make load_class require by file name instead of module name.
421 This stops confusing error messages when loading '__PACKAGE__'.
423 - Add load_one_class_of function to enable you to load one of a
424 list of classes, rather than having to call load_class multiple
425 times in an eval. (t0m)
427 0.67 Tue October 14, 2008
429 - Call a method on the class after setting the superclass list
430 so that we can get Perl to detect cycles before MRO::Compat
431 spirals into an infinite loop (sartak)
432 - Reported by Schwern, [rt.cpan.org #39001]
433 - In create(), pass unused options on to initialize()
434 - added test for this
436 0.66 Sat September 20, 2008
437 !! This release has an incompatible change regarding !!
438 introspection of a class's method with Class::MOP::Class !!
441 - We (us maintainers) now run all tests with XS and then without
442 XS, which should help us catch skew between the XS/pure Perl
446 ! The alias_method method has been deprecated. It now simply
447 calls add_method instead. There is no distinction between
448 aliased methods and "real" methods.
450 This means that methods added via alias_method now show up as
451 part of the class's method list/map. This is a backwards
452 incompatible change, but seems unlikely to break any
453 code. Famous last words. (Dave Rolsky)
456 - Fixed the spelling of "compatibility", but we still have a
457 "check_metaclass_compatability" method for backwards
460 0.65 Mon September 1, 2008
461 For those not following the series of dev releases, the changes
462 from 0.64 from 0.65 can mostly be summed up as a lot performance
463 improvements by nothingmuch, including new optional XS versions of
464 some methods. Also, Class::MOP now works _without_ any XS modules,
465 for sad systems without a compiler.
468 - Added name and package_name XS accessors, and make sure all
469 the XS and Perl versions work the same way. (Dave Rolsky)
472 - The XS versions of various methods just returned undef when
473 called class methods, rather than dying like the pure Perl
474 versions. (Dave Rolsky)
476 0.64_07 Fri August 29, 2008
478 - Silenced warnings that managed to break Moose tests when XS
479 was loaded. (Dave Rolsky)
480 - Some XS versions of methods were ignored because of typos in
481 MOP.xs. (Dave Rolsky)
483 0.64_06 Mon August 25, 2008
484 * Class::MOP (MOP.xs)
485 - Another MS VC++ fix, cannot declare a variable in the middle
486 of a scope (Taro Nishino).
488 0.64_05 Sun August 24, 2008
490 - None of the dev releases actually loaded the XS properly, but
491 we silently fell back to the pure Perl version of the
494 * Class::MOP (MOP.xs)
495 - Replaced some code that used functions not available on Visual
496 C++ with some Perl XS API bits (Dave Rolsky).
498 0.64_04 Sat August 23, 2008
500 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
502 * pod.t and pod_coveraget.t
503 - These are no longer shipped with the tarball because of bogus
504 failures from CPAN testers. (Dave Rolsky)
506 0.64_03 Thu August 21, 2008
507 * Class::MOP::Package
508 - Some (legit) code was misparsed by earlier 5.8.x
509 releases. (nothingmuch)
512 - Fix a constant in void context warning (nothingmuch)
514 0.64_02 Thu August 21, 2008
515 * Makefile.PL and Class::MOP
516 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
519 - Add missing prereqs that got lost in the switch away from
522 * Class::MOP::Instance
523 - New method - get_all_attributes (nothingmuch)
525 0.64_01 Wed August 20, 2008
527 - We now check to see if you have a compiler. If you don't, the
528 module installs without some XS bits, but will work the same
529 as with XS. This should make it easier to install on platforms
530 without a compiler (like Windows). (Dave Rolsky)
533 - Perl 6 style attribute naming replaced with sane style ('methods', not
534 '%!methods'). These changes should not impact any existing API uses.
538 - Quite a number of optimizations based on profiling, including
539 allowing constructors to take hash references instead of
540 hashes, duplicating some frequently used code in XS, and
541 making constructors immutable. These changes should not impact
542 any existing API uses. (nothingmuch)
545 - Constructors now respect the meta attributes of their subclasses,
546 facilitating MOP extensibility. More related changes will happen in the
547 next several releases. (nothingmuch)
550 - New method - get_all_methods, replaces the deprecated
551 compute_all_applicable_methods. get_all_attributes provided for
552 consistency (nothingmuch)
553 - New method - wrap_method was refactored out of get_method_map
555 - New API for meta instance invalidation - invalidate_meta_instance,
556 invalidate_meta_instances, add_dependent_meta_instance,
557 remove_dependent_meta_instance, called automatically when attribute
558 definitions change and allows notification of dependent subclasses.
561 0.64 Sun August 3, 2008
562 * Class::MOP::Immutable
563 - fixing subtle edge case in immutable when you
565 - clean up option processing (nothingmuch)
567 * Class::MOP::Instance
568 - inlined initialize slot didn't match
569 non-inlined (nothingmuch)
571 0.63 Mon July 7, 2008
573 - load_class will initialize a metaclass even if
574 the class is already loaded (sartak)
575 - load_class now returns the metaclass instance
576 instead of just 1 (sartak)
579 - better error messages (sartak and Dave Rolsky)
581 0.62 Wed June 18, 2008
582 - in is_class_loaded, recognize scalar references (as opposed to globs) in
583 the symbol table as methods (these are optimized constant subs)
585 0.61 Fri. June 13, 2008
586 - Okay, lets give this another try and see if PAUSE
587 recognizes it correct this time.
589 0.60 Thurs. Jun 12, 2008
590 - Fixed a version number issue by bumping all modules
593 0.59 Thurs. Jun 12, 2008
594 !! Several fixes resulting in yet another 25-30% speedup !!
597 - now stores the instance of the instance
598 metaclass to avoid needless recomputation
599 and deletes it when the cache is blown
600 - introduce methods to query Class::MOP::Class for
601 the options used to make it immutable as well as
602 the proper immutable transformer. (groditi)
604 * Class::MOP::Package
605 - {add, has, get, remove}_package_symbol all
606 now accept a HASH ref argument as well as the
607 string. All internal usages now use the HASH
611 - MOP.xs does sanity checks on the coderef
613 - is_class_loaded check now uses code that
614 was improved in Moose's ClassName type
616 - nonsensical (undef, empty, reference) class
617 names now throw a more direct error in
619 - tests for this and other aspects of
625 Class::MOP::Method::Wrapped
626 Class::MOP::Attribute
627 - switched usage of reftype to ref because
630 0.58 Thurs. May 29, 2008
631 (late night release engineering)--
633 - fixing the version is META.yml, no functional
634 changes in this release
636 0.57 Wed. May 28, 2008
637 !! Several speedups resulting in 20-25% speedups !!
638 || (thanks to konobi, groditi, mst & CataMoose) !!
641 - made get_method_map use list_all_package_symbols
642 instead of manually grabbing each symbol
643 - streamlining &initialize somewhat, since it gets
646 * Class::MOP::Package
647 - made {get, has}_package_symbol not call
649 - inlining a few calls to &name with
650 direct HASH access key access
651 - added get_all_package_symbols to fetch
652 a HASH of items based on a type filter
653 similar to list_all_package_symbols
654 - added tests for this
657 Class::MOP::Method::Constructor
658 Class::MOP::Method::Generated
659 Class::MOP::Method::Accessor
660 - added more descriptive error message to help
661 keep people from wasting time tracking an error
662 that is easily fixed by upgrading.
664 * Class::MOP::Immutable
665 - Don't inline a destructor unless the user actually
667 - added tests for this
669 0.56 Saturday, May 24, 2008
671 - we now get the &check_package_cache_flag
672 function from MRO::Compat
673 - All XS based functionality now has a
674 Pure Perl alternative
675 - the CLASS_MOP_NO_XS environment variable
676 can now be used to force non-XS versions
679 * Class::MOP::Attribute
680 - add has_read_method and has_write_method
681 - get_{read,write}_method_ref now wraps the
682 anon-sub ref in the method metaclass when
684 - added tests for this
686 * Class::MOP::Immutable
687 - added the ability to "wrap" methods when
688 making the class immutable
691 - now handling the edge case of ->meta->identifier
692 dying by wrapping add_package_symbol to specifically
693 allow for it to work.
694 - added tests for this
696 * Class::MOP::Attribute
698 Class::MOP::Immutable
699 - any time a method meta object is constructed
700 we make sure to pass the correct package and
701 method name information
704 Class::MOP::Method::Wrapped
705 Class::MOP::Method::Generated
706 Class::MOP::Method::Accessor
707 Class::MOP::Method::Consructor
708 - the &wrap constructor method now requires that a
709 'package_name' and 'name' attribute are passed. This
710 is to help support the no-XS version, and will
711 throw an error if these are not supplied.
712 - all these classes are now bootstrapped properly
713 and now store the package_name and name attributes
716 ~ Build.PL has been removed since the
717 Module::Install support has been removed
719 0.55 Mon. April 28, 2008
720 - All classes now have proper C3 MRO support
721 - added MRO::Compat as a dependency to allow
722 for the C3 MRO support to Just Work in all
726 - rebless_instance now returns the instance
727 it has just blessed, this is mostly to
729 - set the attr correctly in rebless_instance
730 when it has no init_arg
731 - tweaked &linear_isa and &class_precedence_list
732 to support c3 classes.
734 0.54 Fri. March, 14, 2008
737 - making sure that load_class never gets
738 passed a value from @_ or $_ to squash
739 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
742 - make_{immutable,mutable} now return 1
744 - improved error handling in ->create method
745 - rebless_instance now takes extra params which
746 will be used to populate values
747 - added tests for this
750 - localizing the Data::Dumper configurations so
751 that it does not pollute others (RT #33509)
757 Class::MOP::Attribute
758 - these classes no longer define their own ->meta,
759 but instead just inherit from Class::MOP::Object
761 * Class::MOP::Instance
762 Class::MOP::Immutable
763 - these classes now inherit from Class::MOP::Object
766 - fixed the filename length on several
767 test files so we install on VMS better
769 - fixed incorrect use of catdir when it
770 should be catfile (RT #32385)
772 0.53 Thurs. Feb. 14, 1008
773 ~~ several doc. fixes and updates ~~
776 Class::MOP::Method::Constructor
777 Class::MOP::Attribute
778 - making init_arg accept an undefined value
779 to indicate that no constructor args can
780 be passed (thanks to nothingmuch)
781 - added tests for this
782 - added attribute initializer attribute (rjbs)
785 - making this use the new init_arg => undef
786 feature instead of the silly hack from
787 before (thanks to nothingmuch)
789 0.52 Tues. Jan. 22, 2008
791 - fixed bug in rebless_instance
794 * Class::MOP::Method::Constructor
795 - removed assumptions about the existence of
798 0.51 Mon. Jan. 14, 2008
799 ~~~ some misc. doc. fixes ~~~
800 ~~ updated copyright dates ~~
803 - now sets the IS_RUNNING_ON_5_10
804 constant so that we can take advantage
805 of some of the nice bits of 5.10
808 - uses the IS_RUNNING_ON_5_10 flag to
809 optimize the &linearized_isa method
810 and avoid the hack/check for circular
811 inheritence in &class_precedence_list
812 - added rebless_instance method (Sartak)
813 - added tests for this
815 * Class::MOP::Immutable
816 - the immutable class now keeps track of
817 the transformer which immutablized it

830 * Class::MOP::Immutable
831 - fixed a bug (see above)
833 * Class::MOP::Attribute
836 0.49 Fri. Dec. 14, 2007
837 !! Class::MOP now loads 2 x faster !!
838 !! with XS speedups (thanks konobi) !!
841 - removed the dependency on B
842 - added two XS functions (thanks konobi)
843 - get_code_info($code) which replaces all
844 the B fiddling we were doing with
845 faster/leaner XS level fiddling
846 - check_package_cache_flag($pkg_name) which
847 returns the PL_sub_generation variable to
848 be used to help manage method caching.
851 In 5.10 or greater this will actually
852 use the mro::get_pkg_gen instead to give
853 even more accurate caching information.
854 blblack++ for that stuff :)
857 - added the &subclasses method (thanks rlb)
858 - added the update_package_cache_flag and
859 reset_package_cache_flag which help keep
860 track of when we need to re-fetch the
862 - Several small improvements to take advantage
863 of the new method map caching features
865 0.48 Mon. Nov. 26, 2007
866 * Class::MOP::Attribute
867 - fixed get_read/write_method to handle the
868 HASH ref case, which makes the

872 0.47 Sat. Nov. 24, 2007
873 * Class::MOP::Attribute
874 - fixed misspelling in get_write_method_ref
875 - added more tests for this
877 0.46 Fri. Nov. 23, 2007
879 - added the linearized_isa method instead of constantly
880 pruning duplicate classes (this will be even more
881 useful in the 5.10-compat version coming soon)
883 * Class::MOP::Attribute
884 - added the get_read_method_ref and get_write_method_ref
885 methods which allow you to retrieve a CODE ref which
886 can always be used to read or write an attribute.
888 0.45 Thurs. Nov. 13, 2007
889 * Class::MOP::Attribute
890 - Fix error message on confess (groditi)
892 0.44 Thurs. Nov. 13, 2007
893 - Apparently I didn't make dist correctly (groditi)
895 0.43 Thurs. Nov. 13, 2007
897 - Add support for the 'builder' attribute (groditi)
900 - optimise metaclass-already-exists check in
901 construct_class_instance (groditi)
902 - duplicate check into initialize to save a
903 call through (groditi)
905 * Class::MOP::Attribute
906 - Add support for the 'builder' attribute (groditi)
907 - Make predicates check for the existence of a value, not whether
908 it is defined (groditi)
910 * Class::MOP::Instance
911 - Make predicates check for the existence of a value, not whether
912 it is defined (groditi)
914 * Class::MOP::Method::Accessor
915 - made this a subclass of Class::MOP::Method::Generated
916 - removed the relevant attributes
918 * Class::MOP::Method::Constructor
919 - fixed the cached values we had to be more sane
920 - made this a subclass of Class::MOP::Method::Generated
921 - fixed generated constructor so it properly handles
923 - added tests for this
924 - added the option to allow for both inlined and
925 non-inlined constructors.
926 - Update inlined methods for builder and predicate changes (groditi)
928 * Class::MOP::Method::Generated
929 - added this class as an abstract base for the
930 Class::MOP::Method::{Constructor,Accessor} classes
931 - added tests for this
934 - Alter tests (005, 014 020, 021) for new builder addition (groditi)
935 - Tests for new predicate behavior (and corrections to old tests) (groditi)
938 - Update ArrayRef based class example to work with predicate changes
940 0.42 Mon. July 16, 2007
941 !!! Horray for mst, he fixed it !!!
943 * Class::MOP::Package
944 - alter symbol table handling to deal with 5.8.x and 5.9.x
947 - Get rid of the crappy workaround from 0.40/41
949 0.41 Sun. July 15, 2007
951 Arghh!!! My TODO test didn't work, so I handle
952 it manually now so that people can use this
953 with 5.9.5/bleadperl without issue.
955 0.40 Tues, July 3, 2007
957 ~ marked a test in 003_methods.t as TODO
958 for perl 5.9.5 (this test is irrelvant to
959 the module functioning on 5.9.5 for the most
962 0.39 Mon. June 18, 2007
963 * Class::MOP::Immutable
964 - added make_metaclass_mutable + docs (groditi)
965 - removed unused variable
966 - added create_immutable_transformer
967 necessary for sane overloading of immutable behavior
968 - tests for this (groditi)
971 - Immutability can now be undone,
972 added make_mutable + tests + docs (groditi)
973 - Massive changes to the way Immutable is done
974 for details see comments next to make_immutable
975 This fixes a bug where custom metaclasses broke
976 when made immutable. We are now keeping one immutable
977 metaclass instance per metaclass instead of just one
978 to prevent isa hierarchy corruption. Memory use will go
979 up, but I suspect it will be neglible.
980 - New tests added for this behavior. (groditi)
982 0.38 Thurs. May 31, 2007
983 ~~ More documentation updates ~~
985 * Class::MOP::Package
986 - we now deal with stub methods properly

988 - fixed some tests failing on 5.9.5 (thanks blblack)
990 * Class::MOP::Attribute
991 - added get_read_method and get_write_method
992 thanks to groditi for this code, tests
994 - added tests and POD for this
997 - fixed RT issue #27329, clone object now
998 handles undef values correctly.
999 - added tests for this
1000 - Corrected anon-class handling so that they
1001 will not get reaped when instances still
1002 exist which need to reference them. This is
1003 the correct behavior, hopefully this is an
1004 obscure enough feature that there are not too
1005 many work arounds out in the wild.
1006 - added tests for this by groditi
1007 - updated docs to explain this
1010 - load custom metaclasses automatically (thanks groditi)
1011 - added tests for this behavior
1013 0.37 Sat. March 10, 2007

1020 * Class::MOP::Attribute
1021 - default now checks the instance with defined to
1022 avoid setting off bool-overloads (found by Carl Franks)
1026 - bad name in a test, causing meaningless failuress.
1031 ~~ GLOBAL CHANGES ~~
1032 - All attribute names are now consistent and follow Perl 6
1033 style (prefixed with the sigil, and ! as the twigil for
1034 private attrs). This should not affect any code, unless
1035 you broke encapsulation, in which case, it is your problem
1038 !! Class::MOP::Class::Immutable has been removed
1040 * Class::MOP::Method::Constructor
1041 - this has been moved out of Class::MOP::Class::Immutable
1042 and is a proper subclass of Class::MOP::Method now.
1045 - this module now uses Class::MOP::Immutable for the
1046 immutable transformation instead of
1047 Class::MOP::Class::Immutable.
1049 + Class::MOP::Immutable
1050 - this module now controls the transformation from a mutable
1051 to an immutable version of the class. Docs for this will
1052 be coming eventually.
1055 0.36 Sun. Nov. 5, 2006
1057 - added a few 'no warnings' lines to keep annoying
1058 (and meaningless) warnings from chirping during
1062 - some more bootstrapping is now done on the new
1065 * Class::MOP::Class::Immutable
1067 - constructor generation is now handled by
1068 the Class::MOP::Method::Constructor class
1070 * Class::MOP::Method::Constructor
1071 - created this to handle constructor generation
1072 in Class::MOP::Class::Immutable
1074 * Class::MOP::Attribute
1076 - attributes now delegate to the
1077 Class::MOP::Method::Accessor to generate
1080 * Class::MOP::Method::Accessor
1081 - all accessor generation functions from
1082 Class::MOP::Attribute have been moved here
1084 0.35 Sat. Sept. 30, 2006

1088 on this to come. Comments and patches are
1092 - All Class::MOP::* accessors are no longer
1093 re-generated in the bootstrap, instead
1094 they are aliased from the originals
1095 - fixed tests to reflect
1096 - added Class::MOP::Method (and its subclasses)
1098 - adjusted tests for this
1099 - added the Class::MOP::Instance attributes

1110 - changed how methods are dealt with to
1111 encapsulate most of the work into the
1112 &get_method_map method
1113 - made several adjustments for the change
1114 in Class::MOP::Method
1115 - &add_attribute now checks if you are adding
1116 a duplicate name, and properly removes the
1117 old one before installing the new one

1119 - adjusted docs for this
1121 * Class::MOP::Class::Immutable
1122 - added caching of &get_method_map

1128 &list_all_package_symbols
1130 0.34 Sat. Aug. 26, 2006
1132 - added the %:methods attribute, which like
1133 the $:version and such just actually goes
1134 to the symbol table to get it's stuff.
1135 However, it makes the MOP more complete.
1137 - The &create method now requires that all
1138 but the package name now is passed in as
1139 named parameters. See docs for more info.
1140 - updated docs and tests for this
1142 * Class::MOP::Object
1143 - added &dump method to easily Data::Dumper
1147 - cleaned up the initialization of attributes

1166 - added tests for this
1168 * Class::MOP::Package
1169 - fixed an issue with perl 5.8.1 and how it deals
1170 with symbol tables. The namespace hash is now
1171 always reloaded from the symbol table.
1173 ~ lots of misc. documentation cleanup
1175 0.32 Sat. Aug. 12, 2006
1176 + added Class::MOP::Object so that the
1177 metamodel is more complete (and closer
1178 to what Perl 6 will probably be).
1180 * Class::MOP::Package
1181 - refactored entire class, this is now
1182 the primary gateway between the metaclass
1183 and the Perl 5 symbol table
1184 - added many tests for this
1185 - this class is now a subclass of
1187 - added some tests to reflect this
1190 - refactored all symbol table access to
1191 use Class::MOP::Package methods instead
1193 * Class::MOP::Module
1194 - adding the $:version attribute in the bootstrap
1195 so that Module has a version as an attribute
1196 - see comment in Class::MOP for details
1197 - added the $:authority attribute to this module
1198 as well as an &identifier method, to bring us
1199 ever closer to Perl 6 goodness
1200 - I have added $AUTHORITY to all the modules
1201 - added tests for this

1217 anywhere within the class hierarchy
1219 * Class::MOP::Attribute
1220 - added &set_value and &get_value for getting
1221 the value of the attribute for a particular
1224 0.30 Wed. July 5, 2006
1225 ---------------------------------------
1226 This is the first version of Class::MOP
1227 to introduce the immutable features which
1228 will be used for optimizating the MOP.
1229 This support should still be considered
1230 experimental, but moving towards stability.
1231 ---------------------------------------
1233 * Created Class::MOP::Class::Immutable
1235 * Created the Class::MOP::Package and
1236 Class::MOP::Module classes to more
1237 closely conform to Perl 6's meta-model
1240 - now inherits from Class::MOP::Module
1241 - several methods moved to ::Module and
1242 ::Package and now inherited
1243 - added tests for this
1245 * Class::MOP::Instance
1246 - added an is_inlinable method to allow other
1247 classes to check before they attempt to optimize.
1248 - added an inline_create_instance to inline
1249 instance creation (of course)
1252 - the Class::MOP::Class::*_package_variable
1253 methods are all now methods of Class::MOP::Package
1254 and called *_package_symbol instead. This is
1255 because they are now more general purpose symbol
1256 table manipulation methods.
1258 0.29_02 Thurs. June 22, 2006
1259 ++ DEVELOPER RELEASE ++
1261 - small change in &create so that it behaves

1265 0.29_01 Fri. May 12, 2006
1266 ++ DEVELOPER RELEASE ++
1267 - This release works in combination with
1268 Moose 0.09_01, it is a developer release

1317 - attribute slot initialization is now the responsibility
1318 of the attribute itself, and construct_instance now
1319 delegates appropriately
1321 * Class::MOP::Attribute
1322 - attribute slot initialization is now the responsibility
1323 of the attribute itself, so we added a method for it
1324 called initialize_instance_slot

1353 0.21 Wed. March 15, 2006
1355 - fixed issue where metaclasses are reaped from

1381 - &add_after_method_modifier
1382 - &add_around_method_modifier
1383 - added tests and docs for these
1384 - added &find_next_method_by_name which finds the
1385 equivalent of SUPER::method_name
1387 0.12 Thurs. Feb 23, 2006
1388 - reduced the dependency on B, no need to always
1392 - added docs to the C3 method dispatch order test

1401 - changed how clone_instance behaves, it now only does a
1402 shallow clone (see docs for more details)
1403 - added docs and tests
1405 0.10 Tues Feb. 14, 2006
1406 ** This release was mostly about writing more tests and
1407 cleaning out old and dusty code, the MOP should now
1408 be considered "ready to use".
1410 - adding more tests to get coverage up a little higher,
1411 mostly testing errors and edge cases.
1412 - test coverage is now at 99%
1415 - no longer optionally exports to UNIVERSAL::meta or
1416 creates a custom metaclass generator, use the

1430 0.06 Thurs Feb. 9, 2006
1432 - adding new metaclass pragma to make setting up the
1433 metaclass a little more straightforward
1436 - clean up bootstrapping to include more complete
1437 attribute definitions for Class::MOP::Class and
1438 Class::MOP::Attribute (accessors, readers, writers,
1439 etc.) ... it is redundant, but is useful meta-info
1443 - fixing minor meta-circularity issue with &meta, it
1444 is now more useful for subclasses
1445 - added &get_attribute_map as an accessor for the
1446 hash of attribute meta objects
1447 - &compute_all_applicable_attributes now just returns
1448 the attribute meta-object, rather than the HASH ref
1449 since all the same info can be gotten from the
1450 attribute meta-object itself
1451 - updated docs & tests to reflect
1452 - added &clone_instance method which does a deep clone
1453 of the instance structure created by &construct_instance
