1 Revision history for Perl extension Class-MOP.
5 - add inline version of rebless_instance_structure. (doy)
9 - Moved the __INSTANCE__ parameter to _construct_instance from
11 - Fixed some issues involving metaclasses of metaclasses and
14 0.87 Sun, Jun 21, 2009
16 - Made sure to always local-ize $@ and $SIG{__DIE__} before
17 calling an eval. Fixes RT #45973.
20 - Synced docs about immutability with the current reality (which
21 changed back in 0.82_01)
22 - Removed the immutable_transformer method, which had been
23 returning undef since 0.82_01 anyway.
26 - Got rid of tests which needed Moose and improved testing of
27 constructor/destructor inlining warnings. Fixes RT #47119.
29 0.86 Tue, Jun 16, 2009
31 - If you redefined a subroutine at runtime and then wrapped it
32 with a method modifier, the modifier could in some cases wrap
33 the original version of the subroutine. Fixes RT #46957.
36 - make_immutable issues a warning instead of overriding an
37 existing DESTROY method (Dylan William Hardison). Fixes RT
41 * Class::MOP::Attribute
42 - Allow default values to be Class::MOP::Methods. (Florian
44 - Test the above. (Rhesa Rozendaal)
45 - Tweak original commit so the intent matches the accepted
46 behavior (Nicholas Perez)
49 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
52 - Add direct_subclasses method (Sartak)
53 - Tests for subclasses and direct_subclasses (Sartak)
54 - subname is no longer used unconditionally in add_method, but
55 only if the code reference's name is '__ANON__' (nothingmuch)
56 - Add a hook for _superclasses_updated (Sartak)
59 - Remove long, old warning about possibly outdated modules
62 0.84 Tue, May 12, 2009
64 - Depend on Text::Exception 0.27 to avoid failing tests ond old
68 - Made is_class_loaded a little stricter. It was reporting that
69 a class was loaded if it merely had an @ISA variable in its
70 stash. Now it checks that the @ISA var has elements in it.
71 - Deprecate in_global_destruction and subname re-exporting
75 - Explicitly use Devel::GlobalDestruction and Sub::Name
79 - Disable prototype mismatch warnings for add_package_symbol.
82 0.83 Mon, April 27, 2009
84 - Fix segfault when calling get_method_map on a metaclass for an empty
87 0.82_02 Fri, April 24, 2009
88 * Class::MOP::Method::Inlined
89 - Don't inline if the expected method is not defined at all (happens with
90 e.g. Moose::Object::_new is the expected method due to an overridden
93 - Some tests were trying to load Class::MOP::Immutable, which
94 was removed in 0.82_01.
96 0.82_01 Thu, April 23, 2009
97 * Class::MOP::Immutable (and others)
98 - Refactor the immutability system to use a pre-defined class
99 for the immutable metaclass of Class::MOP::Class::Immutable::$class
100 - Rather than generating methods into this class every time, use
101 a Trait (basic mixin) to supply the cached methods
102 - Remove the hack that returns the mutable metaclass for
103 metacircularity in order to provide consistent meta-metaclasses
104 for the Moose compatibility handling code
105 (mst broke it, nothingmuch fixed it)
107 0.82 Mon, April 20, 2009
109 - The deprecation wrappers for some renamed methods were not
110 passing arguments to the new method. (nothingmuch)
112 * Class::MOP::Immutable
113 - Warn during immutablization if the local class provides its own
114 constructor, to parallel the warning in Moose when a superclass
115 provides its own constructor (doy)
117 0.81 Tue, April 7, 2009
120 * Class::MOP::Instance
121 * Class::MOP::Attribute
122 * Class::MOP::Method::Accessor
123 * Class::MOP::Method::Constructor
124 - Include stack traces in the deprecation warnings introduced in
125 0.80_01. (Florian Ragwitz)
128 - Avoid c compiler warnings by declaring some unused function
129 arguments. (Florian Ragwitz)
131 0.80_01 Sun, April 5, 2009
133 - Make sure to preserve any compiler flags already defined in
134 Config.pm. Patch by Vincent Pit. RT #44739.
136 * Many methods have been renamed with a leading underscore, and a
137 few have been deprecated entirely. The methods with a leading
138 underscore are consider "internals only". People writing
139 subclasses or extensions to Class::MOP should feel free to
140 override them, but they are not for "public" use.
143 - construct_class_instance => _construct_class_instance (use new_object)
144 - construct_instance => _construct_instance (use new_object)
145 - check_metaclass_compatibility => _check_metaclass_compatibility
146 - create_meta_instance => _create_meta_instance (use get_meta_instance)
147 - clone_instance => _clone_instance (use clone_object)
148 - compute_all_applicable_methods is deprecated, use get_all_methods
149 - compute_all_applicable_attributes is deprecated, use get_all_attributes
151 - Class::MOP::Instance
152 - bless_instance_structure is deprecated and will be removed
156 - create has been renamed to _instantiate_module. This method
157 does not construct an object, it evals some code that
158 creates the relevant package in Perl's symbol table.
160 - Class::MOP::Method::Accessor
161 - initialize_body => _initialize_body (this is always called
162 when an object is constructed)
163 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
165 - Class::MOP::Method::Constructor
166 - initialize_body => _initialize_body (this is always called
167 when an object is constructed)
168 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
169 - attributes => _attributes
170 - meta_instance => _meta_instance
172 0.80 Wed, April 1, 2009
174 - Call user_class->meta in fewer places, with the eventual goal
175 of allowing the user to rename or exclude ->meta
176 altogether. Instead uses Class::MOP::class_of. (Sartak)
179 - New class_of function that should be used to retrieve a
180 metaclass. This is unlike get_metaclass_by_name in that it
181 accepts instances, not just class names. (Sartak)
184 - load_first_existing_class didn't actually load the first
185 existing class; instead, it loaded the first existing and
186 compiling class. It now throws an error if a class exists (in
187 @INC) but fails to compile. (hdp)
191 - we had some semi-buggy code that purported to provide a
192 HAS_ISAREV based on whether mro had get_isarev (due to an
193 oversight, it always returned 1). Since mro and MRO::Compat
194 have always had get_isarev, HAS_ISAREV was pointless. This
195 insight simplified the subclasses method by deleting the
196 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
198 0.79 Fri, March 29, 2009
199 * No changes from 0.78_02.
201 0.78_02 Thu, March 26, 2009
203 * Class::MOP::Immutable
204 - A big backwards-incompatible refactoring of the Immutable API,
205 and the make_immutable/make_mutable pieces of the Class
206 API. The core __PACKAGE__->meta->make_immutable API remains
207 the same, however, so this should only affect the most
211 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
212 has been fixed to be backwards compatible with 5.8.x.
215 - Add a hook for rebless_instance_away (Sartak)
216 - Use blessed instead of ref to get an instance's class name
217 in rebless_instance. (Sartak)
219 0.78_01 Wed, March 18, 2009
221 - Revised and reorganized all of the API documentation. All
222 classes now have (more or less) complete API documentation.
225 * Class::MOP::Instance
226 - Reblessing into a package that supports overloading wasn't
227 properly adding overload magic to the object due to a bug
228 in (at least) 5.8.8. We now use $_[1] directly which seems
229 to set the magic properly. (Sartak)
231 * Class::MOP::Attribute
232 - The process_accessors method is now private. A public alias
233 exists (and will stick around for a few releases), but it
234 warns that calling the public method is deprecated.
236 * Class::MOP::Method::Generated
237 - Removed the new and _new methods, since this is an abstract
238 base class, and all existing subclasses implement their own
242 - Stop is_class_loaded from thinking a class is loaded if it
243 only has an empty GV (Florian Ragwitz).
244 - Add a test for this (Yappo).
245 - Refactor get_all_package_symbols to allow short-circuiting
247 - Use this in is_class_loaded (Florian Ragwitz).
248 - Stop segfaulting when trying to get the name from a sub that's
249 still being compiled (Florian Ragwitz).
250 - Add tests for this (Florian Ragwitz).
251 - Prefix all public symbols with "mop_" (Florian Ragwitz).
252 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
253 - Simplify creating simple xs reader methods (Florian Ragwitz).
254 - Make everything compile with c++ compilers (Florian Ragwitz).
255 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
258 - Remove optional test plans for tests depending on Sub::Name as
259 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
262 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
264 0.78 Mon, February 23, 2009
265 * No changes from 0.77_01
267 0.77_01 Sun, February 22, 2009
269 - This package now requires its XS components. Not using
270 Sub::Name lead to different behavior and bugginess in the pure
271 Perl version of the code. A Moose test would fail when run
272 against the pure Perl version of this code.
274 * Class::MOP::Instance
275 - The inline_* methods now quote attribute names themselves, and
276 don't expect to receive a quoted value.
279 0.77 Sat, February 14, 2009
281 - Avoid assertion errors on debugging perls in is_class_loaded
285 - Fixed various corner cases where is_class_loaded incorrectly
286 returned true for a class that wasn't really loaded. (Dave
290 - Add get_all_method_names (Sartak)
291 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
293 * Class::MOP::Package
294 - Disable deprecated get_all_package_symbols in list
295 context. (Florian Ragwitz)
298 - Make sure we generate a BSD-compatible Makefile (Florian
302 - The misspelled "check_metaclass_compatability" method we've
303 kept around for backwards compat_i_bility will be removed in a
304 near future release. You've been warned.
306 0.76 Thu, January 22, 2009
307 * Class::MOP::Method::Generated
308 - Added new private methods to support code generation, which
309 are being used by Moose and can be used by MooseX
311 - Generated methods are now generated with a #line directive
312 reflecting the source of the generated method. (nothingmuch)
315 - Clarified documentation of methods that return
316 Class::MOP::Method objects. (doy)
319 - Clarified documentation of the metaclass cache methods. (Sartak)
322 - Add test showing how the xs Class::MOP::is_class_loaded can
323 be made to operate differently to the pure perl version (t0m)
325 0.75 Wed, December 31, 2008
327 - A class that was made immutable and then mutable could end up
328 sharing an immutable transformer object
329 (Class::MOP::Immutable) with other classes, leading to all
330 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
332 0.74 Tue, December 25, 2008
334 - Add an xs implementation of Class::MOP::is_class_loaded (closes
335 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
336 - Changed internals to make prehashing of hash keys easier and less
337 error-prone. (Florian Ragwitz)
339 - Fix documentation to show that around modifiers happen on both
340 sides of the modified method. (Dave Rolsky)
342 0.73 Tue, December 16, 2008
344 - Don't use Perl_mro_meta_init. It's not part of the public perl
345 api. Fixes failures to build on Win32 (RT #41750). (Florian
347 * t/082_get_code_info.t
348 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
349 munger anonymous subs when under -d and so making the tests
350 succeed in that case.
352 0.72 Mon, December 8, 2008
353 * Class::MOP::Package
354 - Pass options to _new, so subclass' attributes can be
357 - In the docs, indicate that package_name and name are required
358 when calling ->wrap (Stefan O'Rear)
360 0.71_02 Fri, December 5, 2008
361 * Class::MOP::Immutable
362 - Added a new attribute, inlined_constructor, which is true if
363 the constructor was inlined.
364 * Class::MOP::Package
365 - Make get_all_package_symbols return a hash ref in scalar
366 context and deprecate calling it in list context with a
367 warning. (Florian Ragwitz)
369 - Various improvements and refactoring, making things more robust and
370 easier to maintain. (Florian Ragwitz)
372 0.71_01 Wed, December 3, 2008
374 - Add an "execute" method to invoke the body so
375 we can avoid using the coderef overload (Sartak)
376 * Class::MOP::Immutable
377 - When we memoize methods, get their results lazily
378 to remove some compile-time cost (Sartak)
379 - Small speedup from eliminating several method
382 - Some small internal tweaks to try to reduce the number of
383 times we call get_method_map when bootstrapping the MOP. This
384 might make loading Class::MOP (and Moose) a little
385 faster. (Dave Rolsky)
386 - Implemented an optional XS version of get_method_map. Mostly
387 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
388 help form Florian Ragwitz. (Dave Rolsky)
389 - Make the behaviour of of get_all_package_symbols (and
390 therefore get_method_map) consistent for stub methods. Report
391 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
393 0.71 Wed November 26, 2008
396 - Actual package creation has moved upward from
397 Class to Module so that Moose roles can share
400 0.70_01 Mon, November 19, 2008
402 - Fixes for failures with blead (Florian Ragwitz)
403 - Silenced compiler warnings (Florian Ragwitz)
405 0.70 Fri, November 14, 2008
407 - Fixed an odd corner case where the XS version of
408 get_all_package_symbols could cause a segfault. This only
409 happened with inlined constants in Perl 5.10.0 (Florian
412 0.69 Fri, November 7, 2008
413 * Class::MOP::Method::Wrapped
414 - Added introspection methods for method modifiers (Dave Rolsky)
417 0.68 Fri October 24, 2008
419 - Make load_class require by file name instead of module name.
420 This stops confusing error messages when loading '__PACKAGE__'.
422 - Add load_one_class_of function to enable you to load one of a
423 list of classes, rather than having to call load_class multiple
424 times in an eval. (t0m)
426 0.67 Tue October 14, 2008
428 - Call a method on the class after setting the superclass list
429 so that we can get Perl to detect cycles before MRO::Compat
430 spirals into an infinite loop (sartak)
431 - Reported by Schwern, [rt.cpan.org #39001]
432 - In create(), pass unused options on to initialize()
433 - added test for this
435 0.66 Sat September 20, 2008
436 !! This release has an incompatible change regarding !!
437 introspection of a class's method with Class::MOP::Class !!
440 - We (us maintainers) now run all tests with XS and then without
441 XS, which should help us catch skew between the XS/pure Perl
445 ! The alias_method method has been deprecated. It now simply
446 calls add_method instead. There is no distinction between
447 aliased methods and "real" methods.
449 This means that methods added via alias_method now show up as
450 part of the class's method list/map. This is a backwards
451 incompatible change, but seems unlikely to break any
452 code. Famous last words. (Dave Rolsky)
455 - Fixed the spelling of "compatibility", but we still have a
456 "check_metaclass_compatability" method for backwards
459 0.65 Mon September 1, 2008
460 For those not following the series of dev releases, the changes
461 from 0.64 from 0.65 can mostly be summed up as a lot performance
462 improvements by nothingmuch, including new optional XS versions of
463 some methods. Also, Class::MOP now works _without_ any XS modules,
464 for sad systems without a compiler.
467 - Added name and package_name XS accessors, and make sure all
468 the XS and Perl versions work the same way. (Dave Rolsky)
471 - The XS versions of various methods just returned undef when
472 called class methods, rather than dying like the pure Perl
473 versions. (Dave Rolsky)
475 0.64_07 Fri August 29, 2008
477 - Silenced warnings that managed to break Moose tests when XS
478 was loaded. (Dave Rolsky)
479 - Some XS versions of methods were ignored because of typos in
480 MOP.xs. (Dave Rolsky)
482 0.64_06 Mon August 25, 2008
483 * Class::MOP (MOP.xs)
484 - Another MS VC++ fix, cannot declare a variable in the middle
485 of a scope (Taro Nishino).
487 0.64_05 Sun August 24, 2008
489 - None of the dev releases actually loaded the XS properly, but
490 we silently fell back to the pure Perl version of the
493 * Class::MOP (MOP.xs)
494 - Replaced some code that used functions not available on Visual
495 C++ with some Perl XS API bits (Dave Rolsky).
497 0.64_04 Sat August 23, 2008
499 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
501 * pod.t and pod_coveraget.t
502 - These are no longer shipped with the tarball because of bogus
503 failures from CPAN testers. (Dave Rolsky)
505 0.64_03 Thu August 21, 2008
506 * Class::MOP::Package
507 - Some (legit) code was misparsed by earlier 5.8.x
508 releases. (nothingmuch)
511 - Fix a constant in void context warning (nothingmuch)
513 0.64_02 Thu August 21, 2008
514 * Makefile.PL and Class::MOP
515 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
518 - Add missing prereqs that got lost in the switch away from
521 * Class::MOP::Instance
522 - New method - get_all_attributes (nothingmuch)
524 0.64_01 Wed August 20, 2008
526 - We now check to see if you have a compiler. If you don't, the
527 module installs without some XS bits, but will work the same
528 as with XS. This should make it easier to install on platforms
529 without a compiler (like Windows). (Dave Rolsky)
532 - Perl 6 style attribute naming replaced with sane style ('methods', not
533 '%!methods'). These changes should not impact any existing API uses.
537 - Quite a number of optimizations based on profiling, including
538 allowing constructors to take hash references instead of
539 hashes, duplicating some frequently used code in XS, and
540 making constructors immutable. These changes should not impact
541 any existing API uses. (nothingmuch)
544 - Constructors now respect the meta attributes of their subclasses,
545 facilitating MOP extensibility. More related changes will happen in the
546 next several releases. (nothingmuch)
549 - New method - get_all_methods, replaces the deprecated
550 compute_all_applicable_methods. get_all_attributes provided for
551 consistency (nothingmuch)
552 - New method - wrap_method was refactored out of get_method_map
554 - New API for meta instance invalidation - invalidate_meta_instance,
555 invalidate_meta_instances, add_dependent_meta_instance,
556 remove_dependent_meta_instance, called automatically when attribute
557 definitions change and allows notification of dependent subclasses.
560 0.64 Sun August 3, 2008
561 * Class::MOP::Immutable
562 - fixing subtle edge case in immutable when you
564 - clean up option processing (nothingmuch)
566 * Class::MOP::Instance
567 - inlined initialize slot didn't match
568 non-inlined (nothingmuch)
570 0.63 Mon July 7, 2008
572 - load_class will initialize a metaclass even if
573 the class is already loaded (sartak)
574 - load_class now returns the metaclass instance
575 instead of just 1 (sartak)
578 - better error messages (sartak and Dave Rolsky)
580 0.62 Wed June 18, 2008
581 - in is_class_loaded, recognize scalar references (as opposed to globs) in
582 the symbol table as methods (these are optimized constant subs)
584 0.61 Fri. June 13, 2008
585 - Okay, lets give this another try and see if PAUSE
586 recognizes it correct this time.
588 0.60 Thurs. Jun 12, 2008
589 - Fixed a version number issue by bumping all modules
592 0.59 Thurs. Jun 12, 2008
593 !! Several fixes resulting in yet another 25-30% speedup !!
596 - now stores the instance of the instance
597 metaclass to avoid needless recomputation
598 and deletes it when the cache is blown
599 - introduce methods to query Class::MOP::Class for
600 the options used to make it immutable as well as
601 the proper immutable transformer. (groditi)
603 * Class::MOP::Package
604 - {add, has, get, remove}_package_symbol all
605 now accept a HASH ref argument as well as the
606 string. All internal usages now use the HASH
610 - MOP.xs does sanity checks on the coderef
612 - is_class_loaded check now uses code that
613 was improved in Moose's ClassName type
615 - nonsensical (undef, empty, reference) class
616 names now throw a more direct error in
618 - tests for this and other aspects of
624 Class::MOP::Method::Wrapped
625 Class::MOP::Attribute
626 - switched usage of reftype to ref because
629 0.58 Thurs. May 29, 2008
630 (late night release engineering)--
632 - fixing the version is META.yml, no functional
633 changes in this release
635 0.57 Wed. May 28, 2008
636 !! Several speedups resulting in 20-25% speedups !!
637 || (thanks to konobi, groditi, mst & CataMoose) !!
640 - made get_method_map use list_all_package_symbols
641 instead of manually grabbing each symbol
642 - streamlining &initialize somewhat, since it gets
645 * Class::MOP::Package
646 - made {get, has}_package_symbol not call
648 - inlining a few calls to &name with
649 direct HASH access key access
650 - added get_all_package_symbols to fetch
651 a HASH of items based on a type filter
652 similar to list_all_package_symbols
653 - added tests for this
656 Class::MOP::Method::Constructor
657 Class::MOP::Method::Generated
658 Class::MOP::Method::Accessor
659 - added more descriptive error message to help
660 keep people from wasting time tracking an error
661 that is easily fixed by upgrading.
663 * Class::MOP::Immutable
664 - Don't inline a destructor unless the user actually
666 - added tests for this
668 0.56 Saturday, May 24, 2008
670 - we now get the &check_package_cache_flag
671 function from MRO::Compat
672 - All XS based functionality now has a
673 Pure Perl alternative
674 - the CLASS_MOP_NO_XS environment variable
675 can now be used to force non-XS versions
678 * Class::MOP::Attribute
679 - add has_read_method and has_write_method
680 - get_{read,write}_method_ref now wraps the
681 anon-sub ref in the method metaclass when
683 - added tests for this
685 * Class::MOP::Immutable
686 - added the ability to "wrap" methods when
687 making the class immutable
690 - now handling the edge case of ->meta->identifier
691 dying by wrapping add_package_symbol to specifically
692 allow for it to work.
693 - added tests for this
695 * Class::MOP::Attribute
697 Class::MOP::Immutable
698 - any time a method meta object is constructed
699 we make sure to pass the correct package and
700 method name information
703 Class::MOP::Method::Wrapped
704 Class::MOP::Method::Generated
705 Class::MOP::Method::Accessor
706 Class::MOP::Method::Consructor
707 - the &wrap constructor method now requires that a
708 'package_name' and 'name' attribute are passed. This
709 is to help support the no-XS version, and will
710 throw an error if these are not supplied.
711 - all these classes are now bootstrapped properly
712 and now store the package_name and name attributes
715 ~ Build.PL has been removed since the
716 Module::Install support has been removed
718 0.55 Mon. April 28, 2008
719 - All classes now have proper C3 MRO support
720 - added MRO::Compat as a dependency to allow
721 for the C3 MRO support to Just Work in all
725 - rebless_instance now returns the instance
726 it has just blessed, this is mostly to
728 - set the attr correctly in rebless_instance
729 when it has no init_arg
730 - tweaked &linear_isa and &class_precedence_list
731 to support c3 classes.
733 0.54 Fri. March, 14, 2008
736 - making sure that load_class never gets
737 passed a value from @_ or $_ to squash
738 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
741 - make_{immutable,mutable} now return 1
743 - improved error handling in ->create method
744 - rebless_instance now takes extra params which
745 will be used to populate values
746 - added tests for this
749 - localizing the Data::Dumper configurations so
750 that it does not pollute others (RT #33509)
756 Class::MOP::Attribute
757 - these classes no longer define their own ->meta,
758 but instead just inherit from Class::MOP::Object
760 * Class::MOP::Instance
761 Class::MOP::Immutable
762 - these classes now inherit from Class::MOP::Object
765 - fixed the filename length on several
766 test files so we install on VMS better
768 - fixed incorrect use of catdir when it
769 should be catfile (RT #32385)

772 ~~ several doc. fixes and updates ~~
775 Class::MOP::Method::Constructor
776 Class::MOP::Attribute
777 - making init_arg accept an undefined value
778 to indicate that no constructor args can
779 be passed (thanks to nothingmuch)
780 - added tests for this
781 - added attribute initializer attribute (rjbs)
784 - making this use the new init_arg => undef
785 feature instead of the silly hack from
786 before (thanks to nothingmuch)
788 0.52 Tues. Jan. 22, 2008
790 - fixed bug in rebless_instance
793 * Class::MOP::Method::Constructor
794 - removed assumptions about the existence of
797 0.51 Mon. Jan. 14, 2008
798 ~~~ some misc. doc. fixes ~~~
799 ~~ updated copyright dates ~~
802 - now sets the IS_RUNNING_ON_5_10
803 constant so that we can take advantage
804 of some of the nice bits of 5.10
807 - uses the IS_RUNNING_ON_5_10 flag to
808 optimize the &linearized_isa method
809 and avoid the hack/check for circular
810 inheritence in &class_precedence_list
811 - added rebless_instance method (Sartak)
812 - added tests for this
814 * Class::MOP::Immutable
815 - the immutable class now keeps track of
816 the transformer which immutablized it

829 * Class::MOP::Immutable
830 - fixed a bug (see above)
832 * Class::MOP::Attribute
835 0.49 Fri. Dec. 14, 2007
836 !! Class::MOP now loads 2 x faster !!
837 !! with XS speedups (thanks konobi) !!
840 - removed the dependency on B
841 - added two XS functions (thanks konobi)
842 - get_code_info($code) which replaces all
843 the B fiddling we were doing with
844 faster/leaner XS level fiddling
845 - check_package_cache_flag($pkg_name) which
846 returns the PL_sub_generation variable to
847 be used to help manage method caching.
850 In 5.10 or greater this will actually
851 use the mro::get_pkg_gen instead to give
852 even more accurate caching information.
853 blblack++ for that stuff :)
856 - added the &subclasses method (thanks rlb)
857 - added the update_package_cache_flag and
858 reset_package_cache_flag which help keep
859 track of when we need to re-fetch the
861 - Several small improvements to take advantage
862 of the new method map caching features
864 0.48 Mon. Nov. 26, 2007
865 * Class::MOP::Attribute
866 - fixed get_read/write_method to handle the
867 HASH ref case, which makes the

874 - added more tests for this
876 0.46 Fri. Nov. 23, 2007
878 - added the linearized_isa method instead of constantly
879 pruning duplicate classes (this will be even more
880 useful in the 5.10-compat version coming soon)
882 * Class::MOP::Attribute
883 - added the get_read_method_ref and get_write_method_ref
884 methods which allow you to retrieve a CODE ref which
885 can always be used to read or write an attribute.
887 0.45 Thurs. Nov. 13, 2007
888 * Class::MOP::Attribute
889 - Fix error message on confess (groditi)
891 0.44 Thurs. Nov. 13, 2007

894 0.43 Thurs. Nov. 13, 2007
896 - Add support for the 'builder' attribute (groditi)
899 - optimise metaclass-already-exists check in
900 construct_class_instance (groditi)
901 - duplicate check into initialize to save a
902 call through (groditi)
904 * Class::MOP::Attribute
905 - Add support for the 'builder' attribute (groditi)
906 - Make predicates check for the existence of a value, not whether
907 it is defined (groditi)
909 * Class::MOP::Instance
910 - Make predicates check for the existence of a value, not whether
911 it is defined (groditi)
913 * Class::MOP::Method::Accessor
914 - made this a subclass of Class::MOP::Method::Generated
915 - removed the relevant attributes
917 * Class::MOP::Method::Constructor
918 - fixed the cached values we had to be more sane
919 - made this a subclass of Class::MOP::Method::Generated
920 - fixed generated constructor so it properly handles
922 - added tests for this
923 - added the option to allow for both inlined and
924 non-inlined constructors.
925 - Update inlined methods for builder and predicate changes (groditi)
927 * Class::MOP::Method::Generated
928 - added this class as an abstract base for the
929 Class::MOP::Method::{Constructor,Accessor} classes
930 - added tests for this
933 - Alter tests (005, 014 020, 021) for new builder addition (groditi)

939 0.42 Mon. July 16, 2007
940 !!! Horray for mst, he fixed it !!!
942 * Class::MOP::Package
943 - alter symbol table handling to deal with 5.8.x and 5.9.x
946 - Get rid of the crappy workaround from 0.40/41
948 0.41 Sun. July 15, 2007
950 Arghh!!! My TODO test didn't work, so I handle
951 it manually now so that people can use this
952 with 5.9.5/bleadperl without issue.
954 0.40 Tues, July 3, 2007
956 ~ marked a test in 003_methods.t as TODO
957 for perl 5.9.5 (this test is irrelvant to
958 the module functioning on 5.9.5 for the most
961 0.39 Mon. June 18, 2007
962 * Class::MOP::Immutable
963 - added make_metaclass_mutable + docs (groditi)
964 - removed unused variable
965 - added create_immutable_transformer
966 necessary for sane overloading of immutable behavior
967 - tests for this (groditi)
970 - Immutability can now be undone,
971 added make_mutable + tests + docs (groditi)
972 - Massive changes to the way Immutable is done
973 for details see comments next to make_immutable
974 This fixes a bug where custom metaclasses broke
975 when made immutable. We are now keeping one immutable
976 metaclass instance per metaclass instead of just one
977 to prevent isa hierarchy corruption. Memory use will go
978 up, but I suspect it will be neglible.
979 - New tests added for this behavior. (groditi)
981 0.38 Thurs. May 31, 2007
982 ~~ More documentation updates ~~
984 * Class::MOP::Package
985 - we now deal with stub methods properly

987 - fixed some tests failing on 5.9.5 (thanks blblack)
989 * Class::MOP::Attribute
990 - added get_read_method and get_write_method
991 thanks to groditi for this code, tests
993 - added tests and POD for this
996 - fixed RT issue #27329, clone object now
997 handles undef values correctly.
998 - added tests for this
999 - Corrected anon-class handling so that they
1000 will not get reaped when instances still
1001 exist which need to reference them. This is
1002 the correct behavior, hopefully this is an
1003 obscure enough feature that there are not too
1004 many work arounds out in the wild.
1005 - added tests for this by groditi
1006 - updated docs to explain this
1009 - load custom metaclasses automatically (thanks groditi)
1010 - added tests for this behavior
1012 0.37 Sat. March 10, 2007

1021 avoid setting off bool-overloads (found by Carl Franks)
1025 - bad name in a test, causing meaningless failuress.
1030 ~~ GLOBAL CHANGES ~~
1031 - All attribute names are now consistent and follow Perl 6
1032 style (prefixed with the sigil, and ! as the twigil for
1033 private attrs). This should not affect any code, unless
1034 you broke encapsulation, in which case, it is your problem
1037 !! Class::MOP::Class::Immutable has been removed
1039 * Class::MOP::Method::Constructor
1040 - this has been moved out of Class::MOP::Class::Immutable
1041 and is a proper subclass of Class::MOP::Method now.
1044 - this module now uses Class::MOP::Immutable for the
1045 immutable transformation instead of
1046 Class::MOP::Class::Immutable.
1048 + Class::MOP::Immutable
1049 - this module now controls the transformation from a mutable
1050 to an immutable version of the class. Docs for this will
1051 be coming eventually.
1054 0.36 Sun. Nov. 5, 2006
1056 - added a few 'no warnings' lines to keep annoying
1057 (and meaningless) warnings from chirping during
1061 - some more bootstrapping is now done on the new
1064 * Class::MOP::Class::Immutable
1066 - constructor generation is now handled by
1067 the Class::MOP::Method::Constructor class
1069 * Class::MOP::Method::Constructor
1070 - created this to handle constructor generation
1071 in Class::MOP::Class::Immutable
1073 * Class::MOP::Attribute
1075 - attributes now delegate to the
1076 Class::MOP::Method::Accessor to generate
1079 * Class::MOP::Method::Accessor
1080 - all accessor generation functions from
1081 Class::MOP::Attribute have been moved here

1097 - adjusted tests for this
1098 - added the Class::MOP::Instance attributes

1109 - changed how methods are dealt with to
1110 encapsulate most of the work into the
1111 &get_method_map method
1112 - made several adjustments for the change
1113 in Class::MOP::Method
1114 - &add_attribute now checks if you are adding
1115 a duplicate name, and properly removes the
1116 old one before installing the new one
1117 - added tests for this
1118 - adjusted docs for this
1120 * Class::MOP::Class::Immutable
1121 - added caching of &get_method_map

1127 &list_all_package_symbols
1129 0.34 Sat. Aug. 26, 2006
1131 - added the %:methods attribute, which like
1132 the $:version and such just actually goes
1133 to the symbol table to get it's stuff.
1134 However, it makes the MOP more complete.
1136 - The &create method now requires that all
1137 but the package name now is passed in as
1138 named parameters. See docs for more info.
1139 - updated docs and tests for this
1141 * Class::MOP::Object
1142 - added &dump method to easily Data::Dumper

1165 - added tests for this
1167 * Class::MOP::Package
1168 - fixed an issue with perl 5.8.1 and how it deals
1169 with symbol tables. The namespace hash is now
1170 always reloaded from the symbol table.
1172 ~ lots of misc. documentation cleanup
1174 0.32 Sat. Aug. 12, 2006
1175 + added Class::MOP::Object so that the
1176 metamodel is more complete (and closer
1177 to what Perl 6 will probably be).
1179 * Class::MOP::Package
1180 - refactored entire class, this is now
1181 the primary gateway between the metaclass
1182 and the Perl 5 symbol table
1183 - added many tests for this
1184 - this class is now a subclass of
1186 - added some tests to reflect this

1190 use Class::MOP::Package methods instead
1192 * Class::MOP::Module
1193 - adding the $:version attribute in the bootstrap
1194 so that Module has a version as an attribute
1195 - see comment in Class::MOP for details
1196 - added the $:authority attribute to this module
1197 as well as an &identifier method, to bring us
1198 ever closer to Perl 6 goodness
1199 - I have added $AUTHORITY to all the modules
1200 - added tests for this

1216 anywhere within the class hierarchy
1218 * Class::MOP::Attribute
1219 - added &set_value and &get_value for getting
1220 the value of the attribute for a particular
1223 0.30 Wed. July 5, 2006
1224 ---------------------------------------
1225 This is the first version of Class::MOP
1226 to introduce the immutable features which
1227 will be used for optimizating the MOP.
1228 This support should still be considered
1229 experimental, but moving towards stability.
1230 ---------------------------------------
1232 * Created Class::MOP::Class::Immutable
1234 * Created the Class::MOP::Package and
1235 Class::MOP::Module classes to more
1236 closely conform to Perl 6's meta-model
1239 - now inherits from Class::MOP::Module
1240 - several methods moved to ::Module and
1241 ::Package and now inherited
1242 - added tests for this
1244 * Class::MOP::Instance
1245 - added an is_inlinable method to allow other
1246 classes to check before they attempt to optimize.
1247 - added an inline_create_instance to inline
1248 instance creation (of course)
1251 - the Class::MOP::Class::*_package_variable
1252 methods are all now methods of Class::MOP::Package
1253 and called *_package_symbol instead. This is
1254 because they are now more general purpose symbol
1255 table manipulation methods.
1257 0.29_02 Thurs. June 22, 2006
1258 ++ DEVELOPER RELEASE ++
1260 - small change in &create so that it behaves

1264 0.29_01 Fri. May 12, 2006
1265 ++ DEVELOPER RELEASE ++
1266 - This release works in combination with
1267 Moose 0.09_01, it is a developer release

1316 - attribute slot initialization is now the responsibility
1317 of the attribute itself, and construct_instance now
1318 delegates appropriately
1320 * Class::MOP::Attribute
1321 - attribute slot initialization is now the responsibility
1322 of the attribute itself, so we added a method for it
1323 called initialize_instance_slot

1352 0.21 Wed. March 15, 2006
1354 - fixed issue where metaclasses are reaped from

1380 - &add_after_method_modifier
1381 - &add_around_method_modifier
1382 - added tests and docs for these
1383 - added &find_next_method_by_name which finds the
1384 equivalent of SUPER::method_name
1386 0.12 Thurs. Feb 23, 2006
1387 - reduced the dependency on B, no need to always
1391 - added docs to the C3 method dispatch order test

1397 - added example of changing method dispatch order to C3
1400 - changed how clone_instance behaves, it now only does a
1401 shallow clone (see docs for more details)
1402 - added docs and tests
1404 0.10 Tues Feb. 14, 2006
1405 ** This release was mostly about writing more tests and
1406 cleaning out old and dusty code, the MOP should now
1407 be considered "ready to use".
1409 - adding more tests to get coverage up a little higher,
1410 mostly testing errors and edge cases.
1411 - test coverage is now at 99%
1414 - no longer optionally exports to UNIVERSAL::meta or
1415 creates a custom metaclass generator, use the

1429 0.06 Thurs Feb. 9, 2006
1431 - adding new metaclass pragma to make setting up the
1432 metaclass a little more straightforward
1435 - clean up bootstrapping to include more complete
1436 attribute definitions for Class::MOP::Class and
1437 Class::MOP::Attribute (accessors, readers, writers,
1438 etc.) ... it is redundant, but is useful meta-info
1442 - fixing minor meta-circularity issue with &meta, it
1443 is now more useful for subclasses
1444 - added &get_attribute_map as an accessor for the
1445 hash of attribute meta objects
1446 - &compute_all_applicable_attributes now just returns
1447 the attribute meta-object, rather than the HASH ref
1448 since all the same info can be gotten from the
1449 attribute meta-object itself
1450 - updated docs & tests to reflect
1451 - added &clone_instance method which does a deep clone
1452 of the instance structure created by &construct_instance
