1 Revision history for Perl extension Class-MOP.
6 - Anonymous classes were not destroyed properly when they went
7 out of scope, leading to a memory leak. RT #47480 (Goro Fuji).
11 - Move get_method_map and its various scaffolding into Package. (hdp)
15 * Class::MOP::Class::Immutable::Trait
16 - Made the Trait act like a role with a bunch of "around"
17 modifiers, rather than sticking it in the inheritance
18 hierarchy. This fixes various problems that caused with
19 metaclass compatibility, which broke Fey::ORM.
22 - Allow a blessed code reference as the method body. Fixes a
23 problem interaction with MooseX::Types. (ash)
25 * Class::MOP::Instance
26 - add inline version of rebless_instance_structure. (doy)
27 - change inline_slot_access to use single quotes (gphat)
29 0.88 Tue, Jun 23, 2009
31 - Moved the __INSTANCE__ parameter to _construct_instance from
33 - Fixed some issues involving metaclasses of metaclasses and
36 0.87 Sun, Jun 21, 2009
38 - Made sure to always local-ize $@ and $SIG{__DIE__} before
39 calling an eval. Fixes RT #45973.
42 - Synced docs about immutability with the current reality (which
43 changed back in 0.82_01)
44 - Removed the immutable_transformer method, which had been
45 returning undef since 0.82_01 anyway.
48 - Got rid of tests which needed Moose and improved testing of
49 constructor/destructor inlining warnings. Fixes RT #47119.
51 0.86 Tue, Jun 16, 2009
53 - If you redefined a subroutine at runtime and then wrapped it
54 with a method modifier, the modifier could in some cases wrap
55 the original version of the subroutine. Fixes RT #46957.
58 - make_immutable issues a warning instead of overriding an
59 existing DESTROY method (Dylan William Hardison). Fixes RT
63 * Class::MOP::Attribute
64 - Allow default values to be Class::MOP::Methods. (Florian
66 - Test the above. (Rhesa Rozendaal)
67 - Tweak original commit so the intent matches the accepted
68 behavior (Nicholas Perez)
71 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
74 - Add direct_subclasses method (Sartak)
75 - Tests for subclasses and direct_subclasses (Sartak)
76 - subname is no longer used unconditionally in add_method, but
77 only if the code reference's name is '__ANON__' (nothingmuch)
78 - Add a hook for _superclasses_updated (Sartak)
81 - Remove long, old warning about possibly outdated modules
84 0.84 Tue, May 12, 2009
86 - Depend on Text::Exception 0.27 to avoid failing tests ond old
90 - Made is_class_loaded a little stricter. It was reporting that
91 a class was loaded if it merely had an @ISA variable in its
92 stash. Now it checks that the @ISA var has elements in it.
93 - Deprecate in_global_destruction and subname re-exporting
97 - Explicitly use Devel::GlobalDestruction and Sub::Name
100 * Class::MOP::Package
101 - Disable prototype mismatch warnings for add_package_symbol.
104 - Add test for finding methods from $meta->name->meta before immutable,
107 0.83 Mon, April 27, 2009
109 - Fix segfault when calling get_method_map on a metaclass for an empty
112 0.82_02 Fri, April 24, 2009
113 * Class::MOP::Method::Inlined
114 - Don't inline if the expected method is not defined at all (happens with
115 e.g. Moose::Object::_new is the expected method due to an overridden
118 - Some tests were trying to load Class::MOP::Immutable, which
119 was removed in 0.82_01.
121 0.82_01 Thu, April 23, 2009
122 * Class::MOP::Immutable (and others)
123 - Refactor the immutability system to use a pre-defined class
124 for the immutable metaclass of Class::MOP::Class::Immutable::$class
125 - Rather than generating methods into this class every time, use
126 a Trait (basic mixin) to supply the cached methods
127 - Remove the hack that returns the mutable metaclass for
128 metacircularity in order to provide consistent meta-metaclasses
129 for the Moose compatibility handling code
130 (mst broke it, nothingmuch fixed it)
132 0.82 Mon, April 20, 2009
134 - The deprecation wrappers for some renamed methods were not
135 passing arguments to the new method. (nothingmuch)
137 * Class::MOP::Immutable
138 - Warn during immutablization if the local class provides its own
139 constructor, to parallel the warning in Moose when a superclass
140 provides its own constructor (doy)
142 0.81 Tue, April 7, 2009
145 * Class::MOP::Instance
146 * Class::MOP::Attribute
147 * Class::MOP::Method::Accessor
148 * Class::MOP::Method::Constructor
149 - Include stack traces in the deprecation warnings introduced in
150 0.80_01. (Florian Ragwitz)
153 - Avoid c compiler warnings by declaring some unused function
154 arguments. (Florian Ragwitz)
156 0.80_01 Sun, April 5, 2009
158 - Make sure to preserve any compiler flags already defined in
159 Config.pm. Patch by Vincent Pit. RT #44739.
161 * Many methods have been renamed with a leading underscore, and a
162 few have been deprecated entirely. The methods with a leading
163 underscore are consider "internals only". People writing
164 subclasses or extensions to Class::MOP should feel free to
165 override them, but they are not for "public" use.
168 - construct_class_instance => _construct_class_instance (use new_object)
169 - construct_instance => _construct_instance (use new_object)
170 - check_metaclass_compatibility => _check_metaclass_compatibility
171 - create_meta_instance => _create_meta_instance (use get_meta_instance)
172 - clone_instance => _clone_instance (use clone_object)
173 - compute_all_applicable_methods is deprecated, use get_all_methods
174 - compute_all_applicable_attributes is deprecated, use get_all_attributes
176 - Class::MOP::Instance
177 - bless_instance_structure is deprecated and will be removed
181 - create has been renamed to _instantiate_module. This method
182 does not construct an object, it evals some code that
183 creates the relevant package in Perl's symbol table.
185 - Class::MOP::Method::Accessor
186 - initialize_body => _initialize_body (this is always called
187 when an object is constructed)
188 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
190 - Class::MOP::Method::Constructor
191 - initialize_body => _initialize_body (this is always called
192 when an object is constructed)
193 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
194 - attributes => _attributes
195 - meta_instance => _meta_instance
197 0.80 Wed, April 1, 2009
199 - Call user_class->meta in fewer places, with the eventual goal
200 of allowing the user to rename or exclude ->meta
201 altogether. Instead uses Class::MOP::class_of. (Sartak)
204 - New class_of function that should be used to retrieve a
205 metaclass. This is unlike get_metaclass_by_name in that it
206 accepts instances, not just class names. (Sartak)
209 - load_first_existing_class didn't actually load the first
210 existing class; instead, it loaded the first existing and
211 compiling class. It now throws an error if a class exists (in
212 @INC) but fails to compile. (hdp)
216 - we had some semi-buggy code that purported to provide a
217 HAS_ISAREV based on whether mro had get_isarev (due to an
218 oversight, it always returned 1). Since mro and MRO::Compat
219 have always had get_isarev, HAS_ISAREV was pointless. This
220 insight simplified the subclasses method by deleting the
221 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
223 0.79 Fri, March 29, 2009
224 * No changes from 0.78_02.
226 0.78_02 Thu, March 26, 2009
228 * Class::MOP::Immutable
229 - A big backwards-incompatible refactoring of the Immutable API,
230 and the make_immutable/make_mutable pieces of the Class
231 API. The core __PACKAGE__->meta->make_immutable API remains
232 the same, however, so this should only affect the most
236 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
237 has been fixed to be backwards compatible with 5.8.x.
240 - Add a hook for rebless_instance_away (Sartak)
241 - Use blessed instead of ref to get an instance's class name
242 in rebless_instance. (Sartak)
244 0.78_01 Wed, March 18, 2009
246 - Revised and reorganized all of the API documentation. All
247 classes now have (more or less) complete API documentation.
250 * Class::MOP::Instance
251 - Reblessing into a package that supports overloading wasn't
252 properly adding overload magic to the object due to a bug
253 in (at least) 5.8.8. We now use $_[1] directly which seems
254 to set the magic properly. (Sartak)
256 * Class::MOP::Attribute
257 - The process_accessors method is now private. A public alias
258 exists (and will stick around for a few releases), but it
259 warns that calling the public method is deprecated.
261 * Class::MOP::Method::Generated
262 - Removed the new and _new methods, since this is an abstract
263 base class, and all existing subclasses implement their own
267 - Stop is_class_loaded from thinking a class is loaded if it
268 only has an empty GV (Florian Ragwitz).
269 - Add a test for this (Yappo).
270 - Refactor get_all_package_symbols to allow short-circuiting
272 - Use this in is_class_loaded (Florian Ragwitz).
273 - Stop segfaulting when trying to get the name from a sub that's
274 still being compiled (Florian Ragwitz).
275 - Add tests for this (Florian Ragwitz).
276 - Prefix all public symbols with "mop_" (Florian Ragwitz).
277 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
278 - Simplify creating simple xs reader methods (Florian Ragwitz).
279 - Make everything compile with c++ compilers (Florian Ragwitz).
280 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
283 - Remove optional test plans for tests depending on Sub::Name as
284 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
287 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
289 0.78 Mon, February 23, 2009
290 * No changes from 0.77_01
292 0.77_01 Sun, February 22, 2009
294 - This package now requires its XS components. Not using
295 Sub::Name lead to different behavior and bugginess in the pure
296 Perl version of the code. A Moose test would fail when run
297 against the pure Perl version of this code.
299 * Class::MOP::Instance
300 - The inline_* methods now quote attribute names themselves, and
301 don't expect to receive a quoted value.
304 0.77 Sat, February 14, 2009
306 - Avoid assertion errors on debugging perls in is_class_loaded
310 - Fixed various corner cases where is_class_loaded incorrectly
311 returned true for a class that wasn't really loaded. (Dave
315 - Add get_all_method_names (Sartak)
316 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
318 * Class::MOP::Package
319 - Disable deprecated get_all_package_symbols in list
320 context. (Florian Ragwitz)
323 - Make sure we generate a BSD-compatible Makefile (Florian
327 - The misspelled "check_metaclass_compatability" method we've
328 kept around for backwards compat_i_bility will be removed in a
329 near future release. You've been warned.
331 0.76 Thu, January 22, 2009
332 * Class::MOP::Method::Generated
333 - Added new private methods to support code generation, which
334 are being used by Moose and can be used by MooseX
336 - Generated methods are now generated with a #line directive
337 reflecting the source of the generated method. (nothingmuch)
340 - Clarified documentation of methods that return
341 Class::MOP::Method objects. (doy)
344 - Clarified documentation of the metaclass cache methods. (Sartak)
347 - Add test showing how the xs Class::MOP::is_class_loaded can
348 be made to operate differently to the pure perl version (t0m)
350 0.75 Wed, December 31, 2008
352 - A class that was made immutable and then mutable could end up
353 sharing an immutable transformer object
354 (Class::MOP::Immutable) with other classes, leading to all
355 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
357 0.74 Tue, December 25, 2008
359 - Add an xs implementation of Class::MOP::is_class_loaded (closes
360 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
361 - Changed internals to make prehashing of hash keys easier and less
362 error-prone. (Florian Ragwitz)
364 - Fix documentation to show that around modifiers happen on both
365 sides of the modified method. (Dave Rolsky)
367 0.73 Tue, December 16, 2008
369 - Don't use Perl_mro_meta_init. It's not part of the public perl
370 api. Fixes failures to build on Win32 (RT #41750). (Florian
372 * t/082_get_code_info.t
373 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
374 munger anonymous subs when under -d and so making the tests
375 succeed in that case.
377 0.72 Mon, December 8, 2008
378 * Class::MOP::Package
379 - Pass options to _new, so subclass' attributes can be
382 - In the docs, indicate that package_name and name are required
383 when calling ->wrap (Stefan O'Rear)
385 0.71_02 Fri, December 5, 2008
386 * Class::MOP::Immutable
387 - Added a new attribute, inlined_constructor, which is true if
388 the constructor was inlined.
389 * Class::MOP::Package
390 - Make get_all_package_symbols return a hash ref in scalar
391 context and deprecate calling it in list context with a
392 warning. (Florian Ragwitz)
394 - Various improvements and refactoring, making things more robust and
395 easier to maintain. (Florian Ragwitz)
397 0.71_01 Wed, December 3, 2008
399 - Add an "execute" method to invoke the body so
400 we can avoid using the coderef overload (Sartak)
401 * Class::MOP::Immutable
402 - When we memoize methods, get their results lazily
403 to remove some compile-time cost (Sartak)
404 - Small speedup from eliminating several method
407 - Some small internal tweaks to try to reduce the number of
408 times we call get_method_map when bootstrapping the MOP. This
409 might make loading Class::MOP (and Moose) a little
410 faster. (Dave Rolsky)
411 - Implemented an optional XS version of get_method_map. Mostly
412 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
413 help form Florian Ragwitz. (Dave Rolsky)
414 - Make the behaviour of of get_all_package_symbols (and
415 therefore get_method_map) consistent for stub methods. Report
416 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
418 0.71 Wed November 26, 2008
421 - Actual package creation has moved upward from
422 Class to Module so that Moose roles can share
425 0.70_01 Mon, November 19, 2008
427 - Fixes for failures with blead (Florian Ragwitz)
428 - Silenced compiler warnings (Florian Ragwitz)
430 0.70 Fri, November 14, 2008
432 - Fixed an odd corner case where the XS version of
433 get_all_package_symbols could cause a segfault. This only
434 happened with inlined constants in Perl 5.10.0 (Florian
437 0.69 Fri, November 7, 2008
438 * Class::MOP::Method::Wrapped
439 - Added introspection methods for method modifiers (Dave Rolsky)
442 0.68 Fri October 24, 2008
444 - Make load_class require by file name instead of module name.
445 This stops confusing error messages when loading '__PACKAGE__'.
447 - Add load_one_class_of function to enable you to load one of a
448 list of classes, rather than having to call load_class multiple
449 times in an eval. (t0m)
451 0.67 Tue October 14, 2008
453 - Call a method on the class after setting the superclass list
454 so that we can get Perl to detect cycles before MRO::Compat
455 spirals into an infinite loop (sartak)
456 - Reported by Schwern, [rt.cpan.org #39001]
457 - In create(), pass unused options on to initialize()
458 - added test for this
460 0.66 Sat September 20, 2008
461 !! This release has an incompatible change regarding !!
462 introspection of a class's method with Class::MOP::Class !!
465 - We (us maintainers) now run all tests with XS and then without
466 XS, which should help us catch skew between the XS/pure Perl
470 ! The alias_method method has been deprecated. It now simply
471 calls add_method instead. There is no distinction between
472 aliased methods and "real" methods.
474 This means that methods added via alias_method now show up as
475 part of the class's method list/map. This is a backwards
476 incompatible change, but seems unlikely to break any
477 code. Famous last words. (Dave Rolsky)
480 - Fixed the spelling of "compatibility", but we still have a
481 "check_metaclass_compatability" method for backwards
484 0.65 Mon September 1, 2008
485 For those not following the series of dev releases, the changes
486 from 0.64 from 0.65 can mostly be summed up as a lot performance
487 improvements by nothingmuch, including new optional XS versions of
488 some methods. Also, Class::MOP now works _without_ any XS modules,
489 for sad systems without a compiler.
492 - Added name and package_name XS accessors, and make sure all
493 the XS and Perl versions work the same way. (Dave Rolsky)
496 - The XS versions of various methods just returned undef when
497 called class methods, rather than dying like the pure Perl
498 versions. (Dave Rolsky)
500 0.64_07 Fri August 29, 2008
502 - Silenced warnings that managed to break Moose tests when XS
503 was loaded. (Dave Rolsky)
504 - Some XS versions of methods were ignored because of typos in
505 MOP.xs. (Dave Rolsky)
507 0.64_06 Mon August 25, 2008
508 * Class::MOP (MOP.xs)
509 - Another MS VC++ fix, cannot declare a variable in the middle
510 of a scope (Taro Nishino).
512 0.64_05 Sun August 24, 2008
514 - None of the dev releases actually loaded the XS properly, but
515 we silently fell back to the pure Perl version of the
518 * Class::MOP (MOP.xs)
519 - Replaced some code that used functions not available on Visual
520 C++ with some Perl XS API bits (Dave Rolsky).
522 0.64_04 Sat August 23, 2008
524 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
526 * pod.t and pod_coveraget.t
527 - These are no longer shipped with the tarball because of bogus
528 failures from CPAN testers. (Dave Rolsky)
530 0.64_03 Thu August 21, 2008
531 * Class::MOP::Package
532 - Some (legit) code was misparsed by earlier 5.8.x
533 releases. (nothingmuch)
536 - Fix a constant in void context warning (nothingmuch)
538 0.64_02 Thu August 21, 2008
539 * Makefile.PL and Class::MOP
540 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
543 - Add missing prereqs that got lost in the switch away from
546 * Class::MOP::Instance
547 - New method - get_all_attributes (nothingmuch)
549 0.64_01 Wed August 20, 2008
551 - We now check to see if you have a compiler. If you don't, the
552 module installs without some XS bits, but will work the same
553 as with XS. This should make it easier to install on platforms
554 without a compiler (like Windows). (Dave Rolsky)
557 - Perl 6 style attribute naming replaced with sane style ('methods', not
558 '%!methods'). These changes should not impact any existing API uses.
562 - Quite a number of optimizations based on profiling, including
563 allowing constructors to take hash references instead of
564 hashes, duplicating some frequently used code in XS, and
565 making constructors immutable. These changes should not impact
566 any existing API uses. (nothingmuch)
569 - Constructors now respect the meta attributes of their subclasses,
570 facilitating MOP extensibility. More related changes will happen in the
571 next several releases. (nothingmuch)
574 - New method - get_all_methods, replaces the deprecated
575 compute_all_applicable_methods. get_all_attributes provided for
576 consistency (nothingmuch)
577 - New method - wrap_method was refactored out of get_method_map
579 - New API for meta instance invalidation - invalidate_meta_instance,
580 invalidate_meta_instances, add_dependent_meta_instance,
581 remove_dependent_meta_instance, called automatically when attribute
582 definitions change and allows notification of dependent subclasses.
585 0.64 Sun August 3, 2008
586 * Class::MOP::Immutable
587 - fixing subtle edge case in immutable when you
589 - clean up option processing (nothingmuch)
591 * Class::MOP::Instance
592 - inlined initialize slot didn't match
593 non-inlined (nothingmuch)
595 0.63 Mon July 7, 2008
597 - load_class will initialize a metaclass even if
598 the class is already loaded (sartak)
599 - load_class now returns the metaclass instance
600 instead of just 1 (sartak)
603 - better error messages (sartak and Dave Rolsky)
605 0.62 Wed June 18, 2008
606 - in is_class_loaded, recognize scalar references (as opposed to globs) in
607 the symbol table as methods (these are optimized constant subs)
609 0.61 Fri. June 13, 2008
610 - Okay, lets give this another try and see if PAUSE
611 recognizes it correct this time.
613 0.60 Thurs. Jun 12, 2008
614 - Fixed a version number issue by bumping all modules
617 0.59 Thurs. Jun 12, 2008
618 !! Several fixes resulting in yet another 25-30% speedup !!
621 - now stores the instance of the instance
622 metaclass to avoid needless recomputation
623 and deletes it when the cache is blown
624 - introduce methods to query Class::MOP::Class for
625 the options used to make it immutable as well as
626 the proper immutable transformer. (groditi)
628 * Class::MOP::Package
629 - {add, has, get, remove}_package_symbol all
630 now accept a HASH ref argument as well as the
631 string. All internal usages now use the HASH
635 - MOP.xs does sanity checks on the coderef
637 - is_class_loaded check now uses code that
638 was improved in Moose's ClassName type
640 - nonsensical (undef, empty, reference) class
641 names now throw a more direct error in
643 - tests for this and other aspects of
649 Class::MOP::Method::Wrapped
650 Class::MOP::Attribute
651 - switched usage of reftype to ref because
654 0.58 Thurs. May 29, 2008
655 (late night release engineering)--
657 - fixing the version is META.yml, no functional
658 changes in this release
660 0.57 Wed. May 28, 2008
661 !! Several speedups resulting in 20-25% speedups !!
662 || (thanks to konobi, groditi, mst & CataMoose) !!
665 - made get_method_map use list_all_package_symbols
666 instead of manually grabbing each symbol
667 - streamlining &initialize somewhat, since it gets
670 * Class::MOP::Package
671 - made {get, has}_package_symbol not call
673 - inlining a few calls to &name with
674 direct HASH access key access
675 - added get_all_package_symbols to fetch
676 a HASH of items based on a type filter
677 similar to list_all_package_symbols
678 - added tests for this
681 Class::MOP::Method::Constructor
682 Class::MOP::Method::Generated
683 Class::MOP::Method::Accessor
684 - added more descriptive error message to help
685 keep people from wasting time tracking an error
686 that is easily fixed by upgrading.
688 * Class::MOP::Immutable
689 - Don't inline a destructor unless the user actually
691 - added tests for this
693 0.56 Saturday, May 24, 2008
695 - we now get the &check_package_cache_flag
696 function from MRO::Compat
697 - All XS based functionality now has a
698 Pure Perl alternative
699 - the CLASS_MOP_NO_XS environment variable
700 can now be used to force non-XS versions
703 * Class::MOP::Attribute
704 - add has_read_method and has_write_method
705 - get_{read,write}_method_ref now wraps the
706 anon-sub ref in the method metaclass when
708 - added tests for this
710 * Class::MOP::Immutable
711 - added the ability to "wrap" methods when
712 making the class immutable
715 - now handling the edge case of ->meta->identifier
716 dying by wrapping add_package_symbol to specifically
717 allow for it to work.
718 - added tests for this
720 * Class::MOP::Attribute
722 Class::MOP::Immutable
723 - any time a method meta object is constructed
724 we make sure to pass the correct package and
725 method name information
728 Class::MOP::Method::Wrapped
729 Class::MOP::Method::Generated
730 Class::MOP::Method::Accessor
731 Class::MOP::Method::Consructor
732 - the &wrap constructor method now requires that a
733 'package_name' and 'name' attribute are passed. This
734 is to help support the no-XS version, and will
735 throw an error if these are not supplied.
736 - all these classes are now bootstrapped properly
737 and now store the package_name and name attributes
740 ~ Build.PL has been removed since the
741 Module::Install support has been removed
743 0.55 Mon. April 28, 2008
744 - All classes now have proper C3 MRO support
745 - added MRO::Compat as a dependency to allow
746 for the C3 MRO support to Just Work in all
750 - rebless_instance now returns the instance
751 it has just blessed, this is mostly to
753 - set the attr correctly in rebless_instance
754 when it has no init_arg
755 - tweaked &linear_isa and &class_precedence_list
756 to support c3 classes.
758 0.54 Fri. March, 14, 2008
761 - making sure that load_class never gets
762 passed a value from @_ or $_ to squash
763 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
766 - make_{immutable,mutable} now return 1
768 - improved error handling in ->create method
769 - rebless_instance now takes extra params which
770 will be used to populate values
771 - added tests for this
774 - localizing the Data::Dumper configurations so
775 that it does not pollute others (RT #33509)
781 Class::MOP::Attribute
782 - these classes no longer define their own ->meta,
783 but instead just inherit from Class::MOP::Object
785 * Class::MOP::Instance
786 Class::MOP::Immutable
787 - these classes now inherit from Class::MOP::Object
790 - fixed the filename length on several
791 test files so we install on VMS better
793 - fixed incorrect use of catdir when it
794 should be catfile (RT #32385)

797 ~~ several doc. fixes and updates ~~
800 Class::MOP::Method::Constructor
801 Class::MOP::Attribute
802 - making init_arg accept an undefined value
803 to indicate that no constructor args can
804 be passed (thanks to nothingmuch)
805 - added tests for this
806 - added attribute initializer attribute (rjbs)
809 - making this use the new init_arg => undef
810 feature instead of the silly hack from
811 before (thanks to nothingmuch)
813 0.52 Tues. Jan. 22, 2008
815 - fixed bug in rebless_instance
818 * Class::MOP::Method::Constructor
819 - removed assumptions about the existence of
822 0.51 Mon. Jan. 14, 2008
823 ~~~ some misc. doc. fixes ~~~
824 ~~ updated copyright dates ~~
827 - now sets the IS_RUNNING_ON_5_10
828 constant so that we can take advantage
829 of some of the nice bits of 5.10
832 - uses the IS_RUNNING_ON_5_10 flag to
833 optimize the &linearized_isa method
834 and avoid the hack/check for circular
835 inheritence in &class_precedence_list
836 - added rebless_instance method (Sartak)
837 - added tests for this
839 * Class::MOP::Immutable
840 - the immutable class now keeps track of
841 the transformer which immutablized it

854 * Class::MOP::Immutable
855 - fixed a bug (see above)
857 * Class::MOP::Attribute
860 0.49 Fri. Dec. 14, 2007
861 !! Class::MOP now loads 2 x faster !!
862 !! with XS speedups (thanks konobi) !!
865 - removed the dependency on B
866 - added two XS functions (thanks konobi)
867 - get_code_info($code) which replaces all
868 the B fiddling we were doing with
869 faster/leaner XS level fiddling
870 - check_package_cache_flag($pkg_name) which
871 returns the PL_sub_generation variable to
872 be used to help manage method caching.
875 In 5.10 or greater this will actually
876 use the mro::get_pkg_gen instead to give
877 even more accurate caching information.
878 blblack++ for that stuff :)
881 - added the &subclasses method (thanks rlb)
882 - added the update_package_cache_flag and
883 reset_package_cache_flag which help keep
884 track of when we need to re-fetch the
886 - Several small improvements to take advantage
887 of the new method map caching features
889 0.48 Mon. Nov. 26, 2007
890 * Class::MOP::Attribute
891 - fixed get_read/write_method to handle the

899 - added more tests for this
901 0.46 Fri. Nov. 23, 2007
903 - added the linearized_isa method instead of constantly
904 pruning duplicate classes (this will be even more
905 useful in the 5.10-compat version coming soon)
907 * Class::MOP::Attribute
908 - added the get_read_method_ref and get_write_method_ref
909 methods which allow you to retrieve a CODE ref which
910 can always be used to read or write an attribute.
912 0.45 Thurs. Nov. 13, 2007
913 * Class::MOP::Attribute
914 - Fix error message on confess (groditi)
916 0.44 Thurs. Nov. 13, 2007

919 0.43 Thurs. Nov. 13, 2007
921 - Add support for the 'builder' attribute (groditi)
924 - optimise metaclass-already-exists check in

931 - Make predicates check for the existence of a value, not whether
932 it is defined (groditi)
934 * Class::MOP::Instance
935 - Make predicates check for the existence of a value, not whether
936 it is defined (groditi)
938 * Class::MOP::Method::Accessor
939 - made this a subclass of Class::MOP::Method::Generated
940 - removed the relevant attributes
942 * Class::MOP::Method::Constructor
943 - fixed the cached values we had to be more sane
944 - made this a subclass of Class::MOP::Method::Generated
945 - fixed generated constructor so it properly handles
947 - added tests for this
948 - added the option to allow for both inlined and
949 non-inlined constructors.
950 - Update inlined methods for builder and predicate changes (groditi)
952 * Class::MOP::Method::Generated
953 - added this class as an abstract base for the
954 Class::MOP::Method::{Constructor,Accessor} classes
955 - added tests for this
958 - Alter tests (005, 014 020, 021) for new builder addition (groditi)

967 * Class::MOP::Package
968 - alter symbol table handling to deal with 5.8.x and 5.9.x
971 - Get rid of the crappy workaround from 0.40/41
973 0.41 Sun. July 15, 2007
975 Arghh!!! My TODO test didn't work, so I handle
976 it manually now so that people can use this
977 with 5.9.5/bleadperl without issue.
979 0.40 Tues, July 3, 2007
981 ~ marked a test in 003_methods.t as TODO
982 for perl 5.9.5 (this test is irrelvant to
983 the module functioning on 5.9.5 for the most
986 0.39 Mon. June 18, 2007
987 * Class::MOP::Immutable
988 - added make_metaclass_mutable + docs (groditi)
989 - removed unused variable
990 - added create_immutable_transformer
991 necessary for sane overloading of immutable behavior
992 - tests for this (groditi)
995 - Immutability can now be undone,
996 added make_mutable + tests + docs (groditi)
997 - Massive changes to the way Immutable is done
998 for details see comments next to make_immutable
999 This fixes a bug where custom metaclasses broke
1000 when made immutable. We are now keeping one immutable
1001 metaclass instance per metaclass instead of just one
1002 to prevent isa hierarchy corruption. Memory use will go
1003 up, but I suspect it will be neglible.
1004 - New tests added for this behavior. (groditi)
1006 0.38 Thurs. May 31, 2007
1007 ~~ More documentation updates ~~
1009 * Class::MOP::Package

1016 thanks to groditi for this code, tests
1018 - added tests and POD for this
1021 - fixed RT issue #27329, clone object now
1022 handles undef values correctly.
1023 - added tests for this
1024 - Corrected anon-class handling so that they
1025 will not get reaped when instances still
1026 exist which need to reference them. This is
1027 the correct behavior, hopefully this is an
1028 obscure enough feature that there are not too
1029 many work arounds out in the wild.
1030 - added tests for this by groditi
1031 - updated docs to explain this
1034 - load custom metaclasses automatically (thanks groditi)
1035 - added tests for this behavior
1037 0.37 Sat. March 10, 2007

1046 avoid setting off bool-overloads (found by Carl Franks)
1050 - bad name in a test, causing meaningless failuress.
1055 ~~ GLOBAL CHANGES ~~
1056 - All attribute names are now consistent and follow Perl 6
1057 style (prefixed with the sigil, and ! as the twigil for
1058 private attrs). This should not affect any code, unless
1059 you broke encapsulation, in which case, it is your problem
1062 !! Class::MOP::Class::Immutable has been removed
1064 * Class::MOP::Method::Constructor
1065 - this has been moved out of Class::MOP::Class::Immutable
1066 and is a proper subclass of Class::MOP::Method now.
1069 - this module now uses Class::MOP::Immutable for the
1070 immutable transformation instead of
1071 Class::MOP::Class::Immutable.
1073 + Class::MOP::Immutable
1074 - this module now controls the transformation from a mutable
1075 to an immutable version of the class. Docs for this will
1076 be coming eventually.
1079 0.36 Sun. Nov. 5, 2006
1081 - added a few 'no warnings' lines to keep annoying
1082 (and meaningless) warnings from chirping during
1086 - some more bootstrapping is now done on the new
1089 * Class::MOP::Class::Immutable
1091 - constructor generation is now handled by
1092 the Class::MOP::Method::Constructor class
1094 * Class::MOP::Method::Constructor
1095 - created this to handle constructor generation
1096 in Class::MOP::Class::Immutable
1098 * Class::MOP::Attribute
1100 - attributes now delegate to the
1101 Class::MOP::Method::Accessor to generate
1104 * Class::MOP::Method::Accessor

1122 - adjusted tests for this
1123 - added the Class::MOP::Instance attributes

1130 - adjusted tests to compensate
1131 - adjusted docs for this
1134 - changed how methods are dealt with to
1135 encapsulate most of the work into the
1136 &get_method_map method
1137 - made several adjustments for the change
1138 in Class::MOP::Method
1139 - &add_attribute now checks if you are adding
1140 a duplicate name, and properly removes the
1141 old one before installing the new one

1143 - adjusted docs for this
1145 * Class::MOP::Class::Immutable
1146 - added caching of &get_method_map

1152 &list_all_package_symbols
1154 0.34 Sat. Aug. 26, 2006
1156 - added the %:methods attribute, which like
1157 the $:version and such just actually goes
1158 to the symbol table to get it's stuff.
1159 However, it makes the MOP more complete.
1161 - The &create method now requires that all
1162 but the package name now is passed in as
1163 named parameters. See docs for more info.
1164 - updated docs and tests for this
1166 * Class::MOP::Object
1167 - added &dump method to easily Data::Dumper

1190 - added tests for this
1192 * Class::MOP::Package
1193 - fixed an issue with perl 5.8.1 and how it deals
1194 with symbol tables. The namespace hash is now
1195 always reloaded from the symbol table.
1197 ~ lots of misc. documentation cleanup
1199 0.32 Sat. Aug. 12, 2006
1200 + added Class::MOP::Object so that the
1201 metamodel is more complete (and closer
1202 to what Perl 6 will probably be).

1206 the primary gateway between the metaclass
1207 and the Perl 5 symbol table
1208 - added many tests for this

1218 - adding the $:version attribute in the bootstrap
1219 so that Module has a version as an attribute
1220 - see comment in Class::MOP for details
1221 - added the $:authority attribute to this module
1222 as well as an &identifier method, to bring us
1223 ever closer to Perl 6 goodness

1244 - added &set_value and &get_value for getting
1245 the value of the attribute for a particular
1248 0.30 Wed. July 5, 2006
1249 ---------------------------------------
1250 This is the first version of Class::MOP
1251 to introduce the immutable features which
1252 will be used for optimizating the MOP.
1253 This support should still be considered
1254 experimental, but moving towards stability.
1255 ---------------------------------------
1257 * Created Class::MOP::Class::Immutable
1259 * Created the Class::MOP::Package and
1260 Class::MOP::Module classes to more
1261 closely conform to Perl 6's meta-model
1264 - now inherits from Class::MOP::Module
1265 - several methods moved to ::Module and
1266 ::Package and now inherited
1267 - added tests for this
1269 * Class::MOP::Instance
1270 - added an is_inlinable method to allow other
1271 classes to check before they attempt to optimize.
1272 - added an inline_create_instance to inline
1273 instance creation (of course)
1276 - the Class::MOP::Class::*_package_variable
1277 methods are all now methods of Class::MOP::Package
1278 and called *_package_symbol instead. This is
1279 because they are now more general purpose symbol
1280 table manipulation methods.
1282 0.29_02 Thurs. June 22, 2006
1283 ++ DEVELOPER RELEASE ++
1285 - small change in &create so that it behaves

1342 of the attribute itself, and construct_instance now
1343 delegates appropriately
1345 * Class::MOP::Attribute
1346 - attribute slot initialization is now the responsibility
1347 of the attribute itself, so we added a method for it
1348 called initialize_instance_slot

1405 - &add_after_method_modifier
1406 - &add_around_method_modifier
1407 - added tests and docs for these

1426 shallow clone (see docs for more details)
1427 - added docs and tests
1429 0.10 Tues Feb. 14, 2006
1430 ** This release was mostly about writing more tests and
1431 cleaning out old and dusty code, the MOP should now
1432 be considered "ready to use".
1434 - adding more tests to get coverage up a little higher,
1435 mostly testing errors and edge cases.
1436 - test coverage is now at 99%
1439 - no longer optionally exports to UNIVERSAL::meta or

1457 metaclass a little more straightforward
1460 - clean up bootstrapping to include more complete
1461 attribute definitions for Class::MOP::Class and
1462 Class::MOP::Attribute (accessors, readers, writers,
1463 etc.) ... it is redundant, but is useful meta-info
1467 - fixing minor meta-circularity issue with &meta, it
1468 is now more useful for subclasses
1469 - added &get_attribute_map as an accessor for the
1470 hash of attribute meta objects
1471 - &compute_all_applicable_attributes now just returns
1472 the attribute meta-object, rather than the HASH ref
1473 since all the same info can be gotten from the
1474 attribute meta-object itself
1475 - updated docs & tests to reflect
1476 - added &clone_instance method which does a deep clone
1477 of the instance structure created by &construct_instance
1478 - added docs & tests for this
1479 - added Clone as a dependency
1480 - added &new_object and &clone_object convience methods to
1481 return blessed new or cloned instances
1482 - they handle Class::MOP::Class singletons correctly too
1483 - added docs & tests for this
1484 - cleaned up the &constuct_class_instance so that it behaves
1485 more like &construct_instance (and managed the singletons too)
1486 - added the &check_metaclass_compatibility method to make sure
1487 that metaclasses are upward and downward compatible.
1488 - added tests and docs for this
1491 - adjusting code to use the &Class::MOP::Class::meta
1493 - adjusting code to use the metaclass pragma
1495 0.05 Sat Feb. 4, 2006
1497 - added the &attribute_metaclass and &method_metaclass
1498 attributes which contain a metaclass name to use for
1499 attributes/methods respectively
1502 - bootstrap additional attributes for Class::MOP::Class
1505 - adjusted the example code and tests to use the new
1506 &attribute_metaclass feature of Class::MOP::Class
1507 - added new example:
1510 0.04 Fri Feb. 3, 2006
1512 - some documentation suggestions from #perl6
1514 * Class::MOP::Attribute
1515 - improved error messages
1518 - added new examples:
1519 - AttributesWithHistory
1520 - ClassEncapsultedAttributes
1522 0.03 Fri Feb. 3, 2006
1523 - converted to Module::Build instead of EU::MM
1525 * Class::MOP::Attribute
1526 - refactored method generation code
1527 - attributes are now associated with class directly
1530 - refactored the InsideOut example to take advantage
1531 of the Class::MOP::Attribute refactoring
1532 - changed example files to .pod files and hide thier
1533 package names from PAUSE (I don't want to own these
1534 namespaces really, they are just examples)
1536 0.02 Thurs Feb. 2, 2006
1537 - moving examples from t/lib/* to examples/*
