1 Revision history for Perl extension Class-MOP.
5 - Made sure to always local-ize $@ and $SIG{__DIE__} before
6 calling an eval. Fixes RT #45973.
9 - Synced docs about immutability with the current reality (which
10 changed back in 0.82_01)
11 - Removed the immutable_transformer method, which had been
12 returning undef since 0.82_01 anyway.
15 - Got rid of tests which needed Moose and improved testing of
16 constructor/destructor inlining warnings. Fixes RT #47119.
18 0.86 Tue, Jun 16, 2009
20 - If you redefined a subroutine at runtime and then wrapped it
21 with a method modifier, the modifier could in some cases wrap
22 the original version of the subroutine. Fixes RT #46957.
25 - make_immutable issues a warning instead of overriding an
26 existing DESTROY method (Dylan William Hardison). Fixes RT
30 * Class::MOP::Attribute
31 - Allow default values to be Class::MOP::Methods. (Florian
33 - Test the above. (Rhesa Rozendaal)
34 - Tweak original commit so the intent matches the accepted
35 behavior (Nicholas Perez)
38 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
41 - Add direct_subclasses method (Sartak)
42 - Tests for subclasses and direct_subclasses (Sartak)
43 - subname is no longer used unconditionally in add_method, but
44 only if the code reference's name is '__ANON__' (nothingmuch)
45 - Add a hook for _superclasses_updated (Sartak)
48 - Remove long, old warning about possibly outdated modules
51 0.84 Tue, May 12, 2009
53 - Depend on Text::Exception 0.27 to avoid failing tests ond old
57 - Made is_class_loaded a little stricter. It was reporting that
58 a class was loaded if it merely had an @ISA variable in its
59 stash. Now it checks that the @ISA var has elements in it.
60 - Deprecate in_global_destruction and subname re-exporting
64 - Explicitly use Devel::GlobalDestruction and Sub::Name
68 - Disable prototype mismatch warnings for add_package_symbol.
71 0.83 Mon, April 27, 2009
73 - Fix segfault when calling get_method_map on a metaclass for an empty
76 0.82_02 Fri, April 24, 2009
77 * Class::MOP::Method::Inlined
78 - Don't inline if the expected method is not defined at all (happens with
79 e.g. Moose::Object::_new is the expected method due to an overridden
82 - Some tests were trying to load Class::MOP::Immutable, which
83 was removed in 0.82_01.
85 0.82_01 Thu, April 23, 2009
86 * Class::MOP::Immutable (and others)
87 - Refactor the immutability system to use a pre-defined class
88 for the immutable metaclass of Class::MOP::Class::Immutable::$class
89 - Rather than generating methods into this class every time, use
90 a Trait (basic mixin) to supply the cached methods
91 - Remove the hack that returns the mutable metaclass for
92 metacircularity in order to provide consistent meta-metaclasses
93 for the Moose compatibility handling code
94 (mst broke it, nothingmuch fixed it)
96 0.82 Mon, April 20, 2009
98 - The deprecation wrappers for some renamed methods were not
99 passing arguments to the new method. (nothingmuch)
101 * Class::MOP::Immutable
102 - Warn during immutablization if the local class provides its own
103 constructor, to parallel the warning in Moose when a superclass
104 provides its own constructor (doy)
106 0.81 Tue, April 7, 2009
109 * Class::MOP::Instance
110 * Class::MOP::Attribute
111 * Class::MOP::Method::Accessor
112 * Class::MOP::Method::Constructor
113 - Include stack traces in the deprecation warnings introduced in
114 0.80_01. (Florian Ragwitz)
117 - Avoid c compiler warnings by declaring some unused function
118 arguments. (Florian Ragwitz)
120 0.80_01 Sun, April 5, 2009
122 - Make sure to preserve any compiler flags already defined in
123 Config.pm. Patch by Vincent Pit. RT #44739.
125 * Many methods have been renamed with a leading underscore, and a
126 few have been deprecated entirely. The methods with a leading
127 underscore are consider "internals only". People writing
128 subclasses or extensions to Class::MOP should feel free to
129 override them, but they are not for "public" use.
132 - construct_class_instance => _construct_class_instance (use new_object)
133 - construct_instance => _construct_instance (use new_object)
134 - check_metaclass_compatibility => _check_metaclass_compatibility
135 - create_meta_instance => _create_meta_instance (use get_meta_instance)
136 - clone_instance => _clone_instance (use clone_object)
137 - compute_all_applicable_methods is deprecated, use get_all_methods
138 - compute_all_applicable_attributes is deprecated, use get_all_attributes
140 - Class::MOP::Instance
141 - bless_instance_structure is deprecated and will be removed
145 - create has been renamed to _instantiate_module. This method
146 does not construct an object, it evals some code that
147 creates the relevant package in Perl's symbol table.
149 - Class::MOP::Method::Accessor
150 - initialize_body => _initialize_body (this is always called
151 when an object is constructed)
152 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
154 - Class::MOP::Method::Constructor
155 - initialize_body => _initialize_body (this is always called
156 when an object is constructed)
157 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
158 - attributes => _attributes
159 - meta_instance => _meta_instance
161 0.80 Wed, April 1, 2009
163 - Call user_class->meta in fewer places, with the eventual goal
164 of allowing the user to rename or exclude ->meta
165 altogether. Instead uses Class::MOP::class_of. (Sartak)
168 - New class_of function that should be used to retrieve a
169 metaclass. This is unlike get_metaclass_by_name in that it
170 accepts instances, not just class names. (Sartak)
173 - load_first_existing_class didn't actually load the first
174 existing class; instead, it loaded the first existing and
175 compiling class. It now throws an error if a class exists (in
176 @INC) but fails to compile. (hdp)
180 - we had some semi-buggy code that purported to provide a
181 HAS_ISAREV based on whether mro had get_isarev (due to an
182 oversight, it always returned 1). Since mro and MRO::Compat
183 have always had get_isarev, HAS_ISAREV was pointless. This
184 insight simplified the subclasses method by deleting the
185 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
187 0.79 Fri, March 29, 2009
188 * No changes from 0.78_02.
190 0.78_02 Thu, March 26, 2009
192 * Class::MOP::Immutable
193 - A big backwards-incompatible refactoring of the Immutable API,
194 and the make_immutable/make_mutable pieces of the Class
195 API. The core __PACKAGE__->meta->make_immutable API remains
196 the same, however, so this should only affect the most
200 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
201 has been fixed to be backwards compatible with 5.8.x.
204 - Add a hook for rebless_instance_away (Sartak)
205 - Use blessed instead of ref to get an instance's class name
206 in rebless_instance. (Sartak)
208 0.78_01 Wed, March 18, 2009
210 - Revised and reorganized all of the API documentation. All
211 classes now have (more or less) complete API documentation.
214 * Class::MOP::Instance
215 - Reblessing into a package that supports overloading wasn't
216 properly adding overload magic to the object due to a bug
217 in (at least) 5.8.8. We now use $_[1] directly which seems
218 to set the magic properly. (Sartak)
220 * Class::MOP::Attribute
221 - The process_accessors method is now private. A public alias
222 exists (and will stick around for a few releases), but it
223 warns that calling the public method is deprecated.
225 * Class::MOP::Method::Generated
226 - Removed the new and _new methods, since this is an abstract
227 base class, and all existing subclasses implement their own
231 - Stop is_class_loaded from thinking a class is loaded if it
232 only has an empty GV (Florian Ragwitz).
233 - Add a test for this (Yappo).
234 - Refactor get_all_package_symbols to allow short-circuiting
236 - Use this in is_class_loaded (Florian Ragwitz).
237 - Stop segfaulting when trying to get the name from a sub that's
238 still being compiled (Florian Ragwitz).
239 - Add tests for this (Florian Ragwitz).
240 - Prefix all public symbols with "mop_" (Florian Ragwitz).
241 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
242 - Simplify creating simple xs reader methods (Florian Ragwitz).
243 - Make everything compile with c++ compilers (Florian Ragwitz).
244 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
247 - Remove optional test plans for tests depending on Sub::Name as
248 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
251 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
253 0.78 Mon, February 23, 2009
254 * No changes from 0.77_01
256 0.77_01 Sun, February 22, 2009
258 - This package now requires its XS components. Not using
259 Sub::Name lead to different behavior and bugginess in the pure
260 Perl version of the code. A Moose test would fail when run
261 against the pure Perl version of this code.
263 * Class::MOP::Instance
264 - The inline_* methods now quote attribute names themselves, and
265 don't expect to receive a quoted value.
268 0.77 Sat, February 14, 2009
270 - Avoid assertion errors on debugging perls in is_class_loaded
274 - Fixed various corner cases where is_class_loaded incorrectly
275 returned true for a class that wasn't really loaded. (Dave
279 - Add get_all_method_names (Sartak)
280 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
282 * Class::MOP::Package
283 - Disable deprecated get_all_package_symbols in list
284 context. (Florian Ragwitz)
287 - Make sure we generate a BSD-compatible Makefile (Florian
291 - The misspelled "check_metaclass_compatability" method we've
292 kept around for backwards compat_i_bility will be removed in a
293 near future release. You've been warned.
295 0.76 Thu, January 22, 2009
296 * Class::MOP::Method::Generated
297 - Added new private methods to support code generation, which
298 are being used by Moose and can be used by MooseX
300 - Generated methods are now generated with a #line directive
301 reflecting the source of the generated method. (nothingmuch)
304 - Clarified documentation of methods that return
305 Class::MOP::Method objects. (doy)
308 - Clarified documentation of the metaclass cache methods. (Sartak)
311 - Add test showing how the xs Class::MOP::is_class_loaded can
312 be made to operate differently to the pure perl version (t0m)
314 0.75 Wed, December 31, 2008
316 - A class that was made immutable and then mutable could end up
317 sharing an immutable transformer object
318 (Class::MOP::Immutable) with other classes, leading to all
319 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
321 0.74 Tue, December 25, 2008
323 - Add an xs implementation of Class::MOP::is_class_loaded (closes
324 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
325 - Changed internals to make prehashing of hash keys easier and less
326 error-prone. (Florian Ragwitz)
328 - Fix documentation to show that around modifiers happen on both
329 sides of the modified method. (Dave Rolsky)
331 0.73 Tue, December 16, 2008
333 - Don't use Perl_mro_meta_init. It's not part of the public perl
334 api. Fixes failures to build on Win32 (RT #41750). (Florian
336 * t/082_get_code_info.t
337 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
338 munger anonymous subs when under -d and so making the tests
339 succeed in that case.
341 0.72 Mon, December 8, 2008
342 * Class::MOP::Package
343 - Pass options to _new, so subclass' attributes can be
346 - In the docs, indicate that package_name and name are required
347 when calling ->wrap (Stefan O'Rear)
349 0.71_02 Fri, December 5, 2008
350 * Class::MOP::Immutable
351 - Added a new attribute, inlined_constructor, which is true if
352 the constructor was inlined.
353 * Class::MOP::Package
354 - Make get_all_package_symbols return a hash ref in scalar
355 context and deprecate calling it in list context with a
356 warning. (Florian Ragwitz)
358 - Various improvements and refactoring, making things more robust and
359 easier to maintain. (Florian Ragwitz)
361 0.71_01 Wed, December 3, 2008
363 - Add an "execute" method to invoke the body so
364 we can avoid using the coderef overload (Sartak)
365 * Class::MOP::Immutable
366 - When we memoize methods, get their results lazily
367 to remove some compile-time cost (Sartak)
368 - Small speedup from eliminating several method
371 - Some small internal tweaks to try to reduce the number of
372 times we call get_method_map when bootstrapping the MOP. This
373 might make loading Class::MOP (and Moose) a little
374 faster. (Dave Rolsky)
375 - Implemented an optional XS version of get_method_map. Mostly
376 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
377 help form Florian Ragwitz. (Dave Rolsky)
378 - Make the behaviour of of get_all_package_symbols (and
379 therefore get_method_map) consistent for stub methods. Report
380 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
382 0.71 Wed November 26, 2008
385 - Actual package creation has moved upward from
386 Class to Module so that Moose roles can share
389 0.70_01 Mon, November 19, 2008
391 - Fixes for failures with blead (Florian Ragwitz)
392 - Silenced compiler warnings (Florian Ragwitz)
394 0.70 Fri, November 14, 2008
396 - Fixed an odd corner case where the XS version of
397 get_all_package_symbols could cause a segfault. This only
398 happened with inlined constants in Perl 5.10.0 (Florian
401 0.69 Fri, November 7, 2008
402 * Class::MOP::Method::Wrapped
403 - Added introspection methods for method modifiers (Dave Rolsky)
406 0.68 Fri October 24, 2008
408 - Make load_class require by file name instead of module name.
409 This stops confusing error messages when loading '__PACKAGE__'.
411 - Add load_one_class_of function to enable you to load one of a
412 list of classes, rather than having to call load_class multiple
413 times in an eval. (t0m)
415 0.67 Tue October 14, 2008
417 - Call a method on the class after setting the superclass list
418 so that we can get Perl to detect cycles before MRO::Compat
419 spirals into an infinite loop (sartak)
420 - Reported by Schwern, [rt.cpan.org #39001]
421 - In create(), pass unused options on to initialize()
422 - added test for this
424 0.66 Sat September 20, 2008
425 !! This release has an incompatible change regarding !!
426 introspection of a class's method with Class::MOP::Class !!
429 - We (us maintainers) now run all tests with XS and then without
430 XS, which should help us catch skew between the XS/pure Perl
434 ! The alias_method method has been deprecated. It now simply
435 calls add_method instead. There is no distinction between
436 aliased methods and "real" methods.
438 This means that methods added via alias_method now show up as
439 part of the class's method list/map. This is a backwards
440 incompatible change, but seems unlikely to break any
441 code. Famous last words. (Dave Rolsky)
444 - Fixed the spelling of "compatibility", but we still have a
445 "check_metaclass_compatability" method for backwards
448 0.65 Mon September 1, 2008
449 For those not following the series of dev releases, the changes
450 from 0.64 from 0.65 can mostly be summed up as a lot performance
451 improvements by nothingmuch, including new optional XS versions of
452 some methods. Also, Class::MOP now works _without_ any XS modules,
453 for sad systems without a compiler.
456 - Added name and package_name XS accessors, and make sure all
457 the XS and Perl versions work the same way. (Dave Rolsky)
460 - The XS versions of various methods just returned undef when
461 called class methods, rather than dying like the pure Perl
462 versions. (Dave Rolsky)
464 0.64_07 Fri August 29, 2008
466 - Silenced warnings that managed to break Moose tests when XS
467 was loaded. (Dave Rolsky)
468 - Some XS versions of methods were ignored because of typos in
469 MOP.xs. (Dave Rolsky)
471 0.64_06 Mon August 25, 2008
472 * Class::MOP (MOP.xs)
473 - Another MS VC++ fix, cannot declare a variable in the middle
474 of a scope (Taro Nishino).
476 0.64_05 Sun August 24, 2008
478 - None of the dev releases actually loaded the XS properly, but
479 we silently fell back to the pure Perl version of the
482 * Class::MOP (MOP.xs)
483 - Replaced some code that used functions not available on Visual
484 C++ with some Perl XS API bits (Dave Rolsky).
486 0.64_04 Sat August 23, 2008
488 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
490 * pod.t and pod_coveraget.t
491 - These are no longer shipped with the tarball because of bogus
492 failures from CPAN testers. (Dave Rolsky)
494 0.64_03 Thu August 21, 2008
495 * Class::MOP::Package
496 - Some (legit) code was misparsed by earlier 5.8.x
497 releases. (nothingmuch)
500 - Fix a constant in void context warning (nothingmuch)
502 0.64_02 Thu August 21, 2008
503 * Makefile.PL and Class::MOP
504 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
507 - Add missing prereqs that got lost in the switch away from
510 * Class::MOP::Instance
511 - New method - get_all_attributes (nothingmuch)
513 0.64_01 Wed August 20, 2008
515 - We now check to see if you have a compiler. If you don't, the
516 module installs without some XS bits, but will work the same
517 as with XS. This should make it easier to install on platforms
518 without a compiler (like Windows). (Dave Rolsky)
521 - Perl 6 style attribute naming replaced with sane style ('methods', not
522 '%!methods'). These changes should not impact any existing API uses.
526 - Quite a number of optimizations based on profiling, including
527 allowing constructors to take hash references instead of
528 hashes, duplicating some frequently used code in XS, and
529 making constructors immutable. These changes should not impact
530 any existing API uses. (nothingmuch)
533 - Constructors now respect the meta attributes of their subclasses,
534 facilitating MOP extensibility. More related changes will happen in the
535 next several releases. (nothingmuch)
538 - New method - get_all_methods, replaces the deprecated
539 compute_all_applicable_methods. get_all_attributes provided for
540 consistency (nothingmuch)
541 - New method - wrap_method was refactored out of get_method_map
543 - New API for meta instance invalidation - invalidate_meta_instance,
544 invalidate_meta_instances, add_dependent_meta_instance,
545 remove_dependent_meta_instance, called automatically when attribute
546 definitions change and allows notification of dependent subclasses.
549 0.64 Sun August 3, 2008
550 * Class::MOP::Immutable
551 - fixing subtle edge case in immutable when you
553 - clean up option processing (nothingmuch)
555 * Class::MOP::Instance
556 - inlined initialize slot didn't match
557 non-inlined (nothingmuch)
559 0.63 Mon July 7, 2008
561 - load_class will initialize a metaclass even if
562 the class is already loaded (sartak)
563 - load_class now returns the metaclass instance
564 instead of just 1 (sartak)
567 - better error messages (sartak and Dave Rolsky)
569 0.62 Wed June 18, 2008
570 - in is_class_loaded, recognize scalar references (as opposed to globs) in
571 the symbol table as methods (these are optimized constant subs)
573 0.61 Fri. June 13, 2008
574 - Okay, lets give this another try and see if PAUSE
575 recognizes it correct this time.
577 0.60 Thurs. Jun 12, 2008
578 - Fixed a version number issue by bumping all modules
581 0.59 Thurs. Jun 12, 2008
582 !! Several fixes resulting in yet another 25-30% speedup !!
585 - now stores the instance of the instance
586 metaclass to avoid needless recomputation
587 and deletes it when the cache is blown
588 - introduce methods to query Class::MOP::Class for
589 the options used to make it immutable as well as
590 the proper immutable transformer. (groditi)
592 * Class::MOP::Package
593 - {add, has, get, remove}_package_symbol all
594 now accept a HASH ref argument as well as the
595 string. All internal usages now use the HASH
599 - MOP.xs does sanity checks on the coderef
601 - is_class_loaded check now uses code that
602 was improved in Moose's ClassName type
604 - nonsensical (undef, empty, reference) class
605 names now throw a more direct error in
607 - tests for this and other aspects of
613 Class::MOP::Method::Wrapped
614 Class::MOP::Attribute
615 - switched usage of reftype to ref because
618 0.58 Thurs. May 29, 2008
619 (late night release engineering)--
621 - fixing the version is META.yml, no functional
622 changes in this release
624 0.57 Wed. May 28, 2008
625 !! Several speedups resulting in 20-25% speedups !!
626 || (thanks to konobi, groditi, mst & CataMoose) !!
629 - made get_method_map use list_all_package_symbols
630 instead of manually grabbing each symbol
631 - streamlining &initialize somewhat, since it gets
634 * Class::MOP::Package
635 - made {get, has}_package_symbol not call
637 - inlining a few calls to &name with
638 direct HASH access key access
639 - added get_all_package_symbols to fetch
640 a HASH of items based on a type filter
641 similar to list_all_package_symbols
642 - added tests for this
645 Class::MOP::Method::Constructor
646 Class::MOP::Method::Generated
647 Class::MOP::Method::Accessor
648 - added more descriptive error message to help
649 keep people from wasting time tracking an error
650 that is easily fixed by upgrading.
652 * Class::MOP::Immutable
653 - Don't inline a destructor unless the user actually
655 - added tests for this
657 0.56 Saturday, May 24, 2008
659 - we now get the &check_package_cache_flag
660 function from MRO::Compat
661 - All XS based functionality now has a
662 Pure Perl alternative
663 - the CLASS_MOP_NO_XS environment variable
664 can now be used to force non-XS versions
667 * Class::MOP::Attribute
668 - add has_read_method and has_write_method
669 - get_{read,write}_method_ref now wraps the
670 anon-sub ref in the method metaclass when
672 - added tests for this
674 * Class::MOP::Immutable
675 - added the ability to "wrap" methods when
676 making the class immutable
679 - now handling the edge case of ->meta->identifier
680 dying by wrapping add_package_symbol to specifically
681 allow for it to work.
682 - added tests for this
684 * Class::MOP::Attribute
686 Class::MOP::Immutable
687 - any time a method meta object is constructed
688 we make sure to pass the correct package and
689 method name information
692 Class::MOP::Method::Wrapped
693 Class::MOP::Method::Generated
694 Class::MOP::Method::Accessor
695 Class::MOP::Method::Consructor
696 - the &wrap constructor method now requires that a
697 'package_name' and 'name' attribute are passed. This
698 is to help support the no-XS version, and will
699 throw an error if these are not supplied.
700 - all these classes are now bootstrapped properly
701 and now store the package_name and name attributes
704 ~ Build.PL has been removed since the
705 Module::Install support has been removed
707 0.55 Mon. April 28, 2008
708 - All classes now have proper C3 MRO support
709 - added MRO::Compat as a dependency to allow
710 for the C3 MRO support to Just Work in all
714 - rebless_instance now returns the instance
715 it has just blessed, this is mostly to
717 - set the attr correctly in rebless_instance
718 when it has no init_arg
719 - tweaked &linear_isa and &class_precedence_list
720 to support c3 classes.
722 0.54 Fri. March, 14, 2008
725 - making sure that load_class never gets
726 passed a value from @_ or $_ to squash
727 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
730 - make_{immutable,mutable} now return 1
732 - improved error handling in ->create method
733 - rebless_instance now takes extra params which
734 will be used to populate values
735 - added tests for this
738 - localizing the Data::Dumper configurations so
739 that it does not pollute others (RT #33509)
745 Class::MOP::Attribute
746 - these classes no longer define their own ->meta,
747 but instead just inherit from Class::MOP::Object
749 * Class::MOP::Instance
750 Class::MOP::Immutable
751 - these classes now inherit from Class::MOP::Object
754 - fixed the filename length on several
755 test files so we install on VMS better
757 - fixed incorrect use of catdir when it
758 should be catfile (RT #32385)

761 ~~ several doc. fixes and updates ~~
764 Class::MOP::Method::Constructor
765 Class::MOP::Attribute
766 - making init_arg accept an undefined value
767 to indicate that no constructor args can
768 be passed (thanks to nothingmuch)
769 - added tests for this
770 - added attribute initializer attribute (rjbs)
773 - making this use the new init_arg => undef
774 feature instead of the silly hack from
775 before (thanks to nothingmuch)
777 0.52 Tues. Jan. 22, 2008
779 - fixed bug in rebless_instance
782 * Class::MOP::Method::Constructor
783 - removed assumptions about the existence of
786 0.51 Mon. Jan. 14, 2008
787 ~~~ some misc. doc. fixes ~~~
788 ~~ updated copyright dates ~~
791 - now sets the IS_RUNNING_ON_5_10
792 constant so that we can take advantage
793 of some of the nice bits of 5.10
796 - uses the IS_RUNNING_ON_5_10 flag to
797 optimize the &linearized_isa method
798 and avoid the hack/check for circular
799 inheritence in &class_precedence_list
800 - added rebless_instance method (Sartak)
801 - added tests for this
803 * Class::MOP::Immutable
804 - the immutable class now keeps track of

821 * Class::MOP::Attribute
824 0.49 Fri. Dec. 14, 2007
825 !! Class::MOP now loads 2 x faster !!
826 !! with XS speedups (thanks konobi) !!
829 - removed the dependency on B
830 - added two XS functions (thanks konobi)
831 - get_code_info($code) which replaces all
832 the B fiddling we were doing with
833 faster/leaner XS level fiddling
834 - check_package_cache_flag($pkg_name) which
835 returns the PL_sub_generation variable to
836 be used to help manage method caching.
839 In 5.10 or greater this will actually
840 use the mro::get_pkg_gen instead to give
841 even more accurate caching information.
842 blblack++ for that stuff :)
845 - added the &subclasses method (thanks rlb)
846 - added the update_package_cache_flag and
847 reset_package_cache_flag which help keep
848 track of when we need to re-fetch the
850 - Several small improvements to take advantage
851 of the new method map caching features
853 0.48 Mon. Nov. 26, 2007
854 * Class::MOP::Attribute
855 - fixed get_read/write_method to handle the

865 0.46 Fri. Nov. 23, 2007
867 - added the linearized_isa method instead of constantly
868 pruning duplicate classes (this will be even more
869 useful in the 5.10-compat version coming soon)
871 * Class::MOP::Attribute
872 - added the get_read_method_ref and get_write_method_ref
873 methods which allow you to retrieve a CODE ref which
874 can always be used to read or write an attribute.
876 0.45 Thurs. Nov. 13, 2007
877 * Class::MOP::Attribute
878 - Fix error message on confess (groditi)
880 0.44 Thurs. Nov. 13, 2007
881 - Apparently I didn't make dist correctly (groditi)
883 0.43 Thurs. Nov. 13, 2007
885 - Add support for the 'builder' attribute (groditi)
888 - optimise metaclass-already-exists check in
889 construct_class_instance (groditi)

891 call through (groditi)
893 * Class::MOP::Attribute
894 - Add support for the 'builder' attribute (groditi)
895 - Make predicates check for the existence of a value, not whether
896 it is defined (groditi)
898 * Class::MOP::Instance
899 - Make predicates check for the existence of a value, not whether
900 it is defined (groditi)
902 * Class::MOP::Method::Accessor
903 - made this a subclass of Class::MOP::Method::Generated
904 - removed the relevant attributes
906 * Class::MOP::Method::Constructor
907 - fixed the cached values we had to be more sane
908 - made this a subclass of Class::MOP::Method::Generated
909 - fixed generated constructor so it properly handles
911 - added tests for this
912 - added the option to allow for both inlined and
913 non-inlined constructors.
914 - Update inlined methods for builder and predicate changes (groditi)
916 * Class::MOP::Method::Generated
917 - added this class as an abstract base for the
918 Class::MOP::Method::{Constructor,Accessor} classes

932 - alter symbol table handling to deal with 5.8.x and 5.9.x
935 - Get rid of the crappy workaround from 0.40/41
937 0.41 Sun. July 15, 2007
939 Arghh!!! My TODO test didn't work, so I handle
940 it manually now so that people can use this
941 with 5.9.5/bleadperl without issue.
943 0.40 Tues, July 3, 2007
945 ~ marked a test in 003_methods.t as TODO
946 for perl 5.9.5 (this test is irrelvant to
947 the module functioning on 5.9.5 for the most
950 0.39 Mon. June 18, 2007
951 * Class::MOP::Immutable
952 - added make_metaclass_mutable + docs (groditi)
953 - removed unused variable
954 - added create_immutable_transformer
955 necessary for sane overloading of immutable behavior
956 - tests for this (groditi)
959 - Immutability can now be undone,
960 added make_mutable + tests + docs (groditi)
961 - Massive changes to the way Immutable is done
962 for details see comments next to make_immutable
963 This fixes a bug where custom metaclasses broke
964 when made immutable. We are now keeping one immutable
965 metaclass instance per metaclass instead of just one
966 to prevent isa hierarchy corruption. Memory use will go
967 up, but I suspect it will be neglible.
968 - New tests added for this behavior. (groditi)
970 0.38 Thurs. May 31, 2007
971 ~~ More documentation updates ~~
973 * Class::MOP::Package

980 thanks to groditi for this code, tests
982 - added tests and POD for this
985 - fixed RT issue #27329, clone object now
986 handles undef values correctly.
987 - added tests for this
988 - Corrected anon-class handling so that they
989 will not get reaped when instances still
990 exist which need to reference them. This is
991 the correct behavior, hopefully this is an
992 obscure enough feature that there are not too
993 many work arounds out in the wild.
994 - added tests for this by groditi
995 - updated docs to explain this
998 - load custom metaclasses automatically (thanks groditi)
999 - added tests for this behavior
1001 0.37 Sat. March 10, 2007

1010 avoid setting off bool-overloads (found by Carl Franks)
1014 - bad name in a test, causing meaningless failuress.
1019 ~~ GLOBAL CHANGES ~~
1020 - All attribute names are now consistent and follow Perl 6
1021 style (prefixed with the sigil, and ! as the twigil for
1022 private attrs). This should not affect any code, unless
1023 you broke encapsulation, in which case, it is your problem
1026 !! Class::MOP::Class::Immutable has been removed
1028 * Class::MOP::Method::Constructor
1029 - this has been moved out of Class::MOP::Class::Immutable
1030 and is a proper subclass of Class::MOP::Method now.
1033 - this module now uses Class::MOP::Immutable for the
1034 immutable transformation instead of
1035 Class::MOP::Class::Immutable.
1037 + Class::MOP::Immutable
1038 - this module now controls the transformation from a mutable
1039 to an immutable version of the class. Docs for this will
1040 be coming eventually.
1043 0.36 Sun. Nov. 5, 2006
1045 - added a few 'no warnings' lines to keep annoying
1046 (and meaningless) warnings from chirping during
1050 - some more bootstrapping is now done on the new
1053 * Class::MOP::Class::Immutable
1055 - constructor generation is now handled by
1056 the Class::MOP::Method::Constructor class
1058 * Class::MOP::Method::Constructor
1059 - created this to handle constructor generation
1060 in Class::MOP::Class::Immutable
1062 * Class::MOP::Attribute
1064 - attributes now delegate to the
1065 Class::MOP::Method::Accessor to generate
1068 * Class::MOP::Method::Accessor

1086 - adjusted tests for this
1087 - added the Class::MOP::Instance attributes

1099 encapsulate most of the work into the
1100 &get_method_map method
1101 - made several adjustments for the change
1102 in Class::MOP::Method
1103 - &add_attribute now checks if you are adding
1104 a duplicate name, and properly removes the

1107 - adjusted docs for this
1109 * Class::MOP::Class::Immutable
1110 - added caching of &get_method_map

1116 &list_all_package_symbols
1118 0.34 Sat. Aug. 26, 2006
1120 - added the %:methods attribute, which like
1121 the $:version and such just actually goes
1122 to the symbol table to get it's stuff.
1123 However, it makes the MOP more complete.
1125 - The &create method now requires that all
1126 but the package name now is passed in as
1127 named parameters. See docs for more info.
1128 - updated docs and tests for this
1130 * Class::MOP::Object
1131 - added &dump method to easily Data::Dumper

1154 - added tests for this
1156 * Class::MOP::Package
1157 - fixed an issue with perl 5.8.1 and how it deals
1158 with symbol tables. The namespace hash is now
1159 always reloaded from the symbol table.
1161 ~ lots of misc. documentation cleanup
1163 0.32 Sat. Aug. 12, 2006
1164 + added Class::MOP::Object so that the
1165 metamodel is more complete (and closer
1166 to what Perl 6 will probably be).
1168 * Class::MOP::Package
1169 - refactored entire class, this is now
1170 the primary gateway between the metaclass
1171 and the Perl 5 symbol table
1172 - added many tests for this

1179 use Class::MOP::Package methods instead
1181 * Class::MOP::Module
1182 - adding the $:version attribute in the bootstrap
1183 so that Module has a version as an attribute
1184 - see comment in Class::MOP for details
1185 - added the $:authority attribute to this module
1186 as well as an &identifier method, to bring us
1187 ever closer to Perl 6 goodness
1188 - I have added $AUTHORITY to all the modules
1189 - added tests for this

1205 anywhere within the class hierarchy
1207 * Class::MOP::Attribute
1208 - added &set_value and &get_value for getting
1209 the value of the attribute for a particular
1212 0.30 Wed. July 5, 2006
1213 ---------------------------------------
1214 This is the first version of Class::MOP
1215 to introduce the immutable features which
1216 will be used for optimizating the MOP.
1217 This support should still be considered
1218 experimental, but moving towards stability.
1219 ---------------------------------------
1221 * Created Class::MOP::Class::Immutable
1223 * Created the Class::MOP::Package and
1224 Class::MOP::Module classes to more
1225 closely conform to Perl 6's meta-model
1228 - now inherits from Class::MOP::Module
1229 - several methods moved to ::Module and
1230 ::Package and now inherited
1231 - added tests for this
1233 * Class::MOP::Instance
1234 - added an is_inlinable method to allow other
1235 classes to check before they attempt to optimize.
1236 - added an inline_create_instance to inline
1237 instance creation (of course)
1240 - the Class::MOP::Class::*_package_variable
1241 methods are all now methods of Class::MOP::Package
1242 and called *_package_symbol instead. This is
1243 because they are now more general purpose symbol
1244 table manipulation methods.
1246 0.29_02 Thurs. June 22, 2006
1247 ++ DEVELOPER RELEASE ++
1249 - small change in &create so that it behaves
1250 properly when inherited
1251 - small fix to &clone_instance
1253 0.29_01 Fri. May 12, 2006
1254 ++ DEVELOPER RELEASE ++
1255 - This release works in combination with
1256 Moose 0.09_01, it is a developer release

1303 and get_all_metaclass_instances method to allow
1304 access to all the cached metaclass objects.
1305 - attribute slot initialization is now the responsibility
1306 of the attribute itself, and construct_instance now
1307 delegates appropriately
1309 * Class::MOP::Attribute
1310 - attribute slot initialization is now the responsibility
1311 of the attribute itself, so we added a method for it
1312 called initialize_instance_slot

1316 initialize_instance_slot method
1318 0.24 Tues. April 11, 2006

1339 - added test case for this
1341 0.21 Wed. March 15, 2006
1343 - fixed issue where metaclasses are reaped from
1344 our cache in global destruction, and so are not
1345 available in DESTORY calls

1365 - methods are now blessed into Class::MOP::Method
1367 - added methods to install CLOS-style method modifiers
1368 - &add_before_method_modifier
1369 - &add_after_method_modifier
1370 - &add_around_method_modifier
1371 - added tests and docs for these
1372 - added &find_next_method_by_name which finds the
1373 equivalent of SUPER::method_name
1375 0.12 Thurs. Feb 23, 2006
1376 - reduced the dependency on B, no need to always
1380 - added docs to the C3 method dispatch order test

1386 - added example of changing method dispatch order to C3
1389 - changed how clone_instance behaves, it now only does a
1390 shallow clone (see docs for more details)
1391 - added docs and tests
1393 0.10 Tues Feb. 14, 2006
1394 ** This release was mostly about writing more tests and
1395 cleaning out old and dusty code, the MOP should now
1396 be considered "ready to use".
1398 - adding more tests to get coverage up a little higher,
1399 mostly testing errors and edge cases.
1400 - test coverage is now at 99%
1403 - no longer optionally exports to UNIVERSAL::meta or
1404 creates a custom metaclass generator, use the

1418 0.06 Thurs Feb. 9, 2006
1420 - adding new metaclass pragma to make setting up the
1421 metaclass a little more straightforward
1424 - clean up bootstrapping to include more complete
1425 attribute definitions for Class::MOP::Class and
1426 Class::MOP::Attribute (accessors, readers, writers,
1427 etc.) ... it is redundant, but is useful meta-info
1431 - fixing minor meta-circularity issue with &meta, it
1432 is now more useful for subclasses
1433 - added &get_attribute_map as an accessor for the
1434 hash of attribute meta objects
1435 - &compute_all_applicable_attributes now just returns
1436 the attribute meta-object, rather than the HASH ref
1437 since all the same info can be gotten from the
1438 attribute meta-object itself
1439 - updated docs & tests to reflect
1440 - added &clone_instance method which does a deep clone
1441 of the instance structure created by &construct_instance
1442 - added docs & tests for this
1443 - added Clone as a dependency
1444 - added &new_object and &clone_object convience methods to
1445 return blessed new or cloned instances
1446 - they handle Class::MOP::Class singletons correctly too
1447 - added docs & tests for this
1448 - cleaned up the &constuct_class_instance so that it behaves
1449 more like &construct_instance (and managed the singletons too)
