1 Revision history for Perl extension Class-MOP.
5 - make_immutable issues a warning instead of overriding a
6 DESTROY method on immutable classes. (Dylan William Hardison).
9 * Class::MOP::Attribute
10 - Allow default values to be Class::MOP::Methods. (Florian
12 - Test the above. (Rhesa Rozendaal)
13 - Tweak original commit so the intent matches the accepted
14 behavior (Nicholas Perez)
17 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
20 - Add direct_subclasses method (Sartak)
21 - Tests for subclasses and direct_subclasses (Sartak)
22 - subname is no longer used unconditionally in add_method, but
23 only if the code reference's name is '__ANON__' (nothingmuch)
24 - Add a hook for _superclasses_updated (Sartak)
27 - Remove long, old warning about possibly outdated modules
30 0.84 Tue, May 12, 2009
32 - Depend on Text::Exception 0.27 to avoid failing tests ond old
36 - Made is_class_loaded a little stricter. It was reporting that
37 a class was loaded if it merely had an @ISA variable in its
38 stash. Now it checks that the @ISA var has elements in it.
39 - Deprecate in_global_destruction and subname re-exporting
43 - Explicitly use Devel::GlobalDestruction and Sub::Name
47 - Disable prototype mismatch warnings for add_package_symbol.
50 0.83 Mon, April 27, 2009
52 - Fix segfault when calling get_method_map on a metaclass for an empty
55 0.82_02 Fri, April 24, 2009
56 * Class::MOP::Method::Inlined
57 - Don't inline if the expected method is not defined at all (happens with
58 e.g. Moose::Object::_new is the expected method due to an overridden
61 - Some tests were trying to load Class::MOP::Immutable, which
62 was removed in 0.82_01.
64 0.82_01 Thu, April 23, 2009
65 * Class::MOP::Immutable (and others)
66 - Refactor the immutability system to use a pre-defined class
67 for the immutable metaclass of Class::MOP::Class::Immutable::$class
68 - Rather than generating methods into this class every time, use
69 a Trait (basic mixin) to supply the cached methods
70 - Remove the hack that returns the mutable metaclass for
71 metacircularity in order to provide consistent meta-metaclasses
72 for the Moose compatibility handling code
73 (mst broke it, nothingmuch fixed it)
75 0.82 Mon, April 20, 2009
77 - The deprecation wrappers for some renamed methods were not
78 passing arguments to the new method. (nothingmuch)
80 * Class::MOP::Immutable
81 - Warn during immutablization if the local class provides its own
82 constructor, to parallel the warning in Moose when a superclass
83 provides its own constructor (doy)
85 0.81 Tue, April 7, 2009
88 * Class::MOP::Instance
89 * Class::MOP::Attribute
90 * Class::MOP::Method::Accessor
91 * Class::MOP::Method::Constructor
92 - Include stack traces in the deprecation warnings introduced in
93 0.80_01. (Florian Ragwitz)
96 - Avoid c compiler warnings by declaring some unused function
97 arguments. (Florian Ragwitz)
99 0.80_01 Sun, April 5, 2009
101 - Make sure to preserve any compiler flags already defined in
102 Config.pm. Patch by Vincent Pit. RT #44739.
104 * Many methods have been renamed with a leading underscore, and a
105 few have been deprecated entirely. The methods with a leading
106 underscore are consider "internals only". People writing
107 subclasses or extensions to Class::MOP should feel free to
108 override them, but they are not for "public" use.
111 - construct_class_instance => _construct_class_instance (use new_object)
112 - construct_instance => _construct_instance (use new_object)
113 - check_metaclass_compatibility => _check_metaclass_compatibility
114 - create_meta_instance => _create_meta_instance (use get_meta_instance)
115 - clone_instance => _clone_instance (use clone_object)
116 - compute_all_applicable_methods is deprecated, use get_all_methods
117 - compute_all_applicable_attributes is deprecated, use get_all_attributes
119 - Class::MOP::Instance
120 - bless_instance_structure is deprecated and will be removed
124 - create has been renamed to _instantiate_module. This method
125 does not construct an object, it evals some code that
126 creates the relevant package in Perl's symbol table.
128 - Class::MOP::Method::Accessor
129 - initialize_body => _initialize_body (this is always called
130 when an object is constructed)
131 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
133 - Class::MOP::Method::Constructor
134 - initialize_body => _initialize_body (this is always called
135 when an object is constructed)
136 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
137 - attributes => _attributes
138 - meta_instance => _meta_instance
140 0.80 Wed, April 1, 2009
142 - Call user_class->meta in fewer places, with the eventual goal
143 of allowing the user to rename or exclude ->meta
144 altogether. Instead uses Class::MOP::class_of. (Sartak)
147 - New class_of function that should be used to retrieve a
148 metaclass. This is unlike get_metaclass_by_name in that it
149 accepts instances, not just class names. (Sartak)
152 - load_first_existing_class didn't actually load the first
153 existing class; instead, it loaded the first existing and
154 compiling class. It now throws an error if a class exists (in
155 @INC) but fails to compile. (hdp)
159 - we had some semi-buggy code that purported to provide a
160 HAS_ISAREV based on whether mro had get_isarev (due to an
161 oversight, it always returned 1). Since mro and MRO::Compat
162 have always had get_isarev, HAS_ISAREV was pointless. This
163 insight simplified the subclasses method by deleting the
164 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
166 0.79 Fri, March 29, 2009
167 * No changes from 0.78_02.
169 0.78_02 Thu, March 26, 2009
171 * Class::MOP::Immutable
172 - A big backwards-incompatible refactoring of the Immutable API,
173 and the make_immutable/make_mutable pieces of the Class
174 API. The core __PACKAGE__->meta->make_immutable API remains
175 the same, however, so this should only affect the most
179 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
180 has been fixed to be backwards compatible with 5.8.x.
183 - Add a hook for rebless_instance_away (Sartak)
184 - Use blessed instead of ref to get an instance's class name
185 in rebless_instance. (Sartak)
187 0.78_01 Wed, March 18, 2009
189 - Revised and reorganized all of the API documentation. All
190 classes now have (more or less) complete API documentation.
193 * Class::MOP::Instance
194 - Reblessing into a package that supports overloading wasn't
195 properly adding overload magic to the object due to a bug
196 in (at least) 5.8.8. We now use $_[1] directly which seems
197 to set the magic properly. (Sartak)
199 * Class::MOP::Attribute
200 - The process_accessors method is now private. A public alias
201 exists (and will stick around for a few releases), but it
202 warns that calling the public method is deprecated.
204 * Class::MOP::Method::Generated
205 - Removed the new and _new methods, since this is an abstract
206 base class, and all existing subclasses implement their own
210 - Stop is_class_loaded from thinking a class is loaded if it
211 only has an empty GV (Florian Ragwitz).
212 - Add a test for this (Yappo).
213 - Refactor get_all_package_symbols to allow short-circuiting
215 - Use this in is_class_loaded (Florian Ragwitz).
216 - Stop segfaulting when trying to get the name from a sub that's
217 still being compiled (Florian Ragwitz).
218 - Add tests for this (Florian Ragwitz).
219 - Prefix all public symbols with "mop_" (Florian Ragwitz).
220 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
221 - Simplify creating simple xs reader methods (Florian Ragwitz).
222 - Make everything compile with c++ compilers (Florian Ragwitz).
223 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
226 - Remove optional test plans for tests depending on Sub::Name as
227 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
230 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
232 0.78 Mon, February 23, 2009
233 * No changes from 0.77_01
235 0.77_01 Sun, February 22, 2009
237 - This package now requires its XS components. Not using
238 Sub::Name lead to different behavior and bugginess in the pure
239 Perl version of the code. A Moose test would fail when run
240 against the pure Perl version of this code.
242 * Class::MOP::Instance
243 - The inline_* methods now quote attribute names themselves, and
244 don't expect to receive a quoted value.
247 0.77 Sat, February 14, 2009
249 - Avoid assertion errors on debugging perls in is_class_loaded
253 - Fixed various corner cases where is_class_loaded incorrectly
254 returned true for a class that wasn't really loaded. (Dave
258 - Add get_all_method_names (Sartak)
259 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
261 * Class::MOP::Package
262 - Disable deprecated get_all_package_symbols in list
263 context. (Florian Ragwitz)
266 - Make sure we generate a BSD-compatible Makefile (Florian
270 - The misspelled "check_metaclass_compatability" method we've
271 kept around for backwards compat_i_bility will be removed in a
272 near future release. You've been warned.
274 0.76 Thu, January 22, 2009
275 * Class::MOP::Method::Generated
276 - Added new private methods to support code generation, which
277 are being used by Moose and can be used by MooseX
279 - Generated methods are now generated with a #line directive
280 reflecting the source of the generated method. (nothingmuch)
283 - Clarified documentation of methods that return
284 Class::MOP::Method objects. (doy)
287 - Clarified documentation of the metaclass cache methods. (Sartak)
290 - Add test showing how the xs Class::MOP::is_class_loaded can
291 be made to operate differently to the pure perl version (t0m)
293 0.75 Wed, December 31, 2008
295 - A class that was made immutable and then mutable could end up
296 sharing an immutable transformer object
297 (Class::MOP::Immutable) with other classes, leading to all
298 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
300 0.74 Tue, December 25, 2008
302 - Add an xs implementation of Class::MOP::is_class_loaded (closes
303 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
304 - Changed internals to make prehashing of hash keys easier and less
305 error-prone. (Florian Ragwitz)
307 - Fix documentation to show that around modifiers happen on both
308 sides of the modified method. (Dave Rolsky)
310 0.73 Tue, December 16, 2008
312 - Don't use Perl_mro_meta_init. It's not part of the public perl
313 api. Fixes failures to build on Win32 (RT #41750). (Florian
315 * t/082_get_code_info.t
316 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
317 munger anonymous subs when under -d and so making the tests
318 succeed in that case.
320 0.72 Mon, December 8, 2008
321 * Class::MOP::Package
322 - Pass options to _new, so subclass' attributes can be
325 - In the docs, indicate that package_name and name are required
326 when calling ->wrap (Stefan O'Rear)
328 0.71_02 Fri, December 5, 2008
329 * Class::MOP::Immutable
330 - Added a new attribute, inlined_constructor, which is true if
331 the constructor was inlined.
332 * Class::MOP::Package
333 - Make get_all_package_symbols return a hash ref in scalar
334 context and deprecate calling it in list context with a
335 warning. (Florian Ragwitz)
337 - Various improvements and refactoring, making things more robust and
338 easier to maintain. (Florian Ragwitz)
340 0.71_01 Wed, December 3, 2008
342 - Add an "execute" method to invoke the body so
343 we can avoid using the coderef overload (Sartak)
344 * Class::MOP::Immutable
345 - When we memoize methods, get their results lazily
346 to remove some compile-time cost (Sartak)
347 - Small speedup from eliminating several method
350 - Some small internal tweaks to try to reduce the number of
351 times we call get_method_map when bootstrapping the MOP. This
352 might make loading Class::MOP (and Moose) a little
353 faster. (Dave Rolsky)
354 - Implemented an optional XS version of get_method_map. Mostly
355 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
356 help form Florian Ragwitz. (Dave Rolsky)
357 - Make the behaviour of of get_all_package_symbols (and
358 therefore get_method_map) consistent for stub methods. Report
359 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
361 0.71 Wed November 26, 2008
364 - Actual package creation has moved upward from
365 Class to Module so that Moose roles can share
368 0.70_01 Mon, November 19, 2008
370 - Fixes for failures with blead (Florian Ragwitz)
371 - Silenced compiler warnings (Florian Ragwitz)
373 0.70 Fri, November 14, 2008
375 - Fixed an odd corner case where the XS version of
376 get_all_package_symbols could cause a segfault. This only
377 happened with inlined constants in Perl 5.10.0 (Florian
380 0.69 Fri, November 7, 2008
381 * Class::MOP::Method::Wrapped
382 - Added introspection methods for method modifiers (Dave Rolsky)
385 0.68 Fri October 24, 2008
387 - Make load_class require by file name instead of module name.
388 This stops confusing error messages when loading '__PACKAGE__'.
390 - Add load_one_class_of function to enable you to load one of a
391 list of classes, rather than having to call load_class multiple
392 times in an eval. (t0m)
394 0.67 Tue October 14, 2008
396 - Call a method on the class after setting the superclass list
397 so that we can get Perl to detect cycles before MRO::Compat
398 spirals into an infinite loop (sartak)
399 - Reported by Schwern, [rt.cpan.org #39001]
400 - In create(), pass unused options on to initialize()
401 - added test for this
403 0.66 Sat September 20, 2008
404 !! This release has an incompatible change regarding !!
405 introspection of a class's method with Class::MOP::Class !!
408 - We (us maintainers) now run all tests with XS and then without
409 XS, which should help us catch skew between the XS/pure Perl
413 ! The alias_method method has been deprecated. It now simply
414 calls add_method instead. There is no distinction between
415 aliased methods and "real" methods.
417 This means that methods added via alias_method now show up as
418 part of the class's method list/map. This is a backwards
419 incompatible change, but seems unlikely to break any
420 code. Famous last words. (Dave Rolsky)
423 - Fixed the spelling of "compatibility", but we still have a
424 "check_metaclass_compatability" method for backwards
427 0.65 Mon September 1, 2008
428 For those not following the series of dev releases, the changes
429 from 0.64 from 0.65 can mostly be summed up as a lot performance
430 improvements by nothingmuch, including new optional XS versions of
431 some methods. Also, Class::MOP now works _without_ any XS modules,
432 for sad systems without a compiler.
435 - Added name and package_name XS accessors, and make sure all
436 the XS and Perl versions work the same way. (Dave Rolsky)
439 - The XS versions of various methods just returned undef when
440 called class methods, rather than dying like the pure Perl
441 versions. (Dave Rolsky)
443 0.64_07 Fri August 29, 2008
445 - Silenced warnings that managed to break Moose tests when XS
446 was loaded. (Dave Rolsky)
447 - Some XS versions of methods were ignored because of typos in
448 MOP.xs. (Dave Rolsky)
450 0.64_06 Mon August 25, 2008
451 * Class::MOP (MOP.xs)
452 - Another MS VC++ fix, cannot declare a variable in the middle
453 of a scope (Taro Nishino).
455 0.64_05 Sun August 24, 2008
457 - None of the dev releases actually loaded the XS properly, but
458 we silently fell back to the pure Perl version of the
461 * Class::MOP (MOP.xs)
462 - Replaced some code that used functions not available on Visual
463 C++ with some Perl XS API bits (Dave Rolsky).
465 0.64_04 Sat August 23, 2008
467 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
469 * pod.t and pod_coveraget.t
470 - These are no longer shipped with the tarball because of bogus
471 failures from CPAN testers. (Dave Rolsky)
473 0.64_03 Thu August 21, 2008
474 * Class::MOP::Package
475 - Some (legit) code was misparsed by earlier 5.8.x
476 releases. (nothingmuch)
479 - Fix a constant in void context warning (nothingmuch)
481 0.64_02 Thu August 21, 2008
482 * Makefile.PL and Class::MOP
483 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
486 - Add missing prereqs that got lost in the switch away from
489 * Class::MOP::Instance
490 - New method - get_all_attributes (nothingmuch)
492 0.64_01 Wed August 20, 2008
494 - We now check to see if you have a compiler. If you don't, the
495 module installs without some XS bits, but will work the same
496 as with XS. This should make it easier to install on platforms
497 without a compiler (like Windows). (Dave Rolsky)
500 - Perl 6 style attribute naming replaced with sane style ('methods', not
501 '%!methods'). These changes should not impact any existing API uses.
505 - Quite a number of optimizations based on profiling, including
506 allowing constructors to take hash references instead of
507 hashes, duplicating some frequently used code in XS, and
508 making constructors immutable. These changes should not impact
509 any existing API uses. (nothingmuch)
512 - Constructors now respect the meta attributes of their subclasses,
513 facilitating MOP extensibility. More related changes will happen in the
514 next several releases. (nothingmuch)
517 - New method - get_all_methods, replaces the deprecated
518 compute_all_applicable_methods. get_all_attributes provided for
519 consistency (nothingmuch)
520 - New method - wrap_method was refactored out of get_method_map
522 - New API for meta instance invalidation - invalidate_meta_instance,
523 invalidate_meta_instances, add_dependent_meta_instance,
524 remove_dependent_meta_instance, called automatically when attribute
525 definitions change and allows notification of dependent subclasses.
528 0.64 Sun August 3, 2008
529 * Class::MOP::Immutable
530 - fixing subtle edge case in immutable when you
532 - clean up option processing (nothingmuch)
534 * Class::MOP::Instance
535 - inlined initialize slot didn't match
536 non-inlined (nothingmuch)
538 0.63 Mon July 7, 2008
540 - load_class will initialize a metaclass even if
541 the class is already loaded (sartak)
542 - load_class now returns the metaclass instance
543 instead of just 1 (sartak)
546 - better error messages (sartak and Dave Rolsky)
548 0.62 Wed June 18, 2008
549 - in is_class_loaded, recognize scalar references (as opposed to globs) in
550 the symbol table as methods (these are optimized constant subs)
552 0.61 Fri. June 13, 2008
553 - Okay, lets give this another try and see if PAUSE
554 recognizes it correct this time.
556 0.60 Thurs. Jun 12, 2008
557 - Fixed a version number issue by bumping all modules
560 0.59 Thurs. Jun 12, 2008
561 !! Several fixes resulting in yet another 25-30% speedup !!
564 - now stores the instance of the instance
565 metaclass to avoid needless recomputation
566 and deletes it when the cache is blown
567 - introduce methods to query Class::MOP::Class for
568 the options used to make it immutable as well as
569 the proper immutable transformer. (groditi)
571 * Class::MOP::Package
572 - {add, has, get, remove}_package_symbol all
573 now accept a HASH ref argument as well as the
574 string. All internal usages now use the HASH
578 - MOP.xs does sanity checks on the coderef
580 - is_class_loaded check now uses code that
581 was improved in Moose's ClassName type
583 - nonsensical (undef, empty, reference) class
584 names now throw a more direct error in
586 - tests for this and other aspects of
592 Class::MOP::Method::Wrapped
593 Class::MOP::Attribute
594 - switched usage of reftype to ref because
597 0.58 Thurs. May 29, 2008
598 (late night release engineering)--
600 - fixing the version is META.yml, no functional
601 changes in this release
603 0.57 Wed. May 28, 2008
604 !! Several speedups resulting in 20-25% speedups !!
605 || (thanks to konobi, groditi, mst & CataMoose) !!
608 - made get_method_map use list_all_package_symbols
609 instead of manually grabbing each symbol
610 - streamlining &initialize somewhat, since it gets
613 * Class::MOP::Package
614 - made {get, has}_package_symbol not call
616 - inlining a few calls to &name with
617 direct HASH access key access
618 - added get_all_package_symbols to fetch
619 a HASH of items based on a type filter
620 similar to list_all_package_symbols
621 - added tests for this
624 Class::MOP::Method::Constructor
625 Class::MOP::Method::Generated
626 Class::MOP::Method::Accessor
627 - added more descriptive error message to help
628 keep people from wasting time tracking an error
629 that is easily fixed by upgrading.
631 * Class::MOP::Immutable
632 - Don't inline a destructor unless the user actually
634 - added tests for this
636 0.56 Saturday, May 24, 2008
638 - we now get the &check_package_cache_flag
639 function from MRO::Compat
640 - All XS based functionality now has a
641 Pure Perl alternative
642 - the CLASS_MOP_NO_XS environment variable
643 can now be used to force non-XS versions
646 * Class::MOP::Attribute
647 - add has_read_method and has_write_method
648 - get_{read,write}_method_ref now wraps the
649 anon-sub ref in the method metaclass when
651 - added tests for this
653 * Class::MOP::Immutable
654 - added the ability to "wrap" methods when
655 making the class immutable
658 - now handling the edge case of ->meta->identifier
659 dying by wrapping add_package_symbol to specifically
660 allow for it to work.
661 - added tests for this
663 * Class::MOP::Attribute
665 Class::MOP::Immutable
666 - any time a method meta object is constructed
667 we make sure to pass the correct package and
668 method name information
671 Class::MOP::Method::Wrapped
672 Class::MOP::Method::Generated
673 Class::MOP::Method::Accessor
674 Class::MOP::Method::Consructor
675 - the &wrap constructor method now requires that a
676 'package_name' and 'name' attribute are passed. This
677 is to help support the no-XS version, and will
678 throw an error if these are not supplied.
679 - all these classes are now bootstrapped properly
680 and now store the package_name and name attributes
683 ~ Build.PL has been removed since the
684 Module::Install support has been removed
686 0.55 Mon. April 28, 2008
687 - All classes now have proper C3 MRO support
688 - added MRO::Compat as a dependency to allow
689 for the C3 MRO support to Just Work in all
693 - rebless_instance now returns the instance
694 it has just blessed, this is mostly to
696 - set the attr correctly in rebless_instance
697 when it has no init_arg
698 - tweaked &linear_isa and &class_precedence_list
699 to support c3 classes.
701 0.54 Fri. March, 14, 2008
704 - making sure that load_class never gets
705 passed a value from @_ or $_ to squash
706 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
709 - make_{immutable,mutable} now return 1
711 - improved error handling in ->create method
712 - rebless_instance now takes extra params which
713 will be used to populate values
714 - added tests for this
717 - localizing the Data::Dumper configurations so
718 that it does not pollute others (RT #33509)
724 Class::MOP::Attribute
725 - these classes no longer define their own ->meta,
726 but instead just inherit from Class::MOP::Object
728 * Class::MOP::Instance
729 Class::MOP::Immutable
730 - these classes now inherit from Class::MOP::Object
733 - fixed the filename length on several
734 test files so we install on VMS better
736 - fixed incorrect use of catdir when it
737 should be catfile (RT #32385)

740 ~~ several doc. fixes and updates ~~
743 Class::MOP::Method::Constructor

745 - making init_arg accept an undefined value
746 to indicate that no constructor args can
747 be passed (thanks to nothingmuch)
748 - added tests for this
749 - added attribute initializer attribute (rjbs)
752 - making this use the new init_arg => undef
753 feature instead of the silly hack from
754 before (thanks to nothingmuch)

758 - fixed bug in rebless_instance
761 * Class::MOP::Method::Constructor

765 0.51 Mon. Jan. 14, 2008
766 ~~~ some misc. doc. fixes ~~~
767 ~~ updated copyright dates ~~
770 - now sets the IS_RUNNING_ON_5_10
771 constant so that we can take advantage
772 of some of the nice bits of 5.10
775 - uses the IS_RUNNING_ON_5_10 flag to
776 optimize the &linearized_isa method
777 and avoid the hack/check for circular
778 inheritence in &class_precedence_list
779 - added rebless_instance method (Sartak)
780 - added tests for this
782 * Class::MOP::Immutable
783 - the immutable class now keeps track of

797 * Class::MOP::Immutable
798 - fixed a bug (see above)
800 * Class::MOP::Attribute
803 0.49 Fri. Dec. 14, 2007
804 !! Class::MOP now loads 2 x faster !!
805 !! with XS speedups (thanks konobi) !!
808 - removed the dependency on B
809 - added two XS functions (thanks konobi)
810 - get_code_info($code) which replaces all
811 the B fiddling we were doing with
812 faster/leaner XS level fiddling
813 - check_package_cache_flag($pkg_name) which
814 returns the PL_sub_generation variable to
815 be used to help manage method caching.
818 In 5.10 or greater this will actually
819 use the mro::get_pkg_gen instead to give
820 even more accurate caching information.
821 blblack++ for that stuff :)
824 - added the &subclasses method (thanks rlb)
825 - added the update_package_cache_flag and
826 reset_package_cache_flag which help keep
827 track of when we need to re-fetch the
829 - Several small improvements to take advantage
830 of the new method map caching features
832 0.48 Mon. Nov. 26, 2007
833 * Class::MOP::Attribute
834 - fixed get_read/write_method to handle the

842 - added more tests for this
844 0.46 Fri. Nov. 23, 2007
846 - added the linearized_isa method instead of constantly
847 pruning duplicate classes (this will be even more
848 useful in the 5.10-compat version coming soon)
850 * Class::MOP::Attribute
851 - added the get_read_method_ref and get_write_method_ref
852 methods which allow you to retrieve a CODE ref which
853 can always be used to read or write an attribute.
855 0.45 Thurs. Nov. 13, 2007
856 * Class::MOP::Attribute
857 - Fix error message on confess (groditi)
859 0.44 Thurs. Nov. 13, 2007

867 - optimise metaclass-already-exists check in
868 construct_class_instance (groditi)
869 - duplicate check into initialize to save a
870 call through (groditi)
872 * Class::MOP::Attribute

878 - Make predicates check for the existence of a value, not whether
879 it is defined (groditi)
881 * Class::MOP::Method::Accessor
882 - made this a subclass of Class::MOP::Method::Generated
883 - removed the relevant attributes
885 * Class::MOP::Method::Constructor
886 - fixed the cached values we had to be more sane
887 - made this a subclass of Class::MOP::Method::Generated
888 - fixed generated constructor so it properly handles
890 - added tests for this
891 - added the option to allow for both inlined and
892 non-inlined constructors.
893 - Update inlined methods for builder and predicate changes (groditi)
895 * Class::MOP::Method::Generated
896 - added this class as an abstract base for the
897 Class::MOP::Method::{Constructor,Accessor} classes

907 0.42 Mon. July 16, 2007
908 !!! Horray for mst, he fixed it !!!
910 * Class::MOP::Package
911 - alter symbol table handling to deal with 5.8.x and 5.9.x
914 - Get rid of the crappy workaround from 0.40/41
916 0.41 Sun. July 15, 2007
918 Arghh!!! My TODO test didn't work, so I handle
919 it manually now so that people can use this
920 with 5.9.5/bleadperl without issue.
922 0.40 Tues, July 3, 2007
924 ~ marked a test in 003_methods.t as TODO
925 for perl 5.9.5 (this test is irrelvant to
926 the module functioning on 5.9.5 for the most
929 0.39 Mon. June 18, 2007
930 * Class::MOP::Immutable
931 - added make_metaclass_mutable + docs (groditi)
932 - removed unused variable
933 - added create_immutable_transformer
934 necessary for sane overloading of immutable behavior
935 - tests for this (groditi)
938 - Immutability can now be undone,
939 added make_mutable + tests + docs (groditi)
940 - Massive changes to the way Immutable is done
941 for details see comments next to make_immutable
942 This fixes a bug where custom metaclasses broke
943 when made immutable. We are now keeping one immutable
944 metaclass instance per metaclass instead of just one
945 to prevent isa hierarchy corruption. Memory use will go
946 up, but I suspect it will be neglible.
947 - New tests added for this behavior. (groditi)
949 0.38 Thurs. May 31, 2007
950 ~~ More documentation updates ~~
952 * Class::MOP::Package

958 - added get_read_method and get_write_method
959 thanks to groditi for this code, tests
961 - added tests and POD for this
964 - fixed RT issue #27329, clone object now
965 handles undef values correctly.
966 - added tests for this
967 - Corrected anon-class handling so that they
968 will not get reaped when instances still
969 exist which need to reference them. This is
970 the correct behavior, hopefully this is an
971 obscure enough feature that there are not too
972 many work arounds out in the wild.
973 - added tests for this by groditi
974 - updated docs to explain this
977 - load custom metaclasses automatically (thanks groditi)
978 - added tests for this behavior
980 0.37 Sat. March 10, 2007

987 * Class::MOP::Attribute
988 - default now checks the instance with defined to
989 avoid setting off bool-overloads (found by Carl Franks)
993 - bad name in a test, causing meaningless failuress.
999 - All attribute names are now consistent and follow Perl 6
1000 style (prefixed with the sigil, and ! as the twigil for
1001 private attrs). This should not affect any code, unless
1002 you broke encapsulation, in which case, it is your problem
1005 !! Class::MOP::Class::Immutable has been removed
1007 * Class::MOP::Method::Constructor
1008 - this has been moved out of Class::MOP::Class::Immutable
1009 and is a proper subclass of Class::MOP::Method now.
1012 - this module now uses Class::MOP::Immutable for the
1013 immutable transformation instead of
1014 Class::MOP::Class::Immutable.
1016 + Class::MOP::Immutable
1017 - this module now controls the transformation from a mutable
1018 to an immutable version of the class. Docs for this will
1019 be coming eventually.
1022 0.36 Sun. Nov. 5, 2006
1024 - added a few 'no warnings' lines to keep annoying
1025 (and meaningless) warnings from chirping during
1029 - some more bootstrapping is now done on the new
1032 * Class::MOP::Class::Immutable
1034 - constructor generation is now handled by
1035 the Class::MOP::Method::Constructor class
1037 * Class::MOP::Method::Constructor
1038 - created this to handle constructor generation
1039 in Class::MOP::Class::Immutable
1041 * Class::MOP::Attribute
1043 - attributes now delegate to the
1044 Class::MOP::Method::Accessor to generate
1047 * Class::MOP::Method::Accessor
1048 - all accessor generation functions from
1049 Class::MOP::Attribute have been moved here

1065 - adjusted tests for this
1066 - added the Class::MOP::Instance attributes
1069 * Class::MOP::Method

1078 encapsulate most of the work into the
1079 &get_method_map method
1080 - made several adjustments for the change
1081 in Class::MOP::Method
1082 - &add_attribute now checks if you are adding
1083 a duplicate name, and properly removes the

1086 - adjusted docs for this
1088 * Class::MOP::Class::Immutable
1089 - added caching of &get_method_map
1090 - fixed issue with &get_package_symbol
1091 - cleaned up the methods that die (patch by David Wheeler)

1095 &list_all_package_symbols
1097 0.34 Sat. Aug. 26, 2006
1099 - added the %:methods attribute, which like
1100 the $:version and such just actually goes
1101 to the symbol table to get it's stuff.
1102 However, it makes the MOP more complete.
1104 - The &create method now requires that all
1105 but the package name now is passed in as
1106 named parameters. See docs for more info.
1107 - updated docs and tests for this
1109 * Class::MOP::Object
1110 - added &dump method to easily Data::Dumper

1133 - added tests for this
1135 * Class::MOP::Package
1136 - fixed an issue with perl 5.8.1 and how it deals
1137 with symbol tables. The namespace hash is now
1138 always reloaded from the symbol table.
1140 ~ lots of misc. documentation cleanup
1142 0.32 Sat. Aug. 12, 2006
1143 + added Class::MOP::Object so that the
1144 metamodel is more complete (and closer
1145 to what Perl 6 will probably be).

1149 the primary gateway between the metaclass
1150 and the Perl 5 symbol table
1151 - added many tests for this

1160 * Class::MOP::Module
1161 - adding the $:version attribute in the bootstrap
1162 so that Module has a version as an attribute
1163 - see comment in Class::MOP for details
1164 - added the $:authority attribute to this module
1165 as well as an &identifier method, to bring us
1166 ever closer to Perl 6 goodness
1167 - I have added $AUTHORITY to all the modules
1168 - added tests for this

1187 - added &set_value and &get_value for getting
1188 the value of the attribute for a particular
1191 0.30 Wed. July 5, 2006
1192 ---------------------------------------
1193 This is the first version of Class::MOP
1194 to introduce the immutable features which
1195 will be used for optimizating the MOP.
1196 This support should still be considered
1197 experimental, but moving towards stability.
1198 ---------------------------------------
1200 * Created Class::MOP::Class::Immutable
1202 * Created the Class::MOP::Package and
1203 Class::MOP::Module classes to more
1204 closely conform to Perl 6's meta-model
1207 - now inherits from Class::MOP::Module
1208 - several methods moved to ::Module and
1209 ::Package and now inherited
1210 - added tests for this
1212 * Class::MOP::Instance
1213 - added an is_inlinable method to allow other
1214 classes to check before they attempt to optimize.
1215 - added an inline_create_instance to inline
1216 instance creation (of course)
1219 - the Class::MOP::Class::*_package_variable
1220 methods are all now methods of Class::MOP::Package
1221 and called *_package_symbol instead. This is
1222 because they are now more general purpose symbol
1223 table manipulation methods.
1225 0.29_02 Thurs. June 22, 2006
1226 ++ DEVELOPER RELEASE ++
1228 - small change in &create so that it behaves

1284 - attribute slot initialization is now the responsibility
1285 of the attribute itself, and construct_instance now
1286 delegates appropriately
1288 * Class::MOP::Attribute
1289 - attribute slot initialization is now the responsibility
1290 of the attribute itself, so we added a method for it
1291 called initialize_instance_slot

1320 0.21 Wed. March 15, 2006
1322 - fixed issue where metaclasses are reaped from

1348 - &add_after_method_modifier
1349 - &add_around_method_modifier
1350 - added tests and docs for these
1351 - added &find_next_method_by_name which finds the
1352 equivalent of SUPER::method_name
1354 0.12 Thurs. Feb 23, 2006
1355 - reduced the dependency on B, no need to always
1359 - added docs to the C3 method dispatch order test
1360 - fixed missing Algorithm::C3 dependency by making

1369 shallow clone (see docs for more details)
1370 - added docs and tests
1372 0.10 Tues Feb. 14, 2006
1373 ** This release was mostly about writing more tests and
1374 cleaning out old and dusty code, the MOP should now
1375 be considered "ready to use".
1377 - adding more tests to get coverage up a little higher,
1378 mostly testing errors and edge cases.
1379 - test coverage is now at 99%
1382 - no longer optionally exports to UNIVERSAL::meta or
1383 creates a custom metaclass generator, use the

1397 0.06 Thurs Feb. 9, 2006
1399 - adding new metaclass pragma to make setting up the
1400 metaclass a little more straightforward
1403 - clean up bootstrapping to include more complete
1404 attribute definitions for Class::MOP::Class and
1405 Class::MOP::Attribute (accessors, readers, writers,
1406 etc.) ... it is redundant, but is useful meta-info
1410 - fixing minor meta-circularity issue with &meta, it
1411 is now more useful for subclasses
1412 - added &get_attribute_map as an accessor for the
1413 hash of attribute meta objects
1414 - &compute_all_applicable_attributes now just returns
1415 the attribute meta-object, rather than the HASH ref
1416 since all the same info can be gotten from the
1417 attribute meta-object itself
1418 - updated docs & tests to reflect
1419 - added &clone_instance method which does a deep clone
1420 of the instance structure created by &construct_instance

1430 that metaclasses are upward and downward compatible.
1431 - added tests and docs for this
1434 - adjusting code to use the &Class::MOP::Class::meta
1436 - adjusting code to use the metaclass pragma
1438 0.05 Sat Feb. 4, 2006

1441 attributes which contain a metaclass name to use for
1442 attributes/methods respectively
1445 - bootstrap additional attributes for Class::MOP::Class
1448 - adjusted the example code and tests to use the new
1449 &attribute_metaclass feature of Class::MOP::Class
1450 - added new example:
1453 0.04 Fri Feb. 3, 2006
1455 - some documentation suggestions from #perl6
