1 Revision history for Perl extension Class-MOP.
5 - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
8 - Make sure XS code handles magical scalars correctly. (Goro Fuji)
11 - Deprecated features have been moved to their own module,
12 Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)
17 - Move get_method_map and its various scaffolding into Package. (hdp)
20 - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
21 the first argument, rather than just a coderef. (doy)
23 * Class::MOP::Attribute
25 - Allow attribute names to be false (while still requiring them to be
29 * Class::MOP::Method::Wrapped
30 - Fixing variable usage issues with the patch from previous
31 version, not properly using lexicals in the for
35 Japan Perl Association has sponsored Goro Fuji to improve startup
36 performance of Class::MOP and Moose. These enhancements may break
37 backwards compatibility if you're doing (or using) complex
38 metaprogramming, so, as always, test your code!
39 http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html
43 - Anonymous classes were not completely destroyed when they went
44 out of scope, leading to a memory leak. RT #47480. (Goro
48 - The get_method, has_method, and add_method methods no longer
49 use get_method_map. Method objects are instantiated
50 lazily. This significantly improves Class::MOP's load
54 - Inline fewer metaclass-level constructors since the ones we
55 have are perfectly fine. This reduces the number of string
58 * Class::MOP::Method::Wrapped
59 - If a method modifier set $_, this caused the modifier to blow
60 up, because of some weird internals. (Jeremy Stashewsky)
64 * Class::MOP::Class::Immutable::Trait
65 - Made the Trait act like a role with a bunch of "around"
66 modifiers, rather than sticking it in the inheritance
67 hierarchy. This fixes various problems that caused with
68 metaclass compatibility, which broke Fey::ORM.
71 - Allow a blessed code reference as the method body. Fixes a
72 problem interaction with MooseX::Types. (ash)
74 * Class::MOP::Instance
75 - add inline version of rebless_instance_structure. (doy)
76 - change inline_slot_access to use single quotes (gphat)
78 0.88 Tue, Jun 23, 2009
80 - Moved the __INSTANCE__ parameter to _construct_instance from
82 - Fixed some issues involving metaclasses of metaclasses and
85 0.87 Sun, Jun 21, 2009
87 - Made sure to always local-ize $@ and $SIG{__DIE__} before
88 calling an eval. Fixes RT #45973.
91 - Synced docs about immutability with the current reality (which
92 changed back in 0.82_01)
93 - Removed the immutable_transformer method, which had been
94 returning undef since 0.82_01 anyway.
97 - Got rid of tests which needed Moose and improved testing of
98 constructor/destructor inlining warnings. Fixes RT #47119.
100 0.86 Tue, Jun 16, 2009
102 - If you redefined a subroutine at runtime and then wrapped it
103 with a method modifier, the modifier could in some cases wrap
104 the original version of the subroutine. Fixes RT #46957.
107 - make_immutable issues a warning instead of overriding an
108 existing DESTROY method (Dylan William Hardison). Fixes RT
111 0.85 Sat, Jun 6, 2009
112 * Class::MOP::Attribute
113 - Allow default values to be Class::MOP::Methods. (Florian
115 - Test the above. (Rhesa Rozendaal)
116 - Tweak original commit so the intent matches the accepted
117 behavior (Nicholas Perez)
120 - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)
123 - Add direct_subclasses method (Sartak)
124 - Tests for subclasses and direct_subclasses (Sartak)
125 - subname is no longer used unconditionally in add_method, but
126 only if the code reference's name is '__ANON__' (nothingmuch)
127 - Add a hook for _superclasses_updated (Sartak)
130 - Remove long, old warning about possibly outdated modules
133 0.84 Tue, May 12, 2009
135 - Depend on Text::Exception 0.27 to avoid failing tests ond old
139 - Made is_class_loaded a little stricter. It was reporting that
140 a class was loaded if it merely had an @ISA variable in its
141 stash. Now it checks that the @ISA var has elements in it.
142 - Deprecate in_global_destruction and subname re-exporting
146 - Explicitly use Devel::GlobalDestruction and Sub::Name
149 * Class::MOP::Package
150 - Disable prototype mismatch warnings for add_package_symbol.
153 - Add test for finding methods from $meta->name->meta before immutable,
156 0.83 Mon, April 27, 2009
158 - Fix segfault when calling get_method_map on a metaclass for an empty
161 0.82_02 Fri, April 24, 2009
162 * Class::MOP::Method::Inlined
163 - Don't inline if the expected method is not defined at all (happens with
164 e.g. Moose::Object::_new is the expected method due to an overridden
167 - Some tests were trying to load Class::MOP::Immutable, which
168 was removed in 0.82_01.
170 0.82_01 Thu, April 23, 2009
171 * Class::MOP::Immutable (and others)
172 - Refactor the immutability system to use a pre-defined class
173 for the immutable metaclass of Class::MOP::Class::Immutable::$class
174 - Rather than generating methods into this class every time, use
175 a Trait (basic mixin) to supply the cached methods
176 - Remove the hack that returns the mutable metaclass for
177 metacircularity in order to provide consistent meta-metaclasses
178 for the Moose compatibility handling code
179 (mst broke it, nothingmuch fixed it)
181 0.82 Mon, April 20, 2009
183 - The deprecation wrappers for some renamed methods were not
184 passing arguments to the new method. (nothingmuch)
186 * Class::MOP::Immutable
187 - Warn during immutablization if the local class provides its own
188 constructor, to parallel the warning in Moose when a superclass
189 provides its own constructor (doy)
191 0.81 Tue, April 7, 2009
194 * Class::MOP::Instance
195 * Class::MOP::Attribute
196 * Class::MOP::Method::Accessor
197 * Class::MOP::Method::Constructor
198 - Include stack traces in the deprecation warnings introduced in
199 0.80_01. (Florian Ragwitz)
202 - Avoid c compiler warnings by declaring some unused function
203 arguments. (Florian Ragwitz)
205 0.80_01 Sun, April 5, 2009
207 - Make sure to preserve any compiler flags already defined in
208 Config.pm. Patch by Vincent Pit. RT #44739.
210 * Many methods have been renamed with a leading underscore, and a
211 few have been deprecated entirely. The methods with a leading
212 underscore are consider "internals only". People writing
213 subclasses or extensions to Class::MOP should feel free to
214 override them, but they are not for "public" use.
217 - construct_class_instance => _construct_class_instance (use new_object)
218 - construct_instance => _construct_instance (use new_object)
219 - check_metaclass_compatibility => _check_metaclass_compatibility
220 - create_meta_instance => _create_meta_instance (use get_meta_instance)
221 - clone_instance => _clone_instance (use clone_object)
222 - compute_all_applicable_methods is deprecated, use get_all_methods
223 - compute_all_applicable_attributes is deprecated, use get_all_attributes
225 - Class::MOP::Instance
226 - bless_instance_structure is deprecated and will be removed
230 - create has been renamed to _instantiate_module. This method
231 does not construct an object, it evals some code that
232 creates the relevant package in Perl's symbol table.
234 - Class::MOP::Method::Accessor
235 - initialize_body => _initialize_body (this is always called
236 when an object is constructed)
237 - /(generate_.*_method(?:_inline)?)/ => '_' . $1
239 - Class::MOP::Method::Constructor
240 - initialize_body => _initialize_body (this is always called
241 when an object is constructed)
242 - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
243 - attributes => _attributes
244 - meta_instance => _meta_instance
246 0.80 Wed, April 1, 2009
248 - Call user_class->meta in fewer places, with the eventual goal
249 of allowing the user to rename or exclude ->meta
250 altogether. Instead uses Class::MOP::class_of. (Sartak)
253 - New class_of function that should be used to retrieve a
254 metaclass. This is unlike get_metaclass_by_name in that it
255 accepts instances, not just class names. (Sartak)
258 - load_first_existing_class didn't actually load the first
259 existing class; instead, it loaded the first existing and
260 compiling class. It now throws an error if a class exists (in
261 @INC) but fails to compile. (hdp)
265 - we had some semi-buggy code that purported to provide a
266 HAS_ISAREV based on whether mro had get_isarev (due to an
267 oversight, it always returned 1). Since mro and MRO::Compat
268 have always had get_isarev, HAS_ISAREV was pointless. This
269 insight simplified the subclasses method by deleting the
270 pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)
272 0.79 Fri, March 29, 2009
273 * No changes from 0.78_02.
275 0.78_02 Thu, March 26, 2009
277 * Class::MOP::Immutable
278 - A big backwards-incompatible refactoring of the Immutable API,
279 and the make_immutable/make_mutable pieces of the Class
280 API. The core __PACKAGE__->meta->make_immutable API remains
281 the same, however, so this should only affect the most
285 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
286 has been fixed to be backwards compatible with 5.8.x.
289 - Add a hook for rebless_instance_away (Sartak)
290 - Use blessed instead of ref to get an instance's class name
291 in rebless_instance. (Sartak)
293 0.78_01 Wed, March 18, 2009
295 - Revised and reorganized all of the API documentation. All
296 classes now have (more or less) complete API documentation.
299 * Class::MOP::Instance
300 - Reblessing into a package that supports overloading wasn't
301 properly adding overload magic to the object due to a bug
302 in (at least) 5.8.8. We now use $_[1] directly which seems
303 to set the magic properly. (Sartak)
305 * Class::MOP::Attribute
306 - The process_accessors method is now private. A public alias
307 exists (and will stick around for a few releases), but it
308 warns that calling the public method is deprecated.
310 * Class::MOP::Method::Generated
311 - Removed the new and _new methods, since this is an abstract
312 base class, and all existing subclasses implement their own
316 - Stop is_class_loaded from thinking a class is loaded if it
317 only has an empty GV (Florian Ragwitz).
318 - Add a test for this (Yappo).
319 - Refactor get_all_package_symbols to allow short-circuiting
321 - Use this in is_class_loaded (Florian Ragwitz).
322 - Stop segfaulting when trying to get the name from a sub that's
323 still being compiled (Florian Ragwitz).
324 - Add tests for this (Florian Ragwitz).
325 - Prefix all public symbols with "mop_" (Florian Ragwitz).
326 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
327 - Simplify creating simple xs reader methods (Florian Ragwitz).
328 - Make everything compile with c++ compilers (Florian Ragwitz).
329 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
332 - Remove optional test plans for tests depending on Sub::Name as
333 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
336 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
338 0.78 Mon, February 23, 2009
339 * No changes from 0.77_01
341 0.77_01 Sun, February 22, 2009
343 - This package now requires its XS components. Not using
344 Sub::Name lead to different behavior and bugginess in the pure
345 Perl version of the code. A Moose test would fail when run
346 against the pure Perl version of this code.
348 * Class::MOP::Instance
349 - The inline_* methods now quote attribute names themselves, and
350 don't expect to receive a quoted value.
353 0.77 Sat, February 14, 2009
355 - Avoid assertion errors on debugging perls in is_class_loaded
359 - Fixed various corner cases where is_class_loaded incorrectly
360 returned true for a class that wasn't really loaded. (Dave
364 - Add get_all_method_names (Sartak)
365 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
367 * Class::MOP::Package
368 - Disable deprecated get_all_package_symbols in list
369 context. (Florian Ragwitz)
372 - Make sure we generate a BSD-compatible Makefile (Florian
376 - The misspelled "check_metaclass_compatability" method we've
377 kept around for backwards compat_i_bility will be removed in a
378 near future release. You've been warned.
380 0.76 Thu, January 22, 2009
381 * Class::MOP::Method::Generated
382 - Added new private methods to support code generation, which
383 are being used by Moose and can be used by MooseX
385 - Generated methods are now generated with a #line directive
386 reflecting the source of the generated method. (nothingmuch)
389 - Clarified documentation of methods that return
390 Class::MOP::Method objects. (doy)
393 - Clarified documentation of the metaclass cache methods. (Sartak)
396 - Add test showing how the xs Class::MOP::is_class_loaded can
397 be made to operate differently to the pure perl version (t0m)
399 0.75 Wed, December 31, 2008
401 - A class that was made immutable and then mutable could end up
402 sharing an immutable transformer object
403 (Class::MOP::Immutable) with other classes, leading to all
404 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
406 0.74 Tue, December 25, 2008
408 - Add an xs implementation of Class::MOP::is_class_loaded (closes
409 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
410 - Changed internals to make prehashing of hash keys easier and less
411 error-prone. (Florian Ragwitz)
413 - Fix documentation to show that around modifiers happen on both
414 sides of the modified method. (Dave Rolsky)
416 0.73 Tue, December 16, 2008
418 - Don't use Perl_mro_meta_init. It's not part of the public perl
419 api. Fixes failures to build on Win32 (RT #41750). (Florian
421 * t/082_get_code_info.t
422 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
423 munger anonymous subs when under -d and so making the tests
424 succeed in that case.
426 0.72 Mon, December 8, 2008
427 * Class::MOP::Package
428 - Pass options to _new, so subclass' attributes can be
431 - In the docs, indicate that package_name and name are required
432 when calling ->wrap (Stefan O'Rear)
434 0.71_02 Fri, December 5, 2008
435 * Class::MOP::Immutable
436 - Added a new attribute, inlined_constructor, which is true if
437 the constructor was inlined.
438 * Class::MOP::Package
439 - Make get_all_package_symbols return a hash ref in scalar
440 context and deprecate calling it in list context with a
441 warning. (Florian Ragwitz)
443 - Various improvements and refactoring, making things more robust and
444 easier to maintain. (Florian Ragwitz)
446 0.71_01 Wed, December 3, 2008
448 - Add an "execute" method to invoke the body so
449 we can avoid using the coderef overload (Sartak)
450 * Class::MOP::Immutable
451 - When we memoize methods, get their results lazily
452 to remove some compile-time cost (Sartak)
453 - Small speedup from eliminating several method
456 - Some small internal tweaks to try to reduce the number of
457 times we call get_method_map when bootstrapping the MOP. This
458 might make loading Class::MOP (and Moose) a little
459 faster. (Dave Rolsky)
460 - Implemented an optional XS version of get_method_map. Mostly
461 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
462 help form Florian Ragwitz. (Dave Rolsky)
463 - Make the behaviour of of get_all_package_symbols (and
464 therefore get_method_map) consistent for stub methods. Report
465 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
467 0.71 Wed November 26, 2008
470 - Actual package creation has moved upward from
471 Class to Module so that Moose roles can share
474 0.70_01 Mon, November 19, 2008
476 - Fixes for failures with blead (Florian Ragwitz)
477 - Silenced compiler warnings (Florian Ragwitz)
479 0.70 Fri, November 14, 2008
481 - Fixed an odd corner case where the XS version of
482 get_all_package_symbols could cause a segfault. This only
483 happened with inlined constants in Perl 5.10.0 (Florian
486 0.69 Fri, November 7, 2008
487 * Class::MOP::Method::Wrapped
488 - Added introspection methods for method modifiers (Dave Rolsky)
491 0.68 Fri October 24, 2008
493 - Make load_class require by file name instead of module name.
494 This stops confusing error messages when loading '__PACKAGE__'.
496 - Add load_one_class_of function to enable you to load one of a
497 list of classes, rather than having to call load_class multiple
498 times in an eval. (t0m)
500 0.67 Tue October 14, 2008
502 - Call a method on the class after setting the superclass list
503 so that we can get Perl to detect cycles before MRO::Compat
504 spirals into an infinite loop (sartak)
505 - Reported by Schwern, [rt.cpan.org #39001]
506 - In create(), pass unused options on to initialize()
507 - added test for this
509 0.66 Sat September 20, 2008
510 !! This release has an incompatible change regarding !!
511 introspection of a class's method with Class::MOP::Class !!
514 - We (us maintainers) now run all tests with XS and then without
515 XS, which should help us catch skew between the XS/pure Perl
519 ! The alias_method method has been deprecated. It now simply
520 calls add_method instead. There is no distinction between
521 aliased methods and "real" methods.
523 This means that methods added via alias_method now show up as
524 part of the class's method list/map. This is a backwards
525 incompatible change, but seems unlikely to break any
526 code. Famous last words. (Dave Rolsky)
529 - Fixed the spelling of "compatibility", but we still have a
530 "check_metaclass_compatability" method for backwards
533 0.65 Mon September 1, 2008
534 For those not following the series of dev releases, the changes
535 from 0.64 from 0.65 can mostly be summed up as a lot performance
536 improvements by nothingmuch, including new optional XS versions of
537 some methods. Also, Class::MOP now works _without_ any XS modules,
538 for sad systems without a compiler.
541 - Added name and package_name XS accessors, and make sure all
542 the XS and Perl versions work the same way. (Dave Rolsky)
545 - The XS versions of various methods just returned undef when
546 called class methods, rather than dying like the pure Perl
547 versions. (Dave Rolsky)
549 0.64_07 Fri August 29, 2008
551 - Silenced warnings that managed to break Moose tests when XS
552 was loaded. (Dave Rolsky)
553 - Some XS versions of methods were ignored because of typos in
554 MOP.xs. (Dave Rolsky)
556 0.64_06 Mon August 25, 2008
557 * Class::MOP (MOP.xs)
558 - Another MS VC++ fix, cannot declare a variable in the middle
559 of a scope (Taro Nishino).
561 0.64_05 Sun August 24, 2008
563 - None of the dev releases actually loaded the XS properly, but
564 we silently fell back to the pure Perl version of the
567 * Class::MOP (MOP.xs)
568 - Replaced some code that used functions not available on Visual
569 C++ with some Perl XS API bits (Dave Rolsky).
571 0.64_04 Sat August 23, 2008
573 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
575 * pod.t and pod_coveraget.t
576 - These are no longer shipped with the tarball because of bogus
577 failures from CPAN testers. (Dave Rolsky)
579 0.64_03 Thu August 21, 2008
580 * Class::MOP::Package
581 - Some (legit) code was misparsed by earlier 5.8.x
582 releases. (nothingmuch)
585 - Fix a constant in void context warning (nothingmuch)
587 0.64_02 Thu August 21, 2008
588 * Makefile.PL and Class::MOP
589 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
592 - Add missing prereqs that got lost in the switch away from
595 * Class::MOP::Instance
596 - New method - get_all_attributes (nothingmuch)
598 0.64_01 Wed August 20, 2008
600 - We now check to see if you have a compiler. If you don't, the
601 module installs without some XS bits, but will work the same
602 as with XS. This should make it easier to install on platforms
603 without a compiler (like Windows). (Dave Rolsky)
606 - Perl 6 style attribute naming replaced with sane style ('methods', not
607 '%!methods'). These changes should not impact any existing API uses.
611 - Quite a number of optimizations based on profiling, including
612 allowing constructors to take hash references instead of
613 hashes, duplicating some frequently used code in XS, and
614 making constructors immutable. These changes should not impact
615 any existing API uses. (nothingmuch)
618 - Constructors now respect the meta attributes of their subclasses,
619 facilitating MOP extensibility. More related changes will happen in the
620 next several releases. (nothingmuch)
623 - New method - get_all_methods, replaces the deprecated
624 compute_all_applicable_methods. get_all_attributes provided for
625 consistency (nothingmuch)
626 - New method - wrap_method was refactored out of get_method_map
628 - New API for meta instance invalidation - invalidate_meta_instance,
629 invalidate_meta_instances, add_dependent_meta_instance,
630 remove_dependent_meta_instance, called automatically when attribute
631 definitions change and allows notification of dependent subclasses.
634 0.64 Sun August 3, 2008
635 * Class::MOP::Immutable
636 - fixing subtle edge case in immutable when you
638 - clean up option processing (nothingmuch)
640 * Class::MOP::Instance
641 - inlined initialize slot didn't match
642 non-inlined (nothingmuch)
644 0.63 Mon July 7, 2008
646 - load_class will initialize a metaclass even if
647 the class is already loaded (sartak)
648 - load_class now returns the metaclass instance
649 instead of just 1 (sartak)
652 - better error messages (sartak and Dave Rolsky)
654 0.62 Wed June 18, 2008
655 - in is_class_loaded, recognize scalar references (as opposed to globs) in
656 the symbol table as methods (these are optimized constant subs)
658 0.61 Fri. June 13, 2008
659 - Okay, lets give this another try and see if PAUSE
660 recognizes it correct this time.
662 0.60 Thurs. Jun 12, 2008
663 - Fixed a version number issue by bumping all modules
666 0.59 Thurs. Jun 12, 2008
667 !! Several fixes resulting in yet another 25-30% speedup !!
670 - now stores the instance of the instance
671 metaclass to avoid needless recomputation
672 and deletes it when the cache is blown
673 - introduce methods to query Class::MOP::Class for
674 the options used to make it immutable as well as
675 the proper immutable transformer. (groditi)
677 * Class::MOP::Package
678 - {add, has, get, remove}_package_symbol all
679 now accept a HASH ref argument as well as the
680 string. All internal usages now use the HASH
684 - MOP.xs does sanity checks on the coderef
686 - is_class_loaded check now uses code that
687 was improved in Moose's ClassName type
689 - nonsensical (undef, empty, reference) class
690 names now throw a more direct error in
692 - tests for this and other aspects of
698 Class::MOP::Method::Wrapped
699 Class::MOP::Attribute
700 - switched usage of reftype to ref because
703 0.58 Thurs. May 29, 2008
704 (late night release engineering)--
706 - fixing the version is META.yml, no functional
707 changes in this release
709 0.57 Wed. May 28, 2008
710 !! Several speedups resulting in 20-25% speedups !!
711 || (thanks to konobi, groditi, mst & CataMoose) !!
714 - made get_method_map use list_all_package_symbols
715 instead of manually grabbing each symbol
716 - streamlining &initialize somewhat, since it gets
719 * Class::MOP::Package
720 - made {get, has}_package_symbol not call
722 - inlining a few calls to &name with
723 direct HASH access key access
724 - added get_all_package_symbols to fetch
725 a HASH of items based on a type filter
726 similar to list_all_package_symbols
727 - added tests for this
730 Class::MOP::Method::Constructor
731 Class::MOP::Method::Generated
732 Class::MOP::Method::Accessor
733 - added more descriptive error message to help
734 keep people from wasting time tracking an error
735 that is easily fixed by upgrading.
737 * Class::MOP::Immutable
738 - Don't inline a destructor unless the user actually
740 - added tests for this
742 0.56 Saturday, May 24, 2008
744 - we now get the &check_package_cache_flag
745 function from MRO::Compat
746 - All XS based functionality now has a
747 Pure Perl alternative
748 - the CLASS_MOP_NO_XS environment variable
749 can now be used to force non-XS versions
752 * Class::MOP::Attribute
753 - add has_read_method and has_write_method
754 - get_{read,write}_method_ref now wraps the
755 anon-sub ref in the method metaclass when
757 - added tests for this
759 * Class::MOP::Immutable
760 - added the ability to "wrap" methods when
761 making the class immutable
764 - now handling the edge case of ->meta->identifier
765 dying by wrapping add_package_symbol to specifically
766 allow for it to work.
767 - added tests for this
769 * Class::MOP::Attribute
771 Class::MOP::Immutable
772 - any time a method meta object is constructed
773 we make sure to pass the correct package and
774 method name information
777 Class::MOP::Method::Wrapped
778 Class::MOP::Method::Generated
779 Class::MOP::Method::Accessor
780 Class::MOP::Method::Consructor
781 - the &wrap constructor method now requires that a
782 'package_name' and 'name' attribute are passed. This
783 is to help support the no-XS version, and will
784 throw an error if these are not supplied.
785 - all these classes are now bootstrapped properly
786 and now store the package_name and name attributes
789 ~ Build.PL has been removed since the
790 Module::Install support has been removed
792 0.55 Mon. April 28, 2008
793 - All classes now have proper C3 MRO support
794 - added MRO::Compat as a dependency to allow
795 for the C3 MRO support to Just Work in all
799 - rebless_instance now returns the instance
800 it has just blessed, this is mostly to
802 - set the attr correctly in rebless_instance
803 when it has no init_arg
804 - tweaked &linear_isa and &class_precedence_list
805 to support c3 classes.
807 0.54 Fri. March, 14, 2008
810 - making sure that load_class never gets
811 passed a value from @_ or $_ to squash
812 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
815 - make_{immutable,mutable} now return 1
817 - improved error handling in ->create method
818 - rebless_instance now takes extra params which
819 will be used to populate values
820 - added tests for this
823 - localizing the Data::Dumper configurations so
824 that it does not pollute others (RT #33509)
830 Class::MOP::Attribute
831 - these classes no longer define their own ->meta,
832 but instead just inherit from Class::MOP::Object
834 * Class::MOP::Instance
835 Class::MOP::Immutable
836 - these classes now inherit from Class::MOP::Object
839 - fixed the filename length on several
840 test files so we install on VMS better
842 - fixed incorrect use of catdir when it
843 should be catfile (RT #32385)

846 ~~ several doc. fixes and updates ~~
849 Class::MOP::Method::Constructor

851 - making init_arg accept an undefined value
852 to indicate that no constructor args can
853 be passed (thanks to nothingmuch)
854 - added tests for this
855 - added attribute initializer attribute (rjbs)
858 - making this use the new init_arg => undef
859 feature instead of the silly hack from
860 before (thanks to nothingmuch)
862 0.52 Tues. Jan. 22, 2008
864 - fixed bug in rebless_instance
867 * Class::MOP::Method::Constructor
868 - removed assumptions about the existence of
871 0.51 Mon. Jan. 14, 2008
872 ~~~ some misc. doc. fixes ~~~
873 ~~ updated copyright dates ~~
876 - now sets the IS_RUNNING_ON_5_10
877 constant so that we can take advantage
878 of some of the nice bits of 5.10
881 - uses the IS_RUNNING_ON_5_10 flag to
882 optimize the &linearized_isa method
883 and avoid the hack/check for circular
884 inheritence in &class_precedence_list
885 - added rebless_instance method (Sartak)
886 - added tests for this
888 * Class::MOP::Immutable
889 - the immutable class now keeps track of
890 the transformer which immutablized it
892 * Class::MOP::Instance
893 - added rebless_instance_structure method (Sartak)
894 - added tests for this
896 0.50 Fri. Dec. 21, 2007

899 transformation arguments are saved
901 - added tests for this
903 * Class::MOP::Immutable
904 - fixed a bug (see above)
906 * Class::MOP::Attribute
909 0.49 Fri. Dec. 14, 2007
910 !! Class::MOP now loads 2 x faster !!
911 !! with XS speedups (thanks konobi) !!
914 - removed the dependency on B
915 - added two XS functions (thanks konobi)
916 - get_code_info($code) which replaces all
917 the B fiddling we were doing with
918 faster/leaner XS level fiddling
919 - check_package_cache_flag($pkg_name) which
920 returns the PL_sub_generation variable to
921 be used to help manage method caching.
924 In 5.10 or greater this will actually
925 use the mro::get_pkg_gen instead to give
926 even more accurate caching information.
927 blblack++ for that stuff :)
930 - added the &subclasses method (thanks rlb)
931 - added the update_package_cache_flag and
932 reset_package_cache_flag which help keep
933 track of when we need to re-fetch the
935 - Several small improvements to take advantage
936 of the new method map caching features
938 0.48 Mon. Nov. 26, 2007
939 * Class::MOP::Attribute
940 - fixed get_read/write_method to handle the

943 - added more tests for this
945 0.47 Sat. Nov. 24, 2007
946 * Class::MOP::Attribute

948 - added more tests for this
950 0.46 Fri. Nov. 23, 2007
952 - added the linearized_isa method instead of constantly
953 pruning duplicate classes (this will be even more
954 useful in the 5.10-compat version coming soon)
956 * Class::MOP::Attribute
957 - added the get_read_method_ref and get_write_method_ref
958 methods which allow you to retrieve a CODE ref which
959 can always be used to read or write an attribute.
961 0.45 Thurs. Nov. 13, 2007
962 * Class::MOP::Attribute
963 - Fix error message on confess (groditi)
965 0.44 Thurs. Nov. 13, 2007

989 - removed the relevant attributes
991 * Class::MOP::Method::Constructor
992 - fixed the cached values we had to be more sane
993 - made this a subclass of Class::MOP::Method::Generated
994 - fixed generated constructor so it properly handles
996 - added tests for this
997 - added the option to allow for both inlined and
998 non-inlined constructors.
999 - Update inlined methods for builder and predicate changes (groditi)
1001 * Class::MOP::Method::Generated
1002 - added this class as an abstract base for the
1003 Class::MOP::Method::{Constructor,Accessor} classes
1004 - added tests for this
1007 - Alter tests (005, 014 020, 021) for new builder addition (groditi)

1017 - alter symbol table handling to deal with 5.8.x and 5.9.x
1020 - Get rid of the crappy workaround from 0.40/41
1022 0.41 Sun. July 15, 2007
1024 Arghh!!! My TODO test didn't work, so I handle
1025 it manually now so that people can use this
1026 with 5.9.5/bleadperl without issue.
1028 0.40 Tues, July 3, 2007
1030 ~ marked a test in 003_methods.t as TODO
1031 for perl 5.9.5 (this test is irrelvant to
1032 the module functioning on 5.9.5 for the most
1035 0.39 Mon. June 18, 2007
1036 * Class::MOP::Immutable
1037 - added make_metaclass_mutable + docs (groditi)
1038 - removed unused variable
1039 - added create_immutable_transformer
1040 necessary for sane overloading of immutable behavior
1041 - tests for this (groditi)
1044 - Immutability can now be undone,
1045 added make_mutable + tests + docs (groditi)
1046 - Massive changes to the way Immutable is done
1047 for details see comments next to make_immutable
1048 This fixes a bug where custom metaclasses broke
1049 when made immutable. We are now keeping one immutable
1050 metaclass instance per metaclass instead of just one
1051 to prevent isa hierarchy corruption. Memory use will go
1052 up, but I suspect it will be neglible.
1053 - New tests added for this behavior. (groditi)
1055 0.38 Thurs. May 31, 2007
1056 ~~ More documentation updates ~~
1058 * Class::MOP::Package

1065 thanks to groditi for this code, tests
1067 - added tests and POD for this
1070 - fixed RT issue #27329, clone object now
1071 handles undef values correctly.
1072 - added tests for this
1073 - Corrected anon-class handling so that they
1074 will not get reaped when instances still
1075 exist which need to reference them. This is
1076 the correct behavior, hopefully this is an
1077 obscure enough feature that there are not too
1078 many work arounds out in the wild.
1079 - added tests for this by groditi
1080 - updated docs to explain this
1083 - load custom metaclasses automatically (thanks groditi)
1084 - added tests for this behavior
1086 0.37 Sat. March 10, 2007

1095 avoid setting off bool-overloads (found by Carl Franks)
1099 - bad name in a test, causing meaningless failuress.
1104 ~~ GLOBAL CHANGES ~~
1105 - All attribute names are now consistent and follow Perl 6
1106 style (prefixed with the sigil, and ! as the twigil for
1107 private attrs). This should not affect any code, unless
1108 you broke encapsulation, in which case, it is your problem
1111 !! Class::MOP::Class::Immutable has been removed
1113 * Class::MOP::Method::Constructor
1114 - this has been moved out of Class::MOP::Class::Immutable
1115 and is a proper subclass of Class::MOP::Method now.
1118 - this module now uses Class::MOP::Immutable for the
1119 immutable transformation instead of
1120 Class::MOP::Class::Immutable.
1122 + Class::MOP::Immutable
1123 - this module now controls the transformation from a mutable
1124 to an immutable version of the class. Docs for this will
1125 be coming eventually.
1128 0.36 Sun. Nov. 5, 2006
1130 - added a few 'no warnings' lines to keep annoying
1131 (and meaningless) warnings from chirping during
1135 - some more bootstrapping is now done on the new
1138 * Class::MOP::Class::Immutable
1140 - constructor generation is now handled by
1141 the Class::MOP::Method::Constructor class
1143 * Class::MOP::Method::Constructor
1144 - created this to handle constructor generation
1145 in Class::MOP::Class::Immutable
1147 * Class::MOP::Attribute
1149 - attributes now delegate to the
1150 Class::MOP::Method::Accessor to generate
1153 * Class::MOP::Method::Accessor
1154 - all accessor generation functions from
1155 Class::MOP::Attribute have been moved here

1160 - initial prototype of a class browser, more
1161 on this to come. Comments and patches are

1166 re-generated in the bootstrap, instead
1167 they are aliased from the originals

1171 - adjusted tests for this
1172 - added the Class::MOP::Instance attributes

1179 - adjusted tests to compensate
1180 - adjusted docs for this
1183 - changed how methods are dealt with to
1184 encapsulate most of the work into the
1185 &get_method_map method
1186 - made several adjustments for the change
1187 in Class::MOP::Method
1188 - &add_attribute now checks if you are adding
1189 a duplicate name, and properly removes the
1190 old one before installing the new one
1191 - added tests for this
1192 - adjusted docs for this
1194 * Class::MOP::Class::Immutable
1195 - added caching of &get_method_map
1196 - fixed issue with &get_package_symbol
1197 - cleaned up the methods that die (patch by David Wheeler)

1201 &list_all_package_symbols
1203 0.34 Sat. Aug. 26, 2006
1205 - added the %:methods attribute, which like
1206 the $:version and such just actually goes
1207 to the symbol table to get it's stuff.
1208 However, it makes the MOP more complete.
1210 - The &create method now requires that all
1211 but the package name now is passed in as
1212 named parameters. See docs for more info.
1213 - updated docs and tests for this
1215 * Class::MOP::Object
1216 - added &dump method to easily Data::Dumper

1238 are no longer allowed for defaults
1239 - added tests for this
1241 * Class::MOP::Package
1242 - fixed an issue with perl 5.8.1 and how it deals
1243 with symbol tables. The namespace hash is now
1244 always reloaded from the symbol table.
1246 ~ lots of misc. documentation cleanup
1248 0.32 Sat. Aug. 12, 2006
1249 + added Class::MOP::Object so that the
1250 metamodel is more complete (and closer
1251 to what Perl 6 will probably be).

1255 the primary gateway between the metaclass
1256 and the Perl 5 symbol table
1257 - added many tests for this
1258 - this class is now a subclass of
1260 - added some tests to reflect this

1264 use Class::MOP::Package methods instead
1266 * Class::MOP::Module
1267 - adding the $:version attribute in the bootstrap
1268 so that Module has a version as an attribute
1269 - see comment in Class::MOP for details
1270 - added the $:authority attribute to this module
1271 as well as an &identifier method, to bring us
1272 ever closer to Perl 6 goodness
1273 - I have added $AUTHORITY to all the modules
1274 - added tests for this

1290 anywhere within the class hierarchy
1292 * Class::MOP::Attribute
1293 - added &set_value and &get_value for getting
1294 the value of the attribute for a particular
1297 0.30 Wed. July 5, 2006
1298 ---------------------------------------
1299 This is the first version of Class::MOP
1300 to introduce the immutable features which
1301 will be used for optimizating the MOP.
1302 This support should still be considered
1303 experimental, but moving towards stability.
1304 ---------------------------------------
1306 * Created Class::MOP::Class::Immutable
1308 * Created the Class::MOP::Package and
1309 Class::MOP::Module classes to more
1310 closely conform to Perl 6's meta-model
1313 - now inherits from Class::MOP::Module
1314 - several methods moved to ::Module and
1315 ::Package and now inherited
1316 - added tests for this
1318 * Class::MOP::Instance
1319 - added an is_inlinable method to allow other
1320 classes to check before they attempt to optimize.
1321 - added an inline_create_instance to inline
1322 instance creation (of course)
1325 - the Class::MOP::Class::*_package_variable
1326 methods are all now methods of Class::MOP::Package
1327 and called *_package_symbol instead. This is
1328 because they are now more general purpose symbol
1329 table manipulation methods.
1331 0.29_02 Thurs. June 22, 2006
1332 ++ DEVELOPER RELEASE ++
1334 - small change in &create so that it behaves

1391 of the attribute itself, and construct_instance now
1392 delegates appropriately
1394 * Class::MOP::Attribute

1396 of the attribute itself, so we added a method for it
1397 called initialize_instance_slot

1426 0.21 Wed. March 15, 2006
1428 - fixed issue where metaclasses are reaped from

1444 before, after and around modifiers
1445 - added tests and docs for this feature

1455 - &add_around_method_modifier
1456 - added tests and docs for these

1458 equivalent of SUPER::method_name
1460 0.12 Thurs. Feb 23, 2006
1461 - reduced the dependency on B, no need to always
1465 - added docs to the C3 method dispatch order test
1466 - fixed missing Algorithm::C3 dependency by making
1467 the test skip if it is not installed
1469 0.11 Mon Feb. 20, 2006
1471 - added example of changing method dispatch order to C3
1474 - changed how clone_instance behaves, it now only does a
1475 shallow clone (see docs for more details)
1476 - added docs and tests
1478 0.10 Tues Feb. 14, 2006
1479 ** This release was mostly about writing more tests and
1480 cleaning out old and dusty code, the MOP should now
1481 be considered "ready to use".
1483 - adding more tests to get coverage up a little higher,
1484 mostly testing errors and edge cases.
1485 - test coverage is now at 99%
1488 - no longer optionally exports to UNIVERSAL::meta or
1489 creates a custom metaclass generator, use the
1490 metaclass pragma instead.
1493 - fixed a number of minor issues which came up in the
1494 error/edge-case tests
1496 * Class::MOP::Attribute
1497 - fixed a number of minor issues which came up in the
1498 error/edge-case tests
1501 - fixing the AttributesWithHistory example, it was broken.
1503 0.06 Thurs Feb. 9, 2006
1505 - adding new metaclass pragma to make setting up the
1506 metaclass a little more straightforward
1509 - clean up bootstrapping to include more complete
1510 attribute definitions for Class::MOP::Class and
1511 Class::MOP::Attribute (accessors, readers, writers,
1512 etc.) ... it is redundant, but is useful meta-info
1516 - fixing minor meta-circularity issue with &meta, it
1517 is now more useful for subclasses
1518 - added &get_attribute_map as an accessor for the
1519 hash of attribute meta objects
1520 - &compute_all_applicable_attributes now just returns
1521 the attribute meta-object, rather than the HASH ref
1522 since all the same info can be gotten from the
1523 attribute meta-object itself
1524 - updated docs & tests to reflect
1525 - added &clone_instance method which does a deep clone
1526 of the instance structure created by &construct_instance
1527 - added docs & tests for this
1528 - added Clone as a dependency
1529 - added &new_object and &clone_object convience methods to
1530 return blessed new or cloned instances
1531 - they handle Class::MOP::Class singletons correctly too
1532 - added docs & tests for this
1533 - cleaned up the &constuct_class_instance so that it behaves
1534 more like &construct_instance (and managed the singletons too)
1535 - added the &check_metaclass_compatibility method to make sure
1536 that metaclasses are upward and downward compatible.
1537 - added tests and docs for this
1540 - adjusting code to use the &Class::MOP::Class::meta
1542 - adjusting code to use the metaclass pragma
1544 0.05 Sat Feb. 4, 2006
1546 - added the &attribute_metaclass and &method_metaclass
1547 attributes which contain a metaclass name to use for
1548 attributes/methods respectively
1551 - bootstrap additional attributes for Class::MOP::Class
1554 - adjusted the example code and tests to use the new
1555 &attribute_metaclass feature of Class::MOP::Class
1556 - added new example:
1559 0.04 Fri Feb. 3, 2006
1561 - some documentation suggestions from #perl6
1563 * Class::MOP::Attribute
1564 - improved error messages
1567 - added new examples:
1568 - AttributesWithHistory
1569 - ClassEncapsultedAttributes
1571 0.03 Fri Feb. 3, 2006
1572 - converted to Module::Build instead of EU::MM
1574 * Class::MOP::Attribute
1575 - refactored method generation code
1576 - attributes are now associated with class directly
1579 - refactored the InsideOut example to take advantage
1580 of the Class::MOP::Attribute refactoring
1581 - changed example files to .pod files and hide thier
1582 package names from PAUSE (I don't want to own these
1583 namespaces really, they are just examples)
1585 0.02 Thurs Feb. 2, 2006
1586 - moving examples from t/lib/* to examples/*
1587 - adding POD documentation to the examples
