1 Revision history for Perl extension Class-MOP.
3 0.78_02 Thu, March 26, 2009
5 * Class::MOP::Immutable
6 - A big backwards-incompatible refactoring of the Immutable API,
7 and the make_immutable/make_mutable pieces of the Class
8 API. The core __PACKAGE__->meta->make_immutable API remains
9 the same, however, so this should only affect the most
13 - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
14 has been fixed to be backwards compatible with 5.8.x.
17 - Add a hook for rebless_instance_away (Sartak)
18 - Use blessed instead of ref to get an instance's class name
19 in rebless_instance. (Sartak)
21 0.78_01 Wed, March 18, 2009
23 - Revised and reorganized all of the API documentation. All
24 classes now have (more or less) complete API documentation.
27 * Class::MOP::Instance
28 - Reblessing into a package that supports overloading wasn't
29 properly adding overload magic to the object due to a bug
30 in (at least) 5.8.8. We now use $_[1] directly which seems
31 to set the magic properly. (Sartak)
33 * Class::MOP::Attribute
34 - The process_accessors method is now private. A public alias
35 exists (and will stick around for a few releases), but it
36 warns that calling the public method is deprecated.
38 * Class::MOP::Method::Generated
39 - Removed the new and _new methods, since this is an abstract
40 base class, and all existing subclasses implement their own
44 - Stop is_class_loaded from thinking a class is loaded if it
45 only has an empty GV (Florian Ragwitz).
46 - Add a test for this (Yappo).
47 - Refactor get_all_package_symbols to allow short-circuiting
49 - Use this in is_class_loaded (Florian Ragwitz).
50 - Stop segfaulting when trying to get the name from a sub that's
51 still being compiled (Florian Ragwitz).
52 - Add tests for this (Florian Ragwitz).
53 - Prefix all public symbols with "mop_" (Florian Ragwitz).
54 - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
55 - Simplify creating simple xs reader methods (Florian Ragwitz).
56 - Make everything compile with c++ compilers (Florian Ragwitz).
57 - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
60 - Remove optional test plans for tests depending on Sub::Name as
61 we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
64 - Rebuild all c code if mop.h has changed (Florian Ragwitz)
66 0.78 Mon, February 23, 2009
67 * No changes from 0.77_01
69 0.77_01 Sun, February 22, 2009
71 - This package now requires its XS components. Not using
72 Sub::Name lead to different behavior and bugginess in the pure
73 Perl version of the code. A Moose test would fail when run
74 against the pure Perl version of this code.
76 * Class::MOP::Instance
77 - The inline_* methods now quote attribute names themselves, and
78 don't expect to receive a quoted value.
81 0.77 Sat, February 14, 2009
83 - Avoid assertion errors on debugging perls in is_class_loaded
87 - Fixed various corner cases where is_class_loaded incorrectly
88 returned true for a class that wasn't really loaded. (Dave
92 - Add get_all_method_names (Sartak)
93 - Add a wrapped_method_metaclass attribute (Florian Ragwitz)
96 - Disable deprecated get_all_package_symbols in list
97 context. (Florian Ragwitz)
100 - Make sure we generate a BSD-compatible Makefile (Florian
104 - The misspelled "check_metaclass_compatability" method we've
105 kept around for backwards compat_i_bility will be removed in a
106 near future release. You've been warned.
108 0.76 Thu, January 22, 2009
109 * Class::MOP::Method::Generated
110 - Added new private methods to support code generation, which
111 are being used by Moose and can be used by MooseX
113 - Generated methods are now generated with a #line directive
114 reflecting the source of the generated method. (nothingmuch)
117 - Clarified documentation of methods that return
118 Class::MOP::Method objects. (doy)
121 - Clarified documentation of the metaclass cache methods. (Sartak)
124 - Add test showing how the xs Class::MOP::is_class_loaded can
125 be made to operate differently to the pure perl version (t0m)
127 0.75 Wed, December 31, 2008
129 - A class that was made immutable and then mutable could end up
130 sharing an immutable transformer object
131 (Class::MOP::Immutable) with other classes, leading to all
132 sorts of odd bugs. Reported by t0m. (Dave Rolsky)
134 0.74 Tue, December 25, 2008
136 - Add an xs implementation of Class::MOP::is_class_loaded (closes
137 RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
138 - Changed internals to make prehashing of hash keys easier and less
139 error-prone. (Florian Ragwitz)
141 - Fix documentation to show that around modifiers happen on both
142 sides of the modified method. (Dave Rolsky)
144 0.73 Tue, December 16, 2008
146 - Don't use Perl_mro_meta_init. It's not part of the public perl
147 api. Fixes failures to build on Win32 (RT #41750). (Florian
149 * t/082_get_code_info.t
150 - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
151 munger anonymous subs when under -d and so making the tests
152 succeed in that case.
154 0.72 Mon, December 8, 2008
155 * Class::MOP::Package
156 - Pass options to _new, so subclass' attributes can be
159 - In the docs, indicate that package_name and name are required
160 when calling ->wrap (Stefan O'Rear)
162 0.71_02 Fri, December 5, 2008
163 * Class::MOP::Immutable
164 - Added a new attribute, inlined_constructor, which is true if
165 the constructor was inlined.
166 * Class::MOP::Package
167 - Make get_all_package_symbols return a hash ref in scalar
168 context and deprecate calling it in list context with a
169 warning. (Florian Ragwitz)
171 - Various improvements and refactoring, making things more robust and
172 easier to maintain. (Florian Ragwitz)
174 0.71_01 Wed, December 3, 2008
176 - Add an "execute" method to invoke the body so
177 we can avoid using the coderef overload (Sartak)
178 * Class::MOP::Immutable
179 - When we memoize methods, get their results lazily
180 to remove some compile-time cost (Sartak)
181 - Small speedup from eliminating several method
184 - Some small internal tweaks to try to reduce the number of
185 times we call get_method_map when bootstrapping the MOP. This
186 might make loading Class::MOP (and Moose) a little
187 faster. (Dave Rolsky)
188 - Implemented an optional XS version of get_method_map. Mostly
189 taken from a patch by Goro Fuji (rt.cpan.org #41080), with
190 help form Florian Ragwitz. (Dave Rolsky)
191 - Make the behaviour of of get_all_package_symbols (and
192 therefore get_method_map) consistent for stub methods. Report
193 and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)
195 0.71 Wed November 26, 2008
198 - Actual package creation has moved upward from
199 Class to Module so that Moose roles can share
202 0.70_01 Mon, November 19, 2008
204 - Fixes for failures with blead (Florian Ragwitz)
205 - Silenced compiler warnings (Florian Ragwitz)
207 0.70 Fri, November 14, 2008
209 - Fixed an odd corner case where the XS version of
210 get_all_package_symbols could cause a segfault. This only
211 happened with inlined constants in Perl 5.10.0 (Florian
214 0.69 Fri, November 7, 2008
215 * Class::MOP::Method::Wrapped
216 - Added introspection methods for method modifiers (Dave Rolsky)
219 0.68 Fri October 24, 2008
221 - Make load_class require by file name instead of module name.
222 This stops confusing error messages when loading '__PACKAGE__'.
224 - Add load_one_class_of function to enable you to load one of a
225 list of classes, rather than having to call load_class multiple
226 times in an eval. (t0m)
228 0.67 Tue October 14, 2008
230 - Call a method on the class after setting the superclass list
231 so that we can get Perl to detect cycles before MRO::Compat
232 spirals into an infinite loop (sartak)
233 - Reported by Schwern, [rt.cpan.org #39001]
234 - In create(), pass unused options on to initialize()
235 - added test for this
237 0.66 Sat September 20, 2008
238 !! This release has an incompatible change regarding !!
239 introspection of a class's method with Class::MOP::Class !!
242 - We (us maintainers) now run all tests with XS and then without
243 XS, which should help us catch skew between the XS/pure Perl
247 ! The alias_method method has been deprecated. It now simply
248 calls add_method instead. There is no distinction between
249 aliased methods and "real" methods.
251 This means that methods added via alias_method now show up as
252 part of the class's method list/map. This is a backwards
253 incompatible change, but seems unlikely to break any
254 code. Famous last words. (Dave Rolsky)
257 - Fixed the spelling of "compatibility", but we still have a
258 "check_metaclass_compatability" method for backwards
261 0.65 Mon September 1, 2008
262 For those not following the series of dev releases, the changes
263 from 0.64 from 0.65 can mostly be summed up as a lot performance
264 improvements by nothingmuch, including new optional XS versions of
265 some methods. Also, Class::MOP now works _without_ any XS modules,
266 for sad systems without a compiler.
269 - Added name and package_name XS accessors, and make sure all
270 the XS and Perl versions work the same way. (Dave Rolsky)
273 - The XS versions of various methods just returned undef when
274 called class methods, rather than dying like the pure Perl
275 versions. (Dave Rolsky)
277 0.64_07 Fri August 29, 2008
279 - Silenced warnings that managed to break Moose tests when XS
280 was loaded. (Dave Rolsky)
281 - Some XS versions of methods were ignored because of typos in
282 MOP.xs. (Dave Rolsky)
284 0.64_06 Mon August 25, 2008
285 * Class::MOP (MOP.xs)
286 - Another MS VC++ fix, cannot declare a variable in the middle
287 of a scope (Taro Nishino).
289 0.64_05 Sun August 24, 2008
291 - None of the dev releases actually loaded the XS properly, but
292 we silently fell back to the pure Perl version of the
295 * Class::MOP (MOP.xs)
296 - Replaced some code that used functions not available on Visual
297 C++ with some Perl XS API bits (Dave Rolsky).
299 0.64_04 Sat August 23, 2008
301 - Workaround a bug in 5.8.1's goto sub (nothingmuch)
303 * pod.t and pod_coveraget.t
304 - These are no longer shipped with the tarball because of bogus
305 failures from CPAN testers. (Dave Rolsky)
307 0.64_03 Thu August 21, 2008
308 * Class::MOP::Package
309 - Some (legit) code was misparsed by earlier 5.8.x
310 releases. (nothingmuch)
313 - Fix a constant in void context warning (nothingmuch)
315 0.64_02 Thu August 21, 2008
316 * Makefile.PL and Class::MOP
317 - Explicitly require Perl 5.8.0+ (Dave Rolsky)
320 - Add missing prereqs that got lost in the switch away from
323 * Class::MOP::Instance
324 - New method - get_all_attributes (nothingmuch)
326 0.64_01 Wed August 20, 2008
328 - We now check to see if you have a compiler. If you don't, the
329 module installs without some XS bits, but will work the same
330 as with XS. This should make it easier to install on platforms
331 without a compiler (like Windows). (Dave Rolsky)
334 - Perl 6 style attribute naming replaced with sane style ('methods', not
335 '%!methods'). These changes should not impact any existing API uses.
339 - Quite a number of optimizations based on profiling, including
340 allowing constructors to take hash references instead of
341 hashes, duplicating some frequently used code in XS, and
342 making constructors immutable. These changes should not impact
343 any existing API uses. (nothingmuch)
346 - Constructors now respect the meta attributes of their subclasses,
347 facilitating MOP extensibility. More related changes will happen in the
348 next several releases. (nothingmuch)
351 - New method - get_all_methods, replaces the deprecated
352 compute_all_applicable_methods. get_all_attributes provided for
353 consistency (nothingmuch)
354 - New method - wrap_method was refactored out of get_method_map
356 - New API for meta instance invalidation - invalidate_meta_instance,
357 invalidate_meta_instances, add_dependent_meta_instance,
358 remove_dependent_meta_instance, called automatically when attribute
359 definitions change and allows notification of dependent subclasses.
362 0.64 Sun August 3, 2008
363 * Class::MOP::Immutable
364 - fixing subtle edge case in immutable when you
366 - clean up option processing (nothingmuch)
368 * Class::MOP::Instance
369 - inlined initialize slot didn't match
370 non-inlined (nothingmuch)
372 0.63 Mon July 7, 2008
374 - load_class will initialize a metaclass even if
375 the class is already loaded (sartak)
376 - load_class now returns the metaclass instance
377 instead of just 1 (sartak)
380 - better error messages (sartak and Dave Rolsky)
382 0.62 Wed June 18, 2008
383 - in is_class_loaded, recognize scalar references (as opposed to globs) in
384 the symbol table as methods (these are optimized constant subs)
386 0.61 Fri. June 13, 2008
387 - Okay, lets give this another try and see if PAUSE
388 recognizes it correct this time.
390 0.60 Thurs. Jun 12, 2008
391 - Fixed a version number issue by bumping all modules
394 0.59 Thurs. Jun 12, 2008
395 !! Several fixes resulting in yet another 25-30% speedup !!
398 - now stores the instance of the instance
399 metaclass to avoid needless recomputation
400 and deletes it when the cache is blown
401 - introduce methods to query Class::MOP::Class for
402 the options used to make it immutable as well as
403 the proper immutable transformer. (groditi)
405 * Class::MOP::Package
406 - {add, has, get, remove}_package_symbol all
407 now accept a HASH ref argument as well as the
408 string. All internal usages now use the HASH
412 - MOP.xs does sanity checks on the coderef
414 - is_class_loaded check now uses code that
415 was improved in Moose's ClassName type
417 - nonsensical (undef, empty, reference) class
418 names now throw a more direct error in
420 - tests for this and other aspects of
426 Class::MOP::Method::Wrapped
427 Class::MOP::Attribute
428 - switched usage of reftype to ref because
431 0.58 Thurs. May 29, 2008
432 (late night release engineering)--
434 - fixing the version is META.yml, no functional
435 changes in this release
437 0.57 Wed. May 28, 2008
438 !! Several speedups resulting in 20-25% speedups !!
439 || (thanks to konobi, groditi, mst & CataMoose) !!
442 - made get_method_map use list_all_package_symbols
443 instead of manually grabbing each symbol
444 - streamlining &initialize somewhat, since it gets
447 * Class::MOP::Package
448 - made {get, has}_package_symbol not call
450 - inlining a few calls to &name with
451 direct HASH access key access
452 - added get_all_package_symbols to fetch
453 a HASH of items based on a type filter
454 similar to list_all_package_symbols
455 - added tests for this
458 Class::MOP::Method::Constructor
459 Class::MOP::Method::Generated
460 Class::MOP::Method::Accessor
461 - added more descriptive error message to help
462 keep people from wasting time tracking an error
463 that is easily fixed by upgrading.
465 * Class::MOP::Immutable
466 - Don't inline a destructor unless the user actually
468 - added tests for this
470 0.56 Saturday, May 24, 2008
472 - we now get the &check_package_cache_flag
473 function from MRO::Compat
474 - All XS based functionality now has a
475 Pure Perl alternative
476 - the CLASS_MOP_NO_XS environment variable
477 can now be used to force non-XS versions
480 * Class::MOP::Attribute
481 - add has_read_method and has_write_method
482 - get_{read,write}_method_ref now wraps the
483 anon-sub ref in the method metaclass when
485 - added tests for this
487 * Class::MOP::Immutable
488 - added the ability to "wrap" methods when
489 making the class immutable
492 - now handling the edge case of ->meta->identifier
493 dying by wrapping add_package_symbol to specifically
494 allow for it to work.
495 - added tests for this
497 * Class::MOP::Attribute
499 Class::MOP::Immutable
500 - any time a method meta object is constructed
501 we make sure to pass the correct package and
502 method name information
505 Class::MOP::Method::Wrapped
506 Class::MOP::Method::Generated
507 Class::MOP::Method::Accessor
508 Class::MOP::Method::Consructor
509 - the &wrap constructor method now requires that a
510 'package_name' and 'name' attribute are passed. This
511 is to help support the no-XS version, and will
512 throw an error if these are not supplied.
513 - all these classes are now bootstrapped properly
514 and now store the package_name and name attributes
517 ~ Build.PL has been removed since the
518 Module::Install support has been removed
520 0.55 Mon. April 28, 2008
521 - All classes now have proper C3 MRO support
522 - added MRO::Compat as a dependency to allow
523 for the C3 MRO support to Just Work in all
527 - rebless_instance now returns the instance
528 it has just blessed, this is mostly to
530 - set the attr correctly in rebless_instance
531 when it has no init_arg
532 - tweaked &linear_isa and &class_precedence_list
533 to support c3 classes.
535 0.54 Fri. March, 14, 2008

539 passed a value from @_ or $_ to squash
540 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
543 - make_{immutable,mutable} now return 1
545 - improved error handling in ->create method
546 - rebless_instance now takes extra params which
547 will be used to populate values
548 - added tests for this
551 - localizing the Data::Dumper configurations so
552 that it does not pollute others (RT #33509)
558 Class::MOP::Attribute
559 - these classes no longer define their own ->meta,
560 but instead just inherit from Class::MOP::Object
562 * Class::MOP::Instance
563 Class::MOP::Immutable
564 - these classes now inherit from Class::MOP::Object
567 - fixed the filename length on several
568 test files so we install on VMS better
570 - fixed incorrect use of catdir when it
571 should be catfile (RT #32385)
573 0.53 Thurs. Feb. 14, 1008
574 ~~ several doc. fixes and updates ~~
577 Class::MOP::Method::Constructor
578 Class::MOP::Attribute
579 - making init_arg accept an undefined value
580 to indicate that no constructor args can
581 be passed (thanks to nothingmuch)
582 - added tests for this
583 - added attribute initializer attribute (rjbs)
586 - making this use the new init_arg => undef
587 feature instead of the silly hack from
588 before (thanks to nothingmuch)
590 0.52 Tues. Jan. 22, 2008
592 - fixed bug in rebless_instance
595 * Class::MOP::Method::Constructor
596 - removed assumptions about the existence of
599 0.51 Mon. Jan. 14, 2008
600 ~~~ some misc. doc. fixes ~~~
601 ~~ updated copyright dates ~~
604 - now sets the IS_RUNNING_ON_5_10
605 constant so that we can take advantage
606 of some of the nice bits of 5.10
609 - uses the IS_RUNNING_ON_5_10 flag to
610 optimize the &linearized_isa method
611 and avoid the hack/check for circular
612 inheritence in &class_precedence_list
613 - added rebless_instance method (Sartak)
614 - added tests for this
616 * Class::MOP::Immutable
617 - the immutable class now keeps track of
618 the transformer which immutablized it
620 * Class::MOP::Instance
621 - added rebless_instance_structure method (Sartak)
622 - added tests for this
624 0.50 Fri. Dec. 21, 2007
626 - fixed bug in immutable to make sure that
627 transformation arguments are saved
629 - added tests for this
631 * Class::MOP::Immutable
632 - fixed a bug (see above)
634 * Class::MOP::Attribute
637 0.49 Fri. Dec. 14, 2007
638 !! Class::MOP now loads 2 x faster !!
639 !! with XS speedups (thanks konobi) !!
642 - removed the dependency on B
643 - added two XS functions (thanks konobi)
644 - get_code_info($code) which replaces all
645 the B fiddling we were doing with
646 faster/leaner XS level fiddling
647 - check_package_cache_flag($pkg_name) which
648 returns the PL_sub_generation variable to
649 be used to help manage method caching.
652 In 5.10 or greater this will actually
653 use the mro::get_pkg_gen instead to give
654 even more accurate caching information.
655 blblack++ for that stuff :)
658 - added the &subclasses method (thanks rlb)
659 - added the update_package_cache_flag and
660 reset_package_cache_flag which help keep
661 track of when we need to re-fetch the
663 - Several small improvements to take advantage
664 of the new method map caching features
666 0.48 Mon. Nov. 26, 2007
667 * Class::MOP::Attribute
668 - fixed get_read/write_method to handle the
669 HASH ref case, which makes the
670 get_read/write_method_ref handle it too.
671 - added more tests for this
673 0.47 Sat. Nov. 24, 2007
674 * Class::MOP::Attribute
675 - fixed misspelling in get_write_method_ref
676 - added more tests for this
678 0.46 Fri. Nov. 23, 2007
680 - added the linearized_isa method instead of constantly
681 pruning duplicate classes (this will be even more
682 useful in the 5.10-compat version coming soon)
684 * Class::MOP::Attribute
685 - added the get_read_method_ref and get_write_method_ref
686 methods which allow you to retrieve a CODE ref which
687 can always be used to read or write an attribute.
689 0.45 Thurs. Nov. 13, 2007
690 * Class::MOP::Attribute
691 - Fix error message on confess (groditi)
693 0.44 Thurs. Nov. 13, 2007
694 - Apparently I didn't make dist correctly (groditi)
696 0.43 Thurs. Nov. 13, 2007
698 - Add support for the 'builder' attribute (groditi)
701 - optimise metaclass-already-exists check in
702 construct_class_instance (groditi)
703 - duplicate check into initialize to save a
704 call through (groditi)
706 * Class::MOP::Attribute
707 - Add support for the 'builder' attribute (groditi)
708 - Make predicates check for the existence of a value, not whether
709 it is defined (groditi)
711 * Class::MOP::Instance
712 - Make predicates check for the existence of a value, not whether
713 it is defined (groditi)
715 * Class::MOP::Method::Accessor
716 - made this a subclass of Class::MOP::Method::Generated
717 - removed the relevant attributes
719 * Class::MOP::Method::Constructor
720 - fixed the cached values we had to be more sane
721 - made this a subclass of Class::MOP::Method::Generated
722 - fixed generated constructor so it properly handles
724 - added tests for this
725 - added the option to allow for both inlined and
726 non-inlined constructors.
727 - Update inlined methods for builder and predicate changes (groditi)
729 * Class::MOP::Method::Generated
730 - added this class as an abstract base for the
731 Class::MOP::Method::{Constructor,Accessor} classes
732 - added tests for this
735 - Alter tests (005, 014 020, 021) for new builder addition (groditi)
736 - Tests for new predicate behavior (and corrections to old tests) (groditi)
739 - Update ArrayRef based class example to work with predicate changes
741 0.42 Mon. July 16, 2007
742 !!! Horray for mst, he fixed it !!!
744 * Class::MOP::Package
745 - alter symbol table handling to deal with 5.8.x and 5.9.x
748 - Get rid of the crappy workaround from 0.40/41
750 0.41 Sun. July 15, 2007
752 Arghh!!! My TODO test didn't work, so I handle
753 it manually now so that people can use this
754 with 5.9.5/bleadperl without issue.
756 0.40 Tues, July 3, 2007
758 ~ marked a test in 003_methods.t as TODO
759 for perl 5.9.5 (this test is irrelvant to
760 the module functioning on 5.9.5 for the most
763 0.39 Mon. June 18, 2007
764 * Class::MOP::Immutable
765 - added make_metaclass_mutable + docs (groditi)
766 - removed unused variable
767 - added create_immutable_transformer
768 necessary for sane overloading of immutable behavior
769 - tests for this (groditi)
772 - Immutability can now be undone,
773 added make_mutable + tests + docs (groditi)
774 - Massive changes to the way Immutable is done
775 for details see comments next to make_immutable
776 This fixes a bug where custom metaclasses broke
777 when made immutable. We are now keeping one immutable
778 metaclass instance per metaclass instead of just one
779 to prevent isa hierarchy corruption. Memory use will go
780 up, but I suspect it will be neglible.
781 - New tests added for this behavior. (groditi)
783 0.38 Thurs. May 31, 2007
784 ~~ More documentation updates ~~
786 * Class::MOP::Package
787 - we now deal with stub methods properly
788 - added tests for this
789 - fixed some tests failing on 5.9.5 (thanks blblack)
791 * Class::MOP::Attribute
792 - added get_read_method and get_write_method
793 thanks to groditi for this code, tests
795 - added tests and POD for this
798 - fixed RT issue #27329, clone object now
799 handles undef values correctly.
800 - added tests for this
801 - Corrected anon-class handling so that they
802 will not get reaped when instances still
803 exist which need to reference them. This is
804 the correct behavior, hopefully this is an
805 obscure enough feature that there are not too
806 many work arounds out in the wild.
807 - added tests for this by groditi
808 - updated docs to explain this
811 - load custom metaclasses automatically (thanks groditi)
812 - added tests for this behavior

815 ~~ Many, many documentation updates ~~
818 - added &load_class and &is_class_loaded
819 - added tests and docs for these
821 * Class::MOP::Attribute
822 - default now checks the instance with defined to
823 avoid setting off bool-overloads (found by Carl Franks)
827 - bad name in a test, causing meaningless failuress.
833 - All attribute names are now consistent and follow Perl 6
834 style (prefixed with the sigil, and ! as the twigil for
835 private attrs). This should not affect any code, unless
836 you broke encapsulation, in which case, it is your problem
839 !! Class::MOP::Class::Immutable has been removed
841 * Class::MOP::Method::Constructor
842 - this has been moved out of Class::MOP::Class::Immutable
843 and is a proper subclass of Class::MOP::Method now.
846 - this module now uses Class::MOP::Immutable for the
847 immutable transformation instead of
848 Class::MOP::Class::Immutable.
850 + Class::MOP::Immutable
851 - this module now controls the transformation from a mutable
852 to an immutable version of the class. Docs for this will
853 be coming eventually.
856 0.36 Sun. Nov. 5, 2006
858 - added a few 'no warnings' lines to keep annoying
859 (and meaningless) warnings from chirping during
863 - some more bootstrapping is now done on the new
866 * Class::MOP::Class::Immutable
868 - constructor generation is now handled by
869 the Class::MOP::Method::Constructor class
871 * Class::MOP::Method::Constructor
872 - created this to handle constructor generation
873 in Class::MOP::Class::Immutable
875 * Class::MOP::Attribute
877 - attributes now delegate to the
878 Class::MOP::Method::Accessor to generate
881 * Class::MOP::Method::Accessor
882 - all accessor generation functions from
883 Class::MOP::Attribute have been moved here
885 0.35 Sat. Sept. 30, 2006

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

906 but are actual objects which can be CODE-ified
907 - adjusted tests to compensate
908 - adjusted docs for this
911 - changed how methods are dealt with to
912 encapsulate most of the work into the
913 &get_method_map method
914 - made several adjustments for the change
915 in Class::MOP::Method
916 - &add_attribute now checks if you are adding
917 a duplicate name, and properly removes the
918 old one before installing the new one
919 - added tests for this
920 - adjusted docs for this
922 * Class::MOP::Class::Immutable
923 - added caching of &get_method_map

928 - added filtering capabilities to
929 &list_all_package_symbols
931 0.34 Sat. Aug. 26, 2006
933 - added the %:methods attribute, which like
934 the $:version and such just actually goes
935 to the symbol table to get it's stuff.
936 However, it makes the MOP more complete.
938 - The &create method now requires that all
939 but the package name now is passed in as
940 named parameters. See docs for more info.
941 - updated docs and tests for this
944 - added &dump method to easily Data::Dumper
948 - cleaned up the initialization of attributes
949 which do not store things in the instance

958 and it is now in Class::MOP itself.
961 - moved all the metaclass cache stuff here

965 - reference values (other than CODE refs)
966 are no longer allowed for defaults
967 - added tests for this
969 * Class::MOP::Package
970 - fixed an issue with perl 5.8.1 and how it deals
971 with symbol tables. The namespace hash is now
972 always reloaded from the symbol table.
974 ~ lots of misc. documentation cleanup
976 0.32 Sat. Aug. 12, 2006
977 + added Class::MOP::Object so that the
978 metamodel is more complete (and closer
979 to what Perl 6 will probably be).
981 * Class::MOP::Package
982 - refactored entire class, this is now
983 the primary gateway between the metaclass
984 and the Perl 5 symbol table
985 - added many tests for this
986 - this class is now a subclass of
988 - added some tests to reflect this
991 - refactored all symbol table access to
992 use Class::MOP::Package methods instead
995 - adding the $:version attribute in the bootstrap
996 so that Module has a version as an attribute

1018 anywhere within the class hierarchy
1020 * Class::MOP::Attribute
1021 - added &set_value and &get_value for getting
1022 the value of the attribute for a particular
1025 0.30 Wed. July 5, 2006
1026 ---------------------------------------
1027 This is the first version of Class::MOP
1028 to introduce the immutable features which
1029 will be used for optimizating the MOP.
1030 This support should still be considered
1031 experimental, but moving towards stability.
1032 ---------------------------------------
1034 * Created Class::MOP::Class::Immutable
1036 * Created the Class::MOP::Package and
1037 Class::MOP::Module classes to more
1038 closely conform to Perl 6's meta-model
1041 - now inherits from Class::MOP::Module
1042 - several methods moved to ::Module and
1043 ::Package and now inherited
1044 - added tests for this
1046 * Class::MOP::Instance
1047 - added an is_inlinable method to allow other
1048 classes to check before they attempt to optimize.
1049 - added an inline_create_instance to inline
1050 instance creation (of course)
1053 - the Class::MOP::Class::*_package_variable
1054 methods are all now methods of Class::MOP::Package
1055 and called *_package_symbol instead. This is
1056 because they are now more general purpose symbol
1057 table manipulation methods.
1059 0.29_02 Thurs. June 22, 2006
1060 ++ DEVELOPER RELEASE ++

1118 - attribute slot initialization is now the responsibility
1119 of the attribute itself, and construct_instance now
1120 delegates appropriately
1122 * Class::MOP::Attribute
1123 - attribute slot initialization is now the responsibility
1124 of the attribute itself, so we added a method for it
1125 called initialize_instance_slot

1202 - changed how clone_instance behaves, it now only does a
1203 shallow clone (see docs for more details)
1204 - added docs and tests
1206 0.10 Tues Feb. 14, 2006
1207 ** This release was mostly about writing more tests and
1208 cleaning out old and dusty code, the MOP should now
1209 be considered "ready to use".
1211 - adding more tests to get coverage up a little higher,
1212 mostly testing errors and edge cases.
1213 - test coverage is now at 99%

1231 0.06 Thurs Feb. 9, 2006
1233 - adding new metaclass pragma to make setting up the
1234 metaclass a little more straightforward
1237 - clean up bootstrapping to include more complete
1238 attribute definitions for Class::MOP::Class and
1239 Class::MOP::Attribute (accessors, readers, writers,
1240 etc.) ... it is redundant, but is useful meta-info
1244 - fixing minor meta-circularity issue with &meta, it
1245 is now more useful for subclasses
1246 - added &get_attribute_map as an accessor for the
1247 hash of attribute meta objects
1248 - &compute_all_applicable_attributes now just returns
1249 the attribute meta-object, rather than the HASH ref
1250 since all the same info can be gotten from the
1251 attribute meta-object itself
1252 - updated docs & tests to reflect

1282 - adjusted the example code and tests to use the new
1283 &attribute_metaclass feature of Class::MOP::Class

1314 - moving examples from t/lib/* to examples/*
1315 - adding POD documentation to the examples
