1 Revision history for Perl extension Class-MOP.
5 - We now check to see if you have a compiler. If you don't, the
6 module installs without some XS bits, but will work the same
7 as with XS. This should make it easier to install on platforms
8 without a compiler (like Windows). (Dave Rolsky)
11 - Quite a number of optimizations based on profiling, including
12 allowing constructors to take hash references instead of
13 hashes, duplicating some frequently used code in XS, and
14 making constructors immutable. These changes should not impact
15 any existing API uses. (nothingmuch)
18 - New method - get_all_methods (nothingmuch)
19 - New method - wrap_method was refactored out of get_method_map
21 - New method - invalidate_meta_instance (nothingmuch)
23 0.64 Sun August 3, 2008
24 * Class::MOP::Immutable
25 - fixing subtle edge case in immutable when you
27 - clean up option processing (nothingmuch)
29 * Class::MOP::Instance
30 - inlined initialize slot didn't match
31 non-inlined (nothingmuch)
35 - load_class will initialize a metaclass even if
36 the class is already loaded (sartak)
37 - load_class now returns the metaclass instance
38 instead of just 1 (sartak)
41 - better error messages (sartak and Dave Rolsky)
43 0.62 Wed June 18, 2008
44 - in is_class_loaded, recognize scalar references (as opposed to globs) in
45 the symbol table as methods (these are optimized constant subs)
47 0.61 Fri. June 13, 2008
48 - Okay, lets give this another try and see if PAUSE
49 recognizes it correct this time.
51 0.60 Thurs. Jun 12, 2008
52 - Fixed a version number issue by bumping all modules
55 0.59 Thurs. Jun 12, 2008
56 !! Several fixes resulting in yet another 25-30% speedup !!
59 - now stores the instance of the instance
60 metaclass to avoid needless recomputation
61 and deletes it when the cache is blown
62 - introduce methods to query Class::MOP::Class for
63 the options used to make it immutable as well as
64 the proper immutable transformer. (groditi)
67 - {add, has, get, remove}_package_symbol all
68 now accept a HASH ref argument as well as the
69 string. All internal usages now use the HASH
73 - MOP.xs does sanity checks on the coderef
75 - is_class_loaded check now uses code that
76 was improved in Moose's ClassName type
78 - nonsensical (undef, empty, reference) class
79 names now throw a more direct error in
81 - tests for this and other aspects of
87 Class::MOP::Method::Wrapped
89 - switched usage of reftype to ref because
92 0.58 Thurs. May 29, 2008
93 (late night release engineering)--
95 - fixing the version is META.yml, no functional
96 changes in this release
98 0.57 Wed. May 28, 2008
99 !! Several speedups resulting in 20-25% speedups !!
100 || (thanks to konobi, groditi, mst & CataMoose) !!
103 - made get_method_map use list_all_package_symbols
104 instead of manually grabbing each symbol
105 - streamlining &initialize somewhat, since it gets
108 * Class::MOP::Package
109 - made {get, has}_package_symbol not call
111 - inlining a few calls to &name with
112 direct HASH access key access
113 - added get_all_package_symbols to fetch
114 a HASH of items based on a type filter
115 similar to list_all_package_symbols
116 - added tests for this
119 Class::MOP::Method::Constructor
120 Class::MOP::Method::Generated
121 Class::MOP::Method::Accessor
122 - added more descriptive error message to help
123 keep people from wasting time tracking an error
124 that is easily fixed by upgrading.
126 * Class::MOP::Immutable
127 - Don't inline a destructor unless the user actually
129 - added tests for this
131 0.56 Saturday, May 24, 2008
133 - we now get the &check_package_cache_flag
134 function from MRO::Compat
135 - All XS based functionality now has a
136 Pure Perl alternative
137 - the CLASS_MOP_NO_XS environment variable
138 can now be used to force non-XS versions
141 * Class::MOP::Attribute
142 - add has_read_method and has_write_method
143 - get_{read,write}_method_ref now wraps the
144 anon-sub ref in the method metaclass when
146 - added tests for this
148 * Class::MOP::Immutable
149 - added the ability to "wrap" methods when
150 making the class immutable
153 - now handling the edge case of ->meta->identifier
154 dying by wrapping add_package_symbol to specifically
155 allow for it to work.
156 - added tests for this
158 * Class::MOP::Attribute
160 Class::MOP::Immutable
161 - any time a method meta object is constructed
162 we make sure to pass the correct package and
163 method name information
166 Class::MOP::Method::Wrapped
167 Class::MOP::Method::Generated
168 Class::MOP::Method::Accessor
169 Class::MOP::Method::Consructor
170 - the &wrap constructor method now requires that a
171 'package_name' and 'name' attribute are passed. This
172 is to help support the no-XS version, and will
173 throw an error if these are not supplied.
174 - all these classes are now bootstrapped properly
175 and now store the package_name and name attributes
178 ~ Build.PL has been removed since the
179 Module::Install support has been removed
181 0.55 Mon. April 28, 2008
182 - All classes now have proper C3 MRO support
183 - added MRO::Compat as a dependency to allow
184 for the C3 MRO support to Just Work in all
188 - rebless_instance now returns the instance
189 it has just blessed, this is mostly to
191 - set the attr correctly in rebless_instance
192 when it has no init_arg
193 - tweaked &linear_isa and &class_precedence_list
194 to support c3 classes.
196 0.54 Fri. March, 14, 2008
199 - making sure that load_class never gets
200 passed a value from @_ or $_ to squash
201 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
204 - make_{immutable,mutable} now return 1
206 - improved error handling in ->create method
207 - rebless_instance now takes extra params which
208 will be used to populate values
209 - added tests for this
212 - localizing the Data::Dumper configurations so
213 that it does not pollute others (RT #33509)
219 Class::MOP::Attribute
220 - these classes no longer define their own ->meta,
221 but instead just inherit from Class::MOP::Object
223 * Class::MOP::Instance
224 Class::MOP::Immutable
225 - these classes now inherit from Class::MOP::Object
228 - fixed the filename length on several
229 test files so we install on VMS better
231 - fixed incorrect use of catdir when it
232 should be catfile (RT #32385)

235 ~~ several doc. fixes and updates ~~
238 Class::MOP::Method::Constructor

241 to indicate that no constructor args can
242 be passed (thanks to nothingmuch)
243 - added tests for this
244 - added attribute initializer attribute (rjbs)
247 - making this use the new init_arg => undef
248 feature instead of the silly hack from
249 before (thanks to nothingmuch)
251 0.52 Tues. Jan. 22, 2008
253 - fixed bug in rebless_instance
256 * Class::MOP::Method::Constructor
257 - removed assumptions about the existence of
260 0.51 Mon. Jan. 14, 2008
261 ~~~ some misc. doc. fixes ~~~
262 ~~ updated copyright dates ~~
265 - now sets the IS_RUNNING_ON_5_10
266 constant so that we can take advantage
267 of some of the nice bits of 5.10
270 - uses the IS_RUNNING_ON_5_10 flag to
271 optimize the &linearized_isa method
272 and avoid the hack/check for circular
273 inheritence in &class_precedence_list
274 - added rebless_instance method (Sartak)
275 - added tests for this
277 * Class::MOP::Immutable
278 - the immutable class now keeps track of

288 transformation arguments are saved
290 - added tests for this
292 * Class::MOP::Immutable
293 - fixed a bug (see above)

299 !! Class::MOP now loads 2 x faster !!
300 !! with XS speedups (thanks konobi) !!
303 - removed the dependency on B
304 - added two XS functions (thanks konobi)
305 - get_code_info($code) which replaces all
306 the B fiddling we were doing with
307 faster/leaner XS level fiddling
308 - check_package_cache_flag($pkg_name) which
309 returns the PL_sub_generation variable to
310 be used to help manage method caching.
313 In 5.10 or greater this will actually
314 use the mro::get_pkg_gen instead to give
315 even more accurate caching information.
316 blblack++ for that stuff :)
319 - added the &subclasses method (thanks rlb)
320 - added the update_package_cache_flag and
321 reset_package_cache_flag which help keep
322 track of when we need to re-fetch the
324 - Several small improvements to take advantage
325 of the new method map caching features
327 0.48 Mon. Nov. 26, 2007
328 * Class::MOP::Attribute

337 - added more tests for this
339 0.46 Fri. Nov. 23, 2007
341 - added the linearized_isa method instead of constantly
342 pruning duplicate classes (this will be even more
343 useful in the 5.10-compat version coming soon)
345 * Class::MOP::Attribute
346 - added the get_read_method_ref and get_write_method_ref
347 methods which allow you to retrieve a CODE ref which
348 can always be used to read or write an attribute.
350 0.45 Thurs. Nov. 13, 2007
351 * Class::MOP::Attribute
352 - Fix error message on confess (groditi)
354 0.44 Thurs. Nov. 13, 2007

359 - Add support for the 'builder' attribute (groditi)
362 - optimise metaclass-already-exists check in
363 construct_class_instance (groditi)
364 - duplicate check into initialize to save a
365 call through (groditi)
367 * Class::MOP::Attribute
368 - Add support for the 'builder' attribute (groditi)
369 - Make predicates check for the existence of a value, not whether
370 it is defined (groditi)

378 - removed the relevant attributes
380 * Class::MOP::Method::Constructor
381 - fixed the cached values we had to be more sane
382 - made this a subclass of Class::MOP::Method::Generated
383 - fixed generated constructor so it properly handles
385 - added tests for this
386 - added the option to allow for both inlined and
387 non-inlined constructors.
388 - Update inlined methods for builder and predicate changes (groditi)
390 * Class::MOP::Method::Generated
391 - added this class as an abstract base for the
392 Class::MOP::Method::{Constructor,Accessor} classes

405 * Class::MOP::Package
406 - alter symbol table handling to deal with 5.8.x and 5.9.x
409 - Get rid of the crappy workaround from 0.40/41
411 0.41 Sun. July 15, 2007
413 Arghh!!! My TODO test didn't work, so I handle
414 it manually now so that people can use this
415 with 5.9.5/bleadperl without issue.
417 0.40 Tues, July 3, 2007
419 ~ marked a test in 003_methods.t as TODO
420 for perl 5.9.5 (this test is irrelvant to
421 the module functioning on 5.9.5 for the most
424 0.39 Mon. June 18, 2007
425 * Class::MOP::Immutable
426 - added make_metaclass_mutable + docs (groditi)
427 - removed unused variable
428 - added create_immutable_transformer
429 necessary for sane overloading of immutable behavior
430 - tests for this (groditi)
433 - Immutability can now be undone,
434 added make_mutable + tests + docs (groditi)
435 - Massive changes to the way Immutable is done
436 for details see comments next to make_immutable
437 This fixes a bug where custom metaclasses broke
438 when made immutable. We are now keeping one immutable
439 metaclass instance per metaclass instead of just one
440 to prevent isa hierarchy corruption. Memory use will go
441 up, but I suspect it will be neglible.
442 - New tests added for this behavior. (groditi)
444 0.38 Thurs. May 31, 2007
445 ~~ More documentation updates ~~
447 * Class::MOP::Package
448 - we now deal with stub methods properly
449 - added tests for this
450 - fixed some tests failing on 5.9.5 (thanks blblack)
452 * Class::MOP::Attribute
453 - added get_read_method and get_write_method
454 thanks to groditi for this code, tests
456 - added tests and POD for this
459 - fixed RT issue #27329, clone object now
460 handles undef values correctly.
461 - added tests for this
462 - Corrected anon-class handling so that they
463 will not get reaped when instances still
464 exist which need to reference them. This is
465 the correct behavior, hopefully this is an
466 obscure enough feature that there are not too
467 many work arounds out in the wild.
468 - added tests for this by groditi
469 - updated docs to explain this
472 - load custom metaclasses automatically (thanks groditi)
473 - added tests for this behavior
475 0.37 Sat. March 10, 2007
476 ~~ Many, many documentation updates ~~
479 - added &load_class and &is_class_loaded
480 - added tests and docs for these
482 * Class::MOP::Attribute
483 - default now checks the instance with defined to
484 avoid setting off bool-overloads (found by Carl Franks)
488 - bad name in a test, causing meaningless failuress.
494 - All attribute names are now consistent and follow Perl 6
495 style (prefixed with the sigil, and ! as the twigil for
496 private attrs). This should not affect any code, unless
497 you broke encapsulation, in which case, it is your problem
500 !! Class::MOP::Class::Immutable has been removed
502 * Class::MOP::Method::Constructor
503 - this has been moved out of Class::MOP::Class::Immutable
504 and is a proper subclass of Class::MOP::Method now.
507 - this module now uses Class::MOP::Immutable for the
508 immutable transformation instead of
509 Class::MOP::Class::Immutable.
511 + Class::MOP::Immutable
512 - this module now controls the transformation from a mutable
513 to an immutable version of the class. Docs for this will
514 be coming eventually.
517 0.36 Sun. Nov. 5, 2006
519 - added a few 'no warnings' lines to keep annoying
520 (and meaningless) warnings from chirping during
524 - some more bootstrapping is now done on the new
527 * Class::MOP::Class::Immutable
529 - constructor generation is now handled by
530 the Class::MOP::Method::Constructor class
532 * Class::MOP::Method::Constructor
533 - created this to handle constructor generation
534 in Class::MOP::Class::Immutable
536 * Class::MOP::Attribute
538 - attributes now delegate to the
539 Class::MOP::Method::Accessor to generate
542 * Class::MOP::Method::Accessor
543 - all accessor generation functions from
544 Class::MOP::Attribute have been moved here
546 0.35 Sat. Sept. 30, 2006
548 * scripts/class_browser.pl
549 - initial prototype of a class browser, more
550 on this to come. Comments and patches are
554 - All Class::MOP::* accessors are no longer
555 re-generated in the bootstrap, instead
556 they are aliased from the originals
557 - fixed tests to reflect
558 - added Class::MOP::Method (and its subclasses)
560 - adjusted tests for this
561 - added the Class::MOP::Instance attributes
566 - methods are no longer blessed CODE refs
567 but are actual objects which can be CODE-ified
568 - adjusted tests to compensate
569 - adjusted docs for this
572 - changed how methods are dealt with to
573 encapsulate most of the work into the
574 &get_method_map method
575 - made several adjustments for the change
576 in Class::MOP::Method
577 - &add_attribute now checks if you are adding
578 a duplicate name, and properly removes the
579 old one before installing the new one
580 - added tests for this
581 - adjusted docs for this
583 * Class::MOP::Class::Immutable
584 - added caching of &get_method_map
585 - fixed issue with &get_package_symbol
586 - cleaned up the methods that die (patch by David Wheeler)
588 * Class::MOP::Package
589 - added filtering capabilities to
590 &list_all_package_symbols
592 0.34 Sat. Aug. 26, 2006
594 - added the %:methods attribute, which like
595 the $:version and such just actually goes
596 to the symbol table to get it's stuff.
597 However, it makes the MOP more complete.
599 - The &create method now requires that all
600 but the package name now is passed in as
601 named parameters. See docs for more info.
602 - updated docs and tests for this
605 - added &dump method to easily Data::Dumper
609 - cleaned up the initialization of attributes
610 which do not store things in the instance
611 - added the %:methods attribute definition to
614 ~ lots of misc. test cleanup
616 0.33 Sat. Aug. 19, 2006
618 - moved the metaclass cache out of here
619 and it is now in Class::MOP itself.
622 - moved all the metaclass cache stuff here
623 - fixed all tests for this
625 * Class::MOP::Attribute
626 - reference values (other than CODE refs)
627 are no longer allowed for defaults
628 - added tests for this
630 * Class::MOP::Package
631 - fixed an issue with perl 5.8.1 and how it deals
632 with symbol tables. The namespace hash is now
633 always reloaded from the symbol table.
635 ~ lots of misc. documentation cleanup
637 0.32 Sat. Aug. 12, 2006
638 + added Class::MOP::Object so that the
639 metamodel is more complete (and closer
640 to what Perl 6 will probably be).
642 * Class::MOP::Package
643 - refactored entire class, this is now
644 the primary gateway between the metaclass
645 and the Perl 5 symbol table
646 - added many tests for this
647 - this class is now a subclass of
649 - added some tests to reflect this
652 - refactored all symbol table access to
653 use Class::MOP::Package methods instead
656 - adding the $:version attribute in the bootstrap
657 so that Module has a version as an attribute
658 - see comment in Class::MOP for details
659 - added the $:authority attribute to this module
660 as well as an &identifier method, to bring us
661 ever closer to Perl 6 goodness

679 anywhere within the class hierarchy
681 * Class::MOP::Attribute
682 - added &set_value and &get_value for getting
683 the value of the attribute for a particular
686 0.30 Wed. July 5, 2006
687 ---------------------------------------
688 This is the first version of Class::MOP
689 to introduce the immutable features which
690 will be used for optimizating the MOP.
691 This support should still be considered
692 experimental, but moving towards stability.
693 ---------------------------------------
695 * Created Class::MOP::Class::Immutable
697 * Created the Class::MOP::Package and
698 Class::MOP::Module classes to more
699 closely conform to Perl 6's meta-model
702 - now inherits from Class::MOP::Module
703 - several methods moved to ::Module and
704 ::Package and now inherited
705 - added tests for this
707 * Class::MOP::Instance
708 - added an is_inlinable method to allow other
709 classes to check before they attempt to optimize.
710 - added an inline_create_instance to inline
711 instance creation (of course)
714 - the Class::MOP::Class::*_package_variable
715 methods are all now methods of Class::MOP::Package
716 and called *_package_symbol instead. This is
717 because they are now more general purpose symbol
718 table manipulation methods.
720 0.29_02 Thurs. June 22, 2006
721 ++ DEVELOPER RELEASE ++
723 - small change in &create so that it behaves
724 properly when inherited

728 ++ DEVELOPER RELEASE ++
729 - This release works in combination with
730 Moose 0.09_01, it is a developer release

775 - added tests for this
776 - added get_all_metaclasses, get_all_metaclass_names
777 and get_all_metaclass_instances method to allow
778 access to all the cached metaclass objects.
779 - attribute slot initialization is now the responsibility
780 of the attribute itself, and construct_instance now
781 delegates appropriately
783 * Class::MOP::Attribute
784 - attribute slot initialization is now the responsibility
785 of the attribute itself, so we added a method for it
786 called initialize_instance_slot
789 - adjusted all the examples to use the new attribute
790 initialize_instance_slot method
792 0.24 Tues. April 11, 2006

807 - adjusted all /example files to comply
809 0.22 Mon. March 20, 2006
811 - localized $@ in the *_package_variable functions
812 because otherwise, it does ugly things in Moose.
813 - added test case for this
815 0.21 Wed. March 15, 2006
817 - fixed issue where metaclasses are reaped from
818 our cache in global destruction, and so are not
819 available in DESTORY calls
821 0.20 Thurs. March 2, 2006
822 - removed the dependency for Clone since
823 we no longer to deep-cloning by default.

827 &fully_qualified_name methods, some of
828 which were formerly private subs in

833 before, after and around modifiers
834 - added tests and docs for this feature
837 - improved &get_package_symbol
838 - &version and &superclasses now use it
839 - methods are now blessed into Class::MOP::Method
841 - added methods to install CLOS-style method modifiers
842 - &add_before_method_modifier
843 - &add_after_method_modifier
844 - &add_around_method_modifier
845 - added tests and docs for these
846 - added &find_next_method_by_name which finds the
847 equivalent of SUPER::method_name
849 0.12 Thurs. Feb 23, 2006
850 - reduced the dependency on B, no need to always
854 - added docs to the C3 method dispatch order test
855 - fixed missing Algorithm::C3 dependency by making

858 0.11 Mon Feb. 20, 2006
860 - added example of changing method dispatch order to C3
863 - changed how clone_instance behaves, it now only does a
864 shallow clone (see docs for more details)
865 - added docs and tests
867 0.10 Tues Feb. 14, 2006
868 ** This release was mostly about writing more tests and
869 cleaning out old and dusty code, the MOP should now
870 be considered "ready to use".
872 - adding more tests to get coverage up a little higher,
873 mostly testing errors and edge cases.
874 - test coverage is now at 99%
877 - no longer optionally exports to UNIVERSAL::meta or
878 creates a custom metaclass generator, use the
879 metaclass pragma instead.
882 - fixed a number of minor issues which came up in the
883 error/edge-case tests
885 * Class::MOP::Attribute
886 - fixed a number of minor issues which came up in the
887 error/edge-case tests
890 - fixing the AttributesWithHistory example, it was broken.
892 0.06 Thurs Feb. 9, 2006
894 - adding new metaclass pragma to make setting up the
895 metaclass a little more straightforward
898 - clean up bootstrapping to include more complete
899 attribute definitions for Class::MOP::Class and
900 Class::MOP::Attribute (accessors, readers, writers,
901 etc.) ... it is redundant, but is useful meta-info
905 - fixing minor meta-circularity issue with &meta, it
906 is now more useful for subclasses
907 - added &get_attribute_map as an accessor for the
908 hash of attribute meta objects
909 - &compute_all_applicable_attributes now just returns
910 the attribute meta-object, rather than the HASH ref
911 since all the same info can be gotten from the
912 attribute meta-object itself
913 - updated docs & tests to reflect
914 - added &clone_instance method which does a deep clone
915 of the instance structure created by &construct_instance
916 - added docs & tests for this
917 - added Clone as a dependency
918 - added &new_object and &clone_object convience methods to
919 return blessed new or cloned instances
920 - they handle Class::MOP::Class singletons correctly too
921 - added docs & tests for this
922 - cleaned up the &constuct_class_instance so that it behaves
923 more like &construct_instance (and managed the singletons too)
924 - added the &check_metaclass_compatibility method to make sure
925 that metaclasses are upward and downward compatible.
926 - added tests and docs for this
929 - adjusting code to use the &Class::MOP::Class::meta
931 - adjusting code to use the metaclass pragma
933 0.05 Sat Feb. 4, 2006
935 - added the &attribute_metaclass and &method_metaclass
936 attributes which contain a metaclass name to use for
937 attributes/methods respectively
940 - bootstrap additional attributes for Class::MOP::Class
943 - adjusted the example code and tests to use the new
944 &attribute_metaclass feature of Class::MOP::Class

950 - some documentation suggestions from #perl6
952 * Class::MOP::Attribute
