1 Revision history for Perl extension Class-MOP.
4 ~ added MRO::Compat as a dependency ~
5 ~ all classes now have proper c3 support ~
8 - rebless_instance now returns the instance
9 it has just blessed, this is mostly to
11 - set the attr correctly in rebless_instance
12 when it has no init_arg
13 - tweaked &linear_isa and &class_precedence_list
14 to support c3 classes.
16 0.54 Fri. March, 14, 2008
19 - making sure that load_class never gets
20 passed a value from @_ or $_ to squash
21 Ovid's bug (http://use.perl.org/~Ovid/journal/35763)
24 - make_{immutable,mutable} now return 1
26 - improved error handling in ->create method
27 - rebless_instance now takes extra params which
28 will be used to populate values
29 - added tests for this
32 - localizing the Data::Dumper configurations so
33 that it does not pollute others (RT #33509)
40 - these classes no longer define their own ->meta,
41 but instead just inherit from Class::MOP::Object
43 * Class::MOP::Instance
45 - these classes now inherit from Class::MOP::Object
48 - fixed the filename length on several
49 test files so we install on VMS better
51 - fixed incorrect use of catdir when it
52 should be catfile (RT #32385)
54 0.53 Thurs. Feb. 14, 1008
55 ~~ several doc. fixes and updates ~~
58 Class::MOP::Method::Constructor
60 - making init_arg accept an undefined value
61 to indicate that no constructor args can
62 be passed (thanks to nothingmuch)
63 - added tests for this
64 - added attribute initializer attribute (rjbs)
67 - making this use the new init_arg => undef
68 feature instead of the silly hack from
69 before (thanks to nothingmuch)
71 0.52 Tues. Jan. 22, 2008
73 - fixed bug in rebless_instance
76 * Class::MOP::Method::Constructor
77 - removed assumptions about the existence of
80 0.51 Mon. Jan. 14, 2008
81 ~~~ some misc. doc. fixes ~~~
82 ~~ updated copyright dates ~~
85 - now sets the IS_RUNNING_ON_5_10
86 constant so that we can take advantage
87 of some of the nice bits of 5.10
90 - uses the IS_RUNNING_ON_5_10 flag to
91 optimize the &linearized_isa method
92 and avoid the hack/check for circular
93 inheritence in &class_precedence_list
94 - added rebless_instance method (Sartak)
95 - added tests for this
97 * Class::MOP::Immutable
98 - the immutable class now keeps track of
99 the transformer which immutablized it
101 * Class::MOP::Instance
102 - added rebless_instance_structure method (Sartak)
103 - added tests for this
105 0.50 Fri. Dec. 21, 2007
107 - fixed bug in immutable to make sure that
108 transformation arguments are saved
110 - added tests for this
112 * Class::MOP::Immutable
113 - fixed a bug (see above)
115 * Class::MOP::Attribute
118 0.49 Fri. Dec. 14, 2007
119 !! Class::MOP now loads 2 x faster !!
120 !! with XS speedups (thanks konobi) !!
123 - removed the dependency on B
124 - added two XS functions (thanks konobi)
125 - get_code_info($code) which replaces all
126 the B fiddling we were doing with
127 faster/leaner XS level fiddling
128 - check_package_cache_flag($pkg_name) which
129 returns the PL_sub_generation variable to
130 be used to help manage method caching.
133 In 5.10 or greater this will actually
134 use the mro::get_pkg_gen instead to give
135 even more accurate caching information.
136 blblack++ for that stuff :)
139 - added the &subclasses method (thanks rlb)
140 - added the update_package_cache_flag and
141 reset_package_cache_flag which help keep
142 track of when we need to re-fetch the
144 - Several small improvements to take advantage
145 of the new method map caching features
147 0.48 Mon. Nov. 26, 2007
148 * Class::MOP::Attribute
149 - fixed get_read/write_method to handle the
150 HASH ref case, which makes the

152 - added more tests for this
154 0.47 Sat. Nov. 24, 2007
155 * Class::MOP::Attribute
156 - fixed misspelling in get_write_method_ref
157 - added more tests for this
159 0.46 Fri. Nov. 23, 2007
161 - added the linearized_isa method instead of constantly
162 pruning duplicate classes (this will be even more
163 useful in the 5.10-compat version coming soon)
165 * Class::MOP::Attribute
166 - added the get_read_method_ref and get_write_method_ref
167 methods which allow you to retrieve a CODE ref which
168 can always be used to read or write an attribute.
170 0.45 Thurs. Nov. 13, 2007
171 * Class::MOP::Attribute
172 - Fix error message on confess (groditi)
174 0.44 Thurs. Nov. 13, 2007

182 - optimise metaclass-already-exists check in
183 construct_class_instance (groditi)

200 * Class::MOP::Method::Constructor
201 - fixed the cached values we had to be more sane
202 - made this a subclass of Class::MOP::Method::Generated
203 - fixed generated constructor so it properly handles
205 - added tests for this
206 - added the option to allow for both inlined and
207 non-inlined constructors.
208 - Update inlined methods for builder and predicate changes (groditi)
210 * Class::MOP::Method::Generated
211 - added this class as an abstract base for the
212 Class::MOP::Method::{Constructor,Accessor} classes

226 - alter symbol table handling to deal with 5.8.x and 5.9.x
229 - Get rid of the crappy workaround from 0.40/41
231 0.41 Sun. July 15, 2007
233 Arghh!!! My TODO test didn't work, so I handle
234 it manually now so that people can use this
235 with 5.9.5/bleadperl without issue.
237 0.40 Tues, July 3, 2007
239 ~ marked a test in 003_methods.t as TODO
240 for perl 5.9.5 (this test is irrelvant to
241 the module functioning on 5.9.5 for the most
244 0.39 Mon. June 18, 2007
245 * Class::MOP::Immutable
246 - added make_metaclass_mutable + docs (groditi)
247 - removed unused variable
248 - added create_immutable_transformer
249 necessary for sane overloading of immutable behavior
250 - tests for this (groditi)
253 - Immutability can now be undone,
254 added make_mutable + tests + docs (groditi)
255 - Massive changes to the way Immutable is done
256 for details see comments next to make_immutable
257 This fixes a bug where custom metaclasses broke
258 when made immutable. We are now keeping one immutable
259 metaclass instance per metaclass instead of just one
260 to prevent isa hierarchy corruption. Memory use will go
261 up, but I suspect it will be neglible.
262 - New tests added for this behavior. (groditi)
264 0.38 Thurs. May 31, 2007
265 ~~ More documentation updates ~~
267 * Class::MOP::Package
268 - we now deal with stub methods properly
269 - added tests for this
270 - fixed some tests failing on 5.9.5 (thanks blblack)
272 * Class::MOP::Attribute
273 - added get_read_method and get_write_method
274 thanks to groditi for this code, tests
276 - added tests and POD for this
279 - fixed RT issue #27329, clone object now
280 handles undef values correctly.
281 - added tests for this
282 - Corrected anon-class handling so that they
283 will not get reaped when instances still
284 exist which need to reference them. This is
285 the correct behavior, hopefully this is an
286 obscure enough feature that there are not too
287 many work arounds out in the wild.
288 - added tests for this by groditi
289 - updated docs to explain this
292 - load custom metaclasses automatically (thanks groditi)
293 - added tests for this behavior
295 0.37 Sat. March 10, 2007
296 ~~ Many, many documentation updates ~~
299 - added &load_class and &is_class_loaded
300 - added tests and docs for these
302 * Class::MOP::Attribute
303 - default now checks the instance with defined to
304 avoid setting off bool-overloads (found by Carl Franks)
308 - bad name in a test, causing meaningless failuress.
314 - All attribute names are now consistent and follow Perl 6
315 style (prefixed with the sigil, and ! as the twigil for
316 private attrs). This should not affect any code, unless
317 you broke encapsulation, in which case, it is your problem
320 !! Class::MOP::Class::Immutable has been removed
322 * Class::MOP::Method::Constructor
323 - this has been moved out of Class::MOP::Class::Immutable
324 and is a proper subclass of Class::MOP::Method now.
327 - this module now uses Class::MOP::Immutable for the
328 immutable transformation instead of
329 Class::MOP::Class::Immutable.
331 + Class::MOP::Immutable
332 - this module now controls the transformation from a mutable
333 to an immutable version of the class. Docs for this will
334 be coming eventually.
337 0.36 Sun. Nov. 5, 2006
339 - added a few 'no warnings' lines to keep annoying
340 (and meaningless) warnings from chirping during
344 - some more bootstrapping is now done on the new
347 * Class::MOP::Class::Immutable
349 - constructor generation is now handled by
350 the Class::MOP::Method::Constructor class
352 * Class::MOP::Method::Constructor
353 - created this to handle constructor generation
354 in Class::MOP::Class::Immutable
356 * Class::MOP::Attribute
358 - attributes now delegate to the
359 Class::MOP::Method::Accessor to generate
362 * Class::MOP::Method::Accessor
363 - all accessor generation functions from
364 Class::MOP::Attribute have been moved here
366 0.35 Sat. Sept. 30, 2006

378 - added Class::MOP::Method (and its subclasses)
380 - adjusted tests for this
381 - added the Class::MOP::Instance attributes
386 - methods are no longer blessed CODE refs
387 but are actual objects which can be CODE-ified
388 - adjusted tests to compensate
389 - adjusted docs for this
392 - changed how methods are dealt with to
393 encapsulate most of the work into the
394 &get_method_map method
395 - made several adjustments for the change
396 in Class::MOP::Method
397 - &add_attribute now checks if you are adding
398 a duplicate name, and properly removes the
399 old one before installing the new one
400 - added tests for this
401 - adjusted docs for this
403 * Class::MOP::Class::Immutable
404 - added caching of &get_method_map

409 - added filtering capabilities to
410 &list_all_package_symbols
412 0.34 Sat. Aug. 26, 2006
414 - added the %:methods attribute, which like
415 the $:version and such just actually goes
416 to the symbol table to get it's stuff.
417 However, it makes the MOP more complete.
419 - The &create method now requires that all
420 but the package name now is passed in as
421 named parameters. See docs for more info.
422 - updated docs and tests for this
425 - added &dump method to easily Data::Dumper
429 - cleaned up the initialization of attributes
430 which do not store things in the instance
431 - added the %:methods attribute definition to
434 ~ lots of misc. test cleanup
436 0.33 Sat. Aug. 19, 2006

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

446 - reference values (other than CODE refs)
447 are no longer allowed for defaults
448 - added tests for this
450 * Class::MOP::Package

455 ~ lots of misc. documentation cleanup
457 0.32 Sat. Aug. 12, 2006
458 + added Class::MOP::Object so that the
459 metamodel is more complete (and closer
460 to what Perl 6 will probably be).
462 * Class::MOP::Package
463 - refactored entire class, this is now
464 the primary gateway between the metaclass
465 and the Perl 5 symbol table
466 - added many tests for this
467 - this class is now a subclass of
469 - added some tests to reflect this
472 - refactored all symbol table access to
473 use Class::MOP::Package methods instead
476 - adding the $:version attribute in the bootstrap
477 so that Module has a version as an attribute
478 - see comment in Class::MOP for details
479 - added the $:authority attribute to this module
480 as well as an &identifier method, to bring us

502 - added &set_value and &get_value for getting
503 the value of the attribute for a particular
506 0.30 Wed. July 5, 2006
507 ---------------------------------------
508 This is the first version of Class::MOP
509 to introduce the immutable features which
510 will be used for optimizating the MOP.
511 This support should still be considered
512 experimental, but moving towards stability.
513 ---------------------------------------
515 * Created Class::MOP::Class::Immutable
517 * Created the Class::MOP::Package and
518 Class::MOP::Module classes to more
519 closely conform to Perl 6's meta-model
522 - now inherits from Class::MOP::Module
523 - several methods moved to ::Module and
524 ::Package and now inherited
525 - added tests for this
527 * Class::MOP::Instance
528 - added an is_inlinable method to allow other
529 classes to check before they attempt to optimize.
530 - added an inline_create_instance to inline
531 instance creation (of course)
534 - the Class::MOP::Class::*_package_variable
535 methods are all now methods of Class::MOP::Package
536 and called *_package_symbol instead. This is
537 because they are now more general purpose symbol
538 table manipulation methods.
540 0.29_02 Thurs. June 22, 2006
541 ++ DEVELOPER RELEASE ++
543 - small change in &create so that it behaves

548 ++ DEVELOPER RELEASE ++
549 - This release works in combination with
550 Moose 0.09_01, it is a developer release

599 - attribute slot initialization is now the responsibility
600 of the attribute itself, and construct_instance now
601 delegates appropriately
603 * Class::MOP::Attribute
604 - attribute slot initialization is now the responsibility
605 of the attribute itself, so we added a method for it
606 called initialize_instance_slot

610 initialize_instance_slot method
612 0.24 Tues. April 11, 2006

627 - adjusted all /example files to comply
629 0.22 Mon. March 20, 2006

635 0.21 Wed. March 15, 2006
637 - fixed issue where metaclasses are reaped from
638 our cache in global destruction, and so are not

684 shallow clone (see docs for more details)
685 - added docs and tests
687 0.10 Tues Feb. 14, 2006
688 ** This release was mostly about writing more tests and
689 cleaning out old and dusty code, the MOP should now
690 be considered "ready to use".
692 - adding more tests to get coverage up a little higher,
693 mostly testing errors and edge cases.
694 - test coverage is now at 99%
697 - no longer optionally exports to UNIVERSAL::meta or
698 creates a custom metaclass generator, use the
699 metaclass pragma instead.
702 - fixed a number of minor issues which came up in the
703 error/edge-case tests
705 * Class::MOP::Attribute

715 metaclass a little more straightforward
718 - clean up bootstrapping to include more complete
719 attribute definitions for Class::MOP::Class and
720 Class::MOP::Attribute (accessors, readers, writers,
721 etc.) ... it is redundant, but is useful meta-info
725 - fixing minor meta-circularity issue with &meta, it
726 is now more useful for subclasses
727 - added &get_attribute_map as an accessor for the
728 hash of attribute meta objects
729 - &compute_all_applicable_attributes now just returns
730 the attribute meta-object, rather than the HASH ref
731 since all the same info can be gotten from the
732 attribute meta-object itself
733 - updated docs & tests to reflect
734 - added &clone_instance method which does a deep clone
735 of the instance structure created by &construct_instance
736 - added docs & tests for this
737 - added Clone as a dependency
738 - added &new_object and &clone_object convience methods to
739 return blessed new or cloned instances
740 - they handle Class::MOP::Class singletons correctly too
741 - added docs & tests for this
742 - cleaned up the &constuct_class_instance so that it behaves
743 more like &construct_instance (and managed the singletons too)
744 - added the &check_metaclass_compatibility method to make sure
745 that metaclasses are upward and downward compatible.
746 - added tests and docs for this

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

770 - some documentation suggestions from #perl6
772 * Class::MOP::Attribute

795 - moving examples from t/lib/* to examples/*
796 - adding POD documentation to the examples
798 0.01 Thurs Feb. 2, 2006
