Class-MOP - Changes

Revision history for Perl extension Class-MOP.

1.12 Mon, Jan 3, 2011

Remove usage of undocumented Package::Stash APIs from the tests. This prevents the tests from failing on Package::Stash >= 0.18.

1.11 Sun, Oct 31, 2010

Replace use of Test::Exception with Test::Fatal. (Karen Etheridge and Dave Rolsky)

1.10 Mon, Oct 18, 2010

Lots of fixes for edge cases with anon classes. (doy)

1.09 Tue, Oct 5, 2010

[ENHANCEMENTS]

It's now possible to tell Class::MOP::Class->create and the metaclass pragma to not install a 'meta' method into classes they manipulate, or to install one under a different name. (doy)
Reinitializing a metaclass no longer removes the existing method and attribute objects (it instead fixes them so they are correct for the reinitialized metaclass). (doy)
All 'meta' methods created by Class::MOP are now of the class Class::MOP::Method::Meta. This is overridable at the metaclass layer. (doy)

[OTHER]

Use get_or_add_package_symbol when we intend for it to autovivify, in preparation for changes in Package::Stash. (doy)
We now use Module::Install::AuthorRequires to force authors to run all tests, just like we do for Moose. (sartak)

1.08 Mon, Sep 13, 2010

[BUG FIXES]

The get_method_list and getlocal_methods methods blew up in the face of subroutine stubs. (Goro Fuji)

1.07 Tue, Aug 25, 2010

[BUG FIXES]

Fix a mysterious error reported by Piers Cawley. The error showed up as "Can't use an undefined value as a symbol reference at /usr/local/lib/perl/5.10.1/Class/MOP/Mixin/HasMethods.pm line 167." (Dave Rolsky)

1.06 Sun, Aug 23, 2010

[BUG FIXES]

Version 1.05 no longer reported constants as methods, except with Perl 5.8.x, and doing so in 5.8.x caused test failures. Constants are now expected to be reported as methods, and we explicitly test this. (Dave Rolsky)

1.05 Sun, Aug 22, 2010

[ENHANCEMENTS]

Refactorings and improvements to how defaults are handled, particularly for inlined code (doy).
Optimizations that should help speed up compilation time (Dave Rolsky).

1.04 Tue, Jul 25, 2010

[ENHANCEMENTS]

Class::MOP::Deprecated now uses Package::DeprecationManager internally. Deprecation warnings are now only issued once for each calling package, which cuts down on noise. When importing Class::MOP::Deprecated, the request API version should now be passed in the "-api_version" flag. However, the old "-compatible" flag will continue to work. (Dave Rolsky)

1.03 Sat, Jun 5, 2010

[ENHANCEMENTS]

Make CMOP::Package a thin wrapper around Package::Stash (doy).

1.02 Thu, May 20, 2010

[API CHANGES]

Packages and modules no longer have methods - this functionality was moved back up into Class::MOP::Class (doy).

[ENHANCEMENTS]

Metaclass incompatibility checking now checks all metaclass types. (doy)
Class::MOP can now do simple metaclass incompatibility fixing: if your class's metaclass is a subclass of your parent class's metaclass, it will just use the parent class's metaclass directly. (doy)

1.01 Thu, May 6, 2010

[NEW FEATURES]

is_class_loaded, load_class and load_first_existing_class now allow specifying a minimum required version (Florian Ragwitz).

[BUG FIXES]

The __INSTANCE__ parameter to Class::MOP::Class::new_object now enforces that the passed in reference is blessed into the correct class (by dying if it's not) (doy, jhallock).

1.00 Thu, Mar 25, 2010

[GRRR< FUCKING STEVAN@]

Re-release 0.99 as 1.00.

0.99 Thu, Mar 25, 2010

[DOCUMENTATION]

Fix typo in Class::MOP::Attribute (Franck Cuny).

0.98 Mon, Jan 18, 2010

[ENHANCEMENTS]

Added Class::MOP::Class->rebless_instance_back, which does the inverse of rebless_instance (doy, rafl).

0.97_01 Mon, Jan 4, 2010

[ENHANCEMENTS]

Internal refactorings to move shared behavior into new "mixin" classes. This made adding some new features to Moose much easier. (Dave Rolsky)

0.97 Fri, Dec 18, 2009

No code changes, just packaging fixes to make this distro installable.

0.96 Fri, Dec 18, 2009

tests
- Fixed t/082_get_code_info.t so it passes with bleadperl. (Dave Rolsky)
- Add XS & C files to no tabs check (Dave Rolsky)
- Convert all tests to done_testing. (Florian Ragwitz)

0.95 Wed, Nov 19, 2009

Class::MOP
- Make is_class_loaded without any arguments fail loudly (Florian Ragwitz).
- Make load_class throw more standard error messages when loading single modules (nothingmuch).
Class::MOP::Package
- Stop add_method from behaving differently under the debugger (Florian Ragwitz).
Class::MOP::Class
Class::MOP::Package
- Any method which takes a method name as an argument now allows names which are false (like "0"), but the name must be defined and not be an empty string. (Dave Rolsky)
Class::MOP::Class
- Deprecated get_attribute_map as a public method. You can use a combination of get_attribute_list and get_attribute instead. (Dave Rolsky)

0.94 Tue, Sep 22, 2009

Class::MOP::Attribute
- Introduce set_raw_value and get_raw_value, side effect free variants of {get,set}value. These don't do anything useful in Class::MOP but have different behavior that setvalue and get_value for Moose attributes. (nothingmuch)

0.93 Tue, Sep 15, 2009

Class::MOP
- The load_class function just returns true, since it's return value was confusing (either a metaclass object or a class name). It either loads a class or dies trying. In the future, this may change to not return anything, since there's no point in checking its return value. Addresses RT #45883. (Dave Rolsky)
Class::MOP::Class::Trait::Immutable
- When throwing an error because of an immutable method, include that method's name. Addresses RT #49680. (Shawn M Moore)
Class::MOP::Package
- Adding the same sub reference to multiple packages failed to update the method map properly. RT #48985. Reported by Paul Mooney. (Dave Rolsky)
- The get_method_map method is now private (and called as fullmethod_map or methodmap). The public version is available as a deprecated method. (Dave Rolsky)

0.92_01 Thu, Sep 10, 2009

Class::MOP::Package
- Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)
Class::MOP
- Make sure XS code handles magical scalars correctly. (Goro Fuji)
Class::MOP::Class
- Documented the immutable_options method, which is useful if you need to make a class mutable temporarily, and then nede to restore immutability. (Dave Rolsky)
Many modules
- Deprecated features have been moved to their own module, Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)

0.92 Thu Aug 13, 2009

Class::MOP::Class
Class::MOP::Package
- Move get_method_map and its various scaffolding into Package. (hdp)
Class::MOP::Method
- Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as the first argument, rather than just a coderef. (doy)
Class::MOP::Attribute
Class::MOP::Class
- Allow attribute names to be false (while still requiring them to be defined). (rafl)

0.91 Wed Jul 29, 2009

Class::MOP::Method::Wrapped
- Fixing variable usage issues with the patch from previous version, not properly using lexicals in the for loops. (stevan)

0.90 Tue Jul 21, 2009

Japan Perl Association has sponsored Goro Fuji to improve startup performance of Class::MOP and Moose. These enhancements may break backwards compatibility if you're doing (or using) complex metaprogramming, so, as always, test your code! http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html

Class::MOP::Class
XS
- Anonymous classes were not completely destroyed when they went out of scope, leading to a memory leak. RT #47480. (Goro Fuji).
Class::MOP::Class
- The get_method, has_method, and add_method methods no longer use get_method_map. Method objects are instantiated lazily. This significantly improves Class::MOP's load time. (Goro Fuji)
All classes
- Inline fewer metaclass-level constructors since the ones we have are perfectly fine. This reduces the number of string evals. (Goro Fuji)
Class::MOP::Method::Wrapped
- If a method modifier set $_, this caused the modifier to blow up, because of some weird internals. (Jeremy Stashewsky)

0.89 Fri Jul 3, 2009

Class::MOP::Class
Class::MOP::Class::Immutable::Trait
- Made the Trait act like a role with a bunch of "around" modifiers, rather than sticking it in the inheritance hierarchy. This fixes various problems that caused with metaclass compatibility, which broke Fey::ORM.
Class::MOP::Method
- Allow a blessed code reference as the method body. Fixes a problem interaction with MooseX::Types. (ash)
Class::MOP::Instance
- add inline version of rebless_instance_structure. (doy)
- change inline_slot_access to use single quotes (gphat)

0.88 Tue, Jun 23, 2009

Class::MOP::Class
- Moved the __INSTANCE__ parameter to constructinstance from Moose to here. (doy)
- Fixed some issues involving metaclasses of metaclasses and immutability. (doy)

0.87 Sun, Jun 21, 2009

Various
- Made sure to always local-ize $@ and $SIG{__DIE__} before calling an eval. Fixes RT #45973.
Class::MOP::Class
- Synced docs about immutability with the current reality (which changed back in 0.82_01)
- Removed the immutable_transformer method, which had been returning undef since 0.82_01 anyway.
Tests
- Got rid of tests which needed Moose and improved testing of constructor/destructor inlining warnings. Fixes RT #47119.

0.86 Tue, Jun 16, 2009

Class::MOP::Class
- If you redefined a subroutine at runtime and then wrapped it with a method modifier, the modifier could in some cases wrap the original version of the subroutine. Fixes RT #46957.
Class::MOP::Class
- make_immutable issues a warning instead of overriding an existing DESTROY method (Dylan William Hardison). Fixes RT #46854.

0.85 Sat, Jun 6, 2009

Class::MOP::Attribute
- Allow default values to be Class::MOP::Methods. (Florian Ragwitz)
- Test the above. (Rhesa Rozendaal)
- Tweak original commit so the intent matches the accepted behavior (Nicholas Perez)
Class::MOP
- Localize $SIG{__DIE__} inside tryload_one_class (Sartak)
Class::MOP::Class
- Add direct_subclasses method (Sartak)
  - Tests for subclasses and direct_subclasses (Sartak)
- subname is no longer used unconditionally in add_method, but only if the code reference's name is '__ANON__' (nothingmuch)
- Add a hook for superclassesupdated (Sartak)
Class::MOP::Method
- Remove long, old warning about possibly outdated modules (Sartak)

0.84 Tue, May 12, 2009

Makefile.PL
- Depend on Text::Exception 0.27 to avoid failing tests ond old versions (rafl)
Class::MOP
- Made is_class_loaded a little stricter. It was reporting that a class was loaded if it merely had an @ISA variable in its stash. Now it checks that the @ISA var has elements in it.
- Deprecate in_global_destruction and subname re-exporting (perigrin & Sartak)
Class::MOP::Class
- Explicitly use Devel::GlobalDestruction and Sub::Name (perigrin)
Class::MOP::Package
- Disable prototype mismatch warnings for add_package_symbol. (Florian Ragwitz)
Tests
- Add test for finding methods from $meta->name->meta before immutable, (t0m)

0.83 Mon, April 27, 2009

Class::MOP::Class
- Fix segfault when calling get_method_map on a metaclass for an empty package (doy)

0.82_02 Fri, April 24, 2009

Class::MOP::Method::Inlined
- Don't inline if the expected method is not defined at all (happens with e.g. Moose::Object::new is the expected method due to an overridden name)
Tests
- Some tests were trying to load Class::MOP::Immutable, which was removed in 0.8201.

0.82_01 Thu, April 23, 2009

Class::MOP::Immutable (and others)
- Refactor the immutability system to use a pre-defined class for the immutable metaclass of Class::MOP::Class::Immutable::$class
- Rather than generating methods into this class every time, use a Trait (basic mixin) to supply the cached methods
- Remove the hack that returns the mutable metaclass for metacircularity in order to provide consistent meta-metaclasses for the Moose compatibility handling code (mst broke it, nothingmuch fixed it)

0.82 Mon, April 20, 2009

Various
- The deprecation wrappers for some renamed methods were not passing arguments to the new method. (nothingmuch)
Class::MOP::Immutable
- Warn during immutablization if the local class provides its own constructor, to parallel the warning in Moose when a superclass provides its own constructor (doy)

0.81 Tue, April 7, 2009

Class::MOP
Class::MOP::Class
Class::MOP::Instance
Class::MOP::Attribute
Class::MOP::Method::Accessor
Class::MOP::Method::Constructor
- Include stack traces in the deprecation warnings introduced in 0.80_01. (Florian Ragwitz)
MOP.xs
- Avoid c compiler warnings by declaring some unused function arguments. (Florian Ragwitz)

0.80_01 Sun, April 5, 2009

Makefile.PL
- Make sure to preserve any compiler flags already defined in Config.pm. Patch by Vincent Pit. RT #44739.
Many methods have been renamed with a leading underscore, and a few have been deprecated entirely. The methods with a leading underscore are considered "internals only". People writing subclasses or extensions to Class::MOP should feel free to override them, but they are not for "public" use.
- Class::MOP::Class
  - construct_class_instance => constructclass_instance (use new_object)
  - construct_instance => constructinstance (use new_object)
  - check_metaclass_compatibility => checkmetaclass_compatibility
  - create_meta_instance => createmeta_instance (use get_meta_instance)
  - clone_instance => cloneinstance (use clone_object)
  - compute_all_applicable_methods is deprecated, use get_all_methods
  - compute_all_applicable_attributes is deprecated, use get_all_attributes
- Class::MOP::Instance
  - bless_instance_structure is deprecated and will be removed in a future release
- Class::MOP::Module
  - create has been renamed to instantiatemodule. This method does not construct an object, it evals some code that creates the relevant package in Perl's symbol table.
- Class::MOP::Method::Accessor
  - initialize_body => initializebody (this is always called when an object is constructed)
  - /(generate_.*method(?:inline)?)/ => '_' . $1
- Class::MOP::Method::Constructor
  - initialize_body => initializebody (this is always called when an object is constructed)
  - /(generate_constructor_method(?:inline)?)/ => '' . $1
  - attributes => attributes
  - metainstance => metainstance

0.80 Wed, April 1, 2009

Class::MOP::*
- Call user_class->meta in fewer places, with the eventual goal of allowing the user to rename or exclude ->meta altogether. Instead uses Class::MOP::class_of. (Sartak)
Class::MOP
- New class_of function that should be used to retrieve a metaclass. This is unlike get_metaclass_by_name in that it accepts instances, not just class names. (Sartak)
Class::MOP
- load_first_existing_class didn't actually load the first existing class; instead, it loaded the first existing and compiling class. It now throws an error if a class exists (in @INC) but fails to compile. (hdp)
Class::MOP
Class::MOP::Class
- we had some semi-buggy code that purported to provide a HAS_ISAREV based on whether mro had get_isarev (due to an oversight, it always returned 1). Since mro and MRO::Compat have always had get_isarev, HAS_ISAREV was pointless. This insight simplified the subclasses method by deleting the pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)

0.79 Fri, March 29, 2009

No changes from 0.78_02.

0.78_02 Thu, March 26, 2009

Class::MOP::Class
Class::MOP::Immutable
- A big backwards-incompatible refactoring of the Immutable API, and the make_immutable/make_mutable pieces of the Class API. The core __PACKAGE__->meta->make_immutable API remains the same, however, so this should only affect the most guts-digging code.
XS code
- The XS code used a macro, XSPROTO, that's only in 5.10.x. This has been fixed to be backwards compatible with 5.8.x.
Class::MOP::Class
- Add a hook for rebless_instance_away (Sartak)
- Use blessed instead of ref to get an instance's class name in rebless_instance. (Sartak)

0.78_01 Wed, March 18, 2009

Class::MOP::*
- Revised and reorganized all of the API documentation. All classes now have (more or less) complete API documentation.
Class::MOP::Class
Class::MOP::Instance
- Reblessing into a package that supports overloading wasn't properly adding overload magic to the object due to a bug in (at least) 5.8.8. We now use $_[1] directly which seems to set the magic properly. (Sartak)
Class::MOP::Attribute
- The process_accessors method is now private. A public alias exists (and will stick around for a few releases), but it warns that calling the public method is deprecated.
Class::MOP::Method::Generated
- Removed the new and _new methods, since this is an abstract base class, and all existing subclasses implement their own constructors.
MOP.xs
- Stop is_class_loaded from thinking a class is loaded if it only has an empty GV (Florian Ragwitz).
  - Add a test for this (Yappo).
- Refactor get_all_package_symbols to allow short-circuiting (Florian Ragwitz).
  - Use this in is_class_loaded (Florian Ragwitz).
- Stop segfaulting when trying to get the name from a sub that's still being compiled (Florian Ragwitz).
  - Add tests for this (Florian Ragwitz).
- Prefix all public symbols with "mop_" (Florian Ragwitz).
- Clean up and simplify prehashing of hash keys (Florian Ragwitz).
- Simplify creating simple xs reader methods (Florian Ragwitz).
- Make everything compile with c++ compilers (Florian Ragwitz).
- Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).
Tests
- Remove optional test plans for tests depending on Sub::Name as we have a hard dependency on Sub::Name anyway (Florian Ragwitz).
Makefile.PL
- Rebuild all c code if mop.h has changed (Florian Ragwitz)

0.78 Mon, February 23, 2009

No changes from 0.77_01

0.77_01 Sun, February 22, 2009

Everything
- This package now requires its XS components. Not using Sub::Name lead to different behavior and bugginess in the pure Perl version of the code. A Moose test would fail when run against the pure Perl version of this code.
Class::MOP::Instance
- The inline_* methods now quote attribute names themselves, and don't expect to receive a quoted value.

0.77 Sat, February 14, 2009

MOP.xs
- Avoid assertion errors on debugging perls in is_class_loaded (Florian Ragwitz)
Class::MOP
- Fixed various corner cases where is_class_loaded incorrectly returned true for a class that wasn't really loaded. (Dave Rolsky)
Class::MOP::Class
- Add get_all_method_names (Sartak)
- Add a wrapped_method_metaclass attribute (Florian Ragwitz)
Class::MOP::Package
- Disable deprecated get_all_package_symbols in list context. (Florian Ragwitz)
Makefile.PL
- Make sure we generate a BSD-compatible Makefile (Florian Ragwitz)
Class::MOP::Class
- The misspelled "check_metaclass_compatability" method we've kept around for backwards compatibility will be removed in a near future release. You've been warned.

0.76 Thu, January 22, 2009

Class::MOP::Method::Generated
- Added new private methods to support code generation, which are being used by Moose and can be used by MooseX authors. (mst)
- Generated methods are now generated with a #line directive reflecting the source of the generated method. (nothingmuch)
Class::MOP::Class
- Clarified documentation of methods that return Class::MOP::Method objects. (doy)
Class::MOP
- Clarified documentation of the metaclass cache methods. (Sartak)
Tests
- Add test showing how the xs Class::MOP::is_class_loaded can be made to operate differently to the pure perl version (t0m)

0.75 Wed, December 31, 2008

Class::MOP::Class
- A class that was made immutable and then mutable could end up sharing an immutable transformer object (Class::MOP::Immutable) with other classes, leading to all sorts of odd bugs. Reported by t0m. (Dave Rolsky)

0.74 Tue, December 25, 2008

MOP.xs
- Add an xs implementation of Class::MOP::is_class_loaded (closes RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
- Changed internals to make prehashing of hash keys easier and less error-prone. (Florian Ragwitz)
Class::MOP::Class
- Fix documentation to show that around modifiers happen on both sides of the modified method. (Dave Rolsky)

0.73 Tue, December 16, 2008

MOP.xs
- Don't use Perl_mro_meta_init. It's not part of the public perl api. Fixes failures to build on Win32 (RT #41750). (Florian Ragwitz)
t/082_get_code_info.t
- Add $^P &= ~0x200; (per Ovid's suggestion) in order to not munger anonymous subs when under -d and so making the tests succeed in that case.

0.72 Mon, December 8, 2008

Class::MOP::Package
- Pass options to new, so subclass' attributes can be initialized (Sartak)
Class::MOP::Method
- In the docs, indicate that packagename and name are required when calling ->wrap (Stefan O'Rear)

0.71_02 Fri, December 5, 2008

Class::MOP::Immutable
- Added a new attribute, inlined_constructor, which is true if the constructor was inlined.
Class::MOP::Package
- Make get_all_package_symbols return a hash ref in scalar context and deprecate calling it in list context with a warning. (Florian Ragwitz)
MOP.xs
- Various improvements and refactoring, making things more robust and easier to maintain. (Florian Ragwitz)

0.71_01 Wed, December 3, 2008

Class::MOP::Method
- Add an "execute" method to invoke the body so we can avoid using the coderef overload (Sartak)
Class::MOP::Immutable
- When we memoize methods, get their results lazily to remove some compile-time cost (Sartak)
- Small speedup from eliminating several method calls (Sartak)
Class::MOP::Class
- Some small internal tweaks to try to reduce the number of times we call get_method_map when bootstrapping the MOP. This might make loading Class::MOP (and Moose) a little faster. (Dave Rolsky)
- Implemented an optional XS version of get_method_map. Mostly taken from a patch by Goro Fuji (rt.cpan.org #41080), with help form Florian Ragwitz. (Dave Rolsky)
- Make the behaviour of of get_all_package_symbols (and therefore get_method_map) consistent for stub methods. Report and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)

0.71 Wed November 26, 2008

Class::MOP::Class
Class::MOP::Module
- Actual package creation has moved upward from Class to Module so that Moose roles can share the code (Sartak)

0.70_01 Mon, November 19, 2008

Class::MOP
- Fixes for failures with blead (Florian Ragwitz)
- Silenced compiler warnings (Florian Ragwitz)

0.70 Fri, November 14, 2008

Class::MOP
- Fixed an odd corner case where the XS version of get_all_package_symbols could cause a segfault. This only happened with inlined constants in Perl 5.10.0 (Florian Ragwitz)

0.69 Fri, November 7, 2008

Class::MOP::Method::Wrapped
- Added introspection methods for method modifiers (Dave Rolsky)

0.68 Fri October 24, 2008

Class::MOP
- Make load_class require by file name instead of module name. This stops confusing error messages when loading '__PACKAGE__'. (Florian Ragwitz)
- Add load_one_class_of function to enable you to load one of a list of classes, rather than having to call load_class multiple times in an eval. (t0m)

0.67 Tue October 14, 2008

Class::MOP::Class
- Call a method on the class after setting the superclass list so that we can get Perl to detect cycles before MRO::Compat spirals into an infinite loop (sartak)
  - Reported by Schwern, [rt.cpan.org #39001]
- In create(), pass unused options on to initialize()
  - added test for this

0.66 Sat September 20, 2008

!! This release has an incompatible change regarding !!

introspection of a class's method with Class::MOP::Class !!

Tests and XS
- We (us maintainers) now run all tests with XS and then without XS, which should help us catch skew between the XS/pure Perl code. (Dave Rolsky)
Class::MOP::Class ! The alias_method method has been deprecated. It now simply calls add_method instead. There is no distinction between aliased methods and "real" methods.

        This means that methods added via alias_method now show up as
        part of the class's method list/map. This is a backwards
        incompatible change, but seems unlikely to break any
        code. Famous last words. (Dave Rolsky)

Class::MOP::Class
- Fixed the spelling of "compatibility", but we still have a "check_metaclass_compatability" method for backwards compatibility.

0.65 Mon September 1, 2008

For those not following the series of dev releases, the changes from 0.64 from 0.65 can mostly be summed up as a lot performance improvements by nothingmuch, including new optional XS versions of some methods. Also, Class::MOP now works without any XS modules, for sad systems without a compiler.

Class::MOP::Method
- Added name and package_name XS accessors, and make sure all the XS and Perl versions work the same way. (Dave Rolsky)
MOP.xs
- The XS versions of various methods just returned undef when called class methods, rather than dying like the pure Perl versions. (Dave Rolsky)

0.64_07 Fri August 29, 2008

Class::MOP
- Silenced warnings that managed to break Moose tests when XS was loaded. (Dave Rolsky)
- Some XS versions of methods were ignored because of typos in MOP.xs. (Dave Rolsky)

0.64_06 Mon August 25, 2008

Class::MOP (MOP.xs)
- Another MS VC++ fix, cannot declare a variable in the middle of a scope (Taro Nishino).

0.64_05 Sun August 24, 2008

Class::MOP
- None of the dev releases actually loaded the XS properly, but we silently fell back to the pure Perl version of the code. (Dave Rolsky)
Class::MOP (MOP.xs)
- Replaced some code that used functions not available on Visual C++ with some Perl XS API bits (Dave Rolsky).

0.64_04 Sat August 23, 2008

Class::MOP::Class
- Workaround a bug in 5.8.1's goto sub (nothingmuch)
pod.t and pod_coveraget.t
- These are no longer shipped with the tarball because of bogus failures from CPAN testers. (Dave Rolsky)

0.64_03 Thu August 21, 2008

Class::MOP::Package
- Some (legit) code was misparsed by earlier 5.8.x releases. (nothingmuch)
Class::MOP
- Fix a constant in void context warning (nothingmuch)

0.64_02 Thu August 21, 2008

Makefile.PL and Class::MOP
- Explicitly require Perl 5.8.0+ (Dave Rolsky)
Makefile.PL
- Add missing prereqs that got lost in the switch away from Module::Install.
Class::MOP::Instance
- New method - get_all_attributes (nothingmuch)

0.64_01 Wed August 20, 2008

Makefile.PL
- We now check to see if you have a compiler. If you don't, the module installs without some XS bits, but will work the same as with XS. This should make it easier to install on platforms without a compiler (like Windows). (Dave Rolsky)
many modules
- Perl 6 style attribute naming replaced with sane style ('methods', not '%!methods'). These changes should not impact any existing API uses. (nothingmuch).
many modules
- Quite a number of optimizations based on profiling, including allowing constructors to take hash references instead of hashes, duplicating some frequently used code in XS, and making constructors immutable. These changes should not impact any existing API uses. (nothingmuch)
Many modules
- Constructors now respect the meta attributes of their subclasses, facilitating MOP extensibility. More related changes will happen in the next several releases. (nothingmuch)
Class::MOP::Class
- New method - get_all_methods, replaces the deprecated compute_all_applicable_methods. get_all_attributes provided for consistency (nothingmuch)
- New method - wrap_method was refactored out of get_method_map (nothingmuch)
- New API for meta instance invalidation - invalidate_meta_instance, invalidate_meta_instances, add_dependent_meta_instance, remove_dependent_meta_instance, called automatically when attribute definitions change and allows notification of dependent subclasses. (nothingmuch)

0.64 Sun August 3, 2008

Class::MOP::Immutable
- fixing subtle edge case in immutable when you call ->meta (stevan)
- clean up option processing (nothingmuch)

elsewhere
- better error messages (sartak and Dave Rolsky)

0.62 Wed June 18, 2008

in is_class_loaded, recognize scalar references (as opposed to globs) in the symbol table as methods (these are optimized constant subs)

0.61 Fri. June 13, 2008

Okay, lets give this another try and see if PAUSE recognizes it correct this time.

0.60 Thurs. Jun 12, 2008

Fixed a version number issue by bumping all modules to 0.60.

0.59 Thurs. Jun 12, 2008

!! Several fixes resulting in yet another 25-30% speedup !!

Class::MOP::Class
- now stores the instance of the instance metaclass to avoid needless recomputation and deletes it when the cache is blown
- introduce methods to query Class::MOP::Class for the options used to make it immutable as well as the proper immutable transformer. (groditi)
Class::MOP::Package
- {add, has, get, remove}packagesymbol all now accept a HASH ref argument as well as the string. All internal usages now use the HASH ref version.
Class::MOP
- MOP.xs does sanity checks on the coderef to avoid a segfault
- is_class_loaded check now uses code that was improved in Moose's ClassName type check (Sartak)
- nonsensical (undef, empty, reference) class names now throw a more direct error in load_class (Sartak)
  - tests for this and other aspects of load_class (Sartak)
Class::MOP Class::MOP::Class Class::MOP::Method Class::MOP::Method::Wrapped Class::MOP::Attribute
- switched usage of reftype to ref because it is much faster

0.58 Thurs. May 29, 2008

(late night release engineering)--

fixing the version is META.yml, no functional changes in this release

0.57 Wed. May 28, 2008

- streamlining &initialize somewhat, since it gets called so much
Class::MOP::Package
- made {get, has}packagesymbol not call &namespace so much
- inlining a few calls to &name with direct HASH access key access
- added get_all_package_symbols to fetch a HASH of items based on a type filter similar to list_all_package_symbols
  - added tests for this
Class::MOP::Method Class::MOP::Method::Constructor Class::MOP::Method::Generated Class::MOP::Method::Accessor
- added more descriptive error message to help keep people from wasting time tracking an error that is easily fixed by upgrading.
Class::MOP::Immutable
- Don't inline a destructor unless the user actually needs one

- all these classes are now bootstrapped properly and now store the package_name and name attributes correctly as well

~ Build.PL has been removed since the Module::Install support has been removed

0.55 Mon. April 28, 2008

All classes now have proper C3 MRO support
- added MRO::Compat as a dependency to allow for the C3 MRO support to Just Work in all perl versions

- added two XS functions (thanks konobi)
  - get_code_info($code) which replaces all the B fiddling we were doing with faster/leaner XS level fiddling
  - check_package_cache_flag($pkg_name) which returns the PL_sub_generation variable to be used to help manage method caching.
    
    NOTE

Class::MOP::Class
- added the &subclasses method (thanks rlb)
- added the update_package_cache_flag and reset_package_cache_flag which help keep track of when we need to re-fetch the method map.

Class::MOP::Attribute
- added the get_read_method_ref and get_write_method_ref methods which allow you to retrieve a CODE ref which can always be used to read or write an attribute.

- Fix error message on confess (groditi)

0.44 Thurs. Nov. 13, 2007

Tests for new predicate behavior (and corrections to old tests) (groditi)

*examples/

Update ArrayRef based class example to work with predicate changes

0.42 Mon. July 16, 2007

!!! Horray for mst, he fixed it !!!

Class::MOP::Package
- alter symbol table handling to deal with 5.8.x and 5.9.x
t/
- Get rid of the crappy workaround from 0.40/41

0.41 Sun. July 15, 2007

t/ Arghh!!! My TODO test didn't work, so I handle it manually now so that people can use this with 5.9.5/bleadperl without issue.

0.40 Tues, July 3, 2007

t/ ~ marked a test in 003_methods.t as TODO for perl 5.9.5 (this test is irrelvant to the module functioning on 5.9.5 for the most part anyway)

0.39 Mon. June 18, 2007

Class::MOP::Immutable
- added make_metaclass_mutable + docs (groditi)
- removed unused variable
- added create_immutable_transformer necessary for sane overloading of immutable behavior
  - tests for this (groditi)
Class::MOP::Class
- Immutability can now be undone, added make_mutable + tests + docs (groditi)
- Massive changes to the way Immutable is done for details see comments next to make_immutable This fixes a bug where custom metaclasses broke when made immutable. We are now keeping one immutable metaclass instance per metaclass instead of just one to prevent isa hierarchy corruption. Memory use will go up, but I suspect it will be neglible.
  - New tests added for this behavior. (groditi)

0.38 Thurs. May 31, 2007

~~ More documentation updates ~~

Class::MOP::Package
- we now deal with stub methods properly

- Corrected anon-class handling so that they will not get reaped when instances still exist which need to reference them. This is the correct behavior, hopefully this is an obscure enough feature that there are not too many work arounds out in the wild.
  - added tests for this by groditi
  - updated docs to explain this
metaclass
- load custom metaclasses automatically (thanks groditi)
  - added tests for this behavior

0.37 Sat. March 10, 2007

Class::MOP::Attribute
- default now checks the instance with defined to avoid setting off bool-overloads (found by Carl Franks)

0.37_002

/t
- bad name in a test, causing meaningless failuress. No other changes.

0.37_001

~~ GLOBAL CHANGES ~~

All attribute names are now consistent and follow Perl 6 style (prefixed with the sigil, and ! as the twigil for private attrs). This should not affect any code, unless you broke encapsulation, in which case, it is your problem anyway.

!! Class::MOP::Class::Immutable has been removed

Class::MOP::Method::Constructor
- this has been moved out of Class::MOP::Class::Immutable and is a proper subclass of Class::MOP::Method now.
Class::MOP::Class
- this module now uses Class::MOP::Immutable for the immutable transformation instead of Class::MOP::Class::Immutable.

+ Class::MOP::Immutable

this module now controls the transformation from a mutable to an immutable version of the class. Docs for this will be coming eventually.

0.32 Sat. Aug. 12, 2006

+ added Class::MOP::Object so that the

      metamodel is more complete (and closer
      to what Perl 6 will probably be).

0.30 Wed. July 5, 2006

This is the first version of Class::MOP to introduce the immutable features which will be used for optimizating the MOP. This support should still be considered experimental, but moving towards stability.

Created Class::MOP::Class::Immutable
Created the Class::MOP::Package and Class::MOP::Module classes to more closely conform to Perl 6's meta-model
Class::MOP::Class
- now inherits from Class::MOP::Module
- several methods moved to ::Module and ::Package and now inherited
  - added tests for this
Class::MOP::Instance
- added an is_inlinable method to allow other classes to check before they attempt to optimize.
- added an inline_create_instance to inline instance creation (of course)

** API CHANGE **

the Class::MOP::Class::*packagevariable methods are all now methods of Class::MOP::Package and called *packagesymbol instead. This is because they are now more general purpose symbol table manipulation methods.
