Revision history for Perl extension Class::Prototyped

1.11 Tue Dec 18 2007

• Fixed error in synopsis (C::P->new is correct, C::P::new isn't). Thanks to Matthew Browning.
• Added @$isa=@$isa changes to workaround @ISA issues in 5.10.0.

1.10 Tue Mar 15 2005

• Merlyn strongly suggested that I unify the behavior of new() for named classes and un-named objects. After much discussion, I concurred. This is a BACKWARDS INCOMPATIBLE change. Hopefully it will not affect too much code. In 1.01, calling new() on an un-named object was identical to calling Class::Prototyped->new(). In 1.10, calling new() on an un-named object ALSO adds 'class*' as a slot pointing to the original object. This also necessitated a change to clone.
• Two new Class::Prototyped methods are added: clonePackage (a cross between clone and newPackage) and newCore (implements core object instantiation behavior). If you implement either method in any of your Class::Prototyped code, there will be problems!
• Fixed a bug in Class::Prototyped::Mirror::Normal::new that affected superable calls to C::P objects following reflection on a non-C::P object blessed into a C::P class.

1.01 Sat Mar 20 2004

• Now using create_makefile_pl => 'traditional' because passthrough doesn't seem to work with subclassing (Thanks merlyn for reporting this)

1.00 Sat Mar 20 2004

• Now using Module::Build!
• Now generating PPMs as well!
• Long live Module::Build!

0.98 Mon Jan 19 2004

• Distribution updated to migrate Class directory into lib and update Manifest and Makefile.pl.

0.97 Mon Sep 22 2003

• Slot attribute 'profile' modified to support recording calling location.

0.96 Tue Sep 16 2003

• More POD changes and updates

0.95 Mon Sep 8 2003

• Minor changes to POD
• Minor changes to test code

0.94 Thu Jan 9 2003 (not released)

• Rationalized and codified attribute support
• Moved addSlots parsing/checking code into separate method from implementation, thus eating up a good chunk of the optimizations. On the other hand, this improved the handling of error conditions in addSlots and exposes the parsing to external code. In addition, implementation of slots was moved into separate method so that the slots could be parsed, then modified in parsed form, and then passed to the implementor.
• Cleared up bug that caused infinite recursion when non-C::P structured objects that inherit from C::P from call $self->reflect->super(). Using reflect on objects (not classes) that are not C::P structured is still fraught with peril, but super is at least safe.
• Added support for defaultAttributes.
• Unfortunately, we lost the performance battle. Package creation is running slightly faster than in 0.90. Package instantion from subs is running much faster. addSlots, however, is running around 20% slower (it's a hard call because there are both constant and proportional terms). Individual calls appear to be slightly faster, but each slot handled in the call appears to be somewhat slower. All in all, the optimizations applied have managed to keep in check the performance hits from all of the added functionality.
• Added support for FIELD attribute 'autoload' (i.e. FIELD slots that are initialized with a subroutine reference - the first access to the FIELD slot causes the subroutine to be executed). Tied interface access to these slots is not supported for the first call.
• Added support for the FIELD attribute 'wantarray'. This looks at the wantarray value to determine whether to unwrap an array reference and return it as a list.
• Added incomplete support for the METHOD attribute 'profile'. This keeps track of the number of calls to this method in a C::P::Mirror global.

0.93 Mon Jan 6 2003 (not released)

• Lots of attempted and somewhat successful optimizations
• Addition of :NO_CHECK import option that eliminates additional checks in order to improve performance
• More work remains to be done in this area - packages are expensive, and any work that can be done to optimize this would be advantageous.

0.92 Fri Jan 3 2003 (not released)

• Added support for extended slot syntax via anonymous arrays for addSlots
• Migrated trailing character support (second * for parent slots, ! on methods, & on fields) to use slot attributes. First two notations maintained for backward compatibility, but deprecated.
• Defined optimizations for extended slot syntax
• Updated tests and documentation to use extended slot syntax
• Updated getSlot to use extended slot syntax
• Added support to getSlot for format parameter
• Moved Carp::Croak lines to head of addSlots so object remains unchanged

0.91 Sun Dec 29 2002 (not released)

• Added support for constant field slots using trailing & notation
• Added tiedInterfacePackage to C::P::M
• Modified C::P::new to respect return value of tiedInterfacePackage
• tiedInterfacePackage is now read/write!
• :TIED_INTERFACE is being removed (good riddance!)
• tiedInterfacePackage is inherited when class packages are objectified
• Oodles of tests on the new tied interface support
• Tests for the new constant field slot support

0.90 Wed Dec 18 2002

• Moved addition of DESTROY symbol table entry in newPackage into code guarded by check for PREFIXED package name
• Created $parent_DESTROY search code that looks for DESTROYs that aren't clones of C::P::DESTROY
• Modified destroy and DESTROY so that parent slots aren't deleted until the destruction sequence on an object is complete
• Updated destroy.t to include parent** slots, more explicit scope ordering (which fixed test variations related to changes in the order in which lexicals exit scope), as well as use of field slots
• Added more tests to super.t
• Code passes all tests under: ActivePerl 804 (based on v5.8.0) ActivePerl 633 (based on v5.6.1) ActivePerl 517 (based on v5.005_03)
• Incremented version number to 0.90 to reflect code maturity level
