- re-enable small optimization

- factor out common code

- provide compatibility with Tcl 8.4

- simplify semantics of MixinSeekCurrent and FilterSeekCurrent, improve speed - remove necessity to have tclCompile.h - improve documentation

some small performance improvements (use CreateHashEntry instead of FindHashEntry, remove unneded argument, improve order of long and expressions)

- some code cleanup - new methods, when compiled with tcl 8.5; + MakeProcError (producing error messages from xotcl methods) + PushProcCallFrame (compile method to byte-code) The new support allows to call code at the begin of a proc without using the old approach based on :xotcl::initProcNS

- fixed reference counting - removed temporary hacks - added CONST to several functions - added relative namespace handling

  1. … 4 more files in changeset.
- added Stefan's work for namespace resolvers - fixed a memory leak for "obj exists" due to the changes - found another memory leak, when e.g. "::info" is added as an alias and "info exists" is tested against non-existing vars

  1. … 4 more files in changeset.
- Correct deletion of user-metaclasses - commenting existing and potential usage of namespace resolvers

- Correct deletion of user-metaclasses: Deletion of user-metaclasses could lead to undestroyable objects, since the instances of the user-metaclasses were reclassed to ::xotcl::Object instead of ::xotcl::Class. - extend regression test for such situations

- removed unneeded function

- new command ::xotcl::finalize to delete all xotcl objects and classes. Calls as well exit handler - some cleanup

- handle nonposargs in method "copy" properly - extend regression test for copy - added "<class> mixinof -closure ?pattern?" - extended regression test for mixinof - updated documentation

  1. … 15 more files in changeset.
- upgrading object to class and downgrading class to object not allowed via "class" method - upgrading and downgrading can be performed via create (but using destroy/create instead of recreate) - fixed bug, where an "o info precedence" could core, after a class C was destroyed, where class C was used as a superclass of a mixin of o. - minor refactoring

first part of fix when a class is "casted" (via method "class") into an object

ChangeLog

generic/xotcl.c

  1. … 1 more file in changeset.
* additional argument for "info precedence": "-intrinsic" Syntax: <objName> info precedence ?-intrinsic? ?pattern? If "-intrinsic" is specified, only the classes of the superclass type hierarchy are returnd. Otherwise, the precedence contains mixin classes as well. * Remove pattern argument from "info class" * Check results for guards to be boolean instead of integer (now, guards are allowed to return e.g. "true") * Bump version number to 1.6.1

  1. … 12 more files in changeset.
* check in guards for boolean values, not for integer values, such that a guard {true} means success

  1. … 2 more files in changeset.
* updating language reference

* Fix contents for %proc in forwarders in cases,

where the forwarder was called via next and

the argument list for next was provided.

Previously, "next" was used for %proc.

  1. … 3 more files in changeset.
* make "info (inst)?forward -definition name" more robust (provide an error message, if <name> is nog given * New info subcommands "info parametercmd" and "info instparametercmd" * export *parametercmds in Serializer, use "-noinit" on slots as well

  1. … 2 more files in changeset.
- fixed bug in info instdefault, when argument is an empty string.

  1. … 2 more files in changeset.
- xotcl.c: fix for double ;; (causes chokes MSVC6 in the next line)

  1. … 1 more file in changeset.
- Fix for "x configure -set";

updating dates in copyright

  1. … 13 more files in changeset.
- clear XOTCL_MIXIN_ORDER_VALID flag unconditionally in MixinInvalidateObjOrders() for mixins

* replaced Tcl_ObjSetVar2() with Tcl_SetVar2Ex() in nonposargs, since Tcl 8.5 seemed to optimize local variables away, if these not referenced directly from from Tcl,

  1. … 1 more file in changeset.
- new info option for "info instmixin" supporting -guards and -closure support - extended test cases for "info instmixin"

  1. … 2 more files in changeset.
* Continued with info orthogonality change

<object> info mixin ?pattern?

<class> info instmixin ?pattern?

?pattern? behaves exactly like in the change of two days

ago. Preceding colons in the name of the queried class are not

required.

Still to do "-closure" in

<class> info instmixin -closure ?pattern?

* In all mentioned calls, where pattern refers to an object/class

and it contains wild-cards, a preceding :: is added automatically

to the search pattern, if it is missing. Since all object names

start with ::, an omitted leading :: in a search pattern is an

obvious mistake

* Made the behavior "pattern" in the following calls identical

concerning wild cards and object lookups

<object> mixin delete pattern

<class> instmixin delete pattern

<class> superclass delete pattern

* extended regresson test
