<- handle change in tcl 8.5.8: http://tcl.cvs.sourceforge.net/viewvc/tcl/tcl/generic/tclObj.c?sortby=date&r1=1.139.2.1&r2=1.139.2.2&pathrev=core-8-5-branch
  in xotcl:
   * when e.g. the parent namespace is deleted with a "namespace delete", the change
     above causes, the no xotcl methods could be resolved (and called) anymore.
  * therefore, e.g. a "C dealloc c1" did not work, since dealloc passes
    c1 via tcl_obj, and the tcl_obj is as well converted to an xotcl object via
    Tcl_GetCommandFromObj(), which fails as well.
- to bypass this problem, xotcl has now a C-function DoDealloc(), which 
   is called, when this situation is detected.
- some more cases, where xotcl could reference already freed memory
   were fixed (thanks to enable-symbols=mem)
- as collateral damage, parts of the regression test don't work currently


- added refounting in ObjectDispatch() to make sure, obj survives until
   the end of the function

- added existence test for slot extractor (needed for 8.5.8)
- added refcounting CallStackDoDestroy() to ensure existance of
   object until end of function
- make sure to call PrimitiveDestroy() before DeleteCommandFromToken(),
       otherwise e.g. unset traces on this object cannot be executed
- regression test works again

- get rid of rst->deallocCalled (not needed due to reference counting 
   on xotcl objects)
- reduce verbosity

- reactivated XOTclErrInProc()

- renamed "ClassName info instmixinof ?-closure? ?pattern?" into
  "ClassName info class-mixin-of ?-closure? ?pattern?"
- renamed "ClassName info mixinof ?-closure? ?pattern?" into
  "ClassName info object-mixin-of ?-closure? ?pattern?"
- added emulation "ClassName info instmixinof|mixinof" for xotcl1 

- update to TEA 3.7 (from TEA 3.5)
- use of INT2PTR to avoid warnings about different sizes on 64bit
   architectures
- defined HAVE_INTPTR_T as a macro to make definition of INT2PTR working

- use INT2PTR and PTR2INT macros in generated stubs

- handle HAVE_UINTPTR_T like HAVE_INTPTR_T
- use ::xotcl::setinstvar instead of ::xotcl::setinstvar in serializer

- change and rename cmd instvar 
    ::xotcl::instvar -object someObject newVar
   into
     ::xotcl::importvar someObject newVar
   Rationale of change: 
      only needed in xotcl2 for importing variables
      from different objects

- changed assertions:
   old (xotcl1) interface: 3 methods + 3 info methods
      * <object> check Options
      * <object> info check
      * <object> invar Conditions
      * <object> info invar
      * <class> instinvar Conditions
      * <class> info instinvar

   new (xotcl2) interface: 1 cmd (similar to ::xotcl::relation)
      ::xotcl::assertion check|object-invar|class-invar ?arg?
- added emulation for xotcl1

- deleted namespecific C macros:
    isInfoString, isInstinvarString, isInvarString, isInstprocString, isProcString

- made some more xotcl2 methods protected 
  (no big need to call these from different objects):
  unknown, uplevel, upvar

- added ::xotcl::exists as cmd

- added ::xotcl::method as cmd instead of methods object-method and
  class-method

- added ::xotcl::forward as cmd instead of method
   now, all method-defining-methods (alias, method, forward, setter)
   are defined as cmds (this should make life of serializer easier)

- moved "-per-object" consequently immediately after obj in the
  following commands
     : ::xotcl::alias, ::xotcl::methodproperty, ::xotcl::setter
  to achiev conformance with ::xotcl::forward and ::xotcl::method
 

-per-obejct
nach methodName: 
vor methodName: alias forward method methodproperty setter


- added experimental flag for alias "-noleaf" to force a stack frame
   to be written (e.g. necessary for "next"). makes only sense for
   aliases to c-implemented cmds

- fix inconsistent behaviour of dotVarResolver
    "o eval {set .x 1}" was setting var ".x" instead of "x"
  The problem was due to a interaction between
  the namespace varResolver() and the DotVarResolver()

- fix for DotCmdResolver during compilation of a proc by Tcl.
- extended regression text
- found 2 potential bugs (not fixed yet)

- fix eval method with requirenamespace

- removed dependency on proc/instproc in copy/move.
   code is now independet of class system

- changed results of "filtersearch" and "self next" to new naming
   Caveat: for xotcl1, there is no mapping for the names to the
   old style in "self next" and "self filterreg"
- backwards compatible mapping of filterseach in xotcl1

- removed XOTclInstVar from the C-level API. 
   todo: add all xotcl*cmds to C api, including importvar

- removed all unreferenced entries from XOTE_*
- regrouped XOTE_* for easier comprehension
- used XOTE_* on more occations
- used XOTclCallCommand() for calling Tcl 
   "format" and "interp"

- added option "arg=.." to parameter options; this argument
   can be passed to converter; used currently for "type=relation"
   to flag, that the relation type is different from the parameter 
   name
- extended "objectparameter" to handle such cases
- removed relationtypes "mixin", "filter", "instfilter" and
  "instmixin" since not needed due to converterArg

- xotcl.c: removed all names starting with "inst"
   (exception: instvar)

- added option "-application" to "info callable" to 
   omit methods from base classes
- extended regression test
- changed naming of methodtype "system" to "builtin"
- added "info methods" to migration guide

- added "info method" to migration guide

- modernize test a little: all local definitions of proc "?" are gone.
- added interface to test: "Test parameter count SOMEVALUE" to 
   specify conveniently e.g. the number of tests the be executed
- add XOTCL_CM_NO_UNKNOWN to dispatch of defaultmethod

- added option "objectsystems" to ::xotcl::configure to
   obtain the currently defined object systems
- added option "baseclass" to ::xotcl::is to check, whether
   a class is a baseclass of an object system 
   (root class or root meta-class of object system)
- changed result of "... info methods -methodtype scripted"
   to return only truely scripted methods (no aliases)
- some more cleanup in regression tests
- first version of serializer for xotcl1 + xotcl2

- serializer: move checking of the requested objects 
   to be exported to the invocation of "Serializer all"
- replace "namespace import ::xotcl::*" by "xotcl::use xotcl1"

- make allocation sizes for dynamically allocated parameterContexts
   consistent between alloc and realloc
- added sanity check in getAllClassMixinsOf()
   It seems as it would be possible with __defaultSupeclass to define
   a class which has itself als a subclass. Just a quick
   fix, we have investigate more on this.

- improved naming of resolvers: use InterpDot*Resolver and
  NsDot*Resolver for interp wide and namespace specific resolvers
- added possibility to escape the call of commands starting
   with a dot from method bodies by prefixing with a second dot.
 
- make sure to have an xotcl frame pushed, when byte-code-compiler
   is invoked. This is necessary for providing the context for 
   dotCmd resolvers

- use uplevel in slot add/delete to evalute in calling namespace
   (for not fully qualified object names)
- determine namespace in test method "?" to allow its execution
   in an "namespace eval"
- added regression tests


- NsDotVarResolver: don't create variables on CMETHOD frames
   when their names do not start with a "."

- general overhaul of XOTcl_PushFrame()XOTcl_PopFrame():
   new functions: 
     * XOTcl_PushFrameCsc()/XOTcl_PopFrameCsc(): for CMETHOD fames
     * XOTcl_PushFrameObj()/XOTcl_PopFrameObj(): for OBJECT frames
       (objscope)

- preallocate obj->vartable in XOTcl_PushFrameObj() to 
   avoid situations where to non-existing vartable is created
   on demand at different places (e.g. on stack and in 
   var resolver)

- caller of convertToRelationtype(): make sure that last argument
   keeping the result is large enough to held pointer (in case of
   sizeof(void) != sizeof(int)

- Serializer: include ObjectSystemSerializer in "Serializer all"
- Serializer: use class-mixin in dependency order
- Serializer: add appropriate "::xotcl::use xotcl1|xotcl2"
- Serializer: fix syntax in exportMethods
- Serializer: provide limited support for exporting aliases for xotcl1 objects

- add calltype to tcl85showStack

- keep orignial objc/objc in call stack context such that
   next/self args works with canonical args (allow e.g. 
   different order of nonpos args in a next)
- make naming in xotcl.c more consistent
- ensure to return empty, when "info callable -which" fails
- extend regression test

- exithandler is different in xotcl2 -> comment, check openacs
- ensure relation filter/instfilter etc. mit guards

- extended migration guide
- defined eval in predefined via "-nonleaf", used at various places
- added "info mixinof ?-scope all|object|class? ?pattern?", dropped
   "object-mixin-of" and "class-mixin-on" from registerd method
- extended regression test 
- xotcl1: make "-volatile" invoked via unknown behave correctly

- provide minimal xotcl2 compatibility
- added non positional parameter "type" to "get_parameter"
- removed "required" from parameters, which is in XOTcl 1 just a comment
- minor cleanup

- experimental change of resolver name prefix char from dot to single colon

- making methodDefinitions NULL terminated
- passing optional arg to user-defined argument converter
- refuse to redefine type converters for a single parameter
- adding regression test for parameters

    - added instance variable arg for interfacing with parameter
      interface. "arg" acts like a clientdata for type converter
    - added multiple parameter options handling to method "parameter"
       to obtain similar functionality from object parameters
       as from method parameters
    - added conveniance method "??" to test to indicated test
      that should fail with an error
    - added severy type converters to achieve same
       object type checking as in ::xotcl::is
       (these are currently in the regression test, should move
       finally into predefined.xotcl)
    - extended regression test

- new function ::xotcl::parameterFromSlot (used in argument checker as  well)
- use ::xotcl::forward in Slot constructor (instead of dispatch)
- checking methods on slots for single- and multivalues slots
   (can be optimized)
- extended regression test

- don't run multiple queries in "??"
- fixed last changes to regression test as usual

- added "multivalued" to parameter options
- made error message produced by XOTclObjErrType look like Tcl's error
   messages
- extended regression test
- test utility: changed "?" to return error msg in case of error

- checking multivalued types in "-parameters" by using argument
  checker
- some cleanup
- extend regression test

valuecheck.001:	  5.27 mms, ::xotcl::valuecheck object o1
valuecheck.002: ::xotcl::valuecheck object 1 ok
valuecheck.003:	  3.06 mms, ::xotcl::is o1 object

- new cmd "::xotcl::valuecheck <valueConstraints> <value>"
  where "valueConstraints" is whatever is allowed in e.g. parameters 
  (including user defined types)
- new Tcl_ObjType "xotclParam"

- parameterFromSlot returns now pair object-param & method-param
- define dissallowed parameter options for object parameter, method
  parameter and valuecheck command
- make canonical table of parameter options (currently in
  tests/parameter.xotcl)
- extend regression test
- systematic checking, what valueconstraints should be allowed/not
   allowed in valuecheck

- pass arg from objectparameter as first argument to objparms
   (similiar to client data)

- support for parameter spec of form "type=XXX" to denote that
   the parameter must be an object of the specified type (class;
   directly or indirectly)
- new built-in converter: convertToObjectOfType()
- keep parameterObj (source for conversion to XOTclParam) 
   for making introspection less work. However, this is 
   only used for XOTclParams generated via ParamParse().
- extending regression test

- name XOTclObjects always "object" instead of "obj" to avoid 
   potential confusion with Tcl_Objs

- remove unneeded push and pop operations in ListChildren() and
   ObjectHasChildren() 

- allow syntax "object,type=::SomeClass" and "class,type=::SomeMetaClass"
   (currently identical, we should as well check for class/meta-class
   in case of "class,type=SomeClass")

- define everything concerning basic slot setup in a single 
   "namespace eval ::xotcl {...}"
- undefine ::xotcl::createBootstrapAttributeSlots after this block
- fix default DefaultSuperClass() with isMeta==1 in cases, 
   where we are already at the root meta class
- use "-parameter" in xotcl1 instead of  createBootstrapAttributeSlots

- cleanup of legacy stuff in slot management.
   * merged InfoSlot and InterceptorSlot into RelationSlot
   * get rid of legacy "mixin set ...." command
- renamed "parameterSlot" into "methodParameterSlot" to avoid 
   potential confusions

- refactor Slot class hierarchie
- new methods in ObjectParameterSlot "toParameterSyntax" and
  "createFromParameterSyntax"
- some more cleanup
- removed legacy syntax for "-parmeters"

- moved slot optimizer from ::xotcl::ObjectParameterSlot::Optimizer to
  ::xotcl::Attribute::Optimizer

- support for all string constraints provided by "string is ... $value"
  in object and method parameters ("alum", "alpha", ..., "xdigit"). 
  Technically, these types are tclobjs (using converter convertToTclobj)
  having pParm->converterArg set to the constraints.
- extended regression test

- get rid of convertToObjectOfType(), make convertToClass() and 
  converterToObject() more general, accepting type constraints

- predefined.xotcl: move toParameterSyntax and objectparameter to 
  a position, where basic slot definitions are provided
- fixed default value setting in bootstrap code
- provide more precise error message in converter,
  when object type are used
- extend regression test 

- added error message when substdefault is specified without a default value
- extend regression test 

- added parameter option slot= to pass slotobj to a certain parameter
- use slot option to keep relation between parameter and slot
- object parameter dispatch type checker on slot objects
- allow transformation via user-defined converter (can be use to 
  standardize parameter values)
  experimental implementation, refcounting has to be looked
  in detail, maybe we need a different interface for the converters

- provide checker-methods for
   -> objectParameter
   -> methodParameter
- slotobject specific checker-methods

- treat currently unknown converters in valuecheckcmd as error
- fix the regression test from the last changes

- added argument for converter to return the converted tcl_obj, which
  should be passed on (currently only used for viaCmd); this way,
  we could remove the kludge of querying the converter after the conversion
  for special handling.

- handle multivalued + values converted viaCmd converter the new
  output list is only built when needed via ArgumentCheckHelper()

- fix counter initialization in ::xotcl::importvar
- register alternate "new" method in "contains" for xotcl2 and
  (if available) for xotcl1 objects

- provide error message for cases, where parameter options are not
  allowed (or ignored)

- move methodParameter checkers for "mixin", "baseclass" and "metaclass"
  to predefined.
- deactivated checkMethods in gentclAPI.decls and in xotcl.c

- renamed "::xotcl::is ... mixin ..." to "::xotcl::is ... hasmixin ..."
  (effects parametertypes as well)

- made error messages for failed conversions more consistent
  (note that tcl does not provide the parameter name in the error message,
  but user-defined converters do)

- fixed valuecheck in connection with modifying converters
- extended regression test

- fixed compilation for tcl 8.6b1

- Allowed parameter specification for setters.
  One can define now a setter with constraints like e.g.
     ::xotcl::setter o a:integer
  to define a setter named "a" for object "o" which
  has to be integer.
- Extended regression test
- Followed naming conventions for several structures

- setterCmd(): Do not allow methodNames start with "-"
- setterCmd(): Do not allow defaults for setters
- extend regression test

- removed duplciate error message in "hasmixin" converter
- fixed refcounting in converting user-types in case of errors
- extended regression test

- added a "-nocomplain" option to ::xotcl::valuecheck
- changed semantic of ::xotcl::valuecheck: per default,
  valuecheck raises an error or returns true. 
  If "-nocomplain" is used, valuecheck returns
  0 or 1 like implemented befor this change
- extended regression test

- added parameter "incremental" to ::xotcl::Attribute:
  when set, one can use "object paramname add|delete $value" etc.
- use setters with parameter constraints in slot optimizer
- as a consequence, setting attributes via slot names is about
  twice as fast as before, when parameter constraints are used.
- extended regression test

- fixed returned method name when setter was used on objects
- reduce verbosity

- implemented "info method definition|parameter|args $name" for 
  settercmds (with parameter constraints)
- extended regression test

- fixed result resetting for user defined converters

- ::xotcl::valuecheck: moved "-nocomplain" to first position
  (similar to e.g. unset)

- experimental: allow to shadow built-in types provided that
  a) slot= is specified explicitely, and
  b) the specified slot is not the default slot.
  This should guarantee that we do not interfere with 
  the predefined converters for the c-level interface.
- incremented ref count on results of all-level converter
- extended regression test

- new methods for MetaSlot to factor out common code:
   + slotName (to ease name-construction, care about 
     slot container)
   + createFromParameterSyntax: essentially move from 
     ::xotcl::Attribute to the meta class
- test environment: make sure to avoid confusions between
  the "namespace" method and command

- added a version of the "attribute" method to predefined

- removed the following classes and methods
     ::xotcl::Attribute->check_single_value
     ::xotcl::Attribute->check_multiple_values 
     ::xotcl::Attribute->mk_type_checker
     class ::xotcl::Attribute::Nocheck

- centralize fetching of tcl-obj-types in xotcl_init

- support for method modifier "object", "protected" and "public"
  for method "attribute". One can use now e.g.
  
     Class create C {
       :attribute a
       :public attribute b
       :protected attribute c

       :object attribute A
       :public object attribute B
       :protected object attribute C
    }

  "protected" and "public" refers to the registered accessor functions

- experimental checking function ::xotcl::is2 implemented, which generalizes
  between ::xotcl::is and ::xotcl::valuecheck (it is a valuecheck -nocomplain 
  with an ::xotcl::is syntax and switched arguments)

- Unified on c-level "info class-mixin-of" and "info object-mixin-of"
  to "info mixinof ?-scope all|object|class? ?-closure? ?pattern?
  The former "info class-mixin-of" 
  is now "info mixinof -scope class"
- adapted xotcl1 layer for this change
- extended experimental ::xotcl::is2 to handle flags -type and -hasmixin
    ::xotcl::is2 <obj> object ?-type <type>? ?-hasmixin <class>?

- renamed old "xotcl::is" -> "xotcl::objectproperty"
- renamed old "xotcl::is2" -> "xotcl::is"
- we have now is tests for objects in ::xotcl::objectproperty
    ::xotcl::objectproperty $obj object
    ::xotcl::objectproperty $obj class
    ::xotcl::objectproperty $obj baseclass
    ::xotcl::objectproperty $obj metaclass
    ::xotcl::objectproperty $obj type XXXX
    ::xotcl::objectproperty $obj hasmixin XXXX

- "::xotcl::is" is the higher level command, 
  supporting string contstraints "e.g. upper", user defined type checkers
  and as well object properties (every parameter type supported for object
  and method paameter). Examples:
    ::xotcl::is $obj object ?-type $type? ?-hasmixin $mixin?
    ::xotcl::is $cl class ?-type $type? ?-hasmixin $mixin?
    ::xotcl::is obj metaclass
    ::xotcl::is $num integer
    ::xotcl::is $string upper

- implemented 2nd level reference counting for paramObjType

- defined "info is" as alias of "::xotcl::objectproperty"

- renamed ::xotcl::valuecheck -> ::xotcl::parametercheck
- replaced in predefined occurances of ::xotcl::is by ::xotcl::objectproperty

- fixed namespace handling on stack for objects with namespaces
  (before, it was possible that a variable was created in 
  an object's namespace without -objscope)
- as a consequence, ListChildren() had to be adjused, since
  it depended on the previous namespace handling on the stack
- fixed object sesolving in NsDotVarResolver()
  (before, it was possible that NsDotVarResolver could
  create variables in the wrong namespace)
- simplified NsDotVarResolver()
- more cleanup in name resolver
    * USE_DOT is gone
    * XOTclDotDotCmd() removed
    * improved performance of InterpCompiledDotVarResolver()
    * made LookupVarFromTable() obsolete and removed it 
    * renamed DotVarResolver() and friends to ColonVarResolver() etc.
- extended regression test

- call XOTclObject always "object" instead of "obj"

- initcmd: use for initcmds CMETHOD frames instead of OBJECT stack frames
- initcmd: skip parent-stack frame's objscope for initcmd
- changed hash-based lookup of children into a cmd-based lookup
- extended regression test

- cleanup in stack handlers (naming, arguments)

- XOTclCallStackFindLastInvocation(): return last scripted invocation
- use xotcl1 in webserver test to make rull regression test working
- make xotcl::use silent

- added option "-nonleaf" for method alias 
- added introspection (for "info method definition") for "alias ... -nonleaf ..."

- removed obsolete ::xotcl::configure option "cacheinterface"

- removed XOTclCreateClass() and XOTclDeleteClass();
  both are identical with XOTclCreateObject() and XOTclDeleteObject()

- renaming of instance variable specific primitiva for more
  constistency with ::xotcl::importvar:

    ::xotcl::exists -> ::xotcl::existsvar
    ::xotcl::setinstvar -> ::xotcl::setvar

- requireNameSpace: 
   * fix potental crash in requireNameSpace in objscoped methods
     by swapping all vartable references in objscopes on stack
     to the vartable in the namespace, when it is created
- extending regression test   

- working towards KEEP_VARS_IN_CMETHOD_FRAME

- enable compilation with assertion turned on (via NDEBUG)
- fix potentially uninitialized flags for ArgumentCheck()
- some further cleanup, tested with 32 bit under Mac OS X 10.6

- removed obsolete generic/xotclAppInit.c
- changed loading method in xotclsh from Xotcl_Init() to Tcl_PkgRequire()

- updating tcl.m4 to the actual verison (TEA 3.7)
- minor cleanup (varresolution test and comment)

- defined "xotcl::current" as synonym for "::xotcl::self"
- new options for ::xotcl::current
   current object == current
   current method == current proc
   current callingmethod == current callingproc
- "self proc" and friends are for backward compatibility for xotcl1, 
  "current method" and friends are for xotcl2
- namespace exported "::xotcl::current"

- use "::xotcl::current" instead of "xotcl::self" in predefined 

- use "CONST char *" in generated interface and below
- further cleanup using "CONST char *"

- remove dependency from xotcl1 in handling of forwarders in method "copy"
- further cleanup using "CONST char *", improving on naming conventions

- added an experimental "info frame" handler, which appends "object" and
  "class" pairs

- fixed wrong name for per-object filter in RelationSlot
- fixed condition in filter-incovation to top-level frames
- added frametype to information returned by "info frame"
- change frametype in "info frame" form bitpattern to symbolic names
- use a more recent version of unix/tclAppInit.c
- fix syntax in predefined
- let serializer call "init" of attributes, even if it is protected

- fixing "-parameter" with empty content
- more variable naming cleanup
- fix line breaking in serializer for "exportedObjects"

- call c-implemented methods directly, when this is safe
  (implemented for XOTE_ALLOC, XOTE_CLEANUP, XOTE_CONFIGURE, 
  XOTE_CREATE, XOTE_DEALLOC); this improves create/destroy
  speed by up to 15%
- allocate namespaces for objects less eager
- make nameing more consistent 
  (change newObj into newObject when variable is an xotcl object)

- get rid of misleading RCS: lines
- passing --prefix to subdirs
- regenerated configure files

- added stefan's expat library linking extension

- define RecreateObject() for internal call via direct invocation
- doCleanup is just called by recreate; merge it into 
  XOTclCRecreateMethod. 
  Is method cleanup necessary? is recreate not sufficient? 
  Delete "cleanup" from internally called methods in next, 
  keep it for compatibility in XOTcl

- make XOTcl_FrameDecls transparent (use variable declarations 
  in place instead of the macro)
- fix variable shadowing bug in error handling 
  (could cause crashes when initcmd lead to errors)

- call all truely essential methods directly if possible
  (Object.destroy, Class.alloc, Class.dealloc, Class.create)
  The basics of XOTcl can work now also in cases, 
  when these are not defined as methods.

- handling OBJECT-frames in CallStackPopAll() 
  (for handling exit with active stack frames)

- deactivate filters in finialize
- new method InvokeMethodObj() to replace finally CanInvokeDirectly()

- remove some more obsolete RCS Ids
- call Tcl_Objs "Obj", not "Object"

- replace all CanInvokeDirectly() by InvokeMethodObj()

- block call-stack deletes during XOTCL_EXITHANDLER_ON_SOFT_DESTROY;
  however, this seems to create a small leak during exit 
  (revant for threads); so currently, debug still turned on

- fix last issue, with freeing objects, when exit happens from
  higher stack frames

- first part of allowing arbitrary named internally called methods.
- move refcount fixing logic for exit from higher stackframes to new function: finalObjectDeletion()

- created new functions:
     ObjectSystemFree(), ObjectSystemAdd(), ObjectSystemsCheckSystemMethod(),
     ObjectSystemsCleanup(), GetObjectSystem(), CallDirectly()
  for better separation of systems. We keep track which essential system
  methods are defined and which which methods are potentially overloaded.
  
- replaced hard-coded method calls for XOTE_DEFAULTMETHOD, XOTE_INIT,
  XOTE_OBJECTPARAMETER with MethodObj()

- renamed MethodObj() to XOTclMethodObj() (it is an exported symbol)
- eliminated XOTE_MOVE
- eliminated XOTE_RESIDUALARGS
- eliminated XOTE_UNKNOWN
- eliminated XOTE___UNKNOWN
- renamed __unknown to requireobject

- provide prefix for internally called methods to distinguish between 
  methods called on objects or classes

- handling of minimal object systems. For example, the
  following three command create an object system around
  ::object and ::class ...

   ::xotcl::createobjectsystem ::object ::class
   ::xotcl::alias ::class  + ::xotcl::cmd::Class::create
   ::xotcl::alias ::object - ::xotcl::cmd::Object::destroy

  ... where no internal message dispatch are used (e.g. no
  constructor "init", and where just two methods ("+" and "-")
  are used to create and destroy objects
- extended regression test

- get rid of reminder of tcl 8.4 compatiblity and remove range of
  ifdefs, such as PRE85, FORWARD_COMPATIBLE, TCL85STACK, 
  CANONICAL_ARGS, USE_COMPILED_VAR_RESOLVER

- rename CallStackPush() to CscInit()
- rename CallStackPop() to CscFinish()

- remove "buffer" from compiled var structures
- remove xotcl1 dependency from aol-tcl
- removed conditional var table creation by assertion
- make clean compile with assertions turned on

- xotcl 1.6.6: make sure to load always xotcl 1 versions when needed
- xotcl 1.6.6: make compilation clean when compiled with assertions on
- xotcl 1.6.6: more cases for the regression test, where we want to load xotcl1 not 2
- xotcl 1.6.6: one more cases for the packaging, where we want to load xotcl1 not 2

- replace hash-lookup in namespace in ObjectHasChildren() by pointer lookup 
  to reduce namespace dependency.
- fix memcopy size

- add check for optional match arguments in tcl stub generator
- fix potential memory leaks
  all "definitely losts" from valgrind (except 24 bytes from Tcl_PkgRequire) gone

- fix a potential ordering problem with cyclic dependencies created by
  namespace import commands

- Handle cases, where objects/classes are created with the name
  of preexiting namespaces. Cases, where pre-exisitng namespaces
  contained classes/objects lead to problems, since xotcl did not
  see the object/classes of the pre-exiting namespace as children
  of the new object/class.

- Allow to speficy last arg of objectparameter to replace scripted init
  block. The redefinition of objectparameter allows us to specify whether
  no/some/classical/altered/additional arguments should be allowed during
  object creation


- Naming

     namespaces: 
       ::next
       ::next-core

     file exension:
       options:
          .tcl
          .xotcl
          .next
          .nxt

    file names:
       composite words with - instead of capitalization

    package names
      next::pkgname
      next::doc-tools   # use - instead of _ or capitalization

    Classes
      use first name capitalized to distinguish from objects

    Objects
      typically, first charaction small

- next::core as namespace name not perfect for adressing variables:
  set ::xotcl::version ${::next-core::version}
  set ::xotcl::patchlevel ${::next-core::patchlevel}

do we need:
  checkMethod  "::next::core::cmd::ParameterType"

- namespace changes:
  mostly due to marketing reasons, the naming of the top-level namespace 
  changed from "xotcl2" to "next".
  reasons: xotcl is hard to pronounce for beginners, sounds like "exotic" 
  (but who wants to program in an exotic language) has a certain stigma
  of strange namings (e.g. "instproc"), is seen as a precursor of tcloo,
  the top-level namespace ::xotcl2:: is not very nice either, the separation
  of framework and language is not clear.
  
  We have now: 
    ::next (the new object system, former ::xotcl2)
    ::next::core (framework, primitives)
    ::xotcl (former xotcl1)

- "::xotcl::use" no longer needed, use Tcl standard mechanisms instead
  (e.g. "package req next"; "package req XOTcl", "namespace import ::next*")

- [self next] returns 
      instead of "proc" and "instproc" => "method"
      instead of "parametercmd" and "instparametercmd" => "setter"
      instead of "instforward" => "forward"
      instead of "instcmd" => "cmd"
   prefixed with the modifier "object" when needed
- [self filterreg] returns
      instead of "instforward" => "forward"
   prefixed with the modifier "object" when needed

-  We have now: 
    ::nx (the new object system, former ::xotcl2)
    ::nx::core (framework, primitives)
    ::xotcl (former xotcl1)

- naming next scripting framework
   ::nx::core::existsvar  <==> nx::var exists
   ::nx::core::importvar  <==> nx::var import
   ::nx::core::setvar     <==> nx::var set

- copied infoObjectMethod and infoClassMethod decls as comments
  to xotcl.c, aligned order of method definitions

- removed "[o exists varname]" from next scripting language
- reanimated "info vars" to show locals in eval method
- provide error messages for [objectproperty ... type ...]
- replace 0 by NULL in calls to GetClassFromObj()
- extended regression test

- use size_t where appropriate
- added notnull annotations

- Implemented "Class info parameter" in Tcl, aliases for xotcl.
  Now both definition of parameters and setting of __parameter are
  in Tcl.

- get rid of ":::xotcl::use"
- renamed tests based on next from .xotcl to .tcl

- renamed predefined.xotcl -> predefined.tcl
- additional subcommand "info method parametersyntax <methodname>"
  returns parameters in a syntax similar to the tcl man pages
- added ability to pass syntax for forwarded methods 
  via set ::nx::core::signature(::nx::Object-method-forward) 
  (experimental)
- fixed documentation system to work with actual version 
- added undocumented methods for quality control in documentation
- added checks for documented, but unavailable methods in documentation
- added comparison of documented parameters vs. actual parameters in documentation

- added @properties and has_property to the documentation classes.
  Current primary purpose: define, which methods are internally-called 
- added internally-called to the method object template

- added redefine-protected to the object template
- added methodtype to object template
- some documentation updates
- some indentation/spacing improvements on xotcl.c
- let ".... info method .... METHOD" return values,
  when METHOD contains namespace prefix. This can be 
  used to obtain the parmeter definitions from nx::core

- created own directory structure xotcl under library
  containing doc, tests, apps, lib etc. and moved
  obvious content here.

- moved some more xotcl specfic tests to library/xotcl
- transformed forwardtest from xotcl to next

- moved slottest to library/xotcl
- added new Makefile target test-xotcl
- finished test migration for now
- deactivated __next for now

- iterated through doc.tcl-TODOs
- changed CheckVarName to allow array names like e.g. a(::b)
- extended regression test
- fixed serializer to handle subobjects of explicitely exported objects

- xotcl.c: 
  * new function GetObjectFromNsName() to obtail object or class
    from a fully qualified namespace name used in method handles (such as e.g.
    ::nx::core::classes::X)
  * new function MethodHandleObj() to return a tcl_obj containing the methodhandle
  * removed obsolete method getFullProcQualifier()
  * info methods obtain now object and/or class from fully qualified method 
    names (method handles) if possible
  * return message handles in "current next", "current filterreg" and
    "... info filter ... -order", which can be used in "info method .... "
    for obtaining more details.
  * change all occurrances of "self" in next regression tests to current.
- xotcl2.tcl
  * implemented "self" as a proc to provide extensibility and 
    full backward compatibilty; this opens opportunity 
    to replace now e.g. "self proc" by "current method", etc.
  * provide full compatibility for "self next", "self filterreg" and 
    "... info filter ... -order", returning old-style multiword method handles
    (such as e.g. "::C instproc foo")
- changed "next" to current in documentation framework and templates

- updated migration guide, added section for callstack introspection
- updated serializer for new names

- Introduced $xotcl_target_doc_dir for generated xotcl documentation.
  Generate xotcl documentation in this directory.
- moved more (hopefully all) xotcl doc components into library/xotcl/doc
  
- added interp alias "nx::self" to "nx::core::current method"
- changed "current proc" into "current method" in scripts and tests

- file extension for next scripting .tcl DONE
- changed ::nx::core to ::nsf

- made the "next scripting laguage" a own, loadable tcl package
  (currently named nx, name is subject of change)
- predefined.tcl is now pretty minimal.

- updated to TEA 3.8
- moved all exports of nsf to predefined.tcl
- made imports in xotcl2 and nx explicit

- adjusted path in documentation system for nx/nx.tcl

- Implemented "interp alias" support for classes.
  In some cases. interp-aliased classes worked already
  without additional code, but e.g. in "... -superclass C ..." 
  it failed. Without this feature, one could not reuse a
  class with a different namespace, unless it was explicitely
  "namespace exported" in the source. The problem was the 
  implementation of "::nx::Attribute", which should not be
  exported in nx (most people do a "namespace import ::nx::*")
  because there is no need to do so, but ::xotcl::Attribute 
  should reuse it - without subclassing). .... However,
  we still seem to have a problem, when the interp-aliased
  Class is exported and imported to a different namespace.

- TODO: info methods shows finally "slots" and "slot". Wanted? Actually no.
- removed definition of slots from nx, changed regression tests
  examples to to ::attribute instead of -slots 
  
- replaced several occurrences of "eval" in nx.tcl and xotcl2.tcl

- implemented parameter option "allowempty"
- extended regression test

- commented out XOTCL_CMD_NOT_FOUND, since it seems to be obsolete by now
- extended regression test to avoid CallDirectly on dealloc (the last place, 
  where XOTCL_CMD_NOT_FOUND was used)

- implemented return value checker (for scripted and c-implemented methods)
- additional methodproperty returns (for registering a return value checker)
- support for incrementally adding stuff to paramDefs (such as slotobj or return value)
- new c-function ParamDefsNew()
- added regression test for return value checker

- upgraded to TEA 3.9
- nsf: provided scripted support for "require/provide methods"
- nx: new method ":require namespace" ":require method" "require object method"
- added regression test method-require
- removed requireNamespace from nx.tcl (still exists in xotcl)
- replaced "requireNamespace" by "require namespace" in nx regression tests 
- updated migration guide

- removed method "autoname" from nx.tcl
- added "method require autoname"
- added "method require exists"

- removed method "filtersearch" from nx.tcl
- added "obj info method filter methodName" to nx
- updated xotcl2 to use new filtersearch imprementation
- updated migration guide


- renamed "info method name ..." into "info method handle ...", 
  since it returned already the handle
- renamed ListMethodName() to ListMethodHandle()
- changed output of "info callable -which ..." from definition to method handle
- renamed "info callable -which ..." into "info callable method ..."
- updated regression test to reflect the changes

- changed "info method filter ...." into "info callable filter ..."
- fixed "o info callable method" in some cases with mixins
- extended regression test
- updated migration guide

- made Class.info, Class.mixin, Class.filter robust against per-object 
  mixins from meta-classes
- extended regression test

- checked saftey of Class.method, Class.alias, Class.setter, Class.forward 
- made Class.filterguard, Class.mixinguard, Class.attribute 
  robust against per-object mixins from meta-classes
- fixed mixin/filter delete methods with guarded operations
- extended regression test
- all methods defined on both, Object and Class are now safe in respect
  to per-object mixins with meta-classes

- make slot optimizer more robust
- removed methods object-mixin and object-filter from the interface.
  (Caused some duplication of logic in the method "object")
_ added option noforwarder to RelationSlots
- some minor cleanup

- removed XOTCL_METHODTYPE_OBJECT from XOTCL_METHODTYPE_BUILTIN
- default methodtype returns now everything, which is a true method
  (except objects)
- methodtype -all includes objects
- the object "slot" does not appear now in the method listing per default
  for classes having slots

- changed __invalidateobjectparameter from a method of class
  to framework primitiv ::nsf::invalidateobjectparameter

- experimental method-property "class-only": this allows to
  make object save against per-object mixins of meta-classes.
  the flag is only used in the mixin-resolver
- used for the time being in nx only for Class.info, 
  but would apply as well for methods defined on both Object and Class.

- use now class-only for all methods methods of meta-classes. 
  Methods of meta-classes are intended to be applied on classes,
  one should not change this via per-object mixins.
- respect class-only in "info callable methods|method"
- extended regression test
- provided relation name "object-filter" to slot filter.

- replaced "obj|cls filterguard name cond" by "obj|cls filter guard name cond"
- replaced "obj|cls info filterguard name" by "obj|cls info filter -guard name"
- replaced "cls object info filterguard name" by "cls object info filter -guard name"

- replaced "obj|cls info mixinguard name" by "obj|cls info mixin -guard name"
- replaced "cls object info mixinguard name" by "cls object info mixin -guard name"
- removed XOTclObjInfoMixinguardMethod() 
- removed XOTclClassInfoMixinguardMethod() 
- extended regression test
- updated migration guide

- deactivated "abstract"

- implemented experimental delegating version of "object as method"
  that keeps the original self.

- changed requireNamespace to "require namespace" in lib/make.tcl
- use prefix sub= for methods invoked on "object as method"
- change further instances of "my connection" to "[self]::connection" in xo*comm*

- implemented "object-methods-only" as alternative for prefix for 
  invoke "object as a method"
- added option "-returns" to Object.method

- added option "-returns" to Class.method
- added subcmd to method/object method in nx
- delete class methods in freeAllXOTclObjectsAndClasses() explicitly
  to handle potential double-deletes
- extended regression test for subcmds

- started new interface bundles, objectInfoMethod and classInfoMethod
  for using new infrastructure
- added object info methods filterguard, filtermethods, vars to objectInfoMethod
- added class info methods filterguard, filtermethods to classInfoMethod
- built a temporary solution for dispatcher "filter", since forward mangles args
- nx: we have now "obj info filter guard name" instead of "obj info filter -guard name"
- nx: we have now "obj info filter methods ...." instead of "obj info filter ...."

- added object info methods mixinguard, mixinclasses to objectInfoMethod
- added class info methods mixinguard, mixinclasses to classInfoMethod
- built a temporary solution for dispatcher "mixin", since forward mangles args
- nx: we have now "obj info mixin guard name" instead of "obj info filter -guard name"
- nx: we have now "obj info mixin classes ...." instead of "obj info filter ...."
- updated migration guide

- changed info to new interface (partly done for nx, migration for xotcl to be done)
- fixed "info methods" and added "-methodtype all" for setting class-only
- regression test works now until first XOTcl reference

- Changed handling of "child objects": now, they are shown by default.
- At the same time, the subobject "slot" was made protected to avoid
  its listing per default in "info methods"
- unified slot parent-object creation handling
- changed XOTcl info to new interface

TODO: 
- check "my" vs. "nsf::dispatch" in xotcl2.tcl
- overthink decision about not showing "child objects" per default in "info methods"
- continue migration nx in regression test

- deeper analysis of "contains"
- unify SubcmdObj() and ParamCheckObj() handling?
- are "info class*" ops needed?

- subcmd
   * handle sucmd for other method factories
   * handle introspection for subcmd nicely
   * handle absence of -create  flag in resolve_method_path (for introspection)
   * consider alternate method name/place for subcmds on classes
   * provide new tests for "TODO: changed xxxx"
   * testx.xotcl
        # TODO REANIMATE xxxx
	#::errorCheck $::r "loggingFilter-open open x" {info guarded scope}
        # (inst)mixinguard, (inst)filterguard
- aliases on procs are a problem, when upvar is used (see info default/instdefault in xotcl2.tcl)

- add incompatiblity to migration guide
  Foo slot ints eval { set :incremental 1; :optimize}
  should become:
  Foo::slot::ints eval { set :incremental 1; :optimize}


- interfaces in documentation for slots (see for more details 
  ::nx::Class#superclass in nx.tcl).
- nameing
    * self/current:
       - overthink general replacement of "self" by "current".
         a consequence is, that slots can't use "self" anymore, since slots
         are always next objects
       - replace  "self proc" by "current method", etc.
       - we have "%self" as well, which is better than "%current"
       - maybe provide alias "self" for "current object" - DONE for now

    * .c-code:
      . rename source files from xotcl{Int}.{ch}->next*.* | next-scripting*.* ?
        Stefan, meinung dazu? Notwending|Empfehlenswert|nicht? 
        bei den TEA definitionen stand was von max. 8zeichen für source code namen.
        andere optionen?
      . prefix for exported symbols (XOTcl_ -> Nx_ ?)
      . prefix for symbols (XOTcl->Nx ?)
      . prefix for symbols (XO->NX ?)
      . library nameing libnext* or libnx*

    * namespace prefix 
       next scripting language: ::nx::*
       next scripting framework: ::nsf::*
    * distributed packages in namespace ::nx::*
    * names of subpackages nx::*

    * Now we have
        package require nx
        package require nx::test
        namespace import ::nx::*

    * parameter option allowempty is a little longish; we should
      choose probably a shorter name

      Object create o {
        :method foo {x:integer,allowempty y:integer os:object,multivalued,allowempty} {
          return $x
        }
      }

- documentation
   - documentationssytem
   - langref (xotcl 2.0 + next-scripting)
   - tutorial (split)
   - migration guide

- library + apps
    - new directory structure DONE
    - work on binary packages of xotcl (store + xml)
    - nicht gewartete/nicht getestete library aus distro entfernen?
    - migration von einzelnen paketen nach next? von welchen?

- new website
    * graphisches design
    * website-struktur
    * org. tutorial (bzw teile davon) ala book 
      or wiki (features als kategorien|tags|sections|directories)

Ein paar Punkte im folgenden könnten obsolet sein:

TODO "Kleinigkeiten"

- integrate ::nx::doc::make with Makefile.in
  (provide shell calls and, targets and dependencies)
- decide on syntax in documentation
  (info method parameter | info method parametersyntax | mixture, e.g. parmetersyntax with value-checkers)
- decide on paths for documentation of next and xotcl 2, with
  version numbers; what should be included in distro, what on web-site
- decide on syntax subcomponent. Candiates are
   * Object.method
   * Object->method
   * Object#method

- handling namespaces in documentation 
     # @object ::nx::Slot
  vs. 
     # @object Slot
  (best allow both variants, write fully qualified name via introspection)
- why only @object? there seems to be no @class. what to do with metaclasses?

- systematic way of specifying results of methods
- systematic way of reporting results in documentation
- reduce indenting for code examples in documentation (high indentation makes readability worse).
  i use usually jsut 2, 4 are ok as well; we should decide.
- make quality checks (missing documentation, ...) optional (maybe?)
- handle object methods as well in quality checks
- why does one have to specify @superclass rather than determining the
  superclass via introspection?
- handle line-breaking in long @definitions (e.g. @param; e.g. via indented next line)
- danger, tcl-commands in comments (see :method get_unqualified_name)
  expecially for code commented out.... 

- kann man "[:? {[$attr eval {info exists :default}]}" durch "[:?var :@param ..." ausdrücken?
  oder vielleicht besser die variablen mit leerstring initialisieren + infrastrukt anpassen?
- listing von methoden im left-bar, ähnlich http://developer.yahoo.com/yui/docs/YAHOO.util.Connect.html
- "Objects" im left-bar irreführend, sollten eher "Classes" sein. Allerdings sollten
  auch objekte dukumentierbar sein

- doc-tools: was machen die argumente von :? (bspw. ops?); ich nehme an, das ist work in progress.
  sinnvoll wäre: [:?var obj varname body], da viele (die meisten) operationen 
  auf anderen objeken ausgeführt werden

- die Dokumentation der Objekt- und Klassenmethoden muss aus gentclapi weg
  und in predefined.tcl und xotcl2.tcl hineinwandern. Es werden nicht alle
  möglichen methoden in next und/oder xotcl2 registiert, ein paar namen sind
  anders, etc.

- die folgenden calls sind streng genommen auch internally-called (d.h. von c aus aufgerufen), 
  aber aus unterscheidl. gründen noch nicht als solche gekennzeichnet:

  * wird meist vom benutzer aufgerufen, allerdings auch intern (bspw "reate" von "new")
    XO_c_create_idx, 
    XO_o_destroy_idx, 
    XO_o_move_idx, 

  * not documented yet
    XO_c_requireobject_idx, 
    XO_o_defaultmethod_idx, 
    XO_o_init_idx, 
    XO_o_objectparameter_idx, 
    XO_o_unknown_idx

  * only XOTCL2:
     XO_o_cleanup_idx, 
     XO_o_residualargs_idx,

- Either transfer documentation for xotcl from @-notation to new doc system,
  or (maybe better) provide a renderer for @-structures to new doc system
  infrastructure (less work).

- do we need templates (such as object.html.tmpl) in installed docs 
  (currently nx*/doc/NextLanguageCore/assets/) it is confusing, since changes
  should be made to the templates in nx*/library/lib/doc-assets/.

- copy decls for objectMethod and classMethod  as comments
  to xotcl.c, fix and check order

- should we continue to work on the problem of the interp-aliased class,
  exported from one ns, imported into another one?

- should we extract parameter decls from pseudo-comments from the c source
  each time we change .decls, we have to change the c-code as well.
  /* *TCL*
  infoClassMethod superclass XOTclClassInfoSuperclassMethod {
    {-argName "class"  -required 1 -type class}
    {-argName "-closure"}
    {-argName "pattern" -type tclobj}
  }
  */
  we could preprocess xotcl.c and add code to the current .decls.

  OTOH: 
    * also doc would move into the c-code (maybe not bad)
    * we could not detect automatically changes in the decls,
      if these are generated from c, rebuild would have 
      to run for every compilation.

  Opinions?

- aolserver 
   * install
   * namespace collector (for blueprint)

- naviserver install

  1) ./configure --with-tcl=/usr/local/src/tcl8.5.8/unix/ --with-xotclsh --enable-symbols
     installiert nach /usr/local/aolserver/modules/tcl/xotcl.tcl

  2) kein "modules" beim ns
     sudo cp /usr/local/aolserver/modules/tcl/xotcl.tcl  /usr/local/ns/tcl/

- canonical reps: 
   "p:integer,multivalued" => "-name p -type integer -multivalued"
   "x:type,arg=::D d1" => "-name x -type type -arg ::D -default d1"
- use parameter syntax in genTclAPI

- info valuecheck?
- turn off optionally value checking
- get rid of "::xotcl::is"?

# TODO (optimization): optimizer can improve parameter checking:
#       (a) simple approach: make scripted setter methods on domain
#       (b) maybe nicer: provide arguments to c-setter to 
#           pass parameter definition

- the two flags "-objscope" and "-nonleaf" are for adding frames,
  and they are mutual exclusive. Make them a single flag?
  check if both options are in every case sensible.
- support -nonleaf for "dispatch" ?
  inf the following, we need just a frame, but not necessarily an "-ojscope"
  set x [::xotcl::dispatch $value -objscope ::xotcl::self]


 TODO: naming "type" and "mixin" not perfect.
#       maybe "type" => "hastype"
#       maybe "mixin" => "hasmixin"
#       => effects as well ::xotcl::is

- "ClassName info mixinof ?-closure? -registered_on class|object ?pattern?" 

- XOTCL_CMD_NOT_FOUND
- add all xotcl*cmds to C api, including importvar
- constants in type converter (in and out)

- genau genommen sind folgende info-Methoden unnötig:
  - obj info mixin
  - obj info filter
  - obj info class
  * obj info is
  - cl info mixin
  - cl info filter
  - cl info superclass

#if 1
  /* TODO: the following check operations is xotcl1 legacy and is not
