<- 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 refcounting 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 * check Options * info check * invar Conditions * info invar * instinvar Conditions * 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-object 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 " 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 object ?-type ? ?-hasmixin ? - 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 version (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 - extended regression tests - use namespace ::nx::test instead of ::xotcl::test - use namespace ::nx::serializer instead of ::xotcl::serializer - rename xotcl1.xotcl to xotcl.tcl - some cleanup (version variables, etc.) in xotcl.tcl - renamed tests/method-modifiers.xotcl to tests/method-modifiers.tcl - changed "require xotcl::test" to "... next::test" - changed "require next" to "... nx" - changed "require next::test" to "... nx::test" - changed "require next::doc" to "... nx::doc" - added missing ./tests/var-access.tcl to git - added section about registering filters and mixin to migration guide - moved and transformed to next tests/mixinoftest.xotcl -> tests/mixinoftest.tcl - moved and transformed to next tests/object-system.xotcl -> tests/object-system.tcl - changed pkgIndex reference for .so file from next ot nx - changed stubs from xotcl to nx - first part of openacs updates - changed "Serializer.xotcl" to "serializer.tcl" (package name from xotcl::serializer to nx::serializer) - added stub for xotcl::serializer for backward compatibility - changed serializer to new namespaces - renamed xotcl.tcl to xotcl2.tcl - added proc finalize to xotcl2.tcl - renamed mk_predefined.xotcl -> mk_predefined.tcl - renamed predefined.xotcl -> predefined.tcl - additional subcommand "info method parametersyntax " 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 - get forward definition from the original command - created own directory structure xotcl under library containing doc, tests, apps, lib etc. and moved obvious content here. - adjusted regression test and old documentation system to work with new structure old structure xotcl apps actiweb comm persistence scripts utils xml config doc library lib comm patterns rdf registry serialize store xml man tests unix win new structure nx config doc library lib serialize xotcl apps actiweb comm persistence scripts utils xml doc library comm lib patterns rdf registry store xml tests man tests unix win - 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?

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. -

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 -

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 - 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. - fixed a crash for tcl 8.6b1 in return value checking. now it complains about missing cmdPtr; it is not clear, why this is missing at the first place in 8.6b1 while working in 8.5 - improved library/lib/make.tcl once more - fixed handling of TclNRRunCallbacks, such that coroutines can be easily used (more testing required) - added temporary routine ::nsf::yieldcheck for coro debugging - renamed Tcl85showStack() to TclShowStack() - Big internal changes for handling nre-enabled procs in more situations.

We do not support it for "setter" and "attribute", since these require a parameter spec, which does not have clear semantics for a method path. - scripted definition of nx::Object.forward and nx::Class.forward - cleanup of __resolve_method_path - change TclShowStack into NsfShowStack() to avoid possible interference with the Tcl* namespace - made the following function static to avoid pollution of the global link namespace: CompiledColonVarFree(), GetRegObject(), ParamGetType() - changed option -expand in "info methods" and "info lookup methods" into "-path" to associate with the method path - changed method property name from "protected" to "call-protected" - changed nx::defaultMethodProtection to nx::defaultMethodCallProtection - nx::defaultAttributeProtection is used for scripted methods, forwarders and aliases - added nx::defaultAttributeProtection, used for setter and attributes TODO: - cleanup of xotcl-aol - method-modifiers/attribute-method.002: incorrect result for 'set _ {}' expected: '::C::A', got '' in test file ./tests/method-modifiers.tcl ... => FinalObjectDeletion obj 0x100915610 activationcount 2 Assertion failed: (object->activationCount == 0), function FinalObjectDeletion, file ./generic/nsf.c, line 15788. - use term "callprotection" in documentation for public|protected (to be consistent with info command) - extend coro regression test - serializer: * keep track of defaultMethodProtection * handing of xo::at_cleanup in serializer (either generailization or move to OpenACS/aolserver init/naviserver init) - interfaces in documentation for slots (see for more details ::nx::Class#superclass in nx.tcl). - nameing * namespace prefix next scripting language: ::nx::* next scripting framework: ::nsf::* * distributed packages in namespace ::nx::*, some are still in ::xotcl::* * names of subpackages nx::*, some packages are still xotcl::* * 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" - C-interface * generic/nsf.decls und generic/nsfInt.decls ausmisten (leere einträge weg, binärkompatibility mit xotcl nicht notwendig, da library anders heisst) * C-interface überarbeiten # SS: das wäre auch etwas für die post-alpha phase, oder? - 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) - 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? - 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). - 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.

It should be possible to turn the interpreter into a compiler to speed up argument passing. But maybe, this would bloat the code-size. * 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 * it could be possible to reduce stack frames in ensembles. Just a top ensemble frame could be sufficient. * the full names for ensemble methods could be stored in the cmd tables to make lookup faster.
