<- 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 -

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.

Change in performance for this call. >8 times faster before: parameters/parametercheck.007: 19.49 mms, ::nsf::is baseclass C after: parameters/parametercheck.007: 2.32 mms, ::nsf::is baseclass C - remove scripted definition of "baseclass" and "metaclass" - keep track of defaultMethodCallProtection and defaultAttributeCallProtection in serializer - cleanup aol-xotcl.tcl and document usage in aolserver and naviserver - iteration over TODO file - removed obsolete entries from generic/nsf.decls und generic/nsfInt.decls - removed NSF_CMD_NOT_FOUND - fixed aliasing warning for gcc 4.4.4 - removed CheckAllInstances() - added functionality to show enumerated values in "info parametersyntax" - extended regression test - added expermimental code to avoid "variable :x" crash based on shadowCommands, but this does not work, when varible is bytecompiled. deactivated for now. - added support for aolserver (essentially Makefile + aol-xotcl.tcl) - removed unneded content from serializer output - 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. possible realizations: -scope object|method -varscope instance|proc -varscope instance|resolver|none -frame object|method|default * instance|object: within this method, all non-prefixed var names refer to instance variables; the method can use most probably not "next" (actually, only needed for XOTcl) * method|proc|resolver: within this method, we can use colon-prefixed variables; the method can use "next" "object" könnte mit dem -per-object (dem registierungpunkt) leicht verwechselt werden. es ginge auch -varscope instance|method allerdings, meint method eigentlich "scripted method". "none" would be dangerous for "-frame", since it could imply to avoid frame stacking at all. effected are: alias, forward, dispatch für "alias" betrifft das in gleicher form auch die cmds, bei "dispatch" und "forward" gibt es dzt. kein "-nonleaf" - replaced "-objscope" and "-nonleaf" by "-frame object|method|default" for nsf::alias and nsf::default - added functionality for "-frame method" to nsf::dispatch - made the order of argument in ::nsf::alias and method "alias" the same (always first the method, then "-frame ...") - extened regression test - renamed some arguments of tcl interface to increase consistency - make requiredness explicit for nsf::cmds - introduce ::nsf::parametersyntax to provide syntax for potentially missing definitions - provided ::nsf::parametersyntax for 3 ::nsf commands and 7 nx methods (from relationslots) - fix requiredness of several info methods - added "nsf::configure debug ?level?" - use "nsf::configure debug" for value 1: compain about protected value >1: provide load messages for nx and xotcl - unset unneeded variables in ::nx namespace - copied decls for objectMethod and classMethod as comments to nsf.c, fixed order - documented a few functions - enabled nsf::__db_run_assertions in nx::test (lead before to false posigives in destroy-test) - eliminated deleted objects and objects from deleted namespaces in GetAllInstances() - added handling of unstacked csc entries (removed all DEBUG warnings). - made handling of unstacked entries optional by defining macro CHECK_ACTIVATION_COUNTS) - added macro NSF_DEVELOPMENT for toplevel handling if NDEBUG and CHECK_ACTIVATION_COUNTS - cleanup of method-modifiers.tcl - updated next migration guide - follow current Tcl vonvention for patchlevel var: - changed name of ::nsf::patchlevel to ::nsf::patchLevel - changed content ::nsf::patchLevel from eg .0 to full number including release details - fixed bug in ::variable with colon-prefixed name (shadowCommands does not help, see above) - removed traces of Nsf_VariableObjCmd() - extended regression test - provided parametersyntax definitions for XOTcl 2.0 similar to nx for all methods without a spec (e.g. fur builtin Tcl cmds, forwarders) - make sure not to return CompiledLocal vars from InterpColonVarResolver() when TCL_NAMESPACE_ONLY is requested. - delegate always from InterpColonVarResolver() to other resolvers, when TCL_NAMESPACE_ONLY is requested. - implemented exported command ::nsf::self as fast conveniance replacement for "::nsf::current object". - removed bug-alert from nx.tcl (wrong false-positives for compiled locals in slots) - added a few small optimization. nsf appears to run on the shootout benchmark the same speed like a year ago (which much less functionality) - added a few more small optimization. - code-generator: don't call argument parser, when no arguments are specified - fixed bug when calling aliased proc not via method interface - fixed bug when calling destroy in initcmd - allowed public|protected for method deletion such as "Object public method foo {} {}" - removed defaultMethodCallProtection in alias test - extended regression tests for aliases to procs - renamed nx regression tests .test to follow tcl conventions - added regression tests for destroy-during-init - removed debugging from NsfCleanupObject when compiled without DEVELOPMENT - removed debugging from CscFinish when compiled without DEVELOPMENT - changed CallStackGetActiveProcFrame() to return also CMETHD frames This allows to execute :volatile in a initcmd and to delete the object at its end. As a consequence, code like [CopyHandler new -volatile] copy [::nsf::self] $newName has to be changed to CopyHandler new { :copy [:uplevel ::nsf::self] [uplevel set newName] :destroy } - renamed CallStackUseActiveFrames() to CallStackUseActiveFrame() and ctx->framesSaved to ctx->frameSaved to reflect implementation - new function MethodNameString() to obtain name without colon prefix from tcl_obj - fix bad interaction between filters and cmd name resolvers - output object frame to ease interpretation of [info frame] - fixed scoping issue, when "-volatile" was used for object creation - added regression test for interaction between filters and function resolver (and volatile) - reactivated new volatile test in destroy.test - undone temporary fixes for volatile in serializer and nx.tcl - impoved NsColonVarResolver, made some assumptions explicit - gentclApi.tcl: added optimizer rule for single argument of type tclobj - improved speed of CompiledLocalsLookup slightly - added an experimental code for setting parent namespace path as default for child-objects. At the time when an object namespace is created, the namespace path of the parent object is copied to the child as default value. - added new contains definition based on "apply" instead of "namespace eval". Main intention is to replace SKIP_LEVELS by SKIP_LAMBDA - added functionality to use ":attribute contains:method,nosetter" - added regression test for contains and attributes of type method - activated SKIP_LAMBDA in nsfCallstack. As a consequence, we disallow resolving self/my ... from tcl-proc frames (use uplevel if necessary, avoid "namespace eval") - improving error messages from argument parser - test "namespace current" and "self" in "contains" and "slots" regression test - added "nosetter" automatically, when attribute ":method" is used - fix a bug, where "o configure" (without arguments) resetted initialied values to the defaults. - show "unwind unstacked entry" message appear only when debug level>0 - removed fixed TODO entries - New function NsfNamespaceInit() to initialize pre-existing namespaces in PrimitiveOInit() and in RequireObjNamespace() - provide error message, when provided setter name starts with a colon - Make sure that DispatchDestroyMethod() calls as well protected destructors - New function NSCheckNamespace() as replacement for NSCheckForParent() - pass parentNsPtr around instead of recomputing it in NSCheckForParent() - removed unneeded argument from NSGetFreshNamespace() - switched to dstring operations in NameInNamespaceObj() (seems slightly faster) - factored out NSRequireParentObject() - by the measures above, we obtained some speed improvements - moved some more debug output to be controlled by the debuglevel - extended regression test with testcases for creation of parent objects via method "__unknown" - disallow object parameter of type "switch" to avoid possible confusion between (a) providing a value for the o.p., (b) calling it as a setter, and (c) calling it as a getter. For providing a value, no arg is used for switch. For calling a setter, it is necessary to provide a value even for a switch. - disallow type "switch" in setter definiton (use boolean instead) - disallow type "switch" for positional arguments (use boolean instead) - extended regression test - configure.in: removed --with-tclinclude option, since it appears to be included in tcl.m4 (since a while). Many thanks to Victor Guerra for noticing it. - perform relation handling in objectparameters outside of object-frame - For preexisting namespaces, we do not set the deleteProc. Is this desired? Should nsPtr->deleteProc be moved to NsfNamespaceInit()? .... It is ok on the current labor distribution between object and namespace: if an object is deleted, it takes care about the deletion of subobjects, not the namespace. However, it might be an option in the future to overthink this strategy and to bush (sub)object deletion into the namespace deletion. - work on replacing SKIP_LEVELS by SKIP_LAMBDA for openacs (works with regression test, has problems with OrderedComposite::ChildManager.init) Note concerning treating CMETHOD_FRAME like METHOD_FRAMES: we did this change for NsfCallStackFindLastInvocation(), but nsfStack.c has still several occurences, where they are treated differently. - changed relation handling by evaluating the relationcmd in the parent context to keep evaluation order. - extend introspection "nsf::configure objectsystem": the command returns now all system methods in the syntax of nsf::createobjectsystem - "nsf::createobjectsystem" creates now a warning when an existing objectsystem is redefined and ignores the new definition attempt. This was done with the purpose to allow "package forget nx; package require nx" - Allow overwriting of redefine protected method during bootstrap to ease "package forget nx; package require nx" - forward had just "-objscope", no general "-frame method|object". Since forwarder have client data, they always push a method frame. So, the situation is different to nsd::alias and ::nsf::dispatch. Therefore, the flag "-objscope" was renamed to "-objectframe" to provide better consistency with "-frame object" - fixed bug, where error handling of invalid options in ForwardProcessOptions() could lead to a crash - return forwardoption "-earlybinding" via instrospection - extended regression test - provide a more explicit way to handle resourcing after a "package forget" in the info methods (similar to Stefan's suggestion). - xotcl2.tcl: added empty namespace eval to make package indexer happy - nx.tcl: removed debugging output - nx.tcl: added syntactic sugar to "method" and "alias" for return value checking. One can write now: Class create C { :public method foo {a:int b:int} -> int { return [expr {$a + $b}] } } - extended regression test - changed returns syntax from '->' to '-returns' - xotcl2: fixed and completed results of "info instforward" and "info forward" - serializer: fixed handling of nsf::configure options - nx: added "-returns" to forwarder - added regression test for forwarder and returns - rebuild pkgIndex.tcl more eagerly - added error handler to pkg_mkIndex when called via "make libraries-pkgindex" * just show warning and errors when rebuilding pkgIndex files * stop make in case of errors in pkg_mkIndex - don't leave error message when __default_superclass (or __default_metaclass) is not set - Fixed switching between INACTIVE_MIXIN frames to ACTIVE_MIXIN frames - Extended regression test - make handling of redefinitions in system methods more robust - follow Tcl naming convention (uppercase functions) - Don't allow to call objects as methods (for the time being) via absolute names. Otherwise, in line {2} below, ::State is interpreted as an ensemble object, and the method "unknown" won't be called (in the XOTcl tradition). {1} Class ::State {2} Class ::State -parameter x - Converted migration guide to asciidoc - Overhaul of several sections in asciidoc - Developed styles for nx for migration guide (.css and source-highlight) - fixed bug in xotcl 2.0 "info forward" - extended regression test - NSDeleteChildren: delete objects before classes - NSDeleteChildren: delete here aliases as well - fix potential crash when "next" is called from a non-proc frame. - nx.tcl: cleanup of forward implementation - xotcl2.tcl: cleanup of forward implementation - xotcl2.tcl: provide debug version of default init method - nsf.c: acquire parameter structure for returns more lazily (otherwise, a serializer handling returns would acquire the structure for every argument) - extend regression test - xotcl2.tcl: fix the default init handler - nsf.c: provide warnings when unchecked parameter values might conflict with nonpos args - provide a generic logging interface * predefined for plain Tcl and aolserver/naviserver * C-level: NsfLog() * Tcl-level: ::nsf::log - quote name of referenced parameter in error message to ease reading - new parameter checker "parameter", performing an approximate checking for valid parameter specs - set NSF_ARG_CHECK_NONPOS only when there are multiple arguments - remove space checking in values for NSF_ARG_CHECK_NONPOS in favor of parameter checker - make "... info children ?pattern?" compliant with XOTcl 1; if pattern contains no wildcard and is no absolute path, nsf completes it. (eg. Object create o; Object create o:x; o info children x" will return ::o::x) - extended regression test - introduced a few forms of multiplicity * 0..1 allow empty value * 0..* list, can be empty (equivalent to 0..n) * 1..* list, cannot be empty (equivalent to 1..n) - deprecate multivalued in parameter specs in favor of multiplicity - deprecate allowempty in parameter specs in favor of multiplicity - adjust regression test - fixed bug with required last object parameter without provided value - extended regression test - new printf-style error message generator: NsfPrintError() - simplified error handling: removed NsfVarErrMsg() and NsfErrMsg() and replaced it by NsfPrintError() - testx.xotcl: fix messages when test fails - further cleanup of error procs: eliminated NsfObjErrArgCnt() - improve error message, when too many arguments are passed - extended und overworked migration guide (added e.g. multiplicity) - extended regression test - added returns handling for nx in serializer - extended regression test - provide warning if non-positional argument is passed more than once - made error messages more consistent - improved error messages for "returns" and "nsf::is" (omit parameter name) - streamlined error messages - removed NsfErrBadVal() and replaced it with a generalized version of NsfObjErrType() - "/obj/ info method parametersyntax /method/": return results of ::nsf::parametersyntax in case, the parametersyntax cannot obtained from a parameter definition (e.g. the method is a forwarder to a tcl cmd). doctools - interfaces in documentation for slots (see for more details ::nx::Class#superclass in nx.tcl) - handle object methods as well in quality checks - why does one have to specify @superclass rather than determining the superclass via introspection? - use tcl parametersyntax for short description of commands/methods - deal with interally-called methods (can be overloaded by the application) * user-called and internally called (e.g. from "create" or "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, text - use term "callprotection" in documentation for public|protected (to be consistent with "... info methods ...") - reduce indenting for code examples in documentation (high indentation makes readability worse). i use usually just 2, 4 are ok as well; we should decide. - removed method "setter" from nx - removed method "setter" from migration guide - nx method "attribute": changed name of nonposarg from "slotclass" to "class" - fix bug for "C class-object attribute foo" (incorrect forwarder) - extended regression test - doctools: changed "-slotclass" to "-class" - nx::test: made differences in regression test easier to read - serializer: updated serializer to avoid calls to "setter" - extended regression test - fixed in bug in ensemble-next (removed colon-prefix from methodname in next) - extended regression test - Experimental Object-System specific resolver in method bodies (allows resolving to the "right" next, self, etc. without namespace imports/paths) - deactivated automatic namespace path copying for child-objects - extended regression test - added deletion functionality to nsf::mixin - moved handling of methodNames of c-cmds to ResolveMethodName() - extended regression test - nsf.c: renamed MethodNameString() to MethodName() (for consistency with ObjectName() and ClassName()) - raise error, when "obj :method ..." is invoked (colon misleading und not necessary) - remove colon from method name in error message "unable to dispatch method ...." - extended regression test - nsf.c: code cleanup and documentation improvements - made assertion code optional - added and renamed additions compile flags NSF_WITH_INHERIT_NAMESPACES NSF_WITH_OS_RESOLVER NSF_WITH_ASSERTIONS - added flag NSF_WITH_VALUE_WARNINGS - defined nsf::deprecated as tcl proc, using ::nsf::log - some minor refactoring - "info parameter": return :switch as parameteroption for C-defined cmds, when a nonpos-arg gets no arguments - updated regression test - added experimental ::nsf::proc for realization of procs with next scripting argument passing. These nsf::procs improve the orthogonality of the code (using e.g. nonpos args and value checker for procs) and allows the same introspection interface (info method parameter|parametersyntax, ...) - removed unneeded functions: NsfComputePrecedence(), NsfComputeDependents(), Nsf_SetVar2Ex(), NsfOSetInstVar(), Nsf_ObjGetVar2(), NsfOGetInstVar(), qNsfCreateObject() - removed unneeded external declarations: NsfClassListAdd() NsfClassListFree() - make extern declarations explicit - grouped most extern definitions together - improved documentation - moved variable declarations to inner scopes - removed warning from cppcheck() - added block for none-one-liner if statements - added methodtype "nsfproc" to "... info methods ...", to be used with namespace qualified names - return "nsfproc" as methodtype for nsfprocs - refactored InvokeShadowedProc() - some minor code cleanup and improved documentation - added flag "-ad" to ::nsf::proc for obtaining the semantics of ad_proc in OpenACS (boolean with no arguments, append "_p" to variable names) - added "... info method definition ..." for nsfprocs - new function DStringAppendQualName() to append qualified name to a DString - removed obsolete function NSCmdFullName() - serializer.tcl: export nsf::procs via "Serializer all" - nsf::proc: alloc shadowed methods in ::nsf::procs - new helper function ::proc strip_proc_name to strip nsf::procs prefix - improve error messages - reduce verbosity - removed the following obsolete macros: ALLOC_NAME_NS, ALLOC_TOP_NS, ALLOC_DSTRING - some refactoring of the argument parser - argument parser handles now as well OpenACS like single-word parameter values (such as ... -flag=1 ....) - improve error messages and warnings for nsfprocs - extended regression test - no need to define "-class" as objectparameter - no need to define "Object.cleanup" as a method - let "obj class NEWCLASS" return NEWCLASS - doc-tools: added "-where" to !get - doc-tools: title to internal links, provided css class, added nicer label - updated reference doc - removed leftover -public flag in nsf::method - general cleanup: removed unused arguments - defined UNUSED macro to get more checking on unused arguments - nx::pp: added flag "-linenumbers on|off" to render method - added first version of next-tutorial.[txt|html] - xotcl2.tcl: defined ::xotcl::MetaSlot - make sure, that classes of the intrinsic class hierarchy are of the same object system - add regression test - removed c-implementation of method vwait, it was replaced by "vwait :varName". We had to allow flag TCL_GLOBAL_ONLY in InterpColonVarResolver(), since Tcl vwait implementation calls it with that flag. - added a scripted implementation for vwait in xotcl2 - added regression test for vwait - removed TCL_VWAIT from the code, since we have it in git - nx.tcl: defined method unknown as protected - nx.tcl: never pass "substdefault" to a setter - nx.tcl: define a minimal valuechecker any to suppress warnings for potential conflicts with non-positional parameters, when the values start with a dash - doc-tools.tcl: make -name parameter of method new always required and "any" - doc-tools.tcl: make object parameter of Entity of type "any" - nsf.c: added wideinteger to list of valuecheckers - nsf.c: provide context for warning messages - extended regression test - next-tutorial: documentation updates - add explicit reference counting for oacs-style flag value passing - parameter specs: use "arg=" in object parameter type "method" as name of a called method to allow to call unregistered methods - eliminate protected method "noinit" for nx and allow it just as an object parameter - added first implementation of object parameter type "forward" - renamed object parameter type "method" to "alias" - removed parameter option "slotobj=" in toParameterSyntax - renamed to [from|to]parameterSyntax to [from|to]parameterSpec - serializer.tcl: reactivated methodSerialize (used in api-browser of OpenACS) - nx.tcl: * new method requireClass to Combine two classes and return the more specialized one * make slot objects for parameter aliases and parameter forwarder instances of ObjectParameterSlot * get rid of attributes "isforward" and "isalias" and replace it by "dispositon" * complete list of predefined value checkers * we have now three approaches for providing parameter -object-filter and -object-method Approach 1: create RelationSlot with nosetter Approach 2: use parameter forwarder Approach 3: use parameter alias we switched from approach 1 to approach 3 - extended regression test - fixed potential crash with missing parent namespace - added shadowing for ::tcl::info::body to allow "info body" to be called on ::nsf::procs - commented nsfShadow.c - added regression test - removed NSF_INFO - fixed potential access to freed memory (actually when checking if namespace was removed by Tcl); found this problem when compiling Tcl with SYSTEM_MALLOC (own modified version of tclThreadAlloc.c) - fixed memory leak (namespace names and structures) - nx.tcl: * full rewrite of slot machinerie, much simpler structure * relation handling via parameter aliases instead of pseudo converter * mixinclass SlotOptimizer removed * new class BootStrapAttributeSlot - ConvertToRelation() and handling of parametertype "relation" - Make CompiledColonVarFetch() more robust in case of half initialized objects (create vartable on the fly if needed) - allow empty parameter options in parameter parser - removed nsf::parametersfromslots (became simple, part of objectparameter now) - removed hardcoded objectparameter (attributes, volatile and noinit) - updated regression test - updated class diagram - nx.tcl: needsForwarder is true, when method "get" is specified on a slot - nx.tcl: Don't generate per-slot add/assign handlers, when not needed - nsf.c: fixed a nasty bug within namespace deletion, when a deletion of one tcl cmd caused implicit deletions of other cmds in the same namespace. The classical idiom for looking over hash tables with Tcl_GetHashValue() and Tcl_NextHashEntry(hSrch) can lead to crashes (and has different behavior depending on the number of buckets). - added regression test - nx.tcl: added default/initcmd for ObjectParameterSlot - added ::nx::Object as default for "superclass" slot to make default superclass explicit - unified interface for getParameterOptions - extended regression test - update class diagram of slots - new function Nsf_NextHashEntry() simular Tcl_NextHashEntry(), but handles triggered hash entry deletions - fixed reference count in AliasDeleteObjectReference() - nsf.c: changed handling of cmdPtrs in callstack content. * we use now explicit reference counting using NsfCommandPreserve/NsfCommandRelease * as a consequence, we do not need the following functions Nsf_DeleteCommandFromToken() and CallStackClearCmdReferences() any more. * the flag NSF_CSC_OBJECT_ACTIVATED is not needed anymore and was removed - removed a small memory leak when a destroy method of an object o deletes its grandparents namespace, containing also this class of o (and its methods). Significantly eased by the change above. - use NsfCommandPreserve/NsfCommandRelease for tcd->aliasCmd as well. In case of epoched cmdPointers, refetch the cmd and it client data. - added regression tests - added flag to AliasGet() to leave optional error message if alias data is removed - some cleanup in NsfProcAliasMethod(): handle not existing alias data, more careful refcounting - added experimental flag WITH_IMPORT_REFS to deactivate automated alias deletion (seems, that this solves all issues we had before) - added flushing of bytecode on alias registration - added regression test - update slot uml diagram - fixed incorrect (unwanted) call to unknown that caused creation of objects names __unknown when classes could not be resolved - nsf::relation: fixed error message when receiving and invalid class for relation type "class" - updated documentation - reanimated NSF_PROFILE (when activated, needs more stack and slows execution slightly down) - fixed a problem with object-level alias - nsf.c: provide low-level commands for managing profile data - nsfStack.c: provide hook to obtain callers information in profiling code - nx.tcl: provide caching for computed values of object slots to make method objectparameter nearly twice as fast; direct changes on slots require a reconfigure call. - nsf.c: removed SUBST from shadow commands (does not appear to be necessary any more) - nsf.c: fixing a memory leak (some substituted values were not freed correctly) - nsf.c: fix potential crash for epoched cmds - some minor updates for profiling support - The fix of yesterdays subst reference counting bug triggered an other problem: If the last arg was "args", the flags array for checking the need for decr of refcounts was not extended. There are multiple possible fixes, i have just extended the flags array for now as well. - When profiling is activated, perform now a more sane shutdown order, all hash tables are now correctly freed. - Improve behavior, when object system creation fails - Drop function NsfProfilePrint() - Altered Nsf_NextHashEntry() to re-init hSrchPtr when the number of expected entries differs from the number of real entries. This fixes a bug that Michael Aram detected, that happens when multiple hash buckets exist, but on deletion of an hash entries triggers some other deleted from the same hash table. - extended regression test. - made default setting more compatible with XOTcl 1 * set variables to defaults only when not set already * flag init_called already before init is called, not afterwards (a call to "configure" within init does not clear the already set instance variables) - extend regression test - configure: added flag --with-profile to enable profiling support - cleanup and documentation of nsf-specific interp state - nsf::configure: added an option "profile on|off" (per default off) - profiling: return object data with method information - the following is obsolete since valgrind 3.6 =========== reminder for valgrind testing svn co svn://svn.valgrind.org/valgrind/tags/VALGRIND_3_5_0 valgrind curl http://bugsfiles.kde.org/attachment.cgi?id=36999 > 10.6.patch mv 10.6.patch ./valgrind cd valgrind patch -p0 < 10.6.patch ./autogen.sh ./configure ./configure --build=amd64-darwin make sudo make install ==================== - doc: * This package contains 12 classes.... 3 objects ....

otherwise default values for slots would not be available * reduced verbosity of parameter forwarder * Hopefully the last big naming change: Instead of writing "C class-object method foo {} {...}" one can write now "C class method foo {} {...}" to define a class method named "foo" for class "C". This naming change became possible by defining XOTcl's "class" (and "superclass") as object parameter only. To change a class of an object o, one has to use "o configure -class NEWCLASS". The term "object-class" looks alien to language beginners, the term "class" is much more straightforward. Changing classes or superclasses is seldomly used by typical application programs. For already existing nx scripts, changing "object-class" into class should be straightforward. * various documentation updates (migration guide, nx tutorial) * fixed bad interaction between filter and parameter alias * some documentation/todo updates * fix compilation for tcl-head in fossil * deactivate coro regression test, since it is apparently broken for tcl-head in fossil (stack frame seems to be lost after a yield) * make sure to create the cmds for objects with Tcl_NRCreateCommand() to choose trampoline-path in the trunk version of Tcl * The newest trunk version of Tcl in fossil has TclStackFree() and TclStackAlloc() removed We had to substitute this functions. Unfortunately, the lifetime of the strack structures has changed, so we had shuffle some internals around. - nsf.c: remove unnecessary test when compiled without NRE - nsf.c: make sure, validCscPtr is always initialized - tested all regression tests with valgrind against tcl-trunk - gentclAPI.tcl: * renamed "nsfCmd" to simply "cmd", since the code can generate arbitrary tcl commands * allow type "int" in the .decl files - nsf.c * move several functions from "static" to "external" to make the code generator usable for submodules as well - added flag ?-type ...? to "info lookup slots" - made all useful converters external symbols - added flag ?-type ...? to "info slots" - delete accessor when slot is destroyed - added pattern to "info slots" - added to "info slot /attName/" - Fixed dispatch of defaultmethod for ensemble methods - Added compile flag DISPATCH_ALWAYS_DEFINED_METHODS (deactivated). So far, nx just uses dispatch on overloads or filters, but not on defines (possible to call e.g. "destroy" from a script, but internally the direct dispatch is used, as long there is no overload). The compileflag would force to use the slower dispatch always. - Extended regression test - Improve locality - Let "info slot" return the slot object - nx::mongo: Initial commit of the experimental mongoDB interface for nx - nx.tcl: fix handling of arg in converter - nx::mongo: * first step towards handling embedded objects * one more example script: example-nx-bi.tcl - nsf:c: fix dispatch of setter without current method - extended regression tests - nsf.c: added nsf::var::unset (provided so far just var::set) - nx::mongo: * added mongo::count * obtain _id from mongo::insert * added mongo::Object.delete method for embedded and non-embedded objects * handling of mongo-embedded objects when destroying objects * simple bson pretty print function * extended examples * handle fetch of embedded objects * added method count for mongo mapped classes * improve documentation * added handling of bson types for timestamps and dates * provide setup based on mongo_db, mongo_collection and mongo_ns * implemented type "reference" similar to "embedded" * all referenced objects are for the time being auto-dereferenced * new method "show" for mongo mapped classes * added two new example files example-nx-reference-many.tcl and example-nx-reference-one.tcl * replaced "arg" by "type" in spec for mongo attributes to make spec less strange - nsf.c: made potentially unknown clientData more safe (error message, when something is passed via clientData to a method expecting an object/class as clientData). - renamed NsfNoDispatchObjectError() to NsfDispatchClientDataError(), extended interface - Makefile.in: fixed name methods.test - nsf: renamed nsf::isobject to nsf::object::exists - nsf: renamed nsf::qualify to nsf::object::qualify - nx.tcl: added support for positional object parameter and removed special handling of the last argument for the init block; added attributes "position" and "positional" to ObjectParameterSlots, removed last argument of method "objectparameter" - nx.tcl: simplified createBootstrapAttributeSlots (second round of default value setting seems not necessary) - nx.tcl: some cleanup - test.tcl: * don't export Test per-default * define Test as nx::Test * make Test parameter count 1 the default, change to higher numbers where needed - nsfmongo.c: * upgrade to newest c-driver (version 0.3) from git. * support connection to replica sets * support attribute selection lists for ::mongo::query (positive and negative selection) - nx-mango.tcl: * support for unique indices * support for query operators "in" and "all" - extended migration guide (introduction, feature lists, etc.) - serializer: * prefix warnings to ease tracking of warnings * some cleanup for handling aliased methods - nsf.c: * moved implementation of ::nsf::method::delete to C * produce same error messages when methods are delete via nsf::method::delete and nsf::method::create {} {} * Prohibit deletion of methods during shutdown. Otherwise when destructors delete methods, some other destructors depending on these methods will fail. Cleanup deletes all methods anyway. * Provided alternative (faster) way of dispatching nsf::procs (can be tured off with NSF_INVOKE_SHADOWED_TRADITIONAL) * renamed NsfMethodCmd() into NsfMethodCreateCmd() for consistency * nsf works with OpenACS again (requires new nstrace.tcl, aolserver-openacs.tcl, and 01-debug-procs.tcl). - nsf.c: * factor out NsfClassListAddPerClassMixins() * factor out NsfClassListFind() * let result of "cls info heritage" return per-class mixins as well, otherwise it would be useless, since "cls info superclass -closure" would return the same * replaced loops with NsfClassListFind() - nsf.c: * handle direct dispatches for aliased methods * new generalized error message: NsfNoCurrentObjectError() - nx.tcl: replace loops ::nsf::methods::[object|class]::* by explicit command registrations - nsf.c: * added NsfClassListNoDup() to allow just single inserts * added NsfClassListPrint() for debugging * info heritage returns no duplicates * added prototype for NsfNoCurrentObjectError() * report "no current object" when no object is passed to a method. * code cleanup - extended regression test - nsf.c: * ensure that explicit per-object-mixins are kept at the front in "info heritage" order and in "info precedence" when classes are added as POMs and PCMs * extended regression test - nsf.c: * renamed old flag "-order" of "info mixin classes" to "-heritage" since it computes same heritage as in "info heritage" (but potentially for a list of classes) * added compatibility layer for xotcl2 * added lost option "-heritage" to "/cls/ info mixin classes" (was only there for "/obj/ info mixin classes") * extended regression test - nsf.c * first version of c-bases "info slots" for classes * switch "-closure" just for class info method * added switch "-source" to "info slots -closure" and "info lookup slots" (similar to "info lookup methods") * extended regression test * base objectparameter on "info slots" - nsf.c * added "pattern" to "info lookup slots" * added "pattern" to "info slots" * extended regression test - nx.tcl, xotcl2.tcl: removed unsafe {*}$pattern - added: "info slot handle /name/" "info slot parameter /name/" - nsf.c: Since the method "objectparameter" is just based on the class (and object parameters are invalidates as well over the class), we moved the method from obj to class to avoid potential confusions - nsf:c * added C-implemented class level method "info objectparameter list|name|parameter|parametersyntax" * added enum to handle different print styles for parameters * renamed ParamDefsList() to ParamDefsNames(), added true ParamDefsList() - nx.tcl: * removed "info slot handle" and "info slot parameter" * added "info parameter spec", "info parameter list", "info parameter name", and "info parameter syntax" * extended regression test - nsf.c: * Added argument "-reg-object" to ::nsf::method::create to distinguish between a registration and a definition object for ensemble methods, similar as on other places. If no reg-object is provided, it is the same as the definition object. One should take care that the registration objects are deleted after the definition objects, which is the case for the usages of the reg-objects in nx/xotcl. * The namespaces within plain scripted methods and scripted ensemble objects are now the same. * Extended regression test * Code cleanup and documentation - nx.tcl: * added method "delete" to delete methods and attributes * extended regression test - nsf.c: removed all but one occurrence of Tcl_AppendElement() - nsf.c: removed all occurrences of Tcl_AppendElement() - nsf.c: passed around resultObj explicitly - nsf.c: fix and document GetMatchObject() - extend regression test - nx.tcl: * splitted method "delete" into a "delete method" and "delete attribute" * remove flag "-per-object" in method "delete" * delete per-object methods of classes with "/cls/ class delete method name" and "/cls/ class delete attribute name" * extended regression test - added test cases for "info slots" - nsf.c: * handling of same named per-object and provided slots for Class objects * per-object slots are saved now under ::per-object-slot::* * returning correct results when per-object slots are used * removed obsolete functions: NsfObjectListFree(), NsfObjectListAdd() * removed obsolete type NsfObjects * transformed ComputeSlotObjects() into a more generic AddSlotObjects() that can handle per-object slots as well - nx.tcl: * generalized slot object handling. * extended regression test - xotcl2:tcl * made "info heritage" in xotcl2 compatible with xotcl1 * fixed "info slots" in xotcl2 * extended regression test - nsf.c: require NSF_IS_SLOT_CONTAINER for slot-container - nx.tcl: ne proc ::nx::setSlotContainerProperties to handle slot container properties in a uniform way - reduce verbosity - nx.tcl: improve code documentation -nsf.c: added c-implementation of "/object/ info slots" to share implementation details and reduce scattering - migration guide * included change in "info heritage" * included "info slots" * included "info parameter" * included "delete method" * included "delete attribute" - nsf.c: NsfRelationCmd() returns per default list of actual values, therefore mixin add|... return now as well the actual values - nx.tcl: added "info parameter slot" to return slotobject(s) - added "info parameter slot" to migration guide - extended regression test - nsf.c: changes to use trunk-branch with and without TclStackAlloc() - migration-guide: add third level to toc - fix regression test for 8.6 to use nx prefix - nsf.c: added cmd "::nsd::method::registered /handle/" that returns the object on which the method identified by the handle was registered, or empty. - extended regression test - bring defined commands in the source code in alphabetical order - generate interface for NsfUnsetUnknownArgsCmd() - delete some obsolete code - added "link" from 2.4 (parameters) to "info parameters" in migration guide - remove alias warnings from gcc under ubuntu (4.2.4) - nsf.c: fixed possible crash in tcl8.6 with nsfprocs, still one inconsistency - nsf.c: fixed bad interaction between mixins and ensembles in tcl8.6 - nsf.c: document two more functions - nsf.c: removed unneeded casts to (ClientData) - nsf.c: generalized disposition handling (forward, alias, initcmd) for object parameter * disposition is now an option for object parameters rather than than an own type. Therefore, one can check the arguments passed to the disposition cases * changed specification of name of method from arg= to method= * this way "type" info in "info parameter syntax" is handled automatically - nsf.c: * added a new converter for converting mixins with guards (named mixinspec) * used mixinspec in nx.tcl and xotcl2.tcl * extended nx regression test. * added profiling support for nsf::proc when NSF_INVOKE_SHADOWED_TRADITIONAL is turned off. - removal of unneeded flags "-incontext" and "-nomixins" from * /obj/ info methods * /cls/ info methods These flags are correct for "info lookup", but unneeded for "info methods" - cleanup of ListDefinedMethods() - nsf.c: use NsfObjectRefCountIncr() instead of object->refCount++ - nsf.c: fix small memory leak for nsf::is in error cases - renamed converter from "mixinspec" to "mixinreg" - Use mixinregObjType as well in NsfRelationCmd(), so this is the only place, where mixin and guards are processed. - Since the type converter converts Tcl-Objs, we have less context information (e.g. we have no base class, on which we can decide to call e.g. __unknown on on of the objects systems). - because of the point above, i removed ::xotcl::Class->__unknown and ::nx::Class->__unknown in favor of a global proc ::nsf::unknown, for which unknown handlers can be registered - GetClassFromObj() receives as last argument "withUnknown" instead of baseClass to indicate, when unknown should be tried. - new function NsfCallUnknownHandler() - moved mixin reg type converter to a new file (nsfObj.c) - added NsfFilterregObjType, to provide a converter for filter registration similar to mixin registrations - replaced dummy dupIntRepProc and updateStringProc in nsfObj.c by NULL - fixed memory leak in "... info mixin classes -heritage" - added tests for integer, wideinteger and bignums - added value checker type int32 (similar to "string is integer") and changed value checker "integer" to accept all integers - library/mongodb: * use type int32 * updated to new nx/nsf interfaces * updated for mongo-c-driver post 0.3 (supporting result MONGO_OK for mongo_cursor_next) * factored out "mongo cond" from "mongo query" - fixing part of the memleak introduced for bignum handling above (for some unknown reasons, we see crashes from mp_clear) - extend regression test - improve bignum conversion handling further - found memleak in tcl - provided nicer registration and inspection interface for unknown handlers - added documentation for unknown handlers in tutorial - cleanup of __unknown - added handling for provided arguments to positional object parameters with disposition alias and forward - provided better error messages for unknown parameter options - provided error messages for multiple disposition parameters - reduce redundancy by introducing macro NSF_ARG_METHOD_INVOCATION - gentclAPI.tcl: * renamed "nrArgs" to "nrParams" * switched default for nrargs from 0 to 1 - gentclAPI.decls: * added "-nrargs 0" where needed -nsf.c: * switched parameter logic from default for nrargs from 0 to 1 * simplified logic to detect additional arguments in argument parser * improved error message for missing required argument - regression tests: * added disposition.test * extended regression test - xotcl2: use filterreg instead of plain arg for registration of filters - nsf.c: * improved source code documentation * added parameter option "args" in order to get eventually rid of hard-wired call to residualargs. * improved a few error messages * fixed object parameters consisting only of plain parameters (previously, no parameters were returned in this case, e.g. for method parameters; but object parameter code depends on it) - extended and updated regression tests - nsf.c: * added refcounting to parameter definitions (needed, when aliased object parameter redefined the actual objectparameters) * removed hardcoded call to remaining args * switched implentation of xotcl2 to use object parameter with parameter option "args" * removed residualargs from object system definition * extended regression test - nsf.c: * Don't output non-consuming procs (which are always called) via parametersyntax (shows, what a user can input) * additional command ::nsf::object::initialized to check whether an object is already initialized * new function DispatchInitMethod() similar to DispatchDefaultMethod() * let residualargs call init directly instead of doing it the inidrect way * provided ability to call init with object parameters at arbitrary times * switch from Tcl_ObjCmdProc style interface (ClientData first) to a C stype interface for DispatchDefaultMethod(), DispatchUnknownMethod() * bring cmd definitions for nsf::object in right order - extended regression test - genAPI.decls and nsf.c: bring cmds in same order - nsf.c: align naming conventions - renamed gentclAPI.decls to nsfAPI.decls - renamed tclAPI.h to nsfAPI.h - added nsf.m4 to git for the time being - mongdb: * added preliminary gridfs interface * refactored some code * added new types for "gridfs" and "gridfile" * added new example file example-nsf-gridfs.tcl - nsf.c: no good reason to disallow user defined types for for alias, forward or initcmd - library/nx/nx-zip.tcl: added a zip file generator as package - nsf.c: * new file nsfPointer.c * generic new value checker ConvertToPointer to handle c-level conversions (which can be registed from nsf extensions) * extern defined interface for the pointer converter: Nsf_PointerTypeLookup(), Nsf_PointerTypeRegister(), Nsf_PointerAdd(), Nsf_PointerDelete(), Nsf_PointerInit(), Nsf_PointerExit(). - library mongodb * changed mongoAPI to pointer converter interface - C-code generator: * additional parameter swith "-withObj" to allow passing of internal representation and the according TclObj * * c-implemented methods: report types in "info parameter" for more builtin types. * use "-withObj" in mongodb interface * adapted regression test - mongodb interface: * mongo::gridfile::seek: added a seek command for gridfiles * added example for the low-level interface to shwo how to access gridfs via the plain mongodb interface, how to add some additional metadata (e.g. dublin core meta data) and how to retrieve this via the gridfile interface - nsf.c: * report only fully initialized slot objects via "info slots" to avoid chicken-egg problem during method "objectparameter" * added flag -array to ::nsf::var::exists to check, whether the variable is an array (to avoid "o eval {array exists ...}" in the serializer. * provided flags to VarExists instead of multiple args * don't add new pointer entries in Nsf_PointerTypeLookup() - preliminary fix for volatile called through residual args - new regression test file volatile.test - fix the comparison with "unknown" in residual args - provide backward compatibility for unknown method (when method contains spaces). - some minor cleanup - extended regression test - fix typos in string "unknown" (unknwon, unkown) - reduce verbosity - reduce scope of variables - renamed ObjectParameterSlot attribute from nosetter => accessor (positive formulation) - nsf.c: make sure to always initialize variables - first draft of separation of attribute -> variable + accessor - library/mongodb: * updated to current interface in git HEAD * added flag timeout to mongo::connect * added new index options "-sparse" and "-background" - regularized more nsf::* names: renamed "nsf::createobjectsystem" => "nsf::objectsystem::create" renamed "nsf::unknown" => "nsf::object::unknown" renamed "nsf::dispatch" => "nsf::object::dispatch" - generalized "nsf::object::initialized" to nsf::object::property objectName initialized|class|rootmetaclass|rootclass|slotcontainer - nx: factor out method createFromParameterSpec - method variable: * check default value * added shortcut, when no slot object is needed * extended regression test - nx::Attribute: changed method 'checkInstVar' to 'setCheckedInstVar' -

fixed a possible crash in the ExitHandler: Object create o {exit -1} - nsf.c: * added flag "-array" to nsf::var::set such we have now "::nsf::var::set ?-array? object varName ?value?" With "-array", nsf::var::set behaves like "array get" or "array set" (on instance variables) * use "::nsf::var::set -array" in serializer symmetrically to scalar case * extended regression test - nsf.c: * fixing compilation with NSF_MEM_COUNT * New function DeleteProcsAndVars() to trigger deletion of ParamDefs (fixes a small memory leak); * improved comments * improved INCR_REF_COUNT/DECR_REF_COUNT for easier tracking of potential refcount errors * added macros DECR_REF_COUNT2() and INCR_REF_COUNT2() for easing the association of refcounts to locations in the code by providing names for refcounts. * fixed a refcount bug for valueObjs in non-NRE-enabled versions in the argument vector of scripted methods (found via INCR_REF_COUNT2/DECR_REF_COUNT2) - nsf.c: * refined refcounting debugging * fixed various refcounting bugs, especially in error cases. * added explicit INCR_REF_COUNTs on Tcl_Objs with 0-refCount to ease debugging * added explicit names for refcounting for "paramDefsObj" * added explicit names for refcounting for "freeList" (for forwaders) * provide debug-refcounts for "NSNamespace" * provide debug-refcounts for "nextArgumentVector" nsf.c: * change DeleteProcsAndVars, such it deletes procs and vars explicitely in all namespaces * added more sanity checks for parameterContexts, testing in ParseContextRelease() in DEBUG mode * provide debug-refcounts for "pcPtr.objv" * provide debug-refcounts for "pcPtr.clientData" nsf.c: * provide debug-refcounts for "class.activationCount" * provide debug-refcounts for "object.activationCount" * deactivated CHECK_ACTIVATION_COUNTS oer default * tested refcounts with Tcl 8.6b2, found bug in Tcl and submitted patch to sourceforge http://sourceforge.net/tracker/?func=detail&aid=3383616&group_id=10894&atid=110894 - nsf.c: * fixed a bug in "info parameter list|... name" when the named parameter is not found (returns now empty, before, it was returing the full list). * added flag "-nocomplain" to nsf::var::unset - nx.tcl * added "delete variable" analogous to "delete attribute" * unset instance variable for object-level "delete attribute" * extended regression test - library/mongodb: * updated to current interface in git HEAD (resp. "git checkout v0.4") - nx.tcl: * fixed copy for object created with new * copy returns now the fully qualified name of the copied object * extended regression test - library/mongodb:updated to current interface in git HEAD - nx.tcl: implemented copy without a provided name. If argument of copy is omitted, the copied object is created with a fresh name (i.e. created with the method "new"). Example set x [o copy] - extended regression test - nx.tcl: * added protected and public for "require method" The following forms are now valid "... require public method" "... require protected method" "... require method" "... require public class method" "... require protected class method" "... require class method" * extended regression test - library/mongodb: * replaced NsfMongoGetHostPort() with the newly available function mongo_parse_host() * updated error codes according to git head * factored out mapping of error code to string - nsf.c: added cmd __db_compile_epoch for compile-epoch introspection - Mystery solved, why in the script below the interp>compileEpoch is incremented, when D is redefined, but in other cases not. In the script below the method D.init is compiled by tcl, since it has a trivial body. Therefore, a redefinition of D will remove this compiled body and all its potential usages. Therefore the interp->epoch is incremented. If the body is e.g. "return", the epoch is not incremented (observed with Tcl 8.5.10) ================================================= # -*- Tcl -*- package require XOTcl; namespace import -force ::xotcl::* package require nx::test; namespace import nx::Test Class C; C c Class D -superclass C D instproc init args {} Test new \ -count 100 \ -pre { puts stderr ===create-D;Class create D; puts stderr ===D-created; Class E; Class E1; Class X -instmixin {D E E1}} \ -cmd {X info instmixin ::E*} \ -expected {::E ::E1} \ -post {foreach o {D E E1 X} {$o destroy}} Test new \ -count 100 \ -pre {Class D; Class E; Class X -instmixin {D E}} \ -cmd {X info instmixin ::E*} \ -expected {::E} \ -post {foreach o {D E X} {$o destroy}} Test run; exit ================================================= - nsf.c: * enabled MEM_COUNT debugging for multi-threaded apps. We collect the MEM_COUNT statistics now per interp.

Version is now 2.0a1 Warning: From the Tcl point of view, this is a regression in numbering relative to the previous 2.0.0. Make sure to remove old releases from you installation path like e.g. rm -rf /usr/local/lib/libnsf2.0.0* /usr/local/lib/nsf2.0.0 - use same version numbers in nsf, nx and xotcl2 - library/lib/nx-zip.tcl: refactored implementqtion, improved utf-8 file-name handling (which is a mess in pkzip) - configure options: * improved and extended configure options to reduce necessity to switch features on and off in the nsf.h. Optional Features: --enable-profile build nsf with profile support (default disabled) --enable-memcount=yes|trace build nsf with memcount debug support (default disabled) --enable-development build nsf with development support (assertion checking, etc.; default disabled) Optional Packages: --with-dtrace build nsf with DTrace (default: without) - nsf.c: * report configuration options via "parray nsf::config" sample output % parray nsf::config nsf::config(development) = 1 nsf::config(dtrace) = 0 nsf::config(memcount) = 0 nsf::config(memtrace) = 0 nsf::config(profile) = 0 - build-environment: * make configure.in Makefile.in more in line with the TEA sample app (removing leftovers from prior versions of TEA) * remove GNU-Makefile-isms from Makefile.in - nsf.c: * provide an intermediary fix for the final memcount problem of elements in on the iPtr->errorStack * improve iPtr cleanup for memcount debugging - added configure option: enable-assertions (default on) - nsf.c: * allowed to call ":" like "my" or "self" Object create o o public method bar2 {} {return bar2-[: foo]} o public method bar5 {} {return [self]::bar5} o public method bar6 {} {return [:]::bar6} * extended regression test - nx.tcl: moved "properties" from nx::Class to nx::Object - nsf.c: make ":" a full equivalent vor nsf::my (i.e. support -local, -system and -intrinsic) - extend regression test nsf.c: - reform of argument parse. new parser uses NsfFlagObjType to reuse earlier parse results. Improved speed for for methods with primitive bodies: 5%-25%. - added regression tests for argument parsing - nsf.c - added experimental parameter option noleadingdash - additional regression test file method-parameter.test - provide selective error messages for unknown nonpos args nsf.c: - reform of method lookup. new code uses NsfInstanceMethodObjType and NsfObjectMethodObjType to reuse earlier lookup results. Improved speed for for methods with primitive bodies (over version before argument parse reform: 10%-43%. - additional compile-time option: METHOD_OBJECT_TRACE - experimentation version of unknown handler for non-pos args - extending regression test nsf.c: - moved methodEpochCounters from global vars to the interp state to improve reuse in multi threaded apps - separated objectMethodEpoch and instanceMethodEpoch - bump version number to 2.0a2 nsf.c: - new cmd for debugging: nsf::__db_show_obj - added MethodDupInternalRep() and FlagDupInternalRep() since they appear to be required in Tcl 8.6b2. tests: - added "package prefer latest" to avoid confusions of alpha and beta releases with install versions nsf.c: - added MixinregDupInternalRep() and FilterregDupInternalRep - perform more eager invalidation on objectMethodEpochs - cleanup on nsfObj.c nsf.c: - don't convert obj types tclCmdName and parsedVarNameType to instanceMethodObjType nx: added traits package nonleadingdash handling: - doc: added "nonleadingdash" to UML class diagram - nsf.c: added error message, when "noleadingdash" is used on non-positional parameters - nsf.c: use same logic for "nonleadingdash" to "value in argument" - nsf.c: deactivated rudimentary unknown handler non nonpos args for the time being - nx.tcl: added handling of parameter option "noleadingdash" in objectParameterSlots - doc: * integrated ::nx::doc::make with Makefile.in (provide shell calls and, targets and dependencies) * provided a different flag for the generation of the documentation (-develop, .... or -final) to show/hide it. * separated entries for methods and hooks (can't be called if not defined)? hooks: * recreate should only be called internally, similarly "init" etc. * __unknown unknown is a hook for Object but a method for Class - fixed strange ref-counting bug in 8.6b2 bug-is-86.tcl where 2 ref-counted items are not freed (value:class, issued from nx.tcl around line 120). Compile with DEBUG86B2 for more info ================================================= # -*- Tcl -*- package req nx package require nx::test nx::Test case ensemble-next-with-colon-prefix { nx::Object create obj { :public method foo {} { return [:info class] } #:public method bar {} { return [:info] } :method info {} {;} } ? {obj foo} {wrong # args: should be ":info"} } ================================================= - nsf.c: cleanup on DEBUG86B2 - nx.tcl: * do not namespace import my into ::nx * replace usages of "my" by colon invocations - doc: * extended method resolution section * documented invocation flags for colon - nsf.c: * add flags "-closure" and "-source" to "/cls/ info methods" (the cases for "/obj/ info methods" are already covered by "/obj/ info lookup methods") * extend regression test - nx-traits: * use "info methods -closure" instead of instantiating a class at trait-insertion time * added trait as package nx::callback - example scripts: added tk-mini and tk-horse-race - make "/object/ require" an ensemble method - traits: renamed "useTrait" into "require trait" - added per-object traits (and per-class-object traits) - added tk-spread and tk-locomotive to example scripts - altered default handling to honor side effects of aliased object parameters. This slows down evaluation a little. Side-effects from aliased parameters are discouraged, since the order of the evaluation should not matter of an declarative evaluation of the argument vector. - extended regression test - library/mongo: * updated interface to current nx * updated to mongo-c-driver 0.4 (current version) * The mongo c-driver does not allow to add DBRefs, since it refuses to accept field names with leading '$'. So we skip these tests for the time being. -nsf.c: - remove quadratic behavior when adding many classes (10 thousands) - deletion is still for huge number of classes quite slow. - nx.tcl, xotcl.tcl: * remove proc "register_system_slots" since 'rename register_system_slots ""' fails on aolserver * bump version number to 2.0b1 - nsf.c: extended "new": * nonpos-arg "-childof" accepts now a namespace (required an object before). Therefore, one can use now "... new -childof [namespace current]", even when the current namespace is not an object - nx.tcl: simplified ::nx::ScopedNew to ::nx::NsScopedNew: before it was necessary to create a new volatile class for every invocation of contains. - extended regression test - nx.tcl: don't use mixins in method "contains", but remap the new implementation. If there are ten thousands of classes defined, adding mixins to the root meta-class degrades linearly on the number of classes defined (the mixin paths for all classes must be invalidated). This might be a problem for frequent "contains" invocations. - bump version numbers for nx, xotcl2 and nsf to 2.0b2 - rename "info method handle /methodName/" into "info method registrationhandle /methodName/" - rename "info method origin /methodName/" into "info method definitionhandle /methodName/" - added "info method handle" as short form of "info method definitionhandle" - added "info method origin" to return the target of an alias (or empty) - update migration guide and tutorial - cleanup "//" in sources nsf.c: - adding method epoch incr to NsfAddObjectMethod() and NsfAddClassMethod() - added function CmdListAddSorted() to improve mixinof management serializer.tcl: - Use directdispatch to query existing traces without the need of an extra method. By this change, the serializer works in constant time independent on the number of existing objects. nsf.c: - reduce number of RUNTIME_STATE(interp) in favor of a variable. - make time of the definition of a method independent on the number of defined instances (unless, when filters are defined) nsf.c: - fixed bug with recursive aliases - extended regression test - updated and shorted README.aol and TODO - removed the following files from the repository. deleted: COMPILE deleted: COMPILE.win deleted: ChangeLog deleted: unix/xotcl.spec.in deleted: win/Makefile.vc These files should be probably added again at some later time, but need some rework. Old versions are still available from the 2.0.0-develop branch - Replaced hash-table for GetAllInstances() with a linear list. As a result, mass-destroy on exit is now much faster. Valgrind reports that the full circle of creating 100.000 objects and destroying it on exit became about 15% faster. - added additional argument adEnd to CmdListAdd() - renamed CmdListRemoveList() to CmdListFree() - improved code documentation - removed unneeded AddInstance() and RemoveInstance() - deactivated uncalled ReverseLookupCmdFromCmdTable() and GetHiddenObjectFromCmd() since apparently not needed any more nsf.c: - removed conditionals in AddInstance() and RemoveInstance() - dropped result from RemoveInstance() nsf.c: - added method NsfMethodNamePath() to compute the ensemble path in error messages - reduce verbosity - extended regression test - nsf.c: fix call of DispatchDefaultMethod() in cases it triggers an error for 8.6b - nx.tcl: give a slightly better error message in case the root-object of an ensemble is called directly nsf.c: - handle duplicates in the cmd-list during cleanup - Avoid duplicate entries in instance lists for diamond inheritance by maintaining the set of already processed entries in NsfClassInfoInstancesMethod1() and GetAllInstances(). - extended regression test - removed "namespace import" in object-system test nsf.c: - Reform of subclass/superclass handling. * unifying transitive subclass handling * localizing and documenting caching of subclass/superclass lists * eliminating repetitious computation of subclass lists * re-factored code, renamed some functions to better reflect their purpose * improved documentation - fixed a potential crash for class deletion triggering implicit deletions further deletions referencing the parent class - extended regression test nsf.c, nsf.h, nsfStack.c, nx.tcl, tcl-cool.tcl, xotcl2.tcl - fix spelling in comments - strip unneeded space - fixed potential crash when generating error message about argument usage when called without a callstack - added regression test nsf.c: - change argument of IsMetaClass() to type *NsfObject - provide basic protection against most likely unintended deletion/overwriting of base classes. - extend regression test - fix typos - extend regression test to improve coverage - improve branch prediction - simplify macro handling with __WIN32__ - regroup some macro definitions - "info method": missing an option to return the "-returns specification". Also: "-returns" spec is not included in "info method definition". - simplified usage of ObjectName() and ClassName() macros (no caller parenthesis needed) - added experimental object property keepcallerself (currently only evaluated by aliased objects) - removed TODOs from keepcallerself in destroy.test; calls were truly recursive, behavior was correct. - Added experimental object property "allowmethoddispatch" for child-objects to be called from parent objects via method interface. Background: both, per-object methods and childobjects are implemented via cmds in the same tcl namespace. Without special care, both are callable via the standard dispatch. Apparently, this is not always wanted. - handled allowmethoddispatch and keepcallerself in copy/move - set allowmethoddispatch per-default in XOTcl - removed visibility of objects with "allowmethoddispatch" false in "info methods" and "info search methods" - extended regression test - improve handling of multiple error messages in a single command - alias reform: instead of calling first an alias with a stack frame followed by the dispatched of the aliased cmd, resolve aliases internally in dispatch. This has the advantage that we do not have to ignore the "transparent" stack frame in some situations, and we have much less problems with the names of the aliased cmds (e.g. objects) in the introspection methods. Additionally, several problem cases disappeared from the regression test cases. In addition, the new approach is faster. - eliminating obsolete flag NSF_CSC_CALL_IS_TRANSPARENT - use alias-stubs for aliases pointing to objects. This allows us to distinguish between cases, where an object is dispatch-able due to the alias or due to allowmethoddispatch (when the object happens to be a subobject and has therefore its cmd in the same namespace). The semantics are now: - aliases to objects are always dispatch-able, no matter, how allowmethoddispatch is set. - direct sub-objects of objects are currently on dispatch-able when allowmethoddispatch is set. Note, that this could be seen as a method-property of the method-name, which could be made "private" as well to avoid such direct dispatches. - nsf.c: start all error messages with a lower case word for consistency and to follow closer to Tcl's conventions - deactivate for the time being allowmethoddispatch (make it behave always like true) - added instead new flag "perobjectdispatch" to make behavior of ensemble objects configurable. - The behavior for keepcallerself is currently only activated for the method-interface for object dispatch, since otherwise the following would be dangerous, since "o2 foo" would destroy o2 nx::Object create o1 nsf::object::property o1 keepcallerself true nx::Object create o2 { ::public method foo {} {o1 destroy} } o2 foo - fixed potential crash from method caching, when permissions on cmds are changed and become e.g. unresolvable - removed flag allowmethoddispatch, since behavior can be archived via private flag. - extended regression test - extend regression test for interactions between "keepcallerself" and "perobjectdispatch" - some minor cleanup - fixed NRE memory management (for Tcl 8.6) by refactoring alias handling - removed documentation about incompatibility to XOTcl1 in respect of the method interface for object invocations - doc fixed line-number handling locally - changed object->flags from "unsigned short" to "unsigned int" - reintroduced NSF_TCL_DELETE to address bug flagged from memdebug - extended regression test - Cleanup for compilation under MSC (avoid unsupported forward declaration of array) - further documentation of functions, better grouping of functions - use fixed array size for method_definitions for MSC - Don't export symbols in the general case just because of MSC/C89 compliance - Forward setting of object parameters to the slot object, when assign method is user-defined on the slot object - Cleanup and extend regression test - additional object parameter option "invokesetter" managed by nx.tcl This was necessary, since the previously implemented strategy called the setter whenever slot= was provided. This has the problem, that values could be converted twice (once by "configure", once by the setter method", which lead for the converter to a double refcounting on the value. - use Tcl's EXTERN macro instead of "extern" - treating incompatible forwarding to slot vs. slot option noaccessor - extended regression test - don't allow object creation to overwrite non-object cmds (e.g. procs) - don't allow method to overwrite child object - extended regression test - documented cmd overwrite protection feature as incompatibility with XOTcl 1 - documented dependencies between configure flags and feature activation cpp macros nsf.c: - Fixed a bad interaction between Tcl's apply (pushing lambda frames) and the variable resolvers. The variable resolver was not able to resolve variables, while the command resolver was still working correctly. - Extended regression test nsf.c: - added object parameter option "slotinitialize" - renamed object parameter option "invokesetter" -> "slotassign" - call slot.assign instead of setter of object - removed restriction on nosetter/invokesetter: nosetter can be used in connection with slotassign - added regression test for slot.initialize nsf.c: - pass property name to slot "initialize" method to conform with the interface to "assign", "get" ... (all these receive the property name as well) - allow slot "initialize" method to be protected (handled similarly to "init") - extended regression tests for yield - implemented "next" for ruby-like enumerators (each needs still more work) - tcl86.test: better implementation of method "each", cleanup and extension of enumerator tests - fix compilation when compiled without threads (many thanks for r.zaumseil for noting this). - protect serial generation for parameters via mutex - added compile macro NSF_STACKCHECK to provide stack monitoring/debugging (especially useful for multi threaded programs, where stack is more limited) - make ::nsf::log more robust for aolserver/naviserver, since ::ns_log is not always around when an output is needed - serializer: * make [::Serializer deepSerialize -ignoreVarsRE "" $o] behave like [::Serializer deepSerialize $o], since learn@wu depends on that, and a value for ignoreVarsRE of empty looks more like an omitted value than a regular expression, that should match everything. * extended regression test nsf.c: - generalize stack monitor by handling growing and shrinking stacks - refactor into funciton CheckCStack() - serializer: * pertain perobjectdispatch and keepcallerself in serializer * extend regression test nsf.c: - refactor ObjectCmdMethodDispatch() for clarity - prepare work on object method dispatches with KEEP_CALLER_SELF and no NSF_PER_OBJECT_DISPATCH - explorative implementation of object method dispatches with KEEP_CALLER_SELF and no NSF_PER_OBJECT_DISPATCH - extend regression test nsf.c: - implement escaping for comma in value of parameter options: escaping in values can be achived via duplicating the comma. In the following example is the value for arg "1,3" D public method foo {a:commaRange,arg=1,,3,optional} {..} Escaping via \ whould actually require 4 backslashes due to Tcl's escaping rules (two, to get a single backslash, another two due to list-splitting to obtain default from arg). - extend regression test nsf.c: - allow parens in property names (array syntax) - added "/obj/ info name" (as alternative to "namspace tail [self]") nx.tcl: - added "private property foo" - extended regression test - start error messages with a lower case word for consistency and to follow closer to Tcl's conventions Documentation: - added design study ruby-mixins.tcl to example-docs and regression test - added documentation for "/obj/ info name" to migration guide and .nxd file - adding more comments to examples in migration guide - document private properties in tutorial and migration guide - improve wording in documenting - extend regression test nsfShadow.c - bump MethodEpoch when a tcl ::rename command happens on a nsf method (which might be cached in a Tcl_Obj) This fixes a crash reported by Arthur Schreiber nsf.c: - make NsfInstanceMethodEpochIncr() and NsfObjectMethodEpochIncr() accessible from all files using nsfInt.h - remove experimental code (backslash escaping for "," in parameter option parse nsf.c: - added a SlotContainerCmdResolver() to avoid interaction of slot names with names of callable tcl commands. Without the SlotContainerCmdResolver() the call to "list" in a property named "list" leads to a call to the container object ::Test2::slot::list instead to the intended ::list. The implementation is not perfect, since it ignores the namespace path inside the slot container. - added regression test. nsf.c: - ignore in internall calls to "dealloc" protection settings - handle cyclical class dependencies during object system finalize - extend regression test nsf.c: - handle cyclical superclassclass dependencies during object system finalize - extend regression test nx.tcl: - set multiplicty for mixins and filters by default from 1..n to 0..n to avoid error messages, when e.g. empty mixin lists are configured. Setting emtpy mixin-lists is strictly speaking not necessary, but this eases the code in cases the lists are sometimes empty. nx::test: - added summary at the end of "make test" via log file - updated .gitignore nsf.c - rename nx::Object.configure to nx::Object.__configure to free method name "configure" for an e.g. tk-like configure - refactored code to allow to parameterize handling of required flag for parameters - don't flag an error when configure is called on an initialized object (logic: if the object is initialized, configure must have been called before, and the required action must have been already taken). nx.tcl: - rename the following internally called methods (not for XOTcl). alloc -> __alloc dealloc -> __dealloc objectparameter -> __objectparameter recrate -> __recreate - from these methods, only __objectparameter is defined per default, the others are defined on demand - updated 34 copyright notices nsf.c: - extended nsf::method::delete to handle ensemble names nx.tcl: - added tk/incr-tcl style cget methods on class/object levels as ensemble methods. - improve copy handling with other child-types of the slot container working - make sure to ignore non-slot-type objects in slot introspection - worked on regression test until "methods.test". others are missing, but maybe reconsideration nsf.c: - implememted cget as a configure-like method, dropped ensemble method variant nx.tcl: - simplified "/obj|cls/ delete method" due to resolving capabilities in nsf::delete::method xotcl2.tcl: - made destructor of Connection more robust such it does not depend on accessor methods. - fixed regression test to run all test again correctly nsf.c: - made argument of cget required nx.tcl: - added Tk-style methods "configure" and "cget" - added additional regression test set for cget and configure - renamed testlog file, remove it on "make clean" nx.tcl: - remove debugging output nsf.c: - fixed parmeter syntax for required nonpos args - deactivate deletion of methods via nsf::object::delete during shutdown to avoid missing slot forwarders called from destructors nx::Class create C { :property {b b1} :public property {c c1} :protected property -accessor {d d1} :variable foo } Property reform part 1: - disallow protection modifiers for "properties" and add new flag "-accessor" to "property" and "variable" This changes definitions like Class create C { :property {a a1} :public property {b b1} :protected property {c c1} :private property {d d1} } to Class create C { :property {a a1} :property -accessor public {b b1} :property -accessor protected {c c1} :property -accessor private {d d1} } since "properties" are always public accessible over the "configure" and "cget" interface, but the accessors methods might not be public. The value of the accessor might be also "none" (specifying explicitely that no accessor is wanted) or "", which means: use the default. Same holds for "variable" - disallow parameter option "incremental" and change it to a flag of the property or variable. The motivation for this is due to the fact, that "incremental" is a property of the accessor, and not of the value. old: Class create C { :property foo:int,incremental :variable bar:int,incremental } new: Class create C { :property -incremental foo:int :variable -incremental bar:int } - disallow "public class property" and friends since these are not needed - removed parameter property "noaccessor" - removed "nx::configure defaultPropertyCallProtection" and method hook "__default_property_call_protection" - introduced "nx::configure defaultAccessor" and method hook "__default_accessor" - for the time being, "defaultAccessor" is "public" for NX and XOTcl, will be changed to "none" in NX - extended regression test (new file properties.test) Property Reform Part 2: better handling of per-object properties nsf.c: - changed "/class/ __objectconfigure" to "/obj/ __objectconfigure" to be able to handle per-object properties on classes properly. - renamed "info method parametersyntax" -> "info method syntax" - renamed "/obj|cls/ info method parametersyntax" into "/obj|cls/ info method syntax" - replaced "::nsf::methods::class::info::objectparameter" by "::nsf::methods::object::info::objectparameter" - new command "::nsf::parameter::specs ?-configure? ?-noposargs? slotobjs": convert provided slotobjs into a list of parameter specs - new command "::nsf::parameter::get list|name|syntax parameterspec": convert parameter spec into syntax form, or retrieve pieces of information from it (can be extended in the future) - added more or less generic list handling functions TclObjListFreeList(), TclObjListNewElement() and TclObjListAdd() used by "::nsf::parameter::specs" - replaced "::nsf::method::property /obj/ -per-object /name/ slotcontainer ?value?" by "::nsf::object::property /obj/ slotcontainer ?value?" - added "::nsf::object::property /obj/ hasperobjectslots ?value?" nx.tcl: - new info methods * "/obj/ info lookup parameter definitions" * "/obj/ info lookup parameter names" * "/obj/ info lookup parameter list" * "/obj/ info lookup parameter syntax" - changed "/cls/ info parameter definition ?name?" into "/cls/ info parameter definitions ?name?" since ir returns a list. Still, "list" or "syntax" won't be plural XOTcl 2 - don't blindly register all object/class methods for XOTcl nsf.c: - fix potential bad interaction between per-object mixins and per-class caching of object-parameters - first draft of per-object parameter caching (for per-object-mixins and per-object properties). nsf.c: - rename invalidateobjectparameter -> parameter:invalidate::classcache - rename invalidateobjobjectparameter -> parameter:invalidate::objectcache - bring cmds into alphabetical order - NsfObjInfoObjectparameterMethod(): return not only the first matching parameter, but the list of all matching ones. The last optional argument was renamed from "name" to "pattern" accordingly - invalidation of per-object parameter cache * on mixin changes and * on deletion/adding of per-object slots - activate PER_OBJECT_PARAMETER_CACHING per default (flipping this parameter makes regression test more than 20 faster). - extended regression test nsf.c - added functionality for "cget" to call parameter-methods (e.g. "... cget -class"). The method cget calls either "/slot/ get ..." (when slot=... is provided in the parameter spec) or it assumes that the method without argument returns the value - added "::nsf::object::property /obj/ volatile" to query whether a object is volatile or not - "/obj/ cget -volatile" returns now the volatile state of the object - factored out ParameterMethodDispatch() from OConfigureMethod() - extended regression test nx.tcl: - change parameter name in "/cls/ info parameter ... ?pattern?" from "name" to "pattern" - changed name "/obj|cls/ slot info definition" to "/obj|cls/ slot info definition" since result is a set - dropped parameter method "properties" - dropped "/obj/ info properties" (since "properties" or "variables" are returned") - extended regression test nsf.c: - factored out ParameterMethodForwardDispatch() to call a parameter method defined as a forwarder the same way from "configure" and "cget" - extended regression test nx.tcl: - property has now a boolean non-positional argument "-config" /obj|cls/ property ?-accessor value? ?-config boolean? ?-incremental? ?-class value? spec ?initblock? in symmetry with "-accessor" (parameter option "noconfig" is still needed to flag nsf for variables that should be initialized, which are not configurable - "/obj|cls/ info slot definitions" returns a full command (containing flags and property|variable) - extended regression test nsf.c: - handling of method names in error messages from nsfAPI.h. Make sure that error message is generated with the actual method name. Object-method Reform: - changed interface to object specific commands by requiring an ensemble named "object". The rational behind is essentially to use always the same info command to retrieve object specific methods, no matter whether these are defined on a plain object or an a class object (does not break the "contract" what e.g. "info method" returns). Now we define methods via: /cls/ method foo {args} {...body...} /cls/ object method foo {args} {...body...} /obj/ object method foo {args} {...body...} Similarly, aliases, forwards and mixins are defined, e.g. /cls/ mixin add ... /cls/ object mixin add ... /obj/ object mixin add ... /obj/ require object method ... /obj/ object property ... /obj/ object variable ... The same change propagated as well to the "info" method. Now we have: /cls/ info methods ... /cls/ info object methods ... /obj/ info object methods ... Similar, the object parametererization uses /cls/ create obj -object-mixin M /cls/ create obj -object-filter f /metacls/ create cls -mixin M1 -object-mixin M2 /metacls/ create cls -filter f1 -object-filter f2 - as a consequence, a) "/cls/ class method ..." "/cls/ class alias ..." "/cls/ class forward ..." "/cls/ class filter ..." "/cls/ class filterguard ..." "/cls/ class mixin ..." "/cls/ class mixinguard ..." "/cls/ class info ..." "/obj/ class method require method ..." "/obj/ class method require public method ..." "/obj/ class method require protected method ..." "/obj/ class method require private method ..." "/cls/ class property ..." "/cls/ class variable ..." "/cls/ class delete property ..." "/cls/ class delete variable ..." "/cls/ class delete method ..." "/cls/ require class method ..." "/cls/ require public class method ..." "/cls/ require protected class method ..." "/cls/ require private class method ..." were dropped b) "/obj/ method ...." "/obj/ alias ...." "/obj/ forward ...." "/obj/ filter ...." "/obj/ mixin ...." "/obj/ info method*" "/cls/ create obj -mixin M" "/cls/ create obj -filter f" "/obj/ require method ..." "/obj/ require public method ..." "/obj/ require protected method ..." "/obj/ require private method ..." were dropped - added package nx::class-method to allow optionally the "class" notation "/cls/ class method ..." (and friends, see (a)), and "/cls/ class info ... - added package nx::plain-object-method to allow optionally plain method b) "/obj/ method ...." (and friends, see (b)) - added support to slots to use ensemble methods as setters - added "/obj/ object variable" and "/obj/ object property" - bumped version number to 2.0b5 - tested with NaviServer and OpenACS (new version of nx needs as well a newest NaviServer, since ns_cache implementation needs to be objectified; newest NaviServer version works as well with older nx) - moved "/obj/ info slot definition|..." to "/obj/ info object slot definition|..." for consistency - provided "parametersyntax()" for "object mixin" and "object filter" Method and configure parameter reform: - unify handling / naming / parameterization of method parameters and configure parameters - New Interface: /cls/ info configure parameters ?pattern? -> list of params /cls/ info configure syntax -> syntax output /obj/ info method parameters /methodName/ ?/pattern/? -> list of params /obj/ info method syntax -> syntax output /obj/ info lookup configure parameters ?/pattern/? -> list of params /obj/ info lookup configure syntax -> syntax output /cls/ info parameter list|name|syntax /param/ -> value "... method syntax" and "... configure syntax" return the full method/configure call, and not only the parameters as in previous versions. Therefore, providing a pattern could lead to unexpected results, therefore the argument was dropped. - Replacements relative to 2.0b4: {/cls/ info parameter definitions} -> {/cls/ info configure parameters} {/cls/ info parameter definitions x} -> {/cls/ info configure parameters x} {/cls/ info parameter syntax ?pattern?} -> {/cls/ info configure syntax} {/obj/ info lookup parameter definitions ?pattern?} -> {/obj/ info lookup configure parameters ?pattern?} {/obj/ info lookup parameter syntax ?pattern?} -> {/obj/ info lookup configure syntax} - Dropped calls: /cls/ info parameter list ?/pattern/? /cls/ info parameter names ?/pattern/? syntax of a single parameter via this interface /cls/ info configure syntax ?/pattern/? /obj/ info lookup parameter names ?/pattern/? /obj/ info lookup parameter list ?/pattern/? Method and configure parameter reform, Part 2: In order to streamline the interface further, we tried to follow the idea to use "... info /plural word/" to obtain a set of handles, and then a separate call to obtain the details. Therefore, we replaced /cls/ info slot objects /cls/ info slot definitions /cls/ info slot names /obj/ info object slot objects /obj/ info object slot definitions /obj/ info object slot names /obj/ info lookup slots by /cls/ info slots ?-type /type/? ?-closure? ?-source all|application|baseclasses? ?/pattern/? /obj/ info object slots ?-type /type/? ?/pattern/? /obj/ info lookup slots ?-type /type/? ?-source all|application|baseclasses? ?/pattern/? - nx.tcl: handle "incremental" in slot reconfigure - nx.tcl: change defaultAccessor to "none" - dropped "/obj/ info slot definition /slotobj/" in favor of "/slotobj/ definition" Method and configure parameter reform, Part 3: - added /obj/ info lookup variables -> list of handles /obj/ info lookup object variables -> list of handles /obj/ info variable definition|name|parameter /handle/ - nx.tcl: added forward compatible scripted implementation of "lmap" - nsf.c: handle names for private slots in pattern provided to AddSlotObjects(), used e.g. in "info lookup slots /pattern/" - added new regression test info-variables.test - nx-pp.tcl: fixed changed accessor handling, added cget to highlight words - updated next-migration guide to reflect changes from the configure reform - "info method syntax" returns now "/cls/ ...." - "info object method syntax" returns now "/obj/ ...." - hopefully the last changes for ?object? method|variable|property: defined * "/obj/ delete object method" * "/obj/ delete object property" * "/obj/ delete object variable" - extended parameter extractor: new functionality ::nsf::parameter get default /parameter/ ?/varname/? ::nsf::parameter get type /parameter/ /obj/ info parameter get default /parameter/ ?/varname/? /obj/ info parameter get type /parameter/ - nsf.c: handle full-qualified name for private slots (AddSlotObjects()) - extended regression test - C-code Generator: added "-typeName" for enumeration types that allows for disambiguation of enumerations with different argument names. Before that, the argument name determined the c-type of the enumeration. Therefore it was not possible to use argName "-type" for two different functions with a different list of enumerators. - changed "-methodtype" to simply "-type" in /obj/ info methods ... ?-type all|scripted|builtin|alias|forwarder|object|setter|nsfproc? ... /obj/ info object methods ... ?-type all|scripted|builtin|alias|forwarder|object|setter|nsfproc? ... /obj/ info lookup methods ... ?-type all|scripted|builtin|alias|forwarder|object|setter|nsfproc? ... - removed some TODOs from tests/parameters.test - parameter dispositions: We differentiate now between "initcmd" and "cmd": an "initcmd" is only evaluated once, but one can provide configure values for this parameter later. a "cmd" is executed on every evaluation, it is only possible to pass cmds to it. The trailing argument of the configure parameters (used e.g. for scripted object/class definitions) is now of type "cmd". Implementation not yet complete (object cases are not correct). - nsf.c: fix crash when "nsf::my" is called with a single argument outside the object context. - fixed cases, where valuechangedcmd (and the other traces) did not work with "configure" method. When slot traces are used, it cleans other traces for the same operations. - extended regression test - added implementation for slots with traces+types for classes - exception for incorrect defaults are thrown during slot creation - extended nsf::is, added parameter * ?-configure? -- accept configure parameter options * ?-name /name/? -- provide a parameter name for error message - simplified nx.tcl by using new nsf::is - extended regression test - changed ::nsf::parametersyntax(..) to ::nsf::parameter::syntax(..) - xotcl2: adjusted manual parameter syntax entries to new conventions Cleanup of nsfAPI.decls - remove unneeded enumeration types - use "typeName" to shorten reported names of parameters - use camel case for reported names Traits: - changed from traits-as-objects to traits-as-classes. This allows for higher orthogonality of traits and class definitions and allows in principle traits for object-specific methods (not fully implemented/tested) - fixed property/variable inheritance in traits. nsf.c: - changed enumeration values for "-source" in "info lookup methods" "info lookup slots" "info methods" "info slots" of "all|application|baseclasses" to "all|application|system" for consistency with "nsf::my" and "nsf::dispatch" which uses "-system" as well nx.tcl: - removed "info is .." since it might raise more questions than it solves - renamed initblock parameter from __initcmd to __initblock - renamed nsf::configure parameter from "keepinitcmds" to "keepcmds" - saving "keepcmds" in an associative array named "__cmd(/parameternName)" to allow saving of multiple parmeters with less name clash danger (when application stays away from variables stating with double underscore) - completed coverage if plain-object-method.tcl - provided warnings via plain-object-method.tcl via "nsf::log warn ..." nsf.c - fixed potential infinite loop in pattern matching for precedence lists - cget: make error message closer to tcl conventions - extended regression test package nx::plain-object-method: - made warnings configurable via nx::configure plain-object-method-warning on|off - completed coverage and test cases package nx::class-method: - convenience package similar to nx::plain-object-method - allow for usage "C class method ..." in addition to "C object method". - made warnings configurable via nx::configure class-method-warning on|off - completed coverage and test cases nx.tcl: - replaced functionality of "/obj/ configure" by "/obj/ info configure" to re-enable semantics of the plain configure method, even when called without arguments. "/obj/ info configure" is actually a convenience method to allow to write o1 info configure instead of o1 info lookup configure syntax - traits: added ability to turn on verbosity for traits by using nx::configure trait-verbosity on|off nx.tcl: - renamed variable option "-config" to "-configurable" to make its intention clearer - changed multiplicity of mixin, object-mixin, filter, object-filter from 1..n to 0..n; rationale: when one has a list of eg. mixins, which should be passed, one has to test for the length before passing it, otherwise the empty list would generate an error. Allowing 0..n makes the usage simpler and the program shorter. Removed oboslete item. At least in this concrete form, the warning does not show up. - NSF_WITH_VALUE_WARNINGS: Right now, value warnings are also fired for arg vectors with a delimiting "--"; right now, this gives a warning: Object create o { :public object method foo {-np1 -np2 p1} { return $p1 } } ? {o foo -np1 1 -np2 2 -- -X} "-X" nsf.c: - when creation with an required configure parameter failed, delete the half-baked object to avoid confusing states. - improved handling of required configure parameters when classes are changed dynamically. When configure parameter are defined required, checking for the absence of required parameter was only performed at creation time. When objects were re-classed or their classes extended with required parameters, later calls to configure did not trigger exceptions. Now we check for the existence of the instance variable which addresses most of these points, but in future we might wish a more general solution (see comment for futures releases) nx::test: - deactivate calling overhead calculation, since this is not reliable (sometimes larger than the call). - Old TODO maybe obsolete: handling of recreate (see regression test for class-level properties) Could not find refernces about this in the parameters or properties tests. nsf.m4: - nsf.m4 currently unused (SC_PATH_NSFCONFIG and SC_LOAD_NSFCONFIG) We can delete it from the current version. nsf.c - fixed a bug in "info methods returns" in cases, where no returns info was available. - we can "/obj/ copy" now objects/classes containing * aliases * setter * ensemble methods * method protections Instead of handling cmd copying in NsfNSCopyCmdsCmd, it is replaced now by introspection. - extended regression test nsf.c - fixed a potental crash on destroy for objects having a wrapperless alias defined - removed obsolete function AssertionAppendPrePost() - removed obsolete function NsfNSCopyCmdsCmd() and ::nsf::nscopycmd (handled now more general on scripting level in the "copy" method) nx.tcl: - "copy" method: fixed copying of class-level per-object methods - extended regression tests serializer.tcl - added flag -objmap to Serialzer.deepSerialize to make serialzer usable for copying (-map is to coarse) - extended regression test nsf.c: - Eliminate all use of Tcl_GetStringFromObj() function. nx::test: - use the standard configure interface for configuring instead of own version - changed from nx::Test to nx::test (user never has to know that nx::Test is a class). - change test cases to newer interface - don't use "namespace import nx::*" in test cases when not required nsf.c: - reduce variable scopes - fix a bug in SlotContainerCmdResolver() when NSF_MEM_COUNT is activated - fix a small memory leak for PER_OBJECT_PARAMETER_CACHING - all cases detectable with --enable-memcount=yes are fixed - recheck Announce - concatenate Changelog - update next-scriping doc + examples, pdf-files? - build tar etc. as in README.release nsf.c: - dont't use the default of a invocation parameter in "configure" when the object is already initialized. The default is in general only used when the parameter is not specified. We do not want e.g. superclass to be reset to ::nx::Object, when configure is called on a class without arguments. - extended regression test - prepare for providing nx as a tcl module (.tm file). this is just a preparation, since for testing, one cannot set up a path that prefers a local copy over a global installed one (the global tcl-site is preferred over the one specified in e.g. TCL8_5_TM_PATH) Moving to tcl modules works in essence via git mv library/nx/nx.tcl tcl8/site-tcl/nx-2.0b5.tm This is really usable, when http://core.tcl.tk/tcl/tktview?name=86ceb4e2b6 is through monogodb: - updated to most recent version of c-driver (0.7.1) - adapted to nx 2.0b5 (use everywhere cget interface) - tested with mongodb 2.4.5 - added example scripts rosetta-sudoku.{tcl,html} and tk-ludo.{tcl,html} - added sample script doc/example-scripts/tk-geo.tcl mongodb: - integrated configuration of mongodb into toplevel configfile option: --with-mongodb=MONGO_INCLUDE_DIR,MONGO_LIB_DIR - added regression test files for mongodb support (lowlevel (tcl-only) and highlevel (nx based oo support)) - integrated mongodb-testfiles with "make test" - reduced verbosity of nx-mongo.tcl (added verbosty variable) nsf.c - don't call postcondition, when the command/invariant have returned already an error - fixed a bug where turning on assertions could swallow result-codes - fix potential crash when preconditions are empty - extended regression test serializer - fix object mehtod serializeExportedMethod: targetName might have been uninitialized nsf.c - reduce variable scope - remove uncalled static function nsf.c - fixed a bug where turning on assertions could swallow result-codes - extended regression test nsf.c: - added flag -checkalways to nsf::proc and nsf::asm::proc (for the latter just a placeholder for now). If the flag is used, it will cause argument testing independently from the "configure checkarguments" setting. To force argument checking always is useful e.g. for checking external values (e.g. in a web server) - nsf: added switch "-checkalways" to nsf::method::create - nx: added switch "checkalways" to "method" and "object method" - extended regression test xotcl2: - fixed "... info defaults ..." and "... info instdefaults ..." emulation in XOTcl 2 - fixed error message - extended regression test - bumped revision of nsf/xotcl/nx to 2.0b6 gentclAPI.tcl, generic/nsf.decls - make converter usable from c-based packages compiled with subs activated - add parameter parser and converter to stub tables generic/nsfStubLib.c: - change base stub table from XOTcl to NSF. - improve wording of error messages. generic/nsfPointer.c: - add reference counter to avoid double-inits and double-frees in case the table of converters is used from multiple interpreters generic/nsf.c: - made linearization monotonic (for multiple inheritance) via single-inheritance linearization merging while preserving overall linearization rules - added flag NSF_LINEARIZER_TRACE - extended regression test library/lib/make.tcl: - don't try to load nx when building pkgindex for a binary package (.so or dylib) mongodb - upgrade to mongo-c-driver to 0.8.1 - added new flag "-ttl" to mongo::index - there seems to be now a differen mongo-c-driver to be the preferred one, the old one is renamed to mongo-c-driver-legacy - link against nsf-stublib - bump version number to 0.2 generic/nsf.c: - add more assertions - ensure computation of requires orders for recursive merges mongodb: - add flag "-puts" to method "show" of nx::mongo::Class to turnoff output to stdout - handle empty find operations for "find first" - added method pretty_variables to output available variables of a class in a similar style as in the definition - added low-level method "close" to nx::mongo nsf.c: - new command ::nsf::object::alloc /class/ /obj/ ?/script/? alloc an object and execute script in the context. Can be used to regenerate an object in a old state. serializer: - fixed loading of objects with required data in the blueprint (many thanks for david hopfmueller for reporting this) - make use of nsf::object::alloc (1 command instead of 1 create + 2 evals) - these changes imprived laading time of blueprint by about 25% for OpenACS+xowiki - don't rely on the existence of a "trace" method nsf.c: - when ::nsf::object::alloc is passed an empty name (2nd argument), behave like "new" method nx: - allow copy of objects with required arguments - use ::nsf::object::alloc in "copy" method - don't depend on method "trace", use directdispatch instead - remove method "-noinit" (nsf::object::alloc makes it obsolete) - extend regression test serializer: - restore traces after object-serialize nsf.c: - fix stub provisioning for Tcl 8.6 - reduce verbosity for FreeUnsetTraceVariable - return TCL_OK, even when FreeUnsetTraceVariable() fails (warning stays) nx-mongo: - implement simple persistent handle management based on per-thread objects -nsf.c: - fix bug in interaction between uplevel method and interceptor transparency - fix bug in interaction between uplevel method from tcl procs - extend regression test build-system: - provide datarootdir to get rid of warning during configure nx-mongo: - updated documentation (switch back to mongo-c-driver, but comment usage of tagged version v0.8.1) - added support for rep types (allow for mappings between certain instance variables such as arrays or dicts to customizable representations in MongoDB) - added nx-serialize to test cases (simple state persistance for nx objects) - added nx-rep to test cases (rep types for "array" and "dict") - improve performance of mongo->tcl conversion by using predefined global strings nx-monogo: - Updated the mongo-c-driver and libbson to the actual tip version from github (this is a significant change, since 10gen essentially changed the officially supported c-driver of MongoDB) - mongo-c-driver was more or less new-implementation, since strucure and names changed in the mongo-c-driver substantially, serveral functions were added, several were dropped. The new interface supports now e.g. mongo URIs, and should be faster (by using collection objects instead of connection handles) - Although the low-level nsf interface changed significantly, the high level (nx level) interface remained unaffected. - Configure has now --with-mongoc=... and --with-bson instead of --with-mongodb - New commands: mongo::collection::open /mongoConn/ /dbName/ /collectionName/ mongo::collection::close /collection/ mongo::gridfs::store_string /content/ /name/ /contentType/ - Make use of the new collection handle mongo::count /mongoConn/ /ns/ ... -> mongo::collection::count /collection/ ... mongo::index /mongoConn/ /ns/ ... -> mongo::collection::index /collection/ ... mongo::insert /mongoConn/ /ns/ ... -> mongo::collection::insert /collection/ ... mongo::query /mongoConn/ /ns/ ... -> mongo::collection::query /collection/ ... mongo::remove /mongoConn/ /ns/ ... -> mongo::collection::delete /collection/ ... mongo::update /mongoConn/ /ns/ ... -> mongo::collection::update /collection/ ... mongo::cursor::find /mongoConn/ /ns/ ... -> mongo::cursor::find /collection/ ... - nsf::mongo::connect receives now a mongoc_uri https://github.com/mongodb/mongo-c-driver/blob/master/doc/mongoc_uri.txt - The gridfs interface allows now to store multiple revisions of a file - The gridfs interface allows now upload files from a string - The gridfs interface allows to refer to files by other attributes than just the filename (e.g. the mongo id). - Modified/new gridfile functions mongo::gridfile::create ?-source file|string? /gridfs/ /value/ /name/ /contentType/ mongo::gridfile::delete /gridfs/ /query/ mongo::gridfile::open /gridfs/ /query/ - Updated README - Updated regression test - Added editor hints for a more uniform appearance nsf.c: - change name of enumeratorConverterEntry to Nsf_EnumeratorConverterEntry, move it with NSF_ARG_* flags to tcl.h to make it available in derived modules using the converter - Added editor hints for a more uniform appearance nx.tcl: - raise an error, when an ensemble methods redefined a plain method nsf.c: - fix small memory leak in multiple inheritance code. - all regression tests reun cleanly with --enable-memcount=yes - let [current methodpath] return full path (similar to -path option in "info methods" - handle collateral damage in regression test due to changed result of "current methodpath" nx::traits: - handle ensemble methods correctly (use full method path for resolution) - add new regression tests for traits nx-mongo: - optional support for mongodb connection pools (compile time macro USE_CLIENT_POOL controls this, per default, this is on) - allow to pass "-metadata" to gridfile::create to ease metadata attachment to gridfiles - some conveniance improvements in nx-mongo.tcl (ability to ignore attributes in "bson encode", ability to unset attributes in gridfs, ...) - bump version numbers of nsfmongo to 0.3 and nx-monogo to 0.5 - represent BSON_TYPE_REGEX as pairs (regex + options) in the Tcl representation to preserve regular expression options - update to newest version of mongo-c-driver and libbson from github - tested with mongodb-c-driver 0.93.0 ======================================================================== TODO: - Why do we still have a method volatile in nx? Why not leave it as configure/cget configuration option only?! At least, I cannot recall the rationale behind keeping the method anymore :/ - remove / rephrase "//"-comments - ParamGetDomain(Nsf_Param CONST *paramPtr) does not work for enumeration types defined in derived packages, having their own constants - check deactivated tests in tests/serialize.test C(One), C(IgnoreAll), C(None2) and xlloc fix Stefan: doc items - make rough comparison table with NX, XOTcl, tclOO, itcl, Ruby, Python comparison NX vs. TclOO is most probably the most important Most general superclass Metaclass Per-object methods Per-Object mixins -- none, class, or class hierarchy Per-Class mixins -- none, class, or class hierarchy transitive mixins classes Per-object filters Per-class filters aliases Traits Composite Traits Method protection public/protected/private positional arguments none, leading args, arbitrary argument value checkers Create objects classes with no callable methods - doc/tutorial2.html - warnings for "numeric" names for args and nonpos-args? - special handling of values looking like nonpos-flags, but wich are not ones (-1, "- a b c", ....) in detection when to throw unknown. - interface of "variable" and "attribute": * add switch -array for "variable"? (Just setting is trivial, handling setters and incremental setter is more work) - extend mongo::gridfs::store_file with a switch -metadata to pass metadata together at gridfs file creation time - do we have to adjust the documentation in xotcl2 for object initialization? - maybe optional arg (true) to ::nsf::object::initialized to generalize -noinit - maybe: add a disposition=pipe - maybe: add "-asHTML" as style option to parametersyntax - MixinComputeOrderFullList() could receive a flag to store source classes in checkList - if the check on eg. info-heritage-circular in test/info.method.tcl reports a warning on exit, if we get an exception. - what to do with metadata analyzer? Still needed? Already replaced by new doctool? Does it have to run on make? Can doctool run on Make? - Higher binary compatibility for future versions: * It is not nice to have the full Nsf_Param structure in nsf.h (required for Nsf_methodDefinition in the c code generator) * It is not nice to have the full ParseContext structure in nsfmongo (required for the allocation of the parse context in the stubs) Adding fields to these structures would kill alder binaries - when alloc|dealloc are loaded via require, we have no redefined-protection on those. Since the script does not know, on which class|object these are defined one cannot make assumption on these. Problem? - The structure of the script body requires currently that "class|object ?-per-object?" is inserted at the 1nd pos. This is not sufficient, if we would like to test in this script, whether the first arg is e.g. a class. - document value added replacements of Tcl functions - configure parameter type forward: - regression test - get rid of eager tcd creation (optimization, can go to future releases) - slotmachinerie 2 - should we deactivate add/delete for non-multivalued cases? - allow noarg+default/initcmd ? - default/initcmd/subsdefault: can we simplify these? or add messages for conflicting usages. - Makefile/::nsf::config: Integrate git meta-data (commit hash, branch/tag labels) - doc: * no-accessor properties/slots are still reported as methods: class * method parameters need indentation ... * method ensembles are reported as "Implementation details: alias", is this ok? * doc validator reports wierd info submethods: info definition, info names, info objects -> mean "info slot *" ... smells like generator garbage ... * inconsistency: "info slot *" are built on "slotsobjects" which does not take -source and -closure parameters ... still, they are in the NX method interfaces ... review and document accordingly. * sub-method cross-references per @use does not work (parameters are not reproduced, probably no [:origin] resolution is performed: See the case for "info properties" -> "info slot definition" * "info method": elaborate on the options, right now the doc is minimal ... * "info method" -> why does the parametersytnax does not report all enumeration literals, rather than ?infomethodsubcmd? ??? * fix sub methods validation reporting -> mismatch? * Ensemble methods: obj info & friends ... there is no parametersyntax reported; add something literal in the template: ? * Object|Class mixin|filter guard -> how to document (and not reported by nxdoc as missing either, as their as slot-specific)? And link to Class class filterguard|mixinguard ... Why not defining the latter as ensembles "Class class filter|mixin guard"? * Ensemble methods, i.e. intermediate ones, should not be filter by inheritance in the nxdoc output. For example, info() in Class shares many details of info in Object, but it does not visualize this quasi-inheritance * @package.@require(): really needed? * @package.@version: fix validation mode ... expected/actual version numbers are not compared ... * NextScriptingLanguage/index.html: glossary entries in nsf.nxd should be sorted (in the source) ...... Maybe, a single glossary.nxd file? SS: Right now, the name of the nxd file derives from the the script name. I mark this as TODO for the future. * doc/langRef2.xotcl vs library/xotcl/doc/langRef.xotcl * @author: how to visualise the authorship in the generated markup (yuidoc)? - do we need contains in nx? - nsf::proc * check, if there are parameter types that should not be applicable for nsf::proc * toplevel (object less) introspection - documentation * migration guide 3.8. Dispatch, Aliases, etc.: to be done or omitted - check performance implications of value checker - library + XOTcl apps - work on binary packages of xotcl (store + xml) - nicht gewartete/nicht getestete library aus distro entfernen? - migration von einzelnen paketen nach next? von welchen? Ein paar Punkte im folgenden könnten obsolet sein: TODO "Kleinigkeiten" - should we continue to work on the problem of the interp-aliased class, exported from one ns, imported into another one? - constants in type converter (in and out) #if 1 /* TODO: the following check operations is xotcl1 legacy and is not generic. it should be replaced by another methodproperty. Most of the is*String() definition are then obsolete and should be deleted from xotclInt.h as well. */ if (isCheckString(methodName)) { return TCL_OK; } #endif For future releases (after first alpha/beta release) - cmd introspection: nsf defines a commands (e.g. nsf::proc) and unregistered methods. The interfaces of these commands can be queried via methods % nx::Object info method parameters ::nsf::proc -ad:switch procName arguments body % nx::Object info method syntax ::nsf::proc /cls/ proc ?-ad? /procName/ /arguments/ /body/ % nx::Object info method definition ::nsf::proc Warning: Could not obtain alias definition for proc... which return only patially correct results (the first is correct, the second one is misleading, the error message can be improved for the third case. maybe ::nsf::info command parameters|syntax /cmd/ might make sense, but there might be more candidates for nsf::info around. OTOH, we have already nsf::object::exists, nsf::is, etc. * generalizing parameter-specific per-object info Now we have __initcmd(varname) for init-cmds of varitable traces __cmd(varname) for the eval-ed cmds (mostly for documentation purposes to postprocess the init block We could need __required_satistfied(varname) to handle required parameter aliases As generalization, we could use a dict __parameterstate(varname) or even __parameterstate with a dict to collect the various aspects. for performance reasons, we do not want to set this variable too frequent, serialization and blueprint aspects have to be considered. This would as well address cases, where the parameter has a different name than the associated varianle (e.g. private properties) * Currently, in NX, specifying mandatory parameters may break object construction as init won't receive any arguments (no residual args). We should provide a warning when a user defines arguments for init (or provide some other syntactic sugar) * extend traits (object-specific traits, test cases, etc.) * add maybe "::nsf::object::property /obj/ volatile 0|1" to alter volatile state. * Reduce / remove hard-code names. Right now, "method"/"alias"/ "forward" is returend by "info definition" introspection. This is not serious, since e.g. XOTcl handles this on the script level by mapping these names to the XOTcl counterparts. We could as well make this configurable via the object-system parameters. * Consider alternate method name/place for subcmds (and/or slots) on classes - currently, there are potential conflicts between slots and ensemble objects - provide a different place in the namesspaces could simplify this * Cleanup the set of active filters when filters are removed (only relevant for the speed of scripts with filters and a high number of instances) * Ensembles - 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. * Serializer: handing of xo::at_cleanup in serializer (either generalization or move to OpenACS/aolserver init/naviserver init) * Parameter/argument handling - Add an unknown handler for unknown non-pos args to Argument parser. The problem is to find a way to aviod method deletions or redefinitions or to recover from these gracefully (when e.g. the unknown handler deletes the parameters currenlty being worked on). - Canonical parameter representations: "p:integer,multivalued" => "-name p -type integer -multivalued" "x:type,arg=::D d1" => "-name x -type type -arg ::D -default d1" - Argument passing of C functions is currently based on an interpreter of the argument lists. It should be possible to turn the interpreter into a compiler to speed up argument passing. But maybe, this would bloat the code-size. - Use parameter syntax in genTclAPI - better handling of "c1 cget -noinit" ? * experimental features: - document/extend/generalize/remove the experimental object properties perobjectdispatch and keepcallerself - behavior on keepcallerself on ordinary dispatches with implicit/explicit receiver (currently the flag is ignored, the code just commented out) * C-Code * Several of the tracing options in nsf.h could be replaced by DTrace * Rework implict namespace completion (NameInNamespaceObj(), maybe based on BeginOfCallChain()). * Rework C-interface (maybe for post-alpha, but we have be first clear on scope and intention. A possibility would be to provide all entries from gentclAPI, but we would loose most likely static property and the newly achieved ease of changing is effectively frozen by the stubs interface, which has to be stable. * NsfClassListAdd() and friends could be made generic * Coroutines - extend coro regression test - coro-enable nsf::proc * renable/translate deletex XOTcl demo scripts, such as e.g. those from library/xotcl/apps/scripts
