- moved mixin reg type converter to a new file (nsfObj.c)

  1. … 8 more files in changeset.
- 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 NsfCallUnkownHandler()

- 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

  1. … 12 more files in changeset.
- nsf.c: changes to use trunk-branches with and without TclStackAlloc() and TclStackFree()

  1. … 1 more file in changeset.
- nsf.c: * handling of same named per-object and provided slots for Class objects * per-object slots are saved now under <obj>::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

  1. … 6 more files in changeset.
- 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()

  1. … 3 more files in changeset.
- 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

  1. … 8 more files in changeset.
- 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).

  1. … 7 more files in changeset.
- gentclAPI.tcl: * renamed "nsfCmd" to simply "cmd", since the code can generate arbitrary tcl commands * allow type "int" in the .decls files - nsf.c * move several functions from "static" to "external" to make the code generator usable for submodules as well

  1. … 7 more files in changeset.
* 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 interals around.

  1. … 4 more files in changeset.
* 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)

  1. … 3 more files in changeset.
* added C-implemented method "init" for orthogonality * allow specification of system method handles in nsf::createobjectsystem * automatically register alias, when system-method handle was provided and a same-named method is defined

  1. … 5 more files in changeset.
- removed hardcoded name "init" from CallConfigureMethod() - improved documentation - removed isInitString()

  1. … 1 more file in changeset.
- Fixed cases of -flag=$value for type switch outside the context of "nsf::procs -ad" - extended regression test

  1. … 3 more files in changeset.
- fix typo

DTrace * renamed object-create into object-alloc (counterpart of object-free, no confusion with create) * fire probes as well for classes created by the object system

  1. … 5 more files in changeset.
DTrace: * add probes for object creation and freeing * add sample d-script for object bookkeeping

  1. … 5 more files in changeset.
DTrace: * added "nsf::configure dtrace on|off" for skipping package initialization (to be handled in D script) * make compliation clean

  1. … 7 more files in changeset.
- dtrace improvements: * track objects in method invocations * trace result codes in method-return * add some dtrace sample scripts

  1. … 10 more files in changeset.
- first steps towards DTRACE support

  1. … 5 more files in changeset.
- cleanup and documentation of nsf-specific interp state - nsf::configure: added an option "profile on|off" (per default off)

  1. … 5 more files in changeset.
- added profile support for nsf::proc

  1. … 3 more files in changeset.
- 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()

  1. … 5 more files in changeset.
- 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

  1. … 8 more files in changeset.
- reanimated NSF_PROFILE

  1. … 5 more files in changeset.
- update slot uml diagram - fixed incorrect (unwanted) call to unknown that caused creation of objects names __unknown when classes could not be resolved

  1. … 4 more files in changeset.
- 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.
