- generic/nsf.c: Fixed [current callingmethod] for submethods (i.e., reporting submethods as calling methods, including their methodpath). Added tests covering the fix (see tests/submethods.test). - generic/nsfStack.c (CallStackMethodPath): Re-arranged the traversal slightly, to escape non-ensemble frames (eval CFRAMEs) as parts of the method path. Added test (see tests/submethods.test). - library/nx/nx.tcl: Corrected the impl of Ensemble->defaultmethod() (e.g., used self instead of current) - tests/disposition.test: Fixed test cases turned out to be false positives. Before the fixes, [current methodpath] gave non-empty results for simple object aliases.

- generic/nsf.c / NsfOConfigureMethod(): Configure adds frames to its callstack context, however, so far the callstack modifications have not honoured the fact that configure() can be called from uplevel'ed call sites. The callstack context resulting from a prior uplevel was erased by the call frame introductions. As a consequence, parameter-dispatched methods found themselves in a wrong variable frame context. The suggested patch adds uplevel awareness in the most generic way I could think of. The entire test suite runs against the patched NsfOConfigureMethod(). However, I might be missing unwanted consequences for untested cases ... we need to think of further test scenarios ...

- generic/nsfStack.c: Revised my former patch for traversing callstacks under ensemle dispatches. We fixed the traversal-ending gateway expression; and added transparency for INACTIVE frames when assembling the method path. Added further tests, remain to be completed ...

- nsfStack.c / CallStackMethodPath(): Providing a fix for reporting method paths correctly when dispatching to ensembles from alias parameters. Prior to that fix, the intermediate (and inactive) CMETHOD frame wrapping configure() calls caused [current methodpath]s to report empty string elements. Added some test cases. - nsf.c / ObjectDispatch(), DispatchUnknownMethod(): When testing objects as alias parameter targets, I found cases when the default (C-level) unknown handler was invoked upon. The result was an unknown message which reported the delegator object as "unknown" method! This was due to injecting the delegator object into the argument vector at position 0, subsequently used by the C-level unknown handler. First, I tried to make the C-level unknown handler aware of the ensemble call context (by funneling through the CSC and frame flags) but this turned out to be complicated to achieve this simple task. As an alternative, I suggest the following patch: The first argument in unknown calls is treated as a list, and dependening on the call context (ensemble vs. non-ensemble) contains all the necessary call data. For ensemble methods, it is the delegator object, the entire method path (as returned by [current methodpath]), and the actual unknown selector. The default C-level handler, treating the call info as list, resorts to reporting the last element of the list which is always the unknown selector. Custom (ensemble-level, application-level) unknown handler can wrap and further process the information as necessary. To demonstrate the usefulness, I rewrote EnsembleObject->unknown() accordingly. I checked for Tcl_Obj leaks. - Added some tests on objects as targets of alias object parameter. To be continued.

* 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.

- 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.
