- 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 ...

- Reduced verbosity in nsf.c, reactivated a test case

- tests/forward.test, tests/methods.test: Remove some intermediary statements

- 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.

- 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()

- correct result type

- 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

- tests/parameters.test: Slight extension of test case on a re-assignment of per-ob defaults.

- library/nx/nx.tcl: Fixed Attribute->reconfigure() to cover the reconfiguration of a default value in the per-object case ... - tests/parameters.test: Added Victor Mayevski's example as a proper test case. Details need to be discussed ...

- 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

- 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

- generic/nsf.c: Shuffled around the word order and adding some quoting in the error message for enforcing multivalued, non-empty list multiplicities; to differentiate between parameter name and value literals etc.

- tests/disposition.test: Added tests covering "dispos vs. return checker" and "dispos vs. uplevel/upvar"

- library/nx/nx-zip.tcl: added a zip file generator as package

- add various "namespace eval {}" to make package indexer happy

- nsf.c: no good reason to disallow user defined types for for alias, forward or initcmd

- generic/nsf.c: Re-introduce trimming for "names" of unknown parameter options.

- generic/nsf.c: Aligned error messages for parameter options; Re-arranged control flow in ParamOptionParse() slightly, do allow for [string is] types being used as options of disposition types. Refactored code slightly (e.g., removed unneeded, intermediary Tcl_Objs). - tests/disposition.test: Extended test suite, in particular, for covering multiplicity types as parameter options of disposition types. - tests/parameters.test: Adjusting for rephrased error messages.

- genAPI.decls and nsf.c: bring cmds in same order - nsf.c: align naming conventions

- 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

-blank changes

- 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
