- generic/nsf.c, ObjectDispatch(): Re-arranged the handling of fully-qualified method dispatches with the selectors resolving to existing objects and, in particular, nested (namespace-qualified) objects. Prior to that, dispatches such as "::C ::parent::child" were not covered appropriately: ::parent was reported as valid regObj and so the dispatcher continued to dispatch to the cmd "::parent::child" in the self-context ::parent::child ... with unwanted side-effects (e.g., XOTcl's unknown handling was bypassed). - tests/methods.test: Added basic tests on the (current) handling for such ::* dispatches and a specific test set on the intended XOTcl behaviour.

- start error messages with a lower case word for consistency and to follow closer to Tcl's conventions

  1. … 2 more files in changeset.
- implement escaping for comma in value of parameter options: escaping in values can be achived via duplicating the comma. - extend regression test

  1. … 2 more files in changeset.
- explorative implementation of object method dispatches with KEEP_CALLER_SELF and no NSF_PER_OBJECT_DISPATCH - extend regression test

- remove debug line

- add regression test for keepcallerself with and without perobjectdispatch

- serializer: * pertain perobjectdispatch and keepcallerself in serializer * extend regression test

- 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

- extended regression test

- tcl86.test: better implementation of method "each", cleanup and extension of enumerator tests

  1. … 1 more file in changeset.
- extended regression tests for yield - implemented "next" for ruby-like enumerators (each needs still more work)

  1. … 1 more file in changeset.
- 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")

  1. … 2 more files in changeset.
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

  1. … 4 more files in changeset.
- 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

- improve error message to indicate, that nsf refuses to overwrite (redefine) some cmds

  1. … 1 more file in changeset.
- don't allow method to overwrite child object - extended regression test - documented new feature as incompatibility with XOTcl 1

  1. … 4 more files in changeset.
- don't allow object creation to overwrite non-object cmds (e.g. procs)

  1. … 3 more files in changeset.
- tests/serialize.test: Added some basic regression tests, in particular to challenge the filter options provided by Serializer->deepSerialize() and Serializer->all(). - Included a test for commit 595e6a2. - Along the line, two minor issues where fixed: 1) Set Serializer->ignore() to public, otherwise the various external message sends to this method would fail; 2) Object-serialize() did not distinguish between serialising a per-object or per-class container properly; as a consequence, per-object containers were not restored at all. Add a test covering this.

- treating incompatible forwarding to slot vs. slot option noaccessor - extended regression test

- Forward setting of object parameters to the slot object, when assign method is user-defined on the slot object - Cleanup and extend regression test

  1. … 3 more files in changeset.
- remove debug output

- changed object->flags from "unsigend short" to "unsigned int" - reintroduced NSF_TCL_DELETE to address bug flagged from memdebug - extended regression test

  1. … 3 more files in changeset.
- extend regression test for interactions between "keepcallerself" and "perobjectdispatch" - some minor cleanup

  1. … 2 more files in changeset.
- fixed potential crash from method caching, when permissions on cmds are changed and become e.g. unresolvable - removed flag allowmethoddispatch, since behavior can be achived via private flag. - extended regression test

  1. … 7 more files in changeset.
- deacitivate for the time being allowmethoddispatch (make it behave always like true) - added instead new flag "perobjectdispatch" to make behavior of ensembleobjects 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

- use alias-stubs for aliases pointing to objects. This allows us to distinguish between cases, where an object is dispatchable 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 dispatchable, no matter, how allowmethoddispatch is set. - direct subobjects of objects are currently on dispatchable when allowmethoddispatch is set.

- 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 sitations, 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

Extend backport of handling of dashses in XOTcl's configure method to perform a more eager search for command begins. Extended regression test.

  1. … 2 more files in changeset.
- Added exerpimental 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 visablilty of objects with "allowmethoddispatch" false in "info methods" and "info search methods" - extended regression test
