- 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. … 5 more files in changeset.
- use Tcl's EXTERN macro instead of "extern"

  1. … 2 more files in changeset.
- reduce variable scope

- 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.

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

Merge branch 'master' of ssh://alice.wu-wien.ac.at/usr/local/src/git-repo/nsf - use fixed array size for method_definitions for MSC

Conflicts:

generic/nsf.c

- Cleanup for compilation under MSC (avoid unsupported forward declaration of array) - further documentation of functions, better grouping of functions

- C89/C99 do not allow forward declaration of arrays with "static" storage classifiers (a feature which is a gcc extension only). For MSVC compat, I fixed these occurrences and verified that nsf builds with "gcc -std=c89 -pedantic". - generic/gentclAPI.tcl: Modified the print statements for two array forward declarations (method_definitions, enumeratorConverterEntries)

Fixed memdebub build

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

  1. … 2 more files in changeset.
- fixed NRE memory management (for Tcl 8.6) by refactoring alias handling

  1. … 1 more file 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. … 6 more files in changeset.
Merge branch 'master' of ssh://alice.wu-wien.ac.at/usr/local/src/git-repo/nsf

- 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

  1. … 7 more files in changeset.
- Used "gcc -ansi" to test ANSI compatibility (with MSVC in mind) - generic/nsf.c, generic/nsfShadow.c: Fixed some non-ANSI comments - generic/nsfError.c: Relocated a declaration to the beginning of the scope block (MSVC shouted here) - generic/nsfInt.h: Made sure that NSF_INLINE is only set in non-ANSI gcc builds, added a tiny portability wrapper for va_copy (to support MSVC and the gcc/clang ANSI mode)

- nsf.c: start all error messages with a lower case word for consistency and to follow closer to Tcl's conventions

  1. … 13 more files in changeset.
- 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

- improve handling of multiple error messages in a single command

Extend handling of dashses in XOTcl's configure method to perform a more eager search for command begins (same change as in XOTcl 1)

  1. … 1 more file in changeset.
Fix typo in nsf::predefined

Fix typo in ::nsf::deprecated

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

Don't overwrite error messages from __unknown handler in several situations (superclass, parameter class, mixin class)

  1. … 1 more file in changeset.
- simplified usage of ObjectName() and ClassName() macros (no caller parenthesis needed) - added exerpimental object property keepcaller self (currently only evaluated by aliased objects)

Version generated for Tcl 8.5 - maybe we keep this out from the repo in the future

Allow to pass casts to macros ClassName and ObjectName
