genttclAPI.tcl: - added option "-flags", which can be used for every parameter. example: .... -flags NSF_ARG_NOLEADINGDASH .... - experimental: use NSF_ARG_NOLEADINGDASH for pattern "info subclass" to improve error messages.

nsf.c: - checked, that all CallDirectly() cases, where method is dispatched (no direct call) are covered by the regression tests - avoid double memcpy() in dispatch recreate by using ObjectDispatch() rather than CallMethod() - removed memcopy() in call-directy for "create" - some more cleanup

nsf.c: parameter passing reform - don't pass full argument list for filteing methods calle further methods from C (such as new/create/... ) to allow processing of e.g. "--" in "new" to separate arguments to "new" cleanly from arguments passed to "create". Now we can use e.g. "C new -- -childof 123" in case class C has a property "childof". - extend c-generator to accept option "-objv0" to pass the original "objv[0]" to the called command. Since we had previously "allargs", we have to pass the objv[0] now differently - more thorough checking ISOBJ(someObj) macro for asserts (use "assert(ISOBJ(someObj))" instead of just "assert(someObj)") - extend regression test

Adding to the state of the method-path introspection reform; introducing CallStackGetFrame() which can also be used to implement CallStackGetTopFrame

- move NsfMethodNamePath() out of NsfUnexpectedArgumentError() and NsfUnexpectedNonposArgumentError()

- no need to call NsfMethodNamePath in NsfArgumentError()

nsf.c: - added option "-dependent" to "info subclass" - extended regression test

nsf.c - base MixinInvalidateObjOrders() on DependentSubClasses() and avoid the need of using a separate hash table for class-mixin handling. The new implementation is several times faster and improves the speed of the functions CleanupDestroyClass(), SuperclassAdd() and NsfRelationClassMixinsSet(). Adding a class-mixin to ::xotcl::Object in OpenACS is more than 4x faster. - remove obsolete function MixinResetOrderForInstances() - rename ResetOrderOfClassesUsedAsMixins() to ResetOrderOfObjectsUsingThisClassAsObjectMixin() - used consistenlty DependentSubClasses() instead of TransitiveSubClasses() for invalidations. - extend regression test

nsf.c: - improve performance of MixinInvalidateObjOrders() by about 30% by recomping the list of the dependent classes over and over again, since MixinInvalidateObjOrders() iterates over the full list already. - Document NsfRelationClassMixinsSet() and add nonnull declarations and the usual assertions()

nsf.c: - new function DependentSubClasses() to determine all classes that inherit from a given class. The result extend TransitiveSubClasses() by including class mixin relationships. - simplify NsfParameterCacheClassInvalidateCmd() by using the new function DependentSubClasses(). With the new implementation, NsfParameterCacheClassInvalidateCmd() is as efficient as before without to MostGeneralSuperclass optimization (but being complete now) when working on the root classes (an more efficient on subclasses).

- fixed error message for forward ... onerror and method paths. The command "C object mixin" returns now "::C object mixin add|clear|delete|get|guard|set" and not "::C mixin add|clear|delete|get|guard|set" as before.

- rename nsf::parameter:invalidate::classcache -> nsf::parameter::cache::classinvalidate nsf::parameter:invalidate::objectcache -> nsf::parameter::cache::objectinvalidate reasons: (a) remove single colon inside the name, (b) put verb to the end

nsf.c: - cleanup of NsfParameterInvalidateClassCacheCmd(): performance improvements. After the fixing of indirect mixin validation, performance of invalidation went up by a factor of 5. At least, in some important cases (invalidation of rootclasses like nx::Object / xotcl::Object), we are again on the same level as before (actually slightly faster).

- nsf.c: - Let "/cls/ info mixinof -closure" return as well implicit mixin classes to make it easier to determine class dependencies.

Example:

nx::Class create M0

nx::Class create M1 -superclass M0

nx::Class create M2 -superclass M1

nx::Class create C

nx::Class create D -superclass C

C mixin add M2

# M2 is mixed into C, and implicitely into D

#

# Since M2 is a subclass of M1, classes C and D depend as well

# on M1 and M0, as seen in the heritage:

? {C info heritage} ":M2 ::M1 ::M0 ::nx::Object"

? {D info heritage} ":M2 ::M1 ::M0 ::C ::nx::Object"

# previously, only "M2 info mixinof -closure" showed the

# mixin relations, even with "-closure", while M1 and M0 did not.

? {M2 info mixinof -closure} "::C ::D"

# now these show the same relations (in this example).

? {M1 info mixinof -closure} "::C ::D"

? {M0 info mixinof -closure} "::C ::D"
