- use functions IsRootClass(), IsRootMetaClass() and IsBaseClass() to access object/class properties - add gcc attribute "pure"

  1. … 2 more files in changeset.
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"

- harden code

- provide contextObj when required argument is missing

nsf.c: - added options to filter output from ::nsf::cmd::info parameter options (args, syntax, parameter) - deleted: - "/obj/ info lookup configure parameters ?pattern?" - "/obj/ info lookup configure syntax" - added: - "/obj/ info lookup parameters /methodName/ ?pattern?" - "/obj/ info lookup syntax /methodName/ ?pattern?" This covers as well - "/obj/ info lookup parameters configure|create|new|... ?pattern?" - extend regression test

- remove dead code

- white-space change

- improve error message

nsf.c, gentclAPI.tcl: - new argument types "virtualobjectargs" and "virtualclassargs" for context-specific argument resolutions: when a context object is provided, arguments of type "virtualobjectargs" are determined based on the slots applicable for the object (like "... lookup ..."), arguments of type "virtualclassargs" are resolved against a class. These types are used as follows: /obj/ configure /virtualobjectargs/ /cls/ create /name/ /virtualclassargs/ /cls/ recreate /name/ /virtualclassargs/ /cls/ new ?-childof /obj/? /virtualclassargs/ This new feature allows us to provide better error messages and to make much of the "... info ... configure parameter ..." infrastructure much less important. - For "virtualclassargs" we need the functionality to obtain from the C-Code based on a class the configure parameters applicable to objects of this class. - add argument "-context ..." to "cmd::info" to pass the context object (so far the only place where the context-object is used) - object system configuration parameters changes: new: -class.configureparameter new: -object.configureparameter removed: -class.objectparameter

  1. … 16 more files in changeset.
nsf.c - renamed parameter::get -> parameter::info - renamed method::get -> cmd::info

  1. … 10 more files in changeset.
gentclAPI.tcl: - handle duplicated domains by folding these to a single definition

nsf.c:

- added command nsf::method::get.

Rationale: provide a central place to obtain information

about all kind of method handles, which might be

- scripted and c-based methods

- nsf::procs

- plain tcl procs

- cmds (with and without paramter definitions)

- make results of ListMethod() robust against missing

information (e.g. plain tcl cmds, missing object registrations,

etc.)

- factor out common code for ListMethod call sites

for per-object methods, instance methods and procs/cmds

to ListMethodResolve()

- return errors from failing converter registrations

- extend regression test (new test set nsf-method.test)

- make error-checks as unlikely to succeed

- return class of desired object in nsf::parameter::get when provided

  1. … 1 more file in changeset.
nsf.c: - extend nsf::parameter::get to obtained more detailed information for obejcts/classes/metaclasses/baseclasses and specified types - extend regression test

  1. … 2 more files in changeset.
nsf.c - force again literal "-guard" in a "mixinreg" type to avoid potential confusions - Base nsfRelationSet for mixins on cmds rather than TclObjs to avoid confusions and duplication of guard detection logic - Add interp to NsfMixinregGet() and NsfFilterregGet() to be able to return error messages - return more error message from mixinreg converter - provide at least minimal support for "funny class names" (i.e. containing spaces) - FinalObjectDeletion: don't enforce namespace = 1 for cases with wierd namespace deletion order - extended regression test

  1. … 5 more files in changeset.
- added methods "info lookup filters ?-guards? ?/pattern/?" and "info lookup methods *-guards? ?/pattern/?" - extended regression test

- improve handling of space in object names

- name parameter option "slotset" instead of "slotassign"

  1. … 10 more files in changeset.
- renamed nsf::relation to nsf::relation::set and added nsf::relation::get in accordance with nsf::var::get

  1. … 17 more files in changeset.
nsf.c: - added nsf::var::get and "::nx::var get" to provide selector based interface for variable reading (used in slotmethod get of nx::VariableSlot)

- cleanup of nx.tcl and TODO

  1. … 8 more files in changeset.
nsf.c: - finish implementation of NsfForwardPrintError() - use NsfForwardPrintError() in ForwardArg() for all error messages

  1. … 1 more file in changeset.
- added likely/unlikely to result == TCL_OK etc.

nsf.c: - fix one more subtle case of an error being swallowed: for xotcl, the constructor returns the list of residual arguments. In case there was an error, it was possible that the returned residual arguments overwrote the error message in the interp result

nsf.c: - rename default slot methods add/get to value=add/value=get - provide an error message, when refering to a non-existing slot object

  1. … 1 more file in changeset.
- allow configuration of internally called "slot.get" and "slot.assign" methods via objectsystem::create

  1. … 1 more file in changeset.
nsf.c: - allow parameter option "method=" for slotassign as well. rationale: this allows to use the parameter "forwardername" to specify a different forwarder target method (e.g. in case of object-mixins). The method is used both in "configure" and "cget". - allow methodname to consist of max tow words in relation slots (e.g. "-methodname {mixin set}"}
