* added methods ::nsf::methods::object::class and ::nsf::methods::class::superclass in order to make faster and nicer looking objectparameters (compared with forwarders) * nx: changed parameter -class to use ::nsf::methods::object::class * ns: fixed chicken egg problem of method objectparameter needing objectparameter by creating/destroying slot Class::slot::dummy; otherwise default values for slots would not be available * reduced verbosity of parameter forwarder

* provided a fast path implementation for "defaultmethod" * provided default system methods for "init", "defaultmethod" and "unknown" * provided handles for system methods "alloc", "dealloc", "recreate", and "defaultmethod" * strip in dispatch invocations of "unknown" potental leading colons * removed c-level implementation of init again, since scripted one can be used now as well in registration of createobjectsystem * reduced verbosity * added defintions such that these methods can be loaded via ::nsf::method::require ::nx::Object unknown

  1. … 4 more files in changeset.
* added C-implemented method "init" for orthogonality * allow specification of system method handles in nsf::createobjectsystem * automatically register alias, when system-method handle was provided and a same-named method is defined

- reduce verbosity

nx: * removed methods ::nx::Class.recreate and ::nx::Class.recreate from predefined method-set ::nx::Object.configure from predefined method-set

* added defintions such that these methods can be loaded via

::nsf::method::require ::nx::Class recreate

::nsf::method::require ::nx::Object configure

nsf:

* added CallDirectly() wrapper for calls to "init"

- nx: * removed methods ::nx::Class.alloc and ::nx::Class.dealloc from predefined method-set

* added defintions such that these methods can be loaded via

::nsf::method::require ::nx::Class alloc

::nsf::method::require ::nx::Class dealloc

* make explicit that "method ... require" returns a method-handle

* removed misleading reference in error message, when a class-spefic

method was called on an object; solution is somewhat dangerous for

potentially unknwon client data

* added regression tests

- serializer: catch for object-level alias apparently not needed anymore (search for ns_cache_flush) - silence compilation when compiled without dtrace

- changed names of var handling commands in nsf: ::nsf::existsvar => ::nsf::var::exists ::nsf::importvar => ::nsf::var::import ::nsf::setvar => ::nsf::var::set

  1. … 10 more files in changeset.
- removed hardcoded name "init" from CallConfigureMethod() - improved documentation - removed isInitString()

- Fixed cases of -flag=$value for type switch outside the context of "nsf::procs -ad" - extended regression test

- changed named of method handling commands in nsf: ::nsf::provide_method => ::nsf::method::provide ::nsf::require_method => ::nsf::method::require

- fix typo

- changed named of method handling commands in nsf: ::nsf::methodproperty => ::nsf::method::property ::nsf::method => ::nsf::method::create ::nsf::methoddelete => ::nsf::method::delete ::nsf::alias => ::nsf::method::alias ::nsf::forward => ::nsf::method::forward ::nsf::setter => ::nsf::method::setter (updated regression test, docs, ...)

- fixed potential crash with -param:switch - added "... info method exists ...."

DTrace * renamed object-create into object-alloc (counterpart of object-free, no confusion with create) * fire probes as well for classes created by the object system

- added first version of "nsf::methoddelete" - extended regression test - updated TODO

DTrace: * add probes for object creation and freeing * add sample d-script for object bookkeeping

DTrace: * added "nsf::configure dtrace on|off" for skipping package initialization (to be handled in D script) * make compliation clean

- dtrace improvements: * track objects in method invocations * trace result codes in method-return * add some dtrace sample scripts

- first steps towards DTRACE support

- profiling: return object data with method information

- cleanup and documentation of nsf-specific interp state - nsf::configure: added an option "profile on|off" (per default off)

- configure: added flag --with-profile to enable profiling support

  1. … 3 more files in changeset.
- made default setting more compatible with XOTcl 1 * set variables to defaults only when not set already * flag init_called already before init is called, not afterwards (a call to "configure" within init does not clear the already set instance variables)

* Backport of nsf to handle partial implicit deletes

- Altered Nsf_NextHashEntry() to re-init hSrchPtr when the number of expected entries differs from the number of real entries. This fixes a bug that Michael Aram detected, that happens when multiple hash buckets exist, but on deletion of an hash entries triggers some other deleted from the same hash table. - extended regression test.

- added profile support for nsf::proc

- The fix of yesterdays subst reference counting bug triggered an other problem: If the last arg was "args", the flags array for checking the need for decr of refcounts was not extended. There are multiple possible fixes, i have just extended the flags array for now as well. - When profiling is activated, perform now a more sane shutdown order, all hash tables are now correctly freed. - Improve behavior, when object system creation fails - Drop function NsfProfilePrint()

- nx.tcl: provide caching for computed values of object slots to make method objectparameter nearly twice as fast; direct changes on slots require a reconfigure call. - nsf.c: removed SUBST from shadow commands (does not appear to be necessary any more) - nsf.c: fixing a memory leak (some substituted values were not freed correctly) - nsf.c: fix potential crash for epoched cmds - some minor updates for profiling support
