- 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

  1. … 2 more files in changeset.
- changed names of var handling commands in nsf: ::nsf::existsvar => ::nsf::var::exists ::nsf::importvar => ::nsf::var::import ::nsf::setvar => ::nsf::var::set

  1. … 12 more files in changeset.
- removed hardcoded name "init" from CallConfigureMethod() - improved documentation - removed isInitString()

  1. … 1 more file in changeset.
- Fixed cases of -flag=$value for type switch outside the context of "nsf::procs -ad" - extended regression test

  1. … 3 more files in changeset.
- 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, ...)

  1. … 24 more files in changeset.
- fixed potential crash with -param:switch - added "... info method exists ...."

  1. … 6 more files in changeset.
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

  1. … 5 more files in changeset.
DTrace: * add probes for object creation and freeing * add sample d-script for object bookkeeping

  1. … 5 more files in changeset.
DTrace: * added "nsf::configure dtrace on|off" for skipping package initialization (to be handled in D script) * make compliation clean

  1. … 7 more files in changeset.
- dtrace improvements: * track objects in method invocations * trace result codes in method-return * add some dtrace sample scripts

  1. … 10 more files in changeset.
- cleanup and documentation of nsf-specific interp state - nsf::configure: added an option "profile on|off" (per default off)

  1. … 5 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)

- 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

  1. … 3 more files in changeset.
- 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()

  1. … 5 more files in changeset.
- 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

Merge branch '2.0.0-develop' of ssh://alice.wu-wien.ac.at/usr/local/src/git-repo/xotcl into 2.0.0-develop

  1. … 2 more files in changeset.
- nsf.c: provide low-level commands for managing profile data

  1. … 1 more file in changeset.
Adding buffer-local emacs settings to the *.c files

  1. … 11 more files in changeset.
- reanimated NSF_PROFILE

  1. … 5 more files in changeset.
- nsf::relation: fixed error message when receiving and invalid class for relation type "class"

  1. … 2 more files in changeset.
- update slot uml diagram - fixed incorrect (unwanted) call to unknown that caused creation of objects names __unknown when classes could not be resolved

  1. … 4 more files in changeset.
- added experimental flag WITH_IMPORT_REFS to deactivate automated alias deletion (seems, that this solves all issues we had before) - added flushing of bytecode on alias registration - added regression test

  1. … 2 more files in changeset.
- added flag to AliasGet() to leave optional error message if alias data is removed - some cleanup in NsfProcAliasMethod(): handle not existing alias data, more careful refcounting

  1. … 2 more files in changeset.
- use NsfCommandPreserve/NsfCommandRelease for tcd->aliasCmd as well. In case of epoched cmdPointers, refetch the cmd and it client data.

  1. … 2 more files in changeset.
- nsf.c: changed handling of cmdPtrs in callstack content. * we use now explicit reference counting using NsfCommandPreserve/NsfCommandRelease * as a consequence, we do not need the following functions Nsf_DeleteCommandFromToken() and CallStackClearCmdReferences() any more. * the flag NSF_CSC_OBJECT_ACTIVATED is not needed anymore and was removed

- removed a small memory leak when a destroy method of an object o

deletes its grandparents namespace, containing also this class of o

(and its methods). Significantly eased by the change above.

  1. … 4 more files in changeset.
- new function Nsf_NextHashEntry() simular Tcl_NextHashEntry(), but handles triggered hash entry deletions - fixed reference count in AliasDeleteObjectReference()

  1. … 3 more files in changeset.
- use same test for class cleanup in NSDeleteChildren as well

- use a different test for detecting already deleted items
