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

  1. … 10 more files in changeset.
- first steps towards DTRACE support

  1. … 5 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.
- added profile support for nsf::proc

  1. … 3 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

  1. … 8 more files in changeset.
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.
- nsfStack.c: provide hook to obtain callers information in profiling code

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.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.
- minor cleanup

- fixed potential access to freed memory (actually when checking if namespace was removed by Tcl); found this problem when compiling Tcl with SYSTEM_MALLOC (own modified version of tclThreadAlloc.c) - fixed memory leak (namespace names and structures)

  1. … 4 more files in changeset.
- defined UNUSED macro to get more checking on unused arguments

  1. … 3 more files in changeset.
- removed leftover -public flag in nsf::method - general cleanup: removed unused arguments

  1. … 7 more files in changeset.
- removed unneded functions: NsfComputePrecedence(), NsfComputeDependents(), Nsf_SetVar2Ex(), NsfOSetInstVar(), Nsf_ObjGetVar2(), NsfOGetInstVar(), qNsfCreateObject() - removed unneeded external declarations: NsfClassListAdd() NsfClassListFree() - make extern declarations explicit - grouped most extern definitions together - improved documentation - moved variable declarations to inner scopes - removed warning from cppcheck()

  1. … 9 more files in changeset.
- follow Tcl nameing convention (uppercase functions)

  1. … 3 more files in changeset.
- perform relation handling in objectparameters outside of object-frame

  1. … 2 more files in changeset.
- show "unwind unstacked entry" message appear only when debug level>0 - removed fixed TODO entries

  1. … 2 more files in changeset.
- activated SKIP_LAMBDA in nsfCallstack. As a consequence, we disallow resolving self/my ... from tcl-proc frames (use uplevel if necessary, avoid "namespace eval")

  1. … 3 more files in changeset.
- impoved NsColonVarResolver, made some assumptions explicit

  1. … 2 more files in changeset.
- fixed scoping issue, when "-volatile" was used for object creation - added regression test for interaction between filters and function resolver (and volatile) - reactivated new volatile test in destroy.test - undone temporary fixes for volatile in serializer and nx.tcl

  1. … 5 more files in changeset.
- changed CallStackGetActiveProcFrame() to return also CMETHD frames This allows to execute :volatile in a initcmd and to delete the object at its end. As a consequence, code like [CopyHandler new -volatile] copy [::nsf::self] $newName has to be changed to CopyHandler new { :copy [:uplevel ::nsf::self] [uplevel set newName] :destroy } - renamed CallStackUseActiveFrames() to CallStackUseActiveFrame() and ctx->framesSaved to ctx->frameSaved to reflect implementation

  1. … 5 more files in changeset.
- removed debugging from CscFinish when compiled without DEVELOPMENT

  1. … 3 more files in changeset.
- fixed bug when calling aliased proc not via method interface - fixed bug when calling destroy in initcmd

  1. … 2 more files in changeset.
- added a few more small optimization. - code-generator: don't call argument parser, when no arguments are specified

  1. … 6 more files in changeset.
- removed bug-alert from nx.tcl (wrong false-positives for compiled locals in slots) - added a few small optimization. nsf appears to run on the shootout benchmark the same speed like a year ago (which much less functionality)

  1. … 5 more files in changeset.
- make exit more silent, when not debugging

- made handling of unstacked entries optional by defining macro CHECK_ACTIVATION_COUNTS) - added macro NSF_DEVELOPMENT for toplevel handling if NDEBUG and CHECK_ACTIVATION_COUNTS - cleanup of method-modifiers.tcl - updated next migration guide

  1. … 6 more files in changeset.
- added handling of unstacked csc entries (removed all DEBUG warnings).

  1. … 10 more files in changeset.
