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.
- first steps towards DTRACE support

  1. … 5 more files in changeset.
- configure: added flag --with-profile to enable profiling support

  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.
- reanimated NSF_PROFILE

  1. … 5 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.
- nsf.c: fixed a nasty bug within namespace deletion, when a deletion of one tcl cmd caused implicit deletions of other cmds in the same namespace. The classical idiom for looking over hash tables with Tcl_GetHashValue() and Tcl_NextHashEntry(hSrch) can lead to crashes (and has different behavior depending on the number of buckets). - added regression test

  1. … 3 more files in changeset.
- removed c-implementation of method vwait, it was replaced by "vwait :varName". We had to allow flag TCL_GLOBAL_ONLY in InterpColonVarResolver(), since Tcl vwait implementation calls it with that flag. - added a scripted implementation for vwait in xotcl2

  1. … 8 more files in changeset.
- improve documentation

- added methodtype "nsfproc" to "... info methods ...", to be used with namespace qualified names - return "nsfproc" as methodtype for nsfprocs - refactored InvokeShadowedProc() - some minor code cleanup and improved documentation

  1. … 5 more files in changeset.
- added flag: NSF_WITH_VALUE_WARNINGS

  1. … 1 more file in changeset.
- made assertion code optional - added and renamed additions compile flags NSF_WITH_INHERIT_NAMESPACES NSF_WITH_OS_RESOLVER NSF_WITH_ASSERTIONS

  1. … 3 more files in changeset.
- added preprocessor swithch INHERIT_NAMESPACES_TO_CHILD_OBJECTS

  1. … 1 more file in changeset.
- made error messages more consistent - improved error messages for "returns" and "nsf::is" (omit parameter name)

  1. … 11 more files in changeset.
- fixed bug with required last object parameter without provided value - extended regression test

  1. … 4 more files in changeset.
- keep DEVELOPMENT macro

- configure.in: removed --with-tclinclude option, since it appears to be included in tcl.m4 (since a while). Many thanks to Victor Guerra for noticing it.

  1. … 3 more files in changeset.
- added new contains definition based on "apply" instead of "namespace eval". Main intention is to replace SKIP_LEVELS by SKIP_LAMBDA - added functionality to use ":attribute contains:method,nosetter" - added regression test for contains and attributes of type method

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

  1. … 3 more files in changeset.
- remved debugging from NsfCleanupObject when compiled without DEVELOPMENT

  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.
- implemented exported command ::nsf::self as fast conveniance replacement for "::nsf::current object".

  1. … 8 more files in changeset.
- follow current Tcl vonvention for patchlevel var: - changed name of ::nsf::patchlevel to ::nsf::patchLevel - changed content ::nsf::patchLevel from eg .0 to full number including release details

- fixed bug in ::variable with colon-prefixed name

(shadowCommands does not help, see above)

- removed traces of Nsf_VariableObjCmd()

- extended regression test

  1. … 7 more files in changeset.
- 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.
- removed DISPATCH_TRACE - moved return-value checking into ObjectDispatchFinalize() - perform invariants checking after cmd execution, not additionally before - commented dispatch machinery

  1. … 3 more files in changeset.
- removed TCL85STACK_TRACE - renamed cscPtr->callType to cscPtr->flags, since this is now more appropriate - some more minor cleanup

  1. … 4 more files in changeset.
- save snapshot; refactoring in order to ease NRE development with unified method and dipatch exit. - named debugging cmds __db_* - new cmd __db_run_assertions to perform checking of the internal state

  1. … 7 more files in changeset.
- some refactoring for making code structure more sane for NRE (but not done yet)

  1. … 4 more files in changeset.
- make coloncmd are NRE-enabled - make every internal method invokation (NsfCallMethodWithArgs() and CallMethod()) NRE-configurable - use "Nsf" prefix for global vars to avoid potential conflicts - minimal support for sane-NRE patch - failed so far to make my NRE-enabled - new compile-flag for tracing: NRE_CALLBACK_TRACE - extended regression test (added test for 8.6 apply) - renamed tests/coroutines.tcl to tests/tcl86.tcl

  1. … 7 more files in changeset.
