- alias reform: instead of calling first an alias with a stack frame followed by the dispatched of the aliased cmd, resolve aliases internally in dispatch. This has the advantage that we do not have to ignore the "transparent" stack frame in some sitations, and we have much less problems with the names of the aliased cmds (e.g. objects) in the introspection methods. Additionally, several problem cases disappeared from the regression test cases. In addition, the new approach is faster. - eliminating obsolete flag NSF_CSC_CALL_IS_TRANSPARENT

  1. … 9 more files in changeset.
- fixed bug with recursive aliases - extended regression test

  1. … 2 more files in changeset.
- make sure to use "XOTcl 2.0" instead of just XOTcl in "package req" to avoid confusions due to beta state - remove more obsolete and untested files

  1. … 56 more files in changeset.
- rename "info method handle /methodName/" into "info method registrationhandle /methodName/" - rename "info method origin /methodName/" into "info method definitionhandle /methodName/" - added "info method origin" to return the target of an alias (or empty)

  1. … 19 more files in changeset.
- further cleanup and extend regression test

nsf.c: * fixed recration of object alias with a alias to a different cmd

  1. … 3 more files in changeset.
- nsf.c: * minor cleanup * added regression tests

  1. … 2 more files in changeset.
- nx.tcl * renamed "attribute" to "property" * renamed "defaultAttributeCallProtection" to "defaultPropertyCallProtection" * renamed "nx::Attribute" to ""nx::VariableSlot" * renamed "BootStrapAttributeSlot" to "BootStrapVariableSlot" * renamed "createBootstrapAttributeSlots" to "createBootstrapVariableSlots" * removed method attributes * implemented old attributes definition in xotcl2 as method "parameter"

  1. … 32 more files in changeset.
- test.tcl: * don't export Test per-default * define Test as nx::Test * make Test parameter count 1 the default, change to higher numbers where needed

  1. … 15 more files in changeset.
* Hopefully the last big naming change: Instead of writing "C class-object method foo {} {...}" one can write now "C class method foo {} {...}" to define a class method named "foo" for class "C". This naming change became possible by defining XOTcl's "class" (and "superclass") as object parameter only. To change a class of an object o, one has to use "o configure -class NEWCLASS". The term "object-class" looks alien to language beginners, the term "class" is much more straightforward. Changing classes or superclasses is seldomly used by typicall application programs.

For already existing nx scripts, changing "object-class" into

class should be straightforward.

* various documentation updates (migration guide, nx tutorial)

- 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.
- 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.
- 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.
- added regression test

  1. … 1 more file 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.
- nx.tcl: * full rewrite of slot machinerie, much simpler structure * relation handling via parameter aliases instread of pseudo converter * mixinclass SlotOptimizer removed * new class BootStrapAttributeSlot

- ConvertToRelation() and handling of parametertype "relation"

- Make CompiledColonVarFetch() more robust in case of

half initialized objects (create vartable on the fly if needed)

- allow empty parameter options in parameter parser

- removed nsf::parametersfromslots (became simple, part of objectparameter now)

- removed hardcoded objectparameter (attributes, volatile and noinit)

- updated regression test

  1. … 8 more files in changeset.
