"/obj/ info - configure" is actually a convenience method to allow to - write o1 info configure instead of o1 info lookup configure - syntax +2008-12-01 + * Correct deletion of user-metaclasses: Deletion of + user-metaclasses could lead to undestroyable objects, since the + instances of the user-metaclasses were reclassed to + ::xotcl::Object instead of ::xotcl::Class. + * extend regression test for such situations - package nx::class-method: - - convenience package similar to nx::plain-object-method - - allow for usage "C class method ..." in addition to "C object - method". - - made warnings configurable via nx::configure - class-method-warning on|off - - completed coverage and test cases +2008-11-02 + * Release of XOTcl 1.6.2 - package nx::plain-object-method: - - made warnings configurable via nx::configure - plain-object-method-warning on|off - - completed coverage and test cases +2008-11-01 + * added command ::xotcl::finalize -2013-05-30 Gustaf Neumann + This command has the only purpose to delete all objects and classes + of an interpreter in a multi-threaded environment at a safe time. - nsf.c - - fixed potential infinite loop in pattern matching for - precedence lists - - cget: make error message closer to tcl conventions - - extended regression test + Background: when XOTcl is used in a threaded environment such as + for example in AOLserver, one has to take care that the deletion + of objects and classes happens in a safe environment, where the + XOTcl destructors (destroy methods) are still able to + run. Without ::xotcl::finalize the deletion happens in + Tcl_FinalizeThread(), after thread cleanup (where e.g. the + thread local storage is freed). This can lead to memory leaks in + AOLserver, which allocates e.g. some structures on demand, but + since this happens after cleanup, it will leak. A simple ns_log + in a destructor might lead to this problem. The solution is to + call ::xotcl::finalize in the "delete trace" in AOLserver (as it + happens in OpenACS). -2013-05-29 Gustaf Neumann + Note, that ::xotcl::finalize is not intended for application programs. - - adapt to object methods - - prevent default value checking, when it is determined by a command - - completed coverage if plain-object-method.tcl - - provide warnings via plain-object-method.tcl via "nsf::log warn ..." + * some code cleanup -2013-05-28 Gustaf Neumann +2008-10-17 - - renamed initblock parameter from __initcmd to __initblock - - renamed nsf::configure parameter from "keepinitcmds" to - "keepcmds" + * handle nonposargs in method "copy" properly - - saving "keepcmds" in an associative array named - "__cmd(/parameternName)" to allow saving of multiple - parmeters with less name clash danger (when application - stays away from variables stating with double underscore) + * extend regression test for copy - nx.tcl: - - removed "info is .." since it might raise more questions - than it solves + * added " mixinof -closure ?pattern?" + Query the objects for which is used as a per-object-mixin + (directly or indirectly) - - changed enumeration values for "-source" in - "info lookup methods" - "info lookup slots" - "info methods" - "info slots" - from - "all|application|baseclasses" - to - "all|application|system" - for consistency with "nsf::my" and "nsf::dispatch" which uses - "-system" as well + * extended regression test for mixinof -2013-05-26 Gustaf Neumann + * updated documentation - Traits: - - changed from traits-as-objects to traits-as-classes.

The trailing argument of the - configure parameters (used e.g. for scripted object/class - definitions) is now of type "cmd".

Prior to that fix, the intermediate (and - inactive) CMETHOD frame wrapping configure() calls caused - [current methodpath]s to report empty string elements. Added - some test cases. - - nsf.c / ObjectDispatch(), DispatchUnknownMethod(): When testing - objects as alias parameter targets, I found cases when the - default (C-level) unknown handler was invoked upon. The result - was an unknown message which reported the delegator object as - "unknown" method! This was due to injecting the delegator - object into the argument vector at position 0, subsequently - used by the C-level unknown handler. First, I tried to make the - C-level unknown handler aware of the ensemble call context (by - funneling through the CSC and frame flags) but this turned out - to be complicated to achieve this simple task. As an - alternative, I suggest the following patch: The first argument - in unknown calls is treated as a list, and dependening on the - call context (ensemble vs. non-ensemble) contains all the - necessary call data. For ensemble methods, it is the delegator - object, the entire method path (as returned by [current - methodpath]), and the actual unknown selector. The default - C-level handler, treating the call info as list, resorts to - reporting the last element of the list which is always the - unknown selector.

-	- nsf.tcl / ::nsf::mixin: The proc implementation used "mixin" rather

-
-
-	- Adjusted for multiplicity types
-	- Added new templates: attributemethod.html.tmpl is responsible
-	  for rendering accessor/mutators for attribute slots,
-	  object.html.tmpl for objects.
-	- I now render attribute slots both in their object parameter
-	  view & a method view. Furthermore, I distinguish between the
-	  incremental vs. ordinary interface (as requested).
-	- Fixed div boxing scheme (again)
-	- Adjusted various places (method.html.tmpl, submethod.html.tmpl)
-	  to display the status marks (more to come)
-	- Streamlined the method views, introducing Type and Protection
-	  sections
-	- Started adopting the /obj/ prefix in parameter listings
-	- Made the @use mechanism working again (under validation). Once
-	  tiny bit needs to be fixed: The upward propagation of status
-	  messages if @use is in place.
-	- Removed the cause for redundant validation calls by traversing
-	  the entity hierarchy only once.
-	- Added nx-specific tracers (to distinguish between ensemble and
-	  slot objects, ...) For now, they work fine, but are tangled
-	  with non-nx tracing. This needs refactoring.
-	- Added another nx-specific tracer which tackles the issue of the
-	  __resolve_method_path helper. While quite cumbersome and
-	  coupling nxdoc to many internal design decisions of nx, it
-	  turns any change in nx.tcl unnecessary.
-	- Fixed ::nx::doc::handleinfo to deal with objects as methods
-	  (the case for intermediate ensemble objects).
-	- Added ::nsf::setter support
-	- Fixed the validation support for submethod structures.

-
-	Accomplishments:
-	- Completed a first version of the sandboxed (partial) evaluation
-	  of Tcl source artifacts (packages, script files, C extensions)
-	  based on a dedicated child/slave interp environment: see
-	  ::nx::doc::Sandbox; the test suite and the test documentation
-	  builts run on it.
-	- Based on this infrastructure, we can now generate a snapshot of
-	  a program's structure to be documented (and contrast it to the
-	  explicitly documented structure).
-	- Added simplistic css sprites for visualising the doc entity
-	  status (extra, missing, mismatch, complete); see also
-	  library/lib/doc-assets/status.svg and
-	  library/lib/doc-assets/status.png
-	- The entity status is printed optionally along with the print
-	  name of an entity
-	- Added switch-like parts to represent properties of doc
-	  entities: @deprecated, @stashed, @c-implemented, @syshook. The
-	  implementation and use of ::nx::doc::SwitchAttribute should be
-	  reviewed after having figured out how to proceed using
-	  "switching" objparams.
-	- I provide a multi-property dispatcher as doc-syntactic sugar and for
-	  mere convenience: @property
-	Various:
-	- Corrected some div-boxing mess in the templates
-	- Added a filtered helper to process entity collections
-	- Made the mixin layer infrastructure more symmetric (a revoke
-	  operation).
-	- Added tracers for ::nsf::method and ::nsf::alias (remains to be
-	  completed)
-	- Renamed ::nx::doc to ::nx::processor and turned it into another
-	 mixin layer to trace the doc entity creation in e.g. readin()
-	- Companion (*.nxd) files: Revised the handling of companion
-	 files. Temporarily moved generic/nsf.nxd in the top-level
-	 directory. We need to find a permanent place as its location is
-	 currently derived from the location of the shared extension. A
-	 candidate is doc/ but this is not linked to the shared extension
-	 location at all.
-	- processor.readin() now returns a collection of entities created
-	 during its execution.
-	- Improved robustedness and orthogonality: destroy hooks; the
-	 tag-dispatcher can now handle empty comment lines; when placing NSF
-	 object tracer, we now use the freshly added introspection of an
-	 object system's method aliases.

-
-
-	 - Conditionally disabling redefine protection (based on the
-	  presence of a global var ::nsf::bootstrap) failed due to the
-	  result flag not being set to TCL_OK in this case.
-	- Adding a (redundant) [package provide nsf /version/] to the ifneeded
-	script in nsf's pkgIndex.tcl. Background: [load] is only executed
-	once (leaving aside [unload]) for a given interp. Hence, the
-	initialization function and its Tcl_PkgProvide() call are only
-	performed once. A subsequent [package forget] and [package req] barfs
-	because the package version information is removed internally upon
-	[package forget]:
-	 "attempt to provide package nsf 2.0.0 failed: no version of package
-	 nsf provided"
-	 The Tcl docu provides hints on this requirement (for C
-	 extensions); see man for [package provide]:
-	 "[package provide] is typically invoked once as part of an ifneeded
-	 script, and again by the package itself when it is finally loaded."
-	 Note that most C-extension packages (sqlite, tdom) do not meet this
-	 requirement.

-	- provide a more explicit way to handle resourcing after a "package
-	  forget" in the info methods (similar to Stefan's suggestion).
-
-
-	- keep DEVELOPMENT macro
-
-
-	- changed relation handling by evaluating the relationcmd in the
-	  parent context to keep evaluation order.
-	- extend introspection "nsf::configure objectsystem": the command
-	  returns now all system methods in the syntax of
-	  nsf::createobjectsystem
-	- "nsf::createobjectsystem" creates now a warning when an
-	  existing objectsystem is redefined and ignores the new
-	  definition attempt. This was done with the purpose to allow
-	  "package forget nx; package require nx"
-	- Allow overwriting of redefine protected method during bootstrap
-	  to ease "package forget nx; package require nx"
-	- forward had just "-objscope", no general "-frame
-	  method|object". Since forwarder have client data, they always
-	  push a method frame. So, the situation is different to
-	  nsd::alias and ::nsf::dispatch. Therefore, the flag "-objscope"
-	  was renamed to "-objectframe" to provide better consistency
-	  with "-frame object"
-	- fixed bug, where error handling of invalid options in
-	  ForwardProcessOptions() could lead to a crash
-	- return forwardoption "-earlybinding" via instrospection
-	- extended regression test

-	Squashed commit of the following:
-	commit 370f47d26099dd8cda4125de67048461edb797a9
-	Author: ssoberni 
-	Date: Thu Nov 4 10:56:11 2010 +0100
-	 Due to recent changes in InterpColonVarResolver() to handle the
-	 slow-path execution the byte-compiled [variable], an unwanted
-	   interaction between ::nsf::setter, *certain* per-object namespaces,
-	 and the ColonCmd()-based invocation of setter methods became
-	 visible. In short: Given a pre-existing Tcl namespace and the
-	 colon-prefixed call specification to a setter method,
-	 InterpColonVarResolver() handles the var resolution request issued by
-	 the setter method (or SetInstVar(), more precisely). In a
-	 colon-prefixed call, the Tcl_Obj carrying the setter method name and
-	 used to lookup the object variable contains the ":". At the same time,
-	 the per-object namespace causes the TCL_NAMESPACE_ONLY flag to be set
-	 which causes InterpColonVarResolver() to pass on the request. In this
-	 setting, we end up with colon-prefixed object variables! See
-	 tests/parameter.test for an explanatory test case. For the time being,
-	 I fixed this by preserving and using the original, colon-free Tcl_Obj
-	 indicating the variable name in the client data structure of the
-	 settercmd.

-	  non-compiled script execution interacting.
-	- Added a first sample test (which documents the motivating issue
-	  observed for AOLserver vs. NaviServer)
-	- Further testing and documenting are pending
-
-2010-10-18  ssoberni  
-
-
-	- Added a missing squared brace in the serializer
-	- Made sure that alias definitions are properly serialized: Starting at
-	a cutoff of 2 did not reflect the change of access modifiers being
-	reported in the alias definition string. Therefore, the cutoff
-	referred to the alias method itself, leading to an erroneous
-	::nsf::alias statement being generated.
-
-2010-10-16  Gustaf A. Neumann  
-
-
-	- make sure not to return CompiledLocal vars from
-	  InterpColonVarResolver() when TCL_NAMESPACE_ONLY is requested.
-	- delegate always from InterpColonVarResolver() to other resolvers,
-	  when TCL_NAMESPACE_ONLY is requested.
-
-2010-10-15  Gustaf A. Neumann  
-
-
-	- provided parametersyntax definitions for XOTcl 2.0 similar to nx for
-	  all methods without a spec (e.g. fur builtin Tcl cmds, forwarders)
-
-
-	- 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
-
-2010-10-15  ssoberni  
-
-
-	- Corrected the link generation for autocomplete/search entries
-	  in case of @use chaining and made them location-independent
-	- Removed an superfluous div-closing tag in class.html.tmpl
-	- Refactored the backend code for the auto-completion search box,
-	  separating the concerns of rendering the JS array of hashes and
-	  serialising entities into a dict representation. The latter
-	  allows to discriminate entity-specific rendering behaviour
-	  (together with the mixin layer facility).
-	- Added the entity type (its pretty name) to the search results
-	  presented to the doc user.
-	- Removed the unwanted "::"s from @project and @package names.
-
-2010-10-14  ssoberni  
-
-
-	 - Switch to print_name() for rendering entity names for the
-	  search box
-	- Fixed the @parameter generation in method.html.tmpl
-	- @glossary: Support for referencing glossary entries with
-	  certain formatting annotations: @gls (minor letters only), @Gls
-	  (title), @glspl (plural), @Glspl (title plural), ... Added
-	  explicit acronym rendering (long and short forms): @acrfirst,
-	  @acr; fixing an id-generation issue for @glossary entities
-	- Completed the first round of amending nx.nxd with @glossary
-	  entries and references.
-	- I got rid of curly braces ("{", "}") as marker symbols
-	  ("{{...}}", "{{{ ... }}}") for formatting fragments of comment
-	  blocks. They proofed sufficiently hairy due to their heavily
-	  loaded meaning for the Tcl parser (the unclosed brace issue in
-	  Tcl comment blocks, the list-like processing in our comment
-	  block parser, ...). Instead, I introduced <<...>> for link-like
-	  elements (anchors, glossary references) and MediaWiki-like
-	  '''...''' blockmarkers for code listings. Thanks to Victor
-	  Guerra for reviewing and discussing this concrete-syntactic
-	  design decision.
-	- Increased the robustness of line-by-line parsing for comment
-	  blocks. Within the comment block parser, we operate on comment
-	  lines as Tcl lists (lindex, lassign, ...). While convenient
-	  from a processing perspective, this risks limiting the degrees
-	  of freedom when writing comments (e.g., using tabs and spaces
-	  to indent inline, grouping words to form lists of lists, ...).
-	  By leveraging "args" argument processing through [apply] for
-	  line preprocessing, we balance the two requirements.
-	- Verified that @use works between objects and methods.
-	- Some cleanup in the mixin layer code
-	- Resolve interp-alias chains to entity class objects explicitly
-	- Adjusting the Container/Containable mechanism to apply only to
-	  part classes relevant to particular container entities.
-	- Fixing support for package rendering as top-level entities
-	  (e.g., in the leftbar menu)
-	- Providing the project object to all entities subject to
-	  template processing.
-	- Declaring some forwarders public explicitly (to reflect recent
-	  changes in the reach of default call protection)
-
-2010-10-12  Gustaf A. Neumann  
-
-
-	- 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
-
-2010-10-11  Gustaf A. Neumann  
-
-
-	- added handling of unstacked csc entries (removed all DEBUG warnings).
-
-2010-10-10  Gustaf A. Neumann  
-
-
-	- copied decls for objectMethod and classMethod as comments to
-	  nsf.c, fixed order
-	- documented a few functions
-
-
-	- use "nsf::configure debug" for value 1: compain about protected
-	  value >1: provide load messages for nx and xotcl
-	- unset unneeded variables in ::nx namespace
-
-
-	- fix requiredness of several info methods
-	- added "nsf::configure debug ?level?"
-
-2010-10-09  Gustaf A. Neumann  
-
-
-	- renamed some arguments of tcl interface to increase consistency
-	- make requiredness explicit for nsf::cmds
-	- introduce ::nsf::parametersyntax to provide syntax for
-	  potentially missing definitions

-	  (from relationslots)
-
-2010-10-08  Gustaf A. Neumann  
-
-
-	- replaced "-objscope" and "-nonleaf" by "-frame
-	  object|method|default" for nsf::alias and nsf::default
-	- added functionality for "-frame method" to nsf::dispatch
-	- made the order of argument in ::nsf::alias and method "alias"
-	  the same (always first the method, then "-frame ...")
-	- extened regression test
-
-2010-10-07  Gustaf A. Neumann  
-
-
-	- added support for aolserver (essentially Makefile +
-	  aol-xotcl.tcl)
-	- removed unneded content from serializer output
-
-
-	- regenerated content
-
-
-	- added expermimental code to avoid "variable :x" crash based on
-	shadowCommands, but this does not work, when varible is bytecompiled.
-	deactivated for now.
-
-
-	- added functionality to show enumerated values in "info
-	  parametersyntax"
-
-
-	- removed CheckAllInstances()
-
-
-	- fixed aliasing warning for gcc 4.4.4
-
-
-	- fixed one aliasing warning for gcc 4.4.4
-
-2010-10-06  Gustaf Neumann  
-
-
-	- iteration over TODO file
-	- removed obsolete entries from generic/nsf.decls und
-	  generic/nsfInt.decls
-	- removed NSF_CMD_NOT_FOUND
-
-2010-10-06  Gustaf A. Neumann  
-
-
-	- updated TODO
-
-
-	- cleanup aol-xotcl.tcl and document usage in aolserver and naviserver
-
-
-	- make pickier compiler happy
-
-
-	- keep track of defaultMethodCallProtection and
-	  defaultAttributeCallProtection in serailizer
-
-
-	- document usage
-
-
-	- align logic with nstrace for naviserver
-
-
-	- remove obsolete TK_LIB_SPEC
-
-
-	- Implemented built-in-converter for "baseclass" and "metaclass".
-	  Change in performance for this call. >8 times faster before:
-	  parameters/parametercheck.007: 19.49 mms, ::nsf::is baseclass C
-	  after: parameters/parametercheck.007: 2.32 mms, ::nsf::is
-	  baseclass C
-	- remove scripted definition of "baseclass" and "metaclass"
-
-
-	- call scripted converters without checking protection
-	- removed defaultMethodCallProtection from tests/parameters.tcl
-
-2010-10-05  Gustaf A. Neumann  
-
-
-	- fixed wording
-
-
-	- changed option -expand in "info methods" and "info lookup
-	  methods" into "-path" to associate with the method path
-	- changed method property name from "protected" to
-	  "call-protected"
-	- changed nx::defaultMethodProtection to
-	  nx::defaultMethodCallProtection
-	- nx::defaultAttributeProtection is used for scripted methods,
-	  forwarders and aliases
-	- added nx::defaultAttributeProtection, used for setter and attributes
-
-
-	- changed option -expand in "info methods" and "info lookup methods"
-	  into "-path" to associate with the method path
-
-
-	- cleanup of __resolve_method_path
-	- change TclShowStack into NsfShowStack() to avoid possible
-	    interference with the Tcl* namespace
-	- made the following function static to avoid pollution of the global
-	  link namespace: CompiledColonVarFree(), GetRegObject(), ParamGetType()
-
-
-	- Methodpaths can be used now in the definition of "method",
-	  "alias" and "forward." We do not support it for "setter" and
-	  "attribute", since these require a parameter spec, which does
-	  not have clear semantics for a method path.
-	- scripted definition of nx::Object.forward and nx::Class.forward
-
-2010-10-05  ssoberni  
-
-
-	 - Major refactoring based on a minimal Mixin Layer facility to
-	  modularise optional features (such as templating, documentation
-	  verification etc.) in layers of mixins to be applied to the
-	  entire entity hierarchy.
-	- Rewrote the html templating machinery in terms of a mixin
-	  layer: NxDocRenderer
-	- Used the new modularisation granularity to add
-	  @glossary-specific link rendering (following ideas from
-	  http://www.alistapart.com/articles/hattrick/)
-	- Completed glossary support and added acronym handling
-	- Added back references and ref counting for @glossary entries
-	  (to be displayed with the glossary lists)
-	- I added the short-cut lists for selected part types of @class
-	  entities, namely @class-method and @class-attribute.
-	- Fixed the rendering of methods and attributes for ascending
-	  alphabetical order.
-
-2010-10-05  Gustaf A. Neumann

-	- removed "info forward" from nx::Object and nx::Class (can be replaced
-	  by "info methods" and "info method")
-
-
-	- allow %method in forwarder.
-	- defined unknown methods as call-protected
-	- make __default_method_protection protected
-
-
-	- extended regression test for "current methodpath"
-
-

-	  object to make implementation more simple.
-	- simplified EnsembleObject.defaultcmd and EnsembleObject.unknown
-	  significantly, scripted support methods are removed.
-	- extended regression test
-
-
-	- nsf::current: new option "methodpath", returns the full name of
-	  an ensemble method starting from the ensemble root.
-	- documented functions in nfsStack.c
-	- removed obsolete CallStackGetFrame(), replaced by
-	  CallStackGetTopFrame()
-
-
-	- factored out ParamGetType() to obtain from a paramPtr a type
-	  string
-	- parametersyntax:
-	  * changed "... -x arg ..." into ".... -x value ..."
-	  * changed multiple values notation from "list" to "..."
-
-
-	- strip space from source files
-
-2010-10-04  Gustaf A. Neumann  
-
-
-	- "info method parametersyntax" returns now for all nonpos args
-	  the type instead of "arg" when possible (eg ..... ?-x object?
-	  ....)
-	- extended regression test
-
-
-	- provide full set of ensemble methods from EnsembleObject.unknown
-	(i.e. from all classes along the precedence order. It was necessary
-	to pass calling object as first argument)
-
-
-	- "info lookup methods": order of non-pos parameters
-	  alphabetically
-	- added option "-expand" to "info lookup methods ". It collects
-	  ensemble methods along the precedence path
-	- added support for ensemble methods in "info lookup method"
-	- extended regression test
-
-2010-10-03  Gustaf A. Neumann  
-
-
-	- updated TODO
-
-
-	- make serializer more quiet
-
-
-	- nsf.c: use name "varTablePtr" instead of "varTable" when
-	  referring to the table
-	- new option "slotcontainer" for "methodproperty" to flag
-	  slotcontainer to make them easier to process in the serializer
-	  . don't report slot container in "info methods -expand"
-	- new function "::nx::isSlotContainer" to centralize checking for
-	  slotcontainers (used by serilaizer)
-	- support export of method ensembles in serializer
-
-2010-10-02  Gustaf A. Neumann  
-
-
-	- new option "-expand" for "obj|class info methods" to return
-	  compound names (i.e. it lists the full ensemble names) Example:
-	  ::nx::Object info methods -expand "*filter*" returns filter
-	  {info filter guard} {info filter methods} {info lookup filter}
-	- allow ensemble names in nsf::methodproperty
-	- fix compound name lookups when aliases link to shared ensemble
-	  objects
-	- make objectName() NULL-safe
-	- fix option "-source application" when applied directly on
-	  base-classes
-	- extend regression test
-
-
-	- make test more quiet
-
-2010-10-01  Gustaf A. Neumann  
-
-
-	- serializer: experimental code to serialize submethods
-
-
-	- "info method submethods": return all submethods, independent from
-	  protection
-
-
-	- fix potential crash in ::nx::Object info method definition
-	  ::nsf::methods::object::instvar
-
-
-	- fix typo
-
-
-	- slots:
-	  * change name "initcmd" of "experimental slot features" to
-	  "defaultcmd" to avoid naming conflict the the initcmd executed
-	  at the initilization of a slot object (effects XOTcl as well)
-	  * make defaultcmd/valuecmd/valuechangedcmd working for nx
-	  (absence of trace method)
-	  * provide error message, when default/defaultcmd/valuecmd are
-	  used non-exclusively
-	  * make sure to init per-object slots after copy operations
-	  * make nx::Attribute.destroy more definsive
-	  * extend test cases
-
-
-	- nsf: added flag NSF_DESTROY_CALLED_SUCCESS in addition to
-	NSF_DESTROY_CALLED to distinguish between attempted and successful
-	destroy method invocations (important for cleanup)
-
-
-	- update with decls generated from tcl 8.5.9
-
-2010-09-30  Gustaf A. Neumann  
-
-
-	- serializer:
-	  * added support for ordering on aliases referencing other
-	  objects/classes
-	  * provide shared version of the method warn via alias and removed
-	  direct output to stderr
-
-
-	- XOTcl 2: allow info slots for objects as well
-
-
-	- reduce size of output of serializer
-	- make nx::Object.serialize public
-
-
-	- filter more unneeded files from tar archive
-
-
-	- extended the apply regression test

-2010-09-29  ssoberni  
-
-
-	 - Minor revision of template files (to unify the naming of
-	  markup labels)
-	- Removed occurrences of old [:let]
-	- Use href() helper method to generate fragments of per-document
-	  ("local") anchor names
-	- Introduced more pretty_name and pretty_plurals for part
-	  attributes
-	- Make filename generation aware of the property of being a part
-	  or partof entity!
-	- Revised the documentation of [::nsf::current] slightly
-	- Adding setter ([:!let]) and getter ([:!get]) to the templating
-	  language, both being aware of @use chains.
-	- Refactored the resolution behaviour for part levels, relative
-	  to a given entity, into a helper
-	  StructuredEntity->owned_parts(). Based on this helper, the
-	  navigation structures can be rendered on common grounds (e.g.,
-	  drop-down search box, menus in th eleft bar)
-	- Adding the attributes "pretty_name" and "pretty_plural" to part
-	  attribute slots (used for rendering section names in the nav
-	  menu etc.).
-	- Adding a helper method href() to render the href attribute
-	  values of entity anchors (links, menu items, ...)
-	- Unified the rendering of the selection data used by the
-	  drop-down box for the various entity_types, again, using the
-	  owned_parts() helper
-	- Refactored the generation of navigation menu in the left bar
-	  into a proper template: leftbar.html.tmpl
-	- Reflect recent naming changes (e.g., predefined.tcl -> nsf.tcl)
-	- Adding support for documentation inheritance; first, fixed
-	  @command support for it
-	- Refactored the upward resolution of partof entities into a
-	  central and shared facility (Entity->get_upward_path())
-	- Adjusting for changes in introspection interface
-	  (info.callable() -> info.lookup())
-	- Adding a first aliasing (@use) mechanism. Remains to be tested
-	  properly, though it works sufficiently for the known use cases.
-	- Adding some safety checks to Tag->find()
-	- Refactoring context->parse@tag to use the Tag->find() helper
-	  (now shared between tag creation and link resolution)
-	- Tag path normalisation (expanding shortcuts, balanced list
-	  check, ...) went into Tag->normalise().
-	- Changed the [:link ...] mechansism ({{@someTag ...}}) to
-	  operate on the new tag notation. Added support for sub-method
-	  and sub-command link rendering (looks sufficient for the
-	  moment).
-	- Changed the existing *.nxd companions to match these notational
-	  modifications.
-
-2010-09-29  Gustaf A. Neumann  
-
-
-	- handle call-protection in serializer (works again with OpenACS /
-	  naviserver)

-
-
-	- declare publically used methods as public

-
-2010-09-24  Gustaf A. Neumann  
-
-
-	- removed TCL85STACK_TRACE
-	- renamed cscPtr->callType to cscPtr->flags, since this is now
-	  more appropriate
-	- some more minor cleanup
-
-
-	- changed debug command __db_yield (unporable between various 8.6b*
-	  version) into __db_show_stack
-
-
-	- changed internal method name requireNamespace to "require_namespace"
-
-
-	- added tcl-cool as an additional sample-object-system for nsf
-
-

-
-
-	- some refactoring for making code structure more sane for NRE (but not
-	  done yet)
-
-2010-09-22  Gustaf A. Neumann  
-
-
-	- removed third level from libary/pkgIndex.tcl (not needed)
-
-
-	- 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

-
-2010-09-21  Gustaf A. Neumann  
-
-
-	- make comparison slightly simpler (C style)
-
-
-	- Big internal changes for handling nre-enabled procs in more
-	situations. Handles now all nx regression tests, but fails in
-	testx.xotcl (just nre-enabled)
-
-2010-09-21  ssoberni  
-
-
-	Fixed the bitwise flag comparison in ProtectionMatches() which failed
-	to yield a boolean result. This resulted in unanticipated [obj info
-	methods -callprotection] behaviour, with the -callprotection filter
-	seemingly being ignored. Added some tests to tests/info-method.tcl.
-
-2010-09-20  ssoberni  
-
-
-	Make library/pkgIndex.tcl traversing three directory levels (instead of
-	just 2). This is necessary to catch the packages and
-	library/xotcl/library. As a symptom, xocomm.test failed. This was
-	because it was picking up comm packages in the install, rather than the
-	source tree which did not reflect the changes in the nested object
-	dispatches: [my connection foo] -> [[self]::connection foo]
-
-2010-09-18  Gustaf A. Neumann

-	  naming changes.
-
-2010-09-08  Gustaf A. Neumann  
-
-
-	- BRO continues:
-	- overworked function prototype definitions in nsf.c
-	- renamed some static definitions on the way to follow Tcl conventions
-	  (start with a capital character)
-
-2010-09-08  ssoberni  
-
-
-	 - Added two new templates: method.html.tmpl and
-	  submethod.html.tmpl
-	- Generalised the support for sub-commands and sub-methods,
-	  including a shortcut notation for tag lines.
-	- Adding the special handling of initcmd blocks of attribute
-	  slots: They are processed as @param specifications of their
-	  owning (class) object. In a next step, I will limit this
-	  special handling to the first comment block only, while
-	  subsequent ones are evaluated in the context of the slot object
-	  itself.
-	- Fixed an issue with cleaning up the processing-related mixin
-	  classes in the CommentBlockParser: As the nested notation of
-	  doc entities can conflict with relation slot forwarders
-	  (*::info::mixin vs. *::info mixin ), I revert to
-	  using ::nsf::relation directly.
-	- Fixed the default namespace resolution (still needs some
-	  review, once all use cases are figured out!) Changed nx and nsf
-	  documentation accordingly.
-	- Add first doc text for Object->info() and its sub-methods (for
-	  testing purposes, merely)
-	- Added an initial implementation for parsing level support. By
-	  introducing skipping axes into the tag notation (e.g.,
-	  @..param), we can now differentiate between different scopes of
-	  applications for tags. This has a number of advantages: a)
-	  processing becomes more efficient (skip-level annotated tags
-	  can be identified early), b) we do not have maintain different
-	  tag labels for different parsing levels (e.g., @child-object
-	  vs. @object), ...
-	- Parsing levels have to be maintained within the documentation
-	  processor and provided to the comment block parsers at work.
-	  This still has to be accomplished.
-	- Adapted the naming scheme for qualifier tags (for now). Instead
-	  of "child" scopes, we coerce the entity names using namespace
-	  delimiters (this fits nested objects nicely)
-	- Changed the resolution behaviour for dotted tag labels:
-	  Intermediate nodes (i.e., entities) are not allocated anymore,
-	  on the fly. Rather, it is a pure id resolution, except from the
-	  leaf element which is effectively initialised as a
-	  documentation entity. This has major implications: It requires
-	  partof entities to exist prior to any part entity. However, the
-	  id resolution work can later be reused when introducing the new
-	  tag notations into the link block markers in the templating
-	  engine (avoiding zombie and widely undescribed doc entities).
-	- Started shifting id generation into part attributes (for the
-	  time being). Probably I will do so permanently to avoid the
-	  complexity in the various new() factories for doc entity types.
-	- Adjusted the tests accordings and added many more on the
-	  navigatable tag notation.
-	- Renamed EntityClass and PartClass into Tag and PartTag. The
-	  meta-class names so better reflect their purpose as entity
-	  factory classes, based on the tag notation scheme. Added a
-	  QualifierTag meta-class which marks tags (@class, @object,
-	  @command) which impose extra requirements when not being part
-	  of another entity (in particular, default namespace
-	  resolution). If not part of another entity, they represent
-	    *qualifying* language constructs, i.e. language constructs
-	  which help identify other elements (command -> subcommand,
-	  object -> nested object or method).
-	- Started harmonising the entity class hierarchy (not ready cooked
-	yet): Entity < StructuredEntity < ContainerEntity < @project <
-	@method < @package < PartEntity < @object (@param) < @class < @command
-	The most important change is that all entities (entity instances) can
-	become parts, however, only a single entity class (@param) is critical
-	about it.

-	  default namespaces can be specified.
-	- Added a distinct @class entity family.
-	- @project and @package can now trace the creation of specified

-
-	- experimental method-property "class-only": this allows to make
-	  object save against per-object mixins of meta-classes. the flag
-	  is only used in the mixin-resolver
-	- used for the time being in nx only for Class.info, but would apply as
-	  well for methods defined on both Object and Class.

-
-	- changed __invalidateobjectparameter from a method of class to
-	  framework primitiv ::nsf::invalidateobjectparameter

-
-
-	Fixed some more [info callable] occurrences
-
-2010-08-20  Gustaf A. Neumann  
-
-
-	- removed XOTCL_METHODTYPE_OBJECT from XOTCL_METHODTYPE_BUILTIN
-	- default methodtype returns now everything, which is a true
-	  method (except objects)
-	- methodtype -all includes objects
-	- the object "slot" does not appear now in the method listing per
-	  default for classes having slots
-
-
-	- removed methods object-mixin and object-filter from the
-	  interface. (Caused some duplication of logic in the method
-	  "object") _ added option noforwarder to RelationSlots
-	- some minor cleanup
-
-2010-08-20  ssoberni  
-
-
-	- Accomplished major rewrite and cleanup of the comment block
-	  parser. The revised design allows us to express parsing states
-	  (context, description, part) as well as their substates
-	  reflecting the comment line processed (tag, text, space)
-	  directly. The design follows a METHODS-FOR-STATES strategy.
-	  Also, the parsing logic is now self-contained and is not
-	  interwoven with the class hierarchy documentation entities
-	  anymore (i.e., the former process() method of Entity and its
-	  subclasses).
-	- The modal/reactive design of the comment block parser has been
-	  streamlined: There is a CommentBlockParser class which acts as
-	  the event source. The actual parsing is achieved by the
-	  mixin-refined entity objects by reacting upon the parsing
-	  events (process, parse, next).
-	- Adjusted the tests in doc.tcl accordingly.
-	- Changed occurrences of [info callable] to reflect the latest changes.

-
-	- made slot optimizer more robust
-
-2010-08-19  Gustaf A. Neumann  
-
-
-	- checked saftey of Class.method, Class.alias, Class.setter,
-	  Class.forward
-	- made Class.filterguard, Class.mixinguard, Class.attribute
-	  robust against per-object mixins from meta-classes
-	- fixed mixin/filter delete methods with guarded operations
-	- extended regression test
-	- all methods defined on both, Object and Class are now safe in respect
-	  to per-object mixins with meta-classes
-
-
-	- made Class.info, Class.mixin, Class.filter robust against
-	  per-object mixins from meta-classes
-	- extended regression test
-
-
-	- changed "info method filter ...." into "info callable filter
-	  ..."
-	- fixed "o info callable method" in some cases with mixins
-	- extended regression test
-	- updated migration guide
-
-
-	- renamed "info method name ..." into "info method handle ...",
-	  since it returned already the handle
-	- renamed ListMethodName() to ListMethodHandle()
-	- changed output of "info callable -which ..." from definition to
-	  method handle
-	- renamed "info callable -which ..." into "info callable method
-	  ..."
-	- updated regression test to reflect the changes
-
-2010-08-18  Gustaf A. Neumann  
-
-
-	- removed method "filtersearch" from nx.tcl
-	- added "obj info method filter methodName" to nx
-	- updated xotcl.2 to use new filtersearch imprementation
-	- updated migration guide
-
-
-	- removed method "autoname" from nx.tcl
-	- added "method require autoname"
-	- added "method require exists"
-
-
-	- nsf: provided scripted support for "require/provide methods"
-	- nx: new method ":require namespace" ":require method" "require
-	  object method"
-	- added regression test method-require
-	- removed requireNamespace from nx.tcl (still exists in xotcl)
-	- replaced "requireNamespace" by "require namespace" in nx
-	  regression tests
-	- updated migration guide
-
-
-	- upgraded to TEA 3.9
-
-
-	- fixed typo
-
-2010-08-17  Gustaf A. Neumann  
-
-
-	- implemented return value checker (for scripted and
-	  c-implemented methods)
-	- additional methodproperty returns (for registering a return
-	  value checker)
-	- support for incrementally adding stuff to paramDefs (such as
-	  slotobj or return value)
-	- new c-function ParamDefsNew()
-	- added regression test for return value checker
-
-2010-08-16  Gustaf A. Neumann  
-
-
-	- commented out XOTCL_CMD_NOT_FOUND, since it seems to be
-	  obsolete by now
-	- extended regression test to avoid CallDirectly on dealloc (the last
-	  place, where XOTCL_CMD_NOT_FOUND was used)
-
-
-	- implemented parameter option "allowempty"
-	- extended regression test
-
-
-	- make one more instproc context explicit

-2010-08-13  Gustaf A. Neumann  
-
-
-	- sketch next migratin guide examples
-
-
-	- continue work on migration guide
-
-
-	- replaced several occurrences of "eval" in nx.tcl and xotcl2.tcl
-
-
-	- Implemented "interp alias" support for classes. In some cases.
-	  interp-aliased classes worked already without additional code,
-	  but e.g. in "... -superclass C ..." it failed. Without this
-	  feature, one could not reuse a class with a different
-	  namespace, unless it was explicitely "namespace exported" in
-	  the source. The problem was the implementation of
-	  "::nx::Attribute", which should not be exported in nx (most
-	  people do a "namespace import ::nx::*") because there is no
-	  need to do so, but ::xotcl::Attribute should reuse it
-	- without subclassing). .... However, we still seem to have a problem,
-	when the interp-aliased Class is exported and imported to a different
-	namespace.
-	- removed definition of slots from nx, changed regression tests
-	 examples to to ::attribute instead of -slots
-
-
-	- adjusted path in documentation system for nx/nx.tcl
-
-
-	- moved all exports of nsf to predefined.tcl
-	- made imports in xotcl2 and nx explicit
-
-2010-08-12  Gustaf A. Neumann  
-
-
-	- updated to TEA 3.8
-
-
-	- some updates
-
-
-	- made the "next scripting laguage" a own, loadable tcl package
-	  (currently named nx, name is subject of change)
-	- predefined.tcl is now pretty minimal.
-
-
-	- fix further pathnames
-
-
-	- refactor make file to better separate xotcl from the rest
-
-2010-08-11  Gustaf A. Neumann  
-
-
-	- changed more self/current
-
-
-	- added interp alias "nx::self" to "nx::core::current method"
-	- changed "current proc" into "current method" in scripts and tests
-
-
-	- Introduced $xotcl_target_doc_dir for generated xotcl
-	  documentation. Generate xotcl documentation in this directory.
-	- moved more (hopefully all) xotcl doc components into library/xotcl/doc
-
-2010-08-10  Gustaf A. Neumann  
-
-
-	- updated migration guide, added section for callstack
-	  introspection
-	- updated serializer for new names
-
-
-	- xotcl.c:
-	  * new function GetObjectFromNsName() to obtail object or class
-	  from a fully qualified namespace name used in method handles
-	  (such as e.g. ::nx::core::classes::X)
-	  * new function MethodHandleObj() to return a tcl_obj containing
-	  the methodhandle
-	  * removed obsolete method getFullProcQualifier()
-	  * info methods obtain now object and/or class from fully
-	  qualified method names (method handles) if possible
-	  * return message handles in "current next", "current filterreg"
-	  and "... info filter ... -order", which can be used in "info
-	  method .... " for obtaining more details.
-	  * change all occurrances of "self" in next regression tests to
-	  current.
-	- xotcl2.tcl
-	  * implemented "self" as a proc to provide extensibility and full
-	  backward compatibilty; this opens opportunity to replace now
-	  e.g. "self proc" by "current method", etc.
-	  * provide full compatibility for "self next", "self filterreg"
-	  and "... info filter ... -order", returning old-style multiword
-	  method handles (such as e.g. "::C instproc foo")
-	- changed "next" to current in documentation framework and templates
-
-
-	- iterated through doc.tcl-TODOs
-	- changed CheckVarName to allow array names like e.g. a(::b)
-	- extended regression test
-	- fixed serializer to handle subobjects of explicitely exported objects
-
-2010-08-09  Gustaf A. Neumann  
-

-	  doc, tests, apps, lib etc. and moved obvious content here.
-	- adjusted regression test and old documentation system to work with
-	  new structure
-
-
-	- added redefine-protected to the object template
-	- added methodtype to object template
-	- some documentation updates
-	- some indentation/spacing improvements on xotcl.c
-	- let ".... info method .... METHOD" return values, when METHOD
-	  contains namespace prefix. This can be used to obtain the
-	  parmeter definitions from nx::core
-	- get forward definition from the original command
-
-2010-08-07  Gustaf A. Neumann  
-
-
-	- added @properties and has_property to the documentation
-	  classes. Current primary purpose: define, which methods are
-	  internally-called
-	- added interanlly-called to the method object template
-
-2010-08-06  Gustaf A. Neumann  
-
-
-	- renamed mk_predefined.xotcl -> mk_predefined.tcl
-	- renamed predefined.xotcl -> predefined.tcl
-	- additional subcommand "info method parametersyntax
-	  " returns parameters in a syntax similar to the tcl
-	  man pages

-	  ::nx::core::signature(::nx::Object-method-forward)
-	  (experimental)
-	- fixed documentation system to work with actual version
-	- added undocumented methods for quality control in documentation
-	- added checks for documented, but unavailable methods in
-	  documentation

-
-2010-07-29  ssoberni  
-
-
-	- I created a first draft of the nx language manual, based on the new
-	next::doc facilities. It is still incomplete, but demonstrates the
-	use of next::doc for authoring code documentation.
-	 To re-create the language reference (which is not yet integrated into
-	 the build environment), run:
-	 ./nextsh tests/doc.xotcl
-	 You will then find an output directory "NextLanguageCore" in your
-	 /tmp/ directory.
-	- The next::doc comments which are sourced for generating the manual
-	 can be found in generic/gentclAPI.decls and
-	 generic/predefined.xotcl. I tried to add most comments to the
-	 former, as the complexity of the predefined script does not comfort
-	 documentation comments (and vice versa).
-	- Applied many fixes to the templates (based on the needs of the
-	 language reference)
-
-2010-07-29  Gustaf A. Neumann  
-
-
-	- migration guide overhaul
-
-
-	- define ensemble-like command for accessing instance variables

-
-
-	Adding the interim logo
-
-
-	- Added a placeholder logo image, to replace the YUI one for the
-	  time being
-	- Provided for giving some version information at either the project or
-	  package level
-
-
-	- Fixed search box and autocompletion support (for packages and
-	  objects)
-	- I allow for selecting/deselecting structural features set
-	  "private" ("deprecated" remains to be done)
-	- I added the generation of links between documentation entities based
-	on {{...}} markers. Any marker (code as well as links) can now be
-	used in both description and parts sections.
-
-2010-07-27  ssoberni  
-
-
-	- Adding basic support for subcommands (a @subcommand part type;
-	  formerly @variant)
-	- Introducing comment reuse and cross-linkage along the class
-	  hierarchy upwards ("subclass of ...", showing inherited
-	  attributes and methods; using a @superclass attribute)
-	- Amending the documentation of @param and @return with "type"
-	  information (checkoptions, constraints, defaults)
-	- Showing both per-class and per-object methods
-	- I now allow for inline- and out-of-line (block) code snippets
-	  in the description sections, based on wiki-like {{{...}}}
-	  marker annotation (same as in scaladoc2).
-	- Adding support for newline representations in description
-	  sections (for a more convenient formatting).
-	- Some bugfixes (e.g., @object-method did not work outside of an
-	  initcmd)
-	- Started refactoring the entity tracing procedure (moving from
-	  [namespace import] resolution to mixin-based creation tracing)

-2010-07-22  Gustaf Neumann  
-
-
-	- don't allow names with namespace separators or colon prefix in
-	  importvar/instvar
-	- provide error message, when method (proc scope) is not found
-	- fix array boundaries for looping on variables in
-	  importvar/instvar
-	- extended regression test
-
-2010-06-23  Gustaf A. Neumann  
-
-
-	- provide spacing in conditional assignments
-
-
-	- fix cleanup of subclasses of metaclasses, keeping metaclass property
-	  (thanks to Stefan for digging into this)
-
-2010-06-18  ssoberni  
-
-
-	 - Added a first set of documentation templates, based on the the
-	  TemplateData engine and the YUI doc styles available from
-	  http://yuilibrary.com/downloads/ (see
-	  library/lib/doc-assets/*.tmpl.html)
-	- Added a @project entity class, which will become the root
-	  concept in a documentation hierarchy. For now, it only serves
-	  for some auxiliary purposes when processing the doc templates.
-	- Continued documenting the next::doc package for testing purposes.
-
-2010-06-16  ssoberni  
-
-
-	 - I made sure that the existing HtmlRenderer infrastructure
-	  remains functional
-	- Added a simplistic templating machinery (see TemplateData), based on
-	cascading [subst] calls in per-object evals (assuming the nonleaf
-	mode) and a basic templating instruction set (i.e., "let", "for", as
-	well as "?" representing if-elseif-else blocks and "include" for
-	composing template fragments). This will help me to transpose the YUI
-	doc templates more easily (and split them up into template fragments).
-	Also, it will allow future documentation writers to provide custom
-	templates or modifications of existing ones. This was somehow inspired
-	by Kristoffer Lawson "templating engine" in his Spindle web framework,
-	which is solely based on Tcl namespaces, however.
-
-2010-06-14  ssoberni  
-
-
-	- Removed @attribute parts and realise them as @param parts which
-	  are parts of @object parts
-	- Renamed PartAttribute->get_part() to require_part()
-	- The line scanner now stores all comment lines as list by using
-	[split] at an early stage to improve the robustness when line strings
-	are fed to list-specific commands.
-
-
-	 - Introduced a PartClass meta-class which seconds Part and its
-	  subclasses (for a uniform id generation etc.)
-	- Removed the kludge around new_from_attribute(), there is now a
-	  canonical new().
-	- "scope" turned into a property of PartAttributes and, as such,
-	  of the association (slot) objects managing parts. this more
-	  closely resembles the idea of per-class and per-object
-	  interfaces. in turn, parts now contain a navigatable
-	  association to their managing part attributes (e.g., to resolve
-	  their scope).
-	- Adding some basic exception-catching infrastructure too better
-	  differentiate between error conditions (style violation,
-	  invalid tags, arbitrary errors emerging from the parsing
-	  machinery). Adjusting and extending the test suite.
-	- Simplified/generalised the parser's tag dispatcher; also, there
-	  is no a general @doc tag which allows to add documentation
-	  lines as tagged parts, rather than a distinct doc block
-	- Removed the tagged_entity mechanisms and per-tag forwards on
-	  EntityClass
-	- Documentation blocks may now contain intermediate space lines
-	  (by adding a space->text transition to the parsing spec).
-	- Adding basic support to trace script sources from [package req]
-	  calls, needs to be polished and refactored
-
-2010-06-05  Gustaf A. Neumann  
-
-
-	- provide explicit error message stating the "substdefault" is
-	  not allowed for setters
-	- don't add "substdefault" a second time, in case it was already
-	  used
-	- never add "substdefault" to methodopts
-	- extended regression test
-
-2010-05-31  ssoberni  
-
-
-	- Renamed EntityFactory to EntityClass
-	- Introduced PartAttribute for managing entity-part associations,
-	  they also protect against duplicate entries
-	- Added NextAttribute (though it should fuse with parameter
-	  entities in the end)
-	- Completed basic support for embedded (initcmd) and freestanding
-	  (script): This multi-stage processing introduces a precedence
-	  order between the commenting levels (script < initcmd < method
-	  bodies).
-	- Renamed most entity classes using their tag equivalent
-	  (@object, ...)
-	- Introduced offset feature for the comment line scanner (offsets
-	  are used to select embedded comment blocks, e.g., in initcmds
-	  or method bodies)
-	- Parsing of arbitrary scripts is now realised in a child interp
-	- Introduced qualified entity names (e.g., @attribute Bar#a1) and
-	  per-object scope (through a scope prefix in tags, e.g.,
-	  @object-method)
-	- Did some cleanup and extended the test suite
-

-2010-04-07  Gustaf A. Neumann  
-
-
-	- namespace changes: mostly due to marketing reasons, the naming of the
-	top-level namespace changed from "xotcl2" to "next". reasons: xotcl
-	is hard to pronounce for beginners, sounds like "exotic" (but who wants
-	to program in an exotic language) has a certain stigma of strange
-	namings (e.g. "instproc"), is seen as a precursor of tcloo, the
-	top-level namespace ::xotcl2:: is not very nice either, the separation
-	of framework and language is not clear.
-	 We have now:
-	 ::next (the new object system, former ::xotcl2)
-	 ::next::core (framework, primitives)
-	 ::xotcl (former xotcl1)
-	- "::xotcl::use" no longer needed, use Tcl standard mechanisms instead
-	(e.g. "package req next"; "package req XOTcl", "namespace import
-	::next*")

-2010-03-31  Gustaf Neumann  
-
-
-	- ::xotcl:.configure: added option "keepinitcmd" to flag, whether or
-	  not initcmds should be kept as instance variables
-
-
-	- remove unneeded attribute for method setter
-
-2010-03-29  Gustaf A. Neumann  
-
-
-	- Allow to speficy last arg of objectparameter to replace scripted init
-	block. The redefinition of objectparameter allows us to specify
-	whether no/some/classical/altered/additional arguments should be
-	allowed during object creation
-
-
-	- Handle cases, where objects/classes are created with the name of
-	preexiting namespaces. Cases, where pre-exisitng namespaces contained
-	classes/objects lead to problems, since xotcl did not see the
-	object/classes of the pre-exiting namespace as children of the new
-	object/class.
-
-2010-03-27  Gustaf A. Neumann  
-
-
-	- backport change from 2.0 to 1.6.6 concerning cylcic dependencies
-	  through namespace imported commands
-
-
-	- fix a potential ordering problem with cyclic dependencies created by
-	  namespace import commands
-
-2010-03-26  Gustaf Neumann  
-
-
-	- fix 64bit problem
-
-
-	- fixed 64bit problem

-
-
-	- xotcl 1.6.6: backport of memory fixes from xotcl 2.0
-
-
-	- add check for optional match arguments in tcl stub generator
-	- fix potential memory leaks all "definitely losts" from valgrind
-	  (except 24 bytes from Tcl_PkgRequire) gone
-
-2010-03-25  Gustaf A. Neumann  
-
-
-	- minor leak cleanup
-
-
-	- make valgrind + system malloc (instead of tcl malloc) run cleanly
-
-2010-03-23  Gustaf A. Neumann  
-
-
-	- replace hash-lookup in namespace in ObjectHasChildren() by
-	  pointer lookup to reduce namespace dependency.
-	- fix memcopy size
-
-2010-03-22  Gustaf A. Neumann  
-
-
-	- xotcl 1.6.6: one more cases for the packaging, where we want to load
-	  xotcl1 not 2
-
-
-	- xotcl 1.6.6: more cases for the regression test, where we want to
-	  load xotcl1 not 2
-
-
-	- xotcl 1.6.6: make sure to load always xotcl 1 versions when
-	  needed
-	- xotcl 1.6.6: make compilation clean when compiled with assertions on
-
-
-	- remove "buffer" from compiled var structures
-	- remove xotcl1 dependency from aol-tcl
-	- removed conditional var table creation by assertion
-	- make clean compile with assertions turned on
-
-2010-03-19  Gustaf A. Neumann  
-
-
-	- add verbosity for varname copying
-
-2010-03-15  Gustaf A. Neumann  
-
-
-	- rename CallStackPush() to CscInit()
-	- rename CallStackPop() to CscFinish()
-
-
-	- get rid of reminder of tcl 8.4 compatiblity and remove range of
-	ifdefs, such as PRE85, FORWARD_COMPATIBLE, TCL85STACK,
-	CANONICAL_ARGS, USE_COMPILED_VAR_RESOLVER
-
-
-	- removed EXPERIMENTAL_CMD_RESOLVER
-
-2010-03-15  Gustaf A. Neumann  
-
-
-	- handling of minimal object systems. For example, the following three
-	  command create an object system around ::object and ::class ...
-	 ::xotcl::createobjectsystem ::object ::class
-	 ::xotcl::alias ::class + ::xotcl::cmd::Class::create
-	 ::xotcl::alias ::object
-	- ::xotcl::cmd::Object::destroy
-	 ... where no internal message dispatch are used (e.g. no
-	 constructor "init", and where just two methods ("+" and "-")
-	 are used to create and destroy objects
-	- extended regression test
-
-2010-03-14  Gustaf A. Neumann  
-
-
-	- provide prefix for internally called methods to distinguish between
-	  methods called on objects or classes
-
-2010-03-13  Gustaf A. Neumann  
-
-
-	- eliminated XOTE___UNKNOWN
-	- renamed __unknown to requireobject
-
-
-	- eliminated XOTE_UNKNOWN
-
-
-	- eliminated XOTE_RESIDUALARGS
-
-
-	- renamed MethodObj() to XOTclMethodObj() (it is an exported
-	  symbol)
-	- eliminated XOTE_MOVE
-
-2010-03-13  Gustaf Neumann  
-
-
-	- replaced hard-coded method calls for XOTE_DEFAULTMETHOD, XOTE_INIT,
-	  XOTE_OBJECTPARAMETER with MethodObj()
-
-2010-03-12  Gustaf A. Neumann  
-
-
-	- created new functions: ObjectSystemFree(), ObjectSystemAdd(),
-	ObjectSystemsCheckSystemMethod(), ObjectSystemsCleanup(),
-	GetObjectSystem(), CallDirectly() for better separation of systems. We
-	keep track which essential system methods are defined and which which
-	methods are potentially overloaded.
-
-2010-03-11  Gustaf A. Neumann  
-
-
-	- move refcount fixing logic for exit from higher stackframes to new
-	  function: finalObjectDeletion()
-
-
-	- first part of allowing arbitrary named internally called methods.
-
-
-	- fix last issue, with freeing objects, when exit happens from higher
-	  stack frames
-
-2010-03-10  Gustaf A. Neumann  
-
-
-	- block call-stack deletes during XOTCL_EXITHANDLER_ON_SOFT_DESTROY;
-	however, this seems to create a small leak during exit (revant for
-	threads); so currently, debug still turned on
-
-2010-03-09  Gustaf A. Neumann  
-
-
-	- replace all CanInvokeDirectly() by InvokeMethodObj()
-
-
-	- remove some more obsolete RCS Ids
-	- call Tcl_Objs "Obj", not "Object"
-
-
-	- remove filter deactivation to a later point in time (should finally
-	  be before freeAllXOTclObjectsAndClasses())
-
-
-	- deactivate filters in finialize
-	- new method InvokeMethodObj() to replace finally CanInvokeDirectly()
-
-2010-03-08  Gustaf A. Neumann  
-
-
-	- one more change for handling expat dirs n version 1.6.6 (fallback to
-	  bundle)
-
-
-	- handling OBJECT-frames in CallStackPopAll() (for handling exit with
-	  active stack frames)
-
-
-	- one more change for handling expat dirs (fallback to bundle)
-
-
-	- call all truely essential methods directly if possible
-	(Object.destroy, Class.alloc, Class.dealloc, Class.create) The basics
-	of XOTcl can work now also in cases, when these are not defined as
-	methods.
-
-
-	- reduce verbosity
-
-
-	-minor cleanup
-
-
-	- make XOTcl_FrameDecls transparent (use variable declarations in
-	  place instead of the macro)
-	- fix variable shadowing bug in error handling (could cause crashes
-	  when initcmd lead to errors)
-
-
-	- define RecreateObject() for internal call via diect invocation
-	- doCleanup is just called by recreate; merge it into
-	XOTclCRecreateMethod. Is method cleanup necessary? is recreate not
-	sufficient?
-
-2010-03-07  Gustaf Neumann  
-
-
-	- call c-implemented methods directly for XOTE_RECREATE as well
-	  (otherwise, create is faster than recreate)
-
-2010-03-06  Gustaf A. Neumann  
-
-
-	- added stefan's expat library linking extension
-
-

-
-	- updating tcl.m4 in version 1.6.6 to the actual verison (TEA 3.7)
-
-
-	- removed redundant part from configure.in
-	- regenerated configure
-
-2010-03-05  Gustaf A. Neumann  
-
-
-	- call c-implemented methods directly, when this is safe
-	  (implemented for XOTE_ALLOC, XOTE_CLEANUP, XOTE_CONFIGURE,
-	  XOTE_CREATE, XOTE_DEALLOC); this improves create/destroy speed
-	  by up to 15%
-	- allocate namespaces for objects less eager
-	- make nameing more consistent (change newObj into newObject when
-	  variable is an xotcl object)
-
-2010-03-04  Gustaf A. Neumann  
-
-
-	- fixing "-parameter" with empty content
-	- more variable naming cleanup
-	- fix line breaking in serializer for "exportedObjects"

-	  and "class" pairs
-
-
-	- remove dependency from xotcl1 in handling of forwarders in
-	  method "copy"
-	- further cleanup using "CONST char *", improving on naming conventions
-
-
-	- further cleanup using "CONST char *"
-
-
-	- use "CONST char *" in generated interface and below
-
-2010-02-28  Gustaf A. Neumann  
-
-
-	- use "::xotcl::current" instead of "xotcl::self" in predefined
-
-
-	- defined "xotcl::current" as synonym for "::xotcl::self"
-	- new options for ::xotcl::current current object == current
-	  current method == current proc current callingmethod == current
-	  callingproc
-	- "self proc" and friends are for backward compatibility for
-	  xotcl1, "current method" and friends are for xotcl2
-	- namespace exported "::xotcl::current"
-
-
-	- minor cleanup (varresolution test and comment)

-
-2010-02-26  Gustaf Neumann  
-
-
-	- keep variables defined from an CMETHOD frame local to this
-	  frame (e.g. initcmd, -nonleaf option, ...); previously
-	  variables without xotcl resolver prefix were defined globally
-	- fix regression test according to previous item
-	- generalize nonXotclObjectProcFrame() and rename it to
-	  activeProcFrame()^
-
-2010-02-25  Gustaf A. Neumann  
-
-
-	- working towards KEEP_VARS_IN_CMETHOD_FRAME
-
-2010-02-24  Gustaf A. Neumann  
-
-
-	- requireNameSpace:
-	  * fix potental crash in requireNameSpace in objscoped methods by
-	  swapping all vartable references in objscopes on stack to the
-	  vartable in the namespace, when it is created
-	- extending regression test
-
-2010-02-23  Gustaf A. Neumann  
-
-
-	- fix for logdir parameter (introduced 10 mins ago)
-
-
-	- renaming of instance variable specific primitiva for more
-	  constistency with ::xotcl::importvar:
-	 ::xotcl::exists -> ::xotcl::existsvar
-	 ::xotcl::setinstvar -> ::xotcl::setvar
-
-
-	- removed XOTclCreateClass() and XOTclDeleteClass(); both are identical
-	  with XOTclCreateObject() and XOTclDeleteObject()
-
-
-	- removed obsolete ::xotcl::configure option "cacheinterface"
-
-
-	- added option "-nonleaf" for method alias
-	- added introspection (for "info method definition") for "alias ...
-	  -nonleaf ..."

-	  stack frames
-	- initcmd: skip parent-stack frame's objscope for initcmd
-	- changed hash-based lookup of children into a cmd-based lookup
-	- extended regression test
-
-
-	- call XOTclObject always "object" instead of "obj"
-
-2010-02-22  Gustaf A. Neumann  
-
-
-	- fixed namespace handling on stack for objects with namespaces
-	  (before, it was possible that a variable was created in an
-	  object's namespace without -objscope)
-	- as a consequence, ListChildren() had to be adjused, since it
-	  depended on the previous namespace handling on the stack
-	- fixed object sesolving in NsDotVarResolver() (before, it was
-	  possible that NsDotVarResolver could create variables in the
-	  wrong namespace)
-	- simplified NsDotVarResolver()
-	- more cleanup in name resolver
-	  * USE_DOT is gone
-	  * XOTclDotDotCmd() removed
-	  * improved performance of InterpCompiledDotVarResolver()
-	  * made LookupVarFromTable() obsolete and removed it
-	  * renamed DotVarResolver() and friends to ColonVarResolver() etc.
-	- extended regression test
-
-2010-02-21  Gustaf A. Neumann  
-
-
-	- replaced in predefined occurances of ::xotcl::is by
-	  ::xotcl::objectproperty
-
-
-	- renamed ::xotcl::valuecheck -> ::xotcl::parametercheck
-
-
-	- defined "info is" as alias of "::xotcl::objectproperty"
-
-2010-02-21  Gustaf A. Neumann  
-
-
-	- renamed old "xotcl::is" -> "xotcl::objectproperty"
-	- renamed old "xotcl::is2" -> "xotcl::is"
-	- we have now is tests for objects in ::xotcl::objectproperty
-	::xotcl::objectproperty $obj object ::xotcl::objectproperty $obj
-	class ::xotcl::objectproperty $obj baseclass ::xotcl::objectproperty
-	$obj metaclass ::xotcl::objectproperty $obj type XXXX
-	::xotcl::objectproperty $obj hasmixin XXXX
-	- "::xotcl::is" is the higher level command,
-	 supporting string contstraints "e.g. upper", user defined type checkers
-	and as well object properties (every parameter type supported for
-	object
-	 and method paameter). Examples:
-	 ::xotcl::is $obj object ?-type $type? ?-hasmixin $mixin?
-	 ::xotcl::is $cl class ?-type $type? ?-hasmixin $mixin?
-	 ::xotcl::is obj metaclass
-	 ::xotcl::is $num integer
-	 ::xotcl::is $string upper
-	- implemented 2nd level reference counting for paramObjType
-
-2010-02-20  Gustaf A. Neumann  
-
-
-	- Unified on c-level "info class-mixin-of" and "info
-	  object-mixin-of" to "info mixinof ?-scope all|object|class?
-	  ?-closure? ?pattern? The former "info class-mixin-of" is now
-	  "info mixinof -scope class"
-	- adapted xotcl1 layer for this change
-	- extended experimental ::xotcl::is2 to handle flags -type and
-	  -hasmixin ::xotcl::is2  object ?-type ? ?-hasmixin ?
-
-2010-02-19  Gustaf A. Neumann  
-
-
-	- experimental checking function ::xotcl::is2 implemented, which
-	generalizes between ::xotcl::is and ::xotcl::valuecheck (it is a
-	valuecheck -nocomplain with an ::xotcl::is syntax and switched
-	arguments)
-
-2010-02-19  Gustaf A. Neumann  
-
-
-	- support for method modifier "object", "protected" and "public" for
-	  method "attribute". One can use now e.g.
-	 Class create C {
-	 :attribute a
-	 :public attribute b
-	 :protected attribute c
-	 :object attribute A
-	 :public object attribute B
-	 :protected object attribute C
-	 }
-	 "protected" and "public" refers to the registered accessor functions
-
-2010-02-18  Gustaf A. Neumann  
-
-
-	- centralize fetching of tcl-obj-types in xotcl_init
-
-2010-02-17  Gustaf Neumann  
-
-

-
-
-	- removed the following classes and methods
-	::xotcl::Attribute->check_single_value
-	::xotcl::Attribute->check_multiple_values
-	::xotcl::Attribute->mk_type_checker class ::xotcl::Attribute::Nocheck
-
-
-	- added a version of the "attribute" method to predefined
-
-2010-02-15  Gustaf A. Neumann  
-
-
-	- new methods for MetaSlot to factor out common code: + slotName
-	  (to ease name-construction, care about slot container) +
-	  createFromParameterSyntax: essentially move from
-	  ::xotcl::Attribute to the meta class
-	- test environment: make sure to avoid confusions between the
-	  "namespace" method and command
-
-2010-02-14  Gustaf A. Neumann  
-
-
-	- experimental: allow to show built-in types provided that a)
-	  slot= is specified explicitely, and b) the specified slot is
-	  not the default slot. This should guarantee that we do not
-	  interfere with the predefined converters for the c-level
-	  interface.
-	- incremented ref count on results of all-level converter
-	- extended regression test
-
-2010-02-12  Gustaf A. Neumann  
-
-
-	- ::xotcl::valuecheck: moved "-nocomplain" to first position (similar
-	  to e.g. unset)
-
-
-	- fixed result resetting for user defined converters
-
-2010-02-11  Gustaf A. Neumann  
-
-
-	- implemented "info method definition|parameter|args $name" for
-	  settercmds (with parameter constraints)
-	- extended regression test
-
-
-	- fixed returned method name when setter was used on objects
-	- reduce verbosity
-
-
-	- added parameter "incremental" to ::xotcl::Attribute: when set,
-	  one can use "object paramname add|delete $value" etc.
-	- use setters with parameter constraints in slot optimizer
-	- as a consequence, setting attributes via slot names is about
-	  twice as fast as before, when parameter constraints are used.
-	- extended regression test
-
-
-	- added a "-nocomplain" option to ::xotcl::valuecheck
-	- changed semantic of ::xotcl::valuecheck: per default,
-	  valuecheck raises an error or returns true. If "-nocomplain" is
-	  used, valuecheck returns 0 or 1 like implemented befor this
-	  change
-	- extended regression test
-
-
-	- add comment to converter, make it less verbose
-
-
-	- removed duplciate error message in "hasmixin" converter
-	- fixed refcounting in converting user-types in case of errors
-	- extended regression test
-
-
-	- setterCmd(): Do not allow methodNames start with "-"
-	- setterCmd(): Do not allow defaults for setters
-	- extend regression test
-
-2010-02-10  Gustaf A. Neumann  
-
-
-	- Allowed parameter specification for setters. One can define now
-	  a setter with constraints like e.g. ::xotcl::setter o a:integer
-	  to define a setter named "a" for object "o" which has to be
-	  integer.
-	- Extended regression test
-	- Followed nameing conventions for several structures
-
-2010-02-09  Gustaf A. Neumann  
-
-
-	- bumped version number to 1.6.6
-
-
-	   * provide compatibility with 8.6b1
-
-
-	- fixed compilation for tcl 8.6b1
-
-
-	- fixed valuecheck in connection with modifying converters
-	- extended regression test
-
-2010-02-08  Gustaf A. Neumann  
-
-
-	- made error messages for failed conversions more consistent (note that
-	tcl does not provide the parameter name in the error message, but
-	user-defined converters do)
-
-
-	- clean up comments
-
-
-	- renamed "::xotcl::is ... mixin ..." to "::xotcl::is ... hasmixin ..."
-	  (affects parametertypes as well)
-
-
-	- move methodParameter checkers for "mixin", "baseclass" and
-	  "metaclass" to predefined.
-	- deactivated checkMethods in gentclAPI.decls and in xotcl.c
-
-
-	- provide error message for cases, where parameter options are not
-	  allowed (or ignored)
-
-
-	- fix counter initialization in ::xotcl::importvar
-	- register alternate "new" method in "contains" for xotcl2 and (if
-	  available) for xotcl1 objects
-
-2010-02-07  Gustaf A. Neumann  
-
-
-	- streamline quoting in regression test
-
-
-	- handle multivalued + values converted viaCmd converter the new output
-	  list is only built when needed via ArgumentCheckHelper()
-
-2010-02-05  Gustaf Neumann  
-
-
-	- added argument for converter to return the converted tcl_obj, which
-	should be passed on (currently only used for viaCmd); this way, we
-	could remove the kludge of querying the converter after the conversion
-	for special handling.
-
-
-	- treat currently unknown converters in valuecheckcmd as error
-	- fix the regression test from the last changes
-
-
-	- added parameter option slot= to pass slotobj to a certain
-	  parameter
-	- use slot option to keep relation between parameter and slot
-	- object parameter dispatch type checker on slot objects
-	- allow transformation via user-defined converter (can be use to
-	standardize parameter values) experimental implementation,
-	refcounting has to be looked in detail, maybe we need a different
-	interface for the converters
-
-2010-02-04  Gustaf Neumann  
-
-
-	- added error message when substdefault is specified without a
-	  default value
-	- extend regression test
-
-2010-02-03  Gustaf Neumann  
-
-
-	- predefined.xotcl: move toParameterSyntax and objectparameter to
-	  a position, where basic slot definitions are provided
-	- fixed default value setting in bootstrap code
-	- provide more precise error message in converter, when object
-	  type are used
-	- extend regression test
-
-
-	- get rid of convertToObjectOfType(), make convertToClass() and
-	  converterToObject() more general, accepting type constraints
-
-2010-02-02  Gustaf Neumann  
-
-
-	- support for all string constraints provided by "string is ...
-	  $value" in object and method parameters ("alum", "alpha", ...,
-	  "xdigit"). Technically, these types are tclobjs (using
-	  converter convertToTclobj) having pParm->converterArg set to
-	  the constraints.
-	- extended regression test
-
-2010-01-29  Gustaf A. Neumann  
-
-
-	- moved slot optimizer from ::xotcl::ObjectParameterSlot::Optimizer to
-	  ::xotcl::Attribute::Optimizer
-
-
-	- refactor Slot class hierarchie
-	- new methods in ObjectParameterSlot "toParameterSyntax" and
-	  "createFromParameterSyntax"
-	- some more cleanup
-	- removed legacy syntax for "-parmeters"
-
-2010-01-28  Gustaf A. Neumann  
-
-
-	- cleanup of legacy stuff in slot management.
-	  * merged InfoSlot and InterceptorSlot into RelationSlot
-	  * get rid of legacy "mixin set ...." command
-	- renamed "parameterSlot" into "methodParameterSlot" to avoid potential
-	  confusions
-
-
-	- define everything concerning basic slot setup in a single
-	  "namespace eval ::xotcl {...}"
-	- undefine ::xotcl::createBootstrapAttributeSlots after this block
-	- fix default DefaultSuperClass() with isMeta==1 in cases, where
-	  we are already at the root meta class
-	- use "-parameter" in xotcl1 instead of createBootstrapAttributeSlots
-
-2010-01-27  Gustaf Neumann  
-
-
-	- name parameterType -> parameterSlot
-	- use for now same parameterSlot for xotcl1 + 2
-	- disallow unknown types (otherwise interpreted as user-types) in
-	  valuecheck
-
-2010-01-26  Gustaf A. Neumann  
-
-
-	- allow syntax "object,type=::SomeClass" and
-	"class,type=::SomeMetaClass" (currently identical, we should as well
-	check for class/meta-class in case of "class,type=SomeClass")
-
-2010-01-25  Gustaf A. Neumann  
-
-
-	- remove unneeded push and pop operations in ListChildren() and
-	  ObjectHasChildren()
-
-
-	- name XOTclObjects always "object" instead of "obj" to avoid potential
-	  confusion with Tcl_Objs
-
-
-	- support for parameter spec of form "type=XXX" to denote that
-	  the parameter must be an object of the specified type (class;
-	  directly or indirectly)
-	- new built-in converter: convertToObjectOfType()
-	- keep parameterObj (source for conversion to XOTclParam) for
-	  making introspection less work. However, this is only used for
-	  XOTclParams generated via ParamParse().
-	- extending regression test
-
-2010-01-24  Gustaf A. Neumann  
-
-

-	  (including user defined types)
-	- new Tcl_ObjType "xotclParam"
-
-2010-01-23  Gustaf A. Neumann  
-
-
-	- checking multivalued types in "-parameters" by using argument
-	  checker
-	- some cleanup
-	- extend regression test
-
-
-	- added "multivalued" to parameter options

-	- test utility: changed "?" to return error msg in case of error
-
-
-	- don't run multiple queries in "??"
-	- fixed last changes to regression test as usual
-
-2010-01-22  Gustaf A. Neumann  
-

-	- use ::xotcl::forward in Slot constructor (instead of dispatch)
-	- checking methods on slots for single- and multivalues slots
-	  (can be optimized)
-	- extended regression test
-
-2010-01-21  Gustaf Neumann  
-
-
-	- added instance variable arg for interfacing with parameter
-	  interface. "arg" acts like a clientdata for type converter
-	- added multiple parameter options handling to method "parameter"
-	  to obtain similar functionality from object parameters as from
-	  method parameters
-	- added conveniance method "??" to test to indicated test that
-	  should fail with an error
-	- added severy type converters to achieve same object type
-	  checking as in ::xotcl::is (these are currently in the
-	  regression test, should move finally into predefined.xotcl)

-
-2010-01-19  Gustaf A. Neumann  
-
-
-	- making methodDefinitions NULL terminated
-	- passing optional arg to user-defined argument converter
-	- refuse to redefine type converters for a single parameter
-	- adding regression test for parameters
-
-2010-01-15  Gustaf A. Neumann  
-
-
-	- experimental change of resolver name prefix char from dot to single
-	  colon
-
-2010-01-14  Gustaf A. Neumann  
-
-
-	- extended migration guide
-	- defined eval in predefined via "-nonleaf", used at various
-	  places
-	- added "info mixinof ?-scope all|object|class? ?pattern?",
-	  dropped "object-mixin-of" and "class-mixin-on" from registerd

-	- extended regression test
-	- xotcl1: make "-volatile" invoked via unknown behave correctly
-
-2010-01-11  Gustaf A. Neumann  
-
-
-	- keep orignial objc/objc in call stack context such that
-	  next/self args works with canonical args (allow e.g. different
-	  order of nonpos args in a next)

-	- Serializer: fix syntax in exportMethods
-	- Serializer: provide limited support for exporting aliases for xotcl1
-	  objects
-
-2010-01-09  Gustaf A. Neumann  
-
-
-	- NsDotVarResolver: don't create variables on CMETHOD frames when their
-	  names do not start with a "."
-	- general overhaul of XOTcl_PushFrame()XOTcl_PopFrame():
-	 new functions:
-	   * XOTcl_PushFrameCsc()/XOTcl_PopFrameCsc(): for CMETHOD fames
-	   * XOTcl_PushFrameObj()/XOTcl_PopFrameObj(): for OBJECT frames
-	 (objscope)
-	- preallocate obj->vartable in XOTcl_PushFrameObj() to
-	 avoid situations where to non-existing vartable is created
-	 on demand at different places (e.g. on stack and in
-	 var resolver)
-	- caller of convertToRelationtype(): make sure that last argument
-	 keeping the result is large enough to held pointer (in case of
-	 sizeof(void) != sizeof(int)
-
-2010-01-08  Gustaf A. Neumann  
-
-
-	- use uplevel in slot add/delete to evalute in calling namespace
-	  (for not fully qualified object names)
-	- determine namespace in test method "?" to allow its execution
-	  in an "namespace eval"
-	- added regression tests
-
-
-	- extend regression test
-
-
-	- make sure to have an xotcl frame pushed, when byte-code-compiler is
-	invoked. This is necessary for providing the context for dotCmd
-	resolvers
-
-
-	- improved naming of resolvers: use InterpDot*Resolver and
-	  NsDot*Resolver for interp wide and namespace specific resolvers
-	- added possibility to escape the call of commands starting with a dot
-	  from method bodies by prefixing with a second dot.
-
-
-	- make allocation sizes for dynamically allocated
-	  parameterContexts consistent between alloc and realloc
-	- added sanity check in getAllClassMixinsOf() It seems as it would be
-	possible with __defaultSupeclass to define a class which has itself
-	als a subclass. Just a quick fix, we have investigate more on this.
-
-2010-01-07  Gustaf A. Neumann  
-
-
-	- serializer: move checking of the requested objects to be
-	  exported to the invocation of "Serializer all"
-	- replace "namespace import ::xotcl::*" by "xotcl::use xotcl1"
-
-
-	- improved comments
-
-2010-01-06  Gustaf A. Neumann  
-
-
-	- added option "objectsystems" to ::xotcl::configure to obtain
-	  the currently defined object systems
-	- added option "baseclass" to ::xotcl::is to check, whether a
-	  class is a baseclass of an object system (root class or root
-	  meta-class of object system)
-	- changed result of "... info methods -methodtype scripted" to
-	  return only truely scripted methods (no aliases)
-	- some more cleanup in regression tests
-	- first version of serializer for xotcl1 + xotcl2
-
-2010-01-05  Gustaf A. Neumann  
-
-
-	- modernize test a little: all local definitions of proc "?" are
-	  gone.
-	- added interface to test: "Test parameter count SOMEVALUE" to
-	  specify conveniently e.g. the number of tests the be executed
-	- add XOTCL_CM_NO_UNKNOWN to dispatch of defaultmethod
-
-
-	- added "info method" to migration guide
-
-
-	- added option "-application" to "info callable" to omit methods
-	  from base classes
-	- extended regression test
-	- changed naming of methodtype "system" to "builtin"
-	- added "info methods" to migration guide
-
-
-	- xotcl.c: removed all names starting with "inst" (exception: instvar)
-
-
-	- added option "arg=.." to parameter options; this argument can
-	  be passed to converter; used currently for "type=relation" to
-	  flag, that the relation type is different from the parameter
-	  name
-	- extended "objectparameter" to handle such cases
-	- removed relationtypes "mixin", "filter", "instfilter" and "instmixin"
-	  since not needed due to converterArg
-
-
-	- removed all unreferenced entries from XOTE_*
-	  - regrouped XOTE_* for easier comprehension
-	  - used XOTE_* on more occations
-	- used XOTclCallCommand() for calling Tcl "format" and "interp"
-
-
-	- removed XOTclInstVar from the C-level API. todo: add all xotcl*cmds
-	  to C api, including importvar
-
-
-	- changed resultss of "filtersearch" and "self next" to new
-	  naming Caveat: for xotcl1, there is no mapping for the names to
-	  the old style in "self next" and "self filterreg"
-	- backwards compatible mapping of filterseach in xotcl1
-
-2010-01-04  Gustaf A. Neumann  
-
-
-	- removed dependency on proc/instproc in copy/move. code is now
-	  independet of class system
-
-
-	- allow invovation of fully qualified method names (determined via ...
-	  info method name ...)
-
-
-	- moved cmd flags into xotclInt.h
-	- added missing prototype
-
-
-	- added interface definitions for generated tcl commands to xotcl.c
-
-2010-01-04  Gustaf A. Neumann  
-
-
-	- added experimental flag for alias "-noleaf" to force a stack frame to
-	be written (e.g. necessary for "next"). makes only sense for aliases
-	to c-implemented cmds
-	- fix inconsistent behaviour of dotVarResolver
-	 "o eval {set .x 1}" was setting var ".x" instead of "x"
-	 The problem was due to a interaction between
-	 the namespace varResolver() and the DotVarResolver()
-	- fix for DotCmdResolver during compilation of a proc by Tcl.
-	- extended regression text
-	- found 2 potential bugs (not fixed yet)
-
-2010-01-04  Gustaf A. Neumann  
-
-
-	- moved "-per-object" consequently immediately after obj in the
-	following commands : ::xotcl::alias, ::xotcl::methodproperty,
-	::xotcl::setter to achiev conformance with ::xotcl::forward and
-	::xotcl::method
-
-2010-01-03  Gustaf A. Neumann  
-
-
-	- reduce verbosity
-
-
-	- added ::xotcl::forward as cmd instead of method now, all
-	method-defining-methods (alias, method, forward, setter) are defined
-	as cmds (this should make life of serializer easier)
-
-
-	- added ::xotcl::method as cmd instead of methods object-method and
-	  class-method
-
-
-	- added ::xotcl::exists as cmd
-
-
-	- minor refactoring
-
-
-	- made some more xotcl2 methods protected (no big need to call these
-	  from different objects): unknown, uplevel, upvar
-
-2010-01-03  Gustaf A. Neumann  
-
-
-	- changed assertions: old (xotcl1) interface: 3 methods + 3 info
-	  methods
-	  *  check Options
-	  *  info check
-	  *  invar Conditions
-	  *  info invar
-	  *  instinvar Conditions
-	  *  info instinvar
-	 new (xotcl2) interface: 1 cmd (similar to ::xotcl::relation)
-	 ::xotcl::assertion check|object-invar|class-invar ?arg?
-	- added emulation for xotcl1
-	- deleted namespecific C macros:
-	isInfoString, isInstinvarString, isInvarString, isInstprocString,
-	isProcString
-
-2010-01-02  Gustaf A. Neumann  
-
-
-	- added method "eval" on ::xotcl2::Object
-	- used "o eval {....}" as generic method to apply commands/methods to
-	  other objects
-
-
-	- change and rename cmd instvar ::xotcl::instvar -object someObject
-	newVar into ::xotcl::importvar someObject newVar Rationale of change:
-	only needed in xotcl2 for importing variables from different objects
-
-
-	- handle HAVE_UINTPTR_T like HAVE_INTPTR_T
-	- use ::xotcl::setinstvar instead of ::xotcl::setinstvar in serializer
-
-
-	- use INT2PTR and PTR2INT macros in generated stubs
-
-
-	- update to TEA 3.7 (from TEAD 3.5)
-	- use of INT2PTR to avoid warnings about different sizes on 64bit
-	  architectures
-	- defined HAVE_INTPTR_T as a macro to make definition of INT2PTR working
-
-2010-01-01  Gustaf A. Neumann  
-
-
-	- changed level of headings
-
-
-	- added headings for parameter sections
-
-
-	- first skeleton of migration guide
-
-
-	- renamed "ClassName info instmixinof ?-closure? ?pattern?" into
-	  "ClassName info class-mixin-of ?-closure? ?pattern?"
-	- renamed "ClassName info mixinof ?-closure? ?pattern?" into
-	  "ClassName info object-mixin-of ?-closure? ?pattern?"
-	- added emulation "ClassName info instmixinof|mixinof" for xotcl1
-
-
-	- add minor comment
-
-
-	- reactivated XOTclErrInProc()
-
-
-	- get rid of rst->deallocCalled (not needed due to reference
-	  counting on xotcl objects)
-	- reduce verbosity
-
-
-	- added existence test for slot extractor (needed for 8.5.8)
-	- added refcounting CallStackDoDestroy() to ensure existance of
-	  object until end of function
-	- make sure to call PrimitiveDestroy() before
-	  DeleteCommandFromToken(), otherwise e.g. unset traces on this
-	  object cannot be executed
-	- regression test works again
-
-2009-12-31  Gustaf A. Neumann  
-
-
-	- added refounting in ObjectDispatch() to make sure, obj survives until
-	  the end of the function
-
-
-	- comment manual call to DoDealloc() in case the method has failed
-
-
-	- handle change in tcl 8.5.8:
-	  http://tcl.cvs.sourceforge.net/viewvc/tcl/tcl/generic/tclObj.c?sortby=date&r1=1.139.2.1&r2=1.139.2.2&pathrev=core-8-5-branch in xotcl:
-	  * when e.g. the parent namespace is deleted with a "namespace
-	  delete", the change above causes, the no xotcl methods could be
-	  resolved (and called) anymore.
-	  * therefore, e.g. a "C dealloc c1" did not work, since dealloc
-	  passes c1 via tcl_obj, and the tcl_obj is as well converted to
-	  an xotcl object via Tcl_GetCommandFromObj(), which fails as
-	  well.
-	- to bypass this problem, xotcl has now a C-function DoDealloc(),
-	  which is called, when this situation is detected.
-	- some more cases, where xotcl could reference already freed
-	  memory were fixed (thanks to enable-symbols=mem)
-	- as collateral damage, parts of the regression test don't work
-	  currently
-
-2009-12-30  Gustaf A. Neumann  
-
-
-	- space changes
-
-
-	- made naming more consisent
-	- alway initialize parse context properly
-
-2009-12-29  Gustaf A. Neumann  
-
-
-	- updated tutorial further
-
-
-	- updated first part of tutorial to xotcl2 syntax
-	- fixed examples in tutorial
-	- added soccerClub2.xotcl
-
-
-	- fix example in the tutorial
-
-
-	- new subcommand "... info method body ..." to avoid to relay on syntax
-	  of "info method definition" in xotcl1 compatibility
-
-
-	- removed -per-object from ::xotcl::relation
-	- removed -per-object from methods "mixinguard" and "filterguard"
-	- removed -per-object from methods "alias" and "method"

-
-
-	- call __UNKNOWN with XOTCL_CM_NO_PROTECT (don't complain when it is
-	  protected)
-
-
-	- added " object filter" and " object mixin"
-	- use explicit "(object|class)-(mixin|filter)" relations in
-	  ::xotcl::relation
-	- removed "-per-object" from all user-level relation commands
-	  (::xotcl::relation has still "-per-object"), but it is not
-	  needed anymore
-	- register slots "object-mixin" and "object-filter" for conveniance to
-	allow object-filter and object-mixins via configuration via object
-	parameter
-
-
-	- turned "setter" method into a command "::xotcl::setter" with
-	  the same interface like "::xotcl::alias"
-	- removed flag -per-object from XOTclCForwardMethod
-	- require "object" to be followed directly by either method defining
-	command or info, etc. (use "public object method" instead of "object
-	public method")

-2009-12-26  Gustaf A. Neumann  
-
-
-	- renamed method property "static" to "redefine-protected"
-
-
-	- removed "-protected" and "-public" from method defining methods

-	  "setter") return now the fully qualified method names
-	- extending 50 regression tests fpr method modifiers
-	- Make "unknown" for ::xotcl2::Class" to raise an error instead of
-	warning. Otherwise, protected class-level methods would create
-	objects with the name of protected methods. Other option: make calls to
-	protected methods raise an error, instead of calling "unknown"
-
-2009-12-23  Gustaf A. Neumann  
-
-
-	- return fully qualified name from method defining commands (part 1,
-	  "method")

-	- converted part of regression test
-
-
-	- minor refactoring to reflect changes in "info methods"
-
-2009-12-19  Gustaf A. Neumann  
-
-
-	- changed "info methods" (without defined, as defined in xotcl1)
-	  into "info callable"
-	- changed "info methods -defined" into "info methods"

-	- adding rests for behavior, when setting invalid mixins
-
-2009-12-17  Gustaf A. Neumann  
-

-
-
-	- minor cleanup of obsolete code
-
-
-	- removed deprecated calls from predefined and regression test
-
-
-	   * info params removed

-	  ?-per-object?  "
-	- added emulation for old "mixinguard" and "instmixinguard" in xotcl1
-	- xotcl1: defined "parametercmd" and "instparametercmd" in terms of
-	 alias instead of forward
-
-2009-12-15  Gustaf A. Neumann  
-
-
-	- forward: new option for handling flags syntax "%-SOMEFLAG ?insert?%"
-	The option checks the actual arguments, if they start with "-", it
-	compares it with the provided name. If it matches, the flag is consumed
-	and added at the provided position in the output list. If the flag does
-	not match, but "insert" is given with the value of 1, then the flag is
-	output as well. Note that the last feature is added for omitting double
-	inserts.
-	- due to the new forward option, the following important
-	 cases work now:
-	 - adding/deleting/... per-object mixins for classes via
-	 slot methods
-	 C mixin -per-object add M
-	 - adding per-object mixins for classes in short form
-	 C mixin -per-object M

-	  whether "per-object" should be passed via the forwarder
-	- new function MethodTypeMatches() for filtering on methodtypes
-	- provide faster lookup when pattern for info methods does not contain
-	  meta characters

-
-
-	- updated changelog
-
-2009-11-11  Gustaf A. Neumann  
-
-
-	- removed "-per-object" from " info alias"
-
-
-	- xotcl2: implemented " info -per-object subcmd" (moved
-	  "-per-object" in front of info, since it specifies, what kind
-	  of info is requested). As a consequence,
-	  XOTclObjInfoMethodMethod() works returns always object specific
-	  infos and XOTclClassInfoMethodMethod() class specific infos, no
-	  "-per-object" switch for the subcmd required.
-	- cleanup in other subcomds than "info method" and "info methods"
-	  required
-
-
-	- gentTclAPI: create every converter only once.
-
-2009-11-10  Gustaf A. Neumann  
-
-
-	- xotcl2: added "obj info method parameter name"

-	   * fixed proper list handling in AssertionList()
-	   * added tests for "info method" (infomethodtest.xotcl)
-	- changed method "alias" in xotcl2:

-	 we have now
-	 " setter "
-	 " setter ?-per-object? "
-	- added emulation for old "parametercmd" and "instparametercmd" in
-	  xotcl1
-	- method "instforward" is gone (for xotcl2),

-	  invokeCmdMethod()
-	- renamed DoCallProcCheck() into InvokeMethod()
-
-2009-08-17  Gustaf A. Neumann  
-
-
-	- removed XOTclCallStack definition and datastructures, when compiled
-	  with TCL85STACK
-	- CallStackPop(): when compiled with TCL85STACK,
-	 the function just initializes a given call stack content;
-	 allocation based on C-Stack
-	- some function cleanup and minor optimizations
-
-2009-08-14  Gustaf A. Neumann  
-
-
-	- added option withRootClass to ComputePrecedenceList();
-	- exclude rootClass in search for defaults (for the time being)
-	- implemented cmd ::xotcl::instvar
-
-2009-08-13  Gustaf A. Neumann  
-
-
-	- get rid of fakeNS
-	- minor simplification in XOTcl_PopFrame()
-
-
-	- Removed currentFramePtr (the pointer from the xotcl stack to the tcl
-	stack) from the call stack content. Now, all access to the call stack
-	content happens via the tcl85stack.
-	- For the time being, the xotcl stack is purely an allocation stack
-	(we still have to evaluate, where we should store the call stack
-	content efficiently:
-	some options: via alloca, on the c-stack, on the tcl stack, on an
-	allocation stack)
-
-
-	- new method CallStackPopAll() for making ExitHandler() independent
-	  from call stack structures
-
-
-	- implemented doCleanup() independent from stack structures
-	- some variable renaming
-
-
-	- renamed UndestroyObj() to CallStackMarkUndestroyed() and implemented
-	  it for tcl85stack
-
-
-	- get rid of CallStackIsDestroyed()
-
-
-	- move tcl85showStack(), nonXotclObjectProcFrame() and
-	  nextFrameOfType() to xotclStack*.c
-
-
-	- get rid of GetSelfProc()
-	- implemented XOTclNextMethod() for tcl85stack
-
-
-	- implemented XOTclForwardMethod () for tcl85stack
-
-
-	- return Tcl frame pointer as last arguments in
-	  CallStackGetFrame() and CallStackGetTopFrame()
-	- pass call stack content to GetSelfProc()
-	- some simplifications to avoid multipe stack searches
-	- implemented XOTclSelfSubCommand () for tcl85stack
-
-
-	- implemented FilterActiveOnObj() for tcl85stack
-
-
-	- pass conditionally XOTclCallStackContent to GuardCall() due to
-	  different stack lifetime
-	- CallStackPush() returns now callstack content
-	- implemented CallStackFindActiveFilter() for tcl85stack
-
-
-	- implemented computeLevelObj() for tcl85stack
-
-2009-08-12  Gustaf A. Neumann  
-
-
-	- implemented CallStackUseActiveFrames() for tcl85stack
-	- nonXotclObjectProcFrame returns now only active frames
-
-2009-08-11  Gustaf A. Neumann  
-
-
-	- implemented XOTclCallStackFindActiveFrame() for tcl85stack
-
-
-	- defined new (3rd) frame type FRAME_IS_XOTCL_CMETHOD for calling
-	  c-implemented methods (the same as FRAME_IS_XOTCL_OBJECT,
-	  except that it uses csc as clientData instead of only the xotcl
-	  object
-	- implemented XOTclCallStackFindLastInvocation() for tcl85stack
-
-
-	- pass call stack content explicitly to
-	  canonicalNonpositionalArgs to obtain active class or object
-	- fix two more regression test entries with canonical args (info
-	  body, order in info locals)
-	- canonical args passes now regression test (also in connection with
-	  tcl85stack)
-
-
-	- pass call stack content explicityl to XOTclNextMethod, which is
-	  used on one occurance outside the tcl callstack scope, such
-	  that CallStackGetTopFrame() gets the previous stack entry
-	- implemented CallStackGetTopFrame() for tcl85stack
-	- implemented CallStackGetObjectFrame() for tcl85stack
-
-2009-08-10  Gustaf A. Neumann  
-
-
-	- new function CallStackDestroyObject() to factor out xotcl stack
-	access Since tcl-stack-entries have a lightly different life-time
-	(pop is managed by tcl), we have as well slightly different life-times
-	of objects. One test in the test suite is deactivated for now, we will
-	see, if this turs out to become a problem as we proceed.
-
-
-	- new function CallStackClearCmdReferences() to factor out xotcl stack
-	  access
-
-
-	- moved stack procs into new files xotclStack.c and xotclStack85.c
-	- based CallStackGetFrame() in addition to GetSelfObj() to new
-	  stack structure, when TCL86STACK is defined
-	- fixed error and warning message for failed assertions to avoid access
-	  to the xotcl stack
-
-
-	- follow naming conventions for defines TCL85STACK_TRACE
-	- deactivate CANONICAL_ARGS for the time being
-
-
-	- Stefan implementation for args with canonical args
-	- canonicalNonpositionalArgs() receives explicit current xotcl object
-
-2009-08-09  Gustaf A. Neumann  
-
-
-	- remove debug output
-
-2009-08-09  Gustaf Neumann  
-
-
-	- rename variable "ns" (namespace pointer) to "nsPtr" for tcl naming
-	  compliance
-
-
-	- simplified callingNameSpace() significantly (works with and
-	  without TCL85STACK the same way)
-	- simplified GuardCall (removed argument push)
-	- removed unneeded functions, reduced tracing
-
-2009-08-09  Gustaf A. Neumann  
-
-
-	- snapshot 3
-	- first version passing regression test again
-
-2009-08-07  Gustaf A. Neumann  
-
-
-	more trace
-
-
-	- snapshot #2
-
-2009-08-06  Gustaf A. Neumann  
-
-
-	- starting to use tcl85 stack (when complied with TCL85STACK).
-	  Goal is to remove the own stack handling, when compiled with
-	  Tcl 8.5+ Introduced two frame types, FRAME_IS_XOTCL_METHOD and
-	  FRAME_IS_XOTCL_OBJECt
-	- Currently, only self is resolved this way from the Tcl stack.
-	- Currentlsy, just parts (e.g. testo.tcl) of the regression test work
-
-2009-08-05  Gustaf A. Neumann  
-
-
-	- updating changelog
-	- cleanup and documentation in xotcl.c
-
-
-	- cleanup of arguments in makeproc (Stefan Sobernig)
-
-
-	- finishing unset unspefied values in nonpos arg passing under
-	canonical args, when a nonposarg has no default, and the parameter is
-	not required, we have to unset the dummy default value. Since causes
-	some overhead, since unset is done via ::xotcl::unsetUnknownArgs
-
-2009-08-04  Gustaf A. Neumann  
-
-
-	commit snapshot
-
-2009-08-03  Gustaf Neumann  
-
-
-	- releasing dynamically allocated parse contexts
-	- tried to reduce overhead of method invocation when no nonposArgs are
-	  used, but failed, sind proc has neither flags not clientData
-
-2009-07-29  Gustaf Neumann  
-
-
-	- make ifdsize explicit (stubcode generator)
-	- new method parseContextInit(), will be used for variable sized
-	  interfaces (for nonpos arg parsing)
-
-2009-07-28  Gustaf Neumann  
-
-
-	- first implementation of canonical arguments
-
-2009-07-24  Gustaf Neumann  
-
-
-	removed duplicate line
-
-2009-07-07  Gustaf A. Neumann  
-
-
-	- based introspection for procs/instprocs on new argument definition
-	  structures
-	 - allowing type checkers also for positional arguments
-	 (for now only, when nonpos args are given as well; we have
-	 to think about using these either for all procs/instprocs,
-	 or only, when e.g. type checkers are used; we have to
-	 make more benchmarking to get a better foundation)
-	 - registered the following type checkers for procs/instprocs:
-	 switch, integer, boolean, object, class
-	 Example
-	 o proc bar {-enable:switch o:object c:class} {
-	 return "o=$o c=$c"
-	 }
-	 - generated interface for ::xotcl::configure; now 97 interfaces are
-	 generated; shortcoming for bool/int converter stubs: optional
-	 0-vaues are not recognized, so use tclobj for the time being
-	 - extended regression test
-
-2009-07-06  Gustaf A. Neumann  
-
-
-	 - parse non-pos-args for procs/instprocs into new argument
-	  definition structure
-	- using new parseObjv for calling procs and instproc when
-	  nonpos-args are used (invocation time went from 9.08ms to
-	  5.95ms)
-	- TODO: complete implementation for regression test, base
-	  introspection/copy etc. on new structures
-
-2009-07-05  Gustaf A. Neumann  
-
-
-	 - support for enumeration types in c-code generator
-	- use function pointer for type checker instead of strings
-	- generated interface for ::xotcl::methodproperty

-2009-07-04  Gustaf A. Neumann  
-
-
-	- ::xotcl::my generated
-
-
-	- generated interface for ::xotcl::relation
-
-
-	 - support for generating interface for ::xotcl commands
-	- generated interface for ::xotcl::alias
-
-
-	- removed compatibility for versions before Tcl 8.4 (was not tested
-	  anyhow) This version requires at least Tcl 8.4.
-
-2009-07-01  Gustaf A. Neumann  
-
-
-	- separated C-code generator from declarations
-
-2009-07-01  Gustaf Neumann  
-
-
-	 - moved all definitions of method commands to generated code
-	- from 15356 generic/xotcl.c => 13408
-
-2009-06-30  Gustaf Neumann  
-
-
-	- all object methods generated

-
-2009-06-29  Gustaf A. Neumann  
-
-
-	 - !!! removed obsolete features
-	  * ability to specify nonpos args and pos args as different
-	  arguments
-	  * compile flags AUTOVARS, REFCOUNTED, REFCOUNT_TRACE
-	- added -flags with one argument + type
-	- generated all class methods from interface descriptions
-	- transtional version, not all test of regression test work correctly
-
-
-	- 3 class methods generated, handling args/allargs
-
-2009-06-28  Gustaf A. Neumann  
-
-
-	- added check methods
-
-
-	- all " info" commands generated

-
-
-	- objv-stubs for all 23 class info methods
-
-2009-06-28  Gustaf Neumann  
-
-
-	- defined 5 more info methods view generator
-	- simplified objpattern handling
-
-2009-06-28  Gustaf A. Neumann  
-
-
-	- improved changelog entry

-	  definitions in Tcl)
-
-2009-06-27  Gustaf A. Neumann  
-
-
-	- added generator for tclAPI.h
-	- defined 8 info methods based on the new objv parseing

-	- new file: tclAPI.h
-
-2009-06-26  Gustaf A. Neumann  
-
-
-	- implemented yet another objv parser
-	- used currently only for XOTclClassInfoInstancesMethod()
-
-2009-06-25  Gustaf A. Neumann  
-
-
-	- new command: ::xotcl::createobjectsystem  
-	This command creates a basic object system with the specified
-	 as most general root class and the specified metaclass as
-	most general meta class.
-	 Example: ::xotcl::createobjectsystem ::oo::object ::oo::class
-	 In general, it would be possible to remove an objects system
-	 at runtime, but there is so far no tcl interface for this.
-	- extended framework to work with multiple root classes
-	- the basic root class of XOTcl is now ::xotcl::Object again
-	 (instead of ::oo::object) as before. The old setup can be
-	 achieved on the Tcl-layer.
-
-2009-06-25  Gustaf Neumann  
-
-
-	- added metaclass property for root metaclass
-	- metaclass property is set via ::xotcl::relation ... metaclass

-2009-03-02  Gustaf A. Neumann  
-
-
-	some small performance improvements (use CreateHashEntry instead of
-	FindHashEntry, remove unneded argument, improve order of long and
-	expressions)
-
-
-	- some code cleanup
-	- new methods, when compiled with tcl 8.5; + MakeProcError (producing
-	error messages from xotcl methods) + PushProcCallFrame (compile
-	method to byte-code) The new support allows to call code at the begin
-	of a proc without using the old approach based on :xotcl::initProcNS
-
-2009-02-19  Gustaf A. Neumann

-	  and "info exists" is tested against non-existing vars
-
-2009-01-19  Gustaf A. Neumann  
-
-
-	- Correct deletion of user-metaclasses
-	- commenting existing and potential usage of namespace resolvers
-
-2008-12-01  Gustaf A. Neumann  
-
-
-	- Correct deletion of user-metaclasses: Deletion of
-	  user-metaclasses could lead to undestroyable objects, since the
-	  instances of the user-metaclasses were reclassed to
-	  ::xotcl::Object instead of ::xotcl::Class.
-	- extend regression test for such situations

-
-2008-06-23  Gustaf A. Neumann  
-
-
-	   * additional argument for "info precedence": "-intrinsic"
-	  Syntax:  info precedence ?-intrinsic? ?pattern? If

-
-
-	  * check in guards for boolean values, not for integer values, such
-	  that a guard {true} means success
-
-2008-05-30  Gustaf A. Neumann  
-
-
-	   * updating language reference
-	   * Fix contents for %proc in forwarders in cases,
-	 where the forwarder was called via next and
-	 the argument list for next was provided.
-	 Previously, "next" was used for %proc.
-
-2008-05-28  Gustaf Neumann  
-
-
-	   * make "info (inst)?forward -definition name" more robust
-	  (provide an error message, if  is nog given
-	  * New info subcommands "info parametercmd" and "info
-	  instparametercmd"
-	  * export *parametercmds in Serializer, use "-noinit" on slots as well

-
-
-	- new info option for "info instmixin" supporting -guards and
-	  -closure support
-	- extended test cases for "info instmixin"
-
-2008-02-06  Gustaf A. Neumann  
-
-
-	   * Continued with info orthogonality change
-	  info mixin ?pattern?
-	  info instmixin ?pattern?
-	 ?pattern? behaves exactly like in the change of two days
-	 ago. Preceding colons in the name of the queried class are not
-	 required.
-	 Still to do "-closure" in
-	  info instmixin -closure ?pattern?
-	   * In all mentioned calls, where pattern refers to an object/class
-	 and it contains wild-cards, a preceding :: is added automatically
-	 to the search pattern, if it is missing. Since all object names
-	 start with ::, an omitted leading :: in a search pattern is an
-	 obvious mistake
-	   * Made the behavior "pattern" in the following calls identical
-	 concerning wild cards and object lookups
-	  mixin delete pattern
-	  instmixin delete pattern
-	  superclass delete pattern
-	   * extended regresson test
-
-2008-02-05  Gustaf A. Neumann  
-
-
-	 - fix getAllClassMixinsOf to handle combinations of transitive
-	  per class mixins and inheriting per-class mixin via the class
-	  hierarchy, removed getAllSubClasses

-
-	  * Potential incompatibility: provide a uniform interface to the
-	  following info subcommands
-	  info superclass ?-closure? ?pattern?
-	  info subclass ?-closure? ?pattern?
-	  info instances ?-closure? ?pattern?
-	  info instmixinof ?-closure? ?pattern?
-	  info mixinof ?pattern?
-	 In cases, where the option "-closure" is defined,
-	 the values are computed transitively.
-	 In cases, where a pattern is specified, and
-	 the pattern contains meta-characters, a list
-	 of results is returned matching the pattern
-	 (like "string match"). When no matching value
-	 is found, an empty list is returned.
-	 In cases, where a pattern is specified, and
-	 the pattern contains no meta-characters,
-	 a single value is returned korrespinding to
-	 the specified value. The pattern is used
-	 to lookup an object or class, such it is
-	 not necessary to provide fully qualified names).
-	 if there is no match, empty is returned.
-	 Previously, "info superclass" and "info subclass"
-	 returned a boolean value and performed
-	 always a transitive search. Returning ""
-	 is more consistent and more in line with Tcl.
-	 By using the option "-closure" one can
-	 perform the lookup in the transitive
-	 or in the intransitive sets.
-	 Still to do:
-	 children
-	 parent
-	 classchildren
-	 classparent

+2000-06-05 XOTcl 0.81 Release -- Major Changes to Version 0.80
+        - changelog started by Uwe Zdun
+        * xotcl.c:
+        - deep copy/move with all language features
+         - renamed "parameters" to "parameter"
+        - renamed "info filters" and "info mixins" to "info filter"/
+          "info mixin"
+        - added deprecated error message
+        - added "xotcl_interp" command to start an XOTcl slave interp
+        - better "package" support and integration
+        - linearizing of per-object mixin hierarchy with ordinary
+          class hierarchy
+        - isobject, isclass, and ismetaclass with identical interface:
+          all have the obj/cls in question as argument
+        - reference tracing with "info reference", "info referencedby" added
+        - internal xotcl-lib now in predefined.xotcl -> make file
+          automatically creates predefined.h
+        * toplevel-configure added
+        * Actiweb:
+        - early alpha preview for code mobility, registry, web objects
+          added. be careful: the APIs will most likely change in the
+          future
+        - SSL Place
+        * HTTPserver/access:
+        - Open SSL support
+        * xoXML/xoRDF:
+        - RDF Typed Node support
+        - Parsing of several top nodes at once -> mixing of XML and RDF easier
+        - Tests integrated and several new tests
+        - XML/RDF recreation added
+        * xoStore:
+        - Support for tclgdbm added -- thanks to Stefan Vogel for
+          providing the Win version of gdbm
