2007-10-29: <Gustaf.Neumann@wu-wien.ac.at>
* return mixins before procs in procsearch
* added regression test
* Don't though error when the last argument of
"obj info class <...>" or "cl info superclass <....>"
is a non-existing class, but return false instead.
This leaves room for pattern matching.
2007-10-28: <Gustaf.Neumann@wu-wien.ac.at>
* some code refactoring
* making new code more robust
2007-10-23: <martin.matuska@wu-wien.ac.at>
* First version of new info methods "mixinof" and "instmixinof"
- new class info options: "mixinof" and "instmixinof"
- on class destroy entry is now removed from mixin
and instmixin lists
2007-10-12: <Gustaf.Neumann@wu-wien.ac.at>
* Release of XOTcl 1.5.6
2007-10-09: <Gustaf.Neumann@wu-wien.ac.at>
* More fixes for treating gobal volatile objects
during shutdown:
- do not allow to create new objects during shutdown
- do not allow objects to be set volatile during shutdown
- handle cases, where application level destroy methods
fail (this could lead to remaining tcl traces pointing
to destroyed objects)
- handle namespaced variables helding deletion traces
for volatile objects
Guess, it would be much simpler to use Tcl-level
unset traces than C-level unset traces...
2007-10-04: <Gustaf.Neumann@wu-wien.ac.at>
* Revise fix below. The problem was apparently that change of a
call of Tcl_FindCommand to Tcl_GetCommandFromObj(), where the
latter one had bad side-effects when it is called during
deletion. Although the fix below fixed the symptoms, the new
approach is better since it is apparently not required any more
to fetch the cmd during PrimitiveODestroy to ensure it is not
called twice. The problem appeared in XOTcl between 1.5.3 and
1.5.4 and happens only in 8.4.* Tcl.
* Improve debugging code to make it easier to trace
problems with Tcl_Objs.
* Serializer: Added dependency rule in serializer to ensure slots of
superclasses are listed before subclasses. (Thanks to Stefan
Sobernig for reporting the problem)
* Serializer: moved deactivation of traces into "Serializer all"
to get simpler results on "o serialize".
* Regression tests: extended tests to address
the newly identified and fixed problem cases.
2007-09-29: <Gustaf.Neumann@wu-wien.ac.at>
* Fix for Tcl 8.4.16 (and maybe some other recent tcl 8.4.*
versions, 8.5 is fine) for situations, where Tcl variable
contain references to deleted XOTcl objects. The fix added a
epoch increment to CallStackDoDestroy().
2007-09-29: <Gustaf.Neumann@wu-wien.ac.at>
* Fix for cases, where volatile objects are
deleted before the corrsoponding trace variable.
2007-09-18: <Gustaf.Neumann@wu-wien.ac.at>
* Release of XOTcl 1.5.5
2007-09-18: <Gustaf.Neumann@wu-wien.ac.at>
* Fix rpm build (most probably due to TEA 3.6)
2007-09-13: <Gustaf.Neumann@wu-wien.ac.at>
* Use AssocData instead of the clientdata of the
global namespace to store the XOTcl interpreter's
2007-09-13: <Gustaf.Neumann@wu-wien.ac.at>
* Upgrade to TEA 3.6
2007-09-10: <Gustaf.Neumann@wu-wien.ac.at>
* Make forward option -earlybinding more robust, when
forwards are done to Tcl procs
2007-08-16: <Gustaf.Neumann@wu-wien.ac.at>
* Fix introspection problem for copied objects and classes
(remove superfluous ::xotcl::initProcNS)
Must have been a bug from before XOTcl 1.0
* Allow to load XOTcl compiled for Tcl 8.4 to be loaded
into a tclsh8.5 (again, substantial change).
The behavior can be turned off by setting
FORWARD_COMPATIBLE to 0
One can now test now 4 versions:
a) a native version for Tcl 8.4 (without compatibility layer)
b) a native version for Tcl 8.5
c) a version compiled for Tcl 8.4 with compatibility layer in tclsh8.4
d) a version compiled for Tcl 8.4 with compatibility layer in tclsh8.5
Tests showed that the overhead is for the compatibility
layer is between 1.1% and 2.3%, the difference between
tcl8.5 and tcl8.4 is much larger.
2007-08-10: <Gustaf.Neumann@wu-wien.ac.at>
* Release of XOTcl 1.5.4
2007-08-10: <Gustaf.Neumann@wu-wien.ac.at>
* fixed regression test in rdf-tests (introduced
due to autoname changes in 1.4.0)
2007-08-10: <Gustaf.Neumann@wu-wien.ac.at>
* Fixing bugs introduced by VarReform
* Extending regression test to handle the cases
2007-08-07: <Gustaf.Neumann@wu-wien.ac.at>
* More work on Tcl 8.5 and VarReform
Compiles now with stock Tcl 8.5 from CVS
* Make more use faster Tcl_Obj based interfaces
(Many thanks to Miguel Sofer for the suggestions and patch)
2007-08-06: <Gustaf.Neumann@wu-wien.ac.at>
* Changed all references to /tmp to [::xotcl::tmpdir] to honor
TMPDIR TEMP TMP if set
* Handling of variable traces in serializer:
traces might require a different topological sort,
which is hard to handle. Similar as with filters,
we deactivate the variable traces during initialization.
This happens by
(1) replacing the XOTcl's trace method by a no-op
(2) collecting variable traces through collect-var-traces
(3) re-activating the traces after variable initialization
(Many thanks to Stefan Sobernig for the help!)
2007-08-05: <Gustaf.Neumann@wu-wien.ac.at>
* Changes to compile xotcl with the new Var structures in the
head version of Tcl 8.5. This is a rather large change,
the patch is more than 800 lines.
(Many thanks to Miguel Sofer for the help!)
From the Tcl Changelog
*** POTENTIAL INCOMPATIBILITY *** (tclInt.h and tclCompile.h)
Extensions that access internals defined in tclInt.h and/or
tclCompile.h may lose both binary and source compatibility. The
relevant changes are:
1. 'struct Var' is completely changed, all acceses to its
internals (either direct or via the TclSetVar* and TclIsVar*
macros) will malfunction. Var flag values and semantics
changed too.
2. 'struct Bytecode' has an additional field that has to be
initialised to NULL
3. 'struct Namespace' is larger, as the varTable is now one
pointer larger than a Tcl_HashTable. Direct access to its
fields will malfunction.
4. 'struct CallFrame' grew one more field (the second such
growth with respect to Tcl8.4).
5. api change for the functions TclFindCompiledLocal,
TclDeleteVars and many internal functions in tclVar.c
2007-07-27: <Gustaf.Neumann@wu-wien.ac.at>
* fixed a compile problem with a superfluous semicolon in a macro
(Many thanks for Andreas Kupries for reporting and sending a patch)
* fixed two compiler warnings in gcc 4.1.2
2007-07-23 <Gustaf.Neumann@wu-wien.ac.at>
* Pre-Release of XOTcl 1.5.4
2007-07-23: <Gustaf.Neumann@wu-wien.ac.at>
* fixed a bug with empty argument names
(Many thanks for Stefan Sobernig for reporting the bug)
2007-07-03: <Gustaf.Neumann@wu-wien.ac.at>
* allow to call methods from the class to be called
from slot objects (Many thanks for
Nico L'INSALATA for noting this problem).
2007-06-05: <Gustaf.Neumann@wu-wien.ac.at>
* Fixed spelling mistakes in the tutorial
(Many thanks to Robert Hicks for reporting)
2007-05-27: <Gustaf.Neumann@wu-wien.ac.at>
* Fixed potential error with default values for parameters
starting with a "-". (Many thanks to Shishir Ramam
for reporting)
2007-03-16: <Gustaf.Neumann@wu-wien.ac.at>
* fixed a bug where a Tcl call adds a namespace to an object,
but xotcl did not notice it. (Many thanks for Stefan Sobernig
for reporting the bug)
2007-01-14: <Gustaf.Neumann@wu-wien.ac.at>
* fixing error message propagation for methods called via
configure. (Many thanks for Kristoffer Lawson
for reporting the bug)
2006-12-12 <Gustaf.Neumann@wu-wien.ac.at>
* changing "test == " to "test =" as required by FreeBSD
(many thanks to Martin Matuska for providing
the patch)
2006-12-07 <Gustaf.Neumann@wu-wien.ac.at>
* MinGW patches
(many thanks to Martin Matuska for providing
the patch)
2006-11-25 <Gustaf.Neumann@wu-wien.ac.at>
* Release of XOTcl 1.5.3
2006-11-24 <Gustaf.Neumann@wu-wien.ac.at>
* provided compatibility with Tcl 8.5
(checking callframe level instead of empty varframe for toplevel
frames)
* provided compatibility with Tcl 8.4.14
proc->cmdPtr was used in prior releases only to determine the
namespace in which the proc is executed (documented in
tclInt.h). Starting with Tcl 8.4.14, this cmdPtr is used as
well for updating the client data of a cmd, in case the proc is
recompiled. Since XOTcl used the cmdPtr to control the
namespace, this code had to be rewritten differently. The new
version is faster, but uses for filters or mixins slightly more
storage.
* reduced calling overhead of methods with nonpositional arguments
by about 10 percent by avoiding shimmering.
* fixed handling of "return -code break" from xotcl methods
(thanks to Artur Trzewik for the bug report)
* library/comm/Access.xotcl: fixed handling of chunked encoding
2006-09-29 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* Release of XOTcl 1.5.2
2006-09-28 <Gustaf.Neumann@wu-wien.ac.at>
* Extended regression test for nested contains
* fix potential bug in copy-command with c-level client data
(don't copy commands with client data for the time being, rely on
introspection)
2006-09-27 <Gustaf.Neumann@wu-wien.ac.at>
* Fixed memory corruption (accessing feed memory) in the
invalidation of transitive mixins (many thanks to Don Porter for
reporting it and providing suggestions, how to trigger the bug
via Tcl memory debug)
* Removed c++ style comments (many thanks to Andreas Kupries for
reporting)
* package xotcl::trace: allow to trace objects with "Trace add
trace <obj>" not only classes as before (many thanks to jima for
suggesting this)
* fix for nested -contains with new (many thanks to Stefan
Sobernig for pointing this out)
* Added a target test-nohttp for automated regression tests
on machines with firewalls (used for FreeBSD build system)
2006-09-26 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: improved portability for 64bit AMD on FreeBSD (and
maybe on other 64bit platforms as well) all vararg lists are now
terminated by ..., (char *) NULL Previously, some were
terminated by an integer typed zero-value, which can lead to
problems when sizeof(int) != sizeof(char *)
* The vararg interface is used by the following API calls in the
XOTcl code: Tcl_AppendResult(), Tcl_AppendStringsToObj(),
Tcl_VarEval(), XOTclVarErrMsg(). all occurrences are fixed.
* All occurrences of Tcl_AppendResult() removed form xotcl.c
2006-09-24 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: make sure, that no
Tcl_SetIntObj(Tcl_GetObjResult(interp), 1);
happens on shared objects.
2006-09-22 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* Release of XOTcl 1.5.1
2006-09-22 <Gustaf.Neumann@wu-wien.ac.at>
* XOTclNextCmd() exported to external (stub) interface, to allow
applications to call next without going through a Tcl_Eval()
(Many thanks to Scott Gargash for the constructive discussions)
* removed XOTclGetSelfObj() again from the external interface
since the object/class is passed anyhow.
* some minor cleanups and additions to tutorial.
* added small fix mentioned in c.l.t for a more backwards
compatible old parameter interface.
2006-09-21 <Gustaf.Neumann@wu-wien.ac.at>
* Changed interface of XOTclCallMethodWithArgs to contain the
specified number of elements in objv[] rather than the absolute
number. Changed name from XOTclCallMethodWithArg to
XOTclCallMethodWithArgs
* Added XOTclCallMethodWithArgs() to he external interface to
allow C applications faster invocation of XOTcl methods
* Simplified and standardized calling conventions for
C-implemented methods. ClientData receives always the
XOTcl_Object, no matter, what client data was specified during
registration (e.g. XOTCL_NONLEAF_METHOD). Users
can rely on using ClientData for Objects
* Some performance improvements in invocation of XOTcl methods
2006-09-20 <Gustaf.Neumann@wu-wien.ac.at>
* added XOTclGetSelfObj() to he external interface to obtain the
current object from a C application from the callstack
* fixed genstubs target in Makefile.in regenerated all stub files
* removed a few more compiler warnings for the power64 bit
architecture
2006-09-19 <Gustaf.Neumann@wu-wien.ac.at>
* added XOTCL_NONLEAF_METHOD: This constant
must be used fwhen registering C-implemented methods
that call "::xotcl::next" to push the XOTcl activation record.
Example:
XOTclAddIMethod( interp, MyClass, "mymethod", MyMethod,
XOTCL_NONLEAF_METHOD, 0 );
2006-09-18 <Gustaf.Neumann@wu-wien.ac.at>
* fixed a bug in parsing nonpositional arguments, when
e.g. square brackets are used in type declarations for
parameters.
Class C
C instproc foo {{-q:mult[2],optional 1} -x:boolean,optional args} {puts hu}
Tcl lists add another layer of braces
... foo {{{-q:mult[2],optional} 1} -x:boolean,optional args} ....
which have to be removed at the definition time of the parameters.
* fixed a 64-bit problem for POWER5+ machines
* fixed serializer to handle deeper stratification layers
* fixed an autoname crash under NT
(Many thanks to Mark Jannsen for the patch)
2006-09-17 <Gustaf.Neumann@wu-wien.ac.at>
* fixed a bug in deprecated part, when -setter is used in parameter
options.
2006-09-15 <Gustaf.Neumann@wu-wien.ac.at>
* Changed "test -e" to "test -f" in Makefile.in, since
the standard test command in Solaris does not understand "test -e"
(Many thanks to Andreas Kupries for reporting)
2006-09-14 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* Release of XOTcl 1.5.0
2006-09-13 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* Update of build files for windows
2006-09-10 <Gustaf.Neumann@wu-wien.ac.at>
* added method "contains" to create objects aggregated into
other objects (essentially a value added back-port of the OpenACS
version).
* based method "slots" on method "contains" for improved orthogonality
* rearranging sections in the tutorial
* deleted obsolete sections from the tutorial
* serializer: when an object is defined as exported, export the whole
object tree (no need to specify export of all slots for exported objects)
2006-09-08 <Gustaf.Neumann@wu-wien.ac.at>
* added -verbose to forward options
* added subst to the tcl-impored methods
* fixed a bug with .... -slots {Attribute new -name a1}
(Many thanks to neophytos for reporting}
* provide method serialize (for Object), when the serializer package is loaded
2006-09-07 <Gustaf.Neumann@wu-wien.ac.at>
* provided Tcl 8.5a4 compatibility
* spellechecking langref, make terminology more consistent
(naming of arguments like .e.g methodName)
2006-09-04 <Gustaf.Neumann@wu-wien.ac.at>
* update of tcl.m4 for newest TEA from CVS
2006-09-03 <Gustaf.Neumann@wu-wien.ac.at>
* "mixin|filter|instmixin|instfilter set ..." deprecated, use
"mixin|filter|instmixin|instfilter assign ..." instead
2006-09-01 <Gustaf.Neumann@wu-wien.ac.at>
* fixed a bug in the xotcl trace module (many thanks to jima for reporting)
* extended procsearch to report parametercmd and instparametercmd
2006-08-30 <Gustaf.Neumann@wu-wien.ac.at>
* extended procsearch to report as well [inst]parametercmd
2006-08-26 <Gustaf.Neumann@wu-wien.ac.at>
* extended procsearch to report as well [inst]forward and [inst]cmd
2006-08-25 <Gustaf.Neumann@wu-wien.ac.at>
* new subcommand "info slots"
* implemented backwards bug-compatible "info parameter", deprecated
2006-08-23 <Gustaf.Neumann@wu-wien.ac.at>
* added system slots and attribute slots (see documentation)
2006-08-21 <Gustaf.Neumann@wu-wien.ac.at>
* changed the implementation of the configure command
and setrelation command to use Tcl_GetIndexFromObj();
* added the subcommand "class" and "superclass" to the
the setrelation command.
2006-08-22 <Gustaf.Neumann@wu-wien.ac.at>
* fixed a bug with nonpositional arguments, some
positional arguments and "args"
* fixed a bug in nonpositional arguments when called without
arguments
* improved error messages in connection with nonpositional arguments
* extended interface of XOTclErrBadVal() to provide better error messages
(this changes the stub interface, so we have to change the version number)
2006-08-21 <Gustaf.Neumann@wu-wien.ac.at>
* new command for registering predefined C-implemented Tcl commands
as methods
::xotcl::alias <class>|<obj> <methodname> \
?-objscope? ?-per-object? <cmdname>
"-objscope" has the same meaning as for forwarder,
"-per-object" has the same meaning as for the method "method",
This command is somewhat similar to "[inst]forward -earlybinding",
but can be used to bootstrap xotcl (when e.g. no methods are
available).
2006-07-20 <Gustaf.Neumann@wu-wien.ac.at>
* Documentation bug: method volatile was documented
as a method of class, but is documented as a method of object
(Many thanks to Kristoffer for reporting)
2006-05-22 <Gustaf.Neumann@wu-wien.ac.at>
* package.xotcl: evaluating calls to "tcl_package" in the
global namespace instead of the current. This fixes problem of
xotcl 1.4.* with xotclide. Many thanks to
Bill Paulsen and Artur Trzewik for identifying the problem and
suggesting a fix.
2006-04-20 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: new option for the argument substitution. When the argument
list of the forward command contains "%argclindex {a b c}", then
depending of the number of arguments at invocation "a", "b"
or "c" is substituted.
* New option for forwarder: The option -earlybinding can be used to look
up the function pointer of the called Tcl command at
definition time of the forwarder instead of invocation time.
This option should only be used for calling C-implemented Tcl commands)
2006-03-22 <Gustaf.Neumann@wu-wien.ac.at>
* deprecated command filterappend, instfilterappend, mixinappend,
instmixinappend, tclcmd, insttclcmd deleted
2006-03-20 <Gustaf.Neumann@wu-wien.ac.at>
* allow single colons in method names (fix in xotcl.c, NSTail())
2006-02-17 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* release of 1.4.0
2006-02-17 <Gustaf.Neumann@wu-wien.ac.at>

* fixed dependencies created for rpm binaries
* mak compile cleaner for gcc 4.* under linux
2006-02-08 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* fixed a bug with transitive mixins
2006-02-02 <Gustaf.Neumann@wu-wien.ac.at>
* Upgrade to TEA 3.5
2006-01-10 <Gustaf.Neumann@wu-wien.ac.at>
* fixing exit behavior with variable traces in multi-threaded
environments (volatile objects could be demalloced twice before)
2006-01-08 <Gustaf.Neumann@wu-wien.ac.at>
* allowing tcl commands and variables as default values for parameters; previously,
only one-word commands were allowed.
2006-01-07 <Gustaf.Neumann@wu-wien.ac.at>
* ::xotcl::configure options can be called with one (for query)
and two (for setting) arguments (similar to set)
* new option: ::xotcl::configure softrecreate on|off
if softrecreate is set, class relations (superclass, subclass, class, instances)
are not affected by a recreate; this allows files with class definitions
more easily to reload
* don't destroy namespace imported child objects
2006-01-06 <Gustaf.Neumann@wu-wien.ac.at>
* unsetting the global variable "cmd" from predefined.xotcl
(Many thanks to Koen Danckaert for reporting)
2006-01-05 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* fixing incorrect state in filters after next
* extended regression test
2006-01-02 <Gustaf.Neumann@wu-wien.ac.at>
* info children returns true children, no namespace imported objects/classes
* extended regression test
2005-12-20 <Gustaf.Neumann@wu-wien.ac.at>
* upgrading configure scripts of subcomponents to TEA 3.4
2005-12-17 <Gustaf.Neumann@wu-wien.ac.at>
* fixing missing omitted message for unknown subcommand to self
2005-12-07 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* release of 1.3.9
2005-12-06 <Gustaf.Neumann@wu-wien.ac.at>
* fixed bug with error propagation when gett/setter methods are
used for parameters (many thanks to Manfred Stelzhammer for
pointing this out)
2005-12-04 <Gustaf.Neumann@wu-wien.ac.at>
* Upgraded TEA to 3.4
* updated rpm build (many thanks to Ildiko Schmidt and Alexander Bergolth)
2005-11-28 <Gustaf.Neumann@wu-wien.ac.at>
* new command ::xotcl::__qualify: convert an relative name
into an command name (exactly as create does it, ignoring
namespaces from transparent interceptors)
2005-11-26 <Gustaf.Neumann@wu-wien.ac.at>
* require automatically a namespace when a childobject is added
2005-11-18 <Gustaf.Neumann@wu-wien.ac.at>
* new switch -nocomplain for "mixin|instmixin|filter|instfilter delete"
to avoid error messages when deleting entries not there (similar unset)
2005-11-10 <Gustaf.Neumann@wu-wien.ac.at>
* "<obj> info vars" does not trigger read traces anymore
* fixing version numbers for package require
(many thanks to Andreas Kupries for the report)
* Serializer: exportMethods accepts forwards/instforwards now
as well
2005-11-02 <Gustaf.Neumann@wu-wien.ac.at>
* new subcommand of self: [self args] return the full argument list
of the current call
2005-10-02 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* release of 1.3.8
2005-10-01 <Gustaf.Neumann@wu-wien.ac.at>
* fixed a bug concering __unknown called via mixin method
(many thanks to Zoran for the report)
* fixed a memory leak in isMetaClass() in connection with
instmixins (many thanks to Ben Thomasson for the report)
2005-09-28 <Gustaf.Neumann@wu-wien.ac.at>
* fixed bug in instvar (many thanks to Koen Danckaert for the report)
extended regression test
2005-09-27 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* release of distribution XOTcl 1.3.7
2005-09-26 <Gustaf.Neumann@wu-wien.ac.at>
* new check option "switch" for non positional arguments.
If .... -somearg:switch is specified in the definition
of a method, this behaves like "boolean", except that
no additional argument is specified during invocation.
A default value of "off" can be turned on, as well as the
default value "on" can be turned off by specifying the switch
in an invocation.
2005-09-25 <Gustaf.Neumann@wu-wien.ac.at>
* defined an experimental method named "method"
* new global command "::xotcl::configure filter on|off"
to deactivate all filters for an interpreter. This is
needed for serializing code with active filters.
* Changed xotcl serializer to use "::xotcl::configure"
2005-09-14 <Gustaf.Neumann@wu-wien.ac.at>
* Fixing serializer to enforce methods on ::xotcl::Object or ::xotcl::Class
before other objects and classes
2005-09-13 <Gustaf.Neumann@wu-wien.ac.at>
* adding two package require into library files
(many thanks to Andreas Kupries for the report)
2005-09-09 <Gustaf.Neumann@wu-wien.ac.at>
* fixing various namespace issues in library files to make
regression test working again.
2005-09-08 <Gustaf.Neumann@wu-wien.ac.at>
* documentation and regressiontest for "self isnextcall" added
* added further regression tests, documentation improvements
* Httpd: changed classes
AccessControl BasicAccessControl
DigestAccessControl Responder
to Httpd::AccessControl ... Httpd::Responder
in order to reduce namespace pollution; applications
refering to these must use now these names
2005-09-07 <Gustaf.Neumann@wu-wien.ac.at>
* fixed callstack information for expr; old code could
believe (in connection with forward) to be in an uplevel when
a forward to expr was called. This could result in a wrong
result for [self]....
* merged first bunch of files from Andreas Kupries to
make libraries more namespace clean. fixed a few namespace iusses
in the libraries. Many thanks to Andreas Kupries!
* fixed refrence resolving in istype; the following works now the same
way:
C create c1
c1 istype ::C
c1 istype C
2005-09-02 <Gustaf.Neumann@wu-wien.ac.at>
* code cleanup: removed ifdefs for TCLCMD
2005-08-04 <Gustaf.Neumann@wu-wien.ac.at>
* fixed instvar implementation when variable names
are empty strings (many thanks to Zoran for reporting this)
2005-07-13 Uwe.Zdun@wu-wien.ac.at>
* new subcommand for self: [self isnextcall]
is true, if the current method was called via next.
This fixes the abstact method.
2005-05-04 <Gustaf.Neumann@wu-wien.ac.at>
* prevent new from overwriting an existing object
(increment further until unused name is found)
2005-07-04 Jeff Hobbs <jeffh@activestate.com>
* providing update for configure
2005-04-04 <Gustaf.Neumann@wu-wien.ac.at>
* allow xotcl to be used in safe safe interpreters
~rlwrap /usr/bin/tclsh
% package req XOTcl
1.3.7
% interp create -safe slave
slave
% load "" xotcl slave
% slave eval ::xotcl::Object o1
::o1
2005-03-24 <Gustaf.Neumann@wu-wien.ac.at>
* implemented resolving for references to classnames not
in the current namespace such that the following works
namespace eval foo {
Class M -superclass Class
}
without the need of specifying "-superclass ::Class"
* implemented resolving for references to imported class names
such that the following works
namespace eval foo {
namespace import ::bar::A
Class M -superclass A
}
2005-03-17 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* release of distribution XOTcl 1.3.6
2005-03-16 <Gustaf.Neumann@wu-wien.ac.at>
* extended semantics of meta class definitions:
old:
a meta class is either ::xotcl::Class or one of its
direct subclasses
new:
a meta class is either ::xotcl::Class or a class
inheriting from ::xotcl::Class
The subtle difference is that with the new definition
every class can be made to a superclass by adding an instmixin
of Class (or one of its subtypes) to it. Before this change
it was necessary to alter the Class hierary explicitely.
In order to define that every class should be a metaclass,
one can use now
Object instmixin Class
instead of the rather complicated solution i posted on the
xotcl mailing list not long ago.
* new info subcommand: <object> info precedence
* fixed possible crashes of objects are called with class methods
(e.g. due to instmixins)
* fixed bug when instmixins are defined recursively
(e.g. Class instmixin Class)
* code refactoring, fixed erroneous documentation of c code

such that htmldoc 1.8.24 works with it
* extended regression test, reduced dependency on tests
2005-03-11 <Gustaf.Neumann@wu-wien.ac.at>
* fixed bug noted by Kristoffer Lawson:
- Don't allow an object to be changed to a class via "o class Class"
- Don't allow an object to be recreated (without alloc) to a Class
* fixing the following command
namespace eval foo {
Class m
Object o -mixin m
}
such that m is resolved from the foo namespace.
The ::xotcl:: namespace is now skipped, since a
helper method that calles the primitive setting command
is defined there
2005-03-01 <Gustaf.Neumann@wu-wien.ac.at>
* improved documentation of next in langRef
2005-02-23 <Gustaf.Neumann@wu-wien.ac.at>

2005-01-07 <Gustaf.Neumann@wu-wien.ac.at>
* code cleanup for nonpos args
* new methods for Serialzer:
- Serializer methodSerialize (to serialize methods)
- Serializer exportMethods (to export methods from the
xotcl namespace via ::Serializer all
- Serializer exportObjects (to export Objects from ::xotcl::*)
* put Serializer into a namespace (::Serializer is auto-exported)
* fix for serializer, when xotcl is not imported globally
* aolserver: support for namespaced objects in xotcl.tcl
2005-01-06 <Gustaf.Neumann@wu-wien.ac.at>
* made introspection options for methods with nonpos args
compatible with Tcl
* adding functionality to allow nonpos args and positional args
to be specified in the same argument list (still supporting
the syntax with separate lists)
2005-01-05 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* Added support for defaults + non-pos args in info args,
default, instargs, instdefault
* fixed bug: Check Boolean in non-pos args crashed with 2 args
2004-12-15 <Gustaf.Neumann@wu-wien.ac.at>
* fixed crash for empty arguments
(thanks to Gerald Stermsek for reporting this bug)

* Fixed bin-tar target to include sdbm+gdbm+expat
* Improved documentation (tutorial and langref) for forwarding options
* using $prefix in install-aol, provided a README.aol file
* more general fix for namespace handling; still possible problem
with shared Tcl_Objs of type XOTclObject, when referred to from
different namespaces.
2004-09-15 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* fixed bug: non-pos args did not work correctly with default
values. Thanks to Bryan Schofield for reporting this bug.
Added tests for non-pos args + default values.
2004-09-09 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* fixed possible accesses to object namespaces that got already
destroyed by TCL, by checking for ((Namespace
*)nsPtr)->deleteProc is not NULL, ie. it is still set to
XOTcl's Namespace Delete Proc, and not invalidated by
TclTeardownNamespace yet. add test for this to testx. Thanks
to Kristoffer Lawson for reporting this bug.
* fixed mis-formating in tutorial (only visible in browsers
other than Mozilla)
2004-09-02 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* temporary fix for alloc behavior to deal with explicit namespace changes
by user, thanks to michael.heca@email.cz for reporting the
bug. Added a test for this change.
2004-08-26 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* release of distribution XOTcl 1.3.1
2004-08-26 <Gustaf.Neumann@wu-wien.ac.at>
* removed dependencies on TclGetInterpProc(), added define
USE_INTERP_PROC if someone needs this. If nobody complains,
we will remove this in the future
2004-08-22 <Gustaf.Neumann@wu-wien.ac.at>
* fixed nonposargs, when used with checker procs and
spaces in arguments
* auto-generating docs in build tree (instead in
source tree)
* cleanup and documentation of somewhat confusing declations
in xotcl.h and xotclInt.h (XOTcl_Object and
XOTclObject)
* make tar makes distclean first
2004-08-19 <Gustaf.Neumann@wu-wien.ac.at>
* if configure is run outside the src tree the directory
structure is now built on the fly. All binary
output files are now placed in the built-tree.
2004-08-18 <Gustaf.Neumann@wu-wien.ac.at>
* added a regresion test for serialzer
* fixed a "last minute" bug in serializer
* configure changes: made subdirs relative to $srcdir,
set XOTCL_SRC_DIR to $srcdir to make build succeed
from outside dir
2004-08-17 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* release of distribution XOTcl 1.3.0
2004-08-17 <Gustaf.Neumann@wu-wien.ac.at>
* fixing make for rpm
* tweaking configures stuff to work with rpm

* adding two sections to tutorial, updated langref.xotcl
2004-08-15 <Gustaf.Neumann@wu-wien.ac.at>
* Adding non positional arguments to serializer
2004-08-12 <Gustaf.Neumann@wu-wien.ac.at>
* fixed a possible core dump when 'my' was called without
args (many thanks to Bryan Schofield for noting)
* some code generalization and cleanup
2004-08-01 <Gustaf.Neumann@wu-wien.ac.at>
* changes to forward and instforward:
providing positional arguments for the
forwarder. It is now possible to prefix the
arguments with "%@POS ", where POS can be a
positive or negative number or "end". A negative
offset can be used to address relative to the end
2004-08-01 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: calling __unknown when an object with an unknown
parent namespace is called (for handling nested object
classes in Zoran's ttrace package)
2004-08-01 <Gustaf.Neumann@wu-wien.ac.at>
* yet another fixed access to freed memory (when the configure
method returned a non numerical value, which was tried to be
converted into a number; setting refcounts properly helped.
(thanks to Zoran for his help with Purify )
* minor code cleanup
* test with tcl 8.4.7
2004-07-29 <Gustaf.Neumann@wu-wien.ac.at>
* changes to forward and instforward:
+ %some-command executes some-command at invocation time and
substitutes result
+ substitution extended to all arguments (also on callee)
2004-07-28 <Gustaf.Neumann@wu-wien.ac.at>
* yet another fixed access to freed memory
(thanks to Zoran for his help with Purify )
2004-07-26 <Gustaf.Neumann@wu-wien.ac.at>
* fixed bug in filters in connection with instmixin;
inactive tcl callstack frame was dereferenced. This fixed as well
a potential uplevel bug
* fixed access to freed memory (thanks to Zoran for his help with Purify )
2004-07-23 <Gustaf.Neumann@wu-wien.ac.at>
* implemented experimental next method for delegating same-named procs
to different objects
2004-07-20 <Gustaf.Neumann@wu-wien.ac.at>
* fixed a potential crash when a instmixin was registered on itself
2004-07-19 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* added checkoptions to non pos args
* added tests & documentation of non pos args
2004-07-18 jim@jam.sessionsnet.org
* Added file autogen.sh, to generate all configure files
* Added file autoclean.sh, to clean whole source tree, incl. configure
2004-07-18 <Gustaf.Neumann@wu-wien.ac.at>
* added removal of autom4te.cache to distclean
* make doc added to "all" target
* auto-generated html docs are removed in a make clean
* remove all *~ files in directory tree via find (ok with TEA3?)
2004-07-11 jim@jam.sessionsnet.org
* revamped configure recursion
* added "--with-xotcl=<pathToXotclConfig.sh>" to child configure.ins
* arranged for root configure to call child configures specifying path
* located and fixed bug where parts of the build cannot find xotcl.h
if xotcl was not "make install"ed (bug implies build always finds
old includes)
* ensured "make clean" and "make distclean" still worked
* TODO: clean should remove emacs backup files
distclean should remove autom4te.cache
docs should be built during make, installed during make install
and removed from the build dir during make clean.
2004-07-03 <Gustaf.Neumann@wu-wien.ac.at>
* extended commands filter, mixin, instfilter, instmixin:
These commands are changed in a backward compatible manner. They
can be used as follows
obj mixin same as: obj info mixin
obj mixin {C1 C2} same as: obj mixin set {C1 C2}
obj mixin set {C1 C2} sets the mixins for obj
obj mixin get same as: obj info mixin
obj mixin add C3 adds a mixin on front of the mixin list
obj mixin add C3 end adds a mixin at the end the mixin list
obj mixin add C3 3 adds a mixin at the 3rd position
obj mixin delete ::C3 removes the mixin from the mixin list
The same semantics are available as well for filter, instmixin
and instfilter.
The implementation uses the forwarder and is extensible, new
subcommands can be added. As a side effect, the c-code was reduced
by 50 lines.
* the commands mixinappend, filterappend, instmixinappend and
instfilterappend were marked as deprecated and will be removed
in future versions
2004-07-02 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* integrated support for non-positional arguments for procs
and instprocs
2004-07-02 <Gustaf.Neumann@wu-wien.ac.at>
* rename forward option -inscope to -objscope
* xotcl.c: added current namespace prefix, when a forwarder is
defined with -objscope and no namespace prefix was specified
* optimized forward/instforward such it reaches practically
same speed as tclcmd/insttclcmd.
* removed tclcmd/insttclcmd
* added tests for forward to regression test suite
* applied and fixed the config improvements by Jim Lynch <jwl@debian.org>
2004-07-01 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: allow literal %self, %proc, %1 etc. as arguments of the forwarder:
arguments in the definition of a forwarder proc
starting with two %-characters are changed into arguments starting
with one %
* xotcl.c: forced options to be placed in forward definition after
<proc> before <target>
* xotcl.c: new info option for Object and Class:
info <inst>forward ?-definition? ?pattern?
list the defined forwarder for the class/object.
* Serializer.xotcl; Added handling of the forwarders to the serializer.
Therefore forwarders are kept in the serialized state.
2004-06-29 <Gustaf.Neumann@wu-wien.ac.at>
* changed name of delegator methods to forward/instforward
* removed most of the switches of the forwarder. We have now
obj forward <proc> ?options? <target> ?arglist?
where arglist might contain
* %self for inserting the forwarding object
* %proc for inserting the forwarding method
* %1 for using the first argument of the invocation
options might contain:
-inscope: evalute method in obj scope
-methodprefix: prefix, to be added in front of called method
(to avoid name clashes with methods like "set", "mixin" etc.)
-default list-of-methods: to be used in connection with %1, when there
are not enough arguments in the actual call.
2004-06-24 <Gustaf.Neumann@wu-wien.ac.at>
* fixed coredump for delegation to object without method specified
(many thanks for Bryan Schofield for the bug report)
2004-06-20 <Gustaf.Neumann@wu-wien.ac.at>
* removed inclusion of <tclCompile.h>
* second version of delegator methods cmd and instcmd
A delegator method is defined via
Class instcmd method COMMAND ARGS
a call to the defined method with some args
obj method arg1 arg2 arg3...
is mapped to
COMMAND ARGS arg1 <caller> INSERTTOKENS arg2 arg3...
Class instcmd <methodname> <commandname> \
?-nocaller? \
?-nomethod? \
?-inscope? \
?-skip nr_of_tokens? \
?-insert tokens?
?-prefix string? \
?-defaultmethod subcommand? \
where
methodname: name of an instcommand for the class
to be registered,
commandname: command that receives delegation
-nomethod: don't insert the callers method
-nocaller: don't insert caller after method
-inscope: evalute method in obj scope
-skip: skip n arguments from the call. "-skip 1"
means that not the "method" from the invocation is
used as the method call, but the first argument
-prefix: prefix, to be added in front of
called method (to avoid name clashes
with "set", etc.)
-insert: tokens to be inserted after the caller
-defaultmethod: when number of arguments is not sufficient
to determine the called method, use the specified
value to be used as method name (only useful when
-skip is used and the arguments run out)
(e.g. [$obj info] be mapped to COMMAND showInfoOptions)
2004-06-18 <Gustaf.Neumann@wu-wien.ac.at>
* added *.a to CLEANFILES in configure.in to rm stublibfile
on a "make clean"
* added subdir traversal for distclean
2004-06-13 jim@jam.sessionsnet.org
* fixed make distclean target
factored list of configure output files into macro made sure
value of output files got through to make distclean target
2004-06-12
* changed namespace treatment in procs/instprocs
in provious versions, methods were evaluated in the
namespace where they are invoked. This has the problem that
either the xotcl primitives (next,my,self) have to be
prefixed in methods by ::xotcl::, or ::xotcl::* has to be
imported globally. Now, the instprocs are evaluated in the
namespace where they are defined.
* computing default prefixes in insttclcmd/tcllcmd for
not fully qualified commands
2004-05-29 <Gustaf.Neumann@wu-wien.ac.at>
* first version of instdelegatecommand
* defined metaclass ::xotcl:.SelfApplicableClass to allow
for instprocs of this class to be applicable for itself
(useful for delegation objects)
* first version of ::xotcl::relations
(for relations between objects and classes and for
inter-class-relations)
2004-05-22 <Gustaf.Neumann@wu-wien.ac.at>
* fixed path for installing files in Makefile.in
(many thanks to Jeffrey Hobbs)
* fixed path searching in xotcl.m4
2004-05-07 <Gustaf.Neumann@wu-wien.ac.at>
* fixed compile problems under HPUX
(with the help of Attila Dona')
* fixed some compiler warnings in tcl-expat showing up
(some are still missing)
with -Wall -Wconversion -Wno-implicit-int
2004-04-30 <Gustaf.Neumann@wu-wien.ac.at>
* removed duplicates from results from [obj info methods]
* fixed GENERIC_HDRS in configure.in and Makefile.in
* fixed documentation bugs for "info children" and
"info classchildren"
* fixed an incorrect error message, when method called
from a mixin was not found.
2004-04-25 <Gustaf.Neumann@wu-wien.ac.at>
* alloc returns name of created object
* On an "Object create ::o1 -noinit" the noinit option
deactivates the search for default values
(as used in the serializer)
* TEA3 changes:
- re-included xotclConfig.sh file in xotcl dependent
libraries
- fixed variable contents in xotclConfig.sh file
- passing of include and spec file for gdbm
2004-04-10 <Gustaf.Neumann@wu-wien.ac.at>
* start to move to TEA3
* moved tcl scripts xotclsh and xowish into apps/utils
* made minimal build independent from tclsh;
new target libraries-pkgindex, fulldoc, doc removed
from default targets
* at least for the time being, no static shells
2004-03-23 <Gustaf.Neumann@wu-wien.ac.at>
* added a flag --with-aolserver3 to configure and removed
the checking of the current directory to determine whether
or not to compile an AOLserver 3.* module. Thanks to Jim
Lynch to suggestion it.
2004-03-03 <Gustaf.Neumann@wu-wien.ac.at>
* fixed a potential crash in procSearch method (Thanks to
Artur Trzewik for the good error report)
2004-02-29 <Gustaf.Neumann@wu-wien.ac.at>
* callMethod* calls DoDispatch instead of ObjDispatch
* adding a callStackPush() for XOTclOEvalMethod() such that
'o eval self' returns '::o'
2004-02-21 <Gustaf.Neumann@wu-wien.ac.at>
* added link to XOTcl wiki to xotcl homepage.
2004-02-20 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* release of distribution XOTcl 1.2.0
2004-02-17 Uwe Zdun <uwe.zdun@wu-wien.ac.at>

2004-02-16 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* added self class and self proc context to GuardCall
* removed guardedScope and info guardedlevel completely
from the code
-> use parameters instead (see tutorial)
* rewritten the tutorial text for mixin/filter guards completely
* added new files to Win makefile.vc
2004-02-14 <Gustaf.Neumann@wu-wien.ac.at>
* experimental new command "self guardedlevel" as replacement
for getGuardedScope
* added documentation for self callinglevel, self
activelevel and the methods upvar and uplevel
* used a bold font for predefined Tcl and XOTcl words
in the HTML version of the tutorial
2004-02-13 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c more code cleanup:
- some minor performance improvement
- used the same idiom for iterating over a class
hierarchy consistently
- simplified the usage of ComputeOrder() and let
the optimizer do more work
2003-02-04 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* xotcl: removed MixinRemoveFromMixinStack,
MixinRemoveFromCmdPtr, MixinRemoveOnObjFromCmdPtr,
FilterRemoveFromFilterStack,
FilterRemoveFromCmdPtr, FilterRemoveOnObjFromCmdPtr ... and
replaced with simple forward stepping in cmd list.
* made the mem count work with multi, single-threaded interpreters
2003-02-03 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* testx: tests for CmdListReplaceCmd, MixinRemoveFromMixinStack,
MixinRemoveFromCmdPtr, MixinRemoveOnObjFromCmdPtr,
XOTclOGetGuardedScopeMethod, XOTcl_InterpObjCmd,
XOTclOVwaitMethod,
* xotcl: removed XOTclAssertionRename,
simplified XOTcl_RenameObjCmd
* corrected mistakes in tutorial code for filterguards.
2004-01-31 <Gustaf.Neumann@wu-wien.ac.at>
* performed coverage analysis of regression test
* changed unsuccessful branches into asserts
* extended testx.xotcl for better coverage
2004-01-28 <Gustaf.Neumann@wu-wien.ac.at>
* Streamlined code; removed mixinChainOn from mixinStack and
filterChainOn from filterStack and use callstack
frameTypes instead.
* some performance improvements
2004-01-27 <Gustaf.Neumann@wu-wien.ac.at>
* implemented uplevel method
(uses [self callinglevel] when no level specified)
* fixed a bug in next, when methods on the same object are called
from within a mixin class and filters are defined
* some performance improvements
2004-01-19 <Gustaf.Neumann@wu-wien.ac.at>
* added more test cases,
* upvar method fully functional
* simplified CallFrame management on XOTcl stack
(wish, CallFrame had ClientData !!!)
* Reduced size of XOTclCallStackContent
* modularized xotcl more (new file xotclShadow.c; all shadowing
of Tcl commands and access of global tcl obj commands is
treated there)
* included a fix from Zoran for thread exit handlers.
2004-01-16 <Gustaf.Neumann@wu-wien.ac.at>
* defined upvar method (uses [self callinglevel] when no level
specified)
* simplified stringIncrement method and added a couple of
assert().
2004-01-15 <Gustaf.Neumann@wu-wien.ac.at>
* allow volatile to be called from toplevel
* decrementing refcount of global objects as needed
(some had a high increment)
2004-01-14 <Gustaf.Neumann@wu-wien.ac.at>
* method 'new' now uses stringIncrement, which replaces the name
generation based on numbers by a name generation based on
strings. The strings are constructed by small and capital
letters plus digits and correspond to a number of a number
system with the basis of 26+26+10=62. These strings can grow
up to memory size. XOTcl can run as a server practically
infinitely long generating objects with 'new'.
* new package xotcl::upvar-compat
This package provides backward compatibility with earlier
versions of xotcl that redefined upvar/uplevel such that
these commands ignore inactive filter and mixin frames
(upvar behaves the same whether or not a filter is
installed). Newer scripts should use
upvar/uplevel [self callinglevel] var/command
instead. This package can be used via
package require xotcl::upvar-compat
* moved resetting of shadowed tcl commands after the deletion
of object (as suggested by Zoran)
2004-01-11 <Gustaf.Neumann@wu-wien.ac.at>
* all occurrences of uplevel/upvar equipped with
[self callinglevel] such that library works with standard
uplevel/upvar
* faster version of 'new' method (more than 20% faster,
using c-variable, faster long to ascii conversion)
* objinst (of oo-bench) about 17% faster
2004-01-10 <Gustaf.Neumann@wu-wien.ac.at>
* polished macros XOTcl_FrameDecls, XOTcl_PushFrame,
XOTcl_PopFrame (2 versions, slower version with less
dependencies on tclInt.h)
* removed mixinCalls and filterCalls from interpreter state.
* removed unneeded macros
2004-01-08 <Gustaf.Neumann@wu-wien.ac.at>
* fixed bug on exit, when no threads are enabled
(different cleanup strategy in threads)
* fixed crash on deleted Tcl_Cmd, when xotcl debugging output
is turned on
* some more code cleanup
2004-01-07 <Gustaf.Neumann@wu-wien.ac.at>
* removed varFramePtr from xotcl callstack
* removed unneeded variables from runtime state
* resetting of csc->callsNext after a next call
* added "methods" to info info
2004-01-06 <Gustaf.Neumann@wu-wien.ac.at>
* cutting of callframes removed completely
* 2 new subcommands for self:
- self callinglevel: returns the tcl stack level to address
the invocation of the actual method
- self activelevel: returns the topmost active stack entry
from the xotcl stack
Both commands return the absolute level number (syntax #n)
if called from an xotcl method or 1 if called from a tcl
proc. These subcommands are designed to be used in the form
of "upvar [self callinglevel] a b"
* Replaced C implementation of uplevel and upvar
(with callstack manipulation) by a simple Tcl proc that uses
[self callinglevel] as default level (if is was not called
with an explicit level).
* Extended test suite
* Changed all variables of type "Interp *" to "Tcl_Interp *"
and defined macros Tcl_Interp_XXXX to access component XXXX
* Changed all variables of type "CallFrame *" to
"Tcl_CallFrame *" and defined macros Tcl_CallFrame_XXXX to
access component XXXX
2004-01-04 <Gustaf.Neumann@wu-wien.ac.at>
* callstack manipulation reduced significantly
* speedup on xoRDF.test about 7%
* self callingobject/callingclass/.... refers always to
last invocation (ignoring next-chain)
* consequence: mixins and filters are transparent on the
callstack
* possible extension "self previous ?n?" similar to "self next"
to obtain information about next chain
* possible extension "self level ?n?" similar to
"info level ?n?" to obtain information about call stack
2004-01-02 <Gustaf.Neumann@wu-wien.ac.at>
* Changed all variables of type "Namespace *" to
"Tcl_Namespace *" and defined macros Tcl_Namespace_XXXX to
access component XXXX
* generalized invocation on callProcCheck and
handling of calldata in new function DoCallProcCheck
* overall code cleanup
* extended test suite with tclmd and insttclcmd
2004-01-01 <Gustaf.Neumann@wu-wien.ac.at>
* fixed loop on invocation of methods registered by
the tclcmd method
* allowed to register fully qualified commands via
tclcmd or insttclcmd
* made insttclcmd to work from mixin or instmixclasses
* renamed "next" method to "__next"
* restored old behavior of defaultmethod
2003-12-31 <Gustaf.Neumann@wu-wien.ac.at>
* Changed all variables of type "Command *" to "Tcl_Command"
and defined macros Tcl_Command_XXXX to access component XXXX
* new predefined method self: [<object> self] returns fully
qualified name of object
* potential incompatibility:
calling an object without name does not return fully
qualified name, use "self" method (see above) instead.
To keep backward compatibility, define
Object instproc defaultmethod {} {return [my self]}
* New method "<obj> next" can be used to invoke next
on the last recent invocation of a method on <obj>.
<obj> must be on the callstack, otherwise an error message
is generated
* The new defaultmethod calls next on parent object to
prohibit shadowing of methods through sub-objects
2003-12-28 <Gustaf.Neumann@wu-wien.ac.at>
* new functions: CallStackUseActiveFrames()/CallStackRestoreSavedFrames()
to to avoid walking through and modifying the whole stack
when locating an active frame to set variables (using in
-volatile, instvar, info defaults) callstackcutframes still
used in info level, uplevel, upvar, info callingproc,
callingclass, callingobject
2003-12-25 <Gustaf.Neumann@wu-wien.ac.at>
* update of various library functions (such as Httpd) to
use sub-objects as methods (avoids calls of [self]::objname)
2003-12-19 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: allow to call sub-objects as methods via "my"
2003-12-16 <Gustaf.Neumann@wu-wien.ac.at>
* added logdir as parameter for Place (HttpPlace)
* fixed handling of content-length == 0 in Httpd.xotcl
to avoid Problem with microsoft explorer's WebDav queries
2003-11-13 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* release of distribution XOTcl 1.1.1
2003-12-13 <Gustaf.Neumann@wu-wien.ac.at>
* Removed dependency that certain variable references in
tclConfig.sh (such as
TCL_SHARED_LIB_SUFFIX='${VERSION}${DBGX}.so'); There was a
problem on freebsd systems that use hardcoded "84" instead
of version in this definition, which leads to a problem when
the SHARED_LIB_SUFFIX is used with different VERSIONs (such
as in XOTcl). We set now the suffixes as follows
eval "SHARED_LIB_SUFFIX=${VERSION}${TCL_DBGX}${TCL_SHLIB_SUFFIX}"
eval "UNSHARED_LIB_SUFFIX=${VERSION}${TCL_DBGX}.a"
and pass it through xtoclConfig.sh to the c based
c-components (sdbm, gdbm, expat)
2003-12-08 <Gustaf.Neumann@wu-wien.ac.at>
* Some cleanup in tclexpat.c to make it compile on freebsd
* configure: made --with_gdbm configurable such that
include path and library path can be configured
* Httpd.xotcl: added simple redirects, can be used like e.g.
Httpd h2 -port 9086 -root /tmp \
-redirect {^(mailman|pipermail|cgi-bin)
http://alice.wu-wien.ac.at>:80}
2003-12-07 <Gustaf.Neumann@wu-wien.ac.at>
* incorporated more fixes for build system suggested by Daniel
Steffen
* changed version number to 1.1.1
* further cleanup in Makefiles, reduced redundancy in
distro by using symbolic links
* used everywhere for SHLIB_LD_LIBS XOTCL_BUILD_STUB_LIB_SPEC
instead of XOTCL_STUB_LIB_SPEC
2003-12-06 <Gustaf.Neumann@wu-wien.ac.at>
* httpd.xotcl: fixed return format in HTTP reply header
parameters Allow: and Public: for HTTP OPTIONS method
* library/store/XOTclGdbm/: fixed initialization of
xotcl stubs, usage of ck{free,alloc} vs. {free,malloc}.
* library/store/XOTclSdbm/: fixed handling of O_SYNC on
system that do not have it
* Configure can run now as well from outside of xotcl sources;
One can use now for example the following commands to
compile and install XOTcl
% mkdir -p /tmp/xotcl/unix
% cd /tmp/xotcl/unix
% ~/xotcl-1.1.1/unix/configure --with-all
% make
% make test
% make install DESTDIR=/tmp
2003-12-05 <Gustaf.Neumann@wu-wien.ac.at>
* incorporated changes as suggested by Daniel Steffen
- using consequently DESTDIR for all directory references
- made procs in predefined.xotcl independent
from namespace import ::xotcl::*
- make references relative to $(srcdir) in all Makefile.in
2003-12-02 <Gustaf.Neumann@wu-wien.ac.at>
* added "--with-tkinclude"
* fixed "--with-tclinclude" to set TCL_INCLUDES (for all
subdirs)
2003-11-29 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* release of distribution XOTcl 1.1.0
2003-11-29 <Gustaf.Neumann@wu-wien.ac.at>
* moved tcl command hooks into thread local storage
to fix a bug, when xotcl is loaded into a thread
* fixed various documentation bugs, added style files for
XOTcl tutorial, made presentation more uniform, made
distinction between literals and placeholders visible
* fixed a few issues with purify and mt (many thanks to Zoran!)
* some Makefile improvements (removed the need to generate
documentation on each run of make)
* Fixed compilation issues of expat with tcl 8.3 or younger
2003-11-28 <Gustaf.Neumann@wu-wien.ac.at>
* fixed include path for actiweb components (sdbm and expat)

* added new version of Klaus' securePlaceDemo, some minor
corrections for new XOTcl version
* installed XOTcl library into lib directory under
windows instead of bin
2003-11-26 <Gustaf.Neumann@wu-wien.ac.at>
* removed ::xotcl::lib from predefined variables and from man
page
* added namespace require to xotclsh
* added transparent mixins for instvar
2003-11-25 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: further generalization of call stack entry
skipping; cutFrames can skip now over filters and/or mixins
* "Class new -volatile" works now through filters and mixins
* regression test updated
* reduced size of xotcl distro
* fixed various typos in language reference
2003-11-22 <Gustaf.Neumann@wu-wien.ac.at>

* updated aol-xotcl.tcl (for loading xotcl into aolserver 4.0)
2003-11-20 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* updated documentation:
- added a section "Integrating XOTcl Programs with C Extensions
(such as TK)" to the tutorial
- updated tutorial, readme, compile, compile.win
2003-11-16 <Gustaf.Neumann@wu-wien.ac.at>
* Httpd.xotcl: forced HTTP/1.1 requests over SSL
to use HTTP/1.0 due to a problem between OpenSSL
and certain incarnations of IE.
* Documenting requireNamespace in more detail.
2003-11-13 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* various changes to support conditional shell building with
stubs
* various changes to build libxotcl/xotclsh with tcl 8.0
(stub dependencies)
* Httpd.xotcl: added parameter to web server to
configure timeout for persistent connections
* eliminated a few compiler warnings from xotcl.c
2003-11-12 <Gustaf.Neumann@wu-wien.ac.at>

2003-11-09 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: fixed calling exit-handler twice for threads
2003-11-06 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: simplified handling of command substitutions;
starts to work with Zoran's nstrace.tcl for AOLserver
2003-11-02 MichaelL@frogware.com
* XOTcl Stub lib configure files for C-based extensions.
2003-11-02 <Gustaf.Neumann@wu-wien.ac.at>
* XOTcl intercepts a few commands (info, rename, uplevel and
upvar) and assumed that these commands are defined in C.
Command intercepting was fixed such that intercepting
a proc info works as well; before xotcl produced a core.
Example:
% rename ::info ::tcl::info
% proc ::info args {uplevel ::tcl::info $args}
% package req XOTcl
2003-10-31 <Gustaf.Neumann@wu-wien.ac.at>
* Substituted config/config.sub and config/config.guess
(many thanks to Zoran)
* unix/Makefile.in fixed target install-aol
2003-10-23 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: new proc "__unknown" for Class; whenever
XOTcl references a class, which is not defined yet,
"Class __unknown" is called; this mechanism can be
used to autoload classes in a lightweight fashion
* fixes in the built system to avoid two different
"package ifneeded" (seems to cause troubles under
certain circumstances)
2003-10-20 MichaelL@frogware.com
* Fixed the return value of TclExpatUnknownEncodingHandler
in tclexpat.c. The return value of the handler is now
correctly passed to expat.
2003-10-14 MichaelL@frogware.com
* Changed library names on Windows to make library names more
similar across platforms. Changed xotcl.c and xotclStubLib.c
to support XOTcl stubs. Changed Windows Makefile.vc's to
build all libraries with XOTcl stubs by default. Changed
Windows Makefile.vc's to specify base load addresses for all
libraries. Fixed compiler warnings in winMain.c. Fixed
compiler warnings in tclexpat.c.
2003-10-08 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* a number of changes to make XOTclSdbm and XOTclGdbm work
with xotcl.h solely ... in particular, introduced new stub
functions and Interface structs for XOTclClass and
XOTclObject: XOTcl_Class and XOTcl_Object. Changed XOTcl's
core to expose these in the extern functions that are
exposed via xotcl.decls.
2003-09-10 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* Integrated bug fixes provided by Klaus Kolowratnik
<Klaus.Kolowratnik@wu-wien.ac.at> for the secure http server.
2003-08-27 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* moved config.vc, installWin.tcl to win dir and corrected them
* merged /makefile.vc and /win/makefile.vc; everything for win
now works from the win dir
* adapted other makefile.vc's in distro
* corrected stub table decls and auto generated table .h files
that where incorrect due to recent changes in external API
(XOTclRemoveClass, XOTclAddClass)
* corrected README
* added pkgIndex file for win local dir
* win version change to 1.1
* corrected the wrong local TCLLIBPATH on unix from '$(TOP_DIR)'
to '$(TOP_DIR)/unix $(TOP_DIR)/library' to circumvent the win
dir on the auto_path
* added locale support to xotclAppInit
2003-08-27 <Gustaf.Neumann@wu-wien.ac.at>
* went with spell checker over tutorial and
fixed a hundred of typos
* fixed install of shells
* fixed optional built of xowish (TK_LIB_SPEC was not passed correctly)
* removed obsolete check_library_path in predefined.xotcl
* some fixes in ::xotcl::config mkindex for autoloadine files
2003-08-26 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* doc for precedence order and transitive instmixins in
tutorial
2003-08-25 <Gustaf.Neumann@wu-wien.ac.at>
* Generate library/pkgIndex.tcl from configure
(contains version numbers)
* Fixed script for changing version numbers in xotcl
* Changed version of XOTcl to 1.1.0
2003-08-22 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* Added support for transitive instmixins in xotcl.c,
added test for transitive instmixins
* Various fixes for new build stuff on Windows
2003-08-20 <Gustaf.Neumann@wu-wien.ac.at>
* Fixed configure problem with autoconf coming with RH 9.0
* Allow for the definition of parameters as objects.
It is now possible to have parameters with properties
(See tutorial, section "Objects as Parameter")
* fixed various bugs in the documentation.
MAKE TODO: make rpm, bin-tar, version-change, install-aol
2003-07-13 <Gustaf.Neumann@wu-wien.ac.at>
* Fixed potential crash with shared objects in configure
* First version of object tree creation via parameter
2003-07-11 <Gustaf.Neumann@wu-wien.ac.at>
* extended parameter handling code to support the creation
of parameter objects
* fixed a few documentation bugs
2003-07-05 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: if object is called without method and
arguments, xotcl calls now a method named 'defaultmethod';
the default behavior (defined as an instproc on
Object) is that the name of the object is returned.
Example:
Object o
puts <[o]> ;# outputs <::o>
puts <[o defaultmethod]> ;# outputs <::o>
2003-06-28 <Gustaf.Neumann@wu-wien.ac.at>
* added --with-xotclsh and --with-xowish to create
shell optionally
2003-05-28 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* added "info mixinguard" and "info instmixinguard"
* changed GuardList behavior to tolerate qualified names
* added tests for 'info instmixinguard' and 'info mixinguard'
* made -withGuard and -order work together for "info filter"
on objects.
* checked that guard is deleted, when redefined
with FilterAdd/MixinAdd
* add -guard modifier into filter, mixin definitions and infos
* updated tests
2003-05-23 <Gustaf.Neumann@wu-wien.ac.at>
* removed toplevel configure and Makefile for better
TEA compliance
(configure should be called from xotcl*/unix)
* added --with-actiweb to configure;
(use --with-actiweb=yes to enable it)
* standarized tests (using the same Test classes)
2003-05-16 <Gustaf.Neumann@wu-wien.ac.at>
* removed binary shells and XOTcl's context depending
auto_path setting; consequences:
- in order to invoke xotcl before installation, use
export TCLLIBPATH=`pwd`
in XOTcl's build directory
- instead of using the environment variable XOTCL
(as described in this Changelog on 2001-01-08,
use TCLLIBPATH
* Two small tcl scripts "xotclsh" and "xowish" are provided
for backward compatibility with xotclsh applications
* For interactive use, adding
package require XOTcl; namespace import -force xotcl::*
into your ~/.tclshrc is recommended
* Various changes and simplifications in configure and Makefiles
* XOTclGdbm: fixed it such it works with enable-threads without
crashing immediately
2003-05-12 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* removed various bugs in new code and added tests for
redefinition and removal of filterguards
* added tests for 'instmixinguard' and 'mixinguard'
2003-05-11 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* added new methods 'instmixinguard' and 'mixinguard'
2003-05-09 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* changed the filter, mixin, and guard code to provide a new
composition strategy for (filter- and mixin-)guards, in
case a guard is defined more than once for the same filter
or mixin... now only the most specific guard counts, all
others are overridden by this guard. Example:
Class B -superclass A
A instfilter {{f2 {[self] == "::b2"}}}
B instfilter {{f2 {[self calledproc] == "set"}}}
Here: for an instance of B only the guard on B counts.
* updated the tests accordingly
* performance improvement:
removed ::xotcl::Object from mixin full list computation
* added new tests for mixinguards to testx.xotcl
2003-05-03 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: Changed mixinlist creation from quadratic to linear
(both, in XOTclAddClass and CmdListAdd)
2003-04-29 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: cleanup to avoid potential crashes on error messages
(varargs not terminated by NULL)
* introspection for mixin guards (o|cl info instmixin|mixin
-guards)
* new option for info methods to return only those methods where
the guard holds in the current context (info methods
-incontext)
2003-04-25 <Gustaf.Neumann@wu-wien.ac.at>
* fixed various typos in examples in tutorial
* first implementation of guarded mixins
2003-04-24 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* document "info instdefault" in the language reference
* corrected a problem with move: it did not prevail the
subclass relationships; also added a regression test
2003-04-22 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: calling the "create" method from
the "new" method through the dispatcher (previous version
used a direct call, now create can be overloaded)
2003-04-17 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* Unified ListObjChildren and ListClassChildren into one
method ListListChildren
2003-04-16 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: fixed segfault from classchildren
(many thanks to Michael Cleverly for pointing this out)
2003-04-16 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: Fixed passing of error codes from constructors
(instproc init). In previous releases, errors were
ignored
* xotcl.c: Passing correctly error messages from "set" to the
XOTcl set method.
2003-03-19 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* release of full distribution XOTcl 1.0.2
2003-03-19 <Gustaf.Neumann@wu-wien.ac.at>, Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* release of full distribution XOTcl 1.0.2
2003-03-19 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* changed requireNamespace so that contents of a
Tcl Namespace with the same name as the XOTcl Namespace to
be created survive the requireNamespace invocation & added
tests in testx.xotcl. Example:
namespace eval a {proc o args {puts o}}
Object a -requireNamespace
### -> a::o survives
* some minor issues to everything work with tcl/tk 8.4.2
2003-03-08 <Gustaf.Neumann@wu-wien.ac.at>, Zoran Vasiljevic <zoran@archiware.com>
* some more code cleanup (do not abort when my is called outside
the scope of an object)
* Makefile less verbose
2003-03-07 <Gustaf.Neumann@wu-wien.ac.at>
* Made output of the serializer more compact
(omitting unnecessary references to ::xotcl::Object
2003-03-07 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* Copy/Move to self had undefined or wrong results; corrected
both methods so that the objects stay untouched when copied
or moved to self. Added test in testx.xotcl.
2003-03-04 <Gustaf.Neumann@wu-wien.ac.at>, Zoran Vasiljevic <zoran@archiware.com>
* Made xotcl capable to be loaded via "package require" into
aolserver-4
* To build and install XOTcl for the aolserver-4
the following commands can be used
# cd /usr/homes/zv/tmp/xotcl-1.0.2
# CC=gcc;export CC
./configure --enable-threads --prefix=/var/tmp/aolserver \
--enable-symbols --without-tk --without-gdbm \
--with-tcl=/usr/homes/zv/dev/tcl8.4.1/unix
# make
# make install-aol
This installs libxotcl*.so, the serializer, and the file
xotcl.tcl into aolserver/modules/tcl. The file xotcl.tcl
contains a "package require XOTcl" and "... serializer" and
sources the files aolserver/modules/tcl/*.xotcl
2003-03-04 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: abort, when a non-threaded xotcl version
is loaded into a threaded environment (e.g. aol-server)
2003-02-28 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: fixed a bug the lead to a crash in "self x"
2003-02-20 <Gustaf.Neumann@wu-wien.ac.at>
* fixes to compile xotcl as a module for aolserver-4
2003-02-06 <Gustaf.Neumann@wu-wien.ac.at>
* made -volatile a method rather than an option of the
new method
2003-01-18 <Gustaf.Neumann@wu-wien.ac.at>
* aol-server adjustments (fix the documentation
for new directory structure, update serializer code, testing)
* provided simple replacements for xotclsh and xowish scripts
in the unix subdir for testing purposes (not yet installed)
2003-01-17 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* new directory structure with no version information
* removed pwd from make.xotcl
* new method "ismixin": Test whether the argument is a
mixin or instmixin of the object.
* new method "hasclass": Test whether the argument is either
a mixin or instmixin of the object or
if it is on the class hierarchy of the object.
This method combines the functionalities of
istype and ismixin.
* documented and tested new methods.
2003-01-12 <Gustaf.Neumann@wu-wien.ac.at>
* Changed calls in the form of "[self] method" to "my method"
in 59 files in the xotcl distribution
* changed Serializer to use [list] in configure where necessary
2003-01-09 <Gustaf.Neumann@wu-wien.ac.at>
* configure methods can be placed into a list to avoid
ambiguity of "-". This character is used as a meta-char to
denote method names, but it has to be used in values as well.
Example:
Class Book -parameter {title author}
Book b1 -title "--the title--" -author a.b.c
has to be written as
Book b1 [list -title "--the title--"] -author a.b.c
Note, that XOTcl allows us to provide multiple arguments
to methods called via configure
2003-01-05 <Gustaf.Neumann@wu-wien.ac.at>
* configure returns now the number of preceding elements
without a "-" in its first place. This is needed
for convenient processing of argument lists with trailing
options from tcl.
* avoid processing configure list twice in c code.
2002-12-29 <Gustaf.Neumann@wu-wien.ac.at>
* some cleanup in c-code (to make -Wall slient)
* fixed a bug in the "all" method of the Serializer, changed
package name to "xotcl::serializer"
2002-12-27 <Gustaf.Neumann@wu-wien.ac.at>
* removed deprecated methods "parameters", "applymethods",
"newChild", "newChildOf"
2002-12-23 <Gustaf.Neumann@wu-wien.ac.at>
* release of full distribution XoTcl 1.0.1
2002-12-22 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: some cleanup
* aol-server: improved namespace.tcl (using Serializer)
2002-12-19 <Gustaf.Neumann@wu-wien.ac.at>
* New Serialzer:
- up to 30% faster recreation of objects
- more control of objects or variables to be omitted
- provide mappings for (relative) object names
In general, the Serializer
- is used to generate the blueprint of a workspace
(e.g. in the aolserver)
- can be used migate objects between threads
- to cache objects in the aol-server

2002-12-18 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: new predefined method 'noinit'
can be used to create an object without calling its
constructor (used in the serializer to recreate objects
from a snapshot)
2002-12-17 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* installWin.tcl: correction for patchlevel
* changed version to 1.0.1
2002-12-14 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c fixed a bug in "info default arg var" and
"info instdefault arg var" in connection with filters.
The output variable was created in the filter frame.
Many thanks to Oumung Mehrotra for reporting the problem.
* New switch for compilation USE_ASSOC_DATA to use Tcl_AssocData
instead of namespace client data for the runtime state
(without assoc data, 10-15% faster)
2002-12-06 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* changed recreate semantics: recreate now calls the cleanup
method; so that one can preserve object information in the
recreate, call next (and do the cleanup), and finally handle
the correction for recreation.
* tutorial: added example of structure preserving recreate and
updated langRef.xotcl accordingly
2002-11-22 <Gustaf.Neumann@wu-wien.ac.at>
* fixes in documentation
* automatic generation of pdf files and make target
for the tutorial and the language reference
2002-11-19 <Gustaf.Neumann@wu-wien.ac.at>
* fixes for configure for aolserver 3.5.*
2002-11-13 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* correct check for XOTcl lib on auto_path in predefined.xotcl;
it was checked for xotcl$VERSION, should be xotcl$VERSION
2002-11-08 <Gustaf.Neumann@wu-wien.ac.at>
2002-11-08 Uwe Zdun <uwe.zdun@uni-essen.de>
* Win makefile.vc: let nmake install call the install script

2002-10-30 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* fixes for tcl 8.0.5
2002-10-28 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* used a proc for exit handler (instead of Object variable),
old interface for exitHandler does still work
* eliminated a mem leak in FilterFindReg as indicated by
Zoran.
2002-10-26 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: fixed problem with external symbol for
cmdType and reactivated KEEP_TCL_CMD_TYPE for all
tcl versions
2002-10-25 Zoran Vasiljevic <zoran@archiware.com>
* xotcl.c: fixed memory leak for new method.
2002-10-23 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* Object instproc extractConfigureArg: get one configure argument
(and possibly cut it) from a given args list. Especially used in
create before init is called with next to get args
before the object is actually created (& documentation).
2002-10-22 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* used Tcl's Assoc structures for runtime state
2002-10-21 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* corrected "abstract" next handling in predefined.xotcl
2002-09-19 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: prevent duplicate destroy calls during cleanup
* xotcl.c: error in exit handler does not panic anymore, but
writes to stderr (panic can't be used when exit handler
is called by a thread)
* Serializer.xotcl: {Serializer all] return exit handler
as well.
2002-09-14 <Gustaf.Neumann@wu-wien.ac.at>
* Trace.xotcl: fixed typos in documentation code, changes
for "my".
2002-08-29 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* corrected findXOTcl.c: it got confused by an toplevel
XOTcl dir, like: ~/xotcl-1.0/x/xotcl-full-1.0 and didn't find
the libs then.
2002-08-27 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* disabled KEEP_TCL_CMD_TYPE for 8.4, as it did not compile for 8.4b1
2002-08-04 <Gustaf.Neumann@wu-wien.ac.at>
* Httpd.xotcl: order directories before files in directory
listings
2002-07-18 <Gustaf.Neumann@wu-wien.ac.at>
* Httpd.xotcl: fix for handling broken links
2002-07-12 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* Win fixes for compilation with Tcl 8.4b1
* fixed mem leak of filter search
2002-07-10 <Gustaf.Neumann@wu-wien.ac.at>
* fixes for compilation with Tcl 8.4b1
2002-07-06 <Gustaf.Neumann@wu-wien.ac.at>
* Fixed a compilation bug concerning Tcl 8.2 and younger
2002-05-30 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: fixed destroy bug, when object was destroyed
during init
* xotcl.c: minor cleanup
2002-05-16 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* xotcl.c: searching filter start commands again, if order is
invalidated. Otherwise filter commands of de-registered mixins
persist to be a filter. If no other filter or instfilter with
the name is found, the filter entry is removed from the filter
list.
2002-05-15 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* COMPILE: an explicit sentence in the beginning that you need
Tcl/Tk sources to compile XOTcl.
* xotcl.c: FilterSearch has only search for object-specific
filters in the object's current order ... that was a bug. It
has to search for filters on mixins and instmixins as they are
specified by filter and instfilter. fixed.
* xotcl.c: Filter application order was: object filters -> mixin
filters -> class filters. Corrected to mixin filters -> object
filters -> class filters. Now it conforms to the order on
normal dispatches.
* xotcl.c: changed fatal abort to error, when self is called
without an active object
2002-05-05 <Gustaf.Neumann@wu-wien.ac.at>
* fixed UTF-8 conversion for filenames
2002-04-30 <Gustaf.Neumann@wu-wien.ac.at>
* Httpd.xotcl: minor cleanup (removed superfluous instvars)
* xotcl.c: removed incr/decr refcount on cl-names in DoDispatch
2002-04-21 <Gustaf.Neumann@wu-wien.ac.at>
* fixed a bug in path settings:
when xotclsh was called from an xotcl source directory where
no libxotcl*.so was located (e.g. before a compile) an error
was produced during load; xotclsh checks now whether it can
locate the .so file before setting the path.
2002-04-20 Uwe Zdun <uwe.zdun@wu-wien.ac.at>
* fixed a bug in filter code (recursion blocking)
2002-04-20 <Gustaf.Neumann@wu-wien.ac.at>
* Http client code: fixed several small bugs:
- url composition
- error handling
- redirects to different ports
2002-04-09 Uwe Zdun <uwe.zdun@uni-essen.de>
2002-04-09 <Gustaf.Neumann@wu-wien.ac.at>
* finshing rpm and bin-tar generation
* patch release of full distribution (0.9.4)
2002-04-08 <Gustaf.Neumann@wu-wien.ac.at>
* fixed a bug in copy/move (the constructor was called during
copying without instvars etc.; now the construcor is not
called here) Many thanks for Artur Trzewik for noting this.
2002-04-08 Uwe Zdun <uwe.zdun@uni-essen.de>
* fixed .add files for Windows
2002-04-07 <Gustaf.Neumann@wu-wien.ac.at>
* removed persistence dir in actiweb regression test to achieve
same behavior on each run of the test
* Storage.xotcl: fixed a bug when new persistence directories are
created
* fixed a small memory leak in autonames
2002-04-05 <Gustaf.Neumann@wu-wien.ac.at>
* defined the following policies for excplicit freeing in the
exit handler:
NO_CLEANUP for processes, the physical free in the exit handler
is not needed
CLEANUP for threads, just the xotcl classes/objects with
its instvars are reclaimed, annother
mechanism should take care of the global
procs and vars (automatically choosen, when
compiled with TCL_THREADS)
FULL_CLEANUP for testing purposes, to check, whether xotcl
has memory leaks; all global procs and vars
are deleted as well.
2002-04-04 <Gustaf.Neumann@wu-wien.ac.at>
* fixed a bug with duplicated tcl_objs of XOTclObjectType
that could cause double frees.
2002-04-02 <Gustaf.Neumann@wu-wien.ac.at>
* Less agressive converison to tcl_objs of XOTclObjectType.
It will try to keep objects of type tclCmdType when
KEEP_TCL_CMD_TYPE is activated during compilation (default).
2002-03-28 <Gustaf.Neumann@wu-wien.ac.at>
* horrible bug fixed, when USE_ALLOCA or USE_MALLOC
was defined (macro substitution lead to wrong arithmetic).
These macros were defined for c-compilers that do not
support variable sized arrays as local variables. Gcc
were always fine, but e.g. under the standard AIX compiler
array boundaries were overwritten... I wonder, why we have
seen no bug reports, this bug was in since ages....
2002-03-27 Zoran Vasiljevic <zoran@archiware.com>
* more code for volatile objects moved to C
2002-03-26 <Gustaf.Neumann@wu-wien.ac.at>
* Fixed a few more places, where recounted xotcl-objects
can cause troubles (mem-leaks + invalid pointers)
2002-03-24 <Gustaf.Neumann@wu-wien.ac.at>
* auto-deletion of global vars and proc to
get rid of references to xotcl-objects for deletion
2002-03-20 Uwe Zdun <uwe.zdun@uni-essen.de>
* added reference counts for xotcl objects to
avoid crashes for recreated objects (thanks for
Artur Trzewik for sending a good bug report)
2002-03-11 Zoran Vasiljevic <zoran@archiware.com>
* xotcl.c: fixed XOTclReplaceCommand for AOL-Server
(multi threading bug)
2002-03-11 <Gustaf.Neumann@wu-wien.ac.at>
* Httpd.xotcl: fixed relative pathname-bug for basic authentification
2002-03-02 <Gustaf.Neumann@wu-wien.ac.at>

* HttpPlace: added Pragma no-cache for dynamic contents
* overworked persistence manager to separate storage
specific concerns (like directory checking) from generic ones
* new storage manager multi-storage to multiplex storage
requests to multiple sinks.
2002-01-10 Uwe Zdun <uwe.zdun@uni-essen.de>
* removed duplicated system library in library/system. The correct
one is in xotcl-XXX/library!!
2002-01-09 <Gustaf.Neumann@wu-wien.ac.at>
* fixed path determination code during
startup to avoid "cant read 'pf'" messages
2002-01-08 Uwe Zdun <uwe.zdun@uni-essen.de>
* introduced bcc (copy) database option for persistent databases and
configuration option for db file names and dirs in actiweb
places
* xotcl.c: found and fixed a small bug in unknown:
Object o; o r
with no unknown defined has looped (not for class -> unknown).
corrected it and added it to testx.xotcl
2002-01-06 <Gustaf.Neumann@wu-wien.ac.at>
* further improvement of bytecode compilation
* new bytecode instruction SELFDISPATCH
* methcall benchmar now more than 40% faster than in 0.9.3
* some cleanup in xotcl dispatch code
* fixing external references for symbols not starting with xotcl
2002-01-02 <Gustaf.Neumann@wu-wien.ac.at>

and initProcNS. Speedup for the oo-shootout
+ methcall 30%
+ objinst 9%
some tests are now twice as fast than before, self is
now 10 times faster (about 1 microsecond on a 600 MHz PIII)
2001-12-28 <Gustaf.Neumann@wu-wien.ac.at>
* fixed changeXOTclVersion, made more generic
* fixed Agent migration, made all migrations synchronous
(for the time being)
2001-12-17 Uwe Zdun <uwe.zdun@uni-essen.de>
2001-12-17 <Gustaf.Neumann@wu-wien.ac.at>

build process, use Tcl stub lib, and make shells
only shallow wrappers that load the XOTcl package
on demand
2001-10-23 <Gustaf.Neumann@wu-wien.ac.at>
* removed code for calling variable command
2001-10-22 <Gustaf.Neumann@wu-wien.ac.at>

to a link var
2001-10-15 <Gustaf.Neumann@wu-wien.ac.at>
2001-05-15 Uwe Zdun <uwe.zdun@uni-essen.de>
* XOTcl 0.9 Release
2001-10-14 <Gustaf.Neumann@wu-wien.ac.at>
* new method of Object: parametercmd:
a convenient way to define a new getter/setter for
individual objects (similar to parameters for classes)
* polishing docu
2001-10-11 <Gustaf.Neumann@wu-wien.ac.at>
* improved make clean
* fixed incompatibilities in various
scripts distributed with xotcl
2001-10-11 Uwe Zdun <uwe.zdun@uni-essen.de>
* configure.in: fixed that --without-tk functions
ensured that user-defines with --with-tcl/tk
override found settings.
* xotcl.c:
- conditional for different TclIncrVar2 interfaces
in Tcl 8.05 and Tcl 8.3
- added TCL_PARSE_PART1 to variable lookup in
GetInstVarIntoCurrentScope. TclLookupVar in 8.05
requires it for looking up arrays with only part1
given.
2001-10-10 <Gustaf.Neumann@wu-wien.ac.at>
* fixed autoname method for Tcl 8.0.5
2001-10-10 Uwe Zdun <uwe.zdun@uni-essen.de>
* finished polishing mem leaks (thanks to Zoran Vasiljevic again)
* disallowed "[self] next" ... next is now only a command
* Gdbm,Sdbm,Expat: corrected Makefile.in to rely on
-L$(TCLLIBDIR) (thanks to J�rg Rudnik for the hint)
2001-10-08 <Gustaf.Neumann@wu-wien.ac.at>
* configure.in: fixes for AOLSERVER to ease configuration
* aolstub.c: fixes for namespace handling (XOTcl is
now a "well behaved" Tcl extension)
2001-10-05 Uwe Zdun <uwe.zdun@uni-essen.de>
* added PRESERVE and RELEASE functions for Tcl_Objs so that
we remember all Tcl_Objs that are temporarily allocated,
otherwise the ExitHandler would not free Tcl_Objs, like:
INCR_REF_COUNT(tclobj);
callaMethodContainingExit(); /* "exit" call */
DECR_REF_COUNT(tclobj); /* not reached */
* corrected filtersearch and procsearch to return the new
proc qualifier format:
<objName|classname> proc|instproc <methodName>
as a Tcl list. filtersearch does now operate on objs as well,
procsearch does support mixins now. Added tests for both.
* documented new features in tutorial and langRef
2001-10-04 Uwe Zdun <uwe.zdun@uni-essen.de>
* minor fixes to get WIN version to run again
2001-10-03 Uwe Zdun <uwe.zdun@uni-essen.de>
* removed some more mem leaks,
* reworked exit handler to destroy metaclasses and operate on a
instance list, instead of namespace cmdTable
* pop remaining callstack entries in ExitHandler to prevent
from false deletion order, if "exit" is called from within a
method
* changed XOTclErrInProc not to rely on obj/class Tcl_Obj*
so that we do not have to preserve them in DoDispatch
(mem problem)
2001-10-02 Uwe Zdun <uwe.zdun@uni-essen.de>
* added a optional simple mem counter functionality. DEFINE
XOTCL_MEM_COUNT so that you get a mem count dump after exit.
* removed some mem leaks
2001-10-01 Uwe Zdun <uwe.zdun@uni-essen.de>
* new info option "info methods" ... returns all methods (procs
and cmds) defined along the hierarchy for an object.
accepts modifiers: -noprocs, -nocmds, -nomixins
2001-09-30 Uwe Zdun <uwe.zdun@uni-essen.de>
* don't allow duplicates in filter/mixin structures (e.g. info
filter has returned "b c b", now the filter appears only
once. Filterguards are merged into one guard.
* new modifier "-order" for info filter and info mixin ->
returns order on a particular object, for filters with
syntax "<obj/cl> proc/instproc <procName>" for mixins just a
class list
2001-09-26 <Gustaf.Neumann@wu-wien.ac.at>
* cleanup, removed a few bugs
* new instproc for Class: insttclcmd <name>
creates an instmethod with the given name
that calls the Tcl command with the given name in the
variable environment of the object
* renamed instproc of Class parameteradd to: instparametercmd
* xotcl.c: more complete set of tracing options for debugging
* some speedups:
- instcommand array, append, lappend trace
are now more than 3 times faster than before
(through insttclcmd)
- condition checking (for pre and post conditions and guards)
is as well more than 3 times faster than before
* configure.in: made -Wall conditional for gcc
2001-09-25 Uwe Zdun <uwe.zdun@uni-essen.de>
* merge with <Gustaf's version
2001-09-23 <Gustaf.Neumann@wu-wien.ac.at>
* xotcl.c: new XOTclObject member "flags", which
is a bitmap for various object states
(isClass, isDestroyed, etc.). Defined several
according macros XOTclObjectIsClass(obj),
XOTclObjectToClass(obj), etc.
* revitalized Tcl_Obj of type XOTclObj to speedup
access of Objects and classes by using
GetXOTclObjectFromObj
GetXOTclClassFromObj
(speedup of create by 15%, a few simple commands
are now more than twice as fast (Object isclass))
2001-09-20 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c:
- made objectData structure optional and moved
functions into file xotclObjectData.c
use XOTCL_OBJECTDATA to compile it in
- moved obj & cl clientDatas into optional memory, new extern
getter/setter functions: XOTclSetObjClientData,
XOTclGetObjClientData, XOTclSetClassClientData,
XOTclGetClassClientData. Used them in persistence store
wrappers xotclSdbm.c & xotclGdbm.c
* testx.xotcl:
- Added some obj filter tests
2001-09-19 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c:
- added "opt" structures to XOTclObject and XOTclClass so that
optional info (filters, mixins, asssertion,...) is only
allocated on demand
- corrected bug ... search for epoched filter cmd in
FilterRemoveOnObjFromCmdPtr also in mixins
- added flags to XOTclObject instead of filterDefined,
mixinDefined, and destroyCalled shorts
2001-09-18 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c: removed object reference code ... I guess we won't do
references this way
2001-09-17 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c: added new instcommand "vwait" on object that mirrors
the behavior of Tcl's vwait, but does not operate on flag
TCL_GLOBAL_ONLY. The new xotcl obj var tables do not operate with
that. E.g.:
Object instproc vwait {varName} {
[self] instvar $varName
::vwait [list $varName]
}
would wait for a global variable varName ... though:
Object instproc vwait {varName} {
[self] requireNamespace
::vwait [self]::[list $varName]
}
should work ...
* xotcl.c: info classparent now returns object name of class, not
::xotcl::classes***
* xotcl.c: new method "objeval" on Object. It executes an command
in the scope of an object. This is an important convenience
method because something like:
Object instproc lappend {varName args} {
[self] instvar varName
eval ::lappend [list $varName] $args
}
is problematic if the object has a namespace and varName is an
array element ... then Tcl does want to upvar it (was also
present in all earlier xotcl versions ... we have used an
instvar alias then). Now we can do:
Object instproc lappend {varName args} {
[self] objeval [concat ::lappend [list $varName] $args]
}
This is easier an faster than using an alias ...
2001-09-16 Uwe Zdun <uwe.zdun@uni-essen.de>
* predefined.xotcl:
- new method "trace" on Object ... simple forwarder to tcl's trace
- eliminated "cset" on Object and from the distribution, seems to
be nearly unused
* whole distr:
- replaced direct namespace variable accesses with [self] or
instvar accesses. Here's what I did:
(a) grep for <[self]::>
(b) grep for <info exists> plus <::> together in one line
(c) grep for <}::> to get e.g. ${a}::b
that should find most occurrences of variable namespace access,
except for direct accesses like: set y::x, where y is an object
name and c a variable to be set.
2001-09-15 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c:
- Namespaces of objects are now created only on demand,
that is when:
- obj proc is created
- obj command is created with XOTclAddPMethod
- child is created on the object
Note that this is a prominent change. Especially it saves a
significant amount of memory allocation per object. But you
cannot assume the existence of object namespaces anymore.
That means:
Object o
set o::var 1
returns TCL_ERROR: parent namespace does not exist. Use
o set var 1
instead. Same appears for append, lappend, trace, array and
other Tcl variable handling commands.
"info exists" is problematic because it does not return an
error message:
Object o
o set i 1
info exists o::i
returns 0.
It is save to use all Tcl command together with instvar.
- new method "requireNamespace" on Object. Creates an object
namespace explicitly.
- new info option "hasNamespace" on Object: returns 1, if the obj
currently has a namespace, otherwise: 0.
- eliminated "returnCode" on RUNTIME_STATE due to several bugs,
why was it there???
2001-09-14 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c:
- Changed XOTclCInfoMethod to be based on two switch statement
instead of ifs. Let List* functions return the state (such
as TCL_OK).
- introduced code for modifiers in info methods. Modifiers are
"-" options that change the behavior of an info method
- introduced -guard modifier for filter and instfilter (it
prints a filter list with guards)
2001-09-13 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c:
- eliminated some flaws in filterguards
- forbid "new" filtering during checking a filterguard
2001-09-06 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c:
- also allowed instfilters on a mixin class of an object
2001-09-03 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c:
- bug corrected: filter correctly removed from all dependent
classes when filter proc is deleted or superclass is changed
- bug corrected: added cmdEpoch check on computation of full
filter/mixin lists
2001-09-03 <Gustaf.Neumann@wu-wien.ac.at>
* various cleanup and fixes due to new features
2001-09-03 Uwe Zdun <uwe.zdun@uni-essen.de>
* testx.xotcl:
- filterguard tests
* xotcl.c:
- bug corrected: filter order invalidation upon new proc/instproc
... for filter inheritance
2001-08-25 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c:
- new filter guards language construct for constraining filter
appliance
- introduced generic Tcl_obj* list instead of
XOTclAssertion*,
2001-08-24 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c:
- CallStackGetFrame: iterate only over INACTIVE filters (was a bug)
- self filter & mixin infos: determine info position from
callstack with CallStackGetFrame, so that uplevel functions with
[self calling*,called*]
- NextMethod: passed XOTCL_UNKNOWN through at end of mixin/filter
chain, if no method was found.
* testx: added tests for these corrections.
2001-08-23 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c and tests: added initProcNS command executed at
beginning of all XOTcl procs/instprocs ... it prevents from
jumping to the object's namespace, when a proc is opened.
Now:
namespace eval html {
Object o
o proc t {} {puts ns=[namespace current];li}
o t
}
results in:
li
ns=::html
Now inside of a namespace, like ::Object, you can call global
methods, like ::set without preceding "::" ...
=> Incompatibility to former versions: direct XOTcl proc
calls, like:
Object rp
rp proc time {cmd time} {...}
rp proc x {
time "set x 3" t
}
are invalid ... you have to write:
rp proc x {
[self] time "set x 3" t
}
2001-08-20 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c and all tests: moved Object, Class, and @ into ::xotcl
namespace, now
namespace import -force xotcl::*
has to be written at the beginning of each script to have
them in the global namespace.
- info options now return ::xotcl::Object, ::xotcl::Class, and
::xotcl::@
- direct sets and unsets of variable are not possible anymore:
"Object set a 5" functions, but not "set Object::a 5",
but "set xotcl::Object::a 5" is ok
2001-08-20 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c and all tests: moved xotcl classes from ::XOTclClasses
to ::xotcl::classes
2001-08-20 Uwe Zdun <uwe.zdun@uni-essen.de>
* Actiweb -> made it run with new filter code ... what you have to
change on your existing code to make it run:
1. change all invocations of "filter" to "instfilter"
2. same for "info filter" to "info instfilter"
3. same for "filterappend" to "instfilterappend"
4. for all filters on metaclasses: you must not provide the
metaclass name anymore, the filter finds it
automatically, say, if you have a metaclass C and a
filter f, you had to write:
A filter C::f
now this is
A instfilter f
5. replace regclass with [lindex [self filterreg] 0] ...
may be changed again

clashes, in 0.85 they will probably be used as basis for a
hierarchical component model.
2001-03-05 Uwe Zdun <uwe.zdun@uni-essen.de>

behavior of class and instmixin.
2001-02-06 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c, testx.xotcl, ...: tests for new destroy logic

* packages/store/XOTclSdbm: sdbm wrapper for XOTcl
2001-01-08 <Gustaf.Neumann@wu-wien.ac.at>
* The search for the XOTcl library is performed according to the
following rules:
1) If the environment variable XOTCL is set and points to a
directory, it is taken as the XOTCL directory.
2) If the auto_path (determined in part by the environment
variable TCLLIBPTH) contains a directory named "xotcl"
and it exists, it is taken.
3) If no xotcl library is determined yet, check
whether the current directory is in an xotcl source tree. If
yes take it.
4) If the auto_path contains a directory, that has a
sub-directory named xotcl, it is taken.
5) If the auto_path contains a directory that has a
directory named xotcl as a neighbor, it is taken.
6) Take the compiled-in path for the xotcl library.
After the search for the XOTcl library the global Tcl
variable ::xotcl::lib is set to the determined directory. This
directory is added automatically to the ::auto_path if
necessary.

!! xotcl.c removed aggregation short form due to incompatibilities
with unknown. I.e.,
[self] Class x
does not function like
Class [self]::x
anymore, but triggers the unknown mechanism.
* removed bug: parameters have tried to call "-1"
default value as method
2000-09-26 Uwe Zdun <uwe.zdun@uni-essen.de>
!! src/xotcl.c: short form for creation of nested object and
classes removed.
* new documentation tool
2000-09-22 <Gustaf.Neumann@wu-wien.ac.at>
* new configure flags:
--with-gdbm=INCDIR,LIBDIR
--with-tk=INCDIR,LIBDIR
--with-tcl=INCDIR,LIBDIR
2000-09-19 <Gustaf.Neumann@wu-wien.ac.at>
* apps/actiweb-apps/FormsWithState.xotcl:
new example script for implementing a multi-page form
which keeps the state in a context object, which
is passed from form to form via hidden form fields
* new toplevel configure file
* toplevel "make install" copies demo apps as well
(should we set the path to xotclsh in first line?)
2000-09-13 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c: added new format functionality to autoname. %
strings are now recognized as in the Tcl "format"
command. E.g.: autoname a%06d --> a000000, a000001, a000002, ..
* rdf/xoRDF.test, rdf/RDFTriple.xotcl: used new autonames here
in order to make triples sort-able with lsort
2000-09-12 <Gustaf.Neumann@wu-wien.ac.at>
* Httpd.xotcl: Fixed a bug for IE5.5 with persistent connections:
(Server blocked); cause: the Tcl command "fcopy" alters the
blocking state of a socket when it finishes (bug in fcopy
of tcl 8.3.2)
2000-09-12 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl/src: added xotclInt.h as XOTcl internal API
(still incomplete)
* xotcl.c:
- extracted xotclProfile.c, xotclReference.c, xotclTrace.c,
and xotclError.c from xotcl.c,
- started conversion to Tcl-like naming convention for
functions: XOTcl... for internal API,
XOTcl_... for external API
2000-09-07 Uwe Zdun <uwe.zdun@uni-essen.de>
* xoXML.xotcl: removed need for empty topNode
* xoRDF.xotcl/RDFTriple.xotcl: Uniform Parse Tree
- abbrev properties and parseType = resource are now parse
into descriptions
- class hierarchy uniformized to resources and properties
... object names
are either prop.. or res..
- resource types are stored in rdftypes variable
(as a list of types)
- Typed nodes are parsed into description + type
- namespace definition at RDF tag recognized
- hard coded "rdf:" removed (now rdfNSPrefix is stored on
each node, the parser has a rdfNamespace parameter)
2000-09-06 <Gustaf.Neumann@wu-wien.ac.at>
* packages/store/Persistence.xotcl: lazy open for
persistence database added (to avoid creation of not needed
files, when no persistent variables are used, and to reduce
permission problems for creation, opening, etc)
2000-09-04 Uwe Zdun <uwe.zdun@uni-essen.de>
* xotcl.c, Makefile.vc: INST_XOLIBPKG, XOTCLVERSION passed to
VC 6.0 preprocessor from Makefile.vc (thanks to David
LeBlanc for the fix)
2000-09-04 <Gustaf.Neumann@wu-wien.ac.at>
* xoRDF: trivial fix for make numbering of anonymous resources
easier to comprehend
* predefined.xotcl: methods "append" and "lappend" added
* xotcl/Makefile: keeps track of configure.in and reconfigures
if necessary (eg. version change)

-instance)
2000-08-31 Uwe Zdun <uwe.zdun@uni-essen.de>

* toplevel Makefile: target "make test" added
2000-08-16 <Gustaf.Neumann@wu-wien.ac.at>
* RDFTriple got a new method "prettyTriples" which uses
indentation to show connections between triples (used in xoRDF.test)
2000-08-11 <Gustaf.Neumann@wu-wien.ac.at>
* apps/xocomm/webserver.xotcl listens on port 9086 as well
to test basic access control
* packages/make.xotcl -test added
* Access.xotcl: fixes for credentials, timing for SimpleRequest now optional
(-timing 1, default is -timing 0)
* new files: packages/comm/xocomm.test, packages/rdf/xoRDF.test
* Ftp fixed for now Access methods
* "Class instproc newChild" and "Class instproc new" added
2000-08-09 <Gustaf.Neumann@wu-wien.ac.at>

* all internal calls to destroy handled by a single
function "callDestroyMethod"

(needs free program xref to be installed)
2000-08-08 <Gustaf.Neumann@wu-wien.ac.at>
* new instcommand "exists" to check whether a variable
exists (no need to use namespaces or instvar to check
for the existence of variables)
* xotcl.c: using new macros
VarFrameDecls
VarFrameSwitchToObj(in,obj)
VarFrameRestore(in)
to change VariableFrames
(speedup mand making code more uniform)

(no ":", no "::", no ":[^:].+", no ".+:", no ".*NAME::[:]+NAME")
* copy and move methods create no invalid names that must be fixed
by Object creation
!! methods called via "-" syntax must start with an alphanum character
* Object creation 10% faster
* apps/actiweb-apps/MC.xotcl uses POST instead of GET

-----------------------------------------------------------------------------
2000-06-05 XOTcl 0.81 Release -- Major Changes to Version 0.80
- changelog started by Uwe Zdun

- deep copy/move with all language features
- renamed "parameters" to "parameter"
- renamed "info filters" and "info mixins" to "info filter"/
"info mixin"

- 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

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

* 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
