2007-06-05: * Fixed spelling mistakes in the tutorial (Many thanks to Robert Hicks for reporting) 2006-11-25 * Release of XOTcl 1.5.3 2006-11-24 * 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 , Uwe Zdun * Release of XOTcl 1.5.2 2006-09-28 * 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 * 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 " 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 * 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 * xotcl.c: make sure, that no Tcl_SetIntObj(Tcl_GetObjResult(interp), 1); happens on shared objects. 2006-09-22 , Uwe Zdun * Release of XOTcl 1.5.1 2006-09-22 * 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 * 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 * 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 * 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 * 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 * fixed a bug in deprecated part, when -setter is used in parameter options. 2006-09-15 * 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 , Uwe Zdun * Release of XOTcl 1.5.0 2006-09-13 Uwe Zdun * Update of build files for windows 2006-09-10 * 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 * 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 * provided Tcl 8.5a4 compatibility * spellechecking langref, make terminology more consistent (naming of arguments like .e.g methodName) 2006-09-04 * update of tcl.m4 for newest TEA from CVS 2006-09-03 * "mixin|filter|instmixin|instfilter set ..." deprecated, use "mixin|filter|instmixin|instfilter assign ..." instead 2006-09-01 * fixed a bug in the xotcl trace module (many thanks to jima for reporting) * extended procsearch to report parametercmd and instparametercmd 2006-08-30 * extended procsearch to report as well [inst]parametercmd 2006-08-26 * extended procsearch to report as well [inst]forward and [inst]cmd 2006-08-25 * new subcommand "info slots" * implemented backwards bug-compatible "info parameter", deprecated 2006-08-23 * added system slots and attribute slots (see documentation) 2006-08-21 * 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 * 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 * new command for registering predefined C-implemented Tcl commands as methods ::xotcl::alias | \ ?-objscope? ?-per-object? "-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 * 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 * 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 * 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 * deprecated command filterappend, instfilterappend, mixinappend, instmixinappend, tclcmd, insttclcmd deleted 2006-03-20 * allow single colons in method names (fix in xotcl.c, NSTail()) 2006-02-17 , Uwe Zdun * release of 1.4.0 2006-02-17 * fixed a bug with nonpositional arguments in connection with "args" (Many thanks for Kurt Stoll pointing this out) * added more regression tests * fixed dependencies created for rpm binaries * mak compile cleaner for gcc 4.* under linux 2006-02-08 Uwe Zdun * fixed a bug with transitive mixins 2006-02-02 * Upgrade to TEA 3.5 2006-01-10 * fixing exit behavior with variable traces in multi-threaded environments (volatile objects could be demalloced twice before) 2006-01-08 * allowing tcl commands and variables as default values for parameters; previously, only one-word commands were allowed. 2006-01-07 * ::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 * unsetting the global variable "cmd" from predefined.xotcl (Many thanks to Koen Danckaert for reporting) 2006-01-05 , Uwe Zdun * fixing incorrect state in filters after next * extended regression test 2006-01-02 * info children returns true children, no namespace imported objects/classes * extended regression test 2005-12-20 * upgrading configure scripts of subcomponents to TEA 3.4 2005-12-17 * fixing missing omitted message for unknown subcommand to self 2005-12-07 , Uwe Zdun * release of 1.3.9 2005-12-06 * 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 * Upgraded TEA to 3.4 * updated rpm build (many thanks to Ildiko Schmidt and Alexander Bergolth) 2005-11-28 * 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 * require automatically a namespace when a childobject is added 2005-11-18 * new switch -nocomplain for "mixin|instmixin|filter|instfilter delete" to avoid error messages when deleting entries not there (similar unset) 2005-11-10 * " 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 * new subcommand of self: [self args] return the full argument list of the current call 2005-10-02 , Uwe Zdun * release of 1.3.8 2005-10-01 * 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 * fixed bug in instvar (many thanks to Koen Danckaert for the report) extended regression test 2005-09-27 , Uwe Zdun * release of distribution XOTcl 1.3.7 2005-09-26 * 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 * 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 * Fixing serializer to enforce methods on ::xotcl::Object or ::xotcl::Class before other objects and classes 2005-09-13 * adding two package require into library files (many thanks to Andreas Kupries for the report) 2005-09-09 * fixing various namespace issues in library files to make regression test working again. 2005-09-08 * 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 * 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 * code cleanup: removed ifdefs for TCLCMD 2005-08-04 * 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 * prevent new from overwriting an existing object (increment further until unused name is found) 2005-07-04 Jeff Hobbs * providing update for configure 2005-04-04 * 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 * 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 , Uwe Zdun * release of distribution XOTcl 1.3.6 2005-03-16 * 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:
