2007-10-28: * some code refactoring * making new code more robust 2007-10-23: * First version of new info methods "mixinof" and "instmixinof" - new class info options: mixinof instmixinof - on class destroy entry is now removed from mixin and instmixin lists 2007-10-12: * Release of XOTcl 1.5.6 2007-10-09: * 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: * 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: * 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: * Fix for cases, where volatile objects are deleted before the corrsoponding trace variable. 2007-09-18: * Release of XOTcl 1.5.5 2007-09-18: * Fix rpm build (most probably due to TEA 3.6) 2007-09-13: * Use AssocData instead of the clientdata of the global namespace to store the XOTcl interpreter's 2007-09-13: * Upgrade to TEA 3.6 2007-09-10: * Make forward option -earlybinding more robust, when forwards are done to Tcl procs 2007-08-16: * 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: * Release of XOTcl 1.5.4 2007-08-10: * fixed regression test in rdf-tests (introduced due to autoname changes in 1.4.0) 2007-08-10: * Fixing bugs introduced by VarReform * Extending regression test to handle the cases 2007-08-07: * 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: * 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: * 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: * 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 * Pre-Release of XOTcl 1.5.4 2007-07-23: * fixed a bug with empty argument names (Many thanks for Stefan Sobernig for reporting the bug) 2007-07-03: * 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: * Fixed spelling mistakes in the tutorial (Many thanks to Robert Hicks for reporting) 2007-05-27: * Fixed potential error with default values for parameters starting with a "-". (Many thanks to Shishir Ramam for reporting) 2007-03-16: * 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: * fixing error message propagation for methods called via configure. (Many thanks for Kristoffer Lawson for reporting the bug) 2006-12-12 * changing "test == " to "test =" as required by FreeBSD (many thanks to Martin Matuska for providing the patch) 2006-12-07 * MinGW patches (many thanks to Martin Matuska for providing the patch) 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: 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 * improved documentation in tutorial, als syntactically such that htmldoc 1.8.24 works with it * extended regression test, reduced dependency on tests 2005-03-11 * 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 * improved documentation of next in langRef 2005-02-23 * fixed passing of error code from init methods (thanks to Fabrice Pardo for noting it) * returning PACKAGE_VERSION after a package require (e.g. 'package req XOTcl' returns now 1.3.6) 2005-01-15 , Uwe Zdun * release of distribution XOTcl 1.3.5 2005-01-10 * added instproc for ::xotcl::Class allinstances to return all instances for the actual class 2005-01-07 * 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 * 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 * 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 * fixed crash for empty arguments (thanks to Gerald Stermsek for reporting this bug) 2004-12-02 , Uwe Zdun * release of distribution XOTcl 1.3.4 2004-12-02 * changed metadata analyser from recursive to iterative 2004-11-30 * various fixes to improve portability 2004-11-27 , Uwe Zdun * release of distribution XOTcl 1.3.3 2004-11-20 * fixed [self callinglevel] in nested uplevel loops in the presence of filters, extended regression test 2004-11-19 Uwe Zdun * fixed bug: empty non-pos args, double dash alone. Thanks to Bryan Schofield for reporting this bug. Added tests. 2004-11-18 * changed internal communication between end-of-filterchanin and "unknown" to flag instead of return code XOTCL_UNKNOWN * fixed [self callinglevel] in nested uplevel loops (many thanks to MichaelL@frogware.com for reporting the problem) 2004-11-14 * fixed yet another free memory read (many thanks for Zoran for help with purify) 2004-11-13 * fixed entries for aolserver in configure.in (many thanks for Zoran reporting this problem) * fixed --enable symbols (many thanks for Zoran reporting this problem) * fixed free memory read in namespace deletes 2004-10-30 * added error message when someone tries to delete a non-existing proc/instproc * using less memory for objects and classes with procs/instprocs, when they do not use assertions (saving 14%) * prettified langref with css * documented deletions of object procs and instproc through proc/instproc with empty args and empty body 2004-10-13 * make namespace handling code more orthogonal * using resolver for exists method (might be used in future for other methods as well) * cleanup of dead code 2004-10-09 * fixed recreation bug in connection with namespace eval * fixed exists for objects with own namespaces 2004-09-20 * 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 * 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 * 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 * 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 , Uwe Zdun * release of distribution XOTcl 1.3.1 2004-08-26 * 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 * 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 * 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 * 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 , Uwe Zdun * release of distribution XOTcl 1.3.0 2004-08-17 * fixing make for rpm * tweaking configures stuff to work with rpm 2004-08-16 * adding two sections to tutorial, updated langref.xotcl 2004-08-15 * Adding non positional arguments to serializer 2004-08-12 * 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 * 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 * 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 * 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 * 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 * yet another fixed access to freed memory (thanks to Zoran for his help with Purify ) 2004-07-26 * 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 * implemented experimental next method for delegating same-named procs to different objects 2004-07-20 * fixed a potential crash when a instmixin was registered on itself 2004-07-19 Uwe Zdun * 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 * 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=" 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 * 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 * integrated support for non-positional arguments for procs and instprocs 2004-07-02 * 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 2004-07-01 * 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 before * xotcl.c: new info option for Object and Class: info 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 * changed name of delegator methods to forward/instforward * removed most of the switches of the forwarder. We have now obj forward ?options? ?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 * fixed coredump for delegation to object without method specified (many thanks for Bryan Schofield for the bug report) 2004-06-20 * removed inclusion of * 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 INSERTTOKENS arg2 arg3... Class instcmd \ ?-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 * 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 * 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 * fixed path for installing files in Makefile.in (many thanks to Jeffrey Hobbs) * fixed path searching in xotcl.m4 2004-05-07 * 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 * 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 * 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 * 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 * 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 * fixed a potential crash in procSearch method (Thanks to Artur Trzewik for the good error report) 2004-02-29 * callMethod* calls DoDispatch instead of ObjDispatch * adding a callStackPush() for XOTclOEvalMethod() such that 'o eval self' returns '::o' 2004-02-21 * added link to XOTcl wiki to xotcl homepage. 2004-02-20 , Uwe Zdun * release of distribution XOTcl 1.2.0 2004-02-17 Uwe Zdun * fixed a Tcl_Obj ref count free that was called too early. * fixed support for Visual CC debugger * fixed Win version info 2004-02-16 * fixed a reference to a structure of a destroyed object 2004-02-16 Uwe Zdun * 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 * 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 * 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 * 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 * 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 * performed coverage analysis of regression test * changed unsuccessful branches into asserts * extended testx.xotcl for better coverage 2004-01-28 * Streamlined code; removed mixinChainOn from mixinStack and filterChainOn from filterStack and use callstack frameTypes instead. * some performance improvements 2004-01-27 * 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 * 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 * defined upvar method (uses [self callinglevel] when no level specified) * simplified stringIncrement method and added a couple of assert(). 2004-01-15 * allow volatile to be called from toplevel * decrementing refcount of global objects as needed (some had a high increment) 2004-01-14 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * Changed all variables of type "Command *" to "Tcl_Command" and defined macros Tcl_Command_XXXX to access component XXXX * new predefined method self: [ 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 " next" can be used to invoke next on the last recent invocation of a method on . 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 * 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 * update of various library functions (such as Httpd) to use sub-objects as methods (avoids calls of [self]::objname) 2003-12-19 * xotcl.c: allow to call sub-objects as methods via "my" 2003-12-16 * 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 , Uwe Zdun * release of distribution XOTcl 1.1.1 2003-12-13 * 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 * 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 * 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 * 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 * 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 * added "--with-tkinclude" * fixed "--with-tclinclude" to set TCL_INCLUDES (for all subdirs) 2003-11-29 , Uwe Zdun * release of distribution XOTcl 1.1.0 2003-11-29 * 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 * fixed include path for actiweb components (sdbm and expat) * extended transparent mixins for upvar, uplevel * extended regression test 2003-11-27 Uwe Zdun * 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 * removed ::xotcl::lib from predefined variables and from man page * added namespace require to xotclsh * added transparent mixins for instvar 2003-11-25 * 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 * xotcl.c: generalized cutting of call stack entries to skip either filters or mixins * "Class new -volatile" works now through mixins for create * added test to regression test (testx) * xotcl.c: some cleanup and speedup * updated aol-xotcl.tcl (for loading xotcl into aolserver 4.0) 2003-11-20 Uwe Zdun * 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 * 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 * 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 * removed namespace import/forget in predefined.xotcl * Makefile cleanup (fixed duplicate dependencies, quoting in loops) * added tests for xoRDF and Persistence, when actiweb is enabled * building expat, when actiweb is enabled * removed needless files from xotcl-distribution. 2003-11-09 * xotcl.c: fixed calling exit-handler twice for threads 2003-11-06 * 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 * 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 * Substituted config/config.sub and config/config.guess (many thanks to Zoran) * unix/Makefile.in fixed target install-aol 2003-10-23 * 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 * 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 * Integrated bug fixes provided by Klaus Kolowratnik for the secure http server. 2003-08-27 Uwe Zdun * 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 * 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 * doc for precedence order and transitive instmixins in tutorial 2003-08-25 * 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 * Added support for transitive instmixins in xotcl.c, added test for transitive instmixins * Various fixes for new build stuff on Windows 2003-08-20 * 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 * Fixed potential crash with shared objects in configure * First version of object tree creation via parameter 2003-07-11 * extended parameter handling code to support the creation of parameter objects * fixed a few documentation bugs 2003-07-05 * 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 * added --with-xotclsh and --with-xowish to create shell optionally 2003-05-28 Uwe Zdun * 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 * 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 * 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 * 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 * added new methods 'instmixinguard' and 'mixinguard' 2003-05-09 Uwe Zdun * 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 * xotcl.c: Changed mixinlist creation from quadratic to linear (both, in XOTclAddClass and CmdListAdd) 2003-04-29 * 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 * fixed various typos in examples in tutorial * first implementation of guarded mixins 2003-04-24 Uwe Zdun * 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 * 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 * Unified ListObjChildren and ListClassChildren into one method ListListChildren 2003-04-16 * xotcl.c: fixed segfault from classchildren (many thanks to Michael Cleverly for pointing this out) 2003-04-16 * 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 , Uwe Zdun * release of full distribution XOTcl 1.0.2 2003-03-19 , Uwe Zdun * release of full distribution XOTcl 1.0.2 2003-03-19 Uwe Zdun * 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 , Zoran Vasiljevic * some more code cleanup (do not abort when my is called outside the scope of an object) * Makefile less verbose 2003-03-07 * Made output of the serializer more compact (omitting unnecessary references to ::xotcl::Object 2003-03-07 Uwe Zdun * 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 , Zoran Vasiljevic * 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 * xotcl.c: abort, when a non-threaded xotcl version is loaded into a threaded environment (e.g. aol-server) 2003-02-28 * xotcl.c: fixed a bug the lead to a crash in "self x" 2003-02-20 * fixes to compile xotcl as a module for aolserver-4 2003-02-06 * made -volatile a method rather than an option of the new method 2003-01-18 * 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 * 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 * 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 * 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 * 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 * 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 * removed deprecated methods "parameters", "applymethods", "newChild", "newChildOf" 2002-12-23 * release of full distribution XoTcl 1.0.1 2002-12-22 * xotcl.c: some cleanup * aol-server: improved namespace.tcl (using Serializer) 2002-12-19 * 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 For details, see doc. 2002-12-18 * 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 * installWin.tcl: correction for patchlevel * changed version to 1.0.1 2002-12-14 * 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 * 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 * fixes in documentation * automatic generation of pdf files and make target for the tutorial and the language reference 2002-11-19 * fixes for configure for aolserver 3.5.* 2002-11-13 Uwe Zdun * correct check for XOTcl lib on auto_path in predefined.xotcl; it was checked for xotcl$VERSION, should be xotcl$VERSION 2002-11-08 2002-11-08 Uwe Zdun * Win makefile.vc: let nmake install call the install script * removed "class" hook from recreate ... * updateding AOL-server patch and README * finshing rpm and bin-tar generation * release of full distribution XoTcl 1.0 2002-11-06 Uwe Zdun * let the Unix Makefile also (try to) cleanup Win->Release dirs 2002-10-30 Uwe Zdun * fixes for tcl 8.0.5 2002-10-28 Uwe Zdun * 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 * xotcl.c: fixed problem with external symbol for cmdType and reactivated KEEP_TCL_CMD_TYPE for all tcl versions 2002-10-25 Zoran Vasiljevic * xotcl.c: fixed memory leak for new method. 2002-10-23 Uwe Zdun * 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 * used Tcl's Assoc structures for runtime state 2002-10-21 Uwe Zdun * corrected "abstract" next handling in predefined.xotcl 2002-09-19 * 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 * Trace.xotcl: fixed typos in documentation code, changes for "my". 2002-08-29 Uwe Zdun * 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 * disabled KEEP_TCL_CMD_TYPE for 8.4, as it did not compile for 8.4b1 2002-08-04 * Httpd.xotcl: order directories before files in directory listings 2002-07-18 * Httpd.xotcl: fix for handling broken links 2002-07-12 Uwe Zdun * Win fixes for compilation with Tcl 8.4b1 * fixed mem leak of filter search 2002-07-10 * fixes for compilation with Tcl 8.4b1 2002-07-06 * Fixed a compilation bug concerning Tcl 8.2 and younger 2002-05-30 * xotcl.c: fixed destroy bug, when object was destroyed during init * xotcl.c: minor cleanup 2002-05-16 Uwe Zdun * 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 * 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 * fixed UTF-8 conversion for filenames 2002-04-30 * Httpd.xotcl: minor cleanup (removed superfluous instvars) * xotcl.c: removed incr/decr refcount on cl-names in DoDispatch 2002-04-21 * 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 * fixed a bug in filter code (recursion blocking) 2002-04-20 * Http client code: fixed several small bugs: - url composition - error handling - redirects to different ports 2002-04-09 Uwe Zdun 2002-04-09 * finshing rpm and bin-tar generation * patch release of full distribution (0.9.4) 2002-04-08 * 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 * fixed .add files for Windows 2002-04-07 * 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 * 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 * fixed a bug with duplicated tcl_objs of XOTclObjectType that could cause double frees. 2002-04-02 * 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 * 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 * more code for volatile objects moved to C 2002-03-26 * Fixed a few more places, where recounted xotcl-objects can cause troubles (mem-leaks + invalid pointers) 2002-03-24 * auto-deletion of global vars and proc to get rid of references to xotcl-objects for deletion 2002-03-20 Uwe Zdun * 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 * xotcl.c: fixed XOTclReplaceCommand for AOL-Server (multi threading bug) 2002-03-11 * Httpd.xotcl: fixed relative pathname-bug for basic authentification 2002-03-02 * marked newChild as deprecated (use new -childof) 2002-03-02 * Changed name of selfdispatch to "my" 2002-03-01 * Httpd.xotcl: allow encoded characters in path and resource names * Httpd.xotcl: use dictionary oder for directory listings * Mime.xotcl: added some more default mime times 2002-02-24 * Httpd.xotcl: added functionality to provide directory listings * Httpd.xotcl: create specified root directory if it does not exist 2002-02-13 * Makefile.in: fixed a bug in make install ("package require package" did not work) 2002-02-12 * 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 * removed duplicated system library in library/system. The correct one is in xotcl-XXX/library!! 2002-01-09 * fixed path determination code during startup to avoid "cant read 'pf'" messages 2002-01-08 Uwe Zdun * 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 * 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 * new xotcl byte codes for XOTcl primitives next, self, 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 * fixed changeXOTclVersion, made more generic * fixed Agent migration, made all migrations synchronous (for the time being) 2001-12-17 Uwe Zdun 2001-12-17 * finshing rpm and bin-tar generation * patch release of full distribution (0.9.3) 2001-12-10 Uwe Zdun * removed two "! test" so that configures work with sh on Solaris * added make bin-tar target * removed all compiler warnings on windows 2001-12-09 * revived configure-code for aolserver, added patchlevel to log message, updated aolserver README file * renamed directory "script-creation" to "serialize" * deactivated create of unneeded installed dirs (xotclexpat, xotclgdbm, xotclsdbm) 2001-12-07 Uwe Zdun * documented recent changes in XOTcl for release 2001-12-05 * fixed call to unknown in copy method 2001-12-01 Uwe Zdun * xotcl.c: xotcl::interp rewritten 2001-11/12 Uwe Zdun * changed xotcl support a (more or less) TEA compliant build process, use Tcl stub lib, and make shells only shallow wrappers that load the XOTcl package on demand 2001-10-23 * removed code for calling variable command 2001-10-22 * xotcl.c: fixed bug for empty superclass list * fixed stub-install under 8.0.5 2001-10-20 2001-10-20 Uwe Zdun * patch release of source distribution (0.9.1) 2001-10-20 * reimplemented method 'new' of Class in C * various cleanups for stub handling * added regression test for stub library 2001-10-18 Uwe Zdun * removed linking glitch in 0.9: stub enabled lib was linked with non-stub enabled obj-files. * added a stub enabled lib to Windows make procedure * renamed stub enabled lib to (lib)xotcl-tclstubs.(so|dll) 2001-10-17 Uwe Zdun * removed "can't instvar to link" problem during aliasing to a link var 2001-10-15 2001-05-15 Uwe Zdun * XOTcl 0.9 Release 2001-10-14 * 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 * improved make clean * fixed incompatibilities in various scripts distributed with xotcl 2001-10-11 Uwe Zdun * 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 * fixed autoname method for Tcl 8.0.5 2001-10-10 Uwe Zdun * 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 Jörg Rudnik for the hint) 2001-10-08 * 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 * 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: proc|instproc 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 * minor fixes to get WIN version to run again 2001-10-03 Uwe Zdun * 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 * 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 * 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 * 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 " proc/instproc " for mixins just a class list 2001-09-26 * cleanup, removed a few bugs * new instproc for Class: insttclcmd 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 * merge with * 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 * 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 * 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 * xotcl.c: removed object reference code ... I guess we won't do references this way 2001-09-17 Uwe Zdun * 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 * 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 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 * 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 * 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 * xotcl.c: - eliminated some flaws in filterguards - forbid "new" filtering during checking a filterguard 2001-09-06 Uwe Zdun * xotcl.c: - also allowed instfilters on a mixin class of an object 2001-09-03 Uwe Zdun * 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 * various cleanup and fixes due to new features 2001-09-03 Uwe Zdun * testx.xotcl: - filterguard tests * xotcl.c: - bug corrected: filter order invalidation upon new proc/instproc ... for filter inheritance 2001-08-25 Uwe Zdun * xotcl.c: - new filter guards language construct for constraining filter appliance - introduced generic Tcl_obj* list instead of XOTclAssertion*, 2001-08-24 Uwe Zdun * 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 * 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 * 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 * xotcl.c and all tests: moved xotcl classes from ::XOTclClasses to ::xotcl::classes 2001-08-20 Uwe Zdun * 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 2001-08-17 Uwe Zdun * xotcl.c: integrated complete rewrite of filter code with per-object filters 2001-08-13 * patch release of source distribution (0.85.3) * following naming conventions of Tcl for minor changes 2001-08-11 * xotcl.c. predefined.xotcl: fast parameter inst-commands * xotcl.c: new instcommand for Object: parameteradd (to register the instcommand for parameters) * xotcl.c: applymethods renamed to configure * xotcl.c: small speedup for assertion checking * xotcl.c: simplified set methods 2001-08-09 * fixes for actiweb (agent migration was broken) * comm/Access.xotcl: a response to an HTTP-PUTS request should not contain a body.

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. 2000-12-15 * packages/make.xotcl: passing target to avoid grep through Makefile 2000-12-15 * packages/make.xotcl: less verbose * new environment variable XOTCL, points to directory where the XOTcl library lives 2000-12-13 * packages...Httpd.xotcl: close connection after errors * packages...Httpd.xotcl: elementary support for HTTP method OPTIONS 2000-12-04 * xoXML: fix info vars instvar method creates variable that is not accessible and should not be listed in info vars 2000-12-04 * version changed to 0.84 * xoXML: fix for multiple PCDATA calls after one element ----------------------------------------------------------------------------- 2000-11-30 2000-11-30 Uwe Zdun * release of Version 0.83 2000-11-30 Uwe Zdun * xoXML/xoRDF: added the ability to process mixed content PCDATA (i.e. more than one pcdata in one element) 2000-11-29 Uwe Zdun * src/lib/soccerClub.xotcl: simple introductory example for the tutorial * xotcl.c: corrected assertion checking: built in commands that affect assertions are not checked (check, info, proc, instproc, invar, and instinvar).
