Dear XOTcl Community,
XOTcl 1.5.6 is available. This version is mostly a fix release for some problems that were apparently quite long in the code and could cause crashes for threaded applications.
best regards -gustaf neumann
Announcing XOTcl 1.5.6 *************************
We are pleased to announce the availability of XOTcl 1.5.6.
Major changes relative to 1.5.4 are:
* Fixes for treating global volatile objects (many thanks to Zoran for his concise reports). The problem was that XOTcl uses C-level var traces containing pointers to objects. If for some reason, these objects are destroyed earlier, this results in dangling references. This problem caused especially problems in the automatic cleanup of variables at the end of a thread.
* Fix for Tcl 8.4.* for situations, where Tcl variables contained references to deleted XOTcl objects. The problem was introduced by the VarReform changes between 1.5.3 and 1.5.4 by a bad side effect of a Tcl_Obj based command to look up Tcl command structurs. The problem did not exist for xotcl compiled against Tcl 8.5 and is as well fixed on the Tcl side in CVS (might become available, when one more Tcl 8.4 release is eventually released)
* Serializer: - Added dependency rule in serializer to ensure slots of super-classes are listed before subclasses. (Thanks to Stefan Sobernig for reporting the problem)
- Moved deactivation of traces into "Serializer all" to get simpler results on "o serialize".
* Extended regression tests
For more details about the changes, please consult the ChangeLog and documentation.
