I have just released ZEO 1.0 beta 6. It's been almost six months since the last beta release, so it was surely time. This release fixes two bugs that Zope Corp. has recently run into in the field. See http://www.zope.org/Products/ZEO/. Here are the changes: - Fixed a bug that could cause the server to stop committing transactions for a storage. The bug occurred under the following circumstances: - A synchronous client made a tpc_begin() request. - The request arrived while another transaction was in progress. - The other transaction finished. - The client closed the connection or an unexpected error occurred while the server was handling the client's tpc_begin(). The fix is to make the code to resume a waiting transaction robust in the face of disconnects and errors. - Fixed bugs in the storage server and the trigger module that caused the server to fail with uncaught exceptions when it received a signal. The start script installs several signal handlers, so the server should not fail when those signals are received. These bugs might have occurred in other circumstances, too. Note: The signal handlers are not particularly useful with the default zLOG backend (STUPID_LOG_FILE). - Upgrade to license to ZPL 2.0 I expect to release ZEO 1.0 final next week. I'll also take this opportunity to mention future ZEO development plans. I plan to make a ZEO 1.1 release sometime this month. This release will add some debugging support and a few minor features that have proved useful in high-volume ZEO clusters. I also plan to make an alpha release of ZEO 2.0. ZEO 2 is a partial re-implementation of ZEO that provides a new RPC protocol between the ZEO clients and server. The new RPC protocol will make it possible to extend ZEO with new features and to make changes that will improve performance. ZEO 2.0 alpha 1 will be a baseline that provides the new protocol, but probably none of the features. If there are any crucial feature requests for ZEO 1.1, now is the time to make them (patches preferred :-). Otherwise, new features will be postponed to ZEO 2.0. Jeremy
