ZODB4 alpha 2 release
by Jeremy Hylton 20 Jun '03

20 Jun '03

We've released ZODB4 alpha 2, a snapshot of current progress on ZODB4. You can get it at http://www.zope.org/Products/ZODB4. This release of ZODB4 contains all (or most) of the new features that have been added to ZODB3 since the last ZODB4 alpha release. This release contains the top-level persistence, transaction, zdaemon, and zodb packages, as well as zope.interface and zope.testing. The implementation depends on zope.interface, but only in fairly limited way. The zope.testing package is only used by a few unit tests. The zodb package includes FileStorage, two memory storages, two storages based on BerkeleyDB, and ZEO, a client-server protocol for ZODB. This will probably be the last ZODB4 release for a while, as we focus on getting Zope3 into shape. Jeremy

Hi all, Interested in what _Tim Couper_ has to say? Have a look at the fifth EuroPython2003 interview: http://www.europython.org/other/interviews/entries/tim_couper In previous note, we made the mistake by adding unintentionally a dot to the end of the url. Thanks to the several people who reported this. For those who didn't managed to read the interview because of this, here is the link without a dot: http://www.europython.org/other/interviews/entries/martijn_faassen For the EuroPython visitors: Since the first talks start at 9:00h and everybody has to pass the registration desk to pick up their badge, the doors will be open from 7.30h am, on the first day of the conference, ie 25 june 2003. Yes this early, so for the people who start the day very early, you know what you can do :-) See you within 6 days! Regards, EuroPython

EuroPython's 4th Interview
by Tom Deprez 17 Jun '03

17 Jun '03

EuroPython's fourth interview! Ever heard about the Python Secret Underground movement? No? Well, _Martijn Faassen_ neither... But, he heard about some rumours and shared them with us. Confused concerning PSU? Who would not? But, perhaps Forest (an XML Database on the workbench) might help you to see the forest through the trees. Enjoy the interview at http://www.europython.org/other/interviews/entries/martijn_faassen. Regards, www.europython.org

ZODB 3.2b2 release
by Jeremy Hylton 17 Jun '03

17 Jun '03

We have released ZODB 3.2b2 available from the usual place: http://www.zope.org/Products/ZODB3.2 This release includes several critical bug fixes for ZEO. The bugs are more likely to affect sites that see a lot of read conflicts (resolved or unresolved). The bugs can cause data loss or corruption. These are the same bug fixes that went into ZODB 3.1.2b2 last week. ZODB 3.2 has a number of new features and improvements over ZODB 3.1: - improve performance and stability of ZEO - new ZEO authentication protocol - new configuration language, ZConfig, for databases, storages, and ZEO servers - many bug fixes I have included the release notes for 3.2b2 below. Jeremy What's new in ZODB3 3.2 beta 2 ============================== Release date: 16-Jun-2003 Fixed critical race conditions in ZEO's cache consistency code that could cause invalidations to be lost or stale data to be written to the cache. These bugs can lead to data loss or data corruption. These bugs are relatively unlikely to be provoked in sites with few conflicts, but the possibility of failure existed any time an object was loaded and stored concurrently. Fixed a bug in conflict resolution that failed to ghostify an object if it was involved in a conflict. (This code may be redundant, but it has been fixed regardless.) The ZEO server was fixed so that it does not perform any I/O until all of a transactions' invalidations are queued. If it performs I/O in the middle of sending invalidations, it would be possible to overlap a load from a client with the invalidation being sent to it. The ZEO cache now handles invalidations atomically. This is the same sort of bug that is described in the 3.1.2b1 section below, but it affects the ZEO cache. Fixed several serious bugs in fsrecover that caused it to fail catastrophically in certain cases because it thought it had found a checkpoint (status "c") record when it was in the middle of the file. Two new features snuck into this beta release. The ZODB.transact module provides a helper function that converts a regular function or method into a transactional one. The ZEO client cache now supports Adaptable Persistence (APE). The cache used to expect that all OIDs were eight bytes long.
