From jm at nexedi.com Wed Jul 30 15:47:06 2014 From: jm at nexedi.com (Julien Muchembled) Date: Wed, 30 Jul 2014 15:47:06 +0200 Subject: [Neo-users] [ANNOUNCE] NEO 1.2 Message-ID: <53D8F75A.3080206@nexedi.com> Hi, With pleasure we announce the release of NEO 1.2, which is published on pypi as "neoppod": http://pypi.python.org/pypi/neoppod The most important changes in this version are the work about conversion of databases from/to NEO: - A new 'Importer' storage backend has been implemented and this is now the recommended way to migrate existing Zope databases. See 'importer.conf' example file for more information. - 'neomigrate' command refused to run since version 1.0 - Exported data serials by NEO iterator were wrong. There are still differences with FileStorage: - NEO always resolves to original serial, to avoid any indirection (which slightly speeds up undo at the expense of a more complex pack code) - NEO does not make any difference between object deletion and creation undone (data serial always null in storage) Apart from that, conversion of database back from NEO should be fixed. Other changes: - A warning was added in 'neo.conf' about a possible misuse of replicas. - Compatibility with Python 2.6 has been dropped. - Support for recent version of SQlite has been added. - A memory leak has been fixed in replication. - MySQL backend now fails instead of silently reconnecting if there is any pending change, which could cause data loss. - Optimization and minor bugfixes. And we forgot to announce NEO 1.1 which was a smaller release: - Client failed at reconnecting properly to master. It could kill the master (during tpc_finish!) or end up with invalid caches (i.e. possible data corruption). Now, connection to master is even optional between transaction.begin() and tpc_begin, as long as partition table contains up-to-date data. - Compatibility with ZODB 3.9 has been dropped. Only 3.10.x branch is supported. - checkCurrentSerialInTransaction was not working. - Optimization and minor bugfixes. Regards, The NEO team.
