1.11 (2019-03-11)
-----------------
This release continues the work in v1.8 to stabilize NEO. A new 'stress'
tool was added: it kills storage nodes and resets TCP connections randomly,
while causing high concurrency activity. It revealed many bugs of all kinds,
including crashes and corruptions. Most of them happened after network
disconnection. In order to fix them all, several improvements have also been
done to logging:
- New neoctl command to flush the logs of all nodes in the cluster.
- In logs, dump the partition table in a more compact and readable way.
- client: log_flush most exceptions raised from Application to ZODB
- More RTMIN+2 (log) information for clients and connections.
- New log format to show node id (and optionally cluster name) in node column.
- neolog: add support for zstd-compressed logs.
- neolog: do not die when a table is corrupted.
Other changes:
- sqlite: optimize storage of metadata (the speed up in v1.9 about indexing
'obj' primarily by 'oid' was only effective for MySQL).
- Fix error handling when setting up a listening connector.
- The command line parsing of all executables has been completely rewritten,
fixing a few minor bugs.
