1.10 (2018-07-16)
-----------------
A important performance improvement is that the replication now remembers where
it was interrupted: a storage node that gets disconnected for a short time now
gets fully operational quite instantaneously because it only has to replicate
the new data. Before, the time to recover depended on the size of the DB, just
to verify that most of the data are already transferred.
As a small optimization, an empty transaction extension is now serialized with
an empty string.
The above 2 changes required a bump of the protocol version, as well as an
upgrade of the storage format. Once upgraded (this is done automatically as
usual), databases can't be opened anymore by older versions of NEO.
Other general changes:
- Add support for custom compression levels.
- Maximize resiliency by taking into account the topology of storage nodes.
- Fix a few issues with ZODB5. Note however that merging several DB with the
Importer backend only works if they were only used with ZODB < 5.
Master:
- Automatically discard feeding cells that get out-of-date.
Client:
- Fix partial import from a source storage.
- Store uncompressed if compressed size is equal.
Storage:
- Fixed v1.9 code that sped up the replication by sending bigger network
packets.
- Fix replication of creation undone.
- Stop logging 'Abort TXN' for txn that have been locked.
- Clarify log about data deletion of discarded cells.
MySQL backend:
- Fix replication of big OIDs (> 16M).
- Do not full-scan for duplicates of big OIDs if deduplication is disabled.
- Fix remaining places where a server disconnection was not catched.
SQlite backend:
- Fix indexes of upgraded databases.
Importer backend:
- Fetch and process the data to import in a separate process. It is even
usually free to use the best compression level.
- New option to write back new transactions to the source database.
See 'importer.conf' for more information.
- Give a title to the 'import' and 'writeback' subprocesses,
if the 'setproctitle' egg is installed.
- Log when the transaction index for FileStorage DB is built.
- Open imported database in read-only whenever possible.
- Do not trigger speedupFileStorageTxnLookup uselessly.
- Do not checksum data twice.
- Fix NameError when recovering during tpc_finish.
