Contrary to FileStorage, NEO remembers uses of readCurrent().

With the switch to msgpack, there was no schema anymore whereas it was sometimes used for both automatic conversion (e.g. the last argument of AskStoreTransaction must now be explicitly cast to list) and type checking. This somewhat reintroduces a kind of schema that: - is used by the test suite for type checking - can be generated automatically from the test suite when one change the procotol

Not only for performance reasons (at least 3% faster) but also because of several ugly things in the way packets were defined: - packet field names, which are only documentary; for roots fields, they even just duplicate the packet names - a lot of repetitions for packet names, and even confusion between the name of the packet definition and the name of the actual notify/request packet - the need to implement field types for anything, like PByte to support new compression formats, since PBoolean is not enough neo/lib/protocol.py is now much smaller.

The following 2 operations can be onerous and they should not be directly usable without some kind of confirmation by the user: - Dropping a node now requires to first stop it. - Tweaking does not exclude anymore automatically DOWN nodes, because a node could go DOWN between the moment the user sends the command to tweak and the actual tweak by the master.

Initially, I wanted to do the simulation inside neoctl but it has no knowledge of the topology (the master don't send devpath values of storage nodes). Therefore, the work is delegated to the master node, which implies a change of the protocol.

This stops abusing ProtocolError, which disconnects the admin node needlessly. The many 'if ... raise RuntimeError' in neo/neoctl/neoctl.py could be turned into assertions.

neoctl gets a new command to change the number of replicas. The number of replicas becomes a new partition table attribute and like the PT id, it is stored in the config table. On the other side, the configuration value for the number of partitions is dropped, since it can be computed from the partition table, which is always stored in full. The -p/-r master options now only apply at database creation. Some implementation notes: - The protocol is slightly optimized in that the master now sends automatically the whole partition tables to the admin & client nodes upon connection, like for storage nodes. This makes the protocol more consistent, and the master is the only remaining node requesting partition tables, during recovery. - Some parts become tricky because app.pt can be None in more cases. For example, the extra condition in NodeManager.update (before app.pt.dropNode) was added for this is the reason. Or the 'loadPartitionTable' method (storage) that is not inlined because of unit tests. Overall, this commit simplifies more than it complicates. - In the master handlers, we stop hijacking the 'connectionCompleted' method for tasks to be performed (often send the full partition table) on handler switches. - The admin's 'bootstrapped' flag could have been removed earlier: race conditions can't happen since the AskNodeInformation packet was removed (commit d048a52d).

It is often faster to set up replicas by stopping a node (and any underlying database server like MariaDB) and do a raw copy of the database (e.g. with rsync). So far, it required to stop the whole cluster and use tools like 'mysql' or sqlite3' to edit: - the 'pt' table in databases, - the 'config.nid' values of the new nodes. With this new option, if you already have 1 replica, you can set up new replicas with such fast raw copy, and without interruption of service. Obviously, this implies less redundancy during the operation.

--kill-mysqld should be combined with something like -f .3 -r .1 to give storage nodes enough time to recover. And also -D 0 to focus testing on the storage backend rather than NEO.

If the source DB is lost during the import and then restored from a backup, all new transactions have to written back again on resume. It is the most common case for which the writeback hits the maximum number of transactions per partition to process at each iteration; the previous code was buggy in that it could skip transactions.
