If anything wrong happens after a transaction is locked and before the end of onTransactionCommitted, recovery phase should be run again, so that the master gets correct last tid.

This implementation proper cache invalidation. Connection to master is also made optional to load from storage nodes, as long as partition table contains up-to-date data (which is anyway unlikely to change when there is no master).

This is enough because on disconnection, the master already aborts all transactions on its side.

This may help client to recover after an assertion failure. For example, this should fix the following bug: ERROR ZODB.Connection Couldn't load state for 0x13b6 Traceback (most recent call last): File "ZODB/Connection.py", line 851, in setstate self._setstate(obj) File "ZODB/Connection.py", line 901, in _setstate p, serial = self._storage.load(obj._p_oid, '') File "neo/client/Storage.py", line 85, in load return self.app.load(oid)[:2] File "neo/client/app.py", line 435, in load result = self._loadFromStorage(oid, tid, before_tid) File "neo/client/app.py", line 450, in _loadFromStorage for node, conn in self.cp.iterateForObject(oid, readable=True): File "neo/client/pool.py", line 130, in iterateForObject conn = getConnForNode(node) File "neo/client/pool.py", line 155, in getConnForNode conn = self._initNodeConnection(node) File "neo/client/pool.py", line 61, in _initNodeConnection connector=app.connector_handler(), dispatcher=app.dispatcher) File "neo/lib/connection.py", line 749, in __init__ super(MTClientConnection, self).__init__(*args, **kwargs) File "neo/lib/connection.py", line 685, in __init__ node.setConnection(self) File "neo/lib/node.py", line 119, in setConnection attributeTracker.whoSet(self, '_connection') AssertionError

Also, saves one local variable assignment in "hit" code path.

Use a non-intrusive code profiling tool with NEO instead, like pprofile.

Also, drop extraneous parentheses in another set's creation.

Nodes are likely to be running, so filtering before sort is unlikely to save time. Caller is likely to stop iterating after first yield connection ("load" case), so move filtering inside loop. Also, document non-straightforward code.

Connection is more often established than not, so do a first lookup without locking, and only acquire it if it misses. Then do a second lookup in case another thread also established connection, and connect if it still misses.

We think there's still a bug, in ZODB.Connection or ZPublisher/Publish, but since commit c277ed20, NEO does not require anymore that Storage.sync() is called in order to take into account invalidations that have already been received since the last tpc_finish. IOW, this is not the place for such fix because it's independant to NEO. ERP5 already ships it for ZEO (patch disabled by default).

loadBefore is more likely than other loads, as it is how repeatable-read is implemented and the vast majority of accesses are scoped to a transaction. So put it first in 3-branches "if" choosing between load/loadBefore/loadSerial code paths. next_serial is likely to not be found, because application will likely operate on up-to-date objects. So a test is more efficient than a try..except. Inline this test in return statement to avoid defining a local.

Next version is actually a metapackage depending on: persistent 4.0 BTrees 4.0 ZODB 4.0 ZEO 4.0 Note that version '123dev' is considered lower than '123'
