This fix an issue where some locks were not released on a storage because the node list used to sent abort notifications was built with the content of data_dict that don't keep informations about unresolved conflicts. git-svn-id: https://svn.erp5.org/repos/neo/trunk@2176 71dcc9de-d417-0410-9af5-da40c76e7ee4

There are 2 objectives: - Prevent randomly trying to connect to an unresponsive storage node, which impairs performances a lot. Note that this happens only when the master didn't notice the disconnection, so the node is still in running state in the node manager. - Increase connection reuse, saving the cost of establishing a new connection and a slot in connection pool. Randomisation should be kept to even out storage node use. git-svn-id: https://svn.erp5.org/repos/neo/trunk@2173 71dcc9de-d417-0410-9af5-da40c76e7ee4

Deadlock occurs between connection establishment (which holds the pool lock and waits for an answer on its thread queue) and epoll thread, which tries to unregister the connection from pool (trying to take pool lock) before notifying the queue. Unregistering a connection from pool does not require taking the pool lock, as it is just meant to prevent connections from being created in parallel. git-svn-id: https://svn.erp5.org/repos/neo/trunk@2172 71dcc9de-d417-0410-9af5-da40c76e7ee4

A connection lost no more abort current transactions and clean the node index (by calling abortFor). Do this job each time a transaction aborted to avoid empty entries and memory leaks. git-svn-id: https://svn.erp5.org/repos/neo/trunk@2170 71dcc9de-d417-0410-9af5-da40c76e7ee4

Bug reported by Gaël Le Mignot: in a sample case he encountered, "description" was a unicode object, causing encoding failure in packet construction. Python "str" is used in ZODB FileStorage code (see format.py), so just do the same. git-svn-id: https://svn.erp5.org/repos/neo/trunk@2167 71dcc9de-d417-0410-9af5-da40c76e7ee4

ConnectorConnectionClosedException might get triggered when notifying a node about transaction abortion, causing tpc_abort to fail eating pending answers and clearing local_var.

When a delayed store is processed, don't take the lock if the transaction is no more registered (may have been aborted due to a timeout with the delayed store). Change the TransactionManager API: add register() that must be called before any storeObject/storeTransaction operation. git-svn-id: https://svn.erp5.org/repos/neo/trunk@2159 71dcc9de-d417-0410-9af5-da40c76e7ee4

If the last storage node gets disconnected, an operation failure will occur, so there is no risk of sending AnswerTransactionFinished to client if some object was not stored. git-svn-id: https://svn.erp5.org/repos/neo/trunk@2150 71dcc9de-d417-0410-9af5-da40c76e7ee4

onStoreTimeout is called by poll thread, which causes a new local_var to be implicitly created with a new queue (specific to poll thread, which isn't supposed to have one). To know the queue that should receive AnswerHasLock, reuse the one registered to dispatcher to receive AnswerStoreObject. git-svn-id: https://svn.erp5.org/repos/neo/trunk@2144 71dcc9de-d417-0410-9af5-da40c76e7ee4

This fixes cases where a thread is expecting some answer from queue, and a packet gets forgotten, as it would block until next expected packet arrives (if there is no next packet, it will wait forever). git-svn-id: https://svn.erp5.org/repos/neo/trunk@2142 71dcc9de-d417-0410-9af5-da40c76e7ee4
