The MGraphs returned by the TcManager are lockable. A LockableMGraph has a getLock()-Method returning a ReadWriteLock. Write-Locks can be used if the applications logic requires it, i.e. when it wants to ensure that the MGraph isn't modified by another thread while some triples are being added or removed bading on the presence or absence of other triples (note that its a violation of the open world assumption if the absence of some triples causes some actions to be done). +
+ +
Readlocks must be used when multiple threads access an MGraph and a method returning an Iterator is used. In this case a read-lock must be obtained before calling the method on MGraph and released only after the last usage of the returned iterator. Failing to do so may result in ConcurrentModification when another threads modifies the MGraph while we are iterating over it. +
+ +
Currently (this might change infuture versions), it is also necessary to lock on the MGraphs against which a sparql select queries is directed. The lock on the MGraphs should be kept till iteration over the resultset is compleeted. +
+ +

How do I create deadlock-safe locks? +

+
There is no such thing, if you try to get a write-lock withing a read-locked section you'll have a deadlock. +
+
+ +

What is the best way to Lock a Graph in a service? (the developers, wich use the service know nothing about the lock and set own locks - so the service needs to check something) +

+
The service documentation should be clear about which MGarphs the service might be writing to, so the caller can make sure it holds no read-lock on one of these MGraph. +
+
