Re: [gephi-dev] [Dynamics] Unable to get a graph snapshot after a read lock

[Mathieu Bastian]

Locking is done on the whole model, not on the graph so when you copy it enters a writeLock(). Remove your readLock and it should be fine.

Hi @dev,

The following code rises a readLock exception:

graph.readLock();
Graph g = dynamicGraph.getSnapshotGraph(low, high);

...

graph.readUnlock();

This is a wrong behavior, as getSnapshotGraph() is intended to return a copy of the working graph.

The issue is at DynamicGraphImpl.java line 246:

Graph vgraph = model.getGraph(currentView);

This copy, in which nodes outside the interval are removed, should be free of locks.


Cheers,
Seb
