reader.stop() Timeout issue about python-mercuryapi

[gotthardp]

The error appears to be thrown at (re)instantiation of the reader, not at reader.stop(). Could it be a bug in your code?

Hey,
yeah you're right. It does not happen on reader.stop_reading(). The Timeout exception is thrown at
reader = mercury.Reader(XYZ) if a read process is ongoing.
Do you have a clever on how to stop a ongoing reading process?

[gotthardp]

the read() function has a timeout. it cannot be interrupted

For everyone that has similar issues, here is what the problem ist/how to solve it:
It is not possible to define reader = mercury.Reader("tmr:///dev/ttyUSB0") if a read is ongoing. The channel is being used and therefore blocks the new connection.
The read has to be stopped correctly before reconnection with reader.stop_reading().
However sometimes it takes some time until the read is stopped. In my case, the read function is a very complex one. So i wrapped my entire read process inside a thread and gave it an attribute. If this attribute is set to False, the read will be stopped with reader.stop_reading() and just to be sure it is really stopped, the entire Thread is stopped. But this is a custom solution I guess.
