Hi, folks. I'm wondering if it's possible to catch python exceptions in
the pcaspy Driver class. For instance, I have a very simple dummy
server (attached), in whose write() method there is a call that should
throw a NameError. However, when the server is running, a CA write
(e.g. "caput MTEST:RAND 3") produces the following output:
filename="../../../../src/cas/generic/st/casStreamOS.cc" line number=479
Internal failure - unexpected problem with client's input - forcing disconnect
The server process also continues to run.
Is there a way to get a proper python exception out of this situation?
I would prefer the server to terminate with the exception, but I would
be ok with the server continuing to run if the exception in the Driver
could at least be reported to stderr or the like. As is it's a little
tricky to debug these errors.
Thanks in advance for any help.
jamie.
#!/usr/bin/env python
From pcaspy import Driver, SimpleServer
prefix = 'MTEST:'
pvdb = {
'RAND' : {
'prec' : 3,
},
}
class myDriver(Driver):
def __init__(self):
super(myDriver, self).__init__()
def write(self, channel, value):
foo
if __name__ == '__main__':
server = SimpleServer()
server.createPV(prefix, pvdb)
driver = myDriver()
while True:
server.process(0.1)
