`ReleaseQHYCCDResource` does not stop CamManagerThread #15

Closed tail-feather closed 4 years ago

tail-feather commented 4 years ago

I'm having trouble with the QHYCCD driver (indigo_ccd_qhy2) crashing on INDIGO. This seems to be happening on the QHYCCD SDK side.

Calling ReleaseQHYCCDResource and waiting for about 5 seconds, I noticed that the log of CamManagerThread was still being output.

Since INDIGO runs the driver in an independent process, it kills the process when it unload the driver. If the thread hasn't been JOINed by the time the process ends, an exception should be raised.

P.S. If SetQHYCCDAutoDetectCamera(false); is set before calling InitQHYCCDResource, the INDIGO will not crash.

Oops, I noticed that SetQHYCCDAutoDetectCamera doesn't exist in the SDK here. I'm sorry if I'm in the wrong place.
