SpyServ reentrance warning and slowdown when using SIS3316RawReader through MultiFormatReader
After connecting a socket to the SpyServer of a MultiFormatReader, a reentrance warning is given repeatedly and read slows down to a halt. Example:
# start reading in one process.
mfr = ROOT.NGMMultiFormatReader()
mfr.SetPassName("ROOT")
mfr.SetSkipWaveforms(True)
port = 9090
mfr.LaunchSpyServ(port)
filename = sys.argv[1]
mfr.OpenInputFile(filename)
mfr.StartAcquisition()# in a separate process
socket = ROOT.TSocket('localhost',9090)output looks like:
Collection name='TOrdCollection', class='TOrdCollection', size=0
Press Ctl-C to Interrupt NGMMultiFormatReader
Collection name='TOrdCollection', class='TOrdCollection', size=1
OBJ: TSignalHandler TSignalHandler Signal event handler
