Memory leak in eCAL Python binding

[KerstinKeller]

Problem Description

The following simple Python monitoring sample leaks memory:

import ecal.core.core as ecal_core
import sys
import time

def main():
   ecal_core.initialize(sys.argv, "Python Monitoring")
   ecal_core.mon_initialize()
   
   while ecal_core.ok():
       try:
           topics = ecal_core.mon_monitoring()[1]['topics']
           for topic in topics:
               print(topic['tname']) 
       except Exception:    
           pass
       time.sleep(1)
      
   
if __name__ == "__main__":
   main()

Problem

The problem is that mon_monitoring (and also mon_logging ) doesn't properly decrease all internal references and thus leaks memory.

How did you get eCAL?

I don't know
