Remote Debug

The RemoteDebugger class handles debugging. It might prove a slight challenge, to debug python programs executed using the shell and bash scripts. But we can look into that later. The so-far the debugger works as follows:

• we use the pydevd library for debugging
• to remote debug one must first run the python debugger from ide listening on localhost:10999 (The port is chosen at random.)
• it's important to set the correct path mapping - this is ide specific (something like /home/krystof/Projects/qgis_patrac_3=/usr/share/qgis/python/plugins/qgis_patrac)
• ai. the path on the host machine to the plugin files = the path to the plugin files in the container
• the open port 10999 on host must be accessible from the container
• a simple solution for this is to run the container with the --net=host option
• once the debugger is running, one can start the debugger by calling the method RemoteDebugger.setup_remote_pydev_debug('localhost',10999) from the patrac script
• idealy have it be the first line of the PatracPlugin classes constructor in the patrac.py file
