Goals

  • The scan should stop without crashing
  • A message should be shown to the user explaining that he has no disk space left

Tasks

  • Add a global free disk space check that's triggered when there is 50mb of disk space left on the partition where the HTTP cache and DB is saved. Note that I said "global", this means that it's not tied to the DBMS.
  • The check should run once every N requests
  • When it fails it should raise a IOError and end up in w3afCore.py error handling for no disk space left:
        except IOError as (error_id, error_msg):
            # https://github.com/andresriancho/w3af/issues/9653
            # IOError: [Errno 28] No space left on device
            if error_id == errno.ENOSPC:
                msg = ('The w3af scan will stop because the file system'
                       ' is running low on free space. Check the "%s" directory'
                       ' size, overall disk usage and start the scan again.')
                msg %= get_home_dir()

                print(msg)
                om.out.error(msg)
            else:
                raise
  • Verify that the fix prevents the current issue (note that it's on the GUI!)
