• Documentation: server.py: be12843f29839b6f9875b71c59c386e044256170

What I Did Today..

• I modified server.py. I finally learnt what the decorator operator in Python does. I added properties for path, video_port, audio_port, control_port and record_file. This allowed me to add exception handlers. Also detection of errors and raising is possible.
• I wrote unittests test_server.py
. These cover almost all errors that may come up in server.py

Problems I Faced..

• Using properties: Very nicely explained at:

  • http://stackoverflow.com/questions/6304040/real-world-example-about-how-to-use-property-feature-in-python

Next What..

Do the same for all other files (Write properties wherever required and unittests)
