#
# Streamtuner2 is a GUI browser for internet radio directories. Various
# providers can be added, and streaming stations are usually grouped into
# music genres or categories. It starts external audio players for stream
# playing and streamripper for recording broadcasts.
#
# It's an independent rewrite of streamtuner1 in a scripting language. So
# it can be more easily extended and fixed. The use of PyQuery for HTML
# parsing makes this simpler and more robust.
#
# Stream lists are stored in JSON cache files.
#
#
#
""" project status """
#
# The application runs mostly stable. The GUI interfaces are workable.
# It's supposed to run on Gtk2 and Gtk3. Python3 support is still WIP.
# There haven't been any optimizations regarding memory usage and
# performance. The current internal API is vastly undocumented.
#
# current bugs:
# - audio- and list-format support is not very robust / needs better API
# - not all keyboard shortcuts work
#
# features:
# - treeview lists are created from datamap[] structure and stream{} dicts
# - channel categories are built-in defaults (can be freshened up however)
# - config vars and cache data get stored as JSON in ~/.config/streamtuner2/
#
# missing:
# - localization
#
# security notes:
# - directory scrapers use fragile regular expressions - which is probably
# not a security risk, but might lead to faulty data
# - MEDIUM: little integrity checking for .pls / .m3u references and files
# - minimal XML/SGML entity decoding (-> faulty data)
# - MEDIUM: if system json module is not available, pseudo-json uses eval()
# to read the config data -> limited risk, since it's only local files
# - HIGH RISK: no verification of downloaded favicon image files (ico/png),
# as they are passed to gtk.gdk.Pixbuf (OTOH data pre-filtered by Google)
# - MEDIUM: audio players / decoders are easily affected by buffer overflows
# from corrupt mp3/stream data, and streamtuner2 executes them
# - but since that's the purpose -> no workaround
