"""
|
|
Patch bbctrl Web.py so font files get the correct MIME type.
|
|
|
|
Background
|
|
----------
|
|
The Onefinity controller (Pi 3B running Raspbian stretch) ships Python
|
|
3.5, whose ``mimetypes`` module does not recognize ``.woff``, ``.woff2``
|
|
or ``.ttf``. Tornado's ``StaticFileHandler`` therefore falls back to
|
|
``application/octet-stream`` for those, and Chromium 72 (the Pi's
|
|
onboard kiosk browser) refuses to use such payloads as web fonts. The
|
|
result is that every FontAwesome icon renders as an empty box on the
|
|
kiosk display.
|
|
|
|
This patch monkey-patches ``StaticFileHandler.get_content_type`` to
|
|
emit the right MIME types. It is idempotent: running it twice is a
|
|
no-op. Run with ``sudo`` so it can rewrite the egg's Web.py.
