The Null Pointer
================

This is a no-bullshit file hosting and URL shortening service that also runs
`0x0.envs.net <https://0x0.envs.net>`_. Use with uWSGI.

If you are running nginx, you should use the ``X-Accel-Redirect`` header.
To make it work, include this in your nginx config’s ``server`` block::

    location /up {
        internal;
    }

where ``/up`` is whatever you’ve configured as ``FHOST_STORAGE_PATH``
in ``fhost.py``.

For all other servers, set ``FHOST_USE_X_ACCEL_REDIRECT`` to ``False`` and
``USE_X_SENDFILE`` to ``True``, assuming your server supports this.
Otherwise, Flask will serve the file with chunked encoding, which sucks and
should be avoided at all costs.

To make files expire, simply create a cronjob that runs ``cleanup.py`` every
now and then.

Before running the service for the first time, run ``./fhost.py db upgrade``.


NSFW Detection
--------------

0x0 supports classification of NSFW content via Yahoo’s open_nsfw Caffe
neural network model. This works for images and video files and requires
the following:

* Caffe Python module (built for Python 3)
* ``ffmpegthumbnailer`` executable in ``$PATH``


INSTALL
-------
::

    apt update
    apt install python3-pip nginx uwsgi uwsgi-plugin-python3 certbot
    git clone https://github.com/cremesk/0x0.git /srv/0x0

    cd /srv/0x0
    pip3 install --user `cat requirements.txt`
    ./fhost.py db upgrade


FAQ
---

Q:
    What about file management? Will I be able to register an account at some
    point?
A:
    No.

Q:
    Why are you storing IP addresses with each uploaded file?
A:
    This is done to make dealing with legal claims and accidental uploads
    easier, e.g. when a user requests removal of all text files uploaded from
    a certain address within a given time frame (it happens).
