# Coughvid

Simple web application for the collection of sound records of cough from patients with Covid-19.

This website has been created with hugo+syna. The source project for the static part of the web is the syna-epfl folder. Once compiled, this is the "public" folder, that has been updated in the following way:

-  Add the `cgi-bin` folder for the ubuntu script.
-  Add the `js` folder and the app, jquery and progressbar sources.
- Add the server SSL keys: `key.pem` and `cert.pem`
- Modify `index.html` to assign an id to the Record button, add the `#progressBar` and `#thanks` components, and the corresponding minor CSS tweaks. Also, include the required js files.

### Deployment instructions on coughvid.epfl.ch

- All files and folders in the repository have to be copied to `/var/www/html/` (except `.git`, of course).
- The `upload.py` cgi script has to be copied to `/var/www/cgi-bin/`, with execution permissions.
- Update `upload.py` to set `DB_PATH = '/data/coughvid_records'`, and remove `cgitb`.
- The problems we found with SELinux so far were:
  - Permission for running CGI scripts. Make sure that there is the appropriate rule in SELinux for the `/var/www/cgi-bin/` folder, with the command: `$ semanage fcontext --list | grep cgi-bin`
    - `/var/www/cgi-bin(/.*)? all files system_u:object_r:httpd_sys_script_exec_t:s0`
  - If still not working, `$ restorecon -Rv /var/www/**cgi**-bin/`.
  - Add a rule in SELinux to give write permissions in the database folder:
    - `$ semanage fcontext -a -t httpd_sys_rw_content_t "/data/coughvid_records(/.*)?"`
    - `$ restorecon -Rv /data/coughvid_records/`
