cargohold lets you distribute and receive files on your own terms.
Create private links that let other people upload files to you, or send them a link
that lets them download or view the files you want them to have.
* Create a directory where cargohold will store the uploaded files
* Set the directory's owner to the user you want uwsgi to run the application under
* Edit `backend/config.py` to match your setup
* Edit `configs/nginx.config` to match your setup
* Note that the `client_max_body_size` directive will limit the maximum size of a single uploaded file
* Install `configs/nginx.config` to `/etc/nginx/sites-enabled/`
* Edit `configs/uwsgi.ini` to match your setup
* Note that the `limit-post` option will limit the maximum size of a single uploaded file
* Install `configs/uwsgi.ini` to `/etc/uwsgi/apps-enabled/`
* Create the cargohold database by running `sqlite3 cargohold.db3 < backend/cargohold.sql`
* Update `backend/config.py` with the path to your database
* If you want to use the web administration interface, select an authentication provider in `backend/config.py`. Some providers might need additional configuration. See the section on Authentication for more details.
TBD: Extend this.
The database stores the the following data for each alias
* *Alias*: The identifier to be appended to the base URL
* *User*: The user the identifier belongs to, for administrative and storage accounting purposes
* *Real path*: The on-disk directory name where, when prepended with both the `fileroot` and optionally, the `userdir`, the data is stored. Multiple aliases may point to the same real path.
* *Access level*: The access level this alias permits to the real path. A string consisting of any of the characters *c* (*C*reate / Upload), *r* (*R*etrieve / Read), *u* (*U*pdate), *d* (*D*elete) in any order.
* *Storage limit*: Per-alias storage limit (applied when uploading)
* *Display mode*: Parameter to the file-listing interface, customizing end-user layout.
The storage limit for each alias (applied when uploading files) is calculated as the minimum of the following parameters
* Global disk free space
* `global_limit` in `backend/config.py`
* The per-user limit minus the disk size currently used by the user, if the per-user limit is not `0`
* The per-alias limit minus the disk size currently used by the files in the alias, if the per-alias limit is not 0 / NULL
cargohold integrates somewhat tightly with nginx using the X-Accel-Redirect mechanism.
Other httpds may provide a similar mechanism, which will need to be called out to in the
`playout()` routine in `main.py`.
