Installation

pip install -r requirements.txt
cp config.py.example config.py
Customize config.py
./depot or use uWSGI
Visit http://your.domain/signin

Nginx configuration

In nginx.conf, put following code under http section.

server {
	listen 80;
	server_name [domain];

	location / { try_files $uri @depot; }
	location @depot {
		include uwsgi_params;
		uwsgi_pass unix:/tmp/depot.sock;
	}
}

RECOMMENDED: If you are using XSendfile for file transfer, put following code under server section above.

The importance of XSendfile is explained in Notes section.

	location /[HTTPD_BASE_DIR in config.py]/ {
		internal;
		alias /[UPLOAD_BASE_DIR in config.py]/;
	}

Usage

Using Flask built-in web server:

./depot

Using uWSGI(highly recommended):

uwsgi -s /tmp/depot.sock --module app --callable app --chmod-socket=777

If you upload large files often, it consumes long time - depends on your server specs - for retrieving file and hashing sum of it. This means python process will stuck, nothing can be uploaded until hashing gets finished. To solve this problem, set -p option to create multiple processes.

Notes

As written in config.py.example, using flask.send_file() causes slow download speed, so set HTTPD_USE_X_SENDFILE to True if you care about download speed.

Depot was originally planned for image uploading, some of which may have uploaded in the past. So when a file is uploaded, hash the file using MD5 and SHA1, and check if the file has already been uploaded. If has not, store it with randomly generated file name.

Random naming makes it difficult to find directly in the terminal, using this kind of upload procedure is not suitable for uniquely named files, like videos, musics, etc. In this case, upload by other method such as FTP or SFTP, and share it with remote file browser.
