HttpUploadComponent

The HttpUploadComponent is a plugin extension to your XMPP server that allows users to upload files to a HTTP host and eventually share the link to those files.

It runs as a stand alone process on the same host as your XMPP server and connects to that server using the Jabber Component Protocol.

A detailed introduction into the necessity of such a component and the simple protocol can be found on the XMPP Standards email list.

Configuration

Configuration happens in config.yml and is pretty straight forward.

component_jid, component_secret and component_port have to match the corresponding entries in your XMPP server config (Refer to the documentation of your server).

whitelist should contain a list of domains and/or users whos JIDs are allowed to upload files. Remove the entry if you want to allow everyone (not really recommended).

get_url and put_url are prefixes to the URLs. The put_url is usually a combination of your hostname and the port (Port can be ommited if HTTP default ports are being used) The GET URL can use a different host if you want to serve files using a standard nginx or another HTTP server that might be more suitable for serving files than a python script.

For security purposes you should put the python script behind an HTTPS proxy or stunnel (remember to adapt the URLs). For quicker results you can also use the built in TLS encryption by setting http_keyfile and http_certfile in the config file.

For the configuration of the XMPP server side have a look into the contrib directory or check the server documentation.

Expiry and user quotas

Expiry and user quotas are controlled by four config options:

expire_interval determines how often (in seconds) files should be deleted. As every expiry run needs to check all uploaded files of all users this should not be set too small.

Files older than expire_maxage (in seconds) will be deleted by an expiry run. Set this to 0 to disable deletions based on file age.

After an expiry run at most user_quota_soft space (in bytes) will be occupied per user. The oldest files will be deleted first until the occupied space is less than user_quota_soft. Set this to 0 to disable file deletions based on a users occupied space.

user_quota_hard sets a hard limit how much space (in bytes) a user may occupy. If an upload would make his files exceed this size it will be rejected. This setting is not dependend on expire_interval. Set this to 0 to disable upload rejection based on occupied space.

expire_maxage and user_quota_soft depend on expire_interval.

user_quota_hard is honoured even without expiry runs. But some kind of expiry is recommended otherwise a user will not be able to upload anymore files once his hard quota is reached.

The difference between user_quota_hard and user_quota_soft determines how much a user may upload per expire_interval.

Run

Running the component is as easy as invoking python server.py

Some (unoffical) init scripts can be found in the contrib directory. Feel free to write your own init scripts if necessary and contribute them back by creating a pull request.

Clients

Currently the only client with built in support is Conversations where it is being used to send files to Multi User Conferences and to multiple resources in 1 on 1 chats.
