Backend activity

Backend activity is a soft approach to the problem of concurrent editing of the same content. It provides a block which shows the admin paths other users are currently working on and highlights them, if they match with the path the current user is working on.

To accomplish that it uses an HTML Web Worker thread (see: http://www.w3.org/TR/workers/) which sends a ping like signal via AJAX every few seconds to update the activity stream. If no ping comes in for a defined period of time the user probably closed the browser. This information will automatically be pushed to other clients.

It also comes with an overview, which shows what every logged in user is up to right now.

This module only provides additional information and does not lock content editing in any way. Also please note, that all editor's browsers will need to support webworkers, please check this list here.
