FUNCTIONS

pause_vivaldi

Usage:

 pause_vivaldi(%args) -> [status, msg, payload, meta]

Pause (kill -STOP) Vivaldi.

A modern browser now runs complex web pages and applications. Despite browser's power management feature, these pages/tabs on the browser often still eat considerable CPU cycles even though they only run in the background. Stopping (kill -STOP) the browser processes is a simple and effective way to stop CPU eating on Unix. It can be performed whenever you are not using your browsers for a little while, e.g. when you are typing on an editor or watching a movie. When you want to use your browser again, simply unpause it.

This function is not exported.

Arguments ('*' denotes required arguments):

• users => array[unix::local_uid]

  Kill browser processes that belong to certain user(s) only.

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)

Usage:

 ps_vivaldi(%args) -> [status, msg, payload, meta]

Check whether Vivaldi is paused.

Vivaldi is defined as paused if all of its processes are in 'stop' state.

vivaldi_is_running

Usage:

Check whether Vivaldi is running.

Vivaldi is defined as running if there are some Vivaldi processes that are not in 'stop' state. In other words, if Vivaldi has been started but is currently paused, we do not say that it's running. If you want to check if Vivaldi process exists, you can use ps_vivaldi.
