Debugging

reload

• --reload
• False

Restart workers when code changes.

This setting is intended for development. It will cause workers to be restarted whenever application code changes.

The reloader is incompatible with application preloading. When using a paste configuration be sure that the server block does not import any application code or the reload will not work as designed.

The default behavior is to attempt inotify with a fallback to file system polling. Generally, inotify should be preferred if available because it consumes less system resources.

Note

In order to use the inotify reloader, you must have the inotify package installed.

reload_engine

• --reload-engine STRING
• auto

The implementation that should be used to power reload.

Valid engines are:

• ‘auto’
• ‘poll’
• ‘inotify’ (requires inotify)

• --spew
• False
