[jira] [Created] (DAEMON-204) Support sending a reload message via
SIGUSR2
Support sending a reload message via SIGUSR2
---------------------------------------------
Key: DAEMON-204
URL: https://issues.apache.org/jira/browse/DAEMON-204
Project: Commons Daemon
Issue Type: Improvement
Components: Jsvc
Environment: linux/unix
Reporter: Nick Griffiths
Priority: Minor
Fix For: 1.0.6
I've often wanted to be able to support config reloading (like apache's or nginx's soft reload) in our daemons, so I've been hacking around with jsvc to see how difficult it would be to add. It seems to have been quite easy to do it via signals (patch attached), but I'm not confident with the low level c-stuff.

[jira] [Resolved] (DAEMON-204) Support sending a reload message via
SIGUSR2

Mladen Turk resolved DAEMON-204.
--------------------------------
Resolution: Fixed
Committed the modified version of your patch.
I have mostly changed its purpose to be be a generic signaling solution.
Once the signal is received it is up to the user to decide what action will be performed. It can be like in your case a softReload or a complex failover if the SIGUSR2 represents a OS condition (like low disk space, etc...)
Anyhow, many thanks for the patch!
