Description:
The agent does not process SIGHUP.

It should close and reopen all files on reception of sighup to better integrate with logrotate.

How to repeat:
Find PID of agent.
Send SIGHUP.
See what happens.

Suggested fix:
Handle SIGHUP as demons should handle it.

For 2.0 the logfile rotation has been changed to log the progress of the rotation:

At startup:

  2008-06-09 12:58:50: (message) mysql-proxy 0.7.0 started

When a SIGHUP is received:

  2008-06-09 12:59:05: (message) received a SIGHUP, rotating logfile

The new logfile gets:

  2008-06-09 12:59:05: (message) rotated logfile

At shutdown:
   
  2008-06-09 12:59:44: (message) shutting down normally
