Restarting a daemon

it sends the terminate signal to the old myserver. If so, what is the correct way to restart the daemon? Will it work to run the restart command in a subprocess rather than a subshell or will a subprocess also terminate when its parent terminates? -- Jeffrey Barish -- http://mail.python.org

Re: Single-instance daemons

root at cleanup as it's stored as your saved UID. Nice. One thing: how do I get the uid and gid for the target user? In general, I know the name of the target user, but the uid/gid assigned by the OS to that user could be different on different systems. -- Jeffrey Barish -- http

Re: Sending Python statement over socket in chunks

I have to carve up the list as source. Using Pyro to send the chunks once I have them should work fine. Note that I am avoiding the use of the term slice. It is not possible to slice the list in the way that we normally do in Python because it is still in the form of a string. -- Jeffrey Barish
