Really? I thought it was supposed to be standard behaviour- the @stopdaemon line in pkg-plist facilitates that.
While I totally understand why we do this, I have to say it's VERY VERY annoying behavior especially when one upgrading a remote system with multiple server daemon ports. One have to watch the whole process carefully and restart the daemon manually.
Yep, and even more annoyingly is that it is completely inconsistent: some daemons are stopped, some not, etc.
We do not currently have a standard procedure for that, nor do we record the necessary state -- perhaps we should just discuss, vote, and add a paragraph to the porter's handbook.
We also need to bring the authors (or volunteers) for the de-facto standard upgrade tools into the loop.
My thoughts:
- give the user a choice to configure whether to restart services
- optional: give the users a chance to configure this per-service
- discuss whether we want/need to support this (a) in the framework that we currently use, (b) only in pkgng, (c) in portmaster and portupgrade where necessary.
Or we could have a facility to check whether services are running. For example, I have some cron scripts, which are similar for all of the services that I'm watching. They run periodically and restart services if they are down. It does not matter if they are down because of an upgrade or a failure, so this solution is more general. Here's an example that I have for MySQL:
#!/bin/sh PID_FILE="/var/db/mysql/server.mypc.hu.pid" PID=`cat $PID_FILE` EXECUTABLE="/usr/local/etc/rc.d/mysql-server start"
if test -r $PID_FILE ; then # pidfile exist, is it correct? if kill -CHLD $PID >/dev/null 2>&1; then # ok, exit silently exit 0 fi rm -f $PID_FILE fi echo "" echo "Couldn't find the MySQL server running, retsarting.." echo "" $EXECUTABLE
