Summary: [script] allow privoxy to work after resuming from sleep

Initial Comment:
$ cat /etc/pm/sleep.d/99.privoxy
#!/bin/bash
# Hooks to run privoxy after resume/thaw

. "${PM_FUNCTIONS}"

suspend_privoxy()
{
    /etc/rc.d/privoxy stop
}

resume_privoxy()
{
    /etc/rc.d/privoxy start
}

case $1 in
    hibernate|suspend)
        suspend_privoxy
        ;;
    thaw|resume)
        resume_privoxy
        ;;
    *) exit $NA
        ;;
esac

Since this script is rather distribution-oriented, I might suggest creating a folder in the root of the release for distro-specific data and placing this script there.
./distro/archlinux/99.privoxy
or
./distro/archlinux/etc/pm/sleep.d/99.privoxy

On the other hand, if anything can be done to make privoxy work after a thaw or resume, that would be much preferable.

Attached are the straces, two files:
privoxy.strace.no-s2ram.0
privoxy.strace.after-s2ram.0

and, if interesting:
$  ps aux | grep -i privoxy
privoxy  12450  0.0  0.0 183512  1908 ?        Ssl  19:40   0:00

Message:
I somehow missed the email from sourceforge. I should have both traces by
this weekend. 

If you'd like to duplicate, this is how I configured sleep on archlinux
[wiki @ http://wiki.archlinux.org/index.php/Pm-utils]

1] Configure the sleep backend to uswsusp
$  cat /etc/pm/config.d/module 
SLEEP_MODULE="uswsusp"
2] Review the suspend hooks in
"/etc/pm/sleep.d"
"/usr/lib/pm-utils/sleep.d/"

2*] Perhaps also review any files provided by the pm-utils package

3] Call suspend2ram by
"dbus-send --system --print-reply --dest=org.freedesktop.Hal
/org/freedesktop/Hal/devices/computer
org.freedesktop.Hal.Device.SystemPowerManagement.Suspend int32:0"

4] Which in turns calls as root
"/usr/sbin/pm-suspend"

This is suspend to RAM aka "pm-suspend". I've never used or configured
suspend to disk aka "pm-hibernate".

Message:
My attempts to reproduce this with Linux Mint failed so far. Privoxy seems
to work fine after resuming from suspend to RAM and the system itself
doesn't properly wake up from suspend to disk so I can't test this.

Can you provide the output of

strace -f -p `pgrep privoxy`

showing a properly handled request before suspending and a failed one
after resuming?

Reopen as this hasn't been properly analyzed yet.

We also got a similar report in:

Message:
The problem:
I use the uswsusp sleep module. If the laptop sleeps long enough, on
resume I need to restart privoxy to get internet access, otherwise privoxy
reports -> "The host could not be resolved" etc. This is only for privoxy:
other tools such as "ping", or browsers not using proxies, have no problem
accessing the network.

I'm not sure why there is a time factor: possibly dhcp lease timeout or
some other network quirk. I know "overnight" is long enough.

Message:
Thanks for the script but as you already mentioned it's
distribution-specific so my suggestion would be  that you send it to the
maintainer of the Archlinux Privoxy package.

As far as I know nobody around here is using Archlinux so we can't really
test or maintain it.

Could you describe the resume trouble you're having in more detail?
I'm not aware of any problems but I also don't use resume myself.
