Package: squid
Version: 2.7.STABLE3-4.1
Severity: wishlist
Tags: patch
If in squid.conf the location of the pid-file is non standard, squid will not
restart and the
logrotate will not work correctly.
I propose to move some parameters form the start-stop script to
/etc/default/squid.
1. Add to /etc/default/squid:
...
NAME="squid"
SQUID_CONF="/etc/squid/squid.conf"
SQUID_ARGS="-D -YC -f ${SQUID_CONF}"
PIDFILE=$(awk '\
BEGIN { FS=" "; pidfile=sprintf("/var/run/%s.pid", NAME) }
$0 ~ /^pid_filename/ { pidfile=sprintf("%s", $2) }
END { print pidfile} ' $SQUID_CONF)
SQUID_UID=$(awk '\
BEGIN { FS=" "; squid_uid="proxy" }
$0 ~ /^cache_effective_user/ { squid_uid=sprintf("%s", $2) }
END { print squid_uid} ' $SQUID_CONF)
SQUID_GID=$(awk '\
BEGIN { FS=" "; squid_gid="proxy" }
$0 ~ /^cache_effective_group/ { squid_gid=sprintf("%s", $2) }
END { print squid_gid} ' $SQUID_CONF)
2. Change /etc/init.d/squid to
DAEMON=/usr/sbin/squid
LIB=/usr/lib/squid
[ ! -f /etc/default/squid ] || . /etc/default/squid
. /lib/lsb/init-functions
3. Change /etc/logrotate.d/squid to
...
postrotate
if [ -f "`. /etc/default/squid ; echo ${PIDFILE:-/var/run/squid.pid}`" ]
then
/usr/sbin/squid -k rotate
fi
endscript
Additional wishes:
With SQUID_UID en SQUID_GID it is possible to check permissions of the logfile,
the cache
and other files
