A full-fledged configuration file parser in varnishd?

The problem is that if you define DAEMON_OPTS, none of the other knobs
work, right? FreeBSD at least has that issue:
: ${varnishd_enable=NO}
: ${varnishd_listen=:6081}
: ${varnishd_config=%%PREFIX%%/etc/varnish/default.vcl}
: ${varnishd_telnet=localhost:6082}
: ${varnishd_storage=file,/tmp,50%}
: ${varnishd_flags=-P ${pidfile} -a ${varnishd_listen} -f ${varnishd_config}
-T ${varnishd_telnet} -s ${varnishd_storage}}
if you define varnishd_flags, you have to specify everything manually,
since the other knobs only serve to populate the default value for
varnishd_flags.
Of course, we could introduce a varnishd_extra_flags knob that just
gets appended to varnishd_flags... not very elegant, though.

Re: Setting default_ttl in vcl file
I take this off varnish-misc as it is quite distro specific. * Ingvar Hagelund The RedHat and Debian init scripts reads default values from their respective defaults file, that is, for RedHat, /etc/sysconfig/varnish, and for Debian, /etc/defaults/varnish. * Dag-Erling Smørgrav The problem is that if you define DAEMON_OPTS, none of the other knobs work, right? FreeBSD at least has that issue: if you define varnishd_flags, you have to specify everything manually, since the other knobs only serve to populate the default value for varnishd_flags. At least for RedHat, there are no other knobs. All the startup configuration is in the file. There are no hard coded values in the init script. The init script won't start varnishd if DAEMON_OPTS is empty, or the config file does not exist. if [ $DAEMON_OPTS = ]; then echo \$DAEMON_OPTS empty. echo -n Please put configuration options in /etc/sysconfig/varnish echo_failure The configuration file is fairly documented with the most used options, and points to the manpage for more advanced users. I would not know if this is suitable for FreeBSD ports, but I think it's quite a clean method to ensure that the user knows what she wants to change before changing it. As for myself, I dislike magic invisible default values.

Hello,
I have just started to use varnish and was looking into the default
cache time of an object / item, etc. I know the default_ttl is 120
seconds and I was looking to change that to 3600 seconds. From the
documentation and previous mail archives I have found three ways to
set this. Two ways are through the rc.d and rc.conf files and the
last is through the vcl.
A. /usr/local/etc/rc.d/varnishd file
Create a variable called varnishd_ttl and set it to 3600.
: ${varnishd_ttl=3600}
Edit varnishd_flags and add my new variable
: ${varnishd_flags=-P ${pidfile} -a ${varnishd_listen} -f $
{varnishd_config} -T ${varnishd_telnet} -s ${varnishd_storage} -t $
{varnishd_ttl}}
B. /etc/rc.conf
Create a variable called varnishd_ttl and set it to 3600.
: ${varnishd_ttl=3600}
Edit varnishd_flags and add my new variable
varnishd_enable=YES
varnishd_listen=mb-prv.kcilink.com:80
varnishd_storage=file,/var/tmp,512M
varnishd_config=/usr/local/etc/varnish/morebiz.vcl
varnishd_ttl=3600
varnishd_flags=-P ${pidfile} -a ${varnishd_listen} -f $
{varnishd_config} -T ${varnishd_telnet} -s ${varnishd_storage} -t $
{varnishd_ttl}
c. /usr/local/etc/varnish/default.vcl
*if (obj.ttl 3600s) {
set obj.ttl = 3600s;
}
*not exact just scratch code.
Now my question, is there a more direct way to change the default_ttl
either through configuration files or .vcl file? If these are pretty
much the only three ways that is fine, I just wanted to make sure I
wasn't skipping over any options. Thank you in advance for your help.
Steve
