Re: [squid-users] rock & squid -k reconfigure

Hi,

investigating on this issue, it appears that the problem comes from
the "disker" ID in the SwapDir object.
Added these debug lines in SwapDir::active()

.......
// we are inside a disker dedicated to this disk
debugs(3,1,"SwapDir::active :: KidIdentifier = " << KidIdentifier <<
"disker = " << disker << "." );
    if (KidIdentifier == disker)
        return true;

........

it appears that the "disker" is wrong after running a squid -k
reconfigure, and hence the active() function returns false.

with a fresh start :

2013/03/22 11:30:29 kid3| SwapDir::active :: KidIdentifier = 3disker = 2.
2013/03/22 11:30:29 kid3| SwapDir::active :: KidIdentifier = 3disker = 2.
2013/03/22 11:30:29 kid2| SwapDir::active :: KidIdentifier = 2disker = 2.
2013/03/22 11:30:29 kid2| SwapDir::active :: KidIdentifier = 2disker = 2.
2013/03/22 11:30:30 kid3| SwapDir::active :: KidIdentifier = 3disker = 2.
2013/03/22 11:30:30 kid3| SwapDir::active :: KidIdentifier = 3disker = 2.
2013/03/22 11:30:30 kid2| SwapDir::active :: KidIdentifier = 2disker = 2.
2013/03/22 11:30:30 kid2| SwapDir::active :: KidIdentifier = 2disker = 2.

with

[root_at_tv alex]# ps aux|grep squid

root 20320 0.0 0.0 1182724 2096 ? Ss 11:30 0:00 squid
-f /etc/squid/squid.conf
proxy 20322 0.1 0.2 1183196 11220 ? S 11:30 0:00
(squid-coord-3) -f /etc/squid/squid.conf
proxy 20323 0.0 0.2 1184180 11640 ? S 11:30 0:00

proxy 20324 0.0 0.2 1188276 11484 ? S 11:30 0:00
(squid-1) -f /etc/squid/squid.conf

after issuing the squid -k reconfigure, the output of the ps is
identical, but the diskerID is set to 3.

2013/03/22 11:31:46 kid3| SwapDir::active :: KidIdentifier = 3disker = 3.
2013/03/22 11:31:46 kid2| SwapDir::active :: KidIdentifier = 2disker = 3.
2013/03/22 11:31:46 kid2| SwapDir::active :: KidIdentifier = 2disker = 3.
2013/03/22 11:31:47 kid3| SwapDir::active :: KidIdentifier = 3disker = 3.
2013/03/22 11:31:47 kid3| SwapDir::active :: KidIdentifier = 3disker = 3.
2013/03/22 11:31:47 kid2| SwapDir::active :: KidIdentifier = 2disker = 3.
2013/03/22 11:31:47 kid2| SwapDir::active :: KidIdentifier = 2disker = 3.

Trying to trace the problem futher, the "disker" ID seems to be given
in the contructor of the SwapDir,

SwapDir::SwapDir(char const *aType): theType(aType),
        max_size(0), min_objsize(0), max_objsize (-1),
        path(NULL), index(-1), disker(-1),
        repl(NULL), removals(0), scanned(0),
        cleanLog(NULL)
{
    fs.blksize = 1024;
}

Any hints on where is the right call for creation ( or re-creation )
of this object after a reconfigure?

Thanks
Alex
