(a DGRAM IPC channel could also work, but delivery is not guaranteed on all platforms) One benefit of switching to using a normal IPC channel is that the need for comm_quick_poll_required() would go away, also getting rid of the related 400KB/s cache hits issue under low loads..

ntlm_auth Negotiate support
Hi Andrew, I have a question for the Samba team. The current STABLE Squid version (2.6) supports the Negotiate authentication schema, but for now it can be used only when running on native Windows, because Samba 3 ntlm_auth doesn't provide such support. There is any expectation about adding this support to Samba 3, or we need to long wait for Samba 4 ? They are already many requests about from Squid users.

Hi Steven,

I have just found another bug. I have ended up in the situation where
squid has not stared the diskd processes (because the binary is called
diskd-daemon not diskd_daemon). Squid is not serving any web pages,
and will not stop because of this, but is is stuck in a loop doing the
following:
epoll_wait(3, {}, 256, 10) = 0
gettimeofday({1154236711, 528040}, NULL) = 0
msgrcv(1409029, {0,

IPC_NOWAIT) = -1 ENOMSG (No message of desired type)
epoll_wait(3, {}, 256, 10) = 0
I think that likely you have found the problem, look the log attached
to this Squid bug on Debian opened by the same people:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=380020
2006/07/26 16:52:21| ipcCreate: /usr/lib/squid/diskd_daemon: (2) No
such file or directory
The problem seems to be into ipcCreate():
Currently only the child can know if the program to be launched exist.
What about about to add a check of the existence of the program before fork() ?
Regards
Guido
