I've just compiled and install squid-1.1.0 on our Linux proxy cache. It
works fine, but it thinks the number of file descriptors it can open is
1024 which it isn't, as I run an unpatched kernel it's 256.

This piece of code from squid.h causes problems:


It's used before any other file is included so FD_SETSIZE is not defined
eg 0, and this is _always_ true. Now on Linux FD_SETSIZE is 1024
but the maximum no. of file descriptor per process is 256.

I think the safest solution would be to make squid_maxfd a variable
instead of a constant, initialized as squid_maxfd = SQUID_MAXFD in main().
Then when we much around with getrlimit() and setrlimit() in tools.c
we can set squid_maxfd to the real kernel maximum.

I'll create some patches to squid-1.1.0 later this week if noone has
done that yet.
