Reiser is not good idea for squid cache. Why ? Squids cache is hashed by default to minimize "big directory effect". Reiserfs is fast on realy big directories, but it eat more cpu than ext2. On high loaded cache servers cpu utilization on reiser can be realy big. Better way is make more subdirectories in squid cache, and use filesystem, that eat less of cpu. -- Daniel Podlejski <[EMAIL PROTECTED]> ...

Incorect signal handling ?
Hi,
there is litlle programm:
#include
#include
#include
#include
#include
#include
#include
static void empty(int sig)
{
printf ("hello\n");
return;
}
void main()
{
int fd, a;
char buf[512];
if (fd = open("/tmp/nic", O_RDONLY) < 0)
{
perror ("open");
exit(1);
}
signal (SIGALRM, empty);
alarm (1);
a = read(fd, buf, 511);
while (a && a != -1) a = read(fd, buf, 511);
if (a == -1)
{
perror ("read");
exit(1);
}
else printf ("EOF\n");
exit(0);
}
I open /tmp/nic and run compiled program.
There should be error EINTR in read, but isn't.
Why ?
