How do I increase the buffer size for domain sockets in OS X 10.6
- by Chas. Owens
In Linux I have no problem dumping tons of data into a domain socket, but the same code on OS X 10.6.2 blows up after about 65 records. The socket reader code looks like
#!/usr/bin/perl
use strict;
use warnings;
use IO::Socket;
unlink "foo";
my $sock = IO::Socket::UNIX->new (
Local => 'foo',
Type => SOCK_DGRAM,
Timeout => 600,
) or die "Could not create socket: $!\n";
while (<$sock>) {
chomp;
print "[$_]\n";
}
And the client code looks like
#!/usr/bin/perl
use strict;
use warnings;
use IO::Socket;
my $sock = IO::Socket::UNIX->new (
Peer => 'foo',
Type => SOCK_DGRAM,
Timeout => 600,
) or die "Could not create socket: $!\n";
for my $i (1 .. 1_000_000) {
print $sock "$i\n" or die $!;
}
close $sock;
The error message I get is No buffer space available at write.pl line 15.. It seems fairly obvious that there is a difference in the buffer size between Linux and OS X, but I don't know how to set it OS X (or what the possible negative side effects might be).
