Hello All,
has anyone encountered the problem described here:
http://bugs.activestate.com/show_bug.cgi?id=82846
If you look at perldoc perlport, it claims that
socketpair isn't
implemented on Win32.
socketpair
Not implemented. (Win32,
RISC OS, VOS, VM/ESA)
So I'm surprised it works when you fork/socketpair even
once.
Moreover, if you look at perldoc perlfork, you'll see
that fork on
Win32 is emulated using Perl threads and there are some
cautions in
there about sockets, pipes, etc. I suspect that it's
the second fork
that's causing the problem, but couldn't give you more
specific
guidance than that.
Best of luck,
David
Well, if 'socketpair' is not implemented as the documentation says, then
it's another bug.
I tried something not implemented from POSIX module, and the attempt ended
up in getting something like not implemented in your OS error message.
Actually, just moving lines around I think I can make the code work - the
following:
1 #!/usr/bin/perl -w
2
3 # pipe2 - bidirectional communication using socketpair
4 # the best ones always go both ways
5 use Socket;
6 use IO::Handle; # thousands of lines just for autoflush :-(
7 # We say AF_UNIX because although *_LOCAL is the
8 # POSIX 1003.1g form of the constant, many machines
9 # still don't have it.
10
11 use strict;
12
13 my $child_fh;
14 my $parent_fh;
15 socketpair($child_fh, $parent_fh, AF_UNIX, SOCK_STREAM, PF_UNSPEC) or
die socketpair: $!;
16
17 $child_fh-autoflush(1);
18 $parent_fh-autoflush(1);
19 my $pid;
20 if($pid = fork)
21{
22close $parent_fh;
23print $child_fh Parent Pid $$ is sending this\n;
24chomp(my $line = $child_fh);
25warn Parent Pid $$ just read this: '$line';
26close $child_fh;
27waitpid($pid,0);
28}
29 else
30{
31die cannot fork: $! unless defined $pid;
32close $child_fh;
33chomp(my $line = $parent_fh);
34warn Child Pid $$ just read this: '$line';
35print $parent_fh Child Pid $$ is sending this\n;
36close $parent_fh;
37
38 {
39 my $child_fh;
40 my $parent_fh;
41 socketpair($child_fh, $parent_fh, AF_UNIX, SOCK_STREAM, PF_UNSPEC)
or die socketpair: $!;
42

works under both Linux and Windows; under Windows the code prints negative
PIDs due to, I think, threads IDs rather then PIDs.
So, even two forks can work.
Any further ideas ?
Thanks,
Sergei.
(fork + pipe + pipe) x 2 doesn't work under Windows, works under Linux
Hello All, this is kind of follow-up on (fork + socketpair) x 2 doesn't work under Windows, works under Linux reported earlier. This time I modified the example with 'pipe' rather than 'socketpair', and according to 'man perlport' there are no special comments WRT Win32, i.e. I guess one can assume that 'pipe' is implemented under Windows. The details are here: http://bugs.activestate.com/show_bug.cgi?id=82870 . Any ideas/suggestions ? Thanks, Sergei.
