Thanks for the quick reply, Stas.  I tried it out and that particular

whereas as a normal CGI it does.  I didn't notice any errors, but valid
pages just don't validate under mod_perl (they do as normal CGI).  I
know this is a too vague explanation, but I don't have time to dig
deeper now.


As I said, the IPC::Open* family is usually not working under mod_perl (1.0 
and 2.0). Nobody has looked into resolving this issue, mainly because IPC::Run 
seems to be a much better alternative. But that doesn't solve the problem for 
those who are stuck with an existing code and aren't able to adjust it. 
Therefore since IPC::Run provides the same functionality and more, may be a 
special IPC::Open* layer can be provided which will transparently replace 
IPC::Open* with IPC::Run.

Hi,

The script below under mod_perl 1.99_08 (ModPerl::Registry), gives me
this:

  Can't locate object method "FILENO" via package
  "Apache::RequestRec" at /usr/lib/perl5/5.8.0/IPC/Open3.pm line 196.

A real world example of a script that has these problems is the W3C
Markup Validator,
.

The validator works under mod_perl 1, and I guess the test script would
as well (I'm unable to verify that at the moment, though).  Maybe a
mod_perl 2 bug/missing feature?

My installation is Red Hat 8.0, Apache 2.0.40, mod_perl 1.99_08 and Perl
5.8.0.  The test script:

  use IPC::Open2 qw(open2);
  use IO::File ();
  my $in  = IO::File->new_tmpfile();
  my $out = IO::File->new_tmpfile();
  print $in "foobar\n";
  seek $in, 0, 0;
  print "Content-Type: text/plain\n\n";
  my $pid = open2($out, $in, 'tee');
  undef $in;
  waitpid $pid, 0;
  seek $out, 0, 0;
  while (<$out>) {
print;
  }
  undef $out;
