I can verify for you that this is a problem.
You wouldnt happen to be using Apache::Filter would you?
I've posted this problem at least once over the past year, and I have seen it
posted by others. I had this porblem trying to oepn3() a pipe to gnupg and
encrypt some data. I later switched to the "GnuPG::Tie" package and had similar
problems.
After much head scratching I figured out that I was using Apache::Filter and I
needed to first untie STDIN and STDOUT before I could make things work.
My ugly hack around it basically was this:
my ($stdin, $stdout);
if (lc $this->request->dir_config('Filter') eq 'on') {
# undo Apache::Filter mess.
$stdin = tied *STDIN;
$stdout = tied *STDOUT;
untie *STDIN;
untie *STDOUT;
}
.... use GnuPG::Tie::Encrypt to encrypt data ...
if (lc $this->request->dir_config('Filter') eq 'on') {
# now retie STDIN, STDOUT for Apache::Filter
tie *STDIN, ref $stdin, $stdin;
tie *STDOUT, ref $stdout, $stdout;
}
I havent tried a similar solution for IPC::Open3, but you may want to try this
if you are using Apache::Filter.
Its not pretty, but it works for me :).
