Remove select() use from FollowTail and Client::FTP disk I/O. This
will also disable the non-blocking flags.
Well I have delved more deeply. I'm concentrating on getting Client:FTP to
work; I like it much better than direct Net::FTP calls. I have found that
it uses POE::Wheel::SocketFactory, and that SocketFactory says:
# Don't block on socket operations, because the socket will be
# driven by a select loop.
# Do it the Win32 way. XXX This is incomplete.
It does indeed seems incomplete because I get:
ERROR: connect returned '10035/Unknown error' while trying to connect to
'172.20.245.73' at C:\RSA\agent\bin\sys-agent.pl line 412.
But only after I comment out:
# XXX EINPROGRESS is not included in ActiveState's POSIX.pm, and
# I don't know what AS's Perl uses instead. What to do here?
# if ($! and ($! != EINPROGRESS) and ($! != EWOULDBLOCK)) {
$poe_kernel->yield( $event_failure,
'connect', $!+0, $!, $self->[MY_UNIQUE_ID]
We know that:
eval '*EWOULDBLOCK = sub { 10035 };';
I am unclear why EWOULDBLOCK should not be logged since it does prevent the
connect from completing.
I am bedeviling myself by using Windows 2000 and "Binary build 631 provided
by ActiveState Tool Corp."
