Thread and Net::SSH::W32Perl
Hi,
I am trying to implement small multi threaded SSH application, on a IIS6.
Code works fine without the Threads.
But I get SSH'ish looking error when trying to use Threads.
Can anyone offer any advice what I might be doing wrong? Perhaps a working
example or a link to one.
Below is the output of my code followed by simplified perl code I run.
Thanks
Mark
Btw, I have Perl v5.8.7 built for MSWin32-x86-multi-thread, with
usethreads=define use5005threads=undef useithreads=define
usemultiplicity=define

FW: process output pipe autoflush
Many thanks to $Bill, Carl and Michael,
The cause was the buffering in the executable involved,
I had the coder insert fflush(stdout) after each printf statement.
Also my understanding on buffering has somewhat improved.
Thanks again.

Hello,
I have a problem with autoflush. Platform is Windows NT 4 / sp6.
I use the following code:
$command = 'executable.exe param1 ';#option 1
# $command = 'DIR C:\ /S'; #option 2
open (PIPE, "$command |");
$| = 1;
while (PIPE){
print;
}
If I use line with (option 2) the output does not get buffered as
expected.
If I use line with (option 1) the output of the executable is buffered.
If I execute the line "executable.exe param1" on the DOS prompt
the oputput is produced immediately.
I tried both autoflush PIPE and select((select(PIPE), $| = 1)[0])
commands,
I even print out the value of $| during execution, it is set to 1.
What am I doing wrong?
How do you know the data is being buffered or not?
Are you doing this under CGI conditions?
Do you understand what buffering does?
It basically forces each line out individually (when $| is set) rather
then waiting for an internal buffer (maybe 512/1024 bytes??) to fill before
outputting. Leaving STDOUT buffered ($| not set) is more efficient.
If you were to slip a sleep 1 into your loop, you would see the result
since one would print one line every second and the other would wait several
seconds and then print several lines.
