Hi people,
I'm using:
Apache/1.3.33 mod_perl/1.29
On a Debian Sarge system.
The code I'm having problems with is quite long, so I've written a cut down version. In my virtual host block I have something along the lines of:
<Location /test.tar>
SetHandler perl-script
PerlHandler My::Handler
</Location>Basically, you go to /test.tar and a tarball is returned by My::Handler. However, it is generated on the fly like:
# Get the content-length: my( $command ) = "/bin/tar -c -h -f /dev/null --totals the_directory 2>&1"=~/^(.+)$/; `$command` =~ /Total bytes written: (\d+)/gsm;
# Send the content-length
$r->header_out('Content-Length', $1 );# Open a "filehandle" to the tar command ( $command ) = "/bin/tar -c -h -f - the_directory 2>/dev/null"=~/^(.+)$/; open my $filehandle,"$command |";
# Send the data: $r->send_fd( $filehandle );
# Close the filehandle close $filehandle;
The problem is, when someone hits stop in their web browser and ends the transfer prematurely, the tar command doesn't die like I'd hoped it would. I'm assuming here that I'm missing something basic in my knowledge of how modperl works...
Thank you in advance for any help.
P.S. I included the content-length part just in case anyone knew of a better way to calculate the size a tarball is going to be before it is actually generated...
