Rendering Binary Data

[Martin Onegu]

Hey there,

i've got some binary data (in fact it is a pcap file content) in my $res scalar and within my controller i do the following let this content be downloaded by the browswer.

    $self->res->headers->content_type('application/x-download');

    $self->res->headers->content_disposition("attachment; filename=$id.bin;");

    return $self->render(data => $res);

Whats going wrong is that the binary that i download with (different) browsers is different than the original data, the md5_hex($res) is different then md5sum on my file on console.

When looking closer on the content, downloaded and original data, i see that there are some bytes in the beginning that differ (though they have the same size, which is extra confusing)

/tmp % head -n 2 download.hex result.hex

==> download.hex <==

0000000: c394 c383 c2b2 c2a1 0200 0400 0000 0000  ................

0000010: 0000 0000 c3bf c3bf 0000 0100 0000 68c2  ..............h.

==> result.hex <==

0000000: d4c3 b2a1 0200 0400 0000 0000 0000 0000  ................

0000010: ffff 0000 0100 0000 6889 dd55 b7da 0100  ........h..U....

% ls -l 290028E2-50B7-11E5-9379-5C5CF516A027.bin

Hello,

i was able to figure out that this bug actually is only in combination with the morbo webserver.

If I am using something else => everything works as ecpected.

If I am using morbo like that:

$PERL -I ../lib -I "${BASEDIR}/lib" $MORBO \

    -l "https://*:${DEFAULT_PORT}?cert=/...../server.crt&key=/........./server.pem" \

    $DEFAULT_SCRIPT

Its broken!!

If i am using morbo like that:

$PERL -I ../lib -I "${BASEDIR}/lib" $MORBO \

     -l "http://*:${DEFAULT_PORT}" \

$DEFAULT_SCRIPT

its working fine as well!

    return $self->render(data => $res);

This should work, Mojolicious does not modify the value.
