[Pkg-mc-devel] Bug#805495: mc: Very slow opening of an ISO file

[Brian Potkin]

Package: mc
Version: 3:4.8.13-3
Severity: normal


genisoimage is a suggested package for mc and isoinfo (from the package)
is used to open an ISO archive and display the files in it. The display
is almost instantaneous with DVD-2 for Jessie.

mc is also capable of using xorriso for the same job. If xorriso is also
on the system it takes over from isoinfo. I do not know whether this
could be classed as a bug.

Whether or not genisoimage has been installed the opening of an ISO is
very, vary slow using xorriso; in excess of a minute on this machine.

  xorriso -indev debian-8.2.0-i386-DVD-4.iso -lsl

Output from

  xorriso -indev debian-installer/debian_isos/debian-8.2.0-i386-DVD-4.iso -lsl

is immediate, as is

  xorriso -indev debian-installer/debian_isos/debian-8.2.0-i386-DVD-4.iso -lsl pool/main

I'd conclude xorriso is not at fault.

Regards,

Brian.
