Bug ID: 395296
Summary: [kio_iso] Reading files on ISO images reads the ISO
image file from the beginning
Product: krusader
Version: 2.7.0
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: krusader-bugs-n...@kde.org
Reporter: alpha0...@yahoo.de
CC: krusader-bugs-n...@kde.org
Target Milestone: ---
Loading file data from an ISO image via the ISO KIO Slave reads the ISO image
file from the beginning every time. For big image files this is a huge waste of
time and resource. The cause seems to be the usage of KArchives's
KCompressionDevice[1], for which the authors have not bothered to implement a
random access mechanism. Instead, seeks are realized as reads from the
beginning. Would QFile[2] be a better alternative for uncompressed image files?
