Package: dpkg
Version: 1.16.10
Severity: wishlist

Hi,

In light of <[email protected]>, I would like
to request dpkg -f and dpkg-deb -f would work without writing a
temporary file to the disk.

Currently, Lintian uses its own "ar | tar"-pipeline because "dpkg-deb
-f $file is very slow"[1].  The comment does not specify what causes
the slowness.
  As far as simple benchmarks have shown me, there seem
to be no real difference between dpkg-deb -f and "ar | tar"
performance-wise (with /tmp being tmpfs).  So I guess that the only
(remaining?) problem is the extraction to disk.
