[Pkg-ia32-libs-maintainers] Bug#531515: Processed: Re: Bug#531515: ia32-apt-get: breaks "dpkg --control" (>= 1.15.1) and debsums

[Goswin von Brederlow]

Hi,

thank you for starcing the problem. Too me it looks like debsums calls
dpkg-deb in an undocumented (although not uncommon for tools in
general) way:

4: /usr/bin/dpkg-deb --control -- /var/cache/apt/archives/bzip2_1.0.5-2_amd64.deb /tmp/gD4mFRK2gm/DEBIAN

According to the manpage the syntax is:

        -e, --control archive [directory]

There is no mention in the docs that dpkg-deb supports "--". Maybe
because it is such a common option.

Your patch isn't correct though, at least not complete. Think of this
invocation:

dpkg-deb --control -- /var/cache/apt/archives/bzip2_1.0.5-2_amd64.deb

In that case, despite having 3 arguments, the DIR has to default to
$(pwd)/DEBIAN. I guess there is no way around fully scanning the
arguments and counting the valid bits. That should allow the use of
the "-D" option as well.

MfG
