Pkg xen devel - Jul 2009 - Bug#538683: xen-common: FTBFS with new source format 3.0 (quilt): fails to copy .pc due to files with 000 permissions

Package: xen-common
Version: 3.3.1-1
Severity: wishlist
Usertags: 3.0-quilt-by-default

To prepare a possible switch to the new source package format "3.0
(quilt)" [1], I converted all source packages and rebuilt the packages
afterwards to see what breaks, and xen-common does break. To reproduce the
problem you can do this:
$ apt-get source xen-common
$ mkdir -p xen-common-3.3.1/debian/source
$ echo "3.0 (quilt)" >xen-common-3.3.1/debian/source/format
$ dpkg-source -b xen-common-3.3.1
$ dpkg-source -x xen-common_3.3.1-1.dsc
$ cd xen-common-3.3.1 && debuild -us -uc

In this process, if the .diff.gz contains changes to upstream files,
dpkg-source will have created a corresponding patch in
debian/patches/debian-changes-3.3.1-1 and will have registered that
patch in a quilt series (debian/patches/series, it is created if needed).
All the patches listed in the "series" file are applied directly
during
the extraction (dpkg-source -x). quilt itself is used if available (and
will thus lead to the creation of the .pc directory), otherwise
dpkg-source applies the patches by itself. For more information about the
new source package format see the manual page dpkg-source(1).

In the case of xen-common, the process of copying the .pc directory in the
build dir fails because quilt stores files with 000 permissions when it
creates a new file from scratch.
