[Pkg-octave-devel] Bug#538623: octave-epstk: FTBFS with new source format 3.0 (quilt): fails double build

[hertzog at debian.org]

Package: octave-epstk
Version: 2.2-14
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 octave-epstk does break. To reproduce the
problem you can do this:
$ apt-get source octave-epstk
$ mkdir -p octave-epstk-2.2/debian/source
$ echo "3.0 (quilt)" >octave-epstk-2.2/debian/source/format
$ dpkg-source -b octave-epstk-2.2
$ dpkg-source -x octave-epstk_2.2-14.dsc
$ cd octave-epstk-2.2 && 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-2.2-14 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 octave-epstk, it doesn't build twice in a row and since the
code above build the source package twice, it leads to the same failure.
Not sure exactly why...
