[Build-common-hackers] Bug#399308: cdbs-edit-patch creates incorrect patches when simple-patchsys.mk and tarball.mk are in use

[Bryan Donlan]

Package: cdbs
Version: 0.4.47
Severity: normal

When both tarball.mk and simple-patchsys.mk are in use, cdbs-edit-patch
creates patches which require patchlevel 3 to apply. However,
simple-patchsys only tries 1, 0, and 2.

An example package is here:
http://etc.uguu.us/onscripter-insani_20060724-CDBS_BUG.tbz2

Both patches in debian/patches were created by cdbs-edit-patch and will not
apply when built. cdbs-edit-patch will also fail for any patch after
these; and generate similarly flawed patches.

One workaround is to add
cdbs_simple_patchsys_levels = 1 0 2 3
to debian/rules.
