[debhelper-devel] Bug#820711: dh_compress: fails if the debian directory is a symlink

[Bernhard Miklautz]

Package: debhelper
Version: 9.20160403
Severity: important

Dear Maintainer,

if the debian folder is a symlink to a directory, a call to
dh_compress, directly or during a build, causes an error.

For example if the package "nightly" has a debian folder
that is symlinked to packaging/deb/nightly/ the following error will be raised during a debuild

chmod: cannot access '../../packaging/deb/nightly/nightly/usr/share/doc/nightly/changelog': No such file or directory
dh_compress: chmod a-x ../../packaging/deb/nightly/nightly/usr/share/doc/nightly/changelog returned exit code 1

It seems that the paths aren't calculated properly. This happens since dephelper version 9.20160306.
