Bug#1055969: kuttypy: reproducible-builds: shell-dependent use of echo

[Vagrant Cascadian]

Source: kuttypy
Version: 2.1.1-2
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: shell
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

Newlines are handled differently depending on which shell implementation
is in use, resulting in differences dependent on the build environment:

  https://tests.reproducible-builds.org/debian/rb-pkg/bullseye/amd64/diffoscope-results/kuttypy.html

  /usr/share/kuttypy/utilities/build_details.py

  QT_VERSION·=·'PyQt5'\nPY_VERSION·=·3\n
  vs.
  QT_VERSION·=·'PyQt5'	 
  PY_VERSION·=·3

The attached patch fixes this in the upstream Makefile by making
multiple echo calls rather than relying on the shell-dependent echo
handling of "\n".

With this patch applied to kutty 2.1.1-4, based on my local tests,
kuttypy should build reproducibly on tests.reproducible-builds.org!


Thanks for maintaining kuttypy!


live well,
