[Bug 1048091] Re: dh_python3: TypeError when maximum version is specified

[IRIE Shinsuke]

I encountered the problem in my Blender's PPA:

  ppa:irie/blender

You can see build log of the FTBFS:

  https://launchpad.net/~irie/+archive/blender/+build/3876314

Since Blender requires many libraries which are not officially
debianized yet, you have to use some other PPAs if you want to test my
blender package:

  ppa:irie/opencollada-builddep
  ppa:irie/ocio-static
  ppa:irie/openimageio (optional, maybe Ubuntu's offical package can be used instead)

Anyway, as I mentioned in Debian's tracker, each element of vr[] in
depends.py is a tuple of the major and minor versions such as (3, 2),
not an integer, so "vr[1] + 1" in the line 158 absolutely causes a
TypeError.

Title:
  dh_python3: TypeError when maximum version is specified

Bug description:
  Package: python3-defaults
  Version: 3.2.3-5

  I was building a deb package using python3 in my PPA.  I want to
  specify a range of python3 version, but dh_python3 causes an error as
  follows if the maximum version is specified:

  Traceback (most recent call last):
    File "/usr/bin/dh_python3", line 490, in <module>
      main()
    File "/usr/bin/dh_python3", line 422, in main
      dependencies.parse(stats, options)
    File "/usr/share/python3/debpython/depends.py", line 158, in parse
      self.depend("python3 (<< %s)" % vrepr(vr[1] + 1))
  TypeError: can only concatenate tuple (not "int") to tuple

  I specified the python3 version in debian/control as follows:

    X-Python3-Version: >= 3.2, << 3.3

  The same error happens when I use -V command line option like:

    dh_python3 -V 3.2-3.3

  I'm using dh_python3 only for private modules, not for public modules.
