Bug#573592: absent debian revision is not considered equivalent to 0
Package: apt
Version: 0.7.25.3
Severity: normal
According to Policy 5.6.12 the absence of a debian revision should be
considered equivalent to the presence of a debian revision of 0 (this
was clarified somewhere in 2008).
dpkg apparently works this way but apt does not:
$ python
Python 2.5.5 (r255:77872, Feb 2 2010, 00:25:36)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import apt_pkg
>>> apt_pkg.init()
>>> apt_pkg.VersionCompare("1.0", "1.0-0")
-1
>>>
(python-apt's VersionCompare is just a python wrapper around apt's
actual implementation)
