Bug#574944: apt_preferences(5): "Pin-Priority:" line not optional

[Ansgar Burchardt <ansgar@2008.43-1.org>]

Package: apt
Version: 0.7.25.3
Severity: normal
File: /usr/share/man/man5/apt_preferences.5.gz

Hi,

apt_preferences(5) contains the following statement:

  The Pin-Priority: line in each APT preferences record is optional. If
  omitted, APT assigns a priority of 1 less than the last value
  specified on a line beginning with Pin-Priority: release ....

This is not true.  Records not containing a Pin-Priority field are
ignored with a warning:

      short int priority = Tags.FindI("Pin-Priority", 0);
      if (priority == 0)
      {
         _error->Warning(_("No priority (or zero) specified for pin"));
         continue;
      }
  (from apt-pkg/policy.cc)

Regards,
Ansgar
