Wajig displays incorrect new and upgradeable package count

I am failing to reproduce this. Are you able to?

I can reproduce it. The problem (in my case, anyway) is due to the fact that a package might be available from more than one source, and wajig is including all these in its calculation, while only one version of a package can be installed, of course.

I've written a bash script to simulate "wajig update", which I'm attaching. It doesn't issue "apt-get update", but works with the current apt and dpkg files. Then instead of displaying a count, it displays the problematical packages. It doesn't need root. When I run the script, I get:

bash wajsim
libmysqlclient16 5.1.61-0ubuntu0.11.10.1 5.1.58-1ubuntu5 5.1.61-0ubuntu0.11.10.1

Attaching extract from output of "apt-cache dumpavail" with duplicate entries for libmysqlclient16.

Looks as though this is a duplicate of bug 325002

It looks as though the problem is really that i386 and amd64 versions of a library or package might be installed, and these are counted separately. The versions might be found in the output from "apt-cache dumpavail" or in /var/lib/dpkg/status. On the other hand, "wajig toupgrade" doesn't discriminate between architectures and only shows the package once.

Attached is a patch to sort uniquely, so the counts from "wajig upgrade" match the count of lines from "wajig toupgrade".

Thanks a lot for this patient analysis.

I have just enabled multi-arch, so I can test this (I use Debian).

I committed to the VCS. You mind testing?

setup:
$ wajig install devscripts
$ hg clone https://wajig.googlecode.com/hg
$ cd wajig

build + install:
$ debuild -us -uc -b
$ sudo debi

Thanks, that looks good (I had to cd to hg, not wajig, and install debhelper as well).

I'd just make a small criticism (of my own work!) that I think the comment in update_evailable should be reformatted to fit into 80 columns.

Thanks much.
