Fwd: Bug#477386: devscripts: [debcheckout] should check for repository on unstable

Hi there!

Yesterday evening I found a bug in debcheckout/devscripts, which
actually is caused by how `apt-cache showsrc $PKG` returns the different
versions (testing -> unstable -> experimental -> stable), completely
different from `apt-cache policy $PKG` (read below for examples).

It seems that I'm the only one who considers this as a bug: is there any
rationale behind this?  And why not showing the same output as
`apt-cache policy $PKG`?

I decided to not cc: the BTS, but feel free to do so if you think it's

Thx, bye,
Gismo / Luca

in case the output below wouldn't be self-explicative, it seems that
`apt-cache showsrc $PKG` doesn't return unstable versions first, which
renders debcheckout quite useless if you have more than unstable in your
apt sources.

I filed the bug to devscripts after a discussion on #d-devel:
[22:09:21] <gismo> why `apt-cache showsrc $PKG` returns versions in a
		   different order than `apt-cache show $PKG`?  i.e.,
		   not starting the latest in unstable
[22:09:49] <gismo> not starting FROM the..., obviously
[22:10:21] <madduck> they use two different indices
[22:11:16] <gismo> madduck: well, this renders `debcheckout -a`
		   completely useless (and it's a bug IMHO)
[22:11:24] <madduck> uh oh
[22:11:27] <madduck> file it...
[22:11:32] <eigood> that's not a bug in apt
[22:11:42] <gismo> eigood: why?
[22:11:46] <gismo> madduck: devscripts or apt?
[22:11:47] <eigood> there is nothing that says what order apt should
		    output things in
[22:11:52] <madduck> gismo: devscripts
[22:11:57] <gismo> eigood: consistency?
[22:12:00] <gismo> madduck: thx
[22:12:07] <eigood> and, even then, what is available thru a 'deb'
		    line may not be in sync with a 'deb-src' line
[22:12:40] <eigood> deb .... main
[22:12:46] <eigood> deb-src ... pool ....
[22:12:50] <eigood> deb-src .... contrib
[22:12:55] <eigood> deb .... non-free
[22:12:58] <eigood> deb-src ... main
[22:12:59] <gismo> eigood: sure, but at least I'd like to have the
		   same order for both (i.e., from the more recent to
		   the oldest)
[22:13:00] <eigood> etc
[22:13:18] <gismo> eigood: anyway, I'm filing it for devscripts and
		   let's see then
[22:13:22] <eigood> er, the second is supposed to be from snapshot
[22:14:22] <gismo> eigood: can I quote you on the bug report?
[22:14:38] <eigood> sure
[22:14:55] <gismo> eigood: thx
[22:15:08] <eigood> instead of having 2 lines, with main contrib
		    non-free, both deb/deb-src, an admin may split
		    those, and put them in some odd order
[22:15:20] <eigood> in an ideal world, you could have 2 options in
		    such cases:
[22:15:37] <eigood> order based on sources.list, or alphabetical
[22:15:53] <madduck> increasing version number
[22:16:20] <eigood> but in any event, it's not specified what should
		    be done
[22:16:44] <gismo> eigood: it's neither of based on sources.list nor
		   alphabetical: it's testing -> unstable -> stable
[22:20:13] <gismo> madduck: BTW, can I quote you, too?
[22:20:24] <madduck> always
[22:20:44] <madduck> though i didn't really contribute anything, did
		     i? :)
[22:21:54] <gismo> madduck: at least the choice of the package to file
		   the bug to ;-)

Thx, bye,
Gismo / Luca
