All,

With the inclusion of the debug option in pacman 4.1.0, I think it makes sense to do something with this in the official repositories. I've sifted through some bug reports asking for inclusion of the debug symbols in a separate package or repository officially for testing purposes. With [extra] and [community] approaching 1.5 and 2 megabytes respectively, I think that adding debug symbols directly into these repositories would be a bad idea as it would probably add ~50% to those databases, and I've already seen some people complain about the sizes.

This doesn't belong to the pacman mailing list (I'm forwarding to arch-dev-public and arch-general), but I'll summarize what will probably happen: Separate debug repositories won't happen - we can't even put split packages into different repositories, so it is unlikely that we'll support separate debug repositories - and I don't see the need. Even if the db sizes double, we are still way under 5MB per db, which is a reasonable size considering our users' bandwidth nowadays. Allan stated that he'll add a glibc-debug package to core, and it is also likely that KDE will get debug packages in extra (they have been requested a few times).

DB size is not the only consideration. For example -Ss output will be "polluted". Allan

Fair enough.

It's not only the size of the database. I can see the problem with the size of repositories if someone keeps a mirror to save bandwidth if they have lots of computers, but they don't need debug packages. On 15 April 2013 10:11, Allan McRae wrote:

Maybe it could be filtered on the pacman side, ie. add some switch that would enable/disable showing of -debug packages. Lukas

Not keen on that... The issues that prevent split packages going across repos are entirely different to what is required to keep a separate debug package repo. In fact, I will provide the needed patches for a separate [debug] and [community-debug] repo if that is what is decided to happen. Allan

I personally think that is the only way to go about it. I wouldn't want -debug packages to take up search output, but I'd want them to exist somewhere accessible. An immediate possibility is to simply duplicate buildscripts to the debug repos and push only debug packages there. Of course, that'd be a manual process, and stuff won't be in sync/integrated, but it does mean that it's not anything impossible given our current packaging infrastructure. -- GPG/PGP ID: C0711BF1

You have my full support when it comes to having debug packages in a separate repository. On 15 April 2013 15:00, Tom Gundersen wrote:

Couldn't pacman be fixed to only show debug packages in search results when you ask for it with a switch? Maybe something similar could be done for language packages?

A simple alias/wrapper using grep on the pacman output would work too ;-)

Yeah, so why make a separate repo? What's the problem with keeping debug packages in the normal repos? -t

Thanks,

Allan already said he'll do the work (probably some work in devtools and dbscripts), so I don't particularly care anymore - once the work is done, I can live with a separate debug repo.
