Not that I disagree, but let me elaborate on what that would entail. 1) All the stuff that already happens today for updates. This takes roughly an hour or so to get the set of updates signed and the push started. The push itself takes roughly 7-8 hours with f9,f10,f11 testing and stable. I'm already pushing updates almost 5 days a week, so doing it more frequently isn't going to help much. Particularly when there are typically between 70-150 pending updates every day. The mash time only grows as the repos grow larger from new packages. 2) In addition to 1 above, we'd now have to run a depcheck on the resulting repos. If it finds no problems, great! Continue with the push. If it has dependency issues, fail. Take the packages that have dep errors, and automatically revoke those update requests in bodhi. The start over again. Except it's not that easy. Because in order to mash the repos, we need the packages to move tags in koji. So now we have to roll back those tag operations too. And we also have to trim those packages out of the push list. The bodhi state machine cannot cope with any of this today. I don't believe dep checking can be done on update submission (at least not easily), because in order to do that we need a repo to run it against and the update might be relying on other pending updates that aren't in the repos yet. The way to get them in the repo is to mash it... (Doing test/throw-away mash->dep checks would just be sort of silly due to the time it takes and the ever fluctuating pending updates list). 3) We would need some significant code changes to bodhi and possibly mash to get all of that. That code is thoroughly understood by exactly 1 person. Another person (me) is trying to grok it in his spare time, but it's rather involved and the bodhi setup on the infrastructure machines is a bit convoluted. Having people jump in to help would be awesome, but it is not a trivial task. So it's easy to say "we should dep check before pushing". And I'll even agree we should. However, in reality there is a _lot_ of work that needs to be done to make that even remotely possible. I'm certainly open to other suggestions on how to accomplish this. I would love if someone would tell me how stupid I am and how it can be done more easily. However, I am growing slightly tired of people saying we should 'do it' (or worse, ranting about it) without having a clue on what needs to be done to actually do it or even volunteering to help. Hopefully those that want to see this happen will read over the strawman above and put some collective brain/muscle power behind it. josh -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
