The vast majority of issues are related to a package update causing broken deps for something needed in something release blocking. So, I would start there and setup gating to check for broken deps and require waving that test or fixing the deps. The next most common issue is core tools changing that we use to compose (lorax, anaconda, kernel, glibc). For those we are intending to try and make 'quick composes' that compose something quickly and test it to catch common/simple issues. Then we go from there. > If you propose just doing some fast automated tests catching some issues, > that will never reliably catch all issues breaking the composes, and so my > proposals to increase the robustness of the compose process will still be > relevant.

The problems I see with just shipping whatever we compose: * It means things will likely be broken longer as there is less urgency to fix them quickly. * There's cascading issues where issue A stops composing of items 1, 2, 3, 4 and each of those have further issues, so it means we don't even know what all is broken. * Shipping things out means we can't easily untag or revert packages with using Epoch's much more commonly. * It will mean we are not in fact always shipping alpha quality, we could be shipping anything. * reactive just is a lot harder in the end, IMHO. > It is just defensive programming to not fail the whole process on any small > issue that you cannot avoid (with the resources that are available).
