It does make sense on the laptop (sometimes), but not so much in the CI env. This is an assumption that may break if we end up having any corrupt or failing packages in the cache. It also make it hard to "go back in time" if we want to test without some update. (Cleaning corrupt caches an re-running is easy in a local setting, in CI you end up dealing with angry devs getting false '-1's) It could be faster, but could also be slower if you end up fetching more then you have to. (if engine setup fails on missing dependency, you just spent needless time fetching VDSM dpes) Also fetching by itself may not be the bottleneck in all cases, it is surely slow when fetching from PHX to TLV, but when fetching from the Squid proxy's RAM inside PHX it can actually end up being faster then copying from the local disk. I wonder how many of those minutes are spend on fetching things we actually need, and how much is spent on overhead. I suspect that without a local cache, the test run will be longer, but not as long as the pre-fetching+tests takes currently. More importantly, this may allow the CI to fail faster. I think we should at least test that. Maybe we can take a middle ground, pre-fetch, but also enable external repos in CI (perhaps with some way to log and find out what was not pre-fetched). -- Barak Korren bkorren(a)redhat.com RHEV-CI Team
