The build takes about one hour.
Wow, that’s much less than I thought.
that’s faster than `perf.haskell.org`… Can we run it on every commit
It's only building a bit more than half of all Stackage Nightly right now, because 5 packages currently fail and those are dependencies for the rest. We expect that all told, on the "xlarge" CircleCI machine types, a full Stackage build should take around 2 hours. That's just an extrapolation though. Reality might be quite a bit worse (or better). then?
Or, maybe a bit less wasteful: Run it every few hours, but if there is a
difference, then automatically schedule additional runs of the commits in between to bisect the change? It's currently set at running every 6 hours, and only using GHC master. But I agree, running it at every commit could well be viable. Let's iterate on this as we get more experience using it. :) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15022#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
