[GHC] #9912: Allow access to full logs in Harbormaster builds

#9912: Allow access to full logs in Harbormaster builds -------------------------------------+------------------------------------- Reporter: goldfire | Owner: hvr Type: bug | Status: new Priority: normal | Milestone: Component: Trac & Git | Version: 7.8.3 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Blocked By: | None/Unknown Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Harbormaster helpfully tries building every commit and every differential revision. However, when it fails, we only get the tail of the output, with no way to get more information. A case in point is [https://phabricator.haskell.org/harbormaster/build/2736/ this build], where a performance test case failed with `[stat too good]`. In this particular case, the commit is intended to be an optimization, so this failure is not terribly unexpected. I wanted to update `all.T` with the new figure, but I couldn't get the figure that Harbormaster's configuration had. Instead, I had to run the test on my machine (a Mac), get a different number, and hope that Harbormaster's configuration fell within 5% of mine. It did, in this case, but might not next time. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9912> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
