[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

[GHC] #9976: Ignore newlines in code diffs on Phab

#9976: Ignore newlines in code diffs on Phab -------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: feature | Status: new request | Milestone: Priority: low | Version: 7.8.4 Component: Trac & Git | Operating System: Unknown/Multiple Keywords: | Type of failure: None/Unknown Architecture: | Blocked By: Unknown/Multiple | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Doing code reviews in Phab is great. However, the way that the lint feature works encourages patchers to split lines as they means that more attention is drawn to split lines than perhaps should be. As a concrete example, I'm reading Phab:D538 this morning, and looking at line 402 of !DsArrows. Alan has added a new field to a data structure and needed to insert a `_` to make the code remain well typed... but this forced a line split to avoid a lint error. Now, I have to check if there are any changes in the second half of the line manually, because the character-diff highlighting fails after the line split. Is there a way to improve this behavior? I can think of two approaches: * (Better option) Teach the character-diff highlighting feature to look across linebreaks. * (Worse option) Encourage patchers ''not'' to make new line breaks until their final commit. Suppress lint problems about line breaks by request. This is, of course, minor, but it would certainly be nice! -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/9976> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
