I'm switching my GHC development over to a Mac, and so I'm establishing a validation baseline, since I don't expect all tests to pass on my setup. After a ./sync-all pull (as of Johan's ade1ae97), and a ./validate --slow, I see unexpected results for these tests. TEST="T149 T5313 jules_xref launchbury layout008 jl_defaults T7360 T1969 T5631 T3064 T4801 T3294 jules_xref2 ImpSafeOnly08 safePkg01 ImpSafeOnly02 ImpSafeOnly03 ImpSafeOnly01 ImpSafeOnly06 ImpSafeOnly07 ImpSafeOnly04 ImpSafeOnly05 ImpSafeOnly09 ImpSafeOnly10 T4474a T4474c T4474b space_leak_001 conc058 conc068 conc065 conc066 conc020 conc035 conc017 rittri lex T2507 haddock.Cabal T7478 jq_readsPrec IntegerConversionRules integerConstantFolding signals004 T7170 dynamic003 length001 echo001 cgrun071 hSetBuffering004 hSetBuffering002 hClose002 andy_cherry qq007 qq008 recomp006" (See below for more of the summary info.) Question 1: To other GHC developers using OS X: do you recognize these tests as "unexpecteds expected on OS X"? Question 2: Has anyone diagnosed these particular tests? IE is there an OS X tsar? (I am not necessarily volunteering here.) Thanks. ----- T149 became a pass with one my patches about a month ago, but I was seeing nondeterminism and was hoping someone more familiar with the T149 test If I run the testsuite manually (cd testsuite/tests/; make TESTS=<as above>), the "ImpSafeOnly*" tests pass as expected. The 'conc*' tests don't even compile because block and unblock were replaced by mask, but I'm weary of directly changing this because it seems like these should have shown up on all platforms. I've lightly investigated some of the others, and opened a few tickets (#7876 #7877, comment on #7684), but I'm asking here for more information before I flood the ticket system. A common culprit seems to be the IO library's behavior wrt to closed handles. Other tests look to involve some dynamic linking issues.
