Dear GHC-Team,
to improve the quality of Haskell on Debian started to package the GHC testsuite in a package of its own, and will upload it to Debian so that it runs on all architectures and catches possible architecture-dependent bugs there.
Using the released testsuite for 7.0.4 with that version of the compiler, and running it with SKIPWAY="optc profc optllvm" fast=YES I get this result:
OVERALL SUMMARY for test run started at Sa 7. Jan 17:45:54 CET 2012 2612 total tests, which gave rise to 10986 test cases, of which 0 caused framework failures 8642 were skipped
2267 expected passes 59 expected failures 0 unexpected passes 18 unexpected failures
Unexpected failures: 3586(normal) Chan001(normal) MVar001(normal) QSem001(normal) QSemN001(normal) SampleVar001(normal) T1969(normal) T3064(normal) T3087(normal) T3294(normal) T4316(ghci) T4801(normal) cgrun025(normal) driver027(normal) driver028(normal) ghci014(ghci) ghcpkg05(normal) regex003(normal)
Is that normal to find unexpected failures of the release testsuite on a “normal” system?
Unfortunately yes, but we are getting better in this area. Here's where we stand on the 7.4 branch for our major platforms currently: x86_64/Linux: 1 unexpected failure x86/Linux: 33 unexpected failures x86/Windows: 65 unexpected failures x86_64/Mac: unknown (no nightly build?) In fact the majority of these failures are just bugs in the tests or the test suite framework, and keeping the testsuite clean takes quite a lot of effort, which is why it's hard to get motivated to do it. But I agree it's important, especially for a release, to have zero failures. So I've made a ticket to do this for 7.4.1: http://hackage.haskell.org/trac/ghc/ticket/5757
Should I file bug reports about unexpected failures found in the latest testsuite, once I get around to package and run that?
Sure, please do.
And a minor request, in case someone feels like touching the test driver: It would be nice if the summary lists all library packages that are not installed but required by some test, i.e. the libraries that ought to be added to the Build-Dependency of the test suite to get a more complete coverage.
Yes, good idea. I recently changed the driver so that it now prints out the number of failures due to missing dependencies, but it doesn't print out which packages are required, that would be a good improvement. Cheers, Simon
I could not attach the build log, as it is too large, but you can find it here: http://people.debian.org/~nomeata/ghc-testsuite_7.0.4-1_amd64.build.gz
Thanks, Joachim
