Hi all,
We now have an automated program for performing regression tests against
all of hackage:
darcs get http://darcs.haskell.org/hackage-test/
An example of how to use it:
Here's a run with the HEAD, no special options:
$ ht normal ../cabal-install/dist/build/cabal/cabal \
/home/ian/ghc/darcs/ghc/inst/bin/ghc \
/home/ian/ghc/darcs/ghc/inst/bin/ghc-pkg \
"" ""
[7.75 hours pass]
Then another run, this time using -XAlternativeLayoutRule to compile
each package (but not the build dependencies of the package):
$ ht alternative ../cabal-install/dist/build/cabal/cabal \
/home/ian/ghc/darcs/ghc/inst/bin/ghc \
/home/ian/ghc/darcs/ghc/inst/bin/ghc-pkg \
"" \
"--ghc-option=-XAlternativeLayoutRule"
[7 hours pass]
And finally a comparison of the results:
$ htc normal alternative
normal
Buildable Build failed Deps failed Not tried
alternative Buildable 628 0 0 0
Build failed 73 215 0 0
Deps failed 0 0 170 0
Not tried 0 0 0 0
i.e. 73 packages became unbuildable when the alternative layout rule was
used.
Thanks
Ian
