Travis build should be deterministic #30

Closed gracjan closed 8 years ago

gracjan commented 8 years ago

It seems that TravisCI somehow does not produce deterministic builds. master branch at https://travis-ci.org/haskell/haskell-ide-engine/builds/89591048 compiles, after a useless change in README a pull request does not compile https://travis-ci.org/haskell/haskell-ide-engine/builds/89742925. It ends up with a warning in HaRe:

    src/Language/Haskell/Refact/Utils/Monad.hs:211:10: Warning:
      No explicit implementation for
          ‘GM.gmoAsk’
        In the instance declaration for ‘GM.GmOut (StateT RefactState IO)’

Build system must be reliable and deterministic.

It seems the problem was an OOM error when compiling HaRe. A new version has been released which compiles with -O0, reducing memory usage. This is now no longer a problem,
