    getConfigStateFile: throw meaningful exceptions, recover old LBI · 78776496
    ttuegel authored
    getConfigStateFile now throws meaningful exceptions which are caught by
    tryGetConfigStateFile and friends, which are allowed to propagate,
    rather than just calling 'die'. If the LocalBuildInfo was generated by
    an older version of Cabal, an exception is still generated, but the
    LocalBuildInfo is included if it is recoverable. This feature is used to
    reduce code duplication between the library and the test suite.
