[Bug 1886725] [NEW] RM haskell-gitlib FTBFS due to MonadFail

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Dimitri John Ledkov (xnox):

ghc has fully deprecated and removed MonadFail proposal, requiring code
to be rewritten.

Git/Types.hs:144:14: error:
    • Could not deduce (MonadFail m) arising from a use of ‘fail’
      from the context: Monad m
        bound by the type signature for:
                   textToSha :: forall (m :: * -> *). Monad m => Text -> m SHA
        at Git/Types.hs:140:1-37
      Possible fix:
        add (MonadFail m) to the context of
          the type signature for:
            textToSha :: forall (m :: * -> *). Monad m => Text -> m SHA
    • In the expression: fail "Invalid base16 encoding"
      In a case alternative: _ -> fail "Invalid base16 encoding"
      In the expression:
        case B16.decode $ T.encodeUtf8 t of
          (bs, "") -> return (SHA bs)
          _ -> fail "Invalid base16 encoding"
    |
144 |         _ -> fail "Invalid base16 encoding"
    |              ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

haskell-gitlib still uses the deprecated "fail" which is no longer
exposed by MonadFail.
