Description Didier Colle 2017-08-19 19:50:55 UTC
I am trying to emerge dev-haskell/stack. Apparently only ebuild for stack-1.3.2 is available. This ebuild contains in RDEPEND: >=dev-haskell/tls-1.3.8:=[profile?] <dev-haskell/tls-1.4:=[profile?]
I assume this is the reason why I was suggested (and which I did) to add amongst many many more things the following to my package.accept_keywords file:
# required by dev-haskell/stack-1.3.2::gentoo
# required by stack (argument)
=dev-haskell/tls-1.3.9 ~x86

dev-haskell/connection-0.2.4 is indirectly pulled in by emerging stack.
The build of connection-0.2.4 fails: see complete build.log below.
The relevant part is:
Network/Connection.hs:316:12:
    Couldn't match type ‘TLS.Context’ with ‘IO TLS.Context’
    Expected type: RNG.ChachaRNG -> IO TLS.Context
      Actual type: RNG.ChachaRNG -> TLS.Context
    The function ‘TLS.contextNew’ is applied to three arguments,
    its type is ‘backend0 -> params0 -> m0 TLS.Context’,
    it is specialized to ‘Handle
                          -> TLS.ClientParams -> RNG.ChachaRNG -> TLS.Context’
    In a stmt of a 'do' block:
      ctx <- TLS.contextNew handle tlsParams rng
    In the expression:
      do { rng <- RNG.initialize
                  <$> grabEntropyIO 40 (globalEntropyPool cg);
           ctx <- TLS.contextNew handle tlsParams rng;
           TLS.handshake ctx;
           return ctx }

From https://hackage.haskell.org/package/tls-1.2.18/docs/Network-TLS.html :
contextNew Source
:: (MonadIO m, CPRG rng, HasBackend backend, TLSParams params)	 
=> backend	Backend abstraction with specific method to interact with the connection type.
-> params	Parameters of the context.
-> rng	Random number generator associated with this context.
-> m Context	 

And from hhttps://hackage.haskell.org/package/tls-1.3.0/docs/Network-TLS.html :
contextNew Source
:: (MonadIO m, HasBackend backend, TLSParams params)	 
=> backend	Backend abstraction with specific method to interact with the connection type.
-> params	Parameters of the context.
-> m Context	 

Thus between version 1.2(.18) and 1.3(.0) the TLS API has changed in the signature of the contextNew function.

In the dev-haskell/connection-0.2.4.ebuild RDEPEND contains >=dev-haskell/tls-1.2:=[profile?] . As such, connection-0.2.4 is happy with tls-1.3.9 (although unmasked in accept_keywords file) pulled in by emerging stack.

Simply limiting the connection-0.2.4 RDEPEND to <dev-haskell/tls-1.3.0 might look attractive as solution, but is not good enough as I assume it will prohibit me emerging stack which was my intention in the first place ...

Comment 1 Sergei Trofimovich gentoo-dev 2017-08-26 10:15:02 UTC
I suggest using the same keywording policy for all dev-haskell/* ebuilds like 'dev-haskell/* ~x86'.

Thanks for the report! I'll all upper bound to dev-haskell/connection-0.2.4
