The distributed-process-monad-control package

[ Tags: bsd3, control, library ] [ Propose Tags ]

This module exports instances for MonadBase IO and MonadBaseControl IO for the Process monad. This is for use in conjunction with a library requiring these instances, such as the lifted-base package.

A tutorial segment regarding use of this in distributed-process applications may be found here.

Please excercise caution in usage of this instance, as it can enable use of functions such as forkIO (or, fork from lifted-base) which compromise invariants in the Process monad and can lead to confusing and subtle issues. Always use the Cloud Haskell functions such as spawnLocal instead.

example usage:

import Control.Distributed.Process.MonadBaseControl()
import Control.Concurrent.MVar.Lifted (withMVar)

processWithMVar :: MVar a -> (a -> Process b) -> Process b
processWithMvar = withMVar

[back to package description]

distributed-process-monad-control

Orphan instances for MonadBase and MonadBaseControl. Please see the tutorial for an introduction and use case for these instances. Also please note that these instances enable the use of functions that are un-sound in the context of distributed-process. Functions such as forkIO (or, fork from lifted-base) compromise invariants in the Process monad and can lead to confusing and subtle issues. Always use the Cloud Haskell functions such as spawnLocal instead.

This repository is part of Cloud Haskell.

See http://haskell-distributed.github.io for documentation, user guides, tutorials and assistance.
