README
haskell-sharedio
Allows "bundling" or "throttling" of concurrent IO to perform computation only once.
Useful in situations where concurrency can be expensive, such as file system scans (where concurrent execution usually returns the same result but introduces much disk seeking overhead).
Example
import Control.Concurrent.SharedIO (SharedIO, newSharedIO, withSharedIO)
-- A webserver that lists directory contents, using
-- SharedIO to bundle clients fanatically hitting refresh.
-- Without this, the file seeking would slow the server to a crawl.
main = do
fileScanSharedIO <- newSharedIO
runWebserver (handleRequest fileScanSharedIO)
handleRequest :: SharedIO -> IO [FilePath]
handleRequest fileScanSharedIO = do
withSharedIO fileScanSharedIO (getDirectoryContents "largefolder")
