CloseHandle: invalid argument on Windows

snoyberg commented 6 years ago

When working on the fsnotify-conduit test suite, I ran into seemingly unrelated errors on Windows. I was able to reduce it to the following test case:

#!/usr/bin/env stack
-- stack --resolver lts-11.8 script
import System.FSNotify
import System.Directory
import UnliftIO (tryIO, withSystemTempDirectory)

main :: IO ()
main =
  withSystemTempDirectory "fsnotify-test" $ \dir ->
  withManager $ \man -> do
    stop <- watchDir man dir (const True) print
    stop

This results in the output:

 CloseHandle: invalid argument (The handle is invalid.)

Thanks for the report @snoyberg -- this fix will go out when I release version 0.3.0.0
