4:41 PM Changeset in directory [b513fe8]encodingghc-7.2ghc-7.4ghc-7.6ghc-7.8patch-5014 by Duncan Coutts <duncan@…>
Fix createDirectoryIfMissing to not throw if the dir got deleted When we call createDirectory and some file system object already exists we have a problem. We need to distinguish if it is a file that already exists or if it is a directory because in the latter case it is not an error. Previously we called doesDirectoryExist however that does not distinguish the dir not existing (due to another thread deleting it) and an ordinary file existing. We now use withFileStatus to throw the original AlreadyExistsError only if a non-directory object exists. So now the only time we should get a spurious exception is if another thread deletes the directory and puts a file in its place between our call to createDirectory and withFileStatus. It should now be safe to race createDirectoryIfMissing with itself or deleteDirectoryRecursive.

Do not use System.Process on Posix systems We were using System.Process.Internals, which isn't safe in general. Also, when the child process dies with a signal, we now raise the same signal ourselves.
