[GHC] #8342: System.Directory.getPermissions does not work well on Windows 7
#8342: System.Directory.getPermissions does not work well on Windows 7 ---------------------------------------+--------------------------------- Reporter: freizl | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: libraries/directory | Version: 7.4.1 Keywords: | Operating System: Windows Architecture: x86_64 (amd64) | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ---------------------------------------+--------------------------------- It works well for following code {{{ System.Directory.getPermissions "/path/to/somewhere" }}} However getting error with this: {{{ System.Directory.getPermissions "/path/to/somewhere/" *** Exception: getPermissions: does not exist (No such file or directory) }}} The only difference is the path name. It gets error when having extra trailing slash. It looks wired.

Yes, I did that in my project. However I'm wondering the reason and hopefully there will be a fix. ;) Thanks. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8342#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I'll try to take a look tonight. Luckily, I have a windows box I can test on. I'm thinking that this is mainly just a problem how windows handles paths. https://github.com/ghc/packages- directory/blob/master/System/Directory.hs#L194 -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8342#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

"Does not exists" make little sense IMHO. Being strict is good idea and I suppose core library would do either of below when has slash at the end - Fixed it auto hence getPermissions show result correctly. - Display errors like "shall no have slash at the end" Suggestions/comments?
