#12494: Implementation of setenv in base incorrectly claims empty environment variable not supported on Windows -------------------------------------+------------------------------------- Reporter: ezyang | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by adamgundry): I'm inclined to agree that we could just change this, and mention in the new docs that the function had different behaviour in older versions of `base`. While we're at it, perhaps it is worth explicitly documenting the fact that `setEnv` is not thread safe? This may be obvious to others, but it wasn't to me, and has been causing segfaults in a production Haskell application. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12494#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
