[GHC] #9945: export list for System.Posix.Internals breaking the build on Windows

That would restore the old behaviour from before the export list was added, anyway. I'm working on a patch to that end now. Shouldn't take long.

I really thought I'd checked the CPP reasonably well, but this is the second failure. The real question is whether these conditionally- defined names are used outside the module, or whether they're intended only for internal use. If the latter, they just shouldn't be exported at all. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9945#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I've already discovered `is_console` was missing from the export list entirely, but CPP-conditionally used in `GHC.IO.FD.isTerminal`: {{{#!hs isTerminal :: FD -> IO Bool isTerminal fd = #if defined(mingw32_HOST_OS) if fdIsSocket fd then return False else is_console (fdFD fd) >>= return.toBool #else c_isatty (fdFD fd) >>= return.toBool #endif }}} I note it's used there `#if defined(mingw32_HOST_OS)`, but its definition in `System.Posix.Internals` is `#if !defined(HTYPE_TCFLAG_T)` - that doesn't seem right, but I don't know enough about what those constants mean to say what should be done about it (if anything). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9945#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

The patch below "fixes" it, but it is obviously Not Right. Various functions are defined under THREE different sets of conditions * `#if !defined(HTYPE_TCFLAG_T)` * `#if !defined(mingw32_HOST_OS)` * `#if !defined(mingw32_HOST_OS) && !defined(__MINGW32__)` They should presumably be just one set of conditions? Anyway it would be great if someone could fix it properly.

It turns out (after much `git grep -w`) that almost all of those conditional definitions are module-internal anyway. After dropping those from the export list, this is my diff (to be composed with the one I pasted above): {{{ diff --git a/libraries/base/System/Posix/Internals.hs b/libraries/base/System/Posix/Internals.hs index d316826..ea24ec3 100644 --- a/libraries/base/System/Posix/Internals.hs +++ b/libraries/base/System/Posix/Internals.hs @@ -39,17 +39,12 @@ module System.Posix.Internals s_issock, setCooked, setEcho, setNonBlockingFD, sizeof_stat, st_dev, st_ino, st_mode, st_mtime, st_size, statGetType, withFilePath, #if !defined(mingw32_HOST_OS) && !defined(__MINGW32__) - c_fcntl_lock, c_fcntl_read, c_fcntl_write, c_fork, c_link, c_mkfifo, - c_pipe, c_s_issock, c_sigaddset, c_sigemptyset, c_sigprocmask, - c_tcgetattr, c_tcsetattr, c_utime, c_waitpid, setCloseOnExec, + c_pipe, setCloseOnExec, #endif #if !defined(mingw32_HOST_OS) peekFilePathLen, #endif -#if defined(HTYPE_TCFLAG_T) - c_lflag, get_saved_termios, poke_c_lflag, ptr_c_cc, set_saved_termios, - sizeof_sigset_t, sizeof_termios, tcSetAttr, -#else +#if !defined(HTYPE_TCFLAG_T) is_console, #endif ) where }}} That compiles for me. As for the remaining conditional exports... `c_pipe`:: Only used in `GHC.Event.Control.newControl`. I node that module imports it unconditionally - but it seems all of `GHC.Event` is only used in non-Windows environments (if I'm reading `libraries/base/base.cabal` correctly), so that's fine. `setCloseOnExec`:: Also used in `GHC.Event.Control.newControl`, but additionally in `GHC.Event.EPoll.epollCreate`. `peekFilePathLen`:: Only used in `System.Environment.ExecutablePath.readSymbolicLink`, and only `#if defined(linux_HOST_OS)`. `is_console`:: As above, only used in `GHC.IO.FD.isTerminal`, and only `#if defined(mingw32_HOST_OS)`. So am I right in thinking, for the ones that are only used in one place, the solution would be to just move the `foreign import` to the point-of- use? That'd just leave `setCloseOnExec` (used in two places) - would `GHC.Event.Internal` be a good place for that one? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9945#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
