Changelog for unix package

2.7.2.2 May 2017

• Bundled with GHC 8.2.1

• Fix error message of createSymbolicLink (#84)

2.7.2.1 Nov 2016

• Bundled with GHC 8.0.2

• Don't use readdir_r if its deprecated.

• Add argument documentation for Env modules

2.7.2.0 Apr 2016

• Bundled with GHC 8.0.1

• Don't assume non-POSIX WCOREDUMP(x) macro exists

• Don't assume existence of termios(3) constants beyond B38400

• Don't assume existence of ctermid(3)/tcdrain(3)

• Change drainOutput's tcdrain(3) into a safe FFI call

• Turn build error into compile warnings for exotic struct stat configurations (GHC #8859)

2.7.1.0 Dec 2014

• Bundled with GHC 7.10.1

• Tighten SafeHaskell bounds for GHC 7.10+

• Add haddock comments on RTLD_NEXT and RTLD_DEFAULT

• Deprecate function haveRtldLocal

• Fix getGroupEntryForID/getGroupEntryForName on Solaris. Solaris uses CPP macros for required getgrgid_r and getgrnam_r functions definition so the fix is to change from C ABI calling convention to C API calling convention

• Fix potential type-mismatch in telldir/seekdir FFI imports

• Use CAPI FFI import for truncate to make sure the LFS-version is used.

• executeFile: Fix ENOTDIR error for entries with non-directory components in PATH (and instead skip over non-directory PATH-elements)

• New functions in System.Posix.Unistd:

  • fileSynchronise (aka fsync(2)), and
  • fileSynchroniseDataOnly (aka fdatasync(2))

• New module System.Posix.Fcntl providing

  • fileAdvise (aka posix_fadvise(2)), and
  • fileAllocate (aka posix_fallocate(2))

• Fix SIGINFO and SIGWINCH definitions

2.7.0.1 Mar 2014

• Bundled with GHC 7.8.1

• Handle EROFS and ETXTBSY as (non-exceptional) permission denied in fileAccess

• Fix getFileStatus to retry stat(2) when it returns EAGAIN (this can happen on Solaris)

2.7.0.0 Nov 2013

• New forkProcessWithUnmask function in the style of forkIOWithUnmask

• Change forkProcess to inherit the exception masking state of its caller

• Add new Bool flag to ProcessStatus(Terminated) constructor indicating whether a core dump occured

• New functions in System.Posix.Files{,.ByteString} for operating on high resolution file timestamps:

  setFdTimesHiRes :: Fd -> POSIXTime -> POSIXTime -> IO ()
  setFileTimesHiRes :: FilePath -> POSIXTime -> POSIXTime -> IO ()
  setSymbolicLinkTimesHiRes :: FilePath -> POSIXTime -> POSIXTime -> IO ()
  touchFd :: Fd -> IO ()
  touchSymbolicLink :: FilePath -> IO ()
  

• Export SignalInfo(..) and SignalSpecificInfo(..) as well as the two Handler constructors CatchInfo and CatchInfoOnce from System.Posix.Signals

• Bundled with GHC 7.6.1
• New functions mkdtemp and mkstemps in System.Posix.Temp
• New functions setEnvironment and cleanEnv
• New functions accessTimeHiRes, modificationTimeHiRes, and statusChangeTimeHiRes for accessing high resolution timestamps
