MERGED from commit e518038a

The other .Common modules aren't expose, and we think exposing this
one was a mistake.

They broken the build on OSX. See #2979.

Based on a patch from Arnaud Degroote <degroote@NetBSD.org> in
trac #5480.

It may depend on getSlaveTerminalName if !defined(HAVE_OPENPTY)

The new module System.Posix.ByteString provides exactly the same API
as System.Posix, except that:

  - There is a new type: RawFilePath = ByteString

  - All functions mentioning FilePath in the System.Posix API
    use RawFilePath in the System.Posix.ByteString API

  - RawFilePaths are not subject to Unicode locale encoding and
    decoding, unlike FilePaths.  They are the exact bytes passed to and
    returned from the underlying POSIX API.

  - Similarly for functions that deal in environment
    strings (System.Posix.Env): these use untranslated ByteStrings
    in System.Posix.Environment

  - There is a new function

     System.Posix.ByteString.getArgs :: [ByteString]

    returning the raw untranslated arguments as passed to exec() when
    the program was started.

The RTS doesn't get a chance to produce the profile output after
executeFile, so tests that check for correct profiling output will fail.

Fixes validate on amd64/Linux with:

SRC_CC_OPTS += -Wmissing-parameter-type
SRC_CC_OPTS += -Wold-style-declaration
SRC_CC_OPTS += -Wold-style-definition

versions, for setProcessGroupID and createProcessGroup

Favonia authored 14 years ago and Simon Marlow committed 14 years ago

Make it possible to query the process group of an existing
process (through 'getProcessGroupIDOf') and try to make
function names more consistent. Here is the full list of
API changes in System.Posix.Process in this patch:

getProcessGroupID     => same
getProcessGroupIDOf   => new
createProcessGroup    => deprecated
createProcessGroupFor => new
joinProcessGroup      => same
setProcessGroupID     => deprecated
setProcessGroupIDOf   => new

Clarify behavior of "awaitSignal Nothing", export SignalSet that includes all signals reserved by RTS (#4504)
