Log:
Partial rewrite of the POSIX library.
The main purpose of this sweep is to remove the last dependencies of
the compiler on hslibs. When I've committed the associated compiler
changes, only the 'base' package will be required to bootstrap the
compiler. Additionally to build GHCi, the 'readline' and 'unix'
packages will be required.
The new POSIX library lives mostly in libraries/unix, with a few bits
required for compiler bootstrapping in libraries/base. The 'base'
package is mostly free of hsc2hs code to make bootstrapping from HC
files easier, but the 'unix' package will use hsc2hs liberally.
The old POSIX library continues to provide more-or-less the same
interface as before, although some of the types are more correct now
(previously lots of POSIX types were just mapped to Int). The new
interface is largely the same as the old, except that some new
functionality from the latest POSIX spec has been added (eg. symbolic
links).
So far, the new POSIX library has signal support, directory/file
operations and lots of stuff from unistd.h. The module names are:
System.Posix
The main dude, exports everything
System.Posix.Types
All the POSIX types, using the same naming scheme as
Foreign.C.Types, Eg. CUid, COff, etc. Many of these types
were previously exported by GHC.Posix.
Additionally exports the "nicer" names used by the old POSIX
library for compatibility (eg. ProcessID == CPid, FileMode ==
CMode, etc.)
All reasonable instances are derived for these types.
System.Posix.Signals
Signal support, contains most of which was in PosixProcPrim before.
The RTS interface to the signal handling support has been
rationalised slightly.
System.Posix.Directory
Directory support, most were in PosixFiles before.
System.Posix.Files
File operations, most were in PosixFiles before.
System.Posix.Unistd
(for want of a better name) Miscellaneous bits that mostly come
from the unistd.h header file. PosixProcEnv before.
The rest of the library should pan out like so:
System.Posix.IO
System.Posix.Error (maybe)
System.Posix.Process
System.Posix.Terminal
(I've no doubt broken Win32 support, but I'm checking the build at the moment).
