Proposal: fix for getOpt (missing feature)

Mon Jun 25 16:23:27 EDT 2007
Proposal: to fix a missing feature in the Haskell implementation of GNU
getOpt. Currently, long option names _must_ have two dashes (e.g. --foo),
whereas this patch permits a single dash (e.g. -foo) where there is no
short option name to be confused with it (e.g. -f).
-------------- next part --------------
New patches:
[Implement the missing GetOpt feature: long options introduced by single -
Malcolm.Wallace at cs.york.ac.uk**20070625200820] {
hunk ./System/Console/GetOpt.hs 21
-Two rather obscure features are missing: The Bash 2.0 non-option hack
+One rather obscure feature is missing: The Bash 2.0 non-option hack

-it...) and the recognition of long options with a single dash
-(e.g. '-help' is recognised as '--help', as long as there is no short
-option 'h').
+it...).
+
+A previously missing feature is now implemented: the recognition of long
+options with a single dash (e.g. '-help' is recognised as '--help', as
+long as there is no short option 'h').
hunk ./System/Console/GetOpt.hs 191

+ | x `elem` short = shortOpt x xs rest optDescr
+ where short = concat [ cs | (Option cs _ _ _) <- optDescr ]
+getNext ('-': xs) rest optDescr = longOpt xs rest optDescr
}

[FIX: #724 (tee complains if used in a process started by ghc)
Simon Marlow <simonmar at microsoft.com>**20070507123537
Now, we only set O_NONBLOCK on file descriptors that we create
ourselves. File descriptors that we inherit (stdin, stdout, stderr)
are kept in blocking mode. The way we deal with this differs between
the threaded and non-threaded runtimes:
- with -threaded, we just make a safe foreign call to read(), which
may block, but this is ok.
- without -threaded, we test the descriptor with select() before
attempting any I/O. This isn't completely safe - someone else
might read the data between the select() and the read() - but it's
a reasonable compromise and doesn't seem to measurably affect
performance.

[Prevent duplication of unsafePerformIO on a multiprocessor
Simon Marlow <simonmar at microsoft.com>**20070306145424
Fixes #986. The idea is to add a new operation
noDuplicate :: IO ()
it is guaranteed that if two threads have executed noDuplicate, then
they are not duplicating any computation.
We now provide two new unsafe operations:
unsafeDupablePerformIO :: IO a -> a
unsafeDupableInterleaveIO :: IO a -> IO a
which are equivalent to the old unsafePerformIO and unsafeInterleaveIO
respectively. The new versions of these functions are defined as:
unsafePerformIO m = unsafeDupablePerformIO (noDuplicate >> m)
unsafeInterleaveIO m = unsafeDupableInterleaveIO (noDuplicate >> m)

is that 'timeout N E' should behave exactly the same as E as long as E
doesn't time out. In our implementation, this means that E has the same
myThreadId it would have without the timeout wrapper. Any exception E
might throw cancels the timeout and propagates further up. It also
possible for E to receive exceptions thrown to it by another thread.

[Change the API of MArray to allow resizable arrays
Simon Marlow <simonmar at microsoft.com>**20060809100548
See #704
The MArray class doesn't currently allow a mutable array to change its
size, because of the pure function
bounds :: (HasBounds a, Ix i) => a i e -> (i,i)
This patch removes the HasBounds class, and adds
getBounds :: (MArray a e m, Ix i) => a i e -> m (i,i)
to the MArray class, and
bounds :: (IArray a e, Ix i) => a i e -> (i,i)
to the IArray class.
The reason that bounds had to be incorporated into the IArray class is
because I couldn't make DiffArray work without doing this. DiffArray
acts as a layer converting an MArray into an IArray, and there was no
way (that I could find) to define an instance of HasBounds for
DiffArray.

These versions assume the n is in the bounds of the bytestring, saving
two comparison tests. Then use them in varous places where we think this
holds. These cases need double checking (and there are a few remaining
internal uses of take / drop that might be possible to convert).

* Generalise the type of unfoldrN
The type of unfoldrN was overly constrained:
unfoldrN :: Int -> (Word8 -> Maybe (Word8, Word8)) -> Word8 -> ByteString
if we compare that to unfoldr:
unfoldr :: (b -> Maybe (a, b)) -> b -> [a]
So we can generalise unfoldrN to this type:
unfoldrN :: Int -> (a -> Maybe (Word8, a)) -> a -> ByteString
and something similar for the .Char8 version. If people really do want to
use it a lot with Word8/Char then perhaps we should add a specialise pragma.

[Make unsafePerformIO lazy
simonpj at microsoft**20060508142507
The stricteness analyser used to have a HACK which ensured that NOINLNE things
were not strictness-analysed. The reason was unsafePerformIO. Left to itself,
the strictness analyser would discover this strictness for unsafePerformIO:
unsafePerformIO: C(U(AV))
But then consider this sub-expression
unsafePerformIO (\s -> let r = f x in
case writeIORef v r s of (# s1, _ #) ->
(# s1, r #)
The strictness analyser will now find that r is sure to be eval'd,
and may then hoist it out. This makes tests/lib/should_run/memo002
deadlock.
Solving this by making all NOINLINE things have no strictness info is overkill.
In particular, it's overkill for runST, which is perfectly respectable.
Consider
f x = runST (return x)
This should be strict in x.
So the new plan is to define unsafePerformIO using the 'lazy' combinator:
unsafePerformIO (IO m) = lazy (case m realWorld# of (# _, r #) -> r)
Remember, 'lazy' is a wired-in identity-function Id, of type a->a, which is
magically NON-STRICT, and is inlined after strictness analysis. So
unsafePerformIO will look non-strict, and that's what we want.

[RequireOrder: do not collect unrecognised options after a non-opt
Simon Marlow <simonmar at microsoft.com>**20060426121110
The documentation for RequireOrder says "no option processing after
first non-option", so it doesn't seem right that we should process the
rest of the arguments to collect the unrecognised ones. Presumably
the client wants to know about the unrecognised options up to the
first non-option, and will be using a different option parser for the
rest of the command line.
eg. before:
Prelude System.Console.GetOpt> getOpt' RequireOrder [] ["bar","--foo"]
([],["bar","--foo"],["--foo"],[])
after:
Prelude System.Console.GetOpt> getOpt' RequireOrder [] ["bar","--foo"]
