[Windows: map ERROR_NO_DATA to EPIPE, rather than EINVAL
Simon Marlow <marlowsd@gmail.com>**20100915142618
 Ignore-this: 9023e5f0542419f225aef26cb6b1d88d
 WriteFile() returns ERROR_NO_DATA when writing to a pipe that is
 "closing", however by default the write() wrapper in the CRT maps this
 to EINVAL so we get confusing things like
 
   hPutChar: invalid argument (Invalid Argumnet)
 
 when piping the output of a Haskell program into something that closes
 the pipe early.  This was happening in the testsuite in a few place.
 
 The solution is to map ERROR_NO_DATA to EPIPE correctly, as we
 explicitly check for EPIPE on stdout (in GHC.TopHandler) so we can
 exit without an error in this case.

 As discussed on the libraries/haskell-cafe mailing lists
   http://www.haskell.org/pipermail/libraries/2010-April/013420.html
 
 This is a replacement for block/unblock in the asychronous exceptions
 API to fix a problem whereby a function could unblock asynchronous
 exceptions even if called within a blocked context.
 
 The new terminology is "mask" rather than "block" (to avoid confusion
 due to overloaded meanings of the latter).
 
 The following is the new API; the old API is deprecated but still
 available for the time being.
 
 Control.Exception
 -----------------
 
 mask  :: ((forall a. IO a -> IO a) -> IO b) -> IO b
 mask_ :: IO a -> IO a
 
 uninterruptibleMask :: ((forall a. IO a -> IO a) -> IO b) -> IO b
 uninterruptibleMask_ :: IO a -> IO 
 
 getMaskingState :: IO MaskingState
 
 data MaskingState
   = Unmasked
   | MaskedInterruptible 
   | MaskedUninterruptible
 
 
 Control.Concurrent
 ------------------
 
 forkIOUnmasked :: IO () -> IO ThreadId

 The performance bug in #3245 was caused by computing the typeRep
 once for each call of typeOf, rather than once for each dictionary
 contruction.  (Computing TypeReps is reasonably expensive, because
 of the hash-consing machinery.)
 
 This is readily fixed by putting the TypeRep construction outside
 the lambda.  (Arguably GHC might have worked that out itself,
 but it involves floating something between a type lambda and a
 value lambda, which GHC doesn't currently do. If it happens a lot
 we could fix that.)

 GHC.Conc.  We were already using this trick for signal handlers, I
 should have realised before.

[Make hGetContents throw an exception if an error is encountered
Simon Marlow <marlowsd@gmail.com>**20091012152955
 Ignore-this: 9f7a7176193eab25c9daaacd9261f2de
 
 Strictly speaking this breaks Haskell 98 compatibility, which requires
 hGetContents to just end the lazy stream silently if an error is
 encountered.  However, for a few reasons we think it will make
 everyone's life a bit easier if we make this change
 
  1. Errors will be a lot more common in GHC 6.12.1, in the form
     of Unicode decoding errors.
 
  2. When Haskell 98 was designed, we didn't know how to throw
     exceptions from inside lazy I/O, but now we do.
 
  3. If anyone is actually relying on the previous behaviour, their
     code is arguably broken.

 The following functions

     (<*) :: Applicative f => f a -> f b -> f a
     some :: Alternative f => f a -> f [a]
     many :: Alternative f => f a -> f [a]
 
 are moved into the corresponding classes, with the existing implementations
 as default definitions.  This gives people creating instances the option of
 defining specialized implementations of these functions, though they should
 be equivalent to the default definitions.
 
 Although (<$) is now a method of the Functor class, it is hidden in the
 re-export by the Prelude, Control.Monad and Monad.  The new module
 Data.Functor exposes the full class, plus the function (<$>).  These are
 also re-exported by Control.Applicative.

 We keep all of the code page tables in the module
 GHC.IO.Encoding.CodePage.Table.  That file was generated automatically
 by running codepages/MakeTable.hs; more details are in the comments at the
 start of that script.
 
 Storing the lookup tables adds about 40KB to each statically linked executable;
 this only increases the size of a "hello world" program by about 7%.
 
 Currently we do not support double-byte encodings (Chinese/Japanese/Korean), since
 including those codepages would increase the table size to 400KB.  It will be
 straightforward to implement them once the work on library DLLs is finished.
