* Update to Unicode version 7.0David Feuer2014-10-211-3468/+3817

* Refactor to avoid need for `Unicode.hs-boot`Herbert Valerio Riedel2014-10-112-10/+10
| | | | | | | | | | | This avoids the import-cycle caused by the import of `Foreign.C.Types` by using `Int` instead of `CInt` for the Unicode classification functions. This refactoring also allows to remove a couple of `fromIntegral`s. Reviewed By: rwbarton, ekmett Differential Revision: https://phabricator.haskell.org/D328

* Build fix for iOS; fixes #7759Ian Lynagh2013-04-211-1/+2
| | | | | | | | | Patch from Stephen Blackheath. The issue here is that the #defines EVFILT_READ and EVFILT_WRITE have the values -1 and -2. The original code translates that to filterRead = Filter -1 which is wrong Haskell and fails to compile. The modified code produces the correct code filterRead = Filter (-1)

* GHC.Windows: more error support (guards, system error strings)Joey Adams2012-11-171-27/+42
| | | | | | | | | | | | | | | This changes the output of throwGetLastError to include the system error message, rather than the message of our fictitious errno. It also adds several definitions to GHC.Windows, mostly from the Win32 package. The exceptions are: * getErrorMessage: returns a String, unlike in System.Win32.Types, where it returns an LPWSTR. * errCodeToIOError: new * c_maperrno_func: new

* Typeable overhaul (see #5275)Simon Marlow2011-07-111-0/+238
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instances of Typeable used to call mkTyCon: mkTyCon :: String -> TyCon which internally kept a table mapping Strings to Ints, so that each TyCon could be given a unique Int for fast comparison. This meant the String has to be unique across all types in the program. However, derived instances of typeable used the qualified original name (e.g. "GHC.Types.Int") which is not necessarily unique, is non-portable, and exposes implementation details. The String passed to mkTyCon is returned by tyConString :: TyCon -> String which let the user get at this non-portable representation (also the Show instance returns this String). Now we store three Strings in TyCon. The internal representation is this: data TyCon = TyCon { tyConHash :: {-# UNPACK #-} !Fingerprint, tyConPackage :: String, tyConModule :: String, tyConName :: String } (internal representations are now provided by Data.Typeable.Internal) The fields of TyCon are not exposed via the public API. Together the three fields tyConPackage, tyConModule and tyConName uniquely identify a TyCon, and the Fingerprint is a hash of the concatenation of these three Strings (so no more internal cache to map strings to unique Ids). tyConString now returns the value of tyConName only, so is therefore portable (but the String returned does not uniquely identify the TyCon). I've measured the performance impact of this change, and performance seems to be uniformly better. This should improve things for SYB in particular. Also, the size of the code generated for deriving Typeable is less than half as much as before. == API changes == === mkTyCon is DEPRECATED == mkTyCon is used by some hand-written instances of Typeable. It still works as before, but is deprecated in favour of... === Add mkTyCon3 === mkTyCon3 :: String -> String -> String -> TyCon mkTyCon3 takes the package, module, and name of the TyCon respectively. Most users can just derive Typeable, there's no need to use mkTyCon3. In due course we can rename mkTyCon3 back to mkTyCon. === typeRepKey changed === Previously we had typeRepKey :: TypeRep -> IO Int but since we don't assign unique Ints to TypeReps any more, this is difficult to implement. Instead we provide an abstract key type which is an instance of Eq and Ord, and internally is implemented by the fingerprint: data TypeRepKey -- abstract, instance of Eq, Ord typeRepKey :: TypeRep -> IO TypeRepKey typeRepKey is still in the IO monad, because the Ord instance is implementation-defined.
* FIX #2271Daniel Fischer2010-10-181-9/+260
| | | | | | | | | | Faster rounding functions for Double and float with Int or Integer results. Fixes #2271. Since some glibc's have buggy rintf or rint functions and the behaviour of these functions depends on the setting of the rounding mode, we provide our own implementations which always round ties to even. Also added rewrite rules and removed trailing whitespace.

* Windows: map ERROR_NO_DATA to EPIPE, rather than EINVALSimon Marlow2010-09-151-1/+4
| | | | | | | | | | | | | | | 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.

* Move file locking into the RTS, fixing #629, #1109Simon Marlow2007-11-201-112/+0
| | | | | | | | | | | | | | | File locking (of the Haskell 98 variety) was previously done using a static table with linear search, which had two problems: the array had a fixed size and was sometimes too small (#1109), and performance of lockFile/unlockFile was suboptimal due to the linear search. Also the algorithm failed to count readers as required by Haskell 98 (#629). Now it's done using a hash table (provided by the RTS). Furthermore I avoided the extra fstat() for every open file by passing the dev_t and ino_t into lockFile. This and the improvements to the locking algorithm result in a healthy 20% or so performance increase for opening/closing files (see openFile008 test).
