LiquidHaskell is executing it as a child process.--## Step 2: Install `liquid` via Package Manager--The `liquid` executable is provided as part of a standalone, battery-included package called `liquid-platform`.--Simply do:--    cabal install liquid-platform--We are working to put `liquid` on `stackage`.--You can designate a specific version of LiquidHaskell to ensure that the correct-GHC version is in the environment. As an example,--    cabal install liquid-platform-0.9.0.0--## Step 2: Install `liquid` from Source--If you want the most recent version, you can build from source as follows,-either using `stack` (recommended) or `cabal`. In either case: *recursively*-clone the repo and then build:--### Build with `stack` and `Nix`--This doesn't require to install `stack` or `z3` in advance.

Therefore, you might need to extend your `$GHC_PACKAGE_PATH` to-have it point to the right location(s). Typically the easiest way is to call `stack path`, which will-print a lot of diagnostic output. From that it should be suffient to copy the paths printed as part of-`ghc-package-path: <some-paths>` and extend the `GHC_PACKAGE_PATH` this way -(typically editing your `.bashrc` to make the changes permanent):--```-export GHC_PACKAGE_PATH=$GHC_PACKAGE_PATH:<some-paths>-```--After that, running `liquid` anywhere from the filesystem should work.---## Troubleshooting---1. If you're on Windows, please make sure the SMT solver is installed-    in the **same** directory as LiquidHaskell itself (i.e. wherever-    `cabal` or `stack` puts your binaries). That is, do:--    ```-    which liquid-    ```--    and make sure that `z3` or `cvc4` or `mathsat` are in the `PATH`-    returned by the above.--2. If you installed via `stack` and are experiencing path related woes, try:--    ```-    stack exec -- liquid path/to/file.hs-    ```--[nix]: https://nixos.org/download.html-[stack]: https://github.com/commercialhaskell/stack/blob/master/doc/install_and_upgrade.md

− MIRRORING_MODULES.md 
@@ -1,62 +0,0 @@--## Mirroring modules for the liquid ecosystem--We provide a fairly simple tool (under the form of an Haskell executable) to make the process of-generating "mirror modules" easy. This need might arise when developing new packages containing only refinemnents-for existing packages. These modules are usually meant to be considered \"drop in\", which means they should-expose the very same modules the original package provided. For big and rich packages, this process can be-tedious to do by hand, especially if only a handful of modules contains refinemnents. This is where this-tool comes in hand.--The tool for now can be built only if the `mirror-modules-helper` flag is passed -(and it's **not** turned on by default) to avoid pulling unnecessary dependencies when we build-the `liquidhaskell` library. We can in principle move this into a standalone package, in the future.--### Installation instructions (stack)--```-stack build --flag liquidhaskell:mirror-modules-helper-```--### Usage--The tool accepts the following options:--```-stack exec mirror-modules -- --help--Usage: mirror-modules [--unsafe-override-files] (-l|--modules-list ARG)-                      (-p|--mirror-package-name ARG) (-i|--target ARG)-  Create modules to be used in mirror packages.--Available options:-  --unsafe-override-files  Overrides an Haskell module if already present in the-                           folder.-  -l,--modules-list ARG    The path to a file containing a newline-separated-                           list of modules to mirror.-  -p,--mirror-package-name ARG-                           The name of the mirror package we are targeting.-                           (example: liquid-foo)-  -i,--target ARG          The path to the root of the module hierarchy for the-                           target package. (example: liquid-foo/src)-  -h,--help                Show this help text-```---The tool is faily simple and eschew more sophisticated mechanisms (like automatically pulling the mirrored-package from Hackage and extract the exposed-modules from the parsed Cabal manifest), so it accepts a file-with the full list of exposed modules of the mirrored package (which can be copied and pasted from the Cabal-manifest directly) and it's smart enough to figure out which modules needs mirroring. The user can decide-to unsafely override existing modules by passing the `--unsafe-override-files` option as input.-Last but not least, we require the name of the mirror package (e.g. `liquid-foo`) as well as the path-(relative or absolute) where the source files are (e.g. `liquid-foo/src`).--### Example (liquid-base)--For example, this is how we can mirror all the packages from `base` into `liquid-base`:--```-stack exec mirror-modules -- -l ../packages.txt -p liquid-base -i liquid-base/src/-```--Where `packages.txt` contains the newline-separated list of all the `exposed-modules` from `base`.

[Int<p>] -> Int<p>-```--can just be written as--```haskell-  foo :: forall <p :: {Int}>. [p] -> p-```--where we need not write `Int<p>`, its enough to just write `p`.--#### Step 2: An explicit "Meet" Operator--However, sometimes you need to write things like:--```haskell-  List <p> a <<p>>-```--where `p :: List a -> Bool` i.e. `p :: {List a}` and which denotes--* a list-of-a that is recursively indexed by `p`, AND-* where the top-level list is constrained by `p`.--That is, more generally, where you want to--* additionally, index the type with other abstract refinements, AND-* "apply" an abstract refinement to the "top-level" type.--For this, I think we should have an explicit *meet* operator-Note that, earlier `Int<p>` was an *implicit* meet operator,-where we were *conjoining* `Int` and `p`. Viewing `p` as-just being a refined `Int` allows us to SEPARATE "meet"-to only those places where its really needed.--So we can write the funny `List <p> a <<p>>` as:--```haskell-  p /\ List <p> a-```--See below for many other examples:--#### Example: Value Dependencies--**Old**--```haskell-  foo :: forall <p :: Int -> Int -> Bool>. x:Int -> [Int<p x>] -> Int<p x>-```--**New**--```haskell-  foo :: forall <p :: Int -> {Int}>. x:Int -> [p x] -> p x-```--#### Example: Dependent Pairs--**Old**--```haskell-  data Pair a b <p :: a -> b -> Bool>-    = Pair { pairX :: a-           , pairB :: b<p pairX>-           }--  type OrdPair a = Pair <{\px py -> px < py}> a a-```--**New**--```haskell-  data Pair a b <p :: a -> {b}>-    = Pair { pairX :: a-           , pairY :: p pairX-           }---  type OrdPair a = Pair a a <\px ->  {py:a | px < py}>-```--#### Example: Binary Search Maps--**Old**--```haskell-  data Map k a <l :: root:k -> k -> Bool, r :: root:k -> k -> Bool>-      = Tip-      | Bin { mSz    :: Size-            , mKey   :: k-            , mValue :: a-            , mLeft  :: Map <l, r> (k <l mKey>) a-            , mRight :: Map <l, r> (k <r mKey>) a }--  type OMap k a = Map <{\root v -> v < root }, {\root v -> v > root}> k a-```--**New**--```haskell-  data Map k a <l :: root:k -> {k}, r :: root:k -> {k}>-      = Tip-      | Bin { mSz    :: Size-            , mKey   :: k-            , mValue :: a-            , mLeft  :: Map (l mKey) a <l, r>-            , mRight :: Map (r mKey) a <l, r> }--  type OMap k a = Map k a <\root -> {v:k | v < root }, \root -> {v:k | root < v}>-```--#### Example: Ordered Lists--**Old**--```haskell-  data List a <p :: a -> a -> Bool>-    = Emp-    | Cons { lHd :: a-           , lTl :: List <p> (a<p lHd>)-           }--  type OList a = List <{\x v -> x <= v}> a-```--**New**--```haskell-  data List a <p :: a -> {a}>-    = Emp-    | Cons { lHd :: a-           , lTl :: List (p lHd) <p>-           }--  type OList a = List a <\x -> {v:a | x <= v}>-```--#### Example: Infinite Streams--**Old**--```haskell-  data List a <p :: List a -> Prop>-    = N-    | C { x  :: a-        , xs :: List <p> a <<p>>-        }--  type Stream a = {xs: List <{\v -> isCons v}> a | isCons xs}-```--**New**--```haskell-  data List a <p :: {List a}>-    = N-    | C { x  :: a-        , xs :: p /\ List a <p>-        }--  type Stream a = {xs: List a <{v | isCons v}> | isCons xs}-```-----### Old Proposal---|                      | Current Syntax                | Future Syntax                 |-|----------------------|-------------------------------|-------------------------------|-| Abstract Refinements | `List <{\x v -> v >= x}> Int` | `List Int (\x v -> v >= x)`   |-|                      | `[a<p>]<{\x v -> v >= x}>`    | `[a p] (\x v -> v >= x) (??)` |-|                      | `Int<p>`                      | `Int p`                       |-|                      | `Int<\x -> x >=0>`            | `Int (\x -> x >= 0)`          |--|                      | `Maybe <<p>> (a<q>) (?)`      | `Maybe (a q) p`               |-|                      | `Map <l, r> <<p>> k v  (?)`   | `Maybe k v l r p`             |--| Type Arguments       | `ListN a {len xs + len ys}`   | `ListN a (len xs + len ys)`   |--Q: How do I distinguish `Int p` with `ListN a n`?-(`p` is a abstract refinement and `n` is an `Integer`)--A: From the context!-Use simple kinds, i.e.-`ListN :: * -> Int -> *`-`Int :: ?AR -> *`

However, note that--   type Parser a = [Char] -> (a, [Char])--roughly speaking, and here `eats` is actually the DIFFERENCE of the lengths of-the input and output [Char] ... so I'm not sure how exactly we would reason about-the IMPLEMENTATION of `eats` but certainly we should be able to USE it in clients-of parsec.--Note that you need a refinement ON the function type, the idea being that:--1. the BODY of a recursive function is checked in the termination-strengthened-environment that constrains the function to satisfy the predicate `rec`--2. whenever you use >>= on a recursive function, the PRECEDING action must have-consumed some tokens.--3. the number of tokens consumed by the combined action equals the sum of the two-actions (all the business about exists z and Q is to allow us to depend on the output-value of `f` (c.f. tests/pos/cont1.hs)---PROJECT: HTT style ST/IO reasoning with Abstract Refinements---------------------------------------------------------------+ Create a test case: `tests/todo/Eff*.hs`--+ Introduce a new sort of refinement `Ref` (with alias `RTProp`)-   + Types.hs: Add to `Ref` -- in addition to `RMono` [---> `RPropP`] and `RPoly` [---> `RProp`]-   + Types.hs: Add a `World t` for SL formulas...---+ Allow `PVar` to have the sort `HProp`-   + CHANGE `ptype :: PVKind t` where `data PVKind t = PVProp t | PVHProp`-   + Can we reuse `RAllP` to encode `HProp`-quantification?

This is doable with a-pre-pass that generates and solves `HProp` constraints as follows:--1. At each instantiation, make up _fresh_ variables `h`-2. Treat _bound_ heap-variables as **constants**-3.

There's no reason for this, but its tedious to have to make up-new heap binders and what not. Clutters stuff. This is _slightly_-problematic.

Solution is slightly-clunky: rather than the _implicit_ heap binder, add an explicit pure parameter:--```haskell-incr :: p:IORef Int -> i:Int -> IO {v:Int| v = i} <p |-> {v = i}, p |-> {v = i + 1}>-```--**Q3.** How to relate `Post`-condition to the `Pre`-conditions?--Note that the `Post`-condition is a unary predicate -- i.e. _does not_-refer to the input world.

Not-really. Just write signatures like:--    read :: IORef a -> IO a--aha, but there's a problem: the `a` is too _coarse_ or flow-insensitive: it-holds a supertype of all the values written at the location, as opposed to the-_current_ value.

While the bound thread is still scheduled by the Haskell run-time-system, the operating system thread takes care of all the foreign calls made-by the bound thread.--To a foreign library, the bound thread will look exactly like an ordinary-operating system thread created using OS functions like @pthread_create@-or @CreateThread@.--Bound threads can be created using the 'forkOS' function below. All foreign-exported functions are run in a bound thread (bound to the OS thread that-called the function). Also, the @main@ action of every Haskell program is-run in a bound thread.--Why do we need this? Because if a foreign library is called from a thread-created using 'forkIO', it won't have access to any /thread-local state/ - -state variables that have specific values for each OS thread-(see POSIX's @pthread_key_create@ or Win32's @TlsAlloc@). Therefore, some-libraries (OpenGL, for example) will not work from a thread created using-'forkIO'. They work fine in threads created using 'forkOS' or when called-from @main@ or from a @foreign export@.--In terms of performance, 'forkOS' (aka bound) threads are much more-expensive than 'forkIO' (aka unbound) threads, because a 'forkOS'-thread is tied to a particular OS thread, whereas a 'forkIO' thread-can be run by any OS thread.  Context-switching between a 'forkOS'-thread and a 'forkIO' thread is many times more expensive than between-two 'forkIO' threads.--Note in particular that the main program thread (the thread running-@Main.main@) is always a bound thread, so for good concurrency-performance you should ensure that the main thread is not doing-repeated communication with other threads in the system.  Typically-this means forking subthreads to do the work using 'forkIO', and-waiting for the results in the main thread.---}---- | 'True' if bound threads are supported.--- If @rtsSupportsBoundThreads@ is 'False', 'isCurrentThreadBound'--- will always return 'False' and both 'forkOS' and 'runInBoundThread' will--- fail.-foreign import ccall rtsSupportsBoundThreads :: Bool---{- | -Like 'forkIO', this sparks off a new thread to run the 'IO'-computation passed as the first argument, and returns the 'ThreadId'-of the newly created thread.--However, 'forkOS' creates a /bound/ thread, which is necessary if you-need to call foreign (non-Haskell) libraries that make use of-thread-local state, such as OpenGL (see "Control.Concurrent#boundthreads").--Using 'forkOS' instead of 'forkIO' makes no difference at all to the-scheduling behaviour of the Haskell runtime system.  It is a common-misconception that you need to use 'forkOS' instead of 'forkIO' to-avoid blocking all the Haskell threads when making a foreign call;-this isn't the case.  To allow foreign calls to be made without-blocking all the Haskell threads (with GHC), it is only necessary to-use the @-threaded@ option when linking your program, and to make sure-the foreign import is not marked @unsafe@.--}--forkOS :: IO () -> IO ThreadId--foreign export ccall forkOS_entry-    :: StablePtr (IO ()) -> IO ()--foreign import ccall "forkOS_entry" forkOS_entry_reimported-    :: StablePtr (IO ()) -> IO ()--forkOS_entry :: StablePtr (IO ()) -> IO ()-forkOS_entry stableAction = do-        action <- deRefStablePtr stableAction-        action--foreign import ccall forkOS_createThread-    :: StablePtr (IO ()) -> IO CInt--failNonThreaded :: IO a-failNonThreaded = fail $ "RTS doesn't support multiple OS threads "-                       ++"(use ghc -threaded when linking)"--forkOS action0-    | rtsSupportsBoundThreads = do-        mv <- newEmptyMVar-        b <- Exception.getMaskingState-        let-            -- async exceptions are masked in the child if they are masked-            -- in the parent, as for forkIO (see #1048). forkOS_createThread-            -- creates a thread with exceptions masked by default.-            action1 = case b of-                        Unmasked -> unsafeUnmask action0-                        MaskedInterruptible -> action0-                        MaskedUninterruptible -> uninterruptibleMask_ action0--            action_plus = Exception.catch action1 childHandler--        entry <- newStablePtr (myThreadId >>= putMVar mv >> action_plus)-        err <- forkOS_createThread entry-        when (err /= 0) $ fail "Cannot create OS thread."-        tid <- takeMVar mv-        freeStablePtr entry-        return tid-    | otherwise = failNonThreaded---- | Returns 'True' if the calling thread is /bound/, that is, if it is--- safe to use foreign libraries that rely on thread-local state from the--- calling thread.-isCurrentThreadBound :: IO Bool-isCurrentThreadBound = IO $ \ s# ->-    case isCurrentThreadBound# s# of-        (# s2#, flg #) -> (# s2#, not (flg ==# 0#) #)---{- | -Run the 'IO' computation passed as the first argument.

Typically Haskell-      threads are an order of magnitude or two more efficient (in-      terms of both time and space) than operating system threads.--      The downside of having lightweight threads is that only one can-      run at a time, so if one thread blocks in a foreign call, for-      example, the other threads cannot continue.  The GHC runtime-      works around this by making use of full OS threads where-      necessary.  When the program is built with the @-threaded@-      option (to link against the multithreaded version of the-      runtime), a thread making a @safe@ foreign call will not block-      the other threads in the system; another OS thread will take-      over running Haskell threads until the original call returns.-      The runtime maintains a pool of these /worker/ threads so that-      multiple Haskell threads can be involved in external calls-      simultaneously.--      The "System.IO" library manages multiplexing in its own way.  On-      Windows systems it uses @safe@ foreign calls to ensure that-      threads doing I\/O operations don't block the whole runtime,-      whereas on Unix systems all the currently blocked I\/O requests-      are managed by a single thread (the /IO manager thread/) using-      a mechanism such as @epoll@ or @kqueue@, depending on what is-      provided by the host operating system.--      The runtime will run a Haskell thread using any of the available-      worker OS threads.  If you need control over which particular OS-      thread is used to run a given Haskell thread, perhaps because-      you need to call a foreign library that uses OS-thread-local-      state, then you need bound threads (see "Control.Concurrent#boundthreads").--      If you don't use the @-threaded@ option, then the runtime does-      not make use of multiple OS threads.  Foreign calls will block-      all other running Haskell threads until the call returns.  The-      "System.IO" library still does multiplexing, so there can be multiple-      threads doing I\/O, and this is handled internally by the runtime using-      @select@.--}--{- $termination--      In a standalone GHC program, only the main thread is-      required to terminate in order for the process to terminate.-      Thus all other forked threads will simply terminate at the same-      time as the main thread (the terminology for this kind of-      behaviour is \"daemonic threads\").--      If you want the program to wait for child threads to-      finish before exiting, you need to program this yourself.  A-      simple mechanism is to have each child thread write to an-      'MVar' when it completes, and have the main-      thread wait on all the 'MVar's before-      exiting:-->   myForkIO :: IO () -> IO (MVar ())->   myForkIO io = do->     mvar <- newEmptyMVar->     forkIO (io `finally` putMVar mvar ())->     return mvar--      Note that we use 'finally' from the-      "Control.Exception" module to make sure that the-      'MVar' is written to even if the thread dies or-      is killed for some reason.--      A better method is to keep a global list of all child-      threads which we should wait for at the end of the program:-->    children :: MVar [MVar ()]->    children = unsafePerformIO (newMVar [])->    ->    waitForChildren :: IO ()->    waitForChildren = do->      cs <- takeMVar children->      case cs of->        []   -> return ()->        m:ms -> do->           putMVar children ms->           takeMVar m->           waitForChildren->->    forkChild :: IO () -> IO ThreadId->    forkChild io = do->        mvar <- newEmptyMVar->        childs <- takeMVar children->        putMVar children (mvar:childs)->        forkIO (io `finally` putMVar mvar ())->->     main =->       later waitForChildren $->       ...--      The main thread principle also applies to calls to Haskell from-      outside, using @foreign export@.  When the @foreign export@ed-      function is invoked, it starts a new main thread, and it returns-      when this main thread terminates.  If the call causes new-      threads to be forked, they may remain in the system after the-      @foreign export@ed function has returned.--}--{- $preemption--      GHC implements pre-emptive multitasking: the execution of-      threads are interleaved in a random fashion.  More specifically,-      a thread may be pre-empted whenever it allocates some memory,-      which unfortunately means that tight loops which do no-      allocation tend to lock out other threads (this only seems to-      happen with pathological benchmark-style code, however).--      The rescheduling timer runs on a 20ms granularity by-      default, but this may be altered using the-      @-i\<n\>@ RTS option.  After a rescheduling-      \"tick\" the running thread is pre-empted as soon as-      possible.--      One final note: the-      @aaaa@ @bbbb@ example may not-      work too well on GHC (see Scheduling, above), due-      to the locking on a 'System.IO.Handle'.  Only one thread-      may hold the lock on a 'System.IO.Handle' at any one-      time, so if a reschedule happens while a thread is holding the-      lock, the other thread won't be able to run.  The upshot is that-      the switch from @aaaa@ to-      @bbbbb@ happens infrequently.  It can be-      improved by lowering the reschedule tick period.  We also have a-      patch that causes a reschedule whenever a thread waiting on a-      lock is woken up, but haven't found it to be useful for anything-      other than this example :-)--}-#endif /* __GLASGOW_HASKELL__ */

It has two fundamental operations: 'putMVar'--- which fills an 'MVar' if it is empty and blocks otherwise, and--- 'takeMVar' which empties an 'MVar' if it is full and blocks--- otherwise.  They can be used in multiple different ways:------  1. As synchronized mutable variables,---  2. As channels, with 'takeMVar' and 'putMVar' as receive and send, and---  3. As a binary semaphore @'MVar' ()@, with 'takeMVar' and 'putMVar' as---     wait and signal.------ They were introduced in the paper "Concurrent Haskell" by Simon--- Peyton Jones, Andrew Gordon and Sigbjorn Finne, though some details--- of their implementation have since then changed (in particular, a--- put on a full MVar used to error, but now merely blocks.)------ * Applicability------ 'MVar's offer more flexibility than 'IORef's, but less flexibility--- than 'STM'.  They are appropriate for building synchronization--- primitives and performing simple interthread communication; however--- they are very simple and susceptible to race conditions, deadlocks or--- uncaught exceptions.  Do not use them if you need perform larger--- atomic operations such as reading from multiple variables: use 'STM'--- instead.------ In particular, the "bigger" functions in this module ('readMVar',--- 'swapMVar', 'withMVar', 'modifyMVar_' and 'modifyMVar') are simply--- the composition of a 'takeMVar' followed by a 'putMVar' with--- exception safety.--- These only have atomicity guarantees if all other threads--- perform a 'takeMVar' before a 'putMVar' as well;  otherwise, they may--- block.------ * Fairness------ No thread can be blocked indefinitely on an 'MVar' unless another--- thread holds that 'MVar' indefinitely.  One usual implementation of--- this fairness guarantee is that threads blocked on an 'MVar' are--- served in a first-in-first-out fashion, but this is not guaranteed--- in the semantics.------ * Gotchas------ Like many other Haskell data structures, 'MVar's are lazy.  This--- means that if you place an expensive unevaluated thunk inside an--- 'MVar', it will be evaluated by the thread that consumes it, not the--- thread that produced it.  Be sure to 'evaluate' values to be placed--- in an 'MVar' to the appropriate normal form, or utilize a strict--- MVar provided by the strict-concurrency package.------ * Ordering------ 'MVar' operations are always observed to take place in the order--- they are written in the program, regardless of the memory model of--- the underlying machine.  This is in contrast to 'IORef' operations--- which may appear out-of-order to another thread in some cases.------ * Example------ Consider the following concurrent data structure, a skip channel.--- This is a channel for an intermittent source of high bandwidth--- information (for example, mouse movement events.)  Writing to the--- channel never blocks, and reading from the channel only returns the--- most recent value, or blocks if there are no new values.  Multiple--- readers are supported with a @dupSkipChan@ operation.------ A skip channel is a pair of 'MVar's. The first 'MVar' contains the--- current value, and a list of semaphores that need to be notified--- when it changes. The second 'MVar' is a semaphore for this particular--- reader: it is full if there is a value in the channel that this--- reader has not read yet, and empty otherwise.------ @---     data SkipChan a = SkipChan (MVar (a, [MVar ()])) (MVar ())------     newSkipChan :: IO (SkipChan a)---     newSkipChan = do---         sem <- newEmptyMVar---         main <- newMVar (undefined, [sem])---         return (SkipChan main sem)------     putSkipChan :: SkipChan a -> a -> IO ()---     putSkipChan (SkipChan main _) v = do---         (_, sems) <- takeMVar main---         putMVar main (v, [])---         mapM_ (\sem -> putMVar sem ()) sems------     getSkipChan :: SkipChan a -> IO a---     getSkipChan (SkipChan main sem) = do---         takeMVar sem---         (v, sems) <- takeMVar main---         putMVar main (v, sem:sems)---         return v------     dupSkipChan :: SkipChan a -> IO (SkipChan a)---     dupSkipChan (SkipChan main _) = do---         sem <- newEmptyMVar---         (v, sems) <- takeMVar main---         putMVar main (v, sem:sems)---         return (SkipChan main sem)--- @------ This example was adapted from the original Concurrent Haskell paper.--- For more examples of 'MVar's being used to build higher-level--- synchronization primitives, see 'Control.Concurrent.Chan' and--- 'Control.Concurrent.QSem'.-----------------------------------------------------------------------------------module Control.Concurrent.MVar-        (-          -- * @MVar@s-          MVar          -- abstract-        , newEmptyMVar  -- :: IO (MVar a)-        , newMVar       -- :: a -> IO (MVar a)-        , takeMVar      -- :: MVar a -> IO a-        , putMVar       -- :: MVar a -> a -> IO ()-        , readMVar      -- :: MVar a -> IO a-        , swapMVar      -- :: MVar a -> a -> IO a-        , tryTakeMVar   -- :: MVar a -> IO (Maybe a)-        , tryPutMVar    -- :: MVar a -> a -> IO Bool-        , isEmptyMVar   -- :: MVar a -> IO Bool-        , withMVar      -- :: MVar a -> (a -> IO b) -> IO b-        , modifyMVar_   -- :: MVar a -> (a -> IO a) -> IO ()-        , modifyMVar    -- :: MVar a -> (a -> IO (a,b)) -> IO b-#ifndef __HUGS__-        , addMVarFinalizer -- :: MVar a -> IO () -> IO ()-#endif-    ) where--#ifdef __HUGS__-import Hugs.ConcBase ( MVar, newEmptyMVar, newMVar, takeMVar, putMVar,-                  tryTakeMVar, tryPutMVar, isEmptyMVar,-                )-#endif--#ifdef __GLASGOW_HASKELL__-import GHC.MVar ( MVar, newEmptyMVar, newMVar, takeMVar, putMVar,-                  tryTakeMVar, tryPutMVar, isEmptyMVar, addMVarFinalizer-                )-#endif--#ifdef __GLASGOW_HASKELL__-import GHC.Base-#else-import Prelude-#endif--import Control.Exception.Base--{-|-  This is a combination of 'takeMVar' and 'putMVar'; ie. it takes the value-  from the 'MVar', puts it back, and also returns it.

Exception e => Handler (e -> IO a)--{- |-Sometimes you want to catch two different sorts of exception. You could-do something like--> f = expr `catch` \ (ex :: ArithException) -> handleArith ex->          `catch` \ (ex :: IOException)    -> handleIO    ex--However, there are a couple of problems with this approach. The first is-that having two exception handlers is inefficient. However, the more-serious issue is that the second exception handler will catch exceptions-in the first, e.g. in the example above, if @handleArith@ throws an-@IOException@ then the second exception handler will catch it.--Instead, we provide a function 'catches', which would be used thus:--> f = expr `catches` [Handler (\ (ex :: ArithException) -> handleArith ex),->                     Handler (\ (ex :: IOException)    -> handleIO    ex)]--}-catches :: IO a -> [Handler a] -> IO a-catches io handlers = io `catch` catchesHandler handlers--catchesHandler :: [Handler a] -> SomeException -> IO a-catchesHandler handlers e = foldr tryHandler (throw e) handlers-    where tryHandler (Handler handler) res-              = case fromException e of-                Just e' -> handler e'-                Nothing -> res---- -------------------------------------------------------------------------------- Catching exceptions--{- $catching--There are several functions for catching and examining-exceptions; all of them may only be used from within the-'IO' monad.--Here's a rule of thumb for deciding which catch-style function to-use:-- * If you want to do some cleanup in the event that an exception-   is raised, use 'finally', 'bracket' or 'onException'.-- * To recover after an exception and do something else, the best-   choice is to use one of the 'try' family.-- * ... unless you are recovering from an asynchronous exception, in which-   case use 'catch' or 'catchJust'.--The difference between using 'try' and 'catch' for recovery is that in-'catch' the handler is inside an implicit 'block' (see \"Asynchronous-Exceptions\") which is important when catching asynchronous-exceptions, but when catching other kinds of exception it is-unnecessary.  Furthermore it is possible to accidentally stay inside-the implicit 'block' by tail-calling rather than returning from the-handler, which is why we recommend using 'try' rather than 'catch' for-ordinary exception recovery.--A typical use of 'tryJust' for recovery looks like this:-->  do r <- tryJust (guard . isDoesNotExistError) $ getEnv "HOME"->     case r of->       Left  e    -> ...->       Right home -> ...---}---- -------------------------------------------------------------------------------- Asynchronous exceptions---- | When invoked inside 'mask', this function allows a blocked--- asynchronous exception to be raised, if one exists.  It is--- equivalent to performing an interruptible operation (see--- #interruptible#), but does not involve any actual blocking.------ When called outside 'mask', or inside 'uninterruptibleMask', this--- function has no effect.-allowInterrupt :: IO ()-allowInterrupt = unsafeUnmask $ return ()--{- $async-- #AsynchronousExceptions# Asynchronous exceptions are so-called because they arise due to-external influences, and can be raised at any point during execution.-'StackOverflow' and 'HeapOverflow' are two examples of-system-generated asynchronous exceptions.--The primary source of asynchronous exceptions, however, is-'throwTo':-->  throwTo :: ThreadId -> Exception -> IO ()--'throwTo' (also 'Control.Concurrent.killThread') allows one-running thread to raise an arbitrary exception in another thread.  The-exception is therefore asynchronous with respect to the target thread,-which could be doing anything at the time it receives the exception.-Great care should be taken with asynchronous exceptions; it is all too-easy to introduce race conditions by the over zealous use of-'throwTo'.--}--{- $block_handler-There\'s an implied 'mask' around every exception handler in a call-to one of the 'catch' family of functions.  This is because that is-what you want most of the time - it eliminates a common race condition-in starting an exception handler, because there may be no exception-handler on the stack to handle another exception if one arrives-immediately.  If asynchronous exceptions are masked on entering the-handler, though, we have time to install a new exception handler-before being interrupted.  If this weren\'t the default, one would have-to write something like-->      mask $ \restore ->->           catch (restore (...))->                 (\e -> handler)--If you need to unblock asynchronous exceptions again in the exception-handler, 'restore' can be used there too.--Note that 'try' and friends /do not/ have a similar default, because-there is no exception handler in this case.  Don't use 'try' for-recovering from an asynchronous exception.--}--{- $interruptible-- #interruptible#-Some operations are /interruptible/, which means that they can receive-asynchronous exceptions even in the scope of a 'mask'.  Any function-which may itself block is defined as interruptible; this includes-'Control.Concurrent.MVar.takeMVar'-(but not 'Control.Concurrent.MVar.tryTakeMVar'),-and most operations which perform-some I\/O with the outside world.  The reason for having-interruptible operations is so that we can write things like-->      mask $ \restore -> do->         a <- takeMVar m->         catch (restore (...))->               (\e -> ...)--if the 'Control.Concurrent.MVar.takeMVar' was not interruptible,-then this particular-combination could lead to deadlock, because the thread itself would be-blocked in a state where it can\'t receive any asynchronous exceptions.-With 'Control.Concurrent.MVar.takeMVar' interruptible, however, we can be-safe in the knowledge that the thread can receive exceptions right up-until the point when the 'Control.Concurrent.MVar.takeMVar' succeeds.-Similar arguments apply for other interruptible operations like-'System.IO.openFile'.--It is useful to think of 'mask' not as a way to completely prevent-asynchronous exceptions, but as a way to switch from asynchronous mode-to polling mode.  The main difficulty with asynchronous-exceptions is that they normally can occur anywhere, but within a-'mask' an asynchronous exception is only raised by operations that are-interruptible (or call other interruptible operations).  In many cases-these operations may themselves raise exceptions, such as I\/O errors,-so the caller will usually be prepared to handle exceptions arising from the-operation anyway.  To perfom an explicit poll for asynchronous exceptions-inside 'mask', use 'allowInterrupt'.--Sometimes it is too onerous to handle exceptions in the middle of a-critical piece of stateful code.  There are three ways to handle this-kind of situation:-- * Use STM.  Since a transaction is always either completely executed-   or not at all, transactions are a good way to maintain invariants-   over state in the presence of asynchronous (and indeed synchronous)-   exceptions.-- * Use 'mask', and avoid interruptible operations.  In order to do-   this, we have to know which operations are interruptible.  It is-   impossible to know for any given library function whether it might-   invoke an interruptible operation internally; so instead we give a-   list of guaranteed-not-to-be-interruptible operations below.-- * Use 'uninterruptibleMask'.  This is generally not recommended,-   unless you can guarantee that any interruptible operations invoked-   during the scope of 'uninterruptibleMask' can only ever block for-   a short time.  Otherwise, 'uninterruptibleMask' is a good way to-   make your program deadlock and be unresponsive to user interrupts.--The following operations are guaranteed not to be interruptible:-- * operations on 'IORef' from "Data.IORef"- * STM transactions that do not use 'retry'- * everything from the @Foreign@ modules- * everything from @Control.Exception@- * @tryTakeMVar@, @tryPutMVar@, @isEmptyMVar@- * @takeMVar@ if the @MVar@ is definitely full, and conversely @putMVar@ if the @MVar@ is definitely empty- * @newEmptyMVar@, @newMVar@- * @forkIO@, @forkIOUnmasked@, @myThreadId@---}--{- $catchall--It is possible to catch all exceptions, by using the type 'SomeException':--> catch f (\e -> ... (e :: SomeException) ...)--HOWEVER, this is normally not what you want to do!--For example, suppose you want to read a file, but if it doesn't exist-then continue as if it contained \"\".  You might be tempted to just-catch all exceptions and return \"\" in the handler. However, this has-all sorts of undesirable consequences.  For example, if the user-presses control-C at just the right moment then the 'UserInterrupt'-exception will be caught, and the program will continue running under-the belief that the file contains \"\".  Similarly, if another thread-tries to kill the thread reading the file then the 'ThreadKilled'-exception will be ignored.--Instead, you should only catch exactly the exceptions that you really-want. In this case, this would likely be more specific than even-\"any IO exception\"; a permissions error would likely also want to be-handled differently. Instead, you would probably want something like:--> e <- tryJust (guard . isDoesNotExistError) (readFile f)-> let str = either (const "") id e--There are occassions when you really do need to catch any sort of-exception. However, in most cases this is just so you can do some-cleaning up; you aren't actually interested in the exception itself.-For example, if you open a file then you want to close it again,-whether processing the file executes normally or throws an exception.-However, in these cases you can use functions like 'bracket', 'finally'-and 'onException', which never actually pass you the exception, but-just call the cleanup functions at the appropriate points.--But sometimes you really do need to catch any exception, and actually-see what the exception is. One example is at the very top-level of a-program, you may wish to catch any exception, print it to a logfile or-the screen, and then exit gracefully.

It--- takes a single argument, runs it, and if an exception is raised--- the \"handler\" is executed, with the value of the exception passed as an--- argument.  Otherwise, the result is returned as normal.  For example:------ >   catch (readFile f)--- >         (\e -> do let err = show (e :: IOException)--- >                   hPutStr stderr ("Warning: Couldn't open " ++ f ++ ": " ++ err)--- >                   return "")------ Note that we have to give a type signature to @e@, or the program--- will not typecheck as the type is ambiguous. While it is possible--- to catch exceptions of any type, see the section \"Catching all--- exceptions\" (in "Control.Exception") for an explanation of the problems with doing so.------ For catching exceptions in pure (non-'IO') expressions, see the--- function 'evaluate'.------ Note that due to Haskell\'s unspecified evaluation order, an--- expression may throw one of several possible exceptions: consider--- the expression @(error \"urk\") + (1 \`div\` 0)@.  Does--- the expression throw--- @ErrorCall \"urk\"@, or @DivideByZero@?------ The answer is \"it might throw either\"; the choice is--- non-deterministic. If you are catching any type of exception then you--- might catch either. If you are calling @catch@ with type--- @IO Int -> (ArithException -> IO Int) -> IO Int@ then the handler may--- get run with @DivideByZero@ as an argument, or an @ErrorCall \"urk\"@--- exception may be propogated further up. If you call it again, you--- might get a the opposite behaviour. This is ok, because 'catch' is an--- 'IO' computation.------ Note that the "Prelude" also exports a function called--- 'Prelude.catch' with a similar type to 'Control.Exception.catch',--- except that the "Prelude" version only catches the IO and user--- families of exceptions (as required by Haskell 98).------ We recommend either hiding the "Prelude" version of 'Prelude.catch'--- when importing "Control.Exception":------ > import Prelude hiding (catch)------ or importing "Control.Exception" qualified, to avoid name-clashes:------ > import qualified Control.Exception as C------ and then using @C.catch@----#ifndef __NHC__-catch   :: Exception e-        => IO a         -- ^ The computation to run-        -> (e -> IO a)  -- ^ Handler to invoke if an exception is raised-        -> IO a-#if __GLASGOW_HASKELL__-catch = catchException-#elif __HUGS__-catch m h = Hugs.Exception.catchException m h'-  where h' e = case fromException e of-            Just e' -> h e'-            Nothing -> throwIO e-#endif-#endif---- | The function 'catchJust' is like 'catch', but it takes an extra--- argument which is an /exception predicate/, a function which--- selects which type of exceptions we\'re interested in.------ > catchJust (\e -> if isDoesNotExistErrorType (ioeGetErrorType e) then Just () else Nothing)--- >           (readFile f)--- >           (\_ -> do hPutStrLn stderr ("No such file: " ++ show f)--- >                     return "")------ Any other exceptions which are not matched by the predicate--- are re-raised, and may be caught by an enclosing--- 'catch', 'catchJust', etc.-catchJust-        :: Exception e-        => (e -> Maybe b)         -- ^ Predicate to select exceptions-        -> IO a                   -- ^ Computation to run-        -> (b -> IO a)            -- ^ Handler-        -> IO a-catchJust p a handler = catch a handler'-  where handler' e = case p e of-                        Nothing -> throwIO e-                        Just b  -> handler b---- | A version of 'catch' with the arguments swapped around; useful in--- situations where the code for the handler is shorter.

It--- takes a single argument, runs it, and if an exception is raised--- the \"handler\" is executed, with the value of the exception passed as an--- argument.

For example:------ >   catch (openFile f ReadMode) --- >       (\e -> hPutStr stderr ("Couldn't open "++f++": " ++ show e))------ For catching exceptions in pure (non-'IO') expressions, see the--- function 'evaluate'.------ Note that due to Haskell\'s unspecified evaluation order, an--- expression may return one of several possible exceptions: consider--- the expression @error \"urk\" + 1 \`div\` 0@.  Does--- 'catch' execute the handler passing--- @ErrorCall \"urk\"@, or @ArithError DivideByZero@?------ The answer is \"either\": 'catch' makes a--- non-deterministic choice about which exception to catch.  If you--- call it again, you might get a different exception back.

This primitive can-be instantiated in several ways to map over the immediate subterms-of a term; see the @gmap@ combinators later in this class.  Indeed, a-generic programmer does not necessarily need to use the ingenious gfoldl-primitive but rather the intuitive @gmap@ combinators.  The 'gfoldl'-primitive is completed by means to query top-level constructors, to-turn constructor representations into proper terms, and to list all-possible datatype constructors.  This completion allows us to serve-generic programming scenarios like read, show, equality, term generation.--The combinators 'gmapT', 'gmapQ', 'gmapM', etc are all provided with-default definitions in terms of 'gfoldl', leaving open the opportunity-to provide datatype-specific definitions.-(The inclusion of the @gmap@ combinators as members of class 'Data'-allows the programmer or the compiler to derive specialised, and maybe-more efficient code per datatype.  /Note/: 'gfoldl' is more higher-order-than the @gmap@ combinators.  This is subject to ongoing benchmarking-experiments.  It might turn out that the @gmap@ combinators will be-moved out of the class 'Data'.)--Conceptually, the definition of the @gmap@ combinators in terms of the-primitive 'gfoldl' requires the identification of the 'gfoldl' function-arguments.  Technically, we also need to identify the type constructor-@c@ for the construction of the result type from the folded term type.--In the definition of @gmapQ@/x/ combinators, we use phantom type-constructors for the @c@ in the type of 'gfoldl' because the result type-of a query does not involve the (polymorphic) type of the term argument.-In the definition of 'gmapQl' we simply use the plain constant type-constructor because 'gfoldl' is left-associative anyway and so it is-readily suited to fold a left-associative binary operation over the-immediate subterms.  In the definition of gmapQr, extra effort is-needed. We use a higher-order accumulation trick to mediate between-left-associative constructor application vs. right-associative binary-operation (e.g., @(:)@).  When the query is meant to compute a value-of type @r@, then the result type withing generic folding is @r -> r@.-So the result of folding is a function to which we finally pass the-right unit.--With the @-XDeriveDataTypeable@ option, GHC can generate instances of the-'Data' class automatically.

This is a useful property to know-when dealing with race conditions: eg. if there are two threads that-can kill each other, it is guaranteed that only one of the threads-will get to kill the other.--Whatever work the target thread was doing when the exception was-raised is not lost: the computation is suspended until required by-another thread.--If the target thread is currently making a foreign call, then the-exception will not be raised (and hence 'throwTo' will not return)-until the call has completed.  This is the case regardless of whether-the call is inside a 'mask' or not.  However, in GHC a foreign call-can be annotated as @interruptible@, in which case a 'throwTo' will-cause the RTS to attempt to cause the call to return; see the GHC-documentation for more details.--Important note: the behaviour of 'throwTo' differs from that described in-the paper \"Asynchronous exceptions in Haskell\"-(<http://research.microsoft.com/~simonpj/Papers/asynch-exns.htm>).-In the paper, 'throwTo' is non-blocking; but the library implementation adopts-a more synchronous design in which 'throwTo' does not return until the exception-is received by the target thread.  The trade-off is discussed in Section 9 of the paper.-Like any blocking operation, 'throwTo' is therefore interruptible (see Section 5.3 of-the paper).  Unlike other interruptible operations, however, 'throwTo'-is /always/ interruptible, even if it does not actually block.--There is no guarantee that the exception will be delivered promptly,-although the runtime will endeavour to ensure that arbitrary-delays don't occur.  In GHC, an exception can only be raised when a-thread reaches a /safe point/, where a safe point is where memory-allocation occurs.  Some loops do not perform any memory allocation-inside the loop and therefore cannot be interrupted by a 'throwTo'.--If the target of 'throwTo' is the calling thread, then the behaviour-is the same as 'Control.Exception.throwIO', except that the exception-is thrown as an asynchronous exception.  This means that if there is-an enclosing pure computation, which would be the case if the current-IO operation is inside 'unsafePerformIO' or 'unsafeInterleaveIO', that-computation is not permanently replaced by the exception, but is-suspended as if it had received an asynchronous exception.--Note that if 'throwTo' is called with the current thread as the-target, the exception will be thrown even if the thread is currently-inside 'mask' or 'uninterruptibleMask'.-  -}-throwTo :: Exception e => ThreadId -> e -> IO ()-throwTo (ThreadId tid) ex = IO $ \ s ->-   case (killThread# tid (toException ex) s) of s1 -> (# s1, () #)---- | Returns the 'ThreadId' of the calling thread (GHC only).-myThreadId :: IO ThreadId-myThreadId = IO $ \s ->-   case (myThreadId# s) of (# s1, tid #) -> (# s1, ThreadId tid #)----- |The 'yield' action allows (forces, in a co-operative multitasking--- implementation) a context-switch to any other currently runnable--- threads (if any), and is occasionally useful when implementing--- concurrency abstractions.-yield :: IO ()-yield = IO $ \s ->-   case (yield# s) of s1 -> (# s1, () #)--{- | 'labelThread' stores a string as identifier for this thread if-you built a RTS with debugging support.

(Reason: allowing--- this would effectively allow a transaction inside a transaction, depending--- on exactly when the thunk is evaluated.)------ However, see 'newTVarIO', which can be called inside 'unsafePerformIO',--- and which allows top-level TVars to be allocated.--atomically :: STM a -> IO a-atomically (STM m) = IO (\s -> (atomically# m) s )---- |Retry execution of the current memory transaction because it has seen--- values in TVars which mean that it should not continue (e.g. the TVars--- represent a shared buffer that is now empty).

A queue can be built from a list of--- elements, sorted by keys, in linear time.------ This implementation is due to Ralf Hinze with some modifications by--- Scott Dillard and Johan Tibell.------ * Hinze, R., /A Simple Implementation Technique for Priority Search--- Queues/, ICFP 2001, pp. 110-121------ <http://citeseer.ist.psu.edu/hinze01simple.html>-module GHC.Event.PSQ-    (-    -- * Binding Type-    Elem(..)-    , Key-    , Prio--    -- * Priority Search Queue Type-    , PSQ--    -- * Query-    , size-    , null-    , lookup--    -- * Construction-    , empty-    , singleton--    -- * Insertion-    , insert--    -- * Delete/Update-    , delete-    , adjust--    -- * Conversion-    , toList-    , toAscList-    , toDescList-    , fromList--    -- * Min-    , findMin-    , deleteMin-    , minView-    , atMost-    ) where--import Data.Maybe (Maybe(..))-import GHC.Base-import GHC.Num (Num(..))-import GHC.Show (Show(showsPrec))-import GHC.Event.Unique (Unique)---- | @E k p@ binds the key @k@ with the priority @p@.-data Elem a = E-    { key   :: {-# UNPACK #-} !Key-    , prio  :: {-# UNPACK #-} !Prio-    , value :: a-    } deriving (Eq, Show)----------------------------------------------------------------------------- | A mapping from keys @k@ to priorites @p@.--type Prio = Double-type Key = Unique--data PSQ a = Void-           | Winner {-# UNPACK #-} !(Elem a)-                    !(LTree a)-                    {-# UNPACK #-} !Key  -- max key-           deriving (Eq, Show)---- | /O(1)/ The number of elements in a queue.-size :: PSQ a -> Int-size Void            = 0-size (Winner _ lt _) = 1 + size' lt---- | /O(1)/ True if the queue is empty.-null :: PSQ a -> Bool-null Void           = True-null (Winner _ _ _) = False---- | /O(log n)/ The priority and value of a given key, or Nothing if--- the key is not bound.-lookup :: Key -> PSQ a -> Maybe (Prio, a)-lookup k q = case tourView q of-    Null -> Nothing-    Single (E k' p v)-        | k == k'   -> Just (p, v)-        | otherwise -> Nothing-    tl `Play` tr-        | k <= maxKey tl -> lookup k tl-        | otherwise      -> lookup k tr----------------------------------------------------------------------------- Construction--empty :: PSQ a-empty = Void---- | /O(1)/ Build a queue with one element.-singleton :: Key -> Prio -> a -> PSQ a-singleton k p v = Winner (E k p v) Start k----------------------------------------------------------------------------- Insertion---- | /O(log n)/ Insert a new key, priority and value in the queue.

This code was added to-the Prelude just before the 1.2 release, when Lennart, working with an-early version of hbi, noticed that (read . show) was not the identity-for floating-point numbers.  (There was a one-bit error about half the-time.)  The original version of the conversion function was in fact-simply a floating-point divide, as you suggest above. The new version-is, I grant you, somewhat denser.--Unfortunately, Joe's code doesn't work!

Furthermore, when using-'unsafePerformIO' to cause side-effects, you should take the following-precautions to ensure the side effects are performed as many times as-you expect them to be.  Note that these precautions are necessary for-GHC, but may not be sufficient, and other compilers may require-different precautions:--  * Use @{\-\# NOINLINE foo \#-\}@ as a pragma on any function @foo@-        that calls 'unsafePerformIO'.  If the call is inlined,-        the I\/O may be performed more than once.--  * Use the compiler flag @-fno-cse@ to prevent common sub-expression-        elimination being performed on the module, which might combine-        two side effects that were meant to be separate.  A good example-        is using multiple global variables (like @test@ in the example below).--  * Make sure that the either you switch off let-floating (@-fno-full-laziness@), or that the -        call to 'unsafePerformIO' cannot float outside a lambda.  For example, -        if you say:-        @-           f x = unsafePerformIO (newIORef [])-        @-        you may get only one reference cell shared between all calls to @f@.-        Better would be-        @-           f x = unsafePerformIO (newIORef [x])-        @-        because now it can't float outside the lambda.--It is less well known that-'unsafePerformIO' is not type safe.

This guarantees roundtripping because--- unicode input that includes lone surrogate codepoints is invalid by--- definition.------ When we used private-use characters there was a technical problem when it--- came to encoding back to bytes using iconv. The iconv code will not fail when--- it tries to encode a private-use character (as it would if trying to encode--- a surrogate), which means that we won't get a chance to replace it--- with the byte we originally escaped.------ To work around this, when filling the buffer to be encoded (in--- writeBlocks/withEncodedCString/newEncodedCString), we replaced the--- private-use characters with lone surrogates again! Likewise, when--- reading from a buffer (unpack/unpack_nl/peekEncodedCString) we have--- to do the inverse process.------ The user of String would never see these lone surrogates, but it--- ensures that iconv will throw an error when encountering them.

The cases that are wrong:--  * reading/writing to a blocking FD in non-threaded mode.-    In threaded mode, we just make a safe call to read().  -    In non-threaded mode we call select() before attempting to read,-    but that leaves a small race window where the data can be read-    from the file descriptor before we issue our blocking read().-  * readRawBufferNoBlock for a blocking FD--NOTE [2363]:--In the threaded RTS we could just make safe calls to read()/write()-for file descriptors in blocking mode without worrying about blocking-other threads, but the problem with this is that the thread will be-uninterruptible while it is blocked in the foreign call.

These modes have the following--- effects. For output, items are written out, or /flushed/,--- from the internal buffer according to the buffer mode:------  * /line-buffering/: the entire output buffer is flushed---    whenever a newline is output, the buffer overflows, ---    a 'System.IO.hFlush' is issued, or the handle is closed.------  * /block-buffering/: the entire buffer is written out whenever it---    overflows, a 'System.IO.hFlush' is issued, or the handle is closed.------  * /no-buffering/: output is written immediately, and never stored---    in the buffer.------ An implementation is free to flush the buffer more frequently,--- but not less frequently, than specified above.--- The output buffer is emptied as soon as it has been written out.------ Similarly, input occurs according to the buffer mode for the handle:------  * /line-buffering/: when the buffer for the handle is not empty,---    the next item is obtained from the buffer; otherwise, when the---    buffer is empty, characters up to and including the next newline---    character are read into the buffer.  No characters are available---    until the newline character is available or the buffer is full.------  * /block-buffering/: when the buffer for the handle becomes empty,---    the next block of data is read into the buffer.------  * /no-buffering/: the next input item is read and returned.---    The 'System.IO.hLookAhead' operation implies that even a no-buffered---    handle may require a one-character buffer.------ The default buffering mode when a handle is opened is--- implementation-dependent and may depend on the file system object--- which is attached to that handle.--- For most implementations, physical files will normally be block-buffered --- and terminals will normally be line-buffered.--data BufferMode  - = NoBuffering  -- ^ buffering is disabled if possible.- | LineBuffering-                -- ^ line-buffering should be enabled if possible.- | BlockBuffering (Maybe Int)-                -- ^ block-buffering should be enabled if possible.-                -- The size of the buffer is @n@ items if the argument-                -- is 'Just' @n@ and is otherwise implementation-dependent.-   deriving (Eq, Ord, Read, Show)--{--[note Buffering Implementation]--Each Handle has two buffers: a byte buffer (haByteBuffer) and a Char-buffer (haCharBuffer).  --[note Buffered Reading]--For read Handles, bytes are read into the byte buffer, and immediately-decoded into the Char buffer (see-GHC.IO.Handle.Internals.readTextDevice).  The only way there might be-some data left in the byte buffer is if there is a partial multi-byte-character sequence that cannot be decoded into a full character.--Note that the buffering mode (haBufferMode) makes no difference when-reading data into a Handle.  When reading, we can always just read all-the data there is available without blocking, decode it into the Char-buffer, and then provide it immediately to the caller.--[note Buffered Writing]--Characters are written into the Char buffer by e.g. hPutStr.  At the-end of the operation, or when the char buffer is full, the buffer is-decoded to the byte buffer (see writeCharBuffer).  This is so that we-can detect encoding errors at the right point.--Hence, the Char buffer is always empty between Handle operations.--[note Buffer Sizing]--The char buffer is always a default size (dEFAULT_CHAR_BUFFER_SIZE).-The byte buffer size is chosen by the underlying device (via its-IODevice.newBuffer).  Hence the size of these buffers is not under-user control.--There are certain minimum sizes for these buffers imposed by the-library (but not checked):-- - we must be able to buffer at least one character, so that-   hLookAhead can work-- - the byte buffer must be able to store at least one encoded-   character in the current encoding (6 bytes?)-- - when reading, the char buffer must have room for two characters, so-   that we can spot the \r\n sequence.--How do we implement hSetBuffering?--For reading, we have never used the user-supplied buffer size, because-there's no point: we always pass all available data to the reader-immediately.  Buffering would imply waiting until a certain amount of-data is available, which has no advantages.  So hSetBuffering is-essentially a no-op for read handles, except that it turns on/off raw-mode for the underlying device if necessary.--For writing, the buffering mode is handled by the write operations-themselves (hPutChar and hPutStr).  Every write ends with-writeCharBuffer, which checks whether the buffer should be flushed-according to the current buffering mode.  Additionally, we look for-newlines and flush if the mode is LineBuffering.--[note Buffer Flushing]--** Flushing the Char buffer--We must be able to flush the Char buffer, in order to implement-hSetEncoding, and things like hGetBuf which want to read raw bytes.--Flushing the Char buffer on a write Handle is easy: it is always empty.--Flushing the Char buffer on a read Handle involves rewinding the byte-buffer to the point representing the next Char in the Char buffer.-This is done by-- - remembering the state of the byte buffer *before* the last decode-- - re-decoding the bytes that represent the chars already read from the-   Char buffer.  This gives us the point in the byte buffer that-   represents the *next* Char to be read.--In order for this to work, after readTextHandle we must NOT MODIFY THE-CONTENTS OF THE BYTE OR CHAR BUFFERS, except to remove characters from-the Char buffer.--** Flushing the byte buffer--The byte buffer can be flushed if the Char buffer has already been-flushed (see above).  For a read Handle, flushing the byte buffer-means seeking the device back by the number of bytes in the buffer,-and hence it is only possible on a seekable Handle.---}---- ------------------------------------------------------------------------------ Newline translation---- | The representation of a newline in the external file or stream.-data Newline = LF    -- ^ '\n'-             | CRLF  -- ^ '\r\n'-             deriving (Eq, Ord, Read, Show)---- | Specifies the translation, if any, of newline characters between--- internal Strings and the external file or stream.

But if-there is one parenthesis parsed, then the required precedence level-drops to 0 again, and parsing inside p may succeed.--'appPrec' is just the precedence level of function application.  So,-if we are parsing function application, we'd better require the-precedence level to be at least 'appPrec'. Otherwise, we have to put-parentheses around it.--'step' is used to increase the precedence levels inside a-parser, and can be used to express left- or right- associativity. For-example, % is defined to be left associative, so we only increase-precedence on the right hand side.--Note how step is used in for example the Maybe parser to increase the-precedence beyond appPrec, so that basically only literals and-parenthesis-like objects such as (...) and [...] can be an argument to-'Just'.--\begin{code}-instance Read a => Read (Maybe a) where-  readPrec =-    parens-    (do L.Ident "Nothing" <- lexP-        return Nothing-     +++-     prec appPrec (-        do L.Ident "Just" <- lexP-           x              <- step readPrec-           return (Just x))-    )--  readListPrec = readListPrecDefault-  readList     = readListDefault--instance Read a => Read [a] where-  readPrec     = readListPrec-  readListPrec = readListPrecDefault-  readList     = readListDefault--instance  (Ix a, Read a, Read b) => Read (Array a b)  where-    readPrec = parens $ prec appPrec $-               do L.Ident "array" <- lexP-                  theBounds <- step readPrec-                  vals   <- step readPrec-                  return (array theBounds vals)--    readListPrec = readListPrecDefault-    readList     = readListDefault--instance Read L.Lexeme where-  readPrec     = lexP-  readListPrec = readListPrecDefault-  readList     = readListDefault-\end{code}---%*********************************************************-%*                                                      *-\subsection{Numeric instances of Read}-%*                                                      *-%*********************************************************--\begin{code}-readNumber :: Num a => (L.Lexeme' -> ReadPrec a) -> ReadPrec a--- Read a signed number-readNumber convert =-  parens-  ( do x <- lexP'-       case x of-         L.Symbol' "-" -> do y <- lexP'-                             n <- convert y-                             return (negate n)--         _   -> convert x-  )---convertInt :: Num a => L.Lexeme' -> ReadPrec a-convertInt (L.Number n)- | Just i <- L.numberToInteger n = return (fromInteger i)-convertInt _ = pfail--convertFrac :: forall a .

  arbitrary and kept small to not unduly increase the number of rules.-    0 and 1 are excluded based on the assumption that nobody would-    write x^0 or x^1 in code and the cases where an exponent could-    be statically resolved to 0 or 1 are rare.--    It might be desirable to have corresponding rules also for-    exponents of other types, in particular Word, but we can't-    have those rules here (importing GHC.Word or GHC.Int would-    create a cyclic module dependency), and it's doubtful they-    would fire, since the exponents of other types tend to get-    floated out before the rule

So the table should contain a weak pointer--- to the key, not an ordinary pointer.  The pointer to the value must--- not be weak, because the only reference to the value might indeed be--- from the memo table.   --- --- So it looks as if the memo table will keep all its values--- alive for ever.  One way to solve this is to purge the table--- occasionally, by deleting entries whose keys have died.--- --- The weak pointers in this library--- support another approach, called /finalization/.--- When the key referred to by a weak pointer dies, the storage manager--- arranges to run a programmer-specified finalizer.  In the case of memo--- tables, for example, the finalizer could remove the key\/value pair--- from the memo table.  --- --- Another difficulty with the memo table is that the value of a--- key\/value pair might itself contain a pointer to the key.--- So the memo table keeps the value alive, which keeps the key alive,--- even though there may be no other references to the key so both should--- die.

Suppose, for example, the value of one weak pointer-refers to the key of another...does that keep the key alive?--The behaviour is simply this:-- *  If a weak pointer (object) refers to an /unreachable/-    key, it may be finalized.-- *  Finalization means (a) arrange that subsequent calls-    to 'deRefWeak' return 'Nothing'; and (b) run the finalizer.--This behaviour depends on what it means for a key to be reachable.-Informally, something is reachable if it can be reached by following-ordinary pointers from the root set, but not following weak pointers.-We define reachability more precisely as follows A heap object is-reachable if:-- * It is a member of the /root set/.-- * It is directly pointed to by a reachable object, other than-   a weak pointer object.-- * It is a weak pointer object whose key is reachable.-- * It is the value or finalizer of an object whose key is reachable.--}-

Byte vectors are encoded as lazy lists of strict 'Word8'--- arrays of bytes. They provide a means to manipulate large byte vectors--- without requiring the entire vector be resident in memory.------ Some operations, such as concat, append, reverse and cons, have--- better complexity than their "Data.ByteString" equivalents, due to--- optimisations resulting from the list spine structure. And for other--- operations lazy ByteStrings are usually within a few percent of--- strict ones, but with better heap usage. For data larger than the--- available memory, or if you have tight memory constraints, this--- module will be the only option. The default chunk size is 64k, which--- should be good in most circumstances. For people with large L2--- caches, you may want to increase this to fit your cache.------ This module is intended to be imported @qualified@, to avoid name--- clashes with "Prelude" functions.

GHC 7.0 and higher does this by itself when it sees th--- unfolding of a function -- that is why all public functions are marked--- INLINABLE (that exposes the unfolding).----- [Note: Using INLINE]--- ~~~~~~~~~~~~~~~~~~~~--- For other compilers and GHC pre 7.0, we mark some of the functions INLINE.--- We mark the functions that just navigate down the tree (lookup, insert,--- delete and similar). That navigation code gets inlined and thus specialized--- when possible. There is a price to pay -- code growth. The code INLINED is--- therefore only the tree navigation, all the real work (rebalancing) is not--- INLINED by using a NOINLINE.------ All methods marked INLINE have to be nonrecursive -- a 'go' function doing--- the real work is provided.----- [Note: Type of local 'go' function]--- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--- If the local 'go' function uses an Ord class, it sometimes heap-allocates--- the Ord dictionary when the 'go' function does not have explicit type.--- In that case we give 'go' explicit type. But this slightly decrease--- performance, as the resulting 'go' function can float out to top level.----- [Note: Local 'go' functions and capturing]--- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--- As opposed to IntMap, when 'go' function captures an argument, increased--- heap-allocation can occur: sometimes in a polymorphic function, the 'go'--- floats out of its enclosing function and then it heap-allocates the--- dictionary and the argument. Maybe it floats out too late and strictness--- analyzer cannot see that these could be passed on stack.------ For example, change 'member' so that its local 'go' function is not passing--- argument k and then look at the resulting code for hedgeInt.----- [Note: Order of constructors]--- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--- The order of constructors of Map matters when considering performance.--- Currently in GHC 7.0, when type has 2 constructors, a forward conditional--- jump is made when successfully matching second constructor. Successful match--- of first constructor results in the forward jump not taken.--- On GHC 7.0, reordering constructors from Tip | Bin to Bin | Tip--- improves the benchmark by up to 10% on

GHC 7.0 and higher does this by itself when it sees th--- unfolding of a function -- that is why all public functions are marked--- INLINABLE (that exposes the unfolding).----- [Note: Using INLINE]--- ~~~~~~~~~~~~~~~~~~~~--- For other compilers and GHC pre 7.0, we mark some of the functions INLINE.--- We mark the functions that just navigate down the tree (lookup, insert,--- delete and similar). That navigation code gets inlined and thus specialized--- when possible. There is a price to pay -- code growth. The code INLINED is--- therefore only the tree navigation, all the real work (rebalancing) is not--- INLINED by using a NOINLINE.------ All methods marked INLINE have to be nonrecursive -- a 'go' function doing--- the real work is provided.----- [Note: Type of local 'go' function]--- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--- If the local 'go' function uses an Ord class, it sometimes heap-allocates--- the Ord dictionary when the 'go' function does not have explicit type.--- In that case we give 'go' explicit type. But this slightly decrease--- performance, as the resulting 'go' function can float out to top level.----- [Note: Local 'go' functions and capturing]--- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--- As opposed to IntMap, when 'go' function captures an argument, increased--- heap-allocation can occur: sometimes in a polymorphic function, the 'go'--- floats out of its enclosing function and then it heap-allocates the--- dictionary and the argument. Maybe it floats out too late and strictness--- analyzer cannot see that these could be passed on stack.------ For example, change 'member' so that its local 'go' function is not passing--- argument k and then look at the resulting code for hedgeInt.----- [Note: Order of constructors]--- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--- The order of constructors of Map matters when considering performance.--- Currently in GHC 7.0, when type has 2 constructors, a forward conditional--- jump is made when successfully matching second constructor. Successful match--- of first constructor results in the forward jump not taken.--- On GHC 7.0, reordering constructors from Tip | Bin to Bin | Tip--- improves the benchmark by up to 10% on

Data.List.sortBy cmp . toList--- which does not get deforested automatically, it would appear.------ Unstable sorting is performed by a heap sort implementation based on--- pairing heaps.  Because the internal structure of sequences is quite--- varied, it is difficult to get blocks of elements of roughly the same--- length, which would improve merge sort performance.  Pairing heaps,--- on the other hand, are relatively resistant to the effects of merging--- heaps of wildly different sizes, as guaranteed by its amortized--- constant-time merge operation.  Moreover, extensive use of SpecConstr--- transformations can be done on pairing heaps, especially when we're--- only constructing them to immediately be unrolled.------ On purely random sequences of length 50000, with no RTS options,--- I get the following statistics, in which heapsort is about 42.5%--- faster:  (all comparisons done with -O2)------ Times (ms)            min      mean    +/-sd    median    max--- to/from list:       103.802  108.572    7.487  106.436  143.339--- unstable heapsort:   60.686   62.968    4.275   61.187   79.151------ Heapsort, it would seem, is less of a memory hog than Data.List.sortBy.--- The gap is narrowed when more memory is available, but heapsort still--- wins, 15% faster, with +RTS -H128m:------ Times (ms)            min    mean    +/-sd  median    max--- to/from list:       42.692  45.074   2.596  44.600  56.601--- unstable heapsort:  37.100  38.344   3.043  37.715  55.526------ In addition, on strictly increasing sequences the gap is even wider--- than normal; heapsort is 68.5% faster with no RTS options:--- Times (ms)            min    mean    +/-sd  median    max--- to/from list:       52.236  53.574   1.987  53.034  62.098--- unstable heapsort:  16.433  16.919   0.931  16.681  21.622------ This may be attributed to the elegant nature of the pairing heap.------ wasserman.louis@gmail.com, 7/20/09----------------------------------------------------------------------------- | /O(n log n)/.

Of course, left-biasing can only be observed--- when equality is an equivalence relation instead of structural--- equality.---------------------------------------------------------------------------------- [Note: Using INLINABLE]--- ~~~~~~~~~~~~~~~~~~~~~~~--- It is crucial to the performance that the functions specialize on the Ord--- type when possible. GHC 7.0 and higher does this by itself when it sees th--- unfolding of a function -- that is why all public functions are marked--- INLINABLE (that exposes the unfolding).----- [Note: Using INLINE]--- ~~~~~~~~~~~~~~~~~~~~--- For other compilers and GHC pre 7.0, we mark some of the functions INLINE.--- We mark the functions that just navigate down the tree (lookup, insert,--- delete and similar). That navigation code gets inlined and thus specialized--- when possible. There is a price to pay -- code growth. The code INLINED is--- therefore only the tree navigation, all the real work (rebalancing) is not--- INLINED by using a NOINLINE.------ All methods marked INLINE have to be nonrecursive -- a 'go' function doing--- the real work is provided.----- [Note: Type of local 'go' function]--- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--- If the local 'go' function uses an Ord class, it sometimes heap-allocates--- the Ord dictionary when the 'go' function does not have explicit type.--- In that case we give 'go' explicit type. But this slightly decrease--- performance, as the resulting 'go' function can float out to top level.----- [Note: Local 'go' functions and capturing]--- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--- As opposed to IntSet, when 'go' function captures an argument, increased--- heap-allocation can occur: sometimes in a polymorphic function, the 'go'--- floats out of its enclosing function and then it heap-allocates the--- dictionary and the argument. Maybe it floats out too late and strictness--- analyzer cannot see that these could be passed on stack.------ For example, change 'member' so that its local 'go' function is not passing--- argument x and then look at the resulting code for hedgeInt.----- [Note: Order of constructors]--- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--- The order of constructors of Set matters when considering performance.--- Currently in GHC 7.0, when type has 2 constructors, a forward conditional--- jump is made when successfully matching second constructor. Successful match--- of first constructor results in the forward jump not taken.--- On GHC 7.0, reordering constructors from Tip | Bin to Bin | Tip--- improves the benchmark by up to 10% on x86.--module Data.Set.Base (-            -- * Set type-              Set(..)       -- instance Eq,Ord,Show,Read,Data,Typeable--            -- * Operators-            , (\\)--            -- * Query-            , null-            , size-            , member-            , notMember-            , lookupLT-            , lookupGT-            , lookupLE-            , lookupGE-            , isSubsetOf-            , isProperSubsetOf--            -- * Construction-            , empty-            , singleton-            , insert-            , delete--            -- * Combine-            , union-            , unions-            , difference-            , intersection--            -- * Filter-            , filter-            , partition-            , split-            , splitMember--            -- * Map-            , map-            , mapMonotonic--            -- * Folds-            , foldr-            , foldl-            -- ** Strict folds-            , foldr'-            , foldl'-            -- ** Legacy folds-            , fold--            -- * Min\/Max-            , findMin-            , findMax-            , deleteMin-            , deleteMax-            , deleteFindMin-            , deleteFindMax-            , maxView-            , minView--            -- * Conversion--            -- ** List-            , elems-            , toList-            , fromList--            -- ** Ordered list-            , toAscList-            , toDescList-            , fromAscList-            , fromDistinctAscList--            -- * Debugging-            , showTree-            , showTreeWith-            , valid--            -- Internals (for testing)-            , bin-            , balanced-            , join-            , merge-            ) where--import Prelude hiding (filter,foldl,foldr,null,map)-import qualified Data.List as List-import Data.Monoid (Monoid(..))-import qualified Data.Foldable as Foldable-import Data.Typeable-import Control.DeepSeq (NFData(rnf))--#if __GLASGOW_HASKELL__-import GHC.Exts ( build )-import Text.Read-import Data.Data-#endif---- Use macros to define strictness of functions.--- STRICT_x_OF_y denotes an y-ary function strict in the x-th parameter.--- We do not use BangPatterns, because they are not in any standard and we--- want the compilers to be compiled by as many compilers as possible.-#define STRICT_1_OF_2(fn) fn arg _ | arg `seq` False = undefined-#define STRICT_1_OF_3(fn) fn arg _ _ | arg `seq` False = undefined--{---------------------------------------------------------------------  Operators---------------------------------------------------------------------}-infixl 9 \\ ------ | /O(n+m)/.

GHC 7.0 and higher does this by itself when it sees th--- unfolding of a function -- that is why all public functions are marked--- INLINABLE (that exposes the unfolding).----- [Note: Using INLINE]--- ~~~~~~~~~~~~~~~~~~~~--- For other compilers and GHC pre 7.0, we mark some of the functions INLINE.--- We mark the functions that just navigate down the tree (lookup, insert,--- delete and similar). That navigation code gets inlined and thus specialized--- when possible. There is a price to pay -- code growth. The code INLINED is--- therefore only the tree navigation, all the real work (rebalancing) is not--- INLINED by using a NOINLINE.------ All methods marked INLINE have to be nonrecursive -- a 'go' function doing--- the real work is provided.----- [Note: Type of local 'go' function]--- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--- If the local 'go' function uses an Ord class, it sometimes heap-allocates--- the Ord dictionary when the 'go' function does not have explicit type.--- In that case we give 'go' explicit type. But this slightly decrease--- performance, as the resulting 'go' function can float out to top level.----- [Note: Local 'go' functions and capturing]--- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--- As opposed to IntMap, when 'go' function captures an argument, increased--- heap-allocation can occur: sometimes in a polymorphic function, the 'go'--- floats out of its enclosing function and then it heap-allocates the--- dictionary and the argument. Maybe it floats out too late and strictness--- analyzer cannot see that these could be passed on stack.------ For example, change 'member' so that its local 'go' function is not passing--- argument k and then look at the resulting code for hedgeInt.----- [Note: Order of constructors]--- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~--- The order of constructors of Map matters when considering performance.--- Currently in GHC 7.0, when type has 2 constructors, a forward conditional--- jump is made when successfully matching second constructor. Successful match--- of first constructor results in the forward jump not taken.--- On GHC 7.0, reordering constructors from Tip | Bin to Bin | Tip--- improves the benchmark by up to 10% on
