GHC.Exts.Heap

Description

With this module, you can investigate the heap representation of Haskell values, i.e. to investigate sharing and lazy evaluation.

Synopsis

Closure types

type Closure = GenClosure Box Source #

data GenClosure b Source #

This is the representation of a Haskell value on the heap. It reflects https://gitlab.haskell.org/ghc/ghc/blob/master/rts/include/rts/storage/Closures.h

The data type is parametrized by b: the type to store references in. Usually this is a Box with the type synonym Closure.

All Heap objects have the same basic layout. A header containing a pointer to the info table and a payload with various fields. The info field below always refers to the info table pointed to by the header. The remaining fields are the payload.

See https://gitlab.haskell.org/ghc/ghc/wikis/commentary/rts/storage/heap-objects for more information.

Constructors

ConstrClosure

A data constructor

Fields

FunClosure

A function

Fields

ThunkClosure

A thunk, an expression not obviously in head normal form

Fields

SelectorClosure

A thunk which performs a simple selection operation

Fields

PAPClosure

An unsaturated function application

Fields

APClosure

A function application

Fields

APStackClosure

A suspended thunk evaluation

Fields

IndClosure

A pointer to another closure, introduced when a thunk is updated to point at its value

Fields

BCOClosure

A byte-code object (BCO) which can be interpreted by GHC's byte-code interpreter (e.g. as used by GHCi)

Fields

  • info :: !StgInfoTable
     
  • instrs :: !b

    A pointer to an ArrWords of instructions

  • literals :: !b

    A pointer to an ArrWords of literals

  • bcoptrs :: !b

    A pointer to an ArrWords of byte code objects

  • arity :: !HalfWord

    Arity of the partial application

  • size :: !HalfWord

    The size of this BCO in words

  • bitmap :: ![Word]

    An StgLargeBitmap describing the pointerhood of its args/free vars

BlackholeClosure

A thunk under evaluation by another thread

Fields

ArrWordsClosure

A ByteArray#

Fields

MutArrClosure

A SmallMutableArray#

Since: 8.10.1

Fields

MVarClosure

Fields

MutVarClosure

A MutVar#

Fields

BlockingQueueClosure

An STM blocking queue.

Fields

WeakClosure 

Fields

TSOClosure

Representation of StgTSO: A Thread State Object. The values for what_next, why_blocked and flags are defined in Constants.h.

Fields

StackClosure

Representation of StgStack: The 'tsoStack ' of a TSOClosure.

Fields

IntClosure

Primitive Int

Fields

WordClosure

Primitive Word

Fields

Int64Closure

Primitive Int64

Fields

Word64Closure

getClosureDataFromHeapRep :: ByteArray# -> Ptr StgInfoTable -> [b] -> IO (GenClosure b) Source #

Convert an unpacked heap object, to a `GenClosure b`. The inputs to this function can be generated from a heap object using unpackClosure#.

getClosureDataFromHeapRepPrim Source #

Arguments

:: IO (String, String, String)

A continuation used to decode the constructor description field, in ghc-debug this code can lead to segfaults because dataConNames will dereference a random part of memory.

-> (Ptr a -> IO (Maybe CostCentreStack))

A continuation which is used to decode a cost centre stack In ghc-debug, this code will need to call back into the debuggee to fetch the representation of the CCS before decoding it. Using peekTopCCS for this argument can lead to segfaults in ghc-debug as the CCS argument will point outside the copied closure.

-> StgInfoTable

The StgInfoTable of the closure, extracted from the heap representation.

-> ByteArray#

Heap representation of the closure as returned by unpackClosure#. This includes all of the object including the header, info table pointer, pointer data, and non-pointer data. The ByteArray# may be pinned or unpinned.

-> [b]

Pointers in the payload of the closure, extracted from the heap representation as returned by `collect_pointers()` in c. The type b is some representation of a pointer e.g. Any or `Ptr Any`.

-> IO (GenClosure b)

Heap representation of the closure.

Closure inspection

getBoxedClosureData :: Box -> IO Closure Source #

Like getClosureData, but taking a Box, so it is easier to work with.

allClosures :: GenClosure b -> [b] Source #

For generic code, this function returns all referenced closures.

Boxes

data Box Source #

An arbitrary Haskell value in a safe Box. The point is that even unevaluated thunks can safely be moved around inside the Box, and when required, e.g. in getBoxedClosureData, the function knows how far it has to evaluate the argument.

Methods

showsPrec :: Int -> Box -> ShowS #

show :: Box -> String #

showList :: [Box] -> ShowS #

asBox :: a -> Box Source #

This takes an arbitrary value and puts it into a box. Note that calls like

asBox (head list)

will put the thunk "head list" into the box, not the element at the head of the list. For that, use careful case expressions:

case list of x:_ -> asBox x

areBoxesEqual :: Box -> Box -> IO Bool Source #

Boxes can be compared, but this is not pure, as different heap objects can, after garbage collection, become the same object.
