Description

Functions for performing whole heap census in the style of the normal - heap profiling

Synopsis

Documentation

profile :: FilePath -> Int -> Debuggee -> IO () Source #

Peform a profile at the given interval (in seconds), the result will be rendered after each iteration using eventlog2html.

censusClosureType :: [ClosurePtr] -> DebugM CensusByClosureType Source #

Perform a heap census in the same style as the -hT profile.

census2LevelClosureType :: [ClosurePtr] -> DebugM CensusByClosureType Source #

Perform a 2-level census where the keys are the type of the closure in addition to the type of ptrs of the closure. This can be used to distinguish between lists of different type for example.

closureCensusBy :: forall k v. (Semigroup v, Ord k) => (ClosurePtr -> SizedClosure -> DebugM (Maybe (k, v))) -> [ClosurePtr] -> DebugM (Map k v) Source #

General function for performing a heap census in constant memory
