CPU options impacting cryptography implementation and library performance.

The identifier of the CPU-time clock associated with the calling process. For this clock, the value returned by getTime represents the amount of execution time of the current process.

newtype ProcessFailure

streamly-process Streamly.Internal.System.Process Streamly.System.Command Streamly.System.Process

An exception that is raised when a process fails.

ProcessFailure :: Int -> ProcessFailure

streamly-process Streamly.Internal.System.Process Streamly.System.Command Streamly.System.Process

The exit code of the process.

processorOptions :: [ProcessorOption]

cryptonite Crypto.System.CPU, crypton Crypto.System.CPU

Options which have been enabled at compile time and are supported by the current CPU.

processID :: PipeHandle -> ProcessID

MissingH System.Cmd.Utils

processBytes :: (MonadCatch m, MonadAsync m) => FilePath -> [String] -> Stream m Word8 -> Stream m Word8

streamly-process Streamly.Internal.System.Process Streamly.System.Process

Deprecated: Please use pipeBytes instead.

processChunks :: (MonadCatch m, MonadAsync m) => FilePath -> [String] -> Stream m (Array Word8) -> Stream m (Array Word8)

streamly-process Streamly.Internal.System.Process Streamly.System.Process

Deprecated: Please use pipeChunks instead.

processorID :: CPU -> !Word32

cpuinfo System.CPU

Logical Processor Index

timed_post_process :: TimedFileLogSpec -> FilePath -> IO ()

fast-logger System.Log.FastLogger.File

processing function called asynchronously after a file is added to the rotation

class Preprocessor cpp

language-c Language.C.System.Preprocess

Preprocessor encapsulates the abstract interface for invoking C preprocessors

isPreprocessed :: FilePath -> Bool

language-c Language.C.System.Preprocess

guess whether a file is preprocessed (file end with .i)

runPreprocessor :: Preprocessor cpp => cpp -> CppArgs -> IO (Either ExitCode InputStream)

language-c Language.C.System.Preprocess

run the preprocessor and return an InputStream if preprocesssing succeeded

type ConcurrentProcessHandle = ProcessHandle

concurrent-output System.Console.Concurrent System.Console.Concurrent.Internal

This alias is provided to avoid breaking backwards compatibility.

createProcessConcurrent :: CreateProcess -> IO (Maybe Handle, Maybe Handle, Maybe Handle, ProcessHandle)

concurrent-output System.Console.Concurrent System.Console.Concurrent.Internal

Wrapper around createProcess that prevents multiple processes that are running concurrently from writing to stdout/stderr at the same time. If the process does not output to stdout or stderr, it's run by createProcess entirely as usual. Only processes that can generate output are handled specially: A process is allowed to write to stdout and stderr in the usual way, assuming it can successfully take the output lock. When the output lock is held (ie, by another concurrent process, or because outputConcurrent is being called at the same time), the process is instead run with its stdout and stderr redirected to a buffer. The buffered output will be displayed as soon as the output lock becomes free. Note that the the process is waited for by a background thread, so unlike createProcess, neglecting to call waitForProcess will not result in zombie processess.

createProcessForeground :: CreateProcess -> IO (Maybe Handle, Maybe Handle, Maybe Handle, ProcessHandle)

concurrent-output System.Console.Concurrent System.Console.Concurrent.Internal

Wrapper around createProcess that makes sure a process is run in the foreground, with direct access to stdout and stderr. Useful when eg, running an interactive process. Note that the the process is waited for by a background thread, so unlike createProcess, neglecting to call waitForProcess will not result in zombie processess.

waitForProcessConcurrent :: ConcurrentProcessHandle -> IO ExitCode

concurrent-output System.Console.Concurrent System.Console.Concurrent.Internal

Same as waitForProcess; provided to avoid breaking backwards compatibility.

bgProcess :: CreateProcess -> IO (Maybe Handle, Maybe Handle, Maybe Handle, ProcessHandle)

concurrent-output System.Console.Concurrent.Internal

fgProcess :: CreateProcess -> IO (Maybe Handle, Maybe Handle, Maybe Handle, ProcessHandle)

concurrent-output System.Console.Concurrent.Internal

createProcess :: CreateProcess -> IO (Maybe Handle, Maybe Handle, Maybe Handle, ProcessHandle)

concurrent-output System.Process.Concurrent

Calls createProcessConcurrent

waitForProcess :: ProcessHandle -> IO ExitCode

concurrent-output System.Process.Concurrent

Calls waitForProcessConcurrent

newProcessGroup :: Bool -> Config -> Config

streamly-process Streamly.Internal.System.Process

If True the new process starts a new process group, becomes a process group leader, its pid becoming the process group id. See the POSIX setpgid man page. Default is False, the new process belongs to the parent's process group.

physicalProcessors :: [CPU] -> Int

cpuinfo System.CPU

Counts the number of physical processors in the system. A physical processor corresponds to a single CPU unit in a single socket, i.e. unless you have a multi-socket motherboard, this number will be one.
