Running the pipelines
runAllPipelines :: WorkerLimit -> MakeEnv -> [MakeAction] -> IO () #
Run the given actions and then wait for them all to finish.
Arguments
| :: WorkerLimit | How to limit work parallelism |
| -> HscEnv | The basic HscEnv which is augmented with specific info for each module |
| -> (GhcMessage -> AnyGhcDiagnostic) | |
| -> Maybe Messager | Optional custom messager to use to report progress |
| -> [MakeAction] | The build plan for all the module nodes |
| -> IO () |
Build and run a pipeline
runSeqPipelines :: HscEnv -> (GhcMessage -> AnyGhcDiagnostic) -> Maybe Messager -> [MakeAction] -> IO () #
runPipelines :: WorkerLimit -> HscEnv -> (GhcMessage -> AnyGhcDiagnostic) -> Maybe Messager -> [MakeAction] -> IO () #
Worker limit
data WorkerLimit #
This describes what we use to limit the number of jobs, either we limit it ourselves to a specific number or we have an external parallelism semaphore limit it for us.
