NAME
Test::AutoBuild::Stage::SetNice - Alter the scheduling priority of builderSYNOPSIS
use Test::AutoBuild::Stage::SetNice
DESCRIPTION
This module provides the ability to alter the scheduling priority of the build process, typically lowering it to avoid monopolising all the resources of the host machine. This is analogous to launching the builder process through the nice(1) command.CONFIGURATION
In addition to the standard parameters defined by the Test::AutoBuild::Stage module, this module accepts one entry in the "options" parameter:- nice-level
- An integer in the range -20 (highest priority) to 19 (lowest priority) indicating what schedular priority to give to the builder. NB, typically you will be unable to set a priority less than zero, since the builder does not run as root. If omitted, the default value is 19 to ensure lowest priority is taken.
EXAMPLE
{ name = renice label = Set Process Priority module = Test::AutoBuild::Stage::SetNice critical = 0 options = { nice-level = 19 } }
METHODS
- $stage->init(%params);
- Override super class to initialize the default nice level if non was specified. It is not neccesary to call this method since it is called automatically by the "new" method.
- $stage->process($runtime);
- Attempt to change the priority of the builder process according to the "nice-level" option. If unsuccessful, marks the stage as having "failed". Since this is a recoverable error, it is usual to set this stage as non-critical.
