Test::AutoBuild::StageUsertContributed Perl Test::AutoBuild::Stage::SetNice(3)NAMETest::AutoBuild::Stage::SetNice - Alter the scheduling priority of
builder
SYNOPSIS
use Test::AutoBuild::Stage::SetNiceDESCRIPTION
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.
