NAME

Test::AutoBuild::Monitor::Pipe - Monitor progress through a pipe

SYNOPSIS

my $monitor = Test::AutoBuild::Pipe->new(
options => {
path => "/var/lib/builder/monitor",
mode = 0644
},
env => \%env);
# Emit some events
$monitor->notify("begin-stage", "build", time);
$monitor->notify("end-stage", "build", time, $status);

DESCRIPTION

This module sends events down a pipe, one line per event. The data is formatted in the scheme:

begin-stage('build', '12450052')
end-stage('build', '12452345', 'failed')

CONFIGURATION

Along with the standard configuration parameters for Test::AutoBuild::Monitor, this module expects two options to be set:

path

The full path to the FIFO pipe. The pipe will be created if it does not already exist

mask

The permissions mask to use when creating the file, in decimal, not octal. Defaults to 493, which is 0755 in octal, if not specified.

EXAMPLE

pipe = {
label = FIFO monitor
module = Test::AutoBuild::Monitor::Pipe
options = {
path = /var/lib/builder/monitor
# 0755 in decimal
mask = 493
}
}

METHODS

$monitor->init(%params);

This method initializes a new monitor & is called automatically by the new method. The %params parameters are passed through from the new method.

$monitor->process($event_name, @args);

This method writes the event to the FIFO pipe and flushes the output stream
