NAME

Test::AutoBuild::Stage::Iterator - Run a set of stages for each module

SYNOPSIS

use Test::AutoBuild::Stage::Iterator

DESCRIPTION

This stage iterates over the (ordered) list of modules, running a set of sub-stages against each one. The current module being passed into the run method of each stage. If the sub-stages are iterator-aware this enables a configuration to be setup to generate incremental HTML status pages during the course of the build cycle.

CONFIGURATION

In addition to the standard parameters defined by the Test::AutoBuild::Stage module, this module also handles the optional stages parameter to specify a list of sub-stages. Sub-stages are listed in the same format as top level stages, ie an array of hashes.

EXAMPLE

  {
    name = build
    label = Build iterator
    module = Test::AutoBuild::Stage::Iterator
    # Don't abort entire cycle if the module build fails
    critical = 0
    stages = (
      # Basic build
      {
	name = build
	label = Build
	module = Test::AutoBuild::Stage::Build
	options = {
	  ...snip build options...
	}
      }
      # Status pages
      {
	name = html
	label = HTML status pages
	module = Test::AutoBuild::Stage::HTMLStatus
	options = {
	  ...snip status options...
	}
      }
    )
  }

METHODS

$stage->init(%params);

Overrides the super-class to add in handling of the optional stages parameter for defining sub-stages. It is not neccessary to call this method, since it is called by the new method automatically.

my @stages = $stage->stages();

Retrieves the list of sub-stages that belong to this group. The elements in the array are instances of Test::AutoBuild::Stage module.

$stage->process($runtime);

Iterates over all modules (in depenedancy sorted order), for each module, running the set of configured sub-stages. The sub-stages will have the name of the current module passed in as the second parameter to the run method. If any sub-stages fails & that stage is marked as critical, this stage will be marked as failing and return control immediately. If the sub-stage is non-critical, then the iterator will continue processing.
