NAME

PkgForge::Builder - A Moose role to be used by PkgForge builders.

VERSION

This documentation refers to PkgForge::Builder version 1.1.10

SYNOPSIS

package PkgForge::Builder::Foo;

use Moose;

with 'PkgForge::Builder';

sub verify_environment { ... }

sub run { ... }

sub submit_packages { ... }

DESCRIPTION

This is a role which gathers common functionality and sets some requirements on how a Package Forge builder class must be implemented.

ATTRIBUTES

The following attributes will be part of any class which implements this role:

resultsdir

This is the location of the directory into which results will be stored. This is the top-level directory, within this directory there will be a sub-directory for each job and within that a sub-directory for each task. This attribute must be specified.

logdir

This is the location of the directory into which the log file for the builds will be stored. This attribute must be specified. After completion of the build the log file will be copied to the specific results directory.

platform

This is the name of the platform for which the builder is being used, for example, f13 or sl5. This is a required attribute.

architecture

This is the name of the architecture for which the builder is being used, for example, i386 or x86_64. This does have any significance on some platforms so it is an optional attribute.

name

This is the name of the builder process. Normally you do not need to set this attribute, the default is the combination of the platform and architecture (if set) joined with a hyphen, e.g. platform f13 and architecture x86_64 gives a name of f13-x86_64.

timeout

This is the maximum time (in seconds) that the build process is allowed to take. Any process still running after this time should be killed.

error_policy

This is a string used to record the required response to any source package build errors. The currently supported values are retry and immediate. In immediate-mode the builder will stop as soon as any source package in the job fails to build. The default is retry-mode in which the builder will keep attempting to build more packages for the job as long as more build each time. This is very useful as it is often the situation that a job contains a set of packages where some of them have build-dependencies on others. Ordering them manually might be difficult so in the retry-mode although the job might take a bit longer to build there is an improved chance of complete success.

SUBROUTINES/METHODS

The following methods are available to all classes which implement this role:

build( $job, $resultsdir )

This method takes a PkgForge::Job object and the base results directory into which build results and log files are stored. These are passed into the new_topic method and then the newly created BuildTopic is passed to the run method (which must be implemented by each class). If the run method returns successfully then the submit_packages method (which must also be implemented by each class) is also called with the BuildTopic object.

new_topic( $job, $resultsdir )

This method takes a PkgForge::Job object and the base results directory into which build results and log files are stored. Within this directory a job/build specific directory tree will be assembled along the lines of uuid/platform-arch/ (e.g. i8Mq2Q0nRaG171vp1FpLxw/f13-i386/). This method returns a PkgForge::BuildTopic object which is a simple container for various information related to building a particular job on a particular platform and architecture. Most builder methods which do work expect to receive a BuildTopic object.

filter_sources($job)

This method takes the PkgForge::Job object and filters the source packages to find those which are suitable for this builder. For example, if the builder only accepts SRPMs then a list of only those packages which are in the PkgForge::Source::SRPM class will be returned.

This role requires that any implementing class provides the following methods:

verify_environment()

This method should validate the build environment and return 1 if everything is correct. If a problem is found the method should die with a useful message.

run($topic)

This is the main method which does the work of building the packages from source. It receives the PkgForge::BuildTopic object.

submit_packages($topic)

This method is used for submitting the built packages to the specified results directory. You need to pass in an PkgForge::BuildTopic object.

CONFIGURATION AND ENVIRONMENT

This module does not use any configuration files. You will need to install the correct build tools for the target platform (see the information in the documentation for the specific module you require).

DEPENDENCIES

This module is powered by Moose and uses MooseX::Types.
