DESCRIPTION

This class gives access to the "builder farm", to actions like initialising the builders, compiling packages and calculating which builders should compile which packages.

The builder farm uses the Arepa configuration to get the needed information.

METHODS

new($path)
new($path, %options): Creates a new builder farm access object, using the configuration file in $path. The only valid option is builder_config_dir (see Arepa::Config documentation for details).
last_build_log: Returns the output of the last compilation attempt.
package_db: Returns a Arepa::PackageDb object pointing to the package database used by the builder farm.
get_builder_config($builder_name): Returns a hash with the configuration for the builder $builder_name.
builder_type_module($type): Returns the module name implementing the features for the builder type $type.
builder_module($builder_name): Returns the module name implementing the features for the given $builder_name.
builder($builder_name): Returns the builder object identified by $builder_name.
init_builders: Initialises all the builders. It should be called once per machine boot (e.g. inside an init script).
init_builder($builder_name): Initialises the builder $builder_name.
uninit_builders: Uninitialises all the builders. It should be called once per machine shutdown (e.g. inside an init script).
uninit_builder($builder_name): Uninitialises the builder $builder_name.
compile_package_from_dsc($builder_name, $dsc_file, %opts): Compiles the source package described by the .dsc file $dsc_file using the builder $builder_name, and puts the resulting .deb files in the appropriate output directory. You can specify it with the output_dir option in %opts. If no directory is specified, they're left in the current directory.
bin_nmu_id($src_pkg_attrs, $builder_name): Returns the binary NMU id that $builder_name should use when building the given source package. The first parameter, $src_pkg_attrs, is a hashref with the attributes of the source package (see get_source_package_by_id in Arepa::PackageDb). The binNMU id is a number, or undef if the given builder should not build the given source package as a binNMU.
compile_package_from_queue($builder_name, $request_id, %opts): Compiles the request $request_id using the builder $builder_name, and puts the resulting .deb files in the output directory (by default, the current directory). The only valid option is output_dir (to change the output directory).
request_package_compilation($source_id): Adds a compilation request for the source package with id $source_id.
get_compilation_targets($source_id): Returns an array of targets for the given source package $source_id. Each target is an arrayref with two elements: architecture and distribution.
get_matching_builders($architecture, $distribution): Gets the builders that should compile packages for the given $architecture and $distribution. It returns a list of builder names.
register_source_package(%source_package_attrs): Registers the source package with the given %source_package_attrs. This method is seldom used, as you would normally add the source package to the repository first (using Arepa::Repository), which automatically registers the source package.
canonical_distribution($arch, $distro): Calculates the canonical distribution, ie. the distribution as registered by one of the Arepa builders, given an architecture and distribution from a changes file or similar. It's needed for the reprepro call. If reprepro accepted "reprepro includesrc 'funnydistro' ...", having 'funnydistro' in the AlsoAcceptFor list, this wouldn't be necessary.
