parseRepoFile

public static org.apache.ambari.server.stack.RepositoryFolderAndXml parseRepoFile(File directory,
                                                                                  Collection<String> subDirs,
                                                                                  ModuleFileUnmarshaller unmarshaller)

Parses the repository file for a stack/service if exists.

Parameters:

directory - stack/service base directory

subDirs - stack/service directory sub directories

unmarshaller - ModuleFileUnmarshaller, needed to parse repo XML

Returns:

The directory containing the repo file and the parsed repo file (if exists)

Throws:

org.apache.ambari.server.AmbariException - if unable to parse the repository file

addServiceReposToOperatingSystemEntities

public static boolean addServiceReposToOperatingSystemEntities(List<RepoOsEntity> operatingSystems,
                                                               com.google.common.collect.ListMultimap<String,RepositoryInfo> stackReposByOs)

Checks the passed operatingSystems parameter if it contains all repositories from the stack model. If a repository is present in the stack model but missing in the operating system entity list, it is considered a service repository and will be added.

Parameters:

operatingSystems - - A list of OperatingSystemEntity objects extracted from a RepositoryVersionEntity

stackReposByOs - - Stack repositories loaded from the disk (including service repositories), grouped by os.

Returns:

true if there were added repositories

getServiceRepos

public static List<RepositoryInfo> getServiceRepos(List<RepositoryInfo> vdfRepos,
                                                   com.google.common.collect.ListMultimap<String,RepositoryInfo> stackReposByOs)

Given a list of VDF repositorie and stack repositories (grouped by os) returns the service repositories. A repository is considered a service repo if present in the stack model but missing in the VDF (check is performed by repository name, per operating system).

Parameters:

vdfRepos - the repositories coming from a version definition

stackReposByOs - the repositories in the stack model (loaded from disks)

Returns:

A list of service repositories

asResponses

public static List<RepositoryResponse> asResponses(List<RepositoryInfo> repositoryInfos,
                                                   @Nullable
                                                   String versionDefinitionId,
                                                   @Nullable
                                                   String stackName,
                                                   @Nullable
                                                   String stackVersion)

Convert a list of RepositoryInfo objects to a lost of RepositoryResponse objects

Parameters:

repositoryInfos - the list of repository infos

versionDefinitionId - the version definition id

stackName - the stack name

stackVersion - the stack version

Returns:

a list of repository responses
