Constructor Details

#initialize(svnroot, options = {}) ⇒ SVN

Creates an importer which gets the source for the Subversion URL source. The following options are allowed:

:svnup

options to give to ‘svn up’

:svnco

options to give to ‘svn co’

This importer uses the ‘svn’ tool to perform the import. It defaults to ‘svn’ and can be configured by doing

Autobuild.programs['svn'] = 'my_svn_tool'

#has_local_modifications?(package, with_untracked_files = false) ⇒ Boolean

Returns true if the SVN working copy at package.importdir has local modifications

Parameters:

  • package (Package) —

    the package we want to test against

  • with_untracked_files (Boolean) (defaults to: false) —

    if true, the presence of files neither ignored nor under version control will count has local modification.

Returns:

#status(package, only_local = false) ⇒ Package::Status

Returns status information for package

Given that subversion is not a distributed VCS, the only status returned are either Importer::Status::UP_TO_DATE or Importer::Status::SIMPLE_UPDATE. Moreover, if the status is local-only, Package::Status#remote_commits will not be filled (querying the log requires accessing the SVN server)

Returns:

  • (Package::Status)
