NAME

VCI::VCS::Bzr - Object-oriented interface to Bazaar (bzr)

SYNOPSIS

 use VCI;
 my $repository = VCI->connect(type => 'Bzr',
                               repo => 'bzr://bzr.example.com/');

DESCRIPTION

This is a "driver" for VCI for the Bazaar version-control system. You can find out more about Bazaar at http://bazaar.canonical.com/.

For information on how to use VCI::VCS::Bzr, see VCI.

CONNECTING TO A BZR REPOSITORY

For the repo argument to "connect" in VCI, choose the directory above where your branches are kept. For example, if I have a branch http://bzr.domain.com/bzr/branch, then the repo would be http://bzr.domain.com/bzr/.

Bzr's connect also takes one optional extra argument:

x_bzr

The path to the bzr binary on your system. If not specified, we will search your PATH and throw an error if bzr isn't found.

Taint Mode: VCI will throw an error if this argument is tainted, because VCI just runs this command blindly, and we wouldn't want to run something like delete_everything_on_this_computer.sh.

REQUIREMENTS

VCI::VCS::Bzr requires that the following be installed on your system:

bzr

bzr Must be installed and accessible to VCI. If it's not in your path, you should specify an x_bzr argument to "connect" in VCI, which should contain the full path to the bzr executable, such as /usr/bin/bzr.

bzrtools

The bzrtools extension package must be installed. Usually this is available as a package (RPM or deb) in your distrubution, or you can download it from here: http://launchpad.net/bzrtools.

bzr-xmloutput

Because VCI::VCS::Bzr processes the output of bzr, it needs it in a machine-readable format like XML. For bzr, this is accomplished by the bzr-xmloutput plugin, which is available here: http://launchpad.net/bzr-xmloutput.

You can read about how to install it at http://doc.bazaar.canonical.com/plugins/en/plugin-installation.html.

This is in addition to any perl module requirements listed when you install VCI::VCS::Bzr.

LIMITATIONS AND EXTENSIONS

These are limitations of VCI::VCS::Bzr compared to the general API specified in the VCI::Abstract modules.

VCI::VCS::Bzr::Repository

projects

On some repositories, "projects" will return an empty array, even though there are branches there. This only happens for repositories where we can't list the directories. For example, HTTP repositories without a directory listing.

However, get_project will still work on those repositories.

VCI::VCS::Bzr::Directory

When constructing a Directory, you cannot specify time or revision without also specifying contents. VCI::VCS::Bzr itself never does this, so you generally don't have to worry about this unless you're building your own objects for some reason.

PERFORMANCE

With local repositories, VCI::VCS::Bzr should be very fast. With remote repositories, certain operations may be slow, such as calling projects on a Repository.
