A dpkg-based distribution.

Instance Methods

__init__(self, dpkg_status)
x.__init__(...) initializes x; see help(type(x)) for signature

source code

get_package_info(self, package, factory)
Get information about the given package.

source code

fixup(self, package, impl)
Some packages require special handling (e.g.

source code

installed_fixup(self, impl)
Called when an installed package is added (after fixup), or when installation completes.

source code

[zeroinstall.support.tasks.Blocker]

fetch_candidates(self, master_feed)
Collect information about versions we could install using the distribution's package manager.

Class Variables
str	name = `'Debian'` the default value for Implementation.distro_name for our implementations

Method Details

init(self, dpkg_status)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Parameters:

dpkg_status (str)

Overrides: object.__init__

get_package_info(self, package, factory)

source code

Get information about the given package. Add zero or more implementations using the factory (typically at most two will be added; the currently installed version and the latest available).

Parameters:

package (str) - package name (e.g. "gimp")
factory - function for creating new DistributionImplementation objects from IDs

Overrides: Distribution.get_package_info

fixup(self, package, impl)

source code

Some packages require special handling (e.g. Java). This is called for each package that was added by get_package_info after it returns. The default method does nothing.

Parameters:

package (str) - the name of the package
impl (zeroinstall.injector.model.DistributionImplementation) - the constructed implementation

Overrides: Distribution.fixup

installed_fixup(self, impl)

source code

Called when an installed package is added (after fixup), or when installation completes. This is useful to fix up the main value. The default implementation checks that main exists, and searches Distribution.system_paths for it if not.

Parameters:

impl (zeroinstall.injector.model.DistributionImplementation)

Overrides: Distribution.installed_fixup

fetch_candidates(self, master_feed)

source code

Collect information about versions we could install using the distribution's package manager. On success, the distribution feed in iface_cache is updated.

Parameters:

master_feed (zeroinstall.injector.model.ZeroInstallFeed)

Returns: [zeroinstall.support.tasks.Blocker]

a tasks.Blocker if the task is in progress, or None if not

Overrides: Distribution.fetch_candidates
