Member Function Documentation

void cupt::system::Worker::changeSystem

(

const shared_ptr< download::Progress > &

progress

)

Modifies the system to achieve the desired state set by setDesiredState.

Parameters:

progress

void cupt::system::Worker::deleteArchive

(

const string &

path

)

Deletes an archive file (it may be a symlink). Verifies that deleted file is located under archives path directory.

Parameters:

path	absolute (i.e., not relative) path to file

shared_ptr< const ActionsPreview > cupt::system::Worker::getActionsPreview

(

)

const

Shouldn't be called before setDesiredState.

Returns:

a set of actions to get the desired system state divided by action types

vector< pair< string, shared_ptr< const BinaryVersion > > > cupt::system::Worker::getArchivesInfo

(

)

const

gets available archives of binary versions

Gets paths of all '.deb' archives in the archives directory and matches them to available binary versions. Not matched paths with be paired with an empty pointer.

Returns:

array of pairs < package name, pointer to binary version >

pair< size_t, size_t > cupt::system::Worker::getDownloadSizesPreview

(

)

const

Shouldn't be called before setDesiredState.

Returns:

pair: total amount of needed binary archives (in bytes), amount to download (in bytes)

map< string, ssize_t > cupt::system::Worker::getUnpackedSizesPreview

(

)

const

Shouldn't be called before setDesiredState.

Returns:

map: package name -> unpacked size change (in bytes)

void cupt::system::Worker::removeSnapshot	(	const Snapshots &	,
		const string &	name
	)

Removes a system snapshot.

Parameters:

name	name of the snapshot

void cupt::system::Worker::renameSnapshot	(	const Snapshots &	,
		const string &	previousName,
		const string &	newName
	)

Renames a system snapshot.

Parameters:

previousName	previous snasphot name
newName	new snapshot name

void cupt::system::Worker::saveSnapshot	(	const Snapshots &	,
		const string &	name
	)

Makes a system snapshot with a name name.

Parameters:

name	the snapshot name.

void cupt::system::Worker::setAutomaticallyInstalledFlag	(	const string &	packageName,
		bool	value
	)

Marks a package as automatically or manually installed.

Parameters:

packageName
value	if true, marks as automatically installed, if false, marks as manually installed

void cupt::system::Worker::setDesiredState

(

const Resolver::Offer &

offer

)

Sets the desired system state.

May be called several times for examining different possible system states.

Parameters:

offer

void cupt::system::Worker::updateReleaseAndIndexData

(

const shared_ptr< download::Progress > &

progress

)

Downloads latest Release and Packages/Sources files from repository sources.

Parameters:

progress
