NAME

       org.debian.apt.transaction - the main interface of an aptdaemon transaction

SYNOPSIS

       Each  transaction  is  represented  as  an  unique  D-Bus  object,  e.g. at the D-Bus path
       /or/debian/apt/transaction/12123-123-123213.  Which provides the following interface.

DESCRIPTION

   METHODS
       ProvideMedium
              ProvideMedium  (in 's' medium)

              Continue a paused transaction which is waiting for the given medium.

              If a media  change  is  required  to  e.g.  install  packages  from  a  CD/DVD  the
              transaction  will  be paused and the RequiredMedium property changed to an array of
              the medium label and its mount point.  Furthermore the MediumRequired  signal  will
              be emitted.

       ResolveConfigFileConflict
              ResolveConfigFilePrompt  (in 's' config,
                                  in 's' answer)

              Continue  a  paused  transaction  which  is  waiting  for  an  answer  to  handle a
              configuration file conflict.  Config is the path to the current configuration  file
              and answer can be either "replace" or "keep".

              If  a  later  config  file  is  shipped  in  a  package  which  overrides some user
              modifications the transaction will be paused and the ConfigFileConflict property of
              the transaction will be set to an array of the old and new configuration file path.
              The  later  one  is  supposed  to  replace  the  former   one.    Furthermore   the
              ConfigFileConflict signal will be emitted.

       Simulate
              Simulate  ()

              Simulate  the  transaction  and  calculate  dependencies,  required  disk space and
              download size. If a transaction would fail the corresponding error will be raised.

       Run    Run  ()

              Queue the transaction for processing. Afterwards there cannot be made  any  further
              changes to the transaction, e.g. modifing the http proxy.

       Cancel Cancel    ()

              Cancel the transaction if possible.

   SIGNALS
       Finished
              Finished  ('s' exit_state)

              The  signal will be emitted when the transaction has been processed. The exit_state
              indicates if the transaction was completed, cancelled or failed.

       MediumRequired
              MediumRequired ('s' label,
                             's' mount_point)

              The signal will be emitted if the transaction has been paused and waits for a media
              change to install packages.

       ConfigFileConflict
              ConfigFileConflict  ('s' old,
                             's' new)

              The  signal  will  be  emitted  if  the  transaction  has been paused because a new
              configuration file is shipped in a package which would override changes by the user
              in the old configuration file.

       PropertyChanged
              PropertyChanged     ('s' property_name ,
                             'v' value)

              The signal will be emitted if one of the following properties has changed.

   PROPERTIES
       The  properties of the transaction are available through the Get And GetAll methods of the
       D-Bus properties interface and can be changed using the Set method.

       Role read 's'
              The role enum of the transaction, e.g. update-cache.

       Status read 's'
              The current status enum of the transaction, e.g. downloading

       StatusDetails read 's'
              A clear text message describing the current status.

       Progress read 'i'
              The progress of the transaction in percent.

       ProgressDownload read 'sssiis'
              The last download progress information recieved from APT. It is  an  array  of  the
              URI,  status  enum,  short  description,  full size, already downloaded size and an
              error or status message.

       Space read 'i'
              The additional disk space in Bytes which will be required by the transaction.   The
              Simulate method has to be called to calculate the download size.

       Download read 'i'
              The required download size in Bytes of the transaction.  The Simulate method has to
              be called to calculate the download size.

       Packages read 'a(a(s)a(s)a(s)a(s)a(s)a(s)a(s))'
              The lists of packages which are initially  queued  to  be  installed,  reinstalled,
              removed, purged, upgraded, downgraded or skipped from upgrading.

       Dependenciens read 'a(a(s)a(s)a(s)a(s)a(s)a(s)a(s))'
              The lists of packages which are additionally required to be installed, reinstalled,
              removed, purged, upgraded, downgraded or  skipped  from  upgrading.   The  Simulate
              method has to be called to calculate the dependencies.

       Cancellable read 'b'
              If the transaction can be cancelled.

       TerminalAttached read 'b'
              If  the  master  pty which has to be set using the Terminal property is attached as
              controlling terminal to the underlying dpkg call.

       RequiredMedium read 'a(ss)'
              The transaction will be stopped if a media change is required to install  packages.
              This property provides the label and the mount point of the requested medium.

       ConfigFileConflict read 'a(ss)'
              The  transaction  will  be  stopped  if a configuration file shipped in the package
              overrides changes of the user. This property provides the path to current  and  the
              path to the new configuration file.

       ExitState read 's'

              apt, e.g. de_DE@utf-8.

       Terminal read-write 's'
              The path to the master pty which will be the controlling terminal of the underlying
              dpkg call. This allows to have an interactive terminal session.

       DebconfSocket read-write 's'
              The  path  to  the  socket which will be used by the debconf passthrough backend to
              forward the debconf communication to the user session.

       Paused read 'b'
              If the transaction is paused, e.g. waiting for a conflict file resolution or  media
              change.

       Unauthenticated read 'as'
              List of unauthenticated packages which are going to be installed.

       RemoveObsoletedDepends read-write 'b'

              automatically should be removed too.

       AllowUnauthenticated read-write 'b'
              If it is allowed to install not authenticated software packages.

       HttpProxy read-write 's'
              The URL of an http proxy which should be used to download repository meta data  and
              package  files,  e.g.  http://myproxy.athome:8080.  You  should set the system wide
              proxy if you use this feature regularly.  MetaData read-write 'a{ss}'  A  dictonary
              which  allows  client  application to store additional data in the transaction. The
              key name has to include an identifier of the client  application  separated  by  an
              unterscore  from the key name, e.g. sc_icon for the application icon name stored by
              software-center. The property cannot be changed anymore after the  transaction  has
              been queued.
