[Bug 1042231] Re: InstallPackageNames should not return until the package has been installed

[Brian Murray]

Hello Guillaume, or anyone else affected,

Accepted sessioninstaller into precise-proposed. The package will build
now and be available at
http://launchpad.net/ubuntu/+source/sessioninstaller/0.20+bzr128-0ubuntu1.2
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from
verification-needed to verification-done.  If it does not, change the
tag to verification-failed.  In either case, details of your testing
will help us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

  InstallPackageNames should not return until the package has been
  installed

Bug description:
  [ Description ]

  - Call the D-Bus method InstallPackageNames() to install some package
  - You are prompted asking if you want to actually install this package, accept
  - You are pompted asking for your admin pass, enter it
  - The InstallPackageNames method returns and the package is being installed

  This method should not return until the package has actually be
  installed. That's the easiest way for the application to know that the
  package is now ready to be used. That's also how it's implemented in
  the official implementation of PackageKit.

  [ Development fix ]

  r132 in lp:sessioninstaller

  [ SRU fix ]

  identical

  [ Test case ]

  1. Remove some GStreamer plugin by executing `sudo apt-get purge --yes gstreamer0.10-plugins-ugly && sudo apt-get autoremove --purge --yes`.
  2. Execute the command `python /usr/share/pyshared/sessioninstaller/gstinstaller.py "gstreamer|0.10|totem|Advanced Streaming Format (ASF) demuxer|decoder-video/x-ms-asf"`.

  [ Regression potential ]

  The most likely way this will break is to make the
  InstallPackageNames() function return at an inappropriate time. Check
  that it is synchronous, that it doesn't return until the package is
  installed.
