The current milestone can be found on the roadmap page.

Generic Regression Testing Issues

  • Python versions: we support Python 2.4 to 2.7 (ie: CentOS5.x for old versions of python) - code that is not backwards compatible can sometimes make it into the repository (ie python syntax: r2616, r2615, r2608, r1280, r991, r990), simply compile-testing it is often enough to spot those, other issues may affect packaging (ie: #116) which means testing beta package builds, other bugs can be more difficult to identify and even more difficult to fix (ie: #251, #215). We also want to check that the Python 3.x version can be built (compile tested), though actually using/testing it is not required at present since it isn't officially supported.
  • gtk/pygtk versions: similar to Python, older versions (ie: 2.17 and older) can sometimes cause problems (ie: r1498, r555, r554).
  • client applications: it is important to test a wide range of client applications, using a wide variety of UI toolkits and languages: gtk, qt/kde, wx, Java (see #162), etc.. Each can uncover subtle bugs. Then there are specific applications that are known to cause problems because of the way the interact with the X11 server: wine applications?, VMWare? (#199), Firefox? (#220, #158, #96), etc. Also, newer versions of specific target applications may change the behaviour of the application in ways which have a significant impact on xpra compression/quality.
  • backwards compatibility with old versions: we try to keep backwards compatibility with older versions as much as possible, though some features may not be available. Occasionally we will drop compatibility (ie: #57) to allow the code to move on from old crufty workarounds. At present, all versions from 0.3.11 onwards should be able to connect, both as client and server.
  • unusual setups: although these may not be optimal, people still expect this to work - and it should! Again, the errors that this uncovers may well help in other areas. Things like: running xpra nested (#210), running xpra from "ssh -X" / "ssh -Y" (#207, #3)
  • platform specific quirks: OSX problems (#249), platforms with static builds of the x264 and vpx libraries or those where the dynamic libraries are bundled in a binary image (#103): MS Windows, OSX, CentOS 5.x, CentOS 6.x, Debian Squeeze, Ubuntu Lucid)
  • binary builds with library updates (OSX and MS Windows), in particular: gtk-osx updates and rebuilds, pycrypto, gstreamer, pywin32, etc..

Specific Testing Combinations

The release notes should help in figuring out what has changed and therefore what is likely to require more thorough testing. Here are some of the most common setups, and those that are most likely to uncover compatibility issues. Ideally, all of those should be tested before major releases.

  • All MS Windows clients (from XP to 8) with CentOS/RedHat 5.x and 6.x servers
  • OSX clients
  • CentOS 5.x clients with both old servers (CentOS 5.x) and new ones (Fedora 18+ or Debian sid)
  • Debian Squeeze or Ubuntu Lucid packages.
