Add frontend and scheduler for Autotest
The attached tarball includes the new Autotest web frontend for creating
and monitoring jobs and the new scheduler for executing jobs. We've
been working hard to get these complete and stabilized, and although
they still have a long, long way to go in terms of features, we believe
they are now stable and powerful enough to be useful.
The frontend consists of two parts, the server and the client. The
server is implemented in Python using the Django web framework, and is
contained under frontend/ and frontend/afe. The client is implemented
using Google Web Toolkit and is contained under frontend/client. We
tried to use Dojo initially, as was generally agreed on, but it proved
to be too young and poorly documented of a framework, and developing in
it was just too inefficient.
The scheduler is contained entirely in the scheduler/monitor_db Python
file. It looks at the database used by the web frontend and spawns
autoserv processes to run jobs, monitoring them and recording status.
The scheduler was developed by Paul Turner, who will be sending out some
detailed documentation of it soon.
I've also included the DB migrations code for which I recently submitted
a patch to the mailing list. I've included this code because it is
necessary to create the frontend DB, but it will (hopefully) soon be
part of the SVN repository.
Lastly, there is an apache directory containing configuration files for
running the web server through Apache.
I've put instructions for installing a full Autotest server, including
the web frontend, the scheduler, and the existing "tko" results backend,
at http://test.kernel.org/autotest/AutotestServerInstall. I've also
created a brief guide to using the web frontend, with plenty of
screenshots, at http://test.kernel.org/autotest/WebFrontendHowTo.
Please let me know if you find any problems with either of these pages.
Take a look, try it out, send me comments, complaints, and bugs, and I
hope you find it useful!
