Hi Xiang,
At this stage I'm not going to drop shared process code for the desktop, but I
do not except it can
happen in future. Shared process model makes Crosswalk much more complex, and
it was proved
that it does not give any performance benefit.
(Frankly, I do not think Crosswalk should try to provide things like task
scheduler or background sync on desktop).
As for the application persistent data removal, I think it is a valid point.
Further we'll need to provide command line interface (or/and UI) to do that.
BR,
Mikhail

Hi Mikhail,
Does this mean we will drop the service mode on desktop? If true, I'm
not sure how will some future APIs(like task scheduler, backgroun sync,
notification) be implemented without a system daemon manages these apps.
Also I think installation/uninstallation can make app ownership clearer.
For example, when we uninstall an app, its working data(like cookies,
local storage, scheduled tasks, sync) will be deleted too. Without
uninstallation if we removed a package file, we still need work out new
policy to retire its working data.
Regards,
Xiang
