I have been looking into the NetworkProcess code that has recently been
added to WebKit2. For Qt we are considering moving all the networking into
a separate thread within the UIProcess.
Do you guys think that the NetworkProcess code could be designed in a way
to allow running in a separate thread of the UIProcess instead of in a
We are convinced that this design would be a very good fit for our needs.
Also in the light of the currently ongoing effort of cleaning up our
Qt-bits and pieces in WebKit2.
After a quick look it seems to me that this could be achieved with fairly
* Instead of relying on RunLoop::main() within NetworkProcess, a different
function would need to be introduced to retrieve a "networking RunLoop".
This would allow to process networking related events in the network
thread. Depending on the platform, this could of course return a pointer to
the main-RunLoop, for the cases where networking is indeed executed in a
* Splitting the NetworkProcess class in two pieces. The child process and
IPC setup remaining in NetworkProcess, and the actual networking code in a
separate class (e.g. called NetworkThread).
Provided the IPC (between threads in our case) would be setup upfront this
would allow running the code provided by NetworkThread in a separate thread.
Would patches aiming such a direction generally be accepted?
