[Paraview-developers] Casual Weekend Read: ProcessModule 2.0

[Moreland, Kenneth]

My notes:


 *   Why does vtkProcessModule have to init functions that must be call sequentially?  Why not just have one initialization function?
 *   Can the client call AcceptConnectionsOnPort?  Is that for reverse connections?  The documentation that this class is to establish a service.
 *   The connections methods talk about sockets & TCP/IP.  What about other connection types like SSL, HTTPS, MPI, or Portals.  They come up.
 *   How does vtkConnection establish itself with a socket connection managed by the vtkProcessModule?
 *   I find logging a bit overrated.  I find I would usually rather have synchronous client/server communication where if the server is stopped the client blocks on the last call that initiated the server.

Folks,

In line with the ServerManager 2.0 documentation, here's another wiki
summarizing proposed changes to vtkProcessModule. Besides simplifying
and cleaning up, these changes will make it easier to do the
following:

* Create/Manage additional socket connections between processes with
custom protocols
* Bi-direction messaging i.e. send messages from server-to-client (of
course protocol will have be defined as such and client will have to
monitor activity periodically).

Here's a link to the Wiki page:

[ Sorry Yumin, no diagram still :). ]

As with ServerManager 2.0 proposal, none of these changes are expected
to affect ParaView master for a quarter or two. We'll keep everyone
posted. Again, this is early design, so feel free to voice your
concerns and suggestions and we can try to address them in the
implementation.
