Summary: support for reconnecting to a manager after a loss of connection

Created: 2011–05–13 10:06

Status: Released

Category: Request

From: frankie

Version: 2.2

Released_In: 2.3

Description:

currently, if the dcomm manager goes down, all clients have to be restarted.

this is a request to add code to the library such that clients can detect the failed connection with the manager, keep running, while polling for reconnection without blocking.

this would also require the manager to have some sort of restart logic to try and get the state as close to where it left off as possible.

Comments

frankie January 15, 2013, at 10:03 AM: This has been implemented, but the logic in the manager to try and restore the state on restart has not. The clients do poll for a new manager to come up and reconnect without blocking the scene updates.
