Summary: update trick_comm_library to discard corrupted data

Created: 2009–10–08 11:40

Status: Released

Category: Request

From: frankie

Version: 2.0

Released_In: 2.1

Description:

right now, the variable server interface library calls the user callback when data is received. This is a request to upgrade the internals so that the user receive callback is only called if the number of variables in the received data matches the number requested by the client.

For example, sometimes the variable server can send the first packet of data for the variables requested before the client has a chance to fully request the complete list of variables it needs. In this case, the data needs to be discarded. Sometimes, you will see this manifested by a tcl error when you startup since it is expecting to process data that isn't there.
