#873 Local Online Status Updates Slowly

[Alexander Jakobi]

Description

When loosing the network connection (e.g. unplug network) while being connected to an XMPP server, it takes around 30 seconds for the local internal connection status to be updated.
During this time, it is still possible to start a session initiation (which in the end fails).

Reproduction

• Have an (developer) IDE running Saros with an active connection to the XMPP server
• Switch off your network
• In the log window of the parent IDE, note that after approximately 30 seconds the internal connection state is set to NOT_CONNECTED
• Before the status change, you can still start a session initiation from the Saros panel, HTML GUI and project structure view

Expected Behaviour

The local connection state should be reliably identified. Actions that require a network connection can't be choosen to perform.

What is the point of adding such an bug entry ? Almost all non critical software applications will fail such badly if you unplug the network device during normal operation.

[Franz Zieris]

See "expected behavior".

[Stefan Rossbach]

There is already a Ping implementation in Smack, but guess what. Most servers are not supporting them. Why ? Because you are flooding the server with messages.

There is really NO way to detect network errors of such states in a timely manner.

And really ? Beside WIFI, who unplugs his/her network cable ?

"Private" means "only logged in user may read this ticket"

[Stefan Rossbach]

As nobody will ever implement the "Expected Behaviour" and this scenario is not common, to be more specific unrealistic -> who cares.
