Re: [tcf-dev] Multiple TCF debug sessions

Hi Eugene,

 

Thanks for the quick answer.

 

Can be that the Eclipse Client is confused by the duplicated Hello events our Agent (wrongly) sends to the Eclipse Client when the second session starts?

 

10:10:46.7661135 TCF Recv E Locator Hello ["Diagnostics","Locator","ZeroCopy"]

10:10:46.7664954 TCF Sent E Locator Hello ["Locator","Streams","Expressions","Memory","Processes","Registers","RunControl","Breakpoints"]

10:10:46.7670834 TCF Sent E Locator Hello ["Locator","Streams","Expressions","Memory","Processes","Registers","RunControl","Breakpoints"]

 

Looks to me that this can be root cause of this strange behavior.

 

Thanks,

Daniel

Hi Daniel,

 

> Eclipse then sends two Processes.start commands over the new connection.

 

This looks wrong and I don’t see it with open source agent for Linux - multiple debug sessions work fine.

I don’t see anything in the code that could send a second Processes.start command.

This is, probably, something specific to your implementation.

You need to debug the launch code to see why second Processes.start is sent.

 

Regards,

Eugene

Hi All,

 

We are observing some strange behavior in Eclipse, when starting a second TCF debug session, while there is already a debug session active.

 

The trace below shows this problem.

 

At 10:10:14.2369669 the first debug session is started.

Eclipse sends the Hello event, sends some other commands and starts the process by the Processes.start command.

(In the trace the Hello response comes after the subscribe commands, but this is because we trace the outgoing communication asynchronously after the send operation is really completed and there probably was a thread switch)

 

At 10:10:46.7621122 the second debug session is started by clicking the bug button.

Eclipse opens a new TCP connection and sends the Hello event.

Our agent responds with Hello on each channel.

 

Eclipse then sends two Processes.start commands over the new connection.

This initializes two new debug session objects within out agent. For the two new started projects.

 

The eclipse window, which showed one debug session until now, now shows the two new debug sessions, but not the old one.

The old debug session is not visible any more.

The old debug session was not terminated and there is now no way to terminate it, because is not visible any more.

So it is still blocking physical resources (COM port).

 

The question is, why the old debug session is abandoned and two new are started?

Other question is, why a new connection is created, when the same type of debug configuration is used and the capabilities of the agent are already known (Hello).

For the second session, we see that Eclipse is able to send two Processes.start  commands over one connection.

 

Addition info:

-    When now a new debug session is started, the existing two are abandoned and three new are started.

-    Sent means Agent did send

-    Recv means Agent did received
