Pharo responseless when debugger steps into DNU in Seaside app
 
|
Hi everyone,
I'm getting a problem debugging Seaside applications in latest Pharo. When stepping with the debugger through the execution of a seaside application and encountering a message not understood, the entire Pharo system freezes and is totally unresponsive. It does not show that a DNU occurs, it simply becomes unresponsive when trying to step over the message that does not exist. I have to force quit. The problem can easily be recreated by changing a seaside component's render method such that a DNU occurs. Next, choose to debug the problem and restart the context. Now start stepping through the method and the system freezes when you try to step into the message that is not understood. The system freezes and does not show you a DNU. It seems to be a Pharo-Seaside problem since I do not have the same problem when doing this outside of Seaside applications. I'm using Pharo 09.7.5 (with seaside) and did a system update just now. I'm trying to drill down to the source of the problem but if anyone has any ideas.... ---------------------------- Johan Brichau [hidden email] _______________________________________________ Pharo-project mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project |

Thanks this is important. Can you open a bug entry report? I go some problem with the system not been able to spawn a debugger but I was waiting to get the beta version.

What version of Seaside is this?
There are several debugger related bugs in Seaside 2.9a4: <http://code.google.com/p/seaside/issues/list?q=debugger>.

The additional info is in the bug report (1038). It seems the DNU is handled by Seaside code since it pops up in the browser (as it normally does). However, you cannot do anything beyond that point... ---------------------------- Johan Brichau [hidden email] _______________________________________________ Pharo-project mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project |

Hi Lukas,
No, this is Seaside2.8a1-pmm.593 (which is included in the Pharo download image) On 05 Aug 2009, at 10:01, Lukas Renggli wrote: > What version of Seaside is this? > > There are several debugger related bugs in Seaside 2.9a4: > <http://code.google.com/p/seaside/issues/list?q=debugger>. > > Lukas > > 2009/8/5 Stéphane Ducasse <[hidden email]>: >> >> On Aug 4, 2009, at 8:33 PM, Johan Brichau wrote: >> >>> Hi everyone, >>> >>> I'm getting a problem debugging Seaside applications in latest >>> Pharo. >>> >>> When stepping with the debugger through the execution of a seaside >>> application and encountering a message not understood, the entire >>> Pharo system freezes and is totally unresponsive.

I managed to trace the problem to the following:
After rendering the stack trace of the DNU in the browser, the EscapeContinuation terminates the thisContext and unwinds the stack. After this, the execution resumes in the #withEscapeContinuation: method, essentially ending up executing "Processor terminateActive" in the bottom stack frame (execution record of #newProcess), upon which the system freezes. If you execute all code just up to the "Processor terminateActive", you can again hit the debug link in the browser to open a debugger with the DNU.
