Boom (tried several VM always crash) PharoDebug.log attached I've uploaded an image here: http://lolgzs.free.fr/pharo/PharoZnCrash.zip Attachments: PharoDebug.log 140 KB _______________________________________________ Pharo-bugtracker mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-bugtracker |
Comment #1 on issue 4910 by [hidden email]: Reproducible crash with Pharo 1.3 + Zn http://code.google.com/p/pharo/issues/detail?id=4910 Laurent, OK, I downloaded your image and on my mac with my vm it just hangs. What version of Zn are you using ? In the lastest version, you should see this: ZnMultiThreadedServer(ZnSingleThreadedServer)>>readRequest: ^ [ self readRequest: stream ] on: (self exceptionSet: #(ConnectionClosed ConnectionTimedOut ZnParseError PrimitiveFailed)) do: [ :exception | self log debug: [ exception printString, ' while reading request' ]. nil ] On PrimitiveFailed, things should be cleaned up properly. You should also be using the latest Pharo images with the fix to the Semaphore problem: http://code.google.com/p/pharo/issues/detail?id=4768 I have no time to rebuild your image right now. Thanks for reporting this. Sven _______________________________________________ Pharo-bugtracker mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-bugtracker |

Comment #3 on issue 4910 by [hidden email]: Reproducible crash with Pharo 1.3 + Zn http://code.google.com/p/pharo/issues/detail?id=4910 I would really like to solve this problem. I have described it before, but here is what I think happens: - you start the ZnZincServerAdaptor, which implies creating a listener socket and process - you test it to see if it is running by doing one or more requests - this means that at least one connection and worker process are alive - you save the image - the server receives a shutdown and stops cleanly - since this is a ZnMultiThreadedServer and not the experimental ZnManagingMultiThreadedServer it leaves the connection and the worker process alone - you restart the image - the server receives a startup and starts working - the worker process is revived and will continue its blocking read for the next request - this signals a primitive failed and causes a hang/crash Now, using the lastest Zn, the primitive failed should be caught and the connection and worker should be cleaned up silently, unless there is also a VM problem, but I don't think so. (It would also be possible to make sure that no open connections are alive, close the browser that you used, check the Process Monitor) Another option is to use the experimental ZnManagingMultiThreadedServer which does track its own connections and cleans them up, which should result in the worker processes stopping cleanly. The next code requires the very latest Zinc-Seaside adaptor, you could try: ZnZincServerAdaptor new port: 8080; serverClass: ZnManagingMultiThreadedServer; start; yourself But then you absolutely need this patch: http://code.google.com/p/pharo/issues/detail?id=4768 _______________________________________________ Pharo-bugtracker mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-bugtracker |

Comment #5 on issue 4910 by [hidden email]: Reproducible crash with Pharo 1.3 + Zn http://code.google.com/p/pharo/issues/detail?id=4910 Laurent can you have a look if this is still a problem with the latest 14228 pharo because we integrated the latest version of Zn. _______________________________________________ Pharo-bugtracker mailing list [hidden email] http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-bugtracker |
