[google-appengine] Re: Inconsistency between dev_server and production server on sharded counter behaviour.
If you have different behavior on dev_appserver and the production server you should file a bug report in the issue list http://code.google.com/p/googleappengine/issues/list At least dev_appserver should report the transaction problem the same as production. dev_appserver has code to check for multiple entity groups but it might miss your situation. (if you find the bug yourself, don't mention the solution in the issue report, it won't be part of dev_appserver unless you sign an agreement, then we have to patch dev_appserver ourself each time there is a new version) 2009/2/7 Qian Qiao qian.q...@gmail.com: The code in my original email worked in dev_appserver, which I suppose is incorrect. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Again *major* server errors of app engine!
I think our app was running into this issue also. We are using our own django and parts of the appengine helper patch. I would see 500 errors, deadlineexceeded but the exception is thrown in the django, helper or pyamf (in our case we use pyamf to process the requests from a flex/flash client) code which was even before any datastore operations or much else ran. The question is. How do you set it up so that django/helper are cached imports? If you import things in main.py (where our main method is) does that keep things in memory? The docs seem to be pretty light on details about how to do this. -Mike On Feb 8, 3:19 am, conman constantin.christm...@googlemail.com wrote: Davel63, are you also using appengine patch?

[google-appengine] Re: Django 500's and Error Reporting
It didn't work for me, but gave me a clue. As part of experiment, I deleted the DEBUG=True line from settings.py, and the stack trace did start appearing in the Console window. True, it was complaining about not having an error template, but it also showed me the actual cause of the originating error. Progress! Back under the original, correct settings, I stepped through the process of raising an error, and at line 131 in debug.py the system raises an exception while raising an exception. That's why I get the silent 500 failure. On almost anything: missing variable, undefined member function, datastore put missing a required value, etc. In some circumstances it does, work though! Any ideas as to how to get stack traces to show up reliably in the browser, or even just print on the console?

I'm seeing this, too: large number of DeadlineExceededErrors and other errors at the same times of the day, for the past several days. I'm not sure it's related to Django or anything else. We are using Django and pyamf, and the errors will happen anywhere. I think it's just the Django and pyamf have a lot of initialize code to go through, so the errors that happen randomly often happen in there.

We are using Django v0.96, which is included with GAE (so, not the Patch, but not webapp either). Nick Winter's comment could be right ... maybe it's not Django, but Django just has a lot of initialization code.
