Development Console - Datastore Error

[Tony Smith]

Hi,

I just upgraded to GoogleAppEngine_1.1.3 and when I go into the
Development Console/datastore I get these errors.
I only get them if I have something in the Datastore. I tried deleting
everything and recreating and I still get these errors. If I don't
have anything in the datastore, then I get a regular page saying that
I need to create the entities before viewing them.
Is it a bug in the latest release?

Thanks,
Tony

float('-inf') works on Linux/OS X but not on Windows, this was
probably not noticed during testing. Please try again after changing
datastore_file_stub.py like this:

old:
value_pb.set_doublevalue(float('-inf'))

new:
value_pb.set_doublevalue(-1e300000)

If this works it might be worth to file a bug...

Hi Tony,

This specific line of code wasn't changed from 1.1.2 to 1.1.3, so I think something more may be going on here.  Can you provide the data model you are using and the type of data being stored so that I can try to replicate the issue?

Also, what version of Windows and Python are you using?

Thanks,
Marzia

I'm having the same issue since upgrading to 1.1.3 (from 1.1.0).
Windows XP Pro, Python 2.5.2.

Hi,

I believe that Karsten had it right, please implement his workaround.

Thanks,
Marzia

Yup, that fixes it. I'm going to add a little extra explanation to
help others who have this problem search for this thread.

It appears that the problem only occurs when you have a model with
floating point values and/or Point values. When this is the case, any
attempt to load the Development console will get a Python error. There
are three lines in datastore_file_stub.py that should be changed,
replacing "float('-inf')" with "-1e300000".

No idea why this didn't cause a problem earlier, but in my own case,
it's possible I hadn't used the console since adding float values to
my model.

-Roy.

Thanks,

I followed Marzias recommendation, and changed the line, (also deleted
the pyc file) and restarted the local server and it now I can view my
admin console again.
I'm running win XP.
