my app suddenly shows an error! yesterday, everything OK

[manuelaraoz]

All of a sudden, a page in my app stopped functioning
This is weird, as I have not deployed anything new, and it was working
great yeasterday...

Could it be an internal change that drove to this error?

A web page in my app doesn't load... it's handler is practice.py
it uses an access to datastore, where it fails..
I can't seem to understand where the error comes in order to prevent
it!
Can anyone help? thanks in advance.. :D

This is the traceback:
Traceback (most recent call last):

I'm using a custom Query class called BookmarkQuery
everything was working quite OK with it until today (the error seems
to be related to it)

any ideas of why this is happening?
I repeat, the error appeared out of nowhere... yesterday my app was
working perfectly
Thanks!

hi manuel! we pushed a new version of our API code to production
recently in preparation for an upcoming release, which has caused
problems for people who use forked versions of some of our API code,
like the problem described in
http://groups.google.com/group/google-appengine/browse_thread/thread/8e9267e3c9346317
, or code that reaches below our API layer, which it sounds like
BookmarkQuery does.

i don't have the BookmarkQuery source, so i don't know the exact fix
you need, but the problem stems from a new optional keyword argument
that we added to the Query classes' constructors. try adding a
keys_only=None parameter to BookmarkQuery's constructor and see if
that helps.

[Manu]

the code for BookmarkQuery is here:
http://bitbucket.org/moraes/appengine/src/422cc9b9473b/bookmark.py


I'm using it but haven't developed it myself, so I don't really know
how it works.
Please help me, isn't there a way to quickly fix this at least for the
moment?
Thanks in advance!

Hi Manu,

For now you can get things working again by replacing lines 36 and 37
of bookmark.py with this:
---
def __init__(self, kind, filters={}, _app=None, keys_only=False):
super(BookmarkQuery, self).__init__(kind, filters, _app, keys_only)
---

-Nick Johnson

[Manu]

Hi!

Thanks a bunch!
That fixed all :D:D:D

Will that work after the upcoming release?
Can I ask you (if you have time, tell me, if not, no problem)
why was that failing? I'd really like to understand a little more.

Also, I'd like to understand how all of this BookmarkQuery works...
I'll have to read the source and learn a bit
Thanks for your time!

I just upgraded to version 1.2.2 and I'm getting a similar error:

I'm not using BookmarkQuery, so how do I fix this???

Please help!

[Jason (Google)]

Were you prompted to update within GoogleAppEngineLauncher or did you manually choose to update by selecting "Check for Updates" in GoogleAppEngineLauncher's Help menu?

[Kwame Iwegbue]

I was prompted to update it. However the problem resolved after I restarted the JVM.

[Rodrigo Amaral]

I'm getting a slightly different error. My application behaves like
the API had not been upgraded yet, but the Query object is called in
the "new" way. Please note that the only thing I do in this case is to
call the all() method of the model. Here's the traceback:

Do you guys have any clue?

Hello, Ryan

My application is also broken, but shows a slightly different error.
I'm not using any fork of the Query class. Here's the log:

Do you guys know a way to workaround this one?

Thanks in advance!

[Kwame]

I had a similar problem after upgrading to v 1.2.2
first I tried to roll back the update but I was unable to, but somehow
the issue resolved after I restarted my computer.

hope that helps

[Rodrigo Amaral]

The application works fine on localhost. This problem only shows up
after deploy. It looks like the API version of the production
environment had not been upgraded yet. It's a really weird situation
and I can't figure out how to fix it.

Suggestions are welcome. Thanks!
