[google-appengine] Unexpected timeouts

[Roy Leban]

This might be bug 764 (http://code.google.com/p/googleappengine/issues/
detail?id=764) but I'm not sure.

Sometimes, I get timeouts that don't make sense. For example,
refreshing my home page (sometimes, when it happens to include a
single database write).

0-13 05:58PM 18.196 / 500 4180ms 10883mcycles 5kb

  File "myfile.py" ...
some_entity.put()
  File "/base/python_lib/versions/1/google/appengine/ext/db/
__init__.py", line 618, in put
return datastore.Put(self._entity)
  File "/base/python_lib/versions/1/google/appengine/api/
datastore.py", line 162, in Put
raise _ToDatastoreError(err)
  File "/base/python_lib/versions/1/google/appengine/api/
datastore.py", line 1627, in _ToDatastoreError
raise errors[err.application_error](err.error_detail)
Timeout

It's looking like the 10883 megacycles is 20-50x a typical load of my
home page. Anybody have any ideas?

[google-appengine] Getting 'UnicodeDecodeError'. Please help

[Nishu]

Hello,

I am trying to develop a screen scraping application using the google
Webapp framework. The application parses the html output of some other
page to extract the required data and then forms a string out of these
data. Sometimes the application works well but at times the
application raises the following error:

UnicodeDecodeError: 'ascii' codec can't decode byte 0x95 in
position 100: ordinal not in range(128)

After googling around for some time I tried the following:

sys.setdefaultencoding("UTF-8")

As a result the default encoding was set to 'UTF-8' but even this did
not solve the problem and now the application raised the following
error:

   UnicodeDecodeError: 'utf8' codec can't decode byte..

So please help me solve this problem. Thanking you in advance.

Nishant

[google-appengine] Re: Missing Applications

[Marzia Niccolai]

Hi Matt,

This is happening because you are using an account that is both a Google
Apps account and a Google Accounts account.  The system doesn't support this
combination well.

The easiest thing to do is to use a Google Accounts account if you plan on
using Google Accounts authentication (such as an @gmail account).  If you
are planning to use Google Apps authentication, choose an Apps account that
isn't also a Google Account.

Please follow up with me directly if you need help configuring this.

[google-appengine] Random HTTP 500 37315 - - errors

[phtq]

I have a PC program which sends HTTP requests to the GoogleAppEngine
in order to load the database for our project. The application works
fine using the PC based dev environment but when applied to the online
environment occasionally a request fails with error code 500 as shown
by the online log. The failure appears to happen without generating an
exception in the python code as the debug output inside the exception
handler never appears.

How do I debug this?

PS. The first few time this db upload was done online it also worked
fine. The problems just started appearing today.

[google-appengine] Re: Why my website is speeder using www. than without ?!?

[Barry Hunter]

Google have decided they can no longer support 'naked' domains, ie
without a www - mainly becuase naked domains cant work well with cname
records. And the technology they used to work around that limitation
itself has issues.

http://code.google.com/appengine/kb/commontasks.html#naked_domain


... so work at 'hosting' the naked domain elsewhere, and have it
simply redirect to the www record.

[google-appengine] Faster choices code

[Andy Freeman]

google/appengine/db/__init__.py starting at line 401 is:
  if self.choices:
match = False
for choice in self.choices:
  if choice == value:
match = True
if not match:
  raise BadValueError('Property %s is %r; must be one of %r' %
(self.name, value,
self.choices))

It could be:
  if value not in (self.choices or (value,)):
raise BadValueError('Property %s is %r; must be one of %r' %
  (self.name, value,
self.choices))

"not in" will stop when it finds a match and may be faster for each
element checked.

Note that making self.choices a set would make the "not in" test O(1).

Haven't seen it while paging through, but I've definitely had that
error when editing an entity -- both on the production server and the
local development server.  I've observed a weak correlation between
seeing the error message and having data in the Datastore that
violates model constraints (e.g., I altered the model and made a field
required that previously wasn't, but I have old data in the datastore
that have that field set to null).  In development, I've only been
able to solve it by blowing away my datastore, and in production it
seems to have resolved itself.

best,
- Fred.

Taking a look at the right side shows the letter "c" occurs in lots of
places unrelated to programming. It's probably true for c# and even c+
+, because search engines usually don't take punctuation into account.

Considering that python and java too have additional meanings I'd say
this trend graph is pretty much useless for comparing interest for
these languages.

[google-appengine] Re: Implement AJAX in App Engine

[Davide Rognoni]

"Ajax Requests"
http://docs.jquery.com/Ajax

"setInterval(func, interval, [args])"
Calls the specified "func" (or a JavaScript statement) repeatedly per
the "interval" interval, in milliseconds (ie: 1000=every 1 second).
"func" must be surrounded in quotations, as if it was a string. Use
the optional "args" to pass any number of arguments to the function.

[google-appengine] Re: Error Log?!

[Marzia Niccolai]

Hi,

With out more information, my first advice would be to check the settings in
your app.yaml.  It seems most possible that the URL you are hitting isn't
properly mapped to a system resource.

If you are still having issues, please post your app.yaml and some
description of the code/static content to which it maps.

[google-appengine] Re: datastore .order question

[yejun]

It will only pull unnecessary data when you use offset parameter in
fetch(limit,offset=0). Because when you set an offset, the datastore
still need to iterate all previous data before that offset.

[google-appengine] Re: datastore .order question

[David Wilson (entertainment cloud)]

when you say the same is not true of filter, are you saying that

Thing.all().filter('value >'  5).get()

will pull Things 1,2,3,4,5(like the offset issue) the records from the
datastore, but just return Things 6 from the query.

this seems wrong to me.

The reason im making sure on this is that my Thing has a large Blob in
it that i really need to make sure is not getting pulled apart from
the ones im displaying at the time. Otherwise i will split up the
model and put an id in the Thing to a new model ThingBlob.

Hi Joel,

I don't recall seeing an issue listing like this, so feel free to add
it to the issue tracker: http://code.google.com/p/googleappengine/issues/list

Thank you,

[google-appengine] Re: BaseModel IndexError: list index out of range

[ghostrocket]

this is the issue:

line  51 of appengine_dango/models.py is:

self.app_label = model_module.__name__.split('.')[-2]

i'm not sure why we need the ".split('.')[-2]" but my model_module is
not returning a string with a '.' in it. any idea if this is a bug or
did i misconfigure something?

[google-appengine] Re: decision to be an API and not a protocol...

[Peter Recore]

App engine to me is a hosting environmnt first, and an API second.
The API alone is no big deal. In fact, it has some annoying
limitations that many other api's don't. (I'm not complaining here)
App engine's killer feature is the fact that it is hosted within
google's infrastructure, with the ability to scale up by adding lots
of instances of your app automagically.

The challenge of implementing other languages, as I understand it, is
figuring out how to sandbox them, and bring up / take down instances
at will.

[google-appengine] Re: Avg CPU: 6206 /!\

[Josh Heitzman]

Yeah, my requests seem to be taking about 4-6k megacycles longer to
process today then they were two days ago.  In some cases this is 100%
longer and in others its only about 35%  Interestingly my root page is
still down around 30 megacycles, so it seems that the code needs to do
certain things to be afflicted.

[google-appengine] Re: datastore .order question

[Marzia Niccolai]

Hi,

The same is not true of filter().  Filter will start at the first value
larger than x, and should be used if you want to paginate your records.

Brett Slatkin's IO talk covers scalable pagination recipes, and I suggest
checking it out:

[google-appengine] BaseModel IndexError: list index out of range

[ghostrocket]

Hi All -

This is driving me crazy, any help is greatly appreciated. The
following:

class MyModel(BaseModel):
title  = db.StringProperty(required=True)

and

stuff =MyModel(title="mytitle")

yields "IndexError: list index out of range"

but extending db.Model instead of BaseModel works just fine. What
gives?

[google-appengine] 3000 mcycles and This request used a amount of CPU and may soon exceed its quota

[Matija]

Hi,
I have some init stage imports to app-engine application and
combining  with some ajax calls I was able to use maximum of 3000
mcycles per request. When there is request that consumes more the 1000
mcycles I have warning 'This request used a amount of CPU and may soon
exceed its quota.' in my application log.

Should I be worried because of that or not. Is this general warning
for me to inform me that with this average CPU use i will use all my
CPU quota eventually soon, or that app-engine quota permits this CPU
usage only few times let's say per minute and that they will stop my
application for several hours if I continue with this usage.

[google-appengine] Error Log?!

[sternr]

Hey,
I've just uploaded my first test web-app.
And while on my dev environment it works well, I get "Error: Server
Error" for all my requests.
When I look at the admin console, in the dashboard it tells me 100% of
my requests are errored, but when I try to look at the logs - I see no
error log (actually no logs at all besides "requests only").

I'm probably missing something stupid, but have no idea what it is ;)

Any help?

Thanks ahead!

[google-appengine] Cant Upload my app files to the AppEngine

[Blackbird]

Hi,

This is a wierd problem that i've been facing... I cant upload my app
to my AppEngine account using the appcfg.py script.
The issue is, when i'm running the command through the DOS command
prompt, its giving a time out exception or a host unreachable
exception.

However, i can access appengine.google.com using my web browser, and i
have no http proxy to go through...

Any ideas guys? Or is there any other way to upload the app on to the
appengine server?

Cheers,

BlackBird

[google-appengine] Data Viewer Errors

[gg]

Anyone else seeing:

Server Error

A server error has occured.

Return to Applications screen »

When trying to paginate through your data in Data Viewer

This is not a problem with corrupt data (should not matter but I guess
there is a bug that says it does) as I can replicate it on 3 different
applications and it occurs randomly. It also seems to occur 100% of
the time when you reach a certain point in your data. My guess is the
Data Viewer is suffering from the same time outs that are ubiquitous
to our Google App Engine Applications.

[google-appengine] Re: datastore .order question

[David Wilson (entertainment cloud)]

ok, i wanted to be sure about this, as pulling all the records and
just returning one would have been a performance disaster for my app.

my question was raised because i was a little surprised to read that
offset queries still pull all the 'upto' offset out of the store.

does the same apply to Thing.all().filter('value >'  x).get()  ?

and thus is it possible to page without pulling all the previous pages
data from the store each time?

i think the static files are themselves kept in the datastore.. and

[google-appengine] datastore .order question

[David Wilson (entertainment cloud)]

Hi,

class Thing(db.Model):

value = db.IntegerProperty(required=True)

datastore has 10 Things with value 1..10

Question:

How many records does the query Thing.all().order('-value').get() pull
from the datastore?

App Engine is really a much lower level platform than that. You could
probably write your own AJAX stuff like you suggest using JavaScript,
being helped out by a library like jQuery.

[google-appengine] Re: Polymorphism: one-to-many relation how to store and retrieve efficiently

[djidjadji]

And you need multiple queries to get all the Shapes that belong to the Page.
When we make a new Shape subclass we have to update the retrieval in
the Page too.

I just read about the entity-index-limit at
http://code.google.com/appengine/docs/datastore/queriesandindexes.html
When a Page has a lot of shapes (many items in the ListProperty) it could
happen that the entity is not stored because we hit this limit.

A possible solution is that we give the Shape a Reference to an implementation.
The implementation attribute points to a Line or Circle object.
---
class ShapeProxy(db.Model):
 onPage = db.ReferenceProperty(Page,collection_name="shapes",required=True)
 implementation = db.ReferenceProperty(collection_name="imp",required=True)
 def draw(self):
   return self.implementation.draw()

class Shape(db.Model):
 color  = db.StringProperty(required=True,default='black')
 def draw(self):
   return ''

# creation has to change too
---
When retrieving shapes it might be better to collect the keys of the
implementations first,
then do a dg.get(shapeKeys) and then draw the Shapes.
For this method we have 2 objects for every Shape that we use.

Is there another method to prevent this entity-index-limit?

[google-appengine] appenginepatch 0.8 released!

[Waldemar Kornewald]

Hi,
we've released a new appenginepatch version. This time we have easy to
use zip packages integration and a new sample project that comes with
a zip-packaged Django version. We've also fixed a few bugs and added a
workaround for a bug in App Engine which finally allows to use lazy
translation objects with ModelForm.

You can find all the details on the project page:
http://code.google.com/p/app-engine-patch/

[google-appengine] Re: Does the datastore cache?

[Josh Heitzman]

Just tried my app and I'm seeing changes show up immediately as
expected.  I was having some issue with page caching until I added:



to the head element of my pages.  If you can reproduce the problem
yourself, you can check your logs right after seeing the problem to
see if the request actually got to the server or if a cached version
was actually rendered.

[google-appengine] Polymorphism: one-to-many relation how to store and retrieve efficiently

[djidjadji]

Hello,

I'm looking for a way to store and retrieve a polymorphic one-to-many relation.
The test case I used is for a drawing on a page to contain different
shapes (lines,circles,...).

In my first attempt I used a ReferenceProperty in the Shape class to
the Page class. (see code section 1)
The objects (lines,circle) are stored correctly with all the
attributes, but the Page object can't retrieve
the shapes it contains probably because the shapes-Query looks something like
"SELECT * FROM Shape WHERE onPage=:1", page
and there is no Shape instance, only Line and Circle instances that
have the correct onPage attribute.

My second attempt is to use a ListProperty(db.Key) in the Page class,
like suggested for the
many-many relations. (see code section 2).
Now the creation of the shapes with a classmethod, extra put for every
shape created.
The output I get is correct. The Page draws the shapes it contains.
---
Page: Number1
Line (0,0)-(10,5) in red
Line (10,5)-(5,-10) in orange

Page: Number2
Line (0,0)-(1,5) in black
Circle (0,0)r3 in green
---

The question I have is, is this the most efficient method to store
this from a datastore point of view?
Is there a problem when the ListProperty(db.Key) has a lot of items?
What number of items is no problem for a ListProperty?
Will it have a big impact in retrieving a Page instance when it has a
lot of 'shapes'/db.Key's in the list?
