[google-appengine] Re: 502 server error appears google appengine? Why
i came across the same problem with my app.try correcting your app.yaml file.and name it correctly.also main file'/' should be named correctly.the main reason is your app.yaml might be broken.

[google-appengine] Re: New Limits for Several App Engine Operations
It would indeed be great to have some kind of way to store big binary blobs such as images etc. that are larger than 1mb without having to resort to using a third party storage solution like Amazon's S3. I'm under the impression though that Google is working on this (see roadmap).

You would probably be better off using a library that provides the dictionary through some form of static files that you can import as part of your app. Given the current deployment limits (10MB per file, 150MB total) that route is feasible. As for specific library suggestions, I don't think I can add much. >From a quick google search the libs that appear relevant seem to have dependencies on C libraries/Unix external programs (http:// www.johndcook.com/blog/2008/11/29/spell-checking-from-python/ ) diomedes On Feb 16, 9:20 pm, app engine dude wrote: > thanx for the reply.Is there any library or so so that i can add it to > the python library in app engine.

To me, keeping 1MB datastore entity limit while allowing 10MB request/response doesn't make much sense. It is more useful to make the limits in sync/compatible.

Looking at your log it seems that browser is requesting the /init when
it processes the html ,
I would look inside the html template for a misplaced href="/init"
inside an image tag or sth similar.

[google-appengine] Re: CPU accounting for Datastore writes and pricing feedback
Ok, (a bit bummed that nobody bother to reply to my first post to the group) I spent the last few days reading related posts, transcripts of chats with Marzia, went through the related tickets and still I have no answer. Let me try once more to explain my question: It is not about quotas. It is neither about performance per se. My question is about cost. My app implements a beacon service - my client websites that will be using the beacon have 5-10M pageviews per month and these pageviews will result into actual beacon hits to my app. These requests do not hit the Datastore - I buffer them in memcached doing minimal processing to keep the per beacon-hit cost low and "process them" in batches every few seconds. Still, in spite of all the buffering, if the cheapest write (1 attr table, no indexes) gets charged 250-500msec, this make the app design for such a high throughput service non-obvious. I understand that I can decrease the number of my writes by using a pickled blob attr that contains lots of records inside - that what I am about to do. I just wanted a confirmation from any gurus out there, or from the google team that my understanding about the cost of the "cheapest write" is correct. I tried batch db.put( of 100 single cell objects) - still took 23 seconds of data store CPU , i.e. my cheapest write = 230msec - a bit less than before but not by much. I made all 100 objects children of same parent and performed the same test - again same datastore CPU utilization Is there another method to update/insert multiple records that costs less? I.e. is there any cheaper write? ( I am very flexible :-) ) Is my understanding that the planned 10-12cents per CPU hr will be applied towards the datastore CPU usage as well?

You have to trade off flexibility (GAE doesn't let you run an RDBMS, or cron jobs, and there are several other limitations) for scalability/ redundancy. For me, not having to worry about what happens if my app hits the big time, or the particular server it is on catches fire, or if I set up the iptables firewall slightly wrong easily outweighs the extra development I need to do to fit GAE's API.

six entries.
I find this happening with soem of my other scripts also.
I didnot go my app online due to this error.

[google-appengine] Intercepting Model Creation
Short version: I want to execute code during creation of a Model subclass but I need to know whether or not the object is saved in the datastore and/or execute datastore queries. Since Model.is_saved() never returns True inside __init__(), overriding this method doesn't work. I also tried intercepting construction with a metaclass, and numerous other approaches, but nothing I've tried works. From examining the source code it appears that the Model objects aren't fully constructed until after get() returns, but there doesn't seem to be a convenient, documented location to put my intercept code. My specific situation is that I want to replace a ReferenceProperty with a value I have stored in a cache to avoid a trip to the datastore. Here's an example: class A(db.Model): str = db.StringProperty() class B(db.Model): a = db.ReferenceProperty(A) I want the following code to succeed (assuming B is stored in datastore): a = from_cache(a_key) b = B.get(key) assert a == b.a I can populate B.a with the proper value using something like the following in B: def Load(self): a_key = B.a.get_value_for_datastore(self) self.a = from_cache(a_key) But I can't figure out where to put the call to Load(). Long version: The reason I'm trying to do this is for performance. I have some very long-lived objects that use ReferenceProperty to manage relationships between them, plus a large number of frequently-created objects that use ReferenceProperty to refer to the long-lived objects. After many DeadlineExceededErrors I started using memcache to store the long- lived objects. That helped but not enough. Profiling showed that most of my time was now being spent in memcache, apparently because memcache goes to the network on every get() call. So I introduced an in-memory cache in front of memcache and now first search in-memory, then in memcache, then go to the datastore. That helped a lot and I'm now avoiding the DeadlineExceededErrors but many of my pages still take many seconds to load. Further profiling pointed out that the ReferenceProperty attributes (primarily in my frequently-created objects that refer to my long-lived objects) are hitting the datastore and causing most of my performance problems. That's the problem I'm trying to solve -- I want to be able to load all those objects and have them use the cached long-lived objects instead of going to the datastore to get them. I thought this would be a common problem but I haven't been able to find anyone else addressing this.

[google-appengine] Google Geocoding not working
Hey guys,
i'm trying to use Google Geocoding service
http://code.google.com/apis/maps/documentation/geocoding/index.html
via http.
I generated API key for actual domain and it's not working {u'Status':
{u'code': 610, u'request': u'geocode'}, u'name': u'Brno'}.
610 mean it's not good key for this domain. I tryied it on another
hosting with php, it's working. I tryied it on another hosting with
same python lib and it's working too. I tryied to use urlfetch and
urllib2, nothing works.
Any idea?
Maybe it's because of header restrictions, but i really don't know.
That link, which is called is ok, coz if i'll try it in browser,
everything works. All data are encoded before posting, there is 100%
not problem.
Thnx for help

I'm not aware of any simple and general solution, but your options include: 1) Testing on the development server (SDK) only. Check out the --datastore_path command line option. I think you should be able to create a copy of a dev datastore by copying the --datastore_path file (when no dev server is using it), but I haven't tried it. 2) Using a separate app. Each app has its own datastore, inaccessible to other apps, so you'll have to migrate your data manually between this staging app and your stable app. 3) Emulating versioned datastore manually. You will still have a single shared datastore, but you can write your code so that it never touches other versions' data. Or it can only access some other version's data under very specific circumstances. Or whatever. How this is best done heavily depends on what kind of changes you are trying to introduce to the datastore. Changes to your datastore schema can be risky. It is always good to have a full backup and test the restoration procedure periodically. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] Re: storing key value pair in datastore
You can do 2) ListProperty to a custom class. Each class instance is an object in the datastore and the ListProperty has db.Key as elements. If you have URL-description pairs you probably will not select the object based on the content of the URLs. In that case you can construct a list of tuples. Each tuple is the URL-desc pair. You store this list in a BlobProperty by using the pickle module. When you retrieve the object you unpickle the Blob and put the list in the template-var dictionary. Or use the simple json module that is part of django. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

Anyone got a better idea? First off, does your order really need to be in a transaction with order lines? If you can't avoid that portion, then you may want to consider a slightly more complex protocol for stock updates. Consider a new entity type, a StockReservation. When you create an orderline, before actually creating it, decide on a key for it. Use a random number or UUID or something to ensure it won't collide. Now, in a transaction: * Reduce the available stock. * Create a StockReservation, with parent = the Stock entity, an arbitrary key, containing the amount you reduced the stock by, a copy of the orderline's key, and the current time stamp. Then in a seperate transaction: * Create your orderline with parent = the Order entity * Update your Order entity Then in a final transaction: * Delete the StockReservation If the orderline update fails before the actual orderline creation, you could have some stale reservations; so periodically go through any StockReservations older than a minute or so, and reverse them - that is: * (not in a transaction) Select a StockReservation * Check if its OrderLine exists. If so, delete the StockReservation and stop. * Enter a transaction and: * Verify the StockReservation still exists * Add its quantity back to the Stock entity * Delete the Stock Reservation There's one more failure mode that must be addressed; if the StockReservation is not deleted, and later the OrderLine is deleted, you could end up with too much stock. This can be addressed by making sure that anything that deletes an orderline first searches for a StockReservation associated with that OrderLine, and deletes it if found. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.

It is the same single datastore out there that every version of your app can access. So if there is a difference in how two versions of your app behave, it must come from the way they work with the datastore.

Hi, Probably this question has already been asked before. What is the difference between GAE and other regular web hosting service?

The same problem occurs in me.

[google-appengine] Datastore query on both userproperty and datetimeproperty at the same time
I ran into this problem, and it's unclear to my why it doesn't work. I
looked carefully in the documentation and can't see that it should be
an illegal operation, but still, I seem to recieve no results from the
query.
What I'm trying to do is to fetch all the rows in a datastore model
that has a specific userproperty-value AND something newer than a
certain date on a datetimeproperty.
Currently, it looks like this:
class UserTrack(db.Model):
user = db.UserProperty() # Google user
parentpost = db.ReferenceProperty(reference_class=Post,
collection_name='usertrack_parentpost_tasks')
lastvisit = db.DateTimeProperty(auto_now=True)
(...)
user = users.get_current_user()
datetime_of_current_visit = datetime.utcnow()
usertrackquery = UserTrack.all()
usertrackquery.filter('user =', user)
usertrackquery.filter('lastvisit >', datetime_of_current_visit)
usertracks = usertrackquery.fetch(limit=25)
If I delete either of the two filters (on user OR on lastvisit) I get
results, but if I take the two together the datastore always returns
None (without an error). I know for sure that some of the rows are
true for both of the two conditions, but still I get None. (actually,
if none of the rows would match I would still get an empty list, and
not None).
Did I break the policy of equality filters and is that why it doesn't
work? If so how? Any ideas?

I still had to apply the changes made in r72 and r73 in __init__.py to my version of the helper to stop it from trying to access app.yaml.

[google-appengine] Re: self.request.get("userHtmlInput", None) problems
Alexander,
Thank you a bunch for your reply (again).
My problem is slightly different, and I think I have solved it as
follows. The problem is the difference between these two conditions. I
need to use them both, but separately as my code below shows.
if prevplace_id is None and nextplace_id is None:
if prevplace_id == '' and nextplace_id == '':
And btw, I finally took the step of adding a dummy application on my
development system which I named "test" that can use be used to test
this sort of question that has both python and html, because I could
not think of a way to make the gae interactive console handle such
situations.

Request.get() returns `default_value` only if the parameter does not
exist in the request. In your case, if the user doesn't enter
anything, both parameters exist and have an empty string as their
value.
Try this code:
def get(self):
nextplace_id = self.request.get('nextplace')
prevplace_id = self.request.get('prevplace')
if prevplace_id or nextplace_id:
print "we are ready to go now"
else:
print "you must supply either a Next or Prev place"
