[google-appengine] Cron is 301

[筱枫]

My application needs to use 301 to my APP domain.


if not os.environ.get('HTTP_HOST').endswith(domain) and
os.environ.get('HTTPS') == 'off' and os.environ.get('X-AppEngine-
Cron') is None:


But why Cron is 301?

os.environ.get('X-AppEngine-Cron') is None :Ineffective?

Re: [google-appengine] Wouldn't it be great if pull queues supported arbitrary tagging

[Robert Kluin]

I offerred to buy Nick a shot/glass of what ever he likes to drink if
he can make this happen.  He looked pretty tempted. Maybe if a few
other people volunteer to contribute a shot/glass we can help this
along  Of course staring the issue is a good start too.

Pull queues make a lot of very neat things possible.  Having some type
of grouping will make some truly awesome things possible.

Re: [google-appengine] Re: How can I test backends with my free app

Oh, right.

To get backends to work in the development app server you need to pass
it the '--backends' option.

[google-appengine] Re: How can I test backends with my free app

[Richard Arrano]

What I think he was referring to, and a problem I've encountered, is
working with Backends in the development server. The dev server will
not acknowledge the presence of Backends - the link is listed in the
admin console, but it won't list any backends you've configured in the
yaml file. Are these meant to only work on the production server? I
actually was trying to experiment with the backends-io you linked to
and I could not get it to work on the dev server at all.

Re: [google-appengine] Drop Table equivalent?

[nischalshetty]

What is your suggestion for apps that get a huge amount of user data and 
don't really need the user data after say a week or two? Is it advisable to 
clean up by deleting them or should we just let it stay?

I';m asking this because deleting is not cheap either.  So what works out 
better for appengine users, deleting or letting the data be there in the big 
table?

[google-appengine] Wouldn't it be great if pull queues supported arbitrary tagging

[Jason Collins]

As pointed out by all-around-smart-dude Robert Kluin, it would be
great if you could place arbitrary tags on a task when submitting to a
pull queue, and then lease the tasks back out with that tag. This
would provide a great, built-in mechanism to do groupings, etc.

This would yield:

  q = taskqueue.Queue('pull0')
  q.add(taskqueue.Task(payload=payload_str, method='PULL',
tag='mytag'))

and

  q = taskqueue.Queue('pull0')
  sometasks = q.lease_tasks(3600, 100, tag='mytag')

where "tag" is an optional kwarg in both cases.

[google-appengine] App.yaml and Handlers and Instances

[Brandon Wirtz]

With the way Handler Caching works, if I have a different handler for
different functions of my app will instances cache both handlers and
"handle" both functions? Or will some instances handle one thing, and some
instances handle another?

 

I am asking because I got to thinking that through better memory management
I could speed up some of my requests if the instances were single purpose,
but I didn't want go through the trouble of optimizing code if all instances
handled all types of request.

Re: [google-appengine] Re: What do you want to see answered in Greg's pricing FAQ?

[marcdmarc]

Hello Greg,

Just wanted to add a suggestion.  I am considering upgrading to the support 
plan for $500 a month.  Something to consider may be to add additional 
"free" quota for those who are signing up for this plan, since they are 
committing to a monthly minimum.  Depending on the amount of extra "free" 
quota extended to these accounts, this may help those of us who are not sure 
weather it is worth the purchase.

I know there are many hobbyists out there, but for those who are complaining 
about going from $1.00 a month to $9 a month, that should be the least of 
your concerns.  For those who are actual startups, what we should be asking 
is questions like the following:

If my current bill was $1000/mo, how much would these new changes to App 
Engine make my new monthly bill?  Would it be $4000, $10,000, $40,000?  This 
would really help me determine if I need to seek additional funding to 
launch my startup on App Engine, or if the costs are reasonable enough, if I 
could continue to support growth out of my own pocket until a break even 
point is reached.

The more transparent details you can provide, the better decision startups 
can make to determine their capital needs.

Re: [google-appengine] Re: Possible to Defer Tasks to Backend

[Greg Darke (Google)]

Hi Aaron,

I did not realise that the deferred api does not pass the target
parameter on. For the moment, you can either modify your app.yaml file
to ensure that all tasks inserted on a queue are sent to the specified
backend or you can patch deferred.py and upload it in your
application.

As for your question about the pipeline api, if you the call to
pipeline.start occurs in a backend, then all tasks created in that
pipeline will execute on that backend.

If you would like it to support the target parameter, please file a
bug on the issue tracker for that project -
http://code.google.com/p/appengine-pipeline/issues/list.

Re: [google-appengine] New pricing causes bizarre design

[Jeff Schnitzer]

In one of the I/O 2011 sessions, a Googler building an in-house app
describes how he uses the blobstore + file api to load a large data
blob and perform in-memory searches:

http://www.google.com/events/io/2011/sessions/coding-for-the-cloud-how-we-write-enterprise-apps-for-google-on-app-engine.html

It feels to me like a huge hack to get around indexing limitations of
the datastore, and low-volume enterprisey things like this really
would be way better done with a simple SQL store.  "All I have is this
hammer..."  I'm surprised that in-house apps aren't using a beta
version of appengine's SQL store.

For your 3d lattice, the biggest question really is "how big is it".
I'm guessing it isn't very large otherwise you wouldn't consider
serializing it.  In this case, storing it in the
datastore/blobstore/memcache is a pretty good idea assuming you don't
have high-volume query demands.

If you get into the tens-to-hundreds of megabytes, you're in the area
where a Backend makes sense.  Except that backends are ludicrously
expensive and you can just as easily run an in-memory index like this
elsewhere in the cloud for one-sixth to one-tenth the price.  Beware
the hard limit of 1G and the $460/mo that a B8 will cost you.

Hi Yoav,
  You could try running the update with the --verbose flag.  I would
also suggest changing the version number.

Re: [google-appengine] Re: Lot's of requests per user, aggressive caching or what?

[Ikai Lan (Google)]

Any chance you have control over the client? If you are using caching,
chances are good many of the requests are "no ops" and you are just checking
for changes - in this case you should be polling for a version number, not
the data itself. The client checks the version number against the locally
last known version and re-requests the full data if needed.

Another alternate implementation is to generate a obfuscated URL, maybe
using UUID + SHA1 hashing. Example:

/some/url/891893984ajkskakska23

Send a redirect back after a user authenticates and proxy cache the
obfuscated URL. For some weak security, time the data out hourly so users
always need to receive the redirect to get the data.

You have a lot of different requirements that are not particularly easy to
engineer for; you either need to accept the costs or engineer workarounds.
Some of these workarounds will require requirement compromises.

Re: [google-appengine] Drop Table equivalent?

[Ikai Lan (Google)]

Just as an FYI if you are constantly deleting entities, there are
performance implications. Deleted data is soft deleted and asynchronously
deleted off disk at a later time, so it adds some non trivial cost to index
traversal times (you are still having to skip all the deleted rows on disk).
It's similar to how OPTIMIZE TABLE works in InnoDB for MySQL (
http://dev.mysql.com/doc/refman/5.1/en/optimize-table.html) - the space
isn't really reclaimed until we do a table compaction.

You may want to check out these links:
Read the following GettingStarted section.

Using the above tool, you can write a python script to put your lat, lng
values in the datastore .  Read this, and it will show you how.

Both of the sites are working for me. Since you were able to make it work
with a /etc/host change, this tells me something was probably wrong with
your DNS cache in your browser intermittently.

Re: [google-appengine] New pricing causes bizarre design

Hi Bob,
  Some thoughts inline.

How big is this object?  If it is over 1mb then you're going to need
to shard it across multiple datastore entities.  If you will know the
'addresses' of the nodes you'll be interested in, then using those
'addresses' as the key_names might be another option to consider.
Otherwise, if the object will be under 1mb, and the cost of
serializing / deserializing it is acceptable, storing it in a single
entity might not be bad.

I suggest you think about the frequency of each event (ie write vs
read) and how you need to access and present the data.  Optimize for
the common cases.

Well, it takes time to serialize / deserialize the data, during that
time that instance will be occupied.  In other words you should figure
out which option is the fastest for the 'common' operation(s), because
that will make your app as a whole perform better and be more
cost-effective.

Yeah, you might not even need to read all of the data on updates.  If
you have all of the data you'll need, and you know the key(s), you
could just overwrite any existing data.  Obviously this depends on
your use-case, but it is something to be aware of.


I'd suggest you do some simple experiments to figure out what method
will be best for your use-case.

[google-appengine] Re: Charging for memory using Megabyte.hours

[Kaan Soral]

I was just thinking about this, great idea!

0.1$'s for 1 hours is already A LOT

since it's 35mb/hour for python apps ( assuming a request consumes
35mb's of memory),
Let's compare it to a dedicated server with 12gb's ram and 200$
monthly fee: That would make 342 instances, 0.58$ monthly for every
instance, 0,020$'s daily, <0.001$ hourly

So compared to a dedicated server we currently pay x100, which is
acceptable-ish, but x200, x300 would be too high

Memory was always a bottleneck for me while managing LAMP, basically a
server's capacity is Ram/Request_Consumed_Ram requests every moment
And since Web is shaped around API's that consume a lot of time while
data is being transferred, memory being the bottleneck should be valid
for nearly everyone

Megabyte hours would be a great solution

Re: RE: [google-appengine] Re: 1.5 improvements Make me less scared of Pricing

[Dennis]

Thanks for the tips, Brandon!

A quick question: those "scratchpad" datastores are python dicts, right?   
We need to be aware that the dicts are not coordinated across instances so 
they may have stale data (which might be ok depending on the app).  Just 
want to make sure I understand your suggestion.  

Thanks,
Dennis

[google-appengine] Channel API NS_BIDING_ABORTED

[ungarida]

Hi, I'm developing a Javascript client using Channel API.
I'm testing that the channel will be live for a long time,
hypothetically days.

In the first implementation the onError handler checked the timeout
error and then tries a new channel creation. As I wrote here
http://code.google.com/p/googleappengine/issues/detail?id=4940 after
four hours the onError hanlder recieves an Unknown SID error.

I made a second implementation with a timer that every hour closes the
current socket and creates a new channel, now my problem is that with
HttpFox in Firefox I'm registering a lot of consecutives HTTP errors:

GET   http://talkgadget.google.com/talkgadget/dch/bind (Aborted)text/
plain (NS_BINDING_ABORTED)
CONTENT -> Error loading content (NS_ERROR_DOCUMENT_NOT_CACHED)
GET   http://talkgadget.google.com/talkgadget/dch/bind (Aborted)text/
plain (NS_BINDING_ABORTED)
CONTENT -> Error loading content (NS_ERROR_DOCUMENT_NOT_CACHED)
POST http://talkgadget.google.com/talkgadget/dch/bind (Aborted) text/
plain (NS_BINDING_ABORTED)
CONTENT -> Error loading content (NS_ERROR_DOCUMENT_NOT_CACHED)

are all these errors expected or I'm doing something wrong?

[google-appengine] Failing to update app - "Client Error (400) The request is invalid for an unspecified reason."

[Yoav]

Hi all,

Ever since yesterday I've been encountering the following error when
trying to update my app:
"""
...
Cloned 1400 files.
Cloned 1500 files.
Uploading 1 files and blobs.
Uploaded 1 files and blobs
Precompilation starting.
Precompilation completed.
Starting deployment.
Rolling back the update.
Error 400: --- begin server output ---

Client Error (400)
The request is invalid for an unspecified reason.
--- end server output ---
"""

This is similar to the following bug:
http://code.google.com/p/googleappengine/issues/detail?id=4820&q=Client%20error%20400&colspec=ID%20Type%20Component%20Status%20Stars%20Summary%20Language%20Priority%20Owner%20Log

However, I'm not using an error handler in app.yaml. I'm using Python
and the latest (1.5.0) SDK.
I should also note that before it started I cancelled an update in the
middle. I ran "appcfg.py rollback" since with no errors. Doesn't help
though.

Is there any way I can further debug this issue? Any logs that
indicate the actual error behind the scenes?

Thanks!
Yoav

[google-appengine] Restarting server in Eclipse won't deploy changes

[chrism]

Why is it that when I stop and restart the dev server after making and
saving .jsp changes (by clicking the 'red box' icon to terminate the
app and run > debug as > web application to restart), my changes
aren't deployed.

I have to actually close the project and reopen it (or close and re-
launch Eclipse for the changes to take effect).

Thanks in advance.

[google-appengine] New pricing causes bizarre design

[Bob]

Hello,

I've started writing GAE app that will have a 3D lattice object model with a 
couple of thousand nodes per user. Each request will typically need to read 
and analyse 1-2% of the records to walk the model in order to find the 
target node and half a dozen writes to update it and it's neighbours.

With the new pricing I'm now thinking of storing the model as a single large 
serialised object, with one read to get the whole thing and one write to put 
it back after manipulation in memory.

It *seems *wrong to be reading and writing so much **unchanged** data but 
we're being charged per datastore API operation not by actual volume.The CPU 
cost of serialising and de-serialising is, apparently, irrelevant.

I must surely be missing something?

(It does mean that if I decided to migrate away from GAE I can replace all 
the clever storage with a flat file!)

If we're charged per record on bulk fetches (still to be decided?) then this 
strategy might be good for iterating over any list. Storing a serialised 
copy of the whole collection along side the individual records would add one 
(large) read and one (large) write per record update but would allow 
iteration for one read rather than "N".

Admittedly I'm new to GAE and haven't really studied this through yet, but 
Google's policy of charging a "real" monetary value for "real" resources, 
CPU time, disk space, network bandwidth, via an "abstract" resource concept 
like datastore API calls seems like asking for trouble. Developers will 
always try to optimise their costs so Google needs to set charges based on 
what _they_ want optimised. I can't see how minimising the number of 
individual API calls can possibly be a real target for Google.

I think I'll investigate other hosting possibilities before committing a lot 
of time to learning this one. I can't guess at how much it's going to cost 
and I haven't the heart to fight.

Bob

[google-appengine] Index Building Stuck

[PWBDecker]

App ID: wedarethegame.com

Issue: Index Building Stuck

I have uploaded an index definition file which has exhausted my index
quota at 200, and the majority of them (~165) are stuck in the
BUILDING stage and have been for weeks.  I have since refactored my
code back down to using approximately 40 indexes, however I can not
upload this new index.yaml definition because it complains that I'm
out of index quota and vacuum_indexes will correctly identify the
definitions will are no longer being used and say it will delete them,
however this results in no change in my actual Datastore Index
Dashboard.  Is there something you can do on your end to kickstart
this process or mark them all in error so I can vacuum them?

Thank you,

Jared

[google-appengine] Help in uploading a file from Widows Mobile 6.5 device to GAE blobstore

[Chimbu Aravind]

Hi,

Need some help in uploading a file from Widows Mobile 6.5 device to
GAE blobstore


In the GAE server, I have the following python code; (Its still
crude.. )

class GetNewUploadUrlHandler(webapp.RequestHandler):
def get(self):
upload_url = blobstore.create_upload_url('/upload')
self.response.headers['Content-Type'] = "text/plain"
self.response.out.write("%s" % upload_url)
logging.info("\n\n from hgetuploadurl - %s",upload_url)


class UploadHandler(blobstore_handlers.BlobstoreUploadHandler):
def post(self):
upload_files = self.get_uploads('file')
for ufile in upload_files:
blob_info = ufile
logging.info("key = %s",blob_info.key())
#
blob_reader = blobstore.BlobReader(upload_files[0].key())
# Further processing of the file


In the device we have some C# code to test the implementation, which
uploads a jpg file

private void button1_Click(object sender, EventArgs e)
{
String WebUrl = "http://xxxserver.appspot.com/
getnewuploadurl";  //xxx is a dummy name not the real one

HttpWebRequest httpRequest =
(HttpWebRequest)HttpWebRequest.Create(WebUrl);
httpRequest.Timeout = 15000;
httpRequest.ReadWriteTimeout = 2;

using (HttpWebResponse httpResponse =
(HttpWebResponse)httpRequest.GetResponse())
{
Encoding enc = System.Text.Encoding.GetEncoding(1252);
StreamReader loResponseStream = new
StreamReader(httpResponse.GetResponseStream(), enc);
string Response = loResponseStream.ReadToEnd();

MessageBox.Show(Response, this.Text,
MessageBoxButtons.OK,
   MessageBoxIcon.Hand,
MessageBoxDefaultButton.Button1);
{
HttpWebRequest req =
(HttpWebRequest)WebRequest.Create(Response);
req.Credentials =
CredentialCache.DefaultCredentials;
string boundary = "frontier";
req.Method = "POST";

req.ContentType = string.Format("multipart/form-
data; boundary={0}", boundary);

req.AllowWriteStreamBuffering = true;

// Retrieve request stream
Stream reqStream = req.GetRequestStream();

string imageType = "image/jpeg";
string fileName = "test.jpg";
string header = string.Format("--{0}", boundary);
string footer = string.Format("--{0}--",
boundary);
string NewLine = "\r\n";

String payload1 = string.Format("{0}{1}Content-
Disposition: file; name=\"file\"; filename=\"{2}\"{1}", header,
NewLine, fileName);
String payload2=string.Format("Content-Type: {0}{1}
{1}", imageType, NewLine);

String payload = string.Concat(payload1,
payload2);

byte[] HeadData =
Encoding.GetEncoding("utf-8").GetBytes(payload.ToString());

reqStream.Write(HeadData, 0, HeadData.Length);

// Open the local file
String path =
System.IO.Path.GetDirectoryName(this.GetType().Assembly.GetModules()
[0].FullyQualifiedName) + "\\test.jpg";
FileStream rdr = new FileStream(path,
FileMode.Open);

// Allocate byte buffer to hold file contents
byte[] inData = new byte[4096];

// loop through the local file reading each data
block
//  and writing to the request stream buffer
int bytesRead = rdr.Read(inData, 0,
inData.Length);
while (bytesRead > 0)
{
reqStream.Write(inData, 0, bytesRead);
bytesRead = rdr.Read(inData, 0,
inData.Length);
}

byte[] FootData =
Encoding.GetEncoding("utf-8").GetBytes(footer.ToString());
reqStream.Write(FootData, 0, FootData.Length);

rdr.Close();
reqStream.Close();

req.GetResponse();

};
};
}


Problem:
When I tested the server and the C# client in the device using the GAE
development server; it worked fine.
However after I uploaded the server to the Appspot.com,
req.GetResponse(); fails with error code 503 (Service not available)

Only difference I see between running GAE development server and the
Server in appspot.com is the size and structure of the upload url
generated by the GAE blobstore

eg: with appspot.com url generated is
http://xxxserver.appspot.com/_ah/upload/AMmfu6aEjWpmkRhysTsf8LeZPGjOUB_G2GScVr43zcsShpwHwSiglMCLVyXlr2kl0pDmb4wKwJwub1hk9pTRhenib0fs98IMILBGo_bTdh4gN8DjgHhIwOk/ALBNUaYATdDYcj3Cgn0TJoqquBKVL9Y2jDmL0Jyg/

Where as with the development server, it is much smaller.

[google-appengine] Consolidated payment

[PR]

Hello App engine users,
  I would like to ask googlers, if it is possible to proceed payments
in consolidated way somehow. We have more apps, which costs us about
2USD per week. For 2 apps, that means 8 invoices per month for total
16USD. Our finnancial dpt. is angry about that. Thank you for answer
and great service!

Re: [google-appengine] Caching GeoModel requests?

[Rodrigo Souza]

You should compute the GeoBox for your location, and then query/cache the
geobox.
Take a look inside the geomodel source code for geoboxes.
You might have to modify the geomodel source code.

Thanks,

[google-appengine] Index Building Stuck

[PWBDecker]

Hi,


I suffered from an 'exploding index' problem, filled my 200 index
quota, and then refactored my code back down to about 40 indexes.
However, when I first tried pushing my exploded index definition up,
it added 160 indexes that registered as 'building'.  I've since
changed my index.yaml to show only the indexes that are being used,
but the 160 superfluous indexes still show as building, and
update_indexes fails because I've exceeded my index quota,
vacuum_indexes lists the unused indexes and says it will delete them,
and I can not push a new code version because I've exceeded my quota
index.  What can I do here?

Thank you,

Jared

[google-appengine] How can I test backends with my free app

[Sergey]

I want to test new feature - backends.
As I understand it's enough to create backends.yaml and describe there
parameters of my backends.
I've done that:

backends:
- name: testbe
  class: B1
  instances: 1

I ran this app on dev server. At admin console I see "This application
doesn't define any backends. See the documentation for more."

I tried to deploy this into GAE - same effect.

What am I doing wrong?
Is there some code examples to better understand the idea of backends?

[google-appengine] Re: What do you want to see answered in Greg's pricing FAQ?

[J Jones]

FAQ Question suggestions:

- Does the Instance Hour pricing as opposed to now means GAE is now
unaffordable for part time hackers e.g. college students, those
working on self funded projects in their spare time?  What is Google's
position on this?

- Did GAE provide sufficient information that such a fundamental shift
in the way apps are charged was a possibility, when folk signed up to
GAE . Such detail may have influenced many folks switch to GAE in the
first place.

[google-appengine] Re: Is App Engine suddenly becoming more expensive???

[carlosten]

So, now we are paying for instances, but, Can we share for example one
instance with 5 or 6 applications with low traffic? Or have one to pay
5 instances for have online 5 applications?

If the second, I waste my time in learning appengine...

[google-appengine] Re: Getting one bill a month for the App Engine Usage

[vinhboy]

I get charged $.02 a month for appengine use. Can google please
implement a "minimum" charge for appengine.
Although I like the idea of bankrupting google via processing fees, I
kind of need gmail so I don't really want that to happen.

[google-appengine] Re: What do you want to see answered in Greg's pricing FAQ?

[Rafael Nunes]

7) API quota are daily?
8) What is a XMPP instanza? One client connected? One message sent/
received? We will have 1000 instanzas daily?
9)Reserved Frontend instances are something like Always On, they will
be always running?
11) Email API will be 100 recipients emailed? Received? Both?
12) How much RAM my instance will have?

[google-appengine] Memcache proper use?

[blue]

I've been designing my app under the impression that memcache was relatively 
large, however, I keep reading the contrary.  My app needs about 1gig worth 
of memcache space in order to be cost effective, otherwise my hits to the 
datastore will kill my budget.  When a user is logged into my app, they need 
to read and write their user object on every request and if I have 10 
simultaneous users then I will need about 1gb of memcache  to store all 
entities.

If memcache is only 10mb or 100mb then memcache will be completely useless 
for this scenario, I will never get a cache hit because I will be simply 
cycling new data though memcache.

Is this how memcache works?  Should I not be caching user data in memcache?

Re: [google-appengine] DeadlineExceededException - how to avoid?

[Francois Masurel]

Does this still work with SDK 1.5.0 ? It doesn't seem to be the case.

And why are instances restarted causing "Server Error" responses after these 
exceptions ?

Thanx for your help.

[google-appengine] Re: TypeError in urlfetch_stub.py for SDK 1.4.3?

[IgorNovak]

Hi. Recently I've faced with the same problem. It appeared in v1.4.3
firstly but since it didn't bother me a lot I did nothing hoping it
would be fixed in v1.5.0. However it still isn't.

The error appears in this place:

urlfetch_stub.py (Version 1.5.0)
293 if payload is not None:
294   escaped_payload = payload.encode('string_escape')
295 else:
296   escaped_payload = payload
297 logging.debug('Making HTTP request: host = %s, '
298   'url = %s, payload = %s, headers = %s',
299   host, url, escaped_payload, adjusted_headers)

In my case the type of payload variable is unicode, that's why the
TypeError appears. There was no problem before v1.4.3 because the
encode method wasn't used:

urlfetch_stub.py (Version 1.4.2)
228 logging.debug('Making HTTP request: host = %s, '
229   'url = %s, payload = %s, headers = %s',
230   host, url, payload, adjusted_headers)

As you can see this code doesn't play an important role, so I can just
comment out it and everything will work fine. However I'm afraid this
can cause more serious problems in future.

So the question: is it a bug or new behavior? In first case I can just
wait for fixing it. In second case I have to change my code in order
to avoid this problem.

[google-appengine] Re: What do you want to see answered in Greg's pricing FAQ?

[Sylvain]

Hi,

With the actual prices, a very small paid app that only need 1GB above
the free quota costs : $0.15 / month.
With the new prices : $9 (monthly fee) + $0.15 = $9.15.

Old price $2 / year -> new price $110/year  (+ $108)
So it increases the price by x55.

For these app, the increase is very high.
What will you answer for them ?

Regards.

RE: [google-appengine] older version data showing in default version

[Brandon Wirtz]

Are they Static?   Did you set the App.yaml  to have too long an expire?

 

Are you on HR or MS?

 

If you put ?1234 at the end of the file do you get the wrong one?

 

 

The Mark up of your page should have the version number of the file in the
CSS.. Either as CacheBuster   my.css?v1234 or as the file name my-v1234.css
This is just a general best practice for programming.

Hello,

 

We are facing some abnormal behavior at appengine,

 

We have one default version, which is showing data from different version at
each refresh. We made lot of work considering it as a bug in our code but
could not find any flaw. 


I am not able to explain wt the error is to either the client or the
management. 

 

Any one having any idea about this please respond to this post. 

We cant handle this with appengine if the live mode is some kinds of errors
like this...

 

also some times there is abnormal usage of quotas even if there is no
traffic to the site..

RE: [google-appengine] older version data showing in default version

[Brandon Wirtz]

All versions share a data store, if you versioned your data store you need
to assign a new kind.
