Re: [google-appengine] Large latency spike, need assistance

[Takashi Matsuo]

Hi Nathan,

I think it's OK now. Are you still seeing this?

BTW, this list is not a support channel with any kind of SLA. Now
we're offering premier support for that type of demand.
For more details about our premier support, please see:
https://developers.google.com/appengine/docs/premier/

Regards,

Could anyone point out the docs?

[google-appengine] Re: NDB Caching Question

[Richard Arrano]

Do you mean rather than pull my 2500 entities, use a task to keep the
2500 updated in a single JSON property and then use it to sort on a
desired property as necessary? I was considering doing this as an
alternative. It seemed wasteful in my usage scenario to pull 2500
entities just to give the user back 50 or so, but to do it with
indexes caused a huge explosion in storage costs. Did you guys do any
experiments to see what was faster in your case?

Thanks,
Richard

[google-appengine] Re: App Engine 1.6.5 Released

[Warwick Allison]

Projection queries do not seem to work for properties that are
db.ReferenceProperty(). So for example, this works:

   SELECT * FROM Person

   result.mother.name + " is the mother of " + result.name

but this does not:

   SELECT name,mother,father FROM Person

Is this just an oversight, or an undocumented permanent limitation?
(if the former, I'll wait, if the latter I may redesign my db to not
use ReferenceProperty just to see what the performance improvement is
like!).

(no, I don't actually have a Person database, this is an example ;-)

Meaningless error message when I try to upload a file using the

I have billing enabled and it works locally. Any idea what might cause

RE: [google-appengine] Re: What am I being build for?

Because Google is losing money on you already. I don't have insight in to
the exact numbers, but much like banks with Checking and Savings Accounts.
Banks lose money on accounts with less than $20k a year in transactions.

 

Google loses money on accounts with less than $X a year in usage. I'm
guessing that number is something like $800 a year.

 

The Free quota is a marketing loss leader, and away for you to do test
development.  If you can't afford $2.10 a week you are doing your app wrong.

 

Works out that on my primary sites my Appengine Costs are $0.032 CPM Even if
you totally suck at monetization you should be able to make this back.
($6.70 eCPM is the current English Site Average CPM according to Ad Age)

[google-appengine] Enable Billing - only if over free limit

[Erin Hastings]

So I built my app a couple months ago and still waiting to deploy it. The 
whole time its been billing me a minimum monthly fee, despite using 
virtually no resources, and I didn't even know it.  

It is not clear at all that if set up billing you will be charged a minimum 
monthly fee no matter what usage. The way it should work is that you only 
get charged if you go over the limit. Why doesn't it work that way?

[google-appengine] Re: Error with Xerces on Appengine

[Kyle Anderson]

I figured this out--
 You should not include xerces.jar and xercesImpl.jar when you
deploy.  It is necessary to run locally, but I guess it already
resides on the app engine server, so it causes problems.

[google-appengine] Re: NDB Caching Question

[Alexander Trakhimenok]

Richard, I would advise to go with the JSON property. In our project
we intensively use JSONs and update them in task queues & backends.
Actually we have a rule - every page should make just 3-5 DB requests.
In future we would consider to move from JSON to ProtoBuf but not for
now.

Also we've moved some rarely changed dictionaries (like geo locations
- e.g. all cities in the world) into the Python code. That pushed us
to use F2 instances due to higher memory demand but resulted in lower
latency and almost same costs. It's cheaper to upload new version of
app when needed.

If they pull from memory they don't show up in Appstats at all. Otherwise 
they'll probably look like a memcache Get possibly followed by a datastore 
Get.

If you're considering storing a pickled entity, you should look into 
LocalStructuredProperty, which is a little bit more efficient (but doesn't 
store the key).

There are too many unknown variables here. You're best off benchmarking

[google-appengine] Error with Xerces on Appengine

[Kyle Anderson]

I receive a strange error relating to xerces on the app engine.

My application runs fine in my local development environment.

I've tried everything:
1.) I have  el-ri-1.0.jar in my WEB-INF/lib
2.) I have xerces.jar and xercesImpl.jar in my WEB-INF/lib
3.) I tried to use Saxon instead of xerces, and received a similar
error.

Re: [google-appengine] Re: Mail is not sent to domain with google apps

[Deepak Singh]

Hi Barry,

Thanks for your reply.

I checked it once again and i found that sometimes mail is delivered to
spam and sometimes it goes to inbox.

The content of the mail is only professional content and without
attachments. It is text/html plain.

Can you give some hint why it goes to spam more often?

Thanks
Deepak

[google-appengine] files.blobstore.create ApiTemporaryUnavailableError

[Brian G]

For the last several days, AppEngine has been throwing
ApiTemporaryUnavailableError whenever files.blobstore.create() is
called. I am passing no parameters to the create call.

I realize this is an experimental feature; has it been removed from
AppEngine? Is there an alternate method for creating blobs on the fly?

I have a desktop application that uses Microsoft BITS to transfer data
from AppEngine. The only way I could get data of any size to download
using HTTP RANGES (required for BITS) was to serve the data using
blobstore_handlers.BlobstoreDownloadHandler.

The data is retrieved from the datastore, formatted into XML, and
saved in a blob using files.blobstore.create(). The blob is saved and
used for all subsequent requests for matching data.

App name: mcneel_app_store, version 2.

Thanks in advance for your help, my app is dead without this feature
working, and shortly my customers will notice and start screaming.

[google-appengine] Large latency spike, need assistance

[Nathan Skone]

Application: hs-hbo
Datastore: High Replication
Normal latencies: 50ms-200ms
Today's latencies: 5000ms-1ms
Idle Instances: ( Automatic – Automatic )
Pending Latency: ( Automatic – Automatic )

Dear Appengine Team,

This morning the latency of my application saw a sudden spike that has made 
it unusable for my company's purposes. How can I get assistance with this 
problem? This is an urgent issue that is directly effecting our customers.

Thank you,

Projection queries return the properties you projected and key for each
entity that matches the query.

[pdknsk]

When using projection queries for just a single property, does this
also return keys? The answer is probably yes, as returned items can
probably not be key-less, or can they?

[google-appengine] Re: [objectify-appengine] Re: DeferredTask always gives NotSerialisable exception

[Deepak Singh]

Hi Jeff,

Here is the complete code:

here is my static inner class,

public static class CancelTriptaskOperation implements DeferredTask,
Serializable {

private PackageEnqFormDTO enq = null;
Objectify objectifyDeferred = ObjectifyService.begin();

public CancelTriptaskOperation(final PackageEnqFormDTO enq1) {
this.enq = enq1;
}

@Override
public void run() {
try{
enq.setStatus(YFConstant.CANCELLED_ENQUIRY);
LinkedHashMap convMap =
enq.getLeadAndConvMap();
Set keys = convMap.keySet();
Iterator itr = keys.iterator();
while(itr.hasNext()) {
String key = itr.next();
PackageConversationDTO convDto = convMap.get(key);
convDto.setStatus(YFConstant.CANCELLED_TRIP_PACKAGE_CONVERSATION);
convMap.put(key, convDto);
}
objectifyDeferred.put(enq);
 List list =
objectifyDeferred.query(HolidayInvoiceDTO.class).filter("tripId",
enq.getId()).list();
for(HolidayInvoiceDTO holiday : list) {
holiday.setStatus(YFConstant.INVOICE_GENERATED_THEN_TRIP_CANCELLED);
objectifyDeferred.put(holiday);
}
}catch (Exception e) {
System.out.println("CommonRpcServiceImpl.TaskOp.run() "+e.getMessage());
}
}

}


Here is my method in outer class:

@Override
public boolean cancelTripEnquiry(final PackageEnqFormDTO enq) {
 try{
 TaskOptions taskOpt = TaskOptions.Builder.withPayload(new
CancelTriptaskOperation(enq));
 Queue defQueue = QueueFactory.getDefaultQueue();
 defQueue.add(taskOpt);
 }catch (Exception e) {
 System.out.println("CommonRpcServiceImpl.cancelTripEnquiry()
"+e.getMessage());
 }
return true;
}



Hope the code is understandable.


Thanks
Deepak

[google-appengine] Using conversion API to convert from text into PDF

[Computer_Engineer]

Hi, i'm working on a task that i want to convert text file into PDF one 
using conversion API that is in GAE , i tried as:
https://developers.google.com/appengine/docs/python/conversion/overview

This is the approach that i used:

from __future__ import with_statement
from google.appengine.api import files
import cgi, cgitb ; cgitb.enable()
import StringIO
from google.appengine.ext import webapp
from google.appengine.ext.webapp.util import run_wsgi_app
import mimetypes
from google.appengine.ext import blobstore
from mimetypes import guess_type
from google.appengine.api import conversion




def mime_type(filename):
return guess_type(filename)[0]
class get(webapp.RequestHandler):
def post(self):

form = cgi.FieldStorage() 
file_upload = form['file']  
name=file_upload.filename  
 
m=mimetypes.guess_type(name)[0]

data=file_upload.file.read()
buf = StringIO.StringIO()
asset = conversion.Asset("text/plain", data, file_upload.filename)
conversion_obj = conversion.ConversionRequest(asset, 
"application/pdf")
result = conversion.convert(conversion_obj)
if result.assets:
 buf.write(asset._data)

else:
 print "ERROR" 
   

u_file = 
files.blobstore.create(mime_type="application/pdf",_blobinfo_uploaded_filename="test.pdf")
data=buf.getvalue()
with files.open(u_file, 'a') as f:
  f.write(data)
files.finalize(u_file)
blob_key = files.blobstore.get_blob_key(u_file)
  
   

  
def main():
application = webapp.WSGIApplication( [(r'/get.py', get)], debug=True)
run_wsgi_app(application)

if __name__ == "__main__":
main()

But when i try to open this PDF,i can't open it and the adobe reader gives 
error immediately that it can't open the file.
Sorry i'm still beginner in these issues,any help please?
Any suggestions are welcome.

[google-appengine] Files API and Google Cloud storage

[Arne]

I am building a system that  needs to save files from Google App Engine's 
blobstore to Google Cloud Storage. It works fine for small files (<40 mb) 
but for larger files it get gets unstable and GAE throws and 
FileNotOpenedError. To my understanding the reason for this is as described 
in  GAE Issue 
5371
 that the Files API closes the file every 30 seconds. To my knowledge there 
are no way to work around this because it is not possible to re-open av 
file for writing in Google Cloud Storage. 

When I first become aware of this issue 6 month ago and asked about it on 
Stackoverflow
 and 
 the unstability started at around 10 mb. It have improved since that but 
since this all is undocumented I do not know if that is just due to the 
servers being in better mood this month. I order for me to build 
something reliable I need to know more about what this API is built to 
handle. Do anybody have some insight to share?

best
Arne

You will probably have more luck, if you are more specific.

How does it fail? "not able" is not very specific?

Do you get an error? Are you getting a stack trace?

Do the emails bounce? What does the bounce say?

What email are they coming 'from'?

Have you checked Spam folders, and filters on the destiniation email address?

Do the messages just disappear?

Can you send mail to that domain from other locations (non appengine?)

How are you sending messages? which api, and which runtime?

Are you using SPF and/or DKIM your domain?

Are they plaintext, HTML messages, with attachments?



At the moment its like you dumped your car outside a garage, and said
"my car is broken, please fix it" and not giving them any more
details.

To be able to help you the machanic needs to know specifically what
the issue is before they can even attempt to look at the issue.
(otherwise they can only guess, and will probably get it wrong - so
they wont waste their time)

[google-appengine] Re: Twitter Task Queue vs Cron

[Strom]

Easy question but a bit tricky to answer.

What's wrong with your current solution? Nothing? Then there's nothing
to fix.
If there's something wrong, then you look at alternative methods and
think to yourself "does this solve my problem?".

Does this release include a fix for this issue:

I still have problems described there if I do large asynchronous puts.

Re: [google-appengine] SMALLEST and FASTEST Template Engine on Python

[Takashi Matsuo]

Hi Ayan,

I have not tried it myself yet, but how about tenjin?
http://www.kuwata-lab.com/tenjin/

Besides that, if you can use python2.7 runtime, jinja2 is now bundled
in the SDK, and should be fast thanks to its bytecode cache, which is
only available with python2.7 runtime.

However, in most cases, the difference here might be negligible
compared to the cost of various RPCs.

I also experience the same problem in my website. 
When this thing happen I observe there is large number of request in the 
log in small time. So if your app is initiated at burst then this may 
happen. You can check logs in appengine logs and you can find requests at 
brust when this problem happens.

Yes, our apologies-- the 9am PDT one had to be cancelled (you'll see a

one is still on.
In future weeks we do plan to have hangouts in that 9am time slot.
