[google-appengine] Index problem with GAE for Java

[Rmac]

Hi,

I am struggling with getting a query to work that has a simple
equality condition on one property in the where clause and one sort by
on another property.  GAE responds with a "no matching index found"
error along with the index entries to put in the datastore-indexes.xml
file.  I put those supplied entries in the file, redeploy, and then
later also look at the GAE administration console to see those indexes
are actually in "serving" status.  But, rerunning the query results in
the same error.  Does anyone have an idea how to get indexes to work
in Java GAE?

Thanks in advance.

[google-appengine] Re: Video streaming working with tag, not with flash player ?

[John McLaughlin]

AFAIK "player.swf" just takes a file link.  It doesn't ask for byte
ranges.  This on the edge of my knowledge of Flash though, I haven't
done any work with live video streaming, and I'm working from the
Python API.

I just double checked and IE8 indeed falls through to the Flash player
for my examples.  If you send me your email address I can give you a
link to a simple example page.

Re: [google-appengine] Re: Fan-in with materialized views: A sketch

[Robert Kluin]

Hey Dmitry,
   I am working on getting some decent documentation about when you
might want to use fanout versus directly using creatwork.  And, about
usage in general.  If I am dealing with one or two aggregations I
usually use creatework directly.  You can only insert five
transactional tasks in one database transaction, so with four you
could directly use creatework eliminating a fanout task.

  As far as rates go, I have been using a rate of 35/s and bucket size
of 40.  However, I also get periodic queue backups.  I think the max
rate / sec is currently 50, but I thought there was an announcement it
was getting increased (maybe I am just remembering the increase to
50/sec announcement though).  You might want to bump your rate up to
50/sec.  I always use a dedicated queue for creatework and aggregation
tasks.  In one of my apps I use multiple queues to get a bit higher
throughput.

  I generally prefer to use creatework tasks; they cleanly handle any
failures that occur and keeps my primary processing running as fast as
possible.  However, when I first started using this type of
aggregation technique I created the 'work' models and attempted to
insert the aggregator task (non-transactionaly!) within my primary
transaction.  If your primary processing is within tasks, and your
tasks are fast enough, give it a shot.  Converting CreateWorkHandler
to something you can use directly should not be a big deal.

[google-appengine] Re: Fan-in with materialized views: A sketch

[Dmitry]

Hi Robert,

What queue configuration do you use for your system?
I came to another problem. I usually process several feeds in parallel
and can insert up to 20-30 new items to the database. With 4
aggregators it's >80 create_work tasks in one moment. So after a
minute I can have up to 1000 tasks in queue... so I have up to 5
minutes delay in processing.

It seems that for initial aggregation I should insert create work
models not in tasks.
I messed up again:)

Another another set of 196 DeadlineExceededErrors.

AppID: steprep
Log time: 2010-11-08 1.40p - 1.42p
Instances: ~150

Might be worth noting that all of these timeouts were handling
taskqueue items (though that is by far the majority of our requests).

[google-appengine] Re: The request to API call mail.Send() was too large.

[GK]

Yes. I tried to send the email to ~40 recipients. Also, I just noticed
that each time I click the "send emails" button, 1 or 2 emails get
sent out, then the exception gets thrown. The attachments are large
jpg images (like 2550x3000 or something) so each individual image size
is something like 700kb.

The stack trace for the exception is:
javax.servlet.ServletContext log: Exception while dispatching incoming

Re: [google-appengine] Lots of 500ers

[Robert Kluin]

Hey Ikai,
  I only had one or two burst of them I noticed this morning.  Noticed
this on two apps once around 10:30 eastern time, and again around
12:30 eastern.  Both time it seemed to last under 5 minutes.  In both
cases my apps were serving traffic with multiple instances.

  Both times I also noticed appspot.com acting funny (very slow) too.


  Aside from that my apps have been supercharged since Saturday.
Props to the AE team. very nice work.

Robert

Re: [google-appengine] Re: The request to API call mail.Send() was too large.

[Ikai Lan (Google)]

There's a 1mb limit on RPC calls in general. Did you try to send the email
to a large number of recipients?

What we need is a reproducible test case. If you have some code and some
attachments we can use to deterministically reproduce the error, we can
track this down.

[google-appengine] Re: The request to API call mail.Send() was too large.

[GK]

Each attachment is individually uploaded to the application and stored
in the datastore, so I assume that they are all less than 1mb.
However, it possible that an email can contain multiple attachments,
with the sum totaling more than 1 mb. I don't think this is the
problem, though, because I have successfully sent out emails that have
more than 1mb worth of attachments.

[google-appengine] Re: Video streaming working with tag, not with flash player ?

[Mark]

@John, thanks for the link, I believe I'm using the same techniques I
picked up from another writeup:

  
http://henriksjokvist.net/archive/2009/2/using-the-html5-video-tag-with-a-flash-fallback

The html5 video tag is working for me, it's just the flash player
isn't. When you are using the flash player, do you see your servlet
get requested for any byte ranges, or any other hints as to what
portion of the blob to fetch? For example, this is what my video get
servlet looks like:

  public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException
  {
String vid = req.getParameter("vid");
try {
  Video video =
PMF.get().getPersistenceManager().getObjectById(Video.class, vid);
  BlobstoreService blobstoreService =
BlobstoreServiceFactory.getBlobstoreService();
  ByteRange br = blobstoreService.getByteRange(req);
  if (br != null) {
// Works fine with  tag.
blobstoreService.serve(video.getBlobKey(), resp);
  }
  else {
// Flash player never seems to request any data. I can try
forcing some down:
blobstoreService.serve(video.getBlobKey(), new ByteRange(0, 0
+ 1024 * 256), resp);
  }
  }

So I can force some info down (horrible idea) and I'll at least see a
few frames render in the flash player, but that's the best I can get.
The player won't play any content.

I'll check out the link you posted which seems to do a more thorough
job than what I was referencing. I'm just curious to know if you
really got the flash player pulling or just the  tag?

Thanks

Re: [google-appengine] Re: Early Christmas Present from Google?

[Ikai Lan (Google)]

Hey everyone,

Thanks for the great feedback! Going forward, we're cautiously optimistic
about the datastore improvements. You should continue to code using best
practices - that is, don't assume datastore get() will always run in 5ms and
place make 200 get calls serially. We'll be watching the performance closely
in the meantime.

Re: [google-appengine] Dev app does not restart on code save

[Ikai Lan (Google)]

This is a Java app, correct? The server is *not* supposed to restart on code
save. What's supposed to happen is that if you have "Build Automatically"
checked, the code will be compiled incrementally as it is saved. If you
select "Debug as Web Application", this puts the JVM into debug mode which
will hot reload most saved classes.

Re: [google-appengine] Re: App Gallery no longer available

[Ikai Lan (Google)]

Hey guys,

Apologies for the delayed responses on this thread. The App Gallery was
something that was really awesome in App Engine's infancy, but App Engine
has since matured a bit and it's really not the best way to showcase App
Engine's capabilities. We've decommissioned it. If you're interested in App
Engine happenings, you'll definitely want to regularly check out our Reddit
page:

http://www.reddit.com/r/appengine

We should have better communicated our intents with this page. We're
unlikely to bring the App Gallery back. I'd personally love to see an App
Engine application that serves the function the App Gallery served, maybe
one that even uses the Prediction API (http://code.google.com/apis/predict/)
to sort out the spam and do rankings. If this is a project community members
are interested in taking on, let me know and I'll get you access to the
prediction API.

On a related note, due to the changes coming in Google Groups, we will be
porting the Open Source projects page as well as the "Will it Play" Java
frameworks page to our Project Hosting site:

Re: [google-appengine] incremental appcfg.py download_data

[Ikai Lan (Google)]

It is possible, but you will have to design a custom solution. Mark your
entities with an update timestamp and do downloads based on that field.

Re: [google-appengine] can appcfg.py upload_data but not replace entire matched entities?

[Ikai Lan (Google)]

I don't believe so. Entities are stored whole. They're not like database
tables where you can update a single column. The bulkloader turns your local
CSV entry into an entity and list of properties and saves that without
reading the current entity in the datastore.

Would it be easier if you could read your CSV file from the blobstore in a
mapper job? You'd have programmatic control over reading the existing entity
and deciding whether to modify it or not.

Re: [google-appengine] Lots of 500ers

[Robert Kluin]

Hey Daniel,
  I've been seeing periodic bursts of 500 errors for requests that
never reach my app (ie no requests logged).  Aside from that my apps
are running very fast, and I have not had any errors.

  Are you getting errors in your logs?

Sorry, but re-read the bullet point about the size limit increases.
Specifically the last sentence:

limited to 1MB in size."

Re: [google-appengine] First request on a new instance always has a status of 200 and an empty body

[Robert Kluin]

Sounds like you might want to look into how you are setting up your
app.  Are you using run_wsgi_app?

Are you doing any initial authorization checks?  That might be another
good starting point.

If possible you might want to post some code.

If you are using Python, try deploying with appcfg.py using the -v (or

Re: [google-appengine] Mystery data usage

[Robert Kluin]

Hi Erik,
  Several common sources of datastore stats / quota number funkiness:
 1) The numbers are not updated in real time.  Sometimes it can
take a day for the numbers to get updated.
 2) Because of 1, if you are using a session library (or something
similar) that create lots of temporary entities the numbers can
'appear' to be out-of-sync.

  I assume when you say switched to explicit indexes, you mean you
explicitly disabled indexing of any properties that do not need
indexes?

  Also, you might want to star issue 2740.

[google-appengine] Re: Video streaming working with tag, not with flash player ?

[John McLaughlin]

This site http://camendesign.com/code/video_for_everybody give pretty
much everything you need to know about setting up HTML5 video with
flash fallback,  I've been using variations of it serving video from
GAE Blobstore with no problem -- though I personally haven't tested it
beyond Firefox, Chrome, and Safari.  IE9 seems to be the HTML5
laggard, but the flash fallback should be OK for that.

One extra annoyance is that to take full advantage of the different
browser capabilities you need to create .ogv, .webm, and .mp4
transcodes of your video.  If thats more trouble than you want, you
might skip the HTML5 video and serve everyone Flash.  Note that to
serve Flash you also have to serve the "player.swf" file or equivalent
for them as well.

[google-appengine] Re: JavaScript Engine

[Pat Hawks]

Right.
I am asking specifically about Google Apps Script, makes reading from/
writing to Google APIs as easy as knowing the right functions, and
Acre, which is used to read/write Freebase data in Javascript.

I know it's possible to run Javascript on top of Java, but it would be
really great if this could be combined with the two APIs mentioned
above and run on top of App Engine.

Re: [google-appengine] _ah login page failing on devapp / Python

[Robert Kluin]

You might want to try installing and running with Python 2.5.  Seems
to clear up quite a few of these issues.

[google-appengine] RequestTooLargeError

[mattbeedle]

I'm having trouble with request size limiting, but I don't understand
why.  Im this blog post (http://googleappengine.blogspot.com/2009/02/
skys-almost-limit-high-cpu-is-no-more.html) and it seems to say that
the limits on requests and responses were increased to 10mb.  My
application receives emails and then forwards them on to a website I
run using urlfetch.  Whenever I send an email with an attachment over
1mb, I see these RequestTooLargeError errors.  Here is the actual
piece of code that is failing, the error is occurring on the response
= fetch line:

import logging, email, yaml
from django.utils import simplejson as json
from google.appengine.ext import webapp
from google.appengine.ext.webapp.mail_handlers import
InboundMailHandler
from google.appengine.api.urlfetch import fetch
from google.appengine.api.urlfetch import Error as FetchError

settings = yaml.load(open('settings.yaml'))

def callback(raw):
  result = {'email': {'raw': raw}}

  response = fetch(settings['outbound_url'],
  payload=json.dumps(result),
  method="POST",
  headers={
'Authorization': settings['api_key'],
'Content-Type': 'application/json'
  },
  deadline=10
 )
  logging.info(response.status_code)
  if response.status_code != 200:
raise FetchError()

class InboundHandler(InboundMailHandler):
  def receive(self, message):
logging.info("Received a message from: " + message.sender)
callback(message.original.as_string(True))


It would be great if someone could explain to me why this is not
working and how I can get around it, thanks.

Re: [google-appengine] JavaScript Engine

[Robert Kluin]

Well, there are other people who would like to see JavaScript.  Using
Java it is already possible to run JS on GAE, issue 35 has some
details about how to get it setup and some of the limitations.  I am
not familiar with Google Apps Script or Acre, so I can not tell you if
those will run or not.

[google-appengine] First request on a new instance always has a status of 200 and an empty body

[David Rocamora]

Hi,

I'm working on a project that consists of a REST service that's
running in GAE. It's simple and written in Python with the webapp
framework. I've noticed a problem where the first request to the
application always returns an empty body with an HTTP status code of
200. I'm seeing this problem in both the dev server on my machine and
when the app is uploaded to GAE.

The app has just one get method and one post method. These are used to
add and view things in the datastore at the URI that the client is
accessing. If the data is not in the data store when a client tries to
GET it, the app should return a 404 and no body. If the data is there
it should return the data in the body of the response with an HTTP
status of 200. A POST works similarly; HTTP 200 with some data in the
body if we can update the datastore and a 500 error if there was a
problem. This works after the first request to the dev server or an
instance, but the first request is always returned with an empty body
and a status code of 200.

This happens with a GET or a POST to a known good URI or even to a
completely random URI that should be a 404.

I have tried to debug this by using logging to see where the app is
getting hung up, but strangely enough it doesn't even seem to be
executing my code on the first request. Is there anything I should be
looking out for here? How can I troubleshoot this?

Thanks,
Dave

[google-appengine] deploy failures

Is anyone else experiencing this behaviour? Is there a way to

[google-appengine] Mystery data usage

[Erik]

Hello all,

I have been uploading a dataset which is composed of 100MB of CSV
values.  During the process of uploading with bulkloader, which never
completed, the datastore expanded to consume 2GB of usage.  I decided
to explicitly index my data and clear the datastore before a re-import
using the blobstore/mapreduce method.  However, after clearing the
datastore there is still a persistent .37GB of data usage remaining,
while datastore statistics say 53KB is being consumed by 174 objects,
and nothing shows in datastore viewer.

Any ideas on how I can recover the .37GB of quota which is
mysteriously being used in my empty datastore?

Many thanks,
 -Erik

[google-appengine] Dev app does not restart on code save

[jesbox]

Hi,
Just working through the tutorials under Eclipse. The app is supposed
to restart when any code file is saved, but this does not happen to
me.

Further, I do not find any knob to do it manually. The "Servers" tab
is empty, so this kind of app does not run in a web server.

Any tips?

[google-appengine] Video streaming working with tag, not with flash player ?

[Mark]

Hi,

I'm doing some work with the blobstore and videos. I've gotten it to
work (was pretty easy) when using the  tag, something like:

  

  

Some browsers support the video tag, and my servlet which serves the
videos sees byte ranges specified from the client browser.

Because not all browsers support the  tag, I was wondering if
it is wiser to switch to a flash video player instead. When I try
that, the flash player does not present any requested byte range to
the servlet. It seems that the flash player just doesn't support that,
and I was recommended to use progressive download or RTMP - but I
don't know if app engine supports either of those.

Has anyone else got streaming with flash working from the blobstore?
Would be fine going with the  tag but not sure if it's really
well supported yet,

Thanks

[google-appengine] The request to API call mail.Send() was too large.

[GK]

Hi,

My app threw an exception because apparently The request to API call
mail.Send() was too large. Could someone please explain what quota it
exceeded and if there is a way to get around this (either by better
coding or by paying google)

My app needs to send emails with image attachments. The size of these
attachments is up to the users.

Thanks

[google-appengine] deleting the blobstore

[andreas schmid]

hi,

is there a way to delete all blobs in the blobstore without the need to do it 
manually batch by batch?

it would be a nice feature on the side of the datastore_admin.

[google-appengine] Re: How to add Google App Engine application to users Google Apps dashboard

[bengroot87]

Is there any other way to make te App simply available for all users.
Maybe the Google menu like the "Universal navigation: add yourself to
Google's menu" mentioned on this page:
http://code.google.com/intl/nl-NL/googleapps/marketplace/#benefits.

[google-appengine] Re: Early Christmas Present from Google?

[Julian Namaro]

Back in July, and even after a maintenance before that I noticed a
significant lower latency in the few days right after the maintenance.
It never last though, so we should probably wait a few more days
before assessing the results. I wonder what kind of changes in
BigTable could cause a temporary improvement...
