If you want to rule out your network connection this is a good way to do
that... Even if it won't test super fast connections with perfect accuracy,
your connection should always score about the same.  I have found that I get
some drastically different results on my home 20 meg Comcast connection at
different times of the day compared to testing from my colo's rack, where as
Speak easy always tests the same (I suspect that Comcast has figured out
that giving priority to speed tests is good for blaming other people for
their problems...

 Hello,

 My application (ID: jacob-6) seems to be performing worse after the
 maintenance of yesterday.  I have not made any significant changes
 that would  affect performance to this degree, but I definitely see a
 change since yesterday.  Requests are taking much longer and is
 unpredictable.  For example, look at the following two requests.  Both
 for the exact same information, doing the exact same processing.  The
 times are very close since I ran the request manually.  The first took
 much longer to process.

 This behavior is happening across all my requests.

 I'll try it from a different network connection when I go home

 Any ideas?  My app went from pretty snappy to pretty slow overnight.

[google-appengine] Special HTTP request header for task queue

2009-09-03 Thread James


The 'X-AppEngine-Cron' header is useful if we don't want to use the
app.yaml to define admin privileges, but still don't want just anyone
hitting protected URLs.

It doesn't look like there's an equivalent for tasks. Is this true?

Hi Carlos,
The short story is: We won't lose your data - we have a robust backup and

so we suggest you keep your own backups so you can recover from bugs or

 You can probably trust Google's infrastructure to not lose your data;
 however, it's a good idea to make backups in case software problems in
 your own code cause data loss.

[google-appengine] Re: 30 Max simultaneous requests (maxThreads)?

Hi Adligo,
The limit on concurrent instances of your app is not a hard one - it will
increase as your app gets more traffic. The only situation you're likely to
run into it is if you have a lot of requests that take a long time to
complete - eg, if you're calling time.sleep() in your request handler. As
long as you're serving your requests reasonably efficiently, you can expect
the number of concurrent requests your app is allowed to scale up with load.

 Hi,

   I am developing a app (or more than one) that I would like to host
 on Google App Engine, however the architecture of the app involves
 cranking up the maxThreads (I am using my home grown hosting which now
 has Tomcat set to 2,000 maxThreads :) ).

 For example (1 six+ year old machine in my basement)
 http://zeuhl.adligo.com/gwt_util_demo_v3_1/GwtDemo.html?show_log=true

 I was reading somewhere that my app will be limited to 30 Max
 simultaneous requests (maxThreads), and I didn't see anything about
 being able to change this (EVEN IF YOU PAY FOR IT).

 So is it possible to change this?
 If not why, it should be billable like everything else...
 How much would it cost?

 Also I think that it seems like a silly limit (although probably a
 good starting point for most apps).   Some apps need a lot of threads,
 some have a lot of page requests.
For instance my app needs a lot of threads (the above version uses
 at least 1 per user ALL THE TIME) and will go to 2 per user in the
 next release :) Or rather to be more specific One thread per open
 browser window, so I can 'send' data to the browser window in near
 real time with out having the browser window send a request every
 millisecond (which causes other problems).
 So it will be limited to 15 users on Googles App Engine yikes!

 Cheers,
 Scott

[google-appengine] Indexes stuck in 'Building' state. Cannot vacuum ('because they no longer exist')

Hello!


I have two index stuck in 'Building' state, for the past 12 hours. I
still have entities in the datastore, but they should have finished
building by now. I can't vacuum them with appcfy.py because it says
they are no longer there. I see the 'trend' is to ask one of guys to
help me out vacuum the indexes (my application id is 'cosinux68'). But
why don't you implement a force clear indexes' feature? :)

[google-appengine] Re: Problem with authentication services

2009-09-03 Thread Dario


Yes, I was logged with one of the google apps accounts for the domain
defined in the config.
I've attached both the LOG and the part of the code that sent the
exception.

You can see that the row that throws the exception is row 87,
corresponding to the following code: userService.createLoginURL
(thisURL). The contents of thisURL is the url /LoginServlet
mapped back to the same servlet.

I tested the appplication both logged and not logged in, and
inexplicably the error is always at row 87. It seems that the
statement request.getUserPrincipal() always returns null. Maybe
there are two problems here ...
thanks

Thanks a ton Nick. I do delete the data in batches. The problem is not
so much with delete. I can always restart the deletion process and
clear out all the data. The problem is with uploading.

I tried uploading in batches of 100 (lines in the csv file). Then with
50. None of them worked. How do I rate-limit the upload to a slower
speed?

Also, I think the appcfg.py with the upload data option tackles this
problem of restarting the upload process from wherever it crashes
last. I am getting some errors in that too. Can you help me with that?

[google-appengine] Re: Request file size limit?

2009-09-03 Thread Andy Freeman


It is odd to suggest that maximum request size implies something about
scalability.

For example, the Google search api (the one that uses the search
engine) has a 2KByte size limit.  The search box itself has similar
limits.

If I write a simple text comparison program that allows 1MByte
queries, would you say that said program scales more than Google
search?

If Google changed the search limit to 10KByte, would you say that
they'd made search more scalable?  Would changing it to 500 bytes mean
that it was less scalable?

[google-appengine] Use Transaction for DataStore operation?

2009-09-03 Thread Dave


My app generates a unique id string for each user who registers (like
a tinyurl). The id is based on random numbers, which are seeded from a
hash of their user information. There are over 240 million
combinations possible for the id, but I want to avoid collision by
checking against the datastore first to make sure a user with this id
doesn't already exist.

While it's unlikely to happen, I see a potential race condition if 2
users register at almost the same time, and their user information
hashes the same id. It's possible that both could check the datastore
for id uniqueness before either has inserted the new record, and as
such I could end up with two users in the datastore with the same id.
Unlikely, but possible.

Could I resolve this with a transaction, by making the lookup and
subsequent insert a single transaction? Or would this not really
resolve the issue, as a transaction's view of the datastore is frozen
at the start of the transaction (so I wouldn't see the other record
just inserted). If a transaction isn't the way to go, can you
recommend a method to get out of this race condition?

Thanks,
Dave

I tried the tests from two locations now.  Same results on the poor
performance.  I profiled the app. but found nothing obvious.

Is there a way to download all the profile data?

Some of my requests are now taking 11000ms.  However, the same request
a second time might take only 400ms.  I'm at a loss.  I'm only
fetching 25 from the first page.

action_gql = Action.gql(WHERE project = :1 and state = :2 and
archived = :3 and milestone = :4 ORDER BY state DESC, due ASC,
priority DESC, summary ASC, project_key, 0, False, db.Key(milestone))

This is an example query.  Possibly the ORDER BY?

 I uploaded my code (both production and latest) to a new application

 out all datastore touches from the code on the broken instance to see
 if that was the issue, it wasn't.

 If you look at the stack traces they appear to be happening during

 I do appreciate the input though, it is good advice.

  Always have two copies of your application, so you don't risk corrupting
  your live data.  

  Make sure you only have one guy with the rights to deploy to your primary
  app so that a momentary lapse in Yaml configuration doesn't bork your site.

[google-appengine] Re: Use Transaction for DataStore operation?

2009-09-03 Thread John Newlin


Looking at the create_or_update function here:
http://code.google.com/appengine/docs/python/datastore/transactions.html

It would seem that transactions will do what you want.  In the else:
clause where they do the update, you would probably want to change
this to throw an exception.

If this didn't work, then it'd be possible to create 2 duplicate
records, which would seem to defeat the purpose.

 Hello,

 I am a newbie to Datastore.  Here's what I am trying to accomplish:

 Trying to set an Unowned one-to-many relationship between 2 objects. (I
 chose unowned because I wasn't sure if I could have an owned
 many-to-many.  Also wasn't sure if lazy loading is available for the
 children.  Is owned the recommended way?)

 Anyway, I have a *Parent *class in which I have this...

 @Persistent
 private SetKey children = new HashSetKey();

 In the *Child *class I have this...

 @Persistent
 private Key parent = null;

 I am doing the following:

 1)  Create a Parent.. This worked.  The parent.getId() gives me the Id.
 2)  While creating a child, I want to attach the child to parent, so I
 tried several variations such as this:

 String parentId = parent.getId().toString();
  child.setParent(KeyFactory.stringToKey(parentd));

 This is NOT working.  What's the best way to do this?

 3)  Also, I need to put the key of child into Parent.  As per, Max Ross'
 presentation at Google I/O this doesn't work in the same transaction.  Has
 that issue been fixed?

 Is there any tutorial available that shows this?  Any help in this regard
 will be greatly appreciated.

 Thanks.

I guessed it had something to do with Jasper. So I entered the

There I deleted files repackaged-appengine-jasper-compiler-5.0.28.jar
and repackaged-appengine-jasper-runtime-5.0.28.jar. Then I downloaded
Tomcat (version 6.0.20) and I found in it files jasper-el.jar,
jasper.jar and tomcat-juli.jar. I copied them to google_app_engine/
appengine-java-sdk-1.2.2/lib/shared/jsp.
After that error dieappeared.

Have any of you encountered problem like that?

[google-appengine] Transaction collision Retries

2009-09-03 Thread vivpuri


I am getting the following error for get_or_insert


Transaction collision for entity group with key
datastore_types.Key.from_path(..)


and then the code goes into a loop where it keep retrying until the
app hits DeadlineExceededError.


So there are couple of major issues:
1. The whole request took  38113ms to complete before hitting
DeadlineExceededError. Since transaction collision can happen for
multiple app request at the same time, this can quickly consume all
the available app instances.
2. Also, as part of this app request, i was trying to insert 5
records, and app got hung up on the first record itself. Which means
rest of the records got dropped

Solution needed:
A way to break this retry loop so that next records can be processed

[google-appengine] Queue Rate

2009-09-03 Thread vivpuri


In my queue.yaml i defined couple of new queues, besides the existing
default queue. For each of these new queues i tried setting the rate
to 10/s. On uploading the app i received an error that my rate was
20.0, whereas the max allowed is 10/s. Would this limitation be
removed when appengine goes live with billable tasks/queues?

Also current this limitation does not throw any error anywhere on
localhost. Or maybe it does but i dont know where to look for.

[google-appengine] Re: 30 Max simultaneous requests (maxThreads)?

2009-09-03 Thread Adligo


Hi Nick,

   I am not calling sleep but I am using a server side
ArrayBlockingQueue, with methods like
queue.poll(waitTime, TimeUnit.SECONDS);
  So I am not buffering but simply responding with current messages
and if there arn't any waiting until some show up and then
responding.  If no messages show up in 20 seconds or so I respond with
a empty message list and then the client sends a new request.

I am using GWT's rpc, here is my service api, which is open souce.
http://cvs.adligo.org/viewvc/gwt_util/src/org/adligo/gwt/util/client/rpc/MessageService.java?view=markup

So I am anticipateing that I will have a lot of threads that are
simply waiting on the ArrayBlockingQueue's poll method.  This allows
me to do things like;
1) send log messages between two browser windows
2) send system messages from a admin console to anyone viewing the app
like;
  (System is going off line in 10 minutes)
  (There is pizza in the lobby for anyone who wants it)
  exc
3)  Implement a IM client in the browser
4) Send 'event' data between browser windows so a user can click a
button in one window
 and have it do something to another window.   Currently the only
application of this is to
reload the adligo_log.properties file, so you can change your log
levels at runtime.  However
there are a lot of other applications for this, windows can now
communicate.

Also there shouldn't be much of a drain on the processor, since most
of the threads are simply waiting (not doing a lot of processing).  It
just requires a large number of threads (one per browser window).

Cheers,
Scott

PS I would really like to host on Google Apps, the server
http://zeuhl.adligo.com/gwt_util_demo_v3_1/GwtDemo.html?show_log=true

 Hi Adligo,
 The limit on concurrent instances of your app is not a hard one - it will
 increase as your app gets more traffic. The only situation you're likely to
 run into it is if you have a lot of requests that take a long time to
 complete - eg, if you're calling time.sleep() in your request handler. As
 long as you're serving your requests reasonably efficiently, you can expect
 the number of concurrent requests your app is allowed to scale up with load.

  Hi,

    I am developing a app (or more than one) that I would like to host
  on Google App Engine, however the architecture of the app involves
  cranking up the maxThreads (I am using my home grown hosting which now

  For example (1 six+ year old machine in my basement)
 http://zeuhl.adligo.com/gwt_util_demo_v3_1/GwtDemo.html?show_log=true

  I was reading somewhere that my app will be limited to 30 Max
  simultaneous requests (maxThreads), and I didn't see anything about
  being able to change this (EVEN IF YOU PAY FOR IT).

  So is it possible to change this?
  If not why, it should be billable like everything else...
  How much would it cost?

  Also I think that it seems like a silly limit (although probably a
  good starting point for most apps).   Some apps need a lot of threads,
  some have a lot of page requests.
     For instance my app needs a lot of threads (the above version uses
  at least 1 per user ALL THE TIME) and will go to 2 per user in the
  next release :) Or rather to be more specific One thread per open
  browser window, so I can 'send' data to the browser window in near
  real time with out having the browser window send a request every
  millisecond (which causes other problems).
  So it will be limited to 15 users on Googles App Engine yikes!

[google-appengine] Google Analytics and GAE

2009-09-03 Thread Brian


To any Google people that are listening:

Please add support for Google Analytics. It would be great if you
could provide your Google Analytics key in the GAE console.

When a script receives a query, it would echo data through to Google
Analytics (e.g. IP address, HTTP headers, etc).

While you can embed the Analytics tracker Javascript in a HTML page,
this doesn't work if you're tracking API calls, serving non Javascript
pages (e.g. mobile devices, etc). This way you'd be able to run
consolidated usage reports on all types of traffic (web, mobile, API
calls, etc).

Consider using -a 0.0.0.0 on the dev_appserver commandline. This will
bind to ports other than localhost.
You may be able to get fiddler to proxy 127.0.0.1 but it's probably
easier to use your own machine name and the -a flag.

[google-appengine] Re: CPU Quota

2009-09-03 Thread Jeff S (Google)

Hi Cornel,

One possible cause that the data upload might be more expensive the second
time around is if you had created indexes after the initial upload. If you
have a large amount of data and your application is not yet being used, it
is often best to upload the data, then create indexes. The index creation
time might be longer, but you'll save on API CPU cost. This is just one
possibility, I think I'd need to know more about your application.

Thank you,

Jeff

[google-appengine] Upload local datastore content to App Engine

2009-09-03 Thread FolkenDA


Hello everyone,

I'm new to GAE and I am currently trying to move a website of mine to
this platform.

re-write the PHP code into python was really easy. However, I'm now
trying to move data from an mySQL database into the GAE datastore.

I was previously storing images in a directory in the server file
system, so I successfully wrote a script that fetch them and store
them in the local datastore.
The script works in dev server because they have no timeout, but the
GAE servers do.

I tried to download the local datastore into CSV files that could be
uploaded using the bulkloader method but got the following error:

AssertionError: No api proxy found for service datastore_v3

I guess dev servers do not emulate this functionality.
Is there some way I could use to upload local datastore to the
production one ?

Thank you,

Folken

[google-appengine] Text based RPG

2009-09-03 Thread Matthew Kramer


I'm really new with python and google appengine and I'm still trying
to figure out how to work things with it. I'm going to try and make a
text based rpg and I was wondering if anyone could give me some
pointers and easy ways to get me started.

Thanks for any help given :)

[google-appengine] Verification SMS not received

2009-09-03 Thread Damian Parrino


I have a problem with Verify Your Account by SMS page.

Does anyone know how to verify one's account if you are living in
Argentina and using Movistar as carrier?

I entered my number in the format required (it was validated ok), and
the SMS was sent as stated on the screen, but I never received the SMS
code.

I tried many times with no success. There's any other way to verify my
account?
thanks in advance,

regards,
Damian

[google-appengine] Re: Upload local datastore content to App Engine

One of the new features of today's release is a --dump and --restore
flag in the bulkloader, allowing configurationless download and
restore of a dataset. It should work for exactly this scenario: you
have data in one instance (say on dev_appserver) and want to upload it
to another (say on appspot.com).

You can find more information at
http://code.google.com/appengine/docs/python/tools/uploadingdata.html#Downloading_and_Uploading_All_Data

I'm not sure about the datastore_v3 error, but it may also be
something we fixed.

Hello everyone,

I'm new to GAE and I am currently trying to move a website of mine to
this platform.

re-write the PHP code into python was really easy. However, I'm now
trying to move data from an mySQL database into the GAE datastore.

I was previously storing images in a directory in the server file
system, so I successfully wrote a script that fetch them and store
them in the local datastore.
The script works in dev server because they have no timeout, but the
GAE servers do.

I tried to download the local datastore into CSV files that could be
uploaded using the bulkloader method but got the following error:

AssertionError: No api proxy found for service datastore_v3

I guess dev servers do not emulate this functionality.
Is there some way I could use to upload local datastore to the
production one ?

Thank you,

Folken

[google-appengine] Re: running a long process once


The typical answer is to split up your operation.
You solve this particular problem in a few ways:
 * Split the data--if it only takes about 30 seconds to parse your
entire file, then splitting it into two should easily get you under
the 30 second limit on the server. Do note that the performance
characteristics of the datastore are quite different on the server
than in dev_appserver.
 * Use remote_api -- write your translation tool with remote_api in
mind and run it locally but pointing at your production datastore.
 * Use the bulkloader -- effectively the same thing, wrapped in some
code which handles backoff and such for you. However this may be
difficult.
 * Run it locally, importing into dev_appserver, and use the new --
dump and --restore feature of the bulkloader to move the data to your
app on App Engine.

[google-appengine] Re: running a long process once

Another option is to use task_queue on the server. Upload your entire
file (either as a string to your datastore, or as source code if it's
a one time operation, or use urlfetch to retreive it into memcache or
similar). Then process it line by line with the task queue API.

I'm not a google employee or a lawyer, but the intention is you can't take
10 free accounts, to get 10 gigs of download a day, instead of having 1
account which would pay $1.20 a day for that same download capacity.

If it is/will be possible to pay to get more GAE apps, then having
multiple iPhone apps use the same GAE app is a way to avoid incurring
fees.

Segment the import, then import in sections.  Ie Rows 1-500 then rows
501-1000.

You might also use your local machine running the code to talk to the remote
app in baby steps

Parse data to new format, Post to GAE App, GAE app Writes to GQL or where
ever... Rinse, repeat.

Common types are adventure, world, place, actor, thing, player, view,
command, and prioqueue. We may view an adventure in a view in a world
looking for some special thing. Important are both classes ie thing
