[google-appengine] "Request was aborted after waiting too long"

[Benjamin Schuster-Böckler]

I'm getting loads of these. It's ok with the deferred tasks, as they are 
rescheduled, but the cron jobs (to be run every 10min) just don't run if this 
happens, causing unpredictable behaviour of my app. Effectually, the cron only 
runs eery few hours, because most of the time, this error occurs. What can I do 
to fix this? Do I really need to have a dummy task to constantly hammer 
instances so the app stays loaded?

Thanks in advance,
Ben

[google-appengine] Cannot create additional applications

[chris]

Hello,

Although I successfully created/uploaded/deployed my first application
yesterday, when I now try to create a new application from the "My
Applications" page (at either appengine.google.com or
appengine.google.com/a/mydomain.com), I am redirected to the "Verify
Your Account by SMS" page (https://appengine.google.com/permissions/
smssend). As I have already received my SMS, entering my country/
provider/phone number generates an error, so I can't proceed.

Also odd: although I have an application running, and another that
I've disabled (both created yesterday), the "My Application" page
states: "You have 10 applications remaining."

A possible contributing factor (?): I have two Google accounts.

I'm aware that problems similar to the one I'm experiencing have shown
up on the list a number of times, but I've yet to see an answer that
seems to resolve the issue in a general way. Please correct me if I'm
wrong here (and there is, in fact, a thread that provides a solution).
At any rate, help would be appreciated.

Thanks in advance,

Chris

[google-appengine] Error code 203

[Graph]

HI Guys,

recently I began to receive  warning message  :

A serious problem was encountered with the process that handled this
request, causing it to exit. This is likely to cause a new process to
be used for the next request to your application. If you see this
message frequently, you should contact the App Engine team. (Error
code 203)


why this situation may arise?

Thank

[google-appengine] How can I keep my password long time for updating content?

[SuperNova]

Now when I run this command:

/usr/bin/python ~/google_appengine/appcfg.py update ~/cdn

I should write email and password.
And it is keeping some time, but after a day, I should write email and
password again.

How can I keep my auntification (email and password) for long time
(month, year)?

[google-appengine] Request was aborted after waiting too long...

[Mikkel Krautz]

Hi,

My app at alsmicdk.appspot.com has been getting the following error:

Request was aborted after waiting too long to attempt to service your
request. This may happen sporadically when the App Engine serving
cluster is under unexpectedly high or uneven load. If you see this
message frequently, please contact the App Engine team.

for the last couple of days now.  All requests for dynamic pages (i.e.
script handlers), are getting the error. I'm on the Python runtime,
BTW.

I've tried to determine if anything's wrong on the app side of things
(if certain API calls were causing the long request time) by uploading
a new version of the app ('recovery'), but even simple request
handlers that make no API calls are failing.

The app is, in its usual condition, set up to only allow for HTTPS
connections (secure: always). I figured this might be the cause of the
long request times, but I've also tried to change it to (secure:
optional) in my 'recovery' version to no avail.

Any help?

Mikkel

[google-appengine] ssl connection mutual authentication

[Steve favez]

Hello,

I'm trying to consume a web service (using URLFetchService) through
https, requiring a mutual SSL authentication. (soap ws, using axis2
with custom HTTP Transport layer, using URLConnection -

Without HTTPS, everything works fine.

use my own keystore for SSL mutual authentication. :

[google-appengine] GPL but not 'open'

[Prof. Ebral]

I am a little curious about Google approaches an app on there page
that is designated as GPL, but the current developer wont release the
code.

When I say 'current' developer, I am not implying the 'original'
developer(s) either. Just some guy that has developed for the GPL
software. The application in question can be found here: 
http://orpgmeta.appspot.com/
and is the meta server list for the OpenRPG Project's virtual game
table.  The meta server has been broken for nearly a week now with no
response from the holder of the appspot page.

Well, Just because it's GPL doesn't mean that you have to give the
sourcecode to everyone. Just that you can't put any constraints on it
once you give the application or the sourcecode to someone. So you can
build software, put it under the GPL and never give anyone the source,
as long as you use it only for yourself and don't give other people
(customers or just other people who would like to use it). As soon as
you do, you have to give them the sourcecode or at least give them the
necessary informations how they can get it. (Most endusers don't care)

When you are just a user of the app that he installed there you have
no additional right.

[google-appengine] Re: Total Stored Data - can someone explain please ??

[Perica Zivkovic]

Nick,

this is the data stored - 347 entities

Breakdown by Property Type

Property Type   Size

Blob 3 MBytes
String   24 KBytes
Date/Time9 KBytes
Text 7 KBytes
Integer  7 KBytes
Key  3 KBytes
Boolean  598 Bytes
BlobKey  178 Bytes
Category 18 Bytes
Metadata 63 KBytes

Additional three blobs in the blobstore, two of them are images/jpeg
(total 8mb) and one video/flv - another 8MB total in blobstore 16MB

I think someone @ Google did some magic because now after couple of
days without any modifications from my side my app is using 0.02 of
101 GB of Total Stored Data. That is exactly 20MB like it should be
and not 550MB like it was.

Any explanations on this one and what was going wrong ??

cheers,

Perica

You must have many properties on your entity, otherwise Metadata
wouldn't be so large.

And I think most of your properties are indexed, it's very reasonable
why it takes so many space.

[google-appengine] Tasks queues not working?

[dan]

Our tasks stopped running last night around 7pm pacific.

Currently tasks are piling up in our queues, although we are still
well under quota (API calls 0%, task count 4%, task bytes 8%).

However, it's only a certain type of task! That is, we have a common
task that is not running, but a rare task (hourly) that still is.

Is anyone else having weird problems with tasks executing from the
queue?

[google-appengine] Memcache not working

[Denis]

Hello,

Memcache stopped working for my app at some point on May 4. And on May
5 it still not functioning.

All memcache.set(...) calls return False today. I tried to upload new
versions, change key names - to no avail.

The value I'm trying to store is a very short string (6 characters
long) so it shouldn't be a matter of insufficient memory.

The code that works with memcache is heavily used by my app and it
works without any changes for more than a year now. Moreover, the
current version has been working for the last couple of weeks and
there have been no such problems before yesterdays, so I assume it's
not a bug in my code.

System Status page doesn't report any memcache problems, so I wonder
why my app can't use memcache?

[google-appengine] Re: GPL but not 'open'

[samwyse]

Go read this:  http://en.wikipedia.org/wiki/Affero_General_Public_License

The AGPL was designed to close a perceived application service
provider "loophole" (the "ASP loophole") in the ordinary GPL, whereby
when using but not distributing the software, the copyleft provisions
are not triggered. The AGPL differs from the GNU GPL on which it is
based in having an additional provision addressing use of software
over a computer network. The additional provision requires that the
complete source code be made available to any network user of the AGPL-
licensed work, typically a Web application.

IANAL, but it's plausible that if one were to upload GPL software to a
service provider, the provider would have a right to the source.  Then
you'd just need to convince the provider to share the source with
you.  Whether the App Engine crew would be willing and able to assist
in this way is an open question.  I wouldn't hold my breath, however.

[google-appengine] Re: ssl connection mutual authentication

Hi Nick,

thanks for the quick reply.

Do you plan to add this feature in a future release ?

Otherwise, what do you think to use secure data connector as a
proxy. ??? ... (kind of workaround if I really need to call a web
service requiring ssl mutual authentication.) ?

Thanks

[google-appengine] send_mail sender restrictions and Google Apps Premier

[Brandon Bloom]

Hi,

My app sends and receives mail on a variety of @mydomain addresses.
These addresses are Google Apps user accounts, but after initial
setup, all of their mail is forward to an appspotmail address and
these users never login. I set it up this way due to GAE's send_mail
sender restrictions [1].

I am considering upgrading my Google Apps Standard account to Google
Apps Premier. While there are only 2 actual human accounts, there are
half a dozen dummy accounts to satisfy Google Apps. These accounts
would cost me $50/year each if I were to upgrade. I have not yet tried
making only a single dummy account with various aliases (nicknames?),
but that would still cost me $50/year for the fake user account.

I contacted the Google Apps sales team, but they said that they do not
provide free or "standard" accounts on premier domains
(understandably). They suggested that I contact the Google App Engine
team to see if there a suggested workaround.

Is there a workaround?

Thanks,
Brandon Bloom

[1] "The sender address can be either the email address of a
registered administrator for the application, or the email address of
the current signed-in user (the user making the request that is
sending the message)."

The capabilities API is not returning as expected :(

More specifically

datastore_write_enabled = capabilities.CapabilitySet('datastore_v3',

During this maintenance period, datastore_write_enabled is True

If you guys could please set it to False (I can't deploy to fix it)
that would be MUCH appreciated.

[google-appengine] Re: * TIME SENSITIVE * Capabilities API is not working during downtime

[Greg]

*** SECONDED ***

Well done to the team for the shorter than usual maintenance outage,
BUT COME ON GUYS... our customers and their customers get 500s instead
of the outage message - I'm livid.

We try to manage customer expectations about these outages to limit
the damage they do. We send out warning emails to customers, and then
show an outage message explaining what is going on (and that they were
warned about it). Except our customers get server errors, and we look
like LEMONS.

Now we're going to have to go away and write our own capabilities
test, because we can't trust yours. And if we can't trust the
capbilities API, it raises questions about what else we shouldn't be
trusting. Appengine is predicated on trust - users trust Google can
run the service better than we can.

I have no idea how the capabilities API works - it obviously isn't
automated, so I'm guessing someone forgot to change the settings. One
tiny task missed off the checklist - wait, you did have a checklist,
right? See how that one tiny task has got me questioning your whole
operation.

I love the Appengine concept. But for it to succeed, you have to win
trust, and to do that you have to get everything EXACTLY right. If you
don't have a seriously anal project manager running these maintenance
outages, get one.

[google-appengine] Re: Memcache not working

[nickmilon]

May be this is releavant ? :

Reminder: there will be a scheduled maintenance period for App Engine
TOMORROW, May 5th, at 1:00 PM Pacific Time (PDT) for up to one hour.
The datastore will be in read-only mode during this time period; all
datastore writes and transactions will throw an exception.

During this scheduled maintenance, memcache will also be disabled.
Calls to the memcache API will not throw exceptions but will instead
return False for set() calls and None for get() calls (just like any
other cache miss). In addition, memcache API calls will return
immediately during this period, without any additional latency.

[google-appengine] Datastore related question - fetch random records

[Ankur]

Hello All,

I have a datastore related question. Here is the scenario:

* I am keeping a master table which has all the records and each
record has a unique id.
* For a given category (e.g.- male or female), I want to fetch N
random records from BigTable.

What are the ways to achieve this? I want true random numbers and not
in sequence. e.g. ids with 110,540,2111,6,4005,100 etc.

To make this problem a little bit more complex, I want to fetch N
random records for multiple categories. Few examples:

* Select N random records where category=male AND location=london
* Select N random records where category=female AND location=seattle
AND category=celebrity  (if the solution for this use case it complex,
then I can ignore it for the time being)

Any ideas from GAE community will be very helpful.

Thanks,
Ankur

[google-appengine] Re: Tasks queues not working?

[dan]

Tasks started executing again just an hour or two.  So, we had an
unexpected, unexplained outage of about 8 hours in the ability to run
tasks, with no quotas exceeded and no error logs.  That sucks, but I
don't know how to find out any more about it.

[google-appengine] Index error -- vacuum error, too

My app id is litl-developer-dev

First I got an error because I was missing the index for a query.

So, I added the index but that immediately caused an error and now the
index is in the Error state.

Trying to vacuum the index so I could perhaps recreate it, I also get
an error:

[google-appengine] GWT with GAE Blobstore

[Perugini]

I am trying to use GAE Blobstore with GWT. I have changed the sample
they have online:

http://code.google.com/appengine/docs/java/blobstore/overview.html

I replaced the jsp page with a GWT page (below). I replaced the call
to "<%= blobstoreService.createUploadUrl("/upload") %>" with a RPC
call which is initiated by "controller.getUploadURL("/index").

However I am getting the following error:

SEVERE: [127300268044] javax.servlet.ServletContext log: Exception
while dispatching incoming RPC call
com.google.gwt.user.server.rpc.UnexpectedException: Service method

I have installed GAE SDK 1.3.3.1. Any ideas will be appreciated.

[google-appengine] No 'Stay signed in' option for Google Accounts

[Anders]

When signing in to a GAE application with Google Accounts the 'Stay
signed in' option is only shown the first time a user signs in. For
consecutive sign ins the 'Stay signed in' option is missing. It would
be good IMO if the option was shown/available for all sign ins.

I doubt that, because it's your software that is running for you and
not for the service provider.
You have no contract with the service provider that grants him usage
of the software you are running.
It's the opposite in my opinion, which leads to the fact that the
service provider can't be considered
as "user" as the GPL means it.

But again, IANAL...
