[google-appengine] what tool would you use? ///My company needs a system that automatically sends messages to users to request their documents,

[j d]

My company needs a system that automatically sends messages to users to 
request their documents. and that users can answer whether or not they can 
claim them. then use that data to convert it into information. there are 
hundreds of users and hundreds of documents to deliver. I'm thinking of 
making an AI system that sends messages to people's cell phones, but I 
don't know what google clud tool to use.

[google-appengine] Re: App Engine Flexible Environment - Dockerfile installing outdated version of GDAL

[j o]

This is apparently happening as my app isn't running on port 8080 and App 
Engine is then crashing. How do I make sure that it is running on 8080? 

This is my app.yaml: 

EDIT:

My app.yaml:

# [START django_app] runtime: custom env: flex entrypoint: gunicorn -b :$PORT 
MyApplication.wsgi runtime_config: python_version: 3 # [END runtime] handlers: 
# This configures Google App Engine to serve the files in the app's static # 
directory. #- url: /static # static_dir: static/ #- url: /MyApplication/static 
# static_dir: MyApplication/static/ # This handler routes all requests not 
caught above to your main app. It is # required when static routes are defined, 
but can be omitted (along with # the entire handlers section) when there are no 
static files defined. - url: /.* script: auto # [END django_app] resources: 
cpu: 1 memory_gb: 2 disk_size_gb: 10

[google-appengine] App Engine Flexible Environment - Dockerfile installing outdated version of GDAL

[j o]

 am trying to use a Docker image on Google App Engine Flexible Environment.

FROM ubuntu:bionic


ENV PYTHONUNBUFFERED 1
ENV DEBIAN_FRONTEND noninteractive
ENV LANG C.UTF-8

RUN apt-get update -qq && apt-get install -y -qq \
# std libs
git less nano curl \
ca-certificates \
wget build-essential\
# python basic libs
python3.8 python3.8-dev python3.8-venv gettext \
# geodjango
gdal-bin binutils libproj-dev libgdal-dev \
# postgresql
libpq-dev postgresql-client && \
apt-get clean all && rm -rf /var/apt/lists/* && rm -rf /var/cache/apt/*

# install pip
RUN wget https://bootstrap.pypa.io/get-pip.py && python3.8 get-pip.py && rm 
get-pip.py
RUN pip3 install --no-cache-dir setuptools wheel -U

CMD ["/bin/bash"]




The docker image appears to build correctly but when the service deploys 
the application crashes and i get this error message:

 File 
"/Users/NAME/Documents/gcp/google-cloud-sdk/lib/googlecloudsdk/api_lib/app/operations_util.py",
 line 183, in IsDone encoding.MessageToPyValue(operation.error))) 
OperationError: Error Response: [9] 

Application startup error! Code: APP_CONTAINER_CRASHED ERROR: 
(gcloud.app.deploy) Error Response: [9] Application startup error! Code: 
APP_CONTAINER_CRASHED

This is failing as the Dockerfile is installing a significantly outdated 
version of the GDAL package which conflicts with the more current python 
installation.

How do I ensure that the dockerfile has the correct package repository and 
is installing the right, up to date, versions? Is there some line that I 
can insert to update the repository, or at least print the repository, 
before it starts installing?

Re: [google-appengine] Re: Why are cloud endpoints so slow ?

[J Jones]

Not sure if Google Endpoints are serious or not.  My appengine instance is 
warm and serving http request very quickly.  However, my endpoints are 
ranging from 3 seconds to 9 seconds... the endpoint just returns a 
hardcoded object so there's 0 happening there.  What a joke.

Re: [google-appengine] Re: Google App Engine community support is moving to Stack Overflow

-1 for moving to stackoverflow. Why do we need another site? I have been 
using Google groups for years, no issues so far. What do we get by moving 
to stakoverflow? Does it work on Android tablet or something else that we 
need to know that is so special about it?

Re: [google-appengine] Re: Outages?

[j]

Ikai,

I have not moved to HRD yet. But I am pretty sure I am the only user of my 
application. However, ever since couples of days back, not only that it is 
slow but I kept on running out of quota, despite the fact that I turned on 
the billing. I have switched off billing yesterday as it didn't help me.

Can I get a refund? The request is due to the fact that I am hitting the 
app less than 20 times per day, and I run out of quotas. Enabled billing 
didn't help. I am perplexed with a single user, how would it be possible to 
exhaust 0.05 million operations? see below as an example -

Datastore Read Operations
[image: 100%]
100%0.05 of 0.05 Million Ops0.00$0.70/ Million Ops$0.00

I don't want publish my appid, if you would like to know, I get text you at 
your google voice number. If that helps.

Thanks for any reply.

[google-appengine] Is external MySQL database integration possible with Google Apps

[Shaw J]

Greetings:

I am trying to figure out if the following is possible with Google Apps 
API's / SDK

We have a Php/Mysql application that we want to link to Google Apps 

(a) When we add a user in Php/MySql, we want that user to be added in 
google apps.  (The user name to be crea...@domain.name (not @gmail.com) ; 
the password for the newly created user;  the user name of an admin account 
that has the rights to create a user in that domain ; password for the 
admin account )

(b) There are two other pieces of user specific data in the Php/MySQL 
application that we want to display in users screen in Google Apps
This can be done as a batch process (if doing it in real time is 
challenging)
For example, in Php/MySQL, we can export the data into a format that that 
the google api can read and bring in as a google doc for that user in 
google apps.

Thanks SJ

[google-appengine] logging.error() messages don't appear in admin console

[J. Maurice]

Dear App Engine Gurus,

A few days ago, one of my python apps stopped logging all messages passed 
to the logging.{error,warn,info,debug} methods. Is there any limit or 
cutoff point where an app will stop logging messages? I even made a 
simplified test script just to test logging:

import logging
print 'Content-Type: text/plain'
print ''
print 'calling logging.info()'
logging.info(u'log test')
print 'OK!'

On the app in question, only the request line is shown, and no log is 
displayed:
[14/Dec/2011:14:19:30 -0800] "GET /hello HTTP/1.1" 200 73 - "Opera/9.80 
(Macintosh; Intel Mac OS X 10.7.2; U; en) Presto/2.10.229 Version/11.60" 
"app1.appspot.com"

However, if I deploy the same exact hello.py to another app, it logs 
without any issue:

[14/Dec/2011:14:26:33 -0800] "GET /hello HTTP/1.1" 200 72 - "Opera/9.80 
(Macintosh; Intel Mac OS X 10.7.2; U; en) Presto/2.10.229 Version/11.60" 
"app2.appspot.com"
I 2011-12-14 12:26:33.798
log test

Why would this happen for only one of my applications? Other applications 
log just fine in the admin console, but not this one.

Thank you...

J. Maurice

Re: [google-appengine] Re: How to determine datastore reads?

[J]

I agree.  As I originally posted, I'm having difficulty figuring out where 
the datastore reads are coming from.  I installed AppStats, and it shows 3 
"RunQuery"s and one "memcache.Get" per request.  So does this mean each 
request results in 3 datastore reads?  

Also, isn't memcache backed by the datastore?  So does this mean gets from 
memcache result in a datastore read?

Any have a better idea of how I can figure out where my datastore reads are 
coming from?

[google-appengine] Re: How to determine datastore reads?

[J]

Not really.  I have one COUNT query that is run during the aforementioned 
cron job (which runs once every 60 minutes now).  But the # of entities for 
that type is very low, typically between 1-10, so I wouldn't think the COUNT 
query would add too many reads.

Is there something about COUNT queries that I should be aware of?

[google-appengine] How to determine datastore reads?

[J]

Since GAE has released the comparison billing for the new pricing model, 
I've been trying to "optimize" my app to reduce costs.  I was initially over 
the free quota limits for datastore reads and writes.  I was able to lower 
the datastore writes to fall under the free tier by eliminating certain 
writes and also by eliminating unnecessary indexes on certain properties.

But unfortunately, I can't seem to figure out where the reads are coming 
from.  I initially thought the reads were mostly coming from two cron jobs 
that I have configured:

1) A job that ran every 1 minute to query for and delete "expired" objects 
for 1 of my entities.  
2) A job that ran every 1 minute to clean up old session entities.  I'm 
actually using the com.google.apphosting.utils.servlet.SessionCleanupServlet 
to do this (which I found somewhere online). BTW - is there a better way to 
remove old sessions?

I changed both jobs to run every 60 minutes instead (thinking this would 
make a huge difference) but my datastore reads are still high and not too 
different from previous numbers.

I've also examined my app (not a lot of code) and don't see where I could be 
making so many datastore reads.

Anyone know how I can profile my app to see where datastore reads are coming 
from?  BTW I'm using the Java version of GAE.

Thanks,
J

[google-appengine] How to get free tier?

[J]

Maybe I'm the only one but I find the new pricing page incredibly confusing 
to read: http://www.google.com/enterprise/cloud/appengine/pricing.html

It looks like there's still a free tier, but it doesn't include usage based 
pricing, infinite scalability, and SLA.  My question is how do I get the 
free tier?  Is this setting somewhere?  Or is this determined automatically 
by GAE?

If I use the free tier (once I figure out how), and it doesn't include usage 
based pricing or infinite scalability, what actually happens when I exceed 
free quota limits (in regards to usage based pricing) or if traffic spikes 
(in regards to infinite scalability)?

Thanks,
J

[google-appengine] Appengine prohibits accessing resources in jars?

[Alex J]

Hi everyone!

I'm trying to deploy my web app driven with Spring. My app spring
context configuration file references configuration placed in other
jars, like this:


http://www.springframework.org/schema/beans";
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
   xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd";>




- Where /spring/rcr-service-appengine.xml is a file in the separate
jar that is placed into the resultant war file.

While this war works fine on Jetty and on the local gae installation,
it failed to operate after being deployed on the appengine site.
The app log mentions the following error:


org.springframework.web.context.ContextLoader
initWebApplicationContext: Context initialization failed
org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
Configuration problem: Failed to import bean definitions from relative
location [service/appengine-service-config.xml]
Offending resource: class path resource [spring/application-
context.xml]; nested exception is
org.springframework.beans.factory.parsing.BeanDefinitionParsingException:
Configuration problem: Failed to import bean definitions from URL
location [classpath:/spring/rcr-service-appengine.xml]
Offending resource: class path resource [spring/service/appengine-
service-config.xml]; nested exception is
org.springframework.beans.factory.BeanDefinitionStoreException:
IOException parsing XML document from class path resource [spring/rcr-
service-appengine.xml]; nested exception is
java.io.FileNotFoundException: class path resource [spring/rcr-service-
appengine.xml] cannot be opened because it does not exist


I don't know how to debug or workaround this problem, cause it works
on the local appengine installation.
Am I missed something with regarding to security configuration or
whatever that prevents IO subsystem to load file?

My appengine-web.xml looks as follows (nothing extraordinary):



http://appengine.google.com/ns/1.0";
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-
instance"
   xsi:schemaLocation="http://appengine.google.com/ns/
1.0 
http://googleappengine.googlecode.com/svn/branches/1.2.1/java/docs/appengine-web.xsd";>
rr1234
test2



true


Please, help!

[google-appengine] Receiving mail at appspotmail.com. Message size limits, address filtering, spam protection?

[J C]

If I configure my app to respond to mail, is there any way to prevent a 
malicious user from spamming that address to drive up my incoming bandwidth 
and cpu costs?  Also, is there a message size limit when sending to the app?

Thanks!

[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: Task queue operation while datastore is in readonly mode.

Another thing to remember is that a put coming from the task queue may
overwrite a put that got done after the datastore came back to life
but before the task queue did the put. See this post for more:

[google-appengine] Re: Interested in giving us your thoughts on App Engine?

[J]

Presumably most of the services offered here would be optional to
buy?

Document Search and SSL were two features on the survey and /some/ of
the proposed prices were quite reasonable. My company currently offers
SSL for GAE (until Google comes up with theirs) and our prices are in
the middle of the range suggested in the survey. Seeing those
suggested prices wasn't particularly an OMG moment. Frankly, I can't
wait till Google comes up with the service.

The consulting and issue resolution services are another matter. Some
of us make our living by providing that service and I would like to
see Google do more to promote the services that the ecosystem provides
rather than try and take it over.

[google-appengine] Exploding Indexes

[J]

Under discussion of exploding indexes,
http://code.google.com/appengine/docs/python/datastore/queries.html#Big_Entities_and_Exploding_Indexes,
the documentation says "To accurately represent these values, the
index must store 12 property values".

Could someone please enumerate the 12 property values that must be
stored? It seems I'm missing something.

Thanks.

[google-appengine] Problem with my code!

[Kevin J]

I have this code:

-

class Group(db.Model):
  leader = db.UserProperty()
  description = db.StringProperty(multiline=False)
  name = db.StringProperty(multiline=False)

class Person(db.Model):
  email = db.UserProperty()
  groups = db.ListProperty(db.ReferenceProperty(Group))

class Message(db.Model):
  content = db.StringProperty(multiline=True)
  group = db.ReferenceProperty(Group)
  writer = db.ReferenceProperty(Person)
  date = db.DateTimeProperty(auto_now=True)



and this line is giving me an error:

  groups = db.ListProperty(db.ReferenceProperty(Group))

Here is my call stack:

What I'm trying to do is to create a list of groups that each person
belongs to. As you can see, it dislikes me having a list of Groups.

Does anyone know an alternative way to do this?

[google-appengine] Re: Is it possible to add Expiry headers to static files ?

[J]

Adding them is easy, as Robert indicated.

But be careful, not everything in the infrastructure respects them.
Perhaps I should have said, respects them too much. If you have a
static file header that is supposed to expire next Sunday, and update
the file before that time, the infrastructure is not required to serve
the latest version of the file since the expiry header has not expired
yet.

To get around this, you should implement some kind of a cache buster
(Google the term) unless the static files are truly static.

[google-appengine] Re: Let's defend GAE!

[J]

The acid test: would you recommend GAE to a friend?

I certainly would. GAE has helped me get my business off the ground
with an ROI that is unbeatable. Yes, it doesn't do everything. The
pieces it does not do can be done elsewhere (e.g., Amazon) and hooked
in. For example, for SSL, one can set up a proxy server on Amazon (see
http://wp.me/poqXr-5I). Using urlfetch, one can integrate pretty much
any service that is available on the web.

But if you want (or need) to fool around with your own OS, install
security patches, do your own backups, install your own software,
program in some of the unsupported programming languages or program
against a more familiar database, then GAE is not the right technology
for the job.

The best defense is not a rebuttal of negative things written about
App Engine. The best defense is an active and visible ecosystem. App
Engine does have that.

What could we do to improve it and publicize it more?

Johan, I had posted a solution to this problem a while ago:

In the past I've been ambivalent about providing it as a service
rather than just posting instructions for DIY folks. Lately warming up

Hi,

Hopefully someone can shed some light on this: all of a sudden, I
started receiving '409' errors. For example,

It has happened a couple of times already.

Thanks in advance.

[google-appengine] Re: Latency related follow up

[J]

kg,

I have been using GAE for a couple of years now and this is a highly
unusual situation. GAE has been a very successful product IMHO.

Whether recent events are a one-time situation or whether GAE has
become a victim of its own success is hard to say.

Speaking only for myself and my fledgling business, I intend to stick
with it.

As for what one can do, we do a fair amount of exception handling and
retry in the code. When testing, we go to the extent of injecting
random datastore errors and making sure the integrity of the data is
preserved. It gets expensive to do so, and we don't do as much as I
would like, but the investment has been worth it.

HTH.

[google-appengine] Re: Better way to implement many-to-many relationship

[J]

I'm a huge fan of Nick Johnson's method
http://blog.notdot.net/2009/9/Distributed-Transactions-on-App-Engine.

As originally written, it establishes links between two entities of
the same class but it is trivial to extend it to linking entities of
different classes. What I like about this model is that (a) it is
maximally sharded and minimizes resource contention and (b) the links
can be established atomically so the data store will maintain
consistency.

So for example to create a link between user and community, we define
a "Role" class (equivalent to Nick's Transfer class) that represents
that link.

As for storage costs, who cares?

[google-appengine] Re: SDK 1.3.6 released!

[J]

I switched to it yesterday but had to switch back to 1.3.5 due to an
issue with remote_api: Issue 178: ImportError: No module named
fancy_urllib.

Hopefully the issue will be fixed before 1.3.6 becomes mandatory?

[google-appengine] Re: AppStats missing for some urls

[j...@unusuallycool.com]

More info on this problem...

With my latest update I modified the servlet that wasn't getting
logged to use the memcache. Now, it only does its real work once every
10 minutes, and any calls in between it just sends the cached results.
The calls where it only uses the cache are showing up in appstats. The
calls that don't use the cache are missing.

The servlet in question does one special query to get the count of
entities of a certain kind, and then 2 normal queries for entities.

So it looks like it might have something to do with the special query?
(querying __Stat_Kind__ and getting the count property) does that make
appstats fail maybe?

[google-appengine] AppStats missing for some urls

[j...@unusuallycool.com]

I have AppStats set up on my app. It seems to be working correctly,
except that the stats for some of my urls are missing. I am using /*
for the url-pattern. Also in the admin console I am seeing the
"Appstats available..." log entry for these urls. But when I go to the
appstats viewer, they aren't there.

I also tried changing the url-pattern so that it explicitly gets only
the one url I'm interested in.  That has the same results, though. In
the admin console log, I see the "Appstats available" log message, but
no data in the appstats viewer for it.

I was using appstats before a while ago to debug a problem I had, and
that time I was using a different url-pattern. Could it possibly be
stuck with the old settings or something?

[google-appengine] Re: HTTPS on my own domain

[J]

Some of our experiences as well as hints for implementing an https
reverse proxy are documented here: http://wp.me/poqXr-5I. The
performance numbers are from measurements done this past weekend.
There is room for improvement and we hope to be able to report on them
in the future. Suggestions for improvements are welcome.

TL, thanks for the caution. Gave me the idea to access static files
using by using abc.appspot.com as the host URL instead of www.abc.com.
So those accesses still use https but not the reverse proxy.

[google-appengine] About Datastore

[George J. SUN]

Hi everyone,

I am a school and try to do a project via GAE. I learnt Datastore was
good at queries and reading.

But in my project, there are several robots on GAE getting and
processing some data from Internet and a PHP website(not on GAE
because of Chinese Internet fact) is for user to get the data.
The robots are mostly like spiders, but the data in Internet is not
updated very frequently. The website is not a search engine but just
like a summarizer.

Is Datastore or MySQL Okay for my project? Can I build my own
datastore in my own server? How can I use datastore via PHP?

Thank you!

[google-appengine] Re: HTTPS on my own domain

[J]

I didn't. Too afraid of cookie hijacking.

See http://en.wikipedia.org/wiki/HTTP_cookie#Cookie_hijacking. To
quote, "However a large number of websites, although using encrypted
https communication for user authentication (i.e. the login page),
subsequently send session cookies and other data over ordinary,
unencrypted http connections for performance reasons. Attackers can
therefore easily intercept the cookies of other users and impersonate
them on the relevant websites or use them in a cookiemonster attack."

We don't use any cookies until the user logs in and once they log in,
we stay on https for all traffic. Hopefully we don't run into
performance problems. While we consider the http channel and the https
channel to be completely separate, the common elements are the App
Engine (and the browser). We'd probably do the sharing in the
application code on App Engine if we get backed into a corner for
performance reasons.

Perhaps someone else on this list has a suggestion?

I tried it last year using Squid on EC2 as a proof of concept. It
worked well.

Now I'm in the process of putting it in production. Phil, I'd be happy
to compare notes next week or so if you wish.

[google-appengine] Re: Static files in newly deployed version not available in the apps domain. (Major problem) - issue raised

[J]

A couple of closing-out notes from our vantage point in Massachusetts.

First, even though the cache for one of our files was not supposed to
expire until June 5, it was serving the correct content as of late
June 3. Whether it was an ISP issue or a GFE issue, we will never
know.

Second, we have deployed the technique recommended by Donovan and hope
to never see this problem again.

Finally, a bouquet of virtual flowers for Ikai. Thanks for jumping on
the problem and helping us put a solution in place.

[google-appengine] Re: Static files in newly deployed version not available in the apps domain. (Major problem) - issue raised

[J]

Tim, what we ended up doing was a bit different. We have qa.abc.com
pointing to xyz-qa.appspot.com.

We did not change file names as was recommended -- that would be a
pain in the rear to manage. But we took advantage of the fact that xyz-
qa.appspot.com delivers content correctly. We changed references to /
scripts/pqr.js to http://xyz-qa/appspot.com/scripts/pqr.js.

It was faster to put in place and it buys us some time until we can
come up with something better.

Hope that helps.

Sorry for the delay, Ikai. I had to make a pervasive change in our
code base to put in cache-busting snippet.

Our app.yaml is below.

You will note two commented-out line for css. The 4d expiration was
removed yesterday in one of my attempts to get things to work. By that
time, the data was already in the cache, I guess!

Thanks, Ikai, for your help. It is much appreciated.

We'll use a cache buster for now.

That's interesting, Rafael. I wonder why it serves correctly for you.

They are still different from my PoV.

The bad side headers:
Etag"74EQOA"

The good side headers:

Short of using a cache-buster, is there a setting I can use on GAE or
in my app.yaml file?

[J]

To reproduce the problem, go to 
http://qa.connectscholar.com/stylesheets/caSkin.css
and also to http://charityaxis-qa.appspot.com/stylesheets/caSkin.css.
Both URLs point to the same file but one returns the old content and
appspot.com returns the new content.

Thanks, Tim, for letting me know I'm not going insane.

To the Google guys, this problem seems to have started yesterday
afternoon (1:30-ish PM, EDT) in case it helps you track down the
cause.

[google-appengine] Re: WARNING appengine_rpc.py:399 ssl module not found.

[J]

You are right, Matthew. It does not block. Still, the message is there
for a reason and uploading without SSL increases the exposure. While
my site is in QA, I'm OK just putting up with the warning. I'd need to
tighten up my procedures before going live. Hopefully by then someone
will have posted an MSI.

One could argue that taking an MSI from someone you don't really know
is as risky as not using SSL at all, because they could have modified
the code before building the executable. That's a valid argument. I
wish Google did it and placed it on the App Engine downloads page :-).

Thanks.

[J]

I am having this problem also. Found this thread in Google Groups:
http://groups.google.com/group/google-appengine/browse_thread/thread/9eb30d64423a37ea.

The module requires Visual Studio to build and install. To have to
install Visual Studio just for this seems a bit heavy. If some kind
soul out there could build an MSI and post it, it would be wonderful.

[google-appengine] A safer way to do dynamic property assignment?

[J]

I need to assign a value to a Model property but its name is not known
until runtime. For illustrative purposes, say

class Story(db.Model):
title = db.StringProperty()
body = db.TextProperty()

s = Story(title="The Three Little Pigs")

Since I wanted to decide on the property name at runtime, I wrote:
cmd = 's.%s = %s' % ('body', '"Once upon a time..."')
exec(cmd)

I shouldn't have to use exec. There has to be a better way of
assigning values to properties.

Any suggestions?

[google-appengine] Re: Allow/Deny IP Address

[J]

May I revise that "perfect for our needs" remark?

We are creating a service focused on US education and thus will not be
useful to anyone outside the US. We want people in the US to be able
to register for free. But since non-US folks wouldn't get any benefit
from the service, I'd just as soon not even let them reach my web site
-- why add to my server load?

It was perfect until I realized that to blacklist every country except
the US would take about 100,000 entries, a lot more than the 100-entry
limit of the dos.yaml file. I guess I will need to do that
verification inside my application.

Any other ideas?

[google-appengine] Allow/Deny IP Address

[J]

I am looking to restrict my web site and deny access from a set of IP
addresses, much like the Apache mod_access module does.

Would have expected to be able to specify it in app.yaml somehow (GAE/
Python). Any suggestions welcome.

[google-appengine] Re: Python and Java in the same app instance

Thanks, Jeff. I was afraid of that.

I like option #2 better. We use a lot of the python/GAE-related
features (templates, zipimport, appstat), and it's best not to mess
with moving it over to a jython-based implementation.

[google-appengine] Python and Java in the same app instance

[J]

We have a python application running on AppEngine and now have an
additional requirement to be able to call a Java library (iText for
now, possibly others in the future). Note that the Java code does not
need to service URLs, thus no need for appengine-web.xml. It just
needs to be callable from python code.

If someone could point me to resources about how this might be
accomplished, I would appreciate it.

[google-appengine] Bulletproofing for when Model.put() fails

[J]

Hi Everyone,

Background: Recommended practice for dealing with the Data Store is to
be prepared for the occasional failure. Within a transaction, when in
test mode, I simulate a transaction failure by randomly raising the
Rollback exception. This practice allows us to validate the exception
paths of the code when in test mode.

Now the question: when in test mode, is there a way to cause Model.put
() to raise an exception so we could test for this? Something should
be possible with hooks but if there is an existing best practice
around this, I would love to use it and/or build on it.

Thanks.

J Singh

[google-appengine] Model.get_or_insert

I hope there is something obvious I am missing but a call to
get_or_insert() fails in the sandbox (using eclipse on a Windows

The offending line is:
pe = PersonEmail.get_or_insert(email)

Class PersonEmail is derived from db.Model.

The error message says:

KeyError: 

I have never gotten transactions code to run in the sandbox so
wondering if there is some configuration that is needed. If someone
could point me to the right FAQ, I would appreciate it.

Thanks in advance.

[google-appengine] Flash and app engine

[j to the oh no]

Hi all.
I have what i think should be a straightforward question, but am
struggling to find a clear answer on the web. I would very much like
to begin using app engine to develop some web applications. However,
my apps require flash in some places and the flash apps need to be
able to interact with user data on the server. Will app engine support
this? thanks for any help.

[google-appengine] Re: Downloading pdf

[J]

Acrobat comes back and says "The file is damaged and could not be
repaired". If I skip the security checking and serve the file through
a self.redirect('downloads/filename.pdf'') Acrobat has no
problem with it, that is how I conclude that the file itself is OK but
the encoding is screwing things up.

There has been another recent thread regarding downloading files where
the core issue was IE. I have tested this in Firefox and Chrome so
pretty sure it is not a browser issue.

[google-appengine] Downloading pdf

[J]

I can't get GAE to send a file in pdf format. The code needs to verify
if the user has permissions and if so, send the file.

I thought perhaps encoding was the issue but base64 encoding the
content and declaring transfer encoding to be base64 doesn't work
either.


# Permission validation succeeded

self.response.headers['Content-Type'] = 'application/pdf'
self.response.headers['Content-Transfer-Encoding'] = 'binary'
self.response.headers['Content-disposition'] = 'attachment;
filename="filename.pdf"'
path = os.path.join(os.path.dirname(__file__), 'downloads/
filename.pdf')
infile = open(path,"r")
inbuff = infile.read()
self.response.out.write(inbuff)

[google-appengine] Different behavior static_dir dev vs live

[j...@q42.nl]

I've found a difference in the behavior of static_dir directives in
app.yaml.

My app.yaml:
handlers:
- url: /js/y.js
  script: js_templ.py
- url: /js
  static_dir: js

All goes well in dev server, because the devserver uses the js
directory.

On the live server all statics are handled differently, so the live
server scans the app.yaml and it matches all the files against the
static_dir declarations. On the live server the file js_templ.py is
interpreted as a static file, because the static_dir: js matches it.

I think the development server should work exactly like the live
server on this point. The difference is only noticed on the live
server so it's hard to find it and the warnings aren't clear.

[google-appengine] Slow response static javascript files on development server

[j...@q42.nl]

I have about 10 javascript/css files which are included in my html
pages, but it takes 1+ second to load each file on the development
server. This is highly anoying. Why isn't my static_dir handler using
Last-Modified/If-Modified-Since?
- url: /js
  static_dir: js
- url: /css
  static_dir: css

I've tried to set a expiration on the handlers as well as a
default_expiration.

These are the headers when I have expiration set:
Server  Development/1.0
DateFri, 04 Sep 2009 10:41:13 GMT
Content-Typeapplication/x-javascript
Expires Fri, 04 Sep 2009 11:41:13 GMT
Cache-Control   public, max-age=3600
Content-Length  100240

These are when expiration isn't set:
Server  Development/1.0
DateFri, 04 Sep 2009 10:41:18 GMT
Content-Typetext/css
Cache-Control   no-cache
Expires Fri, 01 Jan 1990 00:00:00 GMT

[google-appengine] Anyone using fiddler?

[j...@q42.nl]

I wanted to use fiddler on my local app engine development server. But
I get an error from fiddler:

[Fiddler] Connection to localhost failed.
Exception Text: No connection could be made because the target machine
actively refused it ::1:8080 (I'm working on vista, thats why the ipv6
address is show i guess)

I tried the usual fiddler workarounds (adding a dot, using machine
name), but that didn't work, still actively refusing

I need to somehow make the devserver listen to my machine name..

[google-appengine] static files not served with 304 but with 200 always

[j...@q42.nl]

I've got a bunch of static javascript files that are served with
status code 200 every time I refresh a page.

app.yaml:
handlers:
- url: /js
  static_dir: js

I've tried to set a global:
default_expiration: 1h

I couldn't find any discussion about expire or status code 304 in both

some tags that might help other to find this:

Sorry, I was referring to the $0.01/hr that Amazon charges for
reserving an IP address, thinking that a the proxy server was
essentially serving the same function.

[google-appengine] Re: https support

[J]

I have an idea, throwing it out to this group to see if it is sound.

What if there were a service in the cloud that served as an https
proxy? https://www.abc.com would resolve to this service and its sole
job would be to be a proxy for https://abc.appspot.com. Well, there is
the performance problem of the extra hop, and the trust problem of
whether we trust this service to not look at messages as it terminates
the SSL certs at either end.

Are there any other problems that anyone can see? It might be a nice
short-term solution until Google comes up with their solution.
Amazon's $0.01/hr translates to $7.20 per month. What if this service
were priced similarly? How many folks would buy it? Does such a
service already exist?

[google-appengine] renaming / destroying an appengine ?

[j...@red91.com]

hi, i know it's pretty impossible to delete an appengine app once
you've created one, but is there any way to rename it (the application
identifier) ?

also is there any way to change the Authenticiation Options after you
create it ?

Appreciate any pointers on this.


John.

[google-appengine] https support

[J Singh]

For an appengine-based site, https://abc.appspot.com is currently supported
but https://www.abc.com can not be supported. I know there is a technical
hurdle to cross but didn't know if any techniques had been proposed for
being able to use www.abc.com with SSL connections?

Thanks.

[google-appengine] Consuming OAuth requests in app engine

[j...@q42.nl]

Hi all,

I'm creating an opensocial widget on hyves.nl (a dutch social
networking site). I'm calling a makeRequest with
RequestParamters.AUTHORIZATION set to SIGNED. The GET call is enriched
with several query string parameters like:
* opensocial_owner_id
* opensocial_viewer_id
* opensocial_app_id
* oauth_consumer_key
* oauth_token (empty)
* xoauth_signature_publickey
* oauth_signature_method
* oauth_nonce
* oauth_timestamp
* oauth_signature

How do I verify that this request is coming from the hyves.nl
opensocial container?
I've found that GData does some oauth stuff, but that Api needs to
fetch an oauth token, while I just want to verify that the SIGNED
request is indeed coming from the container...

Anyone any pointers to the right direction?

That sounds promising. I very familiar with Java, but have just
started playing with javascript recently.

So basically you are suggesting that the client-side script would
loop, calling my service that would return with the GAE's 30 second
limit?
And, within that loop I could also update the client's page? That
would be great.

I'll see what I can figure out, thanks!

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

[J Keller]

Thank you Scott - that redirect trick worked great.

After processing a subset of the data, I simply redirect back to my
service.  Each time it caches more of the data, until the job is
complete.  Sometimes this can cause the browser to give up and report
an 'infinite redirect loop', but it usually works fine.  And even when
the it does give up, if the user tries again it usually finishes the
process fine.

Thanks again!
