[google-appengine] Re: Google app engine django helper, manage.py update, and (1,0,'final')

The currently released version of the helper (r52) supports Django 0.96 
and the early Django 1.0 alpha versions.

Support for Django 1.0 final is present in the HEAD (r60) of the helper.

I'd like to add support for loading Django 1.0 from a zipfile via the 
zipimport functionality in version 1.1.3 of the SDK before making a new 
release of the helper with Django 1.0 support.

In the meantime you should be able to use the helper and Django 1.0 
together by checking out the helper directly from svn.

[google-appengine] Re: how can I upload files bigger than 4MB use django and gae

Hi,

If you combine these you can work around the upload limitation:

* Amazon S3

* S3 POST: 
http://developer.amazonwebservices.com/connect/entry.jspa?externalID=1434&ref=featured

* boto: http://code.google.com/p/boto/

* appenginepatch: http://code.google.com/p/app-engine-patch/

Your users will have to upload files to S3 via POST. IOW, the files
have to go directly to S3 instead of passing the App Engine servers.
The App Engine server only generates a policy which authorizes the
upload. AFAIK, boto already has a simple function for generating that
policy. Just look at
boto.s3.S3Connection.build_post_form_args()

Hm, ok.  Well, yes that could be it ;)  I was kind of  hoping he had
found some kind of workaround that made it possible to parse an XML
string without having to write anything to the local filesystem.  And
it -is- parseString that barfs, there is no need for it to write
anything to the filesystem even if the implementation obviusly does
so.

[rmz]

This code gives  the same error as the examples above when I try it.
Did you use more code than what is available in 
http://cibass.de/gae/AtomHandler.txt
?

What fails is actually an assignment within the constructor of the
URLopener class.
The constructor refers to os.unlink, which fails, but I don't know if
the unlink reference
is actually used anywhere, so if the lookup could somehow be made
lazy, the code might work.

/me is confused (but muddling along ;)

[google-appengine] Re: App.Yaml seems to be malfunctioning

[Wooble]

The 404 errors are for favicon.ico.  /newuser is a 405 error, which
means there's something wrong with the handler in NewUser.py.

Does your CreateNewUserPage handler have a get() method defined?

That is really confusing, because the AtomHandler works great on
http://plgoals.appspot.com (top right and do not be scarred about the
rest ;) ).
I'am instantiate the class as follows:


from AtomHandler import AtomHandler

atom = AtomHandler("http://www.heise.de/newsticker/heise-atom.xml";)

for news in atom:
self.response.out.write('' +
atom.news['title'] + '')


I know about the issue with os.unlink, but if xml.sax.parseString is
used the os.unlink function is not called.
It is barred that this problem is related to the python version,
because everyone who use GAE should have the same python version.

I uploaded all importent files to run AtomHandler like on plgoals:
* The AtomHandler class: http://cibass.de/gae/AtomHandler.py.txt
* The MainPage class which inherits
google.appengine.ext.webapp.RequestHandler: http://cibass.de/gae/MainPage.py.txt
* The .html template used by MainPage: 
http://cibass.de/gae/MainPage.html.txt

Hope it helps,

acm.

Originally in Django, locale could be set via session. But GAE cannot
work with session in Django. So I tried to set
settings.LANGUAGE_CODE='zh-cn' directly to make i18n works
dynamically. It works.

Maybe there are some other ways.

I never tried Django 1.0. All above is based on GAE built-in Django 0.96.1.

this is my client side code (pure python). You'll see that

After several months of reliable use, suddenly the appcfg.py stopped

my app version from 1 to 2.  It started working again after that.

I've committed a change to the Google Appengine Helper for Django

The default path for the datastore is in /tmp which on some 
distributions is cleared on reboot. You can run dev_appserver.py 
manually and specify the --datastore_path and --history_path options to 
put it somewhere else.

[google-appengine] Re: local log file

[Marzia Niccolai]

Hi Joseph,

Currently, dev_appserver logs are printed to the terminal.  It only prints
info level logging, so to view logs in development, you will need to log at
this level.

I presume that you're using Django 1.0?

Anyway, this looks to be Django 1.0 related breakage to me. I've 
committed a fix in r62 that makes the login/logout URL template tags 
available to all templates by default.

[google-appengine] Re: maximum reference dataset size without timeout

[Marzia Niccolai]

Hi,

Adding an index here should have no effect.  The reference property stores
the key for the referenced value, and retrieving it is a simple get
operation - the quickest there is.

I doubt that the timeout is occurring for just one get - if you are
operating over a large enough set of data, it is possible this is where the
error is occurring, and you should try to reduce the amount of data fetched.
With out seeing any code, it's difficult to provide more specific advice on
how you might eliminate the timeout message.

[google-appengine] Re: Delete all data for a kind

[Marzia Niccolai]

Hi,

Currently there is no quick solution for deleting all entities of a specific
kind.  The only way this can be achieved is to write a handler that chunks
the data in to manageable sizes, and then deletes the data over a series of
requests.

If this is something you'd like to see, please star the issue for in the
issue tracker.

Hi,

Assuming you've stored the user object and login date in your datastore, the

# Assume user is logged in
user = users.get_current_user()

last_login = Login.filter('user =', user).order('-login_time').get()

[google-appengine] Re: Which versions of Python work?

[Marzia Niccolai]

Hi,

Currently App Engine runs Python 2.5.  It is possible to run the App Engine
SDK under other versions of Python (such as 2.4), though there are no
guarantees that it will be 100% compatible.

All applications are currently written to run with Python 2.5, and it's
unlikely we would introduce any changes for that would break these apps.

If you are interested in Python 3K support, you should file that feature in
the issue tracker.

[google-appengine] How to create SOAP server in GAE

[Hasanat Kazmi]

Hello folks,
I am facing a problem. I want to create SOAP web services using GAE. I want
to create server (so that others can utilize it) not client (I dont want to
utilize other SOAPes)
The problem is I have looked into few solutions on the internet specially
SOAPpy but when the create a SOAP server, they also create Web server to
handle it, secondly it is highly feasible that it won't work on GAE.
Anyone having an idea how to do it

Hi,

If you could provide some more information, that would be helpful:

What version of the SDK are you currently running 1.1.3?
What version of Mac OS are you running?
Are you using the Mac Python install, or a different Python installation
when running the SDK?

Thanks,

[google-appengine] Re: Urlfetch works fine at localhost but errors out after uploading

[Marzia Niccolai]

Hi,

This error indicates that the URLFetch request took too long to complete (we
allow around 5 seconds for a URLFetch request to complete).

Since the performance characteristics of the dev_appserver are not exactly
inline with App Engine, we do not enforce the deadlines on the SDK as we do
in production, which is why these errors only occurred on upload.

[google-appengine] Re: How to solve this problem(just like" in" in sql)

[Marzia Niccolai]

Hi,

For this query you do not need to use an 'IN' query.  The correct query is:

db.GqlQuery("SELECT * FROM PDM_InitReportEntity WHERE Users =
:1",curentuser)

From
http://code.google.com/appengine/docs/datastore/typesandpropertyclasses.html#ListProperty:

"In a query, comparing a list property to a value performs the test against
the list members: list_property = value tests if the value appears anywhere
in the list, list_property < value tests if any of the members of the list
are less than the given value, and so forth."

[google-appengine] Re: Confusions on transactions and concurrent writes to entity groups

[Jeff S]

Hi David,

Even if a put request to the datastore is not run in a transaction,
the operation is automatically retried. Contention is not unique to
transactions. The benefit of using transactions, is that if one write
in the transaction times out (due to too much contention or some other
issue) the other parts of the transaction will not be applied. For
more details see: 
http://code.google.com/appengine/docs/datastore/transactions.html#Using_Transactions

Happy coding,

Jeff

To further clarify. All writes are transactional. Details on how the
transactions work can be found in ryan's presentation from Google I/O:
http://snarfed.org/space/datastore_talk.html The section on
transactions specifically begins at slide 49. You can also watch the
video here:

[google-appengine] Re: Strange expiration date (now + 1 day)

[Marzia Niccolai]

Hi Sylvain,

My simple 'Hello World' with the Cache-Control set seems to always set this
header as expected, so if you could point me to a URL in your application
that you have noticed this behavior, this will help us pinpoint where this
might be occurring.

Also, do you set any expirations explicitly in your app.yaml file?

I am looking in to the report of the same issue on the admin console.

Thanks,
Marzia

[google-appengine] Re: Strange expiration date (now + 1 day)

[Sylvain]

Hi,

Yes, i thought is was an issue with the app.yaml. So, i've removed it
('default_expiration'.).
But this bug continues.

One important thing : it is random. And to raise it, it was sometimes
hard/long.

If the Dashboad is a GAE app (like ours), it has the bug too.

Check these images : I've reproduced this bug for the Dashboard.

http://testgapp.appspot.com/nppEvndmbnDzp7vgeVQoc3ygG2okoD

For my app, I've removed this bug by adding :

[google-appengine] Re: Urlfetch works fine at localhost but errors out after uploading

[Downtown]

WOW! Please provide a link in your documentation where this is
discussed. You need to put this limitation in big red letters
someplace. Now I will need to recode major pieces of my application.

Please provide a few recommendations.  I really need assistance.  My
deadline is almost here and I was not anticipating this extra work:

1) Any work around on this issue?  Can I run a procedure off line
looping urlfetch until I get what I need?
2) I have noticed that if you request a feed (using urlfetch) several
times in a row it will not timeout.  It is like Google App Engine
eventually caches the feed so when you request it a third or forth
time it work.  Is this true?
3) Any issue requesting a feed direct to the client and have the
client POST the feed to the server.  I did not want to go down this
road due to security issues of POSTing a large feed to GAE from a
client.  I may not have a choice.

Thanks

I added the following in my test setup:

os.environ['APPLICATION_ID'] = APP_ID

... along with the other environment variables that are locally set
(AUTH_DOMAIN and USER_EMAIL). This was done after the call to create
my DataStoreFileStub instance. No other change was necessary.

Hope that helps!

http://code.google.com/appengine/docs/urlfetch/overview.html

"Since your application must respond to the user's request within
several seconds, a URL fetch action to a slow remote server may cause
your application to return a server error to the user. There is
currently no way to specify a time limit to the URL fetch action. One
way to control the user experience of a slow remote server is to use
browser JavaScript to call a separate handler on your application that
performs the action that requires URL fetching, then report the error
to the user if the handler fails."

Note that an urlfetch which is taking long is apparently considered a
high CPU operation even if it's not CPU-bound, so if you repeat the
request several times and you do it frequently then your app may be
banned temporarily due to overshooting its high-CPU quota.

Why a long IO operation is counted as a high CPU operation is beyond
me, but you can see the heaps of CPU warnings in your logs if you do
such operations.

[google-appengine] Admin Users

[Sam G]

GAE Group,

Quick question... I've got a Google App Engine app setup for
authentication with a GAFYD account. I had thought that the
"is_current_user_admin()" method returns True if the user has admin
privs for the GA domain.

I guess not - it isn't working for my Google Apps Admin. Upon closer
review of the Users API documentation, I read that "You can manage
which users have administrative status using the Administration
Console.".

Where do I do this?

I have already added the user in question as a developer of the
application. Is there something I'm missing?

[google-appengine] Re: Urlfetch works fine at localhost but errors out after uploading

[Downtown]

Thanks for pointing this out but you need to clarify in red letters
that the Dev environment does not behave the same as Prod or there is
an imposed 5 second timeout.

>"Since your application must respond to the user's request within
> several seconds, a URL fetch action to a slow remote server may cause
> your application to return a server error to the user.

I ready this weeks ago.  I just assumed in the Dev environment that my
"slow remote server" was fine.  I didn't get any timeouts so why would
i think otherwise!  Also, please consider adding additional
documentation that a localhost development environment may be
insufficient to adequately test and certify an application.

Please take this as positive feedback.  I just want to help the next
developer and clarify this issue.

Any thoughts or suggestions from the questions I pointed out before?

Thanks!

That url is to the Google Chart API. For a given set of URL params the
chart should never change so it doesnt matter what the expires is. If
the chart needs updating the URL will change which will defeat the
cache. For a chart it only matters what the parent pages caching is
like.

[google-appengine] Re: User Authentication

[Sam G]

My3,

Yes, you can integrate with your existing (and future) Google Apps
user accounts.

When setting up an application (go to appengine.google.com, sign in,
select "Create an Application"), click on the link at the bottom of
the page labeled "Edit", under "Open to all Google Accounts users
(default)". Select the radio button for "Restricted to the following
Google Apps domain:", and enter your domain name in the box.

Push save, and it will now use your existing user accounts and
passwords.

[google-appengine] Re: Strange expiration date (now + 1 day)

[Sylvain]

Yes, it's true but the parent page gets a now + 30 minutes :
http://testgapp.appspot.com/nppEvndmbnDzp7vgeVQoc3ygG2okoD

And it's random too. Most of the time, i've got a "no cache"
expiration date.

EDIT :

I've just tested it again and now i've got a now + 1 day ?

So if I click the "dashboard" link : it never refreshes during 1 day.
It was the exact same thing with my app.

[google-appengine] Re: Problem Setting Date property to None

[jtbrne]

There has to be a better way, but I can't figure it out and this isn't
very important to my problem.  The problem seems to be that the django
form won't actually set a dbmodel DateProperty to None.  There does
not appear to be an issue with the StringProperty.

entity = data.save(commit=False)

for property in dbmodel.properties():
 if self.request.POST[property]=="":
  setattr(dbmodel, property, None)

entity.put()

[google-appengine] Dashboard - Logs - How to clear them? - What is the Date-Time reference?

[djidjadji]

I have 2 questions about the Dashboard Logs window.

What is the reference of the Data-Time used in the log messages?
It's not UTC (as used in the Datastore). Is it PST? And how much does
this time differ from UTC?

How do I clear the log messages?
Every time I look at the log window I see a lot of (quota) messages.
After careful looking at the date-time I find there are NO new ones.
Is it possible to purge the log messages you know or that I have
downloaded with appcfg.py?

[google-appengine] Re: NeedIndexError, but index is in index.yaml file

[djidjadji]

Hi Marzia,

Yes Alexander is correct.

I have read the issue and have exact the same problem.
In my index.yaml file there is also the following entry as the first
index, placed by devappserver.py.
===
- kind: FooA
 ancestor: yes
===
This is because in some cases I want all the FooA objects that have a
certain parent.
But sometimes I just need a selection of them, and what I heard from a
Google IO talk was
"If you can: let the Datastore work for you" that is why I added the
filter() call.
But to work around the bug I have done the work myself and implemented
the filter
with python if-statement. At the moment the parent does not have a lot
of FooA childs but that might not be the case in the future ( and then
I get hit by the CPU quota ;-)

[google-appengine] memcache: is it distributed or local?

[djidjadji]

To speed up the response for most queries I use memchache to store
part of the generated html.
When the objects change that are used for this memcache entry I call
memcache.delete(key) then
I redirect myself to the page that will generate the memcache content
for this key.

What I see is that sometimes the new page contains the modifications,
memcache(key) is updated.
In the other cases I see the old content. Then I wait a while and do a
second reload
and then I see the new content. I don't think it is a browser cache
issue because there are cases
where the updated content is show when I redirect.
If the redirect is serviced by the same host I can assume the memcache
item is deleted.
But if the redirect request is serviced by another host or another
datacenter is the item then also deleted?

The manual and a few post in this group memtion that mecache inc() and
dec() an integer value atomically in the memcache.
This would suggest that ALL instances of my application see the same
memcache items.

My question?

Is there one (1) memcache as observed by the programmer?
Does it take time to distribute the delete (or inc or dec) operation
across the datacenters?
Or is the memcache separate for every host or every datacenter?

All the examples that use mecache that I I have seen use it for
keeping score of a total with a timeout of around 60 min.
Not a problem if it is not the exact number (of people online, of
messages posted today...)
I have a timeout value of around 3600 (60min), large time between mutations.

Am I missing something? I believe I've used the -d (--debug) parameter to
dev_appserver to get debug-level logs printed on the terminal.

Or are we talking about two different things?

[google-appengine] Re: Dashboard - Logs - How to clear them? - What is the Date-Time reference?

[Marzia Niccolai]

Hi,

To answer the first question, the logs are currently displayed in PST, which
is currently -7:00 from GMT.

As for the second question, currently there is no way to clear log
messages.  However, if you upload a new version of your application, that
version's logs will be stored on new page with messages relating only to
that version.

[google-appengine] Re: How to create SOAP server in GAE

[Greg]

You are right that appengine does the webserving for you. To provide a
SOAP service, you simply need to...

- Decode the XML contained in the request
- Do something with it
- Encode the response in XML.

I'll leave it to you to google for python XML modules.

Cheers!
Greg.

[google-appengine] Re: NeedIndexError, but index is in index.yaml file

[Alexander Kojevnikov]

Marzia,

Can we expect this to be fixed any time soon? This bug is very
annoying. As mentioned by djidjadji, workarounds can be very resource-
intensive. Usage of indices (vs manual filtering) is encouraged in the
docs, but this bug makes it impossible with a very obscure error
message.

Thanks!
Alex

[google-appengine] Comment system - preview, edit?

[David Underhill]

The system for commenting on an application would be a bit better if
one could preview the post, and perhaps edit it if needed.  Also, it
is easy to miss the stars portion of the comment and rate the
application "0 stars" on accident.

Just some thoughts!

[google-appengine] Having trouble uploading application.

[[EMAIL PROTECTED]]

I'm sorry, this is going to sound very beginner-ish (because I am one
obviously). I've made my application and I'm trying to upload it but I
keep running into problems. I'm using Ubuntu, and I go into the
terminal and type  /home/*username*/Documents/google_appengine/
appcfg.py update  and get the
output bash: syntax error near unexpected token `newline'. Am I doing
something totally obvious wrong?

Do the logs count towards the storage quota?

[google-appengine] Re: User Authentication

[My3]

Sam,

Yes i am currently using it. But i want to host an application
elsewhere which has to be used only by these Google Apps users.

So for that can i use Google App engine to forward the authentication.
Or else can i use any other authentication.

[google-appengine] Re: High Amount CPU Quota should be removed

[Ethan Post]

Agree 100%. All I am doing is posting 10-20K every now and then, say every
15 minutes and I get warnings with every post, only 1 or 2 puts. I have
tested my app for a few days and all my daily quotas stay at near 0%.

Agreed. The problem at Google is very simple and has two components.
First, the engineers run the show and there is no rational voice at
Google to point out to them when they do something that does not meet
a real world demand (they make something stupid). And the second
component is they still have a lot of money to blow so they can get
away making things that do not meet market demand (writing stuff that
does not work and is stupid).

These two problems are endemic at Google. And the only thing to cure
it is some red ink on the books.

An example of the problem as lined out above that comes to mind is
Google's Carrier Calculated Shipping API in Google Checkout which was
released exactly one year ago. Carrier Calculated Shipping as
described here:

http://googlecheckoutapi.blogspot.com/2007/09/carrier-calculated-shipping-is-here.html

" is to provide buyers with shipping rates for the major shipping
carriers." This allows merchants to provide shipping rates to buyers
when they provide information about the shipments for Google Checkout
Transactions.

It does provide rates. Rates that are 30% or more off the actual real
rates from UPS, FedEx or USPS.

It seems that the Google Engineers have designed an Algorithm to
compute the rates instead of using the published web services from the
carriers which give accurate results. I am sure the Algorithm required
many hours of time from the best of Google Engineers. And I am sure
the engineers are sure they have coded the best shipping cost
predictive algorithm known to man, with only a +/- 30% margin of
error!

Don't question the fact that a merchant may lose $ on every
transaction with low shipping costs or scare away customers with
overly high shipping cost. The Google Engineers are smarter than you!
They have designed the best Algorithm in the world to compute shipping
costs. +/- 30% is acceptable to them and no one in the world could do
better.

It is the same with Google App Engine. The Google engineers have
designed the ultimate computing platform. Who are we to question the
fact that it can not repeatedly return a reasonably sized result set
without displaying an "Over Quote" error page. You just do not know
how to use it!

There is a demand for free/low cost reliable scalable cloud computing
services. Even those that run only python web frameworks.

There is not a demand for a cloud computing service that can not
repeatedly return a reasonably sized result set without undo amounts
of caching or other machinations to get it to happen. Nor is there a
demand for a checkout system that returns wildly inaccurate shipping
quotes!

I am sure the Engineers will all be very puzzled when they try to
charge for Google App Engine and no one is willing to pay. Just
remember that they are smarter than you and their solution is the
best. Even if you would never pay for it.
