Nope. There was no change to any files or configurations since several months

And I'm moving this question to stackoverflow.com.

[google-appengine] 404 Not Found problem on my Java GAE app

2012-05-23 Thread Cheolgoo Kang

Hi there,

I'm running a paid GAE app written in Java and it's id is clip-share, so 
the url is http://clip-share.appspot.com/.

I've run it for more than 10 months, and since 2 days ago, it starts not 
working with 404 not found error.

When I connect to http://clip-share.appspot.com/index.html, I fails with 
this message that there is no index.html file which really does exist.

Error: Not FoundThe requested URL /index.html was not found on this server.

I tried re-deploy this app for a few times, but it works with no problem 
just for a few minutes right after the deploy, but doesn't work after that.

And also searched for the 404 not found problem, I found this thread but 
there is no specific information about the cause and some way to solve it.

https://groups.google.com/d/topic/google-appengine/8liP4T-wbSo/discussion


So, what's happening? and how can I handle it?

[google-appengine] geographic expansion in plan or just price increase?

2011-09-05 Thread Minsu Kang

Have used gae for commercial purpose in South Korea. The latency is
about 0.5 second or 500ms and couldn't make it usable with various
image loading so that separate hosting for images was used.

Though there is a feature request on this issue, it seems that no
progress is being made at all.

Today, I received an email regarding new pricing table and it is about
10x increase for my company web service and AWS is soon to be
available in the region (hopefully this month). Now I need to decide
whether to consider other options or not.

Could someone in google help me with any tentative schedule of
deploying GAE in South Korea or at least in the region?

Thanks.

old_date = datetime.datetime(2009,10,1)
old_updates = SomeUpdate.all().filter(updated ,old_date).fetch(20)
db.delete(old_updates)

it costs me nearly 1982cpu_ms 1945api_cpu_ms every time. Is it normal?

 You might be able to save some time by using a keys_only query. See

 Hi Team,

 I'm making an app to implement following design:

 binary+text - browser - app engine(my app) - 3rd party server

 My problem is in the last step,the 3rd party server requires binary
 +text being posted as multipart form data.
 How can I simulate this with app engine?

 Any information would be appreciated.

Hi,

This may not work for your particular use case, but you can use an
equality filter in conjunction with the key filter, so instead of
something like:
suggestions = Suggestion.all().filter('__key__ =',
bookmark).order(__key__).fetch(PAGESIZE+1)
you could do:
suggestions = Suggestion.all().filter('title =',
VALUE).filter('__key__ =',
bookmark).order(__key__).fetch(PAGESIZE+1)

Which would at least allow users to query on a small subset of values
(those that specifically equal a property) and still allow paging on
the results.

[google-appengine] Re: Dynamically Choosing Which Properties to Write to the Datastore

2009-01-24 Thread kang

You can get the form data through
self.request.get(name)

and give the object proper property.

for example, in the html

form action=/submit method=post
input name=a
input name=b
input type=submit value=Post
/form

in the server side, you write,

class Submit(webapp.RequestHandler):
def post(self):
a = self.request.POST.get('a')
b = self.request.POST.get('b')
object = Object()
object.a=a
object.b=b
object.put()

 Has anyone tried to dynamically select which properties they want to
 write to an entity on appengine? For example:

 I have a web form with 5 fields, and any given user will fill out some
 subset of those fields. I POST only the fields with data to the server
 (e.g. Fields 1,2,4). On the server side, how do I elegantly write only
 properties 1,2, and 4? The Model class has a function that returns a
 dictionary of property names (Model.properties()), but how would I use
 it to select property names?

 In SQL, I would build an INSERT or UPDATE statement by matching the
 fields POSTed against the Model.properties() dictionary. I read trunk/
 google/appengine/ext/db/init.py which seemed to confirm that there is
 no way to refer to the properties as a group. Am I approaching this
 the wrong way? Anyone know of a workaround?

 correct. if you have both inequality filter(s) and sort order(s), the
 first sort order must be on the same property as the inequality filter
 (s). this is a fundamental datastore limitation, unfortunately, and
 one that we have no plans to remove any time soon.

  If your 'date' property really is a date, and not a date+time, you
  should be ok.

 actually, this limitation is unrelated to property type. (hopefully
 i'm just misunderstanding your point here...)

  Hello everyone,
 
  Some of you may have noticed the recent addition of a guru listing
  at the top of our main groups page. We've selected a few top
  contributors to the App Engine community to act as App Engine Gurus.
  Gurus will continue to post normally in the group, but are now
  officially noted for their excellent contributions. The gurus were
  selected based on their eagerness to participate in the App Engine
  community as a whole and their advanced knowledge of the API.
 
  The newly appointed Gurus are:
 
- Alexander Kojevnikov
- Bill Katz
 
  Google will continue posting normally alongside the gurus. Our primary
  focus is to help developers using the API, and the gurus will help
  with that focus by continuing to help provide knowledge and answers to
  those who ask. Remember that this list isn't fixed. Gurus who stop
  participating may be removed, and others who demonstrate the level of
  expertise and willingness to participate may be added.
 
  If anyone has any questions, feel free to reply, contact me directly,

 1. Sign up for Google Apps to register this domain
 2. Prove that you already own it

 I would like to use option #2, to merely prove I own the domain.

 Not sure how or where you do this, but my domain is already setup. I'm
 sure many others as well, got your Windows PDC, logins, intranet,
 everything said and done, Exchange in place, everyone using the
 domain... but you got some worthless webhost in BFE displaying your
 little external webpage.

 Okay in other terms: No need at all for Google Apps, just want to have
 the public side of the domain for the website point to a shiny new
 Google App Engine application.

 How do you do this? I'd assume the 'proof' would be in pointing
 current domain registrar www to Google's server for your app or
 something like that?

  just to clarify, for the purposes of the archives. in case there's
  confusion between the two get() methods: Model.get()/db.get() are
  generally the fastest, modulo the size of the entity. Query.count(1)
  will be in the same ballpark, usually a little slower, but faster if

 By index I mean whatever index you are using for pagination, an integer

 This should work to page searchable entities as well. Simply search for a

 this cant really be fixed. The application is not really doing a lot
 of processing by itself, but it has to do some busy waiting for (using
 sleep) the JavaScript app servers to reply, so that some of the
 requests might take a while.

 It'd be nice if the quota could be increased, since, by design, the
 app isn't really supposed to ever actually use a lot of CPU (because
 processing is done on the app servers)

  Hey,
 
  just wanted to let you guys know about a small project/experiment of
  mine that you might find interesting. I created a sort of application
  server that runs within Google Gears workers which have a pseudo
  persistent connection to an App Engine application. Clients can send
  http requests to the App Engine app which are then delegated to the
  application servers on clients running the Gears application. In a
  (twisted) way this also enables writing parts of App Engine
  applications in JavaScript.
 
  More info is here:

 I am about to take the GAE plunge (at least in the experimentation
 sense).
 I understand the current irritations and I am hopeful that these will
 be overcome in due course

 But I am very curious how far Google can take this thing...

 A key question on everyone's mind:

 Can we assume that GAE developers will eventually be able to produce
 GAE apps with similar complexity, reliability, scalability and
 performance ballparks as Gmail, subject of course to hosting fees?

 If the answer to that question is YES, then I am am convinced that
 GAE will eventually be able to host sophisticated financial
 applications that are not currently in the GAE sweetspot, e.g.
 accounts, payroll, etc

 Or would it be more realistic to assume that GAE developers will never
 really be able to leverage what Gmail's developers can leverage?

 Looking beyond the Gmail comparison, I see lots of problems with the
 GAE datastore for financial applications e.g. the absence of joins,
 aggregation, etc. I understand that these limitations are inherent to
 the BigTable paradigm, yet I already see posts by developers showing
 how these limitations can be overcome. Solutions tend to revolve
 around de-normalisation and other forms of data redundancy together
 with a sizable smattering of code trickery. All very, very botchy and
 alien to the GAE philosophy of removing much of the the tedium of web
 development.

 I am wondering if it will ever be possible to write an abstraction
 layer that will present the underlying GAE datastore as an SQL
 database albeit at a cost in terms of data efficiency, CPU cycles and
 bandwidth...or is this completely missing the point?

 Bear in mind that I am thinking a few years down the road.

 to user urlfetch, and I have succeeded except for the final step. I
 got the request token, I get the access token, but then, when I try to

 the problem is that with urlfetch you cannot control how the url is

 Any of you has got GAE+oAuth working ?

 Hi,

 I suspect that the Google App Engine (and cloud computing more

 usage of Linux among web developers.

 The solution of course is for Google to release a user-friendly and
 slick Google OS built on top of Linux that makes the web the main
 source of apps.

 But even that's not enough since many people (even web devs) play
 games on Windows... and linux cannot compete at all in that regard.
 One could argue that the shift towards game consoles is making Windows
 less important for games, but that will take time...

 Solution for your problem is simple. First you need to know that
 template 'language' is not so powerfull that you expect and from my

 You need to organize data in your class handler in python code before
 you render it with template. In python you can do it on many ways so
 that instead you have one image collection you could have collection
 of collection (max five images for you problem).

 In template file than you can have nested for loop.

 The source code of the SearchableModel is well documented and contains
 examples of how to use it:

 Also, google for SearchableModel, there are quite a few blog posts

 This is not true. Have a look at
 http://code.google.com/appengine/docs/gettingstarted/usingdatastore.html

 If you want to use part of the URL path as arguments to the handler
 you use groups in the
 webapp.WSGIApplication argument.
 If the URL has parameters (there is a '?' after the URL path) like
 www.a.com/?a=1b=2
 You use self.request.get('a') in the handler to get the value of parameter
 'a'

  I am new to Python and GAE. I just give you the way I solved the

  But I don't think your interpretation is correct. It's not a
  Request/parameters problem. It's a Get/parameter problem. Usually we can
 see
  url like /book?id=11. We use get method to visit that page to watch a
 book
  whose id is 11. You can not get any parameter by using request.get(id).
 
  So I use /book/11 and
  application = webapp.WSGIApplication(
 [(r'^/book/(?P(
  bookid)$d+)$', Book)],
  debug=True)
  to get the bookid, and give it to Book.Get(self, bookid) function.

Then there is a form on the same page (/stuff) which processes some
additional input ('morestuff') and supplies me with a few other
 pieces
of data via post. When I process this using a def post(self) in
 Stuff,
I use self.request.get('morestuff').
  
But can I also access the original 'favorites' in the post method? I
can't find any documentation about this but perhaps it's because
 it's
just obvious. I guess the question is does the self.request object
 get
cleared after get(self) finishes generating the page, or are the
original query params still available to me when I call
self.request.get in the subsequent post method (is the dictionary of
key value pairs in the request object replaced, or augmented by post
data?)

 One of the most frequently requested features for App Engine has been HTTPS
 serving capabilities.  Today we're excited to announce that App Engine now
 supports incoming HTTPS connections using a certificate valid for all
 appspot.com URLs.  Here's how it works:

 * app.yaml files now support a new handler attribute, called secure:

 - url: /accounts/.*
   script: admin.py
   login: admin
   *secure: always*

 *This attribute can be either always, optional, or never (default),
 and determines the behavior of the handler for HTTP and HTTPS requests.  See
 our documentation for more details:
 http://code.google.com/appengine/docs/configuringanapp.html#Secure_URLs

 * HTTPS requests have their own bandwidth quotas, but also count toward
 your total bandwidth quotas.  You can monitor these quotas on your
 dashboard.

 You may be wondering why we're only supporting appspot.com right now, and
 not arbitrary Google Apps domains.  This has to do with fundamental
 limitations in the SSL protocol (see:
 http://en.wikipedia.org/wiki/Https#Limitations).  We're currently
 investigating workarounds for this using e.g.
 http://en.wikipedia.org/wiki/Server_Name_IndicationSNI (
 http://en.wikipedia.org/wiki/Server_Name_Indication), which provides a
 viable solution for newer browsers--we'll keep you posted!

 This functionality is already available starting with the 1.1.5 SDK.

[google-appengine] Re: Getting 'UnicodeDecodeError'. Please help

2008-10-15 Thread Kang

It is because there are some illegal string in the string you want to 
process. So with decode(UTF-8,ignore), you can decode it without errors.

I think Dive into Python is a good  choice.

p.s.I am new to Python, too. And I am a Chinese, so I need to always 
deal with decode error problems. Because GAE dose not support Chinese well.

Nishu ??:
 Thanks, it worked. At least the application is not raising such errors
 any more. I am novice as far as Python is concerned so can you please
 give a short explanation for the solution you provided. With this code
 what I noticed is that the character which was creating problem was
 not included in the final result string. So I tried with the
 following

 a.decode('utf8','replace')

 This statement instead of removing the character replaced it with some
 other character. So please suggest which one should I use, the one
 with 'ignore' or the one with 'replace' and WHY? Can you also suggest
 me some good book for learning PYTHON?

 Thanks once again.

[google-appengine] Re: Modeling mutual references

2008-10-15 Thread kang

Maybe:

class Book(db.Model):
   title = db.StringProperty()
   first = db.ReferenceProperty(Page)

class Page(db.Model):
   text = db.TextProperty()
   next = db.SelfReferenceProperty()
   book = 
db.IntegerPropertyhttp://code.google.com/appengine/docs/datastore/typesandpropertyclasses.html#IntegerProperty
(BookID)

 Is it possible to have two models reference each other? I can't get
 this to work and haven't been able to find this limitation in the
 documentation. As a simple example, consider:

 class Book(db.Model):
title = db.StringProperty()
first = db.ReferenceProperty(Page)

 class Page(db.Model):
text = db.TextProperty()
next = db.SelfReferenceProperty()
book = db.ReferenceProperty(Book)

 which generates NameError: name 'Page' is not defined when
 processing the Book class definition. Is this really a limitation of
 the underlying data store or is it more related to how models are
 defined in Python?

 I'm guessing the solution is to record the 'first page in book'
 information as a separate class, for example:

 class FirstPage(db.Model):
book = db.ReferenceProperty(Book)
first = db.ReferenceProperty(Page)

 any pointers would be gratefully received, Adrian

[google-appengine] Re: Newbie question - Request params available to def post(self)

2008-10-15 Thread kang

I am new to Python and GAE. I just give you the way I solved the
GET/parameters problems:-)I think I need to read some example codes~

But I don't think your interpretation is correct. It's not a
Request/parameters problem. It's a Get/parameter problem. Usually we can see
url like /book?id=11. We use get method to visit that page to watch a book
whose id is 11. You can not get any parameter by using request.get(id).

So I use /book/11 and
application = webapp.WSGIApplication(
   [(r'^/book/(?P(bookid)$d+)$', Book)],
debug=True)
to get the bookid, and give it to Book.Get(self, bookid) function.


On Wed, Oct 15, 2008 at 10:49 PM, Alex Vartan [EMAIL PROTECTED] wrote:


 Ok, that makes sense. I guess that must be the reason why some of the
 example apps (written by bret taylor) use REquestHandler classes that
 subclass a BaseRequestHandler class that includes the original request
 object:

 def generate(self, template_name, template_values={}):
values = {
'request': self.request,
'user': users.GetCurrentUser(),
'login_url': users.CreateLoginURL(self.request.uri),
'logout_url': users.CreateLogoutUrl('http://' +
 self.request.host +
 '/logout'),
'application_name': 'Questioneer'
}
values.update(template_values)
directory = os.path.dirname(__file__)
path = os.path.join(directory, os.path.join('templates,',
 template_name))
self.response.out.write(template.render(path, values,
 debug=_DEBUG))


 This seems like a helpful idiom so that all of the original request
 variables for a get are available to the django template code for use
 in POST hidden fields.
 Correct interpretation?
