[google-appengine] Breaking my head on Opensearch
I'm trying to implement an Opensearch XML solution in one of my apps. But IE8 seems to be having some problems with it. I think it might have to do with encoding or content-type issues.

[google-appengine] Duplicating static serving

So I was wondering: How can I serve files dynamically (e.g. templates), so that the result is exactly the same as when serving dynamically?

I am currently trying to develop an app that uses Google Voice's new email/sms functionality. However, when I send an email from my app to the correct email address, it simply will not go through.

[google-appengine] Actually Using Offset
I need to perform a simple ordering query (descending rank) on my
datastore. The default query looks like:
query.order('-rank')
However, I now need to perform paging. I attempted doing:
query.filter('__key__ ', bookmark)
query.order('-rank')
query.order('__key__')
This won't work though because it expects the ordering of the key to
go first.
So I modified it to look like:
query.filter('__key__ ', bookmark)
query.order('__key__')
query.order('-rank')
However, this doesn't produce the desired results.
So my question is, how can I get around this? And if there is no way,
should I just use offset and limit my users to 1000? What should I do?

[google-appengine] Re: Simultaneous Requests
Actually In terms of requests per second I was seeing was around 8
[didn't pay constant refresh attention]... Strangely though, the total
number of requests didn't accurately reflect the actual requests I
performed (in the dashboard -- not in the quota details page). This
may be due to some bug in the system. It doesn't really matter though
because the dashboard view seems to only be an overview, not for
accuracy...
Another thing: no matter how many threads I have there will always be
timeouts. I tried using only one thread (i.e. just running a python
for loop), there were a total of two timeouts. As the number of
threads increase, the number of timeouts increase... Additionally,
when a timeout occurs all the threads seem to fail simultaneously.
They continue to fail for a short period of time, and then they all
resume together.
Just a bit of information that I gathered from quite a bit of
debugging...

[google-appengine] Re: Simultaneous Requests
Wow Doesn't seem like GAE is happy with this arrangement:
I set up a simple system like so (in python)
[code]
import threading
import urllib2
class MyThread ( threading.Thread ):
def __init__ (self,j):
threading.Thread.__init__(self)
self.j=j
self.html=''
def run ( self ):
for x in xrange(500):
try:
response = urllib2.urlopen('http://the test
url')
html = response.read()
self.html=html
except urllib2.HTTPError, e:
print e.code
except urllib2.URLError, e:
print e.reason
# at end of thread life
print self.html
#init threads (10)
for x in xrange ( 10 ):
z=MyThread(x)
z.start()
[/code]
I ran this code on the client side. It ran fine but at approximately
100 requests it began to return Operation Timed Out Errors (code
10060). This is probably due to some Denial of Service protection by
GAE firewalls (?)
Is there any way for me to tell GAE that this is my app, and it's
legit, or is there any way to work around it?
[note: on the server side, nothing turned up on these errors which
leads me to believe it was a very low level protection]

I am currently working on a way to mass email [in a short period of time] using Google App Engine. I figured that as of now the best way to do this would be to run many requests in parallel. I was wondering if my app would accept many requests at once, and if so what would the limit be [in the paid version]? Would this work? Is this the best way to do this? As for implementing the parallel requests I figured the simplest way would be to use the python threading. I was wondering if using AJAX would be any better, or if it would even work for parallel requests??

[google-appengine] Re: Twitter - rate limit exceeded
I could think of a rather simple solution for twitter: Just give everyone an API key that they use to authenticate, and make the limits based on the key instead of the IP addresses. No?

[google-appengine] Re: Custom Login System
If that's what's coming from the browser, then anyone else can just sniff that hash and send it as the password with the username. Not really, because you can simply tell the client to hash the password with some random number (or string) that you sent to the browser... Otherwise, though, you are correct. And even if I do use openID, or the like, I also wanted to know about securing the cookie (or session), because even in such a situation they only perform the password check. The rest is in the applications hands.

In the end you're relying on data from the client being secure, which is bad. I'd suggest, if you don't want to use the Google User API, you look into still using other ID providers, such as OpenID, Oauth, or Facebook connect. They will handle the login via SSL on their end, and the account validation would happen via urlfetch between your application and the provider, leaving no traffic to be sniffed on the users network. If you really need a unique user system, I suppose you could set up a VPS server and have it act as an OpenID provider. One thought that just hit me as I writing this up is you could also use the build in application.appspot.com ssl that google provides you to handle the login by making it an OpenID provider. I believe there's a sample application out there for making an OpenID provider on GAE. Then your application, if you're using your own domain name, could urlfetch to itself for that portion of the authentication, in order to get the cookie domain set correctly for your sessions. This is something that would make an interesting little project, I wish I had time for.

The current token, plus previous two, are stored and are valid on requests in order to not cause problems with sites who's pages may make multiple requests (AJAX oriented sites). It also includes a middleware class so you can plug it in and use it directly with memcache. Version 1.1.1 is the current release, and the next release will include some new functionality to try and increase the performance by relying more on memcache (while still using the datastore in order to provide a completely reliable solution). It already uses both, but I'm working on cutting down the amount of writes. It's BSD licensed, open source. There are no fees or attribution requirements for it's use.

That way the contents of the cookie are no use to anyone, all useful info is stored in memcache, where attackers can't get it. - Store a hash of the password on appengine, not the password itself. This means admin cannot steal passwords, as well as allowing for safe transport of the password. - Javascript on your login form should first hash the password, then hash the result with a salt - say the session id. The extra salted hash prevents a sniffer from simply sending the hash to login, and also guards against using rainbow tables to discover the password. Make sure you destroy the field containing the original password, so it isn't sent in clear along with the hash! - On appengine, hash the stored password hash with the salt and compare with the sent hash - they should be the same. - I usually disable the account if I get three wrong passwords, to prevent dictionary attacks. This requires some admin work to handle users who've been locked out, but means you don't need to implement captchas. - Authentication is only the first step - you need to keep security at the top of your agenda throughout the whole application. For instance, if you have a url like fox.delete?id=123 that deletes a user's fox, always check that 123 actually belongs to this user. Otherwise users could delete other user's foxes by retyping the url. gmemsess is athttp://code.google.com/p/gmemsess/ Cheers! Greg.

('/article/([\d]+)', Article)
With the above rule, the matched values are passed to the handler, in
order. So in Article you'll have the method get(self, article_id),
which receives the article id from the matched rule.
[and is there any advantage to doing query strings in this fashion?]
Well, sometimes query strings are more convenient, but in many times
you would want to certify that only url's with minimally valid
parameters (in the above example, an integer) will match. With ?id=20,
you'll have to check if an id is passed in the handler method, *after*
the dispatch process. It's also a matter of aesthetics and, most
important, how your handlers are organized.

Why is it hard work, from my understanding it simply requires sending an email to X amount of people. I could probably set up a PHP script to do this rather quickly...

Well another point is that if I want to send time-sensitive info, it would be impossible (i.e. with your method, you are running the sending throughout the entire day, but in some cases almost-instant sending is required). Another problem worth mentioning is that mass-fetching from the datastore (all the emails) would not work in the current appengine...

Your solution would definitely not work well at that point! I agree that it's far from being perfect, but I don't see why it wouldn't scale. I currently send about 100 emails a day, if this number grows, I would just need to buy more quota and ping the mail sender URL more frequently (every 17 seconds for 5,000 emails a day).

[google-appengine] Re: Interesting How-to Datastore Question
Well I figured out a sort of fix (similar to urs but doesn't require
pinging from external box):
I basically added a list property to MainListOfArticles that contains
all the user objects that commented on that specific article [I'll
call it CommentsOnArticles]. So every time someone comments I add a
comment to the CommentsOnArticles (once for each user!), and also
update the MainListOfArticles entity. I also added an entity called
lastCommentedOnDate which is updated every time a new user comments.
So when a user logs in I simply use s/t like the following code
(snipped out) to fetch all his articles that were commented on:
q=db.Query(MainListOfArticles)
q.filter('usersThatCommented =',currentUser)
q.order('-lastCommentedOnDate') //ascending or descending depending on
ur preference
results = q.fetch(5)
You will also need a special index for this query (that usually is
added automatically through the SDK)
The only problem is that if ___too___ (it would have to be like 1000s,
I think) many different users comment on one single article you could
go over the 1 MB per entity limit...
