[appengine-java] XMPP Encoding problems/ XHTML-IM
Hi After having some trouble to figure out what the 'asXml(true)' method in the MessageBuilder class does I finally figured out how to get XHTML-IM style marked up messages to work. If you're having the same problems, please have a look at my blog post about that topic: http://blog.squix.ch/2011/02/sending-xmpp-messages-from-google-app.html What I still couldn't figure out is how to apply a specific encoding to the XHTML-IM part of the message. When I sent some none ASCII characters in a message I only get scrambled results. A message 'Warnstreiks bei der Telekom könnten in der kommenden Woche für Kunden spürbar werden.' is received by the client as 'Warnstreiks bei der Telekom k?nnten in der kommenden Woche f?r Kunden sp?rbar werden.' (the umlauts are replaced by question mark). I also tried to use StringEscapeUtils.escapeHtml(myMessage) to escape the special characters, but it seems that something in beetween escapes again... Digging in news groups also turned out that this had been an issue to the plain text message and had been resolved by the GAE team: http://code.google.com/p/googleappengine/issues/detail?id=2072 Does anyone have a solution for this nasty problem?

[appengine-java] Urgent: GAE app is incredibly slow!
I've got two apps (everdynamicsite and domoroi) which have *exacly same code *base and similar datastore content. everdynamicsite site is very very slow starting from last night domoroi is as quick as usual I enabled appstats, that shows great gaps beween datastore operations like below: @110ms *datastore_v3.Get* real=58ms api=66ms @2708ms *memcache.Get* real=15ms api=0ms But I'm not sure that these are cause for problems because for other requests appstats' Grand Total shows 88ms, but response times are still very-very slow! Does it mean some sort of environmental issue at GAE side? I'm confident that this issue is not with my local setup as other people get similar results at other locations. To me it looks like the request is hanged somewhere before it reaches everdynamicsite, as the request processing time (based on log records) is less than a second! Even /appstats/details?time=1298213007287 requests take tens of seconds before response is received Now few times in a row I get this message in the log file: 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) That looks really weird. What could be done to solve the problem?

[google-appengine] How do I determine the order of HTTP requests?
I periodically have a large number of requests (thousands) to my site in the space of a few seconds. I need to record the order in which the requests access the site so I can do downstream processing. The order does not have to be exact, I only need resolution down to 1 second: I don't care which order two requests are in if they are 10 ms apart. However I do care which order they are in if they are 1500 ms apart. The only problem is that I cannot figure out how to do this. I though about creating a datastore entity that contains a timestamp for each request to the site. (It doesn't matter if two or more entities have the same timestamp.) However I understand the clocks between machines in App Engine are not necessarily synchronised and could vary wildly. It would be ok for business logic if they only varied by 1-1.5 seconds at the most but I don't think this can be guaranteed. I thought about using memcache's atomic increment function instead of a timestamp for each new request but this could be wiped at any time so is no good. Even if the wipe occurs rarely, I cannot afford it to happen just once. How can I solve this type of problem?

[google-appengine] Re: How do I determine the order of HTTP requests?
I don't think it will be feasible with any accuracy. Your requests are going to be served by different running appengine instances .

[google-appengine] Re: Partial put() ?
I believe that by not explicitly setting indexing to False, you're getting an implicit index on every item (apart from non-idexables like Texts). If these item values change a lot, your put() may be quite expensive and slower than expected. You might also end up wondering why you've got so much storage related to indices. Even without values that change, your index structure is still very likely to greatly affect your put() performance. Are you sure this is what you want/ need? My limited experience has me now striving to push index updates into task queues whenever feasible to keep the on-line handler put() as fast as possible. This often results in a separate index-only db class linked to the original record via its id value. Doesn't solve every problem, but will certainly be much faster (again that statement is based on my limited experience). I'm starting to get used to this setup, and find it a fairly decent workaround to avoiding potential DeadlineExceeded issues in the on-line handler.

I have resulted into using DTO to provide the client information about my Entity. My DTO has the same getter and setter signatures just like it's respective Entity.

Some of my findings report that I either create the Entity on the client side so that GWT can find it or create an implementation of the Entity on the client side overriding all the necessary methods. I am not sure about the former as I believe the Entity is meant to be on the server because it needs access to JPA. On the later, I have no idea of how to implement that as the Entity needs access to JPA (GWT can't compile server code on the client side!). Any clues please.

[google-appengine] Re: How do I determine the order of HTTP requests?
I was just experimenting with a way to get multiple servers synchronized to within a second. Here's what I came up with: https://gist.github.com/836228 It grabs the date header off of a fetch request and calculates the delta between the server's time and the canonical time. Then when you call synchronize(date) it subtracts that delta from the supplied datetime. The date header doesn't return microseconds, and you have to consider that the round-trip time adds inaccuracy, so I think +/- 1 second is the best that can be done. In my brief tests I was seeing that the app engine time was basically the same as canonical time without doing any of this hackery. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

Re: [google-appengine] Re: How do I determine the order of HTTP requests?
Calvin, does Google serve robots.txt off of one machine? Otherwise it seems like you might be making a request to another cluster with the same problem to 'adjust' your times. Yeah, this hack is based on the assumption that Google is more careful about maintaining the clocks on their www servers than they are about the app engine cluster, which could be false. The hack could be pointed at another page that is known to be served off a single server. Since the time is only requested once per app engine instance (unverified assumption), it shouldn't put too heavy a load on that page. -- You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Need help with redirection
Hi Robert,
Thanks for the response!
I have practiced the guestbook app 2 times for learning, and now the
3rd time, as I'm following it for making my own app.
My data comes from some API, where in I'm passing a keyword. My
problem is, I want to use a set of template values commonly throughout
the site, no matter to what URL I'm going to. For example, if I want a
value 'site-header':'Hello!', I want it to be same on all the pages. I
have to pass it every time template.render function renders a page! I
want to do it so that I can have a templating sort of flow for the
site. Like, any where I call {{site-header}}, it should get the same
value.
And one more doubt, how to redirect to a third party site from my app?
I made a tutorial for the app I'm making, and I want to redirect
people to it for learning it. I tried this:
My div='nav' has a like to my site: a href='/learn'Learn/a
My main.py file:
app = webapp.WSGIApplication([ ('/', Init),
('/learn', Learn)]
class Learn(webapp.RequestHandler):
def get(self):
self.redirect('myblog.com')
This isn't working! When I click the link, I get
http://localhost:8080/myblog.com
in the address bar (I'm working locally) and I tried hard coding the
address, but it doesn't work either!
Am I doing something wrong?
Thanks,
Rutwick

Hi GAE Gurus,
I'm fairly new to GAE. I'm making an APP which gets some data from a

the API. The problem is, when someone first opens the homepage, that

the 'template_values' dictionary, which also contains the site title,
description etc. Once a person enters a keyword and clicks submit, I
want the returned data to be displayed in same div. How to I redirect
to the homepage on submitting the keyword, along with the returned
data and the old values? I'm not using a datastore so I couldn't use
the method given in the guestbook app which gets the values from the
