[google-appengine] ContactsService, no attribute 'HTTPSConnection'
Hi people,
I'm having problems when trying to retreive google contacts using
programatic login, let me show you my code...
class MainPage(webapp.RequestHandler):
def get(self):
gd_client = gdata.contacts.service.ContactsService()
gd_client.email = '[EMAIL PROTECTED]'
gd_client.password = 'password'
gd_client.source = 'exampleCo-exampleApp-1'
gd_client.ProgrammaticLogin()
when the code executes I get the following error...

Any idea?
I'm using programatic login because authsub login was giving me a lot
of headaches , maybe I need to study a more python/GAE.
if you have a working sample of google contacts service using authsub
login , that would be very useful too!
Thanks in advance.

[google-appengine] Re: suddenly, a new error in Cheetah in production GAE, doesn't occur in SDK
Hi Ben, The recent maintenance included some changes to db.py, including adding a has_key function, which seems to be causing the error with template rendering. The new SDK has not yet been released, but the easiest/quickest fix would be to take the google.appengine.ext.db __init__.py file from 1.1.5, rename it, and included it with your application. Just change the imports, replacing from google.appengine.ext import db with from Db import db (assuming you changed the name of __init__.py to Db.py, for instance). Hope this helps, sorry for the confusion! -Marzia On Fri, Nov 14, 2008 at 3:19 PM, Ben Adida [EMAIL PROTECTED] wrote: Hi Marzia, Thanks again for your help.

[google-appengine] Speed up a slow development appserver by taming index history file
We're going to a trade conference next week to demo our app, but we can't afford $5000 for an Internet connection. No problem, we thought, we'll just demo it off of the development appserver. So we're trying to work around the sluggishness with which the dev appserver responds to requests. Yet no matter what the request (a tiny static file, an immediate HTTP response through Django, a memcache hit, whatever), debug or not, with tons of data or no data in the datastore, every response takes 1.5 seconds. Brutal. I finally figure out why the development appserver is so slow (and has always been getting slower, I now realize): on every request, it's spending nearly 1.5 seconds parsing our long local datastore history file, even if the request doesn't explicitly query the datastore. I hadn't even thought of this; we manage the size of the datastore file, but apparently the history file had never been cleared. It had grown to 813 KB with 11315 queries (and that's from my machine alone). So yeah, that was it. Everything runs nigh-instantly now. I haven't seen any references to this problem elsewhere, or any warnings that a long history file can impact performance, so maybe this'll help someone avoid our fate. Perhaps it can be mentioned in the docs. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

appengine is good at things which are really really hard to do in traditional mysql, but a few things which are easy in mysql are significantly more complicated in appengine.

Choose the right tool for the right job now, or wait until appengine has been better adapted to the typical developer workflow (or will the developers work flow adapt to appengine ???) just my thoughts regards Roberto On Nov 15, 10:34 pm, cm_gui [EMAIL PROTECTED] wrote: Dear Sal Can you explain why you disagree ?

No,
I am just using the built-in 0.96 templating system and the 'safe'

It that case you should un-escape with the safe filter:

I see two reasons why it doesn't work as expeced: 1. Your html is already escaped in the datastore. 2.

[google-appengine] Re: How to find the total number of records in Datastore
Having a single counter for records in a distributed system will create a bottleneck when the application needs to scale to handle an increased load (such as an increased number of simultaneous users). One solution is to use a collection of counters (called a sharded counter in the video below) to solve the load scaling problem. This is described from about 0:40:40 in this video: http://www.youtube.com/watch?v=FZ-aagsMv40 The Google App Engine team could perhaps have included a general counter in the API, but one risk is that application developers then would overuse counters without having design for distributed systems in mind. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Is it a webserver bug!?
My app use a para only, but if I supply only one, no record found. If I supply 2 or more paras, there are records found. eg. http://1.latest.cele.appspot.com/product/list?cellId=601name=a return 2 records, but http://1.latest.cele.appspot.com/product/list?cellId=601 return none. I only use 'cellId' as para in my application.

[google-appengine] Re: Observing GAE Scalability (or trying to ...)
David, It sounds like a very interesting and useful experiment you're contemplating. I can't figure out why some people are so negative on this, unless they're insiders and afraid of some unfortunate truths being discovered, which I certainly hope is not the case. This is about discovery and the pursuit of knowledge, in the context of a brand new and exciting technology platform. What in the world is wrong with that? It may be that your specific 3 tests aren't everybody's ideal tests to run. Then how about people suggest other tests instead of shooting down the whole idea? And it is most definitely NOT necessary to build a complex application to do benchmarking comparisons. In fact it would be counter-productive to do so, as it would take extra development time and make identifying actual bottlenecks cumbersome. Please continue your work and share the results with us. I'm sure the non-vocal majority will appreciate the fruits of your labor, and I hope the vocal minority can try to be constructive in their criticisms.

Now, I would really like to be able to demonstrate to myself, with a simple toy application, that GAE can out-scale what a single dedicated host can do. When I set off on this experiment, I was expecting it to be easy to demonstrate that GAE can handle some request pattern which my PC (temporarily running as a LAMP [with mod_python] box) would grind to a halt on. Perhaps my results are just an artifact of the current quotas, but more likely my test applications are stressing scalability in the directions GAE scales. I'll describe my current approach and let people here help point in the right direction (hopefully). I use a program like htttperf to spawn requests from a cluster of (~20) machines. I specify a page to request, the target request per second rate, and the duration of the test. I also specify a time period over which the requests per second rate grows linearly from 0 to the target. I'm currently trying parameters in the range of 10-20 reqs/ sec for a duration of a few minutes after a ramp-up of a few minutes. I have tried this with three separate toy applications: 1) A python script which sleeps, say for 0.1sec, then returns a trivial page. This was a silly idea b/c the PC simply spawns tons of processes which are doing nothing and easily keeps up with even quite high reqs per sec. GAE dies much sooner since sleeping seems to count against your CPU time. 2) A python script which generates a random number through an process which is intentionally slow -- so that it takes about 0.1sec on both my PC and GAE for an individual request. At 20 reqs/sec, it seems like the (dual-corE) PC should die as requests come in faster than it can handle them while GAE should be able to scale -- but GAE ends up going over quota. Maybe I need to revisit the ramping up process and make sure it is really working like I think? 3) Use a DB with string-integer pairs. The strings are an average of 50B. Have a python script which queries for the first N records greater than some random string. Then return the sum of some of the integers from these N records (randomly chosen). The PC is running MySQL and does the same select, and does the summation by iterating over the N records like the GAE app to be fair (SQL could probably be even faster by doing the aggregation in the query rather than in python). With N=20 and the DB having about 300k records, GAE unfortunately times out while the PC version is almost instantaneous (for individual requests). What ideas do you have for demonstrating that GAE can scale better than PC, at least under certain conditions? I have no doubt that I'm missing something. For now, I'm going to focus on the ramp-up portion and make sure that's working correctly, though I imagine there are probably better approaches than the above three for trying to demonstrate this and I'd love to hear your thoughts. :) Thanks. ~ David --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Re: Observing GAE Scalability (or trying to ...)
I guess it's difficult to do a really accurate scalability test for simulating a huge number of simultaneous users. I heard one interesting comment in a video (don't remember which video) about Google App Engine though. To make an accurate load test on Google App Engine it has to be done over a period of time that allows Google App Engine to spawn new server instances. To just go from small load to suddenly hitting the App Engine with a massive number of hits will not give an accurate results since the App Engine must be given some time to adapt to the increased load (to spawn new server instances). I can imagine something like a binary tree of servers. At low load only one server is handling requests. When the load increases above a certain threshold then two new servers are activated to handle requests, and so on in a binary tree fashion. This is just a guess. How the scalability is done in GAE may be something entirely different, but as I understand it GAE has some form of gradual growth of scalability. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.

[google-appengine] Google Apps Account + Google Account = Missing apps?
Hey :-) I used to (up until yesterday) have two different accounts. One is this one, which was a pure Google Apps account. The other is a pure Google account (quite an old GMail address). I don't use my GMail account anymore, because I have GMail on my Google Apps account. I didn't know you could create real Google accounts from non-GMail domains (sorry, I know this sounds stupid), but I found out today and I did. In an effort to get rid of the last thing I was using my GMail account for (my GAE app), I added my Google Apps account (the one I'm posting with) as a developer to my app. I got the confirmation mail and used the Google account activation link, not the Google Apps one (after all, it's a Google account-linked GAE app, not a Google Apps one -- it's hosted at appspot.com). When I log in on my original account, I see both accounts as developers on my app. When I log in on this account, I see zero apps when I go to the admin interface (http://appspot.google.com). I'm not 100% sure that's what's going on, but it's the best reasonable cause I can come up with. Is it even possible to use this email as a real, proper Google account?
