[google-appengine] Re: Quota numbers seem wrong
Quotas are showing weird bloated stuck values for one of my apps too appid=sodso-reminders How often are quota details updated ?? Here are some of the wrong values - Task Queue API Calls = 100 ?? I didn't make any calls to the task queue, then how come its showing 100 ? - Requests = 1800 ?? This seems to be stuck at this value forever - Mail API Calls = 100 and Recipients Emailed = 20 ?? 100 mail calls is strange with Recipients as 20..this value seems to be stuck at this number.. - A few hours ago I made around 1500 calls to XMPP with 1 recipient each and the Quota was then showing it as XMPP API Calls = 50,000 !!! and Recipients Messaged = 50,000 !! thats absolutely bizarre !!! Google, Can someone pls look into these quota values issues ? I believe the recently released 1.3.8 version might have caused all these quota related problems ? Earlier it looked to be Ok.

[google-appengine] Re: URL manage
yes, thats easy in GAE Python should be similar in Java too (i guess) the URL supports vars as described below - http://code.google.com/appengine/docs/python/config/appconfig.html#About_app_yaml URL and file path patterns use POSIX extended regular expression syntax, excluding collating elements and collation classes. Back- references to grouped matches (e.g. \1) are supported, as are these Perl extensions: \w \W \s \S \d \D (This is similar to Codesite search, plus back-reference support.) cheers.

Re: [google-appengine] Re: URL manage
www.urapp.com/urldomainname
1) your app.yaml file will have this handler
handlers:
- url: /.+
script: code.py
2) code.py will have something like this
class URLHandler(webapp.RequestHandler):
def get(self):
var1 = self.request.path #this will give you everything after the
www.myapp.com
# import os
# print os.environ # u can use this dict as well for whatever values u
r looking for from the incoming req
def main():
run_wsgi_app(webapp.WSGIApplication([('/.+', URLHandler)]))

[google-appengine] Re: Cron scheduling at runtime
this is easily possible using command script. refer here - http://code.google.com/appengine/docs/java/tools/uploadinganapp.html#Command_Line_Arguments you will just need to create a small script which will run the script and hence upload the updated cron using update_cron optionread the above article for full details thanks.

[google-appengine] Re: datastore advice?
Hi Ikan Lan, I have seen this on so many discussions here in the forums - "A best practice, however, is to keep entity groups as small as possible" As far as I understand it, one Model class should not have too many records i.e. one table should not have many records Isn't this strange ? When we talk of GAE, we talk of scalability but if the best practice says to limit ther records to only a few in a Model class, what use is the scalability for ? If we store millions fo records (for eg- customer records) in one db.Model table, are you saying it would really impact the performance. Please correct me if I am wrong. I am unclear if my app can survive on GAE if its working with millions of records in one db.Model table ?? Thanks, Sodso On Oct 27, 11:27 pm, "Ikai Lan (Google)" wrote: > Generally speaking: no.

[google-appengine] Re: datastore advice?
my apologies for the word typo, i meant the same but my question still remains - if we have to store 1 million customer records, do we create 100 different "Kinds" ~= Entity Groups ~= db.Model and distribute those 1 million records among those entity groups ? then what about scalability ? does this mean === more records = mroe entity groups to be created ? isnt this an awkward of doing simple things ? thanks.

maybe something like this will work - 1) add a REPLY_TO address to each email sent, for eg - donotre...@yourdomain.com 2) foward all mails received at donotre...@yourdomain.com to boun...@yourappid.appspotmail.com 3) receive incoming mails at boun...@yourappid.appspotmail.com and check the subject like and body for strings like Delivery failed error etc (you can try this out with some bad emails bouncing back) and hence remove the email address from your mailing list cheers ! -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.

[google-appengine] How to kill a task queue job programatically ?
How to kill a task queue job programatically ? I am using a chained task approach but many a times the chains branch off into multiple parallel task chains due to TransientError etc, for eg - starting with just 2 tasks (task chains), today I saw them multiply into 4 task chains (total of 8 tasks). I will now start using named tasks (as suggested in my some other posts) but is there a way of accessing the tasks running / enqueued in a queue and killing them using program code ??
