[google-appengine] Django version conflicts - now also in production
In my app I use Django version 1.0, in stead of the default version
0.96.
To do this I have the following statements in my application entry
point script (as per instructions):
from google.appengine.dist import use_library
use_library('django', '1.0')
This has from the start (the last 16 months) often caused an error
which has forced me to restart my developer environment.
But I have thought nothing of it, as it has worked flawlessy in
production - until now.
Now, the last couple of weeks I have gotten the same type of error a
couple of times in production.
The only cure has been to quickly upload a new version and make it
default. Luckily I have had non-altered code at hand so I could do
this quickly and easily. But I might have been in the middle of
altering my code for a next version. What then? ... (Yes, yes. I
know. Version controlled code repository.) But I digress.
Anyways. Why has this error now started appearing?
And what is to be done about it?!
Here is the error message from the log:
10-18 04:03AM 17.255
:
django 1.0 was requested, but 0.96.4.None is already in use

I don't. But has it now been added by Google in GAE?
Can I remove it from there?

[google-appengine] Re: Django version conflicts - now also in production
Yeah. Better check with your wife about that. ;-)
The dev-server I can live with, but in production is serious.
And it has only starter happening recently.
I don't know how to formally log it as an error. If you do, please do
it.
(And share what you did.)

[google-appengine] Re: Django version conflicts - now also in production
Well. I saw now other sollution. The errors were hurting me.
I reverted to using the default version of Django (0.96.x).
I simply removed the use_library statement.
And i my case I only had to fix a couple of temlates (by removing the
safe-filter),
and one client had to be fixed, as I guess the HttResponseRedirect in
0.96 doesn't seem to reslove a relative url to an absolute one.
But no problem, though.
Oh. And don't forget to switch to using the documentation for 0.96.
Now back to my care-free life. ;-)

[google-appengine] "Scanning files on local disk"
Every time I uppload to appengine, the script first does: Scanning files on local disk. Scanned 500 files. Scanned 1000 files. Scanned 1500 files. Scanned 2000 files. Scanned 2500 files. Scanned 3000 files. Scanned 3500 files. Scanned 4000 files. Is there some way to find out: a. What/where all these scanned files are? b.

[google-appengine] DoS blocking vs multiple users on single IP
We provide a commercial web application to schools (in Norway). Schools typically have 20-30 kids pr class - all using web application at the same time - under the direction of a teacher. And all behind single IP address. So now you have 20-30 kids pr class, each generating 20-30 request to our service within maybe 30 minutes, all through the same exterior IP. All the GAE sees is a sudden massive onslaught on a site from a singe IP, and so it blocks that IP - with an appropriate message (but missing the capcha). This happened for the first time yesterday morning: I travelled 2000 km to visit a school and train teacher and pupils. The first class went fine 08:30 (UTC+1). But when the second class started up (at 09:15) they were almost immediately blocked. And so we waited. We tried another an hour later. No go! But two hours after that another group was successful. Our business is schools. Schools will all typically follow this pattern. We can't have our system cut of unpredictably like this. Maintaining some sort of white-list (shools IPs) is also not a viable option. Can we at least adjust the limit for blocking? Or better yet, how about some kind of API? (A variying code the client can put in the header which will authenticate it for a number of request ...) Or, deacitvate automatic blocking, operate with blacklist only, and risk the higher costs of possible attacks? This is critical for us!

[google-appengine] Re: DoS blocking vs multiple users on single IP
Yes. Billing is enabled. (Must be to use BlobStore). I agree, 30x30 isn't much. But does your dads school use a range of IP-addresses, or just one single address?
