[web2py] Re: vps - memory problems
The problem of memory usage that you experience has nothing to do with the fact that code is executed at every request.Other users here do not experience the problem. In any case... Python is a language that does not provide garbage collection. It provides reference counting. This is a major limitation of the language. It fails to detect certain types of circular references. web2py has code to catch them by calling the garbage collection explicitly every 100 requests. Note every request because it would cause a slow down. Anyway, let's try to get to the bottom of this and isolate the problem. What OS? What Python version? what web2py version? what code? Massimo On Jun 3, 10:53 pm, Carlos carlosgali...@gmail.com wrote: Thanks for all the recommendations. But it still worries me that web2py (or uwsgi) does not automatically (a) cache/reuse unmodified code and (b) release memory after requests are served (or while idle), after each web request, and regardless of how small or big models actually are.

Reply 2:
open('/dev/urandom','r').write(''.join(chr(t) for t in ctokens))
In this line, you are attempting to open /dev/urandom for reading, and then
are attempting to write to it.
Instead, you need to read the data from /dev/urandom, and then open a new
file for writing to write your output.
Hope that helps!

[web2py] 1.96.3 is OUT
Just one minor change to deal with an error for system where users do not have permission to write to /dev/urandom (typically on shared hosts).
[web2py] Re: webfaction: Internal Server Error after upgrade to 1.96.2
On my Ubuntu 10.04 system /dev/urandom has mode 666 which means read and write for everyone. If it is not writeable on Webfaction for others then it is either a policy for a different Linux distribution or a policy of Webfaction. The idea behind writing to /dev/urandom is to seed the random number generator so the output read from the generator is less likely to be guessed which increases security.
Re: Re : Re: Re : Re: Re : Re: [web2py] Re: Email invitation
Can somebody please help me ? I would really want this to work.
I customized db.auth_user, as described in the book, to add a 'token'
field. I just added : Field('token', writable=False, readable=False,
default='').
Then, in the controllers, I modified default.py :
def user():
db.auth_user.insert(token=request.args(1))
return dict(form=auth())
Then in the models, I modified db.py :
def my_auth_processing(form):
if db(db.auth_user.token!='')
(db.invitation.token==db.auth_user.token):
return True
else :
return False
auth.settings.register_onvalidation.append(lambda form:
my_auth_processing(form))
But unfortunately no one is prevented from registering... So this does
not work.

[web2py] Re: webfaction: Internal Server Error after upgrade to 1.96.2
To add some more, on Ubuntu and according to man urandom all major Linux distributions since 2000 the file /etc/init.d/urandom saves the random number pool into a seed file and restores it on startup by writing it back to /dev/urandom.
Re: [web2py] Re: vps - memory problems
Do not stay with sqlite in production I don't agree http://www.sqlite.org/whentouse.html SQLite usually will work great as the database engine for low to medium traffic websites (which is to say, *99.9% of all websites*). The amount of web traffic that SQLite can handle depends, of course, on how heavily the website uses its database. Generally speaking, any site that gets fewer than 100K hits/day should work fine with SQLite. The 100K hits/day figure is a conservative estimate, not a hard upper bound. SQLite has been demonstrated to work with 10 times that amount of traffic first comment from http://stackoverflow.com/questions/54998/how-scalable-is-sqlite : As I mentioned in my first edit, database indexes dramatically reduce query time, but this is more of a general observation about databases than it is about SQLite. However, there is another trick you can use to speed up SQLite:transactionshttp://www.sqlite.org/lang_transaction.html . And we know that web2py puts every request in a transaction And great advices from another comment from the same page: If you want to speed things up with SQLite, do the following: - upgrade to SQLite 3.7.x - Enable write-ahead logginghttp://www.sqlite.org/draft/releaselog/3_7_0.html - Run the following pragma: PRAGMA cache_size = Number-of-pages; The default size (Number-of-pages) is 2000 pages, but if you raise that number, then you will raise the amount of data that is running straight out of memory.

[web2py] App-generating wizard crashes

I would question how many people would actually use it and whether it would be worth the effort to maintain. I'm not saying it isn't useful for newbies. I am saying that web2py newbies are probably early adopters and less likely to need or use such a wizard. Just my 2 cents.

I ran into small problem. When I define model:

The problem is that validation serves me an error eventhough no
validators are attachted to parent and I explicitly provided
notnull=False.
It shouldnt check in database unless I express so in the validator
this way it cannot realize the scenario to have parent or null ;]

[web2py] Re: vps - memory problems
Hi, I can finally point the specific part of my code where memory leaks: from gluon.tools import * w2p_recaptcha_xml = Recaptcha.xml def x_recaptcha_xml(self): return 'my own recaptcha xml' Recaptcha.xml = x_recaptcha_xml The above replaces Recaptcha's xml method wih my own. I know that in this specific case I can subclass Recaptcha and extend/override the xml method, but let's not discuss this for now. By doing it this way (direct replacement, instead of extend/override via subclass), everything works ok, except when I enable the yellow line (w2p_recaptcha_xml = Recaptcha.xml above). As soon as I enable this specific line (in yellow above) and restart uwsgi, memory just leaks after every single web request (much more noticeable when the models are very large in code), until the server stops responding due to very large memory consumption (after relatively few web requests). My question is why?, is it because w2p_recaptcha_xml retains the 'context' of everything and it just keeps adding and adding?, or how/why exactly does the above cause the memory leak?. I just want to understand the reasons. Thanks!, Carlos
