I'm reading up on strace now. in the meanwhile, here is the MVC code (not
sure if I can attach a file to google groups)….
Model:
-Nothing. I have an empty model file. Other than the default settings that
come with a new controller.
Ordinarily I am using a Model and writing to the SQLite db. But this is the
simplest case I could make that
still replicates the problem.
View:
-Don't have this either. I'm only ever returning a json object via REST so
there's no need for a view.
Controller:
You can see some of what normally gets loaded, which I've commented
out. I also tried to see if gc or cache would help.
I've never used these before though so I may have been doing it
incorrectly.
the RESTful query would look something like:
http://domain.com/memclimb/request.json?jo={"Test":"memory"}
"request.py" (controller)...
_______vv______
@request.restful()
#@cache(request.env.path_info,time_expire=10,cache_model=cache.ram)
def test():
#import gc
import gluon.contrib.simplejson
response.view = 'generic.'+request.extension
#gc.enable()
def GET(*args,**vars):
jsonObject = request.vars.jo
obj = gluon.contrib.simplejson.loads(jsonObject)
return {'message': 'testing Memory.'}
#gc.collect()
return locals()
_______^^________
Only seems to be a problem under high traffic. So I created this python script
and ran 10 instances of it from another machine.
It's common for our site to have >100 trying to hit it at about the same time,
but I can see the memory climb even with only 10.
"testLoad.py"...
________vv________
#!/usr/bin/env python
import sys
import os
import urllib
def main():
for i in range(1000):
result =
urllib.urlopen('https://domain.com/memclimb/request/test.json?jo={"Test":"memory"}')
json = result.read()
print "done…\n\t%s"%json
if __name__ == '__main__':
main()
