Hi,
am very new to uWSGI and I am having a terrible time trying to get
anything to work. Here is how I installed uwsgi UWSGI_PROFILE=gevent
pip install http://projects.unbit.it/downloads/uwsgi-lts.tar.gz
Below is the the command use
sudo /usr/local/bin/uwsgi --loop gevent --socket :8030 --wsgi-file
/home/ubuntu/workspace/uwsgiServer.py --master --async 5
--enable-threads --listen 100 --uid root
*** Starting uWSGI 1.2.3 (64bit) on [Wed Jun 13 18:03:30 2012] ***

1) Why does it say that the max file descriptor number: 1024
I have a sysctl file optimized for very high traffic. ulimit is unlimited.
2) Per the below code that is supposed to be executed every 15
seconds....this is the output I get. I used the example
from uwsgidecorators import *
import uwsgi
@timer(15, target='spooler')
def hello_world(signum):
r_main_writes.set('foo','bar')
could not deliver signal 0 to the spooler
uwsgi_signal_send(): Bad file descriptor [signal.c line 412]
could not deliver signal 0 to the spooler
uwsgi_signal_send(): Bad file descriptor [signal.c line 412]
could not deliver signal 0 to the spooler
uwsgi_signal_send(): Bad file descriptor [signal.c line 412]
could not deliver signal 0 to the spooler
uwsgi_signal_send(): Bad file descriptor [signal.c line 412]
could not deliver signal 0 to the spooler
3) I am using bottle.py. Just trying to do a simple write does not
work but yet works outside of uwsgi.
import gevent
import gevent.socket
from bottle import route, run, default_app, request, response
import redis
try:
#http://comments.gmane.org/gmane.comp.python.wsgi.uwsgi.general/3606
from uwsgidecorators import *
import uwsgi
@timer(15, target='spooler')
def hello_world(signum):
r_main_writes.set('foo','bar')
except ImportError:
pass
@route('/upixel/')
@route('/upixel')
def upixel():
yield 'pixel'
# this task will goes on after request end
#gevent.spawn(bidderRedisWrite)
if __name__ == "__main__":
# Interactive mode
run(host='localhost', port=8070)
else:
# Mod WSGI launch
os.chdir(os.path.dirname(__file__))
application = default_app()
