Hi,
I'm just wondering if anyone has experienced the same problem or not.
Basically, I get a segmentation fault (scheduler process killed by signal
11) if I try to start more than one scheduler under OS X.
The problem can be reproduced with the built-in welcome app by adding a
models/scheduler.py:
from gluon.scheduler import Scheduler
SCHEDULER = Scheduler(db)
and then start the scheduler like this:
./web2py -K welcome,welcome
I'm running web2py R-2.9.11 with python 2.7.8 (also same result with
apple's python 2.7.6) on OS X 10.10.1(also got the same result on Maverick).
I've managed to track down the problem to the getproxies() call in urllib
which leads me to this bug: http://bugs.python.org/issue9405
By following the suggestion in the bug report, I was able to work around
this problem by this patch:
diff --git a/gluon/widget.py b/gluon/widget.py
index cf885ae..62a38ee 100644
--- a/gluon/widget.py
+++ b/gluon/widget.py

+ import urllib

for app in apps:
app_, code = get_code_for_scheduler(app, options)
if not app_:
Just wanted to throw this out in case anyone meets the problem.
Thanks
Jack
