Hi,
In my application I would like AJAX invoked GETs and POSTs to edit the
state of the application by editing attributes in the session. I'm having
trouble though when the requests overlap, meaning not all changes to the
state are saved.
Below is a minimal example to reproduce the problem. First visit /, then
/status to see that only one of the session attributes is updated, not
both. /status shows for me "state1 = 1 state2 = 0"
Thanks in advance for any help,
Matt
import web, time
urls = (
'/', 'index',
'/1', 'one',
'/2', 'two',
'/status', 'status',
)
web.config.debug = False
app = web.application(urls, globals())
session = web.session.Session(app, web.session.DiskStore('sessions'))
class one(object):
def GET(self):
session.state1 = 1
time.sleep(1)
return "done"
class two(object):
def GET(self):
session.state2 = 1
return "done"
class index(object):
def GET(self):
session["state1"] = 0
session["state2"] = 0
return """
<iframe src="/1"></iframe><iframe src="/2"></iframe><a
href="/status">status</a>
"""
class status(object):
def GET(self):
out = ""
if "state1" in session.keys() :
out += "state1 = " + str(session["state1"])
else :
out += "state1 not set"
if "state2" in session.keys() :
out += " state2 = " + str(session["state2"])
else :
out += "state2 not set"
return out
if __name__ == '__main__':
app.run()
