Hello Shwetanka,
Just looking at this traceback, the error looks like it was raised at
starpy/fastagi.py:145, and the Deferred in question had its callback
called at starpy/fastagi.py:120. Both are starpy code.
I'd suggest asking the starpy people. This traceback makes it look like
the error
Yes, I was expecting you to wrap item.obsolete() and renew(data) in
try/except, as needed. If you want a clean but slightly slower way to do
that, how about something like:
def getCachedResult(cache, key):
def release(result, item):
item.release()
return result
d
If you don't like that construct, perhaps this one is nicer:
from twisted.internet.defer import maybeDeferred
def getCachedResult(cache, key):
def _readItem(item):
if item.obsolete():
return None
return item.read()
def _gotResult(item):
def _release

Hi Sergey

Something like the below (untested) will do the job. You'd have to make
sure that cache.open returned a deferred that fails with NotFound in case
things don't work out.
It would be simpler to translate your code using inlineC
Hi,
What is currently the recommended option for letting Twisted
applications communicate with SOAP services?
Cheers,

I would probably write it something like this:
def getC
How to rewrite this regular function with Deferred-style?
def getCachedResult(cache, key):
try:
item = cache.open(key)
except NotFound:
return None
try:
if item.obsolete():
return None
data = item.read()
finally:
item.r
Hi
I'm using twisted api with starpy to make a conference call. After a
successful call this error is logged in my log file
