Re: [Twisted-Python] self.channel.writeHeaders(version, code, reason, headers)\nbuiltins.AttributeError: \'NoneType\' object has no attribute \'writeHeaders\'\

To add on this.. Glpyh's suggestion was to not call `request.close()` if notifyFinish() deferred has been fired. But I am not sure how do I check if that deffered is available or not. On Mon, Aug 5, 2019 at 2:26 PM Waqar Khan wrote: > Hi Jean, > Yeah, actually that is the example that I

Re: [Twisted-Python] self.channel.writeHeaders(version, code, reason, headers)\nbuiltins.AttributeError: \'NoneType\' object has no attribute \'writeHeaders\'\

Hi Jean, Yeah, actually that is the example that I looked into and implemented my code. The issue I have is.. still some instances of interrupted responses are not trapped. Copying pasting my minimal implementation for your convinence def print_json_response(resp, request):

False alarm. Seems like there are some sneaky conditions when I get the error message. Like before, I use to get notifyFinish error everytime. Now, it seems that 6/10 times things are "clean" but then 4/10 times there are notifyFinish errors. Wondering on your suggestion. How do I ensure whether

Hi Glyph, I am not sure I understand. Is there a method/variable in request which keeps a track whether notifyFinish has been fired.. So, I can do something like. if not request.hasFiredNotifyFinish: request.finish() ?? I have sort of able to get around this issue.. though I can't

Ah yes.. That is true.. If I comment out request.finish() (Here is the doc which I tried to followed: https://twistedmatrix.com/documents/13.0.0/web/howto/web-in-60/interrupted.html ) Then actually.. when I try to test out the code... (via curl or like doing requests.get .. to the URI).. it is

Hi Glyph, Thanks for the suggestion. I tried the suggestion.. While it fixes the self.channel NoneType issue.. It creates another issue. Traceback (most recent call last): File "/usr/local/Cellar/python/3.7.1/Frameworks/Python.framework/Versions/3.7/lib/python3.7/asyncio/events.py", line 88,

Hi, I have a twisted server. And I have been seeing this annoying issue. Normally. when i develop and test it out. everything is fine.. But then I try to loadtest is via https://locust.io/ Again, everything is fine.. until I "stop" the test. Then, I see this 'Traceback (most recent call
