This is great Jean-Paul, see so much for me to learn. I didn't realize that
you could break the propagation of Cancel errors like that. thanks!

So I have a simple question from all this. Is there a twisted idiom I can
use so that deferred returned from a Klein route are not canceled if the
client resets the connection? It's fine if it's before I've gotten the
request body, but once I've gotten the request body I want all deferreds to
succe
Well, I've dealt with this issue with other languages. Not sure how to deal
with it in Klein/Twisted. This operation is idempotent so I suppose what
I'd like to happen is have the whole chain of deferred's succeed but then
just not be able to write the response to the socket -- but not interrupt
th
If you're dealing with lots of clients on the public internet, sometimes this
is just gonna happen, for a variety of reasons; it's normal. We would welcome
better error reporting for this scenario so it doesn't require the kind of
debugging you just did :-).

That makes sense, thank you. A timeout seems unlikely but maybe the client
is closing the connection due to a network issue. This is an extremely rare
occurrence.

While a socket is open and receiving data, recv() will either give you a
non-zero number of bytes if bytes are ready, or an EWOULDBLOCK (AKA EAGAIN) if
no bytes are ready. A result of zero bytes (the empty string) means "end of
file" - the other end has closed the socket.
So what's happening h
You're absolutely right, I meant "cancel the deferred". I don't grok server
sockets very well so maybe someone can help. But apparently, klein does a
.doRead from our server socket (getting the request from the client?). This
returns a "why" of "connection done" so that closes the connection before

Hi, I apologize this question is a little vague. I'm looking for pointers.
I have a klein route that makes an underlying deferToThread call with a
simple single thread (an IO based sync call I can't change, a boto3 sqs
write). The thread pool is simple, just a couple of threads, nothing fancy.
