[Twisted-Python] twisted.web HTTPS client certificate

I am trying to work out how to retrieve on the server a X.509 certificate presented by the HTTPS client.  This code tries to tell me the transport has no peer certificate. same error when I use wget as a client so I think my problem is in the server code. I'm using self-signed certificates A

[Twisted-Python] reactor for Linux io_uring

In investigating async file I/O I came across this. In a nutshell it's the new epoll() It's marginally more efficient although this is only apparent at very high loads. What's more interesting is that io_uring accepts files as well as network/pipe handles: avoiding the need for threads. Here

Re: [Twisted-Python] Plan/Goal for GitHub Sponsors

I think having a project coordinator as   a *first* priority isn't a good idea (not saying it isn't down the track) Currently there's little to coordinate as the core team aren't active in planning or review. can the team be expanded ? (I'm not angling for a role myself) Ian On 4/01/2021 11

Re: [Twisted-Python] Participating to GitHub Sponsors

No objection, but any plans for the money? I'd ask for more reviewers, I'd like to contribute more to twisted but there's little point without access to code review in a reasonable timeframe. On 16/12/2020 11:56 am, Adi Roiban wrote: Hi, Does anyone have anything against applying so that Twis

[Twisted-Python] composition VS. inheritance

In smb I have a SMBPacketReceiver that inherits from t.i.p.Protocol, it breaks the incoming TCP stream into logical packets (the analogue of LineReceiver in line-based protocols). I then subclass SMBPacketReceiver to SMBProtocol which does a lot of the "heavy lifting" analyzing incoming packet

[Twisted-Python] new code: 3.5 or 3.6?

I've followed the discussion re 3.6 and type annotations, but evidently not closely enough when writing new code for twisted today, can we use 3.6 features or is 3.5 still required? (it's actually a library feature enum.IntFlag I'm curious about, not type annotations) Ian __
