Andy Green switched off that 20 (yes, twenty!) months ago [1]. It was always a hack, few people used it and generated way too many messages.

Indeed, Andy provides at least two options for that: libev (full featured and high-performance event loop) and libuv (which is an asynchronous library, also used for Node.js). Meaning both are common and tested. > I'm rewriting to use a different library so I don't have to deal with > that kind of breakage again, but in the meantime I don't want my > users to suffer - without this change the websockets feature is > unusable. But as I know, websockets is a second class citizen in mosquitto [2]. My question is what functional difference will be in mosquitto without the websocket external poll support? I'm not sure it will not hit other websocket users. You had two years (maybe more) to switch to a better alternative of the hacky external poll support but only now realize your code is not complete without it. :( Regards, Laszlo/GCS [1] https://libwebsockets.org/git/libwebsockets/commit/CMakeLists.txt?id=d3021980194991d175388115a65a4265bd155f36 [2] https://sources.debian.org/src/mosquitto/2.0.7-3/src/loop.c/?hl=257#L257
