Hi there,
For my research project, I'm trying to change the Go runtime to use "Epolloneshot" instead of the default "Edge-Triggered" mode. Based on what I've gathered from the code, I've changed two functions in src/runtime/netpoll_epoll.go. First, I updated the netpollopen function to use the Epolloneshot flag instead of the Epollet flag. Second, I modified the netpollarm function, which isn't used in Linux, to rearm notifications for Epolloneshot. I also tweaked poll_runtime_pollWait() in src/runtime/netpoll.go to call netpollarm for Linux. Now, I'm running into an issue where HTTP tests for compiling Go are failing. Here's the error I'm seeing: "httptest.Server blocked in Close after 5 seconds, waiting for connections: *net.TCPConn 0xc000221520 127.0.0.1:51836 in state active panic: test timed out after 9m0s" I suspect that the rearming might be incorrect, causing the server to stall indefinitely. Just so you know, I'm using Ubuntu 22.04 and Go 1.18.10. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
