Getting the Polyphony-based script to work
noteflakes opened this issue · 2 comments

The current problem with the Polyphony-based script seems to be some kind of interaction between the the fact that the connection is immediately closed by the server and how wrk handles the 200 status code with an empty response body. The script will work if you change line 13 to either of the following:
# empty response:
client.send("HTTP/1.1 204 No Content\r\nConnection: close\r\n\r\n")
# response with a body
client.send("HTTP/1.1 200 Ok\r\nConnection: close\r\nContent-Length: 5\r\n\r\nHello")Also notice that a bug in Polyphony prevents TCPSocket#send from taking a flags argument, so for now you'll need to make the #send call without the flags argument.
In addition, the io_uring backend doesn't work on Ruby 3.0. This is being addressed. (I guess you're using the libev backend, because otherwise the script would not work at all...)

Thanks for your input, fixed.
Also one time there was a segfault running libev-scheduler.rb and wrk. Could not reproduce it. Maybe you see something intersting here.
