The whole point of curl_multi_select is to block until either there's some activity on the socket, or the timeout is reached. The curl_multi_select() call now returns immediately (with -1), without waiting for the timeout, in all our use cases too, making it useless. Why was the behaviour changed in the first place? Is it possible to revert? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
