Some systems poll function sets POLLHUP in revents without setting POLLIN, and sets POLLERR without setting POLLIN and POLLOUT. In some libcurl code execution paths this could trigger busy wait loops with high CPU usage until a timeout condition aborted the loop. The reverted patch addressed the above issue for a very specific case, when awaiting c-ares to resolve. A libcurl-wide fix for Curl_poll now superceeds this one. Guenter Knauf (11 Sep 2009) - Joshua Kwan provided a patch to pass POLLERR / POLLHUP back to c-ares. This fixes a loop problem with high CPU usage. Loading Loading
