It appears that the cause is the + fix for bug #2958179, which makes ossl_connect_common unconditionally return + from the step 2 loop when fetching from a multi handle. + + When ossl_connect_step2 has completed, it updates connssl->connecting_state + to ssl_connect_3. ossl_connect_common will then return to the caller, as a + multi handle is in use. Eventually, the client code will call + curl_multi_fdset to obtain an updated fdset to select or epoll on. For https + requests, curl_multi_fdset will cause https_getsock to be called. + https_getsock will only return a socket handle if the connecting_state is + ssl_connect_2_reading or ssl_connect_2_writing. Therefore, the client will + never obtain a valid fdset, and thus not drive the multi handle, resulting + in a hang. + + (http://curl.haxx.se/bug/view.cgi?id=3000052) + - Sebastian V reported bug #3000056 identifying a problem with redirect following. It showed that when curl followed redirects it didn't properly ignore the response body of the 30X response if that response was using |
