      lib1500: remove bad check · 87cf677e
      Daniel Stenberg authored
      After curl_multi_wait() returns, this test checked that we got exactly
      one file descriptor told to read from, but we cannot be sure that is
      true. curl_multi_wait() will sometimes return earlier without any file
      descriptor to handle, just just because it is a suitable time to call
      *perform().
      
      This problem showed up with commit 29bf0598.

      ossl_recv: SSL_read() returning 0 is an error too · 520833cb

      SSL_read can return 0 for "not successful", according to the open SSL
      documentation: http://www.openssl.org/docs/ssl/SSL_read.html

      ossl_send: SSL_write() returning 0 is an error too · e58d9c87
      Mike Giancola authored
      We found that in specific cases if the connection is abruptly closed,
      the underlying socket is listed in a close_wait state. We continue to
      call the curl_multi_perform, curl_mutli_fdset etc. None of these APIs
      report the socket closed / connection finished.  Since we have cases
      where the multi connection is only used once, this can pose a problem
      for us. I've read that if another connection was to come in, curl would
      see the socket as bad and attempt to close it at that time -
      unfortunately, this does not work for us.
      
      I found that in specific situations, if SSL_write returns 0, curl did
      not recognize the socket as closed (or errored out) and did not report
      it to the application. I believe we need to change the code slightly, to
      check if ssl_write returns 0. If so, treat it as an error - the same as
      a negative return code.
      
      For OpenSSL - the ssl_write documentation is here:
