- Curl_write_plain/Curl_read_plain have been eliminated. Last code use now uses Curl_conn_send/recv so that requests use conn->send/revc callbacks which defaults to cfilters use. - Curl_recv_plain/Curl_send_plain have been internalized in cf-socket.c. - USE_RECV_BEFORE_SEND_WORKAROUND (active on Windows) has been moved into cf-socket.c. The pre_recv buffer is held at the socket filter context. `postponed_data` structures have been removed from `connectdata`. - the hanger in HTTP/2 request handling was a result of read buffering on all sends and the multi handling is not prepared for this. The following happens: - multi preforms on a HTTP/2 easy handle - h2 reads and processes data - this leads to a send of h2 data - which receives and buffers before the send - h2 returns - multi selects on the socket, but no data arrives (its in the buffer already) the workaround now receives data in a loop as long as there is something in the buffer. The real fix would be for multi to change, so that `data_pending` is evaluated before deciding to wait on the socket. io_buffer, optional, in cf-socket.c, http/2 sets state.drain if lower filter have pending data. This io_buffer is only available/used when the -DUSE_RECV_BEFORE_SEND_WORKAROUND is active, e.g. on Windows configurations. It also maintains the original checks on protocol handler being HTTP and conn->send/recv not being replaced. The HTTP/2 (nghttp2) cfilter now sets data->state.drain when it finds out that the "lower" filter chain has still pending data at the end of its IO operation. This prevents the processing from becoming stalled. Closes #10280 |
