2019-07-14http: allow overriding timecond with custom headerPeter Simonyi
With CURLOPT_TIMECONDITION set, a header is automatically added (e.g. If-Modified-Since). Allow this to be replaced or suppressed with CURLOPT_HTTPHEADER. Fixes #4103 Closes #4109
2019-07-10headers: Remove no longer exported functionsDaniel Gustafsson
There were a leftover few prototypes of Curl_ functions that we used to export but no longer do, this removes those prototypes and cleans up any comments still referring to them. Curl_write32_le(), Curl_strcpy_url(), Curl_strlen_url(), Curl_up_free() Curl_concat_url(), Curl_detach_connnection(), Curl_http_setup_conn() were made static in 05b100aee247bb9bec8e9a1b0166496aa4248d1c. Curl_http_perhapsrewind() made static in 574aecee208f79d391f10d57520b3. For the remainder, I didn't trawl the Git logs hard enough to capture their exact time of deletion, but they were all gone: Curl_splayprint(), Curl_http2_send_request(), Curl_global_host_cache_dtor(), Curl_scan_cache_used(), Curl_hostcache_destroy(), Curl_second_connect(), Curl_http_auth_stage() and Curl_close_connections(). Closes #4096 Reviewed-by: Daniel Stenberg <daniel@haxx.se>
2019-03-01urldata: simplify bytecountersDaniel Stenberg
- no need to have them protocol specific - no need to set pointers to them with the Curl_setup_transfer() call - make Curl_setup_transfer() operate on a transfer pointer, not connection - switch some counters from long to the more proper curl_off_t type Closes #3627
2018-12-14http: Implement trailing headers for chunked transfersAyoub Boudhar
This adds the CURLOPT_TRAILERDATA and CURLOPT_TRAILERFUNCTION options that allow a callback based approach to sending trailing headers with chunked transfers. The test server (sws) was updated to take into account the detection of the end of transfer in the case of trailing headers presence. Test 1591 checks that trailing headers can be sent using libcurl. Closes #3350

2016-04-11http2: Ensure that http2_handle_stream_close is calledTatsuhiro Tsujikawa
This commit ensures that streams which was closed in on_stream_close callback gets passed to http2_handle_stream_close. Previously, this might not happen. To achieve this, we increment drain property to forcibly call recv function for that stream. To more accurately check that we have no pending event before shutting down HTTP/2 session, we sum up drain property into http_conn.drain_total. We only shutdown session if that value is 0. With this commit, when stream was closed before reading response header fields, error code CURLE_HTTP2_STREAM is returned even if HTTP/2 level error is NO_ERROR. This signals the upper layer that stream was closed by error just like TCP connection close in HTTP/1. Ref: https://github.com/curl/curl/issues/659 Ref: https://github.com/curl/curl/pull/663

2015-12-15http2: Support trailer fieldsTatsuhiro Tsujikawa
This commit adds trailer support in HTTP/2. In HTTP/1.1, chunked encoding must be used to send trialer fields. HTTP/2 deprecated any trandfer-encoding, including chunked. But trailer fields are now always available. Since trailer fields are relatively rare these days (gRPC uses them extensively though), allocating buffer for trailer fields is done when we detect that HEADERS frame containing trailer fields is started. We use Curl_add_buffer_* functions to buffer all trailers, just like we do for regular header fields. And then deliver them when stream is closed. We have to be careful here so that all data are delivered to upper layer before sending trailers to the application. We can deliver trailer field one by one using NGHTTP2_ERR_PAUSE mechanism, but current method is far more simple. Another possibility is use chunked encoding internally for HTTP/2 traffic. I have not tested it, but it could add another overhead. Closes #564
2015-08-11http2: discard frames with no SessionHandleAnders Bakken
Return 0 instead of NGHTTP2_ERR_CALLBACK_FAILURE if we can't locate the SessionHandle. Apparently mod_h2 will sometimes send a frame for a stream_id we're finished with. Use nghttp2_session_get_stream_user_data and nghttp2_session_set_stream_user_data to identify SessionHandles instead of a hash. Closes #372

2015-05-18http2: Read data left in connection buffer after pauseTatsuhiro Tsujikawa
Previously when we do pause because of out of buffer, we just throw away unread data in connection buffer. This just broke protocol framing, and I saw occasional FRAME_SIZE_ERROR. This commit fix this issue by remembering how much data read, and in the next iteration, we process remaining data.

... from the connection struct. The stream one being the 'struct HTTP' which is kept in the SessionHandle struct (easy handle). lookup streams for incoming frames in the stream hash, hashing is based on the stream id and we get the SessionHandle for the incoming stream that way.

2015-02-27http2: Return error if stream was closed with other than NO_ERRORTatsuhiro Tsujikawa
Previously, we just ignored error code passed to on_stream_close_callback and just return 0 (success) after stream closure even if stream was reset with error. This patch records error code in on_stream_close_callback, and return -1 and use CURLE_HTTP2 error code on abnormal stream closure.
2014-08-02HTTP2: Support expect: 100-continueTatsuhiro Tsujikawa
"Expect: 100-continue", which was once deprecated in HTTP/2, is now resurrected in HTTP/2 draft 14. This change adds its support to HTTP/2 code. This change also includes stricter header field checking.

2014-02-17http2: Support HTTP POST/PUTTatsuhiro Tsujikawa
This patch enables HTTP POST/PUT in HTTP2. We disabled Expect header field and chunked transfer encoding since HTTP2 forbids them. In HTTP1, Curl sends small upload data with request headers, but HTTP2 requires upload data must be in DATA frame separately. So we added some conditionals to achieve this.

2014-02-04HTTP2: add layer between existing http and socket(TLS) layerTatsuhiro Tsujikawa
This patch chooses different approach to integrate HTTP2 into HTTP curl stack. The idea is that we insert HTTP2 layer between HTTP code and socket(TLS) layer. When HTTP2 is initialized (either in NPN or Upgrade), we replace the Curl_recv/Curl_send callbacks with HTTP2's, but keep the original callbacks in http_conn struct. When sending serialized data by nghttp2, we use original Curl_send callback. Likewise, when reading data from network, we use original Curl_recv callback. In this way we can treat both TLS and non-TLS connections. With this patch, one can transfer contents from https://twitter.com and from nghttp2 test server in plain HTTP as well. The code still has rough edges. The notable one is I could not figure out how to call nghttp2_session_send() when underlying socket is writable.

2013-11-03http: Post base64 decoding tidy upSteve Holme
Renamed copy_header_value() to Curl_copy_header_value() as this function is now non static. Simplified proxy flag in Curl_http_input_auth() when calling sub-functions. Removed unnecessary white space removal when using negotiate as it had been missed in commit cdccb422671aeb.
