2020-02-26http: added 417 response treatmentDaniel Stenberg
When doing a request with a body + Expect: 100-continue and the server responds with a 417, the same request will be retried immediately without the Expect: header. Added test 357 to verify. Also added a control instruction to tell the sws test server to not read the request body if Expect: is present, which the new test 357 uses. Reported-by: bramus on github Fixes #4949 Closes #4964

2019-12-09conncache: fix multi-thread use of shared connection cacheDaniel Stenberg
It could accidentally let the connection get used by more than one thread, leading to double-free and more. Reported-by: Christopher Reid Fixes #4544 Closes #4557
2019-11-29parsedate: offer a getdate_capped() alternativeDaniel Stenberg
... and use internally. This function will return TIME_T_MAX instead of failure if the parsed data is found to be larger than what can be represented. TIME_T_MAX being the largest value curl can represent. Reviewed-by: Daniel Gustafsson Reported-by: JanB on github Fixes #4152 Closes #4651

Fixes #4525 Closes #4603
2019-09-28cookies: using a share with cookies shouldn't enable the cookie engineDaniel Stenberg
The 'share object' only sets the storage area for cookies. The "cookie engine" still needs to be enabled or activated using the normal cookie options. This caused the curl command line tool to accidentally use cookies without having been told to, since curl switched to using shared cookies in 7.66.0. Test 1166 verifies Updated test 506 Fixes #4429 Closes #4434

2019-08-20http: remove chunked-encoding and expect header use for HTTP/3Daniel Stenberg
2019-08-16http: fix use of credentials from URL when using HTTP proxyDaniel Stenberg
When a username and password are provided in the URL, they were wrongly removed from the stored URL so that subsequent uses of the same URL wouldn't find the crendentials. This made doing HTTP auth with multiple connections (like Digest) mishave. Regression from 46e164069d1a5230 (7.62.0) Test case 335 added to verify. Reported-by: Mike Crowe Fixes #4228 Closes #4229

2019-08-08http3: fix the HTTP/3 in the request, make alt-svc set right versionsDaniel Stenberg
Closes #4200
2019-08-08alt-svc: send Alt-Used: in redirected requestsDaniel Stenberg
RFC 7838 section 5: When using an alternative service, clients SHOULD include an Alt-Used header field in all requests. Removed CURLALTSVC_ALTUSED again (feature is still EXPERIMENTAL thus this is deemed ok). You can disable sending this header just like you disable any other HTTP header in libcurl. Closes #4199
2019-08-08CURLOPT_HTTP_VERSION: seting this to 3 forces HTTP/3 use directlyDaniel Stenberg
Even though it cannot fall-back to a lower HTTP version automatically. The safer way to upgrade remains via CURLOPT_ALTSVC. CURLOPT_H3 no longer has any bits that do anything and might be removed before we remove the experimental label. Updated the curl tool accordingly to use "--http3". Closes #4197
2019-08-07CURLINFO_RETRY_AFTER: parse the Retry-After header valueDaniel Stenberg
This is only the libcurl part that provides the information. There's no user of the parsed value. This change includes three new tests for the parser. Ref: #3794
2019-08-06quiche: first working HTTP/3 requestDaniel Stenberg
- enable debug log - fix use of quiche API - use download buffer - separate header/body Closes #4193
2019-07-30cleanup: remove the 'numsocks' argument used in many placesDaniel Stenberg
It was used (intended) to pass in the size of the 'socks' array that is also passed to these functions, but was rarely actually checked/used and the array is defined to a fixed size of MAX_SOCKSPEREASYHANDLE entries that should be used instead. Closes #4169
2019-07-29HTTP: use chunked Transfer-Encoding for HTTP_POST if size unknownBalazs Kovacsics
If using the read callback for HTTP_POST, and POSTFIELDSIZE is not set, automatically add a Transfer-Encoding: chunked header, same as it is already done for HTTP_PUT, HTTP_POST_FORM and HTTP_POST_MIME. Update test 1514 according to the new behaviour. Closes #4138
2019-07-21HTTP3: initial (experimental) supportDaniel Stenberg
USe configure --with-ngtcp2 or --with-quiche Using either option will enable a HTTP3 build. Co-authored-by: Alessandro Ghedini <alessandro@ghedini.me> Closes #3500
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>
2019-06-24http: clarify header buffer size calculationDaniel Gustafsson
The header buffer size calculation can from static analysis seem to overlow as it performs an addition between two size_t variables and stores the result in a size_t variable. Overflow is however guarded against elsewhere since the input to the addition is regulated by the maximum read buffer size. Clarify this with a comment since the question was asked.

2019-06-24http2: call done_sending on end of uploadDaniel Stenberg

2019-06-02http: don't parse body-related headers bodyless responsesMichael Kaufmann
Responses with status codes 1xx, 204 or 304 don't have a response body. For these, don't parse these headers: - Content-Encoding - Content-Length - Content-Range - Last-Modified - Transfer-Encoding This change ensures that HTTP/2 upgrades work even if a "Content-Length: 0" or a "Transfer-Encoding: chunked" header is present.

2019-05-08http: Ignore HTTP/2 prior knowledge setting for HTTP proxiesJay Satiro
- Do not switch to HTTP/2 for an HTTP proxy that is not tunnelling to the destination host. We already do something similar for HTTPS proxies by not sending h2. [1] Prior to this change setting CURL_HTTP_VERSION_2_PRIOR_KNOWLEDGE would incorrectly use HTTP/2 to talk to the proxy, which is not something we support (yet?). Also it's debatable whether or not that setting should apply to HTTP/2 proxies.

2019-03-13http: send payload when (proxy) authentication is doneMarc Schlatter
The check that prevents payload from sending in case of authentication doesn't check properly if the authentication is done or not. They're cases where the proxy respond "200 OK" before sending authentication challenge. This change takes care of that. Fixes #2431 Closes #3669

2019-02-28http: set state.infilesize when sending formpostsDaniel Stenberg
Without it set, we would unwillingly triger the "HTTP error before end of send, stop sending" condition even if the entire POST body had been sent (since it wouldn't know the expected size) which would unnecessarily log that message and close the connection when it didn't have to. Reported-by: Matt McClure Bug: https://curl.haxx.se/mail/archive-2019-02/0023.html Closes #3624
2019-02-27urldata: convert bools to bitfields and move to endDaniel Stenberg
This allows the compiler to pack and align the structs better in memory. For a rather feature-complete build on x86_64 Linux, gcc 8.1.2 makes the Curl_easy struct 4.9% smaller. From 6312 bytes to 6000. Removed an unused struct field. No functionality changes. Closes #3610
2019-02-19http: make adding a blank header thread-safeDaniel Stenberg
Previously the function would edit the provided header in-place when a semicolon is used to signify an empty header. This made it impossible to use the same set of custom headers in multiple threads simultaneously. This approach now makes a local copy when it needs to edit the string.
