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. [1]: https://github.com/curl/curl/commit/17c5d05 Bug: https://github.com/curl/curl/issues/3570 Bug: https://github.com/curl/curl/issues/3832 Closes https://github.com/curl/curl/pull/3853

Fixes #3813 Closes #3815

As previously planned and documented in DEPRECATE.md, all pipelining code is removed. Closes #3651
2019-03-14Negotiate: fix for HTTP POST with NegotiateDominik Hölzl
* Adjusted unit tests 2056, 2057 * do not generally close connections with CURLAUTH_NEGOTIATE after every request * moved negotiatedata from UrlState to connectdata * Added stream rewind logic for CURLAUTH_NEGOTIATE * introduced negotiatedata::GSS_AUTHDONE and negotiatedata::GSS_AUTHSUCC * Consider authproblem state for CURLAUTH_NEGOTIATE * Consider reuse_forbid for CURLAUTH_NEGOTIATE * moved and adjusted negotiate authentication state handling from output_auth_headers into Curl_output_negotiate * Curl_output_negotiate: ensure auth done is always set * Curl_output_negotiate: Set auth done also if result code is GSS_S_CONTINUE_NEEDED/SEC_I_CONTINUE_NEEDED as this result code may also indicate the last challenge request (only works with disabled Expect: 100-continue and CURLOPT_KEEP_SENDING_ON_ERROR -> 1) * Consider "Persistent-Auth" header, detect if not present; Reset/Cleanup negotiate after authentication if no persistent authentication * apply changes introduced with #2546 for negotiate rewind logic Fixes #1261 Closes #1975
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
2019-03-03alt-svc: add test 355 and 356 to verify with command line curlDaniel Stenberg
2019-03-03alt-svc: the libcurl bitsDaniel Stenberg
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
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. Reported-by: d912e3 on github Fixes #3578 Closes #3579
2019-02-10cleanup: make local functions staticDaniel Stenberg

2019-01-09cookies: skip custom cookies when redirecting cross-siteKatsuhiko YOSHIDA
Closes #3417
2019-01-07Revert "http_negotiate: do not close connection until negotiation is completed"Daniel Stenberg
This reverts commit 07ebaf837843124ee670e5b8c218b80b92e06e47. This also reopens PR #3275 which brought the change now reverted. Fixes #3384 Closes #3439
2018-12-21http: added options for allowing HTTP/0.9 responsesDaniel Stenberg
Added CURLOPT_HTTP09_ALLOWED and --http0.9 for this purpose. For now, both the tool and library allow HTTP/0.9 by default. docs/DEPRECATE.md lays out the plan for when to reverse that default: 6 months after the 7.64.0 release. The options are added already now so that applications/scripts can start using them already now. Fixes #2873 Closes #3383
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
2018-12-13cookies: leave secure cookies aloneDaniel Gustafsson
Only allow secure origins to be able to write cookies with the 'secure' flag set. This reduces the risk of non-secure origins to influence the state of secure origins. This implements IETF Internet-Draft draft-ietf-httpbis-cookie-alone-01 which updates RFC6265. Closes #2956 Reviewed-by: Daniel Stenberg <daniel@haxx.se>
2018-12-11http: fix HTTP auth to include query in URIJay Satiro
- Include query in the path passed to generate HTTP auth. Recent changes to use the URL API internally (46e1640, 7.62.0) inadvertently broke authentication URIs by omitting the query. Fixes https://github.com/curl/curl/issues/3353 Closes #3356
2018-12-11http: don't set CURLINFO_CONDITION_UNMET for http status code 204Michael Kaufmann
The http status code 204 (No Content) should not change the "condition unmet" flag. Only the http status code 304 (Not Modified) should do this. Closes #359
2018-12-07NTLM: force the connection to HTTP/1.1Johannes Schindelin
Since v7.62.0, cURL tries to use HTTP/2 whenever the server announces the capability. However, NTLM authentication only works with HTTP/1.1, and will likely remain in that boat (for details, see https://docs.microsoft.com/en-us/iis/get-started/whats-new-in-iis-10/http2-on-iis#when-is-http2-not-supported). When we just found out that we want to use NTLM, and when the current connection runs in HTTP/2 mode, let's force the connection to be closed and to be re-opened using HTTP/1.1. Fixes https://github.com/curl/curl/issues/3341. Closes #3345 Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
2018-11-23snprintf: renamed and we now only use msnprintf()Daniel Stenberg
The function does not return the same value as snprintf() normally does, so readers may be mislead into thinking the code works differently than it actually does. A different function name makes this easier to detect. Reported-by: Tomas Hoger Assisted-by: Daniel Gustafsson Fixes #3296 Closes #3297

2018-08-13http: fix for tiny "HTTP/0.9" responseDaniel Stenberg
Deal with tiny "HTTP/0.9" (header-less) responses by checking the status-line early, even before a full "HTTP/" is received to allow detecting 0.9 properly. Test 1266 and 1267 added to verify. Fixes #2420 Closes #2872

2018-07-24auth: pick Bearer authentication whenever a token is availableJohannes Schindelin
So far, the code tries to pick an authentication method only if user/password credentials are available, which is not the case for Bearer authentictation... Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Closes #2754
2018-07-24auth: only ever pick CURLAUTH_BEARER if we *have* a Bearer tokenJohannes Schindelin
The Bearer authentication was added to cURL 7.61.0, but there is a problem: if CURLAUTH_ANY is selected, and the server supports multiple authentication methods including the Bearer method, we strongly prefer that latter method (only CURLAUTH_NEGOTIATE beats it), and if the Bearer authentication fails, we will never even try to attempt any other method. This is particularly unfortunate when we already know that we do not have any Bearer token to work with. Such a scenario happens e.g. when using Git to push to Visual Studio Team Services (which supports Basic and Bearer authentication among other methods) and specifying the Personal Access Token directly in the URL (this aproach is frequently taken by automated builds). Let's make sure that we have a Bearer token to work with before we select the Bearer authentication among the available authentication methods.
