2018-12-22disconnect: separate connections and easy handles betterDaniel Stenberg
Do not assume/store assocation between a given easy handle and the connection if it can be avoided. Long-term, the 'conn->data' pointer should probably be removed as it is a little too error-prone. Still used very widely though. Reported-by: masbug on github Fixes #3391 Closes #3400
2018-12-22libssh: free sftp_canonicalize_path() data correctlyDaniel Stenberg

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

2018-12-19cookies: extend domain checks to non psl buildsDaniel Gustafsson
Ensure to perform the checks we have to enforce a sane domain in the cookie request. The check for non-PSL enabled builds is quite basic but it's better than nothing. Closes #2964 Reviewed-by: Daniel Stenberg <daniel@haxx.se>
2018-12-19smb: fix incorrect path in request if connection reusedMatus Uzak
Follow-up to 09e401e01bf9. If connection gets reused, then data member will be copied, but not the proto member. As a result, in smb_do(), path has been set from the original proto.share data. Closes #3388

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

2018-12-13gopher: always include the entire gopher-path in requestLeonardo Taccari
After the migration to URL API all octets in the selector after the first `?' were interpreted as query and accidentally discarded and not passed to the server. Add a gopherpath to always concatenate possible path and query URL pieces. Fixes #3369 Closes #3370
2018-12-13urlapi: distinguish possibly empty queryLeonardo Taccari
If just a `?' to indicate the query is passed always store a zero length query instead of having a NULL query. This permits to distinguish URL with trailing `?'. Fixes #3369 Closes #3370
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>
2018-12-12urlapi: Fix port parsing of eol colonDaniel Gustafsson
A URL with a single colon without a portnumber should use the default port, discarding the colon. Fix, add a testcase and also do little bit of comment wordsmithing. Closes #3365 Reviewed-by: Daniel Stenberg <daniel@haxx.se>

2018-12-11multi: convert two timeout variables to timediff_tDaniel Stenberg
The time_t type is unsigned on some systems and these variables are used to hold return values from functions that return timediff_t already. timediff_t is always a signed type. Closes #3363
2018-12-11tests: add urlapi unittestDaniel Gustafsson
This adds a new unittest intended to cover the internal functions in the urlapi code, starting with parse_port().

An IPv6 URL which contains a zone index includes a '%%25<zode id>' string before the ending ']' bracket. The parsing logic wasn't set up to cope with the zone index however, resulting in a malformed url error being returned. Fix by breaking the parsing into two stages to correctly handle the zone index.

All resources defined in lib/libcurl.rc and curl.rc are language neutral. winbuild/MakefileBuild.vc ALWAYS defines the macro DEBUGBUILD, so the ifdef's in line 33 of lib/libcurl.rc and src/curl.rc are wrong.

2018-12-08Upon HTTP_1_1_REQUIRED, retry the request with HTTP/1.1Johannes Schindelin
This is a companion patch to cbea2fd2c (NTLM: force the connection to HTTP/1.1, 2018-12-06): with NTLM, we can switch to HTTP/1.1 preemptively. However, with other (Negotiate) authentication it is not clear to this developer whether there is a way to make it work with HTTP/2, so let's try HTTP/2 first and fall back in case we encounter the error HTTP_1_1_REQUIRED. Note: we will still keep the NTLM workaround, as it avoids an extra round trip. Daniel Stenberg helped a lot with this patch, in particular by suggesting to introduce the Curl_h2_http_1_1_error() function.

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>
2018-12-07curl_global_sslset(): id == -1 is not necessarily an errorJohannes Schindelin
It is allowed to call that function with id set to -1, specifying the backend by the name instead. We should imitate what is done further down in that function to allow for that. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Closes #3346

2018-12-05nss: Fall back to latest supported SSL versionPaul Howarth
NSS may be built without support for the latest SSL/TLS versions, leading to "SSL version range is not valid" errors when the library code supports a recent version (e.g. TLS v1.3) but it has explicitly been disabled. This change adjusts the maximum SSL version requested by libcurl to be the maximum supported version at runtime, as long as that version is at least as high as the minimum version required by libcurl. Fixes #3261
2018-12-03checksrc: add COPYRIGHTYEAR checkDaniel Gustafsson
Forgetting to bump the year in the copyright clause when hacking has been quite common among curl developers, but a traditional checksrc check isn't a good fit as it would penalize anyone hacking on January 1st (among other things). This adds a more selective COPYRIGHTYEAR check which intends to only cover the currently hacked on changeset. The check for updated copyright year is currently not enforced on all files but only on files edited and/or committed locally. This is due to the amount of files which aren't updated with their correct copyright year at the time of their respective commit. To further avoid running this expensive check for every developer, it adds a new local override mode for checksrc where a .checksrc file can be used to turn on extended warnings locally.

curl_multi_wait() was erroneously used from within curl_easy_perform().

2018-11-21openssl: support session resume with TLS 1.3Michael Kaufmann
Session resumption information is not available immediately after a TLS 1.3 handshake. The client must wait until the server has sent a session ticket. Use OpenSSL's "new session" callback to get the session information and put it into curl's session cache. For TLS 1.3 sessions, this callback will be invoked after the server has sent a session ticket. The "new session" callback is invoked only if OpenSSL's session cache is enabled, so enable it and use the "external storage" mode which lets curl manage the contents of the session cache. A pointer to the connection data and the sockindex are now saved as "SSL extra data" to make them available to the callback. This approach also works for old SSL/TLS versions and old OpenSSL versions. Reviewed-by: Daniel Stenberg <daniel@haxx.se> Fixes #3202 Closes #3271

2018-11-20ares: remove fd from multi fd set when ares is about to close the fdRomain Fliedel
When using c-ares for asyn dns, the dns socket fd was silently closed by c-ares without curl being aware. curl would then 'realize' the fd has been removed at next call of Curl_resolver_getsock, and only then notify the CURLMOPT_SOCKETFUNCTION to remove fd from its poll set with CURL_POLL_REMOVE. At this point the fd is already closed. By using ares socket state callback (ARES_OPT_SOCK_STATE_CB), this patch allows curl to be notified that the fd is not longer needed for neither for write nor read. At this point by calling Curl_multi_closed we are able to notify multi with CURL_POLL_REMOVE before the fd is actually closed by ares. In asyn-ares.c Curl_resolver_duphandle we can't use ares_dup anymore since it does not allow passing a different sock_state_cb_data Closes #3238
