2019-01-13extract_if_dead: use a known working transfer when checking connectionsDaniel Stenberg
Make sure that this function sets a proper "live" transfer for the connection before calling the protocol-specific connection check function, and then clear it again afterward as a non-used connection has no current transfer.

2019-01-11urldata: rename easy_conn to just connDaniel Stenberg
We use "conn" everywhere to be a pointer to the connection. Introduces two functions that "attaches" and "detaches" the connection to and from the transfer. Going forward, we should favour using "data->conn" (since a transfer always only has a single connection or none at all) to "conn->data" (since a connection can have none, one or many transfers associated with it and updating conn->data to be correct is error prone and a frequent reason for internal issues). Closes #3442

2019-01-10multi: multiplexing improvementsDaniel Stenberg
Fixes #3436 Closes #3448 Problem 1 After LOTS of scratching my head, I eventually realized that even when doing 10 uploads in parallel, sometimes the socket callback to the application that tells it what to wait for on the socket, looked like it would reflect the status of just the single transfer that just changed state. Digging into the code revealed that this was indeed the truth. When multiple transfers are using the same connection, the application did not correctly get the *combined* flags for all transfers which then could make it switch to READ (only) when in fact most transfers wanted to get told when the socket was WRITEABLE. Problem 1b A separate but related regression had also been introduced by me when I cleared connection/transfer association better a while ago, as now the logic couldn't find the connection and see if that was marked as used by more transfers and then it would also prematurely remove the socket from the socket hash table even in times other transfers were still using it! Fix 1 Make sure that each socket stored in the socket hash has a "combined" action field of what to ask the application to wait for, that is potentially the ORed action of multiple parallel transfers. And remove that socket hash entry only if there are no transfers left using it. Problem 2 The socket hash entry stored an association to a single transfer using that socket - and when curl_multi_socket_action() was called to tell libcurl about activities on that specific socket only that transfer was "handled". This was WRONG, as a single socket/connection can be used by numerous parallel transfers and not necessarily a single one. Fix 2 We now store a list of handles in the socket hashtable entry and when libcurl is told there's traffic for a particular socket, it now iterates over all known transfers using that single socket.

When building with Unicode on MSVC, the compiler warns about freeing a pointer to const in Curl_unicodefree. Fix this by declaring it as non-const and casting the argument to Curl_convert_UTF8_to_tchar to non-const too, like we do in all other places. Closes https://github.com/curl/curl/pull/3435

2018-12-30urlapi: fix parsing ipv6 with zone indexDaniel Gustafsson
The previous fix for parsing IPv6 URLs with a zone index was a paddle short for URLs without an explicit port. This patch fixes that case and adds a unit test case. This bug was highlighted by issue #3408, and while it's not the full fix for the problem there it is an isolated bug that should be fixed regardless.

2018-12-27hostip: support wildcard hostsClaes Jakobsson
This adds support for wildcard hosts in CURLOPT_RESOLVE. These are try-last so any non-wildcard entry is resolved first. If specified, any host not matched by another CURLOPT_RESOLVE config will use this as fallback. Example send a.com to 10.0.0.1 and everything else to 10.0.0.2: curl --resolve *:443:10.0.0.2 --resolve a.com:443:10.0.0.1 \ https://a.com https://b.com This is probably quite similar to using: --connect-to a.com:443:10.0.0.1:443 --connect-to :443:10.0.0.2:443 Closes #3406 Reviewed-by: Daniel Stenberg <daniel@haxx.se>

2018-12-23timeval: Use high resolution timestamps on WindowsPavel P
- Use QueryPerformanceCounter on Windows Vista+ There is confusing info floating around that QueryPerformanceCounter can leap etc, which might have been true long time ago, but no longer the case nowadays (perhaps starting from WinXP?). Also, boost and std::chrono::steady_clock use QueryPerformanceCounter in a similar way. Prior to this change GetTickCount or GetTickCount64 was used, which has lower resolution. That is still the case for <= XP. Fixes https://github.com/curl/curl/issues/3309 Closes https://github.com/curl/curl/pull/3318

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.
