2016-11-25url: proxy: Use 443 as default port for https proxiesThomas Glanzmann
2016-11-25add CURLINFO_SCHEME, CURLINFO_PROTOCOL, and %{scheme}Frank Gevaerts
Adds access to the effectively used protocol/scheme to both libcurl and curl, both in string and numeric (CURLPROTO_*) form. Note that the string form will be uppercase, as it is just the internal string. As these strings are declared internally as const, and all other strings returned by curl_easy_getinfo() are de-facto const as well, string handling in getinfo.c got const-ified. Closes #1137
2016-11-24HTTPS-proxy: fixed mbedtls and polishingOkhin Vasilij
2016-11-24proxy: Support HTTPS proxy and SOCKS+HTTP(s)Alex Rousskov
* HTTPS proxies: An HTTPS proxy receives all transactions over an SSL/TLS connection. Once a secure connection with the proxy is established, the user agent uses the proxy as usual, including sending CONNECT requests to instruct the proxy to establish a [usually secure] TCP tunnel with an origin server. HTTPS proxies protect nearly all aspects of user-proxy communications as opposed to HTTP proxies that receive all requests (including CONNECT requests) in vulnerable clear text. With HTTPS proxies, it is possible to have two concurrent _nested_ SSL/TLS sessions: the "outer" one between the user agent and the proxy and the "inner" one between the user agent and the origin server (through the proxy). This change adds supports for such nested sessions as well. A secure connection with a proxy requires its own set of the usual SSL options (their actual descriptions differ and need polishing, see TODO): --proxy-cacert FILE CA certificate to verify peer against --proxy-capath DIR CA directory to verify peer against --proxy-cert CERT[:PASSWD] Client certificate file and password --proxy-cert-type TYPE Certificate file type (DER/PEM/ENG) --proxy-ciphers LIST SSL ciphers to use --proxy-crlfile FILE Get a CRL list in PEM format from the file --proxy-insecure Allow connections to proxies with bad certs --proxy-key KEY Private key file name --proxy-key-type TYPE Private key file type (DER/PEM/ENG) --proxy-pass PASS Pass phrase for the private key --proxy-ssl-allow-beast Allow security flaw to improve interop --proxy-sslv2 Use SSLv2 --proxy-sslv3 Use SSLv3 --proxy-tlsv1 Use TLSv1 --proxy-tlsuser USER TLS username --proxy-tlspassword STRING TLS password --proxy-tlsauthtype STRING TLS authentication type (default SRP) All --proxy-foo options are independent from their --foo counterparts, except --proxy-crlfile which defaults to --crlfile and --proxy-capath which defaults to --capath. Curl now also supports %{proxy_ssl_verify_result} --write-out variable, similar to the existing %{ssl_verify_result} variable. Supported backends: OpenSSL, GnuTLS, and NSS. * A SOCKS proxy + HTTP/HTTPS proxy combination: If both --socks* and --proxy options are given, Curl first connects to the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS proxy. TODO: Update documentation for the new APIs and --proxy-* options. Look for "Added in 7.XXX" marks.

2016-09-18CURLOPT_PINNEDPUBLICKEY.3: fix the AVAILABILITY formattingJay Satiro
2016-09-04speed caps: not based on average speeds anymoreOlivier Brunel
Speed limits (from CURLOPT_MAX_RECV_SPEED_LARGE & CURLOPT_MAX_SEND_SPEED_LARGE) were applied simply by comparing limits with the cumulative average speed of the entire transfer; While this might work at times with good/constant connections, in other cases it can result to the limits simply being "ignored" for more than "short bursts" (as told in man page). Consider a download that goes on much slower than the limit for some time (because bandwidth is used elsewhere, server is slow, whatever the reason), then once things get better, curl would simply ignore the limit up until the average speed (since the beginning of the transfer) reached the limit. This could prove the limit useless to effectively avoid using the entire bandwidth (at least for quite some time). So instead, we now use a "moving starting point" as reference, and every time at least as much as the limit as been transferred, we can reset this starting point to the current position. This gets a good limiting effect that applies to the "current speed" with instant reactivity (in case of sudden speed burst). Closes #971

2016-08-05CURLOPT_TCP_NODELAY: now enabled by defaultDaniel Stenberg
After a few wasted hours hunting down the reason for slowness during a TLS handshake that turned out to be because of TCP_NODELAY not being set, I think we have enough motivation to toggle the default for this option. We now enable TCP_NODELAY by default and allow applications to switch it off. This also makes --tcp-nodelay unnecessary, but --no-tcp-nodelay can be used to disable it.

2016-06-11CURLOPT_POSTFIELDS.3: Clarify what happens when set emptyJay Satiro
When CURLOPT_POSTFIELDS is set to an empty string libcurl will send a zero-byte POST. Prior to this change it was documented as sending data from the read callback. This also changes the wording of what happens when empty or NULL so that it's hopefully easier to understand for people whose primary language isn't English.
