2014-01-15win32: Fixed use of deprecated function 'GetVersionInfoEx' for VC12Steve Holme
Starting with Visual Studio 2013 (VC12) and Windows 8.1 the GetVersionInfoEx() function has been marked as deprecated and it's return value atered. Updated connect.c and curl_sspi.c to use VerifyVersionInfo() where possible, which has been available since Windows 2000.
2014-01-12multi: remove MULTI_TIMEOUT_INACCURACYDaniel Stenberg
With the recently added timeout "reminder" functionality, there's no reason left for us to execute timeout code before the time is ripe. Simplifies the handling too. This will make the *TIMEOUT and *CONNECTTIMEOUT options more accurate again, which probably is most important when the *_MS versions are used. In multi_socket, make sure to update 'now' after having handled activity on a socket.

2013-12-28connect: Try all addresses in first connection attemptBjörn Stenberg
Fixes a bug when all addresses in the first family fail immediately, due to "Network unreachable" for example, curl would hang and never try the next address family. Iterate through all address families when to trying establish the first connection attempt. Bug: http://curl.haxx.se/bug/view.cgi?id=1315 Reported-by: Michal Górny and Anthony G. Basile

2013-11-27connect: Try next ip directly after immediate connect failBjörn Stenberg
This fixes a rare Happy Eyeballs bug where if the first IP family runs out of addresses before the second-family-timer fires, and the second IP family's first connect fails immediately, no further IPs of the second family are attempted.
2013-11-17connect: Close open but unconnected socket in singleipconnect()Steve Holme
singleipconnect() could return the file descriptor of an open socket even though the function returned a CURLE_COULDNT_CONNECT error code from commit ed1662c374361a and 02fbc26d59c591. This could cause tests 19, 704 and 1233 to fail on FreeBSD, AIX and Solaris.
2013-11-14connect: Forgot to correct line endings before push in commit ed1662c374361aSteve Holme
2013-11-14connect: Return the socket descriptor even on failBjörn Stenberg
singleipconnect() did not return the open socket descriptor on some errors, thereby sometimes causing a socket leak. This patch ensures the socket is always returned.
2013-11-10connect: Close temporary sockets in conn_free()Björn Stenberg
The temporary sockets used for Happy Eyeballs were not closed properly, if curl exited prematurely, which this patch fixes.
2013-11-04connect: Add connection delay to Happy Eyeballs.Björn Stenberg
This patch adds a 200ms delay between the first and second address family socket connection attempts. It also iterates over IP addresses in the order returned by the system, meaning most dual-stack systems will try IPv6 first. Additionally, it refactors the connect code, removing most code that handled synchronous connects. Since all sockets are now non-blocking, the logic can be made simpler.
2013-11-03connect.c: Code policing on commit 5094bb53f4a027Steve Holme
No need for a rhs condition on a bitwise compare.
2013-11-03connect: Fixed "Whut?" no server connection failuresSteve Holme
Introduced in commit 7d7df831981fee curl would loop displaying "Whut?" if it was trying to connect to an address and port that didn't have anything listening on it.
2013-10-29bugfix: Don't block waiting for socket1 connect.Björn Stenberg
This patch fixes a bug in Happy Eyeballs where curl would wait for a connect response from socket1 before checking socket2. Also, it updates error messages for failed connections, showing the ip addresses that failed rather than just the host name repeatedly. Bug: http://curl.haxx.se/mail/lib-2013-10/0236.html Reported-by: Paul Marks
2013-10-27Typo fix in trynextip().Björn Stenberg
2013-10-27Add "Happy Eyeballs" for IPv4/IPv6.Björn Stenberg
This patch invokes two socket connect()s nearly simultaneously, and the socket that is first connected "wins" and is subsequently used for the connection. The other is terminated. There is a very slight IPv4 preference, in that if both sockets connect simultaneously IPv4 is checked first and thus will win.
2013-10-26FTP: make the data connection work when going through proxyDaniel Stenberg
This is a regression since the switch to always-multi internally c43127414d89c. Test 1316 was modified since we now clearly call the Curl_client_write() function when doing the LIST transfer part and then the handler->protocol says FTP and ftpc.transfertype is 'A' which implies text converting even though that the response is initially a HTTP CONNECT response in this case.

2013-06-20multi_socket: react on socket close immediatelyDaniel Stenberg
As a remedy to the problem when a socket gets closed and a new one is opened with the same file descriptor number and as a result multi.c:singlesocket() doesn't detect the difference, the new function Curl_multi_closed() gets told when a socket is closed so that it can be removed from the socket hash. When the old one has been removed, a new socket should be detected fine by the singlesocket() on next invoke. Bug: http://curl.haxx.se/bug/view.cgi?id=1248 Reported-by: Erik Johansson
2013-05-01bindlocal: move brace out of #ifdefLars Johannesen
The code within #ifdef HAVE_SOCKADDR_IN6_SIN6_SCOPE_ID wrongly had two closing braces when it should only have one, so builds without that define would fail. Bug: http://curl.haxx.se/mail/lib-2013-05/0000.html
2013-04-08tcpkeepalive: Support CURLOPT_TCP_KEEPIDLE on OSXRobert Wruck
MacOS X doesn't have TCP_KEEPIDLE/TCP_KEEPINTVL but only a single TCP_KEEPALIVE (see http://developer.apple.com/library/mac/#DOCUMENTATION/Darwin/Reference/ManPages/man4/tcp.4.html). Here is a patch for CURLOPT_TCP_KEEPIDLE on OSX platforms.
2013-04-06connect: treat an interface bindlocal() problem as a non-fatal errorKim Vandry
I am using curl_easy_setopt(CURLOPT_INTERFACE, "if!something") to force transfers to use a particular interface but the transfer fails with CURLE_INTERFACE_FAILED, "Failed binding local connection end" if the interface I specify has no IPv6 address. The cause is as follows: The remote hostname resolves successfully and has an IPv6 address and an IPv4 address. cURL attempts to connect to the IPv6 address first. bindlocal (in lib/connect.c) fails because Curl_if2ip cannot find an IPv6 address on the interface. This is a fatal error in singleipconnect() This change will make cURL try the next IP address in the list. Also included are two changes related to IPv6 address scope: - Filter the choice of address in Curl_if2ip to only consider addresses with the same scope ID as the connection address (mismatched scope for local and remote address does not result in a working connection). - bindlocal was ignoring the scope ID of addresses returned by Curl_if2ip . Now it uses them. Bug: http://curl.haxx.se/bug/view.cgi?id=1189
2013-04-02SO_SNDBUF: don't set SNDBUF for win32 versions vista or laterDaniel Stenberg
The Microsoft knowledge-base article http://support.microsoft.com/kb/823764 describes how to use SNDBUF to overcome a performance shortcoming in winsock, but it doesn't apply to Windows Vista and later versions. If the described SNDBUF magic is applied when running on those more recent Windows versions, it seems to instead have the reversed effect in many cases and thus make libcurl perform less good on those systems. This fix thus adds a run-time version-check that does the SNDBUF magic conditionally depending if it is deemed necessary or not.

2013-01-09build: fix circular header inclusion with other packagesYang Tse
This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact.

2012-12-07Introducing a new persistent connection caching system using "bundles".Linus Nielsen Feltzing
A bundle is a list of all persistent connections to the same host. The connection cache consists of a hash of bundles, with the hostname as the key. The benefits may not be obvious, but they are two: 1) Faster search for connections to reuse, since the hash lookup only finds connections to the host in question. 2) It lays out the groundworks for an upcoming patch, which will introduce multiple HTTP pipelines. This patch also removes the awkward list of "closure handles", which were needed to send QUIT commands to the FTP server when closing a connection. Now we allocate a separate closure handle and use that one to close all connections. This has been tested in a live system for a few weeks, and of course passes the test suite.

2012-06-11connect.c/ftp.c: Fixed dereferencing pointer breakin strict-aliasingMarc Hoersken
Fixed warning: dereferencing pointer does break strict-aliasing rules by using a union instead of separate pointer variables. Internal union sockaddr_u could probably be moved to generic header. Thanks to Paul Howarth for the hint about using unions for this. Important for winbuild: Separate declaration of sockaddr_u pointer. The pointer variable *sock cannot be declared and initialized right after the union declaration. Therefore it has to be a separate statement.
2012-04-19singleipconnect: return OK even when Curl_socket() failsDaniel Stenberg
Commit 9109cdec11ee5a brought this regression (shipped since 7.24.0). The singleipconnect() function must not return an error if Curl_socket() returns an error. It should then simply return OK and pass a SOCKET_BAD back simply because that is how the user of this function expects it to work and something else is not fine.

2012-02-09add library support for tuning TCP_KEEPALIVEDave Reisner
This adds three new options to control the behavior of TCP keepalives: - CURLOPT_TCP_KEEPALIVE: enable/disable probes - CURLOPT_TCP_KEEPIDLE: idle time before sending first probe - CURLOPT_TCP_KEEPINTVL: delay between successive probes While not all operating systems support the TCP_KEEPIDLE and TCP_KEEPINTVL knobs, the library will still allow these options to be set by clients, silently ignoring the values.
