2014-12-27code/docs: Use correct case for IPv4 and IPv6Steve Holme
For consistency, as we seem to have a bit of a mixed bag, changed all instances of ipv4 and ipv6 in comments and documentations to use the correct case.
2014-05-22bits.close: introduce connection close trackingDaniel Stenberg
Make all code use connclose() and connkeep() when changing the "close state" for a connection. These two macros take a string argument with an explanation, and debug builds of curl will include that in the debug output. Helps tracking connection re-use/close issues.

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.
2013-10-27Add "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.
2013-01-09build: 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.

2012-12-28build: make use of 76 lib/*.h renamed filesYang Tse
76 private header files renamed to use our standard naming scheme. This change affects 322 files in libcurl's source tree.
2011-12-20timeleft_accept: ack global timeout, moved to ftp.cDaniel Stenberg
First off the timeout for accepting a server connect back must of course respect a global timeout. Then the timeleft function is only used by ftp code so it was moved to ftp.c and made static.
2011-12-20FTP: perform active connections non-blockingGokhan Sengun
1- Two new error codes are introduced. CURLE_FTP_ACCEPT_FAILED to be set whenever ACCEPTing fails because of FTP server connected. CURLE_FTP_ACCEPT_TIMEOUT to be set whenever ACCEPTing timeouts. Neither of these errors are considered fatal and control connection remains OK because it could just be a firewall blocking server to connect to the client. 2- One new setopt option was introduced. CURLOPT_ACCEPTTIMEOUT_MS It sets the maximum amount of time FTP client is going to wait for a server to connect. Internal default accept timeout is 60 seconds.
2011-12-05Curl_socket: internal replacement for socket()Daniel Stenberg
Moved out into a separate function to work as a "generic" socket() replacement.
2011-09-03fix a bunch of MSVC compiler warningsYang Tse
2011-08-07BSD-style lwIP TCP/IP stack support - followupYang Tse
lwIP library initialization.
2011-05-18CLOSESOCKETFUNCTION: addedDaniel Stenberg
Introduced the initial setup to allow closesocket callbacks by making sure sclose() is only ever called from one place in the libcurl source and still run all test cases fine.
2011-01-04Curl_timeleft: s/conn/data in first argumentDaniel Stenberg
As the function doesn't really use the connectdata struct but only the SessionHanadle struct I modified what argument it wants.
2010-11-30fix getinfo CURLINFO_LOCAL* for reused connections (take 2)Yang Tse
2010-09-06portabilty: use proper variable type to hold socketsDaniel Stenberg
Curl_getconnectinfo() is changed to return a proper curl_socket_t for the last socket so that it'll work more portably (and cause less compiler warnings).
2010-06-07Curl_updateconninfo() error handling fixYang Tse
2010-06-05getinfo: added *_PRIMARY_PORT, *_LOCAL_IP and *_LOCAL_PORTFrank Meier
2010-03-24remove the CVSish $Id$ linesDaniel Stenberg
2009-07-09- Eric Wong introduced curlx_nonblock() that the curl tool now (re-)uses forDaniel Stenberg
setting a file descriptor non-blocking. Used by the functionality Eric himself brough on June 15th.
2009-05-07- Made the SO_SNDBUF setting for the data connection socket for ftp uploads asDaniel Stenberg
well. See change 28 Apr 2009.
2008-11-03- Bug #2218480 (http://curl.haxx.se/bug/view.cgi?id=2218480) pointed out aDaniel Stenberg
problem with my CURLINFO_PRIMARY_IP fix from October 7th that caused a NULL pointer read. I also took the opportunity to clean up this logic (storing of the connection's IP address) somewhat as we had it stored in two different places and ways previously and they are now unified.
2008-05-12- Introducing curl_easy_send() and curl_easy_recv(). They can be used to sendDaniel Stenberg
and receive data over a connection previously setup with curl_easy_perform() and its CURLOPT_CONNECT_ONLY option. The sendrecv.c example was added to show how they can be used.
2008-02-07- Refactored a lot of timeout code into a few functions in an attempt to makeDaniel Stenberg
them all use the same (hopefully correct) logic to make it less error-prone and easier to introduce library-wide where it should be used.
2007-02-16use macros ERRNO, SET_ERRNO(), SOCKERRNO and SET_SOCKERRNO() for errno handlingYang Tse
2006-07-21Constify some arguments in Curl_connecthost() and singleipconnect().Gisle Vanem
2006-05-04Roland Blom filed bug report #1481217Daniel Stenberg
(http://curl.haxx.se/bug/view.cgi?id=1481217), with follow-ups by Michele Bini and David Byron. libcurl previously wrongly used GetLastError() on windows to get error details after socket-related function calls, when it really should use WSAGetLastError() instead. When changing to this, the former function Curl_ourerrno() is now instead called Curl_sockerrno() as it is necessary to only use it to get errno from socket-related functions as otherwise it won't work as intended on Windows.
2005-01-29conn->ip_addr MUST NOT be used on re-used connectionsDaniel Stenberg
2004-06-30make the SSL connect use the same default connect timeout define as theDaniel Stenberg
generic connect uses
2004-06-29corrected the Curl_is_connected() protoDaniel Stenberg
2004-06-24Source cleanups. The major one being that we now _always_ use a Curl_addrinfoDaniel Stenberg
linked list for name resolved data, even on hosts/systems with only IPv4 stacks as this simplifies a lot of code.
2004-03-09Use curl_socket_t instead of int for holding sockets. The typedefs andDaniel Stenberg
defines are in setup.h.
2004-01-07updated year in the copyright stringDaniel Stenberg
2003-10-18gcc -Wshadow complaints fixedDaniel Stenberg
2003-05-01ourerrno became Curl_ourerrno() and is now available to all libcurlDaniel Stenberg
2003-01-16copyright year update in the source headerDaniel Stenberg
2002-11-05Curl_resolv() now returns a different struct, and it contains a referenceDaniel Stenberg
counter so that the caller needs to decrease that counter when done with the returned data. If compiled with MALLOCDEBUG I've added some extra checking that the counter is decreased before a handle is closed etc.
2002-09-03updated source code boilerplate/headerDaniel Stenberg
2002-08-12Initial fix to make the multi interface return control while waiting forDaniel Stenberg
the initial connect to "come through". This should work fine for connect and for FTP-PASV connects. Needs massive testing.
2002-03-19copyright string (year) updateDaniel Stenberg
2001-11-19long port => int port, as the c source uses! (Miklos Nemeth found this)Daniel Stenberg
2001-10-31nonblock => Curl_nonblock, remade the check for a live SSL connection (again)Daniel Stenberg
2001-10-05SM's patch applied, we should not use arguments or variables that have theDaniel Stenberg
same name as common functions...
