2015-06-09CURLOPT_OPENSOCKETFUNCTION: return error at onceDaniel Stenberg
When CURL_SOCKET_BAD is returned in the callback, it should be treated as an error (CURLE_COULDNT_CONNECT) if no other socket is subsequently created when trying to connect to a server. Bug: http://curl.haxx.se/mail/lib-2015-06/0047.html

... by using plain structs instead of pointers for the connection cache, we can avoid several dynamic allocations that weren't necessary.

This header file must be included after all header files except memdebug.h, as it does similar memory function redefinitions and can be similarly affected by conflicting definitions in system or dependent library headers.

2015-03-16connect: Fix happy eyeballs logic for IPv4-only buildsJay Satiro
Bug: https://github.com/bagder/curl/pull/168 (trynextip) - Don't try the "other" protocol family unless IPv6 is available. In an IPv4-only build the other family can only be IPv6 which is unavailable. This change essentially stops IPv4-only builds from attempting the "happy eyeballs" secondary parallel connection that is supposed to be used by the "other" address family. Prior to this change in IPv4-only builds that secondary parallel connection attempt could be erroneously used by the same family (IPv4) which caused a bug where every address after the first for a host could be tried twice, often in parallel. This change fixes that bug. An example of the bug is shown below. Assume MTEST resolves to 3 addresses 127.0.0.2, 127.0.0.3 and 127.0.0.4: * STATE: INIT => CONNECT handle 0x64f4b0; line 1046 (connection #-5000) * Rebuilt URL to: http://MTEST/ * Added connection 0. The cache now contains 1 members * STATE: CONNECT => WAITRESOLVE handle 0x64f4b0; line 1083 (connection #0) * Trying 127.0.0.2... * STATE: WAITRESOLVE => WAITCONNECT handle 0x64f4b0; line 1163 (connection #0) * Trying 127.0.0.3... * connect to 127.0.0.2 port 80 failed: Connection refused * Trying 127.0.0.3... * connect to 127.0.0.3 port 80 failed: Connection refused * Trying 127.0.0.4... * connect to 127.0.0.3 port 80 failed: Connection refused * Trying 127.0.0.4... * connect to 127.0.0.4 port 80 failed: Connection refused * connect to 127.0.0.4 port 80 failed: Connection refused * Failed to connect to MTEST port 80: Connection refused * Closing connection 0 * The cache now contains 0 members * Expire cleared curl: (7) Failed to connect to MTEST port 80: Connection refused The bug was born in commit bagder/curl@2d435c7.
2015-03-15closesocket: call multi socket cb on close even with custom closeFrank Meier
In function Curl_closesocket() in connect.c the call to Curl_multi_closed() was wrongly omitted if a socket close function (CURLOPT_CLOSESOCKETFUNCTION) is registered. That would lead to not removing the socket from the internal hash table and not calling the multi socket callback appropriately. Bug: http://curl.haxx.se/bug/view.cgi?id=1493

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.
2014-12-16IPV6: address scope != scope idPatrick Monnerat
There was a confusion between these: this commit tries to disambiguate them. - Scope can be computed from the address itself. - Scope id is scope dependent: it is currently defined as 1-based local interface index for link-local scoped addresses, and as a site index(?) for (obsolete) site-local addresses. Linux only supports it for link-local addresses. The URL parser properly parses a scope id as an interface index, but stores it in a field named "scope": confusion. The field has been renamed into "scope_id". Curl_if2ip() used the scope id as it was a scope. This caused failures to bind to an interface. Scope is now computed from the addresses and Curl_if2ip() matches them. If redundantly specified in the URL, scope id is check for mismatch with the interface index. This commit should fix SF bug #1451.

2014-12-04updateconninfo: clear destination struct before getsockname()Daniel Stenberg
Otherwise we may read uninitialized bytes later in the unix-domain sockets case.
2014-11-30lib/connect: restrict IP/TCP options to said socketsPeter Wu
This patch prepares for adding UNIX domain sockets support. TCP_NODELAY and TCP_KEEPALIVE are specific to TCP/IP sockets, so do not apply these to other socket types. bindlocal only works for IP sockets (independent of TCP/UDP), so filter that out too for other types.

2014-11-19multi: inform about closed sockets before they are closedJon Spencer
When the connection code decides to close a socket it informs the multi system via the Curl_multi_closed function. The multi system may, in turn, invoke the CURLMOPT_SOCKETFUNCTION function with CURL_POLL_REMOVE. This happens after the socket has already been closed. Reorder the code so that CURL_POLL_REMOVE is called before the socket is closed.

2014-08-31low-speed-limit: avoid timeout floodDaniel Stenberg
Introducing Curl_expire_latest(). To be used when we the code flow only wants to get called at a later time that is "no later than X" so that something can be checked (and another timeout be added). The low-speed logic for example could easily be made to set very many expire timeouts if it would be called faster or sooner than what it had set its own timer and this goes for a few other timers too that aren't explictiy checked for timer expiration in the code. If there's no condition the code that says if(time-passed >= TIME), then Curl_expire_latest() is preferred to Curl_expire(). If there exists such a condition, it is on the other hand important that Curl_expire() is used and not the other. Bug: http://curl.haxx.se/mail/lib-2014-06/0235.html Reported-by: Florian Weimer

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.
2014-05-15timers: fix timer regression involving redirects / reconnectsDaniel Stenberg
In commit 0b3750b5c23c25f (released in 7.36.0) we fixed a timeout issue but instead broke the timings. To fix this, I introduce a new timestamp to use for the timeouts and restored the previous timestamp and timestamp position so that the old timer functionality is restored. In addition to that, that change also broke connection timeouts for when more than one connect was used (as it would then count the total time from the first connect and not for the most recent one). Now Curl_timeleft() has been modified so that it checks against different start times depending on which timeout it checks. Test 1303 is updated accordingly.
