2013-12-22FILE: don't wait due to CURLOPT_MAX_RECV_SPEED_LARGEDaniel Stenberg
The FILE:// code doesn't support this option - and it doesn't make sense to support it as long as it works as it does since then it'd only block even longer. But: setting CURLOPT_MAX_RECV_SPEED_LARGE would make the transfer first get done and then libcurl would wait until the average speed would get low enough. This happened because the transfer happens completely in the DO state for FILE:// but then it would still unconditionally continue in to the PERFORM state where the speed check is made. Starting now, the code will skip from DO_DONE to DONE immediately if no socket is set to be recv()ed or send()ed to. Bug: http://curl.haxx.se/bug/view.cgi?id=1312 Reported-by: Mohammad AlSaleh
2013-12-01multi.c: Fixed compilation warningSteve Holme
warning: declaration of 'pipe' shadows a global declaration
2013-11-27multi.c: Fixed compilation error introduced in commit a900d45489fc14Steve Holme
Systems that define SIGPIPE_VARIABLE as a noop would not compile as restore_pipe was defined afterwards.
2013-11-27curl_multi_cleanup: ignore SIGPIPEJeff King
This is an extension to the fix in 7d80ed64e43515. We may call Curl_disconnect() while cleaning up the multi handle, which could lead to openssl sending packets, which could get a SIGPIPE. Signed-off-by: Jeff King <peff@peff.net>
2013-11-12multi: Small code tidy up to avoid hard returnSteve Holme
2013-11-11multi: Set read socket when returning READSOCK(0)Björn Stenberg
This patch fixes and issue introduced in commit 7d7df831981fee, if the tunnel state was TUNNEL_CONNECT, waitconnect_getsock() would return a bitmask indicating a readable socket but never stored the socket in the return array.
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.
2013-10-30curl_multi_wait: accept 0 from multi_timeout() as valid timeoutDaniel Stenberg
The code rejected 0 as a valid timeout while in fact the function could indeed legitimately return that and it should be respected. Reported-by: Bjorn 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.
2013-08-29curl_multi_remove_handle: allow multiple removesDaniel Stenberg
When removing an already removed handle, avoid that to ruin the internals and just return OK instead.
2013-08-28multi_socket: improved 100-continue timeout handlingDaniel Stenberg
When waiting for a 100-continue response from the server, the Curl_readwrite() will refuse to run if called until the timeout has been reached. We timeout code in multi_socket() allows code to run slightly before the actual timeout time, so for test 154 it could lead to the function being executed but refused in Curl_readwrite() and then the application would just sit idling forever. This was detected with runtests.pl -e on test 154.
2013-08-22multi: move on from STATE_DONE fasterDaniel Stenberg
Make sure we always return CURLM_CALL_MULTI_PERFORM when we reach CURLM_STATE_DONE since the state is transient and it can very well continue executing as there is nothing to wait for. Bug: http://curl.haxx.se/mail/lib-2013-08/0211.html Reported-by: Yi Huang
2013-08-20CURLM_ADDED_ALREADY: new error codeDaniel Stenberg
Doing curl_multi_add_handle() on an easy handle that is already added to a multi handle now returns this error code. It previously returned CURLM_BAD_EASY_HANDLE for this condition.
2013-08-20multi_init: moved init code here from add_handleDaniel Stenberg
The closure_handle is "owned" by the multi handle and it is unconditional so the setting up of it should be in the Curl_multi_handle function rather than curl_multi_add_handle.
2013-08-20multi: remove dns cache creation code from *add_handleDaniel Stenberg
As it is done unconditionally in multi_init() this code will never run!
2013-08-12multi: s/easy/dataDaniel Stenberg
With everything being struct SessionHandle pointers now, this rename makes multi.c use the library-wide practise of calling that pointer 'data' instead of the previously used 'easy'.
2013-08-12cleanup: removed one function, made one staticDaniel Stenberg
Moved Curl_easy_addmulti() from easy.c to multi.c, renamed it to easy_addmulti and made it static. Removed Curl_easy_initHandleData() and uses of it since it was emptied in commit cdda92ab67b47d74a.
2013-08-09comments: remove old and wrong multi/easy interface statementsDaniel Stenberg
2013-08-08global dns cache: didn't work [regression]Daniel Stenberg
CURLOPT_DNS_USE_GLOBAL_CACHE broke in commit c43127414d89ccb (been broken since the libcurl 7.29.0 release). While this option has been documented as deprecated for almost a decade and nobody even reported this bug, it should remain functional. Added test case 1512 to verify
2013-08-06FTP: when EPSV gets a 229 but fails to connect, retry with PASVDaniel Stenberg
This is a regression as this logic used to work. It isn't clear when it broke, but I'm assuming in 7.28.0 when we went all-multi internally. This likely never worked with the multi interface. As the failed connection is detected once the multi state has reached DO_MORE, the Curl_do_more() function was now expanded somewhat so that the ftp_do_more() function can request to go "back" to the previous state when it makes another attempt - using PASV. Added test case 1233 to verify this fix. It has the little issue that it assumes no service is listening/accepting connections on port 1... Reported-by: byte_bucket in the #curl IRC channel
2013-08-03multi: remove the one_easy struct fieldDaniel Stenberg
Since the merge of SessionHandle with Curl_one_easy, this indirection isn't used anymore.
2013-08-03multi: rename all Curl_one_easy to SessionHandleDaniel Stenberg
2013-08-03multi: remove the multi_pos struct fieldDaniel Stenberg
Since Curl_one_easy is really a SessionHandle now, this indirection doesn't exist anymore.
2013-08-03multi: remove easy_handle struct fieldDaniel Stenberg
It isn't needed anymore
2013-08-03multi: remove 'Curl_one_easy' struct, phase 1Daniel Stenberg
The motivation for having a separate struct that keep track of an easy handle when using the multi handle was removed when we switched to always using the multi interface internally. Now they were just two separate struct that was always allocated for each easy handle. This first step just moves the Curl_one_easy struct members into the SessionHandle struct and hides this somehow (== keeps the source code changes to a minimum) by defining Curl_one_easy to SessionHandle The biggest changes in this commit are: 1 - the linked list of easy handles had to be changed somewhat due to the new struct layout. This made the main linked list pointer get renamed to 'easyp' and there's also a new pointer to the last node, called easylp. It is no longer circular but ends with ->next pointing to NULL. New nodes are still added last. 2 - easy->state is now called easy->mstate to avoid name collision

2013-07-21curl_multi_wait: fix reventsDaniel Stenberg
Commit 6d30f8ebed34e7276 didn't work properly. First, it used the wrong array index, but this fix also: 1 - only does the copying if indeed there was any activity 2 - makes sure to properly translate between internal and external bitfields, which are not guaranteed to match Reported-by: Evgeny Turnaev

Pass back the revents that happened for the user-provided file descriptors.
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
2013-06-11multi_socket: reduce timeout inaccuracy marginDaniel Stenberg
Allow less room for "triggered too early" mistakes by applications / timers on non-windows platforms. Starting now, we assume that a timeout call is never made earlier than 3 milliseconds before the actual timeout. This greatly improves timeout accuracy on Linux. Bug: http://curl.haxx.se/bug/view.cgi?id=1228 Reported-by: Hang Su
2013-06-04curl_multi_wait: only use internal timer if not -1Daniel Stenberg
commit 29bf0598aad5 introduced a problem when the "internal" timeout is prefered to the given if shorter, as it didn't consider the case where -1 was returned. Now the internal timeout is only considered if not -1. Reported-by: Tor Arntsen Bug: http://curl.haxx.se/mail/lib-2013-06/0015.html
2013-06-03curl_multi_wait: reduce timeout if the multi handle wants toDaniel Stenberg
If the multi handle's pending timeout is less than what is passed into this function, it will now opt to use the shorter time anyway since it is a very good hint that the handle wants to process something in a shorter time than what otherwise would happen. curl_multi_wait.3 was updated accordingly to clarify This is the reason for bug #1224 Bug: http://curl.haxx.se/bug/view.cgi?id=1224 Reported-by: Andrii Moiseiev
2013-06-03multi_runsingle: switch an if() condition for readabilityDaniel Stenberg
... because there's an identical check right next to it so using the operators in the check in the same order increases readability.
2013-05-30multi_runsingle: add braces to clarify the codeDaniel Stenberg
2013-04-26curl_easy_init: use less mallocsDaniel Stenberg
By introducing an internal alternative to curl_multi_init() that accepts parameters to set the hash sizes, easy handles will now use tiny socket and connection hash tables since it will only ever add a single easy handle to that multi handle. This decreased the number mallocs in test 40 (which is a rather simple and typical easy interface use case) from 1142 to 138. The maximum amount of memory allocated used went down from 118969 to 78805.

2013-03-13Multiple pipelines and limiting the number of connections.Linus Nielsen Feltzing
Introducing a number of options to the multi interface that allows for multiple pipelines to the same host, in order to optimize the balance between the penalty for opening new connections and the potential pipelining latency. Two new options for limiting the number of connections: CURLMOPT_MAX_HOST_CONNECTIONS - Limits the number of running connections to the same host. When adding a handle that exceeds this limit, that handle will be put in a pending state until another handle is finished, so we can reuse the connection. CURLMOPT_MAX_TOTAL_CONNECTIONS - Limits the number of connections in total. When adding a handle that exceeds this limit, that handle will be put in a pending state until another handle is finished. The free connection will then be reused, if possible, or closed if the pending handle can't reuse it. Several new options for pipelining: CURLMOPT_MAX_PIPELINE_LENGTH - Limits the pipeling length. If a pipeline is "full" when a connection is to be reused, a new connection will be opened if the CURLMOPT_MAX_xxx_CONNECTIONS limits allow it. If not, the handle will be put in a pending state until a connection is ready (either free or a pipe got shorter). CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE - A pipelined connection will not be reused if it is currently processing a transfer with a content length that is larger than this. CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE - A pipelined connection will not be reused if it is currently processing a chunk larger than this. CURLMOPT_PIPELINING_SITE_BL - A blacklist of hosts that don't allow pipelining. CURLMOPT_PIPELINING_SERVER_BL - A blacklist of server types that don't allow pipelining. See the curl_multi_setopt() man page for details.
2013-03-09curl_multi_wait: avoid second loop if nothing to doDaniel Stenberg
... hopefully this will also make clang-analyzer stop warning on potentional NULL dereferences (which were false positives anyway).
2013-03-09multi_runsingle: avoid NULL dereferenceDaniel Stenberg
When Curl_do() returns failure, the connection pointer could be NULL so the code path following needs to that that into account. Bug: http://curl.haxx.se/mail/lib-2013-03/0062.html Reported by: Eric Hu

Remove internal separated behavior of the easy vs multi intercace. curl_easy_perform() is now using the multi interface itself. Several minor multi interface quirks and bugs have been fixed in the process. Much help with debugging this has been provided by: Yang Tse
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.
