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.
2013-01-09build: 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.

2011-04-20CURL_DOES_CONVERSIONS: cleanupDaniel Stenberg
Massively reduce #ifdefs all over (23 #ifdef lines less so far) Moved conversion-specific code to non-ascii.c
2011-03-14protocols: use CURLPROTO_ internallyDaniel Stenberg
The PROT_* set of internal defines for the protocols is no longer used. We now use the same bits internally as we have defined in the public header using the CURLPROTO_ prefix. This is for simplicity and because the PROT_* prefix was already used duplicated internally for a set of KRB4 values. The PROTOPT_* defines were moved up to just below the struct definition within which they are used.
2011-03-14protocol handler: added flags fieldDaniel Stenberg
The protocol handler struct got a 'flags' field for special information and characteristics of the given protocol. This now enables us to move away central protocol information such as CLOSEACTION and DUALCHANNEL from single defines in a central place, out to each protocol's definition. It also made us stop abusing the protocol field for other info than the protocol, and we could start cleaning up other protocol-specific things by adding flags bits to set in the handler struct. The "protocol" field connectdata struct was removed as well and the code now refers directly to the conn->handler->protocol field instead. To make things work properly, the code now always store a conn->given pointer that points out the original handler struct so that the code can learn details from the original protocol even if conn->handler is modified along the way - for example when switching to go over a HTTP proxy.
2010-12-05Curl_send/recv_plain: return errno on failureDaniel Stenberg
When send() and recv() fail, we now store the errno value to allow the app to access it. Bug: http://curl.haxx.se/bug/view.cgi?id=3128121 Reported by: Yuri
2010-06-19sendrecv: treat all negative values from send/recv as errorsDaniel Stenberg
For example the libssh2 based functions return other negative values than -1 to signal errors and it is important that we catch them properly. Right before this, various failures from libssh2 were treated as negative download amounts which caused havoc.
2010-05-11sendrecv: make them two pairs of send/recv to properly deal with FTPSHoward Chu
FTP(S) use two connections that can be set to different recv and send functions independently, so by introducing recv+send pairs in the same manner we already have sockets/connections we can work with FTPS fine. This commit fixes the FTPS regression introduced in change d64bd82.
2010-05-07sendrecv: split the I/O handling into private handlerHoward Chu
Howard Chu brought the bulk work of this patch that properly moves out the sending and recving of data to the parts of the code that are properly responsible for the various ways of doing so. Daniel Stenberg assisted with polishing a few bits and fixed some minor flaws in the original patch. Another upside of this patch is that we now abuse CURLcodes less with the "magic" -1 return codes and instead use CURLE_AGAIN more consistently.

Matt Wixson found and fixed a bug in the SCP/SFTP area where the code treated a 0 return code from libssh2 to be the same as EAGAIN while in reality it isn't. The problem caused a hang in SFTP transfers from a MessageWay server.

2009-05-11Internal cleanup: KEEP_WRITE and KEEP_READ are now called KEEP_SEND andDaniel Stenberg
KEEP_RECV to better match the general terminology: receive and send is what we do from the (remote) servers. We read and write from and to the local fs.
2009-04-21libcurl's memory.h renamed to curl_memory.hYang Tse
2009-03-09- Frank Hempel found out a bug and provided the fix:Daniel Stenberg
curl_easy_duphandle did not necessarily duplicate the CURLOPT_COOKIEFILE option. It only enabled the cookie engine in the destination handle if data->cookies is not NULL (where data is the source handle). In case of a newly initialized handle which just had the cookie support enabled by a curl_easy_setopt(handle, CURL_COOKIEFILE, "")-call, handle->cookies was still NULL because the setopt-call only appends the value to data->change.cookielist, hence duplicating this handle would not have the cookie engine switched on. We also concluded that the slist-functionality would be suitable for being put in its own module rather than simply hanging out in lib/sendf.c so I created lib/slist.[ch] for them.

Markus Moeller reported: http://curl.haxx.se/mail/archive-2008-09/0016.html - recv() errors other than those equal to EAGAIN now cause proper CURLE_RECV_ERROR to get returned. This made test case 160 fail so I've now disabled it until we can figure out another way to exercise that logic.

2008-09-05- Introducing CURLOPT_CERTINFO and the corresponding CURLINFO_CERTINFO. ByDaniel Stenberg
enabling this feature with CURLOPT_CERTINFO for a request using SSL (HTTPS or FTPS), libcurl will gather lots of server certificate info and that info can then get extracted by a client after the request has completed with curl_easy_getinfo()'s CURLINFO_CERTINFO option. Linus Nielsen Feltzing helped me test and smoothen out this feature. Unfortunately, this feature currently only works with libcurl built to use OpenSSL. This feature was sponsored by networking4all.com - thanks!
