2017-01-13unix_socket: add support for abstract unix domain socketIsaac Boukris
In addition to unix domain sockets, Linux also supports an abstract namespace which is independent of the filesystem. In order to support it, add new CURLOPT_ABSTRACT_UNIX_SOCKET option which uses the same storage as CURLOPT_UNIX_SOCKET_PATH internally, along with a flag to specify abstract socket. On non-supporting platforms, the abstract address will be interpreted as an empty string and fail gracefully. Also add new --abstract-unix-socket tool parameter.

2016-04-29lib: include curl_printf.h as one of the last headersDaniel Stenberg
curl_printf.h defines printf to curl_mprintf, etc. This can cause problems with external headers which may use __attribute__((format(printf, ...))) markers etc. To avoid that they cause problems with system includes, we include curl_printf.h after any system headers. That makes the three last headers to always be, and we keep them in this order: curl_printf.h curl_memory.h memdebug.h None of them include system headers, they all do funny #defines.

2015-12-07lwip: Fix compatibility issues with later versionsGisle Vanem
The name of the header guard in lwIP's <lwip/opt.h> has changed from '__LWIP_OPT_H__' to 'LWIP_HDR_OPT_H' (bug #35874 in May 2015). Other fixes: - In curl_setup.h, the problem with an old PSDK doesn't apply if lwIP is used. - In memdebug.h, the 'socket' should be undefined first due to lwIP's lwip_socket() macro. - In curl_addrinfo.c lwIP's getaddrinfo() + freeaddrinfo() macros need special handling because they were undef'ed in memdebug.h. - In select.c we can't use preprocessor conditionals inside select if MSVC and select is a macro, as it is with lwIP. http://curl.haxx.se/mail/lib-2015-12/0023.html http://curl.haxx.se/mail/lib-2015-12/0024.html
2015-03-16Bug #149: Deletion of unnecessary checks before calls of the function "free"Markus Elfring
The function "free" is documented in the way that no action shall occur for a passed null pointer. It is therefore not needed that a function caller repeats a corresponding check. http://stackoverflow.com/questions/18775608/free-a-null-pointer-anyway-or-check-first This issue was fixed by using the software Coccinelle 1.0.0-rc24.

2014-12-04libcurl: add UNIX domain sockets supportPeter Wu
The ability to do HTTP requests over a UNIX domain socket has been requested before, in Apr 2008 [0][1] and Sep 2010 [2]. While a discussion happened, no patch seems to get through. I decided to give it a go since I need to test a nginx HTTP server which listens on a UNIX domain socket. One patch [3] seems to make it possible to use the CURLOPT_OPENSOCKETFUNCTION function to gain a UNIX domain socket. Another person wrote a Go program which can do HTTP over a UNIX socket for Docker[4] which uses a special URL scheme (though the name contains cURL, it has no relation to the cURL library). This patch considers support for UNIX domain sockets at the same level as HTTP proxies / IPv6, it acts as an intermediate socket provider and not as a separate protocol. Since this feature affects network operations, a new feature flag was added ("unix-sockets") with a corresponding CURL_VERSION_UNIX_SOCKETS macro. A new CURLOPT_UNIX_SOCKET_PATH option is added and documented. This option enables UNIX domain sockets support for all requests on the handle (replacing IP sockets and skipping proxies). A new configure option (--enable-unix-sockets) and CMake option (ENABLE_UNIX_SOCKETS) can disable this optional feature. Note that I deliberately did not mark this feature as advanced, this is a feature/component that should easily be available.

2014-10-24code cleanup: we prefer 'CURLcode result'Daniel Stenberg
... for the local variable name in functions holding the return code. Using the same name universally makes code easier to read and follow. Also, unify code for checking for CURLcode errors with: if(result) or if(!result) instead of if(result == CURLE_OK), if(CURLE_OK == result) or if(result != CURLE_OK)
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.

2010-11-08CURLOPT_RESOLVE: addedDaniel Stenberg
CURLOPT_RESOLVE is a new option that sends along a curl_slist with name:port:address sets that will populate the DNS cache with entries so that request can be "fooled" to use another host than what otherwise would've been used. Previously we've encouraged the use of Host: for that when dealing with HTTP, but this new feature has the added bonus that it allows the name from the URL to be used for TLS SNI and server certificate name checks as well. This is a first change. Surely more will follow to make it decent.
