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.

|
|
.SH NAME
|
|
curl_easy_setopt \- set options for a curl easy handle
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLoption option, parameter);
|
|
.SH DESCRIPTION
|
|
\fIcurl_easy_setopt(3)\fP is used to tell libcurl how to behave. By setting
|
|
the appropriate options, the application can change libcurl's behavior. All
|
|
options are set with an \fIoption\fP followed by a \fIparameter\fP. That
|
|
parameter can be a \fBlong\fP, a \fBfunction pointer\fP, an \fBobject
|
|
pointer\fP or a \fBcurl_off_t\fP, depending on what the specific option
|
|
expects. Read this manual carefully as bad input values may cause libcurl to
|
|
behave badly! You can only set one option in each function call. A typical
|
|
application uses many \fIcurl_easy_setopt(3)\fP calls in the setup phase.
|
|
|
|
Options set with this function call are valid for all forthcoming transfers
|
|
performed using this \fIhandle\fP. The options are not in any way reset
|
|
between transfers, so if you want subsequent transfers with different options,
|
|
you must change them between the transfers. You can optionally reset all
|
|
options back to internal default with \fIcurl_easy_reset(3)\fP.
|
|
|
|
Strings passed to libcurl as 'char *' arguments, are copied by the library;
|
|
thus the string storage associated to the pointer argument may be overwritten
|
|
after \fIcurl_easy_setopt(3)\fP returns. The only exception to this rule is
|
|
really \fICURLOPT_POSTFIELDS(3)\fP, but the alternative that copies the string
|
|
\fICURLOPT_COPYPOSTFIELDS(3)\fP has some usage characteristics you need to
|
|
read up on.
|
|
|
|
Before version 7.17.0, strings were not copied. Instead the user was forced
|
|
keep them available until libcurl no longer needed them.
|
|
|
|
The \fIhandle\fP is the return code from a \fIcurl_easy_init(3)\fP or
|
|
\fIcurl_easy_duphandle(3)\fP call.

the library is too old to support it or the option was removed in a recent

version, this function will return \fICURLE_UNKNOWN_OPTION\fP. If support for

the option was disabled at compile-time, it will return
