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.

2014-12-04sws: try to remove socket and retry bindPeter Wu
If sws is killed it might leave a stale socket file on the filesystem which would cause an EADDRINUSE error. After this patch, it is checked whether the socket is really stale and if so, the socket file gets removed and another bind is executed. Signed-off-by: Peter Wu <peter@lekensteyn.nl>
2014-12-04sws: add UNIX domain socket supportPeter Wu
This extends sws with a --unix-socket option which causes the port to be ignored (as the server now listens on the path specified by --unix-socket). This feature will be available in the following patch that enables checking for UNIX domain socket support. Proxy support (CONNECT) is not considered nor tested. It does not make sense anyway, first connecting through a TCP proxy, then let that TCP proxy connect to a UNIX socket. Signed-off-by: Peter Wu <peter@lekensteyn.nl>
2014-12-04sws: restrict TCP_NODELAY to IP socketsPeter Wu
TCP_NODELAY does not make sense for Unix sockets, so enable it only if the socket is using IP. Signed-off-by: Peter Wu <peter@lekensteyn.nl>

sws.c:69: warning: comma at end of enumerator list
2014-11-30sws: move away from IPv4/IPv4-only assumptionPeter Wu
Instead of depending the socket domain type on use_ipv6, specify the domain type (AF_INET / AF_INET6) as variable. An enum is used here with switch to avoid compiler warnings in connect_to, complaining that rc is possibly undefined (which is not possible as socket_domain is always set). Besides abstracting the socket type, make the debugging messages be independent on IP (introduce location_str which points to "port XXXXX"). Rename "ipv_inuse" to "socket_type" and tighten the scope (main). Signed-off-by: Peter Wu <peter@lekensteyn.nl>

2013-06-04sws: support extracting test number from CONNECT ipv6-address!Daniel Stenberg
If an ipv6-address is provided to CONNECT, the last hexadecimal group in the address will be used as the test number! For example the address "[1234::ff]" would be treated as test case 255.
2013-03-27test1509: verify proxy header response headers countDaniel Stenberg
Modified sws to support and use custom CONNECT responses instead of the previously naive hard-coded version. Made the HTTP test server able to extract test case number from the host name in a CONNECT request by finding the number after the last dot. It makes 'machine.moo.123' use test case 123. Adapted a larger amount of tests to the new <connect> style. Bug: http://curl.haxx.se/bug/view.cgi?id=1204 Reported by: Martin Jansen
2013-03-15HTTP proxy: insert slash in URL if missingDaniel Stenberg
curl has been accepting URLs using slightly wrong syntax for a long time, such as when completely missing as slash "http://example.org" or missing a slash when a query part is given "http://example.org?q=foobar". curl would translate these into a legitimate HTTP request to servers, although as was shown in bug #1206 it was not adjusted properly in the cases where a HTTP proxy was used. Test 1213 and 1214 were added to the test suite to verify this fix. The test HTTP server was adjusted to allow us to specify test number in the host name only without using any slashes in a given URL. Bug: http://curl.haxx.se/bug/view.cgi?id=1206 Reported by: ScottJi

2012-08-07sws: close sockets properlyJoe Mason
Fix a bug where closed sockets (fd -1) were left in the all_sockets list, because of missing parens in a pointer arithmetic expression Reenable the tests that were locking up due to this bug.
2012-08-07Remove debug logs that were accidentally checked inJoe Mason
2012-08-07Use select in sws, which has better cross-platform support than pollJoe Mason
2012-08-07Use cross-platform curlx_nonblock instead of fcntl in swsJoe Mason
2012-08-02Add a polling loop in main to read from more than one socket at once. Add ↵Joe Mason
the O_NONBLOCK and SO_KEEPALIVE flag to all sockets. Note that several loops which used to continue on a return value of 0 (theoretical since 0 would never be returned without O_NONBLOCK) now break on 0 so that they won't continue reading until after poll is called again.
2012-08-02Change return values of get_request, accept_connection and ↵Joe Mason
service_connection to add a return code for non-blocking sockets: now -1 means error or connection finished, 1 means data was read, and 0 means there is no data available now so need to wait for poll (new return value)
2012-08-02Hoist the loop out of get_request, and make sure that it can be reentered ↵Joe Mason
when a request is half-finished. Note the the req struct used to be re-initialized AFTER reading pipeline data, so now that we initialize it from the caller we must be careful not to overwrite the pipeline data. Also we now need to handle the case where the buffer is already full when get_request is called - previously this never happened as it was always called with an empty buffer and looped until done. Now get_request is called in a loop, so the next step is to run the loop on a socket only when poll signals it is readable.
2012-08-02Move blocks of code from the sws main loop into their own functions for ↵Joe Mason
easier refactoring later. The next step will be to call the correct function after a poll, rather than looping unconditionally
2012-08-02Remove the --fork option of sws, since it makes refactoring to use poll more ↵Joe Mason
complicated and should be redundant once we poll
2012-07-12SWS: use of uninitialized memory fixDaniel Stenberg
I made "connmon" not get initialized properly before use, and I use the big hammer and make sure we always clear the entire struct to avoid any problem like this in the future.
2012-07-12connection-monitor: always log disconnect when enabledDaniel Stenberg
This makes verifying easier and makes us more sure curl closes the connection only at the correct point in time. Adjusted test 206 and 1008 accordingly and updated the docs for it.
2012-07-05sws: support <servercmd> for CONNECT requestsDaniel Stenberg
I moved out the servercmd parsing into a its own function called parse_servercmd() and made sure it gets used also when the test number is extracted from CONNECT requests. It turned out sws didn't do that previously!
2012-07-05sws: add 'connection-monitor' command supportDaniel Stenberg
Using this, the server will output in the protocol log when the connection gets disconnected and thus we will verify correctly in the test cases that the connection doesn't get closed prematurely. This is important for example NTLM to work. Documentation added to FILEFORMAT, test 503 updated to use this.

2012-01-03test proxy supports CONNECTDaniel Stenberg
There's a new 'http-proxy' server for tests that runs on a separate port and lets clients do HTTP CONNECT to other ports on the same host to allow us to test HTTP "tunneling" properly. Test cases now have a <proxy> section in <verify> to check that the proxy protocol part matches correctly. Test case 80, 83, 95, 275, 503 and 1078 have been converted. Test 1316 was added.
2011-10-14sws.c: HTTP and GOPHER test server-side connection closing adjustmentYang Tse
When, for a given test, server is instructed to close connection after server reply we now wait a very small amount of time (50ms) before doing so. This is done to allow client to, at least partially, read server reply before getting an ECONNRESET. The above is required to make test cases 1070, 1200, 1201 and 1202 pass with Cygwin 1.5.X on W2K. GOPHER test server closes connection after _every_ server-reply, as such, at some point it could require a bigger time or using shutdown() before a server-side initiated disconnection.
