On Unix, libwebsockets.pc
is installed. But it doesn't specify the version number; it's blank. E.g.:
prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
Name: libwebsockets
Description: Websockets server and client library
Version:
Libs: -L${libdir} -lwebsockets
It would be good to put the version number in the Version:
line.
Hi,
I'm going to use libwebsockets in my project and I use CMake for building this project. Thus, I created simple CMake find module that find libwebsockets library. It was tested at Linux:
https://gist.github.com/jirihnidek/5865660
May by, this will be useful for others.
Cheers,
Jiri
Hi,
also under Windows SO_REUSEADDR is needed, otherwise you can not bind if you are restarting a crashed service.

i just got a new router, previous problem of partial page load is still present
websocket is working fine
loading a 22414bytes page, the last 1kb is missing
im hoping if this can be resolved i can resolve an issue im having with my own library and mangled data across the router. no problems directly connecting to the modem.
I'm using the current version of the library (v1.3). I'm using the lws_hdr_total_length/lws_hdr_copy functions to parse URI request and the both seg fault (11). lws_hdr_copy calls lws_hdr_total_length which seg faults.
I can find the function prototypes in libwebsockets.h but there's no corresponding functions declaration in libwebsockets.c.
Why we remove the support for old websocket protocol? The previous release have full support but the latest not. Some web client still us old protocol such as webkit in QT 4.8.1
Dear warmcat,
I am working on sending a file with post request and find i have to parse the multipart http body myself and then record file, so is it possible libwebsocket realize this parse function?
This shouldn't be an issue, but i have no other way to submit, sorry.
Thanks

A few parameters (like "${PROJECT_BINARY_DIR}/lws_config.h" and "${PROJECT_SOURCE_DIR}/lib") are passed to CMake commands in your build script without enclosing them by quotation marks. I see that these places will result in build difficulties if the contents of the used variables will contain special characters like spaces.
I would recommend to apply advices from a Wiki article.

i cant find any libcyassl.a
the test in https://github.com/warmcat/libwebsockets/blob/master/lib/libwebsockets.c#L116 doesnt make sense
file descriptor 0 is legit after an accept - in particular you will get this if you have a demon-type setup where stdin, stdout stderr are typically closed. The way fd's are recycled you will get fd 0 on first accept after closing stdin.
suggestion: remove or mark an invalid fd as < 0.

When you compile with LWS_NO_SERVER you get compiler error.
As I understand there should be libwebsocket instead of libswebsocket.
In line 77 of lib\private-libwebsockets.h, in macro definition for compatible_file_read(), it stores the file read count into 'amount' instead of '_amount' - should read:

Dear,
I downloaded the latest libwebsocket from github, yes, it supports http post now, but when i run libwebsocket-test-server and access to http://localhost:7681/test.html, i got
lwsts[2821]: choked before able to send whole file (post), and the server won't give any response any more.
But the former released version has no this issue, could u tell me how to solve this issue?
Thanks in advance

I am getting the following printout error when I call libwebwsocket_write() for the first time.
[1374954782:4840] ERR: Unable to spill ext 7669 vs 5792
From tracing the code a little the error feels like I am trying to write too much in a message. However, i didn't think there was a limit on the message size.
Can you clue me into the meaning of the "unable to spill ext" error?

the last change in lib/private-libwebsockets.h by the commit e5720a3
introduced a compilation error in MinGW-w64 (gcc 4.8.2) on Win7
it can be resolved by replacing in lib/private-libwebsockets.h line 33

Description:
According to RFC2616, all header field names in both HTTP requests and HTTP responses are case-insensitive. But libwebsockets uses a case-sensitive compare.
Reproduce:
Run libwebsockets against a server that sends all of its HTTP header field names in lower-case (for example: https://github.com/extend/cowboy). libwebsockets reports an error. The expected behavior is no errors reported and a successful handshake procedure.

The problem: the header table isn't being freed. The fix is to make a change in handshake.c:230, changing:
default:
lwsl_warn("Unknown client spec version %d\n",
wsi->ietf_spec_revision);
goto bail;
}
to:
default:
lwsl_warn("Unknown client spec version %d\n",
wsi->ietf_spec_revision);
goto bail_nuke_ah;
}
The "bail_nuke_ah" label adds a free() of the header table:
bail_nuke_ah:
/* drop the header info */
if (wsi->u.hdr.ah)
free(wsi->u.hdr.ah);
bail:
lwsl_info("closing connection at libwebsocket_read bail:\n");
Note that the "goto bail"s and "goto bail_nuke_ah"s seem to be used almost interchangeably; someone should review them to make sure the right choices are being made.

windows Fix build.
Receiving bunch of errors on building on Window
"Error 23 error C2065: 'LWS_SSL_CAPABLE_ERROR' : undeclared identifier service.c 382"
Is there a way to dynamically add/change the protocols a server can recognize?Apologies if this is already addressed, but I couldn't find it in the docs/issues/header etc.
Thanks!
I'm using libwebsockets in my pilight home automation server to serve a webgui. This is working perfectly. Currently i'm implementing a php server capability. Until know everything works fine except one thing. When using sessions, PHP is requesting a
Set-Cookie: PHPSESSID=...; path=/
This means php wants me to store the PHPSESSID somewere and serve it with the subsequent calls as
HTTP_COOKIE="PHPSESSID=...;
So it know we are using the same session.
This means that when a user opens a browser sessions, i need the ability to store something for this whole browser session. When i open a new browser instance (e.g. firefox and chrome) i need to be able to store two distinct PHPSESSID. Apache can handle this perfectly, however, i can't get libwebsockets to store something per browser sessions instead of per page session.
Compilation fails because the ifdef factors out an enum which as the return value of a function that is not factored out.

SSL_connect on iOS with http proxy fails when SSL_connect can't connect immediately. The problem is that nonblocking BIO is used so in case SSL_connect() can't finish in one turn wsi->mode doesn't change from LWS_CONNMODE_WS_CLIENT_WAITING_PROXY_REPLY. So the next time we receive something on socket we fail on "HTTP/1.0 200" proxy connect check. I have made a quick fix. Please check here shyswork@b84971a
This is related to blocking sockets as of commit 6c58228. When I tried to use libwebsocket on iOS behind http proxy with nonblocking sockets I couldn't connect as well but I'm not sure if it is related to openssl or to the problem with libwebsockets and nonblocking sockets on iOS.
libwebsocket_create_context(...) crashes on a line 2163 of libwebsockets.c while trying to create a context for a port that is taken by the other instance of libwebsockets (i.e. an instance of websocket server with a port 9000 is running in a separate process and I'm trying to create a new websocket server on the very same port)
if (n < 0) {
lwsl_err("ERROR on binding to port %d (%d %d)\n",
info->port, n, errno);
close(sockfd); // this line leads to the crash
goto bail;
}
commenting out the "close(sockfd);" line seems to solve the issue so libwebsocket_create_context is able to return NULL if a particular port is taken, but I don't think it's a proper way to solve this.
I made a visual studio 2013 project via cmake.
Then built it in VS, but get 58 errors and 63 warnings.
What have I done wrong?

Is there a SUPER SIMPLE working example of a websocket client that would go like this:
int main () {
websocket ws = new websocket();
ws.connect();
ws.send();
...
}
Thank you!
I'm currently trying to cross compile libwebsockets (v1.23-chrome32-firefox24) on ubuntu using this toolchain.
http://wiki.blueocty.com/index.php?title=GNU_Toolchain
I've verifed that the toolchain works as I've compiled a sample binary for ARM.
As shown in README.build of libwebsockets, I've edited my cross-arm-linux-gnueabihf.cmake to the newly downloaded toolchain then ran CMake against it.
CMake runs successfully, although there's two things that concerns me.

I was under the impression that libwebsockets required zlib, but cmake finishes successfully for some reason.
Anyhow, now I try to do make. Immediately, I get an error.

make[1]: *** [CMakeFiles/websockets.dir/all] Error 2
make: *** [all] Error 2
It's strange, because I didn't get such label defined but not used errors when I compiled regularly instead of cross compiling. Anyhow, I turned off the -werror flag to stop warnings from halting my compilation, then tried make && make install, and the process successfully finishes (with the above error displayed as warning).
I've also verified that the library is compiled in ARM architecture.
root@ubuntu:/home/l46kok/Desktop/libwebsockets-1.23-chrome32-firefox24/build# file /usr/lib/libwebsockets.so.4.0.0
/usr/lib/libwebsockets.so.4.0.0: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked, not stripped
Then finally, I try to compile a very simple example code. For some reason, the compiler isn't able to find the header file to the library.
root@ubuntu:/home/l46kok/Desktop/websocketserver# arm-linux-gcc test.c -lwebsockets -o test
test.c:4:27: error: libwebsockets.h: No such file or directory
So I include the directory containing the header for the library.. and thousands of errors are generated from the libwebsocket library. Clearly, something must've gone wrong in the build process.

Here's the sample application that compiled and ran without any issue on gcc 4.7.3
I'm genuinely not sure how to fix this issue. The warnings and zlib.h missing is suspicious, but I'm not sure what exactly they indicate and how it's relevant to my problem. Any help would be appreciated.
I just cloned the repo and followed the README.build file instructions to build for Win 7 64 bit (but targeting 32 bit) in Visual Studio 2010. 3 projects succeded 8 failed. Many errors were related to the wsockcompat.h file. If the "include wsockcompat.h" in private-libwebsockets.h is removed then 9 projects succeed and only one fails (test-echo) due to an "unresolved external symbol _lws_daemonize referenced in function _main". Can I expect that the library runs without the wsockcompat.h file? How to remove the last linker error?
I would like to point out that identifiers like "__LIBWEBSOCKET_H__
" and "__ifaddrs_h__
" do not fit to the expected naming convention of the C language standard.
Would you like to adjust your selection for unique names?
libWebSockets - github 8/4/14 12.42pm GMT
CMake 2.9.12.2 - default config
Visual Studio 2010 Ult
Win7 Ult x64
Both debug/Release:
3>..\lib\client.c(154): error C2143: syntax error : missing ';' before 'const'
Quickfix: wrap the 3 lines 154-156 within a scope {}
-Werror is set in CMakeLists.txt line 312:
if (CMAKE_COMPILER_IS_GNUCC OR CMAKE_COMPILER_IS_GNUCXX)
if (UNIX)
set( CMAKE_C_FLAGS "-Wall -Werror -O4 -fvisibility=hidden ${CMAKE_C_FLAGS}" )
But this causes libwebsockets build to fail:
make

/home/grrrwaaa/code/libwebsockets/lib/libwebsockets.c:1815:13: error: ‘lws_sigusr2’ defined but not used [-Werror=unused-function]

make[2]: *** [CMakeFiles/websockets.dir/lib/libwebsockets.c.o] Error 1
make[1]: *** [CMakeFiles/websockets.dir/all] Error 2

Adding -Wno-unused-function after -Werror resolves the issue. Throwing build errors for unused functions seems overkill...
I just got into a situation where I think I found a bug in libwebsockets -- but it may also be a misunderstanding of the timeout mechanism, so any feedback is valid.
The idea here was to use libwebsockets timeouts to drop clients who never request anything (but keep the TCP session open), so they can not hold a file descriptor for too long, making poll queue longer, etc.
To get into this situation, run an unmodified libwebsockets-test-server, fire up a telnet to the address/port, and do nothing more -- the TCP session will remain open indefinitely. For comparison, do the same to an Apache/nginx webserver -- it will drop the connection after a while, freeing up the resources.
My approach was to set a timeout when the connection is established at network level (in callback LWS_CALLBACK_FILTER_NETWORK_CONNECTION) and remove it once a request or this socket is made in callback LWS_CALLBACK_FILTER_PROTOCOL_CONNECTION -- see the branch I linked bellow for the sample code --, dropping any client who does nothing but hold a file descriptor for too long. I'm not dropping connections after the request is completed because my real application will handle timeouts after this point.
The problem is LWS also times out the main control socket, closing and removing it from the FD lookup table. In the next iteration, the library will try to index in and crash.
I'm not sure if I'm using the timeouts it the right way, but I'm searching a solution for this.
I pushed a branch to demonstrate the (possible) bug with lws-test-server: ittner@bc79fee
Also, follows the GDB traces pointing to it:

I am trying to call libwebsocket_set_timeout()
, but it doesn't link (Ubuntu 13.10 64-bit).
I added LWS_VISIBLE
to the libwebsocket_set_timeout()
definition in libwebsockets.c
, and rebuilt the library. Then I was able to use it. But I'm not sure if that's the right way to do it.
Can we add some getters to imitate libwebsocket_callback_on_writable_all_protocol without using the private header (to go trough all connections and check if a flag is set in the user_space):
HEADER:
LWS_VISIBLE void *
libwebsockets_get_user_space(struct libwebsocket *wsi);
LWS_VISIBLE int
libwebsockets_get_fd_count(struct libwebsocket_context *context);
LWS_VISIBLE struct libwebsocket *
libwebsockets_get_wsi_at_index(struct libwebsocket_context *context, int index);
IMPLEMENTATION:
LWS_VISIBLE void *
libwebsockets_get_user_space(struct libwebsocket *wsi)
{
if (!wsi->protocol)
return NULL;
if (!wsi->protocol->per_session_data_size)
return NULL;
return wsi->user_space;
}
LWS_VISIBLE int
libwebsockets_get_fd_count(struct libwebsocket_context *context)
{
return context->fds_count;
}
LWS_VISIBLE struct libwebsocket *
libwebsockets_get_wsi_at_index(struct libwebsocket_context *context, int index)
{
if (index >= context->fds_count)
{
return NULL;
}
return context->lws_lookup[context->fds[index].fd];
}

With new nonblocking socket setting on iOS websocket is closed with EISCONN 56. It appears that in client-handshake.c in line 87 (https://github.com/warmcat/libwebsockets/blob/master/lib/client-handshake.c#L87) only EALREADY and EINPROGRESS are checked. In my situation I get there first time with EINPROGRESS which is ok but the next time I get EISCONN which leads to fail. I have put simple check for EISCONN as quick and dirty fix but I haven't tested it thoroughly.

Can you please move the line
struct libwebsocket_pollargs pa = {wsi->sock, POLLIN, 0 };
in function insert_wsi_socket_into_fds(...) to the beginning of the function, otherwise it con not be compiled under/for Windows (not sure what exact settings they are using...).
there are also some other problems because first you are accessing wsi->sock and afterwards you are asserting wsi and wsi->sock (should be done before - right?)
thank you
why is libwebsocket_write limited by that, my previous build was not limited
now i get ERROR writing, solved by increasing the max frame size / rx buffer to the size im trying to send.
but this wont fix my problem because i have big variances in the sizes im sending.
Hello,
I downloaded your lib today and I compiled it without the server support nor the SSL one:
"cmake -G "Visual Studio 10" -DLWS_WITH_SSL=0 -DLWS_WITHOUT_SERVER=1 -DLWS_WITHOUT_TEST_SERVER=1 -DLWS_WITHOUT_TEST_SERVER_EXTPOLL=1 -DLWS_WITHOUT_DEBUG=1 .."
And figured out that the function "libwebsocket_client_connect_2" @ "client-handshake.c" called the function name "interface_to_sa" which is not defined with such options.
A solution could be:
Also your README.build is outdated:
cmake -DWITH_SSL=0 ..
or
cmake -DWITH_SSL:BOOL=OFF ..
Should be:
cmake -DLWS_WITH_SSL=0 ..
or
cmake -DLWS_WITH_SSL:BOOL=OFF ..
Keep the hard work!
Best regards.
