- Added options for compiling without server/client parts.
- Fixed a syntax error on printing an error on CyaSSL compilation.
- Don't compile server-extpoll either when the server isn't compiled.

- Small Size: 20-100kB
- Runtime Memory: 1-36kB
- 20X smaller than OpenSSL
So far only tested on Linux.
Note that this requires a bugfix in cyassl, otherwise it will crash. Pull request has been made to the official repos, in the meantime the following repos can be used: git://github.com/JoakimSoderberg/cyassl.git
- For some reason the "extern int pid_daemon" usage in libwebsockets.c would cause an "undefined symbols" linker error for the test-apps. This only happens with the CMake project, not the normal Makefiles. I have no clue why this is. Fixed it by getting the pid via a function instead.
- Added test-server-extpoll
- Renamed the library from libwebsocket -> libwebsockets
- Finalized CMake support (tested on windows only so far).
- Uses a generated lws_config.h that is included in
private-libwebsocket to pass defines, only used if CMAKE_BUILD is set.
- Support for SSL on Windows.
- Initial support for CyaSSL replacement of OpenSSL (This has been added
to my older CMake-fork but haven't been tested on this version yet).
- Fixed windows build (see below for details).
- Fixed at least the 32-bit Debug build for the existing Visual Studio
Project. (Not to keen fixing all the others when we have CMake support
anyway (which can generate much better project files)...)
- BUGFIXES:
- handshake.c
- used C99 definition of handshake_0405 function
- libwebsocket.c
- syslog not available on windows, put in ifdefs.
- Fixed previous known crash bug on Windows where WSAPoll in
Ws2_32.dll would not be present, causing the poll function pointer
being set to NULL.
- Uninitialized variable context->listen_service_extraseen would
result in stack overflow because of infinite recursion. Fixed by
initializing in libwebsocket_create_context
- SO_REUSADDR means something different on Windows compared to Unix.
- Setting a socket to nonblocking is done differently on Windows.
(This should probably broken out into a helper function instead)
- lwsl_emit_syslog -> lwsl_emit_stderr on Windows.
- private-libwebsocket.h
- PATH_MAX is not available on Windows, define as MAX_PATH
- Always define LWS_NO_DAEMONIZE on windows.
- Don't define lws_latency as inline that does nothing. inline is not
support by the Microsoft compiler, replaced with an empty define
instead. (It's __inline in MSVC)
- server.c
- Fixed nonblock call on windows
- test-ping.c
- Don't use C99 features (Microsoft compiler does not support it).
- Move non-win32 headers into ifdefs.
- Skip use of sighandler on Windows.
- test-server.c
- ifdef syslog parts on Windows.
This exposes the library version and git head hash it was built from
into LWS_LIBRARY_VERSION and LWS_BUILD_HASH.
These are combined into a version string that's both printed as a
notice log by the library and made available to the app using a new
api lws_get_library_version(). The version looks like
1.1 178d78c

With these explicit casts that are not needed in C, it's possible to build
the test server using g++ like this, after building and installing the
library.
g++ -DINSTALL_DATADIR=\"/usr/share\" -ocpptest test.cpp -lwebsockets
Add a small documentation to README.coding

Libwebsockets is fundamentally singlethreaded... the existence of the
fork and broadcast support, especially in the sample server is
giving the wrong idea about how to use it.
This replaces broadcast in the sample server with
libwebsocket_callback_on_writable_all_protocol(). The whole idea of
'broadcast' is removed.
All of the broadcast proxy stuff is removed: data must now be sent
from the callback only. Doing othherwise is not reliable since the
service loop may close the socket and free the wsi at any time,
invalidating a wsi pointer held by another thread (don't do that!)
Likewise the confirm_legit_wsi api added recently does not help the
other thread case, since if the wsi has been freed dereferencing the
wsi to study if it is legit or not will segfault in that case. So
this is removed too.
The overall effect is to push user code to only operate inside the
protocol callbacks or external poll loops, ie, single thread context.

Seems we just need to take care about __FreeBSD__ along with
__APPLE__ in a couple of places.

Comes in handy if the original application poll loop is the boss,
in this case libwebsockets is optional and can't be the boss poll
loop
