Improvemed patches to address travis and appveyor build errors
Reduced WINVER and _WIN32_WINNT to 0x0501 to be less restrictive
Refined CMakeLists.txt to allow for normal Windows and MinGW-specific OpenSSL certificate generation
Simplified include path to gettimeofday.h
Removed unnecessary list(APPEND LWS_LIBRARIES zlib_internal) export
Added back #include <windows.h> to gettimeofday.c to fix build for normal Windows
Made sure that pollfd gets defined on libwebsockets side when _WIN32_WINNT < 0x0600
Made sure that WINVER and _WIN32_WINNT don't get overridden by libwebsockets headers when already set to something greater than 0x0501
Added missing declaration of WSAPoll function for WINVER < 0x0600 in libwebsockets.h, eliminated invalid usages of pollfd instead of libwebsocket_pollfd in test-server.c
Cleaned up duplicate content in gettimeofday.c, removed header inclusions from gettimeofday.h and fixed include order in test-echo.c, test-ping.c and test-server.c to enable build with normal Windows and MinGW
Re-enabled debug_level in test-echo.c and made sure that the call to lws_set_log_level() is also active under Windows (just like in test-server.c); replaced all WIN32 occurrences by _WIN32 in test-echo.c, test-ping.c, and test-server.c
Removed build-msys.sh and added new section about how to build libwebsockets using MinGW to README.build.md
- Got rid of ifdef _WIN32 stuff adn moved to plat_ files instead.
- Also, check all calls to lws_zalloc, was potential failure on WIN32
- Made context destory enable to destroy a half inited context as well. This way I got get rid of some of the error handling complexity in libwebsocket_create_context
- Added TODOs for some potential problems I see where things might be leaking and such
Since we include lws_config.h in the public headers, at least our HAVE_ macros should be kind of unique, so that we don't get redefinitions when used with other libraries using config files as well.
At least some win32 uses an opaque pointer for fd that is not
an ordinal like it is in unix.
Resurrect the old hashtable management for that platform to use
instead, and introduce a helper to get the wsi from the fd "somehow".
