If you vhost->options has the flag LWS_SERVER_OPTION_VHOST_UPG_STRICT_HOST_CHECK,
then if the server is sent an upgrade request, the content of the Host: header is
required to match the vhost name + port. The port is set to the well-known values
of 80 and 443 if no :port on the host: value, depending on tls or not on the
connection.
minimal-ws-server can now take a -h flag to set this. lejp-conf (eg, lwsws) can now take
a flag strict-host-check on the vhost to enable it as well.
This adds support for the integrating libdbus into the lws event loop.
Unlike the other roles, lws doesn't completely adopt the fd and libdbus insists
to retain control over the fd lifecycle. However libdbus provides apis for
foreign code (lws) to provide event loop services to libdbus for the fd.
Accordingly, unlike the other roles rx and writeable are not subsumed into
lws callback messages and the events remain the property of libdbus.
A context struct wrapper is provided that is available in the libdbus
callbacks to bridge between the lws and dbus worlds, along with
a minimal example dbus client and server.
This allows the client stuff to understand that addresses beginning with '+'
represent unix sockets.
If the first character after the '+' is '@', it understands that the '@'
should be read as '\0', in order to use Linux "abstract namespace"
sockets.
Further the lws_parse_uri() helper is extended to understand the convention
that an address starting with + is a unix socket, and treats the socket
path as delimited by ':', eg
http://+/var/run/mysocket:/my/path
HTTP Proxy is updated to allow mounts to these unix socket paths.
Proxy connections go out on h1, but are dynamically translated to h1 or h2
on the incoming side.
Proxy usage of libhubbub is separated out... LWS_WITH_HTTP_PROXY is on by
default, and LWS_WITH_HUBBUB is off by default.
This has no effect on user code or backward compatibility.
It moves the in-tree public api header libwebsockets.h from ./lib
to ./include, and introduces a dir ./include/libwebsockets/
The single public api header is split out into 31 sub-headers
in ./include/libwebsockets. ./include/libwebsockets.h contains
some core types and platform adaptation code, but the rest of it
is now 31 #include <libwebsockets/...>
At install time, /usr/[local/]include/libwebsockets.h is installed
as before, along now with the 31 sub-headers in ...include/libwebsockets/
There's no net effect on user code.
But the api header is now much easier to maintain and study, with 31
topic-based sub headers.
