There's no problem for library build, also with LWS_WITH_MINIMAL_EXAMPLES,
but after install at least on OSX, there are problems finding the installed
lws include dir (concealed on most platforms by the path being in the
default search list for the toolchain), and the references in the lws
includes to the tls includes meaning that explicit paths for that must be
available at consuming cmakes.
This patch enhances the cmake config installed by lws to deal with adding
the lws include paths to CMAKE_REQUIRED_INCLUDES and include_directories,
so it can be found before the target is introduced.
The tls include is passed back up the CMakeLists layers and the lws targets
marked with target_include_directories(PUBLIC) with them, so they are
understood as needed by consumers.
More boilerplate is moved out of the example consuming cmakes.
After this, on machines with previous installs of older lws, you may have to
clean out the cmake install path, that is usually something like
/usr/local/lib/cmake/libwebsockets/*
before make installing lws and putting the latest content in there.
Adds an example for NXP RT595S eval board, using serialized SS over CDC /
ACM USB composite device, one ttyACM for logs and the other for the SSS
link.
Add some exports so the api test can inject results into the parser for
live queries, suppressing asking the server but otherwise following the
flow.
Provide two new suspect responses for injection and parsing in ctest.
Add a --cos option to minimal-http-client to force a close after the
connection has started the async dns.
When the client goes away, on some platforms all we get is POLLIN revent
stuck on... we have to read it to find out a zero length result and
understand it's gone.
Add SSE mode's DOING_TRANSACTION to the list of states we will read for.
Of note: A single use of lwsl_debug() remains because the function in
question is documented as a public API, but the passed-in parameter
doesn’t offer a path to a logging context.
Added the ability to get additional form parameters with unknown names in the form parameters parser lws_spa. The example of using the form parameters parser has been updated. Fixed bug of double freeing memory in the example.
These have been disabled via a preprocessor symbol with no UI to enable it
for a year or so, it looks like they are not going to be needed.
The model of in-tree auth selectable from cmake looks like it will do for
everything, or if not, the solution will probably look different to this.
lws_sequencer and lws_abstract were both false starts trying to do the
functionality of secure streams.
Since Secure Streams does a better job for both and there are no known
out-of-tree users of them, let's remove them and focus on Secure Streams.
This is a NOP for existing usecases.
At the moment the only implemented transport for serialized SS is wsi, it's
typically used with Unix Domain Sockets, but it also works over tcp the
same.
It generalizes the interface between serialized chunks and the
transport, separately for client and proxy. The wsi transport is migrated
to use the new transport ops structs.
It will then be possible to "bring your own transport", so long as it is
reliable, and in-order, both for proxy and client / sspc.
We also adapt minimal-secure-streams-binance to build the -client variant
via SS proxy as well.
LWS_ONLY_SSPC is added so libwebsockets can be produced with just sspc
client support even for tiny targets.
A new embedded minimal example for rpi pico is also provided that
demonstrates using Serialized SS over a UART to an SS proxy, to implement
the SS Binance example on the pico, even though it has no networking itself.
With the timeout set to portMAX_DELAY, there is no timeout and so no way
for the api to return failure.

However Coverity doesn't understand this, and futher, Coverity usually
ignores (void) result casts. So add needless checks and the corresponding
needless unwinding to the 10 uses of lws_mutex_lock() in smd.c.
Invert the return value to align it with pthreads mutex lock return
semantics.
I’ve got an error when compiling libwebsockets on Mac with -DLWS_WITHOUT_SERVER=ON:
libwebsockets/lib/tls/tls.c:98:22: error: unused variable 'cx' [-Werror,-Wunused-variable]
Since CONNECTING is async and may take a while, there's nothing actually
wrong if the application asks to write again in the meanwhile and provokes
POLL.
This patch adapts the recent change about serializing the number of
simultaneous tls handshakes allowed to 1, so you can set the number in the
context creation info, and the accounting for it is handled by counters
same as the overally tls restriction.
The name of the context info var to control it changes to simultaneous_ssl_handshake_restriction
which is now a count, the default 0 means no limit.
The count rejects tls connection attempts when the tls borrow is attempted,
and separately hands back the hs borrow from the tls borrow when the
connection attempt fails or succeeds.
