Don't mess with system types is no problem on a unix system with sys/types.h However on Windows it will result in a #undef pid_t ... When libwebsockets is used with pthreads32 which typedefs pid_t itself, it will fail to build with some weird errors. Also since we're exporitng these macros to the entire world via libwebsockets.h we should not define a VERSION macro. Which is defined improperly anyway.

Some more Cmake stuff.

Subject: [PATCH] Multiple changes in the build process * Default CMAKE_BUILD_TYPE to Release * Use CMAKE_BUILD_TYPE to define _DEBUG (NDEBUG is more standard though, but cmake defines it) * Drop LWS_WITHOUT_DEBUG (use CMAKE_BUILD_TYPE for that) * Drop LWS_NO_EXTERNAL_POLL (was not used) * Drop CMAKE_BUILD (CMake is the only build system now) * Add LWS_WITH_STATIC and LWS_WITH_SHARED to choose what version(s) to build * Add LWS_XXX_LIBRARIES and LWS_XXX_INCLUDE_DIRS for each library dependency (zlib, openssl, libev, cyassl) * Support setting of XXX_LIBRARIES, XXX_LIBRARIES and XXX_INCLUDE_DIRS by parent project (when included with add_subdirectory()) * Rename LWS_USE_EXTERNAL_ZLIB to LWS_USE_BUNDLED_ZLIB and default it to NO (since it's Windows only) * Default LWS_WITHOUT_DAEMONIZE to NO (since network lib shouldn't know how to do it anyway) * Rename config.h.cmake to lws_config.h.in * Rename shared library to websockets_shared so linker will not be confused * Fix inline keyword detection in clang * Explicitly set MACOSX_RPATH to YES on MacOS

event libs: default to building as dynamically loaded plugins Event lib support as it has been isn't scaling well, at the low level libevent and libev headers have a namespace conflict so they can't both be built into the same image, and at the distro level, binding all the event libs to libwebsockets.so makes a bloaty situation for packaging, lws will drag in all the event libs every time. This patch implements the plan discussed here https://github.com/warmcat/libwebsockets/issues/1980 and refactors the event lib support so they are built into isolated plugins and bound at runtime according to what the application says it wants to use. The event lib plugins can be packaged individually so that only the needed sets of support are installed (perhaps none of them if the user code is OK with the default poll() loop). And dependent user code can mark the specific event loop plugin package as required so pieces are added as needed. The eventlib-foreign example is also refactored to build the selected lib support isolated. A readme is added detailing the changes and how to use them. https://libwebsockets.org/git/libwebsockets/tree/READMEs/README.event-libs.md

Subject: [PATCH] Add LWS_LIBRARY_VERSION_NUMBER to lws_config.h. This changeset adds a few preprocessor macros to lws_config.h to allow a user of libwebsockets to determine at compile time which version of lws they are compiling against. This exposes the already existing LWS_LIBRARY_VERSION_MAJOR and _MINOR values, and adds LWS_LIBRARY_VERSION_PATCH. This suggests that future minor bugfix release versions of lws would be e.g. 1.6.0 -> 1.6.1 rather than the style used previously: 1.2 -> 1.21. The way this is currently set up means new minor revisions (with _PATCH==0) always end with .0 but I could change this if preferred. The most important addition is LWS_LIBRARY_VERSION_NUMBER, which produces a number of the form 1005001 for version 1.5.1 - i.e. each part major, minor, patch can extend from 0-999. This macro allows a very easy compile time comparison of version numbers.

esp32: shift to support latest esp-idf Esp-idf has an improved but still kind of abused cmake- based build system now. If we see ESP_PLATFORM coming as a cmake var, we can know we are being built from inside the esp-idf config system. Leave the existing esp32 arrangements alone but triggered off ESP_PLATFORM, adapt to use the cross toolchain file and various quirks automatically. In this way you can build lws a part of your project in a much cleaner way. Prepare a minimal esp32 test app for use in Sai Adapt .sai.json to build for esp32

windows: pthreads Add support for external pthreads lib on windows and some docs about how to do. It can build with LWS_WITH_THREADPOOL and LWS_WITH_MINIMAL_EXAMPLES including the pthreads-dependent ones without warnings or errors on windows platform as well with this. pthreads_t can be anything, including a struct - not a pointer-to-a-struct but the struct itself. These can't be cast to a void * for printing as they can on linux, where the base type is a pointer. Let's fix all the usage of those to determine their own thread index in terms of the meaning to the program rather than as a tid.

CMake support + fixed windows build. - 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.

unify us sorted waits There are quite a few linked-lists of things that want events after some period. This introduces a type binding an lws_dll2 for the list and a lws_usec_t for the duration. The wsi timeouts, the hrtimer and the sequencer timeouts are converted to use these, also in the common event wait calculation.

opensslv3: handle deprecation of EC apis openssl v3-alpha11 has marked EC_KEY pieces as deprecated... we use it in LWS_WITH_GENCRYPTO but the related RSA etc pieces were already deprecated for that. We use EC_KEY pieces in vhost init... The apis are not removed but deprecated, we should have a way to keep trucking, but as it is the deprecation warning is promoted to an error. Let's add LWS_SUPPRESS_DEPRECATED_API_WARNINGS option off by default. If enabled at cmake, external deprecated api warnings are suppressed. This gives a general workaround for now for opensslv3. In addition, even if you don't do that, let's notice we are on openssl v3 and don't build the EC curve selection stuff, I don't think anyone is actually using it anyway.

type comparisons: fixes This is a huge patch that should be a global NOP. For unix type platforms it enables -Wconversion to issue warnings (-> error) for all automatic casts that seem less than ideal but are normally concealed by the toolchain. This is things like passing an int to a size_t argument. Once enabled, I went through all args on my default build (which build most things) and tried to make the removed default cast explicit. With that approach it neither change nor bloat the code, since it compiles to whatever it was doing before, just with the casts made explicit... in a few cases I changed some length args from int to size_t but largely left the causes alone. From now on, new code that is relying on less than ideal casting will complain and nudge me to improve it by warnings.

sspc: refactor to allow different transports 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.

We use EC_KEY pieces in vhost init... The apis are not removed but deprecated, we should have a way to keep trucking, but as it is the deprecation warning is promoted to an error. Let's add LWS_SUPPRESS_DEPRECATED_API_WARNINGS option off by default. If enabled at cmake, external deprecated api warnings are suppressed. This gives a general workaround for now for opensslv3. In addition, even if you don't do that, let's notice we are on openssl v3 and don't build the EC curve selection stuff, I don't think anyone is actually using it anyway.

asynchronous dns for ipv4 and ipv6 This adds the option to have lws do its own dns resolution on the event loop, without blocking. Existing implementations get the name resolution done by the libc, which is blocking. In the case you are opening client connections but need to carefully manage latency, another connection opening and doing the name resolution becomes a big problem. Currently it supports - ipv4 / A records - ipv6 / AAAA records - ipv4-over-ipv6 ::ffff:1.2.3.4 A record promotion for ipv6 - only one server supported over UDP :53 - nameserver discovery on linux, windows, freertos It also has some nice advantages - lws-style paranoid response parsing - random unique tid generation to increase difficulty of poisoning - it's really integrated with the lws event loop, it does not spawn threads or use the libc resolver, and of course no blocking at all - platform-specific server address capturing (from /etc/resolv.conf on linux, windows apis on windows) - it has LRU caching - piggybacking (multiple requests before the first completes go on a list on the first request, not spawn multiple requests) - observes TTL in cache - TTL and timeout use lws_sul timers on the event loop - ipv6 pieces only built if cmake LWS_IPV6 enabled

This adds an on-by-default cmake option and a couple of apis to also store and query "custom", ie, unknown-to-lws headers. A minimal example is also provided. At the moment it only works on h1, h2 support needs improvements to the hpack implementation. Since it bloats ah memory usage compared to without it if custom headers are present, the related code and ah footprint can be disabled with the cmake option LWS_WITH_CUSTOM_HEADERS, but it's on by default normally. ESP32 platform disables it. https://github.com/warmcat/libwebsockets/pull/1499

Logical DLOs are instantiated on heap and listed into an lws_display_list owner, DLOs handle attributes like position, bounding box, colour + opacity, and local error diffusion backing buffer. When the display list is complete, it can be rasterized a line at a time, with scoped error diffusion resolved, such that no allocation for the framebuffer is required at any point. DLOs are freed as the rasterization moves beyond their bounding box. Adds a platform registry binding names and other metadata to lws_display fonts / PNGs / JPEGs. Provides registration, destruction and best match selection apis.

http: add cmake option for header reduction defeat Lws now strips out http headers releated to h2, ws and unusual headers based on cmake config settings for those features... it saves some heap for the ah and reduces the table size in .rodata. It's possible code might have some external dependency on the original header indexes, but, eg, you don't enable h2 so those indexes are optimized with the h2 ones taken out. This introduces a cmake option "LWS_HTTP_HEADERS_ALL", default-OFF, that defeats the header table optimization for compatibility with older versions in the case the client software can't be adapted to use the lws-exported matching header enums. You probably don't need this.

Minilex is adapted to produce 8 different versions of the lex table, chosen at build-time according to which headers are included in the build. If you don't need the unusual headers, or aren't using h2 or ws, this chops down the size of the ah and the rodata needed to hold the parsing table from 87 strings / pointers to 49, and the parsing table from 1177 to 696 bytes.

lecp: add CBOR stream parser LECP like JSON LEJP This provides very memory-efficient CBOR stream parsing and writing. The parser converts pieces of CBOR into callbacks that define the structure and collate string and blobs into buffer chunks for extensible and easy access. It is fragementation-safe and does not need all the CBOR in the same place at one time, chunks of CBOR are parsed and discarded as provided. It does not allocate and just needs a few hundred bytes of stack for even huge CBOR objects. Huge strings and blobs are handled without needing memory to hold them atomically. Includes ./minimal-examples/api-tests/api-test-lecp that unit tests it against 82 official example CBORs and 26 additional test vectors from COSE (just checking the CBOR parsing). The writing apis allow printf style semantics with a variety of CBOR-aware %-formats. The apis write into a context that manages output buffer usage, if the output buffer fills, then the apis return with an AGAIN code that lets you issue and reset the output buffer and repeat the api all to issue more output. The subsequent calls can occur much later or from a different function context, so this is perfect for WRITEABLE-mediated output from the network parts of lws. See ./READMEs/README.cbor-lecp.md

lhp: Lightweight HTML Parser Introduce a very lightweight html5 + css2.1+ stateful stream parser, along the same lines as the lws json and cbor ones. This is interesting primarily because of just how low-resource it is for modest css + html, it uses an lwsac to hold the entirity of the css in memory at once but the html is parsed in chunks without any need to keep previous chunks around (chunks may be as small as 1 byte). A user callback receives element entry and exit callbacks with payload and all attributes parsed out, CSS related to the active element stack is parsed to provide a list of active css attributes, which takes heap for the duration of the parsing. In effect this provides rich information about the html and css state to the callback, which has the job of producing the layout in a user-defined way. As such, there is no DOM in memory at one time, there is only a stack of active elements like <html><body><div>xxx with their associated attributes (like class). So as it is, it does not support DOM modification such as JS changing elements after parsing, although elements with interesting IDs could be kept around by the callback. There is a corresponding tiny and relatively flat heap usage regardless of html size. Default CSS is specified as recommended in the CSS 2.1 standard. Inline <style></style> elements are supported, but not pre-html5 style= in element attributes, since these are incompatible with strict CSP. What the attributes should mean on your system, eg, font-size, font-family etc is left for the user callback to decide, along with how to lay out the items using the CSS attributes, and render them. Fixed point 32.32 constants are used (fraction expressed at parts in 100M) instead of floating point. If you have presentation needs, even on a constrained display on a constrained microcontroller, this makes it feasible to use standardized markup and styling instead of roll your own.

In addition, a new build-time option LWS_WITH_HTTP_UNCOMMON_HEADERS on by default allows removal of less-common http headers to shrink the parser footprint. Minilex is adapted to produce 8 different versions of the lex table, chosen at build-time according to which headers are included in the build. If you don't need the unusual headers, or aren't using h2 or ws, this chops down the size of the ah and the rodata needed to hold the parsing table from 87 strings / pointers to 49, and the parsing table from 1177 to 696 bytes.

roles: netlink This creates a role for RFC3549 Netlink monitoring. If the OS supports it (currently, linux) then each pt creates a wsi with the netlink role and dumps the current routing table at pt init. It then maintains a cache of the routing table in each pt. Upon routing table changes an SMD message is issued as an event, and Captive Portal Detection is triggered. All of the pt's current connections are reassessed for routability under the changed routing table, those that no longer have a valid route or gateway are closed.

lws-jpeg Introduce a rewritten picojpeg that is able to operate statefully and rasterize into an internal line ringbuffer, emitting a line of pixels at a time to the caller. This is the JPEG equivalent of the lws PNG decoder. JPEG is based around 8- or 16- line height MCU blocks, depending on the chroma coding, mandating a corresponding internal line buffer requirement. Example total heap requirement for various kinds of 600px width jpeg decoding: Grayscale: 6.5KB RGB 4:4:4: 16.4KB RGB 4:2:2v: 16.4KB RGB 4:4:2h: 31KB RGB 4:4:0: 31KB No other allocations occur during decode. Stateful stream parsing means decode can be paused for lack of input at any time and resumed seamlessly when more input becomes available.

client: rfc6724 dns results sorting RFC6724 defines an ipv6-centric DNS result sorting algorithm, that takes route and source address route information for the results given by the DNS resolution, and sorts them in order of preferability, which defines the order they should be tried in. If LWS_WITH_NETLINK, then lws takes care about collecting and monitoring the interface, route and source address information, and uses it to perform the RFC6724 sorting to re-sort the DNS before trying to make the connections.

Logical secure streams outlive any particular connection and supports "nailed-up" connectivity regardless of underlying connection stability.

upng: rewrite for stateful stream decode Add a rewritten version of upng that decodes statefully line by line, and so does not require a bitmap buffer for the output. This compares to original upng approach that needs heap allocations for the input, the whole output and intermediate allocations. Instead of buffers for input, decompression and output, it only allocates 2 x lines of RGBA pixels (ie, a few KB), and 32KB of decompressed data for backward references in the decoder, and decodes as needed into the 2-line buffer to produce line rasterized results. For a 600px width PNG, this is just 40KB heap for the duration.

event libs: default to building as dynamically loaded plugins Event lib support as it has been isn't scaling well, at the low level libevent and libev headers have a namespace conflict so they can't both be built into the same image, and at the distro level, binding all the event libs to libwebsockets.so makes a bloaty situation for packaging, lws will drag in all the event libs every time. This patch implements the plan discussed here https://github.com/warmcat/libwebsockets/issues/1980 and refactors the event lib support so they are built into isolated plugins and bound at runtime according to what the application says it wants to use. The event lib plugins can be packaged individually so that only the needed sets of support are installed (perhaps none of them if the user code is OK with the default poll() loop). And dependent user code can mark the specific event loop plugin package as required so pieces are added as needed. The eventlib-foreign example is also refactored to build the selected lib support isolated. A readme is added detailing the changes and how to use them. https://libwebsockets.org/git/libwebsockets/tree/READMEs/README.event-libs.md
