2023-08-28API-C.md: Fix a broken fragment linkAndrew Clayton1-1/+1
Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-28API-Rust.md: Add a Rust 'rusty' API documentAndrew Clayton1-0/+885
This was done by 'cp API-C.md API-Rust.md' and then adjusted as necessary. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-28Rust/rusty: Make a bunch of functions take ctx as constAndrew Clayton1-8/+8
The various uwr_get_ functions should take the context pointer as a const. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-28libunit-wasm: Pass ctx into luw_http_hdr_get_value() as constAndrew Clayton4-5/+6
Technically the context pointer can be passed in const even though we then un-const it passing it to the luw_foreach_http_hdr() macro. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-28libunit-wasm: Remove the idx argument from luw_http_add_header()Andrew Clayton8-19/+28
This was used to specify the index of the response header being added, starting at 0 and incrementing by one for each header. Instead of having the programmer specify this, track it internally. We add an extra check in luw_http_add_header() to make sure we aren't trying to add more headers than we said with luw_http_init_headers(), if we are, simply return. This updates the API-C.md and the various examples and 'rusty' API wrapper. Suggested-by: Liam Crilly <liam@nginx.com> Signed-off-by: Andrew Clayton <a.clayton@nginx.com>

2023-08-26README.md: Significant re-workingAndrew Clayton1-115/+141
This adds a new 'Setup a Suitable Environment' section that replaces the 'Getting Started' section and it's subsections. This provides a more comprehensive guide to setting up a suitable environment on some specific systems (currently Fedora/CentOS/RHEL etc & Debian/Ubuntu).

2023-08-26github/workflows: Simplify installation of libclang_rt.builtins-wasm32.aAndrew Clayton1-1/+1
Rather than using and rpm(8) and grep(1) to find the location to store the libclang_rt.builtins-wasm32.a file use clangs -print-runtime-dir option and strip the last component. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>

2023-08-26libunit-wasm: Fix rust buildAndrew Clayton3-3/+3
The rust build failed when trying to publish new crates, although for some reason it didn't fail before that, due to the luw_srb_flags_t enums generated by bindgen being 32 bit unsigned integers and the flags argument to luw_set_req_buf() being an unsigned long (which is 64 bits on my system) and thus producing a type mismatch error. Rather than fight with rust just make the flags argument an unsigned int, 32 bits is more than enough for this anyway. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-26Rust/unit-wasm-sys: Don't require the wasi-sysrootAndrew Clayton1-3/+0
When I added the luw_http_hdr_get_value() function I needed to include strings.h, unfortunately I added it to unit-wasm.h instead of libunit-wasm.c This then meant that we needed to point bindgen/clang, for generating the bindings, to the wasi-sysroot for the strings.h file. I guess this is a system dependant include or something and when we use the wasm32-wasi target in clang it uses a paired down include search path list, none of which have strings.h This then had the knock on effect of requiring to inform cargo build of the wasi-sysroot path. Now that we put strings.h in the right place, we don't need the wasi-sysroot when building the rust stuff. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-26libunit-wasm: Include strings.h in the right fileAndrew Clayton2-1/+1
When I added the luw_http_hdr_get_value() function I needed to include strings.h, unfortunately I added it to unit-wasm.h instead of libunit-wasm.c This had the undesirable effect of requiring the wasi-sysroot when building the rust stuff for generating the libunit-wasm rust bindings. By including strings.h in the right file we get rid of that requirement which a subsequent commit will take care of. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-26Rust/unit-wasm-sys: Remove reference to wrapper.h from build.rsAndrew Clayton1-1/+0
There is no wrapper.h in the repository. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>

This in preparation for some upcoming changes. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-25README.md: Update the README and config exampleAndrew Clayton2-15/+15
This takes into account the recent porting of the Rust demo applications to the new 'rusty' wrappers. The updates relate to the function handler names, the ones provided by the application now use the uwr_ prefix, the malloc and free handlers are still using the luw_ prefix as the applications aren't providing their own versions of those, the ones from libunit-wasm will be used. This is a useful demonstration of a number of things, but ultimately that you can call these handlers anything you want. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-25Rust: Port the Rust Wasm demos to the new 'rusty' wrappersAndrew Clayton2-239/+137
rusty is a thin wrapper over the generated libunit-wasm bindings to provide a more native rust like interface. This gets rid of all the casting and ugly string handling. It massively reduces the amount of unsafe {} blocks needed, though some still are... All in all this provides a nice code cleanup. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-25Rust: Add a nicer wrapper around the libunit-wasm bindingsAndrew Clayton5-0/+225
This adds a nice wrapper (aka rusty) around the generated libunit-wasm bindings. This should provide a more native rust like experience with the following benefits - No casting. So no things like 'as *mut c_void' - Native rust strings. So no things like '.as_ptr() as *const c_char' - Better ctx initialisation. Filed initialisation is now hidden away - Great reduction in the amount of unsafe {} blocks required - Generally more compact There are also some new macros - C2S!() converts a CStr to a Str - S2C!() converts a formatted Str to a Cstr using format!() - uwr_write_str!() a wrapper around luw_mem_writep_data and format!() This wrapper uses a uwr (Unit Wasm Rust) prefix under a 'rusty' namespace. The luw_http_hdr_iter() function proved tricky to wrap and the callback function still takes C style arguments due to the fact that this function is called from the libunit-wasm C library. The provided wrapper simply means we can use this without having to use an unsafe {} block around it in application code. Similarly with other functions that technically didn't need to be wrapped, wrapping them means that the unsafe {} blocks are hidden away. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>

2023-08-25Rust/unit-wasm-sys: Bump the version of the crateAndrew Clayton2-2/+2
unit-wasm-sys 0.1.2 Might as well do this now before the code changes and we bump the version again. This version was published to crates.io Signed-off-by: Andrew Clayton <a.clayton@nginx.com>

2023-08-24libunit-wasm: Put LUW_SRB_FLAGS_ALL in the enumAndrew Clayton2-4/+6
No reason why this needed to be a separate #define. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-23github/workflows: No need to download the wasi-sysrootAndrew Clayton1-3/+2
The wasi-sysroot is now packaged by Fedora in the wasi-libc-devel & wasi-libc-static packages (just installing wasi-libc-devel should bring in the other if needed). We also no longer need bindgen-cli as we are building the rust stuff from within the build.rs files. Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
2023-08-23shared.mk: Ensure WASI_SYSROOT is exported to the environmentAndrew Clayton1-0/+2
If you don't have WASI_SYSROOT set in the shell and you don't specify it in the make command, then make will try and find the wasi-sysroot in some known locations and then set the WASI_SYSROOT accordingly. However in this case (no shell variable and not specified in the make command) then when it comes to building the rust stuff, cargo build fails when trying to generate the bindings as it needs the wasi-sysroot but doesn't pick it up from the shell environment. Fix this by exporting WASI_SYSROOT from shared.mk Signed-off-by: Andrew Clayton <a.clayton@nginx.com>
