Wasmedge 0.10.0 release! New plug-in extension mechanism, socket API enhancement, llvm 14 support

stay 0.10.0 In the version ,WasmEdge New plug-ins are provided （plug-in） Mechanism , Make local extensions easier to develop and install , Improved and LLVM 14 The compatibility of , And support the new WebAssembly standard 、 Proposals and features .

• Local host A new plug-in system for the
• Yes WasmEdge socket API The enhancement of （ for example ,WasmEdge Microservices and Web Service client ）
• Support the new WebAssembly Proposals and specifications
• WasmEdge C API enhance
• Other features , And bug fixes

Local host A new plug-in system for the

host function Is allowed WebAssembly A bridge for programs to access the functions and features provided by local libraries . This is where we use more features and function extensions WebAssembly runtime The way . for example ,WASI The standard itself is passed host Function let WebAssembly Applications can use libc Make system calls .

WasmEdge Of TensorFlow、NN、Socket And image processing are extended through host Functionally implemented . Make it easy for developers to use host function , Yes WebAssembly runtime crucial .

new WasmEdge The plug-in system is designed to simplify host Function development and management . The plug-in system allows developers to use a unified host Function interfaces make it easy to create new WasmEdge Expand . see WasmEdge Book Guidelines in ： How to use WasmEdge Add to the plug-in system host function , Let's try .

At present, you can only use C++ To write WasmEdge plug-in unit . We will increase our understanding of Rust and C Support for .

WasmEdge Users of can now use the WasmEdge Add or remove a folder containing host Function to enable or disable WasmEdge Expand . The plug-in system allows users to easily 、 Safely manage the contributions of a large number of developers WasmEdge Expand .

for example , WasmEdge The team achieved wasmedge_process Extension as a plug-in .wasmedge_process allow WebAssembly Program calls operating system commands . The next few weeks , We will WasmEdge Migration of existing extensions to new plug-in formats . meanwhile , You are also welcome to WasmEdge Contribution based on host Function extension .

Wasi-socket promote

WasmEdge networking sockets yes non-blocking And high performance . WasmEdge It is the only one that can run Web Service application WebAssembly runtime. Many developers are trying to create and deploy software based on WasmEdge Of Web Service or client . In this release , We continue to improve for developers WasmEdge socket API.

• IPV4 and IPV6 Pattern
• UDP function ：send_to and resv_from
• DNS Name search
• Check socket Valid values for option enumeration
• correct ：MacOS Upper wasi-socket
• correct ： Use the same fd call poll_oneoff Twice and at socket On the call fd_close An error occurred when .
• ::getaddrinfo Zero terminated string of .

Looking forward to the future , We will Provide compatibility wasm Of Rust TLS Realization , To support HTTPS and stay WasmEdge Created in Tokio asynchronous runtime.

C API promote

C API yes WasmEdge Other languages API The basis of , for example WasmEdge Rust API and WasmEdge Go API. This version improves WasmEdge C API.

• take WasmEdge_ImportObjectContext Merge into WasmEdge_ModuleInstanceContext in .
• Use pointing to WasmEdge_FunctionInstanceContext And not FuncRef Index in value type .
• take WasmEdge_StoreContext The function of is moved to WasmEdge_ModuleInstanceContext.
• Updated WasmEdge_VMContext API.

This new version also brings new C API and Go API file . For those who want to use the update C and Go API For the developers , Please refer to WasmEdge Book.

standard Wasm Expand

WasmEdge The momentum is rapid , It's quite in line with WebAssembly standard , And supports all mandatory and optional WebAssembly standard . from 0.10.0 version ,WasmEdge Support Tail Call and extended-const The proposal .

Other features and bug fixes

In addition to the above characteristics , There are also some features to note .

• compatible LLVM 14, Improved performance .
• WasmEdge_VMContext、WasmEdge_ConfigureContext、WasmEdge_ModuleInstanceContext and WasmEdge_StoreContext APIs Thread safety in .
• AOT Mode of gas Limit , Allow in WasmEdge Precision metering applications in .
• New unit tests .
