Features:

  • Supported the WASM tail-call proposal.
    • Added the WasmEdge_Proposal_TailCall for the configuration in WasmEdge C API.
    • Users can use the --enable-tail-call to enable the proposal in wasmedge and wasmedgec tools.
  • Supported the WASM extended-const proposal.
    • Added the WasmEdge_Proposal_ExtendedConst for the configuration in WasmEdge C API.
    • Users can use the --enable-extended-const to enable the proposal in wasmedge and wasmedgec tools.
  • Supported thread-safe in WasmEdge_VMContext, WasmEdge_ConfigureContext, WasmEdge_ModuleInstanceContext, and WasmEdge_StoreContext APIs.
  • Supported the gas limit in AOT mode.
  • New supporting of the wasi-socket proposal.
    • Supported send_to.
    • Supported resv_from.
  • Plugin support
    • Add loadable plugin support.
    • Move wasmedge_process to a loadable plugin.

Fixed issues:

  • Fixed wasi-socket proposal issues.
    • Fixed wasi-socket on MacOS.
    • Fixed error when calling poll_oneoff with the same fd twice.
    • Fixed error when calling fd_close on socket.
    • Forged zero-terminated string for ::getaddrinfo.
    • Checked the socket options enumeration for valid value.
  • Fixed the statistics enable/disable routine.
  • Fixed the output format by the file extension name detection on multiple platforms.

Known issues:

  • Universal WASM format failed on MacOS platforms.
    • In current status, the universal WASM format output of the AOT compiler on MacOS platforms will cause bus error when execution.
    • We are trying to fix this issue. For working around, please use the shared library format output of the AOT mode.
    • Developers can specify the extension name as .dylib on MacOS, .so on Linux, and .dll on Windows for the shared library format output of the AOT compiler.

Refactor:

  • Supported multi-thread execution.
    • Changed the StackManager in Executor as thread local to support the multi-thread.
    • Used atomic operations for cost measuring.
    • Supported multi-thread timer.
  • Refactored the enumerations.
    • Replaced the std::unordered_map of the enumeration strings with DenseMap and SpareMap.
    • Merged the both C and C++ enumeration definitions into the enum.inc file.
    • Updated the ErrCode enumeration for the newest spec tests.
  • Refactored the code architecture for supporting tail-call proposal.
    • Split the call_indirect execution routine in compiler into AOT and interpreter path.
    • Updated the pop frame mechanism in the StackManager.
    • Updated the enter function mechanism.
  • Refined the file manager in Loader.
    • Supported the offset seeking in file and buffer.
    • Skipped the instructions parsing in AOT mode for better loading performance.
  • Refined the branch mechanism in the StackManager for better performance in the interpreter mode.
    • Pre-calculated the stack offset for branch in the validation phase.
    • Removed the label stack in the StackManager and used the pre-calculated data for branch.
    • Removed the dummy frame mechanism in the StackManager.
  • Supplied the pointer-based retrieving mechanism in the StoreManager and ModuleInstance.
    • Removed the address mechanism for instances in the StoreManager.
    • Added the unsafe getter functions for the instances.
  • Refactored the StoreManager, ModuleInstance, and Executor.
    • Used the ModuleInstance-based resource management instead of StoreManager-based.
    • Moved the ownership of instances from the StoreManager into the ModuleInstance.
    • Merged the ImportObject into the ModuleInstance.
    • Invoking functions by FunctionInstance rather than the function name in Executor.

Documentations:

Tests:

  • Updated the spec tests to the date 20220504.
  • Added the spec tests for the tail-call proposal.
  • Added the mixed invocation tests between interpreter mode and AOT mode WASM functions.
  • Added the thread-safe and multi-thread execution tests.
  • Added wasi-socket tests for poll_oneoff, send_to, and recv_from.

Thank all the contributors that made this release possible!
