0.8.1 (2021-06-18)

Features:

• Exported new functions in C API to import the wasmedge_process module.
  • WasmEdge_ImportObjectCreateWasmEdgeProcess() can create and initialize the wasmedge_process import object.
  • WasmEdge_ImportObjectInitWasmEdgeProcess() can initialize the given wasmedge_process import object.
• Exported new AOT compiler configuration setting C APIs.
  • Users can set the options about AOT optimization level, dump IR, and instruction counting and cost measuring in execution after compilation to the AOT compiler through C APIs.
• Updated error codes according to the newest test suite of WebAssembly.
  • Applied the correct error message when trapping in the loading phase.
• Implemented the UTF-8 decoding in file manager.
• Implemented the basic name section parsing in custom sections.
• Added memory-mapped file helper, MMap for Linux.
  • Used mmap with MAP_NORESERVE for overcommited allocation.
  • Used MMap for file loading.
  • Merged FileMgr variants into one class.

Fixed issues:

• Applied the UTF-8 decoding.
  • Check the UTF-8 validation in custom sections, export sections, and import sections.
• Detected the redundant sections in modules.
  • Fixed this issue hence the sections rather than the custom section should be unique.
• Corrected the logging of data offset in the file while trap occurred in the loading phase.
  • Updated to the correct offset according to the refactored file manager.

Refactor:

• Updated manylinux* dockerfiles.
  • Upgraded gcc to 11.1.0.
  • Upgraded llvm to 12.0.0.
  • Upgraded boost to 1.76.
  • Moved environment variables to Dockerfile.
  • Used helper scripts to build.
• Moved the options of the AOT compiler into the Configure class.
• Refactor the file manager for supporting the Unexpected end loading malformed test cases.
  • Added the setSectionSize function to specify the reading boundary before the end of the file.
• Adjusted build scripts.
  • Set job pools for ninja generator.
  • Checked for newer compilers in std::filesystem.
  • Adjusted library dependency.

Documentations:

• Updated the WasmEdge ecosystem document.
  • Renamed the SSVM related projects into WasmEdge.

Tools:

• Updated the wasmedgec AOT compiler tool for API changes of the Configure.

Tests:

• Turn on the assert_malformed tests for WASM binary in spec tests.
  • Apply the interpreter tests.
  • Apply the AOT tests.
  • Apply the API tests.
• Updated the API unit tests for the new Configure APIs.
• Updated the AST and loader unit tests.
  • Added test cases of file manager to raise the coverage.
  • Added test cases of every AST node to raise the coverage.
