0.7.3 (2021-01-22)

Features:

• Updated the easylogging++ to v9.97.0.
  • Disabled the file logging.
• Initial supported the WASI host functions for old system (CentOS 6).
  • Updated the WASI subscription insterface.
  • Used pipe for old GLIBC.
• Added supporting of subcommand in PO.
• Provided options to toggle white lists of ssvm_process in ssvm tool.
  • --allow-command COMMAND to add a command into white list in ssvm_process host functions.
  • --allow-command-all to allow all commands in ssvm_process host functions.
• Added the documentation of SSVM ecosystem.

Fixed issues:

• Fixed the loading issues in file manager.
  • Refined performance and added error handling in readBytes.
  • Fixed LEB128 and ULEB128 decoding and error codes.
• Fixed security issues of executing commands in ssvm_process host functions.
  • Managed a white list for command execution.

Refactor:

• Used vector of instance instead of std::unique_ptr in AST nodes.
• Merged all instruction node classes.
  • Added OpCode::Else instruction.
  • Serialized the instruction sequences. Move out the block body of If, Block, and Loop instructions.
• Applied the proposal configuration checking in the loader phase.
  • Moved the OpCode and value type validation of proposal configuration checking to loader phase.
  • Fixed the logging message.
  • Added helper functions to clean codes of logging.
• Refactored the validator for instruction serialization.
  • Removed the duplicated proposal configuration checking done at the loader phase.
  • Serialized the instruction iterating when validating.
• Refactored the Label in stack manager.
  • Label will record the from instruction iterator that causes entering this label.
  • Removed the next instruction getter in stack manager.
• Refactored the instruction iterating mechanism in interpreter.
  • Used the program counter to iterate and execute the instructions.
  • Merged all switch cases of OpCode.
• Moved out AOT related proxy codes and helper functions in interpreter to dependent files.

Tools:

• Added binfmt supporting for WASM interpreter.
  • Please use the tool tools/ssvm/ssvm-static with the same arguments as ssvm.
• Provided manylinux* support for legacy operatoring systems
  • manylinux1 is based on CentOS 5.9
  • manylinux2010 is based on CentOS 6
  • manylinux2014 is based on CentOS 7

Tests:

• Updated file manager tests for LEB128 and ULEB128 decoding.
• Updated AST tests for refactored AST nodes.
• Updated instruction tests for refactored instruction nodes.
• Added PO tests.
• Added ssvm_process tests.
