v0.11.0

0.11.0 (2023/03/27)

• In this version, Wasm modules can now return any output type via stdout, including binaries with non UTF-8 bytes sequences or \0 NULL terminators in the middle.
• Also added some minor improvements for error management and building scripts.

mod_wasm.so

• Support for the new wasm_executionctx_run() signature in the wasm_runtime C-API.
• Better error management when invoking ap_scan_script_header_err_strs().
• Some improvements in build.sh per #36.

libwasm_runtime.so

• Now the Wasm module stdout is modelled as a Vec<u8> instead of a String:
  • This prevents an exception when a module emits a non UTF-8 output.
• New signature for wasm_executionctx_run() in the C-API now requires buffer and length pointers:
  • This allows NULL terminators (\0) in the middle of the output to be managed by C without truncating the string (ie.: requires fwrite() instead of fprintf(), etc.).
• Better clean_all target in Makefile.
• Dependencies:
  • Bump version dependencies:
    • wasmtime to 7.0.0.
    • anyhow to 1.0.70.
  • Updated cargo.lock dependencies via cargo update.

httpd-mod-wasm demo container

• Enabling mod_rewrite.
• Adding /php-hello-slim demo.
• Adding WasmEnv TMPDIR /tmp directive to all PHP-related demos.
• Adding stubs for Drupal and Drupal-Zero demos (still WIP).
