- Update ProcessMessage to accept method parameter for dynamic export invocation - Add method normalization (empty string defaults to 'poll') - Add proper error handling for unknown methods with stream reset - Update all test calls to include method parameter - Maintain backward compatibility with existing code
- Switch from SetStreamHandler to SetStreamHandlerMatch - Add protocol matching for both base protocol and method suffix - Extract method from protocol string (/ww/0.1.0/<proc-id>/<method>) - Update logging to include method information - Maintain backward compatibility for existing clients
- Change method from flag to positional argument (final argument) - Update ArgsUsage to <peer> <proc> [method] - Add argument validation for 2-3 arguments - Update protocol construction to include method suffix when specified - Enhance connection banner to show method being used - Update examples in help text
- Change exported function from 'poll' to 'echo' - Update function name and comments accordingly - This demonstrates the named export functionality
- Rebuild main.wasm with updated echo export function - Binary now exports 'echo' instead of 'poll' function
- Update tests to use 'echo' function instead of 'poll' to match WASM module exports - Add Reset() expectations to mock streams to handle function not found cases - Fix TestProc_Integration_WithRealWasm, TestProc_Poll_WithGomock, TestEcho_Asynchronous, and TestEcho_RepeatedAsync - All tests now pass successfully
- Add system/ipfs.go with complete fs.FS interface implementation - Add system/ipfs_test.go with comprehensive test coverage - Support directory traversal, file reading, and sub-filesystem creation - Integrate with IPFS UnixFS for distributed file access - Add github.com/pkg/errors dependency for error handling This restores the IPFS filesystem functionality that was previously removed, enabling guest filesystem access to IPFS content.
