2026-01-29	refactor: improve Go best practices compliance	Paul Buetow
	- Add explicit interface satisfaction checks (var _ Interface = (*Type)(nil)) for compile-time verification: - TurboWriter implementations (DirectTurboWriter, TurboChannelWriter) - Processor implementations (GrepLineProcessor, ChannellessLineProcessor) - Parser implementations (genericParser, csvParser, genericKVParser, custom parsers, mimecastParser) - Logger implementations (file, stdout) - Handler implementations (ServerHandler, ClientHandler) - Connector implementations (Serverless, ServerConnection) - SSH callback implementations (KnownHostsCallback) - Improve error handling with context wrapping (%w): - SSH operations: GeneratePrivateRSAKey, Agent - Query parsing: Query.parse - SSH client connections: dial, session, handle methods - Fix receiver consistency: - Convert Query.String() from value to pointer receiver - Convert Outfile.String() from value to pointer receiver - Convert all KnownHostsCallback methods to pointer receivers - Convert mapCommand.Start() to pointer receiver - Reorganize file structure for better clarity: - internal/io/dlog/dlog.go: Move type definition before public functions - internal/mapr/token.go: Reorganize helper functions after public ones - Add documentation comments: - Query.String() method - Outfile.String() method - Regex.String() method - Improve config variable documentation All unit tests and integration tests pass.

2025-06-28	feat: implement channel-less grep for 62% performance improvement	Paul Buetow
	- Add LineProcessor interface for direct line processing without channels - Implement channel-less file reading in readfile_processor.go - Add optimized reader with 256KB buffering for efficient I/O - Create GrepLineProcessor for direct writing without intermediate channels - Fix serverless mode hanging due to stdin pipe detection - Fix base64 decoding bug (was counting characters instead of arguments) - Fix message output formatting by adding proper newline handling Performance improvements: - Channel-based: 9.00s → Channel-less: 3.42s (62% faster on 100MB files) - Removed channel synchronization overhead and context switching - Reduced memory allocations with buffer pooling Environment variables: - DTAIL_CHANNELLESS_GREP=yes - Enable channel-less implementation - DTAIL_OPTIMIZED_READER=yes - Use optimized buffered reader Known limitation: Inverted grep with context (--invert with --before/--after) not fully implemented in channel-less mode. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
