The `writeToCoderOutputChannel` method exists in the Storage class alongside file system operations, secret management, and other unrelated functionality. This makes it difficult to: + +- **Debug user-reported issues**: When users report bugs, especially client connection issues that don't reproduce locally, there's no consistent way to enable detailed logging to help diagnose the problem +- **Centralize logging logic**: Logging is tied to the Storage class, which also manages secrets, URLs, CLI binaries, and file operations - a clear violation of single responsibility +- **Control verbosity**: Users can't easily enable debug-level logging when needed without modifying code +- **Standardize output**: While `writeToCoderOutputChannel` adds timestamps, other parts use direct `output.appendLine` calls +- **Expand debugging capabilities**: Adding new diagnostic logging for specific subsystems (like client connections) requires passing the Storage instance around +- **Maintain separation of concerns**: The Storage class has become a "god object" that handles too many responsibilities + +## Success Criteria + +1. **Centralized Logging**: All log output goes through a single adapter +2. **Log Levels**: Support for `debug` and `info` levels + - Additional levels can be added in future iterations +3. **Type Safety**: Fully typed TypeScript implementation + - No `any` types in the logger module or modified files + - No `@ts-ignore` or `eslint-disable` comments + - All types explicitly defined or properly inferred +4. **Testable**: + - Unit tests use `ArrayAdapter` for fast, isolated testing + - ArrayAdapter provides immutable snapshots via `getSnapshot()` to prevent test interference + - Integration tests use `OutputChannelAdapter` to verify VS Code integration + - Test isolation for concurrent test suites: + - `setAdapter()` throws if adapter already set (prevents test conflicts) + - `withAdapter()` provides safe temporary adapter swapping with automatic revert + - Ideal for Vitest's concurrent test execution + - `reset()` and `setAdapter()` methods restricted to test environment (NODE_ENV === 'test') + - `reset()` properly disposes of configuration change listeners to prevent memory leaks + - Methods throw error if called in production for safety +5. **Performance**: Minimal overhead for logging operations + - Measured relative to a no-op adapter baseline + - Debug calls when disabled: < 10% overhead vs no-op + - Debug calls when enabled: < 10x overhead vs no-op (including formatting) + - Info calls: < 5x overhead vs no-op + - Measurement methodology: + - Use `performance.now()` from Node's `perf_hooks` + - Compare against `NoOpAdapter` that does nothing + - Run 10,000 iterations, discard outliers, use median + - CI passes if within percentage thresholds (not absolute times) +6. **Fault Tolerance**: Logger never throws exceptions + - Silently swallows OutputChannel errors (e.g., disposed channel on reload) + - Logging failures must not crash the extension + - No error propagation from the logging subsystem + - Accepts that OutputChannel writes may interleave under concurrent access +7. **Live Configuration**: Monitor `coder.verbose` setting changes without requiring extension restart + - Supports workspace, folder, and global configuration levels + - Uses the most specific configuration available + +## Scope & Constraints + +### In Scope +- Extract logging functionality from the Storage class into a dedicated logging adapter +- Create a logging adapter/service with support for debug and info levels +- Convert all existing `writeToCoderOutputChannel` and `output.appendLine` calls to use the adapter +- Maintain integration with VS Code's OutputChannel ("Coder") + - OutputChannel is created in `extension.ts` and passed to both Logger and Storage + - Logger uses it for logging via OutputChannelAdapter + - Storage continues to use it for progress reporting (e.g., binary downloads) +- Provide a simple API for logging (e.g., `logger.debug("message")`, `logger.info("message")`) + - Callers only provide the message content, not formatting + - Only string messages accepted (no automatic object serialization) + - Callers must stringify objects/errors before logging (e.g., using template literals) +- Allow runtime configuration of log levels +- Handle all formatting (timestamps, level tags, etc.) within the logger +- Remove only the `writeToCoderOutputChannel` method from Storage class + +### Out of Scope +- External logging services integration (future enhancement) +- File-based logging (all logs go to VS Code OutputChannel) +- Log file rotation or persistence +- Structured logging formats (JSON, etc.) +- Performance metrics or telemetry +- Custom UI for viewing logs (uses VS Code's built-in OutputChannel UI) +- Synchronization of concurrent writes (OutputChannel writes may interleave) +- Automatic object/error serialization (callers must convert to strings) + +## Technical Considerations + +### Architecture +- Singleton pattern for the logger instance +- Interface-based design with pluggable adapters: + - `LogAdapter` interface for output handling + - `OutputChannelAdapter` for VS Code OutputChannel integration + - `ArrayAdapter` for testing (stores logs in memory) +- OutputChannel ownership and lifecycle: + - Created once in `extension.ts` activate method + - Passed to OutputChannelAdapter constructor + - Also passed to Storage for non-logging uses (progress reporting) + - Single channel shared between Logger and Storage + - Note: VS Code OutputChannel is async; concurrent writes may interleave + - This is acceptable for debugging/diagnostic purposes + - In browser/web extensions, OutputChannel maps to in-memory buffer (no file I/O) +- Configuration through VS Code settings: + - `coder.verbose`: boolean setting to enable debug logging (default: false) + - When true: shows debug level logs + - When false: shows info level and above only + - Respects workspace folder-specific settings (uses most specific configuration) +- Configuration monitoring using `vscode.workspace.onDidChangeConfiguration` + - Only responds to changes in `coder.verbose` specifically + - Ignores all other configuration changes to avoid unnecessary processing + - Updates when workspace folders are added/removed or active editor changes +- **Centralized formatting**: All log formatting (timestamps, level tags, source location) happens within the logger implementation, not at call sites + +### API Design +```typescript +interface LogAdapter { + write(message: string): void + clear(): void +} + +interface Logger { + log(message: string, severity?: LogLevel): void // Core method, defaults to INFO + debug(message: string): void // String only -

Create the logger module at `src/logger.ts` with: + - Singleton pattern implementation + - LogAdapter interface and implementations (OutputChannelAdapter, ArrayAdapter) + - Logger initialization accepts OutputChannel (not created internally) + - Configuration reading from VS Code settings (`coder.verbose`) + - Use `workspace.getConfiguration()` to respect folder-specific settings + - Configuration change listener using `workspace.onDidChangeConfiguration` + - Filter to only handle `coder.verbose` changes using `affectsConfiguration()` + - Re-read configuration on folder/editor changes to respect local settings + - Timestamp formatting in UTC ISO-8601 (using `new Date().toISOString()`) and level prefixes + - Debug mode with source location tracking (file/line info) + - Gracefully handle empty `Error().stack` in browser environments + - Test method guards: `reset()` and `setAdapter()` check `process.env.NODE_ENV === 'test'` + - `setAdapter()` throws if adapter already installed (prevents concurrent test conflicts) + - `withAdapter()` implementation: + ```typescript + withAdapter(adapter: LogAdapter, fn: () => T): T { + const previous = this.adapter + this.adapter = adapter + try { + return fn() + } finally { + this.adapter = previous + } + } + ``` + - `reset()` implementation must dispose configuration listener to prevent memory leaks +2. Create comprehensive tests at `src/logger.test.ts`: + - Unit tests using ArrayAdapter for logic testing + - Separate integration tests for OutputChannelAdapter + - Performance benchmarks: + - Create NoOpAdapter as baseline + - Measure relative performance using `performance.now()` + - Ensure overhead stays within specified percentages + - Test both cold and warm paths +3. Update `extension.ts`: + - Create OutputChannel in activate method + - Initialize Logger with OutputChannel via OutputChannelAdapter + - Continue passing OutputChannel to Storage (for progress reporting) +4.

The `writeToCoderOutputChannel` method exists in the Storage class alongside file system operations, secret management, and other unrelated functionality. This makes it difficult to: - -- **Debug user-reported issues**: When users report bugs, especially client connection issues that don't reproduce locally, there's no consistent way to enable detailed logging to help diagnose the problem -- **Centralize logging logic**: Logging is tied to the Storage class, which also manages secrets, URLs, CLI binaries, and file operations - a clear violation of single responsibility -- **Control verbosity**: Users can't easily enable debug-level logging when needed without modifying code -- **Standardize output**: While `writeToCoderOutputChannel` adds timestamps, other parts use direct `output.appendLine` calls -- **Expand debugging capabilities**: Adding new diagnostic logging for specific subsystems (like client connections) requires passing the Storage instance around -- **Maintain separation of concerns**: The Storage class has become a "god object" that handles too many responsibilities - -## Success Criteria - -1. **Centralized Logging**: All log output goes through a single adapter -2. **Log Levels**: Support for `debug` and `info` levels - - Additional levels can be added in future iterations -3. **Type Safety**: Fully typed TypeScript implementation - - No `any` types in the logger module or modified files - - No `@ts-ignore` or `eslint-disable` comments - - All types explicitly defined or properly inferred -4. **Testable**: - - Unit tests use `ArrayAdapter` for fast, isolated testing - - ArrayAdapter provides immutable snapshots via `getSnapshot()` to prevent test interference - - Integration tests use `OutputChannelAdapter` to verify VS Code integration - - Test isolation for concurrent test suites: - - `setAdapter()` throws if adapter already set (prevents test conflicts) - - `withAdapter()` provides safe temporary adapter swapping with automatic revert - - Ideal for Vitest's concurrent test execution - - `reset()` and `setAdapter()` methods restricted to test environment (NODE_ENV === 'test') - - `reset()` properly disposes of configuration change listeners to prevent memory leaks - - Methods throw error if called in production for safety -5. **Performance**: Minimal overhead for logging operations - - Measured relative to a no-op adapter baseline - - Debug calls when disabled: < 10% overhead vs no-op - - Debug calls when enabled: < 10x overhead vs no-op (including formatting) - - Info calls: < 5x overhead vs no-op - - Measurement methodology: - - Use `performance.now()` from Node's `perf_hooks` - - Compare against `NoOpAdapter` that does nothing - - Run 10,000 iterations, discard outliers, use median - - CI passes if within percentage thresholds (not absolute times) -6. **Fault Tolerance**: Logger never throws exceptions - - Silently swallows OutputChannel errors (e.g., disposed channel on reload) - - Logging failures must not crash the extension - - No error propagation from the logging subsystem - - Accepts that OutputChannel writes may interleave under concurrent access -7. **Live Configuration**: Monitor `coder.verbose` setting changes without requiring extension restart - - Supports workspace, folder, and global configuration levels - - Uses the most specific configuration available - -## Scope & Constraints - -### In Scope - -- Extract logging functionality from the Storage class into a dedicated logging adapter -- Create a logging adapter/service with support for debug and info levels -- Convert all existing `writeToCoderOutputChannel` and `output.appendLine` calls to use the adapter -- Maintain integration with VS Code's OutputChannel ("Coder") - - OutputChannel is created in `extension.ts` and passed to both Logger and Storage - - Logger uses it for logging via OutputChannelAdapter - - Storage continues to use it for progress reporting (e.g., binary downloads) -- Provide a simple API for logging (e.g., `logger.debug("message")`, `logger.info("message")`) - - Callers only provide the message content, not formatting - - Only string messages accepted (no automatic object serialization) - - Callers must stringify objects/errors before logging (e.g., using template literals) -- Allow runtime configuration of log levels -- Handle all formatting (timestamps, level tags, etc.) within the logger -- Remove only the `writeToCoderOutputChannel` method from Storage class - -### Out of Scope - -- External logging services integration (future enhancement) -- File-based logging (all logs go to VS Code OutputChannel) -- Log file rotation or persistence -- Structured logging formats (JSON, etc.) -- Performance metrics or telemetry -- Custom UI for viewing logs (uses VS Code's built-in OutputChannel UI) -- Synchronization of concurrent writes (OutputChannel writes may interleave) -- Automatic object/error serialization (callers must convert to strings) - -## Technical Considerations - -### Architecture - -- Singleton pattern for the logger instance -- Interface-based design with pluggable adapters: - - `LogAdapter` interface for output handling - - `OutputChannelAdapter` for VS Code OutputChannel integration - - `ArrayAdapter` for testing (stores logs in memory) -- OutputChannel ownership and lifecycle: - - Created once in `extension.ts` activate method - - Passed to OutputChannelAdapter constructor - - Also passed to Storage for non-logging uses (progress reporting) - - Single channel shared between Logger and Storage - - Note: VS Code OutputChannel is async; concurrent writes may interleave - - This is acceptable for debugging/diagnostic purposes - - In browser/web extensions, OutputChannel maps to in-memory buffer (no file I/O) -- Configuration through VS Code settings: - - `coder.verbose`: boolean setting to enable debug logging (default: false) - - When true: shows debug level logs - - When false: shows info level and above only - - Respects workspace folder-specific settings (uses most specific configuration) -- Configuration monitoring using `vscode.workspace.onDidChangeConfiguration` - - Only responds to changes in `coder.verbose` specifically - - Ignores all other configuration changes to avoid unnecessary processing - - Updates when workspace folders are added/removed or active editor changes -- **Centralized formatting**: All log formatting (timestamps, level tags, source location) happens within the logger implementation, not at call sites -

-### Implementation Plan - -1. Create the logger module at `src/logger.ts` with: - - Singleton pattern implementation - - LogAdapter interface and implementations (OutputChannelAdapter, ArrayAdapter) - - Logger initialization accepts OutputChannel (not created internally) - - Configuration reading from VS Code settings (`coder.verbose`) - - Use `workspace.getConfiguration()` to respect folder-specific settings - - Configuration change listener using `workspace.onDidChangeConfiguration` - - Filter to only handle `coder.verbose` changes using `affectsConfiguration()` - - Re-read configuration on folder/editor changes to respect local settings - - Timestamp formatting in UTC ISO-8601 (using `new Date().toISOString()`) and level prefixes - - Debug mode with source location tracking (file/line info) - - Gracefully handle empty `Error().stack` in browser environments - - Test method guards: `reset()` and `setAdapter()` check `process.env.NODE_ENV === 'test'` - - `setAdapter()` throws if adapter already installed (prevents concurrent test conflicts) - - `withAdapter()` implementation: - ```typescript - withAdapter(adapter: LogAdapter, fn: () => T): T { - const previous = this.adapter - this.adapter = adapter - try { - return fn() - } finally { - this.adapter = previous - } - } - ``` - - `reset()` implementation must dispose configuration listener to prevent memory leaks -2. Create comprehensive tests at `src/logger.test.ts`: - - Unit tests using ArrayAdapter for logic testing - - Separate integration tests for OutputChannelAdapter - - Performance benchmarks: - - Create NoOpAdapter as baseline - - Measure relative performance using `performance.now()` - - Ensure overhead stays within specified percentages - - Test both cold and warm paths -3. Update `extension.ts`: - - Create OutputChannel in activate method - - Initialize Logger with OutputChannel via OutputChannelAdapter - - Continue passing OutputChannel to Storage (for progress reporting) -4. Extract and refactor the existing `writeToCoderOutputChannel` logic from Storage class -5. Remove ONLY the `writeToCoderOutputChannel` method from Storage (keep OutputChannel for other uses) -6. Systematically replace each `writeToCoderOutputChannel` call with appropriate logger methods -7. For `output.appendLine` calls in Storage, evaluate each: - - Logging messages → convert to logger calls - - Progress/status messages → keep as direct OutputChannel calls -8. Verify functionality with existing tests -9.
