Middle-out truncation is a really great feature and it should still be implemented, however it unnecessarily interferes with #1365 because it hooked into the low-level chunk management that comes directly from VSCE shell integration. The best place to hook OutputBuilder is as follows depending on the state of terminal interaction: 1. Foreground terminals: Cline.ts: executeCommandTool(...) { process.on("line", (line) => { lines.push(line) ... } } 2. For background terminals: hook in at the point that getUnretrievedOutput is consumed for active or inactive terminals in Cline.ts:getEnvironmentDetails() Please note: The Terminal classes are very sensitive to change, partially because of the complicated way that shell integration works with VSCE, and partially because of the way that Cline interacts with the Terminal* class abstractions that make VSCE shell integration easier to work with. At the point that PR#1365 is merged, it is unlikely that any Terminal* classes will need to be modified substantially. Generally speaking, we should think of this is a stable interface and minimize changes.

testing This commit combines three related improvements to terminal testing: - Create a reusable function for testing terminal commands with real output - Update tests to properly invoke terminal shell execution handlers - Add microsecond timing to measure execution performance Key improvements: - Added testTerminalCommand function that takes command and expected output - Use child_process.execSync to run real commands and feed output into mock terminal stream - Properly trigger VSCode onDidStartTerminalShellExecution and onDidEndTerminalShellExecution events - Add timeout mechanism to prevent hanging tests - Measure execution time from terminal process creation to command completion - Display both microseconds and milliseconds in test output - Add test for base64 encoded zeros with configurable line count - Increase buffer size for execSync to handle large outputs - Limit output display to avoid cluttering the terminal Signed-off-by: Eric Wheeler ---

This improves code organization and encapsulation by centralizing terminal-related functionality. The change establishes a clearer object model for terminal management, setting the foundation for a more maintainable terminal architecture. All references throughout the codebase have been updated to use the new Terminal class while preserving existing functionality. Tests have been updated and verified to ensure compatibility with the new structure.

The method is responsible for translating exit codes into detailed results, including signal information. Changes include: - Moved interpretExitCode method to TerminalProcess class - Updated imports in TerminalManager and Cline to reference ExitCodeDetails from TerminalProcess - Added findTerminalIdByVscodeTerminal helper method in TerminalManager - Added comprehensive unit tests for interpretExitCode in TerminalProcess - Tests cover undefined exit codes, normal exit codes (0-127), and signal exit codes (128+) This change improves code organization by placing the exit code interpretation logic closer to where it's primarily used, in the TerminalProcess class.

This change centralizes terminal management in TerminalRegistry and eliminates duplicate state tracking in TerminalManager. The hierarchy flows from TerminalRegistry (managing all terminals) to Terminal (encapsulating a terminal instance) to TerminalProcess (running within a terminal). Key changes: - Remove `processes` map from TerminalManager - Add static getUnretrievedOutput and isProcessHot methods to TerminalRegistry, which manages all terminals globally Test updates: - Modify test setup to create Terminal instances -

Terminal selection now follows a priority order: 1. First try to find a terminal already assigned to this task with matching directory 2. If not found, try to find any available terminal with matching directory 3. If still not found, try to find any non-busy terminal 4. Only create a new terminal as a last resort When a task ends, all terminals associated with it are released for use by other tasks. This prevents the issue where multiple Roo task instances could inadvertently share terminals, which could lead to confusion when terminal output from one task appears in another task's context.

This caused issues with capturing output from subsequent commands, particularly with custom shell prompts. Instead of forcing directory changes, we now track terminal state through shell integration with a fallback mechanism, and provide explicit working directory feedback to the model. This allows terminals to maintain their natural state while ensuring accurate command output capture. Changes: - Remove forced `cd` commands that were disrupting terminal state - Add getCurrentWorkingDirectory() method with shell integration fallback - Add customCwd parameter to executeCommandTool for flexible directory handling - Add requiredCwd parameter to control terminal selection behavior - Refactor terminal selection logic for more consistent state management - Modify environment details to include terminal working directory feedback - Update XML schema to include optional working directory parameter in execute_command The environment details now provide explicit feedback about terminal state: Command executed in terminal N from '/path/to/dir'.

The fix allows background terminals (taskId undefined) to act as broadcast sources that can update any task through getEnvironmentDetails, while still maintaining proper isolation for task-specific terminals. This enables common workflows where: 1. A task launches a background compiler 2. That task is closed and a new task is started 3.
