Summary of Changes

Hello @gemini-cli-robot, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a critical fix to the ShellExecutionService to enhance its handling of terminal output, particularly concerning long and wrapped lines. The changes ensure that the service accurately captures and presents output without losing data due to incorrect trimming or wrapping, thereby improving the reliability of shell command execution results. This is an automated cherry-pick to patch an existing stable release.

Highlights

  • Improved Terminal Output Handling: The ShellExecutionService now correctly processes wrapped lines from the terminal buffer, preventing unintended trimming of significant trailing spaces and ensuring that long lines are not incorrectly wrapped in the final output.
  • New Test Case for Long Lines: A new test has been added to shellExecutionService.test.ts to specifically verify that the service does not wrap long lines in the final output, even when the configured terminal width is narrow.

Code Review

This pull request cherry-picks a fix to correctly handle wrapped lines in shell command output. The change in shellExecutionService.ts correctly reconstructs long lines that were wrapped by the terminal. However, I've identified a potential regression in this new logic that could cause loss of significant trailing whitespace on the last line of a command's output. I've provided a suggestion to fix this while preserving the intended wrapping fix.

The current logic for determining trimRight may cause a regression. For the last line in the buffer, trimRight defaults to true, which will remove any intentional trailing whitespace. This could break tests that expect trailing whitespace to be preserved, such as the existing should not add extra padding but preserve explicit trailing whitespace test.

The logic should be adjusted to not trim the last line of the buffer if it's a standalone line (i.e., not part of a wrapped sequence). This preserves potentially significant trailing whitespace.

    let trimRight = true;
    if (i + 1 < buffer.length) {
      const nextLine = buffer.getLine(i + 1);
      if (nextLine?.isWrapped) {
        trimRight = false;
      }
    } else if (!line.isWrapped) {
      // Don't trim the last line of the buffer if it's a standalone line
      // to preserve potentially significant trailing whitespace.
      trimRight = false;
    }
