PR fix notes

PR #25713: fix(TableRenderer): guard against negative column widths in renderBorder

Description (problem / solution / changelog)

Problem

When the terminal is very narrow, adjustedWidths can contain values that, after the column allocation algorithm scales them down, result in a width of 0 or negative. Calling String.prototype.repeat() with a negative count throws:

RangeError: Invalid count value: -1

This crash was reported in issue #25665.

Root cause

In renderBorder, the border segments are built with:

const borderParts = adjustedWidths.map((w) => char.horizontal.repeat(w));

repeat() requires a non-negative integer. When the terminal is too narrow for the table, adjustedWidths can contain negative values, crashing the renderer.

Fix

Clamp each width to a minimum of 0 before passing it to repeat():

const borderParts = adjustedWidths.map((w) => char.horizontal.repeat(Math.max(0, w)));

This matches the existing defensive pattern already used in renderCell:

const contentWidth = Math.max(0, width - COLUMN_PADDING);

Fixes #25665

extent analysis

TL;DR

The issue is likely caused by an unhandled promise rejection due to an invalid count value in the String.repeat function, and a workaround may involve updating the gemini-cli version or modifying the code to handle this edge case.

Guidance

  • The error message indicates a RangeError: Invalid count value: -1 at the String.repeat function, which suggests that the code is attempting to repeat a string with a negative count.
  • To verify the issue, check the code at chunk-AQRXALHQ.js:37307:89 to see where the String.repeat function is being called with a negative count.
  • To mitigate the issue, consider updating the gemini-cli version to a newer release, if available, or modifying the code to handle the case where the count is negative.
  • Additionally, check the terminal background color and other environmental factors to ensure they are not contributing to the issue.

Example

No code example is provided as the issue is related to a specific version of the gemini-cli and the code is not readily available.

Notes

The issue may be specific to the gemini-cli version 0.38.2 and the darwin operating system. Further investigation is needed to determine the root cause and a permanent fix.

Recommendation

Apply a workaround by modifying the code to handle the case where the count is negative, as updating to a fixed version may not be available.
