Potential fix for https://github.com/apache/tsfile/security/code-scanning/17
To fix the issue, we need to ensure that the multiplication is performed using a larger integer type (e.g.,
int64_t) to prevent overflow. This can be achieved by explicitly casting one of the operands toint64_tbefore the multiplication. This ensures that the multiplication is performed in 64-bit arithmetic, avoiding overflow.The specific change will be made on line 191, where the multiplication
points_per_device * device_numoccurs. We will castpoints_per_devicetoint64_tbefore the multiplication. This change does not alter the logic or functionality of the code but ensures that the multiplication is safe.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
