Fix calculation when divided by zero. If anywhere, any value is divid… #23

…ed by zero, there can be a fatal.
WalkthroughThe changes involve modifications to various methods across multiple files to enhance error handling and prevent division by zero errors in calculations related to shipping amounts, commission rates, and migration progress. Key adjustments include ensuring that divisor values default to 1 when associated arrays or totals are empty or invalid. These updates improve the robustness of financial calculations and shipping distributions within the order processing and migration logic. Changes

122-124: Good catch on preventing division by zero, but consider more accurate fallback values.Defaulting the subtotal to 1 when it's empty or less than 1 effectively prevents division by zero errors in the commission rate calculations. This is a positive change that improves the robustness of the code.
However, always defaulting to 1 might not be the most accurate approach in all scenarios. It could potentially lead to incorrect commission calculations in edge cases where the subtotal is legitimately zero or negative.
Consider alternative fallback values or error handling mechanisms based on your specific business requirements. For example:
- Use a small positive epsilon value close to zero instead of 1.
- Throw an exception or log an error message to alert about the unexpected subtotal value.
- Define a default commission rate to use when the subtotal is invalid.
Discuss with the team and stakeholders to determine the most appropriate approach that aligns with your business logic and handles these edge cases accurately.

222-222: Fallback for undefined package quantity.The change sets the package quantity to 1 if it is not already defined when processing refunds. This provides a fallback value to prevent issues with undefined
$package_qtyin subsequent shipping calculations.While setting the package quantity to 1 allows the refund process to proceed without errors, it may not accurately represent the original package quantity. Consider using the actual package quantity if it is available from other sources or order data.
415-421: Safeguard against empty vendor count.The changes introduce a safeguard to handle cases where the count of vendors is empty. By defaulting
$vendors_countto 1 whencount($vendors)is empty, the shipping and tax amounts are still split, preventing division by zero errors.However, when there are no vendors associated with the order, splitting the shipping costs equally among a default count of 1 may not be the most accurate approach. Consider handling the case of no vendors differently, perhaps by assigning the full shipping costs to the parent order or using a different distribution logic.

206-206: Good catch! This change prevents division by zero errors.Defaulting
$vendors_countto 1 when$vendorsarray is empty is a crucial safeguard. It ensures that subsequent division operations always have a valid divisor, preventing potential crashes or unexpected behavior.
210-210: Looks good! The shipping costs are now split correctly.Dividing the total shipping tax and shipping amount by
$vendors_countensures that each vendor suborder gets an equal share of the shipping costs. This maintains fairness in cost distribution among vendors.The previous safeguard of defaulting
$vendors_countto 1 when$vendorsis empty guarantees that these divisions are always valid, preventing any potential issues.Also applies to: 212-212

207-209: LGTM! The change effectively prevents division by zero errors.The introduction of the
total_countvariable, which defaults to 1 when$this->total_countis empty, ensures that the progress calculation will not encounter division by zero errors. This change enhances the robustness of the migration process by handling scenarios where the total count may be invalid.The logic flow remains intact, and the modification improves error handling in the progress calculation.

120-122: LGTM!The changes introduce a safeguard to prevent division by zero errors when calculating the vendor's commission rate. By defaulting the divisor to 1 when
$order->item_sub_totalis empty or less than 1, the calculation remains robust even in edge cases.The updated logic ensures the commission rate is calculated correctly without introducing any apparent issues or side effects.
