1309-1338: Improve error handling and messages inparseParamSquareBrackets.The function correctly implements the logic to handle unmatched brackets by using a counter. However, the error messages could be more descriptive. Consider including more context or the problematic part of the input in the error message to aid in debugging.
Additionally, ensure that all edge cases, such as strings ending with an unmatched bracket or strings with nested brackets, are handled correctly.
Consider enhancing the error messages with the following changes:
- return "", errors.New("unmatched brackets") + return "", fmt.Errorf("unmatched brackets in input: %s", k)This change provides more context in the error message, making it easier to identify where the problem occurs in the input.

4511-4513: Check for unmatched brackets in query parameters.The test case at lines 4511-4513 correctly checks for unmatched brackets in the query string, which is a good practice to ensure the robustness of the query parsing logic. This helps in preventing potential errors during runtime due to malformed query parameters.

Duplicate test for unmatched brackets in query parameters.
The test cases at lines 4511-4513 and 4797-4799 are duplicates, testing the same functionality of checking for unmatched brackets in query parameters. Consider consolidating these tests or ensuring they cover different scenarios to avoid redundancy in the test suite.

we should have the same logic in the main branch for version 3, can you also make a pull request there |

Sure @ReneWerner87, will create a PR for v3. |

1309-1338: Review the logic for handling unmatched brackets inparseParamSquareBrackets.The function
parseParamSquareBracketshas been updated to handle unmatched brackets more robustly by introducing a counter for open brackets. Here are a few observations and suggestions:
Bracket Counting Logic: The use of
openBracketsCountto track the number of unmatched open brackets is a good approach. It increments the count when an open bracket[is found and decrements it when a close bracket]is found. This helps in identifying unmatched brackets effectively.Error Handling: The function returns an error if
openBracketsCountis negative (more closing than opening brackets) or if it's positive after processing all characters (more opening than closing brackets). This is crucial for preventing the processing of malformed queries that could lead to errors downstream.Improvement Suggestion: While the current implementation covers the basic cases of unmatched brackets, it might be beneficial to include more detailed error messages that could help in debugging. For example, indicating the position of the unmatched bracket could enhance the error's usefulness.
Performance Consideration: The function iterates over each character in the input string, which is efficient given the need to check each character for brackets. However, if performance becomes a concern, especially with very long strings, consider benchmarks to evaluate if optimizations are necessary.
Overall, the changes enhance the robustness of query parameter parsing by preventing errors related to unmatched brackets. It's a valuable update given the potential impact of such errors on application stability.

Description
Add logic to keep count of open brackets. If there's a mismatch between the number of open and close brackets, then return error.
