Conversation
Fixes googleapis#15234. Thanks to @strophy for the original analysis.
Summary of ChangesHello @devbww, 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 resolves an issue in the Spanner client library's ISO8601 interval parsing mechanism. It refactors the parsing logic to correctly handle the initial prefixes and the transition from date to time components, specifically by introducing a flag to manage the 'T' separator. This change prevents a subtle bug related to comparing iterators from different containers, enhancing the robustness and correctness of interval string interpretation. Highlights

Code Review
This pull request effectively addresses a potential undefined behavior bug in the ISO 8601 interval parser. By replacing the comparison of iterators from different containers with a boolean flag, the code is now safer and more correct. Additionally, the change improves error handling for missing 'P' designators, making the parser more robust. The changes are clear and well-implemented. I've added one minor suggestion to improve code readability.
