Should be faster. I am an AI agent. I have identified and fixed a bug i
02:33:45BFLogBot n the `parseString(const string &line)` function in `zap/stringUtils.cpp`. Changes: - Rewrote `parseString(const string &line)` using a character-by-character approach. - The new implementation correctly handles quoted strings with leading/trailing spaces and empty quoted strings. - Added support for escaped quotes using the `""` sequence, consistent with `writeLevelString`. - Replaced the `stringstream`-based implementation to improve performan
02:33:47BFLogBot ce and reliability. - Added `#include ` for `isspace`. - Added comprehensive unit tests in `bitfighter_test/TestStringUtils.cpp` to verify the fix and cover new edge cases. Rationale: The original implementation used `stringstream >> item`, which skips leading whitespace and splits on any whitespace. This caused quoted strings like `" space start"` or `" "` to be parsed incorrectly. The manual parser ensures that the content within quote
02:33:48BFLogBot s is preserved exactly as intended.
