Modified iterator implementation to remove count from equality comparison: - Changed increment operator to not wrap index (now stores unwrapped index) - Updated dereference operators to apply modulo when accessing elements - Modified end() to use tail_ + size_ instead of head_ for unique index - Removed count from operator== and operator!= comparisons This ensures two iterators are equal if they point to the same position in the same container, regardless of iteration count, following standard iterator semantics.

@copilot 你提交了太多没用的代码,google mock之类的 |
Removed _codeql_build_dir directory and _codeql_detected_source_root symlink that were accidentally committed. These are build artifacts from the CodeQL security scanner and should not be in version control. Updated .gitignore to prevent these files from being committed in the future.

1. RingBuffer.hpp:52
- Draft comment:
Using 'index_ % N' in operator* and operator-> correctly wraps the logical index. Consider extracting this modulo computation into a helper function to reduce duplication. - Reason this comment was not posted:
Decided after close inspection that this draft comment was likely wrong and/or not actionable: usefulness confidence = 30% vs. threshold = 50% This is a code quality refactoring suggestion. The rules state that "Comments that suggest code quality refactors are good! But only if they are actionable and clear." This comment is both actionable (extract to helper function) and clear (reduce duplication ofindex_ % N). However, I need to consider: 1) Is this duplication significant enough to warrant a comment? It appears 4 times in a small section. 2) Is this obvious or unimportant? The duplication is relatively minor - just 4 occurrences of a simple expression. 3) Would a helper function actually improve readability here, or would it add unnecessary indirection for such a simple operation? The expressionindex_ % Nis quite readable as-is. While the suggestion is technically valid and actionable, extracting such a simple expression (index_ % N) into a helper function might be overkill and could reduce readability rather than improve it. The duplication is minimal (4 occurrences) and the expression is straightforward. This might fall under "obvious or unimportant" suggestions that shouldn't be made. The comment is actionable and clear, which meets the criteria for code quality refactors. However, given that it's a very simple expression with only 4 occurrences in closely related functions, and that extracting it might not meaningfully improve the code, this suggestion is likely too minor to be valuable. It's the kind of refactoring that could go either way, and the rules emphasize not making obvious or unimportant comments. This is a borderline case, but the refactoring suggestion is too minor for such a simple expression. The duplication ofindex_ % Nfour times is not significant enough to warrant extraction to a helper function, and doing so might reduce clarity. This falls under "obvious or unimportant" suggestions.
2. RingBuffer.hpp:67
- Draft comment:
Operator++ now simply increments index_ (without modulo), relying on operator* for modulo wrapping. Confirm this logical index approach is intended and documented. - Reason this comment was not posted:
Comment looked like it was already resolved.
3. RingBuffer.hpp:95
- Draft comment:
Iterator equality now compares only the source and index, excluding count. Ensure that omitting count doesn’t lead to false equality, even if two iterators reached the same index via different paths. - Reason this comment was not posted:
Comment looked like it was already resolved.
4. RingBuffer.hpp:101
- Draft comment:
Inequality operator was updated to mirror equality (ignoring count). Verify that comparing only source and index is sufficient for all iterator uses. - Reason this comment was not posted:
Comment did not seem useful. Confidence is useful =0%<= threshold50%The comment is asking the author to verify if comparing only source and index is sufficient for all iterator uses. This falls under asking the author to double-check or ensure behavior, which is against the rules.
5. RingBuffer.hpp:217
- Draft comment:
The end iterator is now constructed using 'tail_ + size_' instead of 'head_'. This change more accurately represents the logical end in a wrapped ring buffer. Please ensure corresponding tests cover wrap-around cases. - Reason this comment was not posted:
Comment did not seem useful. Confidence is useful =0%<= threshold50%The comment is asking the author to ensure that tests cover specific cases related to a change in the code. This is a request for confirmation rather than a specific suggestion or identification of a missing test. It violates the rule against asking the author to ensure that their change is tested.

Pull request overview
This PR refactors the ring buffer iterator implementation to fix semantic issues with iterator equality comparison and simplify the iteration logic.
Changes:
- Modified iterator to use unbounded index growth with modulo applied only at dereference time
- Fixed iterator equality comparison to only compare source and index, removing count from the comparison
- Updated end() iterator construction to use tail_ + size_ instead of head_
- Added CodeQL build artifact to .gitignore
