Summary of Changes
Hello @haochengxia, 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!
I've implemented a significant code hygiene improvement by introducing and applying automated formatting tools for both C++ and Python files. My goal was to establish a consistent code style across the repository, making the codebase more readable and maintainable. This involved adding configuration files for clang-format and ruff, and then applying these formatters to existing code, resulting in changes to whitespace, line breaks, and argument alignments in several files. I also updated the .gitignore to reflect new project dependencies.
Highlights
- New C++ Formatting Configuration: I introduced a new
.clang-formatconfiguration file to enforce consistent C++ code styling across the project. This file is based on the Google style guide and sets a column limit of 80 characters. - Git Ignore Update: I updated the
.gitignorefile to includeuv.lock, ensuring that this dependency lock file is not tracked by version control. - Python Code Formatting: I applied automatic formatting to several Python files, specifically
libcachesim/synthetic_reader.pyandlibcachesim/trace_reader.py, to align them with the project's new formatting standards. This included reformatting a multi-line import statement for better readability. - C++ Code Formatting: I applied automatic formatting to C++ source files, including
src/export_cache.cppandsrc/export_reader.cpp. These changes primarily involved adjusting pointer cast syntax, aligning function arguments, and reformatting multi-line statements for improved code clarity and consistency.

Code Review
This pull request focuses on applying automated code formatting to C++ and Python files using clang-format and ruff. It also introduces the .clang-format configuration and updates .gitignore. While the formatting changes are well-applied and improve code consistency, I've identified a critical issue in one of the touched C++ files. A missing null check after a calloc memory allocation could lead to a null pointer dereference and a program crash. My review includes a suggestion to fix this vulnerability.
