Benchmarks showed ~20% speedup for validation loops and ~2x for simple sanitization hoisting. **Action:** Identify calculations inside loops that don't depend on the loop variable and move them out. Use local variables for frequently accessed global/object methods. + ## 2026-02-04 - [Optimize Buffer for Large Downloads] **Learning:** When downloading large files (e.g., blocklists), the default chunk size of HTTP libraries might be small, leading to excessive loop iterations and list operations. Increasing the buffer size (e.g., to 16KB) reduces CPU overhead during I/O-bound operations. **Action:** When using `iter_bytes()` or similar streaming methods for large resources, explicitly set a larger `chunk_size` (e.g., 16384) to improve throughput and reduce CPU usage. + +## 2024-03-24 - [Avoid Regex on Simple Strings] +**Learning:** Running complex regex substitutions on every log message (for sanitization) introduces measurable CPU overhead, especially when most strings don't contain sensitive patterns. Simple string checks (`in`) are orders of magnitude faster than regex execution. +**Action:** Add early return checks (e.g., `if "://" in s:`) before invoking expensive regex operations in hot paths like logging or string sanitization. ## 2024-03-24 - Thread Pool Churn **Learning:** Python's `ThreadPoolExecutor` incurs measurable overhead (thread creation/shutdown) when created/destroyed repeatedly inside loops, even with small worker counts. **Action:** Lift `ThreadPoolExecutor` creation to the highest possible scope and pass it down as a dependency (using `contextlib.nullcontext` for flexible ownership). diff --git a/README.md b/README.md index 48e5ab8..f620b8e 100644 --- a/README.md +++ b/README.md @@ -35,10 +35,9 @@ https://controld.com/dashboard/profiles/741861frakbm/filters ### Configure the script -1. **Fork & clone** - > Fork this repo first (click **Fork** on GitHub), then clone your fork: +1. **Clone & install** ```bash - git clone https://github.com/YOUR_USERNAME/ctrld-sync.git + git clone https://github.com/your-username/ctrld-sync.git cd ctrld-sync ``` @@ -129,20 +128,23 @@ This project includes a comprehensive test suite to ensure code quality and corr **Basic test execution:** ```bash -# Dev dependencies are included when you run `uv sync` (see Quick start) -uv run pytest tests/ +# Install dev dependencies first +pip install pytest pytest-mock pytest-xdist + +# Run all tests +pytest tests/ ``` **Parallel test execution (recommended):** ```bash # Run tests in parallel using all available CPU cores -uv run pytest tests/ -n auto +pytest tests/ -n auto # Run with specific number of workers -uv run pytest tests/ -n 4 +pytest tests/ -n 4 ``` -**Note on parallel execution:** The test suite is currently small (~95 tests, <1s execution time), so parallel execution overhead may result in longer wall-clock time compared to sequential execution.
