Detach from the Interpreter for Long-Running Rust Work (Highest Impact) + +In PyO3 0.28, `Python::allow_threads` has been renamed to **`Python::detach`**. This is the single most important optimization — it allows the Python interpreter to proceed without waiting for the current thread. + +On **GIL-enabled builds**, this is crucial as only one thread may be attached at a time. On **free-threaded builds** (Python 3.13t/3.14t), this is still essential because "stop the world" events (like garbage collection) force all attached threads to wait. + +**Rule of thumb:** Attaching/detaching takes <1ms, so any work expected to take multiple milliseconds benefits from detaching. + +```rust +use pyo3::prelude::*; +use pyo3::types::PyBytes; + +#[pyfunction] +fn parse_response<'py>(py: Python<'py>, data: &[u8]) -> PyResult> { + // ✅ Detach from interpreter during pure-Rust work + let parsed = py.detach(|| { + serde_json::from_slice::(data) + }).map_err(|e| pyo3::exceptions::PyValueError::new_err(e.to_string()))?; + + // Re-attach automatically; convert to Python only here + pythonize::pythonize(py, &parsed) +} +``` + +**Batch pattern — minimize attached time:** + +```rust +use rayon::prelude::*; + +#[pyfunction] +fn process_batch<'py>(py: Python<'py>, items: Vec) -> PyResult> { + // Phase 1: Detach and do heavy Rust work in parallel + let results = py.detach(|| { + items.into_par_iter() + .map(|item| item.to_uppercase()) // example transform + .collect::>() + }); + + // Phase 2: Return — PyO3 handles Vec → list[str] conversion + Ok(results) +} +``` + +--- + +## 2. Use `cast` Instead of `extract` for Type Checks + +This comes directly from the [PyO3 0.28 performance guide](https://pyo3.rs/v0.28.0/performance.html). When you're doing polymorphic dispatch and **ignoring the error**, use `cast` instead of `extract` to avoid the costly `PyDowncastError` → `PyErr` conversion. + +```rust +use pyo3::prelude::*; +use pyo3::types::{PyDict, PyList, PyString}; +use pyo3::exceptions::PyTypeError; + +#[pyfunction] +fn process<'py>(value: &Bound<'py, PyAny>) -> PyResult> { + // ✅ Use `cast` — avoids costly PyDowncastError → PyErr conversion + if let Ok(list) = value.cast::() { + process_list(list) + } else if let Ok(dict) = value.cast::() { + process_dict(dict) + } else if let Ok(s) = value.cast::() { + process_string(s) + } else { + // Only pay error conversion cost on the final fallback + Err(PyTypeError::new_err("Unsupported type")) + } +} +``` + +**When to use which:** + +| Method | Use When | Cost | +|--------|----------|------| +| `cast::()` | Type-checking native Python types, error is ignored | Cheap — no `PyErr` allocation | +| `extract::()` | You need the Rust value, or need the `PyErr` | More expensive due to error conversion | + +--- + +## 3. Zero-Cost Python Token Access via `Bound::py()` + +Another tip from the official performance page: if you already have a `Bound<'py, T>` reference, use `.py()` to get the `Python<'py>` token instead of calling `Python::attach`. `Python::attach` has a small but measurable cost from checking if the thread is already attached. + +```rust +use pyo3::prelude::*; +use pyo3::types::PyList; + +struct Inner(Py); + +struct InnerBound<'py>(Bound<'py, PyList>); + +impl PartialEq for InnerBound<'_> { + fn eq(&self, other: &Inner) -> bool { + // ✅ Zero-cost token access from existing Bound reference + let py = self.0.py(); + let other_len = other.0.bind(py).len(); + self.0.len() == other_len + } +} + +// ❌ Avoid: unnecessary Python::attach when you already have a Bound +// Python::attach(|py| { ... }) // has overhead from attachment check +``` + +--- + +## 4. Use Vectorcall Protocol for Calling Python + +PyO3 0.28 will use the more efficient `vectorcall` protocol (PEP 590) when you pass **Rust tuples** as call arguments. `Bound<'_, PyTuple>` and `Py` can only use the older, slower `tp_call` protocol. + +```rust +use pyo3::prelude::*; + +#[pyfunction] +fn call_callback(py: Python<'_>, callback: &Bound<'_, PyAny>) -> PyResult { + // ✅ Rust tuple → vectorcall (fast path) + let result = callback.call1((42, "hello", true))?; + + // ❌ Avoid: PyTuple → tp_call (slower path) + // let args = PyTuple::new(py, &[42.into_pyobject(py)?, ...])?; + // let result = callback.call1(args)?; + + Ok(result.unbind()) +} +``` + +**Key rule:** Prefer Rust tuples `(arg1, arg2, ...)` over constructing `PyTuple` for all `.call()`, `.call1()`, and `.call_method1()` invocations. + +--- + +## 5. Disable the Global Reference Pool + +PyO3 maintains a global mutable reference pool for deferred reference count updates when `Py` is dropped without being attached to the interpreter. The synchronization overhead can become significant at the Python-Rust boundary. + +Add to your `.cargo/config.toml`: + +```toml +[build] +rustflags = ["--cfg", "pyo3_disable_reference_pool"] +``` + +**Tradeoff:** With this flag, dropping a `Py` (or types containing it like `PyErr`, `PyBackedStr`, `PyBackedBytes`) without being attached will **abort**. So you must ensure all Python objects are dropped while attached: + +```rust +use pyo3::prelude::*; +use pyo3::types::PyList; + +// ✅ Correct: drop within an attached context +let numbers: Py = Python::attach(|py| PyList::empty(py).unbind()); + +Python::attach(|py| { + numbers.bind(py).append(42).unwrap(); +}); + +// Explicitly drop while attached +Python::attach(move |py| { + drop(numbers); // Safe — we're attached +}); +``` + +Optionally add `pyo3_leak_on_drop_without_reference_pool` to leak instead of abort (prevents crashes but may cause resource exhaustion long-term). + +--- + +## 6. Avoid Unnecessary Data Copies + +### Zero-copy buffer access + +```rust +use pyo3::prelude::*; + +#[pyfunction] +fn compute_checksum(data: &[u8]) -> u32 { + // `data` borrows directly from Python's buffer — zero copy + data.iter().fold(0u32, |acc, &b| acc.wrapping_add(b as u32)) +} +``` + +### Keep data Rust-side in `#[pyclass]` + +```rust +use pyo3::prelude::*; + +#[pyclass] +struct Response { + // Store as Rust types — no Python overhead + status: u16, + body: Option, // requires `bytes` feature in PyO3 0.28! + headers: std::collections::HashMap, +} + +#[pymethods] +impl Response { + #[getter] + fn status_code(&self) -> u16 { + self.status // Cheap: primitive copy + } + + fn json(&self, py: Python<'_>) -> PyResult { + let bytes = self.body.as_ref() + .ok_or_else(|| pyo3::exceptions::PyValueError::new_err("no body"))?; + // Convert to Python only on explicit request + py.detach(|| serde_json::from_slice::(bytes)) + .map_err(|e| pyo3::exceptions::PyValueError::new_err(e.to_string())) + .and_then(|v| Ok(pythonize::pythonize(py, &v)?)) + } +} +``` + +### New in 0.28: `bytes` crate integration + +PyO3 0.28 adds optional `bytes` crate support for zero-copy `bytes::Bytes` ↔ Python conversion: + +```toml +[dependencies] +pyo3 = { version = "0.28", features = ["bytes"] } +``` + +--- + +## 7. Smart Type Conversions with `IntoPyObject` + +PyO3 0.28 has fully removed the deprecated `ToPyObject` and `IntoPy` traits. Use **`IntoPyObject`** exclusively: + +```rust +use pyo3::prelude::*; +use std::collections::HashMap; + +#[pyfunction] +fn process_config(py: Python<'_>, data: &Bound<'_, PyAny>) -> PyResult { + // Extract once into Rust types, work in Rust + let map: HashMap = data.extract()?; + + let result = py.detach(|| { + map.into_iter() + .filter(|(k, _)| !k.starts_with("_")) + .collect::>() + }); + + // Single conversion back to Python using IntoPyObject + Ok(result.into_pyobject(py)?.into_any().unbind()) +} +``` + +**Use `Cow` to avoid allocation when possible:** + +```rust +use std::borrow::Cow; + +#[pyfunction] +fn normalize_url(url: &str) -> Cow<'_, str> { + if url.ends_with('/') { + Cow::Borrowed(url) // No allocation + } else { + Cow::Owned(format!("{}/", url)) + } +} +``` + +--- + +## 8. `#[pyclass]` Optimization + +```rust +use std::sync::Arc; + +#[pyclass(frozen)] // Immutable → no locking overhead on field access +#[pyclass(freelist = 256)] // Object pool for frequently created/destroyed objects +struct Headers { + inner: Arc, // Arc for cheap sharing across Rust threads +} +``` + +### Free-threaded Python support (0.28) + +PyO3 0.28 requires `#[pyclass]` types to implement `Sync` (for free-threaded builds). Free-threaded support is now **opt-out** rather than opt-in: + +```rust +// ✅ Works on both GIL-enabled and free-threaded builds +#[pyclass(frozen)] // Frozen makes Sync trivial for most types +struct Config { + timeout: u64, + base_url: String, +} + +// For mutable state, use interior mutability with Sync-safe primitives +use std::sync::Mutex; + +#[pyclass] +struct ConnectionPool { + connections: Mutex>, // Mutex is Sync +} +``` + +--- + +## 9.

You can verify this by checking the `X-Forwarded-For` or other headers if the backend instances were configured to log their unique IDs, but in this setup, it's handled transparently by Traefik. + +--- + +## 🛠 Troubleshooting + +### Port Conflicts +If you see an error like `Bind for 0.0.0.0:80 failed: port is already allocated`, ensure no other web servers (like Nginx or Apache) are running on your host. +- Check ports: `lsof -i :80` or `netstat -tuln | grep :80` + +### Docker Socket Permissions +Traefik needs access to `/var/run/docker.sock` to discover services. If you encounter permission issues, ensure your user is in the `docker` group or run with appropriate permissions. + +### SSL Verification Errors +When testing HTTPS, you might see `CERTIFICATE_VERIFY_FAILED`. +- **Curl**: Use the `-k` or `--insecure` flag. +- **Benchmark Tool**: Ensure the client adapter handles self-signed certificates (most adapters in this project support an `--insecure` or similar flag if implemented). + +--- + +## 📈 Integration with Benchmark Framework + +This server setup is optimized for use with the `http-client-benchmarker` CLI. + +### Example: Benchmarking against the Load Balancer +```bash +# Benchmark httpx against the HTTP endpoint +python -m http_benchmark.cli --url http://localhost/get --client httpx --concurrency 50 --duration 60 + +# Benchmark aiohttp against the HTTPS endpoint +python -m http_benchmark.cli --url https://localhost/get --client aiohttp --concurrency 50 --duration 60 --async +``` + +### Recommended Setup for Performance Testing +For high-concurrency benchmarks, always use the Traefik setup. It better reflects real-world scenarios where requests are proxied and distributed across multiple worker nodes, allowing you to test how client libraries handle connection pooling and keep-alive over a load balancer. diff --git a/httpbin_server/certs/server.crt b/httpbin_server/certs/server.crt new file mode 100644 index 0000000..0675ded --- /dev/null +++ b/httpbin_server/certs/server.crt @@ -0,0 +1,19 @@ +-----BEGIN CERTIFICATE----- +MIIDCTCCAfGgAwIBAgIUGiDR48weKWpA5zhm8uwSQqncd+YwDQYJKoZIhvcNAQEL +BQAwFDESMBAGA1UEAwwJbG9jYWxob3N0MB4XDTI2MDExMDAxMDgzNFoXDTI3MDEx +MDAxMDgzNFowFDESMBAGA1UEAwwJbG9jYWxob3N0MIIBIjANBgkqhkiG9w0BAQEF +AAOCAQ8AMIIBCgKCAQEAqNeLgOOoh3pvWB2yydsoyUrvbWrjD70ehrcHNS/ilNOC +GNFcLwkTgbJFwQ90l6GepShkXjDwSfXE7BTtsP7V9ripTpT3sMiBG5q4LE9hoVVW +/MoWq81WM4MCZgOxQpZF6V5P2kEm9F2s7UF1V/nZqAFJHu4BWD8R76lngB3NRY3k ++mlpPzxXkLk3Bq+b88n3eUcStyA1o5/9x6H2YCESbrA/xPktu812nRSSGvK+dKH8 +MrAP5PtUL7azjEEtWA9JN/uc3q5EKSe3NeowfWi6sX5hPXG+9nhNF4VTal4Ev3Nz +RAYuEvAu3HZh0xAvZcr6ZmWuDOaS0DdnR/Hte25tswIDAQABo1MwUTAdBgNVHQ4E +FgQUzpmnlnmTjd+e1QSFILEa3/K5fIQwHwYDVR0jBBgwFoAUzpmnlnmTjd+e1QSF +ILEa3/K5fIQwDwYDVR0TAQH/BAUwAwEB/zANBgkqhkiG9w0BAQsFAAOCAQEAYGM5 +SZvDw2Bj1ee5ZvqGMsprtv0zv/hMQak8BNvAs1tpgHpChqogn9NEXUVaSMs5Sa1W +TCMv2oc1Ort1JQVZjOSiDPf5o9p/zqcO/n1vTph8ZY+T9pdvGkGzQ33KZqbge3hO +Hy7H5FuRDWJz+xThx2g9RDr4xvN6tyCIp+xboX40dWJHorHaqkOPgSF/NfuQdyEE +Hi16wfhGpPunVjKk+ZkkIYyK6n5eJqS/SEAGbPAgT9FMuonqtjhapam/ZYyVuy8J +B9vwbUA0lHD1ET1VxxQx2k9rDLGv7tV27uTMop4Q4cW6wEaho+nzGPSCh2yYn6Qz +VpwXmVlxt7yOjKCbzA== +-----END CERTIFICATE----- diff --git a/httpbin_server/certs/server.key b/httpbin_server/certs/server.key new file mode 100644 index 0000000..a769892 --- /dev/null +++ b/httpbin_server/certs/server.key @@ -0,0 +1,28 @@ +-----BEGIN PRIVATE KEY----- +MIIEvgIBADANBgkqhkiG9w0BAQEFAASCBKgwggSkAgEAAoIBAQCo14uA46iHem9Y +HbLJ2yjJSu9tauMPvR6Gtwc1L+KU04IY0VwvCROBskXBD3SXoZ6lKGReMPBJ9cTs +FO2w/tX2uKlOlPewyIEbmrgsT2GhVVb8yharzVYzgwJmA7FClkXpXk/aQSb0Xazt +QXVX+dmoAUke7gFYPxHvqWeAHc1FjeT6aWk/PFeQuTcGr5vzyfd5RxK3IDWjn/3H +ofZgIRJusD/E+S27zXadFJIa8r50ofwysA/k+1QvtrOMQS1YD0k3+5zerkQpJ7c1 +6jB9aLqxfmE9cb72eE0XhVNqXgS/c3NEBi4S8C7cdmHTEC9lyvpmZa4M5pLQN2dH +8e17bm2zAgMBAAECggEACeRC3IS56WH/ZvKqeE/6JjzZJRhngBMM2Eidx/xrsltn +2ktdsrW96lHG62Yb5wxFbpictLX6ReL7q/cX69AqOd+cr6ljj3xXsAXS92mZJyoI +RBwU0vDfNXpd6BscRfHm26K2W+uIPDXGvUmh9csB+OlGXuUDuCdNxjQvB573WTU7 +5TJXdcXPNo63YNsPJlKtOnZc3xwG7xJrQDJWj0ReZZDEwYDIPRU8sWqdrs++s1Nz +WhpGhEtgZSrsJYeYsxkvPm9d95gyIxbQeX1wDkZ3Kq5jHIHvFGBYsrJC435Ik7wE +DZRsLX9w3e8uQjhp1US4yyaO2d4BPbc1+nJvfV3QFQKBgQDqbneW7Vz9bl7PkyTf +3iwJKbMFegUr3X+/eDr0jvVXuXA1ROGlnGdnhQmeBfvP3dObyhEVKM8dEjg29DXv +foLo8rDkaOFDpMxjW6CVWpKYO29J8fk/O0JzGJbATehNQu84tUp8o+fE/4h9QuRQ +5ixsbf2q127gLFr14S2VbmKaRQKBgQC4YEGno9TzoTUrknM7NXdKA3Zb4lV56k6g +v6T2+a5NVNwj0aIiN+dKbLu0AwAZW0nQa3I7eN7+GtbYCte4OCsbdChBg47x9nmP +gb+eSfk1r+33mQLYMFSeBLxDLwz/mDbEIsELFYNnvNrxtG5oVnGT8j+sgKdUg1wu +FQdbXVYjlwKBgQDErc8pUZTtjlZ+4d1S8GuTeGeYVanXBmrx8WXM3c9aPNq15kdF +kTVztTq/WBfOajXpgxrX3Lf+lNWSzUoe1s3vsATWbGNpQ+6yASJ1i1pn251ftWG+ +OfJi66M2TWZyw5A9zGNktIJzVUtmg+NXN/TXN2RVm46LBst9c+CxeL3C3QKBgCuL +YDYtdT/M1PfjcJ+NMw0h4DQ3MiTG96bzXAyQT2AoKI21Fuup9FAZegM7qixS6Q32 +MlZlZ5Tv1cnUVbpGWbf0KQXAAmSW54LDC/RgWCEb2cHeO1O/plxjlerwE8vRsS2F +X740aIJ5keP/zwuJTu24Ct28zMgi9gRUJxam5o8lAoGBAM12x2ZYNjp5XxVbHT67 +u2qSBmStXrAOZk3ojJKPP4gYa5S8APA+T1z0kiCV30NM2Ctcfhj77XBXJ2BXxpuj ++CPCufO3vXUZgAW7P8B3YReBwL71lF6Zst1LklxFuif0OCp4QyPpeXZOFV0Ka1uA +Upj2Em5jZYrjmGo9l0GPT8za +-----END PRIVATE KEY----- diff --git a/httpbin_server/docker-compose.httpbin-go.yml b/httpbin_server/docker-compose.httpbin-go.yml new file mode 100644 index 0000000..41c552b --- /dev/null +++ b/httpbin_server/docker-compose.httpbin-go.yml @@ -0,0 +1,24 @@ +services: + httpbin: + image: mccutchen/go-httpbin + container_name: httpbin-go + restart: unless-stopped + ports: + -
