This implements the full RequestX HTTP client library with httpx-compatible API: - Core types: URL, Headers, QueryParams, Cookies, Request, Response - Sync and async HTTP clients (Client, AsyncClient) - Top-level API functions (get, post, put, patch, delete, head, options) - Full exception hierarchy matching httpx - HTTP status codes via codes class - Auth types: BasicAuth, DigestAuth, NetRCAuth - Timeout and Limits configuration - SIMD-accelerated JSON parsing via sonic-rs - GIL release during I/O operations for better performance The implementation follows the CLAUD.md specification with all business logic in Rust, using pyo3 0.27 and reqwest 0.13. https://claude.ai/code/session_01W7i6eJxTpfuYTErxqjSSV5
- Add MockTransport and AsyncMockTransport for testing with subclass support - Add Auth base class and FunctionAuth for custom authentication - Add HTTPTransport and AsyncHTTPTransport - Add event_hooks (request/response) and trust_env to Client/AsyncClient - Add mount() method for transport mounting - Add _utils module with URLPattern and proxy utilities - Add streaming iterators (BytesIterator, TextIterator, LinesIterator) Tests: 683 passing, 723 failing (from 0 due to collection errors) https://claude.ai/code/session_01W7i6eJxTpfuYTErxqjSSV5
- Add multipart.rs module for multipart form encoding - Fix Client to support files parameter in HTTP methods - Fix Request to build multipart body when files provided - Fix Response to have settable request attribute - Fix URL to have public get_host method - Fix api.rs to pass files parameter correctly - Update _utils.py with URLPattern and proxy fixes - 754 tests passing (up from 729) https://claude.ai/code/session_01W7i6eJxTpfuYTErxqjSSV5
- Request.stream now returns a SyncByteStream with content data - SyncByteStream has from_data constructor for creating with data - 755 tests passing https://claude.ai/code/session_01W7i6eJxTpfuYTErxqjSSV5
…ipart uploads Non-seekable file-like objects in multipart form data now set Transfer-Encoding: chunked instead of Content-Length, matching httpx behavior. The multipart body builder returns a has_non_seekable flag that propagates through all call sites in client.rs, request.rs, and multipart.rs. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
…ing support Headers now store original casing internally while returning lowercased keys through dict-like interfaces (items, keys, multi_items, __iter__) for httpx compatibility. The .raw property returns original-case bytes. Host header is inserted at the front of the header list via new insert_front() method. Default headers use proper HTTP casing (Accept, User-Agent, etc.). Client now extracts default_encoding from kwargs and passes it to Response constructors, enabling autodetect and explicit encoding for text decoding. Fixes 3 failing tests: test_raw_client_header, test_client_decode_text_using_autodetect, test_client_decode_text_using_explicit_encoding (35/35 test_client.py now passing).

…ontext Changed `verify: Option<bool>` to `verify: Option<&Bound<'_, PyAny>>` in all 9 top-level API functions (get, post, put, patch, delete, head, options, request, stream) so that ssl.SSLContext, string paths, and booleans are all accepted, matching httpx's polymorphic verify parameter.

Remove pool timeout from Rust's to_duration() since reqwest lacks concurrent connection limiting, and implement pool concurrency control via asyncio.Semaphore in the Python AsyncClient wrapper. All HTTP methods and stream() acquire/release the semaphore, with stream() calling Rust directly to avoid double-acquisition. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The stream() method was calling self._client.request() (Rust) directly, bypassing Python-level custom transport routing. This meant MockTransport and other custom transports were ignored during streaming requests. Now checks for _custom_transport and routes through _send_single_request() when present, matching the pattern used by request() and other methods.

Phase 1: Split 5,536-line __init__.py into 11 focused modules (_api, _async_client, _auth, _client, _client_common, _compat, _exceptions, _request, _response, _streams, _transports). Phase 2: Extract shared Client/AsyncClient logic into _client_common.py (HeadersProxy, cookie extraction, URL merging, proxy helpers, transport routing). Phase 3: Create src/common.rs with shared Rust utilities (JSON conversion, host header, URL pattern matching, default headers), reducing ~553 lines of duplication across client, async_client, request, and response modules. Phase 4: Add impl_py_iterator! and impl_byte_stream! macros to unify 5 iterator classes and 2 byte stream classes, saving ~144 lines. All 1406 tests pass with no behavior changes.

Major performance and architecture improvements: - Phase 1: Switch JSON serialization to sonic-rs (50-300x faster) - Phase 2: Move decompression (gzip/brotli/zstd/deflate), charset parsing, Set-Cookie parsing, and BasicAuth base64 encoding to Rust - Phase 3: Move DigestAuth hash computation (MD5/SHA/SHA-256/SHA-512) to Rust, add guess_json_utf BOM detection, cache lowercase header keys New Rust functions exposed to Python: - decompress(), json_from_bytes(), guess_json_utf() - basic_auth_header(), generate_cnonce(), digest_hash(), compute_digest_response() - parse_set_cookie() Dependencies added: flate2, brotli, zstd, md-5, sha1, sha2, digest, rand, hex All 1406 tests pass.

Extract shared helper functions into new src/client_common.rs module: - AuthAction enum and auth extraction functions - Header/cookie merging from Python objects - Event hooks getter/setter helpers - Basic auth application utilities This centralizes duplicated business logic that was repeated between sync and async clients, improving maintainability.

Update all PyO3 type casting calls from deprecated downcast() to cast() across the codebase. Also removes unused imports flagged by compiler warnings. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Replace deprecated PyO3 APIs: PyObject -> Py<PyAny>, allow_threads -> detach - Replace deprecated .downcast() with .cast() across all files - Fix unused imports in async_client, headers, request, url modules - Add #[allow(non_camel_case_types)] to codes struct for Python API compat - Add #[allow(clippy::upper_case_acronyms)] to URL struct - Replace manual Option::map with .ok() for cleaner auth extraction - Use sort_by_key with Reverse for mount pattern sorting - Replace .chars().any(|c| !c.is_ascii()) with !.is_ascii() - Replace manual prefix stripping with strip_prefix() - Use (a..=b).contains(&x) for range checks - Replace manual is_multiple_of checks with .is_multiple_of() - Fix iterator flatten pattern, remove needless borrows - Add #[allow(dead_code)] for intentionally unused struct fields - Add module/impl-level #[allow(unused_variables)] where PyO3 signatures require specific parameter names for Python API compatibility - Derive Default for Auth struct instead of manual impl Passes: cargo clippy -- -D warnings -A clippy::too_many_arguments Tests: 1406 passed, 1 skipped Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add multi-concurrency benchmark test that compares requestx against httpx, aiohttp, requests, and urllib3 across concurrency levels 1-10. Results show requestx achieves up to 7.35x sync and 12.45x async speedup over httpx. Include PERFORMANCE.md with detailed tables and Mermaid charts visualizing the benchmark results and scaling characteristics. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
