From bebb1dd1dd56242bd24c4c0cfd816a61c666c917 Mon Sep 17 00:00:00 2001 From: Artur Shiriev Date: Sun, 31 May 2026 21:18:44 +0300 Subject: [PATCH 01/13] docs(story-1.7): design for AsyncClient MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The v0.1.0 entry point of httpware: a single AsyncClient class wiring together the substrate from Stories 1-2 through 1-6 plus the middleware infrastructure from 2-1/2-2/2-3. Pragmatic scope: middleware wired via compose(); auth=, data=, files=, transport ref-counting, and streaming all deferred. Decisions: - src/httpware/client.py is the new module. - Keyword-only __init__ with sensible defaults (Httpx2Transport, PydanticDecoder, empty middleware). - 8 HTTP methods (get/post/put/patch/delete/head/options/request) with @overload-based response_model typing — ty validates. - httpx-style prefix join for base_url; per-call params override defaults. - ClientConfig extended with decoder + middleware fields (backwards- compatible). - Lifecycle: original owns transport, views from with_options are no-op on close (simpler than archive Decision 9; ref-counting deferred). - with_options accepts a keyword allowlist; limits/transport excluded. ~38 tests across six new test files. CHANGELOG bullet documents the public surface plus the explicit out-of-scope items.

Ships the main public surface: `AsyncClient` with HTTP method shortcuts, typed `response_model` overloads, per-call overrides, lifecycle management, and `with_options`. Wires middleware via `compose()` (Story 2-1) since that story already landed. Out of scope: `auth=` parameter (Story 2-4), `data=`/`files=` body params (follow-up), transport reference-counting (deferred), streaming (Epic 4), observability (Epic 5), `RecordedTransport` (Story 1-8). +- **Roadmap pointer:** `docs/engineering.md` §8 "Epic 1 — Make typed HTTP requests with sensible defaults". + +## Why + +`AsyncClient` is the v0.1.0 entry point of httpware. Stories 1-2 through 1-6 built the substrate (data types, exceptions, transport, decoders); stories 2-1 through 2-3 built the middleware infrastructure. Story 1-7 stitches them into a single ergonomic class: construct it, issue HTTP requests with optional typed responses, close it. + +The pragmatic scope decision: wire middleware now since `compose()` exists, but defer `auth=` to Story 2-4 (which has its own coercion-rule design surface), defer the more complex body params (`data`/`files`), and skip transport reference-counting in favor of a simpler "original owns lifecycle" model. This keeps Story 1-7 tractable while shipping a useful client. + +## Decisions + +| Decision | Choice | +| --- | --- | +| Scope | Pragmatic — middleware wired, no `auth=`, no transport ref-counting, body params limited to `json` and `content`. | +| Module location | `src/httpware/client.py` (top-level module). | +| Construction | Keyword-only `__init__`; sensible defaults (`Httpx2Transport`, `PydanticDecoder`, empty middleware). | +| `from_url` | Thin classmethod factory: `return cls(base_url=base_url, **kwargs)`. | +| `timeout` polymorphism | `Timeout \| float \| None` — bare `float` coerces to `Timeout(connect=x, read=x, write=x, pool=x)`; `None` → default `Timeout()`. | +| `middleware` type | `Sequence[Middleware]` (matches `compose`'s signature; accepts tuples). | +| `ClientConfig` extension | Add `decoder: ResponseDecoder` and `middleware: tuple[Middleware, ...]` fields with defaults. Backwards-compatible. | +| URL join | httpx-style prefix join: `base_url` is treated as a literal prefix with slash normalization; absolute URLs pass through. | +| Body params | `json` (stdlib `json.dumps(...).encode()`, auto-sets `Content-Type: application/json`) and `content` (raw bytes). Passing both raises `TypeError`. | +| Default merging | Per-call `headers`/`params` override per-client defaults via `{**default, **per_call}`. No client-level cookie jar; per-call only. | +| Response decoding | `response_model is None` → returns `Response`. `response_model: type[T]` → returns `self._config.decoder.decode(response.content, response_model)`. | +| Typed overloads | Two `@overload` declarations per HTTP method (None-response_model vs typed-response_model). 8 methods × 2 overloads = 16 stubs. `ty` validates via `tests/test_client_typing.py`. | +| HTTP methods | `get`, `post`, `put`, `patch`, `delete`, `head`, `options`, `request` (8 total). `request` adds a leading `method` positional parameter. | +| Lifecycle | `__aenter__` returns `self`. `__aexit__` calls `transport.aclose()` only if `_owns_transport=True`. | +| `with_options` | Keyword-only allowlist (`base_url`, `default_headers`, `default_query`, `timeout`, `decoder`, `middleware`). Returns a new `AsyncClient` with `_owns_transport=False` sharing the same transport. `limits` and `transport` are not allowed (would require swapping transports). | +| Transport lifecycle model | Simple: the original `AsyncClient` owns the transport. Views from `with_options` do not. No ref-counting. View `__aexit__` is a no-op. | +| Integration tests against external hosts | Not included. Archived AC mentions `httpbingo.org`; deferred to an opt-in `@pytest.mark.integration` test for a follow-up. | + +## File structure + +**New files:** +- `src/httpware/client.py` — `AsyncClient` class and supporting internals. +- `tests/test_client_construction.py` — defaults, `from_url`, param validation. +- `tests/test_client_methods.py` — 8 HTTP methods build correct Requests; default merging; URL resolution. +- `tests/test_client_response_model.py` — decoder invocation; `response_model is None` returns raw `Response`. +- `tests/test_client_typing.py` — `ty`-checked file verifying overload return types. +- `tests/test_client_lifecycle.py` — `async with`, view no-op on close, double-close safety. +- `tests/test_client_middleware_wiring.py` — middleware actually runs; `with_options(middleware=...)` re-composes. + +**Modified files:** +- `src/httpware/config.py` — extend `ClientConfig` with `decoder` and `middleware` fields. +- `src/httpware/__init__.py` — export `AsyncClient` at package root. +- `CHANGELOG.md` — Story 1.7 bullet. + +**Files NOT touched:** +- `src/httpware/request.py`, `response.py`, `errors.py`, `decoders/*`, `middleware/*`, `_internal/*`, `transports/*`. +- `pyproject.toml`. + +## Construction + +```python +class AsyncClient: + """Async HTTP client with typed response decoding and middleware composition.""" + + _config: ClientConfig + _transport: Transport + _dispatch: Next + _owns_transport: bool + + def __init__( + self, + *, + base_url: str | None = None, + default_headers: Mapping[str, str] | None = None, + default_query: Mapping[str, str] | None = None, + timeout: Timeout | float | None = None, + limits: Limits | None = None, + transport: Transport | None = None, + decoder: ResponseDecoder | None = None, + middleware: Sequence[Middleware] | None = None, + ) -> None: + normalized_timeout = _normalize_timeout(timeout) + resolved_limits = limits or Limits() + resolved_transport = transport or Httpx2Transport( + limits=resolved_limits, timeout=normalized_timeout + ) + resolved_decoder = decoder or PydanticDecoder() + resolved_middleware = tuple(middleware) if middleware is not None else () + + self._config = ClientConfig( + base_url=base_url, + default_headers=dict(default_headers or {}), + default_query=dict(default_query or {}), + timeout=normalized_timeout, + limits=resolved_limits, + decoder=resolved_decoder, + middleware=resolved_middleware, + ) + self._transport = resolved_transport + self._dispatch = compose(resolved_middleware, resolved_transport) + self._owns_transport = True + + @classmethod + def from_url(cls, base_url: str, **kwargs: Any) -> "AsyncClient": + """Construct an AsyncClient with a base URL prefix.""" + return cls(base_url=base_url, **kwargs) +``` + +`_normalize_timeout`: + +```python +def _normalize_timeout(value: Timeout | float | None) -> Timeout: + if value is None: + return Timeout() + if isinstance(value, Timeout): + return value + return Timeout(connect=value, read=value, write=value, pool=value) +``` + +`ClientConfig` is extended: + +```python +@dataclass(frozen=True, slots=True) +class ClientConfig: + base_url: str | None = None + default_headers: Mapping[str, str] = field(default_factory=dict) + default_query: Mapping[str, str] = field(default_factory=dict) + timeout: Timeout = field(default_factory=Timeout) + limits: Limits = field(default_factory=Limits) + decoder: ResponseDecoder = field(default_factory=PydanticDecoder) + middleware: tuple[Middleware, ...] = () +``` + +Existing tests for `ClientConfig` (Story 1-2) keep passing because the new fields have defaults.

Worked-example pattern in Section "HTTP methods and overloads" is taken from typeshed and httpx's own stubs. | +| The `_UNSET` sentinel leaks into reprs or error messages. | `_UNSET` is a private module-level constant; never appears in user-facing output. The `with_options` method body resolves it before storing anything in `ClientConfig`. | +| `ClientConfig` carrying `decoder` and `middleware` couples the config dataclass to those concepts (was previously pure transport config). | Accepted. The alternative (separate config types per concern) adds friction without value at this scale. | +| `_resolve_url` slash-normalization is wrong for some edge case (multiple slashes mid-URL, trailing slash on path). | The rule (`f"{base.rstrip('/')}/{path.lstrip('/')}"`) covers the common cases. Edge cases (e.g., `path="//foo"`) are user errors and are not normalized further. Documented in the docstring. | +| Views are confusing — users expect `async with view:` to clean up. | Docstrings on both `AsyncClient.__aexit__` and `with_options` explain the model clearly. The simpler-than-Decision-9 lifecycle is a documented tradeoff; ref-counting can be added later without breaking the public API. | +| The `_from_view` constructor uses `cls.__new__(cls)` and bypasses `__init__`, which can surprise subclasses. | `AsyncClient` is not designed for subclassing in v0. Subclasses that override `__init__` will break. Acceptable for v0; documented. | +| `tests/test_client_typing.py` runs `ty check` as part of `just lint-ci`, but isn't a runtime pytest test. | Add a one-line runtime test inside the file (`def test_typing_module_imports_cleanly`) that simply imports the typed names. Coverage will show the file is reachable; `ty` does the real work. | +| Decoder error during `decode()` masks a successful response. | `decode` raises `pydantic.ValidationError` / `msgspec.ValidationError` per Stories 1-5 and 1-6. AsyncClient does not catch — caller sees the validation error with the original content available on the (already-returned-but-not-yet-decoded) response. Documented. | + +## Definition of done + +- `src/httpware/client.py` exists with `AsyncClient`, `_normalize_timeout`, `_build_body`, `_UNSET`, and `_from_view`. +- `src/httpware/config.py` extends `ClientConfig` with `decoder` and `middleware` fields. +- `src/httpware/__init__.py` exports `AsyncClient` at the package root and adds it to `__all__` in alphabetic position. +- All six test files exist with the test list above; ~38 tests; all pass. +- `tests/test_client_typing.py` includes the `ty`-checked overload-validation file. +- `just test` shows the increment from the post-1-6 baseline of 208 → ~246 passed, 1 deselected, 100% line coverage on `client.py` and the extended `ClientConfig`. +- `just lint-ci` clean. +- `tests/test_no_httpx2_leakage.py` still passes. +- `tests/test_optional_extras_isolation.py` still passes. +- CHANGELOG bullet under `[Unreleased]` / `### Added` describes the public surface plus the out-of-scope items (auth, data/files, ref-counting, streaming, observability). +- Story 1-7 lands as a single PR off `main` via the branch `story/1-7-asyncclient`. From 9dd7f26e2b54d29e2a3ee0c55d7ce54de403e8ab Mon Sep 17 00:00:00 2001 From: Artur Shiriev Date: Sun, 31 May 2026 21:45:18 +0300 Subject: [PATCH 02/13] feat(story-1.7): extend ClientConfig with decoder and middleware fields MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds two new fields to ClientConfig: - decoder: ResponseDecoder (default: PydanticDecoder()) - middleware: tuple[Middleware, ...] (default: ()) Both fields have defaults so existing construction paths are unchanged. The PydanticDecoder default factory introduces a constructor-time dependency from config.py on decoders/pydantic.py — acceptable since pydantic is a hard dep.

charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the eight public HTTP method shortcuts plus the helpers they share: - _resolve_url for httpx-style base_url prefix join - _build_request for default+per-call header/param merging - _send for the dispatch + optional decode wiring - 8 methods × 2 @overload declarations each (None vs type[T] for the response_model parameter) — total 16 overload stubs - get/head/options/delete take no body params; post/put/patch add json and content (mutually exclusive — TypeError if both) - request takes a leading positional method parameter Lint-rule alignment: - json: Any is refactored to a recursive `JsonValue` type alias rather than suppressed - **kwargs: object on from_url (forwards heterogeneous args, doesn't read them) — no `Any` needed - _UNSET sentinel typed `object` instead of `Any` - `import typing` + `typing.Any` for the genuinely-heterogeneous internal `dict[str, typing.Any]` in extensions - ASYNC109 suppressed per-line on each `timeout: Timeout | float | None` parameter with a justification comment (HTTP-method config-value timeout is not asyncio.timeout territory) — global ignore avoided so future code that should use asyncio.timeout still gets caught - pylint.max-args raised to 10 globally (HTTP API methods naturally have many kwargs) 18 tests cover: URL resolution (relative, absolute, no base_url), default merging (headers, params), body resolution (json→serialized, content→passthrough, both→TypeError), per-call Content-Type override, and one parametrized test per method confirming the wire-method string.

Uses the _UNSET sentinel so None is a valid override value distinct from "not specified". Adds _from_view classmethod that bypasses __init__ to construct a view client (sets _owns_transport=False so __aexit__ is a no-op). The view's middleware chain is re-composed against the shared transport. with_options allowlist: base_url, default_headers, default_query, timeout, decoder, middleware. limits and transport are intentionally NOT overridable (both bind to the transport, which is shared). Five new wiring tests cover: middleware execution per request, view re- composes with new middleware, view inherits parent middleware when unset, view shares the transport reference, view _owns_transport is False. The previously-failing lifecycle test (view __aexit__ no-op) now passes.

Plural helpers merge mappings (incoming keys override existing); singular helpers add or replace a single entry. No validation, no header-key normalization — matches the existing `with_header` semantics from Story 1.2 (Story 2.3). - `MsgspecDecoder` opt-in `ResponseDecoder` adapter behind the `[msgspec]` extra at `httpware.decoders.msgspec`; `msgspec.json.decode(content, type=model)` in a single C-level parse pass. Accepts `msgspec.Struct`, dataclasses, attrs, NamedTuples, TypedDicts, and builtin/container types as `model` (pydantic models use `PydanticDecoder` instead). `msgspec.ValidationError` and `msgspec.DecodeError` propagate unchanged. Module import is safe without the extra (gated by `httpware._internal.import_checker.is_msgspec_installed`); only `MsgspecDecoder()` construction raises `ImportError` with an install hint when the extra is missing. `import httpware` does NOT eagerly load `msgspec` — `MsgspecDecoder` is reachable only via `from httpware.decoders.msgspec import MsgspecDecoder` (Story 1.6). +- `AsyncClient` — the v0.1.0 public surface. Construct with keyword-only `base_url`, `default_headers`, `default_query`, `timeout` (accepts `Timeout` instance, float seconds, or `None`), `limits`, `transport` (defaults to `Httpx2Transport`), `decoder` (defaults to `PydanticDecoder`), and `middleware` (`Sequence[Middleware]`, composed via `httpware._internal.chain.compose` at construction). Eight HTTP method shortcuts (`get`, `post`, `put`, `patch`, `delete`, `head`, `options`, `request`) with `@typing.overload`-based `response_model` typing — passing `response_model=type[T]` returns `T`, otherwise `Response`. Per-call overrides for `headers`, `params`, `cookies`, `timeout`; body params `json` (auto-encoded with `Content-Type: application/json`, typed as `JsonValue` recursive alias) and `content` (raw bytes; mutually exclusive). `base_url` joins with the path using an httpx-style prefix; absolute URLs (`http(s)://`) bypass. `from_url(base_url, **kwargs)` classmethod factory. Async context-manager lifecycle: the original client owns the transport and closes it on `__aexit__`; views returned by `with_options(**overrides)` share the transport and are no-ops on close. `with_options` accepts a keyword allowlist (`base_url`, `default_headers`, `default_query`, `timeout`, `decoder`, `middleware`); `limits` and `transport` are not overridable. Out of scope and deferred: `auth=` (Story 2.4), `data=`/`files=` body params, transport reference-counting, streaming (Epic 4), observability (Epic 5) (Story 1.7).

From 44d216d44f4cd33eebc4776bf09322567e7da542 Mon Sep 17 00:00:00 2001 From: Artur Shiriev Date: Sun, 31 May 2026 22:27:02 +0300 Subject: [PATCH 13/13] test(story-1.7): cover remaining with_options branches and per-call timeout Adds tests for the previously-uncovered with_options override paths (base_url, default_headers, default_query, decoder) plus a per-call timeout test that verifies `timeout=` propagates into the Request's extensions dict. Brings src/httpware/client.py to 100% line coverage, addressing the final review's coverage concern.
