Steps +> use checkbox (`- [ ]`) syntax for tracking. + +**Goal:** Bring `src/oapi/client.py`'s pure-function layer (lines +109-1064: `_iter_items` through `_get_first`, i.e. everything above the +`Client` class) from 18% to essentially full coverage, per +`docs/superpowers/specs/2026-08-01-test-coverage-design.md`'s step 4 +("`client.py` argument-formatting + content-encoding"). This is the +half of `client.py` that has zero dependency on network I/O or a real +`Client` instance — pure functions and two small helper classes +(`SSLContext`, the pickling registrars) — so it is tackled before the +`Client` runtime (a later plan) and the `ClientModule` code generator +(the largest remaining chunk, also later). + +**Architecture:** Four new test files, each independently runnable and +each targeting a cohesive group of functions: + +- `tests/test_client_argument_formatting.py` — `_iter_items`, + `urlencode`, `_item_is_not_empty`, `_censor_long_json_strings`, + `_format_primitive_value`, all seven `_format_*_argument_value` style + formatters, `_format_dot_object_argument_value`, and the + `format_argument_value` dispatcher. +- `tests/test_client_request_assembly.py` — `get_request_curl`, + `_represent_http_response`, `_set_response_callback` (both of the + latter two use the real `http_test_server` from + `docs/superpowers/plans/2026-08-01-test-infrastructure.md`), + `_remove_none`, `_format_request_data`, `_get_file_name`, `_get_first`, + and `_assemble_request` (both the plain and multipart branches). +- `tests/test_client_retry_and_encoding.py` — `default_retry_hook`, + `retry`, `_encode_content`, `_decode_content`. +- `tests/test_client_pickling.py` — `_make_thread_locks_pickleable`, + `_make_http_errors_pickleable`, `_make_loggers_pickleable`, + `SSLContext`. + +Unlike the prior two plans in this initiative, every test in all four +files below was already written and independently verified against the +real library, `pytest`, `mypy --strict`, and `hatch fmt --check` *before* +this plan document was drafted (each function's real behavior was +explored live via `hatch run hatch-test.py3.10:python -` scratch +scripts, several genuine test-writing mistakes were caught and fixed +that way — see Global Constraints — and several genuine *source* bugs +were discovered and are documented as real behavior rather than +"fixed"). Because of that, each task below is a single "create/verify +this already-correct file" step rather than the incremental +per-function-group build-up used in earlier plans: there is exactly one +task per file, plus one small task to add two optional test +dependencies. This does not reduce implementer rigor — Step 2 in every +task still requires an independent `pytest`/`mypy --strict`/`hatch fmt +--check` run before committing, not a rubber-stamp. + +**Tech Stack:** Python 3.10, `pytest`, stdlib (`gzip`, `zlib`, `pickle`, +`ssl`, `logging`, `threading`, `email.message`), `sob` (already a +dependency), `zstandard`/`brotli` (newly added as `hatch-test`-env-only +test dependencies — see Task 1), `tests/servers.py`'s `http_test_server` +(Task 3 only). + +## Global Constraints + +- Line length 79 (ruff + black), enforced via `hatch fmt --check`. +- mypy strict on `tests/`: `disallow_untyped_defs`, + `disallow_incomplete_defs`, and — per this project's standing + preference — **explicit type annotations on every local variable**, + not only function signatures. Two established exceptions apply + in this plan: `with ... as name:` targets (no annotation syntax + exists there), and `Message[str, str]`-vs-`dict[str, str]` in Task 4 + (a hand-written `dict` annotation is a real mypy error against + `HTTPError`'s actual `hdrs: email.message.Message[str, str]` + parameter type — a real `email.message.Message` instance is + constructed and typed instead). All code in this plan was verified + against a real `hatch run mypy --strict --ignore-missing-imports` + run (the `default` env, which has `mypy` installed and, in this + checkout, syncs successfully — unlike in earlier plans in this + initiative, `dependence~=1.4` resolved cleanly this time; if it + doesn't for you, fall back to installing `mypy` into `hatch-test` + ad hoc and note it, don't skip the check). +- Two new **optional** test dependencies (Task 1): `zstandard` and + `brotli`/`brotlicffi`. Without them, `_encode_content`/ + `_decode_content`'s `zstd`/`br`/`dcb`/`dcz` branches are completely + untestable in the `hatch-test` environment (they were, before Task + 1 — confirmed by direct `import zstandard`/`import brotli` both + raising `ModuleNotFoundError` in a freshly-synced `hatch-test.py3.10` + env). Both packages are already listed in this project's own `zstd`/ + `brotli`/`all` optional-dependency groups (`pyproject.toml`) and are + real, supported, already-documented dependencies of `client.py`'s own + content-encoding code — this is closing a real test-environment gap, + not adding a new production dependency. +- Prefer real integration over mocks: no `unittest.mock`/`pytest-mock` + anywhere in any of the four new files. Real `gzip`/`zlib`/`zstandard`/ + `brotli` round-trips, a real `http_test_server` for the two functions + that touch an `HTTPResponse`, real `urllib.request.Request`/ + `HTTPError`/`Logger` instances throughout. The one place a real + `time.sleep` is unavoidable (`retry`'s exponential backoff) is used + as-is rather than faked — the resulting real time cost is bounded + (~6 seconds total across the whole `retry` test file, one to two + seconds per test that needs a retry) and multiple assertions were + consolidated onto a single retry attempt where possible specifically + to keep that cost down (see Task 3). +- **Imports go at the top of the file** (this project's ruff config + enforces `I001` import sorting). Run `hatch fmt --formatter` (or + `hatch fmt` without `--check`, which also auto-fixes some lint rules + like unused-ignore) followed by `hatch fmt --check` before every + commit — not optional. `hatch fmt`'s auto-formatter reflows some + function signatures (e.g. `def some_long_name() -> (\n None\n):`); + the exact code blocks in this plan already reflect the + post-`hatch fmt` output, so a byte-for-byte transcription should not + need reformatting, but run it anyway as a safety net. +- **Several verified, real, non-obvious behaviors these tests document + rather than "fix" (do not treat as bugs, do not deviate from the + specified test code trying to make them "more correct")** — all + independently traced against the real source, not assumed: + 1. `_iter_items` on a `sob.abc.Object` (e.g. `Reference`) iterates by + *property name*, not JSON key — `$ref` is exposed as the property + `ref` (since `$ref` isn't a valid Python identifier) — and yields + every declared property, including unset ones (as `None`), not + just the ones actually provided at construction time. + 2. `_format_simple_argument_value`, `_format_label_argument_value`, + and `_format_matrix_argument_value`'s exploded-dictionary branches + each do `for item in value` directly over a plain `dict`, which + yields the dict's *keys*, not `(key, value)` pairs — `item[0]`/ + `item[1]` then index into the key string itself. This silently + produces wrong output for any key of length ≥ 2 and raises + `IndexError` for any single-character key. `_format_form_ + argument_value` does not share this bug — it recognizes `dict` as + one of `_ITEMIZED_TYPES` and correctly uses `_iter_items`. + 3. `_format_deep_object_argument_value`: a dictionary entry whose + value is itself a sequence *of primitives* (e.g. `{"a": [1, 2]}`) + raises `TypeError: dict.update() argument after ** must be a + mapping, not str` — the recursive call for each primitive item + returns a plain formatted string, and the caller unconditionally + does `deep_object.update(**that_result)`. A sequence of + *dictionaries* (`{"a": [{"x": 1}]}`-shaped, or a bare top-level + sequence of dicts) does not hit this, since the recursive result + is itself a dict there. + 4. `_encode_content`'s comma-separated (`"gzip,deflate"`-style) + branch is genuinely broken for real multi-stage encoding: its + comment says "Encode content in the order provided", but the code + recursively calls `_decode_content` (not `_encode_content`) on the + still-plain input data using the *remaining* tokens before + applying the first one. For most real encoding-pair inputs this + raises (e.g. `zlib.error` when the plain data isn't actually + deflate-compressed); Task 3's test exercises the branch without + triggering the crash by using an unrecognized second token + (`"identity"`), which `_decode_content` silently no-ops on, + leaving only the first-listed encoding (`gzip`) actually applied. + `_decode_content`'s own comma branch is correct (verified via a + real two-stage `gzip` → `deflate`-compressed payload and the + matching `"gzip,deflate"` decode call) — only the encode side is + broken. + 5. `_assemble_request`'s own URL-scheme guard accepts a scheme-less + relative URL like `/relative/path` (its check only looks for a + `:` before the first `/`), but the plain, non-multipart branch + then constructs a real `urllib.request.Request(url, ...)`, which + itself raises `ValueError: unknown url type: '/relative/path'` + when the URL isn't fully qualified. Task 2's test for this + asserts a `ValueError` is raised without asserting which of the + two layers raised it (real, current, combined behavior). +- **Two lines in the pure-function layer are genuinely dead code, not + reachable via any real call graph — verified by tracing, not assumed + from a coverage report** (in the same spirit as a prior plan's + correction of a wrong "coverage.py bug" claim — see + `docs/superpowers/plans/2026-08-02-references-model-validation-tests.md`'s + Global Constraints): + - `_format_deep_object_argument_value`'s `elif isinstance(formatted_value, + typing.Iterable) and not isinstance(formatted_value, str):` branch + (lines 454-460) can only be reached via this function's own + recursive self-calls, and every such recursive call returns either + `None`, a `str` (from `_format_primitive_value`), or a `dict` (the + function's own `deep_object` return value) — never a bare list or + tuple. `None` and `str` are excluded by the `elif`'s own condition; + `dict` is caught by the itemized-type branch immediately above it. + Not covered by this plan's tests; not chased further. + - `_format_request_data`'s `if not isinstance(data, collections.abc. + MutableMapping): raise ValueError(data)` (line 842) immediately + follows `data = dict(data)` on the line above, and `dict(...)` + always produces a `dict`, which always is a `MutableMapping` — the + `raise` can never execute.

Spec coverage:** The spec's step 4 ("`client.py` argument-formatting ++ content-encoding") is fully addressed: every function in the +pure-function layer (`_iter_items` at line 109 through `_get_first` at +line 1064) has a test, across the four files. The two small +module-level helper classes/registrars that live in this same region +(`SSLContext`, the three `_make_*_pickleable` functions) are covered in +Task 5. `retry`'s exponential backoff — the one place genuine wall-clock +time is unavoidable without mocking — is tested with real timing +assertions, consolidated to minimize total real time spent. Content +encoding is tested against all four real codecs the source supports +(`gzip`, `deflate`, `zstd`, `br`, plus the `dcb`/`dcz` brotli aliases), +which required closing a real gap in the `hatch-test` environment +(Task 1) rather than skipping those branches. + +**2. Placeholder scan:** No "TBD"/"add appropriate handling"/"similar to +Task N" language. Every line of test code in every task was executed +against the real library before being written into this document — not +just once per function, but as the exact final file content, re-run +after every fix. Five genuine test-authoring mistakes were caught this +way before they ever reached this plan (two wrong expected values for +`_format_deep_object_argument_value`/`_censor_long_json_strings` in +Task 2; a `Parts`/`Headers` subscript assumption and an over-quoted +`shlex.quote` expectation in Task 3; an invalid `dict`-typed `HTTPError` +header argument in Task 5) — all fixed by re-running against the real +functions, not by adjusting the functions to match a wrong guess. Five +genuine *source* behaviors (not test bugs) were discovered and are +documented as real, current behavior in Global Constraints rather than +"corrected": three separate dict-iteration quirks shared across +`_format_simple_argument_value`/`_format_label_argument_value`/ +`_format_matrix_argument_value`, `_format_deep_object_argument_value`'s +crash on a dict-of-primitive-sequence value, `_encode_content`'s broken +comma-separated multi-encoding branch, and `_assemble_request`'s +URL-scheme guard not guaranteeing a constructible `Request`. Two lines +were traced and confirmed genuinely dead code and are explicitly left +uncovered rather than contorted around. A third line (465, the same +function's final `raise ValueError(value)` fallback) was *initially* +lumped in with those two as dead in an earlier draft — this was wrong, +caught by the opus final-branch review, and independently +re-confirmed by the controller with a live `hatch run +hatch-test.py3.10:python -` probe (`_format_deep_object_argument_value +("id", {1, 2}, explode=True)` really does raise `ValueError` at line +465, since a `set` is neither a primitive, an itemized type, nor a +`Sequence`). Rather than repeating the prior plan's mistake of leaving +a real, reachable line undertested, `test_format_deep_object_ +argument_value_rejects_a_non_sequence` was added to Task 2 (bringing +its count to 81) to cover it. This is the second time in this +initiative a "coverage gap must be dead code" claim was wrong; both +times the fix was the same — trace the real call graph (or run the +real function) rather than trust the first plausible explanation, and +when a claim turns out wrong, add the missing test rather than just +correcting the prose. + +**3.

This single black-box +pass, across the four fixtures, transitively exercises the overwhelming +majority of `ClientModule`'s ~50 private methods (parameter-style +representation, security-scheme-derived `__init__` defaults, OAuth2 +flow handling, multipart form-data assembly, polymorphic response type +resolution, method naming) at once -- confirmed by the coverage delta +in Task 8 below (56% → 83%, file-wide). A small number of the +free functions above `ClientModule` (Task 3) are additionally isolable +enough to unit-test directly. + +Five new test files: + +- `tests/test_client_module_helpers.py` -- direct unit tests for the + isolable free functions: `_get_relative_module_path`, `_get_relative_ + module_import`, `_schema_defines_model`, `_iter_path_item_operations`, + `get_default_method_name_from_path_method_operation`, `_strip_def_ + decorators`. +- `tests/test_client_module_parameter_styles.py` -- generates a real + client from `parameter-styles.json` and executes every one of its 9 + operations (path `simple`/`label`/`matrix` styles, query `form`/ + `spaceDelimited`/`pipeDelimited`/`deepObject` styles, header `simple` + style, cookie `form` style) against `http_test_server`, asserting the + real path/query/header/cookie that reaches the server. +- `tests/test_client_module_security_schemes.py` -- generates a real + client from `security-schemes.json`, asserts the generated `__init__` + bakes in the right defaults for API-key location/name and OAuth2/OIDC + URLs, and executes the API-key (header/query/cookie) and Bearer + operations end-to-end. +- `tests/test_client_module_multipart.py` -- generates a real client + from `multipart-request-body.json` and documents a real bug (see + Global Constraints). +- `tests/test_client_module_polymorphic_responses.py` -- generates a + real client from `polymorphic-schemas.json` and executes its four + operations, asserting `allOf`-merged, `oneOf`-resolved, + `anyOf`-resolved, and `additionalProperties`-dictionary responses all + deserialize to the correct real model type. + +Plus two small supporting changes: + +- `tests/conftest.py` gains a new `generated_client_package` fixture + (Task 2) -- `generated_module_loader` (from the infrastructure plan) + loads a *single* generated file, but a generated client module always + contains a package-relative `from . import model` import, so it must + be loaded as part of a real package. This fixture generates a real + model + client module pair into a real temporary package directory, + imports both, and cleans up `sys.modules`/`sys.path` afterward. +- `tests/input-data/security-schemes.json` gains one real schema (Task + 1) -- as originally authored (infrastructure plan), every response in + this fixture was a bare `{"type": "object"}` with no named + `components/schemas` entry, which triggers a real, separate + `ModelModule` bug (an empty-schema OpenAPI document generates a + `model.py` missing a needed `sob` import, raising `NameError` on + import -- out of `client.py`'s scope, noted for a future `model.py` + plan). Adding one minimal named schema (`ProtectedResource`) and + referencing it from one response unblocks generating a genuinely + loadable/runnable package from this fixture without touching + `model.py`. + +**Tech Stack:** Python 3.10, `pytest`, stdlib (`importlib`, `inspect`), +`oapi.model.ModelModule`, `oapi.client.ClientModule` (the systems under +test, used as real code generators, not mocked), `tests/servers.py`'s +`http_test_server`. + +## Global Constraints + +- Line length 79 (ruff + black), enforced via `hatch fmt --check`. +- mypy strict on `tests/`: explicit type annotations on every local + variable, per this project's standing preference. All code verified + against a real `hatch run mypy --strict --ignore-missing-imports` + run. Generated-module attribute access (`client_module.Client`, + `model_module.Pet`, etc.) is necessarily untyped -- the modules are + loaded dynamically via `importlib`, so mypy sees `ModuleType` and + treats attribute access as `Any` -- this is not a new exception to + the annotation rule, it's the same dynamic-loading pattern already + used (and already accepted by `mypy --strict`) for `generated_module_ + loader` in prior plans. +- Prefer real integration over mocks: no `unittest.mock`/`pytest-mock` + anywhere in any of the five new files. Every test in this plan + generates real source code with the real `ModelModule`/`ClientModule` + generators, executes it as a real imported Python package, and (for + four of the five files) makes real HTTP calls against the real + `http_test_server`. This is the most "real integration" plan in the + initiative so far -- no OpenAPI construct is faked; every fixture is + a real, validated `OpenAPI` document. +- **Four verified, real, currently-unfixed bugs found while validating + this plan's tests (do not deviate from the specified test code trying + to "fix" them -- document, don't correct)**: + 1. **`matrix`-style path parameters are completely broken in every + generated client.** `_represent_dictionary_parameter` (client.py) + prepends the matrix delimiter to the *dictionary key* used for + string formatting (`";id"`, since `_format_matrix_argument_value`'s + own output already includes the full `;id=value` fragment), but + the generated path template's `str.format(**{...})` placeholder + is still the bare `{id}` from the OpenAPI path -- + `"{id}".format(**{";id": ...})` cannot find an `"id"` key in + the kwargs dict it was given and raises `KeyError`. Verified live: + `client.get_path_matrix_id(id_=[1, 2, 3])` against a real + generated client raises `KeyError: \'id\'` every time. Documented + in `tests/test_client_module_parameter_styles.py`'s + `test_path_matrix_style_raises_key_error`. + 2. **A generated client cannot be instantiated with its own defaults + whenever its OpenAPI document names a multi-word OAuth2 flow** + (`authorizationCode`/`clientCredentials` -- i.e. most real-world + OAuth2 specs). `_iter_oauth2_flows` reads flow-type names via + `sob.utilities.iter_properties_values(security_scheme.flows)`, + which yields the Python-side snake_case *property* names of the + generated `OAuthFlows` model (`"authorization_code"`) rather than + the OpenAPI spec's own camelCase flow-type identifiers + (`"authorizationCode"`) that `Client.__init__`'s own validation + requires. The baked-in default `oauth2_flows` tuple therefore + fails that validation immediately on construction. Verified live: + `Client(url="http://example.com")` (no override) against a real + generated client raises `ValueError` every time; the identical + construction with an explicit, valid `oauth2_flows=(...)` succeeds. + Documented in `tests/test_client_module_security_schemes.py`'s + `test_default_oauth2_flows_value_is_invalid`; every other test in + that file works around it with an explicit override, exactly as a + real caller currently must. + 3. **Every generated multipart operation is unusable**, for the same + reason documented in the prior plan + (`docs/superpowers/plans/2026-08-02-client-runtime-tests.md`'s + Global Constraints): `_request_callback` calls `request.headers. + get("Content-encoding")` expecting ordinary `dict.get` semantics, + but a `MultipartRequest`'s custom `Headers` object re-raises + `KeyError` when the key is missing (as it always is for an + ordinary multipart request) and no `default` is passed. Verified + live against a real *generated* multipart method (not just + `Client.request()` directly, as the prior plan tested) -- + `client.post_upload(file=b"...", description="...", tags=[...])` + raises `KeyError: \'Content-encoding\'` every time. Documented in + `tests/test_client_module_multipart.py`. + 4. **A narrower, separate `ModelModule` bug** (not `ClientModule`'s; + noted here because it was discovered while building this plan's + test fixtures, and blocks generating a runnable package from an + OpenAPI document with no named `components/schemas`): the + generated `model.py`'s trailing `_POINTERS_CLASSES: dict[str, + type[sob.abc.Model]] = {}` line references `sob.abc.Model` in a + variable annotation, but when a document defines no real model + classes, `ModelModule` omits both `from __future__ import + annotations` and `import sob` from the generated file (since + nothing *else* in the file needs them) -- so that one remaining + reference raises `NameError: name \'sob\' is not defined` on + import. Worked around here (Task 1) by giving `security- + schemes.json` one real named schema rather than by fixing + `ModelModule` (out of `client.py`'s scope) -- noted for whoever + picks up the `model.py`/`ModelModule` plan next. + All four are real, reproducible defects in `oapi`, flagged directly + to the user in conversation, not just recorded here. +- **Codegen naming default worth knowing, not a bug**: `ClientModule`'s + `use_operation_id` parameter defaults to `False`, so even when an + OpenAPI operation has an explicit `operationId`, generated method + names default to being derived from the path and HTTP method instead + (`get_protected_api_key_header`, not `get_api_key_header`) -- + `get_default_method_name_from_path_method_operation` (tested directly + in Task 3) is the function responsible, and it's exercised in its + default (`use_operation_id=False`) configuration by every integration + test in this plan, matching how `ClientModule`/`write_client_module` + actually behave without an explicit override. +- **Deliberately out of scope for this plan** (diminishing returns, + chased and found not worth it): `ClientModule`'s many optional + customization parameters not exercised by a default `ClientModule(open_api, + model_path=...)` call -- `imports`, `init_decorator`, + `include_init_parameters`, `add_init_parameters`, `add_init_parameter_ + docs`, `init_parameter_defaults`/`init_parameter_defaults_source`, + `use_operation_id`, `module_docstring`, `class_docstring` -- and the + deprecated `Module`/`write_client_module` aliases. Each is a + real, independent feature, but covering all of them would mean many + more generate-and-load round trips for configuration options with no + fixture built to specifically exercise them; the coverage delta + already achieved (Task 8) demonstrates the four existing fixtures + already exercise the overwhelming majority of `ClientModule`'s real + logic. Not chased further in this plan. +- Verify commands: `hatch run hatch-test.py3.10:pytest + tests/test_client_module_helpers.py + tests/test_client_module_parameter_styles.py + tests/test_client_module_security_schemes.py + tests/test_client_module_multipart.py + tests/test_client_module_polymorphic_responses.py -v` (34 tests + total: 13 + 9 + 7 + 1 + 4). `hatch run mypy --strict + --ignore-missing-imports ` per file -- expect exactly one + pre-existing, unrelated finding on `tests/servers.py:56` + (`[str-bytes-safe]`) whenever `servers.py` is imported transitively; + nothing else. +- Commit scope: this working tree has unrelated pre-existing staged + files (`.claude/settings.json`, `.claude/skills/fableplan/SKILL.md`, + `AGENTS.md`, `.gitignore`) belonging to other work-in-progress -- + **never** include them in a commit.

Spec coverage:** The spec's step 6 ("`client.py` `ClientModule` +code generation... paired with executing generated clients against +`http_test_server`") is followed precisely -- every one of the four +purpose-built fixtures from the infrastructure plan is finally used for +its stated purpose, each generating a real client, loading it as a real +package, and executing it against the real `http_test_server`. The +free-function helpers immediately above `ClientModule` are covered +directly (Task 3) since they're genuinely isolable pure functions, +matching this initiative's established distinction between "isolable +pure logic gets a direct unit test" and "generated-source-text assembly +gets tested through its real output." + +**2. Placeholder scan:** No "TBD"/"add appropriate handling"/"similar to +Task N" language. Every line of test code, and the new `conftest.py` +fixture itself, was executed against the real generators before being +written into this document. Four genuine bugs were discovered this way +(three in `ClientModule`/`client.py`, one in `ModelModule`) and are +documented as real, current behavior rather than "fixed," each verified +by tracing the source and then confirming live against a real generated +package -- not assumed. One genuine test-authoring mistake was caught +during validation (an `isinstance(pets, list)` assertion that was wrong +because a generated array response deserializes to a real `sob.Array` +subclass, not a plain `list` -- fixed to check length/indexing instead) +before it ever reached this document. + +**3. Type consistency:** `generated_client_package` (Task 2) is the one +new fixture every other task's file depends on; its return type +(`tuple[ModuleType, ModuleType]`) is used consistently everywhere it's +consumed. `Response`/`http_test_server` continue to be imported the +same way established in every prior plan's test files touching +`tests/servers.py`. + +--- + +**Plan complete and saved to +`docs/superpowers/plans/2026-08-02-client-module-codegen-tests.md`.** +Per the standing blanket authorization for this initiative +([[feedback-autonomous-plan-execution]]), proceeding directly to +subagent-driven execution on branch `test-coverage` without further +confirmation. diff --git a/docs/superpowers/plans/2026-08-02-client-runtime-tests.md b/docs/superpowers/plans/2026-08-02-client-runtime-tests.md new file mode 100644 index 0000000..994c097 --- /dev/null +++ b/docs/superpowers/plans/2026-08-02-client-runtime-tests.md @@ -0,0 +1,1477 @@ +# Client Runtime Tests Implementation Plan + +> **For agentic workers:** REQUIRED SUB-SKILL: Use +> superpowers:subagent-driven-development (recommended) or +> superpowers:executing-plans to implement this plan task-by-task.

Verified + directly and repeatedly against a real local server (not a + network flake -- the identical configuration with `timeout=30` + succeeds every time). This means the OAuth2 client-credentials + flow and OIDC discovery are both broken by default for any + `Client` that doesn't explicitly set `timeout`. `tests/ + test_client_oauth2_flows.py` documents this with two dedicated + tests (`test_oauth2_client_credentials_flow_with_default_timeout_ + fails`, `test_get_oauth2_token_url_with_default_timeout_fails`) + asserting the real `OSError`, and uses an explicit `timeout=30` in + every other test of these two flows to get real, working coverage + of the surrounding logic (token caching, `scope`, redirect + handling) despite the bug. **This is a real functional defect in + `oapi`, flagged to the user directly -- not something this + test-only initiative fixes.** + 2. `_get_request_response_callback(error=...)`'s ERROR-level-logging + and exception-text-appending branch is real, callable code, but + grepping the whole `Client` class shows it is **never** invoked + with a real `error` argument anywhere -- `_request`'s only + `except HTTPError` handler calls `sob.errors.append_exception_ + text` directly, not through this callback. `tests/ + test_client_request_runtime.py`'s + `test_get_request_response_callback_error_path_logs_and_appends_text` + exercises it as a direct unit test of the method itself. +- **A third real bug, found during final review, and a correction to + this plan's own earlier "dead code" claim.** An earlier draft of this + plan claimed `Client._request`'s `if not isinstance(response, sob. + abc.Readable): raise TypeError(response)` (line 1919) was genuinely + dead, reasoning that `self._opener.open(...)` always returns a real + `http.client.HTTPResponse` (which always has `.read()`). **That + reasoning missed a real, reachable path**: `_assemble_request`'s + URL-scheme guard (the `http`/`https`-only check) lives *only* in its + non-multipart branch -- the multipart branch returns early via + `MultipartRequest(...)` before that guard ever runs. So a + `multipart=True` request with a non-HTTP URL (e.g. `file://...`) + reaches a real `FileHandler`, which returns a real + `urllib.response.addinfourl` -- an object `sob.abc.Readable` does + *not* recognize (its structural check requires a class-level `read` + method; `addinfourl` only proxies one through `__getattr__`). This + was caught by the opus final-branch review, independently + re-confirmed live by the controller (`Client(url="http://x").request + ("file://", "POST", data={"field": b"x"}, + multipart=True, headers={"Content-encoding": "identity"})` really + does raise `TypeError` at line 1919), and is now covered by + `test_request_rejects_a_non_readable_response` in `tests/ + test_client_request_runtime.py` (added post-review) rather than left + as a wrong "dead code" claim. This is the **third** time in this + initiative a "must be dead/unreachable" claim was wrong -- see the + same warning already recorded for the references/model-validation + plan and the client-argument-formatting plan (its line 465). Treat + this as a hard-learned, standing pattern: trace *every* branch that + could reach a given line, including branches (like `multipart=True`) + that bypass an earlier guard, before asserting something is dead. +- **A fourth real bug, found during final review: multipart requests + are completely broken.** Every `Client.request(..., multipart=True)` + call crashes with `KeyError: 'Content-encoding'`. `_request_callback` + (client.py:1514) calls `request.headers.get("Content-encoding")` + expecting ordinary `dict.get` semantics (`None` when the key is + absent), but a `MultipartRequest`'s `.headers` is a custom `Headers` + object (`src/oapi/_multipart_request.py`) whose `.get()` defaults to + a `sob.UNDEFINED` sentinel and *re-raises* `KeyError` when no + explicit `default` argument is passed and the key is missing. Since + an ordinary multipart request doesn't set a `Content-encoding` + header, this fires on essentially every real multipart upload made + through `Client.request()`. Confirmed live against a real + `http_test_server`. Documented (not fixed, per this test-only + initiative's scope) in `test_request_multipart_crashes_missing_ + content_encoding_header`, added post-review. **This is a + significant, currently-unfixed functional defect in `oapi` -- + flagged directly to the user, not just recorded here.** +- A relative `Location` header (e.g. `/token2` rather than an absolute + URL) breaks both OAuth2 flows' redirect-follow branches -- the code + uses the header value directly as the next request's full URL with + no relative-URL resolution, and `urllib.request.Request` requires an + absolute URL.

Verified + live: `exec()`-ing the generated source for a real minimal + empty-schema document raises `NameError: name 'sob' is not defined`. + This is the same bug already discovered (and worked around, via one + added fixture schema) while building the prior `ClientModule` plan -- + this plan adds the first *direct* regression test for `ModelModule` + itself. **A genuine testing subtlety was hit and corrected while + validating this test**: `compile(source, "", "exec")` + called from *inside* a test file that itself has `from __future__ + import annotations` silently inherits that future-import flag (`compile`'s + `dont_inherit` parameter defaults to `False`), which makes the + generated `_POINTERS_CLASSES` line's annotation lazy and masks the + real bug -- caught because the test failed to reproduce the error the + first time it was run, not assumed. The fix is `dont_inherit=True`, + documented in the test's own comment. +- **Deliberately out of scope for this plan** (diminishing returns, a + reasonable stopping point for the initiative's final piece): the + remaining missing lines in `_Modeler` (roughly lines 300-1650) + represent deep internal state-tracking across a ~1300-line class + (pointer/class-name bookkeeping, `$ref` resolution edge cases, + format-specific type mapping for every OpenAPI `format` value, + `_ModuleParser`'s re-generation-preserving-custom-code logic). Real + code, but reaching significantly further would mean either building + several more purpose-specific fixtures (this plan's black-box + strategy scales with fixture variety, and only one -- `polymorphic- + schemas.json` -- was available and unused for this purpose) or + unit-testing `_Modeler`'s internals directly against hand-built + partial state, which reintroduces the brittle/tautological problem + already avoided for `ClientModule`. This plan's coverage delta (Task + 4) reflects a real, if more modest, improvement -- the initiative + overall has already taken `client.py` from 16% to 83% and `model.py` + from a 69% starting point; this is a reasonable point to close out + the initiative rather than keep expanding scope. +- Verify commands: `hatch run hatch-test.py3.10:pytest + tests/test_model_module_helpers.py + tests/test_model_module_empty_schema.py + tests/test_model_module_polymorphic_schemas.py -v` (26 tests total: + 16 + 1 + 9). `hatch run mypy --strict --ignore-missing-imports ` + per file -- expect a fully clean result (no pre-existing findings; + these three files don't import `tests/servers.py`). +- Commit scope: this working tree has unrelated pre-existing staged + files (`.claude/settings.json`, `.claude/skills/fableplan/SKILL.md`, + `AGENTS.md`, `.gitignore`) belonging to other work-in-progress -- + **never** include them in a commit.

The one test needing genuine network I/O uses the real + `http_test_server` from the prior infrastructure plan. +- **Imports go at the top of the file** (this project's ruff config + enforces `I001` import sorting). Add new import lines to the existing + top-of-file block in each task, then run `hatch fmt --formatter` + (auto-sorts) followed by `hatch fmt --check` before every commit — + not optional. +- Private members are imported and called directly where that's the + only way to reach real, reachable-but-not-currently-publicly-wired + code (e.g. `_Document`, `_reference_after_unmarshal`, + `_schema_after_validate`).

The error only propagates when `recursive=False`, which + no public method currently passes. Task 3 tests both: the real, + reachable raise (calling `_Document.dereference` directly with + `recursive=False`) and the real, current swallow-and-continue + behavior (via the public `Resolver.dereference()`). + 2. `Reference.summary` and `Reference.description` are **already + pre-declared properties** on the generated `Reference` class + (confirmed via `sob.read_object_meta(Reference).properties` — + `['ref', 'summary', 'description']`), so they do *not* exercise + `_add_object_property`'s "this is a genuinely new property" + branch. Task 10 uses an `x-`-prefixed key (OpenAPI's own + convention for arbitrary extensions) instead. +- **`src/oapi/oas/model.py:6748-6749` (the `except KeyError: ref = None` + lines inside `_reference_after_unmarshal`) is dead code for + `Reference`, not a coverage-tool bug** — an earlier draft of this + plan wrongly attributed the "missing" report for these two lines to a + `coverage.py` measurement quirk. That was wrong: verified directly + (`Reference()["$ref"]` returns `None`, it does not raise `KeyError`, + because `sob` returns `None` for a declared-but-unset property rather + than raising), the `try` block's `ref = typing.cast(str, + data["$ref"])` simply assigns `None` and succeeds — the `except + KeyError:` handler never runs for this or any other `Reference` + input, since `$ref` is always a declared property on the class. + `coverage.py`'s "missing" report for 6748-6749 was accurate the whole + time. Task 10's test (`test_reference_after_unmarshal_requires_a_ref_attribute`) + still correctly asserts the real, resulting `ValueError` — only the + *mechanism* described in its docstring was wrong, and has been + corrected to match this explanation.

The spec's explicit call-out that this step needs "no +server needed except the one HTTP-`$ref` test" is followed exactly — +`http_test_server` appears only in Task 7. `resolve_reference()`, which +had zero prior coverage, is now covered in Task 5. Generated +constructor-body boilerplate elsewhere in `oas/model.py` is explicitly +and reasoned-out excluded, matching the spec's own guidance +("likely just needs a couple of targeted small fixtures... not new +infrastructure" — investigated and found not worth chasing for +tautological `self.x = x` coverage). + +**2. Placeholder scan:** No "TBD"/"add appropriate handling"/"similar to +Task N" language. Every step has runnable code, executed against the +real `oapi` package before being written here.

A third +claimed behavior — a supposed `coverage.py` line-attribution quirk for +`model.py:6748-6749` — was written into an earlier draft of this plan +based on a flawed reading of a real `coverage run`: the tool's +"missing" report for those two lines was correct all along; they are +genuinely dead code (`Reference()["$ref"]` returns `None` rather than +raising `KeyError`, so the `except KeyError:` handler never runs). This +was caught and corrected during the final whole-branch review (see the +ledger) rather than left standing — the test itself was always correct +(it asserts the real, resulting `ValueError`), only the plan's and the +test docstring's *mechanism* explanation was wrong, and both have been +fixed to match the traced, real behavior. + +**3. Type consistency:** `_openapi()` is defined once (Task 1) and +reused verbatim by every later task. Import names introduced in one +task (e.g. `Properties`, `Reference`, `Schema` in Task 2; +`OAPIReferencePointerError` in Task 4) are added to the same shared +import lines and reused without renaming. `Parameter`/`Reference` and +their corresponding `_..._after_validate`/`_..._after_unmarshal` +private functions in `tests/test_oas_model_hooks.py` are added to one +growing `from oapi.oas.model import (...)` block across Tasks 8-10, not +re-declared per task. + +--- + +**Plan complete and saved to +`docs/superpowers/plans/2026-08-02-references-model-validation-tests.md`.** +Two execution options: + +**1.

The pattern used + here is: leave `payloads = message.get_payload()` unannotated + (correct inference), `assert isinstance(payloads, list)`, then bind + the narrowed, explicitly-annotated `typed_payloads: list[Message[str, str]] = cast(...)` + for everything used afterward. +- No new dependencies — stdlib + `pytest` + `sob` only. +- Python `~=3.10`. +- Tests run with `--doctest-modules` — no ambiguous `>>>` sequences in + new test docstrings. +- Prefer real integration over mocks: no `unittest.mock`/`pytest-mock` + anywhere in either new test file. Where true non-determinism must be + made reproducible (the boundary-collision retry loop in Task 7), use + `random.seed(N)` — real randomness made deterministic — never patch + `random.choice` itself. +- **Imports go at the top of the file, grouped stdlib / third-party / + first-party (this project's ruff config enforces `I001` import + sorting).** Every task after Task 1/5 (file creation) adds new import + lines to the existing top-of-file import block. You do not need to + place them in perfect sorted order by hand — add the line(s) shown, + anywhere in a sensible existing `import`/`from` group, then run + `hatch fmt --formatter` (auto-sorts and reformats) followed by + `hatch fmt --check` (must report `All checks passed!` / + `N files already formatted`) before every commit in this plan.

A bare `git commit -m "..."` + commits everything currently staged, not just what you just added — + always commit with an explicit pathspec naming exactly the task's + files: `git commit -m "..."` (paths before `-m`). + Never `git add -A`/`.`/`-u`, never `git reset` in any form to + self-fix a mistake — if a commit's scope looks wrong, stop and report + it rather than trying to fix it with git surgery. +- Known, out-of-scope, pre-existing issue (do not fix as part of this + plan): a real `mypy --strict` run also flags + `tests/servers.py:56: error: If x = b'abc' then f"{x}" ...

The spec's approach for +`deprecated` -- test via real usage rather than a synthetic decorated +function -- is followed in Task 4.

Placeholder scan:** No "TBD"/"add appropriate handling"/"similar to +Task N" language. Every step has runnable code.

Beyond that first pass, the fully-assembled +contents of both files (all tasks combined, with explicit local-variable +annotations throughout) were placed at their real destination paths in +this checkout and verified: `hatch fmt --check` clean, a real +`mypy --strict` run clean (aside from the documented, out-of-scope +`tests/servers.py:56` issue), and a live `pytest` run of both files +together passing all 64 tests. Two real bugs were caught and fixed +during this process, not left in the plan: (a) an incorrect test +assertion (`test_part_boundary_does_not_collide_with_field_content` +originally, and incorrectly, assumed the boundary never appears in the +final rendered multipart bytes -- it does, as the delimiter -- corrected +to assert against field content instead); (b) an incorrect hand-written +annotation on `message.get_payload()`'s result (`list[object]` is not +assignable from the real `Message[str, str] | str | list[...] | Any` +union under mypy's invariant-list rules) -- corrected by leaving that +one variable to inference and casting into a separately-named, +explicitly-typed variable, which is now the documented pattern for +Tasks 9-10. + +**3. Type consistency:** `_headers`, `_data_bytes`, and `_parts` are +each defined once (Tasks 5, 7, 8 respectively) and reused verbatim by +every later task that needs them, with no re-declaration or signature +drift. Import names introduced in one task (e.g. `Part` in Task 6, +`Parts` in Task 8) are added to the same shared `from +oapi._multipart_request import (...)` line and reused by later tasks +without renaming. Every local variable across both files carries the +same annotation for the same real type every time it recurs (e.g. +`data: Data`, `part: Part`, `top: Part`, `first`/`second: bytes` appear +dozens of times across tasks, always with the same type). + +--- + +**Plan complete and saved to +`docs/superpowers/plans/2026-08-02-utilities-multipart-tests.md`.** Two +execution options: + +**1.

Concretely: + +- **Runtime HTTP behavior** (`Client`, retries, auth, encoding, + multipart) is tested against a **real local HTTP server** in the test + process — not `unittest.mock.patch`/`responses`/`requests-mock`. The + server is stdlib-only (`http.server.ThreadingHTTPServer` + + `BaseHTTPRequestHandler`) so no new dependency is needed; it runs on an + ephemeral port in a background thread, per-test, and is torn down in a + `finally`/fixture teardown. +- **Code generation** (`ClientModule`, `ModelModule`) is tested by + generating real `.py` source from real OpenAPI fixture documents, + `exec`/importing the result as an actual module, and — for the client — + instantiating the generated `Client` subclass and firing real requests + at the local test server. This is the only way to exercise the + hundreds of `_iter_*`/`_get_*` source-fragment branches: generate many + small, deliberately varied specs and assert on the *behavior* of the + generated code, with golden-file source comparison (existing + `tests/regression-data` pattern) as a secondary regression check, not + the primary assertion. +- **Pure functions with no I/O** (arg-formatting helpers, content + encode/decode, `_utilities.py`) are exercised directly with real inputs + and real codecs (`gzip`, `zlib`, `brotli`, `zstandard` — all already + optional deps of this project) — no mocking needed since there's + nothing to isolate from. +- The only place a double is arguably justified is simulating *transient + network failure* for retry tests (killing/delaying a real socket is + fiddly). Prefer a real flaky server (fails N times by real HTTP 5xx / + real connection-reset, then succeeds) over mocking `retry()`'s + internals — this is still achievable for real with a small stateful + request handler, so plan A is "real flaky server," not a mock. + +## New test infrastructure (build once, reuse everywhere) + +1. **`tests/servers.py`** — a small stdlib-only local HTTP test server: + - `class HTTPTestServer(ThreadingHTTPServer)` started on `("127.0.0.1", 0)` + (OS-assigned free port) in a `threading.Thread(daemon=True)`. + - A pluggable handler: either (a) a `RequestHandler` that records each + received request (method, path, query string, headers, body) into a + thread-safe list the test can assert against and returns a + configurable canned response, or (b) a routing handler keyed by + `(method, path)` for tests that need distinct responses per + generated-client operation. + - A context manager / pytest fixture `def http_server() -> Iterator[HTTPTestServer]` yielding the server with `.url` and `.requests` (recorded requests), used by every `Client`/`ClientModule` integration test. + - A `FlakyRequestHandler` variant for retry tests: returns real + `503`/connection-drop for the first *N* requests to a given path, + then a real `200`. + - A minimal real OAuth2 token-endpoint handler (`POST /token` reading + real `grant_type=password|client_credentials` form bodies, real + `Authorization: Basic` header, returning a real JSON access-token + payload) for the OAuth2 auth tests — this is a fake *authorization + server*, not a mock of `oapi`'s own auth code, so the client's HTTP + and parsing logic still runs for real. +2. **New minimal OpenAPI fixtures under `tests/input-data/`** — the + existing fixtures (petstore, uspto, languagetool, etc.) don't exercise + several client-generation branches at all (checked via grep): + no `matrix`/`label`/`spaceDelimited`/`pipeDelimited`/`deepObject` + parameter styles anywhere, no `multipart/form-data` request bodies, + no OAuth2 security schemes.

Verified: succeeds against a real Keycloak confidential + client with a service account. +2. **A real Keycloak realm-configuration gotcha, not an `oapi` bug**: + Keycloak 26's default "User Profile" feature requires `email`, + `firstName`, and `lastName` on a user for the direct-grant (password) + flow to consider the account "fully set up" -- a user with only a + username/password credential (no profile fields) gets a real `400 + invalid_grant: "Account is not fully set up"` from Keycloak itself, + confirmed by reproducing with raw `curl`, independent of `oapi`. + The realm fixture (below) includes a complete profile for exactly + this reason. +3. **Negative paths produce real, informative errors**: wrong password + -> real `401` `invalid_grant: "Invalid user credentials"`; wrong + client secret -> real `401` `unauthorized_client: "Invalid client or + Invalid client credentials"`. +4. **Token caching works against a real `expires_in`**: a second + `Client.request()` call reuses the cached `Authorization` header + (verified via `Client.headers["Authorization"]` equality across two + real requests), matching the existing fake-server-backed test but + now against a real token lifetime. +5. **A full end-to-end path works**: a `Client` configured for the + client-credentials flow, given `oauth2_scope="openid"`, correctly + authenticates a real request against Keycloak's own `/userinfo` + endpoint (used as a stand-in protected resource) -- proving the + token isn't just successfully parsed, but genuinely accepted by a + real resource server. +6. **Keycloak startstart-up is fast**: `start-dev --import-realm` with + the default in-memory H2 store becomes healthy in ~9-12 seconds, + confirmed repeatedly across multiple fresh container starts -- + acceptable for CI. +7. **A real Docker bind-mount gotcha, worth documenting for whoever + executes this plan**: if `docker compose up` ever runs before the + realm file exists at the expected host path, Docker silently creates + an empty *directory* at that path (both on the host and in the + container) instead of erroring -- silently breaking the realm + import with no obvious error (Keycloak just starts with an empty + realm, no import log line, no crash). The fix, if this happens, is + to `rm -rf` the wrongly-created directory and recreate the real + file. The plan's task order (create the real file, *then* first run + `docker compose up`) avoids ever hitting this, but it's worth + knowing about if a future contributor changes the file first without + realizing it might already be a stale directory. + +## Design decisions + +- **The `keycloak_url` fixture manages its own Docker Compose lifecycle + -- no manual `docker compose up` step required, by contributors or by + CI.** The session-scoped fixture first does a real reachability check + (`urllib.request.urlopen` against the realm's discovery URL, 2 second + timeout). If already reachable (someone else started it), it's used + as-is and left running. Otherwise, if `docker` is on `PATH`, the + fixture runs `docker compose up -d --wait` itself, re-checks + reachability, and tears the service back down (`docker compose + down`) at the end of the session -- but only if *this fixture* was + the one that started it, so it never stops an instance a developer + is deliberately running for their own use. If `docker` isn't + installed, or Keycloak never becomes reachable, every test depending + on the fixture is skipped rather than failed. This mirrors the + existing `test_languagetool` network-dependent-test pattern already + in this codebase (skip via a live check, don't fail), while going one + step further and self-provisioning the dependency instead of just + detecting it. The fixture makes no platform assumption -- it works + anywhere a working `docker compose` is on `PATH`, including a + contributor's local macOS or Windows machine, not just Linux. + Verified live, on macOS: a cold run (no containers running) auto + -starts Keycloak, all 7 tests pass in ~10s total, and the container is + confirmed gone afterward; a warm run (already running) reuses it in + under a second and leaves it running afterward. +- **No CI workflow changes at all (superseding an earlier version of + this design that added a dedicated `ubuntu-latest`-only job).** + `.github/workflows/test.yml`'s existing cross-platform `test` job + already runs the entire `tests/` suite across its matrix, so the new + Keycloak test file runs there automatically with no extra job, no + platform gate, and no explicit `docker compose` step: it + auto-provisions and passes on `ubuntu-latest` legs (Docker is + present), and cleanly skips wherever Docker isn't available or + compatible (`macos-latest`, and `windows-latest` unless it happens to + have a working Linux-container Docker setup). This was the simpler + design once the fixture became fully self-provisioning -- a separate + job would only have duplicated coverage the matrix already provides. +- **A new `tests/docker-compose.yml`** (not repo root, superseding an + earlier version of this design that put it at the top level) -- it + exists solely to support this test suite and isn't part of the + package's runtime or distribution, so it's scoped under `tests/` + alongside everything else that exists only for testing. The + `keycloak_url` fixture invokes it explicitly via `docker compose -f + tests/docker-compose.yml ...`, so `docker compose`'s default + discovery behavior (looking for a compose file in the current + directory) doesn't matter for automated use; a contributor invoking + it manually needs `-f tests/docker-compose.yml` too (or `cd tests` + first). +- **A new `tests/keycloak/realm.json`** (not `tests/input-data/`) -- + the existing `tests/input-data/` directory holds OpenAPI documents + (a specific, consistent fixture type consumed by `OpenAPI(...)`); a + Keycloak realm export is a different kind of fixture entirely, so it + gets its own directory rather than being mixed in. +- **A new, separate test file, `tests/test_client_keycloak_integration.py` + -- a deliberate, explained exception to the "one test file per source + module" consolidation already done for the rest of this suite.** + Every test in this file exercises `Client` (so by that rule alone it + would belong in `tests/test_client.py`), but it has a fundamentally + different operational profile than everything else in that file: it + requires an external service, is expected to skip in most + environments, and is the one place in the whole suite where `docker + compose` involvement matters.
