From ba5ed26ff7067eca1c8104c9f16220f4656ee7a9 Mon Sep 17 00:00:00 2001 From: I561719 Date: Fri, 19 Jun 2026 15:58:34 +0200 Subject: [PATCH 01/37] feat(orchestration): add content filtering and prompt shield module MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Activates Azure Content Safety filtering and prompt attack detection automatically for all SAP AI Core model calls. Filtering is enabled by default when set_aicore_config() is called — no code change required by the developer. - New module sap_cloud_sdk.orchestration with: - FilteringModuleConfig: configures input/output filtering thresholds and prompt shield via ORCH_FILTER_* env vars (defaults: threshold 4, prompt_shield=True on input) - set_filtering(): programmatic override for thresholds at runtime - ContentFilteredError: raised when input or output is rejected by the content filter - extract_filter_blocked(): unwraps filter rejections embedded in LiteLLM APIConnectionError exceptions - set_aicore_config() now calls _activate_filtering() at the end, applying FilteringModuleConfig.from_env() to LiteLLM's SAP provider - Observability preserved: LiteLLM still makes the HTTP call; Traceloop/OTel instrumentation is unaffected - 41 unit tests covering serialisation, env parsing, LiteLLM patch, response detection, and set_filtering() behaviour - User guides updated in aicore/ and orchestration/; README breaking change notice added - Version bump 0.27.1 → 0.28.0 --- README.md | 7 + pyproject.toml | 2 +- src/sap_cloud_sdk/aicore/__init__.py | 11 + src/sap_cloud_sdk/aicore/user-guide.md | 51 ++++ src/sap_cloud_sdk/core/telemetry/module.py | 1 + src/sap_cloud_sdk/core/telemetry/operation.py | 3 + src/sap_cloud_sdk/orchestration/__init__.py | 107 ++++++++ .../orchestration/_litellm_patch.py | 185 ++++++++++++++ src/sap_cloud_sdk/orchestration/_models.py | 135 ++++++++++ src/sap_cloud_sdk/orchestration/exceptions.py | 39 +++ src/sap_cloud_sdk/orchestration/py.typed | 0 src/sap_cloud_sdk/orchestration/user-guide.md | 147 +++++++++++ tests/orchestration/__init__.py | 0 tests/orchestration/unit/__init__.py | 0 tests/orchestration/unit/test_models.py | 149 +++++++++++ tests/orchestration/unit/test_patch.py | 232 ++++++++++++++++++ .../orchestration/unit/test_set_filtering.py | 74 ++++++ 17 files changed, 1142 insertions(+), 1 deletion(-) create mode 100644 src/sap_cloud_sdk/orchestration/__init__.py create mode 100644 src/sap_cloud_sdk/orchestration/_litellm_patch.py create mode 100644 src/sap_cloud_sdk/orchestration/_models.py create mode 100644 src/sap_cloud_sdk/orchestration/exceptions.py create mode 100644 src/sap_cloud_sdk/orchestration/py.typed create mode 100644 src/sap_cloud_sdk/orchestration/user-guide.md create mode 100644 tests/orchestration/__init__.py create mode 100644 tests/orchestration/unit/__init__.py create mode 100644 tests/orchestration/unit/test_models.py create mode 100644 tests/orchestration/unit/test_patch.py create mode 100644 tests/orchestration/unit/test_set_filtering.py diff --git a/README.md b/README.md index da768b4b..b94159f6 100644 --- a/README.md +++ b/README.md @@ -16,6 +16,7 @@ The Python SDK offers a clean, type-safe API following Python best practices whi - **AI Core Integration** - **Audit Log Service** - **Audit Log NG** +- **Content Filtering & Prompt Shield** *(enabled by default from 0.28.0)* - **Destination Service** - **Document Management Service** - **Extensibility** @@ -26,6 +27,12 @@ The Python SDK offers a clean, type-safe API following Python best practices whi - **Data Anonymization Service** - **Print Service** +> **Breaking change in 0.28.0:** `set_aicore_config()` now automatically enables +> Azure Content Safety filtering and prompt shield for all SAP AI Core model calls. +> No code change is required.

The jailbreak prompt is taken verbatim from Microsoft Learn's Prompt Shields documentation; the self-harm prompt is left as an empty placeholder so operators can populate it from internal red-team fixtures without committing harmful content to the public repository. --- tests/aicore/integration/__init__.py | 0 tests/aicore/integration/conftest.py | 64 +++++ tests/aicore/integration/filtering.feature | 36 +++ .../aicore/integration/test_filtering_bdd.py | 218 ++++++++++++++++++ 4 files changed, 318 insertions(+) create mode 100644 tests/aicore/integration/__init__.py create mode 100644 tests/aicore/integration/conftest.py create mode 100644 tests/aicore/integration/filtering.feature create mode 100644 tests/aicore/integration/test_filtering_bdd.py diff --git a/tests/aicore/integration/__init__.py b/tests/aicore/integration/__init__.py new file mode 100644 index 00000000..e69de29b diff --git a/tests/aicore/integration/conftest.py b/tests/aicore/integration/conftest.py new file mode 100644 index 00000000..e0e5da08 --- /dev/null +++ b/tests/aicore/integration/conftest.py @@ -0,0 +1,64 @@ +"""Pytest configuration and fixtures for AI Core filtering integration tests.""" + +import os +from pathlib import Path + +import pytest +from dotenv import load_dotenv + +from sap_cloud_sdk.aicore import disable_filtering, set_aicore_config + + +_REQUIRED_VARS = [ + "AICORE_CLIENT_ID", + "AICORE_CLIENT_SECRET", + "AICORE_AUTH_URL", + "AICORE_BASE_URL", + "AICORE_RESOURCE_GROUP", + "AICORE_FILTER_TEST_MODEL", +] + + +def _load_env() -> None: + """Load .env_integration_tests from the repo root if present.""" + env_file = Path(__file__).parents[3] / ".env_integration_tests" + if env_file.exists(): + load_dotenv(env_file) + + +@pytest.fixture(scope="session", autouse=True) +def aicore_configured(): + """Load env, configure AI Core, restore unfiltered state on teardown.""" + _load_env() + missing = [k for k in _REQUIRED_VARS if not os.environ.get(k)] + if missing: + pytest.skip( + f"Missing env vars for filtering integration tests: {missing}" + ) + set_aicore_config() + yield + disable_filtering() + + +@pytest.fixture(scope="session") +def test_model() -> str: + """Model name to use in live completion calls.""" + return os.environ["AICORE_FILTER_TEST_MODEL"] + + +@pytest.fixture(autouse=True) +def reset_filtering_between_tests(): + """Each scenario opts in/out via its Given step.""" + disable_filtering() + yield + disable_filtering() + + +def pytest_configure(config): + config.addinivalue_line("markers", "integration: mark test as integration test") + + +def pytest_collection_modifyitems(config, items): + for item in items: + if "integration" in str(item.fspath): + item.add_marker(pytest.mark.integration) diff --git a/tests/aicore/integration/filtering.feature b/tests/aicore/integration/filtering.feature new file mode 100644 index 00000000..b54f1ce9 --- /dev/null +++ b/tests/aicore/integration/filtering.feature @@ -0,0 +1,36 @@ +Feature: Content filtering integration with SAP AI Core Orchestration v2 + As an SDK user + I want Azure Content Safety and Prompt Shield to apply automatically + So that harmful prompts and jailbreak attempts are blocked at the orchestration layer + + Background: + Given AI Core credentials are configured + And the test model is configured + + Scenario: Filtering OFF — benign prompt returns a completion + Given filtering is disabled + When I send the benign prompt + Then the response should contain a non-empty completion + And no ContentFilteredError is raised + + Scenario: Filtering ON with defaults — benign prompt returns a completion + Given filtering is enabled with default thresholds + When I send the benign prompt + Then the response should contain a non-empty completion + And no ContentFilteredError is raised + + Scenario: Input filter blocks a harmful prompt at STRICT threshold + Given filtering is enabled with all categories set to STRICT + When I send the self-harm test prompt + Then a ContentFilteredError is raised + And the error direction is "input" + And the error details mention "self_harm" + And the error has a non-empty request_id + + Scenario: Prompt Shield blocks a jailbreak attempt + Given filtering is enabled with prompt_shield on + When I send the jailbreak test prompt + Then a ContentFilteredError is raised + And the error direction is "input" + And the error details mention prompt_shield or jailbreak + And the error has a non-empty request_id diff --git a/tests/aicore/integration/test_filtering_bdd.py b/tests/aicore/integration/test_filtering_bdd.py new file mode 100644 index 00000000..474accc8 --- /dev/null +++ b/tests/aicore/integration/test_filtering_bdd.py @@ -0,0 +1,218 @@ +"""BDD step definitions for filtering integration tests. + +Run against a live AI Core orchestration deployment: + + AICORE_CLIENT_ID=...

Apply 'uv run ruff format' to all affected files. Drops unused imports (MagicMock, Mock, pytest) in tests/aicore/unit/test_aicore.py. - ty check: 'cast: Callable[[str], T] = int # type: ignore[assignment]' in core/env.py was rejected by CI's stricter ty. Drop the cast kwarg entirely (YAGNI — no caller passes anything other than int) and tighten TypeVar bound to int. Also resolves the integration test 'ctx.response has no attribute choices' error by typing ScenarioContext.response as Any. - Wire AICORE_FILTER_TEST_SELF_HARM_PROMPT environment variable into the integration test's AZURE_TEST_PROMPTS dict so the operator can populate the self-harm scenario via GitHub secret without committing harmful content to the public repo. Scenario still skips when the var is unset. --- src/sap_cloud_sdk/aicore/__init__.py | 1 + src/sap_cloud_sdk/aicore/filtering/_models.py | 17 +- src/sap_cloud_sdk/core/env.py | 30 +- tests/aicore/filtering/unit/test_filtering.py | 4 +- tests/aicore/filtering/unit/test_models.py | 20 +- tests/aicore/filtering/unit/test_patch.py | 71 ++- tests/aicore/integration/conftest.py | 4 +- .../aicore/integration/test_filtering_bdd.py | 39 +- tests/aicore/unit/test_aicore.py | 479 +++++++++++------- 9 files changed, 417 insertions(+), 248 deletions(-) diff --git a/src/sap_cloud_sdk/aicore/__init__.py b/src/sap_cloud_sdk/aicore/__init__.py index 9e64b350..918b6bc1 100644 --- a/src/sap_cloud_sdk/aicore/__init__.py +++ b/src/sap_cloud_sdk/aicore/__init__.py @@ -24,6 +24,7 @@ extract_filter_blocked, set_filtering, ) + logger = logging.getLogger(__name__) diff --git a/src/sap_cloud_sdk/aicore/filtering/_models.py b/src/sap_cloud_sdk/aicore/filtering/_models.py index 5cdfecc4..85fd2cea 100644 --- a/src/sap_cloud_sdk/aicore/filtering/_models.py +++ b/src/sap_cloud_sdk/aicore/filtering/_models.py @@ -7,6 +7,7 @@ from sap_cloud_sdk.core.env import read_env_bool, read_env_choice, read_env_str + class Severity(IntEnum): """Azure Content Safety severity threshold for filter rejection. @@ -81,10 +82,18 @@ def from_env(cls) -> FilteringModuleConfig | None: directions = {d.strip() for d in directions_raw.split(",") if d.strip()} thresholds = ContentFilterConfig( - hate=Severity(read_env_choice("AICORE_FILTER_HATE", _VALID_SEVERITIES, default=4)), - violence=Severity(read_env_choice("AICORE_FILTER_VIOLENCE", _VALID_SEVERITIES, default=4)), - sexual=Severity(read_env_choice("AICORE_FILTER_SEXUAL", _VALID_SEVERITIES, default=4)), - self_harm=Severity(read_env_choice("AICORE_FILTER_SELF_HARM", _VALID_SEVERITIES, default=4)), + hate=Severity( + read_env_choice("AICORE_FILTER_HATE", _VALID_SEVERITIES, default=4) + ), + violence=Severity( + read_env_choice("AICORE_FILTER_VIOLENCE", _VALID_SEVERITIES, default=4) + ), + sexual=Severity( + read_env_choice("AICORE_FILTER_SEXUAL", _VALID_SEVERITIES, default=4) + ), + self_harm=Severity( + read_env_choice("AICORE_FILTER_SELF_HARM", _VALID_SEVERITIES, default=4) + ), ) prompt_shield = PromptShieldConfig( enabled=read_env_bool("AICORE_FILTER_PROMPT_SHIELD", default=True) diff --git a/src/sap_cloud_sdk/core/env.py b/src/sap_cloud_sdk/core/env.py index 7d467329..1cb8afaa 100644 --- a/src/sap_cloud_sdk/core/env.py +++ b/src/sap_cloud_sdk/core/env.py @@ -9,9 +9,9 @@ from __future__ import annotations import os -from typing import Callable, TypeVar +from typing import TypeVar -T = TypeVar("T") +T = TypeVar("T", bound=int) _TRUTHY = frozenset({"true", "1", "yes"}) @@ -32,30 +32,24 @@ def read_env_bool(key: str, default: bool = False) -> bool: return (raw.strip().lower() in _TRUTHY) if raw is not None else default -def read_env_choice( - key: str, - choices: set[T], - default: T, - *, - cast: Callable[[str], T] = int, # type: ignore[assignment] -) -> T: - """Read an env var, parse via ``cast``, validate membership in ``choices``. +def read_env_choice(key: str, choices: set[T], default: T) -> T: + """Read an int env var, validate membership in ``choices``.

core/env.py: drop the TypeVar from read_env_choice — CI ty rejects the T→int return-value coercion even with a type-ignore directive. The only caller (filtering/_models.py) wraps the result in Severity() anyway, so the generic typing was dead weight. Function now returns plain int. - integration test 'Prompt Shield blocks a jailbreak attempt' was passing the request to Azure correctly (ContentFilteredError raised, direction input, request_id present) but my assertion looked for substring 'prompt_shield' / 'jailbreak' in the details payload. Azure's actual wire format is: {'azure_content_safety': {'user_prompt_analysis': {'attack_detected': True}}} Rewrite the assertion (and the feature-file step) to check the structured 'attack_detected: True' flag — robust to wording shifts in Azure's response and a more meaningful semantic check. --- src/sap_cloud_sdk/core/env.py | 12 ++++------ tests/aicore/integration/filtering.feature | 2 +- .../aicore/integration/test_filtering_bdd.py | 22 ++++++++++++++----- 3 files changed, 21 insertions(+), 15 deletions(-) diff --git a/src/sap_cloud_sdk/core/env.py b/src/sap_cloud_sdk/core/env.py index 1cb8afaa..75d68bed 100644 --- a/src/sap_cloud_sdk/core/env.py +++ b/src/sap_cloud_sdk/core/env.py @@ -9,9 +9,6 @@ from __future__ import annotations import os -from typing import TypeVar - -T = TypeVar("T", bound=int) _TRUTHY = frozenset({"true", "1", "yes"}) @@ -32,16 +29,15 @@ def read_env_bool(key: str, default: bool = False) -> bool: return (raw.strip().lower() in _TRUTHY) if raw is not None else default -def read_env_choice(key: str, choices: set[T], default: T) -> T: +def read_env_choice(key: str, choices: set[int], default: int) -> int: """Read an int env var, validate membership in ``choices``.

Runtime type stays Any to avoid a circular import. - aicore/filtering/__init__.py: set_filtering(config: ContentFiltering | None) takes a single positional arg. Old kwargs (hate, violence, sexual, self_harm, prompt_shield, directions) are removed. __all__ now exports the new 9-name class API; the previously-exposed ContentFilterConfig / PromptShieldConfig / FilteringModuleConfig are gone. - aicore/__init__.py: re-exports updated; 13 public names total. - test_filtering.py rewritten for the class API: TestSetFiltering covers no-args / explicit-None / explicit config / env-disable / explicit-config override / multi-filter cases. TestDisableFiltering unchanged. - test_patch.py: TestInstall fixtures and TestTransformRequest cases build ContentFiltering objects instead of FilteringModuleConfig. - test_models.py shrinks to TestSeverity (3 tests). All 749 unit tests pass + 4 integration skipped. Wire format unchanged; the live AI Core orchestration v2 endpoint sees identical JSON. --- src/sap_cloud_sdk/aicore/__init__.py | 18 +- .../aicore/filtering/__init__.py | 128 ++++-------- .../aicore/filtering/_litellm_patch.py | 4 +- src/sap_cloud_sdk/aicore/filtering/_models.py | 134 +----------- tests/aicore/filtering/unit/test_filtering.py | 88 +++++--- tests/aicore/filtering/unit/test_models.py | 193 +----------------- tests/aicore/filtering/unit/test_patch.py | 25 ++- 7 files changed, 146 insertions(+), 444 deletions(-) diff --git a/src/sap_cloud_sdk/aicore/__init__.py b/src/sap_cloud_sdk/aicore/__init__.py index 918b6bc1..d92ad83c 100644 --- a/src/sap_cloud_sdk/aicore/__init__.py +++ b/src/sap_cloud_sdk/aicore/__init__.py @@ -14,11 +14,14 @@ from sap_cloud_sdk.core.telemetry.module import Module from sap_cloud_sdk.core.telemetry.operation import Operation from .filtering import ( + AzureContentFilter, + ContentFilter, ContentFilteredError, - ContentFilterConfig, - FilteringModuleConfig, + ContentFiltering, + InputFiltering, + LlamaGuard38bFilter, OrchestrationError, - PromptShieldConfig, + OutputFiltering, Severity, disable_filtering, extract_filter_blocked, @@ -176,11 +179,14 @@ def set_aicore_config(instance_name: str = "aicore-instance") -> None: "set_aicore_config", "set_filtering", "disable_filtering", + "ContentFiltering", + "InputFiltering", + "OutputFiltering", + "AzureContentFilter", + "LlamaGuard38bFilter", + "ContentFilter", "Severity", "ContentFilteredError", "OrchestrationError", - "ContentFilterConfig", - "PromptShieldConfig", - "FilteringModuleConfig", "extract_filter_blocked", ] diff --git a/src/sap_cloud_sdk/aicore/filtering/__init__.py b/src/sap_cloud_sdk/aicore/filtering/__init__.py index 29c3b7f7..12650aa9 100644 --- a/src/sap_cloud_sdk/aicore/filtering/__init__.py +++ b/src/sap_cloud_sdk/aicore/filtering/__init__.py @@ -1,10 +1,10 @@ """SAP AI Core content filtering — Azure Content Safety + Prompt Shield.

The PR body + aicore user-guide carry the relevant migration detail; the README doesn't need release-notes-style content per change. - _litellm_patch.py: tighten 'except Exception: pass' to 'except ValueError' around the json() call only (review #10). The previous broad except would swallow logic bugs in ContentFilteredError(...) construction; the narrower catch handles only the realistic failure mode (non-JSON response body) and lets logic errors surface. Applied symmetrically to both input-filter and output-filter detection branches. Also satisfy CI's stricter ty by adding 'ty: ignore[too-many-positional-arguments]' to two deliberately-failing positional-call sites in test_filters.py (test_kwarg_only). The existing 'type: ignore[misc]' was sufficient for mypy but not for the CI ty version. --- README.md | 6 ------ .../aicore/filtering/_litellm_patch.py | 21 +++++++++++-------- tests/aicore/filtering/unit/test_filters.py | 4 ++-- 3 files changed, 14 insertions(+), 17 deletions(-) diff --git a/README.md b/README.md index 38315841..34b79457 100644 --- a/README.md +++ b/README.md @@ -27,12 +27,6 @@ The Python SDK offers a clean, type-safe API following Python best practices whi - **Data Anonymization Service** - **Print Service** -> **Breaking change in 0.28.0:** `set_aicore_config()` now automatically enables -> Azure Content Safety filtering and prompt shield for all SAP AI Core model calls. -> No code change is required.

After commit 3e3edb7, CI reported 6 errors at sites where I had removed 'ty: ignore[...]' directives but 'uv run ty' locally said the directives were unused. After re-adding them, CI then reported them as unused warnings — flapping.

Fallback is opt-in: set_aicore_config() does not enable it; the developer activates it explicitly via set_fallbacks() or by setting AICORE_FALLBACK_ENABLED=true and AICORE_FALLBACK_MODELS / _CONFIG. The litellm SAP provider already builds modules as a list when fallback_sap_modules is present in optional_params. The SDK now injects that kwarg from the active FallbackConfig via the existing transport patch. Refactor filtering/filters.py to host both concerns in a single subclass, OrchestrationPatchConfig (FilteringOrchestrationConfig kept as alias): - _install split into _install_filter + _install_fallback sharing _apply_patch(); _install retained as alias for back-compat. - transform_request now injects fallback_sap_modules before super(), and BROADCASTS filtering to every module entry (was modules[0] only). - transform_response attaches response.intermediate_failures from the body so callers can inspect which preferences were skipped. Non-streaming only in v1; streaming surfacing is deferred. Tests: - 35 new unit tests across test_fallback_config.py, test_patch.py and test_set_fallbacks.py covering dataclass shape, env parsing, patch injection, filtering broadcast, intermediate_failures attachment, and install lifecycle composition with filtering. - New BDD fallback.feature + test_fallback_bdd.py with 4 scenarios (primary success, primary unsupported -> fallback used, filtering composition, streaming + fallback). conftest skips cleanly when AICORE_FALLBACK_TEST_* env vars are missing. - Bump expected enum count for AICORE_SET_FALLBACKS. Docs & ops: - user-guide.md gains a Model Fallback (opt-in) section with programmatic and env-driven examples, composition with filtering, and the v1 streaming limitation. - .env_integration_tests.example documents the new AICORE_FALLBACK_TEST_PRIMARY_MODEL / _FALLBACK_MODEL secrets. --- .env_integration_tests.example | 11 + src/sap_cloud_sdk/aicore/__init__.py | 9 + src/sap_cloud_sdk/aicore/fallback/__init__.py | 9 + src/sap_cloud_sdk/aicore/fallback/fallback.py | 227 +++++++++++ src/sap_cloud_sdk/aicore/filtering/filters.py | 120 +++++- src/sap_cloud_sdk/aicore/user-guide.md | 100 +++++ src/sap_cloud_sdk/core/telemetry/operation.py | 1 + tests/aicore/fallback/__init__.py | 0 tests/aicore/fallback/unit/__init__.py | 0 .../fallback/unit/test_fallback_config.py | 170 ++++++++ tests/aicore/fallback/unit/test_patch.py | 385 ++++++++++++++++++ .../fallback/unit/test_set_fallbacks.py | 70 ++++ tests/aicore/integration/conftest.py | 58 ++- tests/aicore/integration/fallback.feature | 32 ++ tests/aicore/integration/test_fallback_bdd.py | 179 ++++++++ tests/core/unit/telemetry/test_operation.py | 6 +- 16 files changed, 1346 insertions(+), 31 deletions(-) create mode 100644 src/sap_cloud_sdk/aicore/fallback/__init__.py create mode 100644 src/sap_cloud_sdk/aicore/fallback/fallback.py create mode 100644 tests/aicore/fallback/__init__.py create mode 100644 tests/aicore/fallback/unit/__init__.py create mode 100644 tests/aicore/fallback/unit/test_fallback_config.py create mode 100644 tests/aicore/fallback/unit/test_patch.py create mode 100644 tests/aicore/fallback/unit/test_set_fallbacks.py create mode 100644 tests/aicore/integration/fallback.feature create mode 100644 tests/aicore/integration/test_fallback_bdd.py diff --git a/.env_integration_tests.example b/.env_integration_tests.example index 2bb1903b..2536ca75 100644 --- a/.env_integration_tests.example +++ b/.env_integration_tests.example @@ -33,6 +33,17 @@ AICORE_MODEL=anthropic--claude-3-5-haiku AICORE_FILTER_TEST_MODEL=sap/gpt-4o-mini AICORE_FILTER_TEST_SELF_HARM_PROMPT= +# AI CORE fallback integration tests (tests/aicore/integration/fallback.feature) +# AICORE_FALLBACK_TEST_PRIMARY_MODEL: sap/* model name that the orchestration +# server reports as unsupported in your deployed region.

The parent package marker already covers the subpackage transitively, but the one-marker-per-subpackage convention is what docs/GUIDELINES.md prescribes. --- src/sap_cloud_sdk/aicore/fallback/py.typed | 0 1 file changed, 0 insertions(+), 0 deletions(-) create mode 100644 src/sap_cloud_sdk/aicore/fallback/py.typed diff --git a/src/sap_cloud_sdk/aicore/fallback/py.typed b/src/sap_cloud_sdk/aicore/fallback/py.typed new file mode 100644 index 00000000..e69de29b From 865c0aa942f320d24ea62c40fbe5d5c8a214f33f Mon Sep 17 00:00:00 2001 From: I561719 Date: Wed, 24 Jun 2026 13:53:05 +0200 Subject: [PATCH 34/37] chore: bump version to 0.30.0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit main advanced to 0.29.0 since we last rebased (commit 101492b on main). Our 0.28.1 would fail the 'Check Version Bump' CI job which requires strictly greater than main. Going to 0.30.0 (minor) rather than 0.29.1 (patch) — this PR adds substantive new public API (ContentFiltering / InputFiltering / OutputFiltering / AzureContentFilter / LlamaGuard38bFilter classes; set_filtering / disable_filtering entry points; Severity enum; AICORE_FILTER_* env-var protocol).

We should separate concerns, like create a config.py and put the env var fetching code, and models.py for the classes.' Match the sibling-module convention (agent_memory, destination, etc.): - _models.py: Severity enum + provider classes (ContentFilter, AzureContentFilter, LlamaGuard38bFilter) + direction containers (InputFiltering, OutputFiltering, ContentFiltering). No behaviour beyond construction and to_dict() serialisation. - config.py: load_from_env() function + private _read_env_* helpers. Replaces ContentFiltering.from_env() classmethod with a module-level factory, matching agent_memory/config.py's load_from_env_or_mount() shape. - _patch.py: FilteringOrchestrationConfig, _install, _active_cfg, _ORIGINAL_CONFIG — the LiteLLM transport monkeypatch. - _api.py: set_filtering, disable_filtering, extract_filter_blocked decorated with @record_metrics. Honours the earlier review #12 ('not good pattern to keep logic on init'). - __init__.py: thin re-export surface (the 12 public names) + module-layout doc. filters.py deleted. Test imports updated to the new module paths; mock paths in test_patch.py point at _patch.GenAIHubOrchestrationConfig. ContentFiltering.from_env() classmethod removed in favour of load_from_env() — callers (tests + _api.py) updated accordingly. --- .../aicore/filtering/__init__.py | 20 +- src/sap_cloud_sdk/aicore/filtering/_api.py | 116 ++++ src/sap_cloud_sdk/aicore/filtering/_models.py | 218 +++++++ src/sap_cloud_sdk/aicore/filtering/_patch.py | 171 +++++ src/sap_cloud_sdk/aicore/filtering/config.py | 129 ++++ src/sap_cloud_sdk/aicore/filtering/filters.py | 617 ------------------ tests/aicore/filtering/unit/test_filtering.py | 10 +- tests/aicore/filtering/unit/test_filters.py | 4 +- tests/aicore/filtering/unit/test_modules.py | 19 +- tests/aicore/filtering/unit/test_patch.py | 19 +- 10 files changed, 675 insertions(+), 648 deletions(-) create mode 100644 src/sap_cloud_sdk/aicore/filtering/_api.py create mode 100644 src/sap_cloud_sdk/aicore/filtering/_models.py create mode 100644 src/sap_cloud_sdk/aicore/filtering/_patch.py create mode 100644 src/sap_cloud_sdk/aicore/filtering/config.py delete mode 100644 src/sap_cloud_sdk/aicore/filtering/filters.py diff --git a/src/sap_cloud_sdk/aicore/filtering/__init__.py b/src/sap_cloud_sdk/aicore/filtering/__init__.py index 2f0ad6ff..35fc95ba 100644 --- a/src/sap_cloud_sdk/aicore/filtering/__init__.py +++ b/src/sap_cloud_sdk/aicore/filtering/__init__.py @@ -8,14 +8,22 @@ See :mod:`sap_cloud_sdk.aicore` user guide for the documented public API. -This module is a thin re-export surface; the public API + LiteLLM transport -patch live in :mod:`.filters`.

This branch had been rebased on a pre-merge iteration that used _api.py/_models.py, exported extract_filter_blocked, and lacked completion.py. Realign to the merged form so the fallback diff against origin/main contains only fallback concerns. Restore filtering/ to origin/main state: - Bring back filters.py (from _api.py rename), models.py (from _models.py rename), config.py imports fixed accordingly. - Drop the public extract_filter_blocked symbol — the private _parse_input_filter_error stays in filters.py where main placed it. - Drop AICORE_EXTRACT_FILTER_BLOCKED from telemetry.operation. - Bring in completion.py + its unit tests from origin/main; wire completion/acompletion into aicore.__init__ exports. - Restore tests/aicore/filtering/unit/test_models.py (from test_filters.py rename) and tests/aicore/integration/test_filtering_bdd.py from main. - Update the 'Handle blocked requests' section in user-guide.md to match the wrapper-based pattern main documents. Filtering _patch.py gains one small hook (~15 lines): _install defers to fallback when its config is active, so set_filtering / disable_filtering calls while fallback is installed update filtering state without clobbering our OrchestrationPatchConfig class. Lazy import of the fallback module avoids a circular dependency at package import. Test-count assertion in tests/core/unit/telemetry/test_operation.py adjusted 153 -> 152 (removed EXTRACT + kept SET_FALLBACKS).
