Instance creation and lookup api/db/services/tenant_model_instance_service.py, api/db/joint_services/tenant_model_service.py |
create_instance now generates and stores an instance ID, then queries and returns the created record. OCR provisioning re-fetches the instance when creation returns a falsy value or an integer. |
OCR provisioning regression tests test/unit_test/api/db/joint_services/test_tenant_model_service_ensure_ocr_from_env.py |
Tests cover record-return behavior, PaddleOCR, MinerU, OpenDataLoader, and missing environment variables. Optional modules are stubbed for service imports. |

Test outcomes can depend on collection order because later tests may receive fake optional modules. Scope and restore these shims before merging.

Scope the dependency shims to each test. The top-level setup stores fake modules in the process-global sys.modules, and the entries remain after this module finishes. A later test that imports one of these modules can receive the fake object, making test results depend on collection order. Use monkeypatch.setitem(sys.modules, ...) or an equivalent context that restores the original entries and parent-package attributes after each test.

LGTM.
One suggestion: the title/description only cover the chardet test-isolation change, but the PR also carries a real production fix — TenantModelInstanceService.create_instance now returns the created record instead of Peewee's insert() row count, which is what caused the AttributeError: 'int' object has no attribute 'id' in _ensure_ocr_provider_from_env (plus the defensive re-fetch fallback). Worth adding that to the description so it shows up in the 0.27.x changelog.

This PR removes
chardetfrom the test module's fake dependency shim list.The OCR environment provisioning tests temporarily inject fake modules into
sys.modules. Keepingchardetin that list can replace the real installed module and leak the fake module into subsequent tests. Removing the shim keeps the test environment isolated and prevents unintendedchardetmodule pollution.This is a follow-up to PR #19890 and addresses the related test-isolation issue for #19887.
