feat: add new vendors support for copyoffload testing #252
Conversation
WalkthroughConfiguration schema expanded to support multiple storage vendors (NetApp ONTAP, Hitachi Vantara, Pure Storage, Dell PowerFlex/PowerMax, and others) with vendor-specific fields. Core validation and credential-handling logic refactored to dynamically map vendor-to-field relationships instead of hardcoded ontap-specific handling. Test documentation updated to reflect broader vendor support. Changes

- Around line 943-953: Extract the local supported_vendors list into a
module-level constant (e.g., SUPPORTED_VENDORS) and replace the inline list in
the fixture with that constant; also update the vendor_specific_fields
dictionary keys (or its creation) to reference SUPPORTED_VENDORS so the vendor
set is defined once and reused (ensure the constant name is exported/available

74-98: LGTM! Clear vendor documentation added.The expanded docstring accurately documents vendor-specific required fields and aligns with the
vendor_specific_fieldsmapping inconftest.py. The reference to.providers.json.examplefor detailed configuration is helpful.
231-238: LGTM!Docstring updates are consistent with the thin migration test and provide appropriate vendor guidance.
366-372: LGTM!Consistent vendor documentation updates across all copy-offload test functions.
.providers.json.example (1)
28-78: LGTM! Comprehensive vendor configuration documentation.The documentation clearly lists all 9 supported vendors with their required fields and provides actionable instructions on how to obtain vendor-specific values (e.g., Pure Storage cluster prefix from
storageclusterCR, PowerFlex system ID from ConfigMap). This will significantly reduce configuration errors for users.conftest.py (3)
954-963: LGTM! Good balance of validation and forward compatibility.The approach of raising an error for missing vendor but only warning for unknown vendors is sensible - it allows new vendors to be tested before being formally added to the list while still alerting users to potential misconfiguration.
LOW: Static analysis flagged the long exception message (TRY003). This is a minor style consideration; the descriptive message is appropriate here for configuration errors.
972-989: LGTM! Clean and extensible vendor configuration mapping.The tuple structure
(config_key, secret_key, required)is self-documenting and the mapping is easily extensible for new vendors. The reference to forklift populator source code provides good traceability.
991-1003: LGTM! Correct dynamic field population logic.The iteration correctly handles the vendor-specific fields: adding values to secret data when found, and raising a clear error with remediation guidance when a required field is missing. The check
if storage_vendor in vendor_specific_fieldsproperly skips unknown vendors (which already received a warning above).LOW: Static analysis flagged f-string logging at line 997 (G004). Consider using
%sstyle if strict linting is enforced, but this is a minor style preference.

🧹 Nitpick | 🔵 Trivial
MEDIUM: Consider extracting supported_vendors to a module-level constant.
The vendor list is effectively duplicated since vendor_specific_fields dictionary keys contain the same values. Extracting to a constant enables reuse and ensures consistency if vendors are added/removed.

Document environment variable naming convention for vendor-specific fields in get_copyoffload_credential function.
The function correctly implements env var naming as COPYOFFLOAD_{credential_name.upper()}, converting vantara_hostgroup_id_list → COPYOFFLOAD_VANTARA_HOSTGROUP_ID_LIST. However, the docstring in utilities/copyoffload_migration.py only documents that "environment variables take precedence" but does not explain HOW env var names are constructed from credential names. Additionally, the test docstrings document basic env vars (e.g., COPYOFFLOAD_STORAGE_HOSTNAME, COPYOFFLOAD_ONTAP_SVM) but omit Vantara-specific ones like COPYOFFLOAD_VANTARA_HOSTGROUP_ID_LIST.
Why: Users setting up Vantara storage need to know the exact env var names to override config file values, especially since field names with underscores (e.g., vantara_hostgroup_id_list) map to uppercase env vars with underscores preserved.
Fix: Update get_copyoffload_credential docstring to explicitly state: "Environment variable names are constructed as COPYOFFLOAD_{credential_name.upper()} (e.g., 'storage_hostname' → 'COPYOFFLOAD_STORAGE_HOSTNAME')." Update test docstrings to list all vendor-specific env vars supported.
