feat(gcs): Implement google gcp bucket provider - #1138
Conversation
- Added GCSBucketProvider for handling Google Cloud Storage (GCS) operations, including signed URL generation. - Introduced GCSClient to manage GCS client instances with default bucket support. - Created a global bucket-provider registry to resolve and manage different bucket providers. - Implemented tests for GCS bucket provider functionality, including signed URL generation and credential handling. - Enhanced attachment resolution to support GCS URIs, allowing for both native and signed URL handling based on provider type. - Updated documentation to reflect changes in bucket provider architecture and functionality.

In `@backend/app/models/llm/constants.py`:
- Around line 45-50: Update the TextProvider type alias to remove
Provider.GOOGLE_GCP, since GoogleGCPProvider.execute only supports
speech-to-text and text-to-speech while text requests are mapped to an
unsupported native path. Preserve the existing OpenAI, Google, and Anthropic
providers.
In `@backend/app/services/assessment/api/batch.py`:
- Around line 329-342: Extract the repeated Google Cloud credential lookup into
a shared _google_gcp_credential helper and replace both lookup blocks in the
provider-building flows with it. Pass LLMProvider.GOOGLE_GCP to
get_provider_credential instead of the literal string, while preserving the
existing dict validation and 404 HTTPException behavior.
In `@backend/app/services/assessment/utils/attachments.py`:
- Around line 75-78: Update the attachment-resolution logic around resolved.get
and split_attachment_urls to emit a warning whenever a gs:// URI has no resolved
entry, while preserving the existing fallback value for the payload. Prefix the
warning with the enclosing function name in square brackets and do not include
the URI or other object-path details in the log.
In `@docs/wiki/modules/assessment.md`:
- Line 36: Update the documentation reference for VertexBatchProvider in the
Gemini-family batch provider description to use core/batch/google_gcp.py instead
of core/batch/vertex.py; leave the provider mappings and surrounding details
unchanged.
In `@docs/wiki/modules/platform.md`:
- Line 15: Update the Bucket providers documentation entry to describe signed
URL generation via BaseBucketProvider.to_public_url, removing the
“private-to-public URLs” wording and the incorrect attribution to
providers/gcs.py; retain the existing GCS signed/bulk-signed URL details.

In `@backend/app/services/buckets/providers/gcs.py`:
- Around line 102-110: Update GCSBucketProvider.get_bulk_signed_urls to delegate
bulk signing to BaseBucketProvider via super(), removing the duplicated
dictionary-comprehension loop while preserving the existing method signature and
behavior.
- Line 14: Replace the private _load_platform_sa_info dependency in the GCS
provider with a public loader symbol, either by promoting and renaming the
existing loader in google_gcp or moving it to a shared credentials helper;
update all callers and imports to use the public API consistently.
In `@backend/app/services/buckets/providers/registry.py`:
- Around line 36-39: Rename the class method supported_providers to
list_supported_providers, preserving its return value and implementation, and
update all references and callers to use the new name.
- Around line 87-92: Update the RuntimeError raised in the get_bucket_provider
exception handler to explicitly chain the caught exception with from e,
preserving the original cause while retaining the existing logging behavior.
In `@backend/app/tests/assessment/test_api_batch.py`:
- Around line 1004-1007: Add an assertion in the Vertex provider test verifying
that VertexBatchProvider.from_credentials was called with the expected model
keyword argument, while preserving the existing provider-name and config
assertions.

and provider fixtures, annotate the fixture parameters, and add None return

annotations to test_rewrites_gcs_leaves_https_untouched and
test_no_gcs_returns_rows_unchanged_without_resolving; do not use Any.
- Around line 108-118: Update the result-key assertions in
test_falls_back_to_line_order_without_key to use the existing BATCH_KEY symbol
instead of hard-coded "custom_id" literals, while preserving the expected
line-order values "0" and "1".
In `@backend/app/tests/services/buckets/test_gcs.py`:
- Around line 105-133: Add a test in TestGetSignedUrl covering the
generate_signed_url failure path: configure blob.generate_signed_url to raise an
exception, call provider.get_signed_url, and assert that the call raises
CloudStorageError.
In `@backend/app/tests/services/buckets/test_registry.py`:
- Around line 70-98: Extend the get_bucket_provider tests with one case where
get_provider_credential returns a non-dict value and one where create_client
raises a non-ValueError exception. Assert the non-dict credential path raises
the expected validation error and the client failure is wrapped as RuntimeError,
while preserving existing ValueError behavior.

I’ll remove _load_platform_sa_info(). Since the GCS bucket provider is an abstract class, it shouldn’t be responsible for knowing which type of key needs to be resolved. The credentials should be passed in as a parameter, and the provider should simply resolve and use them. It shouldn’t need to know whether the credentials are BYOK or a platform-level key.

Make missing question_id handling consistent for every trace.
The new continue skips only later traces with None. The earlier check still raises when the first trace has None or "". A later "" value is grouped under an empty key. The result therefore depends on trace order and representation.
Apply one policy to the full input. Either reject any missing ID before grouping, or filter all missing values, including None and "".

Preserve the dataset category before applying the default.
The current fast response builder does not include category in its result. Therefore, response.get("category") is falsy for chunks produced by this code, and every fast-evaluation trace receives DEFAULT_CATEGORY, even when the dataset metadata contains a real category.
Copy the category from the dataset item metadata into the response result. Omit the trace field when the source has no category, or apply the default only if that is the documented API contract.

Normalize missing question_id values in the metadata branch.
The new initial value is None, but the metadata branch still uses .get("question_id", ""). A trace with metadata but no question ID therefore becomes "", while a trace without metadata remains None. Downstream grouping handles these values differently.
Use .get("question_id") and normalize empty strings to None.

Reject an empty credential payload during request validation.
credential: {} passes this validator. update_creds_for_org then rejects it with "Provider and credential must be provided" before it calls parse_provider_credentials. The changed API test expects "Missing required fields for openai", so this request will not produce the asserted validation error.
Call parse_provider_credentials when the normalized payload is empty, while continuing to allow non-empty partial PATCH payloads.

Return None when no output language is requested.
The surrounding code defaults output_language to "", so this assignment stores an empty string as TextContent.language_code. The shared contract in backend/app/models/llm/request.py:191-196 defines this field as optional, and backend/app/services/llm/providers/google_gcp.py uses None when the parameter is absent. Consumers can therefore receive inconsistent language metadata.
Use output_language or None.
