⚠️ Post-Resolution Regression: OCI Content Item Padding (PR #68)

Warning

The automated resolver and analyzer incorrectly classified PR #68 as fully preserved. CARTO's content item padding code was silently dropped, causing production OCI streaming failures.

What was dropped

PR #68 added two defensive padding blocks to _handle_generic_stream_chunk() in litellm/llms/oci/chat/transformation.py:

  1. Tool call padding (preserved) β€” handles missing arguments, id, name in progressive tool call chunks
  2. Content item padding (DROPPED) β€” handles missing text/imageUrl fields when OCI streams TEXT or IMAGE content items

Only the tool call padding survived the merge. The content item padding (6 lines) was silently lost because upstream's Oracle PR (61fed95f8c) added similar-looking tool call code but NOT content item handling. The resolver kept upstream's version, not realizing CARTO's was a superset.

Why the pipeline missed it

Stage Failure
Resolver CARTO pattern extraction only captures def/class/async def definitions. The content item padding is inline code inside an existing function β€” invisible to pattern matching.
Analyzer Verified "tool call code exists" but didn't diff CARTO vs resolved to check ALL additions. Saw similar code and concluded "comprehensive merge" without noticing the missing content item block.

Impact

Deployed image caused Pydantic validation errors on CartoDB/cloud-native#23162 when OCI streamed TEXT chunks without a text field.

Fix

Cherry-picked 9505d65759 onto upstream-sync/v1.81.0-stable to restore the content item padding. Image rebuild required.

Recommendations

  1. Maintain the carto-features.yml manifest - This registry proved invaluable for tracking and verifying CARTO customizations
  2. Run feature verification after every sync - The manifest includes grep patterns for automated verification
  3. Consider upstreaming stable fixes - Features like JSON repair (fix: repair malformed JSON in streaming tool call argumentsΒ #54) and Azure URL handling (fix(azure): Strip operation suffixes from deployment URLs to prevent 404 errorsΒ #70) could benefit the broader LiteLLM community

Analysis completed: 2026-02-11


Feature-by-Feature Breakdown

PR #70: fix(azure): Strip operation suffixes from deployment URLs

  • Decision: πŸ”’ Preserved CARTO (high confidence)
  • Reason: CARTO's regex-based URL suffix stripping was restored in commit ee80963. The function strips operation-specific suffixes (/chat/completions, /embeddings, etc.) from Azure deployment URLs to prevent 404 errors when the SDK appends them again. Upstream v1.81.0 does not have equivalent functionality.
  • Files: litellm/llms/azure/common_utils.py, tests/test_litellm/llms/azure/test_azure_common_utils.py
  • Recommendation: Correct decision - CARTO provides essential URL normalization not present in upstream

PR #54: fix: repair malformed JSON in streaming tool call arguments

  • Decision: πŸ”’ Preserved CARTO (high confidence)
  • Reason: CARTO's _validate_and_repair_tool_arguments() function was restored in commit ee80963. Uses JSONDecoder.raw_decode() for O(n) extraction of first valid JSON object from concatenated/malformed chunks (common with Gemini streaming). Upstream v1.81.0 does not have JSON repair logic.
  • Files: litellm/litellm_core_utils/streaming_chunk_builder_utils.py, tests/test_litellm/litellm_core_utils/test_streaming_chunk_builder_utils.py
  • Recommendation: Correct decision - CARTO provides essential malformed JSON recovery not present in upstream

PR #68: fix(oci): Add tool calling support for OCI Gemini streaming

  • Decision: πŸ”’ Preserved CARTO (high confidence)
  • Reason: CARTO's OCI Gemini tool calling fix was restored in commit 29fe48b. Generates UUIDs for missing tool call IDs and adds proper tool call accumulation in streaming. Without this, OCI Gemini returns empty actions[] because tool calls with empty IDs are silently dropped.
  • Files: litellm/llms/oci/chat/transformation.py, litellm/responses/litellm_completion_transformation/streaming_iterator.py
  • Recommendation: Correct decision - CARTO fix is essential for OCI Gemini tool calling

PR #38: fix: Snowflake PAT auth and Claude streaming support

  • Decision: πŸ”’ Preserved CARTO (high confidence)
  • Reason: CARTO's Snowflake streaming handler was restored in commit b7c3c2f. Adds SnowflakeStreamingHandler for missing 'created' field and Claude-format tool_use -> OpenAI tool_calls transformation. Upstream v1.81.0 refactored class hierarchy and lost these customizations.
  • Files: litellm/llms/snowflake/chat/transformation.py
  • Recommendation: Correct decision - CARTO provides essential Snowflake streaming support

PR #58: fix: Enable Snowflake tool calling via Responses API

  • Decision: πŸ”’ Preserved CARTO (high confidence)
  • Reason: CARTO's Snowflake tool calling enhancements restored in commit b7c3c2f. Includes _transform_messages() for role='tool' messages, _transform_tool_choice() for string-to-object conversion, and default tool_choice='auto' when tools present.
  • Files: litellm/llms/snowflake/chat/transformation.py, litellm/responses/litellm_completion_transformation/transformation.py
  • Recommendation: Correct decision - CARTO provides essential Snowflake Responses API support

PR #69: fix(databricks): Handle empty delta in GPT-5 streaming responses

  • Decision: πŸ”§ Customized Upstream (high confidence)
  • Reason: The DatabricksChatResponseIterator class exists in upstream v1.81.0 but CARTO's test file verifies empty delta handling. The resolved code uses .get() for safe content access, matching CARTO's intent. Both upstream and CARTO use similar patterns.
  • Files: litellm/llms/databricks/chat/transformation.py, tests/litellm/llms/databricks/chat/test_databricks_streaming.py
  • Recommendation: Correct decision - upstream provides compatible functionality, CARTO tests verify behavior

PR #5: fix: Redis session storage for streaming Response API requests

  • Decision: πŸ”’ Preserved CARTO (high confidence)
  • Reason: CARTO's Redis session storage for streaming was restored. Adds _store_session_in_redis() to streaming iterator and _patch_store_session_in_redis() to transformation. Essential for previous_response_id context with streaming.
  • Files: litellm/responses/litellm_completion_transformation/streaming_iterator.py, litellm/responses/litellm_completion_transformation/transformation.py
  • Recommendation: Correct decision - CARTO provides essential streaming session persistence

PR #90: feat(docker): multi-arch builds (AMD64 + ARM64) for non_root image

  • Decision: πŸ”’ Preserved CARTO (high confidence)
  • Reason: CARTO's multi-architecture Docker builds restored in commit e5a9894. Creates docker-build-multiarch.yaml reusable workflow with matrix builds using native GitHub runners. Upstream has no equivalent multi-arch capability.
  • Files: .github/workflows/docker-build-multiarch.yaml, .github/workflows/carto-ghcr-deploy.yaml, .github/workflows/carto-release.yaml
  • Recommendation: Correct decision - CARTO provides essential multi-arch support for deployment

PR #55: fix: switch Docker base image to wolfi-base for Python version control

  • Decision: πŸ”§ Customized Upstream (high confidence)
  • Reason: Dockerfile.non_root uses cgr.dev/chainguard/wolfi-base as base image (CARTO customization). Upstream v1.81.0 uses similar Chainguard images. The resolved version incorporates both upstream structure improvements and CARTO's base image choice.
  • Files: docker/Dockerfile.non_root
  • Recommendation: Correct decision - appropriate merge of both approaches

PR #13: Download prisma binaries on build time

  • Decision: πŸ”§ Customized Upstream (high confidence)
  • Reason: Prisma binary pre-caching is present in resolved Dockerfile.non_root with PRISMA_BINARY_CACHE_DIR and related environment variables. This CARTO optimization for offline/egress-restricted environments is preserved alongside upstream's build improvements.
  • Files: docker/Dockerfile.non_root
  • Recommendation: Correct decision - CARTO optimization preserved within upstream structure

PR #61: fix: Azure Responses API URL construction with deployment paths

  • Decision: πŸ”§ Customized Upstream (medium confidence)
  • Reason: Azure Responses API transformation exists with deployment path handling. The resolved version includes reasoning item handling and input validation that filters status fields. Integration appears complete.
  • Files: litellm/llms/azure/responses/transformation.py
  • Recommendation: Correct decision - Azure Responses API properly integrated

PR #66: fix(responses): Fix _ENTERPRISE_ResponsesSessionHandler NameError

  • Decision: βœ… Upstream Substitutes (medium confidence)
  • Reason: This was a quick fix for a NameError that likely was addressed in upstream refactoring. The transformation.py has proper session handler integration without NameError issues.
  • Files: litellm/responses/litellm_completion_transformation/transformation.py
  • Recommendation: Correct decision - upstream resolved the underlying issue

For custom model names like gcp/google/gemini-2.5-flash, Vertex AI returned
404 because it only knows the actual model name (gemini-2.5-flash).

The fix makes the deployment lookup always run, so the custom model name

πŸ”§ Fix: Redis Session Key Mismatch (commit c284cde)

Issue

AI tests were failing with context loss errors:

  • tools-frontend-continuation: AI said tools not available
  • context-coherence: AI asked "which dataset?" instead of remembering context

Root Cause

The original CARTO Redis session patch (PR #5, commit 30ca2a38ba) had a bug in the key format:

# STORE (uses raw response_id):
name=f"litellm_patch:session:{response_id}"

# GET (decoded the ID first - WRONG):
actual_request_id = decode_previous_response_id_to_original_previous_response_id(previous_response_id)
name=f"litellm_patch:session:{actual_request_id}"

This caused sessions to be stored but never retrieved because the keys didn't match.

Fix

Removed the ID decoding on the GET side - now both store and retrieve use the same raw ID format:

# GET (now uses raw previous_response_id):
name=f"litellm_patch:session:{previous_response_id}"

Files Changed

  • litellm/responses/litellm_completion_transformation/transformation.py - Fixed _patch_get_session_from_redis() method

Verification

Docker image rebuild triggered. Re-run cloud-native integration tests after image is updated.

The Response API wasn't storing sessions in Redis for streaming requests,
only for non-streaming. This caused context to be lost when using
previous_response_id with streaming responses.

Changes:
- Add _store_session_in_redis method to streaming iterator
- Store full conversation history immediately when stream completes
- Pass litellm_completion_request to streaming iterator for message history
- Ensures streaming behaves identically to non-streaming for session storage

This fixes the timing issue where a delay was needed between requests
to allow batch processing to store sessions.

πŸ”§ Fix: Streaming Redis Session Storage (commit 4b459a8)

Issue

The Redis session storage patch was completely missing from the streaming iterator in the upstream-sync branch. This caused:

  • Streaming responses (most API calls) never stored sessions in Redis
  • AI lost context between turns because sessions weren't persisted

Root Cause

During the upstream sync conflict resolution, the streaming Redis patch from PR #5 was lost. The carto/main branch had 3 Redis references in streaming_iterator.py, but upstream-sync had 0.

Fix

Cherry-picked commit 16f77e0735 from carto/main:

  • Added litellm_completion_request parameter to streaming iterator
  • Added _store_session_in_redis() method for streaming responses
  • Handler.py now passes the completion request to streaming iterator

Files Changed

  • litellm/responses/litellm_completion_transformation/streaming_iterator.py - Added Redis session storage
  • litellm/responses/litellm_completion_transformation/handler.py - Pass completion request

Verification

Docker image will rebuild. Re-run cloud-native integration tests to verify coherence is restored.

Note: This is a fundamental CARTO feature that enables conversation context persistence for the AI Agent.

⚠️ Post-Merge Issue: OCI Content Item Padding Regression (PR #68)

What Happened

The upstream sync pipeline incorrectly classified PR #68 ("fix(oci): Add tool calling support for OCI Gemini streaming") as "Customized Upstream (high confidence)", claiming a "comprehensive merge of both codebases." In reality, only part of CARTO's code was preserved.

What was preserved: The tool call padding code (lines 1357-1367) that handles missing arguments, id, and name fields in progressive streaming tool calls.

What was silently dropped: The content item padding code (6 lines) that handles missing text/imageUrl fields when OCI streams TEXT or IMAGE content items without those fields. This code prevents Pydantic validation crashes.

Root Cause

Two pipeline stages failed:

  1. Resolver β€” CARTO pattern extraction only captures def/class/async def definitions via grep. The content item padding is an inline code block inside _handle_generic_stream_chunk(), not a new function definition, so it was invisible to pattern matching.

  2. Analyzer β€” Verified "tool call code exists" but didn't diff CARTO vs resolved to check if ALL CARTO additions were present. CARTO's version was a superset (tool calls + content items) vs upstream's version (tool calls only). The analyzer saw similar-looking code and concluded the merge was correct.

Impact

The deployed upstream-sync-v1.81.0-stable image caused OCI streaming failures in cloud-native PR CartoDB/cloud-native#23162 β€” Pydantic validation errors when OCI streamed TEXT chunks without a text field.

Fix Applied

Cherry-picked commit 9505d65759 onto upstream-sync/v1.81.0-stable, which restores the content item padding:

# Fix missing required fields in content items before Pydantic validation
if dict_chunk.get("message") and dict_chunk["message"].get("content"):
    for content_item in dict_chunk["message"]["content"]:
        if isinstance(content_item, dict):
            if content_item.get("type") == "TEXT" and "text" not in content_item:
                content_item["text"] = ""
            elif content_item.get("type") == "IMAGE" and "imageUrl" not in content_item:
                content_item["imageUrl"] = {"url": ""}

Pipeline Improvements Planned

To prevent this class of regression:

  • Add diff-based CARTO addition extraction to the resolver (not just function signatures)
  • Add superset/subset verification to both resolver and analyzer
  • Generate explicit diffs showing what CARTO added vs what's in the resolved version

See upcoming pipeline fix PR for details.

Restores the complete OCI Gemini tool calling fix (PR #68) that was
lost during the upstream sync to v1.81.0-stable.

Changes from carto/main:
- transformation.py: Generate UUIDs for missing OCI tool call IDs
  instead of empty strings (which caused silent tool call drops)
- streaming_iterator.py: Add tool call accumulation and proper
  Responses API event emission (_handle_tool_call_delta,
  _emit_function_call_done_events)

Without this fix, OCI Gemini models return empty actions[] because
tool calls with empty IDs are silently dropped during response
aggregation in stream_chunk_builder.

…, #58

Port 5 CARTO features that were silently dropped during the v1.81.0
upstream sync due to class hierarchy refactoring:

- Add SnowflakeStreamingHandler for missing 'created' field and
  Claude-format tool_use -> OpenAI tool_calls transformation
- Add _transform_messages() for role="tool" -> Snowflake content_list
- Enhance _transform_tool_choice() to convert strings to Snowflake
  object format (e.g. "auto" -> {"type": "auto"})
- Add get_model_response_iterator() override
- Default tool_choice to "auto" when tools present in Responses API

Also adds .github/carto-features.yml manifest to track critical
customizations and prevent future sync regressions.

…ortex endpoint

The upstream v1.81.0 refactored Snowflake URL construction into a two-step
build (_get_api_base + get_complete_url). When api_base already contains the
full endpoint path (e.g. from CARTO platform config), the path gets appended
twice, causing 404 errors on ded-07.

Skip path construction if api_base already contains cortex/inference:complete.

πŸ”§ CARTO Feature Fix Started

Restoring 1 incorrectly dropped CARTO feature(s).

View workflow β†’

Features restored:
- [PR #90] Multi-architecture Docker builds for non_root image

Changes:
- Created docker-build-multiarch.yaml reusable workflow with matrix builds
  for linux/amd64 (ubuntu-latest) and linux/arm64 (ubuntu-24.04-arm)
- Updated carto-ghcr-deploy.yaml to use the reusable workflow
- Fixed paths trigger (was incorrectly pointing to ghcr_carto_deploy.yaml)
- Updated carto-release.yaml to use the reusable workflow

Integration approach:
- Direct restoration of CARTO's multi-arch build capability
- No upstream equivalent existed
- Uses native GitHub runners (no QEMU emulation)
- Each arch builds natively, pushes by digest, then merges into manifest

Verified: YAML syntax validation passed

πŸ”§ CARTO Feature Fix Complete

Summary

Restored 1 CARTO feature (PR #90 multi-arch Docker builds) using systematic analysis and direct restoration

Decisions Made

PR #90: feat(docker): multi-arch builds (AMD64 + ARM64) for non_root image

Decision: CARTO's PR #90 added multi-architecture Docker build capability that was completely removed during upstream sync. The feature is independent infrastructure with no upstream equivalent. Direct restoration was performed by recreating the docker-build-multiarch.yaml workflow and updating both carto-ghcr-deploy.yaml and carto-release.yaml to use it.
Files Modified: .github/workflows/docker-build-multiarch.yaml, .github/workflows/carto-ghcr-deploy.yaml, .github/workflows/carto-release.yaml
Verification: YAML syntax validation passed for all 3 workflow files. Commit e5a9894 pushed successfully.


Next Steps:

  1. Review the changes in the Files tab
  2. CI will re-run automatically
  3. Once CI passes, the sync-ready label will be added
