This replaces hardcoded wheel URLs with a cleaner index-based approach. - Add pytorch-cpu index with explicit = true - Add torch/torchvision to [tool.uv.sources] - Add explicit torch/torchvision deps to trigger source override - Regenerate lockfile without nvidia/cuda/triton packages - Add required-environments for multi-platform support * fix: update regex to only replace name in [project] section The previous regex matched all lines starting with `name = "..."`, which incorrectly renamed the UV index `pytorch-cpu` to `langflow-nightly` during nightly builds. This caused `uv lock` to fail with: "Package torch references an undeclared index: pytorch-cpu" The new regex specifically targets the name field within the [project] section only, avoiding unintended replacements in other sections like [[tool.uv.index]]. * style: fix ruff quote style * fix: remove required-environments to fix Python 3.13 macOS x86_64 CI The required-environments setting was causing hard failures when packages like torch didn't have wheels for specific platform/Python combinations. Without this setting, uv resolves optimistically and handles missing wheels gracefully at runtime instead of failing during resolution. --------- * LE-270: Hydration and Console Log error (#11628) * LE-270: add fix hydration issues * LE-270: fix disable field on max token on language model --------- * test: add wait for selector in mcp server tests (#11883) * Add wait for selector in mcp server tests * [autofix.ci] apply automated fixes * Add more awit for selectors * [autofix.ci] apply automated fixes --------- * fix: reduce visual lag in frontend (#11686) * Reduce lag in frontend by batching react events and reducing minimval visual build time * Cleanup * [autofix.ci] apply automated fixes * add tests and improve code read * [autofix.ci] apply automated fixes * Remove debug log --------- * feat: lazy load imports for language model component (#11737) * Lazy load imports for language model component Ensures that only the necessary dependencies are required.

This mismatch caused the migration validator to block startup. Co-Authored-By: Claude Opus 4.5 * fix: add defensive migration to ensure trace.flow_id has CASCADE Adds a migration that ensures the trace.flow_id foreign key has ondelete=CASCADE. While the original migration already creates it with CASCADE, this provides a safety net for any databases that may have gotten into an inconsistent state. * fix: dynamically find FK constraint name in migration The original migration did not name the FK constraint, so it gets an auto-generated name that varies by database. This fix queries the database to find the actual constraint name before dropping it. --------- Co-authored-by: Claude Opus 4.5 --- ...a272d6669a_ensure_trace_flow_id_cascade.py | 89 +++++++++++++++++++ .../services/database/models/traces/model.py | 4 +- 2 files changed, 92 insertions(+), 1 deletion(-) create mode 100644 src/backend/base/langflow/alembic/versions/59a272d6669a_ensure_trace_flow_id_cascade.py diff --git a/src/backend/base/langflow/alembic/versions/59a272d6669a_ensure_trace_flow_id_cascade.py b/src/backend/base/langflow/alembic/versions/59a272d6669a_ensure_trace_flow_id_cascade.py new file mode 100644 index 000000000000..f6db0ff47974 --- /dev/null +++ b/src/backend/base/langflow/alembic/versions/59a272d6669a_ensure_trace_flow_id_cascade.py @@ -0,0 +1,89 @@ +"""Ensure trace.flow_id foreign key has ondelete CASCADE + +Revision ID: 59a272d6669a +Revises: 3478f0bd6ccb +Create Date: 2026-03-03 12:00:00.000000 + +Phase: EXPAND + +This is a defensive migration to ensure the trace.flow_id foreign key +has ondelete="CASCADE".

This ensures the chat scrolls to bottom even if user had scrolled up, fixing behavior where Safari's scroll fix would remain disengaged after manual scrolling.
