AI Notes

Failing Tests
None — Spark never ran. Job died during make install-dev.

What’s Wrong
uv pip install failed building dbt-core-experimental-parser==2.0.0b1 (pulled in via sqlmesh[dev] → dbt-core). Its build downloads a wheel from GitHub and got Remote end closed connection without response. Install/network flake, not a Spark bug.

Possible Fix

Rerun the job. If it keeps happening: pin/avoid that dbt-core path in CI, cache the wheel, or retry the download.

Adding retries in the Makefile so every CI job gets them.

Example

install-dev:
	@for i in 1 2 3; do \
		$(PIP) install -e ".[dev,web,slack,dlt,lsp]" ./examples/custom_materializations && exit 0; \
		echo "install-dev failed (attempt $$i/3), retrying..."; \
		sleep 5; \
	done; \
	exit 1
