This repo hosts Spuriobot (under spuriobot/). It also includes some older manual tooling used by HF DevOps to investigate GHC CI.

About Spuriobot

Spuriobot is a service for identifying, recording, and recovering from spurious failures in CI. Currently it is specialized for GHC on https://gitlab.haskell.org.

A public dashboard powered by Spuriobot's results is found at https://grafana.gitlab.haskell.org/d/167r9v6nk/ci-spurious-failures?orgId=2&refresh=15m.

Architecturally, Spuriobot is a web service that listens to GitLab webhooks. It identifies spurious failures by searching for known strings in the build logs.

Spuriobot development

Building

Known to work:

• GHC 9.4.8 (Use GHCup to get GHC) + Cabal
• Nix + Cabal

Will probably work:

• Stack

Using the local test database

Create and start a directory-local Postgres cluster with make db. This will also create a database.

To connect to the database, specify PGHOST=$PWD/.postgres-work. E.g. to connect with psql, use PGHOST=$PWD/.postgres-work psql ci_failure

Stop the cluster with make db.stop. Remove it with make db.clean.
