Feb 2026 monthly summary for apache/incubator-devlake focusing on deployment analytics improvements. Implemented an Accurate Deployment FinishedDate for GithubDeployment to improve deployment lifecycle accuracy and reporting. Changes preserved backward compatibility while enabling precise duration calculations and better metrics. Key highlights include: a FinishedDate field in GithubDeployment, derived FinishedDate from deployment statuses (priority: latest SUCCESS, else latest terminal), and using FinishedDate in domain conversion for duration calculations. This enhances deployment timing accuracy without altering existing status semantics. Additionally, a dedicated migration was added to create a nullable finished_date column, ensuring smooth rollout and historical data compatibility. The deployment-related domain and tooling were extended to consume the new FinishedDate, and end-to-end tests were updated to cover the new logic. Tests and e2e snapshots were adjusted to validate the correct FinishedDate and duration calculations. Business value: improved visibility into deployment lifecycles, faster incident triage, and more reliable analytics for CI/CD pipelines. Technical achievements: schema migrations, domain model enhancements, GraphQL/tool updates, and expanded test coverage.
