internal: track starting of tasks
Update exported TaskState to include a "started" boolean. Record the task started state in the database and show a different icon in the UI. Tracking started enables several improvements. This change improves resuming of workflows to mark tasks that started without finishing as incomplete. This will prevent workflows resuming from an unknown state, where a task may not be safe to resume by default, such as sending a public announcement. Also, this change makes minor tweaks to the UI for task ordering, putting the most recently updated tasks at the top of the list. It also fixes a minor but confusing bug around retrying "approval" tasks. Updates golang/go#53382 Change-Id: Icff1c0df541a6e11a7bb0ab55beef60cd18a074a Reviewed-on: https://go-review.googlesource.com/c/build/+/417221 Reviewed-by: Dmitri Shuralyov <dmitshur@golang.org> Reviewed-by: Heschi Kreinick <heschi@google.com> Reviewed-by: Dmitri Shuralyov <dmitshur@google.com> TryBot-Result: Gopher Robot <gobot@golang.org> Run-TryBot: Jenny Rakoczy <jenny@golang.org> Auto-Submit: Jenny Rakoczy <jenny@golang.org>
