hydra-evaluator: Send statistics to statsd

Dependencies

• [2] 4JE45C3C Force creation of a new uncached eval if jobs have been removed
• [3] RX5IIZMT Use Email::MIME instead of Email::Simple
• [4] WVD3YYON hydra-evaluator: Add some debug code
• [5] X27GNHDV * Basic job info in the database.
• [6] S6OISBQ3 * Mark the "current" builds in a jobset, i.e. those corresponding to
• [7] JOYONH2K Prevent multiple builds with the same (job, outPath) tuple from being added
• [8] SS4TZXNU Distinguish between permanent evaluation errors and transient input errors
• [9] WQXF2T3D hydra-evaluator: Don't require $HYDRA_CONFIG
• [10] POPU2ATH * hydra_scheduler: use eval-jobs.
• [11] S5PV6IIM * Represent jobs explicitly in the DB.
• [12] FDE3BJAP * Refactoring.
• [13] 7ZHHVD6Q * Inputs of type "build" must now be declared explicitly.
• [14] BTOXLRG3 * Record the input containing the Nix expression (release.nix) in the
• [15] 5SHCWE7X * Prevent repeated evaluation of a jobset with the same inputs. This
• [16] QMW24O5S Add support for Guile & Guix.
• [17] 3XTHEUMP * Implemented the clone feature.
• [18] RFE6T5LG * Store jobset evaluations in the database explicitly. This includes
• [19] SRBU2RAE Warn against multiple jobs with the same name
• [20] IMQRX4MP hydra-eval-jobs: Use JSON instead of XML
• [21] LZO3C2KI * Hack around those SQLite timeouts: just retry the transaction.
• [*] N22GPKYT * Put info about logs / build products in the DB.
• [*] ZDENAYQI * email notification of evaluation errors to project owner (if desired)
• [*] RXVJFQ5A Evaluator cleanups
• [*] NI5BVF2V * In job inputs of type "build", allow the project and jobset names of
