Releases and Snapshots of the Timing System

Release

A Timing Firmware Release packs together new features and requirements defined in our Development Road Map,
as well as bug-fixes from previous releases. Since a Timing Firmware Release should've been tested and integrated with the rest of the Control System:

  • Bug-fixes are going to be added to the Release Candidate during the integration and testing phase.
  • Release Support in Production. Problems in Production should be reproducible in our test system and be fixed.
    These bug-fixes will be presented in the next Snapshot or Release.

Release Cycle

Our release cycle is synchronized with the CSCO Development Road Map and follows the next steps:

  1. Development Version (Alpha) tested continuously in the Timing Test Facility wip
  2. Release Candidate tested in the Timing Test Facility
  3. Deployment of Release in Production

Naming

The Releases have a name where the first letter indicates the version order according to the alphabet:

Asterisk, Balloon, Cherry, Doomsday, Enigma , F

Snapshot

A Timing Firmware Snapshot packs together the features needed for a particular user-case or particular system (e.g. CRYRING) and it doesn't go through a
completely firmware release cycle. You can see a firmware Snapshot as a Beta Version which is going to be tested in "production system" while
the development goes on, it means:
  • Best effort support. We can't guarantee that we will be able to reproduce reported bugs.
  • Bug-fixes are NOT going to be added to the Snapshot and rolled out. These bug-fixes will be included in the next Snapshot or Release.

Snapshot Cycle

The Snapshots complete a short development cycle:
  1. Snapshot Candidate tested in the Timing Test Facility
  2. Deployment in Production

Naming

The snapshots don't receive a name and are just completed with the month and year of their creation.
