Balrog and Scheduled Changes¶
Balrog can let you schedule changes in advance through its Scheduled Changes UI
RelEng is responsible for reviewing the scheduled change to ensure that the mechanics are correct. Most notably, the mapping, fallbackMapping, and backgroundRate need to be verified.
RelMan is responsible for reviewing the scheduled change to ensure that the shipping time is correct and to authorize that the release may be shipped. If circumstances change (eg, we discover a bug we’re not willing to ship) after they sign off, they must revoke their signoff in Balrog.
After the Scheduled Change has been created, the Balrog UI will look something like:
When RelEng reviews it, they will look at the Mapping, Fallback Mapping, and Background Rate (circled above). If everything looks good, they will click on the “Signoff as…” button and be presented with a dialog like:
After they make their Signoff, the primary UI will reflect that:
RelMan and QE will go through a similar process. Once they make their Signoffs the primary UI will reflect that as well:
Now that the Signoff requirements have been met, the Scheduled Change will be enacted at the prescribed time.
