We currently offer four visually distinct types of build variants on master:
- The builders with a leading ! in the display name, which have variant names that end with -required. This pattern indicates a required builder.
- The builders with a leading * in the display name, which have variant names that end with -suggested. This pattern indicates a builder that is suggested when a patch build warrants additional coverage beyond what the usual -required builders offer.
- The builders with a leading ~ in the display name, which do not have any pattern to the variant name. In general, these have been intended for "experiments" or for "non-release" builds.
- The builders with no special leading sigil.
The situation with the -required and -suggested variants is mostly consistent and reasonable, but the situation with the remaining variants is far less regular. For instance:
- Most of the *SAN variants are currently tagged with ~, but these aren't really experiments at all. They are real builders and have been around for years.
- We have no consistent annotation either in the display name or the variant name which indicates that a variant is a release variant (e.g., something that "leaves the building"), or that it isn't.
There are a few things we could do to help make things more orderly:
- We could reinterpret ~ to mean non-shipping (as perhaps it originally did), and tag all non-shipping releases with ~ in the display name and prefix the variant name with noship- or nopush- or similar.
- We could tag all shipping releases with RELEASE in the display name and prefix the variant name with release-, to clearly identify which builders are release builders. As we would then have a clear way to identify releases, we could refine the meaning of ~ to truly mean "experiment", and remove the ~ sigil from the builders that aren't experiments, like ASAN.
Other schemes or modifications are certainly possible.
