In the past, jobsets which are automatically evaluated are evaluated regularly, on a schedule. This schedule means a new evaluation is created every checkInterval seconds (assuming something changed.) This model works well for architectures where our build farm can easily keep up with demand. This commit adds a new type of evaluation, called ONE_AT_A_TIME, which only schedules a new evaluation if the previous evaluation of the jobset has no unfinished builds. This model of evaluation lets us have 'low-tier' architectures. For example, we could now have a jobset for ARMv7l builds, where the buildfarm only has a single, underpowered ARMv7l builder. Configuring that jobset as ONE_AT_A_TIME will create an evaluation and then won't schedule another evaluation until every job of the existing evaluation is complete. This way, the cache will have a complete collection of pre-built software for some commits, but the underpowered architecture will never become backlogged in ancient revisions. |
