For example, the user may want to perform a 'prefetch' task every hour, or 'gc' task every day. To assist, update the 'git maintenance run' command to include a '--schedule=' option. The allowed frequencies are 'hourly', 'daily', and 'weekly'. These values are also allowed in a new config value 'maintenance..schedule'. The 'git maintenance run --schedule=' checks the '*.schedule' config value for each enabled task to see if the configured frequency is at least as frequent as the frequency from the '--schedule' argument. We use the following order, for full clarity: 'hourly' > 'daily' > 'weekly' Use new 'enum schedule_priority' to track these values numerically. The following cron table would run the scheduled tasks with the correct frequencies: 0 1-23 * * * git -C maintenance run --scheduled=hourly 0 0 * * 1-6 git -C maintenance run --scheduled=daily 0 0 * * 0 git -C maintenance run --scheduled=weekly This cron schedule will run --scheduled=hourly every hour except at midnight. This avoids a concurrent run with the --scheduled=daily that runs at midnight every day except the first day of the week. This avoids a concurrent run with the --scheduled=weekly that runs at midnight on the first day of the week. Since --scheduled=daily also runs the 'hourly' tasks and --scheduled=weekly runs the 'hourly' and 'daily' tasks, we will still see all tasks run with the proper frequencies.
