…sabled Details of the issue as well as local reproducers are documented in 3scale#1467. This change ensures that when `boot.init_worker` checks to see whether or not the configuration needs to be reloaded, it also checks to confirm that the `boot.ttl()` value set from `APICAST_CONFIGURATION_CACHE` is a positive number, in order to avoid an immediate and infinite recursive loop of refreshing the configuration. This should still preserve the initial fix [1] where this regression appears to have been introduced, as we should never schedule reloading with the configuration settings of: ``` APICAST_CONFIGURATION_LOADER: boot APICAST_CONFIGURATION_CACHE: -1 ``` We should also never have a situation where we'd need to account for `interval = 0` since we fail out in `boot.init` in that case [2]. Tested locally as documented in the issue, however based on the comment in the initial fix PR, I've not added any tests in code. Happy to do so if there's now a good way to accomplish that! [1] 3scale#1399 [2] https://github.com/3scale/APIcast/blob/7e7eaf6f1d584c78d999c0d09f5b65203161c402/gateway/src/apicast/configuration_loader.lua#L146-L149
Simplifies the conditional to reload configuration based on the interval set by `APICAST_CONFIGURATION_CACHE`. Also conditionally sets the interval to schedule.
