/api/config/set re-parses yaml into a brand new FrigateConfig instead of
|
||
|
|
mutating the old one, so any reference captured during startup goes stale
|

|
|
the first time a user saves. Anything that has to build something after
|
||
|
|
startup, most importantly the watchdog factories that rebuild a crashed
|

|
|
process, must read through a holder rather than close over a config
|
||
|
|
object, or the rebuilt process comes back with the config as it was at
|
||
|
|
boot and silently discards every change made since.
|
||
|
|
|
||
|
|
There is deliberately no setter on the read side: the swap runs in exactly
|
||
|
|
one place (frigate.api.config_util.swap_runtime_config) and everyone else
|
||
|
|
only reads.
