Paul van Tilburg	cf77dbb5e7	Refactor maps cache to hold lock as short as possible ... This makes the response time way more snappy when the maps thread is updating its cache. * Move the `MapsHandle` type to the `maps` module * SWitch to using the standard library mutex * Split refresh methods into retrieval methods that don't need the lock and check timestamp & update methods that only need it shortly * Introduce the `MapsRefresh` trait and implement it for `MapsHandle` * Reorder some methods for clarity * Small documentation fixes	2022-02-13 11:22:02 +01:00
Paul van Tilburg	9b9b1a5f77	Refactor so that no static is necessary for the maps cache ... * Replace the lazy `once_cell` by a maps handle type * Use Rocket's managed state to manage a handle * Ensure that the handlers have access to it * Pass another handle to the maps updater loop * Try to keep the lock as short as possible Still, long downloads block the lock. Add a FIXME to refactor this so the lock is only taken when updating the maps fields.	2022-02-12 21:35:58 +01:00
