Subject: Re: [pbs-devel] [PATCH proxmox-backup] datastore: remove datastore from internal cache based on maintenance mode
Date: Thu, 29 Feb 2024 18:13:31 +0100 [thread overview]

Tested this thoroughly and it works as advertised!
Just some small nits inline:
> impl MaintenanceMode {
> + /// Used for deciding weather the datastore is cleared from the internal cache after the last
Small typo: weather -> whether
> + // remove datastore from cache iff last task finished
> + // and datastore is in a maintenance mode that says it should be
Did something get cut off here? The sentence doesn't sound correct...
> + let remove_from_cache = last_task
> + && pbs_config::datastore::config()
> + .and_then(|(s, _)| s.lookup::<DataStoreConfig>("datastore", &self.name()))
`self.name()` is enough here, we don't need `&self.name()`
> + pub fn update_datastore_cache() -> Result<(), Error> {
> + let (config, _digest) = pbs_config::datastore::config()?;
> + for (store, (_, _)) in &config.sections {
> + let datastore: DataStoreConfig = config.lookup("datastore", &store)?;
`store` is already a &String, we don't need to write `&store`
> + if datastore

> + .map_or(false, |m| m.clear_from_cache())

Same here

> Operation::Read => task.active_operations.read += count,
> Operation::Write => task.active_operations.write += count,
> Operation::Lookup => (), // no IO must happen there
> };
> + updated_active_operations = task.active_operations.clone();
You can remove the `.clone()` call here
