Can we detect deleted accounts without listening to the system program?

[linuskendall]

Is there a way to detect deletion of accounts without a person needing to subscribe to system program?

We might need an upstream fix for this to work?

I think it's not possible, if we use owner filter then for detecting deleted accounts we also need to listen to system program :confused:

I have this issue with stake account subscription. I just see that some stake account can be deleted. On testnet at epoch 524 I get this stake account:

New stake added for: AxATCPRQUrPD2dqiepsDEftnotw4RGsvfHXnuhx1kCJu stake:StoredStake { pubkey: AxATCPRQUrPD2dqiepsDEftnotw4RGsvfHXnuhx1kCJu, stake: Delegation { voter_pubkey: 27mam831rj3b9yFbfHD8Hz5nvKVc8SrWhsGT9DfJCkwm, stake: 4998995434240, activation_epoch: 523, deactivation_epoch: 18446744073709551615, warmup_cooldown_rate: 0.25 }, last_update_slot: 220844256, write_version: 0 } 

And at epoch 525 it doesn't exit : https://explorer.solana.com/address/AxATCPRQUrPD2dqiepsDEftnotw4RGsvfHXnuhx1kCJu?cluster=testnet

As I try to reconstruct the leader_schedule from stake account, the calculus is wrong because I'm not notified of stake account deactivation. Do you think there's a way to get notified when a stake account is deleted?

I try to subscribe to solana_sdk::system_program::ID but the geyser plugin doesn't allow. I've this error: "failed to create filter: Pubkey 11111111111111111111111111111111 in filters not allowed

failed to create filter: Pubkey 11111111111111111111111111111111 in filters not allowed

this restriction is only from the plugin config, it's possible to subscribe if allowed

Ok, thanks, I didn't think about it. It's good to know.
