rCOMM687ca39ad777: [services] consistently return when trying to remove non-existent item

Summary

Depends on D3990

Raised in https://phabricator.ashoat.com/D3990#112037

We should be consistent and throw if someone tries to remove an item that does not exist. That clearly means the logic's invalid.

Test Plan

cd services
yarn run-tunnelbroker-service
yarn test-blob-service-dev-mode
yarn test-backup-service-dev-mode

I think ideally the changes in services/tunnelbroker/src/Database/DatabaseManager.cpp would've been applied in D3990. See feedback here

That clearly means the logic's invalid.

No. It might also mean that we tried to delete the same item twice, which is fine. Take a C++ map as an example: when we erase an item twice, it doesn't throw an error.

We can consider returning some info about the presence of an item, but I still wouldn't call this an error.

This revision now requires changes to proceed.May 12 2022, 2:42 AM

Hmm, maybe you're right. I'm going to wait until we have terms in D3990. Then we can either land or abandon this one.

return instead of throwing

I'm not a big fan of silently returning if expected items do not exist but accepting this as we agreed before in D3990.
