Max 5abe070ec6 Resolve harmony-one/bounties#90: Add revert mechanism for UpdateValidatorWrapper (#3939) ... * Add revert mechanism for UpdateValidatorWrapper Closes harmony-one/bounties#90 (1) Use LRU for ValidatorWrapper objects in stateDB to plug a potential memory leak (2) Merge ValidatorWrapper and ValidatorWrapperCopy to let callers ask for either a copy, or a pointer to the cached object. Additionally, give callers the option to not deep copy delegations (which is a heavy process). Copies need to be explicitly committed (and thus can be reverted), while the pointers are committed when Finalise is called. (3) Add a UpdateValidatorWrapperWithRevert function, which is used by staking txs `Delegate`, `Undelegate`, and `CollectRewards`. Other 2 types of staking txs and `db.Finalize` continue to use UpdateValidateWrapper without revert, again, to save memoery (4) Add unit tests which check a) Revert goes through b) Wrapper is as expected after revert c) State is as expected after revert * Change back to dictionary for stateValidators Since the memory / CPU usage saved is not significantly different when using an LRU + map structure, go back to the original dictionary structure to keep code easy to read and have limited modifications. * Add tests for validator wrapper reverts As requested by @rlan35, add tests beyond just adding and reverting a delegation. The tests are successive in the sense that we do multiple modifications to the wrapper, save a snapshot before each modification and revert to each of them to confirm everything works well. This change improves test coverage of statedb.go to 66.7% from 64.8% and that of core/state to 71.9% from 70.8%, and covers all the code that has been modified by this PR in statedb.go. For clarity, the modifications to the wrapper include (1) creation of wrapper in state, (2) adding a delegation to the wrapper, (3) increasing the blocks signed, and (4) a change in the validator Name and the BlockReward. Two additional tests have been added to cover the `panic` and the `GetCode` cases.		3 years ago
