2020-12-08test: Add new ChainTestingSetup and use itCarl Dong
Previously, the validation_chainstatemanager_tests test suite instantiated its own duplicate ChainstateManager on which tests were performed. This wasn't a problem for the specific actions performed in that suite. However, the existence of this duplicate ChainstateManager and the fact that many of our validation static functions reach for g_chainman, ::Chain(state|)Active means we may end up acting on two different CChainStates should we write more extensive tests in the future. This change adds a new ChainTestingSetup which performs all initialization previously done by TestingSetup except: 1. RPC command registration 2. ChainState initialization 3. Genesis Activation 4. {Ban,Conn,Peer}Man initialization Means that we will no longer need to initialize a duplicate ChainstateManger in order to test the initialization codepaths of CChainState and ChainstateManager. Lastly, this change has the additional benefit of allowing for review-only assertions meant to show correctness to work in future work de-globalizing g_chainman. In the test chainstatemanager_rebalance_caches, an additional LoadGenesisBlock call is added as MaybeReblanaceCaches eventually calls FlushBlockFile, which tries to access vinfoBlockFile[nLastBlockFile], which is out of bounds when LoadGenesisBlock hasn't been called yet. ----- Note for the future: The class con/destructor inheritance structure we have for these TestingSetup classes is probably not the most suitable abstraction. In particular, for both TestingSetup and ChainTestingSetup, we need to stop the scheduler first before anything else. Otherwise classes depending on the scheduler may be referenced by the scheduler after said classes are freed. This means that there's no clear parallel between our teardown code and C++'s destructuring order for class hierarchies. Future work should strive to coalesce (as much as possible) test and non-test init codepaths and perhaps structure it in a more fail-proof way.
