fac04cb refactor: Add lock annotations to Active* methods (MacroFake) fac15ff Fix logical race in rest_getutxos (MacroFake) fa97a52 Fix UB/data-race in RPCNotifyBlockChange (MacroFake) fa530bc Add ChainstateManager::GetMutex(), an alias for ::cs_main (MacroFake) Pull request description: This fixes two issues: * A data race in `ActiveChain`, which returns a reference to the chain (a `std::vector`), which is not thread safe. See also below traceback. * A corrupt rest response, which returns a blockheight and blockhash, which are unrelated to each other and to the result, as the chain might advance between each call without cs_main held. The issues are fixed by taking cs_main and holding it for the required time. ``` ================== WARNING: ThreadSanitizer: data race (pid=32335) Write of size 8 at 0x7b3c000008f0 by thread T22

…atures in coinbase (dashpay#5752) ## Issue being fixed or feature implemented Now that we have ChainLock sigs in coinbase `VerifyDB()` have to process them. It works most of the time because usually we simply read contributions from quorum db https://github.com/dashpay/dash/blob/develop/src/llmq/quorums.cpp#L385. However, sometimes these contributions aren't available so we try to re-build them https://github.com/dashpay/dash/blob/develop/src/llmq/quorums.cpp#L388. But by the time we call `VerifyDB()` bls worker threads aren't started yet, so we keep pushing jobs into worker's queue but it can't do anything and it halts everything. backtrace: ``` * frame #0: 0x00007fdd85a2873d libc.so.6`syscall at syscall.S:38 frame #1: 0x0000555c41152921 dashd_testnet`std::__atomic_futex_unsigned_base::_M_futex_wait_until(unsigned int*, unsigned int, bool, std::chrono::duration<long, std::ratio<1l, 1l> >, std::chrono::duration<long, std::ratio<1l, 1000000000l> >) + 225 frame #2: 0x0000555c40e22bd2 dashd_testnet`CBLSWorker::BuildQuorumVerificationVector(Span<std::shared_ptr<std::vector<CBLSPublicKey, std::allocator<CBLSPublicKey> > > >, bool) at atomic_futex.h:102:36 frame #3: 0x0000555c40d35567 dashd_testnet`llmq::CQuorumManager::BuildQuorumContributions(std::unique_ptr<llmq::CFinalCommitment, std::default_delete<llmq::CFinalCommitment> > const&, std::shared_ptr<llmq::CQuorum> const&) const at quorums.cpp:419:65 frame #4: 0x0000555c40d3b9d1 dashd_testnet`llmq::CQuorumManager::BuildQuorumFromCommitment(Consensus::LLMQType, gsl::not_null<CBlockIndex const*>) const at quorums.cpp:388:37 frame #5: 0x0000555c40d3c415 dashd_testnet`llmq::CQuorumManager::GetQuorum(Consensus::LLMQType, gsl::not_null<CBlockIndex const*>) const at quorums.cpp:588:37 frame #6: 0x0000555c40d406a9 dashd_testnet`llmq::CQuorumManager::ScanQuorums(Consensus::LLMQType, CBlockIndex const*, unsigned long) const at quorums.cpp:545:64 frame #7: 0x0000555c40937629 dashd_testnet`llmq::CSigningManager::SelectQuorumForSigning(Consensus::LLMQParams const&, llmq::CQuorumManager const&, uint256 const&, int, int) at signing.cpp:1038:90 frame #8: 0x0000555c40937d34 dashd_testnet`llmq::CSigningManager::VerifyRecoveredSig(Consensus::LLMQType, llmq::CQuorumManager const&, int, uint256 const&, uint256 const&, CBLSSignature const&, int) at signing.cpp:1061:113 frame #9: 0x0000555c408e2d43 dashd_testnet`llmq::CChainLocksHandler::VerifyChainLock(llmq::CChainLockSig const&) const at chainlocks.cpp:559:53 frame #10: 0x0000555c40c8b09e dashd_testnet`CheckCbTxBestChainlock(CBlock const&, CBlockIndex const*, llmq::CChainLocksHandler const&, BlockValidationState&) at cbtx.cpp:368:47 frame #11: 0x0000555c40cf75db dashd_testnet`ProcessSpecialTxsInBlock(CBlock const&, CBlockIndex const*, CMNHFManager&, llmq::CQuorumBlockProcessor&, llmq::CChainLocksHandler const&, Consensus::Params const&, CCoinsViewCache const&, bool, bool, BlockValidationState&, std::optional<MNListUpdates>&) at specialtxman.cpp:202:60 frame #12: 0x0000555c40c00a47 dashd_testnet`CChainState::ConnectBlock(CBlock const&, BlockValidationState&, CBlockIndex*, CCoinsViewCache&, bool) at validation.cpp:2179:34 frame #13: 0x0000555c40c0e593 dashd_testnet`CVerifyDB::VerifyDB(CChainState&, CChainParams const&, CCoinsView&, CEvoDB&, int, int) at validation.cpp:4789:41 frame #14: 0x0000555c40851627 dashd_testnet`AppInitMain(std::variant<std::nullopt_t, std::reference_wrapper<NodeContext>, std::reference_wrapper<WalletContext>, std::reference_wrapper<CTxMemPool>, std::reference_wrapper<ChainstateManager>, std::reference_wrapper<CBlockPolicyEstimator>, std::reference_wrapper<LLMQContext> > const&, NodeContext&, interfaces::BlockAndHeaderTipInfo*) at init.cpp:2098:50 frame #15: 0x0000555c4082fe11 dashd_testnet`AppInit(int, char**) at bitcoind.cpp:145:54 frame #16: 0x0000555c40823c64 dashd_testnet`main at bitcoind.cpp:173:20 frame #17: 0x00007fdd85934083 libc.so.6`__libc_start_main(main=(dashd_testnet`main at bitcoind.cpp:160:1), argc=3, argv=0x00007ffcb8ca5b88, init=<unavailable>, fini=<unavailable>, rtld_fini=<unavailable>, stack_end=0x00007ffcb8ca5b78) at libc-start.c:308:16 frame #18: 0x0000555c4082f27e dashd_testnet`_start + 46 ``` Fixes dashpay#5741 ## What was done?

The removal of chainstate globals meant that whoever was calling `GetUTXOCoin` should have access to the chainstate handy. This is trivial in RPC code where `ToJson()` is used ([source](https://github.com/dashpay/dash/blob/5baa5222258f5cf2be0a3ce0f335dfd2fee931bc/src/rpc/evo.cpp#L1286)) through `Ensure`(`Any`)`Chainman`. Not the case in Qt code ([source](https://github.com/dashpay/dash/blob/5baa5222258f5cf2be0a3ce0f335dfd2fee931bc/src/qt/masternodelist.cpp#L369)), which is supposed to be given restricted access to information by the interface. As the fallback seems to be capable of fetching UTXOs and spent outputs, we can remove the `GetUTXOCoin` method and make the fallback the only method. * In `develop`, as of this writing, `CChainState` members `FlushStateToDisk` and {`Enforce`, `Invalidate`, `MarkConflicting`}`Block` were accessing their internals through the global, despite having direct access to them. As the globals they were calling are going to be bid farewell, they needed to be changed to access its members instead. The reason for going the roundabout way is unknown. * `CDSNotificationInterface` takes in a `ChainstateManager` (instead of the `CChainState` it actually requires) as at the time of interface initialization ([source](https://github.com/dashpay/dash/blob/5baa5222258f5cf2be0a3ce0f335dfd2fee931bc/src/init.cpp#L1915-L1918)), the active chainstate hasn't been loaded in yet as that happens further down ([source](https://github.com/dashpay/dash/blob/5baa5222258f5cf2be0a3ce0f335dfd2fee931bc/src/init.cpp#L1988-L1991)). As `CDSNotificationInterface::InitializeCurrentBlockTip()` is called well after it is initialized, we can resolve to the active chainstate in there. * As `GetCreditPoolDiffForBlock` requires access to `ChainstateManager` as `GetCreditPoolDiffForBlock` > `ProcessLockUnlockTransaction` > `CheckAssetLockUnlockTx` > `CheckAssetUnlockTx` > `ChainstateManager::m_blockman.LookupBlockIndex()` and `BlockAssembler` only has `CChainState`, it had to be reworked around `ChainstateManager`. ~~`CChainState` is passed as a direct argument while `ChainstateManager` can be fetched from `NodeContext`. Unlike `CTxMemPool`, which can be passed custom instances ([source](https://github.com/dashpay/dash/blob/5baa5222258f5cf2be0a3ce0f335dfd2fee931bc/src/rpc/mining.cpp#L381-L382), [source](https://github.com/dashpay/dash/blob/5baa5222258f5cf2be0a3ce0f335dfd2fee931bc/src/test/util/setup_common.cpp#L391-L392)), `CChainState`'s argument value is taken from `NodeContext::chainstate.ActiveChainstate()` and since we're now accepting `ChainstateManager` wholesale, we can dispense with accepting `CChainState` as an argument.~~ ~~Changes to that effect have been made.~~ AssumeUTXO introduces the need to be able to use different `CChainState`s, so this underlying assumption no longer holds true, the above described changes have been reverted. Asset locks code has been refactored to use `BlockManager` directly (which does come with the downside of needing to hold `cs_main` for longer than strictly necessary, this is why only asset locks uses `BlockManager` directly while other cases still benefit from having `ChainstateManager` as a whole). * `CMNHFManager::ConnectManagers` will be taking in a `ChainstateManager` pointer due to the `GetSignalsStage` > `GetForBlock` > `ProcessBlock` > `extractSignals` > `CheckMNHFTx` > `ChainstateManager::m_blockman.LookupBlockIndex()` chain. * The use of a bespoke `NodeContext` in `coinselector_tests` breaks tests if any interface call relies on a chainstate as `testNode` doesn't initialize one. For the most part, this was masked by `WalletTestingSetup` populating the chainstate globals from its own `NodeContext` even if the tests themselves preferred to use their own stripped down `testNode`. Though, removing the chainstate globals meant that they can no longer rely on `WalletTestingSetup`'s `NodeContext` to mask the barebones `testNode` global being used in the test (specifically, `addCoins` > `listMNCollaterials` > `ChainActive()` worked because `ChainActive()` accessed `WalletTestingSetup`'s `NodeContext` but when `ChainActive()` was gone and replaced with `NodeContext::chainman.ActiveChain()`, it uses `testNode`'s `ChainstateManager`, which doesn't exist, which causes it to crash). To remedy this, a5595b1 and 5e54aa9 from [bitcoin#23288](bitcoin#23288) were adapted for the limited purpose of eliminating `testNode` and using `WalletTestingSetup`'s `NodeContext` instead. This comes with the unfortunate effect of skipping a lot of the refactoring, cleanups and optimizations done before and adapting the ones after them non-trivial. It is therefore best recommended that the commit be reverted and changes implemented step-by-step in a pull request at some point in the future. For now, it's kept around here for the sake of this pull request, which, if merged, should prevent more chainstate globals use from leaking into the codebase. <details> <summary>Pre-fix crash stacktrace: </summary> ``` dash@71aecd6afb45:/src/dash$ lldb-16 ./src/test/test_dash (lldb) target create "./src/test/test_dash" Current executable set to '/src/dash/src/test/test_dash' (x86_64).
