2022-07-18indexes, refactor: Remove CChainState use in index CommitInternal methodRyan Ofsky
Replace CommitInternal method with CustomCommit and use interfaces::Chain instead of CChainState to generate block locator. This commit does not change behavior in any way, except in the (m_best_block_index == nullptr) case, which was added recently in https://github.com/bitcoin/bitcoin/pull/24117 as part of an ongoing attempt to prevent index corruption if bitcoind is interrupted during startup. New behavior in that case should be slightly better than the old behavior (skipping the entire custom+base commit now vs only skipping the base commit previously) and this might avoid more cases of corruption.

This commit does not change behavior in any way.
2022-07-18indexes, refactor: Pass Chain interface instead of CChainState class to indexesRyan Ofsky

2020-12-07refactor: Get rid of more redundant chain methodsRussell Yanofsky
This just drops three interfaces::Chain methods replacing them with other calls. Motivation for removing these chain methods: - Need to get rid of findFirstBlockWithTimeAndHeight for #10102, which doesn't support overloaded methods - Followup from https://github.com/bitcoin/bitcoin/pull/16426#discussion_r412487403 - phantomcircuit comments about findNextBlock test http://www.erisian.com.au/bitcoin-core-dev/log-2020-06-06.html#l-214 Behavior is not changing in any way here. A TODO comment in ScanForWalletTransactions was removed, but just because it was invalid (see https://github.com/bitcoin/bitcoin/pull/19195#discussion_r448020762), not because it was implemented.
2020-09-22Add 'sequence' zmq publisher to track all block (dis)connects, mempool deltasGregory Sanders
Using the zmq notifications to avoid excessive mempool polling can be difficult given the current notifications available. It announces all transactions being added to mempool or included in blocks, but announces no evictions and gives no indication if the transaction is in the mempool or a block. Block notifications for zmq are also substandard, in that it only announces block tips, while all block transactions are still announced. This commit adds a unified stream which can be used to closely track mempool: 1) getrawmempool to fill out mempool knowledge 2) if txhash is announced, add or remove from set based on add/remove flag 3) if blockhash is announced, get block txn list, remove from those transactions local view of mempool 4) if we drop a sequence number, go to (1) The mempool sequence number starts at the value 1, and increments each time a transaction enters the mempool, or is evicted from the mempool for any reason, including block inclusion. The mempool sequence number is published via ZMQ for any transaction-related notification. These features allow for ZMQ/RPC consumer to track mempool state in a more exacting way, without unnecesarily polling getrawmempool. See interface_zmq.py::test_mempool_sync for example usage.
2020-08-27refactor: Move wallet methods out of chain.h and node.hRussell Yanofsky
Add WalletClient interface so node interface is cleaner and don't need wallet-specific methods. The new NodeContext::wallet_client pointer will also be needed to eliminate global wallet variables like ::vpwallets, because createWallet(), loadWallet(), getWallets(), etc methods called by the GUI need a way to get a reference to the list of open wallets if it is no longer a global variable. Also tweaks splash screen registration for load wallet events to be delayed until after wallet client is created.
2020-08-13Add loadwallet and createwallet RPC load_on_startup optionsRussell Yanofsky
This maintains a persistent list of wallets stored in settings that will automatically be loaded on startup. Being able to load a wallet automatically on startup will be more useful in the GUI when the option to create wallets is added in #15006, but it's reasonable to expose this feature by RPC as well.

2020-05-15wallet: Minimal fix to restore conflicted transaction notificationsRussell Yanofsky
This fix is a based on the fix by Antoine Riard <ariard@student.42.fr> in https://github.com/bitcoin/bitcoin/pull/18600. Unlike that PR, which implements some new behavior, this just restores previous wallet notification and status behavior for transactions removed from the mempool because they conflict with transactions in a block. The behavior was accidentally changed in two `CWallet::BlockConnected` updates: a31be09bfd77eed497a8e251d31358e16e2f2eb1 and 7e89994133725125dddbfa8d45484e3b9ed51c6e from https://github.com/bitcoin/bitcoin/pull/16624, causing issue https://github.com/bitcoin/bitcoin/issues/18325. The change here could be improved and replaced with a more comprehensive cleanup, so it includes a detailed comment explaining future considerations.

2020-04-30[wallet] Remove locked_chain from CWallet, its RPCs and testsAntoine Riard
This change is intended to make the bitcoin node and its rpc, network and gui interfaces more responsive while the wallet is in use. Currently because the node's cs_main mutex is always locked before the wallet's cs_wallet mutex (to prevent deadlocks), cs_main currently stays locked while the wallet does relatively slow things like creating and listing transactions. This commit only remmove chain lock tacking in wallet code, and invert lock order from cs_main, cs_wallet to cs_wallet, cs_main. must happen at once to avoid any deadlock. Previous commit were only removing Chain::Lock methods to Chain interface and enforcing they take cs_main. Remove LockChain method from CWallet and Chain::Lock interface.

FoundBlock class allows interfaces::Chain::findBlock to return more block information without having lots of optional output parameters. FoundBlock class is also used by other chain methods in upcoming commits. There is mostly no change in behavior. Only exception is CWallet::RescanFromTime now throwing NonFatalCheckError instead of std::logic_error.
