This makes a number of changes:
- Get rid of the verification_progress argument in the node interface
NotifyHeaderTip (it was always 0.0).
- Instead of passing a CBlockIndex* in the UI interface's NotifyHeaderTip,
send separate height, timestamp fields. This is becuase in headers presync,
no actual CBlockIndex object is available.
- Add a bool presync argument to both of the above, to identify signals
pertaining to the first headers sync phase.
This introduces an insignificant performance penalty, as it means locator
construction needs to use the skiplist-based CBlockIndex::GetAncestor()
function instead of the lookup-based CChain, but avoids the need for
callers to have access to a relevant CChain object.
- make the code easier to read and understand
- improve performance by avoiding unnecessary move operations
- the cleaner, simpler, and easier to read the code is, the
better chance the compiler has at implementing it well
as the classes themselves are private, and to be consistent within all the
*Impl classes in src/node/interfaces.cpp and src/wallet/interfaces.cpp
following this order:
public:
// ... virtual methods ...
// ... nonvirtual helper methods ...
// ... data members ...
and add documentation in src/node/interfaces.cpp and src/wallet/interfaces.cpp
to help future reviewers and contributors.
fa32b1bbfd refactor: Use chainman() helper consistently in ChainImpl (MacroFake)
Pull request description:
Doing anything else will just lead to more verbose and inconsistent code.
ACKs for top commit:
fanquake:
ACK fa32b1bbfd - all instances of `Assert(m_node.chainman)` in node/interfaces replaced with `chainman()`, which is the same thing.

817326a828 wallet: avoid rescans if under the snapshot (James O'Beirne)
Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11) (parent PR: #15606)
---
Refuse to load a wallet if it requires a rescan lower than the height of assumed-valid blocks.
Of course in live code right now, `BLOCK_ASSUMED_VALID` block index entries don't exist since they're a unique flag introduced by the use of UTXO snapshots, so this is prophylactic code exercised only by unittests.

Code review ACK 817326a828. This seems like the simplest change we can make to avoid wallet problems when an assumeutxo snapshot is loaded.

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.
