This is a step toward removing the Chain::Lock class and reducing cs_main
locking.
This change only affects behavior in the case where wallet last block processed
falls behind the chain tip, where it will treat the last block processed as the
current tip.

This is a step toward removing the Chain::Lock class and reducing cs_main
locking.
This change only affects behavior in the case where wallet last block processed
falls behind the chain tip, where it may set a different lock time.
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.
This change affects behavior in a few small ways.
- If there's no max_height specified, percentage progress is measured ending at
wallet last processed block instead of node tip
- More consistent error reporting: Early check to see if start_block is on the
active chain is removed, so start_block is always read and the triggers an
error if it's unavailable
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.
This change only affects behavior in the case where wallet last block processed
falls behind the chain tip. The rescanblockchain error height error checking
will just be stricter in this case and only accept values up to the last
processed height
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.
This change only affects behavior in the case where wallet last block processed
falls behind the chain tip. Previously listsinceblock might not have returned
all transactions up to the claimed "lastblock" value in this case, resulting in
race conditions and potentially missing transactions in cases where
listsinceblock was called in a loop like

This is a step toward removing the Chain::Lock class and reducing cs_main

This change only affects behavior in the case where wallet last block processed
falls behind the chain tip, in which case the "Block not found in chain" error
will be stricter and not allow importing data from a blocks between the wallet
last processed tip and the current node tip.
This is a step toward removing the Chain::Lock class and reducing cs_main
locking.
It also helps ensure the GUI display stays up to date in the case where the
node chain height runs ahead of wallet last block processed height.
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.
41b0baf43c gui: Handle WalletModel::unload asynchronous (João Barbosa)
ab31b9d6fe Fix wallet unload race condition (Russell Yanofsky)
Pull request description:
This PR consists in two fixes. The first fixes a concurrency issues with `boost::signals2`. The second fixes a wallet model destruction while it's being used.
From boost signal documentation at https://www.boost.org/doc/libs/1_72_0/doc/html/signals2/thread-safety.html:
> When a signal is invoked by calling signal::operator(), the invocation first acquires a lock on the signal's mutex. Then it obtains a handle to the signal's slot list and combiner. Next it releases the signal's mutex, before invoking the combiner to iterate through the slot list.
This means that `UnregisterValidationInterface` doesn't prevent more calls to that interface. The fix consists in capturing the `shared_ptr<CValidationInterface>` in each internal slot.
The GUI bug is fixed by using a `Qt::QueuedConnection` in the `WalletModel::unload` connection.

0933a37078 gui: Avoid Wallet::GetBalance in WalletModel::pollBalanceChanged (João Barbosa)
Pull request description:
Each 250ms the slot `WalletModel::pollBalanceChanged` is called which, at worst case, calls `Wallet::GetBalance`. This is a waste of resources since most of the time there aren't new transactions or new blocks. Fix this by early checking if cache is dirty or not.
The actual balance computation can still hang the GUI thread but that is tracked in #16874 and should be fixed with a solution similar to #17135.

e980214bc4 serialization: prevent int overflow for big Coin::nHeight (pierrenn)
Pull request description:
This is an attempt to fix fuzzer issues 1,2,8 reported by practicalswift here : https://github.com/bitcoin/bitcoin/issues/18046
The fuzzer harness doesn't prevent deserialization of unrealistic high values for `Coin::nHeight`. In the [provided examples](https://github.com/bitcoin/bitcoin/issues/18046), we have :
- `blockundo_deserialize` : the varint `0x8DD88DD700` is deserialized as `3944983552` in `Coin::nHeight` (`TxInOutFormatter::Unser`)
- `coins_deserialize` : the varint `0x8DD5D5EC40` is deserialized as `3939874496` similarly
- `txundo_deserialize`: the varint `0x8DCD828F01` is deserialized as `3921725441` in `Coin::nHeight` (`Coin::Unserialize`)
Since `Coin::nHeight` is 31 bit long, multiplying a large value by 2 triggers the fuzzer.
AFAIK those values are unrealistic (~70k years for the smallest..). I've looked a bit a reducing the range of values the fuzzer can deserialize, but this seems to be too much code change for not much.
Hence this PR chooses to static cast `nHeight` when re-serializing; it seems to be the less intrusive/safest way to prevent the fuzzer output.
Another more "upstream" approach would be to limit `Coin::nHeight` values to something more realistic, e.g. `0xFFFFFFF` (~5k years) :
de3a30bab2/src/undo.h (L39) and de3a30bab2/src/coins.h (L71)
Thanks !
