Merge #15870: wallet: Only fail rescan when blocks have actually been pruned
fa7e311e16 [doc] rpcwallet: Only fail rescan when blocks have been pruned (MarcoFalke)

faf3729242 wallet: Only fail rescan when blocks have actually been pruned (MarcoFalke)

Pull request description:

  This brings the behaviour of the import* calls closer to importmulti. After this change, the difference between importmulti and the other import* calls is

  * that in importmulti you can "opt-out" of scanning early blocks by setting a later timestamp.
  * that in importmulti the wallet will successfully import the data, but fail to rescan. Whereas in the other calls, the wallet will abort before importing the data.

After branching off for a major version release of Bitcoin Core, use this template to create the initial release notes draft.

The release notes draft is a temporary file that can be added to by anyone. See /doc/developer-notes.md#release-notes for the process.

Create the draft, named "version Release Notes Draft" (e.g. "0.20.0 Release Notes Draft"), as a collaborative wiki in:

https://github.com/bitcoin-core/bitcoin-devwiki/wiki/

Before the final release, move the notes back to this git repository.

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).

Upgrading directly from a version of Bitcoin Core that has reached its EOL is possible, but might take some time if the datadir needs to be migrated. Old wallet versions of Bitcoin Core are generally supported.

Downgrading warning

The chainstate database for this release is not compatible with previous releases, so if you run 0.15 and then decide to switch back to any older version, you will need to run the old release with the -reindex-chainstate option to rebuild the chainstate data structures in the old format.

If your node has pruning enabled, this will entail re-downloading and processing the entire blockchain.

Compatibility

Bitcoin Core is supported and extensively tested on operating systems using the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended to use Bitcoin Core on unsupported systems.

Bitcoin Core should also work on most other Unix-like systems but is not frequently tested on them.

From 0.17.0 onwards, macOS <10.10 is no longer supported. 0.17.0 is built using Qt 5.9.x, which doesn't support versions of macOS older than 10.10. Additionally, Bitcoin Core does not yet change appearance when macOS "dark mode" is activated.

In addition to previously-supported CPU platforms, this release's pre-compiled distribution also provides binaries for the RISC-V platform.

Notable changes

New RPCs

  • getbalances returns an object with all balances (mine, untrusted_pending and immature). Please refer to the RPC help of getbalances for details. The new RPC is intended to replace getunconfirmedbalance and the balance fields in getwalletinfo, as well as getbalance. The old calls may be removed in a future version.

Updated RPCs

Note: some low-level RPC changes mainly useful for testing are described in the Low-level Changes section below.

  • The sendmany RPC had an argument minconf that was not well specified and would lead to RPC errors even when the wallet's coin selection would succeed. The sendtoaddress RPC never had this check, so to normalize the behavior, minconf is now ignored in sendmany. If the coin selection does not succeed due to missing coins, it will still throw an RPC error. Be reminded that coin selection is influenced by the -spendzeroconfchange, -limitancestorcount, -limitdescendantcount and -walletrejectlongchains command line arguments.

Low-level changes

Configuration

  • An error is issued where previously a warning was issued when a setting in the config file was specified in the default section, but not overridden for the selected network. This change takes only effect if the selected network is not mainnet.

Wallet

  • When in pruned mode, a rescan that was triggered by an importwallet, importpubkey, importaddress, or importprivkey RPC will only fail when blocks have been pruned. Previously it would fail when -prune has been set. This change allows to set -prune to a high value (e.g. the disk size) and the calls to any of the import RPCs would fail when the first block is pruned.
