c0859b7dac5f3504d753f5dcd7ee272fdb43bea6 build: 0.19 release updates on master (Jon Atack)

Pull request description:

  Post split-off. As per https://github.com/bitcoin/bitcoin/blob/master/doc/release-process.md#before-every-major-release and  issue #16996.

  Note: after split-off, the same changes should be made on the new 0.19.0 release branch, with also these additional changes to both files (configure.ac and build_msvc/bitcoin_config.h):

    - set `CLIENT_VERSION_REVISION` to `0`
    - set `CLIENT_VERSION_IS_RELEASE` to `true`

  The second commit resets the release notes after branch-off and proposes a few improvements.

platform.
Notable changes Notable changes
=============== ===============
New user documentation
----------------------
- [Reduce memory](https://github.com/bitcoin/bitcoin/blob/master/doc/reduce-memory.md)
suggests configuration tweaks for running Bitcoin Core on systems with
limited memory. (#16339)
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
`getbalance`, `getunconfirmedbalance`, and the balance fields in
`getwalletinfo`. These old calls and fields may be removed in a
future version. (#15930, #16239)
- `setwalletflag` sets and unsets wallet flags that enable or disable
features specific to that existing wallet, such as the new
`avoid_reuse` feature documented elsewhere in these release notes.
(#13756)
- `getblockfilter` gets the BIP158 filter for the specified block. This
RPC is only enabled if block filters have been created using the
`-blockfilterindex` configuration option. (#14121)
New settings
------------
- `-blockfilterindex` enables the creation of BIP158 block filters for
the entire blockchain. Filters will be created in the background and
currently use about 4 GiB of space. Note: this version of Bitcoin
Core does not serve block filters over the P2P network, although the
local user may obtain block filters using the `getblockfilter` RPC.
(#14121)
Updated settings
----------------
- `whitebind` and `whitelist` now accept a list of permissions to
provide peers connecting using the indicated interfaces or IP
addresses. If no permissions are specified with an address or CIDR
network, the implicit default permissions are the same as previous
releases. See the `bitcoind -help` output for these two options for
details about the available permissions. (#16248)
Updated RPCs
------------
Note: some low-level RPC changes mainly useful for testing are described in the
Low-level Changes section below.
- `sendmany` no longer has a `minconf` argument. This argument was not
well specified and would lead to RPC errors even when the wallet's
coin selection succeeded. Users who want to influence coin selection
can use the existing `-spendzeroconfchange`, `-limitancestorcount`,
`-limitdescendantcount` and `-walletrejectlongchains` configuration
arguments. (#15596)
- `getbalance` and `sendtoaddress`, plus the new RPCs `getbalances` and
`createwallet`, now accept an "avoid_reuse" parameter that controls
whether already used addresses should be included in the operation.
Additionally, `sendtoaddress` will avoid partial spends when
`avoid_reuse` is enabled even if this feature is not already enabled
via the `-avoidpartialspends` command line flag because not doing so
would risk using up the "wrong" UTXO for an address reuse case.
(#13756)
- RPCs which have an `include_watchonly` argument or `includeWatching` option now default to `true` for watch-only
wallets. Affected RPCs are: `getbalance`, `listreceivedbyaddress`, `listreceivedbylabel`, `listtransactions`,
`listsinceblock`, `gettransaction`, `walletcreatefundedpsbt`, and `fundrawtransaction`. (#16383)
- `listunspent` now returns a "reused" bool for each output if the
wallet flag "avoid_reuse" is enabled. (#13756)
- `getblockstats` now uses BlockUndo data instead of the transaction
index, making it much faster, no longer dependent on the `-txindex`
configuration option, and functional for all non-pruned blocks.
(#14802)
- `utxoupdatepsbt` now accepts a `descriptors` parameter that will fill
out input and output scripts and keys when known. P2SH-witness inputs
will be filled in from the UTXO set when a descriptor is provided that
shows they're spending segwit outputs. See the RPC help text for full
details. (#15427)
- `sendrawtransaction` and `testmempoolaccept` no longer accept a
`allowhighfees` parameter to fail mempool acceptance if the
transaction fee exceedes the value of the configuration option
`-maxtxfee`. Now there is a hardcoded default maximum feerate that
can be changed when calling either RPC using a `maxfeerate` parameter.
(#15620)
- `getmempoolancestors`, `getmempooldescendants`, `getmempoolentry`, and
`getrawmempool` no longer return a `size` field unless the
configuration option `-deprecatedrpc=size` is used. Instead a new
`vsize` field is returned with the transaction's virtual size
(consistent with other RPCs such as `getrawtransaction`). (#15637)
- `getwalletinfo` now includes a `scanning` field that is either `false`
(no scanning) or an object with information about the duration and
progress of the wallet's scanning historical blocks for transactions
affecting its balances. (#15730)
- `gettransaction` now accepts a third (boolean) argument `verbose`. If
set to `true`, a new `decoded` field will be added to the response containing
the decoded transaction. This field is equivalent to RPC `decoderawtransaction`,
or RPC `getrawtransaction` when `verbose` is passed.
- `createwallet` accepts a new `passphrase` parameter. If set, this
will create the new wallet encrypted with the given passphrase. If
unset (the default) or set to an empty string, no encryption will be
used. (#16394)
- `getchaintxstats` RPC now returns the additional key of
`window_final_block_height`.
- `getmempoolentry` now provides a `weight` field containing the
transaction weight as defined in BIP141. (#16647)
- The `getnetworkinfo` and `getpeerinfo` commands now contain a new field with decoded network service flags.
- `getdescriptorinfo` now returns an additional `checksum` field
containing the checksum for the unmodified descriptor provided by the
user (that is, before the descriptor is normalized for the
`descriptor` field). (#15986)
- `joinpsbts` will shuffle the order of the inputs and outputs of the resulting joined psbt.
Previously inputs and outputs were added in the order that the PSBTs were provided which makes correlating inputs to outputs extremely easy.
- `walletcreatefundedpsbt` now signals BIP125 Replace-by-Fee if the
`-walletrbf` configuration option is set to true. (#15911)
GUI changes
-----------
- Provides bech32 addresses by default. The user may change the address
during invoice generation using a GUI toggle, or the default address
type may be changed by the `-addresstype` configuration option.
(#15711, #16497)
- In 0.18.0 a `./configure` flag was introduced to allow disabling BIP70 support in the GUI (support was enabled by default). In 0.19.0 this flag is now __disabled__ by default.
- If you want compile Bitcoin Core with BIP70 support in the GUI, you can pass `--enable-bip70` to `./configure`.
Deprecated or removed configuration options
-------------------------------------------
- `-mempoolreplacement` is removed, although default node behavior
remains the same. This option previously allowed the user to prevent
the node from accepting or relaying BIP125 transaction replacements.
This is different from the remaining configuration option
`-walletrbf`. (#16171)
Deprecated or removed RPCs
--------------------------
- `bumpfee` no longer accepts a `totalFee` option unless the
configuration parameter `deprecatedrpc=totalFee` is specified. This
parameter will be fully removed in a subsequent release. (#15996)
- `generate` is now removed after being deprecated in Bitcoin Core 0.18.
Use the `generatetoaddress` RPC instead. (#15492)
P2P changes
-----------
- BIP 61 reject messages were deprecated in v0.18. They are now disabled
by default, but can be enabled by setting the `-enablebip61` command
line option. BIP 61 reject messages will be removed entirely in a
future version of Bitcoin Core. (#14054)
- To eliminate well-known denial-of-service vectors in Bitcoin Core,
especially for nodes with spinning disks, the default value for the
`-peerbloomfilters` configuration option has been changed to false.
This prevents Bitcoin Core from sending the BIP111 NODE_BLOOM service
flag, accepting BIP37 bloom filters, or serving merkle blocks or
transactions matching a bloom filter. Users who still want to provide
bloom filter support may either set the configuration option to true
to re-enable both BIP111 and BIP37 support or enable just BIP37
support for specific peers using the updated `-whitelist` and
`-whitebind` configuration options described elsewhere in these
release notes. For the near future, lightweight clients using public
BIP111/BIP37 nodes should still be able to connect to older versions
of Bitcoin Core and nodes that have manually enabled BIP37 support,
but developers of such software should consider migrating to either
using specific BIP37 nodes or an alternative transaction filtering
system. (#16152)
Miscellaneous CLI Changes
-------------------------
- The `testnet` field in `bitcoin-cli -getinfo` has been renamed to
`chain` and now returns the current network name as defined in BIP70
(main, test, regtest). (#15566)
Low-level changes
=================
RPC
---
- `getblockchaininfo` no longer returns a `bip9_softforks` object.
Instead, information has been moved into the `softforks` object and
an additional `type` field describes how Bitcoin Core determines
whether that soft fork is active (e.g. BIP9 or BIP90). See the RPC
help for details. (#16060)
- `getblocktemplate` no longer returns a `rules` array containing `CSV`
and `segwit` (the BIP9 deployments that are currently in active
state). (#16060)
- `getrpcinfo` now returns a `logpath` field with the path to
`debug.log`. (#15483)
Tests
-----
- The regression test chain enabled by the `-regtest` command line flag
now requires transactions to not violate standard policy by default.
This is the same default used for mainnet and makes it easier to test
mainnet behavior on regtest. Note that the testnet still allows
non-standard txs by default and that the policy can be locally
adjusted with the `-acceptnonstdtxn` command line flag for both test
chains. (#15891)
Configuration
------------
- A setting specified in the default section but not also specified in a
network-specific section (e.g. testnet) will now produce an error
preventing startup instead of just a warning unless the network is
mainnet. This prevents settings intended for mainnet from being
applied to testnet or regtest. (#15629)
- On platforms supporting `thread_local`, log lines can be prefixed with
the name of the thread that caused the log. To enable this behavior,
use `-logthreadnames=1`. (#15849)
Network
-------
- When fetching a transaction announced by multiple peers, previous versions of
Bitcoin Core would sequentially attempt to download the transaction from each
announcing peer until the transaction is received, in the order that those
peers' announcements were received. In this release, the download logic has
changed to randomize the fetch order across peers and to prefer sending
download requests to outbound peers over inbound peers. This fixes an issue
where inbound peers could prevent a node from getting a transaction.
(#14897, #15834)
- If a Tor hidden service is being used, Bitcoin Core will be bound to
the standard port 8333 even if a different port is configured for
clearnet connections. This prevents leaking node identity through use
of identical non-default port numbers. (#15651)
Mempool and transaction relay
-----------------------------
- Allows one extra single-ancestor transaction per package. Previously,
if a transaction in the mempool had 25 descendants, or it and all of
its descendants were over 101,000 vbytes, any newly-received
transaction that was also a descendant would be ignored. Now, one
extra descendant will be allowed provided it is an immediate
descendant (child) and the child's size is 10,000 vbytes or less.
This makes it possible for two-party contract protocols such as
Lightning Network to give each participant an output they can spend
immediately for Child-Pays-For-Parent (CPFP) fee bumping without
allowing one malicious participant to fill the entire package and thus
prevent the other participant from spending their output. (#15681)
- Transactions with outputs paying v1 to v16 witness versions (future
segwit versions) are now accepted into the mempool, relayed, and
mined. Attempting to spend those outputs remains forbidden by policy
("non-standard"). When this change has been widely deployed, wallets
and services can accept any valid bech32 Bitcoin address without
concern that transactions paying future segwit versions will become
stuck in an unconfirmed state. (#15846)
- Legacy transactions (transactions with no segwit inputs) must now be
sent using the legacy encoding format, enforcing the rule specified in
BIP144. (#14039)
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 setting `-prune` to a high value
(e.g. the disk size) without the calls to any of the import RPCs
failing until the first block is pruned. (#15870)
- When creating a transaction with a fee above `-maxtxfee` (default 0.1
BTC), the RPC commands `walletcreatefundedpsbt` and
`fundrawtransaction` will now fail instead of rounding down the fee.
Be aware that the `feeRate` argument is specified in BTC per 1,000
vbytes, not satoshi per vbyte. (#16257)
- A new wallet flag `avoid_reuse` has been added (default off). When
enabled, a wallet will distinguish between used and unused addresses,
and default to not use the former in coin selection. When setting
this flag on an existing wallet, rescanning the blockchain is required
to correctly mark previously used destinations. Together with "avoid
partial spends" (added in Bitcoin Core v0.17.0), this can eliminate a
serious privacy issue where a malicious user can track spends by
sending small payments to a previously-paid address that would then
be included with unrelated inputs in future payments. (#13756)
Build system changes
--------------------
- Python >=3.5 is now required by all aspects of the project. This
includes the build systems, test framework and linters. The previously
supported minimum (3.4), was EOL in March 2019. (#14954)
- The minimum supported miniUPnPc API version is set to 10. This keeps
compatibility with Ubuntu 16.04 LTS and Debian 8 `libminiupnpc-dev`
packages. Please note, on Debian this package is still vulnerable to
[CVE-2017-8798](https://security-tracker.debian.org/tracker/CVE-2017-8798)
(in jessie only) and
[CVE-2017-1000494](https://security-tracker.debian.org/tracker/CVE-2017-1000494)
(both in jessie and in stretch). (#15993)
