Merge #13918: rpc: Replace median fee rate with feerate percentiles in getblockstats
4b7091a842 Replace median fee rate with feerate percentiles (Marcin Jachymiak)

Pull request description:

  Currently,  the `medianfeerate` statistic is calculated from the feerate of the middle transaction of a list of transactions sorted by feerate.

  This PR instead uses the value of the 50th percentile weight unit in the block, and also calculates the feerate at the 10th, 25th, 75th, and 90th percentiles.  This more accurately corresponds with what is generally meant by median feerate.

Merge #13666: Always create signatures with Low R values
e306be7429 Use 72 byte dummy signatures when watching only inputs may be used (Andrew Chow)
48b1473c89 Use 71 byte signature for DUMMY_SIGNATURE_CREATOR (Andrew Chow)
18dfea0dd0 Always create 70 byte signatures with low R values (Andrew Chow)

Pull request description:

  When creating signatures for transactions, always make one which has a 32 byte or smaller R and 32 byte or smaller S value. This results in signatures that are always less than 71 bytes (32 byte R + 32 byte S + 6 bytes DER + 1 byte sighash) with low R values. In most cases, the signature will be 71 bytes.

  Because R is not mutable in the same way that S is, a low R value can only be found by trying different nonces. RFC 6979 for deterministic nonce generation has the option to specify additional entropy, so we simply use that and add a uin32_t counter which we increment in order to try different nonces. Nonces are sill deterministically generated as the nonce used will the be the first one where the counter results in a nonce that results in a low R value. Because different nonces need to be tried, time to produce a signature does increase. On average, it takes twice as long to make a signature as two signatures need to be created, on average, to find one with a low R.

  Having a fixed size signature makes size calculations easier and also saves half a byte of transaction size, on average.

  DUMMY_SIGNATURE_CREATOR has been modified to produce 71 byte dummy signatures instead of 72 byte signatures.

fada8966c5 qa: Close stdout and stderr file when node stops (MarcoFalke)

Pull request description:

  ### qa: Close stdout and stderr file when node stops

  Since these files are potentially deleted by the test framework for cleanup, they should be closed first. Otherwise this will lead to errors on Windows when the tests finish successfully.

  Side note: After the patch, it is no longer possible to reopen the file on Windows (see https://docs.python.org/3/library/tempfile.html#tempfile.NamedTemporaryFile)

  ### qa: Run gen_rpcauth with sys.executable

  Similar to `test_runner.py`, the `sys.executable` needs to be passed down into subprocesses to pass on native Windows. (Should have no effect on Linux)

  ###   qa: Use files for stdout/stderr to support Windows

  It seems that using PIPE is not supported on Windows. Also, it is easier to just use the files that capture the stdout and stderr within the test node class.

Merge #13924: tests: Simplify comparison in rpc_blockchain.py
1f87c372b5 Simplify comparison in rpc_blockchain.py. (Daniel Kraft)

Pull request description:

  The test for `gettxoutsetinfo` in `rpc_blockchain.py` verifies that the result is the same as before after invalidating and reconsidering a block.  The comparison has to exclude the `disk_size` field, though, as it is not deterministic.

  Instead of comparing all the other fields for equality, this change explicitly removes the `disk_size` field and then compares the full objects.  This makes the intent more explicit (compare everything except for `disk_size`, not compare just a given list of fields) and also the code simpler.

18dfea0dd0 Always create 70 byte signatures with low R values
When extra entropy is not specified by the caller, CKey::Sign will
now always create a signature that has a low R value and is at most
70 bytes. The resulting signature on the stack will be 71 bytes when
the sighash byte is included.

Using low R signatures means that the resulting DER encoded signature
will never need to have additional padding to account for high R
values.

  This PR aims to clean this up into [three different cases implemented in blocktools.py](https://github.com/conscott/bitcoin/blob/create_tx_cleanup/test/functional/test_framework/blocktools.py#L121-L149)
  1. `create_tx_with_script`: Return transaction object spending generic tx output optionally specifying scriptSig and scriptPubKey
  2. `create_transaction`: Return transaction object spending coinbase tx
  2. `create_raw_transaction`: Return raw transaction (hex string) spending coinbase tx

  I am not committed to any of these function names, so I'll gladly take suggestions on there.

  Additionally there are some related cleanups to feature_block.py tests, specifically removing the [PreviousSpendableOutput](https://github.com/conscott/bitcoin/blob/master/test/functional/feature_block.py#L51-L54) object, which seems like an unnecessary layer given that every instance spends the 0 output.

Merge #13667: wallet: Fix backupwallet for multiwallets
a1a998cf24 wallet: Fix backupwallet for multiwallets (Daniel Kraft)

Pull request description:

  `backupwallet` was broken for multiwallets in their own directories (i.e. something like `DATADIR/wallets/mywallet/wallet.dat`).  In this case, the backup would use `DATADIR/wallets/wallet.dat` as source file and not take the specific wallet's directory into account.

  This led to either an error during the backup (if the wrong source file was not present) or would silently back up the wrong wallet; especially the latter behaviour can be quite bad for users.

Merge #13656: Remove the boost/algorithm/string/predicate.hpp dependency
e3245f2e7b Removes Boost predicate.hpp dependency (251)

Pull request description:

  This pull request removes the `boost/algorithm/string/predicate.hpp` dependency from the project.

  To replace the the `predicate.hpp` dependency from the project the function calls to `boost::algorithm::starts_with` and `boost::algorithm::ends_with` have been replaced with respectively C++11's `std::basic_string::front` and `std::basic_string::back` function calls.

  Refactors that were not required, but have been done anyways:

  - The Boost function `all` was implicitly made available via the `predicate.hpp` header. Instead of including the appropriate header, function calls to `all` have been replaced with function calls to `std::all_of`.

  - The  `boost::algorithm::is_digit` predicate has been replaced with a custom `IsDigit` function that is locale independent and ASCII deterministic.

Pull request description:

  This PR adds an optional (off by default) `-avoidpartialspends` flag, which changes coin select to use output groups rather than outputs, where each output group corresponds to all outputs with the same destination.

  It is a privacy improvement, as each time you spend some output, any other output that is publicly associated with the destination (address) will also be spent at the same time, at the cost of fee increase for cases where coin select without group restriction would find a more optimal set of coins (see example below).

  For regular use without address reuse, this PR should have no effect on the user experience whatsoever; it only affects users who, for some reason, have multiple outputs with the same destination (i.e. address reuse).

  Nodes with this turned off will still try to avoid partial spending, if the fee of the resulting transaction is not greater than the fee of the original transaction.

  Example: a node has four outputs linked to two addresses `A` and `B`:

  * 1.0 btc to `A`
  * 0.5 btc to `A`
  * 1.0 btc to `B`
  * 0.5 btc to `B`

  The node sends 0.2 btc to `C`. Without `-avoidpartialspends`, the following coin selection will occur:
  * 0.5 btc to `A` or `B` is picked
  * 0.2 btc is output to `C`
  * 0.3 - fee is output to (unique change address)

  With `-avoidpartialspends`, the following will instead happen:
  * Both of (0.5, 1.0) btc to `A` or `B` is picked (one or the other pair)
  * 0.2 btc is output to `C`
  * 1.3 - fee is output to (unique change address)

  As noted, the pro here is that, assuming nobody sends to the address after you spend from it, you will only ever use one address once. The con is that the transaction becomes slightly larger in this case, because it is overpicking outputs to adhere to the no partial spending rule.

  This complements #10386, in particular it addresses @luke-jr and @gmaxwell's concerns in https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-300667926 and https://github.com/bitcoin/bitcoin/pull/10386#issuecomment-302361381.

  Together with `-avoidreuse`, this fully addresses the concerns in #10065 I believe.

64b9f27e0e Skip is_closing() check when not available.
https://github.com/bitcoin/bitcoin/pull/13715 introduced a new check
for _transport.is_closing() in mininode's P2PConnection's.  This function
is only available from Python 3.4.4, though, while Bitcoin is supposed
to support all Python 3.4 versions.

In this change, we make the check conditional on is_closing() being
available.  If it is not, then we revert to the behaviour before the
check was introduced; this means that
https://github.com/bitcoin/bitcoin/issues/13579 is not fixed for old
systems, but at least the tests work as they used to do before.

This includes a small refactoring from a one-line lambda to an
inline function, because this makes the code easier to read with more
and more conditions being added.

Fixes https://github.com/bitcoin/bitcoin/issues/13745.

Pull request description:

  This mode ('createwallet {"disableprivatekeys": true}') is intended for a sane pure watch-only mode, ideal for a use-case where one likes to use Bitcoin-Core in conjunction with a hardware-wallet or another solutions for cold-storage.

  Since we have support for custom change addresses in `fundrawtransaction`, pure watch-only wallets including coin-selection are possible and do make sense for some use cases.

  This new mode disables all forms of private key generation and ensure that no mix between hot and cold keys are possible.

41c607f09b Implement PSBT Structures and un/serialization methods per BIP 174 (Andrew Chow)

Pull request description:

  This Pull Request fully implements the [updated](https://github.com/bitcoin/bips/pull/694) BIP 174 specification. It is based upon #13425 which implements the majority of the signing logic.

  BIP 174 specifies a binary transaction format which contains the information necessary for a signer to produce signatures for the transaction and holds the signatures for an input while the input does not have a complete set of signatures.

  This PR contains structs for PSBT, serialization, and deserialzation code. Some changes to `SignatureData` have been made to support detection of UTXO type and storing public keys.

  ***

  Many RPCs have been added to handle PSBTs.

  `walletprocesspsbt` takes a PSBT format transaction, updates the PSBT with any inputs related to this wallet, signs, and finalizes the transaction. There is also an option to not sign and just update.

  `walletcreatefundedpsbt` creates a PSBT from user provided data in the same form as createrawtransaction. It also funds the transaction and takes an options argument in the same form as `fundrawtransaction`. The resulting PSBT is blank with no input or output data filled in. It is analogous to a combination of `createrawtransaction` and `fundrawtransaction`

  `decodepsbt` takes a PSBT and decodes it to JSON. It is analogous to `decoderawtransaction`

  `combinepsbt` takes multiple PSBTs for the same tx and combines them. It is analogous to `combinerawtransaction`

  `finalizepsbt` takes a PSBT and finalizes the inputs. If all inputs are final, it extracts the network serialized transaction and returns that instead of a PSBT unless instructed otherwise.

  `createpsbt` is like `createrawtransaction` but for PSBTs instead of raw transactions.

  `convertpsbt` takes a network serialized transaction and converts it into a psbt. The resulting psbt will lose all signature data and an explicit flag must be set to allow transactions with signature data to be converted.

  ***

  This supersedes #12136

  This takes `<n>` pubkeys and optionally  `<n>` xpubs (together with a definable lookup windows where the default is 0-1000) and looks up common scripts in the UTXO set of all given or derived keys.

  The output will be an array similar to `listunspent`. That array is compatible with `createrawtransaction` as well as with `signrawtransaction`.

  This makes it possible to prepare sweeps and have them signed in a secure (cold) space.

a1a998cf24 wallet: Fix backupwallet for multiwallets
backupwallet was broken for multiwallets in their own directories
(i.e. something like DATADIR/wallets/mywallet/wallet.dat).  In this
case, the backup would use DATADIR/wallets/wallet.dat as source file
and not take the specific wallet's directory into account.

This led to either an error during the backup (if the wrong source
file was not present) or would silently back up the wrong wallet;
especially the latter behaviour can be quite bad for users.

d58055d25f Move AddAndGetDestinationForScript from wallet to outputype module (Anthony Towns)
9a44db2e46 Add outputtype module (Anthony Towns)

Pull request description:

  Adds an "address_type" parameter that accepts "legacy", "p2sh-segwit", and "bech32" to choose the type of address created. Defaults to "legacy" rather than the value of the `-address-type` option for backwards compatibility.

  As part of implementing this, OutputType is moved from wallet into its own module, and `AddAndGetDestinationForScript` is changed to apply to a `CKeyStore` rather than a wallet, and to invoke `keystore.AddCScript(script)` itself rather than expecting the caller to have done that.

  Fixes #12502

Pull request description:

  #12953 inadvertently removed the functionality to call `getbalance "*" <int> <bool>` to get the wallet's balance with either minconfs or include_watchonly.

  This restores that functionality (when `-deprecatedrpc=accounts`), and also makes it possible to call ``getbalance minconf=<int> include_watchonly=<bool>` when accounts are not being used.

685d1d8115 [tests] Check signrawtransaction* errors on missing prevtx info (Anthony Towns)
a3b065b51f Error on missing amount in signrawtransaction* (Anthony Towns)

Pull request description:

  Signatures using segregated witness commit to the amount being spent, so that value must be passed into signrawtransactionwithkey and signrawtransactionwithwallet. This ensures an error is issued if that doesn't happen, rather than just assuming the value is 0 and producing a signature that is almost certainly invalid.

  Based on Ben Woosley's #12458, Fixes: #12429.

Merge #13452: rpc: have verifytxoutproof check the number of txns in proof structure
d280617bf5 [qa] Add a test for merkle proof malleation (Suhas Daftuar)
ed82f17000 have verifytxoutproof check the number of txns in proof structure (Gregory Sanders)

Pull request description:

  Recent publication of a weakness in Bitcoin's merkle tree construction demonstrates many SPV applications vulnerable to an expensive to pull off yet still plausible attack: https://bitslog.wordpress.com/2018/06/09/leaf-node-weakness-in-bitcoin-merkle-tree-design/

  This change would at least allow `verifytxoutproof` to properly validate that the proof matches a known block, with known number of transactions any time after the full block is processed. This should neuter the attack entirely.

  The negative is that a header-only processed block/future syncing mode would cause this to fail until the node has imported the data required.

  related: #13451

  `importprunedfunds` needs this check as well. Can expand it to cover this if people like the idea.

Merge #13603: bitcoin-tx: Stricter check for valid integers
57889e688d bitcoin-tx: Stricter check for valid integers (Daniel Kraft)

Pull request description:

  Just calling `atoi` to convert strings to integers does not check for valid integers very thoroughly; in particular, it just ignores everything starting from the first non-numeral character.  Even a string like "foo" is fine and silently returns 0.

  This meant that `bitcoin-tx` would not fail if such a string was passed in various places where an integer is expected (like the `locktime` or an input/output index); this means that it would, for instance, silently accept a typo and interpret it in an unexpected way.

  In this change, we use `ParseInt64` for parsing strings to integers, which actually verifies that the full string is valid as number.  New tests in the `bitcoin-util-test` cover the new error paths.

  This fixes #13599.

Pull request description:

  `p2p_segwit.py` is a very long test, composed of multiple subtests. When it fails it's difficult to debug for a couple of reasons:

  - Control flow jumps between different methods in the test class, so it's a little difficult to follow the code.
  - state may be carried forward unintentionally from one subtest to the next.

  Improve that by wrapping the subtests with a `@subtest` decorator which:
  - logs progress
  - asserts state after each subtest

  As usual, I've also included a few commits which generally tidy up the test and improve style.
