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.

Merge #13747: tests: Skip P2PConnection's is_closing() check when not available
64b9f27e0e Skip is_closing() check when not available. (Daniel Kraft)

Pull request description:

  #13715 introduced a new check for `_transport.is_closing()` in mininode's `P2PConnection`'s.  This function is [only available from Python 3.4.4](https://docs.python.org/3.4/library/asyncio-protocol.html#asyncio.BaseTransport.is_closing), though, while Bitcoin Core 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 #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 #13745.

e3245f2e7b Removes Boost predicate.hpp dependency
This is a squashed commit that squashes the following commits:

This commit removes the `boost/algorithm/string/predicate.hpp` dependenc
from the project by replacing the function calls to `boost::algorithm::starts_with`
`boost::algorithm::ends_with` and `all` with respectively C++11'
`std::basic_string::front`, `std::basic_string::back`, `std::all_of` function calls

This commit replaces `boost::algorithm::is_digit` with  a locale independent isdigi
function, because the use of the standard library's `isdigit` and `std::isdigit
functions is discoraged in the developer notes

Merge #13212: Net: Fixed a race condition when disabling the network.
793290f940 Net: Fixed a race condition when disabling the network. (lmanners)

Pull request description:

  This change addresses a race condition where setnetworkactive=false wouldn't always disconnect all peers.

  Before this change, the following could happen:
  1. Thread A -- Begins connecting to a node.
  2. Thread B -- Sets kNetworkActive=false and disconnects connected nodes.
  3. Thread A -- Finishes connecting and adds node to list of connected nodes.

  The node that was connected from Thread A remains connected and active,
  even though kNetworkActive=false.

  To fix the race, disconnections when kNetworkActive=false are now handled in the main network loop.

  fixes #13038

Merge #12764: doc: Remove field in getblocktemplate help that has never been used.
ac8a1d092e [RPC] Remove field in getblocktemplate help that has never been used (Conor Scott)

Pull request description:

  [BIP 22 - getblocktemplate](https://github.com/bitcoin/bips/blob/master/bip-0022.mediawiki#Transactions%20Object%20Format) specifies an optional flag, `required` if the transaction must be in the block.

  Luke's implementation #936 did not include this flag, and it was later added to the help description in #3246 (more than a year later) but the field was still never actually implemented. As far as I can tell, bitcoin core would have never actually included this in a `getblocktemplate` call, so it seems logical to remove it from the help description.

  If I am missing something or this is considered harmless - I can close the PR.

9544a3f3fc tiny refactor for ArgsManager
This commit contains 2 refactors.

1. mark "const" on ArgsManager::GetHelpMessage and IsArgKnown.
2. remove unused "error" argument from ArgsManager::IsArgKnown.

Firstly, I mark "const" on where it is possible to. It is mentioned
before (e.g. https://github.com/bitcoin/bitcoin/pull/13190#pullrequestreview-118823133).

And about 2nd change, ArgsManager::IsArgKnown was added at commit #4f8704d which was
merged at PR #13112. But from its beggining, "error" argument never be used.
I think it should be refactored.

Avoid unnecessarily setting env variables on the lint build
The relevent env variables are set for the matrix builds, and are irrelevant
to the lint build. By default the first matrix entry is applied.

"Each job included in jobs.include inherits the first value of the array that defines a matrix dimension."

Merge #13695: lint: Add linter for circular dependencies
5c613aadd6 lint: Add linter for circular dependencies (Ben Woosley)

Pull request description:

  Protects against added circular depencies, makes it explicit in the
  code when circular dependencies have been removed.

  Modeled after EXPECTED_BOOST_INCLUDES in lint-includes.sh

  Example output:
  ```
  $ test/lint/lint-circular-dependencies.sh
  A new circular dependency in the form of "qt/paymentserver -> qt/walletmodel -> qt/paymentserver" appears to have been introduced.

  $ echo $?
  1
  $ test/lint/lint-circular-dependencies.sh
  Good job! The circular dependency "Fake" is no longer present.
  Please remove it from EXPECTED_CIRCULAR_DEPENDENCIES in test/lint/lint-circular-dependencies.sh
  to make sure this circular dependency is not accidentally reintroduced.

  $ echo $?
  1
  $ test/lint/lint-circular-dependencies.sh
  $ echo $?
  0

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.

Merge #13712: wallet: Fix non-determinism in ParseHDKeypath(...). Avoid using an uninitialized variable in path calculation.

7223263899 wallet: Add tests for ParseHDKeypath(...) (practicalswift)

Pull request description:

  Add error handling. Check return value of `ParseUInt32(...)` in `ParseHDKeypath(...)`.

  `ParseUInt32(...)` returns `false` if the entire string could not be parsed or when an overflow or underflow occurred. In such case the uninitialized variable `number` would be used in the calculation of `path` (prior to this commit).

  An example key path triggering this is `m/0/4294967296`:

  ```
    ParseHDKeypath("m/0/4294967296", keypath);
  ```

  `4294967296` is `1` + `0xFFFFFFFF` (`uint32_t` max: `4294967295`).

  Introduced in a4b06fb42e which was merged into `master` 14 hours ago as part of #13557 ("BIP 174 PSBT Serializations and RPCs").
