78304941f7 Blockchain/RPC: Add scantxoutset method to scan UTXO set (Jonas Schnelli)
9048575511 Add FindScriptPubKey() to search the UTXO set (Jonas Schnelli)

Pull request description:

  Alternative to #9152.

  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.

Merge #13259: refactoring: add a method for determining if a block is pruned or not
e9a1881b90 refactor: add a function for determining if a block is pruned or not (Karl-Johan Alm)

Pull request description:

  The check for whether a block is pruned or not is sufficiently obscure that it deserves a macro. It is also used in 2 places, ~~with more coming, e.g. #10757~~ (turns out it was a move, not an addition).

Pull request description:

  It returns per block statistics about several things. It should be easy to add more if people think of other things to add or remove some if I went too far (but once written, why not keep it? EDIT: answer: not to test or maintain them).

  The currently available options are: minfee,maxfee,totalfee,minfeerate,maxfeerate,avgfee,avgfeerate,txs,ins,outs (EDIT: see updated list in the rpc call documentation)

  For the x axis, one can use height or block.nTime (I guess I could add mediantime if there's interest [EDIT: nobody showed interest but I implemented mediantime nonetheless, in fact there's no distinction between x or y axis anymore, that's for the caller to judge]).

  To calculate fees, -txindex is required.

Merge #10742: scripted-diff: Use scoped enumerations (C++11, "enum class")
1f45e21 scripted-diff: Convert 11 enums into scoped enums (C++11) (practicalswift)

Pull request description:

  Rationale (from Bjarne Stroustrup's ["C++11 FAQ"](http://www.stroustrup.com/C++11FAQ.html#enum)):

  >
  > The enum classes ("new enums", "strong enums") address three problems with traditional C++ enumerations:
  >
  > * conventional enums implicitly convert to int, causing errors when someone does not want an enumeration to act as an integer.
  > * conventional enums export their enumerators to the surrounding scope, causing name clashes.
  > * the underlying type of an enum cannot be specified, causing confusion, compatibility problems, and makes forward declaration impossible.
  >
  > The new enums are "enum class" because they combine aspects of traditional enumerations (names values) with aspects of classes (scoped members and absence of conversions).

499d95e278 Add static_assert to prevent VARINT(<signed value>)
Using VARINT with signed types is dangerous because negative values will appear
to serialize correctly, but then deserialize as positive values mod 128.

This commit changes the VARINT macro to trigger an error by default if called
with an signed value, and updates broken uses of VARINT to pass a special flag
that lets them keep working with no change in behavior.

Merge #12479: RPC: Add child transactions to getrawmempool verbose output
1dfb4e7d7 [Tests] Check output of parent/child tx list from getrawmempool, getmempooldescendants, getmempoolancestors, and REST interface (Conor Scott)
fc44cb108 [RPC] Add list of child transactions to verbose output of getrawmempool (Conor Scott)

Pull request description:

  `bitcoin-cli getrawmempool true` only lists a transaction's parents in the `depends` field. This change adds a `spentby` field to the json response, which lists the transaction's children in the mempool.

  Currently the only way to find child transactions is to use `getrawmempool` or make another call to `getmempooldescendants` and search the response for transactions that list the parent_txid in the `depends` list, which is inefficient.

  This change allows direct lookup of children.

Merge #11748: [Tests] Adding unit tests for GetDifficulty in blockchain.cpp.
3e1ee31 [Tests] Adding unit tests for GetDifficulty in blockchain.cpp. (sean)

Pull request description:

  blockchain.cpp has low unit test coverage. This commit is intended
  to start improving its code coverage to reasonable levels. One or more
  follow up commits will complete the task that this commit is starting
  (though the usefulness of this commit is not dependent upon later
  commits).

  Note that these tests were not written based upon a specification of how
  GetDifficulty *should* work, but rather how it actually *does* work. As
  a result, if there are any bugs in the current GetDifficulty
  implementation, these unit tests serve to lock them in rather than
  expose them.

  -- Why has blockchain.cpp been modified if this is a unit testing change?

  Since the existing GetDifficulty function relies on a global variable,
  chainActive, it was not suitable for unit testing purposes. Both the
  existing GetDifficulty function and the unit tests now call through to
  a new, more modular version of GetDifficulty that can work on any chain,
  not just chainActive.

  -- Why does blockchain_tests.cpp directly include blockchain.cpp instead
  of blockchain.h?

  While the new GetDifficulty function's signature is arguably better than
  the old one's, it still isn't great, and doesn't seem to warrant inclusion
  as part of the blockchain.h API, especially since only test code is
  directly using it. If a better way of exposing the new GetDifficulty
  function to unit tests exists, please mention it and the commit will be
  updated accordingly.

  -- Why is the test fixture named blockchain_difficulty_tests rather than
  blockchain_tests?

  The Bitcoin Core policy for naming unit test files is to match the the
  file under test ("blockchain" becomes "blockchain_tests"). While this
  commit complies with that, blockchain.cpp is a massive file, such that
  having all of the unit tests in one file will tend towards disorder.

Merge #10874: [RPC] getblockchaininfo: Loop through the bip9 soft fork deployments instead of hard coding
e4d0af4 Loop through the bip9 soft fork deployments instead of hard coding (Andrew Chow)

Pull request description:

  Instead of hard coding which deployment statistics should be listed in the `getblockchaininfo` output, loop through the available deployments (except testdummy) when displaying their deployment info.

3e1ee31043 [Tests] Adding unit tests for GetDifficulty in blockchain.cpp.
blockchain.cpp has low unit test coverage. This commit is intended
to start improving its code coverage to reasonable levels. One or more
follow up commits will complete the task that this commit is starting
(though the usefulness of this commit is not dependent upon later
commits).

Note that these tests were not written based upon a specification of how
GetDifficulty *should* work, but rather how it actually *does* work. As
a result, if there are any bugs in the current GetDifficulty
implementation, these unit tests serve to lock them in rather than
expose them.

-- Why has blockchain.cpp been modified if this is a unit testing change?

Since the existing GetDifficulty function relies on a global variable,
chainActive, it was not suitable for unit testing purposes. Both the
existing GetDifficulty function and the unit tests now call through to
a new, more modular version of GetDifficulty that can work on any chain,
not just chainActive.

-- Why does blockchain_tests.cpp directly include blockchain.cpp instead
of blockchain.h?

While the new GetDifficulty function's signature is arguably better than
the old one's, it still isn't great, and doesn't seem to warrant inclusion
as part of the blockchain.h API, especially since only test code is
directly using it. If a better way of exposing the new GetDifficulty
function to unit tests exists, please mention it and the commit will be
updated accordingly.

-- Why is the test fixture named blockchain_difficulty_tests rather than
blockchain_tests?

The Bitcoin Core policy for naming unit test files is to match the the
file under test ("blockchain" becomes "blockchain_tests"). While this
commit complies with that, blockchain.cpp is a massive file, such that
having all of the unit tests in one file will tend towards disorder.
Since there will be a lot more tests added to this file, the intention
is to divide up different types of tests into different test fixtures
within the same file.

bd9c18171 [rpc] Add initialblockdownload to getblockchaininfo (John Newbery)

Pull request description:

  Exposing whether the node is in IBD would help for testing, and may be useful in general, particularly for developers.

  First discussed in #10357 here: https://github.com/bitcoin/bitcoin/pull/10357#pullrequestreview-59963870

  > ... we could simplify this (and possibly other) tests by just adding a way to know if a node is in IBD. I'd like to do that, but I'm not sure it makes sense to complicate this PR with discussion over how that information should be made available. Eg it's not clear to me that the notion of being in IBD is worth exposing to the casual user, versus a hidden rpc call or something, since the definition has changed over time, and may continue to change in the future. But I still do agree that at least for testing purposes it would be far simpler to expose the field somehow...

   This PR currently implements the simplest way of doing this: adding an `initialblockdownload` field to `getblockchaininfo`. Other approaches we could take:

  1. add a new debug RPC method that exposes `IBD` and potentially other information.
  2. add a parameter to `getblockchaininfo`, eg `debug_info`, which would cause it to return debug information including IBD
  3. add a query string to the url `?debug=true` which would cause RPCs to return additional debug information.

  I quite like the idea of (3). Feedback on these and other approaches very much welcomed!
