fa7d0503d320900e14c4d9bc016d65c7431070bb rpc: Move OuterType enum to header (MarcoFalke)

Pull request description:

  This enforces most syntax rules of the RPCResult at compile time (or some at run time during unit and functional tests)

  Apart from normalizing the syntax, by separating stylistic formatting from the structure, we could in theory directly generate the html for e.g. https://bitcoincore.org/en/doc/0.19.0/rpc/wallet/importmulti/

869b6314fd180856b6054fff28b5de994252c54c [qt] remove unused parameter from getWarnings() (John Newbery)

Pull request description:

  `GetWarnings()` changes the format of the output warning string based on a passed-in string argument that can be set to "gui" or "statusbar".

  Change the argument to a bool:

  - there are only two types of behaviour, so a bool is a more natural argument type
  - changing the name to `verbose` does not set any expectations for the how the calling code will use the returned string (currently, `statusbar` is used for RPC warnings, not a status bar)
  - removes some error-handling code for when the passed-in string is not one of the two strings expected.

Merge #17728: rpc: require second argument only for scantxoutset start action
7d263571bee8c36fbe3c854b69c6f31cf1ee3b9b rpc: require second argument only for scantxoutset start action (Andrew Chow)

Pull request description:

  It was reported on [IRC](http://www.erisian.com.au/bitcoin-core-dev/log-2019-12-11.html#l-377) that `scantxoutset`'s API was broken in 0.19.0:

  ```
  <belcher> i think scantxoutset may have been broken in bitcoin core 0.19 ? regardless of what parameters i run it with (e.g. "scantxoutset abort", "scantxoutset status") it just returns the help doc, according to the release notes the only change was https://github.com/bitcoin/bitcoin/pull/16285/files but i dont see anything that wouldve broken it, it works fine in 0.18
  <belcher> im on regtest, in case its important
  <harding> I can confirm `scantxoutset abort` returns the help doc on latest master.  Waiting for 0.18.1 to start now to attempt to reproduce there.
  <harding> It looks like it's expecting a second parameter (even though that doesn't make sense with "abort").
  <jonatack> Same for me as well
  <harding> Can also confirm that `scantxoutset abort` returns the expected result on 0.18.1.
  ```

  As noted in the conversation, previously, the second argument of `scanobjects` is only required for the `start` action. `Stop` and `abort` actions did not and could work without them.

  It appears that this was broken by #16240 which enforced the size of the arguments to match the listed required arguments.

  To fix this issue, this PR makes the `scanobjects` argument an optional argument. Then only in the `start` action do we check whether the `scanobjects` argument is there and throw an informative error about that. Also a test is added for this case.

node: Add reference to mempool in NodeContext
Currently it is an alias to the global ::mempool and should be used as
follows.

* Node code (validation and transaction relay) can use either ::mempool
  or node.mempool, whichever seems a better fit.
* RPC code should use the added convenience getter EnsureMempool, which
  makes sure the mempool exists before use. This prepares the RPC code
  to a future where the mempool might be disabled at runtime or compile
  time.
* Test code should use m_node.mempool directly, as the mempool is always
  initialized for tests.

fa5facd3e72b6d61374b0b93b722b55e2b090020 rpc: Remove unused boost::this_thread::interruption_point (MarcoFalke)

Pull request description:

  There are predefined interruption points for `boost::thread`: https://www.boost.org/doc/libs/1_71_0/doc/html/thread/thread_management.html#interruption_points

  However, the rpc threads are `std::thread`, which does not have an `std:🧵:interrupt` member function to request interruption: https://dev.visucore.com/bitcoin/doxygen/httpserver_8cpp.html#ae1a63374e18b9abd348eb74e4243ea34

  Thus, the interruption points can be removed.

Pull request description:

  This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):

  Parent PR: #15606
  Issue: #15605
  Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal

  ---

  This changeset defines the serialization format for UTXO snapshots and adds an RPC command for creating them, `dumptxoutset`. It also adds a convenience script for generating and verifying snapshots at a certain height, since that requires doing a hacky rewind of the chain via `invalidateblock`.

  All of this is unused at the moment.

d6e493f0c2850b522a676a005935163beddaa2cc wallet: Remove left-over BIP70 comment (Fabian Jahr)

Pull request description:

  A small follow-up to #17165 which removed BIP70 support.

  1. Removes one leftover mention of BIP70 in a comment.
  2. Removes BIP70 reference in comments on network/chain name strings. These can be removed as they are not really helpful and also incorrect: BIP70 only defines "main" and "test" but not "regtest". If/When signet gets merged we will add another name to the list that is not defined in BIP70. Mostly there is also an exhaustive list of the options included in the comment anyway.

  If we would like to keep an identifier for this naming scheme, I would suggest switching to something more generic, like 'short chain name'. Happy to implement that if that is preferred. Alternatively, we could add a reference to `CBaseChainParams`. That would also mean we don't have to change these lines again for signet.

Pull request description:

  Carries out some remaining tidy-ups remaining after PR 15141:

  - split ValidationState into TxValidationState and BlockValidationState (commit from ajtowns)
  - various minor code style tidy-ups to the ValidationState class
  - remove the useless `ret` parameter from `ValidationState::Invalid()`
  - remove the now unused `first_invalid` parameter from `ProcessNewBlockHeaders()`
  - remove the `fMissingInputs` parameter from `AcceptToMemoryPool()`, and deal with missing inputs the same way as other errors by using the `TxValidationState` object.

  Tip for reviewers (thanks ryanofsky!): The first commit ("[validation] Add CValidationState subclasses" ) is huge and can be easier to start reviewing if you revert the rote, mechanical changes:

  Substitute the commit hash of commit "[validation] Add CValidationState subclasses" for <CommitHash> in the commands below.

  ```sh
  git checkout <CommitHash>
  git grep -l ValidationState | xargs sed -i 's/BlockValidationState\|TxValidationState/CValidationState/g'
  git grep -l ValidationResult | xargs sed -i 's/BlockValidationResult\|TxValidationResult/ValidationInvalidReason/g'
  git grep -l MaybePunish | xargs sed -i 's/MaybePunishNode\(ForBlock\|ForTx\)/MaybePunishNode/g'
  git diff HEAD^
  ```

  After that it's possible to easily see the mechanical changes with:

  ```sh
  git log -p -n1 -U0 --word-diff-regex=. <CommitHash>
  ```

If this was intentional please ignore this PR.

Note: case might break existing callers

Pull request description:

  The new response keys `height` and `bestblock` allow the client to know at what point the scan took place.

  The help message now has all the response keys (`result` and `txouts` were missing) and it's improved a bit. Note that `searched_items` key is renamed to `txouts`, considering `scantxoutset` is marked experimental.

Merge #16695: rpc: Add window final block height to getchaintxstats
d48c1e837ae1bd08e0f18ad1b57ff72675c3d6ad Add window final block height to getchaintxstats (Jonathan "Duke" Leto)

Pull request description:

  This patch is motivated by the desire to make the output of `getchaintxstats` more useful and optimized for applications to consume and render the data.

  Firstly, this data is already available to the RPC, no additional work is done. Currently additional RPC calls will be needed to look up the height of the final block in the window or the block height that began the window.

  By adding the block height of the final block in the window, the JSON is "self-contained" and applications can calculate the exact block height range of the window with no additional RPC requests.
  For example, a web application which wants to render historical information for `getchaintxstats` RPC on various window sizes might call the RPC with various window lengths, once per day, and store the JSON results somewhere. Because the final block height of each dataset is included, it's no extra work to determine the exact block window range of each JSON response.

Pull request description:

  This hardcodes CSV and segwit activation heights, similar to the BIP 90 buried deployments for BIPs 34, 65 and 66.

  CSV and segwit have been active for over 18 months. Hardcoding the activation height is a code simplification, makes it easier to understand segwit activation status, and reduces technical debt.

  This was originally attempted by jl2012 in #11398 and again by me in #12360.

5693530685 refactor: have CCoins* data managed under CChainState
This change encapsulates UTXO set data within CChainState instances, removing
global data `pcoinsTip` and `pcoinsviewdb`. This is necessary if we want to
maintain multiple chainstates with their own rendering of the UTXO set.

We introduce a class CoinsViews which consolidates the construction of a
CCoins* hierarchy. Construction of its various pieces (db, coinscatcher,
in-memory cache) is split up so that we avoid flushing bad state to disk if
startup is interrupted.

We also introduce `CChainState::CanFlushToDisk()` which tells us when it is
safe to flush the chainstate based on this partial construction.

This commit could be broken into smaller pieces, but it would require more
ephemeral diffs to, e.g., temporarily change CCoinsViewDB's constructor
invocations.

Other changes:

- A parameter has been added to the CCoinsViewDB constructor that allows the
  name of the corresponding leveldb directory to be specified.

Thanks to Russell Yanofsky and Marco Falke for helpful feedback.

Pull request description:

  This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):

  Parent PR: #15606
  Issue: #15605
  Specification: https://github.com/jamesob/assumeutxo-docs/tree/2019-04-proposal/proposal

  ---

  Under an assumeutxo model, we have multiple CChainState instances in use at once in order to support background validation. Currently, each CChainState instance has its own mapBlockIndex, a collection of linked block headers, in addition to a few other data structures that are related to maintenance of the block tree but not necessarily to any given chainstate.

  In order to avoid duplicating this data across chainstates, this change moves chainstate-agnostic block metadata (and related behavior) into a class, `BlockManager`. Chainstates are parameterized with a reference to a blockmanager instance and in practice they share the same instance.

  Most of this change is conceptually move-only, though the diff is somewhat muddled. The first commit can be reviewed slightly more easily with `--color-moved=dimmed_zebra`. Admittedly, that commit is pretty unwieldy; I tried to split it up after the fact with `git add --patch`, but that was difficult because of git's inability to split hunks past a certain point. Some of the moves also ended up being obscured when done over separate commits.

0ab8ba1ac65b70f044a5e323b13d098cef33695a rpc: fix RPC help requirements for getblocktemplate (Karl-Johan Alm)

Pull request description:

  Every single RPC call has a helper-section at the start, which throws a help string if the user asks for help or if the user provided too few/many arguments.

  ```C++
  const RPCHelpMan help{...};
  if (request.fHelp || !help.IsValidNumArgs(request.params.size())) {
      throw std::runtime_error(help.ToString());
  }
  ```

  or (older version)

  ```C++
  if (request.fHelp || request.params.size() < min || request.params.size() > max)
      throw std::runtime_error(
          RPCHelpMan{...}.ToString()
      );
  ```

  It seems like an obvious improvement, and less copy-pasting, to make `RPCHelpMan` aware of `JSONRPCRequest`, and to let it handle the checks instead. Both of the above become

  ```C++
  RPCHelpMan{...}.Check(request);
  ```

  which means we save roughly 3 lines per RPC command, and the `RPCHelpMan` instance is never referenced afterwards, so the approach is a tiny fraction cleaner.

  This is a complete update, sans a few special case locations that had special rules. 623 lines turn into 284 (which includes the addition to `RPCHelpMan`).

Pull request description:

  This adds a descriptors argument to the `utxoupdatepsbt` RPC. This means:
  * Input and output scripts and keys will be filled in 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.

  This also moves some (newly) shared code to separate functions: `UpdatePSBTOutput` (an analogue to `SignPSBTInput`), `IsSegWitOutput`, and `EvalDescriptorStringOrObject` (implementing the string or object notation parsing used in `scantxoutset`).

Pull request description:

  Make reasoning about dependencies easier by not including unused dependencies.

  Please note that the removed headers are _not_ "transitively included" by other still included headers. Thus the removals are real.

  As an added bonus this change means less work for the preprocessor/compiler. At least 51 393 lines of code no longer needs to be processed:

  ```
  $ git diff -u HEAD~1 | grep -E '^\-#include ' | cut -f2 -d"<" | cut -f1 -d">" | \
        sed 's%^%src/%g' | xargs cat | wc -l
  51393
  ```

  Note that 51 393 is the lower bound: the real number is likely much higher when taking into account transitively included headers :-)
