8cdcaee4c7 [qt] Display more helpful message when adding a send address has failed
Addresses #12796.

When we're unable to add a sending address to the address book because it
already exists as a receiving address, display a message indicating as much.
This should help avoid confusion about an address supposedly already in the
book but which isn't currently visible in the interface.

Merge #12909: wallet: Make fee settings to be non-static members
fac0db0 wallet: Make fee settings non-static members (MarcoFalke)

Pull request description:

  The wallet header defined some globals (they were called "settings"), that should be class members instead.

  This commit is hopefully only refactoring, apart from a multiwallet bugfix: Calling the rpc `settxfee` for one wallet, would set (and change) the fee rate for all loaded wallets. (See added test case)

Pull request description:

  Deprecate all accounts functionality and make it only accessible by using `-deprecatedrpc=accounts`.

  Accounts specific RPCs, account arguments, and account related results all require the `-deprecatedrpc=accunts` startup option now in order to see account things.

  Several wallet functional tests use the accounts system. Those tests are unchanged, except to start the nodes with `-deprecatedrpc=accounts`. We can slowly migrate those tests to use the 'label' API instead of the 'account' API before accounts are fully removed.

Pull request description:

  Default `-printtoconsole` to false for the GUI. GUI programs should not print to the console unnecessarily. For example, when launched by the window manager, the output might end up in the X session log file,
  resulting in duplicate logging. On Windows, it is pointless as well because bitcoin-qt isn't a console application.

  This same mechanism is used to set `-server` to true by default for bitcoind: https://github.com/bitcoin/bitcoin/blob/master/src/bitcoind.cpp#L116

Pull request description:

  This PR moves `FindAndDelete` and `GetOp2` out of CScript (the first is only used inside the interpreter and moved there, the second does not actually depend on any script specifics and works on any vector). Furthermore, all non-const-iterator versions of GetOp are replaced by const ones, removing a number of methods in the process.

  The longer term goal here is making the script interpreter independent from the CScript representation.

  Note for reviewers: both `FindAndDelete` and `GetScriptOp` are consensus critical.

3476e3c [wallet] Fix zapwallettxes/multiwallet interaction. (John Newbery)

Pull request description:

  `-zapwallettxes` should be disallowed when starting bitcoin in multiwallet mode.

  There's code in `WalletInit::ParameterInteraction()` to disallow `-zapwallettxes` when running in multiwallet mode. This code functioned as expected when passing the parameter `-zapwallettxes=1`, but not when passing the parameter `-zapwallettxes` (ie without the value specified). Fix that and add a test.

  The new test in the
  _[wallet] [tests] Test disallowed multiwallet params_ commit reproduces the bug and should fail against master.

  Fixes #12505

Merge #13020: Consistently log CValidationState on call failure
e4d0b44 Consistently log CValidationState on failure (Ben Woosley)

Pull request description:

  This replaces potential silent failures and partial logging with full logging. Seems providing at least minimal visibility to the failure is a good practice. E.g. `FlushStateToDisk` can return a rare but meaningful out of disk space error that would be better to note than leave out.

  Note many of these are related to `ActivateBestChain` or `FlushStateToDisk`. Only a few cases of ignored state remain, e.g. LoadExternalBlockFile and RelayWalletTransaction, where I expect logging would likely be spammy.

  Specifically, this fixes the inability to build

Pull request description:

  As discussed at the IRC meeting back in October (https://botbot.me/freenode/bitcoin-core-dev/2017-10-12/?msg=92231929&page=2), I had looked into the feasibility of enforcing P2SH and SCRIPT_VERIFY_WITNESS back to the genesis block.

  The P2SH change is pretty straightforward -- there was only one historical block on mainnet that violated the rule, so I carved out an exception to it, similar to the way we have exceptions for the BIP30 violators.

  The segwit change is not entirely as clear.  The code changes themselves are relatively straightforward: we can just always turn on SCRIPT_VERIFY_WITNESS whenever P2SH is active.  However conceptually, this amounts to splitting up BIP141 into two parts, the part that implements new script rules, and the part that handles witness commitments in blocks.

  Arguably though the script rules are really defined in BIP 143 anyway, and so this really amounts to backdating BIP 143 -- script rules for v0 segwit outputs -- back to genesis.  So maybe conceptually this isn't so bad...

  I don't feel strongly about this change in either direction; I started working on it because I was searching for a way to simplify the way we understand and implement the consensus rules around segwit, but I'm not yet sure whether I think this achieves anything toward that goal.

Pull request description:

  From now-derelict larger changes I had been working on, here are a series of DRY refactors/cleanups.  Net loss of 35 lines of code - a small step in the good fight.

  In particular I think operator!= should only ever be implemented as a negation of operator==.  Lower chance for errors, and removes the possibility of divergent behavior.

Pull request description:

  Not sure if these should be separate PRs.

  First is removal of a platform abstraction for getting cycle counters where possible.  Since the benchmarking switch to counting number of iterations over a fixed window instead of counting cycles per iteration, these are unused.

  Second is removal of a few methods from the Node interface that seem vestigial from when the concepts of wallet/node were not as clearly separated.

Merge #12982: Fix inconsistent namespace formatting guidelines
cd0e1e91dd Fix inconsistent namespace formatting guidelines (Russell Yanofsky)

Pull request description:

  Suggested formatting for namespaces in the developer guide is currently inconsistent. This commit updates the developer guide and clang-format configuration to consistently put "namespace" and opening/closing braces on the same line. Example:

  ```c++
  namespace boost {
  namespace signals2 {
  class connection;
  } // namespace signals2
  } // namespace boost
  ```

  Currently the [Source code organization](https://github.com/bitcoin/bitcoin/blob/master/doc/developer-notes.md#source-code-organization) section has an example like the one above, but the [Coding style](https://github.com/bitcoin/bitcoin/blob/master/doc/developer-notes.md#coding-style) section example and description put a newline between the opening "namespace foo" and brace (but oddly no newline between closing namespace and brace).

  Avoiding newlines before namespace opening braces makes nested declarations less verbose and also avoids asymmetry with closing braces. It's also a common style used in our own and other codebases:

  The weekly meeting on [2017-12-07](http://www.erisian.com.au/meetbot/bitcoin-core-dev/2017/bitcoin-core-dev.2017-12-07-19.00.log.html) discussed allowing options to bitcoin to have some sensitivity to what network is in use. @theuni suggested having sections in the config file:

      <cfields> an alternative to that would be sections in a config file. and on the
                cmdline they'd look like namespaces. so, [testnet] port=5. or -testnet::port=5.

  This approach is (more or less) supported by `boost::program_options::detail::config_file_iterator` -- when it sees a `[testnet]` section with `port=5`, it will treat that the same as "testnet.port=5". So `[testnet] port=5` (or `testnet.port=5` without the section header) in bitcoin.conf and `-testnet.port=5` on the command line.

  The other aspect to this question is possibly limiting some options so that there is no possibility of accidental cross-contamination across networks. For example, if you're using a particular wallet.dat on mainnet, you may not want to accidentally use the same wallet on testnet and risk reusing keys.

  I've set this up so that the `-addnode` and `-wallet` options are `NETWORK_ONLY`, so that if you have a bitcoin.conf:

      wallet=/secret/wallet.dat
      upnp=1

  and you run `bitcoind -testnet` or `bitcoind -regtest`, then the `wallet=` setting will be ignored, and should behave as if your bitcoin.conf had specified:

      upnp=1

      [main]
      wallet=/secret/wallet.dat

  For any `NETWORK_ONLY` options, if you're using `-testnet` or `-regtest`, you'll have to add the prefix to any command line options. This was necessary for `multiwallet.py` for instance.

  I've left the "default" options as taking precedence over network specific ones, which might be backwards. So if you have:

      maxmempool=200
      [regtest]
      maxmempool=100

  your maxmempool will still be 200 on regtest. The advantage of doing it this way is that if you have `[regtest] maxmempool=100` in bitcoin.conf, and then say `bitcoind -regtest -maxmempool=200`, the same result is probably in line with what you expect...

  The other thing to note is that I'm using the chain names from `chainparamsbase.cpp` / `ChainNameFromCommandLine`, so the sections are `[main]`, `[test]` and `[regtest]`; not `[mainnet]` or `[testnet]` as might be expected.

150b2f0265 Default to defining endian-conversion DECLs in compat w/o config
While this isn't a supported build configuration, some build
systems need to build without going through our autotools steps,
so defaulting to something sane may make it easier to build.

Specifically, this fixes the inability to build
rust-bitcoinconsensus on some non-x86 platforms. It needs to build
without our autotools/configure steps to ensure correct compile
args are passed from the rust build system to gcc. Converting the
args from the rust build system to gcc would be a lot of
unmaintainable work.

  <cfields> ^^ same, but with the LogPrint commented out
  ...
  <wumpus> if both log-to-file and log-to-console is disabled, it should probably bypass all logging
  ```
  Edit: The painful line commented out being the LogPrintf in CWallet::AddToWallet.

45dd135039 Fix csBestBlock/cvBlockChange waiting in rpc/mining (Pieter Wuille)

Pull request description:

  This is an alternative to #11694.

  It reintroduces a uint256 variable with the best block hash, protected by csBestBlock, and only updated while holding it.

  Also rename the involved variable to modern guidelines, as there are very few uses.

Merge #12803: Make BaseSignatureCreator a pure interface
be67831 Make DummySignatureCreator a singleton (Pieter Wuille)
190b8d2 Make BaseSignatureCreator a pure interface (Pieter Wuille)

Pull request description:

  * Removes the `m_provider` field from `BaseSignatureCreator`. Instead both a `SigningProvider` (which provides keys and scripts) and a `BaseSignatureCreator` (which implements the transaction-specific (or other) signing logic) are passed into and down in `ProduceSignature`, making the two concepts orthogonal.
  * Makes `BaseSignatureCreator` a pure interface without constructor, making it easier to implement new derivations of it (for example for message signing).
  * As `DummySignatureCreator` now becomes a stateless object, turn it into a singleton `DUMMY_SIGNATURE_CREATOR`.
