Merge #9662: Add createwallet "disableprivatekeys" option: a sane mode for watchonly-wallets
a3fa4d6a6a QA: Fix bug in -usecli logic that converts booleans to non-lowercase strings (Jonas Schnelli)
4704e5f074 [QA] add createwallet disableprivatekey test (Jonas Schnelli)
c7b8f343e9 [Qt] Disable creating receive addresses when private keys are disabled (Jonas Schnelli)
2f15c2bc20 Add disable privatekeys option to createwallet (Jonas Schnelli)
cebefba085 Add option to disable private keys during internal wallet creation (Jonas Schnelli)
9995a602a6 Add facility to store wallet flags (64 bits) (Jonas Schnelli)

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 #13500: [wallet] Decouple wallet version from client version

Pull request description:

Merge #13072: Update createmultisig RPC to support segwit
f40b3b82df [tests] functional test for createmultisig RPC (Anthony Towns)
b9024fdda3 segwit support for createmultisig RPC (Anthony Towns)
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.

Merge #12944: [wallet] ScanforWalletTransactions should mark input txns as dirty
3c292cc19 ScanforWalletTransactions should mark input txns as dirty (Gregory Sanders)

Pull request description:

  I'm hitting a corner case in my mainnet wallet where I load a restore a wallet, call `rescanblockchain` from RPC, and it's "double counting" an output I've sent to myself since currently it never marks input transactions as dirty. This is fixed by a restart of the wallet.

  Note that this only happens with keys with birthdate *after* the blocks containing the spent funds which gets scanned on startup, so it's hard to test without a set seed function.

beef7ec4be Remove useless mapRequest tracking that just effects Qt display.
I thought we had removed this a long time ago, TBH, its really
confusing feedback to users that we display whether a tx was
broadcast to immediate neighbor nodes, given that has little
indication of whether the tx propagated very far.

e6b9730c4 Do not expose invalidity from IsMine (Pieter Wuille)

Pull request description:

  This improves the handling of INVALID in IsMine:
  * Extra INVALID conditions were added to `IsMine` (following https://github.com/bitcoin/bitcoin/pull/13142/files#r185349057), but these were untested. Add unit tests for them.
  * In https://github.com/bitcoin/bitcoin/pull/13142#issuecomment-386396975 it was suggested to merge `isInvalid` into the return status. This PR takes a different approach, and removes the `isInvalid` entirely. It was only ever used inside tests, as normal users of IsMine don't care about the reason for non-mine-ness, only whether it is or not. As the unit tests are extensive enough, it seems sufficient to have a black box text (with tests for both compressed and uncompressed keys).

  Some addition code simplification is done as well.

Break circular dependency: init -> * -> init by extracting shutdown.h
Most includers just wanted to react to pending shutdown.

This isolates access to `fRequestShutdown` and limits access to the shutdown
api functions, including the new `AbortShutdown` for setting it to `false`.

Note I originally called `AbortShutdown` `CancelShutdown` but that name was
already taken by winuser.h
https://travis-ci.org/bitcoin/bitcoin/jobs/386913329

This change also triggered a build error in bench. Fixing it required moving LIBBITCOIN_SERVER after LIBBITCOIN_WALLET in bench_bench_bitcoin_LDADD To make
server definitions in src/net.cpp available to wallet methods in
src/wallet/wallet.cpp. Specifically, solving:

  wallet.cpp:(.text+0x3f0e): undefined reference to `CConnman::NodeFullyConnected(CNode const*)'

scripted-diff: Avoid temporary copies when looping over std::map
The ::value_type of the std::map/std::multimap/std::unordered_map containers is
std::pair<const Key, T>. Dropping the const results in an unnecessary copy,
for example in C++11 range-based loops.

For this I started with a more general scripted diff, then narrowed it down
based on the inspection showing that all actual map/multimap/unordered_map
variables used in loops start with m or have map in the name.

  (and, often, the enclosing loop).

  In most cases, this input is already immediately available and need not be

Merge #13309: Directly operate with CMutableTransaction in SignSignature

Pull request description:

  Refactored `TransactionSignatureCreator` into a templated `GenericTransactionSignatureCreator` that works with both `CMutableTransaction` and `CTransaction`.

  The advantage is that now in `SignSignature`, the `MutableTransactionSignatureCreator` can now operate directly with the `CMutableTransaction` without the need to copy the data into a `CTransaction`.

  Running all unit tests brings a very noticable speedup on my machine:

      48.4 sec before this change
      36.4 sec with this change
      --------
      12.0 seconds saved

      16.7 sec before this change
       5.9 sec with this change
      --------

  This relates to my first attempt with the const_cast hack #13202, and to the slow unit test issue #10026.

  Also see #13050 which modifies the tests but not the production code (like this PR) to get a speedup.

Merge #13252: Wallet: Refactor ReserveKeyFromKeyPool for safety
4b62bdf513 Wallet: Refactor ReserveKeyFromKeyPool for safety (Ben Woosley)

Pull request description:

  ReserveKeyFromKeyPool's previous behaviour is to set nIndex to -1 if the keypool is
  empty, OR throw an exception for technical failures. Instead, we now return false
  if the keypool is empty, true if the operation succeeded.

  This is to make failure more easily detectable by calling code.

6b8b63af14 Generic TransactionSignatureCreator works with both CTransaction and CMutableTransaction
Templated version so that no copying of CMutableTransaction into a CTransaction is
necessary. This speeds up the test case transaction_tests/test_big_witness_transaction
from 7.9 seconds to 3.1 seconds on my machine.

Merge #13142: Separate IsMine from solvability
c004ffc9b4 Make handling of invalid in IsMine more uniform (Pieter Wuille)
a53f0feff8 Add some checks for invalid recursion in IsMine (Pieter Wuille)
b5802a9f5f Simplify IsMine logic (Pieter Wuille)
4e91820531 Make IsMine stop distinguishing solvable/unsolvable (Pieter Wuille)
6d714c3419 Make coincontrol use IsSolvable to determine solvability (Pieter Wuille)

Pull request description:

  Our current `IsMine` logic does several things with outputs:
  * Determine "spendability" (roughly corresponding to "could we sign for this")
  * Determine "watching" (is this an output directly or indirectly a watched script)
  * Determine invalidity (is this output definitely not legally spendable, detecting accidental uncompressed pubkeys in witnesses)
  * Determine "solvability" (would we be able to sign for this ignoring the fact that we may be missing some private keys).

  The last item (solvability) is mostly unrelated and only rarely needed (there is just one instance, inside the wallet's coin control logic). This PR changes that instance to use the separate `IsSolvable` function, and stop `IsMine` from distinguishing between solvable and unsolvable.

  As an extra, this also simplifies the `IsMine` logic and adds some extra checks (which wouldn't be hit unless someone adds already invalid scripts to their wallet).

Merge #13063: Use shared pointer to retain wallet instance
80b4910f7d wallet: Use shared pointer to retain wallet instance (João Barbosa)

Pull request description:

  Currently there are 3 places where it makes sense to retain a wallet shared pointer:
   - `vpwallets`;
   - `interfaces::Wallet` interface instance - used by the UI;
   - wallet RPC functions - given by `GetWalletForJSONRPCRequest`.

  The way it is now it is possible to have, for instance, listunspent RPC and in parallel unload the wallet (once #13111 is merged) without blocking. Once the RPC finishes, the shared pointer will release the wallet.

  It is also possible to get all existing wallets without blocking because the caller keeps a local list of shared pointers.

  This is mostly relevant for wallet unloading.

  This PR replaces #11402.

Merge #13011: Cache witness hash in CTransaction
fac1223a56 Cache witness hash in CTransaction (MarcoFalke)
faab55fbb1 Make CMutableTransaction constructor explicit (MarcoFalke)

Pull request description:

  This speeds up:
  * compactblocks (v2)
  * ATMP
  * validation and miner (via `BlockWitnessMerkleRoot`)
  * sigcache (see also unrelated #13204)
  * rpc and rest (nice, but irrelevant)

  This presumably slows down rescan, which uses a `CTransaction` and its `GetHash`, but never uses the `GetWitnessHash`. The slow down is proportional to the number of witness transactions in the rescan window. I.e. early in the chain there should be no measurable slow down. Later in the chain, there should be a slow down, but acceptable given the speedups in the modules mentioned above.
