Merge #10976: [MOVEONLY] Move some static functions out of wallet.h/cpp
f01103c MOVEONLY: Init functions wallet/wallet.cpp -> wallet/init.cpp (Russell Yanofsky)
e7fe320 MOVEONLY: Fee functions wallet/wallet.cpp -> wallet/fees.cpp (Russell Yanofsky)
d97fe20 Move some static functions out of wallet.h/cpp (Russell Yanofsky)

Pull request description:

  This just moves some static wallet fee and init functions out of `wallet/wallet.cpp` and into new `wallet/fees.cpp` and `wallet/init.cpp` source files. There is one commit updating declarations and callers, followed by two MOVEONLY commits actually moving the function bodies.

  This change is desirable because wallet.h/cpp are monolithic and hard to navigate, so pulling things out and grouping together pieces of related functionality should improve the organization.

  Another motivation is the wallet process separation work in https://github.com/bitcoin/bitcoin/pull/10973, where (at least initially) parameter parsing and fee estimation are still done in the main process rather than the wallet process, and having functions that run in different processes scrambled up throughout wallet.cpp is unnecessarily confusing.

de9a1db2ed Acquire cs_main lock before cs_wallet during wallet initialization
CWallet::MarkConflicted may acquire the cs_main lock after
CWalletDB::LoadWallet acquires the cs_wallet lock during wallet initialization.
(CWalletDB::LoadWallet calls ReadKeyValue which calls CWallet::LoadToWallet
which calls CWallet::MarkConflicted). This is the opposite order that cs_main
and cs_wallet locks are acquired in the rest of the code, and so leads to
POTENTIAL DEADLOCK DETECTED errors if bitcoin is built with -DDEBUG_LOCKORDER.

This commit changes CWallet::LoadWallet (which calls CWalletDB::LoadWallet) to
acquire both locks in the standard order. It also fixes some tests that were
acquiring wallet and main locks out of order and failed with the new locking in
CWallet::LoadWallet.

Error was reported by Luke Dashjr <luke-jr@utopios.org> in

Merge #11050: Avoid treating null RPC arguments different from missing arguments
745d2e3 Clean up getbalance RPC parameter handling (Russell Yanofsky)
fd5d71e Update developer notes after params.size() cleanup (Russell Yanofsky)
e067673 Avoid treating null RPC arguments different from missing arguments (Russell Yanofsky)
e666efc Get rid of redundant RPC params.size() checks (Russell Yanofsky)

Pull request description:

  This is a followup to #10783.

  - The first commit doesn't change behavior at all, just simplifies code.
  - The second commit just changes RPC methods to treat null arguments the same as missing arguments instead of throwing type errors.
  - The third commit updates developer notes after the cleanup.
  - The forth commit does some additional code cleanup in `getbalance`.

  Followup changes that should happen in future PRs:

  - [ ] Replace uses of `.isTrue()` with calls to `.get_bool()` so numbers, objects, and strings cause type errors instead of being interpreted as false. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133850525
  - [ ] Add braces around if statements. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133851133
  - [ ] Maybe improve UniValue type error exceptions and eliminate RPCTypeCheck and RPCTypeCheckArgument functions. https://github.com/bitcoin/bitcoin/pull/11050#discussion_r133829303

Merge #10952: [wallet] Remove vchDefaultKey and have better first run detection
e53615b Remove vchDefaultKey and have better first run detection (Andrew Chow)

Pull request description:

  Removes vchDefaultKey which was only used for first run detection. Improves wallet first run detection by checking to see if any keys were read from the database.

  This also fixes a (rather contrived) case where an encrypted non-HD wallet has corruption such that the default key is no longer valid and is loaded into a Core version that supports HD wallets. This causes a runtime exception since a new hd master key is generated as the software believes the wallet file is newly created but cannot add the generated key to the wallet since it is encrypted. I was only able to replicate this error by creating a non-hd wallet, encrypting it, then editing the wallet using `db_dump` and `db_load` before loading the wallet with hd enabled. This problem has been reported by [two](https://bitcointalk.org/index.php?topic=1993244.0) [users](https://bitcointalk.org/index.php?topic=1746976.msg17511261#msg17511261) so it is something that can happen, although that raises the question of "what corrupted the default key".

  ~P.S. I don't know what's up with the whitespace changes. I think my text editor is doing something stupid but I don't think those are important enough to attempt undoing them.~ Undid those

Pull request description:

  All calls to `mapWallet.count()` have the intent to detect if a `txid` exists and most are followed by a second lookup to retrieve the `CWalletTx`.

  This PR replaces all `mapWallet.count()` calls with `mapWallet.find()` to avoid the second lookup.

Removes vchDefaultKey which was only used for first run detection.
Improves wallet first run detection by checking to see if any keys
were read from the database.

This will now also check for a valid defaultkey for backwards
compatibility reasons and to check for any corruption.

Keys will stil be generated on the first one, but there won't be
any shown in the address book as was previously done.

e067673f4e Avoid treating null RPC arguments different from missing arguments
This changes RPC methods to treat null arguments the same as missing arguments,
instead of throwing type errors. Specifically:

- `getbalance` method now returns the wallet balance when the `account` param
  is null instead of throwing a type error (same as when parameter is missing).
  It is still an error to supply `minconf` or `watchonly` options when the
  account is null.

- `addnode` and `setban` methods now return help text instead of type errors if
  `command` params are null (same as when params are missing).

- `sendrawtransaction`, `setaccount`, `movecmd`, `sendfrom`,
  `addmultisigaddress`, `listaccounts`, `lockunspent` methods accept null
  default values where missing values were previously allowed, and treat them
  the same.

d97fe2016c Move some static functions out of wallet.h/cpp
This commit just moves a few function declarations and updates callers.
Function bodies are moved in two followup MOVEONLY commits.

This change is desirable because wallet.h/cpp are monolithic and hard to
navigate, so pulling things out and grouping together pieces of related
functionality should improve the organization.

Another proximate motivation is the wallet process separation work in
https://github.com/bitcoin/bitcoin/pull/10973, where (at least initially)
parameter parsing and fee estimation are still done in the main process rather
than the wallet process, and having functions that run in different processes
scrambled up throughout wallet.cpp is unnecessarily confusing.

90d4d89 scripted-diff: Use the C++11 keyword nullptr to denote the pointer literal instead of the macro NULL (practicalswift)

Pull request description:

  Since C++11 the macro `NULL` may be:
  * an integer literal with value zero, or
  * a prvalue of type `std::nullptr_t`

  By using the C++11 keyword `nullptr` we are guaranteed a prvalue of type `std::nullptr_t`.

  For a more thorough discussion, see "A name for the null pointer: nullptr" (Sutter &
  Stroustrup), http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2431.pdf

  With this patch applied there are no `NULL` macro usages left in the repo:

  ```
  $ git grep NULL -- "*.cpp" "*.h" | egrep -v '(/univalue/|/secp256k1/|/leveldb/|_NULL|NULLDUMMY|torcontrol.*NULL|NULL cert)' | wc -l
  0
  ```

  The road towards `nullptr` (C++11) is split into two PRs:
  * `NULL` → `nullptr` is handled in PR #10483 (scripted, this PR)
  * `0` → `nullptr` is handled in PR #10645 (manual)

  - top up the keypool on startup

  Notably, it does not stop the node or prevent the best block from advancing if the keypool drops below a threshold (which means that transactions may be missed and funds lost if restoring from an old HD wallet backup).

876e92b Testing: listsinceblock should display all transactions that were affected since the given block, including transactions that were removed due to a reorg. (Karl-Johan Alm)
f999c46 listsinceblock: optionally find and list any transactions that were undone due to reorg when requesting a non-main chain block in a new 'removed' array. (Karl-Johan Alm)

Pull request description:

  The following scenario will not notify the caller of the fact `tx0` has been dropped:

  1. User 1 receives BTC in tx0 from utxo1 in block aa1.
  2. User 2 receives BTC in tx1 from utxo1 (same) in block bb1
  3. User 1 sees 2 confirmations at block aa3.
  4. Reorg into bb chain.
  5. User 1 asks `listsinceblock aa3` and does not see that tx0 is now invalidated.

  See `listsinceblock.py` commit for related test.

  The proposed fix is to iterate from the given block down to the fork point, and to check each transaction in the blocks against the wallet, in addition to including all transactions from the fork point to the active chain tip (the current behavior). Any transactions that were present will now also be listed in the `listsinceblock` output in a new `replaced` array. This operation may be a bit heavy but the circumstances (and perceived frequency of occurrence) warrant it, I believe.

Merge #10783: [RPC] Various rpc argument fixes
4dc1915 check for null values in rpc args and handle appropriately (Gregory Sanders)
999ef20 importmulti options are optional (Gregory Sanders)
a70d025 fixup some rpc param counting for rpc help (Gregory Sanders)

Pull request description:

  Audited where named args will fail to use correct default values or may fail when additional optional arguments are added.

  Previously for these parameters, it was fine to omit them as positional arguments, but it would trigger UniValue runtime errors to set them to null, or to omit them while passing named parameters with greater positions (which would internally set earlier missing arguments to null). Now null values are treated the same as missing values so these errors do not occur.

  Included a few other small fixes while working on it.

  I didn't bother fixing account-based rpc calls.

Merge #10817: Redefine Dust and add a discard_rate
f4d00e6 Add a discard_rate (Alex Morcos)
b138585 Remove factor of 3 from definition of dust. (Alex Morcos)

Pull request description:

  The definition of dust is redefined to remove the factor of 3.

  Dust is redefined to be the value of an output such that it would
  cost that value in fees to (create and) spend the output at the dust
  relay rate.  The previous definition was that it would cost 1/3 of the
  value.  The default dust relay rate is correspondingly increased to
  3000 sat/kB so the actual default dust output value of 546 satoshis
  for a non-segwit output remains unchanged.  This commit is a refactor
  only unless a dustrelayfee is passed on the commandline in which case
  that number now needs to be increased by a factor of 3 to get the same
  behavior.  -dustrelayfee is a hidden command line option.

  Note: It's not exactly a refactor due to edge case changes in rounding
  as evidenced by the required change to the unit test.

  A discard_rate is added which defaults to 10,000 sat/kB

  Any change output which would be dust at the discard_rate you are
  willing to discard completely and add to fee (as well as continuing to
  pay the fee that would have been needed for creating the change)

  This would be a nice addition for 0.15 and I think will remain useful for 0.16 with the new coin selection algorithms in discussion, but its not crucial.

  It does add translation strings, but we could (should?) avoid that by hiding the option

we use internally, there isnt much benefit in exposing this option,
especially with HD wallets, while there is ample room for users to

This could be particularly nasty in some use-cases (especially
pre-HD-split) - eg a user might fundrawtransaction, then call
getnewaddress, hand out the address for someone to pay them, then
sendrawtransaction. This may result in the user thinking they have
received payment, even though it was really just their own change!

This could obviously result in needless key-reuse.

This fixes an issue where you could reserve a keypool entry, then
top up the keypool, writing out a new key at the given index, then
return they key from the pool. This isnt likely to cause issues,
but given there is no reason to ever re-use keypool indexes
(they're 64 bits...), best to avoid it alltogether.

Merge #10831: Batch flushing operations to the walletdb during top up and increase keypool size.

3a53f19 Pushdown walletdb object through GenerateNewKey/DeriveNewChildKey. (Gregory Maxwell)

Pull request description:

  This carries the walletdb object from top-up through GenerateNewKey/DeriveNewChildKey/CWallet::AddKeyPubKey, which allows us to avoid the flush on destruction until the top up finishes instead of flushing the wallet for every key.

  This speeds up adding keys by well over 10x on my laptop (actually something like 17x), I wouldn't be surprised if it were an even bigger speedup on spinning rust.

  Then it increases the keypool size to 1000. I would have preferred to use 10,000 but in the case where the user creates a new wallet and then turns on encryption it seems kind of dumb to have >400KB of marked-used born unencrypted keys just laying around.

  (Thanks to Matt for cluesticking me on how to bypass the crypter spaghetti)

ecd81df Make CoinControl a required argument to CreateTransaction (Alex Morcos)

Pull request description:

  This builds on #10589  (first 5 commits from that PR, last 5 commits are new)

  The first couple commits refactor to use the CCoinControl class to pass fee calculation parameters around.

  This allows for fixing the buggy interaction in QT between the global payTxFee which can be modified by the RPC call settxfee or temporarily modified by the QT custom fee settings.  Before these changes the GUI could sometimes send a transaction with a recently set payTxFee and not respect the settings displayed in the GUI.   After these changes, using the GUI does not involve the global transaction confirm target or payTxFee.

  The prospective fee displays in the smart fee slider and the coin control dialog are changed to use the fee calculation from GetMinimumFee, this simplifies the code and makes them slightly more correct in edge cases.

  Maxing the fee calculation with the mempool min fee is move from estimateSmartFee to GetMinimumFee.

  This fixes a long standing bug, and should be tagged for 0.15 as it is holding up finalizing the estimatesmartfee RPC API before release.

ff7365e [tests] fix flake8 warnings in zapwallettxes.py (John Newbery)

Pull request description:

  zapwallettxes previously did not interact well with persistent mempool.
  zapwallettxes would cause wallet transactions to be zapped, but they
  would then be reloaded from the mempool on startup. This commit softsets
  persistmempool to false if zapwallettxes is enabled so transactions are
  actually zapped.

  This PR also fixes the zapwallettxes.py functional test, which did not properly test this feature. The test line:

  ```py
       assert_raises(JSONRPCException, self.nodes[0].gettransaction, [txid3])
       #there must be a expection because the unconfirmed wallettx0 must be gone by now
  ```
  is not actually testing the presence of the transaction since the RPC is being called incorrectly (with an array instead of a string). The `assert_raises()` passes since an assert is raised, but it's not the one the test writer had in mind!

  Fixes #9710 .
