Merge #11250: Bump wallet version to 159900 and remove the usehd option
713a92073 Remove usehd option and warn when it is used (Andrew Chow)
d4c18f733 Bump wallet version number to 159900 (Andrew Chow)

Pull request description:

  Bump the wallet version number to 159900 so that new wallets made without a default key will no longer work on previous versions at all. Also remove the `usehd` option to avoid weird interaction with wallet version numbers and HD-ness of wallets.

Merge #11126: Acquire cs_main lock before cs_wallet during wallet initialization
de9a1db Acquire cs_main lock before cs_wallet during wallet initialization (Russell Yanofsky)

Pull request description:

  `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.

Merge #11145: Fix rounding bug in calculation of minimum change
6af49dd Output a bit more information for fee calculation report. (Alex Morcos)
a54c7b9 Fix rounding errors in calculation of minimum change size (Alex Morcos)

Pull request description:

  Thanks to @juscamarena for reporting this.

  Please backport to 0.15.

  There was a potential rounding error where the fee for the change added to the fee for the original tx could be less than the fee for the tx including change.

  This is fixed in the first commit.  The second commit adds one more snippet of information in the fee calculation report.  I actually realized that there is more information that would be nice to report, but we can add that post 0.15.

  An open question is whether we should be returning failure if the test in line 2885 is hit or just resetting pick_new_inputs and continuing.  Originally I made it a failure to avoid any possible infinite loops.  But the case hit here is an example of where that logic possibly backfired.

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.

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

Merge #11039: Avoid second mapWallet lookup
8f2f1e0 wallet: Avoid second mapWallet lookup (João Barbosa)

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.

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)

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

cf82a9e704 Do not allow users to get keys from keypool without reserving them
fundrawtransaction allows users to add a change output and then
not have it removed from keypool. While it would be nice to have
users follow the normal CreateTransaction/CommitTransaction process
we use internally, there isnt much benefit in exposing this option,
especially with HD wallets, while there is ample room for users to
misunderstand or misuse this option.

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.

1fc8c3de0c No longer ever reuse keypool indexes
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.

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)

This prevents the wallet from being flushed between each and

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.

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 .

fd29d3df29 Remove checking of mempool min fee from estimateSmartFee.
This check has been moved to the wallet logic GetMinimumFee. The rpc call to
estimatesmartfee will now no longer return a result maxed with the mempool min
fee, but automated fee calculations from the wallet will produce the same result
as before and coincontrol and sendcoins dialogs in the GUI will correctly
display the right prospective fee.

0f402b9263 Fix rare edge case of paying too many fees when transaction has no change.
Due to the iterative process of selecting new coins in each loop a new fee is
calculated that needs to be met each time.  In the typical case if the most
recent iteration of the loop produced a much smaller transaction and we have now
gathered inputs with too many fees, we can just reduce the change.  However in
the case where there is no change output, it is possible to end up with a
transaction which drastically overpays fees.  This commit addresses that case,
by creating a change output if the overpayment is large enough to support it,
this is accomplished by rerunning the transaction creation loop without
selecting new coins.

Thanks to instagibbs for working on this as well
