045eeb8870 Rename account to label where appropriate
This change only updates strings and adds RPC aliases, but should simplify the
implementation of address labels in
https://github.com/bitcoin/bitcoin/pull/7729, by getting renaming out of the
way and letting it focus on semantics.

The difference between accounts and labels is that labels apply only to
addresses, while accounts apply to both addresses and transactions
(transactions have "from" and "to" accounts). The code associating accounts
with transactions is clumsy and unreliable so we would like get rid of it.

6ef99826b9 Actually disable BnB when there are preset inputs
We don't want to use BnB when there are preset inputs because there
is some weirdness with making that work with using the KnapsackSolver
as the fallback. Currently we say that we haven't used bnb when
there are preset inputs, but we don't actually disable BnB. This fixes
that.

Pull request description:

  This is an implementation of the [Branch and Bound coin selection algorithm written by Murch](http://murch.one/wp-content/uploads/2016/11/erhardt2016coinselection.pdf) (@xekyo). I have it set so this algorithm will run first and if it fails, it will fall back to the current coin selection algorithm. The coin selection algorithms and tests have been refactored to separate files instead of having them all in wallet.cpp.

  I have added some tests for the new algorithm and a test for all of coin selection in general. However, more tests may be needed, but I will need help with coming up with more test cases.

  This PR uses some code borrowed from #10360 to use effective values when selecting coins.

Merge #9680: Unify CWalletTx construction
b4bc32a451 [wallet] Get rid of CWalletTx default constructor (Russell Yanofsky)
a128bdc9e1 [wallet] Construct CWalletTx objects in CommitTransaction (Russell Yanofsky)

Pull request description:

  Two commits:

  - `Construct CWalletTx objects in CommitTransaction` moves a bunch of CWalletTx initialization into CWallet::CommitTransaction to dedup some code and avoid future inconsistencies in how wallet transactions are created.
  - `Get rid of CWalletTx default constructor` does what is described and eliminates the possibility of empty transaction entries being inadvertently created by mapWallet[hash] accesses.

  Both of these changes were originally part of #9381

33eb9071b9 Fix ComputeTimeSmart test failure with -DDEBUG_LOCKORDER
Failure looks like:

    Entering test case "ComputeTimeSmart"
    test_bitcoin: sync.cpp💯 void potential_deadlock_detected(const std::pair<void*, void*>&, const LockStack&, const LockStack&): Assertion `false' failed.
    unknown location(0): fatal error in "ComputeTimeSmart": signal: SIGABRT (application abort requested)

Reproducible with:

6a34ff5335 Have SelectCoinsMinConf and SelectCoins use BnB or Knapsack and use it
Allows SelectCoinsMinConf and SelectCoins be able to switch between
using BnB or Knapsack for choosing coins.

Has SelectCoinsMinConf do the preprocessing necessary to support either
BnB or Knapsack. This includes calculating the filtering the effective
values for each input.

Uses BnB in CreateTransaction to find an exact match for the output.
If BnB fails, it will fallback to the Knapsack solver.

b4bc32a451 [wallet] Get rid of CWalletTx default constructor
No change in behavior in the normal case. But buggy mapWallet lookups with
invalid txids will now throw exceptions instead of inserting dummy entries into
the map, and potentially causing segfaults and other failures.

This also makes it a compiler error to use the mapWallet[hash] syntax which
could create dummy entries.

This also makes it possible to avoid confusing and wasteful CWalletTx copies in

Merge #11687: External wallet files
be8ab7d08 Create new wallet databases as directories rather than files (Russell Yanofsky)
26c06f24e Allow wallet files not in -walletdir directory (Russell Yanofsky)
d8a99f65e Allow wallet files in multiple directories (Russell Yanofsky)

Pull request description:

  This change consists of three commits:

  * The first commit is a pure refactoring that removes the restriction that two wallets can only be opened at the same time if they are contained in the same directory.
  * The second commit removes the restriction that `-wallet` filenames can only refer to files in the `-walletdir` directory.
  * The third commit makes second commit a little safer by changing bitcoin to create wallet databases as directories rather than files, so they can be safely backed up.

  All three commits should be straightforward:

  *  The first commit adds around 20 lines of new code and then updates a bunch of function signatures (generally updating them to take plain fs::path parameters, instead of combinations of strings, fs::paths, and objects like CDBEnv and CWalletDBWrapper).
  * The second commit removes two `-wallet` filename checks and adds some test cases to the multiwallet unit test.
  * The third commit just changes the mapping from specified wallet paths to bdb environment & data paths.

  **Note:** For anybody looking at this PR for the first time, I think you can skip the comments before _20 Nov_ and start reading at https://github.com/bitcoin/bitcoin/pull/11687#issuecomment-345625565. Comments before  _20 Nov_ were about an earlier version of the PR that didn't include the third commit, and then confusion from not seeing the first commit.

32e69fa0d Replace CBitcoinSecret with {Encode,Decode}Secret (Pieter Wuille)

Pull request description:

  This PR contains some of the changes left as TODO in #11167 (and built on top of that PR). They are not intended for backporting.

  This removes the `CBase58`, `CBitcoinSecret`, `CBitcoinExtKey`, and `CBitcoinExtPubKey` classes, in favor of simple `Encode`/`Decode` functions. Furthermore, all Bitcoin-specific logic (addresses, WIF, BIP32) is moved to `key_io.{h,cpp}`, leaving `base58.{h,cpp}` as a pure utility that implements the base58 encoding/decoding logic.

be8ab7d082 Create new wallet databases as directories rather than files
This change should make it easier for users to make complete backups of wallets
because they can now just back up the specified `-wallet=<path>` path directly,
instead of having to back up the specified path as well as the transaction log
directory (for incompletely flushed wallets).

Another advantage of this change is that if two wallets are located in the same
directory, they will now use their own BerkeleyDB environments instead using a
shared environment. Using a shared environment makes it difficult to manage and
back up wallets separately because transaction log files will contain a mix of
data from all wallets in the environment.

7ba2d57852 Fix ListCoins test failure due to unset g_wallet_allow_fallback_fee
New global variables were introduced in #11882 and not setting them causes:

    wallet/test/wallet_tests.cpp(638): error in "ListCoins": check wallet->CreateTransaction({recipient}, wtx, reservekey, fee, changePos, error, dummy) failed
    wallet/test/wallet_tests.cpp(679): error in "ListCoins": check list.begin()->second.size() == 2 failed [1 != 2]

    wallet/test/wallet_tests.cpp(705): error in "ListCoins": check list.begin()->second.size() == 2 failed [1 != 2]

It's possible to reproduce the failure reliably by running:

    src/test/test_bitcoin --log_level=test_suite --run_test=wallet_tests/ListCoins

Failures happen nondeterministically because boost test framework doesn't run
tests in a specified order, and tests that run previously can set the global
variables and mask the bug.

596c446 [wallet] use P2WPKH change output if any destination is P2WPKH or P2WSH (Sjors Provoost)

Pull request description:

  If `-changetype` is not explicitly set, then regardless of `-addresstype`, the wallet will use a ~`bech32` change address~ `P2WPKH` change output if any destination is `P2WPKH` or `P2WSH`.

  This seems more intuitive to me and more in line with the spirit of [BIP-69](https://github.com/bitcoin/bips/blob/master/bip-0069.mediawiki).

  When combined with #11991 a QT user could opt to use `bech32` exclusively without having to figure out how to launch with `-changetype=bech32`, although so would #11937.

Pull request description:

  This implements a minimum viable implementation of SegWit wallet support, based on top of #11389, and includes part of the functionality from #11089.

  Two new configuration options are added:
  * `-addresstype`, with options `legacy`, `p2sh`, and `bech32`. It controls what kind of addresses are produced by `getnewaddress`, `getaccountaddress`, and `createmultisigaddress`.
  * `-changetype`, with the same options, and by default equal to `-addresstype`, that controls what kind of change is used.

  All wallet private and public keys can be used for any type of address. Support for address types dependent on different derivation paths will need a major overhaul of how our internal detection of outputs work. I expect that that will happen for a next major version.

  The above also applies to imported keys, as having a distinction there but not for normal operations is a disaster for testing, and probably for comprehension of users. This has some ugly effects, like needing to associate the provided label to `importprivkey` with each style address for the corresponding key.

  To deal with witness outputs requiring a corresponding redeemscript in wallet, three approaches are used:
  * All SegWit addresses created through `getnewaddress` or multisig RPCs explicitly get their redeemscripts added to the wallet file. This means that downgrading after creating a witness address will work, as long as the wallet file is up to date.
  * All SegWit keys in the wallet get an _implicit_ redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software.
  * All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a witness address will work.

  These approaches correspond to solutions 3a, 1a, and 5a respectively from https://gist.github.com/sipa/125cfa1615946d0c3f3eec2ad7f250a2. As argued there, there is no full solution for dealing with the case where you both downgrade and restore a backup, so that's also not implemented.

  `dumpwallet`, `importwallet`, `importmulti`, `signmessage` and `verifymessage` don't work with SegWit addresses yet. They're remaining TODOs, for this PR or a follow-up. Because of that, several tests unexpectedly run with `-addresstype=legacy` for now.

940a21932b SegWit wallet support
This introduces two command line flags (-addresstype and -changetype) which control
the type of addresses/outputs created by the GUI and RPCs. Certain RPCs allow
overriding these (`getnewaddress` and `getrawchangeaddress`). Supported types
are "legacy" (P2PKH and P2SH-multisig), "p2sh-segwit" (P2SH-P2WPKH and P2SH-P2WSH-multisig),
and "bech32" (P2WPKH and P2WSH-multisig).

A few utility functions are added to the wallet to construct different address type
and to add the necessary entries to the wallet file to be compatible with earlier
versions (see `CWallet::LearnRelatedScripts`, `GetDestinationForKey`,
`GetAllDestinationsForKey`, `CWallet::AddAndGetDestinationForScript`).

Pull request description:

  The `CTransaction&()` operator in `CMerkleTx` makes conversion into `CTransaction`s transparent, but was marked as to-be-removed in favor of explicitly getting the `tx` ivar, presumably as the operator can lead to ambiguous behavior and makes the code harder to follow.

  This PR removes the operator and adapts callers. This includes some cases of `static_cast<CTransaction>(wtx)` → `*wtx.tx`, which is definitely an improvement.

17220d6325 Use callbacks to cache whether wallet transactions are in mempool
This avoid calling out to mempool state during coin selection,
balance calculation, etc. In the next commit we ensure all wallet
callbacks from CValidationInterface happen in the same queue,
serialized with each other. This helps to avoid re-introducing one
of the issues described in #9584 [1] by further disconnecting
wallet from current chain/mempool state.

Thanks to @morcos for the suggestion to do this.

Note that there are several race conditions introduced here:

 * If a user calls sendrawtransaction from RPC, adding a
   transaction which is "trusted" (ie from them) and pays them
   change, it may not be immediately used by coin selection until
   the notification callbacks finish running. No such race is
   introduced in normal transaction-sending RPCs as this case is
   explicitly handled.

 * Until Block{Connected,Disconnected} and
   TransactionAddedToMempool calls also run in the CSceduler
   background thread, there is a race where
   TransactionAddedToMempool might be called after a
   Block{Connected,Disconnected} call happens.

 * Wallet will write a new best chain from the SetBestChain
   callback prior to having processed the transaction from that
   block.

[1] "you could go to select coins, need to use 0-conf change, but
such 0-conf change may have been included in a block who's
callbacks have not yet been processed - resulting in thinking they
are not in mempool and, thus, not selectable."

Pull request description:

  This fixes an issue where estimatesmartfee which matches at the min relay fee will return 999 sat/byte instead of 1000 sat/byte due to a float rounding issue. I went ahead and made all float <-> int conversion outside of test/qt explicit (test only had one or two more, Qt had quite a few, including many in the Qt headers themselves) and added overloads to CFeeRate to force callers to do an explicit round themselves. Easy to test with -Wfloat-conversion.

  First commit just removes default arguments from `AcceptToMemoryPool` and consolidates two arguments, it does not change behavior.

  Second commit finally fixes the fact that we're not meant to reject based on mempool min fee when adding a transaction from a disconnected block during a reorg as mentioned [here](https://github.com/bitcoin/bitcoin/pull/9602#issue-202197849)

  Third commit makes fee estimation ignore transactions added from a disconnected block during a reorg. I think this was another source of fee estimates returning estimates below 1000 sat/kB as in #11303.

  It includes a reformatted version of the [C++ Bech32 reference code](https://github.com/sipa/bech32/tree/master/ref/c%2B%2B) and an independent implementation of the address encoding/decoding logic (integrated with CTxDestination). All BIP173 test vectors are included.

  Not included (and intended for other PRs):
  * Full wallet support for SegWit (which would include automatically adding witness scripts to the wallet during automatic keypool topup, SegWit change outputs, ...) [see #11403]
  * Splitting base58.cpp and tests/base58_tests.cpp up into base58-specific code, and "address encoding"-code [see #11372]

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.

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".

e53615b443 Remove vchDefaultKey and have better first run detection
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.

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)

  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).

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.

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.

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)

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.

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

       #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 .

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

253cd7ec4f Only reserve key for scriptChange once in CreateTransaction
This does not affect behavior but allows us to have access to an output to
scriptChange even if we currently do not have change in the transaction.

f0bf33da83 Change default fee estimation mode.
Fee estimates will default to be non-conservative if the transaction in question is opt-in-RBF.

d507c301bc Introduce a fee estimate mode.
GetMinimumFee now passes the conservative argument into estimateSmartFee.
Call CalculateEstimateType(mode) before calling GetMinimumFee or estimateSmartFee to determine the value of this argument.
CCoinControl can now be used to control this mode.

This way CWallet::RescanFromTime callers don't need to subtract
TIMESTAMP_WINDOW themselves.
