Instead of using ismine to check whether an address can be spent by us,
make the witness version of the script or address first and then use
ProduceSignature with the DummySignatureCreator to check if we can
solve for the script.
Also fixes test cases to reflect this change.
* Order chainstate init more logically - first all of the
blocktree-related loading, then coinsdb, then
pcoinsTip/chainActive. Only create objects as needed.
* More clearly document exactly what is and isn't called in
-reindex and -reindex-chainstate both with comments noting
calls as no-ops and by adding if guards.
* Move LoadGenesisBlock further down in init. This is a more logical
location for it, as it is after all of the blockindex-related
loading and checking, but before any of the UTXO-related loading
and checking.
* Move all of the VerifyDB()-related stuff into a -reindex +
-reindex-chainstate if guard. It couldn't do anything useful
as chainActive.Tip() would be null at this point anyway.
RewindBlockIndex works over both chainActive - disconnecting blocks
from the tip that need witness verification - and mapBlockIndex -
requiring redownload of blocks missing witness data.
It should never have been the case that the second half is skipped
if we're about to run -reindex-chainstate.
This gives LoadChainTip a return value - allowing it to indicate that
the UTXO DB ran ahead of the block DB. This just provides a nicer
error message instead of the previous mysterious
assert(!setBlockIndexCandidates.empty()) error.
This also calls ActivateBestChain in case we just loaded the genesis
block in LoadChainTip, avoiding relying on the ActivateBestChain
in ThreadImport before continuing init process.
* Move the writing of fTxIndex to LoadBlockIndex - this fixes a
bug introduced in d6af06d68a where
InitBlockIndex was writing to fTxIndex which had not yet been
checked (because LoadChainTip hadn't yet initialized the
chainActive, which would otherwise have resulted in
InitBlockIndex being a NOP), allowing you to modify -txindex
without reindex, potentially corrupting your chainstate!
* Rename InitBlockIndex to LoadGenesisBlock, which is now a more
natural name for it. Also check mapBlockIndex instead of
chainActive, fixing a bug where we'd write the genesis block out
on every start.

`setenv` function is not available from the Microsoft runtime library. Need to use `_putenv_s` instead.
This solution tells the compiler to use `_putenv_s` on `WIN32` compilation (Note: this also works on 64-bit Windows instances.) and `setenv` everywhere else.
I've tested builds on Windows 10 x64 and Ubuntu 16.04 with this code.

9737572 [Qt] Use wallet 0 in rpc console if running with multiple wallets (Jonas Schnelli)
Pull request description:
Current master with multiwallet results in accessing wallet 0 in QT (send / receive / tx history / etc.), **but** the RPC console cannot access that wallet (only non-wallet commands work).
This is a quick solution to re-allow accessing the same wallet (Index 0) via RPC console in multiwallet.
The solutions design is not "state of the art" (should go over WalletModel). Ideally we work on an overall multiwallet support for the GUI (which then would remove this change).
I think we should consider this as a bugfix.

Readability, SetSocketNonBlocking does what it says on the tin.
Consistency, More consistent with the rest of the API in this unit.
Reusability, SetSocketNonBlocking can also be used by clients that may not want to close the socket on failure.
This also moves the responsibility of closing the socket back to the caller that opened it, which in general should know better how and when to close it.

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.

Pull request description:
This adds an SSE4 assembly version of the SHA256 transform by Intel, and uses it at run time if SSE4 instructions are available, and use a fallback C++ implementation otherwise. Nearly every x86_64 CPU supports SSE4. The feature is only enabled when compiled with `--enable-experimental-asm`.
In order to avoid build dependencies and other complications, the original Intel YASM code was translated to GCC extended asm syntax.
This gives around a 50% speedup on the SHA256 benchmark for me.
It is based on an earlier patch by @laanwj, though only includes a single assembly version (for now), and removes the YASM dependency.

These lines confuse me.
Correct me if I am wrong, but we can't check any more blocks than we have right?
If someone requests <= 0 it get set it into some huge number and then immediately limit it to the chain height in the following statement.
````
if (nCheckDepth > chainActive.Height())
nCheckDepth = chainActive.Height();
````
when using ````--checkblocks=Z```` When Z is ````0```` or any other negative number, it will check all blocks.
I think it should be changed to this maybe.
````
if (nCheckDepth <= 0 || nCheckDepth > chainActive.Height())
nCheckDepth = chainActive.Height();
````
Which gets rid of that huge number which is confusing for any other altcoins that have a different block time.

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.

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

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!

06bcdb8da Convert named argument from nblocks to conf_target (Alex Morcos)
439c4e8ad Improve api to estimatesmartfee (Alex Morcos)
Pull request description:
Through 0.14 branch, the estimatesmartfee API was tagged "WARNING: This interface is unstable and may disappear or change!" and this warning is removed for 0.15, so any wanted API updates should happen now.
The changes here are to make the additional parameter for conservative estimates a more general estimate_mode string , to omit the feerate and include an error string instead of returning -1 on error, and to do better parameter checking initially.
~It is only the last 2 commits, but it's built on #10706 and #10543~.
See https://github.com/bitcoin/bitcoin/pull/10707#issuecomment-314869251 for renaming of nblocks argument to conf_target. Will need to be included before string freeze.

This can happen if we some how a merkle tree with zero txids. I don't think this can happen in practice as we only send merkle block messages on the p2p network as of now -- we cannot receive them.

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.

This redefines dust 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.

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 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 .

fe4fabaf1 [refactor] move SplitHostPort() into utilstrencodings (John Newbery)
Pull request description:
bitcoin-cli's `-rpcconnect` can accept ipv6 addresses (as long as the libevent version is new enough), but fails to parse ipv6 with square brackets. This PR makes `bitcoin-cli` parse ipv6 in square brackets correctly.
`bitcoin-cli -rpcconnect=[::1] <command>`
should now be equivalent to
`bitcoin-cli -rpcconnect=::1 <command>`
This is useful so the `bitcoin-cli` option can now be in the same format as the `bitcoind` option.
Doesn't include tests. I have a branch that fully tests `bitcoin-cli`, but that's queued behind several intermediate PRs.
- first commit moves `SplitHostPort()` from libbitcoin_common into libbitcoin_util

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.
changes to policy/fees.cpp include a big whitespace indentation change.
Remove helper function (CalculateEstimateType) for determining whether
estimates should be conservative or not, now that this is only called
once from GetMinimumFee and incorporate the logic directly there.
This fixes buggy behavior where we were temporarily setting and unsetting the
global payTxFee when trying to send a transaction with a custom fee from the
GUI. The previous behavior was inconsistent depending on the order of using the
RPC call settxfee and clicking various radio buttons in the sendcoinsdialog.
The new behavior is that transactions sent with the GUI will always use either
the smartfee slider value or the custom fee set on the GUI and they will not
affect the global defaults which are only for RPC and initial GUI values.

Some people keep thinking that MAX_BLOCK_BASE_SIZE is a separate
size limit from the weight limit when it fact it is superfluous,
and used in early tests before the witness data has been
validated or just to compute worst case sizes. The size checks
that use it would not behave any differently consensus wise
if they were eliminated completely.
Its correct value is not independently settable but is a function
of the weight limit and weight formula.
This patch just eliminates it and uses the scale factor as
required to compute the worse case constants.
It also moves the weight factor out of primitives into consensus,
which is a more logical place for it.

Removing EOL whitespace
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.

Use __func__ macro in std::runtime_exception to:
1. fix method name in CWalletTx::GetAvailableWatchOnlyCredit()
2. refactor CWalletTx::GetAvailableCredit()
(by hiding boost::signals stuff in the .cpp)
This allows us to give it a bit more intelligence as we move
forward, including routing some signals through CScheduler. While
the introduction of a "internals" pointer in the class is pretty
ugly, the fact that we no longer need to include boost/signals
directly from validationinterface.h is very much worth the loss.

This makes it possible to mine to any wallet when multi-wallet mode is added.
Solves the same problem as #10649, but IMO in a cleaner way.
It also gets rid of the circuitous `ScriptForMining` method on
`CValidationInterface`, which really doesn't belong there.
After this change it's still possible to mine without wallet through
`generatetoaddress`.

Check that cached script execution results are only valid for the same
script flags; that script execution checks are returned for non-cached
transactions; and that cached results are only valid for transactions
with the same witness hash.
Checking for the existence in the CCoinsViewCache of the outputs of a new tx
will result in a disk hit for every output since they will not be found. On the
other hand if those outputs exist already, then the inputs must also have been
missing, so we can move this check inside the input existence check so in the
common case of a new tx it doesn't need to run.
The purpose of the check is to avoid spamming the orphanMap with slightly old
txs which we have already seen in a block, but it is already only optimistic
(depending on the outputs not being spent), so make it even more efficient by
only checking the cache and not the entire pcoinsTip.

This removes the possibility for GetCoin/HaveCoin/HaveCoinInCache to return
true while the respective coin is spent. By doing it across all calls, some
extra checks can be eliminated.
coins_tests is modified to call HaveCoin sometimes before and sometimes
after AccessCoin. A further change is needed because the semantics for
GetCoin slightly changed, causing a pruned entry in the parent cache to not
be pulled into the child in FetchCoin.
Adds new functional test, dbcrash.py, which uses -dbcrashratio to exercise the
logic for recovering from a crash during chainstate flush.
dbcrash.py is added to the extended tests, as it may take ~10 minutes to run
Use _Exit() instead of exit() for crash simulation
This eliminates stderr output such as:
terminate called without an active exception
or
Assertion failed: (!pthread_mutex_destroy(&m)), function ~recursive_mutex, file /usr/local/include/boost/thread/pthread/recursive_mutex.hpp, line 104.
Eliminating the stderr output on crash simulation allows testing with
test_runner.py, which reports a test as failed if stderr is produced.
This requires that we not access pcoinsTip in InitBlockIndex's
FlushStateToDisk (so we just skip it until later in AppInitMain)
and the LoadChainTip in LoadBlockIndex (which there is already one
later in AppinitMain, after ReplayBlocks, so skipping it there is
fine).
Includes some simplifications by Suhas Daftuar and Pieter Wuille.

In order to prevent mixups, our internal range is never allowed as a resolve
result. This means that no user-provided string will ever be confused with an
internal address.
We currently do two resolves for dns seeds: one for the results, and one to
serve in addrman as the source for those addresses.
There's no requirement that the source hostname resolves to the stored
identifier, only that the mapping is unique. So rather than incurring the
second lookup, combine a private subnet with a hash of the hostname.
The resulting v6 ip is guaranteed not to be publicy routable, and has only a
negligible chance of colliding with a user's internal network (which would be
of no consequence anyway).
Since cfe77ef41 the global nTxConfirmTarget wasn't being updated by the smart
fee slider and thus the coin control dialog and labels were not being updated.

In Olaoluwa Osuntokun's recent protocol proposal they were using a
mod in an inner loop. I wanted to suggest a normative protocol
change to use the trick we use here, but to find an explanation
of it I had to dig up the PR on github. After I posted about it
several other developers commented that it was very interesting
and they were unaware of it.
I think ideally the code should be self documenting and help
educate other contributors about non-obvious techniques that
we use. So I've written a description of the technique with
citations for future reference.

While the current implementation is pretty free, there is a lot
of possibility for this to blow up in our face with future changes,
especially as the backing map gets tweaked.
There are some similar asserts which are left removed in policy
and ATMP (policy code being broken isn't a huge deal, but if we
fail to verify some consensus rules, we should most definitely
crash).
Previously it was possible for HaveCoinInCache to return true for a spent
coin. It is more clear to keep the semantics the same. HaveCoinInCache is
used for two reasons:
- tracking coins we may want to uncache, in which case it is unlikely there
would be spent coins we could uncache (not dirty)
- optimistically checking whether we have already included a tx in the
blockchain, in which case a spent coin is not a reliable indicator that we have.

We can call gettxoutproof() with a list of transactions. Currently, if
the first transaction is unspent (and all other transactions are in the
same block), then the call will succeed. If the first transaction has
been spent, then the call will fail. The means that the following two
calls will return different results:
gettxoutproof(unspent_tx1, spent_tx1)
gettxoutproof(spent_tx1, unspent_tx1)
This commit makes behaviour independent of transaction ordering by looping
through all transactions provided and trying to find which block they're in.
This commit also increases the test coverage and tests more failure
cases for gettxoutproof()
Added an option to configure to allow for branch coverage statistics gathering.
Disabled logprint macro when coverage testing is on so that unnecessary branches are not analyzed.
The implementation of base_uint::operator++(int) and base_uint::operator--(int) is now safer.
Array pn is accessed via index i after bounds checking has been performed on the index, rather than before.
The logic of the while loops has also been made more clear.
A compile time assertion has been added in the class constructors to ensure that BITS is a positive multiple of 32.
CCoinsViewCache doesn't actually support cursor iteration returning the
current contents of the cache, so raise an error when the cursor method is
called instead of returning a cursor that iterates over stale data.
Also update the gettxoutsetinfo RPC which was relying on the old behavior to be
explicit about which view it is returning data about.
This adds a new CuckooCache in validation, caching whether all of a
transaction's scripts were valid with a given set of script flags.
Unlike previous attempts at caching an entire transaction's
validity, which have nearly universally introduced consensus
failures, this only caches the validity of a transaction's
scriptSigs. As these are pure functions of the transaction and
data it commits to, this should be much safer.
This is somewhat duplicative with the sigcache, as entries in the
new cache will also have several entries in the sigcache. However,
the sigcache is kept both as ATMP relies on it and because it
prevents malleability-based DoS attacks on the new higher-level
cache. Instead, the -sigcachesize option is re-used - cutting the
sigcache size in half and using the newly freed memory for the
script execution cache.
Transactions which match the script execution cache never even have
entries in the script check thread's workqueue created.
Note that the cache is indexed only on the script execution flags
and the transaction's witness hash. While this is sufficient to
make the CScriptCheck() calls pure functions, this introduces
dependancies on the mempool calculating things such as the
PrecomputedTransactionData object, filling the CCoinsViewCache, etc
in the exact same way as ConnectBlock. I belive this is a reasonable
assumption, but should be noted carefully.
In a rather naive benchmark (reindex-chainstate up to block 284k
with cuckoocache always returning true for contains(),
-assumevalid=0 and a very large dbcache), this connected blocks
~1.7x faster.

Prior to per-utxo CCoins, we checked that no other in-mempool tx
spent any of the given transaction's outputs, as we don't want to
uncache that entire tx in such a case. However, we now are checking
only that there exists no other mempool spends of the same output,
which should clearly be impossible after we removed the transaction
which was spending said output (barring massive mempool
inconsistency).
Thanks to @sdaftuar for the suggestion.
At startup, we choose one peer to serve us the headers chain, until
our best header is close to caught up. Disconnect this peer if more
than 15 minutes + 1ms/expected_header passes and our best header
is still more than 1 day away from current time.
This change has no effect on wallet behavior.
On wallet startup, the transaction scan avoids reading any blocks with
timestamps older than the wallet birthday (less than nTimeFirstKey -
TIMESTAMP_WINDOW). This block skipping code currently resides in
CWallet::ScanForWalletTransactions but it doesn't really belong there because
it makes the implementation unnecessarily fragile and hard to understand, and
it never has any effect except at startup (because all other callers do their
rescans based on timestamps other than, but always greater or equal to,
nTimeFirstKey).
This adds the listening address on which incoming connections were received to the
CNode and CNodeStats structures.
The address is reported in `getpeerinfo`.
This can be useful for distinguishing connections received on different listening ports
(e.g. when using a different listening port for Tor hidden service connections)
or different networks.

As the maximum amount of data that can be pulled into the cache due to
a block validation is much lower now (at most one CCoin entry per input
and per output), reduce the conservative estimate used to determine
flushing time.
This patch makes several related changes:
* Changes the CCoinsView virtual methods (GetCoins, HaveCoins, ...)
to be COutPoint/Coin-based rather than txid/CCoins-based.
* Changes the chainstate db to a new incompatible format that is also
COutPoint/Coin based.
* Implements reconstruction code for hash_serialized_2.
* Adapts the coins_tests unit tests (thanks to Russell Yanofsky).
A side effect of the new CCoinsView model is that we can no longer
use the (unreliable) test for transaction outputs in the UTXO set
to determine whether we already have a particular transaction.
This clarifies a bit more the ways in which the new script execution
cache could break consensus in the future if additional data from
the CCoins object were to be used as a part of script execution.
After this change, any such consensus breaks should be very visible
to reviewers, hopefully ensuring no such changes can be made.
The new functions are:
* CCoinsViewCache::AddCoin: Add a single COutPoint/Coin pair.
* CCoinsViewCache::SpendCoin: Remove a single COutPoint.
* AddCoins: utility function that invokes CCoinsViewCache::AddCoin for
each output in a CTransaction.
* AccessByTxid: utility function that searches for any output with
a given txid.
* CCoinsViewCache::AccessCoin: retrieve the Coin for a COutPoint.
* CCoinsViewCache::HaveCoins: check whether a non-empty Coin exists
for a given COutPoint.
The AddCoin and SpendCoin methods will eventually replace ModifyCoins
and ModifyNewCoins, AddCoins will replace CCoins::FromTx, and the new
AccessCoins and HaveCoins functions will replace their per-txid
counterparts.
Note that AccessCoin for now returns a copy of the Coin object. In a
later commit it will be change to returning a const reference (which
keeps working in all call sites).
The earlier CTxInUndo class now holds the same information as the Coin
class. Instead of duplicating functionality, replace CTxInUndo with a
serialization adapter for Coin.

Previously, transaction metadata (height, coinbase or not, and before
the previous commit also nVersion) was only stored for undo records
that correspond to the last output of a transaction being spent.
This only saves 2 bytes per undo record. Change this to storing this
information for every undo record, and stop complaining for having it
in non-last output spends. This means that undo dat written with
this patch won't be readable by older versions anymore.
