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)

This PR contains the first part of #10882 :
- if a key from the keypool is used, mark all keys up to that key as used, and then try to top up the keypool
- 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).

Pull request description:
With this, the amounts returned in `decoderawtransaction` will be padded to 8 digits like anywhere else in the API.
This is accomplished by using `ValueFromAmount` in `TxToUniv`, instead of `FormatMoney` which it currently (mistakingly) uses. The `FormatMoney` function is only for debugging/logging use!
To avoid dependency issues, `ValueFromAmount` is moved to `core_write.cpp`, where it also fits better. I don't move `AmountFromValue` to `core_read.cpp` at the same time, as this would have more impact due to the RPCError dependency there.
(n.b.: large number of changed files is solely due to the util_tests JSONs needing update)

This is necessary because core_write has to write amounts in
TxToUniv, and mistakingly uses FormatMoney for that
(which is only for debugging).
We don't move AmountFromValue at the same time, as
this is more challenging due to the RPCError depencency
there.

1de73f4 Disconnect network service bits 6 and 8 until Aug 1, 2018 (Matt Corallo)
Pull request description:
Immediately disconnect peers that use service bits 6 and 8 until August 1st, 2018
These bits have been used as a flag to indicate that a node is running incompatible
consensus rules instead of changing the network magic, so we're stuck disconnecting
based on the service bits, at least for a while.
Staying connected to nodes on other networks only prevents both sides from reaching consensus quickly, wastes network resources on both sides, etc.
Didn't add constants to protocol.h as the code there notes that "service bits should be allocated via the BIP process".

This fixes a few cases where we should be treating a restart-after-
coinsviewdb-reset identically to a just-reset-coinsviewdb.
Thanks to @morcos for identifying the bug.
This more clearly uses fReindex vs fReset to make sure we're not
clearing our coinsdb needlessly when restarting after a reindex.
It also makes it so that restarting after shutting down mid-reindex
isn't treates specially at all during txdb loading code, as it
shouldn't be.
This resolves a possible-assert-on-shutdown race introduced in
1f668b6468 when early shutdown
occurs.
Previously this was not done to avoid any cases where the
threadGroup might not exit due to a blocking thread, but at this
point the threadGroup isn't used all that much, plus Qt already
does this, and its good to keep their init/shutdown consistent.
For those curious, the threadGroup is only used in a few places:
* Its used to run the CCheckQueues in script validation, but these
use the boost mutex/condition variable primitives, so they
respect the interrupt pretty trivially.
* Its used for the import thread, which should exit rather quickly
as mostly it just calls LoadExternalBlockFile, which has an
interruption_point right before each block loaded.
* Its used in the scheduler thread, which is only used for:
* validationinterface has an effectively-dummy reference to it.
* wallet compaction, which should not last long
* addr/banlist dumping from CConnman, which should also be fast
e222dc2 Replace ismine with producesignature check in witnessifier (Andrew Chow)
Pull request description:
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.
This is to fix cases where we don't have all of the private keys (for something like a multisig address) but have the redeemscript so we can witnessify it.

efeb273 Force on-the-fly compaction during pertxout upgrade (Pieter Wuille)
Pull request description:
It seems that LevelDB tends to leave the old "per txid" UTXO entries in the database lying around for a significant amount of time during and after the per-txout upgrade. This introduces a `CompactRange` function in the database wrapper, and invokes it after every batch of updates in `CCoinsViewDB::Upgrade()`. This lowers temporary disk usage during and after the upgrade.

eda888e Fix some LoadChainTip-related init-order bugs. (Matt Corallo)
Pull request description:
This does a number of things to clean up chainstate init order,
fixing some issues as it goes:
* 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 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.
* 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.
* Give 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.
* Calls ActivateBestChain in case we just loaded the genesis
block in LoadChainTip, avoiding relying on the ActivateBestChain
in ThreadImport before continuing init process.
* 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.

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

* Move LoadGenesisBlock further down in init. This is a more logical
location for it, as it is after all of the blockindex-related

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

`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.

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.

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.

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

Avoid redundant redeclaration of `GetWarnings(const string&)`.
`std::string GetWarnings(const std::string& strFor)` is declared in `warnings.h` and defined in `warnings.cpp`.

Create a combinerawtransaction RPC which accepts a json array of hex raw
transactions to combine them into one transaction. Signrawtransaction is changed
to no longer combine transactions and only accept one transaction at a time.
cf82a9e Do not allow users to get keys from keypool without reserving them (Matt Corallo)
Pull request description:
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 partially reverts #9377. Would be nice to get this for 15 since its kinda crazy we have this option to begin with IMO, will need release notes as an RPC option is now ignored.

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.

Alternative for #10829 and #10650.
It adds the most simplest form of wallet based endpoint support (`/wallet/<filename>`).
No v1 and no node/wallet endpoint split.

1fc8c3d No longer ever reuse keypool indexes (Matt Corallo)
Pull request description:
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.
Builds on #10235, should probably get a 15 tag.

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.
