b82c55a Add attribute [[noreturn]] (C++11) to functions that will not return (practicalswift)

Pull request description:

  Add attribute `[[noreturn]]` (C++11) to functions that will not return.

  Rationale:
  * Reduce the number of false positives/false negatives from static analyzers with regards to things such as unused or unreachable code
  * Potentially enable additional compiler optimizations

Merge #10483: scripted-diff: Use the C++11 keyword nullptr to denote the pointer literal instead of the macro NULL
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)

46347add43 rpc: Move ValueFromAmount to core_write
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.

b0f3249 More user-friendly error message if UTXO DB runs ahead of block DB (Matt Corallo)
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.

c1ccb15 Add SSE4 based SHA256 (Pieter Wuille)
2991c91 Add SHA256 dispatcher (Pieter Wuille)
4d50f38 Support multi-block SHA256 transforms (Pieter Wuille)

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.

b1385852ef Remove factor of 3 from definition of dust.
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.

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.

Merge #10812: [utils] Allow bitcoin-cli's -rpcconnect option to be used with square brackets
5c643241e [utils] allow square brackets for ipv6 addresses in bitcoin-cli (John Newbery)
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
  - second commit adds proper ipv6 parsing to bitcoin-cli

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.

3babbcb487 Remove confusing MAX_BLOCK_BASE_SIZE.
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.

21180ff734 Simplify return values of GetCoin/HaveCoin(InCache)
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.

7f31762cb6 net: add an internal subnet for representing unresolved hostnames
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).

b5fea8d0cc Cache full script execution results in addition to signatures
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.

5083079688 Switch CCoinsView and chainstate db from per-txid to per-txout
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.

c87b957a32 Only pass things committed to by tx's witness hash to CScriptCheck
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.

cb2c7fdac2 Replace CTxInUndo with Coin
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.
