[Tests] check specific validation error in miner tests
BOOST_CHECK_THROW merely checks that some std::runtime_error is
thrown, but not which one.

One example of how this could lead to a test passing when a developer
introduces a consensus bug: the test for the sigops limit assumes
that CreateNewBlock fails with bad-blk-sigops. However it can
also fail with bad-txns-vout-negative, e.g. if a naive developer lowers
BLOCKSUBSIDY to 1*COIN in the test.

BOOST_CHECK_EXCEPTION allows an additional predicate function. This
commit uses this for all exceptions that are checked for in
miner_tets.cpp:
* bad-blk-sigops
* bad-cb-multiple
* bad-txns-inputs-missingorspent
* block-validation-failed

An instance of the CheckRejectInvalid class (for a given validation string)
is passed to BOOST_CHECK_EXCEPTION.

18e071841 [consensus] Pin P2SH activation to block 173805 on mainnet (John Newbery)
526023aa7 Improve handling of BIP9Deployment limits (Anthony Towns)

Pull request description:

  Most tests shouldn't have to deal with the now-historical SegWit activation transition (and other deployments, but SegWit is certainly the hardest one to accomodate).

  This PR makes a versionbits starttime of -1 equal to "always active", and enables it by default for SegWit on regtest. Individual tests can override this by using the existing `-vbparams` option.

  A few unit tests and functional tests are adapted to indeed override vbparams, as they specifically test the transition.

  This is in preparation for wallet SegWit support, but I thought having earlier eyes on it would be useful.

If our tip hasn't updated in a while, that may be because our peers are
not relaying blocks to us that we would consider valid. Allow connection
to an additional outbound peer in that circumstance.

Also, periodically check to see if we are exceeding our target number of
outbound peers, and disconnect the one which has least recently
announced a new block to us (choosing the newest such peer in the case
of tie).

Merge #10099: Slightly Improve Unit Tests for Checkqueue
8c2f4b888 Expose more parallelism with relaxed atomics (suggested in #9938). Fix a test to check the exclusive or of two properties rather than just or. (Jeremy Rubin)

Pull request description:

  This PR is in response to #10026 and some feedback on #9938.

  ~Locally, all the checkqueue tests ran 3.2X faster on my machine. The worst offender, `test_CheckQueue_Correct_Random` ran 3.4X faster.~

  1. ~Removes `GetRand()` and replaces it with a single deterministic FastRandomContext instance.~ #10321 replicated this

  1. Exposes more parallelism with relaxed atomics, increasing chance of catching a bug. This does not change performance on my machine.

  1. Makes one test case more restrictive (xor instead of or, see #9938).

46ce223d1 Add tests for CMerkleBlock usage with txids specified (James O'Beirne)
5ab586f90 Consolidate CMerkleBlock constructor into a single method (James O'Beirne)

Pull request description:

  What started as a simple task to add test coverage ended up giving way to a light refactoring. This consolidates the mostly-identical `CMerkleBlock` constructors into one (using C++11 constructor delegation) and adds coverage for the by-txids construction case.

Merge #11284: Fix invalid memory access in CScript::operator+= (guidovranken, ajtowns)
d601f16 Fix invalid memory access in CScript::operator+= (Anthony Towns)

Pull request description:

  This is a fix for #11114 -- invoking "s += s" gets turned into "s.insert(s.end(), s.begin(), s.end())" which can result in an invalid memory access is s.capacity() < 2*s.size() (because s gets resized and possibly moved, so s.begin() and s.end() become invalid references when reading the values to be appended).

  The fix is straightforward: reserve enough space in advance, so that insert() doesn't need to resize and thus its arguments remain valid.

  A simple test case is added as well; though you probably need to run it via valgrind to actually catch the problem when it's not fixed...

53a6590f4 Make float <-> int casts explicit outside of test, qt, CFeeRate (Matt Corallo)
0b1b9148c Remove countMaskInv caching in bench framework (Matt Corallo)

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.

04f78ab5b Do not reject based on mempool min fee when bypass_limits is set. (Alex Morcos)
fd849e1b0 Change AcceptToMemoryPool function signature (Alex Morcos)

Pull request description:

  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.

9ad6746ccd Use static_cast instead of C-style casts for non-fundamental types
A C-style cast is equivalent to try casting in the following order:

1. const_cast(...)
2. static_cast(...)
3. const_cast(static_cast(...))
4. reinterpret_cast(...)
5. const_cast(reinterpret_cast(...))

By using static_cast<T>(...) explicitly we avoid the possibility
of an unintentional and dangerous reinterpret_cast. Furthermore
static_cast<T>(...) allows for easier grepping of casts.

  This patch removes the need for the intermediary Base58 type `CBitcoinAddress`, by providing {`Encode`,`Decode`,`IsValid`}`Destination` functions that directly operate on the conversion between `std::string`s and `CTxDestination`.

  As a side, it also fixes a number of indentation issues, and removes probably several unnecessary implicit `CTxDestination`<->`CBitcoinAddress` conversions.

  This change is far from complete. In follow-ups I'd like to:
  * Split off the specific address and key encoding logic from base58.h, and move it to a address.h or so.
  * Replace `CTxDestination` with a non-`boost::variant` version (which can be more efficient as `boost::variant` allocates everything on the heap, and remove the need for `boost::get<...>` and `IsValidDestination` calls everywhere).
  * Do the same for `CBitcoinSecret`, `CBitcoinExtKey`, and `CBitcoinExtPubKey`.

  However, I've tried to keep this patch to be minimally invasive, but still enough to support non-Base58 addresses. Perhaps a smaller patch is possible to hack Bech32 support into `CBitcoinAddress`, but I would consider that a move in the wrong direction.

0311836f6 Allow setting nMinimumChainWork on command line (Suhas Daftuar)

Pull request description:

  As discussed briefly here: https://botbot.me/freenode/bitcoin-core-dev/2017-02-28/?msg=81712308&page=4

  This adds a hidden command line option for setting `nMinimumChainWork`, which allows us to test this parameter in our functional tests, as well as allowing for niche use cases like syncing nodes that are otherwise disconnected from the network.

  See also #10345, which proposes a new use of `nMinimumChainWork`.

946638d0a0 Improve versionbits_computeblockversion test code consistency
In this test, `nTime` is used for all the calls to `Mine()`, each time being set to the correct time beforehand, except for in the last few calls to `Mine()` where `nStartTime` is used directly, even though `nTime` is still set to `nStartTime` beforehand. `nTime` just remains unused for these last few calls to `Mine()`.

Changed the last few calls to `Mine()` to use `nTime` instead, improving consistency. This also fixes an unused value static analyzer warning about `nTime` being set to a value which is never used.

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)

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.

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.

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.

  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

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.

changes to policy/fees.cpp include a big whitespace indentation change.

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.

This moves SplitHostPort from libbitcoin_common to libbitcoin_util so it
is available to bitcoin-cli.

c8e29d7ff0 Replace MAX_OPCODE for OP_NOP10.
That OP_NOP10 is the last executable opcode is a bit of a obscure trivia, and the MAX_OPCODE constant already exists. This merely standardizes use of MAX_OPCODE over OP_NOP10 where it makes sense and is more clear.

3192975f1d Flush CValidationInterface callbacks prior to destruction
Note that the CScheduler thread cant be running at this point,
it has already been stopped with the rest of the init threadgroup.
Thus, just calling any remaining loose callbacks during Shutdown()
is sane.
