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.

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...

bb8376b Verify DBWrapper iterators are taking snapshots (Matt Corallo)
Pull request description:
The LevelDB docs seem to indicate that an iterator will not take
snapshots (even providing instructions on how to do so yourself).
In several of the places we use them, we assume snapshots to have
been taken.
In order to make sure LevelDB doesn't change out from under us
(and to prevent the next person who reads the docs from having the
same fright I did), verify that snapshots are taken in our tests.

1789e4675 Force explicit double -> int conversion for CFeeRate constructor (Matt Corallo)
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.

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.

Combine fLimitFree and fOverrideMempoolLimit into a single boolean:
bypass_limits. This is used to indicate that mempool limiting based on feerate
should be bypassed. It is used when readding transactions from a reorg and then
the mempool is trimmed to size after all transactions are added and they can be
evaluated in the context of their descendants. No changes to behavior.
This resolves an issue where estimatesmartfee would return 999
sat/byte instead of 1000, due to floating point loss of precision

864cd2787 Move CBitcoinAddress to base58.cpp (Pieter Wuille)
5c8ff0d44 Introduce wrappers around CBitcoinAddress (Pieter Wuille)
Pull request description:
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.

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`.

`make` rebuilds the entire project. This is quite slow if e.g. you're making changes to one file and only wish to run the bitcoind tests.
This commit adds an instruction to run `make -C src/test` (as opposed to `make src/test` and `make src/test/test_bitcoin`).
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)

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.
