fad63eb [logging] Don't incorrectly log that REJECT messages are unknown. (John Newbery)
Pull request description:
Reject messages are logged to debug.log if NET debug logging is enabled.
Because of the way the `ProcessMessages()` function is structured,
processing for REJECT messages will also drop through to the default
branch and incorrectly log `Unknown command "reject" from peer-?`. Fix
that by exiting from `ProcessMessages()` early.

fa6c3dea420b6c50c164ccc34f4e9e8a7d9a8022 p2p: Clarify control flow in ProcessMessage() (MarcoFalke)
Pull request description:
`ProcessMessage` is effectively a massive switch case construct. In the past there were attempts to clarify the control flow in `ProcessMessage()` by moving each case into a separate static function (see #9608). It was closed because it wasn't clear if moving each case into a function was the right approach.
Though, we can quasi treat each case as a function by adding a return statement to each case. (Can be seen as a continuation of bugfix #13162)
This patch does exactly that.
Also note that this patch is a subset of previous approaches such as #9608 and #10145.

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...

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.

3e1ee31 [Tests] Adding unit tests for GetDifficulty in blockchain.cpp. (sean)
Pull request description:
blockchain.cpp has low unit test coverage. This commit is intended
to start improving its code coverage to reasonable levels. One or more
follow up commits will complete the task that this commit is starting
(though the usefulness of this commit is not dependent upon later
commits).
Note that these tests were not written based upon a specification of how
GetDifficulty *should* work, but rather how it actually *does* work. As
a result, if there are any bugs in the current GetDifficulty
implementation, these unit tests serve to lock them in rather than
expose them.
-- Why has blockchain.cpp been modified if this is a unit testing change?
Since the existing GetDifficulty function relies on a global variable,
chainActive, it was not suitable for unit testing purposes. Both the
existing GetDifficulty function and the unit tests now call through to
a new, more modular version of GetDifficulty that can work on any chain,
not just chainActive.
-- Why does blockchain_tests.cpp directly include blockchain.cpp instead
of blockchain.h?
While the new GetDifficulty function's signature is arguably better than
the old one's, it still isn't great, and doesn't seem to warrant inclusion
as part of the blockchain.h API, especially since only test code is
directly using it. If a better way of exposing the new GetDifficulty
function to unit tests exists, please mention it and the commit will be
updated accordingly.
-- Why is the test fixture named blockchain_difficulty_tests rather than
blockchain_tests?
The Bitcoin Core policy for naming unit test files is to match the the
file under test ("blockchain" becomes "blockchain_tests"). While this
commit complies with that, blockchain.cpp is a massive file, such that
having all of the unit tests in one file will tend towards disorder.
Since there will be a lot more tests added to this file, the intention
is to divide up different types of tests into different test fixtures
within the same file.

2862b56 [tests] remove redundant univalue_tests.cpp (John Newbery)
Pull request description:
univalue unit tests were added in #4730 , and exist at `/src/test/univalue_tests.cpp` (outside the univalue tree). That test was brought into the univalue repository in https://github.com/bitcoin-core/univalue/pull/4 , which was pulled into the github repository in https://github.com/bitcoin/bitcoin/pull/11420.
That means that the univalue test exists in two places:
1. `/src/test/univalue_tests.cpp`
2. `/src/univalue/test/object.cpp`
(2) is a strict superset of (1). It adds some macros to work around boost not being a univalue dependency, and adds a few extra lines of test.
Therefore remove `/src/test/univalue_tests.cpp`

This patch adds an option to configure the name and/or directory of the debug log file.
The user can specify either a relative path, in which case the path is relative to the (network specific) data directory. They can also specify an absolute path to put the log anywhere else in the file system.
Alternative to #11741 that gets rid of the concept of a "log directory" by specifying the path for the specific kind of log, the debug log. Which happens to be the only kind of log we have at this point*, but a hypothetical new kind of log (say, an audit log) would get a new option. This has more flexibility than specifying a directory which has to contain all of them.
\* excluding `db.log` which is internally generated by the wallet database library, but that one moves along with `-walletdir`.

9b80fc1 Prefix leveldb debug logging (Wladimir J. van der Laan)
Pull request description:
Add leveldb: prefix to leveldb debug logging lines.
leveldb debug messages come in various scary flavors such as:
2017-11-30 08:26:31 leveldb: Recovering log #26
2017-11-30 08:26:31 leveldb: Level-0 table #28: started

2017-11-30 08:26:31 leveldb: Delete type=3 #24
so it's reasonably important to mark them as coming from leveldb internals and not from consensus validation wallet or such.
This is consistent with the `libevent:` prefix for libevent messages.
(this only affects `-debug=leveldb` or `-debug=1` otherwise you won't see them in the first place)
