6ad0328f1c Don't assert(foo()) where foo has side effects (practicalswift)
Pull request description:
Don't `assert(foo())` where `foo` has side effects.
From `assert(3)`:
> If the macro `NDEBUG` is defined at the moment `<assert.h>` was last included, the macro `assert()` generates no code, and hence does nothing at all.
Bitcoin currently cannot be compiled without assertions, but we shouldn't rely on that.

ef7beaea6a Visual Studio build configuration for Bitcoin Core (Aaron Clauson)
Pull request description:
This PR allows Bitcoin Core to be relatively easily built with Visual Studio 2017. It's anticipated that it could be useful for devs familiar with Visual Studio and Microsoft's tooling. In particular the ability to use the VS debugger is a big benefit.
~~Caveats:~~
- ~~There are some minor code changes required on Bitcoin Core in order for msvc to be able to successfully compile. I'll submit them in a separate PR, The code changes are available in #11528#11558 and #11562~~.
- ~~The vcpkg for SECP256K1 has not yet been accepted by Microsoft. The files are available from this [PR](https://github.com/Microsoft/vcpkg/pull/2005) and should be copied into a vcpkg/ports/secp256k1 directory prior to vcpkg install steps.~~
**Update:** For anyone wishing to test out the Visual Studio build with the various open pull requests the steps are:
- Clone and build [Vcpkg](https://github.com/Microsoft/vcpkg) (Microsoft's new open source C/C++ package manager)
- git clone https://github.com/Microsoft/vcpkg
- .\bootstrap-vcpkg.bat
- Set up Visual Studio to automatically reference vcpkg installs: .\vcpkg integrate install
- Install the required packages (replace x86 with x64 as required):
- vcpkg install boost:x86-windows-static
- vcpkg install libevent:x86-windows-static
- vcpkg install openssl:x86-windows-static
- vcpkg install zeromq:x86-windows-static
- vcpkg install berkeleydb:x86-windows-static
- vcpkg install secp256k1:x86-windows-static
- vcpkg install leveldb:x86-windows-static
- git clone https://github.com/bitcoin/bitcoin.git
- git checkout -b testbuild
- git pull origin pull/11526/head # Visual Studio build configuration for Bitcoin Core
- ~~git pull origin pull/11558/head # Minimal code changes to allow msvc compilation~~
- ~~git pull origin pull/11562/head # bench: use std::chrono rather than gettimeofday~~
- ~~Copy and unzip attached bitcoin-config.h to src/config, edit as required [bitcoin-config.zip](https://github.com/bitcoin/bitcoin/files/1429484/bitcoin-config.zip)~~
- ~~git pull origin pull/13031/head # gmtime fix for msvc~~
- Build the Visual Studio solution which, if successful, will result in all but the Qt dependent libraries/programs being built. If the build fails please add a comment.

68400d8b96 tests: Use explicit imports (practicalswift)
Pull request description:
Enable automatic detection of undefined names in Python tests scripts. Remove wildcard imports.
Wildcard imports make it unclear which names are present in the namespace, confusing both readers and many automated tools.
An additional benefit of not using wildcard imports in tests scripts is that readers of a test script then can infer the rough testing scope just by looking at the imports.

4b7091a842 Replace median fee rate with feerate percentiles (Marcin Jachymiak)
Pull request description:
Currently, the `medianfeerate` statistic is calculated from the feerate of the middle transaction of a list of transactions sorted by feerate.
This PR instead uses the value of the 50th percentile weight unit in the block, and also calculates the feerate at the 10th, 25th, 75th, and 90th percentiles. This more accurately corresponds with what is generally meant by median feerate.

e306be7429 Use 72 byte dummy signatures when watching only inputs may be used (Andrew Chow)
48b1473c89 Use 71 byte signature for DUMMY_SIGNATURE_CREATOR (Andrew Chow)
18dfea0dd0 Always create 70 byte signatures with low R values (Andrew Chow)
Pull request description:
When creating signatures for transactions, always make one which has a 32 byte or smaller R and 32 byte or smaller S value. This results in signatures that are always less than 71 bytes (32 byte R + 32 byte S + 6 bytes DER + 1 byte sighash) with low R values. In most cases, the signature will be 71 bytes.
Because R is not mutable in the same way that S is, a low R value can only be found by trying different nonces. RFC 6979 for deterministic nonce generation has the option to specify additional entropy, so we simply use that and add a uin32_t counter which we increment in order to try different nonces. Nonces are sill deterministically generated as the nonce used will the be the first one where the counter results in a nonce that results in a low R value. Because different nonces need to be tried, time to produce a signature does increase. On average, it takes twice as long to make a signature as two signatures need to be created, on average, to find one with a low R.
Having a fixed size signature makes size calculations easier and also saves half a byte of transaction size, on average.
DUMMY_SIGNATURE_CREATOR has been modified to produce 71 byte dummy signatures instead of 72 byte signatures.

18f690ec2f wallet: shuffle coins before grouping, where warranted (Karl-Johan Alm)
Pull request description:
Coins are randomly shuffled in coin selection to avoid unintentional privacy leaks regarding the user's coin set. For the case where a user has a lot of coins with the same destination, these will be grouped into groups of 10 *before* the shuffling.
It is unclear whether this has any implications at all, but this PR plugs the potential issue, if there ever is one, by shuffling the coins before they are grouped.

The `help2man` parses a string containing two spaces between words with an issue:
it gives out `.TP` and `.IP` commands instead of a single `.IP` command.
Removing an extra space fixes this issue.
Currently the `-help` output for the `-stdin` option looks without any issue due to eliminating
of two spaces between words by a `FormatParagraph` call for this particular case.
For consistency and preventing from future regressions extra spaces have been removed from the both lines.
The redundant `strprintf` call has been removed aswell.
Make sure that translations are synchronized with transifex before the
branch-off point to minimize the difference and prevent duplicate work.

fada8966c5 qa: Close stdout and stderr file when node stops (MarcoFalke)
Pull request description:
### qa: Close stdout and stderr file when node stops
Since these files are potentially deleted by the test framework for cleanup, they should be closed first. Otherwise this will lead to errors on Windows when the tests finish successfully.
Side note: After the patch, it is no longer possible to reopen the file on Windows (see https://docs.python.org/3/library/tempfile.html#tempfile.NamedTemporaryFile)
### qa: Run gen_rpcauth with sys.executable
Similar to `test_runner.py`, the `sys.executable` needs to be passed down into subprocesses to pass on native Windows. (Should have no effect on Linux)
### qa: Use files for stdout/stderr to support Windows
It seems that using PIPE is not supported on Windows. Also, it is easier to just use the files that capture the stdout and stderr within the test node class.

1f87c372b5 Simplify comparison in rpc_blockchain.py. (Daniel Kraft)
Pull request description:
The test for `gettxoutsetinfo` in `rpc_blockchain.py` verifies that the result is the same as before after invalidating and reconsidering a block. The comparison has to exclude the `disk_size` field, though, as it is not deterministic.
Instead of comparing all the other fields for equality, this change explicitly removes the `disk_size` field and then compares the full objects. This makes the intent more explicit (compare everything except for `disk_size`, not compare just a given list of fields) and also the code simpler.
