661ac15a4a appveyor: Run functional tests on appveyor (Chun Kuan Lee)
2148c36b6e tests: Make it possible to run functional tests on Windows (Chun Kuan Lee)
Pull request description:
This PR do the following things:
- Make functional tests compatible with Windows
- Print color output in functional tests for Windows 10
- Run util and functional tests on appveyor
- Do not run symlink tests on Windows
Note:
- The wallet_multiwallet.py fail is unrelated to the test framework, it's a bug related to c++ code or maybe dependencies. `bitcoind` would exit with 0xC0000005(Access violation) during shutdown occasionally. Disable this for now.
- Not using `--failfast` because this is still in experimental. We should track if there is any other error.
- Disable ZMQ tests because the python zmq library could cause access violation sometimes.
- Disable `feature_notifications` because Bitcoin Core handles the command in different thread, whicha can cause a race condition.

5eb20f81d9 Consistently use ParseHashV to validate hash inputs in rpc (Ben Woosley)
Pull request description:
ParseHashV validates the length and encoding of the string and throws
an informative RPC error on failure, which is as good or better than
these alternative calls.
Note I switched ParseHashV to check string length first, because
IsHex tests that the length is even, and an error like:
"must be of length 64 (not 63, for X)" is much more informative than
"must be hexadecimal string (not X)" in that case.

a2eb6f5405 [rpc] Add getnodeaddresses RPC command (chris-belcher)
Pull request description:
Implements issue https://github.com/bitcoin/bitcoin/issues/9463
New getnodeaddresses call gives access via RPC to the peers known by the node. It may be useful for bitcoin wallets to broadcast their transactions over tor for improved privacy without using the centralized DNS seeds. getnodeaddresses is very similar to the getaddr p2p method.
Please advise me on the best approach for writing an automated test. By my reading the getaddr p2p method also isn't really tested.

Pull request description:
This is the replacement for #11678 which implements @ryanofsky's [suggestion](https://github.com/bitcoin/bitcoin/pull/11678#pullrequestreview-76464511).
Shutting down the software was to prevent the BDB environment from writing unencrypted private keys to disk in the database log files, as was noted [here](https://bitcointalk.org/index.php?topic=51474.msg616068#msg616068). This PR replaces the shutdown behavior with a CDBEnv flush, close, and reopen which achieves the same effect: everything is cleanly flushed and closed, the log files are removed, and then the environment reopened to continue normal operation.
To ensure that no unencrypted private keys are in the log files after encrypting the wallet, I wrote [this script](https://gist.github.com/achow101/7f7143e6c3d3fdc034d3470e72823e9d) to pull private keys from the original wallet file and searches for these keys in the log files (note that you will have to change your file paths to make it work on your own machine).
As for concerns about private keys being written to slack space or being kept in memory, these behaviors no longer exist after the original wallet encryption PR and the shutting down solution from 2011.

Pull request description:
Currently the functional tests require the wallet module to be compiled into the Bitcoin Core executable. For example the premine (or datadir cache) to speed up tests when run in parallel would mine a bunch of blocks and store the private keys to sign the coinbase tx outputs in a wallet. There is no need to have the overhead of the whole wallet module by using keys that are deterministic for all runs.
Note that this change most likely requires the `./test/cache/` to be cleared.

fa6ab8ada1 rpc: Return more specific reject reason for submitblock (MarcoFalke)
Pull request description:
The second commit in #13439 made the `TODO` in the first commit impossible to solve.
The meaning of `fNewBlock` changed from "This is the first time we process this block" to "We are about to write the new *valid* block".
So whenever `fNewBlock` is true, the block was valid. And whenever the `fNewBlock` is false, the block is either valid or invalid. If it was valid and not new, we know it is a `"duplicate"`. In all other cases, the `BIP22ValidationResult()` will return the reason why it is invalid.

870bd4c73d Update functional RBF test to check replaceable flag (dexX7)
820d31f95f Add "bip125-replaceable" flag to mempool RPCs (dexX7)
Pull request description:
This pull request adds a flag "bip125-replaceable" to the mempool RPCs getrawmempool, getmempoolentry, getmempoolancestors and getmempooldescendants, which indicates whether an unconfirmed transaction might be replaced.
Initially the flag was added to the raw transaction RPCs, but thanks to @conscott, it was moved to the mempool RPCs, which actually have access to the mempool.
~~This pull request adds a flag "bip125-replaceable" to the RPCs "getrawtransaction" and "decoderawtransaction", which indicates, whether a transaction signals BIP 125 replaceability.~~
There was some discussion in #7817, whether showing replaceability in the UI could lead to the false assumption that transactions that don't signal BIP 125 are truely non-replaceable, but given that this PR tackles the raw transaction interface, which is a rather low level tool, I believe having this extra piece of information isn't bad.

68400d8b96 tests: Use explicit imports (practicalswift)

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.

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.

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.

When extra entropy is not specified by the caller, CKey::Sign will
now always create a signature that has a low R value and is at most
70 bytes. The resulting signature on the stack will be 71 bytes when
the sighash byte is included.
Using low R signatures means that the resulting DER encoded signature
will never need to have additional padding to account for high R
values.
