-Waiting is important to avoid race conditions,
especially if testing peer info through rpc later.
-Wait for mininodes to be disconnected only, even
though it's more complex, because we may still want
to be connected to test nodes.
-Use peer to refer to mininodes instead of node
because they are not bitcoind nodes.
-Use log.debug for logs that give helpful but
not super necessary information.
-Adhere to style guidelines (newlines, capitalization).
16d4b3fd6d test: mempool.dat compatibility between versions (Ivan Metlushko)
Pull request description:
Rationale: Verify mempool.dat compatibility between versions
The format of mempool.dat has been changed in #18038
The tests verifies the fix made in #18807 and ensures that the file format is compatible between current version and v0.19.1
The test verifies both backward and forward compatibility.
This PR also adds a log when we fail to add a tx loaded from mempool.dat.
It was useful when debugging this test and could be potentially useful to debug other scenarios as well.
Closes#19037

ff8c430c65 [test] test disconnect for filterclear (gzhao408)
1c6b787e03 [netprocessing] disconnect node that sends filterclear (gzhao408)
Pull request description:
Nodes that don't have bloomfilters turned on (i.e. no `NODE_BLOOM` service) should disconnect peers that send them `filterclear` P2P messages.
Non-bloomfilter nodes already disconnect peers for [`filteradd` and `filterload`](19e919217e/src/net_processing.cpp (L2218)), but #8709 removed `filterclear` so it could be used to reset tx relay. This isn't needed now because using `feefilter` message is much better for this purpose (See #19204).
Also refactors existing disconnect logic for `filteradd` and `filterload` into respective message handlers and removes banning for them.

Pull request description:
This PR touches only the p2p_invalid_messages.py functional test module. There are two main goals accomplished here. First, it fixes the "invalid message size" test, which previously made a message that was invalid for multiple reasons. Second, it refactors the file into a single consistent style. This file appears to have originally had two authors, with different styles and some test duplication.
It should now be easier and quicker to understand this module, anticipating the upcoming [BIP324](https://github.com/bitcoin/bitcoin/pull/18242) and [AltNet](https://github.com/bitcoin/bitcoin/issues/18989) changes.
This should probably go in ahead of #19107, but the two are not strictly related.

The functional test covers eviction protection for peers that have sent us blocks or txns recently, or that have faster pings. I couldn't find a way to test the logic of `CConnman::AttemptToEvictConnection` that is based on netgroup (see #14210 for related discussion)

This PR adds a few tests that are bloomfilter-related, including behavior for when bloomfilters are turned _off_:
1. Tests p2p message `msg_mempool`: a node that has `peerbloomfilters` enabled should send its mempool (disabled behavior already tested [here](https://github.com/bitcoin/bitcoin/blob/master/test/functional/p2p_mempool.py)).
2. Tests that bloomfilter peers with [`fRelay=False`](https://github.com/bitcoin/bips/blob/master/bip-0037.mediawiki#extensions-to-existing-messages) in the `version` message should not receive any invs until they set the filter. The rest is the same as what’s already tested in `p2p_filter.py`.
3. Tests that peers get disconnected if they send `filterload` or `filteradd` p2p messages to a node with bloom filters disabled.
4. Refactor: renames p2p_mempool.py to p2p_nobloomfilter_messages.py.
5. Fixes race conditions in p2p_filter.py

34645c4dd0 Test txinwitness is accessible on coinbase vin (Rod Vagg)
3e4421070a Expose txinwitness for coinbase in JSON form (Rod Vagg)
Pull request description:
## Rationale
The CLI can provide you with everything about transactions and blocks that you need to reconstruct the block structure and raw block itself **except** for the witness commitment nonce which is stored in the `scriptWitness` of the coinbase and is not printed. You could manually parse the raw `"hex"` fields for transactions if you really wanted to, but this seems to defeat the point of having a JSONification of the raw block/transaction data.
Without the nonce you can't:
1. calculate and validate the witness commitment yourself, you can generate the witness tx merkle root but you don't have the nonce to combine it with
2. reconstruct the raw block form because you don't have `scriptWitness` stack associated with the coinbase (although you know how big it will be and can guess the common case of `[0x000...000]`)
I'm building some archiving tooling for block data and being able to do a validated two-way conversion is very helpful.
## What
This PR simply makes the `txinwitness` field not dependent on whether we are working with the coinbase or not. So you get it for the coinbase as well as the rest.
## Examples
Common case of a `[0x000...000]` nonce: 00000000000000000000140a7289f3aada855dfd23b0bb13bb5502b0ca60cdd7

],

}
],
...
```
## Alternatives
This field could be renamed for the coinbase, `"witnessnonce"` perhaps. It could also be omitted when null/zero (`0x000...000`).
## Tests
This didn't break any tests and I couldn't find an obvious way to include a test for this. If this is desired I'd apreicate some pointers.

This is a simple refactor of the specified test. It is now brought in
line with the rest of the tests in the module. This should make things
easier to debug, as all of the tests are now grouped together at the
top.
This test originally made a message with an invalid stated length, and
an invalid checksum. This was because only the header was changed, but
the checksum stayed the same. This was fine for now because we check
the header first to see if it has a valid stated size, and we disconnect
if it does not, so we never end up checking for the checksum. If this
behavior was to change, this test would become a problem. (Indeed I
discovered this when playing around with this behavior). By instead
creating a message with an oversized payload from the start, we create a
message with an invalid stated length but a valid checksum, as intended.
Additionally, this takes advantage to the newly module-global
VALID_DATA_LIMIT as opposed to the magic 0x02000000. Yes, 4MB < 32MiB,
but at the moment when receiving a message we check both, so this makes
the test tighter.
As well, this renames those variables to match PEP8 and this clears up
the comment relating to VALID_DATA_LIMIT.
Admittedly, this commit is mainly to make the following ones cleaner.
Test 1 is a duplicate of test_size() later in the file. Inexplicably,
this test does not work on macOS, whereas test_size() does.
Test 2 is problematic for two reasons. First, it always fails with an
invalid checksum, which is probably not what was intended. Second, it's
not defined at this layer what the behavior should be. Hypothetically,
if this test was fixed so that it gave messages with valid checksums,
then the message would pass successfully thought the network layer and
fail only in the processing layer. A priori the network layer has no
idea what the size of a message "actually" is.
The "Why does behavior change at 78 bytes" is because of the following:
print(len(node.p2p.build_message(msg))) # 125
=> Payload size = 125 - 24 = 101
If we take 77 bytes, then there are 101 - 77 = 24 left
That's exactly the size of a header
So, bitcoind deserializes the header and rejects it for some other reason
(Almost always an invalid size (too large))
But, if we take 78 bytes, then there are 101 - 78 = 23 left
That's not enough to fill a header, so the socket stays open waiting for
more data. That's why we sometimes have to push additional data in
order for the peer to disconnect.
Additionally, both of these tests use the "conn" variable. For fun, go
look at where it's declared. (Hint: test_large_inv(). Don't we all
love python's idea of scope?)

d15db4b1fc refactor: Fix unreachable code in init arg checks (Jonathan Schoeller)
Pull request description:
Closes: #19017
In #19015 it's been suggested that we add some new compiler warnings to our build. Some of these, such as `-Wunreachable-code-loop-increment`, generate warnings. We'll likely want to fix these up if we're going to turn these warnings on.
```shell
init.cpp:969:5: warning: loop will run at most once (loop increment never executed) [-Wunreachable-code-loop-increment]
for (const auto& arg : gArgs.GetUnsuitableSectionOnlyArgs()) {

1 warning generated.
```
aa8d76806c/src/init.cpp (L968-L972)
To fix this, collect all errors, and output them in a single error message after the loop completes. This resolves the unreachable code warning, and avoids popup hell that could result from outputting a seperate message for each error or warning one by one.

bd7e530f01 This PR adds initial support for type hints checking in python scripts. (Kiminuo)
Pull request description:
This PR adds initial support for type hints checking in python scripts.
Support for type hints was introduced in Python 3.5. Type hints make it easier to read and review code in my opinion. Also an IDE may discover a potential bug sooner. Yet, as PEP 484 says: "It should also be emphasized that Python will remain a dynamically typed language, and the authors have no desire to ever make type hints mandatory, even by convention."
[Mypy](https://mypy.readthedocs.io/en/latest/index.html) is used in `lint-python.sh` to do the type checking. The package is standard so there is little chance that it will be abandoned. Mypy checks that type hints in source code are correct when they are not, it fails with an error.
**Notes:**
* [--ignore-missing-imports](https://mypy.readthedocs.io/en/latest/command_line.html#cmdoption-mypy-ignore-missing-imports) switch is passed on to `mypy` checker for now. The effect of this is that one does not need `# type: ignore` for `import zmq`. More information about import processing can be found [here](https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports). This can be changed in a follow-up PR, if it is deemed useful.
* We are stuck with Python 3.5 until 04/2021 (see https://packages.ubuntu.com/xenial/python3). When Python version is bumped to 3.6+, one can change:
```python
_opcode_instances = [] # type: List[CScriptOp]
```
to
```python
_opcode_instances:List[CScriptOp] = []
```
for type hints that are **not** function parameters and function return types.
**Useful resources:**

Unlike that PR, which implements some new behavior, this just restores previous wallet notification and status behavior for transactions removed from the mempool because they conflict with transactions in a block. The behavior was accidentally changed in two `CWallet::BlockConnected` updates: a31be09bfd and 7e89994133 from https://github.com/bitcoin/bitcoin/pull/16624, causing issue https://github.com/bitcoin/bitcoin/issues/18325.
The change here could be improved and replaced with a more comprehensive cleanup, so it includes a detailed comment explaining future considerations.

Support for type hints was introduced in Python 3.5. Type hints make it easier to read and review code in my opinion. Also an IDE may discover a potential bug sooner. Yet, as PEP 484 says: "It should also be emphasized that Python will remain a dynamically typed language, and the authors have no desire to ever make type hints mandatory, even by convention."
Mypy is used in lint-python.sh to do the type checking. The package is standard so there is little chance that it will be abandoned. Mypy checks that type hints in source code are correct when they are not, it fails with an error.

Building with -Wunreachable-code-loop-increment causes a warning
due to always returning on the first iteration of the loop that
outputs errors on invalid args.
Collect all errors, and output them in a single error message
after the loop completes, resolving the warning and avoiding
popup hell by outputting a seperate message for each error.
