This causes re-tries of LLMQ connections, which is required in cases
where 2 MNs tried to connect to each other and due to bad timing then
disconnected each other.
This is especially important when waiting for phase 1 (initialization),
as we might have skipped a whole DKG session before while the async DKG
session handler is still in the init phase (but for the old/skipped LLMQ).
75d0e4c544 [qa] Delete cookie file before starting node (Suhas Daftuar)
Pull request description:
When a node is restarted during a test after an unclean shutdown (such
as with -dbcrashratio), it's possible an old cookie file was left
behind. This can cause a race condition when restarting the node, where
the test framework might try to connect using credentials from the
old cookie file, just as the node will generate new credentials and
overwrite the old file.
Delete any such cookie file if present prior to startup.

Pull request description:
When tests fail (such as due to a bug in the test, race condition, etc), it's possible that we could follow code paths that bypass our normal node shutdown that occurs in `TestNode.stop_node`. Add a destructor to `TestNode` that cleans this up.

ec527c6 Don't allow relative -walletdir paths (Russell Yanofsky)
Pull request description:
This makes it an error to explicitly specify a non-absolute -walletdir path, and also adds a debug.log warning if a relative rather than absolute -datadir path is configured.
Specifying paths relative to the current working directory in a daemon process can be dangerous, because files can fail to be located even if the configuration doesn't change, but the daemon is started up differently.
Specifying a relative -datadir now adds a warning to the debug log. It would not be backwards-compatible to forbid relative -datadir paths entirely, and it could also be inconvenient for command line testing.
Specifying a relative -walletdir now results in a startup error. But since the -walletdir option is new in 0.16.0, there should be no compatibility issues. Another reason not to use working directory paths for -walletdir specifically is that the default -walletdir is a "wallets" subdirectory inside the datadir, so it could be surprising that setting -walletdir manually would choose a directory rooted in a completely different location.

Pull request description:
Closes#11348
Adds a `-walletdir` parameter which specifies a directory to use for wallets, allowing them to be stored separately from the 'main' data directory. Creates a new `wallets/` directory in datadir if this is the first time running, and defaults to using it if it exists.
Includes tests and release notes. Things which might need to be considered more:
- there is no 'lock' on the wallets directory, which might be needed?
- because this uses a new wallets/ directory by default, downgrading to an earlier version won't see the wallets in that directory (not a big deal though, users can just copy them up to the main dir)
- jnewbery suggested putting each wallet in its own directory, which is a good idea, but out of scope for this PR IMO. EDIT: this is being done in https://github.com/bitcoin/bitcoin/pull/11687
- doc/files.md needs updating (will do soon)
I also considered including a cleanup by removing caching of data directory paths and instead just initialise them once on startup (c.f. #3073), but decided it wasn't super relevant here will just complicate review.

1817398b3 mininode: add an optimistic write and disable nagle (Cory Fields)
Pull request description:
Disclaimer: I'm not familiar with asyncore, so I'm unclear how safe this is. It works for me (tm).
Because the poll/select loop may pause for 100msec before actually doing a send, and we have no way to force the loop awake, try sending from the calling thread if the queue is empty.
Also, disable nagle as all sends should be either full messages or unfinished sends.
This shaves an average of ~1 minute or so off of my accumulated runtime, and 10-15 seconds off of actual runtime.

c1d742025c [tests] Fix feature_block flakiness (John Newbery)
Pull request description:
feature_block.py occasionally fails on Travis. I believe this is due to
a a race condition when reconnecting to bitcoind after a subtest that
expects disconnection. If the test runs ahead and sends the INV for the
subsequent test before we've received the initial sync getheaders, then
we may end up sending two headers messages - one as a response to the
initial sync getheaders and one in response to the INV getheaders. If
both of those headers fail validation with a DoS score of 50 or higher,
then we'll unexpectedly be disconnected.
There is only one validation failure that has a DoS score bewteen 50 and
100, which is high-hash. That's why the test is failing immediately
after the "Reject a block with invalid work" subtest.
Fix is to wait for the initial getheaders from the peer before we
start populating our blockstore. That way we won't have any invalid
headers to respond to it with.

- CBlock and friends are still in test_framework.mininode
- "-whitelist" causes connections to not be dropped, which in turn causes
sync_blocks with reconnect=True to fail
- "bad-cb-amount" does not cause a ban in Dash, so reconnect must be False
- Dash already bans when a header is received which is a child of an invalid
header, causing block requests to never happen

Pull request description:
Fixes#11777. Reverts #11006. Replaces #13501.
With this change the HTTP server will exit gracefully, meaning that all requests will finish processing and sending the response, even if this means to wait more than 2 seconds (current time allowed to exit the event loop).
Another small change is that connections are accepted even when the server is stopping, but HTTP requests are rejected. This can be improved later, especially if chunked replies are implemented.
Briefly, before this PR, this is the order or events when a request arrives (RPC `stop`):
1. `bufferevent_disable(..., EV_READ)`
2. `StartShutdown()`
3. `evhttp_del_accept_socket(...)`
4. `ThreadHTTP` terminates (event loop exits) because there are no active or pending events thanks to 1. and 3.
5. client doesn't get the response thanks to 4.
This can be verified by applying
```diff
// Event loop will exit after current HTTP requests have been handled, so
// this reply will get back to the client.
StartShutdown();
+ MilliSleep(2000);
return "Bitcoin server stopping";
}
```
and checking the log output:
```
Received a POST request for / from 127.0.0.1:62443
ThreadRPCServer method=stop user=__cookie__

... sleep 2 seconds ...
Waiting for HTTP event thread to exit

```
For this reason point 3. is moved right after all HTTP workers quit. In that moment HTTP replies are queued in the event loop which keeps spinning util all connections are closed. In order to trigger the server side close with keep alive connections (implicit in HTTP/1.1) the header `Connection: close` is sent if shutdown was requested. This can be tested by
```
bitcoind -regtest
nc localhost 18443
POST / HTTP/1.1
Authorization: Basic ...
Content-Type: application/json
Content-Length: 44
{"jsonrpc": "2.0","method":"stop","id":123}
```
Summing up, this PR:
- removes explicit event loop exit — event loop exits once there are no active or pending events
- changes the moment the listening sockets are removed — explained above
- sends header `Connection: close` on active requests when shutdown was requested which is relevant when it's a persistent connection (default in HTTP 1.1) — libevent is aware of this header and closes the connection gracefully
- removes event loop explicit break after 2 seconds timeout

* Use `force_finish_mnsync` from util.py in dip3-deterministicmns.py and drop local unused functions
Also move the call, `force_finish_mnsync` should be called before `connect_nodes_bi`
95e2e9a [tests] Change invalidtxrequest to use BitcoinTestFramework (John Newbery)

c32cf9f [tests] Add P2PDataStore class (John Newbery)
cc046f6 [tests] Reduce NodeConn connection logging from info to debug (John Newbery)
Pull request description:
Next step in #10603
- first commit changes log level for an internal log from INFO to DEBUG. (Not really related, but I started finding the INFO level logging annoying when debuging test failures)
- second commit introduces a `P2PStub` class - a subclass of `NodeConnCB` which has its own block and tx store and responds appropriately to getdata requests. Not all the functionality is used in `invalidtxrequest.py`, but will be used in `invalidblockrequest.py` and `p2p-fullblocktest` when those are changed to use `BitcoinTestFramework`
- third commit tidies up `invalidtxrequest.py`
- fourth commit removes usage of `ComparisonTestFramework`

faaa7db qa: Only allow disconnecting all NodeConns (MarcoFalke)
Pull request description:
Disconnecting the connection with `index=0` makes no sense when there are more than one connections, as the list "rotates around" and populates index 0 after `del`.
Just disconnect all NodeConns in any case.
