333317ce6b test: Test that low difficulty chain fork is rejected (MarcoFalke)
fa31dc1bf4 test: Pass down correct chain name in tests (MarcoFalke)
Pull request description:
To prevent OOM, Bitcoin Core will reject chain forks at low difficulty by default. This is the only use-case of checkpoints, so add a test for it to make sure the feature works as expected. If it didn't work, checkpoints would have no use-case and we might as well remove them

ec4c79326b signrawtransaction*: improve error for partial signing (Anthony Towns)
3c481f8921 signrawtransactionwithkey: better error messages for bad redeemScript/witnessScript (Anthony Towns)
Pull request description:
Two fixes for `signrawtransactionwith{key,wallet}` (in addition to #16250): one that checks redeemScript/witnessScript matches scriptPubKey (and if both are provided that they match each other sanely), and the other changes the warning when some-but-not-all the signatures for a CHECKMULTISIG are provided to something that suggests more signatures may be all that's required.

Pull request description:
The new response keys `height` and `bestblock` allow the client to know at what point the scan took place.
The help message now has all the response keys (`result` and `txouts` were missing) and it's improved a bit. Note that `searched_items` key is renamed to `txouts`, considering `scantxoutset` is marked experimental.

Pull request description:
Transaction relay is optimized for a combination of redundancy/robustness as well as bandwidth minimization -- as a result transaction relay leaks information that adversaries can use to infer the network topology.
Network topology is better kept private for (at least) two reasons:
(a) Knowledge of the network graph can make it easier to find the source IP of a given transaction.
(b) Knowledge of the network graph could be used to split a target node or nodes from the honest network (eg by knowing which peers to attack in order to achieve a network split).
We can eliminate the risks of (b) by separating block relay from transaction relay; inferring network connectivity from the relay of blocks/block headers is much more expensive for an adversary.
After this commit, bitcoind will make 2 additional outbound connections that are only used for block relay. (In the future, we might consider rotating our transaction-relay peers to help limit the effects of (a).)

5ce822efbe Conservatively accept RBF bumps bumping one tx at the package limits (Matt Corallo)
Pull request description:
Based on #15681, this adds support for some simple cases of RBF inside of large packages. Issue pointed out by sdaftuar in #15681, and this fix (or a broader one) is required ot make #15681 fully useful.
Accept RBF bumps of single transactions (ie which evict exactly one
transaction) even when that transaction is a member of a package
which is currently at the package limit iff the new transaction
does not add any additional mempool dependencies from the original.
This could be made a bit looser in the future and still be safe,

a31be09bfd Encapsulate tx status in a Confirmation struct (Antoine Riard)
Pull request description:
While working on #15931, I've tried to rationalize tx state management to ease integration of block height tracking per-wallet tx. We currently rely on a combination of `hashBlock` and `nIndex` with magic value to determine tx confirmation, conflicted or abandoned state. It's hard to reason and error-prone. To solve that, we encapsulate these fields in a `TxConfirmation` struct and introduce a `TxState` member that we update accordingly at block connection/disconnection.
Following jnewbery [recommendation](https://github.com/bitcoin/bitcoin/pull/15931#discussion_r312576506), I've taken these changes in its own commit, and open a PR to get them first. It would ease review of aforementioned PR, but above all should ease fixing of long-term issues like :
* https://github.com/bitcoin/bitcoin/issues/7315 (but maybe we should abandon abandontransaction or relieve it to only free outpoints not track the transaction as abandoned in itself, need its own discussion)
* https://github.com/bitcoin/bitcoin/issues/8692 where we should cancel conflicted state of transactions chain smoothly
* `MarkConflicted` in `LoadToWallet` is likely useless if we track conflicts rights at block connection
Main changes of this PR to get right are tx update in `AddToWallet` and serialization/deserialization logic.

If we set fRelay=false in our VERSION message, and a peer sends an INV or TX
message anyway, disconnect. Since we use fRelay=false to minimize bandwidth,
we should not tolerate remaining connected to a peer violating the protocol.

d48c1e837a Add window final block height to getchaintxstats (Jonathan "Duke" Leto)
Pull request description:
This patch is motivated by the desire to make the output of `getchaintxstats` more useful and optimized for applications to consume and render the data.
Firstly, this data is already available to the RPC, no additional work is done. Currently additional RPC calls will be needed to look up the height of the final block in the window or the block height that began the window.
By adding the block height of the final block in the window, the JSON is "self-contained" and applications can calculate the exact block height range of the window with no additional RPC requests.
For example, a web application which wants to render historical information for `getchaintxstats` RPC on various window sizes might call the RPC with various window lengths, once per day, and store the JSON results somewhere. Because the final block height of each dataset is included, it's no extra work to determine the exact block window range of each JSON response.

e4f4ea47eb lint: Catch use of [] or {} as default parameter values in Python functions (practicalswift)
25dd867150 Avoid using mutable default parameter values (practicalswift)
Pull request description:
Avoid common Python default parameter gotcha when mutable `dict`/`list`:s are used as default parameter values.
Examples of this gotcha caught during review:
* https://github.com/bitcoin/bitcoin/pull/16673#discussion_r317415261
* https://github.com/bitcoin/bitcoin/pull/14565#discussion_r241942304
Perhaps surprisingly this is how mutable list and dictionary default parameter values behave in Python:
```
>>> def f(i, j=[], k={}):
... j.append(i)
... k[i] = True
... return j, k
...
>>> f(1)
([1], {1: True})
>>> f(1)
([1, 1], {1: True})
>>> f(2)
([1, 1, 2], {1: True, 2: True})
```
In contrast to:
```
>>> def f(i, j=None, k=None):
... if j is None:
... j = []
... if k is None:
... k = {}
... j.append(i)
... k[i] = True
... return j, k
...
>>> f(1)
([1], {1: True})
>>> f(1)
([1], {1: True})
>>> f(2)
([2], {2: True})
```
The latter is typically the intended behaviour.
This PR fixes two instances of this and adds a check guarding against this gotcha going forward :-)

6011c9d72d QA: fix rpc_setban.py race (Jonas Schnelli)
Pull request description:
The new `rpc_setban.py` test failes regularly on CIs due to a race between injecting the ban and testing the log "on the other side".
The problem is, that the test immediately after the `addnode` command on node0 checks for the `dropped (banned)` entry on node1 (without giving some time).
Adding a 2 seconds sleep seems to solve the race (I guess there is no better event-driven delay).

Pull request description:
Right now it's a bit annoying to deal with watchonly wallets, many rpc commands have an `include_watchonly` argument that needs to be explicitly set.
Wallets created with `createwallet` can have a `disable_private_keys` parameter, for those wallets we already know that they are watchonly, so there's no reason to have to explicitly ask for it for every command. Instead we check this wallet flag when the `include_watchonly` parameter isn't set.
