50cede3f5a4d4fbfbb7c420b94e661a6a159bced [mempool] Allow one extra single-ancestor transaction per package (Matt Corallo)
Pull request description:
This implements the proposed policy change from [1], which allows
certain classes of contract protocols involving revocation
punishments to use CPFP. Note that some such use-cases may still
want some form of one-deep package relay, though even this alone
may greatly simplify some lightning fee negotiation.

fa69588537bc91c0aedbc89ef1760d89cbffad75 test: Make PORT_MIN in test runner configurable (MarcoFalke)
Pull request description:
This is needed when some ports in the port range are used by other processes. Note that simply assigning the ports dynamically does not work:
* We spin up several nodes per test (each node gets its own port)
* We run several tests in parallel
So to avoid nodes from different tests colliding on ports, the port assignment must be deterministic (can not be dynamic).

1111bb91f517838e5b9f778bf6b5a9c8d561e857 test: Reformat python imports to aid scripted diff (MarcoFalke)
Pull request description:
By default all test nodes are connected in a chain. However, instead of just a single connection between each pair of nodes, we end up with up to four connections for a "middle" node (two outbound, two inbound, from each side).
This is generally redundant (tx and block relay should succeed with just a single connection) and confusing. For example, test timeouts after a call to `sync_` may be racy and hard to reproduce. On top of that, the test `debug.log`s are hard to read because txs and block invs may be relayed on the same connection multiple times.
Fix this by inlining `connect_nodes_bi` in the two tests that need it, and then replace it with a single `connect_nodes` in all other tests.
Historic background:
`connect_nodes_bi` has been introduced as a (temporary?) workaround for bug #5113 and #5138, which has long been fixed in #5157 and #5662.

Pull request description:
This functional test includes two scenarios that test for regressions of vulnerabilities, but they are only briefly described. There are freely available documents explaining in detail the issues, but without explicit mentions, the developer trying to maintain the code needs an additional step of digging in commit history and PR conversations to figure it out.
Added comments to explicitly mention CVE-2018-17144 and CVE-2012-2459, for more complete documentation.
This improves developer experience by making understanding the tests easier.

`connect_nodes_bi` has been introduced as a (temporary?) workaround for bug #5113 and #5138, which has long been fixed in #5157 and #5662.
Thus remove the `connect_nodes_bi` workaround from the rpc_invalidateblock test.

1eb13f09a9d8c2c7dc69f4cdf1b1ccf632543aa0 test: Add log messages to test/functional/tool_wallet.py (Jon Atack)
Pull request description:
This pull request adds test coverage in `test/functional/tool_wallet.py` to reproduce unexpected writes to the wallet as described in https://github.com/bitcoin/bitcoin/issues/15608 and serve as a benchmark for fixing the issue:
- Wallet tool `info` unexpectedly writes to the wallet file if the wallet file permissions are read/write.
- Wallet tool `info` raises with "Error loading . Is wallet being used by another process?" if the wallet file permissions are read-only.
Goals:
1. Reproduce the reported issue, define the current unexpected behavior, and add test coverage to guide a future fix. Add debug-level logging for sanity checking and commented-out assertions to be uncommented when fixing the issue. Add the same coverage to the wallet tool create test and the getwalletinfo test as regression tests while fixing the issue.
2. Add info log messages as there are currently none in the test file.
3. Split the tests out to separate functions as per review feedback.
Thanks to Marco Falke for pointing me in the right direction.

faa1e0fb1712b1f94334e42794163f79988270fd qt: test: Create at most one testing setup (MarcoFalke)
Pull request description:
It is assumed that ideally only one BasicTestingSetup exists at any point in time for each process (due to use of globals).
This assumption is violated in the GUI tests, as a testing setup is created as the first step of the `main` function and then (sometimes) another one for the following test cases.
So, the gui tests create two testing setups:
* `BasicTestingSetup` in `main` (added in fa4a04a5a942d582c62773d815c7e1e9897975d0)
* a testing setup for individual test cases
Avoid that by destructing the testing setup in main after creation and then move the explicit `ECC_Stop` to the only places where it is needed (before and after `apptests`).

Instead of them the gitian descriptors use a git tag (if available) or a commit hash.

Pull request description:
This introduces a consistent notation for RPC arguments in `scantxoutset`, `importmulti`, and `deriveaddresses`, either:
* `"range" : int` to just specify the end of the range
* `"range" : [int,int]` to specify both the begin and the end of the range.
For `scantxoutset`, this is a backward compatible new feature. For the two other RPCs, it's an incompatible change, but neither of them has been in a release so far. Because of that non-released reason, this only makes sense in 0.18, in my opinion.
I suggest this as an alternative to #15496, which only makes `deriveaddresses` compatible with `importmulti`, but not with the existing `scantxoutset` RPC. I also think `[int,int]` is more convenient than `{"start":int,"stop":int}`.
I realize this is technically a feature added to `scantxoutset` after the feature freeze. If desired, I'll drop the `scantxoutset` changes.

We can not add a test that a later duplicate tx overwrites a previous one, because BIP30 is always enforced on regtest. If someone feels strongly about such a test, some Bitcoin Core code would have to be modified, which can be done in a follow up pull request.
Also, add a commit to fix the BIP34 test failures reported in https://github.com/bitcoin/bitcoin/pull/14633#issue-227712540

The `walletcreatefundedpsbt` RPC call currently ignores `-walletrbf` and defaults to not use RBF. This PR fixes that.
This PR also replaces UniValue in `ConstructTransaction` with a `bool` in preparation of moving this helper method out of the RPC codebase entirely. This may be a bit overkill, but does slightly simplify it.

fae91a09c453a9a95c382df765bd71e54698d5b2 test: Remove incorrect and unused try-block in assert_debug_log (MarcoFalke)
Pull request description:
This try block has accidentally been added by me in fa3e9f7627784ee00980590e5bf044a0e1249999.
It was unused all the time, but commit 6011c9d72d1df5c2cd09de6f85c21eb4f7eb1ba8 added a `return` in the finally block, muting all exceptions.
This can be tested by adding an `assert False` after any `with ...assert_debug_log...:` line.

utACK fae91a09c453a9a95c382df765bd71e54698d5b2. I didn't know returning inside a `finally` block would cancel pending exceptions or return values, but I guess this makes sense and is a good thing to be aware of.

6011c9d72d1df5c2cd09de6f85c21eb4f7eb1ba8 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).
Example of a failed test: https://bitcoinbuilds.org/index.php?ansilog=bf743910-103f-4b54-9a97-960c471061bd.log#l2906

c4606b84329d760d7cee144bebe05807857edaae Add Travis check for single parameter constructors not marked "explicit" (practicalswift)
Pull request description:
Make single parameter constructors `explicit` (C++11).
Rationale from the developer notes:
> - By default, declare single-argument constructors `explicit`.
> - *Rationale*: This is a precaution to avoid unintended conversions that might
> arise when single-argument constructors are used as implicit conversion
> functions.

9f9db39041 QA/mininode: Send all headers upfront in send_blocks_and_test to avoid sending an unconnected one (Luke Dashjr)
Pull request description:
While this doesn't currently trigger any problems, the network protocol does expect headers to be sent connectable in normal circumstances, and if too many are sent out of order will disconnect the peer.

f402012cc fixup: Fix prunning test (João Barbosa)
97f517dd8 Fix RPC/pruneblockchain returned prune height (Jonas Schnelli)
Pull request description:
The help of `pruneblockchain` tells us that the return value is `Height of the last block pruned.`,... but the implementation naively returns the provided input `height` and therefore not respecting that pruning can't be done on all possible blockheight due to the fact that we only prune complete blockfiles (which combine multiple blocks).
This fixes the return value to actually return the correct prune height.
