e4f4ea47ebf7774fb6f445adde7bf7ea71fa05a1 lint: Catch use of [] or {} as default parameter values in Python functions (practicalswift)
25dd86715039586d92176eee16e9c6644d2547f0 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 :-)

* tests: move `move_to_next_cycle` to `DashTestFramework`
* tests: set correct defaults for `mine_cycle_quorum`
* tests: use correct quorum type in `create_islock`
* tests: fix `rpc_verifyislock.py`
* tests: fix `feature_llmq_is_cl_conflicts.py`
* tests: isolate zmq subscribers in `interface_zmq_dash.py`
this lets us call `test_*_publishers()` in any order and any number of times
* tests: check zmq for both deterministic and non-deterministic islocks
* instantsend: Avoid writing IS locks for unknown txes
* instantsend: Allow a competing tx into mempool if there is an islock waiting for it
* use try_emplace
* Hold cs_main while calling ResetBlockFailureFlags
When receiving an islock, propagate it as islock.
When creating/receiving and isdlock, propagate it as isdlock to peers which support it and as islock to peers which don't.
Functional tests to cover both islock and isdlock scenarios.
68400d8b96 tests: Use explicit imports (practicalswift)
Pull request description:
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.
An additional benefit of not using wildcard imports in tests scripts is that readers of a test script then can infer the rough testing scope just by looking at the imports.

Pull request description:
Splitting #11774 into two parts -- this part updates the README with the proposed naming convention, and adds some checks to test_runner.py that the number of tests violating the naming convention doesn't increase too much. Idea is this part of the change should not introduce merge conflicts or require much rebasing, so reviews of the complicated bits won't become invalidated too often; while the second part will just be file renames, which will require regular rebasing and will introduce merge conflicts with pending PRs, but can be merged later, and should also be much easier to review, since it will only include relatively trivial changes.

Pull request description:
This PR changes the functional tests to have a consistent naming scheme:
tests for individual RPC methods are named rpc_...
tests for interfaces (REST, ZMQ, RPC features) are named interface_...
tests that explicitly test the p2p interface are named p2p_...
tests for wallet features are named wallet_...
tests for mining features are named mining_...
tests for mempool behaviour are named mempool_...
tests for full features that aren't wallet/mining/mempool are named feature_...
Rationale: it's sometimes difficult for new contributors to know what's already covered by existing tests and where new tests should be added. Naming in a consistent fashion makes it easier to see what's already covered at a glance.
