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 :-)

8a3b2eb175 move-only: move coins statistics utils out of RPC (James O'Beirne)
Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11):
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal
---
In the short-term, this move-only commit will help with fuzzing (https://github.com/bitcoin/bitcoin/pull/15606#issuecomment-524482297). Later, these procedures will be used to compute statistics (particularly a content hash) for UTXO sets coming in from snapshots.
Most easily reviewed with `git ... --color-moved=dimmed_zebra`. A nice follow-up would be adding unittests, which I'll do if nobody else gets around to it.

Pull request description:
Related to #16354.
This PR adds additional configure flags to packages in depends to explicitly disable features we aren't using; similar to #16183. It also fixes passing `--without-tools` to `qrencode`.
I've added `--disable-drafts` to `zeromq`:
```bash
Build and install draft classes and methods [default=yes]
```
I'm not entirely sure how far we want to take this. i.e in the `zeromq` package we explicitly pass `--without-libsodium`, even though it's disabled by default.
Do we also want to explicitly pass all the other `--without` flags? :
```bash
--with-libgssapi_krb5 require libzmq build with libgssapi_krb5
[default=no]
--with-libsodium use libsodium instead of built-in tweetnacl
[default=no]
--with-pgm build libzmq with PGM extension. Requires pkg-config
[default=no]
--with-norm build libzmq with NORM protocol extension,
optionally specifying norm path [default=no]
--with-vmci build libzmq with VMCI transport [default=no]
```

7e1634a927 Release notes: edit previously-detached notes (David A. Harding)
e7415a5a95 Doc: move detached release notes into release-notes.md (David A. Harding)
Pull request description:
Merges in detached release notes, edits each change down to a single paragraph bullet point (or, in a couple cases, two individual bullet points in separate sections each with a single paragraph). Adds notes for some undocumented changes I found reviewing `git log --merges`. Also tries something new: adds the PR number(s) after each entry to make it easier for both reviewers and end-user readers to look up the details behind each change. (If the PR numbers are unwanted, they're easy to remove either in this PR or later in the release process.)
I also checked the 0.18 branch but I didn't find anything in the current release notes that had been backported.
A particular focus in my editing was trying to keep things concise, particularly by pointing to RPC documentation when available (or upcoming, as in #16629). I do suspect that one downside of detached notes is that people write longer summaries than they would if they knew there were already 300 other lines of release notes. :-)
The first commit only moves notes, puts them in bullet form, adjusts indentation appropriately, and drops unneeded headers. It can be reviewed with `git diff --color-moved=dimmed-zebra` for a little bit of a speedup, but unfortunately I wasn't smart enough to split my copy/pasting and line wrapping into separate commits, so it's not a transparently move-only change.

a4765bd77f gui: Ensure tx send error highlight is visible (bpay)
Pull request description:
Rebased and squashed #14956.
> If sending to multiple recipients and one of the recipient fields is malformed, the highlighted field may not be visible due to being scrolled out of view. This results in a confusing lack of error feedback.
> Avoid this problem by ensuring the first field containing an error is scrolled into view when Send is clicked.
You can see the behavior here: https://imgur.com/a/QZG5TQc
How to test:
Add a few recipients and give any of them an invalid address or amount. Scroll the invalid recipient out of view and hit Send. With this change, the GUI will scroll to show the invalid recipient, with master it will not, "hiding" the error.

We shouldn't rely on this sync call to get an accurate view of txn
state, if a tx conflicts with one in mapTx we are going to update
our wallet dependencies in AddToWalletIfInvolvingMe while conflicting
txn get connected. If it doesn't conflict with one of our dependencies
we are not going to track it anyway.
This is a cleanup, as this SyncTransaction is redundant with the
following one for confirmation which is triggering the MarkConflicted
logic. We keep the loop because set of conflicted txn isn't same as txn
included in block.
Instead of relying on combination of hashBlock and nIndex
values to manage tx in its lifecycle, we introduce 4
status : CONFIRMED, UNCONFIRMED, CONFLICTED, ABANDONED.
hashBlock and nIndex magic values should only be used at
serialization/deserialization for backward-compatibility.
At block disconnection, we know flag txn as UNCONFIRMED where
previously they kept their states until being override by a
block connection or abandontransaction call. This is a change
in behavior for which user may have to call abandon twice
if transaction is disconnected and not accepted back in the mempool.
We assert status transitioning right in AddToWallet. Doing so
flagged a misbehavior in ComputeTimeSmart unit test where same
tx is confirmed twice in different block. To avoid inconsistencies
we unconfirmed tx before new connection in different block. We
also remove a cs_main lock in test, as AddToWallet and its
callees don't rely on locked chain.
In Qt 5.12 and before the QFontMetrics::width() is used and it is
deprecated since Qt 13.0.
In Qt 5.11 the QFontMetrics::horizontalAdvance() was introduced.
If sending to multiple recipients and one of the recipient fields is malformed,
the highlighted field may not be visible due to being scrolled out of view,
leading to a confusing lack of error feedback when clicking Send. To avoid this
problem ensure the first field containing an error is scrolled into view
when Send is clicked.

There seems to be some confusion about exactly how to use depends, when to pass a prefix to `./configure` etc (see #16367, #16654).
I've cherry-picked two of russ's commits out of #16367, as they are clear stand-alone improvements and we don't have to wait for #16367 to improve the depends documentation.
