b658d7d5c5 test: update assert_fee_amount() in test_framework/util.py (Jon Atack)
Pull request description:
Follow-up to 42e1b5d979 (#12486).
- update call to `round()` with our utility function `satoshi_round()` to avoid intermittent test failures
- rename `fee_per_kB` to `feerate_BTC_kvB` for precision
- store division result in `feerate_BTC_vB`
Possibly resolves#19418.

0ab4c3b272 Return false on corrupt tx rather than asserting (Samuel Dobson)
Pull request description:
Takes up #19793
Rather than asserting, we log an error and return CORRUPT so that the user is informed. This type of error isn't critical so it isn't worth `assert`ing.

0dc8bf5b92 [net processing] Dont request compact blocks in blocks-only mode (Niklas Gögge)
Pull request description:
A blocks-only node does not participate in transaction relay to reduce its own bandwidth usage and therefore does not have a mempool. The use of compact blocks is not beneficial to such a node since it will always have to download full blocks.
In both high- and low-bandwidth relaying the `cmpctblock` message is sent. This represent a bandwidth overhead for blocks-only nodes because the `cmpctblock` message is several times larger in the average case than the equivalent `headers` or `inv` announcement.
>**Example:**
>A block with 2000 txs results in a `cmpctblock` with 2000*6 bytes in short ids. This is several times larger than the equivalent 82 bytes for a `headers` message or 37 bytes for an `inv`.
## Approach
This PR makes blocks-only nodes always use the legacy relaying to download new blocks.
It does so by making blocks-only nodes never initiate a high-bandwidth block relay connection by disabling the sending of `sendcmpct(1)`. Additionally a blocks-only node will never request a compact block using `getdata(CMPCT)`.
A blocks-only node will continue to serve compact blocks to its peers in both high- and low-bandwidth mode.

4446ef0a54 build: remove support for weak linking getauxval() (fanquake)
e56100c5b4 build: remove arm includes from getauxval() check (fanquake)
Pull request description:
It was [pointed out in #23030](https://github.com/bitcoin/bitcoin/pull/23030#issuecomment-922893367) that we might be able to get rid of our weak linking of [`getauxval()`](https://man7.org/linux/man-pages/man3/getauxval.3.html) (`HAVE_WEAK_GETAUXVAL`) entirely, with only Android being a potential holdout:
> I wonder if it's time to get rid of HAVE_WEAK_GETAUXVAL. I think it's confusing. Either we build against a C library that has this functionality, or not. We don't do this weak linking thing for any other symbols and recently got rid of the other glibc backwards compatibility stuff.
> Unless there is still a current platform that really needs it (Android?), I'd prefer to remove it from the build system, it has caused enough issues.
After looking at Android further, it would seem that given we are moving to using `std::filesystem`, which [requires NDK version 22 and later](https://github.com/android/ndk/wiki/Changelog-r22), and `getauxval` has been available in the since [API version 18](https://developer.android.com/ndk/guides/cpu-features#features_using_libcs_getauxval3), that shouldn't really be an issue. Support for API levels < 19 will be dropped with the NDK 24 release, and according to [one website](https://apilevels.com/), supporting API level 18+ will cover ~99% of devices. Note that in the CI we currently build with NDK version 22 and API level 28.
The other change in this PR is removing the include of headers for ARM intrinsics, from the check for strong `getauxval()` support in configure, as they shouldn't be needed. Including these headers also meant that the check would basically only succeed when building for ARM. This would be an issue if we remove weak linking, as we wouldn't detect `getauxval()` as supported on other platforms. Note that we also use `getauxval()` in our RNG when it's available.
I've checked that with these changes we detect support for strong `getauxval()` on Alpine (muslibc). On Linux, previously we'd be detecting support for weak getauxval(), now we detect strong support. Note that we already require glibc 2.17, and `getauxval()` was introduced in `2.16`.
This is an alternative / supersedes #23030.

90be29c5b5 wallet: enable SQLite extended result codes (Sebastian Falbesoner)
Pull request description:
With this change, we get more fine-grained error messages if something goes wrong in the course of communicating with the SQLite database. To pick some random examples, the error codes SQLITE_IOERR_NOMEM, SQLITE_IOERR_CORRUPTFS or SQLITE_IOERR_FSYNC are way more specific than just a plain SQLITE_IOERR, and the corresponding error messages generated by sqlite3_errstr() will hence give a better hint to the user (or also to the developers, if an error report is sent) what the cause for a failure is.
See the SQLite documentation
https://www.sqlite.org/c3ref/extended_result_codes.htmlhttps://www.sqlite.org/c3ref/c_abort_rollback.html
> In its default configuration, SQLite API routines return one of 30 integer result codes. However, experience has shown that many of these result codes are too coarse-grained. They do not provide as much information about problems as programmers might like. In an effort to address this, newer versions of SQLite (version 3.3.8 2006-10-09 and later) include support for additional result codes that provide more detailed information about errors.

Pull request description:
On master (1ef34ee25e) during shutdown `QApplication` exits the main event loop, then re-enter again.
This PR streamlines shutdown process by removing the need to interrupt the main event loop, that is required for #59.
Also, blocking [`QDialog::exec()`](https://doc.qt.io/qt-5/qdialog.html#exec) calls are replaced with safer [`QDialog::show()`](https://doc.qt.io/qt-5/qwidget.html#show), except for `SendConfirmationDialog` as that change is not trivial (marked as TODO).
The [`QDialog::open()`](https://doc.qt.io/qt-5/qdialog.html#open) was not used because the actual modality mode (application modal or window modal) of a dialog depends on whether it has a parent.
This PR does not change behavior, and all touched dialogs are still application modal.
As a follow up, a design research could suggest to make some dialogs window modal.
NOTE for reviewers: quitting app while a dialog is open (e.g., via systray icon menu) must work fine.

We can avoid many unnecessary std::vector allocations by changing
CBloomFilter to take Spans instead of std::vector's for the `insert`
and `contains` operations.
CBloomFilter currently converts types such as CDataStream and uint256
to std::vector on `insert` and `contains`. This is unnecessary because
CDataStreams and uint256 are already std::vectors internally. We just
need a way to point to the right data within those types. Span gives
us this ability.

07b44f16e7 wallet: fix ComputeTimeSmart algorithm to use blocktime during old block rescanning (BitcoinTsunami)
Pull request description:
The function ComputeTimeSmart in wallet.cpp assume that transaction are discovered in the right order.
Moreover the 'smarttime' determination algorithm is coded with realtime scenario in mind and not rescanning of old block.
The functional test demonstrate that if the user import a wallet, then rescan only recent history, and then rescan the entire history, the older transaction discovered would have an incorrect time determination.
In the context of rescanning old block, the only time value that as a meaning is the blocktime.
That's why I've fixed the problem with a simple separation between rescanning of old block and realtime time determination. The fix is written to have no impact on every realtime scenario and only impact the behaviour during a rescanning process.
This PR Fixes#20181.
To be fair, I don't think that this bug could be triggered with the wallet GUI, because it always proceed with a proper rescan.
But RPC API provide the possibility to trigger it. I've discovered it, because Specter desktop v0.10.0 was impacted. (https://github.com/cryptoadvance/specter-desktop/issues/680).
