71656bdfaa gui: crash fix, disconnect numBlocksChanged() signal during shutdown (furszy)
Pull request description:
Aiming to fixbitcoin-core/gui#862.
The crash stems from the order of the shutdown procedure:
We first unset the client model, then destroy the wallet controller—but we leave
the internal wallet models (`m_wallets`) untouched for a brief period. As a result,
there’s a point in time where views still have connected signals and access to
wallet models that are not connected to any wallet controller.
Now.. since the `clientModel` is only replaced with nullptr locally and not destroyed
yet, signals like `numBlocksChanged` can still emit. Thus, when wallet views receive
them, they see a non-null wallet model ptr, and proceed to call backend functions
from a model that is being torn down.
As the shutdown procedure begins by unsetting `clientModel` from all views. It’s safe
to ignore events when `clientModel` is nullptr.

PR #30356 incorrectly changed a constant of `4000` to `m_options.coinbase_max_additional_weight` in the check for when to give up finding another transaction to fill the block:
```diff
if (nConsecutiveFailed > MAX_CONSECUTIVE_FAILURES && nBlockWeight >
- m_options.nBlockMaxWeight - 4000) {
+ m_options.nBlockMaxWeight - m_options.block_reserved_weight) {
// Give up if we're close to full and haven't succeeded in a while
break;
}
```
But this constant did not deal with the reserved weight at all. It was in fact simply checking if the block was close to full, and if so, giving up finding another transaction to pad it with after `MAX_CONSECUTIVE_FAILURES` failed attempts.
It doesn't seem very logical to reuse the reserve weight for this purpose, and it would be overcomplicated to add yet another setting, so this PR changes it to a new constexpr.
Homebrew’s `qt@6` package places the `translations` and `plugins`
directories in the `share/qt` subdirectory.
This change updates the `macdeployqtplus` script accordingly.

The Consensus Cleanup soft fork proposal includes enforcing that coinbase transactions set their
locktime field to the block height, minus 1 (as well as their nSequence such as to not disable the
timelock). If such a fork were to be activated by Bitcoin users, miners need to be ready to produce
compliant blocks at the risk of losing substantial amounts mining would-be invalid blocks. As miners
are unfamously slow to upgrade, it's good to make this change as early as possible.
Although Bitcoin Core's GBT implementation does not provide the "coinbasetxn" field, and mining
pool software crafts the coinbase on its own, updating the Bitcoin Core mining code is a first step
toward convincing pools to update their (often closed source) code. A possible followup is also to
introduce new fields to GBT. In addition, this first step also makes it possible to test future
Consensus Cleanup changes.
The changes to the seemingly-unrelated RBF tests is because these tests assert an error message
which may vary depending on the txid of the transactions used in the test. This commit changes the
coinbase transaction structure and therefore impact the txid of transactions in all tests.
The change to the "Bad snapshot" error message in the assumeutxo functional test is because this
specific test case reads into the txid of the next transaction in the snapshot and asserts the error
message based it gets on deserializing this txid as a coin for the previous transaction. As this
commit changes this txid it impacts the deserialization error raised.
This commit fixes the path listed in the documentation for the fuzz
testing test_runner.py. Previously the --help option worked but running
fuzz tests from the documented path did not.
A bug in 0.21.x and 22.x resulted in some wallets having invalid
derivation paths that are the concatenation of two derivation paths.
These appear only when inactive hd chains are topped up.
Since key metadata is a legacy wallet only record, migrating legacy
wallets to descriptor wallets will fix this issue as all key metadata
records are deleted. The derivation path information is derived
on-the-fly from the descriptor that is produced for the inactive hd
chain.
Thus we only need a test to verify that the derivation paths are good,
and that all key metadata records are deleted from the migrated wallet.
`CConnman::AlreadyConnectedToAddress()` searches the existent nodes by
address or by address-and-port:
```cpp
FindNode(static_cast<CNetAddr>(addr)) || FindNode(addr.ToStringAddrPort())
```
but:
* if there is a match by just the address, then the address-and-port
search will not be evaluated and the whole condition will be `true`
* if the there is no node with the same address, then the second search
by address-and-port will not find a match either.
The search by address-and-port is comparing against `CNode::m_addr_name`
which could be a hostname, e.g. `"node.foobar.com:8333"`, but
`addr.ToStringAddrPort()` is always going to be numeric.
Non-range desc are always added to the wallet with the range [0,0]. After the descriptor is added, the wallet will TopUp the keypool. For non-range descriptors, this process updates the desc range to [0,1].
Any attempts to update this non-range descriptor with a [0,0] range will result in an error because the range checks rejects new ranges not included in the old range.
Since this is a non-range desc, the range information should be disregarded and AddWalletDescriptor should always succeed regardless of provided range information
3dbd50a576 Fix failing util_time_GetTime test on Windows (VolodymyrBg)
Pull request description:
Remove unreliable steady clock time checking from the test that was causing CI failures primarily on Windows. The test previously tried to verify that steady_clock time increases after a 1ms sleep, but this approach is not reliable on all platforms where such a short sleep interval may not consistently result in observable clock changes.
This addresses issue #32197 where the test was reporting failures in the cross-built Windows CI environment. As noted in the discussion, the test is not critical to the functionality of Bitcoin Core, and removing the unreliable part is the most straightforward solution.

c99667583d validation: fix traversal condition to mark BLOCK_FAILED_CHILD (stratospher)
Pull request description:
This PR addresses 3 issues related to how `BLOCK_FAILED_CHILD` is set:
1. In `InvalidateBlock()`
- Previously, `BLOCK_FAILED_CHILD` was not being set when it should have been.
- This was due to an incorrect traversal condition, which is fixed in this PR.
2. In `SetBlockFailure()`
- `BLOCK_FAILED_VALID` is now cleared before setting `BLOCK_FAILED_CHILD`.
3. In `InvalidateBlock()`
- if block is already marked as `BLOCK_FAILED_CHILD`, don't mark it as `BLOCK_FAILED_VALID` again.
Also adds a unit test to check `BLOCK_FAILED_VALID` and `BLOCK_FAILED_CHILD` status in `InvalidateBlock()`.
<details>
<summary><h3>looking for feedback on an alternate approach</h3></summary>
<br>
An alternate approach could be removing `BLOCK_FAILED_CHILD` since even though we have a distinction between
`BLOCK_FAILED_VALID` and `BLOCK_FAILED_CHILD` in the codebase, we don't use it for anything. Whenever we check for BlockStatus, we use `BLOCK_FAILED_MASK` which encompasses both of them. See similar discussion in https://github.com/bitcoin/bitcoin/pull/16856.
I have a branch with this approach in https://github.com/stratospher/bitcoin/commits/2025_02_remove_block_failed_child/.
Compared to the version in #16856, it also resets `BLOCK_FAILED_CHILD` already on disk to `BLOCK_FAILED_VALID` when loading from disk so that we won't be in a dirty state in a no-`BLOCK_FAILED_CHILD`-world.
I'm not sure if it's a good idea to remove `BLOCK_FAILED_CHILD` though. would be curious to hear what others think of this approach.
thanks @ mzumsande for helpful discussion regarding this PR!

Pull request description:
Removed duplicate call to GetDescriptorScriptPubKeyMan and
Instead of checking linearly I have used find method so time complexity reduced significantly for GetDescriptorScriptPubKeyMan
after this fix improved performance of importdescriptor part refs https://github.com/bitcoin/bitcoin/issues/32013.
**Steps to reproduce in testnet environment**
**Input size:** 2 million address in the wallet
**Step1:** call importaddresdescriptor rpc method
observe the time it has taken.
**With the provided fix:**
Do the same steps again
observe the time it has taken.
There is a huge improvement in the performance. (previously it may take 5 to 6 seconds now it will take 1 seconds or less)
main changes i've made during this pr:
1. remove duplicate call to GetDescriptorScriptPubKeyMan method
2. And inside GetDescriptorScriptPubKeyMan method previously we checking **each address linearly** so each time it is calling HasWallet method which has aquired lock.
3. Now i've modified this logic call **find method on the map (O(logn)**) time it is taking, so only once we calling HasWallet method.
**Note:** Smaller inputs in the wallet you may not see the issue but huge wallet size it will definitely impact the performance.

Legacy wallets do not have the descriptors flag set. Don't load wallets
without the descriptors flag.
At the same time, we will no longer load BDB databases since they are
only used for legacy wallets.
Removes all legacy wallet specific functional tests.
Also removes the --descriptor and --legacy-wallet options as these are
no longer necessary with the legacy wallet removed.

1da11dbc44 bench: clean up migrated descriptor wallets via loader teardown (Lőrinc)
Pull request description:
The low-priority `WalletMigration` benchmark existed for some time but was never run automatically in our CI.
Although the failure first surfaced on Windows as a hang during temporary directory cleanup, it could also be reproduced on Linux and macOS when forcing multiple iterations (e.g. via a long `--min-time`).
### Root causes
1. **Leaked open wallets on Windows**
`MigrateLegacyToDescriptor` produces two new descriptor wallets (the primary spendable wallet and a companion watch‑only wallet). Without unloading them, their database files remained open in the `WalletContext`, blocking directory removal and hanging the test harness.
<details><summary>Details</summary>
```bash
what(): filesystem error: cannot remove all: The process cannot access the file because it is being used by another process [C:\Users\RUNNER\~1\AppData\Local\Temp\test_common bitcoin\WalletMigration\d8ffd89a7700ce01c31f] [C:\Users\RUNNER~1\AppData\Local\Temp\test_common bitcoin\WalletMigration\d8ffd89a7700ce01c31f\regtest\wallet.dat]
```
</details>
2. **Undefined behavior on repeated runs**
The benchmark body calls `std::move(wallet)`, invalidating the local `wallet` pointer. Running more than one iteration causes a use-after-move by the sanitizers.
<details><summary>Details</summary>
```bash
error: bench_bitcoin 0x00067927: DW_TAG_member '_M_local_buf' refers to type 0x00000000000b3ba7 which extends beyond the bounds of 0x0006791d

```
</details>
### Fixes
- **Automatic wallet teardown**
Wrap the benchmark in a `MakeWalletLoader` (owning a `WalletContext`), so that both migrated wallets are unloaded when the loader goes out of scope, eliminating any lingering open files.
- **Re-enable benchmarks in CI**
Drop the temporary filter in GitHub Actions. The `-sanity-check` run already executes each benchmark once, so `WalletMigration` now runs automatically without hangs or crashes.
- **Single iteration**
Configure the microbenchmark with `.epochs(1).epochIterations(1)`, ensuring the migration code runs exactly once and avoiding use-after-move.
No measurable change in benchmark performance.
