35e57fbe336cdcb348ff088fc04216f1f5cf2742 depends: Fix cross-compiling `qt` package from macOS to Windows (Hennadii Stepanov)
Pull request description:
Native packages cannot be used during cross-compiling. However, Qt still unconditionally tries to find them, which causes issues in some cases, such as when [cross-compiling from macOS to Windows](https://github.com/bitcoin/bitcoin/issues/32346).
This PR explicitly disables this unnecessary Qt behaviour.
Fixes https://github.com/bitcoin/bitcoin/issues/32346.
Here is a full workflow on my macOS Sequoia 15.4.1 (Intel):
```
% brew install make cmake ninja mingw-w64 nsis
% gmake -C depends -j 10 HOST=x86_64-w64-mingw32
% cmake -B build --toolchain depends/x86_64-w64-mingw32/toolchain.cmake
% cmake --build build -j 10 -t deploy
```

The original recursive `FindChallenges` explores the Miniscript node tree using depth-first search. Specifically, it performs a pre-order traversal (processing the node's data, then recursively visiting children from left-to-right). This recursion uses the call stack, which can lead to stack overflows on platforms with limited stack space, particularly noticeable in Windows debug builds.
This change replaces the recursive implementation with an iterative version using an explicit stack. The iterative version also performs a depth-first search and processes the node's data before exploring children (preserving pre-order characteristics), although the children are explored in right-to-left order due to the LIFO nature of the explicit stack.
Critically, both versions collect challenges into a `std::set`, which automatically deduplicates and sorts elements. This ensures that not only the final result, but the actual state of the set at any equivalent point in traversal remains identical, despite the difference in insertion order.
This iterative approach is an alternative to increasing the default stack size (as proposed in #32349) and directly addresses the stack overflow issue reported in #32341 by avoiding deep recursion.
The change is done in two commits:
* add a new iterative `FindChallenges` method and rename the old method to `*_recursive` (to simplify removal in the next commit), asserting that its result matches the original;
* Remove the original recursive implementation.
This approach avoids needing to suppress `misc-no-recursion` warnings and provides a portable, low-risk fix.
Using a `std::set` is necessary for deduplication, matching the original function's behavior. An experiment using an `std::vector` showed duplicate challenges being added, confirming the need for the set:

f57db75e91dec7e57a7eecfd5f6c914f278bc543 build: Use `-z noseparate-code` on NetBSD < 11.0 (David Gumberg)
Pull request description:
Follow up to #32038 which dropped `NO_HARDEN` from depends builds, this PR drops the `ENABLE_HARDENING` build option since disabling hardening of binaries should not be a supported or maintained use case. With this change, hardening flags are always enabled.
Individual hardening flags and options can still be disabled by appending flags, e.g.:
```bash
cmake -B build \
-DAPPEND_CPPFLAGS='-U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0 -fno-stack-protector -fcf-protection=none -fno-stack-clash-protection' \
-DAPPEND_LDFLAGS='-Wl,-z,lazy -Wl,-z,norelro -Wl,-z,noseparate-code'
```
There is an issue with NetBSD 10.0's dynamic linker that makes one of the hardening linker flags, `-z separate-code`, [problematic](https://github.com/bitcoin/bitcoin/pull/28724#issuecomment-2589347934), so this PR also introduces a check to prevent the use of this flag in NetBSD versions < 11.0, (where this issue is [fixed](acf7fb3abf)). The fix for this [might be backported](https://mail-index.netbsd.org/tech-userlevel/2023/01/05/msg013670.html) to NetBSD 10.0.
I suggest reviewing the diff with whitespace changes hidden (`git diff -w` or using github's hide whitespace option)

71656bdfaa6bfe08ce9651246a3ef606f923351b 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.

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.
3dbd50a576be55941cb4b5034dc2171c03afb07c 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.

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!

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.

Also removes the --descriptor and --legacy-wallet options as these are
