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.

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!

55b931934a removed duplicate calling of GetDescriptorScriptPubKeyMan (Saikiran)
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.

The migration benchmark crashes if run more than once, because of `std::move(wallet)` and leaves subsequent iterations in an undefined state - avoiding `UndefinedBehaviorSanitizer` null‑dereference error.
`MigrateLegacyToDescriptor` returns both a spendable descriptor wallet and a watch‑only wallet.
If these remain attached, their files stay open and on Windows this can hang CI when removing the test directory.
By constructing them via `MakeWalletLoader` (which owns the `WalletContext`), both wallets are automatically unloaded when the loader is destroyed at the end.
This ensures no lingering handles or resource leaks when running the benchmark on CI with `-sanity-check`.

Instead of having `MakeScripts` infer what pubkeys need to go into the output `FlatSigningProvider`, have each of the `PubkeyProviders` that have `GetPubKey` and `GetPrivKey` called fill it directly with relevant keys and origins.
This allows for keys and origins to be added that won't directly appear in the output, which is necessary for `musig()` descriptors.

e3d7533ac9 test: improves tapscript unit tests (Ethan Heilman)
3e167085ba test: Ensures test fails if witness is not hex (Ethan Heilman)
Pull request description:
This commit creates new test utilities for future Taproot script tests within script_tests.json. The key features of this commit are the addition of three new tags: `#SCRIPT#`, `#CONTROLBLOCK#`, and `#TAPROOTOUTPUT#`. These tags streamline the test creation process by eliminating the need to manually generate these components outside the test suite.
* `#SCRIPT#`: Parses Tapscript and outputs a byte string of opcodes.
* `#CONTROLBLOCK#`: Automatically generates the control block for a given Taproot output.
* `#TAPROOTOUTPUT#`: Generates the final Taproot scriptPubKey.
This code was originally part of the OP_CAT PR https://github.com/bitcoin/bitcoin/pull/29247 but was pulled out into a separate PR to reduce the rebase treadmill for the OP_CAT PR.
Additionally this PR adds a check to ensure that if the witness data can not be parsed as hex the test fails. Prior to this PR, the test code would fail silently and set the values it couldn't parse as empty stack elements. This fix was suggested by @instagibbs.
## Rationale
While writing JSON script tests (script_tests.json) for https://github.com/bitcoin/bitcoin/pull/29247 we ran into the following problem. The JSON script tests are simple and easy to write for pre-Tapscript scripts, but adding or changing a Tapscript test requires substantial work per test. Consider the following pre-tapscript test:
```
["'aa' 'bb'", "CAT 0x4c 0x02 0xaabb EQUAL", "P2SH,STRICTENC", "DISABLED_OPCODE", "CAT disabled"]
````
whereas a Tapscript test for the same script (annotated with comments for better readability) would look like:
```
[
[
"aa",
"bb",
"7e4c02aabb87", // output script
"c0d6889cb081036e0faefa3a35157ad71086b123b2b144b649798b494c300a961d", // control block
0.00000001
],
"",
"0x51 0x20 0x15048ed3a65748549c27b671936987093cf73a4c9cb18522a74fb9553060ca99", // Tapscript output
"P2SH,WITNESS,TAPROOT",
"OK",
"TAPSCRIPT CATs aa and bb together and checks if EQUAL to aabb"
]
```
Computing the Tapscript output, such as `0x51 0x20 0x15048ed3a65748549c27b671936987093cf73a4c9cb18522a74fb9553060ca99`, requires writing custom code and running it for each test. The same is true for the Tapscript control block, such as `c0d6889cb081036e0faefa3a35157ad71086b123b2b144b649798b494c300a961d`. If a test is changed or updated new outputs and control blocks must be computed. The complexity of doing this is likely the reason that no one has added any Tapscript tests to JSON script tests until this PR.
In this PR we address this issue by adding the following improvements to JSON script tests:
Adding simple macros ("#SCRIPT# and #CONTROLBLOCK#) that allow the script test parser to automatically generate and inject a valid Tapscript output and control block to be computed automatically from the JSON script.
Allowing Tapscript scripts to use the human readable strings like pre-script scripts by marking the location of the script in the witness stack using #SCRIPT#. This transforms the unreadable script 7e4c02aabb87 into #SCRIPT# CAT 0x4c 0x02 0xaabb EQUAL.
This results in the following JSON script test which is far easier to write and easier to read.
```
[
[
"aa",
"bb",
"#SCRIPT# CAT",
"#CONTROLBLOCK#",
0.00000001
],
"",
"0x51 0x20 #TAPROOTOUTPUT#",
"P2SH,WITNESS,TAPROOT,OP_CAT",
"OK",
"TAPSCRIPT Test of OP_CAT flag by calling CAT on two elements. TAPSCRIPT_OP_CAT flag is set so CAT is executed."
],
```

5cb1241814 feefrac: avoid integer overflow in temporary (Pieter Wuille)
Pull request description:
In `FeeFrac::Div(__int128 n, int32_t d, bool round_down)` in src/util/feefrac.h, the following line computes the result:
```c++
return quot + (mod > 0) - (mod && round_down);
```
The function can only be called under conditions where the result is in range, and thus doesn't involve any integer overflow. However, the intermediary result computed by just `quot + (mod > 0)` may still overflow if it's going to be corrected by the `- (mod && round_down)` that follows.
Fix this by balancing the two correction steps with each other first:
```c++
return quot + ((mod > 0) - (mod && round_down));
```

2835216ec0 txgraph: make GroupClusters use partition numbers directly (optimization) (Pieter Wuille)
c72c8d5d45 txgraph: compare sequence numbers instead of Cluster* (bugfix) (Pieter Wuille)
Pull request description:
Part of cluster mempool: #30289
The implicit transaction ordering for transactions in a TxGraphImpl is defined by:
1. higher chunk feerate first
2. lower Cluster* object pointer first
3. lower position within cluster linearization first.
Number (2) is not deterministic, as it intricately depends on the heap allocation algorithm. Fix this by giving each Cluster a unique `uint64_t m_sequence` value, and sorting by those instead.
The second commit then uses this new approach to optimize GroupClusters a bit more, avoiding some repeated checks and dereferences, by making a local copy of the involved sequence numbers.
Thanks to @dergoegge for pointing this out.

fa6a007b8e fuzz: Avoid integer sanitizer warnings in policy_estimator target (MarcoFalke)
Pull request description:
It seems odd to write a fuzz target to trigger integer sanitizer warnings in `CBlockPolicyEstimator::processBlockTx` and then suppress them. If the scenario can happen in reality, the code should be properly fixed to handle the cases. If not, it seems better to fix the fuzz target to not trigger meaningless traces.
Do that here by keeping track of the current height and limiting mempool entries to at most this entry height.

I read the code and tried it out. Thus, making the doc explicitly mention it.

7749d929a0 Remove support for RNDR/RNDRRS for aarch64 on Linux (laanwj)
Pull request description:
This hardware feature is
- Rarely supported on SoCs (and broken on like half of the chips that support it in the first place) (#31817). It is not clear if, or how, the brokenness will be worked around in the kernel, but working around it in user space seems the wrong thing to do, this is not the place to maintain special workarounds for specific hardware (which despite that, was attempted in #31826, but had to be reverted in #31908 due to other problems).
- Apparently not compiled into the release binary anymore (https://github.com/bitcoin/bitcoin/issues/31817#issuecomment-2795885962). Did check this at the time, but a build system change must have caused this, and went undetected.
- Hard to test in CI (as well as manually), due to unavailability of hardware.
Better to remove it.
This reverts commit aee5404e02 from #26839.
Closes#31817.

Instead of GetPrivKey returning a key and having the caller fill the
FlatSigningProvider, have GetPrivKey take the FlatSigningProvider and
fill it by itself. This will be necessary for descriptors such as
musig() where there are private keys that need to be added to the
FlatSigningProvider but do not directly appear in any resulting scripts.
GetPrivKey is now changed to void as the caller no longer cares whether
it succeeds or fails.
Instead of having ExpandHelper fill in the origins in the
FlatSigningProvider output, have GetPubKey do it by itself. This reduces
the extra variables needed in order to track and set origins in
ExpandHelper.
Also changes GetPubKey to return a std::optional<CPubKey> rather than
using a bool and output parameters.
Legacy wallets should only import keys to the keypool if they came in a
single key descriptor. Instead of relying on assumptions about the
descriptor based on how many pubkeys show up after expanding the
descriptor, explicitly mark descriptors as being single key type and use
that for the check.

Pull request description:
This PR prevents Mining interface methods from sometimes crashing when called during startup before a tip is connected. It also makes other improvements like making more RPC methods usable from the GUI. Specifically this PR:
- Adds an `Assume` check to disallow passing negative timeout values to `Mining::waitTipChanged`
- Makes `waitfornewblock`, `waitforblock` and `waitforblockheight` RPC methods usable from the GUI when `-server=1` is not set.
- Changes `Mining::waitTipChanged` to return `optional<BlockRef>` instead of `BlockRef` and return `nullopt` instead of crashing if there is a timeout or if the node is shut down before a tip is connected.
- Changes `Mining::waitTipChanged` to not time out before a tip is connected, so it is convenient and safe to call during startup, and only returns `nullopt` on early shutdowns.
- Changes `Mining::createNewBlock` to block and wait for a tip to be connected if it is called on startup instead of crashing. Also documents that it will return null on early shutdowns.
This allows `waitNext()` (added in https://github.com/bitcoin/bitcoin/pull/31283) to safely assume `TipBlock()` isn't `null`, not even during a scenario of early shutdown.
Finally this PR clarifies long poll behaviour, mostly by adding code comments, but also through an early `break`.
