* refactor: Guard `util::quote_argument()` with `#ifdef __USING_WINDOWS__`
The `util::quote_argument()` function is specific to Windows and is used
in code already guarded by `#ifdef __USING_WINDOWS__`.
* Do not escape double quotes for command line arguments on Windows
This change fixes the handling of double quotes and aligns the behavior
with Python's `Popen` class. For example:
```
>py -3
>>> import subprocess
>>> p = subprocess.Popen("cmd.exe /c dir \"C:\\Program Files\"", stdout=subprocess.PIPE, text=True)
>>> print(f"Captured stdout:\n{stdout}")
```
Currently, the same command line processed by the `quote_argument()`
function looks like `cmd.exe /c dir "\"C:\Program" "Files\""`, which is
broken.
With this change, it looks correct: `cmd.exe /c dir "C:\Program Files"`.

This suppresses the following warning caused by clang-20.
```
error: definition of implicit copy constructor for 'Streams' is deprecated because it has a user-declared copy assignment operator [-Werror,-Wdeprecated-copy]
```
Copy constructor or move constructor is called when std::vector re-allocates
memory. In this case, move constructor should be called, because copying
Streams instances breaks file-descriptor management.
Communication class is modified as well, since it's instance is a member of
Streams class.

The commit a32c0f3df4b6bcd1d2e93f19e8f380bb890cd507 introduced code to
silence MSVC's "warning C4996: The POSIX name for this item is
deprecated."
However, it exhibits several issues:
1. The aliases may leak into code outside the `subprocess.hpp` header.
2. They are unnecessarily applied when using the MinGW-w64 toolchain.
3. The fix is incomplete: downstream projects still see C4996 warnings.
4. The implementation lacks documentation.
This change addresses all of the above shortcomings.

When passing in a rvalue reference, compiler
considers it ambiguous between std::string and
std::string&&. Making one of them take a lvalue
reference makes compilers correctly pick the right
one depending on whether the passed in value binds

I encountered this issue while running my code with Valgrind today.
Below is part of the Valgrind error message:

I noticed that a similar fix had been proposed by another contributor

it sooner so other people don't get confused by it just as I did today.

0ad7d7abdb test: chainstate write test for periodic chainstate flush (Andrew Toth)
Pull request description:
Since #28233, periodically writing the chainstate to disk every 24 hours does not clear the dbcache. Since #28280, periodically writing the chainstate to disk is proportional only to the amount of dirty entries in the cache. Due to these changes, it is no longer beneficial to only write the chainstate to disk every 24 hours. The periodic flush interval was necessary because every write of the chainstate would clear the dbcache. Now, we can get rid of the periodic flush interval and simply write the chainstate along with blocks and block index at least every hour.
Three benefits of doing this:
1. For IBD or reindex-chainstate with a combination of large dbcache setting, slow CPU, slow internet speed/unreliable peers, it could be up to 24 hours until the chainstate is persisted to disk. A power outage or crash could potentially lose up to 24 hours of progress. If there is a very large amount of dirty cache entries, writing to disk when a flush finally does occur will take a very long time. Crashing during this window of writing can cause https://github.com/bitcoin/bitcoin/issues/11600. By syncing every hour in unison with the block index we avoid this problem. Only a maximum of one hour of progress can be lost, and the window for crashing during writing is much smaller. For IBD with lower dbcache settings, faster CPU, or better internet speed/reliable peers, chainstate writes are already triggered more often than every hour so this change will have no effect on IBD.
2. Based on discussion in #28280, writing only once every 24 hours during long running operation of a node causes IO spikes. Writing smaller chainstate changes every hour like we do with blocks and block index will reduce IO spikes.
3. Faster shutdown speeds. All dirty chainstate entries must be persisted to disk on shutdown. If we have a lot of dirty entries, such as when close to 24 hours or if we sync with a large dbcache, it can take a long time to shutdown. By keeping the chainstate clean we avoid this problem.

97eaadc3bf util: Remove `fsbridge::get_filesystem_error_message()` (Hennadii Stepanov)
Pull request description:
The `fsbridge::get_filesystem_error_message()` function exhibits several drawbacks:
1. It was introduced in https://github.com/bitcoin/bitcoin/pull/14192 to account for platform-specific variations in
`boost::filesystem::filesystem_error::what()`. Since [migrating](https://github.com/bitcoin/bitcoin/pull/20744) to `std::filesystem`, those discrepancies no longer exist.
2. It fails to display UTF-8 paths correctly on Windows:
```

...
```
3. It relies on `std::wstring_convert`, which was deprecated in C++17 and removed in C++26 (also see https://github.com/bitcoin/bitcoin/issues/32361).
This PR removes the obsolete `fsbridge::get_filesystem_error_message()` function, thereby resolving all of the above issues.

The default/minimum key derivation rounds magic number of 25000 is hoisted into a constant (member of `CMasterKey`) and two new functions `EncryptMasterKey`/`DecryptMasterKey` are introduced in order to deduplicate code for the derivation round determination and master key en/decryption. Also, mentions of the never-implemented derivation method `scrypt` are removed from the wallet crypter header and both plain and encrypted master key instances are renamed to adapt to moderning coding style (hopefully improving readability).

524f981bb8 Bugfix: Miner: Don't reuse block_reserved_weight for "block is full enough to give up" weight delta (Luke Dashjr)
Pull request description:
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.

b80d0bdee4 test: avoid stack overflow in `FindChallenges` via manual iteration (Lőrinc)
Pull request description:
`FindChallenges` explores the `Miniscript` node tree by going deep into the first child's subtree, then the second, and so on - effectively performing a pre-order Traversal (Depth-First Search) recursively, using the call stack which can result in stack overflows on Windows debug builds.
This change replaces the recursive implementation with an iterative version using an explicit stack. The new implementation also performs a pre-order depth-first traversal, though it processes children in right-to-left order (rather than left-to-right) due to the LIFO nature of the stack. Since both versions store results in a `std::set`, which automatically sorts and deduplicates elements, the exact traversal order doesn't affect the final result.
It is an alternative to increasing the Windows stack size, as proposed in #32349, and addresses the issue raised in #32341 by avoiding deep recursion altogether.
The change is done in two commits:
* add a new iterative `FindChallenges` method and rename the old method to `*_recursive` (to simplify the next commit where we remove it), asserting that its result matches the original;
* remove the original recursive implementation.
This approach avoids ignoring the `misc-no-recursion` warning as well.
I tried modifying the new method to store results in a vector instead, but it demonstrated that the deduplication provided by `std::set` was necessary. One example showing the need for deduplication:
Recursive (using set):
```
(6, 9070746)
(6, 19532513)
(6, 3343376967)
```
Iterative (using vector attempt):
```
(6, 19532513)
(6, 9070746)
(6, 3343376967)
(6, 9070746) // Duplicate entry
```
The performance of the test is the same as before, with the recursive method.

Pull request description:
Fixes#27744
Since #27278 we log received headers. For compact blocks we also log which peer sent it (e5ce857634), but not for regular headers. That required an additional refactor, which this PR provides.
Move the logging from validation to net_processing.
This also reduces the number of log entries (under default configuration) per compact block header from 3 to 2: one for the header and one for the connected tip.
The PR introduces a new helper method `LogBlockHeader`.
When receiving a _compact block_ we call `LogBlockHeader` from the exact same place as where we previously logged. So that log message doesn't change. What does change is that we no longer _also_ log from `AcceptBlockHeader`.
When receiving a regular header(s) message, _we only log the last one_. This is a change in behaviour because it was simpler to implement, but it's probably better anyway. It does mean that if a peer sends of a bunch of headers of which _any_ is invalid, we won't log it (here).
Lastly I expanded the code comment explaining why we log this. It initially only covered selfish mining, but we also care about peers sending us headers but not following up (see e.g. #27626).

94e85a82a7 net: remove unnecessary check from AlreadyConnectedToAddress() (Vasil Dimov)
Pull request description:
`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.
---
In other words: let `A` be "CNetAddr equals" and `B` be "addr:port string matches", then:
* If `A` (is `true`), then `B` is irrelevant, so the condition `A || B` is equivalent to `A` is `true`.
* Observation in this PR: if `!A` (`A` is `false`), then `!B` for sure, thus the condition `A || B` is equivalent to `A` is `false`.
So, simplify `A || B` to `A`.
https://en.wikipedia.org/wiki/Modus_tollens `!A => !B` is equivalent to `B => A`. So the added fuzz test asserts that if `B` is `true`, then `A` is `true`.

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:
Example failure with vector:
Recursive (set):

Iterative (vector attempt):

(6, 9070746)
(6, 3343376967)
(6, 9070746) // Duplicate

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.

`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.
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.

9e29653b42 test: check BlockStatus when InvalidateBlock is used (stratospher)
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.
