fa4804009c fuzz: Remove unused TimeoutExpired catch in fuzz runner (MarcoFalke)
Pull request description:
Currently, the way to check for libFuzzer is to search the stderr of the fuzz executable when passed `-help=1` for the string `libFuzzer`. See also 14b8dfb2bd/contrib/devtools/deterministic-fuzz-coverage/src/main.rs (L90-L101)
The python test runner additionally includes a timeout catch, which was needed before the plain `read_file` fallback was implemented, see 14b8dfb2bd/src/test/fuzz/fuzz.cpp (L251).
However, it is no longer needed and the printed error message would be wrong, so remove it.
(side-note: On Windows the fuzz executable seems to time out when an assert is hit in a debug build, see https://github.com/bitcoin/bitcoin/issues/32341#issuecomment-2842716175. However, no one is running fuzz debug on Windows. Also, the newly added debug logging is a preferable replacement in this case anyway.)

b5f580c580 scripted-diff: adapt script error constant names in feature_taproot.py (Sebastian Falbesoner)
Pull request description:
While reviewing #31622 I noticed that the constant name `(SCRIPT_)ERR_SIG_HASHTYPE` is used for two different script verification error codes, namely one for legacy and one for Schnorr signatures:
eba5f9c4b6/src/script/script_error.cpp (L56-L57)eba5f9c4b6/test/functional/feature_taproot.py (L600)
In order to resolve this confusion, this PR adapts all script error constant names in the functional tests (currently only in feature_taproot.py) to the ones used in our C++ codebase (see [script_error.cpp](https://github.com/bitcoin/bitcoin/blob/master/src/script/script_error.cpp)) with a scripted diff. This also makes checking whether we have test coverage for a certain script error easier.

Pull request description:
This PR is splitting off some of the improvements made in #28985 and starts addressing the issues raised in #27754.
I aim to completely replace `coinselector_tests` with `coinselection_tests`. The goal is to generally use coins created per a nominal _effective value_ so we can get away from testing with `CoinSelectionParams` that are non-representative and effectuate counterintuitive behavior such as `feerate = 0` or `cost_of_change = 0`

Pull request description:
macOS ships with GNU Make 3.81 from 2006. This has caused
difficult to debug issues, e.g. #32070 and #30978.
Tell users / developers who use the depends system to install a modern version of `make`.
This PR does not change the non-depends build.
Although Homebrew allows overriding the system `make`, we instead just instruct users to build with `gmake`. This way there should be no impact on other projects they wish to compile.
To increase the likeliness of anyone actually seeing and following this instruction, the first commit moves things around in `depends/README.md`. It now starts with instructions for a local build and moves cross-compilation to the end. For each platform it shows what to install (`apt install`, `brew install`, etc) and what command to run (`make` or `gmake`).
There previously was no macOS specific section, so this is added. It points to the general `build-osx.md` for how to install the Xcode Command Line Tools and Homebrew Package Manager.
I didn't test on an empty system.

* 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"`.

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
to a rvalue or lvalue reference.

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
previously. I did not mean to scoop their work, but merely hoping to fix
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.

We do not need to repeat the same test multiple times because BnB is
deterministic and will therefore always have the same outcome.
Additionally, this test was redundant because it repeats the "Smallest
combination too big" test.
Originally these tests verified that at a SelectCoins level that a
solution with fewer inputs gets preferred at high feerates, and a
solution with more inputs gets preferred at low feerates. This outcome
relies on the behavior of BnB, so we move these tests under the umbrella
of BnB tests.
Originally these tests relied on SFFO to work.
Recreates the tests in a new test suite coinselection_tests.cpp that is
based on UTXOs being created per their effective values rather than
nominal values and uses transactions with non-zero feerates.
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:
```
> build\bin\Release\bitcoind.exe -datadir="C:\Users\hebasto\dd_₿_🏃" -regtest
...
2025-04-30T00:17:48Z DeleteAuthCookie: Unable to remove random auth cookie file: remove: Access is denied.: "C:\Users\hebasto\dd_?_??\regtest\.cookie"
...
```
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.

Pull request description:
This PR contains various cleanups around the wallet's master key encryption logic. 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.

b9d4d5f66a net: Use GetAdaptersAddresses to get local addresses on Windows (laanwj)
Pull request description:
Instead of a `gethostname` hack, which is not guaranteed to return all addresses, use the official way of calling `GetAdaptersAddresses` to get local network addresses on Windows.
Do the same checks as the UNIX path: interface is up, interface is not loopback.
Suggested by Ava Chow.
Addiional changes:
- Cleanup: move out `FromSockAddr` in `netif.cpp` from MacOS and use it everywhere appropriate. This avoids code duplication.

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).

f1b142856a test: Same addr, diff port is already connected (David Gumberg)
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`.
