22cff32319 doc: recommend gmake for FreeBSD (Sjors Provoost)
b645c52071 doc: recommend modern make for macOS depends (Sjors Provoost)
99e6490dc5 doc: shuffle depends instructions (Sjors Provoost)
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.

GetAll() is non-const, preventing CheckBlockIndex() from being
const. Rather than add a const GetAll() method, just iterate over
the chainstates directly.
Slight behaviour change by also subjecting non-`IsUsable()`
chainstates to consistency checks.
Native compilation is explained before cross-compilation. Move
install and (g)make steps up.
In the Configuring section, use Linux native compilation as the
example instead of Windows cross-compile.
Closes: #11800
Note: In certain rare edge cases, monotonically increasing estimates may
not be guaranteed. Specifically, given two targets N and M, where M > N,
if a sub-estimate for target N fails to return a valid fee rate, while
target M has valid fee rate for that sub-estimate, target M may result
in a higher fee rate estimate than target N.

In order to remove potential confusion, this commit adapts all script
error constant names in the functional tests (currently only in
feature_taproot.py) to the ones used in our C++ codebase. This also
makes checking whether we have test coverage for a certain script error
easier.

Add missing error check for fcntl(fd, F_GETFD, 0) in set_clo_on_exec.
Raise OSError on failure to align with existing FD_SETFD behavior.
This improves robustness in subprocess setup and error visibility.

* 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
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:
```
==1578139== 472 bytes in 1 blocks are still reachable in loss record 1 of 1

```
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:
```

...
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.
