706c8e096978b694fb56dee9e8ed8f55373ad5a0 refactor: use `strprintf` for creating unknown-service-flag string (Sebastian Falbesoner)
Pull request description:
No need to use a stringstream here. The trivial change can be verified by running the functional test `rpc_net.py`:
c73c8d53fe/test/functional/rpc_net.py (L181-L184)
As far as I could tell, this is the only instace left where we used `std::ostringstream` for the creation of simple strings (in `FormatSubVersion` using a stream makes sense since the number of placeholders is not constant).

4edc6893825fd8c45c53c81c73a6a7801e1b458c doc: test: suggest multi-line imports in functional test style guide (Sebastian Falbesoner)
Pull request description:
As long as I remember contributing to functional tests (~2-3 years), it was always kind of an unwritten rule that multi-line imports are preferred over single-line imports in order to reduce the possibility of potential merge conflicts -- at least if more than one symbol from a module is imported. This PR adds this rule to the style guide and adapts the example test accordingly. (Inspired by https://github.com/bitcoin/bitcoin/pull/25792#discussion_r941180819).

7a0b129c41d9fefdbc20d6d04983dd87bb8379e7 guix: patch NSIS to remove .reloc sections from install stubs (fanquake)
Pull request description:
With the release of binutils/ld 2.36, ld swapped to much improved
default settings when producing windows binaries with mingw-w64. One of
these changes was to stop stripping the .reloc section from binaries,
which is required for working ASLR.
When we switched to using a newer Guix time-machine in #23778, we begun
using binutils 2.37 to produce releases. Since then, our windows
installer (produced with makensis) has not functioned correctly when run on
a Windows system with the "Force randomization for images (Mandatory ASLR)"
option enabled. Note that all of our other release binaries, which all
contain .reloc sections, function fine under the same option, so it
cannot be just the presence of a .reloc section that is the issue.
The root cause of the problem is that when we compile NSIS (makensis), a number
of exe installer stubs are produced at the same time, for use later when makensis
is actually run. Given the new linker defaults, the stubs will contain .reloc sections,
when previously they would not. It seems that, in combination with how makensis
mutates the stub when it actually builds the installer, causes the problem.
According to upstream, https://sourceforge.net/p/nsis/bugs/1131/#abb6:
> Looks like the problem is the very existance of the .reloc section.
> It's not supposed to be there, and makensis doesn't handle it.
The most recent .reloc related upstream activity is in
https://sourceforge.net/p/nsis/bugs/1283/, where the conclusion again seemed to
be that .relo sections are not wanted, but there hasn't been any further follow up.
For now, restore pre-binutils-2.36 behaviour, by passing `-Wl,--disable-reloc-section`
to the linker when building the installer stubs, which fixes the produced installer.
The underlying issue can be further investigated in future.
.reloc section stripping is something we've accounted for previously,
see #18702, and related upstream discussion is in this thread:
https://sourceware.org/bugzilla/show_bug.cgi?id=19011.
Fixes#25726.

* No such error was present on Bitcoin.
It is true, that no `std::ostream& operator<<(std::ostream& a, const std::byte& b)` is present by default but attempting to `grep` for any specializations didn't show anything _relevant_ that Dash didn't have. Searching on GitHub didn't help either.
* Then, assuming that perhaps Boost's assertion logic may have changed, upgraded the version of Boost to match the pull request at the time, Boost 1.81. That also did not do anything (and actually, caused a trailing slashes unit test to fail but doesn't cause any problem in Bitcoin because they got rid of their `boost::filesystem` usage by then).
* If that isn't it, then let's try building Bitcoin with Dash's depends. It built successfully, ran successfully. The problem isn't in the dependency, it's in the codebase.
* Since it seemed to be `std::byte` related, pull requests that are related to `std::byte` serialization were backported and `std::byte` serialization related changes needed for [dash#5902](https://github.com/dashpay/dash/pull/5902) were cherry-picked. That's why this pull request came to be. But it didn't help this particular issue (though it did smooth out the cherry-picks).
* Running out of ideas, `gdb` is used to step through `serialize_tests`'s `class_methods` and understand why `BOOST_CHECK_EQUAL(out.at(0), std::byte{'a'});` is valid in Bitcoin but not Dash by finding the elusive `operator<<`. This is where things go from bad to worse.
Turns out, when you build with `clang`, `gdb` loses the ability to do breakpoints by file. So, an attempt is made to use `lldb` (which btw, is called `lldb-16`, running `lldb` with yield an error if you're using the develop container) and it refuses to work, erroring `personality set failed: Operation not permitted`.
Turns out, the [`docker-compose.yml`](37f43e4e56/contrib/containers/develop/docker-compose.yml) needs the following additions:
```
cap_add:
- SYS_PTRACE
security_opt:
- "seccomp:unconfined"
```
After making these changes, `lldb` works and then we resume trying to find `operator<<`. After too many hours and nimbly alternating between `next` and `step`, tried making a return to `gdb` (compiling with `gcc` this time with the appropriate `CXXFLAGS`) hoping for different results and a while later, realized that it cannot step through Boost's headers (it doesn't recognize the filenames) and then recompile it with `clang` and return to `lldb`.
This was a wild goose chase.
* After a lot of futile efforts to find the operator by stepping through `BOOST_CHECK_EQUAL`, a basic example addressing the static assertion (that a left shift operator must exist of `<type>` (here `std::byte`) for `std::ostream`) was added in
```c++
std::ostream& ostr = std::cout;
ostr << std::byte{'a'};
```
...and it compiled in both codebases.
So the left shift that Boost is asserting doesn't exist does exist but it isn't being detected for some reason. Upon hovering the `<<`, VSCode highlighted the source of the definition as [`setup_common.h`](96ac317c27/src/test/util/setup_common.h (L27-L32)) thanks to the comment above it.
Diffing between Bitcoin and Dash revealed the secret, the `operator<<` definition was placed under namespace `std` by [bitcoin#23497](https://github.com/bitcoin/bitcoin/pull/23497) in f7086fd8ff (see [change](f7086fd8ff/src/test/util/setup_common.h (L29-L35))).
That change has now been made in a separate commit.
## Breaking Changes
Changes in serialization APIs will make backports predating [bitcoin#23438](https://github.com/bitcoin/bitcoin/pull/23438) annoying but will _not_ change how data is stored on disk.

c09981d8ad fix: drop symlinks in immer subtree (pasta)
Pull request description:
## Issue being fixed or feature implemented
I've been playing around recently with the `github-merge.py` script recently; and while I've been able to create merges with it (see 73c90c8370 and 10ddf62dfb) it complains / refuses to trivially work with symlinks. I haven't been able to figure out exactly why it doesn't want symlinks, but I think it's related to the sha512sum hash that gets created.
I'm not sure if we'll start using `github-merge.py` more or not; but I guess we should "fix" this anyhow in order to learn more how these work. It may be useful to move to merging commits locally and not relying on github being a good actor? 🤷
## What was done?
## How Has This Been Tested?
Ran `github-merge.py` locally and it no longer complains about symlinks
## Breaking Changes
None

304452558c7f6f5e32ba13d8f05325790c8a4f5f depends: expat 2.4.8 (fanquake)
Pull request description:
Currently, when building the expat package in depends, using `-flto` (`LTO=1`), the configure check can fail, because it cannot determine the system endianess:
```bash
configure:18718: result: unknown
configure:18733: error: unknown endianness
presetting ac_cv_c_bigendian=no (or yes) will help
```
Fix that by defining `_DEFAULT_SOURCE`, which in turn defines `__USE_MISC` (`features.h`):
```c
#if defined _DEFAULT_SOURCE
# define __USE_MISC1
#endif
```
which exposes additional definitions in `endian.h`:
```c
#include <features.h>
/* Get the definitions of __*_ENDIAN, __BYTE_ORDER, and __FLOAT_WORD_ORDER. */
#include <bits/endian.h>
#ifdef __USE_MISC
# define LITTLE_ENDIAN__LITTLE_ENDIAN
# define BIG_ENDIAN__BIG_ENDIAN
# define PDP_ENDIAN__PDP_ENDIAN
# define BYTE_ORDER__BYTE_ORDER
#endif
```
and gives us a working configure.
You could test building this change with Guix + LTO with [this branch](https://github.com/fanquake/bitcoin/tree/lto_in_guix). Note that that build may fail for other reasons (on x86_64), unrelated to this change.

Pull request description:
Make a note about a potentially confusing behavior with `BaseIndex::m_synced`;
if the user starts bitcoind with an empty datadir and an index enabled,
BaseIndex will consider itself synced (as a degenerate case). This affects
how indices are built during IBD (relying solely on BlockConnected signals vs.
using ThreadSync()).

fa7238300c18938cdf627cacfc58d4b81602417f fuzz: Limit fuzzed time to years 2000-2100 (MarcoFalke)
Pull request description:
It doesn't make sense to fuzz times in the past, as Bitcoin Core will refuse to start in the past.
Fix that and also remove a sanitizer suppression, which would be hit in net_processing in `ProcessMessage`:
```cpp
if (addr.nTime <= 100000000 || addr.nTime > nNow + 10 * 60)
addr.nTime = nNow - 5 * 24 * 60 * 60; // <-- Here
```
This changes the format of fuzz inputs. Previously a time value was (de)serialized as 40 bytes, now it is 32 bytes.
