Yes, I haven't looked at the code, but I presumed it was the same issue/fix.

No backport needed, the PR containing the code (#28155, commit 94e8882d820969ddc83f24f4cbe1515a886da4ea) was merged to master after 26.x branched off.

This:

* Removes dead code.
* Avoids unused copies in some places.
* Adds copies in other places for safety.

Thanks, I've taken the commit and put it in https://github.com/bitcoin/bitcoin/pull/29040, because it fits into the other fs::path changes

Asserting for the debug log message "Added connection peer=" is insufficient for ensuring that this new connection will show up in a following getpeerinfo() call, as the debug message is written in the CNode ctor, which means it hasn't necessarily been added to CConnman.m_nodes at this point.

Solve this by using the recently introduced `wait_for_new_peer` helper (see #29006, commit 00e0658e77f66103ebdeb29def99dc9f937c049d), which is more robust.

Fixes #29030.

It compiles OK.

What subset of benchmarks we might consider representative enough?

For now, I'm observing very tiny (a couple of %) improvements in some of them.

Also we should remember that MSVC build uses no optimisation (see e94ae810a55da16fce6040714677b9d50781bebd).

Thanks for taking the suggestions! Looks like the CI failure is a transient failure, I ran the same test locally and it passed. Probably just needs to be re-run.

Turns out "class template argument deduction for aggregates" is one of the few things implemented only in recent compilers, see https://en.cppreference.com/w/cpp/compiler_support/20

So clarify the comments.

There exist many usages of `fuzzed_data_provider` where it is evaluated directly in the function call.
Unfortunately, the order of evaluation of function arguments is unspecified, and a simple example shows that it can differ e.g. between clang++ and g++: https://godbolt.org/z/jooMezWWY

When the evaluation order is not consistent, the same fuzzing/random input will produce different output, which is bad for coverage/reproducibility. This PR fixes all these cases I have found where unspecifie

It is awkward not using optimization.
