> I see unconditional log messages [net:warning] pcp: Could not receive response: Connection refused (111) every 5 minutes (in an environment where PCP is expected to not work), and it's a bit spammy. How about a exponential backoff, similar to how it's done in torcontrol.cpp?

Fair point, this suggestion was not correct.

The intent of the suggestion was more for the cosmetic angle so that the reader doesn't wonder why a standalone RPC is here without the presence of an assertion or usage of the returned value. Maybe there is an opportunity to introduce an `assert_no_rpc_error` helper here but need not be done now.

Add an optional matrix field allowing opt-out of configuring cirrus GHA cache when not using cirrus runners.

This is not needed for the cirruslabs/[save|restore]-cache actions, as they automatically fallback based on runner type.

const [Params = <char[15], int>]] [fromme] RescanFromTime: Rescanning last 7 blocks
```

Ah, I see now that last 7 blocks are rescanned and 10 blocks are generated previously - so the transaction is indeed not rescanned.

Maybe the following diff for clarity:
```diff
- # Mock time forward and generate blocks so that the import does not rescan the transaction
+ # Mock time forward and generate enough blocks so that the import does not rescan the transaction
```

Missing `return ` here.

This will lead to `ReadRawTransaction()` being called anyway and in my testing it returns an empty vector, which we then discover on line 533 and on the next line we try to use `req` again but internal pointers have been reset to null by the line of this comment, leading to a crash.

I am going to NACK every PR that adds even more `-Werror`. 30f642952cb5bf39479bdbe467b3950f0d09324a was a mistake and should be reverted. The correct approach to this is [`CMAKE_COMPILE_WARNING_AS_ERROR`](https://cmake.org/cmake/help/latest/variable/CMAKE_COMPILE_WARNING_AS_ERROR.html).

Yes, that requires CMake 3.24 and we allow 3.22 as the minimum. It does not matter. Just accept that the setting will have no effect on Ubuntu 22.04. :man_shrugging:

Currently, the `actions/checkout@v5` checks out pull requests merged against master, which is what we want.

However, sometimes, it checks out ancient/stale merge commits. For example:

* https://github.com/bitcoin/bitcoin/actions/runs/17458152407/job/49579638898?pr=29641#step:9:914 compiles with IPC=ON, even though latest master is at ed2ff3c63d83e275b0785a695fa4db38870abf1a
* https://github.com/bitcoin/bitcoin/pull/32989#issuecomment-3133536724 (example explained in comment)

`any || true`, will just be `true`, no?

Also, the error looks the same, so this has no effect?

`CLI_MAX_ARG_SIZE` has many edge case issues:

* It seems to be lower on some systems, but it is unknown how to reproduce locally: https://github.com/bitcoin/bitcoin/pull/33079#issuecomment-3139957274
* `MAX_ARG_STRLEN` is a limit per arg, but we probably want "The maximum length of [all of] the arguments": See https://www.man7.org/linux/man-pages/man3/sysconf.3.html, section `ARG_MAX - _SC_ARG_MAX`.
* It doesn't account for the additional args added by the `bitcoin` command later on: https:

> [30f6429](https://github.com/bitcoin/bitcoin/commit/30f642952cb5bf39479bdbe467b3950f0d09324a) was a mistake...

Here is some historical context.

When migrating the build system from Autotools to CMake, there was a unanimous expectation that, at least initially, we should aim for 100% build option compatibility. That commit introduced CMake’s counterpart to Autotools’ `--enable-werror`:https://github.com/bitcoin/bitcoin/blob/6e62b705328f4a52875a1dd3bfb63fbba8586a01/configure.ac#L284-L289

That seems acceptable to me, as none of the CI jobs use CMake older that 3.24. And when someone sets `CMAKE_COMPILE_WARNING_AS_ERROR` with an older CMake, it issues a warning:
```
CMake Warning:
Manually-specified variables were not used by the project:

CMAKE_COMPILE_WARNING_AS_ERROR

If I understand correctly - the expected behaviour for `actions/checkout@v5` for `pull_request` is to checkout a temporary merge commit onto the merge branch, which should be re-evaluated every time the workflow is reran (e.g. a manual trigger), which is what we want to avoid silent merge conflicts. But you've observed that in some cases, the merge branch (`GITHUB_REF`) is stale. Do you know why that is happening, and is this an upstream bug? I've browsed the documentation and https://github.com
