Huh false alarm I guess. I must not have done a clean rebuild.

Fixed the typo in the description.

I added "all calls to" to the first item.

Added a link to your comment for the list of exceptions.

We can change that later, but currently the (guix built) release binaries are shipped with `test_bitcoin` - for whatever reason.

💬 Sjors commented on pull request "multiprocess: Add bitcoin wrapper executable":
(https://github.com/bitcoin/bitcoin/pull/31375#discussion_r1894540173)
The goal of #31098 is to have `bitcoin-node` included in the release. For the time being only stratum v2 (or other IPC mining interface consumers) should use that binary. And they will get instructions for that. By default folks should run `bitcoind`.

Once the multiprocess bundled binaries are mature enough and there's a broader benefit to using them (e.g. the GUI can connect to the node), we could change the default.

Nice solution to use `127.0.0.1:1` as unreachable proxy for DNS requests too. I [ran](https://cirrus-ci.com/build/4807331864641536) this on my CI runners with a `8.8.8.8` and `1.1.1.1` as DNS servers as [before](https://github.com/bitcoin/bitcoin/pull/31349#issuecomment-2499335672) and the tests don't connect out now. I [ran](https://cirrus-ci.com/build/6328887816224768) with `test: avoid generating non-loopback traffic from feature_config_args.py`

Right, on an ephemeral runner, this won't persist across runs - it's gone when the host shuts down. I'll remove it and clarify in the docs that `DOCKER_BUILD_CACHE_HOST_DIR` is for ephemeral runners.

Using `mktemp --directory ci-docker-build-cache-XXXXXXXXXX` to allow a non-ephemeral host have a chance to identify them based on the prefix and clean them up.

i'll review/test your PR when ready.

i think 1 ,3 and 4 could/should be optional as it also can be handled by the process reading the pipe

See above note about `-signetchallenge`.

When used as an argument it is `-signetchallenge`, perhaps use that here as well.

> * Creating a new RPC call for undo data, say `getblockundo`. This would be perfect for my needs, but it would require making the undo data serialization format non-internal (not sure if this would be a problem, as IIRC it hasn't changed in many years).

By [adding a new REST endpoint for fetching block prevouts]((https://github.com/bitcoin/bitcoin/commit/dd76731db48ce85073d987f804936c0bab6a07a2)), it seems that we can get quite a good throughput rate when reading the data concurrently (teste

An alternative implementation of https://github.com/bitcoin/bitcoin/pull/31539, where the whole block is read into memory instead of doing it in chunks, as suggested by @theuni.

This is a follow-up to https://github.com/bitcoin/bitcoin/pull/31490 (first few commits duplicated here, hence a draft) and a precursor to https://github.com/bitcoin/bitcoin/pull/31144.

Renamed to `DANGER_DOCKER_BUILD_CACHE_HOST_DIR`, moved the docs to `ci/test/02_run_container.sh` and not touching `ci/test/00_setup_env.sh` anymore, dropped `rm -rf "${DOCKER_BUILD_CACHE_TEMPDIR}"` but documented that non-ephemeral hosts would need to take care of cleaning up the temp dirs, and gave the temp dirs a `ci-docker-build-cache-` prefix. Thanks @maflcko.
