Merge bitcoin/bitcoin#28287: rpc, test: add sendmsgtopeer rpc and a test for net-level deadlock situation 
b3a93b409e test: add functional test for deadlock situation (Martin Zumsande)
3557aa4d0a test: add basic tests for sendmsgtopeer to rpc_net.py (Martin Zumsande)
a9a1d69391 rpc: add test-only sendmsgtopeer rpc (Martin Zumsande)

Pull request description:

  This adds a `sendmsgtopeer` rpc (for testing only) that allows a node to send a message (provided in hex) to a peer.
  While we would usually use a `p2p` object instead of a node for this in the test framework, that isn't possible in situations where this message needs to trigger an actual interaction of multiple nodes.

  Use this rpc to add test coverage for the bug fixed in #27981 (that just got merged):
  The test lets two nodes (almost) simultaneously send a single large (4MB) p2p message to each other, which would have caused a deadlock previously (making this test fail), but succeeds now.

  As can be seen from the discussion in #27981, it was not easy to reproduce this bug without `sendmsgtopeer`. I would imagine that `sendmsgtopeer` could also be helpful in various other test constellations.

README.md

Bitcoin Core integration/staging tree

https://bitcoincore.org

For an immediately usable, binary version of the Bitcoin Core software, see https://bitcoincore.org/en/download/.

What is Bitcoin Core?

Bitcoin Core connects to the Bitcoin peer-to-peer network to download and fully validate blocks and transactions. It also includes a wallet and graphical user interface, which can be optionally built.

Further information about Bitcoin Core is available in the doc folder.

License

Bitcoin Core is released under the terms of the MIT license. See COPYING for more information or see https://opensource.org/licenses/MIT.

Development Process

The master branch is regularly built (see doc/build-*.md for instructions) and tested, but it is not guaranteed to be completely stable. Tags are created regularly from release branches to indicate new official, stable release versions of Bitcoin Core.

The https://github.com/bitcoin-core/gui repository is used exclusively for the development of the GUI. Its master branch is identical in all monotree repositories. Release branches and tags do not exist, so please do not fork that repository unless it is for development reasons.

The contribution workflow is described in CONTRIBUTING.md and useful hints for developers can be found in doc/developer-notes.md.

Testing

Testing and code review is the bottleneck for development; we get more pull requests than we can review and test on short notice. Please be patient and help out by testing other people's pull requests, and remember this is a security-critical project where any mistake might cost people lots of money.

Automated Testing

Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code. Unit tests can be compiled and run (assuming they weren't disabled in configure) with: make check. Further details on running and extending unit tests can be found in /src/test/README.md.

There are also regression and integration tests, written in Python. These tests can be run (if the test dependencies are installed) with: test/functional/test_runner.py

The CI (Continuous Integration) systems make sure that every pull request is built for Windows, Linux, and macOS, and that unit/sanity tests are run automatically.

Manual Quality Assurance (QA) Testing

Changes should be tested by somebody other than the developer who wrote the code. This is especially important for large or high-risk changes. It is useful to add a test plan to the pull request description if testing the changes is not straightforward.

Translations

Changes to translations as well as new translations can be submitted to Bitcoin Core's Transifex page.

Translations are periodically pulled from Transifex and merged into the git repository. See the translation process for details on how this works.

Important: We do not accept translation changes as GitHub pull requests because the next pull from Transifex would automatically overwrite them again.
