ad75b147b5 test: scale IPC mining wait timeouts by timeout_factor (Enoch Azariah)
e7a918b69a test: verify IPC error handling for invalid coinbase (Enoch Azariah)
63684d6922 test: move make_mining_ctx to ipc_util.py (Enoch Azariah)
4ada575d6c test: verify createNewBlock wakes promptly when tip advances (Enoch Azariah)

Pull request description:

  This is a follow-up to implement a couple of test improvements discussed in recent IPC PRs and issues.

  - adds a test to `interface_ipc_mining.py` to verify that `createNewBlock` wakes up immediately when the tip advances, rather than waiting for the cooldown timer to expire (https://github.com/bitcoin/bitcoin/pull/34184#discussion_r2842239399).
  - moves `make_mining_ctx` into `ipc_util.py` so it can be reused across the IPC tests instead of duplicating the setup code (https://github.com/bitcoin/bitcoin/pull/34422#discussion_r2852445430).
  - adds a test case to verify that providing an invalid coinbase to `submitSolution` returns a remote exception instead of crashing the node, closing the loop on the issue reported in #33341.
  - scales IPC wait timeouts using the test suite's `timeout_factor` to prevent spurious failures in heavily loaded CI environments, capping extended waits to avoid test runner hangs (bitcoin-core/libmultiprocess#253 (comment)).

  Closes #33341.

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/license/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 during the generation of the build system) with: ctest. 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: build/test/functional/test_runner.py (assuming build is your build directory).

The CI (Continuous Integration) systems make sure that every pull request is tested on Windows, Linux, and macOS. The CI must pass on all commits before merge to avoid unrelated CI failures on new pull requests.

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.
