(Amiti Uttarwar)3997ab9154[test] Add test framework support to create outbound connections. (Amiti Uttarwar)5bc04e8837[rpc/net] Introduce addconnection to test outbounds & blockrelay (Amiti Uttarwar) Pull request description: The existing functional test framework uses the `addnode` RPC to spin up manual connections between bitcoind nodes. This limits our ability to add integration tests for our networking code, which often executes different code paths for different connection types. **This PR enables creating `outbound` & `block-relay-only` P2P connections in the functional tests.** This allows us to increase our p2p test coverage, since we can now verify expectations around these connection types. This builds out the [prototype](https://github.com/bitcoin/bitcoin/issues/14210#issuecomment-527421978) proposed by ajtowns in #14210. 🙌🏽 An overview of this branch: - introduces a new test-only RPC function `addconnection` which initiates opening an `outbound` or `block-relay-only` connection. (conceptually similar to `addnode` but for different connection types & restricted to regtest) - adds `test_framework` support so a mininode can open an `outbound`/`block-relay-only` connection to a `P2PInterface`/`P2PConnection`. - updates `p2p_blocksonly` tests to create a `block-relay-only` connection & verify expectations around transaction relay. - introduces `p2p_add_connections` test that checks the behaviors of the newly introduced `add_outbound_p2p_connection` test framework function. With these changes, there are many more behaviors that we can add integration tests for. The blocksonly updates is just one example. Huge props to ajtowns for conceiving the approach & providing me feedback as I've built out this branch. Also thank you to jnewbery for lots of thoughtful input along the way.

Bitcoin Core integration/staging tree
What is Bitcoin?
Bitcoin is an experimental digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin Core is the name of open source software which enables the use of this currency.
For more information, as well as an immediately usable, binary version of the Bitcoin Core software, see https://bitcoincore.org/en/download/, or read the original whitepaper.
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, that are run automatically on the build server.
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.
Translators should also subscribe to the mailing list.
