J. van der Laan) 9b29d5df7fc555eaea42029f334f2995c6ccde3d contrib: Add explicit port numbers for testnet seeds (W. J. van der Laan) 2a257de113fd31539b68c28c47ef94f257b6e427 contrib: Add a few TorV3 seed nodes (W. J. van der Laan) 06030f7a42dea33c5120504dcd99d1714883f271 contrib: generate-seeds.py generates output in BIP155 format (W. J. van der Laan) Pull request description: Closes #20239 and mitigates my node's problem in #21351. - Add a few hardcoded seeds for TorV3 - As the [bitcoin-seeder](https://github.com/sipa/bitcoin-seeder) doesn't collect TorV3 addresses yet, I have extracted these from my own node using [a script](https://gist.github.com/laanwj/b3d7b01ef61ce07c2eff0a72a6b90183) and added them manually. This is intended to be a temporary stop gap until 22.0's seeds update. - Change hardcoded seeds to variable length BIP155 binary format. - It is stored as a single serialized blob in a byte array, instead of pseudo-IPv6 address slots. This is more flexible and, assuming most of the list is IPv4, more compact. - Only the (networkID, addr, port) subset (CService). Services and time are construed on the fly as before. - Change input format for `nodes_*.txt`. - Drop legacy `0xAABBCCDD` format for IPv4. It is never generated by `makeseeds.py`. - Stop interpreting lack of port as default port, interpret it as 'no port', to accomodate I2P and other port-less protocols (not handled in this PR). An explicit port is always generated by `makeseeds.py` so in practice this makes no difference right now. A follow-up to this PR could do the same for I2P.

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.

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.
