Merge bitcoin/bitcoin#28428: Hard-code version number value for CBlockLocator and CDiskBlockIndex 
e73d2a8018 refactor: remove clientversion include from dbwrapper.h (Cory Fields)
4240a082b8 refactor: Use DataStream now that version/type are unused (Cory Fields)
f15f790618 Remove version/hashing options from CBlockLocator/CDiskBlockIndex (Cory Fields)

Pull request description:

  This is also a much simpler replacement for #28327.

  There are version fields in `CBlockLocator` and `CDiskBlockIndex` that have always been written but discarded when read.

  I intended to convert them to use SerParams as introduced by #25284, which [ended up looking like this](3e3af45165). However because we don't currently have any definition of what a hash value would mean for either one of those, and we've never assigned the version field any meaning, I think it's better to just not worry about them.

  If we ever need to assign meaning in the future, we can introduce `SerParams` as was done for `CAddress`.

  As for the dummy values chosen:

  `CDiskBlockIndex::DUMMY_VERSION` was easy as the highest ever client version, and I don't expect any objection there.

  `CBlockLocator::DUMMY_VERSION` is hard-coded to the higest _PROTOCOL_ version ever used. This is to avoid a sudden bump that would be visible on the network if CLIENT_VERSION were used instead. In the future, if we ever need to use the value, we can discard anything in the CLIENT_VERSION range (for a few years as needed), as it's quite a bit higher.

  While reviewing, I suggest looking at the throwaway `SerParams` commit above as it shows where the call-sites are. I believe that should be enough to convince one's self that hashing is never used.

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.
