Merge #17681: wallet: Keep inactive seeds after sethdseed and derive keys from them as needed 
1ed52fbb4d Remove IBD check in sethdseed (Andrew Chow)
b1810a145a Test that keys from inactive seeds are generated (Andrew Chow)
c93082ece4 Generate new keys for inactive seeds after marking used (Andrew Chow)
45f2f6a0e8 Determine inactive HD seeds from key metadata and track them in LegacyScriptPubKeyMan (Andrew Chow)
b59b4504ab have GenerateNewKey and DeriveNewChildKey take a CHDChain as an argument (Andrew Chow)

Pull request description:

  Largely implements the suggestion from https://github.com/bitcoin/bitcoin/pull/17484#issuecomment-560845316.

  After `sethdseed` is called, the CHDChain for the old seed is kept in the wallet. It is kept on the file as a new `inactivehdseed` record and in memory in a map `m_inactive_hd_seeds`. In `LegacyScriptPubKeyMan::MarkUnusedAddresses` we check each used key's metadata for whether it was derived from an inactive seed. If it is, we then check to see how many keys after that key were derived from the inactive seed. If that number does not match the keypool parameter, we derive more keys from the inactive seed until it does match. This way we won't miss transactions belonging to keys outside of the range of the keypool initially.

  The indexes and internal-ness of a key is gotten by checking it's key origin data.

  Because of this change, we no longer need to wait for IBD to finish before `sethdseed` can work so that check is also removed.

  A test case for this is added as well which fails on master.

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 is not guaranteed to be completely stable. Tags are created regularly to indicate new official, stable release versions of Bitcoin Core.

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 Travis CI system makes 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.
