a5986e82ddrefactor: Remove CAddressBookData::destdata (Ryan Ofsky)5938ad0bdbwallet: Add DatabaseBatch::ErasePrefix method (Ryan Ofsky) Pull request description: This is cleanup that doesn't change external behavior. Benefits of the cleanup are: - Removes awkward `StringMap` intermediate representation for wallet address metadata. - Simplifies `CWallet`, deals with used address and received request serialization in `walletdb.cpp` instead of higher level wallet code - Adds test coverage and documentation This PR doesn't change externally observable behavior. Internally, the only change in behavior is that `EraseDestData` deletes rows directly from the database because they are no longer stored in memory. This is more direct and efficient because it uses a single lookup and scan instead of multiple lookups. Motivation for this cleanup is making changes like #18550, #18192, #13756 easier to reason about and less likely to result in unintended behavior and bugs --- This PR is a rebased copy of #18608. For some reason that PR is locked and couldn't be reopened or commented on. This PR is an alternative to #27215 with differences described in https://github.com/bitcoin/bitcoin/pull/27215#pullrequestreview-1329028143 ACKs for top commit: achow101: ACKa5986e82ddfurszy: Code ACKa5986e82Tree-SHA512: 6bd3e402f1f60263fbd433760bdc29d04175ddaf8307207c4a67d59f6cffa732e176ba57886e02926f7a1615dce0ed9cda36c8cbc6430aa8e5b56934c23f3fe7
Bitcoin Core integration/staging tree
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.
