65332b1178[addrman] Remove RemoveInvalid() (John Newbery) Pull request description: PRs #22179 and #22112 (EDIT: later reverted in #22497) added hotfix code to addrman to remove invalid addresses and mutate the ports of I2P entries after entering into addrman. Those hotfixes included at least two addrman data corruption bugs: - #22467 (Assertion `nRndPos1 < vRandom.size() && nRndPos2 < vRandom.size()' failed) - #22470 (Changing I2P ports in addrman may wronly skip some entries from "new" buckets) Hotfixing addrman is inherently dangerous. There are many members that have implicit assumptions on each others' state, and mutating those directly can lead to violating addrman's internal invariants. Instead of trying to hotfix addrman, just don't insert any invalid addresses. For now, those are addresses which fail `CNetAddr::IsValid()`. ACKs for top commit: sipa: utACK65332b1178. I tried to reason through scenarios that could introduce inconsistencies with this code, but can't find any. fanquake: ACK65332b1178- Skipping the addition of invalid addresses (this code was initially added for Tor addrs) rather than adding all the invalids then removing them all when finishing unserializing seems like an improvement. Especially if it can be achieved with less code. Tree-SHA512: 023113764cb475572f15da7bf9824b62b79e10a7e359af2eee59017df354348d2aeed88de0fd4ad7a9f89a0dad10827f99d70af6f1cb20abb0eca2714689c8d7

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

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.
