cdaab90662a54e331de0e49a89596bbb94a8ac45 Add test for addrman consistency check on restart with asmap (Jon Atack) 869f136816c6900ce84bc4b5a9c93c0deab85193 Add test for rpc addpeeraddress with "tried" argument (Jon Atack) ef242f52137f2a79a739447251d7759bd4705be0 Allow passing "tried" to rpc addpeeraddress to call CAddrMan::Good() (Jon Atack) Pull request description: This pull adds a `tried` argument to RPC addpeeraddress and a regression test for the recent addrman/asmap changes and issue. PR #22697 introduced a reproducible bug in commit 181a1207 that fails addrman consistency checks and causes it to significantly lose peer entries when the `-asmap` configuration option is used. The issue occurs upon bitcoind restart due to an initialization order change in `src/init.cpp` in that commit, whereby CAddrman asmap is set after deserializing `peers.dat`, rather than before. Issue reported on the `#bitcoin-core-dev` IRC channel starting at https://www.erisian.com.au/bitcoin-core-dev/log-2021-08-23.html#l-263. ``` addrman lost 22813 new and 2 tried addresses due to collisions or invalid addresses ADDRMAN CONSISTENCY CHECK FAILED!!! err=-17 bitcoind: ./addrman.h:707: void CAddrMan::Check() const: Assertion `false' failed. Aborted ``` How to reproduce: - `git checkout 181a1207`, build, and launch bitcoind with the `-asmap` and `-checkaddrman=1` configuration options enabled - restart bitcoind - bitcoind aborts on the second call to the addrman consistency checks in `CAddrMan::Check()` How to test this pull: - `git checkout 181a1207`, cherry pick the first commit of this branch, build, git checkout this branch, run `test/functional/rpc_net.py`, which should pass, and then run `test/functional/feature_asmap.py`, which should fail with the following output: ``` AssertionError: Unexpected stderr bitcoind: ./addrman.h:739: void CAddrMan::Check() const: Assertion `false' failed. ``` ACKs for top commit: jnewbery: utACK cdaab90662a54e331de0e49a89596bbb94a8ac45 mzumsande: re-ACK cdaab90662a54e331de0e49a89596bbb94a8ac45 (based on code review of diff to d586817) vasild: ACK cdaab90662a54e331de0e49a89596bbb94a8ac45 Tree-SHA512: 0251a18fea629b62486fc907d7ab0e96c6df6fadb9e4d62cff018bc681afb6ac31e0e7258809c0a88f91e4a36c4fb0b16ed294ce47ef30585217de89c3342399

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.
