2022-02-25p2p: Avoid InitError when downgrading peers.datjunderw
fixes #24188 When downgrading, a peers.dat with a future version that has a minimum required version larger than the downgraded version would cause an InitError. This commit changes this behavior to overwrite the existing peers.dat with a new empty one, while creating a backup in peers.dat.bak.

This includes the following steps: * Adding a test-only function `FindAddressEntry()` to the public addrman interface which returns info about an address in addrman (e.g. bucket, position, whethe the address is in new or tried). Obviously we want to do this sparingly, but I think a single test-only function is ok (which could also be useful elsewhere, e.g. in fuzz tests). * Removal of the `AddrManTest` subclass which would reach into AddrMan's internals, using `AddrMan` instead * Removal of tests for internal helper functions that are not publicly exposed (these are still tested indirectly via the public functions calling them). * Additional tests for previously untested features such as multiplicity in the new tables, that can be tested with the help of `FindAddressEntry()`. All in all, this PR increases the unit test coverage of AddrMan by a bit.

2021-12-28addrman: Introduce a test-only function to lookup addressesAmiti Uttarwar
Co-Authored-By: Martin Zumsande <mzumsande@gmail.com>
2021-12-14refactor: make AddrMan::Good return booljosibake
If AddrMan::Good is unable to add an entry to tried (for a number of reasons), return false. This makes it much easier and cleaner to directly test for tried collisions. It also allows anyone calling Good() to handle the case where adding an address to tried is unsuccessful. Update docs to doxygen style.
2021-11-09[addrman] Remove AddrMan friendsJohn Newbery
AddrMan's friends both inherit from AddrMan, so just make the private member protected and remove the friends.
2021-10-28[addrman] Add Add_() inner function, fix Add() return semanticsJohn Newbery
Previously, Add() would return true if the function created a new AddressInfo object, even if that object could not be successfully entered into the new table and was deleted. That would happen if the new table position was already taken and the existing entry could not be removed. Instead, return true if the new AddressInfo object is successfully entered into the new table. This fixes a bug in the "Added %i addresses" log, which would not always accurately log how many addresses had been added. p2p_addrv2_relay.py and p2p_addr_relay.py need to be updated since they were incorrectly asserting on the buggy log (assuming that addresses are added to addrman, when there could in fact be new table position collisions that prevent some of those address records from being added).
2021-10-28[addrman] Add doxygen comment to AddrMan::Add()John Newbery
Does not document the return value since we're going to fix the semantics in a future commit.

CAddrInfo objects are an implementation detail of how AddrMan manages and adds metadata to different records. Encapsulate this logic by updating Select & SelectTriedCollision to return the additional info that the callers need.
2021-09-28[addrman] Introduce CAddrMan::Impl to encapsulate addrman implementation.Amiti Uttarwar
Introduce the pimpl pattern for CAddrMan to separate the implementation details from the externally used object representation. This reduces compile-time dependencies and conceptually clarifies AddrMan's interface from the implementation specifics. Since the unit & fuzz tests currently rely on accessing CAddrMan internals, this commit introduces addrman_impl.h, which is exclusively imported by addrman.cpp and test files.

The first commit restores the correct initialization order. The remaining commits make `CAddrMan::m_asmap` usage safer: - don't reach into `CAddrMan`'s internal data from `CConnMan` - set `m_asmap` in the initializer list and make it const - make `m_asmap` private, and access it (as a reference to const) from a getter. This ensures that peers.dat deserialization must happen after setting m_asmap, since m_asmap is set during CAddrMan construction.

2021-08-12[addrman] Make addrman consistency checks a runtime optionJohn Newbery
Currently addrman consistency checks are a compile time option, and are not enabled in our CI. It's unlikely anyone is running these consistency checks. Make them a runtime option instead, where users can enable addrman consistency checks every n operations (similar to mempool tests). Update the addrman unit tests to do internal consistency checks every 100 operations (checking on every operations causes the test runtime to increase by several seconds). Also assert on a failed addrman consistency check to terminate program execution.
2021-08-05[tests] Make deterministic addrman use nKey = 1John Newbery
addrman_tests fail when consistency checks are enabled, since the tests set the deterministic test addrman's nKey value to zero, which is an invalid value. Change this so that deterministic addrman's nKey value is set to 1. This requires updating a few tests that are using magic values derived from nKey being set to 0.

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()`.
