fada66fc2c Disallow copies of CChain (MarcoFalke)
Pull request description:
Creating a copy of the chain is not a valid use case in normal operation. Also, it massively degrades performance.
However, it seems to be a mistake that no one looks out for during review:
* https://github.com/bitcoin/bitcoin/pull/22677#discussion_r760400537
Fix this by disallowing it.

---
Currently, `BlockManager::LoadBlockIndex` adds all blocks that have downloaded transactions to the active chain state's `setBlockIndexCandidates` set, ignoring the background chain state.
This PR changes ChainstateManager::LoadBlockIndex to update `setBlockIndexCandidates` in the background chain, not just the active chain. In the active chain, the same blocks are added as before. In the background chain, only blocks that have actually been validated, not blocks marked assumed-valid are added so the background chain will continue to download and validate assumed-valid blocks.

caac999ff0 refactor: remove dependence on AddrManTest (josibake)
f961c477b5 refactor: check Good() in tried_collisions test (josibake)
207f1c825c refactor: make AddrMan::Good return bool (josibake)
Pull request description:
Previously, the `addrman_tried_collisions` test behaved in the following way:
1. add an address to addrman
2. attempt to move the new address to the tried table (using `AddrMan.Good()`)
3. verify that `num_addrs` matched `size()` to check for collisions in the new table
`AddrMan.size()`, however, returns the number of unique address in addrman, regardless of whether they are in new or tried. This means the test would still pass for addresses where a collision did occur in the tried table. After 3 collisions in the tried table, there would eventually be a collision in the new table when trying to add a new address, which was then detected by checking `num_addrs - collisions == size()`.
While the collision in the new table was caused by a collision in the tried table, the test is misleading as it's not directly testing for collisions in the tried table and misses 3 collisions before identifying a collision in the new table.
### solution
To more directly test the tried table, I refactored `AddrMan::Good()` to return a boolean after successfully adding an address to the tried table. This makes the test much cleaner by first adding an address to new, calling `Good` to move it to the tried table, and checking if it was successful or not. It is worth noting there are other reasons, aside from collisions, which will cause `Good` to return false. That being said, this is an improvement over the previous testing methodology.
Additionally, having `Good()` return a boolean is useful outside of testing as it allows the caller to handle the case where `Good` is unable to move the entry to the tried table (e.g a063647413/src/rpc/net.cpp (L945)).
### followup
As a follow up to this PR, I plan to look at the following places `Good()` is called and see if it makes sense to handle the case where it is unable to add an entry to tried:
* a063647413/src/rpc/net.cpp (L945)
* a063647413/src/net.cpp (L2067)
* a063647413/src/net_processing.cpp (L2708)

eaf6be0114 [net processing] Do not request transaction relay from feeler connections (John Newbery)
0220b834b1 [test] Add testing for outbound feeler connections (John Newbery)
Pull request description:
Feelers are short-lived connections used to test the viability of peers. The bitcoind node will periodically open feeler connections to addresses in its addrman, wait for a `version` message from the peer, and then close the connection.
Currently, we set `fRelay` to `1` in the `version` message for feeler connections, indicating that we want the peer to relay transactions to us. However, we close the connection immediately on receipt of the `version` message, and so never process any incoming transaction announcements. This PR changes that behaviour to instead set `fRelay` to `0` indicating that we do not wish to receive transaction announcements from the peer.
This PR also extends the `addconnection` RPC to allow creating outbound feeler connections from the node to the test framework, and a test to verify that the node sets `fRelay` to `0` in the `version` message to feeler connections.

Rather than try to infer a collision by checking `AddrMan::size`,
check whether or not moving to the tried table was successful by
checking the output from `AddrMan::Good`
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.

Ensure that blocks past the snapshot base block (i.e. the end of the
assumed-valid region of the chain) are not included in
setBlockIndexCandidates for the background validation chainstate. These
blocks, while fully validated and lacking the BLOCK_ASSUMED_VALID flag,
*rely* on blocks which are assumed-valid, and so shouldn't be added to
the IBD chainstate.
Co-authored-by: Russ Yanofsky <russ@yanofsky.org>
Avoid modifying the genesis block index entry during snapshot load. This
is because, in a future change that fixes LoadBlockIndex for UTXO
snapshots, we detect block index entries that are reliant on
assumed-valid ancestors and treat them specially.
Since the genesis block doesn't have BLOCK_VALID_SCRIPTS, it would be
erroneously marked BLOCK_ASSUMED_VALID during snapshot load if we didn't
skip it here. This would cause a "setBlockIndexCandidates() empty"
assertion to be tripped since all block index entries would be marked
assume-valid due to genesis, which is never re-validated.
There's probably no good reason to modify the genesis block index entry
during snapshot load anyway...

9600ea0145 test: Add edge case of pruning up to index height (Martin Zumsande)
698c524698 index: Fix backwards search for bestblock (Martin Zumsande)
Pull request description:
This PR attempts to fix an intermittent Init issue encountered during the stress testing of #23289, which relates to the pruning-compatible filter reconstruction logic introduced in #15946.
The problem would occur when the node starts with `-txindex=1` but `ThreadSync` is interrupted after it sets `m_best_block_index` to Genesis, and before it gets do any further work.
In that case, during the next restart of the node, an Init error would be thrown because `BaseIndex::Init()` tries to backtrack from the tip to the last block which has been successfully indexed (here: Genesis), but the backtracking logic didn't work properly in this case:
The loop
`while (block_to_test && block->pprev && (block->pprev->nStatus & BLOCK_HAVE_DATA))` checks if a predecessor exists **before** performing the check `block_to_test == block` and then possbily setting `prune_violation = false`
If `block_to_test` and `block` are the Genesis block this check will not be reached because `block->pprev` does not exist.
To reproduce this bug on regtest:
1) start a node with a fresh datadir using `-txindex=1` (or any other index)
2) stop and restart without any index
3) mine a block
3) stop and restart again with the index enabled
->InitError `Error: txindex best block of the index goes beyond pruned data. (...)`
Fix this by requiring that we have the data for the block of the current iteration `block` (instead of requiring it for the predecessor `block->pprev`)
That way, the check for `block_to_test == block` is also reached when `block_to_test` is the Genesis block.
No longer requiring the data of `block->pprev` also means that we can now prune up to `m_best_block_index` height without requiring a reindex (one block more than before). I added this edge case to `feature_blockfilterindex_prune.py`, the new version should fail on master.

Partial code review ACK 9600ea0145 for the code change, not the test changes. (Test changes are indirect and little over my head.) It seems obvious that previous code `prune_violation = true, while (block->pprev)` would incorrectly detect a prune violation at the genesis block, and the fix here make sense and looks correct.
