faafc35a77 doc: Clarify that -datacarriersize applies to the full raw scriptPubKey, not the data push (MarcoFalke)
55550e7fe7 test: Add -datacarriersize=2 tests (MarcoFalke)
Pull request description:
Clarify with a test that `-datacarriersize` applies to the serialized size of the scriptPubKey, not the size of the pushed data. So for example,
* `-datacarriersize=2` will reject a `raw(6a01aa)`, even though only one byte is pushed
* `-datacarriersize=0` (or `-datacarrier=0`) will reject a `raw(6a)`, even though no byte is pushed
* `-datacarriersize=0` (or `-datacarrier=0`) will reject a `raw(6a00)`, even though zero bytes are pushed

025fda0a76 fuzz: addrman, avoid `ConsumeDeserializable` when possible (brunoerg)
Pull request description:
Using specific functions like `ConsumeService`, `ConsumeAddress` and `ConsumeNetAddr` may be more effective than using `ConsumeDeserializable`. They always return some value while `ConsumeDeserializable` may return `std::nullopt`.
E.g.: In this part of the code, if `op_net_addr` is `std::nullopt`, we basically generated the addresses (if so) unnecessarily, because we won't be able to use them:
```cpp
std::vector<CAddress> addresses;
LIMITED_WHILE(fuzzed_data_provider.ConsumeBool(), 10000) {
const std::optional<CAddress> opt_address = ConsumeDeserializable<CAddress>(fuzzed_data_provider);
if (!opt_address) {
break;
}
addresses.push_back(*opt_address);
}
const std::optional<CNetAddr> opt_net_addr = ConsumeDeserializable<CNetAddr>(fuzzed_data_provider);
if (opt_net_addr) {
addr_man.Add(addresses, *opt_net_addr, std::chrono::seconds{ConsumeTime(fuzzed_data_provider, 0, 100000000)});
}
```
Also, if we are not calling `Add` effectively, it would also be affect other functions that may "depend" on it.

Using `py.exe` launcher might by fragile depending on how Python was
installed. Specifying the Python version explicitly fixes test errors

Rather than using a bloom filter to track announced invs, simply allow
a peer to request any tx that entered the mempool prior to the last INV
message we sent them. This also obsoletes the UNCONDITIONAL_RELAY_DELAY.

Instead of recursively calling `UnserializeMany` and peeling off one
argument at a time, use a fold expression. This simplifies the code,
makes it most likely faster because it reduces the number of function
calls, and compiles faster because there are fewer template
instantiations.

Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/27140
Adds test coverage for https://github.com/bitcoin/bitcoin/pull/20516 to ensure that https://github.com/bitcoin/bitcoin/issues/20511 is completed and may be closed.
This PR adds a test case to `feature_anchors.py` where an onion v3 address is set as a blocks-only relay peer and then shutdown, ensuring that the address is saved to anchors.dat in addrv2 format. We then ensure that bitcoin attempts to reconnect to that anchor address on restart.
To compute the addrv2 serialization of the onion v3 address, I added logic to `CAddress` in `messages.py`. This new logic is covered by extending `p2p_addrv2_relay.py` to include an onion v3 address. Future work will be adding coverage for ipv6, torv2 and cjdns in these modules and also `feature_proxy.py`
Also includes de/serialization unit test for `CAddress` in test framework.

2c0c6f4477 test: dedup file hashing using `sha256sum_file` helper (Sebastian Falbesoner)
Pull request description:
Rather than doing the open/read/hash-steps manually in the affected functional tests, we can just use the `sha256sum_file` helper from the utils module instead.
Note that for the tool_wallet.py test, the used hash is changed from sha1 to sha256, but as the only purpose is to detect file content changes, this doesn't matter. Also, the optimization using `memoryview` is overkill here, as the opened file has only a size of 24KiB and determining the hash via the helper doesn't take longer than a few hundred micro-seconds on my machine.

Wrap leveldb::DestroyDB in a helper function without exposing
leveldb-specifics.
Also, add missing optional include.
The context of this commit is an effort to decouple the dbwrapper header
file from leveldb includes. To this end, the includes are moved to the
dbwrapper implementation file. This is done as part of the kernel
project to reduce the number of required includes for users of the
kernel.

Pull request description:

In the consistency check, it's not enough to check that our address/port is unique, only the combination of source and target must be unique. Otherwise, the OS may reuse ports for connections to different `-addrbind`, which was happening in the failed runs.
While at it, the second commit cleans up duplicate `getaddr` messages in `p2p_getaddr_caching.py` that do nothing but generate `Ignoring repeated "getaddr"` log messages (and cleans up some whitespace the python linter complains about).

Pull request description:
This PR proposes a clean up of the relationship between block storage and the chainstate objects, by moving the decision of whether to store a block on disk to something that is not chainstate-specific. Philosophically, the decision of whether to store a block on disk is related to validation rules that do not require any UTXO state; for anti-DoS reasons we were using some chainstate-specific heuristics, and those have been reworked here to achieve the proposed separation.
This PR also fixes a bug in how a chainstate's `setBlockIndexCandidates` was being initialized; it should always have all the HAVE_DATA block index entries that have more work than the chain tip. During startup, we were not fully populating `setBlockIndexCandidates` in some scenarios involving multiple chainstates.
Further, this PR establishes a concept that whenever we have 2 chainstates, that we always know the snapshotted chain's base block and the base block's hash must be an element of our block index. Given that, we can establish a new invariant that the background validation chainstate only needs to consider blocks leading to that snapshotted block entry as potential candidates for its tip. As a followup I would imagine that when writing net_processing logic to download blocks for the background chainstate, that we would use this concept to only download blocks towards the snapshotted entry as well.
