8f14fc86225d8fe77353f61ebd6b0bdda8d13aa9 test: cover fastprune with excessive block size (Matthew Zipkin)
271c23e87f61276d7acab74e115b25a35144c8b4 blockstorage: Adjust fastprune limit if block exceeds blockfile size (Martin Zumsande)
Pull request description:
The debug-only `-fastprune` option used in several tests is not always safe to use:
If a `-fastprune` node receives a block larger than the maximum blockfile size of `64kb` bad things happen: The while loop in `BlockManager::FindBlockPos` never terminates, and the node runs oom because memory for `m_blockfile_info` is allocated in each iteration of the loop.
The same would happen if a naive user used `-fastprune` on anything other than regtest (so this can be tested by syncing on signet for example, the first block that crashes the node is at height 2232).
Change the approach by raising the blockfile size to the size of the block, if that block otherwise wouldn't fit (idea by TheCharlatan).

Pull request description:
Since #27483 was merged the `modinv()` body is just one line calling pythons own implementation of `pow()`. We can just remove the function as it doesn't seem to add any value. Additionally the comment in the function is now outdated and the test is only testing two ways of doing modular inverse but both using python's `pow()` function.

ce50acc54fa313a92d48ed03e46ce8aabcf267e5 rpc: scanblocks, do not traverse the whole chain block by block (furszy)
Pull request description:
Coming from https://github.com/bitcoin/bitcoin/pull/23549#pullrequestreview-1105712566
The current `scanblocks` flow walks-through every block in the active chain
until hits the chain tip or processes 10k blocks, then calls `lookupFilterRange`
function to obtain all filters from that particular range.
This is only done to obtain the heights range to look up the block
filters. Which is unneeded.
As `scanblocks` only lookup block filters in the active chain, we can
directly calculate the lookup range heights, by using the chain tip,
without requiring to traverse the chain block by block.

7bffec6715a75bb2c8631177d39f984aabc656ba bumpfee: enable send coins back to yourself (furszy)
Pull request description:
Simple example:
1) User_1 sends 0.1 btc to user_2 on a low fee transaction.
2) After few hours, the tx is still in the mempool, user_2
is not interested anymore, so user_1 decides to cancel
it by sending coins back to himself.
3) User_1 has the bright idea of opening the explorer and
copy the change output address of the transaction. Then
call bumpfee providing such output (in the "outputs" arg).
Currently, this is not possible. The wallet fails with
"Unable to create transaction. Transaction must have at least
one recipient" error.
The error reason is because we discard the provided output
from the recipients list and set it inside the coin control
so the process adds it later (when the change is calculated).
But.. there is no later if the tx has no outputs.

5938ad0bdb013953861c7cd15a95f00998a06f44 wallet: Add DatabaseBatch::ErasePrefix method (Ryan Ofsky)
Pull request description:
This is cleanup that doesn't change external behavior. Benefits of the cleanup are:
- Removes awkward `StringMap` intermediate representation for wallet address metadata.
- Simplifies `CWallet`, deals with used address and received request serialization in `walletdb.cpp` instead of higher level wallet code
- Adds test coverage and documentation
This PR doesn't change externally observable behavior. Internally, the only change in behavior is that `EraseDestData` deletes rows directly from the database because they are no longer stored in memory. This is more direct and efficient because it uses a single lookup and scan instead of multiple lookups.
Motivation for this cleanup is making changes like #18550, #18192, #13756 easier to reason about and less likely to result in unintended behavior and bugs

To tell the user whether the process was aborted or not.
Plus, as the process can be aborted prior to the end range,
have also changed the "to_height" result value to return the
last scanned block instead of the end range block.

hits the chain tip or processes 10k blocks, then calls

ac463e87df728689701810c3961155c49fdc5b31 [test util] mock mempool minimum feerate (glozow)
Pull request description:
Part of package relay, see #27463.
Note that this still allows packages to bump transactions that are below the dynamic mempool minimum feerate, which means this still solves the "mempool is congested and my presigned 1sat/vB tx is screwed" problem for all transactions.
On master, the package policy (only accessible through regtest-only RPC submitpackage) allows 0-fee (or otherwise below min relay feerate) transactions if they are bumped by a child. However, with default package limits, we don't yet have a DoS-resistant way of ensuring these transactions remain bumped throughout their time in the mempool. Primarily, the fee-bumping child may later be replaced by another transaction that doesn't bump the parent(s). The parent(s) could potentially stay bumped by other transactions, but not enough to ever be selected by the `BlockAssembler` (due to `blockmintxfee`).
For example, (tested [here](https://github.com/glozow/bitcoin/commits/26933-motivation)):
- The mempool accepts 24 below-minrelayfeerate transactions ("0-fee parents"), all bumped by a single high-fee transaction ("the fee-bumping child"). The fee-bumping child also spends a confirmed UTXO.
- Two additional children are added to each 0-fee parent. These children each pay a feerate slightly above the minimum relay feerate (e.g. 1.9sat/vB) such that, for each 0-fee parent, the total fees of its two children divided by the total size of the children and parent is above the minimum relay feerate.
- If a block template is built now, all transactions would be selected.
- A transaction replaces the the fee-bumping child, spending only the confirmed UTXO and not any of the outputs from the 0-fee parents.
- The 0-fee parents now each have 2 children. Their descendant feerates are above minrelayfeerate, which means that they remain in the mempool, even if the mempool evicts all below-minrelayfeerate packages.
- If a block template is built now, none of the 0-fee parents or their children would be selected.
- Even more low-feerate descendants can be added to these below-minrelayfeerate packages and they will not be evicted until they expire or the mempool reaches capacity.
Unless we have a DoS-resistant way of ensuring package CPFP-bumped transactions are always bumped, allowing package CPFP to bump below-minrelayfeerate transactions can result in these problematic situations. See #27018 which proposes a partial solution with some limitations, and contains discussion about potential improvements to eviction strategy. While no adequate solution exists, for now, avoid these situations by requiring all transactions to meet min relay feerate.

These routines look fancy, but do nothing more than converting between
byte objects of length 32 to/from integers in little endian byte order
and can be replaced by simple one-liners, using the int.{from,to}_bytes
methods (available since Python 3.2).

a5b4883fb43d01bfef1244df62c64bf8691ca63a rpc: extract psbt updating logic into ProcessPSBT (ishaanam)
Pull request description:
Previously the `utxoupdatepsbt` RPC, added in #13932, only updated the inputs spending segwit outputs with the `witness_utxo`, because the full transaction is needed for legacy inputs. Before this RPC looked for just the utxos in the utxo set and the mempool. This PR makes it so that if the user has txindex enabled, then the full transaction is looked for there for all inputs. If it is not found in the txindex or txindex isn't enabled, then the mempool is checked for the full transaction. If the transaction an input is spending from is still not found at that point, then the utxo set is searched and the inputs spending segwit outputs are updated with just the utxo.

63c0c4ff10b2f6ed8510ef372a5b1f6a6494b179 depends: reuse _config_opts for CMake options (Cory Fields)
Pull request description:
Context: I'm [currently experimenting with building our depends with CMake when possible](https://github.com/theuni/bitcoin/commits/depends-cmake) as part of our future transition to CMake. Specifically zmq, libevent, libnatpmp, and miniupnpc all have existing CMake buildsystems. Building them with CMake will allow us to drop several deps that we currently have (autoconf, automake, pkg-config, etc) which would be unfortunate to carry over after the switch-over.
But that's not relevant for this PR. This is just a very simple change that makes the above work easier to experiment with as it [adds a needed feature for CMake packages](5733dc2000 (diff-e6ed342a25092e0a6d0308e0bfd826044578847132cc6726ac4afa2ca767b61aR20)). It's a no-op for the current builds.
---
From commit description:
This will allow us to use the existing machinery for filtering by arch, os, debug/release, etc.
For example, the following becomes possible for libevent when building with CMake:
`$(package)_config_opts_release=-DEVENT__DISABLE_DEBUG_MODE`
Now the define is only set when not building depends with DEBUG=1

be55f545d53d44fdcf2d8ae802e9eae551d120c6 move-only: Extract common/args and common/config.cpp from util/system (TheCharlatan)
Pull request description:
This pull request is part of the `libbitcoinkernel` project https://github.com/bitcoin/bitcoin/issues/24303https://github.com/bitcoin/bitcoin/projects/18 and more specifically its "Step 2: Decouple most non-consensus code from libbitcoinkernel". It is part of a series of patches splitting up the `util/system` files. Its preceding pull request is https://github.com/bitcoin/bitcoin/pull/27254.
The pull request contains an extraction of ArgsManager related functions from util/system into their own common/ file.
The background of this commit is an ongoing effort to decouple the libbitcoinkernel library from the ArgsManager. The ArgsManager belongs into the common library, since the kernel library should not depend on it. See [doc/design/libraries.md](https://github.com/bitcoin/bitcoin/blob/master/doc/design/libraries.md) for more information on this rationale.

9836c76ae048698e4f7dab21e3be37313e8392ae net: add `GetMappedAS` in `CConnman` (brunoerg)
Pull request description:
When using `-asmap`, you can check the ASN assigned to the peers only with the RPC command `getpeerinfo` (check `mapped_as` field), however, it's not possible to check it in logs (e.g. see in logs the ASN of the peers when a new outbound peer has been connected). This PR includes the peers' ASN in debug output when using `-asmap`.
Obs: Open this primarily to chase some Concept ACK, I've been using this on my node to facilitate to track the peers' ASN especially when reading the logs.

1284223691127e76135a46d251c52416104f0ff1 wallet: refactor coin selection algos to return util::Result (furszy)
Pull request description:
Coming from the following comment https://github.com/bitcoin/bitcoin/pull/25729#discussion_r1029324367.
The reason why we are adding hundreds of UTXO from different sources when the target
amount is covered only by one of them is because only SRD returns a usable result.
Context:
In the test, we create 1515 UTXOs with 0.033 BTC each, and 1 UTXO with 50 BTC. Then
perform Coin Selection to fund 49.5 BTC.
As the selection of the 1515 small UTXOs exceeds the max allowed tx size, the
expectation here is to receive a selection result that only contain the big UTXO.
Which is not happening for the following reason:
Knapsack returns a result that exceeds the max allowed transaction size, when
it should return the closest utxo above the target, so we fallback to SRD who
selects coins randomly up until the target is met. So we end up with a selection
result with lot more coins than what is needed.

Pull request description:
A memory resource similar to `std::pmr::unsynchronized_pool_resource`, but optimized for node-based containers. The goal is to be able to cache more coins with the same memory usage, and allocate/deallocate faster.
This is a reimplementation of #22702. The goal was to implement it in a way that is simpler to review & test
* There is now a generic `PoolResource` for allocating/deallocating memory. This has practically the same API as `std::pmr::memory_resource`. (Unfortunately I cannot use std::pmr because libc++ simply doesn't implement that API).
* Thanks to sipa there is now a fuzzer for PoolResource! On a fast machine I ran it for ~770 million executions without finding any issue.
* The estimation of the correct node size is now gone, PoolResource now has multiple pools and just needs to be created large enough to have space for the unordered_map nodes.
I ran benchmarks with #22702, mergebase, and this PR. Frequency locked Intel i7-8700, clang++ 13.0.1 to reindex up to block 690000.
```sh
bitcoind -dbcache=5000 -assumevalid=00000000000000000002a23d6df20eecec15b21d32c75833cce28f113de888b7 -reindex-chainstate -printtoconsole=0 -stopatheight=690000
```
The performance is practically identical with #22702, just 0.4% slower. It's ~21% faster than master:
Note that on cache drops mergebase's memory doesnt go so far down because it does not free the `CCoinsMap` bucket array.

Pull request description:
For the full context & motivation of this patch, see #27213
This is joint work with mzumsande.
This PR adds functionality to `AddrMan::Select` to enable callers to specify a network they are interested in.
Along the way, it refactors the function to deduplicate the logic, updates the local variables to match modern conventions, adds test coverage for both the new and existing `Select` logic, and adds bench tests for the worst case performance of both the new and existing `Select` logic.
This functionality is used in the parent PR.
