6e9f8bb050 rpc, tests: in `utxoupdatepsbt` also look for the transaction in the txindex (ishaanam)
a5b4883fb4 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.

Currently debug.log will show the wrong bitcoin.conf config file path when
bitcoind is invoked without -conf or -datadir arguments, and there's a default
bitcoin.conf file which specifies another datadir= location. When this happens,
the debug.log will include an incorrect "Config file:" line referring to a
bitcoin.conf file in the other datadir, instead of the referring to the actual
configuration file in the default datadir which was parsed.
The bad log print was reported and originally fixed in
https://github.com/bitcoin/bitcoin/pull/27303 by
Matthew Zipkin <pinheadmz@gmail.com>
This PR takes a slightly different approach to fixing the bug, trying to avoid
future bugs by not allowing the GetConfigFilePath function to be called before
the the configuration is parsed, and deleting GetConfigFile function which
could be confused with GetConfigFilePath. It also includes a test for the bug
which the original fix did not have.

Show an error on startup if a bitcoin datadir that is being used contains a
`bitcoin.conf` file that is ignored. There are two cases where this could
happen:
- One case reported in
https://github.com/bitcoin/bitcoin/issues/27246#issuecomment-1470006043
happens when a bitcoin.conf file in the default datadir (e.g.
$HOME/.bitcoin/bitcoin.conf) has a "datadir=/path" line that sets different
datadir containing a second bitcoin.conf file. Currently the second
bitcoin.conf file is ignored with no warning.
- Another way this could happen is if a -conf= command line argument points
to a configuration file with a "datadir=/path" line and that specified path
contains a bitcoin.conf file, which is currently ignored.
This change only adds an error message and doesn't change anything about way
settings are applied. It also doesn't trigger errors if there are redundant
-datadir or -conf settings pointing at the same configuration file, only if
they are pointing at different files and one file is being ignored.
be55f545d5 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.

0076bed45e logging: log ASN when using `-asmap` (brunoerg)
9836c76ae0 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.

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.

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.

In PR 27374, the semantics of the `setConnected` data structure in
CConnman::ThreadOpenConnections changed from the set of outbound peer
netgroups to those of outbound IPv4/6 peers only.
This commit updates a code comment in this regard about feeler connections and
updates the naming of `setConnected` to `outbound_ipv46_peer_netgroups` to
reflect its new role.
`evhttp_uri_parse` can return a nullptr, for example when the URI
contains invalid characters (e.g. "%").
`GetQueryParameterFromUri` passes the output of `evhttp_uri_parse`
straight into `evhttp_uri_get_query`, which means that anyone calling
a REST endpoint in which query parameters are used (e.g. `rest_headers`)
can cause a segfault.
This bugfix is designed to be minimal and without additional behaviour change.
Follow-up work should be done to resolve this in a more general and robust way,
so not every endpoint has to handle it individually.
Avoid adding transactions below min relay feerate because, even if they
were bumped through CPFP when entering the mempool, we do not have a
DoS-resistant way of ensuring they always remain bumped. In the future,
this rule can be relaxed (e.g. to allow packages to bump 0-fee
transactions) if we find a way to do so.
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 that 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.
d52fa1b0a5 tests: Make sure that bumpfee feerate checks work when replacing outputs (Andrew Chow)
be177c15a4 bumpfee: Check the correct feerate when replacing outputs (Andrew Chow)
Pull request description:
When replacing the outputs of a transaction during `bumpfee`, it is possible to accidentally create a transaction that will not be accepted into the mempool as it does not meet the incremental relay fee requirements. This occurs because the size estimation used for checking the provided feerate does not account for the replaced outputs; it instead uses the original outputs. When the replaced outputs is significantly different from the original, there can be a large difference in estimated transaction sizes that can make a transaction miss the absolute fee requirements for the incremental relay fee. Unfortunately we do not currently inform the user when the bumped transaction fails to relay, so they could use `bumpfee` and think the transaction has been bumped when it actually has not.
This issue is resolved by replacing the outputs before doing the size estimation, and also updating the feerate checker to use the actual fee values when calculating the required minimum fee.
Also added a test for this scenario.

b5585ba5f9 p2p: skip netgroup diversity of new connections for tor/i2p/cjdns networks (stratospher)
Pull request description:
Follow up for #27264.
In order to make sure that our persistent outbound slots belong to different netgroups, distinct net groups of our peers are added to `setConnected`. We’d only open a persistent outbound connection to peers which have a different netgroup compared to those netgroups present in `setConnected`.
Current `GetGroup()` logic assumes route-based diversification behaviour for tor/i2p/cjdns addresses (addresses are public key based and not route-based). Distinct netgroups possible (according to the current `GetGroup()` logic) for:
1. tor => 030f, 031f, .. 03ff (16 possibilities)
2. i2p => 040f, 041f, .. 04ff (16 possibilities)
3. cjdns => 05fc0f, 05fc1f, ... 05fcff (16 possibilities)
`setConnected` is used in `ThreadOpenConnections()` before making [outbound](84f4ac39fd/src/net.cpp (L1846)) and [anchor](84f4ac39fd/src/net.cpp (L1805)) connections to new peers so that they belong to distinct netgroups.
**behaviour on master**
- if we run a node only on tor/i2p/cjdns
- we wouldn't be able to open more than 16 outbound connections(manual, block-relay-only anchor, outbound full relay, block-relay-only connections) because we run out of possible netgroups.
- see https://github.com/bitcoin/bitcoin/pull/27264#issuecomment-1481322628
- tested by changing `MAX_OUTBOUND_FULL_RELAY_CONNECTIONS` to 17 with `onlynet=onion` and observed how node wouldn't make more than 16 outbound connections.
**behaviour on PR**
- netgroup diversity checks are skipped for tor/i2p/cjdns addresses.
- we don't insert tor/i2p/cjdns address in `setConnected` and `GetGroup` doesn't get called on tor/i2p/cjdns(see #27369)

f73782a903 doc: fix/improve warning helps in {create,load,unload,restore}wallet (Jon Atack)
Pull request description:
Based on discussion and concept ACKed in #27138, add a `warnings` field to RPCs createwallet, loadwallet, unloadwallet, and restorewallet as a JSON array of strings to replace the `warning` string field in these 4 RPCs. The idea is to more gracefully handle multiple warning messages and for consistency with other wallet RPCs. Then, deprecate the latter fields, which represent all the remaining RPC `warning` fields.
The first commit f73782a903 implements https://github.com/bitcoin/bitcoin/pull/27138#issuecomment-1474789198 as an alternative to #27138. One of those two could potentially be backported to our currently supported releases.

This is cleanup that doesn't change external behavior.
- Removes awkward `StringMap` intermediate representation
- Simplifies CWallet code, deals with used address and received request
serialization in walletdb.cpp
- Adds test coverage and documentation
- Reduces memory usage
This PR doesn't change externally observable behavior. Internally, only change
in behavior is that EraseDestData deletes directly from database because the
`StringMap` is gone. This is more direct and efficient because it uses a single
btree 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

Instead of storing and passing around fixed strings for the purpose of
an address, use an enum.
This also rationalizes the CAddressBookData struct, documenting all fields and
making them public, and simplifying the representation to avoid bugs like
https://github.com/bitcoin/bitcoin/pull/26761#discussion_r1134615114 and make
it not possible to invalid address data like change addresses with labels.

dc1cc1c359 gui: bugfix, getAvailableBalance skips selected coins (furszy)
Pull request description:
Fixes https://github.com/bitcoin-core/gui/issues/688 and https://github.com/bitcoin/bitcoin/issues/26687.
First Issue Description (https://github.com/bitcoin-core/gui/issues/688):
The previous behavior for `getAvailableBalance`, when the coin control had selected coins, was to return the sum of them. Instead, we are currently returning the wallet's available total balance minus the selected coins total amount.
Reason:
Missed to update the `GetAvailableBalance` function to include the coin control selected coins on #25685.
Context:
Since #25685 we skip the selected coins inside `AvailableCoins`, the reason is that there is no need to waste resources walking through the entire wallet's txes map just to get coins that could have gotten by just doing a simple `mapWallet.find`).
Places Where This Generates Issues (only when the user manually select coins via coin control):
1) The GUI balance check prior the transaction creation process.
2) The GUI "useAvailableBalance" functionality.
Note 1:
As the GUI uses a balance cache since https://github.com/bitcoin-core/gui/pull/598, this issue does not affect the regular spending process. Only arises when the user manually select coins.
Note 2:
Added test coverage for the `useAvailableBalance` functionality.
----------------------------------
Second Issue Description (https://github.com/bitcoin/bitcoin/issues/26687):
As we are using a cached balance on `WalletModel::getAvailableBalance`,
the function needs to include the watch-only available balance for wallets
with private keys disabled.

3153e7d779 [fuzz] Add HeadersSyncState target (dergoegge)
53552affca [headerssync] Make m_commit_offset protected (dergoegge)
Pull request description:
This adds a fuzz target for the `HeadersSyncState` class.
I am unsure how well this is able to cover the logic since it is just processing unserialized CBlockHeaders straight from the fuzz input (headers are sometimes made continuous). However, it does manage to get to the redownload phase so i thought it is better then not having fuzzing at all.
It would also be nice to fuzz the p2p logic that is using `HeadersSyncState` (e.g. `TryLowWorkHeadersSync`, `IsContinuationOfLowWorkHeadersSync`) but that likely requires some more work (refactoring👻).

and add the walletutil.h include header for WALLET_FLAG_AVOID_REUSE that was
already missing before this change.
WALLET_FLAG_CAVEATS is only used in one RPC, so no need to encumber wallet.h and
wallet.cpp with it, along with all of the files that include wallet.h during
their compilation. Also apply clang-format per:
git diff -U0 HEAD~1.. | ./contrib/devtools/clang-format-diff.py -p1 -i -v
This new "warnings" field is a JSON array of strings intended to replace the
"warning" string field in these four RPCs, to better handle returning multiple
warning messages and for consistency with other wallet RPCs.
When doing the feerate check for bumped transactions that replace the
outputs, we need to consider that the size of the new outputs may be
different from the old outputs and calculate the minimum feerate accordingly.
Uses a min-effective-value heap, so we can remove the least valuable input/s
while the selected weight exceeds the maximum allowed weight.
Co-authored-by: Murch <murch@murch.one>
The simplest scenario where this is useful is on the 'check_max_weight' unit test
already:
We create 1515 UTXOs with 0.033 BTC each, and 1 UTXO with 50 BTC. Then perform
Coin Selection.
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 reasons stated below).
As knapsack returns a result that exceeds the max allowed transaction size, we
fallback to SRD, which 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.

This makes it easier to handle descriptor strings manually. E.g. an RPC call that takes an array of descriptors can now use '["desc": ".../0h/..."]'.
Both markers can still be parsed. The default for new descriptors is changed to h. In normalized form h is also used. For private keys the chosen marker is preserved in a round trip.
The hdkeypath field in getaddressinfo is also impacted by this change.
The following cases were covered:
Case 1: No coin control selected coins.
- 'useAvailableBalance' should fill the amount edit box with the total available balance.
Case 2: With coin control selected coins.
- 'useAvailableBalance' should fill the amount edit box with the sum of the selected coins values.
The previous behavior for getAvailableBalance when coin control
has selected coins was to return the sum of them. Instead, we
are currently returning the wallet's available total balance minus
the selected coins total amount.
This turns into a GUI-only issue for the "use available balance"
button when the user manually select coins in the send screen.
Reason:
We missed to update the GetAvailableBalance function to include
the coin control selected coins on #25685.
Context:
Since #25685 we skip the selected coins inside `AvailableCoins`,
the reason is that there is no need to traverse the wallet's
txes map just to get coins that can directly be fetched by
their id.

18fb36367a refactor: Extract util/fs_helpers from util/system (Ben Woosley)
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". This commit was originally authored by empact and is taken from its parent PR #25152.
#### Context
There is an ongoing effort to decouple the `ArgsManager` used for command line parsing user-provided arguments from the libbitcoinkernel library (https://github.com/bitcoin/bitcoin/pull/25290, https://github.com/bitcoin/bitcoin/pull/25487, https://github.com/bitcoin/bitcoin/pull/25527, https://github.com/bitcoin/bitcoin/pull/25862, https://github.com/bitcoin/bitcoin/pull/26177, and https://github.com/bitcoin/bitcoin/pull/27125). The `ArgsManager` is defined in `system.h`. A similar pull request extracting functionality from `system.h` has been merged in https://github.com/bitcoin/bitcoin/pull/27238.
#### Changes
Next to providing better code organization, this PR removes some reliance of the tree of libbitcoinkernel header includes on `system.h` (and thus the `ArgsManager` definition) by moving filesystem related functions out of the `system.*` files.
There is already a pair of `fs.h` / `fs.cpp` in the top-level `src/` directory. They were not combined with the files introduced here, to keep the patch cleaner and more importantly because they are often included without the utility functions. The new files are therefore named `fs_helpers` and the existing `fs` files are moved into the util directory.
Further commits splitting more functionality out of `system.h` are still in #25152 and will be submitted in separate PRs once this PR has been processed.

Taking cs_main is no longer necessary since we moved
`m_recently_announced_invs` to `Peer` and `mapRelay` is actually only
accessed from the message processing thread.
Rewrite the same algo instead of reusing BlockAssembler because we have
a few extra requirements that would make the changes invasive and
difficult to review:
- Only operate on the relevant transactions rather than full mempool
- Remove transactions that will be replaced so they can't bump their ancestors
- Don't hold mempool lock outside of the constructor
- Skip things like max block weight and IsFinalTx
- Additionally calculate fees to bump remaining ancestor packages to target feerate

faf8dc496e fuzz: Remove legacy int parse fuzz tests (MarcoFalke)
Pull request description:
The fuzz tests checked that the result of the new function was equal to the legacy function. (Side note: The checks were incomplete, as evident by the follow-up fix in commit b5c9bb5cb9).
Given that they haven't found any issues in years (beside missing the above issue, that they couldn't catch), it seems time to remove them.
They may come in handy in the rare case that someone would want to modify `LocaleIndependentAtoi()` or `Parse*Int*()`, however that seems unlikely. Also, appropriate checks can be added then.

9a1d73fdff Fix segfault when shutdown during wallet open (John Moffett)
Pull request description:
Fixes#689
## Summary
If you open a wallet and send a shutdown signal during that process, you'll get a segfault when the wallet finishes opening. That's because the `WalletController` object gets deleted manually in bitcoin.cpp during shutdown, but copies of the pointer (and pointers to child objects) are dangling in various places and are accessed in queued events after the deletion.
## Details
The issue in #689 is caused by the following sequence of events:
1. Wallet open modal dialog is shown and worker thread does the actual work.
2. Every 200ms, the main event loop checks to see if a shutdown has been requested, but only if a modal is not being shown.
3. Request a shutdown while the modal window is shown.
4. The wallet open process completes, the modal window is dismissed, and various `finish` signals are sent.
5. During handling of one of the `finish` signals, `qApp->processEvents()` is [called](e9262ea32a/src/qt/sendcoinsdialog.cpp (L603)), which causes the main event loop to detect the shutdown (now that the modal window has been dismissed). The `WalletController` and all the `WalletModel`s are [deleted](65de8eeeca/src/qt/bitcoin.cpp (L394-L401)).
6. Control returns to the `finish` method, which eventually tries to send a [signal](e9262ea32a/src/qt/sendcoinsdialog.cpp (L167)) from a wallet model, but it's been deleted already (and the signal is sent from a now-[dangling](d8bdee0fc8/src/qt/walletview.cpp (L65)) pointer).
The simplest fix for that is to change the `qApp->processEvents()` into a `QueuedConnection` call. (The `qApp->processEvents() was a [workaround](https://github.com/bitcoin/bitcoin/pull/593#issuecomment-3050699) to get the GUI to scroll to the last item in a list that just got added, and this is just a safer way of doing that).
However, once that segfault is fixed, another segfault occurs due to some queued wallet events happening after the wallet controller object is deleted here:
65de8eeeca/src/qt/bitcoin.cpp (L394-L401)
Since `m_wallet_controller` is a copy of that pointer in `bitcoingui.cpp`, it's now dangling and `if(null)` checks won't work correctly. For instance, this line:
65de8eeeca/src/qt/bitcoingui.cpp (L413)
sets up a `QueuedConnection` to `setCurrentWallet`, but by the time control reaches that method (one event cycle after shutdown deleted `m_wallet_controller` in `bitcoin.cpp`), the underlying objects have been destroyed (but the pointers are still dangling).
Ideally, we'd use a `QPointer` or `std::shared_ptr / std::weak_ptr`s for these, but the changes would be more involved.
This is a minimal fix for the issues. Just set `m_wallet_controller` to `nullptr` in `bitcoingui.cpp`, check its value in a couple places, and avoid a use of `qApp->processEvents`.

Using swap() was rather wasteful because it had to copy the whole direct
memory data twice. Also, due to the swap() in move assignment the moved-from
object might hold on to unused memory for longer than necessary.
Move operations already are `noexcept`, so add the keyword to the methods.
This makes the `PrevectorFillVectorIndirect...` benchmarks about twice
as fast on my machine, because otherwise `std::vector` has to use a copy
when the vector resizes.

The current `FormatISO8601DateTime` function will
return an empty string if it encounters an error
when converting the `int64_t` seconds since epoch
to a formatted date time. In the unlikely case that happens,
`strStamped.pop_back()` would be undefined behavior.
In my benchmarks, using this pool allocator for CCoinsMap gives about
20% faster `-reindex-chainstate` with -dbcache=5000 with practically the
same memory usage. The change in max RSS changed was 0.3%.
The `validation_flush_tests` tests need to be updated because
memory allocation is now done in large pools instead of one node at a
time, so the limits need to be updated accordingly.
This frees up all associated memory with the map, not only the nodes.
This is necessary in preparation for using the PoolAllocator for
CCoinsMap, which does not actually free any memory on clear().
A memory resource similar to std::pmr::unsynchronized_pool_resource, but
optimized for node-based containers.

As per https://github.com/bitcoin/bitcoin/pull/26506#pullrequestreview-1211984059,
this function is no longer necessary and we can use UniValue::read() directly.
To avoid code duplication, we keep the function to throw on invalid input data
but rename it to Parse() and remove it from the header.
Preparation to deprecate ParseNonRFCJSONValue() but keep test coverage
on the underlying UniValue::read() unaffected. The test coverage on
AmountFromValue is no longer included, since that is already tested
in the rpc_parse_monetary_values test case.
Fuzzing coverage on ParseNonRFCJSONValue() was duplicated between string.cpp
and parse_univalue.cpp, only the one in parse_univalue.cpp is kept.

Pull request description:
Fixes#23144.
We currently return a general "Insufficient funds" from Coin
Selection when we actually skipped unconfirmed UTXOs that
surpassed the mempool ancestors limit.
This PR make the error clearer by returning:
"Unconfirmed UTXOs are available, but spending them creates
a chain of transactions that will be rejected by the mempool"
Also, added an early return from Coin Selection if the sum of
the discarded coins decreases the available balance below the
target amount.

The fs.* files are already part of the libbitcoin_util library. With the
introduction of the fs_helpers.* it makes sense to move fs.* into the
util/ directory as well.
This is an extraction of filesystem related functions from util/system
into their own utility file.
The background of this commit is an ongoing effort to decouple the
libbitcoinkernel library from the ArgsManager defined in system.h.
Moving these functions out of system.h allows including them from a
separate source file without including the ArgsManager definitions from
system.h.

Pull request description:
Alternate to #27276.
Devs were [suprised to realize](https://twitter.com/jamesob/status/1637237917201383425) last night that we don't have definitive logging for when a given header was first received.
This logs to the main stream when new headers are received outside of IBD, as well as when headers come in over cmpctblocks. The rationale of not hiding these under log categories is that they may be useful to have widely available when debugging strange network activity, and the marginal volume is modest.

4b7aec2951 Add mempool tracepoints (virtu)
Pull request description:
This PR adds multiple mempool tracepoints.
| tracepoint | description |
| ------------- | ------------- |
| `mempool:added` | Is called when a transaction enters the mempool |
| `mempool:removed` | ... when a transaction is removed from the mempool |
| `mempool:replaced` | ... when a transaction is replaced in the mempool |
| `mempool:rejected` | ... when a transaction is rejected from entering the mempool |
The tracepoints are further documented in `docs/tracing.md`. Usage is demonstrated in the example script `contrib/tracing/mempool_monitor.py`. Interface tests are provided in `test/functional/interface_usdt_mempool.py`.
The rationale for passing the removal reason as a string instead of numerically is that the benefits of not having to maintain a redundant enum-string mapping seem to outweigh the small cost of string generation. The reject reason is passed as string as well, although in this instance the string does not have to be generated but is readily available.

Tracepoints for added, removed, replaced, and rejected transactions.
The removal reason is passed as string instead of a numeric value, since
the benefits of not having to maintain a redundant enum-string mapping
seem to outweigh the small cost of string generation. The reject reason
is passed as string as well, although here the string does not have to
be generated but is readily available.
So far, tracepoint PRs typically included two demo scripts: a naive
bpftrace script to show raw tracepoint data and a bcc script for a more
refined view. However, as some of the ongoing changes to bpftrace
introduce a certain degree of unreliability (running some of the
existing bpftrace scripts was not possible with standard kernels and
bpftrace packages on latest stable Ubuntu, Debian, and NixOS), this PR
includes only a single bcc script that fuses the functionality of former
bpftrace and bcc scripts.

3faae99c3d p2p: Diversify connections only w.r.t *persistent* outbound peers (Gleb Naumenko)
Pull request description:
Revives #19860.
In order to make sure that our persistent outbound slots belong to different netgroups, distinct net groups of our peers are added to [`setConnected`](8c4958bd4c/src/net.cpp (L1716)). We’d only open a persistent outbound connection to peers which have a different netgroup compared to those netgroups present in `setConnected`.
**behaviour on master**
we open persistent outbound connections to peers which have different netgroups compared to outbound full relay, block relay, addrfetch and feeler connection peers.
**behaviour on PR**
netgroup diversity is based on outbound full relay, block relay and manual connection peers.
**rationale**
- addrfetch and feeler connections are short lived connections and shouldn’t affect how we select outbound peers from addrman.
- manual connections are like regular connections when viewed from addrman’s netgroup diversity point of view and should affect how we select outbound peers from addrman

Previously only the segwit utxos being spent by the psbt were looked for and
added to the psbt. Now, the full transaction corresponding to each of these
utxos (legacy and segwit) is looked for in the txindex and mempool and added
to the psbt. If txindex is disabled and the transaction is not in the mempool,
then we fall back to getting just the utxo (if segwit) from the utxo set.

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". dongcarl is the original author of this patchset, these commits were taken from https://github.com/dongcarl/bitcoin/tree/2022-03-libbitcoinkernel-chainparams-args-only.
#### Context
The bitcoin kernel library currently relies on code containing user configurations through the `ArgsManager`. This is not optimal, since as a stand-alone library it should not rely on bitcoind's argument parsing logic. Instead, its interfaces should accept control and options structs that control the kernel library's desired configuration.
Similar work towards decoupling the `ArgsManager` from the kernel has been done in
https://github.com/bitcoin/bitcoin/pull/25290, https://github.com/bitcoin/bitcoin/pull/25487, https://github.com/bitcoin/bitcoin/pull/25527 and https://github.com/bitcoin/bitcoin/pull/25862.
#### Changes
By moving the `CChainParams` class definition into the kernel and giving it new factory functions `CChainParams::{RegTest,SigNet,Main,TestNet}`it can be constructed without an `ArgsManager` reference, unlike the current factory function `CreateChainParams`.
The first few commits remove uses of `ArgsManager` within `CChainParams`. Then the `CChainParams` definition is moved to a new file in the `kernel/` subdirectory.

The verbose mempool json response can get very large. This adds an option to return the non-verbose response of just the txids. It is identical to the rpc response so the diff here is minimal.

The chainstatemanager m_options.chainparams member variable gets its
value from the global chainparams in init.cpp. This allows
validation.cpp to only include the the kernel chainparams file.
Moves chainparams code not using the ArgsManager to the kernel.
Subsequently use the kernel chainparams header now where possible in
order to further decouple chainparams call sites from gArgs.
This normalizes the behavior of initializing Main/Test/Sig/Reg
chainparams with RegTest/SigNet chainparams. These factory functions can
also easily be used from a context without an instantiated ArgsManager,
e.g. from libbitcoin kernel code, unlike the existing CreateChainParams
method.
RegTest chain params can now be initialized by configuring a
RegTestOptions struct, or with ArgsManager. This offers an interface for
creating RegTestChainParams without a gArgs object.
SigNet chain params can now be initialized by configuring a
SigNetOptions struct, or with ArgsManager. This offers an interface for
creating SigNetChainParams without a gArgs object.
Previously, we would make connections to peer from the netgroups to which
our MANUAL outbound connections belong.
However, they should be seen as regular connections from Addrman when it comes to netgroup diversity check, since the same rationale can be applied.
Note, this has nothing to do with how we connect to MANUAL connections:
we connect to them unconditionally.

This is a minimal extraction of a single function, but also the only use
of std::exception in util/system.
The background of this commit is an ongoing effort to decouple the
libbitcoinkernel library from the ArgsManager defined in system.h.
Moving the function out of system.h allows including it from a separate

763079a3f1 Squashed 'src/secp256k1/' changes from 21ffe4b22a9..bdf39000b9c (Pieter Wuille)
Pull request description:
This updates the libsecp256k1 subtree to [v0.3.0](https://github.com/bitcoin-core/secp256k1/releases/tag/v0.3.0). I don't believe there are code changes that are particularly important to Bitcoin Core, apart from the added CMake build system support.

fa3e9b420f refactor: Consistently use args over gArgs in init.cpp (MarcoFalke)
fa891120c8 refactor: Consistently use context args over gArgs in node/interfaces (MarcoFalke)
Pull request description:
Currently `node/interfaces.cpp` uses a mix of `gArgs` vs `m_context->args`. This is fine, because outside of tests those should be identical. However, it makes the code inconsistent and harder to use in tests.
Fix that by using `args` from the context consistently. Do the same in `init.cpp`, where `gArgs` and `args` are inconsistently used in the same scope or even line.

8fcbdadfad util: fix argsman dupe key error (willcl-ark)
Pull request description:
fixes#22638
Make GUI "Settings file could not be read. Do you want to reset settings to default values?" dialog actually clear all settings instead of partially keeping them when `settings.json` contains duplicate keys. This change has no effect on `bitcoind` because it treats a corrupt `settings.json` file as a hard error and doesn't attempt to modify it.
If we find a duplicate key and error, clear `values` before returning so that `WriteSettings()` will write an empty file, therefore clearing it.
This aligns with GUI behaviour added in 1ee6d0b.
The test added only checks that `values` is empty after a duplicate key is detected. This paves the way for the `abort` option in the GUI to properly clear `settings.json`, if the user selects the option, but the test does not currently check this entire mechanism (e.g. the file contents).

If `maxconnections=0`, it means our possible connections are
going to be manual (e.g via `addnode`). For this reason, we
can skip DNS seeds and set `listen` false.
We currently return "Insufficient funds" which doesn't really
describe what went wrong; the tx creation failed because of
a long-mempool-chain, not because of a lack of funds.
Also, return early from Coin Selection if the sum of the
discarded coins decreases the available balance below the
target amount.
5c938e74cf Use string interpolation for default value of -listen (ekzyis)
Pull request description:
This is a refactoring change. So I have read the following and will try to answer why this change should be accepted
> * Refactoring changes are only accepted if they are required for a feature or
bug fix or **_otherwise improve developer experience significantly_**. For example,
most "code style" refactoring changes require a thorough explanation why they
are useful, what downsides they have and why they *significantly* improve
developer experience or avoid serious programming bugs. Note that code style
is often a subjective matter. Unless they are explicitly mentioned to be
preferred in the [developer notes](/doc/developer-notes.md), stylistic code
changes are usually rejected.
I have noticed in https://github.com/bitcoin/bitcoin/pull/26899#discussion_r1086731856 that the helper message for `-listen` does not use string interpolation.
That confused me and I wasn't sure what the reasons for that are. So it could be argued this confusion (by possibly many people in the past and in the future) may already be enough to accept this change.
However, not accepting this means that if `DEFAULT_LISTEN` is ever changed, this helper message will still use the old value (however unlikely that may be).
Therefore, this PR makes the helper message consistent with how other helper messages are implemented (using string interpolation) which leads to less confusion and prevents possibly wrong documentation in the future.

fe329dc936 test: Add test for getblockfrompeer on pruned nodes (Fabian Jahr)
cd761e6b2c rpc: Add note on guarantees to getblockfrompeer (Fabian Jahr)
Pull request description:
These are additions to `getblockfrompeer` that I already [suggested on the original PR](https://github.com/bitcoin/bitcoin/pull/20295#pullrequestreview-817157738).
The two commits do the following:
1. Add a test for `getblockfrompeer` usage on pruned nodes. This is important because many use-cases for `getblockfrompeer` are in a context of a pruned node.
2. Add some information on how long the users of pruned nodes can expect the block to be available after they have used the RPC. I think the behavior is not very intuitive for users and I would not be surprised if users expect the block to be available indefinitely.

The previous code visualized the `CSubNet` object as string, then parsed that string back to `CSubNet`. This is sub-optimal given that the original `CSubNet` object can be used directly instead.
This avoids calling `LookupSubNet()` from the GUI.

Pull request description:
There may be a theoretical deadlock for the duration of the offset when the system clock is adjusted into a past time while executing `SeedStrengthen`.
Fix this by using steady clock.
Do the same in `FindBestImplementation`, which shouldn't be affected, because it discards outlier measurements. However, doing the same there for consistency seems fine.
Do the same in `FlushStateToDisk`, which should make the flushes more steady, if the system clock is adjusted by a large offset.

This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11) (parent PR: https://github.com/bitcoin/bitcoin/pull/15606)

---
When a user activates a snapshot, the serialized UTXO set data is used to create an "assumed-valid" chainstate, which becomes active in an attempt to get the node to network tip as quickly as possible. Simultaneously in the background, the already-existing chainstate continues "conventional" IBD to both accumulate full block data and serve as a belt-and-suspenders to validate the assumed-valid chainstate.
Once the background chainstate's tip reaches the base block of the snapshot used, we set `m_stop_use` on that chainstate and immediately take the hash of its UTXO set; we verify that this matches the assumeutxo value in the source code. Note that while we ultimately want to remove this background chainstate, we don't do so until the following initialization process, when we again check the UTXO set hash of the background chainstate, and if it continues to match, we remove the (now unnecessary) background chainstate, and move the (previously) assumed-valid chainstate into its place. We then reinitialize the chainstate in the normal way.
As noted in previous comments, we could do the filesystem operations "inline" immediately when the background validation completes, but that's basically just an optimization that saves disk space until the next restart. It didn't strike me as worth the risk of moving chainstate data around on disk during runtime of the node, though maybe my concerns are overblown.
The final result of this completion process is a fully-validated chain, where the only evidence that the user synced using assumeutxo is the existence of a `base_blockhash` file in the `chainstate` directory.

Also adjusts the previous snapshot chainstate init tests
to account for the fact that the init process is now attempting to
validate and complete background chainstates whose tip is at the
snapshot base block. We use a DisconnectTip() hack to preserve the
nature of the test.
Trigger completion when a background validation chainstate reaches the

Pull request description:
Add common InitConfig function to deduplicate bitcoind and bitcoin-qt code reading config files and creating the datadir.
Noticed the duplicate code while reviewing #27073 and want to remove it because difference in bitcoin-qt and bitcoind behavior make it hard to evaluate changes like #27073
There are a few minor changes in behavior:
- In bitcoin-qt, when there is a problem reading the configuration file, the GUI error text has changed from "Error: Cannot parse configuration file:" to "Error reading configuration file:" to be consistent with bitcoind.
- In bitcoind, when there is a problem reading the settings.json file, the error text has changed from "Failed loading settings file" to "Settings file could not be read" to be consistent with bitcoin-qt.
- In bitcoind, when there is a problem writing the settings.json file, the error text has changed from "Failed saving settings file" to "Settings file could not be written" to be consistent with bitcoin-qt.
- In bitcoin-qt, if there datadir is not accessible (e.g. no permission to read), there is an normal error dialog showing "Error: filesystem error: status: Permission denied [.../settings.json]", instead of an uncaught exception.

fa8481b05f util: Work around ParseHex gcc cross compiler bug (MarcoFalke)
Pull request description:
I fail to see how an explicit `ParseHex` template instantiation fails to also instantiate `TryParseHex`.
Nonetheless, to work around a compiler bug, change the explicit instantiation from `ParseHex` to `TryParseHex`. (`ParseHex` is inline anyway and will be instantiated by the compiler either way).

Pull request description:
The idea originates from https://github.com/bitcoin/bitcoin/pull/24845#issuecomment-1130310321.
Note:
For clarity, it's recommended to start reviewing from the end result to understand the structure of the flow.
#### GroupOutputs function rationale:
If "Avoid Partial Spends" is enabled, the function gathers outputs with the same script together inside a container. So Coin Selection can treats them as if them were just one possible input and either select them all or not select them.
#### How the Inputs Fetch + Selection process roughly works:
```
1. Fetch user’s manually selected inputs.
2. Fetch wallet available coins (walks through the entire wallet txes map) and insert them into a set of vectors (each vector store outputs from a single type).
3. Coin Selection Process:
Call `AttemptSelection` 8 times. Each of them expands the coin eligibility filter (accepting a larger subset of coins in the calculation) until it founds a solutions or completely fails if no solutions gets founds after the 8 rounds.
Each `AttemptSelection` call performs the following actions:
- For each output type supported by the wallet (P2SH, P2PK, P2WPKH, P2WSH and a combination of all of them):
Call ‘ChooseSelectionResult’ providing the respective, filtered by type, coins vector. Which:
I. Groups the outputs vector twice (one for positive only and a second one who includes the negative ones as well).
- GroupOutputs walks-through the entire inputted coins vector one time at least, + more if we are avoiding partial spends, to generate a vector of OutputGroups.
II. Then performs every coin selection algorithm using the recently created vector of OutputGroup: (1) BnB, (2) knapsack and (3) SRD.
III. Then returns the best solution out of them.
```
We perform the general operation of gathering outputs, with the same script, into a single container inside:
Each coins selection attempt (8 times —> each coin eligibility filter), for each of the outputs vector who were filtered by type (plus another one joining all the outputs as well if needed), twice (one for the positive only outputs effective value and a second one for all of them).
So, in the worst case scenario where no solution is found after the 8 Coin Selection attempts, the `GroupOutputs` function is called 80 times (8 * 5 * 2).
#### Improvements:
This proposal streamlines the process so that the output groups, filtered by coin eligibility and type, are created in a single loop outside of the Coin Selection Process.
The new process is as follows:
```
1. Fetch user’s manually selected inputs.
2. Fetch wallet available coins.
3. Group outputs by each coin eligibility filter and each different output type found.
4. Coin Selection Process:
Call AttemptSelection 8 times. Each of them expands the coin eligibility filter (accepting different output groups) until it founds a solutions or completely fails if no solutions gets founds after the 8 rounds.
Each ‘AttemptSelection’ call performs the following actions:
- For each output type supported by the wallet (P2SH, P2PK, P2WPKH, P2WSH and all of them):
A. Call ‘ChooseSelectionResult’ providing the respective, filtered by type, output group. Which:
I. Performs every coin selection algorithm using the provided vector of OutputGroup: (1) BnB, (2) knapsack and (3) SRD.
II. Then returns the best solution out of them.
```
Extra Note:
The next steps after this PR will be to:
1) Merge `AvailableCoins` and `GroupOutputs` processes.
2) Skip entire coin selection rounds if no new coins are added into the subsequent round.
3) Remove global feerates from the OutputGroup class.
4) Remove secondary "grouped" tx creation from `CreateTransactionInternal` by running Coin Selection results over the aps grouped outputs vs non-aps ones.

4163093d63 wallet: use Mutex for g_sqlite_mutex instead of GlobalMutex (Vasil Dimov)
Pull request description:
Using `Mutex` provides stronger guarantee than `GlobalMutex` wrt Clang's
thread safety analysis. Thus it is better to reduce the usage of
`GlobalMutex` in favor of `Mutex`.
Using `Mutex` for `g_sqlite_mutex` is ok because its usage is limited in
`wallet/sqlite.cpp` and it does not require propagating the negative
annotations to not relevant code.

The previous code visualized the `CSubNet` object as string, then
parsed that string back to `CSubNet`. This is sub-optimal given that
the original `CSubNet` object can be used directly instead.
This avoids calling `LookupSubNet()` from the GUI.

Optimizes coin selection by performing the "group outputs"
procedure only once, outside the "attempt selection" process.
Avoiding the repeated execution of the 'GroupOutputs' operation
that occurs on each coin eligibility filters (up to 8 of them);
then for every coin vector type plus one for all the coins together.
This also let us not perform coin selection over coin eligibility
filtered groups that don't add new elements.
(because, if the previous round failed, and the subsequent one has
the same coins, then this new round will fail again).
The 'GroupOutputs()' function performs the same
calculations for only-positive and mixed groups,
the only difference is that when we look for
only-positive groups, we discard negative utxos.
So, instead of wasting resources calling GroupOutputs()
for positive-only first, then call it again to include
the negative ones in the result, we can execute
GroupOutputs() only once, including in the response
both group types (positive-only and mixed).
The following scenarios are covered:
1) 10 UTXO with the same script:
partial spends is enabled --> outputs must not be grouped.
2) 10 UTXO with the same script:
partial spends disabled --> outputs must be grouped.
3) 20 UTXO, 10 one from scriptA + 10 from scriptB:
a) if partial spends is enabled --> outputs must not be grouped.
b) if partial spends is not enabled --> 2 output groups expected (one per script).
3) Try to add a negative output (value - fee < 0):
a) if "positive_only" is enabled --> negative output must be skipped.
b) if "positive_only" is disabled --> negative output must be added.
4) Try to add a non-eligible UTXO (due not fulfilling the min depth target for
"not mine" UTXOs) --> it must not be added to any group
5) Try to add a non-eligible UTXO (due not fulfilling the min depth target for
"mine" UTXOs) --> it must not be added to any group
6) Surpass the 'OUTPUT_GROUP_MAX_ENTRIES' size and verify that a second partial
group gets created.
Extract the logic that decides whether the new or the tried table is going to
be searched to the beginning of the function.

8847ce44e0 util: add missing include and fix function signature (Cory Fields)
Pull request description:
ping hebasto
Discovered while testing pre-compiled header support with CMake: https://github.com/theuni/bitcoin/commits/cmake-pch-poc. Compilation of that branch fails without this fix and succeeds with it.
Similar to the fix in #27144.
The problem of having a default argument in the definition was masked by the missing include. Using PCH forces that include, so we end up with the compiler error we should've been getting all along.

7727603e44 refactor: reduce unnecessary complexity in ParseNonRFCJSONValue (stickies-v)
1d02e59901 test: add cases to JSON parsing (stickies-v)
Pull request description:
Inspired by MarcoFalke's [comment](https://github.com/bitcoin/bitcoin/pull/26506#discussion_r1036149426). Main purpose of this PR is to minimize copying (potentially large) RPC named arguments when calling `.substr()` by using `std::string_view` instead of `std::string`. Furthermore, cleans up the code by removing unnecessary complexity in `ParseNonRFCJSONValue()` (done first to avoid refactoring required to concatenate `string` and `string_view`), updates some naming and adds a few test cases. Should not introduce any behaviour change.
## Questions
- ~Was there actually any merit to `ParseNonRFCJSONValue()` surrounding the value with brackets and then parsing it as an array? I don't see it, and the new approach doesn't fail any tests. Still a bit suspicious about it though.~
- Cleared up by https://github.com/bitcoin/bitcoin/pull/26506#pullrequestreview-1211984059
- If there are no objections to 7727603e44, I think we should follow up with a PR to rename `ParseNonRFCJSONValue()` to a local `Parse()` helper function (that throws if invalid), remove it from `client.h` and merge the test coverage we currently have on `ParseNonRFCJSONValue()` with the coverage we have on `UniValue::read()`.

Pull request description:
This adds a number of improvements to the miniscript fuzzers that all amount to rejecting invalid or overly big miniscripts early on:
* Base type propagation in the miniscript_stable fuzzers prevents constructing a large portion of miniscripts that would be illegal, with just a little bit of type logic in the fuzzer. The fuzzer input format is unchanged.
* Ops and script size tracking in GenNode means that too-large scripts (either due to script size limit or ops limit) will be detected on the fly during fuzz input processing, before actually constructing the scripts.

Add common InitConfig function to deduplicate bitcoind and bitcoin-qt code
reading config files and creating the datadir.
There are a few minor changes in behavior:
- In bitcoin-qt, when there is a problem reading the configuration file, the
GUI error text has changed from "Error: Cannot parse configuration file:" to
"Error reading configuration file:" to be consistent with bitcoind.
- In bitcoind, when there is a problem reading the settings.json file, the
error text has changed from "Failed loading settings file" to "Settings
file could not be read" to be consistent with bitcoin-qt.
- In bitcoind, when there is a problem writing the settings.json file, the
error text has changed from "Failed saving settings file" to "Settings file
could not be written" to be consistent with bitcoin-qt.
- In bitcoin-qt, if there datadir is not accessible (e.g. no permission to read),
there is an normal error dialog showing "Error: filesystem error: status:
Permission denied [.../settings.json]", instead of an uncaught exception
This is only used in the current PR to avoid ugly
`strprintf(Untranslated("%s:\n%s"), str, MakeUnorderedList(details)`
boilerplate in init code. But in the future the function could be extended and
more widely used to include more details in GUI error messages or display them
in a more readable way, see code comment.
Previous bilingual_str tinyformat::format accepted bilingual format strings,
but not bilingual arguments. Extend it to accept both. This is useful when
embedding one translated string inside another translated string, for example:
`strprintf(_("Error: %s"), message)` which would fail previously if `message`
was a bilingual_str.
Some InitError calls had trailing \n characters, causing double newlines in
error output. After this change InitError calls consistently output one newline
instead of two. Appearance of messages in the GUI does not seem to be affected.
Can be tested with:
src/bitcoind -regtest -datadir=noexist
src/qt/bitcoin-qt -regtest -datadir=noexist

Pull request description:
There are a few cases where we can mark a block and undo file as pruned in our block index, but not actually remove the files from disk.
1. If we call `FindFilesToPrune` or `FindFilesToPruneManual` and crash before `UnlinkPrunedFiles`.
2. If on Windows there is an open file handle to the file somewhere else when calling `fs::remove` in `UnlinkPrunedFiles` (https://en.cppreference.com/w/cpp/filesystem/remove, https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-deletefilew#remarks). This could be from another process, or if we are calling `ReadBlockFromDisk`/`ReadRawBlockFromDisk` without having a lock on `cs_main` (which has been allowed since ccd8ef65f9).
This PR mitigates this by scanning all pruned block files on startup after `LoadBlockIndexDB` and unlinking them again.

Use the same technique as is using in the FromString miniscript parser to
predict the final script size of the miniscript being generated in the
miniscript_stable and miniscript_smart fuzzers (by counting every unexplored
sub node as 1 script byte, which is possible because every leaf node always
adds at least 1 byte). This allows bailing out early if the script being
generated would exceed the maximum allowed size (before actually constructing
the miniscript, as that may happen only significantly later potentially).
Also add a self-check to make sure this predicted script size matches that
of generated scripts.
Keep track of the total number of ops the constructed script will have
during miniscript_stable and miniscript_smart fuzzers' GenNode, so it
can abort early if the 201 ops limit would be exceeded.
Also add a self-check that the final constructed node has the predicted
ops size limit, so we know the fuzzer's logic for keeping track of this
is correct.
Since we now keep track of all expected child node types (even if rudimentary)
in both miniscript_stable and miniscript_smart fuzzers, there is no need anymore
for the former shortcut NodeInfo constructors without sub types.
Keep track of which base type (B, K, V, or W) is desired in the miniscript_stable
ConsumeStableNode function. This allows aborting early if the constructed node
won't have the right type.
Note that this does not change the fuzzer format; the meaning of inputs in
ConsumeStableNode is unmodified. The only change is that often the fuzzer will
abort early.
The direct motivation is preventing recursing v: wrappers, which are the only
fragment type that does not otherwise increase the overall minimum possible script
size. In a later commit this will be exploited to prevent overly-large scripts from
being constructed.
Since #27073, the behaviour of GetDataDir changed to only return
the datadir path, but not create it. This also changed the behaviour
of GetDataDirNet and GetDataDirBase but the docs do not yet reflect
that.
c5825e14f8 doc: add explanation for fail_on_insufficient_dbcache (Ryan Ofsky)
7dff7da4f5 init: Return more fitting ChainStateLoadStatus if verification was interrupted (Martin Zumsande)
Pull request description:
This addresses two outstanding comments by ryanofsky from #25574:
* return `ChainstateLoadStatus::INTERRUPTED` instead of `ChainstateLoadStatus::SUCCESS` if verification was stopped by an interrupt. This would coincide with straightforward expectation, and it avoids a misleading [log entry](c5825e14f8/src/init.cpp (L1526)) in `init` for the block index load time (because that would include the verificiation, which didn't complete). It shouldn't affect node behavior otherwise because the shutdown signal would be caught in init anyway. In test, this would lead to an assert ([link](c5825e14f8/src/test/util/setup_common.cpp (L230))), which also makes more sense because benign interrupts are not expected there during init.
This can be tested by setting a large value for `-checkblocks`, interrupting the node during block verification and observing the log.

807de2cebd wallet: skip R-value grinding for external signers (Sjors Provoost)
72b763e452 wallet: annotate bools in descriptor SPKM FillPSBT() (Sjors Provoost)
Pull request description:
When producing a dummy signature for the purpose of estimating the transaction fee, do not assume an external signer performs R-value grinding on the signature.
In particular, this avoids a scenario where the fee rate is 1 sat / vbyte and a transaction with a 72 byte signature is not accepted into our mempool.
Suggested testing:
1. On master, launch with `-signet` and create an external signer wallet using e.g. a Trezor and HWI, see [guide](https://github.com/bitcoin/bitcoin/blob/master/doc/external-signer.md#example-usage) (with the GUI it should "just work" once you have the HWI path configured).
2. Create a few addresses and fund them from the faucet: https://signet.bc-2.jp/ (wait for confirmation)
3. Create another address, and now send the entire wallet to it, set the fee to 1 sat/byte
4. Most likely this transaction never gets broadcast and you won't see it on the [signet explorer](https://explorer.bc-2.jp)
5. With this PR, try again.
6. Check the explorer and inspect the transaction. Each input witness starts with either `30440220` (R has 32 bytes) or `30440221` (R has 33 bytes). See this explainer for [DER encoding](https://bitcoin.stackexchange.com/questions/92680/what-are-the-der-signature-and-sec-format).

56e370fbb9 util: add ArgsManager datadir helper functions (willcl-ark)
Pull request description:
Fixes#20070
Currently `ArgsManager::GetDataDir()` ensures it will always return a datadir by creating one if necessary. The function is shared between `bitcoind` `bitcoin-qt` and `bitcoin-cli` which results in the undesirable behaviour described in #20070.
This PR splits out the part of the function which creates directories and adds it as a standalone function, only called as part of `bitcoind` and `bitcoin-qt` init, but not `bitcoin-cli`.
`ReadConfigFiles`' behavior is changed to use the absolute path of the config file in error and warning messages instead of a relative path.
This was inadvertantly the form being tested [here](73966f75f6/test/functional/feature_config_args.py (L287)), whilst we were _not_ testing that a relative path was returned by the message even though we passed a relative path in as argument.

f36d1d5b89 Use void* throughout support/lockedpool.h (Jeffrey Czyz)
Pull request description:
Replace uses of char* with void* in Arena's member variables. Instead,
cast to char* where needed in the implementation.
Certain compiler environments disallow std::hash<char*> specializations
to prevent hashing the pointer's value instead of the string contents.
Thus, compilation fails when std::unordered_map is keyed by char*.
Explicitly using void* is a workaround in such environments. For
consistency, void* is used throughout all member variables similarly to
the public interface.
Changes to this code are covered by src/test/allocator_tests.cpp.

04f270b435 Add test for unspendable transactions and parameter 'maxburnamount' to sendrawtransaction. (David Gumberg)
Pull request description:
This PR adds a user configurable, zero by default parameter — `maxburnamount` — to `sendrawtransaction`. This PR makes bitcoin core reject transactions that contain unspendable outputs which exceed `maxburnamount`. closes#25899.
As a result of this PR, `sendrawtransaction` will by default block 3 kinds of transactions:
1. Those that begin with `OP_RETURN` - (datacarriers)
2. Those whose lengths exceed the script limit.
3. Those that contain invalid opcodes.
The user is able to configure a `maxburnamount` that will override this check and allow a user to send a potentially unspendable output into the mempool.
I see two legitimate use cases for this override:
1. Users that deliberately use `OP_RETURN` for datacarrier transactions that embed data into the blockchain.
2. Users that refuse to update, or are unable to update their bitcoin core client would be able to make use of new opcodes that their client doesn't know about.

Pull request description:
`VerifyDB()` can fail to complete due to insufficient dbcache at the level 3 checks. This PR improves the error handling in this case in the following ways:
- The rpc `-verifychain` now returns false if the check can't be completed due to insufficient cache
- During init, we only log a warning if the default values for `-checkblocks` and `-checklevel` are taken and the check doesn't complete. However, if the user actively specifies one of these args, we return with an InitError if we can't complete the check.
This PR also changes `-verifychain` RPC to return `false` if the verification didn't finish due to missing block data (pruning) or due to being interrupted by the node being shutdown.
Previously, this PR also included a fix for a possible assert during verification - this was done in #27009 (now merged).

4b1205ba37 Test case for passphrases with null characters (John Moffett)
00a0861181 Pass all characters to SecureString including nulls (John Moffett)
Pull request description:
`SecureString` is a `std::string` specialization with a secure allocator. However, in practice it's treated like a C- string (no explicit length and null-terminated). This can cause unexpected and potentially insecure behavior. For instance, if a user enters a passphrase with embedded null characters (which is possible through Qt and the JSON-RPC), it will ignore any characters after the first null, potentially giving the user a false sense of security.
Instead of assigning to `SecureString` via `std::string::c_str()`, assign it via a `std::string_view` of the original. This explicitly captures the size and still doesn't make any extraneous copies in memory.
Note to reviewers, the following all compile identically in recent `GCC` (x86-64 and ARM64) with `-O2` (and `-std=c++17`):
```C++
std::string orig_string;
std::cin >> orig_string;
SecureString s;
s.reserve(100);
// The following all compile identically
s = orig_string;
s = std::string_view{orig_string};
s.assign(std::string_view{orig_string});
s.assign(orig_string.data(), orig_string.size());
```
So it's largely a matter of preference. However, one thing to keep in mind is that we want to avoid making unnecessary copies of any sensitive data in memory.
Something like `SecureString s{orig_string};` is still invalid and probably unwanted in our case, since it'd get treated as a short string and optimized away from the secure allocator. I presume that's the reason for the `reserve()` calls.

Moves chainstate initialization into its own function. This is
necessary to later support a more readable way of handling
background-validation chainstate cleanup during init, since the
chainstate initialization functions may need to be repeated after
moving leveldb filesystem content around.
This commit isn't strictly necessary, but the alternative is to (ab)use
the `while` loop in init.cpp with a `continue` on the basis of a
specific ChainstateLoadingError return value from LoadChainstate. Not
only is this harder to read, but it can't be unittested.
The approach here lets us consolidate background-validation cleanup to
LoadChainstate, and therefore exercise it within tests.
This commit is most easily reviewed with
git diff --color-moved=dimmed-zebra
--color-moved-ws=ignore-space-change
and remove m_snapshot_validated. This state can now be inferred by the
number of isUsable chainstates.
m_disabled is used to signal that a chainstate should no longer be used
by validation logic; it is used as a sentinel when background validation
completes or if the snapshot chainstate is found to be invalid.
isUsable is a convenience method that incorporates m_disabled.

Since users may have thought the null characters in their
passphrases were actually evaluated prior to this change,
they may be surprised to learn that their passphrases no
longer work. Give them feedback to explain how to remedy
the issue.
`SecureString` is a `std::string` specialization with
a secure allocator. However, it's treated like a C-
string (no explicit length and null-terminated). This
can cause unexpected behavior. For instance, if a user
enters a passphrase with an embedded null character
(which is possible through Qt and the JSON-RPC), it will
ignore any characters after the null, giving the user
a false sense of security.
Instead of assigning `SecureString` via `std::string::c_str()`,
assign it via a `std::string_view` of the original. This
explicitly captures the size and doesn't make any extraneous
copies in memory.

Wallet passphrases are needed to top up the keypool of encrypted wallets

if a rescan requiring the wallet to be unlocked is taking place):
- `walletlock`

`m_relock_mutex` is also introduced so that the passphrase is not
deleted from memory when the timeout provided in
`walletpassphrase` is up and the wallet is still rescanning.

95f12de925 BIP341 txdata cannot be precomputed without spent outputs (Pieter Wuille)
Pull request description:
In `PrecomputedTransactionData::Init`, if `force` is set to `true`, `m_bip341_taproot_ready` is always set to true, suggesting that all its BIP341-relevant members (including `m_spent_amounts_single_hash`) are correct. If however no `spent` array of spent previous `CTxOut`s is provided, some of these members will be incorrect. This option was introduced in #21365.
That doesn't actually hurt, as without prevout data, it's fundamentally impossible to generate correct BIP341 signatures anyway, and f722a9bd13/src/script/sign.cpp (L71) should prevent the logic from being used anyway.
Still, don't set `m_bip341_taproot_ready` variable when we clearly don't have enough data to compute it.

14b4921a91 wallet: reuse change dest when recreating TX with avoidpartialspends (Matthew Zipkin)
Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/27051
When the wallet creates a transaction internally, it will also create an alternative that spends using destination groups and see if the fee difference is negligible. If it costs the user the same to send the grouped version, we send it (even if the user has `avoidpartialspends` set to `false` which is default). This patch ensures that the second transaction creation attempt re-uses the change destination selected by the first attempt. Otherwise, the first change address remains reserved, will not be used in the second attempt, and then will never be used by the wallet, leaving gaps in the BIP44 chain.
If the user had `avoidpartialspends` set to true, there is no second version of the created transaction and the change addresses are not affected.
I believe this behavior was introduced in https://github.com/bitcoin/bitcoin/pull/14582

7554b1fd66 rpc: fix successful broadcast count in `submitpackage` error msg (Sebastian Falbesoner)
Pull request description:
If a `submitpackage` RPC call errors due to any of the individual tx broadcasts failing, the returned error message is supposed to contain the number of successful broadcasts so far:
4395b7f084/src/rpc/mempool.cpp (L848-L849)
Right now this is wrongly always shown as zero. Fix this by adding the missing increment of the counter. While touching that area, the variable is also renamed to better reflect its purpose (s/num_submitted/num_broadcast/; the submission has already happened at that point) and named arguments for the `BroadcastTransaction` call are added.
(Note that the error should be really rare, as all txs have already been submitted succesfully to the mempool. IIUC this code-path could only hit if somehow a tx is being removed from the mempool between `ProcessNewPackage` and the `BroadcastTransaction` calls, e.g. if a new block is received which confirms any of the package's txs.)

cba749a9b7 refactor: rename local gArgs to args (stickies-v)
Pull request description:
Two follow-ups for #26695, both refactoring and no observed (*) behaviour change:
- Rename `gArgs` to `args` because it's not actually a global
- Add `BlockAssembler::Options` as a (private) member to `BlockAssembler` to avoid having to assign all the options individually, essentially duplicating them
Reduces LoC and makes the code more readable, in my opinion.
---
(*) as [pointed out by ajtowns](https://github.com/bitcoin/bitcoin/pull/26883#discussion_r1068247937), this PR changes the interface of `ApplyArgsManOptions()`, making this not a pure refactoring PR. In practice, `ApplyArgsManOptions()` is never called in such a way that this leads to observed behaviour change. Regardless, I've carved out the potential behaviour change into a separate commit and would be okay with dropping it, should it turn out to be controversial.

75ec6275e6 random: remove compat.h include (fanquake)
4dc12816ac random: use int for MAX_TRIES (fanquake)
Pull request description:
This change is related to removing the use of `compat.h` as a miscellaneous catch-all for unclear/platform specific includes. Somewhat prompted by IWYU-related discussion here: https://github.com/bitcoin/bitcoin/pull/26763/files#r1058861693.
The only reason `compat.h` is required in random.cpp for Windows (note the `#ifdef WIN32`), is for `ssize_t` and an "indirect" inclusion of `windows.h`. I say indirect, because `windows.h` isn't actually included in compat.h either, it's dragged in as a side-effect of other windows includes there, i.e `winsock2.h`.
Remove this coupling by replacing `ssize_t` with int, just including `windows.h` and removing compat.h.

Pull request description:
Code in the libbitcoin_kernel library should not be calling `ArgsManager` methods or trying to read options from the command line. Instead it should just get options values from simple structs and function arguments that are passed in externally. This PR removes `gArgs` accesses from `dbwrapper` and `txdb` modules by defining appropriate options structs, and is a followup to PR's #25290#25487#25527 which remove other `ArgsManager` calls from kernel modules.
This PR does not change behavior in any way. It is a simpler alternative to #25623 because the only thing it does is remove `gArgs` references from kernel code. It avoids other unnecessary changes like adding options to the kernel API (they can be added separately later).

2555a3950f p2p: ProcessAddrFetch(-seednode) is unnecessary if -connect is specified (Dhruv Mehta)
Pull request description:
If the user runs: `bitcoind -connect=X -seednode=Y`, I _think_ it is safe to ignore `-seednode`. A more populated `addrman` (via `getaddr` calls to peers in `-seednode`) is not useful in this configuration: `addrman` entries are used to initiate new outbound connections when slots are open, or to open feeler connections and keep `addrman` from getting stale. This is all done in a part of `ThreadOpenConnections` (below [this line](https://github.com/bitcoin/bitcoin/blob/master/src/net.cpp#L1803)) which is never executed when `-connect` is supplied. With `-connect`, `ThreadOpenConnections` will run [this loop](https://github.com/bitcoin/bitcoin/blob/master/src/net.cpp#L1785) and exit thread execution when interrupted.
Reviewers may also find it relevant that when `-connect` is used, we [soft disable](https://github.com/bitcoin/bitcoin/blob/master/src/init.cpp#L800) `-dnsseed` in init.cpp perhaps for the same reason i.e. seeding is not useful with `-connect`.
Running `ProcessAddrFetch` does not seem to have downside except developer confusion AFAICT. I was confused by this and felt it might affect other new bitcoiners too. If there is strong preference to not remove the line, I'd also be happy to just leave a comment there mentioning `ADDR_FETCH`/`-seednode` is irrelevant when used with `-connect`.
If this change is accepted, the node will still make `getaddr` calls to peers in `-connect` and expand `addrman`. However, disabling those `getaddr` calls would leak information about the node's configuration.

Pull request description:
Before this PR we had the somewhat confusing combination of methods:
`CNetAddr::ToStringIP()`
`CNetAddr::ToString()` (duplicate of the above)
`CService::ToStringIPPort()`
`CService::ToString()` (duplicate of the above, overrides a non-virtual method from `CNetAddr`)
`CService::ToStringPort()`
Avoid [overriding non-virtual methods](https://github.com/bitcoin/bitcoin/pull/25349/#issuecomment-1185226396).
"IP" stands for "Internet Protocol" and while sometimes "IP addresses" are called just "IPs", it is incorrect to call Tor or I2P addresses "IPs". Thus use "Addr" instead of "IP".
Change the above to:
`CNetAddr::ToStringAddr()`
`CService::ToStringAddrPort()`
The changes touch a lot of files, but are mostly mechanical.

Structurally, the wallet class shouldn't access the global `ArgsManager` class, its internal behavior shouldn't be coupled to a global command line args parsing object.

Extra note:
In the process of removing the args ref member, discovered and fixed files that were invalidly depending on the wallet header including `util/system.h`.

The rpc command verifychain now fails if the dbcache was not sufficient
to complete the verification at the specified level and depth.
In the same situation, the VerifyDB check during Init will now fail (and lead to
an early shutdown) if the user has explicitly specified -checkblocks or
-checklevel but the check couldn't be executed because of the limited
cache. If the user didn't change any of the two and is using the defaults, log a warning
but don't prevent the node from starting up.
This does not change behavior. It is in preparation for
special handling of the case where VerifyDB doesn't finish
for various reasons, but doesn't fail.

This implements a modification of the proposal in #22007: instead of **adding** outputs to the set of outputs in the original transaction, the outputs given by `outputs` argument **completely replace** the outputs in the original transaction.
As noted below, this makes it easier to "cancel" a transaction or to reduce the amounts in the outputs, which is not the case with the original proposal in #22007, but it seems from the discussion in this PR that the **replace** behavior is more desirable than **add** one.

Since migration reloads the wallet, the wallet will always be locked
unless the passphrase is given. migratewallet can now take the
passphrase in order to unlock the wallet for migration.
An overload of MigrateLegacyToDescriptor is added which takes the wallet
name. The original that took a wallet pointer is still available, it
just gets the name, closes the wallet, and calls the new overload.
Using a FillableSigningProvider results in decodescript being unable to
infer descriptors for scripts larger than 520 bytes. Using a
FlatSigningProvider resolves this.

Since we no longer store a ref to the global `ArgsManager`
inside the wallet, we can move the util/system.h
include to the cpp.
This dependency removal opened a can of worms, as few
other places were, invalidly, depending on the wallet's
header including it.
691eaf8873 Pass MSG_MORE flag when sending non-final network messages (Matt Whitlock)
Pull request description:
**N.B.:** This is my second attempt at introducing this optimization. #12519 (2018) was closed in deference to switching to doing gathering socket writes using `sendmsg(2)`, which I agree would have superior performance due to fewer syscalls, but that work was apparently abandoned in late 2018. Ever since, Bitcoin Core has continued writing tons of runt packets to the wire. Can we proceed with my halfway solution for now?
----
Since Nagle's algorithm is disabled, each and every call to `send(2)` can potentially generate a separate TCP segment on the wire. This is especially inefficient when sending the tiny header preceding each message payload.
Linux implements a `MSG_MORE` flag that tells the kernel not to push the passed data immediately to the connected peer but rather to collect it in the socket's internal transmit buffer where it can be combined with data from successive calls to `send(2)`. Where available, specify this flag when calling `send(2)` in `CConnman::SocketSendData(CNode &)` if the data buffer being sent is not the last one in `node.vSendMsg`.

Pull request description:
This is an alternative to #25354 (by my benchmarking, somewhat faster), subsumes #25712, and adds additional test vectors.
It separates the multiple-of-64-bytes-only "core" logic (which becomes simpler) from a layer around which performs caching/slicing to support arbitrary byte amounts. Both have their uses (in particular, the MuHash3072 code can benefit from multiple-of-64-bytes assumptions), plus the separation results in more readable code. Also, since FastRandomContext effectively had its own (more naive) caching on top of ChaCha20, that can be dropped in favor of ChaCha20's new built-in caching.
I thought about rebasing #25712 on top of this, but the changes before are fairly extensive, so redid it instead.

9d3127b11e Add settings.json prune-prev, proxy-prev, onion-prev settings (Ryan Ofsky)
Pull request description:
With #602, if proxy and pruning settings are disabled in the GUI and the GUI is restarted, proxy and prune values are not stored anywhere. So if these settings are enabled in the future, default values will be shown, not previous values.
This PR stores previous values so they will preserved across restarts. I'm not sure I like this behavior because showing default values seems simpler and safer to me. Previous values may just have been set temporarily and may have never actually worked, and it adds some code complexity to store them.
This PR is one way of resolving #596. Other solutions are possible and could be implemented as alternatives.

77192c9598 cli: include local ("unreachable") peers in -netinfo table (Matthew Zipkin)
Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/26579
The `-netinfo` dashboard did not list peers that were connected via "unroutable" networks. This included local peers including local-network peers. Personally, I run one bitcoind instance on my network that is used by other services like Wasabi Wallet and LND running on other machines.
This PR adds an "npr" (not publicly routable) column to the table of networks (ipv4, ipv6, onion, etc) so that every connection to the node is listed, and the totals are accurate as they relate to max inbound and max outbound limits.
Example connecting in regtest mode to one local and one remote peer:

`m_relock_mutex` is introduced so that the passphrase is not
deleted from memory when the timeout provided in
`walletpassphrase` is up, but the wallet is still rescanning.
Wallet passphrases are needed to top up the keypool during a
rescan. The following RPCs need the passphrase when rescanning:
- `importdescriptors`
- `rescanblockchain`
The following RPCs use the information about whether or not the
passphrase is being used to ensure that full rescans are able to
take place:
- `walletlock`
- `encryptwallet`
- `walletpassphrasechange`
3a11adc700 Zero out wallet master key upon lock (John Moffett)
Pull request description:
When an encrypted wallet is locked (for instance via the RPC `walletlock`), the documentation indicates that the key is removed from memory:
b92d609fb2/src/wallet/rpc/encrypt.cpp (L157-L158)
However, the vector (a `std::vector<unsigned char, secure_allocator<unsigned char>>`) is merely _cleared_. As it is a member variable, it also stays in scope as long as the wallet is loaded, preventing the secure allocator from deallocating. This allows the key to persist indefinitely in memory. I confirmed this behavior on my macOS machine by using an open-source third party memory inspector ("Bit Slicer"). I was able to find my wallet's master key in Bit Slicer after unlocking and re-locking my encrypted wallet. I then confirmed the key data was at the address in LLDB.
This PR manually fills the bytes with zeroes before calling `clear()` by using our `memory_cleanse` function, which is designed to prevent the compiler from optimizing it away. I confirmed that it does remove the data from memory on my machine upon locking.
Note: An alternative approach could be to call `vMasterKey.shrink_to_fit()` after the `clear()`, which would trigger the secure allocator's deallocation. However, `shrink_to_fit()` is not _guaranteed_ to actually change the vector's capacity, so I think it's unwise to rely on it.
## Edit: A little more clarity on why this is an improvement.
Since `mlock`ed memory is guaranteed not to be swapped to disk and our threat model doesn't consider a super-user monitoring the memory in realtime, why is this an improvement? Most importantly, consider hibernation. Even `mlock`ed memory may get written to disk. From the `mlock` [manpage](https://man7.org/linux/man-pages/man2/mlock.2.html):
> (But be aware that the suspend mode on laptops and some desktop computers will save a copy of the system's RAM to disk, regardless of memory locks.)
As far as I can tell, this is true of [Windows](https://web.archive.org/web/20190127110059/https://blogs.msdn.microsoft.com/oldnewthing/20140207-00/?p=1833#:~:text=%5BThere%20does%20not%20appear%20to%20be%20any%20guarantee%20that%20the%20memory%20won%27t%20be%20written%20to%20disk%20while%20locked.%20As%20you%20noted%2C%20the%20machine%20may%20be%20hibernated%2C%20or%20it%20may%20be%20running%20in%20a%20VM%20that%20gets%20snapshotted.%20%2DRaymond%5D) and macOS as well.
Therefore, a user with a strong OS password and a strong wallet passphrase could still have their keys stolen if a thief takes their (hibernated) machine and reads the permanent storage.

This is a "dumb" way of randomly generating a Miniscript node from
fuzzer input. It defines a strict binary encoding and will always generate
a node defined from the encoding without "helping" to create valid nodes.
It will cut through as soon as it encounters an invalid fragment so
hopefully the fuzzer can tend to learn the encoding and generate valid
nodes with a higher probability.
On a valid generated node a number of invariants are checked, especially
around the satisfactions and testing them against the Script
interpreter.
The node generation and testing is modular in order to later introduce
other ways to generate nodes from fuzzer inputs with minimal code.
Co-Authored-By: Pieter Wuille <pieter@wuille.net>
This is a workaround for Miniscript descriptors containing hash
challenges. For those we can't mock the signature creator without making
OP_EQUAL mockable in the interpreter, so CalculateMaximumInputSize will
always return -1 and outputs for these descriptors would appear
unsolvable while they actually are.
Try to solve a script using the Miniscript satisfier if the legacy
solver fails under P2WSH context. Only solve public key and public key
hash challenges for now.
We don't entirely replace the raw solver and especially rule out trying to
solve CHECKMULTISIG-based multisigs with the Miniscript satisfier since
some features, such as the transaction input combiner, rely on the
specific behaviour of the former.

935acdcc79 refactor: modernize the implementation of uint256.* (pasta)
Pull request description:
- Constructors of uint256 to utilize Span instead of requiring a std::vector
- converts m_data into a std::array
- Prefers using `WIDTH` instead of `sizeof(m_data)`
- make all the things constexpr
- replace C style functions with c++ equivalents
- memset -> std::fill
This may also be replaced by std::memset, but I think that std::fill is more idiomatic of modern c++ and readable.
- memcpy -> std::copy
Note: In practice, implementations of std::copy avoid multiple assignments and use bulk copy functions such as std::memmove if the value type is TriviallyCopyable and the iterator types satisfy LegacyContiguousIterator. (https://en.cppreference.com/w/cpp/algorithm/copy)
This could also likely be replaced by std::memcpy, but as said above, I believe the using std::copy is the more c++ way to do anything and is almost guaranteed to compile to the same asm
- memcmp -> std::memcmp

fe683f3524 log: Log VerifyDB Progress over multiple lines (Martin Zumsande)
61431e3a57 validation: Skip VerifyDB checks of level >=3 if dbcache is too small (Martin Zumsande)
Pull request description:
This is the first two commits from #25574, leaving out all changes to `-verifychain` error-handling :
- The Problem of [25563](https://github.com/bitcoin/bitcoin/issues/25563) is that when we skip blocks at level 3 due to an insufficient dbcache (skipping some `DisconnectBlock()` calls), we would still attempt the level 4 checks, attempting to reconnect a block that was never disconnected, leading to an assert in `ConnectBlock()`.
Fix this by not attempting level 4 checks in this case.
- Logging of verification progress is now split over multiple lines. This is more verbose, but now each update has its own timestamp, and other threads logging concurrently will no longer lead to mangled output.
This can be tested with a small `dbcache` value, for example:
`bitcoind -signet -dbcache=10`
`bitcoin-cli -signet verifychain 4 1000`

Silently emitting an error makes it a bit harder to debug. Instead,
print a helpful log message to point the developer in the right
direction.
Alternatively this could have been implemented by just removing the
recipe echo suppression (@), but the subsequent make output became too
noisy.
When generating new files as part of the Makefile the recipe is
sometimes suppressed with $(AM_V_GEN) and sometimes with `@`. We should
prefer $(AM_V_GEN), since this also prints the lines in silent mode.
This is arguably more in style with the current recipe echoing.
Before:
Generated test/data/script_tests.json.h
Now:
GEN test/data/script_tests.json.h
A side effect of this change is that the recipe for generating build.h
is now echoed on each make run. Arguably this makes its generation more
transparent.

One test case uses snprintf to convert an
int to a string. Change it to use ToString
(which uses a locale-independent version of
std::to_string). Also remove unnecessary
parts of StringContentsSerializer.
The descriptor inference logic would previously always use a dummy
signing provider and would never analyze the witness script of a P2WSH
scriptPubKey.
Note even a valid Miniscript might not always be decodable from Script
without more contextual information (for instance the key preimage for a
pk_h).

Nothing has changed that would affect Bitcoin's usage of nanobench. Here is a detailed list of the changes
* Plenty of clang-tidy updates
* documentation updates
* faster Rng::shuffle
* Enable perf counters on older kernels
* Raise default minimum epoch time to 1ms (doesn't effect bitcoin's usage)
* Add support for custom information per benchmark

576f7b8614 Fix misleading RPC console wallet message (John Moffett)
Pull request description:
## Misleading message from RPCConsole window ##
In certain circumstances, the GUI console will display the message 'Executing command without any wallet' when it is, in fact, using the currently loaded wallet. For instance:
In RPC calls, if no wallet is explicitly selected and there is exactly one wallet loaded, the [default](39363a4b94/src/wallet/rpc/util.cpp (L71-L93)) is to act on that loaded wallet.
The GUI console acts that way in reality, but sometimes erroneously reports that it's not acting on any particular wallet. The root issue is due to the logic that prevents changing the selected wallet if the RPCConsole is visible:
39363a4b94/src/qt/rpcconsole.cpp (L783-L786)
This PR removes that unnecessary logic. This does have some ramifications. Prior to this PR, if a user opened the console window without any wallets loaded, then opened two or more wallets, the RPC console would select "None" of the wallets and any wallet-specific RPCs would fail. However, the behavior was different if the user hadn't had the console window open. In that case, if they opened the RPC Console window _after_ loading at least the first wallet, it would select the first-loaded wallet. This context-dependent behavior is (IMO) undesirable, and this PR changes it to be consistent.

08209c039f Correctly limit overview transaction list (John Moffett)
Pull request description:
Fixes#703
The way the main overview page limits the number of transactions displayed (currently 5) is not an appropriate use of Qt. Our subclassed transaction sort/filter proxy model returns a maximum of `5` in `rowCount()`. However, the model itself actually may hold significantly more. While this has _worked_, it breaks the contract of `rowCount()`.
If `bitcoin-qt` is run with a DEBUG build of Qt, it'll result in an assert-crash in certain relatively common situations (see #703 for details). Instead of artificially limiting the `rowCount()` in the subclassed filter, we can hide/unhide the rows in the displaying `QListView` upon any changes in the sorted proxy filter.
I loaded a wallet with 20,000 transactions and did not notice any performance differences between master and this branch.
For reference, this is the list I'm referring to:

fa47b28dfc refactor: Remove unused CDataStream SerializeMany constructor (MarcoFalke)
Pull request description:
Seems odd to have an unused method. Moreover, the function is fragile and dangerous, because one could have a `std::vector vec_a` and type `CDataStream{vec_a, 0, 0}.size()` and `CDataStream{0, 0, vec_a}.size()`, assuming they are the same thing, when in fact they are not. (The first takes over the memory as is, the second serializes the vector).
So my suggestion would be to remove the unused method and introduce a new method when this functionality is needed. For example: `static DataStream FromMany(Args&&... args)`.

59cc66abb9 test: Remove AddrMan unit test that fails consistency checks (Martin Zumsande)
Pull request description:
Two fixups for #26847:
* Now that `AddrMan::Size()` performs internal consistency tests (it didn't before), we can't call it in the `load_addrman_corrupted` unit tests, where we deal with an artificially corrupted `AddrMan`. This would fail the test when using `-checkaddrman=1` (leading to spurious CI fails). Therefore remove the tests assertion, which is not particularly helpful anyway (in production we abort init when peers.dat is corrupted instead of querying AddrMan in its corrupted state).
(See https://github.com/bitcoin/bitcoin/pull/26847#issuecomment-1411458339)

dfc01ccd73 net: simplify the call to vProcessMsg.splice() (Vasil Dimov)
Pull request description:
At the time when
```cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg, pnode->vRecvMsg.begin(), it);
```
is called, `it` is certainly `pnode->vRecvMsg.end()` which makes the call equivalent to:
```cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg, pnode->vRecvMsg.begin(), pnode->vRecvMsg.end());
```
which is equivalent to:
```cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg);
```
Thus, use the latter. Further, maybe irrelevant, but the latter has constant complexity while the original code is `O(length of vRecvMsg)`.

d35595a78a addrman: add function to return size by network and table (Martin Zumsande)
Pull request description:
AddrMan currently doesn't track the number of its entries by network, it only knows the total number of addresses. This PR makes AddrMan keep track of these numbers, which would be helpful for multiple things:
1. Allow to specifically add fixed seeds to AddrMan of networks where we don't have any addresses yet - even if AddrMan as a whole is not empty (partly fixing #26035). This is in particular helpful if the user abruptly changes `-onlynet` settings (such that addrs that used to be reachable are no longer and vice versa), in which case they currently could get stuck and not find any outbound peers. The second commit of this PR implements this.
1. (Future work): Add logic for automatic connection management with respect to networks - such as making attempts to have at least one connection to each reachable network as suggested [here](https://github.com/bitcoin/bitcoin/issues/26035#issuecomment-1249420209). This would involve requesting an address from a particular network from AddrMan, and expanding its corresponding function `AddrMan::Select()` to do this requires internal knowledge of the current number of addresses for each network and table to avoid getting stuck in endless loops.
1. (Future work): Perhaps display the totals to users. At least I would find this helpful to debug, the existing option (`./bitcoin-cli -addrinfo`) is rather indirect by doing the aggregation itself in each call, doesn't distinguish between new and tried, and being based on `AddrMan::GetAddr()` it's also subject to a quality filter which we probably don't want in this spot.

ConnectBlock assert.
The variable skipped_l3_checks is introduced because even with an
insufficient cache for the L3 checks, the L1/L2 checks in the same

Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal
---
In certain circumstances, we may want to flush chainstate data to disk without
emptying `cacheCoins`, which affects performance. UTXO snapshot
activation is one such case, as we populate `cacheCoins` with the snapshot
contents and want to persist immediately afterwards but also enter IBD.
See also #15265, which makes the case that under normal operation a
flush-without-erase doesn't necessarily add much benefit. I open this PR
even in light of the previous discussion because (i) flush-without-erase
almost certainly provides benefit in the case of snapshot activation (especially
on spinning disk hardware) and (ii) this diff is fairly small and gives us convenient
options for more granular cache management without changing existing policy.
See also #15218.

This PR removes the `--enable-upnp-default` and `--enable-natpmp-default` options from configure.
It's odd to me that we maintain configure-time options for setting the default port-forwarding runtime state (but no other similar options), and I'm not sure what use-case it satisfies, that can't be achieved by multiple other means. I also doubt that we'll ever restart using these in release builds, or turning on any of this by default.
I think the only scenario these options would be used is when you want to compile your own binaries (we don't use them in Guix), with port-forwarding on by default, but otherwise can't or don't want to use a `.conf` file, can't or don't want to pass command line options at runtime, and also don't want to modify the source code?

pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg, pnode->vRecvMsg.begin(), it);
```
is called, `it` is certainly `pnode->vRecvMsg.end()` which makes the
call equivalent to:
```cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg, pnode->vRecvMsg.begin(), pnode->vRecvMsg.end());
```
which is equivalent to:
```cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg);
```
Thus, use the latter. Further, maybe irrelevant, but the latter has
constant complexity while the original code is `O(length of vRecvMsg)`.
b0fa5989e1 test: Check that orphaned coinbase unconf spend is still abandoned (Andrew Chow)
9addbd7890 wallet: Automatically abandon orphaned coinbases and their children (Andrew Chow)
Pull request description:
When a block is reorged out of the main chain, any descendants of the coinbase will no longer be valid. Currently they are only marked as inactive, which means that our balance calculations will still include them. In order to be excluded from the balance calculation, they need to either be abandoned or conflicted. This PR goes with the abandoned method.
Note that even when they are included in balance calculations, coin selection will not select outputs belonging to these transactions because they are not in the mempool.

39b93649c4 test: add functional test for IBD stalling logic (Martin Zumsande)
0565951f34 p2p: Make block stalling timeout adaptive (Martin Zumsande)
Pull request description:
During IBD, there is the following stalling mechanism if we can't proceed with assigning blocks from a 1024 lookahead window because all of these blocks are either already downloaded or in-flight: We'll mark the peer from which we expect the current block that would allow us to advance our tip (and thereby move the 1024 window ahead) as a possible staller. We then give this peer 2 more seconds to deliver a block (`BLOCK_STALLING_TIMEOUT`) and if it doesn't, disconnect it and assign the critical block we need to another peer.
Now the problem is that this second peer is immediately marked as a potential staller using the same mechanism and given 2 seconds as well - if our own connection is so slow that it simply takes us more than 2 seconds to download this block, that peer will also be disconnected (and so on...), leading to repeated disconnections and no progress in IBD. This has been described in #9213, and I have observed this when doing IBD on slower connections or with Tor - sometimes there would be several minutes without progress, where all we did was disconnect peers and find new ones.
The `2s` stalling timeout was introduced in #4468, when blocks weren't full and before Segwit increased the maximum possible physical size of blocks - so I think it made a lot of sense back then.
But it would be good to revisit this timeout now.
This PR makes the timout adaptive (idea by sipa):
If we disconnect a peer for stalling, we now double the timeout for the next peer (up to a maximum of 64s). If we connect a block, we half it again up to the old value of 2 seconds. That way, peers that are comparatively slower will still get disconnected, but long phases of disconnecting all peers shouldn't happen anymore.

The functionality of the old size() is covered by the new Size()
when no arguments are specified, so this does not change behavior.
Co-authored-by: Martin Zumsande <mzumsande@gmail.com>
Previously, we'd only load fixed seeds if we'd not
know any addresses at all. This change makes it possible
to change -onlynet abruptly, e.g. from -onlynet=onion to
-onlynet=i2p and still find peers.
For now, the new functionality will be used in the context of
querying fixed seeds. Other possible applications for
future changes is the use in the context of making automatic
connections to specific networks, or making more detailed info
about addrman accessible via rpc.

The way that the main overview page limits the number
of transactions displayed (currently 5) is not
an appropriate use of Qt. If it's run with a DEBUG
build of Qt, it'll result in a segfault in certain
relatively common situations. Instead of artificially
limiting the rowCount() in the subclassed proxy
filter, we hide/unhide the rows in the displaying
QListView upon any changes in the sorted proxy filter.
`TxToJSON()` and `TxToUniv()` are only to be called when we want to
decode the transaction (i.e. its details) into JSON. If `TxVerbosity` is
`SHOW_TXID`, the function should not have been (and currently is not)
called in the first place.
There is no behaviour change, current logic simply assumes anything less
than `TxVerbosity::SHOW_DETAILS_AND_PREVOUT` equals
`TxVerbosity::SHOW_DETAILS`. With this change, the assumptions and
intent become more explicit.

Pull request description:
We currently process orphans by assigning them to the peer that provided a missing parent; instead assign them to the peer that provided the orphan in the first place. This prevents a peer from being able to marginally delay another peer's transactions and also simplifies the internal API slightly. Because we're now associating orphan processing with the peer that provided the orphan originally, we no longer process orphans immediately after receiving the parent, but defer until a future call to `ProcessMessage`.

b9d5674541 init: Remove sensitive flag from rpcbind (Andrew Chow)
Pull request description:
`-rpcbind` is currently flagged as a sensitive option which means that its value will be masked when the command line args are written to the debug.log file. However this is not useful as if `rpcbind` is actually activated, the bound IP addresses will be written to the log anyways. The test `feature_config_args.py` did not catch this contradiction as the test node was not started with `rpcallowip` and so `rpcbind` was not acted upon.
This also brings `rpcbind` inline with `bind` as that is not flagged as sensitive either.

When PR#15644 made orphan processing interruptible, it also introduced a
potential 100ms delay between processing of the first and second newly
reconsiderable orphan, because it didn't check if the orphan work set
was non-empty after invoking ProcessMessage(). This adds that check, so
that ProcessMessages() will return true if there are orphans to process,
usually avoiding the 100ms delay in CConnman::ThreadMessageHandler().
If we made progress on orphans, consider that enough work for this peer
for this round of ProcessMessages. This also allows cleaning up the api
for TxOrphange:GetTxToReconsider().
Previously, when we processed a new tx we would attempt to ATMP any
orphans that considered the new tx a parent immediately, but would only
accept at most one such tx, leaving any others to be considered on a
future run of ProcessMessages(). With this patch, we don't attempt any
orphan processing immediately after receiving a tx, instead deferring
all of them until the next call to ProcessMessages().

Pull request description:
Instead of having database cursors be tied to a particular `DatabaseBatch` object and requiring its setup and teardown be separate functions in that batch, we can have cursors be separate RAII classes. This makes it easier to create and destroy cursors as well as having cursors that have slightly different behaviors.
Additionally, since reading data from a cursor is a tri-state, this PR changes the return value of the `Next` function (formerly `ReadAtCursor`) to return an Enum rather than the current system of 2 booleans. This greatly simplifies and unifies the code that deals with cursors as now there is no confusion as to what the function returns when there are no records left to be read.

1134686ef9 mempool: Don't share mempool with dbcache in blocksonly (willcl-ark)
Pull request description:
Fixes#9526
When `-blocksonly` has been set reduce default mempool size to avoid surprising resource usage via sharing un-used mempool cache space with dbcache.
In comparison to https://github.com/bitcoin/bitcoin/pull/9569 which either set `maxmempool` size to 0 when `-blocksonly` was set or else errored on startup, this change will permit `maxmempool` options being set.
This preserves the current (surprising?) behaviour of having a functional mempool in `-blocksonly` mode, to permit whitelisted peer transaction relay, whilst reducing average runtime memory usage for blocksonly nodes which either use the default settings or have otherwise configured a `maxmempool` size.
To use the previous old defaults node operators can configure their node with: `-blocksonly -maxmempool=300`.

8e3fc99427 Do not use CScript for tapleaf scripts until the tapleaf version is known (Russell O'Connor)
Pull request description:
While BIP-341 calls the contents of tapleaf a "script", only in the case that the tapleaf version is `0xc0` is this script known to be a tapscript. Otherwise the tapleaf "script" is simply an uninterpreted string of bytes.
This PR corrects the issue where the type `CScript` is used prior to the tapleaf version being known to be a tapscript. This prevents `CScript` methods from erroneously being called on non-tapscript data.
A second commit abstracts out the TapBranch hash computation in the same manner that the TapLeaf computation is already abstracted. These two abstractions ensure that the TapLeaf and TapBranch tagged hashes are always constructed properly.

5eabb61b23 addrdb: Only call Serialize() once (Martin Zumsande)
da6c7aeca3 hash: add HashedSourceWriter (Martin Zumsande)
Pull request description:
There have been various reports of corruption of `peers.dat` recently, see #26599.
As explained in [this post](https://github.com/bitcoin/bitcoin/issues/26599#issuecomment-1381082886) in more detail, the underlying issue is likely that we currently serialize `AddrMan` twice - once for the file stream, once for the hasher that helps create the checksum - and if `AddrMan` changes in between these two calls, the checksum doesn't match the data and the resulting `peers.dat` is corrupted.
This PR attempts to fix this by introducing and using `HashedSourceWriter` - a class that keeps a running hash while serializing data, similar to the existing `CHashVerifier` which does the analogous thing while unserializing data. Something like this was suggested before, see https://github.com/bitcoin/bitcoin/pull/10248#discussion_r120694343.
Fixes#26599 (not by changing the behavior in case of a crash, but by hopefully fixing the underlying cause of these corruptions).

d96d97ad30 doc: Add release note for shutdownnotify. (klementtan)
0bd73e2c45 util: Add -shutdownnotify option. (klementtan)
Pull request description:
**Description**: Similar to `-startupnotify`, this PR adds a new option to allow users to specify a command to be executed when Bitcoin Core shuts down.
**Note**: The `shutdownnotify` commands will not be executed if bitcoind shut down due to *unexpected* reasons (ie `killall -9 bitcoind`).
### Testing:
**Normal shutdown commands**
```
# start bitcoind with shutdownnotify optioin
./src/bitcoind -signet -shutdownnotify="touch foo.txt"
# shutdown bitcoind
./src/bitcoin-cli -signet stop
# check that foo.txt has been created
```
**Final RPC call**
Commands:
```
$ ./src/bitcoind -signet -nolisten -noconnect -shutdownnotify="./src/bitcoin-cli -signet getblockchaininfo > tmp.txt"
$ ./src/bitcoin-cli stop
$ cat tmp.txt
```

Pull request description:
`OMITTED_NAMED_ARG` and `OMITTED` are a confusing burden:
* It puts the burden on developers to pick the right one of the two
* They can be interchanged without introducing a compile failure or other error
* Picking the wrong one is leading to incorrect docs
* They are redundant, because the correct one can already be determined by the surrounding type
Fix all issues by making them an alias of each other; Pick the right one based on the outer type.

The previous logic would call it once for serializing into the filestream,
and then again for serializing into the hasher. If AddrMan was changed
in between these calls by another thread, the resulting peers.dat would
be corrupt with non-matching checksum and data.
Fix this by using HashedSourceWriter, which writes the data
to the underlying stream and keeps track of the hash in one go.
The warnings look like:
src/rpc/util.h:192:19: error: std::move of the const variable 'name' has no effect; remove std::move() or make the variable non-const [performance-move-const-arg,-warnings-as-errors]
: m_names{std::move(name)},
^~~~~~~~~~ ~
This enables the type check and fixes the wrong docs.

Pull request description:
It seems brittle to require `RPCTypeCheck` being called inside the code logic. Without compile-time enforcement this will lead to places where it is forgotten and thus to inconsistencies and bugs. Fix this by removing the calls to `RPCTypeCheck` and doing the check internally.
The changes should be reviewed as refactoring changes. However, if they change behavior, it will be a bugfix. For example the changes here happen to also detect/fix bugs like the one fixed in commit 3b5fb6e77a.

5ca7a7be76 rpc: Return accurate results for scanblocks (Aurèle Oulès)
Pull request description:
Implements #26322.
Adds a `filter_false_positives` mode to `scanblocks` to accurately verify results from blockfilters.
If the option is enabled, pre-results given by blockfilters will be filtered out again by checking vouts and vins of all transactions of the relevant blocks against the given descriptors.

ApplyArgsManOptions does not need to set default values for missing
arguments, these are already defined in the BlockAssembler::Options.
This commit changes the interface of ApplyArgsManOptions(). If
ApplyArgsManOptions() is called again after a option is changed,
this option will no longer be reset to the default value.
There is no observed behaviour change due to how
ApplyArgsManOptions() is currently used, and the new interface is
consistent with e.g. ValidationCacheSizes and MemPoolLimits.
Add Options as a member to BlockAssembler to avoid having to assign
all the options individually.
Additionally brings the struct more in line with how we typically
define default and ArgManager values, as e.g. with
ChainstateManager::Options and and CTxMemPool::Options

The changes themselves are not very impactful for Bitcoin Core, but include:
* It's no longer needed to specify whether contexts are for signing or verification or both (all contexts support everything), so make use of that in this PR.
* Verification operations can use the static context now, removing the need for some infrastructure in pubkey.cpp to make sure a context exists.
* Most modules are now enabled by default, so we can drop explicit enabling for them.
* CI improvements (in particular, MSVC and more recent MacOS)
* Introduction of an internal int128 type, which has no effect for GCC/Clang builds, but enables 128-bit multiplication in MSVC, giving a ~20% speedup there (but still slower than GCC/Clang).
* Release process changes (process documentation, changelog, ...).

f9ce0eadf4 For feebump, ignore abandoned descendant spends (John Moffett)
Pull request description:
Closes#26667
To be eligible for fee-bumping, a transaction must not have any of its outputs (eg - change) spent in other unconfirmed transactions in the wallet. This behavior is currently [enforced](9e229a542f/src/wallet/feebumper.cpp (L25-L28)) and [tested](9e229a542f/test/functional/wallet_bumpfee.py (L270-L286)).
However, this check shouldn't apply to spends in abandoned descendant transactions, as explained by #26667.
`CWallet::IsSpent` already carves out an exception for abandoned transactions, so we can just use that.
I've also added a new test to cover this case.

Pull request description:
Performance of block template building matters as miners likely want to be able to start mining on a block with transactions asap after a block is found. We would want to know if a mempool PR accidentally caused, for example, a 100x slowdown. An `AssembleBlock()` bench exists, but it operates on a mempool with 101 transactions, each with 0 ancestors or descendants and with the same fee. Adding a bench with a more complex mempool is useful because (1) it's more realistic (2) updating packages can potentially cause the algorithm to take a long time.

Pull request description:
This PR fixes a bug and improves the mempool accept interface to return information more predictably.
Bug: In package validation, we first try the transactions individually (see doc/policy/packages.md for more explanation) and, if they all failed for missing inputs and policy-related (i.e. fee) reasons, we'll try package validation. Otherwise, we'll just "quit early" since, for example, if a transaction had an invalid signature, adding a child will not help make it valid. Currently, when we quit early, we're not setting the `package_state` to be invalid, so the caller might think it succeeded. Also, we're returning no results - it makes more sense to return the individual transaction failure. Thanks instagibbs for catching https://github.com/bitcoin/bitcoin/pull/25038#discussion_r1013293248!
Also, make the package results interface generally more useful/predictable:
- Always return the feerate at which a transaction was considered for `CheckFeeRate` in `MempoolAcceptResult::m_effective_feerate` when it was successful. This can replace the current `PackageMempoolAcceptResult::m_package_feerate`, which only sometimes exists.
- Always provide an entry for every transaction in `PackageMempoolAcceptResult::m_tx_results` when the error is `PCKG_TX`.

In the case of `i2pacceptincoming=0` we use transient addresses
(destinations) for ourselves for each outbound connection. It may
happen that we
* create the session (and thus our address/destination too)
* fail to connect to the particular peer (e.g. if they are offline)
* dispose the unused session.
This puts unnecessary load on the I2P network because session creation
is not cheap. Is exaggerated if `onlynet=i2p` is used in which case we
will be trying to connect to I2P peers more often.
To help with this, save the created but unused sessions and pick them
later instead of creating new ones.

67e7ba8e1a rpc: Sanitize label name in various RPCs (Aurèle Oulès)
Pull request description:
The following RPCs did not sanitize the optional label name:
- importprivkey
- importaddress
- importpubkey
- importmulti
- importdescriptors
- listsinceblock
Thus is was possible to import an address with a label `*` which should not be possible.
The wildcard label is used for backwards compatibility in the `listtransactions` rpc.
I added test coverage for these RPCs.

Instead of referring to a fixed line number to a file in master (which
is obviously always quickly outdated), use a permalink tied to the
latest commit.
This makes the interface more predictable and useful. The caller
understands one or more transactions failed, and can learn what happened
with each transaction. We already have this information, so we might as
well return it.
It doesn't make sense to do this for other PackageValidationResult
values because:
- PCKG_RESULT_UNSET: this means everything succeeded, so the individual
failures are no longer accurate.
- PCKG_MEMPOOL_ERROR: something went wrong with the mempool logic;
transaction failures might not be meaningful.
- PCKG_POLICY: this means something was wrong with the package as a
whole. The caller should use the PackageValidationState to find the
error, rather than looking at individual MempoolAcceptResults.
This value creates an extremely confusing interface as its existence is
dependent upon implementation details (whether something was submitted
on its own, etc). MempoolAcceptResult::m_effective_feerate is much more
helpful, as it always exists for submitted transactions.
In certain circumstances, the GUI console will display
the message 'Executing command without any wallet' when
it is, in fact, using the default wallet.
In RPC calls, if no wallet is explicitly selected and
there is exactly one wallet loaded, the default is to
act on that loaded wallet.
The GUI console acts that way in reality, but
erroneously reports that it's not acting on any
particular wallet.
If you open a wallet and send a shutdown signal during
that process, the GUI will segfault due to some queued
wallet events happening after the wallet controller
is deleted. This is a minimal fix for those issues.
Since Nagle's algorithm is disabled, each and every call to send(2) can potentially generate a separate TCP segment on the wire. This is especially inefficient when sending the tiny header preceding each message payload.
Linux implements a MSG_MORE flag that tells the kernel not to push the passed data immediately to the connected peer but rather to collect it in the socket's internal transmit buffer where it can be combined with data from successive calls to send(2). Where available, specify this flag when calling send(2) in CConnman::SocketSendData(CNode &) if the data buffer being sent is not the last one in node.vSendMsg.
Bug: not setting package_state means package_state.IsValid() == true and
the caller does not know that this failed.
We won't be validating this transaction again, so it makes sense to return this
failure to the caller.
Rename package_state to package_state_quit_early to make it more clear
what this variable is used for and what its scope is.

21ad4e26ec test: add coverage for cross-chain wallet restore (Sebastian Falbesoner)
8c7222bda3 wallet: fix GUI crash on cross-chain legacy wallet restore (Sebastian Falbesoner)
Pull request description:
Restoring a wallet backup from another chain should result in a dedicated error message (we have _"Wallet files should not be reused across chains. Restart bitcoind with -walletcrosschain to override."_ for that). Unfortunately this is currently not the case for legacy wallet restores, as in the course of cleaning up the newly created wallet directory a `filesystem_error` exception is thrown due to the directory not being empty; the wallet database did indeed load successfully (otherwise we wouldn't know that the chain doesn't match) and hence BDB-related files and directories are already created in the wallet directory.
For bitcoind, this leads to a very confusing error message:
```
$ ./src/bitcoin-cli restorewallet test123 ~/.bitcoin/regtest/wallets/regtest_wallet/wallet.dat
error code: -1
error message: filesystem error: in remove: Directory not empty ["/home/thestack/.bitcoin/wallets/test123"]
```
Even worse, the GUI crashes in such a scenario:
```
libc++abi: terminating with uncaught exception of type std::__1::__fs::filesystem::filesystem_error: filesystem error: in remove: Directory not empty ["/home/thestack/.bitcoin/wallets/foobar"]
Abort trap (core dumped)
```
Fix this by simply deleting the whole folder via `fs::remove_all`. With this, the expected error message appears both for the `restorewallet` RPC call and in the GUI (as a message-box):
```
$ ./src/bitcoin-cli restorewallet test123 ~/.bitcoin/regtest/wallets/regtest_wallet/wallet.dat
error code: -4
error message:
Wallet loading failed. Wallet files should not be reused across chains. Restart bitcoind with -walletcrosschain to override.

3a4f8bc242 bench: add benchmark for wallet 'AvailableCoins' function. (furszy)
Pull request description:
#### Rationale
`AvailableCoins` is part of several important flows for the wallet; from RPC commands that create transactions like `fundrawtransaction`, `send`, `walletcreatefundedpsbt`, get the available balance, list the available coins with `listunspent` etc. to GUI connected processes that perform the same or similar actions: tx creation, available balance calculation, present the spendable coins in the coin control dialog.
As we are improving this process in #24699, #25005 and there are more structural changes coming on the way. This benchmark aims to ensure us that, at least, there are no regressions (obviously performance improvements are great but, at least for me, this heads into the direction of having a base metric to compare future structural changes).
#### Implementation Notes
There are 5 new benchmarks, one per wallet supported output type (LEGACY, P2SH_SEGWIT, BECH32, BECH32M), plus a multi-output-type wallet benchmark which contains outputs from all the descriptor types.
The test, by default, fills-up the wallet with 1k transactions, 2k outputs. Mainly to not consume much time if the user just want to verify that no substantial regressions were introduced. But, my expectation for those who are focused on this process is to use a much higher number locally to really note the differences across commits.

Pull request description:
Work decoupled from #25806, which cleanup and improves the Coin Selection flow further.
Adding the capability to propagate specific error messages from the Coin Selection process to the user.
Instead of always returning the general "Insufficient funds" message which is not always accurate to what happened internally.
Letting us instruct the user how to proceed under certain circumstances.
The following error messages were added:
1) If the selection result exceeds the maximum transaction weight,
we now will return:
-> "The inputs size exceeds the maximum weight. Please try sending
a smaller amount or manually consolidating your wallet's UTXOs".
2) If the user pre-selected inputs and disallowed the automatic coin
selection process (no other inputs are allowed), we now will
return:
-> "The preselected coins total amount does not cover the transaction
target. Please allow other inputs to be automatically selected or include
more coins manually".
3) The double-counted preset inputs during Coin Selection error will now
throw an "internal bug detected" message instead of crashing the node.
The essence of this work comes from several comments:

66e028f739 mempool: use util::Result for CalculateAncestorsAndCheckLimits (stickies-v)
Pull request description:
Upon reviewing the documentation for `CTxMemPool::CalculateMemPoolAncestors`, I noticed `setAncestors` was meant to be an `out` parameter but actually is an `in,out` parameter, as can be observed by adding `assert(setAncestors.empty());` as the first line in the function and running `make check`. This PR fixes this unexpected behaviour and introduces refactoring improvements to make intents and effects of the code more clear.
## Unexpected behaviour
This behaviour occurs only in the package acceptance path, currently only triggered by `testmempoolaccept` and `submitpackage` RPCs.
In `MemPoolAccept::AcceptMultipleTransactions()`, we first call `PreChecks()` and then `SubmitPackage()` with the same `Workspace ws` reference. `PreChecks` leaves `ws.m_ancestors` in a potentially non-empty state, before it is passed on to `MemPoolAccept::SubmitPackage`. `SubmitPackage` is the only place where `setAncestors` isn't guaranteed to be empty before calling `CalculateMemPoolAncestors`. The most straightforward fix is to just forcefully clear `setAncestors` at the beginning of CalculateMemPoolAncestors, which is done in the first bugfix commit.
## Improvements
### Return value instead of out-parameters
This PR updates the function signatures for `CTxMemPool::CalculateMemPoolAncestors` and `CTxMemPool::CalculateAncestorsAndCheckLimits` to use a `util::Result` return type and eliminate both the `setAncestors` `in,out`-parameter as well as the error string. It simplifies the code and makes the intent and effects more explicit.
### Observability
There are 7 instances where we currently call `CalculateMemPoolAncestors` without actually checking if the function succeeded because we assume that it can't fail, such as in [miner.cpp](69b10212ea/src/node/miner.cpp (L399)). This PR adds a new wrapper `AssumeCalculateMemPoolAncestors` function that logs such unexpected failures, or in case of debug builds even halts the program. It's not crucial to the objective, more of an observability improvement that seems sensible to add on here.

1) Cleaned duplicated code and added coverage for the 'AvailableCoins' incremental result.
2) The class `AvailableCoinsTestingSetup` inside `availablecoins_tests.cpp` is a plain copy
of `ListCoinsTestingSetup` that is inside `wallet_tests.cpp`.
So, deleted the file and moved the `BasicOutputTypesTest` test case to `wallet_tests.cpp`.
3) Added arg to include/skip locked coins from the `AvailableCoins` result. This is needed for point (1) as otherwise the wallet will spend the coins that we recently created due its closeness to the recipient amount.
Note: this last point comes from #25659 where I'm using the same functionality to clean/speedup another flow as well.

indeed load successfully (otherwise we wouldn't know that the chain doesn't
match) and hence BDB-related files and directories are created in the wallet
directory.
For bitcoind, this leads to a very confusing error message:
```
$ ./src/bitcoin-cli restorewallet test123 ~/.bitcoin/regtest/wallets/regtest_wallet/wallet.dat
error code: -1
error message: filesystem error: in remove: Directory not empty ["/home/thestack/.bitcoin/wallets/test123"]
```
Even worse, the GUI crashes in such a scenario:
```
libc++abi: terminating with uncaught exception of type std::__1::__fs::filesystem::filesystem_error: filesystem error: in remove: Directory not empty ["/home/thestack/.bitcoin/wallets/foobar"]
Abort trap (core dumped)
```
Fix this by simply deleting the whole folder via `fs::remove_all`.
The current BlockAssembler bench only tests on a mempool where all
transactions have 0 ancestors or descendants, which does not exercise
any of the package-handling logic in BlockAssembler
This makes the contents of the mempool more realistic and iterating by
ancestor feerate order more meaningful. If transactions have varying
feerates, it's also more likely that packages will need to be updated
during block template assembly.
Allows us to test BlockAssembler on transactions without signatures or
mature coinbases (which is what PopulateMempool creates). Also means
that `TestBlockValidity()` is not included in the bench timing.
This allows us to both manually manipulate options and grab values from
ArgsManager (i.e. -blockmaxweight and -blockmintxfee config options)
when constructing BlockAssembler::Options. Prior to this change, the
only way to apply the config options is by ctoring BlockAssembler with
no options, which calls DefaultOptions().
As no process should be able to trigger this error
using the regular transaction creation process, throw
a runtime_error if happens to tell users/devs to
report the bug if happens.
and not the general "Insufficient funds" when the wallet
actually have funds.
Two new error messages:
1) If the selection result exceeds the maximum transaction weight,
we now will return: "The inputs size exceeds the maximum weight".
2) If the user preselected inputs and disallowed the automatic coin
selection process (no other inputs are allowed), we now will
return: "The preselected coins total amount does not cover the
transaction target".

8c5b3646b5 Relax MIN_STANDARD_TX_NONWITNESS_SIZE to 65 non-witness bytes (Greg Sanders)
Pull request description:
Since the original fix was set to be a "reasonable" transaction to reduce allocations and the true motivation later revealed, it makes sense to relax this check to something more principled.
There are more exotic transaction patterns that could take advantage of a relaxed requirement, such as 1 input, 1 output OP_RETURN to burn a utxo to fees for CPFP purposes when change isn't practical.
Two changes could be accomplished:
1) Anything not 64 bytes could be allowed
2) Anything above 64 bytes could be allowed
In the Great Consensus Cleanup, suggestion (2)
was proposed as a consensus change, and is the simpler of the two suggestions. It would not allow an "empty" OP_RETURN but would reduce the required padding from 22 bytes to 5.
The functional test is also modified to test the actual case
we care about: 64 bytes

Pull request description:
`istream_iterator` eats whitespace charactesr which causes parsing failures for PSBTs that contain the bytes corresponding to those characters. `istreambuf_iterator` is the correct thing to use here.

6fefd49527 rpc: Require NodeStateStats object in getpeerinfo (Martin Zumsande)
Pull request description:
The objects `CNode`, `CNodeState` and `Peer` store different info about a peer - `InitializeNode()` and `FinalizeNode()` make sure that for the duration of a connection, we should always have one of each for a peer.
Therefore, there is no situation in which, as part of getpeerinfo RPC, `GetNodeStateStats()` (which requires a `CNodeState` and a `Peer` entry for a `NodeId` to succeed) could fail for a legitimate reason while the peer is connected - this can only happen if there is a race condition between peer disconnection and the `getpeerinfo` processing (see also a more detailed description of this in https://github.com/bitcoin/bitcoin/pull/26457#pullrequestreview-1181641835).
But in this case I think it's better to just not include the newly disconnected peer in the response instead of returning just parts of its data.
An earlier version of this PR also made the affected `CNodeStateStats` fields non-optional (see 5f900e27d0). Since this conflicts with #25923 and should be a separate discussion, I removed that commit from this PR.

Pull request description:
While there is no issue with the current code, `libtsan-12.2.1` on my machine does not seem to like it. This is understandable, because the nonce isn't protected by a mutex that the sanitizer can see (only by an atomic, which achieves the same).
Fix this by guarding the nonce by the existing atomic bool, which tsan seems to understand.

Copy construction of CBlockIndex objects is a footgun because of the
wide use of equality-by-pointer comparison in the code base. There are

We can't just delete the copy constructors because they are used for

Delete move constructors and declare the destructor to satisfy the
"rule of 5."
To be eligible for fee-bumping, a transaction must not have any
of its outputs (eg - change) spent in other unconfirmed transactions
in the wallet. However, this check should not apply to abandoned
transactions.
A new test case is added to cover this case.
Since commit 3340dbadd3 ("Remove
-zapwallettxes"), the `FindWalletTx` helper is only needed to read tx
hashes, so drop the other parameter and rename the method accordingly.

e75d227632 Minor fix: Don't directly delete abandoned txes (John Moffett)
Pull request description:
This fully closesbitcoin/bitcoin#12179. Currently, when a user abandons a transaction by clicking "Abandon Transaction" in the context menu, a call is made to remove it from the GUI view:
`model->getTransactionTableModel()->updateTransaction(hashQStr, CT_UPDATED, false);`
(The `false` parameter is for `bool showTransaction`)
This behavior is probably unwanted, as the transaction is not actually removed from the wallet and would show up again if the node is restarted.
However, the previous line, `model->wallet().abandonTransaction(hash);`, changes the underlying model and calls `NotifyTransactionChanged(wtx.GetHash(), CT_UPDATED);`, which queues a signal that eventually calls back to `updateTransaction`, this time with `showTransaction` set to `true`. This runs on a separate thread, so it gets called *after* the 'subsequent' `updateTransaction`. The transaction gets removed from the GUI and immediately added back.
In a nutshell, `updateTransaction` gets called twice. The first (direct) call deletes the transaction from the GUI. The second (sent via a queued signal) brings it back to the GUI. The first direct call is redundant and unwanted. Worse, if the `abandonTransaction` call fails for any reason, the transaction still gets removed from the GUI. (This is what caused bitcoin#12179. It can still be triggered if, eg., a user clicks "Abandon Transaction" the moment after a new block is found.)
There are no conditions (to my knowledge) where an abandoned transaction should be directly removed from the GUI. If the underlying model changes, the deletion should be reflected anyway by the queued signal to `updateTransaction`.
The behavior is borne out by the QT logs. To reproduce, send a transaction with RBF enabled, then bump the fee, then 'abandon transaction' on the first transaction. The logs will show something like this:
```

c1a84f108e wallet: Move fee underpayment check to after fee setting (Andrew Chow)
e5daf976d5 wallet: Rename nFeeRet in CreateTransactionInternal to current_fee (Andrew Chow)
Pull request description:
Currently the fee underpayment check occurs right after we calculate what the transaction's fee should be. However the fee paid by the transaction at that time does not always match. Notably, when doing SFFO, the fee paid at that time will almost always be less than the fee required, which then required having a bypass of the underpayment check that results in SFFO payments going through when they should not.
This PR moves the underpayment check to after fees have been finalized so that we always check whether the fee is being underpaid. This removes the exception for SFFO and unifies this behavior for both SFFO and non-SFFO txs.

Pull request description:
Make the JSON-RPC server reject requests with the same named parameter specified multiple times, instead of silently overwriting earlier parameter values with later ones.
Generally JSON keys are supposed to unique, and their order isn't supposed to be significant, so having the server silently discard duplicate keys is error-prone. Most likely if an RPC client is sending a request with duplicate keys it means something is wrong with the request and there should be an error.
After this change, named parameters are still allowed to specified multiple times on the `bitcoin-cli` command line, since `bitcoin-cli` automatically replaces earlier values with later values before sending the JSON-RPC request. This makes sense, since it's not unusual for the order of command line options to be significant or for later command line options to override earlier ones.

Do not create strings and compare them to check if one `addr:port`
equals another. Use `CService::operator==()` instead.
`strDefaultProxyGUI` was assigned the same value 3 times. Instead save
it in `const CService ui_proxy` at the beginning of the function.
Both methods do the same thing, so simplify to having just one.
`ToString()` is too generic in this case and it is unclear what it does,
given that there are similar methods:
`ToStringAddr()` (inherited from `CNetAddr`),
`ToStringPort()` and
`ToStringAddrPort()`.
Both methods do the same thing, so simplify to having just one.
Further, `CService` inherits `CNetAddr` and `CService::ToString()`
overrides `CNetAddr::ToString()` but the latter is not virtual which
may be confusing. Avoid such a confusion by not having non-virtual
methods with the same names in inheritance.
"IP" stands for "Internet Protocol".
"IP address" is sometimes shortened to just "IP" or "address".
However, Tor or I2P addresses are not "IP addresses", nor "IPs".
Thus, use "Addr" instead of "IP" for addresses that could be IP, Tor or
I2P addresses:
`CService::ToStringIPPort()` -> `CService::ToStringAddrPort()`
`CNetAddr::ToStringIP()` -> `CNetAddr::ToStringAddr()`

956c67059c refactor, doc: Improve SetupAddressRelay call in version processing (Martin Zumsande)
3c43d9db1e p2p: Don't self-advertise during VERSION processing (Gleb Naumenko)
Pull request description:
This picks up the last commit from #19843.
Previously, we would prepare to self-announce to a new peer while parsing a `version` message from that peer.
This is redundant, because we do something very similar in `MaybeSendAddr()`, which is called from `SendMessages()` after
the version handshake is finished.
There are a couple of differences:
1) `MaybeSendAddr()` self-advertises to all peers we do address relay with, not just outbound ones.
2) `GetLocalAddrForPeer()` called from `MaybeSendAddr()` makes a probabilistic decision to either advertise what they think we are or what we think we are, while `PushAddress()` on `version` deterministically only does the former if the address from the latter is unroutable.
3) During `version` processing, we haven't received a potential sendaddrv2 message from our peer yet, so self-advertisements with addresses from addrV2-only networks would always be dropped in `PushAddress()`.
Since it's confusing to have two slightly different mechanisms for self-advertising, and the one in `MaybeSendAddr()` is better, remove the one in `version`.

293849a260 univalue: Remove confusing getBool method (Ryan Ofsky)
Pull request description:
Drop `UniValue::getBool` method because it is easy to confuse with the `UniValue::get_bool` method, and could potentially cause bugs. Unlike `get_bool`, `getBool` doesn't ensure that the value is a boolean and returns false for all integer, string, array, and object values instead of throwing an exception.
The `getBool` method is also redundant because it is an alias for `isTrue`. There were only 5 `getBool()` calls in the codebase, so this commit replaces them with `isTrue()` or `get_bool()` calls as appropriate.
These changes were originally made by MarcoFalke in https://github.com/bitcoin/bitcoin/pull/26213 but were dropped to limit the scope of that PR.

We need to check that the fee is not negative even before it is
finalized. The setting of fees for SFFO may adjust the fee to be
"correct" and no longer negative, but erroneously reduce the amounts too
far. So we need to check this condition before we do those adjustments.
It doesn't make sense to be checking whether the fee paid is underpaying
before we've finished setting the fees. So do that after we have done
the reduction for SFFO and change adjustment for fee overpayment.

Pull request description:
Picking up from #21006.
After commit ccd8ef65f9 it is no longer required to hold `cs_main` when calling `ReadBlockFromDisk`. This can be verified in `master` at https://github.com/bitcoin/bitcoin/blob/master/src/node/blockstorage.cpp#L755. Same can be seen for `UndoReadFromDisk` https://github.com/bitcoin/bitcoin/blob/master/src/node/blockstorage.cpp#L485.
The first commit moves `ReadBlockFromDisk` outside the lock scope in `rest_block`, where we can see a huge performance improvement when fetching blocks with multiple threads.
My test setup, on an Intel i7 with 8 cores (16 threads):
1. Start a fully synced bitcoind, with this `bitcoin.conf`:
```
rest=1
rpcthreads=16
rpcworkqueue=64
rpcuser=user
rpcpassword=password
```
2. Run ApacheBench: 10000 requests, 16 parallel threads, fetching block nr. 750000 in binary:
```
ab -n 10000 -c 16 "http://127.0.0.1:8332/rest/block/0000000000000000000592a974b1b9f087cb77628bb4a097d5c2c11b3476a58e.bin"
```
Time per request (mean)
183 ms on master
30 ms this branch
So this can process 6.1 times as many requests, and saturates all the cores instead of keeping them partly idle waiting in the lock. With 8 threads the mean times were 90 ms on master and 19 ms on this branch, a speedup of 4.7x.
Big thanks to martinus for finding this and the original PR.
The second commit is from a suggestion on the original PR by jonatack to remove the unnecessary `LOCK(cs_main)` in the zmq notifier's `NotifyBlock`.
I also found that this approach could be applied to rpcs `getblock` (including `verbosity=3`), `getblockstats`, and `gettxoutproof` with similar very good results. The above benchmarks steps need to be modified slightly for RPC. Run the following ApacheBench command with different request data in a file named `data.json`:
```
ab -p data.json -n 10000 -c 16 -A user:password "http://127.0.0.1:8332/"
```
For `getblock`, use the following in `data.json`:
```
{"jsonrpc": "1.0", "id": "curltest", "method": "getblock", "params": ["0000000000000000000592a974b1b9f087cb77628bb4a097d5c2c11b3476a58e"]}
```
master - 184 ms mean request time
branch - 28 ms mean request time
For `getblock` with verbosity level 3, use the following in `data.json`:
```
{"jsonrpc": "1.0", "id": "curltest", "method": "getblock", "params": ["0000000000000000000592a974b1b9f087cb77628bb4a097d5c2c11b3476a58e", 3]}
```
This verbosity level fetches an undo file from disk, so it benefits from this approach as well. However, a lot of time is spent serializing to JSON so the performance gain is not as severe.
master - 818 ms mean request time
branch - 505 ms mean request time
For `getblockstats`, use the following in `data.json`:
```
{"jsonrpc": "1.0", "id": "curltest", "method": "getblockstats", "params": ["0000000000000000000592a974b1b9f087cb77628bb4a097d5c2c11b3476a58e", ["minfeerate","avgfeerate"]]}
```
This request used a lock on reading both a block and undo file, so the results are very good.
master - 244 ms mean request time
branch - 28 ms mean request time

This PR adds `label` parameter to `listsinceblock` to be able to fetch all incoming transactions having the specified label since a specific block.
It's possible to use it in `listtransactions`, however, it's only possible to set the number of transactions to return, not a specific block to fetch from. `getreceivedbylabel` only returns the total amount received, not the txs info. `listreceivedbylabel` doesn't list all the informations about the transactions and it's not possible to fetch since a block.

This makes the code more robust, see previous commit.
In general replacing isTrue with get_bool is not equivalent because
get_bool can throw exceptions, but in this case, exceptions won't happen
because of RPCTypeCheck() and isNull() checks in the preceding code.

82e272a109 refactor: Move src/interfaces/*.cpp files to libbitcoin_common.a (Ryan Ofsky)
Pull request description:
These belong in `libbitcoin_common.a`, not `libbitcoin_util.a`, because they aren't general-purpose utilities, they just contain some common glue code that is used by both the node and the wallet. Another reason not to include these in `libbitcoin_util.a` is to prevent them from being used by the kernel library.
Also rename ambiguous `MakeHandler` functions to `MakeCleanupHandler` and `MakeSignalHandler`. Cleanup function handler was introduced after boost signals handler, so original naming didn't make much sense.
This just contains a move-only commit, and a rename commit. There are no actual code or behavior changes.
This PR is an alternative to #26293, and solves the same issue of removing a boost dependency from the _util_ library. The advantages of this PR compared to #26293 are that it keeps the source directory structure more flat, and it avoids having to change #includes all over the codebase.

3198e4239e test: check that loading descriptor wallet with legacy entries throws error (Sebastian Falbesoner)

```
Background: In the wallet key-value-loading routine, most legacy type entries require a `LegacyScriptPubKeyMan` instance after successful deserialization. On a descriptor wallet, creating that (via method `GetOrCreateLegacyScriptPubKeyMan`) fails and then leads to a null-pointer dereference crash. E.g. for CSCRIPT: 50422b770a/src/wallet/walletdb.cpp (L589-L594)
~~This PR fixes this by simply ignoring legacy entries if the wallet flags indicate that we have a descriptor wallet. The second commits adds a regression test to the descriptor wallet's functional test (fortunately Python includes sqlite3 support in the standard library).~~
~~Probably it would be even better to throw a warning to the user if unexpected legacy entries are found in descriptor wallets, but I think as a first mitigation everything is obvisouly better than crashing. As far as I'm aware, descriptor wallets created/migrated by Bitcoin Core should never end up in a state containing legacy type entries though.~~
This PR fixes this by throwing an error if legacy entries are found in descriptor wallets on loading.

Pull request description:
This comes with #26559.
Solving few bugs inside the wallet's transaction creation
process and adding test coverage for them.
Plus, making use of the `CoinsResult::total_amount` cached value
inside the Coin Selection process to return early if we don't have
enough funds to cover the target amount.
### Bugs
1) The `CoinsResult::Erase` method removes only one
output from the available coins vector (there is a [loop break](c1061be14a/src/wallet/spend.cpp (L112))
that should have never been there) and not all the preset inputs.
Which on master is not a problem, because since [#25685](https://github.com/bitcoin/bitcoin/pull/25685)
we are no longer using the method. But, it's a bug on v24
(check [#26559](https://github.com/bitcoin/bitcoin/pull/26559)).
This method it's being fixed and not removed because I'm later using it to solve
another bug inside this PR.
2) As we update the total cached amount of the `CoinsResult` object inside
`AvailableCoins` and we don't use such function inside the coin selection
tests (we manually load up the `CoinsResult` object), there is a discrepancy
between the outputs that we add/erase and the total amount cached value.
### Improvements
* This makes use of the `CoinsResult` total amount field to early return
with an "Insufficient funds" error inside Coin Selection if the tx target
amount is greater than the sum of all the wallet available coins plus the
preset inputs amounts (we don't need to perform the entire coin selection
process if we already know that there aren't enough funds inside our wallet).
### Test Coverage
1) Adds test coverage for the duplicated preset input selection bug that we have in v24.
Where the wallet invalidly selects the preset inputs twice during the Coin Selection
process. Which ends up with a "good" Coin Selection result that does not cover the
total tx target amount. Which, alone, crashes the wallet due an insane fee.
But.. to make it worst, adding the subtract fee from output functionality
to this mix ends up with the wallet by-passing the "insane" fee assertion,
decreasing the output amount to fulfill the insane fee, and.. sadly,
broadcasting the tx to the network.
2) Adds test coverage for the `CoinsResult::Erase` method.

f39d9269eb rpc: warn that nodes ignore requests for old stale blocks (Sjors Provoost)
Pull request description:
Adds warning to RPC help that `getblockfrompeer` is of little use for stale blocks that are more than a month old.
This is an anti-fingerprinting measure. See `BlockRequestAllowed` in `net_processing`.
It's been in Bitcoin Core since 2014, introduced in #2910 and later improved to not rely on checkpoints.
Older and alternative clients might still serve these blocks, so not throwing an error.
Allowing whitelisted nodes to fetch these blocks anyway might be nice.

MarcoFalke reported the case of positional arguments silently overwriting the
named "args" parameter in bitcoin-cli
https://github.com/bitcoin/bitcoin/pull/19762#discussion_r1035761471 and this
behavior is confusing and was not intended when support for "args" parameters
was added to bitcoin-cli in #19762.
Instead of letting one "args" value overwrite the other in the client, just
pass the values to the server verbatim, and let the error be handled server
side.
Specifying same named parameter multiple times is still allowed by bitcoin-cli.
The client implementation overwrites earlier option values with later ones
before sending to server. This is tested by interface_bitcoin_cli.py
Rationale for allowing client parameters to be specified multiple times in
bitcoin-cli is that this behavior has been supported for a long time, and that
when using the command line interactively, it can be convenient to override
earlier option values with new values without having to go back and remove the
old value.
But for the RPC server, there isn't really a good use-case for earlier values
to be discarded if multiple values are specified. JSON keys are generally
supposed to be unique and if they aren't it's probably an indication of some
problem generating the RPC request.
Current behavior isn't ideal and will be changed in upcoming commits, but it's
useful to have test coverage regardless.

The CoinsResult class will now count the raw total amount and the effective
total amount internally (inside the 'CoinsResult::Add' and 'CoinsResult::Erase'
methods).
So there is no discrepancy between what we add/erase and the total values.
(which is what was happening on the coinselector_test because the 'CoinsResult'
object is manually created there, and we were not keeping the total amount
in sync with the outputs being added/removed).
Aside from the cleanup, this solves a bug in the following-up commit. Because, in these
tests, we are manually adding/erasing outputs from the CoinsResult object but never
updating the internal total amount field.
This exercises the bug inside CoinsResult::Erase that
ends up on (1) a wallet crash or (2) a created and
broadcasted tx that contains a reduced recipient's amount.
This is covered by making the wallet selects the preset
inputs twice during the coin selection process.
Making the wallet think that the selection process result covers
the entire tx target when it does not. It's actually creating
a tx that sends more coins than what inputs are covering for.
Which, combined with the SFFO option, makes the wallet
incorrectly reduce the recipient's amount by the difference
between the original target and the wrongly counted inputs.
Which means, a created and relayed tx sending less coins to
the destination than what the user inputted.
