c84c5f6e89 p2p: set `-dnsseed` and `-listen` false if `maxconnections=0` (brunoerg)
Pull request description:
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.

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.

6d24d1ef2b test: check that sigop limit also affects ancestor/descendant size (Sebastian Falbesoner)
Pull request description:
This is a follow-up to #27171, adding a check that the sigop-limit vsize logic is also respected for {ancestor,descendant}size calculation (as suggested in https://github.com/bitcoin/bitcoin/pull/27171#pullrequestreview-1331143909). For simplicity, we use a one-parent-one-child cluster here and only check for the case that the sigop-limit equivalent size is larger than the serialized vsize.

72e8ffd7f8 p2p: Account for MANUAL conns when diversifying persistent outbound conns (Gleb Naumenko)
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

e194e3e93d test: PSBT: eliminate magic numbers for global unsigned tx key (0) (Sebastian Falbesoner)
Pull request description:
This PR adds missing test coverage for dropping non-witness UTXOs from PSBTs for segwit v1+ inputs (see commit 103c6fd279). The formerly [disabled](4600479058) method `test_utxo_conversion` is re-enabled and adapted to spend a Taproot (`bech32m`) instead of a wrapped SegWit (`p2sh-segwit`) output. Note that in contrast to the original test, we have to add the non-witness UTXO manually here using the test framework's PSBT module, since the constructing node knows that the output is segwit v1 and hence doesn't add the non-witness UTXO in the first place (see also [BIP371]( https://github.com/bitcoin/bips/blob/master/bip-0371.mediawiki#user-content-UTXO_Types)).
I strongly assume that most wallets would behave the same as Bitcoin Core here and wouldn't create PSBTs with non-witness UTXOs for Taproot inputs, but it's still good to test everything works as expected if it's still done and that the non-witness UTXO is simply dropped in that case.
The first two commits contain a small refactor (magic number elimination in PSBT module) and test speedup of ~2-3x (using whitelisting peers / immediate tx relay).

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.

Pull request description:
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. This also adds the mempool_sequence parameter for rpc consistency. Verbose defaults to true to remain backwards compatible.
It uses query parameters to be compatible with the efforts in https://github.com/bitcoin/bitcoin/issues/25752.

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.

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).
