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.

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:
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.

89cd20cbed test: add coverage for sigop limit policy (`-bytespersigop` setting) (Sebastian Falbesoner)
Pull request description:
This PR adds missing test coverage for the `-bytespersigop` option, which determines how pre-taproot signature operations (OP_CHECKSIG{VERIFY}, OP_CHECKMULTIGSIG{VERIFY}) affect fee handling calculations. The setting was introduced in PR #7081 for mitigating the [sigop spam attack](https://bitcointalk.org/index.php?topic=1166928.0); the initial implementation rejected txs exceeding the limit, but was changed in #8365 later to account for higher sizes in the mempool (i.e. exceeding the sigop limit is possible, but has to be compensated by higher fees).
For each combination of `-bytespersigop` setting and sigops count, the test first creates a P2WSH spending transaction with a witness script that puts sigops in a non-executing branch (OP_FALSE OP_IF OP_CHECKMULTISIG ... OP_CHECKSIG ... OP_ENDIF). This tx is then bumped up to reach exactly the _sig-op limit equivalent vsize_ by padding its datacarrier output. Based on that, increasing the tx's vsize should still reflect a vsize increase in the mempool, while a decrease of the tx's vsize should lead to the mempool treating the tx's vsize to be the _sig-op limit equivalent vsize_, since the limit was exceeded.
I assume that this parameter is almost never set explicitly by users (also it is not relevant for taproot spends), but it doesn't hurt to have a test for it. See also https://bitcoin.stackexchange.com/a/87958 for another explanation.

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.

77557dda4a prune: scan and unlink already pruned block files on startup (Andrew Toth)
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.

7013da07fb Add release note for PR#25943 (David Gumberg)
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.
Fixes#27067.

4d84eaec82 Raise PRNG seed log to INFO. (roconnor-blockstream)
Pull request description:
Some build infrastructure, such as Nix, will delete failed builds by default, keeping only the log (stdout/stderr) of the failed build.
For flaky tests, it would be very helpful to have the PRNG seed in the default log in order to redo the failed test.
By simply raising the PRNG seed logging to INFO, we can, by default, record the seed in the log of every build.

6bdbc5ff59 rpc: Allow users to specify wallet name for migratewallet (Andrew Chow)
dbfa345403 wallet: Allow MigrateLegacyToDescriptor to take a wallet name (Andrew Chow)
Pull request description:
`migratewallet` currently operates on wallets that are already loaded, however this is not necessarily required, and in the future, not possible once the legacy wallet is removed. So we need to also be able to give the wallet name to migrate.
Additionally, the passphrase is required when migrating a wallet. Since a wallet may not be loaded when we migrate, and as we currently unload wallets when migrating, we need the passphrase to be given to `migratewallet` in order to migrate encrypted wallets.

6a5b348f2e test: test rescanning encrypted wallets (ishaanam)
493b813e17 wallet: ensure that the passphrase is not deleted from memory when being used to rescan (ishaanam)
66a86ebabb wallet: keep track of when the passphrase is needed when rescanning (ishaanam)
Pull request description:
Wallet passphrases are needed to top up the keypool of encrypted wallets
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 (meaning the following RPCs should not be able to run
if a rescan requiring the wallet to be unlocked is taking place):
- `walletlock`
- `encryptwallet`
- `walletpassphrasechange`
`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.

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

Pull request description:
`FillableSigningProvider` limits scripts to 520 bytes even though segwit allows scripts to be larger than that. We can avoid this limit by using a `FlatSigningProvider` so that such larger scripts can be decoded.

Pull request description:
Fixes#26808
When `node0` calls `disconnectnode` to disconnect `node1`, we should check in `node1` if it worked, because for `node0` the informations in `getpeerinfo` may be updated before really completing the disconnection.

14302a4802 test: fix test abort for high timeout values (and `--timeout-factor 0`) (Sebastian Falbesoner)

```
This is caused by a high timeout value that Python's HTTP(S) client library can't cope with. Fix this by clamping down the connection's set timeout value in AuthProxy. The change can easily be tested by running an arbitrary test with `--timeout-factor 0` on master (should fail), on this PR (should pass) and on this PR with the clamping value increased by 1 (should fail).
// EDIT: The behaviour was observed on OpenBSD 7.1 and Python 3.9.12.
