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.

Rather than needing to create intermediate stream variables, we can use
helper functions like `tx_from_hex` instead or access the result
directly, leading both to increased readability and less code.
Also, move the burden of checking for a timeout to the client and
disable the timeout on the server. This should avoid intermittent issues
in slow tests (for example mining_getblocktemplate_longpoll.py, or
feature_dbcrash.py), or possibly when the server is running slow (for
example in valgrind). There shouldn't be any downside in tests caused
by a high rpcservertimeout.
e669833943 test: dedup package limit checks via decorator in mempool_package_limits.py (Sebastian Falbesoner)
72f25e238c test: refactor: use Satoshis for fees in mempool_package_limits.py (Sebastian Falbesoner)
Pull request description:
The subtests in the functional test mempool_package_limits.py all follow the same pattern:
1. first, check that the mempool is currently empty
2. create and submit certain single txs to the mempool, prepare list of hex transactions
3. check that `testmempoolaccept` on the package hex fails with a "package-mempool-limits" error on each tx result
4. after mining a block, check that submitting the package succeeds
Note that steps 1,3,4 are identical for each of the subtests and only step 2 varies, so this might be a nice opportunity to deduplicate code by using a newly introduced decorator which executes the necessary before and after the essential part of the subtest. This also makes it easier to add new subtests without having to copy-paste those parts once again.
In addition, the first commit switches the fee unit from BTC to Satoshis, which allows to get rid of some imports (`COIN` and `Decimal`) and a comment for the `test_desc_size_limits` subtest is fixed (s/25KvB/21KvB/).

e47ce42f67 refactor: use address_to_scriptpubkey to retrieve addresses scriptpubkey (ismaelsadeeq)
4142d19d74 refactor: move address_to_scriptpubkey to address.py (ismaelsadeeq)
Pull request description:
PR #27269 enables the function address_to_scriptpubkey() to decode all address types and return their corresponding scriptpubkeys. As a result, there is no longer any need to call getaddressinfo or validateaddress RPCs in order to retrieve an address scriptpubkey, as explained in the comments on this pull request (see https://github.com/bitcoin/bitcoin/pull/27269#pullrequestreview-1353681933 and https://github.com/bitcoin/bitcoin/pull/27269#issuecomment-1481016118).
Instead of using RPC calls, this update replaces the process of obtaining an address scriptPubkey with the address_to_scriptpubkey method, resulting in improved performance for functional tests.

This avoids having to convert from BTC to Sats and needs less imports.
Also specify the tx's target size in vsize rather than in weight, which
allows us to specify the fee-rate by a simple multiplication, rather
than having another magic number for it.
This commit updates the code by replacing the RPC call used to
decode an address and retrieve its corresponding scriptpubkey
with the address_to_scriptpubkey function. address_to_scriptpubkey
function can now decode all addresses formats, which makes
it more efficient to use.
The COINBASE_MATURITY constant in blocktools.py is imported in wallet.py.
However, importing address_to_scriptpubkey to blocktools.py will
generate a circular import error. Since the method is related to
addresses, it is best to move it to address.py, which will also
fix the circular import error.
Update imports of address_to_scriptpubkey accordingly.
8aab5157c5 test: wallet_create_tx.py fix race (furszy)
Pull request description:
Fixes#27316
Because wallets are internally synchronized through the validation interface,
and the interface dispatches events on a worker thread, it is possible for a
transaction created by the first wallet to not arrive to the second wallet
before the second wallet attempts to use one of its outputs. This is because
we do not wait for the `BroadcastTransaction` callback during the wallet's
"submit to mempool" process. To address this in the tests, we need to
manually sync the validation queue.

In the functional test rpc_psbt.py, some comments around the
`converttopsbt` RPC checks are wrong or outdated and can be
removed:
> Error could be either "TX decode failed" (segwit inputs causes
> parsing to fail) or "Inputs must not have scriptSigs and
> scriptWitnesses"
Decoding a valid TX with at least one input always succeeds with the
heuristic, i.e. this comment is not right and we can assert for the
error string "Inputs must not have scriptSigs and scriptWitnesses"
on the calls below.
> We must set iswitness=True because the serialized transaction has
> inputs and is therefore a witness transaction
This is also unneeded (and confusing, w.r.t. "is therefore a witness
transaction"?), for a TX with one input there is no need to set the
`iswitness` parameter. For sake of completeness, we still keep one
variant where iswitness is explicitly set to true.
Lastly, there is a superflous `converttopsbt` call on the raw tx which
is the same as just about ~10 lines above, so it can be removed.

Fix this by checking the return value (or exception) by wrapping the function execution into a future and calling `result()` on it.
Can be reviewed with `--ignore-all-space`.

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.

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.

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 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).

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.

b082f28101 rpc, wallet: use the same `next_index` in listdescriptors and importdescriptors (w0xlt)
Pull request description:
Currently `listdescriptors` RPC uses `next` key to represent `WalletDescriptor::next_index` while `importdescriptors` uses `next_index`. This creates two different descriptor formats.
This PR changes `listdescriptors` to use the same key as `importdescriptors`.

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.

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.

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

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).

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.

a804f3cfc0 wallet: extract and reuse RPC argument format definition for outputs (Seibart Nedor)
Pull request description:
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.

Pull request description:
The same procedure as every release (see dba1231672 [v23.0] and d8b705f1ca [v22.0]), only a little simpler now: thanks to #25650, the previous release fetch script defaults to downloading/building the necessary tags, i.e. we don't need to extend the tag list in the CI scripts and test/README.md anymore.

This makes the Miniscript descriptors solvable.
Note this introduces signing support for much more complex scripts than the wallet was previously able to solve, and the whole tooling isn't provided for a complete Miniscript integration in the wallet. Particularly, the PSBT<->Miniscript integration isn't entirely covered in this PR.

dee8549be3 test: simplify and speedup mempool_updatefromblock.py by using MiniWallet (Sebastian Falbesoner)
Pull request description:
This PR simplifies the functional test mempool_updatefromblock.py by using MiniWallet in order to avoid manual low-level tx creation (signing, outputs selection, fee calculation). Most of the tedious work is done by the method `MiniWallet.send_self_transfer_multi` (calling `create_self_transfer_multi` internally) which supports spending a given set of UTXOs and creating a certain number of outputs.
As a nice side-effect, the test's performance increases significantly (~3.5x on my system):

The arguments `start_input_txid` and `end_address` have been removed from the `transaction_graph_test` method, as they are currently unused and I don't see them being needed for future tests.

772671245d test: p2p: check that headers message with invalid proof-of-work disconnects peer (Sebastian Falbesoner)
Pull request description:
One of the earliest anti-DoS checks done after receiving and deserializing a `headers` message from a peer is verifying whether the proof-of-work is valid (called in method `PeerManagerImpl::ProcessHeadersMessage`):
f227e153e8/src/net_processing.cpp (L2752-L2762)
The called method `PeerManagerImpl::CheckHeadersPoW` calls `Misbehaving` with a score of 100, i.e. leading to an immediate disconnect of the peer:
f227e153e8/src/net_processing.cpp (L2368-L2372)
This PR adds a simple test for both the misbehaving log and the resulting disconnect. For creating a block header with invalid proof-of-work, we first create one that is accepted by the node (the difficulty field `nBits` is copied from the genesis block) and based on that the nonce is modified until we have block header hash prefix that is too high to fulfill even the minimum difficulty.

ab4efad51b test: fix immediate tx relay in wallet_groups.py (Sebastian Falbesoner)
Pull request description:
In the functional test wallet_groups.py we whitelist peers on all nodes (`-whitelist=noban@127.0.0.1`) to enable immediate tx relay for fast mempool synchronization. However, considering that this setting only applies to inbound peers and the default test topology looks like this:
```
node0 <--- node1 <---- node2 <--- ... <-- nodeN
```
txs propagate fast only from lower- to higher-numbered nodes (i.e. "left to right" in the above diagram) and take long from higher- to lower-numbered nodes ("right to left") since in the latter direction we only have outbound peers, where the trickle relay is still active. As a consequence, if a tx is submitted from any node other than node0, the mempool synchronization can take quite long.
This PR fixes this by simply adding another connection from node0 to the last node, leading to a ~2-3x speedup (5 runs measured via `time ./test/functional/wallet_groups.py` are shown):

We'll need a better integration of the hash preimages PSBT fields to
satisfy Miniscript with such challenges from the RPC.
Thanks to Greg Sanders for his examples and suggestions to improve this
test.
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.
