66667d6512 test: Use same rpc timeout for authproxy and cli (MarcoFalke)
Pull request description:
It seems odd to use different timeouts (and timeout factors) depending on whether the Python RPC proxy is used, or the bitcoin rpc command line interface.
Fix it by using the same timeout.
This can be tested by introducing a timeout error and checking it happens with and without `--usecli` after the exact same time.
Example timeout error:

57f7c68821 test: add functional test for `TestShell` (matching doc example) (Sebastian Falbesoner)
53874f7934 doc: test: update TestShell example instructions/options (Sebastian Falbesoner)
Pull request description:
This PR adds a functional framework test for the `TestShell` class. The primary motivation for this is to avoid that the example instructions for the interactive Python shell in `test-shell.md` get outdated or broken without noticing, a problem we had already several times in the past (see #26520, #27906, #31415). Having a copy is still not perfect, as docs and functional test have to be kept in sync, but I don't expect this to be a problem in practice, assuming the hint in the functional test comment is hopefully noticed if changes are made.
Alternatively, the example instructions in `test-shell.md` could be removed with a hint to the functional test (I tend to prefer to keep the docs as-is though, showing the full REPL interaction).
The first commit contain two small removal fix-ups in `test-shell.md` regarding the result of the `createwallet` RPC call and the mentioning of the `noshutdown` option that was removed earlier (see #31620). Could be backported to v30.

664657ed13 bugfix: disallow label for ranged descriptors & allow external non-ranged descriptors to have label (scgbckbone)
Pull request description:
Motivation:
* ranged descriptors MUST not be able to have label (current impl allows it)
* external non-ranged descriptor MUST be able to have label (current impl disallows it, **if** `internal=false` is provided via importdescriptor user data)
Repro steps:
* create blank wallet and import descriptors
* external has `label=test` (not internal)
```
conn = bitcoind.create_wallet(wallet_name=w_name, disable_private_keys=True, blank=True,
passphrase=None, avoid_reuse=False, descriptors=True)
descriptors = [
{

response:
```
[{'error': {'code': -8,
'message': 'Internal addresses should not have a label'},
'success': False,
'warnings': ['Range not given, using default keypool range']},
{'success': True,
'warnings': ['Range not given, using default keypool range']}]
```
But in above, ONLY external has a label.
If you remove `internal: False` from external descriptor import object - it will import no problem:
```
[{'success': True,
'warnings': ['Range not given, using default keypool range']},
{'success': True,
'warnings': ['Range not given, using default keypool range']}]
```
Even tho it should NOT, as the descriptor is ranged. Current implementation relies on checking user provided data to decide whether desc is ranged.

Pull request description:
This PR grabs some interesting bits from https://github.com/bitcoin/bitcoin/pull/29284 and fixes some edge cases in how block tiebreaks are dealt with.
## Regarding #29284
The main functionality from the PR was dropped given it was not an issue anymore, however, reviewers pointed out some comments were outdated https://github.com/bitcoin/bitcoin/pull/29284#discussion_r1522023578 (which to my understanding may have led to thinking that there was still an issue) it also added test coverage for the aforementioned case which was already passing on master and is useful to keep.
## New functionality
While reviewing the superseded PR, it was noticed that blocks that are loaded from disk may face a similar issue (check https://github.com/bitcoin/bitcoin/pull/29284#issuecomment-1994317785 for more context).
The issue comes from how tiebreaks for equal work blocks are handled: if two blocks have the same amount of work, the one that is activatable first wins, that is, the one for which we have all its data (and all of its ancestors'). The variable that keeps track of this, within `CBlockIndex` is `nSequenceId`, which is not persisted over restarts. This means that when a node is restarted, all blocks loaded from disk are defaulted the same `nSequenceId`: 0.
Now, when trying to decide what chain is best on loading blocks from disk, the previous tiebreaker rule is not decisive anymore, so the `CBlockIndexWorkComparator` has to default to its last rule: whatever block is loaded first (has a smaller memory address).
This means that if multiple same work tip candidates were available before restarting the node, it could be the case that the selected chain tip after restarting does not match the one before.
Therefore, the way `nSequenceId` is initialized is changed to:
- 0 for blocks that belong to the previously known best chain
- 1 to all other blocks loaded from disk

Pull request description:
### Summary
Users can encounter cases where script checks are unexpectedly enabled (e.g. after reindex, or when `assumevalid`/`minimumchainwork` gates fail). Without an explicit line, they must infer state from the absence of a message, which is incomplete and error-prone.
The existing "Assuming ancestors of block …" line does not reliably indicate whether script checks are actually enabled, which makes debugging/benchmarking confusing.
### What this changes
We make the initial **script-verification** state explicit and log **why** checks are enabled to avoid confusion.
* Always log the first script-verification state on startup, **before** the first `UpdateTip`.
* Flatten the nested `assumevalid` conditionals into a linear gating sequence for readability.
* Extend the functional test to assert the old behavior with the new reason strings.
This is a **logging-only** test change it shouldn't change any other behavior.
### Example output
The state (with reason) is logged at startup and whenever the reason changes, e.g.:
* `Disabling script verification at block #904336 (000000000000000000014106b2082b1a18aaf3091e8b337c6fed110db8c56620).`
* `Enabling script verification at block #912527 (000000000000000000010bb6aa3ecabd7d41738463b6c6621776c2e40dbe738a): block too recent relative to best header.`
* `Enabling script verification at block #912684 (00000000000000000001375cf7b90b2b86e559d05ed92ca764d376702ead3858): block height above assumevalid height.`

faeb58fe66 refactor: Set G_ABORT_ON_FAILED_ASSUME when G_FUZZING_BUILD (MarcoFalke)
Pull request description:
A failing `CHECK_NONFATAL` will throw an exception. This is fine and even desired in production builds, because the program may catch the exception and give the user a way to easily report the bug upstream.
However, in debug development builds, exceptions for internal bugs are problematic:
* The exception could accidentally be caught and silently ignored
* The exception does not include a full stacktrace, possibly making debugging harder
Fix all issues by turning the exception into an abort in debug builds.
This can be tested by reverting the hunks to `src/rpc/node.cpp` and `test/functional/rpc_misc.py` and then running the functional or fuzz tests.

e9cd45e3d3 test: set number of RPC server threads to 2 (furszy)
Pull request description:
The default `-rpcthreads` value spawns 16 HTTP server threads for each node.
Running the functional test suite with default `rpcthreads` can exhaust file
descriptors or hit other resource limits very easily (more when tests are run
in parallel).
Furthermore, having 16 threads is unnecessary since they are mostly idle. We
run RPC calls on a single RPC connection and wait for it result synchronously.
There is (almost) never two RPC calls occurring concurrently.
Because of this, the threads are mostly idle, so we can safely limit the number
of them to two.
Note for reviewers:
I checked this does not introduce any timing regression but would be good
to double-check it on your end too. We could add another thread if needed.
Just the 16 threads default value is too high and unnecessary.

This PR implements MuSig2 signing so that the wallet can receive and spend from imported `musig(0` descriptors.
The libsecp musig module is enabled so that it can be used for all of the MuSig2 cryptography.
Secnonces are handled in a separate class which holds the libsecp secnonce object in a `secure_unique_ptr`. Since secnonces must not be used, this class has no serialization and will only live in memory. A restart of the software will require a restart of the MuSig2 signing process.

We currently use 21 of 32 possible bits for `SCRIPT_VERIFY_*` flags, with open PRs that may use 8 more (#29247, #31989, #32247, #32453). The mutinynet fork that has included many experimental soft fork features is [already reusing bits here](d4a86277ed/src/script/interpreter.h (L175-L195)). Therefore, bump this to 64 bits.
In order to make it easier to update this logic in future, this PR also introduces a dedicated type for the script flags, and disables implicit conversion between that type and the underlying integer type. To make verifying that this change doesn't cause flags to disappear, this PR also resurrects the changes from #28806 so that the script flags that are consensus enforced on each block can be queried via getdeploymentinfo.

576dd97cb9 test: increase timeout in p2p_leak_tx.py (Martin Zumsande)
Pull request description:
This fixes two issues with `p2p_leak_tx.py`:
1.) #33090: As far as I can see, this is just the randomness of `NextInvToInbounds`/ `rand_exp_duration`, which has a probability of `e^-(60s/5s) = 6.14×10^−6` to result in a period > 60s (our waiting time), so that the test would fail every 160k runs... Doubling the timeout should be sufficient to lower the probability drastically.
2.) The subtest `test_notfound_on_unannounced_tx` has some (w)txid confusion: we send a `MSG_TX`-type getdata with a `wtxid` in it, which necessarily always results in a NOTFOUND. Fixed this, and change the subtest to be more deterministic based on `mocktime`.

This issue exists since the merge of https://github.com/bitcoin/bitcoin/pull/28948/files#diff-97c3a52bc5fad452d82670a7fd291800bae20c7bc35bb82686c2c0a4ea7b5b98R956

When the assumevalid ancestry check fails, log a precise reason:
- "block height above assumevalid height" if the block is above the assumevalid block (the default reason)
- "block not in of assumevalid chain" otherwise
The new split was added under the existing condition to simplify conceptually that the two cases are related.
It could still be useful to know when the block is just above the assumevalid block or when it's not even on the same chain.
Update the functional test to assert the new reason strings. No behavior change.

Replaced `atomic<bool>` with `std::optional<bool>` (logged once on first observation). Safe because `ConnectBlock` holds `cs_main`.\
After this change, the state is logged before the very first `UpdateTip` line.

Increase the test to 6 nodes and add flows for baseline, deep anchor, and too-recent cases, plus scaffolding for off-best-header, not-in-assumevalid,
and reindex gates.
Assertions are minimal here; follow-ups add reason checks.

451ba9ada4 datacarrier: Undeprecate configuration option (Anthony Towns)
Pull request description:
Removes the deprecation for the `datacarrier` and `datacarriersize` options by reverting commit 0b4048c733 from https://github.com/bitcoin/bitcoin/pull/32406
**Many current Bitcoin Core users want to continue using this option**
This statement is based on public postings from many Bitcoin Core users and not a formal survey. AJ Towns’ observation from [#32406](0b4048c733 (r2084024874)) that “_for now there seem to be a bunch of users who like the option_” has only become more apparent in the months since.
**The deprecation intent is unclear to users**
This echo’s Ava Chow’s comment from #32714 that “_IMO we should not have removal warnings if there is no current plan to actually remove them._” In months since that comment, partially due to increased feedback from Bitcoin Core users wanting to keep this option, there is even less likelihood of a near term plan to remove these options. That leaves Bitcoin Core users in an unclear situation: the option could be removed in the next version or perhaps never. Removing the deprecation gives clarity for their planning purposes. Deprecating the option in the future, preferably with a removal schedule to better inform users, would still be possible.
**Minimal downsides to removing deprecation**
As a best practice, Bitcoin Core has avoided an option when the developers cannot articulate when they should be used. There is non-zero maintenance cost to keeping this code around (although leaving the options deprecated for a long time has the same effect). “Don’t offer users footguns” is also a good principle, but with this option, there seems to be only small impacts that can quickly be remedied by changing the option value by Bitcoin Core users. There already exist in Bitcoin Core more potentially-user-harmful options/values than what datacarrier might cause.

That said, certain users care strongly about using those options. In these conditions, i do not see the project removing the option anytime soon. Therefore i think it's technically incorrect (and confusing) to mark it as deprecated. utACK 451ba9ada4 on removing the deprecation.

fabc2615af test: Use extra_port() helper in feature_bind_extra.py (MarcoFalke)
Pull request description:
This is a refactor for self-validating and self-documenting code.
Currently, the test assumes that extra ports are available and just increments them without checking. However, this may not be the case when the test is modified to use more ports. In this case, the tests may fail intermittently and the failure is hard to debug.
Fix this confusion, by calling `p2p_port` each time. This ensures the required `assert n <= MAX_NODES` is checked each time.

By using mocktime, we will always hit both the notfound
branch and the tx sent branch.
The previous version didn't achieve that due to timing
issues.

With a low but not negligible probability in the order
of 10^-6 the exponential timer NextInvToInBounds can lead
to an interval >60s, making the test fail.
Also uses mocktime to speed up the test and fixes a
non-matching on_inv override.

Depending on the host machine, a default `par` value can spawn up to 15 script verification threads for each node.
Running the functional test suite with default `par` can exhaust file descriptors or hit other resource limits when many threads are spawned.
These threads are mostly idle and the same code paths are executed with a value of `par=2`.
Limit this to 2 for functional tests that do not override the default option.

75e6984ec8 test/refactor: use test deque to avoid quadratic iteration (Lőrinc)
Pull request description:
Extracted from https://github.com/bitcoin/bitcoin/pull/33141#discussion_r2323012972.
-----
In Python, [list `pop(0)` is linear](https://docs.python.org/3/tutorial/datastructures.html#using-lists-as-queues), so consuming all items in the test results in quadratic iteration.
Switching to `collections.deque` with `popleft()` expresses FIFO intent and avoids the O(n^2) path.
Behavior is unchanged - for a few hundred items the perf impact is likely negligible.

0972f55040 init: add exe name to bitcoind, bitcoin-node -version output to be able to distinguish these in tests (Ryan Ofsky)
Pull request description:
This change makes the `bitcoin` command respect IPC command line options and _bitcoin.conf_ settings, so IPC listening can be enabled by just running `bitcoin node -ipcbind=unix` or `bitcoin node` with `ipcbind=unix` in the configuration file, and there is no longer a need to specify a multiprocess `-m` option like `bitcoin -m node [...]`
sipa and theuni in #31802 pointed out that users shouldn't be exposed to multiprocess implementation details just to use IPC features, so current need to specify the `bitcoin -m` option in conjunction with `-ipcbind` could be seen as a design mistake and not just a usage inconvenience.
This PR also adds a dedicated functional test for the `bitcoin` wrapper command and to make sure it calls the right binaries and test the new functionality.

df67bb6fd8 test: Remove convert_to_json_for_cli (Ava Chow)
44a493e150 cli: Allow arguments to be both strings and json (Ava Chow)
Pull request description:
There are some RPCs where the argument can be either JSON that needs to be parsed, or a string that we can pass straight through. However, `bitcoin-cli` would always parse those arguments as JSON which makes for some cumbersome argument passing when using those RPCs. Notably, `hash_or_height` in `getblockstats` and `gettxoutsetinfo` do this, and results in a more cumbersome command of `bitcoin-cli getblockstats '"<hash>"'`. Otherwise, using a normal invocation of `bitcoin-cli getblockstats <hash>` results in `error: Error parsing JSON`. This PR marks those particular options as also being a string so that when `bitcoin-cli` fails to parse the argument as JSON, it will assume that the argument is a string and pass it straight through.

bf7996cbc3 rpc: fix getblock(header) returns target for tip (Sjors Provoost)
4c3c1f42cf test: add block 2016 to mock mainnet (Sjors Provoost)
Pull request description:
A `target` field was added to the `getblock` and `getblockheader` RPC calls in #31583, but it mistakingly always used the tip value.
This PR fixes it to return the target for the given block. Because regtest does not have difficulty adjustment, the mainnet test is expanded to cover the fix.
A preliminary commit deals with mining block 2016 that's needed for the test. It also:
- renames the `create_coinbase` `retarget_period` argument to `halving_period`. Before #31583 this was hardcoded for regtest where these values are the same.
- drops unused `fees` argument from `mine` helper
- expands the CPU miner instructions for generating the alternative mainnet chain

88b0647f02 wallet: Always write last hardened cache flag in migrated wallets (Ava Chow)
8a08eef645 tests: Check that the last hardened cache upgrade occurs (Ava Chow)
Pull request description:
#32597 set the descriptor cache upgraded flag for newly created wallets, but migrated wallets still did not have the flag set when they are migrated. For consistency, and to avoid an unnecessary upgrade, we should be setting this flag for migrated wallets.
The flag would end up being set anyways at the end of migration when the wallet is reloaded as it would perform the automatic upgrade at that time. However, this is unnecessary and we should just set it from the get go.
This PR also adds a couple tests to verify that the flag is being set, and that the upgrade is being performed.
