917a89a814 test: use MiniWallet for p2p_segwit.py (Sebastian Falbesoner)
Pull request description:
This PR enables one more of the non-wallet functional tests (p2p_segwit.py) to be run even with the Bitcoin Code wallet by using the MiniWallet instead, as proposed in https://github.com/bitcoin/bitcoin/issues/20078.
This change only affects the subtest `test_superfluous_witness`. Note that instead of creating a raw transaction first and then signing it, we go the other direction here: MiniWallet creates a transaction spending a segwit v1 output (i.e. including a witness), then we turn it into a raw transaction by dropping the witness. Therefore, the debug log asserts are swapped.

47b66ac4ac lint: Convert Python linter to Python (Fabian Jahr)
Pull request description:
The outputs provided by the Python version should be exactly the same as the ones from the shell version.
There is small improvement here: Previously only the dependency of `flake9` was checked, now all dependencies are checked before running.
I also tried to mostly follow the [recommendations here](https://github.com/bitcoin/bitcoin/pull/24766#pullrequestreview-932953476) but happy to make more changes if there is still room for improvement.

0359d9b6a3 Change wallet validation order (w0xlt)
Pull request description:
In the current code, the database is created before the last validation, which checks that passphrase is set and private keys are disabled.
Therefore, if this validation fails, it will result in an empty database and the user will not be able to recreate a wallet with the same name and with the correct parameters.
Behavior on the master branch:
```
$ ./src/bitcoin-cli -regtest -named createwallet wallet_name="invalid_wallet_01" disable_private_keys=true passphrase="passphrase"
error code: -4
error message:
Passphrase provided but private keys are disabled. A passphrase is only used to encrypt private keys, so cannot be used for wallets with private keys disabled.
$ ./src/bitcoin-cli -regtest -named createwallet wallet_name="invalid_wallet_01"

Trying to disable a wallet flag with `setwalletflag` results in `Internal bug detected: 'std::any_of(m_results.m_results.begin(), m_results.m_results.end(), [ret](const RPCResult& res) { return res.MatchesType(ret); })'`. This occurs because the `warnings` field was not marked as optional. This PR makes `warnings` optional to avoid this error.

This PR adds a very basic test for the signet miner script (contrib/signet/miner). ~~It was based on #24553 (merged by now) which fixes a bug (and was also the motivation to write this test).~~
The test roughly follows the steps from https://en.bitcoin.it/wiki/Signet#Custom_Signet, except that the challenge key-pair is created solely with the test framework. Calibration is also skipped, the difficulty is simply set to the first mainnet target `0x1d00ffff` (see also https://bitcoin.stackexchange.com/a/57186).

Pull request description:
This converts one of the linter scripts to Python. Reference issue: https://github.com/bitcoin/bitcoin/issues/24783
The approach is to just call git grep using subprocess.run.
Alternative approaches could be to use Python instead of git grep (I'm not sure how) or use ```pylint --disable=all --enable=W0102```, though that requires installation of pylint.

This PR enables one more of the non-wallet functional tests (feature_fee_estimation.py) to be run even with the Bitcoin Core wallet disabled by using the MiniWallet instead, as proposed in https://github.com/bitcoin/bitcoin/issues/20078. It takes use of the recently introduced methods `{create,send}_self_transfer_multi` (#24637) which allows to specify multiple UTXOs to be spent rather than only one. Very likely the test can still be simplified (e.g. coin selection in `small_txpuzzle_randfee`), but this is a first step.

4394733331 Add DEBUG_LOCKCONTENTION documentation to the developer notes (Jon Atack)
39a34b6877 Put lock logging behind DEBUG_LOCKCONTENTION preprocessor directive (Jon Atack)
Pull request description:
This is a more minimal, no-frills version of #24734 for backport. The other fixes and improvements in that pull can be done after.
*Copy of the PR 24734 description:*
PRs #22736, #22904 and #23223 changed lock contention logging from a `DEBUG_LOCKCONTENTION` compile-time preprocessor directive to a runtime `lock` log category and improved the logging output. This changed the locking from using `lock()` to `try_lock()`:
- `void Mutex::UniqueLock::lock()` acquires the mutex and blocks until it gains access to it
- `bool Mutex::UniqueLock::try_lock()` doesn't block but instead immediately returns whether it acquired the mutex; it may be used by `lock()` internally as part of the deadlock-avoidance algorithm
In theory the cost of `try_lock` might be essentially the [same](https://www.erisian.com.au/bitcoin-core-dev/log-2022-03-31.html#l-697) relative to `lock`. The test-and-set logic of these calls is purported to be ~ constant time, optimised and light/quick if used carefully (i.e. no mutex convoying), compared to system calls, memory/cache coherency and fences, wait queues, and (particularly) lock contentions. See the discussion around https://github.com/bitcoin/bitcoin/pull/22736#issuecomment-902851054 and after with respect to performance/cost aspects. However, there are reasonable concerns (see [here](https://github.com/bitcoin/bitcoin/pull/22736#discussion_r691277896) and [here](https://www.erisian.com.au/bitcoin-core-dev/log-2022-03-31.html#l-620)) that `Base::try_lock()` may be potentially [costly](https://www.erisian.com.au/bitcoin-core-dev/log-2022-03-31.html#l-700) or [risky](https://github.com/bitcoin/bitcoin/pull/22904#issuecomment-930484001) compared to `Base::lock()` in this very frequently called code.
One alternative to keep the run-time lock logging would be to gate the `try_lock` call behind the logging conditional, for example as proposed in ccd73de1dd and ACKed [here](https://github.com/bitcoin/bitcoin/pull/22736#issuecomment-901980815). However, this would add the [cost](https://github.com/bitcoin/bitcoin/pull/22736#issuecomment-910102353) of `if (LogAcceptCategory(BCLog::LOCK))` to the hotspot, instead of replacing `lock` with `try_lock`, for the most frequent happy path (non-contention).
It turns out we can keep the advantages of the runtime lock contention logging (the ability to turn it on/off at runtime) while out of prudence putting the `try_lock()` call and `lock` logging category behind a `DEBUG_LOCKCONTENTION` compile-time preprocessor directive, and also still retain the lock logging enhancements of the mentioned PRs, as suggested in https://github.com/bitcoin/bitcoin/pull/24734#issuecomment-1085785480 by W. J. van der Laan, in https://github.com/bitcoin/bitcoin/pull/22736#discussion_r691280693, and in the linked IRC discussion.
Proposed here and for backport to v23.

Additionally, three other cleanups/improvements are done:
- import script operator constants `OP_*` from test framework instead of manually defining them
- add Python path to test framework directly in the script (via `sys.path.append(...)`) instead of needing the caller to specify `PYTHONPATH=...` on the command line (the same approach is done for the signet miner and the message capture scripts)
- rename `chars` to `b58chars` in the test_framework.address module (is more explicit and makes the diff for the base58 replacement smaller)

Pull request description:
This adds functional tests for the USDT tracepoints added in https://github.com/bitcoin/bitcoin/pull/22006 and https://github.com/bitcoin/bitcoin/pull/22902. This partially fixes#23296. The tests **are probably skipped** on most systems as these tests require:
- a Linux system with a kernel that supports BPF (and available kernel headers)
- that Bitcoin Core is compiled with tracepoints for USDT support (default when compiled with depends)
- [bcc](https://github.com/iovisor/bcc) installed
- the tests are run with a privileged user that is able to e.g. do BPF syscalls and load BPF maps
The tests are not yet run in our CI as the CirrusCI containers lack the required permissions (see https://github.com/bitcoin/bitcoin/issues/23296#issuecomment-1024920845). Running the tests in a VM in the CI could work, but I haven't experimented with this yet. The priority was to get the actual tests done first to ensure the tracepoints work as intended for the v23.0 release. Running the tracepoint tests in the CI is planned as the next step to finish #23296.
The tests can, however, be run against e.g. release candidates by hand. Additionally, they provide a starting point for tests for future tracepoints. PRs adding new tracepoint should include tests. This makes reviewing these PRs easier.
The tests require privileges to execute BPF sycalls (`CAP_SYS_ADMIN` before Linux kernel 5.8 and `CAP_BPF` and `CAP_PERFMON` on 5.8+) and permissions to `/sys/kernel/debug/tracing/`. It's currently recommended to run the tests in a virtual machine (or on a VPS) where it's sensible to use the `root` user to gain these privileges. Never run python scripts you haven't carefully reviewed with `root` permissions! It's unclear if a non-root user can even gain the required privileges. This needs more experimenting.
The goal here is to test the tracepoint interface to make sure the [documented interface](https://github.com/bitcoin/bitcoin/blob/master/doc/tracing.md#tracepoint-documentation) does not break by accident. The tracepoints expose implementation details. This means we also need to rely on implementation details of Bitcoin Core in these functional tests to trigger the tracepoints. An example is the test of the `utxocache:flush` tracepoint: On Bitcoin Core shutdown, the UTXO cache is flushed twice. The corresponding tracepoint test expects two flushes, too - if not, the test fails. Changing implementation details could cause these tests to fail and the tracepoint API to break. However, we purposefully treat the tracepoints only as [**semi-stable**](https://github.com/bitcoin/bitcoin/blob/master/doc/tracing.md#semi-stable-api). The tracepoints should not block refactors or changes to other internals.

cccc4e879a Remove nHeightEnd and nHeight in generateBlocks helper (MarcoFalke)
fa38b1c8bd Remove buggy and confusing IncrementExtraNonce (MarcoFalke)
Pull request description:
IncrementExtraNonce has many issues:
* It is test-only code, but part of bitcoind
* It is using the block height of the tip, as opposed to the block's previous block as reference for the new height. See https://github.com/bitcoin/bitcoin/issues/24730#issuecomment-1085586193
* It has no use case in regtest testing. With a low difficulty the extra nonce won't be incremented. With a high difficulty the test-only functions are clumsy to handle anyway. For example, the generate* RPCs will return an empty array once they reached `maxtries`, as opposed to an error. Also the calls can't be aborted early unless the node shuts down completely. So I think it is fine to just remove the extra nonce functionality and leave it to the outside to implement, if needed. For example, a wrapper script can call the `generate*` RPCs once every second, to use the timestamp as extra nonce.

Pull request description:
In RESTful APIs, [typically](https://rapidapi.com/blog/api-glossary/parameters/query/) path parameters (e.g. `/some/unique/resource/`) are used to represent resources, and query parameters (e.g. `?sort=asc`) are used to control how these resources are being loaded through e.g. sorting, pagination, filtering, ...
As first [discussed in #17631](https://github.com/bitcoin/bitcoin/pull/17631#discussion_r733031180), the [current REST api](https://github.com/bitcoin/bitcoin/blob/master/doc/REST-interface.md) contains two endpoints `/headers/` and `/blockfilterheaders/` that rather unexpectedly use path parameters to control how many (filter) headers are returned in the response. While this is no critical issue, it is unintuitive and we are still early enough to easily phase this behaviour out and ensure new endpoints (if any) do not have to stick to non-standard behaviour just for internal consistency.
In this PR, a new `HTTPRequest::GetQueryParameter` method is introduced to easily parse query parameters, as well as two new `/headers/` and `/blockfilterheaders/` endpoints that use a count query parameter are introduced. The old path parameter-based endpoints are kept without too much overhead, but the documentation now points to the new query parameter-based endpoints as the default interface to encourage standardness.
## Behaviour change
### New endpoints and default values
`/headers/` and `/blockfilterheaders/` now have 2 new endpoints that contain query parameters (`?count=<count>`) instead of path parameters (`/<count>/`), as described in REST-interface.md. Since query parameters can easily have default values, I have set this at 5 for both endpoints.
**headers**
`GET /rest/headers/<BLOCK-HASH>.<bin|hex|json>?count=<COUNT=5>`
should now be used instead of
`GET /rest/headers/<COUNT>/<BLOCK-HASH>.<bin|hex|json>`
**blockfilterheaders**
`GET /rest/blockfilterheaders/<FILTERTYPE>/<BLOCK-HASH>.<bin|hex|json>?count=<COUNT=5>`
should now be used instead of
`GET /rest/blockfilterheaders/<FILTERTYPE>/<COUNT>/<BLOCK-HASH>.<bin|hex|json>`
### Some previously invalid API calls are now valid
API calls that contained query strings in the URI could not be parsed prior to this PR. This PR changes behaviour in that previously invalid calls (e.g. `GET /rest/headers/5/somehash.json?someunusedparam=foo`) would now become valid, as the query parameters are properly parsed, and discarded if unused.
For example, prior to this PR, adding an irrelevant `someparam` parameter would be illegal:
```
GET /rest/headers/5/0000004c6aad0c89c1c060e8e116dcd849e0554935cd78ff9c6a398abeac6eda.json?someparam=true
->
Invalid hash: 0000004c6aad0c89c1c060e8e116dcd849e0554935cd78ff9c6a398abeac6eda.json?someparam=true
```
**This behaviour change affects all rest endpoints, not just the 2 new ones introduced here.**
*(Note: I'd be open to implementing additional logic to refuse requests containing unrecognized query parameters to minimize behaviour change, but for the endpoints that we currently have I don't really see the point for that added complexity. E.g. I don't see any scenarios where misspelling a parameter could lead to harmful outcomes)*
## Using the REST API
To run the API HTTP server, start a bitcoind instance with the `-rest` flag enabled. To use the
`blockfilterheaders` endpoint, you'll also need to set `-blockfilterindex=1`:
```
./bitcoind -signet -rest -blockfilterindex=1
```
As soon as bitcoind is fully up and running, you should be able to query the API, for example by
using curl on the command line: ```curl "127.0.0.1:38332/rest/chaininfo.json"```.
To more easily parse the JSON output, you can also use tools like 'jq' or `json_pp`, e.g.:
```
curl -s "localhost:38332/rest/blockfilterheaders/basic/0000004c6aad0c89c1c060e8e116dcd849e0554935cd78ff9c6a398abeac6eda.json?count=2" | json_pp .
```

In most RESTful APIs, path parameters are used to represent resources, and
query parameters are used to control how these resources are being filtered/sorted/...
The old /<count>/ functionality is kept alive to maintain backwards compatibility,
but new paths with query parameters are introduced and documented as the default
interface so future API methods don't break consistency by using query parameters.
fa9112aac0 Remove utxo db upgrade code (MarcoFalke)
Pull request description:
It is not possible to upgrade Bitcoin Core pre-segwit (pre-0.13.1) to a recent version without a full IBD from scratch after commit 19a56d1519 (released in version 22.0).
Any Bitcoin Core version with the new database format after commit 1088b02f0c (released in version 0.15), can upgrade to any version that is supported as of today.
This leaves the versions 0.13.1-0.14.x. Even though those versions are unsupported, some users with an existing datadir may want to upgrade to a recent version. However, it seems reasonable to simply ask them to `-reindex` to run a full IBD from scratch. This allows us to remove the utxo db upgrade code.

17648493df doc: Speed up functional test runs using ramdisk (willcl-ark)
Pull request description:
Using a ramdisk for the functional tests can give noticable speedups for developers and reviewers.
Local testing with an 8GB ramdisk saw a full test run using `test/functional/test_runner.py --jobs=100 --cachedir=/mnt/tmp/cache --tmpdir=/mnt/tmp` reduced from ~280 seconds to ~99 seconds.
Possible bikeshedding opportunity to be had over whether this might best fit into `doc/productivity.md`, but IMO more people will likely see it (and it will therefore be more useful) if it is here.
It seems best to select `tmpfs` over `ramfs` as `ramfs` can grow dynamically (good) but cannot be limited in size and might cause the system to hang if you run out of ram (bad), whereas `tmpfs` is size-limited and will overflow into swap.

Pull request description:
Add sendall RPC née sweep
_Motivation_
Currently, the wallet uses a fSubtractFeeAmount (SFFO) flag on the
recipients objects for all forms of sending calls. According to the
commit discussion, this flag was chiefly introduced to permit sweeping
without manually calculating the fees of transactions. However, the flag
leads to unintuitive behavior and makes it more complicated to test
many wallet RPCs exhaustively. We proposed to introduce a dedicated
`sendall` RPC with the intention to cover this functionality.
Since the proposal, it was discovered in further discussion that our
proposed `sendall` rpc and SFFO have subtly different scopes of
operation.
• sendall:
Use _given UTXOs_ to pay a destination the remainder after fees.
• SFFO:
Use a _given budget_ to pay an address the remainder after fees.
While `sendall` will simplify cases of spending a given set of
UTXOs such as paying the value from one or more specific UTXOs, emptying
a wallet, or burning dust, we realized that there are some cases in
which SFFO is used to pay other parties from a limited budget,
which can often lead to the creation of change outputs. This cannot be
easily replicated using `sendall` as it would require manual
computation of the appropriate change amount.
As such, sendall cannot replace all uses of SFFO, but it still has a
different use case and will aid in simplifying some wallet calls and
numerous wallet tests.
_Sendall call details_
The proposed sendall call builds a transaction from a specific
subset of the wallet's UTXO pool (by default all of them) and assigns
the funds to one or more receivers. Receivers can either be specified
with a given amount or receive an equal share of the remaining
unassigned funds. At least one recipient must be provided without
assigned amount to collect the remainder. The `sendall` call will
never create change. The call has a `send_max` option that changes the
default behavior of spending all UTXOs ("no UTXO left behind"), to
maximizing the output amount of the transaction by skipping uneconomic
UTXOs. The `send_max` option is incompatible with providing a specific
set of inputs.

Using a ramdisk for the functional tests can give worthwhile speed-ups
for developers and reviewers.
Add notes to test/README.md on how to setup, use and erase a ramdisk on
Linux.
