efae252f3072da598160670691757a0d60b9beb4 test: Remove extended lint (cppcheck) (laanwj)
Pull request description:
These are unreferenced in the CI and documentation, and have been since 2019 (see #17549).
I'm not sure the cppcheck is worthwhile. It takes a long time to run (I think this is why it isn't in the normal lints), and right
now it only appears to find implicit constructors. The list of exceptions is out of date. But if anyone wants to bring it back at any
time in the future they can do so from git history (and port it to Python).

bitcoin#25454 introduces a 10 point penalty for remitting more than
MAX_BLOCKS_TO_ANNOUNCE unconnected block headers. Whether they are
connected or not is determined by taking the first entry and running
its hashPrevBlock through LookupBlockIndex. This new behaviour causes a
test failure in p2p_dos_header_tree.py in Dash.
Bitcoin doesn't face a test failure with this new behaviour as the first
non-fork block in its test data is the dump for block 1 (00000000b873e7
9784647a6c82962c70d228557d24a747ea4d1b8bbe878e1206) but Dash uses block
0 (00000bafbc94add76cb75e2ec92894837288a481e5c005f6563d91623bf8bc2c),
the genesis block.
By definition of a genesis block, it has a hashPrevBlock of 0, which
cannot be looked up. This trips the penalty. This doesn't cause any
problems in the field as nobody is expected to ever broadcast the
genesis block but it does cause a test failure for us.
We need to correct that by getting rid of the genesis block from the
test data.

38ecd6f951 test: reduce BRRHeight on regtest (Odysseas Gabrielides)
Pull request description:
## Issue being fixed or feature implemented
In regtest, Block Reward Reallocation is buried at height 2500, which happens after v20 activation.
## What was done?
Reduced BRRHeight in regtest from 2500 to 1000.
The purpose of this change is to simplify regtests of Platform as well.
Note: This change affects only regtest.
## How Has This Been Tested?
tests
## Breaking Changes
no, this only affects Regtest (where we make no guarantees about breaking stuff)

1fb67ece0e feat: make a support of Qt app to show Platform Transfer transaction as a new type of transaction (Konstantin Akimov)
Pull request description:
## Issue being fixed or feature implemented
Transfers from platform have incorrectly shown amount in Dash Core wallet app.
They also shown in Qt app as self-send that is not completely true.
## What was done?
Added new type of transaction to Qt App, added a filter for its type, fixed calculation of output for tx records.
As well added a new type of transaction `platform-transfer` in rpc output of `gettransaction` RPC
## How Has This Been Tested?
Make a Platform Transfer transaction on RegTest and check it in Dash Core
Helper to see it: export dpath=/tmp/dash_func_test_PATHPATH/ ; src/qt/dash-qt -regtest -conf=$dpath/node0/dash.conf -datadir=$dpath/node0/ -debug=0 -debuglogfile=/dev/stdout
## Breaking Changes
There's new type of transaction "platform-transfer" in rpc output of `gettransaction`.
**This PR DOES NOT change any consensus rules.**
Breaking changes that makes withdrawal transaction immature is moved to https://github.com/dashpay/dash/pull/6128

a2fe2b27d9 test: minor improvements for credit pool functional test (Konstantin Akimov)
Pull request description:
## Issue being fixed or feature implemented
DIP for Credit Pool says:
```
The withdrawal should not be mined if:
* It requests more DASH than the credit pool contains
* It requests more than 1000 DASH
* The credit pool contains more than 1000 DASH, and the withdrawal would result in more than a 10% reduction in the credit pool over the 576-block window
* The credit pool contains less than 1000 DASH, and the withdrawal would result in more than 100 DASH being removed from the pool over the 576-block window
```
Though, current functional test for asset locks improperly test this case, because threshold for big withdrawal happens by 10%, not 1000 dash.
## What was done?
Improvements for functional asset lock test to actually test a limit 1000 dash, not just 10%
## How Has This Been Tested?
See changes
## Breaking Changes
N/A, changes only for tests

Pull request description:
This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).
---
This PR adds basic process spawning and IPC method call support to `bitcoin-node` executables built with `--enable-multiprocess`[*].
These changes are used in https://github.com/bitcoin/bitcoin/pull/10102 to let node, gui, and wallet functionality run in different processes, and extended in https://github.com/bitcoin/bitcoin/pull/19460 and https://github.com/bitcoin/bitcoin/pull/19461 after that to allow gui and wallet processes to be started and stopped independently and connect to the node over a socket.
These changes can also be used to implement new functionality outside the `bitcoin-node` process like external indexes or pluggable transports (https://github.com/bitcoin/bitcoin/pull/18988). The `Ipc::spawnProcess` and `Ipc::serveProcess` methods added here are entry points for spawning a child process and serving a parent process, and being able to make bidirectional, multithreaded method calls between the processes. A simple example of this is implemented in commit "Add echoipc RPC method and test."
Changes in this PR aside from the echo test were originally part of #10102, but have been split and moved here for easier review, and so they can be used for other applications like external plugins.
Additional notes about this PR can be found at https://bitcoincore.reviews/19160
[*] Note: the `--enable-multiprocess` feature is still experimental, and not enabled by default, and not yet supported on windows. More information can be found in [doc/multiprocess.md](https://github.com/bitcoin/bitcoin/blob/master/doc/multiprocess.md)

6cebac598e5e85eadd60eb1274d7f33d63ce1108 test: MiniWallet: introduce enum type for output mode (Sebastian Falbesoner)
Pull request description:
This is a follow-up PR to #21945 which lifted the number of MiniWallet's tx output modes from 2 to 3 (by adding P2PK Support).
Since the current way of specifying the mode on the ctor via two booleans is ugly and error-prone (see table in comment https://github.com/bitcoin/bitcoin/pull/21945#issuecomment-842526575), a new Enum type `MiniWalletMode` is introduced that can hold the following values:
- ADDRESS_OP_TRUE
- RAW_OP_TRUE
- RAW_P2PK
Also adds documentation that should guide the user on which mode is useful for what etc. with a summary table. (Can also be split up in a separate commit or shortened if that is desired, maybe it's considered to be too verbose).

Pull request description:
This PR adds support for creating and spending transactions with raw pubkey (P2PK) outputs to MiniWallet, [as suggested by MarcoFalke](https://github.com/bitcoin/bitcoin/pull/21900#discussion_r629524841). Using that mode in the test `feature_csv_activation.py`, all txs submitted to the mempool follow the standard policy, i.e. `-acceptnonstdtxn=1` can be removed.
Possible follow-ups:
* Improve MiniWallet constructor Interface; an enum-like parameter instead of two booleans would probably be better
* Look at other tests that could benefit from P2PK (e.g. feature_cltv.py?)
* Check vsize also for P2PK txs (vsize varies due to signature, i.e. a range has to be asserted)

2eca46b0aa0ecf4738500b53523d7013985b387d test: use MiniWallet for feature_csv_activation.py (Sebastian Falbesoner)
Pull request description:
This PR enables one more of the non-wallet functional tests (feature_csv_activation.py) to be run even with the Bitcoin Core wallet disabled by using the new MiniWallet instead, as proposed in #20078.
Short reviewers guideline:
- Since we exclusively work with anyone-can-spend outputs here (raw scriptPubKey = OP_TRUE), signing is not needed anymore. The function `sign_transaction` and its calls are removed, after changing a tx (e.g. its scriptSig or nVersion) a simple `.rehash()` call is sufficient. Also, generating an address `self.nodeaddress` (and with that, passing it to the the various test tx creation/sending helper methods) is not needed anymore and removed.
- The test repeatedly uses the same input for creating different txs (e.g. with different txversions 1 and 2). To let `MiniWallet` create a tx with a specific input, we have to call `.get_utxo()` before which also marks the UTXO as spent. The method is changed to also support keeping the UTXO in its internal list (`mark_as_spent=False`). With the behaviour on master, the second call to `.get_utxo()` with the same input would fail.
- To keep the diff in the first commit short, the `miniwallet` is set as a global variable, to avoid passing it on every tx creation/spending helper. The global is eliminated in the second (refactoring) commit, where all the helpers are moved to the test class as methods. By that, we can use `self.nodes[0]` directly in the helpers and don't have to pass it again and again. I think there could still be a lot of improvements/refactoring done in the test, but that should hopefully serve as a good basis.

This PR enables one more of the non-wallet functional tests (p2p_blocksonly.py) to be run even with the Bitcoin Core wallet disabled by using the new MiniWallet instead, as proposed in #20078.
Note that MiniWallet creates segwit transactions by default, i.e. txid and wtxid are not identical and we have to return both from `check_p2p_tx_violation(...)`: wtxid is needed to match an expected `"received getdata for: wtx ..."` debug output, whereas the txid is needed to wait for a certain tx via `wait_for_tx(...)`.

Pull request description:
This tiny PR cleans up the test `feature_cltv.py` in the following ways:
* fixes a typo (s/ctlv/cltv/); compared to CHECKLOCKTIMEVERIFY, CHECKTIMELOCKVERIFY probably also sounds good and you [even get some search results for it](https://www.google.com/search?q=%22CHECKTIMELOCKVERIFY%22), but it's still wrong ;)
* drops the unused "node" parameters from the tx modification functions
* don't return a copy from the tx modification functions; it's modified in-place, hence a copy is not needed and `cltv_validate(tx, ...)` looks more natural than `tx = cltv_validate(tx, ...)`

6bb54708e6457f21596793a7149dc6dfea1dc871 util: Check if specified config file cannot be opened (nthumann)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/22612.
When running e.g. `./src/bitcoind -datadir=/tmp/bitcoin -regtest -conf=/tmp/bitcoin/regtest/bitcoin.conf` and the specified config cannot be opened (doesn't exist, permission denied, ...), the initialization silently uses the default config.
As voidburn already noted:
> I can't think of a situation in which a config file is specified explicitly (in the startup options, as per service unit linked above), but inaccessible, where the fail condition should be to keep booting using defaults instead.
With this patch applied, the initialization will fail immediately, if the specified config file cannot be opened. If no config file is explicitly specified, the behavior is unchanged. This not only affects `bitcoind`, but also `bitcoin-cli` and `bitcoin-qt`.
In the example below the datadir is accessible, but the config file is not due to insufficient permissions:
```
$ ./src/bitcoind -datadir=/tmp/bitcoin -regtest --debug=1 -conf=/tmp/bitcoin/regtest/bitcoin.conf
Error: Error reading configuration file: specified config file "/tmp/bitcoin/regtest/bitcoin.conf" could not be opened.

* In [bitcoin#24050](https://github.com/bitcoin/bitcoin/pull/24050), `BlockMap` is given ownership of the `CBlockIndex` instance contained within the `unordered_map`. The same has not been done for `PrevBlockMap` as `PrevBlockMap` is populated with `pprev` pointers and doing so seems to break validation logic.
* Dash has a specific linter for all Dash-specific code present in Core. The introduction of `util/translation.h` into `validation.h` has caused the linter to trigger shadowing warnings due to a conflict between the common use of `_` as a placeholder/throwaway name ([source](37e026a038/src/spork.cpp (L44))) and upstream's usage of it to process translatable strings ([source](37e026a038/src/util/translation.h (L55-L62))).
Neither C++17 nor C++20 have an _official_ placeholder/throwaway term or annotation for structured bindings (which cannot use `[[maybe_unused]` or `std::ignore`) but [P2169](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2023/p2169r4.pdf) is a proposal put forth to make it the official placeholder, in that light, the linter will silence shadowing warnings involving an underscore.

Bitcoin uses underscore in util/translation.h for translatable strings
but underscores are also a placeholder used in multiple languages, incl.
C++. The next commit will be introducing backports, one of them will be
placing util/translation.h into validation.h, which is a header used by
Dash-specific code.
This causes a conflict between the normal usage of underscore as a
placeholder and Bitcoin's usage of it as a function name, which is
reported by the Dash-specific linter. We need to exclude shadowing
warnings from the linter to account for this.

Pull request description:
The functional test for [BIP65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki) / `OP_CHECKLOCKTIMEVERIFY` (`feature_cltv.py`) currently only tests one out of five conditions that lead to failure of the op-code -- by prepending the script `OP_1NEGATE OP_CHECKLOCKTIMEVERIFY OP_DROP` to a tx's first input's scriptSig, the case of "_the top item on the stack is less than 0_" is checked:
f8462a6d27/test/functional/feature_cltv.py (L26-L35)
This PR adds the other cases (5 in total) by taking an integer argument to the function `cltv_invalidate` that is called in a loop instead of only once per testing scenario. Here is the full list of failure conditions and how they are tested (note that the scriptSig should still be valid before activation of BIP65, when `OP_CLTV` is simply a no-op):
* _the stack is empty_
➡️ prepending `OP_CHECKLOCKTIMEVERIFY` to scriptSig
* _the top item on the stack is less than 0_
➡️ prepending `OP_1NEGATE OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
* _the lock-time type (height vs. timestamp) of the top stack item and the nLockTime field are not the same_
➡️ prepending `OPNum(1000) OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
➡️ setting tx.vin[0].nSequence=0 and tx.nCheckTimeLock=1296688602 (genesis block timestamp)
* _the top stack item is greater than the transaction's nLockTime field_
➡️ prepending `OPNum(1000) OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
➡️ setting tx.vin[0].nSequence=0 and tx.nCheckTimeLock=500
* _the nSequence field of the txin is 0xffffffff_
➡️ prepending `OPNum(500) OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
➡️ setting tx.vin[0].nSequence=0xffffffff and tx.nCheckTimeLock=500
The first commit creates a helper function for the tx modification and also includes some tidying up like turning single-line to multi-line Python imports where necessary and cleaning up some PEP8 warnings. The second commit prepares the invalidation function `cltv_invalidate` and the third and the fourth use it and check for the expected reject reason strings ("Operation not valid with the current stack size", "Negative locktime" and "Locktime requirement not satisfied").

06e1fb0b170a69996a7ce1ef5203785a7bc6b278 Add new format string placeholders for walletnotify to include relevant block information for transactions (Maayan Keshet)
Pull request description:
This patch includes two new format placeholders for walletnotify:
%b - the hash of the block containting the transaction (zeroed if a mempool transaction)
%h - the height of the block containing the transaction (zero if a mempool transaction)
I've included test suite changes to check and validate the above functional requirements as well as doc/help description changes.
**Motivation**
The walletnotify option is used to be notified of new transactions relevant to the wallet of the node.
A common usage pattern is to perform afterwards additional RPC calls to determine:
1. If this is a mempool transaction or not (i.e. are there any confirmations?)
2. What block was it included in?
3. Did this transaction was seen before and is now seen again because of a fork?
All of these questions can be answered with the current features, but the resulting RPC calls may be expensive in a heavily used node. As this information is readily available when calling the walletnotify callback, it makes sense to save expensive round trips by optionally sending this information at that point in time. I can definitely say we would like to use it in Fireblocks, my employer.
Please let me know of any questions and suggestions.

Pull request description:
## Issue being fixed or feature implemented
Backports from bitcoin v22 rpc command related
## What was done?
See commits for backports.
Also:
- refactored and significantly simplified implementation of composite commands
- added missing changes from bitcoin#19250
- fix help message for rpc `help` - all subcommands support it now
- add missing client's argument parsing for RPC commands
- CoreContext uses std::monostate instead nullopt which is best-practice for std::variant
## How Has This Been Tested?
Run unit/functional tests.
Checked autocomplete for various commands
Checked help for various commands
## Breaking Changes
n/a
