02942056fd test: fix intermittent failure in p2p_orphan_handling.py (Martin Zumsande)
Pull request description:
If the mocktime is bumped before the node has successfully disconnected the peer, the requests for both parents could be spread over two GETDATAS: The first time `GetRequestsToSend` is invoked it would only request one tx from peer2, because the other one would only be available after peer1 was disconnected and its outstanding txrequest cleared.
So two GETDATAs would be sent, which would make the test fail.

fa9cf38ab6 scripted-diff: test: Rename send_message to send_without_ping (MarcoFalke)
fa4356717d test: Prefer send_and_ping over send_message+sync_with_ping (MarcoFalke)
Pull request description:
`send_message` is problematic, because it is easy to forget a `sync_with_ping` (or other `wait_until`), leading to intermittent test failures. (Example: https://github.com/bitcoin/bitcoin/pull/31837#discussion_r1950370246)
There are more uses of `send_and_ping` in the codebase than `send_message`, so in most cases `send_and_ping` is needed anyway.
For the remaining cases, clearly document that no sync happens by renaming `send_message` to `send_without_ping`.

2819c51482 test: Use rpc_deprecated only for testing deprecation (Fabian Jahr)
Pull request description:
The comment in `functional/rpc_deprecated.py` says "This test should be used to verify correct behaviour of deprecated RPC methods with and without the -deprecatedrpc flags." I think we can get rid of the "with" part since we can assume that every deprecated RPC is already tested in at least one other functional test. (I didn't look but I could verify in our coverage if someone has doubts about that.) In order for this test to continue working, the flag will need to be used there. Otherwise this seems to prescribe copy+pasting a basic test from another file and I don't see a good reason for that.

Wait until the node's process has fully stopped before starting a new instance.
Since the same code is used in tool_wallet.py, this consolidates the behavior
into a 'kill_process()' function.
send_message only drops the bytes in a buffer and a sync is needed to
avoid intermittent test issues. Change the name of the method to make
this more apparent during review.

Pull request description:
The `feature_assumeutxo.py` functional test checks various errors with malleated snapshots. Some of these cases are brittle or use confusing and undocumented values. Fix one of those by using a clear, documented and forward-compatible value.
I ran across those when working on an unrelated changeset which affected the snapshot. It took me a while to understand where the seemingly magic byte string was coming from, so i figured it was worth proposing this patch on its own for the sake of making the test more maintainable.

11f8ab140f test: wallet, coverage for crash on dup block disconnection during unclean shutdown (Martin Zumsande)
9ef429b6ae wallet: fix crash on double block disconnection (furszy)
Pull request description:
The wallet crashes if it processes the same block disconnection event twice in a row due
to an incompatible coinbase transaction state.
This happens because `disconnectBlock` provides `TxStateInactive` without the "abandoned"
flag for coinbase transactions to `SyncTransaction`, while `AddToWallet()` internally modifies
it to retain the abandoned state.
The crash flow is as follows:
1) On the first disconnection, the transaction state transitions from "confirmed" to
"inactive," bypassing the state equality check since the provided state differs. Then,
`AddToWallet` internally updates the state to "inactive + abandoned"
2) On the second disconnection, as we provide only the "inactive" state
to `SyncTransaction()`, the state equality assertion fails and crashes the wallet.
Reviewers Note:
The crash can easily be replicated by cherry-picking the test commit in master.

a3baead7cb validation: use wtxid instead of txid in CheckEphemeralSpends (marcofleon)
Pull request description:
This PR addresses a small bug in [`AcceptMultipleTransactions`](45719390a1/src/validation.cpp (L1598)) where a txid was being inserted into a map that should only hold wtxids. `CheckEphemeralSpends` has an out parameter on failure that records that the child transaction did not spend the parent's dust. Instead of using the txid of this child, use its wtxid.
The second commit in this PR is a refactor of the `PackageMempoolAcceptResult` struct to use the `Wtxid` type instead of `uint256`. This helps to prevent errors like this in the future.

026bb226e9 cmake: Set top-level target output locations (Hennadii Stepanov)
Pull request description:
This PR sets the target output locations to the `bin` and `lib` subdirectories within the build tree, creating a directory structure that mirrors that of the installed targets.
This approach is widely adopted by the large projects, such as [LLVM](e146c1867e/lldb/cmake/modules/LLDBStandalone.cmake (L128-L130)):
```cmake
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib${LLVM_LIBDIR_SUFFIX})
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib${LLVM_LIBDIR_SUFFIX})
```
The `libsecp256k1` project has also recently [adopted](https://github.com/bitcoin-core/secp256k1/pull/1553) this approach.
With this PR, all binaries are conveniently located. For example, run:
```
$ ./build/bin/fuzz
```
instead of:
```
$ ./build/src/test/fuzz/fuzz
```
On Windows, all required DLLs are now located in the same directory as the executables, allowing to run `bitcoin-chainstate.exe` (which loads `bitcoinkernel.dll`) without the need to copy DLLs or modify the `PATH` variable.
The idea was briefly discussed among the build team during the recent CoreDev meeting.

**Warning**: This PR changes build locations of newly built executables like `bitcoind` and `test_bitcoin` from `src/` to `bin/` without deleting previously built executables. A clean build is recommended to avoid accidentally running old binaries.

In the assumeutxo functional tests, the final test case with alternated UTxO data tests the error
raised when deserializing a snapshot that contains a coin with an amount not in range (<0 or
>MAX_MONEY).
The current malleation uses an undocumented byte string and offset which makes it hard to maintain.
In addition, the undocumented offset is set surprisingly high (39 bytes is well into the
serialization of the amount which starts at offset 36). Similarly the value is surprisingly small,
presumably one was adjusted for the other. But there is no comment explaining how they were chosen,
why not in a clearer manner and what they are supposed to represent.
Instead replace this seemingly magic value with a clear one, MAX_MONEY + 1, serialize the whole
value for the amount field at the correct offset, and document the whole thing for the next person
around.
Transifex interprets the "-0" substring as a number in translatable
strings. Since not all translations preserve "-0," this triggers a
corresponding warning. While this warning could be disabled globally, it
is more reasonable to adjust the original string instead.
This change:
1. Collects build artifacts in dedicated locations.
2. Allows running bitcoin-chainstate.exe with bitcoinkernel.dll directly
from the build tree on Windows.
e4dd5a351b test: wallet, abandon coinbase txs and their descendants during startup (furszy)
474139aa9b wallet: abandon inactive coinbase tx and their descendants during startup (furszy)
Pull request description:
Since #26499, we mark coinbase transactions and their descendants as abandoned when a reorg arises through the "block disconnection" signal handler. However, this does not cover all scenarios; external wallets could contain coinbase transactions from blocks the node has not seen yet, or the user could have replaced the chain with an earlier or different version (one without the coinbase chain).
This affects balance calculation as well as mempool rebroadcast (descendants shouldn't be relayed).
Fix this by marking orphaned coinbase transactions and their descendants as abandoned during wallet startup.

4080b66cbe test: add test for utxo-to-sqlite conversion script (Sebastian Falbesoner)
ec99ed7380 contrib: add tool to convert compact-serialized UTXO set to SQLite database (Sebastian Falbesoner)
Pull request description:
## Problem description
There is demand from users to get the UTXO set in form of a SQLite database (#24628). Bitcoin Core currently only supports dumping the UTXO set in a binary _compact-serialized_ format, which was crafted specifically for AssumeUTXO snapshots (see PR #16899), with the primary goal of being as compact as possible. Previous PRs tried to extend the `dumptxoutset` RPC with new formats, either in human-readable form (e.g. #18689, #24202), or most recently, directly as SQLite database (#24952). Both are not optimal: due to the huge size of the ever-growing UTXO set with already more than 80 million entries on mainnet, human-readable formats are practically useless, and very likely one of the first steps would be to put them in some form of database anyway. Directly adding SQLite3 dumping support on the other hand introduces an additional dependency to the non-wallet part of bitcoind and the risk of increased maintenance burden (see e.g. https://github.com/bitcoin/bitcoin/pull/24952#issuecomment-1163551060, https://github.com/bitcoin/bitcoin/issues/24628#issuecomment-1108469715).
## Proposed solution
This PR follows the "external tooling" route by adding a simple Python script for achieving the same goal in a two-step process (first create compact-serialized UTXO set via `dumptxoutset`, then convert it to SQLite via the new script). Executive summary:
- single file, no extra dependencies (sqlite3 is included in Python's standard library [1])
- ~150 LOC, mostly deserialization/decompression routines ported from the Core codebase and (probably the most difficult part) a little elliptic curve / finite field math to decompress pubkeys (essentialy solving the secp256k1 curve equation y^2 = x^3 + 7 for y given x, respecting the proper polarity as indicated by the compression tag)
- creates a database with only one table `utxos` with the following schema:
```(txid TEXT, vout INT, value INT, coinbase INT, height INT, scriptpubkey TEXT)```
- the resulting file has roughly 2x the size of the compact-serialized UTXO set (this is mostly due to encoding txids and scriptpubkeys as hex-strings rather than bytes)
[1] note that there are some rare cases of operating systems like FreeBSD though, where the sqlite3 module has to installed explicitly (see #26819)
A functional test is also added that creates UTXO set entries with various output script types (standard and also non-standard, for e.g. large scripts) and verifies that the UTXO sets of both formats match by comparing corresponding MuHashes. One MuHash is supplied by the bitcoind instance via `gettxoutsetinfo muhash`, the other is calculated in the test by reading back the created SQLite database entries and hashing them with the test framework's `MuHash3072` module.
## Manual test instructions
I'd suggest to do manual tests also by comparing MuHashes. For that, I've written a go tool some time ago which would calculate the MuHash of a sqlite database in the created format (I've tried to do a similar tool in Python, but it's painfully slow).
```
$ [run bitcoind instance with -coinstatsindex]
$ ./src/bitcoin-cli dumptxoutset ~/utxos.dat
$ ./src/bitcoin-cli gettxoutsetinfo muhash <block height returned in previous call>
(outputs MuHash calculated from node)
$ ./contrib/utxo-tools/utxo_to_sqlite.py ~/utxos.dat ~/utxos.sqlite
$ git clone https://github.com/theStack/utxo_dump_tools
$ cd utxo_dump_tools/calc_utxo_hash
$ go run calc_utxo_hash.go ~/utxos.sqlite
(outputs MuHash calculated from the SQLite UTXO set)
=> verify that both MuHashes are equal
```
For a demonstration what can be done with the resulting database, see https://github.com/bitcoin/bitcoin/pull/24952#pullrequestreview-956290477 for some example queries. Thanks go to LarryRuane who gave me to the idea of rewriting this script in Python and adding it to `contrib`.

Pull request description:
The PR changes behavior of negated `-noseednode`, `-nobind`, `-nowhitebind`, `-norpcbind`, `-norpcallowip`, `-norpcwhitelist`, `-notest`, `-noasmap`, `-norpcwallet`, `-noonlynet`, and `-noexternalip` options, so negating these options just clears previously specified values doesn't have other side effects.
Negating options on the command line can be a useful way of resetting options that may have been set earlier in the command line or config file. But before this change, negating these options wouldn't fully reset them, and would have confusing and undocumented side effects (see commit descriptions for details). Now, negating these options just resets them and behaves the same as not specifying them.
Motivation for this PR is to fix confusing behaviors and also to remove incorrect usages of the `IsArgSet()` function. Using `IsArgSet()` tends to lead to negated option bugs in general, but it especially causes bugs when used with list settings returned by `GetArgs()`, because when these settings are negated, `IsArgSet()` will return true but `GetArgs()` will return an empty list. This PR eliminates all uses of `IsArgSet()` and `GetArgs()` together, and followup PR #17783 makes it an error to use `IsArgSet()` on list settings, since calling `IsArgSet()` is never actually necessary. Most of the changes here were originally made in #17783 and then moved here to be easier to review and avoid a dependency on #16545.

fa8e0956c2 rpc: Remove deprecated dummy alias for listtransactions::label (MarcoFalke)
Pull request description:
The RPC arg is not a dummy, but a label, so offering an undocumented alias is inconsistent with all other label interfaces and confusing at best, if not entirely unused.
Fix it by removing the deprecated alias.
This pull is a breaking change, but it should be limited, because it only affects someone using the deprecated named arg on this RPC. I can't imagine anyone doing this, because in all other places where label args are accepted, they are called `label`. If someone really didn't use `label` here as named arg, it would be trivial and less confusing for them to fix it up.
