f9ce0eadf4 For feebump, ignore abandoned descendant spends (John Moffett)
Pull request description:
Closes#26667
To be eligible for fee-bumping, a transaction must not have any of its outputs (eg - change) spent in other unconfirmed transactions in the wallet. This behavior is currently [enforced](9e229a542f/src/wallet/feebumper.cpp (L25-L28)) and [tested](9e229a542f/test/functional/wallet_bumpfee.py (L270-L286)).
However, this check shouldn't apply to spends in abandoned descendant transactions, as explained by #26667.
`CWallet::IsSpent` already carves out an exception for abandoned transactions, so we can just use that.
I've also added a new test to cover this case.

Pull request description:
This PR fixes a bug and improves the mempool accept interface to return information more predictably.
Bug: In package validation, we first try the transactions individually (see doc/policy/packages.md for more explanation) and, if they all failed for missing inputs and policy-related (i.e. fee) reasons, we'll try package validation. Otherwise, we'll just "quit early" since, for example, if a transaction had an invalid signature, adding a child will not help make it valid. Currently, when we quit early, we're not setting the `package_state` to be invalid, so the caller might think it succeeded. Also, we're returning no results - it makes more sense to return the individual transaction failure. Thanks instagibbs for catching https://github.com/bitcoin/bitcoin/pull/25038#discussion_r1013293248!
Also, make the package results interface generally more useful/predictable:
- Always return the feerate at which a transaction was considered for `CheckFeeRate` in `MempoolAcceptResult::m_effective_feerate` when it was successful. This can replace the current `PackageMempoolAcceptResult::m_package_feerate`, which only sometimes exists.
- Always provide an entry for every transaction in `PackageMempoolAcceptResult::m_tx_results` when the error is `PCKG_TX`.

This value creates an extremely confusing interface as its existence is
dependent upon implementation details (whether something was submitted
on its own, etc). MempoolAcceptResult::m_effective_feerate is much more
helpful, as it always exists for submitted transactions.

21ad4e26ec test: add coverage for cross-chain wallet restore (Sebastian Falbesoner)
8c7222bda3 wallet: fix GUI crash on cross-chain legacy wallet restore (Sebastian Falbesoner)
Pull request description:
Restoring a wallet backup from another chain should result in a dedicated error message (we have _"Wallet files should not be reused across chains. Restart bitcoind with -walletcrosschain to override."_ for that). Unfortunately this is currently not the case for legacy wallet restores, as in the course of cleaning up the newly created wallet directory a `filesystem_error` exception is thrown due to the directory not being empty; the wallet database did indeed load successfully (otherwise we wouldn't know that the chain doesn't match) and hence BDB-related files and directories are already created in the wallet directory.
For bitcoind, this leads to a very confusing error message:
```
$ ./src/bitcoin-cli restorewallet test123 ~/.bitcoin/regtest/wallets/regtest_wallet/wallet.dat
error code: -1
error message: filesystem error: in remove: Directory not empty ["/home/thestack/.bitcoin/wallets/test123"]
```
Even worse, the GUI crashes in such a scenario:
```
libc++abi: terminating with uncaught exception of type std::__1::__fs::filesystem::filesystem_error: filesystem error: in remove: Directory not empty ["/home/thestack/.bitcoin/wallets/foobar"]
Abort trap (core dumped)
```
Fix this by simply deleting the whole folder via `fs::remove_all`. With this, the expected error message appears both for the `restorewallet` RPC call and in the GUI (as a message-box):
```
$ ./src/bitcoin-cli restorewallet test123 ~/.bitcoin/regtest/wallets/regtest_wallet/wallet.dat
error code: -4
error message:
Wallet loading failed. Wallet files should not be reused across chains. Restart bitcoind with -walletcrosschain to override.

Pull request description:
Work decoupled from #25806, which cleanup and improves the Coin Selection flow further.
Adding the capability to propagate specific error messages from the Coin Selection process to the user.
Instead of always returning the general "Insufficient funds" message which is not always accurate to what happened internally.
Letting us instruct the user how to proceed under certain circumstances.
The following error messages were added:
1) If the selection result exceeds the maximum transaction weight,
we now will return:
-> "The inputs size exceeds the maximum weight. Please try sending
a smaller amount or manually consolidating your wallet's UTXOs".
2) If the user pre-selected inputs and disallowed the automatic coin
selection process (no other inputs are allowed), we now will
return:
-> "The preselected coins total amount does not cover the transaction
target. Please allow other inputs to be automatically selected or include
more coins manually".
3) The double-counted preset inputs during Coin Selection error will now
throw an "internal bug detected" message instead of crashing the node.
The essence of this work comes from several comments:
1. https://github.com/bitcoin/bitcoin/pull/26560#discussion_r1037395665

b2aa9e8528 Add release note for MIN_STANDARD_TX_NONWITNESS_SIZE relaxation (Greg Sanders)
8c5b3646b5 Relax MIN_STANDARD_TX_NONWITNESS_SIZE to 65 non-witness bytes (Greg Sanders)
Pull request description:
Since the original fix was set to be a "reasonable" transaction to reduce allocations and the true motivation later revealed, it makes sense to relax this check to something more principled.
There are more exotic transaction patterns that could take advantage of a relaxed requirement, such as 1 input, 1 output OP_RETURN to burn a utxo to fees for CPFP purposes when change isn't practical.
Two changes could be accomplished:
1) Anything not 64 bytes could be allowed
2) Anything above 64 bytes could be allowed
In the Great Consensus Cleanup, suggestion (2)
was proposed as a consensus change, and is the simpler of the two suggestions. It would not allow an "empty" OP_RETURN but would reduce the required padding from 22 bytes to 5.
The functional test is also modified to test the actual case
we care about: 64 bytes

dc12f2e212 test: improve error msg on previous release tarball extraction failure (kdmukai)
7121fd8fa7 test: self-sign previous release binaries for arm64 macOS (kdmukai)
Pull request description:
## The Problem
If you run `test/get_previous_releases.py -b` on an M1 or M2 mac, you'll get an unsigned v23.0 binary in the arm64 tarball. macOS [sets stricter requirements on ARM binaries](https://news.ycombinator.com/item?id=26996578) so the unsigned arm64 binary is apparently completely unusable without being signed/notarized(?).
This means that any test that depends on a previous release (e.g. `wallet_backwards_compatibility.py`) will fail because the v23.0 node cannot launch:
```
TestFramework (ERROR): Assertion failed
Traceback (most recent call last):
File "/Users/kdmukai/dev/bitcoin-core/test/functional/test_framework/test_framework.py", line 563, in start_nodes
node.wait_for_rpc_connection()
File "/Users/kdmukai/dev/bitcoin-core/test/functional/test_framework/test_node.py", line 231, in wait_for_rpc_connection
raise FailedToStartError(self._node_msg(
test_framework.test_node.FailedToStartError: [node 2] bitcoind exited with status -9 during initialization
```
This can also be confirmed by downloading bitcoin-23.0-arm64-apple-darwin.tar.gz (https://bitcoincore.org/bin/bitcoin-core-23.0/) and trying to run any of the binaries manually on an M1 or M2 mac.
## Solution in this PR
(UPDATED) Per @ hebasto, we can self-sign the arm64 binaries. This PR checks each binary in the previous release's "bin/" and verifies if the arm64 binary is signed. If not, attempt to self-sign and confirm success.
(note: an earlier version of this PR downloaded the x86_64 binary as a workaround but this approach has been discarded)
## Longer term solution
If possible, produce signed arm64 binaries in a future v23.x tarball?
Note that this same problem affects the new v24.0.1 arm64 tarball so perhaps a signed v24.x.x tarball would also be ideal?
That being said, this PR will check all current and future arm64 binaries and self-sign as needed, so perhaps we need not worry about pre-signing the tarball binaries. And I did test a version of `get_previous_releases.py` that includes the new v24.0.1 binaries and it successfully self-signed both v23.0 and v24.0.1, as expected.
## Further info:
Somewhat related to: https://github.com/bitcoin/bitcoin/issues/15774#issuecomment-1265164753
And @ fanquake noted on IRC that you can confirm which binaries are or are not signed via:
```
$ codesign -v -d bitcoin-qt
bitcoin-qt: code object is not signed at all

31fdc54dba test: speed up wallet_fundrawtransaction.py and wallet_sendall.py (kdmukai)
Pull request description:
## Problem
`wallet_fundrawtransaction.py` and `wallet_sendall.py` are the two slowest functional tests *when running without a RAM disk*.
```
# M1 MacBook Pro timings
wallet_fundrawtransaction.py --descriptors | ✓ Passed | 55 s
wallet_fundrawtransaction.py --legacy-wallet | ✓ Passed | 381 s
wallet_sendall.py --descriptors | ✓ Passed | 43 s
wallet_sendall.py --legacy-wallet | ✓ Passed | 327 s
```
In each case, the majority of the time is spent iterating through 1500 to 1600 `getnewaddress()` calls. This is particularly slow in the `--legacy-wallet` runs.
see: https://github.com/bitcoin/bitcoin/blob/master/test/functional/wallet_fundrawtransaction.py#L986-L987
see: https://github.com/bitcoin/bitcoin/blob/master/test/functional/wallet_sendall.py#L324
## Solution
Pre-fill the keypool before iterating through those `getnewaddress()` calls.
With this change, the execution time drops to:
```
wallet_fundrawtransaction.py --descriptors | ✓ Passed | 52 s # -3s diff
wallet_fundrawtransaction.py --legacy-wallet | ✓ Passed | 291 s # -90s diff
wallet_sendall.py --descriptors | ✓ Passed | 27 s # -16s diff
wallet_sendall.py --legacy-wallet | ✓ Passed | 228 s # -99s diff
```

Pull request description:
When configured with `--enable-debug`, many tests become dramatically slower. These slow downs are particularly noticed in tests that generate a lot of blocks in separate calls, make a lot of RPC calls, or send a lot of data from the test framework's P2P connection. This PR aims to improve the runtime of some of the slower tests and improve the overall runtime of the test runner. This has improved the runtime of the test runner from ~400s to ~140s on my computer.
The slowest test by far was `wallet_import_rescan.py`. This was taking ~320s. Most of that time was spent waiting for blocks to be mined and then synced to the other nodes. It was generating a new block for every new transaction it was creating in a setup loop. However it is not necessary to have one tx per block. By mining a block only every 10 txs, the runtime is improved to ~61s.
The second slowest test was `feature_fee_estimation.py`. This test spends most of its time waiting for RPCs to respond. I was able to improve its runtime by batching RPC requests. This has improved the runtime from ~201s to ~140s.
In `feature_taproot.py`, the test was constructing a Python `CScript` using a very large list of `OP_CHECKSIG`s. The constructor for the Python implementation of `CScript` was iterating this list in order to create a `bytes` from it even though a `bytes` could be created from it without iterating. By making the `bytes` before passing it into the constructor, we are able to improve this test's runtime from ~131s to ~106s.
Although `interface_rpc.py` was not typically a slow test, I found that it would occasionally have a super long runtime. It typically takes ~7s, but I have observed it taking >400s to run on occasion. This longer runtime occurs more often when `--enable-debug`. This long runtime was caused by the "exceeding work queue" test which is really just trying to trigger a race condition. In this test, it would create a few threads and try an RPC in a loop in the hopes that eventually one of the RPCs would be added to the work queue while another was processing. It used `getrpcinfo` for this, but this function is fairly fast. I believe what was happening was that with `--enable-debug`, all of the code for receiving the RPC would often take longer to run than the RPC itself, so the majority of the requests would succeed, until we got lucky after 10's of thousands of requests. By changing this to use a slow RPC, the race condition can be triggered more reliably, and much sooner as well. I've used `waitfornewblock` with a 500ms timeout. This improves the runtime to ~3s consistently.
The last test I've changed was `rpc_packages.py`. This test was one of the higher runtime variability tests. The main source of this variation appears to be waiting for the test node to relay a transaction to the test framework's P2P connection. By whitelisting that peer, the variability is reduced to nearly 0.
Lastly, I've reordered the tests in `test_runner.py` to account for the slower runtimes when configured with `--enable-debug`. Some of the slow tests I've looked at were listed as being fast which was causing overall `test_runner.py` runtime to be extended. This change makes the test runner's runtime be bounded by the slowest test (currently `feature_fee_estimation.py` with my usual config (`-j 60`).
