c6119f478876f245ca5c65dd05da4cdc5be0e91f tests: Use unique port for ZMQ tests (Andrew Chow)
Pull request description:
The ZMQ interface tests should use unique ports as we do for the p2p and rpc ports so that multiple instances of the test can be run at the same time.
Without this, the test may hang until killed, or fail.

watchonly/solvable wallets
730e14a317ae45fe871c8d6f44a51936756bbbea test: wallet: check that labels are migrated to watchonly wallet (Sebastian Falbesoner)
d5f4ae7fac0bceb0c9ad939b9a4fbdb85da0bf95 wallet: fully migrate address book entries for watchonly/solvable wallets (Sebastian Falbesoner)
Pull request description:
Currently `migratewallet` migrates the address book (i.e. labels and purposes) for watchonly and solvable wallets only in RAM, but doesn't persist them on disk. Fix this by adding another loop for both of the special wallet types after which writes the corresponding NAME and PURPOSE entries to the database in a single batch. Also adds a corresponding test that checks if labels were migrated correctly for a watchonly wallet.

e6864fa157d75d8ae2b2f56620b019bde2355a24 contrib: remove builder keys (fanquake)
Pull request description:
This has been superseded by adding a builder-keys/ directory in
guix.sigs, where the presence of keys, and validity of signatures
is checked. Preventing issues like missing keys or invalid signatures.

they open adding attestations.

cross-chain legacy wallet restore
21ad4e26ec320dcecc8961888bc82d0bb72d5ed3 test: add coverage for cross-chain wallet restore (Sebastian Falbesoner)
8c7222bda3f7136f312a6e57b76d6a2d0a114f68 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.

subprocesses as for `all-lint.py`
f6eadaa413f20c1853cf1bea5141560cd5e4b15a Use same Python executable for subprocesses as for all-lint.py (Kristaps Kaupe)
Pull request description:
Before this all linters were ran by `/usr/bin/env python3`, no matter what was used to run `test/lint/all-lint.py`. This change allows to use non-default Python executable for `test/lint/all-lint.py` and then all subprocesses will also use same Python interpreter (for example, `python3.10 ./test/lint/all-lint.py`). See https://github.com/bitcoin/bitcoin/issues/26792#issuecomment-1369558866 as use case.

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

04609284ad5e0b72651f2d4b43263461ada40816 rpc: Improve error when wallet is already loaded (Aurèle Oulès)
Pull request description:
Currently, trying to load a descriptor (sqlite) wallet that is already loaded throws the following error:

I don't think it is very clear what it means for a user.
While a legacy wallet would throw:
> error code: -35
> error message:
> Wallet file verification failed. Refusing to load database. Data file '/home/user/.bitcoin/signet/wallets/test_wallet/wallet.dat' is already loaded.
This PR changes the error message for both types of wallet to:

to 65 non-witness bytes

8c5b3646b5afe8a61f5c66478d8e11f0d2ce5108 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

can't run unsigned arm64 binaries; self-sign when needed
dc12f2e212dfacbe238cf68eb454b9ec71169bbc test: improve error msg on previous release tarball extraction failure (kdmukai)
7121fd8fa7de50ff67157f81f9e0f267b9795dbb 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
```

31fdc54dba92fe9d7d8289f1e4380082838a74a9 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:
Fixes #26719
"Crypted" is used in some comments at `walletload_tests` because it refers to `DBKeys::CRYPTED_KEY`, it's not necessary
a mistake.
Obs: I can change the approach (changing `walletload_tests` comments to use `encrypted` word instead of adding it to the `ignore_words`) if reviewers think it makes more sense.

This has been superseded by adding a builder-keys/ directory in
guix.sigs, where the presence of keys, and validity of signatures
is checked. Preventing issues like missing keys or invalid signatures.
New (or exisiting) Guix builders can add their key in the next PR
they open adding attestations.

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 the route taken.
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

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`).

Pull request description:
Reopens #16037
I have rebased the PR, addressed the comments of the original PR and added a functional test.
> Before this change importwallet fails if any block is pruned. This PR makes it possible to importwallet if all required blocks aren't pruned. This is possible because the dump format includes key timestamps.
For reviewers:
`python test/functional/wallet_pruning.py --nocleanup` will generate a large blockchain (~700MB) that can be used to manually test wallet imports on a pruned node. Node0 is not pruned, while node1 is.
