fa673cf344 lint: Call lint_scripted_diff from test_runner (MarcoFalke)
Pull request description:
The lint `commit-script-check.sh` can not be called from the test_runner at all and must be called manually. Also, some checks require `COMMIT_RANGE` to be set.
Fix all issues by moving two lint checks into the test_runner. Also, the proper commit range is passed to the checks by the test_runner, so that the user no longer has to do it.

42d5d53363 interfaces: Add helper function for wallet on pruning (Fabian Jahr)
Pull request description:
A test that is added as part of #30455 uncovered this issue: The `GuessVerificationProgress` function is used during during descriptor import and relies on `m_chain_tx_count`. In #29370 an [`Assume` was added](0fd915ee6b) expecting the `m_chaint_tx_count` to be set. However, as the test uncovered, `GuessVerificationProgress` is called with background sync blocks that have `m_chaint_tx_count = 0` when they have not been downloaded and processed yet.
The simple fix is to remove the `Assume`. Users should not be thrown off by the `Internal bug detected` error. The behavior of `importdescriptor` is kept consistent with the behavior for blocks missing due to pruning.
The test by alfonsoromanz is cherry-picked here to show that the [CI errors](https://cirrus-ci.com/task/5110045812195328?logs=ci#L2535) should be fixed by this change.
This PR also improves error messages returned by the `importdescriptors` and `rescanblockchain` RPCs. The error message now changes depending on the situation of the node, i.e. if pruning is happening or an assumutxo backgroundsync is active.

Pull request description:
Added a test for the Negative timeout error if the rpc is given a negative value for its timeout arg
This adds coverage to the `waitfornewblock` rpc
you can check to see there is no coverage for this error by doing
`grep -nri "Negative timeout" ./test/`
and nothing shows up, you can also see by manually checking where we call `waitfornewblock` in the functional tests

0713548137 refactor: add GetMinimumTime() helper (Sjors Provoost)
Pull request description:
#30681 fixed the `curtime` field of `getblocktemplate` to take the timewarp rule into account. However I forgot to do the same for the `mintime` field, which was hardcoded to use `pindexPrev->GetMedianTimePast()+1`.
This PR adds a helper `GetMinimumTime()` and uses it for the `mintime` field.
#31376 changed the `curtime` field to always account for the timewarp rule. This PR maintains that behavior.
Note that `mintime` now always applies BIP94, including on mainnet. This makes future softfork activation safer.
It could be backported to v28.

152a2dcdef test: fix intermittent timeout in p2p_1p1c_network.py (Martin Zumsande)
Pull request description:
The timeout is due to outstanding txrequests with python peers, which have the same timeout (`60s`) as the mempool sync timeout.
I explained this in more detail in https://github.com/bitcoin/bitcoin/issues/31721#issuecomment-2620169640 and also mentioned there how to reproduce it.
Fix this by disconnecting the python peers after they send their txns, they aren't needed after this point anyway because the main goal of the test is the sync between the 4 full nodes.

d45eb3964f test: compare BDB dumps of test framework parser and wallet tool (Sebastian Falbesoner)
01ddd9f646 test: complete BDB parser (handle internal/overflow pages, support all page sizes) (Sebastian Falbesoner)
Pull request description:
This PR adds missing features to our test framework's BDB parser with the goal of hopefully being able to read all legacy wallets that are created with current and past versions of Bitcoin Core. This could be useful both for making review of https://github.com/bitcoin/bitcoin/pull/26606 easier and to also possibly improve our functional tests for the wallet BDB-ro parser by additionally validating it with an alternative implementation. The second commits introduces a test that create a legacy wallet with huge label strings (in order to create overflow pages, i.e. pages needed for key/value data than is larger than the page size) and compares the dump outputs of wallet tool and the extended test framework BDB parser.
It can be exercised via `$ ./test/functional/tool_wallet.py --legacy`. BDB support has to be compiled in (obviously).
For some manual tests regarding different page sizes, the following patch can be used:
```diff
diff --git a/src/wallet/bdb.cpp b/src/wallet/bdb.cpp
index 38cca32f80..1bf39323d3 100644

if (ret != 0) {
throw std::runtime_error(strprintf("BerkeleyDatabase: Error %d, can't open database %s", ret, strFile));
```
I verified that the newly introduced test passes with all valid page sizes between 512 and 65536.

p2p_orphan_handling checks whether a message has not been requested slightly
too soon, making the check always succeed. This passes unnoticed since the
expected result is for the message to not have been received, but it will make
the test not catch a relevant change that should make it fail
p2p_ibd_txrelay expects no GETDATA to have been received by a peer after
announcing a transaction. The reason is that the node is doing IBD, so
transaction requests are not replied to. However, the way this is checked
is wrong, and the check will pass even if the node **was not** in IBD.
This is due to the mocktime not being properly initialized, so the check
is always performed earlier than it should, making it impossible for the
request to be there
The timeout is due to outstanding txrequests with
python peers. Fix this by disconnecting these peers
after they send their txns, they aren't needed after
this point anyway.
Previously in getblocktemplate only curtime took the timewarp rule into account.
Mining pool software could use either, though in general it should use curtime.

fa0dc09b90 test: Remove --noshutdown flag (MarcoFalke)
fad441fba0 test: Treat leftover process as error (MarcoFalke)
Pull request description:
The `--noshutdown` flag is brittle, confusing, and redundant:
* Someone wanting to inspect the state after a test failure will likely also want to debug the state on the python side, so the option is redundant with `--pdbonfailure`. If there was a use case to replicate `--pdbonfailure` without starting pdb, a dedicated flag could be added for that use case.
* It is brittle to use the flag for a passing test, because it will disable checks in the test. For example, on shutdown LSan will perform a leak check, and the test framework will check that the node did not crash, and it will check that the node did not print errors to stderr.
Fix all issues by removing it.
Also, tidy up startup error messages to be less confusing as a result.

- Rename `invalid_call` parameter to `called_by_framework` in `generateblock`, `generatetoaddress` and `generatetodescriptor` mining methods to better express its intended usage.
- Add explicit assertion message clarifying that these functions should only be called by TestFramework itself to maintain proper node synchronization.

Pull request description:
This is a simple test PR that does two things:
1. Raise an exception in `_bulk_tx_` when `target_vsize` is too low, i.e., below the tx vsize.
2. Addresses some review comments from https://github.com/bitcoin/bitcoin/pull/30162, which are:
- Raise an error if the output value is less than or equal to zero in `create_self_transfer`.
This prevents creating transactions with a value of 0 or less.
- Add a test to verify that `create_self_transfer_multi` also respects the passed `target_vsize`.

Pull request description:
This probably should've been included in #12653 when `-blocksdir` was introduced. Credit TheCharlatan for noticing that it's missing.
This guards against 2 processes running with separate datadirs but the same blocksdir. I didn't add `walletdir` as I assume sqlite has us covered there.
It's not likely to happen currently, but may be more relevant in the future with applications using the kernel. Note that the kernel does not currently do any dir locking, but it should.

e0b3336822 test: p2p: fix sending of manual INVs in tx download test (Sebastian Falbesoner)
Pull request description:
The `test_inv_block` sub-test in p2p_tx_download.py has a subtle bug: the manual msg_inv announcements from peers currently have no effect, since they don't match the wtxidrelay setting (=true by default for `P2PInterface` instances) and are hence ignored by the nodes (since 2d282e0c / PR #18044):
e7c4794955/src/net_processing.cpp (L3904-L3911)
Though the test still passes on master, it does so without the intended scenario of asking an additional peer (triggering the GETDATA_TX_INTERVAL delay). Fix this by sending the INV message with MSG_WTX instead of MSG_TX. This increases the test run time by about one minute intentionally.
It might be good to avoid issues like this in the future, happy to add test framework improvements if someone has a concrete idea.

Trying to shut down a node after a test failure may fail and lead to an
RPC error.
Also, it is confusing to sidestep the existing fallback to kill any
leftover nodes on a test failure.
So just rely on the fallback.

Allowing to call the check from the test_runner allows for consistent
error messages and better UX by having a single test_runner for all
checks.
This requires the env var to be set for now. The next commit makes the
commit range optional.
This is similar in structure to test/functional/wallet_multisig_descriptor_psbt.py
both in code and concept. It should serve as some integration testing for
Miniscript descriptors, and also documents a simple multisig that starts as 4-of-4
and decays to 3-of-4, 2-of-4, and finally 1-of-4 at block heights (I think in the
real world aligning this to halvenings would be nice).
For blocks 1 through 15 the script_BIP34_coinbase_height appends OP_1
to comply with BIP34 and avoid bad-cb-length.
This is inconsistent with BlockAssembler::CreateNewBlock() which adds
OP_0 instead.
The utxo_total_supply fuzzer and MinerTestingSetup::Block also use OP_0.
Changing it is required to import the test vectors in the next commit.
It also ensures the test vectors can be regenerated using the CPU miner
at https://github.com/pooler/cpuminer without patches (it uses OP_0).
The same helper is used by the signet miner, so this will impact newly
bootstrapped signets.

Pull request description:
Part of #27463.
(Transaction) **orphan resolution** is a process that kicks off when we are missing UTXOs to validate an unconfirmed transaction. We currently request missing parents by txid; BIP 331 also defines a way to [explicitly request ancestors](https://github.com/bitcoin/bips/blob/master/bip-0331.mediawiki#handle-orphans-better).
Currently, when we find that a transaction is an orphan, we only try to resolve it with the peer who provided the `tx`. If this doesn't work out (e.g. they send a `notfound` or don't respond), we do not try again. We actually can't, because we've already forgotten who else could resolve this orphan (i.e. all the other peers who announced the transaction).
What is wrong with this? It makes transaction download less reliable, particularly for 1p1c packages which must go through orphan resolution in order to be downloaded.
Can we fix this with BIP 331 / is this "duct tape" before the real solution?
BIP 331 (receiver-initiated ancestor package relay) is also based on the idea that there is an orphan that needs resolution, but it's just a new way of communicating information. It's not inherently more honest; you can request ancestor package information and get a `notfound`. So ancestor package relay still requires some kind of procedure for retrying when an orphan resolution attempt fails. See the #27742 implementation which builds on this orphan resolution tracker to keep track of what packages to download (it just isn't rebased on this exact branch). The difference when using BIP 331 is that we request `ancpkginfo` and then `pkgtxns` instead of the parent txids.
Zooming out, we'd like orphan handling to be:
- Bandwidth-efficient: don't have too many requests out at once. As already implemented today, transaction requests for orphan parents and regular download both go through the `TxRequestTracker` so that we don't have duplicate requests out.
- Not vulnerable to censorship: don't give up too easily, use all candidate peers. See e.g. https://bitcoincore.org/en/2024/07/03/disclose_already_asked_for/
- Load-balance between peers: don't overload peers; use all peers available. This is also useful for when we introduce per-peer orphan protection, since each peer will have limited slots.
The approach taken in this PR is to think of each peer who announces an orphan as a potential "orphan resolution candidate." These candidates include:
- the peer who sent us the orphan tx
- any peers who announced the orphan prior to us downloading it
- any peers who subsequently announce the orphan after we have started trying to resolve it
For each orphan resolution candidate, we treat them as having "announced" all of the missing parents to us at the time of receipt of this orphan transaction (or at the time they announced the tx if they do so after we've already started tracking it as an orphan). We add the missing parents as entries to `m_txrequest`, incorporating the logic of typical txrequest processing, which means we prefer outbounds, try not to have duplicate requests in flight, don't overload peers, etc.

Pull request description:
All translatable format strings are fixed. This change surfaces errors in them at compile-time.
The implementation achieves this by allowing to delay the translation (or `std::string` construction) that previously happened in `_()` by returning a new type from this function. The new type can be converted to `bilingual_str` where needed.
This can be tested by adding a format string error in an original string literal and observing a new compile-time failure.

The linter has many implementation bugs and missing features.
Also, it is completely redundant with FormatStringCheck, which
constructs from ConstevalFormatString or a runtime format string.
The `test_inv_block` sub-test in p2p_tx_download.py has a subtle bug:
the manual msg_inv announcements from peers currently have no effect,
since they don't match the wtxidrelay setting (=true by default for
`P2PInterface` instances) and are hence ignored by the nodes (since
2d282e0c / PR #18044). Though the test still passes, it does so without
the intended scenario of asking an additional peer (triggering the
GETDATA_TX_INTERVAL delay). Fix this by sending the INV message with
MSG_WTX instead of MSG_TX. This increases the test run time by about one
minute.
`p2p_dns_seeds.py` would try to connect to the DNS server configured on
the machine and resolve `dummySeed.invalid`.
To block that configure an unavailable proxy which will be used also to
connect to the name server. The test needs 2 successful connections to
other peers (two Python `P2PInterface`s) and they work in spite of the
unavailable proxy because they are on `127.0.0.1` (`NET_UNROUTABLE`) and
the proxy is not used for that.
`feature_config_args.py` uses a proxy address of `1.2.3.4`. This results
in actually trying to open TCP connections over the internet to
`1.2.3.4:9050`.
The test does not need those to succeed so use `127.0.0.1:1` instead.
Also avoid `-noconnect=0` because that is interpreted as `-connect=1`
which is interpreted as `-connect=0.0.0.1` and a connection to
`0.0.0.1:18444` is attempted.
`p2p_seednode.py` would try to connect to `0.0.0.1` and `0.0.0.2` as
seed nodes. This sends outbound TCP packets on a non-loopback interface
to the default router.
Configure an unavailable proxy for all executions of `bitcoind` during
this test. Also change `0.0.0.1` and `0.0.0.2` because connecting to
them would skip the `-proxy=` setting because for such an address:
* `CNetAddr::IsLocal()` is true, thus
* `CNetAddr::IsRoutable()` is false, thus
* `CNetAddr::GetNetwork()` is `NET_UNROUTABLE`, even though
`CNetAddr::m_net` is `NET_IPV4`.
This speeds up the execution time of `p2p_seednode.py`
from 12.5s to 2.5s.

813a16a463 wallet: Add HasCryptedKeys (Andrew Chow)
Pull request description:
An earlier version allowed users to create watchonly wallets (wallets without private keys) that were "encrypted". Such wallets would have a stored encryption keys, but nothing would actually be encrypted with them. This can cause unexpected behavior such as https://github.com/bitcoin-core/gui/issues/772.
We can detect such wallets as they will have the disable private keys flag set, no encrypted keys, and encryption keys. For such wallets, we can remove those encryption keys thereby avoiding any issues that may result from this unexpected situation.

implies that no legacy wallet can be loaded into memory due to the lack of db
writing functionality.

Trying to immediately shut down a node after a startup failure without
waiting for the RPC to be fully up will in most cases just fail and lead
to an RPC error.
Also, it is confusing to sidestep the existing fallback to kill any
leftover nodes on a test failure.
So just rely on the fallback.
Printing to stderr instead of stdout makes the test_runner.py fail on
leftover processes. This is desired and fine, because a leftover process
should only happen on a test failure anyway.
`get_socket_inodes()` calls `os.listdir()` and then iterates on the
results using `os.readlink()`. However a file may disappear from the
directory after `os.listdir()` and before `os.readlink()` resulting in a
`FileNotFoundError` exception.
It is expected that this may happen for `bitcoind` which is running and
could open or close files or sockets at any time. Thus ignore the
`FileNotFoundError` exception.
If the `releases` directory exists, but still only a subset of the
necessary previous release binaries are available, the test fails by
throwing an exception (sometimes leading to follow-up exceptions like
"AssertionError: [node 0] Error: no RPC connection") and printing out
a stack trace, which can be confusing and at a first glance suggests
that the node crashed or some alike.
Improve this by checking and printing out *all* of the missing release
binaries and failing with an explicit error in this case. Also add an
info on how to download previous releases binaries.
Noticed while testing #30328.
Can be tested by e.g.
$ ./test/get_previous_releases.py -b
$ rm -rf ./releases/v28.0/
$ ./build/test/functional/wallet_migration.py
Now that we track all announcers of an orphan, it's not helpful to
consider an orphan provided by a peer that didn't send us this parent.
It can only hurt our chances of finding the right orphan when there are
multiple candidates.
Adapt the 2 tests in p2p_opportunistic_1p1c.py that looked at 1p1c
packages from different peers. Instead of checking that the right peer
is punished, we now check that the package is not submitted. We can't
use the functional test to see that the package was not considered
because the behavior is indistinguishable (except for the logs).

bc43ecaf6d test: add functional test for balance after snapshot completion (Martin Zumsande)
226d03dd61 validation: Send correct notification during snapshot completion (Martin Zumsande)
Pull request description:
After AssumeUtxo background sync is completed in a `ActivateBestChain()` call, the `GetRole()` function called with `BlockConnected()` returns `ChainstateRole::NORMAL` instead of `ChainstateRole::BACKGROUND` for this chainstate.
This would make the wallet (which ignores `BlockConnected` notifications for the background chainstate) process it, change `m_last_block_processed_height` to the (ancient) snapshot height, and display an incorrect balance.
Fix this by caching the chainstate role before calling `ActivateBestChainStep()`.
Also contains a test for this situation that fails on master.

fa0998f0a0 test: Avoid intermittent error in assert_equal(pruneheight_new, 248) (MarcoFalke)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/31446
The test uses the P2P network to sync blocks, which has no inherent guarantee that the blocks are sent and received in the right order, assuming the headers are received first.
This can mean that the first block file is flushed with block at height 249 and block at height 248 is added to the second file. In the log it looks like: `Leaving block file 0: CBlockFileInfo(blocks=249, size=65319, heights=0...249, time=2011-02-02...2024-12-03) (onto 1) (height 248)`. The test assumes that the height of the last pruned block in the first file is 248, expecting it to look like: `Leaving block file 0: CBlockFileInfo(blocks=249, size=65319, heights=0...248, time=2011-02-02...2024-12-09) (onto 1) (height 249) `.
Fix the issue by using a linear dumb sync.

ecaa786cc1 rpc: add signet_challenge field to getblockchaininfo and getmininginfo (Ash Manning)
Pull request description:
Signet challenges are currently only available via `getblocktemplate` RPC.
`getblockchaininfo` and `getmininginfo` both provide inadequate information to distinguish signets. Since these are the RPCs used to determine the current network, they should also provide the signet challenge for signets.
Test coverage is included in `test/functional/feature_signet.py`.

ad224429f8 net: additional disconnection logging (Sjors Provoost)
Pull request description:
While debugging unexpected disconnections, possibly related to #28331, I found some additional [net] logging to be useful.
All cases where we disconnect now come with a log message that has the word `disconnecting`:
* all calls to `CloseSocketDisconnect()` log `disconnecting peer=…`
* wherever we set `pnode->fDisconnect = true;`
* for all `InactivityCheck` cases (which in turn sets `fDisconnect`)
* replaces "dropping" with "disconnecting" in `Network not active, dropping peer=…`
A few exceptions are listed here: https://github.com/bitcoin/bitcoin/pull/28521#discussion_r1890824361
I changed `CloseSocketDisconnect()` to no longer log `disconnecting`, and instead have all the call sites do so.
This PR introduces two helper functions on `CNode`: `DisconnectMsg` and `LogIP`. The second and third commit use these helpers in `net_processing.cpp` so these disconnect messages are more consistent now (e.g. some didn't log the IP). No new messages are added there though.
The `LogIP()` helper is rarely used outside of a disconnect event, but it's available for future use.
Any `LogPrint` this PR touches is replaced with `LogDebug` (superseded by #30750), and every `LogPrintf ` with `LogInfo`.

This is harmless, but confusing.
Fix it by collecting statistics only when the program has not aborted. (Can be reviewed with `--color-moved=dimmed-zebra`)

0e2b12b92a net, init: derive default onion port if a user specified a -port (Martin Zumsande)
Pull request description:
This resolves#31133 (setups with multiple local nodes each using a different `-port` no longer working with v28.0, see the issue description for more details) by deriving the default onion listening port to be the value specified by `-port` incremented by 1 (idea by vasild / laanwj).
Note that with this fix, the chosen `-port` values of two local nodes cannot be adjacent, otherwise there will be port collisions again.
From the discussion in the linked issue, this was the most popular option, followed by doing nothing and telling affected users to change their setups to use `-bind` instead of `-port`. But more opinions are certainly welcome!
I think that if we decide to do something about the problem described in the issue, we should do so soon (in 28.1.), so I opened this PR.

62b2d23edb wallet: Migrate non-HD keys to combo() descriptor (Ava Chow)
Pull request description:
Non-HD keys do not have an HD seed ID associated with them, so if this value is the null value (all 0s), then we should not perform any seed ID comparison that would result in excluding the keys from combo() migration.
This changes the migration of non-HD wallets (or blank wallets with imported private keys) to make a single combo() descriptors for the non-HD/imported keys, rather than pk(), pkh(), sh(wpkh()), and wpkh() descriptors for the keys.

On failure, this makes the output more consistent with the other linter.
Each failure will be marked with an '⚠️ ' emoji and explanation, making
it easier to spot.
Also, add --line-number to the filesystem linter.
Also, add newlines after each failing check, to visually separate
different failures from each other.
Can be reviewed with:

During migration failure, only load wallet back into memory when the
wallet was loaded prior to migration. This fixes the case where BDB
is not supported, which implies that no legacy wallet can be loaded
into memory due to the lack of db writing functionality.
This commit also improves migration backup related comments to better
document the current workflow.

988721d37a test: avoid internet traffic in rpc_net.py (Sebastian Falbesoner)

Can be tested by running
```

ec777917d6 test: Fix intermittent issue in wallet_backwards_compatibility.py (Randall Naar)
Pull request description:
When creating and replacing a transaction using `bumpfee`, an async update is sent in the form of the `TransactionAddedToMempool` and `TransactionRemovedFromMempool` signals. When `wallet_backwards_compatibility.py` creates `tx3_id` this way and replaces it with `tx4_id`, the `abandontransaction` rpc is called right after. In some cases the `TransactionAddedToMempool` and `TransactionRemovedFromMempool` is handled after the transaction is abandoned in the wallet, and overwrites the transaction's `abandoned` flag. This PR forces the signals to get handled before `abandontransaction` is called by invoking `self.sync_mempools` which calls `syncwithvalidationinterfacequeue` on every node's rpc connection.
This will mitigate the immediate inconsistency observed with the abandontransaction call, but the potential race conditions between the signals and wallet operations may also be useful to note in a separate issue (if it's okay to not address it in this one).

Non-HD keys in legacy wallets without a HD seed ID were being migrated
to separate pk(), pkh(), sh(wpkh()), and wpkh() descriptors for each key.
These could be more compactly represented as combo() descriptors, so
migration should make combo() for them.
It is possible that existing non-HD wallets that were migrated, or
wallets that started blank and had private keys imported into them have
run into this issue. However, as the 4 descriptors produce the same output
scripts as the single combo(), so any previously migrated wallets are
not missing any output scripts. The only observable difference should be
performance related, and the wallet size on disk.

932cd1e92b wallet: fix crash during watch-only wallet migration (furszy)
Pull request description:
The crash occurs because we assume the cached scripts structure will not be empty,
but it can be empty for watch-only wallets that start blank.
This also adds test coverage for standalone imported keys, which were also crashing
because pubkey imports are treated the same way as hex script imports through
`importaddress()`.
Testing Notes:
This can be verified by cherry-picking and running any of the test commits on master.
It will crash there but pass on this branch.

7239ddb7ce test: make sure node has all transactions (brunoerg)
ee1b9bef00 test: replace `is not` to `!=` when comparing block hash (brunoerg)
Pull request description:
`test_invalid_tx_in_compactblock` tests that we don't get disconnected if we relay a compact block with valid header, but invalid transactions.
In this test, after sending the block with invalid transactions, this test checks two things: the tip in the receiver node did not advance and the sender did not get disconnected. However, even if the block contains only valid transactions, the tip would not advance because the receiver does not have all transactions to reconstruct the valid and would request them back. This PR fixes it by sending all the transactions.
Also, comparing block hash (int) using `is not` can lead to subtle bugs, this PR fixes it by replacing it to `!=`.

Pull request description:
The changes are required for https://github.com/bitcoin/bitcoin/pull/31061, however they also make sense on their own. For example, they are fixing up an `inline namespace`, which lead to compile errors otherwise (can be tested by observing the compile error after reverting the changes to `src/util/strencodings.h`). Also, a unit test comment is fixed.

faf70cc994 Remove wallet::ParseISO8601DateTime, use ParseISO8601DateTime instead (MarcoFalke)
2222aecd5f util: Implement ParseISO8601DateTime based on C++20 (MarcoFalke)
Pull request description:
`boost::posix_time` in `ParseISO8601DateTime` has many issues:
* It parses random strings that are clearly invalid and returns a time value for them, see [1] below.
* None of the separators `-`, or `:`, or `T`, or `Z` are validated.
* It may crash when running under a hardened C++ library, see https://github.com/bitcoin/bitcoin/issues/28917.
* It has been unmaintained for years, so reporting or fixing any issues will most likely be useless.
* It pulls in a third-party dependency, when the functionality is already included in vanilla C++20.
Fix all issues by replacing it with a simple helper function written in C++20.
Fixes https://github.com/bitcoin/bitcoin/issues/28917.

Pull request description:
With the introduction of a mining ipc interface and the potential future introduction of a kernel library API it becomes increasingly important to offer common behaviour between them. An example of this is ProcessNewBlock, which is used by ipc, rpc, net_processing and (potentially) the kernel library. Having divergent behaviour on suggested pre-checks and checks for these functions is confusing to both developers and users and is a maintenance burden.
The rpc interface for ProcessNewBlock (submitblock) currently pre-checks if the block has a coinbase transaction and whether it has been processed before. While the current example binary for how to use the kernel library, bitcoin-chainstate, imitates these checks, the other interfaces do not.
The coinbase check is repeated again early during ProcessNewBlock. Pre-checking it may also shadow more fundamental problems with a block. In most cases the block header is checked first, before validating the transactions. Checking the coinbase first therefore masks potential issues with the header. Fix this by removing the pre-check.
Similary the duplicate checks are repeated early in the contextual checks of ProcessNewBlock. If duplicate blocks are detected much of their validation is skipped. Depending on the constitution of the block, validating the merkle root of the block is part of the more intensive workload when validating a block. This could be an argument for moving the pre-checks into block processing. In net_processing this would have a smaller effect however, since the block mutation check, which also validates the merkle root, is done before.
Testing spamming a node with valid, but duplicate unrequested blocks seems to exhaust a CPU thread, but does not seem to significantly impact keeping up with the tip. The benefits of adding these checks to net_processing are questionable, especially since there are other ways to trigger the more CPU-intensive checks without submitting a duplicate block. Since these DOS concerns apply even less to the RPC interface, which does not have banning mechanics built in, remove them too.
Finally, also remove the pre-checks from `bitcoin-chainstate.cpp`.

This ensures we don't needlessly start the node, and reduces implicit dependencies between test functions.
test_seed_peers() - Move assert calling RPC to verify correct chain after our own function actually started the node.
This makes the debug output mostly the same for -par=1 and parallel validation runs. Of course,
parallel validation is non-deterministic in what error it may encounter first if there are
multiple issues. Also, the way certain script-related and non-script-related checks are
performed differs between the two modes still, which may result in discrepancies.
409d0d6293 test: enable running individual independent functional test methods (ismaelsadeeq)
Pull request description:
- Some test methods in the functional test framework are independent and do not require any prior context or setup in `run_test`.
- This commit adds a new option for running these specific methods within a test file, allowing them to be executed individually without running the entire test suite.
- Using this option reduces the time you need to wait before the test you are interested in starts executing.
- The functionality added by this PR can be achieved manually by commenting out code, but having a pragmatic option to do this is more convenient.
Note: Running test methods that require arguments or context will fail.
**Example Usage**:
```zsh
build/test/functional/feature_reindex.py --test_methods continue_reindex_after_shutdown
```
```zsh
build/test/functional/feature_config_args.py --test_methods test_log_buffer test_args_log test_connect_with_seednode

Code review ACK 409d0d6293. This seems like a good step towards making it easy to run independent tests quickly. I think ideally there would be some naming convention or @ annotation added to test methods that can run independently, so the test framework could provide more functionality like being able to list test methods, being able to show command lines to quickly reproduce problems when tests fails, and calling test methods automatically instead of requiring individual tests to call them. But these ideas are all compatible with the new `--test_methods` option

62f6d9e1a4 test: simple ordering optimization to reduce runtime (tdb3)
Pull request description:
Noticed in #31371 that the position of `mempool_ephemeral_dust` within `BASE_SCRIPTS` was lengthening total test runtime. Instead of moving only that test, looked for others to move to reduce runtime.
This is a quick optimization that was found to reduce overall functional test runtime of up to around 20% (depending on jobs and machine characteristics). Since it seems like test ordering could be done in many different ways, with many variables, and bike shedding could creep in, a relatively straightforward approach was taken for now that minimized changes to test_runner.

Pull request description:
The RPC command `scanblocks` provides a useful way to get a set of blockhashes that have activity relevant to a set of descriptors (`relevant_blocks`). However actually extracting the activity from those blocks is left as an exercise to the end user.
This process involves not only generating the (potentially ranged) set of scripts for the descriptor set on the client side (maybe via `deriveaddresses`), but then the user must retrieve each block's contents one-by-one using `getblock <hash>`, which is transmitted over a network link. And that's all before they perform the actual search over block content. There's even more work required to incorporate unconfirmed transactions.
This PR introduces an RPC `getdescriptoractivity` that [dovetails](https://bitcoin-irc.chaincode.com/bitcoin-core-dev/2024-08-16#1046393;) with `scanblocks` output, handling the process described above. Users specify the blockhashes (perhaps from `relevant_blocks`) and a set of descriptors; they are then given all spend/receive activity in that set of blocks.
This is a very useful tool when implementing lightweight wallets that want neither to require a third-party indexer like electrs, nor the overhead of creating and managing watch-only wallets in Core. This allows Core to be more easily used in a "stateless" manner by wallets, with potentially many nodes interchangeably acting as backends.

This is not a pure refactor:
1. It slightly changes the log messages, as reflected in the test changes
2. It adds the IP address to all disconnect logging (when fLogIPs is set)
And under the hood suppoert single transactions
in AcceptPackage. This simplifies user experience
and paves the way for reducing number of codepaths
for transaction acceptance in the future.

This tests the new submitblock behaviour that is introduced in the
previous commit: Submitting a previously pruned block should persist the
block's data again.
The coinbase check is repeated again early during ProcessNewBlock.
Pre-checking it may also shadow more fundamental problems with a block.
In most cases the block header is checked first, before validating the
transactions. Checking the coinbase first therefore masks potential
issues with the header. Fix this by removing the pre-check.
The pre-check was likely introduced on top of
ada0caa165 to fix UB in
GetWitnessCommitmentIndex in case a block's transactions are empty. This
code path could only be reached because of the call to
UpdateUncommittedBlockStructures in submitblock, but cannot be reached
through net_processing.
Add some functional test cases to cover the previous conditions that
lead to a "Block does not start with a coinbase" json rpc error being
returned.

kernel library, bitcoin-chainstate, imitates these checks, the other
interfaces do not.
Recently added mempool_util implementation probably evolved in parallel with the package RBF one before being submitted as part of ephemeral dust in e2e30e89ba.

Pull request description:
part of cluster mempool: #30289
It became clear while working on cluster mempool that it would be helpful for transaction validation if we could consider a full set of proposed changes to the mempool -- consisting of a set of transactions to add, and a set of transactions (ie conflicts) to simultaneously remove -- and perform calculations on what the mempool would look like if the proposed changes were to be applied. Two specific examples of where we'd like to do this:
- Determining if ancestor/descendant/TRUC limits would be violated (in the future, cluster limits) if either a single transaction or a package of transactions were to be accepted
- Determining if an RBF would make the mempool "better", however that idea is defined, both in the single transaction and package of transaction cases
In preparation for cluster mempool, I have pulled this reworking of the mempool interface out of #28676 so it can be reviewed on its own. I have not re-implemented ancestor/descendant limits to be run through the changeset, since with cluster mempool those limits will be going away, so this seems like wasted effort. However, I have rebased #28676 on top of this branch so reviewers can see what the new mempool interface could look like in the cluster mempool setting.
There are some minor behavior changes here, which I believe are inconsequential:
- In the package validation setting, transactions would be added to the mempool before the `ConsensusScriptChecks()` are run. In theory, `ConsensusScriptChecks()` should always pass if the `PolicyScriptChecks()` have passed and it's just a belt-and-suspenders for us, but if somehow they were to diverge then there could be some small behavior change from adding transactions and then removing them, versus never adding them at all.
- The error reporting on `CheckConflictTopology()` has slightly changed due to no longer distinguishing between direct conflicts and indirect conflicts. I believe this should be entirely inconsequential because there shouldn't be a logical difference between those two ideas from the perspective of this function, but I did have to update some error strings in some tests.
- Because, in a package setting, RBFs now happen as part of the entire package being accepted, the logging has changed slightly because we do not know which transaction specifically evicted a given removed transaction.
- Specifically, the "package hash" is now used to reference the set of transactions that are being accepted, rather than any single txid. The log message relating to package RBF that happen in the `TXPACKAGES` category has been updated as well to include the package hash, so that it's possible to see which specific set of transactions are being referenced by that package hash.
- Relatedly, the tracepoint logging in the package rbf case has been updated as well to reference the package hash, rather than a transaction hash.

Pull request description:
A repeating pattern in the functional tests is that the test sleeps for a while to ensure that a certain condition is still true after some amount of time has elapsed. Most recently a new case of this was added in #30807. This PR here introduces an `ensure` helper to streamline this functionality.
Some approach considerations:
- It is possible to construct this by reusing `wait_until` and wrapping it in `try` internally. However, the logger output of the failing wait would still be printed which seems irritating. So I opted for simplified but similar internals to `wait_until`.
- This implementation starts for a failure in the condition right away which has the nice side-effect that it might give feedback on a failure earlier than is currently the case. However, in some cases, it may be expected that the condition may still be false at the beginning and then turns true until time has run out, something that would work when the test sleeps without checking in a loop. I decided against this design (and even against adding it as an option) because such a test design seems like it would be racy either way.
- I have also been going back and forth on naming. To me `ensure` works well but I am also not a native speaker, happy consider a different name if others don't think it's clear enough.

Pull request description:
`m_best_header` (the most-work header not known to be on an invalid chain) can be wrong in the context of invalidation / reconsideration of blocks. This can happen naturally (a valid header is received and stored in our block tree db; when the full block arrives, it is found to be invalid) or triggered by the user with the `invalidateblock` / `reconsiderblock` rpc.
We don't currently use `m_best_header` for any critical things (see OP of #16974 for a list that still seems up-to-date), so it being wrong affects mostly rpcs.
This PR proposes to recalculate it if necessary by looping over the block index and finding the best header. It also suggest to mark headers between an invalidatetd block and the previous `m_best_header` as invalid, so they won't be considered in the recalculation.
It adds tests to `rpc_invalidateblock.py` and `rpc_getchaintips.py` that fail on master.
One alternative to this suggested in the past would be to introduce a continuous tracking of header tips (#12138).
While this might be more performant, it is also more complicated, and situations where we need this data are only be remotely triggerable by paying the cost of creating a valid PoW header for an invalid block.
Therefore I think it isn't necessary to optimise for performance here, plus the solution in this PR doesn't perform any extra steps in the normal node operation where no invalidated blocks are encountered.

After port collisions are no longer tolerated but lead to
a startup failure in v28.0, local setups of multiple nodes,
each with a different -port value would not be possible anymore
due to collision of the onion default port - even if the nodes
were using tor or not interested in receiving onion inbound connections.
Fix this by deriving the onion listening port to be -port + 1.

The mempool:replaced tracepoint now reports either a txid or a
package hash (previously it always was a txid). To let users know
if a txid or package hash is passed, a boolean argument is added
the the tracepoint.
In the functional test, a ctypes.Structure class for MempoolReplaced
is introduced as Python warns the following when not explcitly
casting it to a ctype:
Type: 'bool' not recognized. Please define the data with ctypes manually.

Pull request description:
A replacement for https://github.com/bitcoin/bitcoin/pull/29001
Now that we have 1P1C relay, TRUC transactions and sibling eviction, it makes sense to retarget this feature more narrowly by not introducing a new output type, and simple focusing on the feature of allowing temporary dust in the mempool.
Users of this can immediately use dust outputs as:
1. Single keyed anchor (can be shared by multiple parties)
2. Single unkeyed anchor, ala P2A
Which is useful when the parent transaction cannot have fees for technical or accounting reasons.
What I'm calling "keyed" anchors would be used anytime you don't want a third party to be able to run off with the utxo. As a motivating example, in Ark there is the concept of a "forfeit transaction" which spends a "connector output". The connector output would ideally be 0-value, but you would not want that utxo spend by anyone, because this would cause financial loss for the coordinator of the service: https://arkdev.info/docs/learn/concepts#forfeit-transaction
Note that this specific use-case likely doesn't work as it involves a tree of dust, but the connector idea in general demonstrates how it could be used.
Another related example is connector outputs in BitVM2: https://bitvm.org/bitvm2.html .
Note that non-TRUC usage will be impractical unless the minrelay requirement on individual transactions are dropped in general, which should happen post-cluster mempool.
Lightning Network intends to use this feature post-29.0 if available: https://github.com/lightning/bolts/issues/1171#issuecomment-2373748582
It's also useful for Ark, ln-symmetry, spacechains, Timeout Trees, and other constructs with large presigned trees or other large-N party smart contracts.
