Previously, TX_WITNESS_MUTATED could be returned during transaction validation
for either transactions that had a witness that was non-standard, or for
transactions that had no witness but were invalid due to segwit validation
rules.
However, for txid/wtxid-relay considerations, net_processing distinguishes the
witness stripped case separately, because it affects whether a wtxid should be
able to be added to the reject filter. It is safe to add the wtxid of a
witness-mutated transaction to the filter (as that wtxid shouldn't collide with
the txid, and hence it wouldn't interfere with transaction relay from
txid-relay peers), but it is not safe to add the wtxid (== txid) of a
witness-stripped transaction to the filter, because that would interfere with
relay of another transaction with the same txid (but different wtxid) when
relaying from txid-relay peers.
Also updates the comment explaining this logic, and explaining that we can get
rid of this complexity once there's a sufficient deployment of wtxid-relaying
peers on the network.
Using both txid and wtxid-based relay with peers means that we could sometimes
download the same transaction twice, if announced via two different hashes from
different peers.
Use a heuristic of delaying txid-peer-getdata requests by 2 seconds, if we have
at least one wtxid-based peer.
This adds a field to CNodeState that tracks whether to relay transactions with
that peer via wtxid, instead of txid. As of this commit the field will always
be false, but in a later commit we will add a way to negotiate turning this on
via p2p messages exchanged with the peer.
Previously, we only added txids to recentRejects if we were sure that the
transaction couldn't have had the wrong witness (either because the witness was
malleated or stripped).
In preparation for wtxid-based relay, we can observe that txid == wtxid for
transactions that have no witness, and add the wtxid of rejected transactions,
provided the transaction wasn't a witness-stripped one. This means that we now
add more data to the filter (as prior to this commit, any transaction with a
witness that failed to be accepted was being skipped for inclusion in the
filter) but witness malleation should still not interfere with relay of a valid
segwit transaction, because the txid of a segwit transaction would not be added
to the filter after failing validation.
In the future, having wtxids in the recent rejects filter will allow us to
skip downloading the same wtxid multiple times, once our peers use wtxids for
transaction relay.
This is in preparation for wtxid-based invs (we need to be able to tell whether
we AlreadyHave() a transaction based on either txid or wtxid).
This also double the size of the bloom filter, which is overkill, but still
uses a manageable amount of memory.

Again, to keep the review burden managable, the changes are kept simple,

fa8ec00061 rpc: Check that left section is not multiline (MarcoFalke)
Pull request description:
This is split out from #18531 to just touch the RPC methods in server. Description from the main pr:
### Motivation
RPCArg names in the rpc help are currently only used for documentation. However, in the future they could be used to teach the server the named arguments. Named arguments are currently registered by the `CRPCCommand`s and duplicate the RPCArg names from the documentation. This redundancy is fragile, and has lead to errors in the past (despite having linters to catch those kind of errors). See section "bugs found" for a list of bugs that have been found as a result of the changes here.
### Changes
The changes here add an assert in the `CRPCCommand` constructor that the RPCArg names are identical to the ones in the `CRPCCommand`.
### Future work
> Here or follow up, makes sense to also assert type of returned UniValue?
Sure, but let's not get ahead of ourselves. I am going to submit any further works as follow-ups, including:
* Removing the CRPCCommand arguments, now that they are asserted to be equal and thus redundant
* Removing all python regex linters on the args, now that RPCMan can be used to generate any output, including the cli.cpp table
* Auto-formatting and sanity checking the RPCExamples with RPCMan
* Checking passed-in json in self-check. Removing redundant checks
* Checking returned json against documentation to avoid regressions or false documentation
* Compile the RPC documentation at compile-time to ensure it doesn't change at runtime and is completely static
### Bugs found
* The assert identified issue #18607
* The changes itself fixed bug #19250

b82f0ca4d5 walletdb: Add MakeBatch function to BerkeleyDatabase and use it (Andrew Chow)
eac9200814 walletdb: Refactor DatabaseBatch abstract class from BerkeleyBatch (Andrew Chow)
Pull request description:
In order to support alternative database systems, we need to have a generic `Batch` class. This PR adds a `DatabaseBatch` abstract class which is implemented by `BerkeleyBatch`. `DatabaseBatch` is now the class that is used by `WalletBatch` to interact with the database. To be able to get the correct type of `DatabaseBatch`, `BerkeleyDatabase` now has a `MakeBatch` function which returns a newly constructed `std::unique_ptr<DatabaseBatch>`. For `BerkeleyDatabase`, that will be `std::unique_ptr<BerkeleyBatch>`.
The `Read`, `Write`, `Erase`, and `Exists` template functions are moved from `BerkeleyBatch`.

fa9f20b647 log: Properly log txs rejected from mempool (MarcoFalke)
Pull request description:
Currently `CheckTxInputs` rejections from the mempool are the only rejections that log directly and unconditionally to debug.log instead of leaving it to the caller. This has multiple issues:
* A rejected RPC transaction will log a redundant failure reason to debug log. All other failures are merely reported to the RPC user.
* A rejected p2p transaction will log the failure twice. Once with the `MEMPOOLREJ` flag, and once unconditionally.
* A rejected orphan transaction will log no failure.
Fix all issues by simply returning the state to the caller, like it is done for all other rejections.
The patch includes whitespace fixups to highlight relevant parts of the codebase and simplify review.

Pull request description:
This implements the follow-up suggested here: https://github.com/bitcoin/bitcoin/pull/18861#issuecomment-627630111 . Instead of checking `setInventoryTxToSend`, maintain an explicit bloom filter with the 3500 most recently announced invs, and permit fetching any of these as long as they're in the relay pool or the mempool. In addition, permit relay from the mempool after just 2 minutes instead of 15.
This:
* Fixes the brief opportunity an attacker has to request unannounced invs just after the connection is established (pointed out by naumenkogs, see https://github.com/bitcoin/bitcoin/pull/18861#issuecomment-627627010).
* Guarantees that locally resubmitted invs after `filterInventoryKnown` rolls over can still be requested (pointed out by luke-jr, see https://github.com/bitcoin/bitcoin/pull/18861#discussion_r419695831).
It adds 37 KiB of filter per peer.
This is also a step towards dropping the relay pool entirely and always relaying from the mempool directly (see #17303), but that is still blocked by dealing properly with NOTFOUNDs (see #18238).

Instead of removing the database transaction logs and retrying the
wallet loading, just return an error message to the user. Additionally,
specifically for DB_RUNRECOVERY, notify the user that this could be due
to different BDB versions. This error is pretty much only caused by
compiling with a newer version of BDB and then trying to open the wallet
with a version compiled with an older version of BDB.
Qt tests currently are currently using two NodeContext structs at the same
time, one in interfaces::NodeImpl::m_context, and the other in
BasicTestingSetup::m_node, and the tests have hacks transferring state between
them.
Fix this by getting rid of the NodeImpl::m_context struct and making it a
pointer. This way a common BitcoinApplication object can be used for all qt
tests, but they can still have their own testing setups.
Non-test code is changing but non-test behavior is still the same as before.
Motivation for this PR is to be able to remove the
"std::move(test.m_node.connman)" and mempool hacks for swapping individual
NodeContext members in Qt tests, because followup PR #19099 adds yet another
member (wallet_client) that needs to be swapped. After this change, the whole

08fc6f6cfc [rpc] refactor: consolidate sendmany and sendtoaddress code (Sjors Provoost)
Pull request description:
I consolidated code between these two RPC calls, since `sendtoaddress` is essentially `sendmany` with 1 destination.
Unless I overlooked something, the only behaviour change is that some `sendtoaddress` error codes changed from `-4` to `-6`. The release note mentions this.
Salvaged from #18201.

a66a7a1a70 walletdb: don't reinitialize desc cache with multiple cache entries (Andrew Chow)
Pull request description:
When loading descriptor caches, we would accidentally reinitialize the descriptor cache when seeing that one already exists. This should have only been initializing the cache when one does not exist. However this code itself is unnecessary as the act of looking up the cache to add to it will initialize it if it didn't already exist.
This issue could be hit by trying to load a wallet that had imported a multisig descriptor. The wallet would fail to load.
A test has been added to wallet_importdescriptors.py to catch this case. Another test case has also been added to check that loading a wallet with only single key descriptors works.

0122fbab4c Split SetHDChain into AddHDChain and LoadHDChain (Andrew Chow)
Pull request description:
`SetHDChaiin`, `SetActiveScriptPubKeyMan`, and `SetWalletFlags` have a `memonly` argument which is kind of confusing, as noted in https://github.com/bitcoin/bitcoin/pull/17681#discussion_r427633081. This PR replaces those functions with `Add*` and `Load*` variants so that they follow the pattern used elsewhere in the wallet.
`AddHDChain`, `AddActiveScriptPubKeyMan`, and `AddWalletFlags` both set their respective variables in `CWallet` and writes them to disk. These functions are used by the actions which modify the wallet such as `sethdseed`, `importdescriptors`, and creating a new wallet.
`LoadHDChain`, `LoadActiveScriptPubKeyMan`, and `LoadWalletFlags` just set the `CWallet` variables. These functions are used by `LoadWallet` when loading the wallet from disk.

fab5586122 doc: Use precise permission flags where possible (MarcoFalke)
Pull request description:
Instead of mentioning the all-encompassing `-whitelist*` settings, change the docs to mention the exact permission flag that will influence the behaviour.
This is needed because in the future, the too-broad `-whitelist*` settings (they either include *all* permission flags or apply to *all* peers) might be deprecated to require the permission flags to be enumerated.
Alternatively, in the future there could be an RPC to set the net permission flags on an existing connection, in which case the `-whitelist*` terminology is of no help.

If we don't disconnect a peer in MaybeDiscourageAndDisconnect because it
has NOBAN permissions or it's a manual connection, continue SendMessages
processing rather than exiting early.
The previous behaviour was that we'd miss the SendMessages processing on
this iteration of the MessageHandler loop. That's not a problem since
SendMessages() would just be called again on the next iteration, but it
was slightly inefficient and confusing.
`nMisbehavior` is a tally in `CNodeState` that can be incremented from
anywhere. That almost always happens inside a `ProcessMessages()` call
(because we increment the misbehavior score when receiving a bad
messages from a peer), but not always. See, for example, the call to
`MaybePunishNodeForBlock()` inside `BlockChecked()`, which is an
asynchronous callback from the validation interface, executed on the
scheduler thread.
As long as `MaybeDiscourageAndDisconnect()` is called regularly for the
node, then the misbehavior score exceeding the 100 threshold will
eventually result in the peer being punished. It doesn't really matter
where that `MaybeDiscourageAndDisconnect()` happens, but it makes most
sense in `SendMessages()` which is where we do general peer
housekeeping/maintenance.
Therefore, remove the `MaybeDiscourageAndDisconnect()` call in
`ProcessMessages()` and move the `MaybeDiscourageAndDisconnect()` call
in `SendMessages()` to the top of the function. This moves it out of the
cs_main lock scope, so take that lock directly inside
`MaybeDiscourageAndDisconnect()`.
Historic note: `MaybeDiscourageAndDisconnect()` was previously
`SendRejectsAndCheckIfBanned()`, and before that was just sending
rejects. All of those things required cs_main, which is why
`MaybeDiscourageAndDisconnect()` was called after the ping logic.
20d31bdd92 tests: Avoid fuzzer-specific nullptr dereference in libevent when handling PROXY requests (practicalswift)
Pull request description:
Avoid constructing requests that will be interpreted by libevent as PROXY requests to avoid triggering a `nullptr` dereference. Split out from #19074 as suggested by MarcoFalke.
The dereference (`req->evcon->http_server`) takes place in `evhttp_parse_request_line` and is a consequence of our hacky but necessary use of the internal function `evhttp_parse_firstline_` in the `http_request` fuzzing harness.
The suggested workaround is not aesthetically pleasing, but it successfully avoids the troublesome code path.

This was changed to TRY_LOCK in #1117 to fix a potential deadlock
between cs_main and cs_vSend. cs_vSend was split into cs_vSend and
cs_sendProcessing in #9535 (and cs_sendProcessing was changed from a
TRY_LOCK to a LOCK in the same PR).
Since cs_vSend can no longer be taken before cs_main, revert this to a
LOCK().
This commit leaves part of the code with bad indentation. That is fixed
by the next (whitespace change only) commit.

It should be possible to grant nodes in a local network (e.g. home, university, enterprise, ...) permission to download blocks even after the maxuploadtarget is hit.
Currently this is only possible by setting the `noban` permission, which has some adverse effects, especially if the peers can't be fully trusted.
Fix this by extracting a `download` permission from `noban`.

... unless they're UNCONDITIONAL_RELAY_DELAY old, or there has been
a response to a MEMPOOL request in the mean time.
This is accomplished using a rolling Bloom filter for the last
3500 announced transactions. The probability of seeing more than 100
broadcast events (which can be up to 35 txids each) in 2 minutes for
an outbound peer (where the average frequency is one per minute), is
less than 1 in a million.
This constant is set to 2 minutes, rather than 15. This is still many times
larger than the transaction broadcast interval (2s for outbound, 5s for
inbound), so it should be acceptable for peers to know what our contents of
the mempool was that long ago.

Pull request description:
This is another intermediate part of the Coinstats Index (tracked in #18000).
Sjors suggested [here](https://github.com/bitcoin/bitcoin/pull/18000#issuecomment-641423019) that the part of the changes in #19145 that don't rely on the new `hash_type` muhash, i.e. that are for `hash_type=none`, could be merged separately from everything involving muhash. So these changes are extracted from #19145 here and can be merged without any other requirements.
Building the index with no UTXO set hash is still valuable because `gettxoutsetinfo` can still be used to audit the `total_amount` for example. By itself this PR is not a huge improvement, `hash_type=none` is speeding up `gettxoutsetinfo` by about 10%, but it enables the implementation of an index on top of it in a follow-up and that means large parts of the index code of Coinstats Index can be merged while reviews for the hashing algorithm might take longer.

8f1bcf8b7b walletdb: Combine VerifyDatabaseFile and VerifyEnvironment (Andrew Chow)
Pull request description:
The `BerkeleyBatch` class has 4 static functions that operate on `BerkeleyDatabase` or `BerkeleyEnvironment`. It doesn't make sense for these to be standalone nor for them to be static functions. So instead, move them from `BerkeleyBatch` into `BerkeleyDatabase` and make them member functions instead of static.
`BerkeleyBatch::VerifyEnvironment` and `BerkeleyBatch::VerifyDatabaseFile` are combined into a single `BerkeleyDatabase::Verify` function that operates on that `BerkeleyDatabase` object.
`BerkeleyBatch::Rewrite` and `BerkeleyBatch::PeriodicFlush` both took a `BerkeleyDatabase` as an argument and did stuff on it. So we just make it a member function so it doesn't need to take a database as an argument.

This patch improves performance and resource usage around IP
addresses that are banned for misbehavior. They're already not
actually banned, as connections from them are still allowed,
but they are preferred for eviction if the inbound connection
slots are full.
Stop treating these like manually banned IP ranges, and instead
just keep them in a rolling Bloom filter of misbehaving nodes,
which isn't persisted to disk or exposed through the ban
framework. The effect remains the same: preferred for eviction,
avoided for outgoing connections, and not relayed to other peers.
Also change the name of this mechanism to better reflect reality;
they're not banned, just discouraged.
Contains release notes and several interface improvements by
John Newbery.
When loading descriptor caches, we would accidentally reinitialize the
descriptor cache when seeing that one already exists. This should have
only been initializing the cache when one does not exist. However this
code itself is unnecessary as the act of looking up the cache to add to
it will initialize it if it didn't already exist.
This issue could be hit by trying to load a wallet that had imported a
multisig descriptor. The wallet would fail to load.
A test has been added to wallet_importdescriptors.py to catch this case.
Another test case has also been added to check that loading a wallet
with only single key descriptors works.
fa0dfdf447 refactor: Remove confusing BlockIndex global (MarcoFalke)
Pull request description:
The global `::BlockIndex()` is problematic for several reasons:
* It returns a mutable reference to the block tree, without the appropriate lock annotation (`m_block_index` is guarded by `cs_main`). The current code is fine, but in the future this might lead to accidental races and data corruption.
* The rpc server shouldn't rely on node globals, but rather a context that is passed in to the RPC method.
* Tests might want to spin up their own block tree, and thus should also not rely on a single global.
Fix all issues by removing the global

72f6bec1da rpc: show both UTXOs in decodepsbt (Andrew Chow)
Pull request description:
Due to recent changes to hardware wallets, the full previous transaction will need to be provided for segwit inputs. Since some software may be checking for the existence of a `witness_utxo` to determine whether to produce a segwit signature, we keep that field to ease the transition.
Because all of the sanity checks implemented by the `IsSane` functions were related to having mixed segwit and non-segwit data in a PSBT, those functions are removed as those checks are no longer proper.
Some tests are updated/removed to accommodate this and a simple test added to check that both UTXOs are being added to segwit inputs.
As discussed in the wallet IRC meeting, our own signer will not require `non_witness_utxo` for segwit inputs.

Also adds CCoinsViewCache::ReallocateCache() to attempt to free
memory that the cacheCoins's allocator may be hanging onto when
downsizing the cache.
Adds `CChainState::m_coins{tip,db}_cache_size_bytes` data members
so that we can reference cache size on a per-chainstate basis for
flushing.
We'll need this to dynamically update the cache size of the existing
CCoinsViewDB instance when we create a new one during snapshot activation.
This requires us to keep the CDBWrapper instance as a pointer instead of
a reference so that we're able to destruct it and create a new instance
when the cache size changes.
Also renames `db` to `m_db` since we're already modifying each usage.
Includes feedback from Russ Yanofsky.

The change in default happened in [Boost 1.39.0](https://www.boost.org/users/history/version_1_39_0.html) (along with the introduction of the Signals2 library.
More information is also available here https://www.boost.org/doc/libs/1_73_0/doc/html/signals2/rationale.html#id-1.3.36.9.4:
> The default combiner for Boost.Signals2 has changed from the last_value combiner used by default in the original Boost.Signals library.
> This is because last_value requires that at least 1 slot be connected to the signal when it is invoked (except for the last_value<void> specialization).
> In a multi-threaded environment where signal invocations and slot connections and disconnections may be happening concurrently, it is difficult to fulfill this requirement. When using optional_last_value, there is no requirement for slots to be connected when a signal is invoked, since in that case the combiner may simply return an empty boost::optional.

fa0f6c58c1 Revert "Fix link error with --enable-debug" (MarcoFalke)
Pull request description:
This reverts a hacky workaround from commit b83cc0f, which only happens to work due to compiler optimizations. Then, it actually fixes the linker error.
The underlying problem is that the wallet includes symbols from the server (ui_interface), which usually results in linker failures. Though, in this specific case the linker failures have not been observed (unless `-O0`) because our compilers were smart enough to strip unused symbols.
Fix the underlying problem by creating a new header-only with the needed symbol and move ui_interface to node to clarify that this is part of libbitcoin_server.

Pull request description:
The functions that could lock this mutex, i.e., `SetRPCWarmupStatus()`, `SetRPCWarmupFinished()`, `RPCIsInWarmup()`, `CRPCTable::execute()`, do not call itself recursively, and do not call each other either directly or indirectly. Therefore, the `g_rpc_warmup_mutex` could be a non-recursive mutex.

This can be tested by running in parallel the following script a couple of times:
```sh

src/bitcoin-cli -regtest loadwallet foo
src/bitcoin-cli -regtest unloadwallet foo
done
```
Eventually the error occurs:
```
error code: -4

```
For reference, loading and already loaded wallet gives:
```
error code: -4
error message:
Wallet file verification failed. Error loading wallet w1. Duplicate -wallet filename specified.

9952242c03 build: improve builtin_clz* detection (fanquake)
Pull request description:
Fixes#19402.
The way we currently test for `__builtin_clz*` support with `AC_CHECK_DECLS` does not work with Clang:
```bash
configure:21492: clang++-10 -std=c++11 -c -g -O2 -DHAVE_BUILD_INFO -D__STDC_FORMAT_MACROS conftest.cpp >&5
conftest.cpp💯10: error: builtin functions must be directly called
(void) __builtin_clz;
^
1 error generated.
```
This also removes the `__builtin_clz()` check, as we don't actually use it anywhere, and it's trvial to re-add detection if we do start using it at some point. If this is controversial then I'll add a test for it as well.

0ac09c9793 qt: Do not truncate node flag strings in debugwindow.ui peers details tab. (saibato)
Pull request description:
Fix: When fiddling around with new node flags other than the usual.
I saw that not all possible node flag strings i.e. the UNKNOWN[..] where
visible in peers details tab.
Since v18.2 fixed size was set to 300 and sliding is thereby limited.
A fix on my old linux cruft and small screen was to set minimumSize width to -1 or 0.
Qt will then autosize the slider to the max string length.
Thereby i had full display of all flags inclusive sliding without to fullscreen the window.
Not sure if this is even an issue for those who can afford big screens or high res macs?
Feedback welcome.
BTW: nice side effect now again easy to scroll trough long version names of the node.
can't wait to see strings like /Satoshi:0.23.99/NOX2NOX4NOX32 or what ever fits in the version string.

1087807b2b tests: Provide main(...) function in fuzzer (practicalswift)
Pull request description:
Provide `main(...)` function in fuzzer. Allow building uninstrumented harnesses with only `--enable-fuzz`.
This PR restores the behaviour to how things worked prior to #18008. #18008 worked around an macOS specific issue but did it in a way which unnecessarily affected platforms not in need of the workaround :)
Before this patch:
```
# Build uninstrumented fuzzing harness (no libFuzzer/AFL/other-fuzzer-instrumentation)
$ ./configure --enable-fuzz
$ make
CXXLD test/fuzz/span
/usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/Scrt1.o: In function `_start':
(.text+0x20): undefined reference to `main'
collect2: error: ld returned 1 exit status
Makefile:7244: recipe for target 'test/fuzz/span' failed
make[2]: *** [test/fuzz/span] Error 1
make[2]: *** Waiting for unfinished jobs....
$
```
After this patch:
```
# Build uninstrumented fuzzing harness (no libFuzzer/AFL/other-fuzzer-instrumentation)
$ ./configure --enable-fuzz
$ make
$ echo foo | src/test/fuzz/span
$
```
The examples above show the change in non-macOS functionality. macOS functionality is unaffected by this patch.

37ae687f95 Add tests for CPubKey serialization/unserialization (Elichai Turkel)
9b8907fade Check size after Unserializing CPubKey (Elichai Turkel)
Pull request description:
Found by practicalswift, closes#19235
Currently all the public API(except the pointer-like API) in CPubKey that sets/constructs a pubkey goes through `CPubKey::Set` which checks if that the length and size match and if not invalidates the key.
This adds the same check to `CPubKey::Unserialize`, sadly I don't see an easy way to just push this to the existing checks in `CPubKey::Set` but it's only a simple condition.
The problem with not invalidating is that if you write a pubkey like: `{0x02,0x00}` it will think the actual length is 33(because of `size()`) and will access uninitialized memory if you call any of the functions on CPubKey.

4f9d9efb4e qt: Remove needless headers (Hennadii Stepanov)

This is a small followup of https://github.com/bitcoin/bitcoin/pull/18027.
Top commit has no ACKs.
Tree-SHA512: 986ed5c8f3bac4c0053736ce84d738f8593d3dbf713109af3cb9b7051cd838f23152a39bb3c1e9694a993c4e7accf14e94e5beff5e7881155638cd44fbf7f46f
This adds static asserts that ensure that the default values given for
fee levels in the wallet (minimum fee and incremental feerate increase)
are at least as high as the corresponding levels configured in the
core node policy.
The TRY_LOCK(cs_inventory) in DisconnectNodes() is taken after the CNode
object has been removed from vNodes and when the CNode's nRefCount is
zero.
The only other places that cs_inventory can be taken are:
- In ProcessMessages() or SendMessages(), when the CNode's nRefCount
must be >0 (see ThreadMessageHandler(), where the refcount is
incremented before calling ProcessMessages() and SendMessages()).
- In a ForEachNode() lambda in PeerLogicValidation::UpdatedBlockTip().
ForEachNode() locks cs_vNodes and calls the function on the CNode
objects in vNodes.
Therefore, cs_inventory is never locked by another thread when the
TRY_LOCK(cs_inventory) is reached in DisconnectNodes(). Since the
only purpose of this TRY_LOCK is to ensure that the lock is not
taken by another thread, this always succeeds. Remove the check.
PushBlockInventory() and PushBlockHash() are functions that can
be replaced with single-line statements. This also eliminates
the single place that cs_inventory is taken recursively.
Instead of returning a Dbc (BDB cursor object) and having the caller
deal with the cursor, make BerkeleyBatch handle the cursor internally.
This prepares BerkeleyBatch to work with other database systems as Dbc
objects are BDB specific.
Not all possible node flags are visible in details of peers tab since v18.2.
qt will now autoadapt the slider to the full string size.

Pull request description:
Add a "PSBT Operations" dialog, reached from the "Load PSBT..." menu item, giving options to sign or broadcast the loaded PSBT as appropriate, as well as copying the result to the clipboard or saving it to a file.
This is based on Sjors' #17509, and depends on that PR going in first. (It effectively replaces the small "load PSBT" dialog from that PR with a more feature-rich one.)
Some notes:
* The way I display status information is maybe unusual (a status bar, rather than messageboxes.) I think it's helpful to have the information in it be persistent rather than transitory. But if people dislike it, I would probably move the "current state of the transaction" info to the top line of the main label, and the "what action just happened, and did it succeed" info into a messagebox.
* I don't really know much about the translation/localization stuff. I put tr() in all the places it seemed like it ought to go. I did not attempt to translate the result of TransactionErrorString (which is shared by GUI and non-GUI code); I don't know if that's correct, but it matches the "error messages in logs should be googleable in English" heuristic. I don't know whether there are things I should be doing to reduce translator effort (like minimizing the total number of distinct message strings I use, or something.)
* I don't really know how (if?) automated testing is applied to GUI code. I can make a list of PSBTs exercising all the codepaths for manual testing, if that's the right approach. Input appreciated.

Pull request description:
This PR continues and completes the work begun in #17700 working on issue #16000 to create a client-side version of RPC `generate`.
Basically, `bitcoin-cli -generate` wraps calling `generatenewaddress` followed by `generatetoaddress [nblocks] [maxtries]` and prints the following:
```
$ bitcoin-cli -generate
{
"address": "bcrt1qn4aszr2y2xvpa70y675a76wsu70wlkwvdyyln6"
"blocks": [
"01d2ebcddf663da90b28da7f6805115e2ba7818f16fe747258836646a43a0bb5",
]
}
$ bitcoin-cli -rpcwallet=wallet-name -generate 3 100
{
"address": "bcrt1q4cunfw0gnsj7g7e6mk0v0uuvvau9mwr09dj45l",
"blocks": [
"7a6650ca5e0c614992ee64fb148a7e5e022af842e4b6003f81abd8baf1e75136",
"01d2ebcddf663da90b28da7f6805115e2ba7818f16fe747258836646a43a0bb5",
"3f8795ec40b1ad812b818c177680841be319a3f6753d4e32dc7dfb5bafe5d00e"
]
}
```
Help doc:
```
$ bitcoin-cli -h | grep -A5 "\-generate"
-generate
Generate blocks immediately, equivalent to RPC generatenewaddress
followed by RPC generatetoaddress. Optional positional arguments
are number of blocks to generate (default: 1) and maximum
iterations to try (default: 1000000), equivalent to RPC
generatetoaddress nblocks and maxtries arguments. Example:
bitcoin-cli -generate 4 1000
```
Quite a bit of test coverage turned out to be needed to cover the change and the different cases (arguments, multiwallet mode) and error-handling.
This PR also improves some things that working on these changes brought to light.
Credit to Harris Brakmić for the initial work in #17700.

cc29d1e2c4 [tools] Update clang-format config (John Newbery)
Pull request description:
In some cases, running clang-format has made code _less_ readable by joining declarations and calls for functions with many arguments into very long lines. For example:
```
- size_t getQueueInfo(std::chrono::system_clock::time_point &first,
- std::chrono::system_clock::time_point &last) const;
+ size_t getQueueInfo(std::chrono::system_clock::time_point& first, std::chrono::system_clock::time_point& last) const;
```
(https://github.com/bitcoin/bitcoin/pull/19090#discussion_r431961148)
This change to clang-format would allow arguments/parameters for func declarations/calls to be split over multiple lines, aligned with the opening parens. It does not force args/params to be on new lines (that setting is `BinPackParameters : true`).

Pull request description:
These were deprecated in #17578 and #17585, with expected 0.21 removal notified in the 0.20 release notes.
```
- The `getaddressinfo` RPC has had its `label` field deprecated
(re-enable for this release using the configuration parameter
`-deprecatedrpc=label`). The `labels` field is altered from returning
JSON objects to returning a JSON array of label names (re-enable
previous behavior for this release using the configuration parameter
`-deprecatedrpc=labelspurpose`). Backwards compatibility using the
deprecated configuration parameters is expected to be dropped in the
0.21 release. (#17585, #17578)

e5327f947c [rpc] fundrawtransaction: add_inputs option to control automatic input adding (Sjors Provoost)
79804fe24b [rpc] walletcreatefundedpsbt: don't automatically append inputs (Sjors Provoost)
Pull request description:
When the user doesn't specificy inputs, it makes sense to automatically select them. But when the user does specify inputs, `walletcreatefundedpsbt` now fails if the amount is insufficient, unless `addInputs` is set to `true`.
Similarly for `fundrawtransaction` if the original transaction already specified inputs, we only add more if `addInputs` is set to `true`.
This protects against fat finger mistakes in the amount or fee rate (see also #16257). The behavior is also more similar to GUI coin selection.

A templated BaseHash does not allow for automatic conversion, thus
conversions much be explicitly allowed / whitelisted, which will
reduce the risk of unintended conversions.
These types are equivalent, in data etc, so they need only their
data cast across.
Note a function is used rather than a casting
operator as CKeyID is defined at a lower level than script/standard

In FillPSBT, optionally report the number of inputs we successfully
signed, as an out parameter. If "sign" is false, instead report the
number of inputs for which GetSigningProvider does not return nullptr.
(This is a potentially overbroad estimate of inputs we could sign.)

Pull request description:
This improves our Span class by making it closer to the C++20 `std::span` one:
* ~~Support conversion between compatible Spans (e.g. `Span<char>` to `Span<const char>`).~~ (done in #18591)
* Make the size type `std::size_t` rather than `std::ptrdiff_t` (the C++20 one underwent the same change).
* Support construction of Spans directly from arrays, `std::string`s, `std::array`s, `std::vector`s, `prevector`s, ... (for all but arrays, this only works for const containers to prevent surprises).
And then make use of those improvements in various call sites.
I realize the template magic used looks scary, but it's only needed to make overload resultion make the right choices. Note that the operations done on values are all extremely simple: no casts, explicit conversions, or warning-silencing constructions. That should hopefully make it simpler to review.

While doing some moveonly stuff, an additional commit moves the `*Cursor` and `Txn*` implementations out of the header file and into the cpp file.

44cc75f80e wallet: error if an explicit fee rate was given but the needed fee rate differed (Karl-Johan Alm)
Pull request description:
This ensures that the code doesn't silently ignore too low fee reates. It will now trigger an error in the QT client, if the user provides a fee rate below the minimum, and becomes a necessary check for #11413.

313a081b90 [net] Add seed.bitcoin.wiz.biz to DNS seeds (wiz)
Pull request description:
I've created the `seed.bitcoin.wiz.biz` DNS seed for the benefit of the Bitcoin community, and will operate it in accordance with the [Bitcoin DNS seed operator policy](https://github.com/bitcoin/bitcoin/blob/master/doc/dnsseed-policy.md). Since this is my first PR to the Bitcoin Core project, I also ACK the [contributing guidelines](https://github.com/bitcoin/bitcoin/blob/master/CONTRIBUTING.md).
The data for this DNS seed is generated using redundant instances of TheBlueMatt's [dnsseed-rust implementation](https://github.com/TheBlueMatt/dnsseed-rust), which connects to all discoverable Bitcoin nodes to verify their capabilities and speed, and utilizes the full AS-MAP data from my network's BGP tables to select Bitcoin nodes which are fairly distributed across different networks.
As for my qualifications, I currently operate Bitcoin nodes for the [mempool.space](https://mempool.space/) open-source block explorer project (mempool) and the [Bisq Network](https://bisq.network/) open-source P2P trading community (bisq-network). I have 20 years experience as a network engineer, and all of [my Bitcoin nodes](https://bitnodes.io/nodes/?q=AS54415) are hosted on [my own network](https://ipinfo.io/AS54415) across multiple datacenters. For personal references, the current Bitcoin DNS seed operators Emzy and TheBlueMatt can probably vouch for me.
The DNS responses served from this instance are currently served with a TTL of 60 seconds, and the DNS resolvers do not log queries from users. Any inquiries related to the operation of this DNS seed can be sent to <noc@wiz.biz>.
Here is a rough diagram of the `seed.bitcoin.wiz.biz` DNS seed architecture:

Every `return false` is preceeded by a detailed debug log message to
explain that a disconnect or misbehavior happened. Logging another
generic "FAILED" message seems redundant.
Also, the size of the message and the message type has already been
logged and is thus redundant as well.
Finally, claiming that message processing FAILED seems odd, because the
message was fully processed to the point where it was concluded that the
peer should be either disconnected or marked as misbehaving.

ff8c430c65 [test] test disconnect for filterclear (gzhao408)
1c6b787e03 [netprocessing] disconnect node that sends filterclear (gzhao408)
Pull request description:
Nodes that don't have bloomfilters turned on (i.e. no `NODE_BLOOM` service) should disconnect peers that send them `filterclear` P2P messages.
Non-bloomfilter nodes already disconnect peers for [`filteradd` and `filterload`](19e919217e/src/net_processing.cpp (L2218)), but #8709 removed `filterclear` so it could be used to reset tx relay. This isn't needed now because using `feefilter` message is much better for this purpose (See #19204).
Also refactors existing disconnect logic for `filteradd` and `filterload` into respective message handlers and removes banning for them.

The utility is primarily useful to dereference pointer types, which are
known to be not null at that time.
For example, the ArgsManager is known to exist when the wallets are
started. Instead of silently relying on that assumption, Assert can be
used to abort the program and avoid UB should the assumption ever be
violated.
-Increasing the banscore and/or banning is too harsh,
just disconnecting is enough.
-Return true from ProcessMessage because we already log
receipt of filterclear and disconnect.
-nodes not serving bloomfilters should disconnect peers
that send filterclear, just like filteradd and filterload
-nodes that want to enable/disable txrelay should use
feefilter

This replaces the current benchmarking framework with nanobench [1], an
MIT licensed single-header benchmarking library, of which I am the
autor. This has in my opinion several advantages, especially on Linux:
* fast: Running all benchmarks takes ~6 seconds instead of 4m13s on
an Intel i7-8700 CPU @ 3.20GHz.
* accurate: I ran e.g. the benchmark for SipHash_32b 10 times and
calculate standard deviation / mean = coefficient of variation:
* 0.57% CV for old benchmarking framework
* 0.20% CV for nanobench
So the benchmark results with nanobench seem to vary less than with
the old framework.
* It automatically determines runtime based on clock precision, no need
to specify number of evaluations.
* measure instructions, cycles, branches, instructions per cycle,
branch misses (only Linux, when performance counters are available)
* output in markdown table format.
* Warn about unstable environment (frequency scaling, turbo, ...)
* For better profiling, it is possible to set the environment variable
NANOBENCH_ENDLESS to force endless running of a particular benchmark
without the need to recompile. This makes it to e.g. run "perf top"
and look at hotspots.
Here is an example copy & pasted from the terminal output:

* Adds support for asymptotes
This adds support to calculate asymptotic complexity of a benchmark.
This is similar to #17375, but currently only one asymptote is
supported, and I have added support in the benchmark `ComplexMemPool`
as an example.
Usage is e.g. like this:
```
./bench_bitcoin -filter=ComplexMemPool -asymptote=25,50,100,200,400,600,800
```
This runs the benchmark `ComplexMemPool` several times but with
different complexityN settings. The benchmark can extract that number
and use it accordingly. Here, it's used for `childTxs`. The output is
this:
| complexityN | ns/op | op/s | err% | ins/op | cyc/op | IPC | total | benchmark

| 0.0129823 | 114.4% | O(log n)
| 0.0815055 | 133.8% | O(1)
The best fitting curve is O(n^2), so the algorithm seems to scale
quadratic with `childTxs` in the range 25 to 800.
fadf6bd04f refactor: Remove unused request.fHelp (MarcoFalke)
fad889cbf0 wallet: Make RPC help compile-time static (MarcoFalke)
Pull request description:
Currently calling `help` on a wallet RPC method will either return `help: unknown command: getnewaddress` or the actual help. This runtime dependency of the help is a bug that complicates any tool that relies on documentation. Also, the code that enables the bug is overly complicated and confusing.
The fix is split into two commits:
* First, a commit that can be reviewed with the `--color-moved=dimmed-zebra` option and tested with the included test.
* Second, a commit that removes the complicated and confusing code.

Pull request description:
A straightforward and hopefully uncontroversial refactor to improve consistency.
- Move the decision whether to translate an individual error message to where it is defined. This simplifies call sites: no more `InitError(Untranslated(SomeFunction(...)))`.
- Make all functions in `util/error.h` consistently return a `bilingual_str`. We've decided to use this as error message type so let's roll with it.
This has no functional changes: no messages are changed, no new translation messages are defined.
Also make a function static that can be static.

8fe63e5654 Increase robustness against UB. Thanks to elichai2 who noted that the literal '1' is a signed integer, and that shifting a signed 32-bit integer by 31 bits causes an overflow and yields undefined behaviour. While 'scalar_low_impl''s 'secp256k1_scalar_cadd_bit' is only used for testing purposes and currently the 'bit' parameter is only 0 or 1, it is better to avoid undefined behaviour in case the used domain of 'secp256k1_scalar_cadd_bit' expands.

- Move the decision whether to translate an error message to where it is
defined. This simplifies call sites: no more `InitError(Untranslated(...))`.
- Make all functions in `util/error.h` consistently return a
`bilingual_str`. We've decided to use this as error message type so
let's roll with it.
This has no functional changes: no messages are changed, no new
translation messages are defined.
b00266fe0c refactor: replace pointers by references within tx_verify.{h,cpp} (Sebastian Falbesoner)
Pull request description:
This PR gets rid of another unnecessary use of raw pointers, similar to PR #19053 (see also issue #19062 where useful commands for finding potential candidates are listed) but in the tx verification module.
For the functions `CalculateSequenceLocks()` and `SequenceLocks()`, the `prevHeights` vector parameter type is changed to be passed as a reference. Note that there were no checks for null pointers -- if one would pass `nullptr` to one of the functions, the following line would immediately lead to a crash:

34645c4dd0 Test txinwitness is accessible on coinbase vin (Rod Vagg)
3e4421070a Expose txinwitness for coinbase in JSON form (Rod Vagg)
Pull request description:
## Rationale
The CLI can provide you with everything about transactions and blocks that you need to reconstruct the block structure and raw block itself **except** for the witness commitment nonce which is stored in the `scriptWitness` of the coinbase and is not printed. You could manually parse the raw `"hex"` fields for transactions if you really wanted to, but this seems to defeat the point of having a JSONification of the raw block/transaction data.
Without the nonce you can't:
1. calculate and validate the witness commitment yourself, you can generate the witness tx merkle root but you don't have the nonce to combine it with
2. reconstruct the raw block form because you don't have `scriptWitness` stack associated with the coinbase (although you know how big it will be and can guess the common case of `[0x000...000]`)
I'm building some archiving tooling for block data and being able to do a validated two-way conversion is very helpful.
## What
This PR simply makes the `txinwitness` field not dependent on whether we are working with the coinbase or not. So you get it for the coinbase as well as the rest.
## Examples
Common case of a `[0x000...000]` nonce: 00000000000000000000140a7289f3aada855dfd23b0bb13bb5502b0ca60cdd7

"vin": [

],

],
"sequence": 4294967295
}
],
...
```
## Alternatives
This field could be renamed for the coinbase, `"witnessnonce"` perhaps. It could also be omitted when null/zero (`0x000...000`).
## Tests
This didn't break any tests and I couldn't find an obvious way to include a test for this. If this is desired I'd apreicate some pointers.
