1dcba996d3 Coinbase receivedby rpcs release notes (Andrew Toth)
b5696750a9 Test including coinbase transactions in receivedby wallet rpcs (Andrew Toth)
bce20c34d6 Include coinbase transactions in receivedby wallet rpcs (Andrew Toth)
Pull request description:
The current `*receivedby*` RPCs filter out coinbase transactions. This doesn't seem correct since an output to your address in a coinbase transaction *is* receiving those coins.
This PR corrects this behaviour. Also, a new option `include_immature_coinbase` is added (default=`false`) that includes immature coinbase transactions when set to true.
However, since this is potentially a breaking change this PR introduces a hidden configuration option `-deprecatedrpc=exclude_coinbase`. This can be set to revert to previous behaviour. If no reports of broken workflow are received, then this option can be removed in a future release.
Fixes https://github.com/bitcoin/bitcoin/issues/14654.

35d928c632 rpc: deprecate fee fields from mempool entries (josibake)
Pull request description:
per #22682 , top level fee fields for mempool entries have been deprecated since 0.17 but are still returned. this PR properly deprecates them so that they are no longer returned unless `-deprecatedrpc=fees` is passed.
the first commit takes care of deprecation and also updates `test/functional/mempool_packages.py` to only use the `fees` object. the second commit adds a new functional test for `-deprecatedrpc=fees`
closes#22682
## questions for the reviewer
* `-deprecatedrpc=fees` made the most sense to me, but happy to change if there is a name that makes more sense
* #22682 seems to indicate that after some period of time, the fields will be removed all together. if we have a rough idea of when this will be, i can add a `TODO: fully remove in vXX` comment to `entryToJSON`
## testing
to get started on testing, compile, run the tests, and start your node with the deprecated rpcs flag:
```bash
./src/bitcoind -daemon -deprecatedrpc=fees
```
you should see entries with the deprecated fields like so:
```json
{
"<txid>": {
"fees": {
"base": 0.00000671,
"modified": 0.00000671,
"ancestor": 0.00000671,
"descendant": 0.00000671
},
"fee": 0.00000671,
"modifiedfee": 0.00000671,
"descendantfees": 671,
"ancestorfees": 671,
"vsize": 144,
"weight": 573,
...
},
```
you can also check `getmempoolentry` using any of the txid's from the output above.
next start the node without the deprecated flag, repeat the commands from above and verify that the deprecated fields are no longer present at the top level, but present in the "fees" object

1ed5681407 rpc: add missing scantxoutset examples (Sebastian Falbesoner)
Pull request description:
The scantxoutset RPC and its help text was at last improved in #16285, but it's still missing examples (see https://github.com/bitcoin/bitcoin/pull/16285#issuecomment-529313781).
~Note that the example descriptor used doesn't follow the developer guideline of using invalid bech32 addresses, as the RPC is not wallet-related and it's use-case is merely to look up state information (i.e. there is no danger of sending funds to a wrong address).~ For the sake of simplicity, the raw descriptor for an early coinbase payout address (block 9) is taken, i.e. it yields results even at an early stage of IBD. Happy to change that though if there are other suggestions.

29e983386b Fixes Bug in Transaction generation in ComplexMempool benchmark (Shorya)
Pull request description:
This fixes issues with `ComplexMempool` benchmark introduced in [#17292](https://github.com/bitcoin/bitcoin/pull/17292) , this stress test benchmarks performance of ancestor and descendant tracking of mempool graph algorithms on a complex Mempool.
This Benchmark first creates 100 base transactions and stores them in `available_coins` vector. `available_coins` is used for selecting ancestor transactions while creating 800 new transactions. For this a random transaction is picked from `available_coins` and some of its outputs are mapped to the inputs of the new transaction being created.
Now in case we exhaust all the outputs of an entry in `available_coins` then we need to remove it from `available_coins` before the next iteration of choosing a potential ancestor , it is now implemented with this patch.
As the index of the entry is randomly chosen from `available_coins` , In order to remove it from the vector , if index of the selected entry is not at the end of `available_coins` vector , it is swapped with the entry at the back of the vector , then the entry at the end of `available_coins` is popped out.
Earlier the code responsible for constructing outputs of the newly created transaction was inside the loop used for assigning ancestors to the transaction , which does some unnecessary work as it creates outputs of the transaction again and again , now it is moved out of the loop so outputs of the transaction are created just once before adding it to the final list of the transactions created. This one is a minor change to save some computation.
These changes have changed the `ComplexMempool` benchmark results on `bitcoin:master` as follows :
**Before**

| ns/op | op/s | err% | total | benchmark

0c85dc30e6 p2p: Don't use timestamps from inbound peers (Martin Zumsande)
Pull request description:
`GetAdjustedTime()` (used e.g. in validation and addrman) returns a time with an offset that is influenced by timestamps that our peers have sent us in their version message.
Currently, timestamps from all peers are used for this.
However, I think that it would make sense to ignore the timedata samples from inbound peers, making it much harder for others to influence the Adjusted Time in a targeted way.
With the extra feeler connections (every 2 minutes on average) and extra block-relay-only connections (every 5 minutes on average) there are also now plenty of opportunities to gather a meaningful number of timedata samples from outbound peers.
There are some measures in place to prevent abuse: the `-maxtimeadjustment` parameter with a default of 70 minutes, warnings in cases of large deviations, only using the first 200 samples ([explanation](383d350bd5/src/timedata.cpp (L57-L72))), but I think that only using samples from outbound connections in the first place would be an additional safety measure that would make sense.
See also issue #4521 for further context and links: There have been several discussions in the past about replacing or abolishing the existing timedata system.

31ba1af74a Remove unused (and broken) functionality in SpanReader (Pieter Wuille)
Pull request description:
This removes the ability to set an offset in the `SpanReader::SpanReader` constructor, as the current code is broken since #23653. All call sites use `pos=0`, so it is actually unused. If future call sites need it, `SpanReader{a, b, c, d}` is equivalent to `SpanReader{a, b, c.subspan(d)}`.
It also removes the ability to deserialize from `SpanReader` directly from the constructor. This too is unused, and can be more idiomatically simulated using `(SpanReader{a, b, c} >> x >> y >> z)` instead of `SpanReader{a, b, c, x, y, z}`.

fa37e798b2 wallet: Replace confusing getAdjustedTime() with GetTime() (MarcoFalke)
Pull request description:
Setting `nTimeReceived` to the adjusted time has several issues:
* `m_best_block_time` is set to the "unadjusted" time, thus a comparison of the two times is like comparing apples to oranges. In the worst case this opens up an attack vector where remote peers can force a premature re-broadcast of wallet txs.
* The RPC documentation for `"timereceived"` doesn't mention that the network adjusted time is used, possibly confusing users when the time reported by RPC is off by a few seconds compared to their local timestamp.
Fix all issues by replacing the call with `GetTime()`. Also a style fix: Use non-narrowing integer conversion in the RPC method.

...by moving the try/catch out of LoadChainstate
I strongly recommend reviewing with the following git-diff flags:
--color-moved=dimmed_zebra --color-moved-ws=allow-indentation-change
...instead allow the caller to optionally pass in callbacks which are
triggered for certain events.
Behaviour change: The string "Verifying blocks..." was previously
printed for each chainstate in chainman which did not have an
effectively empty coinsview, now it will be printed once unconditionally
before we call VerifyLoadedChain.
This removes the ability to set an offset in the SpanReader constructor,
as the current code is broken. All call sites use pos=0, so it is actually
unused. If future call sites need it, SpanReader{a, b, c, d} is equivalent
to SpanReader{a, b, c.subspan(d)}.
It also removes the ability to deserialize from SpanReader directly from
the constructor. This too is unused, and can be more idiomatically
simulated using (SpanReader{a, b, c} >> x >> y >> z) instead of
SpanReader{a, b, c, x, y, z}.
This allows us to separate the initialization code from translations and
error reporting.
This change changes the caller semantics of LoadChainstate quite
drastically.
To see that this change doesn't change behaviour, observe that:
1. Prior to this change, LoadChainstate returned false only in the "bad
genesis block" failure case (by returning InitError()), indicating
that the caller should immediately bail. After this change, the
corresponding ERROR_BAD_GENESIS_BLOCK handler in src/init.cpp
maintains behavioue by also bailing immediately.
2. The failed_* temporary booleans were only used to break out of the
outer do/while(false) loop. They can therefore be safely removed.
I strongly recommend reviewing with the following git-diff flags:
--color-moved=dimmed_zebra --color-moved-ws=allow-indentation-change
[META] This commit is intended to be as close to a move-only commit as

Wallet RPCs that allow a rescan based on block-timestamp or block-height
need to sync with the active chain first, because the user might assume
the wallet is up-to-date with the latest block they got reported via a
blockchain RPC.
11daf6ceb1 More Span simplifications (Pieter Wuille)
568dd2f839 Replace MakeSpan helper with Span deduction guide (Pieter Wuille)
Pull request description:
C++17 supports [user-defined deduction guides](https://en.cppreference.com/w/cpp/language/class_template_argument_deduction), allowing class constructors to be invoked without specifying class template arguments. Instead, the code can contain rules to infer the template arguments from the constructor argument types.
This alleviates the need for the `MakeSpan` helper. Convert the existing MakeSpan rules into deduction rules for `Span` itself, and replace all invocations of `MakeSpan` with just `Span` ones.

456e350926 wallet: resolve ambiguity of two ScriptPubKey managers providing same script (S3RK)
Pull request description:
This PR fixes certain use-cases when **send-to-self** transactions are missing from `listtransactions` output.
1. When a receiving address is generated externally to the wallet
(e.g. same wallet running on two nodes, or by 3rd party from xpub)
2. When restoring backup with lost metadata, but keypool gap is not exceeded yet
When the block is connected or tx added to mempool we already mark used keys. This PR extends this logic to determine whether the destination is a receiving one and if yes add it to the address book with empty label.
Works both for legacy and descriptors wallets.
- For legacy it uses the internal flag from the keypool entry. Caveat: because we don't know which script type would be used we add all possible destinations for such keys.
- For descriptor wallets it uses internal flag for the script pub key manager. Caveat: it only works for active descriptors.

It is unclear what the goal of the helper is, as the caller already
knows the spend height before calling the helper.
Also, in case the coins view is corrupted, LookupBlockIndex will return
nullptr. Dereferencing a nullptr is UB.
Fix both issues by removing it. Also, add a sanity check, which aborts
if the coins view is corrupted.
fa551b3bdd Remove GetAdjustedTime from init.cpp (MarcoFalke)

Pull request description:
It seems confusing to call `GetAdjustedTime` there, because no offset could have been retrieved from the network at this point. Even if connman was started, `timedata` needs at least 5 peer connections to calculate an offset.
Fix the confusion by replacing `GetAdjustedTime` with `GetTime`, which does not change behavior.
Also:
* Replace magic number with `MAX_FUTURE_BLOCK_TIME` to clarify the context
* Add test, which passes both on current master and this pull request

This removes uncompiled code.
Can be checked by inserting `static_assert(STANDARD_LOCKTIME_VERIFY_FLAGS & LOCKTIME_MEDIAN_TIME_PAST)` and compiling or by reading the source code.
Even if the code was compiled, it would be unsafe to execute, since it is not allowed to include transactions that are locked until some time after the current MTP.
Also, rename the member to cause explicit merge conflicts in case there is a patch out there referencing the variable.

Pull request description:
Remove 2 circular dependencies: validation - txmempool and validation - policy/rbf - txmempool
Validation should depend on txmempool (e.g. `CChainstateManager` has a mempool and we often need to know what's in our mempool to validate transactions), but txmempool is a data structure that shouldn't really need to know about chain state.
- Changes `removeForReorg()` to be parameterized by a callable that returns true/false (i.e. whether the transaction should be removed due to being now immature or nonfinal) instead of a `CChainState`. The mempool really shouldn't need to know about coinbase maturity or lockpoints, it just needs to know which entries to remove.

- Actually generate an assumeutxo hash and display it
- Add nchaintx to output (necessary for use in chainparams entry)
- Add path of serialized UTXO file to output
No behavior change.
Parameterize removeForReorg using a CChain and callable that
encapsulates validation logic. The mempool shouldn't need to know a
bunch of details about coinbase maturity and lock finality. Instead,
just pass in a callable function that says true/false. Breaks circular
dependency by removing txmempool's dependency on validation.
Each entry's lockpoints are independent of one another, so there isn't
any reason to update lockpoints for entries that will be removed.
Separating the loops also allows us to move validation logic out and
leave lockpoints in txmempool.

As node operators are free to set their mempool policies however they
please, it's possible for package transaction(s) to already be in the
mempool. We definitely don't want to reject the entire package in that
case (as that could be a censorship vector).
We should still return the successful result to the caller, so add
another result type to MempoolAcceptResult.

f13a22a631 wallet: Call load handlers without cs_wallet locked (João Barbosa)
Pull request description:
Don't have `cs_wallet` locked while calling each `context.wallet_load_fns`. A load handler can always lock `cs_wallet` if needed.
The lock was added in 1c7e25db0c to satisfy TSAN. With 44c430ffac most of the code requiring the lock is in `CWallet::AttachChain`. A comment is added to warn about wallets_mutex and cs_wallet lock ordering.

This allows filters to be reconstructed when the best known block is
the Genesis block without needing to reindex.
It fixes Init errors seen in #23289.

Pull request description:
It is impossible to run the miner without a node (validation, chainstate, mempool, rpc, ...). Also, the module is in the node library. Thus, it should be moved to `src/node`.
Also, replace the `validation.h` include in the header with a forward-declaration.

d8ee8f3cd3 refactor: Make CWalletTx sync state type-safe (Russell Yanofsky)
Pull request description:
Current `CWalletTx` state representation makes it possible to set inconsistent states that won't be handled correctly by wallet sync code or serialized & deserialized back into the same form.
For example, it is possible to call `setConflicted` without setting a conflicting block hash, or `setConfirmed` with no transaction index. And it's possible update individual `m_confirm` and `fInMempool` data fields without setting an overall consistent state that can be serialized and handled correctly.
Fix this without changing behavior by using `std::variant`, instead of an enum and collection of fields, to represent sync state, so state tracking code is safer and more legible.
This is a first step to fixing state tracking bugs https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Transaction-Conflict-Tracking, by adding an extra margin of safety that can prevent new bugs from being introduced as existing bugs are fixed.

68e5aafde3 build: add `--enable-lto` configuration option (fanquake)
Pull request description:
It's been 5 years since using LTO was first suggested for use when building Bitcoin Core, and it's time to revisit it again. Compilers, and their LTO implementations, have matured, and Bitcoin Core has come a long way in terms of pruning dependencies which may have proved troublesome (i.e Boost previously had issues when using LTO). We'll have even less Boost code after moving to `std::filesystem` (#20744).
Experimenting with LTO came up on IRC last night:
> sipa: jamesob: i'm interested in knowing whether "-flto" and/or "-fdata-sections -ffunction-sections -Wl,--gc-sections" are possible/beneficial with our current compiler suite; what would be a good way to have your test infrastructure benchmark things?
So this PR just adds the bare minimum to make it easier to configure, compile and perform some bench-marking using `-flto`. This PR doesn't do anything depends wise, however if we decide this is what we want to do, I'll expand the changes here.
I had previously had a PR open (#18605) to perform link time garbage collection (`-ffunction-sections -fdata-sections` & `-Wl,--gc-sections`), however moving straight to using LTO would be preferable.
Note that our minimum required set of compilers, GCC 8.1 and Clang 7, all support the `-flto` option.
Related #18579.
Previous discussion: #10616, #14277.
Previous related PRs: #10800 (`-flto`), #16791 (ThinLTO).

574cc4271a refactor: remove RecursiveMutex cs_totalBytesRecv, use std::atomic instead (Sebastian Falbesoner)
Pull request description:
This PR is related to #19303 and gets rid of the following RecursiveMutex members in class `CConnman`:
* for `cs_totalBytesRecv`, protecting `nTotalBytesRecv`, `std::atomic` is used instead (the member is only increment at one and read at another place, so this is sufficient)
* for `m_addr_fetches_mutex`, protecting `m_addr_fetches`, a regular `Mutex` is used instead (there is no chance that within one critical section, another one is called)
* for `cs_vAddedNodes`, protecting `vAddedNodes`, a regular `Mutex` is used instead (there is no chance that within one critical section, another one is called)
Additionally, the PR takes the chance to rename all node vector members (vNodes, vAddedNodes) and its corresponding mutexes (cs_vNodes, cs_vAddedNodes) to match the coding guidelines via a scripted-diff.

fa3e0da06b policy: Treat taproot as always active (MarcoFalke)
Pull request description:
Now that taproot is active, it can be treated as if it was always active for policy for the next major release. This simplifies the code and changes two things:
* Importing `tr` descriptors can be done before the chain is fully synced. This is fine, because the wallet will already generate `tr` descriptors by default (regardless of the taproot status) after commit 47fe7445e7.
* Valid taproot spends won't be rejected from the mempool before taproot is active. This is strictly speaking a bugfix after commit 47fe7445e7, since the wallet may generate taproot spends before the chain is fully synced. For example, a slow node or a purposefully offline node. Currently, the wallet needs the mempool to account for change. See https://github.com/bitcoin/bitcoin/issues/11887.
A similar change was done for segwit v0 in https://github.com/bitcoin/bitcoin/pull/13120 .
This effectively reverts commit c5ec0367d7.

The RecursiveMutex m_added_nodes_mutex is used at three places:
- CConnman::GetAddedNodeInfo()
- CConnman::AddNode()
- CConnman::ThreadOpenConnections()
In each of the critical sections, only the the m_added_nodes member is
accessed (and in the last case, also m_addr_fetches), without any chance
that within one section another one is called. Hence, we can use an
ordinary Mutex instead of RecursiveMutex.
The RecursiveMutex m_addr_fetches_mutex is used at three places:
- CConnman::AddAddrFetch()
- CConnman::ProcessAddrFetch()
- CConnman::ThreadOpenConnections()
In each of the critical sections, only the the m_addr_fetches is accessed
(and in the last case, also vAddedNodes), without any chance that within
one section another one is called. Hence, we can use an ordinary Mutex
instead of RecursiveMutex.
The RecursiveMutex cs_totalBytesRecv is only used at two places: in
CConnman::RecordBytesRecv() to increment the nTotalBytesRecv member, and in
CConnman::GetTotalBytesRecv() to read it. For this simple use-case, we can
make the member std::atomic instead to achieve the same result.

lock
release each node from the copy

Addresses (partially) #16779 - no GUI change in this PR
Adds a LocateError function the bech32 library, which is then called by `validateaddress` RPC, (and then eventually from a GUI tool too, future work). I think modifying validateaddress is nicer than adding a separate RPC for this.
Includes tests.
Based on https://github.com/sipa/bech32/blob/master/ecc/javascript/bech32_ecc.js

Code review ACK 88cc481092 with caveat that I only checked the new `LocateErrors` code to try to verify it didn't have unsafe or unexpected operations or loop forever or crash. Did not try to verify behavior corresponds to the spec. In the worst case bugs here should just affect error messages not actual decoding of addresses so this seemed ok.

ee03c782ba wallet: Make GetOldestKeyPoolTime return nullopt for blank wallets (Hennadii Stepanov)
3e4f069d23 wallet, refactor: Make GetOldestKeyPoolTime return type std::optional (Hennadii Stepanov)
Pull request description:
The "keypoololdest" field in the `getwalletinfo` RPC response should be used for legacy wallets only.
Th current implementation (04437ee721) assumes that `CWallet::GetOldestKeyPoolTime()` always return `0` for descriptor wallets. This assumption is wrong for _blank_ descriptor wallets, when `m_spk_managers` is empty. As a result:
```
$ src/bitcoin-cli -signet -rpcwallet=211024-d-DPK getwalletinfo

25a581419d GUI/Options: Restore "S" accelerator for "Start on system login" option (Luke Dashjr)
Pull request description:
bitcoin-core/gui#416 changed the option assigned to accelerator key "S", but there's no rationale given.
Best to leave it alone, and give the new option a new accelerator key.
Since "R" is already taken for Reset, this shifts the new RPC server option to use "P" instead

`CConnman::SocketHandler()` does 3 things:
1. Check sockets for readiness
2. Process ready listening sockets
3. Process ready connected sockets
Split the processing (2. and 3.) into separate methods to make the code
easier to grasp.
Also, move the processing of listening sockets after the processing of
connected sockets to make it obvious that there is no dependency and
also explicitly release the snapshot before dealing with listening
sockets - it is only necessary for the connected sockets part.
They were needed to define the scope of `LOCK(cs_vNodes)` which was
removed in the previous commit. Re-indent in a separate commit to ease
review (use `--ignore-space-change`).
Create the snapshot of `CConnman::vNodes` to operate on earlier in
`CConnman::SocketHandler()`, before calling `CConnman::SocketEvents()`
and pass the `vNodes` copy from the snapshot to `SocketEvents()`.
This will keep the refcount of each node incremented during
`SocketEvents()` so that the `CNode` object is not destroyed before
`SocketEvents()` has finished.
Currently in `SocketEvents()` we only remember file descriptor numbers
(when not holding `CConnman::cs_vNodes`) which is safe, but we will
change this to remember pointers to `CNode::m_sock`.
The following pattern was duplicated in CConnman:
```cpp
lock
create a copy of vNodes, add a reference to each one
unlock
... use the copy ...
lock
release each node from the copy
unlock
```
Put that code in a RAII helper that reduces it to:
```cpp
create snapshot "snap"
... use the copy ...
// release happens when "snap" goes out of scope
```
