af9ea55a72c94678b343f5dd98dc78f3a3ac58cb Use LockAssertion utility class instead of AssertLockHeld() (Hennadii Stepanov)
Pull request description:
On the way of transit from `RecursiveMutex` to `Mutex` (see #19303) it is crucial to have run-time `AssertLockHeld()` assertion that does _not_ hide compile-time Clang Thread Safety Analysis warnings.
On master (65e4ecabd5b4252154640c7bac38c92a3f3a7018) using `AssertLockHeld()` could hide Clang Thread Safety Analysis warnings, e.g., with the following patch applied:
```diff

+++ b/src/txmempool.h
@@ -607,7 +607,7 @@ public:

```
Clang compiles the code without any thread safety warnings.
See "Add missed thread safety annotations" commit for the actual thread safety warnings that are fixed in this PR.

fa93bc14c7411a108dd024d391344fabf0f76369 rpc: Remove unused return type from appendCommand (MarcoFalke)
Pull request description:
This is split out from #18531 to just touch the RPC methods in misc. 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

6d1f51343cf11b07cd401fbd0c5bc3603e185a0e [rpc] fundrawtransaction, walletcreatefundedpsbt lock manually selected coins (Sjors Provoost)
Pull request description:
When using `fundrawtransaction` and `walletcreatefundedpsbt` with `lockUnspents`, it would only lock automatically selected coins, not manually selected coins. That doesn't make much sense to me if the goal is to prevent accidentally double-spending yourself before you broadcast a transaction.
Note that when creating a transaction, manually selected coins are automatic "unlocked" (or more accurately: the lock is ignored). Earlier versions of this PR introduced an error when a locked coin is manually selected, but this idea was abandoned after some discussion. An application that uses this RPC should either rely on automatic coin selection (with `lockUnspents`) or handle lock concurrency itself with manual coin selection. In particular it needs to make sure to avoid/pause calls with automatic coin selection between calling `lockunspent` and the subsequent spending RPC.
See #7518 for historical background.

The new NodeContext::wallet_client pointer will also be needed to eliminate global wallet variables like ::vpwallets in #19101, because createWallet(), loadWallet(), getWallets(), etc methods called by the GUI need a way to get a reference to the list of open wallets if it is no longer a global variable.

Pull request description:
Fixes a bug introduced in #19614
The LevelDB-specific fdatasync check was only using `AC_SUBST`, which works for Makefiles, but doesn't define anything for C++. Furthermore, the #define is typically 0 or 1, never undefined.
This fixes both issues by defining it and checking its value instead of whether it is merely defined.

Pull request description:
Document differences in `bitcoind` and `bitcoin-qt` locale handling.
Since this seems to be the root cause to the locale dependency issues we've seen over the years I thought it was worth documenting :)
Note that 1.) `QLocale` (used by Qt), 2.) C locale (used by locale-sensitive C standard library functions/POSIX functions and some parts of the C++ standard library such as `std::to_string`) and 3.) C++ locale (used by the C++ input/output library) are three separate things. This comment is about the perhaps surprising interference with the C locale (2) that takes place as part of the Qt initialization.

aba03359a6e62a376ae44914f609f82a1556fc89 [net processing] Remove CNodeState.name (John Newbery)
Pull request description:
We currently have two structures for per-peer data:
- `CNode` in net, which should just contain connection layer data (eg socket, send/recv buffers, etc), but currently also contains some application layer data (eg tx/block inventory).
- `CNodeState` in net processing, which contains p2p application layer data, but requires cs_main to be locked for access.
This PR adds a third struct `Peer`, which is for p2p application layer data, and doesn't require cs_main. Eventually all application layer data from `CNode` should be moved to `Peer`, and any data that doesn't strictly require cs_main should be moved from `CNodeState` to `Peer` (probably all of `CNodeState` eventually).
`Peer` objects are stored as shared pointers in a net processing global map `g_peer_map`, which is protected by `g_peer_mutex`. To use a `Peer` object, `g_peer_mutex` is locked, a copy of the shared pointer is taken, and the lock is released. Individual members of `Peer` are protected by different mutexes that guard related data. The lifetime of the `Peer` object is managed by the shared_ptr refcount.
This PR adds the `Peer` object and moves the misbehaving data from `CNodeState` to `Peer`. This allows us to immediately remove 15 `LOCK(cs_main)` instances.
For more motivation see #19398

Pull request description:
This micro-PR gets rid of base58 function interfaces that are redundant in terms of c-string / std::string variants; the c-string interface for `DecodeBase58Check` is completely unused outside the base58 module, while the c-string interface for `DecodeBase58` is only used in unit tests, where an implicit conversion to std::string is not problematic.

Comparing two empty `CChain`s is currently undefined behaviour, and resulted in false assertion failures when comparing identical empty `CChain`s in local testing.
Let's just remove this comparison operator since it doesn't seem to be used anywhere.

ACK b6dcc6d74186eee15eda2cb6e8a7ab5b5b4a05f8. I don't think there are any other obvious examples in the GUI where "block height" should replace "number of blocks" except for translations.

Add WalletClient interface so node interface is cleaner and don't need
wallet-specific methods.
The new NodeContext::wallet_client pointer will also be needed to eliminate
global wallet variables like ::vpwallets, because createWallet(), loadWallet(),
getWallets(), etc methods called by the GUI need a way to get a reference to
the list of open wallets if it is no longer a global variable.
Also tweaks splash screen registration for load wallet events to be delayed
until after wallet client is created.
Add AppInitInterfaces function so wallet chain and chain client interfaces are
created earlier during initialization. This is needed in the next commit to
allow the gui splash screen to be able to register for wallet events through a
dedicated WalletClient interface instead managing wallets indirectly through
the Node interface. This only works if the wallet client interface is created
before the splash screen needs to use it.
a99a3c0bd6d5476503c015e23be569295fdd190c rpc: Validate provided keys for query_options parameter in listunspent (pasta)
Pull request description:
At Dash, one of our developers was working with the `listunspent` RPC command, but instead of saying "minimumAmount" he said "minimmumAmount" as such the RPC wasn't working as expected.
In https://github.com/dashpay/dash/pull/3507 we implemented a check so that `listunspent` returns an error if an unrecognized option is given. I figured I might as well adapt the code and throw up a PR here.
Cheers!

This is needed to allow bitcoin-gui to connect to existing node process with
-ipcconnect instead of spawning a new process. It's possible to spawn a new
bitcoin-node process without knowing the current data dir or network, but
connecting to an existing bitcoin-node requires knowing the datadir and network
first.
No change in behavior. Replacing references with pointers allows Node interface
creation to be delayed until later during gui startup next commit to support
implementing -ipcconnect option
Change gui code to use gArgs, Params() functions directly instead of going
through interfaces::Node.
Remotely accessing bitcoin-node ArgsManager from bitcoin-gui works fine in
https://github.com/bitcoin/bitcoin/pull/10102, when bitcoin-gui spawns a new
bitcoin-node process and controls its startup, but for bitcoin-gui to support
-ipcconnect option in https://github.com/bitcoin/bitcoin/pull/19461 and connect
to an existing bitcoin-node process, it needs ability to parse arguments itself
before connecting out.
This change also simplifies https://github.com/bitcoin/bitcoin/pull/10102 a
bit, by making the bitcoin-gui -> bitcoin-node startup sequence more similar to
the bitcoin-node -> bitcoin-wallet startup sequence where the parent process
parses arguments and passes them to the child process instead of the parent
process using the child process to parse arguments.

2bc207190e6f1818b04c9336f6e0d625b2a2a0ba util: make EncodeBase32 consume Spans (Sebastian Falbesoner)
Pull request description:
To simplify the interface of the Base32/Base64 encoding functions for raw data, this PR changes them from taking two arguments (pointer and length) to just one Span. Most calls to `EncodeBase64` pass data from `CDataStream` instances, which unfortunately internally work with `char*` pointers rather than `unsigned char*`, but thanks to the recently introduced `MakeUCharSpan` helper, converting them is quite easy.

fa40017706e08b4de111e8e57aabeced60881a57 init: Pass reference to ArgsManager around instead of relying on global (MarcoFalke)
Pull request description:
The gArgs global has several issues:
* gArgs is used by each process (bitcoind, bitcoin-qt, bitcoin-wallet, bitcoin-cli, bitcoin-tx, ...), but it is hard to determine which arguments are actually used by each process. For example arguments that have never been registered, but are still used, will always return the fallback value.
* Tests may run several sub-tests, which need different settings. So globals will have to be overwritten, but that is fragile on its own: e.g. https://github.com/bitcoin/bitcoin/pull/19704#issuecomment-678259092 or #19511
The goal is to remove gArgs, but as a first step in that direction this pull will change gArgs in init to use a passed-in reference instead.

fanquake:
ACK fa9d5902f7d72e8cce105dd1b1f5a1062e304b10 - I'm not as familiar with the settings & argument handling code, but this make sense, and is a step in the right direction towards a reduction in the usage of globals. Not a huge fan of the clang-formatting in the scripted diff.
