63d6ad7c89cd682f6e779968c4861ea085058356 Move BlockMerkleBranch back to merkle.{h,cpp} (Sjors Provoost)
Pull request description:
The new `BlockTemplate` interface introduced in #30440 allows for a more efficient way for a miner to submit the block solution. Instead of having the send the full block, it only needs to provide the nonce, timestamp, version fields and coinbase transaction.
This PR introduces `submitSolution()` for that. It's currently unused.
#29432 and https://github.com/Sjors/bitcoin/pull/48 use it to process the Stratum v2 message [SubmitSolution](https://github.com/stratum-mining/sv2-spec/blob/main/07-Template-Distribution-Protocol.md#77-submitsolution-client---server). The method should be sufficiently generic to work with alternative mining protocols (none exist that I'm aware off).
This PR also introduces `getCoinbaseMerklePath()`, which is needed in Stratum v2 to construct the `merkle_path` field of the `NewTemplate` message (see [spec](https://github.com/stratum-mining/sv2-spec/blob/main/07-Template-Distribution-Protocol.md#72-newtemplate-server---client)). The coinbase merkle path is also used in Stratum "v1", see e.g. https://bitcoin.stackexchange.com/questions/109820/questions-on-merkle-root-hashing-for-stratum-pools
This last function uses `BlockMerkleBranch` which was moved to the test code in #13191. The reason back then for moving it was that it was no longer used. This PR moves it back.
This PR does not change behaviour since both methods are unused.

Instead of having a single NodeContext::shutdown member that is used both to
request shutdowns and check if they have been requested, use separate members
for each. Benefits of this change:
1. Should make code a little clearer and easier to search because it is easier
to see which parts of code are triggering shutdowns and which parts are just
checking to see if they were triggered.
2. Makes it possible for init.cpp to specify additional code to run when a
shutdown is requested, like signalling the m_tip_block_cv condition variable.
Motivation for this change was to remove hacky NodeContext argument and
m_tip_block_cv access from the StopRPC function, so StopRPC can just be
concerned with RPC functionality, not other node functionality.
This is not strictly required, but all places using m_tip_block_cv
(except shutdown) already take the lock. The annotation makes it easier
to catch potential deadlocks before review.
Adding the missing lock to the shutdown sequence is a bugfix.
An alternative would be to take the lock and release it before
notifying, see

Pull request description:
Continues #30005. Closes #17012..
This PR adds PCP (Port Control Protocol) from [RFC6887](https://datatracker.ietf.org/doc/html/rfc6887). This adds, in addition to the existing IPv4 port mapping (which now uses PCP, with fallback to NAT-PMP), support for IPv6 pinholing-that is, opening a port on the firewall to make it reachable.
PCP, like NAT-PMP is a simple UDP-based protocol, and the implementation is self-contained, so this gets rid of lthe libnatpnp dependency without adding a new one. It should otherwise be a drop-in replacement. NAT-PMP fallback is implemented so this will not make router support worse.
For now it is disabled by default, though in the future (not in this PR) we could consider enable it by default to increase the number of connectable nodes without adding significant attack surface.
To test:
```bash
bitcoind -regtest -natpmp=1 -debug=net
```
(most of the changes in this PR are, ironically, removing the libnatpmp dependency and associated build system and build docs)

Pull request description:
This continues the work in #30200 so that a future Stratum v2 Template Provider (see #29432) can avoid accessing node internals. It needs to know when a new block arrives in order to push new templates to connected clients.
`waitTipChanged()` uses a new kernel notification `notifications().m_tip_block_mutex`, which this PR also introduces (a previous version used `g_best_block`).
In order to ensure the new method works as intended, the `waitfornewblock`, `waitforblock` and `waitforblockheight` RPC methods are refactored to use it. This allows removing `RPCNotifyBlockChange`.
There's a commit to add (direct) tests for the methods that are about to be refactored:
- `waitfornewblock` was already implicitly tested by `feature_shutdown.py`.
- `waitforblockheight` by `feature_coinstatsindex.py` and `example_test.py`
This PR renames `getTipHash()` to `getTip()` and returns a `BlockRef` (renamed from `BlockKey`) so that callers can use either the height or hash.
The later commits make trivial improvements to the `waitfor*` RPC calls (not needed for this PR).
The `waitTipChanged()` method could probably also be used for the longpoll functionality in `getblocktemplate`, but I'm a bit reluctant to touch that.
`RPCServer::OnStarted` no longer does anything and `RPCServer::OnStopped` merely prints a log statement. They were added in #5711 as a refactor. This PR drops them entirely.
Finally `g_best_block` is also dropped.

Also signal m_tip_block_cv when StopRPC is called, for

StopRPC instead of OnRPCStopped() because the latter
is deleted in a later commit.

An external program that uses the Mining interface may need quick access to some information in the block template, while it can wait a bit longer for the full raw transaction data.
This would be the case for a Stratum v2 Template Provider which needs to send a [NewTemplate](https://github.com/stratum-mining/sv2-spec/blob/main/07-Template-Distribution-Protocol.md#72-newtemplate-server---client) message message (which doesn't include transactions) as quickly as possible. It does not include the serialized block transactions.

The thread handle is never used by the ChainstateManager, so move it out
and into the node context. Users of the kernel library now no longer
have to manually join the thread when destructing the ChainstateManager.

Pull request description:
Increase the maximum number of logging categories from 32 to 64.
We're currently using 29 of the 32 available logging categories (there are only 3 remaining). It would be good to increase the limit soon; the fourth PR to be merged that adds a new logging category will be blocked until something like this is done.
This PR also adds a `TEST` category that uses the new range (`1ULL << 63`) in case there's a hidden assumption somewhere that the `BCLog::LogFlags` type is 32 bits. (Also added a test for this test category.) It also provides an example showing that the expression must be `1ULL << <shift>` for shift value 31 and beyond.

- `-assumevalid` will raise an error when input contains invalid hex characters, or when it is longer than 64 hex digits
- test: the optional RANDOM_CTX_SEED env var will now cause tests to abort when it contains invalid hex characters, or when it is longer than 64 hex digits
After this PR, the remaining work to remove `uint256S` completely is almost entirely mechanical and/or test related. I will open that PR once #30560 is merged because it builds on that.

Code review ACK 18d65d27726bf9fc7629b8e794047a10c9cf6156. Very nice change that cleans up the API, adds checking for invalid values, makes parsing of values more consistent, and adds test coverage.

1b41d45d462d856a9d0b44ae0039bbb2cd78407c wallet: bugfix: ensure atomicity in settings updates (ismaelsadeeq)
Pull request description:
This PR fixes#30620.
As outlined in the issue, creating two wallets with `load_on_startup=true` simultaneously results in only one wallet being added to the startup file.
The current issue arises because the wallet settings update process involves:
1. Obtaining the settings value while acquiring the settings lock.
2. Modifying the settings value.
3. Overwriting the settings value while acquiring the settings lock again.
This sequence is not thread-safe. Different threads could modify the same base value simultaneously, overwriting data from other workers without realizing it.
The PR attempts to fix this by modifying the chain interface's `updateRwSetting` method to accept a function that will be called with the settings reference. This function will either update or delete the setting and return an enum indicating whether the settings need to be overwritten in this or not.
Additionally, this PR introduces two new methods to the chain interface:
- `overwriteRwSetting`: This method replaces the setting with a new value.
Used in `VerifyWallets`
- `deleteRwSettings`: This method completely erases a specified setting.
This method is currently used only in `overwriteRwSetting`.
These changes ensure that updates are race-free across all clients.

- Settings updates were not thread-safe, as they were executed in
three separate steps:
1) Obtain settings value while acquiring the settings lock.
2) Modify settings value.
3) Overwrite settings value while acquiring the settings lock.
This approach allowed concurrent threads to modify the same base value
simultaneously, leading to data loss. When this occurred, the final
settings state would only reflect the changes from the last thread
that completed the operation, overwriting updates from other threads.
Fix this by making the settings update operation atomic.
- Add test coverage for this behavior.

Removes dependency on unsafe and deprecated uint256S.
This makes parsing more strict, by returning an error
when the input contains non-hex characters, or when it
contains more than 64 hex digits.
Also make feature_assumevalid.py more robust by using CBlock.hash
which is guaranteed to be 64 characters long, as opposed to the
variable-length hex(CBlock.sha256)

Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/30514 which has more context and shows how the issue can be reproduced. Since the value in question is removed, there is no test to add to reproduce anything.
This is an alternative approach to #30516 with much of the [code being suggested there](https://github.com/bitcoin/bitcoin/pull/30516#discussion_r1689146902).

Pull request description:
C++20 introduces [`std::ranges::views::reverse`](https://en.cppreference.com/w/cpp/ranges/reverse_view), which allows us to drop our own `reverse_iterator.h` implementation and also makes it easier to chain views (even though I think we currently don't use this).

fa7f7ac040a9467c307b20e77dc47c87d7377ded Return XOR AutoFile from BlockManager::Open*File() (MarcoFalke)
Pull request description:
Currently the *.dat files in the blocksdir store the data received from remote peers as-is. This may be problematic when a program other than Bitcoin Core tries to interpret them by accident. For example, an anti-virus program or other program may scan them and move them into quarantine, or delete them, or corrupt them. This may cause Bitcoin Core to fail a reorg, or fail to reply to block requests (via P2P, RPC, REST, ...).
Fix this, similar to https://github.com/bitcoin/bitcoin/pull/6650, by rolling a random XOR pattern over the dat files when writing or reading them.
Obviously this can only protect against programs that accidentally and unintentionally are trying to mess with the dat files. Any program that intentionally wants to mess with the dat files can still trivially do so.
The XOR pattern is only applied when the blocksdir is freshly created, and there is an option to disable it (on creation), so that people can disable it, if needed.
