This module is going to be responsible for managing everything related
to transaction download, including txrequest, orphan transactions and
package relay. It will be responsible for managing usage of the
TxOrphanage and instructing PeerManager:
- what tx or package-related messages to send to which peer
- whether a tx or package-related message is allowed or useful
- what transactions are available to try accepting to mempool
Future commits will consolidate the interface and re-delegate
interactions from PeerManager to TxDownloadManager.
9bb92c0e7f util: Remove RandAddSeedPerfmon (Hodlinator)
Pull request description:
`RegQueryValueExA(HKEY_PERFORMANCE_DATA, ...)` sometimes hangs *bitcoind.exe* on Windows during startup, at least on CI.
We have other sources of entropy to seed randomness with on Windows, so should be alright removing this. Might resurrect if less drastic fix is found.
Hopefully sufficient to fix#30390.
CI debugged with temporary Windows stack trace dumping + Symbols in #30956.

Pull request description:
The question mark is interpreted as a wildcard for any single character in Zsh (see https://www.techrepublic.com/article/globbing-wildcard-characters-with-zsh), so `bench_bitcoin -?` will not show the help message on systems using Zsh, such as macOS.
Since `-h` provides equivalent help functionality (as defined in https://github.com/bitcoin/bitcoin/blob/master/src/common/args.cpp#L684-L693), the `benchmarking.md` documentation has been updated to ensure compatibility with macOS.

e31bfb26c2 refactor: Remove unrealistic simulation state (Lőrinc)
Pull request description:
While reviewing [the removal of the unreachable combinations from the Coin cache logic](https://github.com/bitcoin/bitcoin/pull/30673#discussion_r1721727681), we've noticed that the related tests often [reflect impossible states](https://github.com/bitcoin/bitcoin/pull/30673/files#r1740154464).
Browsing the Coin cache refactoring history revealed that migrating `bool GetCoin` to `optional<Coin> GetCoin` was [already proposed a few times before](https://github.com/bitcoin/bitcoin/pull/18746#issuecomment-842393167).
This refactor makes certain invalid states impossible, reducing the possibility of errors and making the code easier to understand. This will let us remove test code that exercises the impossible states as well.
The PR is done in multiple small steps, first swapping the new `optional` return value, slowly strangling out the usages of the return parameter, followed by the removal of the parameter.
Most of the invalid test states were still kept, except for https://github.com/bitcoin/bitcoin/pull/30673/files#r1748087322, where the new design prohibits invalid usage and https://github.com/bitcoin/bitcoin/pull/30673/files#r1749350258 was just marked with a TODO, will be removed in a follow-up PR.

Pull request description:
Last step in a chain of PRs (#26836, #28894, #28987, #29403).
#### Detailed Description:
The current wallet migration process performs only individual db writes. Accessing disk to
delete all legacy records, clone and clean each address book entry for every created wallet,
create each new descriptor (with their corresponding master key, caches and key pool), and
also clone and delete each transaction that requires to be transferred to a different wallet.
This work consolidates all individual disk writes into two batch operations. One for the descriptors
creation from the legacy data and a second one for the execution of the migration process itself.
Efficiently dumping all the information to disk at once atomically at the end of each process.
This represent a speed up and also a consistency improvement. During migration, we either
want to succeed or fail. No other outcomes should be accepted. We should never leave a
partially migrated wallet on disk and request the user to manually restore the previous wallet from
a backup (at least not if we can avoid it).
Since the speedup depends on the storage device, benchmark results can vary significantly.
Locally, I have seen a 15% speedup on a USB 3.2 pendrive.
#### Note for Testers:
The first commit introduces a benchmark for the migration process. This one can be
cherry-picked on top of master to compare results pre and post changes.
Please note that the benchmark setup may take some time (~70 seconds here) due to the absence
of a batching mechanism for the address generation process (`GetNewDestination()` calls).

fa5126adcb fees: Pin "version that wrote" to 0 (MarcoFalke)
Pull request description:
Coupling the fees serialization with CLIENT_VERSION is problematic, because:
* `CLIENT_VERSION` may change, even though the serialization format does not change. This is harmless, but still confusing.
* If a serialization format change was backported (unlikely), it may lead to incorrect results.
* `CLIENT_VERSION` is changed at a different time during the release process than any serialization format change. This is harmless for releases of Bitcoin Core, but may be confusing when using the development branch.
* It is harder to reason about a global `CLIENT_VERSION` when changing the format, than to reason about a versioning local to the module.
Fix all issues by pinning the current version number in the module locally. In the future it can then be modified locally to the module, if needed.

cd0edf26c0 tracing: cast block_connected duration to nanoseconds (0xb10c)
Pull request description:
When the `validation:block_connected` tracepoint was introduced in 8f37f5c2a5, the connect block duration was passed in microseconds `µs`. By starting to use steady clock in fabf1cdb20 this changed to nanoseconds `ns`. As the test only checked if the duration value is `> 0` as a plausibility check, this went unnoticed. This was detected this when setting up monitoring for block validation time as part of the Great Consensus Cleanup Revival discussion.
This change casts the duration explicitly to nanoseconds, updates the documentation, and adds a check for an upper bound to the tracepoint interface tests. The upper bound is quite lax as mining the block takes much longer than connecting the empty test block. It's however able to detect a duration passed in an incorrect unit (1000x off).
A previous version of this PR casted the duration to microseconds `µs` - however, as the last three major releases have had the duration as nanoseconds (and this went unnoticed), we assume that this is the API now and changeing it back to microseconds would break the API again.

ccd10fdb97 build: Add missing USDT header dependency to kernel (Cory Fields)
Pull request description:
Noticed while testing a branch that replaces `boost::multi_index` with a custom replacement.
Currently depends builds pick up usdt and boost from the same path, and because boost always exists, the usdt path is implicitly included. So without boost, USDT isn't found.
An alternative to this would be to disable USDT for the kernel. I'd be open to either approach.

5901cf7100 clusterlin: abstract out DepGraph::GetReduced{Parents,Children} (Pieter Wuille)
Pull request description:
Part of cluster mempool: #30289
This adds:
* `DepGraph::AddDependencies` to add 0 or more dependencies to a single transaction at once (identical to calling `DepGraph::AddDependency` once for each, but more efficient).
* `DepGraph::RemoveTransactions` to remove 0 or more transactions from a depgraph.
* `DepGraph::GetReducedParents` (and `DepGraph::GetReducedChildren`) to get the (reduced) direct parents and children of a transaction in a depgraph.
After which, the `Cluster` type is removed.
This is the result of fleshing out the design for the "intermediate layer" ("TxGraph", no PR yet) between the cluster linearization layer and the mempool layer. My earlier thinking was that TxGraph would store `Cluster` objects (vectors of pairs of `FeeFrac`s and sets of parents), and convert them to `DepGraph` on the fly whenever needed. However, after more consideration, it seems better to have TxGraph store `DepGraph` objects, and manipulate them directly without constantly re-creating them. This requires `DepGraph` to have some additional functionality.
The bulk of the complexity here is the addition of `DepGraph::RemoveTransactions`, which leaves the remaining transactions' positions within the `DepGraph` untouched (we want existing identifiers to remain valid), so this implies that graphs can now have "holes" (positions that are unused, but followed by positions that are used). To enable that, an extension of the fuzz/test serialization format `DepGraphFormatter` is included to deal with such holes.

The chainstate caches are currently re-balanced on startup
even in the non-assumeutxo case, leading to the database being
needlessly re-opened and its cache re-allocated.
Similar to `InitCoinsCache` and `m_coinstip_cache_size_bytes` the
`m_coinsdb_cache_size_bytes` should be set in `InitCoinsDB`.
Together with only conservatively setting the cache values when a
assumeutxo chainstate is present, this allows for skipping the cache
re-balance during initialization in the normal non-assumeutxo case.

63d6ad7c89 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.

33381ea530 scripted-diff: Modernize nLocalServices to m_local_services (Fabian Jahr)
Pull request description:
The type of the `nLocalServices` variable was changed to `std::atomic<ServiceFlags>` in #30807 and I suggested the variable name to get updated with a scripted diff along with it. It wasn't included in the PR but I am still suggesting to do it as a follow-up since I had already prepared the commit.

This combines the clusterlin_add_dependency and clusterlin_cluster_serialization
fuzz tests into a single clusterlin_depgraph_sim fuzz test. This tests starts
from an empty DepGraph and performs a arbitrary number of AddTransaction,
AddDependencies, and RemoveTransactions operations on it, and compares the
resulting state with a naive reimplementation.
This commits introduces support in DepGraph for the transaction positions to be
non-continuous. Specifically, it adds:
* DepGraph::RemoveTransactions which removes 0 or more positions from a DepGraph.
* DepGraph::Positions() to get a set of which positions are in use.
* DepGraph::PositionRange() to get the highest used position in a DepGraph + 1.
In addition, it extends the DepGraphFormatter format to support holes in a
compatible way (it serializes non-holey DepGraphs identically to the old code,
and deserializes them the same way)
This changes DepGraph::AddDependency into DepGraph::AddDependencies, which takes
in a single child, but a set of parent transactions, making them all dependencies
at once.
This is important for performance. N transactions can have O(N^2) parents combined,
so constructing a full DepGraph using just AddDependency (which is O(N) on its own)
could take O(N^3) time, while doing the same with AddDependencies (also O(N) on its
own) only takes O(N^2).
Notably, this matters for DepGraphFormatter::Unser, which goes from O(N^3) to O(N^2).

This does not change the serialization format.
It turns out that it is unnecessary to keep track of the order of transactions
in the so-far reconstructed DepGraph to decide how far from the end to insert
a new transaction.
This commit does not change the serialization format. Its purpose is making a
few changes already in order to reduce the diff size of the later commit that
introduces support for holes in DepGraph.
The previous approach was to immediately construct a transaction as soon as its
feerate was known in a preliminary position, and then undo that, and place it
in the correct position once the position information is known (such that a
deserialization error in between would not result in an inconsistent state).
The new approach is to delay the actual transaction creation until all its
information is known, avoiding the need to undo and redo. This requires a
different means of determining whether dependencies are redundant, but that has
the advantage that a later commit can apply all dependencies at once, reducing
the complexity of deserialization.
A fuzz test already relies on these operations, and a future commit will need
the same logic too. Therefore, abstract them out into proper member functions,
with proper testing.
This has been unused since #29648.
Noticed while running a newer version of clang-tidy (19.1.1):
```bash
[127/391][6.2s] /opt/homebrew/opt/llvm/bin/clang-tidy -p=build -quiet --config-file=/bitcoin/src/.clang-tidy /bitcoin/src/test/script_tests.cpp

It is bad, because it is both printed for non-GUI users and does not
convey additional information.

fee4cba484 gui: Fix proxy details display in Options Dialog (pablomartin4btc)
Pull request description:
Currently, setting up a proxy (whether SOCKS5 or Tor) with an IPv6 address works correctly via the command line or configuration file in both `bitcoind` and `bitcoin-qt` (also from the UI the ipv6 address gets saved properly in `settings.json`). However, the UI does not reflect this properly, which can create confusion. Since some ISPs and VPNs still experience issues with IPv6, users may mistakenly think there is a problem with Bitcoin Core, when in fact the proxy setup is functioning as expected.
So this PR ensures that the proxy IP is displayed correctly in the UI when using an IPv6 address.
No functionality impact; changes only affect UI display.

fa2b7d8d6b Remove redundant unterminated-logprintf tidy check (MarcoFalke)
bbbb2e43ee log: Enforce trailing newline, Remove redundant m_started_new_line (MarcoFalke)
Pull request description:
There are many problems around missing a trailing newline while logging:
* All log lines are currently terminated by a trailing newline. This means any runtime code trying to handle a "missing" newline is currently dead code.
* Leaving a line unterminated is racy and can cause content corruption by mixing log lines from different sources.
* It requires extra code like `m_started_new_line` to keep track of, which is annoying and pointless to maintain, because it is currently dead code, see https://github.com/bitcoin/bitcoin/pull/30386#discussion_r1684380835.
* It requires a standalone `unterminated-logprintf` clang-tidy plugin, which is unmaintained (no one updated it for the new log function names), probably harder to maintain than normal C++ code (because it requires clang AST matcher knowledge), brittle (it can fail to detect issues at any time, if it goes out-of-sync, or be explicitly disabled via `NOLINT`), and annoying for devs (it is slow and intricate to run locally and thus only effectively run on CI or via the CI scripts).
Fix all issues by enforcing the trailing newline in logs directly in the code. Then remove all the other stuff.
This refactor does not change behavior.

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
https://github.com/bitcoin/bitcoin/pull/30967#discussion_r1778899716
It should be obvious that a wait is not needed if the tip does not
match.
Also, remove a comment that the blockTip notification was only meant for
the "UI". (It is used by other stuff for a long time)

Pull request description:
The for loop around the chain loading logic in `init.cpp` allows users of the GUI to retry once on failure with reindexing without having to manually set the reindex flag on startup. However this current mechanism has problems:
* It is badly documented and has led to confusion among developers and bugs making it into master. Examples:
* https://github.com/bitcoin/bitcoin/pull/28830/files#r1598392660
* https://github.com/bitcoin/bitcoin/pull/30132#issuecomment-2120741121
* It can only ever iterate once, making the choice of a for loop questionable.
* With its large scope it is easy for re-entry bugs to sneak in. Example:
* https://github.com/bitcoin/bitcoin/pull/28830#discussion_r1601589963
Attempt to fix this by moving the bulk of the logic into a separate function and replacing the for loop with a simpler `if` statement.

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)
## TODO
- [x] Default gateway discovery on Linux / FreeBSD
- [x] Default gateway discovery on Windows
- [x] Default gateway discovery on MacOS
- [x] Either solve FreeBSD compile issue (probably upstream issue) or remove FreeBSD support
## Things to consider for follow-up PRs
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1658764974 avoid unreachable nets (not given to -onlynet=)
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1658949236 could announce an addr:port where we do not listen (no -bind)
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1684368824 could announce the wrong port because it uses GetListenPort()
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1679709347 if we requested one port but another was assigned, then which one to use in the renewal?
- https://github.com/bitcoin/bitcoin/pull/30043#discussion_r1772017020 Use `GetAdapterAddresses` to discover local addresses for Windows
