c5825d4b7fe9ae202ea3c74798f58cd3a920821d qa: Require `--exclude` for each excluded test (Hennadii Stepanov)
Pull request description:
This PR allows a long `--exclude ...` argument in the `test/functional/test_runner.py` invocation to be split across multiple lines, with optional per-line explanatory comments. I found this useful for the CI scripts in https://github.com/hebasto/bitcoin-core-nightly.

- We no longer enforce ancestor/descendant count limit
in both PreChecks and PackageMempoolChecks.
- This commit fixes the incorrect comment by just renaming
`PackageMempoolChecks` to `PackageRBFChecks`
- The method name is self explanatory now; hence no need
for a description comment.

d59b4cdb5772917ee13e48552d51662160104b62 mining: rename getCoinbaseTx() to ..RawTx() (Sjors Provoost)
Pull request description:
The first commit renames `getCoinbaseTx()` to `getCoinbaseRawTx()` to reflect that it returns a serialised transaction. This does not impact IPC clients, because they do not use the function name.
The second commit then introduces a replacement `getCoinbase()` that provides a struct with everything clients need to construct a coinbase. This avoids clients having to parse and manipulate our dummy transaction.
Deprecate but don't remove `getCoinbaseRawTx()`, `getCoinbaseCommitment()` and `getWitnessCommitmentIndex()`.
After this change we can drop these deprecated methods, which in turn would allow us to clear the dummy transaction from the `getBlock()` result. But that is left for a followup to keep this PR focussed. See https://github.com/Sjors/bitcoin/pull/106 for an approach.
Expand the `interface_ipc.py` functional test to document its usage.
Can be tested using:

This makes the code more consistent.
Also, use "using BenchFunction = ..." while touching the header.
Also, fixup the whitespace after and earlier scripted-diff.
Duplicate benchmarks with the same name are not supported. Expanding the
name with __LINE__ is confusing and brittle, because it makes duplication
bugs silent.
Fix this twofold:
* By enforcing unique benchmarks at compile-time and link-time. For
example, a link failure may now look like:
"mold: error: duplicate symbol: bench_runner_AddrManAdd"
* By enforcing unique benchmarks at run-time. This should never happen,
due to the build-failure, but a failure may look like:
"Assertion `benchmarks().try_emplace(std::move(name), std::move(func)).second' failed."
The Restore Wallet dialog rejects wallet names that are empty, but was
doing so silently. This is confusing, we should be presenting an error
message to the user.
After the normal optimization process finishes, and finds an optimal
spanning forest, run a second process (while computation budget remains)
to split chunks into minimal equal-feerate chunks.

To improve privacy, broadcast locally submitted transactions (from the `sendrawtransaction` RPC) to the P2P network only via Tor or I2P short-lived connections, or to IPv4/IPv6 peers but through the Tor network.
* Introduce a new connection type for private broadcast of transactions with the following properties:
* started whenever there are local transactions to be sent
* opened to Tor or I2P peers or IPv4/IPv6 via the Tor proxy
* opened regardless of max connections limits
* after handshake is completed one local transaction is pushed to the peer, `PING` is sent and after receiving `PONG` the connection is closed
* ignore all incoming messages after handshake is completed (except `PONG`)
* Broadcast transactions submitted via `sendrawtransaction` using this new mechanism, to a few peers. Keep doing this until we receive back this transaction from one of our ordinary peers (this takes about 1 second on mainnet).
* The transaction is stored in peerman and does not enter the mempool.
* Once we get an `INV` from one of our ordinary peers, then the normal flow executes: we request the transaction with `GETDATA`, receive it with a `TX` message, put it in our mempool and broadcast it to all our existent connections (as if we see it for the first time).
* After we receive the full transaction as a `TX` message, in reply to our `GETDATA` request, only then consider the transaction has propagated through the network and remove it from the storage in peerman, ending the private broadcast attempts.
The messages exchange should look like this:
```
tx-sender >--- connect -------> tx-recipient
tx-sender >--- VERSION -------> tx-recipient (dummy VERSION with no revealing data)
tx-sender <--- VERSION -------< tx-recipient
tx-sender <--- WTXIDRELAY ----< tx-recipient (maybe)
tx-sender <--- SENDADDRV2 ----< tx-recipient (maybe)
tx-sender <--- SENDTXRCNCL ---< tx-recipient (maybe)
tx-sender <--- VERACK --------< tx-recipient
tx-sender >--- VERACK --------> tx-recipient
tx-sender >--- INV/TX --------> tx-recipient
tx-sender <--- GETDATA/TX ----< tx-recipient
tx-sender >--- TX ------------> tx-recipient
tx-sender >--- PING ----------> tx-recipient
tx-sender <--- PONG ----------< tx-recipient
tx-sender disconnects
```
Whenever a new transaction is received from `sendrawtransaction` RPC, the node will send it to a few (`NUM_PRIVATE_BROADCAST_PER_TX`) recipients right away. If after some time we still have not heard anything about the transaction from the network, then it will be sent to 1 more peer (see `PeerManagerImpl::ReattemptPrivateBroadcast()`).
A few considerations:
* The short-lived private broadcast connections are very cheap and fast wrt network traffic. It is expected that some of those peers could blackhole the transaction. Just one honest/proper peer is enough for successful propagation.
* The peers that receive the transaction could deduce that this is initial transaction broadcast from the transaction originator. This is ok, they can't identify the sender.

<summary>How to test this?</summary>
Thank you, @stratospher and @andrewtoth!
Start `bitcoind` with `-privatebroadcast=1 -debug=privatebroadcast`.
Create a wallet and get a new address, go to the Signet faucet and request some coins to that address:
```bash
build/bin/bitcoin-cli -chain="signet" createwallet test
build/bin/bitcoin-cli -chain="signet" getnewaddress
```
Get a new address for the test transaction recipient:
```bash
build/bin/bitcoin-cli -chain="signet" loadwallet test
new_address=$(build/bin/bitcoin-cli -chain="signet" getnewaddress)
```
Create the transaction:
```bash
# Option 1: `createrawtransaction` and `signrawtransactionwithwallet`:
txid=$(build/bin/bitcoin-cli -chain="signet" listunspent | jq -r '.[0] | .txid')
vout=$(build/bin/bitcoin-cli -chain="signet" listunspent | jq -r '.[0] | .vout')
echo "txid: $txid"
echo "vout: $vout"
tx=$(build/bin/bitcoin-cli -chain="signet" createrawtransaction "[{\"txid\": \"$txid\", \"vout\": $vout}]" "[{\"$new_address\": 0.00001000}]" 0 false)
echo "tx: $tx"
signed_tx=$(build/bin/bitcoin-cli -chain="signet" signrawtransactionwithwallet "$tx" | jq -r '.hex')
echo "signed_tx: $signed_tx"
# OR Option 2: `walletcreatefundedpsbt` and `walletprocesspsbt`:
# This makes it not have to worry about inputs and also automatically sends back change to the wallet.
# Start `bitcoind` with `-fallbackfee=0.00003000` for instance for 3 sat/vbyte fee.
psbt=$(build/bin/bitcoin-cli -chain="signet" walletcreatefundedpsbt "[]" "[{\"$new_address\": 0.00001000}]" | jq -r '.psbt')
echo "psbt: $psbt"
signed_tx=$(build/bin/bitcoin-cli -chain="signet" walletprocesspsbt "$psbt" | jq -r '.hex')
echo "signed_tx: $signed_tx"
```
Finally, send the transaction:
```bash
raw_tx=$(build/bin/bitcoin-cli -chain="signet" sendrawtransaction "$signed_tx")
echo "raw_tx: $raw_tx"
```

Further extensions:
* Have the wallet do the private broadcast as well, https://github.com/bitcoin/bitcoin/issues/11887 would have to be resolved.
* Have the `submitpackage` RPC do the private broadcast as well, [draft diff in the comment below](https://github.com/bitcoin/bitcoin/pull/29415#pullrequestreview-2972293733), thanks ismaelsadeeq!
* Add some stats via RPC, so that the user can better monitor what is going on during and after the broadcast. Currently this can be done via the debug log, but that is not convenient.
* Make the private broadcast storage, currently in peerman, persistent over node restarts.
* Add (optional) random delay before starting to broadcast the transaction in order to avoid correlating unrelated transactions based on the time when they were broadcast. Suggested independently of this PR [here](https://github.com/bitcoin/bitcoin/issues/30471).
* Consider periodically sending transactions that did not originate from the node as decoy, discussed [here](https://github.com/bitcoin/bitcoin/pull/29415#discussion_r2035414972).
* Consider waiting for peer's FEEFILTER message and if the transaction that was sent to the peer is below that threshold, then assume the peer is going to drop it. Then use this knowledge to retry more aggressively with another peer, instead of the current 10 min. See [comment below](https://github.com/bitcoin/bitcoin/pull/29415#issuecomment-3258611648).
* It may make sense to be able to override the default policy -- eg so submitrawtransaction can go straight to the mempool and relay, even if txs are normally privately relayed. See [comment below](https://github.com/bitcoin/bitcoin/pull/29415#issuecomment-3427086681).
* As a side effect we have a new metric available - the time it takes for a transaction to reach a random node in the network (from the point of view of the private broadcast recipient the tx originator is a random node somewhere in the network). This can be useful for monitoring, unrelated to privacy characteristics of this feature.
---
_A previous incarnation of this can be found at https://github.com/bitcoin/bitcoin/pull/27509. It puts the transaction in the mempool and (tries to) hide it from the outside observers. This turned out to be too error prone or maybe even impossible._

`ChainstateManager::IsInitialBlockDownload()` is queried on hot paths and previously acquired `cs_main` internally, contributing to lock contention.
Cache the IBD status in `m_cached_is_ibd`, and introduce `ChainstateManager::UpdateIBDStatus()` to latch it once block loading has finished and the current chain tip has enough work and is recent.
Call the updater after tip updates and after `ImportBlocks()` completes.
Since `IsInitialBlockDownload()` no longer updates the cache, drop `mutable` from `m_cached_is_ibd` and only update it from `UpdateIBDStatus()` under `cs_main`.
Update the new unit test to showcase the new `UpdateIBDStatus()`.

Factor the chain tip work/recency check out of `ChainstateManager::IsInitialBlockDownload()` into a reusable `CChain::IsTipRecent()` helper, and annotate it as requiring `cs_main` since it's reading mutable state.
Also introduce a local `chainman_ref` in the kernel import-blocks wrapper to reduce repetition and keep follow-up diffs small.
`IsInitialBlockDownload` returns were also unified to make the followup move clean.

Rename and invert the internal IBD latch so the cached value directly matches `IsInitialBlockDownload()` (true while in IBD, then latched to false).
This is a behavior-preserving refactor to avoid double negatives.
Add a unit test that exercises the `IsInitialBlockDownload()` decision matrix by varying the cached latch, `BlockManager::LoadingBlocks()`, and tip work/recency inputs.
This documents the current latching behavior and provides a baseline for later refactors.

`CCoinsViewCache::FetchCoin()` had special handling for a spent `Coin` returned by the parent view.
Production parents (`CCoinsViewCache` and `CCoinsViewDB`) do not return spent coins, so this path is unreachable.
Replace it with an `Assume(!coin.IsSpent())`, drop outdated documentation about spent+FRESH cache entries, and simplify `SanityCheck()` to assert the remaining possible state invariants.
This is safe because it does not change behavior for valid backends and will fail fast if the `GetCoin()` contract is violated.

Use port=0 for dynamic port allocation in test framework components
to avoid "address already in use" errors from concurrent tests or
ports stuck in TIME_WAIT state from previous test runs.
Changes:
- socks5.py: Update conf.addr after bind() to reflect actual port
- p2p.py: Retrieve actual port after create_server() when port=0
- feature_proxy.py: Use port=0 for all SOCKS5 proxy servers
- feature_anchors.py: Use port=0 for onion proxy server
- No need to jump into the next subroutine when there is no conflict.
- This makes it clear why it is necessary to have two calls of
CheckMempoolPolicyLimts in both PackageMempoolChecks and after in
AcceptMultipleTransactionsInternal, there is a possibilty that we
we want to accept multiple transaction but they are not conflicting
with any in-mempool transaction, in that case also we want to check
that they do not bust the cluster limits.

eeaf28dbe0e09819ab0e95bb7762b29536bdeef6 wallet: test: Failed migration cleanup (David Gumberg)
Pull request description:
Prior to https://github.com/bitcoin/bitcoin/pull/34156, an issue existed where if migration of a wallet with a relative pathname failed, the relatively specified path where the legacy wallet is would be deleted. This issue predates #32273, because the relative pathnames get stacked together, e.g. "../../", the copy conflict bug that caused migration to abort early instead of getting far enough to attempt clean-up that was fixed in #32273 is avoided.
This is a functional test demonstrating that we handle failed migration clean-up correctly for relatively-named wallets. To see the issue, you can backport this test onto 29.x: https://github.com/davidgumberg/bitcoin/tree/2026-01-07-rel-migration-test-backport
I've also added an absolute path failed migration cleanup test. WRT this and #34156, absolute paths exhibit similar behavior to unnamed wallets. Because of the name-conflict bug prior to #32273 an absolute-path migration would fail no matter what because migration would attempt to copy a file to a destination that already exists. But after #32273, absolute-path migration gets past there, and if it fails for some other reason, the same behavior that's fixed in #34156 occurs where the directory containing the wallet file is deleted.

An interrupt does not create a failure exit code during normal
operation. This should also be the case when interrupt is triggered
during initialization. However a failure exit code is currently returned
if an interrupt occurs during init. Fix this by making `AppInitMain` return
true instead of false, which further up the call stack sets the
`EXIT_FAILURE` code. Also add a check for the interrupt condition during
GUI startup.

They are exactly the same, but the descriptor utils should not prescribe
to use the FuzzBufferType. Using a dedicated type for them clarifies
that the utils are not tied to FuzzBufferType.
Also, while touching the lines, use `const` only where it is meaningful.
