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.

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._

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.

cbf0bd35bbf312f3b13d92d281d7112e4b43b9c3 test: migration, avoid backup name mismatch in default_wallet_failure (furszy)
Pull request description:
This is a possible test failure, pushing it in case the CI starts complaining.
The change affects only test code; no cpp logic is involved.
The `test_default_wallet_failure` migration test calls the function
`migrate_and_get_rpc()`, which sets the mock time internally. But, at the
same time, the test already caches the mock time value, to later use it
in the backup existence check.
Setting the mock time twice can lead to a name mismatch during the
mentioned check (diff timestamp == diff backup names), which could
cause the test to fail.
The fix is very simple, just need to call the migration RPC directly.
Since the test expects the migration to fail, `migrate_and_get_rpc()` is
unnecessary here. I'm surprised the CI hasn't complained about this yet.

The test calls migrate_and_get_rpc(), which sets mock time internally.
The caller caches a mock time value and later relies on it to predict the
backup filename, so setting the mock time again could cause a naming
mismatch.
Fix this by calling the migration RPC directly. Since the test expects the
migration to fail, migrate_and_get_rpc() is unnecessary here.
f78f6f1dc8e16d5a8a23749e77bc3bf17c91ae42 wallettool: do not use fs::remove_all in createfromdump cleanup (Ava Chow)
Pull request description:
As pointed out in https://github.com/bitcoin/bitcoin/pull/34156#issuecomment-3716728670, it is possible for `createfromdump` to also accidentally delete the entire wallets directory if the wallet name is the empty string and the dumpfile contains a checksum error.
This is also fixed by removing the files created by only removing the directory for named wallets, and avoiding the use of `fs::remove_all`.

Pull request description:
Minimal fix for #34128.
The issue occurs during the migration of a legacy unnamed wallet
(the legacy "default" wallet). When the migration fails, the cleanup
logic is triggered to roll back the state, which involves erasing the
newly created descriptor wallets directories. Normally, this only
affects the parent directories of named wallets, since they each
reside in their own directories. However, because the unnamed
wallet resides directly in the top-level `/wallets/` folder, this
logic accidentally deletes the main directory.
The fix ensures that only the wallet.dat file of the unnamed wallet
is touched and restored, preserving the wallet in BDB format and
leaving the main `/wallets/` directory intact.
#### Story Line:
#32273 fixed a different set of issues and, in doing so, uncovered
this one.
Before the mentioned PR, backups were stored in the same directory
as the wallet.dat file. On a migration failure, the backup was then
copied to the top-level `/wallets/` directory. For the unnamed legacy
wallet, the wallet directory is the `/wallets/` directory, so the source
and destination paths were identical. As a result, we threw early in the
`fs::copy_file` call ([here](https://github.com/bitcoin/bitcoin/blob/29.x/src/wallet/wallet.cpp#L4572)) because the file already existed, as we
were trying to copy the file onto itself. This caused the cleanup logic
to abort early on and never reach the removal line.
#### Testing Notes:
Cherry-pick the test commit on top of master and run it. You will
see the failure and realize the reason by reading the test code.

fafbc70d48e1fb42c4ed3da609e5f30c4cc39418 rpc: [wallet] Use unsigned type for tx version in sendall (MarcoFalke)
Pull request description:
It is confusing to parse the unsigned tx version as a signed type. Also, it makes it harder to use the integer sanitizer.
Can be tested via:
* Build with the flags `-DCMAKE_C_COMPILER='clang' -DCMAKE_CXX_COMPILER='clang++' -DSANITIZERS=undefined,integer,float-divide-by-zero`
* Set the existing suppressions: `export UBSAN_OPTIONS="suppressions=$(pwd)/test/sanitizer_suppressions/ubsan:print_stacktrace=1:halt_on_error=0:report_error_type=1"`
* Start the RPC server, e.g. `./bld-cmake/bin/bitcoin-qt -datadir=/tmp -regtest -server`
* Call the sendall RPC, e.g. `./bld-cmake/bin/bitcoin-cli -datadir=/tmp -regtest -named sendall '["bcrt1qlrt3xps4wxpfcjmljrayr2ualczmnfvd4vzdq3"]' fee_rate=1.234 version=-1`

Because the default wallet has no name, the watch-only and solvables
wallets created during migration end up having no name either.
This fixes it by applying the same prefix name we use for the backup
file for an unnamed default wallet.
Before: watch-only wallet named "_watchonly"
After: watch-only wallet named "default_wallet_watchonly"
Right now, after migration the last message users see is "migration completed",
but the migration isn't actually finished yet. We still need to load the new wallets
to ensure consistency, and if that fails, the migration will be rolled back. This
can be confusing for users.
This change logs the post-migration loading step and if a wallet fails to load and
the migration will be rolled back.
The first test verifies that restoring into an existing empty directory
or a directory with no .dat db files succeeds, while restoring into a
dir with a .dat file fails.
The second test covers restoring into the default unnamed wallet
(wallet.dat), which also implicitly exercises the recovery path used
after a failed migration.
The third test covers failure during restore on a prune node. When
the wallet last sync was beyond the pruning height.
When migrating any legacy unnamed wallet, a failed migration would
cause the cleanup logic to remove its parent directory. Since this
type of legacy wallet lives directly in the main '/wallets/' folder,
this resulted in unintentionally erasing all wallets, including the
backup file.
To be fully safe, we will no longer call `fs::remove_all`. Instead,
we only erase the individual db files we have created, leaving
everything else intact. The created wallets parent directories are
erased only if they are empty.
As part of this last change, `RestoreWallet` was modified to allow
an existing directory as the destination, since we no longer remove
the original wallet directory (we only remove the files we created
inside it). This also fixes the restore of top-level default wallets
during failures, which were failing due to the directory existence
check that always returns true for the /wallets/ directory.
This bug started after:
f6ee59b6e2
Previously, the `fs::copy_file` call was failing for top-level wallets,
which prevented the `fs::remove_all` call from being reached.
Track what RestoreWallet creates so only those files and directories
are removed during a failure and nothing else. Preexisting paths
must be left untouched.
Note:
Using fs::remove_all() instead of fs::remove() in RestoreWallet does
not cause any problems currently, but the change is necessary for the
next commit which extends RestoreWallet to work with existing directories,
which may contain files that must not be deleted.

Pull request description:
Part of #30289, follow-up to #32545.
This gets rid of `FixLinearization()` by integrating the functionality into `Linearize()`, and makes txgraph exploit that (by delaying fixing of clusters until their first re-linearization). It also reduces (but does not eliminate) the number of calls to `PostLinearize`, as the SFL linearization effectively performs something very similar to postlinearization when loading in an existing linearization already.

Pull request description:
The ctest target `bench_sanity_check` has many issues:
* With sanitizers enabled, it is one of the slowest targets, often taking several minutes. See https://github.com/bitcoin/bitcoin/issues/32770#issuecomment-2984264066.
* There is no insight from ctest into how long each individual sanity check takes.
* On a timeout, or OOM issue, there is no insight into which sub-bench failed. The failure will generally just look like `75/153 Test #9: bench_sanity_check ...................***Failed 770.84 sec out of memory`
* Places that can't use ctest (like the Windows-cross CI task) have to explicitly run it, or risk forgetting to run it.
* All benchmarks are run sequentially, when they could run in parallel instead.
Both issues can lead to CI timeouts and leave CPU unused during testing.
Fix all issues by running it as part of the functional tests instead. This is similar to the rpcauth tests (https://github.com/bitcoin/bitcoin/pull/32881) and util tests [bitcoin-tx, and bitcoin-util] (https://github.com/bitcoin/bitcoin/pull/32697).

4ce3f4a26565e9851af950728cda7bcc2242d0c2 rpc, net: deprecate `startingheight` field of `getpeerinfo` RPC (Sebastian Falbesoner)
Pull request description:
This PR deprecates the "startingheight" result field of the `getpeerinfo` RPC, following the discussion in #33990.
Rationale: the reported starting height of a peer in the VERSION message is untrusted, and it doesn't seem to be useful anymore (after #20624), so deprecating the corresponding field seems reasonable. After that, it can be removed, along with the `m_starting_height` field of the Peer / CNodeStats structs, as it is sufficient to show the reported height only once at connection in the debug log.

With the new SFL algorithm, the process of loading an existing linearization into the
SFL state is very similar to what PostLinearize does. This means there is little benefit
to performing an explicit PostLinearize step before linearizing inside txgraph. Instead,
it seems better to use our allotted CPU time to perform more SFL optimization steps.
With the SFL algorithm, we will practically be capable of keeping
most if not all clusters optimal. With that, it seems less valuable
to avoid doing work after splitting an acceptable cluster, because by
doing some work we may get it to OPTIMAL.
This reduces the complexity of the code a bit as well.
