72b226882fe2348a9a66aee1d8d21b4e2d275e68 wallet: notify when preset + automatic inputs exceed max weight (furszy)
Pull request description:
Small change. Found it while finishing my review on #29523. This does not interfere with it.
Basically, we are erroring out early when the automatic coin selection process exceeds the maximum weight, but we are not doing so when the user-preselected inputs combined with the wallet-selected inputs exceed the maximum weight.
This change avoids signing all inputs before erroring out and introduces test coverage for `fundrawtransaction`.

Pull request description:
Introduce a `Mining` interface for the `getblocktemplate`, `generateblock` and other mining RPCs to use now, and for Stratum v2 to use later.
Suggested here: https://github.com/bitcoin/bitcoin/pull/29346#issuecomment-2108528652
The selection of methods added to the interface is mostly based on what the Template Provider in #29432 uses. It could be expanded further so that `rpc/mining.cpp` no longer needs `EnsureMemPool` and `EnsureChainman`.
This PR should be a pure refactor.

This test type is represented using SEND_NO_AAD. If AAD of the first encrypted packet
sent after the garbage terminator (optional decoy packet/version packet) hasn't been
filled, disconnection happens.
This test type is represented using WRONG_GARBAGE.
Here, garbage bytes sent to TestNode are assumed to be tampered with and
do not correspond to the garbage bytes which P2PInterface calculated and
uses.
This test type is represented using WRONG_GARBAGE_TERMINATOR.
since the wrong garbage terminator is sent to TestNode, TestNode
will interpret all of the gabage bytes, wrong garbage terminator,
decoy messages and version packet it receives as garbage bytes.
If the length of all these is more than 4095 + 16, it will result
in a missing garbage terminator error. otherwise, it will result
in a V2 handshake timeout error.
Send only MAX_GARBAGE_LEN//2 bytes of garbage data to TestNode
so that the total length received by the TestNode is at max
= (MAX_GARBAGE_LEN//2) + 16 + 10*120 + 20 = 3283 bytes
(which is less than 4095 + 16 bytes) and we get a consistent
V2 handshake timeout error message.
If we do not limit the garbage length sent, we will intermittently
get both missing garbage terminator error and V2 handshake
timeout error based on the garbage length and decoy packets length
which are chosen at random.

Pull request description:
So far, discouragement of peers triggers when their misbehavior score exceeds 100 points. Most types of misbehavior increment the score by 100, triggering immediate discouragement, but some types do not. This PR makes all increments equal to either 100 (meaning any misbehavior will immediately cause disconnection and discouragement) or 0 (making the behavior effectively unconditionally allowed), and then removes the logic for score accumulation.
This simplifies the code a bit, but also makes protocol expectations clearer: if a peer misbehaves, they get disconnected. There is no good reason why certain types of protocol violations should be permitted 4 times (howmuch=20) or 9 times (howmuch=10), while many others are never allowed. Furthermore, the distinction between these looks arbitrary.
The specific types of misbehavior that are changed to 100 are:
* Sending us a `block` which does not connect to our header tree (which necessarily must have been unsollicited). [used to be score 10]
* Sending us a `headers` with a non-continuous headers sequence. [used to be score 20]
* Sending us more than 1000 addresses in a single `addr` or `addrv2` message [used to be score 20]
* Sending us more than 50000 invs in a single `inv` message [used to be score 20]
* Sending us more than 2000 headers in a single `headers` message [used to be score 20]
The specific types of misbehavior that are changed to 0 are:
* Sending us 10 (*) separate BIP130 headers announcements that do not connect to our block tree [used to be score 20]
* Sending us more than 8 headers in a single `headers` message (which thus does not get treated as a BIP130 announcement) that does not connect to our block tree. [used to be score 10]
I believe that none of these behaviors are unavoidable, except for the one marked (*) which can in theory happen still due to interaction between BIP130 and variations in system clocks (the max 2 hour in the future rule). This one has been removed entirely. In order to remove the impact of the bug it was designed to deal with, without relying on misbehavior, a separate improvement is included that makes `getheaders`-tracking more accurate.
In another unrelated improvement, this also gets rid of the 8 header limit heuristic to determine whether an incoming non-connecting `headers` is a potential BIP130 announcement, as this rule is no longer needed to prevent spurious Misbehavior. Instead, any non-connecting `headers` is now treated as a potential announcement.

Pull request description:
Allows any 2 transaction package with no in-mempool ancestors to do package RBF when directly conflicting with other mempool clusters of size two or less.
Proposed validation steps:
1) If the transaction package is of size 1, legacy rbf rules apply.
2) Otherwise the transaction package consists of a (parent, child) pair with no other in-mempool ancestors (or descendants, obviously), so it is also going to create a cluster of size 2. If larger, fail.
3) The package rbf may not evict more than 100 transactions from the mempool(bip125 rule 5)
4) The package is a single chunk
5) Every directly conflicted mempool transaction is connected to at most 1 other in-mempool transaction (ie the cluster size of the conflict is at most 2).
6) Diagram check: We ensure that the replacement is strictly superior, improving the mempool
7) The total fee of the package, minus the total fee of what is being evicted, is at least the minrelayfee * size of the package (equivalent to bip125 rule 3 and 4)
Post-cluster mempool this will likely be expanded to general package rbf, but this is what we can safely support today.

Pull request description:
While reviewing #28307, I noticed that the test framework's `key_to_multisig_script` helper (introduced in #23305) is broken for pubkey count (n) and threshold (k) values larger than 16. This is due to the implementation currently enforcing a direct single-byte data push (using `CScriptOp.encode_op_n`), which obviously fails for values 17+. Fix that by passing the numbers directly to the CScript list, where it's automatically converted to minimally-encoded pushes (see class method `CScript.__coerce_instance`, branch `isinstance(other, int)`).
The second commit adds a unit test to ensure that the encoding is correct.

Prior to this commit, TestEncryptedP2PState would always
send initial_v2_handshake bytes in 2 parts (as required
by early key response test).
For generalising this test and having different v2 handshake
behaviour based on the test type, special behaviours like
sending initial_v2_handshake bytes in 2 parts are executed
only if test_type is set to EARLY_KEY_RESPONSE.
Adds argument --resultsfile to test_runner.py.

436e88f4336199998184cbfa5d1c889ffaefbfb5 bumpfee: ignore WALLET_INCREMENTAL_RELAY_FEE when user specifies fee rate (ismaelsadeeq)
Pull request description:
Fixes#26973
When using the `bumpfee` RPC and manually specifying `fee_rate`, there should be no requirement that the new fee must be at least the sum of the original fee and `incrementalFee` (maximum of `relayIncrementalFee` and `WALLET_INCREMENTAL_RELAY_FEE`).
This restriction should only apply when user did not specify `fee_rate`.
> because the GUI doesn't let the user specify the new fee rate yet (https://github.com/bitcoin-core/gui/issues/647), it would be very annoying to have to bump 20 times to increment by 20 sat/vbyte.
The restriction should instead be the new fee must be at least the sum of the original fee and `incrementalFee` (`relayIncrementalFee`)

27e70f1f5be1f536f2314cd2ea42b4f80d927fbd consensus: Store transaction nVersion as uint32_t (Ava Chow)
Pull request description:
Given that the use of a transaction's nVersion is always as an unsigned int, it doesn't make sense to store it as signed and then cast it to unsigned everywhere it is used and displayed.
Since a few alternative implementations have recently been revealed to have made an error with this signedness that would have resulted in consensus failure, I think it makes sense for us to just make this always unsigned to make it clear that the version is treated as unsigned. This would also help us avoid future potential issues with signedness of this value.
I believe that this is safe and does not actually change what transactions would or would not be considered both standard and consensus valid. Within consensus, the only use of the version in consensus is in BIP68 validation which was already casting it to uint32_t. Within policy, although it is used as a signed int for the transaction version number check, I do not think that this change would change standardness. Standard transactions are limited to the range [1, 2]. Negative numbers would have fallen under the < 1 condition, but by making it unsigned, they are still non-standard under the > 2 condition.
Unsigned and signed ints are serialized and unserialized the same way so there is no change in serialization.

59a6df6bd584701f820ad60a10d9d477bf0236b5 util: add BitSet (Pieter Wuille)
Pull request description:
Extracted from #30126.
This introduces the `BitSet` data structure, inspired by `std::bitset`, but with a few features that cannot be implemented on top without efficiency loss:
* Finding the first set bit (`First`)
* Finding the last set bit (`Last`)
* Iterating over all set bits (`begin` and `end`).
And a few other operators/member functions that help readability for #30126:
* `operator-` for set subtraction
* `Overlaps()` for testing whether intersection is non-empty
* `IsSupersetOf()` for testing (non-strict) supersetness
* `IsSubsetOf()` for testing (non-strict) subsetness
* `Fill()` to construct a set with all numbers from 0 to n-1, inclusive
* `Singleton()` to construct a set with one specific element.
Everything is tested through a simulation-based fuzz test that compares the behavior with normal `std::bitset` equivalent operations.

Pull request description:
Adds invalid port detection to bitcoin-cli for -rpcconnect and -rpcport.
In addition to detecting malformed/invalid ports (e.g. those outside of the 16-bit port range, not numbers, etc.), bitcoin-cli also now considers usage of port 0 to be invalid. bitcoin-cli previously considered port 0 to be valid and attempted to use it to reach bitcoind.
Functional tests were added for invalid port detection as well as port prioritization.
Additionally, a warning is provided when a port is specified in both -rpcconnect and -rpcport.
This PR is an alternate approach to PR #27820 (e.g. SplitHostPort is unmodified).
Considered an alternative to 127.0.0.1 being specified in functional tests, but at first glance, this might need an update to test_framework/util.py (e.g. rpc_url), which might be left to a future PR.

Not every pseudorandom hash result is a valid x-only public key,
so the pubkey tweaking in the course of creating the output public
key would fail about every second time.
Fix this by treating the hash result as private key and calculate
the x-only public key out of that, to be used then as internal key.

0000276b31cea5e443a59d94a98c569293ada951 test: Remove redundant verack check (MarcoFalke)
Pull request description:
Currently the sync in `connect_nodes` mentions the `version` and `verack` message types, but only checks the `verack`. Neither check is required, as the `pong` check implies both. In case of failure, the debug log will have to be consulted anyway, so the redundant check doesn't add value.
Also clarify in the comments that the goal is to check the flag `fSuccessfullyConnected` indirectly.

This commit fixes a dormant bug in MiniWallet that exists since
support for P2TR was initially added in #23371 (see commit
041abfebe49ae5e3e882c00cc5caea1365a27a49).
In the course of spending the output, the leaf version byte of the
control block in the witness stack doesn't set the parity bit, i.e.
we were so far just lucky that the used combinations of relevant
data (internal pubkey, leaf script / version) didn't result in a
tweaked pubkey with odd y-parity. If that was the case, we'd get the
following validation error:
`mandatory-script-verify-flag-failed (Witness program hash mismatch) (-26)`
Since MiniWallets can now optionally be tagged (#29939), resulting
in different internal pubkeys, the issue is more prevalent now.
Fix it by passing the parity bit, as specified in BIP341.
Rather than only returning the internal key from the P2TR anyone-can-spend
address creation routine, provide the whole TaprootInfo object, which in turn
contains a dictionary of TaprootLeafInfo object for named leaves.
This data is used in MiniWallet for the default ADDRESS_OP_TRUE mode, in order
to deduplicate the witness script and leaf version of the control block.

c17550bc3a68faa1eb82d1bdb767b41d8cd85a6b test: MiniWallet: fix tx padding (`target_weight`) for large sizes, improve accuracy (Sebastian Falbesoner)
Pull request description:
MiniWallet allows to create padded transactions that are equal or slightly above a certain `target_weight` (first introduced in PR #25379, commit 1d6b438ef0ccd05e1522ac38b44f847c1d93e72f), which can be useful especially for mempool-related tests, e.g. for policy limit checks or scenarios to trigger mempool eviction. Currently the `target_weight` parameter doesn't play together with `fee_rate` though, as the fee calculation is incorrectly based on the tx vsize before the padding output is added, so the fee-rate is consequently far off. This means users are forced to pass an absolute fee, which can be quite inconvenient and leads to lots of duplicated "calculate absolute fee from fee-rate and vsize" code with the pattern `fee = (feerate / 1000) * (weight // 4)` on the call-sites.
This PR first improves the tx padding itself to be more accurate, adds a functional test for it, and fixes the `fee_rate` treatment for the `{create,send}_self_transfer` methods. (Next step would be to enable this also for the `_self_transfer_multi` methods, but those currently don't even offer a `fee_rate` parameter). Finally, the ability to pass both `target_weight` and `fee_rate` is used in the `mempool_limit.py` functional test. There might be more use-cases in other tests, that could be done in a follow-up.

Pull request description:
When restarting `bitcoind` during an ongoing reindex without setting the `-reindex` flag again, the block and coins db is left intact, but any data from the optional indexes is discarded. While not a bug per se, wiping the data again is
wasteful, both in terms of having to write it again, as well as potentially leading to longer startup times. So keep the index data instead when continuing a prior reindex.
Also includes a bugfix and smaller code cleanups around the reindexing code. The bug was introduced in b47bd959207e82555f07e028cc2246943d32d4c3: "kernel: De-globalize fReindex".

of std::bitset with a few additional features that cannot be implemented
in a wrapper without performance loss (specifically, finding first and
last bit set, or iterating over all set bits).

In order to ensure that the change of nVersion to a uint32_t in the
previous commit has no effect, rename nVersion to version in this commit
so that reviewers can easily spot if a spot was missed or if there is a
check somewhere whose semantics have changed.
