ded11fb04d8231dd820bfa04b11a4b7b2b0a06f8 test: fix interface_ipc.py template destruction (Ryan Ofsky)
Pull request description:
This PR cleans up the `interface_ipc.py` test, fixing broken checks, fixing missing await calls, removing to_dict calls, renaming variables, reducing `.result` accesses, and giving template objects explicit lifetimes. More details are in the commit messages.
The first commit changes a lot of indentation so is easiest to review ignoring whitespace.

09dfa4d3f8dfbea61a73d4add79e2464ca776571 test: fix race condition in p2p_v2_misbehaving.py peerid assertion (stratospher)
Pull request description:
Remove the hard-coded peer id from the debug message in `p2p_v2_misbehaving.py`.
asyncio's non-deterministic task scheduling might cause [peer2](938d7aacab/test/functional/p2p_v2_misbehaving.py (L181))'s connection to happen before [peer1](938d7aacab/test/functional/p2p_v2_misbehaving.py (L179))'s. since we test that peer2 [remains connected](938d7aacab/test/functional/p2p_v2_misbehaving.py (L182)), any disconnection must originate from peer1, making the specific peer id not necessary for test correctness. so we can remove the hard coded peer id from the expected debug log message.
Fixes#34035.

Pull request description:
`LogPrintLevel` has many issues:
* It encourages to log several levels in one source location. This is problematic, because all levels (even warnings and errors) will be rate limited equally for the same location.
* Its warning and error logs are specially formatted compared to all other warning and error logs in the codebase, making them harder to spot (both in the debug log and in the code).
* It is verbose to type and read.
* It is confusing, because the majority of code uses the `Log$LEVEL(...)` macros. Having less ways to achieve the same makes the code more consistent and easier to review.
Fix all issues by removing it

due to asyncio's non-deterministic task scheduling, peer2's
connection might happen before peer1's, causing peer2 to get
assigned peer_id=1 on bitcoind side and peer1 to get assigned
peer_id=2 on bitcoind side.
since we test that peer2 remains connected, any disconnection
must originate from peer1, making the specific peer id unnecessary
for test correctness. so we can remove the specific peer_id from
the expected debug log.

Pull request description:
"tor" as a network specification was deprecated in 60dc8e4208 in favor of "onion"
and this commit removes it and updates the relevant test.
Previously #16029. This has been warning as being deprecated since `v0.17.0`.
This PR only removes the already deprecated usage of tor as a network specification, the use of tor throughout the codebase, is not deprecated.

2f51951d03cc1f8917e0fc931dce674f9bfedaf5 p2p: Add warning message when receiving headers for blocks cached as invalid (Martin Zumsande)
Pull request description:
In case of corruption that leads to a block being marked as invalid that is seen as valid by the rest of the network, the user currently doesn't receive good error messages, but will often be stuck in an endless headers-sync loop with no explanation (#26391).
This PR improves warnings in two ways:
- When we receive a header that is already saved in our disk, but invalid, add a warning. This will happen repeatedly during the headerssync loop (see https://github.com/bitcoin/bitcoin/issues/26391#issuecomment-1291765534 on how to trigger it artificially).
- Removes the IBD check from `CheckForkWarningConditions` and adds a call to the function during init (`LoadChainTip()`). The existing check was added in 55ed3f1475 a long time ago when we had more sophisticated fork detection that could lead to false positives during IBD, but that logic was removed in fa62304c97 so that I don't see a reason to suppress the warning anymore.
Fixes#26391 (We'll still do the endless looping, trying to find a peer with a headers that we can use, but will now repeatedly log warnings while doing so).

a7c96f874de13ace9814da92fd6160a126a97ebf tests: Add witness commitment if we have a witness transaction in FullBlockTest.update_block() (Chris Stewart)
Pull request description:
This is useful for test cases where we want to test logic invalid blocks that contain witness transactions. If we don't add the witness commitment as per [BIP141](https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki#user-content-Commitment_structure), blocks will be rejected with the error [`Block mutated`](fb0ada982a/src/validation.cpp (L4180)).
This change was needed in https://github.com/ajtowns/bitcoin/pull/13 which is a soft fork proposal to disallow 64 byte transactions. We want to test that 64 byte transactions serialized without the witness are invalid. If we do not have this change, we cannot directly test the logic that rejects 64 byte transactions.
I decided to PR this upstream as many soft fork proposals may not see the light of day, but this functionality seems strictly additive to the test framework.

9d5021a05bd33c73276909eec961777867ddb412 script: add SCRIPT_ERR_TAPSCRIPT_EMPTY_PUBKEY (billymcbip)
Pull request description:
We currently have two callsites for `SCRIPT_ERR_PUBKEYTYPE`:
- A pre-tapscript policy error behind the `SCRIPT_VERIFY_STRICTENC` flag: 4de26b111f/src/script/interpreter.cpp (L220)
- A [consensus error](https://github.com/bitcoin/bips/blob/master/bip-0342.mediawiki?plain=1#L93) in Tapscript: 4de26b111f/src/script/interpreter.cpp (L368)
It would be good for readability and testability to have separate errors for both cases, as they are quite distinct (policy vs. consensus, format vs. emptiness).
**This PR adds `SCRIPT_ERR_TAPSCRIPT_EMPTY_PUBKEY` for the consensus error path.**
This change would make our error handling more consistent. We have more granular errors for other pubkey error paths already: `SCRIPT_ERR_WITNESS_PUBKEYTYPE`, `SCRIPT_ERR_DISCOURAGE_UPGRADABLE_PUBKEYTYPE`. We also have separate errors for MINIMAL_IF: `SCRIPT_ERR_MINIMALIF` for the policy error pre-tapscript, and `SCRIPT_ERR_TAPSCRIPT_MINIMALIF` for the consensus error post-tapscript.
Tests:
Added a test case to `script_tests` and ran `build/bin/test_bitcoin --run_test=script_tests --log_level=success`.

"tor" as a network specification was deprecated in 60dc8e4208 in favor
of "onion" and this commit removes it and updates the relevant test.
Co-authored-by: Mara van der Laan <126646+laanwj@users.noreply.github.com>
As pointed out by Sjors in
https://github.com/bitcoin/bitcoin/pull/34003#discussion_r2598844209 and
https://github.com/bitcoin/bitcoin/pull/34003#discussion_r2598858386 the
original intention of having waitNext and waitTipChanged calls in the test was
to ensure that if new blocks were connected or fees were increased *during* the
waits, that the calls would wake up and return.
But the tests were written incorrectly, to generate blocks and transactions
before the wait calls instead of during the calls. So the tests were less
meaningful then they should be.
There was also a similar problem in the interruptWait test. The test was
intended to test the interruptWait method, but it was never actually calling
the method due to a missing await keyword. Instead it was testing that
miniwallet.send_self_transfer would interrupt the wait.
This commit fixes these issues by introducing a wait_and_do() helper function
to start parallel tasks and trigger an action after a wait call is started.
Co-authored-by: Sjors Provoost <sjors@sprovoost.nl>
There are a few things that are incorrect or messy in the interface_ipc.py test.
This commit tries to clean them up:
- isTestChain and isInitialBlockDownload asserts were not checking the results
of those calls, only that calls were, made because they were not checking the
responses' .result member.
- A lot of result accesses like `template.result` `mining.result` were repeated
unnecessarily because variables like `template` and `mining` were assigned
response objects instead of result objects. These variables are now changed
to point directly to results.
- Some coroutine calls were assigned to temporary `wait` before being awaited.
This was unnecessarily confusing and would make code not run in top-down
order.
- `to_dict` calls were being made to check if result variables were unset. This
was inefficient and indirect because it iterates over all fields in response
structs instead of just checking whether the result field is present. The
to_dict calls are now replaced with more direct `_has('result')` calls.
- The `res` variables used to hold various responses did not have descriptive
names. These are replaced with clearer names.

dcd42d6d8f160ae8bc12c152099a6e6473658e30 [test] wallet send 3 generation TRUC (glozow)
e753fadfd01cb8a4a8de3bddc7391481551cca89 [wallet] never try to spend from unconfirmed TRUC that already has ancestors (glozow)
Pull request description:
Addresses https://github.com/bitcoin/bitcoin/issues/33368#issuecomment-3319935660
There is not an explicit check that the to-be-created wallet transaction would be within the {TRUC, normal} ancestor limits. This means that the wallet may create a transaction that violates these limits, but fail to broadcast it in `CommitTransaction`.
This appears to be expected behavior for the normal ancestor limits (and any other situation in which the wallet creates a tx that was rejected by mempool) and AFAIK the transaction will be rebroadcast at some point after the ancestors confirm.
1ed00a0d39/test/functional/wallet_basic.py (L502-L506)
It's a bit complex to address this for the normal ancestor limit, and probably unrealistic for the wallet to check all possible mempool policies in coin selection, but it's quite trivial for TRUC: just skip any unconfirmed UTXOs that have any ancestors. I think it would be much more helpful to the user to say there are insufficient funds.

Use context managers to destroy block templates. Previously, block templates
were not being destroyed before disconnecting because the destroy coroutines
were called but never awaited. It's not necessary to explicitly destroy the
templates since they will get garbage collected asynchronously, but it's good
to destroy them to make the test more predictable, and to make the destroy
calls that are present actually do something.
This change also removes `await waitnext` expressions without changing
behavior, because the previous code was misleading about what order waitNext
calls were executed.
This change is easiest to review ignoring whitespace.

I can reproduce this intermittently via `while ./bld-cmake/test/functional/test_runner.py $(for i in {1..400}; do echo -n "tool_rpcauth "; done) -j 400 ; do true ; done`.
I suspect this is a race where the shutdown starts the close of the network thread while it is starting.
A different exception showing this race can be reproduced via:

It is trivial to reproduce via any test (e.g. `./bld-cmake/test/functional/tool_rpcauth.py`) and shows a similar traceback to the one above:

Pull request description:
Historically, there was an attempt via `test/lint/lint-python-utf8-encoding.py` to enforce explicit UTF8 in every Python IO statement (`open`, `subprocess`, ...). However, the lint check has many problems:
* The check is incomplete and many IO statements lack the explicit UTF8 specification.
* It was added at a time when some systems were not UTF8 by default.
* The check is brittle, as it depends on a fragile regex.
In theory, now that the minimum Python version is 3.10 (since commit 2123c94448ed142e78942421c597a1f264859c48), the check could be replaced by `PYTHONWARNDEFAULTENCODING=1` from https://docs.python.org/3/whatsnew/3.10.html#optional-encodingwarning-and-encoding-locale-option. However, this comes with many other problems:
* All our Python scripts already assume and require UTF8 to be set externally. On almost all modern systems, this is already the default. Some Windows versions do not have UTF8 by default and require `PYTHONUTF8=1` to be set for the tests to run already today (with or without the changes in this pull). Also, the CI and many other Bash scripts force UTF8 via `LC_ALL`. Finally, Python 3.15 will likely enable UTF8 on *all* systems by default, per https://peps.python.org/pep-0686/#abstract.
* So adding UTF8 to every single IO call is redundant, verbose, and confusing, given that it is the expected default.
So fix all issues, by:
* Removing the `test/lint/lint-python-utf8-encoding.py` check.
* Removing the encoding on the individual IO calls.
* Clarifying the existing docs around the existing UTF8 requirement and assumption.
Obviously, every IO call is still free to specify UTF8 or any other encoding explicitly, if there is a documented need for it in the future.

The existing IBD disable was added at a time when CheckForkWarningConditions
did also sophisticated fork detection that could lead to false positives
during IBD (55ed3f14751206fc87f0cbf8cb4e223efacef338).
The fork detection logic doesn't exist anymore
(since fa62304c9760f0de9838e56150008816e7a9bacb), so the IBD check is no
longer necessary.
Displaying the log at startup will help node operators diagnose the
problem better.
Also unify log message and alert warning text, since a long invalid chain
could be due to chainstate corruption or an actual consensus incompatibility
with peers. Previously the log assumed the former and the alert the latter.

Pull request description:
Logging supports severity levels above info via the legacy `LogPrintf`. So use the more appropriate `LogError` or `LogWarning`, where it applies.
This has a few small benefits:
* It often allows to remove the manual and literal "error: ", "Warning:", ... prefixes. Instead the uniform log level formatting is used.
* It is easier to grep or glance for more severe logs, which indicate some kind of alert.
* `LogPrintf` didn't indicate any severity level, but it is an alias for `LogInfo`. So having the log level explicitly spelled out makes it easier to read the code.
* Also, remove the redundant trailing `\n` newline, while touching.
* Also, remove the `__func__` formatting in the log string, which is redundant with `-logsourcelocations`. Instead, use a unique log string for each location.

As suggested in the main cluster mempool PR (https://github.com/bitcoin/bitcoin/pull/28676#pullrequestreview-3177119367), I've pulled out some of the non-essential optimizations and cleanups into this separate PR.

Also improve test coverage for removeForReorg by creating a scenario where
there are in-mempool descendants that are only invalidated due to an in-mempool
parent no longer spending a mature coin.
Empty public keys in tapscript are rejected by consensus rules, independent of SCRIPT_VERIFY_STRICTENC. Add SCRIPT_ERR_TAPSCRIPT_EMPTY_PUBKEY to distinguish this from STRICTENC policy failures currently reported as SCRIPT_ERR_PUBKEYTYPE.
All touched Python scripts already assume and require UTF8, so manually
specifying encoding or decoding for functions in the subprocess module
is redundant to just using text=True, which exists since Python 3.7
Historically, the headers have been bumped some time after a file has
been touched. Do it now to avoid having to touch them again in the
future for that reason.
-BEGIN VERIFY SCRIPT-
sed -i --regexp-extended 's;( 20[0-2][0-9])(-20[0-2][0-9])? The Bitcoin Core developers;\1-present The Bitcoin Core developers;g' $( git show --pretty="" --name-only HEAD~0 )
-END VERIFY SCRIPT-
The encoding arg is confusing, because it is not applied consistently
for all IO.
Also, it is useless, as the majority of files are ASCII encoded, which
are fine to encode and decode with any mode.
Moreover, UTF-8 is already required for most scripts to work properly,
so setting the encoding twice is redundant.
So remove the encoding from most IO. It would be fine to remove from all
IO, however I kept it for two files:
* contrib/asmap/asmap-tool.py: This specifically looks for utf-8
encoding errors, so it makes sense to sepecify the utf-8 encoding
explicitly.
* test/functional/test_framework/test_node.py: Reading the debug log in
text mode specifically counts the utf-8 characters (not bytes), so it
makes sense to specify the utf-8 encoding explicitly.
The check was incomplete and brittle. A better check would be to enable
`PYTHONWARNDEFAULTENCODING=1`
https://docs.python.org/3/whatsnew/3.10.html#optional-encodingwarning-and-encoding-locale-option
However, it is unclear what the goal of adding explicit encodings
everywhere is, given that:
* Most modern systems already have UTF-8 enabled by default, except for
Windows.
* Python 3.15 will likely enable it globally by default, according to
https://peps.python.org/pep-0686/#abstract
* Adding the explicit encodings will bloat all code for no benefit.
So remove the lint check and drop all redundant encoding= kwargs.
All encoding= that are set for a reason, are kept.
It will likely be the default for all systems, starting with Python
3.15, according to https://peps.python.org/pep-0686/#abstract.
It is hard to find a system other than Windows that has it not enabled
today. Nonetheless, Bitcoin Core requires UTF-8 in scripts and normally
enforces it via LC_ALL=C.UTF-8 or PYTHONUTF8=1.
Bash is discouraged, and there was never a need to write locale
dependent Bash.
So remove the option and clarify that the LC_ALL settings enable UTF-8
mode in Python.
8343a9ffcc752f77eb2248315d10b6dff4a5c98b test: add `-alertnotify` test for large work invalid chain warning (Sebastian Falbesoner)
Pull request description:
This PR adds missing test coverage for the `LARGE_WORK_INVALID_CHAIN` fork warning, checked with the `-alertnotify` option:
ead849c9f1/src/validation.cpp (L2033-L2040)
Found that this is missing during review of #32587. The test works by first creating a bunch of invalid blocks, that are first announced by headers and then submitted fully in reverse (invalid tip first), in order to set `m_best_invalid` to that value, finally leading to the best chain / invalid chain gap of >= 6 blocks. I'd be curious if there are other (more realistic?) ways to test this. One simple alternative is just to call `invalidateblock` twice (once at the tip, once at the base of the invalid chain).
Note that the written warning doesn't include the exclamation mark, as it is removed via `SanitizeString` in the `AlertNotify` function.

Pull request description:
[Reopening #28676 here as a new PR, because GitHub is slow to load the page making it hard to scroll through and see comments. Also, that PR was originally opened with a prototype implementation which has changed significantly with the introduction of `TxGraph`.]
This is an implementation of the [cluster mempool proposal](https://delvingbitcoin.org/t/an-overview-of-the-cluster-mempool-proposal/393).
This branch implements the following observable behavior changes:
- Maintains a partitioning of the mempool into connected clusters (via the `txgraph` class), which are limited in vsize to 101 kvB by default, and limited in count to 64 by default.
- Each cluster is sorted ("linearized") to try to optimize for selecting highest-feerate-subsets of a cluster first
- Transaction selection for mining is updated to use the cluster linearizations, selecting highest feerate "chunks" first for inclusion in a block template.
- Mempool eviction is updated to use the cluster linearizations, selecting lowest feerate "chunks" first for removal.
- The RBF rules are updated to: (a) drop the requirement that no new inputs are introduced; (b) change the feerate requirement to instead check that the feerate diagram of the mempool will strictly improve; (c) replace the direct conflicts limit with a directly-conflicting-clusters limit.
- The CPFP carveout rule is eliminated (it doesn't make sense in a cluster-limited mempool)
- The ancestor and descendant limits are no longer enforced.
- New cluster count/cluster vsize limits are now enforced instead.
- Transaction relay now uses chunk feerate comparisons to determine the order that newly received transactions are announced to peers.
Additionally, the cached ancestor and descendant data are dropped from the mempool, along with the multi_index indices that were maintained to sort the mempool by ancestor and descendant feerates. For compatibility (eg with wallet behavior or RPCs exposing this), this information is now calculated dynamically instead.

Previously we would sanity check the -maxmempool configuration based on a
multiple of the descendant size limit, but with cluster mempool the maximum
evicted size is now the cluster size limit, so use that instead.
Also allow -maxmempool=0 in general (and not just if
-limitdescendantsize/-limitclustersize is set to 0).

f6ec3519a330e5c3899a4d9f7d26b7980a597b41 init: Require explicit -asmap filename (Ryan Ofsky)
Pull request description:
Currently, if `-asmap` is specified without a filename bitcoind tries to load `ip_asn.map` data file.
This change now requires `-asmap=ip_asn.map` or another filename to be specified explicitly.
The change is intended to make behavior of the option explicit and avoid confusion reported https://github.com/bitcoin/bitcoin/issues/33386 where documentation specifies a default file which is not actually loaded by default. It was originally implemented in
https://github.com/bitcoin/bitcoin/pull/33631#issuecomment-3410302383 and various alternatives are discussed there.
