b0c774b48a3198584e61429ef053844bdde2f9ae Add new mempool benchmarks for a complex pool (Jeremy Rubin)
Pull request description:
This PR is related to #17268.
It adds a mempool stress test which makes a really big complicated tx graph, and then, similar to mempool_eviction test, trims the size.
The test setup is to make 100 original transactions with Rand(10)+2 outputs each.
Then, 800 times:
we create a new transaction with Rand(10) + 1 parents that are randomly sampled from all existing transactions (with unspent outputs). From each such parent, we then select Rand(remaining outputs) +1 50% of the time, or 1 outputs 50% of the time.
Then, we trim the size to 3/4. Then we trim it to just a single transaction.
This creates, hopefully, a big bundle of transactions with lots of complex structure, that should really put a strain on the mempool graph algorithms.
This ends up testing both the descendant and ancestor tracking.
I don't love that the test is "unstable". That is, in order to compare this test to another, you really can't modify any of the internal state because it will have a different order of invocations of the deterministic randomness. However, it certainly suffices for comparing branches.

8734c856f85cb506fa97596383dd7e7b9edd7e03 Replace the LogPrint function with a macro (Jeffrey Czyz)
Pull request description:
Calling `LogPrint` with a category that is not enabled results in
evaluating the remaining function arguments, which may be arbitrarily
complex (and possibly expensive) expressions. Defining `LogPrint` as a
macro prevents this unnecessary expression evaluation.
This is a partial revert of #14209. The decision to revert is discussed
in #16688, which adds verbose logging for validation event notification.

ECCVerifyHandle dependency

Pull request description:
The fuzzers `eval_script` and `script_flags` require holding `ECCVerifyHandle`.
This is a follow-up to #17235 which accidentally broke those two fuzzers.
Sorry about the temporary breakage my fuzzing friends: it took a while to fuzz before reaching these code paths. That's why this wasn't immediately caught. Sorry.

Instead of keeping pindexBestHeader set to the best header we've
ever seen, reset it back to our validated tip if we find an ancestor
of it turns out to be invalid. While the name is now a bit confusing,
this matches much better with how it is used in practice, see below.
Further, this opens up more use-cases for it in the future, namely
aggressively searching for new peers in case we have discovered
(possibly via some covert channel) headers which we do not know to be
invalid, but which we cannot find block data for.
Places pindexBestHeader is used:
* Various GUI displays of the best header and getblockchaininfo["headers"],
I don't think changing this is bad, and if anything this is less confusing
in the presence of an invalid block.
* IsCurrentForFeeEstimation(): If anything I think ensuring pindexBestHeader
isn't some crazy invalid chain is better than the alternative, even in the
case where you are rejecting the current chain due to hardware error (since
hopefully in that case you won't get any new blocks anyway).
* ConnectBlock assumevalid checks: We use pindexBestHeader to check that the
block we're connecting leads to something with nMinimumChainWork (preventing
a user-set assumevalid from having bogus work) and that the block we're
connecting leads to pindexBestHeader (I'm not too worried about this one -
it's nice to "disable" assumevalid if we have a long invalid headers chain,
but I don't see it as a critical protection).
* BlockRequestAllowed() uses pindexBestHeader as its target to ensure the
requested block is within a month of the "current chain". I don't think this
is a meaningful difference, if we're rejecting the current tip we're
trivially fingerprintable anyway, and if the chain really does have a bunch
of invalid crap near the tip, using the best not-invalid header is likely a
better criteria.
* ProcessGetBlockData uses pindexBestHeader as the "current chain" definition
of whether a block request is "historical" for the purpose of bandwidth
limiting. Similarly, I don't see why this is a meaningful change.
* We use pindexBestHeader for requesting missing headers on receipt of a
headers/compact block message or block inv as well as for initial getheaders.
I think this is definitely wrong, using the best not-invalid header for such
requests is much better.
* We use pindexBestHeader to define the "current chain" for deciding when
we're close to done with initial headers sync. I don't think this is a
meaningful change.
* We use pindexBestHeader to decide if initial headers sync has timed out. If
we're rejecting the chain due to hardware error this may result in
additional cases where we ban a peer, but this is already true, so I think
its fine.

Pull request description:
Carries out some remaining tidy-ups remaining after PR 15141:
- split ValidationState into TxValidationState and BlockValidationState (commit from ajtowns)
- various minor code style tidy-ups to the ValidationState class
- remove the useless `ret` parameter from `ValidationState::Invalid()`
- remove the now unused `first_invalid` parameter from `ProcessNewBlockHeaders()`
- remove the `fMissingInputs` parameter from `AcceptToMemoryPool()`, and deal with missing inputs the same way as other errors by using the `TxValidationState` object.
Tip for reviewers (thanks ryanofsky!): The first commit ("[validation] Add CValidationState subclasses" ) is huge and can be easier to start reviewing if you revert the rote, mechanical changes:
Substitute the commit hash of commit "[validation] Add CValidationState subclasses" for <CommitHash> in the commands below.
```sh
git checkout <CommitHash>
git grep -l ValidationState | xargs sed -i 's/BlockValidationState\|TxValidationState/CValidationState/g'
git grep -l ValidationResult | xargs sed -i 's/BlockValidationResult\|TxValidationResult/ValidationInvalidReason/g'
git grep -l MaybePunish | xargs sed -i 's/MaybePunishNode\(ForBlock\|ForTx\)/MaybePunishNode/g'
git diff HEAD^
```
After that it's possible to easily see the mechanical changes with:
```sh
git log -p -n1 -U0 --word-diff-regex=. <CommitHash>
```

301bd41a2e6765b185bd55f4c541f9e27aeea29d scripted-diff: Rename InitInterfaces to NodeContext (Russell Yanofsky)
Pull request description:
This change is mainly a naming / organization change intended to simplify #10102. It:
- Renames struct InitInterfaces to struct NodeContext and moves it from
src/init.h to src/node/context.h. This is a cosmetic change intended to make
the point of the struct more obvious.
- Gets rid of BanMan and ConnMan globals making them NodeContext members
instead. Getting rid of these globals has been talked about in past as a way
to implement testing and simulations. Making them NodeContext members is a
way of keeping them accessible without the globals.
- Splits g_rpc_interfaces global into g_rpc_node and g_rpc_chain globals. This
better separates node and wallet rpc methods. Node RPC methods should have
access NodeContext, while wallet RPC methods should only have indirect access
to node functionality via interfaces::Chain.
- Adds NodeContext& references to interfaces::Chain class and the
interfaces::MakeChain() function. This is needed to access ConnMan and BanMan
instances without the globals.
- Gets rid of redundant Node and Chain instances in Qt tests. This is
needed due to the previous MakeChain change, and also makes test setup a
little more straightforward. More cleanup could be done in the future, but it
will require deduplication of bitcoind, bitcoin-qt, and TestingSetup init
code.

c1c6c410a66996b2d60d5172189b5a5ec8100842 test: add reason checks for non-standard txs in test_IsStandard (Sebastian Falbesoner)
Pull request description:
While taking a look at #17272 I noticed that for some reason the unit test `test_IsStandard` (which was not adapted to the policy change in the referenced PR commits) didn't fail as expected:
https://github.com/bitcoin/bitcoin/blob/6a97e8a060f7632bbaee27d3de8035dc6ebe3895/src/test/transaction_tests.cpp#L758-L762
It turned out that `IsStandardTx()` returned `"dust"` as rejection reason (instead of the expected `"multi-op-return"`), leading to the conclusion that https://github.com/bitcoin/bitcoin/pull/17272/commits/5fe6f052bd37a16b2849e05f5cf18d7e194bc705 erroneously performs the `IsDust()` check also for TX_NULL_DATA transactions. To avoid cases like this in the future, this PR makes the unit test `test_IsStandard` more strict by also checking for the concrete reason after each occurence of `IsStandardTx()` returning false.

Handle this failure in the same way as all other failures: call Invalid()
with the reasons for the failure.
|
|
No callers use the returned value in first_invalid. Remove it from the
function signature and don't set it in the function.
|
|
ValidationState::Invalid() takes a parameter `ret` which is returned to
the caller. All call sites set this to false. Remove the `ret` parameter
and just return false always.
|
|
This is in preparation for the next commit, which removes the useless
`ret` parameter from ValidationState::Invalid().
error() is simply a convenience wrapper that calls LogPrintf and returns
false. Call LogPrintf explicitly and substitute the error() call for a
false bool literal.
|
|
Minor style fixups and comment updates.
This is purely a style change. There is no change in behavior.
|
|
Split CValidationState into TxValidationState and BlockValidationState
to store validation results for transactions and blocks respectively.
|
|
|
|
These value are useful to know the current progress of
initial sync, or of catching up.
