Move its ownership to the ChainstateManager class.
Next to simplifying usage of the kernel library by no longer requiring
manual setup of the cache prior to using validation code, it also slims
down the amount of memory allocated by BasicTestingSetup.
Use this opportunity to make SignatureCache RAII styled

This is done in preparation for the following commit. Also rename it to
SignatureCache.

Instead clamp it to uint32::max if it exceeds it.

...also move the 0-clamping logic to ApplyArgsManOptions, where it
belongs.

Also:
- Make DEFAULT_MAX_SIG_CACHE_SIZE into constexpr
DEFAULT_MAX_SIG_CACHE_BYTES to utilize the compile-time integer
arithmetic overflow checking available to constexpr.
- Fix comment (MiB instead of MB) for DEFAULT_MAX_SIG_CACHE_BYTES.
- Pass in max_size_bytes parameter to InitS*Cache(), modify log line to
no longer allude to maxsigcachesize being split evenly between the two
validation caches.
- Fix possible integer truncation and add a comment.
[META] I've kept the integer types as int64_t in order to not introduce
unintended behaviour changes, in the next commit we will make
them size_t.

1. -maxsigcachesize is a DEBUG_ONLY option
2. Almost 7 years has passed since its semantics change in
830e3f3d027ba5c8121eed0f6a9ce99961352572 from "number of entries" to
"number of mebibytes"
3. A std::new_handler was added to the codebase after the original PR
which introduced this limit, which will terminate immediately instead
of causing trouble by being caught somewhere unexpected.
|

Returning the approximate total size eliminates the need for
InitS*Cache() to do nElems*sizeof(uint256). The cuckoocache has a better
idea of this information.

Remove the implicit MissingDataBehavior::ASSERT_FAIL in the
*TransationSignatureChecker constructors, and instead specify
it explicit in all call sites:
* Test code uses ASSERT_FAIL
* Validation uses ASSERT_FAIL (through CachingTransactionSignatureChecker)
(including signet)
* libconsensus uses FAIL, matching the existing behavior of the
non-amount API (and the extended required data for taproot validation
is not available yet)
* Signing code uses FAIL

95e61c1cf2a91d041c8025306ba36f0ea2806894 Move Hashers to util/hasher.{cpp/h} (Andrew Chow)
Pull request description:
There are existing `SaltedOutPointHasher` and `SaltedTxidHasher` classes used for `std::unordered_map` and `std::unordered_set` that could be useful in other places in the codebase. So we these to their own `saltedhash.{cpp/h}` file. An existing `KeyIDHasher` is moved there too. Additionally, `ScriptIDHasher`, `SaltedPubkeyHasher`, and `SaltedScriptHasher` are added so that they can be used in future work.
`KeyIDHasher` and `ScriptIDHasher` are not salted so that equality comparisons of maps and sets keyed by `CKeyID` and `CScriptID` will actually work.
Split from #19602 (and a few other PRs/branches I have).

Move the hashers that we use for hash tables to a common place.
Moved hashers:
- SaltedTxidHasher
- SaltedOutpointHasher
- FilterHeaderHasher
- SignatureCacheHasher
- BlockHasher

This enables the schnorrsig module in libsecp256k1, adds the relevant types
and functions to src/pubkey, as well as in higher-level `SignatureChecker`
classes. The (verification side of the) BIP340 test vectors is also added.
|
|
In preparation for adding Schnorr versions of `CheckSig`, `VerifySignature`, and
`ComputeEntry`, give them an ECDSA specific name.

This moves the SignatureCacheHasher to the sigcache header, out of the anonymous
namespace, so that the tests can import it.

- If the -maxsigcachesize parameter is set to zero, setup a minimum sized
sigcache (2 elements) rather than segfaulting.
- Handle maxsigcachesize being negative
- Handle maxsigcachesize being too large
