acbea66589 rest: clean-up for `mempool` endpoints (brunoerg)
Pull request description:
The functions `rest_mempool_info` and `rest_mempool_contents` are similar, the only difference between them is:
`rest_mempool_info` uses `MempoolInfoToJSON` to get the mempool informations and `rest_mempool_contents` uses `MempoolToJSON`, for this reason this PR creates a new function to handle it and reduce duplicated code.
Also,
1. Rename `strURIPart` to `str_uri_part`.
2. Rename `strJSON` to `str_json`.

a23cca56c0 refactor: Replace BResult with util::Result (Ryan Ofsky)
Pull request description:
Rename `BResult` class to `util::Result` and update the class interface to be more compatible with `std::optional` and with a full-featured result class implemented in https://github.com/bitcoin/bitcoin/pull/25665. Motivation for this change is to update existing `BResult` usages now so they don't have to change later when more features are added in https://github.com/bitcoin/bitcoin/pull/25665.
This change makes the following improvements originally implemented in https://github.com/bitcoin/bitcoin/pull/25665:
- More explicit API. Drops potentially misleading `BResult` constructor that treats any bilingual string argument as an error. Adds `util::Error` constructor so it is never ambiguous when a result is being assigned an error or non-error value.
- Better type compatibility. Supports `util::Result<bilingual_str>` return values to hold translated messages which are not errors.
- More standard and consistent API. `util::Result` supports most of the same operators and methods as `std::optional`. `BResult` had a less familiar interface with `HasRes`/`GetObj`/`ReleaseObj` methods. The Result/Res/Obj naming was also not internally consistent.
- Better code organization. Puts `src/util/` code in the `util::` namespace so naming reflects code organization and it is obvious where the class is coming from. Drops "B" from name because it is undocumented what it stands for (bilingual?)
- Has unit tests.

fadd8b2676 addrman: Use system time instead of adjusted network time (MarcoFalke)
Pull request description:
This changes addrman to use system time for address relay instead of the network adjusted time.
This is an improvement, because network time has multiple issues:
* It is non-monotonic, even if the system time is monotonic.
* It may be wrong, even if the system time is correct.
* It may be wrong, if the system time is wrong. For example, when the node has limited number of connections (`4`), or the system time is wrong by too much (more than +-70 minutes), or the system time only got wrong after timedata collected more than half of the entries while the time was correct, ...)
This may slightly degrade addr relay for nodes where timedata successfully adjusted the time. Addr relay can already deal with minor offsets of up to 10 minutes. Offsets larger than this should still allow addr relay and not result in a DoS.

This command iterates over the inputs and outputs of the given transactions, and tallies up the balance change for the given wallet. This can be useful e.g. when verifying that a coin join like transaction doesn't contain unexpected inputs that the wallet will then sign for unintentionally.

Our RBF policy is different from the rules specified in BIP125. For
example, the BIP does not mention Rule 6, and our Rule 4 uses the
(configurable) incremental relay feerate (distinct from the
minimum relay feerate). Those interested in our policy should refer to
doc/policy/mempool-replacements.md instead. These rules may also
continue to diverge with package RBF and other RBF improvements. Keep
references to the BIP125 signaling wrt sequence numbers, since that is
still correct and widely used. It is helpful to refer to this as "BIP125
signaling" since it is unambiguous and succint, especially if we have
multiple ways to signal replaceability in the future.
The rule numbers in doc/policy/mempool-replacements.md correspond
largely to those of BIP 125, so we can still refer to them like "Rule 5."

For some reason, the primary consumer of getWalletTxs requires the
transactions to be in hash order when it is processing them. std::map
will iterate in hash order so the transactions end up in that order when
placed into the vector. To ensure this order when mapWallet is no longer
ordered, the vector is replaced with a set which will maintain the hash
order.
In order to avoid constantly re-deriving the same keys in
DescriptorScriptPubKeyMan, cache the SigningProviders generated inside
of GetSigningProvider.
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.
This fixes an potential overflow which existed prior to this patchset.
If CuckooCache::cache<Element, Hash>::setup_bytes is called with a
`size_t bytes` which, when divided by sizeof(Element), does not fit into
an uint32_t, the implicit conversion to uint32_t in the call to setup
will result in an overflow.
At least on x86_64, this overflow is possible:
static_assert(std::numeric_limits<size_t>::max() / 32 <= std::numeric_limits<uint32_t>::max());
static_assert(std::numeric_limits<size_t>::max() / 4 <= std::numeric_limits<uint32_t>::max());
This commit detects such cases and signals to callers that the `size_t
bytes` input is too large.
1. -maxsigcachesize is a DEBUG_ONLY option
2. Almost 7 years has passed since its semantics change in
830e3f3d02 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.
In src/test/fuzz/script_sigcache.cpp, we should really be setting up a
full working BasicTestingSetup. The initialize_ function is only run
once anyway.
In src/test/txvalidationcache_tests.cpp, the Dersig100Setup inherits
from BasicTestingSetup, which should have already set up a global script
execution cache without the need to explicitly call
InitScriptExecutionCache.
Our RBF policy is different from the rules specified in BIP125 (refer to
doc/policy/mempool-replacements.md instead), and will continue to
diverge with package RBF. Keep references to BIP125 sequence number,
since that is still useful and correct.

9e04cfaa76 test: add coverage for wallet inconsistent state during sync (furszy)
77de5c693f wallet: guard and alert about a wallet invalid state during chain sync (furszy)
Pull request description:
Follow-up work to my comment in #25239.
Guarding and alerting the user about a wallet invalid state during chain synchronization.
#### Explanation
if the `AddToWallet` tx write fails, the method returns a wtx `nullptr` without removing the recently added transaction from the wallet's map.
Which makes that `AddToWalletIfInvolvingMe` return false (even when the tx is on the wallet's map already), --> which makes `SyncTransaction` skip the `MarkInputsDirty` call --> which leads to a wallet invalid state where the inputs of this new transaction are not marked dirty, while the transaction that spends them still exist on the in-memory wallet tx map.
Plus, as we only store the arriving transaction inside `AddToWalletIfInvolvingMe` when we synchronize/scan block/s from the chain and nowhere else, it makes sense to treat the transaction db write error as a runtime error to notify the user about the problem. Otherwise, the user will lose all the not stored transactions after a wallet shutdown (without be able to recover them automatically on the next startup because the chain sync would be above the block where the txs arrived).
Note:
On purpose, the first commit adds test coverage for it. Showing how the wallet can end up in an invalid state. The second commit corrects it with the proposed solution.
