Enhanced efficiency and readability of CCoinsViewCache::FetchCoin by replacing separate find() and emplace() calls with a single try_emplace(), reducing map lookups and potential insertions.

Erase spent cache entries and clear flags of unspent
entries inside the BatchWrite loop, instead of an
additional loop after BatchWrite.

BatchWrite now iterates through the linked
list of flagged entries instead of the entire
coinsCache map.

No behavior change. Prepares for adding the CoinsCachePairs to
a linked list when flagged.
|
|
No behavior change because any entries that are added in EmplaceCoinInternalDANGER
have DIRTY assigned to them after, and if they
are not inserted then they will not be
modified as before.
This prepares moving the cache entry
flags field to private access.

7fe537f7a48675b1d25542bee6f390d665547580 Implement CCoinsViewErrorCatcher::HaveCoin (Aurèle Oulès)
Pull request description:
Attempt to fix #26112.
As suggested by sipa in https://github.com/bitcoin/bitcoin/issues/26112#issuecomment-1249683401:
> CCoinsViewErrorCatcher, the wrapper class used around CCoinsViewDB that's supposed to detect these problems and forcefully exit the application, has an override for GetCoins. But in CheckTxInputs, HaveInputs is first invoked, which on its turn calls HaveCoin. HaveCoin is implemented in CCoinsViewDB, but not in CCoinsViewErrorCatcher, and thus the disk read exception escapes.
> A solution may be to just add an override for HaveCoin in CCoinsViewErrorCatcher.
I implemented `CCoinsViewErrorCatcher::HaveCoin` and also added a periodic disk space check that shutdowns the node if there is not enough space left on disk, the minimum here is 50MB.
For reviewers, it's possible to saturate disk space to test the PR by creating large files with `fallocate -l 50G test.bin`

In my benchmarks, using this pool allocator for CCoinsMap gives about
20% faster `-reindex-chainstate` with -dbcache=5000 with practically the
same memory usage. The change in max RSS changed was 0.3%.
The `validation_flush_tests` tests need to be updated because
memory allocation is now done in large pools instead of one node at a
time, so the limits need to be updated accordingly.
|
|
This frees up all associated memory with the map, not only the nodes.
This is necessary in preparation for using the PoolAllocator for
CCoinsMap, which does not actually free any memory on clear().

In certain circumstances, we may want to flush to disk without
emptying `cacheCoins`, which affects performance. UTXO snapshot
activation is one such case.
This method is currently unused and this commit does not
change any behavior.
Incorporates feedback from John Newbery.

unnecessarily copying objects and enable two clang-tidy checks

I added const references to some variables to avoid unnecessarily copying objects.
Also added two clang-tidy checks : [performance-for-range-copy](https://releases.llvm.org/11.1.0/tools/clang/tools/extra/docs/clang-tidy/checks/performance-for-range-copy.html) and [performance-unnecessary-copy-initialization](https://releases.llvm.org/12.0.0/tools/clang/tools/extra/docs/clang-tidy/checks/performance-unnecessary-copy-initialization.html).

This avoids initializing variables with the copy-constructor of a
non-trivially copyable type.

Specifically with CCoinsViewDB, if a raw cursor is allocated and
not freed, a cryptic leveldb assertion failure occurs on
CCoinsViewDB destruction.

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
|
|
Also adds CCoinsViewCache::ReallocateCache() to attempt to free
memory that the cacheCoins's allocator may be hanging onto when
downsizing the cache.
Adds `CChainState::m_coins{tip,db}_cache_size_bytes` data members
so that we can reference cache size on a per-chainstate basis for
flushing.
|
|
|
|
And other general comment improvements for adding coins.
|

Remove references to 'pruned' coins, which don't exist since the move
to per-txout coins db.

and into coins.cpp. This move is necessary so that we can later include a

std::unordered_map::erase( const_iterator pos ) returns an iterator to the element following the removed one. Use that to optimize (probably minor-performance-wise, and definitely code-structure-wise) the implementation of CCoinsViewCache::BatchWrite().
|
|
|

Some people keep thinking that MAX_BLOCK_BASE_SIZE is a separate
size limit from the weight limit when it fact it is superfluous,
and used in early tests before the witness data has been
validated or just to compute worst case sizes. The size checks
that use it would not behave any differently consensus wise
if they were eliminated completely.
Its correct value is not independently settable but is a function
of the weight limit and weight formula.
This patch just eliminates it and uses the scale factor as
required to compute the worse case constants.
It also moves the weight factor out of primitives into consensus,
which is a more logical place for it.

This removes the possibility for GetCoin/HaveCoin/HaveCoinInCache to return
true while the respective coin is spent. By doing it across all calls, some
extra checks can be eliminated.
coins_tests is modified to call HaveCoin sometimes before and sometimes
after AccessCoin. A further change is needed because the semantics for
GetCoin slightly changed, causing a pruned entry in the parent cache to not
be pulled into the child in FetchCoin.
