2024-08-08Reduce cache lookups in CCoinsViewCache::FetchCoinLőrinc
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.
2024-08-05Add linked-list test to CCoinsViewCache::SanityCheckPieter Wuille
2024-08-05coins: move Sync logic to CoinsViewCacheCursorAndrew Toth
Erase spent cache entries and clear flags of unspent entries inside the BatchWrite loop, instead of an additional loop after BatchWrite. Co-Authored-By: Pieter Wuille <pieter@wuille.net>
2024-08-05coins: pass linked list of flagged entries to BatchWriteAndrew Toth
BatchWrite now iterates through the linked list of flagged entries instead of the entire coinsCache map. Co-Authored-By: l0rinc <pap.lorinc@gmail.com>
2024-08-02refactor: require self and sentinel parameters for AddFlagsAndrew Toth
No behavior change. Prepares for adding the CoinsCachePairs to a linked list when flagged.
2024-08-01refactor: disallow setting flags in CCoinsCacheEntry constructorsAndrew Toth
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. Co-Authored-By: Martin Leitner-Ankerl <martin.ankerl@gmail.com>
2024-08-01refactor: encapsulate flags setting with AddFlags and ClearFlagsAndrew Toth
No behavior change. This prepares moving the cache entry flags field to private access.

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.

2023-03-23Use PoolAllocator for CCoinsMapMartin Leitner-Ankerl
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.
2023-03-23Call ReallocateCache() on each Flush()Martin Leitner-Ankerl
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().

2023-01-20coins: add Sync() method to allow flush without cacheCoins dropJames O'Beirne
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. Co-authored-by: Suhas Daftuar <sdaftuar@gmail.com>

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.

2017-07-14Remove confusing MAX_BLOCK_BASE_SIZE.Gregory Maxwell
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.

2017-06-26Simplify return values of GetCoin/HaveCoin(InCache)Pieter Wuille
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.
