If it is replaced with a chain limit value calculator, that can be called once and reused, and is generally more flexible (see e.g. #12257). Update: this PR now corrects usage of max ancestors / max descendants, including calculating the correct max descendant value, as advertised for the two limits. ~~This change also makes `nMaxAncestors` signed, as the replacement method will return `-1` for "not in the mempool", which is different from "0", which means "no ancestors/descendants in mempool".~~ ~~This is a subset of #12257.~~ Tree-SHA512: aa59c849360542362b3126c0e29d44d3d58f11898e277d38c034dc4b86a5b4500f77ac61767599ce878c876b5c446fec9c02699797eb2fa41e530ec863a00cf9

2018-06-11mempool: Fix max descendants checkKarl-Johan Alm
The chain limits check for max descendants would check the descendants of the transaction itself even though the description for -limitdescendantcount says 'any ancestor'. This commit corrects the descendant count check by finding the top parent transaction in the mempool and comparing against that.
2018-06-11mempool: Add explicit max_descendantsKarl-Johan Alm
TransactionWithinChainLimits would take a 'limit' and check it against ascendants and descendants. This is changed to take an explicit max ancestors and max descendants value, and to test the corresponding value against its corresponding max.

b55555d rpc: Add testmempoolaccept (MarcoFalke) Pull request description: To check if a single raw transaction makes it into the current transaction pool, one had to call `sendrawtransaction`. However, on success, this adds the transaction to the mempool with no easy way to undo. The call `testmempoolaccept` is introduced to provide a way to solely check the result without changing the mempool state.

2017-08-28Remove redundant explicitly defined copy ctorsDan Raviv
CFeeRate and CTxMemPoolEntry have explicitly defined copy ctors which has the same functionality as the implicit default copy ctors which would have been generated otherwise. Besides being redundant, it violates the rule of three (see https://en.wikipedia.org/wiki/Rule_of_three_(C%2B%2B_programming) ). (Of course, the rule of three doesn't -really- cause a resource management issue here, but the reason for that is exactly that there is no need for an explicit copy ctor in the first place since no resources are being managed). CFeeRate has an explicitly defined copy ctor which has the same functionality as the implicit default copy ctor which would h ave been generated otherwise.

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.

2017-06-05Remove useless mapNextTx lookup in CTxMemPool::TrimToSize.Matt Corallo
Prior to per-utxo CCoins, we checked that no other in-mempool tx spent any of the given transaction's outputs, as we don't want to uncache that entire tx in such a case. However, we now are checking only that there exists no other mempool spends of the same output, which should clearly be impossible after we removed the transaction which was spending said output (barring massive mempool inconsistency). Thanks to @sdaftuar for the suggestion.

2017-06-01Switch CCoinsView and chainstate db from per-txid to per-txoutPieter Wuille
This patch makes several related changes: * Changes the CCoinsView virtual methods (GetCoins, HaveCoins, ...) to be COutPoint/Coin-based rather than txid/CCoins-based. * Changes the chainstate db to a new incompatible format that is also COutPoint/Coin based. * Implements reconstruction code for hash_serialized_2. * Adapts the coins_tests unit tests (thanks to Russell Yanofsky). A side effect of the new CCoinsView model is that we can no longer use the (unreliable) test for transaction outputs in the UTXO set to determine whether we already have a particular transaction.

2017-04-01Change LogAcceptCategory to use uint32_t rather than sets of strings.Gregory Maxwell
This changes the logging categories to boolean flags instead of strings. This simplifies the acceptance testing by avoiding accessing a scoped static thread local pointer to a thread local set of strings. It eliminates the only use of boost::thread_specific_ptr outside of lockorder debugging. This change allows log entries to be directed to multiple categories and makes it easy to change the logging flags at runtime (e.g. via an RPC, though that isn't done by this commit.) It also eliminates the fDebug global. Configuration of unknown logging categories now produces a warning.
