2017-04-05Bugfix: ancestor modifed fees were incorrect for descendantsSuhas Daftuar
If prioritisetransaction was called for a tx with in-mempool descendants, the modified ancestor fee values for those descendants was incorrect. Github-Pull: #10144 Rebased-From: 9bef02e36525d0eed4e2e31678b3ff04bbb0b8cb

Add notification signals to make it possible to subscribe to mempool changes: - NotifyEntryAdded(CTransactionRef)> - NotifyEntryRemoved(CTransactionRef, MemPoolRemovalReason)> Also add a mempool removal reason enumeration, which is passed to the removed notification based on why the transaction was removed from the mempool.

2017-01-04Always update fee estimates on new blocks.Alex Morcos
All decisions about whether the transactions are valid data points are made at the time the transaction arrives. Updating on blocks all the time will now cause stale fee estimates to decay quickly when we restart a node.

2017-01-04Remove member variable hadNoDependencies from CTxMemPoolEntryAlex Morcos
Fee estimation can just check its own mapMemPoolTxs to determine the same information. Note that now fee estimation for block processing must happen before those transactions are removed, but this shoudl be a speedup.

2016-10-17Kill insecure_random and associated global stateWladimir J. van der Laan
There are only a few uses of `insecure_random` outside the tests. This PR replaces uses of insecure_random (and its accompanying global state) in the core code with an FastRandomContext that is automatically seeded on creation. This is meant to be used for inner loops. The FastRandomContext can be in the outer scope, or the class itself, then rand32() is used inside the loop. Useful e.g. for pushing addresses in CNode or the fee rounding, or randomization for coin selection. As a context is created per purpose, thus it gets rid of cross-thread unprotected shared usage of a single set of globals, this should also get rid of the potential race conditions. - I'd say TxMempool::check is not called enough to warrant using a special fast random context, this is switched to GetRand() (open for discussion...) - The use of `insecure_rand` in ConnectThroughProxy has been replaced by an atomic integer counter. The only goal here is to have a different credentials pair for each connection to go on a different Tor circuit, it does not need to be random nor unpredictable. - To avoid having a FastRandomContext on every CNode, the context is passed into PushAddress as appropriate. There remains an insecure_random for test usage in `test_random.h`.

9805f4a mapNextTx: use pointer as key, simplify value (Kaz Wesley)
2016-06-02mapNextTx: use pointer as key, simplify valueKaz Wesley
Saves about 10% of application memory usage once the mempool warms up. Since the mempool is DynamicUsage-regulated, this will translate to a larger mempool in the same amount of space. Map value type: eliminate the vin index; no users of the map need to know which input of the transaction is spending the prevout. Map key type: replace the COutPoint with a pointer to a COutPoint. A COutPoint is 36 bytes, but each COutPoint is accessible from the same map entry's value. A trivial DereferencingComparator functor allows indirect map keys, but the resulting syntax is misleading: `map.find(&outpoint)`. Implement an indirectmap that acts as a wrapper to a map that uses a DereferencingComparator, supporting a syntax that accurately reflect the container's semantics: inserts and iterators use pointers since they store pointers and need them to remain constant and dereferenceable, but lookup functions take const references.
2016-05-25Do not use mempool for GETDATA for tx accepted after the last mempool req.Gregory Maxwell
The ability to GETDATA a transaction which has not (yet) been relayed is a privacy loss vector. The use of the mempool for this was added as part of the mempool p2p message and is only needed to fetch transactions returned by it.
