2014-09-23Do not keep fully spent but unwritten CCoins entries cached.Pieter Wuille
Instead of storing CCoins entries directly in CCoinsMap, store a CCoinsCacheEntry which additionally keeps track of whether a particular entry is: * dirty: potentially different from its parent view. * fresh: the parent view is known to not have a non-pruned version. This allows us to skip non-dirty cache entries when pushing batches of changes up, and to remove CCoins entries about transactions that are fully spent before the parent cache learns about them.
2014-09-23Get rid of CCoinsView's SetCoins and SetBestBlock.Pieter Wuille
All direct modifications are now done through ModifyCoins, and BatchWrite is used for pushing batches of queued modifications up, so we don't need the low-level SetCoins and SetBestBlock anymore in the top-level CCoinsView class.
2014-09-23Use ModifyCoins instead of mutable GetCoins.Pieter Wuille
Replace the mutable non-copying GetCoins method with a ModifyCoins, which returns an encapsulated iterator, so we can keep track of concurrent modifications (as iterators can be invalidated by those) and run cleanup code after a modification is finished. This also removes the overloading of the 'GetCoins' name.
2014-09-03Combine CCoinsViewCache's HaveCoins and const GetCoins into AccessCoins.Pieter Wuille
The efficient version of CCoinsViewCache::GetCoins only works for known-to-exist cache entries, requiring a separate HaveCoins call beforehand. This is inefficient as both perform a hashtable lookup. Replace the non-mutable GetCoins with AccessCoins, which returns a potentially-NULL pointer. This also decreases the overloading of GetCoins. Also replace some copying (inefficient) GetCoins calls with equivalent AccessCoins, decreasing the copying.

Mark the "Get"/"Have" routines in CCoinsView and subclasses as "const".

2014-07-01typedef std::map<uint256, CCoins> to CCoinsMapWladimir J. van der Laan
This makes it possible to switch to a more efficient map type without changing all occurences manually. Merges half of #4413.
2013-11-30Add verbose boolean to getrawmempoolGavin Andresen
Also changes mempool to store CTxMemPoolEntries to keep track of when they enter/exit the pool.
