2015-11-19Change GetPriority calculation.Alex Morcos
Compute the value of inputs that already are in the chain at time of mempool entry and only increase priority due to aging for those inputs. This effectively changes the CTxMemPoolEntry's GetPriority calculation from an upper bound to a lower bound.

e482a7f Fix CCoins serialization documentation (Peter Josling)
2015-11-04Fix CCoins serialization documentationPeter Josling
The docs talk about bits 2 and 4 instead of 2 and 3, and bits are being indexed from both 1 (describing nCode) and 0 (in second example). Changed to use zero-indexing for all.
2015-11-02ModifyNewCoins saves database lookupsAlex Morcos
When processing a new transaction, in addition to spending the Coins of its txin's it creates a new Coins for its outputs. The existing ModifyCoins function will first make sure this Coins does not already exist. It can not exist due to BIP 30, but because of that the lookup can't be cached and always has to go to the database. Since we are creating the coins to match the new tx anyway, there is no point in checking if they exist first anyway. However this should not be used for coinbase tx's in order to preserve the historical behavior of overwriting the two existing duplicate tx pairs.

2015-01-05Replace direct use of 0 with SetNull and IsNullWladimir J. van der Laan
Replace x=0 with .SetNull(), x==0 with IsNull(), x!=0 with !IsNull(). Replace uses of uint256(0) with uint256().

2014-12-31Make CCoinsViewCache's copy constructor privateLuke Dashjr
It is easily confused with CCoinsViewCache(CCoinsView*), which creates a sub-cache, but instead of creating a sub-cache, the copy constructor would copy the original and use that original's base, defeating the intended isolation.

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.

- ensures a consistent usage in header files - also add a blank line after the copyright header where missing - also remove orphan new-lines at the end of some files

2014-08-07CCoinsKeyHasher::operator() should return size_tWladimir J. van der Laan
It currently returns uint64_t, which on older boost (at least 1.46) causes test failures on 32-bit systems. This problem was introduced in bc42503. Fixes #4634.

This makes it possible to switch to a more efficient map type without changing all occurences manually. Merges half of #4413.
