* | Direct CCoins referencesPieter Wuille2012-10-201-3/+0
| | | | | | | | | | | | | | | | To prevent excessive copying of CCoins in and out of the CCoinsView implementations, introduce a GetCoins() function in CCoinsViewCache with returns a direct reference. The block validation and connection logic is updated to require caching CCoinsViews, and exploits the GetCoins() function heavily.
* | UltraprunePieter Wuille2012-10-203-29/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This switches bitcoin's transaction/block verification logic to use a "coin database", which contains all unredeemed transaction output scripts, amounts and heights. The name ultraprune comes from the fact that instead of a full transaction index, we only (need to) keep an index with unspent outputs. For now, the blocks themselves are kept as usual, although they are only necessary for serving, rescanning and reorganizing. The basic datastructures are CCoins (representing the coins of a single transaction), and CCoinsView (representing a state of the coins database). There are several implementations for CCoinsView. A dummy, one backed by the coins database (coins.dat), one backed by the memory pool, and one that adds a cache on top of it. FetchInputs, ConnectInputs, ConnectBlock, DisconnectBlock, ... now operate on a generic CCoinsView. The block switching logic now builds a single cached CCoinsView with changes to be committed to the database before any changes are made. This means no uncommitted changes are ever read from the database, and should ease the transition to another database layer which does not support transactions (but does support atomic writes), like LevelDB. For the getrawtransaction() RPC call, access to a txid-to-disk index would be preferable. As this index is not necessary or even useful for any other part of the implementation, it is not provided. Instead, getrawtransaction() uses the coin database to find the block height, and then scans that block to find the requested transaction. This is slow, but should suffice for debug purposes.
* | Compact serialization for amountsPieter Wuille2012-10-201-0/+62
| | | | | | | | | | | | | | Special serializer/deserializer for amount values. It is optimized for values which have few non-zero digits in decimal representation. Most amounts currently in the txout set take only 1 or 2 bytes to represent.
* | Compact serialization for variable-length integersPieter Wuille2012-10-201-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Variable-length integers: bytes are a MSB base-128 encoding of the number. The high bit in each byte signifies whether another digit follows. To make the encoding is one-to-one, one is subtracted from all but the last digit. Thus, the byte sequence a[] with length len, where all but the last byte has bit 128 set, encodes the number: (a[len-1] & 0x7F) + sum(i=1..len-1, 128^i*((a[len-i-1] & 0x7F)+1)) Properties: * Very small (0-127: 1 byte, 128-16511: 2 bytes, 16512-2113663: 3 bytes) * Every integer has exactly one encoding * Encoding does not depend on size of original integer type

| * Handle locked pages more robustly (Fixes issue #1462)Wladimir J. van der Laan2012-08-231-0/+115
| | | | | | | | | | | | | | Memory locks do not stack, that is, pages which have been locked several times by calls to mlock() will be unlocked by a single call to munlock(). This can result in keying material ending up in swap when those functions are used naively. In this commit a class "LockedPageManager" is added that simulates stacking memory locks by keeping a counter per page.
* | Store a fixed order of transactions (and accounting) in the walletLuke Dashjr2012-08-231-0/+123
|/ | | | | For backward compatibility, new accounting data is stored after a \0 in the comment string. This way, old versions and third-party software should load and store them, but all actual use (listtransactions, for example) ignores it.

| * | Refactor: split CKeyID/CScriptID/CTxDestination from CBitcoinAddressPieter Wuille2012-05-247-52/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces internal types: * CKeyID: reference (hash160) of a key * CScriptID: reference (hash160) of a script * CTxDestination: a boost::variant of the former two CBitcoinAddress is retrofitted to be a Base58 encoding of a CTxDestination. This allows all internal code to only use the internal types, and only have RPC and GUI depend on the base58 code. Furthermore, the header dependencies are a lot saner now. base58.h is at the top (right below rpc and gui) instead of at the bottom. For the rest: wallet -> script -> keystore -> key. Only keystore still requires a forward declaration of CScript. Solving that would require splitting script into two layers.
