2017-05-26Introduce Coin, a single unspent outputPieter Wuille
2017-05-26Store/allow tx metadata in all undo recordsPieter Wuille
Previously, transaction metadata (height, coinbase or not, and before the previous commit also nVersion) was only stored for undo records that correspond to the last output of a transaction being spent. This only saves 2 bytes per undo record. Change this to storing this information for every undo record, and stop complaining for having it in non-last output spends. This means that undo dat written with this patch won't be readable by older versions anymore.
2017-05-26Report on-disk size in gettxoutsetinfoPieter Wuille
2017-05-26Remove/ignore tx version in utxo and undoPieter Wuille
This makes the following changes: * In undo data and the chainstate database, the transaction nVersion field is removed from the data structures, always written as 0, and ignored when reading. * The definition of hash_serialized in gettxoutsetinfo is changed to no longer incude the nVersion field. It is renamed to hash_serialized_2 to avoid confusion. The new definition also includes transaction height and coinbase information, as this information was missing before. This depends on having a CHashVerifier-based undo data checksum verifier. Apart from changing the definition of serialized_hash, downgrading after using this patch is supported, as no release ever used the value of nVersion field in UTXO entries.
2017-05-26Add specialization of SipHash for 256 + 32 bit dataPieter Wuille
We'll need a version of SipHash for tuples of 256 bits and 32 bits data, when CCoinsViewCache switches from using txids to COutPoints as keys.
2017-05-26Introduce CHashVerifier to hash read dataPieter Wuille
This is necessary later, when we drop the nVersion field from the undo data. At that point deserializing and reserializing the data won't roundtrip anymore, and thus that approach can't be used to verify checksums anymore. With this CHashVerifier approach, we can deserialize while hashing the exact serialized form that was used. This is both more efficient and more correct in that case.
2017-05-26error() in disconnect for disk corruption, not inconsistencyPieter Wuille
The error() function unconditionally reports an error. It should only be used for actually exception situations, and not for the type of inconsistencies that ApplyTxInUndo/DisconnectBlock can graciously deal with. This also makes a subtle semantics change: in ApplyTxInUndo, when a record with metadata is encountered (indicating it is the last spend from a tx), don't wipe the CCoins record if it wasn't empty at that point. This makes sure that UTXO operations never affect any other UTXOs (including those from the same tx).
2017-05-26Add SizeEstimate to CDBBatchPieter Wuille
This allows estimating the in-memory size of a LevelDB batch.

2017-05-23Add Qt tests for wallet spends & bumpfeeRussell Yanofsky
A few code changes were needed to accompany the test: * Adding setObjectName() calls for a few Qt controls to make them easily accessible from the test. * Calling contextMenu->popup() instead of contextMenu->exec() to open the transaction list context menu without blocking the test thread. * Opening the context menu at the contextualMenu event point rather than the cursor position (this change was not strictly needed to make the test work, but is more correct). * Updating the bumped transaction row with showTransaction=true instead of false. This is needed to prevent the bumped tx from being hidden, so the last part of the test which attempts to bump the bumped tx can work. (Technically this change is a more general bugfix not limited to the testing environment, but the bug doesn't happen outside of the testing environment because in the full Qt client, a queued NotifyTransactionChanged notification causes the row to be updated twice, first with showTransaction=false, then immediately after with showTransaction=true.)
