* / / Introduce script verification flagsPieter Wuille2012-11-151-6/+6
|/ / | | | | | | | | | | | | | | These flags select features to be enabled/disabled during script evaluation/checking, instead of several booleans passed along. Currently these flags are defined: * SCRIPT_VERIFY_P2SH: enable BIP16-style subscript evaluation * SCRIPT_VERIFY_STRICTENC: enforce strict adherence to pubkey/sig encoding standards.

| | | | | | | | | | | | | | These command are a leftover from send-to-IP transactions, which have been removed a long time ago. Also removes CNode::mapRequests and CNode::PushRequests, as these were only used for the mentioned commands.

| * | Fixes a race condition in CreateNewBlock and a future null deref on testnet.Gregory Maxwell2012-10-241-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CreateNewBlock was reading pindexBest at the start before taking the lock so it was possible to have the the block content not match the prevheader and this can also trigger a newly added assert in ConnectBlock. I noticed this during a code review after twobitcoins reported that ab91bf39 (BIP30 for all blocks) could cause a null dereference on a modified node that mined during the IBD, or on testnet when it reached heights 91842 and 91880 due to CreateNewBlock calling ConnectBlock with pindex->phashBlock NULL.

* / / Show warning when using prerelease versionWladimir J. van der Laan2012-10-251-0/+4
|/ / | | | | | | | | | | | | | | | | | | | | Implements #1948 - Add macro `CLIENT_VERSION_IS_RELEASE` to clientversion.h - When running a prerelease (the above macro is `false`): - In UI, show an orange warning bar at the top. This will be used for other warnings (and alerts) as well, instead of the status bar. - For `bitcoind`, show the warning in the "errors" field in `getinfo` response.

* | remove init messages from ThreadImport()Philip Kaufmann2012-10-211-3/+0
| | | | | | | | | | | | - remove uiInterface.InitMessage() calls from ThreadImport(), as Qt doesn't like them getting called out of it's main thread and because the thread will continue to run after the GUI was loaded

| | | | | | | | | | This commit adds a status field and a transaction counter to the block indexes.
* | Direct CCoins referencesPieter Wuille2012-10-201-49/+53
| | | | | | | | | | | | | | | | 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.
* | Transaction hash cachingPieter Wuille2012-10-201-20/+20
| | | | | | | | | | | | Use CBlock's vMerkleTree to cache transaction hashes, and pass them along as argument in more function calls. During initial block download, this results in every transaction's hash to be only computed once.
* | Batch block connection during IBDPieter Wuille2012-10-201-87/+59
| | | | | | | | | | | | | | During the initial block download (or -loadblock), delay connection of new blocks a bit, and perform them in a single action. This reduces the load on the database engine, as subsequent blocks often update an earlier block's transaction already.
* | UltraprunePieter Wuille2012-10-201-560/+531
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | Pre-allocate block and undo files in chunksPieter Wuille2012-10-201-9/+32
| | | | | | | | | | | | | | | | | | Introduce a AllocateFileRange() function in util, which wipes or at least allocates a given range of a file. It can be overriden by more efficient OS-dependent versions if necessary. Block and undo files are now allocated in chunks of 16 and 1 MiB, respectively.
* | Multiple blocks per filePieter Wuille2012-10-201-18/+108
| | | | | | | | | | | | | | | | | | | | | | Change the block storage layer again, this time with multiple files per block, but tracked by txindex.dat database entries. The file format is exactly the same as the earlier blk00001.dat, but with smaller files (128 MiB for now). The database entries track how many bytes each block file already uses, how many blocks are in it, which range of heights is present and which range of dates.
* | Preliminary undo file creationPieter Wuille2012-10-201-0/+17
| | | | | | | | | | Create files (one per block) with undo information for the transactions in it.
* | One file per blockPieter Wuille2012-10-201-69/+34
| | | | | | | | | | Refactor of the block storage code, which now stores one file per block. This will allow easier pruning, as blocks can be removed individually.
* | Compact serialization for amountsPieter Wuille2012-10-201-0/+54
| | | | | | | | | | | | | | 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.
