| | | | | | | | | | - Wiki says "block chain" is correct ;) - remove some unneeded spaces I found in the source, while fixing the spelling

| | | | | | | | | | | | - 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

| | | | | | | | | | | | | | | | Split off CBlockTreeDB and CCoinsViewDB into txdb-*.{cpp,h} files, implemented by either LevelDB or BDB. Based on code from earlier commits by Mike Hearn in his leveldb branch.

* | Prepare database format for multi-stage block processingPieter Wuille2012-10-201-25/+89
| | | | | | | | | | 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.

|/ | | | | | | | | Matt pointed out some time ago that there existed a minor DOS attack where a node in its initial block download could be wedged by an overwrite attack in a fork created between checkpoints before a time where BIP30 was enforced. Now that the BIP30 timestamp is irreversibly past the check can be more aggressive and apply to all blocks except the two historic violations.

| | | | | | | | | | Hard-code a special nId=max int alert, to be broadcast if the alert key is ever compromised. It applies to all versions, never expires, cancels all previous alerts, and has a fixed message: URGENT: Alert key compromised, upgrade required Variations are not allowed (ignored), so an attacker with the private key cannot broadcast empty-message nId=max alerts.
* Alert system DoS preventionGavin Andresen2012-08-261-6/+19
| | | | | | | | | | | This fixes two alert system vulnerabilities found by Sergio Lerner; you could send peers unlimited numbers of invalid alert message to try to either fill up their debug.log with messages and/or keep their CPU busy checking signatures. Fixed by disconnecting/banning peers if they send 10 or more bad (invalid/expired/cancelled) alerts.

* Reject block.nVersion<=1 blocks if network has upgraded to version=2Gavin Andresen2012-08-201-1/+10
| | | | | | | | | | | If 950 of the last 1,000 blocks are nVersion=2, reject nVersion=1 (or zero, but no bitcoin release has created block.nVersion=0) blocks -- 75 of last 100 on testnet3. This rule is being put in place now so that we don't have to go through another "express support" process to get what we really want, which is for every single new block to include the block height in the coinbase.
* Block height in coinbase as a new block ruleGavin Andresen2012-08-201-1/+27
| | | | | | | | | | | "Version 2" blocks are blocks that have nVersion=2 and have the block height as the first item in their coinbase. Block-height-in-the-coinbase is strictly enforced when version=2 blocks are a supermajority in the block chain (750 of the last 1,000 blocks on main net, 51 of 100 for testnet). This does not affect old clients/miners at all, which will continue producing nVersion=1 blocks, and which will continue to be valid.
