* | update CClientUIInterface and remove orphan Wx stuffPhilip Kaufmann2012-11-261-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - fix ThreadSafeMessageBox always displays error icon - allow to specify MSG_ERROR / MSG_WARNING or MSG_INFORMATION without a custom caption / title - allow to specify CClientUIInterface::ICON_ERROR / ICON_WARNING and ICON_INFORMATION (which is default) as message box icon - remove CClientUIInterface::OK from ThreadSafeMessageBox-calls, as the OK button will be set as default, if none is specified - prepend "Bitcoin - " to used captions - rename BitcoinGUI::error() -> BitcoinGUI::message() and add function documentation - change all style parameters and enum flags to unsigned - update code to use that new API - update Client- and WalletModel to use new BitcoinGUI::message() and rename the classes error() method into message() - include the possibility to supply the wanted icon for messages from Client- and WalletModel via "style" parameter
* | make enum and parameter used in Bind() unsignedPhilip Kaufmann2012-11-141-4/+4
| | | | | | | | | | - it's good practise to use unsigned int for enum flags, so change this one, as I introduced this for Bind()
* | allow listening on -bind=address for blocked networksPhilip Kaufmann2012-11-101-16/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - this allows the client to listen on via -bind specified addresses (e.g. 127.0.0.1), even when a network (IPv4 in that case) was blocked via e.g -onlynet="Tor" - introduce enum BindFlags to avoid passing multiple bools to Bind() - make -bind help text clear we ALWAYS listen on the specified address - remove an unused variable - remove 2 unneeded IsLimited() checks before calling Bind(), which does these checks anyway - usage case: specify -bind=127.0.0.1 -onlynet="Tor" to allow incoming connections to a Tor hidden service, but still don't allow other IPv4 nodes to connect / get connected

| | | | | | | | | | | | As the coinset data refers to the best block, stored in the block tree. Flushing the coin set first can cause inconsistencies if the process gets killed in between.

| | | | | | | | | | | | | | | | 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 Wuille2012-10-201-32/+3
| | | | | | | | | | This commit adds a status field and a transaction counter to the block indexes.
* | Automatically reorganize at startup to best known blockPieter Wuille2012-10-201-0/+34
| | | | | | | | | | | | | | | | | | | | | | Given that the block tree database (chain.dat) and the active chain database (coins.dat) are entirely separate now, it becomes legal to swap one with another instance without affecting the other. This commit introduces a check in the startup code that detects the presence of a better chain in chain.dat that has not been activated yet, and does so efficiently (in batch, while reusing the blk???.dat files).
* | Batch block connection during IBDPieter Wuille2012-10-201-0/+12
| | | | | | | | | | | | | | 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 Wuille2012-10-201-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This commit does three things: 1) Runs a BDB verify early in the startup process, and if there is a low-level problem with the database: + Moves the bad wallet.dat to wallet.timestamp.bak + Runs a 'salvage' operation to get key/value pairs, and writes them to a new wallet.dat + Continues with startup. 2) Much more tolerant of serialization errors. All errors in deserialization are reported by tolerated EXCEPT for errors related to reading keypairs or master key records-- those are reported and then shut down, so the user can get help (or recover from a backup). 3) Adds a new -salvagewallet option, which: + Moves the wallet.dat to wallet.timestamp.bak + extracts ONLY keypairs and master keys into a new wallet.dat + soft-sets -rescan, to recreate transaction history This was tested by randomly corrupting testnet wallets using a little python script I wrote (https://gist.github.com/3812689)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before, opening a -datadir that was created with a new version of Berkeley DB would result in an un-caught DB_RUNRECOVERY exception.
