| * | | | Reorganize(): remove spurious TxnAbort()Jeff Garzik2012-05-191-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If Reorganize() fails, then its caller, CBlock::SetBestChain(), will call TxnAbort(). Redundant TxnAbort() calls are harmless. The second will return an error return value, with no other side effects. TxnAbort() return values are generally never checked. The impact is nil.

| * | | | | Further DoS prevention: Verify signatures lastGavin Andresen2012-05-181-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Loop over all inputs doing inexpensive validity checks first, and then loop over them a second time doing expensive signature checks. This helps prevent possible CPU exhaustion attacks where an attacker tries to make a victim waste time checking signatures for invalid transactions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove orphan transactions from memory once all of their parent transactions are received and they're still not valid. Thanks to Sergio Demian Lerner for suggesting this fix.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Signals now go directly from the core to WalletModel/ClientModel. - WalletModel subscribes to signals on CWallet: Prepares for multi-wallet support, by no longer assuming an implicit global wallet. - Gets rid of noui.cpp, the few lines that were left are merged into init.cpp - Rename wxXXX message flags to MF_XXX, to make them UI indifferent. - ThreadSafeMessageBox no longer returns the value `4` which was never used, converted to void.
* | | | | | | Fine-grained UI updatesWladimir J. van der Laan2012-05-201-3/+19
| |_|/ / / / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gets rid of `MainFrameRepaint` in favor of specific update functions that tell the UI exactly what changed. This improves the efficiency of various handlers. Also fixes problems with mined transactions not showing up until restart. The following notifications were added: - `NotifyBlocksChanged`: Block chain changed - `NotifyKeyStoreStatusChanged`: Wallet status (encrypted, locked) changed. - `NotifyAddressBookChanged`: Address book entry changed. - `NotifyTransactionChanged`: Wallet transaction added, removed or updated. - `NotifyNumConnectionsChanged`: Number of connections changed. - `NotifyAlertChanged`: New, updated or cancelled alert. As this finally makes it possible for the UI to know when a new alert arrived, it can be shown as OS notification. These notifications could also be useful for RPC clients. However, currently, they are ignored in bitcoind (in noui.cpp). Also brings back polling with timer for numBlocks in ClientModel. This value updates so frequently during initial download that the number of signals clogs the UI thread and causes heavy CPU usage. And after initial block download, the value changes so rarely that a delay of half a second until the UI updates is unnoticable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pull request #948 introduced a fix for nodes stuck on a long side branch of the main chain.

This commits fixes it by sending the request directly.
