2013-06-20Refactor keytime/metadata and wallet encryption bugfixPieter Wuille
Refactor keytime: * Key metadata is kept in a CWallet::mapKeyMetadata (std::map<CKeyId,CKeyMetadata>). * When generating a new key, time is put in that map, and new key is written. * AddKeyPubKey and AddCryptedKey do not take a creation time argument, but instead pull it from that map, if it exists there. Bugfix: * AddKeyPubKey and AddCryptedKey in CWallet didn't override the CKeyStore definition anymore. This is fixed, as they no longed need the nCreationTime argument now. Also a few related other changes: * Metadata can be overwritten. * Only GenerateNewKey calls GetTime(), as it's the only place where we know for sure a key was not constructed earlier. * When the nTimeFirstKey is known to be inaccurate, it is set to the value 1 (instead of 0, which would mean unknown). * Use CPubKey instead of std::vector<unsigned char> where possible.

2013-06-10Wallet: optimize rescan to skip blocks prior to birthdayJeff Garzik
2013-06-10Wallet: store key creation time. Calculate whole-wallet birthday.Jeff Garzik
This also encapsulate wallet-read state information into CWalletScanState.
2013-06-05Removed AcceptToMemoryPool method from CTransaction. This method belongs to ↵Eric Lombrozo
the mempool instance. Removed AreInputsStandard from CTransaction, made it a regular function in main. Moved CTransaction::GetOutputFor to CCoinsViewCache. Moved GetLegacySigOpCount and GetP2SHSigOpCount out of CTransaction into regular functions in main. Moved GetValueIn and HaveInputs from CTransaction into CCoinsViewCache. Moved AllowFree, ClientCheckInputs, CheckInputs, UpdateCoins, and CheckTransaction out of CTransaction and into main. Moved IsStandard and IsFinal out of CTransaction and put them in main as IsStandardTx and IsFinalTx. Moved GetValueOut out of CTransaction into main. Moved CTxIn, CTxOut, and CTransaction into core. Added minimum fee parameter to CTxOut::IsDust() temporarily until CTransaction is moved to core.h so that CTxOut needn't know about CTransaction.
2013-06-05Moved CInPoint to core. Removed GetMinFee from CTransaction and made it a ↵Eric Lombrozo
regular function in main.

Use boost::asio::deadline_timer for walletpassphrase timeout

2013-05-12Make FindBlockByHeight constant-time.Pieter Wuille
Remove the pnext pointer in CBlockIndex, and replace it with a vBlockIndexByHeight vector (no effect on memory usage). pnext can now be replaced by vBlockIndexByHeight[nHeight+1], but FindBlockByHeight becomes constant-time. This also means the entire mapBlockIndex structure and the block index entries in it become purely blocktree-related data, and independent from the currently active chain, potentially allowing them to be protected by separate mutexes in the future.
2013-05-07Use boost::asio::deadline_timer for walletpassphrase timeoutGavin Andresen
New method in bitcoinrpc: RunLater, that uses a map of deadline timers to run a function later. Behavior of walletpassphrase is changed; before, calling walletpassphrase again before the lock timeout passed would result in: Error: Wallet is already unlocked. You would have to call lockwallet before walletpassphrase. Now: the last walletpassphrase with correct password wins, and overrides any previous timeout. Fixes issue# 1961 which was caused by spawning too many threads. Test plan: Start with encrypted wallet, password 'foo' NOTE: python -c 'import time; print("%d"%time.time())' ... will tell you current unix timestamp. Try: walletpassphrase foo 600 getinfo EXPECT: unlocked_until is about 10 minutes in the future walletpassphrase foo 1 sleep 2 sendtoaddress mun74Bvba3B1PF2YkrF4NsgcJwHXXh12LF 11 EXPECT: Error: Please enter the wallet passphrase with walletpassphrase first. walletpassphrase foo 600 walletpassphrase foo 0 getinfo EXPECT: wallet is locked (unlocked_until is 0) walletpassphrase foo 10 walletpassphrase foo 600 getinfo EXPECT: wallet is unlocked until 10 minutes in future walletpassphrase foo 60 walletpassphrase bar 600 EXPECT: Error, incorrect passphrase getinfo EXPECT: wallet still scheduled to lock 60 seconds from first (successful) walletpassphrase

2013-05-02Do not write to wallet during LoadWalletGavin Andresen
When debugging another issue, I found a hang-during-startup race condition due to LoadWallet calling SetMinVersion (via LoadCryptedKey). Writing to the file that you're in the process of reading is a bad idea.
2013-04-25Allow the default key to be unavailablePieter Wuille
This solves the issue where no default key can be added after -salvagewallet.

2013-02-18Internal RNG for approximateBestSubset to prevent degenerate behavior.Gregory Maxwell
This fixes test_bitcoin failures on openbsd reported by dhill on IRC. On some systems rand() is a simple LCG over 2^31 and so it produces an even-odd sequence. ApproximateBestSubset was only using the least significant bit and so every run of the iterative solver would be the same for some inputs, resulting in some pretty dumb decisions. Using something other than the least significant bit would paper over the issue but who knows what other way a system's rand() might get us here. Instead we use an internal RNG with a period of something like 2^60 which is well behaved. This also makes it possible to make the selection deterministic for the tests, if we wanted to implement that.
2013-02-05Make transactions larger than 100K non-standardGavin Andresen
Extremely large transactions with lots of inputs can cost the network almost as much to process as they cost the sender in fees. We would never create transactions larger than 100K big; this change makes transactions larger than 100K non-standard, so they are not relayed/mined by default. This is most important for miners that might create blocks larger than 250K big, who could be vulnerable to a make-your-blocks-so-expensive-to-verify-they-get-orphaned attack.
2013-02-04Fix getbalance discrepencyGavin Andresen
Two changes: Use IsConfirmed() instead of IsFinal(), so 'getbalance "*" 0' uses the same 'is this output spendable' criteria as 'getbalance'. Fixes issue #172. And a tiny refactor to CWallet::GetBalance() (redundant call to IsFinal -- IsConfirmed calls IsFinal). getbalance with no arguments and 'getbalance "*" 0' could return different different results,

2013-01-16Replace RelayMessage with RelayTransaction.Matt Corallo
2013-01-15Remove IsFromMe() check in CTxMemPool::accept()Gavin Andresen
Fixes issue #2178 : attacker could penny-flood with invalid-signature transactions to deduce which addresses belonged to your node. I'm committing this early for code review; I still need to write up a test plan. Executive summary of fix: check all transactions received from the network for penny-flood rate-limiting before adding to the memory pool. But do NOT ratelimit transactions added to the memory pool: - because of blockchain reorgs - stored in the wallet and added at startup - sent from the GUI or one of the send* RPC commands (CWallet::CommitTransaction) The limit-free-transactions code really should be a method on CNode, with counters per-peer. But that is a bigger change for another day.
2012-12-26If the prio. will be enough after the next block don't force fees.Gregory Maxwell
If the user was really after the fastest possible confirmation times they would be manually setting a fee. In cases where the wallet builds a transaction with a priority that is too low to qualify as free until the next block, go ahead without a fee. Confirmation frequently takes multiple blocks even when a minimum fee is provided.
2012-12-14In listaddressgroupings push down the IsMine check to run on each input.Gregory Maxwell
This avoids a potential crash when trying to read the scrippubkeys on transactions where the first input IsMine but some of the rest are not when running listaddressgroupings.

2012-11-01Bugfix: do not keep relaying spent wallet transactionsPieter Wuille
The original test (checking whether the transaction occurs in the txindex) is not usable anymore, as it will miss anything already fully spent. However, as merkle transactions (and by extension, wallet transactions) track which block they were last seen being included in, we can use that to determine the need for rebroadcasting.

2012-10-20Transaction hash cachingPieter Wuille
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.
