| * | | | Create new BlockPolicyEstimator for fee estimatesAlex Morcos2015-05-131-3/+3
| | |_|/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This class groups transactions that have been confirmed in blocks into buckets, based on either their fee or their priority. Then for each bucket, the class calculates what percentage of the transactions were confirmed within various numbers of blocks. It does this by keeping an exponentially decaying moving history for each bucket and confirm block count of the percentage of transactions in that bucket that were confirmed within that number of blocks. -Eliminate txs which didn't have all inputs available at entry from fee/pri calcs -Add dynamic breakpoints and tracking of confirmation delays in mempool transactions -Remove old CMinerPolicyEstimator and CBlockAverage code -New smartfees.py -Pass a flag to the estimation code, using IsInitialBlockDownload as a proxy for when we are still catching up and we shouldn't be counting how many blocks it takes for transactions to be included. -Add a policyestimator unit test

* | | | | | Replace mruset setAddrKnown with CRollingBloomFilter addrKnownGavin Andresen2015-04-301-5/+5
| |/ / / / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use a probabilistic bloom filter to keep track of which addresses we think we have given our peers, instead of a list. This uses much less memory, at the cost of sometimes failing to relay an address to a peer-- worst case if the bloom filter happens to be as full as it gets, 1-in-1,000. Measured memory usage of a full mruset setAddrKnown: 650Kbytes Constant memory usage of CRollingBloomFilter addrKnown: 37Kbytes. This will also help heap fragmentation, because the 37K of storage is allocated when a CNode is created (when a connection to a peer is established) and then there is no per-item-remembered memory allocation. I plan on testing by restarting a full node with an empty peers.dat, running a while with -debug=addrman and -debug=net, and making sure that the 'addr' message traffic out is reasonable. (suggestions for better tests welcome)

| * | | | Change download logic to allow calling getheaders/getdata on inbound peersSuhas Daftuar2015-04-021-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SendMessages will now call getheaders on both inbound and outbound peers, once the headers chain is close to synced. It will also try downloading blocks from inbound peers once we're out of initial block download (so inbound peers will participate in parallel block fetching for the last day or two of blocks being downloaded).
* | | | | Add block pruning functionalitymrbandrews2015-04-221-30/+248
| |/ / / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a -prune=N option to bitcoind, which if set to N>0 will enable block file pruning. When pruning is enabled, block and undo files will be deleted to try to keep total space used by those files to below the prune target (N, in MB) specified by the user, subject to some constraints: - The last 288 blocks on the main chain are always kept (MIN_BLOCKS_TO_KEEP), - N must be at least 550MB (chosen as a value for the target that could reasonably be met, with some assumptions about block sizes, orphan rates, etc; see comment in main.h), - No blocks are pruned until chainActive is at least 100,000 blocks long (on mainnet; defined separately for mainnet, testnet, and regtest in chainparams as nPruneAfterHeight). This unsets NODE_NETWORK if pruning is enabled. Also included is an RPC test for pruning (pruning.py). Thanks to @rdponticelli for earlier work on this feature; this is based in part off that work.

| * Regression test for ResendWalletTransactionsGavin Andresen2015-03-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a regression test for the wallet's ResendWalletTransactions function, which uses a new, hidden RPC command "resendwallettransactions." I refactored main's Broadcast signal so it is passed the best-block time, which let me remove a global variable shared between main.cpp and the wallet (nTimeBestReceived). I also manually tested the "rebroadcast unconfirmed every half hour or so" functionality by: 1. Running bitcoind -connect=0.0.0.0:8333 2. Creating a couple of send-to-self transactions 3. Connect to a peer using -addnode 4. Waited a while, monitoring debug.log, until I see: ```2015-03-23 18:48:10 ResendWalletTransactions: rebroadcast 2 unconfirmed transactions``` One last change: don't bother putting ResendWalletTransactions messages in debug.log unless unconfirmed transactions were actually rebroadcast.

| * fix possible block db breakage during re-indexCory Fields2015-03-101-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When re-indexing, there are a few cases where garbage data may be skipped in the block files. In these cases, the indices are correctly written to the index db, however the pointer to the next position for writing in the current block file is calculated by adding the sizes of the valid blocks found. As a result, when the re-index is finished, the index db is correct for all existing blocks, but the next block will be written to an incorrect offset, likely overwriting existing blocks. Rather than using the sum of all valid blocks to determine the next write position, use the end of the last block written to the file. Don't assume that the current block is the last one in the file, since they may be read out-of-order.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only time when a client sends a "getaddr" message is when he esatblishes an Outbound connection (see ProcessMessage() in src/main.cpp). Another bitcoin client is expected to receive a "getaddr" message only on Inbound connection. Ignoring "gettaddr" requests on Outbound connections can resolve potential privacy issues (and as was said such request normally do not happen anyway).
