02a6702 Add option `-alerts` to opt out of alert system (Wladimir J. van der Laan)
2015-06-15Add option `-alerts` to opt out of alert systemWladimir J. van der Laan
Make it possible to opt-out of the centralized alert system by providing an option `-noalerts` or `-alerts=0`. The default remains unchanged. This is a gentler form of #6260, in which I went a bit overboard by removing the alert system completely. I intend to add this to the GUI options in another pull after this.

2015-06-08Use best header chain timestamps to detect partitioningGavin Andresen
The partition checking code was using chainActive timestamps to detect partitioning; with headers-first syncing, it should use (and with this pull request, does use) pIndexBestHeader timestamps. Fixes issue #6251

da29ecb Consensus: MOVEONLY: Move CValidationState from main consensus/validation (jtimon) 27afcd8 Consensus: Refactor: Decouple CValidationState from main::AbortNode() (Cory Fields)
2015-05-27Fix off-by-one error w/ nLockTime in the walletPeter Todd
Previously due to an off-by-one error the wallet ignored nLockTime-by-height transactions that would be valid in the next block even though they are accepted into the mempool. The transactions wouldn't show up until confirmed, nor would they be included in the unconfirmed balance. Similar to the mempool behavior fix in 665bdd3b, the wallet code was calling IsFinalTx() directly without taking into account the fact that doing so tells you if the transaction could have been mined in the *current* block, rather than the next block. To fix this we strip IsFinalTx() of non-consensus-critical functionality, removing the default arguments, and add CheckFinalTx() to check if a transaction will be final in the next block.

2015-05-14Alert if it is very likely we are getting a bad chainGavin Andresen
Create a monitoring task that counts how many blocks have been found in the last four hours. If very few or too many have been found, an alert is triggered. "Very few" and "too many" are set based on a false positive rate of once every fifty years of constant running with constant hashing power, which works out to getting 5 or fewer or 48 or more blocks in four hours (instead of the average of 24). Only one alert per day is triggered, so if you get disconnected from the network (or are being Sybil'ed) -alertnotify will be triggered after 3.5 hours but you won't get another -alertnotify for 24 hours. Tested with a new unit test and by running on the main network with -debug=partitioncheck Run test/test_bitcoin --log_level=message to see the alert messages: WARNING: check your network connection, 3 blocks received in the last 4 hours (24 expected) WARNING: abnormally high number of blocks generated, 60 blocks received in the last 4 hours (24 expected) The -debug=partitioncheck debug.log messages look like: ThreadPartitionCheck : Found 22 blocks in the last 4 hours ThreadPartitionCheck : likelihood: 0.0777702

This pertains to app-state, so it doesn't make sense to handle inside the checkpoint functions.

691161d Consensus: Create consensus/consensus.h with some constants (jtimon)
2015-04-22Add block pruning functionalitymrbandrews
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.

2015-03-24Regression test for ResendWalletTransactionsGavin Andresen
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.
