This change is needed to prevent sync_blocks timeouts in the mempool_reorg test after the sync_blocks update in the upcoming commit "[qa] Change sync_blocks to pick smarter maxheight".

2016-04-27Fix headers announcements edge caseSuhas Daftuar
Previously we would assert that if every block in vBlockHashesToAnnounce is in chainActive, then the blocks to be announced must connect. However, there are edge cases where this assumption could be violated (eg using invalidateblock / reconsiderblock), so just check for this case and revert to inv-announcement instead.

2016-04-27Use txid as key in mapAlreadyAskedForSuhas Daftuar
Previously we used the CInv that would be sent to the peer announcing the transaction as the key, but using the txid instead allows us to decouple the p2p layer from the application logic (which relies on this map to avoid duplicate tx requests).

2016-04-07Track block download times per individual blockPieter Wuille
Currently, we're keeping a timeout for each requested block, starting from when it is requested, with a correction factor for the number of blocks in the queue. That's unnecessarily complicated and inaccurate. As peers process block requests in order, we can make the timeout for each block start counting only when all previous ones have been received, and have a correction based on the number of peers, rather than the total number of blocks.

2016-04-07init: allow shutdown during 'Activating best chain...'Wladimir J. van der Laan
Two-line patch to make it possible to shut down bitcoind cleanly during the initial ActivateBestChain. Fixes #6459 (among other complaints). To reproduce: - shutdown bitcoind - copy chainstate - start bitcoind - let the chain sync a bit - shutdown bitcoind - copy back old chainstate - start bitcoind - bitcoind will catch up with all blocks during Init() (the `boost::this_thread::interruption_point` / `ShutdownRequested()` dance is ugly, this should be refactored all over bitcoind at some point when moving from boost::threads to c++11 threads, but it works...)

2016-02-01Add whitelistforcerelay to control forced relaying. [#7099 redux]Gregory Maxwell
- Add whitelistforcerelay to control forced relaying. Also renames whitelistalwaysrelay. Nodes relay all transactions from whitelisted peers, this gets in the way of some useful reasons for whitelisting peers-- for example, bypassing bandwidth limitations. The purpose of this forced relaying is for specialized gateway applications where a node is being used as a P2P connection filter and multiplexer, but where you don't want it getting in the way of (re-)broadcast. This change makes it configurable with whitelistforcerelay. - Blacklist -whitelistalwaysrelay; replaced by -whitelistrelay.

"permit" is currently used to configure transaction filtering, whereas replacement is more to do with the memory pool state than the transaction itself.

2015-12-21[Mempool] Fix mempool limiting and replace-by-fee for PrioritiseTransactionSuhas Daftuar
1) Fix mempool limiting for PrioritiseTransaction Redo the feerate index to be based on mining score, rather than fee. Update mempool_packages.py to test prioritisetransaction's effect on package scores. 2) Update replace-by-fee logic to use fee deltas 3) Use fee deltas for determining mempool acceptance 4) Remove GetMinRelayFee One test in AcceptToMemoryPool was to compare a transaction's fee agains the value returned by GetMinRelayFee. This value was zero for all small transactions. For larger transactions (between DEFAULT_BLOCK_PRIORITY_SIZE and MAX_STANDARD_TX_SIZE), this function was preventing low fee transactions from ever being accepted. With this function removed, we will now allow transactions in that range with fees (including modifications via PrioritiseTransaction) below the minRelayTxFee, provided that they have sufficient priority.

2015-12-14Replace trickle nodes with per-node/message Poisson delaysPieter Wuille
We used to have a trickle node, a node which was chosen in each iteration of the send loop that was privileged and allowed to send out queued up non-time critical messages. Since the removal of the fixed sleeps in the network code, this resulted in fast and attackable treatment of such broadcasts. This pull request changes the 3 remaining trickle use cases by random delays: * Local address broadcast (while also removing the the wiping of the seen filter) * Address relay * Inv relay (for transactions; blocks are always relayed immediately) The code is based on older commits by Patrick Strateman.
