2016-12-01Remove orphan state wipe from UnloadBlockIndex.Matt Corallo
As orphan state is now "network state", like in d6ea737be19a0001e69e4e854eb1cef21523ea7a, UnloadBlockIndex is only used during init if we end up reindexing to clear our block state so that we can start over. However, at that time no connections have been brought up as CConnman hasn't been started yet, so all of the network processing state logic is empty when its called.

2016-11-25net: push only raw data into CConnmanCory Fields
This fixes one of the last major layer violations in the networking stack. The network side is no longer in charge of message serialization, so it is now decoupled from Bitcoin structures. Only the header is serialized and attached to the payload.

2016-11-23net: don't send any messages before handshake or after requested disconnectCory Fields
Also, send reject messages earlier in SendMessages(), so that disconnections are processed earlier. These changes combined should ensure that no message is ever sent after fDisconnect is set.
2016-11-23net: Set feelers to disconnect at the end of the version messageCory Fields
This way we're not relying on messages going out after fDisconnect has been set. This should not cause any real behavioral changes, though feelers should arguably disconnect earlier in the process. That can be addressed in a later functional change.

2016-11-22Always drop the least preferred HB peer when adding a new one.Gregory Maxwell
When a BIP152 HB-mode peer is in the least preferred position and disconnects, they will not be by ForNode on the next loop. They will continue to sit in that position and prevent deactivating HB mode for peers that are still connected. There is no reason for them to stay in the list if already gone, so drop the first element unconditionally if there are too many. Fixes issue #9163.

In 0.13 orphan transactions began being treated as implicit INVs for their parents. But the resulting getdata were not getting the witness flag. This fixes issue #9182 reported by chjj and roasbeef on IRC.
2016-11-17Erase orphans per-transaction instead of per-blockMatt Corallo
2016-11-17Move orphan processing to ActivateBestChainMatt Corallo
This further decouples "main" and "net" processing logic by moving orphan processing out of the chain-connecting cs_main lock and into its own cs_main lock, beside all of the other chain callbacks. Once further decoupling of net and main processing logic occurs, orphan handing should move to its own lock, out of cs_main. Note that this will introduce a race if there are any cases where we assume the orphan map to be consistent with the current chain tip, however I am confident there is no such case (ATMP will fail without DoS score in all such cases).

2016-11-07Make GetSerializeSize a wrapper on top of CSizeComputerPieter Wuille
Given that in default GetSerializeSize implementations created by ADD_SERIALIZE_METHODS we're already using CSizeComputer(), get rid of the specialized GetSerializeSize methods everywhere, and just use CSizeComputer. This removes a lot of code which isn't actually used anywhere. For CCompactSize and CVarInt this actually removes a more efficient size computing algorithm, which is brought back in a later commit.
2016-11-07Modify getblocktxn handler not to drop requests for old blocksRussell Yanofsky
The current getblocktxn implementation drops and ignores requests for old blocks, which causes occasional sync_block timeouts during the p2p-compactblocks.py test as reported in https://github.com/bitcoin/bitcoin/issues/8842. The p2p-compactblocks.py test setup creates many new blocks in a short period of time, which can lead to getblocktxn requests for blocks below the hardcoded depth limit of 10 blocks. This commit changes the getblocktxn handler not to ignore these requests, so the peer nodes in the test setup will reliably be able to sync. The protocol change is documented in BIP-152 update "Allow block responses to getblocktxn requests" at https://github.com/bitcoin/bips/pull/469. The protocol change is not expected to affect nodes running outside the test environment, because there shouldn't normally be lots of new blocks being rapidly added that need to be synced.
