(Anthony Towns) d07ee77ab Always-active versionbits support (Pieter Wuille) 18e071841 [consensus] Pin P2SH activation to block 173805 on mainnet (John Newbery) 526023aa7 Improve handling of BIP9Deployment limits (Anthony Towns) Pull request description: Most tests shouldn't have to deal with the now-historical SegWit activation transition (and other deployments, but SegWit is certainly the hardest one to accomodate). This PR makes a versionbits starttime of -1 equal to "always active", and enables it by default for SegWit on regtest. Individual tests can override this by using the existing `-vbparams` option. A few unit tests and functional tests are adapted to indeed override vbparams, as they specifically test the transition. This is in preparation for wallet SegWit support, but I thought having earlier eyes on it would be useful.

We came up with a few proposals but settled on the one implemented here as likely the simplest without obvious DoS issues. It uses our existing on-load mapBlockIndex walk to make sure everything that descends from an invalid block is marked as such, and then simply caches blocks which we attempted to connect but which were found to be invalid. To avoid DoS issues during IBD, this will need to depend on #11458. Includes tests from #11487.

2017-10-31Reject headers building on invalid chains by tracking invalidityMatt Corallo
This tracks the set of all known invalid-themselves blocks (ie blocks which we attempted to connect but which were found to be invalid). This is used to cheaply check if new headers build on an invalid chain. While we're at it we also resolve an edge-case in invalidateblock on pruned nodes which results in them needing a reindex if they fail to reorg.
2017-10-31Accept unrequested blocks with work equal to our tipMatt Corallo
This is a simple change that makes our accept requirements the same as our request requirements, (ever so slightly) further decoupling our consensus logic from our FindNextBlocksToDownload logic in net_processing.

2017-10-19Don't process unrequested, low-work blocksSuhas Daftuar
A peer could try to waste our resources by sending us unrequested blocks with low work, eg to fill up our disk. Since e2652002b6011f793185d473f87f1730c625593b we no longer request blocks until we know we're on a chain with more than nMinimumChainWork (our anti-DoS threshold), but we would still process unrequested blocks that had more work than our tip. This commit fixes that behavior.

as 'already there' 258d33b41 [mempool] Mark unaccepted txs present in mempool as 'already there'. (Karl-Johan Alm) Pull request description: I was investigating the reasons for failed imports in mempool and noticed that `LoadMempool()` and `pwallet->postInitProcess()` (for all wallets) are executed concurrently. The wallet will end up importing transactions that `LoadMempool()` later tries to import; the latter will fail due to the tx already being in the mempool. This PR changes the log message, adding an additional "already there" entry. For transactions not accepted into mempool, a check if they are in the mempool is done first, and if found, they are counted as 'already there', otherwise counted as 'failed'. Also slight rewording for consistency (successes, failed, expired, ... -> succeeded, failed, expired).

No changes to behavior.

2017-09-04[mempool] Mark unaccepted txs present in mempool as 'already there'.Karl-Johan Alm
On startup, the wallets will start pumping wallet transactions into the mempool in a different thread while LoadMempool() is running. This will sometimes result in transactions "failing" to be accepted into mempool, but only for the reason that they were already put there by a wallet. The log message for mempool load would note this as a 'failure' to import, which was misleading; it should instead mark it as the transaction already being in the mempool.
