to hide tx time d45b344ffd Bucket for inbound when scheduling invs to hide tx time (Gleb) Pull request description: It has been brought up to my attention that current random delays mechanism (originally intended to obfuscate transaction metadata) allows to easily estimate the time a transaction was received by a node. It may be done by connecting multiple observer nodes to the same node. Each of those nodes will generate its own schedule of delays. Combined metadata regarding those events from different sources allows an observer to estimate transaction time. After this patch a spy won't gain additional information by just creating multiple connections to a target.

25bc9615b7 Document validationinterace callback blocking deadlock potential. (Matt Corallo) Pull request description: From the branches-I've-had-lying-around-and-forgot-to-PR department... This is a comment-only PR, but the comments point out an API quirk that isn't exactly trivial. None of our use-cases right now hit this, but if we were to call SyncWithValidationInterfaceQueue (eg to limit queue depth) in ATMP, I'm pretty sure we'd hit a deadlock there.

2018-05-15net: Serve blocks directly from disk when possibleWladimir J. van der Laan
In `ProcessGetBlockData`, send the block data directly from disk if type MSG_WITNESS_BLOCK is requested. This is a valid shortcut as the on-disk format matches the network format. This is expected to increase performance because a deserialization and subsequent serialization roundtrip is avoided.

b55555d rpc: Add testmempoolaccept (MarcoFalke) Pull request description: To check if a single raw transaction makes it into the current transaction pool, one had to call `sendrawtransaction`. However, on success, this adds the transaction to the mempool with no easy way to undo.

This PR adds a `-blocksdir` option that allows one to keep the blockfiles and the blockindex external from the data directory (instead of creating symlinks). I fist had an option to keep the blockindex within the datadir, but seems to make no sense since accessing the index will (always) lead to access (r/w) the block files.

The main split was a big step, but validation.cpp is still a somewhat ranomly-mixed bag of functions that are pure functions which validate inputs (which should probably either merge with their callers or move into another file in consensus/), read/write data from disk, manipulate our current chain state (which moves into CChainState), and do mempool transaction validation. Obviously this is only a small step, but some effort is made to clean up what functions the functions in CChainState call, and obviously as things are added its easy to keep clear "CChainState::* cannot call anything except via callbacks through CValidationInterface, pure functions, or disk read/write things". Right now there are some glaring violations in mempool callbacks, and general flushing logic needs cleaning up (FlushStateToDisk maybe shouldnt be called, and there should be an API towards setDirtyBlockIndex, but I'll leave that for after @sipa's current changesets land).

- Move comment about transaction/block weight calculation so it applies not only to the GetBlockWeight function but also to GetTransactionWeight - Fix comment in validation.cpp referencing future deployment of BIP113. It has already been deployed. - The doc comment for BLOCK_DOWNLOAD_WINDOW wasn't updated since pruning was introduced, so it still refers to pruning as something that might happen in the future.

Combine fLimitFree and fOverrideMempoolLimit into a single boolean: bypass_limits. This is used to indicate that mempool limiting based on feerate should be bypassed. It is used when readding transactions from a reorg and then the mempool is trimmed to size after all transactions are added and they can be evaluated in the context of their descendants. No changes to behavior.
