6f6514a08090b37b5e8c086015ee4881813ef867 Correct units for "-dbcache" and "-prune" (Hennadii Stepanov) Pull request description: Actually, all `dbcache`-related values in the code are measured in MiB (not in megabytes, MB) or in bytes (e.g., `nTotalCache`). See: https://github.com/bitcoin/bitcoin/blob/master/src/txdb.h https://github.com/bitcoin/bitcoin/blob/ba8c8b22272ad40fe2de465d7e745532bab48d3b/src/init.cpp#L1405-L1424 Also, "-prune" is fixed: 1. The GUI values in GB are translated to the node values in MiB correctly. 2. The maximum of the "prune" `QSpinBox` is not limited by default value of 99 (GB).

bf2e01097 uint256: Remove unnecessary crypto/common.h use (Karl-Johan Alm) Pull request description: This is an alternative to #13242 which keeps the `ReadLE64` part, but moves the `crypto/common.h` dependency into `crypto/common.h` as a function outside of `uint256`. **Reason:** this change will remove dependencies for `uint256` to `crypto/common.h`, `compat/endian.h`, and `compat/byteswap.h`. This PR removes the need to update tests to be endian-aware/-independent, but keeps the (arguably dubious) `ReadLE64` part (which was only introduced to fix the tests, not for any functionality).

2018-10-27Merge #13783: validation: Pass tx pool reference into CheckSequenceLocksMarcoFalke
fa511e8dad Pass tx pool reference into CheckSequenceLocks (MarcoFalke) Pull request description: `CheckSequenceLocks` is called from ATMP and the member function `CTxMemPool::removeForReorg` without passing in the tx pool object that is used in those function's scope and instead using the global `::mempool` instance. This fix should be refactoring only, since currently there is only one (global) tx pool in normal operation. Though, it fixes hard to track down issues in future settings where more than one mempool exists at a time.

Call sync.h primitives "locks" and "mutexes" instead of "blocks" and "waitable critical sections" to match current coding conventions and c++11 standard names. This PR does not rename the "CCriticalSection" class (though this could be done as a followup) because it is used everywhere and would swamp the other changes in this PR.

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.

This is a comment-only PR, but the comments point out an API quirk that isn't exactly trivial.

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.

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).
