* [NOD-420] Delay blocks with valid timestamp (non-delayed) that point to a delayed block. * [NOD-420] Mark block as requested when setting as delayed. * [NOD-420] Merge master; Use dag.timeSource.AdjustedTime() instead of time.Now; * [NOD-420] Return nil when not expecting an error * [NOD-420] Initialise delyaed blocks mapping * [NOD-420] Trigger delayed blocks processing every time we process a block. * [NOD-420] Hold the read lock in processDelayedBlocks * [NOD-420] Add delayed blocks heap sorted by their process time so we could process them in order. * [NOD-420] Update debug log * [NOD-420] Fix process blocks loop * [NOD-420] Add comment * [NOD-420] Log error message * [NOD-420] Implement peek method for delayed block heap. extract delayed block processing to another function. * [NOD-420] Trigger process delayed blocks only in process block * [NOD-420] Move delayed block addition to process block * [NOD-420] Use process block to make sure we fully process the delayed block and deal with orphans. * [NOD-420] Unexport functions when not needed; Return isDelayed boolean from ProcessBlock instead of the delay duration * [NOd-420] Remove redundant delayedBlocksLock * [NOD-420] Resolve merge conflict; Return delay 0 instead of boolean * [NOD-420] Do not treat delayed block as orphan * [NOD-420] Make sure block is not processed if we have already sa delayed. * [NOD-420] Process delayed block if parent is delayed to make sure it would not be treated as orphan. * [NOD-420] Rename variable * [NOD-420] Rename function. Move maxDelayOfParents to process.go * [NOD-420] Fix typo * [NOD-420] Handle errors from processDelayedBlocks properly * [NOD-420] Return default values if err != nil from dag.addDelayedBlock * [NOD-420] Return default values if err != nil from dag.addDelayedBlock in another place Co-authored-by: Svarog <feanorr@gmail.com>
