48 : /* Replay concepts:
49 :
50 : - Blocks are aggregations of entries aka. microblocks which are
51 : groupings of txns and are constructed by the block producer (see
52 : fd_pack).
53 :
54 : - Entries are grouped into entry batches by the block producer (see
55 : fd_pack / fd_shredder).
56 :
57 : - Entry batches are divided into chunks known as shreds by the block
58 : producer (see fd_shredder).
59 :
60 : - Shreds are grouped into forward-error-correction sets (FEC sets) by
61 : the block producer (see fd_shredder).
62 :
63 : - Shreds are transmitted to the rest of the cluster via the Turbine
64 : protocol (see fd_shredder / fd_shred).
65 :
66 : - Once enough shreds within a FEC set are received to recover the
67 : entirety of the shred data encoded by that FEC set, the receiver
68 : can "complete" the FEC set (see fd_fec_resolver).
69 :
70 : - If shreds in the FEC set are missing such that it can't complete,
71 : the receiver can use the Repair protocol to request missing shreds
72 : in FEC set (see fd_repair).
73 :
74 : - The current Repair protocol does not support requesting coding
75 : shreds. As a result, some FEC sets might be actually complete
76 : (contain all data shreds). Repair currently hacks around this by
77 : forcing completion but the long-term solution is to add support for
78 : fec_repairing coding shreds via Repair.
79 :
80 : - FEC sets are delivered in partial-order to the Replay tile by the
81 : Repair tile. Currently Replay only supports replaying entry batches
82 : so FEC sets need to reassembled into an entry batch before they can
83 : be replayed. The new Dispatcher will change this by taking a FEC
84 : set as input instead. */

216 : /* A note on publishing ...
217 :
218 : The watermarks are used to publish our fork-aware structures. For
219 : example, store, banks, and txncache need to be published to release
220 : resources occupied by rooted or dead blocks. In general,
221 : publishing has the effect of pruning forks in those structures,
222 : indicating that it is ok to release the memory being occupied by
223 : the blocks on said forks. Tower is responsible for informing us of
224 : the latest block on the consensus rooted fork. As soon as we can,
225 : we should move the published root as close as possible to the
226 : latest consensus root, publishing/pruning everything on the fork
227 : tree along the way. That is, all the blocks that directly descend
228 : from the current published root (inclusive) to the new published
229 : root (exclusive) on the rooted fork, as well as all the minority
230 : forks that branch from said blocks.
231 :
232 : Ideally, we'd move the published root to the consensus root
233 : immediately upon receiving a new consensus root. However, that's
234 : not always safe to do. One thing we need to be careful about is
235 : making sure that there are no more users/consumers of
236 : soon-to-be-pruned blocks, lest a use-after-free occurs. This can
237 : be done by using a reference counter for each block. Any
238 : concurrent activity, such as transaction execution in the exec
239 : tiles, should retain a refcnt on the block for as
240 : long as it needs access to the shared fork-aware structures related
241 : to that block. Eventually, refcnt on a given block will drop down
242 : to 0 as the block either finishes replaying or gets marked as dead,
243 : and any other tile that has retained a refcnt on the block releases
244 : it. At that point, it becomes a candidate for pruning. The key to
245 : safe publishing then becomes figuring out how far we could advance
246 : the published root, such that every minority fork branching off of
247 : blocks in between the current published root (inclusive) and the
248 : new published root (exclusive) is safe to be pruned. This is a
249 : straightforward tree traversal, where if a block B on the rooted
250 : fork has refcnt 0, and all minority forks branching off of B also
251 : have refcnt 0, then B is safe to be pruned. We advance the
252 : published root to the farthest consecutively prunable block on the
253 : rooted fork. Note that reasm presents the replay tile with a clean
254 : view of the world where every block is chained off of a parent
255 : block. So there are no orpahned/dangling tree nodes to worry
256 : about. The world is a nice single tree as far as replay is
257 : concerned.
258 :
259 : In the following fork tree, every node is a block and the number in
260 : parentheses is the refcnt on the block. The chain marked with
261 : double slashes is the rooted fork. Suppose the published root is
262 : at block P, and consensus root is at block T. We can't publish
263 : past block P because Q has refcnt 1.

280 : blocks we might be actively replaying
281 :
282 :
283 : When refcnt on Q drops to 0, we would be able to advance the
284 : published root to block M, because blocks P, A, and B, as well as
285 : all subtrees branching off of them, have refcnt 0, and therefore
286 : can be pruned. Block M itself cannot be pruned yet because its
287 : child block D has refcnt 2. After publishing/pruning, the fork
288 : tree would be:
289 :

291 : M(0)

299 : blocks we might be actively replaying
300 :
301 :
302 : As a result, the shared fork-aware structures can free resources
303 : for blocks P, A, B, and all subtrees branching off of them.
304 :
305 : For the reference counting part, the replay tile is the sole entity
306 : that can update the refcnt. This ensures that all refcnt increment
307 : and decrement attempts are serialized at the replay tile, and that
308 : there are no racy resurrection of a soon-to-be-pruned block. If a
309 : refcnt increment request arrives after a block has been pruned,
310 : replay simply rejects the request.
311 :
312 : A note on the implementation of the above ...
313 :
314 : Upon receiving a new consensus root, we descend down the rooted
315 : fork from the current published root to the new consensus root. On
316 : each node/block of the rooted fork, we do a summation of the refcnt
317 : on the block and all the minority fork blocks branching from the
318 : block. If the summation is 0, the block is safe for pruning. We
319 : advance the published root to the far end of the consecutive run of
320 : 0 refcnt sums originating from the current published root. On our
321 : descent down the minority forks, we also mark any block that hasn't
322 : finished replaying as dead, so we don't waste time executing them.
323 : No more transactions shall be dispatched for execution from dead
324 : blocks.
325 :
326 : Blocks start out with a refcnt of 0. Other tiles may send a
327 : request to the replay tile for a reference on a block. The
328 : transaction dispatcher is another source of refcnt updates. On
329 : every dispatch of a transaction for block B, we increment the
330 : refcnt for B. And on every transaction finalization, we decrement
331 : the refcnt for B. This means that whenever the refcnt on a block
332 : is 0, there is no more reference on that block from the execution
333 : pipeline. While it might be tempting to simply increment the
334 : refcnt once when we start replaying a block, and decrement the
335 : refcnt once when we finish a block, this more fine-grained refcnt
336 : update strategy allows for aborting and potentially immediate
337 : pruning of blocks under interleaved block replay. Upon receiving a
338 : new consensus root, we can simply look at the refcnt on minority
339 : fork blocks, and a refcnt of 0 would imply that the block is safe
340 : for pruning, even if we haven't finished replaying it. Without the
341 : fine-grained refcnt, we would need to first stop dispatching from
342 : the aborted block, and then wait for a full drain of the execution
343 : pipeline to know for sure that there are no more in-flight
344 : transactions executing on the aborted block. Note that this will
345 : allow the refcnt on any block to transiently drop down to 0. We
346 : will not mistakenly prune an actively replaying block, aka a leaf
347 : node, that is chaining off of the rooted fork, because the
348 : consensus root is always an ancestor of the actively replaying tip.
