43 : /* Replay concepts:
44 :
45 : - Blocks are aggregations of entries aka. microblocks which are
46 : groupings of txns and are constructed by the block producer (see
47 : fd_pack).
48 :
49 : - Entries are grouped into entry batches by the block producer (see
50 : fd_pack / fd_shredder).
51 :
52 : - Entry batches are divided into chunks known as shreds by the block
53 : producer (see fd_shredder).
54 :
55 : - Shreds are grouped into forward-error-correction sets (FEC sets) by
56 : the block producer (see fd_shredder).
57 :
58 : - Shreds are transmitted to the rest of the cluster via the Turbine
59 : protocol (see fd_shredder / fd_shred).
60 :
61 : - Once enough shreds within a FEC set are received to recover the
62 : entirety of the shred data encoded by that FEC set, the receiver
63 : can "complete" the FEC set (see fd_fec_resolver).
64 :
65 : - If shreds in the FEC set are missing such that it can't complete,
66 : the receiver can use the Repair protocol to request missing shreds
67 : in FEC set (see fd_repair).
68 :
69 : - The current Repair protocol does not support requesting coding
70 : shreds. As a result, some FEC sets might be actually complete
71 : (contain all data shreds). Repair currently hacks around this by
72 : forcing completion but the long-term solution is to add support for
73 : fec_repairing coding shreds via Repair.
74 :
75 : - FEC sets are delivered in partial-order to the Replay tile by the
76 : Repair tile. Currently Replay only supports replaying entry batches
77 : so FEC sets need to reassembled into an entry batch before they can
78 : be replayed. The new Dispatcher will change this by taking a FEC
79 : set as input instead. */

187 :
188 : The watermarks are used to publish our fork-aware structures. For
189 : example, store, banks, and txncache need to be published to release
190 : resources occupied by rooted or dead blocks. In general,
191 : publishing has the effect of pruning forks in those structures,
192 : indicating that it is ok to release the memory being occupied by
193 : the blocks on said forks. Tower is responsible for informing us of
194 : the latest block on the consensus rooted fork. As soon as we can,
195 : we should move the published root as close as possible to the
196 : latest consensus root, publishing/pruning everything on the fork
197 : tree along the way. That is, all the blocks that directly descend
198 : from the current published root (inclusive) to the new published
199 : root (exclusive) on the rooted fork, as well as all the minority
200 : forks that branch from said blocks.
201 :
202 : Ideally, we'd move the published root to the consensus root
203 : immediately upon receiving a new consensus root. However, that's
204 : not always safe to do. One thing we need to be careful about is
205 : making sure that there are no more users/consumers of
206 : soon-to-be-pruned blocks, lest a use-after-free occurs. This can
207 : be done by using a reference counter for each block. Any
208 : concurrent activity, such as transaction execution in the exec
209 : tiles, should retain a refcnt on the block for as
210 : long as it needs access to the shared fork-aware structures related
211 : to that block. Eventually, refcnt on a given block will drop down
212 : to 0 as the block either finishes replaying or gets marked as dead,
213 : and any other tile that has retained a refcnt on the block releases
214 : it. At that point, it becomes a candidate for pruning. The key to
215 : safe publishing then becomes figuring out how far we could advance
216 : the published root, such that every minority fork branching off of
217 : blocks in between the current published root (inclusive) and the
218 : new published root (exclusive) is safe to be pruned. This is a
219 : straightforward tree traversal, where if a block B on the rooted
220 : fork has refcnt 0, and all minority forks branching off of B also
221 : have refcnt 0, then B is safe to be pruned. We advance the
222 : published root to the farthest consecutively prunable block on the
223 : rooted fork. Note that reasm presents the replay tile with a clean
224 : view of the world where every block is chained off of a parent
225 : block. So there are no orpahned/dangling tree nodes to worry
226 : about. The world is a nice single tree as far as replay is
227 : concerned.
228 :
229 : In the following fork tree, every node is a block and the number in
230 : parentheses is the refcnt on the block. The chain marked with
231 : double slashes is the rooted fork. Suppose the published root is
232 : at block P, and consensus root is at block T. We can't publish
233 : past block P because Q has refcnt 1.

250 : blocks we might be actively replaying
251 :
252 :
253 : When refcnt on Q drops to 0, we would be able to advance the
254 : published root to block M, because blocks P, A, and B, as well as
255 : all subtrees branching off of them, have refcnt 0, and therefore
256 : can be pruned. Block M itself cannot be pruned yet because its
257 : child block D has refcnt 2. After publishing/pruning, the fork
258 : tree would be:
259 :
260 :
261 : M(0)

268 : ||
269 : blocks we might be actively replaying
270 :
271 :
272 : As a result, the shared fork-aware structures can free resources
273 : for blocks P, A, B, and all subtrees branching off of them.
274 :
275 : For the reference counting part, the replay tile is the sole entity
276 : that can update the refcnt. This ensures that all refcnt increment
277 : and decrement attempts are serialized at the replay tile, and that
278 : there are no racy resurrection of a soon-to-be-pruned block. If a
279 : refcnt increment request arrives after a block has been pruned,
280 : replay simply rejects the request.
281 :
282 : A note on the implementation of the above ...
283 :
284 : Upon receiving a new consensus root, we descend down the rooted
285 : fork from the current published root to the new consensus root. On
286 : each node/block of the rooted fork, we do a summation of the refcnt
287 : on the block and all the minority fork blocks branching from the
288 : block. If the summation is 0, the block is safe for pruning. We
289 : advance the published root to the far end of the consecutive run of
290 : 0 refcnt sums originating from the current published root. On our
291 : descent down the minority forks, we also mark any block that hasn't
292 : finished replaying as dead, so we don't waste time executing them.
293 : No more transactions shall be dispatched for execution from dead
294 : blocks.
295 :
296 : Blocks start out with a refcnt of 0. Other tiles may send a
297 : request to the replay tile for a reference on a block. The
298 : transaction dispatcher is another source of refcnt updates. On
299 : every dispatch of a transaction for block B, we increment the
300 : refcnt for B. And on every transaction finalization, we decrement
301 : the refcnt for B. This means that whenever the refcnt on a block
302 : is 0, there is no more reference on that block from the execution
303 : pipeline. While it might be tempting to simply increment the
304 : refcnt once when we start replaying a block, and decrement the
305 : refcnt once when we finish a block, this more fine-grained refcnt
306 : update strategy allows for aborting and potentially immediate
307 : pruning of blocks under interleaved block replay. Upon receiving a
308 : new consensus root, we can simply look at the refcnt on minority
309 : fork blocks, and a refcnt of 0 would imply that the block is safe
310 : for pruning, even if we haven't finished replaying it. Without the
311 : fine-grained refcnt, we would need to first stop dispatching from
312 : the aborted block, and then wait for a full drain of the execution
313 : pipeline to know for sure that there are no more in-flight
314 : transactions executing on the aborted block. Note that this will
315 : allow the refcnt on any block to transiently drop down to 0. We
316 : will not mistakenly prune an actively replaying block, aka a leaf
317 : node, that is chaining off of the rooted fork, because the
318 : consensus root is always an ancestor of the actively replaying tip.
