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. */

211 : /* A note on publishing ...
212 :
213 : The watermarks are used to publish our fork-aware structures. For
214 : example, store, banks, and txncache need to be published to release
215 : resources occupied by rooted or dead blocks. In general,
216 : publishing has the effect of pruning forks in those structures,
217 : indicating that it is ok to release the memory being occupied by
218 : the blocks on said forks. Tower is responsible for informing us of
219 : the latest block on the consensus rooted fork. As soon as we can,
220 : we should move the published root as close as possible to the
221 : latest consensus root, publishing/pruning everything on the fork
222 : tree along the way. That is, all the blocks that directly descend
223 : from the current published root (inclusive) to the new published
224 : root (exclusive) on the rooted fork, as well as all the minority
225 : forks that branch from said blocks.
226 :
227 : Ideally, we'd move the published root to the consensus root
228 : immediately upon receiving a new consensus root. However, that's
229 : not always safe to do. One thing we need to be careful about is
230 : making sure that there are no more users/consumers of
231 : soon-to-be-pruned blocks, lest a use-after-free occurs. This can
232 : be done by using a reference counter for each block. Any
233 : concurrent activity, such as transaction execution in the exec
234 : tiles, should retain a refcnt on the block for as
235 : long as it needs access to the shared fork-aware structures related
236 : to that block. Eventually, refcnt on a given block will drop down
237 : to 0 as the block either finishes replaying or gets marked as dead,
238 : and any other tile that has retained a refcnt on the block releases
239 : it. At that point, it becomes a candidate for pruning. The key to
240 : safe publishing then becomes figuring out how far we could advance
241 : the published root, such that every minority fork branching off of
242 : blocks in between the current published root (inclusive) and the
243 : new published root (exclusive) is safe to be pruned. This is a
244 : straightforward tree traversal, where if a block B on the rooted
245 : fork has refcnt 0, and all minority forks branching off of B also
246 : have refcnt 0, then B is safe to be pruned. We advance the
247 : published root to the farthest consecutively prunable block on the
248 : rooted fork. Note that reasm presents the replay tile with a clean
249 : view of the world where every block is chained off of a parent
250 : block. So there are no orpahned/dangling tree nodes to worry
251 : about. The world is a nice single tree as far as replay is
252 : concerned.
253 :
254 : In the following fork tree, every node is a block and the number in
255 : parentheses is the refcnt on the block. The chain marked with
256 : double slashes is the rooted fork. Suppose the published root is
257 : at block P, and consensus root is at block T. We can't publish
258 : past block P because Q has refcnt 1.

275 : blocks we might be actively replaying
276 :
277 :
278 : When refcnt on Q drops to 0, we would be able to advance the
279 : published root to block M, because blocks P, A, and B, as well as
280 : all subtrees branching off of them, have refcnt 0, and therefore
281 : can be pruned. Block M itself cannot be pruned yet because its
282 : child block D has refcnt 2. After publishing/pruning, the fork
283 : tree would be:

293 : ||
294 : blocks we might be actively replaying
295 :
296 :
297 : As a result, the shared fork-aware structures can free resources
298 : for blocks P, A, B, and all subtrees branching off of them.
299 :
300 : For the reference counting part, the replay tile is the sole entity
301 : that can update the refcnt. This ensures that all refcnt increment
302 : and decrement attempts are serialized at the replay tile, and that
303 : there are no racy resurrection of a soon-to-be-pruned block. If a
304 : refcnt increment request arrives after a block has been pruned,
305 : replay simply rejects the request.
306 :
307 : A note on the implementation of the above ...
308 :
309 : Upon receiving a new consensus root, we descend down the rooted
310 : fork from the current published root to the new consensus root. On
311 : each node/block of the rooted fork, we do a summation of the refcnt
312 : on the block and all the minority fork blocks branching from the
313 : block. If the summation is 0, the block is safe for pruning. We
314 : advance the published root to the far end of the consecutive run of
315 : 0 refcnt sums originating from the current published root. On our
316 : descent down the minority forks, we also mark any block that hasn't
317 : finished replaying as dead, so we don't waste time executing them.
318 : No more transactions shall be dispatched for execution from dead
319 : blocks.
320 :
321 : Blocks start out with a refcnt of 0. Other tiles may send a
322 : request to the replay tile for a reference on a block. The
323 : transaction dispatcher is another source of refcnt updates. On
324 : every dispatch of a transaction for block B, we increment the
325 : refcnt for B. And on every transaction finalization, we decrement
326 : the refcnt for B. This means that whenever the refcnt on a block
327 : is 0, there is no more reference on that block from the execution
328 : pipeline. While it might be tempting to simply increment the
329 : refcnt once when we start replaying a block, and decrement the
330 : refcnt once when we finish a block, this more fine-grained refcnt
331 : update strategy allows for aborting and potentially immediate
332 : pruning of blocks under interleaved block replay. Upon receiving a
333 : new consensus root, we can simply look at the refcnt on minority
334 : fork blocks, and a refcnt of 0 would imply that the block is safe
335 : for pruning, even if we haven't finished replaying it. Without the
336 : fine-grained refcnt, we would need to first stop dispatching from
337 : the aborted block, and then wait for a full drain of the execution
338 : pipeline to know for sure that there are no more in-flight
339 : transactions executing on the aborted block. Note that this will
340 : allow the refcnt on any block to transiently drop down to 0. We
341 : will not mistakenly prune an actively replaying block, aka a leaf
342 : node, that is chaining off of the rooted fork, because the
343 : consensus root is always an ancestor of the actively replaying tip.
