fix(dot/state): fix deadlock, fixes bootstrap syncing #1959

noot · 2021-11-02T12:52:22Z

Changes

deadlock was caused as GetBlockByHash() calls RLock(), GetBlockByHash() calls GetBlockBody() which previously also called RLock(). this was ok when there were no calls to the write lock Lock() simultaneously. however the deadlock scenario occured when one goroutine was calling GetBlockBody() (with 1 read-lock obtained) and another called SetFinalisedHash() (thus obtaining the write-lock). as a read-lock can no longer be obtained if 1. write-lock was obtained (even if it was freed) and 2. another read-lock was already obtained, this caused a deadlock
I ended up just removing the lock in GetBlockBody() to prevent multiple read-locks from being obtained. if anyone has a better method let me know :D

Tests

make gossamer
./bin/gossamer --chain polkadot

node can sync (up until it hits max memory :p) no more stalling/deadlocks

Why moving CompareAndSetBlockData? There must be a reason but it's not totally mentioned in the description 🤔

yes, sorry I should have mentioned. this should definitely be happening after the block checks happen, otherwise we might be storing some data in the database and the block turns out to be invalid, and then the extra block data is still stored.

-	defer bs.RUnlock()


Are we sure GetBlockBody is not used anywhere else? As in, maybe we need to add locking on other callers using this one?

it isn't used anywhere else in the BlockState, so I think it's probably ok for now. but in the future it might be nice to do some lock overhaul on the BlockState since it could be improved imo.

Maybe unexport that method to make this clearer, if possible?

ah sorry it is used in other spots in the codebase, so gotta leave it like this for now

So are you sure it won't data race on the block state if it's accessed elsewhere in the codebase?

currently, the GetBlockBody just access the unfinalisedBlocks field that is a *sync.Map so by default can prevent concurrent access to the data other than that I'm pretty sure we can remove the locks

yeah there's an edge case potentially with the handleFinalisedBlock function (just pushed a fix for it) previously that function was doing LoadAndDelete on the unfinalized blocks, then storing it in the db. so there was a potential race condition where one process was finalizing a block, and it was deleted from memory but not stored in the db yet, while another process calls GetBlockBody and isn't able to find it in memory or in the db. however my update to handleFinalisedBlock should fix this (it now gets from memory, stores in the db, then deletes from memory)
