SocialConsensus failure at block 414735 feature/sqlite 20.12 #98

Closed tawmaz closed 2 years ago

tawmaz commented 2 years ago

I have reproduced this issue on two systems (Windows + Linux) building from feature/sqlite branch at git commit 78fb244cd0a8775287b9ed7a1c0f535e9d80c67f.

It appears to be a double subscribe issue based on information I have collected from the social consensus validation using gdb: Block: 414735 Block Hash: f9dde29b4b92b0312651b98aa3293c4577c904cfdf217e4fcebfa24b1ab3b189 Result:SocialConsensusResult_DoubleSubscribe (8) TX hash: "a98aa7df032c16c57efe153b8d916de6b0882e192bd6d25ab09ac982e3079aba" Action: ACTION_SUBSCRIBE_PRIVATE

OS: ubunto 20.04 and Windows 10

This is another transaction in the same block which also does not have a checkpoint: TX hash: "ac7ddefa0efb21606014f0ffe5bdaa890da9dd59c59922c51d0eb72582ecb0c9" Code: 8 Type: 303

Another transaction on the same block: TX hash: "7fdcd94e189ff9829ccf8dca264f7b5577c2b7d52faa283ecea3917ec112e0ca" Code: 8 Type: 303

There are quite a few ACTION_SUBSCRIBE_PRIVATE transactions in this block which fail as duplicate: TX hash: "d7ab57b7dbcc5383b38ab6dd5e1f7e7daa622e715f85d1648638168b6d7f8703"

I can find none of these errors in my debug.log, it's current and has been steady since the release of 20.12, Window 11

Did you download a checkpoint or perform a complete re-sync of the block chain? This is only seen during a re-sync.

I created a fix of the checkpoint/main.sqlite file here: https://github.com/tawmaz/pocketnet.core/commit/e79eb6fb96ed025bf04c5bf1a98a3e6be9d6592f

I will submit a pull request once I am able to sync both my nodes past block 419213.

I did not but for the last several hours (as I slept) it has been stuck on this:
