why adding into v6 struct and not defining v7 struct?
There was a problem hiding this comment.
This is a good point, when KVs were added to the catchpoint V6 format's chunk encoding in #4455 it did not require making a new catchpoint version V7, because the existence of the KV fields signaled they were there, and the merkle trie implementation was updated to include KVs as a possible node type for the trie. So the KVs got hashed along with accounts and resources, and overall the verification scheme was the same as existing V6, so it was not a bump to V7. Once the KV consensus flag flipped over, then KVs would be populated in catchpoint files.
Later state proof recovery was added to catchpoints, that was a whole new and separate hash added to the header and label-generating scheme, so it got bumped to V7 to support state proofs (plus a consensus flag so all nodes switched to the new hashing scheme at the same time). V7 did not touch the catchpointFileChunkV6 type at all so its name was left alone.
Similarly, I am adding two new hashes (onlineaccounts and onlineroundparams) so I am bumping the catchpoint file format to "V8" (like state proof recovery did with V7) but still extending the "catchpiontFileChunkV6" struct with two new fields (like KV for catchpoints did). I guess that is a weird thing to do.. and maybe I should make a new V8 type like you're suggesting

looks like it is time to switch from 7 return params to struct?

I got lost, we added online account into v8 label, didn't we?

why is there one more chunk? Added online accounts overgrew the max chunk size?

Summary
The new opcodes in #5984 require access to historical lookups of online account details and total circulation amounts. During catchpoint restore, replaying and evaluating old blocks bootstraps the tracker DBs. However transactions that use these opcodes will fail, since they need access to historical ledger amounts earlier than the horizon of the catchpoint snapshot. This PR adds the
onlineaccountsandonlineroundparamstailtables to the snapshot files, which provide online account lookup and total circulation amounts, respectively.Test Plan
Existing tests should pass — working on extending an existing catchpoint test to use the
voter_params_getandonline_stakeopcodes (similar to some catchpoint tests written for testing use of box opcodes).
