Protocol Team Pickup Notes

[tynes]

This issue is meant to track various in progress things that we don't want to forget about after the holidays. We will use the things documented in this ticket to seed the next kickoff meeting in the new year.

[protolambda]

1. Merge 1.14.12 geth upgrade (done, reviewed, ready to merge, but need an approval from Seb or Adrian + devnet rollout)
   • op-geth: all: update to geth v1.14.12 op-geth#452
   • monorepo: Updates to work with upstream geth v1.14.12 changes optimism#13002
2. L1-pectra support work
   • Clarify specs that 7702 txs are not supported for batch data reading
   • shared op-node/op-program tx-reading fix
   • op-node modifications to L1 RPC
   • op-program FP update
3. Kurtosis devnet needs to regularly run latest protocol changes. Focus is first on an L2-interop kurtosis devnet, but the non-interop kurtosis is still important too.
4. op-reth integration plans with interop (support for tx simulation and interop safety checks against op-supervisor RPC)

[vdamle]

• Working on fixing broken existing action tests with my changes for withdrawalsRoot in Isthmus: Updates for L2 withdrawals root in header optimism#12848. The common symptom appears to be a chain reorg that manifests when running action tests with the above code.
• New action tests added for Isthmus withdrawalsroot are working correctly.
• Also reading FMA doc for Holocene to get a sense of what we would need to add for Isthmus withdrawalsRoot feature.

[emhane]

• Upstreaming prereq changes required to verify l2tol1 storage root in pipeline sync Lay way for l2tol1 storage root verification in pipeline sync op-reth#16
• Enabled slimmed down CI in op-reth Skip reth binary tests op-reth#8
• Make use of workflow for interop kurtosis in op-reth CI L2-to-L1-message-passer op-node image for kurtosis-op op-reth#14, Add kurtosis-op-interop op-reth#15. For manual trigger only Remove cron job checks op-reth#11.

[sebastianst]

• Remaining superchain-ops tasks for Holocene FP upgrades
• Investigate derivation divergences observed during seq-window resets
• Related: improve seq-window timeout behavior of sequencer and batcher
  • review op-node: implement sequencer recover-mode optimism#13550
  • make batcher aware of sequencer being in seq-window recovery mode
  • revisit batcher throttling implementation
• review op-geth upstream merge all: update to geth v1.14.12 op-geth#452 Updates to work with upstream geth v1.14.12 changes optimism#13002

[geoknee]

For me pretty similar to Seb:

• remaining work on superchain ops for systemconfig upgrade post holocene activation
• helping to debug any possible derivation divergences observed during seq-window resets
• helping implement fixes to op-node and batcher to better deal with sequencing window expiry
• tidy up the mutex behaviour in the batcher, since this PR op-batcher: Fix concurrent map write optimism#13527 did it in a way that is less tidy than I would like.

[axelKingsley]

I had done this exercise on a notepad at home, tucked in my laptop, but for posterity it was:

• Supervisor Data Flow Refactor is almost done : interop, op-supervisor, op-node: Managed Mode optimism#13406
• Need to clean up final items
  • Integration of Controllers
  • New Tests
  • Run E2E tests and fix any new integration issues

When I get back, I'll be:

• Finishing the above feature branch and merge
• Cleaning up documents
• Updating the local devnet config

And then we have a list of work for the Stability Milestone

--

I am working through this now, I've now got the branch fully functional and now expanding test coverage before seeking approval/merge.

Mon, Jan 6, 2024 - Kickoff Meeting

(see above for more granular task lists)

Vinod - Resolved testing issues around Isthmus presumptioms about pre-Isthmus blocks. Added details around to ticket. Currently working on getting Kurtosis to work w/Isthmus local fork with Slipper and team.
Action Items: Looking for reviews & second eyes on his stuff.

George - See above for tasks but primarily supporting superchain and Holocene activation

Seb - Supporting Unichain and to get log access. Just waiting for a way to access the full logs via VPN to look into issues. Working with George on recovery mode for sequencer after incident. Also looking to get op-geth merges in.

Emilia - Is looking to pull in some folks around reth bug. Group suggested tagging a few folks who may have more context (clabby, etc)

Axel - Focused on supervisor and testing refactor which is nearly complete (see above for complete task list)

Aaron - Reminder that CDMX proofs spike is next 2 weeks so folks may be a little less communicative than usual but I can help with communication so ping me whenever!
