chore(perf): improve getting sector info perf - #7491
Conversation
WalkthroughThe PR adds direct single-sector lookup for miner state, updates RPC and state-manager callers, changes sector expiration lookup to use the sector location, consolidates version-specific sector loading, adds lookup regression tests, and uses cacheless deal proposal iteration. ChangesSector lookup and loading
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The performance refactor is mergeable with explicit owner follow-up: error diagnostics can be improved, and an accessor currently exposes an RPC type through the state-manager layer, creating a bounded integration risk.

load_sectors_extis now identical toState::load_sectors; delegate instead of expanding the macro twice.After this change, the body at line 13 matches
State::load_sectorsinsrc/shim/actors/builtin/miner/mod.rsline 238 exactly, and both take the same arguments and return the same type. Keeping two expansions ofload_sectors_by_version!duplicates the generated code and lets the two entry points drift apart later. Delegate the trait method to the inherent method and keep one expansion site.Also note that the macro propagates every store and decode error with a bare
?. The previous implementation added context. Consider adding.context(...)at the call sites so failures identify the miner state version and the sectors root.♻️ Proposed delegation

1680-1697: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winStrengthen the test: assert the boundary result and cover the present-sector path.
Line 1696 discards the result with
let _ =. The test then passes even ifu64::MAXreturnsErr. Assertis_none()for that input as well, or assert the exact expected outcome.The test also covers only the absent path on
State::V18. The PR changes lookup behavior forStateSectorGetInfo, so a case that commits one sector and asserts thatget_sectorreturns that sector would protect the main regression risk: a wrong sector returned for a valid number.💚 Proposed change for the boundary assertion

get_sectorRPC-facing or add a lossless boundary conversion.
StateManager::get_sector_inforeturns this value directly toStateSectorGetInfo; changing onlysrc/rpc/methods/state.rsis insufficient. The shim and RPC types also differ: the RPC type hasflags,power_base_epoch, anddaily_fee, while the shim type hasreplaced_sector_ageandsimple_qa_power. Preserve these fields if you move the conversion. Otherwise, document whyget_sectorreturns the RPC type.🤖 Prompt for AI Agents
