fix quickswapv3 tick - #47
Conversation
WalkthroughThe change adds selectable compressed tick-table indexing for Algebra V1 providers, enables it for QuickSwap V3, accepts zero pool fees, increases Rain log-fetch windows from 5 to 100 blocks, and corrects reserve fallback sizing. ChangesRain router updates
Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~10 minutes Change: Bug fix Merge Risk: 🟡 Moderate · up to Historical pool updates can become incomplete when an RPC endpoint rejects an oversized log request, while the fetcher still advances pool state. Fix the batching boundary and failure-state handling before merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

348-348: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick winUpdate the log-slice comment.
Line 348 still says that requests use 5-block slices, but the implementation now uses 100-block slices. Update the comment, or reference a shared slice-size constant so the documentation cannot drift from lines 354-355 and 366.

356-357: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winKeep each log request within 100 inclusive blocks and preserve the last successful boundary.
RainDataFetcher.updatePoolspasses inclusive bounds toPublicClient.getLogs. The current condition sends 101 blocks whenuntilBlock - fromBlockSlice === 100n. A rejected first slice also leavesuntilBlockat the requested target, soafterProcessLogcan succeed and setpool.blockNumberto a block whose logs were not processed.Use an exclusive slice boundary, return without advancing state when no slice succeeds, and pass only the last successful boundary to
afterProcessLogandpool.blockNumber.Proposed boundary-safe change
- // get logs in slices of 5 blocks to follow paging instructions from standard evm rpc specs + // get logs in slices of at most 100 inclusive blocks let fromBlockSlice = fromBlock const logsPromises = [] const blockNumberSlices = [] - while (fromBlockSlice < untilBlock) { - let toBlock = untilBlock + 1n - if (fromBlockSlice + 100n < untilBlock) { - toBlock = fromBlockSlice + 100n - } + while (fromBlockSlice <= untilBlock) { + const toBlock = + fromBlockSlice + 100n <= untilBlock + 1n + ? fromBlockSlice + 100n + : untilBlock + 1n blockNumberSlices.push(toBlock) logsPromises.push( this.web3Client.getLogs({ ... - fromBlockSlice += 100n + fromBlockSlice = toBlock } // await logs and sort them from earliest block to latest const logsResults = await Promise.allSettled(logsPromises) + let processedUntilBlock: bigint | undefined ... if (typeof blockNumberSlices[i] === 'bigint') { - untilBlock = blockNumberSlices[i] + processedUntilBlock = blockNumberSlices[i] } ... } + if (processedUntilBlock === undefined) return false ... - this.providers.map((p) => p.afterProcessLog(untilBlock!)), + this.providers.map((p) => p.afterProcessLog(processedUntilBlock!)), ... - pool.blockNumber = untilBlock! + pool.blockNumber = processedUntilBlock!Add boundary tests for 99, 100, and 101 block differences. Add a rejection test that checks the requested ranges and confirms that pool state does not advance beyond the last successful slice.
