This PR changes the chain view update mechanism of the log filter. Previously the head updates were all wired through the indexer, even in unindexed mode. This was both a bit weird and also unsafe as the indexer's chain view was updates asynchronously with some delay, making some log related tests flaky. Also, the reorg safety of the indexed search was integrated with unindexed search in a weird way, relying on `syncRange.ValidBlocks` in the unindexed case too, with a special condition added to only consider the head of the valid range but not the tail in the unindexed case. In this PR the current chain view is directly accessible through the filter backend and unindexed search is also chain view based, making it inherently safe. The matcher sync mechanism is now only used for indexed search as originally intended, removing a few ugly special conditions. The PR is currently based on top of https://github.com/ethereum/go-ethereum/pull/31642 Together they fix https://github.com/ethereum/go-ethereum/issues/31518 and replace https://github.com/ethereum/go-ethereum/pull/31542 --------- Co-authored-by: Gary Rong <garyrong0905@gmail.com> |
