Handle removed logs in filter changes and add geth compatibility field #8796

sorpaas · 2018-06-05T09:47:21Z

Fixes #6880. This PR adds two things:

Add removed field, equivalent to log.type == "removed", for geth compatibility.
Handle reorg removed logs in filter. We do this by keeping track of the current polling block hash. Whenever log changes are requested, we check whether this block hash is on the canon chain. If not, going through the parent hashes of the tracked block hash to find the canon chain, before getting a normal filter. Light client removed logs are disabled, as I think it's expensive to fetch this information.

Light client removed logs fetching is disabled. It looks expensive.

I updated this to address #6880 (comment), handling removed logs in filter changes.

Overall LGTM, just some minor grumbles.

Can you add documentation for this new parameter: "last seen block hash"?

Can we rename this to something like removed_logs or reorged_logs? Something other than canon_logs since we're returning logs that are not canon.

This doesn't affect the filter that's used below when getting pending logs. And it's overridden afterwards with current + 1.

My mistake. Filter from_block should be set after we alter block_number.
