Fix eth_getLogs returning wrong blockHash (issue #1)

[naninu123]

Summary

Fixes #1 — eth_getLogs returns the wrong blockHash for logs on XDPoS.

Root cause

GetLogs and GetFilterLogs in eth/filters/api.go return logs straight from filter.Logs(), which carries the receipt's blockHash. On XDPoS that receipt hash is incorrect. The polling path GetFilterChanges already corrects this with core.GetCanonicalHash (the "XinFinOrg#208" fix), but GetLogs/GetFilterLogs were missed — so eth_getLogs keeps returning the wrong value while eth_getFilterChanges returns the right one.

Fix

Apply the same canonical-hash correction in GetLogs and GetFilterLogs:

for _, log := range logs {
    log.BlockHash = core.GetCanonicalHash(api.chainDb, log.BlockNumber)
}

Verified the package compiles (go build ./eth/filters/).

Example

For block 0x22b2277, eth_getLogs now returns 0xe8ec0bfc021f839fd0a69ae89689e309632af2cc434e8a096732068f0736864b (matches explorer) instead of the previously wrong 0x194a513ea40c94fccaca470cccb24c2ff3bd6398dec9a04e3eb3a4bfef8a330e.
