nodeDB.querySeeds was not safe for concurrent use but could be called concurrenty on multiple goroutines in the following case: - the table was empty - a timed refresh started - a lookup was started and initiated refresh These conditions are unlikely to coincide during normal use, but are much more likely to occur all at once when the user's machine just woke from sleep. The root cause of the issue is that querySeeds reused the same leveldb iterator until it was exhausted. This commit moves the refresh scheduling logic into its own goroutine (so only one refresh is ever active) and changes querySeeds to not use a persistent iterator. The seed node selection is now more random and ignores nodes that have not been contacted in the last 5 days. |
