* Stop negotiating pivot if peer repeatedly replies w/usesless answers why: There is some fringe condition where a peer replies with legit but useless empty headers repetely. This goes on until somebody stops. We stop now. * Rename `missingNodes` => `sickSubTries` why: These (probably missing) nodes represent in reality fully or partially missing sub-tries. The top nodes may even exist, e.g. as a shallow sub-trie. also: Keep track of account healing on/of by bool variable `accountsHealing` controlled in `pivot_helper.execSnapSyncAction()` * Add `nimbus` option argument `snapCtx` for starting snap recovery (if any) also: + Trigger the recovery (or similar) process from inside the global peer worker initialisation `worker.setup()` and not by the `snap.start()` function. + Have `runPool()` returned a `bool` code to indicate early stop to scheduler. * Can import partial snap sync checkpoint at start details: + Modified what is stored with the checkpoint in `snapdb_pivot.nim` + Will be loaded within `runDaemon()` if activated * Forgot to import total coverage range why: Only the top (or latest) pivot needs coverage but the total coverage is the list of all ranges for all pivots -- simply forgotten.
