- Backup data integrity is verified using Checksum for each table
- If checksum mismatch is found (for a table) after a backup sync, the table data is cleared and re-synced
- Moved backup sync module to backup/sync.js
- Fixed: checkForRatedSellers not using correct asset when checking for rated sellers
- Others: priceHistory is converted toFixed(3) before storing in DB. (As large/non-terminating decimals cause ambiguity btw nodes during checksum)
- Same sink is used across nodes (sink is generated only when exchange starts for the 1st time)
- Shares as encrypted before sending to nodes (also store encrypted share in DB)
- Load share/key from DB (if available) when node starts
- share-threshold is calculated based on number of alive nodes
- Fixed: Shamirs algo fails when threshold is less than 2 (used round-about)
- Fixed: Minor bugs
- Removed: Immutable table-type (Previously immutable tables are now considered as mutable tables in backup feature)
- Backup sync-data from master are temporally cached and then processed after receiving all sync-data
- Backup sync-data from cache are now processed in ordered manner (to prevent foreign key constrain error, repeated data, re-adding a deleted data)
- Updated SQL Schema
- Read blockchain for asset's initial price
- Transfer all tokens to new sink on master transfer
Other Improvements:
- Slave: close existing backup sync when master WS closes
- Updated SQL schema, updated SQL syntax as required
