Basic infrastructure for log file sync.
A fork is detected by comparing the hpfs log index file against the ledger.
Min and max ledger sequence hashes are sent to a full history node to request log history.
* Skip proposal and npl messages from non unl nodes
* Minor code comment change
* Resolved PR comments and Changed weakly connected status check
* Changed weakly connected status counter
* Added a comment
- The ledgers are stored in a sqlite database in ledger file system.
- Ledgers are organized in shards inside primary folder.
- Raw inputs are saved as shards inside blob folder. No input files are created if neither inputs nor outputs are available.
- Both last primary shard hash and last blob shard hashes are subjected to consensus and necessary sync operations are performed if out of sync.
- Hpfs sync support setting single sync targets from both ends of the list. (Targets set from front are prioritized).
- Contract and ledger syncs and serving are performed independently.
- Creating two separate hpfs folders for contract and ledger file systems (contract_fs and ledger_fs).
- Added separate mounts for contract and ledger file systems.
- Added separate instances for contract serving and ledger serving.
- Added separate instances for contract syncing and ledger syncing.
- Modified cluster creating script to accompany folder name changes in contract folder.
* Refactoring hpfs code to a class so it can support multiple mounts.
* Refactoring hpfs serve into a class to support mulitiple mount serving.
* Refactoring hpfs sync into class to support multiple instances.
* Code improvements in hpfs_sync.
* Taking a sync target list for hpfs syncing target set.
* Terminology changes from state to hpfs.
* Syncing hpfs parents in priority order.
* Changing how the hash is calculate in hpfs response validate check.
Npl messages are forwarded and broadcasted only to trusted nodes if npl flag is set to private. If public, messages are broadcasted to all the connected peers.
Consensus proposals are forwarded and broadcasted only to trusted nodes if consensus flag is set to private. If public, proposals are broadcasted to all the connected peers.
* Adding pubkey in binary to comm sessions and is_unl flag to peer sessions.
* Removing display_name overloads and populating pubkey in user session.
* Changing peer session lookup key from uniqueid to pubkey (binary).
* Added contract id config.
* Verify contract id with user/peer challenge.
* Updated cluster scripts.
* Updated node client lib for contract id verification.
* Introduced self comm channel instead of loopback websocket.
* Introduced comm_session and comm_server inheritance hierarchy.
* Separated peer session and user session classes.
* Increased stage time window.
* Introduced central state tracker.
* Used shared mutex for target state update.
* Refactored lcl and state sync checks in consensus.
* lcl/state sync loop wait time improvements.
* Forward others' messages only to the weakly connected nodes instead of broadcasting to all the connected peers.
* Announcing connected status depends on a threshold to other connected peers.
* Forwarding messages of weakly connected peers to other peers.
* Implemented feeding and broadcasting npl messages from the contract execution in real-time.
* Replaced npl pipe with domain sockets.
* Refactored npl read and write in nodejs echo contract
