sync_state returns data is never updated on devnet

[devchenyan]

Bug Report

The data sync_state returned never changed on devnet

Current Behavior

Each request for sync_state returns the same result each time the ckb devnet node is started, with no updates to best_known_block_number, etc.

curl -X POST http://127.0.0.1:8114 \
-H 'Content-Type: application/json' \
-d '{ "id": 42, "jsonrpc": "2.0", "method": "sync_state", "params": [ ] }'

{"jsonrpc":"2.0","result":{"best_known_block_number":"0x42fa","best_known_block_timestamp":"0x18fc3f6de71","fast_time":"0x3e8","ibd":false,"inflight_blocks_count":"0x0","low_time":"0x5dc","normal_time":"0x4e2","orphan_blocks_count":"0x0"},"id":42}%

The result returned by the sync_state request is only updated after restarting the ckb devnet node

curl -X POST http://127.0.0.1:8114 \
-H 'Content-Type: application/json' \
-d '{ "id": 42, "jsonrpc": "2.0", "method": "sync_state", "params": [ ] }'

Expected Behavior

After starting the ckb devnet node, the results returned by the a request can be updated normally

Environment

• CKB version: 0.114.0 (0c8711e 2024-02-29)
• Chain: dev
• Operating system: macOS 13.6
• Arch: arm64
• Installation: GitHub Release

Additional context/Screenshots

@eval-exec Can you help with this?

[quake]

did you start a miner and mined new block successfully for this dev node?

[driftluo]

sync state only init with local on start, and will update on sync with other node, never with self mined, I think this is the reason. dev node never has network communicate

[eval-exec]

The purpose of best_known_block_number is to show which block with the highest total_difficulty among all peers connected to the current CKB node. Since the devchain you are running locally does not establish connections with other peers in the network, this value will not be updated.

yes
