Parity-ethereum: Error reading node table file 1.8.8

[stone212]

_Before filing a new issue, please provide the following information._

I'm running:

• Which Parity version?: 1.8.8 stable
• Which operating system?: Linux
• How installed?: binary (amd64)
• Are you fully synchronized?: yes
• Which network are you connected to?: private blockchain
• Did you try to restart the node?: yes

Running a node that was previously running 1.7.11 but is now upgraded to 1.8.8.

When starting Parity from the command line this error comes up directly after displaying the ETH price:

Error reading node table file: ErrorImpl { code: Message("missing fieldattempts"), line: 3, column: 185 }

If I delete .parity/chains//network/nodes.json and restart, there is no error.

I assume this has to do with the new nodes.json format but I am not sure if this means that 1.8.8 can't read the old format. Is it required that I manually delete the file as part of the upgrade to 1.8.8?

+ 1. I also got this when updated to 1.8.8.

But it has not affected the syncing in any way or form, mainnet continues to sync normally.

That's expected since we made some changes to the json format. Yes, 1.8.8 won't be able to read the old format and your existing nodes.json file will be ignored but there's no action needed on your part.

@andresilva Yes you are correct. I added it as an issue so the error could me made more clear. Or called a "warning" instead. For a systems administrator, the word "Error" means "Danger Will Robinson".
