Parity Bridge is corrupting the database file

[peterjoel]

I'm running Parity-bridge, based on the current version of the README, using:

./parity-bridge/target/release/bridge --config config.toml --database db.toml

And my db.toml file is like this:

home_contract_address = "0x74A71bFb6C4903d79EbDd77C556D2d43A9346BdD"
foreign_contract_address = "0xD6fE4c32ADDe8e4b5eD6272Ecb5c434Dc7b120c4"
home_deploy = 2025251 # block number at which the contract was created for home contract you can find in `bridgeDeploymentResults.json`
foreign_deploy = 6923247 # block number at which the contract was created for foreign contract you can find in `bridgeDeploymentResults.json`
checked_deposit_relay = 2025251 # last checked deposits events on Home network
checked_withdraw_relay = 6923247 # last checked withdraw events on Foreign network
checked_withdraw_confirm = 6923247 # last checked withdraw events on Foreign network

However, once the parity-bridge process starts, the file gets corrupted. It looks like this:

home_contract_address = "0x74a71bfb6c4903d79ebdd77c556d2d43a9346bdd"
foreign_contract_address = "0xd6fe4c32adde8e4b5ed6272ecb5c434dc7b120c4"
home_deploy = 2025251
foreign_deploy = 6923247
checked_deposit_relay = 2026365
checked_withdraw_relay = 6924041
checked_withdraw_confirm = 6924041
loy = 6923247 # block number at which the contract was created for foreign contract you can find in `bridgeDeploymentResults.json`
checked_deposit_relay = 2025251 # last checked deposits events on Home network
checked_withdraw_relay = 6923247 # last checked withdraw events on Foreign network
checked_withdraw_confirm = 6923247 # last checked withdraw events on Foreign network

The Home and Foreign account balances show as zero, even though I transferred ETH into them, and I suspect this is the cause.

does the problem occur with https://github.com/paritytech/parity-bridge/ or https://github.com/poanetwork/parity-bridge/? could you please move the issue to the repo it applies to : )

is it possible you were running two bridge processes?

could you please provide:

• the commit you built from
• your config.toml

thanks for filing this. definitely needs to get fixed

@peterjoel try removing comments #... from db.toml

@peterjoel could you post the output of running ./parity-bridge --help

[peterjoel]

I assume you mean:
