Contents

Synopsis

ExitFailure

The exit code to return when terminating with an exception.

To be used in the ExitFailure constructor of ExitCode .

Note that a node will never turn shut down itself, it is meant to run forever, so it will always terminate with an ExitFailure .

Convert an ExitReason to an ExitFailure .

ExitReason

The reason of shutting down

Constructors

Killed	The node process was killed, by the `kill` command, `CTRL-C` or some other means. This is normal way for a user to terminate the node process. The node can simply be restarted.
ConfigurationError	Something is wrong with the node configuration, the user should check it. For example, for PBFT, it could be that the block signing key and the delegation certificate do not match.
WrongDatabase	We were unable to open the database, probably the user is using the wrong directory. See `DbMarkerError` for details.
DiskFull	The disk is full, make some space before restarting the node.
InsufficientPermissions	The database folder doesn't have the right permissions.
NoNetwork	There is a problem with the network connection, the user should investigate. TODO We're not yet returning this.
DatabaseCorruption	Something went wrong with the database, restart the node with recovery enabled.
Other	Some exception was thrown. The node should just be restarted.

Return the ExitReason for the given SomeException . Defaults to Other .
