By default, the ASCII reader does not fail on errors anymore. If there is a problem parsing a line, a reporter warning is written and parsing continues. If the file is missing or can't be read, the input thread just tries again on the next heartbeat. Options have been added to recreate the previous behavior... const InputAscii::fail_on_invalid_lines: bool; and const InputAscii::fail_on_file_problem: bool; They are both set to `F` by default which makes the input readers resilient to failure.
