Julien Pivotto	4e5b1722b3	Move away from testutil, refactor imports (#8087 ) Signed-off-by: Julien Pivotto <roidelapluie@inuits.eu>	4 years ago
Brian Brazil	073e93c768	Gracefully handle unknown WAL record types. (#8004 ) As we're looking to expand what's in the WAL, having old Prometheus servers ignore the new record types rather than treating them as corruption allows for better upgrade/downgrade paths. Adjust some tests accordingly, so they're still testing what they're meant to test. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	4 years ago
