# ==== Purpose ====
|
|
#
|
|
# Verify that a transaction with wrong checksum is trimmed off from
|
|
# the binary log when the server restarts and executes recovery. Such
|
|
# recovery is executed if the server restarts after a crash.
|
|
#
|
|
# ==== Method ====
|
|
#
|
|
# 1. Inject a wrong checksum using debug code.
|
|
# 2. Crash server using debug_sync
|
|
# 3. Restart server
|
|
# 4. Show contents of binary log.
|
