# === Purpose ===
#
# Verify that disk full/out of space errors generated during the flush
# stage of binlog commit are properly handled by the server.
#
# === Implementation ===
#
# 1) Simulate the disk full scenario using dbug simulations so that
#    every alternate statement fails with 'No Space Error'.
# 2) With binlog_error_action= ABORT_SERVER, prepare a transaction
#    and perform the following operations.
#    2.1) Disconnect
#    2.2) Rollback
#    2.3) Commit
# 3) Repeat step 2 with binlog_error_action= IGNORE_ERROR.
#
# === References ===

# Bug #27399620 BINLOG AND ENGINE BECOME INCONSISTENT WHEN BINLOG CACHE FILE
# GETS OUT OF SPACE
