# MDEV-32051 : Failed to insert streaming client
|
|
#
|
|
# Test outline:
|
|
# To reproduce we need a autocommit INSERT with streaming enabled,
|
|
# and a conflicting TRUNCATE.
|
|
# The INSERT is BF aborted by TRUNCATE during replication of the commit
|
|
# fragment, so that the INSERT must be rolled back replayed. During
|
|
# replay it fails certification, finally the statement is retried and
|
|
# succeeds. If bug is present, the streaming client for the INSERT does
|
|
# not get deleted after replay, causing the warning (or assert in debug builds)
|
|
# when retrying attempts to create the same streaming client with the same id.
|
