# ==== Purpose ====
#
# Validate that when option `xa_detach_on_prepare` is enabled an XA transaction
# prepared on a source by a client thread becomes detached from that thread and
# can be committed on another source.
#
# ==== Requirements ====
#
# R1. It must be possible to commit an XA transaction on a tology node that
# is not the node where the transaction was originally prepared at.
#
# ==== Implementation ====
#
# 0. The test requires 2 servers in an asynchronous circular
# replication topology 1->2->1
# server1: source of server2
# server2: source of server1
# 1. On server1 enable option `xa_detach_on_prepare` for current session.
# 2. On server1 create a table.
# 3. On server1 create and prepare an XA transaction which inserts a value on
# the table.
# 4. On server2 commit the XA transaction.
# 5. Verify that insert was replicated to server1.
# 6. Cleanup
#
