+# Bug #10901 Analyze Table on new table destroys table
+# This is minimal test case to get error
+# The problem was that analyze table wrote the shared state to the file and this
+# didn't include the inserts while locked. A check was needed to ensure that
+# state information was not updated when executing analyze table for a locked table.
+# The analyze table had to be within locks and check table had to be after unlocking
+# since then it brings the wrong state from disk rather than from the currently
+# correct internal state. The insert is needed since it changes the file state,
+# number of records.
+# The fix is to synchronise the state of the shared state and the current state before
+# calling mi_state_info_write
