ChangeSet
  1.2100 06/04/05 01:09:07 aivanov@stripped +3 -0
  Fixed BUG#13683: INSERT DELAYED into a view creates an infinite loop.
   The bug was caused by wrong behaviour of mysql_insert() which in case
   of INSERT DELAYED into a view exited with thd->net.report_error == 0.
   This blocked error reporting to the client which started waiting
   infinitely for response to the query.

  sql/sql_insert.cc
    1.185 06/04/05 01:09:02 aivanov@stripped +1 -1
    Fixed BUG#13683: INSERT DELAYED into a view creates an infinite loop.
     Changed mysql_insert(): delayed_get_table() applied to a view exits
     with ER_WRONG_OBJECT error (and with thd->net.report_error == 1) and
     in this case we must just exit from mysql_insert().  Prior to this
     change, instead of exiting open_and_lock_tables() was invoked which
     cleared thd->net.report_error to zero and caused the bug.

  mysql-test/t/insert.test
    1.22 06/04/05 01:09:02 aivanov@stripped +12 -0
    Added test case.

  mysql-test/r/insert.result
    1.23 06/04/05 01:09:02 aivanov@stripped +6 -0
    Fixed results for the added test case.
