wait_for_slave_io_error.inc

# ==== Purpose ====
#
# Waits until the IO thread of the current connection has got an
# error, or until a timeout is reached. Also waits until the IO
# thread has completely stopped.
#
#
# ==== Usage ====
#
# --let $slave_io_errno= NUMBER [, NUMBER ...] [# comment]
# [--let $show_slave_io_error= 1]
# [--let $slave_io_error_is_nonfatal= 1]
# [--let $slave_io_error_replace= REGEX]
# [--let $rpl_debug= 1]
# [--let $slave_timeout= NUMBER]
# --source include/wait_for_slave_io_error.inc
#
# Parameters:
#   $slave_io_errno
#     The expected IO error numbers. This can be either a single
#     number, or a comma-separated list of numbers. Examples:
#       --let $slave_io_errno= 1040, 1053, 2002, 2003, 2006, 2013
#       --let $slave_io_errno= 1593 # ER_SLAVE_FATAL_ERROR
#     It is allowed to add a comment at the end of the line, and it
#     is strongly advised to put the symbolic name of the error in
#     this comment, like the example above.
#     (After BUG#41956 has been fixed, this will be required to be
#     symbolic names instead of numbers.)
#
#   $show_slave_io_error
#     If set, will print the error to the query log.
#
#   $slave_io_error_is_nonfatal
#     By default, we wait for the slave IO thread to stop completely
#     (i.e., until Slave_IO_State is empty).  If this variable is set,
#     then we don't wait. This is useful if the error is non-fatal
#     (e.g., temporary connection error) and does not cause the slave
#     IO thread to stop.
# 
#   $slave_io_error_replace
#     If set, one or more regex patterns for replacing variable
#     text in the error message. Syntax as --replace-regex
#
#   $slave_timeout
#     See include/wait_for_slave_param.inc
# 
#   $rpl_debug
#     See include/rpl_init.inc
