# ==== Purpose ====
#
# This is an auxiliary file that facilitates writing include/*.inc
# files. It has three purposes:
#
#  1. Store mtr's state at the beginning of the .inc file and restore
#     the state at the end. The following status is restored:
#
#     disable_warnings
#     disable_query_log
#     disable_result_log
#     disable_abort_on_errors
#     Current connection
#
#  2. This file also prints the name of the .inc file that sources
#     it. Only the name of the top-level .inc file is printed: if
#     file_1.inc sources file_2.inc, then this file only prints
#     file_1.inc.
#
#  3.  If the mysqltest variable $rpl_debug is set, then
#      this file will print:
#
#        ==== BEGIN include/<filename> ====
#
#      and end_include_file.inc will print
#
#        ==== END include/<filename> ====
#
#      These printouts are indented to make it easier to read the
#      result log.
#
#
# ==== Usage ====
#
# # At the beginning of include/my_file.inc:
# --let $include_filename= my_file.inc
# [--let $include_silent= 1]
# [--let $rpl_debug= 1]
# --source include/begin_include_file.inc
#
# # At the end of include/my_file.inc:
# --let $include_filename= my_file.inc
# --source include/end_include_file.inc
#
# Parameters:
#   $include_filename
#     The basename of the file: a file named /path/to/my_file.inc
#     should set $include_filename=my_file.inc.  This parameter
#     must be provided both for begin_include_file.inc and
#     end_include_file.inc.
#
#   $include_silent
#     By default, the following string is printed to the result file:
#       include/$include_filename
#     If this variable is set, this printout is inhibited.
#
#   $rpl_debug
#     If set, this script will print the following text:
#      ==== BEGIN include/$include_filename.inc ====


# Print 'include/$include_filename', but only when invoked from
# the top-level. We don't want to print
# 'include/$include_filename' from all files included
# recursively.

if ($rpl_debug)
{
  --echo $_include_file_indent==== BEGIN include/$include_filename ====
  # Print this text (just once) to prevent checking in result files containing
  # debug info.
  if (!$printed_this_should_not_be_checked_in)
  {
    --echo DO_NOT_CHECK_IN_THIS_LINE: \$rpl_debug should only be used for debugging. Never check in a test that has $rpl_debug=1.
    --let $printed_this_should_not_be_checked_in= 1
  }
