# ==== Purpose ====
#
# Grep a file for a pattern, produce a single string out of the
# matching lines, and assert that the string matches a given regular
# expression.
#
# ==== Usage ====
#
# --let $assert_text= TEXT
# --let $assert_file= FILE
# --let $assert_select= REGEX
# [--let $assert_match= REGEX | --let $assert_count= NUMBER]
# [--let $assert_only_after= REGEX]
# --source include/assert_grep.inc
#
# Parameters:
#
#   $assert_text
#     Text that describes what is being checked. This text is written to
#     the query log so it should not contain non-deterministic elements.
#
#   $assert_file
#     File to search.
#
#   $assert_select
#     All lines matching this text will be checked.
#
#   $assert_match
#     The script will find all lines that match $assert_select,
#     concatenate them to a long string, and assert that it matches
#     $assert_match.
#
#   $assert_count
#     Instead of asserting that the selected lines match
#     $assert_match, assert that there were exactly $assert_count
#     matching lines.
#
#   $assert_only_after
#     Reset all the lines matched and the counter when finding this pattern.
#     It is useful for searching things in the mysqld.err log file just
#     after the last server restart for example (discarding the log content
#     of previous server executions).
