# ==== 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_count_condition= CONDITION]
# [--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_count_condition
# Instead of asserting that the selected lines match
# $assert_match, assert that $assert_count_condition is met for
# the number of matching lines. The 'assert_count_condition'
# must be a valid Perl expression, which consists of an operator and
# right side expression - an integer.
# For example, 'assert_count_condition' may be <= 1.
#
# $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).
