This +# would cause one byte shorter event end_log_pos. The ultimate +# impact was that it would make fixing the position in +# MYSQL_BIN_LOG::write_cache bogus or end up in an infinite loop. +# +# HOW +# === +# +# Checking that the patch fixes the problem is done as follows: +# +# i) one table with m_field_metadata sized at 290 +# ii) an insert is performed; +# iii) the logs are flushed; +# iv) mysqlbinlog is used to check if it succeeds. +# +# In step iv), before the bug was fixed, the test case would fail +# with mysqlbinlog reporting that it was unable to succeed in +# reading the event. + +-- source include/master-slave.inc +-- source
