# BUG#42749: infinite loop writing to row based binlog - processlist shows
# "freeing items"
#
#
# WHY
# ===
#
# This bug would make table map event to report data_written one
# byte less than what would actually be written in its body. 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.

# BUG#50018: binlog corruption when table has many columns
#
# Same test from BUG#42749, but now we generate some SQL which
# creates and inserts into tables with metadata size from 249
# to 258.
#
# The test works as follows:
# 1. SQL for several CREATE TABLE and INSERTS are generated
# into a file.
# 2. This file is then "sourced"
# 3. The slave is synchronized with the master
# 4. FLUSH LOGS on master
# 5. Compare tables on master and slave.
# 6. run mysqlbinlog on master's binary log
#
# Steps #5 and #6 assert that binary log is not corrupted
# in both cases: when slave is replaying events and when
# mysqlbinlog is used to read the binary log
--source include/rpl_reset.inc
-- connection master
# Create several tables with field_metadata_size ranging
# from 249 to 258 (so that we cover 251 and 255 range).
# This should exercise the switch between using 1 or 3
# bytes to pack m_field_metadata_size.
#
# Each varchar field takes up to 2 metadata bytes, see:
#
# Field_varstring::do_save_field_metadata (field.cc)
#
# The float field takes 1 byte, see:
#
# Field_float::do_save_field_metadata (field.cc)
