# 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/master-slave-reset.inc

|
|
|
|
# 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:
