Issuing 'FLUSH LOGS' does not close and reopen indexfile.
Instead a SEEK_SET is performed.
This patch makes index file to be closed and reopened whenever a
rotation happens (FLUSH LOGS is issued or binary log exceeds
maximum configured size).
mysql-test/suite/binlog/r/binlog_delete_and_flush_index.result:
Result file.
mysql-test/suite/binlog/t/binlog_delete_and_flush_index.test:
Test case.
sql/log.cc:
Added LOG_CLOSE_INDEX flag when calling MYSQL_BIN_LOG::close
from within MYSQL_BIN_LOG::new_file_impl (which should just be
called whenever a rotation is to happen - FLUSH LOGS issued or
binlog size exceeds the maximum configured).

# BUG#34582: FLUSH LOGS does not close and reopen the binlog index
|
|
# file
|
|
#
|
|
# WHAT
|
|
# ====
|
|
#
|
|
# We want to test that FLUSH LOGS closes and reopens binlog index
|
|
# file.
|
|
#
|
|
# HOW
|
|
# ===
|
|
#
|
|
# PREPARE:
|
|
# 1. create some binlog events
|
|
# 2. show index content, binlog events and binlog contents
|
|
# for mysql-bin.000001
|
|
# 3. copy the mysql-bin.000001 to mysql-bin-b34582.000001
|
|
# 4. change the index file so that mysql-bin.000001 is replaced
|
|
# with mysql-bin-b34582.000001
|
|
# 5. FLUSH the logs so that new index is closed and reopened
|
|
#
|
|
# ASSERTIONS:
|
|
# 1. index file contents shows mysql-bin-b34582.000001 and
|
|
# mysql-bin.000002
|
|
# 1. show binary logs shows current index entries
|
|
# 2. binlog contents for mysql-bin-b34582.000001 are displayed
|
|
# 3. Purge binlogs up to the latest one succeeds
|
|
# 4. SHOW BINARY LOGS presents the latest one only after purging
|
|
# 5. Purged binlogs files don't exist in the filesystem
|
|
# 6. Not purged binlog file exists in the filesystem
|
|
#
|
|
# CLEAN UP:
|
|
# 1. RESET MASTER
|
|
#
