unknown 0d8f353b93 Fix for bug #29420: crash with show and purge binlogs
Problem: in case of failed 'show binlog events...' we don't inform that 
the log is not in use anymore. That may confuse following 'purge logs...'
command as it takes into account logs in use.

Fix: always notify that the log is not in use anymore.


mysql-test/r/rpl_rotate_logs.result:
  Fix for bug #29420: crash with show and purge binlogs
    - test result.

    - test case.
sql/sql_repl.cc:
  Fix for bug #29420: crash with show and purge binlogs
    - always zero thd->current_linfo at the end of the mysql_show_binlog_events().

# - Automatic binary log rotation
# - Ensure that temporary tables works over flush logs and binary log
# changes
# - Test creating a duplicate key error and recover from it
