This bug happens when using galera, max_tmp_session_space_usage and a transaction that uses temporary file of a size between 'binlog-cache-size' (default 32K) and 64K followed by a change user command. In the case of a transaction of size between 32k and 64k, the server don't truncate the binary log file on disk to speed up things, which is fine. The bug was that change_user() reset the tmp_space_used variable and the next time the temporary_file was truncated, we got a negative value for tmp_space_used, which caused the error "Local temporary space limit reached". Fixed by not resetting tmp_space_used in init(), which is called by change_user(). Other things - Truncate binary log cache files when change_user() is called. This makes the new users session not depending on log file sizes by previous user. - Some new ASSERT and DBUG_ENTER - Fixed typo in DBUG output in ma_pagecache.c |
