Status query on killed mysql connection results in segmentation fault (Bug #738) Added MAX_PASSWORD_LENGTH. This increased master-slave passwords to 32 bytes (Bug #766) Fixed server crash on purge master logs or show master logs when binlog is off. (Bug #733)

BUG#2428 "--old-rpl-compat is broken": I remove the --old-rpl-compat which produces broken binlogs readable neither by 4.0 nor by 3.23. This option is a leftover of the early replication of 4.0.0, when it was still partly compatible with 3.23. I explained this to the user in the bug report.

extern my_bool opt_show_slave_auth_info;
Fixed searching after ssl directories. Fixed that GRANT ... REQUIRE options are not forgot when doing new GRANT Changed fn_ext to point at first '.' after directory. FLUSH LOGS removed numerical extension for all future update logs. Fixed the mysqld --help reports right values for --datadir and --bind-address --log-binary=a.b.c now properly strips of .b.c Fix that one can DROP UDF functions that was not loaded at startup Made AND optional in REQUIRE Added REQUIRE NONE

Here comes a nasty patch, although I am not ready to push it yet. I will first pull, merge,test, and get it to work. The main change is the new replication code - now we have two slave threads SQL thread and I/O thread. I have also re-written a lot of the code to prepare for multi-master implementation. I also documented IO_CACHE quite extensively and to some extend, THD class.

int cmp_master_pos(const char* log_file_name1, ulonglong log_pos1,
const char* log_file_name2, ulonglong log_pos2);
Lots of code fixes to the replication code (especially the binary logging and index log file handling) Fixed bugs in my last changeset that made MySQL hard to compile. Added mutex around some data that could cause table cache corruptions when using OPTIMIZE TABLE / REPAIR TABLE or automatic repair of MyISAM tables. Added mutex around some data in the slave start/stop code that could cause THD linked list corruptions Extended my_chsize() to allow one to specify a filler character. Extend vio_blocking to return the old state (This made some usage of this function much simpler) Added testing for some functions that they caller have got the required mutexes before calling the function. Use setrlimit() to ensure that we can write core file if one specifies --core-file. Added --slave-compressed-protocol Made 2 the minimum length for ft_min_word_len Added variables foreign_key_checks & unique_checks. Less logging from replication code (if not started with --log-warnings) Changed that SHOW INNODB STATUS requre the SUPER privilege More DBUG statements and a lot of new code comments

LOAD DATA INFILE is now replicated properly, except for cleanup on Stop event and bugs the test suite could not catch Did some big restructuring of binlog event classes - most important change is that now each event class has exec_event method and one does not need to modify slave core code to add a new event.
