- Changed reading of config file so that one can use a separate config
file for [mysqld_multi] also. In other words --config-file=file will
read group [mysqld_multi] from this file, earlier it wouldn't have.
as we transform the 3.23 Load_log_event into a 4.0 Create_file_log_event which is one
byte longer, we need to increment event_len. The bug was that we did not increment it,
so later in code the end 0 was not seen so there was for example a segfault in
strlen(fname) because fname was not 0-terminated.
Other problems remain in 3.23->4.0 replication of LOAD DATA INFILE but they are less serious:
Exec_master_log_pos and Relay_log_space are incorrect. I'll document them.
They are not fixable without significant code changes (if you fix those problems in 4.0,
you get assertion failures somewhere else etc), * which are already done in 5.0.0 *.
Fix a glitch reported by Philippe Lewicki on the general mailing list: do not print a warning to the .err log if read_key fails with a lock wait timeout error 146
too big by 6 bytes. So I add code to substract 6 bytes if the master is 3.23.
This is not perfect (because it won't work if the slave I/O thread has not
noticed yet that the master is 3.23), but as long as the slave I/O thread
starts Exec_master_log_pos will be ok.
It must be merged to 4.1 but not to 5.0 (or it can be, because of #if MYSQL_VERSION_ID),
because 5.0 already works if the master is 3.23 (and in a more natural way:
in 5.0 we store the end_log_pos in the binlog and relay log).
I had to move functions from slave.h to slave.cc to satisfy gcc.
Add assertions to check that we do not go out of bounds of io thread status array
os0file.c:
Fix memory corruption (assertion failure on line 244 of sync0sync.c) reported by Miguel in a Windows build of MySQL-4.1.2. The bug is present in all InnoDB versions in Windows, but it depends on how the linker places a static array in srv0srv.c, whether the bug shows itself. 4 bytes were overwritten with a pointer to a statically allocated string: 'get windows aio return value'.
"Running ANALYZE TABLE on bdb table inside a transaction hangs server thread"
1. added new status HA_ADMIN_REJECT and processing of it in mysql_admin_table
2. got ha_berkley::analyze to return HA_ADMIN_REJECT if there are any
transactions with the table..
