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.
I had not corrected these languages.
As it has been discussed with the docs team, the new messages will be merged
to 4.1, and then will be translated in 4.1 (they will remain in English
in 4.0).
Added support for lower_case_table_names=2, which is to be used on case insensitive file systems.
This tells MySQL to preserve the used case of filenames and database names to make it esier to move files between cases sensitive can case insensitive file systems (like Windows and Linux)
more general message when slave can't start because of incorrect
replication information, the previous one was sometimes a misleading
indication (i.e. sometimes the problem had nothing to do with
system permissions).
The perfect fix would be to report the exact error to the client
(instead of pointing the client to the error log); this is a bit
of work so it's more a development task:
WL#1088 "Move all hardcoded messages of replication to share/errmsg.txt".
I was not able to modify the errmsg.txt in these sql/ subdirectories:
danish
dutch
german
italian
portuguese
russian
spanish
swedish
ukrainian
"EE_ error codes (EE_DELETE, EE_WRITE) end up in the binlog, making slave stop".
The problem was that during execution of the command on the master, an error
can occur (for example, not space left on device, then mysqld waits and when
there is space it completes successfully: so finally it worked but the error
EE_WRITE remains in thd->net.last_errno and thd->net.last_error).
To know if finally the command succeeded, we test the 'error' variable in
every place, and if it shows no failure we reset thd->net.last_err* using
the function THD::clear_error() which is backported from 4.1.
A new test to see if now only real errors get to the binlog (note: the test
uses "rm").
Also a bit of memory free/alloc saving in log_event.cc (do not free the whole
mem_root after every query in the slave SQL thread: we can keep the initial
block of it; which will be freed when the thread terminates).
Don't dump data for MRG_ISAM or MRG_MYISAM tables. (Bug #1846)
Ensure that 'lower_case_table_names' is always set on case insensitive file systems. (Bug #1812)
One can now configure MySQL as windows service as a normal user. (Bug #1802)
Database names is now compared with lower case in ON clause when lower_case_table_names is set. (Bug #1736)
IGNORE ... LINES option didn't work when used with fixed length rows. (Bug #1704)
Change INSERT DELAYED ... SELECT... to INSERT .... SELECT (Bug #1983)
